【発明の属する技術分野】
本発明は例えば６×４．５判一眼レフカメラに用いられるカメラ用三脚補助具に関するものである。
【０００２】
【従来の技術】
従来この種のカメラ用三脚補助具として、カメラ用三脚に取付部材を取付け、カメラの三脚用ネジ穴によりカメラを取付け可能な保持部材を横用や縦用等の数種類形成し、取付部材と数種類の保持部材とを着脱自在に設け、取付部材に横用や縦用の保持部材を着脱交換することにより三脚にカメラを横位置や縦位置に固定するようにしたものが知られている。
【０００３】
【発明が解決しようとする課題】
しかしながらこの従来構造の場合、取付部材に横用や縦用の保持部材を着脱交換する構造のため、位置変更が厄介であると共にカメラのレンズの中心軸がずれてしまうことになり、それだけ被写体に対してのカメラアングルをセットし直さなければならず、使用快適性に劣ることがあるという不都合を有している。
【０００４】
【課題を解決するための手段】
本発明はこれらの課題を解決することを目的とするもので、本発明のうちで、請求項１記載の発明は、カメラ用三脚に取付可能な取付部材と、カメラの三脚用ネジ穴によりカメラを取付け可能な保持部材とからなり、上記保持部材を該保持部材に取付けられたカメラのレンズの中心軸を中心として角度回動固定可能な角度回動機構を設けてなり、上記角度回動機構として、上記保持部材にカメラのレンズの中心軸を中心とする円弧状の案内溝部を設けると共に上記取付部材に該案内溝部に係合案内可能な案内ロールを設け、該取付部材に該保持部材の案内溝部の底面に圧接係止されて保持部材を任意の位置に位置固定可能なクランプネジからなる固定部材を設けてなることを特徴とするカメラ用三脚補助具にある。
【０００５】
又、請求項２記載の発明は、上記角度回動機構に上記保持部材を０度位置及び９０度位置に位置決め可能なストッパー部を設けてなることを特徴とするものであり、又、請求項３記載の発明は、上記保持部材にカメラの底面及び一方側面に当接可能な互いに９０度をなす二つの当接保持面を形成してなることを特徴とするものであり、又、請求項４記載の発明は、上記取付部材にカメラ用三脚の取付ネジに螺着可能な取付ネジ穴を形成し、上記保持部材にカメラの三脚用ネジ穴に螺着可能な取付ネジを設けてなることを特徴とするものである。
【０００６】
【発明の実施の形態】
