Abstract

A composite door with a lite utilizes panels with aligned cutouts and a foam retainer member which extends about the cutouts between the panels to effect a seal. The retainer has a mounting portion extending inwardly from the cutout periphery. The lite is disposed in the cutout and it is secured by an external frame which has portions overlying the outer surface of the panel and its marginal portion. A clamp secured to the foam retainer and external frame and clamps the lite to the external frame, and an internal frame has portions overlying the outer surface of the other panel and the marginal portion of the other surface of the lite and conceals the clamp and fastener.

Claims

1. A composite door with a lite comprising:

(a) a pair of spaced panels providing the faces of the door and having aligned cutouts therein;

(b) a foam retaining member extending about the periphery of said cutouts with a first portion extending between said panels to effect a seal therewith and a mounting portion extending inwardly of said periphery of said cutouts;

(c) a translucent lite configured cooperatively with said cutouts and disposed therein;

(d) an external frame element extending about said periphery of said cutout in one of said panels and having a first portion overlying the outer surface of said one panel about said cutout and a second portion overlying said mounting portion and a marginal portion of the adjacent surface of said lite;

(e) engaging means securing said mounting portion of said foam retaining member and said external frame element in assembly and clamping said lite to said external frame element;

(f) an internal frame element extending about said periphery of said cutout in the other of said panels and having a first portion overlying the outer surface of said other panel about said cutout and a second portion overlying said mounting portion of said retaining member, a marginal portion of the other surface of said lite and said engaging means; and

(g) cellular synthetic resin in a cavity defined by said panels and said foam retaining member, said cellular synthetic resin abutting said form retaining member.

2. The composite door of claim 1 wherein said foam retaining member is of generally T-shaped configuration with a head portion extending between said panels to effect said seal and a base portion providing said mounting portion.

3. The composite door of claim 1 wherein said panels have inwardly extending lips about said cutouts and said foam retaining member abuts the interior surface of said lips.

4. The composite door of claim 1 wherein said engaging means includes (a) a clamping plate bearing upon the surface of said lite opposite from that adjacent said external frame element and (b) threaded fasteners extending through said clamping plate and said mounting portion of said foam retaining member and engaging said external frame element, whereby tightening of said threaded fasteners draws said external frame element towards said plate.

5. The composite door of claim 4 wherein said clamping plate has a generally L-shaped portion overlying said marginal portion of said lite and a portion of its peripheral edge and a flange which extends over said mounting portion of said foam retaining member, said fasteners extending through said flange and mounting portion.

6. The composite door of claim 5 wherein said interior frame element second portion has a projection which is frictionally engaged between said foam retaining member and said L-shaped portion of said clamping plate.

7. The composite door of claim 6 wherein said projection is dimensioned and configured to snap fit into spacing between said frame retaining member and L-shaped portion of said clamping plate.

8. The composite door of claim 1 wherein said foam retaining member is fabricated of synthetic resin.

9. The composite door of claim 1 including sealing means between said lite and said outer frame element.

10. A method for forming a composite door having a lite comprising the steps of:

(a) assembling a pair of substantially planar rectangular door panels in spaced relationship with cutouts formed therein in substantial alignment;

(b) placing a foam retaining member in said cutouts with a first portion extending between said panels in sealing relationship with said panels about said cutouts and a second portion extending inwardly of the periphery of said cutouts;

(c) introducing synthetic resin foam into the cavity defined by said panels and said foam retaining member;

(d) inserting a translucent lite into said cutouts; and

(e) securing said lite to said foam retaining member by;

(i) providing an external lite frame element on the external surface of one of said panels and said lite;

(ii) placing a lite clamping element against the other surface of said lite; and

(iii) securing said external lite frame element and said lite clamping element to said second portion of said foam retaining member to clamp said lite between said lite clamping element and said frame element.

11. The method of forming a door with a lite in accordance with claim 10 wherein said external lite frame element securing step is effected by fasteners extending between said lite clamping element and external lite frame element through said second portion of said foam retaining member.

12. The method of forming a door with a lite in accordance with claim 10 wherein said lite securing step includes placing an internal lite frame element against said lite in a position overlying said lite clamping element and securing it in assembly with said lite and foam retaining member.

13. The method of forming a door with a lite in accordance with claim 10 including the step of forming said panels with inwardly extending lips about said cutouts and wherein said placing step places said first portion of said foam retaining member against the interior surface of said lips to effect said sealing relationship.

14. The method of forming a door with a lite in accordance with claim 12 wherein said lite is of lesser dimension than said cutout to provide a spacing thereabout and there is included the step of forming said internal lite frame element with a portion dimensioned to seat into a spacing between said foam retaining member and a portion of said lite clamping element and frictionally engaging said dimensioned portion in said space.

15. The method of forming a door with a lite in accordance with claim 10 including the step of placing sealing material between adjacent surfaces of said lite and said external lite frame element.
