Abstract
Description
L'invention concerne la fixation entre eux de profilés metalliques du genre de ceux que comportent des pièces de mobilier, par exemple des bâtis d'armoires, de tables et analogues.The invention relates to the fixing between them of metal profiles of the kind that include pieces of furniture, for example cabinet frames, tables and the like.
Des pieds ou montants sont fixés à la plupart des meubles métalliques soit par soudure, soit pas vissage d'une platine, elle-meme soudée à chaque montant ou pied.Feet or uprights are attached to most metal furniture either by welding or by screwing a plate, itself welded to each upright or foot.
Ces réalisations présentent des inconvenients, en particulier lorsque les pieds sont soudés, ils sont indemontables. Lorsqu ils comportent une platine vissée au meuble, il est nécessaire de disposer d'outils pour la mise en place et le serrage des vis et écrous.These embodiments have drawbacks, in particular when the feet are welded, they cannot be dismantled. When they include a plate screwed to the cabinet, it is necessary to have tools for the installation and tightening of the screws and nuts.
L'invention crée un nouveau dispositif de fixation et de verrouillage qui élimine toute nécessité de disposer d'outils de montage et qui permet d'assurer une liaison sans jeu extrêmement fiable entre un pied ou montant et un profilé constituant un longeron ou une traverse du bâti d'un meuble.The invention creates a new fixing and locking device which eliminates the need for mounting tools and which ensures an extremely reliable backlash-free connection between a foot or upright and a profile constituting a beam or a cross member of the built of furniture.
Conformément à l'invention, le dispositif de fixation et de verrouillage de deux profiles, en particulier pour pieds de meubles est caractérisé en ce qu'un premier profile, faisant partie du meuble, présente un fond et des bords tombés s'eten- dant sur une partie au moins de sa longueur, des lumières étant prévues dans lesdits bords tombés pour coïncider partiellement avec des trous sensiblement circulaires prévus dans un pied ou montant, lesdits trous et lumières étant traversés par une clé présentant un segment de section non circulaire dont la rotation dans lesdites lumières et trous provoque le serrage de l'extrémité du pied ou montant contre le fond du profilé à bords tombés. According to the invention, the device for fixing and locking two profiles, in particular for furniture legs, is characterized in that a first profile, forming part of the furniture, has a bottom and falling edges extending over at least part of its length, openings being provided in said fallen edges to partially coincide with substantially circular holes provided in a foot or upright, said holes and openings being traversed by a key having a segment of non-circular section whose rotation in said openings and holes causes the end of the foot or clamping against the bottom of the profile with fallen edges to be clamped.
Diverses autres caractéristiques de l'invention ressortent d'ailleurs de la description détaillee qui suit.Various other characteristics of the invention will also emerge from the detailed description which follows.
Des formes de réalisation de l'objet de l'invention sont représentées, à titre d'exemples non limitatifs, aux dessins annexés.Embodiments of the subject of the invention are shown, by way of nonlimiting examples, in the accompanying drawings.
La fig. 1 est une perspective partielle de profiles destinés à être fixés entre eux par le dispositif de l'invention.Fig. 1 is a partial perspective of profiles intended to be fixed together by the device of the invention.
Les fig. 2 a 4 sont des élévations partielles de face illustrant différentes positions caractéristiques du dispositif de fixation de la fig. 1.Figs. 2 to 4 are partial front elevations illustrating different characteristic positions of the fixing device of FIG. 1.
La fig. 5 est une perspective d'une clé que comporte le dispositif des figures precedentes.Fig. 5 is a perspective of a key that includes the device of the preceding figures.
La fig. 6 est une coupe-élévation schématique illustrant une caractéristique supplémentaire du dispositif de fixation de l'invention.Fig. 6 is a schematic sectional elevation illustrating an additional characteristic of the fixing device of the invention.
Bien que l'invention s'applique â des profilés de formes diverses, elle trouve une application particulièrement appro priee à la fixation d'un pied ou montant 1 à l'intérieur d'un profilé 2 en U, constituant une partie d'un cadre ou d'un châssis d'un meuble, par exemple une armoire, une table ou analogue.Although the invention applies to profiles of various shapes, it finds a particularly suitable application for fixing a foot or upright 1 inside a U-shaped profile 2, constituting part of a frame or chassis of a piece of furniture, for example a cabinet, a table or the like.
Dans l'exemple illustré, le pied 1 est de section circulaire.In the example illustrated, the foot 1 is of circular section.
L'invention s'appliquerait de la même façon si ce pied présentait une section polygonale, par exemple carrée. De façon analogue, le profilé 2 pourrait présenter une autre forme pour autant qu'il comporterait un fond 3 et des bords tombés 4, 5, s'étendant sur une partie au moins de la longueur. The invention would apply in the same way if this foot had a polygonal section, for example square. Similarly, the profile 2 could have another shape as long as it has a bottom 3 and fallen edges 4, 5, extending over at least part of the length.
Des lumières 6 et 7 à fond sensiblement plan sont pratiquées dans les bords tombés 4, 5 du profilé 2, ces lumières s'étendant jusqu'à intersecter les lignes de pliage 8, 9 formées entre le fond 3 et les bords tombés 4, 5. De cette manière, le fond 3 est plan au moins sur l'étendue séparant l'extremi- té supérieure des deux lumières 6, 7.Lights 6 and 7 with a substantially planar bottom are formed in the fallen edges 4, 5 of the profile 2, these lights extending until they intersect the fold lines 8, 9 formed between the bottom 3 and the fallen edges 4, 5 In this way, the bottom 3 is plane at least over the extent separating the upper end of the two openings 6, 7.
Le montant 1 présente de son côté deux trous 10, 11 diamétralement opposés, qui sont percés à une distance de l'extremite 12 supérieure à la partie la plus basse des lumières 6, 7.The upright 1 has two diametrically opposite holes 10, 11 which are drilled at a distance from the end 12 greater than the lowest part of the openings 6, 7.
De cette façon, comme le montre la fig. 2, lorsque le pied 1 est mis en place dans le profile 2, de manière que l'extremi- té 12 se trouve à proximité ou contre le fond 3, les trous 10, 11 coïncident en partie avec le fond des lumières 6, 7 mais s'étendent neanmoins en dessous de la partie basse 13 des lumières 6, 7.In this way, as shown in fig. 2, when the foot 1 is placed in the profile 2, so that the end 12 is near or against the bottom 3, the holes 10, 11 partly coincide with the bottom of the lights 6, 7 but nevertheless extend below the lower part 13 of the lights 6, 7.
Le dispositif comporte une clé 14 comprenant un segment 15 de section non circulaire, par exemple sensiblement ovale ou rectangulaire à petits côtés arrondis, comme illustré par le dessin. Un second segment 16 constitue un levier qui s'entend sensiblement à 90 par rapport au segment 15 et présente en section une forme quelconque.The device comprises a key 14 comprising a segment 15 of non-circular section, for example substantially oval or rectangular with small rounded sides, as illustrated by the drawing. A second segment 16 constitutes a lever which is understood to be substantially 90 with respect to segment 15 and has any shape in section.
Le grand axe du premier segment de forme ovale présente une longueur sensiblement égale au diamètre des trous 10, 11 qui sont circulaires, afin que ledit segment 15 puisse être enga gé dans les lumières 6, 7 et les trous 10, 11 avec un leger jeu lorsque ces lumières et trous coïncident partiellement, comme illustré par la fig. 1.The major axis of the first oval-shaped segment has a length substantially equal to the diameter of the holes 10, 11 which are circular, so that said segment 15 can be engaged in the slots 6, 7 and the holes 10, 11 with a slight clearance. when these lights and holes partially coincide, as illustrated in fig. 1.
La clé 14, mise en place dans le profilé 2 et le pied 1, est ensuite tournée suivant la flèche fl ainsi que l'illustre la fig. 3, ce qui a pour effet d'appliquer l'extrémité 12 du pied contre le fond 3 du profilé 2.The key 14, placed in the profile 2 and the foot 1, is then turned along the arrow f1 as illustrated in FIG. 3, which has the effect of applying the end 12 of the foot against the bottom 3 of the profile 2.
Le mouvement de pivotement de la clé 14 est poursuivi jusqu'à ce que le grand axe de l'ovale, formé par le segment 15, soit sensiblement aligne avec l'axe du montant 1. De cette manière, l'extrémité 12 du montant 1 est très fortement serrée contre la partie plane du dessous du fond 3 sans qu'il puisse exister aucun jeu entre le profilé 2 et le montant 1 qui est ainsi verrouillé et maintenu sous contrainte dans ledit profile 2.The pivotal movement of the key 14 is continued until the major axis of the oval, formed by the segment 15, is substantially aligned with the axis of the upright 1. In this way, the end 12 of the upright 1 is very tightly pressed against the flat part of the bottom of the bottom 3 without there being any play between the profile 2 and the upright 1 which is thus locked and kept under stress in said profile 2.
Selon la fig. 5, le second segment 16 de la clé 14 est court, sa longueur n'étant pas suffisante pour délimiter un bras de levier suffisant pour permettre le mouvement de pivotement décrit dans ce qui précède.According to fig. 5, the second segment 16 of the key 14 is short, its length not being sufficient to define a lever arm sufficient to allow the pivoting movement described in the foregoing.
Dans ce cas, il est prévu un levier tubulaire 17 d'une longueur appropriée qui est enfilé sur le second segment 16 et qui permet d'assurer facilement le pivotement de la clé 14, le levier tubulaire étant ensuite retiré par coulissement pour être utilisé à la commande d'autres clés 14 assurant la fixation d'autres montants 1 dans le profilé 2.In this case, a tubular lever 17 of an appropriate length is provided which is threaded onto the second segment 16 and which makes it possible to easily pivot the key 14, the tubular lever then being withdrawn by sliding to be used for the control of other keys 14 ensuring the fixing of other uprights 1 in the profile 2.
La fig. 6 illustre un developpement de l'invention selon lequel au moins un des trous îîa du montant 1 présente une ouverture non circulaire delimitant une bute 18. Dans ce cas, lorsque la clé 14 est suffisamment tournée pour assurer le verrouillage du montant 1 contre le fond 3 du profilé, le segment 15 vient en appui contre la butée 18 sans pouvoir être pivoté davantage qui correspond à la position optimale du segment 15.Fig. 6 illustrates a development of the invention according to which at least one of the holes of the upright 1 has a non-circular opening delimiting a stop 18. In this case, when the key 14 is turned enough to lock the upright 1 against the bottom 3 of the profile, the segment 15 comes to bear against the stop 18 without being able to be pivoted further which corresponds to the optimal position of the segment 15.
I1 resulte de cette réalisation qu'aucune précaution particu hère n'est à prendre pour manoeuvrer la cle 14 jusqu'à la position la plus appropriée pour assurer le verrouillage du montant 1 dans le profilé 2. It follows from this embodiment that no particular precaution is to be taken to operate the key 14 to the most appropriate position for locking the upright 1 in the profile 2.
L'invention n'est pas limitée aux exemples de réalisation représentés et décrits en détail, car diverses modifications peuvent y être apportées sans sortir de son cadre. The invention is not limited to the embodiments shown and described in detail, because various modifications can be made thereto without going beyond its scope.
