ABSTRACT:
A tree stand torso bar is attachable to a tree or post to support the torso of a hunter in a tree stand and prevent the hunter from accidentally falling out of the stand. The invention comprises a sturdy oval metal frame with vertical supports which engage the trunk of the tree, a lower cross-bar connecting the vertical supports, lower inclining struts which provide additional strength, and an adjustable strap which may be tightened by a ratchet mechanism to hold the device to the tree trunk or pole. The frame, supports, cross-bar, and struts are of integral, unitary construction. The device may be screwed into the tree by threaded stakes directed through apertures in the vertical supports. Alternatively, a second strap may be used in place of the threaded stakes.
