1. Field of the Invention
The present invention is directed to a pan tile for use in a roofing system wherein a plurality of pan tiles cover an underlying, supporting roof structure and are collectively oriented to support a plurality of exterior, exposed roof tiles thereon. Each pan tile includes a substantially planar base and oppositely disposed planar side segments cooperatively dimensioned, configured and structured to require a lesser number of both the exposed roof tiles and pan tiles being used to cover a given surface area of the underlying roof structure.
2. Description of the Related Art
In modern day construction, roof covering systems typically include an underlying, supporting deck or like support structure. This underlying support structure is covered by a water proof or leak resistant material that may take various forms. In addition, roofing tiles, shingles and like roof coverings are frequently arranged and secured in overlapping relation to one another so as to collectively overlie the roof deck or like underlying roof support structure. Further, the water resistant covering applied to the outer surface of the roof deck serves to secure the plurality of exterior roof tiles directly to the underlying support. Alternatively, other materials such as cement, polyurethane, “poly-foam”, etc. may be utilized to secure or fix an underlying layer of roof tiles, shingles, etc. directly to the outer water resistant layer. As such, a roofing system, as generally described above, facilitates a water resistant roofing assembly as well as an outer or exterior, aesthetically pleasing roof covering.
However, one constant and continuous area of concern is the structure and procedure utilized in the installation of a roofing system specifically including the roofing tiles or like roof covering materials. In typical fashion, roof tiles may include an underlying tile disposed in laterally adjacent relation to one another and arranged in longitudinally adjacent rows or columns, especially when the roofing system is applied to a slanted or sloped roof. Moreover, an outer array of roof tiles are disposed in overlapping, at least partially supported relation on the underlying tiles. As such, the underlying tiles and outer roof tiles make up the exposed covering of the roof deck or like underlying roofing support structure.
In known or conventional roofing systems of the type generally described above, it is recognized in the roofing industry that both time and labor associated with installation, as well as the material cost of both underlying tiles and outer, exposed roof tiles are significant and sometimes prohibitive. These costs are especially high when both the underlying tiles and roof tiles are formed of a highly desirable but relatively expensive ceramic material, which are typically hand made or otherwise manufactured to meet customized specifications.
Accordingly, there is a long recognized need in the roofing industry for a roofing system incorporating roofing materials which reduce the cost and time of installation, as well as reduce the cost of materials a frequently large number of roofing tiles. Such a proposed roofing system should incorporate a pan tile which is dimensioned, configured and structured so as to adequately and effectively cover the underlying roofing support structure while at the same time effectively support the exterior, overlying roof tiles. Moreover, a preferred pan tile could be machine made either from a ceramic or other appropriate material and dimensioned and configured to provide adequate support to the overlying roof tiles. At the same time such a newly proposed pan tile would require a significantly lesser number of both the pan tiles and the conventional roof tiles overlying the improved pan tiles.
Further, the versatility of the proposed pan tile could be such as to serve as an underlying support for a variety of different outer roof tiles specifically including, but not limited to, barrel tiles of the type which are commonly used on domestic dwellings, condominiums and industrial buildings of various styles and designs. Moreover, a roofing system incorporating the preferred and proposed pan tiles of the type described above, should be capable of being secured in overlying relation to the underlying support structure of the roof using any conventional manner including the use of roof installation connectors such as nails, screws, etc or even the more complex connecting wires, clips, or like connectors which facilitate adherence of roofing tiles during extremely high wind conditions. However, when a securing material such as cement, poly-foam, etc. is utilized with a roofing system incorporating a proposed and improved pan tile a significantly lesser amount of such material should be required thereby further increasing the savings in material costs.
The present invention is directed to a roofing system and more specifically to the structure of a pan tile, wherein a plurality of such pan tiles are dimensioned, configured and structured to be incorporated in a preferred roofing system. In use, a collection of pan tiles cover and confront a roof deck or underlying support structure of a roof and provide efficient support for exterior roof tiles. Moreover, each of the plurality of pan tiles may be produced by a machine and formed from ceramic or in certain preferred embodiments of the present invention, from a fiber glass or other type of appropriate material. The forming of the pan tiles from a fiber glass or other appropriate material has the benefit of a significant reduction in weight while not sacrificing strength or other desirable physical characteristics. The reduction in weight when using a fiber glass pan tile also results in less cost of installation at least to the extent of those costs associated with the transporting of the assemblage of roof tiles to the work site as well as the physically lifting of tiles onto the roof area. While the formation of the pan tiles from fiber glass based material may comprise one preferred embodiment, additional preferred embodiments comprise the inclusion of various types of organic material into the composition of the tile. Moreover, such organic material may be used in combination with appropriate resins such that an organic/resin combination material from which the pan tile is formed facilitates molding of the tile into the desired dimension and configuration.
The structuring of the pan tiles and their collective disposition over the underlying roof support is such as to effectively confront, overlie and protect the underlying support of the roof. At the same time a significantly lesser number of roof tiles are required in providing an aesthetically pleasing exterior, exposed roof covering. Accordingly the present invention is directed to a roofing system which may be produced and installed in a manner which accomplishes a reduction in the cost of material and labor when utilized.
More specifically, each of the pan tiles includes an elongated, substantially planar base, which may vary in dimension, dependent on the particular application of the roofing system with which the preferred pan tiles are utilized. Further, the base of each pan tile comprises oppositely disposed, spaced apart side segments extending angularly outward from the base. Each side segment extends along a different longitudinal periphery of the base and preferably includes a substantially planar shape or configuration. In a most preferred embodiment of the present invention, the side segments extend outwardly at a common, obtuse angle relative to the base. Therefore, the transverse dimension of the base at least partially defines the spacing between the side segments so as to facilitate efficient support of the exterior roof tiles. Accordingly, a greater than normal spacing is provided between the laterally adjacent roof tiles of the roofing system, resulting in less roof tiles being used.
Additional structural features of one or more preferred embodiments of the pan tile include the base preferably having a common transverse dimension along its length. However, the transverse dimensions of the opposite side segments are greater at a leading end of the pan tile and converge, substantially evenly, towards a trailing end of the pan tile. This structuring results in the leading end of the pan tile having an overall greater transverse dimension than the trailing end thereof, while the oppositely disposed side segments collectively comprise a converging configuration as they extend from the leading end to the trailing end of the pan tile.
In addition, in order to provide a preferred and/or predetermined collective array of the exterior, exposed roof tiles, typically in overlapping relation to one another, the leading end of the pan tile has a greater height dimension than the trailing end thereof. Such cooperative dimensioning and configuring of the various components of the pan tile facilitate longitudinally adjacent roof tiles being efficiently arranged in an overlapping relation to one another, as is common with roofing tiles having a barrel-type configuration, as well as other types and styles of pan tiles. Similarly, longitudinally adjacent roof tiles are arranged in rows or columns which are laterally spaced from one another such that the entire underlying support of the roofing structure is covered by the combination of pan tiles and roof tiles.
Accordingly, at least one distinct advantage provided by the unique structuring of the pan tile of the present invention is the ability to utilize a lesser number of the roof tiles, regardless of their style or shape by increasing the lateral spacing between the various rows or columns of longitudinally adjacent overlapping roof tiles. By way of example, in a typical installation of the roofing system of the present invention, a one hundred sq/ft surface area of a roof deck or like underlying roof support structure may typically include approximately 70 pan tiles, disposed in confronting relation with the outer surface of the underlying roof deck and approximately 60 exterior roof tiles disposed in overlying, supported relation on the pan tiles. In comparison, conventional roofing systems of the type incorporating barrel shaped underlying pan tiles and barrel shaped exposed roof tiles would require approximately 80 pan tiles and 80 exterior roof tiles. Therefore, utilizing the roofing system of the present invention would result in savings in material cost as well as installation time and labor through the elimination of approximately 10 pan tiles and 20 of the possibly more expensive exterior roof tiles, over a commonly sized surface area, if a conventional roofing system were utilized. It should be further noted that in known or conventional roofing systems both the pan tiles as well as the roof tiles are frequently hand made or otherwise customized. Proportional savings in the underlying securing material such as polyurethane, cement, poly-foam etc. would also add to the overall savings and efficiency of utilizing a roofing system which incorporated a plurality of pan tile dimensioned, configured and structured in accordance with one or more of the preferred embodiments of the present invention.
The present invention comprises yet another preferred embodiment wherein each or at least the majority of the pan tiles, are formed of a “plastic material”. As used herein, the referred to plastic material is capable of forming the pan tiles utilizing conventional or customized molding procedures. In addition, yet another preferred embodiment of the present invention comprises a fixed or preferably integral formation of a plurality of the pan tiles in an elongated, overlapping array. More specifically, the longitudinal array may be at least partially defined by the plurality of fixedly interconnected pan tiles having the trailing end of one pan tile overlapping or overlying the leading end of a next, longitudinally adjacent pan tile in the elongated array. Accordingly, the overlapping array, is described as being part of a roofing system wherein the overlapping array extends from the roof crest downwardly, such as when applied to a slanted roof structure. When practically applied in this manner, the aforementioned overlapping, longitudinal array of fixedly interconnected pan tiles have the aforementioned relative dispositions of the trailing end of at least each intermediate pan tile overlying the leading end of the next pan tile.
Similar to the preferred embodiment described above, the overall structural features of each of these pan tiles may be substantially equivalent to the extent of including an elongated base having a common transverse dimension and being integrally secured to two side segments along the opposite longitudinal peripheries of the base. Further, each of the side segments extend angularly outward from the corresponding periphery of the base at an obtuse angle or other appropriate, predetermined angle. As with the additional preferred embodiments described above, the leading end of each of the pan tiles may include a greater height and transverse dimension than the trailing end thereof. Also, the side segments may be collectively disposed in an at least partially converging orientation as they extend from the leading end towards the trailing end.
Moreover, in at least one embodiment the pan tiles further comprise predetermined surface treatments and/or structures associated with at least an undersurface of the base and possibly an inner surface of the base as well as one or both of the side segments. More specifically, the undersurface of the base may comprise a roughened, irregular surface configuration, which may be more specifically defined by a substantially unfinished undersurface comprising an exposure of the fiber particles or content, such as when the pan tiles are formed from fiber glass or other appropriate “moldable” materials, which may also be accurately described as being at least partially fibrous or particulate, as set forth herein.
In contrast, the surface treatment of the inner surface of the base has a predetermined, irregular surface configuration which may be more specifically defined by a particulate material being applied to or formed in the base. As such, the particulate material is disposed of various particles extending outwardly from the inner surface of the base, thereby defining the aforementioned irregular surface configuration. As will be described in greater detail hereinafter, the particulate material may be in the form of gravel, sand, rock or stone particles, etc. Also, the particulate material may have a much smaller dimensional structure or configuration such as having a granular consistency as is common with smaller, sand particles or the like.
As set forth above, one preferred embodiment of the present invention includes at least some of the plurality of pan tiles of an applied roofing system being formed of a plastic material having structural and operative characteristics which allow the material to be molded. Such plastic material may be in the form of a polymer or like composite material, which may be even more specifically defined as a fiber reinforced polymer. Further, the plastic material from which at least the majority of the pan tiles may be formed may be a glass reinforced plastic, commonly known as “fiber glass” in popular usage.
Yet additional one or more preferred embodiments of the present invention include the provision of a solar energy system incorporated in the one or more pan tiles and/or structural modifications thereof. More specifically, the solar energy system may comprise photovoltaic systems or assemblies structured to convert, at least in terms of a roof covering, sunlight into electricity. Applicable photovoltaic systems are typically made of a semi-conductive material such as silicon. As such, cells of photovoltaic material are put together to form a module and such formulated modules can be grouped together on roofs to form arrays which generate power to the corresponding building.
Generally, there are primarily two types of photovoltaic systems comprising a crystalline (mono and poly) system and an amorphous system. The crystalline system comprises an array of silicon wafers sandwiched between two layers of glass. These panels or other structures are heavy and must be attached to a roof using secure fastening or attachment assemblies including metal brackets, bracing, etc. In contrast the amorphous silicon photovoltaic systems are flexible and light weight and may be used with various roofing components and materials in the form of a thin film. As such, the amorphous silicon photovoltaic systems can be incorporated as a laminate into the various roofing components and are almost unnoticeable when viewing the roof. Both of the above noted types of photovoltaic technologies are generally equal in cost in terms of dollars per installed watt of power. However, more financial incentives are being offered by state authorities for the use of photovoltaic technologies. In addition, the energy policy act of 2005 provides a credit of generally about 30% of expenditures for the purchase of qualified of photovoltaic equipment generally up to a range of approximately $2,000.
Therefore, one or more preferred embodiments of the present invention may include a solar energy system comprising appropriate photovoltaic assemblies incorporated into the pan tile structures. This will result in the production of solar generated energy as an extremely advantageous feature of the present invention. By way of example, various predetermined surfaces of the pan tile may be covered by a thin, flexible film or laminate of the amorphous silicon photovoltaic components. Yet another example may comprise a structural combination of the crystalline photovoltaic technology into various parts of the pan tile of the present invention.
Yet another preferred embodiment of the present invention comprises a roofing assembly which incorporates many of the structural and operative features of the pan tile structures and system as described above and herein. More specifically, the roofing assembly, including its various components, is disposed in supported relation on an underlying support and includes a plurality of exposed roof tiles. The underlying support of the roofing assembly embodiment of this invention may be substantially as set forth above and/or include in certain additional structural modifications such as vegetation including non-combustible, lightweight growth medium material strips.
Moreover, the roofing assembly embodiment of the present invention includes a plurality of pan tiles including a base and two oppositely disposed side segments extending outwardly from the base at a common, obtuse angle or alternatively at other appropriate angles, as also set forth above. The base is disposed in confronting relation to the underlying support and may be preferably disposed in a plurality of vertically oriented, longitudinal arrays or rows arranged at a predetermined spacing from one another. Moreover, the plurality of rows will typically extend vertically from the upper crest or crown of the roof down towards the lower periphery thereof. The predetermined spacing existing between the adjacent rows of the plurality of pan tiles are sufficient to facilitate at least some of the plurality of roof tiles being concurrently disposed in overlying/overlapping relation to correspondingly disposed side segments of adjacent pan tiles which are associated with transversely adjacently ones of the plurality of rows.
In addition, the roofing assembly of the present invention may also include a solar energy system extending between at least some of the plurality of rows, such as in overlying relation to exposed surface portions of the base of the pan tiles associated with the solar energy system. In addition, the versatility of the roofing assembly of the present invention is further demonstrated by defining the solar energy system as an elongated, thin, flexible film, laminate or like structure of amorphous silicon photovoltaic components. As an alternative, the solar energy system may comprise a structural combination of crystalline photovoltaic technology into various parts of the associated pan tile, such as, but not limited to in overlying relation to the exposed surface of the base of the associated plurality of pan tiles. The distinguishing structural features between the crystalline voltaic technology and the flexible, amorphous silicon voltaic components are set forth in detail herein and hereinafter.
Further structural and operative features of the roofing assembly embodiment of the present invention include the provision of a heat dissipating assembly disposed in heat transferring relation to at least a plurality of pan tiles and, as set forth above, in heat transferring relation to the plurality of roof tiles as well as the area of the remainder of the underlying support and roof structure on which the roofing assembly is disposed. In more specific terms, the heat dissipating assembly comprises a conduit assembly having an elongated configuration and structured to define a path of fluid flow or path of travel of a heat dissipating fluid. The elongated conduit assembly may comprise substantially a single elongated conduit assembly or alternatively a plurality of elongated conduit segments connected in fluid communication with one another on an end-to-end basis. Moreover, the heat dissipating fluid may be in the form of water and/or potable water circulating through the length of the conduit assembly in heat absorbing relation to the pan tiles with which the conduit assembly are associated and with the under portion or area of the roofing tiles, as set forth in greater detail hereinafter. Further, the heat dissipating water may also be subsequently collected at a water supply and used domestically or commercially for the hot water needs of the building associated with the roofing assembly of the present invention.
To render the heat dissipating assembly more efficient, the roofing assembly of the present invention also includes a connecting assembly comprising a plurality of clips each formed from a metallic or other efficient heat transferring material. Each of the plurality of clips are disposed to concurrently engage or be connected to the conduit assembly and concurrently be connected to or mounted on associated ones of the plurality of pan tiles. Also in at least one structural modification of the preferred embodiment of the roofing assembly, the pan tiles are formed from a metallic or other efficient heat conductive or heat transferring material. As such, heat collected by the plurality of pan tiles, due to their exposure to the sun, will be effectively transferred through the clips to the conduit assembly and further the heat dissipating fluid or water passing through the conduit assembly. In order to initially facilitate the efficiency of the heat dissipating assembly, the conduit assembly is preferably formed from a “Pex” tubing, which facilitates the absorbing of heat from the pan tiles and/or connecting clips to the heat dissipating fluid passing through the conduit assembly.
Yet additional structural and operative features of the roofing assembly embodiment of the present invention include the provision of a stabilizing assembly. The stabilizing assembly is disposed between adjacently disposed pan tiles of adjacent rows of such pan tiles and may be further positioned to define or determine the predetermined spacing there between. As such, the stabilizing assembly comprises an elongated stabilizing member or plurality of cooperatively disposed or connected member segments connected or positioned in an end-to-end relation to one another. Moreover, different ones of the stabilizing members are disposed between adjacent ones of the plurality of pan tile rows. The transverse dimension of the stabilizing members will be such as to facilitate an appropriate predetermined spacing between the adjacent rows. As such this determination of the predetermined spacing facilitates the placement of the plurality of roof tiles in overlying/overlapping relation to the side segments of transversely adjacent ones of the plurality of pan tiles, as set forth above.
Therefore, the plurality of stabilizing members are disposed in substantially aligned relation beneath corresponding ones of the roof tiles and are thereby disposed and dimensioned to provide a stabilizing at least partially supporting affect on the roofing tiles. Accordingly, the stabilizing assembly provides additional stabilizing characteristics to both the pan tiles and the roofing tiles associated therewith. Such stabilizing characteristics may include the plurality of stabilizing members being connected, mounted or at least partially adhered to the pan tiles and/or under portion of the correspondingly disposed roofing tiles. As a result, the stabilizing members may be associated with an adhering material such as, but not limited to, a poly-foam material. The poly-foam material, which would be disposed in at least partially surrounding and/or engaging relation to the exterior surface of the stabilizing members, would thereby serve to adhere or interconnect the pan tiles, conduit assembly and/or roof tiles. Such a poly-foam or other adhering material would be disposed in the spaces and areas beneath the plurality of roof tiles in at least partially surrounding and/or engaging relation to the stabilizing members, pan tiles and conduit assembly. Accordingly, the exterior surface of the plurality of stabilizing members may also be structured to better contact or interact with the adhering material. In contrast, the positioning of the stabilizing members absent any type of adhering material may also be utilized and still provide stabilizing characteristics to the entire roofing assembly at least comprising the purity of pan tiles and the plurality of roof tiles. Such stabilizing characteristics will prevent or at least significantly restrict a lifting, removal or other damage including impact damage, during adverse weather conditions such as high wind conditions and/or roof repair, installation, etc.
These and other objects, features and advantages of the present invention will become clearer when the drawings as well as the detailed description are taken into consideration.
For a fuller understanding of the nature of the present invention, reference should be had to the following detailed description taken in connection with the accompanying drawings in which:
Like reference numerals refer to like parts throughout the several views of the drawings.
The present invention is directed to a pan tile, generally indicated as 10, of the type intended to be used on roofing installations, as well as a roofing system which incorporates a plurality of such pan tiles. As dimensioned, configured and structured the pan tile 10 of the various preferred embodiments of the present invention facilitates the installation of a preferred roofing system and in addition significantly reduces the cost factor of the materials utilized. Therefore the pan tile 10 and roofing system of the present invention overcomes many of the disadvantages and problems associated with known or conventional roofing systems and materials associated therewith.
More specifically, the pan tile 10 of the present invention may be produced or manufactured by a machine, rather than by hand, and may be formed of a ceramic material or other appropriate material which facilitates a reduction in the cost of the plurality of pan tiles utilized. As set forth in greater detail hereinafter, one additional preferred embodiment of the present invention comprises the pan tile being formed of a fiber glass material or other appropriate “moldable” materials including organic materials and/or organic/resin combination materials. Each of these appropriate materials may or may not include preferred surface treatments on predetermined surfaces thereof. Further, the plurality of pan tiles 10 incorporated in a roofing system are structured to facilitate a direct confronting relation with a roof deck 20 or like underlying support and an adhering composition associated therewith. Moreover, the plurality of pan tiles 10 are adaptive for use with a variety of different styles and types of roof tiles such as, but not limited to, barrel tiles 18 which in typical fashion are disposed in overlying relation to the underlying pan tiles. An additional advantage in the utilization of the pan tile 10, based in part on their dimension, configuration and overall structure, is the reduction in the number of the exterior roof tiles 18 which are required for use over a given surface area of the underlying roofing surface 20 being covered.
More specifically, and as represented in the accompanying Figures, at least one preferred embodiment of the pan tile of the present invention is generally indicated as 10 and comprises a base 12 having an elongated configuration and being integrally secured to two side segments 14 and 16. Each of the side segments 14 and 16 preferably extend along the entire length of the base 12 and extend outwardly from opposite peripheral sides or edges 14′ and 16′ of the base 12 in a predetermined angular orientation. Further, each of the side segments 14 and 16 extend outwardly from the base 12 at a substantially common, obtuse angle so as to facilitate cooperative positioning and support of spaced apart, laterally adjacent roof tiles 18 as clearly represented in
Additional structural features of each of the pan tiles 10 include the side segments 14 and 16 collectively comprising a substantially converging configuration, as the side segments 14 and 16 of each pan tile 10 extend from the leading end 22 to and towards the trailing end 24 and preferably along the entire length of the base 12. Accordingly, the leading end 22 of each of the pan tiles 10 comprises a greater height dimension than that of the trailing end 24. Such a variance in height from the leading end 22 to the trailing end 24 is preferably accomplished by a progressively decreasing transverse dimension or height of the side segments 14 and 16 as they extend continuously from the leading end 22 to the trailing end 24, as represented in
However, yet another preferred embodiment of the pan tile 10′″ of the present invention is represented in

It should be further noted that a variation of the preferred embodiment of
Yet additional structural features of a most preferred embodiment of the present invention comprises each or at least the majority of the pan tiles 10 having a leading end generally indicated as 22 and a trailing end generally indicated as 24. For purposes of clarity the leading end 22 of each of the plurality of pan tiles 10 is disposed substantially “above” the trailing end 24, such as when the plurality of pan tiles 10 are incorporated within a roofing system secured to a sloped or slanted underlying roofing support 20, as is common. Also common to the overall array of both pan tiles and exterior roof tiles is their overlapping orientation or arrangement to longitudinally adjacent tiles, as generally indicated in

The relative positions and/or orientations of the pan tiles 10, 10′, 10″, etc. is such that a greater spacing will be created between the laterally adjacent roof tiles 18, 18′, 18″, etc. due to the overall structure of each of the respective pan tiles 10, 10′, 10″, having a flat or planar configuration of the respective bases 12. Also additional stability is provided by the confronting relation or engagement of the flat undersurface 12′ or the grooved undersurface 12″ with the exposed surface portion of the underlying roofing support structure 20. As such, the entire exposed outer surface area of the underlying support 20 will be adequately and appropriately covered by the roofing system as demonstrated in

With primary reference to
By way of example, when applied in the manner schematically represented in
As set forth above, the various embodiments of the present invention including individual pan tiles 110 or a linear, longitudinal array 130 of fixedly interconnected ones of such pan tiles can be formed from a variety of materials including ceramic material, fiber glass, other moldable plastic or resin materials and/or an organic based material which may be used independently of or in combination with a resin. Accordingly, in at least one preferred embodiment the materials from which the pan tiles 10, 110 and/or longitudinal array 130 of such pan tiles may be formed should be moldable so as to facilitate the manufacture and production thereof. Further, when fiber glass, organic based and/or organic/resin materials are utilized, sufficient strength is provided to the formed pan tiles while having the additional advantage of significantly reduced weight, which in turn reduces the overall cost factor at least in terms of transportation, installation, etc.
Moreover, and with primary reference to
The overlapping configuration of the longitudinal array 130 may be more specifically defined by a trailing end 124 of tiles 110′ being disposed in overlying relation with a next successive, longitudinally adjacent tile 110″. Therefore, the fixed interconnection between the longitudinally adjacent pan tiles 110, etc. may be accomplished by an integral bonding. As such, the plurality of pan tiles 110 defining the overlapping, longitudinal array, as represented in

Further, the adding or provision of the particulate material 120 may be accomplished during the molding process of the fiber glass or other appropriate organic or combined organic/plastic materials from which the plurality of pan tiles 110 are formed. In doing so, the particulate material 120 will be integrally formed in the pan tiles 110 so as to extend at least partially outwardly from the specifically indicated surfaces 112″ and/or 114″ and/or 116″. As such, the application of the particulate material 120 to one or more inner surfaces 112″, 114″ and 116″ has the benefit further facilitating the securement or adherence of the roof tiles 18 to the various inner surfaces of the supporting pan tiles 110 as represented in
In yet another preferred embodiment, such as that represented in

More specifically, the roofing assembly 200 comprises a plurality of pan tiles 202 which may be disposed in a substantially longitudinally elongated arrays or rows 203 having a predetermined spacing there between. As represented in
As also represented throughout the
Further with regard to the provision of a solar energy system 212, the photovoltaic system may be secured to the exposed surface of the base 204, as at 204′ by means of an adhesive structural or material 207, represented in
Yet additional features of the roofing assembly 200 of the present invention include a heat dissipating assembly generally indicated as 214 in
In at least one embodiment, the transverse segment 216′ may extend beneath corresponding pan tiles 202 such as at the junction 204. As set forth above, the junction 204 may have a stepped and/or channeled configuration and/or be otherwise articulated so as to facilitate the placement of the transverse segment 216′. It should be further apparent that the disposition of each of the plurality of pan tiles 202 relative to the underlying support 220 should be such as to facilitate the placement of the transverse segment 216′ beneath other portions of the corresponding pan tiles 202, other than the junction 204.
With primary reference to
It is emphasized that the terms “heat conductive” or “heat transferring” is used to describe a material, structure, etc. which has sufficient heat conductive characteristics to serve as an effective “heat sink”, at least to the extent of dissipating heat from pan tiles and/or surrounding areas. Accordingly, the pan tiles 202, clips 226, conduit assembly 216 are sufficiently heat conductive to cause the effective and intended degree of heat dissipation through the plurality of clips 226 and conduit assembly 216 and the flowing, circulating heat dissipating fluid or water flowing through the conduit assembly 216.
As a result of the effective operation of the heat dissipating assembly 214, the heat transferred to the heat dissipating fluid, in the form of water, retains sufficient heat to be useful. More specifically, as schematically represented in
Yet another feature of the present invention comprises the provision of a stabilizing assembly 230 as represented in
The stabilizing assembly 230 of the present invention may also include appropriate adhering material 21 such as adhesives or a foam material including poly-foam as described above with reference to
In order to facilitate adherence or interaction between the adhering material 21, be it poly-foam or other adhesive, the exterior surface of the various stabilizing members 232 can be structured such as being channeled or being formed somewhat irregularly, as at 232′. Therefore, the provision of the stabilizing assembly 230 at least in the form of the stabilizing members or structures 232 will add overall stability to the roofing assembly and restrict damage thereto such as by lift forces being applied to the exposed roof tiles 210 and/or damage caused by impact on the roof tiles 210.
Yet another structural and operative feature associated with the roofing tile assembly 200 is the provision of vegetation 240 by which may be disposed between the adjacently disposed rows of the roof tiles 210. Also, the vegetation 240 may be placed in overlying relation to the exposed surface of the base of associated pan tiles or between the plurality of rows of roof tiles 210 associated with different but transversely adjacent rows of pan tiles. Moreover, the vegetation 240 may be in the form of vegetated mats utilizing rock wool strips or other non-combustible, lightweight growth medium to facilitate the nutrition of the vegetation 240. In addition, while not specifically represented, the vegetation 240 and/or the system associated therewith may include a drip system secured to an appropriate part of the roof or roof assembly 200 and operative to supply sufficient water and other nutrients to the vegetation 240.
Since many modifications, variations and changes in detail can be made to the described preferred embodiment of the invention, it is intended that all matters in the foregoing description and shown in the accompanying drawings be interpreted as illustrative and not in a limiting sense. Thus, the scope of the invention should be determined by the appended claims and their legal equivalents.
