Description

The invention relates to sports simulators, combines a dumbbell and a carpal expander, and is intended as a sports simulator for the development of arm muscles and. muscle response.

There is a well-known sports bar, on both sides of the neck of which gyromotors are placed. This device can significantly reduce weight and increase training efficiency by loading a larger group of muscles, but nevertheless, in this case, the possibilities of the gyroscopic effect are far from fully utilized.

Closest to the invention is a gyroscopic training device comprising at least one gyromotor mounted in a hollow body mounted on an axis perpendicular to the gyramotor axis, a gyromotor body rotation drive and a handle fixedly mounted relative to the rotation axis of the gyromotor body. This device allows you to more fully use the capabilities of gyromotors to develop a larger group of muscles of the hands, shoulder girdle and the like, but cannot be used to strengthen the muscles of the hand and especially the fingers. In addition, this device does not allow dosing the load vi. It requires a stationary installation, since it is made in the form of a dumbbell and has very narrow training capabilities.

The proposed device solves all these problems due to the fact that the gyroscopic training device, comprising at least one gyromotor mounted in a shell mounted with the possibility of rotation on the axis perpendicular to the axis of the gyromotor, the rotation drive of the gyromotor body and a handle fixed fixed relative to the axis of rotation of the shell is equipped with a stand, an additional movable handle mounted with the possibility of reciprocating movement relative to a fixed handle and associated with the rotational drive of the housing shell, and the housing, rigidly connected to the fixed handle, consisting of two hemispheres, with compression springs placed between the handles, four parallel holes made in the movable handle. The rotation drive is made in the form of a screw pair, with the screw mounted on a movable handle, and the gull on a hollow body, the stands are equipped with a common housing lock, conductive elements, and a time relay. Two opposed gyromotors can be installed in the casing; the nut in the aforementioned screw pair can be rigidly mounted on the lower part of the hollow body. The length of the thread of the nut may be less than the maximum distance between

handles, the nut can be mounted in a hollow housing with the possibility of rotation and is equipped with a ratchet mechanism connecting it with the shell, and the movable handle is equipped with a stopper. with a tooth,

0 interacting with the shell, while with the handles apart, the gap between the ends of the screw and nut of the screw pair exceeds the height of the stopper tooth. Hemispheres of the body have an elastic coating.

5 This device has wider training capabilities, combining the advantages of a dumbbell and a hand expander, while it is possible to vary the load on the muscles due to

0 changes in the speed of the gyromotors by adjusting the time of its acceleration. The presence of two gyromotors makes it possible to obtain a double gyroscopic moment and a load that is symmetrical with respect to the brush, and removing the screw from the nut with the nut allows the shell to move around under the action of gyroscopic forces, the orientation of the load on the athlete's hand, application

0 ratchet mechanism and stopper allows you to set the shell with gyromotors at any angle from the initial position to change the direction of the action of gyroscopic forces on the athlete’s hand,

5 an elastic coating protects the device from shock loads.

Fig. 1 shows a section through a device with one gyromotor and with constant engagement of a screw pair; Fig. 2 shows a section through a device with two gyromotors and a nut, the dimensions of which allow the screw to be disengaged from it; Fig. 3 is a sectional view of a device where the movable handle is provided with a gear stopper and the nut is a ratchet mechanism.

The gyroscopic training device includes a housing consisting of two hemispheres 1 and 2 having an elastic coating 3. The hemispheres of the housing are bonded

0 screws.

On the upper part of the housing there is a cylindrical opening in which the upper 4 fixed and lower 5 movable handles are located, between which springs 6 are installed.

The lower 5 handle is mounted for reciprocating movement along the cylindrical opening of the housing. This handle has holes for the athlete’s fingers, as well as a hole

for the rod 7, in addition, this handle at the bottom is threaded.

Inside the hemispheres there is a shell, the cavity of which is formed by a sleeve 8, supported through bearings 9, 10 and 11 on the housing, and a sphere 12. The sleeve 8 is provided with a thread interacting with the thread of the handle 5, One or two gyromotors 13 are installed inside the shell cavity, and in the lower two slip rings 14 are secured to the parts of the sleeve 8 for supplying power to the gyromotors 13.

The training device is inoperatively mounted on the stand 15, while the collector rings 14 are in contact with the conductors 16. The stand is equipped with a latch with the left 17 and right 18 paws, the latter having a lever 19. The paws are pulled by a spring 20. A spherical tip t is placed between the paws. 7. The lever 19 is in contact with the microswitch 21, in the circuit of which a time relay 22, a switch 23 and a plug 24 are installed.

The device operates as follows.

The plug 24 is plugged in, the switch 23 is turned on, the time switch is set to a time selected on its scale, during which the accelerators of the massive gyromotors rotate in one direction.

After the time relay trips, the power supplied to the gyromotors is turned off.

To detach the device from the stand, the athlete lowers his hand into the cylindrical hole of the general body and lifts the thrust ring 7 up to the stop, while the spherical tip of the thrust rises, spreads the legs of the lock, rises further to the stop, and the legs of the lock are pressed against each other their protrusions come out of the grooves of the body and release the training device for lifting.

When the rod 7 rises up, the paw 18 exerts pressure on the microswitch 21 with its lever and, independently of the time relay, turns off the power when the device is lifted.

Hand muscle training is performed both by squeezing the handles and by raising and lowering the device along various paths.

When the handle 5 is moved upward due to the screw drive, the shell rotates together with the gyromotors 13. The gyroscopic moment developed by the gyromotors 13 will prevent this rotation, creating a load on the athlete’s hand.

When working with a trainee by moving the device in space (without

hand grips) for any motion paths that change the position of the axis of rotation of the gyromotors, there will be a gyroscopic moment acting on the hand and fingers, the magnitude of which will depend on the direction and speed of movement of the device in space. In this case, the effect will be manifested without applying a finger force to the handle 5.

The effect can be achieved by simultaneously squeezing the handles and changing the position of the axis of the gyromotors in space

Using the relay 22 time, you can adjust the speed of the gyromotors 13

by limiting their acceleration time, which will affect the compressive forces of the handles or the forces with which it will be necessary to move the device in space

To complicate the exercise by moving the handle 4, we remove the screw from the meshing with the nut in the screw pair (Fig. 2). This is achieved by making the nut height shorter than the maximum distance between the handles 4 and 5 (or the maximum value

lifting the screw, which is one and the same value) In this case, the shell with the gyromotor (gyromotors) will not be kept from turning under the influence of the procession of the gyromotors. The shell will be ps

turn around by changing the direction of the resultant forces acting on p; athlete In the load mode, various muscle groups will be on / off.

Ratchet gear

25 (FIG. 3) of nut 26, which is designed as an independent part and mounted on the sleeve 8 of the hollow body with the possibility of rotation, allows the handle 5 to rotate the hollow body with

with gyromotors at a certain angle and fix it in this position when the handle 5 returns to its original position with the help of a tooth 27, a stopper mounted on the handle 5, and a gear ring 28 mounted on the sleeve 8. Moreover, when moving the handle 5, it first disengages from the crown 28 the stopper tooth 27, releasing the shell for rotation, and then, due to the fact that the distance between the ends of the screw and the nut of the screw pair is greater than the height of the tooth 27, the screw engages with the nut and the shell with gyromotors is rotated by a certain angle. This makes it possible, when working with the device, to set the gyromotors in the necessary position to create a load on the muscles in a certain direction.
