Abstract

The padlock consists of a combination of a body (10) with an internal bore (11), a control cylinder (30) with rotor/stator of a structure known per se housed in the bore, and a detachable locking unit (100). One end of the locking unit is adapted in such a way that it can be inserted into the bore in the body and is in the shape of a cylindrical rod with an annular groove (108) forming a narrowed portion. Means for locking (40) are also housed in the bore (11) of the body (10) and are moved by the rotor of the control cylinder between a retracted rest position in which the means for locking clear the bore of the body so as to permit the insertion of the locking unit into this bore and the retraction of this locking unit, and an operating position in which the means for locking (40) protrude into the bore (11) and penetrate the annular groove (108) of the locking unit (100). The latter position prevents the retraction of the locking unit (100) while allowing it to turn freely around the axis (12) of the bore. <IMAGE>

Description

La présente invention concerne le domaine des serrures mobiles, c'est-à-dire le domaine des serrures non fixées à demeure sur un vantail de porte, fenêtre ou autre accessoire à verrouiller.The present invention relates to the field of mobile locks, that is to say the field of locks not permanently fixed to a door leaf, window or other accessory to be locked.

On a déjà proposé de nombreuse serrures mobiles. Ces serrures ont déjà rendu de grands services. Néanmoins, les serrures mobiles jusqu'ici proposées pré­sentant un inconvénient majeur. En effet, ces serrures mobiles possèdent généralement un organe de verrouillage en forme d'anse qui, en position fermée de la serrure, est solidarisé en deux points avec le corps de la serrure. De ce fait l'organe de verrouillage des serrures mobiles jusqu'ici proposées peut être attaqué par torsion à l'aide d'un simple levier, et ainsi détérioré.Numerous mobile locks have already been proposed. These locks have already done great service. Nevertheless, the mobile locks hitherto proposed having a major drawback. Indeed, these movable locks generally have a locking member in the form of a handle which, in the closed position of the lock, is secured at two points with the body of the lock. Therefore the locking member of the mobile locks hitherto proposed can be attacked by torsion using a simple lever, and thus damaged.

Le but principal de la présente invention est de proposer une nouvelle serrure simple, robuste et écono­mique et surtout dans laquelle l'organe de verrouillage ne puisse être attaqué par torsion.The main object of the present invention is to provide a new simple, robust and economical lock, and above all in which the locking member cannot be attacked by torsion.

Un autre but de la présente invention est de proposer une serrure mobile adaptable à différents modè­les d'organes de verrouillage, c'est-à-dire susceptible de recevoir des organes de verrouillage présentant des forme, diamètre ou longueur différents.Another object of the present invention is to provide a movable lock adaptable to different models of locking members, that is to say capable of receiving locking members having different shape, diameter or length.

Ces différents buts sont atteints dans le cadre de la présente invention grâce à une serrure mobile comprenant en combinaison :
- un corps muni d'un alésage interne,
- un cylindre de commande à rotor/stator de structure connue en soi, logé dans l'alésage,
- un organe de verrouillage amovible dont une extrémité, adaptée pour être insérée dans l'alésage du corps, a la forme d'une tige cylindrique munie d'une rainure annulaire formant rétrécissement, et
- des moyens de blocage logés également dans l'alésage du corps et déplacés par le rotor du cylindre de commande entre une position de repos escamotée dans laquelle les moyens de blocage libèrent l'alésage du corps pour permettre l'insertion de l'organe de verrouillage dans cet alésage et le retrait de cet organe, et une position de travail dans laquelle les moyens de blocage font saillie dans l'alésage et pénètrant dans la rainure annulaire de l'organe de verrouillage pour interdir le retrait de celui-ci tout en autorisant une libre rotation de cet organe autour de l'axe de l'alésage.These various aims are achieved within the framework of the present invention by means of a movable lock comprising in combination:
- a body with an internal bore,
- a rotor / stator control cylinder of known structure, housed in the bore,
a removable locking member, one end of which, adapted to be inserted into the bore of the body, has the shape of a cylindrical rod provided with an annular groove forming a narrowing, and
- locking means also housed in the bore of the body and moved by the rotor of the control cylinder between a retracted rest position in which the locking means release the bore of the body to allow the insertion of the locking in this bore and the withdrawal of this member, and a working position in which the blocking means protrude into the bore and penetrating into the annular groove of the locking member to prohibit the withdrawal thereof while allowing free rotation of this member about the axis of the bore.

Grâce à la présente invention du fait que l'organe de verrouillage est solidarisé en un seul point avec le corps de la serrure d'une part, et que en position de fermeture de la serrure l'organe de verrouillage reste libre de rotation d'autre part, l'organe de verrouillage et par conséquent la serrure mobile ne peuvent être atta­qués par torsion à l'aide d'un levier comme cela était le cas par le passé.Thanks to the present invention, the fact that the locking member is secured at a single point with the body of the lock on the one hand, and that in the closed position of the lock the locking member remains free to rotate. on the other hand, the locking member and therefore the movable lock cannot be attacked by twisting with the aid of a lever as was the case in the past.

Selon une caractéristique avantageuse de la présente invention le corps de la serrure possède une enveloppe extérieure convexe incurvée de façon continue sans arête. Ainsi, de préférence le corps possède une enveloppe extérieure de révolution autour de l'axe de l'alésage interne, choisi dans le groupe comprenant les formes : ovoïde, cylindrique et sphérique.According to an advantageous characteristic of the present invention, the body of the lock has a continuously curved convex outer envelope without edges. Thus, preferably the body has an outer envelope of revolution around the axis of the internal bore, chosen from the group comprising the shapes: ovoid, cylindrical and spherical.

Selon une caractéristique préférentielle de la présente invention, les moyens de blocage comprennent au moins un élément en forme générale de demi-couronne logé dans une portion de l'alésage non symétrique de révolution par rapport à l'axe de celui-ci. Plus précisé­ment encore, les moyens de blocage de la serrure mobile conforme à la présente invention comprennent avantageusement deux éléments en forme générale de demi-couronne logés dans une portion en forme générale d'ellipse.According to a preferred characteristic of the present invention, the locking means comprise at least one element in the general shape of a half-crown housed in a portion of the bore that is not symmetrical of revolution with respect to the axis thereof. More precisely still, the means for blocking the movable lock according to the present invention advantageously comprise two elements in the general shape of a half-crown housed in a portion in the general shape of an ellipse.

On aperçoit en vue éclatée sur la figure 1, d'une part, un corps 10 qui loge un cylindre de sûreté 30 à rotor/stator et des moyens de blocage 40 actionnés par le cy­lindre 30 et, d'autre part, un organe de verrouillage 100.An exploded view can be seen in FIG. 1, on the one hand, a body 10 which houses a safety cylinder 30 with rotor / stator and blocking means 40 actuated by the cylinder 30 and, on the other hand, a member for lock 100.

Selon le mode de réalisation illustré sur la figure 1, le corps 10 loge de plus une pièce intermédiaire d'entraînement 50 intercalée entre le cylindre 30 et les moyens de blocage 40 ainsi qu'un bouchon tubulaire 70.According to the embodiment illustrated in FIG. 1, the body 10 also houses an intermediate drive part 50 interposed between the cylinder 30 and the locking means 40 as well as a tubular plug 70.

Le corps 10 est formé d'une pièce et possède une enveloppe convexe incurvée de façon conti­nue sans arête.The body 10 is formed in one piece and has a continuously curved convex envelope without edges.

Le corps 10 posséde un alésage étagé traversant 11.Sur les figures l'axe central de l'alésage 11 est référencé 12.The body 10 has a stepped through bore 11. In the figures, the central axis of the bore 11 is referenced 12.

De préférence, l'enveloppe du corps 10 est symétrique de révolution par rapport à l'axe 12 précité. Avantageusement, l'enveloppe extérieure du corps 10 est choisie dans le groupe comprenant les formes ovoïde, cylindrique et sphérique.Preferably, the envelope of the body 10 is symmetrical in revolution with respect to the above-mentioned axis 12. Advantageously, the outer envelope of the body 10 is chosen from the group comprising the ovoid, cylindrical and spherical shapes.

Selon la répresentation de la figure 1, le corps 10 a ainsi une forme générale ovoïde de révo­lution autour de l'axe 12. L'alésage 11 débouche aux deux extrémités de plus faible section du corps 10. L'une des extrémités de l'alésage 11,dite première extrémité par la suite et référencée 13 permet l'accès au cylindre de sûreté 30. L'autre extrémité de l'alésage 11,dite seconde extrémité par la suite et référencée 14 sur les figures, permet un libre engagement de l'organe de verrouillage 100 dans la serrure.According to the representation of FIG. 1, the body 10 thus has a general ovoid shape of revolution around the axis 12. The bore 11 opens at the two ends of smaller section of the body 10. One of the ends of the bore 11, said first end subsequently and referenced 13 allows access to the safety cylinder 30. The other end of bore 11, said second end thereafter and referenced 14 in the figures, allows a free engagement of the locking member 100 in the lock.

De la première extrémité 13 vers la seconde extrémité 14,l'alésage 11 présente successivement :
- une première portion 15 de section droite cylindrique de faible rayon,
- une seconde portion 16 de section droite cylindrique tronquée par deux plans 17 parallèles entre eux et parallèles à l'axe 12, la seconde portion 16 possédant un rayon supé­rieur à celui de la première portion 15,
- une troisième portion 18 de section droite cylindrique possédant un rayon au moins égal à celui de la seconde portion 16 et avantageusement égal à celui-ci pour prolon­ger cette seconde portion 16,
- une quatrième portion 19 de section droite en forme générale d'oval ou d'ellipse dont le petit axe est sensiblement égal au diamètre de la troisième portion 18 précitée,
- une cinquième portion 20 en forme de rainure annulaire de section triangulaire,
- enfin, une sixième portion 21 de section droite cylin­drique dont le rayon est au moins égal à celui de la seconde portion 16 et de la troisième portion 18 en étant avantageusement égal à ceux-ci ; la sixième portion 21 est par ailleurs taraudée intérieurement.From the first end 13 towards the second end 14, the bore 11 successively has:
a first portion 15 of cylindrical cross section of small radius,
a second portion 16 of cylindrical cross section truncated by two planes 17 parallel to each other and parallel to the axis 12, the second portion 16 having a radius greater than that of the first portion 15,
a third portion 18 of cylindrical cross section having a radius at least equal to that of the second portion 16 and advantageously equal to the latter to extend this second portion 16,
a fourth portion 19 of cross section in the general shape of an oval or ellipse, the minor axis of which is substantially equal to the diameter of the aforementioned third portion 18,
a fifth portion 20 in the form of an annular groove of triangular section,
- Finally, a sixth portion 21 of cylindrical cross section whose radius is at least equal to that of the second portion 16 and the third portion 18, being advantageously equal to these; the sixth portion 21 is also internally tapped.

La seconde portion 16 est destinée à recevoir le cylindre de sûreté à rotor/stator 30.The second portion 16 is intended to receive the rotor / stator safety cylinder 30.

La première portion cylindrique 15 permet l'accès au cylindre 30 pour la commande de celui-ci. Dans le cas d'un cylindre à clé, cette première portion 15 permet d'insérer la clé dans le cylindre 30. Dans le cas d'un cylindre à combinaison, la première portion cylin­drique 15 permet d'accéder à l'organe rotatif de décodage de celui-ci.The first cylindrical portion 15 allows access to the cylinder 30 for the control thereof. In the case of a key cylinder, this first portion 15 allows the key to be inserted into the cylinder 30. In the case of a combination cylinder, the first cylindrical portion 15 provides access to the rotary member of decoding of it.

La troisième portion 18 reçoit la pièce inter­médiaire d'entraînement 50 libre de rotation autour de l'axe 12 de la serrure.The third portion 18 receives the intermediate drive piece 50 free to rotate about the axis 12 of the lock.

La quatrième portion 19 reçoit les moyens de blocage 40 libres de déplacement entre la position de repos escamotée(figure 2a) et la position de travail (figure 2b).The fourth portion 19 receives the locking means 40 free to move between the retracted rest position (FIG. 2a) and the working position (FIG. 2b).

Enfin, les cinquième et sixième portions reçoivent le bouchon tubulaire, la cinquième portion en forme de rainure étant plus précisément destinée à recevoir l'extrémité avant d'une vis de pression permettant d'immobiliser le bouchon dans l'alésage 11 du corps.Finally, the fifth and sixth portions receive the tubular plug, the fifth groove-shaped portion being more specifically intended to receive the front end of a pressure screw making it possible to immobilize the plug in the bore 11 of the body.

Le cylindre de sûreté 30 comprend un stator 32 qui enveloppe un rotor 34. Ce dernier émerge à l'arrière du stator 32 par un prolongement 36 non cylindrique de révolution, par exemple un prolongement cylindrique tronqué par un plan 35 parallèle à l'axe cylindrique, ou carré.The safety cylinder 30 comprises a stator 32 which envelops a rotor 34. The latter emerges at the rear of the stator 32 by a non-cylindrical extension 36 of revolution, for example a cylindrical extension truncated by a plane 35 parallel to the cylindrical axis , or square.

Le cylindre 30 peut être un cylindre à combinaison tel que décrit dans la demande de brevet français déposée le 8.02.1985 sous le N.85 01804 ou la demande de brevet européen N. 83 400367.5 déposée le 22 février 1983 et publiée sous le N. 008 812, ou encore un cylindre à clé tel que décrit et illustré par exemple dans la demande de brevet français publiée sous le N. 2 343 107.The cylinder 30 can be a combination cylinder as described in the French patent application filed on 8.02.1985 under N.85 01804 or the European patent application N. 83 400367.5 filed on February 22, 1983 and published under N. 008 812, or even a key cylinder as described and illustrated for example in the French patent application published under N. 2,343,107.

La structure de ces cylindres classique en soi ne sera pas décrite en détail par la suite. On rappellera simplement que dans le cas des cylindres à clé, la clé de taille correcte doit être introduite dans les cylindres pour permettre la rotation du rotor par rapport au stator, tandis que dans le cas d'un cylindre à combinaison, la combinaison correcte doit être composée à l'aide de l'organe de décodage pour permettre cette rotation du rotor par rapport au stator.The structure of these conventional cylinders per se will not be described in detail below. It will simply be recalled that in the case of key cylinders, the correct size key must be introduced into the cylinders to allow rotation of the rotor relative to the stator, while in the case of a combination cylinder, the correct combination must be composed using the decoding member to allow this rotation of the rotor relative to the stator.

Le stator est immobilisé en rotation autour de l'axe 12 dans l'alésage 11 du corps 10.The stator is immobilized in rotation about the axis 12 in the bore 11 of the body 10.

Plus précisément, le stator 32 a une enveloppe complémentaire de la seconde portion 16 de l'alésage 11. En l'espèce l'enveloppe du stator 32 est formée d'un cylindre tronqué par deux plans parallèles 38. En général le stator 32 est de plus fileté en périphérie.More specifically, the stator 32 has a casing complementary to the second portion 16 of the bore 11. In the present case the casing of the stator 32 is formed by a cylinder truncated by two parallel planes 38. In general the stator 32 is more threaded at the periphery.

La pièce intermédiaire d'entraînement 50 intercalée entre le cylindre 30 et les moyens de blocage 40 est formée d'une couronne 51 possédant un alésage central 50 complémentaire de la section droite du prolon­gement 36 du cylindre. La couronne 51 est engagée sur ce prolongement 36 pour être liée en rotation avec ce dernier. La couronne 51 possède, du côté cylindre 30, et sur une partie seulement de son épaisseur une découpe 53 présentant une ouverture angulaire, autour de l'axe de la couronne de l'ordre de 90°.The intermediate drive part 50 interposed between the cylinder 30 and the locking means 40 is formed of a ring 51 having a central bore 50 complementary to the cross section of the extension 36 of the cylinder. The crown 51 is engaged on this extension 36 to be linked in rotation with the latter. The crown 51 has, on the cylinder side 30, and on only part of its thickness a cutout 53 having an angular opening, around the axis of the crown of the order of 90 °.

Les surfaces latérales de cette découpe 53 présentant une ouverture angulaire de l'ordre de 90° sont référencées 57 et 58 sur la figure 1.The lateral surfaces of this cutout 53 having an angular opening of the order of 90 ° are referenced 57 and 58 in FIG. 1.

Lors de l'assemblage de la serrure cette découpe 53 est engagée sur un téton 37 solidaire de la face arrière du stator 32. Ainsi, la rotation du rotor 34 et de la pièce intermédiaire d'entraînement 50 (liée en rotation à ce dernier) par rapport au stator 32 est limitée à une amplitude de l'ordre de 90° déterminée par la venue en butée des surfaces latérales 57, 58 res­pectivement contre le téton 37. La découpe 53 en combi­naison avec le téton 37 constitue un limiteur de course classique pour le rotor 34. Sur l'autre face, opposée au cylindre 30, la couronne 51 est munie de deux ergots 55, 56 diamètralement opposés. Ces ergots 55, 56 sont destinés à déplacer les moyens de blocage 40 entre la position de repos escamotée et la position de travail comme cela sera décrit plus en détail par la suite.When assembling the lock, this cutout 53 is engaged on a stud 37 secured to the rear face of the stator 32. Thus, the rotation of the rotor 34 and of the intermediate drive part 50 (linked in rotation to the latter) relative to the stator 32 is limited to an amplitude of the order of 90 ° determined by the abutment of the lateral surfaces 57, 58 respectively against the stud 37. The cutout 53 in combination with the stud 37 constitutes a conventional stroke limiter for the rotor 34. On the other face, opposite the cylinder 30, the crown 51 is provided with two diametrically opposed lugs 55, 56. These lugs 55, 56 are intended to move the locking means 40 between the retracted rest position and the working position as will be described in more detail below.

Selon le mode de réalisation illustré sur la figure 1, les moyens de blocage 40 sont formés de deux structures en forme générale de demi-couronnes 42, 44. La surface extérieure, cylindrique de préférence, des demi-couronnes 42, 44 est référencée 47, 48 respectivement, tandis que la surface interne, également cylindrique de préférence, des demi-couronnes 42, 44 est référencée 45, 46 respectivement. Plus précisément, les deux demi-­couronnes 42, 44 présentent au niveau de leur surface extérieure 47, 48 une ouverture angulaire inférieure à 180° pour former un cercle complet en position de tra­vail, comme cela est représenté sur la figure 2b, lorsque les ergots 55, 56 sont intercalés entre lesdites demi-­couronnes 42, 44. Plus précisément encore, l'ouverture angulaire de chacune des demi-couronnes 42, 44 est égale à 180° moins l'ouverture angulaire des ergots 55, 56 par rapport au centre de la couronne 51.According to the embodiment illustrated in Figure 1, the locking means 40 are formed of two structures in the general shape of half-rings 42, 44. The outer surface, preferably cylindrical, of the half-rings 42, 44 is referenced 47 , 48 respectively, while the inner surface, also cylindrical of preferably, half-rings 42, 44 are referenced 45, 46 respectively. More specifically, the two half-rings 42, 44 have at their external surface 47, 48 an angular opening of less than 180 ° to form a complete circle in the working position, as shown in FIG. 2b, when the pins 55, 56 are interposed between said half-rings 42, 44. More precisely still, the angular opening of each of the half-rings 42, 44 is equal to 180 ° minus the angular opening of the pins 55, 56 relative to the center of the crown 51.

Le rayon extérieur de la couronne 51 cor­respond sensiblement, tout en étant légèrement inférieur, au rayon de la troisième portion 18 de l'alésage 11. De même, l'épaisseur de la couronne 51 considérée parallèle­ment à l'axe 12 correspond sensiblement, tout en étant légèrement inférieur, à la longueur de cette troisième portion 18.The outer radius of the crown 51 corresponds substantially, while being slightly less, to the radius of the third portion 18 of the bore 11. Likewise, the thickness of the crown 51 considered parallel to the axis 12 corresponds substantially, while being slightly less than the length of this third portion 18.

Le rayon de l'enveloppe externe 47, 48 des demi-couronnes 42, 44 correspond sensiblement, tout en étant légèrement inférieur, à la demi-longueur du petit axe de la quatrième portion 19 de l'alésage 11, petit axe coïncidant avec le plan de coupe III-III.The radius of the outer casing 47, 48 of the half-rings 42, 44 corresponds substantially, while being slightly less, to the half-length of the minor axis of the fourth portion 19 of the bore 11, minor axis coinciding with the section plan III-III.

Plus précisément encore, cette quatrième portion 19 en forme générale d'oval ou d'ellipse est formée selon le mode de réalisation représenté sur les figures 6 et 7 de deux calottes hémicylindriques opposées 22, 23, centrées sur des axes respectifs disposés de part et d'autre du plan de coupe III-III et coïncidant avec le plan de coupe V-V, calottes hémicylindriques 22, 23 reliées par deux plans opposés 24, 25 parallèles au plan de coupe V-V et donc à l'axe longitudinal 12 de la serrure. Le rayon des calottes hémicylindriques précitées 22, 23 cor­respond sensiblement, tout en étant légèrement supérieur, au rayon extérieur des surfaces 47, 48 des demi-couronnes 42, 44. La structure des demi-couronnes 42, 44 et de la portion 19, conforme au mode de réalisation représenté sur la figure 1, sera décrite plus en détail par la suite.More precisely still, this fourth portion 19 in the general shape of an oval or an ellipse is formed according to the embodiment shown in FIGS. 6 and 7 of two opposite semi-cylindrical caps 22, 23, centered on respective axes arranged on the side and other of the section plane III-III and coinciding with the section plane VV, semi-cylindrical caps 22, 23 connected by two opposite planes 24, 25 parallel to the section plane VV and therefore to the longitudinal axis 12 of the lock. The radius of the abovementioned semi-cylindrical caps 22, 23 corresponds substantially, while being slightly greater, to the outer radius of the surfaces 47, 48 of the half-crowns 42, 44. The structure of the half-rings 42, 44 and of the portion 19, according to the embodiment shown in FIG. 1, will be described in more detail below.

Le bouchon 70 tubulaire est formé d'un cyilindre à paroi épaisse délimitant une chambre interne traversante 72. La surface externe 71 du bouchon 70 est filetée pour être engagée dans la sixième portion 21 taraudée complémentaire de l'alésage. De plus, il est prévu un alésage 73 traversant la paroi du bouchon tubu­laire 70. Cet alésage 73 est incliné par rapport à l'axe central du bouchon 70 vers les moyens de blocage 40 en direction de l'extérieur. L'alésage 73 est taraudé pour recevoir une vise de pression 75 qui vient reposer contre la rainure 20 formée au niveau de la cinquième portion 20 de l'alésage 11, pour immobiliser le bouchon à rotation et en translation dans l'alésage 11.The tubular plug 70 is formed by a thick-walled cylinder defining a through internal chamber 72. The external surface 71 of the plug 70 is threaded to be engaged in the sixth tapped portion 21 complementary to the bore. In addition, there is provided a bore 73 passing through the wall of the tubular plug 70. This bore 73 is inclined relative to the central axis of the plug 70 towards the locking means 40 in the direction of the outside. The bore 73 is tapped to receive a pressure target 75 which comes to rest against the groove 20 formed at the fifth portion 20 of the bore 11, to immobilize the plug in rotation and in translation in the bore 11.

Selon la représentation donnée sur la figure 1, l'organe de verrouillage 100 comprend une tige principale cylindrique 102. Cette tige 102 est munie à une première extrémité référencée 103 d'une tête évasée 104 en l'espèce en forme de calotte hémisphérique. La seconde extrémité référencée 105 de l'organe de verrouil­lage 100, destinée à être introduite dans l'alésage 11 du corps 10 se termine sous forme d'une pointe tronconique effilée 106.According to the representation given in FIG. 1, the locking member 100 comprises a main cylindrical rod 102. This rod 102 is provided at a first end referenced 103 with a flared head 104 in this case in the form of a hemispherical cap. The second end referenced 105 of the locking member 100, intended to be introduced into the bore 11 of the body 10 ends in the form of a tapered frustoconical point 106.

A proximité de cette extrémité, la tige cylindrique 102 est munie d'une rainure annulaire 108. Plus précisément, cette dernière présente une section en U à bords divergents vers l'extérieur. Plus précisément encore, la surface latérale de la rainure 108, la plus proche de la pointe 106, est inclinée sur l'axe de la tige 102 en rappro­chement de la pointe 106 vers l'extérieur.Near this end, the cylindrical rod 102 is provided with an annular groove 108. More precisely, the latter has a U-shaped section with diverging edges towards the outside. More precisely still, the lateral surface of the groove 108, the closest to the tip 106, is inclined on the axis of the rod 102 in approach of the tip 106 towards the outside.

Pour assembler la serrure mobile conforme à la présente invention ainsi composée, il convient de procéder comme suit.To assemble the movable lock according to the present invention thus composed, it is necessary to proceed as follows.

Le cylindre à rotor/stator 30 est inséré dans l'alésage 11 du corps 10 par la seconde extrémité 14 de celui-ci.The rotor / stator cylinder 30 is inserted into the bore 11 of the body 10 by the second end 14 thereof.

Le cylindre 30 est inséré dans la seconde portion complémentaire 16 du corps 10. Le stator 32 du cylindre 30 est ainsi immobilisé en rotation par rapport au corps 10.The cylinder 30 is inserted into the second complementary portion 16 of the body 10. The stator 32 of the cylinder 30 is thus immobilized in rotation relative to the body 10.

La pièce intermédiaire d'entraînement 50 est ensuite insérée dans l'alésage 11 du corps 10 par la seconde extrémité 14 de celui-ci. L'alésage 52 de la couronne 51 est engagé sur le prolongement 36 du rotor 34 pour être lié à rotation avec celui-ci. La découpe 53 est engagée sur le téton 37.The intermediate drive part 50 is then inserted into the bore 11 of the body 10 by the second end 14 thereof. The bore 52 of the crown 51 is engaged on the extension 36 of the rotor 34 to be linked in rotation with the latter. The cutout 53 is engaged on the stud 37.

Les deux demi-couronnes 42, 44 formant les moyens de blocage 40 sont alors introduites dans l'alésage 11 du corps 10, toujours par la seconde extré­mité 14 de celui-ci. Les deux demi-couronnes 42, 44 sont ainsi glissées dans la quatrième portion 19 en forme d'oval ou d'ellipse, respectivement de part et d'autre des tétons 55, 56 diamètralement opposés.The two half-rings 42, 44 forming the locking means 40 are then introduced into the bore 11 of the body 10, still by the second end 14 of the latter. The two half-rings 42, 44 are thus slid into the fourth portion 19 in the form of an oval or an ellipse, respectively on either side of the diametrically opposed studs 55, 56.

Enfin, le bouchon 70 est vissé dans la sixième portion 21 de l'alésage 11. Le bouchon est ensuite immobilisé dans l'alésage 11 grâce à une vis de pression 75 engagée dans le canal 73.Finally, the plug 70 is screwed into the sixth portion 21 of the bore 11. The plug is then immobilized in the bore 11 by means of a pressure screw 75 engaged in the channel 73.

On notera que l'épaisseur des demi-couronnes 42, 44 composant les moyens de blocage correspond sensible­ment,tout en étant légèrement inférieure, à la largeur de la quatrième portion 19. De plus, dans le cadre de la présente invention il est prévu une pluralité de paires de demi-couronnes 42, 44 dont les évidements centraux 45, 46 présentent des rayons différents, ainsi qu'une série de bouchons 70 dont la chambre cylindrique interne 72 présente également des rayons différents.It will be noted that the thickness of the half-rings 42, 44 making up the locking means corresponds substantially, while being slightly less, to the width of the fourth portion 19. In addition, in the context of the present invention there is provided a plurality of pairs of half-rings 42, 44 whose central recesses 45, 46 have different radii, as well as a series of plugs 70 whose internal cylindrical chamber 72 also has different radii.

Les demi-couronnes 42, 44 et le bouchon 70 insérés dans l'alésage 11 du corps 10 sont choisis de telle sorte que, d'une part, les deux éléments en forme générale de demi-couronne 42, 44 formant en position de travail (figure 2b) et au niveau de leur surface interne 45, 46 un logement dont la plus petite dimension trans­versale à l'axe 12 est inférieure au diamètre de la tige 102, mais supérieure à celui du fond de la rainure 108 pour retenir l'organe 100, tout en libérant en position de repos escamotée (figure 2a) un logement central dont la plus petite dimension transversale est supérieure au diamètre de la tige 102 et, d'autre part, que le bouchon 70 possède une chambre cylindrique interne trasversante 72 dont le rayon est complémentaire de celui de la tige cylindrique de l'organe de verrouillage 100.The half-rings 42, 44 and the plug 70 inserted in the bore 11 of the body 10 are chosen such that, on the one hand, the two elements in the general form of half-ring 42, 44 forming in the working position (Figure 2b) and at their internal surface 45, 46 a housing whose smallest transverse dimension to the axis 12 is less than the diameter of the rod 102, but greater than that of the bottom of the groove 108 to retain the member 100, while releasing in the retracted rest position (FIG. 2a) a central housing the smallest transverse dimension of which is greater than the diameter of the rod 102 and, on the other hand, that the plug 70 has an internal transverse cylindrical chamber 72 whose radius is complementary to that of the cylindrical rod of the locking member 100.

Le fonctionnement de la serrure mobile conforme à la présente invention est assuré comme suit.The operation of the movable lock according to the present invention is ensured as follows.

Pour introduire l'organe de verrouillage 100 dans l'alésage 11 du corps 10 il convient de placer les moyens de blocage 42, 44 en position de repos escamotéeTo introduce the locking member 100 into the bore 11 of the body 10, the locking means 42, 44 should be placed in the retracted rest position

Pour cela, les demi-couronnes 42, 44 doivent être repoussées contre les calottes hémicylindri­ques de la quatrième portion 19 de l'alésage 11. En d'autres termes, le rotor 34 du cylindre 30 doit être positionnée de telle sorte que les tétons 55, 56, de la pièce intermédiaire d'entraînement 50 soient disposés selon le petit axe de cette portion 19. Ainsi, les demi-­couronnes 42, 44 libèrent un passage cylindrique de rayon supérieur à celui de la tige cylindrique 102 de l'organe de verrouillage 100. L'extrémité 105 de l'organe de verrouillage 100 peut alors être introduite dans l'alé­sage 11 du corps 100 par la seconde extrémité 14 de celui-ci. La rainure annulaire 108 est placée en regard des demi-­ couronnes 42, 44. La partie 105 de l'organe de verrouillage 100 placée au-delà de cette rainure annulaire 108 pénètre dans l'alésage 52 de la pièce intermédiaire d'entraînement 50. L'épaisseur de cette pièce intermédiaire 50 considérée parallèlement à l'axe 12 doit être adaptée en conséquence. L'illustration de cette pièce donnée sur les figures est schématique , l'épaisseur de la pièce 50 étant avantageuse­ment égale à la somme de la longueur du prolongement 36 du rotor 34 et de l'extrémité 105 de l'organe de verrouillage 100 placée au-delà de la rainure annulaire 108.For this, the half-rings 42, 44 must be pushed against the semi-cylindrical caps of the fourth portion 19 of the bore 11. In other words, the rotor 34 of the cylinder 30 must be positioned so that the pins 55 , 56, of the intermediate drive part 50 are arranged along the minor axis of this portion 19. Thus, the half-rings 42, 44 release a cylindrical passage of radius greater than that of the cylindrical rod 102 of the member locking 100. The end 105 of the locking member 100 can then be introduced into the bore 11 of the body 100 by the second end 14 of the latter. The annular groove 108 is placed opposite the half crowns 42, 44. The part 105 of the locking member 100 placed beyond this annular groove 108 penetrates into the bore 52 of the intermediate drive part 50. The thickness of this intermediate part 50 considered parallel to axis 12 must be adapted accordingly. The illustration of this part given in the figures is schematic, the thickness of the part 50 being advantageously equal to the sum of the length of the extension 36 of the rotor 34 and the end 105 of the locking member 100 placed at the beyond the annular groove 108.

Pour verrouiller la serrure il suffit alors d'entraîner le rotor 34 en rotation sur 90° pour disposer les tétons 55, 56 de la pièce intermédiaire d'entraînement 50 selon le grand axe de la portion 19 de l'alésage 11.To lock the lock, it suffices to drive the rotor 34 in 90 ° rotation to arrange the pins 55, 56 of the intermediate drive part 50 along the major axis of the portion 19 of the bore 11.

Cette rotation du rotor 34 et de la pièce intermédiaire d'entraînement 50 induit un pivotement des demi-couronnes 42, 44 de la position de repos escamotée représentée sur la figure 2a à la position de travail re­présentée sur la figure 2b.This rotation of the rotor 34 and of the intermediate drive part 50 induces a pivoting of the half-rings 42, 44 from the retracted rest position shown in FIG. 2a to the working position shown in FIG. 2b.

Dans cette dernière position, la périphé­rie extérieure 47, 48 des demi-couronnes 42, 44 repose contre les pans parallèles 24, 25 de la portion 19 de l'alésage 11 selon des génératrices coïncidant avec le plan de coupe III-III. Les demi-couronnes 42, 44 délimi­tent ainsi par leur surface cylindrique 45, 46 un logement sensible, dont la plus petite dimension est sensiblement complémentaire du rétrécissement prévu sur l'organe de verrouillage 100 au niveau de la rainure 108. L'organe de verrouillage 100 est de ce fait immobilisé en translation sur le corps 10 de la serrure tout en restant libre de rotation autour de l'axe 12. De plus, le corps 10 ne peut être bloqué à rotation puisqu'il est symétrique de révolution autour de l'axe 12. Dans cette position de fermeture la serrure permet par exemple de relier dexu oeillets solidaires l'un d'un battant de porte, l'autre du dormant, engagés sur la tige 102 de l'organe de verrouillage 100 entre le corps 10 de la serrure et la tête évasée 104. Pour retirer l'organe de verrouillage 100, il suffit de faire pivoter le stator 34 en sens inverse pour repor­ter les couronnes de blocage 42, 44 en position escamo­tée comme représenté sur la figure 2a.In this latter position, the outer periphery 47, 48 of the half-rings 42, 44 rests against the parallel faces 24, 25 of the portion 19 of the bore 11 along generatrices coinciding with the cutting plane III-III. The half-rings 42, 44 thus delimit by their cylindrical surface 45, 46 a sensitive housing, the smallest dimension of which is substantially complementary to the narrowing provided on the locking member 100 at the level of the groove 108. The locking member 100 is therefore immobilized in translation on the body 10 of the lock while remaining free to rotate about the axis 12. In addition, the body 10 cannot be locked in rotation since it is symmetrical in revolution around the 'axis 12. In this closed position the lock allows for example to connect dexu integral eyelets one of a door leaf, the other of the frame, engaged on the rod 102 of the locking member 100 between the body 10 of the lock and the flared head 104. To remove the locking member 100, it suffices to rotate the stator 34 in the opposite direction to transfer the locking rings 42, 44 to the retracted position as shown in FIG. 2a.

On remarquera que lorsque l'organe de verrouillage 100 est introduit dans le corps 10 de la serrure la vis de pression 75 est inaccessible et de ce fait le retrait du bouchon 70 pour accéder aux moyens de blocage 40 est rendu impossible.It will be noted that when the locking member 100 is introduced into the body 10 of the lock, the pressure screw 75 is inaccessible and therefore the removal of the plug 70 to access the locking means 40 is made impossible.

Néanmoins, toute personne autorisée peut changer ou choisir le bouchon 70 et les moyens de blocage 40 en fonction du diamètre, de la longueur et de la forme de l'organe de verrouillage 100 utilisé.However, any authorized person can change or choose the plug 70 and the locking means 40 as a function of the diameter, the length and the shape of the locking member 100 used.

En effet, pour changer les moyens de blocage 40 il suffit après avoir retirée l'organe de verrouillage 100 et après avoir desserré la vis de pression 75, de retirer le bouchon 70.In fact, to change the locking means 40 it suffices after having removed the locking member 100 and after having loosened the pressure screw 75, to remove the plug 70.

Bien entendu la présente invention n'est pas limitée au mode de réalisation particulier qui vient d'être décrit mais s'étend à toutes variantes conformes à son esprit.Of course the present invention is not limited to the particular embodiment which has just been described but extends to all variants in accordance with its spirit.

Ainsi, par exemple on peut envisager d'utiliser une seule demi-couronne 42 ou 44 pour assurer le blocage de l'organge de verrouillage 100 dans le corps 10 de la serrure. De même, l'organe de verrouillage 100 illustré sur les figures n'est donné qu'à titre d'exemple non limitatif. On peut envisager d'utiliser des organes de verrouillage de formes différentes. La tête 104 évasée de forme hémisphérique peut par exemple être remplacée par un oeillet ou une tête aplatie.Thus, for example, it is conceivable to use a single half-crown 42 or 44 to block the locking member 100 in the body 10 of the lock. Similarly, the locking member 100 illustrated in the figures is given only by way of nonlimiting example. One can consider using locking members of different shapes. The flared head 104 of hemispherical shape can for example be replaced by an eyelet or a flattened head.

On notera que dans le cadre de la présente invention l'alésage 11 du corps et les différents éléments 30, 50, 40, 70 qu'il loge sont tous coaxiaux, cette caractéristique permet une fabrication simple et aisée du corps 10 muni d'un alésage 11 traversant. Cette carac­téristique permet également de réaliser un corps 10 robuste et parfaitement symétrique de révolution autour de l'axe 12 précité , ce qui interdit toute prise sur la surface extérieure du corps.It will be noted that in the context of the present invention the bore 11 of the body and the various elements 30, 50, 40, 70 which it houses are all coaxial, this characteristic allows a simple and easy manufacture of the body 10 provided with a bore 11 through. This characteristic also makes it possible to produce a robust and perfectly symmetrical body 10 of revolution about the aforementioned axis 12, which prohibits any grip on the external surface of the body.

On notera que l'extrémité tronconique 106 de l'organe de verrouillage 100 facilite l'écartement des couronnes de blocage 42, 44 lors de l'insertion de l'organe 100 dans le corps 10. Le cas échéant, il peut en être de même à l'aide des bords divergents de la rainure 108 lors du retrait de l'organe de verrouillage 100.Note that the frustoconical end 106 of the locking member 100 facilitates the spacing of the locking rings 42, 44 during the insertion of the member 100 in the body 10. If necessary, it may be even using the divergent edges of the groove 108 during the withdrawal of the locking member 100.

On va maintenant préciser un mode de réalisation particulier, non limitatif,des couronnes de blocage 42, 44 et de la portion 19 de l'alésage 11 précité recevant celles-ci, en regard des figures 6 et 7 annexées. La figure 6 qui représente une vue en coupe similaire à la figure 2a illustre les couronnes de blocage 42, 44 en position de repos escamotée dans la portion 19. La figure 7 qui représente une vue en coupe similaire à la figure 2b illustre les mêmes couronnes de blocage 42, 44 en position de travail dans la portion 19.We will now specify a particular, non-limiting embodiment of the locking rings 42, 44 and of the portion 19 of the aforementioned bore 11 receiving these, with reference to Figures 6 and 7 appended. Figure 6 which shows a sectional view similar to Figure 2a illustrates the locking rings 42, 44 in the retracted rest position in the portion 19. Figure 7 which shows a sectional view similar to Figure 2b illustrates the same crowns 42, 44 in the working position in the portion 19.

Sur les figures 6 et 7 on a représenté R₁ le rayon de la tige 102 de l'organe de blocage 100, R₂ le rayon du fond de la rainure annulaire 108, R₃ le rayon des surfaces internes 45, 46 des couronnes de blocage 42, 44, R₄ le rayon des surfaces externes 47, 48 de ces mêmes couronnes, A₁ le petit axe de la portion 19, c'est-à-dire la distance sépa­rant les pans 24, 25 parallèles et enfin A₂ le grand axe de la portion 19, c'est-à-dire la plus grande distance séparant les calottes hémicylindriques 22, 23.FIGS. 6 and 7 show R₁ the radius of the rod 102 of the locking member 100, R₂ the radius of the bottom of the annular groove 108, R₃ the radius of the internal surfaces 45, 46 of the locking rings 42, 44, R₄ the radius of the external surfaces 47, 48 of these same rings, A₁ the minor axis of the portion 19, that is to say the distance separating the sides 24, 25 parallel and finally A₂ the major axis of the portion 19, i.e. the longest distance separating the semi-cylindrical caps 22, 23.

Selon le mode de réalisation représenté sur les figures 6 et 7, le géométrie des couronnes de blocage 42, 44 et de la portion 19 de l'alésage 11 est adaptée, d'une part, pour obtenir un déplacement minimal des couronnes de blocage 42,44 entre la posi­tion de repos escamotée et la position de travail pour conserver une épaisseur maximale du corps 10, tout en garantissant un blocage certain de l'organe 100 en posi­tion de travail. De plus la géométrie des couronnes de blocage 42, 44 et de la portion 19 représentée sur les figures 6 et 7 est adaptée pour que en position de repos escamotée les moyens de blocage forment un logement in­terne d'enveloppe cylindrique complémentaire de l'envelop­pe de la tige cylindrique de l'organe de verrouillage.According to the embodiment shown in Figures 6 and 7, the geometry of the locking rings 42, 44 and of the portion 19 of the bore 11 is adapted, on the one hand, to obtain a minimum displacement of the locking rings 42 , 44 between the retracted rest position and the working position to maintain a maximum thickness of the body 10, while guaranteeing a certain blocking of the member 100 in the working position. In addition, the geometry of the locking rings 42, 44 and of the portion 19 shown in FIGS. 6 and 7 is adapted so that, in the retracted rest position, the locking means form an internal housing of a cylindrical envelope complementary to the envelope of the cylindrical rod of the locking member.

Le rayon R₃ des surfaces internes 45, 46 des couronnes de blocage est égal , au jeu près, au rayon externe R₁ de la tige 102.The radius R₃ of the internal surfaces 45, 46 of the locking rings is equal, apart from the clearance, to the external radius R₁ of the rod 102.

Le rayon R₄ des surfaces externes des couronnes de blocage est égal, au jeu près, au rayon des surfaces hémicylindriques 22, 23 de la portion 19 de l'alésage 11.The radius R₄ of the external surfaces of the locking rings is equal, apart from play, to the radius of the semi-cylindrical surfaces 22, 23 of the portion 19 of the bore 11.

Le décalage entre le centre des surfaces cylindriques internes 45, 46 et surfaces cylindriques externes 47, 48 est égal à la différence entre les rayons R₁ et R₂ précités.The offset between the center of the internal cylindrical surfaces 45, 46 and external cylindrical surfaces 47, 48 is equal to the difference between the above-mentioned radii R₁ and R₂.

Le petit axe A₁ de la portion 19 coïncidant avec le plan de coupe III-III (i.e. la distance entre les pans (24, 25) est égal, au jeu près, au double du rayon R₄ des surfaces externes 47, 48 des couronnes de blocage.The minor axis A₁ of the portion 19 coinciding with the section plane III-III (ie the distance between the sides (24, 25) is equal, apart from play, to twice the radius R₄ of the external surfaces 47, 48 of the crowns of blocking.

Enfin, la longueur des pans 24, 25 perpen­diculairement à l'axe 12 est égale au double de la dif­férence entre les rayons R₁ et R₂. En d'autres termes, le grand axe A₂ de la portion 19, coïncidant avec le plan de coupe V-V, est égal au double du rayon R₄ additionné du double de la différence entre les rayons R₁ et R₂, ou encore la différence entre le grand axe A₂ et le petit axe A₁ de la portion 19 de l'alésage est sensi­blement égale, au jeu près, au double de la différence entre le rayon R₁ de la tige cylindrique 102 de l'organe de verrouillage 100 et le rayon R₂ du fond de la rainure annulaire 108.Finally, the length of the panels 24, 25 perpendicular to the axis 12 is equal to twice the difference between the radii R₁ and R₂. In other words, the major axis A₂ of the portion 19, coinciding with the cutting plane VV, is equal to twice the radius R₄ added double the difference between the radii R₁ and R₂, or the difference between the major axis A₂ and the minor axis A₁ of the portion 19 of the bore is substantially equal, apart from play, to twice the difference between the radius R₁ of the cylindrical rod 102 of the locking member 100 and the radius R₂ of the bottom of the annular groove 108.

Selon le mode de réalisation représenté sur les figures 6 et 7, la surface extérieure 47, 48 des couronnes de blocage 42, 44 présente une ouverture angulaire inférieure à 180°.According to the embodiment shown in Figures 6 and 7, the outer surface 47, 48 of the locking rings 42, 44 has an angular opening of less than 180 °.

On a représenté sur les figures 8 et 9 une variante de réalisation des couronnes de blocage référencées respectivement 142, 144 et dont les surfaces cylindriques externes 147, 148 présentent une ouverture angulaire de 180°. Les surfaces cylindriques internes des couronnes de blocage 142, 144 sont référencées 145, 146 sur les figures 8 et 9. Ces figures représentent respectivement, de façon similaire aux figures 6 et 7, les organes de verrouillage en position de repos escamotée, d'une part, et en position de travail, d'autre part.There is shown in Figures 8 and 9 an alternative embodiment of the locking rings referenced respectively 142, 144 and whose external cylindrical surfaces 147, 148 have an angular opening of 180 °. The internal cylindrical surfaces of the locking rings 142, 144 are referenced 145, 146 in Figures 8 and 9. These figures respectively represent, similarly to Figures 6 and 7, the locking members in the retracted rest position, of a on the other hand, and in the working position.

Les rapports existant entre le rayon R₄ des surfaces externes cylindriques 147, 148, le rayon R₃ des surfaces internes cylindriques 145, 146, le décalage entre le centre de ces surfaces cylindriques, le rayon R₁ de la tige cylindrique de l'organe de verrouillage, le rayon R₂ du fond de la rainure annulaire 108, la lon­gueur des pans inclinés 24, 25, la longueur de petit axe A₁ et la longueur du grand axe A₂ restent similaires à ceux précédemment indiqués.The relationships existing between the radius R₄ of the cylindrical external surfaces 147, 148, the radius R₃ of the cylindrical internal surfaces 145, 146, the offset between the center of these cylindrical surfaces, the radius R₁ of the cylindrical rod of the locking member, the radius R₂ of the bottom of the annular groove 108, the length of the inclined faces 24, 25, the length of minor axis A₁ and the length of the major axis A₂ remain similar to those previously indicated.

Néanmoins, les ergots 55, 56 précités ne peuvent plus être intercalés entre les demi-couronnes de blocage. Il est donc prévu, dans chacune des couronnes de blocage 142, 144, les lumières oblongues ou boutonnières 141, 143 d'orientation radiale en regard de l'axe 12 de l'alésage 11. Les ouvertures oblongues 141, 143 sont destinées à recevoir des pions ou ergots simi­laires aux ergots 55, 56 précités, solidaires, en position excentrée, soit du stator 34 soit de la pièce intermédiaire d'entraînement 50 liée à rotation à celui-ci.However, the aforesaid lugs 55, 56 can no longer be interposed between the locking half-rings. It is therefore provided, in each of the locking rings 142, 144, the oblong or buttonholes 141, 143 of radial orientation opposite the axis 12 of the bore 11. The oblong openings 141, 143 are intended to receive pins or lugs similar to the lugs 55, 56 mentioned above, integral, in the eccentric position, either of stator 34 or of the intermediate drive part 50 linked in rotation to the latter.

Selon les variantes de réalisation qui viennent d'être décrites, les couronnes de blocage 42, 44, 142, 144 sont déplacées à pivotement entre la position de repos escamotée et la position de travail par le rotor 34 du cylindre ou la pièce intermédiaire de entraînement 50 liée en rotation à ce rotor.According to the embodiments which have just been described, the locking rings 42, 44, 142, 144 are pivotally moved between the retracted rest position and the working position by the rotor 34 of the cylinder or the intermediate drive part. 50 linked in rotation to this rotor.

On a illustré sur les figures 10 et 11 une variante de réalisation de la serrure mobile conforme à la présente invention dans laquelles les moyens de blocage sont adaptés pour être déplacés à translation dans l'alésage 11 entre la position de repos escamotée et la position de travail, dans une direction d'orientation radiale par rapport à l'axe 12 de l'alésage.Illustrated in Figures 10 and 11 an alternative embodiment of the movable lock according to the present invention in which the locking means are adapted to be moved in translation in the bore 11 between the retracted rest position and the position work, in a direction of radial orientation with respect to the axis 12 of the bore.

La portion 19 de l'alésage 11 est donc adaptée pour guider à translation les moyens de blocage.The portion 19 of the bore 11 is therefore adapted to guide the locking means in translation.

Selon la variante de réalisation représen­tée sur les figures 10 et 11 les moyens de blocage sont formés de deux structures en forme générale de demi-­couronnes, référencés 242, 244. Ces moyens de blocage 242, 244 présentent une surface interne 245, 246 en forme de calotte cylindrique dont le rayon correspond sensiblement au rayon externe de la tige 102 de l'organe de verrouillage 100. De préférence, la géométrie de la portion 19 est homologue de celle de la périphérie externe des moyens de blocage 242, 244. Selon l'illustration donnée sur les figures 10 et 11, la périphérie externe 247, 248 des moyens de blocage 242, 244 a la forme de calotte hémicylindrique. Par ailleurs, de préférence la longueur de la portion 19 considérée dans la direction de translation des moyens de blocage 242, 244 est adaptée pour déterminer une course de chacun des moyens de blocage 242, 244 dans cette direction de translation sensiblement égale à l'écart existant entre le rayon externe R₁ de la tige cylindrique de l'organe de verrouillage et le rayon R₂ du fond de la rainure annulaire 108. Le déplacement des moyens de blocage 242, 244 entre la position de repos escamotée et la position de travail et inversement peut être bote­nu à l'aide de pions excentrés, solidaires du rotor 34 ou d'une pièce intermédiaire d'entraînement 50 liée en rotation à celui-ci, engagés dans des lumières oblongues ou boutonnières 241, 243 réalisées dans les moyens de blocage 242, 244 selon une orientation générale trans­versale à la direction de translation de ces moyens de blocage.According to the variant embodiment shown in FIGS. 10 and 11, the locking means are formed by two structures in the general shape of half-crowns, referenced 242, 244. These locking means 242, 244 have an internal surface 245, 246 in the form cylindrical cap whose radius corresponds substantially to the external radius of the rod 102 of the locking member 100. Preferably, the geometry of the portion 19 is homologous with that of the external periphery of the locking means 242, 244. According to the 'illustration given in Figures 10 and 11, the outer periphery 247, 248 of the locking means 242, 244 has the shape of a semicylindrical cap. Otherwise, preferably the length of the portion 19 considered in the direction of translation of the locking means 242, 244 is adapted to determine a stroke of each of the locking means 242, 244 in this direction of translation substantially equal to the difference between the external radius R₁ of the cylindrical rod of the locking member and the radius R₂ of the bottom of the annular groove 108. The displacement of the locking means 242, 244 between the retracted rest position and the working position and vice versa can be botenu by means of eccentric pins, integral with the rotor 34 or with an intermediate drive part 50 linked in rotation thereto, engaged in oblong or buttonhole slots 241, 243 produced in the locking means 242, 244 according to a general orientation transverse to the direction of translation of these locking means.

La géométrie extérieure 247, 248 des moyens de blocage 242, 244 illustrée sur les figures 10 et 11 n'est donnée qu'à titre d'exemple non limitatif et peut être sujet à de nombreuses variantes de réalisation.The external geometry 247, 248 of the locking means 242, 244 illustrated in FIGS. 10 and 11 is given only by way of nonlimiting example and can be subject to numerous variant embodiments.

Le cas échéant, les moyens de blocage 242, 244 déplacés en translation peuvent être sollicités élasti­quement vers la position de travail représentée sur la figure 11, par exemple par des ressorts 250 intercalés entre le fond de la portion 19 de l'alésage 11, et la surface externe 247, 248 des moyens de blocage 242 ,244 comme illus­tré schématiquement sur la figure 11. Sur cette figure 11 les ressorts 250 représentés sont des ressorts héilcoïdaux, des ressorts 250 à lamelle pourraient être utilisés. De plus, lorsque les moyens de blocage 242, 244 sont ainsi sollicités élastiquement vers la position de travail, il est avantageusement prévu dans ceux-ci une découpe supplé­mentaire 251, s'étendant dans la direction de translation et et qui débouche dans les lumières oblongues ou bouton­nières 241, 243. Les découpes 251 s'étendent à partir des boutonnières 241, 243 vers l'intérieur de l'alésage 11, c'est-à-dire vers le petit axe de la portion 19. Les découpes 251 débouchent plus précisément dans la partie la plus extérieure des boutonnières 241, 243, c'est-à-­dire la partie de celles-ci qui reçoit les pions d'entraî­nement excentrés solidaires du rotor 34 ou de la pièce d'entraînement intermédiaire 50 liée à rotation à celui-ci, lorsque le cylindre 30 est en position de fermeture. Sur les figures 10 et 11 les découpes 251 sont représentées en traits interrompus. On obtient dans un tel cas une serrure mobile à fermeture automatique.Where appropriate, the locking means 242, 244 moved in translation can be resiliently biased towards the working position shown in FIG. 11, for example by springs 250 interposed between the bottom of the portion 19 of the bore 11, and the external surface 247, 248 of the locking means 242, 244 as illustrated diagrammatically in FIG. 11. In this FIG. 11 the springs 250 shown are helical springs, springs 250 with lamella could be used. In addition, when the locking means 242, 244 are thus urged elastically towards the working position, there is advantageously provided in these an additional cutout 251, extending in the direction of translation and and which opens into the oblong or buttonholes 241, 243. The cutouts 251 extend from the buttonholes 241, 243 towards the inside of the bore 11, that is to say towards the minor axis of the portion 19. The cutouts 251 open more precisely into the outermost part of the buttonholes 241, 243, that is to say the part of the latter which receives the eccentric drive pins integral with the rotor 34 or the part d 'intermediate drive 50 linked to rotation thereof, when the cylinder 30 is in the closed position. In FIGS. 10 and 11, the cutouts 251 are shown in broken lines. In such a case, a mobile lock with automatic closure is obtained.

En effet, lorsque le cylindre 30 est en position de fermeture, les moyens de blocage 242, 244 sont placés dans la position de travail représentée sur la figure 11 grâce à la sollicitation élastique des ressorts 250. Les pions d'entraînement excentrés solidaires du rotor 34 ou de la pièce d'entraînement intermédiaire liée à rotation à celui-ci sont placés dans la partie la plus extérieure des boutonnières 241, 243, en regard des découpes 251. Lorsque un organe de verrouillage 100 est introduit dans la serrure, l'extrémité effilée, tronconique 106 de cet organe écarte les moyens de blocage 242, 244 à l'encontre de la sollicitation élastique. Les pions d'en­traînement extcentrés précités se déplaçant dans les découpes 251. Lorsque la rainure annulaire 108 arrive en regard des moyens de blocage 242, 244, ceux-ci sont repous­sés élastiquement dans la rainure 108, les pions d'entraîne­ment excentrés revenant dans les boutonnières 241, 243. Enfin pour ouvrir la serrure et retirer l'organe de blocage 100, il suffit de tourner le cylindre 30. Les pions d'entraî­nement excentrés solidaires du rotor 34 ou de la pièce intermédiaire 50 se déplacent dans les boutonnières 241, 243 vers le grand axe de la portion 19 et écartent les moyens de blocage 242, 244.In fact, when the cylinder 30 is in the closed position, the locking means 242, 244 are placed in the working position shown in FIG. 11 thanks to the elastic stress of the springs 250. The eccentric drive pins integral with the rotor 34 or the intermediate drive part linked to rotation therewith are placed in the outermost part of the buttonholes 241, 243, facing the cutouts 251. When a locking member 100 is introduced into the lock, the tapered, frustoconical end 106 of this member separates the locking means 242, 244 against the elastic stress. The aforementioned eccentric drive pins moving in the cutouts 251. When the annular groove 108 comes opposite the locking means 242, 244, these are pushed elastically into the groove 108, the eccentric drive pins returning in the buttonholes 241, 243. Finally to open the lock and remove the locking member 100, it suffices to turn the cylinder 30. The eccentric drive pins integral with the rotor 34 or with the intermediate piece 50 move in the buttonholes 241, 243 towards the major axis of the portion 19 and move away the locking means 242, 244.

Comme indiqué précédemment la présente invention n'est pas limitée aux modes de réalisation particuliers qui viennent d'être décrits mais s'étend à toutes variantes conformes à son esprit.As indicated previously, the present invention is not limited to the particular embodiments which have just been described but extends to all variants in accordance with its spirit.
