Description

Hand movement device

The present invention is related to exercise devices, in particular to a hand exercise device.

As modern people use electronic products (such as computers, mobile phones or handheld game consoles, etc.) for longer and longer hours or occupational injuries at work, they often cause swelling, muscle fatigue, soreness, etc., caused by overuse of the wrist. Provide a variety of exercise or rehabilitation equipment for hand stretching exercises.

However, the conventional hand sports equipment is too bulky to be portable and used, and its use mode is single, unable to provide diversified operation modes, and the stretching effect is limited. In addition, the conventional hand sports equipment has a complicated structure, a high manufacturing cost and is not conducive to production, and has shortcomings that need to be improved urgently.

Therefore, it is necessary to provide a novel and progressive hand exercise device to solve the above-mentioned problems.

The main purpose of the present invention is to provide a hand exercise device that can be held for hand stretching exercises.

In order to achieve the above object, the present invention provides a hand movement device, which includes two housings that are relatively rotatably connected with an axis. Each housing includes a side wall and a peripheral wall that turns from the side wall and extends around the axis. The peripheral wall of the two shells can be held by hand.

The hand movement device 1 further includes a belt body 40 which is connected to a housing 10a, 10b to define a hand piercing space, so as to prevent it from falling off. The belt body 40 is made at least partly of an elastic material, such as elastic band, silicon rubber, rubber, flexible plastic, rope or cloth, etc., which has better tightening effect and comfort, and is suitable for most users. Viewed along the axis A, the belt body 40 can overlap the massage part 112. When the palm of the user corresponds to the massage part 112, the hand can be put on the belt body 40, which can achieve the massage effect and is easy to operate. It is not easy to fall off. With reference to FIGS. 5-7, both hands can be held on opposite sides of the hand motion device 1 during operation, and the two housings can be lifted and rotated relative to each other before the hands are not separated from the hand motion device 1 10a, 10b cross the arms to achieve the purpose of stretching the wrists. Of course, it can also meet the needs. Operate and use in different ways. Preferably, the two ends of the belt body 40 are respectively rotatably and detachably connected to the peripheral walls 12a, 12b of the casing 10a, 10b, and the belt body 40 can swing on the opposite two of the hand movement device 1. Side, in order to use the plural rollers 18 for massage. With reference to FIG. 8, in another preferred embodiment of the present invention, the two ends of the belt body 40 are respectively connected to the peripheral walls 12a, 12b of the two shells 10a, 10b, so as to rotate the two shells relative to each other. At 10a and 10b, it is necessary to overcome the restraint of the belt body 40, which can generate torque and provide different training effects. The peripheral walls 12a, 12b of the two housings 10a, 10b are provided with a plurality of connecting recesses 121, and the two ends of the belt body 40 can be selectively connected to the peripheral walls 12a, 12b of the same housing 10a, 10b or respectively connected to the peripheral walls 12a, 12b of the same housing 10a, 10b. Second, the peripheral walls 12a, 12b can be disassembled and adjusted according to usage requirements.
