RU171257U1 - Complex for measuring amplitude when squatting an athlete with a barbell on his shoulders - Google Patents

Abstract

Usage: electrical appliances, as well as measuring the amplitude when performing exercises squats with a barbell on the shoulders of an athlete powerlifter in competitions or in preparation for competitions. Technical problem: providing the user-athlete, judges of the competition with a simple design and maintenance system that allows you to measure the amplitude when an athlete performs squats with a barbell on his shoulders. The essence of the utility model: a complex for measuring amplitude when squatting an athlete with a barbell on his shoulders includes: a stick "Selfie" is equipped on one side with an ultrasonic rangefinder HC-SR04 and Wi-Fi transmitter (adapter), fastener (bracket) for fastening to a belt on the other side. Technical result: the complex allows the athlete to independently measure the amplitude ("depth") in the squat exercise with a barbell on his shoulders and receive objective data on external electronic devices in real time.

Description

The utility model relates to electrical measuring devices and can be used as a means of objective control when squatting with a barbell on the shoulders of an athlete-powerlifter both during regular training and in competitions in such a sport as powerlifting. Known ultrasonic rangefinder HC-SR04 [Electronic resource] /http://avrproject.ru/publ/kak_podkljuchit/ultrasonic_sonar_hc_sr04/2-1-0-51. An electronic device is a module with two piezoelectric emitters, one of which serves as an emitter, and the second as an ultrasonic wave receiver, a microcontroller, and a liquid crystal display for outputting measured readings. For connection, the module has a 4-pin connector: two contacts for power (5 volts are required), and two more for communication with the microcontroller.

The above analogue is the closest in technical essence to the claimed technical solution, therefore, selected for the prototype.

The design of the analogue prototype has disadvantages.

Firstly, the athlete is not able to independently measure the amplitude when performing exercises - squats with a barbell on his shoulders.

Secondly, the measured data is displayed only on the liquid crystal display.

Thirdly, the ultrasonic rangefinder does not have an autonomous power source.

The indicated disadvantages of the prototype analogue can be eliminated by the proposed utility model, the main value of which is to provide the user with a “Complex for measuring the amplitude of an athlete’s squats with a barbell on his shoulders” (ie, the “depth” of squats with a barbell on his shoulders). The utility model allows to achieve a technical result, namely:

1. Measure the amplitude of the exercise - squats with a barbell on the shoulders.

2. Receive data in real time, on external electronic devices (computer, laptop).

3. Does not require additional special equipment, has an autonomous power source.

The complex for measuring amplitude when squatting an athlete with a barbell on his shoulders (hereinafter referred to as the complex) includes:

- HC-SR04 ultrasonic rangefinder, consisting of:

- piezo emitters HC-SR04 with effective viewing angle <15 °

- microcontroller ATMEGA8

- LCD 16 * 2 Sonar HC-SR04

- power supply with technical specifications: supply voltage 5V, quiescent current <2 mA

range of distances 2-500 cm, resolution 0.3 cm;

- adapter class Wi-Fi transmitter, designed to transfer information to external electronic devices (computer, laptop);

- a device for fastening in the form of a selfie stick, equipped on one side with a range finder with a Wi-Fi transmitter, and on the other hand, with a fastener (metal bracket of sufficient rigidity) for fastening to a belt;

- a computer program (client application) installed in external electronic devices for recording and processing results in real time.

The principle of operation of the complex is based on the simultaneous interaction of its components with the output of information to external electronic devices via a Wi-Fi adapter. In addition, special requirements are imposed on the floor surface: it should not have a fleecy coating.

The complex operates under the control of special software in the following mode:

1. Before turning on, the complex is fixed on the belt of the athlete-powerlifter (preferably at the back), adjusting the range finder so that a perpendicular line is provided between the ultrasonic range finder and the floor surface.

2. Turn on the measuring complex with a Wi-Fi transmitter.

3. Turn on the computer or laptop and establish communication with the measuring complex via the Wi-Fi channel.

4. Run a computer program (client application) that captures the measured amplitude.

5. Before the competition, a powerlifter performs a squat with a bar from a bar without discs, in which the upper parts of the surfaces of the legs at the hip joints will be at the same level horizontally with the tops of the knees. The control amplitude is measured, data is output and stored in the computer.

6. The athlete performs a squat with a barbell on his shoulders, in which the upper parts of the surfaces of the legs at the hip joints will be lower than the tops of the knees. Only with such a performance exercise is counted in the competition.

7. The range finder in the complex measures the amplitude of the exercise by the athlete and displays data on a computer or laptop in real time. If the obtained amplitude is less than the control, then the exercise is considered performed correctly and is counted.

Thus, the design of the complex allows you to effectively measure the amplitude when squats with a barbell on your shoulders, in a sport such as powerlifting, in competitions or in preparation for competitions.

With the help of this complex, judges, jury members, coaches and athletes will be able to obtain objective data (up to millimeters) about doing squats with a barbell on their shoulders during training or at the competitions themselves in real time.
