HAND EXERCISER

摘要

FIELD: equipment simulating loading and used for training of arm wrestlers. SUBSTANCE: hand exerciser has frame, loader formed as electrically controlled magnetic dispersing brake with shaft and operating lever with handle. Horizontal support with hand thrust is mounted on frame in axial alignment with loader shaft, with thrust surface being coplanar with respect to shaft pin. Fork is rigidly fixed on shaft pin and provided with operating lever pivotally mounted on shaft pin for rotating in fork plane. Support with hand thrust is mounted on frame for repositioning and fixation along loader shaft pin. Loader is equipped with device for signalling extreme horizontal position of operating lever handle. Tube is mounted for free displacement along handle. Horizontal support with thrust is mounted on frame in cantilevered position. Control panel is mounted on frame. EFFECT: increased efficiency by imitating development of loading normally created during arm wrestling. 6 cl, 3 dwg
