EXERCISER FOR CANOE SPORTSMEN

摘要

sportive equipment. SUBSTANCE: exerciser has frame with seat and feet rest, loader and oar simulating device connected to loader. Longitudinal bars are pivotally mounted on ends of oar simulating device. Mid and end portions of bars are connected through first and second parallel crank slide mechanisms made in the form of horizontal shafts with cranks fixed on shaft ends and turned through 180 deg one with respect to another. Cranks of first shaft are equipped with slides mounted on middle portion of bars for displacement along them. Cranks of second shaft are connected to bars through pivot joint. Both crankshafts are coupled through engagement transmission to loader formed as adjustable electric drive. First shaft is mounted in bearings fixed on frame. Cranks of first shaft are put onto shaft by inserting into grooves for displacement along shaft and are spring-loaded relative to bearing. Follower is rigidly mounted on crank end at side adjacent to bearing. Follower working surface is engaged with roller stop rigidly fixed to frame. Cranks of shafts are mounted for repositioning relative to bars. Seat and feet rest are arranged on frame for repositioning along frame. Torque coupling is mounted on electric drive shaft. Roller stop is fixed to frame for repositioning relative to longitudinal axis of first shaft. EFFECT: increased efficiency and simplified construction. 6 cl, 2 dwg
