Definitions

  • the invention relates to a device for blocking the rotation of a cylinder core in the cylinder housing of a lock cylinder.
  • Electromagnets are often used here, the armatures of which engage in the cylinder core. Such electromagnets not only require sufficient installation space so that they are usually housed in the cylinder housing, but the energy requirement is also comparatively large, a distinction having to be made between designs which are excited during blocking and those which are only used to release the blocking must be excited.
  • the invention has for its object to provide a device of the type mentioned in such a way that it not only requires a very small amount of space, but also manages with minimal energy consumption.
  • a recess facing the cylinder core is provided in the cylinder housing, a blocking strip which can be pushed back behind the dividing line cylinder housing / cylinder core can be brought into engagement with the recess, with the locking bar, rolling or sliding elements interact with one another
  • the rolling or sliding elements together with the locking bar can be pressed radially out of the cylinder core into the recess, on the side facing away from the cylinder housing, the locking bar is fixed with a
  • a blocking mechanism is arranged in the cylinder core, which consists of a Lavet motor, with a coil, a stator, a
  • Rotor and a locking part connected to it and engageable with the locking bar wherein the locking part can be brought under the action of the magnetic field of the coil into a stable position that prevents the locking bar from moving back and a momentary position that allows the locking bar to move back.
  • the core component of the solution according to the invention is a Lavet motor.
  • This consists of three basic components, namely the stator, the coil arranged thereon and a rotor on which a permanent magnet is arranged.
  • the permanent magnet has only one direction of polarization, so that there are two stable positions for the rotor. These lie opposite each other at an angle of 180 °. In these positions of the rotor, the torque is zero. If you turn the rotor by 90 °, the torque is also zero, but these positions are unstable. If the rotor is moved very little, the rotor immediately turns to the next stable position. By applying a current to the coil, a magnetic field is built up and this causes the rotor to be aligned accordingly, e.g. Deflection of the rotor from the previous stable position to another stable position.
  • FIG. 1 is a partially sectioned view of the blocking mechanism
  • FIG. 2 is a perspective view
  • Figure 3 shows a detailed view.
  • the locking cylinder consists of the cylinder housing 1 and the cylinder core 2.
  • the locking mechanism which prevents the cylinder core from rotating in the cylinder housing, is accommodated in the cylinder core and consists of the locking block 6, a spring leaf 7 (a spring rod or the like can be used instead of the spring leaf) and rolling or sliding elements which are in engagement with it under the pressure of springs 5 and which are designed as balls 4 in the present case.
  • the Lavet motor whose coil is designated 10, stator 11 and rotor 9.
  • stator 11 whose coil is designated 10
  • rotor 9 there is a locking cam 8 which can be brought into engagement with a recess on the locking bar 6.
  • the locking bar can be moved out of the recess in the cylinder core or its displacement is prevented, so that the cylinder core cannot be rotated relative to the surrounding cylinder housing.
  • the blocking position he uses stable positions of the rotor, while a rotation of the rotor under the action of the magnetized coil by a little more than 90 ° leads to the release of the blocking bar. All that is required for this rotation is a short pulse of approximately 10 ms. What is important is the correctly dimensioned duration of the pulse and the correct direction of the magnetic field.
  • By rotating the rotor more than 90 ° it tries, without current, to turn to the next position, rotated by 180 ° from the original position.
  • By limiting z. B. by a mechanical stop however, it is held in a stable position rotated by more than 90 ° to the original position.

Abstract

L'invention concerne un dispositif pour empêcher la rotation d'un noyau de cylindre dans la cage de cylindre d'un cylindre de fermeture, comportant les caractéristiques suivantes: dans la cage de cylindre (1) est ménagé un évidement (3) tourné vers le noyau de cylindre (2), une barrette de blocage (6) pouvant être reculée derrière la ligne de séparation cage de cylindre/noyau de cylindre peut être amenée en prise avec l'évidement (3), des éléments de roulement ou de glissement (4) coopèrent avec la barrette de blocage (6), lesquels peuvent, par une circonférence partielle, faire saillie dans l'évidement, sous l'action de ressorts (5), les éléments de roulement ou de glissement (4) peuvent être poussés dans l'évidement (3), conjointement avec la barrette de blocage, radialement depuis le noyau de cylindre (2), sur le côté opposé à la cage de cylindre, la barrette de blocage (6) est solidarisée avec une lame de ressort (7) sur laquelle s'appuient les éléments de roulement ou de glissement côté cage de cylindre, sur le côté de la barrette de cylindre (6) opposé à la cage de cylindre, un mécanisme de blocage (8, 9, 10, 11) est disposé dans le noyau de cylindre (2), ledit mécanisme de blocage est constitué d'un moteur Lavet comportant une bobine (10), un stator (11), un rotor (9) et une partie de blocage (8) reliée avec ce dernier et pouvant venir en prise avec la barrette de blocage (6). Cette partie de blocage (8) peut être amenée, sous l'action du champ magnétique de la bobine (10), dans une position stable empêchant un mouvement de recul de la barrette de blocage (6), et dans une position momentanée autorisant le mouvement de recul de la barrette de blocage (6).
