The device contains a base 1, the first 2 and second 3 racks installed on it, a dummy 4, a 5 m pneumatic actuator, a rotation drive 6, a compressed air source 7, a control unit 8, and a means of operational information about the onset of attacking actions.

The base 1 is made in the form of a trolley for movement in the horizontal plane. A first leg 2 is installed vertically on it, having a longitudinal slot 9. The dummy 4 is mounted in the slot 9 of the first leg 2 with the possibility of moving up and down along it with the help of rollers on the hinge axis (not shown). The dummy 4 contains the head 10, the body 11, interconnected motionless, and the multi-link lower and upper limbs. The lower limbs consist of links 12-14 connected in series with hinges. The upper limbs consist of successively connected ones with the help of hinges of links 15-17. At the same time adjacent links

innocence The actuator 6 moves the pneumatic damper 5 m cha and the dummy 4. Brush 17 moves forward - upward and simultaneously rotates forward around the axis of the hinge connecting it with s & 16. M at this flies out of brush 17 forward and upward. When the elbow joint of the upper limb of the dummy 4 is extended at a certain angle, an electrical signal is transmitted through the contacts of the sensor 42 to a time delay unit, which turns on the light bulb 44 after a set delay. 2 3.p. f-ly, 2 silt,

upper and lower limbs are set with the possibility of changing the angle between them in the vertical plane. Link 12 (thigh) and 15 (shoulder) are connected respectively to the lower and upper ends of the torso 11 of the dummy 4 with the possibility of changing the angle between the torso and thigh and torso and shoulder; the connections were made with the help of hinges. The second pole 3 is fixed fixedly parallel to the first pole 2 on the base 1 and has a matte (not shown), on which the vertical guide 18 is suspended,

having a longitudinal slot 19, in which with the help of rollers 20 and fastening strips 21 is mounted for movement along a guide 18 a circular guide (slide) 22,

having a notch 23. A 5 m pneumatic pneumatic actuator contains a pneumatic cylinder 24, inside which there are pneumatic chambers 25 formed by walls and a spring-loaded piston 26 with a pusher 27. Pneumatic chamber 25 has a manual exhaust valve (not shown) that connects pneumatic chamber 25 s the atmosphere. The outer end of the pusher 27 is pivotally connected (not shown) to the brush 17 of the upper extremity of the dummy 4. In addition to this point of attachment, the 5 m pneumatically actuator has three more points of attachment:

1) pneumatic cylinder 24 in the back

installed in the longitudinal slot 23 of the circular guide 22 with the possibility of movement along it and fixation with the help of a screw 28;

2) the front-bottom pneumatic cylinder 24 is hingedly attached (not shown) through a telescopic head 29 of adjustable length connected to it with a shoulder strap of the dummy A;

3) from above, the pneumatic cylinder 24 is fastened with the help of a flexible rod 30, retraction over the roller 31 mounted on the pneumatic cylinder 24, and through the rollers 32 and

33 mounted on a brace and fixed at one end on the upper part of the cylinder 24 through the drum 34 with a rotation handle 35 and lock clamp (not shown) and the other end on the drum 36 mounted on the shaft 37 of the rotational drive motor 6.

The rotational drive 6 is mounted stationary on the base 1 and consists of an electric motor, on the shaft 37 of which a drum 36 is installed for winding a flexible rod 30 equipped with a back brake-locking brake of the flexible rod 30. The brush, the distal link 17 of the dummy, is notched the cup-shaped form so that the mh embedded in it does not roll off spontaneously from it. All the described elements of the device, except for the dummy 4 can be made of metal. The dummy can be made of lightweight and durable plastics. The compressed air source 7 contains a chamber 38 with compressed air and an electrically controlled valve 39. The chamber 38 with compressed air through the valve 39 and the pipe 40 is pneumatically connected to the pneumatic chamber 25 of the pneumatic pulverizer 5 mph. The control unit 8 comprises in series a first power source (not shown) and a first adjustable unit (not shown) of the time delay of the electric signal by means of a knob 41, the output of which is the second output of the control unit 8 and connected to an electrical inlet of the pneumatic valve 39, and The power supply is the first output of the control unit 8 and is also connected to the control input of the actuator 6. In addition, the control unit contains serially connected angle sensors 42, a second power source (not shown) and a second p An adjustable block (not shown) of the time delay of the electric signal using knob 43.

The electric signal time delay unit is an additional output of control unit 8 and electrically connected to a signaling device (electric lamp) 44. The delay time is set manually using electric control knobs 41 (first adjustable electric signal time delay unit) and 43 (second adjustable electric signal time delay unit ). Using the control knob 41 of the first delay unit, set the delay time of switching on the electric pneumatic valve 39 (defining a shot of a pneumatic pusher 5 mph) with respect to the moment of switching on the electric motor of the drive 6 (determining the start of lifting the dummy up). Using the knob 43 controls the second delay unit to set the delay time of the light bulb 44 (signaling the beginning of the defender's response to the emission of a mannequin) with respect to the contact closing time in the sensor 42 of the angle at the elbow joint of the mannequin 4 (the moment of reaching a certain angle between the links 15 and 16 after, the beginning of extension of the dummy in the elbow joint). The mechanism of the ocerative information about the beginning of the attacking actions contains a sensor 42 of the angle at the elbow joint of the dummy 4 and a signaling device (electric bulb) 44. The angle sensor 42 can be made in the form of a limb fixed and coaxially fixed on the axis (not shown) of the hinge between adjacent links 15 and 16 of the upper limb of the dummy 4. Electric contacts are attached to the limb, which are connected via a power source and a second adjustable time delay unit of the electric signal to the electric light 44 installed on the link 16.

The device works as follows.

1. The movable base 1 with the device fixed on it is installed in the place of the site that corresponds to the beginning of the attack.

2. Install the required height of the distal link 17 of the upper extremity of the dummy 4. In this step, into the brake, use the rotary knob 35 to rotate the drum 34 mounted on the upper part of the pneumatic chuck 24, reducing or

By increasing the length of the flexible rod 30 and, respectively, simultaneously lowering or raising the pneumatic pusher 5 m and dummy 4, connected between themselves with the help of a telescopic rod 29 and a pusher 27, the height of the distal link 17 is changed depending on the height of the players.

3. Set the desired departure angle. To do this, release the screw.

28, the rear part of the pneumatic cylinder 24 is moved up or down along the slot 23 of the circular guide 22, respectively, reducing or increasing the angle of inclination of the pneumatic tappet 5 meters to the ground plane 1. The same angle can be reduced or increased by changing the angles between adjacent links 15 and 16 and 16 and 17 of the upper limb of the dummy 4, due to the corresponding decrease or increase in the length of the telescopic rod

29. For this, removing the lock, reduce or increase the length of the rod 29 by pushing or pushing the upper component of the rod 29, and then again fix its length firmly with a lock. The ability to change the angle of departure of the ball allows you to simulate different techniques for throwing the ball along the ejection path. And the possibility of changing the angle between the adjacent links of the upper limb of the dummy makes it possible to imitate various techniques of throws of the ball, determined, among other things, by different degrees of flexion in the joints of the arm in the starting position for the throw.

4. Insert the mh into the brush 17 of the dummy 4.

5. Use the control knob 41 of the control unit 8 to set the required delay time T of switching on the electric pneumatic valve 39 in relation to the moment of switching on the electric drive of the actuator 6.

6. Use the control knob 43 of the control unit 8 to set the required delay time Tj of the signal lamp 44 with respect to the closing time of the electrical contacts in the angle sensor 42 between adjacent links 15 and 16 of the upper limb of the dummy 4.

Thus, the mannequin is ready to throw the ball.

7. Sportsman takes place at a certain distance in front of the dummy and is ready to respond to the throw.

8. The trainer presses the start button (not shown), including the first power source and, consequently, the electric drive motor 6. Bending the cable 30, winding on the drum 36 mounted on the shaft 37 of the drive motor 6, lifts the pneumotouch valve 5 simultaneously The meter and the dummy 4, interconnected by a telescopic rod 29 and a pusher 27. After a set time T, the delays are supplied from the first source to the second output of the unit 8, the electric valve 39 and the air from chamber 38 are opened source of compressed air of the spirit 7 through the pipeline 40 rushes into the pneumatic chamber 25 of the pneumatic puller 5, presses its piston 26 and the pusher 27 connected with it, the jogging movement of which forward causes a sharp extension of the upper limb of the dummy 4. At the same time, the distal link 17 moves forward-up and simultaneously rotates forward around an axis pivotally connecting it with link 16. Due to this, the ball lying on distal link 17 flies forward and upward from it. The change in the magnitude of the first delay T allows you to imitate the throws from the spot (pneumatic pusher 5 operates when the dummy 4 has distal links 14 of the lower limb not yet detached from the floor; only extension goes under its own weight in the joints of the lower limb of the dummy when lifting it ), and jumps in a jump (pneumatic pusher 5 is triggered later when mannequin 2 has already broken off from the support).

The extension of the upper limb of the dummy 4 occurs simultaneously in the ray (connection of links 16 and 17), and in the elbow (connection of links 15 and 16) joints. When the upper limb of the dummy 4 is extended at the elbow joint at a certain angle (determined by the position of the contacts B to the limb), electrical contacts in the angle sensor 42 are closed, and the electrical signal from the second power source is transmitted through the angle sensor 42 contacts to the second adjustable time delay unit (not shown), which, after a set delay T, turns on the warning light 44 mounted on link 16. The athlete jumps up, reacting to the ignition of the light bulb 71331517

44, and alters the flight trajectory a (covers mh).

The second delay T allows you to differentiate for the time of recovery when covering the ball while changing the distance from the defender to the defender, who drops the ball: the greater the distance, the later after the start of the match

The extensor arm movement should be responsive.

9. After the train leaves the dummy 17 of the dummy 4, the trainer releases the start button (not shown), disconnecting the first power source and drive electric motor 6. The dummy 4 stops and freezes by fixing the flexible rod 30 with the reverse brake on the drum 36. Simultaneously with the termination of the electrical signal, the valve 3 closes the course of the compressed air in the pneumatic pusher 5, stopping the action of the pusher 27 on the distal link 17 of the upper limb of the dummy 4.

10. By releasing air from the pneumatic chamber 24 of the pneumatic separator 5 through an exhaust valve connected to the atmosphere, the trainer sets the required angles between the adjacent links of the upper limb of the dummy 4 for a second throw.

11. Gradually release the reverse brake of the flexible rod 30 in the drum 37, the trainer sets the required height of the distal link 17 of the upper limb of the dummy 4 for a second throw and puts the m h into the brush 17 of the dummy 4.

The device is ready for the next shot.

The advantage of the proposed device in comparison with the known one is that it allows, by providing imitation, attacking actions of the player with a ball under conditions close to real, work out the protective actions of the basketball player, namely covering the ball, years on the desired trajectory.
