ROLLER-BLIND SUPPORT FOR CASEMENT WINDOWS.

Application filed December 22, 1925. Serial No. 77,081.

Our invention relates to improvements in roller blind supports for casement windows, and the object of the invention is to devise a roller blind support for casement or French windows which will not interfere with any of the ordinary fixtures, which Wlll enable the blind to hang close to the glass, in which the support for the draperies extending both in front of and at the back of the blind will be provided for, and in which the lock of the casement window will not be interfered with, and it consists essentially of the arrangement and construction of parts as hereinafter more particularly described.

Fig. 1 is a perspective view of the casement window showing our device applied thereto.

Fig. 2 is a sectional plan view through Figure 1 showing our device in full.

Fig. 3 is an enlarged transverse sectional view through our roller blind support showing the roller blind by dotted lines.

Fig. 4 is a plan sectional detail through the adjustable portions of our roller blind support and showing the means for locking the parts in the adjusted position.

Fig. 5 is a sectional view through our support on line 5-5, Figure 2.

In the drawings like characters of reference indicate corresponding parts in each figure.

1 is a bracket which is hingedly mounted at 2 to the frame of the casement window; a bracket 1 being provided at each side of such frame. 3 arearms extending horizontally from the bracket and preferably formed of sheet metal having the edges rolled inward as indicated at 4 and v5 to form a guideway.

6 is an extension which is also formed of sheet metal and is provided with corresponding rolled edges 7 and 8 which fit within the rolled edges 4 and 5 so that the part 6 is slidable longitudinally with the part 3. The outer ends of the portions 6 are provided with depending supporting members 9 from each of which extends a rubber bumper member 10 adapted to engage the sash 11 of the casement window adjacent its free edge.

12 and 13 are brackets provided with upwardly extending tongue portions 12 and 13 14 is a curtain hanger of the usual type formed of two members telescopically engaging one with the other as indicated at 15, the ends of the hanger being provided with slots 16 into which the tongues 12 and 13* enter so as to support the curtain hanger in place.

17 is a back curtain hanger which is supported at its ends on the bracket member 1 and supporting members 9. The back ourtain hangers may also be divided into two portions telescopically connected together as indicated at 18.

19 is a lock washer oval in form, the major diameter being slightly larger than the width between the sides of the extension 6, the minor diameter being less than such width. The washer 19 is provided with a central transverse slot 20.

By turning the washer 19 into position shown in Figure 4 the sides of the portions 6 are slightly spread so as to frictionally engage the sides 4 and 5 of the arms 3 and thereby prevent the longitudinal movement of the extension 6 within the guides formed by the sides 4 and 5.

When it is desired to adjust the roller blind support so as to fit any desired width of window, the washer 19 is turned to a position at right angles to the position shown thereby freeing the extension 6 and permitting it to slide to the desired position so as to either extend the width of the support or shorten it.

The portions 9 are provided with slotted openings 9 and 9 and the bracket 1 is provided in its opposing face with correspond ing positioned recesses 1 and 1 into which the usual supporting pintles of the roller blind 20 extend.

In setting up our device the members 3 and 6 of the support are adjusted to the required position and the hinge 2 secured to the frame of the easement window. The roller blind of a corresponding width required for the window is then inserted in the usual manner in either orifices 1, 9 or 1", 9 according to how close it is desired to place the blind to the Window.

It will thus be seen that when the blind is mounted as above described it may be swung outward free or independently of the casement window sash so that it will not interfere in any way either with the sash or its fixtures, and at the same time our device forms a support for the inner and outer curtains which are swung outward with the blind support.

From this description it will be seen that we'vhave devised a Very simpledevice adapted for supporting roller blinds in front of a casement window so that it will be swung independently thereof and yet held. clear of the window so that it will not interfere in any way with its securing lock or other fixtures and which may be readily adjusted to any width of sash and securely locked in its adjusted position.

What we claim as our invention is:

The combination with a Window frame, of

bracket formed integral with the outer end of the other extensible member and between which and the first mentioned bracket a shade roller is adapted to be mounted, an

extensible curtain-support, and means for detachably connecting said curtain support either to the inner or outer face of the aforesaid brackets.
