Abstract
Abstract A tree climbing platform embodying a base plate having side members projecting beyond an end thereof and disposed to extend alongside opposite sides of a tree with said one end of the base plate spaced from the adjacent side of the tree and the other end thereof extending away from the tree. A first blade carried by the side members bites into the opposite side of the tree from the side thereof nearest the base plate. A frame member is connected at one end to said other end of the base plate and extends inwardly beneath the base plate. A second blade at the inner end of the frame member bites into the side of a tree opposite the side thereof engaged by the first blade. Means is carried by the base plate for detachably attaching the base plate to the feet of a person standing thereon.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
251 words
A tree climbing platform comprising: (a) a horizontal base plate having rigid side members projecting beyond one end thereof in position to extend alongside opposite sides of a tree with said one end of said base plate being out of operative engagement with and spaced from the adjacent side of said tree so that no force is transmitted from said one end of said base plate to the side of said tree adjacent thereto and the other end of said base plate extending away from said tree, (b) a first transverse blade carried by said rigid side members in position to bite into the opposite side of a tree from the side thereof nearest said one end of said base plate, (c) a frame member pivotally connected at one end thereof to said other end of said base plate in spaced relation to said one end of said base plate and disposed to extend downwardly and inwardly beneath said base plate, (d) a second transverse blade carried by the inner end of said frame member in position to bite into the side of a tree opposite the side thereof engaged by said first transverse blade, (e) means carried by said base plate for detachably attaching said base plate to the feet of a person standing thereon, and (f) locking means operatively connecting said frame member to said base plate and adapted to retain said inner end of said frame member and said base plate at fixed positions relative to each other.

A tree climbing platform comprising: (a) a horizontal base plate having rigid side members projecting beyond one end thereof in position to extend alongside opposite sides of a tree with said one end of said base plate being out of operative engagement with and spaced from the adjacent side of said tree so that no force is transmitted from said one end of said base plate to the side of said tree adjacent thereto and the other end of said base plate extending away from said tree, (b) a first transverse blade carried by said rigid side members in position to bite into the opposite side of a tree from the side thereof nearest said one end of said base plate, (c) a frame member pivotally connected at one end thereof to said other end of said base plate in spaced relation to said one end of said base plate and disposed to extend downwardly and inwardly beneath said base plate, (d) a second transverse blade carried by the inner end of said frame member in position to bite into the side of a tree opposite the side thereof engaged by said first transverse blade, (e) means carried by said base plate for detachably attaching said base plate to the feet of a person standing thereon, and (f) locking means operatively connecting said frame member to said base plate and adapted to retain said inner end of said frame member and said base plate at fixed positions relative to each other.
Claim 3
Dependent Claim
24 words
A tree climbing platform as defined in claim 1 in which said first and second transverse blades are generally V-shaped as viewed in plan.
Claim 4
Dependent Claim
29 words
A tree climbing platform as defined in claim 1 in which means is provided for detachably connecting said first transverse blade to said side members at selected longitudinal positions.
Claim 5
Dependent Claim
61 words
A tree climbing platform as defined in claim 3 in which said means for detachably connecting said first transverse blade to said side members comprises openings through end portions of said first transverse blade adapted to move into alignment with openings in said side members and retaining members passing through said openings securing said first transverse blade to said side members.
Claim 6
Dependent Claim
51 words
A tree climbing platform as defined in claim 4 in which a plurality of said openings are provided in each said side member in longitudinally spaced relation to each other for receiving said retaining members so that said first transverse blade may be secured to said side members at selected positions.
Claim 7
Dependent Claim
25 words
A tree climbing platform as defined in claim 1 in which said one end of said base plate is recessed inwardly toward the center thereof.
Claim 8
Dependent Claim
41 words
A tree climbing platform as defined in claim 1 in which said inner end of said frame member is movable selectively to an inoperative position alongside said base plate and to an operative position downwardly and away from said base plate.
Claim 9
Dependent Claim
49 words
A tree climbing platform as defined in claim 7 in which said locking means operatively connecting said frame member to said base plate is adapted to lock said frame member in said operative position upon movement of said frame member away from said base plate to said operative position.
Claim 10
Dependent Claim
89 words
A tree climbing platform as defined in claim 8 in which said locking means comprises: (a) at least one arm pivotally connected at one end to said frame member, (b) a transverse pin-like member carried by the other end of said arm, (c) there being an elongated slot in the side member of said base plate disposed to receive said pin-like member, and (d) an offset recess in said elongated slot disposed to receive said pin-like member in response to movement of said frame member to said operative position.
Claim 11
Dependent Claim
37 words
A tree climbing platform as defined in claim 1 in which at least one foot engaging member is carried by said base plate in position to overlie the feet of a person standing on said base plate.
