DETAILED DESCRIPTION OF THE INVENTION
Next, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 (A) is a perspective view showing a part on the outer surface side of a building door in which the locking / unlocking device of the present invention is implemented, and FIG. 1 (B) is a perspective view showing a part on the inner surface side of the door.
[0025]
As shown in FIG. 1A, an outer lock portion 11 of the locking / unlocking device, an outer door handle 12, and an auxiliary cylinder lock portion 13 are provided on the outer surface of the door 10, and embedded in the door 10. Thus, the controller 14 of the locking / unlocking device is provided.
[0026]
As can be seen from the enlarged front view shown in FIG. 2, the outer lock portion 11 has a key insertion portion 15 for a cylinder lock, a touch switch 16, a display portion 17 for locking / unlocking, and a transmission / reception portion 18 for code signals. I have it.
The transmitting / receiving unit 18 is formed of a synthetic resin material or the like, and is provided when the case 22 is made of metal, and is not necessary when the case 22 is formed of a synthetic resin material or the like.
[0027]
Further, as can be seen from the internal configuration diagram enlarged in FIG. 3, the outer lock portion 11 includes a transmission antenna 19, a reception antenna 20, a capacitor 21 arranged close to the transmission antenna 19, and other switches of the touch switch 16. The part and the like are arranged on a substrate 23 provided in the case 22.
[0028]
The transmission antenna 19 is formed by winding a conductive wire around a magnetic material, and the transmission antenna 19 and a capacitor 21 form a series resonance circuit.
That is, the challenge code signal and the call code signal are sequentially transmitted from the transmission antenna 19 sequentially using the resonance current of the series resonance circuit.
[0029]
The challenge code signal and the call code signal are transmitted as an LF (125 kHz) magnetic field signal using, for example, an electromagnetic wave having a high distance attenuation in consideration of radio wave interference with peripheral wireless devices.
[0030]
The receiving antenna 20 is a known antenna made of a rod-shaped conductor, and receives a high-frequency radio wave transmitted from the portable device 50 (see FIG. 1), for example, a response code signal of RF (315 MHz) as a radio wave signal.
[0031]
The display unit 17 displays green light in the locked state and red light in the unlocked state, so that the person who locks and unlocks can visually confirm the locking and unlocking.
[0032]
The transmission / reception signal of the outer lock portion 11 is processed by the controller 14.
That is, the controller 14 has a control circuit having a memory such as RAM and ROM, a timer, etc. in addition to the CPU, and outputs a challenge code signal and a call code signal from the transmission antenna 19 under the control of the controller 14. .
The challenge code signal is an arbitrary random number code signal.
The call code signal is obtained from the call code set in advance in the controller 14 in accordance with the order of registration in the controller 14 of the portable device 50, and is stored and held in the memory in correspondence with the ID code of the portable device 50.
[0033]
The controller 14 inputs the response code signal received by the receiving antenna 20, compares the response code with the internal response code generated from the transmitted challenge code and stored in the memory, and the codes match. When it does, it will be in unlocking preparation mode.
The response code signal is a code signal calculated in the same manner as the locking / unlocking device side from the ID code of the portable device 50 and the received challenge code, and is output from the portable device 50.
[0034]
Further, when the controller 14 operates the touch switch 16 in the unlocking preparation mode, the controller 14 responds to the input of the switch signal and controls the unlocking mechanism 24 (see FIG. 1) to unlock the electric drive unit (built in the thumb turn device). Then, the dead bolt 25 (see FIG. 1) in the locked state is withdrawn and unlocked.
[0035]
When the door is opened and closed after unlocking, or when the door is not opened and closed within a predetermined time, the controller 14 controls the electric drive unit of the unlocking mechanism 24 to lock the door.
[0036]
The outer door handle 12 shown in FIG. 1 has a structure that interlocks with a latch mechanism. For example, in the case of a push-open door 10, when the door handle 12 is pushed, the latch bolt 26 moves backward to open the door. Can do.
Note that when the pushing operation of the door handle 12 is released, the latch mechanism automatically returns.
[0037]
The auxiliary cylinder lock 13 shown in FIG. 1 locks and unlocks the locking / unlocking mechanism 27 by a key operation, and this locking / unlocking mechanism 27 is controlled by an electric drive unit provided in the auxiliary thumb turn.
That is, the electric drive unit is controlled by the controller 14 described above to be locked and unlocked in the same manner as the outer lock unit 11.
[0038]
On the other hand, as shown in FIG. 1B, an inner lock portion 31, an inner door handle 32, and an auxiliary thumb turn 33 are provided on the inner surface of the door 10.
The inner lock portion 31 has a structure in which a thumb turn device and a transceiver are unitized. As shown in an enlarged front view in FIG. 4, a thumb turn knob 34, a touch switch 35, and a lock / unlock display portion 36 are provided on the front side. Are provided.
[0039]
Further, as can be seen from the internal configuration diagram enlarged in FIG. 5, the inner lock portion 31 includes a transmission antenna 37, a reception antenna 38, a capacitor 39 that forms a resonance circuit with the transmission antenna 37, and a switch portion of the touch switch 35. Are disposed on a substrate provided in the case 40.
[0040]
Note that the touch switch 35, the transmission antenna 37, and the reception antenna 38 have the same configuration as that provided in the outer lock portion 11, and operate similarly under the control of the controller 14.
[0041]
Further, the inner lock portion 31 is provided with an electric drive portion 41 that drives the locking / unlocking mechanism 24 by a motor.
The electric drive unit 41 is provided with a clutch mechanism that disconnects the electric drive system when the cylinder lock of the outer lock 11 is operated by key operation or when the thumb turn knob 34 is operated.
[0042]
Inside shown in Fig. 1 (B) door The handle 32 is interlocked with a latch mechanism in the same manner as the outer door handle 12, and this handle Inside When the door handle 32 is pulled, the latch bolt 26 can be retracted to open the door.
In addition, Inside When the pulling operation of the door handle 32 is released, the latch mechanism automatically returns.
[0043]
The auxiliary thumb turn 33 shown in FIG. 1 includes an electric drive unit and a clutch mechanism similar to the electric drive unit 41 provided in the inner lock unit 31, and locks and unlocks by the operation of the electric drive unit controlled by the controller 14. It is.
[0044]
Next, the operation of the locking / unlocking device described above will be described with reference to the flowcharts of the controller 14 shown in FIGS.
In addition, since the operation | movement at the time of transmission / reception of the outer side lock part 11 and the inner side lock part 31 becomes the same, operation | movement at the time of transmission / reception of the outer side lock part 11 is demonstrated.
[0045]
First, when the controller 14 is started, a challenge code signal is transmitted from the transmission antenna 19 of the outer lock 11.
At this time, the controller 14 creates an internal response code calculated from the code of the transmitted challenge code signal and the ID code of the portable device corresponding to the subsequently transmitted call code, and stores it in the memory.
This call code signal is a to an + 1 code signal set corresponding to the registration of a plurality of portable devices, and is stored in the memory in association with the ID code of each portable device.
The challenge code signal is transmitted alternately with the call code signal divided into types a to a + n. (FIG. 6, ST100 to ST103)
[0046]
When the person holding the portable device 50 approaches the door 10 and the portable device 50 outputs a response code signal, the reception antenna 20 of the outer lock portion 11 receives the response code signal. (Fig. 6 ST104)
The response code signal received by the receiving antenna 20 is processed as an external response code by the controller 14 and compared with the internal response code. (Fig. 6 ST105)
[0047]
If the portable device 50 has an ID code corresponding to one of the calling code signals a to a + n, the external response code matches the internal response code, so the controller 14 determines that these codes match. Move to lock / unlock preparation mode. (Fig. 6 ST106)
[0048]
In this preparation mode, the locked / unlocked state is determined, and if locked, the display unit 17 is lit in green and waiting for unlocking operation, and if unlocked, the display unit 17 is lit in red and waiting for locking operation. . (FIG. 7 ST108 to ST111)
[0049]
After confirming that the display unit 17 is lit, the person who has the portable device 50 operates the touch switch 16 in this standby state.
When the touch switch 16 is not operated, the process returns to the first step ST100 (ST112 and ST113 in FIG. 7).
[0050]
When the touch switch 16 is operated in the unlocking standby state in step ST109, the controller 14 controls the electric drive unit 41 according to the switch signal to unlock the touch switch 16.
Then, the automatic locking timer starts counting according to this unlocking. (FIG. 7 ST114 to ST116)
[0051]
When the door 10 is opened after unlocking, the door 10 is opened without proceeding to the next step unless the door 10 is closed. (FIG. 8 ST117, ST118)
When the door is closed, the automatic locking timer starts counting, and when this timer expires, the controller 14 controls the electric drive unit 41 to lock. (FIG. 8 ST119 to ST121)
[0052]
Regardless of the unlocking of step ST114, when the door 10 is not opened, the automatic locking timer (ST116 in FIG. 7) is timed up to lock. (FIG. 8 ST117, ST120, ST121)
When the door 10 cannot be opened, the door 10 is locked by operating the touch switch 16 during the counting of the automatic locking timer (FIG. 7 ST116). (FIG. 8 ST117, ST120, ST121, ST122)
[0053]
After automatic unlocking after unlocking as described above, the internal response code is deleted, and the process returns to the first step ST100. (FIG. 8 ST123, ST124)
[0054]
Further, in the locking standby state in step ST111, since it is unlocked, it is locked by operating the touch switch 16. (Fig. 7 ST113, ST125)
After locking in this way, the internal response code is deleted, and the process returns to the first step ST100. (FIG. 7 ST126, ST127)
[0055]
On the other hand, when the response code signal is not received from the portable device 50, or when the response code signal is received but does not coincide with the internal response code as the external response code, the calling code is switched. (FIG. 6 ST104, FIG. 9 ST128, ST129)
[0056]
When the call code signal is switched and transmitted and the response code signal is received, the process proceeds to the step after step ST104, and if the response code matches the internal response code, the process proceeds to step after step ST106.
[0057]
Even if the call code signals a to a + n are switched and transmitted, when the response code signal is not received or when the code of the received response code signal does not match the internal response code, the unlocking standby state is canceled. (FIG. 9 ST130, ST131)
Then, the internal response code is deleted, and the process returns to the first step ST100. (FIG. 9 ST132 to ST134)
[0058]
Although the operation of the outer lock portion 11 and the controller 14 has been described above, the operation of the inner lock portion 31 and the controller 14 is the same, and thus the description thereof is omitted.
[0059]
FIG. 10 is a flowchart showing the operation of the portable device 50.
The portable device 50 includes a memory such as a RAM and a ROM in addition to the CPU. The portable device 50 is activated from a sleep state by receiving a challenge code signal transmitted from the outer lock portion 11 of the door 10. A response code calculated from the ID code unique to the portable device is created and stored in the memory. (FIG. 10 ST2001 to ST2003)
[0060]
Then, by receiving the call code signal, a response code signal is transmitted when the call code of the portable device 50 is matched.
Further, after transmitting the response code signal, the stored response code is deleted and the process returns to the first step. (FIG. 10 ST2004 to ST2007)
[0061]
If the call code signal is not received for a predetermined time even if the challenge code signal is received, or if the call code does not match, the response code is deleted and the process returns. (FIG. 10 ST2004, ST2005, ST2007, ST2008)
[0062]
FIG. 11 is an exploded perspective view showing a state before the outer lock portion 11 and the inner lock portion 31 are attached to the door 10.

[0065]
On the other hand, in this embodiment, a circular protective member 46 having a hole through which the cylinder interlocking shaft and the mounting screw 45 are passed is provided, and the protective member 46 is disposed between the cylinder portion and the locking / unlocking mechanism 24.
[0066]
That is, as can be seen from the assembly diagram of FIG. 12, the dead bolt rotating shaft portion of the locking / unlocking mechanism 24 is closed by the protective member 46 to prevent unlocking due to fraud.
[0067]
That is, when the case 22 of the outer lock portion 11 is formed of a synthetic resin material, the case 22 may be destroyed. In this case, as shown in FIG. Dead by the tool 47 inserted from the mounting hole 10b bolt The rotating shaft 48 may be rotated and illegally unlocked.
The protective member 46 described above solves such a problem.
[0068]
As described above, the embodiment of the present invention has been described. However, the challenge code signal and the call code signal are not configured to be transmitted at all times, and those who have the portable device 50 approach the door 10 and operate the touch switch 16 to perform these operations.
