Abstract
Abstract A tree step having an integral angle bracket with an obtuse angle forming a foot-supporting portion and a projecting tree-engaging leg with a projecting supporting arm connected pivotally and lockably to the angle bracket intermediate its ends with the free end of the projecting supporting arm having a tree-securing means thereon at the free end. The free end of the projecting tree-engaging leg of the angle bracket forms the hypotenuse of a right triangle when the tree step supporting arm is secured to a tree trunk with the tree trunk and the projecting tree-engaging leg forming the legs of a right triangle. The foot-supporting portion of the bracket projects outwardly from the supporting arm and upwardly from the tree-engaging leg.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
113 words
A tree step comprising; an integral angle bracket having a foot-supporting portion and a projecting leg portion, said projecting leg portion having a tree-engaging end portion, a projecting supporting arm having opposite ends, one of said ends being secured to said angle bracket intermediate its ends, and the other said end being free, said other free end having a tree-engaging securing means thereon for supporting said integral angle bracket whereby upon retaining the projecting supporting arm in a horizontal position in a tree, said foot-supporting portion is substantially horizontal and said projecting leg portion forms a hypotenuse of a right triangle upon tree engagement by said tree-engaging end portion of said supporting arm.
Claim 2
Dependent Claim
113 words
A tree step comprising; an integral angle bracket having a foot-supporting portion and a projecting leg portion, said projecting leg portion having a tree-engaging end portion, a projecting supporting arm having opposite ends, one of said ends being secured to said angle bracket intermediate its ends, and the other said end being free, said other free end having a tree-engaging securing means thereon for supporting said integral angle bracket whereby upon retaining the projecting supporting arm in a horizontal position in a tree, said foot-supporting portion is substantially horizontal and said projecting leg portion forms a hypotenuse of a right triangle upon tree engagement by said tree-engaging end portion of said supporting arm.
Claim 3
Dependent Claim
18 words
A tree step as claimed in claim 1, said tree-engaging securing means being pivotally secured to said bracket.
Claim 4
Dependent Claim
56 words
A tree step as claimed in claim 1, said integral angle bracket being a channel member having a U-shaped cross-section with a base web, said foot-supporting portion and said projecting leg portion forming an obtuse angle therebetween, said projecting supporting arm being pivotally secured in said channel member adjacent to the apex of said obtuse angle.
Claim 5
Dependent Claim
23 words
A tree step as claimed in claim 1, said tree-engaging securing means including a conically-tapered helical screw for penetration into a tree trunk.
Claim 6
Dependent Claim
36 words
A tree step as claimed in claim 3, said projecting supporting arm having a free end extending beyond said one secured end to engage said base web in a position for rotation of said supporting arm.
Claim 7
Dependent Claim
31 words
A tree step as claimed in claim 5, and said tree-engaging securing means including a conically-tapered helical screw for threading penetration into a tree trunk upon rotation of said channel member.
