RU198554U1 - Step platform with the ability to fix the number of ascents - Google Patents

Abstract

The useful model relates to the field of medicine and physical culture, namely, to devices designed to determine the level of physical performance of a person and is aimed at facilitating the step test, due to the most accurate counting of ascents on the steps by the subjects and the possibility of quick access of the researcher to the data obtained. This is achieved by the fact that the device is represented by a mechanical counter installed on a tray, connected by means of a button to a platform, from which springs with rods extend, and the distal ends of the latter are immersed in the holes of the frame containing folds. The useful model can be used in the practice of teachers of physical culture, sports trainers, as well as persons engaged in research activities in this direction, when determining the level of a person's physical performance, in particular, using a step test.

Description

The useful model relates to the field of medicine and physical culture, namely, to devices designed to determine the level of physical performance of a person.

For an adequate assessment of physical performance, in particular, when using a step test, an extremely important indicator is the exact number of ascents made by the subject during the study.

Currently, various platforms are used to conduct a step test.

So, a set of different-height step platforms for carrying out functional load tests is known [Patent RU No. 2531873, publ. dated 10/27/2014], containing at least two step-platforms, characterized in that each of the subsequent step-platforms has geometric dimensions that are smaller than the previous one, while each of the step-platforms of the kit is made in the form of a hollow thin-walled truncated quadrangular pyramids.

Also known is a step platform for carrying out functional load tests [RU # 133707, publ. dated 10/27/2013], made in the form of a hollow thin-walled truncated quadrangular pyramid.

A common disadvantage of these devices is that when they are used to conduct functional tests, the researcher has to independently count the ascents, which can lead to errors in calculations, especially in mass studies, when several subjects climb onto the platforms at once.

Known device for determining the physical performance of a person [RU 140166, publ. from 04/27/2014], containing a unit for measuring heart rate (HR), an input unit of initial data, the first output of which is connected to the first input of the unit for determining physical performance, the outputs of which are connected to the information display unit, and the second input to the output of the tempo setting unit lifting, as well as a serially connected digital accelerometer and a signal preprocessing unit, a unit for setting the rate of ascent, connected by the first input to the second output of the initial data input unit connected to the second input of the signal preprocessing unit, characterized in that it is equipped with a unit for calculating the critical heart rate level , a comparison unit, four registers, an initial data processing unit, an OR logical block and a step platform with a variable step height equipped with a drive, while the input of the critical heart rate calculation unit is connected to the first output of the input data input unit, and its output is connected to the first comparison block input, second input ohm connected to the output of the heart rate measurement unit and the first inputs of the first and second registers, the second inputs of which are connected to the first and second outputs of the ascent rate setting block, also connected respectively to the second inputs of the first, second, third and fourth registers, to the third and fourth inputs of the block signal preprocessing, the output of which is connected to the first inputs of the third and fourth registers, while the register outputs are connected to the corresponding inputs of the unit for determining physical performance, the output of the first register is connected to the second input of the initial information processing unit, the input connected to the output of the initial data processing unit, and two outputs connected to the information display unit, to the fourth and fifth inputs of the physical health determination unit and to the step platform drive, the OR logic block is connected by the first input to the first input of the lifting rate setting block, the second input to the output of the comparison unit, and the output - with the third input of the block for setting the rate of rise.

The disadvantage of this device is the complexity of its implementation and use (the need to use additional heart rate monitors), the requirement from the researcher to use skills (teaching to work) this device, as well as the presence of a constant power supply, which is difficult when carrying out functional tests in the gym.

The closest to the claimed device and selected as a prototype is a step-platform with the function of self-counting ascents [RU # 195126, publ. 15.01.20], characterized in that it contains a mechanical counter connected by means of a button to the platform, from which the springs with rods extend, and the distal ends of the latter are immersed in the holes of the frame.

The disadvantage of this platform is the inability to quickly view the counter values, since the latter is not able to move out, and therefore, when using this device in an experiment, the researcher often neglects the counter values and calculates independently, which, in turn, can lead to inaccuracies and errors in assessing physical performance.

The purpose of the utility model is to create an easy-to-use and easy-to-use platform that facilitates the step test, due to the most accurate calculation of the ascents of the steps by the subjects and the possibility of quick access of the researcher to the data obtained.

The technical result of this goal is achieved by creating a device, represented by a mechanical counter 1 installed on a tray 8, connected by means of a button 2 to a platform 3, from which springs 4 depart with rods 5, and the distal ends of the latter are immersed in the holes 6 of the frame 7 containing folds 9.

In FIG. 1 shows a general view of the utility model.

In FIG. 2 shows a top view of the bed 7 without platform 3.

In FIG. 3 shows a top view of the assembly with Tray 8 pulled out.

The utility model is used as follows.

To carry out the step test, the researcher marks the time on the stopwatch and gives the command to the researcher, who begins to step onto platform 3, which, under the weight of a person, drops down so much that he presses button 2 of counter 1, due to which a reliable count of the number of ascents is carried out.

After lowering the subject from platform 3, it rises due to the expansion of springs 4, and its displacement is prevented by rods 5 immersed in holes 6 of the bed 7.

Upon completion of the test and there is a need to view the number of ascents, tray 8, sliding along its pressed folds 9, is pushed out by the researcher beyond platform 3 by so much that the values of counter 1 become visible.

The positive effect of the claimed technical solution consists not only in ease of use, but also in facilitating the step test, through the most accurate counting of the ascents to the platform by the subjects, due to the presence of a mechanical counter, with the possibility of its extension.
