摘要 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.
