Total Claims: 13
Claim 1
Independent Claim
127 words
A corner structure for joining siding for a building with walls, comprising a panel with inner and outer surfaces, top and bottom edges, and side edge; a second panel with inner and outer surfaces, top and bottom edges, and a side edge inverted U-shaped flange aligned adjacent the top edge of each; the bottom edge of each panel with an inwardly extending step and upturned flange; one panel being provided with a side edge comprising a U-shaped flange; the other panel having a side edge with a track; the track comprising an overlapping portion and an underlapping portion aligned substantially perpendicular to the surfaces of the panel; the track slidingly engaging the U-shaped flange of a corresponding second panel to form a structurally rigid and weather-tight corner;
