Description
- This application claims priority from provisional patent application No. 60/617,596.
- Not applicable.
- 1. Field of Invention
- This application claims priority from provisional patent application No. 60/617,596. The present invention relates to the field of toothbrushes.
- 2. Description of Prior Art
- There are a variety of toothbrushes on the market. In the realm of toothbrushes, the consuming public is constantly looking for a product that gives the user multiple choices for the methodology of cleaning his or her teeth. For example, for medical reasons or for reasons of simple preference, there are a variety of bristle strengths, namely, soft, medium, and firm. Some users prefer rotating mechanized toothbrushes, while others prefer a vibrating bristle, and still others prefer a hand-held manual model. Some individuals prefer a flexible hand-held toothbrush and others may prefer a rigid model. U.S. Pat. No. 5,898,967 to Wu (1999) discloses a toothbrush with a flexible head by virtue of an embedded leaf-spring in a toothbrush. It is generally accepted that a flexible head feature may be beneficial on a toothbrush, for purposes of reaching multiple tooth surfaces within the mouth and because a flexible toothbrush allows for soft tension on a gumline. U.S. Pat. No. RE38,521 to Halm (2004) features a toothbrush with a highly flexible toothbrush head member featuring elastomeric grooves between linked segments of the toothbrush head. Similar patents for toothbrushes include U.S. Pat. No. 6,708,364 to Huber (2004) (flexible head design disclosed); U.S. Pat. No. 6,219,874 to Gelder (2001) (flexible bristle-bearing head); U.S. Pat. No. 2,438,268 to Bressler (1946)(flexible head toothbrush). The Reach® brand toothbrushes have also capitalized on toothbrushes featuring angled heads, as found in U.S. Pat. No. 4,829,621 to Phenegar (1989) which has a thermoplastic elastomeric deformable neck).
- While the above referenced patents demonstrate that flexible head toothbrushes are beneficial, it is also desirable at times to have a toothbrush with a firm disposition, particularly where a deep, aggressive brush and maximal leverage are desired. Sometimes, a rigid toothbrush and head work best for maximal plaque removal. Although numerous improvements have been made in the toothbrush industry, none effectively solve the problem addressed by the present invention.
- The present invention offers an alternative to the consuming public—a toothbrush featuring choices for the user between a flexible and firm toothbrush.
- Accordingly, it is the objective of the present invention to provide an adjustable toothbrush that features either a flexible or rigid position depending on user preference.
- It is a further object of the present invention to provide a toothbrush head that will be readily adjustable between varying flexible and rigid positions.
- It is a further object of the present invention to provide a toothbrush that will be readily adjustable by means of a selectively positionable rod disposed within an internal passageway of the toothbrush.
- It is a further object of the present invention to provide a toothbrush that will be readily adjustable by means of a selectively positionable sleeve or support member disposed on the exterior of the toothbrush.
- It is a further object of the present invention to provide a toothbrush featuring a polishing feature on the backside of the toothbrush head.
- It is still a further object of the present invention to provide a toothbrush that is relatively inexpensive and yet durable.
- Other objectives of the invention will become apparent to those skilled in the art once the invention has been shown and described.
- The manner in which these objectives and other desirable characteristics can be obtained is explained in the following description and attached drawings in which:
-
FIG. 1 is a top perspective view of the underside of the multi-purpose adjustable toothbrush. -
FIG. 2 is a side perspective view of the multi-purpose adjustable toothbrush in rigid form. -
FIG. 3 is a side perspective view of the multi-purpose adjustable toothbrush in flexible form. -
FIG. 4 is a side cross-sectional view of the multi-purpose adjustable toothbrush in rigid form, wherein a thumb mount, internal passageway, and rod are depicted. -
FIG. 5 is a side cross-sectional view of the multi-purpose adjustable toothbrush in flexible form, wherein a thumb mount, internal passageway, and rod are depicted. - It is to be noted, however, that the appended drawings illustrate only typical embodiments of this invention and are therefore not to be considered limiting of its scope, for the invention may admit to other equally effective embodiments.
- Although specific embodiments of the invention will now be described, it should be understood that these embodiments are examples only and merely illustrate a small number of the many possible specific embodiments that can represent application of the principles of the invention. Various changes and modifications obvious to one skilled in the art, to which the present invention pertains, are deemed to be within the spirit, scope and contemplation of the present invention as further defined in the claims.
-
FIG. 1 is a top perspective view of the underside of the multi-purposeadjustable toothbrush 1. Specifically featured are ahandle 5,neck 6, the head 7 (one side featuring a bristle base), and thebristles 2 that are found on most toothbrushes. These components may be fashioned from materials that are known in the art. Also shown is athumb mount 3, presented in a preferable forward position, as it would preferably appear when thetoothbrush 1 is fixed in a rigid position. Thethumb mount 3 is selectively positionable by the user to control whethertoothbrush 1 and thehead 7 are in a flexible or rigid state.Thumb mount 3 may be formed from a variety of materials, including hard or soft rubbers or plastics and may be located preferably along the length of thehandle 5 or on theneck 6 for ease of use. As further described herein, thethumb mount 3 is fixedly connected to a proximal portion of arod 11 disposed within aninternal passageway 12 of the toothbrush 1 (seeFIG. 4-5 ). A change in position of thethumb mount 3 causes a corresponding change in the position of therod 11, which ultimately effects the rigid or flexible state oftoothbrush 1. The term “thumb” is not intended to limit operation of the mechanism by a thumb, however, merely describes a preferable digit employed to operate the mechanism acting on therod 11. -
FIG. 2 is a side perspective view of the multi-purpose adjustable toothbrush in rigid form.FIG. 2 shows thethumb mount 3 in a forward position and the corresponding preferable position oftoothbrush 1 and head 7 in a rigid state, which the user may prefer when maximal leverage and strength are needed during brushing. -
FIG. 3 is also a side perspective view of the multi-purposeadjustable toothbrush 1, however, in a flexible form. Thethumb mount 3 is in a downward position, which is a preferable position to allowhead 7 to bend by and through ahead flexor 9 portion of thehead 7. Sometimes it is desirable when brushing one's teeth to use a flexible toothbrush-such flexibility permitting better access to recesses, rearward teeth, or otherwise hard-to-reach surfaces. As further described inFIGS. 4-5 , this flexibility is accomplished according to user preferences when action onthumb mount 3 works to causerod 11 withininternal passageway 11 to retract from thehead 7 portion of thetoothbrush 1, allowinghead 7 to react to brushing in a flexible manner. The flexible action may be confined to a tip ofhead 7 by and through ahead flexor 9, or therod 11 may also retract to permit flexible action of theentire head 7 of thetoothbrush 1. It should be noted that this inventive feature will work with toothbrushes featuring an angled “neck” portion leading toward thehead 7 or with toothbrushes featuring contoured handles 5. -
FIG. 4 is a side cross-sectional view of the multi-purposeadjustable toothbrush 1 in rigid form, wherein thethumb mount 3,internal passageway 12, androd 11 are depicted. This view shows a preferable embodiment wherein therod 11 is pushed all the way forward intodistal passageway 13, thereby providing a rigid structure forhead 7.Thumb mount 3 is fixedly connected to a proximal portion ofrod 11, whichrod 11 then moves forward or backward withininternal passageway 12, according to the user's preference for flexibility or rigidity.Internal passageway 12 is preferably formed by injection molding, thermoform, or other molding processes, however, by any means of forming theinternal passageway 12, the principal feature of saidinternal passageway 12 is to provide a rigid and defined channel by and through whichrod 11 may pass to regulate the flexibility or rigidity of thetoothbrush 1.Internal passageway 12 extends through and within thetoothbrush 1, preferably throughhead 7,neck 6, and it may extend throughhandle 5, until such point as it preferably opens to meetthumb mount 3. Theinternal passageway 12 is of a length preferably in the range of 2 to 10 centimeters in length. Therod 11 is preferably formed from rigid plastics or metals, as its principal function is to provide rigidity when engaged.Toothbrush 1 and its components are preferably formed from materials or combinations of materials commonly known in the art of toothbrush manufacture, including but not limited to rigid plastics (polyethylenes, high density polyethlenes, polypropylenes, polyamides, elastomers, polyvinylchloride, etc.), as well as more flexible plastics, rubbers, synthetic rubbers, and elastomeric materials commonly used on handle grips to enhance flexibility on thetoothbrush 1 andhead 7. -
FIG. 5 is a side cross-sectional view of the multi-purposeadjustable toothbrush 1 in flexible form. Thethumb mount 3 androd 11 are shown retracted withininternal passageway 12, so thatdistal passageway 13 is empty, and where therod 11 is not in a position to provide rigidity to thehead 7. In other words, withoutrod 11 present in the distal portion ofpassageway 12, thetoothbrush 1 is free to respond as it otherwise might. Ahead flexor 9 is shown, which would preferably feature an elastomeric construction material to permit bending and flexibility of the toothbrush head at the toothbrush end (end opposite handle 5). The inventor contemplates thatrod 11 could preferably be withdrawn to varying degrees and in varying increments to permit varying flexibility along the entire length ofhead 7, as well asneck 6. The flexibility ofhead 7 whenrod 11 is not engaged depends solely on the construction of the head member—a variety of preferable designs and flexibilities are disclosed in the prior art. In this patent the term “thumb mount” is used to describe a preferable position for a mechanism to control movement of therod 11 withininternal passageway 12, however, the use of the term “thumb” is not intended to be limiting of the mechanism, but merely descriptive of a preferable digit likely to be used to activate the mechanism. Thethumb mount 3 could be used with an index finger, or an elbow, so long as the action is accomplished. - Although not shown in
FIGS. 1-5 , an embodiment of multi-purposeadjustable toothbrush 1 is contemplated that selectively accomplishes flexibility or rigidity oftoothbrush 1 without aninternal passageway 12 orrod 11, but rather by use of a sleeve or rigid support member slidably fixed to the back of toothbrush 1 (alonghead 7, orhead 7 andneck 6 opposite the bristle side), and wherein the toothbrusher uses his or her hands to slide the sleeve to a forward position favoring rigidity or backward to allow flexibility. Also, the inventor contemplates an embodiment of the present of the present invention where a polishing surface is on the backside ofhead 7, said polishing surface formed from synthetic rubber, textured or elastomeric plastic. - It is understood that each of the elements described above, or two or more together may also find a useful application in other types of methods differing from the type described above. While certain novel features of this invention have been shown and described, it is not intended to be limited to the details above, since it will be understood that various omissions, modifications, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing in any way from the spirit of the invention.
