Description

The device relates to sports equipment and is designed to develop the strength of the muscles of the shoulder girdle and to develop the skill of performing a direct strike by athletes involved, in particular, martial arts.

Currently, a number of simulators for the shoulder girdle are known to strengthen and develop muscle strength when doing push-ups from horizontal surfaces.

Known training kit (patent RU 51514 U1 02.27.2006), an analog, in the form of two identical devices, each of which consists of two cases in the form of disks, covered with a layer of elastic material and interconnected by a bearing.

The disadvantages of this device include a constructive solution for connecting the housings using a rolling bearing. Such a connection implies the presence of a relatively large diameter in the design of the bearing with the outer and inner cages, sufficient for the stability to work without skewing and jamming under load. Bearing manufacture requires several operations on high-precision equipment.

A set of disk simulators is known (patent RU 127321 U1 04/27/2013), an analogue, each of which contains upper and lower housings equipped with a rotation axis and bearing assembly, while the supporting surfaces of the housings are covered with plates of elastic material.

This device has some drawbacks, in particular, it is not possible to use supporting planes in each of them with excellent hardness for pushing up athletes with different levels of preparedness for fists' shock surfaces.

A simulator was chosen as a prototype (patent RU 179343 U1 07/03/2017), which includes two cases in the form of disks fastening their axis, balls, and also plates made of elastic material with excellent hardness from each other. With all its simplicity and efficiency, this device does not provide for the possibility of push-ups on a supporting plane of solid material, which is a significant drawback, because It is widely practiced in martial arts, in particular karate.

The technical result achieved by the implementation of the claimed device is the expansion of its functionality as a result of using a combination of a support plane in it, both from elastic and solid materials for training athletes involved, in particular, martial arts.

To achieve a technical result, two devices are introduced into the device: disc-shaped housings that hold their axis together, balls placed in annular grooves and together constituting a bearing assembly, a plate of elastic material, a plate of hard material, and anti-slip bearings.

New distinctive nodes are a plate of solid material 6 and anti-slip supports 7.

In FIG. 1 is a cross-sectional diagram of a device that has the following functional elements.

1. Case.

2. The axis.

3. Plate made of elastic material.

4. Balls.

5. Ring grooves.

6. Plate made of hard material.

7. Support.

The cases 1 with the plates 3 and 6 placed on their surface are fastened by the axis 2 with the possibility of free rotation. The bearing assembly, consisting of balls 4, placed in the annular grooves 5 and evenly distributed in them, reduce the friction of the pair under load.

The operation of the device when performing exercises push-ups from a horizontal surface is as follows. Two identical devices are placed one under each user's hand. He installs the device on a horizontal surface at the necessary distance from one another, having previously turned to himself a supporting plane of the desired hardness. Then, putting 1 hands, clenched into fists, in the centers of the buildings 1, he assumes the position of “lying down”.

By bending and unbending the elbow joints, the trainee performs push-ups, while simultaneously turning his fists on the devices. When straightening the elbow joints, the athlete’s left fist rotates clockwise, and the right fist turns counterclockwise.

Under the action of the training force, the casing 1, located on top, rotates on the axis 2 relative to the lower casing 1 using a bearing assembly consisting of balls 4 placed in grooves 5. When the elbow joints are bent, the fists rotate in the opposite direction. Then the cycle repeats. For athletes with a sufficient level of training, push-ups on one arm are possible.

As a result, the trainee develops the skill of performing a direct hand strike, characteristic of most martial arts, in which a clenched fist rotates around its axis when the elbow joint is straightened. In martial arts, in particular, karate, push-ups from a horizontal hard surface on bare fists are widely practiced to strengthen their shock surfaces. For this, the claimed device provides a supporting plane of solid material.

In this case, an athlete with an injured or insufficiently prepared shock part of the fist may turn the device with the elastic plate up to perform the exercise.

In this case, in order to prevent slipping of the solid support plane, supports on it are made of elastic material made of separate elements, or in the form of a continuous collar, placed along the edge of the support plane, so that they do not interfere with the exercise. In this case, a plate of solid material can be structurally integral with the body.

The above distinguishes the claimed device from analogues and prototype and allows to achieve a technical result with a positive effect.

Implementation (for clarification only).

The claimed device is made using known materials (see Fig. 1).

Elements 1 are made of steel or impact-resistant plastic, elements 2, 4 are made of steel, element 3, 7 are made of rubber or silicone, elements 6 are made of plastic or wood. The device does not have other features.
