This invention comprises novel and useful improvements in a rigid awning and more specifically pertains to an awning of aluminum or other metal which is provided with a ventilating or air circulating means.

The principal objects of the present invention reside in providing an awning which may be readily constructed of rigid sheet metal; which may be easily and readily assembled or disassembled by unskilled labor with a minimum of efiort; wherein a novel and efficacious means is provided for insuring the circulation of air from under the awning; wherein the parts of the awning may be secured in a water-tight manner to a supporting surface; and wherein a structure is provided by effecting the principles of this invention in a variety of inexpensive arrangements.

These, together with variou ancillary objects of the invention which will later become apparent as the following description proceeds, are realized by this invention, various embodiments of which have been illustrated, by way of example only in the accompanying drawings, wherein:

Figure 1 is a perspective view showing one form of construction for practicing the invention, parts being broken away to more clearly illustrate the construction of the same;

Figure 2 is a View similar to Figure 1 but showing a modified form or arrangement of the awn- 111g;

Figure 3 is a perspective view illustrating yet another form of construction of one of the elements of the awning;

Figure 4 is a view similar to Figure 3 illustrating a fourth form of awning roof;

Figure 5 is a fragmentary detailed view in section showing one manner of attaching the side plates of the awning assembly to a window frame;

Figure 6 is a view similar to Figure 5 but showing a modified form of attachment; and,

Figure 7 is a view similar to Figure 5 but showing a. third alternative form of attaching the side plates to the supporting surface.

Referring now more specifically to the accompanying drawings, and reference being made first e to Figure 1, it may be seen that the awning forming the subject matter of this invention is composed of a plurality of aluminum sheets or other thin sheet metal or similar material, which may be readily assembled to form the complete awning or may be removed as desired for compact storage and transportation. In accordance with the invention, a pair of complementary generally triangular end caps or plates I0 have their front and rear ends l2 and M respectively inturned in parallel relation and perpendicular to the surface of the sides of the member ID, as shown clearly in Figure 1. By means of screws I 8 or other suitable detachable connecting means, the end caps ID are secured by the rear flanges I4 ,to any suitable supporting surface, such as for example, the facing plate of a window. Detachably mounted in any suitable manner and supported upon the end caps I0, is the awning roof 22 which has its lateral end downwardly inclined along their marginal edges as at 24 in order to snugly embrace the inclined edges of the triangular end plates 10. As will readily be seen, the roof 22 is disposed in a downwardly inclined position relative to the supporting surface 20, in a manner conventional with awnings. The lower edge of the roof 22 is provided with a downwardly extending marginal flange portion 25 to which is secured in any suitable manner the aforementioned inturned edges l2 of the end plates It, to detachably unite in a rigid manner these portions of the members.

At its upper edge, the roof 22 is provided with an upwardly and vertically extending wall or rim 26, this rim being spaced parallel to the supporting surface 2!! to provide an air vent space therebetween.

The assembly is completed by means of a storm cap 28 which as shown, is adapted to slope downwardly from the supporting surface to which it is secured by an upwardly turned flange or rim 3B removably secured to the window frame 20 as by detachable fastening means 32. The storm cap 28 is adapted to overlie the above mentioned vent space and the upwardly extending rim portion 26 and at its outer edge is provided with a downwardly depending skirt or apron 34 whose lower extremity is inwardly turned as at 316 into close proximity to the vertically disposed rim 2t, to provide air vent space therebetween, this flange 35 comprising a strengthening means.

It is contemplated that the upwardly extending flange SE! of the storm cap 28 will be attached in a water-tight manner to the window facing 26, to prevent the entrance of moisture therebetween, while the rear flanges it of the triangular end caps it are similarly secured in a water tight manner to the window frame 2 The operation of the device is as follows:

The rays of the sun strike the inclined roof 22 of the metallic awning, heat the same and the thereunder, and by reason of the inclined siufa-ce cause an upward movement the air which escapes through the vent space between the upwardly standing flange 26 and the side of the supporting surface 20. This heated air rises into the space below the storm cap 28, and escapes between skirt 34 and rim 26 and also from the open ends thereof.

It will thus be seen that the assembly comprises but four members, the two end caps it the awning roof 22, and the storm cap 28, which are detachably connected to each other and may composed of similar elements mounted in a similar manner upon the "frame 33 in which is slidably mounted window. sash as indicated at iii.

gplates 152 similar to those indicated at il in ihgure 1, are provided :and have rearwardly extending supporting flanges 44 retained upon the trance as by means aof detachable fasteners 51E, while the forward :end of the triangular plate gin'emhers are inwardly flanged :as at and are iietachably connected to embrace and engage .b" :nreuns .of the :ho'lts 5.6 or the like, the down diy aextending flange portion 152 of the awning roof member :whichis downwardly inciine'd relative to the supporting surface. As so v:far described, tthis construction is substantially ,entical with that described :in Figure 1, "although as will be noted "at '55 the lower edge of the send ca s 52 depending ii'ange 52 of the roof 5% be scalloped or :notched.

As 'shownbyithe top portion 58 o'fthe side caps the upper :edge of the roof it terminates in -l-=.=-;terally spaced relation to the supporting surface 33, to provide an air vent as in the forer l' Secured by means of se 'tachable fasteners 6t: by its vertically :upwardly extending flange portion 52, is a downwar ily clined storm cap E i. which is adapted to overlie the air vent between the supporting surface and the :uppered e of the roof E k-and which storm cap is providedwith a downwardly and gener lly perpendicularly disposed 'flange member '55 WI (311 is provided with suitable openings or louvers and whose lower edge is extended to *constitute the roof 5t? either-by an angular or a 'rounued portion E's. 'As'inthe preceding embodiment, the storrncap 54 is spaced vertically above the air vent above rnentionen, and isopen atits ends to 'facilitatethe flowof airoutwardly therefrom. V

The operation of this form of the invention is identical with that eboveset forth, but it "will be .ioted "the stormcap fi i is provided with additional air circulating openings '58 which open doii nwardly upon the roof 5 3.

As shown in Figure 3, in some installations it be preferredto support the downwardl inclined roof member it with its vertically disposed lower ge'lz and its vertically disposed upper flange at its upper orrear end in order to take some of the weight off of'the side caps-particularly in the case of large awnings. For this purpose, theupper edge of the vertical flange is may be'rolled forwardly to provide a head as at 16 through which may extend a supporting rod indicated in phantom lines at l8, and mounted in any suitable manner upon the supporting surface, to thereby support and carry some of the load of the upper'end of the roof 10.

Alternatively, as shown in the form of the roof 8i depicted in Figure 4, the rigidity of the roof may be enhanced or augmented by forming the forward end flange 82 in an angular manner as indicated at as upon the lower end of the roof. This arrangement results in a fluted or corrugated and angularly disposed end .82 which greatly increases the lateral rigidity of the roof. At its upper end, the roof 90 has its vertical flange 86 reinforced against bending in the middie by means of a transversely extending angularly-disposed and inturned horizontal surface 8-8 whose forward edge is then turned downwardly in vertical plane as at 2%. As will be readily understood, either construction of Figures 3 or 4 may be interchangeably employed with the storm caps of Figure l. V A variety of equivalent means may be employed for effecting a water-"tight seal between the end caps shown Figures 1 and 2, and the supporting surface which may conveniently be composed of the facing plate 33 of the window sash 4. For this purpose, as shown in 'Figurefi, an end cap 82 may be provided with afla'terally extending flange portion dd adapted to snugly abut against the forwardsurf-ace of the supporting surface andis provided with a .rearwardly extending mar inal flange '56 which embraces the er edge of the frame 38 on theside adjacent the window ti], and is detachably secured thereto as by screws .58. in this embodiment, it will be seen that the end caps may he conven- .iently attached directly .to the window facing in a water-tight manner .upon two edge surfaces thereof. 7 a

As shown in Figure .6, the end cap tflflcmay be secured to the supportingsurface of the window facing 38 by means of an inwardly -inturned;.pergpendicular flanged .end portion 482 detachably engaging the supporting surf ace :as by a fastening means E i. This form of attachment is substantially identical with that shown in Figures 1 and 2.

Alternatively, in, lighter installations, the end caps Hit, as shown in Figure 7, may be detachably secured upon the innersurfacelof the window facing 38 and adjacent the window sash #9 by :means of appropriate detachable fastening means Hi8 which secure the straight rear-ward edges of the end caps [86 to the supporting surface 38.

It is to be clearly understood that various suitable modifications and equivalents may readily be employed within the broad principles of this invention, and that the invention is not limited to the particular structures and arrangements shown in the variousfigures of the drawings. It is notintended that this invention resides broadly in "the provision of metallic window awnings; or even in the sectional construction which permits the ready attachment to or removal from window frames. However, the arrangement in a metallicawning, whereby an air vent and circulating space is provided at the top 'of the :roof ofxtheawning, together with the storm cap thereover which facilitates and enhances the circulat- "ing 'effectof the awning, form the fundamental lents may be employed falling within the scope of the appended claims.
