  • Patent number: 6171221
    Abstract: A pair of extension bars join together in forming a tubular clamp having a raised wall surface, with the extension bars having angularly adjustable stirrups through which the arms of the user pass in grasping onto a pair of handle members, with one extension bar having a spring actuated finger pull to latch onto the raised wall in closing the tubular clamp in coupling to a weight bar, or in separating the tubular clamp when proceeding to couple to a different weight bar. The distance from the handle member to the clamp affords a lever action to increase resistance range without increasing any weight being exercised with, as well as working muscle at lower ranges of motion.

  • Patent number: 6092847
    Abstract: A set of locking tongs comprising a first arm and a second arm each comprising a hinge end and a grasping end. Hinge members are provided for pivotably connecting the first and second arms together at the hinge ends, so that the arms can pivot between an open position and closed position. Spring members are included for biasing the arms in an open position. The locking member comprises a captured pin attached to the first arm and an aperture member attached to the second arm. The captured pin has a pin that moves under the effects of gravity within a contained range of motion, limited by a bracket. The second arm has an aperture located on a surface. When the tongs are held in an attitude such that gravity can act upon the pin, the pin will engage the aperture and prevent the tongs from opening. The outward force applied by the spring acts to retain the pin in its locked position through frictional forces thus resisting opening.
