Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a toothbrush that is easy to use and can freely bend the angle of the handle of the toothbrush according to the toothbrushing posture.

[0002]

[Prior art]

 This conventional toothbrush generally has a rod-shaped body with a straight handle, and there is also a handle in which part of the handle or the brush portion is bent to polish a place that is difficult to polish with a rod-shaped toothbrush.

[0003]

[Problems to be solved by the device]

 By the way, the shape of the oral cavity, the alignment of teeth, and the shape of teeth are different for each person.

Therefore, in the commercially available products such as the above-mentioned conventional techniques, since the handle is a rod-shaped body, the angle of the brush portion cannot be freely changed, and there is no one that can adapt to these conditions. Therefore, there is a problem in that teeth are hard to brush.

That is, when brushing teeth originally, it is preferable to apply the brush portion to the tooth at a right angle, but if the handle is a rod-shaped body, it is difficult to apply the brush portion to the tooth at a right angle, or Brushing the front and back surfaces, or the left and right teeth requires the operation of the brush part facing up and down, and the operation of switching between the right and left hands. .

Further, conventionally, there is a problem that toothbrushing is troublesome because it is necessary to use another toothbrush for a portion that is difficult to brush with a toothbrush or a special brush between teeth.

Therefore, the present invention has been devised in view of the above-mentioned problems of the prior art. It is possible to freely brush the teeth according to the shape of the oral cavity, the alignment of teeth, the shape of the teeth, the position of the teeth, etc. The purpose is to provide a bendable toothbrush.

[0008]

[Means for Solving the Problems]

 In order to achieve the above object, in the toothbrush of the present invention, a bendable core member is arranged at the center in the axial direction, and a core metal is coupled to both upper and lower surfaces of the core member or one of the surfaces, and A handle with a core member and a cored bar covered with a covering member that can be easily bent in a certain direction with appropriate hand force and that can retain its shape after bending, and a brush on the tip of the handle. The brush parts that have been planted are joined by a predetermined joining means.

Then, preferably, the core member is made of lead, and the core metal is made of a thin metal plate.

[0010]

[Action]

 It is difficult to polish by changing the direction and angle of the brush part by flexibly bending the handle according to the shape of the oral cavity, the alignment of teeth, the shape of the teeth, and the posture of brushing the teeth with moderate force of the hand. brush teeth.

[0011]

【Example】

 An embodiment will be described with reference to FIGS. 1 to 11. At a center of the toothbrush handle 1 in the axial direction, as shown in FIGS. Auxiliary member 12, which is a core metal capable of being held in a fixed shape after bending, is connected to both upper and lower surfaces of the core member 11 or one of the surfaces.

The core member 11 is made of lead, aluminum, or other bendable material equivalent to this, and the auxiliary member 12 is made of a thin metal plate or the like, and its thickness and bending strength are appropriate. The strength is set so that it can be bent freely with the force of human hands and that it does not easily bend during brushing work after bending.

The length, thickness, width, weight and bending strength of the handle 1 are selected according to the characteristics of the body of the user F.

Further, the surface of the core member 11 to which the auxiliary member 12 is coupled is covered with a covering member 13 made of, for example, a soft synthetic resin so that the color can be freely selected.

A brush portion 2 in which a brush 3 is planted is joined to a tip portion of the handle 1 by a predetermined joining means.

The connecting means for connecting the brush portion 2 and the handle 1 is integrally provided with a connecting portion 4 having an insertion hole 41 at the base end of the brush portion 2 as shown in FIGS. The tip portion of the handle 1 is fitted into the insertion hole 41 and coupled.

Further, as shown in FIG. 4 showing the second embodiment of the connecting means, a pair of projections 14 project in a fork shape in the axial direction of the tip of the handle 1, and the connecting portion 4 at the base end of the brush portion 2 is provided. A hole 41 into which the protrusion 14 can be fitted is provided in the axial direction of the brush portion 2.

Further, as shown in FIG. 5 showing the third embodiment of the coupling means, an insertion hole 15 is provided in the distal end central axis direction of the handle 1, and the coupling portion 4 can be fitted into the insertion hole 15. The shaft 43 is integrally provided.

Further, as shown in FIG. 6 showing a fourth embodiment of the coupling means, a screw hole 16 is formed by cutting a screw 16a in the central axis direction of the tip portion of the handle 1, and the coupling portion 4 on the brush portion 2 side is provided. A screw rod 44 formed by cutting a screw 44 a that can be screwed into the screw hole 16 is integrally provided in the axial direction of the brush portion 2.

The size, weight and the like of the brush portion 2 are arbitrarily selected in consideration of the intended use and convenience of use.

The handle 1 is bent and used as shown in FIGS.

The bending direction can be changed depending on whether the front surface of the tooth is brushed, the back surface of the tooth is brushed, or the upper and lower teeth are brushed, and the brush is applied at right angles to the tooth to be brushed. In order to change each time.

Further, as shown in FIG. 7, the handle 1 and the brush portion 2 may be formed by the same member as the handle 1, and the brush 3 may be planted in the brush portion 2. In this case, not only the handle 1 but also the brush portion 2 can be freely bent into a desired shape with an appropriate hand force.

[0024]

[Effect of device]

 Since the present invention is configured as described above, it has the following effects.

(1) Since the handle can be easily bent in a predetermined direction with an appropriate hand force, the user can handle the desired tooth brushing posture, oral cavity shape, tooth alignment state, tooth shape, tooth position, etc. You can brush the tooth easily by bending the handle at any angle and brushing the brush at right angles to the tooth.

Therefore, the handle can be bent at a predetermined angle with one toothbrush, and various toothbrushing postures can be accommodated.

(2) Further, since the handle can be easily bent in a predetermined direction with an appropriate hand force, it is possible to easily adjust the angle of the handle and finely adjust it even during the tooth brushing work. You can brush your teeth according to the shape and alignment of teeth.

(3) Since the handle can be bent with an appropriate force of the hand, even when brushing the teeth of a person who cannot brush his / her teeth, such as an infant or a sick person, not the user himself, the brusher can easily brush the teeth. The angle of the handle can be adjusted and polished.
