Description

The invention relates to sports simulators and can be used to train players when practicing blows in game ice hockey.

State of the art

A known simulator for mastering the hockey technique (RF patent 2382664, published on 01/10/2009), containing a base, a goal and a disk horizontally rotatable from the drive, additional discs are built into the surface of the disc with the possibility of rotation at different speeds and different directions relative to the main disk and each other.

The disadvantage of this simulator is that the translational movement of the washer occurs only due to the adhesion of the lower supporting surface of the washer to the surface of rotation, which limits the range of variation of the speed and force of impact on the washer. In addition, the installation is cumbersome with a large number of drive mechanisms, which does not ensure its mobility.

Known washer of the brand PUCCO (http://www.paramecanic.se/), including a housing, a power unit with an electric motor, a drive unit, a washer supply unit, an impact unit. Giving speed to the washer is due to centrifugal force when the washer leaves the groove of the disk rotating at the outlet of the washer supply unit. The disadvantage of this device is that the change in the direction of departure of the puck is made by the operator manually by moving the entire body of the device. In addition, the installation can only be used to train hockey team goalkeepers.

The closest in technical essence and the achieved technical result is a device used to train the game of hockey with the puck (US patent 7166045, IPC А63В 69/00, date publ. 23.01.2007), including a drive unit with an electric motor, gearbox, gear with two pulleys connected by a belt, as well as including a washer supply unit made in the form of an inclined groove, next to which a rotating disk is installed to control the frequency of supply of washers. The speed control of the washer throw is carried out by two accelerator rollers located symmetrically at the exit in the lower part of the inclined trough. The rotation of the accelerator rollers is carried out by placing them on the same axis with belt pulleys. When leaving the inclined trough with a frequency determined by the speed of rotation of the rotating disk near the trough, the washer passes between the accelerator rollers, while the speed of the washer outflow is determined by the speed of their rotation.

The disadvantage of this device is that the installation is stationary and the washers are thrown in one direction without changing the angle of attack, which reduces the effectiveness of training athletes.

Disclosure of invention

The objective of the proposed device is to create real conditions for practicing blows on the puck when training players in hockey with the puck and training goalkeepers to repel blows, as well as increasing the efficiency of using training time in preparing athletes for playing hockey.

The technical result achieved by the present invention is to expand the range of variation of the characteristics of the movement of the pucks provided during the training of players in hockey, in particular, the change in speed and angle of the puck.

The technical result, which consists in the possibility of changing the speed of the throw of the puck, is achieved due to the fact that the automatic puck feeding device for training the game of hockey includes a movable frame with a tabletop connected by spring shock absorbers, as well as a puck supply pipe, a shock unit and a knot for changing the angle of the puck out, wherein the shock unit includes a firing pin made in the form of a flat rectangular plate and a rectangular block rigidly connected to each other, mounted on a countertop, with a pr of the pit bar block by the shock spring block and vibration damper, as well as a replaceable lever of the shock block, made, for example, in the form of an eccentric and mounted on the axis of the gearbox shaft connected to the electric motor, while the electric motor is mounted on screw-shaped shafts using nut connections, and the support of helical-shaped shafts rigidly connected to the countertop.

The technical result, which consists in the possibility of changing the angle of the throw of the pucks, is achieved by the fact that the device for automatically feeding the puck for training the game includes a block for changing the direction of the puck out, made in the form of a prefabricated bracket with a three-way magnetic valve and an electric motor, while the bracket is made of a fixed part, rigidly connected to the surface of the countertop, and a movable part connected to a three-way valve, driven by an electric motor.

Brief Description of the Drawings

In FIG. 1 is a diagram of an automatic puck feeder for training a hockey game (top view), FIG. 2 is a device, side view, FIG. 3 - feed pipe and block change direction washers.

The implementation of the invention

An automatic puck feeder for training a hockey game includes a rectangular frame 1 made of a metal profile (corner) having the ability to change the installation location (movement); a rectangular metal tabletop 2 with a partial PTFE coating, connected to the rectangular frame 1 by spring shock absorbers 3; the shock block, including the striker 4, made in the form of a flat rectangular plate 5 and a rectangular bar 6 rigidly connected to each other with a shock spring unit 7 and a pneumatic vibration damper 8. The shock block also includes a replaceable lever 9, made in the form of an eccentric and mounted on the axis of the shaft of the gearbox 10 connected to the motor 11 with a frequency converter. In order to change the frequency of impact on the washer 15, the interchangeable lever 9 can be made three-pointed (options) or with a different number of petals. The electric motor 11 is mounted on helical shafts 12 by means of nut connections 13. Helical shafts 12 are rigidly connected to the horizontal surface of the countertop 2.

The mobile puck automatic device for training a hockey game also includes a puck supply pipe 14 located at right angles to the surface of the countertop 2 and connected to the puck throw angle changing unit. The unit for changing the angle of the washer 15 is made in the form of a pre-assembled bracket 16 (Fig. 3) connected to a three-way magnetic valve and an electric motor 17. The pre-assembled bracket 16 is made of a fixed annular part 18, rigidly fixed to the surface of the tabletop 2 on two protrusions along the central axis of the striker 4 of the shock unit, and the movable ring part 19, mounted concentrically on the outer side surface of the stationary ring part 18. The movable ring part 19, connected to the electric motor 17, is made in its upper part in the form of cylines pa, and at the bottom - on the one hand to a bracket 20 situated diametrically thereto a rectangular recess 21.

The work of the mobile device for the automatic supply of pucks for training a game of hockey is as follows. Frame 1 with a worktop 2 and equipment installed on it is installed at the venue for training for playing hockey. The electric motor 11 connected to the electric network, through the gearbox, transmits torque to it and drives the interchangeable lever 9 of the shock unit through the shaft of the gearbox 10. When rotating, the interchangeable lever 9 engages with the end face of the bar 6 of the striker 4 of the shock unit, giving it linear movement. Shifting in the direction of rotation of the shift lever 9, the opposite end of the bar 6 and the end of the rectangular plate 5 compress the shock spring unit 7. The compression ratio of the springs 7, which determines the force of impact on the washer 15, and as a result, the speed of the washer 15, is determined by the distance A between the end of the bar 6 and the central axis of the shaft of the gearbox 10, on which the interchangeable lever 10 is mounted, as well as the length of the interchangeable lever 9. The distance A is controlled by linear movement of the electric motor 11 with the gearbox shaft 10 using nut connections 13 along the shafts 12.

After the contact lever 9 and the end face of the bar 4 come out of contact, the end face of a flat rectangular plate 5 of the striker 4, sliding along the fluoroplastic part of the countertop 2, impacts the washer 15 fed through the pipe 14 due to the return movement with energy generated by compression of the springs 7 into a rectangular recess 21 of the pre-assembled bracket 16 and placed on the path of the striker 4. The washer 15, having received acceleration from the striker 4, is guided along the path defined by the petals of the bracket 20 of the movable ring part 19. The rotation angle of the movable bracket 20 and the angle yleta washer 15 controlled three-way magnetic valve driven by a motor 17.

To give mobility, the device can be equipped with wheels. The weight of the training device is about 40-45 kg.
