Wagner, Riverside, Calif, assign'ors, by mcsne assignments, to National Distillers and Chemical Corporation, a corporation of Virginia Filed Oct. 3, 1955. Ser. No. 537,942 1 Claim. ((Il. 20-575) This invention relates to metal awnings and similar overhead shelter structures, such as canopies, umbrellas, and the like, and its primary object is to provide a new and improved rigid, ventilated awning or the like embodying roll-formed sheet metal components which can be assembled quickly and easily, with a minimum of tools.

Another important object of the invention is to provide a system of awnings wherein the same panel, or slat, can be used to make either a vertical panel awning or a horizontal panel awning, by mounting the panel on one or the other of two types of stringers. Thus, with one or two additional structural members for braces and the like, it is possible to manufacture a variety of awnings to cover practically any type of window and to fit any architec tural treatment.

Another object is to provide an awning panel of simple cross sectional shape which can be roll formed from prepainted, coiled strip in the awning manufacturers plant, using relatively inexpensive machinery. This makes possible considerable savings in freight charge for shipping material from the strip factory to the awning manufacturers plant, owing to the fact that coiled strip is a compact, high density commodity taking the lowest freight rate, whereas formed panels are a bulky, light weight commodity taking a much higher freight rate based more on volume than on weight.

A further object of the invention is to provide an awning of extremely simplified assembly, wherein most of the elements slide together or snap into place without requiring screws or other fasteners, yet which hold together with a positive grip that resists the racking and twisting forces exerted by winds of near-hurricane velocity. One important advantage of this feature is that most sizes of awnings can be put up by one man alone, which means lower labor cost for installation. The present invention minimizes the cost of assembly, which is normally the principal cost of an awning.

Still another object of the invention is to provide an awning that is particularly adapted to being shipped in knocked down condition and assembled on the job by unskilled labor.

A further object of the invention is to provide a new and improved method of mounting awnings on a wall or other supporting structure, which is simple, quick to install, and extremely strong.

The foregoing and other objects and advantages of the present invention will become apparent to those skilled in the art upon consideration of the following detailed description of the preferred embodiment thereof, reference being had to the accompanying drawings, wherein:

In the drawings, the vertical panel awning of FIGURES l to 7, inclusive, is designated in its entirety by the reference numeral 10, and is seen to comprise an inclined top 11 terminating at its lower end in a valance 12, and sides 13. Both the top 11 and sides 13 are made up of assemblies of elongated sheet metal panels, 15 and 15', mounted on stringers 16. The panels 15, 15' are arranged parallel to one another and face alternately in opposite directions. In the top 11, the panels are spaced apart vertically, with the upper panels 15 facing downwardly, and the lower panels 15 facing upwardly, while the sides 13 consist of inwardly facing outer panels 15, and outwardly facing inner panels 15.

Each of the panels 15, 15 is formed from flat sheet metal strip, with the longitudinal edges thereof curled roundly at 21 toward the same side of the panel thru an angle of between and 180; the preferred angle being approximately as in the drawings. With the edges thus curled up from the midsection, the panel 15 has the cross section of a shallow, flat-bottomed channel. The preferred method of carrying out the invention calls for shipping the flat, pre-painted strip in coils from the strip manufacturer to the awning manufacturer who, in turn, runs the strip thru a roll-forming machine that curls the edges at 20 and cuts the panels to length. In this manner, considerable economy is effected in shipping the panel material to the awning manufacturer, since the coils of flat strip are extremely compact for the weight, and therefore enjoy a favorable freight rate as compared to formed panels, which are extremely bulky to ship.

The stringers 16 are likewise formed of sheet metal which has been formed to the generally U-shaped cross section shown in FIGURE 3. The longitudinal edges of the stringer are cut out, as best shown in FIGURE 6, to provide vertically spaced upper and lower seats 21 and 22, respectively, shaped to receive upper and lower panels 15 and 15', respectively. Each of the upper seats 21 is fiat on top, with rounded end, projecting portions 23 which overhang the ends of the adjacent lower seats 22. The upper seats 21 fit into the channel of the upper panels 15, and the end portions 23 project into and snugly engage the edge rolls 20.

The lower seats 22 are flat on the bottom, and their ends are curved upwardly at 24 to fit snugly around the outside of the edge rolls 2!) of the lower panels 15'. The bottoms of the overhanging end portions 23 of the upper seats are cut away at 25 to provide clearance for the edges of the lower panels.

The panels of the top section 11 are assembled on at least two, and in most cases three or more, stringers 16 which are disposed horizontally and extend transversely of the panels, with the channel opening upwardly and outwardly. The lower panels are assembled on the stringers by sliding them endwise thru the lower seats 22. At this point, the lower panels 15' are locked to the valance stringer by means of a locking tool (not shown) which engages the curled edge of the panel between the sides of the stringer and bends a tab 26 outwardly. The tabs 26 prevent lengthwise shifting of the lower panels with respect to the stringer. The valance 12 is then bent down to the desired angle, for which purpose the curled edges of the panels have V-shaped notches 27 cut out. Next, the panels 15' are locked to the upper stringers by bending out tabs 26, after which the upper panels 15 are snapped down over the upper seats 21.

The panels of the side sections 13 are likewise assembled on two or more stringers 16, and the side sections are then joined to the top section 11 by interfitting the adjacent ends of the bottom stringers, as shown in FlG- URE 5, and passing a split cotter pin 29 thru aligned holes in the sides of the stringers, which are formed by punching out knockouts 30 that are provided at spaced intervals. The knockouts 30 are incompletely sheared holes punched in the stringers, and require only a moderate amount of pressure with the point of a nail or other tool to push them out. In order to interfit the ends of the stringers 16, one of the stringers is notched out at 31, and the sides thereof are spread slightly to receive the end of the other stringer.

As best shown in FIGURE 4, the top ends of the side section panels extend under and are engaged by the outer edge roll of the end panel 15 on the top section 11. The outer panel 15 of the side section 13 is also engaged on its inside surface by the end 32 of the top section stringer 16. The top edge of the side section 13 is thus confined between the edge roll of the outer panel and the end of the stringer 16, and is thereby held against lateral displacement.

The awning 10 is mounted on a wall 33 or other supporting structure by means of brackets 34 and a supporting member 35 (see FIGURE 3). The brackets 34 are secured to the wall by screws 36, and are shaped to receive the end of the bottom stringer 16 of the side sections, to which they are attached by cotter pins 37. The supporting member 35 serves as both support and flashing for the awning, and to this end is provided with a vertical back 40, a downwardly inclined drip shelf 41 at the top edge thereof overhanging the ends of the panels, and an upwardly opening channel 42 at the bottom edge to receive the top stringer 16 of the top section 11. The member 35 is secured by screws 43 to the wall, and the stringer 16 is held down in the channel 42 by a sheet metal screw 44. The distance between the adjacent edges of the drip shelf 41 and the channel 42 is slightly greater than the overall height of the upper stringer 16 and attached panels, which permits the stringer to be inserted under the drip panel and seated in the channel.

The vertical panel awning described herein can be assembled quickly and with ease, using a minimum of tools and labor. The structural members are all rollformed sections, which are light and inexpensive, and a minimum of fasteners are required to assemble the components.

One of the important features of the invention resides in the fact that the panels 15 can be used to make up a horizontal panel awning of the type illustrated at 49 in FIGURE 8, as well as the vertical panel awning of FIGURE 1, by merely attaching the panels to a different stringer and using one or more additional structural members or attachment brackets. For an understanding of the construction of the horizontal panel awning .49, reference is had now to FIGURES 8 to 15, inclusive.

As best shown in FIGURES 10 and 11, the panels 15 are mounted on two laterally spaced, inclined stringers 50. The stringers 50 are preferably made up of sheet metal, formed into deep U-shaped channels, the sides of which diverge slightly as shown in FIGURE 11. The

longitudinal edges of the stringers are cut out to form a plurality of equally spaced, parallel seats 51 for the downwardly opening panels. Each of the seats 51 is inclined to the longitudinal axis of the stringer at an angle such that the top surface of the panel 15 is inclined downwardly at approximately 20 from the horizontal, so as to shed rain and exclude the slanting rays of the sun when the latter is low in the sky. Also, the lower end of each seat overhangs the upper end of the seat below, so that there is a certain amount of overlap of the panels. Each seat has a straight edge portion 52 that lies fiat against the bottom of the panel, and rounded end portions 53 and 54 that extend into and engage the curled edges 20 of the panel. The seat 51 is undercut deeply at its lower edge, as shown at 55, to permit the curled rear edge of the next lower panel to be inserted behind and hooked under the rear end 53 of its seat.

The two stringers 50 are attached at their upper ends to the wall or window frame, by means of U-shaped brackets 5'6, that are connected to the sides of the stringer by sheet metal screws 57, which are screwed into knockcuts 58 provided in the stringer. The lower ends of the stringers are held out from the wall by means of horizontal braces 60. The braces 60 are U-shaped channels, which open upwardly, and the outer end of the channel receives the bottom end of the stringer 5t and is attached thereto by sheet metal screws 61 that also screw into the knockouts 58. A U-shaped bracke 62 is secured by sheet metal screws 63 to the other end of the brace, and this bracket is mounted on the wall or window frame to support the awning.

The horizontal panel awning 49 may be made up without side sections, in which case, the construction as described to this point, is complete. If side sections, or returns, are desired, they may be added to the awning by attaching a downwardly opening, U-shaped channel member 64 to the underneath side of the stringer 50 using sheet metal screws 65. Vertical panels 15a are then inserted into the channels 6% and 64, said panels facing alternately inwardly and outwardly, as best seen in FIGURE 12. The bottom ends of the panels 15a are cut off square to fit within the horizontal brace channel 60, while the top ends thereof are cut to the same angle as the upper channel 64. The panels 15:: overlap one another, and can be telescoped together or extended, as necessary, to fill the triangular area enclosed by the mem bers 60, 64 and the vertical wall or window frame. If it is desired to make an awning of such dimension that the individual panels would be too long for convenient handling, two or more panels of shorter length may be joined together, as shown in FIGURE 15, to make an extended panel of any length. In this case, one of the panels 15b is snapped over the end of the other panel 150. The curvature of the edge rolls 20 allows them to fit snugly over one another, to make a tight junction.

The many advantageous features of the present invention are believed to be clearly apparent from the fore going description. While we have shown and described in considerable detail what we believe to be the preferred form of the invention, it will be understood that various changes in the shape and arrangement of the several parts may be made without departing from the scope of the following claim.
