Abstract
Abstract A tree step including a steel rod bent into a configuration including an elongated central portion and a pair of perpendicularly oriented right triangular shaped portions extending perpendicularly from the central portion with one leg of each right triangular shaped portion being at opposite ends of the central portion and lying in parallel planes forming a pair of spaced apart 90 degree orientated steps.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
127 words
A tree step comprising: an elongated steel rod bent into a pair of right triangular shaped portions meeting at a vertex of each right triangular shaped portion, said right triangular shaped portions lying in perpendicular planes with one leg of each right triangular shaped portion that forms the right angle of each respective right triangular shaped portion lying on a line of intersection between the planes of the two triangular shaped portions, a second leg of each right triangular shaped portion that forms the right angle of each respective right triangular shaped portion lying in parallel spaced apart planes perpendicular to the planes of the pair of right triangular shaped portions; and rope means for securing said one leg of said right triangular portions to the tree.
Claim 2
Dependent Claim
127 words
A tree step comprising: an elongated steel rod bent into a pair of right triangular shaped portions meeting at a vertex of each right triangular shaped portion, said right triangular shaped portions lying in perpendicular planes with one leg of each right triangular shaped portion that forms the right angle of each respective right triangular shaped portion lying on a line of intersection between the planes of the two triangular shaped portions, a second leg of each right triangular shaped portion that forms the right angle of each respective right triangular shaped portion lying in parallel spaced apart planes perpendicular to the planes of the pair of right triangular shaped portions; and rope means for securing said one leg of said right triangular portions to the tree.
Claim 3
Dependent Claim
21 words
The tree step as defined in claim 1 further including means for supporting said device against a trunk of the tree.
Claim 4
Dependent Claim
40 words
The tree step as defined in claim 2 wherein said means for supporting includes two support members at spaced apart locations along the length of said one legs of said triangular shaped portions adapted to engage against said tree trunk.
Claim 5
Dependent Claim
27 words
The tree step as defined in claim 3 wherein each of said support members comprises a pair of protrusions diverging outwardly from each of said spaced locations.
Claim 6
Dependent Claim
60 words
A tree step comprising: a steel rod bent into a configuration including an elongated straight central portion and a pair of right triangular shaped portions extending from said central portion in perpendicular planes, said central portion lying on an line of intersection between said perpendicular planes; and rope means for securing said central portion to a trunk of the tree.
Claim 7
Dependent Claim
60 words
A tree step comprising: a steel rod bent into a configuration including an elongated straight central portion and a pair of right triangular shaped portions extending from said central portion in perpendicular planes, said central portion lying on an line of intersection between said perpendicular planes; and rope means for securing said central portion to a trunk of the tree.
Claim 8
Dependent Claim
23 words
The tree step as defined in claim 5 further including a pair of support members at spaced apart locations along said central portion.
Claim 9
Dependent Claim
24 words
The tree step as defined in claim 6 wherein each support member comprises a pair of co-planer diverging protrusions extending from said central portion.
Claim 10
Dependent Claim
24 words
The tree step as defined in claim 7 wherein each support member comprises an angular shaped length of rod affixed to each central portion.
Claim 11
Dependent Claim
103 words
A tree step comprising: a one piece continuous rod-like member bent into a configuration including an elongated central portion, a first step portion extending perpendicularly from said central portion at one end of the central portion and a second step portion extending perpendicularly from said central portion at an end of said central portion opposite said one end and being perpendicular to said first step portion; support means on said central portion for engaging against a trunk portion of the tree; and means adapted to encircle said trunk portion of the tree to hold said tree support means tightly against said trunk portion.
Claim 12
Dependent Claim
103 words
A tree step comprising: a one piece continuous rod-like member bent into a configuration including an elongated central portion, a first step portion extending perpendicularly from said central portion at one end of the central portion and a second step portion extending perpendicularly from said central portion at an end of said central portion opposite said one end and being perpendicular to said first step portion; support means on said central portion for engaging against a trunk portion of the tree; and means adapted to encircle said trunk portion of the tree to hold said tree support means tightly against said trunk portion.
