Claim 1

Independent Claim 304 words

A tree platform comprising: a generally rectangular frame comprising: a generally V-shaped rear side edge frame member adapted to horizontally engage a tree, a pair of first and second, opposite, side frame members extending from said rear edge frame member, a front side frame member extending from said opposite side frame members, a plurality of spaced tubular frame members extending from one side frame member to an opposite side frame member and generally parallel with and between said rear side edge frame member and said first side frame member, a plurality of parallel strip members extending across, perpendicular to, said tubular frames member on an upper side of said spaced tubular frame members and attached to said tubular frame members, a layer of fabric attached over an upper side of said strips and forming a supporting surface for a user; a plurality of removable pads positioned between said spaced tubular frame members, whereby sound deadening and appearance camouflage may be effected; foot strap means secured to the top of said frame through said fabric for overlying and securing the feet of a person standing on the fabric; first and second side arm members pivotally attached to opposite frontal regions of said side frame members and extendable rearward at an angle with respect to the plane of said platform frame; a V-shaped tree engaging member extending between end regions of said first and second side arm members; and a first support arm pivotally attached to and extending from a generally rear region of said first side frame member upward and forward to, and pivotally attached to, said first side arm member and a second support arm pivotally attached to and extending from a generally rear region of second said side frame member upward and forward to, and pivotally attached to, said second side arm member.

Claim 2

Dependent Claim 304 words

A tree platform comprising: a generally rectangular frame comprising: a generally V-shaped rear side edge frame member adapted to horizontally engage a tree, a pair of first and second, opposite, side frame members extending from said rear edge frame member, a front side frame member extending from said opposite side frame members, a plurality of spaced tubular frame members extending from one side frame member to an opposite side frame member and generally parallel with and between said rear side edge frame member and said first side frame member, a plurality of parallel strip members extending across, perpendicular to, said tubular frames member on an upper side of said spaced tubular frame members and attached to said tubular frame members, a layer of fabric attached over an upper side of said strips and forming a supporting surface for a user; a plurality of removable pads positioned between said spaced tubular frame members, whereby sound deadening and appearance camouflage may be effected; foot strap means secured to the top of said frame through said fabric for overlying and securing the feet of a person standing on the fabric; first and second side arm members pivotally attached to opposite frontal regions of said side frame members and extendable rearward at an angle with respect to the plane of said platform frame; a V-shaped tree engaging member extending between end regions of said first and second side arm members; and a first support arm pivotally attached to and extending from a generally rear region of said first side frame member upward and forward to, and pivotally attached to, said first side arm member and a second support arm pivotally attached to and extending from a generally rear region of second said side frame member upward and forward to, and pivotally attached to, said second side arm member.

Claim 3

Dependent Claim 35 words

A platform as set forth in claim 1 further comprising at least one second strip member extending parallel with said plurality of strip members on the underside of and attached to said tubular frame members.

Claim 4

Dependent Claim 74 words

A platform as set forth in claim 1 wherein the side arm members are each formed of front and rear mutually telescoping members, each said support arm pivotally connects to a rear telescoping member, and the length of a support arm and front telescoping member together have a length approximately equal to the distance between connections of a said side arm member to a said side frame member and a said side frame member.
