Claim 1
Independent Claim 131 words
A portable seat adapted for use with a tree or like generally vertically extending member, said seat comprising: a mounting member having a first tree engaging portion and a spaced second tree engaging portion, said member dimensioned to at least partially encircle a tree with the first and second tree engaging portions abutting the tree on opposite sides thereof; a seat support arm extending outwardly from one of said portions; a seat member; and pivot and biasing means for pivotally securing said seat member to said seat support arm whereby said mounting member may be positioned around a tree with said first and second portions engaging opposite sides of the tree and the seat member may pivot relative to said seat support and assume a horizontal position relative to the ground.
Claim 2
Dependent Claim 131 words
A portable seat adapted for use with a tree or like generally vertically extending member, said seat comprising: a mounting member having a first tree engaging portion and a spaced second tree engaging portion, said member dimensioned to at least partially encircle a tree with the first and second tree engaging portions abutting the tree on opposite sides thereof; a seat support arm extending outwardly from one of said portions; a seat member; and pivot and biasing means for pivotally securing said seat member to said seat support arm whereby said mounting member may be positioned around a tree with said first and second portions engaging opposite sides of the tree and the seat member may pivot relative to said seat support and assume a horizontal position relative to the ground.
Claim 3
Dependent Claim 23 words
A portable seat as defined by claim 1 further including a heat retaining member secured to the upper surface of said seat member.
Claim 4
Dependent Claim 28 words
A portable seat as defined by claim 2 wherein said mounting member is generally C-shaped and further including protective padding on said first and second tree engaging portions.
Claim 5
Dependent Claim 25 words
