The invention relates to sports training equipment and can be used for training athletes and athletes.

The purpose of the invention is to improve ease of use.

FIG. 1 shows the device in the first initial position of the exit arm, a vertical longitudinal section; in fig. 2 - the same during the transition period; in fig. 3 - the same, in the second initial position of the output handle.

The device comprises a frame 1 on which a working pulley 2 and a bypass pulley 3 are mounted for free rotation. A cable 4 attached through the bypass pulley 3 is attached to the peripheral point of the working pulley 2, and the tension load 5 attached to the other end of the cable 4 the possibility of free vertical displacement, for example, in the sleeve 6, attached to the top load 7 pack of cargoes B. On the working pulley 2 there are two counterweights 9 and 10, the weight moments of which are shifted in phase of rotation of the pulley 2 by 90 °, i.e. counterweights mustache mounted on pulley 2 at an angle to one another, at 90 °. The weight moment from the center of the body of each of the counterweights 9 and 10 pa of the radius of its installation on the pulley 2 is larger than the weight moment of the tension load 5 on the radius of the pulley 3. At the same time, the attachment point of the cable 4 to the pulley 2 is the hinge 11 (point A in Fig. 1), the length of the cable is determined by the vertical position of the counterweight 10, and above the axis of rotation of the pulley 2, and the horizontal position of the counterweight 9 with the upper thrust position of the tension load 5 in the sleeve 6. The geometries of the position of the pulleys 2 and 3 are determined from that with the same top In a fixed position of the tension load 5, the hinge 11 occupies a position (point B in FIG. 3), in which, on the contrary, the counterweight 10 occupies a horizontal position, and the counterweight 9 - the upper vertical position. From the layout of the device, the angle between the axles of the pulleys 2 and 3 and the horizon is about 40 °. With this geometry, the position of the counterweights 9 and 10 and the attachment point of the cable 4 on the pulley 2 in the lower position of the tension load 5 in the sleeve 6, the pulley 2 takes the position in which the attachment point (point B in Fig. 2) is on the right side mine, the tangential circumference of the bypass pulley and the working pulley 2 moving through the axis of rotation, and the counterweights 9 and 10 are at an angle of 45 ° to the vertical, and therefore their weights compensate each other (Fig. 2). Attached to the shaft of the working pulley 2 or to the plane of the pulley is a lever-arm 12 with the possibility of quick reinstallation of 90 ° on the pulley 2 (Fig. 1 and 3),

For example, when using the tetrahedral output of the pulley shaft 2 or a double-sided pawl with the fixation of the lever 12 in these positions.

The device works as follows.

At any abandoned position of the lever-handle 12, and the entire package of composable goods 8 is at the bottom, the working pulley 2 is in one of its two extreme fixed positions within the sag of the cable 4. This is determined by the fact that at any angular deviation from points of unstable equilibrium (point B in Fig. 2) of loads 9 and 10, the weight moment of one of loads 9 or 10 prevails over the other, which

leads to one of two possible equivalent positions of the pulley 2 - or the counterweight 9 occupies a horizontal position, or the counterweight 10 occupies a horizontal position, which creates a moment that raises the tension load 5 to the top position in the sleeve 6. At the same time, the positionally adjacent counterweight 10 or 9 is installed, on the contrary, in the upper position above the axis of the pulley 2, without creating any weight moment itself, i.e., either counterweight 9, or counterweight 10 without affecting its adjacent counterweight, statically and the tension load 5 in the upper support in the sleeve 6 (Fig. 1 and 3). During the transition period (Fig. 2), the counterweights 9 and 10 compensate for their weights, and therefore, the tension load 5 is located at the bottom of the sleeve 6, itself providing tension to the cable 4, but this is only in an unstable position of the device. In the dynamics of the device when moving the lever-handle 12 from one extreme position to another

 the inertia of the working pulley, balances and hand does not stop the movement of the device in any average position, in particular at the dead point of unstable balance of balances, but automatically translates it into the opposite initial state. Therefore, there is no free sagging cable. The cable is constantly tensioned by the difference in weight moments created by one of the counterweights 9 or 10 and the weight load 5. Therefore, the spontaneous jumping of the cable from the pulleys becomes impossible.

The device is designed to train both flexor muscles and flexors, depending on the design of the output organ, i.e. lever arms 12.

Q In FIG. Figures 1 and 3 illustrate the structure of a removable lever arm 12 for training the anterior arm muscle groups (biceps) and the posterior muscle groups (triceps).

When the lever arm 12 is installed at the bottom of the pulley 2 and the position of the pulley 2 with a horizontal load arrangement 9 (Fig. I), the front muscle groups (biceps) are subjected to training. At the same time, the athlete takes the handle 12 from below, 4) assestakes elbows approximately on the axis of the pulley 2, and turns the handle 12 along the arrow (Fig. 1), lifting a package of goods 8 through the cable 8. The length of the lever-handle 12 is equal to from hand to elbow of the athlete. Therefore, in the entire range of displacement of the hands by 180 °, corresponding to the similar rotation of the pawl 2 with the hand, the athlete experiences a constant load in the entire range of movement.

The proposed technical solution can be used in any universal simulator, where the front and rear muscle groups of the arms, torso, legs are alternately subjected to training. At the same time, it is provided with the convenience of using the simulator, and refining.
