Abstract:
1. An adjustable weight kettlebell, comprising: a stack of weights, including an upper weight that defines a first opening, and a lower weight that defines a second opening, wherein the upper weight is configured to occupy a predetermined position on top of the lower weight with a protuberance on the lower weight projecting upward into the first opening; a weight lifting member configured to rest on top of the upper weight, wherein the weight lifting member includes (a) a handle connected to the weight lifting member, wherein the handle includes a hand grip configured and arranged for grasping in a person's hand at a location vertically above the stack when the weight lifting member is resting on top of the upper weight in the stack; (b) a weight engaging portion that registers with the upper weight; and (c) a weight selector having (i) a shaft that rotates about an axis relative to the weight engaging portion, and (ii) a weight retaining member rigidly connected to the shaft, wherein when the weight lifting member is resting on top of the upper weight, the weight retaining member occupies each said opening and is selectively rotatable into underlying engagement of each said weight; and when the weight selector occupies a first orientation relative to the weight engaging portion, the weight retaining member is free to move upward relative to each said weight, whereby the weight lifting member is liftable without any said weight; and when the weight selector occupies a second orientation relative to the weight engaging portion, the weight retaining member underlies only the upper weight, whereby the weight lifting member is liftable together with the upper weight; and when the weight selector occupies a third orientation relative to the weight engaging portion of the weight lifting member, the weight retaining member underlies at least the lower weight, whereby the weight lifting member is liftable with each said weight.
