ABSTRACT:
An electro-mechanical weight lifting device is presented which allows a person to excercise by selecting a desired weight electronically. The present invention comprises a plurality of tension spring units (known as arbor mounted reels) on a frame. Preferably, eight tension spring units including four 50 pound, two 20 pound, one 10 pound and one 5 pound unit, are provided. Cables from the spring units are attached to a lifting arm which is pivotably mounted on the frame. The present invention further includes a digital key pad, digital display unit, selector solenoid unit, selectors, power supply and electronic logic. During operation, a weight is selected by activating the key pad whereupon the weight is displayed. The electronic logic then detects the key pad entry and energizes the selector solenoids which engage selectors for actuating a combination of tension springs. If a different weight is desired, a reset button on the key pad is used to disengage the selector units thereby allowing for a new combination of weights. An important feature of the present invention is the novel use of plurality of tension spring units. The tension spring units are small and compact, and provide certain advantages over the conventional use of actual metal weights in weight lifting machines.
