[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cup-shaped stabilizer used for shoes, wherein the bottom and the wall are integrally formed in a continuous cup shape corresponding to the shape of the heel of the human body. The present invention is particularly effective for use in sports shoes.

[0002]

2. Description of the Related Art Protective equipment called stabilizers are frequently used in shoes, particularly sports shoes. This stabilizer is provided between the instep cover and the midsole for protection of the heel part or between the instep cover and the sole, and is disclosed in Japanese Utility Model Publication No. 63-10726 and Japanese Utility Model Publication No. 2-4573. The stabilizer is generally designed to prevent sideways sway of the heel and absorb and reduce the impact of landing during running and the impact of level crossing when jumping. It is formed by an injection method using a mold, although there are various molding means, and the synthetic resin used is nylon resin, PVC resin, polyurethane resin, or other resin having elasticity and rigidity. It was used but could not yet be satisfied. In order to alleviate the stress applied to the heel portion, there has been proposed a stabilizer formed in a cup shape having a bottom surface provided at a stepping portion of a horseshoe-shaped stabilizer.

[0003]

The cup-shaped stabilizer is required to be as thin as possible in order to eliminate a feeling of discomfort during use and to reduce the weight. However, when formed to be thin, the elasticity and rigidity are insufficient, so that there is a problem that it is not possible to absorb an impact during use. In order to solve this problem, a cup-shaped stabilizer formed of a fiber reinforced resin using glass fiber or carbon fiber woven fabric, nonwoven fabric, short fiber chip or the like as a reinforcing material has been provided, but still satisfactory ones have been obtained. There is no situation.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention utilizes a shape memory alloy mesh material utilizing the material characteristics of a shape memory alloy having excellent elasticity and rigidity and excellent shape shapeability. An object of the present invention is to solve the above problem by using a cup-shaped stabilizer formed by using a board or a nonwoven board as a reinforcing material of a synthetic resin. The shape memory alloy material used in the present invention is arbitrary, but a mesh plate or the like formed of a thin wire of a Ti—Ni alloy is preferable, for example.

[0006] First, a mesh plate made of an arbitrary shape memory alloy is cut to form a reinforcing material whose shape has been previously memorized into a desired shape, and the reinforcing material is arranged in a molding die. A description will be given of an embodiment of a cup-shaped stabilizer in which a synthetic resin is injected and injected into the inside and a reinforcing material and the synthetic resin are integrally formed. Mesh plate 2 made of any shape memory alloy
Can be formed continuously on both sides of the bottom 4 with the wall 5
The mesh plate is cut into a predetermined shape, the shape of the mesh plate is memorized in a predetermined shape in which the wall portion 5 is integrally raised continuously on both sides of the bottom portion 4 to form a reinforcing material 2b, and the reinforcing material 2b is After that, the synthetic resin 3 is injected from the injection port 8 to form the cup-shaped stabilizer 1 in which the reinforcing material 2b and the synthetic resin 3 are integrally formed.

Next, a mesh plate made of an arbitrary shape memory alloy is cut into a predetermined shape and placed in a molding die, and a desired shape is formed by injection pressure and injection heat of a synthetic resin injected into the molding die. An embodiment of a cup-shaped stabilizer having a shape memory stored therein will be described. It forms a continuous form any shape memory alloy mesh plate 2 integrally the wall portion 5 on both sides of the bottom portion 4
The reinforcing material 2c cut into a shape that can be formed 2a is placed in the mold 7, the synthetic resin 3 is injected from the injection port 8, and the injection pressure and heat of the synthetic resin 3 injected into the die 7 are used. Bottom part 4
The cup-shaped stabilizer 1 formed integrally with the synthetic resin so as to form the rising portion 6 integrally and continuously with the wall portion 5 on both sides of is formed.

[0008] The reinforcing material formed of a non-woven fabric made of an arbitrary shape memory alloy is also formed by the same means as described above, but the description of the embodiments is omitted.

As the arbitrary shape memory alloy used in the present invention, there is a Ti-Ni alloy or the like, and as the synthetic resin, a nylon resin, a polyurethane resin or the like having excellent elasticity is preferable. The shape memory temperature of the arbitrary shape memory alloy is required to be higher than the melting temperature of the synthetic resin when the shape is stored in advance, and the shape memory of the reinforcing material of the arbitrary shape memory alloy is simultaneously performed at the time of molding the synthetic resin. In the case of a synthetic resin, one capable of storing a shape within the melting temperature of the synthetic resin is required. The Ti-Ni alloy has a wide degree of freedom in designing the transformation start temperature corresponding to the general melting temperature of the synthetic resin, is easily processed into a thin wire, and is suitable as the shape memory alloy of the present invention.

As for the shape of the cup-shaped stabilizer, as shown in FIG. 1, the bottom surface 4 is formed continuously from the heel to the shoe tip, and the wall surfaces 5 are formed on both sides of the bottom surface 4.
Body or cup-like stabilizer 1 formed continuously shape, it is formed in a shape bottom portion 4 corresponds only to the heel portion as shown in FIG. 2, the wall portion 5 on both sides of the bottom portion 4 continuously form together
It can be arbitrarily formed as required, such as by forming the formed cup-shaped stabilizer 1a. Also, the reinforcing materials 2b, 2c
Can be arbitrarily formed as required, for example, by partially overlapping a plurality of sheets to increase the thickness. Also, when fabricating a mesh material, a thin wire of a shape memory alloy and a thin wire of a synthetic resin such as a nylon resin are combined and woven. Thus, the workability is improved because the bonding of the fine wires of the shape memory alloy can be improved to prevent the deformation of the reinforcing material having the shape memory.

When a non-woven fabric plate using a thin wire of a shape memory alloy is used, a prepreg made of a non-woven fabric plate and a synthetic resin improves workability.

[0012]

[Effect of the Invention] The shape memory alloy used in the present invention has an extremely high elasticity as generally called a superelastic material, and the shape memory alloy can be deformed by an external force. Since it has the property of quickly restoring to its original shape, it is excellent in shape retention without deforming even if it is formed thinner than conventional carbon fiber or glass fiber reinforced materials, and the heel of the human body Accordingly, the adhesiveness is improved, and the stress applied to the heel of the leg during exercise is absorbed by the entire surface of the cup-shaped stabilizer, so that the shock absorption is improved and the foot is prevented from being damaged. In addition, since the counter of the instep is not required in manufacturing, it is economical and the manufacturing method can be simplified. In addition, the elasticity and rigidity of the cup-shaped stabilizer can be adjusted by changing the wire diameter of the shape memory alloy wire and the density of the mesh, so that the degree of freedom of design can be improved and the thickness can be reduced. There is no danger of being damaged.
In addition, it is possible to provide an elegant material in design by making the color tone of the reinforcing material of the arbitrary shape memory alloy and the synthetic resin different colors or making the synthetic resin a transparent material.
