Patent ID: 8394004

Claim:
A selectorized dumbbell, which comprises: (a) an array of nested weights comprising a stack of nested left weight plates and a stack of nested right weight plates; (b) a handle having a left end and a right end with the handle ends extending substantially perpendicularly relative to a hand grip of the handle and with the handle ends also being disposed substantially parallel to the weight plates; and (c) a selector for coupling selected numbers of left weight plates to the left end of the handle and selected numbers of right weight plates to the right end of the handle, wherein the selector comprises a plurality of connecting pins on each of the left and right ends of the handle, wherein the connecting pins are vertically spaced apart from one another in each of the handle ends in a vertically spread apart pin array and are horizontally movable between a weight coupling position in which the connecting pins are extended outwardly relative to the handle ends and a weight uncoupling position in which the connecting pins are retracted inwardly relative to the handle ends, and wherein the connecting pins move in a direction that is substantially perpendicular relative to the hand grip and substantially parallel relative to the handle ends as the connecting pins move back and forth between their weight coupling and weight uncoupling positions.
