Description

The utility model relates to sports, namely, simulators for athletic gymnastics and powerlifting.

A device for training muscles is known (Patent No. 2217201 RU). The device comprises a rod, fixing means, racks with rod holders, an additional rack on which a counterweight cargo is mounted, a movable platform located under the counterweight and connected to the rod. In this case, the fixing means is made in the form of an additionally mounted, rocker arm strut, the upper end of which contains a protrusion-tooth that fits into the annular groove on the lower surface of the load, fixing it on the strut, and the lower end of which is spring-loaded.

A disadvantage of the known device is the injury of the shoulder and elbow joints when working with maximum weights, as well as muscle strain. This is due to the fact that the barbell is a rigid rod, which, during the exercise by the athlete, moves only along a certain trajectory and does not allow the joints to adjust to the work being performed, which in turn leads to injuries.

Known simulator, taken by us as a prototype. Body-Solid PRO CLUB SSMG-350 power simulator Smith Machine. Item: SSMG-350. (http://www.bodysolid.ru/picture.php?product_id=248). Smith machine contains vertical support racks connected by a crossbar and forming a frame. To the supporting racks and parallel to them are attached tubular racks that act as guides for rod holders that are connected to the bar. The bar of the bar, connected to the bar holders, through the carriage containing bearings, allowing the bar to be rotated around its axis.

Smith's machine is a multifunctional simulator that allows you to perform various exercises aimed at correcting the physique of the student (squats, bench press, bench press in front of the chest, from behind the head, etc.).

A disadvantage of the known device is the injury of the shoulder and elbow joints when working with maximum weights, as well as muscle strain. This is due to the fact that the barbell is a rigid rod, which, during the exercise by the athlete, moves only along a certain trajectory and does not allow the joints to adjust to the work being performed, which in turn leads to injuries.

The objective of the proposed utility model is the elimination of injuries due to training in the simulator, which, in the process of performing exercises, is able to ensure uniform development of the athlete’s muscles, increase their strength, as well as strengthen the shoulder, elbow and joints of the hands, and most importantly, the joint bags and ligament apparatus surrounding these joints. In the process of doing the exercise, muscle stabilizers are involved.

The proposed problem is solved by a device for training muscles, containing a frame formed of two load-bearing vertical posts connected by crossbars in the upper and lower parts, and installed on the basis of additional stiffeners containing platforms for storing weights. Tubular racks are attached to the supporting racks and parallel to them, acting as guides for rod holders, which are connected to the rod by means of carriages containing axial rotation bearings through which the bar neck passes and makes it possible to turn the bar around its axis. The barbell of the rod has on its rod the means for fixing the bar holders, made in the form of hooks of hooks, for technical pins located parallel to the inner sides of the supporting racks and allowing to stop the bar of the rod at the required height. Under the rod holders on the guide tubular racks are installed with the possibility of vertical movement and fixation at the required height for the technical pins, rod catchers, performing the role of stops. The bar of the rod contains a metal rod, consisting of three parts connected by two grip blocks installed between them for fixing the hands with a weld. The handle block comprises a sliding bearing comprising an inner and an outer ring mating with each other on a spherical surface. In the inner ring, a horizontal bar is fixed for grasping with a hand. Around each bearing, a removable protective device consisting of two hemispheres is mounted, fixed on the rod. Coaxial round holes are made in the upper part of the hemispheres for the passage of the hands, and on the inner surface of the hemispheres, a protrusion is located around the entire perimeter, restricting the movement of the inner ring of the bearing relative to the outer one within 20-30 °. The upper parts of the hemispheres for the holes are made flat. The simulator may further comprise a reclining bench.

The technical result is the creation of the necessary individual conditions (to provide a "physiological" working plane in the shoulder, elbow and wrist joints) for the athlete's joints. Creating the necessary position, providing the necessary supination and pronation in the elbow and shoulder joints during the exercise, by sliding the inner ring of the bearing, relative to the outer, thereby allowing the joints to perform safe work in the joint bags at any stage of the exercise. This factor favorably affects the strengthening of joints, joint bags, ligaments of the joints surrounding and supporting the joint bag. A fixed angle of 20-30 ° is achieved due to the axial rotation of the inner ring, relative to the outer, will provide a comfortable position for the athlete’s hand, excluding it by the gym.

The device for training the muscles (Fig. 1) and (Fig. 2) contains a frame formed by struts 1 and connected by means of screw connections with crossbars 2, reinforced with additional struts 3, which give rigidity and stability to the structure, containing platforms 4 for storing weights, which bar 8 of the bar is loaded. Tubular racks 5 are fixed in the frame, which act as guides for the bar holders 6. The bar holders 6 are represented by linear motion supports that exclude any distortion and provide soft gliding. The rod holders 6 contain a carriage 7, which connects it to the bar 8 of the rod by means of bearings 9, providing rotation of the mane 8 of the rod, necessary for the operation of fixing means made in the form of a rod 8 mounted on the bar, two hooks 10 fixed on technical pins 11 They are located parallel and at the same level relative to each other on the inner side of the supporting racks 1 at different heights. Thus, they can change the height for the optimal position of the loaded bar 8 of the bar at the beginning and end of the exercise, fixing the bar 8 of the bar at the required height. The lower end of the hook-hook 10, is fixed on the neck 8 of the rod. The bar 8 of the rod contains a metal rod, consisting of three parts connected by two handle blocks 12 mounted between them, intended for fixing the hands. The handle blocks 12 are slide bearings containing an inner ring 14 and an outer ring 13, mating with each other on a spherical surface. In the inner ring 14, by means of the weld seam 15, a crossbar 16 is fixed for grasping with a hand. Around each bearing, a removable protective device 17 consisting of two hemispheres is mounted, fixed on the rod. In the upper part of the hemispheres, coaxial holes 18 are made for passing the hand, and on the inner surface of the hemispheres, a protrusion 19 is located around the entire perimeter, restricting the movement of the inner ring of the bearing 14 relative to the outer ring 13 within 20-30 °. The upper parts of the hemispheres for the holes are made flat. The parts of the bar of the bar 8 of the bar, are connected to the outer 13 bearing rings mounted between them, by a weld seam 15. The end parts 20 of the bar of the bar 8 of the bar contain platforms for installing and fixing discs. Below the rod holders 6 are adjustable catchers 21 of the neck 8 of the rod, consisting of a rocker 22, fixed on the inside of the rack 1 by the technological pins 11. The other part is represented by a tube 23, the upper part of which contains a rubber ring 24. The catcher 21 is capable of moving along tubular racks 5 and limit the movement of the rod holders 6, acting as a stop, adjusting the location of the bar 8 of the rod, thereby ensuring safety.

A device for training muscles, is used as follows. Consider the example exercise: "Bench press lying."

On the site for the installation of cargo disks 20, set the required number of disks. The athlete sets the catchers 21 of the bar 8 of the barbell at the required height, which is necessary to ensure the safety of the exercise and will prevent the student from being pressed down by the bar 8. The athlete assumes the initial horizontal position on the bench under bar 8 of the bar. It fixes the hands on the crossbar 16 of the inner ring 14 of the bearing of the grip unit 12, through the holes in the hemispheres 18.

The athlete raises the bar and rotates the bar 8 of the bar, removing hooks-hooks 10 with technological pins 11. When lifting, the inner ring 14 of the bearing assumes the necessary position, thereby ensuring a convenient and safe arrangement of the athlete's hands, which can prevent the gym. The limiter of the trajectory of movement of the inner ring 14 of the bearing is a technological protrusion 19, made around the inner perimeter of the hemispheres 17. The vertical movement of the bar 8 of the bar, determine the bar holders 6 and the guide racks 5. 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 ring 14, relative to the outer ring of the bearing 13 and around the perimeter of the restrictive protrusion 19 This, in turn, will provide the necessary "physiological" working plane in the elbow, shoulder and wrist joints of the practitioner. This work plane requires constant adjustment, to exclude injuries and unload the listed joints, at any stage of the exercise. Constant adjustment of the working plane, through the grip blocks 12, involves stabilizers in the muscles, allowing training to maximize the athlete's power potential.
