ABSTRACT:
A tree stand includes a pin up system for easy attachment and removal to a tree high above the ground. The tree stand includes a frame and a platform attached to the frame for supporting the weight of a user and equipment. A hanger stud having a rectangular cross section projects from the frame towards the ground. The tree stand is attached to the tree trunk with a hanger pin which includes a shank with a pointed screw tip at one end for penetrating into the tree trunk. A crank is attached to the shank for rotating the shank and facilitating penetration of the screw tip and shank into the tree trunk. A stud holder is attached to the shank and has an aperture with the same rectangular cross-sectional shape as the hanger stud and is adapted to receive the hanger stud in the aperture to securely hold the frame on the tree trunk. In addition, an automotive seat belt is attached to the frame of the tree stand and is wrapped around the tree trunk to more securely hold the tree stand to the trunk. A pair of projections extend from the frame towards the tree trunk provide added frictional contact and in conjunction with the seat belt and the pin up system to firmly and safely support the tree stand on the tree trunk.
