この発明は、一対の筐体を互いに回動可能に連結する二軸ヒンジ装置に関する。   The present invention relates to a biaxial hinge device that couples a pair of casings so as to be rotatable relative to each other.

一対の筐体が互いに折畳まれる折畳状態と、互いに開いて展開された展開状態とに切換可能なように、該一対の筐体を互いに回動可能に連結するヒンジ装置が従来公知であるが、このようなヒンジ装置において、一方の筐体と一体的に回動する第1回動部材の回動軸と、他方の筐体と一体的に回動する第2回動部材の回動軸とを、同一軸心として単一の回動軸により構成した場合、一対の筐体を互いに厚み方向に重ね合せて上記折畳状態への切換を可能にするために、この単一の回動軸を、一方の筐体に対して、厚み方向にずらした位置に配設(厚み方向にオフセット)する必要がある。   2. Description of the Related Art Conventionally, a hinge device that couples a pair of casings so as to be pivotable so that the paired casings can be switched between a folded state in which the pair of casings are folded with each other and an unfolded state in which the pair of casings are opened and unfolded. However, in such a hinge device, the rotation shaft of the first rotation member that rotates integrally with one housing and the rotation of the second rotation member that rotates integrally with the other housing. When the moving shaft is configured by a single rotating shaft as the same axis, the single casing is overlapped in the thickness direction to enable switching to the folded state. It is necessary to dispose the rotation shaft at a position shifted in the thickness direction (offset in the thickness direction) with respect to one housing.

例えば、図11(A)に示す例では、第1筐体Aと第2筐体Bとを互いに回動可能に連結するヒンジ装置51における単一の回動軸52が、第1筐体Aに対して厚み方向にオフセットされており、この配置構成によって折畳状態への切換を可能にしている。
ただし、このようなヒンジ装置51では、展開状態に切換えた際、第1筐体Aと第2筐体Bが互いに厚み方向にずれた状態になり、段差が形成され、一対の筐体A,Bによって単一のフラットな面を形成することができないという問題があった。
For example, in the example shown in FIG. 11A, the single rotation shaft 52 in the hinge device 51 that connects the first housing A and the second housing B so as to be rotatable is the first housing A. Is offset in the thickness direction, and this arrangement makes it possible to switch to the folded state.
However, in such a hinge device 51, when switched to the unfolded state, the first casing A and the second casing B are shifted from each other in the thickness direction, a step is formed, and the pair of casings A, There was a problem that a single flat surface could not be formed by B.

このため、図11(B)に示すように、第1筐体Aの回動軸54Aと、第2筐体Bの回動軸54Bとを2列に並べて形成し、展開状態時に、一対の筐体A,Bの表裏面によって単一のフラットな面を形成可能とした二軸ヒンジ装置53が開発され、公知になっていた。   For this reason, as shown in FIG. 11 (B), the rotation shaft 54A of the first housing A and the rotation shaft 54B of the second housing B are formed in two rows, and in a deployed state, A biaxial hinge device 53 capable of forming a single flat surface by the front and back surfaces of the housings A and B has been developed and is publicly known.

さらに、これを改良したものとして、一方の筐体と一体的に回動する第1回動部材の回動軸と、他方の筐体と一体的に回動する第2回動部材の回動軸とを2列に並べて形成するとともに、第1回動部材と第2回動部材を回動可能に軸支して連結するベース部材と、第1回動部材の回動に伴って第2回動部材を反対方向に回動させる連動機構とを設け、折畳状態から展開状態への切換又は展開状態から折畳状態への切換をスムーズに行うことが可能な特許文献1に示す二軸ヒンジ装置が開発され、公知になっている。   Furthermore, as an improvement of this, the rotation shaft of the first rotation member that rotates integrally with one housing and the rotation of the second rotation member that rotates integrally with the other housing. A shaft is formed in two rows, a base member that pivotally supports and connects the first rotating member and the second rotating member, and a second member as the first rotating member rotates. The biaxial shown in Patent Document 1 is provided with an interlocking mechanism that rotates the rotating member in the opposite direction, and can smoothly switch from the folded state to the unfolded state or from the unfolded state to the folded state. Hinge devices have been developed and are known.

When determining the position of each rotating shaft in the long hole, each operation guide portion is set so that the distance between the rotating shafts during the folding and unfolding rotation is larger than that in the folded state and the unfolding state. If a connecting means allowing the change in the connecting distance between the pair of connecting arms is provided on the connecting rod side, the movement trajectory of the operating pin is changed by selecting the shape of the operating guide, and the rotating member is rotated. According to the moving position, it becomes easy to set in detail the separation / proximity operation of the rotating shaft, which is highly convenient.

さらに、各連結アームの先端側をガイド可能に係合させる作動ガイド部を有するガイド部材を設け、回動位置に応じた連結アーム先端側の作動ガイド部での位置の設定によって、連結アームの回動位置に対する各回動軸の長孔での位置を定めるにあたって、折畳状態時及び展開状態時よりも折畳・展開回動中の回動軸間距離が大きくなるように設定し、各作動ガイド部を形成し、一対の連結アーム間の連結距離の変化を許容する融通手段を連結ロッド側に設けものによれば、作動ガイド部の形状選択によって、作動ピンの移動軌跡を変更し、回動部材の回動位置に応じて、回動軸の離間・近接作動を詳細に設定することが容易になり、利便性が高い他、ベース部材と別体であるガイド部材に作動ガイド部が形成されるため、作動ガイド部材の形状選択のバリエーションがより広がる。   Furthermore, a guide member having an operation guide portion that engages the distal end side of each connection arm so as to be able to guide is provided, and the rotation of the connection arm is determined by setting the position of the operation guide portion on the connection arm distal end side according to the rotation position. When determining the position of each rotating shaft in the long hole relative to the moving position, set the distance between the rotating shafts during folding and unfolding rotation to be greater than in the folded state and unfolded state, and each operation guide According to the present invention, there is provided an interchangeable means on the connecting rod side that allows a change in the connecting distance between the pair of connecting arms, so that the moving locus of the operating pin can be changed and rotated by selecting the shape of the operating guide. According to the rotation position of the member, it becomes easy to set the details of the separation / proximity operation of the rotation shaft, which is highly convenient and the operation guide portion is formed on the guide member that is separate from the base member. For the operation guide member Variations of Jo selection is spread more.

また、ガイド部材におけるベース部材の反対側に連結ロッドを配置し、連結ロッドと連結アームとを連結する連結ピンを挿通させるガイド孔からなる作動ガイド部を、ガイド部材に穿設したものによれば、作動ガイド部に係合させる部分を、連結アームに別途形成する必要がなく、部品点数が減少する。   Further, according to the guide member, the connecting rod is disposed on the opposite side of the base member, and the guide member is provided with an operation guide portion including a guide hole through which a connecting pin for connecting the connecting rod and the connecting arm is inserted. The part engaged with the operation guide part does not need to be separately formed in the connecting arm, and the number of parts is reduced.

なお、連結アーム側の連結ピンをスライド可能に挿入されるスライド部を連結ロッドに形成し、該スライド部によって前記融通手段を構成すれば、前記融通手段をより簡易な構造で実現できるため、コスト的メリットが大きい。   In addition, if the slide part into which the connecting pin on the side of the connecting arm is slidably inserted is formed in the connecting rod and the accommodation means is constituted by the slide part, the accommodation means can be realized with a simpler structure. Significant merit.

続いて、支持ピン2A,2Bの連結アーム16A,16Bから突出した挿通部9b、9bにスペーサ21,21を外装した後、支持ピン2A,2Bの先端側取付部9a,9aを回動部材3A,3Bに挿入して取付固定し、二軸ヒンジ装置1の組立を完了する。   Subsequently, after the spacers 21 and 21 are sheathed on the insertion portions 9b and 9b protruding from the connecting arms 16A and 16B of the support pins 2A and 2B, the distal end side attachment portions 9a and 9a of the support pins 2A and 2B are turned to the rotating member 3A. , 3B to be attached and fixed, and the assembly of the biaxial hinge device 1 is completed.

次に、図4乃至図7に基づき、二軸ヒンジ装置1の作動について説明する。
図4は、折畳状態に切換えられた二軸ヒンジ装置の要部斜視図であり、図5は、折畳状態から展開状態に切換える途中の二軸ヒンジ装置の要部斜視図であり、図6は、展開状態に切換えられた二軸ヒンジ装置の要部斜視図であり、図7(A)は折畳状態に切換えられた二軸ヒンジ装置の要部側面図であり、(B)は折畳状態から展開状態に切換えられる途中の二軸ヒンジ装置の要部側面図であり、(C)は展開状態に切換えられた二軸ヒンジ装置の要部側面図である。
Next, the operation of the biaxial hinge device 1 will be described with reference to FIGS.
4 is a perspective view of the main part of the biaxial hinge device switched to the folded state, and FIG. 5 is a perspective view of the main part of the biaxial hinge device being switched from the folded state to the expanded state. 6 is a perspective view of the main part of the biaxial hinge device switched to the unfolded state, FIG. 7A is a side view of the main part of the biaxial hinge device switched to the folded state, and FIG. It is a principal part side view of the biaxial hinge apparatus in the middle of being switched from a folding state to an expansion | deployment state, (C) is a principal part side view of the biaxial hinge apparatus switched to the expansion | deployment state.

ちなみに、図7では、回動軸2A,2B間の距離(軸間距離)をD、連結アーム16A,16Bの回動支点から連結ピン20までの距離(アーム全長)をR、連結ロッド17の両側連結孔17b、17b間の距離(ロッド全長)をLとして示している。   Incidentally, in FIG. 7, the distance between the rotation shafts 2A and 2B (distance between the axes) is D, the distance from the rotation fulcrum of the connection arms 16A and 16B to the connection pin 20 (the total arm length) is R, and the connection rod 17 The distance between the two side coupling holes 17b, 17b (full length of the rod) is indicated as L.

二軸ヒンジ装置1は、一対の筐体A,Bの折畳状態時には、一対の回動軸2A,2Bを最短で結ぶ仮想線に対して、各連結アーム16A,16Bが45度傾いた状態になり、この折畳状態から一方の回動軸2Aを他方の回動軸2Bから離間するように、所定角度αだけ回動させると、リンク機構5の作用により、該他方の回動軸2Bも該一方の回動軸2Aから離間するように、所定角度αだけ回動される。   In the biaxial hinge device 1, when the pair of housings A and B are folded, the connecting arms 16A and 16B are inclined 45 degrees with respect to the imaginary line that connects the pair of rotating shafts 2A and 2B in the shortest distance. In this folded state, when the one rotation shaft 2A is rotated by a predetermined angle α so as to be separated from the other rotation shaft 2B, the other rotation shaft 2B is operated by the link mechanism 5. Is also rotated by a predetermined angle α so as to be separated from the one rotation shaft 2A.

すなわち、一対の筐体A,Bにおける互いの回動角(開き角)をθとすると、開き角θが0度の場合が折畳状態になり、開き角θが180度の場合が展開状態になり、連結アーム16A,16Bの折畳状態からの回動角であるアーム回動角αと、上記開き角θとの間には、以下の式が成立する。   That is, when the rotation angle (opening angle) of the pair of casings A and B is θ, the opening state θ is 0 degree when the opening angle θ is 180 degrees, and the opening angle θ is 180 degrees when the opening state is 180 degrees. Thus, the following equation is established between the arm rotation angle α, which is the rotation angle from the folded state of the connecting arms 16A, 16B, and the opening angle θ.

Figure 0006121683
Figure 0006121683

そして、軸間距離Dは、アーム全長Rと、ロッド全長Lと、開き角θを用い、次の式が表される。   The inter-axis distance D is expressed by the following equation using the arm total length R, the rod total length L, and the opening angle θ.

Figure 0006121683
Figure 0006121683

ちなみに、「−45度」の値は、連結アーム16A,16Bの回動部材3A,3Bに対する相対的な角度を変えることにより、変更可能である。そして、アーム回動角αが60度の時に、軸間距離Dを最大としたければ、この値を「−60度」に設定する必要があり、−90度〜0度の範囲で変更できる。   Incidentally, the value of “−45 degrees” can be changed by changing the relative angles of the connecting arms 16A and 16B with respect to the rotating members 3A and 3B. If the inter-axis distance D is to be maximized when the arm rotation angle α is 60 degrees, this value needs to be set to “−60 degrees” and can be changed in the range of −90 degrees to 0 degrees. .

以上により、図示する例では、開き角θが0度の折畳状態時に軸間距離Dが最小になり(図4,図7(A)参照)、開き角θを0度から90度の間で増加させると、軸間距離Dが増加し、開き角θが90度になった時点で、軸間距離Dが最大になり(図5,図7(B)参照)、開き角θを90度から180度の間で増加させると、軸間距離Dが減少し、開き角θが180度になった展開状態に切換えられ、軸間距離Dが再び最小になる(図6,図7(C)参照)。   As described above, in the illustrated example, the distance D between the axes is minimized when the opening angle θ is 0 degrees (see FIGS. 4 and 7A), and the opening angle θ is between 0 degrees and 90 degrees. Is increased, the inter-axis distance D increases, and when the opening angle θ reaches 90 degrees, the inter-axis distance D becomes maximum (see FIGS. 5 and 7B), and the opening angle θ is set to 90. When the angle is increased from 180 degrees to 180 degrees, the inter-axis distance D decreases and the opening angle θ is switched to 180 degrees, and the inter-axis distance D is minimized again (FIGS. 6 and 7). C)).

すなわち、リンク機構5は、第1回動アーム3Aの回動に伴って第2回動アーム3Bを反対方向に回動させる連動機構として機能するとともに、折畳状態時及び展開状態時によりも折畳・展開回動中の軸間距離D(回動軸2A,2B間距離)が大きくなるように該軸間距離Dを回動軸2A,2Bの回動に伴って変動させる変動機構としても機能しており、このように、単一のリンク機構5に、連動機構と変動機構の2つの機能を一体的に持たせることにより、構成を簡略化し、コストを低減させている。   That is, the link mechanism 5 functions as an interlocking mechanism that rotates the second rotating arm 3B in the opposite direction with the rotation of the first rotating arm 3A, and can be folded even in the folded state and the expanded state. As a variable mechanism that varies the inter-axis distance D with the rotation of the rotation shafts 2A and 2B so that the inter-axis distance D (distance between the rotation shafts 2A and 2B) during tatami mat deployment and rotation is increased. Thus, the single link mechanism 5 is integrally provided with the two functions of the interlocking mechanism and the variable mechanism, thereby simplifying the configuration and reducing the cost.

なお、上述したように、開き角θが0度になる折畳状態時や、開き角θが180度になる展開状態時に、凸部24と凹部26とが凹凸嵌合されて係止されるが、凸部24が凹部26に完全に嵌り込んだ状態では、ガタが発生する場合がある。そこで、凸部24と凹部26が完全に嵌合する手前の状態で、一対の筐体A,Bが折畳状態や展開状態に切換えられるように、凸部24及び凹部26の位相をずらして配置構成してもよい。   Note that, as described above, the convex portion 24 and the concave portion 26 are engaged with and engaged with each other in a folded state where the opening angle θ is 0 degrees or in a deployed state where the opening angle θ is 180 degrees. However, in a state where the convex portion 24 is completely fitted in the concave portion 26, rattling may occur. Therefore, the phases of the convex portion 24 and the concave portion 26 are shifted so that the pair of housings A and B can be switched to the folded state or the unfolded state in a state before the convex portion 24 and the concave portion 26 are completely fitted. You may arrange.

具体的には、開き角θがマイナス角(図示する例では−6度程度)の状態で、凸部24と凹部26が完全に嵌合するとともに、開き角θが180度よりも大きい角度(図示する例では186度程度)の状態で、凸部24と凹部26とが完全に嵌合するように凸部24及び凹部26を配置する一方で、一対の筐体A,Bに対しては、開き角度θが0度よりも小さい角度及び180度よりも大きい角度にならないように、各筐体A,Bの回動を規制する規制手段を設け、これによって、折畳状態時及び展開状態時におけるガタが防止する。   Specifically, in a state where the opening angle θ is a minus angle (about −6 degrees in the illustrated example), the convex portion 24 and the concave portion 26 are completely fitted, and the opening angle θ is larger than 180 degrees ( In the illustrated example, the convex portion 24 and the concave portion 26 are arranged so that the convex portion 24 and the concave portion 26 are completely fitted to each other, while the pair of housings A and B are In addition, there are provided restricting means for restricting the rotation of the respective casings A and B so that the opening angle θ is not smaller than 0 degrees and larger than 180 degrees, so that the folded state and the unfolded state are provided. Prevent backlash at the time.

ちなみに、開き角度θが0度の場合には、筐体A,B同士が接触又は略接触状態で対向するため、各別に規制手段を設けなくてもよく、開き角θが180度より大きくならないように筐体A,B同の回動を規制するストッパ等の規制手段を設ければよい。   Incidentally, when the opening angle θ is 0 degree, the casings A and B face each other in contact or substantially in contact with each other, so that it is not necessary to provide a regulating means separately, and the opening angle θ does not become larger than 180 degrees. Thus, a restricting means such as a stopper for restricting the rotation of the casings A and B may be provided.

次に、図8乃至図10に基づき二軸ヒンジ装置の別実施形態について上述した例と異なる点を説明する。
図8は、二軸ヒンジ装置の別実施形態を示す要部分解斜視図であり、図9は、図8に示すベースプレートの片面側の構成を示す側面図である。図示する二軸ヒンジ装置1では、回動軸2A,2Bと一体回動する連結アーム16A,16Bの先端部には、ベースプレート4側に突出する作動ピン29と、ベースプレート4の反対側に突出する前記連結ピン20とがそれぞれ一体形成されている。一方、ベースプレート1には、一対の作動ピン29が個別に挿入される一対の作動ガイド孔(作動ガイド部)31A,31Bがそれぞれ穿設されている。
Next, a different point from the example mentioned above about another embodiment of a biaxial hinge device based on Drawing 8 thru / or Drawing 10 is explained.
FIG. 8 is an exploded perspective view of a main part showing another embodiment of the biaxial hinge device, and FIG. 9 is a side view showing a configuration of one side of the base plate shown in FIG. In the biaxial hinge device 1 shown in the figure, at the end of the connecting arms 16A and 16B that rotate together with the rotating shafts 2A and 2B, an operating pin 29 that protrudes toward the base plate 4 and the opposite side of the base plate 4 protrude. The connecting pins 20 are integrally formed. On the other hand, the base plate 1 has a pair of operation guide holes (operation guide portions) 31A and 31B into which the pair of operation pins 29 are individually inserted.

一対の作動ガイド孔31A,31Bは、長孔12A,12B同士の近接側端部から、該長孔12A,12Bに対して交差する方向両側に延設され、第1回動軸2A側の長孔12Aと作動ガイド孔31Aとが一体的に連接されてT字状をなすとともに、第2回動軸2B側の長孔12Bと作動ガイド孔31Bとが一体的に連接されてT字状をなしている。そして、一対の作動ガイド孔31A,31Bは、長手方向両端側に近づく程互いが徐々に近づく円弧状に湾曲しており、この一対の作動ガイド孔31A,31Bの間に、前記ガイド孔11が配置されている。   The pair of operation guide holes 31A, 31B are extended from the adjacent end portions of the long holes 12A, 12B to both sides in the direction intersecting the long holes 12A, 12B, and are long on the first rotating shaft 2A side. The hole 12A and the operation guide hole 31A are integrally connected to form a T shape, and the long hole 12B on the second rotating shaft 2B side and the operation guide hole 31B are integrally connected to form a T shape. There is no. The pair of operation guide holes 31A and 31B are curved in an arc shape that gradually approaches each other as they approach the both ends in the longitudinal direction, and the guide hole 11 is interposed between the pair of operation guide holes 31A and 31B. Has been placed.

そして、第1連結アーム16Aが装着された第1回動軸12Aが長孔12Aに挿入され、該連結アーム16Aの作動ピン29が該長孔12A側の作動ガイド孔31Aに挿入された場合、作動ガイド孔31A内を移動作動する作動ピン29の位置によって、第1回動軸2Aの回動位置及び該回動軸2Aの長孔12A内での位置が一義的に定まる。   When the first rotating shaft 12A to which the first connecting arm 16A is attached is inserted into the long hole 12A, and the operating pin 29 of the connecting arm 16A is inserted into the operating guide hole 31A on the long hole 12A side, The position of the first rotation shaft 2A and the position of the rotation shaft 2A in the long hole 12A are uniquely determined by the position of the operation pin 29 that moves and operates in the operation guide hole 31A.

また、第2連結アーム16Bが装着された第2回動軸12Bが長孔12Bに挿入され、該連結アーム16Bの作動ピン29が該長孔12B側の作動ガイド孔31Bに挿入された場合、作動ガイド孔31B内を移動作動する作動ピン29の位置によって、第2回動軸2Bの回動位置及び該回動軸2Bの長孔12B内での位置が一義的に定まる。   Further, when the second rotating shaft 12B to which the second connection arm 16B is attached is inserted into the long hole 12B, and the operation pin 29 of the connection arm 16B is inserted into the operation guide hole 31B on the long hole 12B side, The position of the second rotation shaft 2B and the position of the rotation shaft 2B in the long hole 12B are uniquely determined by the position of the operation pin 29 that moves and operates in the operation guide hole 31B.

このような構成によれば、一対の回動軸2A,2Bの回動中、連結ピン20,20同士の距離が一定ではなく、変化する。このため、連結ロッド17には、上述した連結孔17b,17bに代えて、挿入時における連結ピン20,20の連結ロッド17長手方向のスライド移動を許容する長孔状のスライド孔(スライド部,融通手段)17c、17cが該連結ロッド17に形成されている。   According to such a configuration, the distance between the connecting pins 20 and 20 is not constant and changes during the rotation of the pair of rotating shafts 2A and 2B. For this reason, instead of the above-described connecting holes 17b and 17b, the connecting rod 17 has a long hole-like slide hole (sliding part, 20) that allows the connecting pins 20 and 20 to slide in the longitudinal direction of the connecting rod 17 during insertion. (Measuring means) 17 c and 17 c are formed on the connecting rod 17.

一対の連結アーム16A,16Bの連結ピン20,20を、連結ロッド17の一対のスライド孔17c,17cに挿入することにより、連結アーム16A,16B同士のアーム回動角αが常に同一になるように、一対の回動アーム3A,3Bが回動作動される。また、各連結アーム16A,16Bの取付孔19周縁には、前記スペーサ21が一体形成により設けられている。   By inserting the connecting pins 20 and 20 of the pair of connecting arms 16A and 16B into the pair of slide holes 17c and 17c of the connecting rod 17, the arm rotation angles α between the connecting arms 16A and 16B are always the same. In addition, the pair of rotating arms 3A and 3B are rotated. The spacers 21 are integrally formed on the periphery of the attachment holes 19 of the connecting arms 16A and 16B.

また、各連結アーム16A,16Bの基端部における回動中心を挟んだ対称位置には、一対の突起部32,32がそれぞれ一体形成される一方で、ベースプレート4の長手方向両側の各端部には、該一対の突起部32にそれぞれ当接して該連結アーム16A,16B及び回動軸2A,2Bの動きを一部で規制する一対の規制部33がそれぞれ一体形成されている。   In addition, a pair of protrusions 32 and 32 are integrally formed at symmetrical positions with the rotation center at the base end of each of the connecting arms 16A and 16B, respectively, while the end portions on both sides in the longitudinal direction of the base plate 4 are formed. A pair of restricting portions 33 that respectively abut against the pair of protrusions 32 and restrict the movements of the connecting arms 16A and 16B and the rotating shafts 2A and 2B are formed integrally.

この突起部32,32と、規制部33,33との接当による規制作用によって、開き角θが所定範囲内(図示する例では90度程度)に収まっている際に、作動ピン29,29が、作動ガイド孔31A,31Bから、該作動ガイド孔31A,31Bに連続している長孔12A,12Bに移動することを、効率的に規制できる。   When the opening angle θ is within a predetermined range (about 90 degrees in the illustrated example) due to the restricting action by the contact between the projecting portions 32 and 32 and the restricting portions 33 and 33, the operating pins 29 and 29 However, the movement from the operation guide holes 31A and 31B to the long holes 12A and 12B continuous to the operation guide holes 31A and 31B can be efficiently regulated.

さらに、この二軸ヒンジ装置1では、ベースプレート4における位置決め部材6A,6B(図1乃至図3参照)との対向面には、回動軸2A,2Bの軸回りにほぼ1/4周間隔毎に凹状の嵌合部26を設け、皿バネ27(図1乃至図3参照)折畳状態と展開状態の2つの状態時に位置決め部材6A,6Bによる位置決めを行う。ちなみに、上述した通り、凸部24及び凹部26の位相をずらして、ガタを防止させてもよい。   Further, in this biaxial hinge device 1, the surface of the base plate 4 facing the positioning members 6A and 6B (see FIGS. 1 to 3) is arranged at intervals of approximately 1/4 turn around the rotation shafts 2A and 2B. A concave fitting portion 26 is provided in the disc spring 27 (see FIGS. 1 to 3), and positioning is performed by the positioning members 6A and 6B in two states, a folded state and a deployed state. Incidentally, as described above, the phases of the convex portions 24 and the concave portions 26 may be shifted to prevent backlash.

図10(A)は折畳状態に切換えられた二軸ヒンジ装置の要部側面図であり、(B)は折畳状態から展開状態に切換えられる途中の二軸ヒンジ装置の要部側面図であり、(C)は展開状態に切換えられた二軸ヒンジ装置の要部側面図である。   FIG. 10A is a side view of the main part of the biaxial hinge device switched to the folded state, and FIG. 10B is a side view of the main part of the biaxial hinge device being switched from the folded state to the expanded state. (C) is a side view of the main part of the biaxial hinge device switched to the unfolded state.

この二軸ヒンジ装置1では、一対の筐体A,Bの折畳状態時、各作動ピン29,29は、円弧状の作動ガイド孔31A,31Bの一端側に位置し、作動ピン29,29間の距離が最小になり、これに伴って、回動軸2A,2B間の距離も最小になる(同図A参照)。   In the biaxial hinge device 1, when the pair of housings A and B are folded, the operation pins 29 and 29 are located on one end side of the arcuate operation guide holes 31 </ b> A and 31 </ b> B. The distance between the rotating shafts 2A and 2B is also minimized (see FIG. A).

そして、各連結アーム16,16Bのアーム回動角αが0度から45度(開き角が0度から90度)になるように、一対の筐体A,Bを回動させると、各作動ピン29,29は、円弧状の作動ガイド孔31A,31Bの中間部分に達して作動ピン29間の距離が最大になり、これに伴って、回動軸2A,2B間の距離も最大になる。   When the pair of casings A and B are rotated so that the arm rotation angle α of each of the connecting arms 16 and 16B is 0 degree to 45 degrees (the opening angle is 0 degree to 90 degrees), The pins 29 and 29 reach the intermediate portions of the arcuate operation guide holes 31A and 31B, and the distance between the operation pins 29 is maximized, and accordingly, the distance between the rotation shafts 2A and 2B is also maximized. .

続けて、各連結アーム16,16Bのアーム回動角αが45度から90度(開き角が90度から180度)になるように、一対の筐体A,Bを回動させると、各作動ピン29,29は、円弧状の作動ガイド孔31A,31Bの他端側に達して作動ピン29間の距離が再び最小になり、これに伴って、回動軸2A,2B間の距離も再度最小になる。   Subsequently, when the pair of casings A and B are rotated so that the arm rotation angle α of each of the connecting arms 16 and 16B is 45 degrees to 90 degrees (the opening angle is 90 degrees to 180 degrees), The operating pins 29 and 29 reach the other end side of the arc-shaped operating guide holes 31A and 31B, and the distance between the operating pins 29 is minimized again. Accordingly, the distance between the rotating shafts 2A and 2B is also reduced. Minimize again.

このような作動ピン29,29による回動軸2A,2Bの離間・近接作動は、一対の作動ガイド孔31A,31Bの形状によって、細かく設定される。図示する例では、一対の作動ガイド孔31A,31Bの間の距離が、該作動ガイド31A,31Bの両端側で最小となり、中間側に向かって次第に大きくなっていくため、上述のような離間・近接作動になる。   Such separation / proximity operation of the rotation shafts 2A and 2B by the operation pins 29 and 29 is finely set according to the shape of the pair of operation guide holes 31A and 31B. In the example shown in the figure, the distance between the pair of operation guide holes 31A and 31B is minimum on both end sides of the operation guides 31A and 31B and gradually increases toward the intermediate side. Proximity operation.

このように、作動ガイド孔31A,31Bの形状を適宜変更することにより、回動軸2A,2Bの離間・近接作動の態様を、回動軸2A,2Bの回動位置毎に詳細に設定できるため、利便性が高い。ちなみに、その間、連結ピン21もスライド孔17c内をスライド移動し、連結ピン21,21間の距離の変化が許容される。   In this way, by appropriately changing the shapes of the operation guide holes 31A and 31B, the mode of separation / proximity operation of the rotation shafts 2A and 2B can be set in detail for each rotation position of the rotation shafts 2A and 2B. Therefore, convenience is high. Incidentally, during that time, the connecting pin 21 also slides in the slide hole 17c, and the change in the distance between the connecting pins 21 and 21 is allowed.

次に、図12乃至図18に基づき二軸ヒンジ装置1の別実施形態について上述した例と異なる点を説明する。
図12は、二軸ヒンジ装置の別実施形態を示す分解斜視図であり、図13は、図11の要部斜視図である。上述した例では、作動ガイド孔31A,31Bを、ベースプレート4に形成する例について説明したが、同図に示す例では、作動ガイド孔31A,31Bを形成するガイドプレート(ガイド部材)34を、ベースプレート4とは別体で設けている。
Next, a different point from the example mentioned above about another embodiment of biaxial hinge device 1 is explained based on Drawing 12 thru / or Drawing 18.
12 is an exploded perspective view showing another embodiment of the biaxial hinge device, and FIG. 13 is a perspective view of a main part of FIG. In the above-described example, the operation guide holes 31A and 31B are formed in the base plate 4. However, in the example shown in the figure, the guide plate (guide member) 34 that forms the operation guide holes 31A and 31B is replaced with the base plate. 4 is provided separately.

ガイドプレート34は、ベースプレート4を挟んで、回動アーム3A,3Bの反対側に配置されている。このガイドプレート34は、長手方向がベースプレート4の全長方向に向けられ且つ該ベースプレート4と平行に対向している。   The guide plate 34 is disposed on the opposite side of the rotating arms 3A and 3B with the base plate 4 interposed therebetween. The guide plate 34 has a longitudinal direction facing the entire length direction of the base plate 4 and faces the base plate 4 in parallel.

このベースプレート4及びガイドプレート34の対向面側には、互いに凹凸嵌合する嵌合部36,37が形成され、この嵌合部36,37によって、ガイドプレート34とベースプレート4を嵌合させると、対向面の間に隙間が形成されるボックス状をなし、この隙間に、前記した一対の連結アーム16A,16Bが介挿される。   On the opposite surface side of the base plate 4 and the guide plate 34, fitting portions 36 and 37 are formed to be engaged with each other, and when the guide plate 34 and the base plate 4 are fitted by the fitting portions 36 and 37, A box shape is formed in which a gap is formed between the opposing surfaces, and the pair of connecting arms 16A and 16B are inserted in the gap.

この隙間内に位置する連結アーム16A,16Bの取付孔19,19には、回動軸2A,2Bの基端側に形成された小径の基端寄り取付部9d,9dが嵌合挿入され、この回動軸2A,2Bは、ベースプレート34に穿設された一対の長孔12A,12Bにそれぞれ挿通される。   In the mounting holes 19 and 19 of the connecting arms 16A and 16B located in the gap, small-diameter proximal end mounting portions 9d and 9d formed on the proximal end sides of the rotating shafts 2A and 2B are fitted and inserted. The rotation shafts 2A and 2B are inserted through a pair of long holes 12A and 12B formed in the base plate 34, respectively.

この回動軸2A,2Bの中途側取付部9c及び先端側取付部9aは、ベースプレート34から回動アーム3A,3B側に突出し、この中途側取付部9cには、位置決め部材6A,6B及び皿バネ27が挿通して取付けられている。この位置決め部材6A,6B及び複数の皿バネ27の周囲には、回動軸2A,2B毎にカバー体38が外装されている。   The mid-side mounting portion 9c and the tip-side mounting portion 9a of the rotating shafts 2A and 2B protrude from the base plate 34 toward the rotating arms 3A and 3B. The mid-side mounting portion 9c includes positioning members 6A and 6B and a dish. A spring 27 is inserted and attached. Around the positioning members 6A and 6B and the plurality of disc springs 27, a cover body 38 is externally provided for each of the rotation shafts 2A and 2B.

The distal end side attachment portions 9a of the rotation shafts 2A and 2B protruding from the insertion holes 38a toward the rotation arms 3A and 3B are fitted and inserted into the attachment holes 13 of the rotation arms 3A and 3B and fixed.

このようにして回動軸2A,2Bの両端部に回動アーム3A,3B及び連結アーム16A,16Bが嵌合挿入されると、カバー体38、皿バネ27及び位置決め部材6A,6Bがベースプレート4側に装着され、皿バネ27の弾性力によって、位置決め部材6A,6Bの上述した嵌合部24が、ベースプレート4の前記嵌合部26に凹凸嵌合した状態になる。   In this way, when the rotary arms 3A, 3B and the connecting arms 16A, 16B are fitted and inserted into both ends of the rotary shafts 2A, 2B, the cover body 38, the disc spring 27, and the positioning members 6A, 6B are connected to the base plate 4. The fitting portion 24 of the positioning members 6 </ b> A and 6 </ b> B is in an unevenly fitted state with the fitting portion 26 of the base plate 4 by the elastic force of the disc spring 27.

図14は、ベースプレート及びガイドプレートの斜視図である。図12乃至図14に示す通り、ベースプレート4及びガイドプレート34の一方側の嵌合部36はスペーサ部36a及び該スペーサ部36aに一体形成された凸部36bから構成され、他方側の嵌合部37は凹部によって構成され、この凹部37と凸部36bを凹凸嵌合させると、スペーサ部36aの分だけ、ベースプレート4bとガイドプレート34の間に隙間が形成される。   FIG. 14 is a perspective view of the base plate and the guide plate. As shown in FIGS. 12 to 14, the fitting portion 36 on one side of the base plate 4 and the guide plate 34 is composed of a spacer portion 36a and a convex portion 36b formed integrally with the spacer portion 36a, and the fitting portion on the other side. 37 is constituted by a concave portion, and when the concave portion 37 and the convex portion 36b are engaged with each other, a gap is formed between the base plate 4b and the guide plate 34 by the amount of the spacer portion 36a.

ベースプレート4及びガイドプレート34には、上記ガイド孔11が穿設され、このガイドプレート34を挟んだベースプレート4の反対側に連結ロッド17が配置されている。連結ロッド17には、上述した融通手段を構成する長孔状のスライド孔17cが一対設けられ、この一対のスライド孔17c,17cの間には、ベースプレート4及びガイドプレート34側に突出するガイドピン18が一体形成されている。   The base plate 4 and the guide plate 34 are provided with the guide holes 11, and the connecting rod 17 is disposed on the opposite side of the base plate 4 with the guide plate 34 interposed therebetween. The connecting rod 17 is provided with a pair of long hole-like slide holes 17c that constitute the above-mentioned accommodation means, and a guide pin that protrudes toward the base plate 4 and the guide plate 34 between the pair of slide holes 17c, 17c. 18 is integrally formed.

このガイドプレート34における連結ロッド17側の長手方向両端部には、ガイド孔11と平行な係合レール39,39がそれぞれ凸状形成される一方で、該連結ロッド17の両端部には、この係合レール39,39とスライド自在に係合する係合溝17d、17dがそれぞれ凹設されている。この一対の係合レール39,39に一対の係合溝17d、17dをスライド自在に係合させることにより、連結ロッド17が、ガイド孔11の方向に摺動自在に、ガイドプレート34に係合支持される。   Engagement rails 39 and 39 parallel to the guide hole 11 are formed at both ends of the guide plate 34 in the longitudinal direction on the side of the connecting rod 17, respectively. Engagement grooves 17d and 17d, which are slidably engaged with the engagement rails 39 and 39, are respectively recessed. By slidably engaging the pair of engagement grooves 17d, 17d with the pair of engagement rails 39, 39, the connecting rod 17 is slidably engaged with the guide plate 34 in the direction of the guide hole 11. Supported.

この係合状態において、連結ロッド17に一体形成されたガイドピン18は、ガイドプレート34及びベースプレート4に穿設されたガイド孔11,11に挿通され、このようにしてベースプレート4から回動アーム3A,3B側に突出したガイドピン18の先端部には、抜け止用のリング41が嵌合挿入されて取付けられる。   In this engaged state, the guide pin 18 formed integrally with the connecting rod 17 is inserted through the guide holes 11 and 11 drilled in the guide plate 34 and the base plate 4, and in this way from the base plate 4 to the rotating arm 3 </ b> A. A ring 41 for retaining is fitted and attached to the tip of the guide pin 18 protruding to the 3B side.

ガイドプレート34に穿設された一対の作動ガイド孔31A,31Bはガイド孔11を境に互いが対称形状をなすとともに、各作動ガイド孔31A,31Bはガイド孔11の中央側で互いの距離が短くなるくの字状に形成され、この各作動ガイド孔31A,31Bは、ガイド孔11の中央で該ガイド孔11に直交する直線に対して対称形状をなしている。   The pair of operation guide holes 31A and 31B drilled in the guide plate 34 are symmetrical with each other with the guide hole 11 as a boundary, and each operation guide hole 31A and 31B has a mutual distance at the center side of the guide hole 11. The operation guide holes 31 </ b> A and 31 </ b> B are symmetrical with respect to a straight line perpendicular to the guide hole 11 at the center of the guide hole 11.

さらに詳しく説明すると、各作動ガイド孔31A,31Bの中央部を境にした一方側半部が、開き角θが0〜180度の間で、筐体A,Bが回動する際の案内範囲である第1ガイド範囲42であり、他方側半部が、開き角θが180〜360度の間で、筐体A,Bが回動する際の案内範囲である第2ガイド範囲43であり、この第1ガイド範囲42と第2ガイド範囲43との接続部分が折返し部44になる。この2つの各ガイド範囲42,43は、折返し部44から遠ざかる程、ガイド孔11側に湾曲し、ガイド孔11が最も遠ざかるガイド範囲43,43の端側では、ガイド孔11に沿って略平行な状態になる。   More specifically, the guide range when the casings A and B rotate while the opening half angle θ is between 0 and 180 degrees on one half of the operation guide holes 31A and 31B at the center. Is the first guide range 42, and the other half is the second guide range 43 which is the guide range when the casings A and B rotate with the opening angle θ between 180 and 360 degrees. The connecting portion between the first guide range 42 and the second guide range 43 is a folded portion 44. The two guide ranges 42 and 43 are curved toward the guide hole 11 as the distance from the turn-back portion 44 is increased, and are approximately parallel along the guide hole 11 at the end side of the guide ranges 43 and 43 where the guide hole 11 is farthest away. It becomes a state.

一対の連結アーム16A,16Bの先端側に一体で突出形成された連結ピン20,20は、対応する作動ガイド孔31A,31B及びスライド孔17c,17dに挿通され、各連結ロッド17から突出した連結ピン20の先端部には、抜け止用のリング46が嵌合挿入されて固定されている。   The connection pins 20, 20 formed integrally and projecting on the distal end side of the pair of connection arms 16 A, 16 B are inserted into the corresponding operation guide holes 31 A, 31 B and slide holes 17 c, 17 d and connected from the connection rods 17.

(C) is a main part side view of the biaxial hinge device when the opening angle is 180 degrees, FIG. 16 (A) is a main part side view of the biaxial hinge device when the opening angle is 270 degrees, (B) is a principal part side view of a biaxial hinge apparatus in case an opening angle is 360 degree | times.

開き角θが0度となる筐体A,Bの折畳み状態では、各連結ピン20は、第1ガイド範囲42の折返し部44から遠い端部に位置し、回動アーム3A,3B及び連結アーム16A,16Bはガイド孔11の方向に沿った(具体的には平行な)状態になる(図15(A)参照)。   In the folded state of the casings A and B where the opening angle θ is 0 degree, each connecting pin 20 is located at an end portion of the first guide range 42 far from the folded portion 44, and the rotating arms 3A and 3B and the connecting arm 16A and 16B are in a state along the direction of the guide hole 11 (specifically, parallel) (see FIG. 15A).

開き角θが90度となる筐体A,Bの折畳み状態から展開状態への切換の最中では、各連結ピン20は、第1ガイド範囲42の端部から折返し部44に至る中途部分に位置し、回動アーム3A,3B及び連結アーム16A,16Bは、ガイド孔11方向に対して若干外側に開いた状態になり、回動軸2A,2Bの間の距離である前記軸間距離Dが、開き角度θが0度の場合に比べて長くなる(図15(B)参照)。   During the switching from the folded state to the unfolded state of the casings A and B with the opening angle θ of 90 degrees, each connecting pin 20 is in the middle of the first guide range 42 from the end to the folded portion 44. The pivot arms 3A and 3B and the connecting arms 16A and 16B are slightly opened outward with respect to the guide hole 11, and the inter-axis distance D, which is the distance between the pivot shafts 2A and 2B. However, it becomes longer than the case where the opening angle θ is 0 degree (see FIG. 15B).

開き角θが180度となる筐体A,Bの展開状態では、各連結ピン20は、折返し部44に位置し、回動アーム3A,3B及び連結アーム16A,16Bは、ガイド孔11方向に対して垂直に外側に開いた状態になり、回動軸2A,2Bの間の距離である前記軸間距離Dが、開き角度θが90度の場合に比べて短くなる(図15(C)参照)。ちなみに、一対の連結アーム16A,16Bは、互いに離間する方向に開くが、この場合に隣接する折返し部44,44の間の距離を短くしたため、軸間距離Dを短くできる。   In the unfolded state of the casings A and B where the opening angle θ is 180 degrees, each connecting pin 20 is positioned in the folded portion 44, and the rotating arms 3A and 3B and the connecting arms 16A and 16B are directed in the direction of the guide hole 11. On the other hand, the distance between the pivot shafts 2A and 2B is perpendicular to the outside, and the distance D between the shafts is shorter than when the opening angle θ is 90 degrees (FIG. 15C). reference). Incidentally, the pair of connecting arms 16A and 16B open in a direction away from each other. In this case, the distance between the adjacent folded portions 44 and 44 is shortened, so that the inter-axis distance D can be shortened.

開き角θが270度となる筐体A,Bの展開状態から折畳み状態への切換の最中では、各連結ピン20は、折返し部44から第2ガイド範囲43の端部に至る中途部分に位置し、回動アーム3A,3B及び連結アーム16A,16Bは、ガイド孔11方向に対して若干外側に開いた状態になり、回動軸2A,2Bの間の距離である前記軸間距離Dが、開き角度θが180度の場合に比べて長くなる(図16(A)参照)。   During the switching from the expanded state to the folded state of the casings A and B where the opening angle θ is 270 degrees, each connecting pin 20 is in the middle of the folded portion 44 to the end of the second guide range 43. The pivot arms 3A and 3B and the connecting arms 16A and 16B are slightly opened outward with respect to the guide hole 11, and the inter-axis distance D, which is the distance between the pivot shafts 2A and 2B. However, the opening angle θ is longer than that when the opening angle θ is 180 degrees (see FIG. 16A).

開き角θが360度となる筐体A,Bの折畳み状態では、各連結ピン20は、第2ガイド範囲42の折返し部44から遠い端部に位置し、回動アーム3A,3B及び連結アーム16A,16Bはガイド孔11の方向に沿った(具体的には平行な)状態になる(図16(B)参照)。   In the folded state of the casings A and B with an opening angle θ of 360 degrees, each connecting pin 20 is positioned at an end portion far from the folded portion 44 of the second guide range 42, and the rotating arms 3A and 3B and the connecting arms 16A and 16B are in a state along the direction of the guide hole 11 (specifically, parallel) (see FIG. 16B).

図17及び図18は、回動軸と位置決め部材のガタを防止するガタ防止機構の構成を示す要部正断面図及び要部側断面図である。各回動軸2A,2Bの外周と、該回動軸2A,2Bが挿通される位置決め部材6A,6Bの内周との間には、ガタ防止機構が介挿されている。   FIG. 17 and FIG. 18 are a main part front sectional view and a main part side sectional view showing a configuration of a backlash prevention mechanism for preventing backlash between the rotation shaft and the positioning member. A backlash prevention mechanism is interposed between the outer periphery of each of the rotation shafts 2A and 2B and the inner periphery of the positioning members 6A and 6B through which the rotation shafts 2A and 2B are inserted.

具体的には、回動軸6A,6Bの外周面のフラットに切欠かれた部分と、位置決め部材6A,6Bの取付孔23の内周面との間に配置されて球状に成形された金属製(具体的には鉄製)のガタ防止部材47と、ガタ防止部材47が収容されるように取付孔23の内周面に凹状形成された収容溝(収容スペース)23aとによって、ガタ防止機構を構成している。   Specifically, it is made of a metal that is disposed between a portion of the outer peripheral surface of the rotating shafts 6A and 6B that is cut out in a flat shape and an inner peripheral surface of the mounting hole 23 of the positioning members 6A and 6B and is formed into a spherical shape. The backlash prevention mechanism 47 includes a backlash prevention member 47 (specifically made of iron) and a storage groove (accommodation space) 23a formed in a concave shape on the inner peripheral surface of the mounting hole 23 so that the backlash prevention member 47 is received. It is composed.

収容溝23aは、皿バネ27の弾性力の作用方向(回動軸2A,2Bの皿バネ27から位置決め部材6A,6B)に向かって深さが浅くなるテーパ状に形成されるとともに、収容溝23aの皿バネ27側端が開放されている。このため、収容溝23aに収容されたガタ防止部材47は、皿バネ27によって弾性的に押圧され、収容溝23aのテーパ面に沿って回動軸2A,2B側に弾性的に付勢される。   The accommodation groove 23a is formed in a tapered shape whose depth becomes shallower toward the acting direction of the elastic force of the disc spring 27 (from the disc spring 27 of the rotation shafts 2A and 2B to the positioning members 6A and 6B). The disc spring 27 side end of 23a is open | released. For this reason, the backlash prevention member 47 accommodated in the accommodation groove 23a is elastically pressed by the disc spring 27, and is elastically biased toward the rotation shafts 2A and 2B along the tapered surface of the accommodation groove 23a. .

この弾性付勢によって、位置決め部材6A,6Bの取付孔23の内周と、回動軸2A,2Bの外周との間に形成される隙間に起因したガタが防止され、筐体A,Bが上述した各姿勢で、確実に位置決めされる。   This elastic bias prevents backlash caused by a gap formed between the inner periphery of the mounting hole 23 of the positioning members 6A and 6B and the outer periphery of the rotation shafts 2A and 2B. Positioning is ensured in each of the above-described postures.

ちなみに、回動軸2A,2Bの位置決め部材6A,6Bを挿通させる部分には、1/4周間隔毎にフラットな切欠き面が形成されているため、各位置決め部材6A,6Bに対して、収容溝23a及びガタ防止部材47が切欠き面の数と同数の4つ用意される。   By the way, since the flat cut-out surface is formed at intervals of ¼ circumference in the portions through which the positioning members 6A and 6B of the rotating shafts 2A and 2B are inserted, for each positioning member 6A and 6B, Four accommodation grooves 23a and a backlash prevention member 47 are prepared in the same number as the number of cutout surfaces.
