Description

The utility model relates to the field of sports equipment and devices for physical exercises and can be used to calculate the number of completed push-ups from the floor.

A device for controlling push-ups from the floor (Pat. 59983 Russian Federation, IPC ⁸ A63B 21/00. Device for controlling push-ups from the floor [Text] / Prokopyev N.Ya., Prokopyev A.N., Shabelyanskaya O.F .; applicant and patent holder of GOU VPO "Tyumen State University. Application. May 10, 2006; publ. January 10, 2007) containing articulated between two sites with a spring installed between them and electrical terminals connected to the light panel. The specified device signals the correct adoption of the lower position of the body with full bending of the hands.

A disadvantage of the known device is the lack of automatic calculation of the number of push-ups. Which leads to the ambiguity of the results of counting the number of push-ups in the performed and controlling. The described device has a disadvantage from the point of view of safety of the exercise. Since there is a peg on the top of the moving platform, you can be injured if you fall or quickly lower it.

The closest technical solution adopted for the prototype is a device for controlling the number of flexion and extension of the arms in the supine position (Pat. 111006 Russian Federation, IPC ⁸ А63В 21/00. Device for monitoring the number of flexion and extension of the arms in the supine position [Text] / Gauture I.A. et al .; applicant and patentee Federal State Military Educational Institution of Higher Professional Education "AFMozhaisky Military Space Academy" of the Ministry of Defense of the Russian Federation. Application. June 16, 2011; published on December 10, 2011), containing a fixed platform, mounted on it a vertical platform. At the upper end of the rack is a hinge connected to a movable platform. Between the movable and fixed platforms, on the base of the fixed platform, there is a spring and a limiter designed to limit the movement of the moving platform, an emitter and an optoelectronic key. An opaque curtain is fixed on the inside of the moving platform, placed in such a way that when lowering the moving platform, it falls into the target between the emitter and the optoelectronic key. When the arms are bent, pressure is applied by the chest on the moving platform to the limit. The pressure of the movable platform lowers the opaque curtain fixed to it, which, when the limiter touches the movable platform, gets into the target between the emitter and the optoelectronic key, blocks the beam, thereby changing the logical state at the output of the optoelectronic key. As a result, the value on the count indicator changes.

The disadvantages of the prototype are:

the wedge-shaped form of the device, which does not allow to ensure the independence of the result of the exercise when changing the point of contact of the chest pushing up with the moving platform of the device;

low reliability of the device, due to the significant number of elements that make up the device and located between two sites on which pressure is applied during the exercise.

An object of the invention is to increase the objectivity of counting the number of push-ups and increase the reliability of the device, by reducing the number of various elements located between the movable and fixed platforms.

The solution to this problem is achieved by the fact that the device for fixing the number of push-ups from the floor is a movable and fixed plate located parallel to each other. Microswitches without fixation are mounted in the corners of the fixed plate, connected in parallel and providing: signal generation when touching the moving platform, damping of the load when touching, and also returning the device to the standby state when removing the load on the moving platform. The inputs and outputs of the microswitches are connected to a power source and an indication unit, providing light, sound and digital indication when performing push-ups from the floor.

Thanks to the new combination of features, the claimed device allows to provide a higher level of objectivity when monitoring the implementation of push-ups from the floor. What is achieved by reducing the thickness of the device and ensuring independence of fixation of the exercise from the point of contact with the plane of the moving platform due to the flat shape of the device. The reliability of the device is achieved by providing the function of fixing the touch of the movable platform due to the smaller number of elements with a higher reliability coefficient (due to the parallel microswitch connection circuit).

The analysis of the prior art made it possible to establish that analogues that are characterized by a combination of features that are identical to all the features of the claimed technical solution are absent, which indicates compliance of the claimed device with the patentability condition “novelty”.

The structural diagram of a device for controlling push-ups from the floor is presented in figure 1.

The device comprises a fixed platform 1, a movable platform 2, fastened together by brackets 3 made of flexible material. In the recesses of the platform 1, along the perimeter, microswitches are mounted without fixing 4 connected in parallel. The outputs of the microswitches 4 are connected to the inputs of the digital, light and sound indications block made according to the well-known scheme (for example, described in Pat. 111006 Russian Federation IPC ⁶ А63В 21/00. Device for monitoring the number of bending and unbending arms in a lying position [Text] / Gotur I.A. et al .; applicant and patentee Federal State Military Educational Institution of Higher Professional Education "AF Mozhaisky Military Space Academy" of the Ministry of Defense of the Russian Federation. Application. June 16, 2011; publ. 1 12/01/2011).

The device operates as follows. The controlled person bends the arms until it contacts the movable platform 2. Due to the impact on the platform 2, at least one of the microswitches 4 connected in parallel is closed. The signal from the outputs of the microswitches 4 is fed to the inputs of the display unit 5, as a result of which there is a light, sound and digital indication of the exercise. The fixation of the movable platform 2 relative to the stationary platform 1 provide staples made of flexible material.

When the arms are extended, the load from the pad 2 is removed, as a result of which the microswitches 4 open due to the springs built into them, the light, sound indication stops, and the value of the digital indication increases by a single value. After which the cycle can be repeated as many times as necessary.

This device allows you to eliminate the contentious moment between the performed and the controlling when calculating the number of push-ups. Provides a greater degree of approximation to the requirement of push-ups "from the floor", by reducing the thickness of the device. Allows to provide an indication with equal pressing force anywhere in the moving platform.
