MORTISE STRUCTURE CAPABLE OF BIDIRECTIONALLY UNLOCKING A DIGITAL DOOR LOCK FOR BEING APPLIED TO A LEFT-HANDED DOOR AND A RIGHT-HANDED DOOR

摘要

PURPOSE: A mortise structure capable of bidirectionally unlocking a digital door lock is provided to offer economic feasibility by being mounted at the right-handed and left-handed doors of a push and pull type door lock.;CONSTITUTION: A latch bolt (10) is protruded to the groove of a door frame for maintaining a door to be closed. A latch operating block (40) tows the latch bolt and unlocks the latch bolt. A latch operating block manipulating part is rotated by an outer operating means and rotates the latch operating block. A rotary power conversion member interlocks with the latch operating block manipulating part for moving and forms a slide surface contacting the latch operating block. The latch operating block manipulating part and the latch operating block independently rotate in the predetermined range of an angle.;COPYRIGHT KIPO 2013
