Prefabricated shell assembly for window trim
| Details |
Inventors: Stanizzo, John A.;
Assignee:
Primary Examiner: Perham; Alfred C.
Assistant Examiner:
Attorney, Agent or Firm:
A trim assembly comprising an integral trim member having a generally L-shaped cross-section, in which one leg of the L is adapted for attachment to a wall to serve as the casement, while the other leg (flange section) projecting towards the window is adapted for attachment to the jamb surface of the window opening. The interior surface of the flange section is provided with closely-spaced, longitudinal grooves extending the length of the trim member. These grooves, preferably spaced at a distance of about 1/8 to 1/2 inch, are easily cut or broken off whereby the width can readily be modified to properly fit a wide variety of jamb-widths. The instant trim member, featuring a flange projecting towards the window, permits for the design of a hollow enclosure which can serve as a housing for a small blower to provide a source of flowing, preferably heated, air. The blower will preferably be incorporated within the sill-trim member, having ducts connected to similar ducts in the side-trim members and/or in the head-trim member, in turn communicating with inclined outlet apertures. Thus, air from the blower motor may be conducted through the ducts and exit the apertures so as to flow over the window surface, preferably as a sheet of air, thereby preventing condensation on the windows and the resulting moisture damage to surfaces in proximity therewith. In an alternate embodiment, the blower rather than being housed within a trim member, may be housed directly within the window frame, similarly to provide a source of moving air over the surface of the window. |

DETAILED DESCRIPTION I claim: 1.
A shell assembly comprised of trim members for the interior surrounds of a substantially rectangular window opening, said trim members being joined together so as to form the trim facing for said window; each such trim member being comprised of (i) an elongated casing section having an interior surface adapted for attachment to the wall surrounding said window opening, the inner longitudinal edge of said casing section being joined with and substantially perpendicular to (ii) an elongated border section, having a length commensurate with the length of said casing section and a width of from about 1/2 to 6 inches, the interior surface of said border section being adapted for attachment to the jamb surface which is perpendicular to the plane of the wall and to the plane of the window, a major portion of said interior surface having longitudinal grooves therein, said grooves being parallel to each other and to the free longitudinal edge of said border section, and being spaced from each other a distance of about 1/8 to 1/2 inch, permitting said width readily to be modified to correspond with the depth between the wall and the window rail, so as to fit properly therebetween when said trim member is attached to the wall, wherein the border section of at least one of said side trim members has an interior surface constructed to provide at least one approximately longitudinal channel between said interior surface and said jamb surface, in which a portion of said channel near one end thereof can be connected to a source of air under a pressure greater than ambient, while another portion near the other end thereof connects to an aperture penetrating the thickness of said border section at an acute angle thereto, whereby air flowing through said channel and said aperture will be caused to flow over the inner surface of the window and prevent condensation thereon.
2.
The shell assembly of claim 1, wherein said trim members are constructed from plastic material, and said casing section is integral with said border section
