Weightlifting apparatus
First Claim
1. A weightlifting apparatus comprising:
- a support frame having side sections defmiing a first direction and a handle adapted for grasping and lifting in a second direction different than the first direction;
a plurality of weights positioned between the side sections and having edges adjacent the side sections; and
an interlock mechanism including slide members slidably engaging and movable along the side sections, the slide members being configured to selectively engage and disengage the edges of the weights so that, when the handle is lifted, selected ones of the weights are secured to the support frame and lifted with the support frame.

Abstract
A weightlifting apparatus includes a ring-shaped support frame adapted to rest on a base that holds a plurality of weights, with side edges of the weights adjacent side sections of the support frame. An interlock mechanism includes slide members on the support frame that are movable along the side sections, and interlock tabs on the weights that slide across grooves in the weights. The slide members are configured to cammingly engage one end of the interlocking tabs, such that as the slide members engage the tabs on one side of the weights, the interlocking tabs move into engagement with an opposite side of the weights. The slide members are interconnected by a flexible ring, and are configured to move in opposite directions to selectively engage pairs of the weights so that pairs of the weights are selectively secured to the support frame by the interlock mechanism.

14. A weightlifting apparatus comprising:
-
a support frame having side sections defining a first direction and a handle adapted for grasping and lifting in a second direction different than the first direction;
a plurality of weights positioned between the side sections and having edges adjacent the side sections, each weight including an interlock tab member that is slidable toward the side sections and slidable away from the side sections; and
an interlock mechanism configured to selectively engage and disengage the interlock tab members with the side sections so that, when the handle is lifted, selected ones of the weights are secured to the support frame and lifted with the support frame and selected other ones of the weights are released from the support frame. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23)

24. A weightlifting apparatus comprising:
a weight plate including a mid-section defining a lateral direction, opposing edges and an interlock member slidably engaging the mid-section for movement parallel the lateral direction, the interlock member having a locking end and being moveable between a centered position where the locking end is located in an associated edge of the weight plate and an extended position where the locking end protrudes from the associated edge. - View Dependent Claims (25, 26)
