JP3222926U - Toothbrush that can change neck angle in handle of toothbrush - Google Patents

Abstract

A toothbrush having a variable neck angle is provided. An angle variable portion provided with an angle variable portion capable of changing a neck angle includes an angle change dial, a worm, and a worm wheel, and meshes the worm, worm wheel, and both gears. Equipped with an angle change dial coaxially with the worm. By turning the angle change dial, the rotation of the worm is transmitted to the worm wheel. Retained. You can brush your teeth in that state, and when you brush your teeth, a reaction force is applied from the teeth to the brush, and the neck of the same body tries to warp, and a force is applied from the worm wheel to the worm. The brush remains stationary without rotating, and the position of the brush remains unchanged. The position of the brush changes only when the angle change dial is turned. [Selection] Figure 1

Description

The present invention relates to a toothbrush handle in which the neck angle can be easily changed before using the toothbrush.

  Usually, a toothbrush is composed of a rod-shaped handle and a brush of a head, and is integrated and put into practical use.

However, with a rod-shaped handle, even if the position and angle of the hand are changed according to the arrangement and orientation of the teeth in the mouth, the brush does not reach the target tooth, the angle is different, and it is not enough to be polished, There was a problem that unpolished material was generated.

  Toothbrushing is essential every day, and there was a concern that there might be problems in the future if left unpolished.

  As an improvement measure, there is a slightly curved shape which is devised so that the shape of the toothbrush handle is easy to hold.

  However, even with this method, in order to ensure that there are no unpolished teeth according to the arrangement and orientation of the teeth in the mouth, a good tooth brushing technique is required, and guidance and training by specialists are being conducted.

Utility model S61143342

  The problem to be solved is tooth brushing, even with a rod-shaped handle, even if the angle and position of the hand is changed according to the tooth arrangement and orientation in the mouth, the brush does not reach or the angle is different, even if you intend to polish Polishing is not enough and there is a possibility that unpolished material may occur.

  The present invention is characterized in that the brush touches any tooth in order to change the neck angle of the toothbrush handle.

  In the toothbrush handle of the present invention, by turning the equipped angle changing dial to the right or left, the worm wheel is rotated through the worm, and the brush angle of the neck tip that is the same body as the worm wheel is changed to brush the teeth. There is an advantage of improving the brushing effect by contacting any tooth.

In addition, compared to a rod-shaped handle, the position of the hand holding the toothbrush changes, the polished state is easy to see, and it is easy to visualize in a mirror or the like.

FIG. 1 is an overall explanatory view in which an angle variable portion is provided on the toothbrush handle, and an angle variable portion cross-sectional explanatory view.

  The purpose of changing the brush angle at the neck tip was achieved with the minimum number of parts by turning the angle change dial while holding the handle.

In addition, the reaction force of the brush when brushing teeth causes the neck to warp and the worm wheel, which is the same body as the neck, tries to rotate, but the worm does not rotate, the catch and the worm wheel are stopped. First, we realized that brushing can be performed in a stable state with the brush angle changed.

  FIG. 1 is an overall explanatory view of an embodiment of the present invention and an explanatory cross section of an angle variable portion.

  1 is a handle, 2 is a neck, 3 is a brush, 4 is an angle changing dial, 5 is a worm, 6 is a worm wheel, and 7 is a shaft.

  In the overall explanatory view of the embodiment of the present invention shown in FIG. 1, by holding a handle and turning a four-angle changing dial, the two-neck angle can be changed and the three brushes at the tip of the two-neck can be positioned.

  In the cross-sectional explanatory view of the angle variable portion in FIG. 1, 4 is an angle changing dial, 5 is a worm, 6 is a worm wheel, and 7 is a shaft.

  In the cross-sectional explanatory view of the angle variable part in FIG. 1, 5 worms are provided coaxially with the 4 angle change dial, and by turning the 4 angle change dial, 5 worms rotate, and 5 worms rotate, The rotation is transmitted to the 6 worm wheel, and the brush mounted on the other end of the neck, which is the same body as the 6 worm wheel, moves and the brush can be positioned.

  The arrangement of teeth in the mouth is a semi-circular arrangement that spreads out in the back, and it is difficult to brush by brushing the teeth together in the upper and lower sides and inside and outside, making them lightly contact at an angle of about 45 degrees.

The toothbrushing situation may end with the brushing being judged well because of the habit and familiarity of the brushing person.

By changing the neck angle of the toothbrush, the operability of the brushing operation is improved, and the brush can be applied to any tooth.

When brushing teeth, a reaction force is applied from the teeth to the brush, and the same neck tries to warp, and a force is applied from the worm wheel to the worm, but the worm does not rotate due to the difference in gear ratio and gear angle, so the position of the brush Is held stationary.

The brush angle is changed only when the force is transmitted from the worm to the worm wheel by turning the angle change dial.
