Abstract
Abstract A tree-climbing platform has a stand portion of rigid sheet material and a pair of tubular runners secured to either side of the stand spaced thereabove. The tree-contacting end of the stand has a V-notch at the center and projecting teeth formed in plates secured to the stand along the sides of the notch. The runners project beyond this end and a crossbar having a toothed plate secured to the center thereof is adjustably and removably secured at each end to the runners. Stirrups for the feet of the climber are secured to the stand adjacent the V-notch and a seat of fabric belting looped around the runners is provided above the stirrups. Back-pack straps are removably secured to the under side of the stand and pads are provided for being secured looped around the toothed plates at the V-notch when the platform is backpacked. A hand climber accessory for the platform comprises a tubular handle and a rope adapted to be secured to one end of the handle, then passed around a tree and wound in several turns around the other end of the handle.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
215 words
A tree-climbing platform comprising a substantially rectangular stand portion of rigid sheet material having a V-notch at one end, a tubular runner at either side of the platform, the main portions of each runner being secured to the stand parallel to and spaced thereabove, the stand having a metal plate secured thereto along each side of the V-notch, each plate having teeth along one edge projecting beyond the stand for engagement with a tree trunk, the stand having stirrups secured thereto adjacent the V-notch adapted for engagement with the feet of a climber, each runner projecting beyond the V-notched end of the stand and adapted to extend on either side of a tree trunk to be climbed, a crossbar removably secured at each end to a runner, the crossbar having a metal plate secured thereto at its center, the crossbar plate having teeth along one edge projecting from the crossbar and adapted to contact the tree trunk on the side opposite that contacted by the V-notch plates teeth, whereby a climber may embrace a tree with his arms while bending his knees to raise the platform and then put his weight on the platform to reengage the platform with the tree and thereafter grasp the tree at a higher level for again raising the platform.
Claim 2
Dependent Claim
215 words
A tree-climbing platform comprising a substantially rectangular stand portion of rigid sheet material having a V-notch at one end, a tubular runner at either side of the platform, the main portions of each runner being secured to the stand parallel to and spaced thereabove, the stand having a metal plate secured thereto along each side of the V-notch, each plate having teeth along one edge projecting beyond the stand for engagement with a tree trunk, the stand having stirrups secured thereto adjacent the V-notch adapted for engagement with the feet of a climber, each runner projecting beyond the V-notched end of the stand and adapted to extend on either side of a tree trunk to be climbed, a crossbar removably secured at each end to a runner, the crossbar having a metal plate secured thereto at its center, the crossbar plate having teeth along one edge projecting from the crossbar and adapted to contact the tree trunk on the side opposite that contacted by the V-notch plates teeth, whereby a climber may embrace a tree with his arms while bending his knees to raise the platform and then put his weight on the platform to reengage the platform with the tree and thereafter grasp the tree at a higher level for again raising the platform.
Claim 3
Dependent Claim
54 words
The platform defined in claim 1 wherein the runners project beyond the V-notched end of the stand a distance sufficient to allow the crossbar to be secured to the runners at a distance whereby the distance between the V-notch plates teeth and the crossbar plate teeth spans a tree trunk 18 inches in diameter.
Claim 4
Dependent Claim
43 words
The platform defined in claim 1 wherein the V-notch plates teeth and the crossbar plate teeth are formed by arcuate, vertically extending notches cut at evenly spaced intervals to intersect and form at their intersection sharp pointed teeth at least one-fourth inch long.
Claim 5
Dependent Claim
52 words
The platform defined in claim 1 wherein the tubular runners are curved at one end toward the stand and secured thereto at the end opposite the V-notched end of the stand, whereby the platform may be inverted with the runners down to form a sled for carrying game shot from the platform.
Claim 6
Dependent Claim
44 words
The platform defined in claim 1 wherein the surface of the stand opposite the surface to which the stirrups are attached has a pair of back-pack straps removably secured thereto, whereby the platform may be back-packed, the projecting ends of the runners projecting upward.
Claim 7
Dependent Claim
125 words
In combination with the platform defined in claim 1, a hand-climber accessory comprising: a tubular handle at least equal in length to the diameter of the tree to be climbed, and a rope, one end of the rope being knotted around the handle adjacent one end, the rope being adapted to be passed around a tree to be climbed, and the rope being wound around the other end of the handle in a plurality of turns, whereby a climber grasps the handle adjacent the knot with one hand, wraps the rope around the tree and around the other end of the handle and grasps the handle with the other hand around the turns and pulls himself upward with his arms when climbing with the platform.
Claim 8
Dependent Claim
35 words
The platform defined in claim 3 wherein the teeth of the crossbar carried plate are arranged arcuately, the radius of the arc being at least substantially half the diameter of the tree to be climbed.
Claim 9
Dependent Claim
31 words
The platform defined in claim 5 wherein the V-notch plates have thick pads of textile material wrapped therearound covering the teeth, the ends of the pads being secured to the stand.
