Abstract

PROBLEM TO BE SOLVED: To dispense with the drilling operation of a fitting hole in an existing header in exchanging a locking release mechanism by divert a hole in a door rail, fixing a door lock SW bracket, and mounting the sliding type locking release mechanism thereon. SOLUTION: To achieve the locking/unlocking from the outside, a working piece 9 to be vertically moved in the slide system with a guide plate 8 as a guide and a working piece holding plate 10 therefor are fixed by fitting bolts 11 to a door lock SW bracket 7 provided with a rotation preventive projecting part 7a engaged in a recessed part of an existing door rail 2. A lock outer bar 11 is inserted from a clearance 3a of a landing hall door 3, and pushed up to slide the working piece 9 arranged on the door lock SW bracket 7 upward and to operate an unlocking lever 5a upward. A locking hook 5c is turned with a rotary shaft 5b as a supporting point, and a notched part provided in a tip part is detached from a locking claw 6a to achieve the unlocking.
