Abstract
A weight lifting device includes a frame having a weight stack secured to the frame, a force applicator secured to the frame and connected to the weight stack by a hydraulic connector, so that a person, who applies a muscular force to the force applicator, activates the hydraulic connector moves the weight stack and exercises the muscles. The weight stack is connected through a hydraulic system to a force applicator which includes a fluid contained cylinder that has a reciprocating piston that is acted upon by a user to cause fluid to act on and lift a plurality of stacked weight.
Claims7
A weight lifting device comprising a frame, said frame having secured thereto, a variable weight stack, a force applicator means for moving said variable weight stack, a connecting means for operably connecting said force applicator means to said variable weight stack so that movement of said force applicator means causes movement of a selected portion of said variable stack, wherein:
- (a) said force applicator means is acted upon by a user during exercise of one or more groups of muscles;
- (b) said variable weight stack includes a first weight and a second weight, said second weight adjustable and removable attachable to said first weight, said first weight is operably and directly connected to said connecting means:
- (c) a hydraulic connector forming a part of the connecting means and comprises a hydraulic cylinder operatively connected to said weight stack;
- and
- (d) said connecting means including a hydraulic connecting means being connected at one end to said variable weight stack and at the other end to said force applicator means to thereby form a closed hydraulic circuit.
