Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention mainly relates to improvement of a core material of a sports supporter for protecting bending and stretching parts such as elbows and knees.

[0002]

[Prior art]

As shown in FIG. 4 showing an embodiment of the present invention, a sports supporter used for protection of elbows, knees and the like has two flattened flat surfaces facing each other in the length direction of the supporter. There is a type in which a bag is sewn and a core material is inserted into the bag. Conventionally, as shown in FIG. 6, a core member of this type has one of two left and right coil springs A ₁ and A ₂ each having a constant length and made of a single metal wire. Another coil spring A ₂ sandwiched between each pitch of the coil spring A ₁ is pressed to a predetermined thickness to form a flat long piece A, and both ends of the elongated piece A are substantially U-shaped locking tools B. , B are fitted and crimped.

[0003]

[Problems to be solved by the device]

The core material to be inserted into the bag provided in the supporter is flattened by entwining left-handed and right-handed coil springs A ₁ and A ₂ made of a single metal wire as described above. Since the strength of the core material is low when using, the supporter with this core material is worn on flexion and extension parts such as elbows and knees, and when performing flexion and extension movements, the supporter wear position at the flexion and extension parts shifts and The material may break. An object of the present invention is to provide a core material for a supporter, which can maintain the wearing position of the supporter even during flexion and extension movements in sports and which does not break.

[0004]

[Means for Solving the Problems]

 The core material 1 for the supporter is formed by forming a left-handed coil spring 1a and a right-handed coil spring 1b having a predetermined length from a metal wire material. Each of the left and right coil springs 1a and 1b shall be made by winding multiple wire rods on top of each other, and by winding multiple wire rods on each coil pitch 1a. Then, the other coil spring 1b is pressed into a flat thickness so as to have a flat shape.

[0005]

[Action]

 For example, as shown in FIG. 5, the supporter worn on the flexion / extension part of the elbow will be described as an example. The main core 1 is inserted into the flat bag body 3 formed in the longitudinal direction of the supporter 2. Since the left and right coil springs 1a and 1b are each wound by laminating a plurality of wire rods, the mechanical strength of the core material as a whole is significantly increased, and the supporter having the main core material 1 is used for elbows and knees. The core material 1 does not break when worn on the flexion / extension part and bends / expands, and an ellipse formed by entwining and pressing the coil springs 1a and 1b in which a plurality of wire rods are wound and wound. Due to the orderly and close stacking of the rings 4 and 4 of shapes and the like, the core material 1 is bent by an appropriate degree of elasticity that does not impair the support function as a supporter that protects the bending and stretching portions.

【Example】

 An embodiment of a core material for a supporter of the present invention will be described with reference to the accompanying drawings. 1 to 3 show an embodiment of the present invention, FIG. 4 shows a state in which the core material shown in the embodiment is attached to a supporter, and FIG. 5 shows a state in which the supporter shown in FIG. 4 is worn on an elbow. In the embodiment shown in FIG. 1, one of the left-handed coil springs 1a and the right-handed coil springs 1b, which is formed by winding a metal wire in a double shape and winding it in a circular shape, is provided between the coil springs and the other coil springs. The coil spring is flattened by pressing it to a certain thickness while sandwiching it. FIG. 2 shows only the coil spring 1a in which a plurality of wire rods are stacked and wound in a left-hand winding, and FIG. 3 shows only the coil spring 1b in which a plurality of wire rods are stacked and wound in a right-hand winding.

As shown in FIGS. 4 and 5, for example, the main core 1 is inserted into a flat bag body 3 provided so as to face each other in the longitudinal direction of the supporter 2 to be worn on the flexion / extension part of the elbow. . Since the left and right coil springs 1a and 1b that are entwined with each other are doubled, the mechanical strength of the entire core material is significantly increased compared to the conventional one. In addition to that, as shown in FIG. 1, the elliptical rings 4 and 4 formed by pressing the left and right double-wound coils 1a and 1b intertwined with each other are neatly and closely stacked. Therefore, when the supporter 2 having the main core material 1 is worn and stretched on the bending and stretching parts such as the elbow and the knee, the wearing position of the supporter 2 does not move, and the bending and stretching parts are stably protected. The core material 1 will not be broken while it will be bent by an appropriate degree of elasticity that does not impair the support function as a supporter.

The wire used in the core material of the present invention may be a spring steel wire, a hard steel wire, a stainless steel wire for springs, a piano wire, a carbon steel oil temper wire for springs, and the like. It is recommended to determine the wire diameter, coil spring winding diameter, pitch, etc. in consideration of the properties, but the left and right winding coils each have multiple wires wound around each other and the strength is sufficiently maintained. It is not necessary to use a high quality wire rod having a large size. The left and right winding coils before being entangled and pressed is not limited to a circular shape as in the embodiment, and may be wound in a shape other than a circular shape such as a rectangular shape, and the wire may be formed in a shape other than a double shape such as a triple shape. Of course, a plurality of layers may be wound and wound.

As described above, the core material of the present invention is not only one in which the mechanical strength is increased as compared with the conventional one in which single wire rods are entangled and pressed, but also retains high strength. However, it flexes with an appropriate degree of elasticity that does not impair the support function as a supporter that protects the bent and stretched parts.

[0010]

[Effect of device]

 According to the present invention, the core material is formed by entwining and pressing both left-handed and right-handed coil springs in which a plurality of wire materials are wound in layers, so that the core material does not break and the sports supporter does not break. It is possible to maintain sufficient mechanical strength as a core material, and it is economical because it is not necessary to use a high-grade wire material having high strength. In addition to its high strength, the ring formed by entwining and pressing the left and right coil coils, which are formed by winding multiple wire rods in an intertwined manner, orderly and densely overlap each other. When flexing and stretching exercises while wearing the elbows and knees on the flexion / extension part, the supporter's wearing position does not shift, and the supporter functions as a supporter so that it flexes with an appropriate degree of elasticity to stabilize the flexion / extension part. Can be protected.
