Abstract
An elevated hunting stand with a platform assembly and a collapsible ladder. The collapsible ladder includes a plurality of telescopically separating sections. The ladder sections are secured together by locking pins. The ladder rails and rungs are pivotally attached and operated as a parallelogram linkage system, so the ladder sections can be reduced in size to a compressed configuration by rotating the rungs relative to the rails. A plurality of stabilizing members are provided to hold the ladder sections in an expanded position. The platform assembly can serve as one of the stabilizing members.
