Abstract

1. An apparatus for exercising leg muscles, comprising a member for supporting a torso, two foot plates adapted to change an angle between them and a loading means associated with said plates, characterized in that the member for supporting torso is provided with vertical guides adapted to change the height of the supporting member, the foot plates are pivotally connected to each other and have elements for fixing a knee joint, and the loading means is manufactured in the form of two levers pivotally connected to one another and to a corresponding foot plate, wherein at least one joint has a load regulation means, and the elements for fixing knee joints are pivotally mounted on the foot plates and spring-loaded to them.

Description

The device refers to the means of special physical training of athletes, as well as ballet dancers and can be used to develop mobility in the hip joints and muscle training, providing rotational movements in the hip joints.

A device is known for training the muscles of the arms, for fixing spinal injuries and developing the necessary posture of a person [1]. It contains telescopic vertical racks mounted on the base, interconnected by a crossbar. On the racks there is a spring-loaded backrest with tethered straps, and the base contains supports for placing the legs.

A disadvantage of the known device is the lack of specifying the direction of movement of the knees when performing squats. Their movement in the inverted position of the foot may deviate from the plane in which the foot and hip joint lie (the position required, for example, for classical ballet [2] or movements in artistic and artistic gymnastics).

A device for training swimmers [3] is known, which contains a support and a stand, on which is fixed a means for fixing the athlete's body, capable of moving along the stand, a platform for the legs, placed on the rods connected pivotally.

A disadvantage of this device is also the lack of specifying the direction of movement of the knees, which leads to the above result.

Closest to the claimed device is to stretch the muscles of the legs [4]. The device comprises a base, adjustable back support, pivotally connected platforms for placing the legs and a lever for controlling the cable-block system. One end of the cable is attached to the drum, while the others are connected to the platforms on which the rollers are fixed to ensure movement on the floor.

The disadvantage of this device is the unfinished back of the athlete relative to the support, allowing you to deflect the torso left and right, as well as the lack of a task to direct the knee joints when placing the feet on the platforms and performing squats of the Plié type.

The objective of the invention is to create a device for training the muscles of the legs, which would increase the efficiency of training by fixing the position of the body relative to the movable support and forcing the direction of movement of the knee joints.

The task is solved by the inventive device for training the muscles of the legs, containing support for the back, two platforms for legs, installed with the possibility of changing the angle between them, and a means of loading associated with the platforms for legs, due to the fact that the support for the back has vertical guides, made with the ability to change the height of the support, foot pads are pivotally connected to one another and have elements for fixing the knee joints, and the loading means is made in the form of two levers pivotally connected one with the other and with the corresponding platforms for the legs, while at least one hinge has a means of regulating the load, and the elements for fixing the knee joints are hinged on the platforms for the legs and are spring-loaded to them.

Thus, the task is achieved by introducing into the device two guides of the movement of the back support, two guides of the movement of the knees, a load-fixing device consisting of two levers pivotally connected to platforms for placing the feet and between themselves, and at least one hinge is equipped with a device for regulating load. The combination of these distinctive features unexpectedly for specialists in this field of technology provides a significant increase in the effectiveness of training the muscles of the legs.

To achieve an even higher effect, the device can be equipped with a drive, causing fluctuations in the angle between the platforms for placing the feet, which allows for additional training in the mode of biomechanical stimulation.

The device consists of a base, a support for the back, arranged to move along two guides, equipped with means for fixing on the body of the trainee, two platforms for placing the feet pivotally interconnected, two guides for the knees connected pivotally to the platforms for placing the feet the latter are equipped with rollers, and the guides for the knees - with elastic elements of the load-fixing device, consisting of two levers, pivotally connected to platforms for accommodating the station n, and with each other, wherein at least one hinge is provided with a device for adjusting the swing force can be fully fixing the angle between the platforms.

As already mentioned above, the device can be equipped with a drive that causes a fluctuation of the angle between the platforms for placing the feet (in particular, these can be point A oscillations set by the drive).

The inventive device will be described in more detail below using the example of one of the possible, but non-limiting preferred examples of implementation with reference to the positions of the drawing, which shows a general view of this preferred example of implementation.

The drawing shows a support 1 for the back, guides 2 movements of the support 1 for the back, guides 3 for the knees, elastic elements 4, platforms 5 for accommodating the feet, swivels 6, levers 7 of the load-fixing device and rollers 8.

The device works as follows.

1. Exercising set on the platforms 5 to accommodate the foot, spread the platform with the feet to the desired angle, then the angle is fixed with the help of the levers 7 load-fixing devices. Then the body of the trainee is fixed relative to the support 1 for the back. After this, the knees rest against the guides 3 for the knees. Then the practitioner performs squats of the Plié type, and the plane of motion of the knees is rigidly set by the guides 3 for the knees.

2. Trainees are installed in the same manner as described above, and the fixing device with levers 7 is used to create a load when diluting the stops to the sides along with the platforms 5 for placing the feet. Thus, the muscles are trained to provide vyvorotnost in the hip joints.

3. The practitioner is installed in the same way as above, the fixture with the levers 7 adjusts the device to the minimum load, then, acting on point A (see drawing), set the angle between the platforms 5 to accommodate the stop, and then act on point A via periodic oscillations while doing squats. It uses an additional effect caused by biomechanical stimulation of muscle activity (oscillation frequency of about 20 Hz).
