Description

The utility model relates to sports strength training equipment and can be used for training and developing muscles.

A power universal complex (RU 2725117, publ .: 29.06.2020 Bull. No. 19) is known from the prior art, which is a prefabricated structure held on a solid platform. It includes two interconnected zones, one of which is made in the form of a frame like a triangle, made of three vertically attached metal profile pipes. One contains a trolley with a cable attached from the inside vertically, intended for cargo, with the possibility of fastening, moving and smoothly sliding vertically, and the other two also contain a fastening device with a roller located between them with the possibility of fastening and moving vertically. These profile pipes are connected at the top by a three-sided fastener, on which a roller is attached, and the trolley intended for cargo has a lock on the outside, to the crossbar of which a clutch cable with a handle is attached. In the lower part, the trolley has a shock absorber stop, which is attached to the platform base. The second zone is made in the form of a rectangular vertically oriented frame, on one side of which removable sports equipment are fixed on two vertical profiles, on the opposite side of which a movable structure is also fixed on two vertical profiles with the possibility of fastening and moving vertically. The vertical profiles are connected at the top with each other, and metal hinges are located at the corners, and in the lower horizontal part of the rectangular vertically oriented frame there is a structure made in the form of a trolley, with the possibility of fastening, moving and smoothly sliding along a horizontally fixed rod and a footrest with the possibility of fastening and moving. The disadvantages of this design are:

- inability to work with two limbs along different trajectories, the carriage travel is strictly in a vertical position;

- the inability to turn the carriage and make the handle on the left, while not losing the functionality of the location of the rollers;

- the lack of a completely collapsible carriage and the ability to assemble in various combinations;

- using only one size of rollers.

The closest in technical essence is a power trainer (RU 172086, publ .: 28.06.2017 Bull. No. 19), which contains a rectangular-shaped supporting frame vertically installed on the supporting surface with vertical posts and upper and lower connecting elements, which is made with the possibility of fastening on it a cargo cable and placing a package of cargoes between its vertical posts, moved by means of a cargo cable along the guides installed between the upper and lower connecting elements, as well as the first and second rods, the front vertical post, fixed on the vertical post of the supporting frame using the upper and lower cross members, a double carriage fixed on the front vertical rack, a suspension block attached to a cargo cable, as well as a traction cable, the ends of which are connected to the corresponding first and second rods through the suspension block and blocks of the double carriage. The disadvantage of this technical solution is that the carriage contains a lock on the front side, which interferes with the range of rotation of the roller bracket and reduces the possibility of use.

The disadvantage of the known technical solutions is that simulators and complexes include several systems of cables. Also, the disadvantage is the location of the cable is not on the same line of rotation of the roller bracket.

The declared utility model solves the problem of simultaneous work with two limbs.

This problem is solved by the fact that the carriage of the simulator consists of a frame, rollers for pulling the cable, the frame of the carriage is a square tube made with the possibility of movement along the guide, with a frame lock on the side mounted on the guide, the carriage also contains two bearing housings on which two bracket for cable rollers, each bracket has two cable rollers, bearing housings are welded to the carriage body with strips.

The technical result provided by the given set of features is the universality of the carriage and, therefore, a wider range of applications in simulators.

The claimed technical solution will be used in simulators for the ability to simultaneously work with two limbs and also for the possibility of changing the removed load (100% and 50%) without changing the weight of the burden.

The technical solution is based on the simultaneous exit from one carriage of two outputs (ends) of one cable, with the possibility of their movement along free vectors of motion relative to each other, i.e. the practitioner can work with two limbs simultaneously along different trajectories of movement and additionally has the ability to adjust the carriage vertically (or at an angle relative to the vertical), which in turn increases the number of angles of attack (working out) of the muscles.

The simulator includes vertical guides 1 with crossbars 2, thus forming a ladder. Vertical rails have stops (brackets) for wall mounting. A horizontal bar 3 is installed in the upper part. Vertical guides from above and from below are reinforced with horizontal supports. On the side of the ladder (to the right or to the left), horizontal supports continue, on which the vertical guide 6 of the carriage is attached. In addition, a long 8 and short 4 handrails are located on the side, while the long handrail is attached to the horizontal supports, and the short handrail to the vertical rail with crossbars.

The carriage 7 consists of a frame 12, two bearing housings 13, four rollers 15 for the cable 11 and two brackets 14 rollers. The carriage frame 12 is a square tube with the frame retainer 16 installed on the side on the rail 6. Slats with bearings 13 are welded to the carriage frame 12 for mounting the brackets 14. The brackets 14 are designed to be placed inside two rollers 15 and the strips for attaching to the bearings.

The guide 6 of the carriage is provided with holes for fixing the carriage frame.

The carriage body moves along the guide and is fixed in the desired position with the help of the latch. The latch contains a handle 17 and a strip with threaded holes 18 for attaching the body to the guide. The latch with the handle is preferably located on the right side of the carriage. This allows the practitioner to comfortably grip with one hand (right) and at the same time open the latch to change the position of the carriage height. It is also possible to turn the carriage over and make the handle on the left, without losing the functionality of the roller arrangement. The bracket 14 of the rollers is made in such a way that when the bracket is rotated, the cable that goes around the roller is in line with the axis of rotation of the bracket. This allows the cable to move correctly, i.e. in the extreme positions of the carriage, the cable does not run over the roller jaws, and this, in turn, does not destroy the integrity of the cable and rollers.

The carriage has the ability to move both along a vertical guide and at an angle relative to the vertical.

This carriage is completely collapsible and universal and can be assembled in various combinations, which allows it to be positioned on the left and right sides of the load block without changing the cable. Can also be positioned in front of the load block. In this case, only one roller size is always used.

The cable is stretched in such a way as to reduce its length, which means to reduce the cost of the final product. Also, with a decrease in the length and number of cables, the reliability of the structure increases, since the nomenclature of mating elements decreases. Also, with the declared location of the cable and rollers, the space between the movable carriage and the central line, which runs along the load blocks, is saved, due to the fact that there is no connection of the two cables, the space is reduced, which means that the equipment will be more compact. The advantage of this system is that it is possible to work in all angles (from -80 to +80 degrees with respect to the perpendicular, which runs along the center of the front part of the carriage) of the frontal part of the carriage both with one exit and with two simultaneously. At the same time, the load at the exit from the carriage changes, which means that the overall functionality of the entire system increases, since nothing interferes with the movement of the roller housing in the front part. The advantage is that you can also work with two roller carriages at once, doubling the load. With this arrangement of the rollers, it is possible to locate the cable not only to the left and right, but also in front of the load block.

The cable is pulled in the following way. The cable rises from the load block up and stretches along the frame, then one end goes to the carriage from above, and the other through one roller changes its motion and enters from the bottom of the carriage. Thus, there are no unnecessary changes in the line of movement of the cable, which means that the reliability increases and the material consumption of the product decreases, i.e. the cost price is reduced.

The vector of the cable movement when entering the carriage is clearly parallel to the guide carriage, which increases the reliability of the structure, since the cable at the extreme positions of the carriage will not rub against the roller jaws due to the mismatch of the cable exit points from the upper or lower rollers installed before entering the carriage in motion cable and points of entry of the cable into the carriage relative to the movement of the entire carriage. Geometrically, these two straight lines should be parallel, only in this case the cable will work correctly without unnecessary friction on the jaws of the rollers.

The weight block is a set of tiles that move along two guides. To reduce the friction of the tile against the guide, there is a bushing with a low coefficient of friction against metal, which is inserted into the tile. The holes for the slide guides are equally spaced from the center of the workpiece. The central hole is for the "flute" to enter through all the tiles. The "flute" is fixed to the top tile and has an equal number of holes in the tiles. Each hole on the flute is opposite each tile and is needed to change the weight. This is done by connecting the adjusting pin and the required tile that matches the required load.

The carriage moves along a vertical guide that can be tilted. The position of the carriage is fixed using a latch. The carriage has on the front part a bar with threaded holes for fastening the bearing housing. This allows you to change the entry of the cable into the carriage, i.e. the top entry of the cable can be on the left with one assembly scheme, and on the right with the other, which indicates the versatility of the design.

Thus, thanks to the claimed design of the carriage, it is possible to move both along a vertical guide and along an angle with respect to the vertical, two outputs (ends) of one cable, with the possibility of their movement along free vectors of motion relative to each other. The practitioner can work with two limbs simultaneously along different trajectories of movement and additionally has the ability to adjust the carriage vertically (or at an angle relative to the vertical), which in turn increases the number of angles of attack (working out) of the muscles. It is also possible to work when one cable outlet is pulled, while the load at the outlet will be 50% of the weight of the burden. When pulling two cable outlets at once, the load will be 100% of the weight of the load, and this increases the functionality and versatility of the equipment.
