Claims

[Claims for Utility Model Registration] (1) A rotating body 9 that rotates when locked and unlocked is provided inside the outer cylinder 7 with a flange 7a protruding from the outer periphery of the outdoor end. A lock member 1 is provided with an operating rod 10 that protrudes toward the indoor side from 7, and a lock mechanism that has a flange 11a protruding from the outer periphery of the indoor end and that is slidably fitted in the indoor portion of the outer cylinder 7 in the axial direction. It has a main body 11, and this main body 11
A lock member that forms an engager receiving space 11f at the indoor end of the lock mechanism body, and interlocks with the operating rod 10 through an operating member 12 into which the operating rod 10 is slidably inserted into the lock mechanism main body 11. 16 and a push-out member 13, and engagers 21 and 22 at both ends of the chain body 16.
The chain 4 which is connected to each other, the chain receiving seat 5 which is removably engaged with the engager 21 at one end, and the outer cylinder 7 and the lock mechanism main body 11 are each tightened in the axial direction at a plurality of positions in the circumferential direction. When the lock member 1 is locked, the engager 20 at the other end is inserted into the engager receiving space 11f of the lock mechanism body 11 from the indoor side and engaged with the lock member 16, and the lock member 1 is The locking member 16 and the engaging element 20 at the other end are disengaged by rotation of the operating rod 10 due to unlocking, and the engaging element 20 is pushed out from the locking mechanism main body 11 toward the indoor side by the pushing member 13. A door chain device characterized in that the door chain device is configured to push out the door chain. (2) The chain 4 has a non-circular engaging portion 21a on the engaging member 21 at one end of the chain body 19, and a circular engaging portion 20a on the engaging member 20 at the other end,
The chain receiving seat 5 is connected to the engaging portions 21a and 20a.
An engaging portion 21a is provided at one end of the narrower elongated hole 5d.
, 20a and slightly larger holes 5g and 5f are overlapped to form an entrance/exit portion 5e, and two chain receiving seats 5, 5 are attached to the indoor side surface of the door 6 and the vertical frame 25 of the door frame into which the door 6 is fitted. Each fixed claim
The door chain device described in (1).
