Definitions
- This invention relates to a toothbrush.
- this invention relates to a toothbrush provided with a mobile bristle-holding head.
- Toothbrushes for dental care provided with a fixed bristle-holding head aligned with the axis of the handle are known to the art and marketed.
- a toothbrush has been proposed whose head angulation is variable and pre-determinable relatively to the axis of the handle.
- a toothbrush of this type is disclosed in the Italian patent nr. 1.205.608, granted on March 23, 1989.
- the arrangement and stabilization of the handle according to various angulations relatively to the bristle-holding head is obtained by means of rises integral with the handle, radially arranged around a joint and opposing radial recesses integral with either the head back or the internal wall of a tongue substantially parallel to the back of said head and integral with same, or by means of rises Integral with the head which engage into recesses obtained in the handle.
- variable and stabilized angulations can be obtained; in particular, angulations of 22.5°, 45°, 90° and 180°.
- the angulation of the head relatively to the handle is chosen by hand-operating on same until the position is found which allows to exercise the maximum effort in the optimum direction for cleaning the teeth, i. e along their longitudinal axis.
- Object of this invention is to provide a toothbrush such as to allow to overcome the aforementioned drawbacks and limitations of toothbrushes provided with bristle-holding heads whose angulation is variable and predeterminable
- a toothbrush comprising a handle, a bristle-holding head and means for engaging the head into an end of the handle, wherein the bristle-holding head can rotate freely, both clock- and counterclockwise, oscillating at the same time on the axis of said engagement means, said axis hemo perpendicular to the handle.
- the free rotatory movement of the head allows the same to arrange automatically in the optimum position relatively to the axis of the teeth in any point of the dental arch, independently on any change in the inclination of the hand or the handle, achieving therefore a very efficacious and rapid cleaning action.
- the oscillatory movement of the head allows to obtain an easier and more efficacious touch between bristles and teeth in the internal part of the dental arch, and in particular in the part concerned by upper and lower premolars and molars.
- Fig. 1 is a schematic side view of the toothbrush subject matter of this invention, with the top end of the handle assembled to the rotating and oscillating bristle-holding head;
- Fig. 2 is a schematic side view of the too ends of the non assembled handle and bristle-holding heads:
- Fig. 3 is a schematic front view, in correspondence of the bristle side, of the toothbrush subject matter of this invention;
- Fig. 4 is a schematic front view of the upper part of the handle
- Fig. 5 is a magnified detail of the too end (A) of the handle of Fig. 2;
- Fig. 6 is a magnified detail of the engagement means (A') of the bristle-holding head of Fig. 2;
- Fig. 7 is a magnified detail of the engagement means (B) opposite to the engagement pin (B) of Fig. 1;
- Fig. 8 is a schematic view of the side opposite to the bristle site (C of Fig. 6) of the engagement pin of the rotating and oscillating head;
- Fig. 9 is a schematic view of the section of the upper part of the handle along a plane passing through the X-X line of Fig. 4;
- Figs. 10 through 13 are details of a variant of the engagement means of the bristle-head rotating and oscillating on the top end of the handle.
- Figs. 1 through 9 show a preferred embodiment of the toothbrush provided with a rotating and oscillating head, subject matter of this invention.
- Such toothbrush comprises a handle, preferably from rigid plastic material, provided with a top end ( 2 ) and a bris tle-holding head (4).
- Said head (4) comprises a back (5), preferably from semirigid and slightly elastic plastic material, in which bristles (3) are inserted.
- Said back ( 5 ) is provided, on the opposite side relatively to bristles (3) and in a position balanced and integral with said back, with a pin (8) provided with longitudinal strips (9).
- Said pin (8) provided with said strips (9) is mushroom-shaped.
- Said recess (6. comprises a lead-in round hole (11) whose diameter is smaller than the maximum diameter of pin (8).
- pin (8) is pushed into hole (11).
- strips (9) bend radially just enough to allow said pin to get into said recess (6).
- base (13) of pin (8) draws up against edge (7) of recess (6), preventing the bristle-holding head (4) from unhooking.
- the clockwise (F1) or counterclockwise (F2) free rotation is achieved by allowing a small clearance (0.2 - 0.5 mm. between the surface of recess (6) and the peripheral surface of strips (9).
- Surface (12) of the handle top end (2) is not uniformly parallel to the corresponding surface of back (5 ) , being tapered both longitudinally above and under hole (11) and transversally at both sides of hole (11).
- Such taperings together with an angulation between base (13) of pm (8) and edge (7) of recess (6), allow head (4) to oscillate freely on the rotation axis, with angulations ⁇ between said surface (12) and the correspondirig surface of said back (5) and said base (13) of pin (3 ) and said edge (7), as shown on Figs. 1, 7 and 9.
- the optimum amplitude of angulations ⁇ is 2° - 5°.
- Figr. 10 through 13 show a variant of the system of assembly of the bristle-holding head to the handle top end ot the toothbrush subject matter of this invention.
- Back (5) of the bristle-holding head (5) preferably from semirigid and slightly elastic material, as specified above, comprises, in a balanced position, a gudgeon pm (18) provided, along the perimeter, with a rise (17) having a triangular transversal section, as shown on Fig. 12.
- the handle top end (2) preferably from rigid plastic material, as specified above, comprises a hole (21) and a recess (19), as shown on Fig. 11.
- a hollow counter-gudgeon pm (16) is provided separately, whose geometrical structure allows to house in the inside, with a suitable clearance, said gudgeon pin (18).
- Counter-gudgeon pm (16) is provided, along its internal surface and the perimeter, with stop pegs (15) having a triangular rectangle transversal section, as shown on Fig. 10.
- Said hollow countergudgeon pin (16) is suitably made from rigid plastic material, just as the handle.
- the assembly of head (5) on the handle top end (12) is obtained by introducing, in the direction of arrow F6. gudgeon pin (18) into hole (21), and introducing then in the opposite direction according to arrow F5, counter-gudgeon pin (16) into recess (19). In so doing. gudgeon pin (18) gets into the recess of said hollow counter-gudgeon pin (16), as shown on Fig. 13.
- the locking between gudgeon pin (18) and counter-gudgeon pin (16) is obtained by the clutching of said rise (17) on pegs (15).
- the rotatory movement of the head is ensured by leaving, also in this case, a clearance of 0.2 - 0.5 mm between the external surface of the counter-gudgeon pin (16) and the surface of the hole (21) and between the internal surface (14') of head (14) of said counter-gudgeon pin (16) and the surface (20) of said recess (19).
- the oscillatory movement of the head is allowed, instead, by the angulations ⁇ of 2° - 5° provided between said surface (14') and said surface (20), and, just as in the above described solution, between the taperings of surface (12) of handle top end (2) and the corresponding surface of back (5) of the bristle-holding head.
- the described toothbrush may be realized in different sizes and in particular in the sizes suitables for grown-ups and children. All the corners and tips of the head and the handle are suitably rounded off and. besides, the head protrudes relatively to the handle top.
