Abstract

The coupling (1) connects two different diameter tubes at right angles. It is made of plastics and pushed into the open end of the larger tube after the smaller tube has been passed through a hole in the wall of the larger tube. The pin (7) is forced through a hole in the wall of the smaller tube until the curved surface (5) rests on the outside of the smaller tube. The two faces (6a,b) straddle the smaller tube and the arms (3) are a force fit inside the larger tube.

Description

Dispositif de liaison de deux tubes.Device for connecting two tubes.

Dans le domaine particulier du meuble et de la literie, il est intéressant de pouvoir disposer d'un sommier démontable ce, pour en diminuer le volume de stockage et de transport. Généralement, les sommiers les moins encombrants sont les sommiers métalliques constitués par un cadre soutenant un matériau de garniture élastique du type treillis métallique ou lattes de bois. On sait atteler de manière démontable ce matériau de garniture au cadre, notamment lorsqu'il s'agit de lattes de bois. L'invention entend fournir une solution à la démontabilité du cadre du sommier. In the particular field of furniture and bedding, it is advantageous to be able to have a removable box spring, to reduce the volume of storage and transport. Generally, the least bulky box springs are the metal bed bases formed by a frame supporting an elastic lining material of the metal mesh or wooden slat type. It is known to attach this lining material to the frame in a removable manner, in particular in the case of wooden slats. The invention intends to provide a solution to the dismantling of the box spring frame.

Ainsi, plus précisément, l'invention a pour objet un dispositif de liaison de deux tubes perpendiculaires coplanaires de diamètres différents au moins au niveau de leur liaison, le tube de plus petit diamètre pénètrant par l'une de ses extrémités dans un orifice latéral dont est pourvue l'extrémité de l'autre tube. Ce dispositif est constitué par un embout susceptible d'être enfoncé à force b l'extrémité du tube de grand diamètre et possédant dans une direction axiale, un élément de retenue du tube de petit diamètre coopérant avec un orifice radial ménagé à l'extrémité du petit tube interne au tube de grand diamètre. Thus, more specifically, the subject of the invention is a device for connecting two perpendicular coplanar tubes of different diameters at least at their connection, the tube of smaller diameter penetrating by one of its ends into a lateral orifice, is provided with the end of the other tube. This device consists of an end-piece capable of being forced into the end of the tube of large diameter and having in an axial direction, a retaining element of the tube of small diameter cooperating with a radial orifice formed at the end of the tube. small tube inside the large diameter tube.

Il sera intéressant de prévoir que la face extérieure de l'embout soit sensiblement sphérique. It will be interesting to provide that the outside face of the end piece is substantially spherical.

L'invention sera mieux comprise au cours de la description donnée ci-après à titre indicatif et non limitatif qui permettra d'en dégager les avantages et les caractéristiques secondaires. The invention will be better understood during the description given below by way of indication and without limitation, which will make it possible to identify the advantages and the secondary characteristics thereof.

Il sera fait référence aux dessins annexés dans lesquels
- La figure 1 est une vue en perspective de l'embout selon l'invention,
- Les figures 2 et 3 illustrent par des coupes orthogonales la liaison de deux tubes au moyen du dispositif de la figure 1.Reference will be made to the accompanying drawings in which
FIG. 1 is a perspective view of the nozzle according to the invention,
- Figures 2 and 3 illustrate by orthogonal sections the connection of two tubes by means of the device of Figure 1.

En se reportant à ces figures, on voit un embout en matériau plastique 1, comportant une tête 2 et une partie d'emmanchement 3, pourvue de manière connue d'ergots 4 souples créant l'effort de friction nécessaire au maintien de l'embout emmanché dans une structure tubulaire. Cette partie d'emmanchement 3 est évidée, l'évidement étant limité par une surface concave 5 (ici cylindrique) et deux faces parallèles 6a et 6b, de manière à donner à cette partie d'emmanchement la forme d'un cavalier. Axialement, au centre de cet évidement, l'embout 1 est pourvu d'une partie 7 en forme de pion formant élément de retenue et de verrouillage des tubes à assembler comme expliqué ci-après en regard des figures 2 et 3. Referring to these figures, there is shown a nozzle made of plastic material 1, comprising a head 2 and a fitting part 3, provided in known manner with flexible lugs 4 creating the friction force necessary to maintain the nozzle. fitted into a tubular structure. This fitting part 3 is hollowed out, the recess being limited by a concave surface 5 (here cylindrical) and two parallel faces 6a and 6b, so as to give this fitting part the shape of a jumper. Axially, at the center of this recess, the end piece 1 is provided with a pin-shaped part 7 forming a retaining and locking element for the tubes to be assembled as explained below with reference to FIGS. 2 and 3.

Sur ces figures, on voit un tube 10, de grand diamètre, pourvu au voisinage de son extrémité d'une ouverture latérale 10a, qui peut être traversée par un tube 11 de plus petit diamètre. In these figures, we see a tube 10, of large diameter, provided in the vicinity of its end with a lateral opening 10a, which can be crossed by a tube 11 of smaller diameter.

L'extrémité lla du tube 11 se trouve ainsi logée à l'intérieur du tube 10 et perpendiculaire à l'axe de ce dernier. L'extrémité lla est également pourvue d'un orifice transversal 12 qui se trouve placé coaxialement au tube 10 quand le tube 11 est correctement disposé. A ce moment, on enfile l'embout 1 à force dans l'ouverture extrême lOb du tube 10. L'élément 7 est alors introduit dans l'orifice 12 tandis que la partie 3 vient s'emmancher dans le tube 10 et vient chevaucher l'extrémité lla du tube 11. La surface 5 épouse donc la surface extérieure de la partie lla du tube 11.The end 11a of the tube 11 is thus housed inside the tube 10 and perpendicular to the axis of the latter. The end 11a is also provided with a transverse orifice 12 which is placed coaxially with the tube 10 when the tube 11 is correctly arranged. At this time, the end piece 1 is forced into the extreme opening 10b of the tube 10. The element 7 is then introduced into the orifice 12 while the part 3 is fitted into the tube 10 and overlaps the end 11a of the tube 11. The surface 5 therefore follows the external surface of the part 11a of the tube 11.

L'exemple ci-dessus décrit fait référence à des tubes cylindriques. L'invention s'applique également à toute autre forme de section du tube. En outre, le tubell peut être de même diamètre que le tube 10 et ne possèder qu'une extrémité lla de diamètre réduit. On notera également que la tête (2) de l'embout possède une surface sensiblement sphérique qui constitue un élément par lequel le sommier ou les tubes peuvent reposer sans dommage au sol lors de leur stockage vertical. The example described above refers to cylindrical tubes. The invention also applies to any other form of section of the tube. In addition, the tubell can be of the same diameter as the tube 10 and have only one end 11a of reduced diameter. It will also be noted that the head (2) of the endpiece has a substantially spherical surface which constitutes an element by which the bed base or the tubes can rest without damage to the ground during their vertical storage.

On voit donc qu'un cadre de sommier métallique peut être, grâce à l'invention, stocké et livré démonté. Quatre embouts 1 suffisent à le monter, à verrouiller la liaison et à assurer le maintien en bonne position des longerons 10 du cadre par rapport aux traverses 11. It can therefore be seen that, thanks to the invention, a box spring frame can be stored and delivered disassembled. Four end pieces 1 are sufficient to mount it, to lock the connection and to ensure that the longitudinal members 10 of the frame are kept in good position relative to the crosspieces 11.

L'inveotion n'est pas limitée à la description qui vient d'en être donnée mais couvre au contraire toutes les variantes  The invention is not limited to the description which has just been given, but on the contrary covers all variants
