Description

La présente invention concerne une serrure de sûreté à clé, notamment pour un véhicule automo­bile.The present invention relates to a key-operated security lock, in particular for a motor vehicle.

Les serrures équipant les portes des véhi­cules automobiles actuels sont constituées en général d'un corps percé d'un alésage cylindrique dans lequel tourillonne un rotor solidaire d'une biellette appelée batteuse, qui entraîne une tige d'actionnement d'un mécanisme de serrure. Des moyens rétractables au moyen d'une clé sont prévus pour verrouiller le rotor en rotation par rapport au corps.The locks equipping the doors of current motor vehicles generally consist of a body pierced with a cylindrical bore in which a rotor secured to a rotor secured to a rod called a thresher, which drives an actuating rod of a lock mechanism. Means retractable by means of a key are provided to lock the rotor in rotation relative to the body.

Ces serrures offrent une résistance à l'ou­verture, par une personne ne possédant pas la clé adéquate, souvent insuffisante. En effet, il est possible d'ouvrir ces serrures soit par la force, en exerçant un couple sur le rotor ou sur le corps de façon à entraîner la batteuse en rotation voire même en arrachant la serrure, soit au moyen d'une clé qui, bien que différente de la clé correspondant à la ser­rure, présente un profil permettant son introduction dans la serrure. Il est également possible d'actionner le mécanisme de serrure en agissant directement sur les moyens qui relient la batteuse à ce mécanisme, par exemple au moyen d'un crochet introduit dans l'espace prévu pour le coulissement d'une vitre équipant ladite porte.These locks offer resistance to opening by a person who does not have the adequate key, which is often insufficient. Indeed, it is possible to open these locks either by force, by exerting a torque on the rotor or on the body so as to drive the threshing machine in rotation or even by tearing off the lock, or by means of a key which , although different from the key corresponding to the lock, has a profile allowing its introduction into the lock. It is also possible to actuate the lock mechanism by acting directly on the means which connect the thresher to this mechanism, for example by means of a hook introduced into the space provided for the sliding of a window fitted to said door.

La présente invention a pour but de remédier aux inconvénients précités : elle vise une serrure de sûreté à clé, notamment pour un véhicule automobile, qui puisse difficilement être arrachée, qui ne puisse pas être ouverte par le seul exercice d'un couple sur le rotor, ni par une action directe sur les moyens de liaison de la batteuse au mécanisme de serrure et dont le profil de la clé présente un nombre important de caractéristiques propres limitant au maximum la pos­sibilité d'ouverture de la serrure au moyen d'une autre clé ou d'un outil quelconque.The object of the present invention is to remedy the aforementioned drawbacks: it is aimed at a key-operated safety lock, in particular for a motor vehicle, which can hardly be torn off, which cannot be opened by the mere exercise of a torque on the rotor. , nor by a direct action on the means of connection of the thresher to the lock mechanism and whose key profile has a large number of its own characteristics limiting as much as possible the opening of the lock by means of another key or any tool.

La serrure selon l'invention comporte :
- un corps percé d'un alésage cylindrique,
- une batteuse logée au fond de l'alésage, mobile en rotation autour de l'axe du corps et soli­daire de moyens d'entraînement d'une tige d'action­nement d'un mécanisme de serrure.The lock according to the invention comprises:
- a body pierced with a cylindrical bore,
- A thresher housed at the bottom of the bore, mobile in rotation around the axis of the body and secured to means for driving an actuating rod of a lock mechanism.

Suivant l'invention, la serrure est carac­térisée en ce qu'elle comprend en combinaison :
- un rotor tubulaire de diamètre extérieur légèrement inférieur au diamètre intérieur de l'alé­sage, déplaçable au moyen d'une clé en translation axiale par rapport au corps entre une position embrayée pour laquelle il est susceptible d'entraîner la batteuse en rotation et une position débrayée;
- des moyens de verrouillage en translation du rotor en position débrayée, rétractables au moyen de la clé;
- des moyens débrayables de blocage en ro­tation du rotor par rapport au corps.According to the invention, the lock is characterized in that it comprises in combination:
- a tubular rotor with an outside diameter slightly smaller than the inside diameter of the bore, movable by means of a key in axial translation relative to the body between a engaged position for which it is capable of driving the threshing machine in rotation and a position disengaged;
means of locking in translation of the rotor in the disengaged position, retractable by means of the key;
- disengageable means for blocking the rotation of the rotor relative to the body.

De préférence, la serrure selon l'invention comporte des moyens de verrouillage en rotation de la batteuse rétractables au moyen de la clé, par exemple constitués par des pistons montés coulissants dans des trous longitudinaux percés dans la batteuse et des contre-pistons montés coulissants dans des logements longitudinaux percés dans le fond du corps avec les mêmes sections et la même disposition que les trous de la batteuse, un ressort étant placé au fond de chaque logement pour solliciter normalement chaque contre­piston dans une position pour laquelle il est contenu partiellement dans son logement et partiellement dans le trou correspondant de la batteuse, l'extrémité de chaque piston opposée au contre-piston étant suscep­tible de coopérer avec un méplat correspondant usiné à l'extrémité de la clé pour placer chaque contre-piston à affleurement de l'interface batteuse-corps.Preferably, the lock according to the invention comprises means for locking in rotation of the threshing machine retractable by means of the key, for example constituted by pistons mounted sliding in longitudinal holes drilled in the threshing machine and counter pistons mounted sliding in longitudinal housings drilled in the bottom of the body with the same sections and the same arrangement as the thresher holes, a spring being placed at the bottom of each housing to normally bias each counter piston in a position for which it is partially contained in its housing and partially in the corresponding hole of the thresher, the end of each piston opposite the counter-piston being capable of cooperating with a corresponding flat machined at the end of the key to place each counter-piston flush with the thresher-body interface.

Les moyens de verrouillage en translation du rotor par rapport au corps sont constitués de préfé­rence par des paillettes montées coulissantes dans des logements radiaux percés dans le corps prolongés par des trous radiaux percés dans le rotor, chaque paillette étant sollicitée normalement par un ressort dans une position pour laquelle elle est contenue partiellement dans son logement et dans le trou correspondant du rotor et étant percée d'un trous susceptible de coopérer avec une encoche de la clé pour amener la paillette dans une position pour laquelle elle est contenue totalement dans le rotor.The means for locking in translation of the rotor relative to the body are preferably constituted by flakes slidably mounted in radial housings drilled in the body extended by radial holes drilled in the rotor, each flake being normally biased by a spring in a position for which it is partially contained in its housing and in the corresponding hole of the rotor and being pierced with a hole capable of cooperating with a notch of the key to bring the straw in a position for which it is completely contained in the rotor.

Suivant un mode de réalisation de l'inven­tion, les logements percés dans le corps sont des gorges circulaires autorisant une rotation du rotor par rapport au corps quelle que soit la position des paillettes dans leurs logements, les moyens débraya­bles de blocage en rotation du rotor par rapport au corps étant de préférence des moyens élastiques per­mettant le débrayage du rotor à partir d'un certain couple.According to one embodiment of the invention, the housings drilled in the body are circular grooves allowing rotation of the rotor relative to the body regardless of the position of the flakes in their housings, the disengageable means for blocking the rotation of the rotor by relative to the body being preferably elastic means allowing the disengagement of the rotor from a certain torque.

Suivant un autre mode de réalisation, les logements percés dans le corps comportent des épaule­ments de blocage des paillettes en rotation par rap­port au corps, les paillettes constituant ainsi à la fois les moyens de blocage en translation et en rota­tion du rotor par rapport au corps. Dans ce mode de réalisation, le corps est avantageusement constitué d'une partie fixe et d'une partie mobile appelée sta­ tor, de diamètre extérieur légèrement inférieur au diamètre intérieur de la partie fixe, bloquée en translation mais mobile en rotation par rapport à cette dernière et munie de moyens de blocage en rotation, ces moyens étant de préférence des moyens élastiques débrayables à partir d'un certain couple.According to another embodiment, the housings drilled in the body comprise shoulders for blocking the flakes in rotation relative to the body, the flakes thus constituting both the means for blocking in translation and in rotation of the rotor with respect to the body. In this embodiment, the body advantageously consists of a fixed part and a mobile part called sta tor, with an outside diameter slightly smaller than the inside diameter of the fixed part, blocked in translation but movable in rotation relative to the latter and provided with rotation blocking means, these means preferably being elastic means which can be disengaged from a certain couple.

Selon d'autres caractéristiques :
- le fond du corps porte une tige saillante dirigée vers l'intérieur de l'alésage, constituant à son extrémité une butée pour les pistons et suscep­tible de s'engager dans un trou correspondant à l'ex­trémité de la clé;
- dans un mode préférentiel, l'alésage est formé à son extrémité opposée à la batteuse par deux volets susceptibles d'être escamotés au moyen de la clé chacun dans un logement ménagé dans le rotor et de revenir automatiquement en position d'obturation de la serrure;
- le rotor est muni d'un doigt susceptible de coopérer avec une encoche de la clé pour entraîner le rotor en rotation;
- la partie du corps avoisinant l'extrémité ouverte de l'alésage est réalisée en un matériau très résistant, tel que de l'acier traité, par exemple de l'acier carbonitruré.According to other characteristics:
- The bottom of the body carries a projecting rod directed towards the inside of the bore, constituting at its end a stop for the pistons and capable of engaging in a hole corresponding to the end of the key;
- In a preferred embodiment, the bore is formed at its end opposite to the thresher by two flaps capable of being retracted by means of the key each in a housing provided in the rotor and automatically return to the closed position of the lock;
- The rotor is provided with a finger capable of cooperating with a notch in the key to drive the rotor in rotation;
- The part of the body surrounding the open end of the bore is made of a very resistant material, such as treated steel, for example carbonitrided steel.

La serrure représentée sur les Figures 1 à 5, destinée notamment à une porte de véhicule automo­bile, comporte un corps 1 percé d'un alésage cylin­drique 2 et terminé par un fond 1a dans lequel est logée une batteuse 3 en forme de disque mobile en rotation autour de l'axe X-X de l'alésage 2, et solidaire de moyens d'entraînement 3a d'une tige 3b d'actionnement d'un mécanisme de serrure, connu en soi et non représenté.The lock shown in FIGS. 1 to 5, intended in particular for a door of a motor vehicle, comprises a body 1 pierced with a cylindrical bore 2 and terminated by a bottom 1a in which is housed a threshing machine 3 in the form of a rotating mobile disc around the axis XX of the bore 2, and integral with drive means 3a of a rod 3b for actuating a lock mechanism, known per se and not shown.

Le corps 1 est ici constitué d'une partie fixe 1b et d'une partie mobile 4, appelée stator, de diamètre extérieur légèrement inférieur au diamètre intérieur de la partie fixe 1b et bloquée en trans­lation par rapport à celle-ci entre deux épaulements 5 et 6.The body 1 here consists of a fixed part 1b and a movable part 4, called a stator, of outer diameter slightly less than the inner diameter of the fixed part 1b and locked in translation relative to the latter between two shoulders 5 and 6.

Le stator 4 est bloqué en rotation par rap­port à la partie fixe 1b du corps 1 par une bille 7 qui est maintenue dans un logement 8 correspondant du corps 1b au moyen d'un ressort 9 mais qui est suscep­tible de sortir du logement 8 à partir d'un certain couple, permettant le débrayage du stator 4 par rap­port à la partie fixe 1b du corps 1.The stator 4 is locked in rotation relative to the fixed part 1b of the body 1 by a ball 7 which is held in a corresponding housing 8 of the body 1b by means of a spring 9 but which is capable of coming out of the housing 8 from of a certain torque, allowing the stator 4 to disengage relative to the fixed part 1b of the body 1.

Un rotor tubulaire 10, de diamètre extérieur légèrement inférieur au diamètre intérieur du stator 4, est déplaçable en translation axiale par rapport au stator 4 entre une position embrayée pour laquelle il est susceptible d'entraîner la batteuse 3 au moyen d'un doigt 11 pénétrant dans une encoche 12 de la batteuse 3, et une position débrayée. Les Figures 1 et 2 montrent le rotor 10 en position débrayée tandis que la Figure 3 le montre en position embrayée.A tubular rotor 10, of outside diameter slightly smaller than the inside diameter of the stator 4, is movable in axial translation relative to the stator 4 between a engaged position for which it is capable of driving the thresher 3 by means of a penetrating finger 11 in a notch 12 of the thresher 3, and a disengaged position. Figures 1 and 2 show the rotor 10 in the disengaged position while Figure 3 shows the rotor in the engaged position.

Des paillettes 13 formées par des plaquettes sont montées coulissantes dans des logements radiaux 14 percés dans le stator 4 et prolongés par des trous radiaux 15 percés dans le rotor 10. Chaque paillette 13 est sollicitée normalement par un ressort 16 dans une position pour laquelle elle est contenue partiellement dans son logement 14 et dans le trou correspondant 15 du rotor 10, illustrée par la Figure 1. Chaque paillette 13 est percée d'un trou 17 sus­ceptible de coopérer avec une encoche 18 de la clé 19 relative à la serrure pour amener la paillette 13 dans une position pour laquelle elle est contenue totale­ment dans le rotor 10 (Figures 2 et 3). De plus, les logements 14 présentent des épaulements 14a de blocage des paillettes 13 en rotation par rapport au stator 4, les paillettes 13 constituant ainsi des moyens de blocage du rotor 10 à la fois en translation et en rotation par rapport au corps 1.Flakes 13 formed by plates are slidably mounted in radial housings 14 drilled in the stator 4 and extended by radial holes 15 drilled in the rotor 10. Each flake 13 is normally biased by a spring 16 in a position for which it is partially contained in its housing 14 and in the corresponding hole 15 of the rotor 10, illustrated in Figure 1. Each straw 13 is pierced with a hole 17 capable of cooperating with a notch 18 of the key 19 relating to the lock to bring the straw 13 in a position for which it is completely contained in the rotor 10 (Figures 2 and 3). In addition, the housings 14 have locking shoulders 14a. flakes 13 in rotation relative to the stator 4, the flakes 13 thus constituting means for locking the rotor 10 both in translation and in rotation relative to the body 1.

Des trous longitudinaux 20 sont percés dans la batteuse 3 avec les mêmes sections et la même disposition que des logements longitudinaux 21 percés dans le fond 1a. Un ressort 22 est placé dans le fond de chaque logement 21 et sollicite normalement un piston 23 par l'intermédiaire d'un contre-piston 24 dans une position pour laquelle son extrémité opposée au contre-piston 24 vient en butée contre l'extrémité d'une tige 25 solidaire du fond 1a. Dans cette posi­tion, le contre-piston 24 est contenu partiellement dans le logement 21 et partiellement dans le trou 20 correspondant de la batteuse 3. L'extrémité de chaque piston 23 opposée au contre-piston 24 est susceptible de coopérer avec un méplat 26 usiné à l'extrémité de la clé 19 pour placer chaque contre-piston 24 à af­fleurement de l'interface batteuse 3 - fond 1a. Dans cette position, l'extrémité de la tige 25 vient se loger dans un trou 27 prévu à l'extrémité de la clé 19. Cette dernière comporte en outre une encoche 28 susceptible de coopérer avec un doigt 29 du rotor 10 pour entraîner celui-ci en rotation.Longitudinal holes 20 are drilled in the thresher 3 with the same sections and the same arrangement as longitudinal housings 21 drilled in the bottom 1a. A spring 22 is placed in the bottom of each housing 21 and normally biases a piston 23 by means of a counter-piston 24 in a position for which its end opposite to the counter-piston 24 abuts against the end d 'a rod 25 secured to the bottom 1a. In this position, the counter-piston 24 is partially contained in the housing 21 and partially in the corresponding hole 20 of the thresher 3. The end of each piston 23 opposite the counter-piston 24 is capable of cooperating with a machined flat 26 at the end of the key 19 to place each counter-piston 24 flush with the thresher interface 3 - bottom 1a. In this position, the end of the rod 25 is housed in a hole 27 provided at the end of the key 19. The latter further comprises a notch 28 capable of cooperating with a finger 29 of the rotor 10 to drive the latter. ci in rotation.

L'alésage 2 est fermé à son extrémité oppo­sée à la batteuse 3 par deux volets 30 et 31 qui sont susceptibles d'être escamotés chacun dans un logement 32, respectivement 33, ménagé dans le rotor 10, et qui comportent des moyens élastiques constitués ici par des ressorts de torsion 30a et 31a, de rappel en po­sition d'obturation de l'alésage 2 lors du retrait de la clé 19.The bore 2 is closed at its end opposite the thresher 3 by two flaps 30 and 31 which are each capable of being retracted in a housing 32, respectively 33, formed in the rotor 10, and which comprise elastic means formed here by torsion springs 30a and 31a, for returning to the closed position of the bore 2 when the key 19 is withdrawn.

Le corps 1 est muni à son extrémité opposée au fond 1a d'un enjoliveur 34 en matière plastique et d'une partie centrale 35 réalisée en un matériau très résistant, tel que par exemple de l'acier carbonitru­ré.The body 1 is provided at its opposite end at the bottom 1a of a plastic cover 34 and a central part 35 made of a very resistant material, such as for example carbonitrided steel.

L'ensemble de la serrure est fixé par des moyens non représentés à une paroi 36 telle qu'une porte de véhicule. Au voisinage de la serrure, cette paroi 36 est renforcée par une tôle 36a soudée à la tôle 36.The entire lock is fixed by means not shown to a wall 36 such as a vehicle door. In the vicinity of the lock, this wall 36 is reinforced by a sheet 36a welded to the sheet 36.

La serrure représentée sur les figures 1 à 5 fonctionne de la façon suivante :The lock shown in Figures 1 to 5 operates as follows:

En position de fermeture, représentée sur la figure 1, les paillettes 13 sont dans des positions pour lesquelles le rotor 10 est verrrouillé en rotation et en translation par rapport au stator 4. Les contre-­pistons 24 sont dans des positions pour lesquelles la batteuse 3 est immobilisée en rotation par rapport au fond du corps 1a. Les volets 30 et 31 sont en position d'obturation de l'alésage 2.In the closed position, shown in FIG. 1, the flakes 13 are in positions for which the rotor 10 is locked in rotation and in translation relative to the stator 4. The counter-pistons 24 are in positions for which the thresher 3 is immobilized in rotation relative to the bottom of the body 1a. The flaps 30 and 31 are in the closed position of the bore 2.

Sur la Figure 3, après escamotage par l'ex­trémité de la clé 19 de forme généralement cônique, des volets 31 et 32, la clé 19 a été introduite dans l'alésage 2 jusqu'a une position pour laquelle les paillettes 13 sont totalement contenues dans le rotor 10 mais pour laquelle les pistons 23 n'ont subi aucun déplacement. Ainsi le rotor 10 est déverrouillé par rapport au stator 4, mais il ne peut entraîner la batteuse 3 en rotation puisque le doigt 11 du rotor 10 se trouve en dehors de l'encoche 12 de la batteuse 3 et que la batteuse 3 est encore verrouillée en rota­tion par rapport au fond 1a.In Figure 3, after retraction by the end of the key 19 of generally conical shape, flaps 31 and 32, the key 19 has been introduced into the bore 2 to a position for which the flakes 13 are completely contained in the rotor 10 but for which the pistons 23 have not undergone any displacement. Thus the rotor 10 is unlocked relative to the stator 4, but it cannot drive the thresher 3 in rotation since the finger 11 of the rotor 10 is located outside the notch 12 of the thresher 3 and the thresher 3 is still locked. in rotation relative to the bottom 1a.

Sur la Figure 4, la clé 19 a été enfoncée jusqu'à une position pour laquelle les contre-pistons 24 se trouvent à affleurement de l'interface batteuse 3 - fond la, et le rotor 10 a subi une translation longitudinale telle que le doigt 11 du rotor 10 se trouve dans l'encoche 12. Il suffit alors de faire tourner la clé 19 pour entraîner le rotor 10 qui à son tour entraîne la batteuse 3 qui actionne le mécanisme de serrure par l'intermédiaire de la tige 3b.In FIG. 4, the key 19 has been pushed in to a position for which the counter-pistons 24 are flush with the thresher interface 3 - the bottom, and the rotor 10 has undergone a longitudinal translation such that the finger 11 of the rotor 10 is in the notch 12. It suffices then to turn the key 19 to drive the rotor 10 which in turn drives the threshing machine 3 which actuates the lock mechanism by means of the rod 3b.

Dans la seconde réalisation de la serrure représentée sur les figures 6 et 7, le corps 1 ne comporte plus de partie mobile ou stator 4 tel que celui des Figures 1 à 5 et les logements radiaux 14 percés dans le corps 1, sont ici constitués de gorges circulaires 14b autorisant une rotation du rotor 10 par rapport au corps 1 quelle que soit la position des paillettes 13 dans leurs logements. Le rotor 10, qui n'est donc plus bloqué en rotation par les paillettes 13, est, dans sa position débrayée, bloqué en rotation par rapport au corps 1, par une bille 7a qui est main­tenue dans une rainure longitudinale 8a correspondante du corps 1 au moyen d'un ressort 9a mais qui est sus­ceptible de sortir de la rainure 8a à partir d'un certain couple. La rainure 8a est terminée, à son ex­trémité la plus proche du fond du corps 1a, par une gorge circulaire 8b qui permet sans effort le déblo­cage en rotation du rotor 10 par rapport au corps 1 lorsque le rotor 10 est en position embrayée d'entraî­nement de la batteuse 3 en rotation.In the second embodiment of the lock shown in Figures 6 and 7, the body 1 no longer has a movable part or stator 4 such as that of Figures 1 to 5 and the radial housings 14 drilled in the body 1, here consist of circular grooves 14b allowing rotation of the rotor 10 relative to the body 1 whatever the position of the flakes 13 in their housings. The rotor 10, which is therefore no longer locked in rotation by the flakes 13, is, in its disengaged position, locked in rotation relative to the body 1, by a ball 7a which is held in a corresponding longitudinal groove 8a of the body 1 by means of a spring 9a but which is capable of coming out of the groove 8a from a certain torque. The groove 8a is terminated, at its end closest to the bottom of the body 1a, by a circular groove 8b which allows effortlessly the release in rotation of the rotor 10 relative to the body 1 when the rotor 10 is in the engaged drive position. of the threshing machine 3 in rotation.

Le fonctionnement de la serrure représenté sur les figures 6 et 7 est analogue à celui des fi­gures 1 à 5 : la seule différence réside dans le fait que, lorsque les paillettes 13 ont été rétractées au moyen de la clé, le rotor 10 est déverrouillé en translation par rapport au corps 1 mais reste bloqué en rotation par la bille 7a. Lorsque le rotor 10 a subi la translation longitudinale amenant son doigt 11 dans l'encoche 12, il est débloqué en rotation par rapport au corps 1 car la bille 7a peut coulisser dans la gorge 8b réalisée dans le corps 1.The operation of the lock shown in Figures 6 and 7 is similar to that of Figures 1 to 5: the only difference is that when the flakes 13 have been retracted by means of the key, the rotor 10 is unlocked in translation relative to the body 1 but remains blocked in rotation by the ball 7a. When the rotor 10 has undergone longitudinal translation bringing its finger 11 in the notch 12, it is released in rotation relative to the body 1 because the ball 7a can slide in the groove 8b produced in the body 1.

La serrure que l'on vient de décrire présente de nombreux avantages :The lock just described has many advantages:

Elle comporte un grand nombre de caracté­ristiques propres déterminées par le nombre de pail­lettes 13 et les dimensions du trou 17 de chacune d'entre elles, le nombre et la longueur des pistons 23, la longueur de la tige 25 et les dimensions de sa partie extrême, la position et les dimensions du doigt 11. Le nombre important de combinaisons possibles diminue d'autant le risque d'ouverture de la serrure par une fausse clé.It has a large number of specific characteristics determined by the number of flakes 13 and the dimensions of the hole 17 of each of them, the number and length of the pistons 23, the length of the rod 25 and the dimensions of its end part. , the position and the dimensions of finger 11. The large number of possible combinations reduces the risk of opening the lock by a false key.

Au cas où une personne réussirait tout de même à introduire dans l'alésage 2 une clé permettant la rétraction des paillettes 13 sans toutefois permet­tre l'effacement des pistons 23, l'ouverture de la serrure ne serait pas possible puisque le rotor 10 ne serait pas en prise avec la batteuse 3 et que cette dernière serait en outre verrouillée par les pistons 23.If a person still succeeds in introducing into the bore 2 a key allowing the retraction of the flakes 13 without however allowing the erasure of the pistons 23, the opening of the lock would not be possible since the rotor 10 would not be not engaged with the thresher 3 and that the latter would also be locked by the pistons 23.

Si on cherche à faire tourner de force le rotor 10, au moyen d'une fausse clé qui ne permet pas la rétraction de toutes les paillettes, ou d'un outil quelconque, le rotor 10 tournera fou sans entraîner le corps 1 ni la batteuse 3. En effet, dans le cas des figures 1 à 5, le stator 4 se trouvera entraîné en même temps que le rotor 10 sans entraîner la partie fixe 1b du corps 1 car la bille 7 sortira du logement 8, désaccouplant ainsi le stator 4 de la partie fixe 1b du corps 1. Après que la serrure ait été forcée de cette manière, lorsque l'on cherchera à ouvrir la serrure au moyen de la clé adéquate, il faudra faire tourner l'ensemble stator-rotor jusqu'à ce que la bille 7 revienne dans son logement 8, avant d'enfoncer complètement la clé. Sans cette rotation préalable, le doigt 11 ne se trouverait pas en face de l'encoche 12. Dans le cas des figures 6 et 7, le rotor 10 tournera fou dans le corps 1 car la bille 7a sortira du logement 8a, désacouplant ainsi le rotor 10 du corps 1. Après que la serrure ait été forcée de cette manière, on procèdera de la même façon que précédem­ment afin de replacer le doigt 11 en face de l'encoche 12. Le fait que la serrure ne soit pas détériorée après que le rotor ait été forcé en rotation présente un avantage substantiel par rapport aux serrures réaisées jusqu'à présent. Il est à noter d'autre part que la forme ronde de l'entrée de la serrure ainsi que la partie 35 renforcée de l'entrée de clé rend plus difficile l'accès au rotor 10.If one seeks to rotate the rotor 10, by means of a dummy key which does not allow the retraction of all the glitter, or of any tool, the rotor 10 will turn mad without driving the body 1 or the thresher 3. Indeed, in the case of FIGS. 1 to 5, the stator 4 will be driven at the same time as the rotor 10 without driving the fixed part 1b of the body 1 because the ball 7 will come out of the housing 8, thus uncoupling the stator 4 of the fixed part 1b of the body 1. After the lock has been forced in this way, when trying to open the lock using the appropriate key, it will be necessary to do turn the stator-rotor assembly until the ball 7 returns to its housing 8, before fully inserting the key. Without this prior rotation, the finger 11 would not be in front of the notch 12. In the case of FIGS. 6 and 7, the rotor 10 will turn madly in the body 1 because the ball 7a will come out of the housing 8a, thus uncoupling the rotor 10 of the body 1. After the lock has been forced in this way, we will proceed in the same way as before in order to replace the finger 11 in front of the notch 12. The fact that the lock is not damaged after the rotor has been forced into rotation has a substantial advantage compared to locks reaisées so far. It should also be noted that the round shape of the lock entry as well as the reinforced part of the key entry makes access to the rotor 10 more difficult.

La serrure selon l'invention peut diffici­lement être arrachée du fait que la paroi 36 est ren­forcée au voisinage de la serrure par la tôle 36a.The lock according to the invention can hardly be torn off because the wall 36 is reinforced in the vicinity of the lock by the sheet 36a.

D'autre part, comme les pistons 23 immobi­lisent la batteuse 3 et donc la tige 3b, il n'est pas possible d'agir directement sur les moyens de liaison de la batteuse au mécanisme de serrure pour ouvrir cette dernière.On the other hand, as the pistons 23 immobilize the thresher 3 and therefore the rod 3b, it is not possible to act directly on the means of connection of the thresher to the lock mechanism to open the latter.

La serrure selon l'invention présente donc l'avantage de pouvoir être très difficilement ouverte au moyen d'une fausse clé ou d'un outil quelconque et de pouvoir être très difficilement forcée ou arrachée. Au cas où le rotor 10 serait tout de même forcé, un moyen de débrayage en rotation (7, 8 ; 7a, 8a) empêche l'ouverture de la serrure sans toutefois détériorer celle-ci.The lock according to the invention therefore has the advantage of being able to be very difficult to open by means of a false key or of any tool and of being able to be very difficult to force or tear off. In the event that the rotor 10 is still forced, a means of declutching in rotation (7, 8; 7a, 8a) prevents the opening of the lock without, however, damaging the latter.

En outre, le fait de réaliser les moyens d'obturation de la serrure par deux volets, 30 et 31, escamotables dans des logements de faible longueur permet de réduire la longueur totale de la serrure.Furthermore, achieving the means closing the lock by two flaps, 30 and 31, retractable in housing of short length reduces the total length of the lock.

Bien entendu, l'invention n'est pas limitée au mode de réalisation qui vient d'être décrit.Of course, the invention is not limited to the embodiment which has just been described.

Ainsi les moyens de verrouillage en rotation du rotor pourraient être constitués d'ergots coopérant avec des gorges réalisées dans la clé ou bien par un ensemble de pistons et de contre-pistons.Thus the means for locking the rotor in rotation could consist of lugs cooperating with grooves made in the key or else by a set of pistons and counter-pistons.
