Abstract
Abstract A tree-climbing hunter's support apparatus includes a tree-gripping frame section and a collapsible frame section that extends from the tree-gripping section to unfold and support a flexible lounge seat. The positioning of the seat for supporting a hunter provides for a strong and safe tree-gripping lever action to prevent the apparatus from slipping down the tree. The flexible lounge seat permits the hunter to remain safe, comfortable and motionless for long periods. The hunter can climb and descend the tree with the assistance of the apparatus, and can conveniently transport the apparatus on his back.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
130 words
An apparatus for engaging trees and the like for supporting a person above the ground, comprising: a first openable frame section surrounding the trunk of a tree and including a first pair of parallel tubular arms joined by an upper tree-engaging member and a lower tree-engaging member, said first frame section gripping said tree upon the exertion of downward pressure on said lower tree-engaging member; a second frame section telescopically mounted to said first frame section by a second pair of parallel arms slidably receivable within said first pair of arms and joined by a support member, for selective extension of said support member in a direction away from said tree; and a flexible seat suspended between said first frame section and said support member of said second frame section.
Claim 2
Independent Claim
130 words
An apparatus for engaging trees and the like for supporting a person above the ground, comprising: a first openable frame section surrounding the trunk of a tree and including a first pair of parallel tubular arms joined by an upper tree-engaging member and a lower tree-engaging member, said first frame section gripping said tree upon the exertion of downward pressure on said lower tree-engaging member; a second frame section telescopically mounted to said first frame section by a second pair of parallel arms slidably receivable within said first pair of arms and joined by a support member, for selective extension of said support member in a direction away from said tree; and a flexible seat suspended between said first frame section and said support member of said second frame section.
Claim 3
Dependent Claim
33 words
The apparatus of claim 1 further comprising a third frame section collapsibly mounted to said second frame section for selective extension of a foot support member in a direction away from said tree.
Claim 4
Dependent Claim
137 words
The apparatus of claim 1 wherein said first frame section includes a first pair of parallel, tubular arms; said upper tree-engaging member comprises a removable brace connecting said first arms; said lower tree-engaging member comprises a cross member joining said first arms in spaced apart relation intermediate the length of said arms and a pair of diagonal cleats each extending between said cross member and one of said first arms to form a "V" opening toward said tree; said second frame section includes a second pair of parallel tubular arms slidably receivable within said first arms for telescoping movement, said support member joining said second arms at the ends thereof farthest from said first arms; and said flexible seat comprises woven fabric extending from said cross member to said support member between said first and second arms.
Claim 5
Independent Claim
217 words
An apparatus for engaging trees and the like for supporting a person above the ground, comprising: a first openable frame section surrounding the trunk of a tree and including a first pair of parallel, tubular arms, an upper tree-engaging member comprising a removable brace connecting said first arms, and a lower tree-engaging member comprising a cross member joining said first arms in spaced apart relation intermediate the length of said arms and a pair of diagonal cleats each extending between said cross member and one of said first arms to form a "V" opening toward said tree, said first frame section gripping said tree upon the exertion of downward pressure on said lower tree-engaging member; a second frame section collapsibly mounted to said first frame section for selective extension of a support member in a direction away from said tree, said second frame section including a second pair of parallel tubular arms slidably receivable within said first arms for telescoping movement, said support member joining said second arms at the ends thereof farthest from said first arms; and a flexible seat suspended between said first frame section and said support member of said second frame section, said flexible seat comprising woven fabric extending from said cross member to said support member between said first and second arms.
Claim 6
Independent Claim
