WINDOW AWNINGS Filed March 8, 1954 Grover C Man/7 Len 4020/7 INVENTORS ATTORNEY forming a volute-like clamp gage in an undulation of a WINDOW AWNINES Grover C. Mann and Len Acton, Dallas, Tex. Application March 8,1954, Serial No. 414,663 Saints. (Cl. 20-575} This invention relates to awnings and more particularly to ventilated awnings for windows.

The principal object of the invention is to provide a window awning designto exclude all but reflected suns rays and rain but to admit air to preclude entrapment of hot air under the awning and with these advantages in view, the invention consists of mounting brackets in the form of straps, preferably of aluminum, which are adapted to be disposed, one on each side of a window and inclined with respect thereto, each strap having reverse bends therein at longitudinally spaced intervals adapted to conformably encorrugated cover panel of the awning, thus to hold a panel at its upper edge in underlying relationship with the lower edge of an adjacent higher panel from which it is spaced to admit air between the panels.

Another object of the invention is to provide a ventilated awning which may be compactly stored and shipped in dismantled condition for ready assembly and installation by a purchaser and further, an awning which is not only ventilated but one which permits the use of translucent corrugated plastic panels which exclude glaring sun rays from a room while at the same time permitting entrance of diffused light.

Other objects will become manifest as the description proceeds when considered with the annexed drawing wherein:

Figure 1 is a fragmentary to perspective view of a window awning constructed according to the present invention.

Figure 2 is a sectional view taken vertically through one of the supporting brackets.

Figure 3 is a fragmentary perspective view of a slightly modified form of the invention, and

Figure 4 is a fragmentary side elevational view of one of the brackets of the form of the invention shown in Figure 3.

Continuing with a more detailed description of the drawing, reference is primarily made to Figures 1 and 2 wherein numeral denotes a metal strap, preferably of aluminum, having its upper end 11 to lie in parallelism against a supporting surface, such as a side of a window frame, and secured thereto by nails or screws driven through holes 12 therein. The supporting portion of the bracket formed by the strap 10 is disposed at an angle to the supporting structure and is formed with a plurality of reverse bends or volutes 13. These volutes each are defined by curving the strap rearwardly and upwardly, forming a circle 14 whose outer diameter substantially equals the radius of the uppermost undulation 15 of a corrugated cover panel 16, preferably molded from translucent plastic material but which obviously can be formed of other material. The strap 10 is bent upon itself and continues downwardly in conformity with the circle 14 to a point spaced below the first volute 13 where the volute is duplicated and so on to a predetermined point to define the lower extremity of the awning whereat 2,752,645 Patented July 3, "1 956 M the strap 10 is turned upwardly and again towards-its supporting surface and, at intermediatepoints, the strap is bent into any one-of many ornamental forms, one

10 which extends from the lower-edge of the :aWnin-gtoward the supporting surfacelies partly in the :channels19 and is secured therein by screws 22.

The cover panels 16 are, as stated previously, .corrugated andmade preferably oftranslucent plastic material. The ends of the uppermost panel are secured to the opposed brackets 16 by metal screws 23 threaded through holes 24 made in the brackets and the lower edge of this panel extends past thevtopmost volutes 13 in the brackets. To securethe upperedges of the next succeeding lower panels, that portion of the bracket-subjacent. each volute'13 is sprung downwardly to create a spacebetween the circle 14 and thesu'ojacent strapzportion, whose confronting surfacesxconform' to the top and bottomsurfaces of the uppermost undulation ;-15 of the panel and which is insertedinto-the said space, whereupon the subjacent portion of the strap-resumesthe norrnal position shown, clamping the upper edge of the panel. The ends of the panel below the volutes 13 are secured by metal screws 25 to the brackets 10, which have holes 26 to accommodate the screws.

The lower edges 27 of the panels 16 extend downwardly in overlapping relationship with the clamped upper edges of all but the uppermost of the panels and by virtue of the volutes 13, the adjacent edges of the panels are spaced apart, admitting air but excluding rain and direct sun rays.

In Figures 3 and 4 is shown a modified form of the invention. Angular supporting brackets 27 are formed of metal straps whose upper ends 28 are bent into parallelism with a supporting surface and have holes 29 to receive nails or screws for securing the same to said surface.

The modified form of awning supporting brackets 27 are designed to hold the cover panels 30 without the aid of screws. To accomplish this, each strap has a double reverse bend at longitudinally spaced intervals through out its panel supporting portion, the uppermost of such bends terminating in the attaching leg 28. Each double reverse bend, except at the top and bottom, is made by turning the strap rearwardly onto itself and thence forwardly onto the first bend to create a receptacle 31 into which is inserted the lower edge 32 of an adjacent panel 39. The strap is then bent rearwardly under the receptacle 31 and again forwardly, defining a receptacle 33 adapted to receive the upper edge 34 of the next lowest panel 30. The bends in the straps are curved so that the

receptacles

31 and 33 will likewise be curved to conform to the curve of the undulations of the corrugated panels which engage in the receptacles, thus to hold the panels against displacement on the supporting brackets.

The upper edge 35 of the topmost panel is clamped by bending the strap forwardly to define a receptacle 36 to receive said upper edge, thence rearwardly onto the first bend and downwardly to form the mounting leg 28.

The lower edge 37 of the lowermost panel 30 is clamped by bending the strap rearwardly to define a receptacle 38 of said edge 37, thence forwardly onto the first bend and again rearwardly toward the supporting surface as a brace 39, which latter may be formed into a variety of differand, as in the preceding case,

by additional in the earlier ent ornamental designs and supplemented reinforcing means such as the channel 19 described form of the invention.

The adjacent edges of the panels 30 are in overlapping relationship and spaced apart to admit air therebetween the panels 30 may be either translucent or opaque, as described.

Manifestly, the construction as shown and described is capable of some modification and such modification as may be construed to fall within the scope and meaning of the appended claims is also considered to be within the spirit and intent of the invention.

What is claimed is:

1. A window awning comprising supporting brackets, each consisting of a metal strap disposed at an angle to a window and having formed therein at longitudinally spaced intervals a series of reverse volutes, a plurality of cover panels having corrugations traversing said supporting brackets and whose edges are relatively overlapping, said volutes each defining arcuate receptacles conforming to the curvature of and clampingly receiving the adjacent edges of upper and lower panels to hold the same against displacement and means for securing said brackets to supporting surfaces.

2. A window awning comprising supporting brackets, each consisting of a metal strap having therein at longitudinally spaced intervals a reverse volute defining an arouate receptacle, a series of corrugated panels supported by said brackets, the lower edge of one panel extending downwardly beyond the upper edge of an adjacent panel, said upper edges being clampingly engaged in said receptacles and held by said volutes in spaced relationship to admit air therebetween.

'3. An awning comprising angular supporting brackets and a plurality of cover panels in which the lower edge of one panel overlaps the upper edge of the next lower panel, said supporting brackets each consisting of a metal strap having reverse volutes at longitudinally spaced intervals formed by bending said strap upon itself to define arcuate receptacles for clampingly receiving the upper edges of said panels, and means for securing said brackets to a supporting surface.

4. The structure of claim 3, said volutes being in a plane perpendicular to said strap to hold the adjacent edges of said panels in spaced relationship.

5. In a window awning, a supporting structure and a plurality of corrugated cover panels the lower edge of one panel extending downwardly beyond the upper edge of an adjacent panel, said supporting structure comprising longitudinally spaced metal straps each having a multiple bend at longitudinally spaced intervals defining arcuate receptacles matching the curvature of the corrugations in said panels and adapted to clampingly receive the upper edges of adjacent cover panels to hold the same against relative displacement on said supporting structure and means for securing said structure to a supporting surface.
