Description

TECHNICAL FIELD The present invention relates to the technical sector of curtains, and relates to an element for the formation of a curtain guide for maintaining said curtain in a corrugated conformation.

PRIOR ART In recent years several systems have been developed for suspending curtains on rails or on a rod and offering a particular aesthetic appearance of undulation on either side of the rail or the rod. A first system uses slider carriages for insertion into the rail. Said carriages are connected by a rope with a greater or lesser spacing. This first system also requires the use of a ribbon, comprising a continuous row of woven pockets near the upper longitudinal edge of the curtain, and "snail-like" staples, well known to those skilled in the art, to be secured to the rail. In this first system, the length of the curtain must correspond exactly to the combination of multiple intervals between two sliding carriages and their amplitude. A second system employs a ruffling tape that replaces the formation of the regular spaces of the rope slider system and adapts to the most common models of curtain rods equipped with rings. This second system can be used both in ceiling installation and in wall installation in contrast to the first system. However, this second frowned ribbon system has the major disadvantage of requiring, at the time of sewing said frothing ribbon on the fabric, a pre-positioning thereof, so that its ends are identical and form a perfect symmetry of the folds.

Other products make it possible to adjust the amplitude of the corrugation and to correct the desired finished length, but these have the disadvantage of generally offering a half-wave and do not solve the positioning for the seam.

Still other products can solve the problem of the corrugation but do not consider the problem of the finished length and positioning for the seam. Thus, it appears that the current state of the art does not solve all the drawbacks identified and remains, by its complexity of application, reserved for professionals 10 of the manufacture of curtains. SUMMARY OF THE INVENTION Thus, the invention tends to provide an element for the formation of a curtain guide for maintaining said curtain in a corrugated conformation. An object of the invention is to provide a universal system that can be used on the various known rod supports. The invention also makes it possible to adapt to any type of curtain, whatever its width, and without requiring a preliminary mark for laying on the fabric. To solve the aforementioned problems, it has been developed an element for the formation of a curtain guide for maintaining said curtain in a corrugated conformation. According to the invention, the element is in the form of a S-shaped half-wave piece, comprising a first end comprising a male-type coupling member, and a second end comprising a coupling member. complementary type female. The first end of an element is intended to be hingedly coupled with the second end of another element so as to allow said two elements to adopt an unfolded position in which they are spaced from each other for the formation of a ripple, and a folded position in which they are brought closer to each other. The successive coupling of a plurality of elements forms the actual guide. In this way, a number of elements, to be defined according to the width of the curtain, coupled together and then secured to the upper or lower longitudinal edge of a curtain allows a guide for said curtain to be formed in order to maintain in a wavy conformation. These elements may, for example, be inserted into a hem that includes said upper or lower longitudinal edge. In another embodiment, more likely, a ribbon may be stitched to the upper or lower longitudinal edge of the curtain. This ribbon includes a series of regular pockets, along its length, allowing the installation of conventional or specific hooks to secure said ribbon on a rail or a rod for example. The ribbon also comprises a continuous tubular along its length, intended to receive by insertion a plurality of elements coupled together forming the curtain guide. Once secured, the plurality of elements form a guide for the curtain. Indeed, when the curtain is unfolded, that is to say moved in its elongation position in which it hides a window, for example, said elements are spaced apart from each other and move into their unfolded position, in which it form two by two a ripple. The plurality of elements form a plurality of waves. The curtain is thus maintained in a corrugated conformation.

Then, when the curtain is folded, that is to say mus in a shortened position in which it no longer hides the window, for example, said elements are brought closer to each other and move into their folded position in which they attend and facilitate the folding of the curtain and keep it in this position.

Preferably, the coupling members comprise a stop for the unfolded position. According to a particular embodiment of the element according to the invention, the male-type coupling member is in the form of a protruding finger, and the complementary female-type coupling member is in the form of a projecting finger. the shape of a clevis receiving said finger. The finger is pivotable in the yoke about an axis orthogonal to the plane comprising the S-shaped element.

Advantageously, the element according to the invention comprises lightening portions in the form of recesses.

Preferably, and to enable the length of the guide to be adjusted to the length of the curtain, the element according to the invention comprises a plurality of transverse hyphenation lines regularly distributed over the length of said element.

In this way, the element can be broken along a hyphenation line, in order to shorten its length and thus make it possible to adapt to the length of the curtain.

The element for the curtain guide assembly according to the invention. DETAILED DESCRIPTION OF THE INVENTION With reference to FIG. 1, which illustrates an element (1) for the formation of a curtain guide according to the invention, this element is in the form of a linear profiled piece and This piece comprises a recess (2) made in its thickness on each side of said piece and over most of its length in order to lighten said piece.

This element (1) forms a half-wave, and is intended to cooperate with the same other element (1) to form a corrugation itself.

For this purpose, the element (1) comprises a first end comprising a male-type coupling member (3), and a second end comprising a female-type complementary coupling member (4). The male-type coupling member (3) is in the form of a finger (3a) protruding longitudinally in the extension of the S-shaped element (1). The complementary coupling member of the female type (4) is, in turn, in the form of a receiving screed (4a) of said finger (3a). The finger (3a) of the element (1) is then intended to be hingedly coupled with the receiving clevis (4a) of another element (1) so as to allow the coupling of two elements (1). ) for forming a ripple. Once two elements (1) coupled, the finger (3a) is pivotable in the receiving screed (4a) about an axis orthogonal to the plane comprising the element (1) in the form of 20 S. In this way the two elements (1) are adapted to adopt a so-called unfolded position (see Fig. 2) in which they are spaced apart from one another for the formation of a corrugation, and a so-called folded position (cf. Fig. 3) in which they are brought closer to each other. The pivoting of the finger (3a) in the receiving screed (4a) is limited by two stops. The first stop is located at the level of the cooperation between the finger (3a) and the receiving screed (4a), and limits the spacing of the two elements (1). The first stop stops the gap in the unfolded position in which the two elements (1) form a perfect undulation. The second stop is located at the level of the parts themselves which, when they are close to each other, abut one against the other and stop the bringing together of the two elements (1) in the position folded. With reference to FIG. 5, which represents another embodiment of the element (1) according to the invention, the male-type coupling member (3) is in the form of two parallel protruding cheeks ( 7), defining between them an inclined face (8) forming a stop. The cheeks (7) each comprise on their outer face, a cylindrical lug (9) perpendicularly protruding. On the other side, the female type coupling member (4) is in the form of a receiving screed (10). The receiving screed (10) also defines two parallel cheeks (10a) and projections. The ') of the male type coupling member (3) are intended to be engaged cheeks (10a) of the female type coupling member (4). The two cheeks a) of the female-type coupling member (4) each comprise an orifice (11) for receiving the pins (9) for the coupling to handle (e) A portion (12) projects between the two cheeks (I0a) of the coupling member rte female type (4) .This portion (12) is intended to abut against the inclined face (8), when two elements (I) are coupled and are pivoted until to adopt an unfolded position, in which they are separated from each other for the formation of a corrugation With reference to FIGS. 2, 3 and 5, the successive coupling of a plurality of elements (1 ) forms the guide itself.

This guide is intended to cooperate with the upper or lower longitudinal edge of a curtain, preferably with the upper longitudinal edge, so as, on the one hand, to maintain it in a corrugated conformation, when the latter is unfolded, that is to say in a position of elongation of the curtain, and, secondly, to assist and facilitate the folding of the curtain.

Said guide constituted by the successive coupling of a plurality of elements (1) according to the invention can cooperate in any appropriate manner with the upper or lower longitudinal edge of a curtain. It can indeed be, for example, inserted into a hem that includes this longitudinal edge. Or, according to a preferred but non-limiting embodiment, said guide is inserted into a tubular (5a) formed in the entire length of a ribbon (5) as shown in FIG. 4. The ribbon (5) is then intended to be sewn over the width of the curtain at its longitudinal edge. The ribbon (5) may also comprise a series of regular pockets (5b) arranged along the entire length of the ribbon (5) allowing the insertion, for example, of conventional or specific hooks intended to cooperate with any type of rod or rail for the curtain support. The guide formed by the successive coupling of elements (1) according to the invention is then universal and can adapt to any type of curtain. This guide makes it possible to maintain a curtain in a corrugated conformation. The element (1) according to the invention furthermore comprises a plurality of transverse hyphenation lines (6) regularly distributed over the length of said element (1). This allows in particular to be able to adjust the length of said element (1) to shorten the length at the end of the guide and thus adapt perfectly to the length of the curtain.
