Emergency Release Patents (Class 70/274)
  • Patent number: 8866643
    Abstract: In a rotation input device, a planetary carrier, connected to an operation knob, rotatably supports a planetary gear which meshes with an outer teeth row provided for a sun gear, to which an output shaft is secured, and also meshes with an inner teeth row provided for an outer gear. A plunger provided for the sun gear is in elastic contact with a recess cam provided for the outer gear. A solenoid unit prevents rotation of the outer gear in accordance with an output of a magnetic sensor which faces a magnet provided for the output shaft.

  • Patent number: 4944170
    Abstract: The mechanism comprises a bar (8) slidably mounted in a channel (18) which can be obstructed by a sliding member (11) of an electromechanical latching unit in accordance with a preset time-schedule.The device described enables the time ban to be lifted by means of two pivotal elements (43, 52) that are normally not coupled to one another, one of them being positionable in the path of travel of the bar (8) of the mechanism so as to be actuated thereby when the mechanism is moved in an opening direction. The two pivotal elements are associated with transmission means (50, 57) which are actuated when a breakdown is detected in order to lock the two pivotal elements together. The electromechanical latching unit can then be made inoperative manually by actuating the mechanism of the locking system in an opening direction.

  • Patent number: 4137738
    Abstract: A time lock usable with a lock mechanism having a bolt displaceable along a path for opening a door has a housing which is fixed adjacent the path and in which a keeper is vertically displaceable between an uppermost blocking position, a lowermost unblocking position, and an intermediate position. A clockwork in the housing displaces a lock slide horizontally from a holding position wherein a recess in this lock slide is out of alignment with a dog pivoted in the housing into a freeing position with the recess and dog aligned after elapse of a predetermined interval of time. This locking dog is carried on a locking pawl which is connected via a shortenable link to the vertically displaceable keeper. When the clockwork displaces the lock slide into the freeing position the keeper automatically drops into the intermediate position, with the dog entering upwardly into the recess in the lock slide.
