Abstract
Description
本発明は、複写機やMFP(多機能周辺機器)の原稿圧着板などの開閉部材を開閉するための小型ヒンジに関するものである。 The present invention relates to a small hinge for opening and closing an opening / closing member such as a document pressure plate of a copying machine or an MFP (multifunctional peripheral device).
近年、複写機やMFPなどのヒンジはローコスト化や小型化の傾向にあり、2個のヒンジのうち片方のヒンジにのみ高荷重のバネを仕込んで、他方のヒンジはバネ無しの簡単なものを組み合わせるのが主流になりつつある。
この種の小型ヒンジとして、従来、図3(A)に示すように、ヒンジ本体1のブラケット部1aに回転軸2を介して支持部材3を回転自在に取り付けると共に、上記ヒンジ本体1内に摺動自在に設けたスライダー4内に圧縮金属バネ5を収容して、該スライダー4のカム面4aを上記支持部材3の回転カム部3aに当接せしめ、前記圧縮金属バネ5により支持部材3を、図3(B)のように回動せしめて、開閉部材Kを開くように構成した小型ヒンジがあった。
In recent years, hinges for copiers and MFPs have been declining in cost and size, and only one of the two hinges is loaded with a high-load spring, and the other hinge is a simple one without a spring. The combination is becoming mainstream.
As a small hinge of this type, conventionally, as shown in FIG. 3A, a
しかし、上記従来の小型ヒンジは、図3(B)のように開閉部材Kを開いた時に、圧縮金属バネ5により支持部材3が勢いよく回転して、安定した回転トルクが得られないため、該支持部材3やヒンジ本体1が損傷・破損する恐れがあった。
However, in the conventional small hinge, when the opening and closing member K is opened as shown in FIG. 3B, the
本発明が解決しようとする課題は、開閉部材Kを開いた時に確実かつ安定した回転トルクが得られ、支持部材3やヒンジ本体1が損傷・破損する恐れのない小型ヒンジを提供することにある。
The problem to be solved by the present invention is to provide a small hinge that can obtain a reliable and stable rotational torque when the opening / closing member K is opened, and does not cause damage or breakage of the
本発明の小型ヒンジは、複写機等の機器本体に取り付けられたヒンジ本体に回転軸を介して支持部材を回転自在に取り付けると共に、上記ヒンジ本体内に摺動自在に設けたスライダー内に弾性体を収容して、該スライダーのカム面を上記支持部材の回転カム部に当接せしめ、前記弾性体により支持部材を回動せしめて、該支持部材に取り付けられた開閉部材を開くように構成したヒンジにおいて、上記支持部材に弾性摩擦部を弾性的に撓むように形成し、該支持部材を回転させて開閉部材を開いた時に、上記弾性摩擦部がヒンジ本体の当接部に弾性的に当接するように構成したことを特徴とする。 The small hinge of the present invention has a support member rotatably attached to a hinge body attached to an apparatus body such as a copying machine via a rotation shaft, and an elastic body in a slider provided slidably in the hinge body. The slider cam surface is brought into contact with the rotating cam portion of the support member, the support member is rotated by the elastic body, and the opening / closing member attached to the support member is opened. In the hinge, the elastic friction portion is formed on the support member so as to be elastically bent, and when the opening and closing member is opened by rotating the support member, the elastic friction portion elastically contacts the contact portion of the hinge body. It is configured as described above.
本発明の小型ヒンジは、開閉部材を開いた時に確実かつ安定した回転トルクが得られ、支持部材やヒンジ本体が損傷・破損する恐れのない利点がある。 The small hinge of the present invention has an advantage that a reliable and stable rotational torque can be obtained when the opening and closing member is opened, and the support member and the hinge body are not damaged or broken.
以下、本発明の一実施例について、図面を参照しながら説明する。
図1は、上記図3に示す従来の小型ヒンジを改良した実施例を示すものであって、1はヒンジ本体、2は回転軸、3は支持部材、4はスライダー、5は圧縮金属バネ等の弾性体である。
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 shows an improved embodiment of the conventional small hinge shown in FIG. 3, wherein 1 is a hinge body, 2 is a rotating shaft, 3 is a support member, 4 is a slider, 5 is a compression metal spring, and the like. It is an elastic body.
上記ヒンジ本体1は、複写機等の機器本体Mに挿設状態で取り付けられており、該機器本体Mから突出しているブラケット部1aに回転軸2を介して支持部材3が回動自在に取り付けられている。該支持部材3には圧着板等の開閉部材Kが取り付け固定されている。
The
上記ヒンジ本体1内にはスライダー4が上下方向に摺動自在に納められていて、ヒンジ本体1とスライダー4の間に2重の圧縮バネ5が介挿されている。上記スライダー4の外端面にはカム面4aが形成されている。該カム面4aは上記支持部材3に設けられた回転カム部3aに弾性的に当接していて、上記弾性体5の反発力により、開閉部材Kをその重量に抗して回転させ、図2に示すように、開くように作用する。
A
6は弾性摩擦部であって、上記支持部材3に弾性的に撓むように形成されている。従って、図2に示すように、支持部材3を回転させて開閉部材Kを開いた時に、上記弾性摩擦部6がヒンジ本体1の当接部1bに弾性的に当接して、支持部材3に確実かつ安定した摩擦トルクが生じるようになっている。
Reference numeral 6 denotes an elastic friction portion, which is formed on the
本発明の小型ヒンジは、複写機のほかに、スキャナー、ファックス、これらの複合機(MFP)、洋式トイレなど、開閉部材を有し、これを弾性的に開く構造のヒンジであれば、いずれでもよい。 In addition to the copying machine, the small hinge of the present invention has an opening / closing member such as a scanner, a fax machine, a multi-function machine (MFP), a Western-style toilet, etc. Good.
