Definitions

  • the present invention relates to a locking device for doors, intended for connection between the dead-bolt of the door and its drive means (door-frame or rotating cam, such as an electrical strike plate).
  • the locked position shall be firm and unlocking shall not be made more difficult, for instance when a crowd of people are pushing towards the exist, thereby unintentionally preventing its opening.
  • the object of the invention is a solution of these and other similar problems, and is characterized in that a hinged arm is connected to the dead-bolt or its extension, a wheel or pin being arranged at the other end of the arm and designed to tumble into a recess in a pivotable cam- disc upon turning of the cam-disc, and also to be disengageable from this recess, whereupon the cam-disc in the latter case is arranged to block the dead-bolt and upon tumbling into the recess release it, and also that the dead-bolt has an inclined surface designed, upon pressure against the dead-bolt, to assist in the opening process.
  • the arrangement of dead-bolt and drive means normally provides reliable locking and unlocking and the inclined surface assists in ensuring opening even in emergency situations arising out of pressure against the door and thus against the dead-bolt, since a force component is obtained in opening direction of the dead-bolt.
  • the object of the invention can be used on double doors by applying it on the passive door, where pressure is obtained from a door-frame.
  • the drive means comprises a spring bolt actuated by a door-frame.
  • the invention can also be applied on a single door, such as a fire-door, where the pressure is obtained from a rotating cam, e.g. an electrical strike plate.
  • a rotating cam e.g. an electrical strike plate.
  • the drive means is in this case an electro-magnet, and the pressure is obtained from a rotating cam.
  • cam-disc is arranged to be turned either with or against spring force and the same cam-disc is provided with a blocking protrusion, designed to cooperate in locking position with a locking surface in the extension of the dead-bolt.
  • a lock having a dead-bolt (1) designed for engagement in a door-frame and to lock the passive door in double doors to a door-frame.
  • the dead-bolt (1) is shaped with a bevelled surface (3) designed, upon pressure against the door, to produce a force component in opening direction.
  • the dead-bolt has an extension (5) to which an arm (6) is hinged.
  • a wheel (7) or pin for engagement in a recess (8) in a swivel cam-disc (9) is arranged at the outer end of the arm
