BLIND OR AWNING CONSTRUCTION.

Application filed September 14, 1925. Serial No. 56,109.

This invent-ion relates to new and useful improvements in blinds and it pertains more particularly to a blind which is adapted for use on the exterior of a door or window opening-and is in the nature of an awning.

An awning as commonly constructed, comprises a canvas hood like structure supported over the upper portion of a door or wlndow opening and adapted to be lowered to artially close the door or window opemng. This type of awnin while effective in shutting off strong lights, also has the disadvantage of cutting ofi' too much of the light. Furthermore an awning ,of this character interferes to a great extent with the ventilation through the door or window opening when the awning is lowered and also in many cases when the awning, is in its raised position. v Awnings have beenproduced comprising a series, of parallel slats secured together to form 'a slat structure anda'rranged to be applied to'a door or window with the lower part of the slat structure spaced from the door or window so that the slat structure extends at an angle from the upper portion of the door or window opening.

As far asapplicant is aware, awnings of this type have not been provided with adjustments for varying-the passage of light or air through the same. Also in such prior awning structures, the lower part of the,

awning is located inspa'ced relation to the window by a manual operation independent of the raising and lowering operation.

It is one of the objects of the present invention therefore to provide an im roved awning construction by which'both t e vol.

ume and degree of light and ventilation are 40 at will.

Another important object of the. invention is to provide an improved awning of the Venetian blind type in which the'lowerpart lation to the door or window automatically during the lowering operation to locate the awning in an inclined "position.

Another object of the invention is to provide an improved awning construction of the Venetian blind type in which the awning may be located in'an inclined position with relation to the door or window or in substantially parallel relation thereto as desired.

'ing; and

at all times under control and'may bevaried" of the awning will be located in spaced re- With these and other objects in view, the invention comprises certain novel and improved features, construction andwornbinations of parts hereinafter described and particularly pointed out in the claims, the advantages of which will be readily understood and appreciated by those skilled in the art.

The invention will be clearly understood from the accompanying drawings illustrating the invention in its preferred form, and the following detailed description of theconstructions therein shown.

Referring to the drawings,

'Figure l is a perspective view of a window showing a blind or awning constructed in accordance with the present invention in place thereon, the blind 'or awning being partially extended;

Figure 2 is a view in front elevation of the blind or awning showing the same in its fully extended position; v

.Fgure 3 is a longitudinal sectional viewtaken on the line 33 of Figure 2;

Figure 4 is a view in front elevation showing the blind in completely folded position;

Figure 5 is a detail longitudinal. sectional. view taken on the line 55 of Figure 4;

Figure 6 is a view in end elevation showing the upper portion of the blind or awn- Figure 7 is a top plan view of the upper portion of the blind or awning.

In the accompanying drawings, the reference numeral 10 designates a window, the frame and sill thereof being designated by no the reference numerals 11 and 12 respectively.

The blind or awning is, generally speaking, of the Venetian type and comprises a plurality of slats 13, secured between tapes 14 in such a manner that when the blind or awning is extended the slats will occupy positions in which they'are spaced with respect to each other, or when the blind is folded, the several slats occupy positions in contact with each other. In addition to the foregoing, the slats 13 when the blind or which bar extends across the upper -portion of thewindow frame 11.

To adjust the several slats in difl'erent angular positions this bar is rocked about a horizontal or longitudinal axis, and to provide for rocking movement of this bar each of its ends is provided with a pivotpin 16, which pins 16 engage inopenings in brackets 17 and 18.

15 when the several parts are in fully assembled positions.

Passing over the pulley 19 there is a cord 23, and this cord 23 is attached at its lower end to the lowermost slat 24 of the blind or awning nearer one end thereof and extends upwardly through openings 25 in the several slats 13, these slats 13 being provided with the openings 25 near @each end. Connected at its lower end to the lowermost slat 24 of the blind at a pointnearer the end thereof opposite that to which the cord 23 is attached, there is a cord 26, and this cord 26 passes upwardly through openings 25 in the slats 13 and over the pulley 20. Both of'these cords 23 and 26 pass over the pulley 21, and one of said cords extends downwardly preferably to a point adjacent the base of the window or door opening where it may be conveniently grasped, the

other cord being attached to the latter. cord as at 27 (see Figure 2). By exerting a pull upon that cord which is extended toward the base of the door or window opening, the

lowermost slat 24 will be raised, and the several slats will be brought with their fiat sides in contact with each other to the position shown in either Figure 1 or Figure 5,

' depending, of course, upon the extent of movement imparted to the extended cord.

As heretofore stated, the transverselyextending bar 15 is adapted for rocking movement about its longitudinal axis, and

" this movement is produced by means of a looped cord, the two ends of which are connected to the forward edge of the transversely-extending bar 15,.as at 30. One part.

27 of this looped cord, passes'from its'point of attachment to the bar 15, over said bar and then downwardly while the other part 28 of the cord passes under the bar 15, then over a pulley 29 carried by the bracket 17 and then downwardly. This construction and arrangement of parts permits of rocking the. bar 15 in either direction from a horizontal position approximately one-quarter of a revolution to tilt the slats 13 by pulling respectivel upon the parts 27 and 28 of the cord, the direction of movement depending upon which part of the cord is pulled.

The'bracket 17 comprises a base portion 31, a depending end portion 32, (see Fig. 4) which pivotally supports one end of the bar 15 said end portion 32 being provided with an opening 34 for the reception of the pin 16 on the end of the bar. The bracket is also formed with depending projections 33 and 35, between which the pulley 29 is mounted. The projections 33 and 35 are located to the rear of the bar 15 as more clearly shown in Figs. 3 and 6 so as to locate the pulley 29 in the proper operating position with relation to the bar 15 and so as not to interfere with the tilting of said bar.

The bracket 18 heretofore mentioned which Ill of the pin 16 carried by the other end of the I barL15.

These two brackets 17'and 18 are preferably secured to the under side of the transversely extending bar 16, thereby suspending the tilting bar and slats from said bar 16.

In the present awning or blind construction, devices are provided for controlling the position of the lower part of the blind, which upon lowering the blind from its upper position at the top of the window opening to redetermined points in-said window opening will automatically operate to space the lower'part of the blind at predetermined distances from the window as shown in .Fig. 1 to locate the blind in an inclined position. Upon lowering the blind still further, these devices will cause the lower part of the blind automatically to swing in toward the window frame until when the blind is in its lowermost position, it Will lie substantially parallel with the window frame as shown in Fig. 3.

The devices for controlling the position of the lower portion of the blind in the manner.

above'des cribed comprise two supports, one located on each side of the blind. Inasmuch as these supports are of substantially the same construct-ion, a description of one will suffice for both.

These supports comprise a rod 42 pivotally engaged in openings in projections on a bracket 40. This rod comprises a part 43 which is bent at an-angle to that part. of the- 45 and the part 43 of the rod forms a stop limiting this telescoping movement.

\Vith the above construction, whenthe blind is raised to its uppermost osition', the

- stantiall parts of the devices for control ing the position of the lower part of the blind will assume substantially the positions shown in Fig. 5. In lowering the blind, the cords 23 and 26 are slacked off and the blind will descend under the action of gravit As the blind descends, the rods 42 will telescope within the tubular" members 45 until the parts 43 of the rods engage the ends of the tubular members, the blind descending subparallel with the window frame during t is part of its downward movement.

' Vhen the ,telescoping of the rods 42 -within the tubular members has thus been arrested,

upon. further downward movement of the'- blind, the rods 42 and members 45 will sw'ing' outwardly about pivots 46 and the lower part of the blind thereby will be caused to swing butwardly awa from the window frame into an incline position, as shown in Fig. 1. When in this position, the blind forms an inclined'awning over the window and its slats may be adjusted in any desired inclined position for the purpose of admit tin or excluding'air or light.

fr it'is desired to allow the blind to descend until it=covers completely the window opening, the cords 23 and 26 are further slacked ofi', allowing thelower art of the blind to descend still further. uring this further downward movement, the tubular members 45 and rods 42 will swing inwardly about the pivot 46, thereby causing the lower part of the blind to swing inwardly, until when the blind has descended to its lower portions 27 or 28 of the tilting cord whether sition the awning is located in an inclined position with relation to the door or window or whether-the awnin is located substantially parallel thereto. T us the angular positions of the slats may be adjusted to regulate the admission of light and air with the awning in any of its various ositions.

The awning may located in various inclined positions with relation to the door or window by stopping the descent thereof .at various points after the lower part of the awning starts to swing out away from the window in the manner described above. It will be understood, of course, that the blind or awning is maintained in its adjusted poby securing the cords 23 and 26 by which it is operated.

It is to be understood that the invention is not limited to the particular construction and arrangement of parts of the illustrated embodiment of. the inventionbut that the invention may be'embodied in other forms I within the sco e' of the claim.

Having exp ained-the nature and object of the invention and having scribed a construction embodying the invention in its preferred form, what is claimed Z i In a blind and awnin construction comprising a series of para el slats, means for supporting said slats adjacent a door or window opening, and means for raising and lowering the bl nd, a swinging support for the lower end of the blind made up of two or more. parts telescopically connected and a stopto limit the telescoping movement of said arts so that in raising or lowerin the -blin the blind is first moved substantially.
