Description

The invention relates to a device for gymnastic exercises, namely a simulator, designed to train mainly the front surface of the thigh, namely the quadriceps.

Known multifunctional simulator, adopted as a prototype, including a base with vertical uprights, handles for the wrist grip, a device for the feet and seat (see the description of the patent of the Russian Federation No. 22259221, IPC AV 21/062 from 12/18/2003).

The design of the known simulator is difficult to operate for trainees with different anthropometry, since the lever gears are mounted on the frame and have a well-defined trajectory. In addition, the load is transferred from the load to the trainee through two or more blocks, while the blocks, often floating in the form of a chain block, which weakens the mechanical part of the structure and leads to frequent breakdowns, namely, the replacement of the cable.

In addition, high-quality muscle training on a well-known simulator requires a lot of weight, so the simulator is not suitable for people with reduced functional capabilities.

Another disadvantage of the known simulator is that the load on the muscles remains constant, as it is transmitted through a system of blocks, independent of the trajectory of the working limbs.

The technical task of the proposed device is to provide the trainee with various anthropometric characteristics and a different level of training, by increasing the safety during operation of the simulator and ensuring effective, regulated operation of the quadriceps.

The specified technical result is achieved by the fact that the simulator includes a base with vertical uprights, handles for the wrist grip and a device for feet and seats, while the base is made in the form of a rectangular frame, the vertical uprights are L-shaped and fixed with the possibility of limited rotation and fixation on the opposite the sides of the base, in the middle part of it, the upper ends of the L-shaped racks are equipped with slats fixed with the possibility of limited rotation and fixation in a vertical plane, on At one end of the planks, rods are fixed for hanging the counterweight, at the other end there is a weight load, and in the middle part there is an emphasis for the legs, fixed with the ability to move and fix along the L-shaped racks, the foot device is made in the form of rigidly fixed at the base of the L-shaped racks of the platform with an emphasis for feet, which is fixed with the ability to move and fix on the platform, handles for the wrist grip are fixed with the possibility of free rotation on the rods for hanging the load of weights, and the seat is made in the form platforms fixed on the strips from the side of the hand grip handles, and fixed with the possibility of rotation and fixation to the required angle in the vertical plane. The seat is made with a close fitting. The support for the legs is made with a soft close-fitting.

The seat is made with a close fitting. The support for the legs is made with a soft close-fitting.

The presence of an emphasis on feet on the device for feet and an emphasis on the legs allows you to work out the quadriceps in an anatomically safe position, excluding the displacement of the feet forward, and the presence of a seat - to protect the work of the knee joints, setting the working amplitude safe for the knees.

The presence of rods for hanging the counterweight facilitates the lifting of the trainee up, and the load of weights provides load regulation during work.

In the proposed simulator, even with full lifting upwards - in a standing position, part of the body weight always remains behind the pivot point in the knee joint, which maintains constant tension in the quadriceps, making them more efficient to work out, especially when using L-shaped racks located in a vertically rotated plane position.

The proposed device has a compact, simple and safe design, convenient to use for students with various anthropometric characteristics, both beginners and professional athletes.

The simulator is presented in the drawings, where: in Fig.1 shows a General view of the device, option 1; figure 2 - also, option 2; figure 3 - the first working position (option 1); figure 4 - working position with weights (option 1); figure 5 - working position with an inclined arrangement of L-shaped racks (option 1); figure 6 - working position without weight (option 2); Fig.7 - working position with weights (option 2).

The simulator contains a base 1, made, for example, in the form of a rectangular frame from a metal profile and two L-shaped vertical posts 2, mounted on the axles 3 with the possibility of limited rotation and fixation on opposite sides of the base 1 in the middle part of its part, for example, by means of a latch 4, installed in the holes of the brackets 5, rigidly fixed on opposite sides of the base 1.

The upper ends of the L-shaped racks 2 are equipped with straps 6, fixed with the possibility of free rotation-swing on the axles 7. The latches 8, installed in the holes (not shown) of the brackets 9, mounted on the L-shaped racks 2, ensure the fixation of the strips 6 when they are rotated in a vertical plane to the angle necessary for work.

In the middle part of the L-shaped racks 2 there is an emphasis for the legs 10 with a soft close-fitting, fixed with the possibility of movement along the L-shaped racks 2 and fixed by means of the clamps 11 at the required height. At the base of the L-shaped racks 2, a foot device is rigidly fixed, made in the form of a platform 12 with an emphasis 13 for the feet. The stop 13 for feet is fixed with the possibility of movement along the platform 12 and fixation in the desired stop position by means of the latch 14.

At one end of the slats 6, rods 15 are fixed for hanging a weight load, and at the other end, rods 16 for hanging a counterweight.

Handles 17 for wrist grip are fixed with the possibility of free rotation on the rods 15 located on the opposite side of the device for the feet.

The simulator contains a seat made (option 1) in the form of a platform 18 with a soft-fitting tightened between the straps 6 on the side of the hand grips 17 with the possibility of rotation and fixation in a vertical plane by means of a screw (not shown) and relative to the straps 6 - by means of a latch 19 .

The seat (option 2) can be made in the form of a platform 20, mounted on the base 1 from the side of the hand grips 17 by means of the rack 21 with the possibility of movement in the vertical plane and fixed on the rack 21 at the required height by means of the latch 22.

The simulator (option 1) is used as follows.

First, the trainee adjusts according to its anthropometric characteristics the position of the abutment 13 on the platform 12, then the height of the abutment 10 for the legs and the position of the seat 18. Then it determines the minimum angle of rotation of the strips 6 relative to the L-shaped racks 2, installing the clips 8 in the corresponding holes of the bracket 9 and the other side of the L-shaped rack 2, thereby determining the depth of lowering of the seat 18 when working on the simulator. Then hangs on the rods 16 counterweight and begins to work, dropping down and turning the strap 6 on the axes 7 relative to the L-shaped vertical posts 2 at a certain angle, fixed by the latches 8 (Fig.3).

The working position (figure 3) is intended primarily for beginners.

The reverse movement when lifting to its original position facilitates the counterweight mounted on the rods 16.

The latches 8 fix the seat 18 with the seated trainee usually slightly below the horizontal at the moment when he cannot climb up using the force of his legs, thus insuring the knee joints from excessive overload with low gray hair.

The leverage of the strips 6 is constructed in such a way that the higher the thigh of the trainee rises, developing greater strength, which is due to both the degree of muscle contraction and the angle of work in the joint, the lower the shoulder of the strips 6 with a counterweight, and therefore, the less effort to lift the trainee. This ensures correct movement facilitation:

- the greatest help at the lower point of movement is more necessary, since the muscles are stretched and the knee is very bent;

- minimal - in the upper part of the movement, when the thigh muscles are contracted more strongly and their strength is greater than at the start from the bottom.

The load accentuates the quadriceps. Only when the body is tilted forward, the buttocks and biceps of the hips can be included in the work.

The simulator (option 1) can be used with weights (Fig. 4), for which they remove the counterweight from the rods 16 and put the load of weights on the rods 15. For experienced athletes, you can set the load on the quadriceps in a limited amplitude, setting the required angle of rotation of the straps 6 with the load weights and fixing it with the help of clamps 8, while the trainee begins to work in the selected amplitude of extension of the knees.

The simulator (option 1) can be used with weights (figure 5), when the work can be enhanced by changing the angle of inclination of the L-shaped racks 2 in the vertical plane. In this case, most of the trainee’s body weight will be behind the point of rotation in the knee joint, which will leave the tension in the quadriceps more than with the usual performance, even at the top point in the standing position.

The simulator (option 2) is used as follows.

At first, the trainee adjusts, according to its anthropometric characteristics, the position of the stop 13 for the length of his feet, the height of the stop 10 for the legs and the position of the seat 20 on the rack 21. Then he hangs the counterweight on the rods 16 and, holding the rotating arms 17, starts to work, dropping down and turning the slats 6 on the 7 axes relative to the L-shaped vertical posts 2. This work position is intended primarily for beginners.

The role of the transfer of force from the counterweight to the trainee will be performed not by the seat, but by the hand grips 17 located on the rods 15, both for beginners and athletes.

The simulator (option 2) can be used with weights (Fig. 7), while when lifting into a vertical position, a trained, mainly experienced athlete, raises the ends of the slats 6 with a load of weights. In this case, the seat 21, mounted on the rack 22 of the base 1 at the required height, insures the trainee from excessive lowering.

The proposed simulator can also be used with the strips 6 removed from the L-shaped racks 2.
