NFL, a corporation of New York Filed Mar. 13, 1962, er. No. 179,397 2 tjlairns. Ci. 2llltl3) This invention relates to drapery fixtures and, more particularly, to a novel elevating and lowering accessory for conventional traverse rods, as well as to a novel combination of said accessory and traverse rod.

The ordinary means provided for hanging drapes so that they can be opened and closed is a traverse rod. Such rods usually are mounted on a ceiling or wall considerably above the reach of an average person, and to secure drapes thereto or remove them therefrom, it is necessary to climb upon a ladder, chair or similar means in order to reach the connections (drapery hooks or the like) between the drapes and the rod. This arrangement constitutes a recurrent inconvenience since it is necessary from time to time to take down the drapes for cleaning, adjustment or other reasons. And, of course, when it is desired to put them back up, the user must again climb up to reach the traverse rod. Climbing up to reach the traverse rod for the foregoing purposes is not only highly inconvenient, it is also dangerous and a common cause of household accidents. This is particularly so because in many cases the drapes are quite heavy so that it is difficult for the average user to hold and attach them to the rod and maintain his balance while standing on a ladder or the like.

Accordingly the provision of a means permitting a person to reach the traverse rod without having to climb in order to do so would be highly useful and desirable.

It is a principal object of the present invention to provide an elevating and lowering accessory for a traverse rod and a combination of such accessory and a traverse rod whereby the rod can be easily and conveniently manually lowered from its elevated place on a wall or ceiling to any desired lower level within the reach of. a user by a simple operation performed by the user while standing at floor level.

It is another object of the present invention to provide an accessory of the character described which can be used with conventional traverse rods by means of a simple and inexpensive modification thereof.

It is another object of the present invention to provide an accessory of the character described which can be manufactured in several sizes each of which is adaptable to be used with many different sizes of conventional traverse rods.

It is another object of the present invention to provide an accessory of the character described from which the associated traverse rod can be simply and easily manually unlocked from floor level in order to permit the traverse rod to be lowered.

It is another object of the present invention to provide an accessory of the character described which does not require any modifications to the wall or ceiling for use.

It is another object of the present invention to provide an accessory of the character described which can be easily assembled, installed and used by an unskilled consumer without the application of any appreciable mechanical skill.

It is another object of the present invention to provide an accessory oi the character described which can be simply and inexpensively mass produced.

It is another object of the present invention to provide an accessory of the character described which is rugged, durable and unobtrusive in appearance.

Other objects or" the invention in part will be obvious and in part will be pointed out hereinafter.

The invention accordingly consists in the features of construction, combinations of elements, and arrangements of parts which will be exemplified in the device hereinafter described, and of which the scope of appli cation will be indicated in the appended claims.

In the accompanying drawings, in which is shown one of the various possible embodiments of the invention,

FIG. 7 is a plan view showing a detail of the locking and centering pin.

Generally, the objects of the invention are carried out by providing an accessory which is permanently mounted on a wall or ceiling and which includes means cooperating with associated means provided pursuant to the present invention on a traverse rod for raising and lowering the latter between an extreme upper position at which the rod is above the users reach and a lower position within the users reach. The invention also includes the provision of means for automatically, manually-unlockably, locking and horizontally leveling the traverse rod and centering the same lengthwise and laterally in the extreme raised position thereof while holding the same against lengthwise, lateral and twisting movement. Still further, the invention includes provision for manually unlocking the traverse rod from its extreme upper position, said unlocking being carried out by a user standing at fioor level.

The raising and the lowering of the traverse rod is achieved by pulleys on the accessory which cooperate with pulleys provided on the traverse rod. The locking-leveling-centering-holding operation and the manual unlocking are accomplished by cooperating means secured to the accessory and the traverse rod.

Referring now in detail to the drawings, the reference numeral iii denotes an elevating and lowering accessory of the character described fabricated from a strong light material such, for example, as sheet iron or aluminum. The accessory is used in combination with a traverse rod 12, also made of metal, which is conventional except for the added members to be pointed out hereinafter.

The accessory is an elongated object which includes a first angle iron 14 in which a second angle iron 16 is telescopically (extensibly) received. Angle iron 14 comprises a front vertical web 18 and a horizontal web Ed, said webs respectively terminating in retroverted bends 22, 24 at the free edges thereof. The corresponding free edges 2d, 28 of the vertical and horizontal webs 34D, 32 of angle 16 are slidably receivable in said bends with the associated webs of the angle irons juxtaposed.

The accessory may be secured to a wall or ceiling in any conventional manner, as by brackets, screws, nails, toggle bolts or the like. These are not illustrated in the drawings.

The accessory is provided with pulleys 34 and 36 near the left end thereof as viewed in FIG. 1 and a pulley 33 arouses near the right end thereof. The block of pulley 34 has three sheaves, 34a, and Zia-c, the block of pulley 36 has two sheaves, 36a and 36b, and the block of pulley 38 has one sheave, 38a. Said pulleys are made of any suitable material such, for example, as plastic or metal; the pulley blocks are secured in any conventional manner, as by screws, to the undersurface of the horizontal webs of the accessory, the blocks of pulleys 3d and 36 being secured to web 32 and the block of pulley 355 being secured to web 29. The pulley sheaves are mounted to rotate about parallel horizontal axes, said axes being perpendicular to the longitudinal axis of the accessory.

The traverse rod 12 is an elongated object including end caps and a conventional draw mechanism for opening and closing drapes hung therefrom. The latter mechanism is not shown except for draw cords 44 illustrated in FIG. 1 and one of the carriers for the drapes which is shown in FIG. 3 and denoted by the reference numeral 42. Drapes 46 are illustrated attached to the traverse rod.

Pursuant to the present invention, a conventional traverse rod is additionally provided with single pulleys 5t) located on the top surface of the rod a short distance in from each end, pulley 43 being on the left and pulley 5% on the right as viewed in FlG. 1. The sheaves of said pulleys are journalled in blocks to rotate about parallel horizontal axes which are perpendicular to the longitudinal axis of the rod. The traverse rod is elevated and lowered by draw cords 52a and 521) which are threaded through the aforesaid pulleys of the accessory and traverse rod in a conventional manner. The threading set up is best seen in FIG. 1. An end of cord 52a is secured in an anchoring bracket 54 attached, as by rivets, to the undersurfaee of the horizontal web 26 of angle iron 1 2- between pulley 38 and the adjacent right end of said angle iron. The cord is trained under the heave of pulley 50 on the traverse rod, then over the sheave of pulley 38 of the accessory, next over one sheave (36a) of pulley 36, then over one sheave (34a) of pulley 34, and finally hangs down toward the floor; the cord is long enough to be within the reach of a user when the rod is in lowered position. The aforesaid sheaves are aligned to facilitate proper tracking of the cord. An end of cord 52b is secured to an anchoring bracket 56 attached, as by rivets, to the undersurface of the horizontal web 32 of ang e iron 16 near and to the right of pulley 36 as viewed in HQ. 1. Cord 52b is trained under the sheave of pulley 43, over the other sheave (36b) of pulley 36, over a second sheave (34b) of pulley 34 and then hangs down in the same maner as cord 52a. Cords 52a and 52b preferably are cross connected, e.g. by being tied together, at a point remote from the accessory while the traverse rod is in longitudinal position so as to assure level raising and lowering of the same. Additionally, the distances between bracket 54 and pulley 38, and bracket 56 and pulley 36, are substantially equal, also to facilitate horizontal orientation of the traverse rod during raising and lowering thereof.

Pursuant to the instant invention, cooperating means are provided on the traverse rod and the accessory for automatically, mariually-unlockably locking the traverse rod to the accessory at the extreme upper position of the rod, while at the same time horizontally leveling the rod and centering the rod lengthwise and laterally in the locked position and holding the same against lengthwise, lateral and twisting movement. The aforesaid means comprises at least two spaced pilot locks; two such locks are shown in the drawings, one being located a short distance in from the left ends of the accessory and traverse rod and the other a short distance in from the right ends thereof, as viewed in FIG. 1.

Each pilot lock comprises a male half 62 disposed on the traverse rod and a female half 64 located on the accessory. The male half 62 comprises an upwardly taperin pin (plug) 66 (see FIGS. 3 and 7) which may be die cast or molded. The pin includes an attaching flange 68 at the bottom and front thereof, the inner contour of said flange being provided with a hook that is adapted to receive the conventional longitudinal, forwardly facing protrusion 7t) at the front of the traverse rod adjacent the top thereof. By forward, front or the like is meant the side of the accessory or rod facing into a room, and by rearward, back or the like is meant the side facing the wall. The pin 66 is provided with a clamp 72 secured to the back surface thereof by a headed screw 74 the shank of which passes through an opening in the clamp and is threadably received in a tapped opening in said back surface. The clamp includes a concave lower tip 76 the inner contour of whi h is adapted to receive a horizontal protrusion 78 on tne traverse rod corresponding to protrusion 76? but located at the back of the traverse rod adjacent the top thereof. The pin is detachably but firmly secured on the top of the traverse rod by means of flange 68 and clamp 72.

The exact shape of the pins is not critical, but they must be upwardl tapered. In the embodiment illustrated, the rear surfaces of the pins are flat and vertical and the pins taper rearwardly as well as upwardly so as to have curved front faces tapering into curved tops. in other words, each pin is in the shape of an upwardly converging cone with a rounded apex and with a segment of the rear thereof truncated by a vertical plane. Each pin is provided with an elongated blind opening fit in the left side thereof as viewed from the rear, the longitudinal axis of each said opening being parallel to the longitudinal axis of the traverse rod.

The female half of each pilot lock constitutes an element such as a rectanguloid block 82 secured, as by rivets or nuts and bolts, to the undersurface of the horizontal web of a different angle iron. Each block 82 includes a downwardly facing well 84 the inner contour of which is tapered rearwardly and upwardly and is adapted to slidably and matchingly receive the conical shape of the associated pilot pin. The blocks and pilot pins are so disposed on the accessory and traverse rod, respectively, that each well is matchingly aligned with the associated pilot pin. As a result of the aforedescribed construction of the wells and pilot pins and the location thereof with respect to one another, the pilot pins will be camrned into the associated wells when the traverse rod is raised sufijciently towards its extreme upper position, and after full entry of the pins into the wells the rod will be centered lengthwise and laterally with respect to the accessory and, furthermore, will be leveled (assuming that the angle irons are leveled). Moreover, after such entry, lengthwise, lateral and twisting movement of the rod with respect to the accessory will also be prevented because of the presence of at least two locks and the matching engagements of the two halves of each thereof.

To detachably retain the halves of the locks in engagement with one another, each pilot lock includes a springloaded latch 36 mounted in a block 82. and adapted to be camrned into the blind opening Stl of the associated pilot pin 66. The latch assembly is shown in detail in FIGS. 2, 5 and 6 and will now be described. The block includes an elongated circular through horizontal opening 38 communicating with the :well $4 thereof and longitudinally coaxial with the blind opening 86 of the associated pilot pin when the latter is fully received in the well. Said opening includes a tapped mouth 9% (remote from the well) in which a threaded bushing 92. is received. A seat EM between the mouth 9% and the well is formed in opening 88. The latch is of such diameter as to pass through opening of the block and be receivable in the lind opening 3% of the pilot pin. Secured to it is a collar 96 which abuts seat 94, the collar in turn being secured to a spindle 98 projecting through bushing 92, and out of open g at the end thereof remote from the well. A h ical spring lliti is held under compression between the collar and the end of the bushing facing the collar and biasses the latch lid into the well. The end lllY-Z of the latch extending into the Well is smoothly rounded to facilitate entry into the blind opening 80 of the associated pilot pin as described hereinafter.

Each spindle is threaded at its outwardly projecting end and extends through an opening in a fiat rectangular bridle 104, said opening being coaxial with opening &8 of the block. The spindle is secured to the bridle by nuts teen and less threaded onto the spindle on opposite sides of the bridle. The position of the spindle and thus of the latch can be adjusted by means of said nuts. Each block includes an integral elongated guide pin 1% slidable in an opening 11% in the bridle; the longitudinal axes of said pin and opening are parallel to the longitudinal axis of opening 83. Said pin is of such length that even when the bridle is moved away from the block a sufficient distance for the latch 86 to be fully retracted from the well, said pin is still within the opening 116.

The bridles are biassed toward their associated blocks by the helical springs M20, so that the latches will normally be located within the wells when the pilot pins are not recevied therein. V hen the pilot pins enter the wells, the tapered sides thereof abut the rounded ends of the latches and cam the latches out of the wells until the blind openings at; of the pilot pins become aligned with the openings 88 of the associated blocks at which point the latches snap into said blind openings thereby locking the pilot pins in the walls.

The means for manually unlocking the pilot pins from the blocks operates by retraction of the latches. Said means comprises a standard wire cable 112 anchored to the bridle of one block and adjustably secured to the bridle of the other block (see FIG. 1). As shown in FIGS. 1 and 2, the cable is anchored in the bridle of the block on the right side of the drawing in the following manner: The end of the cable is attached to a threaded pin which extends through an opening in said bridle, said opening desirably being disposed on the opposite side of the spindle opening from the guide pin opening 110. The pin is held to the bridle by nuts 114a and 11 4b. The other end of the cable likewise is attached to a threaded pin that is passed through an opening in the bridle of the other block, i.e., the one on the left side, and is secured thereto by nuts 116a and 11611. A cord .118 is secured to the free end of the latter pin and extends over sheave 340 of pulley 34 and hangs down to within a users reach. By pulling on cord 118 the bridles are moved away from their associated blocks whereby the latches are retracted. In this way the pilot pins can be unlocked from the blocks. The user then lowers the traverse rod by allowing cords 52a and 52b to be pulled upwardly by the weight of said rod.

A given size of accessory can be used with various sizes of traverse rods by sliding of angle iron 16 relative to angle iron 14 prior to securement of the accessory to a wall or ceiling. The length of cable 112 will, of course, have to be adjusted to accommodate the degree of telescoping of the angle irons so that the bridles of both blocks will re retracted simultaneously away from their associated blocks and the asscoiated latches will be simultaneously retracted from the openings 80 of the associated pilot pins.

It will thus be seen that there has been provided a device which achieves the several objects of the invention and which is well adapted to meet the conditions of practical use.

As various possible embodiments might be made of the above invention, and as various changes might be made in the embodiment above set forth, it is to be understood that all matter herein set (forth or shown in the accompanying drawings is to be interpreted as illustrative and not in a limiting sense,
