Abstract
In a weight raising exercise device a pair of upstanding lever assemblies, pivotally mounted on an open framework, are manually moved, alternately, toward one end of the frame in a push and pull action for raising and lowering framework guided weights selectively connected alternately with the respective lever assembly by chains entrained over sprockets and engaged with the weights by switch actuated solenoids. A fulcrum axle assembly, mounted on the framework between and pivotally connected with the lever assemblies, permits both lever assemblies to be used in raising and lowering the weights.
