ABSTRACT:
A removable tree stand with a novel shur lok latch. A platform extends laterally outward from the tree in a nominally horizontal position. The platform end proximal to the tree includes a mechanism for engaging the tree. Integral tubular support arms project up at an angle from both sides of the platform to a height above the platform. A support cable, including a plurality of mechanical stops, encircles the tree trunk and is inserted through both tubular support arms. The first key feature is a novel pivoting cable engagement mechanism, called a shur lock latch, on each support arm that is easily engaged and provides a positive lock that prohibits inadvertent disengagement of the support cable in both the loaded and unloaded condition. A second key feature is that the support cable is powdercoated to provide increased durability.
