Description

L'invention concerne un dispositif d'équilibrage et de mise en sécurité du couvercle d'un meuble de classement vertical de plans, le couvercle étant relié à l'ossa­ture du meuble au moyen d'articulations, comprenant un compas fixé par une de ses extrémités sur un tourillon solidaire du couvercle, l'autre extrémité étant libre, et tiré vers la partie supérieure du meuble par au moins un ressort, compensateur du poids du couvercle, ayant un point d'ancrage sur ladite partie supérieure et l'autre point d'ancrage sur l'extrémité libre du compas, un galet tournant librement sur une goupille solidaire de l'ossature assurant le guidage du compas et l'immobilisation du couvercle dans sa position ouverte et fermée.The invention relates to a device for balancing and securing the cover of a cabinet for vertical classification of planes, the cover being connected to the frame of the cabinet by means of joints, comprising a compass fixed by one of its ends on a pin secured to the cover, the other end being free, and drawn towards the upper part of the cabinet by at least one spring, compensating for the weight of the cover, having an anchor point on said upper part and the other point anchoring on the free end of the compass, a roller rotating freely on a pin secured to the frame ensuring the guidance of the compass and the immobilization of the cover in its open and closed position.

La plupart des meubles connus comportent un couvercle, constitué en général d'un panneau d'une seule pièce monté sur charnières ou sur pivots.Most of the known furniture comprises a cover, generally consisting of a single-piece panel mounted on hinges or on pivots.

L'ouverture de ce couvercle, qui doit permettre la mise en place des plans les plus larges couramment utilisés, s'effectue manuellement, mais le poids du couvercle se trouve parfois compensé par un système à ressort.The opening of this cover, which must allow the establishment of the widest planes commonly used, is done manually, but the weight of the cover is sometimes compensated for by a spring system.

Un dispositif assure le maintien du couvercle en posi­tion ouverte.A device maintains the cover in the open position.

En cas de fermeture accidentelle, les ressorts de com­pensation n'évitent pas à l'opérateur de se faire pincer les doigts.In the event of accidental closing, the compensating springs do not prevent the operator from being pinched.

Pour empêcher cet accident, il faut concevoir un couvercle surcompensé, qui en cas de chute, s'arrête avant la fermeture complète.To prevent this accident, a overcompensated cover, which in the event of a fall stops before complete closure.

L'inconvénient d'un tel dispositif est que le couvercle serait toujours à demi-ouvert et par conséquent nécessi­terait une manoeuvre supplémentaire pour maintenir ledit couvercle fermé par un verrou ou une serrure.The disadvantage of such a device is that the cover would always be half-open and therefore would require an additional operation to keep said cover closed by a bolt or a lock.

La présente invention a pour objet l'équipement des couvercles de meubles de classement avec un dispositif ayant quatre fonctions concomitantes :
- une surcompensation, par ressorts, du poids du couvercle,
- le maintien en position ouverte,
- l'arrêt du couvercle à quelques centimètres de la fermeture complète en cas de chute accidentelle,
- le maitien en position fermée évitant, dans l'emploi courant, le recours constant à la serrure de ver­rouillage.The subject of the present invention is the equipment of lids for filing cabinets with a device having four concomitant functions:
- overcompensation, by springs, of the weight of the cover,
- keeping in the open position,
- the cover stops a few centimeters from the complete closure in the event of an accidental fall,
- the operator in the closed position avoiding, in current use, the constant use of the locking lock.

A cette fin, le dispositif selon l'invention est carac­térisée par le fait que le compas comporte au moins une première encoche dans laquelle pénètre le galet tour­nant pour maintenir le couvercle dans sa position d'ouverture et une deuxième encoche dans laquelle pénètre le galet tournant pour maintenir le couvercle dans sa position de fermeture, et par le fait que des moyens de réglage de la tension du ressort compensateur permettent de déterminer une position de sécurité (α) avant la fermeture complète du couvercle.To this end, the device according to the invention is characterized in that the compass comprises at least a first notch in which the rotating roller enters to keep the cover in its open position and a second notch in which the rotating roller enters. to maintain the cover in its closed position, and by the fact that means for adjusting the tension of the compensating spring make it possible to determine a safety position (α) before the cover is completely closed.

Le principal avantage apporté par un tel dispositif, réside dans la simplicité de sa construction et le fait qu'il est possible de régler à volonté la position de sécurité du couvercle (arrêt avant fermeture) sans être tributaire de l'éventuel relâchement du ressort ou d'une augmentation du poids du couvercle non prévue lors de la construction.The main advantage provided by such a device lies in the simplicity of its construction and the fact that it is possible to adjust the safety position of the cover at will (stop before closing) without being dependent on the possible loosening of the spring or an increase in the weight of the cover that was not foreseen during construction.

Le couvercle est ainsi équilibré, avec indexage en position "ouvert", avec un système de sécurité, avec indexage en position "fermé".The cover is thus balanced, with indexing in the "open" position, with a security system, with indexing in the "closed" position.

La forme particulière des articulations définie dans la revendication 2 permet l'ouverture du couvercle sans qu'en aucune position du couvercle aussi bien le cou­vercle que les articulations ne débordent sur la face arrière du meuble rendant ainsi possible la fixation du meuble contre une paroi ou la fixation des meubles dos à dos.The particular shape of the articulations defined in claim 2 allows the opening of the cover without in any position of the cover both the cover and the articulations protrude on the rear face of the piece of furniture thus making it possible to fix the piece of furniture against a wall or fixing furniture back to back.

D'autres avantages ressortiront de la description d'une forme d'exécution préférentielle faite à titre d'exem­ple non limitatif et du dessin dans lequel

  • - la figure 1 est une vue de côté d'un meuble de clas­sement de plans suspendus;
  • - la figure 2 est un schéma du dispositif en position de sécurité;
  • - la figure 3 est un schéma du dispositif en position "couvercle ouvert";
  • - la figure 4 est un schéma du dispositif en position "couvercle fermé";
Other advantages will emerge from the description of a preferred embodiment given by way of nonlimiting example and from the drawing in which
  • - Figure 1 is a side view of a hanging filing cabinet;
  • - Figure 2 is a diagram of the device in the safety position;
  • - Figure 3 is a diagram of the device in the "open cover"position;
  • - Figure 4 is a diagram of the device in the "closed lid"position;

La figure 1 représente une vue de côté d'un meuble de classement de plans suspendus composé essentiellement d'un couvercle 1 qui s'ouvre et se rabat sur une ossa­ture 2.FIG. 1 represents a side view of a filing cabinet for hanging planes essentially composed of a cover 1 which opens and folds down on a frame 2.

La figure 2 représente le dispositif selon l'invention placé sur au moins un des côtés du couvercle qui est relié à l'ossature 2 par deux articulations 3, de forme trapezoïdale.FIG. 2 represents the device according to the invention placed on at least one of the sides of the cover which is connected to the framework 2 by two articulations 3, of trapezoidal shape.

Ces articulations 3 sont fixées d'un côté par boulon­nage ou soudure en un point 30 sur l'ossature 2, de l'autre côté par un pivot 31 sur le couvercle 1. Leur forme trapézoïdale permet au couvercle d'évoluer, lors de son ouverture, au-dessus du plan supérieur du meuble en dégageant totalement l'accès au classement des plans et, en position fermée, le bord extérieur du couvercle est en parfait alignement avec le bord correspondant de l'ossature, sans aspérité ni charnière extérieure, ce qui permet d'appuyer le meuble contre une paroi verticale.These joints 3 are fixed on one side by bolting or welding at a point 30 on the frame 2, on the other side by a pivot 31 on the cover 1. Their trapezoidal shape allows the cover to evolve, during its opening, above the upper plane of the cabinet, completely freeing access to the classification of the plans and, in the closed position, the outer edge of the cover is in perfect alignment with the corresponding edge of the frame, without roughness or external hinge, which allows the furniture to be pressed against a vertical wall.

Le dispositif d'équilibrage et de mise en sécurité du couvercle 1 est constitué comme suit :
- un compas 4 est fixé par une de ses extrémités 40 sur un tourillon 5, solidaire du couvercle 1, son autre extrémité 41 étant libre;
- un ressort 6, compensateur du poids du couvercle 1, est tendu entre un point d'ancrage 60 sur la partie supérieure de l'ossature 2 dans l'angle supportant l'articulation 3 du couvercle et un point d'ancrage 61 sur l'extrémité libre 41 du compas 4.The balancing and securing device for the cover 1 is constituted as follows:
- A compass 4 is fixed by one of its ends 40 to a pin 5, integral with the cover 1, its other end 41 being free;
- A spring 6, compensating for the weight of the cover 1, is stretched between an anchor point 60 on the upper part of the frame 2 in the angle supporting the articulation 3 of the cover and an anchor point 61 on the free end 41 of the compass 4.

La traction exercée par le ressort 6 sur l'extrémité libre 41 du compas 4 concourt à l'ouverture du couver­cle ainsi qu'au maintien en appui du compas 4 sur un galet de guidage 7 tournant librement sur une goupille 8, solidaire de l'ossature 2.The traction exerted by the spring 6 on the free end 41 of the compass 4 contributes to the opening of the cover as well as to the support of the compass 4 on a guide roller 7 rotating freely on a pin 8, integral with the frame 2.

Une encoche 9 ouverte sur le chant 42 du compas orienté vers le ressort 6 maintient le couvercle en position d'ouverture. La position de cette encoche définit l'ouverture angulaire du couvercle (figure 3).A notch 9 open on the edge 42 of the compass oriented towards the spring 6 keeps the cover in the open position. The position of this notch defines the angular opening of the cover (Figure 3).

Une deuxième encoche 10 ouverte sur le même chant 42 du compas 4, plus rapprochée de son point de pivotement sur le tourillon 5, maintient le couvercle en position de fermeture (figure 4).A second notch 10 open on the same edge 42 of the compass 4, closer to its pivot point on the pin 5, keeps the cover in the closed position (Figure 4).

Le réglage de la surcompensation du poids du couvercle 1 est assuré par une vis 11 permettant de faire varier la tension du ressort à partir de son point d'ancrage 61 sur l'extrémité libre 41 du compas 4. Ce réglage permet de déterminer avec précision l'angle de sécu­rité α devant rester ouvert en cas de chute brutale du couvercle 1.The adjustment of the overcompensation of the weight of the cover 1 is ensured by a screw 11 making it possible to vary the tension of the spring from its anchoring point 61 on the free end 41 of the compass 4. This adjustment makes it possible to determine with precision the safety angle α must remain open in the event of a sudden fall of the cover 1.

Le couvercle restant entr'ouvert à cause de la surcom­pensation, une pression supplémentaire de l'opérateur fait entrer le galet 7 dans l'encoche 10 : la position "couvercle fermé" est ainsi obtenue sans un recours constant à l'action d'une serrure dont la fonction est alors limitée au verrouillage du couvercle au moyen d'une clef.The cover remaining ajar due to overcompensation, an additional pressure from the operator causes the roller 7 to enter the notch 10: the position "cover closed" is thus obtained without constant recourse to the action of a lock whose function is then limited to locking the cover by means of a key.
