Abstract
Abstract The screw at the upper end of the bracket leg is screwed into a tree to support the bracket with the step extending horizontally. When detached the screw can be folded into the leg and moved to a position preventing pivoting the screw relative to the leg. The bracket can now be folded. The screw can also be positioned to extend axially from the leg while unable to pivot with respect to the bracket so the folded bracket serves as a handle for the screw.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
198 words
A device to be affixed to a tree comprising an L-shaped bracket having an upstanding support leg member and a horizontal step member and a screw pivotally connected to the upper end of the leg member to attach the bracket to a tree or the like, the improvement comprising, said screw being pivotally connected to the leg member for movement through about 270° from an inactive position in which the screw is parallel to the leg member and points toward said step member to an extended position in which it is generally parallel to and points away from the leg member and then to an active position in which it projects from the leg member at about 90°, said step member being connected to the leg member for limited pivotal movement between a position in which the members are generally at about 90° to each other and a folded position in which the members are parallel, means preventing pivotal movement of the screw relative to the leg member when the members are in said folded position, said screw lying between the members when the screw is in its inactive position and the members are in said folded position.
Claim 2
Independent Claim
198 words
A device to be affixed to a tree comprising an L-shaped bracket having an upstanding support leg member and a horizontal step member and a screw pivotally connected to the upper end of the leg member to attach the bracket to a tree or the like, the improvement comprising, said screw being pivotally connected to the leg member for movement through about 270° from an inactive position in which the screw is parallel to the leg member and points toward said step member to an extended position in which it is generally parallel to and points away from the leg member and then to an active position in which it projects from the leg member at about 90°, said step member being connected to the leg member for limited pivotal movement between a position in which the members are generally at about 90° to each other and a folded position in which the members are parallel, means preventing pivotal movement of the screw relative to the leg member when the members are in said folded position, said screw lying between the members when the screw is in its inactive position and the members are in said folded position.
Claim 3
Dependent Claim
33 words
A device according to claim 1 in which the leg member has a U-shaped cross section and the screw is received inside the leg member when the screw is in said inactive position.
Claim 4
Dependent Claim
50 words
A device according to claim 2 in which the screw is connected to the leg member by means permitting movement of the screw longitudinally of the leg member between a first position in which the screw cannot pivot and a second position in which the screw is free to pivot.
Claim 5
Dependent Claim
32 words
A device according to claim 3 in which the step member has a U-shaped cross section and one member is received inside the other when the members are in said folded position.
Claim 6
Dependent Claim
24 words
A device according to claim 4 including means preventing pivoting the members to said folded position when the screw is in said second position.
Claim 7
Dependent Claim
56 words
A device according to claim 5 in which the means connecting the screw to the leg member comprises a pivot pin transverse the screw and engaging the sides of the leg member, and including a cut-out in each side of the step member to fit over and receive the pivot pin when the bracket is folded.
Claim 8
Dependent Claim
36 words
A device according to claim 6 in which the means connecting the screw to the leg member for limited longitudinal movement comprises longitudinally disposed slots in the sides of the leg member receiving the pivot pin.
Claim 9
Dependent Claim
38 words
A device according to claim 7 in which the means preventing movement of the members to said folded position when the screw is in said second position comprise the sides of said step member striking the pivot pin.
Claim 10
Dependent Claim
53 words
A device according to claim 8 in which the sides of the upper end of the U-shaped leg member extend beyond the U-shaped leg member and the slots extend into the extended sides so the pivot pin and screw can be pivoted without interference from the U-shaped cross section of the leg member.
Claim 11
Independent Claim
166 words
A device to be affixed to a tree comprising an L-shaped bracket having an upstanding support leg member and a horizontal step member and a screw pivotally connected to the upper end of the leg member to attach the bracket to a tree or the like, the improvement comprising, said step member being connected to the leg member for limited pivotal movement between an operative position in which the members are generally at about 90° to each other and a folded position in which the members are parallel, said screw being pivotally and slidably connected to the leg member for movement from an inactive position in which the screw is parallel to the leg member and points toward said step member to an extended position in which it is generally parallel to and points away from the leg member and has an active position in which it projects from the leg member at about 90° in a direction opposite the operative position of the step member.
Claim 12
Independent Claim
166 words
A device to be affixed to a tree comprising an L-shaped bracket having an upstanding support leg member and a horizontal step member and a screw pivotally connected to the upper end of the leg member to attach the bracket to a tree or the like, the improvement comprising, said step member being connected to the leg member for limited pivotal movement between an operative position in which the members are generally at about 90° to each other and a folded position in which the members are parallel, said screw being pivotally and slidably connected to the leg member for movement from an inactive position in which the screw is parallel to the leg member and points toward said step member to an extended position in which it is generally parallel to and points away from the leg member and has an active position in which it projects from the leg member at about 90° in a direction opposite the operative position of the step member.
Claim 13
Dependent Claim
30 words
A device according to claim 10 in which said screw lies between the members when the screw is in its inactive position and the members are in said folded position.
