Definitions

  • the invention relates to an electromagnetically controlled locking lock with a bolt operated via a handle with an electromagnet acting as a holding magnet, a locking lever provided with a magnet armature, a control lever coupled to the locking lever and an interrogation bar operated by the handle, the tour pin of which moves against a projection of the control lever.
  • the control lever only tilts into the release position when the armature of the locking lever is held.
  • An electromagnetically controlled lock according to the preamble of claim 1 with a codable release command and a handle for actuating the bolt has been described in EP 0228027.
  • This lock has an electromagnet that only performs a holding function, the armature of which sits on a locking lever.
  • This locking lever is connected via a spring and a mandrel to a control lever that locks or releases the main bolt.
  • the torques for actuating the main bolt and the locking and control lever are applied via a handle, so that the electromagnet only needs to hold the offered anchor. Since there is no need for any lifting work, the magnet designed for low voltage can be kept very light and inexpensive.
  • the invention is concerned with the improvement of such locks in holding magnet technology.
  • no adjustment forces should be able to be exerted on the bolt during the query function. It is therefore a matter of uncoupling the bolt from the handle during the query movement.
  • the lock housing 1 is indicated by dash-dotted lines.
  • the main bolt 2 is slidably mounted in it, the head 2a of which emerges from the housing 1.
  • a clutch disc 3 is rotatably mounted, which has a square opening 3a in the center for a handle. This square opening is expanded to a key channel 3b, so that a double-bit key can be inserted after removal of the handle in order to reach an emergency opening lock arranged behind the lock. This should then come into operation when the electromagnetically controlled locking lock fails.
  • the clutch disc 3 carries on its upper side a cuboid eccentric 3c which engages in a driving curve 2b of the main bolt 2.
  • a mandrel 3d is provided which engages in the control curve 4a of an interrogation bolt 4.
  • This bolt is slidably mounted transversely to the longitudinal axis of the housing 1. It bears on its upper edge a tour pin 4b which engages in a control lever shown in Figs. 4-6.
  • the interrogation bar also has a control pin 4c and a control slot 4d.
  • An elongated hole 4e is used to guide the bolt in the housing 1.
  • the driving curve 2b of the main bolt 2 consists of a first arc 2b1, a groove 2b2 and an arc 2b3.
  • the bolt 2 In the closed position, the bolt 2 is blocked by the rectangular eccentric 3c. If you turn the handle to the right, the eccentric 3c moves along the arc 2b1 and over the groove 2b2 until the eccentric abuts the arc 2b3.
  • the mandrel 3d on the underside of the clutch disc transmits a torque to the interrogation bar 4.
  • parts 2, 3, 4 assume the position shown in FIG. 2.
  • the handle can be turned further to the right until the position according to FIG. 3 is reached.
  • the eccentric 3c is fully immersed in the groove 2b2 before sliding along the circular arc 2b3.
  • the bolt 2 is blocked by the eccentric 3c.
  • a control lever 6 is mounted on a mandrel 5 fixed to the housing, the cutting edge 6a of which is provided as a projection and faces the tour pin 4b.
  • a curved control slot 7b is important for the interrogation process.
  • An electromagnet 9 faces armature 7a.
  • the held magnet armature acts as a fulcrum.
  • the control pin 4c presses the locking lever 7 and with it the control lever 6 to the left, as a result of which the tour pin 4b can pass the cutting edge 6a.
  • a second electromagnet can be installed, which also acts on the locking lever.
  • a double-bit lock can be arranged under the lock described.
  • the bolt then actuates a slide in the lock via a pin, which mechanically blocks the magnet armature in the system position and thus simulates an opening command.
  • a combination lock could also replace a double-bit lock for emergency opening.
  • the lock described is ideal for series use in all high-quality wallets and armored cabinets, because it is cheaper to manufacture than previously known locks and at the same time offers greater security against manipulation.
