Description

The invention relates to sports equipment, in particular to devices for the preparation of swimmers.

A device is known (Pat. PCT PACER FOR ATHLETES No. WO 2008/022356 Al (M. Cl A63B 69/12, A63B 69/00, E04H 4/14, H05B 37/02, international publication date 02.21.08, analogue) containing many light-emitting elements located on the bottom of the pool, controlled by a programmable controller.The controller, taking into account the entered data, turns on the light-emitting elements one by one, the athlete follows the luminous element passes the distance according to the entered parameters.

The disadvantages of this device are: difficult installation and dismantling of light-emitting elements, the creation of interference by the simulator when servicing the bottom of the pool.

A device is known (Pat. CZ No. 13276 U1, M. Cl. G07C 1/00, G07C 1/22, publ. 05/05/2003, prototype) containing two laser emitters installed in a stadium with a treadmill, the leading element in in the form of a point of incidence of a laser beam on a special surface. The movement of the leading element is carried out by means of an electric motor and a mechanism that changes the angle of incidence of the laser beam on a special surface. The motor is controlled by a programmable panel. This known device is the closest to the proposed device and is selected as a prototype.

The disadvantages of this device are: low accuracy at small angles of incidence of the beam, the movement of the leading element (laser point) only in the straight sections of the stadium.

The objective of the proposed technical solution is to eliminate the noted drawbacks, namely: increasing accuracy at small angles of incidence of the beam, organizing the possibility of movement of the leading element in curved sections of the path of the athlete, simplifying installation and dismantling, eliminating interference during maintenance of the bottom of the swimming pool.

To solve this problem, a device is proposed comprising a laser emitter with an electric motor drive, according to the invention, a rotary disk is additionally included, on which reflecting mirrors are placed, mounted at an angle to the laser beam, connected to an electric motor drive, the laser emitter is positioned so that the laser beam is incident on mirrors mounted on a rotating disk, the number of mirrors on the disk is set based on the step of moving the laser beam, the parameters of a sports facility I and the speed of the distance, the angles of the mirrors are calculated based on the parameters of a sports facility.

A significant difference is that a rotating disk is additionally included, on which reflecting mirrors are placed, mounted at an angle to the laser beam, the laser emitter connected to the electromotor drive is positioned so that the laser beam hits the mirrors mounted on the rotating disk, the number of mirrors on the disk set based on the step of moving the laser beam, the parameters of a sports facility and the speed of the distance, the angles of installation of the mirrors are calculated based on the parameters of the spores ivnogo structure, variation of the angle of incidence of the laser beam is performed by rotation of the disk, which has reflecting mirrors to predetermined angles of the laser beam deflection.

Using a rotating disk with mirrors allows you to set the angles of incidence of the laser beam both small and large with high accuracy, the ability to set the mirror at many angles in two planes will allow the leading element (laser point) to move along a straight line and along a curved path.

Figure 1 presents the functional diagram of the device of a laser simulator for training athletes, where the following notation is introduced: a rotating disk 1 on which mirrors 2 are mounted, a laser radiation source 3, a laser beam 4, an electric motor 5, a control device 6, an angle α between water surface and laser beam 4.

Figure 2 shows the installation option of a laser simulator for training athletes in a swimming pool, where: a laser beam 4, a control device 6, an angle α between the water surface and a laser beam 4, Y is the height of the laser simulator from the bottom of the pool, X is the distance from the installation point of the simulator, at the bottom, to the leading element.

Reflecting mirrors 2 are mounted on the rotating disk 1. The rotating disk 1 is connected to an electric motor drive 5 connected to the control device 6. The laser emitter 3 emits a laser beam 4 and is mounted so that the laser beam 4 is incident on the reflecting mirror and is reflected from it at an angle α relative to the surface of the water.

The simulator works as follows. For example, the simulator is installed at the bottom of the swimming pool so that through the point of location of the laser simulator and any point on the bottom of the track of the swimming pool, you can draw a straight line, see figure 2 (it is possible to use the laser simulator in other sports facilities such as treadmills, bicycle paths and etc.). The location of the laser simulator is at a height Y from the bottom of the swimming pool, see figure 2. In the control device 6, before the start of the exercise, parameters are set, for example, the duration of the distance, the time taken to go the distance or the speed of the distance, acceleration. Then carry out the launch of the control device 6.

The control device 6, taking into account the entered parameters, sends a signal to the electric motor drive 5, which rotates the disk 1, thereby bringing each mirror in turn to the laser beam 4 emitted by the device 3. The mirrors 2 are installed so that the laser beam 4, reflected from the mirror, falls to the bottom of the pool at an angle α relative to the surface of the water, thereby organizing a leading element (laser point) at the bottom of the pool at the point of incidence of the laser beam. The angle α is calculated based on the parameters of a sports facility, for example, for a swimming pool in which the bottom on a shallow part is parallel to the water surface, for organizing a leading element (laser point) on a shallow part of the pool at a distance X from the installation point of the simulator at the bottom of the pool, angle α (X) is calculated by the expression:

α (X) = 90-arctg (X / Y)

where Y is the installation height of the laser simulator from the bottom of the pool (constant value), see figure 2. For other sections of swimming pools and for sports facilities of a different profile, the formulas for calculating the angle α are complicated, the complexity of the calculation depends on the parameters of the structures.

When the disk rotates, the mirrors change, the angle α changes and the laser beam 4 and the leading element (the laser point at the bottom) move along the swimming path according to the specified parameters, in the control device 6, along the bottom of the pool. The athlete follows the leading element (a laser dot at the bottom of the pool), not lagging behind and not surpassing it, thereby passing the distance in accordance with the established parameters in the device 6.

For example, to train a swimmer in a swimming pool 25 m long, a distance of 50 m and a travel time of 30 seconds are set. The disk contains 100 mirrors, that is, when 25 meters are passed, 100 points will appear alternately at the bottom, the step of the leading element will be 25 cm. The electronic control device 6 is started. The electronic control device calculates the rotation speed of the disk using the parameters entered earlier and supplies voltage to the electric drive 5 such that the disk makes one revolution in 15 seconds in one direction and the second revolution in 15 seconds in the opposite direction. The laser point, having passed along the bottom of the pool 25 meters, will change the direction of movement to the opposite and, having passed the second 25 meters in the opposite direction, will stop. The athlete will move behind the laser point at the bottom of the pool and swim 50 meters in 30 seconds.

The device does not contain elements difficult to manufacture and can be easily implemented.

The implementation of the proposed device will allow you to master the mathematically calculated load on the athlete’s body, contributes to the training of the athlete in the distribution of physical forces over long distances. Allows you to change the load during the exercise. The device is compact, there is the possibility of easy transportation and quick installation of the device, for example, when leaving for sports camps.
