Description

The utility model relates to stationary sports simulators designed to train the human body, in particular the latissimus dorsi, round muscles of the back, and biceps of the arms.

A well-known simulator, taken by us as a prototype, is a professional power simulator for sports clubs and gyms Body Solid PRO CLUB SRMG-1700 "Thrust to the chest with emphasis" (http://www.bodysolid.ru/products.php?tab=product&product_id= 241).

The CLUB SRMG-1700 power simulator "Thrust to a chest with an emphasis" is presented by a design with a wide base. The workplace contains a height-adjustable seat and a length-adjustable chest rest mounted on racks, which in turn are rigidly fixed to the base and interconnected by a crossbar. On the basis of the simulator with its lower end with the possibility of rotation by means of an axial connection containing carriages and bearings, a movable lever is fixed, in the upper part of which there are handles for interlocking, connected by a movable bracket. On the base are also two platforms for supporting the legs. Load transfer occurs through the lever system using rotational mechanisms containing bearings and a metal cable connecting the lever with the assembly, which is a burden during the exercise, consisting of metal plates stacked in a stack.

The disadvantages of this simulator are the large size and heavy weight of the node that provides resistance, the complexity of its design. Grips for grasping with hands, fixed on the bracket, allow you to perform the exercise with three types of grip: direct, reverse and neutral grip. Structurally fixed types, in turn, do not allow muscles to be worked out at different angles during training. To work out the muscles, it is necessary to change the types of grip, and this is not possible without changing the initial position of fixation of the hands on the arms. The operation of the lever with fixed types of grip cannot guarantee complete safety when performing exercises with maximum weights. This is due to the fact that the lever is a rigid structure, the movement of which during the exercise by the athlete is possible only along a certain predetermined path, and the fixed handles do not allow the joints to fully adapt to the work being performed. This, in turn, can lead to trauma to the shoulder and elbow joints, as well as muscle strain or tear when working with maximum weights.

The tasks to which the claimed utility model is directed are to expand the arsenal of devices aimed at training and developing the muscles of the back and arms; creation of a stationary sports simulator of a simplified design; expanding the range of exercises on the simulator; reduced likelihood of injury; ensuring uniform development of the athlete’s muscles, increasing their strength; strengthening the ligamentous apparatus surrounding the joints involved in the work.

The tasks are solved by a sports simulator for the development of the muscles of the back and arms, consisting of the athlete’s workplace, lever and T-shaped base. The workplace contains a height-adjustable seat and a length-adjustable chest rest, which are mounted on racks that are rigidly fixed to the base. On the basis of the simulator, two platforms for supporting the legs are fixed. The lever for traction with the possibility of rotation is made in the form of a fork fixed on the base with its lower end by means of an axial connection containing carriages and bearings. The upper ends are connected by a movable bracket, to which are attached handle blocks, consisting of nodes for fixing the hands and a protective removable device. The node for fixing the hands contains a sliding bearing, consisting of an inner and an outer ring mating with each other on a spherical surface and a crossbar for grasping with a hand fixed in the inner ring. The protective removable device consists of two hemispheres mounted on a metal rod for attaching the blocks to the bracket around the nodes for fixing the hands. Coaxial holes are made in the upper part of the hemispheres for passing the hand, and on the inner surface of the hemispheres there is a protrusion around the entire perimeter, restricting the movement of the inner ring of the sliding bearing relative to the outer one within 20-30 °. On the lever below the bracket, restrictive supports are installed. On the base under the lever there is an emphasis restricting its movement. To ensure the load in the training process, a platform for setting weights is located on the lever. The racks on which the athlete’s workstation is located can be installed at an angle to the support and interconnected. The crossbar located in the inner ring of the bearing and the metal rod connected to the outer ring of the bearing can be fixed with a weld. Handle blocks are attached to the bracket by means of a threaded connection or a weld. The upper parts of the hemispheres for the holes are made flat, and the holes themselves are made round. On racks under a seat and a chest emphasis spring clips are established for regulation of height of a seat and length of a emphasis of a breast. The weighting pad may include a spring clip to prevent the weights from slipping.

When solving this problem, a technical result is achieved, consisting in simplifying the design of the simulator, reducing its weight and dimensions, reducing the metal consumption of the simulator. The implementation of the grip unit allows you to expand the range of exercises on the simulator by changing the position of the hands without changing the position of the initial fixation of the hands on the crossbar of the inner ring of the bearing. At any stage of the exercise, the handle blocks of the simulator create the necessary individual conditions for the joints of the hands of each individual athlete. Provide a comfortable position of the hands by changing the position of the crossbar of the inner ring to the outer ring of the bearing within 20-30 °. Axial rotation of the inner ring of the bearing relative to the outer ring allows traction by any type of grip. Creates conditions that allow you to work out the muscles involved in the exercise from different angles. Increases the number of muscles involved in the exercise. Reduces the likelihood of injury due to training on the simulator, ensuring uniform development of the athlete's muscles and increase their strength. Also, it allows the joints to perform safe work in the joint bags at any stage of the exercise, preventing dislocations (the grip block provides the necessary supination and pronation in the elbow and shoulder joints during the exercise, supports the “physiological” work plane in the shoulder and elbow joints). This factor helps strengthen the shoulder and elbow joints, as well as the articular bags and ligamentous apparatus surrounding these joints while working with maximum weights.

A sports simulator for the development of muscles of the back and arms (Fig. 1) and (Fig. 2) consists of the athlete’s workplace, comprising a height-adjustable seat 1 and a height-adjustable chest rest 2, which are mounted on racks 3 and 4, respectively, rigidly fixed on the base 5. On the basis of the 5 simulator two platforms 6 for supporting the legs are fixed. The lever 7 for traction of arms with the possibility of rotation is made in the form of a fork fixed to the base 5 with its lower end by means of an axial connection 8 containing carriages and bearings 9. The upper ends of the lever 7 are connected by a movable bracket 10 to which the handle blocks 11 are attached (FIG. 3), consisting of nodes for fixing hands and protective removable devices. The node for fixing the hands contains a sliding bearing, consisting of an inner 12 and an outer 13 rings, mating with each other on a spherical surface and a bar 14 for gripping with a hand fixed in the inner 12 ring. The protective removable device consists of two hemispheres 15 mounted on a metal rod 16 for attaching the blocks 11 to the bracket 10 around the nodes for fixing the hands. In the upper part of the hemispheres 15, coaxial holes 17 are made for passing the hand, and on the inner surface of the hemispheres 15 there is a protrusion 18 around the entire perimeter, restricting the movement of the inner 12 of the sliding bearing ring relative to the outer 13 of the ring within 20-30 °. Limit supports 19 are installed on the lever 7 below the bracket 10. On the base 5, under the lever 7 there is an emphasis 20 restricting the movement of the lever 7. To provide the load in the training process, the lever 21 is equipped with a platform 21 for setting weights.

A sports simulator for developing the muscles of the back and arms is used as follows:

Before performing the exercise on the site 21 for weights loaded with the required number of disks. The athlete sets the required seat height 1, which ensures a comfortable position of the body during the exercise, and sets the optimal length of the chest rest 2, corresponding to the length of his arms. It rests with feet in the platform 6 for leg support. It fixes the hands on the bar 14 of the inner ring 12 of the bearing of the grip unit 11 through the holes 17 in the hemispheres 15. The exercise starts with the contact of the bracket 10 with the limit supports 19. Applying physical effort to the bar 14 of the grip unit 11, the athlete takes out of contact with the limit stop 20 lever 7 and performs the pull of the lever 7 on itself. After completing the traction, the lever 7 returns in the opposite direction until the arms are straightened in the elbow joints. When performing traction, the inner 12 ring of the bearing assumes the necessary position, thereby providing a convenient and safe arrangement of the athlete's hands, which can prevent the hall. The restriction of the trajectory of movement of the inner 12 ring of the bearing is a technological protrusion 18, made along the entire inner perimeter of the hemispheres 15. In the process, the position of the hands can be changed, while maintaining the safety of the exercise, providing the necessary supination and pronation in the joints due to the slip of the inner 12 of the ring relative to the outer 13 bearing rings and around the entire perimeter of the restrictive protrusion 18. This, in turn, will provide the necessary "physiological" working plane in oktevyh, shoulder and wrist joints of the hands of the athlete. This work plane requires constant adjustment to exclude injuries and unload the listed joints at any stage of the exercise. After completing the exercise, the lever 7 returns to its original position, defined by the limit stop 20.

The inventive sports simulator is industrially applicable, because it is convenient in operation, helps to reduce the metal structure and reduce the cost of the product.
