Abstract
Description
La présente invention a pour objet une lame pour la réalisation de portes de meubles, rideaux, volets ou similaires.The present invention relates to a blade for the production of furniture doors, curtains, shutters or the like.
Il est très pratique d'équiper les meubles et notamment les meubles de bureaux de portes à rideaux, c'est-à-dire de portes comportant une pluralité de lames articulées les unes sur les autres, et susceptibles, soit d'être situées dans un même plan en position fermée, soit de subir un enroulement en partie basse ou en partie haute du meuble pour dégager l'ouverture centrale, ou encore en partie basse et en partie haute. L'intérêt d'un tel agencement réside dans le fait qu'en position ouverte, la ou les portes ne débordent pas du meuble, ce qui procure un gain de place, et permet, en période de travail, de les laisser en position ouverte sans que celles-ci ne constituent une gêne.It is very practical to equip the furniture and in particular the office furniture with curtain doors, that is to say doors having a plurality of blades hinged on each other, and likely either to be located in the same plane in the closed position, either to undergo a winding in the lower part or in the upper part of the cabinet to release the central opening, or else in the lower part and in the upper part. The advantage of such an arrangement lies in the fact that in the open position, the door or doors do not project beyond the piece of furniture, which saves space, and makes it possible, during the working period, to leave them in the open position without these constituting an embarrassment.
Un tel meuble est par exemple conforme à celui représenté à la figure 1 du desin schématique annexé, représentant une armoire 2 comportant une porte réalisée à partir de deux panneaux, respectivement supérieur 3 et inférieur 4, se fermant dans un plan horizontal à mi-hauteur, chacun des panneaux étant constitué de lames 5 articulées les unes sur les autres.Such a piece of furniture is, for example, in conformity with that shown in FIG. 1 of the appended schematic drawing, representing a
Les lames entrant dans la constitution de telles portes peuvent être réalisées de différentes façons. Selon une première possibilité, il s'agit de lames en bois collées sur une bande textile formant support et permettant l'articulation de l'ensemble. Une autre possibilité consiste à utiliser des lames métalliques réunies les unes aux autres par des axes, ou encore des lames en matière plastique conformées de manière telle qu'un de leurs bords présente une languette arrondie, tandis que leur bord opposé comporte une rainure de forme complémentaire. L'engagement d'une languette d'une lame dans la rainure d'une lame adjacente assure à la fois la tenue et l'articulation des deux lames l'une relativement à l'autre.The blades used in the constitution of such doors can be produced in different ways. According to a first possibility, these are wooden blades glued to a textile strip forming a support and allowing the assembly of the assembly. Another possibility is to use metal blades joined to each other by axes, or plastic blades shaped so that one of their edges has a rounded tongue, while their opposite edge has a shaped groove complementary. The engagement of a tongue of a blade in the groove of an adjacent blade ensures both the holding and the articulation of the two blades relative to each other.
Si les lames en matière synthétique donnent entière satisfaction, en ce qui concerne leur mode de fonctionnement, et notamment l'absence de bruit lors de la manoeuvre des portes, elles présentent l'inconvénient d'être d'un prix de revient très élevé, en raison du coût des matières premières les constituant.If the plastic blades are entirely satisfactory, as regards their mode of operation, and in particular the absence of noise during the operation of the doors, they have the disadvantage of being of a very high cost price, because of the cost of the raw materials they are made of
De telles lames sont également utilisées pour d'autres applications telles que la réalisation de rideaux ou de volets.Such blades are also used for other applications such as the production of curtains or shutters.
Il est donc plus intéressant financièrement pour une personne disposant d'un matériel permettant de travailler les tôles, de réaliser les portes à partir de lames métalliques.It is therefore more interesting financially for a person having a material allowing to work the sheets, to realize the doors from metal blades.
Le brevet US 3.437.126 concerne une lame pour porte de meuble, du type énoncé dans le préambule de la revendication 1. Cette lame est réalisée à partir d'un profilé métallique ouvert, de section en U, dont l'aile supérieure horizontale présente un prolongement vertical vers le haut, et dont l'aile inférieure horizontale est prolongée par des crochets en forme d'équerres, aptes à pénétrer chacun dans une lumière ménagée dans le profilé situé immédiatement endessous, à la jonction de l'aile supérieure et du prolongement vertical de celle-ci.US Patent 3,437,126 relates to a blade for a furniture door, of the type set out in the preamble of claim 1. This blade is produced from an open metal profile, of U-shaped section, the horizontal upper wing of which has a vertical extension upwards, the horizontal lower wing of which is extended by square-shaped hooks, each capable of penetrating into a lumen formed in the profile located immediately below, at the junction of the upper wing and the vertical extension thereof.
Ces lames présentent l'inconvénient de posséder des parties en saillie à l'intérieur du meuble, susceptibles d'accrocher les éléments contenus dans celui-ci, et en outre de laisser un certain jeu vertical entre les lames, engendrant un bruit important en période de manoeuvre du rideau, lors des «tombées» successives des lames les unes sur les autres.These blades have the drawback of having protruding parts inside the cabinet, capable of catching the elements contained therein, and in addition of leaving a certain vertical clearance between the blades, generating significant noise during the period. for operating the curtain, during successive "falls" of the blades on top of each other.
Le brevet FR 1.511.068 décrit un volet à lames métalliques assemblées et articulées les unes sur les autres. Chaque lame est constituée par une bande métallique repliée sur elle-même de façon que les grandes faces soient jointives sur la presque totalité de la hauteur, avec ménagement de crochets et d'ouvertures correspondantes ménagés respectivement à proximité des bords inférieur et supérieur de la lame. Cette structure n'assure pas une bonne tenue verticale des lames les unes relativement aux autres, ce qui se traduit par un bruit de fonctionnement important.Patent FR 1,511,068 describes a shutter with metal blades assembled and articulated one on the other. Each blade is formed by a metal band folded back on itself so that the large faces are contiguous over almost the entire height, with provision for hooks and corresponding openings formed respectively near the lower and upper edges of the blade. . This structure does not ensure good vertical holding of the blades relative to each other, which results in a significant operating noise.
Le brevet FR. 1 213 885 concerne un volet à lames tubulaires en matière synthétique, assemblées les unes aux autres par des crochets indépendants situés sensiblement dans le plan médian longitudinal des lames.The FR patent. 1,213,885 relates to a shutter with tubular blades of synthetic material, assembled to each other by independent hooks situated substantially in the longitudinal median plane of the blades.
Les crochets ou agrafes d'assemblage font saillie de l'une des petites faces d'une lame. Dans la face en regard de la lame adjacente sont ménagées des lumières longitudinales, dont le nombre correspond au nombre de crochets,chaque lumière ayant une longueur égale à celle d'une agrafe, et étant décalée par rapport à celle-ci d'une longueur sensiblement égale à celle de la zone de liaison entre une agrafe et la lame. Les agrafes d'une lame sont engagées dans les fentes correspondantes d'une lame adjacente, les deux lames ayant subi un décalage axial, après quoi les deux lames sont ramenées en alignement afin que la partie en débord de chaque agrafe soit à l'intérieur de la lame adjacente et derrière la paroi de celle-ci.The hooks or assembly staples protrude from one of the small faces of a blade. In the opposite face of the adjacent blade are formed longitudinal slots, the number of which corresponds to the number of hooks, each slot having a length equal to that of a staple, and being offset with respect to the latter by a length substantially equal to that of the connection zone between a staple and the blade. The staples of a blade are engaged in the corresponding slots of an adjacent blade, the two blades having undergone an axial shift, after which the two blades are brought back into alignment so that the projecting part of each staple is inside of the adjacent blade and behind the wall thereof.
Ces lames sont coûteuses à réaliser et à assembler, et présentent en outre l'inconvénient de subir un déplacement axial les unes relativement aux autres, lors des manoeuvres du volet.These blades are costly to produce and assemble, and also have the drawback of undergoing axial displacement relative to one another, during the maneuvers of the shutter.
La présente invention vise à fournir une lame métallique pour la réalisation de portes, remédiant à ces inconvénients.The present invention aims to provide a metal blade for the production of doors, overcoming these drawbacks.
Cette lame est du type comprenant, d'une part, des languettes en forme d'agrafes faisant saillie sur la petite face de la lame formant le bord inférieur et d'autrepart, des lumières longitudinales ménagées sur le bord supérieur de ladite lame et qui sont aptes à recevoir les languettes en forme d'agrafes précitées de la lame située immédiatement au-dessus, afin de réaliser l'accrochage et l'articulation des deux lames considérées, selon l'invention, cette lame forme un élément tubulaire de section sensiblement rectangulaire, les deux bords parallèles de la bande métallique à partir de laquelle elle est réalisée étant jointifs et étant situés au niveau d'un angle de la lame tournée vers l'intérieur du meuble, les languettes en forme d'agrafes étant constituées par le prolongement de la grade face de la lame tournée vers l'intérieur du meuble, les lumières longitudinales étant ménagées dans l'autre petite face de la lame correspondant à son bord supérieur, à proximité de la grande face de la lame prolongée par les agrafes, chaque lumière ayant une longueur égale à celle d'une agrafe et étant décalée par rapport à celle-ci du côté de la zone de liaison entre l'agrafe et la lame, d'une longueur sensiblement égale à la longueur de ladite zone.This blade is of the type comprising, on the one hand, tabs in the form of staples projecting from the small face of the blade forming the lower edge and, on the other hand, longitudinal slots formed on the upper edge of said blade and which are suitable for receiving the aforementioned clips in the form of staples from the blade situated immediately above, in order to attach and articulate the two blades considered, according to the invention, this blade forms a tubular element of substantially section rectangular, the two parallel edges of the metal strip from which it is made being joined and being located at an angle of the blade facing the interior of the cabinet, the tabs in the form of staples being formed by the extension of the face grade of the blade facing the interior of the cabinet, the longitudinal slots being formed in the other small face of the blade corresponding to its upper edge, near the large face of the blade extended by the staples, each lumen having a length equal to that of a staple and being offset with respect thereto ci on the side of the connection zone between the staple and the blade, of a length substantially equal to the length of said zone.
D'un point de vue pratique, les agrafes d'une lame sont engagées dans les fentes en regard d'une lame adjacente, les deux lames ayant un léger décalage axial, après quoi les deux lames sont ramenées en alignement, de telle sorte que la partie en débord de chaque agrafe soit à l'intérieur de la lame adjacente, et derrière la paroi de celle-ci. Cette solution assure la tenue des lames les unes relativement aux autres, tout en permettant leur articulation en vue de leur escamotage en position ouverte de la porte, sans nécessiter de pièces intermédiaires.From a practical point of view, the staples of one blade are engaged in the slots opposite an adjacent blade, the two blades having a slight axial offset, after which the two blades are brought back into alignment, so that the protruding part of each clip is inside the adjacent blade, and behind the wall thereof. This solution ensures the holding of the blades relative to each other, while allowing them to be articulated with a view to their retraction in the open position of the door, without requiring any intermediate parts.
Le montage ainsi réalisé assure une très bonne tenue des lames les unes relativement aux autres, évitant qu'elles se heurtent lors de la manoeuvre du rideau qu'elles constituent. En outre le fait que les lames soient tubulaires assure une excellente présentation de celles-ci, sur leurs deux faces, sans aucune partie en saillie risquant d'accrocher les dossiers ou autres objets contenus dans le meuble équipé de ce rideau, et permet le ménagement d'un volume creux pouvant recevoir des mousses ignifuges et/ou insonori- santes.The assembly thus produced ensures very good resistance of the blades relative to each other, preventing them from colliding during the operation of the curtain that they constitute. In addition the fact that the blades are tubular ensures an excellent presentation of these, on their two faces, without any projecting part risking to hang the files or other objects contained in the piece of furniture equipped with this curtain, and allows the sparing of a hollow volume capable of receiving fireproof and / or soundproofing foams.
Un procédé de fabrication de cette lame consiste à réaliser tout d'abord la coupe à la longueur de la bande métallique destinée à la formation d'une lame, à réaliser par poinçonnage, grugeage et lumièrage les languettes en forme d'agrafes au niveau de l'un des bords de la bande, les lumières orientées longitudinalement à la bande, et les découpes d'extrémité, puis à procéder à la mise en forme de la lame par plusieurs emboutissages successifs, assurant la formation de plis longitudinaux dont l'un est ménagé à proximité de la série de lumières, et qui sont réalisés de façon que les deux bords paralléles de la bande métalique à partir de laquele la lame est réalisée soient jointifs et situés à un angle de ladite lame.A method of manufacturing this blade consists in first making the cut to the length of the metal strip intended for the formation of a blade, in making by punching, notching and lumièrage the tabs in the form of staples at one of the edges of the strip, the lights oriented longitudinally to the strip, and the end cutouts, then proceed to the shaping of the blade by several successive stampings, ensuring the formation of longitudinal folds, one of which is arranged near the series of lights, and which are made so that the two parallel edges of the metal strip from which the blade is made are contiguous and located at an angle to said blade.
