Referring to the drawing, a wall 1l) is illustrated which may be considered to be an exterior wall of a building and which is shown as provided with a window opening 12 therein. The present invention provides an awning that may be installed adjacent the window opening 12 so as to shield the window opening, although it will be understood that the other uses.

According to the present invention,

Will be described hereinafter in greater detail.

The louvers 28 are preferably made of aluminum,

magnesium, or other suitable material that is suiliciently strong in thin sections to withstand the forces exerted thereon in use, and extend transversely of the supports 14 and 16, the ends of the louvers terminating in outwardly spaced relationship with respect to the outermost flanges of the supports, preferred embodiment ill the cross sectional conto edge portion 32 of each as illustrated in Fig. l. In the ustrated, the louvers 28 are of ur shown in Fig. 2, the upper of the louvers being shaped generally in the cross sectional form of an S having a relatively long upper llange 30, an upper curved portion 34 and a lower curved portion 38. This latter portion 38 is continuous with the of the louvers 28. This main central portion 36 of each lower curved portion 38 of the each louver also forms an abutment engaging the supports 14 and 16 as hereinafter described. The central downwardly,

portion extends outwardly and as Viewed in Figs. 1 and 2, from the upper edge portion and the opposite or lower edge portion of sition, thereby defining a louvers 28.

Such a construction permits the in the assembled po- 46 between adjacent free circun opening shields the direct rays of the sun and substantially prevents the passage of rain through the openings 46 be The flanges 30 of the louvers 28 are fitted into the slots 26 in the supports 14 an in position and louvers and the flanges 3? that are dispo and 22 of each of of each support. prevent relative movement between the the supports are crimped or otherwise to be rigidly secured to the supports without the use of screws, rivets or similar fastening devices and facilitates securing the louvers to the supports with a minimum of tools, time and labor. Such a construction also prevents rattling of the louvers when the louvers are in the installed position. It will be appreciated that this crimping may be readily effected with conventional pliers or any other suitable tool.

For the purpose of bracing the supports 14 and 16, a pair of horizontally disposed channel-shaped struts 48 and 5@ are provided, the struts 48 and Si? preferably being made of the same material as the supports 14 and 16. Each of the struts d8 and 5i) includes a web 52 having integral flanges 54 and 56 depending from opposite sides thereof, the flanges 5dand S6 being spaced apart substantially the same distance as the distance between the flanges and 22 of the supports. As is best illustrated in Figs. l and Z, the supports 14 and 16 are inclined to the plane of the wall 10 while the struts 48 and 50 are substantially perpendicular to the wall when the awning is installed. The outer end of each strut is fitted intermediate the flanges at the lower end of the mating support so as to dene an acute angle. When the outer ends of the struts are fitted in the lower ends of the supports, the flanges 54 and 56 are deflected in a transverse direction, as shown in Fig. 6, so that the flanges 54 and 56 resiliently bear against the adjacent flanges of the supports, thereby providing a locking action. As is seen at 57 in Fig. 2, the outer end portion of each of the struts 48 and 50 is tapered so that the upper edges of the flanges S4 and 56 extend substantially parallel to the web 18 of the mating support. The corner portions S8 and 66 of the flanges 26 and Z2 are reversely folded inwardly about the adjacent portions of the flanges 54 and 56 of the struts 48 and Si) to secure the outer end portions of the supports 14 and 16 to the struts 48 and 58, respectively. To further secure the supports to the struts, a slot 62 is provided in each of the flanges 54 and 56 of the struts 48 and 50, the slots 62 being aligned with the adjacent slot 26 in the mating support. The flange 38 of the lowermost louver 28 extends into the slot 26 in each of the supports and into the slot 62 in each of the struts 48 and 50 and the sections of the anges 30 intermediate the flanges 54 and 56 on each of the struts 48 and 50 are crimped or otherwise deformed after the flange 30 is inserted in the slots so as to prevent relative movement between the louver, the supports 14 and 16 and the struts 48 and 50. With such a construction, the struts 48 and 50 may be xed to the mating supports without the use of screws, rivets or similar fastening devices and with a minimum of tools, time and labor.

At a position near, but spaced from, the opposite ends of the struts 48 and Si), aligned apertures 61 are formed in the anges 54 and 56 of each of the struts in order to facilitate fastening such ends of the struts to the wall.

The uppermost louver 63 adjacent the upper end portions of the supports i4 and 16 is preferably of the cross sectional contour illustrated in Fig. 2. The lower edge portion 64 of the louver 63 is shaped similarly to the corresponding portion of the louvers '2.8 so as to spacedly overlie the curved portion 34 of the adjacent louver 28 and the other edge portion 66 of the louver 63 is bent downwardly so as to extend in a direction substantially parallel to the plane of the wall 10, the edge portion 66 being joined to the portion 6d of the louver by an angularly extending central portion 68. With such a construction, a triangularly-sectioned groove 70 is defined between the wall 1G and the central portion 68 and such groove may be filled with a conventional sealing or calliing compound '72 so as to seal the junction between the uppermost louver 63 and the wall 1t).

The inner end portion of each of the supports 14 and 16 and the struts 48 and 58 is secured to the wall 10 by a screw 74. Each of the screws 74 includes a threaded shank portion 76 and an integral, rectangularly sectioned, block-shaped head '78 having a transversely extending passageway Si) therein adapted to accommodate the shank of a bolt 82. In the installation of the awning, the uppermost louver 63 is located in the desired position above the window opening 12 and fastened to the wall with two of the screws 74, the shank 76 of such screws passing through apertures provided in the portion 66 of the louver 63 at a position spaced from each end thereof. The screws 74 are tightened so that the axis of the passageway 86 in the head '78 of each screw 74 is substantially horizontal and the upper ends of the supports 14 and 16 are then fitted over the heads 78 of the screws '74 so that the heads of the screws are positioned intermediate the anges 20 and 22 of the supports with the openings 29 in Such flanges aligned with the passageway 80 in the head of each screw. The bolt 82 is then inserted through the apertures 29 in the flanges 20 and 22 of the supports and the passageway 80 in the heads of the screws and nuts 84 are tightened thereon to draw the flanges 20 and 22 up against the heads 78 of the screws 74.

rIhe inner end portions of the struts 48 and 5() are secured to the wall in a similar manner, the bolts 82 passing through the apertures 61 provided in the flanges 54 and 56 of the struts and the passageway 80 in the head 78 of the screw 74, and holding the anges 54 and 56 against the screw heads 78. In the preferred embodiment illustrated, washers S6 are used between the screw heads 78 and the wall 10.

While only one preferred embodiment of the invention has been shown and described, it will be understood that various changes and modifications may be made without departing from the spirit of the invention.
