Abstract
Aspects of the present invention relate to a weight stack including a weight selector mechanism providing an adjustable source of resistance for use with a variety of load bearing exercise devices. The weight stack can include a plurality of weight plates stacked one on top of another. The weight selection mechanism can include a weight selector member extending through and adapted to selectively connect with each weight plate. The weight selector member can include a plurality of projections adapted to selectively engage engagement surfaces in the weight plates. A user can rotate the weight selector member with a selector knob to connect the desired number of weights to be lifted with the weight selector member. Embodiments of the weight stack can also include a locking mechanism that prevent a user from turning the weight selector member once a sufficient lifting force is applied to the selected weight plates.
