3 Claims. (Cl. 160-58) This invention relates to awnings, and more particularly to fabric awnings having edges that fit closely against the window casing.

Conventional fabric awnings are usually formed of heavy canvas treated with fireproofing material which adds to the stiffness of the canvas. Such awnings also are usually arranged whereby the edges adjacent the Window casing fit closely thereagainst with the result that air is normally trapped in the upper portion of the awning and sun shining on the awning causes the trapped air to increase in temperature. Also, strong currents of air or winds tend to raise the awning and then when the wind is reduced in velocity the awnings drop down, providing a severe jar on the canvas parts, and in many instances, damaging the hardware. The stiffness of the canvas makes it difficult to raise same as the canvas resists folding thereby increasing the wear on the canvas, ropes and hardware for the awning.

The principal objects of the present invention are to provide an awning with ventilating openings which allow strong currents of air to find egress from under the awning; to provide such an awning wherein the ventilating openings allow additional light to enter thereunder whereby the rooms having the windows covered by the awnings are lighter; to provide such an awning wherein the ventilating opening is positioned to facilitate the folding of the canvas when the awning is raised thereby reducing the effort for raising and lowering operations and giving longer life to the ropes and hardware fitting for the awnings; to provide an awning structure with a ventilating opening structure that is reinforced at the opening to aid in holding the fabric outstretched and to prevent tearing or damage to the awning; and to provide a ventilated awning structure that is economical to manufacture and affording passage of light and air under the awning and increased life to the awning and mountings thereof.

In accomplishing these and other objects of the present invention, 1 have provided improved details of structure, the preferred form of which is illustrated in the accom panying drawings, wherein:

Fig. 1 is a perspective view of an awning embodying the present invention positioned over a window casing.

Fig. 2 is a vertical sectional view through the awning taken on the line 22, Fig. 1.

Fig. 3 is a vertical section through the awning taken on the line 3-3, Fig. 1.

Fig. 4 is a perspective view of the awning in partially raised folded position.

Referring more in detail to the drawings:

1 designates a canvas awning having a top or front wall 2, and side walls or members 3 of substantially triangular form. The top or front wall 2 slopes downwardly and outwardly from the upper edge 4 thereof which is suitably secured to a window casing 5 in any conventional manner. In the illustrated structure, the upper portion of the top or front wall 2 is folded back under said top wall and sewed by a line of stitching 6 forming a loop 7 through which extends the head rod 8 secured to the window casing 5 by suitable fastening devices as in conventional structures.

Depending from the lower end of the front wall 2 are valances 9, and behind the valance at the lower end of the inclined front wall 2 is a strip of fabric 10 sewed by lines of stitching 11 and 12 to said front wall and valance to form the usual horizontal pocket 13- in which is mounted a rod 14 of a frame 15 that is substantially U-shaped. The frame 15 has legs 16 extending from the ends of the bar 14 under and engaging the side panels or members 3 and preferably through horizontal pockets 13 thereon. The legs 16 terminate in fittings 17 pivotally mounted as at 18 on suitable brackets 19 secured to the window casing 5. I

The side panels preferably have lower edges 20 substantially on a level with the lower edges of the valances 9 when the awning is in lowered position. The vertical edges 21 of said side panels preferably substantially engage the face of the window casing 5 whereby the top and sides of the awning fit closely against said window casing. The side panels 3 preferably have their upper edges turned outwardly to form flanges 22 engaging the underside of the top or front panel 2, with the side marginal portions 23 of the top wall turned under to underlie the flange 22 and sewed thereto by lines of stitching 24 forming a triple thickness of the fabric or canvas at triangular in shape with edge portions 26 turned. inwardly in underlapping relation and sewed to the side panels 3 by lines of stitching 27 to form hem-like edges for the openings 25 and provide at least a double thickness of fabric or canvas around said opening 25. The upper edge 28 and vertical or rear edge 29 of the opening 25 are spaced from the edges of the side panels as illustrated in Fig. 3. With this arrangement, when the awning is in lowered position, the awning protects the associated window from the hot rays of the sun but at the same time enables additional light to enter under the awning affording more light into the room behind the window. The openings 25 also enable air to pass through and circulate under the awning, permitting passage of heated air from under the awning and thereby reducing the temperature of the air under the awning. The openings also permit egress of currents of air from under the awning eliminating tendency of strong currents to lift the awning and resulting shocks to the awning and hardware that will result from winds or strong air currents.

As in conventional practice, the awning has ropes 30 secured to the bar 14 and extending upwardly through suitable members 31 adjacent the head rod 8 and then downwardly along the side where the end of the rope is adapted to be connected to a fastening member 32. When it is desired to raise the awning, the rope is disengaged from the fastening member 32 and pulled, swinging the frame 15 upwardly as illustrated in Fig. 4. The openings 25 reduce the stiffness at the upper portion of the awning whereby the side panels are easily folded and the top wall folds, reducing the pull on the rope that is necessary to raise the awning. This also tends to reduce the tendency of the awning walls to buckle at the connections of the front and side walls and the stress resulting therefrom during the raising operation, thereby providing longer life for the fabric of the awning.

It is to be understood that while I have illustrated and described one form of my invention, it is not to be limited to the specific form or arrangement of parts herein described and shown except insofar as such limitations are included in the claims.

What I claim and desire to secure by Letters Patent is;
