Abstract

The key has a normal shank with one or more grooves or notches milled or drilled into it. Magnetic features can also be included. The key also incorporates a dovetail-section moving element which may comprise a dovetail-section slide. The slide is spring loaded and fits into a groove in the shank. When the key is inserted in the lock the slide is actuated by an internal stop and moves along the slot to take up its true position to match the lock tumberls.

Description

D E S C R I P T I O N
Clé à systàme mécanique pour mécanismes de sécurité
L'invention consiste en une clé à système mécarique, comportant une ou' plusieurs parties fixes et une ou plusieurs parties mobiles.DESCRIPTION
Mechanical key for security mechanisms
The invention consists of a mechanical system key, comprising one or more fixed parts and one or more mobile parts.

Sous l'action combinée de l'enfoncement de la clé dans le rotor et de la résistance opposée par une ou plusreurs butées placées dans ce rotor, la ou les parties mobiles recutent, prenant par rappart à la ou aux parties fixes une position définie, talle que celle-ci permet le déverouillage du roter du cylindre. La forme de la clé est donc différente durant son fonctionnement dans le rotor de celle qu'elle présente hors utitisation. Under the combined action of driving the key into the rotor and the resistance opposed by one or more stops placed in this rotor, the movable part or parts receive, taking in relation to the fixed part or parts a defined position, tiller that this allows the unlocking of the roter of the cylinder. The shape of the key is therefore different during its operation in the rotor from that which it exhibits outside use.

L'ignorance de la position de déverouiullage rend impossible la reproduetion d'une cté statique simple, extérieurement identique, qui puisse fonctionner. Ignorance of the unlock position makes it impossible to reproduce a simple static side, externally identical, which can work.

On connait des systèmes dans lesquels c'est la clé elle-méme qui, en se vérouillant, autorise la libération du roter dans te cylindre, mais ce cylindre doit étre spécifique de la clé. We know systems in which it is the key itself which, by locking, authorizes the release of the burp in the cylinder, but this cylinder must be specific to the key.

Cette solution présente plusieurs inconvénients :
- poids et encombrement de la clé.This solution has several drawbacks:
- weight and size of the key.

- complexité et prix de reuient du système. - complexity and cost of the system.

- et. surtout, ce type de clé ne peut s'adapter aux cylindres des méca
nismes de sécurité traditionnels existant sur le marché, puisqu'elle
contraint à une inversion des principes d'exécution des dispositifs
connus.- and. above all, this type of key cannot be adapted to the cylinders of the mechanics
traditional security mechanisms existing on the market, since it
forced to reverse the principles of execution of the devices
known.

La présente invention pallie ces inconvénients tout en offrant une sécurité identique. The present invention overcomes these drawbacks while providing identical security.

Le système, objet de la présente invention, comprend deux éléments :
1 - la clé mécanique
2 - la système de butée dans le mécanisme de sécurité 1 - La clé mécanique
Elle se compose de :
A - Une ou plusieurs parties fixes, compertant ou non, tailles, fraisures,
aimants ou autres, qui, lors de la mise en oeuure de la clé, alignent
une partie des goupilles, paillettes, gorges, aimants etc ... vérouit
lant te roton dans le mécanisme de sécurité. The system which is the subject of the present invention comprises two elements:
1 - the mechanical key
2 - the stop system in the safety mechanism 1 - The mechanical key
It consists of:
A - One or more fixed parts, whether or not comperting, sizes, countersinks,
magnets or others, which, when the key is put into operation, align
part of the pins, glitter, grooves, magnets etc ...
lant te roton in the safety mechanism.

B - Une ou plusieurs parties mobiles, cenlissantes, compontant ou
non des tailles, fraisures, a@mants ou autres, qui, lors de
la mise en oeuvre de la clé dans le rotor, alignent le reste
des goupilles, paillettes, gorges, aimants ou autres en fonc
tion d'un déplacement de ces parties mobiles, déplacement défi
ni par l'entrée en contact desdites parties mobiles avec un
dispositif de butées placé dans le rotor du cylindre.B - One or more moving, cenlantes, compontant or
not sizes, millings, a @ mants or others, which, when
the implementation of the key in the rotor, align the rest
pins, glitter, grooves, magnets or others in function
tion of a displacement of these moving parts, challenge displacement
nor by the coming into contact of said moving parts with a
stop device placed in the cylinder rotor.

Ces parties mobiles peuvent étre indépendantes les unes des autres ou asservies' entre elles. These moving parts can be independent of each other or enslaved to each other.

Après extraction de la clé hors du cylindre, l'ensemble mobile se

These places of itself in its initial position of rest under the action of a thrust created by mechanical or magnetic means (springs or magnets).

Une variänte moins élaborée peut étre réalisée sans moyen de rappel automatique des parties mobiles. Dans ce cas la position des parties mobiles autorisant le fonctionnement est recherchée par poussée manuelle. A less elaborate variety can be produced without means of automatic recall of the moving parts. In this case the position of the moving parts authorizing the operation is sought by manual pushing.

Le profil comme la forme de cette clé mécanique sont laissés à option préférentielle suivant le type de mécanisme de sécurité. The profile as well as the shape of this mechanical key are left to preferential option depending on the type of safety mechanism.

Ci-joint quelques exemples de clés mécaniques conformes à l'invention. Attached are some examples of mechanical keys according to the invention.
