Retaining device, particularly for training purposes

摘要

Training device for sprinters with a support (1b) which can be anchored securely in place and from which a rope (6b, 6c), possible to unite a user (18) can be drawn against a force retention over a distance of user training (18) to unwind the rope (6b, 6c) of a feed roller (4b, 4c), projecting axially feeding roller (4b, 4c) trunnions (39, 40) rotating in bearings (41, 42) in opposite directions, and with a brake device that generates the clamping force and frictional braking the unwinding of the rope feeding roller (4b, 4c) during the removal thereof, wherein bearings (41, 42) for the trunnions (39, 40) are arranged in opposite one another in a housing (2b, 2c) surrounding the feed roller (4b, 4c) and side walls (3c, 3c ') that the braking device comprises two brake discs (31, 32; 31c, 32c) coaxial with itself which can be tightened axially, the brake discs (31, 32 being arranged; 31c, 32c) coaxially with the feed roller (4b, 4c) or relative to a roller (24) arranged in front of the feed roller, with the rope (6b, 6c) disposed therearound, and rotatably mounted by trunnions (26, 27) and being connected one of the two brake discs (31, 31c) fixedly in rotation by the corresponding trunnion (31, 40) to the feed roller (6c) or the roller (24) in front and the other brake disc (32, 32c) being connected fixedly to the rotation to the housing (2b, 2c).
