WINDOW SHADE HOLDER Filed July 17, 1950 E min A. Raasch INVENTOR.

BY WW Z5? Patented June 12, 1951 UNITED STAT S PATT OFFICE The present invention relates to certain new and useful improvements in structural ways and means which serves to coact with and confine the vertical edge portions of a drawn window shade in a manner to prevent the latter from ballooning and noisily flapping within the confines of a room space.

It is a matter of common knowledge that when a roller-type window shade or blind is pulled down, either partly or wholly, and the sashes are opened, air entering the room from the outside will often blow, flap and tear the shade. Everyone knows how exasperating and nerve racking flapping window shades can be. The obvious purpose of the present invention is to provide simple and practical holders which are susceptible of being installed in conventional frame constructions and which are characterized by projectable and retractible check rails which virtually eliminate shade flapping.

A further object of the invention is to structurally, functionally and. otherwise improve upon shade edge guides and similar devices and, in so doing, to provide novel and practical'means in which manufacturers, users and others will find their ordinary needs fully met, contained and readily available.

Briefly summarized, each holding device is characterized by a vertically elongated sheath which is channel-shaped in cross-section, a projectable and retractable check-rail of corresponding length, and a pair of simple hingedly mounted end brackets in the sheath permitting the checkrail to be projected for use and retracted when not in use.

Other objects and advantages will become readily apparent from the following description and the accompanying illustrative drawings.

In the accompanying drawings, wherein like numerals are employed to designated like parts throughout the views:

Figure 1 is a fragmentary view with parts shown in section wherein a shade holder, constructed in accordance with the invention, is shown mounted and in use.

Figure 2 is a view on a smaller scale showing the complete frame, sash, shade assembly with both shade holding devices projected and in use.

Figures 3 and 4 are horizontal sections on the planes of the lines 33 and 44 respectively of Figure 1, looking in the direction of the arrows.

Figure 5 is an enlarged fragmentary perspective view, with portions broken away, showing one end portion of one of the attachments.

Referring now to the drawings by reference 6 Claims. (Cl. 160-268) numerals and lead lines and directing attention first to Figure 5, the channel-shaped sheath is denoted by the numeral 6. In practice, this is of suitable material and is approximately of a length corresponding to the height of the window construction in which it is installed. The spaced parallel side walls are denoted by the numerals 8 and I0 and the web portion [2 is provided with apertures or holes M to accommodate wood screws or the like which are used to fasten the sheath unit fixedly in operative position. The complemental projectable and retractible check-rail unit is denoted by the numeral Hi. This is of a length substantially commensurate with the length of the channel into which it folds. It is also V-shaped in cross section and the flange portion I8 is adapted to recede wholly into the confines of the channel as shown in Figure 3. The head portion 20 substantially lids over and closes the open side of the channel. In Fig. 3 the rail unit [Bi shown fitting into the channel. In Fig. 4 it is shown projected outwardly beyond the channel in which position it serves as a guard. A block-like bracket 22 is hinged at 24 between the upper end portions of the flanges and this bracket is bifurcated and the furcations provide ears 26 which straddle and are eccentrically pivoted as at 28 to the flange [8. The flange I8 is provided with a clearance notch 30 which serves to clear the bracket 22 when the parts are folded I into the sheath. There is a similar hinged bracket at 32 and this is likewise hinged between the flanges and provided with ears 34 straddling the flange l8 and hingedly connected thereto as at 36. The hinge means here is provided with a knurled or otherwise milled finger grip 38 which may be employed as a sort of a turning knob. That is to say, by catching hold of the knob and turning it in a direction from left to right, the two brackets are swung upon their hinge joints and serve to project the guard unit I6 to an out position, the position shown in Figures 1, 2 and 4. Turning the knob in the opposite direction actuates the brackets simultaneously and serves to cause the brackets to recede between the channel walls, whereupon the unit i6 is thus retracted to an out-of-the-way position. In the latter position which is shown in Figure 3, the guard is clear of the edge portion 40 of the roller type shade or blind 42.

In practice, the channel-shaped sheaths 6 are nailed or otherwise fastened to accommodating strips 44 in the window frame. The sashes are of usual construction and for convenience are denoted by the numerals 46 and 48. Obviously,

the sashes, frame and window blind are conventional. This invention merely adds to guard attachments and they are shown in useful positions in the arrangement depicted in Figure 2.

A careful consideration of the foregoing description in conjunction with the invention as illustrated in the drawings will enable the reader to obtain a clear understanding and impression of the alleged features of merit and novelty sufficient to clarify the construction of the invenion as hereinafter claimed.

Minor changes in shape, size, materials and rearrangement of parts may be resorted to in actual practice so long as no departure is made from the invention as claimed.

Having described the invention, what claimed as new is:

1. In a window construction of the class and described, in combination, a relatively stationary frame structure, windows mounted in said frame structure, a rollable shade'mounted-in said frame structure, said shade being provided at its lower end with a customary hem and stick in the hem, a pair of opposed vertically disposed channelshaped sheaths mounted in vertical portions of said frame structure adjacent to the marginal edges of said shade, check-rails occupying positions which overlap the vertical edge portions of the shade, and hinged brackets connected with the respective sheaths and associatedcheck-rails and facilitating folding of the latter to positions which are out of the way in respect to the edge portions of said shade.

2. A shade guard attachment for a window frame comprising a sheath adapted to be fixedly mounted on a vertical part of a conventionaltype window frame construction, a projectable and retractible check-rail, and means fastening the rail in the sheath and permitting the rail to fold against and partly into the sheath retract the latter into an out-of-use position.

3. An attachment for a window frame construction comprising an elongated channelshaped sheath, brackets hingedly mounted in opposite end portions of said sheath, an elongated check-rail provided with a flange, said flange being hingedly connected with said brackets, the brackets and flange being foldable into the channel of the sheath when not in use.

4. An attachment for a window frame con- I struction comprising an elongated channelshaped sheath, brackets hingedly mounted in opposite end portions of said sheath, an elongated check-rail provided with a flange, said flange being hingedly connected with said brackets, the brackets and flange being foldable into the channel of the sheath when not in use, one of said brackets being provided with a fingergripping knob whereby upon operating the single knob both brackets are swung to projected positions in the manner and fOr the purposes described.

5. An attachment for a window frame construction comprising an elongated sheath of channel-shaped cross-section, upper and lower brackets hingedly mounted between the flanges of the sheath at opposite end portions of the sheath, said brackets being provided with spaced ears, one'of said brackets being provided with an operating knob located on the exterior of the sheath, an elongated check-rail of T-shaped cross-sectional form and including a head portion and a flange portion, the flange portion being hingedly connected with the brackets and adapted to fold into the channel when out of use.

6. In a window oonstruction'of the:class shown and described, in combination,'a'relatively stationary frame, a roller-shade mounted. "in the upper portion of said frame,.and means-mounted on the vertical portions of said frame/to coact with the vertical edge portions'of :said shade to prevent strong air currents from ballooning and flapping the shade into the adjacent room space, said means embodying vertically elongated check-rails, fixed channelehaped sheaths therefor and hingedlymoiintedreceding brackets foldable into said sheaths, said brackets supporting said rails.
