FOLDING MONXTO TOOTH BRUSH

The present invention relates to a foldable toothbrush that fits in a small space, and which also includes other means for daily oral hygiene treatment and the possibility of using the toothbrush arm as a shaving head for a blade.

Foldable toothbrushes currently in use are large and non-cleaning (U.S. Patent Nos. 5033154, 5432971, 5442831, 5464294). Most foldable toothbrushes have a rectangular, narrow and short brush that cannot be rotated in a different position to the brush handle, making it difficult to effectively clean the tooth surfaces between the hard to reach or removed teeth. A straight brush also makes it difficult to hold the toothbrush in the correct position, which sometimes places too much pressure on the tooth surfaces or gums and gumline and damages the area, while other areas are left uncleaned due to inadequate contact and bacteria in the mouth can cause

Also, the existing toothbrush or toothbrush brush parts cannot be replaced, but the worn toothbrush must be replaced with a completely new toothbrush. In addition to current ones. other important dental hygiene tools, 4 «4 4 4 * · 'such as toothpick, curette (fine tooth scaling tool used by a dentist to remove tartar), tooth mirror, 4' · '* · gum rub, toothbrush and toothbrush ·; · *: Dental floss. Despite the lack of equipment, current foldable toothbrushes, when folded, take up a large volume, or • ·, *; ·, collect moisture, and carry them along with toothpaste and toothpicks, such as a shirt, jacket, trousers, or evening dress pocket. . In particular, many people find it difficult to maintain and find different oral hygiene tools.

The foldable toothbrush of the invention provides a significant improvement in the above drawbacks. To accomplish this: *: The foldable toothbrush of the invention and its accessories are characterized in what is stated in the characterizing part of claims 4, 4 and 3.

The bristles of the brush (5) form a plane of 4,107,369 at an angle of 3580 ° to provide the correct brushing position. In this case, the angle of the plane is 45 ° (6) and the brushes are shaped in the direction of the shaft so as to conform as much as possible to the anatomy of the teeth, with the greatest possible contact between the brush and the teeth.

Figure 3A is a top view of a toothbrush according to the invention. The curette (10) and toothpick (11) are folded around the joint (a) inside the shaft (2). In addition, the toothbrush (9) and the floss holder (l), as well as the flute groove (13), are aligned with the shaft. Figures 3B and C illustrate a front view of a toothbrush with a knob (14) and a groove (15) for attaching a toothbrush holder (1); appear. The brush (5) is rotated around the joint so that its position is no longer parallel to the shaft, but is more suitable for cleaning, for example, the spaces between the removed teeth. In the illustration, the brush at the end of the 3D toothbrush is removed and replaced with a razor shaving head (s).

In the toothbrush of Fig. 4, the operation of the brush head (4), the brush (5), the arms portions (2, 3) and the joints (a, b, c) corresponds to a toothbrush similar to Fig. 2.

For example, there are six recesses (28) below the brush (5). When turning the brush (5) «· ·« «• · the stop mechanism (27) on the arm enters into the recess (28) at the bottom of the brush • · * ... * and prevents the brush (5) from rotating. When attaching the actual brush to the brush head (5), the knobs (32) in the brush are pressed, the retaining mechanism (33) going backward and releasing the piston (30) easily into the circular cylinder (31), whereby the retaining mechanism (33) engages the piston (30). inside the narrower point (34), and prevents the brush (5) from coming off the shaft.

In Figure 5B and D, the bristles are shaped at an angle of 45 ° (6). Figure 5B shows the shape of the brush head (5) in front of the shape and Figure 5D shows the profile of the brush. During brushing, the points of the higher bristle busts (37,39) penetrate into the spaces between the teeth and the point of the low bristles (36) touches the tooth surface and the gum line. At the same time, the ends (38) of the long bristles (26) on the edge, which are slightly longer than the adjacent bristles (26b), rub the surface of the gums and clean the occlusion. Figure 5C shows the brush (5) from the rear. The bristle bouquets are shaped so that they are lower in the center of the brush than at the ends of the brush and conform to the curved surface of the tooth. Figure 5E shows. a top view of one brush head from above, and in Figure 5F, an alternative shape of the brush head (5) with a profile similar to a conventional brush at 90 °.

In Fig. 6B, the angle α of the brush lines ac and ab is 35 ° to 80 °, but the tufts at acej form an inwardly curved surface, with the tufts in the center of the tuft being lower than the tufts in the longitudinal direction. at the edge cj, and ae and cj are slightly curved according to the curved shape of the jaw. Also a-c and e-j are slightly curved due to the slightly curved shape of the crown of the teeth.

In Figure 6C and D, the design of the brush plane a-c-j-e corresponds to Figure 5B and C

presented design. The angle of the brush b-a-c a is 45 ° and there are three narrow ridges (3, 4, 5) which clean the teeth between the broom brushes. The tooth surfaces as well as the gum line are cleaned by valleys (7, 8) between the ridges (3, 4, 5), which are about 2 to 4 times wider, and are narrower (6, 9) at the edges of the brush. In the picture, the higher, round bristle bundle formations (1, 2) on the edge a-e illustrate the gums surface and clean the closures. The brush is shaped such that the bundles of the bristles are lower in the center of the brush than at the ends of the brush and mimic the curved surface of the tooth to form an elliptical paraboloid-like plane. Instead of three narrow ridges (3, 4, 5), the bristle may have more than one or more ridges, whereby the number of valleys between them, 1 to 4 times wider, and the number of bristle massaging masses between the bridges will also change. The size and shape of the brush depends on the age of the brush it is meant to be.

Figure 6E shows the literature of a conventional toothbrush::: recommended brushing technique, with no tooth surface applied o · .'j *. pressure. It is clear from the picture that if you brush your teeth without the pressure of 300-400 grams, the tooth surface and the brush. contact is very small. Figure 6F shows the contact between the brush and the tooth surface and the gums according to the invention when brushing without pressure at the recommended brushing angle of the literature. It can be seen that the contact with the tooth surface. , And between the brush and the gum line and the brush is perfect.
