Description

La présente invention concerne des perfectionnements apportés aux meubles comportant un plan de travail à niveau variable du type se composant d'une portion inférieure fixe et d'une portion supérieure mobile en hauteur, l'écart vertical entre lesdites portions résultant de la position relative d'au moins un couple de plans inclinés parallèles, solidaires respectivement desdites portions.The present invention relates to improvements made to furniture comprising a variable level worktop of the type consisting of a fixed lower portion and an upper portion movable in height, the vertical difference between said portions resulting from the relative position d 'at least a pair of parallel inclined planes, respectively integral with said portions.

De tels meubles sont connus dans leur principe et trouvent habituellement leur application dans le domaine des tables à dessiner et analogues.Such furniture is known in principle and usually finds its application in the field of drawing tables and the like.

L'invention vise de nouveaux aménagements à ces meubles en vue d'élargir leur domaine d'application, notamment aux tables-bureaux, grâce à de nouveaux moyens de réglage de la hauteur du plan de travail et de son immobilisation dans toute position relative par rapport à un piétement inférieur, par des moyens simples, peu coûteux et esthétiques.The invention relates to new arrangements for these pieces of furniture with a view to widening their field of application, in particular to office desks, by means of new means for adjusting the height of the worktop and its immobilization in any relative position by compared to a lower base, by simple, inexpensive and aesthetic means.

A cet effet, selon l'invention, le premier plan incliné comportant une rainure destinée au guidage du coulissement d'une nervure de dimensions correspondantes du second plan incliné, des logements, en nombre correspondant au nombre de positions relatives de la portion supérieure par rapport à la portion inférieure, sont pratiqués dans ladite nervure, tandis que dans ladite rainure est fixée une cheville de dimensions correspondant à celles desdits logements, la sélection de celui desdits logements dans lequel vient s'insérer ladite cheville, sélection qui détermine ledit écart vertical, résultant de la position de ladite cheville par rapport auxdits logements, tandis que le blocage dans cette position résulte de la position d'un curseur monté coulissant dans le plan incliné inférieur, des moyens solidaires de ladite portion supérieure permettant, depuis l'extérieur de ladite portion supérieure, l'immobilisation dudit curseur dans toute position choisie.To this end, according to the invention, the first inclined plane comprising a groove intended for guiding the sliding of a rib of corresponding dimensions of the second inclined plane, housings, in number corresponding to the number of relative positions of the upper portion relative to to the lower portion, are made in said rib, while in said groove is fixed a pin of dimensions corresponding to those of said housings, the selection of that of said housings in which comes inserting said peg, selection which determines said vertical deviation, resulting from the position of said peg relative to said housings, while blocking in this position results from the position of a slider mounted to slide in the lower inclined plane, means integral with said upper portion allowing, from outside of said upper portion, the immobilization of said cursor in any chosen position.

Dans la pratique, ledit curseur est de préférence un écrou prisonnier dans une coulisse pratiquée dans ladite nervure, et lesdits moyens de blocage consistent en un boulon vissé en permanence mais à un degré variable dans cet écrou et dont la tête est accessible depuis le dessus de ladite portion supérieure, le dévissage de ce boulon autorisant le déplacement desdites portions par coulissement des deux plans inclinés l'un par rapport à l'autre, ladite cheville étant hors desdits logements et son vissage déterminant leur blocage en toute position, ladite cheville étant insérée dans l'un desdits logements.In practice, said slider is preferably a captive nut in a slide made in said rib, and said locking means consist of a bolt which is permanently screwed but to a variable degree in this nut and the head of which is accessible from above. said upper portion, the unscrewing of this bolt allowing said portions to be displaced by sliding the two inclined planes relative to each other, said pin being outside of said housings and its screwing determining their blocking in any position, said pin being inserted in one of said dwellings.

Selon une réalisation , les axes desdits logements, de la cheville et dudit boulon sont parallèles entre eux et perpendiculaires auxdits plans inclinés, et ladite nervure est pratiquée dans ladite portion inférieure, et dans ladite nervure est vissée une platine comportant lesdits logements et la coulisse emprisonnant l'écrou, tandis que dans la portion supérieure présentant la rainure est d'une part vissée une platine à laquelle est soudée ladite cheville, et d'autre part pratiqué un passage pour ledit boulon, de manière que la tête de ce dernier soit accessible depuis l'extérieur de la portion supérieure du meuble.According to one embodiment, the axes of said housings, of the dowel and of said bolt are mutually parallel and perpendicular to said inclined planes, and said rib is formed in said lower portion, and in said rib is screwed a plate comprising said housings and the trapping slide the nut, while in the upper portion having the groove is on the one hand screwed a plate to which said dowel is welded, and on the other hand made a passage for said bolt, so that the head of the latter is accessible from outside the upper portion of the cabinet.

Comme il a été indiqué dans le préambule, grâce à ces aménagements, il est possible de réaliser de nouveaux modèles de tables-bureaux dont la portion supérieure constitue le plan de travail et la (les) portions(s) inférieure(s) constitue(nt) le(s) piétement(s).As indicated in the preamble, thanks to these arrangements, it is possible to produce new models of desk-tables, the upper portion of which constitutes the work surface and the lower portion (s) constitutes ( nt) the base (s).

Dans ce cas, les plans inclinés sont pratiqués sur le champ de panneaux verticaux respectivement solidaires du plan de travail et des piétements.In this case, the inclined planes are made on the field of vertical panels respectively secured to the work surface and the legs.

On va maintenant décrire l'invention plus en détail, en se référant au dessin annexé, qui représente un mode de réalisation préférentiel de l'invention, et sur lequel :

  • La figure 1 est une vue en perspective d'une table-bureau aménagée selon l'invention pour comporter plusieurs plans de travail à niveau réglable.
  • La figure 2 est une vue de profil illustrant le montage du plan de travail selon l'invention.
  • La figure 3 illustre en perspective les éléments du mécanisme de réglage, à l'état réuni.
  • La figure 4 illustre les mêmes éléments à l'état séparé.
  • La figure 5 est une coupe longitudinale montrant la coopération entre lesdits éléments.
  • Les figures 6, 7 et 8 sont des coupes transversales suivant VI-VI, VII-VII, VIII des figures 2 et 5.
The invention will now be described in more detail, with reference to the accompanying drawing, which represents a preferred embodiment of the invention, and in which:
  • Figure 1 is a perspective view of a desk table arranged according to the invention to include several worktables with adjustable level.
  • Figure 2 is a side view illustrating the mounting of the work surface according to the invention.
  • Figure 3 illustrates in perspective the elements of the adjustment mechanism, in the assembled state.
  • Figure 4 illustrates the same elements in a separate state.
  • Figure 5 is a longitudinal section showing the cooperation between said elements.
  • Figures 6, 7 and 8 are cross sections along VI-VI, VII-VII, VIII of Figures 2 and 5.

Ainsi qu'il apparaît tout d'abord aux figures 1 et 2, la table-bureau, selon l'invention, présente deux plans de travail d'orientation perpendiculaire A et B réunis par un plateau d'angle C. Chaque zone A ou B comporte une portion inférieure fixe 1 jouant le rôle de piétement, et une portion supérieure 2 portant le plan de travail H horizontal réglable en hauteur selon les besoins de l'utilisateur.As it appears first of all in FIGS. 1 and 2, the desk table, according to the invention, has two work planes of perpendicular orientation A and B joined by a tray of angle C. Each zone A or B comprises a fixed lower portion 1 playing the role of a base, and an upper portion 2 carrying the horizontal worktop H adjustable in height according to the needs of the user.

Dans les meubles de ce genre, il est connu d'utiliser pour ce réglage des systèmes mécaniques coûteux et compliqués, tels que des couples pignon/crémaillère, pour permettre de modifier ce réglage de façon relativement fréquente, alors que pour la plupart des meubles visés dans la présente invention, il ne convient d'effectuer un réglage du niveau que de temps en temps, par exemple en cas de changement d'utilisateur.In furniture of this kind, it is known to use for this adjustment expensive and complicated mechanical systems, such as pinion / rack pairs, to allow this adjustment to be modified relatively frequently, whereas for most of the furniture targeted in the present invention, it is only appropriate to carry out a level adjustment from time to time, for example in the event of a change of user.

C'est dans cet esprit qu'a été conçu le système selon l'invention.It is in this spirit that the system according to the invention was designed.

De manière connue dans son principe, ce système donc se compose d'un couple de plans inclinés, l'un désigné par 3, étant pratiqué sur le dessus du piétement 4 et l'autre, désigné par 5, pratiqué sur le dessous de la portion supérieure 2 portant le plan de travail H. Les plans inclinés 3 et 5 sont parallèles et glissent l'un sur l'autre, en déterminant l'écart variable entre les portions 1 et 2.In known manner in principle, this system therefore consists of a couple of inclined planes, one designated by 3, being practiced on the top of the base 4 and the other, designated by 5, practiced on the bottom of the upper portion 2 carrying the work plane H. The inclined planes 3 and 5 are parallel and slide one over the other, determining the variable distance between the portions 1 and 2.

Le guidage de ce glissement résulte de la coopération entre une nervure 6 pratiquée dans le plan incliné inférieur 3, et une rainure 7, pratiquée dans le plan incliné supérieur 5.The guidance of this sliding results from the cooperation between a rib 6 formed in the lower inclined plane 3, and a groove 7, formed in the upper inclined plane 5.

Selon l'invention, dans ladite nervure 6 sont pratiqués des logements 8, en nombre correspondant au nombre de positions relatives prévues pour la portion supérieure 2 par rapport à la portion inférieure 1, tandis que dans ladite rainure 7 est fixée une cheville 9 de dimensions correspondant à celles desdits logements 8, la sélection de celui desdits logements 8 dans lequel vient s'insérer ladite cheville 9 déterminant l'écart vertical entre les portions 1 et 2, et donc la hauteur du plan de travail H. Selon l'invention également, dans ledit plan incliné inférieur 3 est pratiquée une lumière 10 formant coulisse longitudinale dans laquelle peut coulisser un écrou prisonnier 11, vissé en permanence, mais à un degré variable, sur l'extrémité avant d'un boulon 12, traversant un passage 13 pratiqué à travers la portion supérieure 2 de manière que sa tête 14 soit accessible depuis l'arrière de ladite portion supérieure. Le rôle du couple écrou 11/boulon 12 est d'immobiliser le système, une fois le téton 9 en place dans le logement 8 choisi, en bloquant l'écrou 11 en un emplacement longitudinal déterminé de la lumière 10.According to the invention, in said rib 6 are formed housings 8, in a number corresponding to the number of relative positions provided for the upper portion 2 relative to the lower portion 1, while in said groove 7 is fixed a dowel 9 of dimensions corresponding to those of said housings 8, the selection of that of said housings 8 into which is inserted said peg 9 determining the vertical difference between the portions 1 and 2, and therefore the height of the work surface H. According to the invention also, in said a lower inclined plane 3 is formed a light 10 forming a longitudinal slide in which can slide a captive nut 11, permanently screwed, but to a variable degree, on the front end of a bolt 12, passing through a passage 13 made through the upper portion 2 so that its head 14 is accessible from the rear of said upper portion. The role of the nut 11 / bolt 12 couple is to immobilize the system, once the stud 9 in place in the housing 8 chosen, by blocking the nut 11 in a determined longitudinal location of the light 10.

Quand le boulon 12 est dévissé pour sortir de l'écrou 11, alors il est possible de soulever la portion supérieure 2 en extrayant le téton 9 de son logement, pour l'insérer dans un autre logement, en modifiant ainsi l'écart entre les portions 1 et 2, donc la hauteur du plan de travail. Au contraire, quand il est vissé à fond dans l'écrou 11, alors le blocage est assuré.When the bolt 12 is unscrewed to come out of the nut 11, then it is possible to lift the upper portion 2 by extracting the stud 9 from its housing, to insert it into another housing, thereby modifying the distance between the portions 1 and 2, so the height of the worktop. On the contrary, when it is fully screwed into the nut 11, then the blocking is ensured.

Dans la pratique, le meuble étant de préférence réalisé en bois, la portion de la nervure 6 comportant les logements 8 et la lumière 10 est renforcée par une platine métallique 15, tandis que, de même, la portion de la rainure 7 située au-dessus de ladite platine 15 est elle-même obturée par une autre platine métallique 16 sur laquelle est soudée la cheville 9, et perforée pour permettre le passage du boulon 12. Les platines 15 et 16 sont encastrées dans le bois des plans inclinés 3 et 5 et fixées par exemple par collage ou au moyen de vis (non représentées).In practice, the piece of furniture preferably being made of wood, the portion of the rib 6 comprising the housings 8 and the opening 10 is reinforced by a metal plate 15, while, likewise, the portion of the groove 7 situated above above said plate 15 is itself closed by another metal plate 16 on which the pin 9 is welded, and perforated to allow the passage of the bolt 12. The plates 15 and 16 are embedded in the wood of the inclined planes 3 and 5 and fixed for example by gluing or by means of screws (not shown).

Il est clair que, pour pouvoir se déplacer sur toute la longueur de la platine 15, en fonction du réglage choisi, la platine 16 doit être plus courte, sa longueur étant déterminée par le débattement maximum du plan incliné supérieur sur le plan incliné inférieur, c'est à dire la distance entre les logements 8 extrêmes. La longueur de la lumière 10 sera d'ailleurs égale à la longueur de ladite platine 16, ainsi définie.It is clear that, in order to be able to move over the entire length of the plate 15, according to the chosen setting, the plate 16 must be shorter, its length being determined by the maximum clearance of the upper inclined plane on the lower inclined plane, that is to say the distance between the extreme housings 8. The length of the light 10 will moreover be equal to the length of said plate 16, thus defined.

Ainsi qu'on le voit sur les figures, tous les axes des logements 8, de la cheville 9, de l'écrou 11 et du boulon 12 sont parallèles entre eux, et donc perpendiculaires aux deux plans inclinés 3 et 5, ce qui assure la meilleure répartition des efforts de cisaillement et donc la plus grande solidité à l'accrochage des portions 1 et 2 l'une à l'autre dans leurs diverses positions.As can be seen in the figures, all the axes of the housings 8, of the pin 9, of the nut 11 and of the bolt 12 are parallel to each other, and therefore perpendicular to the two inclined planes 3 and 5, which ensures the better distribution of the shear forces and therefore the greater solidity in the attachment of the portions 1 and 2 to each other in their various positions.

Comme on le voit également, l'unique élément mécanique du système visible de l'extérieur du meuble est la tête de boulon 14, dont la seule manoeuvre est suffisante pour permettre le réglage du meuble en hauteur. A l'inverse, on peut considérer que la forme en triangles de chaque piétement et la coopération entre les deux plans inclinés participent à l'esthétique du meuble, comme il ressort en particulier de la figure 1.As can also be seen, the only mechanical element of the system visible from the outside of the cabinet is the bolt head 14, the single operation of which is sufficient to allow the cabinet to be adjusted in height. Conversely, we can consider that the triangular shape of each base and the cooperation between the two inclined planes contribute to the aesthetics of the furniture, as is shown in particular in Figure 1.

Bien entendu, l'invention n'est pas limitée à son application aux tables-bureaux comme il vient d'être décrit, mais peut être adaptée à tout ensemble dont une portion supérieure peut prendre plusieurs hauteurs par rapport à une portion inférieure fixe.Of course, the invention is not limited to its application to tables-desks as it has just been described, but can be adapted to any assembly of which an upper portion can take several heights compared to a fixed lower portion.
