PATENTED 61975 INVENTOR Jeff H. Small ATTORNEY CLOSABLE SHADE COWL PROVIDED CURTAIN HANGER BRACKETS BACKGROUND OF THE INVENTION The invention is unique in that the prior art, as searched, shows no cowl with hinged closure, that completely obscures the conventional roller shade therewithin in releasably latched, operative position, while at the same time providing curtain hanger brackets. Thus, all that is necessary to mount shade for use with curtains ready to be hung thereabout, is to connect top member 'of a window frame. The nearest prior art reference appears to be Allen US. Pat. No. 711,455 that expired Oct. 21, 1919.

The cowl solves several problems, primarily, it prelocates the curtain hangers with respect to the shade mounting brackets. Also, it provides an ornamental cowl that receives the shade completely therein, except for the pull string ring, when the shade is completely rolled up, and at the same time permits the shade to be drawn downwardly, passing with slightly clearance between the backplate of the cowl and the inner surface of the hinge cover. Also, it provides means that assuredly maintains the shade latched in operable position, while the hinge cover can be raised to permit the latching means to be manipulated to permit the shade readily to be removed downwardly. The invention introduces a new structure of interior decoration classification, while serving the aforesaid several utilitarian functions that may be appreciated by design architects.

SUMMARY OF THE INVENTION The invention relates to a window shade cowl with hinged closure, and closed ends providing curtain hanger brackets, the window shade being mounted to be releasably latched in occluded position within the cowl when the shade is completely rolled up.

As a primary object the invention sets out to provide a cowl designed to provide curtain hanger brackets on its ends, with shade mounting brackets within the cowl, which has a hinged cover completely to occlude the shade when rolled up, and to permit the shade to be rolled downwardly through slight clearance between cowl back plate and hinge cover.

It is also another and important object of this invention to provide a shade mounting cowl of this class with pre-located curtain brackets affixed thereto, whereby the means for conjointly mounting shade and curtains for predetermined can be affixed in proper place with relation to structure, as the upper member of a window frame, simply by affixing the cowl thereto, as at two prelocated points.

It is yet another object of the invention to provide shade mounting brackets within cowl, adapted to have releasably latching means manipulated together with shade supporting means on brackets pivoted, whereby the shade can be readily removed.

' It is also a further object of the invention to provide a cowl of the class described which can have all component elements, as back plate, cowl plate, and cowl end closure all blanked from a single sheet of material, as aluminum, or specially appearing steel.

It is yet another object of the invention to provide a cowl of this class which can be readily adapted to provide special shade mounts, and special curtain brackets.

Other and further objects will be apparent when the invention is considered in relation to the drawings, in which:

FIG. 1 is an isometric view from inside, of the top, hinged cover, and an end of the cowl, to small scale, with shade pulled partly down over a window, no curtains being shown;

FIG. 2 is an isometric view, from inside, of a cowl as described shown in FIG. 1, and with curtains installed on a conventional curtain hanger, the conventional curtain hanger end engagement with the cowl provided curtain hanger brackets thus being occluded;

FIG. 3 is a large scale isometric view of a cowl of the class described, showing back plate, cowl plate, part of hinged cover, and end closures, with a shade mounted in the brackets therefor, the right end of the shade being omitted, better to show bracket construction and latching details, in corresponding fullness as shown for the left end bracket and latch construction;

FIG. 4 is a transverse sectional elevational view, partially diagrammatic, as if taken through the left end portion of the cowl shown in FIG. 3, just inwardly of the end closure, with angle bracket outline omitted, better to show latching details, however in this view the cowl side closure configuration appears, for purposes of illustration, as a variation of the corresponding conshown in FIG. 1 as comprised of a back plate 11 outwardly, or against wall 12 and upper window frame member, not shown; and end closure 13a, a cowl member 14, a hinged cover 15 connected to the cowl member 14 by a hinge 15, and as shown closing the lower part of the cowl. The lower part of the shade 16 is shown drawn by pull ring 21 downwardly over the greater part of the upper of the window panes 17 of the window 18. The left curtain rod hanger 19 of the opposed pair of curtain rod hangers carried by the respective cowl end closures 13a, 13b, is also indicated to small scale in FIG. 1. As shown in FIG. 2, a curtain rod 22 is installed on brackets, not shown, as the bracket 19 shown in FIG. 1, and curtains 23a, 23b, are shown, in conventional use.

Referring now to FIG. 3, the inner details of the cowl 10 may be seen, with special brackets 24a, 24b, left and right, including angles 25 shown affixed to the cowl outer or back plate 11. Pivot arms 26a, 26b, are pivotally mounted on

respective pivots

26c, 26d, on the upstanding legs of the respective bracket angles 25, with the left pivot arm 260 having a slot 27a therein to receive the conventional lug 28 of the shade rod or inner member 29. The opposite, or conventional pin end of the rod 29, not shown for reasons of clarity, is received in a suitable hole or bore 27b in the right pivot arm 26b. A releasably latching means 30a, 30b, is shown in FIG. 3 for each pivot arm 26a, 26b, respectively, the latching means 300 on the left being shown as comprising a latching arm 31a pivotally connected about a pivot 32 which extends inwardly from the cowl end closure 13a to provide the pivot mount for the upper end of aforesaid latching arm 310.

A latch pin or rod 330 is shown extending inwardly from the free end of the latching arm 31a and substantially normal thereto and in latching contact with the lower surface of the pivot arm 26a, thus to dispose the slot 27in the pivot arm 26a with axis in substantially horizontal position. Thus the lug 28 at the outer end of the shade rod 29 is shown in FIG. 3 as releasably, latchably retained against rotation in the slot 27. As this occurs the pin in the opposite end of the shade rod 29 fits in the hole or bore 27b in the pivot arm 26b, while this pivot arm 26b, right side, is shown in FIG. 3, as retained by a latch pin or rod 33b, corresponding in function with the latch pin 330, left side, thus to hold the pivot arm 26b retained in releasably latched position. As shown in FIG. 3, the right latch pin 33b has an inwardly projecting grasp or handle part 20, which is easily urged upon for disengagement, as will be hereinbelow described. Correspondingly such a handle part 20 may be provided for the left latch pin 33a.

Referring now to FIG. 5, showing the left end of a conventional shade operating mechanism 35, a torsion spring 34 is shown having its inner end affixed to the shade rod 29 and its outer end affixed to an inwardly extending hub 36a of the shade roller 36 to which the conventional shade sheet 16a is affixed along a line extending longitudinally along, or parallel to the axis of rotation of the shade rod 29, as this shade rod 29 is held against rotation by the engagement of the lug 28 in the slot 27 The conventional shade sheet 16a, FIG. 3, is shown as having its pull ring 21 connected by pull string 21a, to a lower cross stick 21b in a hem 21c provided to extend across the shade sheet 16a. Starting with the shade sheet 16a rolled up around the shade roller 36, as the shade sheet 16a is pulled downwardly, as by the manual exertion of a pull upon the pull ring 21, the shade sheet 16a, connected at its inner end along the shade roller 36, will cause the shade roller 36 to rotate in counterclockwise direction, FIG. 5. Thus the tension is tightened or increased in the torsion spring 34 as it winds up in more turns around the shade rod 29. If the downward pull on the shade sheet 160 is with any degree of force, such pull will cause the shade roller 36 to rotate with enough speed to urge the cam pins 37a, 37b, pivotally mounted on the outer face thereof, to pivot outwardly responding to centrifugal force, thus to permit the shade roller 36 to clear the latch cam 38 provided on the shade rod 29 just inwardly of the lug 28. Whenever the motion of the shade sheet 16a is substantially slowed, the cam pins 37a, 37b, will pivot toward the axis of rotation so that one of them engages the latch cam 38 to stop the rotation of the shade roller 36.

Conversely, when the shade sheet 16a is moved enough to effect cam pin 37a or 37b disengagement with latch cam 36, and then released, the torsion of the wound torsion spring 34 will take over and rotate the shade roller 36 in clockwise direction with speed that causes the cam pins 37a, 37b, to take disposition sufficiently outwardly by centrifugal force to permit clear rotation of the shade roller 36 about the shade rod 29, as long as the shade movement is not impeded to result in cam pin 37a or 37b engaging with latch cam 38. Thus the shade sheet 160 can be permitted to roll all the way up, or stop at any position therebelow, as desired.

This operation has been well known for years. It is set forth better to accentuate the object of the applicant in providing the pivot arms 26a, 26b, as pivotally mounted on the inwardly extending angle legs of the respective shade mounting brackets 24a, 24b, within the cowl 10.

As shown in FIG. 4, the hinged cover has been raised and the respective left and right latching means 30a, 30b, have been urged upwardly from their latching positions shown in dotted lines, thus freeing the respective pivot arms 26a, 26b, to be pivoted downwardly about their

respective pivots

26c, 26d, on the upstanding or extending legs'of the respective shade mounting angles 25. This movement has disposed the slot 27a in the pivot arm 26a to be disposed in downwardly opening position so that the lug 28, together with the shade 16 at this end of the cowl 10 may drop downwardly, whereby the conventional pin, not shown, on the opposite end of the shade rod 29, may disengage from within the bore 27b in the pivot arm 26b by some slight leftward movement of the shade 16, and thus the shade 16 may be removed from its mounted position within the cowl 10.

Conversely, a shade 16 may be installed by first inserting the right end shade rod pin, not shown, into the bore 27b of the pivot arm 26b, and them moving the left end shade rod lug 28 up into the slot 27a in the left pivot arm 26a. Then the shade 16 may be urged upwardly to pivot the pivot arms 26a, 26b, into upper position as shown in FIG. 3, and the left and right latching means 30a, 30b, may be manipulated downwardly to releasably latch the shade 16 into operative position within the cowl 10. With the hinged cover 15 now closed, only any desired part of the shade sheet 16a may be visible at any desired time, and when the window panes 17 are not to be occluded, the complete shade 16 may be covered within the cowl 10, with the minimum exception of the pull ring 21 and a portion of the pull string 21a thereabove.

The invention symmetrically locates shade 16 with relation to curtains 23a, 23b, by the inclusion of the curtain rod hangers 19 on either side closure 13a, 13b. Thus both curtains and shade may be mounted symmetrically with relation to structure, as a window frame 18. In this regard, all an interior decorator or carpenter has to do is locate where two holes are to be made in the structural element in elevation, and in lateral relationship to the aforesaid structural element, and thus install screws 39, FIG. 4, through properly located holes therefor, as holes 40, FIG. 4 and FIG. 5, provided symmetrically within the cow] back plate 11.

The construction of the cowl 10, as shown in FIGS. 3 and 4, is such that the back pate 11, cowl member 14, and cowl side closures 13a, 1312, may all be blanked from a single sheet of metal, as aluminum or say, thin sheet or stainless steel. Also other metal may be used, as the demands of appearance and service may dictate.

The configuration of the cowl side closures 13a, 13b, exemplify differences in configuration between FIGS. 3 and 4, and various cowl side closure configurations can determine the volumetric shape of its interior. Notable the upper part of the cowl side closure inner surface is defined in FIG. 3 by convex curvature, while the upper part in FIG. 4 is defined by a straight, diagonal line divergence from the top of the back plate, followed by a part of convex curvature. In each example the lower part convergence to the proximity of the back plate is defined by concave curvature. In either case the curvature of the central and lower parts of the cowl side closures determined the curvature of the hinged cover 15. Compare the disclosure of the FIG. 3 hinge cover with the disclosure of the FIG. 4 hinge cover.

The form of curtain rod end brackets 19 is not described in detail, as curtain rod ends are of various construction, and suitable brackets 19 may be installed on the outer faces of the cow] side closures 13a, 13b, as practice may demand. Also shades 16 employed may be of various widths, thus to dictate the length of the cowl 10. The structures shown are thus not by way of limitation, but by way of suggestions of manner in which the problems solved by this invention are accomplished.

Thus the invention is not limited by the structural illustrations of solutions that fall within the broad spirit thereof, wile the appended claims are by way of example, and not by way of limitation.
