[0003] Patio enclosures and sunrooms are not new to the building industry.
When adding onto or remodeling an existing home or other structure, many people turn to the patio enclosure or sunroom. Such rooms are relatively easy for trained technicians to construct and are inexpensive when compared to other improvements that can be made to a home, such as remodeled bathrooms or kitchens. These enclosures have traditionally been constructed of an aluminum frame with windows or glass sections. Aluminum sunrooms are shaped with vertical walls that have a curved transition to the roof, although most may have a marquee roof or gable type roof.

Such rooms are relatively easy for trained technicians to construct and are inexpensive when compared to other improvements that can be made to a home, such as remodeled bathrooms or kitchens. These enclosures have traditionally been constructed of an aluminum frame with windows or glass sections. Aluminum sunrooms are shaped with vertical walls that have a curved transition to the roof, although most may have a marquee roof or gable type roof.
[0004] The following United States Patents and Patent Publication illustrate various enclosures, non-metallic structural elements used in constructing these enclosures, and the materials used in forming the non-metallic structural elements: 5,497,594 to Guiseppe et al.;

[0005] As discussed in Schneider US-6,003,279 and US-6,460,309, aluminum framed enclosures have several disadvantages. The main problem is poor thermal efficiency. Due to the high rate at which aluminum conducts heat, a room constructed from aluminum cannot stay comfortably cool in the summer, without air conditioning, or warm in the winter, without supplemental heating. This drawback results in dramatically increased cooling and heating costs. Further, a high rate of heat transfer can lead to condensation on the interior surfaces of the aluminum structures. Moreover, many of the windows in aluminum frame type sunrooms are generally installed in such a way that the windows cannot be opened and no screens are present.
[0006] Another disadvantage is high maintenance. Aluminum must be painted if chipped and is easily dented. Construction of aluminum rooms is a major disadvantage as well. Because of the nature of the metal, the aluminum pieces must be assembled with external fasteners. External fasteners increase the time of assembly and degrade the overall aesthetics of the room.

[0007] In light of these various deficiencies, Schneider US-6,003,279 discloses various structural members, which include reinforced and non-reinforced polyvinyl chloride extrusions, which are joined together at joints using hardware which cannot be seen from inside or outside the enclosure, thereby enhancing the aesthetic appeal of the enclosure.
Further, Conn US-5,848,512 and Schneider US-6,460,309 disclose an I-beam that is extruded from plastic and configured such that the vertical spacer wall defines a central passageway that extends between the opposite ends of the beam. Schneider US-6,460,309 is directed to a vinyl roofing system utilizing the channel beam to interconnect roof panels with a roof cap.

[0008] In obviating certain of the problems associated with unwanted condensation and thermal conductivity, many framing enclosure designs have used a "sleeve"
approach wherein the aluminum elements and sections are enclosed within PVC frames. A
drawback to this approach is that the aluminum reinforcing still has to be properly insulated from the rest of the vinyl profile. This approach results in massive, bulky sections with high material costs.

[0009) A need continues for a low maintenance sunroom/patio enclosure that is economical, has improved thermal efficiency and minimizes thermal condensation arising from thermal transmittance, provides sliding or double hung windows and/or doorway, has an aesthetic appearance, conceals connecting fasteners, and employs fastening components that are easy to use when erecting the enclosure.
[00010] Accordingly, a primary object of this invention is the provision of a sunroom/patio enclosure that obtains the benefits of framing elements and sections of polymeric and like material, and achieves the above noted needs.
[00011 ] Another object of this invention is the provision of a sunroom/patio enclosure using frame elements formed of composite PVC to allow parts to have smaller cross-sections without a great degree of internal reinforcing.
[00012] As is known, steel has much lower conductivity to thermal loss than aluminum, and has higher strength properties with lower cost.
[00013] Accordingly, another object of this invention is the elimination of most if not all aluminum components from the enclosure product, such as by replacing some frame connecting elements with galvanized steel.
[00014] Another object of this invention is the provision of an enclosure structure that shows no screw heads on the inside or the outside of the enclosure room.
[0001 SJ A further object of this invention is the provision of an enclosure structure comprised of composite PVC to combine the properties of wood with the maintenance free advantages of vinyl.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[00048] Referring to FIGS I and 2 - 4 there is shown an exemplary patio enclosure, generally indicated at 10, constructed according to the present invention. The enclosure 10 is supported from below by a load-bearing substrate 12 and laterally by the exterior wall 14 of II
an existing structure, such as a house (not shown). The load bearing substrate 12 may be a concrete slab, wood decking, or the like.
[00049) As shown in FIG. 1, the enclosure 10 comprises a front wall 16, a pair of lateral side walls 18 and 20, and a sloping roof 22. The walls 16, 18 and 20 project upwardly from the substrate 12 where they are joined to the roof 22. The sidewalls 18 and 20 have opposite lateral ends connected, respectively, to the house and a respective lateral end of the front wall 16.
[00050] The walls and roof of the enclosure 10 are formed by a framework of joined horizontal and vertical structwal members, such as structural filler wall panels 24 and roof panels 26, multiple pairs of sliding glass windows 28, framed screens 30 for each pair of windows (one shown), and an optional conventional door assembly 32.
[00051 ] Each wall panel 24 is generally rectangularly shaped and has a central body 24a of polymeric material, such as foam, and outer layers 24b and 24c wherein to provide a wall panel element of generally uniform thickness. The thickness of the wall panel 24 is such that the lateral edges thereof may be interFtted into the squared-C channel of a structural element according to this invention (described in detail below). Preferably, both of the layers 24b and 24c are clad with vinyl.
[00052] Preferably and according to this invention, certain of the structural elements used in this assembly are shown and identified on FIGS. IA - lE. These structural elements include a corner post 34, a post or H-beam 36, a base track 38, a cross-beam channel 40, and a filler 44. As will be discussed below, nails, screws and like threaded fasteners, flanges and like connecting elements are used to connect the structural elements together and form modular wall portions and the patio enclosure 10.
[00053] Preferably and according to this invention, each of these structural elements are comprised of a composite PVC material and extruded into the desired cross-section and length. Subsequent to extrusion, a vinyl surface is clad to the exterior surfaces of the structural elements. The resulting element is sometimes referred to a composite PVC
element. The structural elements made from the composite PVC material are generally stronger than wood, metal, or vinyl, has no adverse heat conduction, and has the durability of vinyl. Although extrusion is a preferable method, these elements may be injection molded.
[00054] According to one aspect, the composite material is comprised of a bound together mixture of cellulosic material (esp. sawdust or like finely pulverized dried wood, such as wood flour) and baking flour (e.g., the fine powdery foodstuff obtained by grinding and sifting the meal of a grain, especially wheat, used chiefly in baking).
Suitable woods for sawdust are resin-free softwoods such as pine, fir and spruce, and to a lesser extent, hardwoods. The percentage of sawdust to baking flour, measured by weight or volume, and a binder and/or mixer ingredient used to hold the composition together is determined, in part, on a cross-section property of the structural element that is desired (i.e., thickness and area moment of inertia of the cross-section).
[00055] Referring to FIG. IA, the corner post 34 is box-like, in cross-section, axially elongated, and formed by walls 46, 48, 50 and 52.

[00065] A wall panel 24 is inserted downwardly into the opposed squared-C
channels of successive H-beams 36 or corner post 34 and H-beam 36. As can be seen in FIG. 5, the protective outer layers 24b and 24c of the panel 24 are generally coextensive (i.e., flush) with the outward extension of the flanges 62 and 64 of the H-beam 36.
[00066] The upper track 38b forms a closure cap and support for a forward lower front end of the roof structure 22. To provide support and sealing, an axially elongated, generally cylindrical strand 94 of elastomeric material is supported atop the upper track 38b, on the extended base portion 74 thereof, and supports and moisture seals the roof structure 22 of the enclosure 10.
[00067] As shown in FIG. 6, a cross-beam channel 40 is interfitted onto and supported atop the upper lateral horizontally extending edge of the wall panel 24.
Further, window framing 28 is thereafter supported atop the cross-beam channel 40.
[00068] As shown in FIG. 7, a cross-beam channel 40 is inte~tted onto the lower lateral horizontally extending edge of the wall panel 24.

[00074] Further and according to this invention, the cross-sections of a filler 44 and the central track 73 of a base track 38 are such that the filler 44 forms, with the central track 73, a closure that makes the two elements appear as one unitary structure. The interfitment between the outer legs 84 and 88 of the filler 44 and the interior facing ends of the L-shaped arms 70 and 72 of the base track 38 results in a snug snap-fit frictional interengagement.
[00075] As shown in FIG. 12, a base track 38 is threadably fastened to the exterior wall 14 and the vertical lateral edge of a wall panel 24 is interfitted within the track 73 formed between the opposed L-shaped arms 70 and 72 of the base track 38.

[00077] As shown in FIG. 14, a corner post 34 connects the vertical edges of the left and front walls 18 and 20. The corner post 34 extends vertically upwardly from the substrate 12 and is connected to two base tracks 38a, the base tracks extending horizontally along the substrate and at right angles to one another. The two base tracks 38a are connected to the substrate 12 by L-shaped flanges 90 in a manner described above. One L-shaped flange 90 is disposed in one base track 38a and has a vertical leg 90a received in the squared-C channel 56 and threadably fastened to the wall 48 of the corner post beam. The other L-shaped flange 90 is disposed in the other base track 38a and has a vertical leg 90a received in the squared-C
channel 58 and threadably fastened to the wall SO of the corner post beam.
[00078] An E-shaped filler beam 44 is snugly interfitted within the squared-C
channels 56 and 58 wherein to provide the corner post 34 with a clean aesthetic appearance.
[00079] As shown in FIG. I, the roof 22 is generally rectangularly shaped, angles downwardly from the exterior wall 14, and is generally coextensive with the front and side walls 16, 18 and 20 of the enclosure 10. The roof structure includes severally generally rectangularly shaped roof panels 26, a rearward channel bracket 98, a forward channel bracket 100, left and right end brackets 102 and 104, and a plurality of H-beams 36. The roof panels 26 are as described for the wall panels 24. Further, the channels 98 and 100 and end brackets 102 and 104 are comprised of a composite PVC, as described herein above.
[00080] The rearward channel bracket 98 is mounted to the exterior wall 14 and has an outwardly open channel 98a adapted to receive rearward lateral edges of the roof panels 26 and rearward end portions of the H-beams 36.

[00063] The upper track 38b forms the upward vertical extension of the front wall 24 and is secured, at least in part, to the upward vertical extension of the H-beam 36. As with the track 38a, the upper track 38b is provided with positioning flanges 90.
[00064] The lower and upper ends 36a and 36b of the H-beam 36 are nested into a respective track 73 formed between the opposed L-shaped arms of each respective track 38a and 38b. So positioned by the flanges 90 secured to the lower and upper tracks 38a and 38b, the flange leg 90b extending upwardly from the lower track 38a is threadably secured to the lower end portion of the H-beam, and the flange leg 90b extending downwardly from the upper track 38b is threadably secured to the upper end portion of the H-beam.
[00065] A wall panel 24 is inserted downwardly into the opposed squared-C
channels of successive H-beams 36 or corner post 34 and H-beam 36. As can be seen in FIG. 5, the protective outer layers 24b and 24c of the panel 24 are generally coextensive (i.e., flush) with the outward extension of the flanges 62 and 64 of the H-beam 36.
[00066] The upper track 38b forms a closure cap and support for a forward lower front end of the roof structure 22. To provide support and sealing, an axially elongated, generally cylindrical strand 94 of elastomeric material is supported atop the upper track 38b, on the extended base portion 74 thereof, and supports and moisture seals the roof structure 22 of the enclosure 10.
[00067] As shown in FIG. 6, a cross-beam channel 40 is interfitted onto and supported atop the upper lateral horizontally extending edge of the wall panel 24.
Further, window framing 28 is thereafter supported atop the cross-beam channel 40.

[00074] Further and according to this invention, the cross-sections of a filler 44 and the central track 73 of a base track 38 are such that the filler 44 forms, with the central track 73, a closure that makes the two elements appear as one unitary structure. The interfitment between the outer legs 84 and 88 of the filler 44 and the interior facing ends of the L-shaped arms 70 and 72 of the base track 38 results in a snug snap-fit frictional interengagement.
[00075] As shown in FIG. 12, a base track 38 is threadably fastened to the exterior wall 14 and the vertical lateral edge of a wall panel 24 is interfitted within the track 73 formed between the opposed L-shaped arms 70 and 72 of the base track 38.
[00076] As shown in FIG. 13, a base track 38, a wall panel 24, and -a cross-beam channel 40 extend vertically upwardly from their connection to a horizontally extending lower base track (not shown). The opposite lateral vertically disposed edges of the wall panel 24 are interfitted within the central track 73 and squared-C channel 80 formed by the vertically disposed base track 38 and cross-beam channel 40. A flange 90 positions and secures the lower end of the cross-beam channel 40 relative to the lower base track. Further, the cross-beam channel 40 positions associated window framing 28.
[00077] As shown in FIG. 14, a corner post 34 connects the vertical edges of the left and front walls 18 and 20. The corner post 34 extends vertically upwardly from the substrate 12 and is connected to two base tracks 38a, the base tracks extending horizontally along the substrate and at right angles to one another. The two base tracks 38a are connected to the substrate 12 by L-shaped flanges 90 in a manner described above. One L-shaped flange 90 is disposed in one base track 38a and has a vertical leg 90a received in the squared-C channel 56 and threadably fastened to the wall 48 of the corner post beam. The other L-shaped flange 90 is disposed in the other base track 38a and has a vertical leg 90a received in the squared-C
channel 58 and threadably fastened to the wall SO of the corner post beam.
[00078] An E-shaped filler beam 44 is snugly interfitted within the squared-C
channels 56 and 58 wherein to provide the corner post 34 with a clean aesthetic appearance.
[00079] As shown in FIG. I, the roof 22 is generally rectangularly shaped, angles downwardly from the exterior wall 14, and is generally coextensive with the front and side walls 16, 18 and 20 of the enclosure 10.
