ABSTRACT:
A tree stand for supporting a load, conventionally a person, above ground between a pair of spaced tree trunks or branches includes a pair of legs hinged together with spikes on the ends of the legs so that the stand may be positioned between the tree in the foreshortened condition and then forced to an elongated position to extend the spikes into the trees so that they support the stand.
