Abstract

In order to assemble three elements at about 90 DEG with respect to each other, such as a leg 1 and two seat cross-members 2, 3, the first 1 is made to comprise two mortices 1a, 1b which intersect each other, the second 2 is made to comprise a short tenon 2a with a narrower median extension 2b, whilst a tenon 3a which is also short, but securely fastened to an extension 3b which has a notch 3c cut out of its middle is made on the third one 3. During assembly the main portion of the tenons 2a, 3a stops just at the intersection of the two mortices 1a, 1b, whilst the extensions 2b, 3b snugly fit into each other, thus providing a safe rigid assembly without play.

Description

La présente invention a pour objet un système d'assemblage propre à resoudre le problème que pose l'assemblage les uns avec les autres de trois éléments de meubles ou analogues, orients suivant des angles qui ne s'écartent pas par trop de 900. The present invention relates to an assembly system capable of solving the problem posed by the assembly with each other of three pieces of furniture or the like, oriented at angles which do not deviate by too much from 900.

On rencontre notamment ce problème dans le cas des sièges tels que tabourets, chaises ou analogues, faits d'un cadre dans lequel la surface portante est encadrée par des traverses, longerons, assises ou analogues qui viennent se fixer à des pieds ou montants. Dans les angles d'un tel cadre, deux traverses ou autres qui font l'une avec l'autre un angle droit ou presque, doivent être assemblées aux pieds de façon à constituer avec ceux-ci un ensemble présentant par lui-même une grande rigidite. Or, on dispose en fait de peu d'espace pour assurer cet assemblage en quelque sorte croisé, de sorte que les solutions proposées jusqu'ici ont généralement comporte soit l'inconvénient d'être peu resistantes, soit celui de conduire à des réalisations compliquées, encombrantes et coûteuses. This problem is encountered in particular in the case of seats such as stools, chairs or the like, made of a frame in which the bearing surface is framed by crosspieces, side members, seats or the like which are fixed to feet or uprights. In the corners of such a frame, two crosspieces or the like which form a right angle with each other or almost, must be assembled with the feet so as to constitute with them an assembly presenting by itself a large rigidity. However, there is in fact little space to ensure this sort of crossover assembly, so that the solutions proposed so far generally have either the disadvantage of being not very resistant, or that of leading to complicated embodiments , bulky and expensive.

L'invention vise au contraire à permettre de réaliser un système d'assemblage simple, de faible encombrement, robuste et peu coûteux. The invention, on the contrary, aims to make it possible to produce a simple assembly system, compact, robust and inexpensive.

Conformément a l'invention, l'un des trois (liements a assembler, par exemple un pied ou montant de siège pour fixer les idées, est creusé de deux mortaises qui se croisent à son intérieur, tandis que l'un des deux autres est solidaire d'un tenon propre à être engage dans l'une de celles-ci, ce tenon, prévu relativement court par rapport à la profondeur de la mortaise intEressée, comportant un prolongement dont la hauteur est réduite dans le haut et dans le bas, et que le troisième élément est solidaire de son cate d'un tenon lui aussi relativement court destine à s'engager dans l'autre mortaise et dont le prolongement est découpé dans le milieu de sa hauteur d'une entaille de largeur égale a celle du prolongement du tenon du second élément, le tout étant dimensionné de façon telle que lorsque les tenons de ces second et troisième élément sont enfonces à fond dans les mortaises respectives du premier, le prolongement du tenon du second vienne s'engager sans jeu dans l'entaille du prolongement du troisibme. According to the invention, one of the three (links to assemble, for example a foot or seat post to fix ideas, is hollowed out of two mortises which intersect inside it, while one of the other two is integral with a stud suitable for being engaged in one of these, this stud, provided relatively short in relation to the depth of the mortise being interested, comprising an extension whose height is reduced at the top and at the bottom, and that the third element is integral with its cate of a tenon which is also relatively short intended to engage in the other mortise and the extension of which is cut in the middle of its height by a notch of width equal to that of the extension of the tenon of the second element, the whole being dimensioned in such a way that when the tenons of these second and third element are fully inserted into the respective mortises of the first, the extension of the tenon of the second comes to engage without play in the prolo hack third change.

Te dessin annexe, donne à titre d'exemple, permettra de mieux comprendre l'invention, les caractéristiques qu'elle pressente et les avantages qu'elle est susceptible de procurer
Fig. 1 est une vue en perspective montrant les extrémités de deux traverses, longerons ou assises d'un cadre de siège avec les tenons dont ils sont pourvus présentés en face des mortaises correspondan tes creusées dans le pied ou montant avec lequel l'assemblage doit être réalisé.
The accompanying drawing, given by way of example, will allow a better understanding of the invention, the characteristics which it senses and the advantages which it is likely to provide.
Fig. 1 is a perspective view showing the ends of two crosspieces, side members or seats of a seat frame with the tenons which they are provided presented opposite the corresponding mortises hollowed out in the foot or amount with which the assembly is to be carried out .

Fig. 2 est une coupe verticale par le plan moyen du second élément à l'état assemblé (élément de droite en fig. 1). Fig. 2 is a vertical section through the mean plane of the second element in the assembled state (right element in FIG. 1).

Fig. 3 est une coupe suivant III-III (fig. 2) et dans laquelle le plan de coupe de fig. 2 a été indiqué en II-II. Fig. 3 is a section along III-III (fig. 2) and in which the section plane of fig. 2 was indicated in II-II.

En fig. 1, l'on aperçoit en 1 le haut de l'un des montants ou pieds d'un siege tel qu'un tabouret ou chaise. On a supposé que ce pied s'arretait au niveau de la surface du siège, comme cela est le cas pour un tabouret ou pour l'avant d'une chaise. Les références 2 et 3 de signent respectivement la traverse longitudinale et la traverse transversale ou assise qui correspondent au montant 1. I1 convient d'assembler ces trois éléments de façon rigide et sûre. In fig. 1, we see in 1 the top of one of the uprights or feet of a seat such as a stool or chair. It has been assumed that this leg stops at the seat surface, as is the case for a stool or the front of a chair. References 2 and 3 sign respectively the longitudinal cross and the transverse or seat cross which correspond to the amount 1. I1 should assemble these three elements rigidly and securely.

Le pied ou montant 1 est creusé de deux mortaises la et lb allongées dans le sens vertical et orientées horizontalement suivant le grand axe et le petit axe de sa section. Comme le montre bien fig. 3, ces deux mortaises s'intersectent; la première s'arrêtant au point d'intersection alors que la seconde se prolonge quelque peu au-delà de celui-ci. La traverse 2 porte en bout un tenon 2a de longueur réduite, solidaire d'un prolongement 2b de moindre hauteur (ou largeur, si l'on se place dans le plan moyen de la traverse). The foot or upright 1 is hollowed out of two mortises la and lb elongated in the vertical direction and oriented horizontally along the major axis and the minor axis of its section. As shown in fig. 3, these two mortises intersect; the first stops at the point of intersection while the second extends somewhat beyond it. The cross-member 2 carries at the end a tenon 2a of reduced length, integral with an extension 2b of lesser height (or width, if one places oneself in the middle plane of the cross-member).

Comme montré, ce prolongement 2b est centre par rapport à l'axe du tenon, si bien qu'il définit ainsi deux épaulements intermediaires 2c. As shown, this extension 2b is center relative to the axis of the post, so that it thus defines two intermediate shoulders 2c.

De son côté, le tenon 3a de l'assise 3, prévu lui aussi de longueur -relativesent faible, comporte également un prolongement se présentant sous la forme de deux dents 3b entourant une entaille 3c.For its part, the post 3a of the seat 3, also provided of short relative length, also has an extension in the form of two teeth 3b surrounding a notch 3c.

On notera que le grand axe de la section rectangulaire du montant I est oriente suivant l'axe longitudinal de la traverse 2. It will be noted that the major axis of the rectangular section of the upright I is oriented along the longitudinal axis of the crosspiece 2.

Les dimensions respectives des mortaises et des tenons sont telles que lorsque le tenon 2a de la traverse 2 est engagé à fond dans la mortaise la (position de fig. 2 et 3), sa partie principale, c'est-8-dire celle située en arrière du prolongement 2b, s'arrête juste dans le plan où cette première mortaise débouche dans la seconde lb, le prolongement 2b s'étendant légèrement au-delà de cette seconde mortaise lb. De son catie, le tenon 3a de l'assise 3 est suffisamment court pour s'arrêter juste dans le plan où la seconde mortaise débouche dans la première, tandis que les dents 3b s'entendent jusqu'au fond. The respective dimensions of the mortises and the tenons are such that when the tenon 2a of the crosspiece 2 is fully engaged in the mortise the (position of fig. 2 and 3), its main part, that is to say that located behind the extension 2b, stops just in the plane where this first mortise opens into the second lb, the extension 2b extending slightly beyond this second mortise lb. From its catie, the post 3a of the seat 3 is short enough to stop just in the plane where the second mortise opens into the first, while the teeth 3b are heard to the bottom.

Enfin, la largeur ou hauteur de l'entaille 3c est telle que ces dents viennent enserrer sans jeu le prolongement 2b du tenon 2a de la traverse 2.Finally, the width or height of the notch 3c is such that these teeth come to grip the extension 2b of the stud 2a of the crosspiece 2 without any play.

On comprend que dans ces conditions l'on réalise ainsi un assemblage absolument sûr, d'encombrement réduit et qui garantit au tabouret ou siège une remarquable stabilité. It is understood that under these conditions an absolutely safe assembly is thus achieved, of reduced bulk and which guarantees remarkable stability to the stool or seat.

I1 doit d'ailleurs être entendu que la description qui précède n' a été donnée qu'à titre d'exemple et qu'elle ne limite nullement le domaine de l'invention dont on ne sortirait pas en remplaçant les détails d'exécution décrits par tous autres équivalents. On comprend notamment que le pied ou montant 1 pourrait s'enlever bien au-dessus de l'assemblage comme cela est le cas pour les montants arrière des chaises. La traverse 2 et l'assise 3 pourraient être orientées l'une par rapport à l'autre à un angle quelque peu différent de 900. It should moreover be understood that the above description has been given only by way of example and that it in no way limits the field of the invention from which one would not depart by replacing the execution details described by all other equivalents. It is understood in particular that the foot or upright 1 could be removed well above the assembly as is the case for the rear uprights of the chairs. The cross member 2 and the seat 3 could be oriented relative to each other at an angle somewhat different from 900.

On conçoit encore que l'invention est applicable dans tous les cas où l'on se trouve devant ce même problème d'assembler deux éléments tels que 2 et 3, avec un troisième tel que 1 contre les faces latérales duquel ils viennent s'abouter.  It is also understood that the invention is applicable in all cases where we are faced with this same problem of assembling two elements such as 2 and 3, with a third such as 1 against the side faces of which they come to abut .
