There is a problem that the door cannot be opened because the dead bolt and the latch bolt remain in the receiving bracket of the door frame. For this reason, for example, as shown in Japanese Patent Application Laid-Open No. 9-25746, when an earthquake occurs, the entire lock box having the lock rod is retracted into the door body, and the lock rod remains in the metal fitting of the door frame. Locking devices have been proposed to prevent this.

提供することを目的とする。At the entrance door of a condominium or the like, from the viewpoint of security, the locking member of the chain member fixed to the door frame is manually hooked on the chain receiving bracket on the door side to open the door. , A door lock is installed, and some occupants always wear this door chain. For this reason, even if the door of the door lock is unlocked from the receiving bracket at the time of the earthquake, even if the door is pushed out from the room, the door is not locked even if the door is pushed out of the room when the chain locking member is in the locked state of being hooked on the chain receiving bracket. The opening of the body was restricted by the chain lock, and there was a problem that it was not possible to escape quickly from the room. SUMMARY OF THE INVENTION It is an object of the present invention to provide a door locking device that unlocks a door chain and unlocks a door chain when an earthquake occurs, thereby enabling quick escape from a room.

できる。The chain receiving bracket is provided so as to be rotatable about an axis at one end so as to be able to protrude from the body surface of the door lock so that the end of the groove for locking the locking member is opened. It is good to have composition (claim 3). When the chain receiving bracket rotates and protrudes from the door lock body surface, the end of the groove is opened, so the chain lock is released by the hanging weight of the hanging chain or the opening operation of the door. It can be easily separated from the groove end that has been opened.

ようになっている。As shown in FIG. 2, the operating mechanism 16 is provided in association with the trigger rod 15 and the cam 21, and includes a lever 36, a locking claw 37, a pressing member 38 and the like. One end of the lever 36 is swingably supported by the lock body base frame 10 by a fulcrum shaft 39, the other end is opposed to the protruding portion 30, and a long hole 40 provided in the middle is provided in the locking claw 37. Pin 4
1 is engaged. The locking claw 37 is supported by the lock body base frame 10 so as to be movable in parallel with the trigger rod 15, and is urged forward by a spring 42 provided at the rear end. Pressing member 3
8 is provided on the lock body base frame 10 so as to be able to advance and retreat in a direction substantially perpendicular to the trigger rod 15 and is urged in the forward direction by a spring 43 provided at the rear end. The locking claw 37 has a concave groove 44 with which the tip of the engagement engages, and the tip presses the outer periphery of the cam 21 to advance and rotate the cam 21 when moving forward. The distal end of the pressing member 38 at the retracted position is in contact with the outer periphery of the cam 21 at the rotation position when the dead bolt 14 is in the protruding state.
The cam 21 is driven to rotate to a position where the cam point 4 surely crosses the dead point to the retreat side. Further, when the cam 21 is rotated in the reverse direction to project the dead bolt 14, the cam 21 retreats the pressing member 38 during the rotation. Since the locking claw 37 is urged by the spring 42 in a state where the action force of the lever 36 is removed, the locking claw 37 automatically engages with the concave groove 44 when the pressing member 38 retreats. .

In (c), when an earthquake occurs and the earthquake detecting means generates an unlock signal, the following operation is performed. First, the solenoid 47 of the unlocking signal response unit 17 is
5 is temporarily retracted and disengaged from the recess 48, whereby the trigger rod 15 performs a protruding operation. The projecting operation of the trigger rod 15 is stopped by the stopper 31 being in contact with the groove end 34 of the notch groove 32 and the amount of protrusion is regulated. Since the guide roller 28 at the distal end pushes the force point portion 55 of the lever member 50 by the protrusion, the lever member 50 swings, and the action point portion 56
Is pushed back against the spring 18. The retracted position is, as shown in FIG.
This is the position that matches the surface position of. The advancement of the trigger rod 15 causes the lever member 50 to swing, and at the same time, the protrusion 30
Swings the lever 36 of the operating mechanism 16 and the protrusion 75 swings the lever 74 of the interlocking means 58.

Since the cam 21 is rotationally driven by the advance of the pressing member 38, the dead bolt 14 is retracted to the retracted end. Further, since the locking pin 45 of the unlocking signal responding unit 17 is temporarily retracted and opened by the solenoid 47, the locking pin 45 contacts the outer peripheral surface of the trigger rod 15 by the spring 46 and stops. The swing of the lever 74 of the interlocking means 58 causes the locking pin 68 to retreat and release the holding of the chain receiving member 61 as described above, so that the chain receiving member 61 is pushed out by the action of the spring 66 so that the shaft 67 is centered. To protrude to open the end of the engaging groove 64. By opening the end of the engagement groove 64, the locking member 79 can be detached from the engagement groove 64 of the chain receiving member 61 with a small acting force toward the open end of the engagement groove 64, so that the weight of the chain is reduced. , Or naturally by the force acting on the chain member 62 when the door 2 is opened.

When the dead bolt 14 is unlocked from the beginning, the latch bolt 13 is unlocked, and the state similarly becomes as shown in FIG. The state shown in FIGS. 5 and 6 is a state in which the locking rod is unlocked and the door chain 60 is released, so that the door 6 can be pushed and opened as it is. When the door 6 is pushed open, first, the mounting portion 5 of the receiving bracket 3 is moved from a position where the tip of the latch bolt 13 is in contact with the lever member 50.
1 and moves as it is to protrude from the surface of the mounting portion. Guide roller 28 at the tip of trigger rod 15
Immediately after the tip of the latch bolt 13 has moved to the surface of the mounting portion 51, it comes into contact with the opening edge of the recess 48 of the receiving member 3, and the guide roller 28 receives a reaction force and the trigger rod 1
5 is retracted, and the trigger rod 15 that has reached the retracted end is locked by the locking pin 45 of the unlocking signal response unit 17. Therefore, in the door 6 thus opened, the trigger rod 15 is retracted to the position shown in FIG. 2, the dead bolt 14 is retracted to the position shown in FIG. In this state, the chain receiving member 61 is opened and protrudes, and the locking member 79 is detached.
