Abstract
A sheet metal exterior sheathing element particu1arly suitable as a roofing tile. The tile has inter-engageable channels on its opposing longitudinal sides, one channel (6, 7) being on the underside and the channe l (9) on the upperside of the tile. A mounting tab (10) extends from adjacent the upperside channel (9) substantially co-p1anar to the body of the tile. The channels enable two tiles (1a, 1b) to be joined in an over1apping side by side re1ationship with their corresponding channel sections engaged. Each tile (1a, 1b) can be fixed to a supporting structure by their mounting tabs (10). A third tile (1c) can then be joined longitudinally of the first two tiles (1a, 1b) by engaging its underside channel (6) over and about their joined upperside channel sections (9). It can also be fixed to the supporting structure and the steps repeated to sheath a desired area.

IMPROVEMENTS IN AND RELATING TO ROOFING OR SHEATHING.
TECHNICAL FIELD OF THE INVENTION.
This invention relates to an exterior sheathing element and a method of applying exterior sheathing to a structure. More particularly the invention relates to a sheet metal sheathing element useful for roofing.
BACKGROUND ART OF THE INVENTION.
A variety of exterior sheathing elements including those formed from sheet metal are known.
Traditionally with exterior sheathing, particularly roofing, the word "tile"
is used to indicate a single tile such as a concrete tile. With the development of sheet metal sheathing it has become well established to manufacture elements that visually replicate the designs of such traditional tiles. Because these sheet metal tiles are substantially lighter than their concrete counterparts they are normally manufactured as multiple units, that is, as to replicate say three or four traditional tiles. This capability is one of the advantages these tile have over the traditional "single" tile. This invention is primarily concerned with a multiple sheet metal tile and herein the term "tile" is used accordingly. However, the nature of the invention does lend itself for manufacture and use as a single tile element and the term is to be considered as being applicable to either form of tile.
The prior art includes various structures of such tiles (sometimes referred to as shingles) and also metal and vinyl sidings. In situ the sidings or tiles are overlapped both laterally with adjacent sidings/tiles as well as with upper and lower siding/tile courses to achieve a weatherproof structure. As part of the overlap between courses some sidings/tiles include a lower edge underside lip which locates within an upper edge channel of the next lower siding/tile course. However, a fundamental difference between the tiles and sidings is the substantial length of the latter. This necessitates that a siding incorporate means to compensate for longitudinal expansion and contraction particularly at the lateral overlap of adjacent sidings. Their in situ mounting means also need to allow for this. US
Patents 3,520,099; 3,159,943 describe such single course sidings and Canadian Patent 1251317, describes a multi-course panel like siding. This need to allow for movement is recognised in US Patent 5,475,963 which describes a device for re-securing disengaged sidings. Owing to the relatively shorter length of tiles, they may be rigidly fixed to a supporting substrate. It follows that any overlap, both laterally and between courses of and between tiles may also be fixed and there is no need for compensating mounting means such as described in US Patent 5,363,623 or specialised mounting brackets as described in US Patent 4,266,385. US Patents 2,811,118 and 5,657,603 describe metal shingles which are fixed in situ and which are also not merely overlapped with one another but also interlocked to one another. This interlocking may well have benefits but does add to installation time, requiring precise in situ alignment, and in some cases, such as in US Patent 5,657,603 also folding. These requirements also tend to require more skilled installers both aspects adding to the costs of using such a shingle or tile.
A first object of this invention is to provide a sheet metal sheathing element particularly useful as a roofmg tile that can be manufactured utilising thinner sheet metal than typically used with sheet metal tiles. A second object is to provide a sheet metal tile that replicates a traditional wooden shingle "tile" particularly in a multiple configuration thereof as discussed above relative to concrete tiles. A further object of this invention is to provide such a sheathing element adapted for individual fixing to a supporting structure and subsequent conjoining and fixing of further tiles both laterally and longitudinally of the first tile.
The structure of the tile enables adjacent overlapping tiles to be located within one another but without the need of a fixed interlock as described in the above mentioned shingle patents. The steps can be repeated to cover a desired area of a supporting structure and thus a further object is to provide a method of affixing sheathing tile to a structure. Yet a further object is to provide the public with a further choice in sheathing elements in particular a sheathing element suitable for mounting by relatively unskilled people.

BRIEF DESCRIPTION OF DRAWINGS.
Fig. 1 is an upperface or obverse view of two sheathing elements being presented to one another in readiness for being laterally overlapped and engaged with one another as depicted in Figure 2, and 5 Fig. 3 depicts a third sheathing element adjacent the two laterally overlapped elements depicted in Figure 2, the third element being presented to be joined to the first two elements in a position depicted schematically by broken-line 3, and Fig. 4 is a partly schematic side view essentially in the direction of arrow A
on Figure 3 and with the elements engaged with one another and mounted in situ onto a support extending adjacently therebeneath for substantially the complete span of the sheathing and Fig. 5 is a similar view to Figure 4 depicting a variation of the sheathing element mounted to support rafters disposed in a spaced apart manner beneath the sheathing.
BEST MODE OF CARRYING OUT OF THE INVENTION.
A sheathing element 22 is preferably manufactured from sheet metal in known manner such as by pressing, roll forming and/or folding. Preferably element 22 is designed as a multiple tile as discussed above and in particular to replicate a plurality of wooden shingles arranged in a side overlapping side relationship as in situ. While the tile 22 of this invention can be manufactured from sheet metal as typically used for sheet metal sheathing tiles; the design lends itself suitable for manufacture using thinner sheet metal. This in turn enables the tile to economically replicate wooden shingles. Preferably sheet metal in the region of 0.27mm gauge is used, in situ, this necessitating a support extending completely therebeneath. Typically such a support is, as depicted in Figure 4, plywood or similar sheets 2 being mounted on rafters 16 or similar elements to completely cover an area. Because of their light weight, their design and their preferred utilisation with such a support the tile of this invention is suitable for mounting by relatively unskilled people.
Preferably sheathing element 22 is pressed into a thin or substantially single plane configuration having an overall thickness, including inter-engaging channels 7 and 9 as described below, similar to that of a typical wooden shingle. The tile 22 has a main body 1 having a fust lateral side 20 and a second lateral side 21 with corresponding lateral side portions lc, lb. Indentations indicated by various longitudinally extending lines on the drawings are preferably provided to strengthen the main body 1 and provide the desired visual wooden shingle replication. These indentations are not pronounced and in the preferred form the tile 22 has the exterior face thereof coated, in known manner, with stone chips or similar (not shown for the sake of clarity) to enhance this replication.
The indentations include weather ingress inhibiting ribs 5, preferably longitudinally extending in a corrugated manner and preferably being more pronounced than most of the remainder of the indentations. The ribs 5 are disposed along at least lateral side portion lb of the tile 22, being that side that in use is disposed on the underside when overlapped (as depicted by Figs. 1 and 2) with another tile 23. In the drawings both sides of a tile 22 are shown with ribs 4 but they are not necessary on lateral side portion 1c that will be uppermost in situ.
Tile 22 has a first edge portion 6 opposite a second edge portion 8 extending between the first and second lateral sides 20, 21. First edge portion 6 is formed back on itself such as by folding to form a channel 7 on what, in situ, will be an innerface of the tile 22. On second edge portion 8 a further channel 9 is formed on what, in situ, will be an outerface of the tile 22.
(While the tile 22 is preferably wider than it is long the terms "side" and "longitudinal' are used in the manner chosen to assist clarity.) Channel 9 is also preferably formed by folding and a mounting tab 10 is also formed projecting from that outer edge portion 8.
Mounting tab 10 extends along the edge portion 8 but terminates short of the first lateral side 20 of the tile 22 to leave a mounting tab free section 11. The tab free section 11 preferably corresponds to the lateral side portion lc or in other words that side portion of a tile 22 that will be uppermost when in a side overlapping relationship with another tile 23. It will be understood by those skilled in the art and the following description that mounting tab 10 may also terminate short of the other lateral side 21 of the element and need not be continuous.
Mounting tab 10 is preferably formed by providing a return fold on the mounting tab forming part of edge 8, the material forming mounting tab 10 having a return extending back over itself in pressed together relationship about the material forming channel 9 and then outwardly substantially co-planar with the main body 1 of the tile 22. The side of edge portion 8 distal of mounting tab free part 11 and the associated engaging section of edge portion 6 may be stepped, as indicated at 17 on tile 22 in Figure 1, to assist the side overlap engagement, and continuity of line, of one tile with another. For similar reasons, at the area 17, channel 9 may be marginally "opened" and at the tab free part 11 marginally "closed".
The construction and arrangement of the tile 22 enables a plurality of tiles 22, 23 to be laterally overlapped with one another as depicted in Fig. 2. Referring in particular to Fig. 1, the overlap is undertaken by presenting tile 22 to a second tile 23. This is indicated by double headed arrow 13, the overlap providing their corresponding edge portions 6 and 8 are engaged within one another. More particularly, the edge portion 6 of tile 23 locates within channel 7 of tile 22 and the tab flee section 11 of edge portion 8 of tile 221ocates in channel 9 of tile 23.
Referring in particular to Fig. 3 a third tile 24 can then be presented; as indicated by the double headed arrow 15, to tiles 22 and 23. Preferably the presentation is as to engage the folded edge 7 of tile 24 over and about the overlapping sections of folded second edges 8 of the tiles 22 and 23 and the adjacent sections of each of the second edges 8 as to extend to either side of that overlap. This relationship of three such tiles 22, 23 and 24 enhances the weathering capabilities of the junctions between the tiles 22, 23 and 24. For clarity, this engagement is depicted in side view schematically in Figs. 4 and 5, the engagement being in the nature of a close nesting or clipping together.
A preferred method of in situ mounting is to connect tiles 22, 23 and 24 in a repeating sequence of that described above. In so doing the tiles are rested on backing support sheet 2 and fixed thereto such as by stapling 12 through the mounting tabs 10 into the sheet 2. These steps are substantially repeated to cover the whole of a required area. In so doing the mounting tabs 10 are hidden from view and a continuous sheathing finish achieved.
Referring in particular to Fig. 5 a variation of the sheathing element 22 is depicted. This sheathing element 25 is preferably manufactured from thicker sheet metal in the region of 0.5mm gauge sheet metal. Mounting tab 10 incorporates a laterally extending channel 18 that can be used as a batten to affix the sheathing elements ld directly to spaced apart rafters 16.
(i) the first lateral side portion of the first element is laterally overlapped with said second lateral side portion of the second element so that the overlapping section of the second edge portion of the first element locates within the outerface channel of the second element and the overlapping section of the first edge portion of the second element locates within the innerface channel of the first element; and (ii) said first edge portion of the third element is mounted over the overlapping sections of the second edge portions of the first and second elements as well as the adjacent sections of each of their second edge portions, with the first edge portion of the third element locating in the outerface channels of the laterally overlapping first and second elements.
According to a fourth aspect of this invention there is provided a method of exterior sheathing a structure with a plurality of sheathing elements as described in the first or second aspects of this invention comprising substantially of repeating the steps of positioning a first sheathing element on a sheathing element support of the structure, positioning a second sheathing element with a side section thereof in an overlapping relationship with a section side of the first element and in so doing ensuring their corresponding folded edge portions engage one within the other by the side section of the first folded edge portion of the underlay element being located in the channel formed by the corresponding section of the overlay element, and the side section of the second folded section of the overlay element being located in the channel formed by the corresponding section of the underlay element, and positioning a first folded edge portion of a third sheathing element in engagement over the overlapping sections and adjacent sections of the second folded edge portions of the first and second sheathing elements with those second folded edge sections being located in the channel formed by the first folded edge portion of the third element, and throughout utilising mounting means with the mounting tabs to affix the sheathing elements to the support.
BRIEF DESCRIPTION OF DRAWINGS.
Fig. 1 is an upperface or obverse view of two sheathing elements being presented to one another in readiness for being laterally overlapped and engaged with one another as depicted in Figure 2, and 5 Fig. 3 depicts a third sheathing element adjacent the two laterally overlapped elements depicted in Figure 2, the third element being presented to be joined to the first two elements in a position depicted schematically by broken-line 3, and Fig. 4 is a partly schematic side view essentially in the direction of arrow A
on Figure 3 and with the elements engaged with one another and mounted in situ onto a support extending adjacently therebeneath for substantially the complete span of the sheathing and Fig. 5 is a similar view to Figure 4 depicting a variation of the sheathing element mounted to support rafters disposed in a spaced apart manner beneath the sheathing.
BEST MODE OF CARRYING OUT OF THE INVENTION.
A sheathing element 22 is preferably manufactured from sheet metal in known manner such as by pressing, roll forming and/or folding. Preferably element 22 is designed as a multiple tile as discussed above and in particular to replicate a plurality of wooden shingles arranged in a side overlapping side relationship as in situ. While the tile 22 of this invention can be manufactured from sheet metal as typically used for sheet metal sheathing tiles; the design lends itself suitable for manufacture using thinner sheet metal. This in turn enables the tile to economically replicate wooden shingles. Preferably sheet metal in the region of 0.27mm gauge is used, in situ, this necessitating a support extending completely therebeneath. Typically such a support is, as depicted in Figure 4, plywood or similar sheets 2 being mounted on rafters 16 or similar elements to completely cover an area. Because of their light weight, their design and their preferred utilisation with such a support the tile of this invention is suitable for mounting by relatively unskilled people.
Preferably sheathing element 22 is pressed into a thin or substantially single plane configuration having an overall thickness, including inter-engaging channels 7 and 9 as described below, similar to that of a typical wooden shingle. The tile 22 has a main body 1 having a fust lateral side 20 and a second lateral side 21 with corresponding lateral side portions lc, lb. Indentations indicated by various longitudinally extending lines on the drawings are preferably provided to strengthen the main body 1 and provide the desired visual wooden shingle replication. These indentations are not pronounced and in the preferred form the tile 22 has the exterior face thereof coated, in known manner, with stone chips or similar (not shown for the sake of clarity) to enhance this replication.
The indentations include weather ingress inhibiting ribs 5, preferably longitudinally extending in a corrugated manner and preferably being more pronounced than most of the remainder of the indentations. The ribs 5 are disposed along at least lateral side portion lb of the tile 22, being that side that in use is disposed on the underside when overlapped (as depicted by Figs. 1 and 2) with another tile 23. In the drawings both sides of a tile 22 are shown with ribs 4 but they are not necessary on lateral side portion 1c that will be uppermost in situ.
Tile 22 has a first edge portion 6 opposite a second edge portion 8 extending between the first and second lateral sides 20, 21. First edge portion 6 is formed back on itself such as by folding to form a channel 7 on what, in situ, will be an innerface of the tile 22. On second edge portion 8 a further channel 9 is formed on what, in situ, will be an outerface of the tile 22.
(While the tile 22 is preferably wider than it is long the terms "side" and "longitudinal' are used in the manner chosen to assist clarity.) Channel 9 is also preferably formed by folding and a mounting tab 10 is also formed projecting from that outer edge portion 8.
Mounting tab 10 extends along the edge portion 8 but terminates short of the first lateral side 20 of the tile 22 to leave a mounting tab free section 11. The tab free section 11 preferably corresponds to the lateral side portion lc or in other words that side portion of a tile 22 that will be uppermost when in a side overlapping relationship with another tile 23. It will be understood by those skilled in the art and the following description that mounting tab 10 may also terminate short of the other lateral side 21 of the element and need not be continuous.
Mounting tab 10 is preferably formed by providing a return fold on the mounting tab forming part of edge 8, the material forming mounting tab 10 having a return extending back over itself in pressed together relationship about the material forming channel 9 and then outwardly substantially co-planar with the main body 1 of the tile 22. The side of edge portion 8 distal of mounting tab free part 11 and the associated engaging section of edge portion 6 may be stepped, as indicated at 17 on tile 22 in Figure 1, to assist the side overlap engagement, and continuity of line, of one tile with another. For similar reasons, at the area 17, channel 9 may be marginally "opened" and at the tab free part 11 marginally "closed".
The construction and arrangement of the tile 22 enables a plurality of tiles 22, 23 to be laterally overlapped with one another as depicted in Fig. 2. Referring in particular to Fig. 1, the overlap is undertaken by presenting tile 22 to a second tile 23. This is indicated by double headed arrow 13, the overlap providing their corresponding edge portions 6 and 8 are engaged within one another. More particularly, the edge portion 6 of tile 23 locates within channel 7 of tile 22 and the tab flee section 11 of edge portion 8 of tile 221ocates in channel 9 of tile 23.
Referring in particular to Fig. 3 a third tile 24 can then be presented; as indicated by the double headed arrow 15, to tiles 22 and 23. Preferably the presentation is as to engage the folded edge 7 of tile 24 over and about the overlapping sections of folded second edges 8 of the tiles 22 and 23 and the adjacent sections of each of the second edges 8 as to extend to either side of that overlap. This relationship of three such tiles 22, 23 and 24 enhances the weathering capabilities of the junctions between the tiles 22, 23 and 24. For clarity, this engagement is depicted in side view schematically in Figs. 4 and 5, the engagement being in the nature of a close nesting or clipping together.
A preferred method of in situ mounting is to connect tiles 22, 23 and 24 in a repeating sequence of that described above. In so doing the tiles are rested on backing support sheet 2 and fixed thereto such as by stapling 12 through the mounting tabs 10 into the sheet 2. These steps are substantially repeated to cover the whole of a required area. In so doing the mounting tabs 10 are hidden from view and a continuous sheathing finish achieved.
Referring in particular to Fig. 5 a variation of the sheathing element 22 is depicted. This sheathing element 25 is preferably manufactured from thicker sheet metal in the region of 0.5mm gauge sheet metal. Mounting tab 10 incorporates a laterally extending channel 18 that can be used as a batten to affix the sheathing elements ld directly to spaced apart rafters 16.
