Description

【０００１】
【発明の属する技術分野】
本発明は、第一部材と第二部材を枢着するヒンジ装置並びにヒンジ装置を用いた電子機器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】
本体部に対して蓋部を開閉できるようにヒンジ装置を用いて枢着した電子機器の典型例としては、例えばノート型パソコンがあるが、開閉する部材が回動途中でふらつかず、手を放して回動させることをやめたときその位置で回動停止するフリーストップが実現するようにすることが望ましい。
【０００３】
ところで、このノート型パソコンは近年益々小型化が進み、この小型化に伴い蓋部の厚さも薄くなっているが、蓋部が薄くなると、本体部に重合した閉じ状態においては、本体部と蓋部との間に指が掛けにくく開けにくいという問題が生じている。
【０００４】
そこで、本体部と蓋部との間に設けられた係止構造（ラッチ機構）の係止解除により、本体部に対して蓋部が所定回動角度まで開放方向に開き付勢されて自動開放する機能（所謂ポップアップ機能）を確実に達成し得るヒンジ装置の提案が望まれている。
【０００５】
しかしながら、このポップアップ機能を生じるために、開放方向に大きな開き付勢される付勢力を具備せしめると、フリーストップが実現できなくなる。
【０００６】
本出願人は、このような問題点に鑑み、例えば大きな回動抵抗を生じながらも、回動付勢（開放付勢）されなければならない回動位置では回動付勢が生じるように、前記回動抵抗が自動的に減少するように構成した画期的なヒンジ装置並びにヒンジ装置を用いた電子機器を提供することを目的としている。

【００１５】
【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。
【００１６】
枢着軸４は、第一連結部３を介して第一部材１と共に回動し、この枢着軸４に被嵌した軸受部６は、第二連結部５を介して第二部材２と共に回動する。
【００１７】
従って、例えば第二部材２に対して第一部材１を回動させると、軸受部６に対して枢着軸４が回動することとなる。
【００１８】
この際、軸受部６は断面Ｃ状で枢着軸４に締め付け被嵌されているため、この締め付け力による回動抵抗が生じ（この他、回動面（摩擦面）を工夫（加工））したり、他に摩擦や回動抵抗を生じさせる付勢機構を設けて回動抵抗が更に増加するように設計しても良い。）、この回動抵抗に抗して第二部材２に対して第一部材１を回動することとなる。
【００１９】
即ち、例えばこの軸受部６の径寸法の設定により回動抵抗を増減でき、この径寸法を小さくして締め付け力が増大するように設計することで、大きなトルク（回動抵抗）を生じるようにして開閉する部材（第一部材１）が重い部材でもフリーストップが実現するように設計することができる。
【００２０】
また、第二部材２に対する第一部材１の相対回動に際して、回動付勢体８による戻り回動方向に回動付勢力が生じるように構成され、更に、枢着軸４に軸断面径が径小となる径小部７を設け、この径小部７に軸受部６のＣ状端部６ａが位置して枢着軸４に対する軸受部６の締め付け力が減少する回動抵抗減少領域とし、この回動抵抗減少領域においては、前記回動付勢体８による戻り回動付勢力が前記枢着軸４に対する前記軸受部６の締め付け力による回動抵抗に勝るように構成している。
【００２１】
この回動抵抗減少領域を、例えば第一部材１と第二部材２とが重合する閉塞状態から所定開放角度までの開放状態となるようにした場合、第二部材２に対して第一部材１が回動付勢体８による戻り回動付勢力により開放方向に所定開放角度だけ回動することになる。
【００２２】
また、この回動抵抗減少領域以外の回動領域においては、前記枢着軸４に対する前記軸受部６の締め付け力による回動抵抗が前記回動付勢体８による戻り回動付勢力に勝り、第二部材２に対して第一部材１を手で開閉相対回動することができ、手を放して回動させることをやめたときその位置で回動停止するフリーストップ機能が発揮される。
【００２３】
従って、本発明は、回動付勢（開放付勢）させることができ、且つ回動時には大きな回動抵抗を生じさせることができる。言い換えると、例えば枢着軸４に対する軸受部６の締め付け力による回動抵抗が働いていても、回動付勢（開放付勢）されなければならない回動位置では、軸受部６のＣ状端部６ａが枢着軸４の径小部７に位置する回動抵抗減少領域となることで、自動的に回動抵抗が減少し、そのため、十分な開放付勢がなされる画期的なヒンジ装置となる。
【００２４】
【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。
【００２５】
本実施例は、図面に示すようにラップトップタイプのノート型パソコンＡに適用した場合のもので、ディスプレイ部１ａを備えた蓋部１を第一部材１とし、本体部２を第二部材２とし、この本体部２と蓋部１とが重合した閉塞状態から蓋部１を略１８０度程度まで回動した開放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Ｂを適用している（図１２参照）。本体部２に対して蓋部１を略１８０度回動するのは、例えば電車や自動車などの椅子に座った状態で膝の上に載せて使用する場合などである。
【００２６】
また、本実施例に係る本体部２と蓋部１との重合先端部位には、該本体部２と蓋部１との重合状態を係止保持するラッチ機構１０が設けられている。
【００２７】
本実施例では、図２〜４に図示したように第一部材１（蓋部）に連結する第一連結部３（連結金具）に枢着軸４を設け、第二部材２（本体部）に連結する第二連結部５（連結金具）に前記枢着軸４の基部に締め付け被嵌する断面Ｃ状の軸受部６を設けている。符号１１は補強ブラケット、１３はワッシャーである。尚、図２〜４は左用のヒンジ装置Ｂ、図５，６は右用のヒンジ装置Ｂであり同一構造である。
【００２８】
この軸受部６は、金属板材で構成した前記第二連結部５の端部をカールして断面Ｃ状の軸受部６とし、この軸受部６の径寸法を枢着軸４の基部径よりやや径小として、枢着軸４に締め付け被嵌するように構成して、フリーストップを実現するに十分なトルク（圧接による回動抵抗）が生じるように構成している。
【００２９】
また、本実施例では、軸受部６が締め付け被嵌する円柱状の枢着軸４の基部にして外周面長さ方向に平坦カット面を形成して径小部７が形成されており、この径小部７に軸受部６のＣ状端部６ａが位置して枢着軸４に対する軸受部６の締め付け力が減少する回動抵抗減少領域として構成されている。
【００３０】
具体的には、この回動抵抗減少領域は、第一部材１と第二部材２との枢着部９に本実施例を設けた際、図７に図示した第一部材１と第二部材２とが重合した閉塞状態から、図８に図示した第二部材２に対して第一部材１が所定開放角度（約３０度）まで回動した開放状態までの領域となるように構成されており、この回動抵抗の減少度合いは、後述する回動付勢体８による戻り回動付勢力が前記枢着軸４に対する前記軸受部６の締め付け力による回動抵抗に勝り、第二部材２に対して第一部材１が戻り回動付勢方向に自動回動する程度に設定されている。
【００３１】
回動付勢体８は、図示したように枢着軸４に被嵌されるコイルバネで構成され、その一端部は第二連結部５に連結され、他端部は枢着軸４の先端部に設けられた係止体１２に係脱可能に構成されている。
【００３２】
具体的には、枢着軸４を一方向へ回動させた際には係止体１２の係止部１２ａが係止して回動付勢体８による戻り回動付勢力に抗して回動する戻り付勢回動領域となり、他方向へ回動させた際には係止体１２の係止部１２ａによる係止が解除されて回動付勢体８による戻り付勢力が及ばない無付勢回動領域となるように構成されている。
【００３３】
更に具体的に説明すると、本実施例を第一部材１と第二部材２との枢着部９に設け、第一部材１と第二部材２の双方が重合した０度の閉塞状態（図１２中ａの状態）から第二部材２に対して第一部材１を略１８０度まで回動した開放状態（図１２中ｄの状態）にまで開閉できる状況において、０度から１２０度までの回動範囲においては、回動付勢体８に係止体１２が係止して枢着軸４が戻り回動付勢力を受ける付勢回動領域とし（図１１中ａの状態からｂの状態）、１２０度から１８０度までの回動範囲においては、回動付勢体８に対する係止体１２の係止が解除されて枢着軸４は戻り回動付勢力を受けない無付勢回動領域としている（図１１中ｃの状態からｄの状態）。
【００３４】
これは、第一部材１と第二部材２の双方が重合した閉塞状態から第二部材２に対して第一部材１を１２０度まで回動させた開放状態、即ち、通常の使用状態までは回動付勢体８の戻り回動付勢力を伴って楽に開放できるように機能し、１２０度から１８０度までは第一部材１の重さが加わっても手を放しても確実なフリーストップが機能するための構成である（例えばノート型パソコンの蓋部であればディスプレイ部の破損を防止することができる。）。
【００３５】
本実施例は上述のように構成したから、ラッチ機構１０による係止状態を解除すると、第二部材２に対して第一部材１は３０度開放方向に自動回動する。これは回動付勢体８による戻り回動付勢力によるもので、軸受部６のＣ状端部６ａが枢着軸４の径小部７に位置する回動抵抗減少領域にて回動抵抗よりも当該戻り回動付勢力が勝っているからである（これがポップアップ機能である。）。
【００３６】
続いて、第一部材１を３０度の所定開放角度から１２０度までの回動領域、即ち、前述した回動抵抗減少領域以外の回動領域では、回動付勢体８の戻り回動付勢力が効いて軽い回動が行われるものの、この戻り回動付勢力が回動抵抗よりも勝ることがないため確実なフリーストップ状態が達成される。
【００３７】
続いて、更に第一部材１を１２０度の所定開放角度から略１８０度までの回動領域では、回動付勢体８の戻り回動付勢力が効かない無付勢回動領域となり、回動抵抗だけが効いて強いフリーストップ状態が達成されることになる。
【００３８】
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。
【００３９】
【発明の効果】
本発明は上述のように構成したから、簡易な構成で大きな回動抵抗を生じながらも、回動付勢されなければならない回動位置では十分な回動付勢体による戻り回動付勢力が生じるように、回動抵抗が自動的に減少する画期的なヒンジ装置となる。
【００４０】
即ち、本発明は、回動時には枢着軸に対する軸受部の締め付け力で大きな回動抵抗を生じながらも、回動付勢されなければならない回動位置では、軸受部のＣ状端部が枢着軸の径小部に位置するように設定することで、自動的に回動抵抗が減少し、そのため、回動付勢体による十分な戻り回動付勢力が生じて回動付勢がなされる画期的なヒンジ装置となる。
【００４１】
また、請求項２〜４記載の発明においては、更に簡単な構成で本発明を容易に実現できる、或いは一層使い易くなるなど極めて実用性に秀れたヒンジ装置となる。
【００４２】
また、請求項５記載の発明においては、第一部材と第二部材との回動位置に応じて最良の機能を発揮する画期的なヒンジ装置となる。

[0002]
[Prior art and problems to be solved by the invention]
A typical example of an electronic device pivotally attached using a hinge device so that the lid can be opened and closed with respect to the main body is, for example, a notebook personal computer. It is desirable to realize a free stop that stops rotating at that position when the rotation is stopped.
[0003]
By the way, in recent years, the notebook personal computer has been increasingly reduced in size, and the thickness of the lid portion has been reduced along with the reduction in size. There is a problem that it is difficult to put a finger between the two parts and it is difficult to open.

Therefore, by releasing the locking structure (latch mechanism) provided between the main body and the lid, the lid is opened and urged in the opening direction up to a predetermined rotation angle with respect to the main body to automatically open. It is desired to propose a hinge device that can reliably achieve a function (so-called pop-up function).
[0005]
However, in order to produce this pop-up function, a free stop cannot be realized if a biasing force that is greatly biased in the opening direction is provided.
[0006]
In view of such a problem, the applicant of the present invention is, for example, that the rotation bias is generated at the rotation position where the rotation bias (open bias) must be generated while generating a large rotation resistance.

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.
[0016]
The pivot shaft 4 is rotated together with the first member 1 via the first connecting portion 3, and the bearing portion 6 fitted to the pivot shaft 4 is coupled with the second member 2 via the second coupling portion 5. Rotate.
[0017]
Therefore, for example, when the first member 1 is rotated with respect to the second member 2, the pivot shaft 4 is rotated with respect to the bearing portion 6.
[0018]
At this time, since the bearing portion 6 has a C-shaped cross section and is tightly fitted to the pivot shaft 4, a rotational resistance is generated by the tightening force (in addition, the rotational surface (friction surface) is devised (processed)). Alternatively, an urging mechanism that generates friction and rotational resistance may be provided to further increase the rotational resistance. ), The first member 1 is rotated with respect to the second member 2 against the rotation resistance.
[0019]
That is, for example, the rotational resistance can be increased or decreased by setting the diameter dimension of the bearing portion 6, and a large torque (rotation resistance) is generated by designing the diameter dimension to be small and the tightening force to be increased. Even if the member that opens and closes (the first member 1) is heavy, the free stop can be realized.
[0020]
Further, when the first member 1 is relatively rotated with respect to the second member 2, a rotation urging force is generated in the return rotation direction by the rotation urging body 8. Is provided with a small-diameter portion 7 having a small diameter, and a C-shaped end portion 6a of the bearing portion 6 is positioned in the small-diameter portion 7 so that the tightening force of the bearing portion 6 with respect to the pivot shaft 4 is reduced. In this rotation resistance decreasing region, the return rotation biasing force by the rotation biasing body 8 is configured to overcome the rotation resistance due to the tightening force of the bearing portion 6 with respect to the pivot shaft 4. .
[0021]
For example, when the rotation resistance decreasing region is in an open state from a closed state in which the first member 1 and the second member 2 are superposed to a predetermined open angle, the first member 1 is in relation to the second member 2. Is rotated by a predetermined opening angle in the opening direction by the return turning biasing force of the turning biasing body 8.
[0022]
Further, in a rotation area other than the rotation resistance reduction area, the rotation resistance due to the tightening force of the bearing portion 6 with respect to the pivot shaft 4 is superior to the return rotation urging force by the rotation urging body 8. The first member 1 can be opened and closed relative to the second member 2 by hand, and when the hand is released and stopped rotating, the free stop function of stopping the rotation at that position is exhibited.
[0023]
Therefore, according to the present invention, the rotation can be biased (open bias), and a large rotation resistance can be generated during the rotation. In other words, the C-shaped end of the bearing portion 6 is at a rotational position where it must be biased (open biased) even if, for example, a rotational resistance is exerted by the tightening force of the bearing portion 6 with respect to the pivot shaft 4. The rotation resistance is automatically reduced by the portion 6a becoming a rotation resistance decreasing region located in the small diameter portion 7 of the pivot shaft 4, and therefore, a revolutionary hinge that is sufficiently opened and biased. It becomes a device.
[0024]

Specific embodiments of the present invention will be described with reference to the drawings.
[0025]
In this embodiment, as shown in the drawing, the present invention is applied to a laptop-type notebook computer A. The lid 1 having the display 1a is used as the first member 1, and the main body 2 is used as the second member 2. The hinge device B of the present invention is applied to a pivoting structure that can change the closed portion 1 from the closed state in which the main body portion 2 and the lid portion 1 are superposed to about 180 degrees. (See FIG. 12). The lid portion 1 is rotated approximately 180 degrees with respect to the main body portion 2 when, for example, the lid portion 1 is used on a knee while sitting on a chair such as a train or an automobile.
[0026]
In addition, a latch mechanism 10 that locks and holds the superposition state of the main body 2 and the lid 1 is provided at the polymerization tip portion of the main body 2 and the lid 1 according to the present embodiment.
[0027]
In this embodiment, as shown in FIGS. 2 to 4, a pivot shaft 4 is provided on the first connecting portion 3 (connecting bracket) connected to the first member 1 (lid portion), and the second member 2 (main body portion). A bearing portion 6 having a C-shaped cross section that is fastened and fitted to the base portion of the pivot shaft 4 is provided in a second connecting portion 5 (connecting metal fitting) that is connected to the shaft. Reference numeral 11 is a reinforcing bracket, and 13 is a washer. 2 to 4 are the left hinge device B, and FIGS. 5 and 6 are the right hinge device B, which have the same structure.
[0028]
This bearing portion 6 curls the end of the second connecting portion 5 made of a metal plate material to form a bearing portion 6 having a C-shaped cross section, and the diameter of the bearing portion 6 is slightly larger than the base diameter of the pivot shaft 4. As the diameter is small, it is configured to be tightly fitted to the pivot shaft 4 so that sufficient torque (rotation resistance due to pressure contact) is generated to realize a free stop.
[0029]
Further, in this embodiment, a small cut portion 7 is formed by forming a flat cut surface in the length direction of the outer peripheral surface at the base of the columnar pivot shaft 4 to which the bearing portion 6 is tightly fitted. The C-shaped end portion 6a of the bearing portion 6 is positioned in the small diameter portion 7 and is configured as a rotation resistance decreasing region in which the tightening force of the bearing portion 6 with respect to the pivot shaft 4 is reduced.
[0030]
Specifically, the rotation resistance decreasing region is formed by the first member 1 and the second member illustrated in FIG. 7 when the present embodiment is provided in the pivoting portion 9 between the first member 1 and the second member 2. 2 and the second member 2 illustrated in FIG. 8, the first member 1 is configured to be in a region from the closed state in which the first member 1 is rotated to a predetermined opening angle (about 30 degrees). The degree of decrease in the rotation resistance is such that the return rotation biasing force by the rotation biasing body 8 to be described later is superior to the rotation resistance due to the tightening force of the bearing portion 6 with respect to the pivot shaft 4, and the second member 2. In contrast, the first member 1 is set so as to automatically rotate in the return rotation urging direction.
[0031]
The rotation urging body 8 is constituted by a coil spring fitted to the pivot shaft 4 as shown in the figure, one end of which is coupled to the second coupling portion 5 and the other end is the tip of the pivot shaft 4. It is comprised so that engagement / disengagement to the latching body 12 provided in this is possible.
[0032]
Specifically, when the pivot shaft 4 is rotated in one direction, the locking portion 12a of the locking body 12 is locked and resists the return rotation biasing force by the rotation biasing body 8. It becomes a return urging rotation region that rotates, and when it is rotated in the other direction, the engagement by the engagement portion 12a of the engagement body 12 is released and the return urging force by the rotation urging body 8 does not reach. It is comprised so that it may become a non-biasing rotation area | region.
[0033]
More specifically, this embodiment is provided in the pivot joint 9 between the first member 1 and the second member 2, and a closed state of 0 ° (FIG. 5) in which both the first member 1 and the second member 2 are superposed. 12 in a state in which the first member 1 is rotated up to about 180 degrees relative to the second member 2 in the open state (the state in FIG. 12 d). In the rotation range, the engagement body 12 is engaged with the rotation urging body 8 and the pivot shaft 4 returns to the urging rotation area that receives the rotation urging force (from the state of FIG. State), in the rotation range from 120 degrees to 180 degrees, the engagement of the engagement body 12 with respect to the rotation urging body 8 is released, and the pivot shaft 4 does not receive the return rotation urging force. The rotation region is set (from the state c to the state d in FIG. 11).
[0034]
This is from the closed state where both the first member 1 and the second member 2 are overlapped to the open state where the first member 1 is rotated by 120 degrees with respect to the second member 2, that is, until the normal use state. It functions so that it can be opened easily with the return biasing force of the pivoting biasing body 8, and it is a reliable free stop from 120 degrees to 180 degrees even if the weight of the first member 1 is added or released. (For example, if it is a cover part of a notebook personal computer, the display part can be prevented from being damaged.).
[0035]
Since the present embodiment is configured as described above, when the latching state by the latch mechanism 10 is released, the first member 1 is automatically rotated by 30 degrees in the opening direction with respect to the second member 2. This is due to the return rotation urging force of the rotation urging body 8, and the C-shaped end portion 6 a of the bearing portion 6 is in the rotation resistance decreasing region located at the small diameter portion 7 of the pivot shaft 4. This is because the return rotation urging force wins (this is a pop-up function).
[0036]
Subsequently, in the rotation region where the first member 1 is rotated from a predetermined opening angle of 30 degrees to 120 degrees, that is, in the rotation area other than the rotation resistance reduction area described above, the rotation biasing body 8 is provided with a return rotation. Although the force is effective and light rotation is performed, the return rotation biasing force does not exceed the rotation resistance, so that a reliable free stop state is achieved.
[0037]
Subsequently, when the first member 1 is further rotated from a predetermined opening angle of 120 degrees to approximately 180 degrees, it becomes an unbiased rotation area where the return rotation urging force of the rotation urging body 8 does not work. Only dynamic resistance works and a strong free stop state is achieved.
[0038]
Note that the present invention is not limited to this embodiment, and the specific configuration of each component can be designed as appropriate.
[0039]
【The invention's effect】
Since the present invention is configured as described above, the return rotation biasing force by the sufficient rotation biasing body is sufficient at the rotation position where the rotation bias must be generated while generating a large rotation resistance with a simple configuration. As a result, it becomes a revolutionary hinge device in which the rotational resistance is automatically reduced.
[0040]
That is, according to the present invention, the C-shaped end portion of the bearing portion is pivoted at a rotational position where the rotational force must be biased while a large rotational resistance is generated by the tightening force of the bearing portion with respect to the pivot shaft during rotation. By setting it so that it is located in the small diameter portion of the shaft, the rotational resistance is automatically reduced, so that a sufficient return rotational biasing force is generated by the rotational biasing body, and the rotational bias is made. This is a revolutionary hinge device.
[0041]
Further, in the inventions according to claims 2 to 4, the present invention can be easily realized with a simpler configuration, or can be used more easily.
[0042]
Further, in the invention described in claim 5, it becomes an epoch-making hinge device that exhibits the best function according to the rotational position of the first member and the second member.
