Description

L'objet de l'invention est un système de blocage pour tiroirs de meubles, de ceux qui possèdent un boulon uni au tiroir ; ce boulon actionne un dispositif de blocage. Tous ces dispositifs de blocage sont corrélés entre eux au moyen d'une platine-base fixée au meuble et peuvent se déplacer de façon bidirectionnelle sur la platine-base.The object of the invention is a locking system for furniture drawers, those who have a bolt connected to the drawer; this bolt actuates a locking device. All these locking devices are correlated to each other by means of a base plate attached to the cabinet and can move bidirectionally on the base plate.

Dans l'état actuel de la technique, il existe divers systèmes de blocage pour tiroirs de meubles, comme ceux qui, lorsque l'un des tiroirs est ouvert, déclenchent la fermeture autobloquante des autres tiroirs, pour éviter ainsi le basculement du meuble. En particulier, le brevet EP1059408 , du même Demandeur, décrit un système de blocage pour ceux qui ont, uni au tiroir, un boulon qui actionne le dispositif de blocage correspondant ; tous ces dispositifs sont corrélés entre eux au moyen d'une platine- base fixée au meuble et sur laquelle :

  1. a) sont montés plusieurs modules-support avec des dispositifs pour se déplacer, longitudinalement et de façon bidirectionnelle. Chaque module fixe un dispositif de blocage, avec des dispositifs pour son propre verrouillage ouvert ou fermé, en appliquant un effort linéaire d'une direction angulaire par rapport au déplacement du tiroir,
  2. b) la direction de l'application de l'effort linéaire est orthogonale à la direction de déplacement du tiroir.
In the current state of the art, there are various locking systems for furniture drawers, such as those that, when one of the drawers is open, trigger the self-locking closure of other drawers, to prevent the tilting of the furniture. In particular, the patent EP1059408 , of the same Applicant, describes a locking system for those who have, together with the drawer, a bolt which actuates the corresponding locking device; all these devices are correlated with one another by means of a base plate fixed to the furniture and on which:
  1. a) are mounted a plurality of support modules with devices for moving longitudinally and bidirectionally. Each module fixes a locking device, with devices for its own open or closed lock, by applying a linear force of an angular direction relative to the movement of the slide,
  2. b) the direction of the application of the linear force is orthogonal to the direction of movement of the slide.

Le Brevet US7144092 divulgue un système de blocage pour tiroirs de meubles, de ceux qui possèdent un boulon uni à un tiroir actionnant un dispositif de blocage. Tous ces dispositifs sont corrélés entre eux au moyen d'une platine-base fixée au meuble et peuvent se déplacer de façon bidirectionnelle sur la platine-base dans lequel chaque dispositif de blocage est composé par, un levier, que doit être actionné par un boulon incorporé á un élément monobloc avec une surface de came (surface inclinée au dessus de l'élément monobloc) pour le boulon et un élément saillant à l'arrière en "T" pour pouvoir se déplacer sur la platine-base, et les éléments monoblocs s'ajustent entre eux; de façon à ce qu'en ouvrant un tiroir, le boulon correspondant actionne à chaque fois un levier de l'un des dispositifs de blocage.The patent US7144092 discloses a locking system for furniture drawers, from those having a bolt to a drawer actuating a locking device. All these devices are correlated with one another by means of a base plate fixed to the furniture and can move bidirectionally on the base plate in which each locking device is composed by a lever, which must be actuated by a bolt. incorporated in a monobloc element with a cam surface (inclined surface above the monobloc element) for the bolt and a protruding element at the back in "T" to be able to move on the base plate, and the monobloc elements adjust between them; so that by opening a drawer, the corresponding bolt actuates each time a lever of one of the locking devices.

Dans le système du Brevet US7144092 , la distance entre les éléments monobloc est variable, et en conséquence toute perturbation, pour défaut ou d'usure, dans une des éléments du dispositif de blocage, fait que le boulon n'actionne pas le dispositif de blocage.In the patent system US7144092 , the distance between the monoblock elements is variable, and consequently any disturbance, for lack or wear, in one of the elements of the locking device, causes the bolt does not actuate the locking device.

Dans le Brevet DE19527848 est décrit un armoire dan lequel, les tiroirs peuvent être retirés par des unités de retrait télescopiques fixées sur les parois latérales de l'armoire et portent un élément d'accouplement qui peut entrer en connexion efficace avec un élément de commande d'un dispositif de fermeture fixé sur une paroi latérale du armoire. Charge tiroir a une hauteur multiple par d'une hauteur basic. Le dispositif de fermeture comporte un rail de base avec une hauteur, ce qui correspond au nombre d'unités de hauteur déterminées par les tiroirs. Sur le rail de base (10), un nombre de glissières identiques (20) qui correspond aux tiroirs de double hauteur sont agencées. Un seul chemin de positionnement prédéterminé vers le haut sur le rail de base est prévu pour les unités glissières.In the patent DE19527848 there is described a cabinet in which the drawers can be removed by telescopic removal units attached to the side walls of the cabinet and carry a coupling element which can effectively connect to a control element of a control device. closure fixed on a side wall of the cabinet. Drawer load has a multiple height by a basic height. The closure device comprises a base rail with a height, which corresponds to the number of height units determined by the drawers. On the base rail (10), a number of identical slides (20) corresponding to the double height drawers are arranged. Only one predetermined positioning path upward on the base rail is provided for the slide units.

Le problème est résolu par le système selon l'invention.The problem is solved by the system according to the invention.

Dans la demande la distance entre les éléments monobloc est constante parce que les éléments monobloc font butées entre eux.In the application, the distance between the one-piece elements is constant because the one-piece elements abut each other.

Aussi dans la demande les éléments du système sont dimensionnés en fonction de la hauteur du monobloc.Also in the request the elements of the system are dimensioned according to the height of the monobloc.

Le système de blocage, selon l'invention, supprime le besoin d'inclure les modules-supports précités puisque dispositif de blocage lui-même incorpore les éléments pour se déplacer longitudinalement sur la platine-base.The locking system according to the invention eliminates the need to include the aforementioned support modules since the locking device itself incorporates the elements to move longitudinally on the base plate.

Voici la description d'un exemple de réalisation pratique, non limitatif, de la présente invention :
Selon l'invention, le système de blocage pour tiroirs de meubles, employé surtout pour les meubles de bureau et similaires, assemble, en corrélation avec tous les tiroirs (C) d'un meuble (M), une platine-base (1), ou un autre système de guidage équivalent, fixée à son tour au meuble par des moyens (M) connus.Here is the description of an exemplary practical, non-limiting embodiment of the present invention:
According to the invention, the locking system for furniture drawers, used mainly for office furniture and the like, assembles, in correlation with all the drawers (C) of a piece of furniture (M), a platinum-base (1) , or another equivalent guiding system, in turn fixed to the furniture by means (M) known.

Sur la dite platine-base, plusieurs dispositifs de blocage (D) peuvent se déplacer de façon linéaire et bidirectionnelle.On said platinum-base, several locking devices (D) can move linearly and bidirectionally.

À chaque tiroir (C) du meuble (M), correspond un boulon (B).At each drawer (C) of the cabinet (M), there is a bolt (B).

Ce système, selon l'invention, doit être complété; par exemple, par des éléments fixés sur la partie supérieure des dispositifs de blocage (D) pour qu'ils restent à leur place et par d'autres éléments qui doivent bloquer l'ensemble en position de verrouillage. Ces éléments ne font pas l'objet de cette invention.This system according to the invention must be completed; for example, by elements fixed on the upper part of the locking devices (D) so that they remain in their place and by other elements which must lock the assembly in the locking position. These elements are not the subject of this invention.

Selon l'invention, la hauteur (H) des tiroirs (C) du meuble (M) doit toujours être multiple d'une dimension prédéterminée (d1); c'est-à-dire que la dimension prédéterminée (d1) est multipliée autant de fois (par un nombre entier) pour chaque hauteur (H) de chaque tiroir (C); cela fonctionne avec tous les tiroirs (C) quelle que soit la hauteur de chaque tiroir (C)- qui peut être la même (H) pour tous les tiroirs (C) ou différente -(H1), (H2), (H3) pour un ou plusieurs tiroirs- figure 4.According to the invention, the height (H) of the drawers (C) of the cabinet (M) must always be multiple of a predetermined dimension (d 1 ); that is to say, the predetermined dimension (d 1) is multiplied many times (by an integer) for each height (H) of each drawer (C); it works with all drawers (C) regardless of the height of each drawer (C) - which can be the same (H) for all drawers (C) or different - (H 1 ), (H 2 ), ( H 3 ) for one or more drawers- figure 4 .

Chaque dispositif de blocage (D) est composé d'un levier (3), actionné par le boulon (B) du tiroir (C) correspondant; d'un élément monobloc (10) qui définit une surface de came (20) pour ledit boulon (B) ; et d'une partie saillante (40) en forme de « T » qui sert de guidage pour son déplacement sur la platine-base (1).Each locking device (D) is composed of a lever (3), actuated by the bolt (B) of the corresponding drawer (C); a one-piece member (10) defining a cam surface (20) for said bolt (B); and a protruding portion (40) in the form of a "T" which serves as a guide for its displacement on the base plate (1).

La dimension prédéterminée (d1) est, à son tour, multiple de la hauteur (m) de chaque élément monobloc.The predetermined dimension (d 1 ) is, in turn, multiple of the height (m) of each monoblock element.

Le boulon (B) est placé à une certaine distance (Z) du bord inférieur du tiroir (C). Cette distance (Z) est multiple de la hauteur (m) de chaque élément monobloc (10).The bolt (B) is placed at a certain distance (Z) from the bottom edge of the drawer (C). This distance (Z) is multiple of the height (m) of each monobloc element (10).
