Description

Toothbrush whose curved bristle carrier is rotatably attached to the front handle.

'The invention relates to a toothbrush whose curved bristle carrier rotatably mounted on the front handle part and is adjustable in a longitudinal position and a transverse position relative to the handle.

A toothbrush has been proposed, the bristle carrier of which is designed as an independent curved part and is rotatably attached to the handle, so that it rectified as needed can be adjusted with the handle or across the handle. It is desirable that the curved bristle carrier in the longitudinal position continuously merges into the handle and in the transverse position with its surface is essentially parallel is aligned to the longitudinal axis of the handle »

To do this in a simple and cheap way, see the invention proposes that the handle part is made thinner than the rest of the handle and this with one to the front handle part protruding nose is provided, under which one end of the bristle carrier is pushed and so the handle part according to the Curvature of the 'bristle carrier can be kept bent. Here is preferably the bristle carrier or the front one Handle part provided with a pin which engages in a recess in the front handle part or the bristle carrier and is held in this by a bead.

Another feature of the invention "is that the Pin and the recess identify resilient radial projections and detents, which in the longitudinal position and the transverse position of the bristle holder into place.

In the following, an embodiment of the toothbrush according to the invention E _r to the drawings will be explained. The drawing shows:

Fig. 1 shows a toothbrush from the side with in the same direction like the handle of the bristle carrier,

2 the brush with the bristle carrier placed perpendicular to the handle, also from the side, partly in section, and

Pig * 3 a section along the line III-III in Pig. 2 «

The illustrated ¹ toothbrush has an elastic handle 1, in particular made of plastic, the front part 2 of which is intended to hold the curved bristle carrier 4 is made significantly thinner than the rest of the handle 4e.il. Diesel front handle part 2 is perforated so that it has a recess 8 which is provided with a radial stop surface 10 which forms a detent. The front handle part 2 also has a slot 11 extending from the recess 8.

The peg 7 of the brush holder 4 is seated in the recess 8 axially immovable, but rotatable. The pin 7 is in the cross cut with four gates evenly distributed around the circumference 9 and has a radially projecting bead 12 at its end.

The slot 11 gives the R ^ ndteile of the recess 8 the Ability to resiliently yield to the 7 in Hold tight the working positions of the bristle holder. If the bristle carrier 4 compared to the handle of a Turned to the other position, the projections 9 effect an increasing widening of the recess until the next projection engages behind the surface 10. The resilient Naehgie "*

O «*

Bigkeit of the edge parts of the recess 8 also enables that Passing the bead 12 of the pin 7 through the " acceptance "when inserting or changing the bristle ice = - les. The? / Ulst, which is used to hold between the bristle part and the handle, is also inserted into the free end of the pin protruding rivets made of plastic can be achieved.

Due to its small thickness, the front part 2 of the Also bend the handle, as 3? Ig · 1 shows. A protruding rabbit 3 is formed at the transition from the thick to the thin handle part. One end 6 of the bristle carrier is pushed under this rabbit in its position in the same direction as the handle, whereby the part 2 of the handle of the curvature of the bristle carrier 4 is kept bent accordingly and jamming of soft tissue between the handle and the bristle part ata ^ e closed will. ".

In the position of the bristle holder with respect to the handle shown in Fig. 1, the brush is suitable for cleaning the Molars, canines and incisors from the inside. It is moved back and forth across the row of teeth in a horizontal position. During this movement, the bursts 5 penetrate into the basin between the teeth and brush them completely from the beginning at the neck of the tooth along the entire tooth, including of the crowns. at the molars. This cleaning must of course from one tooth to the other on both sides of the dentition, up and down, progress.

Are the upper and lower parts of the bit all around from the inside cleaned, the bristle part is overcome by overcoming the plague-holding force opposite the handle by 90 ° into the one in Pig. 2 shown Position rotated.

To clean all teeth from the outside, the brush is now from section to section, always several teeth above and below or, if desired, only capturing above or below,

placed on the teeth with the handle pointing straight down. The curvature of the bristle carrier is chosen so that See that the bristles are in good contact with the curve of the dentition. By moving up and down the. Brush can be a very Thorough and yet gentle cleaning of the front parts of all teeth "right down to the usual brushes is difficult achieve accessible corners.

Not only is the "described brush ideal for perfect tooth cleaning | it also protects the enamel, and it is also very convenient to use. Both the horizontal back and forth movements and the vertical up and down movements are very simple Movements that can be easily performed with the hand.

Of course, numerous deviations from the training shown are possible within the scope of the invention. So can E.g. the projections 9 of the pin 7 tua-d the catch 10 of the Recess.8 can also be designed differently than shown here.
