Abstract

Abstract This invention relates to insert strips for a floor covering structure for public walking areas such as in foyers of commercial buildings. The floor structure is made up of connected longitudinal sections, each section having a central longitudinal channel, a raised removable strip being disposed into each channel, to provide a walking surface and the strip having a relatively friction free underlying surface for an easy insertion into a channel and the same being arranged to be retained in the channel.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 139 words
In combination with a floor covering structure of coupled sections, each section having a central longitudinal channel having transversely opposed facing grooves, an insert strip in combination with said channel, said strip comprising an upper layer portion formed as an extrusion of a fairly hard durometer plastic material, an underlying layer portion of a durometer harder than that of said upper layer portion and co-extruded therewith, said upper layer portion having a width to extend across the width of a channel of the floor covering section, said underlying layer having a width extending beyond each side of said upper layer portion to project into grooves formed at each side of said channel, said underlying layer portion having a substantially slick friction free surface, and said upper layer portion having formed into its upper surface portion a figured surface treatment.
Claim 2
Dependent Claim 139 words
In combination with a floor covering structure of coupled sections, each section having a central longitudinal channel having transversely opposed facing grooves, an insert strip in combination with said channel, said strip comprising an upper layer portion formed as an extrusion of a fairly hard durometer plastic material, an underlying layer portion of a durometer harder than that of said upper layer portion and co-extruded therewith, said upper layer portion having a width to extend across the width of a channel of the floor covering section, said underlying layer having a width extending beyond each side of said upper layer portion to project into grooves formed at each side of said channel, said underlying layer portion having a substantially slick friction free surface, and said upper layer portion having formed into its upper surface portion a figured surface treatment.
Claim 3
Dependent Claim 23 words
The structure of claim 1 wherein, said upper layer portion is formed of a suitable PVC compound to have a firm yielding surface.
Claim 4
Dependent Claim 28 words
The structure of claim 1, wherein said underlying layer portions being formed of a suitable PVC compound of a hard durometer providing a relatively friction free bottom surface.
Claim 5
Dependent Claim 33 words
The structure of claim 1, wherein said underlying layer portion has a durometer sufficiently harder than that of said upper layer portion to provide a firm base for embossing said upper layer portion.
Claim 6
Dependent Claim 12 words
The structure of claim 1, wherein said underlying layer portion is colorless.
Claim 7
Dependent Claim 14 words
The structure of claim 1, wherein said surface treatment comprises a multiplicity of projections.
Claim 8
Dependent Claim 29 words
The structure of claim 1, wherein said upper layer has formed thereon a plurality of spaced longitudinally extending ribs, and means intersect said ribs forming a multiplicity of projections.
Claim 9
Dependent Claim 13 words
The structure of claim 1, wherein said underlying layer being transversely substantially inflexible.
