Description
- Doors made of synthetic materials have become common place in the construction industry for both residential and commercial buildings. Such products are durable, stable and often include a wood graining on the surfaces to give these doors the appearance of natural wooden doors. Such characteristics are desirable to owners, builders and architects.
- EP-A-0 359 906 discloses a frame assembly for doors, windows and the like. In particular the assembly includes a frame defining an opening for receiving and retaining a central panel. The frame is formed of two joined skins, which may be molded in the same mold and which are provided with inwardly extending flanges having notched areas on opposite sides of the flanges such that the skins can be joined together to form a lap joint on the exterior edge and to seal a central panel in the opening. Foamable insulating material is provided as a core between the two skins with a separate sealant material provided to seal the central panel. Passage means are provided for introducing the sealant material and the insulating material.
- US 5,644,870 discloses a door being formed from two rectangular compression molded skins, with each skin having inside surface and an outside surface and on its inside surface a plurality of projecting, parallel ribs along at least two of its edges, a hinge support having a plurality of grooves on its opposite sides with the grooves operable to interlock with the ribs on the skins along one side of the door when the skins are assembled with this support and an accessory support having a plurality of grooves on its opposite sides operable to interlock the ribs of the skins along the other side of the door when the skins are assembled therewith wherein no frame is required for the door when a foamed in place polyurethane core is formed between the skins. The door uses interlocking members at its side and top edges and a preformed bottom panel or insert.
- US 5,887,398 discloses a synthetic door casement being composed of multiple panels of L-shaped compression molded skin panels which are joined with batten means on their inner surfaces to form a pair of opposed rectangular casement skins which casement skins are then joined on opposite sides of an outer frame surrounding an inner frame to form a hollow rectangular casement which is then filled with a plastic foam. The inner frame has an external recess to receive a glass pane along with cooperative retention moldings to hold the pane in place in the recess of the inner frame once the pane is inserted therein. As described with reference to figures 5 to 9, the L-shaped skin panels are assembled with an outer frame composed of a vertical stile, which is positioned to engage a bottom rail and a top rail. Furthermore, the site opposed this stile is a matching vertical stile. In order to obtain sufficient strength of the door casement the integral edges are essential.
- Popular synthetic door structures are those constructed of sheet molded resins reinforced with fiber glass, such as disclosed in U. S. Patent 5,644,870 issued to Chen describing the construction of one of these type of doors. In addition there a number of patents assigned to Therma-Tru Corporation which taught this same type of construction, e.g., see U. S. Letters Patent 4,550,540 issued to Thorn. The sheet molding compounds (SMCs) employed are molding resins which include unsaturated polyesters resinous compositions, such as those defined in U. S. Letters Patent Nos. 3,772,241 issued to Kroexel and U. S. Letters Patent No. 3,884,612 issued to Ivor Pratt et al, which are typically reinforced with fiberglass before molding. Such compositions are processed, by the well known sheet molding processes, into thin sheets or skins.
- Other patents describing the use of compression molded sheets in door structures, include U.S. Patent No. 4,901,493, U.S. Patent No. 4,860,512, U.S. Patent No. 4,864,789 and U.S. Pat. No. 4,965,030 all issued to Thorn, along with U.S. Patent No. 5,142,835 issued to Mrocca and U.S. Patent No. 5,075,059 issued to Croon.
- According to the reference patents, as well as other patents, the sheets or skins employed to construct such doors are made by a sheet molding process wherein uncured resins, reinforced with fiber glass, are compressed between large molds, using pressure and heat, to form thin sheets or skins having a thickness from 0.05 inches to 0.120 inches. While the sheets formed by such process are strong, and can be embossed with wood graining on their outside surfaces, they remain quite flexible in the plane normal to their surfaces. For this reason, and others, to construct a door with these skins, it is often necessary that they be mounted on a rectangular stick frame by gluing them to the assembled frame and filling the resulting hollow space between the skins and the frame with a plastic foam, such as polyurethane foam which is foamed in place. The frame and foam cooperate with the skins glued to the frame to increase the rigidity of the door structure normal to the plane of the surface of the skins. Moreover the skins provide more than adequate integrity to the plane of the surface of the skins for the lightweight door structures described in the prior art.
- While the designs described are satisfactory for doors without large lights (windows) and for doors with small lights, the described construction has been found less that satisfactory for doors with large lights, which are often referred to as patio doors, due to the heavy loadings induced on the frame from the weight of the glass of the tights.
- With today's environmental concerns, patio doors often have double glazing (two panes of glass separated by a small space filled with a gas) which requires a frame supporting such double glazing to carry very substantial loadings. In fact some building codes require such double glazing.
- It can be appreciated that the thin skins, when required to carry the weight of such glazing, can buckle under such loadings if the door frame constructed of these skins is not properly designed. Further, the glue used to bond the skins to the stick frame is placed under tremendous sheer loadings which can rip the skins from the frame if the design does not distribute the loading properly.
- It is an object of the present invention, among others, to design a door structure employing thin compression molded skins as a frame for patio doors, and like, which will accommodate the loadings involved and provide an extended service life for the door frame.
- Another object is to provide better weather integrity for patio doors which are constructed in door frames formed with thin skins of compression molded panels by making the area around the window light or pane completely water tight.
- Still another object of the invention is to provide a design for such a patio door which better distributes the loadings to the skins forming the exterior components of the door frame.
- Also it is an object to provide an integral flange in one of the skins making up the frame to support one face of the light or pane, along with a removable interlocking glazing strip, to lock the light or pane in the resulting door frame.
- The above objects and many oilier advantages can be obtained with an improved frame for supporting a large window light or pane in door frames constructed of synthetic materials and leaving an integral glazing frame for retaining the light or pane includes a first skin of a compression molded sheet material, the first skin having an aperture with a first integral edge strip oriented generally normal to the plane of the first skin and extending from and around such aperture, a second skin (and opposing skin) of a compression molded sheet material, the second skin having an aperture with a second integral edge strip oriented generally normal to the plane of the second skin and extending from and around such aperture, interlocking means formed on the edge strips operable to fixedly to join said edge strips of the two skins in a permanent overlapping relationship when glue is applied to the surfaces of the interlocking means, a glazing frame means associated with the edge strips having an integral extending flange projecting from one of the edge strips and a glazing strip operable to retain a window light between the flange and the glazing strip when said the edge strips are fixedly joined by the interlocking means, a perimeter frame means closing the space between the skins about their outer perimeter fixedly joined to the respective skins on opposite sides of the frame means and operable to form a hollow space between the frame means and the interior surfaces of the joined edge strips, and a formed in place foam core in said hollow space.
- The defined objects of this invention, along with other advantages can be accomplished by employing the structures illustrated in the following drawings, wherein:
- Fig. 1 is a plan view of the novel patio door frame constructed according to the teachings of this invention;

-
- The novel
patio door structure 20, shown in Fig. 1 includes two principal components, thedoor frame 21 and the window light orpane 22. The light or pane is typically formed of two glass sheets separated by small perimeter divider, with void between them preferably filled with a gas, and their edges sealed together to form a unit. Such units in a typically sized patio door (121,9 cm x 243,88 cm) ((4' x 8')) can weigh in the range of 45,36 kg (100 pounds). - As can be seen in Figs. 1, 2 and 3, when the light or
pane 22 is inserted into thedoor frame 21 and the entire weight of the pane is supported by the frame which includes compositevertical stiles 23 and a composite tophorizontal rail 24 along with a composite bottomhorizontal rail 25. In Fig. 2 the cross-section of the vertical stiles is illustrated with the similar cross section of the bottom horizontal rail illustrated in Fig. 3. - Referring to Figs. 2 and 3, it can be seen that the
skins vertical stile post 32 in Fig 2 andhorizontal rail member 38 in Fig. 3 at their outer peripheral edges. The top rail member is identical to the stile posts in cross section and therefore is not shown. The inner peripheral edges of these skins around thecentral aperture 26 include integral edges.Skin 30 has anintegral edge strip 34 incorporating an extending an upstanding flange 35 (with its axis oriented generally parallel to the surface of the associated skin) andskin 31 has anintegral edge strip 36 has with extendingrim 37. As described in U. S. Letters Patent No 5,644,870 integral edge strips similar to the of the type used in the current invention can be constructed with interlocking elements. A permanent joint between these strips can be effected with glue. Here theedge strips door frame 21 about the central aperture, as distinguished from the outer perimeter of the skins as shown in the '870 patent. These edge strips are designed to be interlocking structures as shown in Figs. 4 and 5. - The wall thickness of edge strips 34 and 36 is increased from the thickness of its associated skin (about 0,127 cm (0.05 inches) to 0,318 cm (0.12 inches)) to the range of 1,27 cm (0.5 inches).
Edge strip 34 has agroove 40 formed therein so that arib 41 at the distal end ofedge strip 36 will be received in this groove when the opposed skins are assembled providing an interlocking relationship. Typically these edge strips are joined with glue on their contiguous surfaces when interlocked with one another as shown in Fig. 5. - When the two
skins glazing frame 60, withrib 41 ofstrip 36 received in thegroove 40 ofstrip 34 and glue is applied to appropriate surfaces of the edge strips 34 and 36 before joining skins together. Such interlocking edge structures form a closed, hollow space between the skins and at the same time, double the wall thickness of the structure in the glazing frame to increases its strength. - Unique to
current door frame 21 is that theflange 35 and theapron 42 ofedge strip 34, having surfaces at right angles to one another, form part a theglazing frame 60 designed to receive the light orpane 22. In this regard the extending flange has a light orpane abutment face 43, typically grooved to enhance its sealing capacity against the light or pane. A light or pane inserted into the glazing frame abuts againstface 43. When this interface is effected the bottom edge of a light or pane is supported principally by the apron of edge strips of thebottom rail 25. Moreover, sinceedge strip 36 ofskin 31 underlays the apron (see Figs. 2, 3 and 5), increasing the thickness of the structure supporting the light or pane in the glazing frame, increased strength in this area is obtained which is where such strength is desired. A further advantage is achieved in that the skin, flange and apron are integral with one another, a single unit, resulting in a weather tight structure when the edge strips of the several skins are glued together in the described interlocking relationship. - Next since the compression molding process can achieve substantial detail,
edge strip 34 ofsheet 30 can include alip 44 at its distal end 45 formed during the compression molding process (see Fig. 5); however this lip, requiring some precession, can also be machined at the distal end of this edge if necessary. Whenedge strip 36 is joined with edge strip 34 agroove 46 is formed between the distal end 45 ofedge strip 34 and the extendingrun 37 ofedge strip 36, as illustrated in Fig. 5, showing the resulting joint in greater detail. - Referring to Figs. 2 and 3 it can be appreciated an
extruded glazing strip 47 having a profile as illustrated in Fig. 4 and Fig. 6 can be employed in thegroove 46 to retain a light orpane 22 12 previously inserted into thedoor frame 21. In this regard the glazing strip has anupper section 48 that is generally triangular in cross section, a cross section (best shown in Fig. 5) which is similar in cross section to the cross section to theintegral flange 35 ofedge strip 34, and, as can be seen in Figs 2 and 3, when glazing strip is assembled in the groove the exterior appearances of the glazing strip and the flange on opposite sides of the light or pane appear similar. In Fig. 6 it can be seen, thebottom section 49 of the glazing strip is designed to be received in thegroove 46 and includes ashoulder 50 which abuts on the top of the extendingrim 37 ofedge strip 36 to stabilize glazing strip and plugportion 51 which is actually received in thegroove 46. This plug portion terminates in anangular tip 52 which, when the plug portion is received in the groove, extends under thelip 44 at the distal end 45 ofedge strip 34 to lock the glazing strip in the groove. - The
upper portion 48 of theglazing strip 47 is designed to deflect slightly due to its reduced cross section (see Fig. 6) when itsplug portion 51 is pushed intogroove 46, forcing theangular tip 52 underlip 44 to lock the strip in place. Further its light orpane engaging face 53 is grooved to form two sealing faces 54 and 55. A vinyl orrubber seal strip 56 is shown associated with the pane engaging face of the strip in Fig. 6 and is employed to improve the seal against the light orpane 22 when it is retained by theglazing strip 47. If desired additional seal strips can be employed on this face, as illustrated in Figs. 2 and 3. This arrangement allows the glazing strip to be popped out ofgroove 46 to replace the light or pane, if necessary. - It can be appreciated from the forgoing description that glazing frame 60 (a frame for receiving a window light or pane) is formed by the described edge strips which is completely water tight and strong enough to support the heavy dual glass panes now in use. Further since the edge strips 34 and 36 are formed integrally with
skins pane 22 on theapron 42 on the bottom glazing frame is distributed uniformly to the skins forming the exterior surfaces ofdoor frame 21. - Once the
skins peripheral edges 61 of the skins are joined at their perimeter to the stile posts 32 by gluing the skins to these posts with the top peripheral edges 62 of the skins joined to thetop rail member 33, also with glue. Likewise the bottomperipheral edges 63 of the skins are joined with thebottom rail member 38 in the same manner (see Fig. 7). When this procedure is completed stile posts and rail members form a perimeter frame closing the outer edges of thedoor frame 21 leaving ahollow space 64 between the interior of theglazing frame 60 and the interior surfaces of these members. - In Fig. 7 the interior structure of the
door frame 21 can be seen beforeskin 31 is assembled withskin 30, illustrating the positions of the stile posts 32 and rails 33 and 38. If desired,filler members 65 can be glued to the central portion of the stile posts (as illustrated in Fig. 7) and to the skins to provide support for door hardware or accessories, such as latching mechanisms and locks (not shown). - Again referring to Fig. 7, once
skin 31 is assembled with the structure illustrated therein, the door frame is not yet complete. The final step is to introduce a plastic foam, such as polyurethane foam, into the resultinghollow space 64. This can be accomplished by drilling a small hole in thetop rail 33 member and injecting foaming agents into this hollow space to create afoam core 66. Polyurethane 15 compositions have the advantage that they can be foamed by CFC-free materials and produce gases which do not harm the Ozone layer. Moreover, halogen-free materials are also better flame retardant, making polyurethane foams the foam of choice for thecurrent door frame 21. Also polyurethane foams have better insulating qualities and better acoustical absorption characteristics, plus a history a satisfactory performance in such structures. When the foam agents are introduced into the hollow space in the frame, the resultingfoam core 66 fills the entire space, bonding to the skins, the stile posts and the rails, marrying these parts together as a composite unit. - While it is preferred that the
skins door frame 21 constructed with such composite skins. When such composite skins are employed, it may be desirable, in larger frames, to employ an inner rectangular frame or additional stiles of wood or steel which abut 16 against interior surfaces of theglazing frame 60 to increase its strength. Of course, it is an option to use such additional reinforcement adjacent to the interior of the glazing frame, even when single panel skins are employed. - The stile posts 32 and the
rail members door frame 21 or the utility of the resulting door frame. In the regard the stile posts 32 and thetop rail member 33, they can be constructed of wood, metal and plastic extrusions. Normally the sides of these members which engage the inner surfaces of the skins havegrooves 69 which allow any excess glue to flow into the grooves, forming a glue ridge in the groove that increases the shear strength between the skin and the stile posts and the top rail member. In addition stile posts can includevertical stops 70 which theperipheral edges 61 of theskins extensions 71 which extend beyond thestops 70 allowing a carpenter to trim top and side edges of thedoor frame 21 to fit into a door opening. - The
bottom rail member 38, while constructed of the same materials as the stile posts 32, is somewhat different in that it is often required to perform additional functions and is subject to extensive trimming to accommodate differences in the opening in which the door frame is installed. In this regard, as shown in Fig. 3, this rail member is usually equipped with two large, spaced apart grooves 72 which are quite deep. As a result even after extensive trimming, the grooves are still available to receive a bottom weather strip 73 shown in Fig. 8. Typically the weather strips has ribs that can be pushed into the grooves to retain it in place across the bottom of the door frame. - In addition the
bottom rail member 38 can be routed from the bottom to remove, in part, the portion 74 of tins this member between the grooves 72 so that recessed roller assemblies 75 can be inserted in the bottom of the door frame, as shown in Fig. 9. - In most cases the exterior surfaces of the
