Abstract

The lock comprises two independent coaxial cams (511a,511b) between which is a rotating operating lever (525) which activates the locking system of the lock bolt. Each cam engages the lever through selective coupling mechanisms (514a,514b) themselves activated by a cam (515a,516b,518a,518b).

Description

L'invention concerne une serrure à montage universel ou "sans main", c'est-à-dire susceptible d'être montée indifféremment sur une porte ouvrant à gauche ou une porte ouvrant à droite.The invention relates to a lock with universal mounting or "without hand", that is to say capable of being mounted either on a door opening to left or a door opening to the right.

L'invention concerne plus particulièrement un perfectionnement permettant d'adapter le fouillot à la "main" choisie, pour que la serrure puisse se monter, par exemple, sur la porte d'une issue de secours , laquelle doit pouvoir être ouverte de l'intérieur mais doit restée verrouillée de l'extérieur.The invention relates more particularly to an improvement to adapt the follower to the "hand" chosen, so that the lock can be mount, for example, on the door of an emergency exit, which must be able be open from the inside but must remain locked from the outside.

Un autre aspect de l'invention concerne la commande d'un tel fouillot adaptable, par un cylindre de clé.Another aspect of the invention relates to the control of such a follower adaptable, by a key cylinder.

Selon une autre caractéristique simplement avantageuse, l'invention concerne aussi l'agencement d'un pêne dormant pivotant, commandé par le fouillot et/ou le cylindre de clé.According to another simply advantageous characteristic, the invention also relates to the arrangement of a pivoting deadbolt, controlled by the follower and / or key cylinder.

Plus particulièrement, l'invention concerne une serrure à montage universel dite "sans main" comprenant, dans un boítier un pêne biseauté et un système de blocage dudit pêne, caractérisée en ce qu'elle comporte deux fouillots coaxiaux et indépendants l'un de l'autre entre lesquels est agencé un levier de manoeuvre rotatif apte à actionner ledit système de blocage et en ce que chaque fouillot coopère avec ledit levier par des mécanismes de couplage respectifs, eux-mêmes actionnés par des cames respectives.More particularly, the invention relates to a mounting lock universal called "without hand" including, in a case a beveled bolt and a locking system of said bolt, characterized in that it comprises two coaxial and independent of each other between which is arranged a rotary operating lever capable of actuating said locking system and in this that each follower cooperates with said lever by coupling mechanisms respective, themselves actuated by respective cams.

Selon un mode de réalisation préféré, chaque fouillot peut être sélectionné au moyen d'une première came positionnable installée pour commander un tel mécanisme de couplage agencé entre le fouillot en question et ledit levier de manoeuvre afin d'adapter la serrure au sens d'ouverture de la porte sur laquelle elle est montée. La serrure comporte donc deux premières cames de ce genre, une pour chaque fouillot.According to a preferred embodiment, each follower can be selected by means of a first positionable cam installed for order such a coupling mechanism arranged between the follower in question and said operating lever in order to adapt the lock to the direction of opening of the door on which it is mounted. The lock therefore has two first cams of this kind, one for each follower.

Selon une autre caractéristique avantageuse de l'invention, la serrure comporte une seconde came installée pour commander un tel mécanisme de couplage agencé entre chaque fouillot et ledit levier de manoeuvre, chaque seconde came étant lié à une pièce de transmission, mobile à l'intérieur du boítier de ladite serrure et agencé pour être soumise à l'action d'un cylindre de clé. Ainsi, la serrure comporte aussi deux secondes cames correspondant respectivement à chaque fouillot et ces deux cames sont actionnées simultanément par la pièce de transmission elle-même déplacée par le paneton du cylindre de clé. Dans une position, les deux dites secondes cames commandent ensemble le couplage ou le découplage entre chaque fouillot et le levier de manoeuvre. Si lesdites secondes cames ne peuvent interférer avec le mécanisme de couplage, pour une position donnée de ladite pièce de transmission, seul le fouillot effectivement commandé par la première came est couplé par celle-ci au levier de manoeuvre ; la porte ne peut s'ouvrir qu'avec ce fouillot. Si en revanche les deux secondes cames sont au contact des deux mécanismes de couplage, les deux fouillots sont "actifs" et la porte peut être ouverte aussi bien de l'intérieur que de l'extérieur.According to another advantageous characteristic of the invention, the lock has a second cam installed to control such a mechanism coupling arranged between each follower and said operating lever, each second cam being linked to a transmission part, movable inside the case of said lock and arranged to be subjected to the action of a cylinder of key. Thus, the lock also includes two second cams corresponding respectively to each follower and these two cams are actuated simultaneously by the transmission part itself moved by the bit of the key cylinder. In one position, the two so-called second cams together control the coupling or decoupling between each follower and the operating lever. If said second cams cannot interfere with the coupling mechanism, for a given position of said piece of transmission, only the follower actually controlled by the first cam is coupled by the latter to the operating lever; the door can only be opened with this follower. If, on the other hand, the two second cams are in contact with the two coupling mechanisms, the two slots are "active" and the door can be open both from the inside and the outside.

Selon une autre caractéristique remarquable, un mécanisme de couplage précité, agencé entre chaque fouillot et ledit levier de manoeuvre comprend un cliquet articulé audit levier de manoeuvre du côté du fouillot correspondant et une dent définie à la périphérie dudit fouillot.According to another remarkable characteristic, a coupling mechanism above, arranged between each follower and said operating lever comprises a pawl articulated to said operating lever on the side of the corresponding follower and a tooth defined at the periphery of said follower.

En outre, lesdites première et seconde cames correspondant à un même mécanisme de couplage agencé entre un fouillot et ledit levier de manoeuvre sont montées côte à côte et coopèrent avec un même cliquet. L'épaisseur de ce cliquet est sensiblement égale à la somme des épaisseurs des premières et secondes cames correspondantes.In addition, said first and second cams corresponding to the same coupling mechanism arranged between a follower and said operating lever are mounted side by side and cooperate with the same pawl. The thickness of this ratchet is substantially equal to the sum of the thicknesses of the first and second corresponding cams.

Les premières et secondes cames sont montées coaxialement sur un tourillon commun monté rotatif entre deux parois parallèles du boítier. Les deux dites premières cames sont solidaires en rotation du tourillon et décalées angulairement l'une par rapport à l'autre. Par conséquent, la position de ce tourillon détermine ladite première came qui associe de façon permanente le levier de manoeuvre et le fouillot sélectionné. Bien entendu, ce fouillot sélectionné est celui qui se trouve du côté intérieur ; le fouillot extérieur restant fou lorsque la porte est fermée.The first and second cams are mounted coaxially on a common pin rotatably mounted between two parallel walls of the housing. Both said first cams are integral in rotation with the journal and offset angularly one relative to the other. Therefore, the position of this pin determines said first cam which permanently associates the operating lever and the follower selected. Of course, this follower selected is the one on the inside; the remaining external follower crazy when the door is closed.

Dans un mode de réalisation spécifique, le tourillon comporte des méplats ou analogues avec lesquels coopère un ressort de positionnement pour définir deux positions stables dudit tourillon et desdites premières cames. Une telle première came est donc en position d'actionner le mécanisme de couplage qui lui correspond pour l'une desdites positions stables dudit tourillon, respectivement. En revanche, les deux dites secondes cames sont montées en rotation libres sur le tourillon et elles sont parallèles entre elles. Chaque seconde came est munie d'un bras en prise avec ladite pièce de transmission.In a specific embodiment, the pin has flats or the like with which a positioning spring cooperates to define two stable positions of said journal and said first cams. Such a first cam is therefore in position to activate the coupling mechanism which corresponds to it for one of said stable positions of said journal, respectively. On the other hand, the two so-called second cams are mounted in free rotation on the pin and they are parallel to each other. Each second cam is provided with an arm engaged with said transmission part.

Le tourillon comporte un moyen de manoeuvre permettant de le placer dans l'une ou l'autre desdites positions stables. Ce moyen de manoeuvre ne peut être accessible qu'avant montage de la serrure sur la porte.The trunnion has an operating means allowing it to be placed in either of said stable positions. This means of maneuver cannot be accessible only before mounting the lock on the door.

L'invention sera mieux comprise et d'autres avantages de celles-ci apparaítront mieux à la lumière de la description qui va suivre d'une serrure dite "sans main" conforme à son principe, donnée uniquement à titre d'exemple et faite en référence aux dessins annexés dans lesquels :

La serrure 100 comporte un boítier 101 muni de deux parois parallèles 102 et une têtière 110 perpendiculaire aux deux parois parallèles 102. L'une des parois est constituée par le foncet ou couvercle du boítier. L'autre paroi constitue la paroi de fond du coffre dans lequel sont installés les éléments du mécanisme de serrure. Le boítier 101 est représenté ouvert de sorte que seule l'une des parois 102 est visible sur cette figure. La serrure comporte un pêne pivotant à double biseau 200 qui sera décrit plus loin en référence à la figure 2. Elle comporte aussi un ensemble de blocage mobile constitué d'une queue de pêne 300 et d'un élément de blocage basculant 400. La largeur de la queue de pêne 300 est telle qu'elle puisse 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 les deux parois 102 et par deux pions 302 s'étendant perpendiculairement à celles-ci.The lock 100 comprises a housing 101 provided with two parallel walls 102 and a headrest 110 perpendicular to the two parallel walls 102. One of the walls is formed by the box or cover of the housing. The other wall constitutes the bottom wall of the trunk in which the elements of the lock mechanism. The housing 101 is shown open so that only one of the walls 102 is visible in this figure. The lock has a bolt pivoting double bevel 200 which will be described later with reference to FIG. 2. It also includes a movable blocking assembly consisting of a tail bolt 300 and a tilting blocking element 400. The width of the tail bolt 300 is such that it can slide in a translational movement between the two parallel walls 102, in a direction perpendicular to the headrest 110. The bolt tail 300 is guided in this translational movement by the two walls 102 and by two pins 302 extending perpendicular to them.

L'élément de blocage basculant 400 comporte un axe de rotation 410 s'étendant perpendiculairement aux parois 102. Il est sollicité élastiquement par un ressort 415 vers une position de blocage du pêne 200. Cet élément de blocage comporte un rouleau 420 adapté à tourner autour d'un axe de rotation 422 perpendiculaire aux parois 102. Le rouleau 420 est susceptible d'exercer une poussée sur une face 310 de la queue de pêne 300, à l'arrière de celle-ci. Lorsqu'elle est soumise à cette poussée, la queue de pêne 300 peut se déplacer en translation, guidée par les deux pions 302. La position de blocage précitée est atteinte lorsque le rouleau 420 prend appui sensiblement au milieu de la face d'extrémité 310 de la queue de pêne.The tilting blocking element 400 has an axis of rotation 410 extending perpendicular to the walls 102. It is elastically stressed by a spring 415 towards a bolt locking position 200. This element of blocking comprises a roller 420 adapted to rotate about an axis of rotation 422 perpendicular to the walls 102. The roller 420 is capable of exerting a push on a face 310 of the bolt tail 300, at the rear of the latter. When subjected to this thrust, the bolt tail 300 can move in translation, guided by the two pins 302. The aforementioned blocking position is reached when the roller 420 bears substantially in the middle of the face end 310 of the bolt tail.

La figure 2 représente le pêne 200, la queue de pêne 300 et une biellette 600 reliant ces deux éléments. Le pêne 200 comporte deux surfaces d'appui 204, symétriques par rapport au plan de symétrie 202 du pêne 200 et formant un double biseau 206. Les surfaces d'appui 204 sont adaptées à prendre appui sur la gâche de l'huisserie d'une porte (non représentée). 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.Figure 2 shows the bolt 200, the bolt tail 300 and a link 600 connecting these two elements. The bolt 200 has two bearing surfaces 204, symmetrical with respect to the plane of symmetry 202 of the bolt 200 and forming a double bevel 206. The bearing surfaces 204 are adapted to bear on the strike of the door frame (not shown). Each of the surfaces support 204 is extended by a curved surface and then by a stop surface 208, parallel to the other bearing surface 204 and capable of bearing on a wall 102.

Chaque surface d'appui 208 est prolongée par un épaulement 210. Les surfaces de butée 208 et les épaulements 210 sont symétriques par rapport aux plans de symétrie 202 du pêne 200. Les épaulements 210 sont symétriques par rapport au plan de symétrie 202 du pêne 200. Les épaulements 210 sont prolongés par une came profilée 212 symétrique par rapport au plan de symétrie 202 du pêne 200. Ce dernier comporte un autre plan de symétrie 214, orthogonal au plan de symétrie 202. Le pêne 200 comporte un évidement 220 s'étendant de part et d'autre du plan de symétrie 214 définissant dans le pêne deux branches 222. Ces deux branches sont traversées par un trou 224 dont l'axe est contenu dans le plan de symétrie 202.Each bearing surface 208 is extended by a shoulder 210. The abutment surfaces 208 and shoulders 210 are symmetrical with respect to planes of symmetry 202 of the bolt 200. The shoulders 210 are symmetrical by relative to the plane of symmetry 202 of the bolt 200. The shoulders 210 are extended by a profiled cam 212 symmetrical with respect to the plane of symmetry 202 of the bolt 200. The latter comprises another plane of symmetry 214, orthogonal to the plane of symmetry 202. The bolt 200 has a recess 220 extending on either side of the plane of symmetry 214 defining in the bolt two branches 222. These two branches are crossed by a hole 224 of which the axis is contained in the plane of symmetry 202.

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

La queue de pêne comporte un évidement 340 lui donnant un profil en forme de U dont la face 310 constitue la base.The bolt tail has a recess 340 giving it a profile in U-shaped whose face 310 constitutes the base.

Les deux branches 314 de cette pièce en U sont reliées par une goupille cylindrique 316 traversant l'évidement 340. L'axe de la goupille 316 est contenu dans le plan de symétrie 304. La biellette 600 comporte deux faces parallèles et deux côtés parallèles, perpendiculaires à ces deux faces, respectivement en contact avec les parois 102. Elle admet un plan de symétrie 604. A proximité d'une de ces extrémités 601, la biellette 600 est traversée par un trou cylindrique 620. L'axe de ce trou est contenu dans le plan de symétrie 604. Le diamètre de ce trou est sensiblement de la taille du trou 224 du pêne 200.The two branches 314 of this U-shaped part are connected by a pin cylindrical 316 passing through the recess 340. The axis of the pin 316 is contained in the plane of symmetry 304. The link 600 has two parallel faces and two parallel sides, perpendicular to these two faces, respectively in contact with the walls 102. It admits a plane of symmetry 604. Nearby from one of these ends 601, the link 600 is crossed by a cylindrical hole 620. The axis of this hole is contained in the plane of symmetry 604. The diameter of this hole is substantially the size of hole 224 of the bolt 200.

La biellette 600 comporte une découpe 610 allongée longitudinalement, symétrique par rapport au plan 604 et débouchant sur une extrémité opposée à l'extrémité 601. Le fond de cette découpe est arrondi. Sa largeur est légèrement supérieure au diamètre de la goupille 316 de la queue de pêne. L'épaisseur de la biellette 600 est légèrement inférieure à la hauteur de l'évidement 340 et à la hauteur de l'évidement 220. La goupille 316 peut ainsi se déplacer en translation dans la découpe allongée 610 de la biellette 600, les plans de symétrie 604 et 304 étant confondus.The link 600 has a cut 610 elongated longitudinally, symmetrical about the plane 604 and opening at an end opposite to the end 601. The bottom of this cut is rounded. Its width is slightly greater than the diameter of the pin 316 of the bolt tail. The thickness of the rod 600 is slightly less than the height of the recess 340 and the height of the recess 220. The pin 316 can thus move in translation in the elongated cutout 610 of the link 600, the planes of symmetry 604 and 304 being combined.

La biellette 600 est placée dans l'évidement 220 du pêne de sorte que les trous 620 et 224 soient alignés. Ces trous sont traversés par un axe cylindrique 630 permettant une articulation entre la biellette 600 et le pêne 200. L'axe 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 link 600 is placed in the recess 220 of the bolt so that the holes 620 and 224 are aligned. These holes are crossed by a cylindrical axis 630 allowing an articulation between the link 600 and the bolt 200. The axis 630 can for example be mounted tight in the hole 224 of the bolt 200 and mounted sliding in the hole 620 of the link 600.

L'extrémité 320 de la queue de pêne 300 est conformée pour glisser le long de l'un ou l'autre des épaulements 210 du pêne 200. La came profilée 212 du pêne est elle-même conformée pour glisser le long des deux rampes 330 de la queue de pêne 300. Cet agencement définit une liaison de forme entre le pêne 200 et la queue de pêne 300 qui permet de bloquer le pêne pivotant dans l'une ou l'autre de deux positions stables. Ce pêne est traversé par deux percements 230 parallèles à la têtière et symétrique par rapport au plan 202. Ces percements sont situés entre le trou 224 et les épaulements 210. The end 320 of the bolt tail 300 is shaped to slide the along one or other of the shoulders 210 of the bolt 200. The profiled cam 212 of the bolt is itself shaped to slide along the two ramps 330 of the bolt tail 300. This arrangement defines a form connection between the bolt 200 and the bolt tail 300 which allows the pivoting bolt to be locked in either of two stable positions. This bolt is crossed by two openings 230 parallel to the headrest and symmetrical with respect to the plane 202. These holes are located between the hole 224 and the shoulders 210.

Deux goupilles 232 sont emmanchées à force dans les percements 230 et font saillie d'une face supérieure du pêne 200.Two pins 232 are force-fitted into the holes 230 and protrude from an upper face of the bolt 200.

Deux autres goupilles 232 sont emmanchées à force dans les percements 230 par une face inférieure du pêne 200 et font saillie de cette face. Ces goupilles 232 sont adaptées à prendre appui sur une face interne 112 de la têtière 110.Two other pins 232 are forced into the holes 230 by a lower face of the bolt 200 and project from this face. These pins 232 are adapted to bear on an internal face 112 of the headrest 110.

La serrure 100 comporte des moyens d'inhibition 800, 900 comprenant notamment un palpeur 800 dont une extrémité 810 en forme de double biseau, fait saillie hors de la têtière 110 et d'un élément de blocage basculant 900, d'autre part. L'élément de blocage basculant 900 comporte un axe de rotation 910 et une 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. L'élément de blocage basculant 900 est sollicité par un ressort 930 qui tend à ramener l'élément de blocage basculant dans ladite position d'inhibition.The lock 100 includes inhibiting means 800, 900 comprising in particular a feeler 800, one end 810 of which is in the form of a double bevel, protrudes from the headrest 110 and a tilting blocking element 900, on the other hand. The tilting blocking element 900 has an axis of rotation 910 and an end 920 forming a shim, adapted to be interposed in a position called inhibition, between a pin 232 of the bolt 200 and the headrest 110. The element tilting blocking device 900 is biased by a spring 930 which tends to bring back the locking element tilting in said inhibition position.

Le palpeur 800 est sollicité de façon élastique vers l'extérieur de la serrure, par un ressort 820. Ce palpeur comporte un ergot 812, parallèle à la têtière 110, qui prend appui sur une face interne 112 de celle-ci, sous la sollicitation du ressort 820, lorsque la porte est ouverte, c'est à dire lorsque le palpeur 800 n'est pas en contact avec l'huisserie de cette porte. Le palpeur 800, est donc adapté à se rétracter à l'intérieur de la serrure, à l'encontre de la sollicitation du ressort 820, lorsque la porte se ferme. Dans ce cas, son extrémité interne 830 rencontre une extrémité 940 de l'élément de blocage basculant 900, ce qui entraíne sa rotation autour de l'axe 810 et lui fait quitter ladite position d'inhibition, comme représenté sur la figure 1.The probe 800 is resiliently biased towards the outside of the lock, by a spring 820. This probe has a lug 812, parallel to the headrest 110, which rests on an internal face 112 thereof, under the stress on spring 820, when the door is open, i.e. when the feeler 800 is not in contact with the door frame. The 800 probe, is therefore suitable for retracting inside the lock, against the stress on spring 820, when the door closes. In this case, his internal end 830 meets one end 940 of the locking element tilting 900, which causes it to rotate around axis 810 and cause it to exit said inhibition position, as shown in FIG. 1.

Selon une caractéristique importante de l'invention, la serrure comporte deux fouillots 511a, 511b coaxiaux et indépendants l'un de l'autre, entre lesquels est agencé un levier de manoeuvre rotatif 512 apte à actionner ledit système de blocage et plus particulièrement l'élément de blocage 400 de celui-ci. Chaque fouillot comporte un trou à section carrée 520 apte à recevoir une tige à section carrée (non représentée) d'une poignée de manoeuvre. Le levier de manoeuvre 512 est une pièce plate qui comporte une extrémité d'actionnement 525 coopérant avec un rouleau 402 de l'élément de blocage basculant 400. Cette pièce plate comporte un trou cylindrique 521 dont l'axe se confond avec l'axe de rotation de la pièce plate elle-même. Chaque fouillot 511a, 511b comporte une partie centrale cylindrique au milieu de laquelle s'inscrit le trou 520 à section carrée. Chaque face circulaire de ladite partie centrale cylindrique est munie d'un épaulement périphérique. L'épaulement extérieur 526 prend appui sur le bord d'un trou circulaire pratiqué dans la paroi de fond du coffre ou dans celle du foncet, respectivement. L'épaulement intérieur 527 prend appui sur le bord du trou cylindrique 521 du levier de manoeuvre rotatif 512. Les deux trous circulaires (non visibles sur les dessins) pratiqués dans la paroi du fond du coffre et dans le foncet admettent le même axe et, bien entendu, la distance qui sépare les deux épaulements extérieurs 526 des deux fouillots, lorsqu'ils sont montés de part et d'autre du levier de manoeuvre 512, correspond à la distance qui sépare le foncet de la paroi de fond du coffre de sorte que les deux fouillots et le levier tournent autour d'un axe commun. L'empilement axial de ces trois pièces, correspondant à la distance qui sépare le foncet de la paroi de fond du coffre, assure à la fois le montage des pièces dans le boítier et leur guidage en rotation.According to an important characteristic of the invention, the lock comprises two spindles 511a, 511b coaxial and independent of each other, between which is arranged a rotary operating lever 512 able to actuate said system of blocking and more particularly the blocking element 400 thereof. Each follower has a square section hole 520 capable of receiving a section rod square (not shown) of an operating handle. The operating lever 512 is a flat part which has an actuating end 525 cooperating with a roller 402 of the tilting blocking element 400. This flat part has a cylindrical hole 521 whose axis merges with the axis of rotation of the flat part itself. Each follower 511a, 511b has a cylindrical central part in the middle of which is inscribed the section hole 520 square. Each circular face of said cylindrical central part is provided with a peripheral shoulder. The outer shoulder 526 rests on the edge a circular hole made in the bottom wall of the trunk or in that of the foncet, respectively. The inner shoulder 527 rests on the edge of the cylindrical hole 521 of the rotary operating lever 512. The two holes circular (not visible in the drawings) made in the bottom wall of the boot and in the fonet admit the same axis and, of course, the distance between the two outer shoulders 526 of the two nuts, when they are mounted on both sides of the operating lever 512, corresponds to the distance between the back of the trunk wall so that the two spindles and the lever revolve around a common axis. The axial stacking of these three parts, corresponding to the distance between the wall and the back wall of the trunk, ensures both the mounting of the parts in the housing and their rotation guidance.

Les deux fouillots 511a, 511b sont séparés par une rondelle 522 en acier dur qui empêche le passage d'une tige unique, à section carrée, au travers de la serrure. Cette rondelle 522 est logée dans le trou 521. Chaque fouillot comporte un crochet 530 faisant saillie de son chant extérieur. Un ressort 531 porté par un support fixé audit boítier coopère avec ces deux crochets pour solliciter les deux fouillots 511a, 511b en rotation, ici dans le sens inverse des aiguilles d'une montre en considérant la figure 1.The two pins 511a, 511b are separated by a washer 522 made of steel hard which prevents the passage of a single rod, with square section, through the lock. This washer 522 is housed in the hole 521. Each follower has a hook 530 projecting from its outer edge. A spring 531 carried by a support fixed to said housing cooperates with these two hooks to urge the two rotating pins 511a, 511b, here counterclockwise shown by considering figure 1.

Il ressort clairement de la figure 1 que la rotation du levier de manoeuvre rotatif 512 (dans le sens des aiguilles d'une montre en considérant cette figure) permet de faire pivoter l'élément de blocage 400 et plus particulièrement de lui faire quitter ladite position de blocage.It is clear from Figure 1 that the rotation of the operating lever rotary 512 (clockwise when considering this figure) allows the locking element 400 to be pivoted and more particularly to it leave said blocking position.

Chaque fouillot coopère avec le levier de manoeuvre rotatif par des mécanismes de couplage sélectif 514a, 514b respectifs, eux-mêmes actionnés par des cames 516a, 516b - 518a, 518b, respectives. Un tel mécanisme de couplage, agencé entre un fouillot et ledit levier de manoeuvre 512 comprend un cliquet 532a, 532b articulé audit levier de manoeuvre du côté du fouillot correspondant et une dent 534a, 534b définie à la périphérie dudit fouillot et faisant saillie de son chant périphérique. Les deux cliquets sont montés pivotants aux deux extrémités d'une tige 533 elle-même engagée dans un trou excentré 535 du levier de manoeuvre 512. De cette façon, lorsque le cliquet et la dent d'un fouillot sont en prise, ce fouillot et le levier 512 sont solidaires en rotation pour une manoeuvre selon un sens de rotation s'opposant à celui vers lequel le ressort sollicite ledit fouillot.Each follower cooperates with the rotary operating lever by means of respective selective coupling mechanisms 514a, 514b, themselves actuated by cams 516a, 516b - 518a, 518b, respectively. Such a mechanism of coupling, arranged between a follower and said operating lever 512 comprises a ratchet 532a, 532b articulated to said operating lever on the follower side corresponding and a tooth 534a, 534b defined at the periphery of said follower and protruding from its peripheral song. The two pawls are pivotally mounted at the two ends of a rod 533 itself engaged in an eccentric hole 535 of the operating lever 512. In this way, when the pawl and the tooth of a follower are engaged, this follower and the lever 512 are integral in rotation for an operation in a direction of rotation opposing that towards which the spring requests said follower.

Pour chaque fouillot, une première came positionnable, 516a, 516b est installée pour commander un tel mécanisme de couplage 514a, 514b, correspondant, agencé entre le fouillot concerné et ledit levier de manoeuvre. Lesdites premières cames 516a, 516b sont solidaires en rotation d'un même tourillon 536 et décalées angulairement l'une par rapport à l'autre. Ainsi, lorsque l'une des cames est en position de commander le mécanisme de couplage qui lui correspond, l'autre ne l'est pas, ce qui permet d'adapter la serrure au sens d'ouverture de la porte sur laquelle elle est montée, comme on le verra plus loin. Le tourillon 536 comporte en fait deux parties d'extrémité cylindriques 540 et une partie centrale à contour carré 541. Les cames 516a, 516b sont fixées de part et d'autre de cette partie centrale qui définit donc des méplats 542 ou analogues avec lesquels coopère la branche terminale d'un ressort de positionnement 543 monté dans le coffre. Cet agencement permet de définir deux positions stables dudit tourillon et par conséquent desdites premières cames qui sont solidaires de celui-ci. Ainsi, chacune des premières cames est en position d'actionner le mécanisme de couplage qui lui correspond pour une position stable correspondante dudit tourillon, respectivement. Le tourillon comporte un moyen de manoeuvre permettant de le placer dans l'une ou l'autre de ces positions stables. Dans l'exemple, ce moyen de manoeuvre est constitué d'une simple fente 544 transversale ménagée au bout de l'une des parties d'extrémité cylindriques du tourillon. Cette fente est accessible à l'extérieur du boítier et permet de manoeuvrer le tourillon à l'aide d'un tournevis. L'actionnement du tourillon permet de sélectionner la première came qui doit être en permanence en contact avec le cliquet correspondant, ce qui permet de sélectionner la "main" de la serrure.For each follower, a first positionable cam, 516a, 516b is installed to control such a coupling mechanism 514a, 514b, corresponding, arranged between the follower concerned and said operating lever. Said first cams 516a, 516b are integral in rotation with the same pin 536 and offset angularly with respect to each other. So when one of the cams is in position to control the coupling mechanism which corresponds to it, the other is not, which makes it possible to adapt the lock to the direction opening of the door on which it is mounted, as will be seen below. Trunnion 536 in fact comprises two cylindrical end portions 540 and a central part with square outline 541. The cams 516a, 516b are fixed on the side and other of this central part which therefore defines flats 542 or the like with which the end branch of a positioning spring 543 cooperates mounted in the trunk. This arrangement makes it possible to define two stable positions of said journal and consequently of said first cams which are integral with this one. Thus, each of the first cams is in position to actuate the matching coupling mechanism for a stable position corresponding to said journal, respectively. The journal has a means maneuver to place it in either of these positions stable. In the example, this operating means consists of a simple transverse slot 544 formed at the end of one of the end parts cylindrical of the journal. This slot is accessible outside the case and allows you to operate the trunnion using a screwdriver. The actuation of the pin allows selection of the first cam which must be permanently in contact with the corresponding pawl, which allows to select the "hand" of the lock.

En outre, pour chaque fouillot, une seconde came 518a, 518b est installée pour commander un mécanisme de couplage 514a, 514b correspondant, agencé entre le fouillot concerné et ledit levier de manoeuvre. Chaque seconde came est liée à une pièce de transmission 538, mobile à l'intérieur du boítier de la serrure et agencée pour être soumise à l'action d'un cylindre de clé. Sur les dessins, ledit cylindre n'est pas représenté. Il s'agit d'un cylindre classique dit "européen" dont le profil correspond à celui d'une découpe 539 visible à la partie inférieure du coffre. On rappelle qu'un tel cylindre incorpore un panneton lequel, mobile en rotation à l'intérieur du boítier, coopère avec le bord inférieur 546 de la pièce de transmission 538. Les deux dites secondes cames 518a, 518b sont montées coaxialement sur le même tourillon 536 que les premières cames. Ce tourillon commun est monté rotatif entre les deux parois parallèles 102 du boítier. Les deux secondes cames 518a, 518b sont agencées parallèlement l'une à l'autre et sont donc propres à coopérer simultanément avec les deux cliquets correspondants. Chaque seconde came comporte un bras 548 engagé dans un créneau pratiqué dans une partie repliée de la pièce de transmission, coulissant le long de la face intérieure du chant arrière du coffre.In addition, for each follower, a second cam 518a, 518b is installed to control a corresponding coupling mechanism 514a, 514b, arranged between the follower concerned and said operating lever. Every second cam is linked to a transmission part 538, movable inside the lock housing and arranged to be subjected to the action of a key cylinder. In the drawings, said cylinder is not shown. It is a classic cylinder called "European" whose profile corresponds to that of a cutout 539 visible at the bottom from the trunk. It is recalled that such a cylinder incorporates a bit which, movable in rotation inside the housing, cooperates with the lower edge 546 of the workpiece transmission 538. The two so-called second cams 518a, 518b are mounted coaxially on the same pin 536 as the first cams. This journal common is rotatably mounted between the two parallel walls 102 of the housing. The two second cams 518a, 518b are arranged parallel to each other and are therefore suitable for cooperating simultaneously with the two pawls correspondents. Each second cam has an arm 548 engaged in a slot in a folded part of the transmission part, sliding along the inside of the rear edge of the trunk.

Lesdites secondes cames sont montées en rotation autour des parties d'extrémité cylindriques 540 dudit tourillon, respectivement. Elles sont parallèles entre elles et leurs bras 548 sont en prise avec ladite pièce de transmission. Lesdites première et seconde cames qui correspondent à un même mécanisme de couplage 514a ou 514b sont montées côte à côte sur le tourillon et coopèrent avec un même cliquet 532a ou 532b. Plus précisément, l'épaisseur dudit cliquet est sensiblement égale à la somme des épaisseurs des première et seconde cames correspondantes lesquelles sont montées côte à côte, ladite première came étant solidaire du tourillon tandis que la seconde tourne autour de celui-ci, sous la commande du déplacement de ladite pièce de transmission 538. Lesdites premières et secondes cames sont pourvues d'excentriques d'actionnement, conformés pour repousser le cliquet correspondant vers la dent du fouillot avec laquelle ils coopèrent.Said second cams are mounted in rotation around the parts cylindrical end 540 of said journal, respectively. They are parallel between them and their arms 548 are engaged with said transmission part. Said first and second cams which correspond to the same mechanism coupling 514a or 514b are mounted side by side on the trunnion and cooperate with the same ratchet 532a or 532b. More specifically, the thickness of said pawl is substantially equal to the sum of the thicknesses of the first and second corresponding cams which are mounted side by side, said first cam being integral with the journal while the second revolves around it, under the control of the movement of said transmission part 538. Said first and second cams are provided with eccentrics actuation, shaped to push the corresponding pawl towards the tooth of the follower with which they cooperate.

Par ailleurs, la serrure comporte une pièce de verrouillage 550 permettant de maintenir ladite pièce de transmission 538 dans une position pour laquelle lesdites secondes cames 518a, 518b ne peuvent interagir avec lesdits mécanismes de couplage sélectif. C'est la situation illustrée sur la figure 5. Dans cette position la pièce de transmission 538 est maintenue en position haute par la pièce de verrouillage 550. Pour ce faire, la pièce de transmission comporte une patte repliée 552 ou butée analogue qui coopère avec le chant de la pièce de verrouillage. Celle-ci comporte un élément en forme de portion de disque monté rotatif dans le boítier et sollicité en rotation dans un sens prédéterminé par l'action d'un ressort 553. Ici, le sens prédéterminé est le sens inverse de celui des aiguilles d'une montre en considérant les figures 5 à 7. Plus précisément, la pièce de verrouillage comporte une portion de disque de grand diamètre 554, une large échancrure 555 formant ici une portion de disque de moindre diamètre et un ergot radial 556 faisant saillie de cette dernière. Cet ergot est susceptible de coopérer avec un coulisseau de déverrouillage 557 installé dans le boítier (mobile verticalement en considérant les dessins) pour pouvoir être soulevé sous la commande du panneton appartenant au cylindre de clé. Plus précisément, le coulisseau 557 comporte une patte repliée 558 et une butée 559 définie par son propre contour. Cette butée est susceptible d'entraíner l'ergot 556 en rotation dans le sens inverse de celui vers lequel la pièce de verrouillage est sollicitée par son propre ressort. La patte repliée 558 du coulisseau est quant à elle susceptible d'entrer en contact avec le panneton du cylindre lorsque celui-ci est actionné à l'ouverture sous l'action d'une clé.Furthermore, the lock has a locking piece 550 allowing to maintain said transmission part 538 in a position for which said second cams 518a, 518b cannot interact with said selective coupling mechanisms. This is the situation illustrated in Figure 5. In this position the transmission part 538 is held in the high position by the locking part 550. To do this, the transmission part comprises a folded tab 552 or similar stop which cooperates with the edge of the part lock. This includes a disc-shaped element rotatably mounted in the housing and urged to rotate in a predetermined direction by the action of a spring 553. Here, the predetermined direction is the opposite direction of that of the hands of a watch considering Figures 5 to 7. More specifically, the locking piece has a large disc portion diameter 554, a wide notch 555 here forming a disc portion of smaller diameter and a radial lug 556 projecting from the latter. This lug is capable of cooperating with an unlocking slide 557 installed in the case (movable vertically considering the drawings) for be able to be lifted under the control of the bit belonging to the cylinder of key. More specifically, the slide 557 has a folded tab 558 and a stop 559 defined by its own contour. This stop is likely to cause the lug 556 rotating in the opposite direction to that towards which the part of locking is acted upon by its own spring. The folded tab 558 of the slide is likely to come into contact with the bit of the cylinder when the latter is actuated upon opening under the action of a key.

En revanche, lorsque ce même cylindre est actionné à la fermeture sous l'action d'une clé, le panneton rencontre le bord 546 de la partie inférieure de la pièce de transmission et soulève cette dernière ce qui a pour effet de faire pivoter les secondes cames 518a, 518b jusqu'à une position où elles ne peuvent interagir avec les mécanismes de couplage sélectif, c'est-à-dire une position où aucune desdites secondes cames ne peut soulever le cliquet correspondant. On va maintenant décrire le fonctionnement de la serrure, en référence aux figures 5 à 7. Sur la figure 5, la serrure a été fermée à clé et la pièce de transmission 538 se trouve bloquée en position haute par la pièce de verrouillage 550. La patte repliée 552 de la pièce de transmission prend appui sur la partie de plus grand diamètre de la pièce de verrouillage. Dans ces conditions, lesdites secondes cames ne peuvent contribuer à solidariser en rotation les fouillots et le levier pivotant 512. Seul le fouillot intérieur 511a, sélectionné par la première came 516a correspondante est effectivement solidaire en rotation dudit levier pivotant. Par conséquent, la porte est verrouillée de l'extérieur mais peut être ouverte de l'intérieur. On the other hand, when this same cylinder is actuated when closing under the action of a key, the bit meets the edge 546 of the lower part of the transmission part and raises it which has the effect of making rotate the second cams 518a, 518b to a position where they cannot interact with selective coupling mechanisms, i.e. a position where none of said second cams can lift the corresponding pawl. We will now describe the operation of the lock, with reference to Figures 5 to 7. In FIG. 5, the lock has been locked and the transmission part 538 is locked in the high position by the locking piece 550. The tab folded 552 of the transmission part rests on the largest part diameter of the locking piece. Under these conditions, said seconds cams cannot contribute to securing in rotation the spindles and the lever swivel 512. Only the internal follower 511a, selected by the first cam 516a corresponding is effectively integral in rotation with said pivoting lever. Therefore, the door is locked from the outside but can be opened from inside.

Si on veut déverrouiller la porte pour qu'elle puisse être ouverte de l'extérieur, il faut manoeuvrer le cylindre à l'aide d'une clé. Cette manoeuvre est illustrée par les figures 6 et 7. Dans un premier temps, le panneton du cylindre soulève le coulisseau de déverrouillage 557 (qui pourrait aussi être une pièce pivotante) ce qui a pour effet de faire tourner la pièce de verrouillage 550 à l'encontre de la sollicitation du ressort. Ce mouvement se poursuit jusqu'à ce que la patte repliée 552 de la pièce de transmission perde le contact avec la portion de plus grand diamètre de la pièce de verrouillage et retombe dans l'échancrure 555 jusqu'à venir en contact avec la portion de plus petit diamètre. Cette abaissement de la pièce de transmission se traduit par un pivotement desdites secondes cames 518a, 518b de sorte que, cette fois, les deux cliquets viennent en prise respectivement avec les dents des deux fouillots correspondants. C'est la situation illustrée sur la figure 7. Dans cette configuration, les deux fouillots sont couplés avec le levier central pivotant de sorte que la porte peut être ouverte de l'intérieur comme de l'extérieur. Entre-temps, le coulisseau 557 est revenu en position basse. Pour refermer la porte à clé (pour empêcher une ouverture de l'extérieur), il suffira de redonner un tour de clé dans le sens correspondant, ce qui se traduira par un soulèvement de la pièce de transmission, une perte de contact entre la patte 552 et la pièce de verrouillage 550 et une rotation de celle-ci, sous l'action de son propre ressort, pour retourner à la situation illustrée sur la figure 4.If you want to unlock the door so that it can be opened from outside, the cylinder must be operated with a wrench. This maneuver is illustrated by Figures 6 and 7. First, the bit of the cylinder lifts release slide 557 (which could also be a part which has the effect of rotating the locking piece 550 to against the request of the spring. This movement continues until the folded tab 552 of the transmission part loses contact with the portion larger diameter of the locking piece and falls back into the notch 555 until it comes into contact with the portion of smaller diameter. This lowering the transmission part results in a pivoting of said second cams 518a, 518b so that this time the two pawls come engaged respectively with the teeth of the two corresponding spindles. It is the situation illustrated in figure 7. In this configuration, the two diggers are coupled with the pivoting central lever so that the door can be open from the inside and outside. Meanwhile, slide 557 is returned to the low position. To close the door with a key (to prevent opening from the outside), it will suffice to give a turn of the key in the direction corresponding, which will result in an uplift of the coin transmission, loss of contact between lug 552 and the locking part 550 and a rotation thereof, under the action of its own spring, to return to the situation illustrated in Figure 4.
