Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
236 words
An ornamental fence having an exterior coloration of a fluid contained therewithin, said ornamental fence comprising: first and second elongated hollow vertically extending pickets; first and second elongated hollow horizontally extending rails structurally connected to said pickets, said pickets and said rails being defined by a thin exterior surface formed of a translucent material and establishing a fluid containing reservoir in each of said pickets and a fluid containing reservoir in each of said rails; fluid passages formed in said pickets and said rails fluidly interconnecting said fluid containing reservoirs in said pickets with said fluid containing reservoirs in said rails, said translucent material being substantially free of pigmentation to provide a transparency to said exterior surface enabling said pickets and said rails to assume the coloration of the fluid contained in said fluid containing reservoirs; a filling opening in an upper end of at least one of said pickets for admitting said fluid into said fluid containing reservoirs of said pickets and through said fluid passages into said fluid containing reservoirs of said rails; and a draining opening in a lower end of at least one of said pickets for draining the fluid in the fluid containing reservoirs; and said fluid having the coloration admitted through said filling openings and filling said fluid containing reservoirs whereby said coloration of said fluid imparts a similar coloration to said exterior surfaces of said pickets and said rails.
Claim 2
Dependent Claim
236 words
An ornamental fence having an exterior coloration of a fluid contained therewithin, said ornamental fence comprising: first and second elongated hollow vertically extending pickets; first and second elongated hollow horizontally extending rails structurally connected to said pickets, said pickets and said rails being defined by a thin exterior surface formed of a translucent material and establishing a fluid containing reservoir in each of said pickets and a fluid containing reservoir in each of said rails; fluid passages formed in said pickets and said rails fluidly interconnecting said fluid containing reservoirs in said pickets with said fluid containing reservoirs in said rails, said translucent material being substantially free of pigmentation to provide a transparency to said exterior surface enabling said pickets and said rails to assume the coloration of the fluid contained in said fluid containing reservoirs; a filling opening in an upper end of at least one of said pickets for admitting said fluid into said fluid containing reservoirs of said pickets and through said fluid passages into said fluid containing reservoirs of said rails; and a draining opening in a lower end of at least one of said pickets for draining the fluid in the fluid containing reservoirs; and said fluid having the coloration admitted through said filling openings and filling said fluid containing reservoirs whereby said coloration of said fluid imparts a similar coloration to said exterior surfaces of said pickets and said rails.
Claim 3
Dependent Claim
224 words
An ornamental fence having an exterior coloration of a fluid contained therewithin, said ornamental fence comprising: first and second elongated picket members interconnected by first and second rail members extending transversely therebetween, said picket members and said rail members being defined by a thin exterior surface formed of a translucent material and establishing a fluid containing reservoir in each of said picket members and a fluid containing reservoir in each of said rail members; a fluid passage formed in said picket members and said rail members fluidly interconnecting said fluid containing reservoirs in said picket members with said fluid containing reservoirs in said rail members, said translucent material being substantially free of pigmentation to provide a transparency to said exterior surface enabling said picket members and said rail members to assume the coloration of the fluid contained in said fluid containing reservoirs; a filling opening in one end of at least one of said picket members for admitting the fluid into said fluid containing reservoirs of said picket members and through said fluid passage into said fluid containing reservoirs of said rail members; and a draining opening in the other end of at least one of said picket members for draining the fluid in the fluid containing reservoir whereby said coloration of said fence may be changed by changing the coloration of said fluid.
Claim 4
Dependent Claim
224 words
An ornamental fence having an exterior coloration of a fluid contained therewithin, said ornamental fence comprising: first and second elongated picket members interconnected by first and second rail members extending transversely therebetween, said picket members and said rail members being defined by a thin exterior surface formed of a translucent material and establishing a fluid containing reservoir in each of said picket members and a fluid containing reservoir in each of said rail members; a fluid passage formed in said picket members and said rail members fluidly interconnecting said fluid containing reservoirs in said picket members with said fluid containing reservoirs in said rail members, said translucent material being substantially free of pigmentation to provide a transparency to said exterior surface enabling said picket members and said rail members to assume the coloration of the fluid contained in said fluid containing reservoirs; a filling opening in one end of at least one of said picket members for admitting the fluid into said fluid containing reservoirs of said picket members and through said fluid passage into said fluid containing reservoirs of said rail members; and a draining opening in the other end of at least one of said picket members for draining the fluid in the fluid containing reservoir whereby said coloration of said fence may be changed by changing the coloration of said fluid.
Claim 5
Dependent Claim
27 words
The ornamental fence as recited in claim 2 wherein said picket members and said rail members are formed of a transparent plastic material substantially free of pigmentation.
Claim 6
Dependent Claim
20 words
The ornamental fence as recited in claim 2 wherein said rail members are inclined with respect to said picket members.
