Abstract

The moveable mechanical closure has no direct mechanical connecting element between lock (20) and operating device (25). The operating device on the outside of the door does not indicate the position of the locks (20) and blocking points (14l...14m...14n). The armour plating of the door is not perforated at critical points by connecting elements. The number of locks (20) and blocking points (14) can be multiplied to form the operating unit. Locks and blocking points can be varied in position from door to door, because they are independent of the position of the connecting elements and operating device. An electronic operating device (45) has storage means (45<III>, 45<IV>) and contains a microprocessor (45'). A keyboard (35) of the operating means for the lock (20) or locks can be arranged remotely from the door (1). <IMAGE>

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lock device such as a door.

BACKGROUND OF THE INVENTION Mechanical locking devices are repeatedly opened and closed,
Locked. Such devices are applied, for example, to all types of doors (folding doors, sliding doors, revolving doors, flip-up doors, lattice doors, etc.), windows, covers, barriers and the like. In this specification, these application targets are referred to as “doors”.

Conventional locking devices have several drawbacks that do not meet the safety requirements of a door lock. A wide variety of attempts have been made to remedy the shortcomings of conventional systems, many of which have been armored.
oring).

An example of a well known mechanical drawback is the locking linkage for actuating the bolt. With the lock bar, the bolt or bolt beam with bolts is connected to the locking point.

Therefore, a mechanical lock bar is manufactured for such a function only. At locations where large forces may be applied (eg bolts), the lock bars are oversized to maximize safety. This also applies to some extent to bolt beams.
The lock bar, part of which is inside the additional armor protection,
The dimensions are oversized to prevent breakage as much as possible. One of the mechanical weaknesses in the safety of the conventional system is that the lock mechanism is pivotally joined to the lock bar. This point is called the lock point. Even if there are a plurality of lock points or the structure of the lock mechanism is sophisticated, the safety of the lock depends on only one place, that is, the lock point, and that place breaks the entire locking device.

The lock bar, which prevents the bolt from moving freely, is released from the locking mechanism by externally piercing the lock point. When the lock bar is released, the lock loses its locking function. When the lock bar is released, the bolt engaging the door frame is free to move. Therefore, for example, the lock point and the lock point must be covered with a cover plate having a hardness that can resist drilling, and the lock point must be specially protected. An example of the cover plate is corundum which is a metal mixture.
Undum) composite plates can be used.

The position of the lock point must be kept secret even if these protective measures are taken. Knowing its location allows the door to be opened illegally by patiently destroying the pest control means. When a normally unknown lock point position is found, the lock position becomes known. The locked position is limited in part by the lock release device on the outside of the armored door. Due to the narrowing of the area where the lock point may be located and the knowledge of the lock types (the lock types are very diverse) it is possible to open the safe door without a key or code. become able to. In addition, all locks require a connection that extends outwardly through the hole in the armor and a manipulator located outside the door that indicates the position of the lock point, so the number of locks, and therefore The number of lock points will be very limited.

Another significant drawback is inherent in the locking mechanism. The combination locks used in safes can be unlocked by a code determined in the lock by the relative positioning of a given combination of coding discs. Inner unboltin
g) it is possible to activate the locking mechanism, for example an outer umb between the door and the frame.
You can open the safe.

In a properly locked safe, the combination lock is activated by the decoding of the coding disc. No matter what the angular position of the discs relative to each other, according to the combination, if all the positions of the ambolt parts on the coding discs are steadily pointed, the internal ambolt will actuate the locking mechanism for unlocking. be able to. The coding disc operated for unlocking is kept in the operated state. After unlocking the door, this condition will not be canceled automatically. Canceling the operation state is called code scrambling and must be performed very carefully. The code must be scrambled so that it can only be opened again by the correct manipulation of the coding disc, but in practice it is often forgotten.

Properly scrambling the unlocking code involves changing the state of each of the typically three to four coding discs. By chance, when scrambling, the release groove (re
It is said that the turn of the release groove is performed only 10 degrees, so that this state can be sought by a skilled search technique, and by slightly turning the combination knob, the door can be properly unlocked and the door can be opened. .

Those with the authority to open and close the door usually do not understand the mechanism of this lock. The important thing is to change the unlock code from time to time. One of the worst is that I think I've inserted a new code, but the lock doesn't release and the door doesn't open. On the other hand, it is dangerous to leave the state in which the first code set in the factory is known to a person who does not have the unlocking authority for a long period of time due to changes in employees.

Embodiment Hereinafter, one embodiment of the present invention will be described with reference to the accompanying drawings.

FIG. 1a is a front view of a conventional armor door. In the drawing, the display of the door frame is omitted. On one side of the door, a door hinge of ordinary structure, for example, a rectangle (11), is provided. Bolt beam on the other side of the door
A plurality of bolts (12) located above (15) are shown.
The bolts (12) are laterally movable so that they can move in and out of corresponding recesses in the frame.

The bolt beam (15) is adapted to move with the bolt (12). This movement is transmitted to the bolt beam (15) by the bolt drive (30). For simplicity, conventional locking mechanisms are represented by the dotted squares and circles therein. A circle is a keyhole for an operating system (25), such as a number combination knob, key.

One end of the lock bar (13) is part of the bolt beam (15).
(13 '), and the other end is rotatably joined to the lock point (14). The lock point (14) is the lock bar (1
It fixes or releases 3) and is preferably protected behind the armor (22).

The above parts correspond to known prior art.

Figure 2a is a simplified drawing of an armored door (1) according to the present invention. The door has a bolt beam with bolts (12)
(15) Lock actuating part of mechanism connected to bolt beam (15) through two hinges (11) and lock bar (13)
(20) is provided.

According to the invention, the lock point coordinates (14 ₁ , ... 14 _m , 14 _n ) are arranged over most of the door part and are distributed in a regular or irregular manner. With free choice, multiple lock point coordinates are used to activate the lock. In the drawing,
One of the selected lock point coordinates is represented by (14 _m ).

By making this work, no copper wire connections from outside the door are required to activate the lock. That is, the lock operating part (20) is electrically remotely controlled. If desired, an electrical cable from the exterior to the interior of the door can be passed through the door hinge.

The lock actuating part (20) shown in FIG. 2a can be arranged at each coordinate (14 ₁ to _n ), and in FIG.
(20) is shown. An electric wire (40) is connected between the lock operating part (20) and the operating part (25). The operation unit (25) itself can be provided in a single place or a plurality of places. Therefore the coordinates (1
4 _m ) and any of the other coordinates (14 ₁ - _n ),
A lock actuating part (20) and a lock bar (13) acting on a common bolt beam can be provided. That is, either the one operating part or the two operating parts causes the two lock actuating parts to be unlocked, and the bolt beam is released to open the door. In this way, the set number of the operating section (25) can be appropriately selected, so that the lock device can be adapted to a wide range of applications. These will be described with reference to FIG.

FIG. 3 is a schematic representation of the elements used for opening the "inside" lock actuation portion of an armored door by electrical remote control. The code is input on a device that is not mechanically connected to the lock actuator and is not added mechanically by turning the combination knob, so that the lock mechanism itself mechanically remembers the code. No need. If an electronic memory can be used to hold the unlock code, it is advantageous to use a microprocessor. Therefore, the right side of FIG. 3 shows a typical conventional microprocessor. The program may be stored, or the operation program may be hardware of a simple logic circuit. A data memory for receiving open and close codes and other data for increased security can also be used.

The processor is connected by input / output circuits to peripherals including one or more mechanical locking devices. In this example, the armored door of Figure 2a is used. An electric wire extends from the door hinge (11) into the inside of the lock actuating portion, where a motor drive mechanism for the lock actuating portion is provided. When the lock operating part (20) is unlocked, the external bolt between the bolt (12) and the door frame can be moved to the unlocked position by the bolt drive (30).
As a result, the door can be opened.

An input keyboard (35) can be used to enter the unlock code. Status information, memory contents, etc.
It can be displayed on the display 34 as usual. Similar to FIG. 1a, the operating system (25) is shown. In Figure 1a, the operating system is a keyhole that cooperates with a number combination knob or key. In the embodiment of FIG. 3, the operating system is a keyboard (35) which is preferably arranged outside the door. The electric circuit parts (45a to 45e) necessary for the operation of the lock operation part are provided on the side protected through the door. In FIG. 3, the entire operation unit (45) includes a processor having a memory, a peripheral device interface and a keyboard (35). One or more keyboards can be provided on the door, near the door or at a remote location.

When the cashier opens the safe door, he enters a code he knows from the keyboard near the door. Only when the person in charge enters a code that only the person in charge knows from the keyboard in his room, the lock actuator is opened. Only with these two cords can the lock actuator be released and the cashier can use the bolt drive (30).
Allows you to open the door completely.

As a result, even if he threatens a cashier and finds out a code he knows, it's completely impossible to break into the safe. The cashier contacts the person who is not there,
The responsible person may teach a code that only the responsible person knows to keep the cashier safe. However, the responsible person can activate the closing device and the alarm device at the same time to notify the police.

FIG. 4 shows an embodiment of the block diagram shown in FIG. A microprocessor with a memory for user programs, a memory for key data and an I / O circuit is arranged in the door area (1) or in the safe. I / O
From the circuit, the dotted line shows the keyboard (35) via the hinge (11).
Extends to. The keyboard (35) is located outside the door area and is connected to the electronic system in the door area via the line (40). A dotted line (50) extends from the I / O circuit to a lock actuation system (55) that converts an electrical quantity into a mechanical driving force. The conversion of the electric quantity into the mechanical quantity by the lock actuation system (55) is performed by the electric wire (50) extending to the lock actuation system (55) and the mechanical connecting device (5) extending to the lock actuation part (20).
Indicated by 0 '). The lock operating part is released via the mechanical connection device (50 ') to the lock operating part (20), the lock bar (13) is operated, and the bolt beam (15) causes the lock bar to move from the lock point (14). To be released. Bolt beam
It has a bolt (12) that engages with the door frame. The operation content for operating the door lock is stored in the user program memory. The key data memory receives all user-specific data needed for electronic control of the safe. These data are entered and analyzed via the keyboard (35) located outside the door area.

In the operation procedure, electric operation for lock operation is performed. The operating procedure is designed so that only a dynamic process satisfying a predetermined specification has some effect. Static conditions have no effect on the actuation of the lock. The operation of the lock can be performed by, for example, an AC motor controlled by such an operation amount. The control system is a motor torque band.
band).

Long lasting unidirectional voltage levels cannot be used to initiate a lock open / close operation, such as in a DC motor. In frequency-dependent operation, the door can be opened only by a dynamic amount of electricity corresponding to a given parameter. Any other condition holds a positive lock on the mechanical locking device.

The most important steps in the operating procedure are listed below.

1. Operating frequency
Preparation of cy) 2. Receive status information about lock position. Programmatic decision as to whether opening should take place 4. For example, status information within the time window about the opening or closing of the lock. If this condition is not met, a fault will be issued.

5. The position of the lock and return bolts of the electronic system to the initial state and the position of the door are determined for monitoring the armored door. This information is determined, for example, by the location of the microprocessor. For the detection of the position of the door plate, it is preferable to use the device disclosed in Swiss Patent No. 629565. The logic table below shows the basic states of the locking device.

In the above table, R = position of bolt (for example, position of door bolt (12)) α = position of door (for example, door angle) 0 = bolt open 0 = door open (for example, large α) (a) In state "a", the door is closed and the bolt is advanced. This state electronically corresponds to a neutral state or a fixed function. When this state is reached, the lock operation has been completed.

(B) The door is already closed (that is, the door has been pivoted to the closed position and the door position detection device indicates that the door is closed), but the door is ready to be reopened. The armored door is properly closed but not locked. This condition is often overlooked and often leaves the safe in this condition. According to the device of the present invention, this abnormal state is displayed in the time window by the microprocessor.

(C) The bolt is advanced and the door is open, which is preferably avoided. This can be easily avoided by adapting the user program. The abnormal state is displayed in the time window in the same manner as the state “b”. However, it is advantageous to provide a circuit that ensures that such a condition never occurs.

(D) Like the state “a”, the state “d” is also the target position to be reached. The bolts and doors can be opened and you can enter the safe. If this state occurs outside the predetermined working time of the cashier, an alarm state is given by the microprocessor. This prevents unauthorized persons from opening the system outside of the predetermined time (which can be changed). State "d" (bolt open, door pivoted outward) is the state where the entire system can be programmed. If there is an operation error associated with the release of the lock device, it is possible to enter the safe even if the device does not malfunction. However, the locking device can be reprogrammed in the event of an erroneous operation to bring it into an emergency without impeding its entry into the safe.

As mentioned above, making the closure device electronically based provides a number of advantages.

After storage in the safe, closing the door and then locking the door bolt without locking the cord can be scrambled automatically. Therefore, neglecting to scramble the code is impossible.

Setting up new code and making regular changes is extremely easy. The incorrect code is removed by making a new input. If an incorrect code is entered into a mechanical locking device, the incorrect code entry must be defeated by an expert in order for the correct code to be finally entered.

The lock operating part automatically operates the bolt. Automatic door closure can also be included during this operation.

For safety, the complexity of the lock operation can be increased quickly without difficulty. For example, the third code and the fourth code can be cooperated. This is absolutely impossible with mechanically coded locking devices.

Based on the contained intelligence, numerous changes are made without changing the locking device.

In the system according to the invention, disabling the lock point in the armored door is tedious and difficult. The position of the lock actuator is unknown and cannot be found on the outer surface. The number of lock operating parts and lock points is
The number can be increased without increasing the number of holes penetrating the armor and without increasing the number of connecting elements with the outside.

The lock point is always with the lock actuator between the protective armor layers. Therefore, the lock actuator and the lock point are completely hidden and there is nothing on the outside to suggest its position.

By providing a plurality of lock operating parts, the possibility of unauthorized unlocking is significantly reduced. Moreover, their positions cannot be determined externally and are different in each case.

Effects of the Invention According to the present invention, it is possible to provide a locking device that exhibits the following effects. That is, the lock device is provided with a plurality of lock operating portions that lock and unlock the bolt beam with a code for unlocking or locking entered by the operator, and the lock operating portions are independent of each other. Since the lock control unit that locks or unlocks the beam is provided, unlocking is possible only when correct unlock codes are given to the plurality of lock actuating units. Therefore, as compared with a lock device that can be unlocked by giving a single unlocking code, there is less risk of unauthorized unlocking. Further, the locking device has a bolt beam that extends in an elongated shape, and a plurality of bolts extend substantially vertically from the bolt beam at intervals from each other. It can be prevented more strongly than a lock device. Further, since a plurality of lock actuating portions for fixing and releasing the fixing of the bolt beam are attached to the bolt beam at different positions in the longitudinal direction, the length of each lock bar for connecting to the bolt beam is also increased. Differently, the elongated bolt beam can be used to arrange the lock operation portion in an extremely wide area inside the door. Since the lock actuating parts independently fix or unfix the bolt beam, it is necessary to destroy all the lock actuating parts which are different for each locking device, in order to perform the illegal unlocking. Therefore, it is extremely difficult to perform an unlocking operation on the lock operating portion from the outside of the door by opening a hole or the like. In the device of the present invention, in addition to the prevention of unauthorized unlocking based on the plurality of bolts described above, high safety is ensured against such a hard and unauthorized unlocking operation that extends to the inside of the door.
