Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
108 words
A self-standing all plastic floor sign comprising two panels hinged together at their upper ends for selectively folding and spreading the lower ends of the panels apart, one panel having an integral tubular hinge portion at its upper end provided with a longitudinal slot in its lower portion, the other panel having an integral core rotatable in said tubular hinge portion, said core having a laterally directed U-shaped notch adapted to allow the core to hook into and pass laterally through said slot into said tubular hinge portion by simultaneously rotating and pressing radially inward on the core to snap it past the upper edge of said slot.
Claim 2
Dependent Claim
108 words
A self-standing all plastic floor sign comprising two panels hinged together at their upper ends for selectively folding and spreading the lower ends of the panels apart, one panel having an integral tubular hinge portion at its upper end provided with a longitudinal slot in its lower portion, the other panel having an integral core rotatable in said tubular hinge portion, said core having a laterally directed U-shaped notch adapted to allow the core to hook into and pass laterally through said slot into said tubular hinge portion by simultaneously rotating and pressing radially inward on the core to snap it past the upper edge of said slot.
Claim 3
Dependent Claim
47 words
A self-standing all plastic floor sign as described in claim 1, wherein the lower edge of said U-shaped notch is provided with a sharp corner adapted to snap past the upper edge of said longitudinal slot and to prevent subsequent withdrawal of the core through the slot.
Claim 4
Dependent Claim
44 words
A self-standing all plastic floor sign as described in claim 2, wherein a neck on said other panel connects it to said core, and a transverse rib on said neck limits rotation of the core by engagement with the upper edge of said slot.
Claim 5
Dependent Claim

A self-standing all plastic floor sign as described in claim 1, wherein a cap on the outer end of said core is adapted to abut the outer end of said tubular hinge portion when the core is inserted therein.
Claim 6
Dependent Claim
46 words
A self-standing all plastic floor sign as described in claim 1, wherein a transverse slot divides said core into outer and inner portions and an arcuate rib on said tubular hinge portion received in said transverse slot divides said longitudinal slot into outer and inner portions.
Claim 7
Dependent Claim
52 words
A self-standing all plastic floor sign as described in claim 5, wherein the lower edge of said U-shaped notch in said core portions is provided with a sharp corner adapted to snap past the upper edge of said longitudinal slot portions and to prevent subsequent withdrawal of the core through the slot.
Claim 8
Dependent Claim
47 words
A self-standing all plastic floor sign as described in claim 6, wherein a neck on said other panel connects it to said core portions, and a transverse rib on said neck limits rotation of said core portions by engagement with the upper edge of said longitudinal slot.
Claim 9
Dependent Claim
33 words
A self-standing all plastic floor sign as described in claim 7, wherein said transverse slot dividing said core portions extends into said neck and divides said transverse rib into outer and inner portions.
