TECHNICAL FIELD The present invention relates to a bicycle locking device.

[0002]

2. Description of the Related Art Conventionally, as a bicycle locking device used to prevent theft of a bicycle, a cylinder lock is mounted on a bicycle in advance, the rotation of the wheel is regulated by the locking device, and the bicycle is moved and driven. What makes it difficult,
Pass the thing that combines the cylinder lock with the wire etc. that cannot be easily cut through the spokes of the wheel, attach the push button lock that inputs the security code to the bicycle mechanically, the one that makes it difficult to move and drive the bicycle, It is known that the locking device restricts the rotation of the wheels to make it difficult to move and drive the bicycle. Also, very recently, a bicycle has been proposed in which a lock which can be remotely controlled by optical communication such as infrared rays is attached to a bicycle in advance, and rotation of the wheels is regulated by the locking device, thereby making it difficult to move and drive the bicycle.

Further, recently proposed bicycle locking devices which can be unlocked by remote control are provided with a battery as a driving power supply so as to accept only an unlocking command from the owner of the bicycle, and receive a received signal with a predetermined identification code. The locked state can be released when they match with each other (ID code) (see Japanese Patent Application Laid-Open No. 8-260784). Therefore, the anti-theft property is higher than that of a mechanical locking device.

However, with the recent increase in bicycle theft,
There is a tendency to attach a locking device to each of the wheels (usually the front wheel and the rear wheel) to further improve the anti-theft property. In the case of this double lock method, the same thing is attached to two places, which increases the cost, and at the transmission distance boundary limit, one of them exceeds the transmission distance limit, so that there is a problem that the unlocking operation does not occur. . In addition, separate transmitters are required, resulting in a problem that portability or operability is poor, or that the configuration of the transmitter is complicated.

[0005]

SUMMARY OF THE INVENTION An object of the present invention is to provide a low-cost bicycle with excellent anti-theft and operability, which can reliably unlock a plurality of locks even near the transmission distance limit in order to meet the above demands. The purpose is to provide a locking device.

[0006]

SUMMARY OF THE INVENTION The present invention relates to a bicycle locking device comprising: a transmitter for transmitting an unlocking code having an ID code; and a plurality of locking devices provided on the same bicycle. A locking mechanism for disabling the running of wheels without using the same locking device, receiving means for receiving an unlock code having an ID code transmitted from the transmitter, and receiving means The correct ID that the received ID code matches with the stored ID code
Unlock means for unlocking the first locking mechanism based on the unlock code transmitted from the transmitter when the code is a code, and transmitting an unlock command when receiving the unlock code having the correct ID code Transmitting means having
A second locking mechanism for disabling running of the wheels, a receiving means for receiving an unlocking command transmitted from a transmitting means of the first locking device, and a lock received by the receiving means. At least one second locking device having unlocking means for unlocking the second locking mechanism based on a locking command.

According to this configuration, only the first locking device needs to be provided with means for comparing the ID code transmitted from the transmitter with the stored ID code, and the transmitter and the second locking device are provided. The cost can be reduced through simplification. Also, when three or more locking devices are provided, the first locking device may be one and the second locking device may be two or more. The first and second locking devices may be locking devices that lock the handle, in addition to locking devices that restrict the rotation of the wheels. The locking device for restraining the rotation of the wheel may be attached to the same wheel, but it is practical to attach it to the front wheel and the rear wheel.

The transmitting means of the first locking device is, for example, a radio wave transmitting circuit for outputting an unlock command using radio waves,
Alternatively, it may be an infrared transmission circuit that outputs an unlock command using infrared light.

The CPU 57 outputs a drive signal to the motor drive circuit 59 based on the unlock command, activates the actuator 18, retracts the lock body 17, and unlocks the front wheels.

The general operation of the bicycle locking device according to this embodiment is as described above. Next, the specific operation of the transmitter 30 and the receiving unit 2 of the circle lock 1 will be described with reference to the flowcharts of FIGS. It will be described in detail based on. [Unlocking Function of Transmitter 30] The flowchart shown in FIG. When the unlock switch 32 of the transmitter 30 is pressed,
An interrupt from the unlock switch 32 is input to the CPU 34 (S1).

The power supply of the CPU 36 is turned off, and the CPU 34 is set to the stop mode and stopped (S19).

[Unlocking Function of Transmission / Reception Unit 2] The flowcharts shown in FIGS. 9 and 10 are flowcharts showing the unlocking operation in the transmission / reception unit 2. When the circle lock 1 is locked, the unlock detection switch 6 of the circle lock 1
Is turned on (S21), and when the unlocked state is detected by turning on the unlock detection switch 6, the CPU 56 releases the stop mode (sleep state) and starts up (S22).
The LED built in the transmission / reception unit 2 is blinked at an intermittent period of t1 for t2 seconds (S23). In order to enhance the reliability of detection, the ID code for collation stored in the EP-ROM is read twice consecutively (S24, S2
5) If the first and second ID codes match (S26), the process waits for ID code reception. When the unlock code having the ID code is transmitted from the transmitter 30, the ID code is received (S27), collated with the ID code for collation, and if both ID codes match (S28), An unlock code is received (S29). next,
The LED is blinked at an intermittent cycle of t1 seconds for t3 seconds different from the lock time (S30), the actuator (motor) 4 is operated (S31), and after the operation of t4 seconds, the operation of the motor is stopped and the ratchet 3 is pulled up. (S32). After the above operation is completed, the CPU 56 is set to the stop mode again (S33).

[Transmission Function of Transmission / Reception Unit 2] FIG.

As is apparent from the above description, in the present embodiment, only the first lock device, the circle lock 1, receives the unlock code having the ID code from the transmitter 30 and further unlocks after unlocking. Since the lock command is output by radio waves to the box-shaped lock 15 as the second locking device, a situation where one of the locks cannot be unlocked near the transmission distance limit does not occur. A plurality of locking devices can be unlocked only by the transmitter, so that the operability and portability at the time of unlocking can be maintained as before, and the cost can be minimized. The transmitting / receiving unit 2 of the circle lock 1 and the box-shaped lock 1
Since radio waves were used as a communication medium between the receiving units of No. 5,
Unlocking is not hindered by an obstacle as in the case of the optical communication type, so that unlocking can be reliably performed and operability is improved. Since the transmitting / receiving unit 2 has a built-in LED that blinks when unlocked, the position of the bicycle can be recognized even in the dark, and the operability is improved.

FIGS. 12 and 13 are views showing a second embodiment of the bicycle locking device according to the present invention. Unlike the first embodiment in which the unlock command is transmitted by radio waves, the unlock command is transmitted by infrared rays. It is intended to be transmitted. FIG. 12 is a block diagram of a control system of the transmission / reception unit 2 provided in the circle lock 1 in the second embodiment. This block diagram is almost the same as the block diagram shown in FIG. 6, and the blocks with the same numbers as those in the block diagram of FIG. 6 have exactly the same functions. Description is omitted. The control system of FIG.
An infrared transmission circuit 67 is provided.
The unlock command output from the CPU 56 is converted into infrared light and output to the box lock 15. FIG. 13 is a block diagram of a control system of a receiving unit provided in the box lock 15 in the second embodiment. This block diagram is almost the same as the block diagram shown in FIG. 7, and the blocks with the same numbers as those in the block diagram of FIG. 7 have exactly the same functions. Description is omitted.

The control system shown in FIG.
This circuit receives the unlock command transmitted by infrared from the infrared transmitter circuit 67 of the circle lock 1 and outputs it to the CPU 57. in this way,
In the case where the unlock command is transmitted from the circle lock 1 to the box lock 15 by infrared rays, the positional relationship between the circle lock 1 and the box lock 15 may be problematic. This is because if there is a shield between the circle lock 1 and the box lock 15, the unlock command cannot be transmitted. Therefore, when using infrared rays, the installation position is set so that there is no shield between the circle lock 1 and the box-shaped lock 15.

In the present embodiment, only the first lock device, the circle lock 1, receives the release code having the ID code from the transmitter 30, and after the circle lock 1 is unlocked, it further transmits an unlock command to the second lock device. Since the infrared light is output to the box-shaped lock 15 as a locking device, a situation in which one of the locks cannot be unlocked near the transmission distance limit does not occur.
Unlocking of multiple locking devices is possible with only one transmitter, and operability and portability at unlocking can be maintained as before,
Cost increases can be minimized.

In the above embodiment, the circle lock 1 is attached to the rear wheel 10A and the box lock 15 is attached to the front wheel 10B. However, the circle lock 1 may be attached to both wheels, or both wheels may be attached. A box lock 15 may be attached.

Also, one first locking device 1 having a function of receiving a signal from the transmitter 30 and outputting an unlock command after unlocking is attached (for example, a rear wheel) and output from this lock. Multiple locks unlocked with an unlock command (for example,
Front wheel and handle lock)
Operability can also further improve anti-theft properties.

FIG. 14 is a schematic diagram showing a third embodiment of the bicycle locking device according to the present invention. The first embodiment transmits an unlock command by radio waves or the second embodiment transmits an unlock command by infrared rays. Unlike the two embodiments,
The actuator (motor) is moved via a harness 21.

FIG. 15 is a block diagram of a control system of the receiving unit 2 provided in the circle lock 1 in the third embodiment. This block diagram shows the box-shaped lock 1 of the front wheel 10B.
5 is substantially the same as the block diagram shown in FIG. 6 except that the motor drive circuit 59 for operating the actuator (motor) 18 of FIG. Since they have the same function, the description of the function of these blocks will be omitted.

In this embodiment, only the circle lock 1 as the first locking device receives a signal from the transmitter 30 and outputs a signal for driving the actuator (motor) of the box lock 15 through the harness 21. In this case, one of the locks cannot be unlocked near the transmission distance limit, and a plurality of locking devices can be unlocked with only one transmitter. The operability and portability at the time can be kept as usual, and the cost increase can be suppressed as much as possible.

In the above embodiment, after the transmitting / receiving unit 2 receives the unlock code having the ID code and the unlock detection switch 6 detects the unlocking of the first unlocking device 1, the transmitting / receiving unit 2 2 has been transmitted to the unlocking device 15, but when the transmitting / receiving unit 2 receives the unlocking code having the correct ID code, the transmitting / receiving unit 2
May transmit a release command to the second unlocking device 15.

[0047]

According to the bicycle locking device of the present invention, the command from the transmitter is received only by the first locking device and the command is transmitted to the second locking device. The situation that one of the locks cannot be unlocked does not occur, and multiple locking devices can be unlocked with only one transmitter, and the operability and portability at the time of unlocking remain the same as before. The cost can be reduced as much as possible.
