Application May 3, 1946, Serial No. 667,163

6 Claims. 1 The present invention relates to an awning or jalousie, the construction of which is such that -it is adapted to be integrated from metal parts.

The device comprises a frame having hinged thereto a plurality of louvers which are adjustable, as a group, to vary the degree of admission of light through the device. The invention is primarily concerned with the production of such devices which shall be relatively inexpensive, simple in construction, readily manipulable, capable of easy installation and dismounting, and relatively free from damaging efiects of wear.

Further objects of the invention will appear as the description proceeds.

To the accomplishment of the above and related objects, my invention may be embodied in the form illustrated in the accompanying drawings, attention being called to the fact, however, that the drawings are illustrative only, and that change may be made in the specific construction illustrated and described, so long as the scope of the appended claims is not violated.

Fig. l is a front elevation of an awning constructed in accordance with the present invention, associated with a window;

Fig. 2 is an end elevation of the awning of Fig. 1, the window frame with which it is associated being shown in transverse section;

Fig. 3 is a fragmental enlarged perspective view of a portion of the awning, parts being broken away for clarity of illustration;

Fig. 4 is a transverse section taken substantially on the line 4-4 of Fig. 3;

Fig. 5 is a further enlarged fragmental end elevation of a detail;

Fig. 6 is a perspective view of a rope catch advantageously usable in connection with my invention;

Fig. 7 is an enlarged elevation of a detail; and

Fig. 3 is a view similar to Fig. 4, and showing an adapter intended for use when the louvered structure is installed as a jalousie.

Referring more particularly to the drawings, it will be seen that the device of the present invention comprises a pair of parallel bars I0 and I0. Each of thesebars may preferably comprise an aluminum extrusion formed to provide a laterally projecting protrusion projecting beyond the main body of the bar and defining a pair of tables|2 and I3, lying substantially in a, common plane, upon opposite sides of said protrusion. Centrally formed in the bar I0 is a longitudinally extending, substantially cylindrical trackway I with which communicates a slot I5, opening through the protrusion II, and having a width less than the diameter of said trackway. The trackway M will preferably run the full length of the bar II), as will the slot Reciprocably mounted in the trackway I4 is a rod l6; and a screw ll, entering the slot l5, provides a pivotal mounting upon the rod l6 for one end of a link I8. Said screw likewise secures to said rod IS a frame l9 providing a journal mounting for a pulley 20.

A bracket 2| is pivoted at 22 upon the table i2 of the bar l0; and it will be seen that the arrangement is such that the link I8 is disposed in a plane sufliciently spaced from the table l2 to clear such an element as the bracket 2| supported upon the table. That end of the link |8 remote from the screw I1 is pivotally connected,

as at 24, to the bracket 2| intermediate the ends thereof.

At a point spaced below the pivotal point 22, a second bracket 2| is pivotally mounted upon the table l2; and a second link I8 has one end connected to the rod l6 below the point of connection of the link |8 thereto, and its other end pivotally connected to the bracket 2 intermediate the ends thereof. Further such brackets and links are mounted upon the bar It and operatively connected with the rod H3 in a series of any suitable extent.

Upon the bar It there are mounted, in a similar fashion, brackets corresponding to the brackets just described; and preferably links corresponding to the links I8 and I8 will be operatively connected with said bracekts on the bar I0 and with a rod guided in the bar It. At any rate, each bracekt on the bar ||l will find a mate correspondingly positioned on the bar i0.

Within the upper end of the trackway I4 is confined a coiled spring 26 which continuously resiliently urges the rod IE to move downwardly in said trackway. Suitably fixed to the bar I0 is a bracket 23 to which is fixedly connected one end 21 of a rope or cord 28 which leads from said bracket, beneath the pulley 20, and thence through a suitable fitting 29 to and through the window frame. A mating cord 28' may lead to a similar fitting upon the rod guided in the bar l6.

Fixed to the bracket 2| and to its mate carried by the bar I0 is a louver slat 30. Said slat will preferably be formed of sheet metal, and its forward or lower end will be bent downwardly as at 3|, while its rearward end will be bent upwardly as at 32. Fixed to the bracket 2| and to its mate on the bar is a correspondingly shaped louver slat having its front edge turned downwardly as at 3V and its rear edge turned upwardly as at 32. Obviously, when the brackets are swung downwardly, the upturned edge 32 of the slat 30 will overlap the downturned edge of the slat 39, whereby a very tight closure will be provided against light, breezes, or rain. Fixed to the upper ends of the bars I0 and I0 is an escutcheon slat 33 whose lower edge 34 is inturned for cooperation with the edge 32 of the slat 30.

Of course, similar slats are carried by succeeding pairs of brackets.

The

cords

28 and 28 pass through the window frame and thence through a fitting 35, whence they extend downwardly to and through a catch fitting 36. Such fitting is illustrated in detail in Fig. 6.

The fitting 36 comprises a housing 31, which may preferably be formed of sheet metal, and which comprises a rear wall 38 adapted to be suit-.- ablysecured to the window frame, and a front wall .45. A pivot pin 39, journalled in the side walls of the housing 31, mounts a catch block 40. The rear wall 33 of the housing 3? is disposed in the path of counter-clockwise movement of the end 4|, of the block A0; and a coiled spring 43 is wrapped about the pin 39, one end 4.4 engaging theend 4} of the block 40, and the other end 45 thereof abutting against .the wall lfi, whereby said spring urges the end ill of the block toward eneasement with the wall 33 of the housin Th wall 45 of the housin is slotted, as at 4?, to permit protrusion of the end 52 of the block therethrol h. The ropes 2 3 and 28 are threaded through the housing 3*? between the end 41 of the ,bl ek 4.9 and the wall 38. Obviously, the construction is such that when a downward force is applied to the ropes, they may move smoothly past the end All of the block 4!); but when said 109, 3 8: 16 re ea the sprin 3 Wi l ow th end 41 of the block 46 against said ropes; and n t n ency f h r pes to mo e u wa dly will merely in ea e e l p p o the block end 4 J upon said ropes. When it is desired to .erm-it the ropes to move upwardly, the protrudns end 2 of th lo m y be e ed nw d y,

wa in he end o ai bl k u of gagement with the ropes.

n re.- i h ve how ra ke 48 ecu e to the window frame and to the lower ends of the bars it, to hold said lower ends of said bars outwardly from the window. If it is desired to use the illustrated structure as a jalousie, the arrangement of Fig. 8 is installed. A bracket 49 is associated with each of the arms I0 and ID. Each bracket 49 comprises an arm 50 adapted to be secured, by means of a screw 54 ,to the window frame 52 and a second arm 53 adapted to engage the table it of the associated bar. A thumb screw 54 penetrates said arm 53 and is adapted to be threaded into a suitable opening 55 in the bar Hi, thus securing the lower end of the bar to the window frame.

At the upper end of each bar may be fixed a hinge bracket 55 suitably connectible to a mating hinge bracket 57 fixed to the window frame.
