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.
- dynamic keys are to increase security by providing at least one additional locking member participating in the combination of the lock and to increase the mechanical resistance against forced entry by forced rotation. of the barrel.
- the most important advantage of such dynamic keys is that they make the key practically non-reproducible, unlike most ordinary keys 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 be reproduced, in fact generally makes it possible to cut a reproduction after ⁇ reading ⁇ ⁇ Code or after taking an impression on the key without the owner's knowledge, also allows in certain cases an impression by introduction into the key channel of the lock and can also form the basis of a tool for force opening of the lock.
- 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 key 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 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 shank 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 complementary conical surfaces of 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.
