This invention relates 'to a slat type awning forum on 'the outside of windows.

a slat mounting means wherein the slats are rigidly held in their proper positions but are permitted to expand and contract with changes in temperature. A

In addition, it is an object of my invention to provide a slat mounting wherein the slats are formed of a somewhat resilient material and are held in position under tension to prevent wind vibration and rattling.

Another object of .my inventionis to provide an awning mounting clip having .means to frictionally grasp the .rear end of one awning slat and means to .hold the forward end of the next succeedingslat.

Yet another object of my invention is to provide an awning slat mounting clip formed of resilient material and having means to grasp .anawning slat, said means being adaptedlto yield in response to expansion and contraction of the awningslat.

A further object of my invention is to provide an awning slat mounting clip having means to hold the front end of a slat under tension and spaced from the back of the next succeeding slat.

Also, it is an object of my invention to provide an awning slat mounting clip formed by punching out a portion of the awning side frame bars, bending this portion to form an upright clip member adapted to be connected with the front end of a slat, and punching out a section of said clip portion to form a means to grasp the rear end of the next succeeding slat.

Other objects and advantages of this invention will become apparent from the following description.

Figure 8 is a sectional view taken on 8-8 of Figure -6. Figure 9 -is a top view of the support-bar of.F-i'gure 6. As seen in Figure 1, a slat type awning,generally-designated as 1, is shown inposition to be mounted upon :a wall. The awning is formed with a pair of frame bars 2,

one of which is hidden from view in Figure 1, and a top mounting slat 3. The top mountingslat-may'bepivotally connected to the frame bars or may be connected by any other convenient means. As thetop mounting slat forms no part of this invention, the connecting means therefor is not described in detail.

The top mounting slat is formed with a'flange 4 having perforations '5; This flange is adapted to be .abutted against a wall and screws may be inserted through the perforations for fastening to the wall.

A plurality of slats are secured to the frame :bars to form the completed awning. The slats comprise abo'dy portion 6 bent into a curved shape and having a forward "flange 7. Atthe rear of the slats, and integral with the body portion -6 is a channel 8 having a base 9,, adapted to contact the frame bars, and terminating in a flange 10.

The slats, themselves,-'are formed -of a somewhat resil- 'ient metallicmaterial, such as aluminum.

Mounting clips 11 are provided to fasten the slats to the frame bars 2. As shown in Figure 5, the clip rc'omprises an upstanding leg 12 whose 'endis'bent into a flange -13. Integral with the lower part of said leg is a doubled portion forming-a base 14. The doubled ,portion'or base 14 is extended to form a second leg .15whi'ch-termin'ates in asecond flange 16.

.An opening-17 is located in the base 14, and through :this opening a screw or bolt 18 may be :inserted to rigidly mount the clip upon the awning frame bar.

The clip 10 maybe made from sheet metal having :revsil ient properties, or any other similar suitable material.

The flange 1301? the mounting clip 12 is fastened to the flange 7-of the awning slats. This fastening :may be accomplished by means-of a screw or rivet 20 as .shown in Figure .2. In Figure 4, the clip flange 113 adapted to frictionally grasp a V-shaped channel 21 which is secured to the slat by means of a screw 22 or the like.

Figure 3 illustrates means of fastening the clip, namely by bending slat flange 7 back a suflicient distance to be frictionally engaged and grasped by the clip flange 13. This bending may be accomplished in the local area of the clip or the entire flange 7 may be so bent.

The rear end of each awning slat is retained in position by means of the clip second flange 15 grasping the rear slat flange 10 as is illustrated in Figures 2 and 3.

Referring next, to the modification shown in Figures 6 to 9 inclusive. In this structure, the awning frame side bars 25 are formed as an inverted U-shaped channel. The web 26, of the channel is die punched to form a clip portion 27 which is upwardly bent at bend line 28.

The upper end of said clip portion is bent to form a' slat engaging flange 29. This flange nestles closely to the awning slat flange 7 and the two are connected together by means of a punched indentation 30, as seen in Figures 6 and 8, or by wrapping flange 29 around the end of awning flange 7, as seen at 30A in Figure 6. Any other suitable means may be used, as for example, those illustrated in Figures 2, 3 and 4.

The lower part of the clip portion 27, is also punched out to form a grasping finger or grasping flange 31. As can be seen in Figure 7, this finger is double bent so as to be spaced a distance from the main clip portion. It is within this space that slat flange 10 is inserted to be frictionally retained in position between the finger 31 and the main clip portion 27.

As in the case of clip 11, the integral clip of Figures 6 relative to the clips. appearing, sturdy awning, which is not subject to warpage to 9, will be somewhat resilient due to the sheet material or distortion due to temperature changes or other weather conditions.

This invention may be developed within the scope of the following claims without departing from the essential features of said invention and it is desired that the specification and drawings be read as being merely illustrative of a practical embodiment of the same and not in a .strictly limiting sense.
