8 Claims. (CI. zo 57.5)

This invention relates to an improved awning and flashing strip therefor.

The awning is of the type having a roof formed with sheet-metal, channel-shaped elements. These elements are assembled with the fiashing strip on a frame structure which is fastened against a building. The channel elements are formecl with parallel fianges along their longitudinal edges. Some of the channels in the roof are positioned with their fianges directed upwardly. These channels are spaced laterally from each other and are known to the trade as "drains" The other channels of the roof assembly are positioned with their anges extending downwardly and each bridges over the space between two adjacent drains. These latter channels are referred to in the trade as "coversj' and these too are spaced laterally from each other. According to this invention means is provided at the bottom of each edge of each cover to hold it to anchor means which-Will be described in what follows.

The flashing strip fits across the upper end of the roof. The fiashing strip includes a vertical portion adapted to be fastened against a building and another portion which angles outwardly from the vertical portion with upwardly extending anchor means on which the covers are sprung to hold them in assembled relation with the drains. The anchor means on the flashing strip project upwardly between the downwardly extending fianges of each cover. Any complementary looking means may be provided on the cover flanges and the anchor means which prevents upward movement of the covers from the anchor means. The preferred anchor means maintains pressure contact with the inside upper surface of each fiange to prevent the covers from rattling against the anchor means. The frictional engagement of the covers with the anchors holds them in place. The top corners of the anchor means are preferably beveled downwardly to facilitate the engagement of the cover with the anchor.

The supporting structure for the awning includes a cross member which is located on a part of the frame away from the building and is preferably parallel with the fiashing strip. This member is provided with anchor means which 'extend upwardly into the covers through the space between the drains. These are generally the same shape as the anchor means employed on the fiashing strip, and function in the same manner. The crossbar anchors hold the drains in proper position. The upper end of each drain may be fastened to the fiashing strip in any suitable manner.

A preferred form of the invention is shown in the drawings. In the drawings- Fig. 1 is a perspective view showing a fragmentary portion of the awning mounted on abuilding 2 with a portion of the supporting structure broken away;

The sloping roof portion I is formed of the sheet-metal drains 2 and covers 3. Each of the covers is provided with parallel side flanges sa (Fig. 3) and along the outer edge of each flange there is an inwardly turned lip Ba. The drains also have similar parallel side fianges 51 which terminate in inwardly turned lips Gb. As shown in Fig. 3 the drains 2 are positioned with their side fianges 5b directed upwardly and the drains are spaced apart from each other. The covers 3 are positioned above the drains so that each bridges the space between two adjacent drains. The outside flange 'I of each outside drain is turned down instead of up. There is no lip on these flanges. The flanges Sa of each cover are directed downwardly toward the drains. Although Fig. 3 shows each fiange 5a of one cover vertically overlapping the adjacent upturned flange 5b on the adjacent drain, this is merely a preferred construction and is not essential. Both. the drains and covers extend the full length of: the sloping roof. The covers are in a plane par-` allel to the plane of the drains and the flanges: of the covers and drains are mutually parallel in the roof assembly. p

The roof is supported at each member 8'(Figs. 1 and 8), the upper end 9 of which is adapted to be fastened to the building The lower, outer end o is connected to the end l I of a horizontal brace member |2 which extends backwardly toward the building and its inner end (not shown) is adapted to be fastened to the building. The member !2 forms an acute angle with the member 8.

The crossbar |4 extends transversely under the roof assembly as shown in Figs. 2, 6 and 8. The ends of crossbar l4 are fastened to the inturned side by a sloping flanges at the bottoms of the sloping members 8 :u The pre ferred fiashing strip 20 (Elg.,5 extends 3 across the upper edge of the roof of the awning, perpendicular to the drains and covers. This flashing strip is preferably shaped by stamping or the like from a single sheet of metal. The fiashing strip includes a vertical portion 2! with holes 22 through it at spaced intervals through which suitable screws 23 (Fig. 1) may be inserted to fasten the fiashing strip against the building. The upper edge of the flashing is bent outwardly away from the vertical portion, and after the awning is mounted on the building the crack between the upper edge 25 and the building is caulked with suitable material to prevent water from seeping between the flashing and the building.

Adjoining the vertical portion 2l of the awning is a flat portion 28 which angles outwardly and downwardly at an obtuse angle with respect to the vertical portion 2 l, at the same angle as the sloping members 8. The upper end of each cover 3 extends over the upper surface of member 28 and the end of each cover may fit directly against the surface of the vertical portion 2! or it may terminate short of the vertical portion as shown in Fig. 6. The fianges 5b are cut away at the upper end of each drainleaving a flat projection which fits under and flat against the undersurface of the member 28 (see Figs. 6 and 7). This projection is fastened to the member 28 by a bolt 33.

.The upper end of each cover 3 is connected to the flashing strip by an anchor which projects upward from the member 28. Preferably these anchor elements are ormed as an integral part of the flashing. from thelower; outer edge of the member 28 and they are spaced the same distance apart as the covers.

Fig. 7 shows the manner in which a cover engages one of the anchors. The preferred anchor is flat and is of the same thickness as the member 28, it being. a continuation of the member 23, The distance between the edges 39 of the anchor is substantially equal to the distance between the fianges sa of the cover so that when the cover is assemhled with the anchor the fianges 5a fit snugly against them. The anchor is continuous from one side to the other to prevent water from draining down the flat portion 28 of the fiashing through the upper, open end of the cover. anchor the inwardly turned lips Sa of the cover fit in the recesses 40 formed near the lower end of. the edges 39 of the anchor. Each lip 60 grips the top edge of its recess tightly.

The covers 3 are Sprung over the anchors 35. To facilitate the engagement of each cover with its anchor both ends of its top edge are beveled clownwardly, as at numeral 42. To engage the cover, it is positioned on the anchor with the lips Sa resting on the beveled edges 42. The cover is then pressed downwardly so that the lips Ba are spread outwardly as they slide over the slanting corners 42. They then move down the edges 39 of the anchor. When the lips reach the recesses 40` they snap into them due to the resilience of the fianges 5a. As shown in Flg. "I, the distance between each recss 40 and the upper edge of the anchor is substantially equal to the height of the fianges 5a sothat the edge 45 fits snugly against and supports the inside surface of the flat center area of the cover.

It is desirable to maintain pressure contact between the top of the anchor means and the inner surface of each cover. This is advantageously ,done by providing a spring, such as the spring They are bent upwardly i When the cover is engaged with the 46 at the top of each anchor. This spring is formed by bending over a thin strip of the sheet metal across the top of the anchor, toward the vertical portion 21 of the ashing strip. This spring strip 46 angles slightly upwardly when it is formed, and it is somewhat springy. When a cover is engaged with the anchor, the spring strip 46 maintains pressure contact with the inside surface of the top of the cover. As shown in the drawings, this pressure contact bends the spring strip to a horizontal position. The resilience of the spring strip maintains upward pressure against the cover, thereby pressing the lips tightly against the roofs of the recesses. Thus, the spring strips hold the covers under tension and prevent them from vibrating and rattling, and from working loose.

Toward their lower or outer ends the drains and covers are Secured to the crossbar |4 by fastening means best shown in Figs. 4, 6 and 8. Preferably this fastening means or anchor is in the form of a clip 41 which is Sprung onto the upper ledge 48 of the crossbar !4. Each clip is located on the bar so that it projects upwardly through the space between two drains 2. The portion of the clip 41 above the crossbar !4 which engages the cover is shaped generally the same as the anchors 35 on the flashing strip. A spring strip 49 is formed along the top of clip 41 for the same purpose as spring strip 46 on the anchor. The edges 50 (Fig. 8) of each clip are cut away near the bottom, at 5I. The upper corners 52 at each side of the clip are beveled. To fasten the covers they are positioned with the lips Sa on the beveled edges 52 and then pressed downwardly so that the fianges are sprung around the edges 59 and slide under the edges 51 in the same manner that the upper ends of the covers are engaged with the anchors 35. The spring strips 49 maintain pressure on the covers and keep the-m from rattling.

A portion of each upwardly extending flange 5b and lip Gb of each drain is cut away adjacent the clips 41 as shown in Fig. 4 to form the slot 54 in each fiange 51). spaced inwardly from each edge 50 of each clip .1 is a slot 55 which extends upwardly from each edge of the portion 58 which clips over the ledge 48 of the crossbar. The slot 55' in the clip fits over the portion of the drain flange 5b remaining below the slot 54. The top of the slot 55 in the clip presses against the bottom of the slot 54 in the drain flange 5b. The Wing portions 51 of each clip extend beyond the slots 54 in flanges 5b and slots 55 in the clip. This assembly holds the drains tightly against the crossbar !4. In asscmbling the awning the clips 41 are fastened to the crossbar 14 after the drains are positioned and the slots 55 are engaged with the portions of the flanges 5b which remain after cuttng the slots 54. The clips 41 thereby festen both the drains and the covers to the crossbar [4. No bolts, rivets or other fasteners are necessary.

In the awning which is illustrated the lips Gb of each drain fit fiat against the inside surface of the cover above it except at clip 41 and at the flashing strip where the lips are cut away. The lips Sa of the covers fit against the inside surfaces of the drains in a similar manner. The improved structure for fastening the drains and covers, to which this invention relates, may be employed regardless of whether the drains and covers fit tightly against each other or are spaced apart as will be apparent to anyone familiar with awnings of this type. It is also evident that as many drains 2 and covers 3 may be used as needed to obtain an awning of the desired width.

Any suitable type of side curtain may be fastened to the supporting frame at each side of the roof, although none is shown in the drawing, and none is necessary.

The outer, lower ends of the drains and covers are bent vertically downward in the preferred awning to form a valance 58 (Fig. 1) across the front of the roof. The improved awning structure of this invention is particularly economical to construct because it may be shipped in a knocked-down condition and assembled at the site where it is to be installed by men not skilled in riveting, etc.
