ADJUSTABLE MOUNTING FOR wmno 'smm Application filed February 9, 1932. seen-m.591,802,;

This invention relates to an improved adjustable mounting for window shades and other devices adapted to be mounted on a window frame, and whereby the adjustment may be easily and quickly made regardless of the width of the window frame, without liability of the release of the window shade or other device from the supporting brackets.

It is a more particular object of the in vention to provide suitable guides for attachment to opposite sides of the window frame, together with brackets adjusting the slides mounted on said guides, and means for connectmg the bracket members w1th said ad-.

justing slides whereby said members may independently assume vertically inclined positions relative to the adjusting slides and the guide. I

It is another object of the invention to provide improved means for mounting a wind deflector and sun shade between and upon said bracket members for adjustment to various inwardly inclined positions relative thereto.

A further object oftheinvention is to provide simple means for securely holding the sun shade in detachably connected relation with said adjusting means therefor, so that it may be readily removed and cleaned or replaced by a new shade. I 1 v With the above and other objects in View, the invention consists in improved adjustable mounting for window shades and like devices, and in the form, construction andv relative arrangement of its several parts-as will the upper end of which is suitably fixed t I Fig. 3 is an enlarged detail horizontal sec tion taken 011 the line, 33 of Fig.2, and

Fig; 4-is a vertical sectional view taken ontheline44ofFig.2. Referring in: detail to the drawing, F indicates a'window frame, and S thefusual Ki; b v

upper andrlower sashes slidably mounted therein. I j

Upon the inner sides of the opposite-verti cal portions of the frame F, and adjacent to G9 the inner face of said frame vertically extending guides-as indicated'at 5arerigidly secured, in; any suitable manner. These 7 guides may, if desired, extend substantially for the full vertical lengthzof-thewindow frame. While the guides 5.1nay be of various mechanical forms'as herein shown,- each of these guides preferably consists of a continuous metal strip ofchannelshape and cross section, having inwardly-turned longitudinalfianges 6 onits opposite side walls."

lVithin,eachguidestrip, a slide bar ,7 a is mounted, and at its upper endis reduced-in width and formed with-an outwardly projecting hook 8thereon. l 75 With each of the guides 5, a bracket plate is associated, said plate having a part 9 overlyingvthe open side of the channelled guide 5, and-a. part 10 preferably ofiiset from the plane of thepart 9, and provided with an 3 V upwardly extending arm 11 having an open.- ing or notch to receive one ofthe trunnions of the windowshade roller indicated at 12;

The part9 of each br'acketplate at its lower end is providedwith' a rectangularly.

opening 13 therein through which the end of the hook 8 loosely-extends and projects into the channel of the guide 5 as indicated at 8'. The lower end of .theadjustingslide 7 for thevbracket plate is provided with suitable latch means for retaining said slide in its adjusted position on the guide 5. As herein shown, the lower end of the slide bar 7 is formed with a horizontally disposed finger F engaging piece 14; projecting outwardly from the open side-of the channelled guide 5; Below this finger fpiece 14,'the latch plate '15 is pivotally supported intermediate of its ends on the lower end of the metal strap l6,

0 loo the finger piece. [One end of the plate 15 extends into the channel of the guide 5 and has an upwardly projecting curved lug 17 thereon which is of a width slightly less. than the distance between the inner edges of the From reference'to Fig. l of the drawing, it will be noted that the inner concave'face of the hook 8is outwardly spaced from the fianges'6 for a distance appreciably greater than the thickness of the metal part 9 of the V bracket, so that the said bracket may assume an obliquely inclined position extending upwardly and inwardlyfrom its lower end relative to the vertical guide 6, the extent of suchinward swinging movement of the bracket plate being limited by a binding contact of the lower edge of the part 9 against the outer faces of the flanges 6; V From the above, it will be evident, as indicated in Fig. 1 of the jdrawing, that the brackets may be independently vertically ads justedon thefopposite sides of the window frame F, and owing to the loose pivotal connection between each bracket in the upper 7 end of the slide bar 7 the bracket at the higher elevation will automatically assume the inwardly inclined position illustrated in the drawing, so as to thereby prevent the release of the shade rolle'rotrunnion from engagement in the bracket arm 11. It will be evident that this is a feature of importance in the application of such adjustable shade brackets to windows of considerable width which may render it very difficult, if not impossible, to simultaneously adjust the two brackets and maintain the same substantially at equal distances from the top of the window frame in the adjusted operation.

As an. additional advantageous feature, I haveshown a sun shade generally indicated at 19 supported upon the parts 10 of the brackets for adjustment to various inwardly inclined positions relative to said brackets and theshade roller 12. The shade 19 may consist of a sheet of muslin, canvas or other material more or-less impervious toair, but sufiiciently obstructing the passage of light or the suns rays to prevent an undesirable glare at a certain point in the room or apart- 1 ment, depending upon the position of said shade. The opposite longitudinal edges of this sheet of material have the stiffening rods indicated at 20 and 21 respectively se- A suitable form' of spring,

cured therein, the rod 21 having terminal eyes shown at 22 for the purpose to be presently explained. The end edges of the sun shade are provided with the loops shown at 23 to receive adjustable supporting means mounted on the parts 10 of the adjustable bracket members. As herein shown, this supporting means may consist of rods 24 having eyes 25 on one of their ends loosely.

surrounding the threaded studs 26 afiixed in the parts 10 of the respective bracket members and projecting inwardly therefrom. Clamping nuts 27 threaded onsaid studs are adapted to frictionally bind against the eyes 25 and thus securely clamp the nuts of the rods to the bracket members, whereby the shade 19 willbe supported at the desired inclination.

Coil springs 28 are attached at one of their ends to the eyes 22 on the rod 21, and have their other ends suitably attached to the. nuts 27 as shown in Fig. 3, or if desired,

may be securedto the parts 10 of the bracket members. Preferably, the springs 28 have a readily releasable hook connection with the eyes 22, so that when desired, these.

springs may be disconnected from said eyes and thus permit the shade 19 to be readily removed from the supporting rods 24.

From the above description, it will be readily seen, as indicated in'Fig, 2 of the drawings, that the shade 19 may be easily and quickly adjusted by means of the clamp ing nuts 27 to variousangular positions so as to obstruct the direct rays of the sun. By

positioning this shade in the upwardly in-V clined position extending above the opening at the top of the upper sash indicated in broken lines in Fig. 2, adequate ventilation may be obtained at the top of the window.

whileiin the event of heavy winds, they will be deflected upwardlytowards the ceiling of the room. Thus, it will be evident that ,my present invention provides a device of this kind of great convenience andserviceability. At the same time, the several parts thereof, are of comparatively simple mechanical form, and enable the device to be manufactured and sold at comparatively small cost.

While I have herein shown and described a practical embodiment of the invention which has given excellent results in actual use, it is nevertheless to be understood that in so far as the essential features of the present disclosure are concerned, the same might also be incorporated in various other alternative structures, and I accordingly reserve the privilege of adopting all such legiimate modifications as may be fairly embodied within the spirit and scope of the invention as claimed. r

' I claim; y 1. In a device of the character described, a guide adapted to be attached to. one side of a window frame to extend vertically thereof, a supporting bracket, manually adjustable means vertically movable along said guide, and means connecting said bracket with said manually adjustable means normally supporting the bracket in parallel relation to the guide and cooperating with the bracket and the guide to support said bracket for movement to and from a laterally inclined position out of parallel relation with the guide. 7

2. In a device of the character described, a guide strip adapted to be attached to a window frame to extend vertically thereof, a manually adjustable slide bar mounted on said guide strip, a shade supporting bracket having an opening, and said slide bar at oneend having a hook formed thereon loosely projecting through the opening in the bracket and co-operatlng with said guide strip to support the bracket for vertical movement with the slide bar and for movement relative thereto to a laterally inclined position out of parallel relation to the guide strip.

3. In a device of the character described, a slide member adapted to be mounted for vertical adjustment upon one side of a window frame, a window shade supporting bracket, and relatively movable coacting means on one end of said member and said a bracket normally supporting the bracket in parallel relation to said member and establishing a loose connection therebetween, whereby said bracket may assume a laterally inclined position out of parallel relation to said member upon displacement of the window shade roller from a normal horizontal position;

In testimony that I claim the foregoing as my invention, I have signed my name hereto.

NATHAN SLOBOTKIN.
