Description
【０００１】
【発明の属する技術分野】
本発明は、ノート型パソコン等の開閉部分に設けられるヒンジに関する。
【０００２】
【従来の技術】
従来のこの種のヒンジとしては、図３に示すように、ディスプレイ等の開閉部材を取り付けた回転軸Ｓを、機器本体に取り付けた保持プレートＰのカール部により包囲し、該保持プレートＰの延長部を締付けネジＮにより調節自在に締め付けて、該保持プレートＰにより回転軸Ｓを所望の摩擦トルクで回転自在に保持するようになっていた。
【０００３】
【発明が解決しようとする課題】
しかしながら、上記従来のヒンジは、保持プレートＰのカール部の細部形状が、材料板厚のバラツキやプレス機へのセッティングの状況により、生産ロット間でバラツキが生じてトルク発生部の面接触が均一になりにくく、トルク調整時にネジＮの締め付けトルクを一定にしても、発生トルクが一定にならず、その結果、ネジ締めの微調整が必要になるだけでなく、耐久性能にもバラツキが生じ易い等の問題点があった。
【０００４】
本発明は、上記従来の問題点を解決するためになされたもので、その目的とするところは、発生トルクや耐久性能を一定かつ安定せしめることができるヒンジを提供することにある。
【０００５】
【課題を解決するための手段】
本発明のヒンジは、機器本体に取り付けられる支持部材と、該支持部材に回転自在に取り付けられる回転軸と、該回転軸にしかもその軸方向に傾動可能に取り付けられる環状フリクション部と該環状フリクション部から放射方向に一体的に延設される受圧部から構成されると共に、該受圧部に最も近い側と最も遠い側の穴壁面部分が上記回転軸と摩擦係合する複数枚のフリクション傾斜プレートと、これらのフリクション傾斜プレートを傾動せしめて回転軸と摩擦係合せしめるように上記受圧部を押圧する押圧手段から構成されることを特徴とするヒンジ。
また、上記押圧手段が、上記支持部材に螺着されたネジ軸であって、フリクション傾斜プレートへの押圧力を調節可能に設けられていることを特徴とする。
【０００６】
【発明の実施の形態】
以下、本発明の実施の形態について、図面を参照しながら説明する。
図１において、１は支持部材、２は回転軸、３はフリクション傾斜プレート、４は押圧ネジである。
【０００７】
上記支持部材１は、機器本体（図示せず）に取り付けられる固定部１ａと、上記回転軸２を回転自在に取り付ける軸受部１ｂから構成されている。
上記回転軸２は段付き軸となっていて、先端部はＥリング（図示せず）等の抜け止め手段により止められている。
【０００８】
上記フリクション傾斜プレート３は、図２に示すように、環状フリクション部３ａと、該環状フリクション部３ａから放射方向に一体的に延設される受圧部３ｂから構成されている。該フリクション傾斜プレート３は、少なくとも２枚重ねた状態で上記回転軸２に取り付けられる。上記環状フリクション部３ａは、上記回転軸２にしかもその軸方向に傾動可能に取り付けられる。
【０００９】
上記実施例のヒンジは以上のように構成されているので、押圧ネジ４をねじ込むことにより、上記フリクション傾斜プレート３の受圧部３ｂを押すと、図２に示すように、該受圧部３ｂと一体となった環状フリクション部３ａが、上記回転軸２に対して傾動する。該環状フリクション部３ａが傾動すると、該環状フリクション部３ａの穴壁面のうち、特に上記受圧部３ｂに最も近い側Ｆ１と最も遠い側Ｆ２の穴壁面部分が上記回転軸２と摩擦係合する。この摩擦力は、上記押圧ネジ４による受圧部３ｂに対する押圧力に比例する。従って、該押圧ネジ４をねじ込むことにより、その押圧力を調整し、上記摩擦力を調整することができる。なお、本発明における押圧手段は、上記押圧ネジ４に限定するものではなく、上記環状フリクション部３ａを傾動させるものであれば、いずれの部材でもよい。
【００１０】
【発明の効果】
１）機器本体に取り付けられる支持部材と、該支持部材に回転自在に取り付けられる回転軸と、該回転軸に傾動可能に取り付けられる複数枚のフリクション傾斜プレートと、これらのフリクション傾斜プレートを傾動せしめるように押圧する押圧手段から構成されるので、発生トルクや耐久性能を一定かつ安定せしめることができる。
２）押圧手段が、支持部材に螺着されたネジ軸であって、フリクション傾斜プレートへの押圧力を調節可能に設けられているので、容易かつ迅速にトルク摩擦力を調節することができる。

BACKGROUND OF THE INVENTION
The present invention relates to a hinge provided at an opening / closing part of a notebook computer or the like.
[0002]
[Prior art]
As a conventional hinge of this type, as shown in FIG. 3, a rotating shaft S to which an opening / closing member such as a display is attached is surrounded by a curled portion of a holding plate P attached to the apparatus body, and the holding plate P is extended. The portion is tightened by a tightening screw N so as to be adjustable, and the rotating shaft S is rotatably held by a desired friction torque by the holding plate P.
[0003]
[Problems to be solved by the invention]
However, in the above conventional hinge, the detailed shape of the curled portion of the holding plate P varies between production lots due to variations in material plate thickness and setting to the press machine, and the surface contact of the torque generating portion is uniform. Even if the tightening torque of the screw N is constant at the time of torque adjustment, the generated torque is not constant. As a result, not only fine adjustment of the screw tightening is required, but also the durability performance is likely to vary. There was a problem such as.
[0004]
The present invention has been made to solve the above-described conventional problems, and an object of the present invention is to provide a hinge that can stabilize and stabilize the generated torque and durability.
[0005]
[Means for Solving the Problems]
The hinge of the present invention includes a support member attached to the apparatus main body, a rotation shaft rotatably attached to the support member, an annular friction portion attached to the rotation shaft and tiltable in the axial direction, and the annular friction portion. together consists pressure receiving portion which is integrally extend radially from, a plurality friction tilt plate of the closest and farthest hole wall portion of the said pressure receiving portion is frictionally engaged with the rotating shaft , hinges, characterized in that they are composed of a pressing means for pressing the pressure receiving portion to frictionally fit tighten so that the rotation axis brought tilting these friction tilt plate.
Further, the pressing means is a screw shaft screwed to the support member, and is provided so that the pressing force to the friction inclined plate can be adjusted.
[0006]
