Patent ID: 7771330

Claim:
A selectorized dumbbell, which comprises: (a) a plurality of nested weights, a handle, and a selector that couples a selected number of the weights to the handle; and (b) wherein each nested weight comprises: (i) at least one rigid weight plate; and (ii) a weight frame with rigid and flexible portions, wherein the flexible portion of each weight frame comprises a substantially planar flexible arm that bends or flexes at a location adjacent one end of the arm, wherein the weight plate is immovably attached to and carried by an opposite free end of the flexible arm of the weight frame such that the flexible arm substantially alone bears and supports the weight of the weight plate and the flexible arm and the weight plate jointly move together as one unit to permit the weight plate to move relative to the rigid portion of the weight frame in response to an impact shock by flexing of the flexible arm relative to the rigid portion of the weight frame.
