Description

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

Known simulator [RU 62338, U1, A63B 21/00, 10.04.2007], containing a support frame, a load fixed on the support frame with the ability to move, handles for lifting a load by a training athlete, interconnected with the load, while the simulator is equipped with two levers, pivotally fixed on an axis in the upper part of the support frame, on one of the levers there is a load with the possibility of moving and fixing it relative to the lever, and on the other lever there are handles for lifting the load by a training athlete, while the levers are rigidly connected to each other and are located on one side relative to the axis of rotation in such a way that the zone of movement of the lever with handles for the training athlete and the location of the training athlete are outside the zone of movement of the lever with the weight.

The disadvantage of the device is the relatively narrow functionality that does not allow, in particular, to perform strength exercises with a change in the relative position of both hands, which excludes the possibility of applying loads to individual muscle groups.

There is also known a device [Trainer AeroFIT IT 9330, www.proftren.ru], which belongs to the class of cargo block trainers, containing a vertical body with a floor installation, in which two packages of weights are placed and which is equipped with upper and lower floor arcuate elements, between the ends of which vertical racks, each of which is equipped with a carriage connected by a cable system with the corresponding package of weights, as well as a handle connected to the end of the corresponding cable.

This device allows you to perform strength exercises with a change in the relative position of both hands under load, but has a relatively large size, which limits the possibility of its use in health care organizations and at home.

In addition, there is a known simulator [RU 23052, U1, A63B 21/06, 10.05.2002], containing simulators installed on the supporting surface, spaced apart and fastened in the upper part by beams, each of which contains a supporting frame with two posts, serving to move the package of loads by means of a cable-block system with handles (rods), moreover, in the upper and lower parts of the supporting frame, the blocks are mounted with the possibility of turning around a vertical axis, the package of loads includes a means for setting the required load, and in the middle of the supporting frame between its vertical elements, a handrail is installed for the user, while the number of training equipment is three and they are spaced apart in such a way that the plane passing through the vertical symmetry axes of the supporting frames, respectively, of the first and second training equipment is perpendicular to the plane passing through the vertical symmetry axes of the supporting frames, respectively of the second and third exercise facilities, races the standing between the spaced first and second training devices is selected within 130-180 cm, the distance between the spaced second and third training devices is selected within 180-300 cm, while the beams that fasten the upper parts of the training devices together have a number of holes to ensure fastening training facilities within the specified limits of their spacing among themselves, the upper horizontal element of the supporting frame of each training facility is made with the possibility of its installation at different levels relative to the supporting surface within 180-250 cm.

The disadvantage of this technical solution is the relatively large dimensions even when performing strength exercises with a change in the relative position of the two arms under load, since for each of them a separate supporting frame with a package of weights is used. This limits the possibility of its use in treatment and prevention organizations and at home. In addition, the known device has a relatively high complexity, since it requires the use of at least two packages of weights and the corresponding means of placing (supporting frames) and fastening the packages of weights in them.

Close in technical essence to the proposed one is a power simulator [RU 172086, U1, A63B 21/018, 28.06.2017], containing a rectangular 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 between its vertical struts a package of goods moved by means of a cargo cable, as well as the first and second rods and a front vertical rack, fixed on the vertical rack of the supporting frame using the upper and lower transverse elements, a double carriage fixed on the front vertical rack, a suspension block fixed to the cargo cable, and a traction cable, the ends of which are connected through the suspension block to the corresponding first and second rods.

The disadvantage of this technical solution is the relatively large dimensions due to the presence of the front vertical rack, which reduces the possibility of its use in medical and prophylactic organizations and at home, where restrictions on the area occupied by the simulator are possible. In addition, most of this technical solution does not allow the use of additional options that expand the functionality of the simulator.

The closest in technical essence to the proposed one is a power trainer (Fig. 10), presented in two versions [Free Motion Fitness Live Axis, represented by two models F704 "High Pull" (pull from the top) and F702 "Low Pull" (pull from the bottom) , see https://www.youtube.com/watch?app=desktop&v=-KZD2TXTIzQ]. In this technical solution, the pulling load on each of the handles (or only the lower ones, or only the upper ones) is 25% of the weight of the weight block, which limits the possibility of performing exercises with rods for the handles with a more complete load and limits the variability of the use of the simulator.

Thus, the disadvantage of the closest technical solution is its relatively low variability due to limited functionality, since the traction rods in the initial position are located either only from above or only from below, therefore, each of the execution options can be used to perform exercises of only a certain type with an incomplete of the possible loads.

The task of this useful model is to create a simulator with wider variability and providing the ability to perform a wider range of strength exercises when placing the rods in the initial position both from below and from above with a more complete use of the load block parameters with practically the same weight and size characteristics of the simulator and ensuring the expansion of the arsenal of technical means used as strength training equipment.

The required technical result consists in expanding the variability and functionality of the simulator for performing a wider range of strength exercises, as well as in expanding the arsenal of technical means used as strength simulators.

The problem is solved, and the required technical result is achieved by the fact that the device contains a supporting structure vertically installed on the supporting surface with the first and second vertical struts, made with the possibility of placing between them a package of loads moved by means of a cargo cable, as well as the first pair of rods, the first and the second handle of which is located in the upper part of the first and second vertical struts, respectively, and connected to the corresponding upper ends of the traction cable, the second pair of rods, the first and second handles of which are located in the lower part of the first and second vertical struts, respectively, and connected to the corresponding the lower ends of the traction cable, while the supporting structure is equipped with movable and fixed blocks, bent around by the load and traction cables, forming the chain hoists of direct and reverse action, ensuring the transfer of traction forces to the load package from the first and second pairs of rods.

The power trainer contains the first 2 and second 3 vertical struts made with the possibility of placing between them a package of weights 6, moved with the help of a cargo cable 7 along guides 8 installed between the upper 4 and lower 5 connecting elements of the supporting structure.

In addition, the power trainer also contains a first pair of rods 9, the first 9-1 and second 9-2 handles of which are located in the upper part of the first 2 and second 3 vertical struts, respectively, and are connected to the corresponding upper ends of the traction cable 10.

In addition to the noted, the power trainer contains a second pair of rods 11, the first 11-1 and second 11-2 handles of which are located in the lower part of the first 2 and second 3 vertical struts, respectively, and are connected to the corresponding lower ends of the traction cable 10, while the carrier the structure is equipped with movable and fixed blocks, bent around by load and traction cables, forming chain hoists of direct and reverse action, ensuring the transfer of traction forces to the package of loads 6 from the first 9 and second 11 pairs of rods.

The load cable 7 forms the first and second load cable contours shown in FIG. four.

In the first circuit (Fig. 4) of the cargo cable, the cargo cable 7 itself passes through the movable first block 12. One free end of the cargo cable 7 in the first circuit is connected to the package of weights 6 through a coupling with a bearing. The second free end of the cargo cable 7 in the first circuit is connected to the lower bracket 52 also through a sleeve with a bearing. Couplings with bearings are designed to relieve internal stresses in the cable caused by its possible twisting when passing through the blocks. The first contour of the cargo cable 7 together with the first block 12 form a reverse-acting chain hoist, transmitting the traction force F = 2P to the axis of the first block 12 (hereinafter, without taking into account the resistance forces in the blocks), where P is the weight of the load package 6.

In the second circuit of the cargo cable, the cargo cable 7 itself passes through the movable second block 13, which is rigidly connected to the first block 12. The second circuit of the cargo cable 7 together with the second block 13 form a chain hoist of direct action, and as a result of the connection of the first 12 and second 13 blocks a combination of direct and reverse action chain hoists, which allows the same tractive effort F = P to be transmitted to each of the branches of the second circuit of the cargo cable 7. One free end of the cargo cable 7 in the second circuit outputs the load force to the point 36 of the pulling force F = P. The second free end of the cargo cable 7 in the second circuit through the stationary fourth block 15 goes to the movable fifth block 16 (connected to it through a coupling with a bearing), transmitting the traction force F = P to its axis.

Two loops for the cargo cable 7 are necessary to ensure the possibility of outputting the total weight of the package of loads 6 to each of the two points - simultaneously, i.e., to the third block 14 and the fifth block 16, to which the free ends of the cargo cable 7 in the second circuit go.

To output the same loads on the first 9 and second 11 pairs of rods, a traction cable 10 is used. It also forms two circuits - the third circuit of the traction cable and the fourth circuit of the traction cable (Fig. 5).

In the third circuit of the traction cable, the traction cable 10 itself passes through the movable fifth block 16, forming a direct-action chain hoist with the transmission of traction force F = P / 2 to each of the branches of the third circuit of the traction cable 10. The fifth block 16 is fixed on the carriage of the fifth block 50 to provide linear movement along the vertical guide of the fifth block 41 in a plane parallel to the plane of the package of loads 6. One free end of the traction cable 10 in the third circuit passes through the fixed sixth block 17, the movable seventh block 18 (is fixed for the third circuit of the traction cable 10), a pair of fixed the eighth 19 and the ninth 20 blocks and goes to the third point 37 of the output of the tractive effort, transmitting the force F = P / 2. The other free end of the traction cable 10 in the third circuit passes through the fixed tenth 21 and eleventh 22 blocks and goes to the fourth point 38 of the traction force output, also transmitting the force F = P / 2.

In the fourth circuit of the traction cable, the traction cable 10 itself passes through the movable twelfth block 23, which is rigidly connected to the seventh block 18, to the axis of which the traction force F = P is transmitted, forming a combination of direct and reverse chain hoists with the transfer of traction force F = P / 2 for each branch of the fourth traction cable circuit. The seventh block 18 and the twelfth block 23 are fixed on the carriage of the seventh and twelfth blocks 53 to ensure linear movement along the vertical guide of the seventh and twelfth blocks 51 in a plane parallel to the plane of the load package 6. One free end of the traction cable 10 in the fourth loop passes through a pair of successive fixed thirteenth 24 and fourteenth 25 blocks and goes to the first point 39 of the output of the tractive effort, transferring to it the tractive effort F = P / 2. The other free end of the traction cable 10 in the fourth loop passes through a pair of successive fixed 15th 26 and 16th 27 blocks and goes to the second point 40 of the traction force output, transmitting traction force F = P / 2 to it.

Thus, with the help of the third contour of the traction cable 10, the traction load is output to the third 37 and fourth 38 points of the load output. With the help of the fourth contour of the traction cable 10, the traction load is output to the first 39 and second 40 points of the load output. On the third 37 and fourth 38 points of the load output, to which the free ends of the traction cable 10 in the third circuit of the traction cable 10 come out, half of the weight of the package of loads 6 is transferred, because the third contour of the traction cable 10 together with the movable fifth block 16 form a chain hoist of direct action. Due to the combination of the seventh block 18, rigidly connected to the twelfth block 23, a combination of two chain hoists is formed - direct and reverse action, which makes it possible to bring half of the weight of the package of loads 6 to the first 39 and second 40 points of the load output, to which the free ends of the traction cable go 10 in the fourth traction cable loop 10.

Thus, the same load is transferred to each of the four points of output (the first 39, the second 40, the third 37 and the fourth 38), equal to half the weight of the package of loads 6.

The free ends of the third and fourth circuits of the traction cable 10 are connected to the rear brackets of the carriages 49 (respectively, the first lower 44, the second lower 46, the first upper 42 and the second upper 43 carriages with latches) through couplings with bearings to relieve internal stresses in the cable caused by its possible torsion when passing through the blocks.

The traction cable 10 also forms the fifth and sixth traction cable contours (Fig. 6).

The traction cable 10 in them passes, respectively, through double blocks (seventeenth 28 and eighteenth 29 blocks and nineteenth 30 and twentieth 31 blocks) of the first 42 and second 43 upper carriages and double blocks (twenty-first 32 and twenty-second 33 blocks and twenty-third 34 and twenty-fourth 35 blocks) of the first 44 and second 46 lower carriages and transmits the tractive effort to the sticks 9-1, 9-2 and 11-1, 11-2.

When pulling on the upper handles 9-1, 9-2, the upper carriages move down along the guides, while the lower carriages remain stationary - as a result, direct action pulley blocks are formed. Likewise, when pulling on the lower sticks, the lower carriages move up along the guides, while the upper carriages remain stationary. As a result, direct action pulley blocks are also formed. In this case, a quarter of the weight of the package of loads is transferred to each handle 6. The latches of the upper and lower carriages are designed to exclude the displacement of the opposite carriages from the extreme positions when performing exercises - fixing, respectively, the first lower carriage with a lock 44 and the second lower carriage with a lock 46 when performing the exercises of the first 9-1 and the second 9-2 with the handles of the first pair of rods 9, or the first upper carriage with a lock 42 and the second upper carriage with a lock 43 when performing the exercises of the first 11-1 and the second 11-2 with the handles of the second pair of rods 11.

For double blocks of carriages in the pulley blocks, only one of the blocks works (the lower block at the upper carriages and the upper block at the lower carriages), the second one ensures the tension of the cable so that the traction cable does not come off during exercise.

Thus, in the proposed strength simulator, a traction load equal to a quarter of the weight of the package of weights 6 is transmitted to each of the four handles, which significantly expands the functionality of the simulator by increasing its variability, since exercises can be performed using rods both from above and from below, in contrast to from a device selected as a prototype, in which the same thrust load is transferred only to the upper (for the F704 model) or only the lower (for the F702 model) links. The indicated gain in strength 1: 4 when transferring the traction load to the handles 9-1, 9-2 and 11-1, 11-2 is accompanied by a corresponding loss in distance, allowing to provide the length necessary for performing the exercises (both with one and with two hands) pulling the traction cable. With the free movement of the package of weights 6 from the bottom to the top point, which is about 100 cm, each of the two handles of the simulator (9-1 and 9-2 of the first pair of rods, or 11-1 and 11-2 of the second pair of rods) can be distant by 200 cm from the starting point when working with both hands simultaneously, which is sufficient to perform exercises on all major muscle groups.

In addition, the proposed simulator implements the output of the traction load, equal to the full weight of the package of loads 6, to an additional fifth load output point 36 (Fig. 7), due to which it becomes possible to further expand the functionality as a result of adding additional options. Thus, in the proposed strength simulator there are five points of load output, while in prototype devices there are only two (either from the top or from the bottom) and a fifth load output point is added with full output of the weight of the package of loads 6, which allows even more expand the functionality by introducing additional options, for example, for pull-ups on the bar and push-ups on the uneven bars with the ability to regulate the load by using a package of weights as a counterweight to the user's own weight (Fig. 8), or a wide grip row using a special bar (Fig. 9 ). When pulling from the additional fifth point 36 of the load output, there is no gain in force (with the simultaneous absence of a loss in distance), and the length of the pulling out of the cargo cable corresponds to the free travel of the load package 6 from the bottom to the top point, which is about 100 cm, which is sufficient for the implementation of the indicated additional options.
