5 Claims.

The present invention relates to awnings and is particularly applicable, although not sarily limited, to sheet metal awnings. cipal object of the invention has to do with the provision of an awning composed oi a number of standardized parts including panels. end walls, and interlocking securing elements, which can be quickly and easily assembled in any desired width without any special tools. A further object relates to the provision of a sheet metal awning comprising an assembly of simple parts which are inexpensive to manufacture and which are readily interchangeable and can be assembled in any desired combination of colors. Still another object relates to the provision of a metal awning that is light in weight but strong and durable in service.

These and other objects and advantages of the invention will become apparent to those skilled in the art after a consideration of the following description, in which reference is made to the drawings appended hereto, in which Figure l is a perspective View of an awning embodying the principles of this invention.

Figure 11 is a side View of the panel shown in Figure 10.

the panel lil, as lndicated by reference numeral Il, to form longitudinally extending grooves i3 beneath the panel. The panels are joined together at their adjacent edges by means of securing strips I3, each strip having its longitudinal edges I4 folded inwardly toward each other to form a C-shaped cross section. 1

As indicated in Figure '7, the panels i@ are joined by placing them together with folded edges l5 substantially in contacting relation, whereupon the securing strip is is slidable longitudinally into interlocking relation, with the folded edges M of the securing strip inserted into the two grooves l 2 in adjacent panels. The width of the strip I3 is substantially of the two adjacent edge folds the contacting panel edges l5 lation.

the lower edge of each panel I3 is rolled downwardly as indicated at 22 to form a transversely extending tubular passage 23 below the plane of the panel. When the panels are assembled, the upper passages 2l of the several panels are disposed in transverse alignment to receive a straight rod 24 extending through the aligned passages throughout the entire width of the awning. Similarly, a straight lower rod 25 is in serted through the aligned lower passages 23, but terminates short of the sides of the awning, as indicated by reference numerals 23, 2l.

The awning further includes a pair of opposite sheet metal end sections 33, 3 )inasmuch as these two end sections are similar except that they are right-hand and left-hand sections, only one section need be described in detail. The righthand end section 36 includes a generally triangular, normally vertical side wall 32 and an inclined panel portion 33 integral therewith along the hypotenuse. The panel section 33 is normally disposed in the plane of the panels it and has a longitudinal edge 33 that is folded beneath the panel section 33 to form an interlocking groove similar to the grooves l2 on the panels l! to provide for joining the end section 35 to the adjacent panel ID by a securing strip i3.

The panel portion 3-3 is also provided with a rolled upper edge 35 to form a tubular passage adapted to align with the upper passage 2| to receive the upper rod 211i. The lower edge of the panel portion 33 is also rolled, as indicated at 35. to receive one leg 3l of a rod, which is bent at angles and has another leg 33 extending through the passage formed by the lower rolled edge 39 of the side wall 32. The rear end of the rod leg 38 is bent downwardly to form a hook 50, which is provided for purposes of mounting, as will be made evident later'. The rod 3l, 38 is rolled into the edge of the end section during manufacture and is, therefore, not removable. The leg 31 of the rod projects from the rolled edge 3S and can be inserted into the lower passage 23 of the adjacent panel l0. The lower rod 25 terminates short of the outer end of the passage 23, at 21, as explained previously, to provide room for the end of the rod leg 31.

A row of scallops A extends around the bottom edge of the awning. Each scallop, as best seen in Figure 9, is formed of sneet metal and has a curved lower edge 46 and a pair of converging upper edges 41. rlhree tabs 68 are integrally formed in the upper portion of the scallop for securing the latter to the awning. The tabs are bent downwardly perpendicular to the scallop and are inserted through small slots 49 in the panels and side walls, after which the tabs can be bent over nat against the panel to clinch them in locking relation.

An awning can be quickly and easily assembled by placing the required number of panels on a table, bottom side up. The scallops can then be clipped to the lower panel edge and the upper and lower rods 24, inserted through the aligned tubular passages 2|, 23, respectively. rIhe securing strips I3 are next slipped over the pairs of adjacent panel edges at the upper edge of the awning and pushed into place. It will be noted in this connection that it is important to have the upper rolled edge 2B on the side of the panels opposite the folded longitudinal edges to permit the securing strips to slide into place. The lower rolled edges 22 must be below the plane of the panels in installed position in order that the scallops will lie smoothly over the lower edge of the awning.

Each of the two end wall sections is then brought into position and the end of the rod leg 31 is inserted into the tubular passage 23 while the upper rod 24 is inserted into the upper rolled edge 35. The last two securing strips |3 are then slipped into place to hold the end wall sections and panels together. The awning is now ready for hanging.

Each panel is notched inwardly at both upper corners, as indicated at 5|) to provide a slot under the rod 24 to receive a supporting hook 5|. Any desired number of hooks 5| can be used, depending on the number of panels in the awning. Pref erably, two hooks 5| are Vsecured to the window f' casing, one at each side, although a third hook at the center of a wide awning is recommended. The hooks 5| are provided with shanks 52 turned down against the window and secured by suitable screws 53.

A pair of lower brackets 54, apertured to receive the hooked ends 40 of rods '38, are secured to the casing by screws 55.

For wide awnings, diagonal brace rods 56 are provided as indicated in Figure 8. Each brace rod is attached between the lower vedge of a side wall 32 and the front edge of the awning. Attachment is made by suitable clamping members 57, 58, secured by bolts 59 to grip the rolled edges 39, 22, respectively.

The awning can be removed simply by lifting it from the hooks 5! and brackets 5A and can be stored either assembled or disassembled. However, `since the awning is of metal it will withstand the winter weather and may be left in place the entire year, if so desired.

The panels maybe made inseveral widths to provide for assembling awnings of vvarious widths. For example, the panels may be made in widths of 3, 6 and 9 inches, from which awnings of any width in multiples of 3 inches may be assembled. The scallops should then be made 3 inches in width. The panels and scallops may also be enameled in several colors, thus permitting the assembly of awnings either of one color or of several diiferent colors of panels. No special tools are needed for assembling or installing the awning, nor are there a large number of small parts such as bolts, nuts, etc., to become lost.

In the modined form of the invention illustrated in Figures 10 and 1l, the longitudinal edges 66 of each panel 65 are folded inwardly toward each other on top of the panel to position the edges BB and hence the securing strips |3 on the top side of the awning above the plane of the panels. In this embodiment, the securing strips are slid into securing position from the top of the awning, as in the rst-described embodiment. This necessitates that the top edge of each panel be rolled downwardly, as indicated at 61, to provide a transversely extending tubular passage 6B below the plane of the panel 35. The lower edge 69 of the panel is also rolled downwardly to form a tubular passage l@ below the plane of the panel. Thus, the scallops 35 bend smoothly over the rolled edge 59, as in 1Figure 4.

An advantage of this embodiment is that the securing strips i3 lie over the crack between the joined edges and prevent water from entering the crack. A hole "El is provided in the panel near the upper end thereof to receive the supporting hook 5 I, in which case it is not necessary to notch the corners of the panel.

Although two embodiments of the invention have been described above, it is not intended to limit the invention to the particular details shown and described, except as set forth in the claims which follow.

I claim:
