CROSS-REFERENCE TO RELATED APPLICATION

The instant application claims priority to U.S. Provisional Patent Application Ser. No. 60/969,366, filed Aug. 31, 2007, the entire specification of which is expressly incorporated herein by reference.

FIELD OF THE INVENTION

The present invention relates generally to an exterior trim system with corner trim pieces used in decorating exteriors of buildings. More specifically, the present invention relates to an exterior trim system comprising corner trim pieces, including those formed from polyvinyl chloride (PVC), that are configured for concealing siding and providing an aesthetically pleasing finished appearance to an exterior of a building.

BACKGROUND OF THE INVENTION

Exterior trim pieces are well known in the art for finishing exteriors of buildings to provide an aesthetically pleasing finished appearance. Traditionally, wood has been used to form these trim pieces. One particular example of this is seen in older clapboard houses in which wood trim provides a finished appearance to wood clapboards. Unfortunately, wood is subject to degradation from insects, wind, rain, sun, and other environmental elements. PVC or “vinyl” siding was eventually developed as a substitute for wood. Vinyl siding was found to be durable and weather resistant. To compliment the use of vinyl siding, exterior trim pieces were also developed that were similarly durable and weather resistant. Often such pieces are used to finish inside and outside wall corners of a building that has been covered in vinyl siding. Examples of such trim pieces are shown in U.S. Pat. No. 5,090,174 to Fragale.

Fragale appears to disclose exterior trim pieces that are preferably formed of metal of about 0.013 gauge with a foam substrate laminated to the metal. The foam substrate provides insulation to the trim pieces. Each of the trim pieces has an integral J-channel that receives siding to conceal ends of the siding and provide an aesthetically pleasing appearance to an exterior of a building. Installation of the trim pieces comprises simply applying an adhesive to the foam substrate and adhering the trim pieces to the exterior. An outer surface of the metal layer can be embossed with a wood grain, painted in any color, or striated with a colored PVC coating.

U.S. Pat. No. 5,542,222 to Wilson et al. appears to show similar exterior trim pieces to those of Fragale. The trim pieces of Wilson et al., however, can be formed of PVC with an inner support member adhered to the PVC for strengthening the trim pieces. These PVC trim pieces also include integral J-channels for receiving and concealing siding ends. The J-channels include flanges that abut the exterior of the building. Wilson et al. suggests using fasteners such as nails to secure the flanges to the exterior thereby securing the trim pieces to the building.

Accordingly, there exists a need for new and improved exterior trim systems, including those comprising corner trim pieces, that are configured for concealing siding and providing an aesthetically pleasing finished appearance to an exterior of a building, that overcome at least one of the aforementioned problems.
