Abstract
Apparatus for attaching a cable for hanging curtains to a bracket mounted on a wall and for tensioning the cable, has a clamp mountable on the bracket and a receiver for capturing an end of the cable. The clamp and receiver can be screwed together to secure the cable to the bracket while tensioning the cable. For long curtain spans, a clamp may be mounted on an intermediate bracket with two receivers attached to and extending from the clamp in opposite directions for supporting two cables in alignment.
Description
- The present invention relates to apparatus, for hanging curtains in front of a wall or window, including a cable from which the curtains may be hung, either directly or by means of rings, hooks, clips or other known curtain fasteners. More specifically, the invention provides for hanging a supplemental set of curtains on a cable supported on conventional brackets which are used to mount a conventional curtain rod in front of a wall or window.
- It is known in the art to hang curtains in front of a wall or window by means of a rigid or telescoping rod mounted on brackets which are screwed to and extend outwardly from the surface of a wall above the area to be covered by the curtains. It is also known to hang more than one set of curtains, each with its own curtain rod, by supporting the rods in parallel spaced relationship on a common set of brackets which are screwed to and extend outwardly from the surface of a wall above the area to be covered by the curtains.
- The use of a cable as a substitute for a rigid or telescoping rod for hanging curtains has recently become popular. There are different requirements for supporting curtains on a flexible cable, which must be tensioned to prevent sagging under the weight of the curtains, versus the use of a rigid or telescoping rod which need only be supported at its ends, and possibly at one or more intermediate points in the case of very long rods.
- Until the present invention, when two sets of curtains were to be hung, one in front of the other, and one set was to be suspended from a rigid or telescoping rod while the other set was to be suspended from a flexible cable, separate sets of brackets were required, i.e., cable brackets and rod brackets. This required drilling the wall in separate locations for each set of brackets.
- In addition to the damage which is done to the walls, and the cost of the additional brackets, there are further disadvantages to the necessity for two sets of brackets. The elevations of each set of curtains, not only with respect to the adjacent window, floor or ceiling, but also with respect to each other, can be critical to achieving an aesthetically pleasing appearance. Also, multiple sets of brackets, particularly in crowded installations, can interfere with one another.
- The present invention overcomes the aforementioned shortcomings of prior art curtain cable mounting systems in providing an adapter mountable on a conventional curtain rod bracket for tautly supporting a cable whereby a first set of curtains can be mounted on a rigid or telescoping rod supported by a pair of brackets and a second set of curtains can hung from a cable connected to adapters which are, in turn, respectively mounted on the brackets.
- In a first embodiment of the invention, suitable for use with cylindrical curtain rod support brackets, each adapter is in the form of a closed ring having a cylindrical opening substantially congruent to a cross section of the curtain rod bracket transverse to the axis of the bracket. Each adapter used to support an end of a cable has a single screw projecting radially from its outer circumference for receiving a cable retainer having a threaded cylindrical bore complementary to the threads on the screw of the adapter, the cable retainer further having a narrower bore for snugly receiving an end of the cable which is secured to the cable retainer by one or more set screws.
- For curtains having a long enough span to require an intermediate bracket for supporting a correspondingly long curtain rod (or the ends of two or more curtain rods coaxially mounted end-to-end) an adapter is provided in the form of a closed ring with two screws projecting in diametrically opposite directions from the outer circumference of the ring. Each screw can receive a cable retainer as described above. That is, two cables can be supported end-to-end, with their innermost ends secured in respective cable retainers that can be threaded onto the oppositely projecting screws of a single ring adapter.
- In a further embodiment of the invention, the rings from which the adapters are formed can be tapered so that two such rings, each with only one projecting screw, can be mounted on a common intermediate bracket side-by-side with their respective screws projecting in diametrically opposite directions while maintaining coaxial alignment. In this way two or more cables may be mounted end-to-end and in alignment. A single adapter design can suffice for use singly at either end of the curtain span and, in pairs, at each intermediate support bracket.
- The apparatus of the invention is not limited to brackets having cylindrical members. In still another embodiment of the invention, instead of a circular ring, the adapter is in the form of a squared off or rectangular C-clamp for mounting on a conventional right angle wall bracket. For use at the end of a curtain span, one of two parallel legs of each C-clamp is provided with a transversely outwardly projecting screw for receiving a cable retainer as described above. For use on an intermediately placed bracket, each of the two parallel legs of each C-clamp can be provided with a transversely outwardly projecting screw, the oppositely pointing screws being in coaxial alignment for supporting two respective cables end-to-end and in mutual alignment.
- Finally, as in the case of the circular ring adapters described above, each C-clamp having a single screw can have a tapered width whereby two such C-clamps, each with only one projecting screw, can be mounted side-by-side on a common intermediate bracket with their respective screws projecting in diametrically opposite directions while maintaining coaxial alignment in order to enable two or more cables to be mounted end-to-end in mutual alignment. A single C-clamp adapter design can suffice for use at either end of the curtain span, and, by doubling up into pairs, at each intermediate flat support bracket.

FIG. 1 of the drawings, there is shown a prior art cable support system for curtains having a cable 1 each end of which is clamped within a holder 3 mounted on a base 5. The bases 5 are, in turn, affixed to parallel facingwall surfaces 7, for example, by a screw passed through the a center opening in each base (not shown). - Referring now to
FIGS. 2 a and 2 b, in another prior art cable support system for curtains, for use in environments where the use of facing walls for supporting cable brackets is not feasible, end brackets 11 are mounted on a wall in front of which the curtains are to be hung. Each bracket 11 has abase 13, aspacer 15 and aholder 17 for acable 9. For long curtain spans, acentral bracket 12 may be used to support an intermediate portion of thecable 9. - The prior art cable mounting systems shown in
FIGS. 1 and 2 a,b must be used independently of, and in addition to, any other brackets which may be present for supporting a conventional rigid or telescoping curtain rod. - Turning now to
FIG. 3 of the drawings, there is shown a cable support system in accordance with a first preferred embodiment of the invention. Two conventionalcylindrical brackets 21 are mounted on a wall 23 for supporting a rigid ortelescoping curtain rod 25 as is known in the art. Circumscribing eachbracket 21 is a clamp in the form of acircular ring adapter 26 as illustrated inFIGS. 4 a,b and 5 a,b. Connected to each ring adapter is a receiver in the form of acable retainer 27, best seen inFIGS. 6 a-c, which is secured to an end of the cable 29. - Referring now to
FIGS. 4 a,b-5 a,b, eachring adapter 26 is in the generally shape of the locus of a rectangle spaced from and rotated about a parallel axis through the center of the ring. Extending from the outer circumference of eachring adapter 26 in a radial direction is a clamp connector in the form of ascrew 31. - Turning now to
FIGS. 6 a-c, eachcable retainer 27 is in the shape of a hollow stepped cylinder as seen inFIG. 6 a. Thecable retainer 27 has anarrow length 30 running inwardly from one end with an outer diameter and inner diameter less than the respective outer diameter and inner diameter of the remainingwider length 32 which runs inwardly from the opposite end of the cable retainer. Thenarrow length 30 andwider length 32 are connected at a slopedcircular region 34 of the exterior of thecable retainer 27. - A receiver connector in the form of a
hollow bore 36 in the wider length of the body of thecable retainer 27 has a diameter and is threaded complementary to the diameter and thread of thescrew 31 on theadapter 26 whereby the cable retainer can be threaded onto thescrew 31 for being affixed to theadapter 26 and the bracket 11 on which theadapter 26 is mounted. - The
narrow length 30 of thecable retainer 27 has anaxial bore 38 with a diameter only slightly greater than the diameter of thecable 9 for enabling an end of thecable 9 to be snugly received therewithin. Two setscrews 40 threaded into apertures penetrating the full thickness of the circular wall of thenarrow length 30 of thecable retainer 27 can be tightened to secure an end of thecable 9 within thecable retainer 27. - In accordance with the preferred embodiment of the invention, the
narrow length 30 of thecable retainer 27, proximate the slopedcircular region 34 of thecable retainer 27 is provided with diametricallyopposite holes 42 which fully penetrate the circular wall of the narrow length of thecable retainer 27. AnAllen wrench 45 sized to fit theset screws 40 can be passed through theholes 42 thereby enabling the Allen wrench to be used as a lever for rotating either or bothcable retainers 27 to tension the attached cable by threading eachcable retainer 27 further onto itsrespective screw 31 as shown inFIG. 7 . - In order to minimize twisting of the cable during tightening of the
cable retainers 27, thecable 9 may be pretwisted before attachment of its ends to itscable retainers 27 in a direction such that as the cable retainers 33 are tightened onto thescrews 31, thecable 9 will untwist. Alternatively, thescrew 31 on an adapter used to secure one end of a cable can be provided with a thread opposite in direction to the thread on theadapter screw 31 used to secure the opposite end of the cable. With this type of arrangement, the retainers can be rotated, one clockwise and the other counterclockwise, for tensioning the cable without twisting the cable. - In use, the cable(s) 9 can be passed through a channel sewn into a curtain rod before being screwed onto the
adapters 26. Alternatively, curtain rings or hooks may be passed over the ends of and onto the cable. - Referring now to
FIG. 8 , where curtains having a long span are to be hung, and an intermediate bracket 51 is wall mounted intermediate end brackets 11, anadapter 52 similar to the ones shown ifFIGS. 4 a,b and 5 a,b, but having twoscrews 53 extending in diametrically opposite directions (seeFIGS. 9 a-c) can be used. - Another embodiment of the invention will now be described with reference to
FIGS. 10-13 b. Here eachadapter 61 has a tapered width. Asingle adapter 61 can be used on each end bracket 11. Two of thesame adapters 61 may be placed side-by-side on the same intermediate bracket with their respectivesingle screws 63 extending in diametrically opposite and coaxial directions as best seen inFIGS. 10 and 12 a,b. - The
adapter clamp 61 has a profile with a one side parallel to a central axis of theclamp connector screw 63 and an opposite tapered side inclined relative to the central axis ofscrew 63. The distance between the central axis of thescrew 63 andparallel side 64 of the clamp body is such as to enable two identical clamps to be placed on a single bracket with the taperedsides 66 of each clamp in abutting relationship, and said central axes of the clamp connector screws 63 in mutual alignment The average of the maximum and minimum distances betweensides side 66 is equal to the distance between the central axis of eachclamp connector screw 63 and the parallelclamp profile side 64. - The invention is not limited to circular brackets. By using an appropriately shaped adapter, a cable may be mounted on an existing conventional flat bracket extending from a wall.
- Referring now to
FIGS. 14-16 , there is shown a curtain installation with conventional rightangle wall brackets 65 including a forward projectingmember 67 having a substantially rectangular cross section with a channel for receiving aslider 69 terminating in aU-shaped holder 71 for receiving acurtain rod 73. - There is removably mounted on the
slider 69 of thebracket 65, as shown inFIG. 14 , anadapter 75 in the form of a squared off or rectangular C-clamp 61. Each of two parallel members of the C-clamp 61 has alip 77 for forming a channel 79 having a width substantially equal to the width of theslider 69. The other parallel member of the C-clamp 75 is apertured for receiving aset screw 81 that can be tightened against theslider 69 for securing the C-clamp adapter 75 to thebracket 65. - The C-
clamp 75 is shown inFIGS. 17 a and b. For use on intermediate brackets, the C-clamp 75 can have two screws projecting in opposite directions while maintaining coaxial alignment. Alternatively, each C-clamp can be tapered whereby two such C-clamps, each with a single screw can be mounted side-by-side with their screws directed in opposite directions while also maintaining coaxial alignment as shown inFIG. 18 . - It is to be appreciated that the ring and C-clamp described above, in their several forms, are two of many possible variations of adapters that can be attached to a bracket for a rigid or telescoping curtain rod, for supporting a curtain cable without departing from the spirit and scope of the invention. For example, instead of the screw being on a clamp for being threaded into a receiver, the clamp may be provided with a threaded bore in a wall of its body for receiving the threads of a screw extending from the receiver.
