Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
166 words
A scaffold platform comprising a thin deck plate of generally rectangular shape, a pair of joists underlying and secured to said deck plate at closely spaced intervals, said joists being generally parallel to and spaced from each other and each disposed adjacent an edge of said deck plate with opposed ends extending beyond the corresponding ends of the plate, at least a portion of each joist including one of the projecting ends being U-shaped in cross section with a pair of outwardly bent flanges extending in opposed transverse directions from the top of the joist and serving as the portion of the joist connected to said deck plate, said portion being adapted to receive a male end extending from an adjacent platform, the opposite projecting end of the joist being a male member adapted to be received in the Ushaped projecting end of another adjacent platfoRm, said male and female ends having registering notches for supporting the platforms on the cross rods of a scaffolding framework.
Claim 2
Dependent Claim
166 words
A scaffold platform comprising a thin deck plate of generally rectangular shape, a pair of joists underlying and secured to said deck plate at closely spaced intervals, said joists being generally parallel to and spaced from each other and each disposed adjacent an edge of said deck plate with opposed ends extending beyond the corresponding ends of the plate, at least a portion of each joist including one of the projecting ends being U-shaped in cross section with a pair of outwardly bent flanges extending in opposed transverse directions from the top of the joist and serving as the portion of the joist connected to said deck plate, said portion being adapted to receive a male end extending from an adjacent platform, the opposite projecting end of the joist being a male member adapted to be received in the Ushaped projecting end of another adjacent platfoRm, said male and female ends having registering notches for supporting the platforms on the cross rods of a scaffolding framework.
Claim 3
Dependent Claim
117 words
A scaffold platform comprising decking elongated in one direction, at least one stiffener joist disposed beneath said decking to extend along its elongated direction and protruding from the ends thereof, and a multiplicity of connecting means firmly securing said joist or joists to said decking at closely spaced intervals along said elongated direction, one of said protruding ends of the stiffener joist being a female member receiving and supporting a male member of an adjacent scaffold platform and the other end being a male member receivable in a female member of another adjacent scaffold platform, said members being notched to be received and supported by cross rods of a scaffolding framework extending transversely of said elongated direction.
Claim 4
Dependent Claim
117 words
A scaffold platform comprising decking elongated in one direction, at least one stiffener joist disposed beneath said decking to extend along its elongated direction and protruding from the ends thereof, and a multiplicity of connecting means firmly securing said joist or joists to said decking at closely spaced intervals along said elongated direction, one of said protruding ends of the stiffener joist being a female member receiving and supporting a male member of an adjacent scaffold platform and the other end being a male member receivable in a female member of another adjacent scaffold platform, said members being notched to be received and supported by cross rods of a scaffolding framework extending transversely of said elongated direction.
Claim 5
Dependent Claim
20 words
The scaffold platform of claim 2 in which said notches are disposed directly beneath the end of said deck plates.
Claim 6
Dependent Claim
65 words
The scaffold platform of claim 4 in which said stiffener joist is a flanged U-shaped member, the flanges extending transversely of the legs in opposed directions and serving as the portions of the joist secured to the decking, and in which one of the flanges of said joist is elongated and bent to fit over and butt against an adjacent edge of the deck plate.
