EMERGENCY ENTRANCE WINDOW EQUIPPED WITH HANDLE DEVICE

PROBLEM TO BE SOLVED: To provide an emergency entrance window equipped with a handle device which is provided with a lock structure, can unlock the lock structure by only an operation of an external handle, and can further unlock the lock structure to promptly open a paper sliding door. SOLUTION: The emergency entrance window is equipped with an internal and external handles 5, 6 and the lock structure 7. The handle shaft 33 of the external handle 6 and the rock shaft 67 of the lock structure 7 are arranged so as to face each other while holding a conversion mechanism between, allowing both shafts 33, 67 to be alternatively connected to the conversion mechanism. The external handle 6 is provided with a cam mechanism for performing the retractable operation of the handle shaft 33. The lock structure 7 can be switched by a key body 68 either to a locked state or to an unlocked state. The locked lock shaft 67 is forwardly operated to be interlocked by the conversion mechanism. The handle shaft 33 is moved forward by the first-half rotation movement of the external handle 6 to release the interlocked state between the lock shaft 67 and the conversion mechanism, and also to interlock them simultaneously. A slide frame 4 can be slid by the latter-half rotation movement of the external handle 6 to release the lock structure. COPYRIGHT: (C)2010,JPO&INPIT
