Abstract:
PURPOSE: A door latch device is provided to prevent a collision between a user and a hinged door opened by an opponent when the user opens the door or stands around the door. CONSTITUTION: A door latch device includes a latch unit (100), a connection driving unit (300), a first slide unit, and a second slide unit. The latch unit includes a first latch bolt (110a) and a second latch bolt (110b) possible to move forward and backward. The connection driving unit includes a first knob shaft (340a) and a second knob shaft which are rotated by receiving power from outside; a first slide hooking bracket (310) converting a rotational motion of the first knob shaft into a linear motion; and a second slide hooking bracket converting a rotational motion of the second knob shaft into a linear motion. The first slide unit connects the first slide hooking bracket to the first latch bolt. The second slide unit connects the second slide hooking bracket to the second latch bolt.
