ABSTRACT:
A tree or the like climbing apparatus which includes a platform member, having both a seat portion and a foot support portion and an independent foot climber member. The platform member and the foot climber member are raised or lowered over a tree trunk by means of tree trunk engaging members on both the platform member and the foot climber member having parallel rows of teeth arranged in an arcuate manner. Opposite each engaging member is an adjustable cable support member to surround the tree trunk and provide a support means for engaging a portion of the tree trunk opposite the tree trunk engaging members. Rollers are positioned over each cable portion for part of its length to ensure smooth ascent and descent of the tree. Each cable portion includes an adjustable winch at one end, which secures the cable to the platform member and foot climber member, and also locks the platform member and foot climber member in place until further movement is desired.
