DESCRIPTION:
BRIEF SUMMARY
The invention relates to a window curtain hanging device for use with curtain rods that are round, oval, or square, that perform the function of curtain poles on which rings conventionally slide, and referred to below simply as "rods".
U.S. Pat. No. 2,988,314 describes a plastics material element including a fastener for fastening to a curtain. That element has a section that is I-shaped, requiring its ends to be clipped together to provide "straps" that are rigid and parallel to each other in use.
A practice that is becoming more widespread for securing curtains to a rod consists in replacing conventional rings by tabs made of cloth that is similar to or matches that of the curtains. Such tabs are constituted by strips of cloth of greater or lesser width, and folded over to form a loop with the open end being sewn to the curtain, or including means for engaging a hook which is either mounted on a curtain-pleating tape secured to the curtain, or else is sewn directly to the top of the curtain. Such fastening nevertheless suffers from at least two drawbacks, one associated with the tabs being fastened to one side of the top of the curtain, thereby causing the top of the curtain to tilt slightly forwards or backwards, in particular when the curtain is an interlined curtain of heavy cloth. However, the more important drawback lies in the fact that the tabs slide poorly on rods when the curtain is drawn.
The invention solves the problem by providing a window curtain hanging device constituted by a strip of plastics material whose two ends are fixed to the top of the curtain and whose central portion matches the shape of a curtain rod, the strip serving as a support for a decorative tab.
In a first variant, the strip is constituted by two flexible straps of plastics material extending from opposite ends of a curved element of rigid plastics material, provided with tab-retaining means for retaining a decorative tab. The curved element of rigid plastics material slides well on a curtain rod regardless of whether it is round, square, or oval, and it makes the curtains easier to draw than when using a tab on its own.
The stiffness of the curved element may be obtained by using a greater thickness of the same plastics material as is used for the flexible straps, or by having stiffening ribs--e.g. a central rib and two lateral ribs, or a plurality of regularly spaced-apart ribs--, or by using a stiffer plastics material for the curved element. For cost reasons, the preferred solution consists in using stiffening ribs.
Advantageously, the device of the invention includes a fastener for fastening directly to the curtain, and preferably such a fastener enables the curtain to be placed between the two flexible straps of the device of the invention. Various methods of fastening can be envisaged when the tab and the device of the invention are fastened to one side only of the curtain, and in particular, in this case, it is possible to use clips with two hooks co-operating with hook-engaging means formed on the tabs and on the device of the invention.
When the curtain is placed between the two flexible straps, it is possible to envisage providing the free end of each strap with a male pushbutton element that is inwardly directed and to sew female pushbutton elements at appropriate locations on the top of the curtain. A particularly preferred device consists in using two flat-headed pins, one of which is hollow and houses the other, the two pins being secured to each other by snap-fastening or by screw engagement. One of the pins is passed through a hole formed in the bottom portion of one of the straps while the other pin is passed through a hole formed in the free end of the other strap, and they are united after passing through an orifice formed in the top of the curtain, which orifice is advantageously implemented in the form of an eyelet.
In order to prevent the decorative tab from sliding over the device of the invention, the top portion of the curved element is provided with tab-retaining elements, advantageously cons
