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 reached. 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 plasticized PVC.
Description
- 1 - 75897 Toothbrush with a deflecting part having a deflection profile The invention relates to a toothbrush with a deflecting part which has a deflection profile and is positioned I 5 between brush head and stem, serving to deflect the brush head when a certain contact pressure is reached. * ;German Offenlegungsschrift 3706 f 345 discloses a similar toothbrush for manual or mechanical operation. With this toothbrush the brush head can be deflected on the brush 10 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 15 high a contact pressure is exceeded, the brush head can move from its previously extended position into a deflected position with, respect, to the longitudinal axis of the stem. This gives a signal to the user; further brushing of the teeth would also at least be made snore difficult, 20 if not impossible. She deflection can occur more or less progressively 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 exposed there is a risk of 25 injuries to the mouth because of the edges,, and of pinching if a longitudinal slit is presentt when the toothbrush is used. ;The object of the invention is to specify a toothbrush with a deflecting part hairing a deflection profile, which 30 toothbrush has an attractively shaped appearance without the deflecting being obstructed., and is free from edges presenting a risk of injuries and free from slits. ;This object is achieved by a toothbrush having the features of Claim 1 or Claim 2. ;- 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 embodiments with reference to drawings, 5 in which: ;Figure 1 shows a plan view of a toothbrush£, ;Figure 2 shows a side view of the toothbrush, ;Figure 3 shows a deflecting part on an enlarged scale,, Figure 4 shows a design variant of a deflecting part on 10 an enlarged scale. ;A toothbrush consists of a brush head 1 with the bristles 2 and a transition part 3, a deflecting part 4 and a stem 5. The deflecting part 4 connects the transition part 3 to the stem 5v serving as handle. .The deflecting part 4 can have a metallic 15 leaf spring 6 or a link 7 of plastics material. The metallic leaf spring or plastics link is covered at least on the front and back thereof by an elastoirer. Preferably f the link 7 and the leaf spring 6 are entirely enclosed by a jacket 8 soade of an elastomer, covering all sharp edges of the leaf spring 6 or of the link 7. The jacket 8 made of 20 elastomer is designed so that it forms a positive connection of the free end of the transition part 3 of the brush head 1 with the connecting end of the stem 5 and nevertheless enable® the leaf spring 6 or the link 7 to be deflected. The jacket 8 can also serve the optical 25 design of the toothbrush 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 stem 30 5,, for example by means of the injection moulding procedure . In this cese, the jacket 8 can either have been applied previously or it can be applied subsequently^ when the transition part has already been firmly connected by means of the leaf spring 6 to the stem 5. ;- 3 - ;In the case of the deflecting part 4 having a link 7, the brush head 1 can be made without bristles 2e the transition part 3, the deflecting part 4 and the stem 5 can be manufactured of one material in one manufacturing step, 5 for example by injection moulding. The link 7 can also f be manufactured in one piece with either the transition part 3 or the stem 5 and can then be plugged into a * correspondingly designed indentation 9 (Figure 4) of the respective complementary part. Preferably a snap-on 10 connection 10 is provided which ensures a firm connection of the link 7 in the transition part 3 and/or stem 5.
The leaf spring 6 or the link 7 are arranged and designed 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 pushed onto the link 7 in the form of an annular element prior to assembly.
Otherwise, the jacket 8 can be applied as on® piece 20 around the leaf spring S or the link 7 by aae&ns of injection moulding. In the case of the jacket 8 consisting of a material which does not form a firm connection with the material of the transition part 3 or of the stem 5, or is difficult to bond, a Mechanical anchoring of the 25 jacket 8 (see Figure 3) can also be provided, in which case indentations or undercuts 11 can be provided in the deflecting part 4 and/or at the end. of the stem 5. The jacket 8 would then have a slit (not represented) for pushing it on sideways, which can be bonded# if required. 30 The metallic leaf spring 6 consists of electro- •». galvanised or chromium-plated steel, or of a rust-proof metal or metal alloy, preferably a copper beryllium alloy.
The elastomer of the jacket 8 preferably consists of 35 natural or synthetic rubber, such as styrene-butadiene - 4 - rubber, butyl rubbert, ethylene rubber, propylene rubber, silicone rubber or an ethylene vinyl acetate copolymer or plasticised PVC, in which case a Shore hardness of A 40 to 80 is preferably to be provided.
