Abstract
Description
L'invention se rapporte au domaine des accessoires pour la décoration et l'ameublement. Elle vise plus particulièrement un élément pour faciliter les opérations d'ouverture et de fermeture d'un rideau directement enfilé sur une barre par des pattes ou des noeuds notamment en textile. On désignera par la suite par le terme "rideau" toute étoffe suspendu à une barre.The invention relates to the field of accessories for decoration and furnishings. It aims more particularly at an element to facilitate the opening and closing a curtain directly on a bar by legs or knots including textile. We will then designate by the term "curtain" any fabric hanging on a bar.
De façon générale, les éléments anti-friction pour un rideau à pattes sont complexes et longs à mettre en place. En effet, ils comportent plusieurs organes distincts qu'il faut mettre en place individuellement, à la fois sur la barre et sur la patte.In general, the anti-friction elements for a curtain with legs are complex and long to put in place. Indeed, they comprise several organs that must be put in place individually, both on the bar and on the paw.
De tels éléments anti-friction ont été décrits dans les documents EP 0 983 011 et WO 01/95774.Such anti-friction elements have been described in the documents EP 0 983 011 and WO 01/95774.
En effet, pour les dispositifs décrits dans ces deux documents, il est nécessaire de préalablement coller une portion de bande Velcro® à l'intérieur de la patte. Cette bande coopère avec une portion complémentaire rapportée sur l'élément anti-frottement ou alors avec des pointes directement formées par l'élément anti-frottement.Indeed, for the devices described in these two documents, it is necessary to previously glue a portion of Velcro® tape inside the paw. This strip cooperates with a complementary portion reported on the anti-friction element or else with spikes directly formed by the anti-friction element.
Un autre élément spécialement adapté pour les rideaux à noeuds a été décrit dans le document WO 00/60985. Il présente un élément comportant un oeillet qui permet d'insérer une portion du dispositif dans le noeud, et deux rebords pour bloquer les deux bandes de la patte sur ledit élément. Another element specially adapted for knot curtains has been described in WO 00/60985. It has an element with an eyelet that allows to insert a portion of the device in the node, and two edges for block the two strips of the tab on said element.
Ainsi, dans ce cas, aucun moyen apte à réaliser la cohésion réversible entre l'élément et la bande du rideau n'est présent. Cependant, l'utilisation de cet élément est restreinte car elle est limitée aux rideaux à noeuds.Thus, in this case, no means capable of achieving reversible cohesion between the element and the band of the curtain is present. However, the use of this element is restricted because it is limited to knot curtains.
De plus, dans les trois documents précédemment cités, l'élément anti-friction possède une grande surface de contact avec la barre à rideau. Par conséquent, bien que pouvant utiliser un matériau anti-friction, il peut persister des difficultés pour ouvrir ou fermer le rideau sur une telle barre.In addition, in the three documents mentioned above, the anti-friction element has a large contact area with the curtain bar. Therefore, well may use an anti-friction material, there may be difficulties in open or close the curtain on such a bar.
En effet, la surface de frottement entre la barre et l'élément anti-friction est alors relativement importante est répartie. De ce fait, les caractéristiques anti-friction ne sont pas optimales.Indeed, the friction surface between the bar and the anti-friction element is then relatively large is distributed. As a result, the anti-friction characteristics are not optimal.
L'invention concerne donc un élément destiné à être interposé entre une barre à rideau et des pattes d'accrochage d'un rideau, de façon à réduire le coefficient de frottement entre les deux éléments et ainsi faciliter le coulissement d'un rideau de ce type sur une barre. Cet élément anti-friction présente une face interne au regard de la barre apte à coulisser librement par rapport à celle-ci, et une surface externe au regard de la face interne d'une patte d'accrochage.The invention therefore relates to an element intended to be interposed between a bar curtains and tabs of a curtain, so as to reduce the coefficient of friction between the two elements and thus facilitate the sliding of a curtain of this guy on a bar. This anti-friction element has an inner face to the eye of the bar slidable freely relative thereto, and an outer surface with regard to the internal face of a hooking tab.
Conformément à l'invention, il se caractérise en ce qu'il comporte:
- sur sa face interne, une pluralité de protubérances aptes à répartir le poids du rideau sur une zone étendue, tout en réduisant la surface de contact avec la barre ;
- sur sa face externe, une pluralité d'excroissances aptes à pénétrer au moins partiellement dans l'épaisseur de la patte de façon à rester solidaire de celle-ci.
- on its inner face, a plurality of protuberances capable of distributing the weight of the curtain over an extended area, while reducing the contact surface with the bar;
- on its outer face, a plurality of protuberances able to penetrate at least partially into the thickness of the tab so as to remain attached thereto.
Autrement dit, l'élément anti-frottement présente sur sa face interne les moyens pour réduire la surface de frottement tout en répartissant l'effort sur une zone étendue. In other words, the anti-friction element has on its internal face the means to reduce the friction surface while distributing the force on a extended area.
Selon l'invention, il comporte également sur sa face externe des moyens permettant d'aggriper la patte du rideau en pénétrant au moins partiellement dans son épaisseur.According to the invention, it also comprises on its outer face means to grip the tab of the curtain by penetrating at least partially into its thickness.
De cette manière, aucun élément annexe n'est utilisé pour mettre en place cet élément au niveau de chaque patte.In this way, no additional element is used to set up this element at each leg.
Selon un mode de réalisation particulier, les protubérances peuvent être des portions de sphères. De cette manière, le contact entre la barre et l'élément anti-friction s'effectue de manière quasi ponctuelle, dans une zone pouvant s'étendre sur toute la surface de la face interne de l'élément.According to a particular embodiment, the protuberances may be portions of spheres. In this way, the contact between the bar and the anti-friction element almost punctual, in an area that may extend over the entire surface of the inner face of the element.
De même, en pratique, les excroissances de la face externe de l'élément anti-friction peuvent être des pointes. De cette manière, elles pénètrent dans l'épaisseur de la patte du rideau sous l'action du poids du rideau.Similarly, in practice, the protuberances of the outer face of the anti-friction element can be spikes. In this way, they penetrate into the thickness the curtain paw under the weight of the curtain.
Avantageusement, l'élément anti-friction peut être réalisé par un procédé d'injection. Ainsi, le matériau choisi peut être un matériau organique présentant des caractéristiques anti-friction. Il est alors injecté par une méthode haute pression dans un moule.Advantageously, the anti-friction element can be produced by a method injection. Thus, the material chosen may be an organic material having anti-friction characteristics. It is then injected by a high pressure method in a mold.
En pratique, l'élément anti-friction peut également être réalisé en plusieurs étapes. Pour ce faire, un support lisse est préalablement formé. Les faces internes et externes sont ensuite surmoulées sur ce support.In practice, the anti-friction element can also be made in several steps. To do this, a smooth support is previously formed. Internal faces and external are then overmolded on this support.
Avantageusement, le matériau utilisé pour former les faces interne et externe peut présenter une rigidité supérieure à celle utilisée pour le support. De cette manière, l'élément présente alors une certaine souplesse favorisant sa déformation, et lui permettant de s'adapter à différents diamètres de barres à rideau. Advantageously, the material used to form the inner and outer faces may have a rigidity greater than that used for the support. Of this way, the element then has a certain flexibility favoring its deformation, and allowing it to adapt to different diameters of curtain rods.
Avantageusement, le support comporte une section transversale en arc de cercle, de cette manière il peut venir s'encliqueter sur différents diamètres de barres à rideau.Advantageously, the support comprises a cross-section in an arc of circle, in this way it can snap on different bar diameters curtain.
Ainsi, une fois la mise en place de l'élément sur la barre à rideau effectuée, il faut exercer un effort de traction sur l'élément pour le désolidariser la barre.Thus, once the element has been put in place on the curtain rod, must exert a pulling force on the element to disengage the bar.
Avantageusement, le matériau utilisé pour former la face interne de l'élément peut comporter des propriétés anti-friction. A cet égard, une couche de matériaux présentant un faible coefficient de frottement peut être utilisé et notamment du polytetrafluoroéthylène.Advantageously, the material used to form the inner face of the element may have anti-friction properties. In this respect, a layer of materials having a low coefficient of friction may be used and in particular polytetrafluoroethylene.
La manière de réaliser l'invention ainsi que les avantages qui en découlent
ressortiront bien de la description du mode de réalisation qui suit, donnée à titre
indicatif et non limitatif, à l'appui des figures annexées dans lesquelles :
Comme déjà évoqué, l'invention concerne un élément destiné à être interposé entre une barre à rideau et des pattes d'accrochage d'un rideau.As already mentioned, the invention relates to an element intended to be interposed between a curtain rod and tabs of a curtain.
Tel que représenté en figure 1, l'élément (1), qui présente une forme arrondie, vient s'encliqueter sur la barre (2). Il est ensuite inséré à l'intérieur d'une patte (3) d'un rideau (4).As represented in FIG. 1, the element (1), which has a rounded shape, snap on the bar (2). It is then inserted inside a paw (3) a curtain (4).
De cette manière, la face externe (6) de l'élément (1) est alors en regard de la face interne (7) de la patte d'accrochage (3). De même, la face interne (5) de l'élément (1) est en regard de la surface externe de la barre (2). In this way, the outer face (6) of the element (1) is then opposite the internal face (7) of the latching lug (3). Similarly, the inner face (5) of the element (1) is opposite the outer surface of the bar (2).
Tel que représentée à la figure 2, la face interne (5) de l'élément anti-friction (1) comporte des protubérances pour permettre de répartir le poids du rideau sur une zone étendue tout en réduisant la surface de contact avec la barre (2).As shown in FIG. 2, the internal face (5) of the anti-friction element (1) has protuberances to allow to distribute the weight of the curtain on an extended area while reducing the contact area with the bar (2).
Dans cette présentation, les protubérances sont choisies comme étant des portions de sphères.In this presentation, the protuberances are selected as portions of spheres.
De cette manière, le contact entre la barre et l'élément anti-friction se fait au moyen d'un certain nombre de contacts ponctuels.In this way, the contact between the bar and the anti-friction element is through a number of one-off contacts.
D'autre part, les excroissances (9) sont ici représentées par des pointes aptes à pénétrer au moins partiellement dans l'épaisseur de la patte (3) de façon à permettre à l'élément anti-friction en regard de rester solidaire de celle-ci. Bien entendu, la forme, la disposition et les dimensions de ses excroissances peuvent différer de celles illustrées à la figure 3.On the other hand, the protuberances (9) are here represented by spikes able to penetrate at least partially into the thickness of the tab (3) so as to allow the anti-friction element opposite to remain attached to it. Good understood, the shape, the arrangement and the dimensions of its excrescences can differ from those shown in Figure 3.
Tel que représenté à la figure 3, l'élément (1) peut comporter un support (10) sur lequel sont surmoulées les faces interne (5) et externe (6).As represented in FIG. 3, the element (1) can comprise a support (10) on which are molded the inner (5) and outer (6).
De cette manière, il est possible d'utiliser des matériaux différents pour réaliser ces trois couches.In this way, it is possible to use different materials to make these three layers.
Avantageusement, on peut choisir un matériau pour former les faces interne (5) et externe (6) qui comportent une rigidité supérieure à celle du matériau utilisé pour le support (10).Advantageously, one can choose a material to form the internal faces (5) and outer (6) which have a rigidity greater than that of the material used for the support (10).
Cet agencement permet en effet de fournir à l'élément (1) une certaine élasticité pour s'adapter à différents diamètres de barres (2).This arrangement makes it possible to provide the element (1) with a degree of elasticity to accommodate different bar diameters (2).
De la même manière, il est alors possible de réaliser la face interne (5) de l'élément (1) dans un matériau qui présente des caractéristiques anti-friction intéressantes, tel du téflon notamment. In the same way, it is then possible to make the internal face (5) of the element (1) in a material having anti-friction characteristics interesting, such Teflon particular.
Il ressort de ce qui précède qu'un élément conforme à l'invention présente de multiples avantages, parmi lesquels on peut citer :
- il permet de s'adapter à différents diamètres de barres ;
- il ne nécessite aucune confection ou manipulation particulières pour le mettre en place à l'intérieur d'une patte ;
- il est utilisé de manière totalement indépendante ;
- il s'adapte à tout type de pattes et notamment les pattes comportant des noeuds ;
- il présente une très faible surface de frottement répartie dans une zone relativement importante.
- it makes it possible to adapt to different diameters of bars;
- it does not require any special manufacture or manipulation to put it in place inside a leg;
- it is used completely independently;
- it adapts to all types of legs and in particular the legs with knots;
- it has a very small friction surface distributed in a relatively large area.
