Description

Hand training device and its housing

The present invention relates to a training device and its shell, in particular to a hand training device with multiple grips and its shell.

The wrist training ball system uses the gyroscope principle, and the wrist training ball can be started to rotate only mechanically, so the user can hold and rotate the wrist training ball with the palm of the hand, so that it can produce a strong rotation under the action of centrifugal force and inertial force strength. Therefore, the muscles of the hands and shoulders can be exercised by using this rotational force.

However, because the traditional wrist training ball is designed to be operated with one hand, the user can only operate the wrist training ball individually with the left or right hand, and cannot operate the wrist training ball with both hands simultaneously to achieve the benefits of simultaneous training of both hands. In addition, although the traditional wrist strength training ball can train the user's hands and shoulders, the training effect is more focused on the user's wrist. Therefore, how to improve the traditional wrist strength training ball to achieve the benefits of simultaneous training of both hands and multi-part training is one of the problems that the research and development personnel should start to solve.

The present invention is to provide a hand training device and its shell, so that the hand training device can achieve the benefits of simultaneous training of both hands and multi-position training through the arrangement of multiple grip parts.

A hand training device disclosed in an embodiment of the present invention includes a shell, a ring and a rotating body. The shell includes two casings and a circular track. The two housings are detachably mounted to each other to jointly enclose an accommodating space, and the circular track is fixed in the accommodating space. The circular track has a circular groove. The collar is rotatably arranged in the annular groove. The collar includes a ring body and an assembly. The opposite sides of the ring body respectively have a first combination part and a first shaft hole part. The different parts of the assembly parts respectively have a second assembly part and a second shaft hole part. The second combination part of the assembly is installed on the first combination part of the ring body. The body of revolution contains two relative protruding axes. The two protruding shafts are respectively rotatably located in the first shaft hole and the second shaft hole of the collar, so that the rotating body can rotate relative to the collar. Wherein, each of the two casings includes a first protruding portion, a second protruding portion and a third protruding portion connected to each other. The first protrusion is located between the second protrusion and the third protrusion, so that a depression is formed between the first protrusion and the second protrusion and between the first protrusion and the third protrusion. The two first protrusions together form an assembly part. The circular track is installed in the assembly part. The two second protrusions jointly form a first gripping portion. The two third protrusions jointly form a second gripping portion.

The shell of the hand training device disclosed in another embodiment of the present invention is used for setting a rotating body. The shell of the hand training device includes two casings and an annular track. The two housings are detachably installed with each other to jointly surround an accommodating space. The circular track is fixed in the accommodation space. Wherein, each of the two casings includes a first protruding portion, a second protruding portion and a third protruding portion connected to each other. The first protrusion is located between the second protrusion and the third protrusion, so that a depression is formed between the first protrusion and the second protrusion and between the first protrusion and the third protrusion. The two first protrusions together form an assembly part. The circular track is installed in the assembly part. The two second protrusions jointly form a first gripping portion. The two third protrusions jointly form a second gripping portion.

According to the hand training device of the above-mentioned embodiment, by forming two protruding first gripping parts and second gripping parts on the casing, the user can exercise both hands at the same time. In addition, since both hands are trained at the same time, the hand training device can provide exercise modes different from traditional ones. In this way, in addition to training the user's wrist, the hand training device can train the user's shoulders, upper arms, and forearms more emphatically. That is to say, the training part of the hand training device is no longer limited to the wrist of traditional wrist ball training, but can achieve the benefits of multi-part training.
