ABSTRACT:
An automatic hunter's prop is adapted for quickly lifting a hunter lying on his back in a camouflage position to a ready position for shooting game. The hunter's prop includes a base frame for being positioned on a ground surface, and a launching frame connected to the base frame. The launching frame is pivotable between a tension-loaded condition wherein the launching frame extends generally parallel to the base frame, and a tension-released condition wherein the launching frame extends upwardly at an angle to the base frame. A pair of coiled springs increase tension in the launching frame when moved from the tension-released condition to the tension-loaded condition. A releasible catch and hook cooperate to releasibly set the launching frame in the tension-loaded condition. A trigger cord releases the catch from the hook and rapidly pivots the launching frame upwardly into the tension-released condition. The hunter lying on the prop is quickly lifted upwardly by the launching frame from the camouflage position to the ready position for shooting game.
