Abstract

The lock has a pivoting latch (13) which blocks the bolt (3) in the lock's closed position. The latch rests on the tumbler (7) in the lock's closed position. The latch executes a complete pivoting turn after the tumbler has dropped completely and following the removal of the cylinder (19) so as to block the lock in its locked position. The tumbler incorporates an element (11) in a U-shaped cut-out section in the cover or case (2) of the lock.

Description

L'invention est relative à une serrure à pêne coulissant à sécurité améliorée.The invention relates to a sliding bolt lock with improved security.

Les serrures à pêne coulissant de ce type comportent une gorge déplaçable en translation perpendiculairement au sens de coulissement du pêne, à l'encontre d'un ressort de compression, de manière à effectuer un déplacement dans lequel l'extrémité supérieure de la gorge contourne une butée solidaire du coffre de la serrure.Sliding bolt locks of this type have a movable groove in translation perpendicular to the direction of sliding of the bolt, against a compression spring, so as to effect a displacement in which the upper end of the groove bypasses a stop integral with the trunk of the lock.

La gorge comporte un organe coopérant avec la butée solidaire du coffre de la serrure.The groove comprises a member cooperating with the stop integral with the trunk of the lock.

Cette butée solidaire du coffre présente une résistance et une section limitées, ce qui constitue un risque d'effraction lors d'une poussée importante sur le pêne dans le sens correspondant au coulissement rentrant du pêne dans la serrure.This stop integral with the trunk has a limited resistance and section, which constitutes a risk of break-in during a significant push on the bolt in the direction corresponding to the sliding return of the bolt in the lock.

Pour remédier à cet inconvénient, le brevet français 93.01023 publié sous le numéro FR 2.701.055 prévoit de renforcer la sécurité, en ajoutant à la serrure un verrou pivotant autour d'un axe du coffre.To remedy this drawback, French patent 93.01023 published under the FR number 2.701.055 plans to strengthen security by adding a lock to the lock lock pivoting around an axis of the trunk.

Ce verrou présente une conformation qui repose sur le pêne dans la position ouverte de la serrure et est en arc-boutement derrière le pêne dans la position fermée de la serrure, de manière à s'opposer au mouvement rentrant du pêne.This lock has a conformation which rests on the bolt in the position open from the lock and is braced behind the latch in the closed position of the lock, so as to oppose the return movement of the bolt.

Ce verrou glisse sur l'épaisseur du pêne lorsqu'on effectue le mouvement de verrouillage de la serrure et retombe par gravité derrière un décrochement du pêne après verrouillage de la serrure. Ce verrou est ensuite soulevé par la gorge lors du déverrouillage de la serrure, de manière à permettre le recul du pêne.This lock slides on the thickness of the bolt when the movement of lock lock and falls by gravity behind a latching hook after locking the lock. This lock is then lifted by the groove when unlocking of the lock, so as to allow the bolt to retract.

Ce dispositif donne entièrement satisfaction pour éviter tout risque d'effraction lors d'une poussée importante sur le pêne dans le sens correspondant au coulissement rentrant du pêne.This device is entirely satisfactory to avoid any risk break-in during a significant push on the bolt in the direction corresponding to the sliding return of the bolt.

Cependant, en cas de rupture du barillet de manoeuvre de la serrure, et après enlèvement de celui-ci, il existe un risque de soulèvement de la gorge, et du verrou en arc-boutement derrière le pêne, par un outil introduit dans le passage du barillet. However, in the event of the lock operating cylinder breaking, and after removal of it, there is a risk of lifting the throat, and the lock braced behind the bolt, by a tool inserted in the passage of the barrel.

L'invention a pour but d'améliorer la sécurité des serrures à pêne coulissant, en créant une nouvelle serrure simple et de dimensions comparables à celle de l'art antérieur, et en évitant une effraction par passage dans le trou de barillet.The object of the invention is to improve the security of sliding bolt locks, by creating a new simple lock with dimensions comparable to that of art anterior, and avoiding a break-in by passing through the barrel hole.

L'invention sera mieux comprise grâce à la description qui va suivre donnée à titre d'exemple non limitatif au regard des dessins annexés dans lesquels :

  • La figure 1 représente schématiquement une vue en perspective éclatée d'une serrure selon l'invention.
  • Les figures 2 à 5 représentent schématiquement le fonctionnement d'une serrure selon l'invention, dont le couvercle est non représenté.
The invention will be better understood thanks to the description which follows given by way of nonlimiting example with regard to the appended drawings in which:
  • Figure 1 schematically shows an exploded perspective view of a lock according to the invention.
  • Figures 2 to 5 schematically show the operation of a lock according to the invention, the cover is not shown.

En référence à la figure 1, une serrure 1 selon l'invention est entraínée par un organe de manoeuvre tel qu'un barillet, non représenté, et comporte un coffre 2 fermé par un couvercle 2a. Le coffre 2 de la serrure selon l'invention contient un pêne 3 coulissantReferring to Figure 1, a lock 1 according to the invention is driven by a operating member such as a barrel, not shown, and comprises a closed trunk 2 by a cover 2a. The safe 2 of the lock according to the invention contains a bolt 3 sliding

Le pêne 3 comporte une conformation 4 de commande coopérant avec le barillet non représenté et un carré 6 coulissant dans une lumière 6a du coffre 2 de la serrure.The bolt 3 has a control conformation 4 cooperating with the barrel not shown and a square 6 sliding in a light 6a of the trunk 2 of the lock.

Le pêne 3 comporte enfin un axe 5 coopérant avec une gorge 7. Cette gorge 7 comporte un taquet 8 et un logement 9 pour un ressort 10 monté en compression entre le taquet 8 de la gorge 7 et l'axe 5 du pêne 3. La gorge 7 comporte un organe de retenue 11 apte à retenir le pêne 3 dans la position ouverte ou fermée de la serrure.The bolt 3 finally comprises an axis 5 cooperating with a groove 7. This groove 7 includes a cleat 8 and a housing 9 for a spring 10 mounted in compression between the cleat 8 of the groove 7 and the axis 5 of the bolt 3. The groove 7 comprises a retainer 11 able to retain the bolt 3 in the open or closed position of the lock.

Cet organe 11 de retenue est par exemple une partie en relief guidée dans une conformation 12, par exemple une découpe en U pratiquée dans le couvercle 2a du coffre 2. De préférence, la branche avant de la conformation ou découpe 12 en U est plus longue que la branche arrière de cette conformation 12.This retaining member 11 is for example a portion in relief guided in a conformation 12, for example a U-shaped cut in the cover 2a of the chest 2. Preferably, the front branch of the U-shaped conformation or cutout 12 is longer than the rear branch of this conformation 12.

Un cliquet 13 est monté pivotant à la manière d'un levier autour d'un axe 14 au moyen de deux tétons 15a, 15b de section carrée engagés dans deux perçages 16a, 16b du coffre 2. Le cliquet 13, découpé et plié dans une tôle métallique, comporte deux parties sensiblement planes 17, 18, pliées perpendiculairement l'une à l'autre.A pawl 13 is pivotally mounted in the manner of a lever around an axis 14 by means of two pins 15a, 15b of square section engaged in two holes 16a, 16b of the trunk 2. The pawl 13, cut and folded in a metal sheet, comprises two substantially flat parts 17, 18, folded perpendicular to each other.

La partie 17 du cliquet 13 présente une section importante dont la largeur correspond sensiblement à l'épaisseur du pêne 3. Part 17 of pawl 13 has a large section whose width roughly corresponds to the thickness of the bolt 3.

La partie 18 du cliquet 13 présente un contour courbe ou circulaire destiné à venir en butée contre une vis ou un organe V solidaire du coffre2 de la serrure, après pivotement complet du cliquet 13 dans le sens de la flèche C.Part 18 of pawl 13 has a curved or circular contour intended to come into abutment against a screw or a member V secured to the lock2 of the lock, after complete rotation of the pawl 13 in the direction of arrow C.

En référence aux figures 2 à 5, une serrure selon l'invention représentée dans des positions successives de fonctionnement comporte des éléments identiques ou fonctionnellement équivalents aux éléments de la figure 1, repérés par des chiffres identiques aux chiffres de référence de la figure 1.Referring to Figures 2 to 5, a lock according to the invention shown in successive operating positions have identical elements or functionally equivalent to the elements in Figure 1, identified by numbers identical to the reference figures in Figure 1.

Le couvercle 2a de la serrure selon l'invention n'est pas représenté pour la clarté du dessin.The cover 2a of the lock according to the invention is not shown for the clarity of the drawing.

Malgré cette absence de représentation, le trajet de l'organe 11 de la gorge 7 est imposé par la conformation 12 de guidage du couvercle 2a comme indiqué par les flèches placées à proximité de l'organe 11 de retenue.Despite this absence of representation, the path of the member 11 of the groove 7 is imposed by the conformation 12 for guiding the cover 2a as indicated by the arrows placed near the retaining member 11.

La serrure selon l'invention comporte un barillet 19 fixé dans son logement par une vis 20. Le barillet 19 d'actionnement comporte un panneton 21 commandé par une clé non représentée.The lock according to the invention comprises a barrel 19 fixed in its housing by a screw 20. The actuating barrel 19 comprises a bit 21 controlled by a key not shown.

Sur la figure 2, la serrure en position ouverte présente son pêne 3 retenu à l'intérieur de la serrure par la coopération de l'organe 11 avec la conformation 12 non représentée, tandis que la partie 17 du cliquet 13 repose par gravité sur l'épaisseur du pêne 3 avec liberté de glissement.In FIG. 2, the lock in the open position has its bolt 3 retained at the interior of the lock by the cooperation of the member 11 with the conformation 12 no shown, while the part 17 of the pawl 13 rests by gravity on the thickness of the bolt 3 with freedom of sliding.

Sur la figure 3, dans la phase initiale du mouvement de fermeture de la serrure, le panneton 21 du barillet 19 repousse la gorge 7 vers le haut dans le sens de la flèche 23 en comprimant le ressort hélicoïdal 10 et en soulevant vers le haut l'organe 11 coulissant dans la conformation 12 non représentée, ainsi que le cliquet 13.In FIG. 3, in the initial phase of the closing movement of the lock, the bit 21 of the barrel 19 pushes the groove 7 upwards in the direction of the arrow 23 by compressing the coil spring 10 and lifting upwards the member 11 sliding in the conformation 12 not shown, as well as the pawl 13.

Le cliquet 13 soulevé repose ensuite par sa partie 17 sur l'épaisseur de la gorge 7, en glissant sur l'épaisseur de la gorge 7, lorsque l'on continue la rotation du panneton 21 dans le sens de la flèche 24 correspondant au sens de verrouillage de la serrure.The raised pawl 13 then rests by its part 17 on the thickness of the groove 7, sliding over the thickness of groove 7, when the rotation of the bit 21 in the direction of arrow 24 corresponding to the locking direction of the lock.

Sur la figure 4, lorsque le panneton 21 a été tourné complètement dans le sens de la flèche 25 et que le pêne est verrouillé dans le sens de la flèche 26, la gorge 7 redescend dans le sens de la flèche 27 sous l'action du ressort de compression 10 qui se détend après que l'extrémité du panneton 21 soit sortie de la conformation de commande 4.In FIG. 4, when the bit 21 has been turned completely in the direction arrow 25 and the bolt is locked in the direction of arrow 26, groove 7 descends in the direction of arrow 27 under the action of the compression spring 10 which relaxes after the end of the bit 21 has left the conformation of command 4.

Dans cette position, l'organe 11 de la gorge 7, qui empêche la rentrée du pêne 3, est retenu par la conformation 12 non représentée du couvercle 2a, sans toutefois en atteindre le point le plus bas, en raison du fait que la gorge 7 est retenue en position B de butée sur le haut du barillet 19 d'actionnement, ce qui empêche sa descente complète.In this position, the member 11 of the groove 7, which prevents the retraction of the bolt 3, is retained by the conformation 12 not shown of the cover 2a, without however reach the lowest point, due to the fact that the groove 7 is retained in position B stop on the top of the actuating barrel 19, which prevents its full descent.

Le cliquet 13 retombe par gravité, ou éventuellement sous l'action d'un ressort de précontrainte non représenté, dans le sens de la flèche 28 derrière un décrochement courbe 29 pratiqué sur le pêne 3, de manière à réaliser un arc-boutement derrière ce décrochement 29. Cet arc-boutement du cliquet 13 formant levier de blocage est réalisé par la partie 17 engagée derrière le décrochement 29 du pêne 3 dans la position verrouillée de la figure 4.The pawl 13 falls by gravity, or possibly under the action of a spring prestressing not shown, in the direction of arrow 28 behind a curved recess 29 made on the bolt 3, so as to create a bracing behind this recess 29. This bracing of the pawl 13 forming blocking lever is produced by the part 17 engaged behind the recess 29 of the bolt 3 in the locked position of figure 4.

Cependant, le cliquet 13 en arc-boutement derrière le pêne 3 repose encore par sa partie 17 sur l'extrémité de la gorge 7, en glissant sur l'épaisseur de la gorge 7 laquelle empêche ainsi le pivotement complet du cliquet 13 dans le sens de la flèche C.However, the pawl 13 in bracing behind the bolt 3 still rests by its part 17 on the end of the groove 7, sliding over the thickness of the groove 7 which thus prevents complete rotation of the pawl 13 in the direction of the arrow vs.

Lors du déverrouillage de la serrure selon l'invention, les mouvements sont reproduits en sens inverse et le panneton 21 soulève la gorge 7 qui à son tour soulève le cliquet 13 et permet ainsi le recul du pêne 3.When unlocking the lock according to the invention, the movements are reproduced in reverse and the bit 21 raises the groove 7 which in turn raises the pawl 13 and thus allows the retraction of the bolt 3.

Cependant, lorsque l'on appuie sur le pêne 3 dans le sens correspondant au coulissement 30 du pêne 3, le recul du pêne 3 est empêché par la partie 17 du cliquet 13. Lors d'une tentative d'effraction par enfoncement du pêne, la poussée opposée au cliquet 13 est encaissée par l'arc-boutement produit par le cliquet 13.However, when the bolt 3 is pressed in the direction corresponding to the sliding 30 of the bolt 3, the retraction of the bolt 3 is prevented by the part 17 of the pawl 13. During an attempted break-in by pushing in the bolt, the thrust opposite the pawl 13 is cashed by the bracing produced by pawl 13.

Cependant, après destruction de la partie centrale du barillet 19, il est possible d'introduire un outil à travers le passage du barillet 19 pour tenter de soulever la gorge 7, puis tenter de rétracter le pêne 3 dans le sens rentrant tout en maintenant la gorge 7 en position soulevée.However, after destruction of the central part of the barrel 19, it is possible to introduce a tool through the passage of the barrel 19 in an attempt to lift the groove 7, then attempt to retract the bolt 3 in the inward direction while maintaining the groove 7 in raised position.

Grâce à l'invention, la destruction du barillet 19 aboutit à un blocage de la serrure selon l'invention et empêche l'enfoncement du pêne 3 dans le sens rentrant, même en cas de rupture de barillet. Thanks to the invention, the destruction of the barrel 19 results in a blockage of the lock according to the invention and prevents the bolt 3 from being pushed in the re-entrant direction, even in case of barrel rupture.

En effet, sur la figure 5, en cas de rupture et d'enlèvement du barillet 19 d'actionnement, la gorge 7 qui n'est plus retenue en position B de butée sur le haut de barillet effectue sa descente complète, et l'organe 11 de la gorge 7 atteint le point le plus bas de la conformation 12 du couvercle 2a.In fact, in FIG. 5, in the event of rupture and removal of the barrel 19 actuation, the groove 7 which is no longer retained in the stop position B on the top of barrel performs its complete descent, and the member 11 of the groove 7 reaches the point the lower of the conformation 12 of the cover 2a.

Le cliquet 13, qui n'est plus en appui sur l'extrémité de la gorge 7 après la descente complète de la gorge 7 et de l'organe 11 de la gorge 7, retombe par gravité, ou éventuellement sous l'action d'un ressort de précontrainte non représenté, dans le sens de la flèche C.The pawl 13, which is no longer supported on the end of the groove 7 after the complete descent of the throat 7 and of the member 11 of the throat 7, falls by gravity, or possibly under the action of a prestressing spring not shown, in the direction of arrow C.

Le pivotement du cliquet 13 s'effectue complètement dans le sens de la flèche C, pour atteindre la position de butée du contour courbe ou circulaire de la partie 18 du cliquet 13 contre une vis ou un organe V solidaire du coffre2 de la serrure.The pawl 13 is pivoted completely in the direction of the arrow C, to reach the stop position of the curved or circular outline of part 18 of the pawl 13 against a screw or a member V secured to the lock2 of the lock.

Le cliquet 13 dans cette position de butée constitue un obstacle qui empêche la rentrée du pêne 3, en bloquant complètement la serrure dans sa position de verrouillage.The pawl 13 in this stop position constitutes an obstacle which prevents re-entry of the bolt 3, completely blocking the lock in its position locking.
