Description

PED DEMONTABLE, NOTAMMENT POUR MEUBLES DE BUREAUX L présente invention a pour objet un pied démontable, destiné en particulier, mais non exclusivement, aux meubles de bureaux tels que des sièges ou des classeurs rotatifs. REMOVABLE FOOT, ESPECIALLY FOR OFFICE FURNITURE The present invention relates to a removable foot, intended in particular, but not exclusively, for office furniture such as seats or rotary filing cabinets.

On sait que les sièges pivotants de bureaux sont constitués, outre l'assise proprement dite, d'un tube vertical intégré à sa partie inférieure dans un pied, destiné à reposer sur le sol, comprenant généralement de trois à six branches. Ainsi, le siège peut tourner autour du tube, et dans certains cas, les branches du pied sont munies de roulettes simples ou doubles, permettant de déplacer le siège ou le meuble.We know that the swivel office chairs consist, in addition to the seat itself, of a vertical tube integrated at its lower part in a foot, intended to rest on the ground, generally comprising three to six branches. Thus, the seat can rotate around the tube, and in some cases, the legs of the foot are provided with single or double rollers, making it possible to move the seat or the piece of furniture.

Actuellement, les branches sont solidaires d'une embase cylindrique à l'intérieur de laquelle pénètre l'extrémité inférieure du tube qui peut tourner dans ladite embase. Mais, l'embase et les branches sont généralement en acier soudé, ce qui pose des problèmes d'emballage et de transport, le poids de l'ensemble étant important. On connait également des piètements monobloc en aluminium qui pèsent moins lourd mais sont tout aussi encombrants.Currently, the branches are integral with a cylindrical base inside which penetrates the lower end of the tube which can rotate in said base. However, the base and the branches are generally made of welded steel, which poses packaging and transport problems, the weight of the assembly being significant. We also know monobloc aluminum legs which weigh less but are just as bulky.

a présente invention a pour objet de remédier à ces inconvénients, et a pour but de proposer un pied démontable qui puisse être aisément transporté et assemblé facilement sur place. A present invention aims to remedy these drawbacks, and aims to provide a removable foot which can be easily transported and assembled easily on site.

Selon la présente invention, le pied démontable pour meubles rotatifs, comprenant un tube pénétrant dans une embase solidaire de branches radiales, est caractérisé en ce que l'embase est constituée par un moyeu à l'intérieur duquel pénètre le tube, ledit moyeu comprenant des moyens d'assemblage de branches radiales. Les branches radiales peuvent ainsi être montées sur le moyeu.According to the present invention, the removable foot for rotating furniture, comprising a tube penetrating into a base secured to radial branches, is characterized in that the base is constituted by a hub inside which the tube penetrates, said hub comprising means for assembling radial branches. The radial branches can thus be mounted on the hub.

Selon une autre caractéristique de l'invention, la périphérie du moyeu présente des tenons longitudinaux à section en queue d'aronde, qui vont pénétrer à l'intérieur de mortaises fornées dans les branches du pied. L'assemblage ainsi conçu, n'exige aucun outil.According to another characteristic of the invention, the periphery of the hub has longitudinal tenons of dovetail section, which will penetrate inside mortises formed in the branches of the foot. The assembly thus designed requires no tools.

Selon encore une autre caractéristique de l'invention, des moyens de serrage à expansion sont montés à l'intérieur du tube pour bloquer l'extrémité inférieure dudit tube à l'intérieur du moyeu. Grâce à ce système, le meuble est parfaitement stabilisé.According to yet another characteristic of the invention, expansion clamping means are mounted inside the tube to block the lower end of said tube inside the hub. Thanks to this system, the furniture is perfectly stabilized.

D'autres caractéristiques et avantages de l'inven~ on apparaItront au cours de la description qui va suivre d'un mode particulier de réalisation, donné uniquement à titre d'exemple non limitatif, en regard des figures cri représentent - la figure 1, une vue éclatée d'un pied selon l'invention - la figure 2, une demi-coupe verticale d'un pied après
montage.Other characteristics and advantages of the invention will appear during the following description of a particular embodiment, given only by way of nonlimiting example, with reference to the Cree figures represent - FIG. 1, an exploded view of a foot according to the invention - Figure 2, a vertical half-section of a foot after
mounting.

Sur la figure 1, on voit du haut vers le bas, l'extrémité inférieure d'un tube 1 dont la seconde extrémité (non représentée) est solidaire du meuble ou du siège. Le tube 1 présente au moins deux ferres longitudinales diamétralement opposées 2, dont la fonction sera décrite ultérieurement. La hauteur de ces fentes est légèrement inférieure à la hauteur du moyeu. Au-dessous du tube 1 se trouve un moyeu ou embase 6.In Figure 1, we see from top to bottom, the lower end of a tube 1 whose second end (not shown) is secured to the furniture or seat. The tube 1 has at least two diametrically opposite longitudinal bars 2, the function of which will be described later. The height of these slots is slightly less than the height of the hub. Below the tube 1 is a hub or base 6.

Après montage, le tube 1 pénètre à l'intérieur de l'orifice borgne la prévu au centre de ce moyeu.After assembly, the tube 1 penetrates inside the blind orifice provided in the center of this hub.

A la périphérie du moyeu 6, s'étendent des tenons latéraux 10, normalement verticaux, qui pénètrent au montage dans des mortaises Il correspondantes prévues dans chacune des branches 7, dont une seule est représentée partiellement sur la figure.At the periphery of the hub 6 extend lateral tenons, normally vertical, which penetrate for mounting in corresponding mortises II provided in each of the branches 7, only one of which is shown partially in the figure.

Bien entendu, il faut qu'après montage tel que représenté sur la figure 2, le pied soit parfaitement rigide pour soutenir de manière équilibrée les charges qui lui seront appliquées et pour les répartir également sur l'ensemble des branches. A cet effet, on prévoit d'introduire à l'intérieur de l'orifice borgne la du moyeu 6, un plot de caoutchouc 5 qui sera emprisonné à l'intérieur du tube 1. Le but de ce plot est de serrer la partie inférieure du tube 1 contre la face interne du trou la de l'embase 6. Outre le plot, le moyen de serrage comprend une vis 8, un écrou 3 et des rondelles appropriées respectivement 4 et 9, disposées au-dessous de l'écrou 3 et au-dessus de la tête 14 de la vis 8. De préférence, l'écrou 3, la rondelle 4 et le plot 5 sont collés ensemble. L'ensemble est introduit dans le trou borgne la.Of course, after mounting as shown in Figure 2, the base must be perfectly rigid to support in a balanced manner the loads which will be applied to it and to distribute them equally over all of the branches. For this purpose, provision is made to introduce inside the blind hole of the hub 6, a rubber pad 5 which will be trapped inside the tube 1. The purpose of this pad is to tighten the lower part of the tube 1 against the internal face of the hole 1a of the base 6. In addition to the stud, the clamping means comprises a screw 8, a nut 3 and appropriate washers 4 and 9 respectively, arranged below the nut 3 and above the head 14 of the screw 8. Preferably, the nut 3, the washer 4 and the stud 5 are glued together. The assembly is introduced into the blind hole 1a.

,e montage d'un tel pied est aisé. 1 est livré chez '*tllisateur final en trois éléments qui sont d'une part le tube 1, les branches 7 et l'ensemble constitué par le moyeu 6, à ''intérieur duquel sont montés, sans être serrés, la vis 9, l'écrou 3, le plot 5 et les rondelles correspondantes. Dans *n premier temps, l'utilisateur dispose les branches 7 sur le moyeu 6 en faisant pénétrer les tenons 10 dans les mortaises 11. L'assemblage est ainsi effectif. Puis il introduit le tube 1 à l'intérieur de l'orifice la, dans lequel se trouve déjà le plot 5, la rondelle 4 et l'écrou 3.Par visage de la vis 8 dans l'écrou 3, la rondelle épaisse 4 écrase progressivement le plot de caoutchouc qui se déforme et vient appliquer la paroi extérieure du tube 1 fendu contre la paroi intérieure du trou borgne la, de manière à provoquer un serrage par écartement radial du tube. Au cours de ce vissage, la rondelle 9 et la tête de vis 14 pénètrent dans un logement 13 formé dans les branches 7, ces branches étant jointives au niveau de l'assemblage, de manière à être cachées après montage. Le système à expanser autorise l'utilisation de tubes fendus de différentes épaisseurs. Il est bien entendu facile de démonter ce pied par dévissage de la vis 8. , e mounting of such a foot is easy. 1 is delivered to '* final tllizer in three elements which are on the one hand the tube 1, the branches 7 and the assembly constituted by the hub 6, inside of which are mounted, without being tightened, the screw 9, the nut 3, the stud 5 and the corresponding washers. At first, the user places the arms 7 on the hub 6 by making the tenons 10 penetrate into the mortises 11. The assembly is thus effective. Then he introduces the tube 1 inside the orifice la, in which the stud 5, the washer 4 and the nut are already located. By the face of the screw 8 in the nut 3, the thick washer 4 gradually crushes the rubber pad which deforms and comes to apply the outer wall of the tube 1 split against the inner wall of the blind hole, so as to cause a clamping by radial spacing of the tube. During this screwing, the washer 9 and the screw head 14 penetrate into a housing 13 formed in the branches 7, these branches being contiguous at the assembly, so as to be hidden after assembly. The expanding system allows the use of split tubes of different thicknesses. It is of course easy to dismount this foot by unscrewing the screw 8.

En fonction du poids à supporter, le tube 1 peut être plus ou moins épais, ce qui ne change rien au fonctionnement qui vient d'être décrit. Par ailleurs, il est possible de disposer sur le moyeu 6 un nombre quelconque de branches 7 constituant le pied, branches qui peuvent porter à leur autre extrémité des roulettes ou des vérins.Depending on the weight to be supported, the tube 1 can be more or less thick, which does not change the operation which has just been described. Furthermore, it is possible to have on the hub 6 any number of branches 7 constituting the base, branches which can carry at their other end rollers or jacks.

Il va de soi que de nombreuses variantes peuvent être introduites, notamment par substitution de moyens techniquement équivalents sans pour autant sortir du cadre de l'invention. It goes without saying that many variants can be introduced, in particular by substitution of technically equivalent means without departing from the scope of the invention.
