摘要： PURPOSE: To allow a person to open a door easily, when the person carries an item with himself or herself by permitting the door to be opened without rotating a handle by pulling an inner handle or pushing an outer handle so as to disengage engagement of a latch bolt. CONSTITUTION: An outer handle 1 having a tumbler lock 3 and an inner handle having a rotary knob 9 are connected by a guide base part 4 having an inclined surface part 76. Contact with a latch bolt 6 having a return spring 53 is made at the inclined surface part 76. By pulling an inner handle 2 or pushing the outer handle, the engagement of the latch bolt 6 is disengaged so as to make the door opened. If the tumbler lock 3 is locked or the rotary knob 9 is locked, the latch bolt 6 cannot be unlocked, even if the outer handle 1 is pushed. Even in this case, the latch bolt can be unlocked by pulling the inner handle 2. With this constitution, operability and burglar proof properties of the door are improved.
