Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a pine surgery tool for pine surgery by hitting the scalp, etc.

"Problems to be solved by conventional techniques and ideas" Generally, when performing pine surgery by hitting the scalp, etc.
This was done using a hair brush with rather thick and hard bristles.

However, the above-mentioned brush bristles had the disadvantage that they were too sharp and the impact was too strong, making them difficult to use, especially for people with little hair. Incidentally, it is said that the best way to treat pine surge is to feel it with your fingertips.

Therefore, conventional methods have been proposed in which a spring is interposed in the upper part of the handle to which the brush stand is connected to elastically support the brush stand, thereby attempting to buffer the above-mentioned impact as much as possible. However, this was still unsatisfactory because the sharpness caused by the material of the brush bristles did not change in any way.

Therefore, an object of the present invention is to provide a highly practical pine surge tool that can effectively provide a pine surge sensation similar to the fingertips of the hand.

"Means for solving the problem" In order to achieve the above purpose, the present invention has a handle part 1.
A guide cylindrical portion 8 with an open rear end extends rearward from the rear surface of the base 7 attached to the upper end, and a spherical weight 11 is rotatably housed in the cylindrical portion to open the rear end of the cylindrical portion. It is characterized by being closed by a cap-shaped portion 4 and having a plurality of elastic protrusions 16 protruding from the front surface of the base.

``Operation'' For example, hold the pine surge tool in the state shown in Figs.
6 collides with the scalp or the like, the elastic protrusions 16 produce a pine surge sensation similar to a blow with the fingertips of a hand.

In addition, at this time, the spherical weight body 11 inside the guide cylinder part 8
rolls backward in the cylindrical part 8 as the base 7 moves forward, and when the elastic protrusion 16 collides with the scalp etc., the cylindrical part 8 rolls forward due to inertia and the base 7 Collision with the rear.

The impact force at this time is transmitted to the elastic protrusions 16, and as a result, the impact force exerted by the above-mentioned elastic protrusions on the scalp etc. is further increased. In other words, a large impact force can be obtained with a small swing.

It goes without saying that the impact force described above can be changed by selecting steel, resin, or the like as the material of the spherical weight body 11 and varying its mass.

"Embodiments" Examples of the present invention will be described below based on the accompanying drawings.

1 and 2 show a first embodiment of the pine surge tool of the present invention, in which a jagged gripping portion 2 is formed at the lower part of both the front and rear sides of the handle 1, and the gripping portion 2 A through hole 3 is provided in a protruding manner at the lower end portion thereof.

A cap-shaped part 4 of the opening is integrally installed horizontally at the upper end of the handle part 1, and a peripheral wall 5 of the cap-shaped part
A female threaded portion 6 is carved on the rear inner surface.

A guide cylinder part 8 with an opening at the rear end extending rearward from the center of the rear surface of the disc-shaped base 7 is inserted into the peripheral wall 5a of the cap-shaped part 4, and the outer tip of the guide cylinder part 8 is inserted into the peripheral wall 5a of the cap-shaped part 4. A male threaded portion 9 is threaded into the female threaded portion 6. Therefore, the rear end opening of the guide cylinder section 8 is closed by the top wall 5b of the cap-shaped section. In the illustrated example, a buffer plate 10 made of a soft material is sandwiched between the rear end surface of the guide cylinder part 8 and the top wall of the cap-shaped part 4.

A spherical weight body 11 is housed within the guide tube portion 8 so as to be able to roll freely in the axial direction of the tube portion. In the illustrated example, one spherical weight body 11 is stored, but a plurality of spherical weight bodies 11 may be stored.

An elastic cylinder 12 made of rubber is attached to the base 7.

The elastic cylindrical body 12 has a cylindrical wall 14 fitted onto the outer circumferential surface of the base 7 via an engaging means 13 of uneven stripes.
The cylindrical projections 16 extend rearward from the peripheral edge of the front wall 15, and a plurality of (eight in the figure) cylindrical projections 16 integrally project from the front surface of the front wall 15 at equal intervals in the circumferential direction. In the illustrated example, the top wall portion of the cylindrical projection 16 is formed into a hemispherical shape.

In the figure, reference numeral 17 is an annular recess formed on the outer periphery of the front surface of the base 7 to reduce the thickness of the base.

Therefore, in the present invention, by changing the degree of screw engagement between the guide cylinder part 8 and the cap-shaped part 4, the stroke (i.e., the momentum) of the spherical weight body 11 can be changed, and thereby the stroke (i.e., the momentum) of the spherical weight body 11 can be changed. The striking force can also be variably adjusted.

Next, FIGS. 3 and 4 show a second embodiment of the pine surgery tool of the present invention.

This is an example in which the base 7 and the guide cylinder part 8 in the previous embodiment are formed integrally with the handle part 1 via the bifurcated part 18, while the cap part 4 is formed separately from the handle part 1. , its operation and effect are the same as those of the previous embodiment.

In both of the above embodiments, each part except the elastic cylinder 12 and the buffer plate 10 is molded and manufactured from a suitable synthetic resin material.

"Effects of the Invention" As explained above, according to the present invention, since the impact is made by the elastic protrusion, a pine surge sensation similar to the fingertips of the hand can be easily obtained. In addition, the impact force generated by the elastic protrusion is greatly increased by the impact force generated when the spherical weight collides with the base, so a large impact force can be obtained with a small swing, and the material of the spherical weight Depending on the selection, the above-mentioned impact force can also be variably adjusted, which is extremely convenient for use.
