Abstract

The concealed furniture joint secures the end of a hollow rectangular section rail (1) to a round hollow post (2). A length (3) of 'T' section is rivetted (6) to the post so that the stem (3b) projects horizontally to form a tongue, and a relatively elastic rectangular section cellular block (4) houses onto the tongue. A headless screw (9) secures the block on the tongue. The block is a sliding fit in the extremity of the rail. The screw (9) is accessible through a rail wall hole, being driven further to press the block lobe against the opposite rail wall and secure the joint. The block (4) may have a central longitudinal diaphragm wall (4d) with a cross wall (4c) countering the screw thrust.

Description

Dispositif pour fixer deux éléments tubulaires
transversalement l'un par rapport à l'autre.
Device for fixing two tubular elements
transversely with respect to each other.

On connaît de nombreux moyens pour fixer deux éléments tubulaires transversalement l'un par rapport à l'autre; on peut, par exemple, souder ces deux éléments l'un à l'autre. Mais ces moyens de fixation sont, en général, visibles, ce qui peut être gênant, par exemple lorsque les éléments font partie d'un meuble tel qu'un siège. Numerous means are known for fixing two tubular elements transversely to one another; one can, for example, weld these two elements to each other. But these fixing means are, in general, visible, which can be annoying, for example when the elements are part of a piece of furniture such as a seat.

La présente invention a pour objet un dispositif pour fixer deux éléments tubulaires transversalement l'un par rapport à l'autre qui est au contraire pratiquement invisible
Le dispositif selon l'invention est caractérisé en ce qu'il comprend un élément rigide propre à être fixé sur un premier tube et comportant, quand il est en place, une partie s étendant transversalement par rapport à ce tube, et une pince, en une matière présentant une certaine élasticité, qui est propre à embrasser ladite partie de l'élément et dont la dimension dans la direction perpendiculaire au plan de ladite partie est sensiblement e- gale à la dimension correspondante du second tube, et en ce que l'une des branches i la pince comporte un trou qui, lorsque la pince est enfilée sur la partie transversale de l'élément, se trou ve en regard d'un trou taraudé prévu dans cette partie transversale.
The subject of the present invention is a device for fixing two tubular elements transversely to each other which, on the contrary, is practically invisible
The device according to the invention is characterized in that it comprises a rigid element suitable for being fixed on a first tube and comprising, when it is in place, a part extending transversely relative to this tube, and a clamp, in a material having a certain elasticity, which is capable of embracing said part of the element and whose dimension in the direction perpendicular to the plane of said part is substantially equal to the corresponding dimension of the second tube, and in that the one of the branches i the clamp has a hole which, when the clamp is threaded on the transverse part of the element, is hole ve opposite a tapped hole provided in this transverse part.

Pour fixer les deux tubes l'un à l'autre, il suffit dgas- sujettir l'élément rigide sur le premier tube, par exemple par des rivets, d'enfiler la pince sur la partie transversale de cet élé- ment, puis le second tube sur la pince, d'enfiler une vis dans le trou de la pince, un trou correspondant ayant été préalablement formé dans le second tube, et de visser cette vis dans le trou taraudé de la partie transversale de l'élément rigide. L'extrémité de cette vis vient alors presser contre la paroi du second tube, la partie de la pince qui lui fait face et qui est ainsi serrée entre la vis et ce second tube, ce qui immobilise ce dernier. To fix the two tubes to each other, it suffices to subject the rigid element to the first tube, for example by rivets, to thread the clamp on the transverse part of this element, then the second tube on the clamp, thread a screw into the hole of the clamp, a corresponding hole having been previously formed in the second tube, and screw this screw into the tapped hole of the transverse part of the rigid element. The end of this screw then presses against the wall of the second tube, the part of the clamp which faces it and which is thus clamped between the screw and this second tube, which immobilizes the latter.

L'invention est particulièrement applicable à la fixation d'éléments de mobilier (sièges, meubles de rangement, accotoirs de lits, etc.). En effet, dans ces différents cas, la pré- sence du dispositif de fixation ne se manifeste alors que par la présence des trous sur la face inférieure des tubes horizontaux. The invention is particularly applicable to the fixing of pieces of furniture (seats, storage units, bed armrests, etc.). In fact, in these different cases, the presence of the fixing device is only manifested by the presence of the holes on the underside of the horizontal tubes.

On a décrit ci-après, à titre a'exemple non limitatif, un mode de réalisation du dispositif de fixation selon l'invention avec réference au dessin annexé dans lequel
La Figure 1 est une vue en perspective éclatée montrant les deux tubes à réunir et le dispositif de fixation;
La Figure 2 est une vue en coupe de l'ensemble des deux tubes fixés l'un à l'autre,
La Figure 3 en est une vue en plan.
An embodiment of the fixing device according to the invention has been described below, by way of non-limiting example, with reference to the appended drawing in which
Figure 1 is an exploded perspective view showing the two tubes to be joined and the fixing device;
FIG. 2 is a sectional view of the assembly of the two tubes fixed to each other,
Figure 3 is a plan view.

Au dessin, on voit un tube 1 qui doit être fixé transversalement sur un tube 2; le tube 1 est ici rectangulaire. In the drawing, we see a tube 1 which must be fixed transversely on a tube 2; the tube 1 is here rectangular.

La fixation du tube 1 sur le tube 2 est assurée à l'aide d'un té 3 et d'une pince 4. The tube 1 is fixed to the tube 2 using a tee 3 and a clamp 4.

La branche longitudinale 3a du té 3 a une longueur inférieure à la hauteur du tube 1 et comporte des trous 5 pour le passage de rivets 6; sa branche transversale 3b est percée d'un trou taraudé 7. The longitudinal branch 3a of the tee 3 has a length less than the height of the tube 1 and has holes 5 for the passage of rivets 6; its transverse branch 3b is pierced with a tapped hole 7.

La pince de fixation 4 est réalisée en matière présentant une certaine élasticité, par exemple en "Nylon". L'écartement entre ses branches 4a et 4b est sensiblement égal à l'épaisseur de la branche transversale 3b du té 3 et sa section extérieure est sensiblement égale à la section intérieure du tube 1. Sa branche 4b est percée d'un trou 8 permettant le passage d'une vis 9 au pas du trou taraudé 7. Ce trou 8 se trouve en regard d'une partie pleine 4c non flexible de la pince. La référence 4d désigne un voile médian qui est muni en son milieu d'une fente longitudinale 4e au niveau des branches 4a et 4b. The fixing clip 4 is made of a material having a certain elasticity, for example "Nylon". The spacing between its branches 4a and 4b is substantially equal to the thickness of the transverse branch 3b of the tee 3 and its outer section is substantially equal to the inner section of the tube 1. Its branch 4b is pierced with a hole 8 allowing the passage of a screw 9 at the pitch of the threaded hole 7. This hole 8 is located opposite a non-flexible solid part 4c of the clamp. The reference 4d designates a median web which is provided in its middle with a longitudinal slot 4e at the level of the branches 4a and 4b.

Pour fixer le tube 1 sur le tube 2, on forme dans ce tube 2 deux trous 11 ayant l'écartement des trous 5 et on fixe sur ce tube le té 3 à l'aide des deux rivets 6 montés en aveugle. To fix the tube 1 on the tube 2, two holes 11 are formed in this tube 2 having the spacing of the holes 5 and the tee 3 is fixed to this tube using the two rivets 6 mounted blind.

Puis on monte la pince 4 sur la branche transversale 3b du té 3 et on met en place la vis 9 qui vient se visser dans le trou taraudé 7. On emboite alors le tube transversal 1 sur la pince 4 de façon qu'il vienne en butée sur le tube 2. Un trou 10 a été préalablement formé dans ce tube de façon à se trouver en regard de la vis 9. I1 ne reste plus qu'à serrer la vis 9 à l'aide d'une clef introduite dans le trou 10, de façon que l'extrémité de cette vis repousse la partie supérieure 4c de la pince et vienne la serrer contre la paroi du tube 1. Les rivets 6 sont cachés par la pince 4 qui est elle-même cachée par le tube 1. Le trou 10 est pratiquement invisible.  Then the clamp 4 is mounted on the transverse branch 3b of the tee 3 and the screw 9 which is screwed into the tapped hole 7 is put in place. The transverse tube 1 is then fitted onto the clamp 4 so that it comes in abutment on the tube 2. A hole 10 has been previously formed in this tube so as to be opposite the screw 9. I1 only remains to tighten the screw 9 using a key inserted in the hole 10, so that the end of this screw pushes the upper part 4c of the clamp and comes to tighten it against the wall of the tube 1. The rivets 6 are hidden by the clamp 4 which is itself hidden by the tube 1 The hole 10 is practically invisible.

I1 va de soi que la présente invention ne doit pas être considérée comme limitée au mode de réalisation décrit et représenté, mais en couvre, au contraire, toutes les variantes It goes without saying that the present invention should not be considered as limited to the embodiment described and shown, but on the contrary covers all variants thereof.
