Abstract

PROBLEM TO BE SOLVED: To safely and effectively strengthen a femoral adductor group and an gluteal muscle group via the twisting motion of the whole of legs by applying the constitution that chains locked with each of a pair of turntables pivotally fixed to a base body is hooked to one end of a coil spring via a pulley, and the other end of the coil spring is hooked to the base body. SOLUTION: A pair of turntables 2 and 2 pivotally fixed to a base body 1 are kept tensioned via a chain 5 and a coil spring 7, and prevented against reverse rotation via the stopper part of a chain bracket 4 and a cross member 13. When a pulley support 8 with the chain 5 engaged is moved by turning a load adjustment rod 9, therefore, the coil spring 7 expands and the rotation load of the turntables 2 and 2 can be adjusted. A user stands on each of the turntables 2 and 2 via his/her right left feet separately placed thereon, and concurrently or separately performs a repeated twisting exercise by use of the right and left feet to repeatedly rotate the turntables 2 and 2. For the change of a direction for the twisting exercise, the user reverses his/her body relative to the exercise appliance back and forth.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an exercise device for strengthening the adductor group of the thigh and the group of the gluteal muscles by twisting the entire leg.

[0002]

2. Description of the Related Art Conventionally, exercise equipment for performing torsion movements of legs include Japanese Utility Model Publication No. 58-152959 and Japanese Utility Model Publication No. 58-304.
25 and the like are known.

[0003]

Both of the exercise devices shown in the prior art are mainly exercise devices for stretching the legs, and strengthen the thigh adductor group and the gluteal muscle group by torsion of the entire leg. There is no sports equipment for that purpose.

An object of the present invention is to provide a safe and effective exercise tool that strengthens the torsional force of the legs, that is, the group of adductor thighs and the group of gluteal muscles by the torsional movement of the entire leg.

[0005]

In order to achieve the above object, a torsion exerciser for a leg according to the present invention is provided. Exercise, the torsional force of the leg directly, that is, the adductor thigh muscles,
It strengthens the gluteal muscles.

[0006]

The operation of the exercise equipment of the present invention will be described with reference to the drawings of the embodiment. A pair of turntables 2 attached to the base 1
Is pulled by the chain 5 and the coil spring 7, and the stopper portion of the chain bracket 4 and the cross member 13
When the pulley support 8 on which the chain 5 is hung is moved by rotating the load adjusting rod 9, the coil spring 7 is extended, and the rotational load of the turntable 2 is adjusted.

[0007] The user stands on each of the pair of turntables 2 with separate left and right feet, and performs the torsional repetitive motion simultaneously or separately with the left and right legs to rotate and repeat the turntable 2.
Also, when changing the direction of the torsional movement, the body direction is reversed with respect to the exercise equipment.

[0008]

An embodiment will be described with reference to the drawings. 1 and 2, a base 1 is formed by bending a rectangular steel pipe and welding a cross member 16 obtained by cutting flat steel to two upper portions. The cross member 13 has a hole at the center for passing the rotary shaft bolt 12.

The turntable 2 cuts a wooden board into a circular shape,
It is fixed to the rotation receiving plate 3 by bolts. The rotation receiving plate 3 is formed by cutting flat steel, welding and fixing a chain bracket 4 also serving as a stopper, and forming a hole for passing a rotation shaft bolt 12 in the center. Then, it is axially mounted on the cross member 13 by a rotating shaft bolt 12 and a nut via a bearing.

The chain 5 engaged with the chain 6 bracket 4 with a split pin is hooked to one end of a coil spring 7 via a pulley 6. The other end of this coil spring is
Is mounted on the coil spring bracket 10 welded to the coil spring.

A pulley support 8 that supports the pulley 6 at both ends has a nut portion at the center. A load adjusting rod 9 that is supported by a hole formed in the base 1 is screwed into the nut portion. I have. The load adjusting rod 9 has a knob 11 fixed to an end thereof with a bolt.

[0012]

As described above, the torsion exerciser for a leg according to the present invention works at the time of changing the direction of a human body and exerts the muscle strength of the adductor muscles of the thighs and the gluteal muscles on the legs, knees and hip joints. It is effective because the ligament is strengthened directly by torsion of the leg.
