Abstract:
1. Exercise equipment comprising: a stack of weight plates arranged from a topmost weight plate to a bottommost weight plate, each of said weight plates having a pair of guide rod openings for accommodating a respective guide rod therethrough, a pair of generally vertically-extending guide rods passing through respective guide rod openings of each weight plate in the stack, a user-selectable number of the weight plates being moveable along the guide rods in response to an exercise movement by a user of the equipment, a plurality of alignment members, each secured in a guide rod opening to provide a clearance fit around the guide rod passing therethrough, each shaped to mate with an adjacent alignment member of an adjacent plate in the stack to maintain alignment of the adjacent guide rod openings; and a keystone surface positioned below the stack to provide a precise setting of the stack's lateral position by mating with a mating surface carried by the bottommost weight plate, thereby aligning the aligned guide rod openings with the respective guide rod passing therethrough.
