Abstract

The half turn bolt lock comprises an operating button with the bolt (4) sliding mounted and guided in a casing (1) against a spring (12) which tends to hold it in the closed position. A kinematic connection (15,21) is interposed between the bolt and the button so that the operation of the button causes withdrawal of the bolt to place it in the open position. A sector (31) rotating against a return spring (32) and sliding on its spindle has a series of cams (41-44) which engage the heel (27) of the button. The cams are arranged so that the button only controls opening of the lock after it has been activated according to a certain number of rotational movements.

Description

La présente invention vise une serrure.The present invention relates to a lock.

L'invention se rapporte, plus particulièrement aux serrures dites "pêne demi-tour", c'est-à-dire, des serrures comprenant un bouton qui commande l'effacement du pêne afin de dégager celui-ci de la gâche pour permettre l'ouverture, le pêne revenant dans sa position initiale dès que relâché.The invention relates, more particularly with locks called "latch bolt", that is to say, locks including a button which controls the erasure of the bolt in order to release it from the striker to allow opening, the bolt returning to its initial position as soon as released.

Avec ce type de serrure, il suffit de tourner le bouton pour commander l'ouverture. Pour éviter que la porte, le coffre ou autre, que la serrure permet de fermer ne puisse être ouvert que par les personnes autorisées, on adjoint généralement un mécanisme à clé, ce qui oblige l'utilisateur à posséder en permanence la clé correspondante ce qui est peu pratique.With this type of lock, just turn the button to control the opening. To prevent the door, the trunk or other, that the lock allows close can only be opened by authorized persons, we usually add a key mechanism, which forces the user to have the corresponding key at all times which is impractical.

L'un des buts de la présente invention est de réaliser une serrure à pêne demi-tour commandée par un bouton qui évite l'utilisation d'un mécanisme à clé et qui ne peut néanmoins être ouverte que par les personnes autorisées.One of the aims of the present invention is to make a latch lock controlled by a button which avoids the use of a key mechanism and which can only be opened by people allowed.

La serrure, selon l'invention, est du type comprenant un bouton de manoeuvre, un pêne demi-tour monté coulissant et guidé dans un boítier contre l'action de moyens élastiques tendant à le maintenir dans une position correspondant à la fermeture de la serrure et une liaison cinématique interposée entre ledit pêne et le bouton afin que la manoeuvre de celui-ci engendre l'effacement du pêne pour le placer dans la position d'ouverture de la serrure, des moyens étant interposés entre le bouton et la liaison cinématique afin que la serrure ne puisse être ouverte qu'après que le bouton ait été manoeuvré dans plusieurs sens correspondant à une combinaison présélectionnée, ladite serrure étant caractérisée en ce qu'elle comporte un secteur monté tournant sur un axe du boítier contre l'action de moyens de rappel et solidaire du bouton, ledit secteur étant monté coulissant sur son axe contre l'action de moyens élastiques et comportant une série de cames avec lesquelles coopère un talon d'un poussoir relié, par une liaison cinématique, au pêne, les cames étant disposées de manière que le poussoir ne commande l'ouverture de la serrure qu'après que le bouton ait été actionné suivant un certain nombre de mouvements tournants, tirants ou poussants correspondant aux cames et pris isolément ou en combinaison.The lock according to the invention is of the type comprising an operating button, a mounted latch bolt sliding and guided in a case against the action of elastic means tending to keep it in a position corresponding to the closing of the lock and a link kinematics interposed between said bolt and the button so that the maneuver of it generates the erasure of the bolt to place it in the open position of the lock, means being interposed between the button and the kinematic connection so that the lock cannot be open only after the button has been operated in several meanings corresponding to a preselected combination, said lock being characterized in that it comprises a sector mounted rotating on an axis of the housing against the action of return means and integral with the button, said sector being mounted sliding on its axis against the action elastic means and comprising a series of cams with which a heel of a connected pusher cooperates, by a kinematic connection, to the bolt, the cams being arranged so that the pusher does not control opening lock only after the button has been pressed following a number of turning, pulling movements or pushers corresponding to the cams and taken in isolation or in combination.

Grâce à cette disposition, la serrure ne peut être ouverte qu'après que le bouton ait été manoeuvré, suivant une combinaison prévue à l'avance.Thanks to this arrangement, the lock cannot be open only after the button has been operated, according to a combination provided in advance.

Suivant un détail constructif, le secteur comporte une rainure pour ramener le talon dans la position initiale de fermeture de la serrure.According to a constructive detail, the sector has a groove to return the heel to the position initial closing of the lock.

La serrure peut, suivant une variante de réalisation, comporter des moyens pour ramener automatiquement le pêne dans la position de fermeture après que celui-ci ait été effacé lorsque le bouton a été manoeuvré dans les différents sens correspondant à la combinaison.The lock can, according to an alternative embodiment, include means for automatically bringing back the bolt in the closed position after it was cleared when the button was operated in the different meanings corresponding to the combination.

Enfin, suivant une dernière caractéristique, la came du secteur correspondant à l'ouverture de la serrure est terminée par une butée avec interposition d'un ressort, ladite came présentant une partie inclinée débouchant dans la rainure. Finally, according to a last characteristic, the sector cam corresponding to the opening of the lock is terminated by a stop with interposition of a spring, said cam having an inclined opening part in the groove.

L'invention va maintenant être décrite avec plus de détails en se référant à des modes de réalisation particuliers donnés à titre d'exemple seulement et représentés aux dessins annexés, dans lesquels :The invention will now be described with more details with reference to embodiments individuals given by way of example only and shown to the accompanying drawings, in which:

Figure 11 montre en coupe la serrure en position ouverte. Figure 11 shows in section the lock in the open position.

Figure 12 est une vue en plan du secteur dans une variante de réalisation.Figure 12 is a plan view of the sector in an alternative embodiment.

La serrure représentée aux figures 1 à 11 comprend un boítier 1 avec une tétière 2 percée d'une ouverture 3 dans laquelle est mobile un pêne demi-tour 4 solidaire d'une platine 5 coulissante dans un guide 6 et terminée par un coude 7. La platine 5 est percée d'une lumière 10 dans laquelle est logé un ressort 11 de compression dont une extrémité coopère avec un téton 12 de la lumière 10 et l'autre extrémité avec le guide 6.The lock shown in Figures 1 to 11 includes a housing 1 with a headrest 2 pierced with a opening 3 in which a latch bolt is movable 4 secured to a plate 5 sliding in a guide 6 and terminated by an elbow 7. The plate 5 is pierced a light 10 in which is housed a spring 11 compression, one end of which cooperates with a nipple 12 of light 10 and the other end with the guide 6.

Dans le boítier 1 est articulé, sur un axe 14, un basculeur 15 présentant trois doigts 16, 17 et 18, le doigt 16 étant coopérant avec le coude 7, le doigt 17 recevant l'une des extrémités d'un ressort de compression dont l'autre extrémité est fixée sur une patte 19, une butée 20 étant prévue dans le boítier pour limiter le pivotement du basculeur 15.In the housing 1 is articulated, on an axis 14, a rocker 15 having three fingers 16, 17 and 18, the finger 16 being cooperating with the elbow 7, the finger 17 receiving one end of a compression spring the other end of which is fixed to a lug 19, a stop 20 being provided in the housing to limit the pivoting of the rocker 15.

Le doigt 18 est destiné à coopérer avec un poussoir 21.The finger 18 is intended to cooperate with a pusher 21.

Le poussoir 21 est monté coulissant dans des guides 22 et 23 contre l'action d'un ressort de rappel 24 inséré entre le guide 22 et un arrêtoir 25 prévu sur ledit poussoir dont l'extrémité, opposée à celle coopérant avec le doigt 18, est terminée par un talon 27.The plunger 21 is slidably mounted in guides 22 and 23 against the action of a return spring 24 inserted between the guide 22 and a stop 25 provided on said pusher whose end, opposite to that cooperating with the finger 18, is terminated by a heel 27.

Un bouton 30 est solidaire d'un secteur 31, qui peut pivoter contre l'action d'un ressort 32 sur un axe 33. Le secteur, dans la position normale de repos, porte contre la butée 34 prévue dans le boítier 1.A button 30 is integral with a sector 31, which can pivot against the action of a spring 32 on a axis 33. The sector, in the normal rest position, door against the stop 34 provided in the housing 1.

Sur l'axe 33 est monté un ressort de compression 36 qui est disposé dans un logement 37 du secteur 31 et qui, par une extrémité, coopère avec une portée 38 du secteur et, par l'autre extrémité, porte contre une tête 39 de l'axe 33. Ainsi, le secteur 31 tend à être appliqué contre une paroi la du boítier 1 et peut, moyennant une traction effectuée sur le bouton 30 contre l'action dit ressort 36, être approché de la paroi 1b dudit boítier.On the axis 33 is mounted a compression spring 36 which is arranged in a housing 37 of sector 31 and which, by one end, cooperates with a bearing 38 of the sector and, by the other end, carries against a head 39 of axis 33. Thus, sector 31 tends to be applied against a wall of the housing 1 and can, with a pull on button 30 against said action spring 36, be approached from the wall 1b of said housing.

Le secteur 31 comporte une échancrure qui est délimitée par les joues 31a et 31b dudit secteur et dans laquelle sont conformées des cames 41, 42, 43, 44 et une rainure centrale 45 reliée à la came 41 par une partie coudée 46.Sector 31 has a notch which is delimited by the cheeks 31a and 31b of said sector and in which cams 41, 42, 43, 44 are formed and a central groove 45 connected to the cam 41 by a bent part 46.

La came 44 est terminée par une butée 48 et, au voisinage de celle-ci, il est prévu un rebord 50 du côté de la rainure 45.The cam 44 is terminated by a stop 48 and, in the vicinity thereof, there is provided a flange 50 of the side of groove 45.

La came 41 (voir figures 2 et 10) présente une partie qui s'étend en pente douce depuis la joue 31a vers la joue 31b.Cam 41 (see Figures 2 and 10) has a portion which slopes gently from the cheek 31a towards the cheek 31b.

La came 42 est en forme d'arc de cercle ayant pour centre l'axe 33.The cam 42 is in the shape of an arc of a circle having for center axis 33.

La came 43 s'étend en pente douce depuis la joue 31b vers la joue 31a, tandis que la came 44 décrit un arc croissant depuis la came 43 vers la butée 48.The cam 43 extends in a gentle slope from the cheek 31b towards cheek 31a, while cam 44 describes an increasing arc from the cam 43 towards the stop 48.

Le fonctionnement est le suivant :The operation is as follows:

La serrure étant fermée, elle occupe la position des figures 1 et 2 ; le secteur portant sur la butée 34. Si on veut procéder à l'ouverture, on tire sur le bouton 30 contre l'action du ressort 36 afin d'amener le secteur 31 contre la paroi 1b, le talon 27 gravissant la came 41, puis on fait pivoter le bouton dans le sens de la flèche f (voir figures 4 et 6) pour amener le talon 27 jusqu'à la came 43. On repousse ensuite le bouton 30 afin que le talon 27 gravisse la came 43 et on fait pivoter le bouton 30 dans le sens de la flèche g (voir figures 8 et 9). Ainsi, le poussoir 21 est déplacé de manière que, le doigt 18 étant poussé, le doigt 16 commande l'ouverture du pêne 4 (voir figure 11).The lock being closed, it occupies the position Figures 1 and 2; the sector bearing on the stop 34. If we want to open, we pull on the button 30 against the action of the spring 36 in order to bring the sector 31 against the wall 1b, the heel 27 climbing the cam 41, then rotate the button in the direction of arrow f (see Figures 4 and 6) to bring the heel 27 to cam 43. Then push button 30 so the heel 27 climbs the cam 43 and we rotate the button 30 in the direction of the arrow g (see figures 8 and 9). Thus, the pusher 21 is moved so that, with the finger 18 being pushed, the finger 16 controls the opening bolt 4 (see Figure 11).

Pour ramener le pêne dans la position de fermeture, il faut refaire pivoter le secteur 31 dans le sens de la flèche f afin de dégager le talon 27 de la butée 48 et du rebord 50 puis tirer sur le bouton 30 afin que le talon 27 tombe dans la rainure 45, le ressort 32 ramenant le secteur dans la position initiale.To return the bolt to the closed position, you have to rotate sector 31 in the direction of the arrow f in order to release the heel 27 from the stop 48 and edge 50 then pull on button 30 so that the heel 27 falls into the groove 45, the spring 32 bringing back the sector in the initial position.

A la figure 12, on a représenté une variante de réalisation dans laquelle, lorsque la serrure a été ouverte et lorsqu'on relâche le bouton, la serrure revient dans sa position initiale automatiquement. A cet effet, le secteur, à l'extrémité de sa came 44a, comporte un ressort 52 et la came 44a est inclinée en direction de la rainure 45a. Ainsi, lorsque la serrure a été ouverte, le talon 27 coopèrant avec le ressort 52, celui-ci tend à repousser ledit talon qui, du fait de l'inclinaison de la came 44a, tombe dans la rainure 45a, le ressort 32 ramenant le secteur dans sa position initiale.In FIG. 12, a variant has been represented. in which, when the lock has been open and when the button is released, the lock returns in its initial position automatically. To this end, the sector, at the end of its cam 44a, has a spring 52 and the cam 44a is inclined in the direction of the groove 45a. So when the lock was opened, the heel 27 cooperating with the spring 52, the latter tends to repel said heel which, due to the inclination from cam 44a, falls into groove 45a, the spring 32 returning the sector to its initial position.

Il est évident, que si on relâche le bouton à un moment quelconque de la manoeuvre, la serrure revient automatiquement dans sa position initiale.Obviously, if you release the button at any time during the maneuver, the lock returns automatically in its initial position.

La position des cames pourrait, par exemple, être différente. On pourrait également prévoir un simple système pour commander directement l'ouverture de la serrure à partir du secteur et annihiler le mécanisme de sécurité, selon l'invention, par exemple en prévoyant une biellette pouvant sélectivement être insérée entre le secteur 31 et le doigt 18. The position of the cams could, for example, be different. We could also provide a simple system to directly control the opening of the lock from the sector and annihilate the security mechanism, according to the invention, for example by providing a link can be selectively inserted between sector 31 and finger 18.

Bien entendu, l'invention n'est pas limitée aux modes de réalisation qui viennent d'être décrits et représentés. On pourra y apporter de nombreuses modifications de détails sans sortir pour cela du cadre de l'invention.Of course, the invention is not limited to the embodiments which have just been described and represented. We can make many modifications details without departing from the scope of the invention.

Ainsi, on peut prévoir une liaison reliant le secteur 31 au basculeur 15 et permettant d'actionner directement la serrure à partir du bouton 30. Cette liaison peut être sélectivement insérer entre ces deux éléments afin qu'ainsi, dans certains cas, la serrure fonctionne sans qu'il soit nécesaire d'effectuer les manoeuvres correspondant à la combinaison sélectionnée.Thus, one can provide a link connecting sector 31 to rocker 15 and used to activate directly the lock from button 30.
