Description

本発明は、非使用時に自転車のサドルを直立状態とさせて、乗車できないようにすることによって、自転車の盗難を防止するようにした自転車の盗難防止装置に関する。   The present invention relates to a bicycle antitheft device that prevents the bicycle from being stolen by keeping the bicycle saddle upright when not in use.

従来、自転車を駐車させておく場合、前輪又は後輪のスポーク間に停止プレートを突出させたり、ダイヤル錠付ケーブルを掛止させたりして、前輪又は後輪が回転できないようにして、自転車が盗難されるのを防止していた。   Conventionally, when a bicycle is parked, the front plate or rear wheel cannot be rotated by protruding a stop plate between spokes of the front wheel or the rear wheel or by hooking a cable with a dial lock. It was prevented from being stolen.

しかし、ペンチ等を使用すれば、停止プレートは簡単に折曲でき、ダイヤル錠付ケーブルは簡単に切断でき、その後、自転車に乗車して安々と盗難することができる。   However, if a pliers or the like is used, the stop plate can be bent easily, the dial lock cable can be easily cut, and then the bicycle can be ridden on the bicycle for easy theft.

そこで、シートポストの上端部に鍵及び錠による盗難防止装置を設置して、非使用時に施錠することによって、サドルを直立状態に保持させて、乗車できないようにしたものが提案されている(例えば、特許文献1、特許文献2等参照。)。   Therefore, an antitheft device using a key and a lock is installed at the upper end of the seat post, and the saddle is locked up when not in use, so that the saddle is kept upright and cannot be boarded (for example, , Patent Document 1, Patent Document 2, etc.).
