Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
76 words
The combination comprising a deck, said deck having an upper sloped surface to permit runoff of water, a net over said deck, said net having an upper surface, said net including means extending into contact with said sloped upper surface of said deck for maintaining runoff space beneath the plane of the upper surface of said net, substantially all of the spaces within said net being open, and a water penetrable sheet material overlying said net.
Claim 2
Dependent Claim
76 words
The combination comprising a deck, said deck having an upper sloped surface to permit runoff of water, a net over said deck, said net having an upper surface, said net including means extending into contact with said sloped upper surface of said deck for maintaining runoff space beneath the plane of the upper surface of said net, substantially all of the spaces within said net being open, and a water penetrable sheet material overlying said net.
Claim 3
Dependent Claim
14 words
The combination of claim 1 in which said water penetrable sheet is a carpet.
Claim 4
Dependent Claim
15 words
The combination of claim 1 in which said sheet material is secured to said net.
Claim 5
Dependent Claim
96 words
The combination comprising a deck, said deck having an upper sloped surface to permit runoff of water, a net over said deck, said net including a plurality of sets of plastic strands, said sets of strands defining openings therebetween, substantially all of said openings being free of obstruction to the runoff of water, said net having an upper surface, said net including means extending into contact with said sloped surface of said deck for maintaining runoff space beneath the plane of the upper surface of said net, and a water penetrable sheet material overlying said net.
Claim 6
Dependent Claim
96 words
The combination comprising a deck, said deck having an upper sloped surface to permit runoff of water, a net over said deck, said net including a plurality of sets of plastic strands, said sets of strands defining openings therebetween, substantially all of said openings being free of obstruction to the runoff of water, said net having an upper surface, said net including means extending into contact with said sloped surface of said deck for maintaining runoff space beneath the plane of the upper surface of said net, and a water penetrable sheet material overlying said net.
Claim 7
Dependent Claim
14 words
The combination of claim 4 in which said water penetrable sheet is a carpet.
Claim 8
Dependent Claim
15 words
The combination of claim 4 in which said sheet material is secured to said net.
Claim 9
Dependent Claim
145 words
The combination comprising a deck, said deck having an upper sloped surface to permit runoff of water, a net over said deck, said net having an upper surface, said net including a plurality of sets of strands, the strands of one of said nets being parallel plastic strands extending into contact with said sloped upper surface of said deck for maintaining runoff space beneath the plane of the upper surface of said net, the parallel strands of said one set being arranged generally downward of the slope of said sloped surface to provide with said surface channels for water runoff, substantially all of the spaces within said net being open, and the strands of another set being arranged at an angle to the strands of said one set and intersecting the strands thereof to maintain the strands of said one set in spaced parallel relationship.
Claim 10
Dependent Claim
145 words
The combination comprising a deck, said deck having an upper sloped surface to permit runoff of water, a net over said deck, said net having an upper surface, said net including a plurality of sets of strands, the strands of one of said nets being parallel plastic strands extending into contact with said sloped upper surface of said deck for maintaining runoff space beneath the plane of the upper surface of said net, the parallel strands of said one set being arranged generally downward of the slope of said sloped surface to provide with said surface channels for water runoff, substantially all of the spaces within said net being open, and the strands of another set being arranged at an angle to the strands of said one set and intersecting the strands thereof to maintain the strands of said one set in spaced parallel relationship.
Claim 11
Dependent Claim
168 words
The combination comprising a deck, said deck having an upper sloped surface to permit runoff of water, a net over said upper sloped surface, said net having a plurality of sets of plastic strands, the strands of one set intersecting the strands of another set to form joints at said intersections integral with the strands forming the joint, the upper surface of the strands of said one set and of the strands of said other set being substantially in a common plane, the lower surface of the strands of said one set being in engagement with said upper sloped surface of said deck and thereby supporting said net, the strands of said one set also being arranged generally downward of the slope of said deck to form with said deck channels for runoff of water, and the lower surface of the strands of said other set being spaced above said upper sloped surface of said deck whereby water may run off said upper sloped surface of said deck.
Claim 12
Dependent Claim
168 words
The combination comprising a deck, said deck having an upper sloped surface to permit runoff of water, a net over said upper sloped surface, said net having a plurality of sets of plastic strands, the strands of one set intersecting the strands of another set to form joints at said intersections integral with the strands forming the joint, the upper surface of the strands of said one set and of the strands of said other set being substantially in a common plane, the lower surface of the strands of said one set being in engagement with said upper sloped surface of said deck and thereby supporting said net, the strands of said one set also being arranged generally downward of the slope of said deck to form with said deck channels for runoff of water, and the lower surface of the strands of said other set being spaced above said upper sloped surface of said deck whereby water may run off said upper sloped surface of said deck.
Claim 13
Dependent Claim
16 words
The combination of claim 8 in which the strands forming one of said sets are parallel.
Claim 14
Dependent Claim
25 words
The combination of claim 8 in which the strands of said one set intersect the strands of said other set at substantially a right angle.
