ABSTRACT:
A one-touch doorlock device having a construction capable of being easily mounted at either a left or right side of a door by a simple manipulation, locking the door only by manipulating the doorknob without any additional manipulation, and outputting speech messages respectively corresponding to locked and unlocked states of the door by use of a microcomputer and a ROM as a speech memory stored with speech messages. The device thus provides easy and convenient doorlock mounting and provides convenience in use to the user. The doorlock device includes door locking mechanism for moving the locking bolt to its locked position. The door locking mechanism has a rotating member operatively connected to the doorknobs in such a manner that the rotating member rotates by a manipulation of the doorknobs, thereby moving the locking bolt between an extended position corresponding to the locked position and a retracted position. The doorlock device also includes lock releasing mechanism for rotating the rotating member in a direction such that the locking bolt moves to its retracted position. The lock releasing mechanism is activated by a signal output from a key input unit, and bolt direction switching mechanism for switching the manipulation direction of the doorknobs between left and right directions in accordance with a door opening direction.
