ABSTRACT:
A Christmas tree stand comprises a bowl, a support collar mounted over the bowl that bears a set of angularly spaced threaded nuts, and a set of turn screws threaded through the support collar nuts. A set of arcuate clamping plates is positioned in a cylindrical formation within the support collar. Each plate has a channel in which an end of one of the turn screws is rotatably captured. With this construction, threaded advancement of the turn screws may cause the arcuate clamping plates to tighten convergently upon a tree trunk positioned within the support collar without the arcuate plates rotating substantially out of their cylindrical formation.
