DETAILED DESCRIPTIONS OF THE PREFERRED EMBODIMENTS
Referring now to the drawings in detail, reference is first made to FIG. 1, wherein a panel generally designated 10 of this invention is illustrated. The panel 10 includes a base layer 11 of a molded synthetic polymeric building material that is adapted to be weather-protected in the installed condition on a building structure, and a layer 12 of asphalt based building material.
The layer 11, of polymeric material may be comprised of the thermoplastic material disclosed in U.S. Pat. Nos. 6,808,785; 7,351,462; 7,141,200; 7,141,201, as representative of polymeric materials.
The layer 12 of asphalt based building material may be constructed in accordance with the detailed description of FIG. 6 hereof, for example, or of laminates of materials of the type of FIG. 6, or a material of the type described with reference to FIG. 6 having an additional overlay of adhesive and granules applied to a surface thereof, as representative constructions for the layer 12 of asphalt based building materials.
The polymeric 11 layer of building material may be provided with cut-outs or voids, recesses or the like 13, such as are illustrated in FIGS. 2 and 3, outlined by peripheral ribs 14, 15, 16 and 17, and supported by interior ribs 18, 20, 22 and 23, for providing rigidity to the panel 10, as well as support, so that, for example, in the event that a panel 10 is installed on a roof or the like, installers will be able to safely walk on an exterior surface 24 thereof, without collapsing the panel 10.
The asphalt based building material 12 may be comprised of upper and lower courses 25 and 26 of individual shingles or tiles or portions thereof, with adjacent such individual tabs of shingles or tiles being separated by actual or simulated slots 28 that are generally vertical and spaced apart from each other, to give the overall appearance of a plurality of courses of individual tabs of shingles or tiles 27. In the case of actual slots, the upper surface 30 of the polymeric layer 11 will be exposed and visible through the slots 28. Such exposed portions of the polymeric layer 11 are appropriately stabilized to the environment. In the case of simulated slots, defined by generally vertical lines appearing on the upper surface 24 of the asphalt based layer 12 and on a lower edge of the asphalt based layer 12 as shown in FIG. 2, the lines 28, 32 that define the simulated slots will appear only as aesthetic markings.
As shown in FIG. 1, the right-most edge 33 of the asphalt based layer 12 overlies the right-most edge 34 of the layer of polymeric building material and the lowermost edge 35 of the asphalt based building material layer 12 protrudes below the lowermost edge 36 of the layer of polymeric building material, so that the right edge of the panel 10 as illustrated in FIG. 1 can be in lapped relation with a left-most edge of a next adjacent, substantially identical panel to that 10 of FIG. 1, which adjacent panel is not shown in the illustration of FIG. 1. Similarly, when the panel 10 of FIG. 1 has its lower edge disposed against a next-subjacent panel (not shown), the overlying edge 35 of the asphalt based panel 12 will overly a portion of a layer of polymeric building material of a next-subjacent panel that is similarly constructed to the construction of the panel 10 of FIG. 1.
Thus, the left-most edge 37 of the layer of polymeric building material 11 protrudes beyond the left-most edge 38 of the asphalt based layer 12 of material, and the upper edge 40 of the layer of polymeric building material 11, likewise protrudes above the uppermost 41 of the layer 12 of asphalt based building material, as illustrated in FIG. 1.
It will thus be seen that when panels of the type 10 of FIG. 1 are applied to a surface of a building structure (not shown), next laterally adjacent panels will be in lapped relation to each other, as will be vertically adjacent such panels 10 be in lapped relation to each other.
One or more photovoltaic panel portions 42 may optionally be provided on selected tabs of the upper surface 24 of the asphalt based layer 12 of building material, for capturing photovoltaic energy when the panel 10 is installed on an exterior surface of a building structure, and the photovoltaic panel portions 42 may be provided with wires 43, passing through holes 44 in the panel layers 11, 12, for transmitting photovoltaic energy through panels 10, as illustrated in FIG. 3.
With reference to FIG. 3A, it will be seen that a pair of panels 10 and 10′ are shown, with the panel 10′ being subjacent to the panel 10, in lapped relation as described above, and wherein wires 43 and 43′ for forming the electrical connections between photovoltaic panel portions 42 and 42′ for the panels 10 and 10′, are connected to each other, passing through the layers 11 and 12 and 11′, 12′ of respective panels 10 and 10′ at 44 and 44′, respectively.
Wire connection devices are provided, for connecting wires 43 and 43′ of various panels such as 10 and 10′ to each other, from panel-to-panel via connectors 45, in the form of male and female connector elements 46, 47, respectively, for connecting together wires such as those 43, 43′ of a pair of panels such as 10, 10′ to each other, as shown in FIG. 3B.
At the upper left corner of the illustration of FIG. 1, there is provided a temperature sensor 50, more clearly shown in the detail illustration of FIG. 1A, which temperature sensor 50 is subject to expansion and contraction as a function of temperature, as is the panel, and which sensor provides a visual indication thereon, in the form of the gradations 51 of thermal expansion and contraction characteristics of the panel 10, at a given ambient temperature of the panel 10. For example, the temperature sensor 50 may be constructed in accordance with the disclosure of U.S. Pat. No. 6,939,036, the complete disclosure of which is herein incorporated by reference.
With reference now to FIG. 4, it will be seen that a fragmentary portion of a roof or siding structure 59 is illustrated for a building structure, and wherein a panel 51 in accordance with this invention is illustrated. The panel 51 includes a base layer 52 of synthetic, polymeric material, having a plurality of courses 53, 54 of asphalt based building material thereon, shown in edge view in the illustration of FIG. 4. The base layer of synthetic polymeric material is provided with two generally flat portions 56, 57, disposed at acute angles to the surface 58 of the structure 50, offset relative to each other as illustrated at 60, and wherein the portions 56, 57 of the synthetic polymeric layer are each provided with a lip 61, 62 protruding in a generally transverse direction relative to flat portions 56, 57, to engage and support lower ends 63, 64, respectively, of the asphalt based shingles or tiles 53, 54 thereagainst.
With reference to FIG. 5, similar components and portions of components to those illustrated in FIG. 4 are identified by the numbers 51′, 52′, 53′, 54′, 55′, 56′, 57′, 58′, 59′, 60′, 61′, 62′, 63′ and 64′, except that the lips 61′ and 62′ are in underlying relation to lowermost respective edges 63′ and 64′ of the asphalt based shingle or tile layers 53′, 54′ seating the shingles or tiles 53′, 54′ against the flat portions 56′, 57′ of the synthetic polymeric based building material 52′.
The lips 61, 62 and 61′, 62′ can be eliminated to yield a shingle appearance and structure like that addressed hereinafter for the shingle of FIG. 29.
Referring now to FIG. 6, there is illustrated a transverse sectional view, taken through a layer of asphalt based building material 70 in accordance with this invention. The material 70 is comprised of a layer of mat 71, which can either be of organic or inorganic construction, but which will preferably be of inorganic construction, generally comprised of a cross-weave of fiberglass strands 72, 73, impregnated with a bituminous material, such as asphalt 74, having an adhesive 75 on an upper surface thereof, which adhesive may also be an asphaltic based (bituminous) adhesive and may or may not comprise the same adhesive material that is the asphaltic material 74, and with a layer of granules 76 on an upper surface thereof, adhered thereto, by the adhesive 75. An adhesive 79 will generally be provided on a lower surface of the mat 71, which adhesive 79 may or may not be the same as the asphalt based adhesive 74. The adhesive 79 will be provided with a layer of fine particles 77 on a lower surface thereof as shown at FIG. 6, which fine particles may be of sand or mica construction or of any other suitable material, which layer of particles 77 will generally be comprised of smaller particles than the granules 76 that appear on the upper surface of the asphalt based building material 70.
With reference to FIG. 7, a pair of adjacent panels 80, 80′ of this invention are provided, each of which has a base layer 81 or 81′ of synthetic polymeric building material and an overlying layer 82 or 82′ of asphalt based building material, constructed similarly to that illustrated in FIG. 3A, for example, but wherein adjacent edges 83, 83′ of the base layers 81, 81′, are lapped in interlocked relation with each other, as shown, and with an edge portion 84 of the asphalt based layer 82 of building material, overlapping a portion 84′ of the layer 81′ of polymeric based building material. It will be understood that the lapping and interlocking relationship shown in FIG. 7 and as described above can take place between right and left laterally adjacent panels in accordance with this invention, or between vertically adjacent panels in accordance with this invention, or both.
With reference now to FIG. 8, panels 90, 90′ in accordance with this invention are illustrated, having similar components to those illustrated in FIG. 7, having synthetic polymeric base layers 91, 91′, with asphalt based layers 92, 92′ of building materials, with interlocking edges 93, 93′ as shown, that differ from the configuration of interlocked edges 83, 83′ illustrated in FIG. 7, and wherein the asphalt based layer 92 has an end 94 overlapped with an underlying end 94′ of the base layer 91′, as shown, with the illustration of FIG. 8 being otherwise similar to the illustration of FIG. 7 discussed above.
With reference now to FIG. 9, a fragmentary cross section of an alternative panel 100 in accordance with this invention, is illustrated. The panel 100 comprises a pair of base layers of molded synthetic polymeric building material 101 and 102, connected together by an adhesive layer 103. A pair of asphalt based building material layers 104 and 105 are provided, each of which is constructed like the asphalt based building material 70 of FIG. 6, and they are connected together by an adhesive layer 106, with the synthetic polymeric building material layer 101 and the asphalt based building material layer 105 being connected by an adhesive layer 107. Beneath the synthetic polymeric building material layer 102 there is provided a layer 108 of insulation material, preferably a foam type insulation, although the same could be a fiberglass based insulation or made of other insulating materials. The left end 110 of the panel 100 would normally be the end that is the lowermost, generally horizontal edge of the panel 100 when the panel is installed on a building structure. In order to cover the left edge of the insulation layer 108, the left-most end 111 of the polymeric layer 102 covers the edge 112 of the insulation layer, so that the insulation layer's lower edge 112 is not visible from below, when the panel 100 is installed on a building structure, with the end 110 being the lower vertical edge thereof.
FIGS. 10 through 16 are different right edge views of layers of molded synthetic polymeric building material as would be seen by looking at the right edge of each item of building material 120a, 120b, 120c, 120d, 120e, 120f, and 120g if their flat surfaces 121a, 121b, 121c, 121d, 121e, 121f and 121g were to be installed on an exterior surface of a building structure, leaving their left-most surfaces of various different configurations to have layers of asphalt based building material disposed thereagainst (not shown) and to be the weather-exposed layers of building material, leaving the polymeric building material layers 120a, 120b, 120c, 120d, 120e, 120f, and 120g to be the weather-protected layers of building material, and wherein the layers of polymeric building material illustrated in FIGS. 10-16 would be vertically mounted on a building structure (not shown), with their lowermost edges 123a, 123b, 123c, 123d, 123e, 123f or 123g being the vertical lowermost edges when mounted on a building structure. Thus, the molded synthetic polymeric building materials, right edge illustrations of which are indicated in FIGS. 10 through 16 present differently configured layers of polymeric building material, adapted to supports layers of asphalt based building material on their outermost surfaces 122a, 122b, 122c, 122d, 122e, 122f or 122g when installed on a building structure.

Further, in the case of embodiments such as that depicted in FIG. 24, the lateral offset may be selected such that the passages 203 through 208 align with similar such passages of panels of a subjacent or superjacent course.
In FIG. 25 there is illustrated a sectional view of a panel 140, of the type of FIG. 18 comprising an asphalt based panel layer 143 overlying an upper synthetic polymeric panel layer 141, secured thereto, which panel layer 141 overlies another synthetic polymeric layer 142 having recesses 145 therein, and peripheral and interior ribs 146, 147, with right and left edges of the polymeric layer 141 terminating at right and left edges of the peripheral ribs 146, as illustrated.
Similar components to those described above for the illustration of FIG. 25, are correspondingly numbered as 140′, 141′, 142′, 143′, 144′, 145′, 146′ and 147′ in the embodiment of FIG. 26. It will be noted that the polymeric panel layers 141′ and 142′ are likewise secured together, as are comparable panel layers for the embodiment of FIG. 25. The polymeric layers 141 and 142 can be adhesive secured together or heat laminated or co-extruded, so that they are secured together.
In the embodiment of FIG. 26, depending transverse portions 148′ and 149′ of the polymeric layer 141′ cover peripheral ribs 146′ of the polymeric layer 142′, to provide an alternative panel edge configuration.
FIG. 27 illustrates another panel 210 in accordance with this invention. The panel 210 includes a base layer of polymeric building material 211, having two courses 212 and 213 each comprised of double layers of asphalt based building material 214, 215 and 216, 217, the layer 214 being adhesively secured to the layer 215, and corresponding layers 216 and 217, also of asphalt based building material, with the layer 216 overlying and being adhesively secured to the layer 217.
It will be noted that the layer 215 has a lower edge 218 that protrudes outwardly, extending lower than the edge 220 of the layer 214, in a petticoat effect.
Similar to the course 214, the lower asphalt based layer 217 has a lower edge 221 that protrudes outwardly below the lower edge 222 of the layer 216, also in a petticoat effect. Slots 223 and 224 appear in layers 214 and 216, such that the upwardly facing surfaces of layers 215 and 217 will be visible through the slots 223 and 224. If the upper surfaces of asphalt based layers 215 and 217 are darker than the upper surfaces of the layers 214 and 216, such darkness will appear not only through the slots 223 and 224, but also at the lower edges 218 and 221 having the petticoat effect, in order to produce a visual contrast for the two asphalt based courses 212 and 213. Additionally, notches 225 and 226 may appear throughout the several layers, as shown, at the lower ends of the slots 223 and 224, with the notches 225 and 226 being present not only in the upper asphalt based layers 214 and 216, but preferably in all layers illustrated in FIG. 27.
In the fragmentary illustration of FIG. 28, the panel 230 is comprised of an upper asphalt based layer 231 and a lower polymeric layer 232. In this embodiment, the polymeric layer 232 has its lower edge 233 protruding out past the lower edge 234 of the asphalt based upper layer, also producing a petticoat effect. In the embodiment of FIG. 28, the upper surface 235 of the polymeric layer 232 may, if desired, be of a darker shading than the upper surface 236 of the asphalt based layer 231, to produce a contrast not only with the petticoat effect described above, but also to provide a darker contrast through the slots 237 in the upper asphalt based layer 231. In the instance where portions of the polymeric layer 232 are to be exposed to the elements, it will be understood that suitable stabilizer packages may be incorporated into the surface layer(s) of the polymeric layer 232.
In FIG. 29, there is illustrated a synthetic polymeric base layer 250 for the panel 251, and a pair of asphalt based layers 252 and 253, as shown, with an edge portion 254 of layer 252 overlying an edge portion 255 of layer 253. As indicated in the enlarged detail view of FIG. 29A, to the left of edge 252 there is provided a shadow line effect 256, comprised of a band of adhesive to the left of edge 254, securing to the upper surface of layer 253 a band of granules thereon. Typically, the shadow line 256 produced by the band of granules will be comprised of granules that are darker than any granules that appear on the upper surfaces of the layers 252 and 253. It will also be understood that the panel 251 of FIG. 29 is shown as a right side view of a panel, that would normally be installed on a building structure, with panel edge 257 being vertically located above the opposite edge 258, with the edge 258 thereby being a lower edge when the panel 251 is installed on a vertical surface of a building structure, or on a sloped roof of a building structure. It will also be understood that a shadow effect 256 may also be accomplished by local deposition of a stripe of darker granules in the location of the desired shadow line during manufacture of the asphalt based layer 70 of FIG. 6.
FIG. 30 illustrates in fragmentary view, a panel 260 in accordance with this invention, wherein the panels base layer 261 is of polymeric building material, and is provided with a plurality of planes 262, 263, 264, 265, 266, for example, that have different angular relations to each other, to produce a staggered, or random effect, and that asphalt based layer components, 267, 268, 270, 271 and 272 are disposed thereover, again adhesively secured thereto, to give a random-appearing effect simulating natural cedar shake, slate, or tile effects.
In the exploded view of FIG. 31 there is illustrated a plurality of layers that comprise a building panel 280 in accordance with this invention, such layers comprising lowermost polymeric layer 281 adhesively secured beneath polymeric layer 282, by an adhesive 283. The polymeric layer 282 is secured beneath an asphalt based layer 284 by means of an adhesive 285. The upper surface 286 of asphalt based layer 284, shown with a plurality of dots thereon, is intended to show, as a drafting expedient, that the surface 286 may be generally of a uniform darker appearance, such that, when it is adhered beneath uppermost asphalt based layer 287, the darker surface 286 will be visible through the slots 288 and 290 in the courses 291, 292 of shingles, tiles or the like that comprise the asphalt based layer 287. It will be seen that the lower edges 293 of the shingles or tiles in course 291 overly the upper edges 294 of shingles or tiles that comprise the course 292. Both courses 291 and 292 of shingles or tiles are adhesively secured to the asphalt based layer 284, by an adhesive 295.
With reference to FIG. 32, it will be seen that a building structure 300 is provided, with a roof 301, an end wall 302 and a sidewall 303. A panel 304 in accordance with any of the embodiments in accordance with this invention is disclosed positioned on the sloped surface of the roof 301, although the panel 304 could equally well be located vertically, on the surface 303 or 302 of the building structure 300. It will also be understood that a plurality of such panels would be used, preferably with overlapping edges, to cover the entirety of the roof 301 and/or the entirety of one or more sidewalls 303 or end walls 302, as will be understood from all of the foregoing.
Shingles in accordance with this invention, wherein an asphalt based layer overlies at least a major portion of a polymeric layer, leaving exposed some portion(s) of the polymeric layer, may be made to emulate any of a wide range of shingle appearances or aesthetics as disclosed in the illustrations herein, or which are well known in the roofing art, such as but not limited to those of U.S. Pat. Nos. 6,038,826; 6,044,608; 6,205.734; 6,467,235; 6,523,316; and 6,920,730, the complete disclosures of which are herein incorporated by reference.
It will also be understood that when shingle panels in accordance with this invention are applied to a roof, either in the same course or in subjacent or superjacent courses, such adjacent, subjacent or superjacent panels can have portions of their left or right sides and/or top and/or bottom edges offset from each other, or such sides or edges can be at any of selected diagonal orientations, or in shiplapped or interlocked relation to next adjacent, subjacent or superjacent panels.
