Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
148 words
A flooring system comprising elongated tubular slats having given shaped end openings adapted to pass fluid therethrough, means for laterally joining said slats in a laterally adjacent and parallel planar series to form a floor panel, a pair of fluid manifolds for respectively enclosing opposite ends of said slats of said floor panel, said manifolds each being a series of segmented fluid couplers having openings respectively complemental to and longitudinally connected with said slat openings to form longitudinal fluid passing extensions of said slats, said manifold coupler segments having given shaped lateral openings adjacent said slat ends, and coupler joints having outwardly opposed surfaces complemental to adjacent ones of said lateral segment openings and secured to said manifold segments between adjacent segment openings to normally engage said lateral segment openings to seal and separate said adjacent lateral openings and for joining adjacent coupler segments to form said manifolds.
Claim 2
Dependent Claim
148 words
A flooring system comprising elongated tubular slats having given shaped end openings adapted to pass fluid therethrough, means for laterally joining said slats in a laterally adjacent and parallel planar series to form a floor panel, a pair of fluid manifolds for respectively enclosing opposite ends of said slats of said floor panel, said manifolds each being a series of segmented fluid couplers having openings respectively complemental to and longitudinally connected with said slat openings to form longitudinal fluid passing extensions of said slats, said manifold coupler segments having given shaped lateral openings adjacent said slat ends, and coupler joints having outwardly opposed surfaces complemental to adjacent ones of said lateral segment openings and secured to said manifold segments between adjacent segment openings to normally engage said lateral segment openings to seal and separate said adjacent lateral openings and for joining adjacent coupler segments to form said manifolds.
Claim 3
Dependent Claim
62 words
A flooring system as defined in claim 1 wherein said coupler joints are provided with a frangible wall normally extending laterally across said adjacent coupler openings to normally seal said openings to prevent passage of fluid between said coupler joints, whereby said wall could be selectively broken out of said coupler joint to provide a passage interconnection between said adjacent manifold couplers.
Claim 4
Dependent Claim
42 words
A flooring system as defined in claim 1 wherein said manifold couplers are provided with a frangible panel, and a conduit enclosing said frangible panel and extending from said coupler to open into said coupler enclosure when said frangible panel is removed.
Claim 5
Dependent Claim
97 words
A flooring system as defined in claim 1 wherein said coupler joints are provided with a frangible wall normally extending laterally across said adjacent coupler openings to normally seal said openings to prevent passage of fluid between said coupler joints, whereby said wall could be selectively broken out of said coupler joint to provide a passage interconnection between said adjacent manifold couplers, and wherein said manifold couplers are provided with a frangible panel, and a conduit enclosing said frangible panel and extending from said coupler to open into said coupler enclosure when said frangible panel is removed.
Claim 6
Dependent Claim
26 words
A flooring system as defined in claim 1 wherein said tubular slats are provided with a laterally domed surface to provide individual drainage of said slats.
Claim 7
Dependent Claim
31 words
A flooring system as defined in claim 1 wherein said tubular slats are provided with laterally extending grooves and ridges for a floor surface to provide lateral drainage for said slats.
Claim 8
Dependent Claim
31 words
A flooring system as defined in claim 5 wherein said tubular slats are provided with laterally extending grooves and ridges for a floor surface to provide lateral drainage for said slats.
