<p>PCT No. PCT/SE92/00068 Sec. 371 Date Aug. 4, 1993 Sec. 102(e) Date Aug. 4, 1993 PCT Filed Feb. 6, 1991 PCT Pub. No. WO92/13603 PCT Pub. Date Aug. 20, 1992.Exercising device comprising a moving unit (1-6'), a motion-transferring mechanism (7, 10-11') connected to the moving unit, and a hydraulic system (8-9, 12-17) connected to said motion transferring mechanism for controlling the motions of the moving unit. The invention is characterized in that the moving unit comprises a substantially vertically movable, tubular rod (1) with an integrated mounting (2, 2') at each end, and two separate, flexible and elongate elements (4, 4'). Each element is fixedly attached to a stationary fastening means (5, 5', 6, 6') above and, respectively, below the rod (1). Moreover, each element is arranged to extend through the tubular rod between the associated upper and, respectively, lower fastening means. The motion-transferring mechanism comprises at least one flexible, elongate member (7, 7') which is fixedly attached to one mounting (2) of the movable rod and to the through piston rod (8) of a piston cylinder (9) included in the hydraulic system. In addition to the piston cylinder, the hydraulic system comprises a control circuit (15-17) connected to the piston cylinder.</p> |
