Claim 1
Independent Claim
228 words
An exercise device which can be used to perform a plurality of different exercises comprising first and second spaced upright ladder members each having lower ends for supporting said exercise device and upper ends and each of said ladder members including a pair of elongated rails and a plurality of parallel spaced cross bars extending transversely between said rails; a grip-bar assembly extending between said first and second ladder members and attached to said upper ends thereof, said grip-bar assembly including a pair of elongated rails and a plurality of spaced grip bars extending between said rails, said plurality of grip bars being arranged in first and second groups adjacent said first and second ladder members, respectively, and each of said grip bars extends transverse to said rails of said grip-bar assembly, and said grip-bar assembly further including a plurality of longitudinal bars extending between said first and second groups of grip bars in parallel with said rails of said grip-bar assembly; and an elongated bed-shelf assembly extending between said first and second ladder members including a base having first and second ends, said first and second ends of said base including slot means for engaging said cross bars of said first and second ladder assemblies to support said bed-shelf assembly in a position transverse to said ladder members and in positions angularly displaced from said transverse position.
Claim 2
Dependent Claim
