Description
La présente invention concerne les chaises ou fauteuils avec un siège et/ou un dossier munis d'un dispositif de support à position variable, et plus en particulier un système de montage d'un levier basculant destiné à commander le dispositif qui règle la position de la chaise ou du fauteuil.The present invention relates to chairs or armchairs with a seat and / or a backrest provided with a support device with variable position, and more particularly a system for mounting a tilting lever intended to control the device which regulates the position of the chair or armchair.
Comme on sait bien, dans les chaises ou fauteuils du type susmentionné, le siège est fixé sur une plaque appliquée au sommet d'un montant extensible en hauteur fixé à la base d'appui et normalement constitué d'un ressort à gaz ou d'autre dispositif à ressort équivalent.As is well known, in chairs or armchairs of the aforementioned type, the seat is fixed on a plate applied to the top of a stretchable upright fixed to the support base and normally consisting of a gas spring or other equivalent spring device.
L'extension du montant destiné à l'ajustage de l'hauteur du siège est réglé par un levier basculant et pivotant dans la plaque d'appui ou dans un organe lui connecté pour pouvoir agir sur les moyens de blocage/déblocage du dispositif de réglage. Jusqu'à maintenant plusieurs systèmes pour le montage du levier ont été proposé, mais ils sont tous bien compliqués et coûteux, attendu qu'ils demandent des opérations et des outils spéciaux et présentent aussi des problèmes à l'assemblage.The extension of the amount intended for the adjustment of the height of the seat is adjusted by a rocking and pivoting lever in the support plate or in a member connected thereto in order to be able to act on the means of locking / unlocking of the adjustment device. Until now, several systems for mounting the lever have been proposed, but they are all very complicated and expensive, since they require special operations and tools and also present assembly problems.
Le but de l'invention est partant ce de resoudre ces problèmes et d'éliminer les inconvénients et les désavantages des réalisations proposés jusqu'à maintenant.The object of the invention is therefore to solve these problems and to eliminate the drawbacks and disadvantages of the embodiments proposed up to now.
Dans ce but l'invention prévoit un montage aisé et rapide du levier pivotant sur la plaque d'appui sans l'aide d'outils particuliers et sans aucune opération compliquée. En effet, selon l'invention le levier basculant est simplement introduit dans un trou transversal percé dans un cylindre tournant qui sert de goupille tournante, préalablement monté sur la plaque d'appui de la chaise. Le levier basculant d'un côté et le trou transversal de la goupille de l'autre côté ont des sections complémentaires pour s'accoupler sans que le levier puisse tourner dans le trou susdit, tout en pouvant basculer avec la goupille autour de son axe. L'assemblage entre la goupille et le levier basculant est assuré, en direction axiale, par une partie de la plaque attenant au trou transversal de la goupille et destinée à intercepter au moins une saillie du levier pour en empêcher la sortie et le désaccouplement de la goupille.To this end, the invention provides easy and quick mounting of the pivoting lever on the support plate without the aid of special tools and without any complicated operation. Indeed, according to the invention the tilting lever is simply introduced into a transverse hole drilled in a rotating cylinder which serves as a rotating pin, previously mounted on the support plate of the chair. The tilting lever on one side and the transverse hole of the pin on the other side have complementary sections for coupling without the lever being able to rotate in the aforementioned hole, while being able to tilt with the pin around its axis. The assembly between the pin and the rocking lever is ensured, in the axial direction, by a part of the adjoining plate to the transverse hole of the pin and intended to intercept at least one projection of the lever to prevent the output and uncoupling of the pin.
Le système de montage qui forme l'objet de l'invention est donc caractérisé en ce que la plaque d'appui du siège est munie d'une fente en T, que sur cette plaque, près de la fente en T susdite, un élément cylindrique fonctionnant comme une goupille et ayant un trou transversal avec au moins un trou transversal avec au moins un creux radial, et en ce que le levier basculant présente au moins une saillie latérale en correspondance au creux radial de l'élément cylindrique, le levier étant conjugué, par enfilement, avec le trou transversal de l'élément cylindrique à travers de la partie la plus large de la fente en T, les côtés de la partie étroite de la fente en T interceptant la saillie latérale pour empêcher le désaccouplement du levier.The mounting system which forms the object of the invention is therefore characterized in that the seat support plate is provided with a T-slot, that on this plate, near the above-mentioned T-slot, an element cylindrical functioning as a pin and having a transverse hole with at least one transverse hole with at least one radial recess, and in that the rocking lever has at least one lateral projection corresponding to the radial recess of the cylindrical element, the lever being conjugated, by threading, with the transverse hole of the cylindrical element through the widest part of the T-slot, the sides of the narrow part of the T-slot intercepting the lateral projection to prevent uncoupling of the lever.

En Fig. 1 du dessin le nombre 10 indique la base d'une chaise ou d'un fauteuil sur laquelle est fixé le montant 11, par exemple sous forme d'un ressort à gaz ou autre dispositif équivalent et extensible en hauteur, son sommet portant une plaque d'appui 12 pour le siège 13 et aussi pour le dossier 14, l'extension du montant 11 étant contrôlée, d'une manière connue, par un levier 15.In Fig. 1 of the drawing the
Selon l'invention, le levier basculant 15 est monté sur la plaque 12 au moyen d'un élément cylindrique 16 ayant la fonction d'une goupille. Plus précisément, la plaque 12 présente, dans une position appropriée, une fente en T, vis-àa-vis de laquelle et à l'intérieur de la plaque 12 pivote l'élément cylindrique 16. Ce dernier présente, pour se trouver, quand il est monté, en correspondance à la fente en T de la plaque 12, un trou transversal 18 avec un creux radial 19, L'élément cylindrique 16 est arrêté sur la plaque 12 au moyen d'un cavalier 22 dont l'oeillet 21 se trouve en correspondance au trou 18 de l'élément cylindrique 16.According to the invention, the
Quant au levier basculant 15, il présente une section analogue à celle du trou transversal 18 de l'élément cylindrique 16 et il est muni d'au moins une saillie latérale 22 destinée à se conjuguer avec le creux radial du trou 18 susdit.As for the
Enfin, il faut remarquer que la fente en T 17 de la plaque 12 comprend une partie étroite ayant une largeur un peu supérieure à la section du levier 15 et una partie plus large pour permettre le passage du levier 15 avec sa ou ses saillies latérales 22.Finally, it should be noted that the T-
Pour monter le levier 15 il faut tourner l'élément cylindrique 16 ou la goupille en utilisant, par exemple, l'extrémité du levier lui-même, jusqu'à ce que son trou transversal va se trouver en ligne à la partie la plus large de la fente en T de la plaque 12.To mount the
En cette situation, le levier 15 peut être enfilé, à travers la fente 17, dans le trou 18 de l'élément cylindrique 16, jusqu'à ce que une des ses saillies latérales 22 s'enfonce dans le creux radial 19 du trou 18 et de telle manière que l'extrémité du levier s'accouple avec le dispositif 11 à commander. A ce point, le levier 15 et l'élément cylindrique 16 sont couplés et on peut les déplacer angulairement autour de l'axe de la goupille. Partant, le levier peut être déplacé dans la partie étroite de la fente en T 17, dont les côtés vont intercepter la ou les saillies latérales 22 pour empêcher le défilement et donc le démontage du levier, même en permettant les déplacements opératoires du levier lui-même.In this situation, the
Dans la description ci-dessus référence a été fait à un levier basculant destiné à commander un dispositif extensible en hauteur pour soulever ou abaisser le siège; cependant, le système de montage objet de l'invention peut être utilisé advantageusement et sans sortir de son but, pour tout autre levier basculant destiné à actionner des dispositifs différents prévus pour le réglage des chaises ou des fauteuils et aussi pour des autres applications et fonctions.In the description above reference has been made to a tilting lever intended to control a height-extendable device for raising or lowering the seat; however, the mounting system object of the invention can be used advantageously and without departing from its purpose, for any other rocking lever intended to actuate different devices provided for the adjustment of chairs or armchairs and also for other applications and functions .
