DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of an electric lock device according to the present invention will be described below with reference to FIGS. 1 to 4.

FIG. 1 is a system diagram showing an electric lock device according to the present invention. The electric lock 1 to be installed is equipped with a deadbolt 1a that can move forward and backward into the door frame B by remote control, and the deadbolt 1a can be moved forward and backward from the operating base unit 2 or the secret switch 3, which corresponds to the operating unit, as in the conventional example. The same is true.

FIGS. 2 to 4 are explanatory diagrams of the chain lock mechanism of the electric lock 1, and FIG. 2 shows the chain lock head C1 slipping out of the locking groove 1c and entering the chain lock unlocked state. Figure 3 shows the chain lock locked state with the chain lock head C1 locked in the locking groove 1c, and Figure 4 shows the chain lock head C1 slipping out of the locking groove 1c and locking the chain. This shows the state immediately after the lock is unlocked.

The electric lock device according to the present invention is different from the conventional example in that the electric lock 1 is provided with a locking groove 1c in which the chain lock head C1 of the chain lock C can lock. A trigger 1d is provided at the lower end of the locking groove 1c to prevent the chain lock head C1 from slipping out of the locking groove 1c due to the weight of the chain lock head C1 and the weight of the chain C3 when locked in the locking groove 1c. In particular, a magnet C5 is provided on the tip surface of the chain lock head C1, and when the chain lock head C1 locked in the locking groove 1c is prevented from slipping off by the trigger 1d, the magnet C5 faces the locking groove 1c. A reed switch 1e corresponding to a sensor is embedded in the side surface of the main unit 2, and the chain lock can be unlocked by rotating the trigger 1d by remote control of the operating unit 2a of the main unit 2 to open the lower part of the locking groove 1c. What I did, secret switch 3
It is also possible to set a chain lock password to open the lower part of the locking groove 1c by rotating the trigger 1d by remote control, and the chain lock lock/unlock status is displayed on the status display section 2b of the main operating unit 2. This is what we have made possible.

The chain lock head C1 has a small cylindrical shape with a groove C8 along the center outer periphery. A chain C3 is connected to one end surface of the chain lock head C1, and a chain C3 is connected to the other end. A small disc-shaped magnet C5 is fixed to the end face. Also, the locking groove 1c is the groove C
It is like cutting out a steel plate with a thickness slightly thinner than the width of chain lock head C1, and the width of locking groove 1c is wider than the part narrowed by groove C8 of chain lock head C1, but it is similar to that of chain lock head C1. It is formed narrower than the cylindrical portions at both ends. The lower part of the locking groove 1c is largely opened.

Therefore, in order to lock the chain lock head C1 in the locking groove 1c, the chain lock head C1 is raised so that the groove C8 of the chain lock head C1 is aligned with the lower end of the locking groove 1c. Then, the normal locking groove 1c
The trigger 1d that closes the lower end of the chain lock head C1 rotates clockwise around the rotation axis 1f (in the X direction in Fig. 2) due to the upward force of the chain lock head C1.
1 can move up the locking groove 1c. When the chain lock head C1 finishes passing the tip of the trigger 1d, the trigger 1d rotates to the left (in the Y direction in FIG. 2) and locks into the locking groove 1.
Close the bottom end of c. Therefore, chain lock head C
1 from the hand, the chain lock head C1 does not slip out of the locking groove 1c, and the chain lock is locked (Fig. 3
). Also, the magnet C5 is the reed switch 1
Since the reed switch 1e is close to the reed switch 1e, the reed switch 1e is turned on. Then, in response to the ON signal of the reed switch 1e, a chain lock locked state is displayed on the status display section 2b of the main operation unit 2.

To release the chain lock, operate the chain lock from the operating section 2a of the main operating unit 2, the operating section 3a of the secret switch 3, or the additional operating unit 4. Then, the trigger 1d is rotated to the left (in the Y direction in Fig. 2) by an electric signal from the main operating unit 2, and the trigger 1d is rotated to the left (in the Y direction in Fig. 2) to engage the locking groove 1.
Open the lower end of c and use the weight of the chain lock head C1 and the weight of the chain C3 to close the chain lock head C1.
slides off from the locking groove 1c, and the chain is unlocked (
4). Then, since the magnet C5 is separated from the reed switch 1e, the reed switch 1e is turned off, and the chain lock unlocked state is displayed on the status display section 2b of the operating master unit 2. Then, after a while (about 10 seconds), the electrical signal from the operating base unit 2 will stop, so
The trigger 1d is rotated clockwise (in the X direction in FIG. 2) and returns to the state shown in FIG. 2 in which the lower end of the locking groove 1c is closed again.

As described above, the electric lock device of the present invention can remotely unlock the chain lock and lock the chain lock by hand, and furthermore, the chain lock locking/unlocking state can be known from the status display section 2b of the operating base unit 2. .
