Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
148 words
Apparatus for supporting a person at a selected height in a tree in the form of a sit and climb tree stand having a pair of independent assemblies positionable in spaced relation on a tree, each assembly comprising: (a) a generally rectangular frame extending from one side of the tree, said frame having a plurality of rigid tubular members extending longitudinally and transversely therein; (b) a platform member affixed to said frame for supporting a person thereon; (c) a tree engaging bar in the form of a V having a pair of spaced apart legs offset from each other, said legs releasably attached to said frame such that said legs receive a tree of variable diameter in wedging engagement therebetween and support said frame therefrom; and (d) means for urging said frame outwardly from said tree in selectable increments to position said platform in a generally horizontal plane.
Claim 2
Dependent Claim
148 words
Apparatus for supporting a person at a selected height in a tree in the form of a sit and climb tree stand having a pair of independent assemblies positionable in spaced relation on a tree, each assembly comprising: (a) a generally rectangular frame extending from one side of the tree, said frame having a plurality of rigid tubular members extending longitudinally and transversely therein; (b) a platform member affixed to said frame for supporting a person thereon; (c) a tree engaging bar in the form of a V having a pair of spaced apart legs offset from each other, said legs releasably attached to said frame such that said legs receive a tree of variable diameter in wedging engagement therebetween and support said frame therefrom; and (d) means for urging said frame outwardly from said tree in selectable increments to position said platform in a generally horizontal plane.
Claim 3
Dependent Claim
95 words
Apparatus as defined in claim 1 wherein said frame comprises: (a) a first and second spaced apart longitudinal frame member; (b) at least two transverse frame members attached to and extending between said longitudinal frame members, defining a platform plane; (c) a first and second supporting frame member attached to said longitudinal frame member distal said tree, extending upwardly therefrom at an acute angle, and adapted for attachment to said tree engaging bar proximal said tree; and (d) at least two vertical members connecting said longitudinal frame member and supporting frame member proximal said tree.
Claim 4
Dependent Claim
185 words
Apparatus for supporting a person at an elevation on a column-like member such as a tree, comprising: (a) a frame assembly having a generally rectangular bottom section and a pair of lateral members extending at an acute angle from one end of said bottom section over said bottom section; (b) a platform member affixed to said bottom section for supporting a person thereon; (c) an engagement in the form of a V having a first and second leg, with each leg detachably affixed to one of said lateral members distal said one end of said bottom section, said first and second legs being positioned to receive a column-like member therebetween in wedging engagement; and (d) means for displacing said bottom section of said frame assembly from a column-like member which is engaged between said legs to hold said platform in a substantially horizontal displacement including a generally Y-shaped member adapted to abut said column-like member, means for slidably attaching said Y-shaped member to said frame assembly intermediate said frame assembly and said column-like member and means for biasing said Y-shaped member toward said column-like member.
Claim 5
Dependent Claim
185 words
Apparatus for supporting a person at an elevation on a column-like member such as a tree, comprising: (a) a frame assembly having a generally rectangular bottom section and a pair of lateral members extending at an acute angle from one end of said bottom section over said bottom section; (b) a platform member affixed to said bottom section for supporting a person thereon; (c) an engagement in the form of a V having a first and second leg, with each leg detachably affixed to one of said lateral members distal said one end of said bottom section, said first and second legs being positioned to receive a column-like member therebetween in wedging engagement; and (d) means for displacing said bottom section of said frame assembly from a column-like member which is engaged between said legs to hold said platform in a substantially horizontal displacement including a generally Y-shaped member adapted to abut said column-like member, means for slidably attaching said Y-shaped member to said frame assembly intermediate said frame assembly and said column-like member and means for biasing said Y-shaped member toward said column-like member.
Claim 6
Dependent Claim
265 words
Apparatus for supporting a person at an elevation on a column-like member such as a tree, comprising: (a) a frame assembly having a generally rectangular bottom section and a pair of lateral members extending at an acute angle from one end of said bottom section over said bottom section; (b) a platform member affixed to said bottom section for supporting a person thereon; (c) an engagement bar in the form of a V having a first and second leg offset from each other with each leg detachably affixed to one of said lateral members distal said one end of said bottom section, said first and second legs being positioned to receive a column-like member therebetween in wedging engagement; and (d) means for displacing said bottom section of said frame assembly from a column-like member which is engaged between said legs to hold said platform in a substantially horizontal displacement including a generally Y-shaped member having one elongated member disposed normal to said column-like member and a pair of engaging members diverging from said elongated member, said elongated member having a plurality of longitudinally spaced apertures therein, a tubular member integral with said frame assembly opposite said one end of said bottom section adapted to sliding receive said elongated member therein and having at least one aperture therein, resilient means disposed within said tubular member for urging said elongated member outwardly of said tubular member, and a plunger adapted for insertion through said aperture in said tubular member and within one of said plurality of longitudinally spaced apertures to releasably lock said elongated member in position.
Claim 7
Dependent Claim
265 words
Apparatus for supporting a person at an elevation on a column-like member such as a tree, comprising: (a) a frame assembly having a generally rectangular bottom section and a pair of lateral members extending at an acute angle from one end of said bottom section over said bottom section; (b) a platform member affixed to said bottom section for supporting a person thereon; (c) an engagement bar in the form of a V having a first and second leg offset from each other with each leg detachably affixed to one of said lateral members distal said one end of said bottom section, said first and second legs being positioned to receive a column-like member therebetween in wedging engagement; and (d) means for displacing said bottom section of said frame assembly from a column-like member which is engaged between said legs to hold said platform in a substantially horizontal displacement including a generally Y-shaped member having one elongated member disposed normal to said column-like member and a pair of engaging members diverging from said elongated member, said elongated member having a plurality of longitudinally spaced apertures therein, a tubular member integral with said frame assembly opposite said one end of said bottom section adapted to sliding receive said elongated member therein and having at least one aperture therein, resilient means disposed within said tubular member for urging said elongated member outwardly of said tubular member, and a plunger adapted for insertion through said aperture in said tubular member and within one of said plurality of longitudinally spaced apertures to releasably lock said elongated member in position.
Claim 8
Dependent Claim
27 words
Apparatus as defined in claim 4 further comprising a first stabilizer bar rigidly affixed to one of said engaging members and slidably engaged within said frame assembly.
Claim 9
Dependent Claim
23 words
Apparatus as defined in claim 4 further comprising means for biasing said plunger toward engagement in said one aperture in said tubular member.
