DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an acupressure device having a flexible arm for manually applying a massage effect or an acupressure effect to the muscles on the back of a human body, particularly on both sides of the spine, and more particularly, to an acupressure device provided with a convex circumferential surface. It relates to a cylindrical back acupressure device with a manual flexible arm.

[0002]

2. Description of the Related Art Conventionally, a cylindrical back acupressure provided with a convex peripheral surface which gives a massage effect or acupressure effect to the back of the body by moving the acupressure device by hand or by moving the back of the body on the acupressure device. The vessel is, for example,
As described in Japanese Patent Application Publication No. 100033, a roller having a single rod and a grooved roller is a roller having a groove at the center of a grip bar having a size that can be gripped by hand. This is a cylindrical acupressure device. A method of using such a cylindrical acupressure device is that, for example, a person who intends to perform acupressure lies down on his / her body on a gripping bar having the cylindrical acupressure device, and hands with both ends of the gripping bar behind. Acupressure or massage is performed by moving the body up and down while pressing and holding the ridge of the cylindrical acupressure device against the back while holding and holding, or moving the body up and down while pressing the back against the cylindrical acupressure device. However, many people who require acupressure do not move their back hands sufficiently well in the head direction, which limits the range of acupressure on their backs to a significantly reduced range. There was a problem that the back could not be fully shiatsu.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned conventional problems, and to provide a cylindrical acupressure device on the head direction side where acupressure is required without moving the back hand largely in the head direction.

It is a cylindrical back acupressure device 1 with an arm.

According to the second aspect of the present invention, the cylindrical body 2 can rotate around the rotating shaft 23 of the back bar 29. It can be easily moved up and down between the sides, and in this case, it is easy to apply weight to the cylinder 2 and massage the back while rotating the cylinder 2.

According to the third aspect of the present invention, the convex peripheral surface 3 composed of a large diameter portion and the concave peripheral surface 4 composed of a small diameter portion are continuously curved in the axial direction 6 so that a concavo-convex neck 5 is formed on the peripheral surface. The formed cylindrical body 2 is a cylindrical body 2 having both ends of the cylindrical body 2 as a convex peripheral surface 3 having a large diameter portion and a central portion as a concave peripheral surface 4 of a small diameter portion. Item 3. A cylindrical back acupressure device 1 with a flexible arm according to the means of item 1 or 2.

According to the third aspect of the present invention, the convex peripheral surface 3 composed of the large diameter portion is located on both ends of the cylindrical body 2 and the central portion is the concave peripheral surface 4 composed of the small diameter portion to form the constriction 5. Therefore, it is possible to apply acupressure or massage by pressing the tendons on both sides of the spine without compressing the spine.
