RU176953U1 - Device for controlling pull-ups - Google Patents

Abstract

The testing of this utility model in the educational process at physical education lessons, conducted in some Moscow schools, confirmed our assumptions about the need to create a device that would objectively evaluate the clarity and correctness of students performing the “torso lifting” exercise. As a result of this experiment, students began to perform the exercise more faithfully. The development of standards for this type of test for the new TRP Complex based on the use of the proposed model for "raising the torso" will avoid conflicts, protests, etc. when performing this exercise. The use of this device in one of the types of programs of the new TRP Complex will help to objectively and more fairly assess the level of physical preparation of those who pass the standards for all those who pass, and, especially, applicants for admission to universities that count on additional preferential points. 1 ill.

Description

            Exercise “pulling up on a high crossbar” is one of the main types of the TRP Complex, reflecting the level of physical development of the male population of the Russian Federation.

Using the utility model is aimed at developing the muscles of the hands, but the result of the quality of the exercise is evaluated visually. Such an assessment, being subjective, can cause various interpretations of the correctness of the exercise in the form of conflicts, protests, etc. To prevent such excesses, this utility model was created.

There are a number of patented devices based on a single principle of connecting the contacts of an electric circuit when the exercise is performed correctly.

Utility model (RU 111006) for controlling push-ups from the floor. The main disadvantages of the device should be considered the technical complexity of the design and the use of household electrical voltage, which can pose a threat to the life and health of the student.

Utility model (RU 120572 U1). A useful model for controlling push-ups is a complex device, the design of which uses electric wires, plates worn on the chest, a conductive belt, etc., which can be a serious danger.

Utility model (RU 150438 U1). Device for controlling push-ups. Disadvantages: work only on solar panels using batteries.

Utility model (RU 123678 U1). Disadvantages: the sensors work only when all four microswitches located at the corners between two parallel platforms, one of which is movable, are connected simultaneously.

All of these devices are based on determining the correctness of the physical exercise, provided that the contacts of the electric circuit are connected using mains power or direct current elements, wires, connectors and a light indicator.

The basis of this utility model is a part of a pipe (1) of non-metallic material with a diameter close to the diameter of the crossbar (7). A thin flexible plate (3) is fixed on it with non-metallic rivets (2), to which an insulated electric wire is connected leading to the LED (4) and then to the power supply unit (5) with a voltage of 3 v. From the power supply through another wire, the voltage passes to the mass of the crossbar. The utility model is mounted on the crossbar using two clamps (6) so that the uninsulated edge of the flexible plate is located along the crossbar at a distance of 1-2 mm from it.

The essence of this utility model is the ability to determine the quality of the exercise “pulling up on a high crossbar” based on the use of a compact, easy to manufacture, safe device that allows you to control the exercise by pressing the chin on top of the flexible plate of the body until it touches the crossbar, as a result which closes the contacts, forming an electric circuit, and the indicator lights up, notifying others about the exercise tions.

Technical solution

The basis of the technical solution is to determine the correct implementation of pull-ups on a high crossbar.

The device consists of two parts: an insulated casing with a flexible plate, a power supply unit consisting of two DC batteries, light indication and wires connecting both parts of the device. The device is mounted on the crossbar with clamps on both sides, forming a single compact product. The upper and lower parts of the housing surfaces are insulated, except for the flexible part, which is designed to touch the crossbar during the exercise.

Claims (1)

A device for controlling pull-ups, consisting of a crossbar with an element installed in it in the form of a part of a pipe made of non-metallic material, with a diameter close to the diameter of the crossbar, onto which a thin flexible plate is fixed with non-metallic rivets, to which an insulated electric wire is connected leading to the LED and further on the power supply, from the power supply, through another wire, the voltage goes to the crossbar, while part of the pipe is fixed to the crossbar using two clamps.
