JPH11333024A - Training device for strengthening gripping and wrist power by applying load to joint of finger or wrist to pull it to the side of back of hand when hand is held or wrist is bent inward - Google Patents

Abstract

PROBLEM TO BE SOLVED: To strengthen a hand gripping power and a wrist power by applying a load when fingers or wrist are bent inward. SOLUTION: A repelling force of an extendable and shrinkable member made of rubber or spring and fixed to the side of back of finger joints and a wrist is applied when the finges and wrist are bent. Accordingly, this device is effective to not only athletes and persons engaged with jobs requiring a physical strength but also aged persons hard to perform a strong exercise for improving the underexercised conditions and improving the health.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elastic device, such as rubber or a spring, which is stretched when a force is applied to the back of a hand and fixed at a fixed position. It is a device that applies a load to the muscles of the wrist by bending inward, and strengthens the grip strength and wrist strength.

[0002]

2. Description of the Related Art Conventional grip strength training devices are of a type that is held and held by a hand, and is intended to strengthen the grip strength of the entire palm. It was troublesome to use it regularly. In order to strengthen the power of the wrist, heavy iron dumbbells are used or they are performed as part of the whole body exercise, so there were restrictions on place and time.

[0003]

SUMMARY OF THE INVENTION The present invention is easy to carry and can change the applied force depending on the user and the purpose of use, and can be used in various ways from strengthening the grip of athletes to maintaining the health of the elderly. It was invented as a device that can do it.

[0004]

Means for Solving the Problems The present invention is characterized in that: (a) a part which supports a tall telescopic device at the back side of a position where a joint other than a finger joint and a wrist is sandwiched is fixed, and both ends of the telescopic device are fixed; Is fixed. (B) The wrist side should be glove-like without fingers, and one of the ends should be fixed there.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION In the embodiment of the present invention, first, the device is mounted on a hand and fixed firmly with a velcro or the like. Then, when the hand is gripped, an elastic device such as a rubber or a spring having both ends fixed along the finger rebounds while extending. For this reason, in order to grip the hand, a force exceeding the repulsive force of the expansion / contraction tool is required, and a load is applied to the fingers and hand muscles. Since the strength of the finger joints varies greatly depending on the location, changing the strength of the expansion and contraction equipment for each joint allows for easy training. In addition, if the expansion and contraction device has a replaceable structure, it can be changed in accordance with the strengthening of the muscular strength, which is efficient. The same principle applies to the wrist, and when the wrist is bent inward, a load is applied by the repulsive force of the elastic device fixed at a position sandwiching the joint of the wrist, and the muscle strength is trained.

[0006]

The strength of the grip and the power of the wrist are the basis of many exercises, and training of the grip strength is also effective for maintaining health and preventing aging. If the present invention makes it easy to train the grip and wrists reasonably for the individual and the purpose, it will not only help athletes and those who work in occupations requiring physical strength, but also exercise daily. It is also very effective in relieving shortages and maintaining the health of elderly people who cannot exercise.

Claims (3)

[Claims] 1. A device for fixing and attaching to the back side of the hand an object that expands and contracts when a force such as rubber or a spring is applied, and applies a pulling load to the finger muscles when gripping the finger, thereby strengthening the grip force. 2. A wrist joint that is stretched when a force such as rubber or a spring is applied is fixedly attached to a joint portion of the wrist, and a tension load is applied to a muscle of the wrist when the wrist is bent inward. A device that trains power. 3. The mechanism according to claim 1, wherein the extension device is divided for each finger joint and can be easily replaced, and the load for each joint can be changed depending on a user or a purpose of use.
