Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gripping device using both hands, which is used for sports, physical strength, and strength enhancement.

[0002]

2. Description of the Related Art Grip force devices are used as sports equipment and exercise devices for improving grip force, but in the conventional structure, grip force devices that utilize repulsive force such as springs and rubber are often used and are held by one hand. It's easy. Therefore, there is a drawback that the grip strength can be strengthened only within the range of the repulsive force of the spring or rubber, and as the grip strength becomes stronger, it is replaced with a stronger gripping device, or the strength of the function is increased by increasing the number of times of use. There were some aspects that were structurally inadequate.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems.
The object is to propose a gripping device that does not require a mechanical gripping force limit with individual gripping devices, and to develop a gripping device with only fingertips while strengthening the gripping power of the entire fingers. Furthermore, the development of an easy-to-use gripping force device that strengthens each other by utilizing the gripping force of both fingers or both fingertips with one device was made a problem to be solved.

[0004]

[Means for Solving the Problems] As means for training the grip strength of both hands to achieve the above object, upper and lower supports obtained by forming a mating surface into a curved arc shape and superposing the same are provided at appropriate intervals.
A grip shaft is rotatably connected between the end portions of the adjacent upper and lower supports, and the upper and lower supports are swingably connected to each other via a link rod pivotally connected to the grip shaft in a cross shape. In item 2, as a means for training the gripping force of only the fingertip, the mating surface is formed by an arc-shaped curved line and is composed of a vertically superposed plate body, and a support shaft is fixed to both ends of the upper and lower plate bodies. As a means, a gripping force device in which the upper and lower plates are swingably connected to each other through a link rod pivotally attached to the support shaft in a cross shape,
According to a third aspect of the present invention, a gripping force device is used in which the upper and lower supports connected to the grip shaft are swingable through a link rod connected to the grip shaft in a cross shape.

[0005]

[Function] If the grip shafts of the upper and lower supports or both ends of the board are held with both palms and the force of the fingers is applied, the action of the link rod pivoted in a cross shape allows the upper and lower supports to be gripped and gripped. Freely swing by the difference of.

EXAMPLE An example of claim 1 will be described with reference to the drawings. FIG. 1 shows a perspective view of a two-handed gripping force device, and FIG. 2 shows a structural action of the link rod of FIG. 1, 2 are polymerized upper and lower supports,
The upper and lower supports are formed by forming the mating surfaces 3 and 4 in an arc-shaped curve and superposed. Further, the polymerized upper and lower supports are provided side by side with an appropriate interval. Reference numerals 5 and 6 are grip shafts that connect the upper support bodies that are arranged side by side, and reference numerals 7 and 8 are grip shafts that connect the lower support bodies. The grip shaft is pivotally fitted between the upper and lower supports by interposing a roller shaft 16 on the grip fixed shaft 10 shown in FIG. Reference numeral 9 is a fixed nut of the grip fixed shaft. Reference numerals 11 and 12 denote reinforcing shafts connected to the middle of the upper and lower supports 1 and 2 and serve to reinforce the body. 13, 1
4 is a gripping shaft between the upper and lower supports 1 and 2 which are polymerized, shafts 5, 6 and 7,
A link rod pivotally attached to 8 is connected in a vertical cross shape to be integrated. Therefore, the superposed upper and lower supports swing by the curved mating surfaces when a force is applied to the grip shaft. Reference numeral 15 is an elastic cushioning cloth that protects a finger from scratching or the like.

Next, in the second embodiment, as shown in FIG. 4, a board 20 or 21 having the same shape and having an appropriate width for hanging the fingertip is piled up and down with an instrument for training the gripping force of the fingertip. The superposed mating surfaces 22 and 23 are formed into arc-shaped curves as in the first aspect of the invention so that they can swing. The both ends of the upper and lower boards are finger hooks 24 of a shape that does not come off easily so that thumbs and four fingers can be easily hooked,
25 is provided. Insert the mounting shafts 26 and 27 into the finger hooks,
A cross rod is pivotally attached to the mounting shaft between the upper and lower plate bodies in which the link rods 28 and 29 are superposed. The upper and lower plates are integrally connected by the link rod and can swing right and left. In the embodiment of claim 1 for training both fingers, a space is formed between the gripping shafts so that the gripping shafts are rotatable and the gripping force can be easily applied to the entire fingers. It can be used as a gripping device for fingertips if it is attached to the attachment so that it does not rotate.

In the third embodiment, the grip shafts 32, 33, 3 are provided.
4, 35 are respectively connected between upper and lower supports 30 and 31 of arbitrary shape, and link rods 39 and 40 are provided between the upper and lower grip shafts.
The support is swingable by the gripping force of both hands. The grip shaft is rotatably attached to a grip fixed shaft 36 provided inside. Reference numeral 37 is a reinforcing shaft of the body, and 41 is a cushioning material for contact with fingers when gripping force.

The above is an embodiment of the gripping device for the hand and the gripping device for the fingertip, but the support which is vertically laminated is either a circular arc-shaped mating curve or a non-matting support. In addition, the material is a corrosion-resistant light metal or a strong synthetic resin body, and other materials having strength, lightness, and moldability are appropriately designed and configured according to the implementation situation. For example, in a hand gripping device, if the rotation of the grip shaft is fixed, it can be used as a device with a stronger load. A grip force meter may be appropriately set on the support or the top surface of the board, or the entire device may be a colored device. The gripping force device of claim 1 can be used as the gripping force device of claim 2 by fixing the grip shaft with a cover or an attachment.

[0010]

[Effect] As described above, the present invention has been newly developed as a gripping force tool that uses both hands. Since the gripping force is strengthened by gripping with both hands or by applying finger pressure to each other to rock the gripping force, Compared to this, one gripping force device can be used to train both fingers and fingertips at the same time, and the strength of the gripping force can be infinitely strengthened if freely changed by utilizing the gripping force of both fingers on the grip axis. . We were able to train a gripping device with only fingertips, which was unprecedented, and the functionality of the device was improved. Therefore, there is an advantage that it can be used for various sports, or as a tool for training fingertips of children and students who do not use chopsticks these days, and as a tool for improving the health of the elderly and the like.
