ABSTRACT:
The deck of a tree climbing platform is mounted upon a suitable frame including opposed generally parallel side members. A frame member is disposed on each side of the deck and extends angularly upwardly and rearwardly relative to the deck. A U-shaped foot member having generally parallel side legs connected by a foot rung member is disposed with a side leg to each side of the deck and extends angularly downwardly and forwardly relative to the deck. Transversely spaced and axially aligned pivot connections are provided in the opposed deck side members adjacent to the forward end of the deck for pivotally mounting the corresponding frame member and distal end of the foot member side leg to each side of the deck. The angularly disposed frame members extend beyond the rear of the deck and pivotally mount a linkage member intermediate their length. A second linkage member is pivotally mounted to each of the side legs of the U-shaped foot member. The distal ends of the linkage member and second linkage member on each side of the deck being secured by a common fastener to the corresponding deck side member adjacent to the rear of the deck to render the tree climbing platform operable.
