Description
La présente invention concerne des moyens de fixation amovible d'un tube à un plateau. Elle concerne plus particulièrement quoique non exclusivement, la fixation d'un pied de table à son plateau. The present invention relates to means for removable attachment of a tube to a tray. It relates more particularly although not exclusively, the fixing of a table leg to its tray.
I1 est courant d'utiliser des tables équipées de pieds amovibles facilitant leur transport, leur stockage et leur rangement. It is common to use tables equipped with removable feet facilitating their transport, their storage and their arrangement.
Les moyens actuellement utilises comprennent généra- lement une platine destinée à etre fixee à la face infé- rieure du plateau et dont est solidaire un cellier apte à recevoir et retenir un pied tubulaire
Ces moyens de fixation présentent deux inconvénients, d'abord celui de ne pas procurer une tenue rigide du pied de telle sorte que la table est toujours branlante, et ensuite celui de laisser subsister, contre la face infé- rieure du plateau et apuras retrait des pieds, des colliers en saillies qui non seulement gênent l'empilage des plateaux mais risquent aussi de les rayer lors de leurs transports et de leurs rangements.The means currently used generally comprise a plate intended to be fixed to the lower face of the plate and to which is attached a cellar capable of receiving and retaining a tubular leg.
These fastening means have two drawbacks, firstly that of not providing a rigid hold for the foot so that the table is always loose, and then that of allowing it to remain, against the underside of the tray and after removal of the feet, protruding necklaces which not only hamper the stacking of the trays but also risk scratching them during transport and storage.
La présente invention vise à remédier à ces incon vénlents. A cet effet, les moyens qu'elle concerne comprennent, d'une part, une platine destinée à titre fixée contre la face intéressée du plateau par vis ou similaire et presentant, en son centre, une cuvette tronconique dont l'ouverture de grand diametre est destinée å être appliquée contre le plateau et dont le fond, de petit diamètre, est perce d'un trou central et porte un écrou logé dans la cuvette et, d'autre part, une coupelle tronconique d'angle au sommet inférieur à celui de la cuvette précitée, destinée à être fixée à l'extrémité de fixation amovible du tube, dont la grande base est d'un diamètre supérieur à celui du tube et dont la petite base, d'un diametre inférieur à celui du tube est engagée dans l'extrémité considérée de ce dernier, présente un trou central et porte unevis dont la tige filetée est orienté9 vers 1'extérieur du pied avec un débordement hors de la coupelle juste suffisant pour permettre son vissage dans ltécrou solidaire de la platine precitée. The present invention aims to remedy these problems. To this end, the means which it relates to comprise, on the one hand, a plate intended by title fixed against the interested face of the plate by screws or the like and having, in its center, a frustoconical bowl whose opening of large diameter is intended to be applied against the plate and whose bottom, of small diameter, is pierced with a central hole and carries a nut housed in the bowl and, on the other hand, a frustoconical cup with an angle at the top lower than that of the aforementioned bowl, intended to be fixed to the removable fixing end of the tube, the large base of which has a diameter greater than that of the tube and the small base of which has a diameter less than that of the tube is engaged in the considered end of the latter, has a central hole and carries a screw whose threaded rod is oriented towards the outside of the foot with an overflow from the cup just sufficient to allow it to be screwed into the nut secured to the aforementioned plate.
Le montage d'un tube se fait donc en vissant1 par sa rotation, la vis précitée dans l'écrou solidaire de la platine jusqu t à ce que la grande base de la coupelle tronconique du tube soit applique e fortement contre la face exterieure de la paroi tronconique de la cuvette de la platine. The assembly of a tube is therefore done by screwing1 by its rotation, the aforementioned screw in the nut secured to the plate until the large base of the frustoconical cup of the tube is applied strongly against the outer face of the frustoconical wall of the stage bowl.
Les formes tronconiques de la cuvette et de la coupelle assurent une tenue rigide de l'écrou et de la vis et leur application l'ume contre ltautre sous pression, procure une excellente rigidité a l'assemblage. The frustoconical shapes of the bowl and the cup ensure a rigid holding of the nut and the screw and their application to the urum against the other under pressure, provides excellent rigidity to the assembly.
La même coupelle peut évidemment être utilisée avec des pieds de diamètres différents, ce qui permet d'avoir le choix entre plusieurs tubes différents pour un même plateau. The same cup can obviously be used with feet of different diameters, which makes it possible to have the choice between several different tubes for the same tray.
Ceci est plus particulièrement avantageux lorsque le tube est un pied de table car on peut changer les pieds en fonction des touts des usagers et du mode d'utilisation de la table. This is more particularly advantageous when the tube is a table leg because it is possible to change the legs according to all the users and the mode of use of the table.
Enfin, si l'on souhaite que le tube ne soit pas perpeadiculaire au plateau, mais présente une légère inclinaison, ce qui dans le cas d'une table correspond à des pieds évases, il suffit de rivoir que l'axe de la coupelle tronconique ne soit pas normal au plan de fixation de la platine, mais fasse avec elle l'angle désiré. Finally, if it is desired that the tube is not perpeadicular to the plate, but has a slight inclination, which in the case of a table corresponds to flared legs, it suffices to rivet that the axis of the frustoconical cup is not normal to the plate's fixing plane, but makes the desired angle with it.
De toute façon, l'invention sera bien comprise à l'aide de la description qui suit en référence au dessin schématique annexé représentant, à titre d'exemple non limitatif, une forme dwexecution de ces moyens dans le cas de leur application à la fixation du pied d'une table à son plateau ::
Figure 1 est une vue en perspective montrant, lé- gèrement vu par dessous, un angle de table équipé d'un pied amovible fixé à l'aide des moyens selon l'invention
Figure 2 est une vue en plan de la platine destinée- à être fixée au plateau de la table
Figure 3 est une vue en coupe éclatée des moyens de fixation selon l'invention
Figure 4 est une vue en coupe suivant 4/4 de figure 1.Anyway, the invention will be well understood with the aid of the description which follows with reference to the appended schematic drawing representing, by way of nonlimiting example, a dwexecution form of these means in the case of their application to the fixing. from the foot of a table to its tray:
Figure 1 is a perspective view showing, slightly seen from below, a table angle equipped with a removable foot fixed using the means according to the invention
Figure 2 is a plan view of the plate intended to be fixed to the table top
Figure 3 is an exploded sectional view of the fastening means according to the invention
Figure 4 is a sectional view along 4/4 of Figure 1.
Dans l'exemple illustré sur le dessin, les moyes de 11 invention sont destinés a permettre la fixation amovible du pied tubulaire 2 d'une table à son plateau 3. In the example illustrated in the drawing, the hubs of the invention are intended to allow the removable fixing of the tubular leg 2 of a table to its plate 3.
Ces moyens comprennent, d'une part, une platine 4 illustrée sur la figure 2 et destinée à être fixée sur la face inférieure dn plateau 3 et, d'autre part, une coupelle 5 destinée à être firme à l'extrémité de fixation du pied tubulaire 2. These means comprise, on the one hand, a plate 4 illustrated in FIG. 2 and intended to be fixed on the underside of a plate 3 and, on the other hand, a cup 5 intended to be firm at the fixing end of the tubular leg 2.
Outre des trous 6 pour le passage de vis de fixation il et disposes à sa périphérie, la platine 4 présente, en son centre, une cuvette tronconique 8 liée à la platine 4 par sa grande base 9 et dont louver- ture délimitée par cette grande base 9, est donc destinée à être appliquée contre la face inférieure du plateau 3. La cuvette tronconique 8 porte sur son fond délimité par sa petite base 1i, un écrou 12 qui lui est fixé par soudage ou toute autre moyen approprié et dont la hauteur est inférieure à celle de la cuvette 8 qui lui sert de logement. Le fond délimité par la petite base Il de la cuvette 8 présente en outre un trou 12 co-axial à i l'écrou 12 et permettant l'engagement dans cet écrou d'une vis de même diamètre et même pas. In addition to holes 6 for the passage of fixing screws 11 and arranged at its periphery, the plate 4 has, in its center, a frustoconical bowl 8 linked to the plate 4 by its large base 9 and whose opening delimited by this large base 9, is therefore intended to be applied against the underside of the plate 3. The frustoconical bowl 8 carries on its bottom delimited by its small base 1i, a nut 12 which is fixed to it by welding or any other appropriate means and the height of which is less than that of the bowl 8 which serves as its housing. The bottom delimited by the small base Il of the bowl 8 also has a hole 12 co-axial to the nut 12 and allowing engagement in this nut of a screw of the same diameter and not even.
La coupelle 5 également tronconique est, pour les raisons exposées ci-après, d'un angle au sommet inférieur à celui de la cuvette 8. En outre, le diamètre de la grande base de la coupelle 5 est supérieur à celui du pied tubulaire 2, tandis que le diamètre de sa petite base est inférieur à celui du pied tubulaire 2, ce qui permet sa fixation par engagement de sa petite base dans l'extrémité considérée du pied tubulaire 2, comme illustré sur les figures 3 et 4. Comme le montre d'ailleurs ces figures, la coupelle 5 est fixée co-axia lement au pied tubulaire 2.. The cup 5 also frustoconical is, for the reasons explained below, an angle at the top less than that of the bowl 8. In addition, the diameter of the large base of the cup 5 is greater than that of the tubular base 2 , while the diameter of its small base is less than that of the tubular leg 2, which allows its fixing by engagement of its small base in the end considered of the tubular leg 2, as illustrated in Figures 3 and 4. As the moreover shows these figures, the cup 5 is fixed co-axially to the tubular base 2 ..
Enfin, comme le montre encore les figures 3 et 4 du dessin, la petite base de la coupelle 5 présente un trou 14 permettant le passage d'une vis 15 qui lui est fixée par sa tête 15a par soudage ou de toute autre manière appropriée,
On conçoit aisUment que suivant un procédé de fabrication simple de ces moyens, tant l'écrou 12 que la-vis 15 sont fixées à leurs supports respectifs, c'est-à-dire à la cuvette 8 de la platine 4 et à la coupelle 5 par soudure électrique, cette dernière étant elle même fixée au pied tubulaire 2 lui correspondant par le même procédé. Finally, as again shown in FIGS. 3 and 4 of the drawing, the small base of the cup 5 has a hole 14 allowing the passage of a screw 15 which is fixed to it by its head 15a by welding or in any other suitable manner,
It is easily understood that according to a simple method of manufacturing these means, both the nut 12 and the screw 15 are fixed to their respective supports, that is to say to the bowl 8 of the plate 4 and to the cup 5 by electrical welding, the latter itself being fixed to the tubular base 2 corresponding to it by the same process.
Il faut noter que la -longueur de la tige filetée de la vis 15 est choisie avec un leger débordement par rapport la grande base de la coupelle 5 de'maniôre à permettre son engagement et son vissage dans 1'écrou 12, ce qui peut se faire par simple rotation du pied tubulaire 2. il résulte des formes tronconiques de la cuvette 8 et de -la coupelle 5 une excellente tenue et, par consEquent, une excellente rigidité de l'écrou 12 par rapport à la platine 4 et de la vis li par rapport au pied tubulaire 2.En outre, comme le montre la figure 4, en fin de vissage de la vis 15 dans I'ecrou 12, la grande base de la coupelle 5 vient en appui sous pression contre la paroi tronconique-de la cuvette 8, ce qui contribue à procurer à l'assemblage une excellente rigidité. It should be noted that the length of the threaded rod of the screw 15 is chosen with a slight overhang relative to the large base of the cup 5 so as to allow it to be engaged and screwed into the nut 12, which can be make by simple rotation of the tubular leg 2. it results from the frustoconical shapes of the bowl 8 and of the cup 5 an excellent hold and, consequently, an excellent rigidity of the nut 12 relative to the plate 4 and of the screw li with respect to the tubular base 2. Furthermore, as shown in FIG. 4, at the end of the screwing of the screw 15 in the nut 12, the large base of the cup 5 presses against the frustoconical wall under pressure. the bowl 8, which contributes to providing the assembly with excellent rigidity.
Les moyens selon l'invention sont donc d'une constitution extrêmement simple, d'une fabrication rapide et peu onéreuse, et permettent en outre un assemblage simple et rapide d'un pied tubulaire 2 à un plateau de table 3. The means according to the invention are therefore of an extremely simple constitution, of rapid and inexpensive manufacture, and also allow simple and rapid assembly of a tubular leg 2 to a table top 3.
Dans la forme d'exécution la plus simple de ces moyens, la fixation du pied tubulaire 3 est réalisée perpendiculairement au plan du plateau 3 de la table. In the simplest embodiment of these means, the fixing of the tubular leg 3 is carried out perpendicular to the plane of the plate 3 of the table.
Cependant, si on désire que cette fixation se fasse avec un léger angle procurant une meilleure stabilité à la table qui sera ainsi pourvue de pieds évasés, la cuvette 8 est réalisée dans la platine i de manière que l'axe de révolution de sa paroi tronconique ne soit pas perpendiculaire an plan de fixation de la platine 4. However, if it is desired that this fixing be done at a slight angle providing better stability to the table which will thus be provided with flared feet, the bowl 8 is produced in the plate i so that the axis of revolution of its frustoconical wall is not perpendicular to the plate 4 fixing plane.
Cette inclinaison de cet axe peut être réalisée, par exemple comme illustré sur le dessin, par réalisation d'un pli 16 en arc de cercle entourant partiellement la grande base 2 de la cuvette 8, ce pli t6 étant réalisé tout simplement par emboutissage simultanément a la formation de la cuvette 8.This inclination of this axis can be achieved, for example as illustrated in the drawing, by making a fold 16 in an arc of a circle partially surrounding the large base 2 of the bowl 8, this fold t6 being produced simply by stamping simultaneously with the formation of the bowl 8.
On peut noter en outre que l'agencement des moyens selon l'invention permet d'adapter à un m8me plateau 3 des pieds tubulaires 2 de diamètres et/ou de longueurs différentes. Il suffit en effet d'utiliser des pieds dont la coupelle 5 est un angle au sommet inferieur ou egal a celui de la cuvette 8 et une grande base d'un diamètre inférieur ôu égal à celui de la grande base 9 de la cuvette 8. It may further be noted that the arrangement of the means according to the invention makes it possible to adapt tubular legs 2 of different diameters and / or lengths to the same plate 3. It suffices in fact to use feet whose cup 5 is an angle at the top less than or equal to that of the bowl 8 and a large base with a diameter less than or equal to that of the large base 9 of the bowl 8.
On peut enfin concevoir une série de pieds diffé- rents tant par leurs diamètres que par leurs longueurs, leurs extrémités de fixation seraient équipées dès l'origine d'une même coupelle 5. Finally, it is possible to design a series of feet which are different in both their diameters and their lengths, their fixing ends being fitted from the outset with the same cup 5.
Par ailleurs, on peut noter que, contrairement aux moyens actuellement connus, après démontage des pieds tubulaires, les platines 5 ne présentent aucune saillie notable par rapport à la face inférieure du plateau de la table. Furthermore, it can be noted that, unlike currently known means, after dismantling the tubular legs, the plates 5 have no significant projection relative to the underside of the table top.
Comme il va de soi et comme il ressort de ce qui précède, l'invention ne se limite pas à la seule forme d'exécution de ces moyens qui a e été décrite ci-dessus à titre d'exemple non limitatif ; elle en embrasse, au contraire, toutes les variantes de réalisation. C'est ainsi que, par exemple, ces moyens de fixation d'un tube à un plateau peuvent être utilises à des fins autres que l'assemblage de pieds tubulaires à des plateaux de tables. As is obvious and as follows from the above, the invention is not limited to the only embodiment of these means which has been described above by way of non-limiting example; on the contrary, it embraces all of its variant embodiments. Thus, for example, these means for fixing a tube to a tray can be used for purposes other than assembling tubular legs to table tops.
