Abstract

The aim of the invention is to increase the efficiency of using the simulator by providing a real opportunity to simulate the work of an athlete. The device comprises a frame 1, a carriage 2 for an athlete, an emphasis 3 for legs and a loading mechanism, the latter including a flywheel with blades. The flywheel is mounted in a casing made in the form of a disk 9 with a protective grill. Windows 11 are made on the disk and the gate valve 12 is fixed. By means of the chain 14 and the shock absorber cord, the flywheel is connected to the handle 13, the bed and the carriage. 4 ill.

FIELD OF THE INVENTION This invention relates to training sports equipment, which allows simulating the movements of an athlete in a sports laboratory.

A device for training rowers is known, comprising a bed with a carriage for accommodating an athlete, a load mechanism located in the form of a flywheel with air resistance blades connected through a chain transmission with a handle, and a shock absorber with a bed and carriage.

Its disadvantage is the inability to fully simulate the working conditions of the rower in terrestrial conditions.

The aim of the invention is to increase the efficiency of use by providing real conditions.

Figure 1 shows the device, side view; figure 2 is the same, plan view; in Fig.Z - t govo-amrrtization body, side view; figure 4 - load mechanism, in the context.

A device for training rowers, for example, an academic boat, includes a frame 1 on which a carriage 2 is located to accommodate the athlete, foot rests 3 and a loading mechanism. The load mechanism is made in the form of a flywheel 4 with blades 5 of air resistance. Flywheel mounted on shaft b. An overrunning clutch 7 is installed inside the flywheel, on the sprocket 8. The flywheel is mounted in a casing including a disk 8 and a protective grill 10 mounted on the disk. Windows 11 are made on the disk and the gate valve 12 is fixed. The loading mechanism is equipped with a towing member connected to the handle 13, interacting with the flywheel sprocket and made in the form of a chain 14 and a shock absorber cord 15. The cord is stored inside the frame through rollers 16 and one end connected to a chain, and the other end mounted on a bed. Device

equipped with an electronic meter. The flywheel is mounted with unidirectional rotation on the shaft through the freewheel 7.

The device is used as follows.

The athlete sits on the carriage 2, secures his legs on the stops 3 and grabs the handle 13. Having approached the carriage closer to

footsteps and pushing legs, stretches

chain with 14 arms, making the movement of the rower with straightening legs. Then the cycle of motions is repeated.

In doing so, flywheel 4 by means of a chain

14 enveloping the sprocket 8 is driven. When the flywheel with the blades 5 rotates, air resistance is created, and therefore, the required force equal to the stroke force.

The use of a vortex air drag device in the loading mechanism ensures the similarity of sensations with work on an academic boat.

The load control is provided by a slide gate 12, which changes the area of the windows 11 on the disk 9 to adjust the forces on the oar.

The return of the carriage with the athlete to the starting position is provided by the cord shock absorber 15.

Using an electronic calculating device, you can set the time interval and determine the energy intensity of the work performed, hold the set

pace and speed.

Thus, the simulator allows you to conduct training of various intensities, change the load and rhythm of movements.

The simulator can also be used by others to improve the functional state, strengthen the muscles of the back, abdominals, etc., reduce excess weight and as a means of dealing with physical inactivity.
