Abstract: Disclosed is a mortise lock having a latch bolt serving as a dead bolt.

Abstract: Disclosed is a locking device which comprises a housing, and a cylinder device rotating within the housing, wherein the housing is provided with a protrusion therein to prevent the cylinder device from being rotated, and the cylinder device includes a motor, a cylinder receiving the motor, a tilting mechanism located at the front of the cylinder, having an upper portion tilted to be fixed to the protrusion of the housing by forward rotation of the motor and a recess released from the protrusion of the housing by reverse rotation of the motor, and a locking plate adapter fixed to the tilting mechanism, and a locking plate fixed to the adapter.

Abstract: A door lock system for locking and unlocking a door, which ensures a normal operation of a driving motor even if interference occurs in a locker while locking and unlocking operations are performed, by delivering a rotation force of the driving motor to the locker through a torsion spring. The door lock system includes: a driving motor which rotates clockwise and counter-clockwise with a predetermined quantity of rotation in response to a door locking signal and a door unlocking signal, respectively; a locker which locks and unlocks a door while rotating by receiving a driving force of the driving motor; and a rotating gear group which has an upper rotating gear that is disposed between the driving motor and the locker and delivers a rotation force, a lower rotating gear, and a torsion spring.

Abstract: Disclosed is an electrical lock apparatus in which protrusions are formed at constant angles in a key head of a key provided with a chip and grooves are formed in an input socket to allow the protrusions to be inserted into the input socket, whereby the input socket can be rotated by turning the key inserted into the input socket. In an electric lock apparatus including a key having a key head provided with inner and outer terminals of a hemispherical shape, and an input socket into which the key head is inserted, having grooves provided with terminals being in contact with the inner and outer terminals of the key head, the electric lock apparatus comprises protrusions formed to surround the key head, and grooves formed at the grooves of the input socket to allow the protrusions to be respectively inserted thereinto, whereby the input socket is rotated as the key is rotated in a state that the key head is inserted into the input socket.

Abstract: Disclosed is a hub locking apparatus for a mortise lock assembly, in which a motor is driven by an externally input electrical signal to control a locking member that binds a hub and is located to be automatically unlocked in case where the motor is destroyed by fire. In a mortise lock assembly including a hub rotating along with a rotary ring connected to a handle, opening a door by retracting and releasing a latch bolt from a door frame in accordance with rotation of the hub, a hub locking apparatus for the mortise lock assembly comprises a locking member preventing the hub from being rotated when one end is fitted into a groove of the hub and allowing rotation of the hub when the one end is released from the groove, a pivot member joined with the locking member to pivot the locking member, and a weight body rotating the locking member using its weight so that one end of the locking member is detached from the groove of the hub to freely rotate the hub.

Abstract: Disclosed are a digital apparatus operating using external power and a method for controlling the digital apparatus. The digital apparatus includes a power supply for supplying power, a one-wire interface for determining if an input signal is a reset signal, a ready signal, a read signal or a write signal, the one-wire interface being connected to the power supply, an oscillator for providing a clock signal to the one-wire interface, a controller for performing a reset operation, a ready operation, a read operation or a write operation according to determination results of the one-wire interface, a RAM and a ROM for storing data, a timer for providing time information, and a RNG for encrypting data.

Abstract: Disclosed is a locking apparatus having a latch bolt separated from a cylinder. The locking apparatus includes a housing, a cylinder rotating within the housing, a slider forwarding or reversing along a shaft direction of the cylinder, a latch mechanism disposed in front of the slider and fixed to the slider when the slider forwards but released from the slider when the slider reverses, and a means for forwarding or reversing the slider. Thus, since the locking apparatus has a simple structure, it has an advantage in that it can be replaced with the conventional locking apparatus having a complicated structure.
