ABSTRACT:
An exercising apparatus which comprises first and second sets of weights, each of which has an opening extending inwardly from a periphery thereof defined by opposed surfaces. An elongated tubular assembly is provided which has a longitudinal axis and includes exterior surfaces constructed and arranged to provide a central surface area configured to be manually engaged by a user and first and second surface areas on opposite sides of the central surface area configured to enter the openings of the first and second sets of weights into operative positions therein. The tubular assembly includes first and second sets of locking elements mounted within the first and second surface areas thereof for movement between weight releasing positions disposed within their respective first and second surface areas and weight locking positions extending partially outwardly of the respective first and second surface areas. The opposed surfaces of the weights have lock element receiving recesses therein. The tubular assembly also includes a weight selector member extending within the surface areas and mounted for movement about the longitudinal axis between a number of successive angular operative positions equal to the number of weights in each set. The weight selector member is interrelated to the locking elements such that when moved through the successive angular operative positions, the locking elements associated with successive weights of the first and second sets are moved into and retained in locking positions disposed within the lock receiving recesses. The arrangement is such that a selected number of weights of each set can be locked to the tubular assembly depending upon the operative position within the successive number of operative positions that the selector member is moved into.
