Abstract:
1. An adjustable dumbbell assembly of the type including two sets of weights, each weight including a radial opening extending from a central area to a peripheral area and at least one transversely extending opening in the central area communicating with said radial opening, and a weight supporting assembly operable to selectively connect and disconnect the two sets of weights thereto on opposite sides of a handle, said weight supporting assembly on each side including a fixed weight entering structure, movable weight selector structure, and manually turnable actuating structure, said fixed weight entering structure being configured and positioned to enter radially within the radial openings of said weights and into an operative position with respect thereto, said movable weight selector structure being configured and positioned to enter axially in one direction into the at least one transverse opening of selected weights when said fixed structure is in the operative position thereof with respect to the weights and to withdraw axially in an opposite direction out of the at least one transverse opening of selected weights when the fixed structure is in an operative position with respect to the weights, said manually turnable actuating structure being positioned such that one of the two sets of weights is between the handle and the manually tumable actuating structure, said manually turnable actuating structure being configured to be manually grasped at the end of the side and turned in opposite directions about an axially extending turning axis coincident with a longitudinal axis of the handle, wherein when said fixed structure is in an operative position with respect to said weights, manually turning said actuating structure in one direction moves the selector structure in said one direction and manually turning said actuating structure in an opposite direction moves the selector structure in said opposite direction.
