Description

The invention relates to the technical means of training hockey athletes with a puck and is intended to enhance the skills of hockey players when they master the puck after throwing it.

The purpose of the invention is to increase the effectiveness of the training to master the puck after it has been thrown by the judge in the zone of the throw-in under conditions of a simulated game situation of the opponent’s counter action against the stick.

FIG. 1 shows a block diagram of the device; in fig. 2 is a view A of FIG. one; in FIG. 3, view B in FIG. one,

The device consists of a cylindrical storage unit 1, a round cover 2. closing the lower opening of the storage unit -power, electric motor 3, which through its shaft 4 is connected to the gearbox 5, power supply units 6, time relay 7, reverse unit 8, club 9, coupling 10, first springs 11. frame 12, bracket 13, second springs

14, an electromagnet consisting of core 15 and obmbtki 16. The gearbox has an output shaft 17.

The drive 1 placed washers 18 (40-50 pieces).

The device works as follows

After filling the cylindrical storage ring 1 with washers, 18 km of bringing the entire circuit into a working state (switching on the power supply unit 6). Time relay 7, reverse unit 8, a training hockey player is located next to drive 1, so that his club (athlete) is under the lower end of the receiver accumulator in the drop zone of the ice washer and in the movement zone of the stick 9 of the device. The goal of the hockey player training is to capture the puck that falls out of the accumulator 1 while the stick 9 of the device interfering with disturbances interferes with the rotational-translational motion in the zone of the puck falling. At the same time, the control of the moments of fall of shyO x |

s

from accumulator 1 would be as follows.

Using the switch (regulator) of the time of operation of the time relay 7, the operator sets the required time interval and the repetition frequency of the operation of this relay. When the time relay 7 is triggered, a current flows through the winding 16 of the electromagnet, and the core 15 of the electromagnet, retracted inside it, moves, stretching the spring 14. while the round cover 2, connected mechanically to the core 15, also moves, opening the lower hole of the cylindrical storage 1. As a result of this, the puck from the accumulator of the feeder is down due to its strength of gravity and falls into the zone in which the club 9 of the device and the athlete's club are located. Then time relay 7 opens its contact, as a result, the winding 16 of the electromagnet de-energizes. As a consequence, the core 15 together with the round cap 2, due to the extended springs 14, return to the initial state. At the same time, the round cover 2 again closes the lower opening of the accumulator 1, preventing other washers from falling out until the next time relay 7 triggers, as a result of which the cycle is repeated in a similar manner periodically until all the washers are out of the accumulator. After this, drive 1 is charged with a new batch of washers.

The movement control of the club 9 of the device is carried out as follows. The supply voltage from unit 6 is supplied through the unit, the reverse 8 to the field winding of the electric motor 3, as a result of which its shaft 4 will come into rotation.

At that, the reverse unit 8 with a predetermined frequency (for example, from 1 to 5 switches per second) commutes the polarity of the supply voltage on the excitation winding of the electric motor 3, as a result of which the direction of rotation of the electric motor shaft 4 periodically changes and, consequently, the direction displacement connected to it via gear 5 and

its shaft 17 stickleys 9 devices. So

In this way, the programmed control of the movement of the club 9 of the device (in frequency and amplitude), which creates a programmable interfering effect on the stick trained at the throw-in of the puck (simulating the actions of an opponent), is carried out in a manner.
