Description

Cylindre de sécurité à panneton réglableSafety cylinder with adjustable bit
La présente invention concerne un cylindre de sécurité pour serrure.The present invention relates to a security cylinder for a lock.
De manière habituelle, les cylindres de sécurité comportent un stator dans lequel peut tourillonner un rotor. Le rotor est bloqué en rotation dans le stator sous l'effet de moyens de clavetage, l'introduction d'une clé dans le rotor permettant le désenclavetage desdits moyens et la libération en rotation du rotor dans le stator.Usually, the safety cylinders include a stator in which a rotor can rotate. The rotor is locked in rotation in the stator under the effect of keying means, the introduction of a key in the rotor allowing the opening of said means and the release in rotation of the rotor in the stator.
L'entraînement en rotation du rotor provoque 1 ' entraînement en rotation d'un panneton par l'intermédiaire d'un entraîneur en prise avec le rotor et avec la clé introduite. Le panneton commande lors de sa rotation le déplacement des organes de la serrure, par exemple le pêne de la serrure. Lorsque la clé est retirée, les moyens de clavetage bloquent de nouveau en rotation le rotor, ce qui verrouille le panneton en position.The rotational drive of the rotor causes one drive in rotation of a bit by means of a driver engaged with the rotor and with the key inserted. The bit controls during its rotation the movement of the lock members, for example the bolt of the lock. When the key is removed, the keying means again block the rotor in rotation, which locks the bit in position.
Généralement, un cylindre est monté sur un type de serrure particulier, le panneton étant positionné de manière déterminée par rapport à l'agencement de ladite serrure pour pouvoir actionner le pêne par exemple.Generally, a cylinder is mounted on a particular type of lock, the bit being positioned so determined relative to the arrangement of said lock in order to be able to actuate the bolt for example.
On connaît, par FR-A-2 769 658, un barillet de serrure dit « universel » qui comporte un moyen d'indexage, tel qu'une couronne dentée portée par le panneton, coopérant avec une couronne dentée portée par l'entraîneur et actionnable après montage du barillet depuis la face opposée du barillet. Ainsi, on exerce une pression sur l'entraîneur de sorte que celui-ci désengage sa couronne dentée de la couronne dentée du panneton pour positionner celui-ci à la position angulaire souhaitée .We know, from FR-A-2 769 658, a so-called "universal" lock barrel which includes an indexing means, such as a toothed ring carried by the bit, cooperating with a toothed ring carried by the driver and actuable after mounting the barrel from the opposite side of the barrel. Thus, pressure is exerted on the driver so that the latter disengages its toothed ring from the toothed ring of the bit to position the latter at the desired angular position.
Bien que ce dispositif offre une possibilité de commande du panneton intéressante, la présence d'au moins un moyen de rappel élastique permettant l'engagement et le désengagement de la couronne de l'entraîneur avec celle du panneton peut conduire, du fait de l'usure dudit moyen de rappel élastique, à un mauvais positionnement du panneton ou même à un blocage des couronnes dentées rendant inutilisable le cylindre.Although this device offers an interesting possibility of controlling the bit, the presence of at least one elastic return means allowing the engagement and disengagement of the crown of the coach with that of the bit can lead, due to the wear of said elastic return means, improper positioning of the bit or even a blocking of the toothed rings making the cylinder unusable.
La présente invention a pour but de proposer un cylindre dont le panneton est positionnable facilement et sûrement à plusieurs positions angulaires permettant l'adaptation du cylindre à différents types de serrure.The object of the present invention is to propose a cylinder whose bit is easily and surely positionable at several angular positions allowing the adaptation of the cylinder to different types of lock.
A cet effet, l'invention a pour objet un cylindre pour serrure de sécurité du type comportant un barillet ou stator dans lequel est monté tourillonnant un rotor, des moyens de clavetage bloquant en rotation ledit rotor par rapport au barillet et étant désenclavetés par l'introduction d'une clé dans le rotor pour libérer celui-ci en rotation dans le barillet, l'entraînement en rotation du rotor provoquant l'entraînement en rotation d'un panneton en prise sur un entraîneur lui-même en prise avec la clé dans le rotor, caractérisé en ce que le panneton est monté sur l'extrémité de l'entraîneur par l'intermédiaire de moyens de serrage dudit panneton contre ladite extrémité, lesdits moyens de serrage étant entraînables entre une position dans laquelle ils maintiennent le panneton serré contre l'entraîneur et au moins une position dans laquelle lesdits moyens de serrage sont écartés dudit panneton et autorisent un changement de position angulaire de celui-ci.To this end, the subject of the invention is a cylinder for a security lock of the type comprising a barrel or stator in which a rotor is journalled, keying means blocking said rotor in rotation relative to the barrel and being released by the introduction of a key in the rotor to release the latter in rotation in the barrel, the rotational drive of the rotor causing the rotation of a bit engaged on a driver itself engaged with the key in the rotor, characterized in that the bit is mounted on the end of the driver by means of clamping means of said bit against said end, said tightening means being able to be driven between a position in which they hold the bit tight against the driver and at least one position in which said tightening means are spaced from said bit and allow a change of angular position from that -this.
Ainsi, de manière avantageuse, il suffit donc d'actionner les moyens de serrage pour amener ceux-ci soit à la position de serrage du panneton permettant le fonctionnement du cylindre soit à une position d' actionnement du panneton de manière à amener celui-ci à une position différente pour s'adapter à des structures de serrure différentes avant de monter ledit cylindre.Thus, advantageously, it is therefore enough to actuate the clamping means to bring them either to the clamping position of the bit allowing the cylinder to operate or to a position for actuating the bit so as to bring the latter at a different position to adapt to different lock structures before mounting said cylinder.
Selon une forme de réalisation particulièrement avantageuse, les moyens de serrage sont constitués par une vis traversant le panneton et engagée dans un alésage fileté ménagé à l'extrémité de l'entraîneur. Ainsi, par vissage, on serre le panneton sur l'entraîneur et par dévissage on écarte la vis du panneton qui peut alors être positionné selon une position angulaire différente.According to a particularly advantageous embodiment, the clamping means consist of a screw passing through the bit and engaged in a threaded bore formed at the end of the driver. Thus, by screwing, the bit is tightened on the driver and by unscrewing it spreads the screw of the bit which can then be positioned in a different angular position.
De préférence, l'extrémité de l'entraîneur ou le panneton comporte un organe mâle coopérant avec un organe femelle ménagé en regard sur l'autre organe, un joint élastiquement déformable étant logé entre l'entraîneur et le panneton de telle sorte que, lors de la manoeuvre du panneton, 1 ' écartement des moyens de serrage est empêché. Ainsi, l'organe mâle peut être un téton coopérant avec un évidement.Preferably, the end of the driver or the bit comprises a male member cooperating with a female member arranged opposite the other member, an elastically deformable seal being housed between the driver and the bit so that, when from the operation of the bit, the spacing of the clamping means is prevented. Thus, the male member can be a stud cooperating with a recess.
On décrira maintenant l'invention plus en détails en référence au dessins dans lequel :The invention will now be described in more detail with reference to the drawings in which:
la figure 1 représente une vue en coupe longitudinale du cylindre selon un exemple de réalisation de l'invention ; et la figure 2 représente une vue du cylindre sur lequel plusieurs positions possibles du panneton sont représentées.Figure 1 shows a longitudinal sectional view of the cylinder according to an exemplary embodiment of the invention; and Figure 2 shows a view of the cylinder on which several possible positions of the bit are shown.
Un cylindre selon l'invention comporte un barillet ou stator 1 dans lequel est monté tourillonnant un rotor 2, des moyens de clavetage bloquant le rotor 2 en rotation par rapport au barillet 1 . Le barillet 1 et le rotor 2 sont logés dans un corps de cylindre C.A cylinder according to the invention comprises a barrel or stator 1 in which a rotor 2 is journalled, keying means blocking the rotor 2 in rotation relative to the barrel 1. Barrel 1 and rotor 2 are housed in a cylinder body C.
Lorsqu'une clé est introduite dans le cylindre, les moyens de clavetage sont désenclavetés ce qui autorise l'entraînement en rotation du rotor 2 dans le barillet 1. La clé vient également en prise avec un entraîneur 3.When a key is introduced into the cylinder, the keying means are released, which allows the rotor 2 to be driven in rotation in the barrel 1. The key also comes into engagement with a driver 3.
Cet entraîneur 3 est également en prise à son extrémité opposée avec un panneton 4. Ce panneton 4 est fixé à l'extrémité de l'entraîneur 3 à l'aide d'une vis 5 engagé dans un alésage fileté 6 ménagé à ladite extrémité de 1 ' entraîneur 3.This driver 3 is also engaged at its opposite end with a bit 4. This bit 4 is fixed to the end of the driver 3 using a screw 5 engaged in a threaded bore 6 formed at said end of 1 coach 3.
De préférence, l'extrémité de l'entraîneur 3 est pourvu d'au moins un téton 3a en saillie coopérant avec un évide ent 4a ménagé en correspondance sur le panneton 4 ou tout autre moyen de coopération. Un joint 9 élastiquement déformable est positionné entre l'entraîneur 3 et le panneton 4 de telle sorte que, lors de la manoeuvre du panneton 4, le dévissage de la vis 5 est empêché.Preferably, the end of the driver 3 is provided with at least one protruding stud 3a cooperating with a recess ent 4a formed in correspondence on the bit 4 or any other means of cooperation. An elastically deformable seal 9 is positioned between the driver 3 and the bit 4 so that, when the bit 4 is operated, the unscrewing of the screw 5 is prevented.
Le cylindre comporte une entrée de clé 7 et, sur sa face opposée, une ouverture 8 ménagée dans le corps C du cylindre et qui débouche en regard de la tête 5a de la vis 5. De cette manière, la tête 5a de la vis 5 est accessible et peut être actionnée depuis l'extérieur du cylindre.The cylinder has a key entry 7 and, on its opposite face, an opening 8 formed in the body C of the cylinder and which opens opposite the head 5a of the screw 5. In this way, the head 5a of the screw 5 is accessible and can be operated from outside the cylinder.
Lorsque la vis 5 est vissée dans l'entraîneur 3, le panneton 4 est maintenu par serrage à une position déterminée. Si on souhaite modifier la position de ce panneton 4, plus précisément la position angulaire de sa saillie 4b, il convient de dévisser la vis 5. En effet, le panneton 4 n'est plus serré par la vis 5 contre l'entraîneur 3 et il est alors possible de positionner ledit panneton 4 à une autre position angulaire souhaitée comme celles représentés à la figure 2. On revisse ensuite la vis 5 pour bloquer le panneton 4 à cette nouvelle position.When the screw 5 is screwed into the driver 3, the bit 4 is held by tightening at a determined position. If you want to change the position of this bit 4, more precisely the angular position of its projection 4b, it is necessary to unscrew the screw 5. In fact, the bit 4 is no longer tightened by the screw 5 against the driver 3 and it is then possible to position said bit 4 to another desired angular position like those shown in Figure 2. Then screw the screw 5 to lock the bit 4 at this new position.
Il est donc possible de modifier de manière simple le cylindre pour adapter celui-ci à différents types de serrures présentant une structure différente afin de le monter dans lesdites serrures. It is therefore possible to modify the cylinder in a simple manner to adapt it to different types of locks having a different structure in order to mount it in said locks.
