TECHNICAL FIELD The present invention mainly relates to a roller-type health appliance for applying an external stimulus to the fascia and realizing fascia release.

Conventionally, in order to alleviate symptoms such as stiff shoulders, lower back pain, or muscle pain, it is possible to perform a massage by oneself using fingers or a rounded shiatsu stick, or receive treatment at an osteopathic clinic or a massage parlor. was commonly done.

Especially in recent years, we focused on the fact that twisting, contraction, and adhesion of the fascia, which wraps the muscles and stretches throughout the body, causes stiffness and pain, and impairs the flexibility of the muscles. So-called myofascial release, which aims to improve muscle flexibility, expand the range of motion of joints, and improve blood circulation by unraveling the muscles, is attracting attention.

However, if you do it with your own fingers, the area you can reach is limited, so there are limits to where you can release the myofascia and the strength. Roller-type (pipe-shaped) fitness equipment is gaining popularity as a means for easily relieving muscle stiffness and pain.

For example, as shown in JP-A-2004-305232 (Patent Document 1) and JP-A-2010-22729 (Patent Document 2), a pipe-shaped health appliance made of a rigid material is known. Further, as a commercially available product, a product having a large number of irregularities formed on the outer peripheral surface is also known.

When using these pipe-shaped health appliances, the pipe-shaped health appliance is rolled on the floor, and a person puts his or her back or waist on it and lies on his/her back. It reciprocates, stretches the back and hips, and stimulates the fascia and muscles.

In addition, there is known a spherical health appliance for fascia release having elasticity, as disclosed in Japanese Patent Application Laid-Open No. 2019-80725 (Patent Document 3).

When using these spherical health appliances, hold the spherical health appliance in your hand and press it against the affected part such as the shoulder or neck, or hold it between the wall or floor and the body, and roll the spherical health appliance to reciprocate. This directly stimulates the affected area such as the shoulder and neck to stimulate the fascia and muscles.

However, these conventional pipe-shaped and spherical health appliances have a wide range of action in the pipe-shaped health appliance and disperse the stimulus to the fascia, Since there are limits to the positions and angles that can be acted upon when used in between, it is difficult to give a strong or deep stimulation to the desired specific part of the human body, and a sufficient effect of myofascial release is achieved. It was difficult.

Preferred embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view showing a preferred embodiment of a roller-type health appliance 100 of the present invention, and FIG. 2 is a front view.

As shown in these figures, the roller-type health appliance 100 comprises a core portion 10 and a cushioning portion 20, and is used in combination with a ball B to give external stimulation mainly to the fascia of the human body. It is used to realize the release.

The core portion 10 is made of hard PVC (polyvinyl chloride), which is a hard material in this embodiment, and has a cylindrical shape with a predetermined inner diameter. Regarding the material, PVC is particularly desirable because it has appropriate hardness and elasticity, but other synthetic resins may be used as the hard material.

The cushioning portion 20 is made of EVA foam (ethylene-vinyl acetate copolymer), which is an elastic material in this embodiment, and is arranged to cover the outer periphery 11 of the core portion 10 . Regarding the material, EVA foam is particularly desirable because it has appropriate hardness and elasticity, but other synthetic resins may be used as the elastic material.

In this embodiment, the cushioning portion 20 is made of EVA foam having a hardness of 55 degrees and a surface hardness of 72 degrees. An improvement in the film release effect can be expected, but it is not limited to this, and it is also possible to use materials with higher or lower hardness.

A plurality of grooves 22 formed in the axial direction and a plurality of grooves 23 formed in the circumferential direction are formed in an outer circumference 21 of the buffer portion 20 . When the ball B is used without being combined with the ball B, the surface of the section is divided into irregularities, which stimulates the human body and exerts the effect of releasing the fascia.

An outer periphery 21 of the buffer portion 20 is formed with a recess 30 having a circular shape in plan view and a recess 40 having an oval shape in plan view. , 41 for receiving and holding a portion of said ball B. FIG.

In the production of the roller-type health appliance 100, the shock-absorbing portion 20 is formed by setting the pre-molded core portion 10 in a mold and then filling the mold with pre-hardened EVA foam. It is preferably manufactured by insert molding, but may be manufactured by other conventionally known methods.

FIG. 3 shows how the roller-type health appliance 100 is used.

As shown in this figure, when using the roller-type health appliance 100, the roller-type health appliance 100 is placed on the floor F, and a part of the ball B is placed in the recess 30 (or the recess 40). In the fitted state, the user U puts his/her weight in such a posture that the ball B protruding from the recess 30 (or the recess 40) hits the part P to be released with the fascia, and the part P is pushed by the ball B. It gives an external stimulus to

At this time, since the roller-type health appliance 100 can roll on the floor F, the user U rocks his or her body back and forth to move the body around the site P more deeply or strongly from various angles. Provides stimulation and myofascial release.

In this way, by using the roller-type health appliance 100 and the ball B in combination, the conventional pipe-shaped health appliance has a wide range of action and the stimulation is dispersed, while the conventional spherical health appliance has a wide range of action. Due to its small size, it is difficult to hold it in an appropriate position when it is sandwiched between the wall or floor and the user U. It stimulates the fascia of the body to release the fascia.

4 is a plan view of the roller-type health equipment 100, and FIG. 5 is a cross-sectional view taken along line AA of FIG.

6A and 6B are cross-sectional views of the main parts of the roller-type health appliance 100, FIG. It is a figure which shows the state which fitted a part of B.

As shown in FIG. 6(a), since the recess 30 has a circular plan view shape, the ball B is held on the entire surface of the inner circumference 31, and movement of the ball B in all four directions will eventually occur. is also restricted and cannot move.

Therefore, the user U presses the ball B projecting from the recess 30 against the desired part P in a stable state, and then rocks the body back and forth using the rotation of the roller type health appliance 100. By moving the ball B, it is possible to give various angles, depths, and strengths of stimulation from the ball B to the part P as compared with pressing the ball B in a stationary state. This recess 30 is used when it is desired to give stimulation to a particularly narrow range or a deep site.

As shown in FIG. 6B, since the recess 40 has an oval shape in plan view, the ball B is not held over the entire surface of the inner circumference 41, but in the width direction (shown in the drawing). Although the movement of the ball B in the up-and-down direction) is restricted, the movement of the ball B in the axial direction (the left-and-right direction in the figure) by a certain distance is kept possible.

Therefore, the user U presses the ball B projecting from the recess 30 against the desired part P in a stable state, and then rocks the body back and forth using the rotation of the roller type health appliance 100. By moving the ball B to the part P, it is possible not only to give a stimulus of various angles, depths and strengths, but also to move the body left and right. A rocking motion allows the ball B to press against the site P within the range of axial movement within the recess 40 and to provide further stimulation.

In this embodiment, the depth h1 of the recess 30 and the depth h2 of the recess 40 are shallower than the radius r of the ball B. Since most of B is exposed, it is easy to press the ball B against the portion P. may be designed in any range with the diameter of the ball as the upper limit.

In the present embodiment, the number of recesses is the same in the axial direction (horizontal direction in the drawing), one each of the recesses 30 having a circular shape in plan view and the recesses 40 having an oval shape in plan view. Although it is formed in a line, it may be formed in multiple numbers, and the shape of the recess is not limited to the circular or oval shape in plan view as described above, and may be an elliptical shape. (not shown).
