ABSTRACT:
A super stable, simply assembleable tree stand is provided for artificial Christmas trees and the like, which stand provides increased stability in relation to the load applied. The stand includes a central, disc-shaped hub portion which interlocks vertically and horizontally with a plurality of radiating, tapered legs, with the component parts so configured that, when interlocked, they cannot be separated under load, or loosen or "wobble" with respect to each other. The component parts are comprised of substantially rigid thermoplastic resin material with a slight degree of resiliency, such as high impact polystyrene, so as to provide a gripping action between the parts when they are joined. The legs are connected to the hub portion with a tongue and groove arrangement connectable from the bottom of the stand upwardly, so that applied loads from above serve to urge the tongue and groove joints into a fully seated and totally stable condition.
