Unlocking the inward-opening living room door and replacing the Nagasawa GM empty lock

"Request to unlock the interior door. Some people can't move in the living room."

There is a lever that does not work with the latch bolt.I moved to another room and closed the door.However, when I returned to the living room, it seemed like the door had suddenly been locked.A person who cannot move is trapped in the living room.

The tubular body is often damaged, but the latch is not visible from the working side. GAP is less than 2mm.

The door seems to be distorted, and the gap for the swastika tool is not constant.I managed to make a gap with an air bag and unlock it with a special bag tool.

The front carved seal is ATOM.The latch bolt of the disassembled tubular body is a damaged part, so it is difficult to retract.An equivalent product is prepared, but the angle center size of the handle shaft is as large as 8.2 mm.

I prepared a Murakoshi tubular, but it's 8mm, so the existing shaft won't fit.I've tried cutting the shaft with a grinder, but it takes a lot of time.Therefore, change to Nagawasa's GM empty lock.No additional work was required.
