Abstract

The self-locking connector secures square or rectangular hollow section members at the joints of furniture pieces etc. It comprises two dissimilar parts (A & B). The main part (A) is a plate (1) with two edges (a,a') which bear on the walls of a member being secured, using two cranked flaps (2',2) to form a 'U' section tail. The second part is a rectangular spacer (B) which fits between the flaps (2) and the member being secured, and permits location of the connector in preparation for the fixing of transverse members. The plane contg. the arrisses is angled to the plate, the fitting forming a grip on one of the transverses once pivoted until the edges bite into the walls. The arrisses may be incorporated in a rectangular window in an angled extension of the plate.

Description

La présente invention concerne un dispositif permettant la réalisation de structures métalliques à l'aide de tubes ou de barres de section carrée ou rectangulaire, notamment rayonnage, présentoir etc... The present invention relates to a device for the realization of metal structures using tubes or bars of square or rectangular section, including racking, display etc ...

Le brevet principal (NO 80 01823) a pour objet un dispositif autobloquant composé de deux pièces en forme d'étrier fermé, réunies ent'elles par une seule vis assurant le blocage de l'ensemble en un point choisi d'un profilé. The main patent (No. 80 01823) relates to a self-locking device consisting of two parts in the form of closed stirrup, joined together by a single screw ensuring the locking of the assembly at a selected point of a profile.

La présente invention concerne un perfectionnement à un tel dispositif, et une réalisation plus économique. The present invention relates to an improvement to such a device, and a more economical embodiment.

Selon l'invention, le dispositif comporte également deux pièces principales mais non semblables plus un boulon. L'une des pièces constitue un etrier fermé A). Elle est constituée par une plaque de tôle présentant en sa partie centrale une plateforme plane, à une extrémité une partie galbee traversée par un trou rectangulaire permettant le libre passage d'un profilé, à l'autre extrémite par un pliage en U.Les ailes de 1'U sont perpendiculaires à la plateforme centrale. La base de-l'U est traversee d'un trou destiné au passage d'une vis. According to the invention, the device also comprises two main parts but not similar plus a bolt. One of the pieces is a closed beam A). It is constituted by a sheet metal plate having in its central part a flat platform, at one end a curved portion traversed by a rectangular hole allowing the free passage of a profile, at the other end by a U-fold. U are perpendicular to the central platform. The base of the U is crossed by a hole intended for the passage of a screw.

La pièce présente donc un plan de symétrie comprenant l'axe médian de 1'U. Le trou pratique dans la partie galbée est dimensionné de telle sorte que la largeur du trou prise perpendiculairement au plan de symétrie est légèrement superieure à l'une des dimensions du profilé, alors que dans l'autre sens, la projection de la distance séparant les arêtes (a) et (al) du trou sur le plan de la plateforme est légèrement inférieure à l'autre dimension du profilé. La droite reliant les arêtes fait avec le plan de la plateforme un angle favorisant le coincement. The piece therefore has a plane of symmetry comprising the median axis of 1'U. The practical hole in the curved portion is dimensioned such that the width of the hole taken perpendicular to the plane of symmetry is slightly greater than one of the dimensions of the profile, while in the other direction, the projection of the distance separating edges (a) and (al) of the hole on the plane of the platform is slightly smaller than the other dimension of the profile. The line joining the edges makes the plane of the platform an angle favoring jamming.

La partie de la pièce comportant 1'U et la plateforme sont rendues rigides grâce à une bonne nervuration de la tôle. Par contre, l'extrémité galbée n'est pas nervurée, ce qui lui confère une certaine souplesse. The part of the part comprising 1'U and the platform are made rigid by good ribbing of the sheet. On the other hand, the curved end is not ribbed, which gives it a certain flexibility.

L'autre pièce, ou pièce (B) est une simple cale de tôle, d'epaisseur similaire à celle constituant la pièce (A), de largeur égale à la largeur de la plateforme de la pièce (A) et de longueur egale à la longueur de la plateforme de la pièce (A). La cale pourra comporter une encoche facilitant sa mise en place lors du montage. The other part or part (B) is a simple sheet metal shim, of similar thickness to that constituting the part (A), of width equal to the width of the platform of the part (A) and of length equal to the length of the platform of the room (A). The wedge may include a notch facilitating its implementation during assembly.

La mise en place du dispositif ainsi constitué s'effectue de la façon suivante. La pièce (A) est enfilée sur le premier profile jusqu'à l'endroit choisi. Elle se présente alors de telle sorte que la plateforme fait avec l'axe principal du profilé un angle fermé. A L'aide d'une clé à molette insérée entre les joues de 1'U, on force modérement pour amener la plateforme en position orthogonale par rapport à l'axe du profilé. On insère alors la cale entre la paroi du profile et les plans des ailes de l'U. On relache ensuite l'effort. L'ensemble tient alors de lui-même en position et la plateforme reste perpendiculaire à l'axe du profilé. The establishment of the device thus constituted is carried out as follows. The piece (A) is threaded on the first profile to the chosen place. It is then in such a way that the platform forms a closed angle with the main axis of the profile. With the help of a wrench inserted between the cheeks of the U, one moderately forces to bring the platform orthogonal to the axis of the profile. The wedge is then inserted between the wall of the profile and the planes of the wings of the U. Then release the effort. The assembly then holds itself in position and the platform remains perpendicular to the axis of the profile.

Dans le cas le plus fréquent d'assemblage de 3 tubes carrés, la largeur de la plateforme et par conséquent de la cale, sera égale au côté de la section carrée du tube, et la hauteur du sommet des ailes du 'U' au plan de la plateforme sera égale au côté de la section carrée du tube, additionnée de l'épaisseur de la cale (B). La largeur de l'U sera égale ou inférieure au côté de la section carrée du tube. In the most frequent case of assembly of 3 square tubes, the width of the platform and consequently of the wedge, will be equal to the side of the square section of the tube, and the height of the top of the wings of the 'U' to the plane of the platform will be equal to the side of the square section of the tube, plus the thickness of the shim (B). The width of the U will be equal to or less than the side of the square section of the tube.

Selon les utilisations, ces dimensions pourront être modifiées. Depending on the uses, these dimensions may be modified.

Une fois le dispositif en position sur le premier tube, il est possible de placer un second tube en appui sur la cale posée sur la plateforme. Celui-ci se trouvera automatiquement en position orthogonale par rapport au premier. Ensuite, un troisième tube tou traverse), judicieusement perce estplace en appuiS d'une part sur le second tube, et d'autre part sur le sommet des ailes de l'U de la pièce (A). Il est maintenu en position par une vis (8) et un écrou (10). Le trou est généralement percé dans le tube de sorte que l'extrémité de ce tube, coupée d'équerre, vienne en butée sur le premier tube, ce qui assure l'orthogonalité des trois tubes entr'eux. Once the device is in position on the first tube, it is possible to place a second tube resting on the hold placed on the platform. This one will be automatically in orthogonal position compared to the first one. Then, a third tube crosses), judiciously pierced is placed in support on the one hand on the second tube, and secondly on the top of the wings of the U of the piece (A). It is held in position by a screw (8) and a nut (10). The hole is generally pierced in the tube so that the end of this tube, cut square, comes into abutment on the first tube, which ensures the orthogonality of the three tubes between them.

L'invention sera illustree sans être aucunement limitée par la description qui suit, faite en référence aux dessins annexés sur lesquels
La fig. 1 représente en perspective les éléments constitutifs du dispositif, nervurations non représentées,
La fig. 2 la première phase de la mise en place du dispositif sur un montant en tube carré, vue en coupe.The invention will be illustrated without being in any way limited by the description which follows, made with reference to the appended drawings in which
Fig. 1 represents in perspective the constituent elements of the device, ribs not shown,

La fig. 3 la mise en place du dispositif avec la cale, vue en coupe,
La fig. 5 le montage d'un panneau vertical fixé à l'aide de deux des dispositifs.Fig. 3 the installation of the device with the hold, seen in section,
Fig. 5 mounting a vertical panel attached using two of the devices.

Dans l'exemple donné en figure 1, on remarquera la plateforme 11) prolongée à gauche d'une partie pliée en forme de U et à droite par une partie galbée en forme semi-cylindrique, traversée par un trou destine au libre passage d'un profilé. Les arêtes (a) et (al) sont parallèles entre elles, et perpendiculaires au plan de symétrie de la pièce (A). La distance qui les sépare, projetée sur le plan de la plateforme (1) est legerement inférieure au côté du profil à serrer. Par contre, la distance entre les bords parallèles (b) et (b') est légèrement superieure au côte du profil. In the example given in FIG. 1, the platform 11) extended to the left of a U-shaped folded part and to the right by a semi-cylindrical shaped portion traversed by a hole intended for the free passage of a profile. The edges (a) and (a1) are parallel to each other and perpendicular to the plane of symmetry of the piece (A). The distance that separates them, projected on the plane of the platform (1) is slightly lower than the side of the profile to be clamped. On the other hand, the distance between the parallel edges (b) and (b ') is slightly greater than the side of the profile.

L'angle o < que fait le plan reliant les arêtes (a) et (a') avec le plan de la plateforme (1) est de l'ordre de 15 à 200, et favorise le coincement. The angle θ which makes the plane connecting the edges (a) and (a ') with the plane of the platform (1) is of the order of 15 to 200, and promotes jamming.

Si une charge est appliquée sur la plateforme (1), la pièce (A) étant enfilée sur un montant vertical, celle-ci se coince et ne peut plus descendre. If a load is applied to the platform (1), the part (A) is threaded on a vertical upright, it becomes jammed and can not go down.

Cette pièce est construite en tôle d'acier. Des nervures, non représentées en fig. 1, rigidifient l'ensemble de la base de l'U et de la plateforme. This piece is made of sheet steel. Ribs, not shown in fig. 1, stiffen the entire base of the U and the platform.

Un trou (7) dans la base de l'U permet l'introduction de la vis t8) en fin de montage. A hole (7) in the base of the U allows the introduction of the screw t8) at the end of assembly.

La cale (B), également en tôle, permet l'immobilisation de la pièce (A) lors du montage. L'échancrure assure le positionnement exact de la cale par rapport au montant vertical; elle n'est pas indispensable. The shim (B), also in sheet metal, allows the immobilization of the part (A) during assembly. The indentation ensures the exact positioning of the wedge relative to the vertical upright; it is not essential.

Les Fig 2, 3 montrent le processus de mise en place du dispositif sur un montant vertical en tube carré. Un effort de torsion dirigé vers le bas est obtenu au moyen d'une clé à molette, jusqu'à mise en place de la cale (B). Cet effort est transmis et maintenu au niveau de l'arête (al) qui marque une légère empreinte dans le tube et assure le coincement de l'ensemble. Tout effort vertical appliqué de haut en bas au niveau de la plateforme aura pour effet d'augmenter cette force de coincement. Figures 2, 3 show the process of setting up the device on a vertical upright square tube. A downward twisting force is obtained by means of a wrench until the wedge (B) is fitted. This force is transmitted and maintained at the edge (al) which marks a slight impression in the tube and ensures the jamming of the assembly. Any vertical force applied from top to bottom at the platform will increase this jamming force.

La fig. 4 représente le montage final d'un noeud d'assemblage. On distingue le longeron vu en bout et la traverse tubulaire traversée par la vis (8) et maintenue en place par l'écrou (10). Fig. 4 represents the final assembly of an assembly node. We distinguish the spar seen end and tubular cross traversed by the screw (8) and held in place by the nut (10).

La fig. 5 représente le montage d'un panneau le long d'un tube carré, tel que l'on en utilise dans les expositions par exemple. On remarque l'utilisation d'une cale (9) de même épaisseur que la cale (B) destinée à assurer le serrage de la pièce A parallèlement au bord du panneau. Fig. 5 shows the mounting of a panel along a square tube, as used in exhibitions for example. Note the use of a shim (9) of the same thickness as the shim (B) for clamping the piece A parallel to the edge of the panel.

Le dispositif objet de l'invention est généralement construit en tôle d'acier emboutie, mais il peut, selon les besoins, être réalisé en tout autre matériau, notamment en matière plastique injectee.  The device of the invention is generally constructed of pressed steel sheet, but it can, according to need, be made of any other material, in particular plastic injected.
