DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be specifically described below based on an embodiment shown in the accompanying drawings.

FIGS. 1 to 5 show a first embodiment of a toothbrush device having a substantially concave cross section according to the present invention. The basic structure of this embodiment will be described with reference to FIG.

There is a conversion means (20) for converting the occlusal movement of the upper teeth (1) and the lower teeth (3) into the movement of the pad means (10), and the conversion means (20) has the conversion means (20). The pad means (1) for pressing and cleaning the gums and teeth activated by
0) and upper teeth (1) An example of loosely fitting the shape portion will be described.

The mounting means (40) comprises an occlusal surface (4), an outer surface (5) and an inner surface (6) of the upper tooth (1).

[0010] It is provided so as to fit the gums (2) in a state where a soft elastic body (21) is covered with a reinforcing material (27) having high rigidity, and linear projections (11) are provided on the surface of the pad means (10). ) Is molded.

The mechanism for starting the pad means by the converting means (20) will be described with reference to FIG.

The movement of the upper teeth (1) and the lower teeth (3), that is, the occlusal force is the force F (32) from the upper teeth (1), which is the inner wall A (26).
Component force f (33) on the inner wall (30) and component force g (34) on the inner wall (30)
In addition, the force F (28) from the lower tooth (3) is applied to the outer wall A (29).
Component force h (35) on the outer wall (31) and component force j (36) on the outer wall (31)
Can be divided into

For ease of understanding, it is limited to the gum (2),
The state in which the pad means (10) is activated will be described.

A tensile force acts on the inner wall A (26) by a component force f (33), and a compressive force acts on the outer wall (29) by a component force h (35), but the outer wall (29) is reinforced. Material (2
5), the deformation is prevented even if a compressive force acts on the outer wall (29), and the shoulder portion (9) at the base of the pad means (10).
Stiffeners (25) and (27) are broken, the shoulder (9) is thin and easy to bend, and the center line (37) and component force f (33) are
Since the angle α (38) formed by the component force h (35) is an acute angle, the compressive force acts by the component force h (35) when the movement is further increased, whereby the direction of the center line (37) of the shoulder portion (9). A force acts clockwise (not shown) in the vicinity of the shoulder portion (9), and as a result, the pad means (10) presses the gum (2).

A bending moment acts on the outer wall (29) as a reaction force in the direction opposite to the gum direction.
5) causes the balance deformation within the elastic range and prevents the retrograde deformation.

At the same time as the pressing of the gums, the tooth surface is cleaned,
This state will be described with reference to FIG.

When the positions of the upper teeth (1) and the lower teeth (3) are advanced from the state shown in FIG. 2, the inner wall A (26) becomes thinner. Therefore, the gum (2) and the tooth (1) have linear protrusions (1
When 1) is pressed, it slides to scrape off the food waste on the tooth surface and allow cleaning.

The above is the description when the occlusal force acts on the upper teeth (1) and the lower teeth (3).

When the occlusal force is reduced, the material of the converting means (20) is the soft elastic body (21), so that the original shape is restored.

Therefore, the force acting on the upper tooth (1) (3
2) is also reduced, and the inner wall A (26) shrinks and the gum (2) and upper teeth (1) return with the linear projections (11) being pressed, and the food waste on the tooth surface is scraped off and cleaned. Will be possible.

In the description of the converting means (20), the upper teeth (1) and the lower teeth (3) have been occlusal in the vertical direction, but the pad means (10) is likewise in the case of forward and backward and lateral rotation. An example in which the gum (2) is pressed will be described with reference to FIG.

By rotating the teeth laterally in the direction of the arrow (39), the space (41) contracts and a compressive force acts in the vicinity of the shoulder (9), so that this force causes the pad means (10).
Will press the gums (2) and upper teeth (1).

On the contrary, the inner space (42) is expanded, and the inner gum (63) is released from the pressing of the pad means A (12).

It can be easily understood that the same effect can be obtained when the jaw is moved in the front-back direction.

At the same time, the gums (2) and the upper teeth (1) are slid together with the linear protrusions (11) pressed, and the meal residue on the tooth surface can be scraped off for cleaning.

The above description is for the case where the toothbrush device is mounted on the upper teeth (1), but it is also clear that the same effect can be obtained by mounting it on the lower teeth (3).

It is also clear that the same effect can be obtained even if the toothbrush means is attached to a part or all of the teeth.
Shows an example of a state in which it is attached to a part of the back teeth.

FIG. 6 shows the second embodiment, which is an example in which the pad means is activated by utilizing the pressure transmissibility of a fluid such as liquid or gas.

The cross-sectional shape is substantially concave, and the front and rear (not shown) of the space (41) are closed to seal a fluid body (45) of liquid or gas therein.

[0030]

In the above state, the force of the jaw, that is, the occlusal movement between the upper teeth (1) and the lower teeth (3), causes the pressure to act on the fluid (45), which is the same on the entire concave inner wall due to the so-called Pascal principle. The strength of pressure is transmitted.

Pad means B (46) for hitting the gums (2)
By making the wall thickness (47) of each of them smaller than the other wall thicknesses (55), bulging deformation occurs due to pressure, and the gum (2) can be effectively pressed.

The thickness (4 mm) near the gum (2) and the tooth (1)
By thinning 8) and raising the linear protrusions (11), the boundary between the upper teeth (1) and the lower teeth (3) is repeatedly pressed, and especially plaque and tartar are removed.

FIG. 7 shows a third embodiment, in which a substantially H-shape is formed, and both ends of the sliding plate (51) are connected to the inner side wall (52) and the outer side wall (53) and the upper teeth (1). Lower teeth (3) are omitted

The thickness of both ends of the sliding plate (51) at the connecting portion is thin, and the narrowed portion A (54) and the narrowed portion B are formed.
By forming (55) and using a flexible material as the material, the hinges (56) can be easily bent at the constricted portions by swinging the inner wall (52) and the outer wall (53). Will have the same function as.

Pad means C (57) and pad means D (58), which are respectively formed of removable soft materials, are attached to the extended portions of the inner wall (52) and the outer wall (53).

In the third embodiment, the conversion means for moving the jaw laterally and pressing the pad means C (57) against the gum (2) and the tooth (1) by the movement will be described.

The lower tooth (3) slides in the direction of the arrow (59) to come into contact with the outer wall (53) at the contact point (60),
The upper teeth (1) are in contact with each other at a contact point (61) on the inner wall (52).

When the lower tooth (3) is further slid in the direction of the arrow (59), the lower tooth (3) comes into contact at the contact point B (67), and the hinge (56) is used as a base point for the lever. In principle, the pad means C (57) moves toward the arrow (62) and presses the gum (2).

The pad means C (57) and the pad means D
In (58), the protrusion A (64) and the protrusion B (6
Since 5) is provided, it is possible to scrape off the meal residue on the tooth surface and press the boundary between the gum and the tooth.

It can be easily understood that the pad means (58) presses the internal gums (63) by sliding the lower teeth (3) in the opposite direction of the arrow (59).

[0042]

As described above, a simple toothbrush device is attached to a tooth, and by moving the tooth, the pad means presses and cleans the gum / teeth to improve the blood circulation of the gum and to adhere to the tooth surface. It is possible to clean the eaten meal and prevent alveolar pyorrhea.

Further, by making the pad removable, the shape of the pad surface can be freely selected, so that the health management of the gums and teeth can be made more detailed and the range of applications can be expanded.

Further, since the pad means can be put in the mouth and used, it is possible to use it easily without being limited by time and place.
