ABSTRACT:
The present invention relates to a harness system for "climbing" tree stands to assist users in climbing, sitting in and descending trees. The invention has a standoff integrated with or attachable to the climbing tree stand for: (a) receiving a tree strap, (b) retaining a tree strap from inadvertent contact with the tree while the user climbs, sits in, and descends the tree, and (c) quickly releasing a tree strap from the climbing tree stand part.
The system also has a harness part. The harness part has (a) a thigh strap for bearing a user's weight about the user's thigh; (b) a waist strap for bearing a user's weight about the user's waist (the waist strap is attachable to the thigh strap); and (c) a tree strap for bearing a user's weight. The tree strap has a first end, a middle and a second end. The first end is attachable to the waist strap; the second end is passable around the trunk of the tree and slideably attachable to the middle of the tree strap; the middle is releasably attachable to the standoff.
If a user of the invention were to fall and exert adequate force on the tree strap, the standoff would release the middle of the tree strap, allowing the tree strap to become cinched around the tree. The user's weight could then be borne about the user's waist and thigh and supported by the tree.
