FOLDING AWNING I Filed July 31, 1940 2 Sheets-Sheet 2 Invenior T V/LL/A/v/ P. Mc CA/ THY fliiorney Patented Oct. 21, 1941 UNITED STATE s PATIENT; OFFICE FOLDING AWNING William P. McCarthy, Los Angeles, Calif. 7 Application July 31, 1940, Serial No. 348,785 3' Claims. (Cl. 15 6-15) This invention relates to a folding awning.

-Most awnings now used are made of fabric which may be folded or rolled to a closed position, or are made of a plurality of slats which may be simultaneously moved to various degrees of opened position with relation to each other. These structures for the most part do not afford a very great degree of permanency since the fabric readily deteriorates and the mountings for the various slats get out of order. Furthermore, when awnings of the commonly constructed types are used on fronts of stores or the like, it is evident that any signs which have been painted on the awnings will be concealed when a fabric awning is rolled up or folded, and that at various degrees .of opening of the slat awning the signs would be rendered illegible. It is the principal object of the present invention to provide an awning or shelter structure of a permanent character which is so constructed as to. be readily moved to or from its sheltering and non-sheltering positions, the awning being so constructed as to display any signs carried upon it whether the awning is positioned in its folded or outstretched position, .the awning structure being simple in its, construction and easily installed.

The present invention contemplates the provision of an awning structure having a pair of substantially rigid panels which are articulately connected together and one of which is mounted on a wall or other supporting structure in a man-.

outermost panel retained in a non-concealed position, whereby the folded awning will be sightly and any'signs or designs thereon may be displayed at all times.

v The invention is illustrated by way of example in the accompanying drawings, in which:

Figure 1 is a view in perspective showing an awning of the type disclosed in its outstretched or unfolded position.

Fig. 2 is a view in vertical section and elevation showing the awning in its outstretched position in solid lines and in its folded positionin dotted lines. I

Fig. 3 is an enlarged View in fragmentary section as seen on the line 33 of Fig. 2, and indicates the means by which the awning is mounted operating structure is of slightly. different construction.

Fig. 5 is a view in section and elevation showing another form'of the invention.

Fig. 6 is an enlarged fragmentary view showing a detail of construction'of the hinge'of the two panels of the awning.

Referring more particularly to the drawings, l0 indicates a permanent support, such for ex-' ample as a wall. A window or door opening ll may be formed through this wall, the opening Mounted above' covered with fabric. As shown in the drawings,

the two panels are of substantially the same size and are rectangular in shape. It will be understood that the dimensions may be varied as desired. The panels are provided with transversely extending structural supporting elements [6 and [1 to which the panels are secured by some such suitable fastening means as rivets I8. The supporting members l6 and I! may be of any desired sectional configuration, although it has been found that structural members of T-shape are satisfactory. Referring to Fig. 3 of the drawings, it will be seen that the vertical leg I9 of the T-section is cut away at its upper end on each of the structural elements I6 so that the transverse web 20 may project beyond the leg 16 and terminate in a hook element 2|. ment extends through a slotted opening 22 in the horizontal leg of an angle bracket 23. The

angle bracket may extend the entire width of the awning, as shown in Fig. lof the drawings.

The vertical leg of the bracket is secured by screws'24 or other suitable means to the fixed support l0. By this arrangement it will be evident that the panel l5 of the awning will be' articulately connected to the'bracket structure 23. so that it may swing upwardly from the solid line positions inFigs. 2 and 3 to the dotted line positions.

Disposed at opposite ends of the angle bracket 23 and carried thereby are bearing structures 25.

These bearingstructures support the trunnions 26 of a horizontally extending shaft or roller 2'! around which operating cables 28 may be wound.

In one of the bearing structures 25 worm gears- ;29 and 30 are housed. It will be understood that It will be understood also that if desired panels may be made with a rigid frame This hook ole-- other types of gears might be used, although the irreversible characteristic of a worm gear makes it desirable, since other holding means are not required to set the awning in any selected position. The gear 29 is mounted upon one of the trunnions 2B of the roller 21. The gear 30 which is in mesh therewith is mounted upon a vertical operating shaft 3| which extends downwardly through a bearing in a gear box 32 supported in convenient reach for operation. Suitable gears 33 and 34 are mounted within the bearing box, the gear 33 being carried upon the shaft 3 I. The

gear 34 which is in mesh therewith may be engaged by a crank arm 35 by which it can be rotated. As shown in Fig. 1 of the drawings, this crank arm may be applied from the exterior of the building. Other views of the drawings 4 indicate the crank arm as extending through the wall so that the awning may be manipulated from the inner dwelling.

The outer free end of the panel I5 is pivotally connected to the panel I4. This connection is particularly shown in Fig. 6 of the drawings, where it will be seen that the frame elements l6 of the panel I5 are connected to the frame elements I? of the panel I4 by pivot pins 35. The upper transverse portion of. the frame elements I! adjacent to the pivots are bent upwardly, as indicated at 31, to provide an abutting stop for the two panels and to thusdetermine their angular relation to each other. Secured to the frame members I! by pivot pins 38 are brace arms 39. These brace arms are pivoted on pins 40 carried by brackets 4| secured. to the fixed support I;

They act to hold the lower free end of the panel M in its outermost position when the awning is outstretched and to guide the panel I4 as it folds with the panel I to the dotted line position shown in Fig.2.

In the form of the invention shown in Fig. 4 of the drawings the upper panel I5 of the awning is rigidly secured to a roller 42, which takes the place of the roller '21 previously described, and is rotated by the shaft 3| through the gearing described as being associated with that shaft. Thus, the panel I5 swings bodily as the roller 42 rotates on its axis. In the form of the invention shown in Fig. 5 the awning i3 is shown with its panels I4 and i5 disposed in a common plane when in its unfolded and outstretched position. This makes it necessary for means to be provided to spring the joint at the pivot 35. This is accomplished by the use of an extension arm 43 over which'the cable 28 rides. By this arrangementthe folding of. the panels I4 and I5 with relation to each other may be initiated when the cables 28 are drawn, after which subsequent winding of the cables 23 on the roller 21 will cause the elements to continue their folding operation.

' In operation of the present invention the preferred form of. the structure is assembled as shown in Figs. 1, 2 and 3 of the drawings. It will be seen that the angle bracket 23 is secured horizontally over a wall opening, and that the brackets 25for the roller 21 and the gear box 34 are properly positioned. When the awning is to be lowered the cable 28 is paid out from the roller 21 so that the awning structure will move from the. dotted line position in Fig. 2 to the solid line position. The downward movement of the panels will be brought about by gravity, while the un-' winding of the cable 28 is brought about by drives the shaft 3|. As the awning structure H to the wall Ill.

swings downwardly it is caused to swing outwardly due to the action of the guide and brace arms 39 which force the lower ends of the panels M in an outward spaced position with relation to the fixed support I0. When it is intended to elevate the awning the shaft 31 is rotated through the operating crank 35. This will cause the cable 28 to be wound onto the roller 21 and to lift the entire structure. The panel I5 will hinge on its hinge elements 2| as it is forced to an upper position, and the panel I4 will be elevated to fold against the panel I5 and lie substantially parallel When this folded position has been reached interruption of the rotation of the shaft 3| will permit the awning elements to remain in their folded positions since the worm gears 29' and 30 will lock and prevent rotation 1 of the roller 21. Attention is directed to the fact that in this folding operation the panel I4 will remain outermost and that any sign or design on it will be at all times presented to view.

. In the form of the invention shown in Fig. 4 manipulation of the shaft 3| will cause rotation of the member 42 with a corresponding swinging movement of "the panel I5 to its lower position shown in solid lines in Fig. 4 and to its upper position as indicated in dotted lines in that figure.

The operation of the structure shown in Fig. 5 is obvious.

It will thus be seen from an examination of the drawings and from the foregoing specification that the'awning structure .here disclosed is simple in its design, rigid and rugged in structure, and that it provides means whereby an awning may be quickly and conveniently moved from a closed to an open position and vice versa.

While I have shown the preferred form of my invention as now known to me, it will be understood that various changes may be made in combination, construction and arrangement of parts by those skilled in the art, without departing from the spirit of my invention as claimed.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:
