De telles serrures sont par exemple enseignées par le document US2603081 et CH596416 .Such locks are for example taught by the document US2603081 and CH596416 .

Dans certaine serrure, chaque paillette est constituée d'une paire de demi-paillettes (75,76) adjacentes et aptes à se déplacer chacune à l'encontre d'un moyen de rappel (9), à savoir pour une paire de demi-paillettes adjacentes (75,76) se déplaçant dans un même passage :

  • une première demi-paillette (75) s'étendant dans un premier plan perpendiculaire à l'axe longitudinal (A) du rotor (3), et se déplaçant au moins partiellement dans un premier passage ouvert (81) du rotor (3), et
  • une deuxième demi-paillette (76) s'étendant dans un deuxième plan correspondant audit premier plan.
In certain locks, each spangle consists of a pair of adjacent half-spangles (75,76) each capable of moving against a return means (9), namely for a pair of half-spangles (75, 76). adjacent sequins (75,76) moving in the same passage:
  • a first half-straw (75) extending in a first plane perpendicular to the longitudinal axis (A) of the rotor (3), and moving at least partially in a first open passage (81) of the rotor (3), and
  • a second half-spangle (76) extending in a second plane corresponding to said first plane.

De telles serrures sont connues et ont été commercialisées dans le passé. Une telle serrure est ainsi enseignée dans US 2155734 , DE2420847 .Such locks are known and have been marketed in the past. Such a lock is thus taught in US 2155734 , DE2420847 .

Par le document CH-264237 , on connaît une serrure de ce type, dans laquelle, ladite deuxième demi-paillette d'une paire de demi-paillettes se déplace au moins partiellement dans un deuxième passage ouvert du rotor distinct du premier passage ouvert pour la première demi-pailette de la paire considérée, tel que pour une série de paillettes comprenant chacune une paire de demi-paillettes, au moins une série de premières demi-paillettes ou une série de deuxièmes demi-paillettes coopèrent avec une goupille longitudinale.By document CH-264237 , a lock of this type is known, in which said second half-spangle of a pair of half-spangles moves at least partially in a second open passage of the rotor distinct from the first passage open for the first half-pail of the pair considered, such as for a series of sequins each comprising a pair of half-sequins, at least one series of first half-sequins or a series of second half-sequins cooperate with a longitudinal pin.

Cette serrure comporte un rotor présentant une fente longitudinale pour l'introduction d'une partie d'une clef de commande de paillettes logées dans des passages ouverts communiquant avec la fente longitudinale, ladite clef présentant un ou des canaux ou crans pour recevoir/guider, pour une série de paillettes, un nez de la paillette considérée pour la déplacer à l'encontre d'un moyen de rappel au moins entre une position verrouillée pour laquelle la paillette considérée s'étend au moins partiellement hors du volume du passage ouvert et partiellement dans un logement de verrouillage du stator, et une position déverrouillée pour laquelle la paillette considérée s'étend essentiellement dans le volume d'un passage ouvert du rotor,
dans lequel, pour certaines des paillettes, la paillette est constituée d'une paire de demi-paillettes adjacentes et aptes à se déplacer chacune à l'encontre d'un moyen de rappel, à savoir pour une paire de demi-paillettes adjacentes :

  • une première demi-paillette s'étendant dans un premier plan perpendiculaire à l'axe longitudinal du rotor, et se déplaçant au moins partiellement dans un premier passage ouvert du rotor, et
  • une deuxième demi-paillette s'étendant dans un deuxième plan correspondant audit premier plan, et se déplaçant au moins partiellement dans un deuxième passage ouvert du rotor distinct du premier passage ouvert pour la première demi-paillette de la paire considérée,
telle que pour une série de paillettes comprenant chacune une paire de demi-paillettes, au moins une série de premières demi-paillettes ou une série de deuxièmes demi-paillettes coopèrent avec une goupille longitudinale.This lock comprises a rotor having a longitudinal slot for the introduction of a part of a sequins control key housed in open passages communicating with the longitudinal slot, said key having one or more channels or notches for receiving / guiding, for a series of straws, a nose of the considered straw to move it against a return means at least between a locked position for which the considered straw extends at least partially outside the volume of the open passage and partially in a stator locking housing, and an unlocked position for which the straw considered extends essentially in the volume of an open passage of the rotor,
in which, for some of the sequins, the straw consists of a pair of adjacent half-sequins and each capable of moving against a return means, namely for a pair of adjacent half-sequins:
  • a first half-spangle extending in a first plane perpendicular to the longitudinal axis of the rotor, and moving at least partially in a first open passage of the rotor, and
  • a second half-straw extending in a second plane corresponding to said first plane, and moving at least partially in a second open passage of the rotor distinct from the first passage open for the first half-straw of the pair considered,
such as for a series of sequins each comprising a pair of half-sequins, at least one series of first half-sequins or a series of second half-sequins cooperate with a longitudinal pin.

De telles serrures sont difficiles à assembler et ont souvent fait l'objet de tentatives d'effraction avec des forêts. La destruction de paillettes constituées de deux demi-paillettes s'est avérée plus facile que des paillettes mono pièces.Such locks are difficult to assemble and have often been the subject of attempted break-ins with forests. The destruction of flakes consisting of two half-flakes has proven to be easier than single-piece flakes.

L'invention a pour objet des serrures du type selon le premier paragraphe du présent mémoire qui sont faciles à assembler et qui améliorent la résistance à l'effraction.The invention relates to locks of the type according to the first paragraph of this specification which are easy to assemble and which improve the resistance to burglary.

Le rotor et la serrure selon l'invention tels que revendiqués sont essentiellement caractérisés :
en ce que la goupille longitudinale (100) s'étend dans un canal longitudinal (110) du rotor traversant des passages ouverts (81,8) de la série de premières ou deuxièmes demi-paillettes (75,76) considérées pour limiter et guider le déplacement desdites demi-paillettes dans une partie de leur passage ouvert.The rotor and the lock according to the invention as claimed are essentially characterized:
in that the longitudinal pin (100) extends in a longitudinal channel (110) of the rotor passing through open passages (81,8) of the series of first or second half-flakes (75,76) considered to limit and guide the movement of said half-flakes in a part of their open passage.

De telles demi-paillettes opèrent ainsi comme des paillettes indépendantes. La ou les goupilles longitudinales servent de guides aux demi-paillettes et de butées, empêchant des mouvements lors de tentatives d'ouverture en n'utilisant pas la clef adéquate. De plus, en cas d'effraction avec un forêt dans la fente longitudinale du rotor, la ou les tiges longitudinales sont toujours actives pour s'opposer à des mouvements de demi-paillettes ou en cas d'endommagement d'une ou de tiges longitudinales, celle ou celles-ci peuvent se tordre empêchant alors tout mouvement de demi-paillettes. On a également observé que la ou les goupilles permettaient de servir de moyen antivibration lors d'une tentative d'effraction par un forêt.Such half-flakes thus operate as independent flakes. The longitudinal pin or pins serve as guides for the half-straws and as stops, preventing movements during opening attempts by not using the appropriate key. In addition, in the event of a break-in with a forest in the longitudinal slot of the rotor, the longitudinal rod (s) are always active to oppose movements of half-flakes or in the event of damage to one or more longitudinal rods. , that or these can twist preventing any movement of the half-sequins. It was also observed that the pin (s) made it possible to serve as an anti-vibration means during an attempted break-in through a forest.

L'invention permet selon des formes de réalisation d'obtenir les propriétés suivantes :

  • un grand nombre de paillettes indépendantes, par exemple 10 fois ou plus de 10 fois de paires de demi-paillettes indépendantes
  • une deux ou plus de deux tiges longitudinales de sertissage pour retenir les paillettes ou demi-paillettes
  • une ou plus, par exemple 2 ou 3 plaquettes anti-forage à l'avant du barillet
  • plusieurs logements indépendants pour des extrémités de paillettes dans le stator, par exemple 4 logements indépendants d'extrémité de demi-paillettes dans le stator.
  • utilisation d'une clef crantée ou avec canal, par exemple avec des pistes indépendantes, par exemple 2, 4 ou plus de 4.
  • un nombre important de combinaisons.
  • un niveau de sécurité améliorée, pas d'entrouverture
  • une meilleure tenue au couple de forçage
  • une résistance accrue au crochetage
  • une résistance au forage
According to embodiments of the invention, the following properties can be obtained:
  • a large number of independent spangles, for example 10 times or more than 10 times of pairs of independent half spangles
  • one two or more longitudinal crimping rods to retain the sequins or half-sequins
  • one or more, for example 2 or 3 anti-drilling pads at the front of the barrel

Le rotor (3) présente une fente longitudinale (4) pour l'introduction d'une partie (5) (par exemple plate avec un profil définissant une série de crans pour actionner/fuider le mouvement de paillettes lors de l'introduction de la partie 5 dans la fente longitudinale) d'une clef de commande (6) de paillettes (7) logées dans des passages ouverts (8) communiquant avec la fente longitudinale (4), ladite clef (6) présentant un ou des canaux ou crans (60) pour recevoir/guider, pour une série de paillettes, un nez (70) de la paillette (7) considérée pour la déplacer à l'encontre d'un moyen de rappel (9) (un ressort) au moins entre une position verrouillée pour laquelle la paillette considérée (7) s'étend au moins partiellement hors du volume du passage ouvert (8) et partiellement dans un logement de verrouillage du stator (1) (une partie extrême de la paillette se trouvant dans un logement du stator pour s'opposer à une rotation du rotor par rapport à son stator), et une position déverrouillée pour laquelle la paillette considérée (7) s'étend essentiellement dans le volume d'un passage ouvert (8) du rotor (3) (lorsque toutes les paillettes se trouvent en position déverrouillée, une rotation du rotor est possible).The rotor (3) has a longitudinal slot (4) for the introduction of a part (5) (for example flat with a profile defining a series of notches to actuate / guide the movement of straws during the introduction of the part 5 in the longitudinal slot) of a control key (6) of flakes (7) housed in open passages (8) communicating with the longitudinal slot (4), said key (6) having one or more channels or notches (60 ) for receiving / guiding, for a series of straws, a nose (70) of the straw (7) considered to move it against a return means (9) (a spring) at least between a locked position for which the straw in question (7) extends at least partially outside the volume of the open passage (8) and partially in a locking housing of the stator (1) (an end part of the straw being in a housing of the stator for oppose a rotation of the rotor relative to its stator), and an unlocked position for which the considered straw (7) extends essentially in the volume of an open passage (8) of the rotor (3) (when all the straws are in the unlocked position, a rotation of the rotor is possible).

Pour certaines des paillettes (7), la paillette est constituée d'une paire de demi-paillettes (75,76) adjacentes et aptes à se déplacer chacune à l'encontre d'un moyen de rappel (9), à savoir pour une paire de demi-paillettes adjacentes (75,76) :

  • une première demi-paillette (75) s'étendant dans un premier plan perpendiculaire à l'axe longitudinal (A) du rotor (3), et se déplaçant au moins partiellement dans un premier passage ouvert (81) du rotor (3), et
  • une deuxième demi-paillette (76) s'étendant dans un deuxième plan correspondant audit premier plan, et se déplaçant au moins partiellement dans un deuxième passage ouvert (8) du rotor (3) distinct du premier passage ouvert (81) pour la première demi-paillette (75) de la paire considérée.
For some of the straws (7), the straw consists of a pair of adjacent half-straws (75,76) each capable of moving against a return means (9), namely for a pair of adjacent half-sequins (75,76):
  • a first half-straw (75) extending in a first plane perpendicular to the longitudinal axis (A) of the rotor (3), and moving at least partially in a first open passage (81) of the rotor (3), and
  • a second half-spangle (76) extending in a second plane corresponding to said first plane, and moving at least partially in a second open passage (8) of the rotor (3) separate from the first open passage (81) for the first half-spangle (75) of the pair considered.

Pour une série de paillettes (7) comprenant chacune une paire de demi-paillettes (75,76), au moins une série de premières demi-paillettes (75) ou une série de deuxièmes demi-paillettes (76) coopèrent avec une goupille longitudinale (100) s'étendant dans un canal longitudinal (110) du rotor traversant des passages ouverts (81,8) de la série de premières ou deuxièmes demi-paillettes (75,76) considérées pour limiter et guider le déplacement desdites demi-paillettes dans une partie de leur passage ouvert.For a series of sequins (7) each comprising a pair of half-sequins (75,76), at least one series of first half-sequins (75) or a series of second half-sequins (76) cooperate with a longitudinal pin (100) extending in a longitudinal channel (110) of the rotor passing through open passages (81,8) of the series of first or second half-flakes (75,76) considered to limit and guide the movement of said half-flakes in a part of their open passage.

Dans le cas représenté, les demi-paillettes de la première série de demi-paillettes (75) et les demi-paillettes de la deuxième série de demi-paillettes (76) coopèrent chacune respectivement avec une goupille longitudinale (100, 101) s'étendant dans un canal longitudinal (110,111) du rotor (3) traversant des passages ouverts (81,8)In the case shown, the half-flakes of the first series of half-flakes (75) and the half-flakes of the second series of half-flakes (76) each cooperate respectively with a longitudinal pin (100, 101) s' extending into a longitudinal channel (110,111) of the rotor (3) passing through open passages (81,8)

Pour chacune des demi-paillettes coopérant avec une goupille longitudinale (100, 101), la demi-paillette (75) considérée se déplace dans un passage ouvert (8,81) en communication avec la fente longitudinale (4) du rotor. Les passages 8,81 sont reliés entre eux par la fente longitudinale 4.For each of the half-straws cooperating with a longitudinal pin (100, 101), the half-straw (75) considered moves in an open passage (8,81) in communication with the longitudinal slot (4) of the rotor. The passages 8.81 are interconnected by the longitudinal slot 4.

Lesdits passages ouverts 8,81 présentent chacun (a) une première partie (810) définie entre deux faces planes (811,812) opposées et perpendiculaires à l'axe (A) du rotor (3), lesdites deux faces opposées (811,812) étant séparées l'une de l'autre par un premier bord (813) et un deuxième bord (814) opposé audit premier bord (813), (b) une deuxième partie (815) distante de la première partie, et (c) une partie intermédiaire (816) située entre lesdites première et deuxième parties (810,815).Said open passages 8,81 each have (a) a first part (810) defined between two flat faces (811,812) opposite and perpendicular to the axis (A) of the rotor (3), said two opposite faces (811,812) being separated one from the other by a first edge (813) and a second edge (814) opposite said first edge (813), (b) a second part (815) distant from the first part, and (c) a part intermediate (816) located between said first and second parts (810,815).

Les passages ouverts 8,81 sont séparés l'un de l'autre par une portion du rotor 3.The open passages 8,81 are separated from each other by a portion of the rotor 3.

Une tige longitudinale 100, 101 s'étend à travers la première partie d'un passage ouvert pour une demi-paillette.A longitudinal rod 100, 101 extends through the first part of an open passage for a half-straw.

Ces tiges longitudinales forment un renfort entre les demi-paillettes, rendant ainsi plus difficiles une effraction, et accroissant la résistance à une rotation avec un outil non approprié.These longitudinal rods form a reinforcement between the half-flakes, thus making it more difficult to break in, and increase the resistance to rotation with an inappropriate tool.

Chaque demi-paillette considérée (75, 76) est une pièce plate comportant (a) une première portion (750) s'étendant au moins partiellement dans la première partie (810) du passage ouvert (81), (b) une deuxième portion (751) s'étendant au moins partiellement dans la deuxième partie (815) du passage ouvert, et (c) une portion intermédiaire (752) s'étendant entre lesdites première et deuxième portions (750,751). La première portion (750) présente un premier élément (protubérance) ou bord (800) adapté pour glisser le long du premier bord (814) de la première partie (810) du passage ouvert (81) lors d'un mouvement de la demi-paillette (75,76); et un deuxième bord (801) présentant (*) une section ou partie (801) éloignée du deuxième bord (813) de la première partie (810) du passage ouvert (75) de manière à ne pas glisser le long du deuxième bord (813) de la première partie (810) du passage ouvert lors d'un déplacement de la demi-paillette considérée, et (*) une protubérance (802) portée par ladite section éloignée, ladite protubérance (802) étant avantageusement adaptée pour être adjacente, voire glisser le long du deuxième bord (813) de la première partie (810) du passage ouvert (81) lors d'un déplacement de ladite demi-paillette (75,76).Each considered half-straw (75, 76) is a flat part comprising (a) a first portion (750) extending at least partially in the first part (810) of the open passage (81), (b) a second portion (751) extending at least partially in the second portion (815) of the open passage, and (c) an intermediate portion (752) extending between said first and second portions (750,751). The first portion (750) has a first element (protrusion) or edge (800) adapted to slide along the first edge (814) of the first part (810) of the open passage (81) during movement of the half. -paillette (75.76); and a second edge (801) having (*) a section or part (801) remote from the second edge (813) of the first part (810) of the open passage (75) so as not to slide along the second edge ( 813) of the first part (810) of the passage open during a movement of the considered half-straw, and (*) a protuberance (802) carried by said remote section, said protuberance (802) being advantageously adapted to be adjacent , or even slide along the second edge (813) of the first part (810) of the open passage (81) during a displacement of said half-straw (75, 76).

La goupille (100,101) sert de moyen d'appui à la section éloignée (801) du deuxième bord (801) de la première portion (750) pour guider le mouvement de ladite première portion (750) lors d'un déplacement de la demi-paillette, et de moyen de butée pour ladite protubérance (802) pour limiter le déplacement de ladite première portion (801) lors d'un déplacement de la demi-paillette (75).The pin (100,101) serves as a support means for the section remote (801) from the second edge (801) of the first portion (750) to guide the movement of said first portion (750) during a displacement of the half. -paillette, and stop means for said protuberance (802) to limit the movement of said first portion (801) during a movement of the half-straw (75).

La demi-paillette considérée (75, 76) présente un nez (70) coopérant avec la clef pour actionner le déplacement de la demi-paillette. La goupille (100,101) sert de moyen de butée pour ledit nez (70) limiter le déplacement de ladite première portion (750) lors d'un déplacement de la demi-paillette (75,76).The considered half-straw (75, 76) has a nose (70) cooperating with the key to actuate the displacement of the half-straw. The pin (100,101) serves as a stop means for said nose (70) to limit the movement of said first portion (750) during a movement of the half-straw (75,76).

Chaque demi-paillette présente également une protubérance 700 seravnt d'appui à un ressort destiné à ramener la demi-paillette dans une position de verrouillage. La surface latérale 800 de cette protubérance peut être la surface glissant le long de la première face latérale 814 de la première partie du passage ouvert.Each half-straw also has a protuberance 700 supporting a spring intended to bring the half-straw into a locking position. The side surface 800 of this protuberance may be the surface sliding along the first side face 814 of the first part of the open passage.

La première goupille longitudinale (100) et la deuxième goupille longitudinale (101) sont diamétralement opposées par rapport à la fente longitudinale ou à l'axe (A) du rotor (3).The first longitudinal pin (100) and the second longitudinal pin (101) are diametrically opposed with respect to the longitudinal slot or to the axis (A) of the rotor (3).

Les figures 2A et 2B montrent en coupe le rotor 3 dans la chambre 2 du stator 1.The figures 2A and 2B show in section the rotor 3 in the chamber 2 of the stator 1.

A la figure 2A, la tige longitudinale 101 est engagée dans le canal 111. L'extrémité avant du canal 111 est protégée par une demi-plaquette 200 de haute dureté. A la figure 2B on apperçoit la tige longitudinale 100 s'étendant dans le canal 110 parallèle à l'axe A du rotor 3.To the figure 2A , the longitudinal rod 101 is engaged in the channel 111. The front end of the channel 111 is protected by a half-plate 200 of high hardness. To the figure 2B the longitudinal rod 100 can be seen extending in the channel 110 parallel to the axis A of the rotor 3.

La figure 5 est vue en coupe transversale du rotor 3 en position verrouillée, vue avant, sans le cache extérieur. Comme on le voit des extrémités de demi-paillettes s'étendent sous l'action des ressorts dans des logements distincts 210,211,212,213 du stator 1, ce qui permet de multiplier les moyens de résistance à un déverrouillage non approprié.The figure 5 is a cross-sectional view of the rotor 3 in the locked position, front view, without the outer cover. As can be seen, the ends of the half-flakes extend under the action of the springs in separate housings 210,211,212,213 of the stator 1, which makes it possible to multiply the means of resistance to inappropriate unlocking.

Il faut en effet utiliser une clef permettant de déplacer tous les nez 70 de manière appropriée pour que toutes les demi-paillettes s'étendent dans le volume cylindrique du rotor 3.It is indeed necessary to use a key making it possible to move all the noses 70 in an appropriate manner so that all the half-flakes extend into the cylindrical volume of the rotor 3.

Les figures 6A et 6B sont respectivement une vue d'une paire de demi-paillettes en position verouillée. Les figures 6C et 6D sont des vues similaires mais en position déverrouillée.The figures 6A and 6B are respectively a view of a pair of half-sequins in the locked position. The figures 6C and 6D are similar views but in the unlocked position.

Les figures 13A et B sont des vues d'une clef avec des crans guidant le déplacement des nez 70 des demi-paillettes.The figures 13A and B are views of a key with notches guiding the movement of the noses 70 of the half-flakes.

La figure 14 est vue des demi-plaquettes 200 de haute dureté protégant la partie avant des canaux 110 et 111. Les demi-plaquettes servent également de moyens de butée pour emêcher les tiges longitudinales de sortir une fois insérées par pression dans le rotor avantageusement muni des demi-paillettes.The figure 14 is seen of the high hardness half-plates 200 protecting the front part of the channels 110 and 111. The half-plates also serve as stop means to prevent the longitudinal rods from coming out once inserted by pressure into the rotor, advantageously provided with the half-plates. glitter.

La figure 17 est une vue similaire à celle de la figure 5 après une rotation du rotor d'environ 45°. Comme on le voit dans cette position le rotor revient dans une position verrouillée partielle, en l'absence de la clef adéquate. En cas de fermeture non adéquate de la serrure, une rotation avec un outil non approprié du rotor l'amenera à nouveau dans une position verrouillée.The figure 17 is a view similar to that of the figure 5 after a rotation of the rotor of approximately 45 °. As can be seen in this position, the rotor returns to a partially locked position, in the absence of the adequate key. If the lock is not properly closed, rotating the rotor with an inappropriate tool will bring it back to a locked position.
