Abstract

The lock comprises a case (101) with two parallel walls (102), a faceplate (110) perpendicular to the walls and a bolt (200) shaped to be supported on an internal face (112) of the faceplate by tipping against it. The bolt occupies one or other of two stable positions. A movable locking assembly (300,400) is acted on by a first spring (415) towards a bolt locking position. There is disabling sensor (800) which prevents the locking assembly from reaching the locking position.

No. 5,113,676 discloses a door that can open in both directions, with a complex bolt assembly with two elementary bolts superimposed and offset angularly, articulated on a sliding body in which is articulated a lever which, depending on its angular position (controlled by a key and a probe), allows or not a locking of the bolt assembly.

Plus précisément, la présente invention propose une serrure à montage universel dans laquelle le pêne ne génère pas d'effort excessif à l'ouverture de la porte. Une telle serrure, permettant ainsi une ouverture aisée de la porte sur laquelle elle est installée, est particulièrement adaptée à une porte dite d'urgence.More specifically, the present invention provides a universal mounting lock in which the bolt does not generate excessive force when opening the door. Such a lock, thus allowing easy opening of the door on which it is installed, is particularly suitable for a so-called emergency door.

La présente invention a plus particulièrement pour objet une serrure de porte telle que définie par la revendication 1.The present invention more particularly relates to a door lock as defined by claim 1.

Selon une caractéristique particulière, les moyens d'inhibition comportent un palpeur dont une première extrémité fait saillie hors de la têtière, sollicité de façon élastique par un deuxième ressort vers l'extérieur de la serrure, et apte à être déplacé vers l'intérieur de la serrure jusqu'à une position dans laquelle l'inhibition de l'ensemble de blocage est inactive.According to a particular characteristic, the inhibition means comprise a feeler whose first end protrudes out of the headrest, resiliently biased by a second spring towards the outside of the lock, and able to be moved towards the inside of the lock. the lock to a position in which the inhibition of the locking assembly is inactive.

Lorsque la porte est ouverte, le palpeur est repoussé vers l'extérieur de la serrure par le deuxième ressort mais l'ensemble de blocage mobile est inopérant sous l'action des moyens d'inhibition. Le pêne est alors libre de basculer et de se rétracter à l'intérieur de la serrure. Lorsque l'on referme la porte, le pêne est d'abord repoussé, tout en basculant, à l'intérieur du boîtier de serrure, en entrant en contact avec l'extérieur de la gâche. La porte peut donc se fermer. En même temps, le palpeur est repoussé à l'intérieur de la serrure en rendant l'ensemble de blocage actif. Le pêne est alors bloqué en saillie dans la gâche de la serrure, et la porte ne peut pas s'ouvrir.When the door is open, the probe is pushed out of the lock by the second spring but the locking assembly mobile is inoperative under the action of the inhibiting means. The bolt is then free to tilt and retract inside the lock. When closing the door, the bolt is first pushed, while tilting, inside the lock housing, coming into contact with the outside of the striker. The door can therefore close. At the same time, the probe is pushed back inside the lock by making the locking assembly active. The bolt is then blocked protruding into the latch of the lock, and the door can not open.

Selon une autre caractéristique particulière, l'ensemble de blocage mobile comporte une queue de pêne coopérant avec le pêne par une liaison de forme, la liaison de forme permettant de définir les deux positions stables prédéterminées. La queue de pêne coulisse entre les deux parois parallèles selon une direction perpendiculaire à la têtière.According to another particular feature, the movable locking assembly comprises a bolt tail cooperating with the bolt by a form connection, the form connection to define the two predetermined stable positions. The bolt tail slides between the two parallel walls in a direction perpendicular to the headrest.

Cette liaison de forme permet d'obtenir un mécanisme symétrique, tel que chacune des positions stables correspond à l'utilisation de la serrure sans main dans une configuration particulière de montage.This form connection makes it possible to obtain a symmetrical mechanism, such that each of the stable positions corresponds to the use of the hand-free lock in a particular mounting configuration.

Selon une autre caractéristique particulière, le pêne comporte :

  • une première surface d'appui dans une gâche
  • une deuxième surface d'appui dans la gâche, symétrique à la première surface d'appui par rapport à un plan de symétrie du pêne, les deux surfaces d'appui formant un premier double biseau ;
  • une première surface de butée sensiblement parallèle à la première surface d'appui, prolongeant la deuxième surface d'appui, et susceptible de prendre appui sur une première paroi précitée ;
  • un premier épaulement dans le prolongement de la première surface de butée, apte à coopérer avec une extrémité de la queue de pêne ;
  • une deuxième surface de butée sensiblement parallèle à la deuxième surface d'appui, prolongeant la première surface d'appui, et susceptible de prendre appui sur une deuxième paroi précitée ;
  • un deuxième épaulement dans le prolongement de la deuxième surface de butée, le deuxième épaulement étant symétrique au premier épaulement par rapport au plan de symétrie, et apte à coopérer avec l'extrémité de la queue de pêne ; et
  • une came profilée, prolongeant les deux épaulements, symétrique par rapport au plan de symétrie, et coopérant avec deux rampes de ladite queue de pêne.
According to another particular characteristic, the bolt comprises:
  • a first support surface in a strike
  • a second bearing surface in the striker, symmetrical to the first bearing surface with respect to a plane of symmetry of the bolt, the two bearing surfaces forming a first double bevel;
  • a first abutment surface substantially parallel to the first bearing surface, extending the second bearing surface, and capable of bearing on a first aforementioned wall;
  • a first shoulder in the extension of the first abutment surface, adapted to cooperate with one end of the bolt tail;
  • a second abutment surface substantially parallel to the second bearing surface, extending the first bearing surface, and capable of bearing on a second aforementioned wall;
  • a second shoulder in the extension of the second abutment surface, the second shoulder being symmetrical to the first shoulder relative to the plane of symmetry, and adapted to cooperate with the end of the bolt tail; and
  • a profiled cam, extending the two shoulders, symmetrical with respect to the plane of symmetry, and cooperating with two ramps of said bolt tail.

Les deux surfaces d'appui en double biseau du pêne permettent ainsi une fermeture facile de la porte par une simple action de poussée ou de traction. De plus, les surfaces de butée sensiblement parallèles aux surfaces d'appui et adaptées à prendre appui sur les parois du boîtier de la serrure, permettent avantageusement de minimiser l'effort sur le mécanisme de blocage. Les deux épaulements permettent aussi d'assurer un bon contact avec l'extrémité de la queue de pêne, ce qui assure un jeu minimum à la position de blocage. Enfin, la came profilée permet, lors de l'ouverture et de la fermeture de la porte, de faire coulisser la queue de pêne entre les deux parois du boîtier. Le pêne peut donc basculer au contact de la gâche, et se rétracter à l'intérieur du boîtier de serrure.The two double bevel bearing surfaces of the bolt thus allow easy closing of the door by a simple pushing or pulling action. In addition, abutment surfaces substantially parallel to the bearing surfaces and adapted to bear against the walls of the lock housing, advantageously allow to minimize the force on the locking mechanism. The two shoulders also ensure good contact with the end of the bolt tail, which ensures a minimum clearance to the locking position. Finally, the profiled cam allows, during the opening and closing of the door, to slide the bolt tail between the two walls of the housing. The bolt can tilt in contact with the striker, and retract inside the lock housing.

Selon une autre caractéristique particulière, la serrure comporte une biellette, la biellette étant d'une part liée en rotation par un premier axe à un premier élément choisi parmi le pêne et la queue de pêne, et, d'autre part liée, au second élément choisi parmi le pêne et la queue de pêne, par un agencement constitué d'un deuxième axe et d'une découpe allongée. La largeur de la biellette correspond à l'écartement desdites deux parois parallèles.According to another particular feature, the lock comprises a link, the rod being firstly rotatably connected by a first axis to a first element selected from the bolt and the bolt tail, and secondly linked, to the second element chosen from the bolt and the bolt tail, by an arrangement consisting of a second axis and an elongated cutout. The width of the rod corresponds to the spacing of said two parallel walls.

Ce mécanisme de biellette permet avantageusement de réduire la largeur de l'évidement prévu dans la têtière pour le passage du pêne basculant.This link mechanism advantageously reduces the width of the recess provided in the headrest for the passage of the rocker bolt.

Selon une autre caractéristique particulière, l'ensemble de blocage mobile comporte un élément de blocage basculant autour d'un axe de rotation perpendiculaire aux dites parois parallèles.According to another particular feature, the movable locking assembly comprises a blocking element pivoting about an axis of rotation perpendicular to said parallel walls.

Cet élément de blocage basculant et la queue de pêne constituent ledit ensemble de blocage mobile du pêne.This rocking blocking element and the bolt tail constitute said movable locking assembly of the bolt.

Selon une autre caractéristique particulière, l'élément de blocage basculant comporte un rouleau susceptible d'exercer une poussée sur la queue de pêne, la poussée s'exerçant sur une face de ladite queue de pêne.According to another particular feature, the tilting blocking element comprises a roller capable of exerting a thrust on the bolt tail, the thrust exerted on one face of said bolt tail.

Selon une autre caractéristique particulière, la queue de pêne est guidée par deux pions adaptés à guider ladite queue de pêne perpendiculairement à la têtière.According to another particular characteristic, the bolt tail is guided by two pins adapted to guide said bolt tail perpendicularly to the headrest.

Sous l'effet de cette poussée, la queue de pêne peut, guidée par les deux pions, coulisser jusqu'à la position de blocage, lorsque ce déplacement n'est pas entravé par les moyens d'inhibition. La poussée est provoquée par un premier ressort sollicitant l'élément de blocage basculant.Under the effect of this thrust, the bolt tail can, guided by the two pins, slide to the locking position, when this movement is not impeded by the inhibiting means. The thrust is caused by a first spring biasing the tilting blocking element.

Selon une autre caractéristique particulière, la position de blocage est assurée lorsque la droite définie d'une part par le point de contact entre le rouleau et la queue de pêne, et d'autre part par la direction de déplacement de la queue de pêne, coupe sensiblement l'axe de rotation de l'élément de blocage.According to another particular characteristic, the locking position is ensured when the straight line defined on the one hand by the point of contact between the roller and the bolt tail, and on the other hand by the direction of movement of the bolt tail, substantially cuts the axis of rotation of the locking element.

Dans cette configuration en effet, le couple de la force générée par la queue de pêne sur l'élément basculant est nulle ou insuffisante pour engendrer le basculement de l'élément de blocage.In this configuration in fact, the torque of the force generated by the bolt tail on the tilting element is zero or insufficient to cause the tilting of the locking element.

Selon une autre caractéristique particulière, les moyens d'inhibition comportent un deuxième élément de blocage basculant dont une première extrémité est susceptible de s'interposer, dans une position d'inhibition, entre le pêne et la têtière.According to another particular characteristic, the inhibiting means comprise a second rocking locking element, a first end of which is capable of being interposed, in a position of inhibition, between the bolt and the headrest.

En s'interposant entre le pêne et la têtière, les moyens d'inhibition limitent le déplacement de la queue de pêne. Le rouleau de l'élément basculant ne peut donc pas se positionner de telle façon que la droite définie précédemment coupe sensiblement l'axe de rotation de l'élément de blocage. L'ensemble de blocage est ainsi inhibé.By interposing between the bolt and the headrest, the inhibiting means limit the movement of the bolt tail. The roll of the tilting element can not therefore be positioned in such a way that the straight line defined previously substantially cuts the axis of rotation of the locking element. The blocking assembly is thus inhibited.

Selon une autre caractéristique particulière, la serrure comporte quatre goupilles emmanchées à force dans deux percements du pêne, dépassant de part et d'autre dudit pêne, les deux percements étant parallèles à ladite têtière.According to another particular feature, the lock comprises four pins fitted with force in two holes of the bolt, protruding on either side of said bolt, the two openings being parallel to said headrest.

Ces goupilles prennent appui sur la face interne de la têtière et permettent le basculement du pêne contre celle-ci.These pins bear on the inner face of the headrest and allow the bolt to tilt against it.

Selon une autre caractéristique particulière, la première extrémité du deuxième élément de blocage est adaptée à s'interposer entre une goupille précitée et la têtière.According to another particular feature, the first end of the second locking member is adapted to interpose between a pin and the aforementioned headrest.

En s'interposant ainsi, l'élément de blocage limite le déplacement de la queue de pêne qui est solidaire du pêne et, comme décrit précédemment, la position de blocage ne peut être atteinte.By interposing thus, the locking element limits the movement of the bolt shank which is integral with the bolt and, as previously described, the locking position can not be reached.

Selon une autre caractéristique, la serrure comporte un troisième ressort, qui tend à ramener le deuxième élément de blocage basculant dans la position d'inhibition.According to another characteristic, the lock comprises a third spring, which tends to bring the second rocking locking element into the inhibiting position.

Corrélativement, le palpeur comporte une deuxième extrémité, adaptée à faire basculer le deuxième élément de blocage basculant, et à lui faire quitter la position d'inhibition.Correlatively, the probe comprises a second end adapted to tilt the second tilting blocking element, and to leave the inhibition position.

Lorsque la porte est ouverte, le palpeur est repoussé vers l'extérieur de la serrure par le deuxième ressort et son extrémité ne fait pas basculer le deuxième élément de blocage basculant. L'élément de blocage basculant est alors maintenu dans la position d'inhibition par le troisième ressort, et l'ensemble de blocage mobile est inactif. En revanche, lorsque la porte est fermée, l'extrémité du palpeur fait basculer le deuxième élément de blocage basculant qui quitte la position d'inhibition. L'ensemble de blocage est alors actif.When the door is open, the probe is pushed out of the lock by the second spring and its end does not rock the second tilting blocking element. The tilting blocking member is then held in the inhibit position by the third spring, and the movable blocking assembly is inactive. On the other hand, when the door is closed, the probe end tilts the second tilting blocking element that leaves the inhibition position. The blocking set is then active.

Selon une autre caractéristique particulière, la serrure comporte un levier, solidaire d'un fouillot, adapté à dégager l'élément de blocage de la position de blocage.According to another particular feature, the lock comprises a lever secured to a follower adapted to disengage the blocking element from the locking position.

Ce levier peut ainsi être actionné par une poignée de porte dont une tige est engagée dans le fouillot. La poignée de porte permet ainsi de dégager l'élément de blocage basculant de la position de blocage et de libérer le mouvement du pêne. Une pression ou une traction sur la porte entraîne alors le recul du pêne dans le boîtier de la serrure et la porte peut s'ouvrir.This lever can be actuated by a door handle with a rod is engaged in the follower. The door handle thus makes it possible to release the rocking blocking element from the blocking position and to release the movement of the bolt. Pressing or pulling on the door then causes the bolt to fall back into the lock housing and the door can open.

Selon une autre caractéristique, la première extrémité du palpeur est en forme d'un deuxième double biseau.According to another characteristic, the first end of the probe is in the form of a second double bevel.

Ainsi, lors de la fermeture de la porte, l'extrémité du palpeur en forme de deuxième double biseau rencontre l'huisserie de la porte et provoque le déplacement du palpeur à l'intérieur de la serrure, ce qui inhibe l'ensemble de blocage. Le deuxième double biseau permet avantageusement le montage de la serrure sur une porte ouvrant à droite ou à gauche.Thus, when closing the door, the end of the probe in the form of a second double bevel meets the frame of the door and causes the movement of the probe inside the lock, which inhibits the locking assembly. The second double bevel advantageously allows the mounting of the lock on a door opening to the right or left.

La figure 1 représente une vue partielle de l'intérieur d'une serrure 100. Sur cette figure, les différents éléments de la serrure 100 sont représentés dans les positions qu'ils occupent lorsque la porte est ouverte.Figure 1 shows a partial view of the interior of a lock 100. In this figure, the various elements of the lock 100 are shown in the positions they occupy when the door is open.

Cette serrure 100 comporte un boîtier 101 muni de deux parois parallèles 102 et une têtière 110 perpendiculaire aux deux parois parallèles 102. Le boîtier 101 est représenté ouvert (sans le foncet) de sorte que l'une des deux parois 102 n'est pas visible sur cette figure.This lock 100 comprises a housing 101 provided with two parallel walls 102 and a headrest 110 perpendicular to the two parallel walls 102. The housing 101 is shown open (without the feature) so that one of the two walls 102 is not visible. in this figure.

La serrure 100 comporte également un pêne 200 qui sera décrit ultérieurement en référence à la figure 2.The lock 100 also comprises a bolt 200 which will be described later with reference to FIG.

La serrure 100 comporte un ensemble de blocage mobile 300, 400 constitué d'une queue de pêne 300 et d'un élément de blocage basculant 400.The lock 100 comprises a mobile locking assembly 300, 400 consisting of a bolt tail 300 and a rocking blocking element 400.

La largeur de la queue de pêne 300 est telle que la queue de pêne 300 est adaptée à coulisser dans un mouvement de translation entre les deux parois parallèles 102 selon une direction perpendiculaire à la têtière 110. La queue de pêne 300 est guidée dans ce mouvement de translation par deux pions 302, fixés perpendiculairement aux parois 102.The width of the bolt shank 300 is such that the bolt shank 300 is adapted to slide in a translation movement between the two parallel walls 102 in a direction perpendicular to the headrest 110. The bolt shank 300 is guided in this movement. translationally by two pins 302, fixed perpendicularly to the walls 102.

L'élément de blocage basculant 400, comporte un premier axe de rotation 410 fixé perpendiculairement à une paroi 102.The tilting blocking element 400 comprises a first axis of rotation 410 fixed perpendicularly to a wall 102.

L'élément de blocage basculant 400 est sollicité élastiquement par un premier ressort 415, dont une extrémité est fixée au boîtier 101, vers une position de blocage du pêne 200. La position de blocage sera décrite ultérieurement en référence à la figure 4d.The tilting blocking element 400 is resiliently biased by a first spring 415, one end of which is fixed to the casing 101, towards a locking position of the bolt 200. The locking position will be described later with reference to FIG. 4d.

L'élément de blocage basculant 400 comporte également un rouleau 420 adapté à tourner autour d'un deuxième axe de rotation 422 perpendiculaire aux parois 102.The rocking blocking element 400 also comprises a roller 420 adapted to rotate about a second axis of rotation 422 perpendicular to the walls 102.

Le rouleau 420 est susceptible d'exercer une poussée sur une face 310 de la queue de pêne 300. Soumise à cette poussée, la queue de pêne 300 peut se déplacer en translation, guidée par les deux pions 302, tel que décrit précédemment.The roller 420 is likely to exert thrust on a face 310 of the bolt shank 300. Subject to this thrust, the bolt shank 300 can move in translation, guided by the two pins 302, as described above.

La serrure 100 comporte également un levier 500, solidaire d'un fouillot 510. Le levier 500 peut ainsi être actionné par une poignée de porte (non représentée) dont une tige est engagée dans le fouillot 510. Le levier 500 est adapté, lorsque la poignée tourne, à appuyer sur un autre rouleau 402, perpendiculaire aux parois 102, de l'élément de blocage basculant 400, et d'entraîner le basculement de l'élément de blocage basculant 400, autour de son premier axe de rotation 410, tel que décrit précédemment.The lock 100 also comprises a lever 500, integral with a follower 510. The lever 500 can thus be actuated by a door handle (not shown), a rod of which is engaged in the follower 510. The lever 500 is adapted when the handle rotates, to press another roller 402, perpendicular to the walls 102, of the tilting blocking element 400, and to cause the tilting blocking element 400 to tilt around its first axis of rotation 410, such as as previously described.

La figure 2 représente un pêne 200, une queue de pêne 300 et une biellette 600 selon l'invention.FIG. 2 shows a bolt 200, a bolt tail 300 and a link 600 according to the invention.

Le pêne 200 comporte deux surfaces d'appui 204, symétriques par rapport au plan de symétrie 202 du pêne 200, et formant un premier double biseau 206. Les surfaces d'appui 204 sont adaptées à prendre appui sur la gâche 702 de l'huisserie d'une porte 700 représentée sur la figure 4a.The bolt 200 comprises two bearing surfaces 204, symmetrical with respect to the plane of symmetry 202 of the bolt 200, and forming a first double bevel 206. The bearing surfaces 204 are adapted to bear on the striker 702 of the frame of a door 700 shown in Figure 4a.

Chacune des surfaces d'appui 204 est prolongée par une surface courbe puis par une surface de butée 208, parallèle à l'autre surface d'appui 204 et susceptible de prendre appui sur une paroi 102.Each of the bearing surfaces 204 is extended by a curved surface and then by an abutment surface 208, parallel to the other bearing surface 204 and able to bear on a wall 102.

Chaque surface de butée 208 est prolongée par un épaulement 210. Les surfaces de butée 208 et les épaulements 210 sont symétriques par rapport au plan de symétrie 202 du pêne 200.Each abutment surface 208 is extended by a shoulder 210. The abutment surfaces 208 and the shoulders 210 are symmetrical with respect to the plane of symmetry 202 of the bolt 200.

Les épaulements 210 sont prolongés par une came profilée 212, également symétrique par rapport au plan de symétrie 202 du pêne 200.The shoulders 210 are extended by a profiled cam 212, also symmetrical with respect to the plane of symmetry 202 of the bolt 200.

Le pêne 200 comporte un autre plan de symétrie 214, orthogonal au plan de symétrie 202.The bolt 200 comprises another plane of symmetry 214, orthogonal to the plane of symmetry 202.

Le pêne 200 comporte un évidement 220, de part et d'autre du plan de symétrie 214, définissant deux branches 222 du pêne 200.The bolt 200 comprises a recess 220, on either side of the plane of symmetry 214, defining two branches 222 of the bolt 200.

Les deux branches 222 du pêne 200 sont traversées par un trou 224 dont un diamètre est contenu dans le premier plan de symétrie 202.The two branches 222 of the bolt 200 are traversed by a hole 224 whose diameter is contained in the first plane of symmetry 202.

La queue de pêne 300 comporte un plan de symétrie 304, parallèle aux parois 102. Elle comporte également une extrémité arrondie 320, symétrique par rapport au plan de symétrie 304 prolongée par deux rampes 330, également symétriques par rapport au plan de symétrie 304.The bolt tail 300 has a plane of symmetry 304, parallel to the walls 102. It also has a rounded end 320, symmetrical with respect to the plane of symmetry 304 extended by two ramps 330, also symmetrical with respect to the plane of symmetry 304.

La queue de pêne 300 comporte un autre plan de symétrie 308, orthogonal par rapport au plan de symétrie 304.The bolt shank 300 comprises another plane of symmetry 308, orthogonal to the plane of symmetry 304.

La queue de pêne 300 comporte un évidement 340, de part et d'autre du plan de symétrie 308. Elle forme ainsi, autour de l'évidement 340, une pièce en forme de « U » dont la base est constituée par la face 310.The bolt shank 300 comprises a recess 340, on either side of the plane of symmetry 308. It thus forms, around the recess 340, a "U" shaped part whose base is constituted by the face 310 .

Les deux branches 314 du « U » ainsi définies sont reliées par un axe cylindrique 316, traversant perpendiculairement l'évidement 340, un diamètre de l'axe cylindrique 316 étant contenu dans le plan de symétrie 304.The two branches 314 of the "U" thus defined are connected by a cylindrical axis 316, perpendicularly crossing the recess 340, a diameter of the cylindrical axis 316 being contained in the plane of symmetry 304.

La biellette 600 comporte deux faces parallèles et deux cotés parallèles, perpendiculaires à ces deux faces, et symétriques par rapport à un plan de symétrie 604 de la biellette 600.The link 600 comprises two parallel faces and two parallel sides, perpendicular to these two faces, and symmetrical with respect to a plane of symmetry 604 of the link 600.

A proximité d'une de ses extrémités 601, la biellette 600 est traversée par un trou cylindrique 620, un diamètre de ce trou cylindrique 620 étant contenu dans le plan de symétrie 604. Le diamètre de ce trou 620 est sensiblement de la taille du trou 224 du pêne 200.Near one of its ends 601, the rod 600 is traversed by a cylindrical hole 620, a diameter of this cylindrical hole 620 being contained in the plane of symmetry 604. The diameter of this hole 620 is substantially the size of the hole 224 of the bolt 200.

La biellette 600 comporte une découpe allongée 610, symétrique par rapport au plan de symétrie 604, et débouchant sur une extrémité opposée à l'extrémité 601. Le fond de cette découpe allongée 610 est de forme circulaire, d'un diamètre sensiblement supérieur au diamètre de l'axe 316 de la queue de pêne 300.The link 600 comprises an elongate cutout 610, symmetrical with respect to the plane of symmetry 604, and opening on an end opposite to the end 601. The bottom of this elongated cutout 610 is circular in shape, with a diameter substantially greater than the diameter. of the axis 316 of the bolt tail 300.

De même, l'épaisseur de la biellette 600, définie par la distance entre les deux faces de la biellette 600, est sensiblement inférieure à la hauteur de l'évidement 340 entre les deux branches 314 de la queue de pêne 300, et à la hauteur de l'évidement 220 entre les deux branches 222 du pêne 200.Similarly, the thickness of the rod 600, defined by the distance between the two faces of the rod 600, is substantially less than the height of the recess 340 between the two branches 314 of the bolt shank 300, and at the height of the recess 220 between the two branches 222 of the bolt 200.

L'axe 316 de la queue de pêne 300 peut ainsi se déplacer en translation dans la découpe allongée 610 de la biellette 600, les plans de symétrie 604 et 304 étant alors confondus.The axis 316 of the bolt shank 300 can thus move in translation in the elongated cutout 610 of the link 600, the symmetry planes 604 and 304 then being merged.

La biellette 600 est placée dans l'évidement 220 du pêne 200, de sorte que les trous 620 et 224 soient alignés. Les trous 620 et 224 sont alors traversés par un axe cylindrique 630, adapté à maintenir la biellette 600 en rotation par rapport au pêne 200. Cet axe cylindrique 630 peut par exemple être monté serré dans le trou 224 du pêne 200 et monté coulissant dans le trou 620 de la biellette 600.The rod 600 is placed in the recess 220 of the bolt 200, so that the holes 620 and 224 are aligned. The holes 620 and 224 are then traversed by a cylindrical axis 630, adapted to keep the rod 600 in rotation relative to the bolt 200. This cylindrical axis 630 may for example be tightly mounted in the hole 224 of the bolt 200 and slidably mounted in the hole 620 of the link 600.

- L'extrémité 320 de la queue de pêne 300 est apte à glisser le long de chacun des épaulements 210 du pêne 200. De même, la came profilée 212 du pêne 200 est adaptée à glisser le long des deux rampes 330 de la queue de pêne 300. Cet agencement permet de définir une liaison de forme entre le pêne 200 et la queue de pêne 300, qui sera décrite ultérieurement en référence aux figures 4a à 4d.- The end 320 of the bolt shank 300 is able to slide along each of the shoulders 210 of the bolt 200. Similarly, the profiled cam 212 of the bolt 200 is adapted to slide along the two ramps 330 of the shank. This arrangement makes it possible to define a shape connection between the bolt 200 and the bolt shank 300, which will be described later with reference to FIGS. 4a to 4d.

Le pêne 200 est traversé par deux percements 230 parallèles à la têtière, percés symétriquement par rapport au plan de symétrie 202. Ces percements 230 sont situés entre le trou 224 et les épaulements 210.The bolt 200 is traversed by two holes 230 parallel to the headrest, drilled symmetrically with respect to the plane of symmetry 202. These holes 230 are located between the hole 224 and the shoulders 210.

Deux premières goupilles 232 sont emmanchées à force dans les percements 230 par une face supérieure du pêne 200, parallèle au plan de symétrie 214, et dépassent de cette face supérieure. De même, deux autres goupilles 232 sont emmanchées à force dans les percements 230 par une face inférieure du pêne 200, parallèle au plan de symétrie 214, et dépassent de cette face inférieure.First two pins 232 are force-fitted into the bores 230 by an upper face of the bolt 200, parallel to the plane of symmetry 214, and protrude from this upper face. Similarly, two other pins 232 are force-fitted into the bores 230 by a lower face of the bolt 200, parallel to the plane of symmetry 214, and protrude from this lower face.

Ces goupilles 232, sont adaptées à prendre appui sur une face interne 112 de la têtière 110.These pins 232, are adapted to bear on an inner face 112 of the headrest 110.

La serrure 100 comporte des moyens d'inhibition 800, 900 représentés à la figure 3. Ces moyens d'inhibition 800, 900 sont constitués, entre autres d'un palpeur 800, dont une première extrémité 810, en forme de deuxième double biseau, fait saillie hors de la têtière 110, et d'un deuxième élément de blocage basculant 900.The lock 100 comprises muting means 800, 900 shown in FIG. 3. These muting means 800, 900 are constituted, inter alia, by a feeler 800, of which a first end 810, in the form of a second double bevel, protrudes out of the headrest 110, and a second tilting blocking element 900.

Le deuxième élément de blocage basculant 900, comporte un axe de rotation 910 et une première extrémité 920 formant cale, adaptée à s'interposer, dans une position dite d'inhibition, entre une goupille 232 du pêne 200 et la têtière 110. Le deuxième élément de blocage basculant 900 est sollicité par un troisième ressort 930 qui tend à ramener le deuxième élément de blocage basculant 900 dans la position d'inhibition.The second rocking blocking element 900 comprises an axis of rotation 910 and a first wedge end 920 adapted to be interposed, in a so-called inhibition position, between a pin 232 of the bolt 200 and the headrest 110. The second rocking blocking element 900 is biased by a third spring 930 which tends to bring the second rocking blocking element 900 into the inhibition position.

Le palpeur 800 est sollicité de façon élastique par un deuxième ressort 820 vers l'extérieur de la serrure 100. Le palpeur 800 comporte un ergot 812, parallèle à la têtière 110, qui prend appui sur une face interne 112 de la têtière 110, pour limiter la saillie du palpeur 800 hors de la têtière 110, lorsque celui-ci est sollicité par le deuxième ressort 820.The probe 800 is resiliently biased by a second spring 820 towards the outside of the lock 100. The probe 800 has a lug 812, parallel to the headrest 110, which bears on an inner face 112 of the headrest 110, for limit the protrusion of the probe 800 out of the headrest 110, when it is urged by the second spring 820.

Le palpeur 800, par pression sur sa première extrémité 810, est adapté à se déplacer, malgré l'effort du deuxième ressort 820, vers l'intérieur de la serrure 100, lors de la fermeture de la porte.The probe 800, by pressing on its first end 810, is adapted to move, despite the effort of the second spring 820, towards the inside of the lock 100, when closing the door.

Dans une variante, les goupilles 232 sont remplacées par des épaulements du pêne, adaptés à prendre appui sur la face interne 112 de la têtière 100.In a variant, the pins 232 are replaced by shoulders of the bolt, adapted to bear on the inner face 112 of the headrest 100.

Lorsque le palpeur 800 se déplace vers l'intérieur de la serrure 100, sa deuxième extrémité 830, rencontre une deuxième extrémité 940 du deuxième élément de blocage basculant 900, ce qui entraîne sa rotation autour de l'axe de rotation 910, et lui fait quitter la position d'inhibition, telle que représentée figure 1.When the probe 800 moves towards the inside of the lock 100, its second end 830 meets a second end 940 of the lock 100. second rocking blocking element 900, which causes its rotation about the axis of rotation 910, and makes it leave the position of inhibition, as shown in FIG.

Nous allons maintenant décrire le fonctionnement de la serrure 100 au cours de différentes étapes correspondant à la fermeture d'une porte équipée d'une serrure 100, cette description étant faîte en référence :

  • aux figures 4a à 4d qui représentent schématiquement une serrure 100 suivant une coupe transversale IV-IV de la figure 1; et
  • aux figures 5a à 5c qui représentent schématiquement une serrure 100 suivant une coupe transversale V-V de la figure 1.
We will now describe the operation of the lock 100 during different stages corresponding to the closing of a door equipped with a lock 100, this description being made with reference:
  • Figures 4a to 4d which schematically show a lock 100 in a cross section IV-IV of Figure 1; and
  • FIGS. 5a to 5c, which schematically represent a lock 100 in cross section VV of FIG.

Les figures 4a et 5a représentent la serrure 100 lorsque la porte est ouverte.Figures 4a and 5a show the lock 100 when the door is open.

En référence à la figure 5a, lorsque la porte est ouverte, le palpeur 800 est repoussé vers l'extérieur de la serrure 100 par le deuxième ressort 820. La deuxième extrémité 830 du palpeur 800, n'agit pas sur le deuxième élément de blocage basculant 900.Referring to Figure 5a, when the door is open, the probe 800 is pushed out of the lock 100 by the second spring 820. The second end 830 of the probe 800, does not act on the second locking element tilting 900.

Le deuxième élément de blocage basculant 900 est donc uniquement sollicité par le troisième ressort 930 qui tend à maintenir le deuxième élément de blocage basculant 900 dans la position d'inhibition.The second tilting blocking element 900 is therefore only solicited by the third spring 930 which tends to keep the second tilting blocking element 900 in the inhibition position.

Dans cette position d'inhibition, la première extrémité 920 du deuxième élément de blocage 900 est interposée entre la têtière 110 et une goupille 232 du pêne 200.In this inhibition position, the first end 920 of the second locking element 900 is interposed between the headrest 110 and a pin 232 of the bolt 200.

Il en résulte que le pêne 200 est légèrement rétracté à l'intérieur du boîtier 101, ce qui entrave le déplacement en translation de la queue de pêne 300, soumise à la poussée du rouleau 420 de l'élément de blocage basculant 400, l'élément de blocage basculant 400 étant sollicité par le premier ressort 415.As a result, the bolt 200 is slightly retracted inside the casing 101, which hinders the translational movement of the bolt shank 300, subjected to the thrust of the roller 420 of the tilting blocking element 400, tilting blocking element 400 being biased by the first spring 415.

L'ensemble de blocage mobile 300, 400 est donc inopérant du fait que le rouleau 420 n'atteint pas la face arrière 310 de la queue de pêne 300. Le pêne 200 peut donc pivoter et se rétracter à l'intérieur de la serrure 100.The movable locking assembly 300, 400 is therefore inoperative because the roll 420 does not reach the rear face 310 of the bolt shank 300. The bolt 200 can therefore pivot and retract inside the lock 100 .

Les figures 4b et 5b représentent la serrure 100 pendant la fermeture de la porte lorsqu'une surface d'appui 204 du pêne 200 entre en contact avec l'huisserie de la porte 700. Ceci a pour effet de faire pivoter le pêne 200 de la position de la figure 4a vers la position de la figure 4b, dans laquelle le plan 202 de symétrie du pêne 200 et le plan de symétrie 604 de la biellette 600 sont confondus.FIGS. 4b and 5b show the lock 100 during closing of the door when a bearing surface 204 of the bolt 200 comes into contact with the frame of the door 700. This has the effect of pivoting the bolt 200 from the position of Figure 4a to the position of Figure 4b, wherein the plane 202 of symmetry of the bolt 200 and the plane of symmetry 604 of the link 600 are merged.

En pivotant, la came profilée 212, en contact avec une rampe 330 de la queue de pêne 300, provoque le recul en translation vers l'intérieur de la serrure 100, de la queue de pêne 300, guidée par les pions 302.By pivoting, the profiled cam 212, in contact with a ramp 330 of the bolt shank 300, causes the recess in translation towards the inside of the lock 100, the bolt shank 300, guided by the pins 302.

En même temps, le palpeur 800 entre en contact avec l'huisserie 700 comme représenté figure 5b. Ceci entraîne le recul et le pivotement du palpeur 800 à l'intérieur de la serrure 100. La deuxième extrémité 830 du palpeur 800 entre alors en contact avec la deuxième extrémité 940 du deuxième élément de blocage basculant 900.At the same time, the probe 800 comes into contact with the frame 700 as shown in FIG. 5b. This causes the probe 800 to move back and pivot inside the lock 100. The second end 830 of the probe 800 then comes into contact with the second end 940 of the second tilting blocking element 900.

En poursuivant la fermeture de la porte, et comme représenté figure 5c, la première extrémité 810 du palpeur 800 continue à être repoussée par l'huisserie de la porte vers l'intérieur de la serrure 100. La deuxième extrémité 830 du palpeur 800, appuie alors suffisamment sur la deuxième extrémité 940 du deuxième élément de blocage basculant 900, pour le faire basculer autour de l'axe de rotation 910.Continuing to close the door, and as shown in FIG. 5c, the first end 810 of the probe 800 continues to be pushed back by the door frame towards the inside of the lock 100. The second end 830 of the probe 800, supports then sufficiently on the second end 940 of the second tilting blocking element 900, to tilt around the axis of rotation 910.

En basculant, la première extrémité 920 formant cale du deuxième élément de blocage 900, quitte la position d'inhibition. Elle n'est plus susceptible de s'interposer entre la têtière 110 et une goupille 232 du pêne 200.By tilting, the first end 920 forming wedge of the second locking member 900 leaves the inhibition position. It is no longer likely to interpose between the headrest 110 and a pin 232 of the bolt 200.

La figure 4c représente la serrure 100, après que le deuxième élément de blocage 900 a quitté la position d'inhibition. Depuis la position de la figure 4b, le pêne 200 a pivoté, et une de ses surfaces de butée 208 est en appui sur une paroi 102.Figure 4c shows the lock 100, after the second locking member 900 has left the inhibiting position. From the position of Figure 4b, the bolt 200 has rotated, and one of its abutment surfaces 208 is supported on a wall 102.

Le premier ressort 415 exerce un effort sur le premier élément de blocage basculant 400, et tend à le faire pivoter, autour du premier axe de rotation 410, vers une position où la droite reliant les axes de rotation 410 et 422 est sensiblement parallèle à l'axe de symétrie 604 de la biellette 600.The first spring 415 exerts a force on the first rocking blocking element 400, and tends to rotate it about the first axis of rotation 410, to a position where the straight line connecting the axes of rotation 410 and 422 is substantially parallel to the axis of symmetry 604 of the rod 600.

Le rouleau 420, exerce une poussée sur la face arrière 310 de la queue de pêne 100, qui se déplace en direction de la têtière 110, en translation entre les deux parois parallèles 102 et selon une direction perpendiculaire à la têtière 110. La queue de pêne 300 est guidée dans ce mouvement de translation par les deux pions 302.The roll 420 exerts a thrust on the rear face 310 of the bolt shank 100, which moves towards the headrest 110, in translation between the two parallel walls 102 and in a direction perpendicular to the 110. The bolt shank 300 is guided in this translational movement by the two pins 302.

Ce mouvement de translation de la queue de pêne 300, est transmis à la biellette 600 par l'intermédiaire de l'axe cylindrique 316, qui vient appuyer sur le fond de la découpe allongée 610 de la biellette 600.This translational movement of the bolt shank 300 is transmitted to the link 600 via the cylindrical axis 316, which presses against the bottom of the elongated cutout 610 of the link 600.

Ce mouvement de translation est quant à lui transmis au pêne 200 par l'intermédiaire de l'axe cylindrique 630 reliant la biellette 600 et le pêne 200.This translational movement is in turn transmitted to the bolt 200 via the cylindrical axis 630 connecting the link 600 and the bolt 200.

L'extrémité arrondie 320 de la queue de pêne 200, appuie alors sur un épaulement 210 du pêne 200, ce qui favorise la rotation du pêne 200, jusqu'à la position décrite précédemment dans laquelle une surface de butée 208 est en appui sur une paroi 102.The rounded end 320 of the bolt shank 200, then bears on a shoulder 210 of the bolt 200, which promotes the rotation of the bolt 200, to the previously described position in which an abutment surface 208 is supported on a wall 102.

La figure 4d représente la serrure 100, après la fermeture de la porte. La première extrémité 920 formant cale du deuxième élément de blocage 900 ayant quitté la position d'inhibition, comme décrit en référence à la figure 5c, elle ne s'interpose pas entre la têtière 110 et une goupille 232 du pêne 200.Figure 4d shows the lock 100 after closing the door. Since the first wedge end 920 of the second locking element 900 has left the inhibition position, as described with reference to FIG. 5c, it does not interpose between the headrest 110 and a pin 232 of the bolt 200.

Le pêne 200, est donc repoussé par l'ensemble de blocage 300, 400, jusqu'à ce qu'une goupille 232 vienne en appui sur la face interne 112 de la têtière. Le pêne 200 est repoussé dans la gâche 702 de l'huisserie de la porte 700.The bolt 200 is thus pushed back by the locking assembly 300, 400, until a pin 232 bears on the inner face 112 of the headrest. The bolt 200 is pushed back into the latch 702 of the frame of the door 700.

Les côtes des différents éléments constitutifs de la serrure 100 sont telles que, dans cette position, la droite D définie d'une part par le point de contact 312 entre le rouleau 420 et la face 310 de la queue de pêne 300, et d'autre part par la direction de déplacement de la queue de pêne 300, coupe sensiblement le premier axe de rotation 410 de l'élément basculant 400.The ribs of the various constituent elements of the lock 100 are such that, in this position, the line D defined firstly by the point of contact 312 between the roller 420 and the face 310 of the bolt shank 300, and on the other hand, by the direction of movement of the bolt shank 300, substantially cuts the first axis of rotation 410 of the tilting element 400.

La position de l'élément de blocage basculant 400 définit ainsi une position de blocage du pêne 200. En effet, dans cette position, une poussée de la queue de pêne 300 sur l'élément de blocage basculant 400, génère un couple nul. Il n'est donc pas possible de faire pivoter le pêne 200, puisque cela aurait pour effet, par la liaison de forme décrite précédemment, de générer une poussée sur la queue de pêne 300.The position of the tilting blocking element 400 thus defines a locking position of the bolt 200. Indeed, in this position, a thrust of the bolt shank 300 on the tilting blocking element 400, generates a zero torque. It is therefore not possible to rotate the bolt 200, since this would have the effect, by the form connection described above, to generate a thrust on the bolt tail 300.

La serrure est ainsi bloquée, la porte étant en position fermée.The lock is thus locked, the door being in the closed position.

Le seul moyen pour débloquer la serrure, est de dégager l'élément de blocage basculant 400 de la position de blocage.The only way to unlock the lock, is to release the tilting blocking element 400 from the locking position.

Ceci peut se faire par l'intermédiaire d'une poignée, non représentée ici. Cette poignée comporte un axe enfoncé dans le fouillot 510. En tournant, elle actionne le levier 500, solidaire du fouillot 510.This can be done through a handle, not shown here. This handle has an axis pressed into the follower 510. By turning, it actuates the lever 500, integral with the follower 510.

Le levier 500 appuie dans ce cas sur le rouleau 402 de l'élément de blocage basculant 400, et entraîne son basculement, autour de son premier axe de rotation 410. Le basculement est suffisant pour que la droite D définie précédemment ne coupe plus le premier axe de rotation 410 de l'élément basculant 400.The lever 500 in this case presses on the roll 402 of the rocking blocking element 400, and causes it to tilt around its first axis of rotation 410. The tilting is sufficient so that the straight line D defined above no longer cuts the first axis of rotation 410 of the rocking element 400.

Dans cette position débloquée, une éventuelle poussée de la queue de pêne 300 sur l'élément de blocage basculant 400, génère un couple suffisant sur l'élément de blocage basculant 400, pour le faire basculer. La queue de pêne est ainsi libérée de sa contrainte. Le pêne 200 peut alors pivoter et se rétracter. C'est ce qui se passe lors de l'ouverture de la porte, lorsqu'une surface d'appui 204 du pêne 200 entre en contact avec la surface de la gâche 702 de l'huisserie de la porte.In this unlocked position, a possible thrust of the bolt shank 300 on the tilting blocking element 400, generates a sufficient torque on the tilting blocking element 400, to tilt it. The bolt tail is thus released from its constraint. The bolt 200 can then pivot and retract. This is what happens when the door is opened, when a bearing surface 204 of the bolt 200 comes into contact with the surface of the striker 702 of the frame of the door.

Les différentes étapes de l'ouverture de la porte vont maintenant être décrites en référence d'une part aux figures 6a à 6d, et d'autre part aux figures 5a à 5c déjà décrites.The various steps of the opening of the door will now be described with reference in part to Figures 6a to 6d, and secondly to Figures 5a to 5c already described.

Les figures 6a et 5c représentent la serrure 100 lorsque la porte est fermée. Les positions des pièces de la serrure 100 représentée sur la figure 6a sont identiques à leurs positions sur la figure 4d correspondant à la fin du cycle de fermeture.Figures 6a and 5c show the lock 100 when the door is closed. The positions of the parts of the lock 100 shown in Figure 6a are identical to their positions in Figure 4d corresponding to the end of the closing cycle.

Lorsqu'on ouvre la porte, le pêne 200 commence à tourner à l'intérieur de la gâche 702 de l'huisserie 700 comme représenté figure 6b. Simultanément, la première extrémité 810 du palpeur 800 frotte sur l'huisserie 700.When the door is opened, the bolt 200 begins to rotate inside the latch 702 of the frame 700 as shown in FIG. 6b. Simultaneously, the first end 810 of the probe 800 rubs on the frame 700.

Lorsque l'ouverture de la porte se poursuit, la première extrémité 810 du palpeur 800, perd le contact avec l'huisserie 700, comme représenté à la figure 5b. Le palpeur 800 est alors repoussé vers l'extérieur de la serrure 100 par le deuxième ressort 820.When the opening of the door continues, the first end 810 of the probe 800, loses contact with the frame 700, as shown in Figure 5b. The probe 800 is then pushed out of the lock 100 by the second spring 820.

La deuxième extrémité 830 du palpeur 800 ne sollicite alors plus la deuxième extrémité 940 du deuxième élément de blocage basculant 900, qui sous l'action du troisième ressort 930 retrouve la position d'inhibition.The second end 830 of the probe 800 then no longer biases the second end 940 of the second rocking locking element 900, which under the action of the third spring 930 returns to the inhibiting position.

Ce retour à la position d'inhibition du deuxième élément de blocage basculant 900 a lieu entre les étapes représentées respectivement sur les figures 6b et 6c.This return to the inhibiting position of the second rocking blocking element 900 takes place between the steps represented respectively in FIGS. 6b and 6c.

Lorsque l'on continue à ouvrir la porte et que le pêne 200, ayant continué à pivoter, atteint la position représentée figure 6c, la première extrémité 920 du deuxième élément de blocage basculant 900 est déjà repositionnée en position d'inhibition le long de la têtière 110.When the door is kept open and the bolt 200, having continued to pivot, reaches the position shown in FIG. 6c, the first end 920 of the second tilting blocking element 900 is already repositioned in the inhibition position along the headrest 110.

Ainsi, et comme précédemment décrit, lorsque le double biseau 206 du pêne 200 perd contact avec l'huisserie 700, l'ensemble de blocage mobile (300, 400) ne peut pas prendre la position de blocage du pêne 200.Thus, and as previously described, when the double bevel 206 of the bolt 200 loses contact with the frame 700, the movable locking assembly (300, 400) can not take the locking position of the bolt 200.

La figure 6d représente la porte ouverte. Elle est identique à la figure 6a et ne sera donc pas décrite.Figure 6d shows the open door. It is identical to Figure 6a and will not be described.

La figure 7 représente une variante de réalisation de la serrure selon l'invention.Figure 7 shows an alternative embodiment of the lock according to the invention.

En préliminaire, on notera que les éléments identiques ou similaires à ceux du mode de réalisation précédemment décrit, seront dans la mesure du possible, référencés par les mêmes signes de référence et ne seront pas décrits à chaque fois.As a preliminary, it will be noted that the elements that are identical or similar to those of the embodiment previously described will, as far as possible, be referenced by the same reference signs and will not be described each time.

Le pêne 200a de cette variante de réalisation diffère du pêne 200 précédemment décrit en référence à la figure 2 en ce qu'il ne comporte pas de goupille 232.The bolt 200a of this embodiment differs from the bolt 200 previously described with reference to Figure 2 in that it has no pin 232.

La biellette 600a de cette variante de réalisation diffère de la biellette 600 précédemment décrite en référence à la figure 2 en ce qu'elle comporte deux tétons 232a, symétriques par rapport au plan de symétrie 604. Chacun de ces deux tétons 232a est adapté à se déplacer dans une lumière 103a réalisée dans chacune des parois latérales 102 de la serrure 100.The link 600a of this embodiment differs from the rod 600 previously described with reference to Figure 2 in that it comprises two pins 232a, symmetrical with respect to the plane of symmetry 604. Each of these two pins 232a is adapted to move in a light 103a made in each of the side walls 102 of the lock 100.

La queue de pêne 300a de cette variante de réalisation diffère de la queue de pêne 300 précédemment décrite en référence à la figure 2 en ce que l'épaisseur de ses branches 314, et notamment l'épaisseur de sa branche inférieure 314a a été augmentée, de telle façon que cette branche inférieure 314a soit d'épaisseur supérieure à l'épaisseur de la branche inférieure 222a du pêne 200a.The bolt shank 300a of this embodiment differs from the bolt shank 300 previously described with reference to FIG. 2 in that the thickness of its branches 314, and in particular the thickness of its branch lower 314a has been increased, so that this lower branch 314a is thicker than the thickness of the lower branch 222a of the bolt 200a.

D'autre part, toujours dans cette même variante, le deuxième élément de blocage 900 a été reculé vers l'intérieur de la serrure 100 par rapport à la position qu'il occupait dans le mode de réalisation précédemment décrit, de telle façon que, dans la position d'inhibition, sa première extrémité 920 formant cale prend position devant l'extrémité arrondie 320 de la branche inférieure 314a de la queue de pêne 300a.On the other hand, still in this same variant, the second locking element 900 has been moved back inside the lock 100 with respect to the position it occupied in the embodiment previously described, so that, in the inhibiting position, its first shim end 920 takes up position in front of the rounded end 320 of the lower leg 314a of the bolt shank 300a.

Ainsi, lorsque la porte est ouverte, la position d'inhibition, obtenue dans le mode de réalisation décrit précédemment, par l'interposition de la première extrémité 920 du deuxième élément de blocage 900 entre une goupille 232 et la face interne 112 de la têtière 110, est maintenant obtenue par le position de la première extrémité 920 devant la forme arrondie de la branche inférieure 314a de la queue de pêne 300a.Thus, when the door is open, the position of inhibition, obtained in the embodiment described above, by the interposition of the first end 920 of the second locking element 900 between a pin 232 and the inner face 112 of the headrest 110, is now obtained by the position of the first end 920 in front of the rounded shape of the lower branch 314a of the bolt shank 300a.

Dans cette position en effet, la première extrémité 920 du deuxième élément de blocage 900 entrave le déplacement en translation de la queue de pêne 300a, ce qui rend l'ensemble de blocage mobile 300a 400 inopérant.In this position, in fact, the first end 920 of the second locking element 900 impedes the translational movement of the bolt shank 300a, which makes the movable locking assembly 300a inoperative.

A la fermeture de la porte, et comme décrit précédemment, l'action de la deuxième extrémité 830 du palpeur 800 sur la deuxième extrémité 940 du deuxième élément de blocage basculant 900 fait basculer le deuxième élément de blocage basculant qui quitte sa position d'inhibition.When closing the door, and as described above, the action of the second end 830 of the probe 800 on the second end 940 of the second tilting blocking element 900 tilts the second tilting blocking element which leaves its inhibiting position .

Le rouleau 420 exerce alors une poussée sur la face arrière 310 de la queue de pêne 300 qui se déplace en direction de la têtière 110 et entraîne la biellette 600a et le pêne 200a.The roller 420 then exerts a thrust on the rear face 310 of the bolt shank 300 which moves towards the headrest 110 and drives the link 600a and the bolt 200a.

Dans le mode de réalisation précédemment décrit, le pêne 200 était repoussé par l'ensemble de blocage 300, 400, jusqu'à ce qu'une goupille 232 vienne en appui sur la face interne 112 de la têtière 110.In the embodiment previously described, the bolt 200 was pushed by the locking assembly 300, 400, until a pin 232 bears on the inner face 112 of the headrest 110.

Dans cette variante, le pêne 200a est repoussé par l'ensemble de blocage 300a, 400, jusqu'à ce jusqu'à ce que les tétons 332a de la biellette 600a viennent en appui sur les extrémités 104a des lumières 103a des parois 102a.In this variant, the bolt 200a is pushed back by the locking assembly 300a, 400, until the studs 332a of the link 600a bear on the ends 104a of the lights 103a of the walls 102a.

On peut noter que, grâce à l'invention, la serrure peut prendre, au choix, deux configurations : une première configuration (ici lorsque la porte est ouverte) dans laquelle il est garanti que le pêne peut basculer entre ses deux positions de blocage sans être gêné par l'organe de blocage, et une seconde configuration (ici lorsque la porte est fermée) dans laquelle le pêne est bloqué aussi bien en basculement qu'en rétraction.It can be noted that, thanks to the invention, the lock can take, as desired, two configurations: a first configuration (here when the door is open) in which it is guaranteed that the bolt can switch between its two locking positions without be hampered by the locking member, and a second configuration (here when the door is closed) in which the bolt is blocked both in tilting and retraction.

Au surplus, dans la mesure où, la configuration où l'organe de blocage n'empêche pas le pêne de basculer, celui-ci est empêché de venir complètement en saillie en dehors de la serrure, de sorte que l'axe instantané de basculement est en retrait vis-à-vis de la têtière, et donc que les efforts nécessaires pour ce basculement sont minimisés.In addition, insofar as, the configuration where the locking member does not prevent the bolt from tilting, it is prevented from coming completely protruding out of the lock, so that the instantaneous axis of tilting is recessed vis-à-vis the headrest, and therefore the efforts required for this changeover are minimized.
