Description

ダンパーヒンジDamper hinge
　本発明は、筐体と蓋の如き２つの物体を相対的に枢動するように結合するダンパーヒンジに関するものである。 The present invention relates to a damper hinge that couples two objects such as a casing and a lid so as to pivot relative to each other.
　この種のダンパーヒンジにおいて、ヒンジ本体内に２つのダンパーを配置して構成されているものがあるが（特許文献１、２参照）、これらのダンパーヒンジは、いずれも、ヒンジ本体の相対回転に応じて２つのダンパーが同時に作用してダンパートルクを重畳するだけであった。 Some damper hinges of this type are configured by arranging two dampers in the hinge body (see Patent Documents 1 and 2), and these damper hinges are all used for relative rotation of the hinge body. In response, the two dampers acted simultaneously to merely superimpose the damper torque.
　例えば、特許文献１（特開平７-２８６４７２号公報）に記載のダンパーヒンジは、固定側翼板４の軸筒（ヒンジ本体）内に背合わせして挿入された２つのダンパー１を備え、これらのダンパー１のステータ２は、その多角外周面を軸筒の相応する多角内周面に係合して軸筒と共に一緒に回転するようにし、ロータ３は、軸筒の端部から突出して可動側翼板６のアーム８の軸孔に同様に多角面で係合している。可動側翼板６が例えば固定側翼板４から離れる方向（開く方向）に枢動する際には、ダンパー１のロータ３は、小さなダンパートルクで回動し、可動側翼板６が逆方向（閉じる方向）に枢動する際には、ダンパー１のロータ３は、大きなダンパートルクで回動して衝撃を緩和している。従って、このダンパーヒンジは、２つのダンパーが固定部と可動部との間で同時にダンパー力が作用して大きなトルクを得ることができる。これは、特許文献２（特開２００１－１９３３３９号公報）のダンパーヒンジも同様である。 For example, a damper hinge described in Patent Document 1 (Japanese Patent Laid-Open No. 7-286472) includes two dampers 1 inserted back-to-back in a shaft cylinder (hinge body) of the fixed side blade 4, and these The stator 2 of the damper 1 engages with the corresponding polygonal inner peripheral surface of the shaft cylinder so as to rotate together with the shaft cylinder, and the rotor 3 projects from the end of the shaft cylinder to move the movable side blades. Similarly, the shaft hole of the arm 8 of the plate 6 is engaged with a polygonal surface. For example, when the movable side blade 6 pivots in a direction away from the fixed side blade 4 (opening direction), the rotor 3 of the damper 1 rotates with a small damper torque, and the movable side blade 6 reverses (closes direction). ), The rotor 3 of the damper 1 is rotated by a large damper torque to reduce the impact. Therefore, this damper hinge can obtain a large torque by the damper force acting simultaneously between the fixed portion and the movable portion of the two dampers. The same applies to the damper hinge of Patent Document 2 (Japanese Patent Laid-Open No. 2001-193339).
　一方、最近、内部に弁機構を設けてロータがケーシング（ステータ）に対して一方の方向に回動する時には、弁が開いて小さな流体抵抗が得られるが、ロータがステータに対して反対方向に回動する時には、弁が閉じて流体がロータとステータとの間のオリフィスを介して大きな流体抵抗が付与されるようにした回転ダンパーが提案されている（特許文献３参照）。 On the other hand, recently, when a valve mechanism is provided inside and the rotor rotates in one direction with respect to the casing (stator), the valve opens and a small fluid resistance is obtained, but the rotor is in the opposite direction to the stator. There has been proposed a rotary damper in which a valve is closed and a fluid is given a large fluid resistance via an orifice between a rotor and a stator when rotating (see Patent Document 3).
　特許文献３（ＷＯ２０１１／０３９９２２号公報）に開示の回転ダンパーは、ロータ２がケーシング１（ステータ）内に回転自在に配置され、ケーシング１内に２つの室６Ａ、６Ｂを区画するピストン３が設けられ、２つの室６Ａ、６Ｂの間にはケーシング１内に充填された流体の流路を開閉する弁機構７が設けられ、またロータ２とピストン３との間に２つのカム機構８、９が設けられ、これらのカム機構８、９によってロータ２の回転に伴ってピストン３を軸線移動して弁機構７を開閉するようになっている。 In the rotary damper disclosed in Patent Document 3 (WO2011 / 039922), the rotor 2 is rotatably disposed in the casing 1 (stator), and the piston 3 that partitions the two chambers 6A and 6B is provided in the casing 1. A valve mechanism 7 is provided between the two chambers 6A and 6B to open and close the flow path of the fluid filled in the casing 1, and the two cam mechanisms 8 and 9 are provided between the rotor 2 and the piston 3. These cam mechanisms 8 and 9 open and close the valve mechanism 7 by axially moving the piston 3 as the rotor 2 rotates.
　この回転ダンパーにおいては、２つのカム機構８、９は、ロータ２を一方向に回動する際には、弁機構７を開く方向にピストン３を移動して小さな抵抗でロータを回動し、ロータ２を逆方向に回動する際には、弁機構７を閉じる方向にピストン３を移動し、従って、流体は、ロータ２とケーシング１との間の隙間（オリフィス）を介して移動してロータ２の回動に大きな抵抗を付与している。 In this rotary damper, when rotating the rotor 2 in one direction, the two cam mechanisms 8 and 9 move the piston 3 in the direction to open the valve mechanism 7 and rotate the rotor with a small resistance. When the rotor 2 is rotated in the reverse direction, the piston 3 is moved in the direction in which the valve mechanism 7 is closed, so that the fluid moves through the gap (orifice) between the rotor 2 and the casing 1. A large resistance is given to the rotation of the rotor 2.
　この種の回転ダンパーは、大きなダンパー力を得るために、２つのカム機構がそれぞれ対をなしているため、ロータの回動角度を大きくすることができない欠点があった。 This type of rotary damper has the disadvantage that the rotational angle of the rotor cannot be increased because the two cam mechanisms are paired to obtain a large damper force.

　本発明が解決しようとする課題は、回転ダンパーの限界回動角度を越えて大きな枢動角度を得ることができるダンパーヒンジを提供することにある。 The problem to be solved by the present invention is to provide a damper hinge capable of obtaining a large pivot angle exceeding the limit rotation angle of the rotary damper.
　本発明の課題解決手段は、相互に枢動自在に結合すべき２つの物体の一方の物体に取り付けられるべき第１のヒンジ本体と、他方の物体に取り付けられるべき第２のヒンジ本体と、前記第１のヒンジ本体に回転軸とケースのいずれか一方が非回転状態で係入する第１の回転ダンパーと、前記第２のヒンジ本体に回転軸とケースのいずれか一方が非回転状態で係入する第２の回転ダンパーと、前記第１の回転ダンパーの回転軸とケースのいずれか他方が一端部に非回転状態で係入すると共に前記第２の回転ダンパーの回転軸とケースのいずれか他方が他端部に非回転状態で係入する連結環とを備えていることを特徴とするダンパーヒンジを提供することにある。 The problem-solving means of the present invention includes a first hinge body to be attached to one object of two objects to be pivotally coupled to each other, a second hinge body to be attached to the other object, A first rotating damper in which either the rotating shaft or the case is engaged with the first hinge body in a non-rotating state, and either the rotating shaft or the case is engaged with the second hinge body in a non-rotating state. The second rotary damper to be inserted, the rotary shaft of the first rotary damper, and the other of the case are engaged with one end in a non-rotating state, and the rotary shaft of the second rotary damper and the case are either Another object of the present invention is to provide a damper hinge characterized in that the other is provided with a connecting ring engaged with the other end portion in a non-rotating state.
　本発明の課題解決手段において、前記連結環は、前記第１と第２のヒンジ本体内に跨って配置することができ、また、前記第１のヒンジ本体と前記連結環の相応する端部との間に設けられて前記第１のヒンジ本体と前記連結環とを第１の所定の許容回動角度で相対回転する第１の回動許容手段と、前記第２のヒンジ本体と前記連結環の相応する端部との間に設けられて前記第２のヒンジ本体と前記連結環とを第２の所定の許容回動角度で相対回転する第２の回動許容手段とを更に備えているのが好ましい。 In the problem-solving means of the present invention, the connecting ring can be disposed across the first and second hinge bodies, and the first hinge body and a corresponding end of the connecting ring; A first rotation permitting means provided between the first hinge body and the connection ring for relative rotation at a first predetermined allowable rotation angle; the second hinge body and the connection ring; And a second rotation allowing means for rotating the second hinge body and the connecting ring relative to each other at a second predetermined allowable rotation angle. Is preferred.
　本発明の課題解決手段において、第１と第２の回転ダンパーのダンパー力は同じでもよいし、異なってもよいが、いずれの場合にも、第１と第２の回動許容手段は、第１と第２の許容回動角度が第１と第２の回転ダンパーの許容回動角度内でそれぞれ設定されていてそれを越えると、第１と第２のヒンジ本体と連結環とが回動方向に一体化する機能を有し、従って第１と第２の回転ダンパーは、連結環を介して回動角度を重畳して第１と第２のヒンジ本体間の枢動角度を大きくすることができる。 In the problem solving means of the present invention, the damper forces of the first and second rotary dampers may be the same or different. In either case, the first and second rotation permitting means are When the first and second permissible rotational angles are set within the permissible rotational angles of the first and second rotary dampers, and exceed them, the first and second hinge bodies and the connecting ring rotate. The first and second rotary dampers have a function of integrating in the direction, and thus the pivot angle between the first and second hinge bodies is increased by overlapping the pivot angle via the connecting ring. Can do.
　また、第１と第２の回転ダンパーのダンパー力が異なる場合には、前記第１と第２の回動許容手段は、ダンパー力の小さい回転ダンパーを有するヒンジ本体側が許容回動角度に達した後、ダンパー力の大きい回転ダンパーを有するヒンジ本体側の回転ダンパーを介して回動許容角度まで回動するように作動する。 In addition, when the damper forces of the first and second rotating dampers are different, the first and second rotation permitting means reach the allowable rotation angle on the hinge body side having the rotating damper having a small damper force. Then, it operates so as to rotate to a rotation allowable angle via a rotation damper on the hinge body side having a rotation damper having a large damper force.
　第１及び第２の回動許容手段は、前記第１及び第２のヒンジ本体の連結環が相対回転する部分にそれぞれ設けられたヒンジ本体側の第１と第２のヒンジ側突部と前記連結環の第１と第２のヒンジ本体に相応する端部にそれぞれ設けられた第１と第２の連結環側突部とから成っており、前記第１と第２の許容回動角度は、前記ヒンジ本体側のヒンジ側突部と前記連結環側の相応する第１と第２の連結環突部との回動方向の間隔で設定することができる。 The first and second rotation permitting means include first and second hinge-side protrusions on the hinge body side provided at portions where the connection rings of the first and second hinge bodies are relatively rotated, respectively, The connecting ring includes first and second connecting ring side protrusions provided at ends corresponding to the first and second hinge bodies of the connecting ring, respectively. The hinge-side protrusion on the hinge body side and the corresponding first and second connection-ring protrusions on the connecting ring side can be set at the interval in the rotational direction.
　このようにすると、第１と第２のヒンジ本体の第１と第２の回転ダンパーを同時に又はそれぞれ順次動作しつつ第１と第２のヒンジ側突部と第１と第２の連結環側突部との間隔の和の範囲内、即ち、第１と第２の回動許容角度の和の範囲内で２つのヒンジ本体を相対的に回動するが、前記連結環は、これらの２つの回転ダンパーの動作を連携し又は切り替えて２つのヒンジ本体を連動させる機能を有する。 In this case, the first and second hinge side protrusions and the first and second connecting ring sides are operated while simultaneously or sequentially operating the first and second rotary dampers of the first and second hinge bodies. The two hinge bodies are relatively rotated within the range of the sum of the intervals between the protrusions, that is, within the range of the sum of the first and second allowable rotation angles. It has a function of linking or switching the operations of two rotary dampers to link the two hinge bodies.
　これらの回動許容手段を有する場合、前記第１と第２のヒンジ側突部は、円弧状であり、前記第１と第２の連結環側突部は、軸線方向に延びる突条とすることができ、この場合、前記第１及び第２の円弧状突部及び突条型突部は、それぞれ周方向に１８０度間隔で１対ずつ設けられているのが好ましく、また、前記第１と第２の許容回動角度は、相応する回転ダンパーの限界回転角度又はそれ以下に設定することができる。 When these rotation permission means are provided, the first and second hinge side protrusions are arc-shaped, and the first and second connecting ring side protrusions are protrusions extending in the axial direction. In this case, it is preferable that the first and second arc-shaped protrusions and the protruding protrusions are provided in pairs in the circumferential direction at intervals of 180 degrees. And the second permissible rotation angle can be set to the limit rotation angle of the corresponding rotary damper or less.
　前記連結環が前記第１と第２のヒンジ本体に跨って配置されている場合、前記第１と第２のヒンジ本体と前記連結環とを一体化するために、前記連結環の相応する端部の環状溝に係入する第１と第２の掛け止めピンを有するのが好ましい。 When the connecting ring is arranged across the first and second hinge bodies, the corresponding ends of the connecting ring are used to integrate the first and second hinge bodies and the connecting ring. It is preferable to have first and second latch pins that engage with the annular groove of the portion.

A first hinge body 20 to be attached to one object (for example, a lid), a second hinge body 40 to be attached to the other object (for example, a housing), and the first and second hinges. First and second rotary dampers 30 and 50 provided in the main bodies 20 and 40, respectively, and the first and second hinge main bodies 20 and 40 are disposed across the first and second hinge main bodies 20 and 40. 20 and 40 and a connecting ring 60 for connecting the rotary dampers 30 and 50 to each other.
（ヒンジ本体の構成）
　第１と第２のヒンジ本体２０、４０は、図示の形態では、有底の筒状部材２０Ｃ、４０Ｃとこれらの筒状部材２０Ｃ、４０Ｃにそれぞれ一体に設けられた取付け片２０Ｐ、４０Ｐとから成り、取付け片２０Ｐ、４０Ｐを相応する物体にねじ止めして固定される。図１、図２、図５、図７及び図８において符号２２、４２は、取付け片２０Ｐ、４０Ｐにそれぞれ設けられて物体にねじ止めすべきねじの貫通孔である。 (Configuration of hinge body)
In the illustrated form, the first and second hinge bodies 20 and 40 include bottomed cylindrical members 20C and 40C and attachment pieces 20P and 40P integrally provided on the cylindrical members 20C and 40C, respectively. The mounting pieces 20P and 40P are fixed to the corresponding object by screwing. 1, 2, 5, 7, and 8, reference numerals 22 and 42 denote through holes of screws that are provided on the attachment pieces 20 </ b> P and 40 </ b> P and should be screwed to an object, respectively.
（回転ダンパーの構成）
　第１と第２の回転ダンパー３０、５０は、ケース３２、５２とこれらのケース３２、５２内に回転自在に配置されて一方の回転方向には粘性流体の高い抵抗によってゆっくりと回転し、他方の回転方向には粘性流体の低い抵抗によって急速に回転する回転軸３４、５４とから成り、他方の回転方向に応じた粘性流体の低い抵抗は、一方の回転方向に対しては閉じるが他方の回転方向には開く図示しない弁機構によって付与され、一方の回転方向に応じた粘性流体の高い抵抗は、弁機構が閉じることによって回転軸３４、５４とケース３２、５２との間のオリフィスによって付与される。弁機構の開閉は、例えば、回転軸の回転方向に応じてカム機構を介して進退するピストンによって行われる。これらの回転ダンパー３０、５０の詳細な構造は、特許文献３に開示されたものと同様の構造とすることができるので、詳細な構造の説明は省略する。この種の回転ダンパーは、大きなダンパー力を得ることができるが、ケース内にカム機構、ピストン及び弁機構を含んでいるため、許容回転角度は比較的小さい。なお、許容回転角度とは、ケース３２、５２に対して回転軸３４、５４が回転可能な角度の限界値のことである。 (Rotational damper configuration)
The first and second rotary dampers 30 and 50 are rotatably arranged in the cases 32 and 52 and these cases 32 and 52, and rotate slowly in one direction of rotation due to the high resistance of the viscous fluid. In the direction of rotation of the rotating shafts 34 and 54 that rotate rapidly due to the low resistance of the viscous fluid, and the low resistance of the viscous fluid corresponding to the other direction of rotation closes to one rotation direction but the other A high resistance of the viscous fluid according to one rotation direction is given by an orifice between the rotary shafts 34 and 54 and the cases 32 and 52 when the valve mechanism is closed. Is done. The valve mechanism is opened and closed by, for example, a piston that moves forward and backward via a cam mechanism in accordance with the rotation direction of the rotating shaft. Since the detailed structure of these rotary dampers 30 and 50 can be the same as that disclosed in Patent Document 3, description of the detailed structure is omitted. Although this type of rotary damper can obtain a large damper force, the allowable rotation angle is relatively small because the case includes a cam mechanism, a piston, and a valve mechanism. The allowable rotation angle is a limit value of an angle at which the rotation shafts 34 and 54 can rotate with respect to the cases 32 and 52.
　これらの第１と第２の回転ダンパー３０、５０は、そのケース３２、５２の角型周面３２Ａ、５２Ａが相応する第１と第２のヒンジ本体２０、４０の有底筒状部材２０Ｃ、４０Ｃの奥（底側）の角孔２０ＣＡＨ、４０ＣＡＨにそれぞれ係入して第１と第２のヒンジ本体２０、４０内に非回転状態（回転不能状態）で配置されている。 These first and second rotary dampers 30 and 50 have bottomed cylindrical members 20C of the first and second hinge bodies 20 and 40 corresponding to the square peripheral surfaces 32A and 52A of the cases 32 and 52, respectively. It is engaged with the square holes 20CAH and 40CAH at the back (bottom side) of 40C, and is disposed in the first and second hinge bodies 20 and 40 in a non-rotating state (non-rotatable state).
（連結環の構成）
　第１と第２の回転ダンパー３０、５０を連結する連結環６０は、第１と第２の回転ダンパー３０、５０の回転軸３４、５４が非回転状態で係入するダンパー回転軸係入孔（角孔）６３Ｈ、６５Ｈを両端に有する。図９（Ｅ）（Ｆ）から解るように、ダンパー回転軸係入孔６３Ｈ、６５Ｈは、連続しているが、これらは、不連続であってもよい。 (Composition of connected ring)
The connecting ring 60 that connects the first and second rotary dampers 30 and 50 is a damper rotary shaft engagement hole through which the rotary shafts 34 and 54 of the first and second rotary dampers 30 and 50 are engaged in a non-rotating state. (Square holes) 63H and 65H are provided at both ends. As can be seen from FIGS. 9E and 9F, the damper rotation shaft engagement holes 63H and 65H are continuous, but they may be discontinuous.
　従って、第１と第２のヒンジ本体２０、４０は、第１と第２の回転ダンパー３０、５０のケース３２、５２と非回転状態で結合され、また第１と第２の回転ダンパー３０、５０の回転軸３４、５４は、連結環６０と非回転状態で連結され、第１と第２のヒンジ本体２０、４０は、相応する第１と第２の回転ダンパー３０、５０の回転軸３４、５４を介して連結環６０に相互に結合されている。 Accordingly, the first and second hinge bodies 20, 40 are coupled to the cases 32, 52 of the first and second rotary dampers 30, 50 in a non-rotating state, and the first and second rotary dampers 30, The rotating shafts 34 and 54 of the 50 are connected to the connecting ring 60 in a non-rotating state, and the first and second hinge bodies 20 and 40 are connected to the rotating shafts 34 of the corresponding first and second rotating dampers 30 and 50. , 54 to each other to the connecting ring 60.
（回動許容手段の説明）
　本発明のダンパーヒンジ１０は、第１のヒンジ本体２０と連結環６０の相応する端部との間に設けられて第１のヒンジ本体２０と連結環６０とを第１の所定の許容回動角度α１で相対回転する第１の回動許容手段７０と、第２のヒンジ本体４０と連結環６０の相応する端部との間に設けられて第２のヒンジ本体４０と連結環６０とを第２の所定の許容回動角度α２で相対回転する第２の回動許容手段９０とを更に備えている。 (Explanation of rotation permission means)
The damper hinge 10 of the present invention is provided between the first hinge body 20 and the corresponding end of the connecting ring 60, and allows the first hinge body 20 and the connecting ring 60 to perform a first predetermined permissible rotation. The first rotation permitting means 70 that relatively rotates at an angle α1, and the second hinge body 40 and the connection ring 60 are provided between the second hinge body 40 and the corresponding end of the connection ring 60. Second rotation permission means 90 that relatively rotates at a second predetermined allowable rotation angle α2 is further provided.
　これらの第１と第２の回動許容手段７０、９０は、第１と第２の許容回動角度α１、α２が第１と第２の回転ダンパー３０、５０の限度回動角度内でそれぞれ設定されていてそれを越えると、第１と第２のヒンジ本体２０、４０と連結環６０とが回動方向に一体化する機能を有し、従って第１と第２の回転ダンパー３０、５０は、連結環６０を介して回動角度を重畳して第１と第２のヒンジ本体３０、５０間の第１と第２の許容回動角度α１とα２との和に相応する角度まで枢動角度を大きくすることができる。 These first and second rotation permitting means 70 and 90 are such that the first and second allowable rotation angles α1 and α2 are within the limit rotation angles of the first and second rotary dampers 30 and 50, respectively. If it is set and exceeds it, the first and second hinge bodies 20 and 40 and the connecting ring 60 have a function of being integrated in the rotating direction, and therefore the first and second rotating dampers 30 and 50 are integrated. Is pivoted to the angle corresponding to the sum of the first and second allowable rotation angles α1 and α2 between the first and second hinge bodies 30 and 50 by superimposing the rotation angle via the connecting ring 60. The moving angle can be increased.
　これらの第１と第２の回動許容手段７０、９０の具体例を詳細に述べると、第１及び第２の回動許容手段７０、９０は、図７及び図８に示すように、第１及び第２のヒンジ本体２０、４０の連結環６０が嵌まり込んで（係入して）相対回転する部分にそれぞれ設けられたヒンジ本体側の第１と第２のヒンジ側突部７２Ｐ、９２Ｐ(図８参照)と、連結環６０の第１と第２のヒンジ本体２０、４０に相応する端部にそれぞれ設けられた第１と第２の連結環側突部７６Ｐ、９６Ｐ(図７参照)とから成っており、第１と第２の許容回動角度α１及びα２は、第１と第２のヒンジ側突部７２Ｐ、９２Ｐと第１と第２の連結環突部７６Ｐ、９６Ｐとの回動方向の間隔で設定される。 A specific example of the first and second rotation permitting means 70 and 90 will be described in detail. The first and second rotation permitting means 70 and 90 are, as shown in FIGS. First and second hinge-side protrusions 72P on the hinge body side provided at the portions where the connection rings 60 of the first and second hinge bodies 20 and 40 are fitted (engaged) and relatively rotated, respectively. 92P (see FIG. 8) and first and second connecting ring side protrusions 76P, 96P (FIG. 7) provided at the ends corresponding to the first and second hinge bodies 20, 40 of the connecting ring 60, respectively. The first and second allowable rotation angles α1 and α2 are defined by the first and second hinge- side protrusions 72P and 92P and the first and second connecting ring protrusions 76P and 96P. And the interval in the rotation direction.
　このようにすると、第１と第２のヒンジ本体２０、４０の相対的回動を第１と第２の回転ダンパー３０、５０を同時に又はそれぞれ順次動作しつつ行う際、第１と第２のヒンジ側突部７２Ｐ、９２Ｐと第１と第２の連結環側突部７６Ｐ、９６Ｐとの間隔の和の範囲内、即ち、第１と第２の許容回動角度α１とα２の和の範囲内で、２つのヒンジ本体２０、４０を相対的に回動し、連結環６０は、これらの２つの回転ダンパー３０、５０の動作を連携し又は切り替えて２つのヒンジ本体２０、４０を連動させる機能を有するが、この動作の詳細は、図１０乃至図１１以下を参照にて後述する。 Thus, when the first and second hinge bodies 20 and 40 are relatively rotated while the first and second rotary dampers 30 and 50 are operated simultaneously or sequentially, the first and second hinge bodies 20 and 40 are operated. Within the range of the sum of the distances between the hinge side projections 72P, 92P and the first and second connecting ring side projections 76P, 96P, that is, the range of the sum of the first and second allowable rotation angles α1 and α2. The two hinge bodies 20 and 40 are relatively rotated, and the connecting ring 60 links or switches the operations of the two rotary dampers 30 and 50 to link the two hinge bodies 20 and 40 together. Details of this operation will be described later with reference to FIGS.
　図示の形態では、第１と第２のヒンジ側突部７２Ｐ、９２Ｐは、円弧状の形態であり、第１と第２の連結環側突部７６Ｐ、９６Ｐは、軸線方向に延びる突条の形態であり、且つ、これらの第１及び第２の円弧状突部７２Ｐ、９２Ｐ及び突条型突部７６Ｐ、９６Ｐは、それぞれ周方向に１８０度間隔で１対形成されている。 In the illustrated form, the first and second hinge- side protrusions 72P and 92P are arc-shaped, and the first and second connecting ring- side protrusions 76P and 96P are protrusions extending in the axial direction. The first and second arc-shaped protrusions 72P and 92P and the protrusion-shaped protrusions 76P and 96P are formed in pairs at intervals of 180 degrees in the circumferential direction.
この場合、第１と第２の許容回動角度α１、α２は、相応する回転ダンパー３０、５０の限界回転角度又はそれ以下に設定することができる。 In this case, the first and second allowable rotation angles α1, α2 can be set to the limit rotation angle of the corresponding rotary dampers 30, 50 or less.

（ダンパーヒンジの動作説明）
　次に、本発明の第１の実施の形態によるダンパーヒンジ１０の動作を図１０及び図１１を参照して詳細に述べる。本発明のダンパーヒンジ１０の第１と第２の回転ダンパー３０、５０は、同じダンパー力を有していてもよいし、異なるダンパー力を有していてもよいが、図１０及び図１１では、第１と第２の回転ダンパー３０、５０が異なるダンパー力を有する場合の動作を示している。 (Description of damper hinge operation)
Next, the operation of the damper hinge 10 according to the first embodiment of the present invention will be described in detail with reference to FIGS. The first and second rotary dampers 30 and 50 of the damper hinge 10 of the present invention may have the same damper force or different damper forces, but in FIG. 10 and FIG. The operation when the first and second rotary dampers 30 and 50 have different damper forces is shown.
（図１０＝第１の回転ダンパー３０が第２の回転ダンパー５０よりも小さいダンパー力を有する場合）
　まず、第１のヒンジ本体２０内の回転ダンパー３０が第２ヒンジ本体４０内の回転ダンパー５０よりも小さなダンパー力を有する場合の動作を図１０を参照して述べる。図１０の（Ａ）から（Ｅ）までの図面は、第１と第２のヒンジ本体２０、４０の展開状態（第１と第２のヒンジ本体２０、４０が最も離れた状態）から、第１のヒンジ本体２０を４５度（Ｂ）、９０度（Ｃ）、１３５度（Ｄ）及び１８０度（Ｅ）回動した状態を順次示している。なお、これらの角度は、図１０（Ａ）を基準とした第１のヒンジ本体２０の反時計方向の回動角度であり、これらの角度は、第２のヒンジ本体４０に対する角度ではそれぞれ１３５度、９０度、４５度、０度となる。図１０（Ａ）は、中間にダンパーヒンジ１０の正面を示し、この中央のダンパーヒンジ１０のＥ－Ｅ線、Ｊ－Ｊ線断面図を右側に、Ｄ－Ｄ線、Ｍ－Ｍ線断面図を左側に示しており、以下図１０（Ｂ）乃至（Ｅ）も同様に中間の正面図に付された断面線に沿って切断した断面図を右及び左に示している。 (FIG. 10 = when the first rotary damper 30 has a smaller damper force than the second rotary damper 50)
First, the operation when the rotary damper 30 in the first hinge body 20 has a smaller damper force than the rotary damper 50 in the second hinge body 40 will be described with reference to FIG. 10A to 10E show the first and second hinge bodies 20 and 40 in the unfolded state (the state where the first and second hinge bodies 20 and 40 are farthest from each other). One hinge body 20 is sequentially shown rotated 45 degrees (B), 90 degrees (C), 135 degrees (D), and 180 degrees (E). These angles are the counterclockwise rotation angles of the first hinge body 20 with reference to FIG. 10A, and these angles are 135 degrees with respect to the second hinge body 40, respectively. 90 degrees, 45 degrees, and 0 degrees. FIG. 10 (A) shows the front of the damper hinge 10 in the middle, and the EE line and JJ line cross-sectional view of this central damper hinge 10 are on the right side, and the DD line and MM line cross sectional views. 10 (B) to (E) also show cross-sectional views cut along the cross-sectional line attached to the intermediate front view on the right and left.
　まず、第１のヒンジ本体２０を第２のヒンジ本体４０に対して図１０（Ａ）の右側の断面で見て反時計方向に４５度まで回動する際の状態を観察すると、左側の第２のヒンジ本体４０及びその内部の回転ダンパー５０（左側の２つの断面の斜線が施された部分及び右側の２つの断面の斜線が施されていない部分であってそのケース５２及び回転軸５４のすべて）は全く動きがなく、右側の第１のヒンジ本体２０と第１の回転ダンパー３０のケース３２とが４５度回動し、一方、回転軸３４は静止している。このとき、連結環６０も第２の回転ダンパー５０に非回転状態で結合しているので、全く動きがない。従って、第１のヒンジ本体２０の回動は、相応する第１の回転ダンパー３０のケース３２と回転軸３４との間の粘性流体による高い抵抗を受けながらゆっくりと行われる。この回動の間、第１のヒンジ本体２０側の第１のヒンジ側円弧状突部７２Ｐも回動するが、この突部７２Ｐの回転方向の縁は、まだ、連結環６０側の第１の連結環側突部７６Ｐに衝合していないので、連結環６０は、静止している。 First, when the first hinge body 20 is rotated up to 45 degrees counterclockwise when viewed from the right cross section of FIG. 10A with respect to the second hinge body 40, the left hinge Two hinge bodies 40 and a rotary damper 50 inside thereof (the left two cross-sections are hatched and the right two cross-sections are not hatched, and the case 52 and the rotary shaft 54 All) are not moving at all, and the first hinge body 20 on the right side and the case 32 of the first rotary damper 30 are rotated 45 degrees, while the rotary shaft 34 is stationary. At this time, since the connecting ring 60 is also coupled to the second rotating damper 50 in a non-rotating state, there is no movement at all. Accordingly, the first hinge body 20 is slowly rotated while receiving high resistance due to the viscous fluid between the case 32 and the rotation shaft 34 of the corresponding first rotary damper 30. During this rotation, the first hinge-side arcuate protrusion 72P on the first hinge body 20 side also rotates, but the edge in the rotation direction of the protrusion 72P is still the first ring on the connecting ring 60 side. The connecting ring 60 is stationary because it does not abut against the connecting ring side protrusion 76P.
　このようにして、第１のヒンジ本体２０が回動し図１０の（Ｃ）に示す９０度の回動角度に達すると、第１のヒンジ側円弧状突部７２Ｐの回転方向の縁が第１の連結環突部７６Ｐに衝合し、第１のヒンジ本体２０は、連結環６０に対してそれ以上回動することができない。 In this way, when the first hinge body 20 rotates and reaches the rotation angle of 90 degrees shown in FIG. 10C, the edge in the rotation direction of the first hinge-side arcuate protrusion 72P becomes the first. The first hinge body 20 abuts on the one connecting ring protrusion 76 </ b> P, and can no longer rotate with respect to the connecting ring 60.
　従って、第１のヒンジ本体２０を更に回動しようとすると、第１のヒンジ側円弧状突部７２Ｐと第１の連結環側突部７６Ｐとの衝合状態によって連結環６０も同方向に回動し、それ以後は、連結環６０の反対側に連結されている第２の回転ダンパー５０の回転軸５４を同じく粘性流体の高い抵抗を受けて回動しつつ第１のヒンジ本体２０を第２のヒンジ本体４０に対して回動する。図１０の（Ｄ）（Ｅ）で第２の回転ダンパー５０の回転軸５４が回転し、一方、ケース５２は静止しているのが判る。この際、第２の連結環側突部９６Ｐも回動し、第２のヒンジ本体４０の第２のヒンジ側円弧状突部９２Ｐの縁に近づき、第１のヒンジ本体２０が第２のヒンジ本体４０に対して１８０度回動したとき、第２の連結環側突部９６Ｐの回転方向の縁が第２のヒンジ側円弧状突部９２Ｐに衝合してそれ以上は回動することはない。 Therefore, when the first hinge body 20 is further rotated, the connecting ring 60 also rotates in the same direction due to the abutting state of the first hinge-side arcuate protrusion 72P and the first connecting-ring-side protrusion 76P. After that, the first hinge body 20 is rotated while the rotating shaft 54 of the second rotary damper 50 connected to the opposite side of the connecting ring 60 is rotated by the same high resistance of the viscous fluid. The second hinge body 40 is rotated. 10 (D) and 10 (E), it can be seen that the rotation shaft 54 of the second rotary damper 50 rotates, while the case 52 is stationary. At this time, the second connecting ring side protrusion 96P also rotates, approaches the edge of the second hinge side arc-shaped protrusion 92P of the second hinge body 40, and the first hinge body 20 moves to the second hinge. When it rotates 180 degrees with respect to the main body 40, the edge in the rotational direction of the second connecting ring side protrusion 96P abuts on the second hinge side arcuate protrusion 92P and no further rotation occurs. Absent.
　このようにして第１のヒンジ本体２０を第２のヒンジ本体４０に向けて回動（枢動）してこれらのヒンジ本体２０、４０に取り付けられた２つの物体（例えば、蓋と筐体）を閉じることができる。なお、第１のヒンジ本体２０の第２のヒンジ本体４０に対する回動は、手動で行う場合の他に、ヒンジ本体２０側の物体(例えば、蓋)に当初は手動で押し下げて回動するが、ヒンジ本体２０が傾くと、相応する物体（蓋）の重みで回動することによって行われるのが通常であり、このような自重による回動も含む。 In this way, the first hinge body 20 is rotated (pivoted) toward the second hinge body 40 and two objects (for example, a lid and a housing) attached to the hinge bodies 20 and 40 are mounted. Can be closed. Note that the first hinge body 20 is rotated manually with respect to the second hinge body 40 in addition to being manually operated, and is initially manually pushed down on the object on the hinge body 20 side (for example, a lid). When the hinge body 20 is tilted, the hinge body 20 is usually rotated by the weight of the corresponding object (lid), and includes rotation due to its own weight.
　図１０（Ｅ）の状態から第１のヒンジ本体２０を第２のヒンジ本体４０に対して離れるように回動する動作（例えば、蓋を筐体に対して開くように持ち上げる動作）は、手動などで第１のヒンジ本体２０を持ち上げて行われるが、この場合には、第１と第２の回転ダンパー３０、５０は、粘性流体の流動抵抗が低くダンパー力が働かないので、第１と第２のヒンジ本体２０、４０の相対回転は、回転ダンパー３０、５０を元の位置に戻しながら行われ、この際、第１と第２の回動許容手段７０、９０は、第１と第２のヒンジ側円弧状突部７２Ｐ、９２Ｐと第１と第２の連結環側突条突部７６Ｐ、９６Ｐとが元の位置に戻される（第１と第２のヒンジ本体２０、４０を相互に接近する方向の回動方向に対して間隔をあける位置に戻される）。 The operation of rotating the first hinge body 20 away from the second hinge body 40 from the state of FIG. 10E (for example, the operation of lifting the lid so as to open with respect to the housing) is performed manually. However, in this case, the first and second rotary dampers 30 and 50 have a low flow resistance of viscous fluid and no damper force. The relative rotation of the second hinge bodies 20 and 40 is performed while returning the rotary dampers 30 and 50 to their original positions. At this time, the first and second rotation permitting means 70 and 90 The two hinge-side arcuate protrusions 72P and 92P and the first and second connecting ring- side protrusions 76P and 96P are returned to their original positions (the first and second hinge bodies 20 and 40 are mutually connected). Is returned to a position spaced apart from the direction of rotation in the direction of approaching.
　上記の正逆動作において、連結環６０は、第１のヒンジ本体２０や第２のヒンジ本体４０に対して回動するが、第１及び第２のヒンジ本体２０、４０の掛け止めピン２６、４６は、連結環６０の相応する環状溝６２Ｇ、６４Ｇ内を相対的に移動するので、連結環６０が第１及び第２のヒンジ本体２０、４０によって干渉されることがない。 In the above-described forward / reverse operation, the connecting ring 60 rotates with respect to the first hinge body 20 and the second hinge body 40, but the latch pins 26 of the first and second hinge bodies 20, 40, 46 moves relatively in the corresponding annular grooves 62G, 64G of the connecting ring 60, so that the connecting ring 60 is not interfered by the first and second hinge bodies 20, 40.
（図１１＝第２の回転ダンパー５０が第１の回転ダンパー３０よりもダンパー力が小さい場合）
　第２のヒンジ本体４０内の回転ダンパー５０が第１のヒンジ本体２０内の回転ダンパー３０よりも小さなダンパー力を有する場合の動作は、図１１に示されている。図１１の（Ａ）から（Ｅ）までの図面は、図１０の（Ａ）から（Ｅ）までの図面と同様に表示されているので、詳細な説明は省略する。 (FIG. 11 = when the second rotating damper 50 has a smaller damper force than the first rotating damper 30)
The operation in the case where the rotary damper 50 in the second hinge body 40 has a smaller damper force than the rotary damper 30 in the first hinge body 20 is shown in FIG. Since the drawings from (A) to (E) in FIG. 11 are displayed in the same manner as the drawings from (A) to (E) in FIG. 10, detailed description thereof will be omitted.
　まず、第１のヒンジ本体２０を第２のヒンジ本体４０に対して図１１（Ａ）の右側の断面で見て反時計方向に４５度まで回動する際の状態を観察すると、左側の第２のヒンジ本体４０及びその内部の回転ダンパー５０のケース５２（左側の２つの断面の斜線が施された部分及び右側の２つの断面の斜線が施されていない部分）は全く動きがなく、右側の第１のヒンジ本体２０と第１の回転ダンパー３０のケース３２及び回転軸３４とが４５度回動している。このとき、連結環６０は、第１の回転ダンパー３０の回転軸３４に非回転状態で結合しているので、同様に４５度回動し、従って連結環６０に非回転状態で結合している第２の回転ダンパー５０の回転軸５４がその静止しているケース５２に対して回動する。このようにして、第１のヒンジ本体２０の回動は、ダンパー力が弱い方の第２の回転ダンパー５０のケース５２と回転軸５４との間の粘性流体による高い抵抗を受けながらゆっくりと行われる。この回動の間、連結環６０の第２の連結環側突部９６Ｐも回動するが、この突部９６Ｐは、まだ、第２のヒンジ本体４０側の第２のヒンジ側円弧状突部９２Ｐに衝合していないので、連結環６０は、回動を続けている。 First, when the first hinge body 20 is rotated with respect to the second hinge body 40 as viewed in the right cross section of FIG. 2 of the hinge body 40 and the case 52 of the rotary damper 50 inside thereof (the left-hatched part of the two cross-sections and the right-hand part of the two cross-sections are not hatched) do not move at all, and the right side The first hinge body 20 and the case 32 and the rotation shaft 34 of the first rotary damper 30 are rotated 45 degrees. At this time, since the connecting ring 60 is coupled to the rotating shaft 34 of the first rotary damper 30 in a non-rotating state, the connecting ring 60 is similarly rotated by 45 degrees and is thus coupled to the connecting ring 60 in a non-rotating state. The rotary shaft 54 of the second rotary damper 50 rotates with respect to the stationary case 52. Thus, the rotation of the first hinge body 20 is performed slowly while receiving high resistance due to the viscous fluid between the case 52 and the rotating shaft 54 of the second rotating damper 50 having the weaker damper force. Is called. During this rotation, the second connection ring side protrusion 96P of the connection ring 60 also rotates, but this protrusion 96P is still the second hinge side arc-shaped protrusion on the second hinge body 40 side. Since it does not collide with 92P, the connection ring 60 continues rotation.
　このようにして、第１のヒンジ本体２０が回動し図１１の（Ｃ）に示す９０度の回動角度に達すると、第２の連結環側状突部９６Ｐが第２のヒンジ側円弧状突部９２Ｐに衝合し、連結環６０は、第２のヒンジ本体４０に対してそれ以上回動することができないで静止する。 In this way, when the first hinge body 20 rotates and reaches the rotation angle of 90 degrees as shown in FIG. 11C, the second connecting ring side protrusion 96P becomes the second hinge side circle. The connection ring 60 is brought into contact with the arcuate protrusion 92P and cannot move any more with respect to the second hinge body 40 and is stationary.
　従って、第１のヒンジ本体２０を更に回動しようとすると、静止している連結環６０に非回転状態で結合しているため同じく静止している第１の回転ダンパー３０の回転軸３４を中心にして第１の回転ダンパー３０のケース３２が回転する（図１１の（Ｄ）参照）。このため、今度は、第２の回転ダンパー５０よりも高いダンパー力を有する第１の回転ダンパー３０のダンパー力を受けつつ第１のヒンジ本体２０が回動（枢動）する。また、このように、第２の回転ダンパー５０から第１の回転ダンパー３０に切り替わると、第１のヒンジ本体２０の第１の円弧状突部７２Ｐが連結環６０の静止状態にある第１の連結環側突部７６Ｐに向けて接近するように移動し、第１の円弧状突部７２Ｐが連結環６０の第１の連結環側突部７６Ｐ一方の縁に衝合して第１のヒンジ本体２０は１８０度回動したところで止まる。図１１（Ｃ）から（Ｅ）まで連結環６０及び第１の回転ダンパー３０の回転軸３４が静止しているのが判る。 Accordingly, when the first hinge body 20 is further rotated, the first hinge body 20 is coupled to the stationary connecting ring 60 in a non-rotating state, and therefore the first hinge body 20 is also stationary and is centered on the rotation shaft 34 of the first rotating damper 30. Thus, the case 32 of the first rotary damper 30 rotates (see FIG. 11D). Therefore, this time, the first hinge body 20 rotates (pivots) while receiving the damper force of the first rotary damper 30 having a higher damper force than the second rotary damper 50. In addition, when the second rotary damper 50 is switched to the first rotary damper 30 in this way, the first arcuate protrusion 72P of the first hinge body 20 is in the stationary state of the connecting ring 60. It moves so that it may approach toward the connection ring side protrusion 76P, and the 1st circular arc-shaped protrusion 72P collides with one edge of the 1st connection ring side protrusion 76P of the connection ring 60, and the 1st hinge The main body 20 stops when it is rotated 180 degrees. 11 (C) to 11 (E), it can be seen that the connecting ring 60 and the rotating shaft 34 of the first rotating damper 30 are stationary.
　このようにして、第１のヒンジ本体２０を第２のヒンジ本体４０に向けて枢動してこれらのヒンジ本体２０、４０に取り付けられた２つの物体（例えば、蓋と筐体）を閉じることができる。 In this way, the first hinge body 20 is pivoted toward the second hinge body 40 to close the two objects (eg, lid and housing) attached to the hinge bodies 20, 40. Can do.
　図１１（Ｅ）の状態から第１のヒンジ本体２０を第２のヒンジ本体２０に対して離れるように回動する動作は、上記動作とは逆の動作となるが、この場合には、第１及び第２の回転ダンパー３０、５０のダンパー力が働かないので、図１０で述べたのと同様に、第１と第２の回動許容手段７０、９０の正動作の回動方向での許容回動角度を復帰しながら第１と第２のヒンジ本体２０、４０の相対回動が行われる。 The operation of rotating the first hinge body 20 away from the second hinge body 20 from the state of FIG. 11 (E) is the reverse of the above-described operation. Since the damper force of the first and second rotary dampers 30 and 50 does not work, the first and second rotation permission means 70 and 90 in the rotation direction of the normal operation are the same as described in FIG. The relative rotation of the first and second hinge bodies 20 and 40 is performed while returning the allowable rotation angle.
　このようにして、第１のヒンジ本体２０と第２のヒンジ本体４０とにそれぞれ取り付けられた２つの物体は開くことができるが、この逆の動作では、回転ダンパー３０、５０は、粘性流体の抵抗が低いので、これらの物体を円滑に開くことができる。 In this way, the two objects respectively attached to the first hinge body 20 and the second hinge body 40 can be opened, but in the reverse operation, the rotary dampers 30 and 50 are made of viscous fluid. Since the resistance is low, these objects can be opened smoothly.
　図１０及び図１１の動作は、いずれかのヒンジ本体側の回転ダンパーのダンパー力が他方のヒンジ本体側の回転ダンパーのダンパー力よりも小さい場合であったが、第１と第２の回転ダンパー３０、５０が同じダンパー力を有する場合には、第１と第２のヒンジ本体２０、４０を折り畳み位置に相対回動する際に、第１と第２の回動許容手段７０、９０が同時に動作してこれらの回転ダンパー３０、５０のそれぞれの限界回動角度を越えて第１と第２の許容回動角度の和まで第１と第２のヒンジ本体２０、４０を枢動することができる。また、これらの動作説明から判るように、連結環６０は、第１と第２の回転ダンパー３０、５０をそれぞれの限界回転角度を越えて回転方向に直列に駆動するようにこれらの回転ダンパー３０、５０を接続する機能を有する。 The operation of FIGS. 10 and 11 was when the damper force of the rotary damper on one hinge body side was smaller than the damper force of the rotary damper on the other hinge body side, but the first and second rotary dampers. When 30 and 50 have the same damper force, when the first and second hinge bodies 20 and 40 are relatively rotated to the folding position, the first and second rotation permitting means 70 and 90 are simultaneously Operate to pivot the first and second hinge bodies 20, 40 beyond the respective limit pivot angles of these rotary dampers 30, 50 to the sum of the first and second permissible pivot angles. it can. Further, as can be seen from the description of these operations, the connecting ring 60 is configured so that the first and second rotary dampers 30 and 50 are driven in series in the rotational direction beyond the respective limit rotational angles. , 50 are connected.
　本発明の第２の実施の形態によるダンパーヒンジ１１０が図１２乃至図１７に示されており、第１の実施の形態によるダンパーヒンジ１０と同じ部分には同じ符号が付されている。 A damper hinge 110 according to a second embodiment of the present invention is shown in FIGS. 12 to 17, and the same reference numerals are given to the same portions as the damper hinge 10 according to the first embodiment.
　このダンパーヒンジ１１０は、第１と第２のヒンジ本体２０、４０内に跨って配置される少なくとも１つの連結ブラケット（第２の連結環）１２０と、この連結ブラケット１２０に設けられた第３の回転ダンパー１３０とを備え、連結環６０は、第３の回転ダンパー１３０の回転軸１３４と第２の回転ダンパー５０の回転軸５４とを連結している点で第１の実施の形態によるダンパーヒンジと異なる。 The damper hinge 110 includes at least one connection bracket (second connection ring) 120 disposed across the first and second hinge bodies 20 and 40 and a third bracket provided on the connection bracket 120. The damper ring according to the first embodiment in that the connecting ring 60 connects the rotating shaft 134 of the third rotating damper 130 and the rotating shaft 54 of the second rotating damper 50. And different.
