A cut-out opens to a boundary edge of the former edge strip. The bent former edge strip on both sides of the cut-out comprises different inclination angles with regard to the back. An independent claim is also included for a dressing.

Description

The invention relates to a metal shingle having a view or front side, a back side, a first side edge, a second side edge parallel to the first side edge, a first fold on the first side edge, on which a first edge strip is bent back over the back, and a second edge Fold on the second side edge, where a second edge strip is bent over the front or front view. The invention further relates to an association of metal shingles according to the invention. More particularly, the invention relates to metal shingles and an association of a plurality of metal shingles intended for mounting on facades or other wall surfaces.

Metal shingles of the type mentioned for tin roofs are for example from DE 195 10 094 A1 , of the US A 140 928 and the US Pat. No. 2,680,415 known.

When laying metal shingles of the type mentioned on a facade or other wall surface, the metal shingles are aligned so that their back faces the wall surface, the first side edge facing downward with the first edge strip bent back over the back, while the second Side edge facing up with the front or front over the visible or front bent second edge strips upwards. In this orientation, the metal shingles are mounted in superimposed rows of a substructure, which may for example consist of a horizontal lathing, a vertical battens or a solid form of wood. For the attachment of metal shingles to such a substructure are in usually pins or screws used, which are punched or screwed through openings in the metal shingles or through openings in so-called booklets, that is on the side edges of the metal shingle protruding Blechnasen, into the substructure.

In order to improve the integrity of the shingles in the dressing and to prevent rainwater from penetrating under the metal shingles, the horizontal rows of metal shingles are overlapped and engaged with adjacent rows by interlocking the edge strips at the adjacent upper and lower side edges, respectively In each case, the edge strips come to lie on the upper side edges of the metal shingles in the lower row when viewed from the front behind the edge strips at the lower side edges of the metal shingles in the next higher row and wherein each of the two edge strips in a formed between the edge strip and a broad side of the other metal shingle formed gusset.

A particularly good cohesion of metal shingles and a particularly safe and rain-resistant dressing are achieved when the metal shingles of each row are also provided at their adjacent side edges, which are also referred to as the third and fourth side edge, also with a fold and a bent edge strip. In this case, if the edge strip is bent over at one of the two side edges to the rear over the back of the metal shingles, while the edge strip on the opposite side edge is bent forward over the viewing or front side, and the edge strips of these side edges can be hooked together during installation or be engaged so that in each case the edge strip on the side edge of a metal shingles protrudes into the gusset between the edge strip and the adjacent broad side of the other metal shingles. The third and fourth side edges are usually aligned at a right angle to the first and second side edges.

Such metal shingles with bent edge strips or with folds on all four side edges can so far but only lay in a bandage, in which the vertical side edges of the metal shingles in a row opposite the vertical side edges of the metal shingles in the two adjacent, arranged above and below rows a small amount are offset, as in the DE 195 10 094 A1 is specified.

Proceeding from this, the present invention seeks to improve a metal shingle and a dressing of a plurality of metal shingles of the type mentioned in that the metal shingles can be laid with any offset in adjacent rows.

This object is achieved in the metal shingle according to the invention that the bent back over the back of the metal shingled first edge strip on the first side edge is provided with a cutout that opens to a boundary edge of the bent first edge strip, and that the bent first edge strip on both sides the section has different angles of inclination with respect to the back.

In an assembly of a plurality of metal shingles laid one above the other in rows, the metal shingles being hooked in overlapping rows and overlapping each other and wherein the adjacent metal shingles in each row are also hooked together and overlapping, Thus, the edge strips on the upper side edges of the metal shingles in the lower row in the region of the lateral overlap of metal shingles in the overlying row when viewed from the view or front side behind the first edge strips on the lower side edges of these metal shingles are passed so that a variable positioning of the metal shingles in both rows is possible.

The solution according to the invention has the further advantage that the bent first edge strip can extend over the entire length of the first lower side edge, so that the downwardly facing side edges of the metal shingles when viewed from below over its entire length a uniform, by have the curvature of the folds embossed appearance.

A uniform uniform appearance of the lower side edges when viewed from below is also achieved in that the first and the third edge strips have edge edges at their adjacent ends, which are inclined with respect to the first and third side edges, since in this way the bent first edge strip adjacent to the first side edge may extend all the way to the corner between the first and the third side edge of the metal shingle, which is advantageously rounded there.

A uniform appearance when viewed from below is also achieved by the fact that the cutout in the first edge strip advantageously does not extend all the way to the first side edge or to the fold on this side edge, so that the section is not visible from below when viewing the dressing is.

In this case, in addition, the lower boundary edge of the cutout adjacent to the first side edge or its fold can also serve as a fulcrum for an adjacent metal shingle in the next higher row, so that the metal shingles of each row have both a horizontal lower side edge and a hanging tip can be moved. A hanging tip lay means that the opposite upper and lower side edges of the metal shingles do not line up in a row, but that these side edges are inclined at a relatively low inclination angle of a few degrees, despite the horizontal orientation of the row, so that the visible corner on the bottom edge of each shingle is a few millimeters lower than the adjacent lower side edge of the adjacent shingle. By hanging with a hanging tip, the dripping of rainwater from the lower side edges can be facilitated.

In order to facilitate the laying of the metal shingles with a hanging tip, the metal shingles advantageously at a corner between the first side edge and the fourth side edge of a corner cutout having a boundary edge parallel to the first side edge and from this same distance as the adjacent to the first side edge boundary edge of the clipping has. Thereby, it can be ensured that the upper and lower side edges of the metal shingles of each row are aligned with each other when the boundary edge of the corner section parallel to the first side edge when laying the shingles at the level of the downward limiting edge of the folded over the front or front side second edge strip the adjacent metal shingles is positioned in the next lower row. If, on the other hand, the metal shingles are raised at the corner cornered corner when laid, until the downwardly facing boundary edge of the front edge is above the viewing angle Front bent bent second edge strip of the adjacent metal shingles in the next lower row against the inside of the first fold or the first side edge, this has the consequence that the metal shingles are laid with a hanging tip and that an identical inclination angle of the lower side edges of the metal shingles without a Measuring is guaranteed. In other words, the corner cutout forms an alignment aid which allows for the optional alignment of the shingles with hanging tip or with aligned horizontal upper and lower side edges.

For this purpose, the cutout in the first edge strip is advantageously provided on the side adjacent to the first side edge with a generally parallel boundary edge, so that a small displacement of the pivot point within the cut when laying with a hanging tip not to a change in the inclination angle of the lower and upper side edges leads, and that when laying horizontally with aligned side edges no deviations from the escape can occur.

A further preferred embodiment of the invention provides that the angle of inclination of a part of the first edge strip between the cutout and the third side edge and the third edge strip is smaller than the inclination angle of the edge strip on the other side of the cutout, in each case with respect to a plane spanned from the back of the metal shingle. Thus, in the dressing, a shorter portion of the first edge strip adjacent to one side of the cut may overlap the front edge of the second edge strip of the adjacent metal shingle in the underlying row, while a longer portion of the first edge strip adjacent to the other side of the cutout may overlap the first edge strip The back of the second edge strip of the adjacent metal shingle in the underlying row overlaps.

Due to the smaller angle of inclination of the edge strip on the side adjacent to the third side edge, the first fold or the first edge strip of a metal shingle can extend into the region of the overlap of the third side edge with the fourth side edge of an adjacent metal shingle in the same row, without the material thickness of the two shingles in the overlapping area becomes excessively large.

The shorter part of the first edge strip is expediently oriented generally parallel to the viewing or front side and the back of the metal shingle, or is slightly inclined from the first side edge in the direction of its boundary edge to the back of the metal shingle, so that he does not like the longer part or Remainder of the first edge strip diverges away from the side edge in the direction of its boundary edge away from the back of the metal shingle.

In the dressing of the shorter part of the first edge strip is advantageously pressed below the overlap region of the two lateral folds against the view or front of the adjacent metal shingles in the same row. Since the shorter part of the first marginal strip, like the rest of the first marginal strip, is connected to the metal shingle only along the first fold, it can deform somewhat elastically due to the contact force against the visible or front side of the adjacent metal shingle. The restoring force caused thereby causes the contact pressure to be maintained even if the metal shingle deforms somewhat as a result of wind forces, thereby providing effective rattle protection in the overlapping area.

Advantageously, the cutout in the first edge strip from the third side edge at a distance which is slightly larger than the width of the fourth edge strip. Such a distance ensures that the cutout is not in the overlap region of the two laterally adjacent metal shingles of a row of the dressing and is fully accessible from the back over its entire width, whereby the passing of the second edge strip on the upper second side edge of an adjacent metal shingles in the next lower row is relieved.

The metal shingles 10 shown in the drawing consist of a thin but stiff light metal sheet and have two flat broadsides, namely a visual or front side 12, which after mounting the metal shingles 10 on a wall surface 14 (FIG. FIGS. 15 and 16 ) which faces away from the wall surface 14 visible side of the metal shingles 10, and an opposite to the viewing or front side 12 rear side 16, which faces after assembly of the wall surface 14.

In order to prevent oxidation of the light metal sheet, the viewing or front side 12 may be provided with a weather-resistant coating, while the back 16 is suitably painted. In principle, however, the viewing or front side 12 could also be anodized.

Unless they need to be cut to fit windows, doors or other wall openings, the metal shingles 10 have a generally rectangular outline, starting from a straight first longitudinal side edge 18, a second longitudinal side edge 20 parallel to the first longitudinal side edge 18, one to the two longitudinal side edges 18 , 20 vertical third narrow side edge 22 and a narrow side edge 22 parallel fourth narrow side edge 24 are limited, as best in Fig. 1 and 2 shown. The longitudinal side edges 18, 20 have in the illustrated metal shingles 10 has a length of about 640 mm, while the narrow side edges 22, 24 have a length of about 365 mm. Other aspect ratios and lengths are of course also possible.

When laying the metal shingles 10 on the wall surface 14 all metal shingles 10 are aligned the same, in such a way that the first longitudinal side edge 18 down, the second longitudinal side edge 20 upwards and viewing the viewing or front side 12 (FIG. Fig. 1 ) the third narrow side edge 22 to the left and the fourth narrow side edge 24 points to the right.

How best in the FIGS. 1 to 5 shown, the metal shingles 10 are provided on all four side edges with a fold on which an edge strip of the light metal sheet is bent to one of the two broad sides 12, 16 of the metal shingle 10 out.

At the first lower longitudinal side edge 18 arranged first fold 26, a first edge strip 28 is bent back over the back 16 of the metal shingle 10. The first edge strip 28 extends almost the entire length of the first longitudinal side edge 18 and is limited along the major part of its length by an upwardly facing in the mounting position boundary edge 30, which is parallel to the longitudinal side edge 18 at a distance of about 20 mm. At its two opposite ends of the edge strip 28 is bounded by two oblique end edges 32, 34 which are aligned at an angle of about 45 degrees to the longitudinal side edge 18 and the boundary edge 30 and from the ends of the boundary edge 30 in the direction of a rounded corner 36 between the first and the third side edge 18 and 22 and in the direction of a corner 38 between the first and the fourth side edge 18 and 24, respectively.

The edge strip 28 is provided in the vicinity of the third side edge 22 with a cutout 40 which opens towards the boundary edge 30. The cutout 40 is limited to the longitudinal side edge 18 by a straight boundary edge 42 which is aligned parallel to the longitudinal side edge 18 and has a distance of about 5 mm from this. On the sides will the cutout 40 is delimited by two boundary edges 44, 46 parallel to the narrow side edges 22, 24. The width of the cutout 40 is about 12 mm, while its center distance from the third narrow side edge 22 is about 40 mm.

How best in Fig. 2 . 3 and 6 shown, a shorter portion 48 of the first edge strip 28 at the first fold 26 is bent so that it is aligned approximately parallel to the back 16 of the metal shingle 10. This shorter portion 48 extends from the boundary edge 44 of the cutout 40 to the adjacent beveled end edge 32. As best shown in FIG Fig. 2 . 4 and 7 a longer portion 50 or remainder of the first edge strip 28 between the opposite boundary edge 46 of the cutout 40 and the oblique end edge 34 adjacent to the fourth narrow side edge 24 is bent at the first fold 26 so that it is from the first longitudinal side edge 18 and the first fold 26th away in the direction of its boundary edge 30 at an angle α of about 15 degrees with respect to the back 16 of the metal shingle 10 is inclined. That is, this part 50 of the first edge strip 28 in the mounting position of the metal shingle 10 upwardly diverging away from the rear side 16.

At the second fold 52 arranged on the second upper longitudinal side edge 20, a second edge strip 54 is bent forwards over the visible or front side 12 of the metal shingle 10 which, with a width of approximately 26 mm, is somewhat wider than the edge strip 28 on the first longitudinal side edge 18 and in the mounting position has a downwardly facing, parallel to the longitudinal side edge 20 boundary edge 60. At the side of the third narrow side edge 22, the second edge strip 54 terminates at a rectangular corner cutout 56, the dimensions of which are approximately 15 × 15 mm. The edge strip 54 is there from a to the two narrow side edges 22, 24 parallel end edge 58th limited. At the side of the fourth narrow side edge 24 of the second edge strip 54 terminates at a distance of about 40 mm from the narrow side edge 24 with a narrow side edge 24 parallel end edge 62. In the middle of the longitudinal side edge 20 of the second edge strip 54 with an elongated passage opening 64 with rounded ends provided, through which a smaller through hole 66 of the metal shingle 10 is accessible.

How best in 3 and 4 shown, the edge strip 54 is inclined from the second longitudinal side edge 20 in the direction of its boundary edge 60 also at an angle of about 15 degrees with respect to the back 16 of the metal shingle 10. In the mounting position of the metal shingle 10, the second edge strip 54 thus diverges downwards away from the rear side 16.

At the third narrow side edge 22 arranged third fold 68, a third edge strip 70 is bent back over the back 16. The edge strip 70 extends from the corner cutout 56 to the first lower longitudinal side edge 18, where it ends with an oblique end edge 72 which extends at a distance of about 5 mm parallel to the adjacent end edge 32 of the first edge strip 28. Apart from the tapered end portion bounded by the end edge 72, the edge strip 70 has a constant width of about 15 mm over its entire length.

How best in Fig. 5 shown, the edge strip 70 is inclined at the third narrow side edge 22 from the fold 68 in the direction of its inner boundary edge 74 at an angle of about 7 to 8 degrees with respect to the back 16 of the metal shingle 10 from the third narrow side edge 22 away.

With these dimensions and this configuration it is achieved that the part 48 of the bent first edge strip 28 on the first longitudinal side edge between the cutout 40 and the end edge 32 no longer than the bent edge strip 70 on the third narrow side edge 22 projects beyond the rear side 16 of the metal shingle 10 ,

At the fourth fold edge 76 arranged on the fourth narrow edge 24, a fourth edge strip 78 is bent forward over the viewing or front side 12. The edge strip 78 terminates at a distance of about 50 mm from the first longitudinal side edge 18 and at a distance of about 60 mm from the second longitudinal side edge 20 with a longitudinal side edges 18, 20 parallel lower and upper end edge 80 and 82. The fourth edge strip 78th has over its entire length a constant width of about 30 mm and is provided at a distance of about 80 mm from the second longitudinal side edge 20 with an elongated passage opening 84 with rounded ends, through which a smaller through-hole 86 of the metal shingle 10 is accessible.

The bent edge strip 78 on the fourth narrow side edge 24 is inclined from the fold 76 in the direction of its inner boundary edge 88 at an angle of about 7 to 8 degrees with respect to the viewing or front side 12 of the metal shingle, the angle of the fourth narrow side edge 24 opens how best in Fig. 5 shown.

The metal shingles 10 are also provided at the corner 38 between the first and fourth side edges 18 and 24, respectively, with another rectangular corner cutout 90, as best shown in FIG Fig. 1 and 2 shown. The dimensions of the corner cutout 90 are approximately 7 × 3 mm, wherein the distance between an upper boundary edge 92 of the corner cutout 90, which is parallel to the longitudinal side edges 18, 20, and the first longitudinal side edge 18 is exactly the distance between the lower boundary edge 42 of the cutout 40 and the first longitudinal side edge 18 corresponds. The corner cut 90 serves as an assembly aid, as will be explained below.

All folds 26, 52, 68 and 76 have along the respective side edge 18, 20, 22 and 24 a radius of curvature of about 2 to 3 mm. In the area of the viewing or front side 12 not covered by the second fold 52, beyond the adjacent upper end edge 62 of the fourth edge strip 54, the metal shingle 10 is provided with a further through-bore 94 whose diameter, like the diameter of the through-holes 66 and 86, is approximately 5 mm ,

For laying the metal shingles 10 on the wall surface 12, the wall surface 12 is first provided with a substructure, which in Fig. 15 from a horizontal battens and in Fig. 11 consists of a vertical batten, ie slats 98, which are fixed in parallel alignment in the vertical or horizontal distance from each other on the wall. However, the substructure may alternatively consist of a solid form of wood.

The laying of the metal shingles 10 is carried out from bottom to top in horizontal rows, as in FIGS. 15 and 16 illustrated, wherein the metal shingles 10 in each adjacent rows have a horizontal offset. In other words, the vertical side edges 22, 24 of the shingles 10 of each row opposite the vertical side edges 22, 24 of the shingles 10 in the underlying row are to a certain extent to the left and opposite the vertical side edges 22, 24 of the shingles 10 in the above lying row to the right by the same amount. If the substructure consists of a horizontal battens ( Fig. 15 ) or from a solid formwork Wood, this offset can be chosen completely arbitrary in the metal shingles 10 according to the invention. In a substructure of a vertical lathing, however, the offset depends on the distance of adjacent laths 98, since at least two pins or screws (not shown) are required for attachment of each metal shingle 10 through the through holes 66 and 94 at the upper longitudinal side edge 20 into the Substructure must be beaten or screwed. This means that these through holes 66, 94 must lie over the slats 98 of the substructure, so that the offset of half the length of the longitudinal side edges 18, 20 of the metal shingles 10 corresponds, if the distance of all laths 98 of the vertical lathing is the same and half the length the longitudinal side edges 18, 20 corresponds, as in Fig. 16 shown.

The laying of the metal shingles 10 from bottom to top is expediently carried out in stages, the rows are supplemented from bottom to top by a respective metal shingles 10, which in a laying from right to left, as in Fig. 10 and 11 shown opposite the adjacent metal shingles 10 in the underlying or next lower row by the selected offset is reset to the right. When laid from left to right, the metal shingles 10 would be set back relative to the adjacent metal shingles 10 in the underlying row by the selected offset to the left.

When laying a further metal shingle 10 within a row, the metal shingles 10 is brought to the adjacent, already previously attached to the substructure metal shingle 10 in the region of the facing narrow side edges 22, 24 and the two edge strips 70 and 78 engaged or engaged hooked. Stands out each of the edge strip 78 on the fourth narrow side edge 24 of a in 8 and 9 Metal shingle 10 shown on the right in a gusset 100 between the back 16 and the edge strip 70 on the third narrow side edge 24 of the 8 and 9 On the left adjacent metal shingles 10, wherein it rests against the inside of the fold 68, while the reverse edge strip 70 on the third narrow side edge 22 of the metal shingle 10 shown on the left in a gusset 102 between the viewing or front side 12 and the edge strip 70 on the third narrow side edge of the right shown metal shingles 10 projects, but because of its smaller width does not bear against the inside of the fold 76, as in Fig. 9 shown in section.

When laying another metal shingle 10 in an upper row above two already attached metal shingles 10 in a lower row, the further metal shingles 10 is first positioned so that the rear edge 16 towards bent first edge strip 28 on the viewing or front side 12 of the two adjacent metal shingles 10 comes to rest in the lower row. Subsequently, the metal shingle 10 is moved along the viewing or front side 12 of the two metal shingles 10 already fastened upwards, as indicated by the arrow P in the FIGS. 10 to 14 shown. In this case, the longer part 50 of the bent first edge strip 28 between the cutout 40 and the end edge 34 slides over its entire length under the bent forward second edge strip 54 of the two metal shingles of the lower row, as best in FIGS. 11 and 14 shown. This also applies to the region of the adjacent vertical narrow side edges 22, 24 of the two metal shingles 10 already fastened (in FIG Fig. 10 not shown) in which these metal shingles 10 and their edge strips 70, 78 overlap or are hooked together.

During the displacement of the other metal shingles 10 upwardly bent edge strip 70 slides on the third narrow side edge 22 of the other metal shingles 10 on the front of the bent-over second second edge strip 54 of one of the two already attached metal shingles 10. Since the shorter part 48 of the bent first edge strip 28 between the cutout 40 and the third edge strip 70 no longer than the third edge strip 70 projects beyond the back 16 of the other metal shingles 10, pushes on the approach of the first lower longitudinal side edge 18 of the other metal shingles 10 to the second longitudinal side edges 20 already fastened metal shingles 10 and the shorter portion 48 of the bent first edge strip 28 on the front side of the second edge strip 54 of the two already attached metal shingles 10, as in Fig. 13 shown, and not as the remainder 50 of the bent first edge strip 28 under the second upper edge strip 54 and behind the back.

This has the consequence that the edge strip 54 at the upper longitudinal side edge 20 of the already attached metal shingles 10 when moving up the other metal shingle 10 automatically penetrates into the cutout 40 of the first edge strip 28 of this metal shingle 10 until its boundary edge 60 against the lower boundary edge 42 of the cutout 40th strikes. In this position, the edge strip 54 or a part of the edge strip 54 adjoining the boundary edge 60 extends through the cutout 40 in the edge strip 28, as in FIG Fig. 12 shown, with its lower boundary edge 60 is supported within the cutout 40 on the lower boundary edge 42. The shorter part 48 of the first edge strip 28 thereby overlaps the front side of the second edge strip 54 of one of the two adjacent ones Metal shingles 10 in the lower row, while the rest of the first edge strip 28 overlaps the back of the second edge strip 54 of both adjacent metal shingles 10 in the lower row.

Subsequently, the other metal shingles 10 is moved in the upper row parallel to the already attached metal shingles 10 in the lower row to bring their fourth narrow side edge 24 with the third narrow side edge 22 of the adjacent metal shingles 10 to overlap and the two edge strips 78, 70 to this Narrow side edges 22 to hook each other.

For this purpose, the upper second longitudinal side edge 20 of the adjacent metal shingle 10 is slightly moved away from the wall surface 14 so that the further metal shingle 10 with its fourth narrow side edge 24 can slide under the adjacent metal shingle 10 until its fourth fold 76 under the third fold 68th the adjacent metal shingles 10 has moved therethrough. After the upper second longitudinal side edge 20 of the adjacent metal shingles 10 has been moved back to the wall surface 14, then the other metal shingles 10 is again slightly withdrawn to hook the two edge strips 78, 70 together or in such a way, as in Fig. 9 shown.

In this situation, there is an overlap area in which two adjacent metal shingles 10 in the upper row and an adjacent metal shingle 10 in the lower row overlap at one location, as best shown in FIG Fig. 10 and 13 shown. Viewed from the viewing or front side 12 of the dressing, the corner 36 of FIG Fig. 10 at the top left metal shingles 10, including the lower end of the edge strip 70 and the shorter part 48 of the marginal strip 28. Behind it follows the corner 38 of in Fig. 10 Metal shingles 10 shown at the top right, but without the adjacent end of the edge strip 28. Next follows the upper edge strip 54 of FIG Fig. 10 Shown below metal shingle 10, which is located in front of the end edge 34 of the edge strip 28 on the back of the lower end of the side edge 24 of the Fig. 10 Shown above right metal shingles 10 and behind the lower end of the side edge 24 partially concealed shorter portion 48 of the edge strip 28 to the cutout 40 and extends therethrough behind the longer part 50 of the edge strip 28. At the beginning, the part of the lower metal shingle 10 adjacent to the upper longitudinal side edge 20 follows.

The metal shingles 10 of each row can either be laid so that the lower and upper longitudinal side edges 20 of all metal shingles 10 in the same row are aligned with each other, as in Fig. 15 shown. Alternatively, the metal shingles 10 can also be laid with a hanging tip, as in Fig. 16 shown. In this type of installation, the corner 36 of each metal shingle 10 is a few millimeters lower than its corner 38, so that water from the lower longitudinal side edge 18 can drain better.

Depending on what type of installation is chosen, the metal shingles 10 are slightly tilted before their final attachment to the substructure in one or the other direction, the support point of the lower boundary edge 60 in the cutout 40 serves as a fulcrum.

When laying the metal shingles 10 from left to right, the corner cut 90 at the corner 38 of the metal shingles 10 can serve as an assembly aid by its upper boundary edge 92 with the lower boundary edge 60 of second edge strip 54 of an adjacent metal shingle 10 is brought in the next lower row for alignment when the longitudinal side edges 18, 20 of all metal shingles 10 of each row to be aligned in parallel. If the metal shingles 10, however, to be laid with a hanging tip, the other metal shingles 10 is raised at the corner 38 until the lower boundary edge 60 of the second edge strip 54 of the adjacent metal shingle 10 in the next lower row against the inside of the first fold 26th at the lower first longitudinal side edge 18 of the other metal shingles 10 abuts.

Since the two already attached metal shingles 10 overlap in the next lower row in the region of the interlocked edge strips 70, 78, the dressing after its completion on the viewing or front side 12 along the third narrow side edge 22 of the metal shingles 10 has a small step. Since the lower longitudinal side edge 18 of the metal shingles 10 in the overlying row extends beyond this step, the metal shingle 10 is bent slightly therefrom away from the wall surface 14 to the front. This, in turn, causes the shorter portion 48 of the first edge strip 28 of the metal shingle to be lightly pressed against the front of the second edge strip 54 of one of the two adjacent metal shingles 10 in the next lower row, effectively preventing rattling due to wind forces.
