ABSTRACT:
A tree step (20) comprises a first member (24) which has a second member (30) pivotally connected thereto. Connected to the first member (24) is a braided rope (28) which substantially encircles a tree when the tree step (20) is in an installed configuration. The second member (30) includes a foot-support portion (60) which has a spacer portion (62) integral therewith at a proximal end thereof. The spacer portion (62) serves to space a pivot point (82) from foot-supporting surfaces (72, 74) to a sufficient extent that, when the second member (30) has the braided rope (28) wound therearound, and when the second member (30) is pivoted to a storage configuration, the braided rope (28) is securely engaged between the foot-supporting surfaces (72, 74) and the first member (24). The spacer portion (62) has stabilization flanges (96, 98) extending rearwardly therefrom, the backsides of which provide stabilization surfaces (100, 102) which contact the tree when the tree step (20) is in an installed configuration. Rounded corners (104, 106) are provided on the flanges (96, 98) to facilitate snug engagement of the tree step (20) about the tree. The second member (30) is locked securely in its installed configuration with respect to the first member (24) by virtue of tapering sidewalls (66, 68) and a shoulder (94) provided on the second member (30).
