BACKGROUND OF THE INVENTION
The present invention relates to a bicycle lock suitable for theft prevention that is operated by remote operation and is locked when an authentication code matches.
[0002]
[Prior art]
In bicycles, various lock devices have been proposed and used for theft prevention. In recent years, due to the development of electronic technology, a lock device using a combination of transmission and reception devices has been proposed in the field of two-wheeled vehicles such as bicycles.
Examples thereof are those disclosed in JP-A-8-260784 and JP-A-10-196188.
In the former case, a manually locked lock can be unlocked with a normal manual key, or when an optical signal including an identification code set in advance corresponding to the lock is received from the transmitting means. Only the unlocking control signal is generated and the unlocking operation is performed in the lock on the receiving means side.
[0003]
In the latter case, the rotation of at least one of the front and rear wheels is blocked by the manual push-in of the lock bar, and is locked by transmitting a radio wave including an ID code from the transmission means side. The electromagnetic release valve is operated only when the ID code from the transmission means side is identified and matched on the lock side, and unlocking is performed by restoring the lock bar. is there.
[0004]
[Problems to be solved by the invention]
However, any of the conventional remote-operated bicycle locking devices configured in this way is configured such that locking is performed manually and only unlocking is performed by remote operation using light or radio waves. Has been.
This is because when locking is performed by remote control, the wheel usually comes into contact with the spokes during the locking operation of a locking mechanism such as a hook that enters between the spokes of the wheel to prevent the wheel from rotating. Since locking is impossible when stopped, locking is widely performed manually.
For this reason, even if the bicycle is run without making the hands unclean by turning the lock remotely, the lock mechanism, such as a bag soiled with mud, must be operated again with fingers. He had to be unsanitary.
[0005]
Therefore, the applicant can solve the problems in the conventional remote-operated bicycle locking device and can perform only the remote operation in both the locking operation and the unlocking operation. Bicycle lock devices (Japanese Patent Application No. 10-79136, Japanese Patent Application No. 10-313223, etc.) were proposed.
[0006]
The present invention further improves the bicycle locking device proposed by the applicant of the present application so that locking and unlocking can be manually performed even in the case of a battery shortage or an electric circuit failure in a remotely operated bicycle lock. The purpose is to provide a bicycle lock.
[0007]
