6 Claims. (Cl. 211105.1)

' The present invention relates to house and store appurtenances, particularly to curtains, shades and other window adornment.

The work of hanging curtains or shades is tedious, particularly where the windows are many, as in stores, and sometimes hazardous as when the windows are high and require the use of a stepladder. In certain types of window frame coverings such as the so-called cornice structures which support heavy drapes, as well as the curtains and shades, the weight of the assembly is often considerable, requiring strong fasteners at the outer window frame andexpert deftness in mountin the members.

The primary object of my invention is to provide apparatus for mounting or hanging curtains, shades, drapes, Venetian blinds and cornice assemblies which, excepting the original job of initially securing the fasteners to the frame, does not require stepladders or other hazardous appliances. v,

Another object is to provide an apparatus for hanging curtains, shades, etc; which willpermit ready access to all parts of the curtain or'shade for inspection, repair, cleaning or replacement and does not require the'mounting of any temporary platform,-stepladder or the like. 7 a

Still another object is to provide an apparatus for supporting heavy curtains, shades, drapes, etc. in such a way that they can be released from their window frame supports while the operator stands on the floor.

Another object is to provide detachably mounting a curtain, shade or other window adornment and in l which the height of the curtain or shade can be adjusted at will with out disturbing the fasteners or other supports.

Still another object is to provide an apparatus for detachably and adjustably mounting curtains,

shades, drapes, etc., separately or as an assemblage, on fixtures in a window outer casing, and

an apparatus for in which the detaching or adjusting features can v be accomplished without the operator or workman having to elevate himself from "the floorto the level of the curtain and shadeassemblage.

A further objectis to provide a hoisting apparatus of relatively miniature size for curtains.

shades, etc. and utilizing an operating cord or a rigid rod for elevating or lowering the curtainor shade as a whole.

-A final object is to provide an apparatusfor elevating or lowering curtains, shades, drapes, etc. by use of a pulley and cord and in which the curtain and drape rod and the shade are maintained in their elevated position without 2 any continuous pull on the cord by which these elements were raised.

The invention will be better understood when reference is made to the following description and the accompanying drawings in which:

Figure 1 represents a perspective view of apparatus for raising curtains, shades, etc, improved in accordance with one aspect of my invention;

Figure 2 is an enlarged perspective view of one form that the curtain and shade elevating mechanism may take, together with a locking device for maintaining the elevated position of the curtain rod without causing stretch of the hoisting cable or cord;

Figure 3 is an elevational view of the elevating mechanism, somewhat smaller than Figure 2, and looking from the right toward the right side of Figure 2;

Figure l is a perspective View of another form of curtain and shade mounting apparatus contemplated by my invention;

Figure 5 represents the application of the invention to an assembly of curtain, shade and drape elements and showing the facility with which these heavy elements can be arranged, while standing on the floor, and then hoisted to any desired position while maintaining a predetermined arrangement between the elements;

Figure 6 is an end view of one of the details of the elements shown in Figure 5.

Referring more particularly to Figure 1, referencecharacter l designates the upper portion of an outer window frame or casement containing the usual window sash 2 and the window pane- 3. These windows are illustrated as being of the vertically slidable type as indicated by the horizontal ledge 4. In order to properly curtain a window of this type or to provide shades, it is customary to afiix fasteners either on the uppermost horizontal frame member or else on the inside upper edges of the vertical frame members so as to receive the curtain rod or the stems of the shade. Whenever it is desired to clean the curtains or perhaps to renew the shades, a stepladder is normally employed and the housewife or workman has to mount the stepladder, which in the case of a tall window, may place them in a precarious position. Just the simple task of stepping up and down the ladder, of itself, is tedious work, particularly when a large number of windows must be serviced as in the case of certain types of stores and factories. Moreover, in the case of house curtains which must be neatly arranged on the curtain rod and the frills above the rod uniformly spread, it is a well known fact that even though the curtains have been properly positioned on the rod before being affixed in its elevated position, the neat appearance of the curtain and frills is often spoiled during the act of raising the curtain rod to its elevated position on the outer window frame.

In accordance with one aspect of my invention, I provide a hoisting structure which permits the curtain rod to be threaded through the loops of the curtains and the pleats or frills properly arranged and then the curtain rod is elevated to the desired height without causing any disarrangement of the curtains on the rods. Thehoisting mechanism is shown more clearly in Figures 2 and 3 and may consist of a bracket 5 which can be screwed as indicated at 6 to the upper horizontal member of the outer window frame. The strap or bracket 5 is provided at the left hand end (as seen in Fig. 2) with a transversely extending portion 36 (shown in Figure 1) in which is fixedly mounted a stub shaft 1. A pulley 8 is adapted to rotate on this shaft, one of the flanges of the pulley having preferably a circular periphery 9, .and the other having a notched periphery as indicated at I0.

Theinner or working surface of the pulley may be formed by tapering sides and having a curvilinear groove at the bottom in order to receive and pinch a cord I l which extends over the pulley. The pulley 8 is restrained from sliding off the shaft 1 in any suitable manner, for example by the use of a cotter pin I2 extending through an openingiin the shaft. The purpose of the notches I0, will be set forth hereinafter. The cord II is attached loosely to receive a metal ring I3 having a curvilinear shape at the outer periphery in order to provide considerable metal thickness at a position about midway of the length of the ring. A countersunk opening indicated at I4, of any desired depth, is provided atone side of the ring, at the exterior surface, this opening being adapted slidably to receive a rod I5 which may constitute an extension of. a curtain rod I6. The latter is preferably; of a square, tubular shape and is adapted telescopically to receive a square rod of solid section I! which telescopes into the tubing I6 so as to effect different lengths as is customary with regard to curtain rods. The rod I! terminates at the right-hand end (referring to Fig. 2)

in the round rod I5 similar to that described hereinbefore and the latter is swivelly received by a ring; I3 through which a cord or cable II is hrea d In order to position the rings I3 with respect to thecord II, knots I8 are provided in each of the cords. at the proper heights so that the rod elements I6, I! remain substantially horizontal.

The cords or cable IIare preferably of the endless type, i. -e.' form loops, and as stated hereinbefore,

the upper portions lie within the V-sliaped grooves formed between theflanges 9 and I of the pulley 8. 7 v

In operationthe curtain rod elements I6, I1 are threaded in the usual manner through the hand loops ofithe curtains, this operation being .done while the housewife or workman stands on the floorfand the rod has been lowered to a convenient'position. When the curtain or curtains have been properly spread along the'rod elements, the far side lengths of the cord or cable II are pulled downwardly to cause the curtains to be raised. As the circular portions I of the rod approach the curved notches of the pulley flange l0, the jnearest notch will receive the respective rods I 5 and as each pulley continues to turn, the circular portions I5 will become more elevated until the curtain rod has reached the proper height. At this time any suitable and well known mechanism could be employed for holding the pulley 8 in its instantaneous rotated position, such mechanism being usually operated by swinging the descending cord length to one side or the other of the vertical axis of the pulley 8. In the event that a locking device on the pulley is not desired, suitable catches or grips may be provided on either length of the cord or cable to prevent any further movement thereof and therefore serving to hold the curtain rod in its desired uppermost position. However, in accordance with another featur of my invention, there is provided a mechanism which restrains the curtain rod from dropping unless deliberately lowered, this mechanism operating on a principle which does not involve a cord gripping or a pulley locking device. llt employs the principle of causing the curtainrod by its own weight to rest against a stationary projection and the latter prevents the rod from dropping. Thus, inFigure 2 there is a projection I9 extending at right angles to the strap 5, parallel to the inner flange of the pulley but spaced therefrom a sufficient distance in order to receive the rod I5 as the latter is caused to move, first upwardly and then around the back of the pulley 'by continual pulling of the far side of the cord I I.

This position of each rod extension I5 is shown in Figure 3 and it is obvious that since the entire curtain rod is to the side of the vertical axis of the pulley opposite from the side overwhich it rods over the front edge of the pulley to be lowered;

to any desired height. It is obvious that the distance between the flanges of the pulley can readily accommodate the knots I8. I V

A swivel action is obtained between the ring I3 and each rod I5 at the opening I4, which tends to prevent the curtain rod elements I6, I! from rotating so that even though the rod I5 does move in a transverse direction along the top of the pulley 8 and then in a slight downward direction at the rear side of the pulley until'it con:

tacts the upper, edge of the projection I9, little or no movement of the rods I6, I! out of the vertical line will be noticed. The curtain therefore remains upright.

It is apparent that when the pulley is either 3 locked in any suitable and well known manner as explained hereinbefore, or when the curtain rodis caused to rest on the upper edges of the projec tions {thin accordance with one of the features of my invention, any tendency for the cable or .cord II tostretch is avoided. This prevents undue wear in the cord. The loop lengths of the cord are preferably such that the lower loops extend not much below the middle sash of the double ft are vertically mounted along the sideouter frame members of the window, suitablefittings 22 being employed for this purpose. These rods may be formed of tubular material to reduce expense. The curtain rods are of any suitable telescopic type as indicated at 23 and one of the curtain lengths terminates in an eyelet '24 which is slidably received by the vertical guide M3. The other rod element is provided with a tubular element 25 which extends at right angles to the curtain rod and is slidably received by the vertical guide 2i. A locking catch 26 of any well known and suit able type is secured to the member 25, this catch also serving the purpose of a handle in moving the tubular member, andtherefore the rods 23, in the vertical direction.

In operation the rods 23 arethreaded through the hemmed loops of the curtains and in order to elevate the curtain in its preearranged condition, itis simply necessary to loosen the catchZG and to move the curtain on its rod to any desired height. In practice, the extension 25 would be so long in the vertical direction that the rods 23 can be moved to their most elevated positionwhile the operator or housewife is still standing on the floor. Thus, as in the case of the structure described in Figures 1 to 3, there is no necessity for using a stepladder or other elevated platform for affixing the curtains in their uppermost position except when the upper fixtures '22 are being screwed into the frame.

While I have described the structures in Figures 2 and 4 as being most applicable to the use of curtain rods, it is obvious that shades could also be hoisted in the same manner by merely terminating the pins of the shade either in rings I3 for encircling a cord I I or a vertical guide I '2, and in addition, by providing a tubular member 25 in case the rigid form of elevating mechanism is desired.

It is further obvious that drapes can also be hoisted in the same manner by using the flexible cord-pulley mechanism in Figure 2 or the slidable ring arrangement of Figure 4..

In case it is desired to hoist a combined curtain and shade combination, a structure such as shown in Figures 5 and 6 can be employed. A bar or plate 2'! is provided to which is affixed the usual shade brackets 28 and the usual curtain rod fixtures 29. The curtain rods may be of the telescopic strip brass type having a U-shape indicated at 30 so as to extend out beyond the shade CH. The plate 2'! may be screwed as indicated at 32 to the threaded openings at 33 of the rod shown in Figure 2. Thus the window shade and the cur tains can be arranged in their respective positions and then lifted t their proper elevated position by pulling down on the far lengths of the cord I I of Figure 2 in the same manner as was explained with respect to the curtain rods I6, I1.

In order to assure that the bar or plate 21 will remain vertical and thus prevent any tilting effect of the curtains, a pair of metal skids 34 may be screwed as indicated at 35 to the rear side of the bar at the upper edge so as to maintain the proper distance between the upper surfaceof the bar and the surface of the outer window frame when rods I6, I1 are at their most elevated position and the rods I5 are resting on the projection I 9. Thus the bar 2! remains in substantially the same position when both elevated and lowered and no disarrangement of the curtains is caused.

It is obvious that the bar or plate 21 provides a suitable carrier not only for shade and curtain rods which are fixedly mounted in place, but also for cornice structures which usually involve heavy drapes covering the curtains. All of these elements can be properly positioned while the workman remains standing on the floor andthe entire assembly will have the same relative posi tions when the structure is elevated as explained hereinbefore. I

It may also be desired to mount a Venetian blind on the plate 21 and hoist the same by the use of the cord II or by the rigid form of hoisting mechanism shown in Figure 4. This is particularly desirable as it permits ready cleaning of the upper parts of the Venetian blind which can be lowered to a standing position and theseparts are normally accessible only by-the use of a stepladder.. l

It will be understood that various modifications and arrangements in structure could be made without departing from the spirit of my inven: tion and, accordingly, I desire to comprehend such modifications and substitutionsof equivalents as may be considered to come Within the scope of the appended claims. 3
