(54) TRAINING DEVICE

The invention relates to medical technology; namely, to devices for mechanotherapy. A training device is known, which is contained with guide grooves, avests, axles fixed on the frame, connected with a chain, while one of the sprockets has a drive of steps with wheels located on the guide grooves and associated with the TV chain. A disadvantage of the known device is that with the help of this device the subject performs monotonous movements and thus receives basically only physical activity without pronounced mental and emotional stress. In addition, the possibility of working out the coordination of movement and attention training when walking is not ensured, as this does not reduce the functional efficiency of the device. The purpose of the invention is to provide for the development of movement coordination and attention training when walking. The goal is achieved by the fact that a training device containing a frame with guide grooves, asterisks, v attached to the frame axles, is connected by a chain, with one of the asterisks driven, steps with wheels located on the guide grooves and connected with 11ep.yu, equipped with a turning mechanism, additional asterisks, connected with an additional chain, with fingers fixed at half of its length, with one and additional zapedokopochek connected to the drive with the help of belt furrows, a turning mechanism the company is made in the form of interconnected sprockets, gears and cams, as well as racks located on the sides of the studs, the steps are provided with rollers that are connected to the cams, while the sprockets of the turning mechanism of

They interact with additional chain fingers.

Fig 1 shows the kinematic scheme of the training device, side view; in fig. 2 - the same, top view; in fig. 3 - a fragment of the kinematic scheme with one step, front view; ka fig. 4 same, side view.

The device contains a set of stages 1 (Fig. 1) supported on cams 2 and 3 through rollers 4. Cams 2 and 3 are mounted on axis 5 freely, but fixed relative to them by means of brake clutch 6 (Fig. 2). The cams 2 are driven kinematically with the cam 3 of the gear train 7 whose figure (4). The cam 3 is rigidly connected to the drive sprocket 8 (Fig. 2). The axes 5 (fig. 1) of the cams are fixed on the supporting frame 9 supported on the guide grooves 1O by the wheels 11. The support system of step 1 includes a rod .12 (Fig. 3) with a ball joint .13i of the rack 14 with return springs 15 and restrictive fingers 16, rigidly fixed to the ends of the step 1. The wheels 11 (Fig. 1), installed in the guide grooves 10, are interconnected by drive chains 17, tensioned on the power sprockets 18. The drive also includes the electric motor 19 (Fig. 2, the variator 20 and the gearbox 21. Within the circuit of the drive chain is a generator 22 random effects (FGP), FGP consists of two identical chain drives 23 (Fig. 2), to which chains the driving fingers 24 are attached. Fingers 24 fill only half of the circuit of chain gears 23 (fg. 1). Belt drive 25 and the variator 26 (Fig. 2) serve to drive the GSB.In addition, a hole 27 is made in the supporting frame 9 and a slot 28 is in the cam 3. The sprockets 8, the gear train 7, the cams 2 and 3, are interconnected. as well as the rack 14, located on the sides of the stage 1, form a turning mechanism. The device works as follows. The movement from the electric motor 19 is transmitted through the variator 2O and the gearbox 21 to the power sprockets 18, which drive the drive chain 17 along with the set of stages 1 (Fig. 1). Simultaneously with chains 17, they begin to move with the help of a belt drive 25 chain drives 23 of the alternator 22 accidental influences.

transmission chains 23 must be several times lower than the speed of steps 1. When the drive sprocket 8 of each stage is engaged with the drive fingers

24, the sprocket 8 rotates through a certain angle, which depends on how many fingers are on the active branch of the chain transmission 23. As the chains move and the drive fingers 24 occupy only half of the contour of the transmission chain 23, the number of fingers on the active branch varies all the time . Therefore, the drive sprocket of each subsequent stage turns at a different angle. Evezdrchka causes the cams 2 and 3 to rotate, the height and angle of inclination of the stage depend on their position (Fig. 4). Thus, the difference in heights and angles of inclination of the subsequent steps, which determines the degree of mental influence on the subject, depends on the speed of the chains. This speed is governed by a variator 26 (Fig. 2). The position of the cams 2 and 3 after passing through the GSV 22 is fixed by the brake clutch 6 (Fig. 2) relative to the supporting frame 9. The position of stage 1 (Fig. 3) is determined by the presence of the rod 12, the return springs 15, the uprights 14 and the limiting fingers 16 A rod 12 moving with a change in the height of the step in the opening 27 of the carrier frame 9 prevents the ball joint 13 from moving in a horizontal plane. The fingers enter the slots of the pillars 14 and prevent the steps from rotating around the vertical axis. The springs 15 and the slot 28 in the cam 3 (FIG. 4) ensure the constant contact of the rollers 4 with the surfaces of the cams. Thus, the position of stage 1 in space is completely determined only by the angle of rotation and the shape of the profile of cams 2 and 3. Thus, when the device supports the stage, the complex spatial displacement relative to the initial position is reported and this area remains in a new position when it touches body of the test. Each time a person undergoes a movement, he moves to a supporting platform that differs in the inclination of the plane and the height of the step from the previous area, which causes the subject to increase attention and activate the muscular system by significantly transforming the body's sensorimotor program.

This is due to the fact that the subject, in addition to the physical exertion associated with lifting the step, receives a dose of mental effect in proportion to the degree of variation in the position of the steps. To enhance the effect of the mental effect, the steps have a contact surface with different coefficient of friction. The work of the subject under such conditions causes significant changes in the vegetative functions, which is reflected in the change in metabolism, hormonal and other indicators.

The design of the device ensures the development of movement coordination and attention training during hotsbe, which increases the efficiency of training.
