ABSTRACT:
A tree climbing stand is made of two assemblies, the seat assembly and the platform assembly. Each has folding support arms which support a V-bar gripper. The V-bar gripper is made of hollow aluminum to maximize strength and reduce weight. Each V-bar gripper has a pair of clutch mechanisms in a housing assembly. The clutch mechanisms use cams to precisely adjust the grip on the tree and do it silently. The housing assemblies also serve to lock the entire unit together in a backpack mode.
