14 Claims. (Cl. 156-15) This invention relates to a ventilated awning, and particularly to one which is fabricated chiefly of sheet metal.

' An object of the invention is to provide a sheet metal awning of the ventilated type, embodying simple, effective and durable means for ventilating the sloping front of the awning, and also the triangular sides thereof.

Another object of the invention is to provide an awning of the character stated, embodying an improved arrangement of shutters for selectively ventilating and closing the sloping front of the awning, which shutters may be applied to the framework of the structure after the framework has been mounted upon the side of a building and about a window or other aperture.

A further object is to provide an awning of the character referred to, which may be shipped in knocked-down condition and mounted upon the building in sections so that the entire weight of the awning need not be lifted as a whole, in placing the awning.

Another object of the invention is to provide an improved shutter actuating means for a ventilated awning.

A further object is to provide bearing means for the individual shutters of the awnings, whereby is greatly facilitated the assembly of the awning after the main body portion thereof. has been mounted this being accomplished without the aid of a scaffold or ladder, and making possible the mounting and assembly of the awning I over which the awning is to The foregoing and other objects are attained by the means described herein and disclosed in the accompanying'drawings, in which:

against a complementary flange I5 along the lower edge of the side panel. As shown in Figs. 1 and 4, the valance may be scalloped or otherwise artistically shaped or cut, for decorative purposes. Along the rear vertical edge of each side panel l2, there maybe provided a flange turned at right-angles, as indicated by the character l6, and adapted to carry screws, bolts or other fastening devices II for mounting the side.-

- panel to the frame of a window or other aper-,-

louver has-associated therewith an opening I9,

Fig. 3, which serves as a ventilator, but which is protected against entry of rain'or the like by v the overhanging louver I8.

Along the forward sloping edge of each side panel I2, there may be provided an inwardly directed flange running substantially the full length of said edge, and serving as a shelf or support for the shutter mounting means. Each flange may consist of an inwardly turned leg 20, (Fig. 7). an outwardly turned leg 22, and an upstanding leg 2|, all of these being integral parts of the side panel l2. The legs 22 of the angle members are adapted to support the spaced parallel bars or beams 23 and 24, which may rest against the side legs 2| as illustrated in Fig. 7. As will readily be understood, the upstanding legs 2! may be omitted, if desired, however, these I members perform as trimming strips and also as reinforcing elements when included in the combination. The bars or beams 23' and 24 preferably extend the full length of the sloping front of the awning structure, and they may be securely fastened to the flanges 20 and 22 by means of screws or bolts 25, which may pass through the flanges and into threaded bores 26 provided in the material of the bars or beams. A limited number of bolts or screws 25 is indicated in the drawings, but itwill be understood that the number of them maybe increased when necessary, to furnish a substantially rigid structure. The nature and function of the bars or beams 23 and 24 will be explained more fully hereinafter.

The several characters 21, indicate sheet metal shutters or movable panels which are mounted on axles or journals 28-29 so that all of the shut-' shutter 21 is provided along one of its longitudinal edges with a cylindrical bead 30 that not only reinforces the shutter lengthwise, but also furnishes sockets for the reception and support of the short axles or stud shafts 28-29 (Fig. 7). Along the opposite longitudinal edge of each shutter, there is formed an open channel or hood ters may be disposed substantially at right angles to the plane of the sloping front of the awning structure.

To the under faces of the shutters, and substantially at locations midway between the ends of the shutters, suitable links or arms 44 are fastened securely by welding, r veting, or the like, these elements 44 forming part of the actuating mechanism for the shutters. As shown herein, each link may be in the form of a parallelogram formed from sheet metal, and having along one of its edges a right angled flange 45 that abuts the under" face of the shutter so that the elements 44 of all the shutters rest in a common plane which is normal or perpendicular to the under faces of all the shutters. As previously stated. all of the elements 44 preferably are located midway between the ends of the shutters. It may be noted also that they are preferably, though not necessarily, fastened close to the pivotal mountings of the shutters, and that every shutter. which is adapted to move will carry one of the link members 44.

At one corner of each link member or plate 44, there is provided a pivot 45 whereby each may be pivotally connected to a reciprocable' connecting 3|, which may be of an inverted V or U-shaped configuration, this channel or hood in each instance being adapted to cover the bead of the next adjacent shutter when the shutter is in the closed position indicated by Fig. 4. It will accordingly be understood that the open channels or hoods 3| of the various shutters furnish substantially tight joints at the sloping front of the awning structure, precluding leakage or entry of water and other foreign materials into the 'enclosure formed by the awning.

At the lower end of the sloping front, there may be furnished a fixed transverse panel 32 having an intumed flange 33 adapted to be bolted or otherwise fixed as at 34, to the transverse horizontal flange 35 of the front valance member. This fixed panel may include an upstanding transverse bead or rib '35 adapted to be engaged by the open channel or hood 3| of the lowermost shutter 21. It is preferred also that'the sloping front of the awning be furnished, at a location substantially midway between its upper and lower ends, with a second stationary panel 31, the upper longitudinal edge of which may be turned outwardly to form a rib indicated at 38 to be engaged by the movable shutter next above it. A stationary open channel or hood 39 may be furnished lengthwise of the lower edge of stationary panel 31, to cover and seal the pivotal mounting of the shutter 21 next below it.

As shown in Figs. 1 and 2, a third stationary 1 panel 49 may be provided for spanning the side panels l2, this part 40 having formed integrally therewith an upstanding vertical flange 4| suitably apertured for the reception of screws or bolts '42 which serve to attach the flange to the window frame or to the wall of the building immediately above the window. The lower longitudinal edge of stationary panel 40 preferably carries an open channel or hood 43 similar to those indicated at 3| and 29, for covering and sealing the head of the next adjacent shutter against entry of, water, dust and other foreign matter. In the preferred construction, all'of the shutters and the stationary panels 32-31-49 will rest substantially in a common plane when the shutters are in the closed position. When the shutters are opened as indicated by the broken lines 219 of Fig. 4, the planes of the shutrod or bar 41. In the preferred construction the connecting rod or bar 41 is a longitudinal sheet of metal bent along its longitudinal axis in order that it will be substantially U-shaped in cross section, the legs of the U serving. to embrace the plate-like elements 44. Asv will be understood, the pivots 45, which may be in the form of rivets or small bolts, or perhaps clevis pins with cotter pins at their ends, extend through the spaced parallel'legs of the U-shaped connecting member -41, and also through the several plate links 44 embraced therebetween. This furnishes a neat and substantial actuating connecting structure,

whereby reciprocating movement of the part 41 will result in opening and closing all of the shutters, depending upon the direction of reciprocation.

The means for reciprocating the connecting bar or member 41 may consist ofa rock shaft 4b, (Fig. 2), having a lever 49 fixed thereto, said lever having a free end furnished with a pivot 01' stud 50 adapted to work within a slot 5| of an extension of the bar 41. While it is possible to form the slot directly in the material of bar 41,- better practice may be to fix a separate .bracket 52 upon the bar end for carrying the slot 5|;

however, it is considered immaterial whether the pivbtn'50 be associated with the bar 41 one way or the other. The only requirement is that there be a pivotal connection between bar 41 and lever 49.

face of part 40.

At a location near one of the side panels l2, the rock shaft 48 carries a second fixed lever 54,, the outer end of which carriesa pivot 55 that connects it with'a swing bar 56. This swing bar 56, in the normally closed condition of the shutters, stands approximately vertical, and it has its lower end pivoted as: at 51 to a slide 58. The

slide is adapted to bemoved horizontally along a guide 59, which guide may be in the form of a rod, shaft, or bar having its opposite ends anchored securely in any suitable manner. For example, if the guide be made of tubular stock, its rear end may be flattened as at GIL and perforated to receive lag screws, bolts or the like 8i (Fig. for fixing that end of the rod to the window frame or other .part of a building, or to the flange l6 of a side panel l2. The opposite end of the rod may be bifurcated as at, 52 (Figs. 4 and 6) and fitted onto an edge of a gusset plate 63 or the like, and pinned or bolted thereto at N. The

plate 63 may be formed triangular to fit within a forward comer of the awning structure, where it 'may be bolted to flanges 33 and 35, or otherwise secured.

The slide 50 may include a handle portion 65 to be gripped and shifted by a person desiring to upward force, movement of the slide byany forces i initiated at the shutters is impossible. In other wordsjfthe slide structure maybe considered irreversible in the sense that force properly appliedto the slide for shifting it along the rod 59, will actuate the shutters, whereas force applied to unwieldy for one work-man to handle; It should be noted, in this connection, that the side panels I: may readily be mounted upon a building by means or the screws or bolts l1, independently of the shutter structure. Once the sides are fixed in place, without the shutters, it is a simple matter to attach the shutters and their actuating mechanism, due to the means to be presently de-' scribed. In this connection, the reader is referred to Figs. '7 and 8 of the drawings.

As will be understood, the side panels I! carv rying the bars or beams 23 and 24, will be in substantial spaced parallelism when mounted upon the building. The bars or beams 23 and 24 are to be bored transversely, at the factory, for re- T ception of the stud shafts or axles 28 and is of the shutters. The stud or axle 28 preferably is fixedly supported inthe end of bead 30, whereas the other stud or axle 28' is loose in its bead section.

" The first step in mounting one of the shutters 'blade or a pick in the small crack of the bead,

the shutters in the attempt toshift the slide will hanced by the fact that the leverage ratio be- ,comes greateras the slide approaches the front of the awning, at which time the links or plates 44 approach the limit of their tuming'movement and the force necessary to advance them further by means of bar 41 increases. It should be noted indicated at 89 of Fig. 8, for contacting the loose stud 28 and shifting it longitudinally outwardly and into the bore 68. Thereafter, itis necessary only to punch in atab 69, provided inthe head 30, until the tab extends into'the bead sufiiciently to block retractile movement of the stud. This completes the'work of mounting a shutter, and it should be noted that all this can be accomplished by a workman reaching through the window covered by the awning. All of the shutters are to also that a straight downward pull upon member 56 would be effective to rotate the rock shaft 48 a lesser amount, than is the case where the member 56 is swung forwardly at its lower end during the shutter-opening movement, as specifled herein. Therefore, it should be evident that the actuating mechanism of the invention is so constructed as to have a great range of movement foropening the shutters wide, while at the same time a leverage ratio is provided for in the interest of effortless manipulation. Finally, the structure of the actuating means is seen to be extremely simple and trouble-free.

Although the slide 58 may be made as a casting or otherwise, it is possible to form it merely from 'a properly shaped sheet metal blank turned upon itself at the handle to provide the handle, the slide portion, and the ears for supporting the pivot 51. 'Should it be considered desirable to provide for a positive fixation of the slide upon the bar or rod 59, a bolt and thumb nut may be furnished as indicated at. to preclude unintentional or unauthorized adjusting of the awning shutters against the wishes of the owner or person in charge thereof.

Earlier herein was mentioned the ease with which the awning structure may be shipped in knock-down condition, and mounted upon a building in sections which are nottoo heavy or he applied as above explained, and of course the.

. the shutters, making accessibility easy.

From the foregoing, it should be evident that the improvements herein set forth.result in the,

provision of a simple anddurable workable structure which may be installed with a minimum of time and effort, and without resort to ladders or scaffolds which are expensive and troublesome to erect at the higher windows of a building. La-

bor costs in applying the awnings are materially reduced, and awnings of the kind herein disclosed present no appreciable problems of maintenance and repair. They are fire-proof and hurricaneproof, will not readily take on a soiled or worn appearance, and they afford complete control, of rain, wind, and sunshine directed at a window or other opening of a building. Moreover, the use of awnings constructed in accordance with the present invention results in the elimination of noises and squeaks which are inherent in other types of awnings when subjected to high winds, and they are practically indestructible. Other and further advantages will be evident to persons (familiar with the subject.

Whereas for the sake of convenience and simplification of disclosure, the actuating mechanism for the shutters is shown applied to the far side of the awning structure, it is evident that greater convenience may result if it be applied to the In conclusion, it is to be understood that var- I As indicated by Figs. 7 and ions modifications and changes in the structural details of the device may be made, within the scope of. the appended claims, without departing.
