Abstract

(57) [Summary] [Problem] To obtain a handle-handle toothbrush that is easy to operate and does not apply too much pressure, brushes teeth more easily than a long handle-handle toothbrush. A conventional long handle handle is formed into a short handle handle A so as not to brush the teeth with the palm of the hand.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a toothbrush in which the way of holding a toothbrush easily and naturally approaches the ideal way of holding a toothbrush. More specifically, the present invention relates to a handle of a toothbrush.

[0002]

[Prior art]

 As shown in Fig. 11, conventional toothbrushes are known to have a long handle handle with a long handle handle, or to have a hand-fitted, easy-to-hold palm. This is designed to hold the long handle handle a with the palm of the hand and apply the brush part c to the teeth to apply the pressure of the brush part c to the teeth. Also, gripping the long handle with the palm of the hand stabilizes the movement of the brush.

[0003]

[Problems to be solved by the invention]

 With regard to the pressure of the brush portion c on the teeth as described in the prior art, in the conventional method of gripping the long handle, the fulcrum of the lever principle and the index finger are attached to the little finger holding the long handle. There is an emphasis point on the brush and the thumb side, and an action point on the brush part, or a fulcrum on the forefinger and thumb, an emphasis point on the little finger side, and an action point on the brush part. For a long time, a large amount of pressure is inevitably generated. When trying to reduce the pressure, the force on the power point side must be released extremely to reduce the pressure. You can reduce your strength when you concentrate on polishing your mind, but if you use it habitually every day, it will become more powerful and put more pressure. Unnecessarily high pressure is said to be one of the causes of gum damage. The conventional toothbrush that grips the long handle handle a with the palm has a problem in that, due to the principle of leverage, a large pressure is necessarily applied to the brush part c.

[0004] In addition, although the latter stabilizes the movement of the brush part C, the brush part C, which is an ideal way of brushing teeth, is moved in small increments, vibrated small, and finely. In terms of movement, gripping the long handle a loses the freedom of the wrist and makes the wrist and arm muscles move harder, making it difficult to move finely. doing.

[0005] In addition, when the above two problems are synergistically attempted to move the brush part finely, a force is applied to the wrist, the arm or the finger, and a large pressure is applied to the brush part. . If you try to reduce the pressure, hand movements tend to be large. As described above, the method of gripping a long handle has the problem that it is difficult to brush long and stable teeth while reducing pressure.

[0006] A long handle has a long appearance, so it is customary to grip the long handle. It is habitually difficult for doctors to hold the pencils and penmanship brushstrokes shown in Fig. 13, which are recommended by the doctor. Of course, even in the case of a long handle handle, you can hold a pencil or a brush for penmanship, but as shown in Figure 13, pass through the ring made by the thumb and forefinger, and on the back of the hand, the long handle handle When the rear part of the handle comes out, and when the rear part of the long handle comes out on the little finger side of the palm as shown in FIG. 12, and depending on where you brush your teeth, it is inevitable to switch the long handle. Occurs. At the time of this change, I try to hold a long handle habitually. Depending on the location of the tooth to be brushed, there is a problem that the long handle can hinder the habit of holding a pencil or penmanship.

[0007] The present invention has been made in view of the above-mentioned problems of the conventional invention, and has as its object the purpose of applying a toothbrush without excessive pressure, providing a finer, longer and more stable state. Provide a short-toothed toothbrush that is designed to be easy to operate, and that makes it easier to hold a toothbrush and how to hold a pencil or calligraphy brush naturally. It is assumed that.

[0008]

[Means for solving the problem]

 In order to solve the above-mentioned problem, the short handle toothbrush in the present invention has a short handle handle so that a long handle handle can be brushed with fingers while holding the handle handle with fingers.

[0009] The handle is shortened, or the handle is shortened from the shortened handle to the neck. You can also make it easier to polish.

[0010]

[Embodiment of the invention]

 An embodiment of the invention will be described with reference to the drawings. 1, 2, 4, 6, 8, and 9, the handle handle (A), which is a part of the toothbrush, is formed by using a synthetic resin material, for example, and shortening it by molding. Has been established. The shortened handle is formed integrally with the neck (B).

The cross section of the handle (A) is formed in a circle (FIGS. 3 and 5), an ellipse, or a polygon (FIG. 7).

In FIG. 2, for example, hemispherical projections (G) are arranged on the surface of the handle handle (A) so as to be more slippery and to be held. The whole handle or the protrusions (A) can be formed of a soft synthetic resin.

In FIG. 4, for example, a projection (G) having a semicircular cross-section is formed on the surface of the handle handle (A) in a strip-like shape at a predetermined interval so as to be held more slippery. ing. Also in this case, the handle handle (A) as a whole or the projection can be formed of a soft synthetic resin.

In FIG. 6, a handle is provided on the surface of the handle (A) in the longitudinal direction of the handle (A) so that the handle can be held more slippery. By using a soft synthetic resin as the material, it becomes more slippery and can be held.

8 and 9, the handle (A) is formed with an uneven portion (H) from the handle (A) to the neck (B) so that the handle can be held more slippery.

[0016]

[Effect of the invention]

 Since the present invention is configured as described above, the following effects can be obtained.

Since the handle of the short-handled toothbrush of claim 1 is short, the fulcrum and the point of force are concentrated at the finger having the handle, so that the brush is polished with less pressure than when a long handle is held. You can do it.

[0018] Since the handle of the short handle toothbrush of claim 1 is short, the handle has a handle only at the fingertip, and a large force is not required for the wrist and the arm, and the muscle of the wrist and the arm can be hardened. Soon, operability is much easier and finer movement is easier than holding and polishing a long handle without hardening the wrist.

Since the handle of the short handle toothbrush of claim 1 is short, the movement of the rear portion of the handle moves within the palm without being disturbed by the back of the hand, and the brush moves without any special holding. As a result, the teeth can be freely and continuously brushed stably.

Since the handle of the short-stalk toothbrush of claim 1 is short, it cannot be physically gripped, and it is inevitable and naturally the ideal way to hold a pencil or the brush for penmanship. The way of holding can be made into a habit.

[0021] Costs can be reduced by the shortened handle.

As the handle is shortened, resources can be saved.

Since the handle is shortened, garbage is reduced and the environment is friendly.

[0024] Because it can be shorter than the conventional long-handled toothbrush as a whole, it does not take up much space, and it is easy to carry in women's bags, pockets, travel bags, and the like.
