Application September 25, 1941, Serial No. 412,233

5 Claims.

This invention relates'to awnings and hasfor its object the provision of an awningwhich will not only provide shade but will also serve to deflect wind into the opening to be shaded and thus provide a measure of ventilation for the building on which the awning may be used.

Further objects will appear in the following description.

In the drawing:

Figure 1 is a perspective view of my improved awning shown as applied to a window; and

Figure 2 is a side elevation.

Referring to the drawing, the awning comprises a top fabric shade member 3, the upper edge of which is turned over and sewed down to provide a hem into which a rod 5 may be inserted. The rod is secured to the window frame or wall of the building by any desired means, such as hooks 6. In the claims I refer to securing parts of the awning to a building, but it will be understood that I include within this term any part of the building, such as the walls, window frames, windows, etc.

Near the lower end of the top member 3 there is provided a strip of fabric 'l sewed along each edge of the strip, thus providing a hem into which the frame 8 may be inserted. This frame 8 consists of a rod which is bent to provide two arm members extending from the lower end of the shade member to the window frame 9. The ends of the arms are secured to the window frame by means of a bracket l which permits the arms to swing so that the frame may be raised and lowered by hoisting ropes (not shown) in the usual manner.

To the lower surface of the shade member 3, and preferably centrally thereof, the triangular jib member H is attached. This jib is a flat, generally triangular fabric sheet and is attached to the shade member 3 by sewing it thereto as indicated at [2. The lower corner l3 of the jib is provided with a loop M which may be slipped over a hook i which is secured to the window frame. I prefer to have the hook l5 so located that the distance from the hook to the top of the shade member 3 is somewhat less than the length of the inner edge 16 of the jib so that instead of being drawn taut, the inner part of the jib will be free to belly out in the wind.

When the awning is lowered and the lower end of the jib secured, the top member 3 provides a shade for the window. The jib II will also provide a certain amount of shade but the most important function of the jib is to deflect the wind toward the window.

This it does very effectively, -no matter from what direction the windis blowing, but the jib is especially useful when the wind is blowing in such direction that it-would not normally flow Insuch case, however, with myimproved awning the jib will belly out somewhat in the form of-a scoop and deflect the wind in sucha way thatit will enter the open window.

A further advantage of my impoved awning is that it does not have the side walls usually found in awnings. In awnings with such side walls the air is trapped beneath the awning and becomes heated, and any of the air thus trapped which enters the window will, of course, tend to heat up the room which it enters, thus to a certain extent defeating the very purpose of shading the window.

In the claims, for convenience I have referred to the awning as a window awning, but it will be understood that it can be used effectively in most places where awnings would be applied.

It will be understood, of course, that the lower corner of the jib ll does not have to extend below the lower end of the top shade member 3, and if desired the lower edge of the jib may be in a horizontal plane or otherwise. In such case it would probably be necessary to provide a hook on the window itself to which the loop I l could be secured, or some other arrangement for securing the lower corner of the jib, but in any event such arrangement would still provide means for deflecting the wind into the open window.

I claim:

1. A combined window awning and ventilating device comprising a substantially rectangular top shading member with means at the upper edge thereof whereby it may be secured to a building and means to hold the lower end out from the window the said shading member sloping outwardly and downwardly from the building, a triangular jib member attached along one edge to the central part of the lower surface of the top member, and means at the lower corner of the jib whereby it may be secured to a building, the said jib when secured extending at an angle to the top member and being adapted to defiec wind into the open window. I

2. A combined window awning and ventilating device comprising a substantially rectangular top shading member with means at the upper edge thereof whereby it may be secured to a building and means to hold the lower end out from the window the said shading member sloping outwardly and downwardly from the buildin a triangular jib member attached along one edge to the central part of the lower surface of the top member, and means to secure the lower corner of the jib to the building, the jib and the edges thereof being sufliciently resilient that the part of the jib adjacent the window may belly in the wind to one side or the other and thus deflect wind toward the window.

3. A combined window awning and ventilating device comprising a substantially rectangular top shading member with means at the upper edge thereof whereby it may be secured to a building and means to hold the lower end out from the window the said shading member sloping outwardly and downwardly from the building, a triangular jib member attached along one edge to the central part of the lower surface of the top member, the lower corner of the jib extending below the lower end of the top member and means whereby the lower corner of the jib may be secured to a building, the said jib when secured extending at an angle to the top member and being adapted to deflect wind into the open window.

4. A combined window awning and ventilating device comprising a substantially rectangular flat fabric top shading member with means at the upper edge thereof whereby it may be secured to a building and means to hold the lower end out from the window the said shading member sloping outwardly and downwardly from the building, a triangular fabric jib member attached along one edge to the central part of the lower surface of the top member and means at the lower corner of the jib whereby it may be secured to a building, the said jib when secured extending at an angle to the top member and having the inner edge thereof sufliciently loose to belly in the wind to deflect wind into the open window.

5. A combined window awning and ventilating device comprising a substantially rectangular top shading member having means at the upper edge thereof whereby it may be secured to a building, a frame member pivotally secured to the building at one end and having the other end attached to the lower end of saidshade member
