Abstract

The utility model relates to training devices for the development and strengthening of muscles or joints with exercises to overcome the opposing effort, and can also be used in therapeutic restorative physical education. The proposed utility model solves the problem of increasing the number of expander functions by creating a simple, universal, small-sized, safe and affordable device. The expander contains handles' with through holes and a connecting element located between them. The handles are made in the form of rods with through step holes for fixing the connecting element. The connecting element is made in the form of a flexible inextensible cord, the length of which does not allow touching the phalanges of the fingers when grasping the arms and performing exercises in different planes and at different angles.

Description

The utility model relates to training devices for the development and strengthening of muscles or joints with exercises to overcome the opposing effort, and can also be used in therapeutic restorative physical education.

Known simulator (AS No. 1602560, publ. 10/30/90), containing handles in the form of frames and a connecting element located between them, in the form of a cardan joint and has a cross connected to two earrings, located perpendicular to one another . Each earring has an axis pivotally connected to it by one of its ends, the other end of which has a spherical head. In this case, each frame has a through hole associated with a conical recess in the frame, and each axis is freely installed in these holes. The spherical axis heads are located in conical recesses on the frame.

The disadvantages of the known simulator include insufficient efficiency, due to the limited range of exercises, the complexity of the design, significant dimensions. The presence of a rigid connecting element of the handle frames creates difficulties in the development of the simulator, and prevents more effective exercise. The complexity of the design creates an increased danger of performing the exercise. In the connecting element of the handle frames, made in the form of a cardan joint, for example, long hair may become tangled,

The proposed utility model solves the problem of increasing the number of expander functions by creating a simple, universal, small-sized, safe and affordable device.

To achieve the technical result, the expander contains handles with through holes and a connecting element located between them.

Distinctive features of the proposed expander from the known is the implementation of the handles in the form of rods with through step openings for securing the connecting element. The connecting element is made in the form of a flexible inextensible cord, the length of which does not allow touching the phalanges of the fingers when grasping the arms and performing exercises in different planes and at different angles.

The utility model is illustrated by drawings, where in Fig. 1 is a general view of an expander, in Fig. 2 is a section AA of Fig. 1, in Figs. 3 - 18 are diagrams of exercises performed using an expander.

The expander (figure 1, 2) contains the handles 1, a through step hole 2, the connecting element 3. The length of the connecting element 3 should not allow the phalanges of the fingers to touch when grasping the handles.

The proposed expander allows you to adjust the applied force, increase the amplitudes of the exercises and the number of functions;

allows you to perform exercises in pairs. The exercises are carried out in isometric, statodynamic mode and stretching - stretching, muscles. The principle of muscle loading is based on the self-resistance of one muscle group of another. The main effort created by the trained muscle is indicated by the arrow F, the support reaction created by the other hand is indicated by the arrow R. Exercises for loading the muscles of the chest, biceps, triceps, deltoid muscles are shown in Figs. 3-6. Load biceps, triceps, shoulder exercises shown in Fig.7, 8. Exercises in Fig.9, 10 load the triceps of the right hand, biceps of the left. Load the muscles of the back, deltoid muscles, trapezius muscles of the exercises shown in Fig.11, 12. The exercises shown in Fig.13-16 load the muscles of the shoulder girdle, back, arms. The exercises in Fig.17-18 load the muscle of the chest and shoulder girdle. The exercises shown in Figs. 7-18 are recommended with a change of hands.

The proposed expander allows you to simulate the movements of various sports, for example, gymnastics, weightlifting. The expander develops a subtle muscular feeling, which leads to good coordination of movements and the creation of more motor units in the body. Muscles are in tension throughout the entire exercise. This is most effective in terms of physiological efficiency. Using the proposed expander, exercises can be performed while standing, sitting, lying down (even for patients with bed rest), which expands the scope of its use.

Claims (1)

An expander containing handles with through holes and a connecting element located between them, characterized in that the handles are made in the form of rods with through step holes for fixing the connecting element in the form of a flexible inextensible cord, the length of which does not allow touching the phalanges of the fingers when grasping the handles and performing exercises in different planes and at different angles.
