Abstract

Abstract An injection molded end cap for attachment to the terminal end of an extrusion. The end cap includes a projecting skirt which cooperates with a complimentary upper surface of the extrusion for producing a gentle transition and covering a junction therebetween. The abutting ends between end cap and terminal end of the extrusion may be secured to each other by heat sealing, adhesives, and the like.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 178 words
A decorative trim strip attachable to an underlying surface of a substrate, comprising: an elongate extrusion having at least one terminal end and including an upper longitudinally extending shaped surface, said upper shaped surface in cross-section having a flat bottom surface; an end cap for attachment to the terminal end of said extrusion and constructed to accommodate both an undersized and oversized extrusion, said end cap including a body having a terminal end which is sized and shaped to conform to the size and shape of the terminal end of said extrusion, the terminal end of said end cap having a flexible skirt projecting from the upper edge thereof which extends over and contacts the upper shaped surface of said extrusion; said flexible skirt being bent inwardly to conform to said undersized extrusion and being adapted to be flexibly deflected outwardly to conform to said oversized extrusion; and means for securing said end cap and said extrusion to an underlying surface of a substrate wherein the skirt produces a smooth transition between said end cap and said extrusion.
Claim 2
Dependent Claim 178 words
A decorative trim strip attachable to an underlying surface of a substrate, comprising: an elongate extrusion having at least one terminal end and including an upper longitudinally extending shaped surface, said upper shaped surface in cross-section having a flat bottom surface; an end cap for attachment to the terminal end of said extrusion and constructed to accommodate both an undersized and oversized extrusion, said end cap including a body having a terminal end which is sized and shaped to conform to the size and shape of the terminal end of said extrusion, the terminal end of said end cap having a flexible skirt projecting from the upper edge thereof which extends over and contacts the upper shaped surface of said extrusion; said flexible skirt being bent inwardly to conform to said undersized extrusion and being adapted to be flexibly deflected outwardly to conform to said oversized extrusion; and means for securing said end cap and said extrusion to an underlying surface of a substrate wherein the skirt produces a smooth transition between said end cap and said extrusion.
Claim 3
Dependent Claim 25 words
The invention defined in claim 1 wherein the skirt projecting from said end cap is shaped the same as the upper surface of said extrusion.
Claim 4
Dependent Claim 17 words
The invention defined in claim 2 wherein said skirt is tapered in thickness toward its terminal end.
