ABSTRACT:
A new observation and hunting stand with safety platform for preventing accidental falls from such stands, particularly tripod supported stands. The inventive device includes a tripod support base supported by the ground, and a platform attached to an upper end of the tripod support base. The platform includes a pivoting door formed therein which pivots between open and closed positions to permit ingress into, and egress from, the platform. In the closed position of the door, the platform is substantially solid with no openings therein, to prevent falls from the platform. The door is trapezoidal in shape with a wide end thereof adjacent the edge of the platform to allow passage of a person. In the open position of the door, the door rests against a seat support post, thus defining a stop for the door.
