Abstract

The wall covering of the present invention comprises an elongated horizontal siding member having at its lower edge a U-shaped female locking flange. A separate horizontal bottom strip is adapted to be connected to the wall adjacent the lower edge of the horizontal siding member. The bottom strip includes a male locking flange sized to frictionally fit within and be retentively held in the female locking flange of the horizontal siding member. The interlocking relationship between the bottom strip and the lower edge of the siding member provides positive securement of the lower edge of the siding member to the wall.

Claims

1. A wall covering for attachment to a wall, said covering comprising:

an elongated horizontal siding member having an upper edge and a lower edge,

first securing means for attaching said upper edge of said siding member to said wall,

a horizontal bottom strip having in cross section a single thickness comprising an upper vertical surface, a first angled surface extending downwardly from said vertical surface and outwardly away from the vertical plane of said vertical surface, a second angled surface extending downwardly and outwardly from said vertical plane at a steeper angle than said first angled surface, and a male locking flange extending inwardly toward said vertical plane from the lower edge of said second angled surface;

second securing means for attaching said upper vertical surface of said strip to said wall;

said elongated siding member having a female locking flange at the lower edge thereof, said female locking flange extending inwardly toward said vertical plane and retentively surrounding and embracing said male locking flange of said bottom strip so as to be held against movement by said bottom strip;

said siding member extending downwardly at an angle which is substantially the same as said steeper angle of said second surface and being in facing engagement with the entire surface of said second angled surface;

said male and female locking flanges being spaced outwardly from said vertical plane sufficiently far to permit manual access between said vertical plane and said male and female locking flanges together;

said male locking flange having in cross section a horizontal portion extending from said lower edge of said second angled surface to an inner edge spaced from said vertical plane, said male locking flange further including a lip portion extending upwardly from said inner edge of said horizontal portion;

said female locking flange having in cross section a horizontal portion and a lip portion surrounding and embracing said horizontal and lip portions of said male locking member;

said lip portion of said female locking flange having a bead portion extending toward said lip portion of said male locking flange for retentively locking said male and female locking flanges together in nested relationship;

said lip portion of said male locking flange having an outward projection extending toward said lip portion of said female locking flange at a point below said bead portion whereby said outward projection and said bead portion engage one another to retentively hold said male and female locking flanges in nested relationship;

said second securing means comprising horizontally spaced apart vertically elongated holes permitting horizontal adjustment of said bottom strip around said wall.

2. A wall covering according to claim 1 wherein said lip portion of said male locking flange includes in cross section a plurality of vertically spaced apart projections extending toward said lip portion of said female locking flanges, said bead portion of said female locking flange protruding into the space between two of said spaced apart projections so as to retentively lock said male and female flanges in nested relationship.
