  • Patent number: 4656850
    Abstract: An electric lock comprising a solenoid which has a permanent magnet for attracting a plunger and an electromagnetic coil which is positioned adjacent the permanent magnet so as to control the magnetic flux of the permanent magnet. A cam member which has a cam surface formed at one end thereof engages an engaging pin when a bolt operating member is rotated so as to lock the electric lock so that an engaging rod is forced to move in the direction opposite to the direction in which an engaging bolt is biased, the other end of the engaging rod being connected to the plunger of the solenoid. A positive voltage application unit responds to an unlocking signal so as to temporarily cause a current to flow through the electromagnetic coil in such a way that the flux produced by the electromagnetic coil cancels the magnetic flux produced by the permanent magnet.

  • Patent number: 4625848
    Abstract: Electrically-controlled and manually-actuatable lock devices are provided which can be attached in a simple manner to doors of all types. Given remodeling of existing doors, the cylinder lock present in the respective door can remain. The lock device converts a rotational motion introduced at the outside of the door by the turning of a knob, the rotational motion being conducted to the inside of the door below the lock, into a rotational motion of a cam of a cylinder lock and thus allows a traditional lock to be opened and locked. The rotational motion initiated from the outside is connected to the lock cylinder with the assistance of an electromagnetic coupling device that, in turn, actuates a mechanical coupling device. The electromagnetic coupling device is essentially designed without an air gap. This particular provision enables its operation with very low electrical energy. The lock device can therefore be supplied with electrical energy from very small batteries for years.
