This invention relates to the field of sports, namely, muscle training devices.

The purpose of the invention is to increase the effectiveness of training by improving the exercises performed.

FIG. 1 shows a device for training muscles, a general view, in FIG. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. one; in fig. 4 shows a section B-B in FIG. 3; in fig. 5 is a section of YYD in FIG. 3; in fig. 6 — node 1 in FIG. 3 (planetary gear with friction); in fig. 7 - node II in FIG. 1 (device when the pedal shaft is locked); in fig. 8 is a section DD-D in FIG. 2 (fixing the fork in the position for pedaling); in fig. 9 shows section EE of FIG. eight.

The muscle training device has frame 1 in the form of two parallel rods 2 with jumpers 3-5. On the front bridge 2, a sleeve 6 is fixedly mounted (FIGS. 8 and 9), in an annular recess of which a split sleeve 7 is hingedly mounted, consisting of two caps 8 and 9 connected by means of bolts 10 and nuts 1. The cover 8 of detachable sleeve 7 is fixed an arm 12 with a fork 13 (Figs. 7, 2 and 3) is attached, in which a means 15 is applied to the slide bearings 14 to create a load (Figs. 1 and 2), including a drum 16 with trunnions 17. On the shaft 18 of the drum 16 are mounted pedals 19, and on the rim 20 of the drum there is a fixedly mounted handle 21 with handles 22.

Inside the drum 16, a planetary mechanism and a flywheel 23 with an overrunning clutch 24 containing rollers 25 are mounted on the shaft 18. The flywheel 23, due to the bearings 26 and the rollers 25, is capable of one-sided rotation relative to the overrunning clutch 24 in the direction of the arrow I. rotate relative to shaft 18 due to bearings 27.

The planetary mechanism (Fig. 3 and 4) contains the carrier 28, fixedly mounted3. A device according to claim 1, characterized in that the means for creating a variable in magnitude load is made in the form of a band brake, the tape of which covers the rim of the flywheel, with one end of the tape fixed to the housing and the other connected to the tensioning mechanism mounted on the housing.

by means of a key 29 on the shaft 18 of the pedal mechanism and the drum 16, the central wheel 30 fixedly mounted on the inner wall of the drum 16, satellites 31 mounted by means of axes

32 on the carrier 28, and the central wheel 33 fixedly mounted by means of a key 34 on the hub of the overrunning clutch 24. The satellites 31 are made with two wreaths of quince, and the crown a is engaged with

a fixed central wheel 30, and a crown in - meshed with a movable central wheel 33.

The planetary mechanism of the device can be equipped with central wheels 30 and 33 and a satellite 31 with a conical

friction gearing (Fig. 6).

In order to create adjustable workloads on the pedals x 19 and the knob 21, the means 15 for creating the load are provided with a band brake (Fig. 5), the tape 35 of which covers the rim of the flywheel 23. One end of the tape 35 is fixedly fixed by means of a bracket 36 on the rim 20 of the drum 16 and the other end of the tape 35 comprises a bracket 37, in which a screw hole 38 is screwed into a threaded hole, the head of which is supported on the bracket 39 installed in the groove 40 of the rim 20 of the drum 16.

The load generating means 15 can be installed on the device in different working positions: in the K position for occupying in rowing mode and in the L position for occupying in pedaling mode.

Fixing the means for creating a load in position K (Fig. 1) is dried by rotating the head 41 of the screw 42 (Fig. 7) passing through a hole in jumper 4 of the frame 1 of the device and wrapped in a threaded hole in the plug 13 of the lever 12. In this case, the pedals 19 abut against the frame 1, which makes it possible to block their rotation.

The fixing means for creating a load in the position L is carried out by means of a pin 43, passing through the holes "s" in the walls of the sleeve 6 and through one of the holes d, e or / of the split sleeve 7. The device operates in rowing mode as follows.

The athlete, sitting in the seat 44, cyclically moves the handle 21 in the direction of the arrows M and N. In this case, the movement of the handle 21 in the direction of the arrow M is carried out with resistance, and in the direction of the arrow H - free, which simulates the conditions of rowing in the boat.

When the handle is moved in the direction of arrow M, the drum 16 rotates relative to the shaft 18, which is locked in rowing mode. Together with the drum 16, the central wheel 30 rotates, causing the satellites 31 to rotate on the fixed carrier 28, which, in turn, rotate the central wheel 33 together with the overrunning clutch sleeve 24. In this case, the rollers 25 are wedged between the overrunning clutch sleeve 24 and the flywheel 23, which causes rotation of the flywheel. Due to the fact that the rim of the flywheel 23 is covered by the tensioned band 35 of the band brake, on the handle 21 there is resistance to its movement.

When the handle is moved in the direction of the arrow H, the planetary gear wheels rotate in the opposite direction, while the rollers 25 do not prevent the hub of the overrunning clutch 24 inside the flywheel 23, and the flywheel is stationary, which allows the free movement of the handle 21.

The operation of the device in the pedaling mode is carried out as follows. The screw 42 is unscrewed and the lever 12 is moved in the direction of the arrow T to the position L, in which it is fixed with the tongue 43, and the handle 21 is lowered until it stops against the floor surface. The athlete, sitting on the seat, rotates the pedals 19 in the direction of the arrows P or P. At the same time, the pedals rotate in the direction of the arrow P

0 is carried out with resistance, and in the direction of arrow P is free.

When the pedals are rotated in the direction of the arrow P, the shaft 18 rotates together with the planet carrier 28 and the satellites 31 roll over the fixed central part

5 to the wheel 30. The satellites 31 rotate the central wheel 33 together with the overrunning clutch sleeve 24. In this case, the rollers 25 are wedged between the overrunning clutch sleeve 24 and the flywheel 23, which causes the flywheel to rotate. Due to the fact that the rim of the flywheel 23 is covered by the tensioned band 35 of the band brake, pedal x 19 causes resistance to their rotation.

When the pedals are moved in the direction of the arrow P, the driver 28 and the wheels of the planetary mechanism rotate in the opposite direction, while the rollers 25 do not impede the rotation of the hub of the overrunning clutch 24 inside the flywheel 23, and the flywheel is stationary, which ensures free rotation of the pedals 19.

The adjustment of the load on the handle 21 or pedals x 19 is ensured by tensioning the belt 35 around the rim of the flywheel 23 by turning the screw 38.
