Description
~ 2~ 22236-563 BACKGROUND OF THE IN~ENTION
At-tempts have been made in the past -to construct various -types of door assemblies. A door assembly which is installed as an exterior door should be dimen-tionally stable to reduce energy losses through -the opening. Relatively severe t~mperature differentials occur on such ex-terior door assemblies. One of the major problems with prior art door assemblies has been excessive deflection and warping caused by such temperature differentials. Traditional wood doors suffer from splitting and cracking in addition to long-term moisture absorption which results in warping.
Another problem which has not been resolved by prior art door assemblies is the appearance of the door. In situations where simulated wood door appearances have been desired, attempts have been made to obtain the "wood" appearance -through the use of veneers and other surface trea-tments. Customers are generally familiar with the texture and the differences in graining of a wood door. Therefore, unless this same -type of texture and graining, for example edge graining, is dupli-cated, the wood simula-ted door assembly is unsatisfactory from an appearance viewpoint.
Another problem is the installation of a door assembly.
In the rehabilitation market and even in new construction, it is often necessary to trim the door assembly prior to installation within the door frame. This was often difficult to do when using prior art door assemblies.

The perimeter frame 23 is adhesively bonded -to the inner and outer compression molded polyester skins 21,22. The core 24 comprises a rigid urethane foam having a density of .8 pounds per cubic foot to 3.5 pounds per cubic foot.
Referring to Figure 1, the perimeter frame 23 extends outwardly from -the edge 31 of the panels or skins 21,22. The extension is 1/4 inch from the vertical edge 31 of the skin 21.
This permits the trimming of the door assembly 20 with conventional woodworking -tools.
The perimeter frame 23 includes horizontal rails 33 and vertical stiles 34. Referring to Figures 2 and 9, a plurality of horizontally extending grippers 37 having sharp outer edges, are molded on the inner sides 28 of the skins 21 and 22. A rail positioning member 38 also projects inwardly from the top and bottom surfaces of the inner sides 28 of the skins 21,22. As shown in Figures 3 and 4, -the rails 33 about the rail positioning member 38. The grippers 37 pierce the surface of the rails 33 and aid in preventing undesired relative motion between the rails 33 and the skins 21,22.
A plurality of vertically extending projections 40 are positioned inwardly from the inner sides 28 of the skins 21,22. As best shown in Figures 5 and 6, the pro~ections 40 ~;~3~
engage -the stiles 3~ of -the perimeter f.rame 23. In the present embodiment, a pair of -the vertically extending projections ~0 are provided or defined along each edge of the skin 21 or 22.
It has been found that a door assembly 20 with compre-ssion molded skins, as described above, provides a door assembly which has dimensional stability in various environmental conditions together with a pleasing appearance.
It has been found that the exterior surface of -the door assembly 20 may be stained with a wood stain or with a topcoat, such as urethane topcoat.
While the present embodiment shown in Figure 1, is directed to a nine unit "raised panel" design, simulating a wood door having a similar appearance, it is understood that various other designs may be constructed in accordance with the present invention without departing f.rom the appended claims.
