Patent ID: 7850581

Claim:
A selectorized dumbbell, which comprises: (a) a plurality of nested weights that provide a stack of nested left weight plates and a stack of nested right weight plates that are separated by a gap; (b) an elongated handle extending along an axis with the handle having opposite left and right ends and with the handle being dropped into the gap between the weight plate stacks; (c) a selector that couples a selected number of the left weight plates to the left end of the handle in a nested side by side manner extending along the axis and that couples a selected number of the right weight plates to the right end of the handle in a nested side by side manner extending along the axis; (d) a first flexible and resilient shock absorbing system provided in the nested weights, wherein the first shock absorbing system is configured to support the weight plates in a normal, substantially upright orientation relative to the axis of the handle and to allow the weight plates in response to a shock to pivot or tilt sideways relative to the axis of the handle out of their normal orientation and into a deflected orientation, the first shock absorbing system further providing a biasing force on the weight plates when the weight plates are in their deflected orientation which biasing force restores the weight plates back into their normal orientation after the shock dissipates and the weight plates are free to move back to their normal orientation; and (e) a second flexible and resilient shock absorbing system that is separate and distinct from the first flexible and resilient shock absorbing system with the second shock absorbing system being provided in the selector.
