Abstract
A brush, such as a toothbrush, has a brushing head incorporating one or more rotatable brush inserts. The brushing head and the inserts both have a plurality of bristles extending therefrom, the bristles of the inserts being surrounded by the bristles of the brushing head. The inserts are retained in sockets within the brushing head, within which they may both rotate and move translationally, preferably undergoing an orbital motion around the socket. The inserts may move continuously or reciprocally. This motion of the inserts is generated by manual movement of the brush, for example while brushing a user's teeth. The inserts may be provided with toothed cogs that engage with recesses between teeth arrayed around an interior of each socket. The brush may include an electric motor powering a mechanism to vibrate the brushing head as a whole; however, this motor still does not drive the inserts.
Description
- The present invention relates to a mechanism for improving the action of brushes, and to brushes comprising such a mechanism. More particularly but not exclusively, it relates to manually-operated brushes, particularly toothbrushes, having improved brushing effectiveness.
- A conventional manual toothbrush has a general form that has changed little over time. A generally rectangular, generally flat brush head is supported by an elongate handle extending generally coaxially with a major axis of the rectangular head. A plurality of bristles extend from one face of the brush head, either perpendicularly to said face or with some or all bristles at a slight angle to the perpendicular. The lengths, materials, stiffness, angles and arrangement of the bristles has been varied greatly, but in each case the brush is used to clean a user's teeth by manual movement of the brush head across the teeth in a combination of longitudinal, lateral and circular movements.
- The manual toothbrush is simple to produce and requires only the muscular effort of the user to operate. However, its effectiveness is restricted by the effort that the user is willing or able to put into its use. For example, children may be unwilling to brush for the recommended time using a conventional brush (and not only children). It would therefore be beneficial if the manual toothbrush could be made more effective for a given degree of manual movement.
- Electrically-powered toothbrushes are well known, in which a brush head element is driven in an oscillatory rotational motion at a high brush stroke rate, compared with manual brushing. They are considered in many quarters to be more effective than manual toothbrushes. However, powered toothbrushes are much more complex and expensive to produce, compared to manual toothbrushes. They require periodic re-charging or replacement of batteries, so are relatively costly to run. Electrically-powered toothbrushes tend to be relatively heavy and bulky, and so are less convenient when away from home, e.g. when travelling.
- Considered from an environmental point of view, manually-operated toothbrushes do not use valuable electrical power resources, and use up little or no rare or expensive raw materials in their production. There is no need to dispose of used batteries, and the toothbrush is easier to deal with at the end of its useful life.
- It would therefore be beneficial to incorporate at least some of the performance advantages of an electrically-powered toothbrush into a brush that may be operated solely by being manipulated by its user.
- While the present invention will be described primarily in terms of toothbrushes, it is believed that analogous issues would be encountered with other forms of brush, such as those used for polishing, scrubbing or the like, and that solutions appropriate for toothbrushes may well be appropriate for such other forms of brush. Therefore, except where evident from the context, the term “brush” herein should be understood not necessarily to be limited to toothbrushes per se.
- It is hence an object of the present invention to provide a brush mechanism, and a brush containing such a mechanism, that provide improved brushing effectiveness relative to existing manually-operable brushes, while being operable solely by being moved by a user.
- According to the present invention, there is provided a brushing device comprising brush head means having bristle means extending from one face thereof and handle means fixedly mounted to said brush head means, wherein the brush head means comprises a fixed head element and at least one insert element so mounted to the fixed head element as to be rotationally movable with respect thereto, said fixed head element and the or each said insert element each having a plurality of said bristle means extending therefrom, and the bristle means of the fixed head element substantially surrounding those of the or each insert element.
- Preferably, the insert element is movably retained within socket means of the brush head means.
- Advantageously, the insert element is both rotationally and translationally movable within the socket means.
- Said translational movement may be generally perpendicular to an axis of rotation of the insert element.
- The insert element may be orbitally movable around the socket means.
- The insert element may be continuously movable around the socket means.
- The insert element may be constrained to oscillatory or reciprocating motion within the socket means.
- The insert element is preferably rotationally movable about an axis generally parallel to the bristle means.
- The insert element may be constrained to follow a hypocycloid or hypotrochoid path around the socket means.
- Preferably, the insert element is provided with first engagement means adapted to engage releasably with co-operating second engagement means of the fixed head element.
- Advantageously, said first and second engagement means act to transmit torque between the insert element and the fixed head element.
- Preferably, the insert element comprises cog means having a plurality of tooth means, each so projecting therefrom as to be engageable with co-operable recess means of the fixed head element.
- Advantageously, the fixed head element is provided with a plurality of said recess means.
- Each recess means of the fixed head element may be defined between adjacent pairs of a plurality of tooth means projecting therefrom.
- Said plurality of recess means may be disposed in an array extending around an interior of the socket means, optionally around a wall thereof.
- The insert element may comprise a plurality of insert bodies, each movable with respect to the or each other insert body.
- Each said insert body may be releasably engageable with an adjacent insert body.
- Each insert body of the insert element may be provided with a plurality of said bristle means extending therefrom.
- Optionally, one said insert body is engageable with co-operating engagement means of the fixed head element.
- Biasing means may be provided to bias the insert element or an insert body thereof into engaging contact with engagement means of the fixed head element.
- The brush head means may be provided with bearing means adapted to reduce friction between the insert means and the fixed head means.
- Preferably, the fixed head means is provided with retaining means for the insert means.
- Advantageously, said retaining means comprises lip means of the socket means.
- Said retaining means may comprise detent means.
- Said retaining means may comprise annular rim means projecting from the insert means into circumferential slot means of the socket means, or annular rim means projecting from an interior surface of the socket means into circumferential slot means of the insert means.
- Optionally, the brush head means is provided with a plurality of said insert elements.
- Preferably, the first and second engagement means comprise first gear means having outwardly-projecting tooth means engageable with second gear means having inwardly-projecting tooth means.
- Said second gear means may comprise an annular internal gear means.
- The insert means may comprise the first gear means and the fixed head means may comprise the second gear means.
- Alternatively, the fixed head means may comprise the first gear means and the insert means may comprise the second gear means.
- Optionally, the first gear means is engageable with third gear means which is engageable in turn with the second gear means.
- The insert element may be generally circular.
- The socket means may be generally circular.
- Alternatively, the socket means may be substantially elliptical.
- The socket means may comprise drainage means to release adventitious fluids therefrom.
- Seal means may be provided to exclude fluids from the socket means.
- The handle means may be detachably fixed to the brush head means.

FIG. 3 shows and illustrates the internal workings of the mechanism. As illustrated with the help ofFIG. 5 , the brush heads 2 are embodied within the housing of themain toothbrush head 1, the brush heads 2 have five adjoined teeth cog ends 10 which are in turn housed into the six invertedteeth cog apertures 6, which are incorporated within thebase 11 of the toothbrush head as shown inFIG. 4 .FIG. 5 shows a top washer orring 3 that can be partly seen on the surface, as shown inFIG. 1 . InFIG. 5 there is anotherring 12 that fits and locks within thering aperture 13 to keep the brush head securely within the housing of thetoothbrush head 1. -
FIG. 5 shows aguide 9 which protrudes from the tip of the bottom end of the brushhead cog part 10; thisguide 9 orbits around theguide 8 which is protruding in the opposite direction from thetoothbrush head base 11, thus encouraging thecog 10 to make an orbiting 7 and rotational movement when the consumer users the toothbrush in a circular motion against their teeth. Theguides - Shown in
FIG. 6 is a closer view of the motion of the mechanism in work, thebrush head cog 10 is centrally affixed to thebrush head 2, this is placed within theaperture 6 which is shaped to accommodate thecog 10. Similarly theaperture 6 is shaped as aninverted cog 6 which has more teeth that are in this case inverted, and has theguide 8 centrally protruding thus offsetting thecog 10, and thus thebrush head 2. This offsetting will cause thebrush head 2 to move in an orbiting movement and take the path as illustrated by the broken line 7. -
FIG. 7 shows the brushhead top ring 3 which is part of thebrush head 2, is on the underside of the toothbrush head surface 14, therings necessary apertures 13 to cater for this. - As shown in
FIGS. 8 to 12 there can bedifferent shape cog 10 andaperture 6 parts, of different sizes, with different amounts of teeth, angles, corners which will all influence and determine the orbital 7 and rotational movement, as well as the amount of rotation per manual toothbrush cycle carried out by the user. The same general principle of the rotating mechanism workings described above will apply with these differentshape cog part 10 andaperture 6 parts. - There are various forms and designs the toothbrush can take to help and encourage better cleaning,
FIGS. 13 to 16 shows example of just some of thevarious brush head 2 and bristle 4 formations that may be used.FIG. 17 shows just 2 brush heads. - Illustrated in
FIG. 18 is adetachable toothbrush head 1 part and handle 5, the femaletoothbrush head part 15 is attached to themale handle part 16 which has a series of rims incorporated in order to lock into thefemale part 15,FIGS. 19 to 21 illustrates some of the locking rims 17 that may be used. -
FIGS. 22A and 22B illustrate that atongue scrubber 18 may be incorporated on the bottom side or opposite of the toothbrush head, thetongue scrubber 18 is able to be incorporated as the mechanical parts are within the housing of thetoothbrush head 1. -
FIG. 23 shows a similar mechanical system to the one shown inFIG. 5 , however, the difference being that the cog system play a reverse role, to illustrate this themale cog 10 inFIG. 5 is now aninverted cog 19 as shown inFIG. 23 , and thus thecog aperture 6 which is part of thetoothbrush head base 11 inFIG. 5 , is now acog 20 or male part inFIG. 23 which fits into the brush head invertedcog 19 part. -
FIG. 24 is a closer look at the internal mechanism and the motion of the mechanism shown inFIG. 23 ; it also shows the orbital path in broken lines 7. The smallerbroken line circle 22 illustrates the orbital path guide 9 which is attached to theinverted cog 19 will take around guide 8 which is attached to thecog 20. -
FIG. 25 shows a similar system to shown inFIG. 23 but the difference being the lockingring 12 is at the base of the brush head invertedcog 19 part. Thering 12 may also be placed in other positions up or down along the outside ofinverted cog 19, and thus the positions of theapertures 13 in the toothbrush housing in the designs described, as well as being able to include one or more rings orwashers 12. There is also anaperture 21 to allow theinverted cog 19 space to move when in motion. - Referring to
FIG. 26 , as the toothbrush is operated in a circular motion theinverted cogs 6 will move in an orbital fashion around thebrush head cog 10.FIG. 28 shows theinternal handle 23 part that has thecog apertures 6 incorporated through it. Theinternal handle 23 connects to thehandle 5; thetoothbrush head 1 is free moving and is not physically adjoined to theinternal handle 23 and nor to thetoothbrush handle 5. The brush heads 2 are placed in a fixed position within two holes that go though theupper casing 27 of thetoothbrush head 1 to allow them to rotate only and not to make an orbital movement. Thecog 10 has anaxis 26 part at the bottom end which connects into thebase housing 11. Thetoothbrush head 1 has anaperture 25 surrounding theinternal handle 23 to allow for some looseness or slack in order for thecog apertures 6 to move around thebrush head cog 10 in an orbital motion, and thus rotating the brush heads 2 while doing so. -
FIG. 29 shows aninternal handle 23 withmale cog 20 parts, which is used in the toothbrush illustrated inFIG. 30 , the mechanism this time is reversed to the one shown inFIG. 26 in that the cog apertures 19 are built into the brush heads 2 and thecogs 20 are affixed to theinternal handle 23. Theinternal handle 23 andexternal handle 5 are adjoined, as well as this non-detachable version, a detachable toothbrush head may be applied as shown similarly inFIG. 26 , this applies to all toothbrushes described above. -
FIGS. 31 to 33 shows various brush heads that with differently positionedtop rings 3, andinner rings 12 that can be used for the toothbrush inFIG. 30 instead of thedouble washer ring 24 which is used inFIGS. 26 and 30 . There may be one or more locking rings 3, 12 incorporated at different positions, there also may be just one ring but this has to be below theupper casing 27 in order to lock the brush head securely within thetoothbrush head 1. Similar ring formations may be used for the brush heads inFIG. 26 providing there's no obstruction to the variableinternal handle 23. - The mechanical manual toothbrush is made from plastic material, rubber, metal material, bristle fibres, or from a combination of these materials.
- The mechanical manual toothbrush is either moulded or/and glued together, or conjoined by a series of small male and female clips or a combination thereof.
- All designs shown above can have one or more brush heads 2; the toothbrush heads may or may not include
bristles 4, thehandles 5 can be detachable or non-detachable. - The
guides - The
toothbrush head 1 including brush heads 2 may be attached to a standardnon-electrical handle part 5, or can also be used in conjunction with an motorisedelectrical handle 5 part, whereby the handle contains an electrical motor and vibrating part, this can be rechargeable or battery powered. -
FIG. 34 illustrates an exploded side view of the mechanical manual toothbrush where all components can be seen, with the bottom part being thetongue scrubber 18, which connects to thetoothbrush handle 5 andtoothbrush head 1 which are adjoined together as one part, this also has incorporated within theinverted cog aperture 6, thebrush head 2 is seated onto thetoothbrush head 1 ortoothbrush base 11 where thebrush head cog 10 is seated within theinverted cog aperture 6, thebrush head washer 3 rests on top of thetoothbrush head base 11. Theupper casing 27 which includes fixedbristles 4 is placed on top of the rest of the assembly where the brush head bristles 32 appear through theupper casing aperture 28. Theupper casing aperture 28 and thebrush head washer 3 are sized accordingly so thecog 10 is not openly exposed as the toothbrush and thus the mechanism is in use. As well as thetongue scrubber 18, a rubber handle grip may also be incorporated into the surface of thetoothbrush handle 5 for extra grip while in use. -
FIG. 35 shows a top view ofFIG. 34 , shown also is the underside of thebrush head 2 which is thecog teeth 10 and theinverted cog teeth 6 in thetoothbrush head 1. The teeth of thecog 10 andinverted cog 6 may consist of various different formations, shapes and sizes which will affect the movement and motion pattern of the cog mechanism. -
FIG. 36 shows a similar assembly to the one inFIG. 34 , the difference being theaperture 28 for thebristles 32 is not raised from the surface of theupper casing 27, as well as thewasher aperture 13 being built into thetoothbrush base 11. -
FIG. 37 shows an example of the toothbrush where this time there is a lockingwasher cap 29 that locks thebrush head 2 into thetoothbrush head 1; thecap 29 is locked into position by clips. -
FIG. 38 shows an exploded view of the toothbrush whereby thebrush head 2 is inserted from the underside of themain housing brush head 2 is inserted though thebristle aperture 28, thecog 10 andinverted cog aperture 6 is in position and thebrush head washer 12 fits into itsaperture 13, then the toothbrush underside casing 30 that has atongue scrubber 18 incorporated in it will be placed and locked into thetoothbrush head 1 by a series of clips or bonding compound or glue. A similar bonding method will be used forupper casing 28 in other example described. - Shown in
FIG. 39 is an illustration on a way in which aninternal washer 12 can be attached to abrush head 2 by means of alocking clip 31 which is incorporated into thebrush head guide 9, this simple attachment process can prove beneficial in the production process. -
FIG. 40 shows an embodiment of thebrush head 2 within thetoothbrush head 1, showing theguide 9 which protrudes from the underside of thecog 10, and the guide that protrudes from the invertedcog aperture guide 8 pointing in the opposite direction, these guides assists the mechanism andbrush head 2 to work in a fuller orbital movement to avoid any break in the perpetuation when used by the consumer. In this example theguides -
FIG. 41 shows side view and top view of abrush head 2 with 4 dental floss bristles 33 bits which may have rubber tips incorporated into thebristle 33; these have thinner and more square shaped ends to allow better cleaning in between gaps of the teeth, there can be more or less dental floss bristles 33 incorporated. The rubber end bits on thedental floss 33 bristles allows tension, and more grip against the teeth thus assisting the brush head and mechanism to move and work easier. -
FIG. 42 illustrates a side view and top view of abrush head 2 withangled bristles 34 andvertical bristles 32. The angled bristles 34 are rooted around the outer side of thebrush head 2, these angled bristles are angled towards the centre of the brush head, this will allow a push or tension against the teeth while in use thus to allow the mechanism andbrush head 2 to move and function better. There are fourangled bristles 34 equally space around the outer ring of thebrush head 2, there may be more of thesebristles 34 incorporated. The edges of the angled bristles 34 are also flat in this example. Othervertical bristles 32 andangled bristles 34 may also have rubber edged ends to allow more grip against teeth to assistbrush head 2 and the mechanism movement. -
FIGS. 43A and 43B shows a example ofangled bristles 34 similar to those inFIG. 42 , the difference being the ends of the angle bristles 34 have a sharp edge rather than a flat edge allowing the edges to help clean between the gaps of teeth and allowing tension against the teeth. -
FIG. 44A shows a side view of a variation of thebrush head 2 inFIG. 43 , andFIG. 44B shows a top view. Thebrush head cog 10 part is angled along with the angled bristles 34, this allows the force applied to thebrush head 2 when come in contact against the consumer's teeth to be focused down and outward to help push thebrush head 2 sideward and thus in a rotating and orbital motion as the mechanism engages.FIG. 44B shows there can be more than fourangled bristles 34 equally separated. -
FIG. 46A shows a side view ofangled bristles 34 that cross each other, the twoangled bristles 34 on the outer circle are angled towards each other, the correlatingangled bristles 34 on the inner circle are paired and move away from each other, each bristle from each pair will also have a bristle from another pair angling towards each other, this pattern is consistent and applies throughout the inner circle of thebrush head 2, the same can be done for the outer circle.FIG. 46B illustrates the pairing, where on the outer circle the shaded bristle is the right hand angled bristle and the non-shaded is the left hand angled bristle, the gap in-between the shaded and non-shaded can be filled with a normal vertical bristle 32, or the angled bristles 34 can be paired more closer to pack more angled pairs of angle bristles 34 in. On the inner circle the shaded is the left angled bristle and the non-shaded is the right hand angled bristle. The angled bristles, vertical bristles and rubber incorporated bristles may be included and set in different patterns and formation to allow thebrush head 2 to offer various cleaning sensations of the teeth. These various bristle designs and formations may be incorporated in all the designs described. -
FIGS. 46C and 46D shows gap fill bristles 35, these fill in the gaps created by the angled bristles 34, and these may or may not be included. -
FIGS. 47A to 47C illustrate a different formation ofangled bristles 34 incorporated into thebrush head 2, the angled bristles 34 on the outer circle angle towards the centre of thebrush head 2, and the angled brush heads on the inner circle of the brush head are angled away from the centre of thebrush head 2, theseangled bristles 34 run through the entire circumference of the outer and inner circle of thebrush head 2. This particular formation encourages brush head movement by having directional push when the angled bristles 34 make contact with the consumer's teeth. The angled bristles 34 may also be sharp edged like depicted inFIG. 43B .FIGS. 47B and 47C show the gap fill bristles 35 are rooted where there is a gap formed due to the angled bristle 34 positioning. -
FIG. 48 shows an angled bristle 34 that is surrounded at the root by a rubber socket 36 which gives the bristle 34 more strength and support giving it added tension, the same applies for the vertical bristle 32. -
FIG. 49A is a side view of thebrush head 2 withfriction reducing bits 37, andFIG. 49B is a view of the underside of thebrush head 2. Thefriction reducing bits 37 are shaped as semi globe shapes, the end of thesemi globe bit 37 will have less surface area in contact with the base of theinverted cog aperture 6 thus allowing less friction when in motion. Theinverted cog aperture 6 base will consist of a smooth flat surface that may include a shiny smooth texture to allow less friction as the reducingfriction bits 37 from the underside of thebrush head 2 skate across the surface, this may apply to all examples described. -
FIG. 50 illustrates a side view of thebrush head 2 withfriction reducing bits 37 in the shape of indentations bits that are inverted semi globe shapes, cylinder holes or notches on the underside of thecog 10 base that creates an air cushion against the flat smooth surface of theinverted cog aperture 6 base when thecog 10 andbrush head 2 is in use. -
FIG. 51 depicts the different types of textured surface that can be applied to help reduce friction of the underside of thecog 10 base when in contact with theinverted cog aperture 6 base; these examples show a crossing grid texture and lines texture to reduce friction between the smooth flat surface of thecog aperture 6. -
FIG. 53 shows to the left the underside of afriction reducing rim 38 and to the right a 3D embodiment of thebrush head 2, the rim exerts less friction on theinverted cog aperture 6 base, as well as generating a cushion of air when the toothbrush is in use.FIG. 54 shows a similar example but with aguide 9 incorporated on the underside of thecog 10 base, theguide 9 is a semi globe shape or a cylinder shape.FIG. 55 shows an embodiment of theguide 9 and guide 8 protruding from theinverted cog aperture 6 base ortoothbrush base 11. -
FIG. 56 shows an underside view of thebrush head 2 with semi globe shaped or cylinder shapedfriction reducing bits 37 including theguide 9,FIG. 57 shows a similar embodiment but without theguide 9. -
FIG. 58 is an illustration of thetoothbrush head 1 with theinverted cog aperture 6 that is moulded into thetoothbrush base 11 which includes the reducingfriction bits 37, thus thecog 10 base will be flat and smooth in this instance, this method can also be used with the other forms offriction reducing bits 37 andrim 38, and guides 9,8. -
FIG. 59 shows a friction reducingball ring 39 which is placed in between thecog 10 base and theinverted cog aperture 6 base instead of using thefriction reducing bits 37. -

FIGS. 69 to 69G shows a side view of the circular brush heads 2 that are formed of different shaped bristles, these different shapes alter the cleaning sensation the brush head bristles 32 will have on the consumers' teeth.FIG. 69D has wave or ripple shaped surface made up from bristles 32.FIG. 69E shows angled bristles with a centre cluster of bristles that expand outwards as they get further from the base.FIG. 69F depicts abrush head 2 with stiffer bristles and smoother tip ends so the contact is not to harsh on the consumers' teeth, yet still having enough tension between thebrush head 2 and the consumers' teeth to allow or force the cog mechanism to drive.FIG. 69G shows abrush head 2 withangled bristles 34 that are angled towards the centre of thebrush head 2; thebristles normal bristles 32 and rubber incorporated or rubber dental floss bristles 33 or even the rubber bristle socket 36 allowing for a more stiffer bristle. -
FIG. 70 shows a top view of a cog mechanism that consists of a four cog system. Thebrush head cog 10 is hollow inside and is similar to thering cog 42 in its functionality, the hollowbrush head cog 10 which has teeth running on the inner side only is placed over a small cog or driveshaft cog 40, thedrive shaft cog 40 is part of thering housing cog 42, and are treated as one piece. Thering housing cog 42 has a smooth inner wall similar to the outer wall of thebrush head cog 10. As the brush head moves in a circular motion thebrush head cog 10 pushes against thering cog 42, which in turn engages thering cog 42 with theouter cog aperture 6, as all cogs are engaged and work together thedrive shaft cog 40 also rotates and helps drive thebrush head cog 10 to rotate. -
FIG. 71 shows an exploded side view of the various components of the cog system depicted inFIG. 70 . -
FIG. 72 shows a similar mechanism to the one described inFIG. 70 , however the difference being both inner wall of thering housing cog 42 and outer wall of thebrush head cog 10 have teeth, therefore the driving mechanism consisting of a six cog system. - The cog mechanism in
FIG. 73 is similar to the one described inFIG. 70 , the difference being theouter cog aperture 6 being oblong or elongated in shape. The same applies for the cog configuration used inFIG. 72 that may also be used in-conjunction with anoblong cog aperture 6. -
FIG. 74 illustrates an exploded side view of thetoothbrush head 1 with the different cog components included inFIG. 72 . The way this toothbrush may be assembled is from thecog ring 42 including thedrive shaft cog 40 being placed into theouter cog aperture 6 which is moulded into thetoothbrush base 11 includinghandle 5, then the brush head andhollow cog 10 is placed over thedrive shaft cog 40 and to secure all the component parts and mechanism the toothbrushupper casing 27 is placed on top and fixed via clips or moulded by glue, heat. The upper casing also includesbristles 4.FIG. 75 illustrates thetoothbrush head 1 with all the components come together, andFIG. 76 shows thestagnant bristles 4 that may be used to cover thetoothbrush head 1, these may include other angled 33 and rubber incorporated bristles 34. -
FIG. 77 shows a 2 cog system, the hollowbrush head cog 10 placing over a circularcentral guide 9 that rotates and is held into position by means of apivot pin 41 or it is a stagnantcircular guide 9 that is moulded into thetoothbrush base 11. Thebrush head cog 10 engages with thecog aperture 6 when the toothbrush is used in a circular motion. -
FIG. 78 illustrates a stationarycentral guide 9 with thebrush head cog 10 being placed over it. -
FIG. 79 shows a four cog system, the hollowbrush head cog 10 which has cog teeth on both sides is placed over a smallcentral cog 43 that rotates and is held into position by means of apivot pin 41 shown inFIG. 80 that secures it to thetoothbrush base 11. The smallcentral cog 43 may be used as a damper component and guide 9 to assist with a smoother and more controlled action of the mechanism. The smallcentral cog 43 may also be stationary and moulded as part of thetoothbrush base 11, this will encourage and enhance movement of thebrush head cog 10 and thus thebrush head 2 itself as they both engage while the toothbrush is in use. Thebrush head cog 10 engages with thecog aperture 6 when the toothbrush is used in a circular motion. -
FIG. 81 shows a top view of a two cog system, it is similar to the cog system inFIG. 79 , the difference being instead of the outer aperture being aninverted cog 6 it comprises a circular aperture with a smooth wall around it, with the outer side of thebrush head cog 10 also being smooth. -
FIG. 82 shows a side view of abrush head 2 and the internal cog system that consists of a six cog system including a stationary or rotating smallcentral cog 43. The six cogs system will allowmore brush head 2 rotations per brushing cycle or brush strokes by the user and a smoother mechanical action. -
FIG. 83 shows a four cog system in which thebrush head cog 10 is held in place by apin 41 inserted into thetoothbrush head base 11 to allow it to pivot thus rotate. As the toothbrush is in use the bristles of thering cog 42 will push against the consumers teeth and engage the driving mechanism, engaging and running its outer side teeth with the invertedouter cog 6, and with the inner cog teeth of thering cog 42 engaging against thebrush head cog 10, thus allowing thering cog 42 and corresponding bristles to move in an orbiting like movement, and thebrush head cog 6 andbrush head 2 to rotate. The cog mechanism may also be adapted to work so that thebrush head cog 10 does not move and is affixed to thetoothbrush base 11, where thecog ring 42 still is able to move. Thebrush head cog 10 may also be free moving and not affixed to thetoothbrush head base 1, meaning the outerinverted cog 6 may be included as elongated or oblong in shape. These modifications may be applied to cog systems illustrated and used inFIGS. 84 to 91 . -
FIG. 84 shows a side view of thetoothbrush head 1. In this example the middle cog is aring housing cog 42 that has a hole in the middle to allow thepivot pin 41 of thebrush head 2 to connect through to thetoothbrush head base 11. The cog mechanism inFIG. 83 may also be adapted to work so that thebrush head cog 10 doesn't move and is affixed to thetoothbrush base 11, and the only moving part therefore being thering housing cog 42 and its brush head bristles 32. -
FIG. 85 is a top external view of thetoothbrush head 1 shown inFIG. 84 with the brush head bristles 32, toothbrush head bristles 4 and handle 5 connected. -
FIG. 86 shows an exploded view of a toothbrush, shown is atoothbrush base 11 withbrush head 2 which is affixed by apivot pin 41, over the brush head goes thering cog 42 and over both is placed the toothbrush head cover oruppercasing 27 which includes theouter cog 6. This toothbrush functions in the same way as the toothbrush shown inFIG. 84 .FIG. 87 illustrates a side view of the toothbrush in its assembled form. - A variation of the toothbrush in
FIG. 86 is whereby thebrush head 2 is free moving and without a connectingpivot pin 41, thebrush head cog 10 is housed between thering cog 42 and thetoothbrush base 11, and in-turn bothcogs upper casing 27, as the brush head bristles 32 make contact against the consumer's teeth the cog mechanism initiates and all three cogs work together to rotate and move thecog ring 42 andbrush head cog 10 while the toothbrush is used in a circular motion. -
FIG. 88 show top view of an internal cog system whereby thebrush head cog 10 rotates via apivot pin 41 or axle and the surroundingcog ring 42 moves in an orbital motion, the inner side of thecog ring 42 has teeth and the outer side is smooth, theaperture 6 wall that surrounds the cogs ring 42 is smooth and is incorporated into thetoothbrush head uppercasing 27. When the mechanism is engaged and moving thering cog 42 will move in an orbiting movement and the outer wall will touch the wall of theaperture 6, as thering cog 42 moves, its inner teeth engage with thebrush head cog 10 and thebrush head 2 rotates. Another version would be where thebrush head 2 andcog 10 would not rotate and be set in as part of thetoothbrush head base 11, and the only moving part would be thering cog 42 and the associated brush head bristles 32. -
FIG. 89 shows the external top view of thetoothbrush head 1 that belongs to the internal mechanism shown inFIG. 88 . Thebrush head 2 is covered withbristles 4, and thering cog 42 is also covered with brush head bristles 32. The internal side view is similar to that depicted inFIG. 87 . This toothbrush works in the same way as the one depicted inFIG. 87 , the difference is it uses a two cog system -
FIG. 90 shows an exploded side view of anelongated toothbrush head 1 that is similar to the conventional manual toothbrush heads, included is the cog mechanism shown inFIGS. 88 , 89. The cog mechanism inFIGS. 83 , 84 and 86 may also be used with this elongated design.FIG. 91 shows a top external view of thetoothbrush head 1 with the surroundingbristles 4 that mimic a typical manual toothbrush shape.FIG. 90A illustrates asimilar toothbrush head 1 depicted inFIG. 90 andFIG. 86 , the difference being the aperture orcog aperture 6 is moulded into, and part of the actualtoothbrush head base 11 instead of theuppercasing 27; this may be incorporated similarly in other examples of toothbrushes described. -
FIG. 92 shows an internal cog mechanism which consists of thebrush head cog 10 which is affixed by apivot pin 41; thering cog 42 surrounding thebrush head cog 10 has the same amount of teeth as the farouter cog 6 that is part of theouter casing 27. When the toothbrush is in use and the cog mechanism is in motion the teeth of thering cog 42 push against the teeth of the outerinverted cog 6 and this in turn allows movement, that engages the teeth of thering cog 42 with the teeth of thebrush head cog 10, and the interaction of the cogs encourages thebrush head 2 to rotate. A variation of this cog mechanism is where thebrush head cog 10 is not secured by apivot pin 41 and is free to interact with thering cog 42, to move and rotate freely. -
FIG. 93 shows a top external view of thetoothbrush head 1, shown are the brush head bristles 32 incorporated into thering cog 42 that make contact against the users' teeth and allow the cog system to initiate. -
FIG. 94 shows an exploded side view of the cog mechanism depicted inFIG. 92 but this time it's placed within anelongated toothbrush head 1.FIG. 95 shows an external top view of thetoothbrush head 1 inFIG. 94 . -
FIG. 96 shows a side view of an internal cog system similar to the one show inFIG. 94 , the difference being thebrush head cog 10 is slotted into a cylindrical aperture within thetoothbrush head base 11, which houses thebrush head 10 instead of having to use thepivot pin 41. As the toothbrush is in use the consumer's teeth will brush against thebristles 32 incorporated intocog ring 42 and in-turn this will engage thebrush head cog 10 to rotate thebrush head 2. -
FIG. 97 shows a side view of an internal cog system similar to the one show inFIG. 94 , the difference being nopivot pin 41 is needed, thebrush head 10 is slotted into position from the underside of thetoothbrush head 1, and thebrush head 10 has awasher 12 or rim to secure it in its housing, with a cap orunderside cover 30 that fits into the underside of thetoothbrush head base 11. -
FIG. 98 shows a cone with a round sphere connecting bit that is one piece and fits into a sphere aperture in the underside of thebrush head cog 10, the cone part fits into a cone like aperture in thetoothbrush base 11, this allows thebrush head 2 to be directed into the edge wall of theinverted cog aperture 6 without having to tilt.FIG. 98A shows a similar cone shape but this time the sphere connecting bit is also a cone.FIGS. 98B to 98O are also various brush heads with additional component parts to assist with movement when the toothbrush is in use. The different shapedinternal cog 10 andcog aperture 6 parts and components are incorporated to help thecog 10 to rotate or move more easily, creating less friction and a more centred point of gravity. Some of the internal cog systems mainlyFIGS. 98H to 98J will tilt towards the outer wall of theaperture cog 6 and thus encourage or force thebrush head cog 10 teeth to engage against the teeth of thecog aperture 6. These brush head components will be typically used for the two cog system. -
FIG. 99 is a diagram of the internal mechanics of abrush head 2 with acone shape guide 9 protruding from the underside of thebrush head cog 10, and anothercone shape guide 8 protruding from the centre of thetoothbrush head base 11, pointing in the opposite direction. The guides help thebrush head cog 10 teeth to be forced against the outerinverted cog 6 teeth when in motion. -
FIG. 100 shows a top view of a two cogmechanism toothbrush head 1. -
FIG. 101 illustrates an internal top view andFIG. 102 shows an internal side view of a mechanism including a cone shape bit that helps concentrate the centre of gravity to allow thebrush head 2 to tilt when in use. -
FIG. 103 shows abrush head 2 with thebristles 32 being partially covered in a rubber sleeve 36 or sock 36 to keep thebristles 32 stiffer or more firm, these may be incorporated into all the brush heads 2, 42 mentioned as well as into thetoothbrush head 1 itself. These rubber sleeved bristles 36 assist in creating a more firmer or stronger contact force with the consumers' teeth thus creating more force to run the mechanical cog systems. Other rubber dental floss type bristles may also be used. -
FIG. 103 shows a two cog system that uses different shaped teeth/bits, these teeth can generally be of different shapes and sizes providing they create a suitable contact with each other that allows the cog mechanism to engage and function, this applies to all the cogs and cog systems described. As well as the use of cog teeth, abrasive surfaces can also create friction and act as cog teeth and therefore, may be incorporated instead of cog teeth in the examples of the described rotating cog systems. -
FIG. 105 illustrates a side view of thebrush head 2 and cog mechanism, where the brushhead rim cog 45 is ring shaped with ridges running around it on the underside of thebrush head 2. Similarly there is arim cog 45 opposite to the accompanying ridges which are embedded into thering housing cog 42, which the brushhead rim cog 45 fits into, these in turn are housed within theinverted cog aperture 6, which has teeth that connect with the teeth of the outer wall of thering housing cog 42 as the toothbrush is in use.FIG. 107 is an aerial illustration of arim cog 45, the ridges or teeth may be spaced closer or further from each other. -
FIG. 106 shows an internal side view of a brush head where the cog is on the under side and the engaging cog opposite it is incorporated into thetoothbrush head base 11. The tip of the triangle shape on the underside of thebrush head 2 fits into a notch that is moulded into thetoothbrush base 11, this raises the brush head slightly to allow a tilting effect and to pin point the centre of gravity to influence thebrush head 2 to tilt a particular way when in use. -
FIG. 107 illustrates the cog rim 45 that may be incorporated into the underside of thebrush head 2,toothbrush head base 11, and ringhousing cog 42. -
FIG. 108 shows a variation of thebrush head 2 inFIG. 106 , which includes a ball moulded into the brush head base or loosely place in-between the 2 cog parts. -
FIG. 109 shows abrush head 2 with the rim cogs 45 both on top and bottom of thebrush head 2 and the opposite rim cogs incorporated into thetoothbrush head base 11 anduppercasing 27 or cover. The rod also attached to thebrush head 2 will allow thebrush head 2 to be raised to pin point the centre of gravity and influence a tilt effect when in use. -
FIG. 110 shows abrush head 2 with a cone shape likecog 10 on the underside and its invertedopposite cog 6 incorporated into the base. -
FIG. 111 depicts an aerial view of the cone shapedcog 10, or inverted cone shapedcog 6. -
FIG. 112 shows examples of the different textures that can be used instead of cog teeth which allow friction and thus move the brush head when in use. The left side of the illustration is the equivalent to therim cog 45, and the right side shows the equivalent to the cone shapedcog 10. -
FIG. 113 illustrates abrush head 2 and theround sphere cog 10 that is inserted into thesphere cog aperture 6 that's incorporated into thetoothbrush base 11. Thesphere cog 10 has ridges running around it and the corresponding invertedsphere cog aperture 6 also has accompanying ridges or teeth that engage together when the mechanism is in use. -
FIG. 114 shows a similar version ofFIG. 113 , with an addition of a cone like guide protruding from thetoothbrush base 11, and the corresponding brush head cone shape aperture. The cone and cone aperture has ridges running top to bottom, these act like thecog 10 andcog aperture 6. -
FIGS. 115 to 117 depict different versions ofcog apertures 6 andcogs 10, both have the same amount of teeth or arms and are sized to restrict any rotational movement; the different shaped cog teeth or arms are formed to allow thebrush head 2 to move in a oscillating like movement, as thebrush head 2 moves to the outer edges, thecog teeth 10 and thus thebrush head 2 moves in-relation to the accompanying shapes of theinverted cog teeth 6. -
FIG. 118 shows abrush head 2 and mechanism that is similar to thebrush head 2 depicted inFIG. 116 , the difference being the cog teeth or ridges are angled in a different direction, and there are incorporatedcog 6 andinverted cog 10 to the sides, this may be included or excluded, the same may be applied to thebrush head 2 depicted inFIG. 116 . -
FIGS. 119 to 122 illustrate internal side views ofvarious brush head 2 and internal cog systems. These cog systems are similar in configuration to the systems previously described, the difference being the cogs have been modified in size or insertion ordering to allow the cog system including brush heads 2,cogs toothbrush underside casing 30. Other cog systems and mechanism described may also be modified in a similar way to allow for the component parts of the cog system to be inserted from thetoothbrush head 1 underside. - The
FIG. 122 cog mechanism may also be configured so it includes acentral cog 43 similar to the one shown inFIG. 121 meaning thebrush head cog 10 will have include an inner inverted cog to accommodate the smallcentral cog 43, the outer wall of thebrush head cog 10 will be smooth and free of any cog teeth, likewise the inner and outer walls of thering cog 42 and wall of thecog aperture 6. Thering cog 42 acts simply as a facilitator to drive thebrush head cog 6 andcentral cog shaft 43 mechanism as the user's teeth engage with its bristles. -
FIG. 123 shows an internal side view of abrush head 2 with awasher 12 splitting top and bottom part of thecog 10. Thewasher 12 also locks and helps hold thecog 10 in place while the cog mechanism is engaged, this lockingwasher 12 may also be incorporated into particular cog systems described. -
FIG. 124 shows a side internal view of the two cog system depicted inFIG. 61 , shown is abrush head cog 10 that is inserted into the toothbrush headmain base 11 from underneath, and theinverted cog aperture 6 which is oblong in shape is incorporated into theunderside casing 30.FIG. 125 shows the oblong shape orbital tract 7 that thebrush head 2 will move in due to the shape of theinverted cog 6, this oblong shape will mimic the similar movement the consumer will naturally use for brushing their teeth. -
FIG. 126 illustrates an internal side view of the vibrating mechanical toothbrush, included is themechanical toothbrush head 1 part and thehandle 5 part that includes thebattery 52, and aelectric motor 46 with an offsetweight 48 attached to the axel which are encased within theelectrical motor housing 47. There areelectric wires 49 both positive and negative that are connected to the associatedwire contacts 50, one wire is connected to theswitch 51 and the associatedwire 49 to thebattery 52contact bit 50, the other wire connects to a battery hinged cap that makes contact with the battery. Thehandle housing cap 54 seals and closed the toothbrush housing. As the consumer uses the toothbrush in a circular like movement thecog mechanism brush head 2 will rotated or move, in addition to thebrush head 2 moving, the On/Off switch 51 may be pressed to engage the electrical motor making thecounter weight 48 spin and thus making thetoothbrush head 1 vibrate. -
FIG. 127 shows a similar toothbrush to the one inFIG. 126 , with thetoothbrush head 1 this time being able to be detached and re-attached, or replaced. Themale handle part 16 has a lockingnotch 17 which inserts and locks into the femaletoothbrush head part 15; this also has a corresponding locking part. -
FIG. 128 depicts an external side view of the toothbrush shown inFIG. 126 . -
FIG. 129 shows a front external view of the vibrating mechanical toothbrush inFIG. 128 . -
FIG. 130 shows an internal side view of a variation of the toothbrush inFIG. 126 , wherein the switch has a separate on/off part and a metal clip contact bit that is shaped and behaves in accordance to which switch button is pressed. When the top switch button is pressed the clip is arched with its edge pointing down, as the edge points down the switch contact clip 55 makes contact ametal contact part 50 the is linked to the motor via awire 49, the other side to the clip is always in contact with thebattery 52. Also depicted to the bottom of the diagram is a hatch or door is used to secure the battery in the main handle housing and also act as a contact bit. -
FIGS. 131 to 133 illustrate the rechargeable vibrating mechanical toothbrush, which is seated in itscharger 56. The charger orinduction charger 56 has a primary coil 57 in the base and has aniron peg 59 running through, the base of thetoothbrush handle 5 has also asecondary coil 58 within and this is placed over thepeg 59, thispeg 59 also secures the toothbrush to the charger base. Thepeg 59 acts as the core linking the primary 57 andsecondary coils 58 electromagnetically, when both coils 57, 58 come together a complete transformer is realised that works by electromagnetic induction, whereby the energy flows from the coil 57 in the charger to thecoil 58 in the toothbrush handle 5 base though thepeg 59. Thecoil 58 in the toothbrush base is connected to thecircuit board 61, and therechargeable battery 52 is connected to both ends of thecircuit board 61, the circuit connection from the negative side of thebattery 52 runs all the way to the other end and connects to the vibratingmotor 46 via thecontact bit 50. Themotor 46 is contained in itmetal housing 47 that is also connected to the metal male handlepart 16. The positive end on thebattery 52 is connected to the other end of thecircuit board 61 and the electrical current is controlled via an on/offswitch 51. The charger is connected to the mains via an electrical cord 62, as the charger is powered on, and the toothbrush placed over theiron peg 59 that is covered in plastic a charginglight indicator light 63 also illuminates, the chargingindicator light 63 is also shown in the external illustration inFIG. 131 . Themechanical toothbrush head 1 that contains the mechanical cog system andbrush head 2 that is detachable. Themale handle part 16 has a lockingnotch 17 which inserts and locks into the femaletoothbrush head part 15; this also has a corresponding locking part. As the toothbrush is operated themotor 46 rotates the offsetweight 48 connected to themotor 46 via an axel or shaft, causing thetoothbrush head 1,brush head 2 and bristles to vibrate and pulse. A silicon chip and processor may also be incorporated within the toothbrush to include an electric timer. - All components described above may be interchanged with one another and used in various configurations.
- The vibrating mechanical toothbrush is made from plastic, rubber, metal material, magnet, bristle fibres, Nylon, or from a combination of these materials.
- The vibrating mechanical toothbrush is either moulded or/and glued together or adjoined by a series of small male and female clips or a combination of these methods. There may also be other locking methods used, including all or combinations of a series of clips, glue, pins, screw threading around toothbrush casing or covers 27, 30 or heat moulding techniques. This
detachable toothbrush head 1 system can be applied to all described above. - All designs shown above can have one or more brush heads 2; the
toothbrush head 1 may or may not includebristles 4, thehandles 5 can be detachable or non-detachable. - The
cog 10 andinverted cog 6 teeth consist of different shapes, sizes and amounts; these will affect the behaviour, motion and speed of the mechanism andbrush head 2 when engaged. - Different shaped teeth/bits can also be incorporated into the cog systems, these teeth can generally be of different shapes and sizes providing they create a suitable contact with each other that allows the cog mechanism to engage and function, this applies to all the cogs and cog systems described. Rubber may also be incorporated into the cog teeth to allow grip between teeth, a softer and smoother mechanical action. As well as the use of cog teeth, abrasive surfaces can also create friction and act as cog teeth and therefore, may be incorporated instead of cog teeth in the examples of the described rotating cog systems.
- The
cog 10,ring cog 42 andcog aperture 6 can also consist of different shapes and sizes; this will also affect the behaviour, motion and speed of the mechanism andbrush head 2 when engaged. The eye or oblong shape invertedcog aperture 6 may be incorporated into the various cog systems where thebrush head cog 10 is free to move and not affixed by a pin orother guide ring housing cogs 42 within a cog system, for example aring cog 42 within aring cog 42, this will affect the speed and movement of the brush head. -
FIGS. 134 and 135 illustrate the brushhead male cog 10 like part that sits into the femaleinverted cog 6 like aperture, with a moving telescopic movingwasher 64 interlinking with the round brush head's 2double washer ring 24. Theinternal locking washer 12 helps to secure thebrush head 2 to thetoothbrush head 1main body 11. Thewasher locking aperture 13 allows the lockingwasher 12 to move freely yet allow thebrush head 2 to still move. As thebrush head 2 moves so does the telescopic movingwasher 64 and therefore covering the internal workings of the toothbrush. -
FIG. 136 shows abrush head 2, with atelescopic washer 64 which sits on top of the brushhead top washer 3, the internal workings and mechanics are covered and locked by the series of washers that work in a telescopic fashion. -
FIG. 137 shows thebrush head 2, which is held in place by a part that acts like the lockingwasher 12 but which additionally has arms that are embodied within the maintoothbrush head base 11 and is shaped to allow toothpaste and liquid to disperse through, as the toothbrush is in use, there aredrainage holes 65 or channels within thebase 11 that also allow liquid to drain. -
FIG. 138 shows a similar mechanical system to the one shown inFIG. 137 but this time thetelescopic washer 64 is at the top surface of thetoothbrush head 1 and is held in place by clips that allow the washer to move yet lock thebrush head 2 and internal mechanics in. -
FIG. 140 depicts a side internal view of theinternal brush head 2 mechanism withfriction reducing bits 37 incorporated with thetoothbrush base 11 which may consist of a plastic bit, a series of small plastic pins, or even bristles to minimise contact with thebrush head washer 3. The double sided cog likering 42 which has contact surface on outer and inner sides also helps reduce the circular orbiting movement but yet acts like an additional gear against the other cog like means 10, 6. Also shown isdrainage hole 65 which may also be incorporated a various places of the toothbrush to reduce clogging and allow the inner parts of the devise to be cleaned.FIG. 141 shows a similar variation of thebrush head 2 mechanism, with acog ring 42 and locking means 12 from the underside of thebrush head 2, again drainage holes/channels 65 may also be incorporated in all designs described. -
FIG. 142 shows a side internal view and an embodiment of thebrush head 2mechanism washer 12 securing thebrush head 2 to thetoothbrush base 11. As thebrush head 2 makes contact with the consumers teeth or surface while thehandle 5 is moved in a circular motion thebrush head 2 rotates in an opposite direction, while it is still secured to thetoothbrush head 1 via the lockingwasher 12. -
FIG. 143 shows a similar cog system to that shown inFIG. 142 , but this time the brush head cog 10 (gear means) is hollowed out thus creating less friction with toothpaste, and more area and thus time for the toothpaste and liquid to disperse through drainage holes 65 while in use. Also included are rounded or pinpointed edges to reduce friction and minimise contact with thetoothbrush base 11. -
FIGS. 145 to 145B show the underside of some different textured friction/contact reducing bits 37 orrims 38, these may be incorporated on the bottom of thebrush head 2cogs 10 like means on all designs described, to reduce friction and clogging up and sticking of the mechanism. -
FIGS. 146 and 147 show a similar embodiment of the cog system shown inFIG. 144 , the brush head cog (gear means) consists ofmultiple arms 10 that run all the way round and reduce contact with thebase 11, the contact points 10 are pin pointed thus reducing friction, also the edges of the arms act like the male cog like 10 bits that make contact with the outer wall 6 (or female cog like means). The centre part where the arms join is hollowed out thus creating room for movement and dispersion of toothpaste and water while in use;drainage 65 may also be incorporated to help with dispersion.FIG. 146 shows thebrush head 2 which is slightly raised and offset, so the arms can paddle through the toothpaste liquid mixture if the mechanism clogs up, once thebrush head 2 is up to speed it will raise slightly like a hydrofoil and stabilise into a more harmonious brush head rotating movement, and thus thearms 10 touching theouter walls 6. -
FIGS. 149 and 149A shows a parachute or detent means of lockingwasher 12,FIG. 149 shows in a closed disposition and 149A shows it in open and thus locked disposition. -
FIGS. 150A and 151 show drainage channels 65, these may be incorporated into all designs described where appropriate. -
FIG. 153 shows a system where thecontact arms 10 curl inward and also reduce contact surface with thebase 11. Thecontact arms 10 are shaped to coincide with the recesses of the corresponding female cog likemeans 6; this also applies to allsimilar contact arm 10 designs described.

FIG. 169 illustrates a similarly raised locking means 12 to the one inFIG. 168 but in this case thebrush head 2 has a male cog like means 10 that fits into the locking means 12, and the locking means has cog likemeans 6 that work with each other to rotate thebrush head 2. The outer series of cog likemeans -
FIG. 171 andFIG. 171A show some examples of the different contact bits that may be applied to the male and female cog likemeans -
FIG. 172 shows thebrush head 2 and drivingmechanics pivot pin 41 that also raises thebrush head 2 from theinternal base 11 of thetoothbrush head 1, this locks thebrush head 2 and help reduce the system from clogging or jamming with liquids. - Although the embodiments of the invention described above all comprise toothbrushes, similar structures will be of advantage in other brushing devices, for example for polishing or scrubbing. The features above may equally well be applied to most other forms of manually employable brushing devices, provided with bristles per se, or with equivalent structures.
- For example, the above mechanisms may be applied to brushes for polishing shoes; brushes for washing and polishing cars or other vehicles; body brushes, scrubbers, exfoliators and massaging brushes; facial exfoliating brushes; shaving brushes; dishwashing brushes; scrubbing brushes for floors, walls, ovens, worktops, or the like; floor polishing brushes; and wire brushes for maintaining suede or for cleaning off rust, etc.
- It is also believed that such mechanisms would be useful in devices which might not be considered as brushes in the strict sense, but which are used with a similar motion across a surface to be acted upon, such as sanding blocks. The term “brushing device” should therefore also be understood to incorporate such analogous devices not actually comprising bristles per se.
