Description

本発明は、ノートパソコン等の電子機器に適用される二軸ヒンジ装置に関する。更に詳しくは、2つの筐体を有するノートパソコン等の折り畳み開閉を360度の揺動を可能にする電子機器等に対応可能な二軸ヒンジ装置に関する。   The present invention relates to a biaxial hinge device applied to an electronic device such as a notebook computer. More specifically, the present invention relates to a biaxial hinge device compatible with electronic devices and the like capable of swinging 360 degrees of folding and opening and closing of a notebook computer and the like having two housings.

一般的なノート型のパーソナルコンピュータ(以下、「ノートパソコン」という。)は、キーボード部を設けた筐体と、ディスプレイ部を設けた筐体で構成され、双方はヒンジ装置を介して結合され折り畳み開閉ができる構造のものが主流である。即ち、2つの筐体は、このヒンジ装置を介して回動することで開閉するようになっている。このヒンジ装置は、2つの筐体に跨って端部側に対の構造で設けられているものが多く、既に多種の構造のものが知られ公知である。   A general notebook personal computer (hereinafter referred to as a "notebook personal computer") comprises a housing provided with a keyboard unit and a housing provided with a display unit, both of which are connected via a hinge device and folded The mainstream is the one that can be opened and closed. That is, the two housings are opened and closed by pivoting through the hinge device. Many of the hinge devices are provided in a pair structure on the end side straddling two housings, and those having various structures are already known and known.

このヒンジ装置の主な構造としては、1軸式と2軸式とがある。1軸式は、構造は単純化できるが2つの筐体を開閉させる角度に制約がある。2軸式は、1軸式に比し多少構造は複雑になるものの開閉角度に制約がない。この2軸式は、2つの軸を介して開閉させる構造のもので、2軸の各軸構造物が回転すると同時にヒンジ部全体も回転する構造になっている。この2軸式は平行する2軸間に距離があり開閉角の余裕代が生ずることから360度の開閉も可能となっている。   Main structures of this hinge device include a single-axis type and a two-axis type. The single-axis type can simplify the structure but has a restriction on the angle at which the two housings are opened and closed. The two-axis type is somewhat complicated in structure as compared with the one-axis type, but there is no restriction on the open / close angle. The two-axis type has a structure in which opening and closing is performed via two axes, and the entire hinge portion is also rotated at the same time as each axis structure of the two axes rotates. In this two-axis type, since there is a distance between two parallel axes and a margin of opening and closing angle is generated, opening and closing of 360 degrees is also possible.

この360度開閉可能な二軸ヒンジ装置の開閉構造の形態は、種々提案されていて、例えば、カム機構を介して2つの筐体の各々を別に180度で開閉できる構造にして、360度の開閉を可能とする例が知られている(例えば、特許文献1参照)。又、カムとギヤを使用して、2つの筐体の開閉動作を同期させて360度の開閉を行なう構造が知られている(例えば、特許文献2参照)。更に、ギヤとオルダム継ぎ手を使用して、2つの筐体を同期させ360度の開閉動作を可能にしている例も知られている(例えば、特許文献3参照)。   Various forms of the open / close structure of this 360-degree open / close biaxial hinge device have been proposed, for example, a structure capable of opening and closing each of the two casings separately at 180 degrees via a cam mechanism. An example that enables opening and closing is known (see, for example, Patent Document 1). There is also known a structure in which a cam and a gear are used to synchronize opening and closing operations of two housings to perform 360 degree opening and closing (see, for example, Patent Document 2). Furthermore, there is also known an example in which a gear and an Oldham joint are used to synchronize two housings to enable 360-degree opening / closing operation (see, for example, Patent Document 3).

特開2013−249855号公報JP, 2013-249855, A 特開2012−37049号公報JP 2012-37049 A 特開2008−275139号公報JP 2008-275139 A

従来から、これらのヒンジ装置は、比較的小型であるノートパソコン等の電子機器に適用されることで、構造をコンパクトにする努力がなされている。小さくするため、例えば、カム機構やギヤを使用した構造にしているが、小さくするが故に構造は複雑になる傾向があった。前述の特許文献1に記載されたものは、一方はカム構造のみで、2つの筐体を連動させず別々に180度回動させ、2つの筐体で合せて360度の開閉を行なう構造である。   Heretofore, efforts have been made to make the structure compact by being applied to electronic devices such as notebook computers which are relatively small in size. In order to make it smaller, for example, a structure using a cam mechanism or a gear is used, but the structure tends to be complicated because it is made smaller. The one described in the above-mentioned Patent Document 1 has a structure in which one is a cam structure alone, and the two casings are separately rotated 180 degrees without interlocking, and the two casings are combined to perform opening and closing 360 degrees. is there.

このため開閉動作に伴い、他方の筐体の回動を規制する等の構造で複雑になっている。又、前述の特許文献2に記載のものは、ギヤを使用する構造であるが、カム機構も使用している。この構造は、筐体のヒンジ部位に、一方側をカム機構のものにし、他方側をギヤ機構のものに分離させたヒンジ装置になっている。これは、構造が複雑になっているが故であって、しかもそのヒンジ装置の一部は筐体の外部に張り出した構造になっている。   For this reason, along with the opening and closing operation, the structure of restricting the rotation of the other housing is complicated. In addition, although the one described in the aforementioned Patent Document 2 uses a gear, a cam mechanism is also used. This structure is a hinge device in which one side is a cam mechanism and the other side is separated into a gear mechanism at a hinge portion of a housing. This is because of the complexity of the structure, and a part of the hinge device is extended to the outside of the housing.

特許文献3に記載された例は、前者に比しヒンジ装置を比較的簡素にした例のものであるが、オルダム継手を使用している例である。オルダム継手のすべり動作は、常時発生する構成であり、長時間の使用に際しては、磨耗で安定性に欠け確実性を求める点においては、不安を残すおそれのある構造である。構造を簡素化したとはいえ、筐体に対しての取り付けは別に取り付け部材を要する構造でもあり、取り付け部を含めて簡素化したとは言いがたく、前述したように、ヒンジ構造としての安定性、確実性にはなお問題がある。本発明は以上のような技術背景のもとになされたものであり、これら従来の構造の問題点を解決したもので、下記の目的を達成する。   The example described in Patent Document 3 is an example in which the hinge device is relatively simplified as compared to the former, but is an example using an Oldham joint. The sliding motion of the Oldham joint is a configuration that always occurs, and it is a structure that may leave anxiety in terms of lack of stability due to wear and a certainty in long-term use. Although the structure is simplified, the mounting to the housing is also a structure requiring a separate mounting member, and it can not be said that the mounting portion is simplified, and as mentioned above, the stability as the hinge structure Sex and certainty still have problems. The present invention has been made under the technical background as described above, solves the problems of the conventional structure, and achieves the following object.

本発明の目的は、構造が簡素で部品点数が少ない二軸ヒンジ装置を提供することにある。
本発明の他の目的は、動作がスムースで確実性がある二軸ヒンジ装置を提供することにある。
本発明の更に他の目的は、構造が簡素にして低コスト可能な二軸ヒンジ装置を提供することにある。
An object of the present invention is to provide a biaxial hinge device having a simple structure and a small number of parts.
Another object of the present invention is to provide a biaxial hinge device which is smooth and reliable in operation.
Yet another object of the present invention is to provide a low cost biaxial hinge device which is simple in structure.

First Embodiment
FIG. 1 is a front view when a notebook computer 2 to which the biaxial hinge device 1 according to the first embodiment of the present invention is applied is opened. The notebook computer 2 includes, for example, a first case 2a as a display unit and a second case 2b as an operation unit, and the biaxial hinge device 1 has a pair of the two cases 2a and 2b. It is provided by arrangement. The two casings 2a and 2b can be folded via the biaxial hinge device 1 by relative opening and closing operations, and can be opened and closed 360 degrees. The state shown in FIG. 1 is a plan view showing an open state of 180 degrees.

図2は、本発明に関わる二軸ヒンジ装置1の対構成の一方の全体構造を示す外観図である。図3は、その構造を成す分解部品図であり、図2で示す二軸ヒンジ装置1の展開図である。図4は、2つの筐体2a,2bが二軸ヒンジ装置1により開閉される状態を示す部分側面図で、図4(a)は閉じた状態を示し、図4(b)は、180度開いた状態を示し、図4(c)は360度開いた状態を示す。   FIG. 2 is an external view showing an entire structure of one of the pair configuration of the biaxial hinge device 1 according to the present invention. FIG. 3 is an exploded view showing the structure, and is a developed view of the biaxial hinge device 1 shown in FIG. FIG. 4 is a partial side view showing a state in which the two housings 2a and 2b are opened and closed by the biaxial hinge device 1, and FIG. 4 (a) shows a closed state, and FIG. 4 (b) is 180 degrees. The open state is shown, and FIG. 4 (c) shows the state opened 360 degrees.

二軸ヒンジ装置1は、図に示すように2軸の同時回動動作で開閉が可能なヒンジ構成となっていて、2つの筐体2a,2bに跨ってこの2つの筐体2a,2bの左右に、対の状態で取り付けられている。基本的に、この対の構成は、勝手違いはあるがどちらも同一構造なので、一方の側のみの構造、本例においては図1の右側の構造について説明する。   As shown in the figure, the biaxial hinge device 1 has a hinge configuration that can be opened and closed by simultaneous rotational movement of two axes, and the two housings 2a and 2b are straddled across the two housings 2a and 2b. It is attached in the state of the pair on the left and right. Basically, the construction of this pair is selfish, but both are identical, so the construction of only one side, in this example the construction on the right side of FIG. 1, will be described.

第1筐体2aには、第1取付部3aを有して第1ヒンジカム体3がビス等により固定されている。第1取付部3aは、第1ヒンジカム体3と一体構成であり、第1筐体2a側に張り出した構成になっている。第1取付部3aには、ビス等(図示せず)を挿入し、第1筐体2aに取り付けるための貫通孔が設けられている。従って、第1筐体2aとはビス等を介して固定される。図3に示すように、この第1ヒンジカム体3は、中心に貫通孔3bを有し、又、この第1ヒンジカム体3の一方の端部には、円周に沿って歯車状の第1噛合部3cと凸状(軸線方向)の第1カム3dが形成されている。第1噛合部3cは、円周180度以上に亘って歯状の噛合部が成形によって形成されている。   The first hinge cam body 3 is fixed to the first housing 2a by a screw or the like having a first mounting portion 3a. The first mounting portion 3a is integrally formed with the first hinge cam body 3, and is configured to project to the first housing 2a side. The first attachment portion 3a is provided with a through hole for inserting a screw or the like (not shown) and attaching it to the first housing 2a. Therefore, it is fixed to the first housing 2a via a screw or the like. As shown in FIG. 3, the first hinge cam body 3 has a through hole 3b at the center, and one end of the first hinge cam body 3 has a gear-like first along a circumference. A meshing portion 3c and a convex (axial direction) first cam 3d are formed. In the first meshing portion 3c, a tooth-shaped meshing portion is formed by molding over a circumference of 180 degrees or more.

第1カム3dは、第1噛合部3cを外れた範囲の部位に凸状に張り出し単独で形成されている。この第1ヒンジカム体3は、第1取付部3aと、孔3bと、第1噛合部3cと、第1カム3dが一体成形された変形筒状の成形部材である。この成形部材は、例えば、金属を含み強度のあるMIM等の成形品である。他方、第2筐体2b側にも、勝手違いで第2ヒンジカム体4が、第2取付部4aを有して固定されている。この第2ヒンジカム体4も同様に成形品であって中心に孔4bを有し、端部に歯車状の第2噛合部4cと凸状の第2カム4dが形成されている。   The first cam 3d is formed in a projecting manner independently at a portion of the range out of the first meshing portion 3c. The first hinge cam body 3 is a deformed cylindrical shaped member in which the first mounting portion 3a, the hole 3b, the first meshing portion 3c, and the first cam 3d are integrally formed. This molded member is, for example, a molded product such as MIM containing metal and having high strength. On the other hand, the second hinge cam body 4 is also fixed to the second housing 2b side with the second mounting portion 4a. The second hinge cam body 4 is also a molded product and has a hole 4b at the center, and a gear-like second meshing portion 4c and a convex second cam 4d are formed at the end.

第1ヒンジカム体3の孔3bには、第1軸体5が相対回動自在に挿入され、又、この第1軸体5に平行に、第2ヒンジカム体4の孔4bにも、第2軸体6が相対回動自在に挿入されている。この両軸体5,6の端部には、両軸体5,6に跨って連結部材7が連結されている。従って、第1軸体5と第2軸体6は、連結部材7により一体化されている。又、第1ヒンジカム体3と第2ヒンジカム体4の間には、両軸体5,6の軸線に直角方向に、両軸体5,6に跨ってピン8が挿入されている。   The first shaft 5 is relatively rotatably inserted into the hole 3 b of the first hinge cam 3, and the second hinge cam 4 has a second hole 4 b in parallel to the first shaft 5. The shaft 6 is relatively rotatably inserted. A connecting member 7 is connected to the ends of the shafts 5 and 6 across the shafts 5 and 6. Therefore, the first shaft 5 and the second shaft 6 are integrated by the connecting member 7. Further, a pin 8 is inserted between the first hinge cam body 3 and the second hinge cam body 4 in a direction perpendicular to the axes of the both shaft bodies 5 and 6 so as to straddle the both shaft bodies 5 and 6.

このピン8に歯車9が支持され、回動可能に設けられている。本実施の形態では、ピン8で歯車9を回転自在に支承する構成にしているが、ピン8を使用せず歯車9の端部に支持部を設け、この支持部を介し両軸体5,6で支持される構造にしてもよい。この歯車9の両端部には噛合部が形成されていて、一方の第3噛合部9aは第1噛合部3cと噛みあい、他方の第4噛合部9bは第2噛合部4cとが交差して噛みあうようになっている。この噛合部は、回転、又は揺動を伝達するものであれば、ピン歯車状のものであってもよく、又はベベルギヤ状のかみ合い構成のものであってもよい。   A gear 9 is supported by the pin 8 and rotatably provided. In this embodiment, the gear 9 is rotatably supported by the pin 8. However, the pin 8 is not used, and a support is provided at the end of the gear 9, and both shafts 5, 6 may be supported. A meshing portion is formed at both ends of the gear 9. One third meshing portion 9a meshes with the first meshing portion 3c, and the other fourth meshing portion 9b intersects with the second meshing portion 4c. It is supposed to be engaged. The meshing portion may be in the form of a pin gear, as long as it transmits rotation or rocking, or may be in the form of a bevel gear mesh.

即ち、第1噛合部3cと第2噛合部4cとは、歯車9を介して90度向きを変えて連動し同期して回動する構成になっているので、第1噛合部3cが回動すると、歯車9を介して同時に第2噛合部4cが回動する。一方、第1軸体5と第2軸体6に跨って、軸方向移動可能にカムプレート10が設けられている。このカムプレート10には、第1ヒンジカム体3と第2ヒンジカム体4に対向して、各々の位置にカム面10a,10bが形成され、このカム面10a,10bに各々第1カム3d及び第2カム4dが当接している。   That is, since the first meshing portion 3c and the second meshing portion 4c are configured to rotate in synchronization with each other by changing the direction by 90 degrees via the gear 9, the first meshing portion 3c is rotated. Then, the second meshing portion 4 c is simultaneously rotated via the gear 9. On the other hand, a cam plate 10 is provided so as to be movable in the axial direction across the first shaft 5 and the second shaft 6. In the cam plate 10, cam surfaces 10a and 10b are formed at respective positions facing the first hinge cam body 3 and the second hinge cam body 4, and the first cam 3d and the second cam surface 10a are formed on the cam surfaces 10a and 10b, respectively. The two cams 4d are in contact.

カムプレート10と連結部材7との間の各軸体5,6には、コイルスプリングである付勢部材11a,11bが設けられ、この付勢部材11a,11bの付勢力により、カムプレート10は、第1カム3d及び第2カム4d側に常時押圧されている。図においては、この付勢部材11a,11bを、第1軸体5と第2軸体6に各々挿入された構造になっているが、単独の付勢部材を連結部材7に直接保持させ、カムプレート10を付勢させる構造のものであってもよい。   Bias members 11a and 11b, which are coil springs, are provided on the shafts 5 and 6 between the cam plate 10 and the connecting member 7, and the cam plate 10 is fixed by the biasing force of the bias members 11a and 11b. The first cam 3d and the second cam 4d are constantly pressed. Although the biasing members 11a and 11b are respectively inserted into the first shaft 5 and the second shaft 6 in the figure, a single biasing member is directly held by the connecting member 7, The cam plate 10 may be biased.

カム面10a,10bは、第1カム3d及び第2カム4dが当接する際に、筐体の開閉位置を選択的に位置決めするための凹部10cが設けられている。第1カム3d及び第2カム4dが、この凹部10cに嵌りこむと、2つの筐体2a,2bの回動状態を停止(角度位置決め)させることができ、筐体の開閉角度を定位置で保持することができる。例えば、180度の開閉位置を保持させる構造にする場合は、筐体がこの位置に保持できるように、カムプレート10のカム面10a,10bの所定位置に、ノッチ穴状の凹部10cを設けるようにすればよい。   The cam surfaces 10a and 10b are provided with a recess 10c for selectively positioning the open / close position of the housing when the first cam 3d and the second cam 4d abut. When the first cam 3d and the second cam 4d fit into the recess 10c, the rotational states of the two housings 2a and 2b can be stopped (angular positioning), and the opening / closing angle of the housing can be fixed. Can be held. For example, when the open / close position of 180 degrees is to be held, a notch hole-like concave portion 10c is provided at a predetermined position on the cam surfaces 10a and 10b of the cam plate 10 so that the housing can be held at this position. You should do it.

再び開閉操作を行なう場合は、手操作で筐体の開閉を強制的に行なうと、第1カム3d及び第2カム4dが凹部10cから外れ、カムプレート10は、第1カム3d及び第2カム4dの回動動作で、付勢部材11a,11bの付勢力に抗し連結部材7側に戻され移動する。この移動で、第1カム3d及び第2カム4dは、カム面10a,10bのフラット面に乗り上げ、2つの筐体2a,2bの回動が可能となる。   When the opening and closing operation is performed again, when the opening and closing of the housing is forcibly performed manually, the first cam 3d and the second cam 4d are disengaged from the recess 10c, and the cam plate 10 is moved to the first cam 3d and the second cam By the rotation operation of 4 d, it resists the biasing force of the biasing members 11 a and 11 b, returns to the connecting member 7 side, and moves. By this movement, the first cam 3d and the second cam 4d ride on the flat surfaces of the cam surfaces 10a and 10b, and the two housings 2a and 2b can be turned.

二軸ヒンジ装置1は、このような部品点数の少ない簡素な構成になるが、詳細は図示していないが、動作部分をカバー12で覆うことがなされているので、前述した内容の構成は操作者に露見することはない。このような構成になる二軸ヒンジ装置1の開閉操作を行う状態が、図4に示された形態となる。図4(a)は、2つの筐体が閉じられた状態を示す。   Although the biaxial hinge device 1 has a simple configuration with such a small number of parts, the details are not shown, but since the operation part is covered with the cover 12, the configuration of the content described above is an operation. Will not be exposed to A state in which the opening / closing operation of the biaxial hinge device 1 having such a configuration is performed is as shown in FIG. FIG. 4A shows a state in which the two housings are closed.

このとき二軸ヒンジ装置1は、筐体内に内装された状態になるので、外部に露出することはない。図は表示部である第1筐体2aを第2筐体2bに比し薄い形状としている。通常ノートパソコン2を机上において開閉するときは、第2筐体2bを机上に置き、第1筐体2aを持ち上げ開閉する。   At this time, since the biaxial hinge device 1 is in a state of being installed in the housing, it is not exposed to the outside. In the figure, the first case 2a, which is a display unit, is thinner than the second case 2b. Usually, when the notebook computer 2 is opened and closed on a desk, the second housing 2b is placed on the desk, and the first housing 2a is lifted and opened.

図4(b)は、2つの筐体2a,2bが180度開閉した状態を示す。2つの筐体2a,2bは、二軸ヒンジ装置1の第1軸体5と第2軸体6の各々の軸周りに90度回動すると同時に、二軸ヒンジ装置1そのものも公転状態で90度回動し、筐体は180度の開きとなる。2つの筐体2a,2bは、この開閉を相互に干渉なく、スムースに行なえるように角部はR面形状となっている。   FIG. 4B shows a state in which the two housings 2a and 2b are opened and closed 180 degrees. The two housings 2a and 2b rotate 90 degrees around the respective axes of the first shaft 5 and the second shaft 6 of the biaxial hinge device 1, and at the same time, the biaxial hinge device 1 itself is also rotated 90 The case turns 180 degrees open. The corners of the two casings 2a and 2b have an R-shape so that the opening and closing can be performed smoothly without interference with each other.

このR面形状により、図4(b)の二点鎖線の開閉途中の状態で示すように、第1の筐体2aは第2の筐体2bとの間で干渉することなく開閉させることができる。図4(c)は、2つの筐体2a,2bが360度開閉した状態を示す。この状態になると、両筐体は表示部と操作部が両表面に露出した外観となる。本発明の構成は、基本的に以上説明した構成になるが、次に他の実施の形態について説明する。   Due to this R-surface shape, as shown in the middle of the opening and closing of the two-dot chain line in FIG. 4B, the first case 2a can be opened and closed without interference with the second case 2b. it can. FIG. 4C shows a state in which the two housings 2a and 2b are opened and closed 360 degrees. In this state, both housings have an appearance in which the display unit and the operation unit are exposed on both surfaces. The configuration of the present invention is basically the above-described configuration, but next, another embodiment will be described.

[実施の形態2]
図5に示す実施の形態2の構造は、基本構成は前述した図1の右側に示す同様構造のものとほぼ同一であるが、この例は、2つの筐体2a,2bを開閉させる際、相対的に2つの筐体2a,2bの位置をずらすことを可能にした構成である。前述の場合は開閉動作に伴い、2つの筐体2a,2bの角部の干渉を避けるため、角部をR面形状としている。
Second Embodiment
The basic structure of the second embodiment shown in FIG. 5 is substantially the same as that of the similar structure shown on the right side of FIG. 1 described above, but in this example, when opening and closing two housings 2a and 2b, It is possible to shift the positions of the two casings 2a and 2b relatively. In the case described above, in order to avoid the interference of the corner portions of the two casings 2a and 2b with the opening and closing operation, the corner portion has an R-shape.

実施の形態2の構造は、そのR面形状を大きく施さなくても干渉することなく開閉操作を行なえるようにしたものである。図6は、図5で示す構成において、本実施の形態2に関わる部分のみ部品分解で示した展開図である。本構造は、2つの筐体2a,2bの一方の第2筐体2b側の取付部の構造を、変形させたものである。第2ヒンジカム体4の第2筐体2b側をステー状に張り出し、前述した取付部4aの構成を、スライド部13への取付構造に変形したものである。   The structure of the second embodiment is such that the opening and closing operation can be performed without interference even if the R-shaped surface is not largely formed. FIG. 6 is a developed view in which only the part related to the second embodiment is shown in a disassembled state in the configuration shown in FIG. This structure is a modification of the structure of the attachment portion on the side of the second housing 2b on one of the two housings 2a and 2b. The second housing 2b side of the second hinge cam body 4 is extended in a stay shape, and the configuration of the mounting portion 4a described above is modified into a mounting structure to the slide portion 13.

このスライド部13は、2つの長溝13a,13bを有している。一方、第2筐体2bに対しては、第2ヒンジカム体4とは分離して単独に第2の取付部である取付プレート14を固定する。この取付プレート14には、この取付プレート14を第2筐体2bへ取り付けるための貫通孔14aと、スライド部13をこの取付プレート14に重ね合わせの状態で、固定ピン15を取り付けるための貫通孔14bが設けられている。固定ピン15は、貫通孔14bに貫通後、先端をかしめにより固定される。   The slide portion 13 has two long grooves 13a and 13b. On the other hand, with respect to the second housing 2b, the mounting plate 14 which is a second mounting portion is fixed separately from the second hinge cam body 4. The mounting plate 14 has a through hole 14a for mounting the mounting plate 14 to the second housing 2b and a through hole for mounting the fixing pin 15 in a state where the slide portion 13 is superimposed on the mounting plate 14 14b is provided. The fixing pin 15 is fixed by caulking the tip after passing through the through hole 14 b.

この取り付けは、スライド部13の長溝13a,13bを介し固定ピン15によっていて、プレート16を挟んで、スライド部13と取付プレート14とは、第2軸体6の軸線に対し直角方向に相対的に移動可能に取り付けられるようになっている。この固定ピン15は、首下に段差部15aを有してプレート16に当接し、スライド部13の長溝13a,13bに対しての部位は、ピン形状部15bを有している。   This mounting is performed by the fixing pin 15 through the long grooves 13a and 13b of the slide portion 13, and the plate 16 is sandwiched, and the slide portion 13 and the mounting plate 14 are relative to each other in the direction perpendicular to the axis of the second shaft 6. It is movably attached to the The fixing pin 15 has a step portion 15a below the neck and abuts on the plate 16, and a portion with respect to the long grooves 13a and 13b of the slide portion 13 has a pin-shaped portion 15b.

スライド部13の取り付けの孔は、長楕円状の長溝13a,13bになっているので、取付プレート14との間では長溝13a,13bに沿って、ピン形状部15bによって案内され取り付け位置の移動が可能である。この移動のためには、所定の隙間が必要となる。しかし、この隙間のためスライド部13と取付プレート14との間にガタが生じると支障が出るので、このガタを除くため、固定ピン15の首下の段差部15aとプレート16との間に、重ね合せ方向に付勢する付勢部材21を設けた。   Since the mounting holes of the slide portion 13 are long oval shaped long grooves 13a and 13b, they are guided by the pin shape portion 15b along the long grooves 13a and 13b between the mounting plate 14 and the mounting position moves It is possible. For this movement, a predetermined gap is required. However, if a backlash occurs between the slide portion 13 and the mounting plate 14 due to this gap, a hindrance occurs. Therefore, between the step portion 15a below the neck of the fixing pin 15 and the plate 16 in order to remove the backlash. A biasing member 21 is provided which biases in the stacking direction.

この付勢部材21は、中央に弾性変形する凹部を有する板状のもので、2つの貫通孔を有し、挟み重ね合わせ方向に凹部で弾性押圧する板バネである。この板バネの付勢力でスライド部13を取付プレート14に押圧しガタを除いている。しかし、この付勢部材21は、板バネに限定されず、皿バネであってもよく、付勢機能を有するものであればどのようなものでもよい。   The biasing member 21 is a plate-like member having a recess that is elastically deformed at the center, and is a plate spring having two through holes and elastically pressing the recess in the sandwiching direction. The slide portion 13 is pressed against the mounting plate 14 by the biasing force of the plate spring to remove backlash. However, the biasing member 21 is not limited to a plate spring, and may be a disc spring, and any member having a biasing function may be used.

一方の長溝13aには、付勢部材17が設けられていて、取付プレート14に固定されている固定ピン15を付勢し、取付プレート14を第2軸体6側に押圧している。即ち、第2ヒンジカム体4と第2筐体2b側とは近寄る方向に押圧されて、2つの筐体2a,2bの姿勢を維持している。   A biasing member 17 is provided in one of the long grooves 13a, and biases the fixing pin 15 fixed to the mounting plate 14 to press the mounting plate 14 toward the second shaft 6 side. That is, the second hinge cam body 4 and the second housing 2b are pressed in the direction to approach each other, and the postures of the two housings 2a and 2b are maintained.

この取付プレート14には、折り曲げ構造によるプレートカム部14cが一体で設けられていて、第2軸体6に固定されたカム部材18とこのプレートカム部14cのカム面が当接するようになっている。即ち、開閉動作に伴い、第2ヒンジカム体4が第2軸体6と相対的に回動すると、カム部材18の中心位置Sに対するプレートカム部14cの当接位置が付勢部材17の付勢力に抗して相対的にずれる。このずれが第2ヒンジカム体4と取付プレート14の位置ずれとなり、結果的に二軸ヒンジ装置1は、第2筐体2bから離れる方向に位置が相対的に変わることになる。   A plate cam portion 14c having a bending structure is integrally provided on the mounting plate 14, and the cam surface of the plate cam portion 14c abuts on the cam member 18 fixed to the second shaft 6 There is. That is, when the second hinge cam body 4 rotates relative to the second shaft body 6 with the opening and closing operation, the contact position of the plate cam portion 14c with respect to the central position S of the cam member 18 is the biasing force of the biasing member 17 Relatively offset against This displacement results in displacement between the second hinge cam body 4 and the mounting plate 14, and as a result, the biaxial hinge device 1 relatively changes its position in the direction away from the second housing 2b.

このずれは、カム部材18のカム形状によって定められる。このカム形状は2つの筐体2a,2bが角部を大きくR面形状に施さなくても、干渉しない位置を維持しながら、開閉動作を行なうことができる離間寸法の得られる形状とする。例えば、カム部材18のカム形状を図7に示す形状にすると、開閉回動に伴い、図の二点鎖線位置Hに示すように、プレートカム部14cはカム部材18の中心位置Sに対し、相対的に位置がずれる。   This deviation is determined by the cam shape of the cam member 18. This cam shape is a shape capable of obtaining a separation dimension capable of performing the opening / closing operation while maintaining a position not interfering even if the two housings 2a and 2b do not have the corner portions in a large R-face shape. For example, when the cam shape of the cam member 18 is made the shape shown in FIG. 7, the plate cam portion 14 c is located relative to the central position S of the cam member 18 as shown by the two-dot chain line position H in FIG. Relatively misaligned.

このような構成において、この位置ずれの各動作部の動きをよくするためグリース等の潤滑剤を塗布している。本例では、スライド13a,13bの固定ピン15のピン形状部15bまわり、スライド部13と取付プレート14との間、カム部材18とプレートカム部14cの当接部である。しかしこの各動作部の動きをよくするため、グリースを要しない潤滑性のある部材構成にしてもよい。   In such a configuration, a lubricant such as grease is applied in order to improve the movement of the respective operation units of this positional deviation. In this example, around the pin-shaped portion 15b of the fixing pin 15 of the slides 13a and 13b, between the slide portion 13 and the mounting plate 14, a contact portion between the cam member 18 and the plate cam portion 14c. However, in order to improve the movement of the respective operation parts, it is possible to use a member configuration having lubricity which does not require grease.

この開閉に伴う筐体の開閉軌跡は、図8に示す形態となる。図8は、カム部材18の中心Sを基点にしてのずれを示すための模式的な説明図としている。図8のX位置の軌跡が、本実施の形態2の構造を有しない、前述した実施の形態1の場合の開閉軌跡である。これに対し、Y位置の軌跡が、本実施の形態2における筐体の開閉軌跡となる。X,Yは2つの筐体2a,2b間の位置構成を示しているが、Zはその寸法差を示し、本発明構成によって生ずるずれである。   The opening and closing locus of the case accompanying this opening and closing becomes a form shown in FIG. FIG. 8 is a schematic explanatory view for showing the deviation of the cam member 18 based on the center S of the cam member 18. The locus of the X position in FIG. 8 is the open / close locus in the case of the first embodiment described above which does not have the structure of the second embodiment. On the other hand, the locus of the Y position is the opening and closing locus of the housing in the second embodiment. Although X and Y show the positional configuration between the two housings 2a and 2b, Z indicates the difference in size, which is a displacement caused by the configuration of the present invention.

図8で示すように、第1筐体2aは第2筐体2bに対し、開閉動作に伴い相互の筐体が離間しながら開閉を行なうことができる。このため筐体の角部を大きくR面形状にする必要がない筐体構成が実現できる。この構成を示したのが図9で、R面形状の小さい構成の2つの筐体2a,2bが閉じたときの部分側面図である。大きくR面形状にしない構成の筐体はデザイン性の効果が大きく、この筐体を閉じたときは、箱状形態のすっきりしたデザイン構成の筐体構成が可能となる。以上本実施の形態2を第2筐体2bに設けることで説明したが、第1筐体2aに適用してもよいことはいうまでもない。   As shown in FIG. 8, the first housing 2a can be opened and closed with respect to the second housing 2b while the mutual housings are separated with each other in accordance with the opening and closing operation. Therefore, it is possible to realize a housing configuration that does not require the corner portions of the housing to be largely rounded. This configuration is shown in FIG. 9, which is a partial side view when the two casings 2a and 2b having a configuration with a small R-shape are closed. The casing having a configuration that does not have a large R-surface shape has a large design effect, and when the casing is closed, a casing configuration with a neat box-like configuration can be achieved. Although the second embodiment has been described above in the second case 2b, it is needless to say that the second embodiment may be applied to the first case 2a.

[実施の形態3]
次に、図10、11をもとに、本発明の実施の形態3の二軸ヒンジ装置を説明する。実施の形態3の二軸ヒンジ装置は、開閉動作に伴う開閉角度位置を検知するための検知装置を有するものである。本実施の形態3のものは、2つの筐体2a,2bが閉じたことを検知するための構成である。本構造を第1筐体2aに適用したときの例で説明する。図10に示すように、第1軸体5の端部に接触子19が固定されている。この接触子19は、取り付け部がフラット構成で、端部が検知子19aとなっている。
Third Embodiment
Next, a biaxial hinge device according to a third embodiment of the present invention will be described based on FIGS. The biaxial hinge apparatus according to the third embodiment has a detection device for detecting an open / close angular position involved in the open / close operation. The third embodiment is a configuration for detecting that the two housings 2a and 2b are closed. An example in which the present structure is applied to the first housing 2a will be described. As shown in FIG. 10, the contact 19 is fixed to the end of the first shaft 5. The contact 19 has a flat attachment portion and an end is a detector 19a.

この検知子19aの位置を検知する検知手段20が、第1筐体2aに設けられている。この検知手段20は、図11に模式的に示すように、第2筐体2b内部の壁面に固定されている。図11(a)に示すように、開閉時に二軸ヒンジ装置1は、第1筐体2aが第2筐体2bと相対動作を行ない閉じたとき、検知子19aが検知手段20に接触し導電状態となり、閉じたことを検知している。このように本実施の形態3の検知装置においては、2つの筐体2a,2bが閉じたときに接触して閉じたことを検知している。   Detection means 20 for detecting the position of the detection element 19a is provided in the first housing 2a. This detection means 20 is being fixed to the wall surface inside 2nd housing | casing 2b, as typically shown in FIG. As shown in FIG. 11 (a), when the first housing 2a performs a relative operation with the second housing 2b and closes, the detector 19a contacts the detection means 20 and becomes conductive. It becomes a state and detects that it closed. As described above, in the detection device of the third embodiment, when the two housings 2a and 2b are closed, it is detected that they are in contact and closed.

この検知により例えば、ノートパソコンが閉じたときは、使用していない状態であるので、閉じたことを検知しノートパソコンの電源を自動的に遮断する等のことを行なうことができる。又、360度回動させた状態を検知する設定にすると、表示部が露出し、タブレット端末として利用が可能となり、そのため操作部の機能を停止させる検知手段とすることも可能である。このように、検知子19aが検知手段20に対して相対位置の設定ができるので、この位置関係を検知したい2つの筐体の開閉角度を任意に設定することができる。   By this detection, for example, when the notebook computer is closed, since it is not in use, it is possible to detect the closing and automatically shut off the notebook computer. In addition, when setting is made to detect a state rotated 360 degrees, the display unit is exposed and can be used as a tablet terminal. Therefore, it is possible to use a detection unit that stops the function of the operation unit. As described above, since the detector 19a can set the relative position with respect to the detector 20, it is possible to arbitrarily set the open / close angle of the two casings whose position relationship is to be detected.

図11(b)に示すように、開くときは接触状態にならないので、非導電状態となり自動的に遮断解除の状態となる。このように本実施の形態3のものは、ノートパソコン使用時に仮に電源を遮断せず閉じたとしても、自動的に電源遮断が実現できるので、節電効果を高めるのにも寄与し効果がある。   As shown in FIG. 11 (b), since the contact state does not occur when the cover is opened, it is in the non-conductive state and is automatically in the blocking release state. As described above, according to the third embodiment, even if the power is not shut off temporarily when the notebook computer is used, the power shutoff can be realized automatically. Therefore, the power saving effect can be enhanced.
