Device useful in windsurfing or other sports for training loops, comprises cylindrical wheel, unit for positioning foot of training person on inner side of circumference of wheel, and unit for supporting wheel about its rotational axis

摘要

The device comprises a walk-hollow cylindrical wheel (2), a unit (30) for positioning foot of a training person on an inner side of a circumference (12) of the wheel, and a rotatable unit (18, 19, 20, 21) for supporting the wheel about its rotational axis. The supporting unit is a supporting frame. The wheel has a cylindrical grid frame (3), and two parallel tires and crossbars that extend itself over a distance area between the two tires. The wheel at the two end faces comprises a wheel hub or shaft that is connected with a tire via spokes. The device comprises a walk-hollow cylindrical wheel (2), a unit (30) for positioning foot of a training person on an inner side of a circumference (12) of the wheel, and a rotatable unit (18, 19, 20, 21) for supporting the wheel about its rotational axis. The supporting unit is a supporting frame. The wheel has a cylindrical grid frame (3), and two parallel tires and crossbars that extend itself over a distance area between the two tires. The wheel at the two end faces comprises a wheel hub or shaft that is connected with a tire via spokes. The spokes are externally inclined to a plane through the tire. The wheel hub or shaft is arranged at a distance from the plane by the tires. The positioning unit comprises: a surfboard; a unit for releasably holding the foot; a unit for holding the surfboard at the inner side of the circumference of the wheel; a mast; a fork boom; and a rig. The mast, the fork boom and the rig are positioned with respect to the wheel. The holding unit has holding loops and/or clamping devices. A hinge is arranged between the board and the wheel. The holding unit of the foot is arranged at the surfboard. A mast foot is fixed at the surfboard or the wheel and/or the holding unit of a mast's top is arranged into the wheel. The fork boom is fixed at a front side of the mast and/or is fixed at a back side of the wheel. The supporting unit is positioned at the bottom of a base, and has a servo motor and an upper supporting unit that supports the hub of the wheel. The device further comprises a unit for generating an air flow entering into the wheel, and a sensor for detecting a rotational position of the wheel and/or a camera for detecting movements of the training person arranged in the wheel. The sensor and/or the chamber of an input device is connected with an electronic data processing apparatus. The generating unit comprises a blower and/or an air guiding device. An electronic data processing device is configured so that it steers a flow of program dependent on the rotational position of the wheel and/or the movements of the training person. The servo motor is connected with an electronic data processing system that is formed in such a way that it controls a predetermined movement of the wheel.
