Description

La présente invention concerne une armoire à rideau(x) comprenant au moins un rideau vertical coulissant formé avec une lame terminale verticale définissant un bord mobile du rideau. Ce genre d'armoire comprend en général deux rideaux identiques par symétrie miroir. Les deux rideaux sont déplaçables en coulissement en éloignement l'un de l'autre pour ouvrir l'armoire et en rapprochement l'un de l'autre pour fermer l'armoire. Les rideaux sont conventionnellement formés à partir de lames longitudinales verticales qui sont articulées les unes par rapport aux autres. La lame terminale verticale constitue la dernière lame du rideau et forme par conséquent le bord mobile qui définit l'ouverture d'accès à l'intérieur de l'armoire. En général, le rideau est pourvu d'une poignée qui est conventionnellement disposée au niveau des lames terminales. La présente invention concerne par conséquent plus particulièrement le domaine des armoires de rangement à rideau(x), très fréquemment utilisées comme mobilier de bureau.The present invention relates to a curtain cabinet (x) comprising at least one vertical sliding curtain formed with a vertical end plate defining a movable edge of the curtain. This type of cabinet generally comprises two identical curtains by mirror symmetry. The two curtains are slidably movable away from each other to open the cabinet and move closer to each other to close the cabinet. The curtains are conventionally formed from vertical longitudinal blades which are hinged to each other. The vertical terminal blade is the last blade of the curtain and therefore forms the movable edge which defines the access opening to the interior of the cabinet. In general, the curtain is provided with a handle which is conventionally arranged at the terminal blades. The present invention therefore relates more particularly to the field of curtain storage cabinets (x), very frequently used as office furniture.

Les rideaux de ce type d'armoire comprennent un bord supérieur et un bord inférieur engagés dans des rails de glissement fixés à la structure de l'armoire. Par conséquent, chaque lame du rideau comprend une extrémité supérieure et une extrémité inférieure engagées dans ces rails de glissement. Il en est de même pour la lame terminale dont les extrémités supérieure et inférieure sont généralement pourvues de patins de glissement engagés dans les rails de glissement. Du fait de la gravité, le patin de glissement situé à l'extrémité inférieure de la lame terminale vient en contact de glissement avec le fond du rail inférieur.The curtains of this type of cabinet comprise an upper edge and a lower edge engaged in sliding rails fixed to the structure of the cabinet. Therefore, each blade of the curtain comprises an upper end and a lower end engaged in these sliding rails. It is the same for the end plate whose upper and lower ends are generally provided with sliding pads engaged in the sliding rails. Due to the gravity, the sliding shoe located at the lower end of the end plate comes into sliding contact with the bottom of the lower rail.

En général, les lames terminales sont réalisées en métal ou en matière plastique. Les patins de glissement sont généralement réalisés en matière plastique moulée. Ainsi, les patins de glissement sont montés et fixés au niveau des deux extrémités de la lame terminale. La fixation des patins de glissement peut être réalisée par tout moyen, comme par engagement en force, encliquetage, ou vissage. D'autre part, les rails de glissement sont en général réalisés en métal ou en matière plastique. Les patins de glissement assurent ainsi un bon coulissement de la lame terminale à l'intérieur des rails.In general, the terminal blades are made of metal or plastic. The sliding pads are generally made of molded plastic. Thus, the sliding pads are mounted and fixed at both ends of the terminal blade. The fixing of the sliding pads can be carried out by any means, such as by engagement with force, latching, or screwing. On the other hand, the sliding rails are generally made of metal or plastic. The sliding pads thus ensure a good sliding of the terminal blade inside the rails.

Cependant, du fait que les patins de glissement sont généralement réalisés en matière plastique, et qu'ils doivent être fixés aux extrémités de la lame terminale, il arrive que les patins soient endommagés, ce qui nuit au bon fonctionnement de l'armoire. Il faut en effet savoir que ce type d'armoires à rideau est souvent utilisé avec peu de ménagement du fait de son usage purement fonctionnel. Ainsi, les patins de glissement sont soumis à de rudes conditions qui peuvent engendrer leur rupture. D'autre part, étant donné que les patins sont des pièces séparées qui doivent être fabriquées séparément par injection moulage, ils présentent un prix de revient relativement significatif. De surcroît, il faut procéder à une opération de montage des patins sur les extrémités de la lame terminale, ce qui prend du temps et engendre un coût de montage.However, because the sliding pads are generally made of plastic material, and they must be fixed to the ends of the end plate, it happens that the pads are damaged, which affects the proper functioning of the cabinet. It must be known that this type of curtain cabinet is often used with little care because of its purely functional use. Thus, the sliding pads are subjected to harsh conditions that can cause them to break. On the other hand, since the pads are separate pieces that must be manufactured separately by injection molding, they have a relatively significant cost. In addition, it is necessary to proceed to a mounting operation of the pads on the ends of the terminal blade, which takes time and generates a cost of assembly.

Dans l'art antérieur, on connaît le document FR 2 836 350 qui décrit un rideau dont le bord inférieur coulisse dans une glissière métallique en forme de V. Par ailleurs, le document DE 20 2004 004871 U1 décrit un rideau métallique qui coulisse dans des rails de guidage métalliques.In the prior art, the document is known FR 2,836,350 which describes a curtain whose lower edge slides in a V-shaped metal slide. DE 20 2004 004871 U1 discloses a metal curtain which slides in metal guide rails.

La présente invention a pour but de remédier aux inconvénients précités de l'art antérieur en définissant une lame terminale verticale à patin de glissement dont la robustesse est améliorée et dont la mise en oeuvre est facilitée, et ceci à moindre coût.The object of the present invention is to overcome the aforementioned drawbacks of the prior art by defining a vertical slip-sliding end plate whose robustness is improved and whose implementation is facilitated, and this at a lower cost.

Pour atteindre ces buts, la présente invention propose une armoire à rideau selon la revendication 1.To achieve these objects, the present invention provides a curtain cabinet according to claim 1.

Selon une caractéristique intéressante de l'invention, le patin s'étend sensiblement perpendiculairement à la direction longitudinale verticale de la lame et forme ainsi une sorte de cornière à angle droit. Avantageusement, le patin est obtenu par pliage. Le métal, et plus particulièrement la tôle métallique, est un matériau particulièrement avantageux pour la réalisation de la lame terminale à patin de glissement intégré.According to an advantageous characteristic of the invention, the pad extends substantially perpendicularly to the vertical longitudinal direction of the blade and thus forms a kind of right angle bracket. Advantageously, the pad is obtained by folding. Metal, and more particularly sheet metal metal, is a particularly advantageous material for the realization of the end plate with integrated sliding shoe.

Selon un autre aspect de l'invention, le patin se connecte à la lame au niveau d'une arête sensiblement droite, l'arête étant pourvue d'au moins une nervure de renforcement pour stabiliser l'orientation du patin par rapport à la lame.According to another aspect of the invention, the pad connects to the blade at a substantially straight edge, the edge being provided with at least one reinforcing rib to stabilize the orientation of the pad relative to the blade. .

Avantageusement, le godron est réalisé de manière monobloc avec le patin. Selon un autre aspect, le godron peut présenter un profil arrondi. Avantageusement, le godron est obtenu par déformation locale du patin. Ceci est notamment le cas lorsque la lame terminale est réalisée en métal, et plus particulièrement à partir de tôle métallique.Advantageously, the gadroon is made integrally with the pad. In another aspect, the gadroon may have a rounded profile. Advantageously, the gadroon is obtained by local deformation of the pad. This is particularly the case when the terminal blade is made of metal, and more particularly from sheet metal.

Selon une autre caractéristique de l'invention permettant d'améliorer le glissement du rideau, le fond du rail présente un profil convexe dont la surface est avantageusement grenée. Ainsi, le ou les godrons arrondi(s) viennent en contact du profil convexe du fond du rail, ce qui réduit considérablement la surface de contact entre le patin et le rail. En outre, la surface grenée permet encore de réduire la surface de contact entre le patin et le fond du rail. Ainsi, le glissement du rideau dans les rails est considérablement amélioré.According to another characteristic of the invention for improving the sliding of the curtain, the bottom of the rail has a convex profile whose surface is advantageously grained. Thus, the rounded gadroon (s) come into contact with the convex profile of the bottom of the rail, which considerably reduces the contact surface between the pad and the rail. In addition, the grainy surface further reduces the contact area between the pad and the bottom of the rail. Thus, the sliding of the curtain in the rails is considerably improved.

L'invention sera maintenant plus amplement décrite en référence aux dessins joints, donnant à titre d'exemple non limitatif un mode de réalisation de l'invention.The invention will now be further described with reference to the accompanying drawings, giving by way of non-limiting example an embodiment of the invention.

  • La figure 1 est une vue de face d'une armoire à rideau conventionnelle incorporant l'invention,
  • La figure 2 est une vue très largement agrandie d'un détail de la figure 1,
  • Les figures 3a, 3b et 3c sont des vues en perspective d'une partie de lame terminale selon l'invention au cours de trois étapes successives de fabrication, et
  • La figure 4 est une vue en coupe transversale verticale à travers la partie inférieure d'une lame terminale selon l'invention engagée dans un rail inférieur.
In the figures:
  • The figure 1 is a front view of a conventional curtain cabinet incorporating the invention,
  • The figure 2 is a greatly enlarged view of a detail of the figure 1 ,
  • The Figures 3a, 3b and 3c are perspective views of a terminal blade portion according to the invention during three successive manufacturing steps, and
  • The figure 4 is a vertical cross-sectional view through the lower part of a terminal blade according to the invention engaged in a lower rail.

L'armoire à rideaux illustrée sur la figure 1 comprend des parois latérales verticales 11, un soubassement 12, ainsi qu'un chapeau 13. La structure fixe de l'armoire est en outre complétée par une face arrière (non représentée). Ces éléments de l'armoire peuvent être réalisés en métal, par exemple de la tôle métallique. La face avant de l'armoire est formée par deux rideaux 2 qui sont disposés sensiblement verticalement. Ces rideaux 2 sont réalisés à partir de lames verticales 20 qui sont fixées les unes aux autres de manière articulée. Ainsi, les rideaux 2 sont flexibles de sorte qu'ils peuvent s'enrouler le long des parois latérales 11, à l'intérieur de l'armoire. Avantageusement, la structure fixe de l'armoire est pourvue intérieurement de joues verticales qui s'étendent sensiblement parallèlement aux parois latérales 11. Les rideaux 2, lorsqu'on les déplace vers la position ouverte, viennent se loger entre les joues et les parois latérales 11. Les rideaux 2 s'enroulent alors sur eux-mêmes dans un rail de glissement présentant un chemin en épingle à cheveux. Les rideaux 2, outre leur lame articulée 20, comprennent également chacun une lame terminale verticale 21 qui constitue le bord du rideau. Les lames 21 sont destinées à venir en contact l'une de l'autre sur leur hauteur en position fermée, comme représenté sur la figure 1. Lorsque le rideau est ouvert, les lames terminales 21 définissent une partie du bord d'ouverture donnant accès à l'intérieur de l'armoire.The curtain cabinet shown on the figure 1 comprises vertical side walls 11, a base 12, and a cap 13. The fixed structure of the cabinet is further complemented by a rear face (not shown). These elements of the cabinet can be made of metal, for example sheet metal. The front face of the cabinet is formed by two curtains 2 which are arranged substantially vertically. These curtains 2 are made from vertical blades 20 which are fixed to each other in an articulated manner. Thus, the curtains 2 are flexible so that they can be wound along the side walls 11, inside the cabinet. Advantageously, the fixed structure of the cabinet is internally provided with vertical cheeks that extend substantially parallel to the side walls 11. The curtains 2, when moved to the open position, are housed between the cheeks and the side walls 11. The curtains 2 then wind themselves on a sliding rail with a hairpin path. The curtains 2, in addition to their articulated blade 20, also each comprise a vertical end plate 21 which constitutes the edge of the curtain. The blades 21 are intended to come into contact with each other on their height in the closed position, as shown in FIG. figure 1 . When the curtain is open, the terminal blades 21 define a part of the opening edge giving access to the interior of the cabinet.

Pour permettre le coulissement des rideaux 2, il est ainsi prévu un rail inférieur situé au niveau du soubassement 12 et un rail supérieur situé au niveau du chapeau 13. Ces rails de coulissement s'étendent jusqu'au niveau des parois latérales 11 pour permettre aux deux rideaux de se loger à l'intérieur de l'armoire, entre les joues internes susmentionnées et les parois 11. Pour permettre ce coulissement, les extrémités libres inférieures et supérieures des lames 20 et 21 sont engagées à l'intérieur de ces rails inférieurs et supérieurs respectifs. Ainsi, les extrémités inférieures 22 des deux lames terminales 21 sont engagées dans le rail inférieur 122 logées dans le soubassement 12, alors que les deux extrémités libres supérieures 23 des deux lames terminales 21 sont engagées dans le rail supérieur logé dans le chapeau 13. En se référant à la figure 2, on voit les extrémités inférieures des lames 20 engagées dans le rail inférieur 122. Du fait de la gravité, les extrémités inférieures des lames viennent en contact avec le fond 123 du rail 122. Le rail 122 est fixé sur une plaque de fond 121 qui fait partie du soubassement 12.To allow the sliding of the curtains 2, there is thus provided a lower rail located at the base 12 and an upper rail located at the cap 13. These sliding rails extend to the level of the side walls 11 to allow the two curtains to be housed inside the cabinet, between the aforementioned internal cheeks and the walls 11. To allow this sliding, the lower and upper free ends of the blades 20 and 21 are engaged inside these lower rails and respective superiors. Thus, the lower ends 22 of the two end plates 21 are engaged in the lower rail 122 housed in the base 12, while the two upper free ends 23 of the two end plates 21 are engaged in the upper rail housed in the cap 13. referring to the figure 2 the lower ends of the blades 20 engaged in the lower rail 122 are seen. Due to gravity, the lower ends of the blades come into contact with the bottom 123 of the rail 122. The rail 122 is fixed on a bottom plate 121 which is part of the bedrock 12.

Selon l'invention, les lames terminales 21, qui sont réalisées en métal, sont pourvues au niveau d'une ou de chacune de leurs extrémités libres 22 et/ou 23 d'un ou de deux patins de glissement 25 engagés à l'intérieur de son rail respectif inférieur et supérieur. Les extrémités inférieures 22 des lames terminales 21 sont de préférence pourvues de patins de glissement, alors que les extrémités supérieures 23 peuvent être dépourvues de patins de glissement. Toutefois, les patins de glissement aux deux extrémités des lames sont préférés. Selon l'invention, les patins de glissement 25 sont réalisés de manière monobloc par les lames terminales 21. En d'autres termes, c'est une partie intégrante de la lame 21 qui forme le patin de glissement 25. De préférence, chaque lame terminale 21 est pourvue de deux patins de glissement intégrés monobloc, de sorte que la lame avec ses patins ne forme qu'une seule pièce unique. De préférence, les lames terminales 21 sont réalisées par usinage de plaques de tôle métalliques, par exemple du fer, de l'acier ou de l'aluminium.According to the invention, the end plates 21, which are made of metal, are provided at one or each of their free ends 22 and / or 23 of one or two sliding pads 25 engaged inside. from its respective lower and upper rail. The lower ends 22 of the end plates 21 are preferably provided with sliding pads, while the ends upper 23 may be devoid of sliding pads. However, the sliding pads at both ends of the blades are preferred. According to the invention, the sliding pads 25 are made integrally by the end plates 21. In other words, it is an integral part of the blade 21 which forms the sliding pad 25. Preferably, each blade terminal 21 is provided with two integrally integrated sliding pads, so that the blade with its pads forms only one single piece. Preferably, the end plates 21 are made by machining sheet metal plates, for example iron, steel or aluminum.

On se réfèrera maintenant aux figures 3a, 3b et 3c pour expliquer de quelle manière on peut réaliser les patins de glissement des lames terminales 21 à partir d'une plaque de tôle métallique. Deux ou plusieurs lames terminales 21 peuvent être réalisées à partir d'un seul profilé métallique, comme on peut le voir sur les figures 3a et 3b. Le profilé métallique a été plié de manière appropriée afin de réaliser une âme centrale 210 qui va constituer la face frontale de la lame. D'autre part, cette âme 210 est bordée de part et d'autre par deux bords 211 et 212. Un des bords va servir à la fixation à une lame 20, alors que l'autre bord va constituer la tranche visible de la lame terminale destinée à venir en contact avec la tranche de l'autre lame terminale 21. Pour commencer, on découpe dans le profilé une fente F en forme de H. Deux brides symétriques par symétrie miroir se font ainsi face. Chaque bride est ensuite usinée, par exemple par déformation de matière, de manière à former par exemple deux godrons de glissement 251. On peut par exemple utiliser une technique de matriçage ou de poinçonnage pour obtenir ces godrons de glissement 251. Pour l'instant, les deux brides qui se font face s'étendent dans le même plan que l'âme 210. Une étape ultérieure consiste à replier ces brides, de manière à former les patins de glissement 25. Le pliage des brides s'effectue avec un angle sensiblement droit, de sorte que les patins 25 s'étendent alors perpendiculairement à l'âme 210, et plus généralement perpendiculairement à la direction longitudinale des lames terminales 21. Pour stabiliser l'orientation perpendiculaire des patins 25, on peut avantageusement former une ou plusieurs nervures de renforcement 252 au niveau de l'arête sensiblement rectiligne 253 qui relie le patin 25 à l'âme 210. Une fois les patins 25 ainsi obtenus, on peut couper le profilé métallique de manière à obtenir deux lames terminales distinctes, comme on peut le voir sur la figure 3c. Les godrons 251 des patins 25 forment un profil arrondi vers l'extérieur. La forme générale des godrons est sensiblement similaire à celle d'un grain de riz. On peut également remarquer que le bord du patin 25 est également arrondi, de manière à éliminer tout angle vif. Chaque patin peut être pourvu d'un seul godron formant un dôme arrondi.We will now refer to Figures 3a, 3b and 3c to explain how one can achieve the sliding pads of the terminal blades 21 from a sheet metal plate. Two or more end plates 21 can be made from a single metal profile, as can be seen in the Figures 3a and 3b . The metal section has been folded appropriately to produce a central core 210 which will constitute the front face of the blade. On the other hand, this core 210 is bordered on both sides by two edges 211 and 212. One of the edges will be used for attachment to a blade 20, while the other edge will constitute the visible edge of the blade terminal end to come into contact with the edge of the other terminal blade 21. To begin, is cut in the profile a slot F in the form of H. Two flanges symmetrical mirror symmetry are thus facing. Each flange is then machined, for example by deformation of material, so as to form, for example, two sliding flutes 251. For example, a punching or punching technique can be used to obtain these sliding fluting 251. For the moment, the two opposite flanges extend in the same plane as the core 210. A subsequent step consists of folding these flanges, so as to form the sliding pads 25. The folding of the flanges takes place at an angle substantially right, so the skids 25 then extend perpendicularly to the core 210, and more generally perpendicularly to the longitudinal direction of the end plates 21. To stabilize the perpendicular orientation of the pads 25, it is advantageous to form one or more reinforcing ribs 252 at the level of the substantially rectilinear edge 253 which connects the pad 25 to the web 210. Once the pads 25 thus obtained, the metal section can be cut so as to obtain two separate end plates, as can be seen on the figure 3c . The gadroons 251 of the pads 25 form a profile rounded outwards. The general shape of the gadroons is substantially similar to that of a grain of rice. It can also be noted that the edge of the pad 25 is also rounded, so as to eliminate any sharp angle. Each pad can be provided with a single godron forming a rounded dome.

Une fois inséré dans le rail 122, le patin 25 est disposé comme représenté sur la figure 4. Avantageusement, le fond 123 du rail 122 est réalisé avec un profil convexe qui vient en contact avec le ou les godrons 251. Ainsi, le contact du patin 25 avec le fond 123 du rail est extrêmement réduit, ce qui augmente les qualités de glissement du rideau à l'intérieur des rails. On peut même prévoir de réaliser le profil convexe du fond du rail 123 avec une qualité de surface grenée, afin de réduire encore davantage le contact entre le rail et le patin. En se référant à la figure 4, on peut voir que le patin 25 s'étend à partir de l'extrémité inférieure de la lame 21 vers l'intérieur de l'armoire, c'est-à-dire en éloignement du soubassement 12. On peut également noter que le rail 122 est fixé à la plaque de fond 121 à l'aide d'une tête d'encliquetage 124 engagée dans une ouverture appropriée ménagée dans la plaque 121.Once inserted into the rail 122, the shoe 25 is arranged as shown on the figure 4 . Advantageously, the bottom 123 of the rail 122 is made with a convex profile which comes into contact with the godrons 251. Thus, the contact of the pad 25 with the bottom 123 of the rail is extremely reduced, which increases the sliding qualities of the rail. curtain inside the rails. One can even provide to achieve the convex profile of the bottom of the rail 123 with a grainy surface quality, to further reduce the contact between the rail and the pad. Referring to the figure 4 it can be seen that the shoe 25 extends from the lower end of the blade 21 towards the inside of the cabinet, that is to say away from the base 12. It can also be noted that the rail 122 is attached to the bottom plate 121 by means of a detent head 124 engaged in a suitable opening in the plate 121.

Grâce à l'invention, on obtient des lames terminales très faciles à réaliser, d'un coût de revient faible et incorporant en outre des patins de glissement particulièrement robustes.Thanks to the invention, one obtains terminal blades very easy to achieve, a low cost and incorporating further slip skids particularly robust.
