Abstract
A simple, relatively low cost system for sealing an ordinary roller shade with respect to the window frame sides, top and bottom is provided. The roller shade seal system essentially comprises a pair of edge seal assemblies in the form of elongate mounting strip members adapted to be permanently mounted to opposite vertical faces of the window frame trim, and a pair of sealing strip members in the form of elongate, generally U-shaped channels adapted to sealably engage the latter edges of the shade, releasably mounted to an associated mounting strip. The window shade sealing system is completed by a shade bottom edge seal comprising a rigid bottom strip reinforcing member, a sill sealing strip and a shade top sealing member.
Claims10
A roller shade seal system for a window shade comprising in combination:
- a pair of edge seal assemblies in the form of elongate mounting strip members, adapted to be mounted to opposite faces of the window frame trim, and a pair of sealing strip members in the form of elongate, generally U-shaped channels adapted to sealably engage lateral edges of a said shade;
- elongate snap-coupling means extending the length of said edge seal assemblies for releasably mounting each of said sealing strip members to an associated mounting strip member, adapted for mounting either one of said members within a window frame opening and on the surface of a window frame opening, said snap-coupling means comprising elongate bead means and socket means with the mounting strip members carrying one of the bead means and socket means while the sealing strip members carry the other of the bead means and socket means, the mounting strip members being reversible for alternative mounting in a window frame opening and on the face of a window frame opening, the socket means and bead means projecting from their respective carrying members at approximately 45.degree. to the plane to be occupied by the shade, thereby to provide the alternative mounting wherein said bead means and socket means are adapted to accommodate up to approximately 30.degree. of angular misalignment of a sealing strip member to a mounting strip member, mounted thereto, about the longitudinal direction of said bead means;
- a shade bottom edge seal assembly comprising a rigid bottom strip reinforcing member for mounting onto the bottom end of a said shade;
- and a window sill sealing strip means adapted and arranged to cooperate with said shade bottom reinforcing member to provide a seal at said window sill;
- and
- a shade top seal having mounted thereon a resiliently deformable sealing means for sealably engaging the outer turn of a said shade adjacent the roller end.
