Abstract
Abstract A system for the fabrication of edging configurations on countertops and the like employs an elongate edge moulding element having a continuous rib thereon. A complementary groove is provided parallel to the edge of the countertop sheet on the underside of the sheet to receive the rib and locate the edge moulding element reliably and accurately for the glueing operation.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
103 words
For use in the fabrication of counter tops and the like formed from sections of flat sheet material, an edge moulding element comprising: a straight elongate strip of substantially constant profile, said strip including at least one straight longitudinally extending flat surface and projecting rib means extending longitudinally with respect to said flat surface and projecting outwardly thereof, the arrangement being such that said rib means can be inserted in a groove provided on the underside of a section of said flat sheet material parallel to an edge thereof to locate said edge mounting element in a predetermined location relative to said edge.
Claim 2
Dependent Claim
103 words
For use in the fabrication of counter tops and the like formed from sections of flat sheet material, an edge moulding element comprising: a straight elongate strip of substantially constant profile, said strip including at least one straight longitudinally extending flat surface and projecting rib means extending longitudinally with respect to said flat surface and projecting outwardly thereof, the arrangement being such that said rib means can be inserted in a groove provided on the underside of a section of said flat sheet material parallel to an edge thereof to locate said edge mounting element in a predetermined location relative to said edge.
Claim 3
Dependent Claim
14 words
An edge moulding element according to claim 1 fabricated in solid homogeneous plastics material.
Claim 4
Dependent Claim
16 words
An edge moulding element according to claim 1 wherein said rib means has a rounded profile.
Claim 5
Dependent Claim
20 words
An edge moulding element according to claim 1 wherein said rib means is continuous throughout the length of the element.
Claim 6
Dependent Claim
37 words
An edge moulding element according to claim 1 wherein said rib means is located along one side of said flat surface, adjacent a second surface of the element that is at right angles to said flat surface.
Claim 7
Dependent Claim
26 words
An edge moulding element according to claim 1 wherein a major portion of the profile of the element apart from said one flat surface is rounded.
Claim 8
Dependent Claim
33 words
An edge moulding element according to claim 1 including a second longitudinally extending flat surface opposite and parallel to said first mentioned flat surface and also having a projecting rib means associated therewith.
Claim 9
Dependent Claim
26 words
An edge moulding element according to claim 1 wherein adjacent to opposite edges of said flat surface are two further flat surfaces at right angles thereto.
Claim 10
Dependent Claim
13 words
A edge moulding element according to claim 1 wherein the profile is rectangular.
Claim 11
Dependent Claim
25 words
An edge moulding element according to claim 9 wherein there is a chamfer between two surfaces of the moulding element other than said flat surface.
Claim 12
Dependent Claim
25 words
An edge moulding element according to claim 9 wherein there is a rounded intersection between two surfaces of said element other than said flat surface.
Claim 13
Dependent Claim
38 words
An edge moulding element according to claim 9 wherein in a surface of said element at right angles to said flat surface there is a longitudinally extending groove of a profile complementary to that of said rib means.
Claim 14
Dependent Claim
25 words
An edge moulding element according to claim 9, having a right-angled longitudinally extending recess at a corner between two surfaces other than said flat surface.
Claim 15
Dependent Claim
83 words
A countertop comprising a flat sheet of homogeneous plastics material having a straight edge thereon, and an edge moulding element according to claim 9 of the same material as said sheet, said sheet having a continuous groove extending thereon at a predetermined distance from said straight edge and adapted to receive said rib means therein such that when the rib means is so received, a second surface of said edge moulding element is positioned at a desired location relative to said straight edge.
Claim 16
Independent Claim
132 words
A method of fabricating an edge moulding on a countertop or the like comprising: providing a flat sheet of material having a straight edge thereon and a groove extending parallel to said edge at a predetermined distance therefrom; providing an edge moulding element of substantially constant profile, said element having a flat surface extending longitudinally thereof, projecting rib means extending longitudinally on said flat surface, and a nose surface adjacent to one side of said flat surface; positioning said edge moulding element with said flat surface in contact with the surface of the underside of flat sheet and the rib means in engagement with said groove thereby to locate said nose surface at a desired location relative to said edge; and securing said edge moulding element thus positioned to said flat sheet.
Claim 17
Independent Claim
132 words
A method of fabricating an edge moulding on a countertop or the like comprising: providing a flat sheet of material having a straight edge thereon and a groove extending parallel to said edge at a predetermined distance therefrom; providing an edge moulding element of substantially constant profile, said element having a flat surface extending longitudinally thereof, projecting rib means extending longitudinally on said flat surface, and a nose surface adjacent to one side of said flat surface; positioning said edge moulding element with said flat surface in contact with the surface of the underside of flat sheet and the rib means in engagement with said groove thereby to locate said nose surface at a desired location relative to said edge; and securing said edge moulding element thus positioned to said flat sheet.
Claim 18
Dependent Claim
13 words
A method according to claim 15 wherein said securing effected by adhesive bonding.
Claim 19
Dependent Claim
34 words
A method according to claim 15 wherein said edge moulding element and said flat sheet are both of plastics material, and said securing is effected by adhesive bonding with the aid of clamp means.
