Abstract

PURPOSE: To improve the safety at the time of opening and closing the door of the peephole by a method wherein a locking mechanism consisting of a holder, a pin and a cam is provided at the lug of the door of the peephole for the furnace such as boiler or the like in order to lock an operating handle to the aspirating air jetting position when the door is open.
CONSTITUTION: When the door 6 is turned to the open position after the operating handle 15a being turned to the position capable of opening the door 6, the cam 21 is also turned and yet the holder 24 is turned together with the door 6 by the energizing force of a spring 22. At this time, the holder 24 is turned further until a stopper (not shown) operates so as to release the engagement between the pin 25 and the cam 21. The holder 24 turned to the position perpendicularly intersecting with the peephole main body fits to the operating handle 15a in the aspirating air jetting state in order to lock the handle 15a. This also results that the operation of the operating handle 15a is impossible unless the door 6 is operated to be closed. Accordingly, the safety related to the opening and closing of the door can be improved.
