Abstract
Abstract The tree stand comprises a platform having a metal support strap encircling the tree with the tree received in a diverging notch in the platform. The sides of the outer portion of the notch are convex and the sides of the inner portion of the notch are concave to permit a wide range of tree diameters to be engaged by the notch. All tree sizes in the range are contacted at widely spaced points and smaller trees are gripped by the notch. The notch is lined with a ribbed rubber facing and the strap is rubber covered where it contacts the tree.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
236 words
A tree stand comprising, a platform having a notch therein adapted to bear against a tree trunk of 6" diameter or more at points well spaced from an extension of the centerline of the platform and notch, a metal support strap which is flexible along its length to enable it to embrace the tree trunk and which is adjustably connected to the platform so the platform is generally horizontal in use, said notch engaging one side of a tree and the strap engaging the other side of the tree at a vertically elevated location so weight on the platform tends to drive the platform against the tree trunk and tilting the outer or front portion of the platform upwardly acts to disengage the tree stand from the tree the notch has sides which diverge from the root of the notch, the sides of the root portion of the notch being concave and leading to outer convex portions, the concave and convex curves being selected so a small diameter tree engages the sides close to the root of the notch and progressively larger trees contact the sides progressively further from the root, an elastomer facing on the tree engaging surface of the notch, an elastomer facing on the tree engaging surface of the strap, said elastomer facings acting to grip the tree to mount the platform on the tree without sliding and without damage to the tree.

Dependent Claim
47 words
A tree stand according to claim 1 in which trees 6" in diameter and greater are engaged by the notch at points about 90° apart relative to the center of the tree to retain the platform on the tree without slipping and without damage to the tree.
