The side walls of-the pans are conventionally manufactured to provide an interlocking relationship which prevents leakage of water between the pans. One end of all of the pans is then supported in an elevated position so that any water falling on the structure will run by gravity in a direction lengthwise of each one of the pans. Awning structures of this type are now widely used, particularly in conjunction with mobile homes.

The elevated end of the awning structure is usually supported from the wall of an appurtenant structure, such as a mobile home. Additional structural elements are then needed in order to support and seal the upper end of the awning, and these additional elements may include a mounting strip and a hat assembly.

In the prior art the hat assembly has generally included an elongated hanger which is supported from the mounting strip or rail and which in turn supports the under surfaces of the awning pans; and a flashing which extends above the elevated pan ends.

Based upon careful observation of the conventional upper end support for an awning structure of the type described, I have concluded that improvement would be desirable and is possible.

One object of the present invention, therefore, is to provide an improved assembly for supporting the elevated end of an awning structure.

Another object of the present invention is to provide a novel method of assembling an awning structure, particularly the hat assembly thereof.

SUMMARY OF THE INVENTION According to the present invention an elongated hanger which extends along and underneath the elevated pan ends is still used, the same as in the prior art. This hanger is supported from the wall of the appurtenant structure by means of a mounting strip or rail but the hanger and mounting strip are uniquely designed to provide a leak-proof pivotal locking arrangement. According to my invention a flashing is also used to extend above the elevated ends of the pans, and this flashing is constructed in a unique and novel manner.

Furthermore, in accordance with my invention the method of assembling the awning structure, and particularly the hat assembly thereof, is a great deal different than any that has heretofore been known.

More specifically, according to my invention, the flashing is made to interlock directly with the hanger. The hanger is provided with a joining portion, located at the upper corner of the elevated ends of the awning pans, which joining portion is laterally curved through an angle of at least about 180. The flashing is made as a flat sheet which covers the upper surface of the elevated ends ofthe pans, and also includes ajoining portion integrally formed with one lateral edge and which is adapted to be received in a nested and pivoted relationship within the joining portion of the hanger. The joining portion of the hanger locks in a similar manner with an arcuately curved recess of the mounting strip.

Furthermore, according to my invention, it is preferred to construct the flashing in sheets or sections, so that a number of flashing sheets are arranged in a longitudinal series to be supported from a single elongated hanger. Furthermore, the flashing, sheets are constructed in such a way that their ends will overlap, thus providing an effective water tight seal.

One advantage of my invention is that an effective water-tight seal is achieved, which has not been possible with the type of upper end support utilized in the prior art awnings.

Another advantage of my invention is that the installation may be completed without the necessity for the installer to walk on top of the awning structure. The attendant risk of damage to the structure is thereby avoided.

Still another important advantage resulting from my invention is that the labor time required for installing the awning structure is significantly reduced.

DRAWING SUMMARY FIG. 1 is an eleva-tional cross sectional view of an awning structure in accordance with the present invention;

FIG. 2 is a cross sectional view taken on the line 22 of FIG. 1;

FIG. 3 is a fragmentary cross sectional view taken on line 33 of FIG. 2;

FIG. 4 is an exploded perspective view of the mounting strip and hat assembly; and

FIG. 5 is an end view of the mounting strip and hanger.

PREFERRED EMBODIMENT Reference is now made to the drawing, FIGS. 1 through 5, inclusive, illustrating the presently preferred form of the invention.

The awning structure is made from a plurality of pans P which are placed in side-by-side relationship with their elevated end being supported from the wall W of the appurtenant structure. FIG. 2 shows pan Pl at one side of the awning, the adjoining pan P2, and a portion of pan P3. Each of the pans has a flat bottom wall 60, an inner side wall 61, and an outer side wall 62. The inner side wall 61 is characterized by a joining portion 61a which is bent over inwardly of the pan. The outer side wall 62 is characterized by a joining portion 62a which is bent over in a direction outwardly of the pan. Therefore, as shown in FIG. 2, the joining portion 610 of pan P2 and the joining portion 62a of pan P1 are interengaged in a secure relationship which also prevents any leakage of water between the pans P1 and P2.

The elevated end of the pans P is supported from the wall W by means of a mounting strip 10 and hat assembly HA. These parts are shown in a fragmentary exploded perspective view in FIG. 4, and also shown in a cross-sectional view in FIG. 1.

The parts of the hat assembly HA are a hanger 20, and a flashing 30. There is a mounting strip 10 which goes the full length of the awning structure, i.e., the cumulative total width of all of the pans P. In similar fash ion hanger 20 the full length of the awning structure. The flashing 30 consists of one or more sheets arranged in a longitudinal sequence, and hence in some of the views these different sheets or sections are designated as 30a, 30b, and 30c, respectively.

The mounting strip or rail includes a flat side 11 and a joining side 12. The joining side 12 is laterally curved through an angle of at least 180. The flat side 11 of the mounting strip is fastened to wall W by means of screws 15. In the particular illustration the flat side 11 is below the joining side 12, but inverse arrangement may be employed if desired. A strip of caulking material 17 is placed above the mounting strip 10 to prevent any leakage of water between strip 10 and wall W.

The hanger 20 includes "a joining portion 21, a vertical panel 22, and a horizontal panel 23. The

panels

22, 23 together constitute the pan retaining or supporting portion of the hanger. Panel 23 supports the under surface of pans P, while vertical panel 22 extends across and closes the otherwise open ends of the pans. The joining portion 21 extends from the upper edge of vertical panel 22, and is therefore located at the upper corner of the elevated ends of pans P. The outer edge of horizontal panel 23 is also provided with a downwardly depending flange 24.

In asembling the awning the mounting strip 10 is first placed in its proper position and fastened down by means of the screws 15. Caulking material 17 is preferably added at this time. Then the hanger 20 is positioned by sliding its joining portion 21 longitudinally into the joining portion 12 of mounting strip 10. See FIG. 5. It will be noted that joining portion 21 is adapted for a tight, pivoting nesting relationship with the joining side 12 of mounting strip 10. When the hanger has been inserted in the full length of .the mounting strip it is then rotated downward, as indicated by the arrow in FIG. 5.

Several pans are now attached together in side-byside relationship, and their outer ends (not shown) are placed upon a suitable supporting structure. The elevated ends of the pans are placed upon hanger 20. Screws 25 are now used to fasten the bottom walls 60 of the various pans to the horizontal panel 23 of the hanger 20. This results in securement of the pans P and also establishes the angular position of the hanger 20.

Prior to assembling additional pans into the awning structure, the next step is to commence the installation of the flashing by placement of the first flashing sheet or section. Since the flashing structure is unique it will now be described in detail.

Each flashing sheet is integrally formed from a single flat sheet of metal. It includes a rectangular body or panel 32 which is the pan covering portion of the flashing. It also includes a joining portion 31 which is laterally curved in order to nest within the joining portion 21 of hanger 20 in an interlocking relationship. The joining portion 3] of each flashing sheet is made somewhat shorter than the rectangular body or panel 32. More specifically, as shown in FIG. 4 the rectangular body 32 extends somewhat beyond the joining portion 31 on both ends thereof.

The first flashing sheet 30a is raised at an angle and its joining portion 31 is then inserted into the joining portion 21 of hanger 20. The flashing sheet is then rotated downward until it rests upon the upper surfaces of the pan ribs, specifically, the joining

portions

61a and 62a of pan Pl. It is then secured to the ribs by means of

screws

35, 36.

The rectangular body 32 of the flashing sheet together with

panels

22 and 23 of the hanger form a U- shaped structure which completely encloses the elevated end of the pans. Because of the secure interlock of joining portion 31, joining portion 21, and joining side 12, this structure is very well sealed against the entrance of water. It may, however, be desired to utilize a filler pad 50 made of foam plastic material or the like, to block off the end of each pan at a point which lies beneath the flashing. Filler pad 50 is shown in FIG. 1. When filler pad 50 is to be used it is preferably installed prior to rotating the flashing downward to its final position of rest.

After one flashing sheet has been installed, it is then convenient for the installer to place one or more additional pans in their proper positions and secure them in place. Then a second flashing sheet may be installed. The second flashing sheet 30b is inserted at an angle and is slid longitudinally of the hanger 20 until its joining portion 31 butts against the joining portion 31 of flashing sheet 30a. Then the flashing sheet 30b is rotated downward into place. This results in an overlapping relationship between the rectangular body of the second flashing sheet and the rectangular body of the first flashing sheet. Specifically, the end of flashing sheet 30b overlaps the end of flashing sheet 30a. Flashing sheet 30b is then fastened down with

screws

35, 36.

The construction of the awning is then continued in this manner until it is completed. The pans are added one, two, three, or four at a time. Then one or two flashing sheets are added. Then more pans are installed. The exact procedure depends upon the width of the pans, the length of the flashing sheets, and the arm length of the installer. The significant advantage of this procedure is that the installer need not walk on top of the awning structure in order to install the flashing. Furthermore, he need not manipulate a lengthy and bulky flashing.

The hanger need not be inserted lengthwise into the mounting strip but may be inserted from the side, then rotated down as shown in FIG. 5.

The flashing may if desired be formed as a single section, and it may be progressively rotated downward along its length and secured, as successive pans are installed.
