Abstract

Usage: to strengthen and develop the strength of the muscles of the shoulder girdle of athletes involved, in particular, martial arts. Technical result: reducing the cost of manufacturing devices, increasing comfort and versatility of use. The essence of the utility model: contains two disks 1 with plates 2, axis 3, balls 4, annular grooves 5 and supports 6. The disk 1, located on top, with a plate 2 mounted on it, performs the twisting movements while practicing push-up exercises by the trainee with a twisted brush, clenched in fists eniya relative to the lower disc 1 around its axis 3. The fastening plate 2 uniformly distributes force on the striking surface knuckle. Balls 4 placed in the annular grooves 5 reduce the friction of the pair under load. The supports 6, which are integral with the plate 2, prevent the device from slipping and provide stability on a flat surface. Positive result: expanding the area of use. 1 ill.

Description

The device relates to sports equipment and is intended to strengthen and develop the strength of the muscles of the shoulder girdle of athletes involved, in particular, martial arts.

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

A well-known training kit (patent RU 51514 U1 02.27.2006) is an analogue, 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 discs using a bearing. This connection assumes the presence in the design of the bearing with outer and inner bearings with a diameter sufficient to ensure stability without distortion and jamming under load. This solution significantly increases the cost of manufacturing the device.

As a prototype, a set of disk training machines was selected (patent RU 127321 U1 04/27/2013), each of which contains upper and lower housings equipped with a rotation axis and a bearing assembly, while the supporting planes of the housings are covered with plates of elastic material.

With the simplicity and efficiency of the design, this device has some disadvantages. Since elastic plates have a flat surface without supports, when placed on a rough surface they can lose stability, the support plane is subject to contamination and the incorporation of solid particles such as grains of sand and small pebbles into it.

In addition, it is not possible to use elastic plates with excellent hardness in one device for pushing up athletes with a different level of training of shock surfaces of fists.

The technical result achieved by the implementation of the claimed device is to reduce the cost of production and increase comfort and versatility of use.

To achieve a technical result, two disks are introduced into the device, fastening their axis, balls placed in annular grooves and evenly distributed in them, plates made of elastic material with supports made on their surface.

New distinctive nodes are plates made of elastic material 2 with supports 3 made on their surface in the form of separate protrusions or a continuous bead, as well as the difference between one plate and the second in terms of its mechanical properties, in particular hardness.

The claimed device is illustrated by the description and drawings. In FIG. 1 is a cross-sectional diagram of a device that has the following functional elements.

1. Disks

2. Plates

3. Axis

4. Balls

5. Ring grooves

6. Supports.

Disks 1 with plates 2 placed on their surface are fastened by an axis 3 with the possibility of free rotation. The balls 4 are placed in the annular grooves 5 and evenly distributed in them, which reduces the friction of the pair under load. Supports 6 prevent slipping of the device, and also provide a stable position on an uneven surface.

The operation of the device when performing exercises push-ups from a horizontal surface is as follows. In this case, it is supposed to use two identical devices located one under each arm of the trainee. He installs the device on a horizontal surface at the distance he needs from one another, having previously turned to himself a plate of the required hardness. Then, putting 1 hands in the centers of the discs, clenched into fists, with the back sides outward, and palms facing each other, he assumes the position of “lying down” on bent arms. When the trainee moves from this position to the “lying down” position on straight arms, his elbow joints are straightened with synchronous turns of the fists — left clockwise and right counterclockwise.

Under the action of the training force, the disk 1, located on top, makes rotational movements on the axis 3 relative to the lower disk 1 using balls 4, which reduce friction under load. Then the cycle repeats.

As a result, the practitioner 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. An elastic plate of the required hardness has a strengthening effect on the striking surface of the training fists.

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

Implementation (for clarification only).

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

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