Abstract
A portable step assembly for attachment to a tree or pole includes a generally L-shaped climbing member and a separate, headed fastener member. The fastener member is removably insertable through a mounting portion on the climbing member after which the climbing member is employed as a crank tool to drive the fastener member into the tree. A specially configured socket recess or cavity within the mounting portion captively receives the screw member head and serves two primary purposes. First, it allows a one-handed push upon the assembly during the initial drive of the fastener member and secondly, dual sets of shoulders within the socket cavity form positive abutments to screw or unscrew the assembly respectively during its attachment or removal from a tree. By forming an end of the climbing member with a drive head mating with a segment of the mounting portion, the drive head of one climbing member may be coupled with the mounting portion of another climbing member being attached or removed from a tree, so as to provide additional leverage to facilitate application or removal of the fastener.
