Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electronic locking device, and particularly to an electronic locking device that can be made smaller and consume less power.

Conventionally, locking devices called electric locks are set by connecting terminals on a terminal board with jumper wires to register the code number □, or by inserting diode pins into a board with a diode matrix configuration. Furthermore, since the control circuit was composed of relays and the like, the device was large in size and consumed a lot of power, making it difficult to run on batteries and having a narrow range of applications. Furthermore, conventional electronic memory systems require a dedicated power source to hold the memory, and have the disadvantage that the recited numbers cannot be read silently.

SUMMARY OF THE INVENTION An object of the present invention is to solve the problems of the prior art described above, and to reduce the size and power consumption of an electronic locking device.

Hereinafter, the present invention will be explained in detail according to embodiments shown in the drawings.

The figure is a schematic configuration diagram showing an embodiment of an electronic locking device according to the present invention.

This embodiment is an example in which the present invention is applied to a bar key lock used for a hinged door.

In this embodiment, reference numeral 41 is a code setting device (registration means) for setting and registering an arbitrary selected password number.

This code setting device 1 uses a rotary set of N digital code switches from which a digital code signal can be obtained, and a recitation number is set and registered by turning the rotary part 1a to match an arbitrary value.

The keyboard 2 has key switches 2a and θ~ indicated by *.
It consists of a numeric keypad switch 2b that represents numbers up to 9, and serves as an input means for unlocking.

Further, the code setting device 1 and the keyboard 2 are used for calculation and
It is connected to a control circuit (hereinafter abbreviated as CPU) 3. The CPU 3 is composed of one or more integrated circuits, and compares the numerical value of the recitation number registered in the code setting device 1 with the numerical value of the code or number input from the keyboard 2.

If both numbers match, it is considered unlocked,
A current is applied to the solenoid 5 connected to the CPU 3, and the sounding element 4 generates a signal indicating that the lock can be unlocked.

The solenoid 5 consists of a movable piece 5a, a coil 5b, and a spring 5C. When a current flows through the coil 5b, the movable piece 5a moves in the direction of arrow A, and the movable piece 5a engages the locking groove 6a of the lock 6 of the key lock. disengages from the engagement state.

One end of the bolt 6 can be inserted into the lock receiver 9 when the lock is locked, and the lower surface of the opposite end engages with the hub 7 in the locking groove 6b, and the hub 7 can be locked by turning the lever 8 in the direction of arrow B. 6
Slide in the direction of arrow C to unlock.

Next, the operation of this embodiment will be explained.

In the stick key lock in this embodiment, the lock holder 9 is inserted by sliding the bolt 6.
It is locked by inserting it into the lock and hooking it. In this locked state, the movable piece 5a of the solenoid 5 is moved by the spring 5C.
is pressed forward to prevent the sliding movement of the bolt 6, thereby maintaining the locked state. To unlock, the solenoid 5 is energized by passing current through the coil 5b of the solenoid 5. As a result, the movable piece 5a moves toward the arrow A
direction, and rotate the externally attached lever 8 in the direction of arrow B.
The lock 7 is unlocked by moving the bolt 6 in the direction of arrow C.

A key is required to unlock the lock, and a key word is used as the medium for the key. To set and register a recitation number, the rotary portion 1a of the code setting device 10 is set to an arbitrary number. To unlock this lock, press the key switch 2a marked with an * on the keyboard 2 to start up the CPU 3, input the numerical value of the registered code number from the keyboard 2, and then press the key switch 2a marked with an * again. As a result, the CPU 3 compares the registered numerical value of the code setting device l with the numerical value input from the keyboard 2, and if they match, it is determined that the lock is unlocked, and current is applied to the coil 5b of the solenoid 5 for a certain period of time, and the sounding element 4 is activated. The door is unlocked by generating a signal indicating that it can be unlocked, and by rotating the lever 8 during that time. If a numerical value different from the recited number is entered by mistake on the keyboard 2, it will be determined that the verification does not match, and current will not flow through the solenoid 5, and the sound generator 4 will make a sound different from the matching state, making it impossible to unlock the door. Let me know. Thereafter, the CPU 3 automatically enters a stopped state and does not consume power except when in use. moreover,
When you press keyboard 2 using sounding body 4, CP
, it is also possible to output a confirmation sound for the input to U3.

According to this embodiment, by using a plurality of digital code switches to register the setting of the recitation number, the number of combinations can be made infinite, and the recitation number can be easily changed by reading silently.

This makes it extremely difficult for someone else to unlock the door by groping, and there is no need to carry a key. Furthermore, in the electronic locking circuit of this embodiment, the arithmetic and control circuits are integrated into one block, making it possible to downsize the locking device and provide it with a wide range of functions, as well as to save power. Since it is equipped with a battery, it is possible to use a battery as a power source, and by removing and attaching the battery, it has the effect of providing double locking.

In addition, in the above embodiment, the case where the present invention was applied to a stick key lock with an opening Pm was explained as an example, but the present invention is not limited to this, and it goes without saying that it can be applied to any other locking device by changing the mechanism part. be.

Further, a lamp or the like may be used in place of the sounding body 4, so that the match or mismatch between the set and registered recitation number and the input numerical value and confirmation of key switch operation may be announced by light.

As explained above, according to the present invention, it is possible to reduce the size and power consumption of an electronic locking device.
