Description

Dispositif facilitant le déplacement d'un rideau à passants Device facilitating the movement of a curtain
La présente invention concerne le domaine des rideaux en matière tissée ou non tissée, avec passants, et plus précisément ceux agencés pour glisser sur une tringle.The present invention relates to the field of curtains of woven or nonwoven material, with loops, and more specifically those arranged to slide on a rod.
Le terme « rideaux » englobe les double rideaux et voilages.The term "curtains" includes double curtains and curtains.
Certains rideaux sont confectionnés avec des passants le plus souvent de même matière, cousus ou attachés autrement, par exemple par boutons pression ou agrafes, en forme de boucle à distance régulière sur la partie haute du rideau, de façon à ce qu'ils puissent être suspendus à une tringle support. Avec ce mode d'accrochage et en l'absence d'autre système, l'ouverture ou la fermeture du rideau est rendue difficile en raison du frottement de la matière des passants sur la tringle, que celle-ci soit en bois, métal ou plastique. L'ouverture ou la fermeture ne peuvent pas être le résultat d'un seul geste et les tentatives multiples faites avec vigueur peuvent fragiliser voir provoquer la déchirure du rideau, des passants ou le descellement de la tringle.Some curtains are made with loops most often of the same material, sewn or otherwise attached, for example by snaps or staples, loop-shaped at a regular distance on the upper part of the curtain, so that they can be hanging on a support rod. With this mode of attachment and in the absence of other system, the opening or closing of the curtain is made difficult because of the friction of the material of the loops on the rod, whether it is wood, metal or plastic. The opening or closing can not be the result of a single gesture and multiple attempts made vigorously can weaken or cause tearing of the curtain, bystanders or loosening of the rod.
Il existe peu de dispositifs appropriés pour résoudre ce problème du glissement des passants sur les tringles.There are few appropriate devices to solve this problem of slippage of the loops on the rods.
La demande EP 1153560 enseigne d'utiliser une pièce cylindrique enfilée autour de la tringle, le passant étant posé sur la partie supérieure de cette pièce. Cette dernière reste visible dans sa partie inférieure et doit être calibrée au diamètre de chaque tringle.EP 1153560 teaches to use a cylindrical piece threaded around the rod, the passer being placed on the upper part of this piece. The latter remains visible in its lower part and must be calibrated to the diameter of each rod.
La demande FR 281 9389 décrit d'utiliser une bague ouverte enfilée autour de la tringle, se fixant en bordure du passant. Cela ne réduit le frottement que partiellement, car la bague ne supprime pas le contact de la tringle avec la partie du passant qui ne repose pas sur cette bague et donc ne résout pas complètement le problème.The application FR 281 9389 describes using an open ring threaded around the rod, fixing at the edge of the loop. This only partially reduces the friction, because the ring does not remove the contact of the rod with the part of the passer that does not rest on this ring and therefore does not solve the problem completely.
La demande WO 9947031 enseigne d'utiliser un demi-cylindre intercalé entre la tringle et le passant, fixé à celui-ci par bande accrochante de type Velcro®. Ce mode de fixation crée une surépaisseur peu esthétique. De plus, l'inconvénient reste que pour fonctionner, le dispositif doit correspondre au diamètre de la tringle.The application WO 9947031 teaches to use a half-cylinder interposed between the rod and the passer, attached thereto by Velcro® type hanging tape. This method of attachment creates an unseen oversize. In addition, the disadvantage remains that to operate, the device must correspond to the diameter of the rod.
Dans le même esprit, la demande FR 2 862 510 divulgue un demi-cylindre présentant en face interne de nombreuses protubérances supposées réduire le frottement sur la tringle et en face externe des excroissances ou picots devant permettre la fixation au passant. Il est dépendant du diamètre de la tringle et les picots traversant le tissu du passant peuvent être visibles et le détériorer. La publication WO 01/95774 enseigne d'utiliser une bande rectangle en matière semi-rigide assez souple pour s'adapter à l'arc de la tringle, qui traverse trois tampons de glissement et les maintient parallèles entre la tringle et la face interne du passant. Des picots en face externe de cette bande et une fixation de type Velcro® permettent de fixer l'ensemble au passant. Suivant le diamètre de la tringle, le positionnement des tampons de glissement ne permet pas d'éviter tout contact du passant avec la tringle. Les picots de fixation peuvent être visibles à travers le tissu du passant et le détériorer. L'installation de ce dispositif est relativement longue et demande de la dextérité.In the same spirit, the application FR 2 862 510 discloses a half-cylinder having in the inner face of many protuberances supposed to reduce the friction on the bead and on the outer face of the protrusions or pins to allow attachment to the passer. It is dependent on the diameter of the rod and the pins passing through the fabric of the passer can be visible and deteriorate. The publication WO 01/95774 teaches the use of a rectangle strip of semi-rigid material flexible enough to adapt to the arc of the rod, which passes through three sliding pads and keeps them parallel between the rod and the inner face of the rod. passing. Pins on the outer face of this band and a Velcro® type fastening make it possible to fix the assembly to the passer-by. Depending on the diameter of the rod, the positioning of the sliding pads does not prevent any contact of the loop with the rod. Fixation pins may be visible through the fabric of the passer and deteriorate. The installation of this device is relatively long and requires dexterity.
La publication WO 99/ 47031 enseigne d'utiliser une seule bande souple dont la face externe adhésive est collée à l'intérieur du passant et la face interne plus glissante assure le contact avec la tringle. Cette solution ne réduit pas la surface de frottement mais seulement son coefficient et résiste difficilement aux lavages ou nettoyages.The publication WO 99/47031 teaches the use of a single flexible band whose adhesive outer face is glued inside the passer and the more slippery internal surface ensures contact with the bead wire. This solution does not reduce the friction surface but only its coefficient and hardly withstands washing or cleaning.
La demande FR 2868 931 divulgue un autre dispositif destiné à faciliter le glissement des passants.The application FR 2868 931 discloses another device for facilitating the sliding of passersby.
La demande EP 1535 548 décrit un élément destiné à être interposé entre la tringle et les passants, comportant d'un côté une pluralité de protubérances permettant de réduire le coefficient de frottement avec la tringle et de l'autre côté des excroissances destinées à l'accrochage de l'élément sur le passant.The application EP 1535 548 describes an element intended to be interposed between the rod and the loops, comprising on one side a plurality of protuberances making it possible to reduce the coefficient of friction with the rod and on the other side of the protrusions intended for the hanging the element on the passer.
Il apparaît que tous ces dispositifs n'apportent que des réponses partielles et non complètement satisfaisantes au problème du glissement des passants sur la tringle, et présentent l'un ou plusieurs des inconvénients suivants : ces dispositifs sont à ajouter après la confection des passants du rideau, leur installation peut être fastidieuse car elle nécessite la dépose des rideaux et l'assemblage de plusieurs éléments, la surface de contact ou de friction avec la tringle reste importante, les dispositifs doivent être adaptés au diamètre de la tringle, la fixation est réversible et susceptible de fragiliser les passants lorsque ceux-ci sont réalisés dans un tissu fin ou fragile.It appears that all these devices provide only partial answers and not completely satisfactory to the problem of slippage passers-by on the rod, and have one or more of the following disadvantages: these devices are to be added after the making of the passers of the curtain , their installation can be tedious because it requires the removal of curtains and the assembly of several elements, the contact surface or friction with the rod remains important, the devices must be adapted to the diameter of the rod, the binding is reversible and likely to weaken passers-by when they are made of a thin or fragile fabric.
Il subsiste par conséquent un besoin pour remédier à l'un au moins de ces inconvénients, grâce à un dispositif destiné à faciliter le glissement des passants, qui soit relativement esthétique, peu coûteux, fiable, facile à installer et présentant un risque diminué d'endommagement des passants. Selon l'un de ses aspects, l'invention a pour objet un dispositif destiné à faciliter le déplacement d'un rideau à passants sur une tringle, comportant au moins deux éléments de glissement à fixer à au moins un passant, chaque élément présentant une face servant à la fixation sur le passant qui est revêtue d'un adhésif, les éléments de glissement étant maintenus avec un écartement prédéfini par des moyens de maintien détachables et/ou flexibles, au moins avant leur pose sur le passant.There is therefore still a need to remedy at least one of these disadvantages, thanks to a device intended to facilitate the sliding of loops, which is relatively aesthetic, inexpensive, reliable, easy to install and having a decreased risk of damage to passersby. According to one of its aspects, the subject of the invention is a device intended to facilitate the movement of a curtain with loops on a bead wire, comprising at least two sliding elements to be fixed to at least one passer, each element having a fastening face on the adhesive-coated lead, the slip members being held at a predetermined distance by detachable and / or flexible holding means, at least prior to being placed on the lead.
Dans un exemple de mise en œuvre de l'invention, les moyens de maintien sont détachables afin d'être séparés des éléments de glissement une fois ces derniers fixés au passant.In an exemplary implementation of the invention, the holding means are detachable in order to be separated from the sliding elements once they are fixed to the loop.
Dans un autre exemple de mise en œuvre de l'invention, les moyens de maintien sont flexibles et ne sont pas séparés des éléments de glissement une fois ces derniers fixés au passant.In another exemplary implementation of the invention, the holding means are flexible and are not separated from the sliding elements once the latter fixed to the passer.
L'invention présente de nombreux avantages.The invention has many advantages.
Tout d'abord, le dispositif peut être relativement simple à fabriquer et à installer, que ce soit lors de la confection des rideaux ou après celle-ci.First, the device can be relatively simple to manufacture and install, whether during the making of curtains or after it.
L'invention permet de réaliser des éléments de glissement qui ne nuisent pas à l'esthétique du rideau, les éléments de glissement pouvant être sensiblement invisibles car uniquement fixés sur la face interne du passant.The invention makes it possible to produce sliding elements that do not detract from the aesthetics of the curtain, the sliding elements being substantially invisible because they are only fixed on the internal face of the passer.
Le bon fonctionnement du dispositif est relativement indépendant du diamètre de la tringle, les éléments de glissement pouvant s'adapter au diamètre de la tringle et à la courbe du passant.The proper operation of the device is relatively independent of the diameter of the rod, the sliding elements can adapt to the diameter of the rod and the curve of the passer.
Ainsi, un rideau équipé des éléments de glissement pourra facilement être monté sur une tringle d'un diamètre différent lors d'une nouvelle installation.Thus, a curtain equipped with sliding elements can easily be mounted on a rod of a different diameter during a new installation.
Le dispositif peut s'adapter aisément à plusieurs diamètres de tringle, notamment lorsqu'il comporte au moins cinq éléments de glissement.The device can easily adapt to several rod diameters, especially when it comprises at least five sliding elements.
La longueur des éléments de glissement peut être facilement adaptée à la largeur du passant, le cas échéant.The length of the sliding elements can be easily adapted to the width of the loop, if any.
Le dispositif peut convenir à tous types de passants, même ceux à nœud.The device can be suitable for all types of passersby, even those with a node.
Les éléments de glissement peuvent être réalisés de façon à maintenir le passant rigide et sans pli dans sa largeur. Cela permet un alignement ordonné entre passants, que le rideau soit en position ouverte ou fermée. Les éléments de glissement permettent d'éviter l'usure des passants et qu'ils noircissent par leur contact sur la tringle. Les éléments de glissement peuvent, dans certaines réalisations où ils s'étendent sur sensiblement toute la largeur du passant, réduire le risque de froissement ou de pli du passant.The sliding elements can be made so as to maintain the rigid passer and without fold in its width. This allows orderly alignment between passers, whether the curtain is in the open or closed position. The sliding elements make it possible to avoid the wear of the loops and that they darken by their contact on the rod. The sliding elements may, in some embodiments where they extend over substantially the entire width of the passer, reduce the risk of creasing or crease of the passer.
Les éléments de glissement peuvent assurer une grande souplesse aux déplacements, en permettant au passant de se soulever légèrement lorsque ce dernier subit une traction latérale, ce que ne peut pas faire une bague ou une pièce cylindrique entourant la tringle.The sliding elements can provide a great flexibility to the movements, allowing the passer to lift slightly when the latter undergoes lateral traction, which can not do a ring or a cylindrical piece surrounding the rod.
Les éléments de glissement, une fois posés, permettent de repasser à plat le passant. Leur présence ne gène pas la mise sous blister du rideau, ne modifie pas la présentation commerciale.The sliding elements, once installed, allow to iron the passer. Their presence does not interfere with the blistering of the curtain, does not change the commercial presentation.
La fixation des éléments de glissement est définitive car résistante au lavage des rideaux.The fixing of the sliding elements is final because resistant to washing curtains.
Le dispositif convient à tous types de rideau : du très léger au très lourd, transparent ou opaque.The device is suitable for all types of curtains: from very light to very heavy, transparent or opaque.
La fabrication du dispositif peut utiliser relativement peu de matière et son coût de production peut rester relativement faible.The manufacture of the device can use relatively little material and its production cost can remain relatively low.
Le dispositif peut aisément être produit en différentes longueurs, suivant la largeur des passants à équiper, souvent de dimensions normalisées.The device can easily be produced in different lengths, depending on the width of the loops to be equipped, often of standardized dimensions.
Le dispositif offre une facilité de mise en œuvre par les opérateurs, les éléments de glissement étant de manipulation aisée avant leur pose, grâce aux moyens de maintien.The device offers ease of implementation by the operators, the sliding elements being easy to handle before installation, thanks to the holding means.
La pose des éléments de glissement peut se faire par collage en exerçant une pression de contact et/ou en utilisant le cas échéant une presse thermique et/ou une activation par ultraviolets ou ultrasons.The laying of the sliding elements can be done by gluing by exerting a contact pressure and / or using, if necessary, a thermal press and / or an activation by ultraviolet or ultrasound.
Le dispositif peut comporter au moins trois, mieux quatre, encore mieux cinq éléments de glissement, voire plus.The device may comprise at least three, better four, even better five or more sliding elements.
Les moyens de maintien peuvent comporter une feuille ou carte pourvue de fentes dans lesquelles les éléments de glissements sont encliquetés. Chaque élément de glissement peut présenter en section transversale une forme en Ω, de façon à s'encliqueter facilement dans la fente correspondante. La feuille ou carte peut être une feuille de papier, de carton ou d'une ou plusieurs matières plastiques, par exemple. Le pré-positionnement des éléments de glissement peut encore s'effectuer autrement que par encliquetage, par exemple au moyen d'un adhésif de faible force entre les éléments de glissement et un support tel qu'une feuille ou carte.The holding means may comprise a sheet or card provided with slots in which the sliding elements are snapped. Each sliding element may have a cross-sectional shape in Ω, so as to snap easily into the corresponding slot. The sheet or card may be a sheet of paper, cardboard or one or more plastics, for example. The pre-positioning of the sliding elements can be carried out other than by snapping, for example by means of a low-force adhesive between the sliding elements and a support such as a sheet or card.
La fixation amovible des éléments de glissement sur un support tel que par exemple une feuille, un film ou carte peut encore s'effectuer par fusion locale de matière, grâce à des points de soudure entre les éléments de glissement et le support.The removable attachment of the sliding elements on a support such as for example a sheet, a film or card can still be made by local melting of material, thanks to the weld points between the sliding elements and the support.
Dans une variante encore, les éléments de glissement sont reliés entre eux par des ponts de matière qui les maintiennent avec un écartement prédéfini. Ces ponts de matière peuvent être sécables de façon à être enlevés une fois les éléments de glissement fixés au passant. En variante, les ponts de matière sont suffisamment flexibles pour être laissés en place sur le passant une fois les éléments de glissement fixés.In another variant, the sliding elements are interconnected by material bridges which maintain them with a predefined spacing. These bridges of material can be scored so as to be removed once the sliding elements attached to the passer. As a variant, the material bridges are sufficiently flexible to be left in place on the loop once the sliding elements have been fixed.
Les moyens de maintien peuvent comporter un repère permettant de positionner le pli du sommet du passant relativement aux éléments de glissement, avant leur fixation sur le passant.The holding means may comprise a mark for positioning the fold of the top of the passer relative to the sliding elements, before their attachment to the passer.
Le repère peut être réalisé par exemple par une marque imprimée ou préformée ou par une découpe d'un support, par exemple sous la forme d'au moins une encoche en V, par exemple deux encoches en V qui se font face sur des bords latéraux du support, ces derniers étant à positionner parallèlement aux bords du passant lors de la mise en place des éléments de glissement sur un passant.The marker may be made for example by a printed or preformed mark or by a cutout of a support, for example in the form of at least one V-notch, for example two V-shaped notches facing each other on lateral edges. the support, the latter being positioned parallel to the edges of the passer when placing the sliding elements on a passer.
Les moyens de maintien peuvent être agencés de manière à être plies en deux en vue de la pose des éléments de glissement sur le passant lorsque celui-ci forme déjà une boucle.The holding means may be arranged to be folded in two for the laying of the sliding elements on the passer when it already forms a loop.
Les moyens de maintien peuvent comporter une ligne de pliage préformée, par exemple une épaisseur de matière moindre, ou une ligne d'affaiblissement, par exemple une rainure ou une découpe destinée à faciliter le pliage selon une ligne prédéfinie.The holding means may comprise a preformed fold line, for example a smaller material thickness, or a weakening line, for example a groove or a cutout intended to facilitate folding along a predefined line.
Dans un exemple de mise en œuvre de l'invention, les moyens de maintien comportent un support tel qu'une feuille ou carte qui est plié dans une région médiane dépourvue d'éléments de glissement. La ligne de pliage du support peut être parallèle aux éléments de glissement ou en variante perpendiculaire à ceux-ci.In an exemplary implementation of the invention, the holding means comprise a support such as a sheet or card which is folded in a median region devoid of sliding elements. The folding line of the support may be parallel to the sliding elements or alternatively perpendicular to them.
Les éléments de glissements sont par exemple plus proches d'un bord libre du support que de la ligne de pliage. Cela peut diminuer le risque de détachement d'éléments de glissement lors du pliage du support et faciliter la manipulation de ce dernier. Une orientation perpendiculaire des éléments de glissement au support peut en faciliter la manipulation.The sliding elements are for example closer to a free edge of the support than the fold line. This can reduce the risk of loose sliding elements during the folding of the support and facilitate the handling of the latter. A perpendicular orientation of the sliding elements to the support can facilitate handling.
L'écartement entre les éléments de glissement est avantageusement supérieur à la largeur d'un élément de glissement, ce qui peut permettre à des éléments de glissement portés par les deux montants opposés d'un passant de s'intercaler.The spacing between the sliding elements is advantageously greater than the width of a sliding element, which may allow sliding elements carried by the two opposite amounts of a passer to intercalate.
L'écartement entre les éléments de glissement peut ainsi être choisi de telle sorte que les éléments de glissement portés par l'un des montants du passant s'intercalent avec les éléments de glissement portés par l'autre montant du passant, lorsque les deux montants du passant sont plaqués l'un contre l'autre, par exemple parce que le rideau est conditionné à plat ou repassé.The spacing between the sliding elements can thus be chosen such that the sliding elements carried by one of the amounts of the passer are interposed with the sliding elements carried by the other amount of the passer, when the two amounts the passerby are pressed against each other, for example because the curtain is packaged flat or ironed.
Dans un exemple de mise en œuvre de l'invention, les éléments de glissement sont disposés sur le support de telle sorte que lorsque le passant est plié, les éléments de glissement les plus éloignés de la ligne de pliage du passant viennent en appui latéralement l'un contre l'autre. Cela peut assurer un positionnement à longueur égale des deux moitiés du passant l'une par rapport à l'autre, ce qui est avantageux lorsque le passant est fixé sur le rideau après la pose des éléments de glissement.In an exemplary implementation of the invention, the sliding elements are arranged on the support so that when the loop is folded, the sliding elements furthest away from the bending line of the loop bear laterally against each other. against each other. This can ensure equal length positioning of the two halves of the passer with respect to each other, which is advantageous when the passer is attached to the curtain after the sliding elements have been applied.
Les éléments de glissement sont avantageusement identiques, au moins une portion des éléments de glissement étant par exemple réalisée par injection ou par extrusion, par exemple dans une matière thermoplastique chargée ou non, telle que du PVC, polyester, polyacrylate, PP ou PE, PBT, polyamide, polyacétal ou un mélange de ceux-ci, cette liste n'étant pas limitative.The sliding elements are advantageously identical, at least a portion of the sliding elements being for example made by injection or by extrusion, for example in a thermoplastic material filled or not, such as PVC, polyester, polyacrylate, PP or PE, PBT , polyamide, polyacetal or a mixture thereof, this list not being limiting.
Les éléments de glissement sont de préférence réalisés avec une matière thermoplastique transparente, ce qui permet de diminuer leur visibilité. Lorsque les moyens de maintien ne sont pas séparés des éléments de glissement une fois ces derniers posés sur le passant, les moyens de maintien sont également avantageusement réalisés avec une matière thermoplastique transparente.The sliding elements are preferably made of a transparent thermoplastic material, which makes it possible to reduce their visibility. When the holding means are not separated from the sliding elements once they are placed on the passer, the holding means are also advantageously made with a transparent thermoplastic material.
Les éléments de glissement s'étendent avantageusement sur au moins la moitié de la largeur du passant, de préférence sur pratiquement toute sa largeur, de façon continue ou non.The sliding elements advantageously extend over at least half of the width of the passer, preferably over substantially its entire width, continuously or not.
Les éléments de glissement peuvent comporter des barrettes ou se présenter sous d'autres formes, étant de préférence tous sous la forme de barrettes. L'invention a encore pour objet un passant comportant au moins deux éléments de glissement indépendants collés à sa face interne, le passant étant déjà fixé au rideau ou à fixer à un rideau.The sliding elements may comprise bars or be in other forms, preferably all in the form of bars. The invention also relates to a passer with at least two independent sliding elements glued to its inner face, the passer being already attached to the curtain or to fix to a curtain.
L'invention a encore pour objet un passant comportant au moins deux éléments de glissement collés dessus et reliés par des moyens de maintien de ces éléments de glissement avant leur pose sur le passant, ces moyens de maintien étant flexibles et de préférence transparents. Le passant peut être fixé à un rideau ou à fixer au rideau.The invention also relates to a loop having at least two sliding elements glued on and connected by means for holding these sliding elements before laying on the passer, these holding means being flexible and preferably transparent. The passer can be attached to a curtain or attached to the curtain.
L'invention a encore pour objet un procédé de fabrication d'un rideau comportant des passants, dans lequel on colle sur au moins un passant au moins deux éléments de glissement, de préférence des éléments de glissement prépositionnés grâce à des moyens de maintien détachables.The invention further relates to a method of manufacturing a curtain with loops, wherein is pasted on at least one pass at least two sliding elements, preferably prepositioned sliding elements with detachable holding means.
Dans des exemples de mise en œuvre de l'invention, le dispositif facilitant le déplacement d'un rideau à passants sur une tringle en supprimant le frottement des passants, est du type comportant des éléments de glissement en forme de barrettes, interposés entre le passant et la tringle, comportant au moins cinq éléments identiques et indépendants les uns des autres, formant un ensemble d'éléments parallèles fixé sur chaque passant avant sa couture au rideau.In examples of implementation of the invention, the device facilitating the movement of a curtain with loops on a rod by eliminating the friction of the loops, is of the type comprising sliding elements in the form of bars, interposed between the passer and the rod, comprising at least five identical and independent elements of each other, forming a set of parallel elements fixed on each passer before sewing the curtain.
Chaque élément, en forme de barrette, peut présenter une partie supérieure plane sur laquelle est déposé un moyen de fixation adhésif destiné à être activé par presse thermique, ultrasons ou ultraviolets, de sorte à être collé individuellement et de façon définitive dans la largeur du passant sur sa face interne lors de la pose du dispositif.Each element, in the form of a bar, may have a planar upper part on which is deposited an adhesive fixing means intended to be activated by thermal press, ultrasonic or ultraviolet, so as to be individually and permanently bonded in the width of the loop on its internal face during the installation of the device.
Les éléments peuvent être pré-positionnés par ensemble d'au moins cinq, lors de leur fabrication, sur une bande support de manipulation amovible et jetable qui maintient de façon temporaire jusqu'à la pose chacun des éléments indépendants composant le dispositif, par leur partie opposée à leur surface plane adhésive, suivant un positionnement qui, une fois les éléments collés sur le passant, crée un intervalle entre chacun d'eux au moins égal à la largeur d'un élément, de façon à ce qu'ils puissent s'intercaler les uns entre les autres quand le passant ainsi équipé est plié en deux pour être cousu au rideau, repassé ou conditionné à plat, et d'une valeur supérieure calculée de façon à supprimer tout contact du passant avec la tringle quelque soit son diamètre.The elements may be pre-positioned by a set of at least five, during their manufacture, on a removable and disposable handling support strip which temporarily holds each of the independent elements that make up the device, by their part. opposed to their adhesive flat surface, according to a positioning which, once the elements glued to the passer, creates a gap between each of them at least equal to the width of an element, so that they can s' intercalate between each other when the passer thus equipped is folded in half to be sewn to the curtain, ironed or packaged flat, and a higher value calculated so as to remove any contact of the passer with the rod regardless of its diameter.
Dans des exemples de réalisation non limitatifs de l'invention : chaque élément de glissement de forme allongée peut présenter, en complément de sa surface destinée à recevoir la matière adhésive servant à le fixer à la face interne du passant, une forme ayant une section transversale choisie parmi une section polygonale, notamment rectangulaire, carrée, triangulaire, semi- cylindrique ou en

extrémités, une protubérance comprimable, par exemple en forme d'arc de cercle ou de nervure convexe vers l'extérieur, dont la forme associée à la souplesse du matériau permet à la presse d'appliquer une pression égale sur l'ensemble de l'élément afin d'assurer un collage optimum de toute sa surface, chaque élément de glissement peut comporter du côté destiné à venir au contact de la tringle, une succession de bossages, par exemple chacun de forme sensiblement sphérique, venant en contact avec la tringle à leur sommet, ces bossages peuvent être répartis sur l'élément de glissement avec un écartement plus grand entre eux dans une région médiane de l'élément de glissement, afin de préserver une certaine flexibilité à l'élément de glissement, les éléments de glissement peuvent être positionnés, par exemple à intervalles réguliers, en rangées sur le support, les éléments de glissement ayant par exemple chacun une surface sensiblement hémisphérique destinée à contacter la tringle,

un décrochement ou une épaisseur moindre au centre ou à l'une ou l'autre extrémité ou aux deux extrémités, pour compenser les surépaisseurs que provoque toute couture de fabrication du passant selon qu'elle est réalisée en partie centrale ou latéralement, chaque élément de glissement peut par exemple comporter sur sa face en regard du passant un évidement, par exemple de forme cylindrique d'axe perpendiculaire à l'axe longitudinal de l'élément de glissement, obtenu par exemple par fraisage de l'élément, l'évidement pouvant encore présenter une forme autre, notamment lorsque l'élément de glissement est réalisé par injection, les éléments de glissement peuvent comporter sur leur face destinée à adhérer au passant un état de surface destiné à faciliter l'accrochage de l'adhésif, les éléments de glissement peuvent présenter sur la face assemblée au passant une rainure longitudinale centrale, par exemple à fond arrondi en section transversale, une telle rainure réduisant la quantité de matière de l'élément de glissement et pouvant faciliter la manipulation mécanisée des éléments de glissement lors de la fabrication, les éléments de glissement peuvent comporter un ou plusieurs ajours latéraux, notamment en cas de réalisation par injection, afin de diminuer la quantité de matière servant à les réaliser.In non-limiting exemplary embodiments of the invention: each

positioned, for example at regular intervals, in rows on the support, the sliding elements having for example each a substantially hemispherical surface intended to contact the rod, a non-adherent protective film may be in contact with the adhesive material deposited on each element slip and cover all the elements, each sliding element can present a recess or a lower thickness in the center or at one end or the other end or to both ends, to compensate for the extra thicknesses that causes any sewing manufacturing of the passer according to whether it is made in the central part or laterally, each element of slip may for example have on its face facing the passer a recess, for example of cylindrical shape of axis perpendicular to the longitudinal axis of the sliding element, obtained for example by milling the element, the recess may still have a different shape, especially when the sliding element is made by injection, the sliding elements may comprise on their face intended to adhere to the passing a surface state intended to facilitate the adhesion of the adhesive, the sliding elements may have on the face assembled to the passer a central longitudinal groove, for example with a rounded bottom in cross section, such groove reducing the amount of material of the sliding element and may facilitate the mechanized handling of the sliding elements during manufacture, the sliding elements may comprise one or more lateral openings, particularly in the case of injection molding, in order to reduce the amount of material used to make them.
L'invention a encore pour objet, selon un autre de ses aspect, un procédé de fabrication d'un dispositif tel que défini plus haut, dans lequel chaque élément de glissement est fabriqué par injection ou extrusion de matière semi-rigide suivie par l'application de matière adhésive du type destinée à être activée par pression à chaud, ultraviolets ou ultrasons lors de la pose sur le passant, puis positionné sur un support de manipulation et éventuellement recouvert par un film protecteur.The invention further relates, in another of its aspects, to a method of manufacturing a device as defined above, in which each sliding element is manufactured by injection or extrusion of semi-rigid material followed by the application of adhesive material of the type intended to be activated by hot pressure, ultraviolet or ultrasound when laying on the loop, then positioned on a handling medium and possibly covered by a protective film.
L'invention s'étend également à un rideau caractérisé en ce qu'il comporte des passants sur chacun desquels sont collés les éléments de glissement d'un dispositif selon l'invention, ces éléments de glissement étant positionnés relativement au passant préalablement à leur fixation sur le passant de façon à ce qu'un coté de l'élément central soit adjacent à la ligne de pliage du passant, ce décalage par rapport à ce pli supérieur médian et les intervalles entre les éléments de glissement permettant à l'ensemble desdits éléments de s'intercaler lorsque le passant, une fois équipé, est plié en deux pour être cousu au rideau, être repassé ou conditionné à plat.The invention also extends to a curtain characterized in that it comprises loops on each of which are glued the sliding elements of a device according to the invention, these sliding elements being positioned relatively to the passer before their fixation on the passer so that one side of the central element is adjacent to the fold line of the passer, this offset with respect to this median upper fold and the intervals between the sliding elements allowing all of said elements to intercalate when the passerby, once equipped, is folded in two to be sewn to the curtain, ironed or packaged flat.

This device comprises a support 12 serving as holding means, on which sliding elements 1 are prepositioned before attachment to the passer.
Le support 12 se présente par exemple sous la forme d'une bande de papier, de carton, de métal ou d'un film plastique. Dans l'exemple illustré, le dispositif comporte cinq éléments de glissement 1 identiques, se présentant chacun sous la forme d'une barrette, telle que par exemple celle représentée isolément à la figure 8.The support 12 is for example in the form of a strip of paper, cardboard, metal or a plastic film. In the example illustrated, the device comprises five identical sliding elements 1, each in the form of a bar, such as for example that shown in isolation in FIG. 8.
Chaque élément 1 en forme de barrette présente une face 4 sur laquelle est déposé un adhésif 8 par exemple du type destiné à être activé par presse thermique, ultraviolets ou ultrasons, de sorte à être collé individuellement et de façon définitive dans la largeur du passant 9 sur sa face interne. L'adhésif est par exemple celui commercialisé sous la référence THERMELT base polyamide par la société BOSTIK, l'élément de glissement étant par exemple réalisé en cristamid base copolyamide ou PBT base polyester.Each element 1 in the form of a bar has a face 4 on which is deposited an adhesive 8 for example of the type intended to be activated by thermal press, ultraviolet or ultrasound, so as to be individually and permanently bonded in the width of the passer 9 on its inner side. The adhesive is, for example, that marketed under the reference THERMELT polyamide base by the company BOSTIK, the slip element being for example made of cristamid base copolyamide or PBT base polyester.
Il n'y a pas de picot, ni clip ou attache de type Velcro® comme autre système de fixation dans l'exemple illustré.There is no pin, clip or Velcro ® type fastener as other fastening system in the illustrated example.
Chaque élément 1 peut présenter en section transversale une forme générale en Ω comme illustré à la figure 8.Each element 1 may have in cross section a general shape in Ω as illustrated in FIG. 8.
Une telle section permet de définir deux gorges longitudinales opposées 101 et 102 qui servent à l'encliquetage de l'élément de glissement dans une fente traversante du support 12, comme illustré à la figure 7.Such a section makes it possible to define two opposite longitudinal grooves 101 and 102 which serve to snap the sliding element into a through slot of the support 12, as illustrated in FIG. 7.
La section transversale de chaque élément de glissement 1 peut être constante ou non.The cross section of each sliding element 1 may be constant or not.
Dans l'exemple illustré à la figure 8, l'élément de glissement présente un évidement central 118 à mi- longueur, par exemple de forme cylindrique autour d'un axe K perpendiculaire à l'axe longitudinal de l'élément de glissement. Un tel évidement 118 est par exemple obtenu par fraisage de l'élément de glissement lorsque ce dernier est fabriqué par extrusion mais peut encore être réalisé par moulage.In the example illustrated in Figure 8, the sliding element has a central recess 118 at mid-length, for example of cylindrical shape about an axis K perpendicular to the longitudinal axis of the sliding element. Such a recess 118 is for example obtained by milling the sliding element when the latter is manufactured by extrusion but can still be made by molding.
La face 4 peut comporter une rainure 104 à mi-largeur. Une telle rainure 104 permet de réduire la quantité de matière servant à réaliser l'élément de glissement et peut faciliter son convoyage mécanisé après la fabrication.The face 4 may comprise a groove 104 at mid-width. Such a groove 104 reduces the amount of material used to make the sliding element and can facilitate its mechanized conveying after manufacture.
Les éléments de glissement 1 sont prévus dans l'exemple des figures 6 à 8 pour être collés au passant lorsque maintenus par le support 12, puis ce dernier est enlevé.The sliding elements 1 are provided in the example of Figures 6 to 8 to be glued to the passer when held by the support 12, and the latter is removed.
Dans l'exemple illustré, chaque élément de glissement est prévu pour venir en contact avec la tringle sur toute la longueur de la génératrice de sommet 106. En variante, chaque élément de glissement 1 peut avoir un contact avec la tringle sur une portion seulement de sa longueur, par exemple avoir comme seuls points de contact avec la tringle 7 des régions proches de ses extrémités axiales 3 afin de réduire le plus possible le coefficient de frottement. La zone de contact de l'élément 1 avec la tringle 7 est matérialisée par exemple comme illustré à la figure 1 par une protubérance 3 comprimable, par exemple en forme d'arc de cercle, ou de nervure convexe dont la forme associée à la souplesse du matériau, permet à la presse d'appliquer une pression égale sur toute la longueur de l'élément 1 afin d'assurer un collage optimum de toute sa surface lors de l'opération de fixation au passant 9.In the illustrated example, each sliding element is provided to come into contact with the rod over the entire length of the vertex generator 106. As a variant, each sliding element 1 may have contact with the bead wire over only a portion of its length, for example having, as sole points of contact with the bead wire 7, regions near its axial ends 3 in order to reduce as much as possible the coefficient of friction. The zone of contact of the element 1 with the bead wire 7 is embodied for example as illustrated in FIG. 1 by a compressible protrusion 3, for example in the form of an arc of a circle, or of a convex rib whose shape associated with the flexibility of the material, allows the press to apply equal pressure over the entire length of the element 1 to ensure optimum bonding of its entire surface during the fastening operation to the passer 9.
Dans l'exemple des figures 1 et 2, les éléments 1 sont pré-positionnés lors de leur fabrication par ensemble de cinq au moins sur une bande support de manipulation 12, amovible et jetable, qui maintient, de façon temporaire jusqu'à leur pose, chaque élément 1 par sa partie opposée 5 à sa surface 4 adhésive, cette dernière étant plane dans l'exemple illustré.In the example of FIGS. 1 and 2, the elements 1 are pre-positioned during their manufacture by a set of at least five on a removable and disposable handling support band 12, which maintains, temporarily until their installation , each element 1 by its opposite portion 5 to its adhesive surface 4, the latter being flat in the illustrated example.
La matière adhésive déposée sur la surface 4 est protégée par un film protecteur non adhérent 13 pouvant recouvrir l'ensemble des éléments si nécessaire.The adhesive material deposited on the surface 4 is protected by a non-adherent protective film 13 which can cover all the elements if necessary.
Les éléments de glissement peuvent ainsi se présenter pris en sandwich entre bande support de manipulation 12 et le film protecteur non adhérent 13 tel que représenté en figure 2.The sliding elements may thus be sandwiched between the handling support strip 12 and the non-adherent protective film 13 as shown in FIG. 2.
Par leur positionnement sur la bande support de manipulation 12, les éléments 1 libèrent un intervalle 10 entre chacun d'eux. Ces intervalles entre les éléments 1 sont calculés de façon à supprimer tout contact du passant 9 avec la tringle 7 quelque soit son diamètre. Un intervalle 10 est au moins égal à la largeur d'un élément 1 et l'intervalle est d'une valeur supérieure pour celui concernant les éléments latéraux la et le du dispositif.By their positioning on the handling support strip 12, the elements 1 release a gap 10 between each of them. These intervals between the elements 1 are calculated so as to eliminate any contact of the loop 9 with the rod 7 whatever its diameter. An interval 10 is at least equal to the width of an element 1 and the interval is greater than that for the lateral elements 1a and 1e of the device.
L'élément central Ic de l'ensemble des cinq éléments est placé adjacent à la ligne de pliage médiane 11 de la face interne du passant 9.The central element Ic of all five elements is placed adjacent to the median fold line 11 of the inner face of the passer 9.
Cette disposition des éléments entre eux et par rapport au pli médian du passant 11 leur permet de s'intercaler les uns entre les autres quand le passant 9, une fois équipé, est plié en deux pour être cousu au rideau, être repassé ou conditionné à plat.This arrangement of the elements between them and with respect to the median fold of the passer 11 allows them to be interposed with each other when the passer 9, once equipped, is folded in half to be stitched to the curtain, ironed or conditioned to dish.
Le film protecteur 13 ayant été préalablement retiré la bande support de manipulation 12 permet d'ajuster le positionnement de l'ensemble des éléments sur la face interne de chaque passant 9 afin de respecter le placement de l'élément central Ic adjacent à la ligne de pliage médiane, opération facilitée par la présence d'un repère 14 sur la bande support de manipulation 12, tel qu'illustré à la figure 3.The protective film 13 having previously been removed from the handling support strip 12 makes it possible to adjust the positioning of all the elements on the internal face of each passer 9 in order to respect the placement of the adjacent central element Ic. at the median fold line, operation facilitated by the presence of a marker 14 on the handling support strip 12, as shown in Figure 3.
Cette bande support de manipulation 12 peut comporter à titre de moyen de maintien temporaire des éléments un adhésif repositionnable.This handling support strip 12 may comprise as a means for temporarily holding the elements a repositionable adhesive.
Après la fixation par collage des éléments de glissement sur la face interne du passant, la bande 12 peut se détacher des éléments 1, lesquels sont désolidarisés les uns des autres. Le passant 9 ainsi équipé du dispositif est alors prêt à être cousu au rideau, le cas échéant.After gluing of the sliding elements on the inner face of the passer, the strip 12 can be detached from the elements 1, which are separated from each other. The passer 9 and equipped with the device is then ready to be sewn to the curtain, if necessary.
Chaque élément 1 peut présenter au niveau de la surface plane 4, comme illustré, une épaisseur moindre dans au moins une zone choisie définie, soit au centre 6 soit à l'une ou l'autre extrémité ou aux deux extrémités 2 pour compenser les surépaisseurs que provoque toute couture de fabrication du passant 9, selon que cette couture est réalisée en partie centrale ou latéralement.Each element 1 may have at the level of the flat surface 4, as illustrated, a smaller thickness in at least one defined selected zone, either at the center 6 or at one or the other end or at both ends 2 to compensate for the extra thicknesses. that causes any seam production of the loop 9, depending on whether the seam is made in central part or laterally.
Chaque élément 1 peut présenter une zone de collage sensiblement équivalente à la largeur du passant le rendant solidaire du passant 9 sur quasiment toute sa largeur par l'action du collage, de sorte à maintenir le passant 9 sans pli ni repli malgré la répétition des tractions latérales lors de l'ouverture ou fermeture du rideau.Each element 1 may have a bonding area substantially equivalent to the width of the passer making it integral with the passer 9 over almost its entire width by the action of the bonding, so as to maintain the passer 9 without fold or fold despite the repetition of the pulls side when opening or closing the curtain.
Bien entendu, la longueur des éléments est adaptée à la largeur du passant, étant ajustable si nécessaire par découpe des extrémités.Of course, the length of the elements is adapted to the width of the loop, being adjustable if necessary by cutting the ends.
Dans la variante illustrée à la figure 9, les éléments de glissement 1 sont reliés par des ponts de matière 140 qui les maintiennent avec un écartement prédéfini.In the variant illustrated in Figure 9, the sliding elements 1 are connected by material bridges 140 which hold them with a predefined spacing.
Les ponts de matière 140 peuvent être sécables et enlevés après collage des éléments de glissement sur le passant. En variante, les ponts de matière sont laissés en place après la pose des éléments de glissement. Dans ce cas, les ponts de matière 140 sont suffisamment flexible pour ne pas gêner le fonctionnement du passant ni nuire à son aspect.The material bridges 140 can be scored and removed after gluing of the sliding elements to the loop. As a variant, the material bridges are left in place after the sliding elements have been laid. In this case, the material bridges 140 are flexible enough not to interfere with the operation of the passer or impair its appearance.
Les ponts de matière 140 et les éléments de glissement sont par exemple réalisés par injection d'une matière thermoplastique transparente.The material bridges 140 and the sliding elements are for example made by injection of a transparent thermoplastic material.
Dans la variante des figures 10 et 11, chaque élément de glissement 1 est formé par un corps 150 et une portion de base 151 d'un film 152, fixée par une face au corps 150 et portant par l'autre face 153 l'adhésif 8. Le film 152 est par exemple un film d'une matière thermoplastique transparente, de faible épaisseur, commun à tous les éléments de glissement.In the variant of FIGS. 10 and 11, each sliding element 1 is formed by a body 150 and a base portion 151 of a film 152, fixed by one face to the body 150 and bearing on the other face 153 the adhesive 8. The film 152 is for example a film of a Transparent thermoplastic material, thin, common to all sliding elements.
Les portions de liaison 154 reliant les portions de base 151 fixées aux corps 150 constituent des moyens de maintien des éléments de glissement avec un écartement prédéfini. Les portions de liaison 154 sont flexibles et restent en place après collage sur le passant.The connecting portions 154 connecting the base portions 151 fixed to the body 150 constitute means for holding the sliding elements with a predefined spacing. The connecting portions 154 are flexible and remain in place after gluing on the passer.
Dans la variante illustrée à la figure 12, des pluralités d'éléments de glissement sont disposés en rangées 110 parallèles.In the variant illustrated in FIG. 12, pluralities of sliding elements are arranged in parallel rows 110.
Chaque pluralité peut remplacer un élément de glissement en forme de barrette des exemples précédemment décrits.Each plurality may replace a bar-shaped slide member of the previously described examples.
Chaque élément de glissement 1 se présente par exemple sous la forme d'une demi-sphère ou d'un pion, étant fixé de façon amovible sur le support 12.Each sliding element 1 is for example in the form of a hemisphere or a pin, being removably attached to the support 12.
Au sein d'une rangée 110, les éléments de glissement peuvent être identiques ou différents. L 'écartement entre eux peut être constant ou non.Within a row 110, the sliding elements may be the same or different. The spacing between them can be constant or not.
Chaque élément de glissement peut recevoir, le cas échéant, un traitement de surface destiné à réduire le frottement, par exemple un dépôt d'un matériau de faible coefficient de frottement. En variante, chaque élément de glissement est réalisé par bi- injection de matière, avec par exemple un matériau souple pour réaliser la base de l'élément de glissement fixée au passant et un matériau à moindre coefficient de frottement pour venir en contact avec la tringle.Each sliding element may receive, if necessary, a surface treatment intended to reduce friction, for example a deposit of a low friction material. As a variant, each sliding element is made by bi-injection of material, with for example a flexible material for producing the base of the sliding element fixed to the loop and a material with a lower coefficient of friction for coming into contact with the rod. .
On a illustré à la figure 13 la possibilité pour les éléments de glissement, par exemple ceux en forme de barrette précédemment décrits, d'être positionnés sur le support 12 de telle sorte que les éléments de glissement les plus éloignés du sommet du passant viennent latéralement en appui quand le passant est plié.FIG. 13 illustrates the possibility for the sliding elements, for example those in the form of bars previously described, to be positioned on the support 12 so that the sliding elements furthest from the top of the passer come laterally. in support when the passerby is folded.
Cela permet de positionner avec précision les deux moitiés du passant avant sa pose sur le rideau lorsque les éléments de glissement sont collés sur un passant en attente d'être fixé au rideau.This makes it possible to precisely position the two halves of the passer before it is placed on the curtain when the sliding elements are glued to a passerby waiting to be fixed to the curtain.
L'élément de glissement 1 représenté à la figure 14 comporte du côté opposé à la face 4 une pluralité de bossages 210, par exemple chacun de forme sensiblement sphérique, qui sont destinés à venir au contact de la tringle à leur sommet. Ces bossages 210 sont par exemple réalisés par injection avec l'élément de glissement. Leur nombre est par exemple compris entre six et vingt. Les bossages 210 peuvent être disposés de manière à ménager entre eux un intervalle 213 plus grand dans la région médiane de l'élément de glissement de façon à préserver la flexibilité de celui-ci.The sliding element 1 shown in FIG. 14 comprises on the opposite side to the face 4 a plurality of bosses 210, for example each of substantially spherical shape, which are intended to come into contact with the rod at their top. These bosses 210 are for example made by injection with the sliding element. Their number is for example between six and twenty. The bosses 210 may be arranged to provide a greater gap 213 between them in the median region of the slide member so as to preserve the flexibility thereof.
Un ou plusieurs ajours 220 peuvent être réalisés à travers l'élément de glissement entre les rainures 101 et 102 pour alléger l'élément de glissement, comme illustré sur cette figure.One or more openings 220 may be made through the sliding element between the grooves 101 and 102 to lighten the sliding element as shown in this figure.
Dans la variante illustrée à la figure 15, le support 12 comporte dans une région médiane une ligne de pliage 260, comportant par exemple une rainure et les éléments de glissement 1 sont rapprochés des bords libres opposés 261 et 262 du support 12. Celui-ci peut être proposé à l'utilisateur déjà plié, avec les faces 4 apparentes. Le support 12 peut être maintenu plié par coopération de découpes 170 et 171 réalisées dans celui-ci.In the variant illustrated in FIG. 15, the support 12 comprises in a median region a fold line 260, comprising for example a groove and the sliding elements 1 are brought closer to the opposite free edges 261 and 262 of the support 12. This can be proposed to the already folded user, with the apparent faces 4. The support 12 can be kept folded by cooperation of cuts 170 and 171 made therein.
Dans la variante illustrée à la figure 16, les éléments de glissement sont réalisés sous forme de barrettes orientées perpendiculairement à la ligne de pliage. Des éléments de glissement 1 sont présents sur chaque volet du support 12 et peuvent s'intercaler lorsque le support 12 est replié sur lui-même, en vue de la pose des éléments de glissement sur le passant.In the variant illustrated in Figure 16, the sliding elements are formed in the form of strips oriented perpendicularly to the fold line. Sliding elements 1 are present on each flap of the support 12 and can be interposed when the support 12 is folded on itself, for the purpose of placing the sliding elements on the passer.
La largeur du support 12, mesurée perpendiculairement à la ligne de pliage, est supérieure au double de la largeur du passant, de telle sorte qu'une fois le support plié, une portion du support adjacente à la ligne de pliage déborde latéralement du passant, cette portion étant dépourvue d'éléments de glissement et facile à manipuler pour un positionnement précis des éléments de glissement sur le passant.The width of the support 12, measured perpendicularly to the fold line, is greater than twice the width of the loop, so that once the folded support, a portion of the support adjacent to the fold line protrudes laterally from the loop, this portion being devoid of sliding elements and easy to handle for precise positioning of the sliding elements on the passer.
Bien entendu, l'invention n'est pas limitée aux exemples illustrés. Des particularités de réalisation de ces exemples peuvent être combinées entre elles au sein de variantes non illustrées.Of course, the invention is not limited to the illustrated examples. Embodiments of these examples may be combined with each other within non-illustrated variants.
Les termes « amovible » et « détachable » doivent être compris comme étant synonymes.The terms "removable" and "detachable" should be understood as synonymous.
L'expression « comportant un » doit se comprendre comme étant synonyme de « comportant au moins un ». The expression "comprising one" must be understood as being synonymous with "having at least one".
