Abstract

The key consists of a head (1) and a shank (2) with projections or recesses which interact with radially mobile components to lock or release the barrel. It incorporates an axially sliding and spring-loaded sleeve (12) which goes over the shank in its rest position to protect the projections or recesses. The sleeve's spring (5) also operates a pusher (4) controlling a mobile component (8) on the key shank.

Description

La présente invention concerne une clé 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, tels que des tailles ou des crans par exemple, coopérant avec des organes mobiles, par exemple radialement, pour le verrouillage en rotation du barillet.The present invention relates to a key intended to cooperate with the cylinder of a lock cylinder to release said barrel in rotation, the key comprising a tail connected to an operating head, the tail being provided with reliefs and / or valleys, such as sizes or notches for example, cooperating with moving parts, for example example radially, for locking in rotation of the barrel.

Lors de l'utilisation de ce type de clé, des risques d'endommagement de la clé peuvent intervenir au niveau des reliefs et des creux, par exemple lorsque la clé traíne dans un sac, des poches ou tombe par terre.When using this type of key, risks damage to the key can occur at the reliefs and hollows, for example when the key is lying around in a bag, pockets or fall to the ground.

Ces endommagements éventuels peuvent nuire au fonctionnement de la clé dans la serrure.These possible damages can harm the operation of the key in the lock.

En outre le code de la clé peut, dans certains cas, être "lu" par des personnes malintentionnées qui peuvent ainsi en fabriquer un double. In addition, the key code may in some cases be "read" by malicious people who can thus make a double.

De plus, les creux et reliefs présentent généralement des arêtes tranchantes qui peuvent endommager les poches des vêtements des utilisateurs ou griffer les objets renfermés dans les sacs à main.In addition, the hollows and reliefs generally have sharp edges that can damage the pockets of users' clothes or clawing enclosed objects in handbags.

La présente invention vise à pallier ces inconvénients en proposant une clé protégée contre des détériorations de l'extérieur et contre des endommagements qu'elle pourrait occasionner.The present invention aims to overcome these drawbacks by offering a key protected against damage to outside and against damage it could cause.

A cet effet, la clé selon l'invention est caractérisée en ce qu'elle comporte une enveloppe coulissante rappelée par un moyen de rappel élastique tel qu'un ressort en une position de repos dans laquelle ladite enveloppe recouvre au moins partiellement la queue de clé afin de protéger les creux et/ou les reliefs de ladite clé.To this end, the key according to the invention is characterized in what it includes a sliding envelope recalled by an elastic return means such as a spring in one rest position in which said envelope covers at least partially the key tail to protect the hollow and / or the reliefs of said key.

Une clé selon l'invention peut être de tout type connu. En particulier, la clé peut être une clé à élément mobile dont la queue comprend 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 de serrure et une position de repos, ledit élément mobile étant 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.A key according to the invention can be of any known type. In in particular, the key may be a key with a movable element, the tail comprises a movable element arranged to be moved into a transverse bore of the key shank between an active position in which he cooperates with a complementary locking member of the barrel in the lock cylinder and a rest position, said element mobile being subjected to the action of an axial pusher called back by spring and projecting, in the rest position, at the end of the tail opposite the head of the key.

L'élément ou 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.The movable element or member is thus deleted in the position of rest, while the free end of the pusher, coming abut against a fixed abutment surface of the lock, determines a very precise useful travel for the pusher.

De préférence, l'organe mobile et le poussoir coopèrent par des profils de came complémentaires, par exemple des surfaces coniques complémentaires. Preferably, the movable member and the pusher cooperate by complementary cam profiles, for example complementary conical surfaces.

Selon une forme de réalisation préférée, 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.According to a preferred embodiment, it is advantageous to provide that the return spring of the envelope acts on the pusher, for example via a cross member mounted in said envelope.

La serrure destinée à être utilisée avec une clé à élément mobile selon l'invention est alors, de préférence, 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 an element key mobile according to the invention is then preferably of the type comprising a cylinder made up of a body provided with a axial bore in which a barrel provided with a key channel, the body and the barrel each comprising a transverse passage housing a locking member complementary to the barrel with respect to the body, said additional locking member being disposed of so as to cooperate, in the unlocked position and before rotation of the barrel, with the movable member of the key for release the rotating barrel.

De préférence, 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.Preferably, the complementary locking member is constituted by 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 :

  • la figure 1 est une vue schématique en coupe axiale, partiellement en plan, de la clé ;
  • la figure 2 est une vue schématique en coupe radiale de la clé ; et
  • la figure 3 est une vue schématique en coupe transversale d'une portion de la serrure.
    • The invention will be clearly understood on reading the following description of an exemplary embodiment, with reference to the appended drawing in which:
  • Figure 1 is a schematic view in axial section, partially in plan, of the key;
  • Figure 2 is a schematic view in radial section of the key; and
  • Figure 3 is a schematic cross-sectional view of a portion of the lock.

    • 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 operating head 1 secured to a tail 2. In the example shown, tail 2 is cylindrical but the invention is applicable to any shape tail, especially an open-end wrench.

    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 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.

    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 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.

    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 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. In the example shown, the shank 2 further comprises a bit 2 'in which opens the bore 7 and the inner casing 12 is split in correspondence.

    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 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. As a result, 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.

    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 ball 21 has been pushed back, against the action of the spring 22, so that its center C ' came inside the bore 20 of the stator (position right in the drawing), an attempt to rotate the rotor pushes the ball 21 back into the bore 20 of the stator, against the action of spring 22 and the rotor can rotate, the ball 21 then being completely erased inside of the bore 20 through the outer wall of the rotor.

    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 ball 21 in the unlocked position is caused by the movement of the movable member 8 of the key when this key is pressed.

    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 venue 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 bore 24 or key channel of the rotor 14, 15, the bit 2 ′ sliding in the internal slot 18 of the rotor, the free end of the pusher 4 having come to bear on a surface (not shown) of the stator, this pusher 4 has slid by a precise distance determined by a stop end of the key. Hole 7 came opposite the ball 21 and the movable member 8 has moved in projection by pushing the ball 21.

    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 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 complementary conical surfaces of head 9 and the notch 10, acting like a cam complementary. When the key is extracted, 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.
