ABSTRACT:
A portable foldable hunting stand comprises a rigid U-shaped tubular platform and a rigid elongated tubular seat support member foldably connected thereto. The seat support member has a plate at one end with a wide angle V-notch, for abutting the surface of a vertically extending object on which it is to be mounted, and a padded seat rotatably mounted at the other end. A spike is selectively extendable from the platform to engage the surface of the object. A link chain secured at one end of the plate is looped around the vertically extending member and has its other end releasably received in a slot in the plate to attach the erected stand in a substantially horizontal position. A rope looped around the vertically extending object and releasably secured to each platform leg prevents disengagement and increases stability of the stand in the erected position. The rope provides a shoulder sling for carrying the stand in the collapsed transporting position. A T-bolt secures the stand in the folded and erected positions.
