Description

La présente invention a pour objet un mécanisme qui permet de modifier et de régler la hauteur des accoudoirs des fauteuils. Elle trouve son application dans le domaine des fauteuils de bureau.The present invention relates to a mechanism which makes it possible to modify and adjust the height of the armrests of armchairs. It finds its application in the field of office chairs.

Le principal but de la présente invention est celui d'équiper les fauteuils de bureau d'accoudoirs que l'on peut aussi régler en hauteur, en plus des réglages normalement prévus par l'état de la technique.The main purpose of the present invention is to equip office chairs with armrests which can also be adjusted in height, in addition to the adjustments normally provided for in the prior art.

Un autre but de la présente invention est celui de fournir un mécanisme de réglage en hauteur des accoudoirs des fauteuils particulièrement simple et efficace, constitué d'un nombre limité de composants, non encombrant pour ne pas nuire à l'esthétique du fauteuil, facilement accessible, d'utilisation facile et pouvant être actionné sans se lever.Another object of the present invention is to provide a particularly simple and effective mechanism for adjusting the armrest of armchairs, consisting of a limited number of components, not bulky so as not to harm the aesthetics of the chair. easy accessible chair, easy to use and can be operated without getting up.

Le mécanisme objet de la présente invention est essentiellement conforme à la revendication 1. Il consiste fondamentalement en une crémaillère fixe à direction verticale qui interagit avec une manette de blocage/déblocage que l'on peut commander au moyen d'un bouton-poussoir, qui est montée sur une pièce qui soutient le support et que l'on peut déplacer en hauteur en fonction de la crémaillère.The mechanism object of the present invention is essentially according to claim 1. It basically consists of a fixed rack in vertical direction which interacts with a locking / unlocking handle which can be controlled by means of a push button, which is mounted on a part which supports the support and which can be moved in height depending on the rack.

L'interaction de la manette de blocage/déblocage avec la crémaillère permet de positionner l'accoudoir sur autant de positions différentes qu'il y a de dents dans la crémaillère, et permet ainsi de satisfaire de nombreuses exigences de positionnement des accoudoirs.The interaction of the locking / unlocking lever with the rack makes it possible to position the armrest in as many different positions as there are teeth in the rack, and thus makes it possible to satisfy many requirements for positioning the armrests.

Plus de détails résulteront évidents grâce à la description suivante et aux dessins ci-joints; dans ceux-ci:

  • la Fig. 1 montre, en section verticale, l'accoudoir et le mécanisme de réglage en hauteur,
  • la Fig. 2 montre une section transversale selon les flèches II-II de la Fig. 1, et
  • la Fig. 3 montre une autre section selon les flèches III-III de la Fig. 1.
More details will be evident from the following description and the attached drawings; in these:
  • Fig. 1 shows, in vertical section, the armrest and the height adjustment mechanism,
  • Fig. 2 shows a cross section according to arrows II-II of FIG. 1, and
  • Fig. 3 shows another section according to arrows III-III of FIG. 1.

Dans ces dessins, le n°10 indique l'accoudoir d'un fauteuil qui est monté et fixé en haut d'un support 11 tubulaire, de section elliptique, que l'on peut déplacer verticalement et qui est introduit dans un montant de support fixe 12. Ce montant 12 s'étend vers le haut à partir, normalement, du niveau de l'assise - non représentée - du fauteuil, avec des éléments de guidage 13 à l'intérieur du support 11 et de l'accoudoir 10.In these drawings, n ° 10 indicates the armrest of a armchair which is mounted and fixed at the top of a tubular support 11, of elliptical section, which can be moved vertically and which is introduced into a fixed support upright 12. This upright 12 extends upwards from, normally, from the level of the seat - not shown - of the chair, with guide elements 13 inside the support 11 and the armrest 10.

Conformément à la présente invention, dans le montant fixe 12 on a exécuté une crémaillère 14 le long d'un côté vertical d'une fente oblongue 15 qui s'étend selon la hauteur du montant.According to the present invention, in the fixed upright 12 a rack 14 has been executed along a vertical side of an oblong slot 15 which extends along the height of the upright.

Dans le support 11 de l'accoudoir 10, est montée sur pivot intermédiaire 16', une manette oscillante 16 de blocage/déblocage. Cette manette oscillante 16 présente une extrémité inférieure munie d'un téton d'arrêt 17, et une extrémité supérieure articulée avec un bouton-poussoir de commande 18. Le téton d'arrêt 17 coulisse dans la fente verticale 15 et s'engage dans la denture à crémaillère 14. Le bouton-poussoir de commande 18 dépasse transversalement de l'accoudoir et se trouve justement au-dessous de celui-ci. Un ressort de rappel 19, relié au bouton-poussoir 18 comme montre la Fig. 1, ou bien à la manette oscillante 16, maintient normalement déplacée la manette de façon à ce que le téton d'arrêt 17 s'engage constamment dans la denture 14.In the support 11 of the armrest 10, is mounted on an intermediate pivot 16 ', an oscillating lever 16 for locking / unlocking. This oscillating lever 16 has a lower end provided with a stop pin 17, and an upper end articulated with a control push button 18. The stop pin 17 slides in the vertical slot 15 and engages in the rack and pinion 14. The control push-button 18 protrudes transversely from the armrest and is located just below it. A return spring 19, connected to the push button 18 as shown in FIG. 1, or alternatively with the oscillating joystick 16, keeps the joystick normally moved so that that the stop pin 17 constantly engages in the teeth 14.

Les dents de la crémaillère 14 permettent de positionner l'accoudoir sur autant de positions sur le montant, c'est-à-dire au-dessus de l'assise. Pour effectuer le réglage, il suffit de déplacer la manette oscillante 16, au moyen du bouton-poussoir 18, de façon à éloigner et à désengager le téton 17 de la denture 14, puis faire coulisser le support 11 et donc l'accoudoir sur le montant 12 jusqu'à l'obtention de la hauteur désirée.
A ce moment, on relâche le bouton-poussoir 18; la manette 16, grâce au ressort 19, se déplace à nouveau jusqu'à ce que le téton d'arrêt 17 s'engage dans les dents au niveau correspondant. L'opération est pratique et de simple exécution, et on peut l'effectuer sans se lever.The teeth of the rack 14 make it possible to position the armrest in as many positions on the upright, that is to say above the seat. To carry out the adjustment, it suffices to move the oscillating lever 16, by means of the push button 18, so as to distance and disengage the stud 17 from the teeth 14, then slide the support 11 and therefore the armrest on the amount 12 until the desired height is obtained.
At this time, the push button 18 is released; the lever 16, thanks to the spring 19, moves again until the stop pin 17 engages in the teeth at the corresponding level. The operation is practical and simple to perform, and you can do it without getting up.
