【発明の属する技術分野】
本発明は、例えば、ノート型と称されるパソコンやワープロなどにおける本体（第一部材）と開閉体（第二部材）とを起伏開閉自在に枢着するために使用されるヒンジ装置に関するものである。
【０００２】
【従来の技術及び発明が解決しようとする課題】
ノート型と称されるパソコンやワープロは、本体に対して開閉体（ディスプレイ部）がヒンジ装置を介して起伏開閉自在に設けられている。
【０００３】
また、従来からこのノート型機器には、開閉体を本体に伏した閉塞状態で開閉体が勝手に開いてしまうことがないように、この閉塞状態を維持する閉塞装置が組み込まれている。この閉塞装置としては、所謂ラッチと称されるロック・解除可能な装置が用いられることが一般的であり、開閉体を閉じるとこのラッチによって自動的に閉塞状態がロックされ、使用時にはこのラッチを解除することで開閉体を開くことができる構造となっている。
【０００４】
しかし、開閉体を開く際にラッチを解除することは以外と煩わしく、本発明者は、このラッチなどの閉塞装置を用いることなく本体と開閉体との閉塞状態を維持できないものかと着眼した。
【０００５】
そして、本発明者は、この着眼点に基づいて試行錯誤し商品開発を進めた結果、本体（第一部材）に対し開閉体（第二部材）を閉じた状態ではヒンジ装置に回動抵抗が生じるように構成することにより、閉塞装置を用いることなく本体（第一部材）に対し開閉体（第二部材）を閉塞状態に維持できて、開くときの煩わしいロック解除操作は不要となり、また、これにより閉じる手前の位置でも回動作動に抵抗が付与されて閉じる際の衝撃が極めて良好に緩衝されることになる画期的なヒンジ装置を完成させるに至った。
【０００６】
【課題を解決するための手段】
添付図面を参照して本発明の要旨を説明する。
【０００７】

【０００８】
また、前記枢着軸６に前記圧接部７として突起７Ａを設け、この突起７Ａが回動することで圧接する前記受部８を前記第一連結体３に突設したことを特徴とする請求項１記載のヒンジ装置に係るものである。
【０００９】
また、前記第一連結体３は板材により構成して、この板材の一端部に前記軸受部４を設け、この第一連結体３としての板材に軸受部４と並設状態となるようにして切り出し片９を形成し、この切り出し片９の先端部を屈曲形成してこの屈曲先端部を前記受部８とし、前記軸受部４に枢着される枢着軸６の軸着部分の近傍に前記圧接部７としてカム７を設けて、この軸受部４に枢着軸６を枢着した際カム７と前記受部８とが近接状態に配設されるように構成し、この枢着軸６の回動により圧接部７としてのカム７が回動すると、このカム７の偏心突起７Ａが近接する前記受部８に圧接するように構成したことを特徴とする請求項１，２のいずれか１項に記載のヒンジ装置に係るものである。
【００１０】
【発明の実施の形態】
好適と考える本発明の実施の形態（発明をどのように実施するか）を、図面に基づいてその作用効果を示して簡単に説明する。
【００１１】
第一部材１と第二部材２とが開いた状態から、第一部材１に対して第二部材２を閉じるように回動させると、第一部材１と第二部材２とが重合閉塞する手前の位置で、軸受部４若しくは枢着軸６に設けた圧接部７が第二連結体５若しくは前記第一連結体３に設けた受部８に圧接して枢着軸６に回動抵抗が生じる。
【００１２】
従って、閉じる手前で回動抵抗が生じるために、閉じた時の衝撃が極めて良好に緩衝されることになり、例えばノート型のパソコンやワープロなどのヒンジ装置として本発明品を使用すれば、勢い良く本体（第一部材１）に開閉体（第二部材２）が叩き付けられて破損したりすることが確実に防止されることになる。
【００１３】
この回動抵抗に抗して第一部材１若しくは第二部材２を手で動かせば、この第一部材１と第二部材２とを重合閉塞状態とすることができる。
【００１４】
また、この重合閉塞した状態の第一部材１と第二部材２とを開こうとする際にも、圧接部７が受部８に圧接して枢着軸６に回動抵抗が生じることとなる。
【００１５】
従って、簡単に第一部材１と第二部材２とが開いてしまうようなことはなく、圧接部７と受部８との圧接力により重合閉塞状態が維持されることになる。
【００１６】
この回動抵抗に抗して第一部材１若しくは第二部材２を手で動かせば、第一部材１と第二部材２とを開くことができる。
【００１７】
よって、例えば、ノート型のパソコンやワープロなどのヒンジ装置として本発明品を使用すれば、従来品のようにラッチなどの閉塞装置を用いることなく本体（第一部材１）に対し開閉体（第二部材２）を閉塞状態に維持できることになるので、これにより開くときの煩わしいロック解除操作は不要で、この回動抵抗に抗して第一部材１若しくは第二部材２を手で動かすだけの操作で第一部材１と第二部材２とを開くことができる開閉操作性に秀れた構造の製品を実現できることになる。
【００１８】
【実施例】
本発明の具体的な実施例について図面に基づいて説明する。
【００１９】
本実施例は、図１に示すようにノート型パソコンに適用した場合を示したもので、本体部を第一部材１とし、開閉部（ディスプレイ部）を第二部材２とし、本体部１と開閉部２とが重合した閉塞状態から開閉部２を回動起動した開放状態（使用状態）とすることができる枢着構造に本発明のヒンジ装置を適用している。尚、図面ではヒンジ装置をノート型パソコンの左右二箇所に設けた場合を示している。
以下、具体的に説明すると、図１〜図６は第一実施例（本発明の実施例）、図７は第二構成例を示している。
【００２０】
第一実施例について説明する。
【００２１】
本実施例は、本体部１の後部に連結される第一連結体３と、開閉部２の下部に連結される第二連結体５とを回動自在に枢着した構成としている。
【００２２】
具体的に説明すると、第一連結体３は、略長方形状を呈する板材（例えば金属板）により構成し、この板材の長さ方向の一端側（図２における上端側）をこの長さ方向に沿って三つに切断し、この三つの切り出し片９のうち、図３に示すように中央の切り出し片９の先端を円筒状に折曲形成してこの先端円筒部を軸受部４としている。
【００２３】
また、第二連結体５も、略長方形状を呈する板材（例えば金属板）により構成し、この板材の一端側（図２における下端側）に枢着軸６を、この枢着軸６の軸方向が第二連結体５の長さ方向と直交する方向となるようにして付設固定している。
【００２４】
そして、前記第一連結体３の筒状の軸受部４に、第二連結体５の枢着軸６を嵌挿することで第一連結体３に対して第二連結体５を回動自在に枢着した構成としている。
【００２５】
また、本実施例では、軸受部４と枢着軸６とに摩擦抵抗（回動抵抗）を生じる構成とし、この回動抵抗により本体部１に対して開閉部２を所望位置でストップできるフリーストップ構造を実現している。図中符号12は軸受部４と枢着軸６との間に介在するカラーである。
【００２６】
本実施例では、この枢着軸６にこの枢着軸６と共に回動する圧接部７を設け、この圧接部７が回動することで圧接する受部８を前記第一連結体３に設けて、この圧接部７と受部８との圧接力によって前記枢着軸６の回動作動に抵抗が生じるように構成している。
【００２７】
具体的に説明すると、軸受部４に軸支される枢着軸６のこの軸支部分の近傍に前記圧接部７を設けている。更に詳しくは、図２，図３に示すように、軸受部４を挟むようにして枢着軸６の二箇所に圧接部７を設け、この二箇所の圧接部７が、夫々前記第一連結体３の左右の切り出し片９に臨設するように構成している。
【００２８】

【００３０】
更に詳しくは、この左右の切り出し片９の先端部を断面略Ｖ字状に屈曲形成してこの屈曲先端部を前記受部８としている。
【００３１】
即ち、軸受部４に枢着軸６を枢着すると、カム７と受部８とが近接状態に配設されるように構成し、この枢着軸６の回動によりカム７が回動すると、このカム７の偏心突起７Ａが近接する前記受部８に圧接するように構成している。
【００３２】
また、この際、受部８としての屈曲切り出し片９の弾性により受部８と前記圧接部７との圧接状態が維持されて前記枢着軸６に回動抵抗が付与されると共に、この受部８の弾性による回動抵抗に抗して枢着軸６を回動し得るように構成している。
【００３３】
尚、本実施例では、上記のように受部８を第一連結体３に一体に設けた場合を示しているが、例えば第一連結体３に別の部材を付設し、この別部材に受部８を設けることで、第一連結体３から受部８を突設する構成としても良い。また、受部８は、図示した場合と逆方向に切り出し片９の先端部を屈曲形成して構成しても良いし、その他の構造としても良い。
【００３４】
また、本実施例では、前記本体部１に対し前記開閉部２が重合閉塞する手前の位置で受部８に圧接して枢着軸６に回動抵抗が生じ、又は重合閉塞した状態の本体部１に対して開閉部２を開こうとする際に受部８に圧接して枢着軸６に回動抵抗が生じるように構成している。
【００３５】
具体的には、図４に示すように本体部１に対して開閉部２が開いた状態では、全く圧接部（カム）７の突起７Ａが受部８に接触することがなく、この状態から、開閉部２を閉じるように回動させると、図５に示すように本体部１に開閉部２が完全に重合閉塞してしまう少し手前の位置で枢着軸６と共に回動するカム７の突起７Ａが受部８に圧接して前記枢着軸６に回動抵抗が生じるように、カム７の突起７Ａが存する位置を設定構成し、この回動抵抗に抗して本体部１に対し開閉部２を重合閉塞させることができるように構成している。
【００３６】
また、このような圧接部７と受部８との圧接構造とすることにより、図６に示すように回動抵抗に抗して重合閉塞している本体部１と開閉部２とを開く際にも必然的に圧接部７と受部８とが圧接して枢着軸６に回動抵抗を生じることになり、これにより簡単に開閉部２が開くことはなく、且つ例えば手で開くなどして開閉部２を動かすことで開閉部２を開放することができる構成としている。
【００３７】
図中符号10は本体部１と開閉部２に第一連結体３と第二連結体５とを固定するためのビス、11はビス穴である。
【００３８】
第二構成例について説明する。
【００３９】
本構成例は、前記第一実施例において、第一連結体３の一端側に設けた三つの切り出し片９のうち、左右の切り出し片９の先端を円筒状に折曲形成してこの左右の先端円筒部を軸受部４とし、中央の切り出し片９の先端部を断面略Ｖ字状に屈曲形成してこの屈曲先端部を受部８とした場合である。
【００４０】
また、この受部８の形成位置に対応して、前記枢着軸６には、左右の軸受部４に挟まれた中央部分の一箇所に圧接部７（カム）を設けている。
【００４１】
この第二構成例の構造によっても、前記第一実施例と同様の作用効果が得られる。
【００４２】
その他の構成は前記第一実施例と同様である。
【００４３】
尚、本発明は、本実施例に限られるものではなく、各構成要件の具体的構成は適宜設計し得るものである。
【００４４】
【発明の効果】
本発明は上述のように構成したから、第一部材と第二部材とを閉じる手前で回動抵抗が生じるために、閉じた時の衝撃が極めて良好に緩衝されることになり、また、重合閉塞した状態の第一部材と第二部材とを開こうとする際にも枢着軸に回動抵抗が生じることとなる。
【００４５】
従って、例えばノート型のパソコンやワープロなどのヒンジ装置として本発明品を使用した場合には、勢い良く本体（第一部材）に開閉体（第二部材）が叩き付けられて破損したりすることが確実に防止され、且つ重合閉塞状態が維持されて簡単には開かないので、実質的にラッチなどの閉塞装置は不要で開くときのロック解除操作が不要となる製品を実現できることになる極めて実用性に秀れた画期的なヒンジ装置となる。

DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the present invention (how to carry out the invention) considered to be suitable will be briefly described with reference to the drawings, showing its effects.
[0011]
When the first member 1 and the second member 2 are opened from the open state, the first member 1 and the second member 2 are closed by overlapping when the second member 2 is rotated relative to the first member 1. At the front position, the pressure contact portion 7 provided on the bearing portion 4 or the pivot shaft 6 is pressed against the receiving portion 8 provided on the second coupling body 5 or the first coupling body 3, and the pivot shaft 6 resists rotation. Occurs.
[0012]
Therefore, since a rotational resistance is generated before closing, the impact when closing is very well buffered. For example, if the product of the present invention is used as a hinge device of a notebook personal computer, word processor, etc. The opening / closing body (second member 2) is well hit against the main body (first member 1) and is reliably prevented from being damaged.

At this time, the elastic state of the bent cutout piece 9 as the receiving portion 8 maintains the pressure contact state between the receiving portion 8 and the pressure contact portion 7 so that a rotational resistance is applied to the pivot shaft 6, and The pivot shaft 6 can be turned against the turning resistance caused by the elasticity of the portion 8.
[0033]
In addition, in the present Example, although the case where the receiving part 8 was integrally provided in the 1st connection body 3 as mentioned above was shown, for example, another member is attached to the 1st connection body 3, and this separate member is attached to this separate member. It is good also as a structure which protrudes the receiving part 8 from the 1st coupling body 3 by providing the receiving part 8. FIG. Further, the receiving portion 8 may be configured by bending the tip end portion of the cut piece 9 in the direction opposite to that shown in the drawing, or may have another structure.
[0034]
Further, in this embodiment, the main body 1 is in a state where the opening / closing part 2 is pressed against the receiving part 8 at a position before the opening and closing of the opening / closing part 2 and a pivotal resistance is generated on the pivot shaft 6, or the body is in a closed state. When the opening / closing part 2 is to be opened with respect to the part 1, it is configured to press against the receiving part 8 and generate a rotational resistance on the pivot shaft 6.
[0035]
Specifically, as shown in FIG. 4, when the opening / closing part 2 is opened with respect to the main body part 1, the projection 7 </ b> A of the pressure contact part (cam) 7 does not contact the receiving part 8 at all. When the opening / closing part 2 is rotated so as to be closed, as shown in FIG. 5, the cam 7 is rotated together with the pivot shaft 6 at a position just before the opening / closing part 2 is completely overlapped with the main body 1. The position where the projection 7A of the cam 7 exists is set so that the projection 7A comes into pressure contact with the receiving portion 8 and a rotation resistance is generated in the pivot shaft 6, and against the rotation resistance, the body portion 1 is against the rotation resistance. The opening / closing part 2 is configured to be closed by polymerization.
[0036]
Further, by adopting such a pressure contact structure between the pressure contact portion 7 and the receiving portion 8, as shown in FIG. 6, when opening the main body portion 1 and the opening / closing portion 2 that are overlapped against the rotational resistance. However, the pressure contact portion 7 and the receiving portion 8 inevitably come into pressure contact with each other, and a pivotal resistance is generated on the pivot shaft 6, so that the opening / closing portion 2 is not easily opened and is opened by hand, for example. Thus, the opening / closing part 2 can be opened by moving the opening / closing part 2.
[0037]
In the figure, reference numeral 10 denotes a screw for fixing the first connecting body 3 and the second connecting body 5 to the main body 1 and the opening / closing part 2, and 11 denotes a screw hole.
[0038]
A second configuration example will be described.
[0039]
In this configuration example, in the first embodiment, among the three cutout pieces 9 provided on one end side of the first connecting body 3, the left and right cutout pieces 9 are bent at the tips of the left and right sides to form cylindrical shapes. This is a case where the tip cylindrical portion is the bearing portion 4, the tip portion of the cutout piece 9 at the center is bent into a substantially V-shaped cross section, and this bent tip portion is used as the receiving portion 8.
[0040]
Corresponding to the position where the receiving portion 8 is formed, the pivot shaft 6 is provided with a pressure contact portion 7 (cam) at one central portion sandwiched between the left and right bearing portions 4.
[0041]
Also according to the structure of the second configuration example, the same effects as those of the first embodiment can be obtained.
[0042]
Other configurations are the same as those in the first embodiment.
[0043]
The present invention is not limited to this embodiment, and the specific configuration of each component can be designed as appropriate.
[0044]
【The invention's effect】
Since the present invention is configured as described above, a rotational resistance is generated before the first member and the second member are closed, so that an impact when the first member is closed is extremely well buffered. When trying to open the first member and the second member in the closed state, a rotational resistance is generated on the pivot shaft.
[0045]
Therefore, for example, when the product of the present invention is used as a hinge device such as a notebook computer or word processor, the opening / closing body (second member) may be struck against the main body (first member) and damaged. Since it is reliably prevented and the polymerization blockage state is maintained and it does not open easily, a closure device such as a latch is substantially unnecessary, and it is possible to realize a product that requires no unlocking operation when opening. This is a revolutionary hinge device that excels in.
[0046]
Moreover, the present invention can easily design and realize the pressure contact structure between the pressure contact portion and the receiving portion that reliably exerts the above-described effects, and further, the receiving portion of the present invention is simply cut out from the plate material as the first coupling body. Since the configuration is such that the tip of the cut-out piece is simply formed by bending, the hinge device is more practical and can be configured very easily.
[0047]
In the invention of claim 2 Symbol mounting, the hinge apparatus Xiu is the more practical that enables design realize pressure structure between contact portion and the receiving portion to reliably exhibit the functions and effects easily.
[0048]
In the invention according to claim 3 , it is possible to easily design and realize the pressure contact structure between the pressure contact portion and the receiving portion that surely exerts the above-mentioned effects, and the pressure contact portion of the present invention is an eccentric cam on the pivot shaft. Since the receiving portion is simply formed by bending the tip of the cut piece cut out from the plate material, both of them can be configured very easily, and the hinge device is more practical.
