At this time, the stationary motor (6) is in the stopped state until the dead bolt (16) is retracted into the interior of the electric box (10a) to stop and then apply a separate next signal to the stationary motor (6). Regardless of the appearance of the latch bolt 46, the dead bolt 16 is also retracted to maintain a stopped state.

On the other hand, the switch lever 53 formed below the latch bolt 46 is formed in the inclined surface 54, the protruding portion of the electrical box (10a) is formed in the inclined surface 54 is formed on the door frame 60 It is pushed to the periphery of the lever groove 63 and retracted into the interior of the electrical box 10a. When the lever groove 63 is separated, the lever spring 56 is installed to the rear of the switch lever 53. It protrudes out of the electric box 10a.

As described above, the switch lever 53 has a switch lower terminal 51 by a lever rod 55 formed in the middle of the switch lever 53 while repeating the appearance of the door as shown in FIGS. 8A and 8B. ) Repeatedly controls the rotation of the stationary motor (6) by giving a signal to the switch (50).

Therefore, as described above, the electric well 10 is released and the door is slightly opened (the latch bolt 46 and the switch lever 53 protrude), the door is completely opened and the inside handle 8 is held after entering the room. When the door is closed, the latch bolt 46 and the switch lever 53 formed with the inclined surface 54, which are formed in a half moon, are pushed back into the electric box 10a while being pushed against the door frame 60, and the door is completely When closed, the latch bolt 46 and the switch lever 53 protrude again and are caught by the dead groove 61, the latch groove 62, and the re groove 63 formed on the door frame 60.

The latch bolt 46 is protruded to the outside of the electrical box 10a by the hinge spring (44) fitted to the hinge shaft (41b), the locking rod 43 formed on one side of the latch hinge (40) It stops and stops at the latch bolt 46 to prevent it from protruding further.

When the door is closed as described above, the switch lever 53 is retracted into the electrical box (10a) while the lever rod 55 touches the switch lower terminal 51 to give a signal to the switch 50 In response to the signal, the switch 50 gives a reverse signal to the reverse motor 6 so that the reverse motor 6 reverses and the dead cam 11 on which the dead rod 12 is rotated reversely.

As the dead cam 11 is rotated in this way, the dead plate 14 is advanced by the dead rod 12 so that the dead bolt 16 coupled to the front of the dead plate 14 is the electric box 10a. By protruding to the outside of the dead groove 61 formed in the door frame 60 is locked, the first locked state is to correct the electric well 10.
