Description

【０００１】
【発明の属する技術分野】
この発明は、自転車の後部に備えるキャリアを兼用できるようにした自転車用錠に関し、錠前のロッドをキャリアを構成するロッドに兼用させるようにしたことを特長とするものである。
【０００２】
従来、キャリアと自転車用錠を一体に備えるようにした自転車用錠には、例えば実開昭６３−４２４８３号公報と登録実用新案第３００２５０９号公報とがある。
【０００３】
実開昭６３−４２４８３号公報の錠前は、キャリアの後部に設けた取付け部にロックの錠本体部分をねじ止めして、ワイヤー錠をキャリアの後部裏面に垂下し、キャリアに取り付けたままの錠本体から錠杆部を着脱して施錠したり、非施錠状態に保持させたりして使用するようにしたものである。
この錠前には、非使用時に、長尺のワイヤー部分が垂下してその保持が難しいとともに、施錠、開錠操作がキャリアの後部裏面に限られるので操作し難いという欠点がある。
【０００４】
また、登録実用新案第３００２５０９号公報の錠前は、シャックルロックを非使用時にキャリアの荷台面に沿って保持させておくようにしたものである。
この錠前には、別体に備えたシャックルロックを非使用時に保持させるために、キャリアに余分な構造を付設する必要があって、構造が複雑になり、実用性に欠ける欠点がある。
そのために、施錠、開錠操作が容易にでき、キャリアの構造を複雑化しないで、キャリアと錠前を兼用できるようにすることが課題となっていた。
【０００５】
【課題を解決するための手段】
そこで本発明は、車体の後部の長さ方向に沿ってキャリアの支承面を形成するように互いに適宜の長さと間隔を隔てる２本のロッドの一端を連結ピンで左右に開閉自在に枢着して、該枢着部分を２本のロッド基端部とし、一方のロッドの先端部に、内蔵した施錠機構の施錠穴を端面に開口させた錠本体を内向きに一体に設け、他方のロッドの先端部に、上記錠本体の施錠穴に嵌合して施錠される錠杆部を設けて、この錠本体と錠杆部の施錠、開錠によって上記２本のロッドの先端部を開閉可能に連結し、車体の前後に設けたキャリアの取付け部の一方に、上記２本のロッドの基端部を枢着して、前記連結ピンにより連結された２本のロッドを後部タイヤの両側に垂下できるように取り付ける一方、他方の取付け部に、施錠状態に結合している錠本体と錠杆部と共にロッドの先端部を支承させて、上記前後の取付け部間に横架した２本のロッドにキャリア支承面を形成させるとともに、取付け部に支承されていた上記錠本体と錠杆部を開錠して、２本のロッドの先端部を後部タイヤの両側に垂下して後部タイヤを施錠させるように構成した自転車用錠において、前記キャリアの前部取付け部をサドルの下方に設け、この前部取付け部を車体の後方に向けて延長して、その先端に前記後部取付け部を設け、上記前部取付け部に前記２本のロッドの基端部を枢着するとともに、前記連結ピンにギヤを取り付けて、上記２本のロッドを左右に開閉するように備え、上記後部取付け部に設けた支承部に上記２本のロッドを嵌合させて、該ロッドの先端部と共に、施錠状態に結合させた上記錠本体と錠杆部を支承させてキャリアを形成させ、この後部取付け部の支承部に支承させていた錠本体と施錠杆を開錠して２本のロッドの先端部と共に後部タイヤの両側に垂下させて該タイヤを施錠させるように構成したことを特徴とする自転車用錠を提供するものである。
【０００６】
本発明自転車用錠は、錠前の非使用時に、基端部をキャリアの前部の取付け部に軸支させ、前部の取付け部から延長された後部取付け部の支承部に、先端部に備えた錠本体と錠杆部を施錠状態に結合させて縦長の環状体を形成する２本のロッドの中間部分を支承させ、横架することにより、キャリアの支承面を形成させる一方、施錠状態で支承されていた錠本体と錠杆部を開錠し、２本のロッドを左右に開いてロッドの先端部と共に後部タイヤの両側に垂下させて後部タイヤを施錠させるようにする。本発明自転車用錠は、このようにして比較的に長尺の２本のロッドを有する自転車用錠を錠前とキャリアとに兼用させるようにしたものである。。
なお、２本のロッドの基端部の連結ピンに備えたギヤは、上記のようにしてロッドを左右に開くときに互いに回転を伝動するので、一方のロッドを開けば他方のロッドも従動して、片側だけでも左右同時に開くことになる。
【０００７】
以上のように、本発明は、自転車用錠を錠前とキャリアの枠組みとの２様の機能を兼用するように構成したので、機能を複雑化することなく車体に一体に備えられた自転車用錠を提供することができ、かつ、その施錠と開錠の操作も容易にできる。本発明は，以上のようにして前記の課題を解決したものである。
【０００８】
【実施例】
図示のように、長さ方向に沿ってキャリアの支承面を形成するように互いに適宜の長さと間隔を隔てる２本のロッド９、９の一端（図示右手）を連結ピン２、２’で左右に開閉自在に枢着して、該枢着部分を２本のロッドの基端部１ａ、１ｂとし、一方のロッド９の先端部３に、内蔵した施錠機構の施錠穴を端面に開口させた錠本体４を内向きに一体に設け、他方のロッド９の先端部５に、錠本体４の施錠穴（図示省略）に嵌合して施錠される錠杆部６を設けて、この錠本体４と錠杆部６の施錠、開錠によって上記２本のロッドの先端部３、５を開閉可能に連結し、キャリアの大きさに対応する縦長の環状体を形成する。
【０００９】
一方、自転車のサドルの下方で車体Ｂに前部取付け部７を設け、この前部取付け部７を車体Ｂの後方に向けて延長して、その先端に後部取付け部８を設け、この後部取付け部８に設けた支承部１４に上記２本のロッドの中間部分を嵌合させるとともに、上記錠本体４と錠杆部６を施錠状態に結合させ、上記ロッドの先端部３、５と共に、縦長のキャリアの支承面を形成させる。
【００１０】
図１に示すようにキャリアとしての使用状態から、この錠前を図２に示すように自転車用錠として使用する場合には、後部取付け部８の支承部１４に支承させていた錠本体４と錠杆部６を開錠し、基端部１ａ、１ｂをそれぞれ連結ピン２、２’を支点にしてロッド９、９を左右に開き、次いで基端部１ａ、１ｂを取り付けたブラケット１５を支持する横軸１６を支点としてロッド９、９を後部タイヤＴの両側に垂下する。
【００１１】
上記ロッド９、９の基端部１ａ、１ｂを連結する連結ピン２、２’には、それぞれギヤ１３が取り付けられていて、一方のロッド９を開けばギヤ１３に伝動されて他方のロッド９も拡開するように構成されている。
【００１２】
【発明の効果】
以上のように、本発明は、自転車に一体に取り付けた錠前を、簡単な操作でキャリアに替えたり、自転車用錠に使用することができる。また、その取り付け構造もシンプルである。本発明には、以上のように優れた効果がある。
