Definitions

  • the invention relates to a locking device according to the preamble of the first claim, which is particularly suitable for locking systems in buildings, vehicles, furniture, cash register cabinets, switch cabinets, key switches etc.
  • the invention also relates to a method for preventing opening of a locking device according to the preamble of a further independent patent claim.
  • Locking devices with mechanically and electronically controlled locking elements are known. They have all the properties of conventional purely mechanical locking devices. The additional electronically controlled locking system also allows you to activate and lock keys individually. With mechatronic locking devices, additional flexibility in the shooting organization can be achieved.
  • the electronically controlled locking system is based on data transmission between an electronic module on the key side and an electronic module on the lock side.
  • This data transmission can be done by touch - e.g. by means of electrical contacts on the key and lock - or without contact - for example by means of electromagnetic induction - take place; Data can be transferred in one or both directions.
  • the transmitted data in the lock-side electronic module is used to check whether the inserted key is authorized to access. If this is the case, a lock-side motor is activated, which moves an additional, electronically controlled locking element in such a way that it releases the SchHess cylinder.
  • Known mechatronic locking devices are particularly susceptible to the effects of vibrations and / or shocks or magnetic influences. Suitable external influences of this type make it possible to transfer the electronically controlled locking element from its locked position into the open position.
  • the electronically controlled locking can be opened with only mechanical and / or magnetic means, without having to insert a suitably electronically coded key.
  • a vibration of constant frequency could be applied from the outside to the closing device; when the frequency is selected appropriately, the electronically controlled blocking element starts to resonate and changes its position due to hardly predictable interactions with other elements.
  • Another unlocking effect can be achieved by hitting the locking device.
  • a pulse can also be composed of monochromatic vibrations, so that the vibration can be regarded as a special case of the stroke.
  • the object of the invention is to provide a mechatronic locking device which is resistant to external external influences, in particular to vibration and / or shock effects or magnetic effects, and which ensures reliable functioning.
  • the solution according to the invention is based on an analysis of the mechanical processes that take place when a locking element is opened due to vibrations and / or shocks.
  • the blocking element is preferably set in resonance oscillation, the necessary restoring forces being exerted by its attachment to the motor.
  • parasitic forces act intermittently on the blocking element and on the motor.
  • Mechanisms can now take effect which favor movement of the blocking element in one direction and hinder it in the opposite direction, in the manner of a council.
  • Such mechanisms can arise through asymmetrical damping, feedback from other vibrating elements, etc. They can cause the locking element to move in one direction during the external action, in the worst case towards the "exposure", i. H. towards the position in which it releases the locking cylinder.
  • a sufficiently large number of parasitic force surges is therefore sufficient to transfer the blocking element from its blocking position into the open position.
  • a critical force for example the maximum parasitic force occurring during a force surge
  • a moving mass on which a restoring force acts, forms an oscillator with at least one resonance frequency.
  • Such an oscillator can in turn be set into resonance vibrations by excitation with a suitable frequency, the amplitude of which - depending on the damping present - can become very large. Taking advantage of this effect, the locking device could undesirably be opened by external influences.
  • the locking device has at least one electronically controlled locking element, hereinafter simply called “locking element”, with at least one degree of freedom of movement.

  • a rotor and a stator of the locking cylinder can be mutually locked by this locking element. If the locking element is to lock the SchHess cylinder, it should be in a certain first position, hereinafter referred to as “locking position”. the. In a second position, hereinafter referred to as “free position", the locking element releases the SchHess cylinder.
  • the locking device according to the invention has drive means for exerting a worker on the locking element.
  • the blocking element can be reversibly transferred from the blocking position into the free position and vice versa by means of the worker.
  • the locking device has guide means which are connected to the drive means and uniquely determine the position of the locking element at least outside the exposure.
  • the locking device has back-control means which are connected on the one hand to a support which is immovable relative to the stator and on the other hand to the locking element.
  • the back control means exert a restoring force directed away from the free position on the locking element when the locking element is in a vicinity of the free position.
  • the locking element should lock in the vicinity of the exposure.
  • the blocking element can preferably have, in addition to the blocking position and the free position, a third excellent position, the "rest position", in which the back control means exert no force on the blocking element.
  • the rest position the locking element locks the SchHess cylinder.
  • the restoring means exert a restoring force directed away from the free position on the locking element when the locking element is between the free position and the rest position. and that the locking element in the rest position and in the positions between the rest position and the free position locks the SchHess cylinder.
  • the exposure is preferably arranged in such a way that the largest possible worker and / or the greatest possible distance, i. H. the greatest possible energy is required to transfer the blocking element from the rest position into the open position. Then it is practically impossible to open the locking device only with the action of vibration and / or shock, without actuating the drive means.
  • the drive means are capable of exerting a worker on the locking element which is greater than the respective restoring force.
  • the blocking position is arranged in such a way that the greatest possible distance is necessary to transfer the blocking element from the blocking position to the free position.
  • the blocking element can perform linear translations along a certain route
  • the free position is preferably at the first end of this route, the blocked position at the second end of the route and the rest position in the middle of the route.
  • the push-back force always acts towards the middle of the route, that is to say towards the rest position, where, according to the invention, the locking element is already locking.
  • the rest position can coincide with the blocking position or be completely absent.
  • the position of the locking element is clearly specified by guide means in order to avoid freely oscillating masses. ben. At least in an environment of the exposure, a backward control force is exerted on the blocking element which is opposite to the parasitic forces.

  • FIGS. 2 and 3 show a special case because the rest position X Q lies in the middle between the blocked position x s and the free position x F. Of course, this does not have to be the case.
  • the locking device according to the invention could, for example, be designed such that the rest position X Q is beyond the blocking position x s , ie XQ ⁇ x s .

Abstract

Ce dispositif de verrouillage d'un cylindre de fermeture (12) comprend un élément de blocage (2) à commande électronique qui dans une position de blocage (xS) bloque un rotor (1) par rapport à un stator (6) et dans une position de libération (xF) libère le rotor (1). Une force (FA) exercée sur l'élément de blocage (2) par des moyens d'entraînement (9) permet de faire passer l'élément de blocage (2) de la position de blocage (xS) à la position de libération (xF) de manière réversible et vice-versa. Des moyens de guidage (52-57) reliés aux moyens d'entraînement (9) déterminent clairement au moins hors de la position de libération (xF) la position de l'élément de blocage (2). Lorsque l'élément de blocage (2) est entre la position de libération (xF) et une position de repos (x0), des moyens de rappel (3) exercent une force de rappel (FR) sur l'élément de blocage (2) de façon à l'éloigner de la position de libération (xF). Dans la position de repos (x0), ainsi que dans les positions situées entre la position de repos (x0) et la position de libération (xF), l'élément de blocage bloque le rotor (1). Ce dispositif de verrouillage résiste aux effets indésirables de vibrations et/ou de chocs extérieurs, ainsi que de champs magnétiques.
