Selectorized dumbbell having an upper selector and weights formed by laterally spaced weight plates joined by thin connecting walls

Abstract

A selectorized dumbbell has a plurality of nested weights which each have a box-shaped configuration comprising spaced left and right weight plates joined by planar, substantially imperforate, front and rear walls. The front and rear walls of the nested weights are very thin in comparison to the weight plates, extend over substantially the full height of the weight plates, and are joined to the weight plates along substantially their entire height. A selector comprises a pair of connecting members that coact between a handle of the dumbbell and upper portions of the front and rear walls of the nested weights to select a desired number of the weights for use with the handle depending upon the selected positions of the connecting members.
