DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disk tumbler lock device for locking a disk-type tumbler by locking it in a receiving hole of a fixed main body.

[0002]

2. Description of the Related Art In a conventional disk tumbler lock device, when a rotor is in a locked position, a predetermined number of disk tumblers are inserted into slots formed continuously in the front-rear direction on the inner surface of a fixed body. By doing so, the rotation of the rotor is stopped at the locked position.

Recently, a burglary has been developed in which a tapping screw is driven into a key insertion hole of a rotor of a lock, the rotor is pulled out together with a screw using a tool such as a nail cutter, and the lock is broken to unlock the lock. In the conventional disk tumbler locking device, since the disk tumbler is inserted into the groove of the fixed body at the time of locking, it cannot resist the pulling out of the rotor, that is, the force in the front-back direction at all. In the lock device, such an unauthorized unlocking is performed only at a slightly unstable portion between the fixed body and the pivot portion of the rotor, and between the rear end portion of the rotor and the fixing portion of the stopper plate. It was impossible to completely prevent it.

[0004]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a disk tumbler lock device which can enhance the resistance to pulling out a rotor from a fixed body and more effectively prevent unauthorized unlocking due to violent destruction. It is to be.

[0005]

The disk tumbler lock device according to the present invention will be described with reference to the accompanying drawings. In the disk tumbler lock device according to the present invention, a fixed main body 2 fixed to a door 1 and housed in the fixed main body 2 will be described. A rotor 3 rotatable by insertion of a key, and a lateral hole 4 penetrating through the rotor 3 in a diametrical direction. And a fixed number of disc tumblers 6 pressed against the outer member 9 and the inner member 1.
0 was separated and configuration, provided independently of each other through the catch holes 7 each disk tumbler 6 in the locking position of the rotor 3 is engaged with the side wall portion of the inner member 10 is partitioned by the partition wall 8, the inner The member 10 is fitted and fixed to the outer member 9.

The front surface of the distal end of each disk tumbler 6 inserted into the receiving hole 7 is provided with a partition wall 8 between the receiving hole 7 and the front.
To prevent the rotor 3 from being pulled out of the fixed body 2.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the illustrated embodiment, the fixed body 2 is constituted by being separated into an outer member 9 and an inner member 10, and the inner member 10 is provided between the members on the side where the disk tumbler 6 is locked when locked. A predetermined number of receiving holes 7 partitioned by partition walls 8
Are provided in isolation, and a continuous slot 11 in the front-rear direction is provided on the side where the disk tumbler 6 is locked when unlocked. The inner member 10 is inserted into the outer member 9 from the front, and two elastic hooks 12 projecting rearward and outward of the inner member 10 are fitted into two openings 13 provided in the outer member 9. The outer member 9 and the inner member 10 are integrally fixed.
The outer member 9 and the inner member 10 can be screwed and fixed with bolts or the like.

The outer member 9 fitted through the mounting opening 14 of the door 1 is fixed to the door 1 by fitting a U-shaped ring 15 into the outer member 9 from behind the door 1.

[0009]

As described above, in the disk tumbler lock device of the present invention, the fixing body 2 is connected to the outer member 9 and the inner member 1.
0, and is fitted and fixed to the outer member 9
A plurality of receiving holes 7 pierced through the side wall of the inner member 10 and separated by partition walls 8 are provided in an isolated manner, and the distal ends of the disk tumblers 6 are independently engaged in the receiving holes 7 in the locked state. As a result, each disk tumbler 6 can abut against the front partition 8 to resist pulling out of the rotor 3, so that unauthorized unlocking due to violent destruction can be more effectively prevented.
