Abstract

A trim piece for sealing a work surface including a body having a first side, a second side, and a span disposed between the first side and the second side, wherein the first side and the second side are joined at a junction defining an angle between the first side and the second side of between 80 degrees and 100 degrees, a topcap is affixed to the span of the body, wherein the topcap includes a left side having a first wing and a right side having a second wing, an adhesive is bonded to the first side of the body and an aperture is disposed within the body.

Claims

1. A trim piece for sealing a joint in a work surface, the joint being formed where two structures meet at an inside angle, the trim piece comprising:

an elongate unitary structure of indeterminate length which when viewed in cross section, includes;

a body having a generally triangular section portion and presenting a first wing portion and an opposed second wing portion and an intervening decorative surface on an outwardly visible face extending between the first wing portion and the second wing portion;

the first wing portion and the second wing portion extending outwardly away from the generally triangular section portion and terminating in a substantially knife edge;

an adhesive portion, the adhesive portion extending at least partially over two inward faces of the generally triangular section and the adhesive portion presenting a first adhesive face and a second adhesive face, a first imaginary extension of the first adhesive face intersecting the first wing portion and a second imaginary extension of the second adhesive face intersecting the second wing portion such that a first outward portion of the first wing portion extends beyond the first imaginary extension when the first wing portion is undeformed and a second outward portion of the second wing portion extends beyond the second imaginary extension when the second wing portion is undeformed and when the adhesive is uncompressed;

the trim piece being formed from a flexible polymer material having a flexible resiliency such that the first wing portion and the second wing portion are each deformed generally outwardly by contact with one of the two structures and wherein the first wing portion and the second wing portion establish a generally sealing relationship with the two surfaces and wherein the adhesive portion adheres to the two surfaces and establishes an equilibrium with the flexible resiliency of the polymer material such that the first outward portion and the second outward portion are each in deformed sealing contact with the first structure and the second structure. and

wherein the first wing portion and the second wing portion have a wing flexure of approximately one hundred fourteen grams when utilizing a wing flex test.

2. The trim piece as claimed in claim 1, wherein the body further presents a radius indentation adjacent each of the first wing portion and the second wing portion.

3. The trim piece as claimed in claim 1, wherein when viewed in cross section, the adhesive extends continuously over at least partially over the two inward faces and over a rounded intersection between the two inward faces.

4. The trim piece as claimed in claim 1, wherein the adhesive is a coextrusion with the body.

5. The trim piece as claimed in claim 1, wherein the body, when viewed in cross section, further comprises a nipple extending inwardly away from the outwardly visible face.

6. The trim piece as claimed in claim 1, wherein the adhesive is a silicone adhesive having a one hundred eighty degree peel adhesion of approximately thirty five ounces per inch.

7. The trim piece as claimed in claim 1, wherein the body is formed from a polyurethane polymer having a durometer of approximately sixty to seventy based on the Shore A scale.
