Abstract

PROBLEM TO BE SOLVED: To provide a shock-absorbing clothing material, light in weight, easily deformed to ensure freedom in wearing, excellent in air permeability and shock absorbing properties and useful for various sports matches by constituting the material in a three-dimensional shock absorbing structure having three- dimensional cross-linked ribs. SOLUTION: This shock-absorbing clothing material is constituted of a three- dimensional shock-absorbing structure 3 having a three-dimensionally cross-linked ribs 1 by integrally forming a synthetic resin having an appropriate plasticity and elasticity in longitudinally and latitudinally crossing lattice-like form, e.g. a longitudinal and latitudinal, a diagonal, a honey comb or an arrow-feather lattice-like form, in a ribbon-like state having an appropriate thickness and rectangular cross section in a predetermined space. It is preferable to laminate a base fabric 6 having air permeability and flexibility along at least one side of the three-dimensional shock-absorbing structure 3 during its knitting or adherently laminate the base fabric by an insert molding during the formation of the three-dimensional shock-absorbing structure or by simply adhering the base fabric thereon.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shock absorbing garment for use in various sports, and more particularly to a shock absorbing garment material having improved air permeability and cushioning.

[0002]

2. Description of the Related Art Various types of protectors and shock-absorbing clothing suitable for each sport have been used in automobiles, cycling or other various sports for the purpose of protecting the body from accidents such as collisions.

[0003]

However, if the cushioning force is increased to protect the body, the amount of deformation of the material is reduced and the degree of freedom is impaired, so that there is a tendency to dislike wearing. In particular, it has the drawback of impairing the air permeability essential for sports competitions involving sweating. There is also a problem that players who do not wear the protector do not disappear.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and has an excellent air permeability, a sufficient cushioning ability in a thickness direction, a light weight, easy deformation, and a high degree of freedom when worn. It is an object of the present invention to provide a shock absorbing garment material having a novel structure that can be used.

[0005]

The shock absorbing garment material according to the present invention is made of a synthetic resin having appropriate plasticity and elasticity to form a ribbon having a suitable thickness into a lattice shape which crosses vertically and horizontally at predetermined intervals and obliquely as required. The gist is to form a three-dimensional shock-absorbing structure with three-dimensional cross-linking ribs, and if necessary, it is located at each lattice-shaped intersection and has the same width as the ribbon. Alternatively, a columnar small block longer than the width can be integrally molded to adjust the shock absorbing force.

[0006] A breathable and flexible fabric base fabric knitted at the time of mesh knitting is laminated side by side on at least one side of the three-dimensional shock absorbing structure, or insert molded at the time of forming the three-dimensional shock absorbing structure. The gist is that they are fixed and laminated by adhesion.

In addition, at least one side of the three-dimensional shock absorbing structure is provided with a plurality of small holes perforated and arranged at appropriate intervals in a plate material having an appropriate thickness made of a flexible soft synthetic resin foam material. Either an elastic base material is laminated in a side-by-side manner, a two-color molding or adhesively fixed lamination is performed at the time of forming the three-dimensional shock absorbing structure, or at least a part of the three-dimensional shock absorbing structure is fitted to the perforated elastic substrate. This is a laminated shock absorbing garment material having a fitted laminated structure.

Further, a laminated type shock absorbing garment material having a multi-layered structure in which the three-dimensional shock absorbing structure and the perforated elastic base material are alternately stacked side by side can be provided.

[0009] The shock absorbing garment material having the above-mentioned structure is characterized in that a three-dimensional shock absorbing structure made of a soft resin or a three-dimensional shock absorbing material is formed on a surface of a cloth base fabric or a perforated elastic base material by forming a large number of air passages perpendicular to the surface. It is configured to form.

For this reason, the shock absorbing garment material has a structure that does not hinder the flow of air flowing from the front side to the back side or the reverse direction over the entire surface of the shock absorbing garment material. Due to the flexibility, air movement is forcibly performed by the bellows action accompanying the exercise, and the temperature environment of the body surface of the wearer can be improved.

Further, with respect to the impact in the thickness direction, the three-dimensional shock absorbing structure constituting one layer absorbs the deformation and breaking energy due to the buckling or cutting of the three-dimensional bridge rib. In the case of a structure in which perforated elastic substrates are juxtaposed, the impact is absorbed by the two-stage absorption in which the impact energy is absorbed by the deformation energy accompanying the plastic deformation due to the collapse of the perforated elastic substrate. Exerts a sufficient absorption and protection effect.

When the shock-absorbing pad is sewn with the above-described shock-absorbing garment material, the shock applied to the body at the time of the accident can be protected by the above-described two-stage absorption, the breathability is ensured, and the mobility is improved. Can also be guaranteed.

It is made of synthetic resin and molded from synthetic resin such as silicone rubber or urethane rubber. The ribbons of thickness and width are integrated into a 60 ° grid that crosses vertically and horizontally and diagonally at an angle of about 60 ° at regular intervals. Molded,
