ABSTRACT:
A sportman's ladder for allowing convenient climbing of trees and the like includes upper and lower sections assembled together in telescoping relationship. Each section has secured thereto a plurality of spaced-apart steps extending laterally from opposite sides thereof in an alternating manner. The upper section includes a tree limb engaging hook formed as a square, cornered structure having angled gussets at the corners thereof for structural bracing and for improved modes of engagement on the tree limb. The upper section also has a pair of cleats which receive and mount the lower section to the upper section in stacked relationship with respect thereto for convenient carrying of the upper and lower sections when unassembled.
