Description

[Technical Field]

[0001] The present invention relates to a stretch cord and composite spring structure that can be used not only for post-sports maintenance and medical rehabilitation but also for acupressure and pressure in general daily use, with the aim of improving and preventing physical pain, twisting, and joint deformation caused by weakened muscles and muscle fatigue. [Background technology]

[0002] Most muscles that move the body are attached to bones via tendons, and move by rotating joints, so pain and stiffness in the body occur along the nerves and tendons. Also, because the body is a collection of levers, it rotates many joints at once and moves using many muscles around bones as axes. Therefore, to resolve pain and stiffness, it is necessary to relieve tension in the many muscles and tendons involved in the pain and stiffness, but because pain occurs when muscles and tendons tense up and contract, putting pressure on nerves, it is also necessary to prevent the muscles and tendons from contracting.

[0003] Therefore, a supporter that can apply pressure, acupressure, and stretching has been proposed. In this supporter, a spring steel wire is covered with a tube member, which is further covered with an elastic material, and a hook-and-loop fastener or the like is attached to the main body of the supporter, which can be worn by wrapping it around the body to apply pressure, acupressure, and stretching (see, for example, Patent Documents 1 and 2).

[0023] Fig. 5 is a diagram for explaining the connection structure between the first spring steel wire (1) and the second spring steel wire (1a) in the stretch cord (11) capable of applying pressure, finger pressure, and stretching according to embodiment 1. Fig. 5(a) is a diagram showing the entire first spring steel wire (1) and the second spring steel wire (1a), Fig. 5(b) is a diagram showing the state before the first spring steel wire (1) and the second spring steel wire (1a) are connected, and Fig. 5(c) is a diagram showing the state after the first spring steel wire (1) and the second spring steel wire (1a) have been connected.

[0024] As shown in FIGS. 1 and 2, the stretch cord (11) according to the first embodiment, which is capable of applying pressure, acupressure, and stretching, comprises a first spring steel wire (1) to both ends of which second spring steel wires (1a) thinner than the first spring steel wire (1) are connected, and the first spring steel wire (1) and the second spring steel wire (1a) are passed through a tube member (2), forming a composite spring structure (3). One end of this composite spring structure (3) is connected to a ring member (4), forming a tube main body (5). The stretch cord (11) can be worn by wrapping it around the body to apply pressure, acupressure, and stretching.

[0025] As shown in Figures 6 and 7 described below, when the stretch cord (11) according to the first embodiment, which is capable of applying pressure, acupressure, and stretching, is wound around the body and worn, the elasticity of the first spring steel wire (1) and the second spring steel wire (1a) applies a pressure effect to the muscles and tendons, preventing them from being pushed outward. When the body is moved with the stretch cord (11) wound around the body and worn, the elasticity of the first spring steel wire (1) and the second spring steel wire (1a) stimulates the muscles and tendons with an acupressure effect, relieving stiffness in the muscles and tendons. When the stretch cord (11) is wound around the body in a spiral shape and worn, the force of the first spring steel wire (1) trying to return to its original position applies a stretch effect to the muscles and tendons, preventing them from contracting.

[0026] In the stretch cord (11) according to embodiment 1, which can apply pressure, finger pressure, and stretch, one end of the main tube portion (5) is connected to the ring member (4) by a structure in which the ring member (4) is sandwiched at the folded portion (6) of the tube member (7) containing the second spring steel wire (1a) therein, as shown in FIG. 2(c).

[0027] In the stretch cord (11) according to the first embodiment, which can be applied with pressure, finger pressure, and stretching, the main tube part (5) has a structure in which the composite spring structure (3) is covered with an elastic tube (8), as shown in FIG.

Here, the fastener is, for example, a rubber band.

[0029] In the stretch cord (11) according to embodiment 1 that can be applied with pressure, finger pressure, and stretched, the elastic tube (8) located at the other end of the main tube portion (5) has a knot (10) of a hollow tube that does not contain the second spring steel wire (1a) inside, as shown in FIG. 4(b).

[0030] In the stretch cord 11 according to the first embodiment, which can be pressed, pressed by a finger, and stretched, the second spring steel wire 1a is composed of a second spring steel wire 1a arranged at one end of the tube main body 5 and a second spring steel wire 1a arranged at the other end of the tube main body 5, as shown in Figures 1, 2, and 5. The second spring steel wire 1a arranged at the other end of the tube main body 5 is longer than the second spring steel wire 1a arranged at one end of the tube main body 5.

[0031] The composite spring structure (3) provided in the stretch cord (11) capable of applying pressure, acupressure, and stretching according to embodiment 1, i.e., the composite spring structure (3) having a structure in which a second spring steel wire (1a) thinner than the first spring steel wire (1) is connected to both ends of a first spring steel wire (1), and these first spring steel wire (1) and second spring steel wire (1a) are passed through a tube member (2), has economic value on its own and can also be distributed on its own.

[0032] In the stretch cord (11) according to the first embodiment, which can be applied with pressure, finger pressure, and stretched, the first spring steel wire (1) and the second spring steel wire (1a) are connected by a connecting heat-shrinkable tube (20) or a connecting elastic tube, which is filled with adhesive and covers the first spring steel wire (1) and the second spring steel wire (1a), as shown in Fig. 5. The connecting heat-shrinkable tube (20) or the connecting elastic tube is made of a waterproof material.

[0033] In the stretch cord (11) according to the first embodiment, which can be applied with pressure, finger pressure, and stretched, the first spring steel wire (1) and the second spring steel wire (1a) may be connected by a connecting heat shrinkable tube (20) or a connecting elastic tube that covers them, as shown in FIG. 5.

[0034] In the first embodiment, the first spring steel wire (1) has a diameter of, for example, 0.6 mm and a length of, for example, 1000 mm, the second spring steel wire (1a) has a diameter of, for example, 0.3 mm, the second spring steel wire (1a) arranged at one end has a length of, for example, 500 mm, and the second spring steel wire (1a) arranged at the other end has a length of, for example, 1200 mm. The tube member (2) is made of, for example, a silicone tube with a hardness of 40 degrees, and has an outer diameter of 4 mm, an inner diameter of 2 mm, and a length of, for example, 2620 mm. The tube member (2) is preferably made of a waterproof material. The elastic tube (8) is made of, for example, a polyester cord, and has an inner diameter of, for example, 16.4 mm and a length of, for example, 2900 mm. The ring member (4) is made of, for example, a silicone ring with a hardness of 40 degrees, and the ring has a thickness of, for example, 3 mm, an outer diameter of, for example, 30 mm, and an inner diameter of, for example, 24 mm.

[0035] The stretch cord (11) according to the first embodiment, which can apply pressure, acupressure, and stretching, uses a spring steel wire in which a first spring steel wire (1) has second spring steel wires (1a) thinner than the first spring steel wire (1) connected to both ends thereof. Therefore, according to the first embodiment, it is possible to provide a stretch cord and a composite spring structure for use therewith that are easy to attach and fasten and have a structure that easily fits various joints of different sizes, including those around the fingers and toes.

[0036] Furthermore, according to the first embodiment, when the stretch cord (11) is wound around the body and worn, the elasticity of the first spring steel wire (1) and the second spring steel wire (1a) exerts a pressure effect on the muscles and tendons, preventing them from being pushed outward; when the body is moved with the stretch cord (11) wound around the body and worn, the elasticity of the first spring steel wire (1) and the second spring steel wire (1a) stimulates the muscles and tendons with an acupressure effect, relieving stiffness in the muscles and tendons; and when the stretch cord (11) is wound around the body in a spiral shape and worn, the force of the first spring steel wire (1) trying to return to its original position exerts a stretching effect on the muscles and tendons, preventing them from contracting.

[0037] According to embodiment 1, one end of the tube main body (5) is connected to the ring member (4) by a structure in which the ring member (4) is sandwiched at the folded portion (6) of the tube member (7) that contains the second spring steel wire (1a) thinner than the first spring steel wire, as shown in Figure 2(c), so that the connection work between the tube main body (5) and the ring member (4) can be easily performed.

[0038] According to the first embodiment, the tube main body (5) has a structure in which the composite spring structure (3) is covered with the elastic tube (8), as shown in FIG. 3, and by adjusting the material and hardness of the elastic tube (8), the pressure effect, acupressure effect, and stretching effect can be made appropriate.

[0039] According to the first embodiment, the elastic tube 8 located at one end of the main tube portion 5 has a structure in which it is tightly fastened by winding the fastener 9 around it, as shown in Fig. 4(b), which facilitates the attachment of the elastic tube 8. Furthermore, the main tube portion 5 and the elastic tube 8 can be prevented from shifting longitudinally when attaching the stretch cord 11 or when continuing to use the stretch cord 11.

[0040] According to the first embodiment, the elastic tube (8) located on the other end side of the tube main body (5) has a hollow tube knot (10) that does not contain the second spring steel wire (1a) inside, as shown in FIG. 4(b), and therefore the other end of the stretch cord (11) can be easily processed.

[0041] According to embodiment 1, the second spring steel wire (1a) consists of a second spring steel wire (1a) arranged on one end side of the tube main body (5) and a second spring steel wire (1a) arranged on the other end side of the tube main body (5), thereby realizing a composite spring structure (3) with a simple structure.

[0042] According to the first embodiment, the first spring steel wire (1) and the second spring steel wire (1a) are filled with adhesive inside and connected by a connecting heat shrink tube (20) or a connecting elastic tube that covers the first spring steel wire (1) and the second spring steel wire (1a), so that the above-mentioned composite spring structure can be produced with a simple process.

[0043] In the stretch cord (11) according to the first embodiment, which can be applied with pressure, finger pressure, and stretched, the first spring steel wire (1) and the second spring steel wire (1a) may be connected by a connecting heat-shrinkable tube (20) or a connecting elastic tube that is not filled with adhesive. Even in such a case, the composite spring structure described above can be produced with a simple process.

[0044] [How to use] 6 and 7 are diagrams illustrating an example of use of the stretch cord 11 capable of applying pressure, acupressure, and stretching according to embodiment 1.
