Description of the Related Art Generally, various brushes such as toothbrushes, shoe brushes, clothes brushes, cleaning brushes and polishing brushes form a groove or a hole in a substrate, and the groove or the hole is formed in the groove or the hole. It has a structure in which the brush core is fixed.

[0003]

However, the conventional brush as described above has no problem in brushing a flat surface, but in the case of brushing an uneven surface which is not a flat surface. Brushing on uneven parts does not work. Therefore, it is common to bend the brush forcibly to polish or clean the uneven surface.In that case, not only the part of the brush core is easily damaged or worn but also the protruding part of the uneven part is It was caused that friction was intensively generated and only the protrusion was worn. In particular, when the toothbrush has a curved surface which is not flat like a human tooth, the conventional toothbrush is only easily worn, and the tooth surface cannot be uniformly brushed and cleaned.

Therefore, the object of the present invention is to solve the problems commonly possessed by various conventional brushes, and to clean all the uneven surfaces regardless of the state of the uneven surfaces when cleaning or polishing the uneven surfaces. An object of the present invention is to provide an elastic brush that can be uniformly brushed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in more detail with reference to the accompanying drawings showing the embodiments of the present invention thus configured. First, the brush can be made of various different materials according to the purpose of use. For example, brush cores made of materials such as natural animal hair, synthetic resin, metal, etc. are properly collected and arranged according to the usage conditions.

FIG. 1 is a schematic perspective view showing a brush of this type according to an embodiment of the present invention with a part cut away. In FIG. 1, reference numeral 1 indicates a brush core. At the lower end of such a brush core 1, the brush core 1 is joined to a roughly disc-shaped support piece 2, and the support piece 2 to which the brush core 1 is joined is formed into a plurality of holes ( Insert into the blind hole 4 freely. In this case, before inserting the support piece 2 into the hole 4, first, the spring 5 having elastic force is arranged in the hole to apply the elastic force to the support piece 2. Therefore, the brush core 1 advances or retracts according to the state of the surface to be brushed with which the tip portion contacts, that is, according to the external pressure received at the tip portion, and when the external pressure is removed, the elastic force of the spring 5 is released. Will return to the original position.

As described above, the coil spring is used as the elastic means which is provided below the support piece 2 and applies the elastic force to the support piece 2. However, various elastic means other than the coil spring can be provided. A spring in the form of can be used. Also, the degree of elastic force of the spring depends on the purpose of use of the brush, for example, cleaning, strong polishing, etc.
Alternatively, an appropriate degree may be selected and used depending on the material of the brush.

Now, in order to limit the forward movement position of the support piece 2 which receives the elastic force of the spring 5 from below, the hole 4 of the base body 3 is limited.
On the inlet side of, the cover 7 formed with a plurality of guide holes 6 having a diameter smaller than the diameter of the support piece 2 in conformity with the positions of the holes 4 of the base body 3 is fixed to the upper part of the base body 3. 2 is configured so as not to separate from the hole. Therefore, as shown in the cross section of FIG.
The support piece 2 is movably positioned inside the hole 4 of the base body 3 because the support piece 2 penetrates through the guide hole 6 formed in the base plate 3 and is projected to the outside. As a result, each brush core 1 moves back and forth while receiving elastic force according to the shape of the contact surface with which the tip of the brush core contacts. The holes may be formed in a groove shape.

FIG. 2 shows a second embodiment of the present invention.
Although the basic structure is the same as that of the embodiment of FIG. 1, in FIG. 1, the spring 5 and the brush core 1 are inserted into the hole 4 of the base 3 and then the cover 7 is fixed to the upper surface of the base. On the contrary, in the case of the embodiment shown in FIG. 2, first, a plurality of circular cylindrical holes 4a are integrally formed in the base body 3, and the brush core 1 and the spring 5 fixed to the support piece 2 are inserted into the holes 4a. After that, the cover 7 is fixed to the lower surface of the base body so as to cover the circular cylindrical hole 4a. The hole diameter of the circular cylindrical hole 4a on the brush core 1 insertion side is formed to be smaller than the diameter of the support piece 2 so that the brush core 1 and the support piece 2 are not separated from the base body 3. Such an embodiment can be appropriately modified and implemented according to the purpose of use of the brush or the work process.

[0012]

As described above, the elastic brush of the present invention does not directly fix the brush core to the groove or hole of the brush base like the conventional brush, but the tip of the brush core contacts. Since the brush core is configured to be movable according to the contact surface to be contacted, it is possible to apply the brush uniformly while applying a constant pressure to the friction surface regardless of the shape of the uneven surface. The friction surface can be uniformly cleaned or polished without being easily worn or severely worn at a predetermined portion of the curved surface. Taking one toothbrush as an example, when using the toothbrush to which the present invention is applied for cleaning the tooth surface, it can contribute to the health of the teeth, which is very important for humans, and the time to apply the toothbrush can be saved according to the improvement of the brush performance. As a result, the life of the toothbrush is extended. Such an elastic brush of the present invention has a wide range of brushes of all forms for polishing or cleaning an object having a three-dimensional surface with severe bending, regardless of the use of the brush such as a cleaning brush and a polishing brush and the material of the brush. Can be used for As a result of cleaning and polishing the curved surface of the brush manufactured according to the present invention and the conventional brush, it was confirmed that the performance was improved about three times as much as that of the conventional brush.
