TOOTHBRUSH
TECHNICAL FIELD
This invention relates to a toothbrush.
More in particular, this invention relates to a toothbrush provided with a mobile bristle-holding head.
BACKGROUND ART
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.
It is also known that in order to clean the teeth thoroughly, it is necessary torealize a movement of the bristles according to the axis of the teeth and that the toothbrushes utilized today do not allow easily this movement, as it is perpendicular to the axis of the handle.
Various solutions have been proposed to overcome this drawback. For instance, a toothbrush has been proposed whose head angulation is variable and pre-determinable relatively to the axis if the handle.
A toothbrush of this type is disclosed in the Italian patent nr. 1.205.608, granted on March 23, 1989. In this toothbrush, 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 ~ G~Y3 of rises integral with the head, which engage into recesses obtained in the handle.
By this realization, 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.
This condition can respected as long as the inclination of the handle is kept constant during the cleaning operation. In fact, minor variations in the hand position suffice to change the inclination of the handle and therefore the position of the head relatively to an original position which has been considered as being the optimum one. This involves therefore continuous changes in the angulation ofsaid head. Besides, the hand-adjustment of the head involves rather delicate hygiene considerations.

2~ ~3~3 - 2a -DE-A-3 425 940 discloses a toothbrush comprising a handle, a bristle-holding head and means for engaging the head into an end of the handle consisting of a pin pressure inserted into a recess. The bristle-holding head can freely rotate around the axis of the engagement means, however its oscillating motion with respect to the plane defined by the bristle-holding head surface is limited and prevented by the surface of the handle.
DISCLOSURE OF THE INVENTION
The object of the present invention is to provide a toothbrush which allows to overcome the above-mentioned drawbacks and limitations.
According to the present invention, this and other objects are achieved by the features in the characterizing part of claim 1.
Particular embodiments of the toothbrush of the present invention are set ~lG7Lq~3 In the toothbrush of the present invention the bristle-holding head can rotate freely, both clock- and counterclockwise and oscillate at the same time on the axis of said engagement means said axis being perpendicular to the handle.
The advantages of the toothbrush of the present invention are:

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT OF THE INVENTION
Such toothbrush comprises a handle, preferably from rigid plastic material, provided with a top end (2) and a bris-tq~
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. The assembly of said head (4) with the handle top end (2) is achieved by engaging said pin (8) into a recess (6) obtained on the surface (12) of said top end (2) oriented towards said head and realized during the moulding stage of the part. Said recess (6) comprises a lead-in round hole (11 ) whose diameter is smaller than the maximum diameter of pin (8). When pin (8)is pushed into hole (11), strips (9) bend radially just enough to allow said pin to get into said recess (6). Once pin (8) has got into recess (6), strips (9) resume their starting arrangement and 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 pin (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 corresponding surface of said back (5) and said base (13) of pin (8) and said edge (7), as shown on Figs. 1, 7 and 9. The optimum amplitude of angulations a 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 of the toothbrush subject matter of this invention.
Back (5) of the bristle-holding head (5), preferably from semirigid and slightlyelastic material, as specified above, comprises, in a balanced position, a gudgeon pin (1 8) 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 pin (16) is provided separately, whose geometrical structure allows to house in the inside, with a suitable clearance, said gudgeon pin (18). Counter-gudgeon pin (16) is provided, along its internal surface and the perimeter, withstop pegs (1 5) having a triangular rectangle transversal section, as shown on Fig.
10. Said hollow counter-gudgeon 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 t3 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 theclutching 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 a 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.
While the invention has been described with reference to some preferred embodiments, it is evident that many vari-q ~3 ants and changes may be made by those expert in the art, in the light of the abovedisclosure. Therefore, this invention includes all of the alternatives and changes that fall within the spirit and the protection scope of the following claims.
