Abstract
Abstract The invention relates to a toothbrush with a deflecting part (4) which has a deflection profile and is positioned between brush head (1) and stem (5) for deflecting the brush head (1) when a certain contact pressure is reach-ed. According to the invention, with a deflecting part (4) having a metallic leaf spring (6), the latter con-sists of electrogalvanized or chromium-plated steel, or of a rust proof metal or metal alloy, the leaf spring (6) being covered by a jacket (8) made of an elastomer at least on its front and back. According to the invention the deflecting part (4) is a link (7), similar to a leaf spring, which connects the brush head (1) to the stem (5) and is covered at least on its front and back by a jacket (8) made of an elastomer. The elastomer is a natural or synthetic rubber, such as styrene-butadiene rubber, butyl rubber, ethylene rubber, propylene rubber, silicone rubber, or an ethylene vinyl acetate copolymer or plasti-cized PVC.
Description
Toothbrush with a_deflecting ~art havlnq a deflection profile ; The invention relates to a toothbru~h with a deflecting part which has a deflection profile and i~ positioned S between brush head and stem, serving to deflect the brush head when a certain contact pressure is reached.
German Offenlegungsschrift 3,706,345 discloses a similar ~oothbrush for manual or mechanical operation. With this too~hbrush the brush head can be deflected on the brush stem when a certain contact pressure is reached, in such a way that an optimum contact pressure can be maintained when brushing the teeth. The deflecting part is designed similar to a leaf spring, and can be cambered or angular and have a central longitudinal slit so that, when too high a contact pressure is exceeded, the brush head can move from its previously extended position into a deflec-ted position with respect to the longitudinal axis of the stem. This gi~es a signal to the user; further brushing of the teeth would also at least be made more difficult, if not impossible. The deflection can occur more or less pro~ressively or, beyond a click point, very fast.
Due to the narrowing of the deflecting part similar to a leaf spring,the toothbrush appears to be disproportioned, and due to the spring being expesed there is a risk of injurie2 to the mouth because of the edqes, and of pinching if a longitudinal slit is present, when the toothbrush i8 used.
~he object of the invention is to specify a toothbrush with a deflecting part having a deflection profile, which toothbrush ha3 an attractively ~haped appearance without the deflecting being obstructed, and i~ free from edges pre~enting a risk of injuries and free from slits.
This object i~ achieved by a toothbrush having the feature~ of Claim 1 or Claim 2.

Advantageous embodiments of the invention can be taken from the subclaims.
The invention is explained in more detail below with the aid of exemplary embodLment~ with reference to drawings, S in which:
Figure 1 shows a plan view of a toothbru~h, Figure 2 shows a side view of the toothbru~h, Figure 3 shows a deflecting part on an enlarged scale, Figure 4 shows a design variant of a deflecting part on an enlarged scale.
A toothbrush consists of a brush head 1 with the bristle~
2 and a transi ~on part 3, a defl~cting part 4 and a stem 5. The deflecting part 4 connects the transition part.3 ; to the ~tem 5, serving as handle. The deflecting part 4 can have a metallic leaf spring 6 or a link 7 of any type of material, including plastics. Preferably, the link 7 and the leaf spring 6 are antirely enclosed by a jacket 8 made of an elaætomer, covering all sharp edges of the : leaf ~pring 6 or of the link 7. The jacket 8 made of elastomer is designed so that it forms a positive connec-tion of the free end of the tran~ition part 3 of the brush head 1 with the connecting end of the stem 5 and nevertheles~ enable~ the leaf spring 6 or ~he link 7 to be deflected. The jacket 8 can also serve the optical 2S de~ign of the toothbru~h and, for example, have a concave or convex camber and can have different colours compared with the other parts of the toothbrush.
If a metallic leaf spring 6 is used, this is preferably firmly anchored in the transition part 3 or in the ~tem . 5, for example by mean~ of the in~ection moulding pro-cedure. In this case, the jacket 8 can either have been applied previously or it can be applied subsequently,when the transition part has already been firmly connected ~y means of the leaf spring 6 to the stem 5.

: ::: . .. . . .
0;~9 In the case of the deflecting part 4 having a link 7, the bru~h head 1 can be mhde without bri~tles 2, the transi-tion part 3, the deflecting part 4 and the stem 5 can be manufactured of one material in one manufacturing step, for example by ln~ection mou:Lding. The link 7 can also be manufactured in one piece with either the tranisition part 3 or the stem S and can then be plugged into a correspondingly designed indentation 9 tFigure 4) of the respec~ive complementary part. Preferably a snap-on connection 10 is provided which ensure~ a firm connection of the link 7 in the tran~ition part 3 and/or stem 5.
The leaf spring 6 or the link 7 are arranged and desi~ned in such a way that the brush head 1 can only be deflected in the direction indicated by an arrow in Figure 2.
15 In the case of the link not being connected in one piece - with the brush head 1 and the stem 5, it can be pu~hed onto the link 7 in the form of an annular element prior ~- to as~embly.
Otherwise, the jacket 8 can be applied as one piece around the leaf s~ring 6 or the link 7 by means of : injection moulding. In the case of the jacket 8 consii~-ting of a material which does not form a firm connection . with ~he material of the transition part 3 or of the stem 5, or is difficult to bond, a mechanical anchoring of the jacket 8 (see Fiqure 3) can al~o be provided, in which case indentations or undercuti~ 11 can be provided in the de~lecting part 4 and/or at the end of the stem 5. The ~ackati 8 ~uld then have a ~lit (not represen~ed) for push~ng it on sideways, which can be bonded; if required.
