Description

[Detailed Description of the Invention] This invention relates to an improvement of a beating device used for hitting parts of the body such as shoulders to relieve stiffness.

As the above-mentioned beating device, one in which a beating body is provided at the tip of a handle whose base end is fixed to a grip is generally used, but the beating body has only one type of hardness.

However, it is desired to use hitting bodies with different hardnesses depending on the part to be hit, the user's preference, and the degree of stiffness of the shoulder or the like.

The object of this invention, in response to the above-mentioned demands, is to provide a hammer for hitting the shoulder, etc., in which the hardness of the part of the hitting body that comes into contact with the body can be changed into three types.

An embodiment of this invention will be described below with reference to the drawings.

In the figure, reference numeral 1 denotes a grip, to which the base end of a handle 2 is fixed.

This handle 2 has piano wires 4, 4 extending along the widthwise center of both sides of a thin flat plate 3 made of spring steel, and covered with a soft synthetic resin tube 5.

Attachment A8a by tightening the nuts 7 to the threaded portions 6a of the attachment pin 6 on both sides of the tip of the handle 2.

8b is fixed.

A first soft hitting body 9 made of a soft air-filled rubber ball is adhered to the tip end-surface fitting 8a of the handle 2.

A second hitting body 10, which will be described later, is attached to the tip 6b of the attachment pin 6 that protrudes from the attachment 8b on the other side of the tip of the handle 2.

The second hitting body 10 is formed by baking or adhering a hard part 10a made of an elastic material such as rubber having a hardness of 55 to 60 degrees and a medium part 10b made of an elastic material such as rubber having a hardness of 35 to 50 degrees. Laminated in the axial direction.

The hard part 10a has a hemispherical outer end and a thickness of the medium part 10.
The middle part 10b is also thick, and the outer end of the middle part 10b is formed into a planar shape perpendicular to the axial direction, and the hard part 10a and the middle part 10b are colored in different colors.

The second beating body 10 has both hard and medium parts 10a and 1.
A hole 10c is formed that passes through the center of 0b in the axial direction,
The distal end portion 6b of the mounting pin 6 is press-fitted halfway into the hole 10c so that the hard portion 10a and the medium portion 10b can be installed with the hard portion 10a and the medium portion 10b reversed.

With the above structure, hold the grip 1 and place your shoulder on the 1st grip. Loosen the stiffness by hitting with one side of the second hitting body 9.10.

In this case, the hard part 10a of the second hitting body 10 is brought into contact with the shoulder at the beginning of use when the stiffness of the shoulder is severe, and after the stiffness of the layer is loosened to some extent, the medium part 10b is brought into contact with the shoulder. In this way, the second striking body 10 can be reversed and attached to the mounting pin 6 for replacement, and the soft first striking body 9 can be used at the end of use.

Depending on the preference of the user, either the hard part 10a or the medium part 10b of the first hitting body 9 or the second hitting body 10 can be used to hit the shoulder or the like.

Furthermore, the body part other than the shoulder can be hit in the same way as the shoulder, and in this case, when hitting the soft part of the body, the soft first hitting body 9 and the second soft hitting body 10 are used. Massage part 10
It is preferable to use b.

Since the mounting pin 6 is only fitted halfway into the hole 10c of the second striking body 10, not only does the user not feel the hardness of the mounting pin 6 when using it, but also the The elastic deformation of the second hitting body 100 causes an adsorption action due to reduced pressure, which improves blood circulation.
This is noticeable when applying it to the body.

In addition to this invention, a rubber sponge or the like may be used as the first hitting body instead of the air-filled rubber ball.

As explained above, according to this invention, the hardness of the part of the hitting body that comes into contact with the body can be changed to three types, hard and soft, depending on the part being hit, the stiffness of the shoulders, etc., and the user's preference. As a result, it is possible to perform comfortable and effective shoulder clapping.
