Abstract
At least one supplemental weight is selectively movable into and out of the path traversed by the top plate in a weight stack. The supplemental weight(s) may be configured to register with the top plate, provided with handle(s), and/or added to existing weight stack equipment.
Claims23
A method of adjusting resistance on an exercise apparatus of the type having a stack of weights movably mounted on a frame, including a top plate which is movable along a path, comprising the steps of:
- providing a frame including at least one guide rod;
- movably mounting the stack of weights on the at least one guide rod in such a manner that the top plate in the stack is movable along a path;
- routing a flexible member between the top plate and an upper portion of the frame;
- constraining a supplemental weight to move along at least one of the flexible member and the at least one guide rod;
- providing a support on the frame to support the supplemental weight in an inactive position above and beyond the path of the top plate;
- and
- requiring a user to move at least a portion of the supplemental weight in a direction transverse to the at least one guide rod in order to free the supplemental weight from the support for downward movement into an active position within the path of the top plate.
A method of adjusting resistance on an exercise apparatus of the type having a stack of weights movably mounted on a frame, comprising the steps of:
- providing a frame with first and second guide rods;
- movably mounting a stack of weights on both said guide rods in such a manner that a top plate in the stack is movable along a path;
- movably mounting a supplemental weight on both said guide rods;
- providing a support on the frame to support the supplemental weight in an inactive position above and beyond the path of the top plate;
- and
- requiring a user to move at least a portion of the supplemental weight transversely relative to the guide rods in order to free the supplemental weight from the support for downward movement into an active position within the path of the top plate.
An exercise apparatus, comprising:
- a frame;
- a stack of weights movably mounted on the frame, wherein the stack includes a top plate which is movable along a path;
- a supplemental weight;
- and
- a handle connected to the supplemental weight to facilitate maneuvering of the supplemental weight into and out of the path of the top plate;
- wherein the frame defines an interior space bounded on at least one side by a shield with the supplemental weight constrained in the interior space and the handle on the opposite side of the shield from the supplemental weight.
