Description

La présente invention a pour objet une serrure du type genouillère pour la liaison entre eux d'un courvercle et d'une boîte, l'élément d'accrochage de la genouillère coopérant à cette fin avec une structure réceptrice correspondante, la genouillère étant montée sur une platine solidaire du couvercle ou de la boite, la structure réceptrice étant montée sur l'autre élément. The present invention relates to a toggle type lock for the connection between them of a cover and a box, the attachment element of the toggle cooperating for this purpose with a corresponding receiving structure, the toggle being mounted on a plate secured to the cover or the box, the receiving structure being mounted on the other element.

Des serrures de ce type existent de longue date. Locks of this type have been around for a long time.

Elles sont cependant d'un emploi fastidieux et peu pratique pour les utilisateurs, leur commande devant se faire souvent à force avec des mouvements peu explicites pour l'utilisateur non averti. However, they are tedious and inconvenient for users, their control often having to be done by force with imprecise movements for the uninformed user.

L'invention a pour objet de proposer une serrure de ce type qui soit fiable, d'un usage simple et qui puisse en outre être verrouillée aisément, avec le cas échéant indication visuelle du verrouillage. The object of the invention is to provide a lock of this type which is reliable, of simple use and which can also be easily locked, with visual indication of the locking if necessary.

Conformément à l'invention, ce résultat est obtenu avec une serrure du type genouillère pour la liaison entre eux d'un couvercle et d'une boite, l'élément d'accrochage de la genouillère coopérant à cette fin avec une structure réceptrice correspondante, la genouillère étant montée sur une platine solidaire du couvercle ou de la boite, la structure réceptrice étant montée sur l'autre élément, caractérisé en ce que la genouillère est libérée ou bloquée sur la platine support par une gachette à déplacement parallèle au plan principal de la serrure, ladite gachette coopérant à cette fin avec un organe de verrouillage solidaire de la platine dans lequel elle est maintenue en prise en position fermée par des ressorts. In accordance with the invention, this result is obtained with a lock of the toggle type for the connection between them of a cover and of a box, the attachment element of the toggle cooperating for this purpose with a corresponding receiving structure, the toggle being mounted on a plate integral with the cover or the box, the receiving structure being mounted on the other element, characterized in that the toggle is released or blocked on the support plate by a trigger moving parallel to the main plane of the lock, said trigger cooperating for this purpose with a locking member secured to the plate in which it is held in engagement in the closed position by springs.

De manière avantageuse, le déverrouillage pourra être interdit par deux systèmes, éventuellenent combinés - curseur disposé sur la genouillère et empéchant le déplacement de la gachette par venue en buté de celle-ci, avec visua'isation extérieure du verrouillage, - bar-illet à clef, la rotation du barillet assurant de manière classique le blocage de l'élément mobile, en l occurrence la gachette. Advantageously, the unlocking can be prohibited by two systems, possibly combined - slider arranged on the toggle and preventing the movement of the trigger by coming into abutment thereof, with external visualization of the locking, - bar-eyelet to key, the rotation of the barrel conventionally ensuring the locking of the movable element, in this case the trigger.

On comprendra mieux l r invention à l'-ide de la description faite ci-après d'un mode de mise en oeuvre donné à titre d'exemple non
imitatif, en référence aux dessins annexés dans isquels - a figure 1 est une vue s hématique en élévation latérale illustrant les F-itions successives de 1 gachette entre ltouver~are et la fermeture - la figure 2 est une vue éclatée d'une serrure conforme à l'invention.The invention will be better understood from the description given below of an embodiment given by way of example.
imitative, with reference to the accompanying drawings in isquels - a Figure 1 is a thematic view in side elevation illustrating the successive F-itions of 1 trigger between ltouver ~ are and the closure - Figure 2 is an exploded view of a conforming lock to the invention.

On se réfère à la figure 5. We refer to figure 5.

La serrure généralement référencée (1) a pour fonction de solidariser entre eux un couvercle t2) et une boite (3). Il s'agira préférentiellement d'une valise, ceci non limitativement. The generally referenced lock (1) has the function of joining together a cover t2) and a box (3). It will preferably be a suitcase, this without limitation.

L'un des éléments, ici la boite (3), comporte une structure réceptrice (4) rapportée ou venue de matière, dans laquelle vient en prise le bec (5) de la genouillère (6). One of the elements, here the box (3), comprises a receiving structure (4) attached or coming from material, in which engages the spout (5) of the toggle joint (6).

La genouillère (6) est articulée par des bras (7,7') sur la platine (8) solidaire du couvercle, la genouillère étant rappelée en position dégagée de la platine par des ressorts prenant appui d'une part sur la platine et d'autre part sur la genouillère. The toggle joint (6) is articulated by arms (7,7 ') on the plate (8) secured to the cover, the toggle switch being returned to the disengaged position from the plate by springs bearing on the one hand on the plate and d on the other hand on the knee pad.

On comprendra à la figure 1 par les positions 1, 2 et 3 successives représentées que la genouillère assure le verrouillage par basculement vers l'arrière autour des bras t7,7'). It will be understood in Figure 1 by the successive positions 1, 2 and 3 shown that the toggle locks by tilting backwards around the arms t7,7 ').

La genouillère, pour être bloquée en position, comporte une gachette (9) qui sera décrite plus en détails en référence à la figure 2. The toggle, to be locked in position, includes a trigger (9) which will be described in more detail with reference to FIG. 2.

La gachette est solidaire à coulissement de la genouillère, avec un léger jeu permettant son actionnement pour l'utilisateur. The trigger is secured to the sliding of the toggle joint, with a slight clearance allowing its actuation for the user.

La gachette comporte à l'intérieur un ou plusieurs ergots (10,11) qui en position de verrouillage viennent en prise dans un évidement (12) correspondant de la platine. The trigger has inside one or more lugs (10,11) which in the locked position engage in a recess (12) corresponding to the plate.

Le dégagement en est effectué par appui sur la gachette (9) qui coulisse à l'encontre de ressorts de rappel (13) prenant appui sur des tétons de la genouillère. The release is effected by pressing the trigger (9) which slides against return springs (13) bearing on pins of the toggle joint.

L'appui sur la gachette dégage les ergots des évidements correspondants. Sous l'effet des ressorts de dégagement cités plus haut, la genouillère s'écarte alors de la platine et est libérée de la structure réceptrice (5). Pressing the trigger releases the pins from the corresponding recesses. Under the effect of the release springs mentioned above, the toggle then moves away from the plate and is released from the receiving structure (5).

Selon une caratéristique importante, la gachette pourra être verrouillée par deux structures seules ou en combinaison - barillet t14) avec pêne rotatif venant empécher le deplacement de la guette par blocage de sa course au niveau d'un évidement t15), - curseur t16) déplaçable transversalement par r-pport au corps de la ge-.ouillère et comportant r curseur t17) qui est ans l'alignement d'une rainure (18) de la gachette en position d'ouvèrture, et vient contre le chant frontal (19) de celle-ci en position de blocage. According to an important characteristic, the trigger can be locked by two structures alone or in combination - barrel t14) with rotary bolt preventing the displacement of the watch by blocking its travel at a recess t15), - slider t16) movable transversely by r-pport to the body of the ge-.ouillère and comprising r cursor t17) which is in the alignment of a groove (18) of the trigger in the open position, and comes against the front edge (19) of the latter in the locked position.

Le curseur pourra masquer le barillet, par exemple de couleur verte, en position de blocage, et faire apparaître alors une indication colorée, rouge par exemple, indiquant le verrouillage. The cursor can hide the barrel, for example of green color, in blocking position, and then make appear a colored indication, red for example, indicating the locking.
