Abstract: A hunter's tree stand (10) comprising a planar seat member (16) of generally rectilinear form having a pair of opposed generally V-shaped notches (18, 19) formed in its opposite ends which are adapted to engage and partially surround, in intimate face-to-face relation, the facing portions of a pair of diverging tree branches (14, 15) at the fork (11) formed thereby, a sharp, laterally projecting V-shaped metal knife-like edge (20) secured to the undersurface of the seat member (16) in juxtaposition to and projecting laterally from the first V-shaped notch (18), and an L-shaped bracket (22) releasably secured to the undersurface of the seat member (16) by means of one or more bolt and nut combinations (29, 31) for permitting lateral extension of said L-shaped bracket (22) relative to the second of the V-shaped notches (19) to permit the depending bracket leg (25) to be placed in face-to-face contact with the other of the diverging branches (14) and positively secured thereto by one or more threaded fasteners (26 ) extending therethrough. The hunter's tree stand (10) may optionally be provided with a soft cushion (36) to render the stand more comfortable in use and/or with a safety line (32) which can be tied off to one of the diverging tree branches.
