Abstract

 A device for training hands containing a wrist grip with a base in the lower part to which a load is attached, and a device for connecting a wrist grip and a load, characterized in that the device for connecting a wrist grip and a load is made in the form of a ball mounted in the cavity of the wrist base grip, and thrust connecting this ball and the load, and the lower part of the base of the wrist grip has a support hemisphere in which the ball of the device connecting the wrist grip and the load is located.

Description

The utility model relates to the field of sports, in particular to devices for training hands in athletes.

A device for training wrestlers is known, containing a wrist grip, to the lower end of which a load is attached, see A.S. No. 1713606 [1].

The disadvantage of this device is its limited functionality.

A device for training wrestlers is also known, containing a wrist grip with a base in the lower part to which a load is attached, and a device for connecting a wrist grip and a load, see A.S. No. 1741826 [2].

The disadvantage of this device is its complexity, the mechanism for connecting the wrist grip and the load is cumbersome and has limited functionality due to the fact that during use the load carries out only oscillatory movements in one plane relative to the wrist grip, this dramatically reduces the effectiveness of the training effect of the known device. The bulkiness of the device makes it inconvenient to use.

The technical result of the proposed device is to increase the efficiency of training hands and expand the ability to use it by athletes with different levels of training.

The technical result is achieved by the implementation of the device for connecting the wrist grip and the load in the form of a ball mounted in the cavity of the base of the wrist grip, and the rod connecting the ball and the load, and the lower part of the base of the wrist grip in the form of a support hemisphere in which the ball of the device connecting the wrist capture and cargo.

Figure 1 shows a device for training hands.

A device for training hands contains a wrist grip 1 with a base 2 in the lower part, to which the load 3 is attached.

A device for connecting the hand grip 1 and the load 3 is made in the form of a ball 4 mounted in the cavity 5 of the base 2 of the hand grip 1, and a rod 6 connecting the ball 4 and the load 3.

In the lower part of the cavity 5 of the base 2 of the wrist grip 1 there is a support hemisphere 7 in which the ball 4 of the device connecting the wrist grip 1 and the load 3 is located.

In the lower part of the hemisphere 7, a hole 8 is made in which the rod 6 is located.

In the hole 8, which has a diametrical section in a conical shape, an annular elastic element 9 is installed, for example of rubber, damping interactions with the rod 6.

Hand grip 1 has a conical shape and is connected to the base 2 by a threaded connection 10.

The load 3 is made with a cavity 11, which serves to increase the weight of the load 3 by filling it, for example, with water, and equipped with a plug 12. The rod 6 is connected to the load 3 with a threaded connection 13.

To assemble the device for training hands, first set the ball 4 in the base 2, which is disconnected from the grip 1. Then screw the grip 1 onto the base 2, and the rod 6 is screwed to the load through the threaded connection 13. The cavity 11 of the load 3 is filled with water and screwed plug 12. The device is ready for use.

The device is used as follows.

Depending on the person’s preparedness for training hands, cavity 11 is filled with the required amount of water. Then the athlete grabs the wrist grip 1 and raises the device for training the hands, holding it on weight. After that, the athlete begins to rotate his hand with a certain frequency, as a result of which the load 3 begins to make rotational movements relative to the vertical axis of the wrist grip 1.

The rotation of the load 3 leads to the appearance of centrifugal forces, the impact on the ball 4 and the wrist grip 1. In this case, the elastic element 9 on the one hand limits the amount of displacement of the load 3 relative to the axis of the wrist grip 1, on the other hand, dampens the forces of interaction of the thrust 6. increases in fitness of the hands increase the weight of the load 3, adding water to it, and increase the frequency of rotation of the load 3 relative to the vertical axis of the wrist grip 1.

From the frequency of rotation of the load 3, from the radius by which the center of gravity of the load 3 is shifted from the vertical axis of the wrist grip 1, from the force of the weight of the load 3 and from the forces arising from the rotation of the load 3, offset from the vertical axis of the wrist grip 1, the magnitude of the loads depends perceived by the hands. The training process is intensified due to these values, as well as due to the gradual increase in the frequency of rotation of the load 3 relative to the axis of the wrist grip 1.

All this together gives a synergistic effect that increases the effectiveness of training hands. At the same time, the device is compact and convenient for its use by both athletes and people with different levels of training.
