Disclosure of the essence of the invention.

The technical result, to which the claimed solution is aimed, is to combine in one device the functional capabilities of various simulators in various combinations and to create a compact universal sports simulator for the home, occupying a minimum area and volume in an idle state, providing a comprehensive training of adolescents and adults in conditions of limited area of the room with the ability to change the configuration of the simulator by one person.

Modularity of construction. Modification of the simulator execution options is made by replacing individual structural elements and installing hinged elements.

Method of fixing the device. The load-bearing stand of the simulator is a rigid volumetric structure fixed in spacer between two parallel surfaces, which allows, with a small area of the lower support surface, to provide a stable balance under load.

The versatility of the sports trainer. The rack and attachments allow you to perform a wide variety of exercises with adjustable loads and coverage of various muscle groups of an athlete of various heights and weights. The device can be made in various combinations of attachments, giving the athlete the opportunity to choose the best option.

Embodiments of the invention will now be described by way of example with reference to the accompanying drawings.

The first version of the execution. The basis of the design (Fig. 1) for all variants is the bearing rack 1 (hereinafter referred to as the rack), which has a rigid collapsible volumetric structure with supports 2 on the lower horizontal support surface (floor of the room) and adjustable screw stops 3 on the upper horizontal support surface (ceiling of the room ). Such fastening of the rack ensures the stability of the structure under loading, excludes overturning, since the distance between the opposite diagonal points of support is greater than the shortest distance between the surfaces. In the first embodiment, the following elements are installed on the rack 1: horizontal bar 4 with the possibility of performing various grips, bars 5 with a friction on the attachment axis, backrest without a lock 6, lodgements for dumbbells 7, handrails 8, 9. You can additionally install a holder for a tablet or phone , holders - for water, towels, small things, removable sports equipment, etc. The friction clutch on the axis of the bars is designed to prevent their free fall. The horizontal bar, in addition to the main function, can be used to mount various devices, for example, the TRX type. Handrails and horizontal bar can be a fastener for resistance bands, elastic bands. The lower handrails can be used for exercise on the mat. For use in rooms of different heights, the rack can be manufactured in several heights. Within certain limits on the height of a particular room, the device is adjusted by screw stops during installation. The area of the lower support surface of 560 x 600 mm ² is several times smaller than that of the prototypes discussed above.

Second execution option. The design includes (Fig. 2) elements of the first version and a rack, in which the upper and lower transverse beams of the rack of the first version are replaced by beams 10, 11 of the second version with mounted blocks of the cable-block system. In the second embodiment, one weight block 12 is installed, a cable block system 13, two guides 14. The force at the cable outlet is equal to half the weight of the involved weight block stack. In addition to the first option, it is possible to perform exercises for biceps, triceps, abduction of the leg to the side, back, as well as others using the upper and lower traction.

The third variant of execution. The design includes (Fig. 3) the elements of the first version and the rack, in which the upper and lower transverse beams of the rack are replaced by a beam 15 with mounted parts of the cable assembly system and a beam 16 of the third version. In the third embodiment, two cantilever blocks 17, two weight blocks 18, two cables 19, four guides 20, two outboard pivoting levers 21 are installed, fixed on the rack (hereinafter referred to as levers). The weight of the load block can be different and can be determined by the customer. The force at the exit of the cable is equal to half the weight of the involved load stack. In addition to the first option, it is possible to perform all exercises of functional simulators.

The levers have three links and three axes of rotation - in order, if you count from the rack - vertical, horizontal and parallel to the axis of the second link. The cable, passing through the system of the lever blocks, does not move along the axis when the lever links are turned. The first link 22 can be rotated in the horizontal plane at an angle of 180 degrees. The second link 23 rotates in a vertical plane from a position vertically up to a position vertically down, the rotation of this link is slowed down by the clutch 24 to prevent free fall. The links are fixed by locks 25, 26 in the end or intermediate positions. The last, third link 27 can freely rotate 360 degrees. The levers are designed to bring the cable tip to a given point within the design range. The range is determined by the angles of rotation and the dimensions of the links, which can vary from project to project.

The levers provide a wide variety of applications. On this version of the simulator, you can work out every muscle and plane of motion. The design makes it wheelchair accessible and comfortable for all training levels. Independent adjustment of the output pivot arms, for example, with 13 vertical and 13 horizontal fixed positions in a 180 degree range, gives 169 fixed positions for each lever, and in the combination of the two arms practically does not limit the options for use. Two cable-block systems and two load stacks, for example, from 60 to 100 kg, provide a load from a minimum of 2.5 kg to a maximum of 30 to 50 kg with a step of 2.5 kg at the exit of each cable and the independence of the movement of the cables. The output of each cable, for example, from 2.35 m to 2.8 m, depends on the size of the load stack and provides training with a good range of motion in the dimensions of a typical apartment.

Fourth option. The design includes (Fig. 4, 5, 6, 7) a stand with elements in the first version, a folding sports bench 28 (hereinafter referred to as the bench), a footrest 35 with thrust rollers 36, bench accessories 29, 30. The stand has a backrest without a lock was replaced by a backrest with a lock of a bench 31.

The bench is hinged to the post at two points and can be folded into the dimensions of the supporting post. To fold, set the back of the bench 33 in the same plane with the seat 32, remove the seat clips 37, pull the seat handle up and in the direction of the rack, turning the seat around the axis of rotation and bringing the seat to a vertical position, until the lock is activated, and then lock the bench in two places. In the retracted state, the bench is fixed with a lock and in two places it is blocked with a pin lock to prevent unintentional disclosure. The first lock duplicates the lock, the second prevents the bench seat from rotating relative to the folded frame 38. To bring it into working condition, it is necessary to make sure that there are no obstacles to the movement of the support roller of the back of the bench 34. The roller of the back is designed to ensure the movement of the end of the back on the floor when folding and bringing the bench into the working position and does not bear any load during exercises. Remove locks and. while holding the seat handle, pull the bottom of the bench away from the upright, pivoting relative to the frame. When, after turning the bench seat by a certain angle, the lock opens, carefully lower the bench onto the supporting surface. Set in the desired position and fix the seat with the latches 43 and the back of the bench with the lock 44 in the desired position (Fig. 8). In the working position, the seat and back of the bench have the ability to rotate around the horizontal axes transverse to the bench and have several fixed positions.

The bench frame is hinged to the post, the seat is hinged to the frame, the bench back is hinged to the seat body. Constructive dimensions, angles of rotation of the seat and backrest, options for installing devices are selected taking into account ergonomic requirements, and ensure the use of the simulator by adolescents and adults.

The bench can be used for strength training using free weights or with other devices to increase the number and types of resistance exercises.

Out-of-service bench fixtures are stored in special nodes at the bottom of the rack. For use, they are inserted into the longitudinal beam of the seat and fixed in the position required for the exercise (Fig. 6, 7). The leg attachment is used when doing abdominal exercises. The design allows changing the outlet of the rod 39 to adjust for the growth of the athlete. The hyperextension device is used to train the muscles of the back, buttocks and the back of the legs. By changing the output of the rod 40, you can change the angle of inclination of the body during the exercise, the required position (angle of installation) of the support platform of the device is set by rotating the adjusting screw 41. Adjustment for the athlete's height (the distance from the center of the support platform of the device to the footrest) is made by turning the bench seat or in a small range by turning the device 180 degrees at the attachment point. The center of the tool support platform is offset from the stem axis by 50 mm, such a turn will displace the platform by 100 mm.

Fifth execution option. The design includes (Fig. 8, 9, 10) a rack with hinged elements in the third version, hinged elements of the fourth version - a footrest with thrust rollers and a folding gymnastic bench with devices 29, 30, as well as a bench device 42. the backrest without a lock was replaced with a backrest with a lock 31, a bench device 42 was installed on the backrest when it was not in operation - an additional back support. The method of its use is shown in FIG. 9. Compared with other variants, the number of exercises for the fifth variant of the exercise machine performance increases significantly due to the separate and joint use of the installed elements and devices. The device in the maximum configuration allows for the most versatile training, adapted for installation in a room, occupies a small area when not in use. Changing the configuration of the simulator - changing the position of the levers, folding and bringing the bench into working condition, adjusting the seat and back, changing the load on the cables, using devices - does not require much effort and can be done by one person.

As an example, the device in the fifth version has an area of the lower support surface of 560 * 600 mm ² , dimensions in the folded state - width 1150 mm, length 610 mm. Maximum dimensions in working condition - levers horizontally, angle of the first link 0 degrees (as in Fig. 8), seat in working position, backrest horizontally (as in Fig. 9), - width 2985 mm, length 2480 mm. For training on the simulator in the fifth version, you must have a free area of at least 3 * 2.5 m ² , when folded, the device occupies an area of more than 10 times less.

The simulator can be installed at a sufficient distance from the walls so that additional elements, such as a stepper, can be installed on the back of the rack.
