  • Patent number: 6913299
    Abstract: The present invention relates to a locking device for doors with mortise sashlock and remote-controlled door opener or pull or push plates, intended to be openable without being influenced by the spring bolt. The invention is characterized in that the lock also comprises a stop (6) to achieve a blocking position for the spring bolt (3), which stop in closed position, with the dead-bolt in locking position keeps the stop in inactive position, and with the dead-bolt in unlocked position releases the stop to a position where, in cooperation with the spring bolt (3), it keeps the door closed.

  • Patent number: 6179351
    Abstract: The present invention relates to a locking device with movable indicator (4, 5) for sensing the “door closed” or “door open” position of a dead-bolt, provided with a pivotably journalled rotating cam (2) (securing plate) intended to be moved between open and locked position by the released dead-bolt (8). The invention is characterized in that the rotating cam (2) and the indicator are mutually connected by means of a spring, e.g. a tension spring (1) arranged in closed, locking position to produce a force component in the closing direction of the rotating cam, and upon removal of the dead-bolt (8) from the rotating cam, i.e. when the door is opened by means of the indicator, to be displaced in relation to the centre (3) of rotation of the rotating cam so that a force component is obtained in opening direction and the rotating cam is turned to opening position by a snap action of the spring.

  • Patent number: 5195792
    Abstract: A locking device for doors and the like comprising a housing (1) containing a securing plate (8) and ratchet means (19, 20) cooperating therewith to optionally retain the securing plate in locked position. The securing plate is pivotable about a spindle (10) and arranged to be moved between open and closed position by the bolt and to remain in one or other of these positions. According to the invention the device also includes an indicator in the form of a cam (11) with a pin, designed to cooperate with the securing plate in sensing the position of the bolt in relation to a limit breaker or the like when the securing plate is in closed position.
