Abstract
An exercise machine has multiple stations at each of which two or more exercises are performed in opposition to a selected amount of weight in a weight stack. A cable and pulley system connects the exercise apparatus at the exercise stations with the weight stack in such a manner that only one pull cable in the system is connected to the weight stack.
Claims11
An exercise machine having an exercise station comprising:
- a pedestal;
- a back rest and a seat mounted on said pedestal;
- a pair of handles at opposite sides of said seat and arranged to swing forwardly to an upright active position from a retracted position;
- a dual-purpose unit of generally inverted T-shape swingably hanging adjacent the front of said seat for forward swinging movement from a lowered position;
- locking means for selectively locking said handles in their said active position and said dual-purpose unit in its said lowered position;
- a load;
- an exercise element positioned adjacent the top of said back rest;
- a cable and pulley system connected to said load and including a first cable end located adjacent the top of said back rest and connected to said exercise element, and including a second cable end connected to said dual-purpose unit, whereby pulling on said exercise element is yieldingly resisted by said load via said first cable and whereby forward swinging movement of the dual-purpose unit is yieldingly resisted by said load via said second cable when said dual-purpose unit is not locked.
5 more elements
A yoke assembly for connecting to a cable having a terminal ball and located on an exercise machine, said yoke assembly comprising:
- a flexible padded yoke element;
- a central fitting with a keyhole slot having an eye portion for receiving such a ball of a size to pass through said eye portion and not through the remainder of said slot, said central fitting also having a second slot;
- a pair of handle grips remote from said fitting;
- and
- a strap passing through said second slot and connected along a major part of its length to said padded yoke element, said strap having a pair of loops at its opposite ends which interfit with said handle grips.
