る。SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a thumb bolt on the indoor side or an outdoor side to make a dead bolt provided in a lock box attached to a door protrude and retract from a front plate. In this final lock, a cam rotatably supported by a lock box is engaged with the dead bolt so that the cam can be rotated by the cylinder lock. The first cam on the indoor side and the second cam on the outdoor side, which are mutually displaceable with respect to each other, have a first cam between the arm piece of the first cam and the arm piece of the second cam.
In order to connect the cam and the second cam to a connected state or a non-connected state, a connecting piece movable along the radial direction of both arm pieces is mounted, and the connecting piece is moved to a connecting position and a non-connecting position. A changeover switch is provided in the lock box so as to be exposed at an opening provided in the front plate, and one end is linked to the changeover switch, and an arc-shaped floating length is formed at the other end. An operating lever having a hole is provided, and an engaging pin is protruded from the connecting piece. The engaging pin is movably fitted into the guide slot of the operating lever, and an arc-shaped guide provided on the lock box. The engagement pin is movably fitted in a locking hole that is continuous with the elongated hole or the guide elongated hole, and the engagement pin is selectively engaged with the locking hole by the operation of the changeover switch, so that the thumb-turn operation can be performed. Is disabled.

る。In order to activate the security device according to the present invention, the upper side of the changeover switch 6 with the door 10 opened is pushed in as shown in FIG. At this time, the actuating lever 7 swings counterclockwise (counterclockwise) in FIG. 5 to connect the connecting piece 5 to the guide groove of the first cam 41 through the engaging pin 51 by means of the floating slot 73 at the other end. Push up along 41b.

れる。In other words, the connecting piece 5 is displaced on the arm 41a of the first cam 41 toward the rotation center axis (FIG. 5).
7), the second cam 42 is disengaged from the first cam 41, while the engagement pin 51 is connected to the guide slot 1 of the lock box.
5 is guided to the locking hole 16 and engaged with the locking hole 16.

１カム４１とは独立して回動できることになる。In this operating state, the first cam 41 is connected via the connecting piece 5 and the engaging pin 51. Since the lock is locked to the lock box 1, locking and unlocking by the thumb turn on the indoor side is impossible, but the second cam 42 disengaged from the first cam 41 rotates independently of the first cam 41. Will be able to move.

勿論である。Therefore, in such an operating state, the occupant or the like can be locked via the second cam 42 with the key inserted into the outdoor cylinder lock when going out (FIG. 8).
Also, it is of course possible to unlock in the same way when returning home.

不正解錠は依然として不能である。Also, at this time, even if the thumb pin is turned by a great force to break the engagement pin 51 by abutment with the edge of the engagement hole 15, the second cam directly linked to the deadbolt 3 is formed. Since the first cam 41 is not in a connected state with respect to 42, the first cam 41 only idles and illegal unlocking by the thumb turn is still impossible.

の効果を奏する。According to the security device of the present locking device according to the present invention described above, the door itself or the window glass provided in the vicinity thereof is broken, and a hand is inserted from there to rotate the thumb turn. Even if the occupants can go out, they can lock the thumb turn so that they cannot rotate, and since the lock of the thumb turn cannot be released unless the door is opened, it is extremely advantageous for crime prevention.
