Abstract

FIELD: equipment used for sportsmen exercising, as well as for patient rehabilitation after trauma of locomotor apparatus, prophylaxis of diseases caused by motionless mode of life, and for training of vestibular apparatus.

SUBSTANCE: exercising apparatus has E-shaped base and front and rear poles immovably fixed on base. Seat is movably mounted on base and coupled to loading device through bar. During exercising of sportsman, seat reciprocates in planar-parallel plane. Guide for load is positioned for changing angle of inclination to line of horizon by means of mechanism equipped with retainer. Pusher is pivotally connected to bar. Load is made from metal. Mechanism for changing inclination angle to line of horizon is made of rack type. Changing of loading is determined from formula: m=sin α·M, where m is loading of user's muscles; α is angle between guide and line of horizon.; M is weight of load. Motion amplitudes of seat and loading mechanism are extending in parallel and adjacent to one another.

Description

The training device belongs to simulators and is intended for the training process of athletes, rehabilitation of patients after injuries of the musculoskeletal system, prevention of diseases caused by an immobile lifestyle, training the vestibular apparatus.

Multifunctional simulators usually have large overall dimensions, for example, a device for training according to AS No. 1477433. Small-sized simulators, as a rule, are not very functional and are designed to work out one or two muscle groups, for example, a training device according to RF patent No.2016594 only for the development of shoulder biceps.

The closest analogue of the claimed invention is a training device containing a base, a fixed stand and a movably mounted seat connected to a loading device with a bar, and a load guide installed with the possibility of changing the angle of inclination to the horizon using a mechanism with a latch (see copyright certificate No. 1358973, CL A 63 B 23/04, 1987).

The technical result of the invention is to increase the efficiency of use, reducing the size.

The specified technical result is achieved by the fact that the known training device containing a base, a fixed stand on it and a movably mounted seat connected to a loading device with a bar, and a load guide, mounted to change the angle of inclination to the horizon using a mechanism with a latch, according to the invention has a pusher pivotally connected to the bar, and additionally fixed on the base of the stand, while one stand is the front, and others hiding the back, and the seat during the training process performs plane-parallel, reciprocating motion, and the base is made E-shaped.

The load is made of metal, while the angle of inclination of the guide for the load to the horizon changes using a rack and pinion mechanism, and the load change is determined by the formula m = sinα · M, where

m is the load on the muscles of the trainee,

α is the angle between the guide and the horizon line,

M is the weight of the cargo.

The amplitudes of the seat and the load mechanism are located side by side in parallel.

The invention is illustrated by drawings, where

figure 1 shows a training device in isometric projection;

figure 2 - in frontal projection with a range of operation of the moving parts;

figure 3 shows the position of the cargo 14 relative to the horizon line;

figure 4 shows a graph of the load applied by the athlete, from the angle of movement of the load and the horizon shown in figure 3;

figure 5 shows the six positions of the trainee depending on the study of a particular muscle group.

Description of the device in statics: 1 - base, 2 - rear rack, 3 - leg handle, 4 - seat, 5 - axis, 6 - front rack, 7 - emphasis for legs, 8 - rod, 9 - rack for fastening the load device, 10 - pusher, 11 - hinge for connecting the rod and pusher, 12 - frame of the loading device, 13 - rollers, 14 - load, 15 - guide, 16 - hinge for connecting the frame and rail, 17 - rack and pinion mechanism, 18 - rail, 19 - the handle of the front rack, 20 - the handle of the rear rack, 21 - the handle for the biceps of the hands, 22 - the seat post, 23 - the hinges of the load device.

The training device contains a movable unit: a seat 4 and a load device 12, 13, 14, 15, 23, interconnected by a rod 8 and a pusher 10 and a fixed unit: base 1 and racks 2 and 6. Based on 1 E-shaped bearings axis 5 is fixed. Two seat racks 22 and a rod 8 are rigidly fixed on the axis, the third seat post is movably fixed on the base 1, which ensures plane-parallel movement of the seat. The rod 8 and the pusher 10 are interconnected by a hinge 11 on the bearing.

The load device consists of a metal load 14, which, with the help of a pusher 10, moves along the guide 15 on the bearing rollers 13, the guide is rigidly connected to the frame of the load device 12. The angle of inclination α between the guide and the horizon is changed by a rack and pinion mechanism 17. The load device is simply manufacture and operation, in contrast to cable systems, for example, "The load unit of a sports simulator", AC No. 1443898 A1, "Cargo carriage of the load node of a power simulator", AC No. 2159651 C1, "Device TVO for muscle training "AS №1540841 A1, which are short-lived and difficult to operate. On the base are also fixed motionless racks rear 2 and front 6.

Operating principle. Figure 2 shows the amplitude of the movement of the training device from position I — solid line of the drawing to position II — dashed line of the drawing.

Trained, pushing hands from the handle 19 from 7 legs or pulling at the handles 20, 21 with arms and 3 legs, performs translational movement of the seat 4 from position I to position II, axis 5 rotates counterclockwise with the bar, which pusher 10 moves the load 14 from position I to position II, the return movement is due to the weight of the load when the trainee weakens the effort in the muscles.

Sitting facing the load device of figure 5, the trainee can perform the following exercises:

- push-ups from the handle 19 in this case, the pectoralis major muscles and triceps muscles of the shoulder (triceps) of Fig.5 ^a ;

- push-ups from the stop with 7 legs, all leg muscles of Fig.5 ^{b work} ;

- leg extension, catching on the handle 3, the quadriceps of the legs of FIG. 5 ^{c work} .

Sitting with his back to the load device, the trainee performs the following exercises:

- pulling the handle 20, working bicapital back muscles and shoulder muscles (hamstrings) 5 ^g;

- pulling up to the handle 21, the biceps of the shoulder of Fig. 5 ^d work in isolation;

- bending of the legs, catching on the handle 3, the biceps femoris muscles of FIG. 5 ^{e work} .

The load on the muscles during training changes on the load device using the rack mechanism 17, changing the angle between the frame of the load device and the horizon line. The angle can be changed from 90 ° to 10 ° -15 °, the smaller the angle α, the lower the load of Fig.3. With a cargo weight of 14 per 100 kg and at α = 90 °, the load will be about 100 kg. Changing the angle α of FIG. 3, we consider the graph of the function m = sinα-100 of FIG. 4.

At α = 60 °, sin60 ° -100 = 0.86-100 = 86 kg,

at α = 45 °, sin45 ° -100 = 0.7-100 = 70 kg,

at α = 30 °, sin30 ° -100 = 0.5-100 = 50 kg,

at α = 15 °, sin15 ° -100 = 0.25-100 = 25 kg and so on.

The trainee can change the load without leaving the place with the help of a rack and pinion mechanism, fixing the desired angle. Figure 1 - minimum load, figure 2 - maximum load.

The proposed training device is a multi-functional mini-gym. It provides the study of the muscles of the chest, back, legs, arms and at the same time has dimensions of no more than 2 × 1.8 × 1.5 meters.
