Abstract

The invention concerns a device for assembling at least two elements to be made integral forming between them a fixed non-straight angle characterised in that it comprises two opposing pieces (3 and 4), one (3) substantially concave designed to be pressed outside the angle formed by the elements (1 and 2) and the other (4) substantially convex designed to be pressed inside said angle. Said two pieces (3 and 4) are to be directly pressed against the elements to be assembled with an assembling member (5-26) at least to bring together said two parts (3 and 4) passing through a space (15) separating the edges of the elements (1 and 2) to be located parallel, so as to clamp said elements (1 and 2) between the two parts (3 and 4), without direct contact between them, to form a finished assembly capable of receiving an optional additional element (30).

Description

Dispositif d'assemblage, notamment pour meubles Assembly device, especially for furniture
La présente invention concerne l'assemblage de pièces entre elles, essentiellement des éléments, afin de constituer des structures telles que des meubles mais compte tenu de son caractère universel, l'invention ne se limite pas aux meubles mais à tout ensemble formé par l'assemblage de parties faisant entre elles un angle non plat.The present invention relates to the assembly of parts together, essentially elements, in order to constitute structures such as furniture but taking into account its universal character, the invention is not limited to furniture but to any assembly formed by the assembly of parts forming a non-flat angle between them.
Traditionnellement, la fixation relativement l'une à l'autre de pièces en bois se fait par interpénétration d'éléments découpés : feuillures, emboîtement de languettes notamment en queue d'aronde, etc., ce qui suppose un ou plusieurs usinages des arêtes préalablement à leur assemblage et à leur immobilisation par collage, et la qualité de l'objet final dépend en grande partie de cet usinage préalable.Traditionally, the fixing relative to one another of wooden pieces is done by interpenetration of cut elements: rebates, interlocking of tongues in particular in dovetail, etc., which supposes one or more machining of the edges beforehand to their assembly and immobilization by gluing, and the quality of the final object depends largely on this prior machining.
On comprend que cette opération soit coûteuse en raison de la main d'oeuvre, de l'outillage et du temps nécessaires à sa réalisation.It is understood that this operation is costly due to the manpower, the tools and the time necessary to carry it out.
On a donc cherché prioritairement à simplifier l'usinage en le ramenant au strict minimum nécessaire à l'emploi d'organes de fixation distincts et rapportés : vis. inserts. noyaux excentrés, et autres systèmes bien connus de l'Homme de Métier.Priority has therefore been given to simplifying the machining by reducing it to the strict minimum necessary for the use of separate and attached fixing members: screws. inserts. eccentric cores, and other systems well known to those skilled in the art.
Les différences entre les systèmes connus résident essentiellement dans les organes d'assemblage, car les pièces doivent toujours être mises en contact l'une avec l'autre, ce qui suppose encore un minimum d'usinage. On connaît par ailleurs des assemblages qui prévoient que les pièces assemblées sont écartées l'une de l'autre mais lorsque la structure est terminée, l'écartement reste visible et participe à son esthétique.The differences between the known systems essentially lie in the assembly members, since the parts must always be brought into contact with each other, which again requires a minimum of machining. It also knows assemblies which provide that the assembled parts are spaced apart from one another but when the structure is completed, the distance is still visible and is involved in its aesthetics.
D'autres solutions existent pour masquer cet écartement, mais alors l'assemblage ne concerne plus deux pièces mais trois. Pour situer l'Etat de la Technique, on peut citer les documents suivants : • DE 802 014 qui décrit un système d'assemblage simultané de deux éléments 6 et d'un montant 1, au moyen de deux pièces 8 et 9 dont l'une 9. s'appuie sur les deux éléments 6 et l'autre 8 sur un retour 2 du montant 1. Cet assemblage ne permet ni d'assembler les deux éléments 6 seulement, ni de dissocier le montant 1 , indépendamment des éléments 6. Il s'agit donc bien d'un assemblage de trois pièces selon les trois directions de l'espace. • GB 2 214 595 qui décrit un assemblage de deux éléments 1 et 2 au moyen d'une pièce 10 et de deux vis. Un élément de protection angulaire 13 en matière synthétique est engagé sur les extrémités des éléments 1 et 2 avant serrage complet des vis.Other solutions exist to mask this spacing, but then the assembly no longer concerns two parts but three. To locate the state of the technique include the following: • DE 802 014 describes a system of simultaneous assembly of two elements 6 and $ 1, with two parts 8 and 9 whose 9. a relies on the two elements 6 and the other 8 of a return amount of 2 1. This assembly does not allow to assemble the two elements 6 only, or decouple the level 1 independently members 6. It is therefore indeed an assembly of three parts in the three directions of space. • GB 2 214 595 which describes an assembly of two elements 1 and 2 by means of a part 10 and two screws. An angular protective element 13 made of synthetic material is engaged on the ends of the elements 1 and 2 before the screws are fully tightened.
L'élément 13 est assujetti à la pièce 10 par des vis 26 qui sont serrées en même temps que les vis qui fixent la pièce 10 aux éléments 1 et 2.The element 13 is secured to the part 10 by screws 26 which are tightened at the same time as the screws which fix the part 10 to the elements 1 and 2.
La présente invention propose une solution nouvelle selon laquelle aucun usinage préalable n'est nécessaire pour les pièces à assembler mais reste toujours possible pour améliorer, embellir, anoblir la structure terminée, l'essentiel de l'usinage devant être pratiqué sur des organes d'assemblage tout à fait originaux. II est ainsi possible de réaliser des ensembles de pièces indépendantes (ou « kits ») présentées à plat, selon un encombrement minimum, l'assemblage étant très simple car il se fait par paires de éléments seulement, un troisième élément éventuel pouvant être ajouté indépendamment de l'assemblage des éléments.The present invention proposes a new solution according to which no preliminary machining is necessary for the parts to be assembled but is always possible to improve, embellish, ennoble the finished structure, most of the machining having to be practiced on organs of completely original assembly. It is thus possible to produce sets of independent parts (or “kits”) presented flat, according to a minimum space requirement, the assembly being very simple because it is done by pairs of elements only, a third possible element which can be added independently. of the assembly of the elements.
A cette fin, l'invention a pour objet un dispositif d'assemblage d'au moins deux éléments devant être rendus solidaires en faisant entre eux un angle fixe non plat, caractérisé en ce qu'il comprend deux pièces antagonistes, l'une essentiellement concave destinée à être appliquée à l'extérieur de l'angle que font les éléments et l'autre essentiellement convexe destinée à être appliquée à l'intérieur dudit angle, ces deux pièces étant appliquées directement contre les éléments à assembler un organe d'assemblage au moins devant réunir ces deux pièces en passant par un espace qui sépare les arêtes des éléments devant être situées parallèlement, afin de serrer lesdits éléments entre les deux pièces, sans contact direct entre eux, pour former un ensemble fini susceptible de recevoir un élément supplémentaire éventuel. Selon d'autres caractéristiques de l'invention : => chacune des deux pièces présente des faces d'appui qui forment entre elles un angle égal à celui des éléments après solidarisation, chaque face d'appui de la pièce extérieure étant parallèle à une face d'appui de la pièce intérieure en étant séparées l'une de l'autre d'une distance égale à l'épaisseur des éléments ; => les éléments ayant une épaisseur non négligeable, la pièce extérieure présente deux faces divergentes solidaires mais non jointives, dont la largeur est coordonnée à l'épaisseur des éléments, les faces d'appui étant formées par deux ailes situées aux extrémités des faces divergentes ; => l'une des pièces est destinée à être fixée aux éléments ;To this end, the subject of the invention is a device for assembling at least two elements which must be made integral by making a fixed, non-flat angle between them, characterized in that it comprises two opposing parts, one essentially concave intended to be applied outside the angle made by the elements and the other essentially convex intended to be applied inside said angle, these two parts being applied directly against the elements to be assembled an assembly member at least having to join these two parts through a space which separates the edges of the elements to be located in parallel, in order to clamp said elements between the two parts, without direct contact between them, to form a finished assembly capable of receiving an additional element possible. According to other characteristics of the invention: => each of the two parts has bearing faces which form between them an angle equal to that of the elements after joining, each bearing face of the external part being parallel to a face supporting the interior part, being separated from each other by a distance equal to the thickness of the elements; => the elements having a non negligible thickness, the external part presents two divergent faces interdependent but not contiguous, whose width is coordinated with the thickness of the elements, the bearing faces being formed by two wings located at the ends of the divergent faces ; => one of the parts is intended to be fixed to the elements;

=î la pièce extérieure constitue un montant d'un meuble, notamment un pied de siège ; = la pièce extérieure présente une rainure destinée à recevoir par coulissement longitudinal une partie de l'organe d'assemblage plus large que l'ouverture de la rainure ; => des éléments de solidarisation sont prévus entre les éléments et au moins l'une des pièces ; => les éléments de solidarisation sont constitués pas des picots appartenant à l'une au moins des pièces et devant pénétrer dans la matière constitutive des éléments ; = les éléments de solidarisation sont constitués par au moins une languette, éventuellement collée, introduite dans un logement d'un élément et/ou de la pièce extérieure ; = le dispositif comprend un cache placé devant les pièces extérieures afin de les masquer ; => des moyens sont prévus pour immobiliser le cache mis en place ; => le cache est rendu solidaire d'au moins une pièce extérieure, notamment par fixation ou en étant monobloc avec la ou lesdites pièces extérieures ; => les moyens pour immobiliser le cache mis en place sont constitués par des lamelles prévues sur la pièce extérieure et destinées à pénétrer dans des rainures du cache ; => les moyens pour immobiliser le cache mis en place sont constitués par une rainure longitudinale axiale du cache, destinée à recevoir par coulissement longitudinal une partie de l'organe d'assemblage plus large que l'ouverture de la rainure.

En se reportant au dessin, on voit qu'un dispositif d'assemblage conforme à l'invention est destiné à assembler deux éléments angulairement décalés 1 et 2 tels que des éléments, des longerons, traverses et similaires, et comprend deux pièces antagonistes 3 et 4 devant être appliquées directement contre les éléments 1 et 2, respectivement à l'extérieur et à l'intérieur de l'angle que forment lesdits éléments 1 et 2. L'extérieur de cet angle est essentiellement convexe alors qu'au contraire l'intérieur de ce même angle est essentiellement concave, raison pour laquelle on qualifie de « concave » la pièce 3 qui se place à l'extérieur de l'angle et de « convexe » la pièce 4 qui se place à l'intérieur dudit angle. Après mise en place, les deux pièces 3 et 4 doivent être réunies directement l'une à l'autre et sollicitées en permanence vers leur rapprochement afin de maintenir énergiquement serrés les éléments assemblés angulairement 1 et 2. Sur les figures 1 à 3, l'assemblage conforme à l'invention est représenté dans sa forme la plus fruste, à savoir que es pièces 3 et 4 sont en bois et leur assemblage est réalisé au moyen d'une vis 5 de type connu.Referring to the drawing, it can be seen that an assembly device according to the invention is intended to assemble two angularly offset elements 1 and 2 such as elements, beams, crosspieces and the like, and comprises two opposing parts 3 and 4 to be applied directly against elements 1 and 2, respectively outside and inside the angle formed by said elements 1 and 2. The outside of this angle is essentially convex whereas, on the contrary, the inside of this same angle is essentially concave, which is why the part 3 which is placed outside the angle is called "concave". "Convex" the part 4 which is placed inside said angle. After installation, the two parts 3 and 4 must be joined directly to each other and permanently urged towards their bringing together in order to keep energetically tight the angularly assembled elements 1 and 2. In FIGS. 1 to 3, l 'assembly according to the invention is shown in its most crude form, namely that the parts 3 and 4 are made of wood and their assembly is carried out by means of a screw 5 of known type.
Pour que les éléments 1 et 2 soient immobilisés par le simple serrage des pièces 3 et 4, la pièce 3 présente deux ailes 6 et 7 contre lesquelles se placent directement les éléments 1 et 2. tandis que la pièce 4 a des appuis latéraux 8 et 9 situés dans des plans parallèles à celui des ailes 6 et 7 donnant à la pièce 4 un contour en trapèze, de telle sorte que les éléments 1 et 2 sont emprisonnés entre les ailes 6-7 et les appuis 8-9, sans aucune pièce intermédiaire.So that the elements 1 and 2 are immobilized by simply tightening the parts 3 and 4, the part 3 has two wings 6 and 7 against which the elements 1 and 2 are placed directly, while the part 4 has lateral supports 8 and 9 located in planes parallel to that of the wings 6 and 7 giving the part 4 a trapezoid outline, so that the elements 1 and 2 are trapped between the wings 6-7 and the supports 8-9, without any part intermediate.
On a choisi de représenter le cas d'assemblage le plus fréquent, à savoir l'assemblage des éléments 1 et 2 à angle droit, mais l'invention s'applique bien évidemment à tous les angles possibles (sauf l'angle plat à 180°) sous réserve d'adapter en conséquence les parties actives des pièces 3 et 4.We have chosen to represent the most frequent assembly case, namely the assembly of elements 1 and 2 at right angles, but the invention obviously applies to all possible angles (except the flat angle at 180 °) subject to adapting accordingly the active parts of parts 3 and 4.
Cela étant rappelé, on observe que la pièce 3 présente des plans 10 et 1 1 formant entre eux un angle de 90° et que les ailes 6 et 7 ont des faces internes 12 et 13 perpendiculaires aux plans 10 et 1 1 et formant donc aussi entre elles un angle de 90°. Un plan 10-11 et une face interne 12-13 forment ensemble deux côtés d'une feuillure dans laquelle se loge une extrémité d'un élément 1-2. Les petites faces d'extrémité des éléments 1 et 2 viennent en butée contre les plans 10 et 11 et les faces extérieures de ces éléments 1 et 2 se placent directement contre les faces internes 12 et 13 des ailes 6 et 7. On remarque que la force d'assemblage est dirigée selon l'axe de la vis 5 qui est situé selon la bissectrice de l'angle des éléments 1 et 2. Le serrage de ces éléments 1 et 2 se fait de part et d'autre de cette bissectrice comme la double résultante venant de l'orientation des faces internes 12 et 13 d'une part et des appuis 8 et 9 d'autre part. Cette structure laisse subsister un espace 15 entre les arêtes des éléments 1 et 2, de sorte que ces éléments 1 et 2 peuvent être absolument standards, sans aucun usinage, puisque non seulement ils ne sont pas assemblés directement mais qu'ils ne sont même pas mis au contact l'un de l'autre. Ils peuvent être réalisés en toute matière : bois, métal, carton, matière synthétique, etc. On peut prévoir de solidariser les éléments 1 et 2 et au moins l'une des pièces 3 et 4. Cela peut être obtenu, lorsque les éléments 1 et 2 ont une épaisseur substantielle (en particulier quand ils sont en bois) au moyen de languettes (non représentées) situées sur les arêtes des éléments 1 et 2 et devant pénétrer dans des rainures de la pièce 3. Bien entendu, le contraire est également possible : languettes solidaires de la pièce 3 et devant pénétrer dans des rainures des éléments 1 et 2. Comme cela est connue en soi, on peut aussi prévoir des rainures à la fois sur les arêtes des éléments 1 et 2 et sur la pièce 3, des languettes distinctes étant rapportées dans deux rainures en regard et éventuellement collées. Sur les figures 1 à 3, on a représenté un mode de réalisation selon lequel l'assemblage des éléments 1 et 2 se fait au moyen de deux couples de pièces 3-4 mais on comprend qu'un seul couple peut être suffisant ou qu'au contraire il est nécessaire d'en prévoir un plus grand nombre, selon la hauteur des éléments 1 et 2. Mais, selon un mode de réalisation particulier, la pièce 3 peut être au moins aussi haute que les éléments 1 et 2, auquel cas on peut qualifier cette pièce de profilé, lequel peut être fait en toute matière convenable, selon l'application envisagée. Il est possible de prévoir une seule pièce (ou profilé) 3 et une seule pièce antagoniste 4 de même longueur mais on peut également associer plusieurs pièces 4 et une seule longue pièce 3. La pièce 3 peut être beaucoup plus haute que les éléments 1 et 2, notamment pour constituer des montants, ou pieds, les éléments 1 et 2 devenant des traverses. L'assemblage des figures 1 à 3 est représenté comme s'adaptant à des éléments 1 et 2 en bois, les pièces 3 et 4 étant elles-mêmes en bois. Du fait même de ce matériau, ces pièces 3 et 4 doivent avoir une épaisseur minimum, et donc une certaine surface extérieure qui leur permet de servir de base d'appui à un panneau (non représenté) placé et fixé sur ces pièces, à la manière d'un plateau de table ou d'une assise de siège. En supposant que les éléments 1 et 2 sont dans des plans verticaux (comme cela est visible sur les figures 2 et 3), le élément peut être disposé horizontalement. L'invention permet ainsi de réaliser des sièges, des tables ou analogues, les pieds étant formés par des pièces 3, le élément supérieur pouvant se placer à l'intérieur du contour des éléments 1-2, à l'extérieur de ce contour ou dépasser nettement ce contour, comme cela est bien connu en soi.This being recalled, it is observed that the part 3 has planes 10 and 1 1 forming between them an angle of 90 ° and that the wings 6 and 7 have internal faces 12 and 13 perpendicular to the planes 10 and 1 1 and therefore also forming between them an angle of 90 °. A plane 10-11 and an internal face 12-13 together form two sides of a rebate in which is housed one end of an element 1-2. The small end faces of the elements 1 and 2 abut against the planes 10 and 11 and the external faces of these elements 1 and 2 are placed directly against the internal faces 12 and 13 of the wings 6 and 7. It is noted that the assembly force is directed along the axis of the screw 5 which is located along the bisector of the angle of the elements 1 and 2. The tightening of these elements 1 and 2 is done on either side of this bisector as the resulting double coming from the orientation of the internal faces 12 and 13 on the one hand and of the supports 8 and 9 on the other hand. This structure leaves a space 15 between the edges of elements 1 and 2, so that these elements 1 and 2 can be absolutely standard, without any machining, since not only are they not assembled directly but they are not even put in contact with each other. They can be made of any material: wood, metal, cardboard, synthetic material, etc. Provision may be made to secure the elements 1 and 2 and at least one of the parts 3 and 4. This can be obtained when the elements 1 and 2 have a substantial thickness (in particular when they are made of wood) by means of tongues. (not shown) located on the edges of elements 1 and 2 and having to penetrate into grooves in part 3. Of course, the opposite is also possible: tongues integral with part 3 and having to penetrate in grooves of elements 1 and 2 As is known per se, it is also possible to provide grooves both on the edges of the elements 1 and 2 and on the part 3, separate tongues being attached in two facing grooves and possibly glued. In FIGS. 1 to 3, an embodiment is shown according to which the assembly of elements 1 and 2 is done by means of two pairs of parts 3-4 but it is understood that a single couple may be sufficient or that on the contrary it is necessary to provide a larger number, depending on the height of the elements 1 and 2. But, according to a particular embodiment, the part 3 can be at least as high as the elements 1 and 2, in which case we can qualify this profile piece, which can be made of any suitable material, depending on the intended application. It is possible to provide a single piece (or section) 3 and a single opposing piece 4 of the same length, but it is also possible to combine several pieces 4 and a single long piece 3. The piece 3 can be much higher than the elements 1 and 2, in particular for constituting uprights, or feet, the elements 1 and 2 becoming crosspieces. The assembly of Figures 1 to 3 is shown as adapting to elements 1 and 2 of wood, the parts 3 and 4 being themselves of wood. By the very fact of this material, these parts 3 and 4 must have a minimum thickness, and therefore a certain external surface which allows them to serve as a support base for a panel (not shown) placed and fixed on these parts, to the like a table top or a seat. Assuming that the elements 1 and 2 are in vertical planes (as can be seen in Figures 2 and 3), the element can be arranged horizontally. The invention thus makes it possible to produce seats, tables or the like, the feet being formed by parts 3, the upper element being able to be placed inside the outline of elements 1-2, outside this outline or clearly exceed this outline, as is well known in itself.
La figure 4 représente une variante de réalisation de l'invention selon laquelle les pièces d'assemblage 3 et 4 sont réalisées en métal, ce qui les affranchit des nécessités d'épaisseur provenant de la nature du bois choisi pour l'exemple des figures 1 à 3. Mais ayant les mêmes fonctions, on retrouve sur la figure 4 des parties communes aux figures 1 à 3, ces parties communes portant les mêmes références et ne nécessitant pas une nouvelle description détaillée.FIG. 4 represents an alternative embodiment of the invention according to which the connecting pieces 3 and 4 are made of metal, which frees them from the need for thickness originating from the nature of the wood chosen for the example of FIGS. 1 to 3. But having the same functions, we find in FIG. 4 common parts to FIGS. 1 to 3, these common parts bearing the same references and not requiring a new detailed description.
En revanche, une différence essentielle provient du fait que l'on ne peut pas utiliser une vis à bois 5 et que les pièces 3 et 4 étant en métal, il faut prévoir lors de leur fabrication des passages pour au moins un boulon.On the other hand, an essential difference comes from the fact that one cannot use a wood screw 5 and that the parts 3 and 4 being made of metal, it is necessary to envisage during their manufacture passages for at least one bolt.
Ces passages sont des lumières oblongues 20 permettant de placer une tige filetée traversante 21 sans qu'il soit nécessaire d'aligner rigoureusement les deux pièces 3 et 4, l'ensemble étant serré au moyen d'un écrou 22 engagée sur l'extrémité de la tige 21. Lorsque les éléments 1 et 2 sont en un matériau relativement tendre tel que du bois, on peut prévoir des picots 25 sur les plans 10 et 11 de la pièce 3, ainsi que sur les appuis latéraux 8 et 9 de la pièce 4, afin que le serrage provoque la pénétration des picots 25 dans le bois des éléments 1 et 2 pour éviter tout glissement accidentel des pièces d'assemblage. La figure 5 représente une autre variante selon laquelle la pièce 3 est un simple étrier double en acier, présentant un œil central pour le passage de la tige filetée 21.These passages are oblong slots 20 making it possible to place a through threaded rod 21 without the need to rigorously align the two parts 3 and 4, the assembly being tightened by means of a nut 22 engaged on the end of the rod 21. When the elements 1 and 2 are made of a relatively soft material such as wood, pins 25 can be provided on the planes 10 and 11 of the part 3, as well as on the lateral supports 8 and 9 of the part 4, so that the tightening causes the pins 25 to penetrate into the wood of the elements 1 and 2 to prevent any accidental sliding of the assembly parts. FIG. 5 represents another variant according to which the part 3 is a simple double steel stirrup, having a central eye for the passage of the threaded rod 21.
Les extrémités libres de la pièce 3 peuvent être recourbées pour présenter des pointes effilées 26 devant pénétrer dans le matériau des éléments 1 et 2, comme les picots 25, afin d'empêcher le glissement accidentel des pièces d'assemblage. Les figures 4 et 5 montrent l'extérieur de l'angle d'assemblage et l'on peut constater que les pièces d'assemblage 3 sont visibles et peuvent nuire à l'esthétique de la structure, surtout lorsqu'il s'agit d'un meuble. Bien entendu, on peut délibérément laisser les pièces d'assemblage 3 visibles en leur donnant un minimum de caractère esthétique, mais une autre solution présente de nombreux avantages : ajouter un profilé qui dissimule les pièces d'assemblage 3 et contribue à une excellente finition de la structure. Sur la figure 6, on voit que les pièces 3 et 4 sont du type de celles représentées sur la figure 4 mais qu'elles sont assemblées par une tige filetée 26 ayant une tête 27 particulière, à savoir qu'elle dépasse extérieurement le diamètre de la tige 26 elle-même. Un cache 30 est disposé à l'extérieur de la pièce 3 pour la recouvrir et la masquer, ce cache 30 présentant une rainure longitudinale 31 à entrée plus étroite, de sorte que cette rainure a une section coordonnée au profil de la tige 26 et de sa tête 27.The free ends of the part 3 can be curved to present tapered points 26 which must penetrate into the material of the elements 1 and 2, such as the pins 25, in order to prevent accidental sliding of the assembly parts. Figures 4 and 5 show the outside of the assembly angle and we can see that the assembly parts 3 are visible and can affect the aesthetics of the structure, especially when it comes to 'furniture. Of course, we can deliberately leave the assembly parts 3 visible by giving them a minimum of aesthetic character, but another solution has many advantages: add a profile which conceals the assembly parts 3 and contributes to an excellent finish of the structure. In FIG. 6, it can be seen that the parts 3 and 4 are of the type of those shown in FIG. 4 but that they are assembled by a threaded rod 26 having a particular head 27, namely that it externally exceeds the diameter of the rod 26 itself. A cover 30 is arranged outside of the part 3 to cover and hide it, this cover 30 having a longitudinal groove 31 with a narrower entry, so that this groove has a section coordinated with the profile of the rod 26 and his head 27.
Ainsi, lors du serrage des pièces 3 et 4 au moyen d'un écrou 28 engagé sur la tige filetée 26, la tête 27 bute intérieurement contre l'entrée étroite de la rainure 31 et applique fortement le cache 30 contre la pièce 3 et celle-ci contre les éléments 1 et 2. Le cache 30 est donc immobilisé lors de l'assemblage et reste solidaire de la pièce 3 et, donc, de la pièce 4 et des éléments 1 et 2.Thus, during the tightening of parts 3 and 4 by means of a nut 28 engaged on the threaded rod 26, the head 27 abuts internally against the narrow entry of the groove 31 and strongly applies the cover 30 against the part 3 and that -this against elements 1 and 2. The cover 30 is therefore immobilized during assembly and remains integral with part 3 and, therefore, with part 4 and elements 1 and 2.
On donne au cache 30 la section voulue pour parfaire l'aspect de la structure, compte tenu du matériau dans lequel on réalise ce cache30 (métal, matière synthétique, bois, etc.).The cover 30 is given the desired section to perfect the appearance of the structure, taking into account the material from which this cover 30 is made (metal, synthetic material, wood, etc.).
Le cache 30 peut avoir une longueur relativement importante, de sorte que l'on peut le nommer « profilé », terme que l'on utilisera dans ce qui suit.The cover 30 can have a relatively large length, so that it can be called "profiled", a term which will be used in the following.
Sur cette même figure 6, on a représenté deux nervures de raidissage 41 et 42 qui arc- boutent les appuis latéraux 8 et 9 de la pièce 4 et rendent celle-ci plus résistante aux efforts de serrage des éléments 1 et 2 contre les faces internes des ailes 6 et 7 de la pièce 3. On a également représenté un trou 43 dans chacun des appuis latéraux 8 et 9, afin de pouvoir y introduire une vis (non représentée) destinée à pénétrer dans l'élément 1-2 correspondant pour parfaire, à titre subsidiaire, l'immobilisation de la pièce 4 (et donc de la pièce 3 aussi) par rapport aux éléments 1 et 2, après que l'assemblage proprement dit ait été achevé. Cette fixation peut rendre inutile la présence de picots 25. La figure 7 représente une variante du mode de réalisation de la figure 6 qui reprend l'essentiel de ses composants avec les mêmes références, et qui diffère de ce mode de réalisation par le fait que la tige filetée 26 comprend, en plus de la tête 27 de plus fort diamètre et de forme tronconique, un épaulement 29 qui prend appui directement sur la pièce 3.In this same FIG. 6, two stiffening ribs 41 and 42 have been shown which brace the lateral supports 8 and 9 of the part 4 and make it more resistant to the clamping forces of the elements 1 and 2 against the internal faces wings 6 and 7 of the part 3. A hole 43 has also been shown in each of the lateral supports 8 and 9, in order to be able to introduce therein a screw (not shown) intended to penetrate into the corresponding element 1-2 to perfect , in the alternative, the immobilization of part 4 (and therefore of part 3 also) with respect to elements 1 and 2, after the assembly proper has been completed. This fixing can make the presence of pins 25 unnecessary. FIG. 7 represents a variant of the embodiment of FIG. 6 which contains most of its components with the same references, and which differs from this embodiment by the fact that the threaded rod 26 comprises, in addition to the head 27 of larger diameter and of frustoconical shape, a shoulder 29 which bears directly on the part 3.
Ainsi, le serrage de la pièce 3 ne se fait pas exclusivement par le profilé 30, comme dans le cas de la figure 6, mais en plus, simultanément, par la tige filetée 26 dont l'épaulement 29 est au contact direct de la pièce 3. La tête 27 tronconique est en appui sur les flancs obliques de la rainure 31, c'est-à-dire qu'elle bute contre l'entrée étroite de cette rainure 31 et appuie donc le profilé 30 contre la pièce 3, mais, simultanément, l'épaulement 29 applique la pièce 3 contre les éléments 1 et 2 avec lesquels elle est en contact direct.Thus, the clamping of the part 3 is not done exclusively by the profile 30, as in the case of FIG. 6, but in addition, simultaneously, by the threaded rod 26 whose shoulder 29 is in direct contact with the part 3. The frustoconical head 27 is in abutment on the oblique flanks of the groove 31, that is to say that it abuts against the narrow entry of this groove 31 and therefore presses the profile 30 against the part 3, but , simultaneously, the shoulder 29 applies the part 3 against the elements 1 and 2 with which it is in direct contact.
Cette division de la force de serrage, permet de soulager l'effort exercé sur le profilé 30, si bien que celui-ci peut être réalisé en un matériau moins robuste que celui représenté sur la figure 6.This division of the clamping force makes it possible to relieve the force exerted on the profile 30, so that it can be made of a less robust material than that shown in FIG. 6.
La tête 27 a ici une forme tronconique dont la pente est coordonnée à la section trapézoïdale de la rainure 31, l'ouverture étroite de cette dernière étant formée par le petit côté laissé ouvert du trapèze. La figure 8 est une autre vue du même mode de réalisation que celui de la figure 7 et qui montre que les éléments 1 et 2 peuvent être non plus des élémentx de hauteur relativement grande, mais des longerons. Ici, le profilé 30 a la même hauteur que celle des longerons 1 et 2, mais il pourrait avoir une hauteur bien supérieure, notamment pour constituer un pied de meuble, auquel cas il doit évidemment être suffisamment rigide et robuste. Avec le montage des figures 7 et 8, les éléments 1 et 2 sont fixés l'un à l'autre par serrage direct des pièces 3 et 4 respectivement au moyen de l'épaulement 29 et de l'écrou 28, et après que le serrage ait été accompli, l'assemblage des éléments 1 et 2 est terminé. On peut ensuite, indépendamment de l'assemblage, mettre en place le profilé 30 sur la pièce 3 par glissement selon la flèche FI, la tête 27 de la tige filetée 26 étant engagée par l'extrémité ouverte de la rainure 31 sur la face supérieure du profilé 30. Le mode de réalisation des figures 9 et 10 montre une autre variante selon laquelle le maintien en place du profilé 30 est totalement indépendant du serrage de la pièce 3.The head 27 here has a frustoconical shape whose slope is coordinated with the trapezoidal section of the groove 31, the narrow opening of the latter being formed by the short side left open of the trapezoid. FIG. 8 is another view of the same embodiment as that of FIG. 7 and which shows that the elements 1 and 2 can no longer be elements of relatively large height, but longitudinal members. Here, the section 30 has the same height as that of the side members 1 and 2, but it could have a much greater height, in particular to constitute a furniture leg, in which case it must obviously be sufficiently rigid and robust. With the assembly of FIGS. 7 and 8, the elements 1 and 2 are fixed to each other by direct clamping of the parts 3 and 4 respectively by means of the shoulder 29 and the nut 28, and after the tightening has been accomplished, the assembly of elements 1 and 2 is complete. It is then possible, independently of the assembly, to place the profile 30 on the part 3 by sliding along the arrow FI, the head 27 of the threaded rod 26 being engaged by the open end of the groove 31 on the upper face profile 30. The embodiment of FIGS. 9 and 10 shows another variant according to which the holding in place of the profile 30 is completely independent of the tightening of the part 3.
En effet, la tige 26 a un épaulement 29 cylindro-tronconique dont l'extrémité prend appui sur les bords obliques d'une lumière oblongue 20 ménagée dans la pièce métallique 3 et le serrage se fait indépendamment du profilé 30 qui, sur la figure 9, n'est pas encore mis en place.Indeed, the rod 26 has a cylindrical-frustoconical shoulder 29 the end of which bears on the oblique edges of an oblong slot 20 formed in the metal part 3 and the tightening is done independently of the profile 30 which, in FIG. 9 , is not yet in place.
La partie cylindrique de l'épaulement 29 et la tête 27 restent donc dégagées avant comme après serrage.The cylindrical part of the shoulder 29 and the head 27 therefore remain free before as after tightening.
Sur la figure 10, on voit que l'on peut engager le profilé 30 par glissement, de la même manière que cela a été symbolisé par la flèche FI sur la figure 8.In FIG. 10, it can be seen that the profile 30 can be engaged by sliding, in the same way as has been symbolized by the arrow FI in FIG. 8.
Pour une mise en place correcte, il est bon ici que le matériau du profilé 30 soit un peu souple afin de s'adapter facilement et de se bloquer élastiquement quand il est en position correcte.For a correct installation, it is good here that the material of the profile 30 is a little flexible in order to adapt easily and to be blocked elastically when it is in correct position.
L'indépendance complète du profilé 30 par rapport à l'assemblage serré, permet de le remplacer facilement, soit lorsqu'il est endommagé, soit en le choisissant dans une collection au moment de l'achat de la structure.The complete independence of the section 30 with respect to the tight assembly, makes it easy to replace it, either when it is damaged, or by choosing it from a collection when purchasing the structure.
La figure 1 1 montre un mode de réalisation selon lequel le profilé 3 est indépendant de l'assemblage, comme décrit précédemment, mais est également indépendant de l'organe de serrage (vis, boulon, tige filetée). La pièce 3 possède une nervure de raidissage 35 qui arc-boute les faces extérieures des plans 10 et 1 1 et qui contribue ainsi à la robustesse et à la rigidité de la pièce 3 tout entière.Figure 1 1 shows an embodiment in which the profile 3 is independent of the assembly, as described above, but is also independent of the clamping member (screw, bolt, threaded rod). The part 3 has a stiffening rib 35 which archs the outer faces of the planes 10 and 1 1 and which thus contributes to the robustness and the rigidity of the whole part 3.
On profite de cette nervure 35 pour recourber ses extrémités libres afin de former deux lamelles convergentes 36, disposées à angle droit. Le profilé 30 présente deux rainures 37 disposées en conformité avec les lamelles 36, de telle sorte que lors de la mise en place du profilé 30, les lamelles 36 pénètrent dans les rainures 37.We take advantage of this rib 35 to curl its free ends in order to form two converging strips 36, arranged at right angles. The profile 30 has two grooves 37 arranged in accordance with the strips 36, so that when the profile 30 is put in place, the strips 36 penetrate the grooves 37.
Ici, le profilé 30 est en matériau plein, de sorte que les rainures 37 sont ménagées dans la masse même du profilé. Le profilé 30 doit être solidement tenu en place, ce qui peut être réalisé en donnant un petit décalage angulaire entre les lamelles 36 d'une part et les rainures 37 d'autre part, cela supposant que les lamelles 36 et/ou le matériau du profilé 30 présentent une certaine élasticité pour assurer d'une part une légère déformation lors de la mise en place du profilé 30 et un serrage élastique des lamelles 36 par le profilé 30. Sur la figure 12, on a représenté un mode de réalisation selon lequel la pièce 3 et le profilé 30 sont confondus. En effet, l'ensemble 3-30 comprend en une seule pièce d'une part les éléments fonctionnels nécessaires à l'assemblage par la pièce 3 : ailes 6-7, plans 10-1 1, appui de serrage pour la tige filetée 26 et d'autre part la finition du profilé 30. L'ensemble 3-30 est un profilé creux qui, outre les éléments fonctionnels rappelés ci- dessus, présente deux faces convergentes 38 prolongeant les ailes 6 et 7 et complétant, à la vue, l'angle d'assemblage sans laisser paraître aucun organe inesthétique.Here, the profile 30 is made of solid material, so that the grooves 37 are formed in the same mass of the profile. The profile 30 must be firmly held in place, which can be achieved by giving a small angular offset between the lamellae 36 on the one hand and the grooves 37 on the other hand, this assuming that the lamellae 36 and / or the material of the profile 30 have a a certain elasticity to ensure on the one hand a slight deformation during the positioning of the profile 30 and an elastic clamping of the strips 36 by the profile 30. In FIG. 12, an embodiment is shown according to which the part 3 and the profile 30 are combined. Indeed, the assembly 3-30 comprises in one piece on the one hand the functional elements necessary for assembly by the part 3: wings 6-7, planes 10-1 1, clamping support for the threaded rod 26 and on the other hand the finishing of the profile 30. The assembly 3-30 is a hollow profile which, in addition to the functional elements recalled above, has two converging faces 38 extending the wings 6 and 7 and completing, at sight, the angle of assembly without showing any unsightly body.
La tête 27 de la tige filetée 26 est tronconique à 90°, afin de s'adapter exactement aux parois également à 90° situées derrière les plans 10 et 11.The head 27 of the threaded rod 26 is tapered at 90 °, in order to adapt exactly to the walls also at 90 ° situated behind the planes 10 and 11.
Outre les picots 25 et les vis correspondant aux trous 43 (figure 6) on peut prévoir d'autres moyens de solidarisation des appuis 8 et 9 aux éléments 1 et 2, notamment de la colle.In addition to the pins 25 and the screws corresponding to the holes 43 (FIG. 6), other means can be provided for securing the supports 8 and 9 to the elements 1 and 2, in particular glue.
La figure 13 illustre la possibilité que donne l'invention d'adjoindre à la structure des organes accessoires ou complémentaires.FIG. 13 illustrates the possibility which the invention gives of adding accessory or complementary members to the structure.
A la partie supérieure de la figure 13, on voit un assemblage du même type que celui de la figure 12, c'est-à-dire que la structure comprend un ensemble 3-30 et à la partie inférieure, on voit une pièce 50 qui possède, comme une pièce 3, des ailes 51 et 52. des faces 53 et 54 et un passage 55 pour une tige filetée mais qui possède en plus une platine 56 située ici dans un plan perpendiculaire à celui des ailes 51-52 et des faces 53-54. Cette platine 56 réunit les faces 53 et 54 et contribue donc à renforcer la robustesse et la rigidité de l'ensemble mais sa fonction principale est de servir à la fixation d'un élément complémentaire.In the upper part of FIG. 13, we see an assembly of the same type as that of FIG. 12, that is to say that the structure comprises a set 3-30 and in the lower part, we see a part 50 which has, like a part 3, wings 51 and 52. faces 53 and 54 and a passage 55 for a threaded rod but which also has a plate 56 located here in a plane perpendicular to that of the wings 51-52 and sides 53-54. This plate 56 brings together the faces 53 and 54 and therefore contributes to reinforcing the robustness and the rigidity of the assembly, but its main function is to serve for fixing an additional element.
Ici, cet élément complémentaire est une roulette et son support 57, d'un type bien connu en soi et couramment disponible dans le commerce.Here, this complementary element is a caster and its support 57, of a type well known per se and commonly available commercially.
La fixation du support de roulette 57 à la platine 56 se fait de manière banale, au moyen de vis (non représentées) engagées dans des trous dudit support et des trous de la platine 56. La platine 56 est horizontale car le support 57 doit l'être aussi mais lorsque l'élément complémentaire appelle une autre orientation, la platine 56 a elle-même une autre position.The fixing of the caster support 57 to the plate 56 is done in a banal manner, by means of screws (not shown) engaged in holes in said support and holes in the plate 56. The plate 56 is horizontal because the support 57 must also be horizontal but when the complementary element calls for another orientation, the plate 56 itself has another position.
Parmi les éléments complémentaires possibles, on peut citer des paumelles et autres articulations, des glissières, un fond fixe ou amovible, etc. les moyens de fixation pouvant être d'un autre type que de simples vis (attaches rapides en particulier). La description ci-dessus se réfère exclusivement à un système vis-écrou pour réunir les pièces 3 et 4 mais il va de soi que tout autre moyen de fixation est possible, notamment une pièce de liaison engagée dans des rainures en queue d'aronde des pièces 3 et 4 et placées en regard, ou bien encore une tige élastiquement déformable solidaire de l'une des deux pièces 3 et 4 et engagée à force dans une rainure de l'autre pièce. On pourrait également prévoir une tige filetée 26 d'assez gros diamètre et creuse, réunissant les pièces 3 et 4 et dans laquelle une vis serait engagée pour la fixation spécifique d'un profilé 30.Among the possible complementary elements, there may be mentioned hinges and other articulations, slides, a fixed or removable bottom, etc. the fixing means being able to be of another type than simple screws (quick couplings in particular). The above description refers exclusively to a screw-nut system for joining parts 3 and 4, but it goes without saying that any other fixing means is possible, in particular a connecting part engaged in dovetail grooves of the parts 3 and 4 and placed opposite, or alternatively an elastically deformable rod secured to one of the two parts 3 and 4 and forcibly engaged in a groove in the other part. One could also provide a threaded rod 26 of fairly large diameter and hollow, joining parts 3 and 4 and in which a screw would be engaged for the specific fixing of a profile 30.
