The exercise assistance tool of the present embodiment will be described with reference to the drawings. FIG. 1 is a perspective view showing the structure of the exercise assisting device. FIG. 2 is an explanatory diagram of comparison results such as a feeling of use in exercise assistive devices having various configurations.

As shown in FIG. 1, the exercise assisting tool 1 occupies a substantially cylindrical region in a cylindrical outer portion 11 having a soft outer shape made of a soft material having elasticity, and a central portion in the radial direction of the outer portion 11. A core portion 12 made of a material harder than the exterior portion 11 and a covering portion 13 provided so as to cover the outer surface 11a of the exterior portion 11 are provided.

In this embodiment, the exterior part 11 is formed in a cylindrical shape having an outer diameter of 125 mm, an inner diameter of 90 mm, and a length of 970 mm by a foamed urethane chip, and is formed thinner than a conventional exercise assisting tool (outer diameter of 150 mm). Yes. The foamed urethane chip is rich in flexibility and elasticity, and has the feature that the initial shape can be maintained over a long period of time, and can be suitably used.

The core part 12 is formed by a cylindrical core material 12a made of polystyrene beads and having an outer diameter of 90 mm, and a resin film 12b wound around the outer surface of the core material 12a. According to this structure, since the resin film 12b acts as a reinforcing material that reinforces polystyrene bead foaming, the core material 12a can be made of polystyrene bead foam that is low in strength but less expensive than polyethylene or polypropylene bead foam. . Here, if the core portion 12 can be reinforced, a coating layer of resin or rubber can be used instead of the resin film 12b. When the core material 12a is formed by foaming polyethylene or polypropylene beads, the resin film 12b may not be used.

The covering portion 13 is configured as a cover material made of polyvinyl chloride that covers the outer surface 11 a of the exterior portion 11. By providing the covering portion 13, moisture and the like can be blocked from the exterior portion 11, so that weather resistance can be improved. Moreover, the intensity | strength of the exercise assistance tool 1 can be improved by restraining the exterior part 11 from the surface. Furthermore, by applying a surface treatment to the covering portion 13, it is possible to improve the antibacterial properties and to prevent contamination.

Since the exercise assistance tool 1 has the above-described configuration, the following effects can be achieved. First, since the exterior part 11 is formed of a soft material, the repulsive force on the body when riding on the exercise assisting tool 1 is reduced, and the user can obtain a soft feeling of use.

Further, since the core portion 12 is made of a material harder than the exterior portion 11, the ease of rolling on the exercise assisting device 1 is sufficiently secured, and the effect of improving the pelvic distortion and the range of motion of the ribs are improved. Since the rolling characteristics that are important for these are good, the exercise effect can be enhanced.

Furthermore, the exercise assisting device 1 is formed thinner than the conventional exercise assisting device, has a low height from the floor surface during use, and the exterior portion 11 is formed of a soft material. It is easy to get on the assisting device 1 and can be used effectively and safely even for elderly people, patients with problems in balance ability, and users with short stature.

Since the exercise assisting device 1 is flexible and easy to bend, the exercise assisting device 1 can be used in an easy posture by bending the exercise assisting device 1 on a chair back or on a bed in an elderly facility or the like.

Due to the above-described effects, the exercise assisting device 1 can be used as an exercise assisting device having a high exercise effect that can be used with peace of mind without a large burden on users such as hospitals and care facilities, elderly people, and non-healthy people.

The exercise assisting tool 1 is preferably formed to have a diameter of 100 to 150 mm. When the diameter is less than 100 mm, the body muscles and tendons cannot be sufficiently relaxed, and sufficient exercise effects cannot be obtained. On the other hand, when the diameter exceeds 150 mm, the height from the floor surface becomes high and it is easy to roll. Therefore, for elderly people and patients who have problems with balance ability, the instability causes whole body tension. Therefore, a sufficient exercise effect cannot be obtained.

Moreover, it is preferable that the core part 12 is formed so that a diameter becomes 20 mm or more smaller than the diameter of the exterior part 11. According to this structure, since the exterior part 11 made of a soft material is formed with a sufficient thickness, the user can obtain a soft and appropriate feeling of use.

The exterior portion 11 may be any material that is soft against the human body and rich in elasticity. For example, a fiber-based elasticity such as foamed rubber, urethane foam, polyethylene foam, ethylene-vinyl acetate copolymer resin foam, filter felt, and the like. Materials, cotton materials, etc. can be used. The hardness of the exterior portion 11 is preferably about 5 to 35 degrees in the sponge hardness (Asker C) described in the Japan Rubber Association Standard SRIS 0101, for example.

Moreover, the core part 12 should just be comprised with the material harder than the exterior part 11, and can use various materials. For example, various resin materials such as polyvinyl chloride, polyethylene, polypropylene, elastomer, and polyethylene terephthalate, rubber, wood, metal material, paper-based material, and the like can be used. Among these, a flexible material can be used more suitably.

The exterior part 11 or the core part 12 should just be harder than the exterior part 11 whole as the core part 12 whole. For example, a material formed by laminating a plurality of layers in the diameter direction, or a gradient material that hardens toward the center direction can be used. Moreover, the hard core part 12 may be formed by forming the exterior part 11 and the core part 12 from the same material and increasing the density in the vicinity of the center part. Here, when hardness changes continuously from the exterior part 11 to the core part 12, the area | region more than predetermined | prescribed hardness is called the core part 12. FIG. For example, a region having a hardness that is twice or more the hardness of the outer surface of the exterior portion 11 can be defined as the core portion 12.

The core part 12 does not need to be formed to the same length as the exterior part 11, and may be formed so as to be wrapped by the exterior part 11 in a part of the longitudinal direction of the exterior part 11.

The covering portion 13 can also be configured to be separable from the exterior portion 11. According to this configuration, cleaning and replacement can be easily performed when the covering portion 13 is soiled. The covering portion 13 may be formed by coating the outer surface of the exterior portion 11 with resin or rubber, or may be formed by winding with various film materials.

Comparison results such as feeling of use in exercise assistive devices having various configurations will be described with reference to FIG. As the material of the exterior part 11, four types of ultra-high density chip foam, high density chip foam, high density urethane foam, and medium density urethane foam were used in the order of hardness. As the material of the core portion 12, two types of high hardness foamed polystyrene and medium hardness foamed polystyrene were used in the order of hardness. The diameter of the exterior part 11 was fixed to 125 mm, and the diameter of the core part 12 was set to three levels of 80, 90, and 100 mm. The evaluation was performed on three items: hardness felt at the time of use, ease of exercise, and ease of riding on the exercise assisting tool 1, and the mark “◯” was judged to be good. The evaluation results are as follows: F, H, I, J, K, and L were good. In particular, in the configuration in which the diameter of the core 12 was 90 mm, all were judged to be good. From the above, good evaluation is obtained in the exercise assisting tool 1 having a diameter of the core 12 of 80 to 100 mm, and 90 mm is particularly preferable.
