Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a muscle strength training device for strengthening the muscle strength of the thigh muscles, brachial muscles and the like.

[0002]

[Prior Art]

 Conventionally, when strengthening the muscle strength of the thigh muscles and brachial muscles, etc., one has to go to a health club or the like and perform muscle strength training using a large training machine, or purchase an expensive training device for training. It was

[0003]

[Problems to be solved by the device]

 However, there is a problem that it is troublesome to go to a health club in the conventional strength training and that it is expensive to purchase at home.

The present invention is intended to provide a strength training device which aims to solve the above conventional problems.

[0005]

[Means for Solving the Problems]

 According to the present invention, the upper and lower ends of the coil spring are linearly extended in the left-right direction, respectively, and the upper and lower linear parts are connected to the upper and lower linear parts. The upper and lower curved portions that are bent toward the coil spring side, and the upper and lower tip portions that are connected to the upper and lower curved portions and are bent in the direction of the upper and lower linear portions are integrally connected. The coil springs are covered with caps from above and below, and the upper and lower straight portions, the upper and lower curved portions, and the upper and lower tip portions are covered with a cushion material having an annular cross section. The above problems have been solved by adopting a means of providing symmetrical operation parts on the upper and lower parts.

[0006]

[Action]

 According to the present invention having the above-mentioned configuration, it is possible to strengthen the muscular strength by training safely and easily using the elastic force of the coil spring.

[0007]

【Example】

 An example of an embodiment of the present invention will be described in detail with reference to the drawings. The upper and lower ends of the coil spring 1 are linearly extended in the left-right direction, respectively, and are expanded into an approximately L-shape. , 3 are connected in series, and are further connected to the upper and lower linear portions 2 and 3 to be bent toward the coil spring 1 side, and upper and lower curved portions 4 and 5, and the upper and lower curved portions 4, 5 The upper and lower straight portions 2, 7 are bent in the directions of the upper and lower portions, and the upper and lower tip portions 6, 7 are integrally connected to each other, and the coil spring 1 is covered with the caps 8, 9 from above and below. At the same time, the upper and lower linear portions 2 and 3 which are close to the coil spring 1 are also covered with the tubular coating pipes 10 and 11 which are integrally projected on the caps 8 and 9, and the upper and lower linear portions 2 are further covered. , 3, the upper and lower curved portions 4 and 5 and the upper and lower tip portions 6 and 7 have a cross-section ring of a relatively thick sponge or the like. The was coated with a cushion material 12, on the respective coil spring 1 is formed by projecting the operating portion 13, 14 of the left and right symmetrical at the bottom.

[0008]

Next, the operation of the embodiment will be described. The training device of the present invention, for example, as shown in FIG. 3, after sitting on a chair or the like, the coil spring 1 is placed downward, and the thigh muscles of both legs are sandwiched between the operation parts 13 and 14, so that the elastic force of the coil spring 1 is exerted. Against this, a motion of closing both operating feet 13 and 14 by narrowing them and then relaxing the operating force of both feet and expanding both operating operations 13 and 14 by the elastic force of the coil spring 1. The thigh muscles can be trained by repeating.

Further, as shown in FIG. 4, one operation portion 13 is pressed against the upper arm, the bending portion 5 of the other operation portion 14 is grasped, and force is applied to the arm to move the operation portion 14 to the coil spring 1. The elastic force of the coil spring 1 is returned to the original position by moving the arm to the one operation part 13 side, and then releasing the force of the arm. The brachial muscles can be trained by repeating the chewing movement.

Even when the body is trained using the training device of the present invention, the coil spring 1, the upper and lower linear portions 2 and 3, the upper and lower curved portions 4 and 5, and the upper and lower tip portions 6 and 7 are Since all are covered with the caps 8 and 9, the coated pipes 10 and 11, and the cushion material 12, the metal portion is not exposed to the outside and can be used safely.

[0011]

[Effect of the device]

 Since the present invention is as described above, it is lightweight, easy to operate, does not need to go to a health club, etc., and it is possible to safely train body muscle strength at home, and the structure is simple and inexpensive to manufacture. There are great things to do, such as being able to do so.
