UA77863C2 - Device for training muscles of legs - Google Patents

Abstract

The device for training the muscles of the legs comprises the turning frame capable of being fixed under selected angle. The frame contains the movable carriage and the leg rest. The axis of the turning frame locaters in its middle part. The frame is equipped with the seat and the telescopic tie-rod. The leg rest is mounted onto the carriage with the set of the weights.

Description

Description of the invention

The invention relates to sports and training equipment and can be used for training 2 physical athletes and athletes.

For training leg muscles, well-known various exercise bikes are usually used.

A special simulator is used for targeted training of extensor muscles of the legs. For example, with the use of an inclined board with adjustment of the angle of its inclination, on which a movable carriage is installed, and in the place of turning of the board, a stop is made for the feet of the athlete. The athlete sits on the carriage, leans against the lower stop and 70 performs extensor movements of both legs, moving along the board on the moving carriage. To increase the load, you can install a bar with added loads. The lower support for the legs is made with adjustment of the angle of its installation (1.

The prototype of the proposed invention is a device for training the muscles of the legs (2), placing a rotating board (frame) through a winding cable with the possibility of fixing the selected angle of its inclination, and in the turning point 72 of the board, a stop for the feet is made, and a movable carriage is installed on the board.

The reason preventing the ease of operation of the device and the increase in the convenience of training is that it is difficult to turn a heavy board with a carriage to the desired angle of inclination through a cable, attached to the free end of the board and wound on a drum with the subsequent autonomous fixation of the board with the help of a folding support, which is inconvenient in operation device. In addition, it is inconvenient for an athlete to climb onto an inclined carriage, especially if the carriage is previously loaded with a barbell with an inconvenient placement.

The proposed invention is based on the task of facilitating the operation of the device and increasing the convenience of training.

The task is solved by the fact that the bench for training the muscles of the legs accommodates a rotating frame with the possibility of fixing the selected angle of its inclination, on which a movable carriage is installed, as well as a rotating stop (U for the legs, the axis of rotation of the frame is located in its middle part, on one a chair is installed at the end of the frame, and the other end of the frame is connected to a rotating telescopic rod, while the rotating foot rest is placed on the carriage, on which the block of added loads is also mounted.

In fig. schematically shows the device. The device accommodates bases 1 and racks 2, with the axis of rotation from the frame to d; at the same time, the axis of rotation is placed in the middle part of the frame 4. At one end of the frame there is a chair and a counterweight 6. The other end of the frame is connected to a swinging telescopic rod 7 between the frame 4 and the base 1. A movable carriage 8 is installed on the frame 4, on which there is a swivel foot rest 9 with the possibility of adjusting the angle of the position with the help of an additional telescopic rod 10. On the carriage 8 racks 11 are also mounted, on which a block of bulk loads 12 is installed, either stationary or with the possibility of placing a removable standard rod. On the frame 4, there are also two standard folding latches - limiters 13 with handles 14, serving to limit the lower position of the carriage 8.

The position angle of the frame 4 is set by turning it around the Z axis and fixed with a pin on the telescopic rod 7.

Thanks to the selection of counterweight 6, turning the frame is easy and convenient. The angle of the position of the footrest 9 is adjusted with the help of an additional telescopic rod 10. 50 The athlete sits in the chair 5, rests both feet on the footrest 9, moves the latches 13 with the handles 14 to the sides and performs leg extension movements. At the end of the training, the retainers 13 are returned to the original

I" positions that separate the lower position of the carriage 4.

To train the muscles of the lower legs, set the required angle of the leg support 9 with the help of the telescopic rod 10. At the same time, the carriage 4 is also shifted.

The device has the following advantages over the prototype. Ease of operation of the device due to the fact that the axis of rotation of the frame is installed in its middle part and the moment of weight of the frame is balanced by a counterweight, therefore, the rotation of a heavy frame with a block of added loads is easy and convenient. Easy and convenient fixation of the lower position of the carriage in the initial state of the device is ensured. The convenience of training has been increased, as the athlete simply sits in a chair from the lower end of the frame, rests his feet on it and starts training.

Gee! 20 The device allows you to train not only the extensor muscles of the legs, but also separately or together to train the muscles of the lower leg in a similar way (|Z. c» In the sports club "Monolit" a device was made (see photo) and is used during training.
