Definitions
- the present invention relates to a key with a movable element, intended to cooperate with the barrel of a cylinder of lock to release said rotating barrel, the key comprising a tail connected to an operating head, the tail being provided with reliefs and / or hollows cooperating with radially movable members for locking in rotation of the barrel, the tail further comprising a mobile element arranged to be moved in a bore transverse of the key tail between an active position in which it cooperates with a locking member complementary to the barrel in the cylinder and a position rest.
- a security lock in which the key cooperates with pistons in several parts, forming complementary organs of lock, especially including balls, but the key itself does not have a moving part so that it does not have the key benefits dynamic.
- the present invention therefore aims to overcome the disadvantages of known locks and keys, in particular by providing a dynamic key in which the element mobile slides transversely to the tail the key without protruding in the rest position and which allows great precision in the movement of this organ mobile.
- the key according to the invention is characterized in that said movable member is subjected to the action of a axial plunger spring-loaded and protruding, rest position, at the end of the tail opposite the head of the key.
- the movable member is thus deleted in rest position, while the free end of the pusher, abutting against a fixed abutment surface of the lock, determines a very useful travel precise for the pusher.
- the member mobile and pusher cooperate by cam profiles complementary, for example conical surfaces complementary.
- the key has a sliding casing returned by spring to a rest position in which said envelope at least partially covers the tail to protect the sizes or notches of said key.
- the spring of envelope reminder acts on the pusher, for example by through a cross member mounted in said envelope.
- the lock intended to be used with the key is of the type comprising a cylinder made up a body provided with an axial bore in which journalled a barrel provided with a key channel, the body and the barrel each comprising a transverse passage housing a member complementary locking of the barrel relative to the body, said complementary locking member being arranged to cooperate, in position of unlocking and before rotation of the barrel, with the member mobile key to release the rotating barrel.
- the complementary locking member consists of a ball recalled by spring and whose center, in the rest position, is arranged in the barrel.
- Figures 1 and 2 represent the key with mobile element or dynamic key according to the invention.
- the key comprises an operating head 1 secured to a tail 2.
- tail 2 is cylindrical but the invention is applicable to any shape tail, especially with an open-end wrench.
- Shank 2 has a blind central bore 3 in which is housed an axial pusher 4 recalled by a spring 5 in a rest position (Figure 1) in which the end free of the pusher 4 protrudes at the end 6 of the tail 2 opposite head 1.
- the shank 2 is provided with a transverse bore 7 opening in the bore 3 and in which is housed a movable member 8 whose role will be explained later.
- the mobile organ 8 is provided, at its internal end, with a section head 9 triangular which, in the rest position, is housed in a notch 10 of complementary profile of the pusher 4.
- the key tail further includes an outer casing 11 adjacent to the head 1 and an internal envelope 12 arranged to be able to slide on the tail 2 and come to stay at the interior of the outer envelope 11.
- the inner envelope 12 is provided with a cross member 13 on which the return spring 5.
- the cross member 13 is therefore in abutment, rest position, on the inner end of the pusher axial 4, which is prevented from leaving the bore 3 by the cooperation of the head 9 of the movable member 8 with the notch 10 of the pusher 4.
- the tail 2 further comprises a bit 2 'in which opens the bore 7 and the inner casing 12 is split in correspondence.
- the lock (FIG. 3) conventionally comprises a rotor or barrel 14, 15 journalling in a bore 16 of a body or stator 17.
- the rotor 14, 15 has a slot radial 18, 19 which, in the locked position (FIG. 3), is in the extension of a bore 20 of the stator 17.
- a ball 21 is housed, in the locking position, at the same time in the slot 18, 19 of the rotor and in the bore 20 of the stator.
- the ball 21 is subjected to the action of a spring 22 pushing it towards the inside of the rotor 14, 15 and it is stopped by a shoulder 23 of the slot 18, 19 in one position such that its center C is in the slot 18, 19 of the rotor.
- the rotor is locked in rotation because any attempt to rotate the rotor 14, 15 tends to push the ball 21 against the shoulder 23.
- This movement of the ball 21 in the unlocked position is caused by the movement of the movable member 8 of the key when this key is pressed.
- the internal envelope 12 bearing by its front face on the periphery of the canal entrance key 24, is pushed into the outer casing 11 at during key insertion.
- Spring 5 therefore does not act more on pusher 4 but, as indicated previously, this pusher 4 is held by the member mobile 8 and its depression produces the translation orthogonal of the movable member 8 by cooperation of conical surfaces complementary to head 9 and the notch 10, acting like a cam complementary.
- the spring 5 comes to act on the cross 13 to bring the envelope internal 12 outside the external envelope 11 and, at the end of stroke, bring the pusher 4 projecting.

Description
La présente invention concerne une clé à élément mobile, destinée à coopérer avec le barillet d'un cylindre de serrure pour libérer ledit barillet en rotation, la clé comportant une queue reliée à une tête de manoeuvre, la queue étant munie de reliefs et/ou de creux coopérant avec des organes mobiles radialement pour le verrouillage en rotation du barillet, la queue comprenant en outre un élément mobile agencé pour être déplacé dans un alésage transversal de la queue de clé entre une position active dans laquelle il coopère avec un organe de verrouillage complémentaire du barillet dans le cylindre et une position de repos.The present invention relates to a key with a movable element, intended to cooperate with the barrel of a cylinder of lock to release said rotating barrel, the key comprising a tail connected to an operating head, the tail being provided with reliefs and / or hollows cooperating with radially movable members for locking in rotation of the barrel, the tail further comprising a mobile element arranged to be moved in a bore transverse of the key tail between an active position in which it cooperates with a locking member complementary to the barrel in the cylinder and a position rest.
De nombreuses versions d'une telle clé à élément mobile, appelée également clé dynamique, ont été proposées et sont utilisées dans la pratique.Many versions of such a moving element key, also called dynamic key, have been proposed and are used in practice.
Les avantages principaux des clés dites dynamiques sont d'augmenter la sécurité par l'apport d'au moins un organe de verrouillage supplémentaire participant à la combinaison de la serrure et d'augmenter la résistance mécanique contre les tentatives d'effraction par rotation à force du barillet. Mais l'avantage le plus important de telles clés dynamiques est de rendre la clé pratiquement non reproductible, contrairement à la plupart des clés ordinaires pour lesquelles les ébauches non taillées sont de fabrication aisée et sont disponibles dans le commerce. Une ébauche de clé, destinée en principe à être taillée selon le code fourni par le propriétaire de la clé ou « lu » par le serrurier sur la clé à reproduire, permet en fait en général de tailler une reproduction après « lecture » du code ou après prise d'empreinte sur la clé à l'insu du propriétaire, permet également dans certain cas une prise d'empreinte par introduction dans le canal de clé de la serrure et peut aussi constituer la base d'un outil d'ouverture à force de la serrure.The main advantages of so-called dynamic keys are increase safety by providing at least one organ additional lock participating in the combination of the lock and increase the mechanical resistance against forced entry attempts by forced rotation barrel. But the most important advantage of such keys dynamic is to make the key practically no reproducible, unlike most keys ordinary for which the uncut blanks are easy to manufacture and are commercially available. A key blank, intended in principle to be cut according to the code provided by the owner of the key or "Read" by the locksmith on the key to reproduce, allows usually pruning a reproduction after "Reading" the code or after taking an impression on the key unbeknownst to the owner, also allows in certain cases taking an impression by entering the key channel of the lock and can also form the basis of a tool force to open the lock.
On connaít, par exemple par FR-A-2 696 776 au nom du demandeur ou FR-A-2 678 670, des serrures dans lesquelles l'élément mobile est déplaçable axialement. L'inconvénient principal des serrures de ce type est que l'organe mobile peut relativement facilement être accessible en l'absence de clé puisque cet organe mobile est en principe en saillie à l'avant du cylindre. Par contre, un avantage de ces serrures est une précision élevée de la course active de l'organe mobile, ce qui améliore la sûreté de la serrure.We know, for example by FR-A-2 696 776 in the name of applicant or FR-A-2 678 670, locks in which the movable element is axially displaceable. Disadvantage main of locks of this type is that the movable member can be relatively easily accessed in the absence key since this movable member is in principle projecting at the front of the cylinder. However, an advantage of these locks is a high precision of the active stroke of the movable member, which improves the security of the lock.
On connaít par ailleurs des serrures du type défini à l'introduction, par exemple par FR-A-2 492 872. Dans ces serrures connues, l'organe mobile est déplaçable orthogonalement à la queue de la clé, dans un alésage perpendiculaire à ladite queue qui est en général plate. La fabrication est relativement complexe et coûteuse, avec des risques élevés de blocage de l'organe mobile. En outre, cet organe fait en général saillie de la clé au repos, ce qui le rend vulnérable et permet surtout de mesurer cette saillie qui pourra être construite fixe sur une ébauche ou un outil d'ouverture. We also know locks of the type defined in the introduction, for example by FR-A-2 492 872. In these known locks, the movable member is movable orthogonally to the tail of the key, in a bore perpendicular to said tail which is generally flat. The manufacturing is relatively complex and expensive, with high risks of blockage of the moving part. In addition, this organ generally protrudes from the key at rest, which makes it vulnerable and above all makes it possible to measure this projection which can be built fixed on a blank or an opening tool.
On connaít en outre par FR-A-446 622, une serrure de sûreté dans laquelle la clé coopère avec des pistons en plusieurs parties, formant des organes complémentaires de verrouillage, en particulier comprenant des billes, mais la clé elle-même ne comporte pas d'élément mobile de sorte qu'elle ne présente pas les avantages liés aux clés dynamiques. La présente invention vise en conséquence à pallier les inconvénients des serrures et clés connues, en particulier en fournissant une clé dynamique dans laquelle l'élément mobile coulisse transversalement par rapport à la queue de la clé sans être en saillie en position de repos et qui permette une grande précision du déplacement de cet organe mobile.We also know from FR-A-446 622, a security lock in which the key cooperates with pistons in several parts, forming complementary organs of lock, especially including balls, but the key itself does not have a moving part so that it does not have the key benefits dynamic. The present invention therefore aims to overcome the disadvantages of known locks and keys, in particular by providing a dynamic key in which the element mobile slides transversely to the tail the key without protruding in the rest position and which allows great precision in the movement of this organ mobile.
A cet effet, la clé selon l'invention est caractérisée en ce que ledit organe mobile est soumis à l'action d'un poussoir axial rappelé par ressort et faisant saillie, en position de repos, à l'extrémité de la queue opposée à la tête de la clé. L'organe mobile est ainsi effacé en position de repos, alors que l'extrémité libre du poussoir, venant buter contre une surface de butée fixe de la serrure, détermine une course de translation utile très précise pour le poussoir.To this end, the key according to the invention is characterized in that said movable member is subjected to the action of a axial plunger spring-loaded and protruding, rest position, at the end of the tail opposite the head of the key. The movable member is thus deleted in rest position, while the free end of the pusher, abutting against a fixed abutment surface of the lock, determines a very useful travel precise for the pusher.
Selon une forme de réalisation de l'invention, l'organe mobile et le poussoir coopèrent par des profils de came complémentaires, par exemple des surfaces coniques complémentaires.According to one embodiment of the invention, the member mobile and pusher cooperate by cam profiles complementary, for example conical surfaces complementary.
De préférence, la clé comporte une enveloppe coulissante rappelée par ressort en une position de repos dans laquelle ladite enveloppe recouvre au moins partiellement la queue de clé afin de protéger les tailles ou les crans de ladite clé.Preferably, the key has a sliding casing returned by spring to a rest position in which said envelope at least partially covers the tail to protect the sizes or notches of said key.
Dans ce cas, il est avantageux de prévoir que le ressort de rappel de l'enveloppe agit sur le poussoir, par exemple par l'intermédiaire d'une traverse montée dans ladite enveloppe.In this case, it is advantageous to provide that the spring of envelope reminder acts on the pusher, for example by through a cross member mounted in said envelope.
La serrure destinée à être utilisée avec la clé selon l'invention est du type comprenant un cylindre constitué d'un corps muni d'un alésage axial dans lequel tourillonne un barillet muni d'un canal de clé, le corps et le barillet comportant chacun un passage transversal logeant un organe de verrouillage complémentaire du barillet par rapport au corps, ledit organe de verrouillage complémentaire étant disposé de manière à coopérer, en position de déverrouillage et avant rotation du barillet, avec l'organe mobile de la clé pour libérer le barillet en rotation.The lock intended to be used with the key according to the invention is of the type comprising a cylinder made up a body provided with an axial bore in which journalled a barrel provided with a key channel, the body and the barrel each comprising a transverse passage housing a member complementary locking of the barrel relative to the body, said complementary locking member being arranged to cooperate, in position of unlocking and before rotation of the barrel, with the member mobile key to release the rotating barrel.
Selon l'invention, l'organe de verrouillage complémentaire est constitué par une bille rappelée par ressort et dont le centre, en position de repos, est disposé dans le barillet.According to the invention, the complementary locking member consists of a ball recalled by spring and whose center, in the rest position, is arranged in the barrel.
L'invention sera bien comprise à la lecture de la
description suivante d'un exemple de réalisation, en
référence au dessin annexé dans lequel :
On se réfère tout d'abord aux figures 1 et 2 qui représentent la clé à élément mobile ou clé dynamique selon l'invention.We first refer to Figures 1 and 2 which represent the key with mobile element or dynamic key according to the invention.
La clé comprend une tête de manoeuvre 1 solidaire d'une
queue 2. Dans l'exemple représenté, la queue 2 est
cylindrique mais l'invention est applicable à toute forme
de queue, en particulier à une clé plate.The key comprises an
La queue 2 comporte un alésage central borgne 3 dans lequel
est logé un poussoir axial 4 rappelé par un ressort 5 dans
une position de repos (figure 1) dans laquelle l'extrémité
libre du poussoir 4 est en saillie à l'extrémité 6 de la
queue 2 opposée à la tête 1. Shank 2 has a blind
La queue 2 est munie d'un alésage transversal 7 débouchant
dans l'alésage 3 et dans lequel est logé un organe mobile 8
dont le rôle sera expliqué ultérieurement. L'organe mobile
8 est muni, à son extrémité interne, d'une tête 9 à section
triangulaire qui, en position de repos, est logée dans une
encoche 10 de profil complémentaire du poussoir 4.The
La queue de clé comporte en outre une enveloppe externe 11
adjacente à la tête 1 et une enveloppe interne 12 agencée
pour pouvoir coulisser sur la queue 2 et venir se loger à
l'intérieur de l'enveloppe externe 11. L'enveloppe interne
12 est munie d'une traverse 13 sur laquelle s'appuie le
ressort de rappel 5. La traverse 13 est donc en appui, en
position de repos, sur l'extrémité interne du poussoir
axial 4, qui est empêché de sortir de l'alésage 3 par la
coopération de la tête 9 de l'organe mobile 8 avec
l'encoche 10 du poussoir 4. Dans l'exemple représenté, la
queue 2 comporte en outre un panneton 2' dans lequel
débouche l'alésage 7 et l'enveloppe interne 12 est fendue
en correspondance.The key tail further includes an
La serrure (figure 3) comprend, de manière classique, un
rotor ou barillet 14, 15 tourillonnant dans un alésage 16
d'un corps ou stator 17. Le rotor 14, 15 comporte une fente
radiale 18, 19 qui, en position de verrouillage (figure 3),
est dans le prolongement d'un alésage 20 du stator 17. Une
bille 21 est logée, en position de verrouillage, à la fois
dans la fente 18, 19 du rotor et dans l'alésage 20 du
stator. La bille 21 est soumise à l'action d'un ressort 22
la repoussant vers l'intérieur du rotor 14, 15 et elle est
arrêtée par un épaulement 23 de la fente 18, 19 en une
position telle que son centre C est dans la fente 18, 19 du
rotor. Il en résulte que le rotor est verrouillé en
rotation car toute tentative de rotation du rotor 14, 15
tend à repousser la bille 21 contre l'épaulement 23. The lock (FIG. 3) conventionally comprises a
rotor or
Au contraire, lorsque la bille 21 a été repoussée, contre
l'action du ressort 22, de telle sorte que son centre C'
est venu à l'intérieur de l'alésage 20 du stator (position
à droite dans le dessin), une tentative de rotation du
rotor repousse la bille 21 dans l'alésage 20 du stator,
contre l'action du ressort 22 et le rotor peut tourner, la
bille 21 étant ensuite complètement effacée à l'intérieur
de l'alésage 20 par la paroi externe du rotor.On the contrary, when the
Ce déplacement de la bille 21 en position de déverrouillage
est provoqué par le déplacement de l'organe mobile 8 de la
clé lors de l'enfoncement de cette clé.This movement of the
En effet, à la fin de l'enfoncement de la clé dans
l'alésage 24 ou canal de clé du rotor 14, 15, le panneton
2' coulissant dans la fente interne 18 du rotor,
l'extrémité libre du poussoir 4 étant venu en appui sur une
surface (non représentée) du stator, ce poussoir 4 a
coulissé d'une distance précise déterminée par une butée de
fin de course de la clé. L'alésage 7 est venu en regard de
la bille 21 et l'organe mobile 8 s'est déplacé en saillie
en repoussant la bille 21.Indeed, at the end of the insertion of the key in
the
Dans l'exemple représenté, l'enveloppe interne 12, en appui
par sa face frontale sur la périphérie de l'entrée du canal
de clé 24, est repoussée dans l'enveloppe extérieure 11 au
cours de l'enfoncement de la clé. Le ressort 5 n'agit donc
plus sur le poussoir 4 mais, comme on l'a indiqué
précédemment, ce poussoir 4 est maintenu par l'organe
mobile 8 et son enfoncement produit la translation
orthogonale de l'organe mobile 8 par coopération des
surfaces coniques complémentaires de la tête 9 et de
l'encoche 10, agissant à la manière de cames
complémentaires. A l'extraction de la clé, le ressort 5
vient agir sur la traverse 13 pour ramener l'enveloppe
interne 12 hors de l'enveloppe externe 11 et, en fin de
course, ramener le poussoir 4 en saillie.In the example shown, the
