DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of the present invention will be described.
The present invention will be described in detail.First embodiment  FIG. 1 shows a schematic view of an embodiment of the shock absorber of the present invention.
You. The cushioning device 2 shown in FIG.
The container 4 formed as described above and the container
Buffer par consisting of flowable substance 6 filled in 1/3 amount
And a bell for attaching the cushioning part 8 to the body
10, 12, and 14.

The elastic material of the container 4 forming the buffer part 8 in the present invention includes natural rubber, polyurethane, vinyl, nylon, sponge and the like. In this embodiment, the container 4 is formed using nylon or vinyl. The belts 10, 12, and 14 are for attaching the cushioning parts 8 to the body. In the present embodiment, the belts 10 are attached to the waist to attach the cushioning parts 8, and the belts 12 and 14 use the thighs of the cushioning parts. Covering portions 16 and 18 for covering the greater trochanteric portion
By wrapping both the tip and the leg around the leg, it is designed to be snugly attached to the body.

The cushioning device of the present invention is characterized in that the cushioning part 8 covers at least the greater trochanter of the two feet when worn on the body with the belts 10, 12, 14 according to such a configuration. . The form of the belts 10, 12, and 14 is not particularly limited, and may be any as long as the buffer parts can be suitably worn on the body. Therefore, as a material of the band, a material used for a general band can be applied, and leather, vinyl, plastic, resin, and the like can be used, but there is a difference in fit even if a wearer has a different body shape. Make sure that the band material has elasticity so that it does not come out.
It is preferable that it can be fixed by such means.

In the present invention, the flowable substance 6 filled in the buffer part 8 is filled in an amount of ２〜 to １ ／ of the total volume of the container 4. This is because the fluid material 6 moves to the covering portions 16 and 18 by fixing the cushioning parts with the band, and the amount of the fluid material 6 filled in the covering portions 16 and 18 substantially absorbs impact. This is because the amount is adjusted to be sufficient.

[0016] With such a configuration, since an excessive amount of the fluid substance is not filled, the weight of the shock-absorbing device of the present invention can be reduced. Also, when walking or standing upright, tighten the belt so that the covering part of the buffer part is filled with sufficient fluid material, exhibit sufficient cushioning effect when falling, and loosen the belt when sitting or lying down The feeling of use can be easily adjusted by the tightening strength of the belt so that the feeling of oppression and discomfort can be reduced.

In the cushioning device of the present invention, the amount of the fluid substance to be filled is determined by the amount of the covering portion 1 when worn on the body.
It is preferable that the shock absorption ratios of Nos. 6 and 18 are adjusted to be 40% or more, and more preferably 50% or more. Further, the shapes of the covering portions 16 and 18 are curved so as to exactly fit the line from the waist to the leg of the human body.

FIG. 2 is a sectional view for explaining the shapes of the covering portions 16 and 18. As shown in FIG. In this figure, parts corresponding to the same components as those in FIG. 1 are denoted by the same reference numerals, and description thereof is omitted. As shown in FIG.
Reference numerals 6 and 18 each have a curved shape so as to be substantially the same as the line from the waist to the leg of the human body. Note that such a line has individual differences depending on the wearer. As described above, the buffering tool of the present invention is such that the container forming the buffer part is filled with the flowable substance, and the belt 10 is tightened when the buffer part is mounted, so that the liquid substance is stored in the container as shown by the arrow. Although it moves inside and is filled into the covering portions 16 and 18, even though the shape of the covering portions 16 and 18 is attached, even if the line is slightly different from the line from the waist to the legs, the flowable substance is filled. Accordingly, it can be deformed into a shape that fits perfectly to the body. In this way, the covering portions 16 and 18 are filled with the flowable substance by mounting the belt,
Even if there is an individual difference in the body shape, since the covering portions 16 and 18 are deformed so as to fit the body while being filled with the fluid substance, it is possible to cancel the individual difference in the body shape and properly fit. It becomes possible.

In the shock-absorbing device of the present invention, a plurality of elastic projections are formed at least inside the covering portions 16 and 18 of the container forming the shock-absorbing parts. The protrusion 20 may be formed of the same material as the elastic material forming the container, or may be formed of a material having more preferable physical properties.

When the shock absorber of the present invention is mounted and falls down, the impact force can be reduced by the shock absorbing parts. However, if a part of the container is damaged, the flowable substance flows out of the container and does not exhibit a buffering action. Such a situation is assumed not only when a strong impact exceeding the durability of the container is applied due to the fall, but also when a part of the container is damaged by a sharp object unintentionally. In such a case, the buffer effect may not be exhibited at all in an emergency.
In this way, even if the container is damaged and the fluid substance filled therein flows out due to an accident, the impact on the body can be prevented to some extent.

For this reason, the shape of the projection 20 is not particularly limited, such as a columnar shape or a polygonal columnar shape, but is at least as thick and higher than a cylindrical shape having a diameter of 5 to 10 mm and a height of 5 to 10 mm. Is preferably 20 mm to 30 mm. If the diameter and height of the projections are less than this, a sufficient preventive cushioning effect cannot be obtained. Similarly, if the distance between the projections is larger than this, a sufficient preventive buffering effect cannot be obtained. When worn on the body with the belt as in the embodiment of the shock absorber of the present invention shown in FIGS. 1 and 2,
It is preferable that the cushioning part covers the coccyx as well as the greater trochanter of the femur of both feet.

A fall may cause stickiness. In such a case, not only the tailbone may be damaged by the stickiness but also the spine and the tibia may be damaged by an impact applied to the tailbone. Therefore, the cushioning parts are provided together with the greater trochanters of both feet together with the coccyx covering part 2.
If the structure 2 covers the coccyx, the shock applied to the coccyx can be softened.

In the shock-absorbing device of the present invention, the fluid substance to be filled in the container forming the shock-absorbing part includes:
It is preferably a gas such as nitrogen, carbon dioxide, helium or the like, and more preferably air. By using such a fluid substance, the cushioning device of the present invention can be reduced in weight and the production cost can be suppressed.

A gel substance can be used as the fluid substance. Examples of such a gel-like substance include various polymers, and among them, a superabsorbent polymer (polymerized polyvinyl pidridone) is preferable. By using a gel-like substance as such a fluid substance, a high buffering performance can be imparted to the buffering tool of the present invention, and it is possible to manufacture the buffering tool at a relatively low cost. In the cushioning device of the present invention, the flowable substance filled in the container forming the buffer part is provided with a pillar entrance in a part of the container so that the filling amount can be adjusted according to the body shape of the mounted one. Such a configuration may be adopted.
