Abstract
A collapsible plant support is provided having a plurality of elongated wire-rod legs which are rigidly secured together at one end. Several helically-wound wire springs of normally elongated configuration are also provided with each spring having the opposite ends adapted to be interconnected and thus form circular rings. These rings are positioned at vertically spaced elevations on the legs which are relatively divergent from their connected ends when the plant support is positioned upright on the ground. Each of the elongated legs is formed with longitudinally spaced notches into which the circularly configured wire springs are positioned and supported on the divergent legs having their free end portions inserted into the ground. Collapsing of the plant support for storage is readily accomplished by first pulling the legs from the ground thereby releasing the rings. The rings are then disconnected at their ends whereupon they again assume the relaxed, elongated configuration. The helical wire springs have an internal diameter to permit the springs to be threaded onto respective ones of the elongated legs in retained relationship for purposes of storage.
