Description

The invention relates to sport and serves to develop the strength of the muscles of the legs of athletes, mainly t-athletes, which are contraindicated for squats with a barbell on their shoulders because of first person, it is pain in the lumbar spine.

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

FIG. 1 shows the device, obsh, iy view; in fig. 2 shows section A-A in FIG. G; in fig. 3 shows a section BB in FIG. 2

The device for developing the strength of the muscles of the legs contains a supporting disk base 1 fixed in the foundation we are 2 under the floor 3 (platforms) of the gym. On the support base 1 there are fixed guide pins 4 on which the cargo disks 5 are mounted. In the holes of the cargo disks 5 there is a tubular support 6, which has a hook with a welded pin 7. A loop 8 belt is attached to the pin 7, which is attached to the belt 9 athlete. The pipe is made in the form of glass.

In the bottom 10 (FIGS. 2 and 3). The pipe 6 is fixed to an axis 11, on which the sleeve 12 is rotatably mounted, equipped with a handle 13. Radially spring-loaded rods 14 are fixed to the pipe walls. Grooves 15 are made on the inner surface of the cargo disks 5 to engage the rods 14 by pressing the cam sleeve 12 thereon.

On the inner surface of one of the cargo disks 5, for example, the upper ones, there are fingers 16, which enter the grooves 17 of the pipe 6. The grooves 17 are guides for the fingers 16.

The ends of the studs 4 are attached to the plate 18, which is made removable and has a hatch 19, closed by a removable lid 20. The hatch 19 has the ability to enter the pipe b with the pin 7, belts 8 and 9, the cam sleeve 12 and the handle 13.

At the end of the pipe 6 a scale of 21 weights is applied, and on the handle 13 a weight pointer 22 is applied. Rubber pads 23 are installed between the cargo disks 5 to reduce noise.

The device is used as follows.

The hatch 19 is opened. Turning the handle 13 and combining the arrow 22 on the handle with the Scale 21 at the end of the pipe 6 sets the required amount of weights. In this case (Fig. 2), with their protrusions 24 cams of cargo bushing 12 presses against the rods 14 located opposite the grooves 15 of one of the cargo disks 5. These rods enter the grooves 15.

sleeve 12 is fixed by the occurrence of adjacent rods 14 in recesses 25.

Then the athlete fastens the loopback belt 8 fixed to the tube 7 of the tube 6 to his sleek belt 9 and makes squats. When lifting, the pipe 6 together with the fixed disk 5, as well as with the disks 5 located above the fixed one, moves upward through the studs 4. At the same time the cargo disks 5 located below the fixed disk 5 remain in place on the supporting disk 1 (Fig. 1 ).

when lowered, the tube 6 with the discs 5 moves downwards. The reduction of the schum contributes to the fit of the lower lifted disk 5 on the rubber gasket 23 of the upper lifted disk 5 (or the supporting disk 1). To install another lift, the weight of the handle 13 is again applied. At the same time, the tube 6 is secured against rotation

0 is carried out with the pin 16 of the upper loading disc. The finger 16 is located in the groove 17 of the pipe 6.

After the end of the training session, the belt 9 is removed from the belt 8, the hatch 19 is closed by the cover 20.

5 The device can also be used to develop the strength of the muscles of the hands, forearm, back, chest, etc. In this case, the athlete hands or not the belt 8 directly, lifting the pipe 6 with a fixed load, or lying flat, having fixed the belt 8 on the slit or on the back, it is pressed from the floor 3.

Maintenance is provided by removing the plate 18 from the chucks 4 and lifting the plate 18 upwards.

Thus, the use of the proposed device allows not only to train athletes who, when squatting with shtanga, appear pain in the lumbar spine, but also significantly protect the training process itself, since all the moving parts with a large weight are located in closed place. In addition, there is no need for the athlete to directly attach the load disks, it is enough just to turn the handle 13 to the desired scale mark 21.

5 The use of the plate 18 with the closing lid 20, the hatch 19 allows the area of the hall for other sports to be free. All this contributes to the convenience of using the device. Performing on the device other strength exercises

 increases the versatility of its use. The introduction of the device will contribute to the rapid growth of t-class athletes and other athletes.
