Abstract

FIELD: medicine.

SUBSTANCE: vacuum press machine relates to sports inventory and is intended for development of human muscle mass. Vacuum press machine consists of frame. The following components are fixed on frame: guide units; force controller with switching levers; vacuum elastic element. Vacuum elastic element consists of pipe. Edge of pipe is arranged as tight. Inside pipe there is a piston with rubber seals and cord that connects piston with force controller. Vacuum pump and valve are installed at tight edge of pipe. Cord comes out from force controller, passes through guide units and is fixed on handle.

EFFECT: lower material intensity due to exclusion of weights and application of force controller in vacuum press machine design makes it possible to vary force of counteraction to muscle force of a person within a wide range.

Description

Technical field

The vacuum power simulator belongs to sports equipment. Designed for the development of muscle mass.

State of the art

In modern power simulators to create a counteraction to human muscle strength, we use: weights, springs, rubber tows, hydraulic cylinders.

SUMMARY OF THE INVENTION

The use of a vacuum elastic element in power simulators instead of weights, springs, rubber bands, hydraulic cylinders. Creating a new type of weight training equipment. The vacuum elastic element is known from Patent RU No. 2229452 "Spring Vacuum block throwing weapon"

Technical result

When designing the "Vacuum-block throwing weapon" we discovered the following phenomenon: "the pressure force of atmospheric air on the piston is constant (constanta) at any point on the piston."

The generally accepted average pressure force of the atmosphere is 1.06 kg / cm ² . A vacuum power simulator, on which a vacuum elastic element (weight 5-10 kg) with a piston diameter of 20 cm, is installed, creates a counteraction to human muscle strength = 333 kg (constanta).

The use of a force regulator in the design of a vacuum power simulator allows you to change the counteraction force of a person’s muscle strength over a wide range.

Possessing all the useful characteristics of a weight trainer, the vacuum trainer is several times lighter in weight. The simulator is compact, mobile.

Brief Description of the Drawings

The design of the claimed invention is illustrated by the following drawings:

Figure 1 is a side view of a vacuum power trainer (static position).

Figure 2 is a side view of a vacuum power trainer (in dynamics).

The device of the vacuum power simulator.

The vacuum power simulator consists of a frame 1 (figure 1; 2). On the frame are fixed: guide blocks 2 (Fig. 1; 2); force regulator 5 (Fig. 1; 2) with shift levers 6 (Fig. 1; 2); vacuum elastic element. The vacuum elastic element consists of a pipe 7 (figure 1; 2). The edge of the pipe is sealed. Inside the pipe 7 (Fig. 1; 2) there is a piston 8 (Fig. 1; 2) with rubber seals and a cable 3 (Fig. 1; 2) connecting the piston 8 to the force regulator 5 (Fig. 1; 2). On the sealed edge of the pipe 7 (Fig. 1; 2), a valve 9 (Fig. 1; 2) is fixed, to which a vacuum pump 10 (Fig. 1; 2) is connected. A cable 12 (Fig. 1; 2) comes out of the force regulator 5 (Fig. 1; 2), passes through the guide blocks 2 (Fig. 1; 2) and is mounted on the handle 4 (Fig. 1; 2).

Work of a vacuum power simulator.

The vacuum power simulator uses the principle of gas pressure difference. In this case, the force of atmospheric pressure is used.

Levers 6 (Fig. 1; 2) of the force regulator 5 (Fig. 1; 2) set the necessary counteraction force. When muscle power is applied, which corresponds to the settings of the force regulator 5 (Fig. 1; 2), on the handle 4 (Fig. 1; 2), the cable 12 (Fig. 1; 2) passing through the movable blocks 2 (Fig. 1; 2) interacts with a cable 3 (Fig. 1; 2) through a force regulator 5 (Fig. 1; 2). The cable 3 (figure 1; 2) pulls the piston 8 (figure 1; 2). The movement of the piston 8 (figure 1; 2) is counteracted by atmospheric pressure. The pressure force of the atmosphere on the piston 8 (Fig.1; 2) is constant (constanta) at any point of movement (location) of the piston. When the piston 8 (Fig. 1; 2) moves, the volume of the vacuum chamber inside the pipe 7 (Fig. 1; 2) increases. During operation of the vacuum elastic element, a small amount of air may form in the vacuum chamber. Air removal is carried out using a vacuum pump 10 (figure 1; 2) through valve 9 (figure 1; 2).
