JPH07111915A - Tooth brush bent into v-shaped form in stem - Google Patents

Abstract

PURPOSE:To enable teeth to be vertically brushed in a natural brushing way with a brush placed parallel to the row of teeth by bending the stem in a V-shaped form while enabling the tip of brush part to be reversibly rotated relative to the stem. CONSTITUTION:Since a tooth brush is bent in a V-shaped form in the stem 2, the brush 1 is moved parallel to the row of teeth only by moving up and down (vertically) the hand gripping the stem 2, and it enters gaps between teeth to sweep away cleanly leftover dregs or the like. Then, when the bent shape of the stem 2 and brush part 1 is fixed to either direction, two tooth brushes bent to opposite directions are needed. However, teeth in either of left or right sides can be brushed with one tooth brush bent in either directions when only the brush part 1 is adapted to be reversibly rotated relative to the stem by the use of a pin 3.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a toothbrush used for brushing teeth.

[0002]

2. Description of the Related Art A conventional toothbrush has a bar-shaped, almost straight, integral type, but there is also a toothbrush that is bent several degrees in the implantation direction. The implantation direction means the A direction shown in FIG. Recently, there are electric toothbrushes, but the shape and movement are the same.

[0003]

When brushing with a conventional toothbrush, the handle of the brush has a shape protruding to the front of the mouth or to the side. Therefore, even if there is a slight difference in the way of gripping, a difficult exercise using the wrist must be performed in order to perform the correct vertical polishing along the teeth and the teeth with the thumb on the face side.

[0004] Further, even adults have difficulty in vertical movement along the teeth and teeth, and therefore, there are many people who do horizontal polishing in the shape of teeth and intersect with each other, causing damage to the teeth and gums, and it is difficult to remove food residue. .

[0005]

In order to achieve the above object, the present invention bends a part of the handle in a dogleg shape so that the toothbrush is parallel to the teeth, but the handle can be naturally held vertically. I chose
Therefore, the movement of the hand is vertical (longitudinal) movement.

[0006]

[Function] Since the handle of the above toothbrush is bent into a dogleg shape, the brush moves in parallel with the arrangement of the teeth and enters the gap between the teeth only by moving the hand holding the handle up and down (vertically). It cleans up the food left over.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the drawings, an embodiment will be described with reference to FIG.
"A", "c", and "e" are brushing with a toothbrush that is bent in a V shape on the right side. b, d, and f indicate how to brush with a toothbrush which is bent in an inverted shape on the left side.

As mentioned above, if the handle and the brush are fixed in one of the bent shapes, the other shape and the opposite shape are required. Therefore, if only the brush part is made anti-rotatable as shown in Fig. 2, it is possible to polish with one of which is bent in either direction.

[0009]

[Effects of the Invention] Vertical polishing can be performed by aligning the tooth arrangement and the toothbrush in a parallel manner with a natural polishing method.
