AWNING Filed Sept. 25, 1948 INVENTOR.

Patented May 20, 1952 UNITED STATES PATENT OFFICE AWNING Arthur Chrosnik, Chicago, Ill.

Application September 25, 1948, Serial No. 51,131

This invention relates to improvements in awnings and more particularly to window awnings although adapted also for other applications. One object is to provide an awning that is easy of operation, noiseless and that will regulate the admission of light and exclude rain. A further object is to provide an awning of the louver type that may be operated from inside or outside the house or other structure to which applied and one wherein an adjustment to admit any desired light will retain its adjusted position until released.

A further object is to provide an awning having louvers that may be individually removed, reversed in case of warp and one that will shed outwardly such water as may fall thereupon and that is devoid of water pockets. A further object is to provide an awning that is positive and efficient in operation, inexpensive to manufacture, readily applied to or removed from a window or other surface, that is easily cleaned, painted or sprayed and one wherein all parts are so accessible as to be readily reached for repair or replacement when necessary.

My invention resides in the arrangement and combination of parts and in the details of construction described in the specification and particularly pointed out in the appended claims. It is understood that I do not limit myself to the precise embodiment of the invention shown herewith as various changes may be made within the scope of what is claimed without departing from the spirit of the invention. I intend no limitations other than those imposed by the claims.

In the drawing:

Fig. 1 is a view in perspective ofawnings embodying my invention and showing the louvers both open and closed and illustrating its application to a residence or similar structure.

Fig. 2 is a detail sectional view, enlarged, on the line 22 of Fig. 1.

Fig. 3 is a detail sectional view similar to Fig. 2 but showing a slightly modified structure.

Fig. 4 is a detail sectional view taken on the line 4-4 of Fig. 1.

Fig. 5 is a fragmentary view of Fig. 4, enlarged.

Fig. 6 is a fragmentary face view of Fig. 4 with parts broken away.

Fig. 7 is a fragmentary view of a slightly modified form of Fig. 2, and

Fig. 8 is a view of Fig. 3 but with adjustable parts in an altered position.

The reference numeral I denotes a portion of a structure to the windows of which the awning may be applied. Suitably secured to an overhang 2 of the structure are the spaced outwardly and downwardly disposed parallel hangers 3 pref erably covered with some suitable material such as a weather protecting fabric or the like. Refer- 5 ring now to all figures except Figs. 3, 7 and 8 the hangers 3 are further supported by braces 4, 4' secured to the face of the structure or to the window casings, the hangers and braces forming the awning framework, the terminal braces being 10 preferably wider than the intermediate ones.

Pivotally secured to adjacent hangers 3 upon pins 5 are the louvers 6 that extend from hanger to hanger and that overlap in closed position and that in open positionmay be spaced apart to a greater or lesser degree depending upon the angle of the louver so that light as desired may be admitted through the louvers and through the window protected by the awning. The louvers between any two hangers form a unit and are adapted for operation independently of any other unit of the awning assembly, the louvers spaced from their hangers by the anti-friction collars 3a. The two terminal louvers of a set, one at the top and one at the bottom of each unit are each connected by a hinge I to an actuating bar 8 which bar is formed along its outer longitudinal edge with notches 9 at spaced intervals, said notches spaced apart by riser portions I6 said notches receiving the inner longitudinal edges of the louvers to form a friction hinge connection therewith, the risers between notches being inclined to keep the louvers seated in the notches. The space between adjacent notches is substantially equal to their distance from the hanger in the wide open position of the louvers clearly shown in Fig. 4 so that in their closed position, shown in Fig. 2, they rest upon and overlap each other.

Secured to the inner longitudinal edge, which is a straight edge, of the actuating bar 8 by the hinge H is the sectional lift elbow I2, the meeting sections thereof connected by the hinge 13, said elbow connected by the hinge M to the structure l. Extending through a slot in the lift elbow is the lift cord l5 that beneath the elbow is knotted as at "5 to prevent withdrawal of the cord, said cord passing about a small sheave I1 secured to overhang 2 and to and about the shaft of a spool l8 that extends through the window casing or wall and within the structure terminates in or is integral with the ratchet l9 having handle 2 0 for rotating the spool manually to wind the cord thereupon. With the cord partially unwound from the spool and the lift elbow sections 5, angularly disposed or partially folded substantially as shown at Fig. 4 the louvers are wide open to admit the maximum light and air. To close them the spool is manually rotated to wind the cord thereupon until the lift elbow is fully extended and the louvers folded upon each other into closed position as shown in Fig. 2. The ratchet will releasably retain the movable parts in any intermediate position in well known manner. Instead of the spool and ratchet the cord I5 may pass from the sheave I 'Lto andbe Wound about the post 2| secured to a wall of the structure or to the Window casing.

Referring now to Figs. 3 and 8 a slightly modifled form is shown wherein a rod 22 connected by hinge 23 to the structure I is slotted to permit passage therethrough of the cordf'24' knotted at one end and that passesover sheave..25.and.

is secured to the anchor 26 fast to structure I'.

A roller 2'! at the free end of the rod.22 bears" 29 is provided for ornamentation. A cushioned stop block 35 depending fromithe overhang in the path of movement of the topmost. louver may be gently engaged thereby or will be contiguous thereto at the end. of the forward or closing movement, of that louver.
