Abstract

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.

Dependent claims

An exercising device, comprising:

a tubular rod;
first and second mounting fixedly coupled to opposite ends of said rod;
first and second flexible elongated elements, each of said elongated elements having top and bottom ends, said first and second elongated elements extending oppositely through said tubular rod so that said top ends of said elongated elements extend from opposite ends of said tubular rod;
fastening means for attaching said top ends of said elongated elements to a support and for attaching said bottom ends of said elongated elements to the support, said bottom ends being below said top ends so that said tubular rod is movable in a generally vertical direction;
at least one flexible elongated member having first and second ends, said first end of said elongated member being attached to one of said mountings;
hydraulic means for providing a resistive force, said hydraulic means including a piston cylinder attached to said second end of said elongated member thereby providing a resistive force to movement of said tubular rod;
and
a control circuit for controlling the resistive force provided by said hydraulic means.
