Abstract
The disclosure herein describes a door assembly wherein the front and rear sides each consist of a pair of opposite metallic stiles and of upper and lower metallic cross pieces which, when assembled, define a rectangular opening in the door. A rectangular frame is disposed at the periphery of this opening and is connected to the stiles and cross pieces through a series of moldings. Wood spacers are located at the outer periphery of the stiles and cross pieces while a core of rigid foam fills the interior space defined by the spacers, the stiles, the cross pieces and the moldings to form a bonded door. A second rectangular molding frame is used to secure a window unit inserted in the opening to the bonded structure.
Description
-` 2135369 TIT~B OF THB INVENTION
An insulated door assembly.
FIELD OF THB lNv~..lON
The present invention relates to an insulated door assembly having an insert, such as a window unit, and, more particularly, to the type of door assemblies having an insulating core for providing thermal and sound insulating characteristics.
In typical door assemblies in which is inserted a window unit, such insert is usually locked into the door opening by means of screws or other type of fastening devices.
However, such doors are constructed in accordance with the manner in which they are to be installed to a door frame, i.e. to open from the right or to open to the left. At present, a door cannot be mounted for both installations as, in one of the two situations, the fastening devices would be visible.
Hence, this lack of versatility in door constructions is a problem for inventories where both types of doors must be kept before being installed.
There are various methods of fabricating foam filled door assemblies having inserts. For example, such _` 2135369 ~- 2 doors are described in U.S. patent No. 4,327,535 issued May 4, 1982 to Governale, in U.S. patent No. 4,546,585 issued October 15, 1985 to Governale and in laid-open Canadian patent application No. 2,044,331 filed June 11, 1991.
However, none of these methods avoid the above described problem of lack of versatility.
OBJECT8 AND STATEMENT OF THE lNv~N.ION
In accordance with the present invention, there is provided a unique construction of a door assembly wherein a single foam filled wind~w structure is formed for both above described situations of installation and wherein a window unit may be inserted to the structure, either at the door manufacturing plant or at the window assembling plant.
This is achieved by providing a door assembly formed of spacers, stiles, cross pieces and moldings so assembled as to form a structural door filled with insulation. The assembled parts define an opening into which a window unit may be subsequently inserted and secured in place by means of a window molding frame.
In accordance with the present invention, the door assembly comprises:

However, none of these methods avoid the above described problem of lack of versatility.
OBJECT8 AND STATEMENT OF THE lNv~N.ION
In accordance with the present invention, there is provided a unique construction of a door assembly wherein a single foam filled wind~w structure is formed for both above described situations of installation and wherein a window unit may be inserted to the structure, either at the door manufacturing plant or at the window assembling plant.
This is achieved by providing a door assembly formed of spacers, stiles, cross pieces and moldings so assembled as to form a structural door filled with insulation. The assembled parts define an opening into which a window unit may be subsequently inserted and secured in place by means of a window molding frame.
In accordance with the present invention, the door assembly comprises:
2~35~69 a first side consisting of a pair of opposite metallic stiles and upper and lower metallic cross pieces extending between the stiles;
an opposite second side consisting of a pair of opposite metallic stiles and upper and lower metallic cross pieces extending between these stiles;
the upper cross pieces of the first and second sides being spaced from the lower cross pieces of the first and second sides to define, between the stiles, a rectangular opening in the door; each stile and each cross piece having outer edges and flanged inner edges facing the opening; each cross piece including flanged side edges;
a rectangular frame peripherally received in the~opening;
a pair of non metallic stile spacers disposed peripherally between the outer edges of the stiles of the first and second sides;
a pair of non metallic cross spacers disposed peripherally between the outer edges of the cross pieces of the first and second sides;
a pair of opposite first stile moldings having means engaging the flanged inner edges of the stiles and the flanged side edges of the cross pieces;
a pair of opposite second stile moldings having means engaging the flanged inner edges of the stiles and the flanged side edges of the cross pieces;
a pair of opposite first cross moldings having means engaging the flanged inner edges of the cross pieces;
a pair of opposite second cross moldings having S means engaging the flanged inner edges of the cross pieces;
a core of rigid foam filling the interior space defined between the spacers, the stiles, the cross pieces and the moldings and adhering to the inner faces of the spacers, stiles, cross pieces and mouldings to form a bonded structure; and window molding means peripherally received in the opening opposite to the rectangular frame; the molding means and the frame each having cooperating inter-engaging means so that, after a window unit has been inserted in the opening, the inter-engaging means cooperate to secure the window unit in the opening of the bonded structure.
In one form of the invention, the moldings are M-shaped in cross-section with a pair of recesses, one recess receiving the flanged inner edges, the other recess receiving the flanged sides edges or the frames, or both.
In another form of the invention, the window molding means define a second rectangular peripheral frame.
_` 21~5369 In another form of the invention, some flanged inner edges and the side edges have C-shaped resilient extremities which are forcingly insertable in the recesses of the M-shaped moldings.
Other objects and further scope of applicability of the present invention will become apparent from the detailed description given hereinafter.
It should be understood, however, that this detailed description, while indicating preferred embodiments of the invention, is given by way of illustration only, since various changes and modifications within the spirit and scope of the invention will become apparent to those skilled in the art.
Figure 1 is an elevational view showing the front side of a door assembly according to the present invention;
Figure 2 is an exploded perspective view thereof;
Figure 3 is a cross-sectional view taken along lines 3-3 of figure 1;
Figure 4 is a cross-sectional view taken along lines 4-4 of figure 1;
Figure 5 is a cross-sectional view taken along lines 5-5 of figure 1;
Figure 6 is an enlarged cross-sectional view showing the connection of a molding with one of the non metallic cross pieces of the door assembly.
Figure 7 is a cross-sectional view similar to that of figure 3 showing another embodiment of the present invention; and Figure 8 is a cross-sectional view similar to that of figure 4 showing this other embodiment.
The following description will refer to front and rear sides of a door assembly; however, these words have been used to simplify the description and to avoid confusion if words such as first and second sides were employed. It is understood that either side of the door may be the front or the rear.
Hence, figure 1 shows the front side of a door assembly 10 consisting of a pair of opposite metallic stiles 12 and 14 and upper and lower metallic cross pieces 16 and 18 extending between the front side stiles.
Referring to figure 2, the rear side of the door assembly consists of a pair of opposite metallic stiles 20 and 22 and upper and lower metallic cross pieces 24 and 26 extending between the rear side stiles.
213~369 _. .
The upper cross pieces 16 and 24 are spaced from the lower cross pieces 18 and 26 to define, between themselves and the stiles, a rectangular opening in which is subsequently received a window unit 28, such as a single glass panel or a pair of guillotine-type windows.
A pair of non metallic stile spacers 30 and 32 are disposed at the periphery of the stiles terminating at the outer edges thereof. Also, a pair of non metallic cross spacers 34 and 36 are disposed at the periphery of the cross pieces terminating at the outer edges thereof.
A pair of opposite front stile moldings 38 and 40 extends along the inner edges of the stiles 12 and 14 while another pair of rear stile moldings 42 and 44 extends along the inner edges of the stiles 20 and 22.
A pair of opposite front cross moldings 46 and 48 extends along the inner edges of the cross pieces 16 and 18 while another pair of opposite rear cross moldings 50 and 52 extends along the inner edges of the opposite cross pieces 24 and 26. These moldings are made of resilient plastic material.
The door assembly 10 comprises also front and rear rectangular frames 54 and 56 to which is fixed the window unit 28 as explained hereinbelow. These frames are made of rigid plastic material.
213~369 _ Figures 3, 4 and 5 are cross sections at different areas of the door assembly of figure 1 when all the components shown in figure 2 are assembled. All moldings 38, 40, 42, 44, 46, 48, S0 and 52 are M-shaped in cross sections, each defining a pair of recesses.
However, it will be noted that the cross section of moldings 46 and 50 (figure 3) as well as that of moldings 48 and 52 is somewhat different from the cross section of moldings 40 and 44 (figures 4 and 5) and of moldings 38 10and 42. Indeed, moldings 46, 48, 50, 52 display a pair of slotted recesses while moldings 38, 40, 42, 44 display a pair of rectangular grooves having a restricted entrance.
As can be seen in figure 2, the longitudinal 15rectangular stiles 12, 14, 20 and 22 have flanged inner and outer edges while the cross pieces 16, 18, 24 and 26 are rectangular shaped panels, each having a flanged inner edge, a linear outer edge and opposite flanged side edges. The flanged inner edges of the stiles and the flanged side edges of the cross pieces are C-shaped, as illustrated in figures 4, 5 and 6. This configuration allows them to be resilient so that they may be forced by the restricted entrance of the longitudinal grooves of moldings 38, 40, 42, 44 into securement in these grooves.
25As can be seen in figure 3, the recesses of moldings 46 and 50 are in the form of longitudinal slots having a width adapted to receive the straight flanged inner edges 16a, 24a of the cross pieces 16 and 24 and portions 54a, 56a of frames 54, 56, respectively.
Frame 56 has a web portion 56b extending across the width of the door assembly and defining a stop wall for polyurethane foam 57 injected in the space defined by the spacers, the stiles, the cross pieces and the moldings to form an insulation for the assembly. Again when the door is fully assembled, as described hereinbelow, the free extremity of web 56b is squeezed between an inner projection 54b of frame 54 and the side wall of the molding 46. The frames 54 and 56 each have a longitudinal window contacting lip portion 54c, 56c, between which is secured the peripheral edge of the window unit 28.
It can be seen that, should it be required to remove the unit 28 from its opening, frame 54 is slid out of its engagement with the web 56b and the slotted recess of the molding 46.
To assemble the door assembly of the present invention, the metallic members 12, 14, 16 and 18 are placed within a first hollow rectangular assembling frame (not shown). The cross moldings 46 and 48 are properly positioned as well as the longitudinal moldings 38 and 21~369 40. Thereafter, the wood spacers 30, 32, 34 and 36 are placed thereover.
In a second hollow rectangular assembling frame (not shown), metallic members 20, 22, 24 and 26 are positioned and frame 56 placed thereover. This is followed by the installation of the cross moldings 50 and 52 and the longitudinal moldings 42 and 44.
Then, the second frame with its components is flipped over the first frame in a face-to-face arrangement. Thereafter, the assembly is pressed so that all the interconnecting edges may engage their corresponding recesses of the moldings. Finally, an injection of foam is made through a proper opening (not shown) in one of the wood spacers 30, 32, 34 and 36 so that the entire space defined between the various components is filled with insulation. The foam thereafter solidifies to form as rigid core that bonds the assembled components together. Hence, in this embodiment, no fastening devices are required for the assembly of the door.
The outer edges of the stiles have recesses 60, 62 (see figure 4) to receive the flanged outer edges 64, 66 of the stiles. The outer edges 68, 70 (see figure 3) of the cross-pieces terminate flush with the end wall 72 -` 2~3~3~9 of the cross spacers 34; the peripheral edges of the cross pieces may be glued to the wood spacers.
The above described door may be manufactured and assembled at the plant. However, if the window unit is assembled elsewhere, frame 54 is shipped separately with the other assembled parts to the window installation plant where a window unit is placed in the opening of the bonded door structure and secured therein by forcing the engaging parts of frame 54 to interconnect with the corresponding parts of the bonded door structure Referring to figures 7 and 8, a variant is illustrated; however, only those parts which are different from that of the embodiment illustrated in figures 1-6 will be described. The rectangular frame 156 lS includes a web portion lS6b which lies in contact over a web portion 146a of the molding 146. To further ensure bonding of the web portion 146a to the foam 57, a series of fastening elements 200 secures the web portions lS6b and 146a together (see figure 7). Similarly, molding 140 is modified to include a web portion 140a which lies under and contacts web portion 156b of frame 156, both being secured together by means of fastening elements 200 (see figures 8). These elements, however, are not visible in the assembled door. In this embodiment, the frame lS4 has an inner hook wall 160 that engages the 213~369 protruding edge 14Ob of the molding 140 and the protruding edge 146b of molding 146.
. Although the invention has been described above with respect with one specific form, it will be evident to a person skilled in the art that it may be modified and refined in various ways. It is therefore wished to have it understood that the present invention should not be limited in scope, except by the terms of the following claims.
an opposite second side consisting of a pair of opposite metallic stiles and upper and lower metallic cross pieces extending between these stiles;
the upper cross pieces of the first and second sides being spaced from the lower cross pieces of the first and second sides to define, between the stiles, a rectangular opening in the door; each stile and each cross piece having outer edges and flanged inner edges facing the opening; each cross piece including flanged side edges;

The upper cross pieces 16 and 24 are spaced from the lower cross pieces 18 and 26 to define, between themselves and the stiles, a rectangular opening in which is subsequently received a window unit 28, such as a single glass panel or a pair of guillotine-type windows.
A pair of non metallic stile spacers 30 and 32 are disposed at the periphery of the stiles terminating at the outer edges thereof. Also, a pair of non metallic cross spacers 34 and 36 are disposed at the periphery of the cross pieces terminating at the outer edges thereof.
A pair of opposite front stile moldings 38 and 40 extends along the inner edges of the stiles 12 and 14 while another pair of rear stile moldings 42 and 44 extends along the inner edges of the stiles 20 and 22.
A pair of opposite front cross moldings 46 and 48 extends along the inner edges of the cross pieces 16 and 18 while another pair of opposite rear cross moldings 50 and 52 extends along the inner edges of the opposite cross pieces 24 and 26. These moldings are made of resilient plastic material.
The door assembly 10 comprises also front and rear rectangular frames 54 and 56 to which is fixed the window unit 28 as explained hereinbelow. These frames are made of rigid plastic material.
213~369 _ Figures 3, 4 and 5 are cross sections at different areas of the door assembly of figure 1 when all the components shown in figure 2 are assembled. All moldings 38, 40, 42, 44, 46, 48, S0 and 52 are M-shaped in cross sections, each defining a pair of recesses.
However, it will be noted that the cross section of moldings 46 and 50 (figure 3) as well as that of moldings 48 and 52 is somewhat different from the cross section of moldings 40 and 44 (figures 4 and 5) and of moldings 38 10and 42. Indeed, moldings 46, 48, 50, 52 display a pair of slotted recesses while moldings 38, 40, 42, 44 display a pair of rectangular grooves having a restricted entrance.
As can be seen in figure 2, the longitudinal 15rectangular stiles 12, 14, 20 and 22 have flanged inner and outer edges while the cross pieces 16, 18, 24 and 26 are rectangular shaped panels, each having a flanged inner edge, a linear outer edge and opposite flanged side edges. The flanged inner edges of the stiles and the flanged side edges of the cross pieces are C-shaped, as illustrated in figures 4, 5 and 6. This configuration allows them to be resilient so that they may be forced by the restricted entrance of the longitudinal grooves of moldings 38, 40, 42, 44 into securement in these grooves.
