RU59983U1 - DEVICE FOR CONTROLLING DEPRESSIONS FROM THE FLOOR - Google Patents

Abstract

The utility model relates to the field of medicine and medical technology, namely to devices designed to control the number of push-ups from the floor. The utility model is a device consisting of a base 1 and made in the form of a keel of a movable platform 2 connected by a piano hinge 3. On the opposite side of the piano hinge 3 of the base 1 are metal terminals 4 with an electric wire 5 to the digital display 6. On the top of the movable platform 2, a removable marked peg 7 is placed, metal terminals 4 are located on the bottom. An electric wire 5 departs from each of the terminals to the light of the light panel 6, which ensures precise numerical control of ETS pushups. Depending on the functionality and physical condition of the subject, the removable marked peg 7 may be of various lengths. Between the base 1 and the movable platform 2, a spring 8 is installed, which prevents the terminal 4 of the device from being inoperative. A utility model may find application in physical education to control the number of pushups from the floor.

Description

The utility model relates to the field of medicine and medical technology, namely to devices designed to control the number of push-ups from the floor in the supine position.

The purpose of the utility model is to monitor, during physical education and sports, the exact observance of the number of push-ups from the floor in the supine position.

A device [1] is known for monitoring the bending-extension of the arms in a supine position, made in the form of a base and a movable plate, upon contact of which an electrical circuit is closed with the supply of a light signal to the display. The disadvantages of this device are:

- the presence of a wide mobile platform, not always corresponding to the transverse dimensions of the chest of the test person, which complicates the use of the device in children;

- the lack of dosing of the degree of flexion in the elbow joint without taking into account the functional state of the human body as a whole and the elbow joint in particular.

A device [2] is known, which is a protractor with a diameter of 20-30 cm, to which a radius rotating around an axis is attached. The protractor is placed externally along the axis of the shoulder at the level of the elbow joint and the angle of movement of the joint is noted by the deviation of the radius. The disadvantage of this device is its bulkiness.

It is also known [3] a goniometer device having two equal lengths of movable branches extending from the protractor. The goniometer jaws are arbitrarily set at the level of the elbow joint along the axis of the shoulder and forearm, while the protractor determines the range of movements in the elbow joint.

The objective of the utility model is to monitor the number of push-ups from the floor in an upright position by athletes and athletes.

The problem is solved by using a technical device (Fig. 1) made of wood of the base 1 and the movable keel-shaped platform 2, connected by the piano hinge 3. On the opposite side of the piano hinge 3 of the base 1 and the movable platform 2, metal terminals 4 are installed with an electric wire 5 to the digital display 6. The movable keel-shaped platform 2 in its upper narrow part is represented by a removable round graduated peg 7. From each of the terminals 4 to the light of the light display 6 there is an electric rovod 5 that provides precise control of the amount of push-ups from the floor. The length of the graded peg 7 is selected individually depending on the anatomical and functional capabilities of the student (age, arm length, degree of development of the muscular system of the upper limb and trunk, sports record, magnitude of flexion-extensor movements in the elbow joint) and can be different (from 3 to 15 cm).

Between the base 1 and the movable platform 2, a spring 8 is installed, which prevents the contact of the terminals 4 in the inoperative state of the device.

Figure 1 shows a general view of a utility model.

The utility model works as follows. The subject takes the initial position of "lying hands at rest", while the device is located between the hands under the chest. When conducting flexion movements in the elbow joint, the front surface of the subject’s chest touches the top of the peg 7 of the keel-shaped movable platform 2. Under light pressure of the chest on the peg 7, the spring 8 is compressed, resulting in the contact of the metal terminals 4 of the base 1 and the movable platform 2. Electrical the circuit closes and wire 5 passes the signal to the light bulb 6.

Depending on the degree of training and functional capabilities of the test subject, the length of the removable peg 7 of the movable platform 2 can be reduced or increased, which is achieved by screwing the peg more or less (1 cm) in length. The control of the number of push-ups from the floor in the supine position is always carried out individually. At the stage of initial preparation, i.e. with poor physical fitness of the test subject, the length of the peg 7 is longer, for example, 15 cm, which ensures less physical activity when performing the exercise. In process of fitness of a sportsman or athlete, i.e. increasing its functionality, to create a higher physical load, the length of the peg 7 is reduced. Thus, a decrease in the length of the peg 7 indirectly indicates an increase in the functional capabilities of the subject.
