Definitions

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.
the key code may in some cases be "read” by malicious people who can thus make a double.
the hollows and reliefs generally have sharp edges that can damage the pockets of users' clothes or clawing enclosed objects in handbags.
the present invention aims to overcome these drawbacks by offering a key protected against damage to outside and against damage it could cause.
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.
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.
a key according to the invention can be of any known type.
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.
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.
the movable member and the pusher cooperate by complementary cam profiles, for example complementary conical surfaces.
the return spring of the envelope acts on the pusher, for example via a cross member mounted in said envelope.
the lock intended to be used with an element key mobile 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.
the complementary locking member is constituted by 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.
