AGENT ited rates This invention relates to sheet metal awnings of improved design as hereinafter particularly pointed out.

Among the objects of the invention are to provide a novel and improved sheet metal awning. It is a par ticular object of the invention to provide an awning which can be easily fabricated and easily erected. A further object of the invention is to provide an awning which is economical in construction and which can be assembled very quickly. It is also an object to minimize the proportion of scrap in the manufacture of sheet metal awnings. Other and further objects of the invention will be apparent as the detailed description of the invention proceeds.

In the drawings Fig. l is a perspective view of one form of the awning attached to an ordinary window.

Fig. 2 is an enlarged view of a section of Fig. 3 at the junction of the inclined portion and the skirt portion of the awning panels.

Fig. 3 is a cross sectional view of the awning.

Fig. 4 is a cross sectional view of the roof and drain panels.

Fig. 5 is an enlarged perspective view showing a portion of one embodiment of the front rail of the frame.

Fig. 6 is a cross sectional view of a drain panel show ing one means of securing it to the front rail.

In the embodiment of the invention shown in the drawings a simple roof form applicable to an ordinary window is shown for purposes of illustration. However, the form and design may vary depending upon the type of building and the part to which the awning is attached. The preferred material of construction is aluminum but steel, magnesium and other sheet metal materials may be used.

The awning includes a simple horizontal frame comprising a front member or rail 2 and side members at right angles thereto. A side member 1 is shown in Fig. 3. The end next to the building is provided with a means for securing it thereto, as for example by means of a clip 3. Above the plane of the frame next to the building is a horizontal rail 4. This serves as a support for the panels of the roof and for securing the awning to the building or like support by means of wood screws 15, bolts or the like.

Supported by the parallel, horizontal rails 2 and 4 are a series of alternate drain and roof panels 7 and 7a. These include vertically disposed extensions which provide a skirt at the front of the awning. The drain panels 7 are provided at the edges thereof with upturned, crimped flanges 9 at right angles to the plane of the surface. The roof panels are provided with downturned, crimped flanges 9a at right angles to the plane of the surface. From the standpoint of manufacture the roof and drain panels actually are identical except in the direction of the bend forming the skirt but differ in their relative positions. This of course provides great economy in manufacture and a saving of metal. The drain panels are secured to the upper rail by metal screws 6 visible atent F 2,788,548 Patented Apr. 16, 1957 in Figs. 1 and 3. Metal screws 6 visible in Figs. 2 and 6 are also employed to secure the drain panels to the lower rail.

As shown in Fig. 4, the roof panels are held in place very simply by the crimped flanges. In erecting the awning the drain panels are first correctly spaced and secured. Then the roof panels 7a are snapped in place. The latter overlap the drain panels, providing a water tight construction. The crimped flanges are in close juxtaposition so that both lateral and vertical movement is prohibited. This arrangement obviates the necessity of using screws or clips for fastening the roof panels.

Whether the awning is prefabricated or assembled on the building, the assembly can be done very quickly and easily.

As illustrated in Fig. 5, studs 12 are provided on the front rail by cutting out and upturning portions of the metal at the spacings required by the widths of the panels. The flanges of the drain panels are secured to these studs by means of metal screws 6 visible in Fig. 6. The screws are then hidden by the flanges of the overlapping roof panels 7a. It is also feasible to secure the drain panels to the front rail by screws through the flat surface of the panels instead of screws through the flanges and studs. In this embodiment of the invention (not shown) the heads of the screws through the drain panels and front rail would be visible from the front of the awning. In such case it is preferred to secure the drain panels to the front rail at the vertical skirt portion instead of at the inclined portion. This provides a durable construction. The skirt is normally within easy reach of passersby so that if unsupported it is liable to be bent or mutilated, spoiling the appearance of the awning.

In the embodiment of the invention illustrated the front rail serves as a brace for the skirt although the hidden screws are in the flanges at the inclined portion of the drain panels. It will be apparent that if desired the studs 12 could be so positioned in the front rail that the hidden screws could be in the skirt portion.

The sides of the awning are provided with a curtain comprising vertically disposed parallel panels 8. These are provided at the edges with flanges 10 turned outward at right angles to the plane of the panel surface. Of course these flanges need not be crimped and preferably are plain as illustrated. The panels of the curtain are spaced apart to allow free air circulation underneath the awning as shown in Fig. 3. The metal screws 6 fasten the bottom of the panels to the side section of the frame 1. At the top they are secured to an inclined bracing member 5. This bracing member is also secured to a flange of the panel at the edge of the inclined roof and drain sections.

In the embodiment illustrated in Fig. l, the edge of the awning terminates in a drain panel 11 which has on one side an upturned crimped flange as herein described interlocked with the overlapping roof panel. At the edge of the awning, however, it has a downturned plain flange 16. Metal screws pass through this flange, the curtain panels and the inclined bracing member. The width of the panels at the edges may vary from the others to permit adjustment to the exact width of awning desired.

Since the flanges of the alternate roof and drain panels are crimped, it is not convenient to overlap them at the bend for the skirt so a wing-shaped section of the metal, not shown, is cut from the panels at the point desired for the bend. Referring to Fig. 2, the bending of the drain panels results in a widening of the notch so that in the assembled awning there appears a wide notch 13 in the drain panel. The bending of the roof panels is of course in the other direction with respect to the notch so that the edges of the metal almost meet, leaving the small gap 14.

It is apparent from the foregoing that a very simple economical sheet metal awningis provided. Equivalentswill berobvious to those skilled in the art. For example instead of metal screws, rivets and other means may be used: to fasten the drain panels to the rails. The dimensionsof the panels and flanges may vary as desired. It has been found that a /3 in. overall width of the roof and. drain panels is convenient and attractive in appearance and canbe conveniently made up from 7 in. strip aluminum. The. distance from the surface of the panel to the beginning; of the crimp is conveniently about in. and, from, this point to the end of the flange about in. Atcrimp about in, depth measuring at the deepest portion from the plane of the surface of the flange to the insidesurface of the metal at thev bottom of the crimp is very satisfactory for secure locking.

It is intended to cover all changes and modifications of the examples of the invention herein chosen for purposes ofdisclosure which do not constitute departures from the spirit and scope of the invention.
