Description

The present invention relates roofing systems roofing outer coverings and corresponding energy gathering or producing means and more particularly, to battens used in roof construction and improved tile fixing means.


A problem of prior art in the field is the extended time necessary for workers operating in an elevated and potentially dangerous environment to manually affix battens and mounting or fixing means to attach or secure surface coverings including energy gathering surfaces to a roof.


BACKGROUND AND SUMMARY OF THE INVENTION

Any discussion of the prior art throughout this specification should in no way be considered as an admission that such prior art is widely known or forms part of common general knowledge in the field.


A roof structure having an outer layer or roof covering consisting one or more of a tiles or slates or panel or sheet or roof plane outer surface, hereinafter referred to as roof coverings or tiles, may advantageously have at least one area provided with or containing or covered with or supporting a means of gathering or producing energy including an electric current; said sheets or tiles or panels may include multiple layers of said means of gathering or producing energy. Such Roof Coverings are often manually handled into convenient groups ready to affix to the proximate roof structure elements including rafters and said roof structure elements hereinafter referred to as rafter or rafters.


As part of the process of fixing the Roof Coverings in place one or more skilled persons working in situ on the roof structure will normally also need to precisely position and apply or fix to the Rafters a means of restraining or holding said roof coverings in place on a roof structure, including the placement and fixing of load bearing battens hereinafter referred to as Support battens to support said roof coverings and the precise placement of a holding means or restraining means to removably or otherwise fix or retain tiles on the roof structure.


The present invention includes the provision of a means to connect roof coverings to a roof structure preferably including but not limited to a clip made of any suitable material including metal treated to provide a spring effect and having a means to fixingly and or removably hold or restrain or attach preferably in close proximity to at least one edge of one of said roof coverings in a desired position on Support battens and said means to connect roof coverings to a roof structure hereinafter referred to as metal clip and preferably said metal clip also providing a means of removably and or fixingly engaging with lightweight battens of any suitable material but preferably of metal such as in U.S. Pat. Nos. 7,454,873 and 7,448,177 McClintick which patents are hereby incorporated by reference in this application; said lightweight battens being not structural in the sense that they are not designed to bear roof load but instead are provided to conveniently fixingly and or removably anchor said metal clips in a precise and consistent alignment and said lightweight battens, or at least said metal clips being further affixed in a precise location on support battens. Said support batten when fixed in place on other structural elements of the roof frame such as rafters also transfers load carried by said support batten to said other structural elements of the roof frame such as rafters. The said support battens together with one or more metal clip or one or more of said lightweight battens affixed thereto may advantageously and preferably be assembled other than on a roof so that the said assembly, hereinafter referred to as the Support batten assembly, can be handled on a roof essentially like any structural batten to be affixed to the structure of a roof by efficient means as is commonly done by tradespersons applying such structural Support Battens to roofs. The advantage of a Support batten assembly is that it provides multiple precisely aligned metal clips to engage and affix roof coverings in a corresponding precise alignment thereby avoiding the need for tradespersons in situ on the roof to spend the time necessary to apply with precision at least a multiplicity of restraining means for roof coverings to elements of a roof structure.


Said support battens and support batten assemblys preferably also being of precise dimension and or having locational dimensions at least in relation to the width dimension measured in the direction parallel to the slope of the roof from eave to a roof ridge. Said dimensions or measurements referred to in this paragraph and hereinafter are measured with reference to normal in situ position on a roof structure. Advantageously the present invention also provides for a system and device to assist with roofing generally and in one specific instance to aid fixing precise location of each row of said support batten assemblys on said rafters in positions extending from the eave to the roof ridge; for example, starting from a first support batten assembly fixed on rafters in a desired position adjacent to a roof eave so as to set the position of the first or eave row of tiles and others of said support batten assembly located between the eave and the ridge of a roof, a first spacer piece or spacer device of appropriate material and dimension may advantageously be placed, at least temporarily, abutting the edge one or more rafters and the said first support batten assembly at the edge closest to the ridge-line of the roof hereinafter referred to as the Upper edge; said first spacer piece having a dimension between its Upper edge and corresponding lower edge such that when a second Support batten assembly is placed parallel to the first Support batten assembly and abutting one or more rafters and also abutting the Upper Edge of said first spacer piece, the desired gauge or spacing may be achieved between said Support batten Assemblies thus also achieving the desired gauge or spacing of roof coverings such as rows of slates or tiles which are affixed to said Support batten assemblies. Others of said spacer pieces and Support batten assemblies may be similarly placed in position to achieve the desired location of each row of roof coverings from roof eave to roof ridge. The gauge function of said spacer pieces in establishing the desired spacing apart of Support batten assemblies may also be performed by a device hereinafter referred to as Gauge Device which abuts or engages with one or more of Support batten assembly and Rafter. A Gauge Device may advantageously be adjustable to easily provide desired different spacings of Support batten assemblies.


Said Support Battens used to produce the said Support batten assemblies and spacer pieces or gauges may advantageously be formed from any suitable material preferably sourced from a renewable resource and including timber preferably being plywood and preferably from plywood having a water-resistant outer layer; and the locating and affixing of the Support battens in relation to the rafters by use of spacer pieces in the aforesaid manner provides a simple and easily verifiable means of correctly setting out the necessary “gauge” or vertical spacing of the Support batten assemblies so that each row of roof coverings such as tiles or slates will be correctly positioned; and if the said spacer pieces are constructed to be the same length and thickness as the said Support battens and permanently fixed in position there is additionally provided a contiguous surface covering rafters from eave to ridge which has superior load bearing to that provided by Support Battens alone. Such said contiguous surface covering rafters is advantageous in areas receiving additional loadings such as snowfall on roof coverings and is also useful in improving retention of tiles on a roof structure during extreme weather events when the air pressure acting on the outer surface of a tiled roof may at least temporarily become less than the air pressure within the building such that the higher air pressure within a building acts upon the contiguous undersurface of said support battens and spacer pieces before it can act on the underside of said roof tiles or roof sheets forming said outer layer of a roof structure and thus aiding in resisting the propensity of individual roof tiles to be dislodged in certain weather conditions.


Preferably said support battens and spacer pieces may be manufactured of a material available from sources having a minimal environmental impact and preferably from a sustainable re-growth harvesting source such bamboo or woodlot timber and said Support battens and spacer pieces may also be advantageously produced with abutting long edges shaped to co-operatively abut and engage so that when Support battens are fixed to the rafters of a roof structure said spacer piece is locked into position against the rafters between abutting support battens and thereby firmly retained without the need to have said spacer piece fixed to said rafters by mechanical separate fixings. Alternatively, said spacer pieces may also be fixed to said rafters by mechanical fixings similar to said Support battens so as to increase the holding force retaining the said Support battens and spacer pieces on said rafters.


Said roof covering or outer layer may for example also include; sheets or panels or tiles including those constructed of any suitable material or combination of materials including metals and plastics or glass, preferably including fiber reinforced cement or concrete, supporting on the surface, a solar energy or ambient heat harvesting means or a means of heating, as a coating on said tiles or surrounding one or more cell or layers of cells on or inset into and partially covering the surface of said tiles; including cells formed of one or more layers of elements or combinations or compounds or mixtures of said elements in the Periodic Table of Elements. Said Periodic Table of Elements may be seen at http://www.vertex42.com/ExcelTemplates/periodic-table-of-elements.html and which is by reference incorporated in this application.


Presentations by Robert Murray-Smith have been made since about 2011 concerning materials and methods which may be employed in the manufacture of devices suitable for the harvesting of solar and ambient energy layers of elements or combinations or compounds or mixtures of said elements in the Periodic Table of Elements including Carbon in graphene form as well as other materials including plastics and polymers, acids, alkalis and commercially available materials employed in making materials which may be employing in the manufacture of cells suitable for the harvesting of solar and ambient energy and said presentations were made by way of videos filed at https://www.youtube.com/user/RobertMurraySmith/videos?view=0&live view=500&flow=list&sort=dd and the videos listed there are by reference in their entirety included in this application and following by way of example are references for some but not all of the videos hereby incorporated in this application.

Said means of producing conducting or transmitting the electricity may include one or more layers or coatings on said tiles or sheets; a strip or extrusion of metal or plastic including flexible plastics having one or more thin layers of, or having channels containing, one or more thin layers of electrical conducting material; said electrical conducting material including one or more elements from the Periodic Table of Elements and including preferably Carbon C as a graphene or a form thereof and or graphite and or graphene intercalated with one or more substance formed from the constituents of the periodic table of elements or compounds thereof and more preferably from the group including Nickel, Copper, Tin, Fluorine, Sodium, Chlorine; said strip or extrusion may also advantageously have integrally formed on or attached to the edges a means of sealingly joining said edges or by employing known means to join said edges to form a tube or shaped conduit suitable as a means to transmit or conduct electricity with less resistance than copper wires; said means of conducting or transmitting electric current may also include tubes or nano tubes of materials including carbon having an inner surface coated and or annealed or otherwise treated or coated.


In another exemplar of the present invention a means of harvesting the energy in ambient heat in or in close proximity to a roof surface is provided by replacing at least partially the “Slate Liner 140 ”, referred to in U.S. Pat. No. 7,454,873 McClintick in FIG. 7 and elsewhere in the said US Patent, with a similar dimensioned liner comprising or having one or more of its surfaces at least substantially covered with one or more layers of elements from the Periodic Table of Elements or combinations or compounds of said Elements and said replacement liner disposed with a collection means so that energy can be obtained from ambient heat similar to the disclosures referred to in U.S. Pat. No. 6,103,054; alternatively said liner replacement of said Slate Liner 140 may be a more robust liner with increased resistance to UV and other degrading influences by the combination or lamination of a more resistant layer together with a layer of polymer such as high density polyethylene HDPE; said more resistant layer preferably being a metal such as stainless steel or at least a substance highly resistant to degradation by UV radiation or at least highly resistant to degradation by natural processes over effluxion of an extended time period consistent with the expected longevity of a traditional slate roof which may exceed 100 years of useful service.


The present invention includes a system whereby, after fixing of Support Batten Assemblies and or spacer pieces to Rafters of a roof frame structure, groups of roof coverings including roof tiles or slates are be conveyed to the roof structure by means of a crane or other lifting means in discrete groups placed conveniently in quantity and location considering the load bearing capacity of the structure and provision of efficient access to the tradespersons to minimize distance from point of storage to point of affixing roof coverings to each Support batten assembly. Preferably the gross weight of each group including any container is less than 300 kilograms.


The present invention also provides a tile bearing container or means of keeping a group of Roof Coverings together during transport to a desired location on the roof and also during the process of applying the said roof coverings to the roof structure. The said container is also provided with a means to engage with elements of the roof framework such as rafters by means such as one or more surface or protrusion or cleat; said container may also have one or more restraining means to at least temporarily restrainingly connect said tile bearing container to the roof structure so as to prevent said tile bearing container and its contents from being dislodged from the said roof framing. Said tile bearing container is preferably removed from the roof structure for re-use together with any unused tiles after all the required tiles or slates are removed therefrom. Said tile bearing container reduces the need of manually conveying tiles to the point of use on a roof and improves safety and efficiency and reduces breakage and other consequential costs. In one embodiment of this aspect said one or more protruding cleats and or adjacent surface of said tile bearing container abut at least one rafter 200 and at least one of said Support battens 300 or 310 or Spacer Pieces 600 referred to in FIG. 2 and FIG. 3 and elsewhere herein


The present invention also provides for an improved method and devices to assist tradespersons in safely and precisely installing the many and various elements including the many discrete roof plane surfaces which comprise a finished roof. One preferred device provides a computer based application hereinafter referred to as app, to convey electronically by Wi-Fi or other means, to a mobile telephone or other device carried by a tradesperson/user working on the roof, the details of the roofing job so that the multitude of vital information is always conveniently available without the need to leave the roof to review said information. The information provided may be via a lap top computer located safely on or nearby to the work site and provide; a roof diagram identifying each of the roof plane surfaces; dimensions and details of the roof including all relevant materials; all materials to be installed in conjunction or associated with the roof so that proper allowances may be made to allow for items such as roof penetrations or mountings or flashings which may be done by other trades. Such information may advantageously also include; details of other trades to do work associated with or connected with the roof including intended work schedule and contact details; and the app may usefully serve up a form to the user showing the dimensions of each roof plane surface and estimated batten spacing and all materials required and providing user to check measurements on the roof and input the actual measurements whereupon the app will re-calculate and transmit to the user the recalculated information. Transmitted information especially regarding tile/batten spacing may advantageously also be communicated to and received by another device which may adjusted mechanically to reflect the desired spacing of battens on a particular roof surface and confirm to the user by sound or visual response when the physical adjustment has achieved the received desired dimension at which point the user locks the device or gauge which may them be employed to set the spacing for all batten rows on that roof plane surface.

However, to increase the level of fixings which may be desirable in geographical locations which experience cyclones or other extreme weather events the spacer pieces may be separately fixed (fixings not shown) to rafters 200



FIGS. 6
a. to f. illustrate a illustrate a preferred embodiment of a clip made of metal wire which provides fixed or removable engagement means between a roof structure and Roof Coverings.



FIG. 6a


Shows a side view of a clip 800 shaped to retain roof coverings on a roof structure and having adjacent to end 807, a shape 805 configured to engage and restrain said roof coverings and at a distal end 808 a shape 806 configured to engage fixingly or removably with Support battens such as in FIG. 3300 or lightweight battens 500. Preferably the elements of said clip configured so that; Bend or intersection 802 formed adjacent to the intersection of dotted lines B and C assists the said clip in retention of Roof Coverings. The included angle at intersection 802 is ideally greater than 95 degrees but less than 178 degrees and in one preferred instance is 168 degrees.


Bend or intersection 804 formed adjacent to the intersection of dotted lines D and A assists the said clip in retention of Roof Coverings. The included angle at intersection 804 is ideally greater than 20 degrees but less than 178 degrees and in one preferred instance is 102 degrees.


Angle 803 formed by dotted lines D and A when viewed in the present plane is a reflection of the the offset angle between elements of portion 806. A first element of said portion 806 extends from end 808 to a distal end of said first element at a point adjacent to the intersection of dotted lines ‘D’ and ‘A’ and a second element extending from a point adjacent to the vertex of angle 804 to a distal end point adjacent to a next bend corresponding in the present view with the intersection of dotted lines ‘D’ and ‘A’. A third element connects the first and second elements and said third element is preferably up to 20% of the total length of the said clip.


The disposition of the said elements disclosed herein assists with placement of portion 806 of clip 800 into a fixed or removable engagement with (referring to FIG. 6e) Support batten 300 and retention of Roof Coverings.


The included angle corresponding to angle 803 is ideally between zero degrees and 360 degrees and in the preferred embodiment disclosed is 15 degrees.


Angle 803 determines the at rest position of end 808 and consequently the amount of “spring” force to be overcome when said first and second elements are aligned to enable insertion of portion 806 of clip 800 into (referring to FIG. 6e) pocket 320 of Support batten 300. Conversely, once inserted in pocket 320 the inherent spring force stored causes end 808 to engage with the wall of pocket 320 such that clip 800 is retained in pocket 320 of Support batten 300



FIG. 6b


Illustrates an isometric view of said roof coverings retaining clip 800 shown in FIG. 6a. and having adjacent to end 807, a shape 805 to engage and restrain said roof coverings and at another end 808 a shape 806 formed to engage fixingly or removably with Support battens such as in FIG. 3300 and FIG. 6e or lightweight battens 500



FIG. 6c


Illustrates a parallel projection view from above of clip 800 shown in FIG. 6a and FIG. 6b and having end 807and a distal end 808.



FIG. 6d


Illustrates a parallel projection view of metal clip 800 shown in FIGS. 6a, 6b and 6c end view looking at end 808, and having; a shape 806 formed to engage fixingly or removably with Support battens such as in FIG. 3300 and FIG. 6e pocket 320 or lightweight battens 500



FIG. 6e


Illustrates view from one side of clip 800 together with a section of a Support batten 300 showing the cooperation between the wall of a pocket 320 in said Support batten 300 and the end 808 and adjacent portion 806 of clip 800; end 808 is drawn in the position it would occupy with no spring force restraining it against the wall of pocket 320; dotted line elongated rectangles 1200 and 1201 partially represent a sectional view of the location of roof coverings slates restrained by clip 800. Said slates 1200 retained by co-operation of parts of its surface abutting surfaces of clip 800 especially portion 805 thereof and by co-operation of one end of slate 1201 and adjacent/abutting surface of portion 805 of clip 800 and underlayer 1210; to insert slate 1201 end 807 must be raised against the natural spring force from its at rest position abutting the proximate surface of Support batten 300 and thus when slate 1201 is in the position shown herein there is a force exerted thereby in addition to down force exerted by slate 1200 to hold said slate 1201 and underlayer 1210 against the adjacent surfaces of Support batten 300.


Walls of Pocket 320 are intended to abut closely with the adjacent surfaces of portion 806 of clip 800 but for sake of clarity are drawn herein instead with a gap.



FIG. 6f


Illustrates a perspective view of a piece of a batten assembly 310c including clip 800, support batten 300 having pockets 320 to receive clips 800. Optionally after insertion of clip 800 into pocket 320 additional clip retention means may be employed by mechanical fixing such as a such as adhesive or a nail or screw inserted into pocket 320 or through the walls of pocket 320.



FIG. 7


Illustrates another exemplar of a roof coverings retaining clip 800 whereby the clip is affixed to the batten 300 by means of portion of clip 800 inserted through the material of the batten and secured by mechanical means 810.
