With continuedreference to the drawings, the

4improved awningcomprises, in general, vaframe f I Ii, atop wall Il' disposed .above theirame, a front Wall I2 continuous withv the topwall and A'secured to the front'o'r` ther frame, ,a'pair of'jside walls I3, a supporting structure Mfor theupper "edge of lthertopwall Il and a hood I5 disposed 'above'the supporting structure I4 to exclude'rain from va Ventilating passage provided by thesupport structure.

The frame I is particularly illustratedV in .Figures 2, 7, 8 and l0 and comprises a front bar I6 of substantially square, tubular-formation, a pair of substantially horizontal side bars I1 of the same form as the front bar and each secured at one end to a corresponding end of the front bar, and a pair of inclined side bars I8 which are also of the same form as the front bar and, each of which is secured at one end to a corresponding end of the front bar IE. The horizontal bars l1 are substantially perpendicular to the front bar iS and each inclined bar i8 is disposed at an acute angle to the corresponding horizontahbar Il.

The horizontal side bars Il are provided'at their ends opposite the front bar I6 with respective clips I9 for attachment to the window opening surrounding portion of a building wall. to

which the awning is attached, and the ends of vthe inclined frame bars I8 opposite the "front bars i6 are connected to the corresponding` ends of a flat plate 28 which is attached to the building wallimmediately above the window openngand constitutes a part of the support structure generally indicated at I4.

The top wall of the awning;V as particularly illustrated in Figures 1, 2 and 6, comprises a plurality of elongated panel strips 2l having par- .allel edges and arranged in sideeby-side relation- .strip to.V provide a slot `along the .inner side of .each panel .strip flange. Eaehcap strip 22` is .agenerally tubularmember of substantially rec- Ltangular cross-.sectional shape but Vpreferably having bevelled outer corners 25 and having a pair of parallel, centrally-located,.internalanges v215 receivable in the slots provided by the-reversed portions 24 of two adjacent panel strip nanges 23, as is clearly illustrated in Figure 6. Eachcap strip may be operatively assembled 'with the. corresponding .adjacent panel strips, by inserting :the internal flanges 2B at onejendlof V.the cap.. strip .intothe adjacentnends of the slots provided between .the panel strip anges 23"-'and the corresponding reversed'flange portions-24 and sliding the capstriplongitudinally ofth'e'panel strips until the cap strip is coterminous with the panel strips, the cap strips being started at the ends of the top wall panel strips from which the front wall I2 depends.

The front wall I2 comprises continuations of the top wall panel strips and cap strips but the internal flanges 26 of the cap strips are cutaway, as clearly illustrated in Figure 11 so that when the end portions of the cap strips forming the front wall are bent downwardly the flanges 26 may be snapped under the reversed portions 24 of the panel strip flanges 23.

The panel strips are secured to the frame front bar I 6 by screws 21 inserted through portions of the panel strips covered by the corresponding cap strips 22 before the cap strips are snapped down into place, suitable apertures 28 being provided in the inner wall portions of the cap strips to receive the heads of screws 21. These screws are tapered, spirally-threaded screws conventionally used to secure sheet metal parts together. After the end wall portions of the panel strips 2| have been firmly secured to the front frame bar I6 the front wall portions of the cap strips are snapped into place and secured to the panel strips by screws 29, Figure 1l, inserted through the panel strips into the inner wall portions of the cap strips immediately below the frame bar I6.

The frame bars may be secured together at their ends by suitable means such as illustrated in Figure 8, wherein a U-shaped clip 30 has an apertured web portion seculed to one of the bars by a screw 3| and a pair of legs received in the end of the other bar and secured thereto by screws 32.

The outer portion of top wall II is supported above the inclined frame members I8 by the front wall I 2, as is clearly apparent from an inspection of Figure 2 and the inner or upper edge of the top wall is supported above the inclined side bars of the frame by the supporting structure I4. In addition to the plate 2D this supporting structure comprises a support strip 33 having along its lower edge an outwardly extending flange 34 provided with a reversed portion 35 which is inclined to the flange 34 at an angle substantially equal to the acute angle between each frame side bar I1 and corresponding inclined bar I 3. The inner edge of the top wall II rests upon the reversed portion 35 of the support strip flange and a plurality of tongues 3S struck out of the support strip overlie the upper surface of the top wall and are secured to the top wall cap strips by screws 31, as particularly illustrated in Figure 9, the panel strips of the top wall being secured to the reversed portion 35 of the flange by similar screws 38. Strip 33 and plate 20 are provided with registering apertures and suitable screws or bolts 39 extend through these apertures and into the building wall to carry the support strip 33, suitable tubular spacers 40 respectively surrounding the screws 39 between the support strip 33 and the plate 20 to space the support strip from the plate and provide a Ventilating air passage between the inner or upper edge of the top wall II and the building wall contacting plate 20.

The upper edge of the support strip 33 extends above the top edge of the top wall II and the hood I is provided along its outer edge with a depending flange 4I which overlaps the upper edge of support strip 33 to provide a labyrinth passage leading to the top of the Ventilating space between the support strip and plate 20 to prevent rain or other moisture, such as snow and sleet, from being driven under the hood and downwardly through the Ventilating passage.

At its upper edge the hood I5 is provided with a flange 4'2 apertured to receive screws 43 by means of which the hood is secured to the building wall in operative position above the upper edge of the awning top wall I I.

The hood I5 is also provided with downwardly extending end walls 44, Figure 5, which close the opposite ends of the Ventilating passage.

Each end wall I3 comprises a plurality of flanged panel strips 45 and cap strips 46 of the same construction as described above in connection with the top wall II and interlocked in the same manner.

The panel strips and cap strips of the end walls are cut off to terminate along a line spaced just below and substantially parallel to the corresponding horizontal frame side members I1, the bottom edges of the panel strips being preferably concavely curved, as indicated at 41, as are also the panel strips of the front wall I2. At their upper ends the panel and cap strips of the side walls are diagonally cut to terminate substantially flush with the upper surfaces of the corresponding inclined frame side members I3, which places the upper ends of the side walls below the under-surface of the top wall I I. The two marginal top wall cap strips 2I are different from the intermediate cap strips 2| in that they have depending outer wall portions 49 and only one internal flange 26. The depending outer wall 49 of each marginal cap strip 2| extends downwardly below the upper edge of the corresponding end wall I3 and overlies the outer surfaces of the corresponding cap strips 46 to which it is secured by screws 50. This construction provides Ventilating spaces between the side wall cap strips which extend Within the depending side walls 49 of the marginal top wall cap strips and to the under-surface of the top wall II. Air flowing through these last-mentioned Ventilating spaces cools the end walls of the awning and ows along the under-surface of the top wall to the Ventilating space between plate 20 and supporting strip 33 and out of the awning beneath the hood I 5.

To facilitate mounting of the awning the two horizontal frame side members I1 may each be formed in two telescopically associated portions, as indicated at 52 and 53 and particularly illustrated in Figure 12. By means of this telescopic construction the awning may be adjusted to the desired angle and the length of the lower or horizontal frame side bars adjusted to accommodate any variations in the angle of the awning or any qualities in the surface of the building wall and the two portions then secured in fixed position relative to each other by a suitable means such as the screw 54.

The invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are, therefore, intended to be embraced therein.
