Flexible J-channel for masking siding
First Claim
Patent Images
1. A covered building exterior comprising:
- (a) an exterior wall;
(b) a vinyl, aluminum or wood siding panel affixed to said exterior wall and having a curved marginal portion; and
(c) an elongated J-channel for masking said curved marginal portion of the siding panel, said J-channel comprising;
(i) a base channel including a base wall and front and rear edge portions extending upwardly from said base wall, said base wall comprising a relatively rigid polymer composition having a durometer hardness of about 95 Shore A;
(ii) a rear wall extending upwardly from the rear edge portion of said base channel, said rear wall being affixed to said exterior wall behind said siding panel by means of a nail or screw, said rear wall being uninterrupted by slits and consisting essentially of a relatively flexible polymer composition having a durometer hardness of about 80 Shore A; and
(iii) a retainer wall extending upwardly from said front edge portion and retaining said non-linear marginal portion of the siding panel adjacent said building exterior, said retainer wall comprising a relatively flexible polymer composition having a durometer hardness of about 80 Shore A.

Abstract
A flexible J-channel for masking marginal portions of siding on buildings. The J-channel has a relatively rigid base wall and relatively flexible rear and retainer walls which allow flexing when the J-channel is bent in an arc. The uncut flexible rear wall provides excellent resistance to moisture penetration.

4. An elongated J-channel for masking non-linear marginal portions of siding on building, said J-channel being coextruded from a relatively flexible polymer composition and a relatively rigid polymer composition having a higher durometer hardness than said relatively flexible polymer composition, and comprising:
-
(a) a base channel including a base wall and front and rear edge portions each extending upwardly from said base wall, said base wall comprising said relatively rigid polymer composition; (b) a retainer wall for retaining marginal portions of siding adjacent a building exterior, said retainer wall extending upwardly from said front edge portion, said retainer wall comprising said relatively flexible polymer composition; and (c) a rear wall for attachment to a building exterior, said rear wall extending upwardly from said rear edge portion and extending above said base wall a greater distance than said retainer wall, said rear wall being integrally formed without interruption by slits and consisting of said relatively flexible polymer composition. - View Dependent Claims (5, 6, 7, 8, 9)

10. A method for masking arcuate marginal portions of siding on a building exterior comprising the steps of:
-
(a) providing a flexible elongated J-channel comprising a coextruded polyvinyl chloride composition and having spaced first and second lateral end portions, and further comprising; (i) a base channel of a relatively rigid polymer composition; (ii) a retainer wall extending upwardly from a front edge portion of said base channel, said retainer wall having a relatively flexible polymer composition; and (iii) a rear wall integrally formed with said base channel and uninterrupted by slits, said rear wall extending upwardly from a rear edge portion of said base channel a greater distance than said retainer wall, said rear wall consisting essentially of relatively flexible polymer composition, said base channel having a higher durometer hardness than said retainer wall and said rear wall; and (b) fastening said rear wall to a building exterior adjacent a first lateral end portion; (c) bending said J-channel in an arc without slitting said rear wall; (d) fastening said rear wall to said building exterior at a plurality of locations paced laterally along said rear wall between the first and second lateral end portions; and (e) receiving and retaining a generally arcuately extending marginal portion of vinyl, aluminum or wood siding between said retainer wall and said rear wall. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
