It is intended to obviate the problems experienced in the context of the prior art briefly described above by the means of providing a blockage mechanism in the framework of the present invention.

[0026]

The present invention generally relates to a blocking mechanism comprising two sheets (11, 16) having fins (13, 20) in a protruding form on their side surfaces, wherein when said fins ( 13, 20) When they reach the same horizontal axis, they are matched to each other and provide locking.

[0027]

There are many commercially available locking mechanisms in the current state of the art. Whether or not the locking mechanism shown in the drawings of the present invention is a lever lock mechanism, it will be apparent to those of ordinary skill in the art that a blocking mechanism can also be used in embodiments in which the locking mechanism is as described by the locking mechanism. Slide the lock or other mechanism.

[0028]

The lever lock mechanism defined in the drawings shown in the present invention is based on the principle that the plate is positioned in such a manner as to permit movement of the bolt according to a password or encryption on the key (23); the bolt (18) is a key (23) Moving with the aid of the applied mechanical effect; thus performing locking and unlocking. In the event that a lever lock is used instead of a lever lock, the horn lock placed in the housing of the horn lock is rotated by a suitable key and the applied motion is transmitted to the outside by means of a suitable appliance.

[0029]

In Fig. 3, the blocking mechanism attached to the lever lock mechanism is located between the inner part of the lock and the lock side body cover. The drive plate (16) located on the set of latches including the latch (18) and the tail end of the latch (19) is moved in a linear direction (+X, -X) in synchronization with the set of latches again. ) in the way of positioning. The drive plate (16) moves in synchronism with the bolt (18) and, when possible intervention, mates with the lock plate (11) to lock the system. As can be seen in Figure 2d, there is at least one pin (17) on the drive plate (16). The driving plate pin (17) guides into a passage (24) formed on the lever lock plates.

[0030]

The lock plate (11) shown in various manners in Figures 1a to 1d is a pin located between the tail end of the bolt and the side body cover inside the lock. When the lock plate (11) and the fin (20) on the drive plate (16) reach the same horizontal plane, the lock plate (11) includes fins and fins of the drive plate (20) ) Combination.

[0031]

In Fig. 4, a lock plate (11) and a drive plate (16) constituting a blocking mechanism are shown in accordance with the present invention when the door latch (18) is moved. In the position where the door latch (18) is moved, the lock plate (11) partially closes a part in which the key (23) is inserted, and hides the mechanism underneath, making it difficult This mechanism is turned on by means of a skeleton key or the like.

[0032]

As can be seen in Figures 3 and 4, any kind of problem is caused when the bolt is normally operated by means of a gap between the lock plate (11) and the drive plate (16). In the case where the door latch (18) linearly moves in the +X direction by means of a key (23), the fins (13, 20) cause the fins of the lock plate due to the height difference (13) The gap between the fins (20) of the drive plate cannot be assembled without providing a barrier.

[0033]

The tail end (19) of the bolt (18) extends toward the interior of the lock body to be coupled to the locking mechanism by means of projections, pins, or other similar members located thereon. In the locking mechanism shown in Fig. 3, the lock plate slot (12) on the lock plate (11) and the at least one pin (21) in the lock are guided in a manner to move into the lock plate slot. (12). The lock plate is moved in the +Y and -Y directions by guiding the pin (21).

[0034]

Similarly, the driving plate pins (17) provided on the driving board (16) shown in Figs. 2a to 2d are connected in such a manner as to be movable into the passage (24). Furthermore, in order to reduce damage that may be caused by possible friction and to provide a more stable connection of the plate to the surrounding locking mechanism member, at least one drive plate hole (22) is provided on the drive plate (16), To raise the drive plate (16). Likewise, the lock plate (11) also includes at least one hole (14) that allows it to be riveted.

[0035]

In the lever lock mechanism shown in the figures, the plates overlap horizontally with a password or encryption associated with the key set. The door bolt may be retracted if the plate group is raised to an expected height by an unauthorised person.

[0036]

In the case where the lock plate (11) is raised above the level at which the key (23) needs to be raised, the fins of the drive plate connected to the set of the door are made by means of a hinge (20) Combined with the fins (13) of the lock plate.

[0037]

Fins that are interspersed into each other as a result of this contact provide for the door end (19) to move in synchronism with the loaded door latch, and thus the door latch (18) prevents itself from being retracted. Therefore, the lever lock member is prevented from being opened by external intervention.
