3 Claims.

This invention relates to what is generally termed awning shutters and particularly to devices of that kind which are pivotally supported at the-u-pper end thereof on a building or other structure and arranged to swing into position to cover an opening in the building, such as a window, the end of a porch, or the like, and which can be swung outwardly from the building and held in a desired position to afford access of light and air to the building.

It is the purpose of the present invention to provide an awning shutter of this kind which can be easily and quickly and smoothly manipulated to open or close the same, which will be automatically locked in open position when swung outwardly from the window or other opening, and which is constructed in such a way as to conceal much of the operating mechanism so that such mechanism will not detract from the appearance of the shutter and will be protected from the weather or injury.

Another object of the invention is to provide simple and eflicient means for opening and closing the ventilating louvers with which such shutters are usually provided.

Other advantages of the invention will be apparent from the accompanying drawings, illustrating one embodiment thereof, and the accompanying specification describing the same and forming part hereof.

In said drawings,

Figure 3 is a horizontal section on the line 33 of Figure 1;

Figure 4 is a vertical section of a shutter, such as shown in Figure -1, with the lower end thereof swung outwardly from the window or building;

Figure 5 is an enlarged detailed section illustrating the manner of pivotally supporting the upper end of the shutter;

Figure 8 is a transverse section on the line 8-8 of Figure 6; and

Figure 9 is afragmentary perspective view of a slightly modified form of device.

Referring to the drawings in detail, the invention is shown applied to a building generally IDA rigidly connected by an upper transverse member IDB and a lower transverse member IDC. The upper transverse member IDB is pivotally supported on a supporting plate P which is rigidly secured to the building above the window or other opening to be protected.

i The longitudinal side members IDA and transverse members IDB and IDC form a rigid open framework in which a louver construction may be mounted, as later described. It is to be understood that instead of the louvers, the shutter may be formed of one or more fiat sheets of metal rigidly secured to the side members IDA.

As already indicated, one feature of the present invention relates to the mechanism for operating the shutter and automatically locking the same in open position. Tothat end, the side members IDA are made in the form of hollow bars or channels, each having a slot extending longitudinally along the rear or inner side thereof. These hollow 'bars or channels may be constructed in any desired manner. Preferably they are formed from plates II bent ,into U-shape, as shown par- V ticularly in Figures 3 and 8. A plate I2 is secured to one side of the U-shaped plate I I, and a similar plate I3 is secured to the other side thereof. These plates I2 and I3 extend toward each other and the edges thereof are flanged, such flanges being spaced apart to form a slot between them, indicated at S. The plates II, II, and I3 together form the longitudinal side members IDA of the shutter and the slot S between said plates II and I2 extends longitudinally throughout the length of saidmembers.

In the arrangement shown, aplate I4 is secured to the outer face of each member IDA and extends longitudinally thereof. These plates I4 serve to pivotally support the ends of the slats or louvers, hereinafter described.

Arranged within each of the side members or channels IDA is a slide I5 shown in enlarged form in Figure 7. The side members IDA form guideways or trackways for such slides and the guideways extend longitudinally of the shutter. The slides I5 may be formed in any suitable way, but as shown, they are-made up of two angularly bent plates I5A arranged side by side but spaced apart with one flange of each resting against the inner surface of the plate II and the other flanges thereof extending outwardly through the slot S in the side bars IOA. Secured between the upper ends of the outwardly projecting flanges of the plates I5A is a latch I6 and the outer end of a brace or thrust bar I1 is also pivotally secured between said plates I5A below said latch, it being understood that a similar thrust bar is preferably provided on each side of the shutter. The thrust bars I! are curved adjacent their outer ends as shown at HA and these bars slide in the slots S of the side members IIiA as the shutter is opened or closed. The inner ends of thrust bars II are pivotally secured to the building as indicated at "B.

A coiled spring I8 is arranged within the members I A on either side of the slide I5, and each of these springs is secured at its lower end to the lower end of the slide I and at its upper end near the upper'end of the side members IOA. The springs I8 are made comparatively strong and are under tension at all times. These springs serve to draw the slides I5 upwardly within the side bars IDA and thus cause the shutter to be swung outwardly by the thrust members II.

A locking lug I8 is secured in each of the side members IDA and these lugs are so positioned that when the slides I5 are drawn upwardly, the latches I5 will automatically engage over these lugs. The latches I6 are provided on their upper ends with an inclined surface ISA which will slide over the lugs I8 and thus permit the angular portion IGB on the latches to engage said lugs I8. It will be understood that as the slides I5 are drawn upwardlyand the latches I6 engage the lugs I8, the latches I5 will yield or move outwardly to a slight extent to permit the inclined surfaces thereof to pass over the lugs I8 and engage the angular surfaces IGB. When the latches I6 are thus engaged with the lugs I9, the shutter will be firmly held in open position so that the outer end thereof cannot be moved downwardly.

Secured to each slide, preferably to the latch I8, is a suitable flexible operating member which may be in the form of a cable or chain, preferably the latter. Each of the chains 20 extends from the latch I5 through a guide 2I mounted on the thrust bar I1 and then through a guide 22 secured adjacent the lower end of the shutter, preferably to the pivoted valence section V thereof, and then into the building, preferably through openings in the window frame or other part of the building.

With the shutter in open position, by drawing the chains or operating members 28 inwardly, it will be apparent that the latches I6 will first be withdrawn from the lugs I9 and the slides I5 will then move downwardly in the side members IOA of the shutter and through the action of the thrust bars H the shutter will be inwardly toward the building.

when the operating chains or members 28 are released, and the springs I8 are free to act, the slides I5 will be drawn upwardly in the side members IDA and the shutter will be swung outwardly into the position shown in Figure 6; and

swung as the slides I5 are drawn upwardly, the latches I6 will automatically engage the lugs I8 to lock the shutter in its outward position. When thus locked and the chains 20 tightly secured inside the building, it will be seen that the shutter is firmly held against movement by the wind or other force. When thus locked, the louvers can also be readily operated without disturbing the positidmpf the shutter.

In place of the slides I5, the outer ends of the brace bars I! may carry one or more rollers as indicated at R in Figure 9, which are adapted to move up and down along the'guideways or trackways, these rollers also being drawn upwardly by one or more coiled springs I8A- as in the case of the slides I5.

As previously noted, the shutter may be provided with a louver construction, a simple and convenient form being illustrated in the drawings. This comprises a series of pivoted slats or louvers 25 which are pivotally connected at spaced intervals to the plates I l secured to the side members IIIA. Each of the louvers 25 is also pivotally connected to a common operating bar 26 so thatall the louvers are caused to move simultaneously into open or closed position. Each of the louvers is provided along its upper edge with an outwardly projecting flange and along its lower edge with an inwardly projecting flange. These flanges on adjacent louvers are adapted to overlap and engage and thus form a tight closure in the manner well known. The flange at the upper edge of the top louver is arranged to engage beneath a downwardly and outwardly extending flange on the upper transverse member IIlB of the shutter, and the lower edge of the bottom louver is arranged to engage over an upwardly and outwardly extending flange on the lower transverse member IIlC of the shutter.

The invention includes a simple and convenient means for operating the slats or louvers 25. Secured to the underside of one of the louvers is an anchor plate or member 21 which is bent into a curved or cam shape as shown in the drawings. A coiled spring 28 is connected at one end to the longitudinally of the side member I 0A of the shutter to which the other end of the spring is attached. The inner side of the plate II, heretofore described, is preferably extended inwardly as indicated at I IA to provide a channel in. which the spring 28 is positioned and which also serves to catch and conduct away any water which may be forced inwardly adjacent the ends of the louvers 25. The spring 28 is under tension at all times and this spring tends to rotate the louvers 25 into open position, as shown in Figure 4. An operating chain or cable 29 is also secured to the member 21 at a point opposite the point of attachment of the spring 28. The chain 28 passes over the member 21 in a direction opposite to the spring 28 and said chain preferably extends through an opening in the building so that the same can be conveniently grasped and manually operated from the inside of the building. The member 21 is so shaped as to require the minimum amount of force to overcome the spring 28 and close the louvers and to provide a smoothly operating mechanism fogy' controlling the louvers.

and at the same time it does not detract from the appearance of the shutter.

It will be obs'ervedalso that the mechanism by which the shutter itself is manipulated into open or closed position is practically all concealed within or behind the hollow side-members IOA oi the shutter so that such mechanism is also protected from the weather and is practically invisible so as not to detract from the appearance of the shutter.

Having thus described the invention, what is claimed as new and desired to. be secured by Letters Patent is:
