Technical Field
[0001] The present invention relates to a quad-directional angle adjustment apparatus and a quad-directional angle adjustment brush using same. In general, brushes, especially toothbrushes are straight-type those which may not adjust their angles. However, a variety of toothbrushes which may adjust their angles are recently developed so as to help users to brush their teeth more conveniently and to every corner of the mouth.
Background Art
[0002] Conventional, angle-adjustable toothbrushes are provided in a variety of methods, however toothbrushes which may adjust angles to every direction are complicated to be assembled, thereby causing a problem which reduces productivity. Accordingly, the angles are made to adjustable in limited directions such as left, right, forward, and backward, and thus, the toothbrushes become less complicated to be assembled. However, this is insufficient to help users to conveniently brush their teeth.

Technical Problem
[0003] The task of the present invention is applied to solve the above-mentioned defects of the angle-adjustable toothbrushes and is to provide a quad-directional angle adjustment apparatus and a quad-directional angle adjustment brush using same which may be easily assembled and adjust angles in four directions, that is, left, right, forward, and backward, thereby improving productivity and providing users with convenience in brushing their teeth.
Technical Solution
[0004] For solving the above task, a quad-directional angle adjustment apparatus and a quad-directional angle adjustment brush using same according to the present invention comprises a toothbrush head unit having a C-shaped connection portion, which includes an assembly opening, in one side of the head unit and a toothbrush handle unit having a C-shaped connection portion, which includes an assembly opening, in one side of the handle unit, characterized in that the C-shaped connection portions provided in one side of the toothbrush head unit and the toothbrush handle unit have a convex connecting portion on an inner surface and a concave connecting portion on an outer surface.
Advantageous Effects
[0005] A quad-directional angle adjustment apparatus and a quad-directional angle adjustment brush using same according to the present invention, especially a toothbrush achieves the effect of helping users to brush their teeth more conveniently and to every corner of the mouth in comparison with conventional, straight-type toothbrushes. In addition, it can be effectively achieved that the toothbrush according to the present invention may reduce cost of production because being simply assembled, and thus, an angle-adjustable toothbrush with the purchasing power may be provided at reasonable prices, in comparison with conventional, angle-adjustable toothbrushes. Furthermore, when a quad-directional angle adjustment structure of the present invention is applied to an interdental brush, users may conveniently use the interdental brush so as to remove interdental food debris much conveniently through a variety of angle adjustments.

Best Mode
[0008] Hereinafter, a representative product among quad-directional angle adjustment apparatus and quad-directional angle adjustment brushes, that is, a toothbrush is described in detail.
[0009] As a structure for solving the above-mentioned task, a quad-directional angle adjustment toothbrush according to the present invention comprises a toothbrush head unit 100 having a C-shaped connection portion 110, which includes an assembly opening 120, in one side of the head unit and a toothbrush handle unit 200 having a C-shaped connection portion 210, which includes an assembly opening 220, in one side of the handle unit, characterized in that the C-shaped connection portions 110 and 210 provided in one side of the toothbrush head unit 100 and the toothbrush handle unit 200 have a convex connecting portion 130 and 230 on an inner surface and a concave connecting portion 140 and 240 on an outer surface.
[0010] Hereinafter, the quad-directional angle adjustment toothbrush with such a configuration is described in detail with reference to the accompanying drawings.
FIG. 1 illustrates a toothbrush head unit which has a C-shaped connection portion in one side according to the present invention in a perspective view.
FIG. 2 illustrates a toothbrush handle unit which has a C-shaped connection portion in one side according to the present invention in a perspective view.
FIG. 3 illustrates an assembled state of a toothbrush head unit and a toothbrush handle unit according to the present invention in a perspective view.
FIG. 4 illustrates a toothbrush which is angled forward according to the present invention in a perspective view.
FIG. 5 illustrates a toothbrush which is angled backward according to the present invention in a perspective view.
FIG. 6 illustrates a toothbrush which is angled to the left according to the present invention in a perspective view.
FIG. 7 illustrates a toothbrush which is angled to the right according to the present invention in a perspective view.
[0011] As shown in FIGS. 1 and 2, the toothbrush head unit 100 and the toothbrush handle unit 200 according to the present invention respectively have the C-shaped connection portions 110 and 210 in one side. The assembly openings 120 and 220 are respectively formed on the C-shaped connection portions 110 and 210, and thus, workability is good when the toothbrush according to the present invention is produced, because the toothbrush is easily assembled, and the assembly openings 120 and 220 are spread so that the angle is easily adjusted, when users desire to adjust the angle of the toothbrush.
[0012] In addition, the convex connecting portions 130 and 230 and the concave connecting portions 140 and 240 which enable the toothbrush to be angled forward and backward as well as to the left and right in a stepwise manner are disposed on the C-shaped connection portion 110 provided in one side of the toothbrush head unit 100 and the C-shaped connection portion 210 provided in one side of the toothbrush handle unit 200 in a corresponding manner.
