Description

  The present invention relates to a strength training device that involves dynamic contraction of muscles, and particularly to a strength training device that is lightweight enough to be carried and has excellent storability when not in use.

  Conventionally, a stationary training machine is generally used as a strength training tool. For example, Patent Document 1 discloses a training machine having a relatively simple structure. Moreover, as a simple training tool that can be carried, an elastic body is sandwiched between upper and lower limbs (for example, Patent Document 2), or an upper and lower limb is restrained by a rigid body and the rigid body is pressed inward and outward (for example, Patent Document) 3) has been proposed. Tubes and dumbbells are also used.

  However, since the training machine of Patent Document 1 applies a load by utilizing the weight of the user, there is a problem that the magnitude of the load is different when the lower limb is opened and closed, and the knee and hip joint are also burdened. Was. When a fluid cylinder or the like is used to adjust the load, the training machine becomes heavy and difficult to carry.

  The training device of Patent Document 2 uses an elastic body sandwiched between lower limbs. The load continuously changes depending on the amount of compression of the elastic body, and the load is applied only in the direction of closing the lower limbs. Had the task of being trained but not abductor muscles. In addition, since the training device of Patent Document 3 fixes the lower limbs with a rigid body, both the adductor muscle group and the abductor muscle group can be loaded, but training (isometric exercise) that does not involve dynamic stretching of the muscle, It was difficult to obtain the training effect of muscular strength that was exhibited during movement.

  Similar to the training tool of Patent Document 2, the tube continuously changes the load depending on the amount of elongation of the tube, and the load is applied only in the direction of extending the tube. Furthermore, the size of the load changes depending on the joint angle of the dumbbell. For this reason, the conventional lightweight training device is applied during one cycle of dynamic muscle contraction (for example, in the case of hip joint opening and closing, the process from opening the lower limb to closing the lower limb and closing it again to the initial position). There was a problem that the load variation was large and the strength training efficiency was low.

  An object of the present invention is to solve such a problem and to provide a strength training device with dynamic contraction of a muscle that is lightweight and easy to carry.

  The strength training device of the present invention is formed in a planar shape, each of two independent base materials, a base material formed in a planar shape and connected to the ends of the two base materials within one surface, and a surface Two end portions facing each other and two positions spaced from the end portions are connected to each other on the surfaces of the two base members, and the two base members each have Two or more independent deformable hermetic containers are mounted in the base material, and the hermetic containers mounted on the same base material are connected by a path for fluid movement, and at least one of the hermetic containers is 1 The muscle strength training tool is characterized in that the fluid inlet 13 is provided.

  Preferably, the two base members of the strength training device of the present invention are strength training devices that are specularly shaped so that the change in load during one cycle of dynamic muscle contraction is reduced.

  More preferably, at least one of the sealed containers is provided at a position corresponding to an outer surface of an upper limb or a lower limb of the wearer of the strength training device, and at least another one corresponds to an inner surface of the upper limb or the lower limb of the wearer. It is a strength training device characterized by being provided at a position.

  ADVANTAGE OF THE INVENTION According to this invention, the load change in 1 cycle of the dynamic contraction of a muscle is small, and when not in use, it can be folded and can provide a strength training tool that can be easily stored and transported.

It is a strength training device of the present invention. It is a schematic diagram at the time of use of the strength training tool of the present invention. A base material for strength training equipment. It is a base material of a strength training device. It is use explanatory drawing of the strength training tool of this invention. It is a conventional stationary training machine. It is a conventional simple training tool.

  An embodiment of the strength training device of the present invention will be described with reference to FIG. The strength training device 1 of the present invention is formed in a planar shape, each of two independent base materials 2a and 2b, and is formed in a planar shape, and the end portions 100 of the two base materials 2a and 2b are formed in one surface. The two base parts 2a and 2b formed on the two base members 2a and 2b, respectively. The two base members 2a and 2b are provided with two or more independent deformable sealed containers 5 attached to the two base members 2a and 2b, and are attached to the same base member. In addition, the sealed container 5 is a strength training device that is connected by a path 12 for fluid movement, and at least one of the sealed containers 5 is provided with one or more fluid inlets 13. .

  FIG. 2 is an assembly view of the strength training device 1 of the present invention. The connecting means 11a, 11b arranged near the ends 100b of the two base members 2a, 2b and the connecting means 10a, 10b arranged near both ends of the base material are connected to each other, and the two annular parts 110, 111 are connected. Form. At this time, the sealed container 5 is disposed on the surfaces 114 and 115 facing the distal surfaces 112 and 113 where the two annular portions are close to each other.

  Here, a thigh training tool will be described as an example. The two annular portions 110 and 111 are formed by winding the base material and the base material around the lower limb and connecting the connecting means 10a and 10b and the connecting means 11a and 11b. At this time, the sealed containers disposed on the surfaces 112 and 113 are placed on the inner surface of the wearer's upper limb or lower limb, and the sealed containers provided on the surfaces 114 and 115 are placed on the outer surface of the wearer's upper limb or lower limb. . Here, the outer surface of the upper or lower limb is the surface in the direction of abduction or rotation of the joint of the upper limb or lower limb, and the inner surface of the upper or lower limb is the surface of the direction of inversion or rotation of the joint of the upper limb or lower limb. Say.

  Further, if the two base materials 2 to which the two or more deformable sealed containers 5 are attached are mirror-targeted shapes, the load on the upper limb and the lower limb can be equalized on the left and right, and muscle strength training can be performed in a balanced manner. it can. In addition, the mirror surface object here means that the shape of two base materials is the same, and the front and back are reversed.

  FIG. 3 is a component diagram of the base material 2. The base material 2 is composed of a surface material and a lining material, and is formed by fixing the periphery with a reinforcing tape. In the vicinity of the end portion 100b, a connecting means 11 (in this embodiment, a hook-and-loop fastener) that is detachably connected to the base connecting means 10 is fixed. Further, in the vicinity of the end portions 100 and 100b, a deformable sealed container 5 is disposed between the outer material and the lining material. The airtight container 5 is attached by fixing the outer surface and the lining around the airtight container. Further, a hole 51 through which the path 12 connecting the sealed container 5 is passed is provided in the outer surface, and a hole 52 corresponding to the injection hole is further provided. As a fixing method, sewing or adhesion is used.

  This base material is used for a thigh strength training tool, and has a total length L of 590 mm and a total width B of 250 mm. In order to obtain a good wearing feeling (adhesion feeling), the outer shape of the base material is a fan-shaped outer shape according to the outer circumference of the thigh, but a simple rectangle or the like can be adopted according to the site to be used.

  FIG. 4 is a component diagram of the base material 3. The base material 3 is made of a cloth and is formed by fixing the periphery with a reinforcing tape. In the vicinity of both ends of one surface of the base material 3, connection means 10 that can be detachably connected to the connection means 11 of the base material 2 is disposed. Further, the end portions 100 of the two base members 2 are connected at positions separated from the end portions (the broken line 55 is an imaginary line at a position where the end portions 100 are connected). The base material 3 is provided in a fan shape so as to match the opening and closing movements of the upper limbs and the lower limbs, and the two base materials are connected so as to open to one side so as to enhance the wearing feeling.

  An example of using the thigh strength training device 1 of the present invention will be described with reference to FIG. Here, the near side is the base side of the lower limb, and the arrow D is the direction in which the joint of the lower limb is abducted or rotated. The connecting members 10 and 11 are connected to form the annular portions 110 and 111 so that the base material 2 and the base material 3 are wound around the thighs of both lower limbs. The annular portion 110 corresponds to the right foot, and 111 corresponds to the left foot. The airtight containers 5 arranged on the surfaces 112 and 114 and the surfaces 113 and 115 are connected to each other by a path 12, and fluid is injected into the airtight container 5 from the inlet 13 in advance.

  In this use example, the surfaces 114 and 115 correspond to the outer surfaces of the lower limbs, the surfaces 112 and 113 correspond to the inner surfaces of the lower limbs, and the sealed containers 5 disposed on the surfaces 112 and 114 and the surfaces 113 and 115 are respectively routed. 12, and when the joint of the lower limb is moved in the direction of abduction or rotation, the sealed container of the inner surface is moved from the sealed container of the outer surface to the sealed container of the inner surface, and when the joint of the lower limb is moved in the direction of adduction or rotation. The fluid moves from the path to the outer sealed container. Although the load during fluid movement varies slightly depending on the opening / closing speed of the thigh, the training effect of the adductor muscle group and the abductor muscle group is high because most of the exercise is a constant load. Although the path 12 is provided at an arbitrary position, it is desirable that the path 12 is disposed outside the annular portion so as to protect the path 12 and change the wearing feeling, and pass between the base member 2 and the connecting member 4.

  In this example, nylon or polyester is used for the base material, the base material, and the connecting material, but rayon, cotton, polyurethane and the like can also be used. Polyurethane is used for the sealed container, but polychlorinated biphenyl or olefin EVA can also be used. Moreover, although air was used as the fluid, it is possible to use gas, liquid, or solid fluid according to the required load. Further, the load may be adjusted by providing a flow rate adjusting means in the path.

  In addition, although the training device for the thigh was described in this embodiment, it is widely used for other strength training devices such as flexion and extension of the thigh, internal and external rotation of the hip joint, upper limb (upper arm), shoulder, chest, and calf. Is possible.
