Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

First, FIG. 1 is a view illustrating a form in which a tempered glass door and a glass door exclusive door lock having an illegal anti-thaw blocking function according to an embodiment of the present invention are installed, and show an inner portion of the glass door that can directly operate the door lock.

Referring to the drawings, one side of the glass door 1 made of tempered glass is provided with a door lock 10 that locks or opens the glass door 1 by moving the dead bolt 14 forward or backward. The dead bolt 14 of the door lock 10 is formed in the form of one or a plurality of rods, and the user manually manipulates the manual knob 11 installed in the door lock 10 located at the inner part of the glass door 1 to lock or It is configured to move to the open state.

The manual knob 11 may be formed in the form of a rotatable handle for the user to conveniently operate, or may be made in the form of a moving handle that can be slid left and right or up and down. In one embodiment of the present invention, illustrated and described as being in the form of a rotary knob.

On the other hand, the safety clearance 5 which remove | eliminated a part of tempered glass is formed in one side surface of the glass door 1. As shown in FIG. This safety clearance 5 is for preventing the accident of the user's finger using the glass door 1 is caught in the door clearance. In addition, a flexible rubber membrane 6 may be installed in the safety clearance 5, and prevents too much air from flowing out or flowing through the clearance of the safety clearance 5.

In the glass door formed with the safety gap 5 which is a relatively wide gap, a tool specially designed to rotate the manual knob 11 may be inserted through the gap of the safety gap 5, thereby causing illegal unlocking. .

However, since the precise and delicate operation is required when operating the manual knob 11 using such an illegal tool, it takes about 5 minutes even for the expert. Glass door door lock having an illegal unlocking function according to an embodiment of the present invention is focused on the fact that it takes a considerable time even for illegal unlocking using illegal tools.

Figure 2 is a simplified block diagram showing the configuration of a door lock exclusively for glass doors with illegal unlocking function according to an embodiment of the present invention. Referring to the drawings, the glass door-only door lock 10 having an illegal release lock function according to an embodiment of the present invention, the knob position detection unit 12, the counter 13, the dead bolt blocking unit 15 and And a control unit 19.

The knob position detection unit 12 detects whether the manual knob 11 of the door lock is turned to the current lock position or to the open position. For this sensing, the knob position sensing unit 12 may include one or more pairs of light emitting elements / light receiving elements for detecting the blocking and transmission of light by a part of various instruments constituting the manual knob 11. have. That is, the first light emitting element / light receiving element pair in which light is blocked only when the manual knob 11 is turned to the locked position, and the second light emitting element / light receiving element in which the light is blocked only when the manual knob is turned to the open position. Pairs may be provided.

According to this configuration, when the manual knob 11 is in the locked position (knob locked state), the blocking of the first light emitting element / light receiving element pair can be indicated, and the light sensing of the second light emitting element / light receiving element pair is suppressed. I can display it. While the manual knob 11 is being turned from the locked position to the open position (knob operating state), light sensing can be displayed on both the first light emitting element / light receiving element pair and the second light emitting element / light receiving element pair. Subsequently, if the manual knob 11 reaches the open position (knob open state), the first light emitting element / light receiving element pair indicates light sensing and the second light emitting element / light receiving element pair indicates blocking.

Normally, when the user operates the door lock 10, the time that the manual knob 11 is rotated by the user to move from the knob lock state to the knob open state can be estimated to be about 1 to 3 seconds.

On the other hand, one side of the manual knob 11 from the light emitting device or a specific type of blocking projection 112 that can block the light from the light emitting device to control the light blocking and incidence in the light emitting device / light receiving device pair A specific type of through hole (not shown) may be formed to allow light to pass therethrough. In the present embodiment, the blocking protrusion 112 will be described.

The blocking protrusion 112 may be installed in a form directly added to the manual knob 11 or may be installed in a predetermined mechanism connected to the manual knob 11 to operate mechanically or electrically. In addition, although it is possible to form a separate blocking projection, it is more preferable to make it possible to control the blocking and transmission of light without forming a separate blocking projection by utilizing the form of a conventional mechanism to the maximum.

Meanwhile, the knob position detecting unit 12 may be a switch pressed by the rotation of a part of the manual knob 11 or an added protrusion (for example, a shading protrusion). That is, a switch that is pressed when the manual knob 11 is in the locked position and released when starting rotation from the lock position, and another that is pressed when the manual knob 11 is in the open position and released when starting the rotation toward the locked position. It may be provided with a switch of, and may be configured to detect the state of the knob 11 as each switch is released.

The counter 13 measures time according to the input signal, and is set to count the time that the manual knob 11 is kept in the knob operation state. That is, only the time from the time when the manual knob 11 is out of the knob lock state to the time when the knob open state is reached is counted. The signal for controlling the start and stop of the count may be provided directly to the counter 13 by the knob position sensing unit 12, but the control unit 19 to be described later controls according to the sensing result of the knob position sensing unit 12. More preferably.

The dead bolt blocking unit 15 is made impossible to drive the dead bolt 14 temporarily or until an additional releasing procedure is input by a normal user according to a control signal input according to the operating state of the manual knob 11. Block it. As a result, illegal unlocking operation can be blocked.

The dead bolt blocking unit 15 may apply a separate clamp (not shown) to a gear or solenoid associated with driving the dead bolt 14 to prevent the dead bolt 14 from moving in an open state. Forcibly shuts off the drive.

The illegal unlock operation detection and blocking operation is performed by the controller 19. When the knob position detecting unit 12 detects the moment when the manual knob 11 moves from the locked position to the open position, the controller 19 drives the counter 13 to measure the time, and the measured time is a predetermined time. When the allowable time is exceeded, the dead bolt blocking unit 15 is controlled to block the driving of the dead bolt 14.

That is, the controller 19 may check whether the manual knob 11 is in the locked position or the open position by using the knob position detector 12. If the manual knob 11 is found to be out of the locked position, it is sensed that the manual knob 11 is operated by an external force to rotate toward the open position, and the counter 13 is driven. The control unit 19 monitors the time measured by the counter 13 and compares it with the allowable time previously stored. If it is determined that the measured time exceeds the allowable time, the manual knob 11 is regarded as abnormally slowly rotating and is determined to be illegally released, and the dead bolt breaking unit 15 is operated to operate the dead bolt ( 14) will be forcibly blocked. Alternatively, the rotation of the manual knob 11 may be blocked.

On the other hand, the counter 13 may count only up to a pre-stored allowable time, and when the count is completed, the counter 13 generates a predetermined alarm signal, and the manual knob 11 even until the alarm signal is input from the control unit 19. If it is not moved to the open position may operate the dead bolt blocking unit 15 as described above.

3 is a view for explaining a simple example of the operation of the manual knob and knob position sensing unit in the door lock dedicated door lock with illegal unlocking function according to an embodiment of the present invention. 3 (a) shows the state in which the manual knob 11 is in the locked position. At this time, the light shielding projection 112 of the manual knob 11 is located in the first light emitting element / light receiving element pair to block light between the light emitting element / light receiving element pair. On the other hand, light is not blocked in the second light emitting device / light receiving device pair.

3 (b) shows the state in which the manual knob 11 is in the open position. In this case, the light blocking protrusion 112 of the manual knob 11 is positioned in the second light emitting element / light receiving element pair to block light therebetween, and the light of the first light emitting element / light receiving element pair is transmitted.

With reference to Figure 4 will be described with reference to the illegal unlocking method by the door lock dedicated door lock with an illegal unlocking function according to an embodiment of the present invention made in such a configuration.

First, the door lock 10 checks where the manual knob 11 is currently turned. And if it is confirmed that the current lock state (S11), the control unit 19 executes the illegal release blocking function according to the present invention. In this state, if it is detected that the manual knob 11 rotates from the locked position (S12), the control unit 19 drives the counter 13 to measure time (S13). And it is monitored whether the measured time exceeds a pre-stored allowable time (S14).

If the measured time exceeds the allowable time, it is assumed that the manual knob 11 is slowly rotating by the illegal unlocking operation (S15), and the rotating or dead bolt 14 of the manual knob 11 is assumed. ) Is forcibly blocked (S16). At this time, at least the dead bolt 14 releases the movement until just before the forced interruption operation is performed, and returns it to the locked state.

On the other hand, if the time measured by the counter 13 is stopped within the allowable time, it can be determined that the manual knob 11 is completely rotated to the open position within the allowable time, and the manual knob 11 is normal by the legitimate user. It can be regarded as unlocked (S17), and the unlocked state of the dead bolt 14 can be maintained (S18).

The present invention having the configuration as described above, in the door lock dedicated door with a dead bolt and the manual knob, the time to rotate or move the manual knob from the locked position to the open position lasts until a predetermined reference time If so, the door lock may be regarded as being illegally unlocked, and by automatically blocking the movement of the dead bolt or keeping the door lock locked, the illegal unlocking operation using the safety gap may be blocked.
