Description

本発明は、ヒンジ装置における開き位置規制構造の改良に関する。 The present invention relates to an improvement in an opening position regulating structure in a hinge device.

筺体の開口部を扉で開閉するために用いられるヒンジ装置は、筐体に取り付けられるヒンジ本体と、ソケット部を有し扉に取り付けられる取付部材と、取付部材をヒンジ本体に回動可能に連結するリンク機構と、を備えている。リンク機構は、ヒンジ本体に設けられた互いに平行な第１及び第２枢軸と、取付部材のソケット部内に設けられ第１及び第２枢軸と平行な第３及び第４枢軸と、一端部が第１枢軸を介してヒンジ本体に回動可能に連結され他端部が第３枢軸を介して取付部材に回動可能に連結された第１リンクと、一端部が第２枢軸を介してヒンジ本体に回動可能に連結され他端部が第４枢軸を介して取付部材に回動可能に連結された第２リンクと、を有している。 The hinge device used to open and close the opening of the housing with a door is a hinge body that is attached to the housing, a mounting member that has a socket and is attached to the door, and the mounting member that is rotatably connected to the hinge body. It is equipped with a link mechanism. The link mechanism includes the first and second pivots parallel to each other provided in the hinge body, the third and fourth pivots provided in the socket portion of the mounting member and parallel to the first and second pivots, and one end thereof. The first link rotatably connected to the hinge body via one pivot and the other end rotatably connected to the mounting member via the third pivot, and one end rotatably connected to the mounting member via the second pivot. It has a second link that is rotatably connected to and the other end of which is rotatably connected to the mounting member via a fourth pivot.

上記構成のヒンジ装置では、通常、扉の閉位置と開位置との間の回動角度が１００°〜１２０°程度に設定されている。しかし、扉を閉位置から例えば９０°以上回動させると、扉が壁等にぶつかるような場合には、扉の回動角度をより小さくすることが求められる。そのような場合に、扉の回動角度が９０°より小さくなるようにヒンジ装置を製造すると、ヒンジ装置の種類が増えてしまい、ヒンジ装置の製造費や管理費が嵩むという問題がある。 In the hinge device having the above configuration, the rotation angle between the closed position and the open position of the door is usually set to about 100 ° to 120 °. However, if the door is rotated by, for example, 90 ° or more from the closed position and the door hits a wall or the like, it is required to make the rotation angle of the door smaller. In such a case, if the hinge device is manufactured so that the rotation angle of the door is smaller than 90 °, the types of the hinge device increase, and there is a problem that the manufacturing cost and the management cost of the hinge device increase.

そこで、ヒンジ装置に装着して扉の回動角度を狭める規制部材が種々開発されている。下記特許文献１に記載されている規制部材は、その両端部に係合部を有し、これら係合部を取付部材のソケット内に配置された第３枢軸と第４枢軸に嵌めることにより、ヒンジ装置に装着されている。扉が開いた時に、第１リンクが規制部材に当たることにより、扉の開き位置が定められる。 Therefore, various regulatory members have been developed that are attached to a hinge device to narrow the rotation angle of the door. The regulatory member described in Patent Document 1 below has engaging portions at both ends thereof, and by fitting these engaging portions into the third and fourth pivots arranged in the socket of the mounting member. It is attached to the hinge device. When the door is opened, the opening position of the door is determined by the first link hitting the regulating member.

The engaging member 27 is rotatably supported around the support pin 26, and a torsion coil spring 28 that rotatably urges the engaging member 27 is wound around the support pin 26.

マウント部材２２の係合ピン２５がベース金具２１の係合凹部に係合し、係合部材２７の凹部２７ａがベース金具２１の係合ピンに係合することにより、ヒンジ本体１０はマウント部材２２を介してベース金具２１に着脱可能に取り付けられている。 The engagement pin 25 of the mount member 22 engages with the engagement recess of the base metal fitting 21, and the recess 27a of the engagement member 27 engages with the engagement pin of the base metal fitting 21, so that the hinge body 10 is mounted on the mount member 22. It is detachably attached to the base metal fitting 21 via.

調節機構２３は、ヒンジ本体１０を前後方向に位置調節するとともに、その前端部を左右方向（すなわち筺体２の側壁２ｂと直交する方向）に位置調節するものであるが、本発明の要旨ではないので、詳細な説明を省略する。 The adjusting mechanism 23 adjusts the position of the hinge body 10 in the front-rear direction and adjusts the position of the front end portion thereof in the left-right direction (that is, the direction orthogonal to the side wall 2b of the housing 2), but this is not the gist of the present invention. Therefore, a detailed description will be omitted.

取付部材３０は、カップ形状のソケット部３１と、ソケット部３１の開口３１ａの縁部に連なる一対の鍔部３２を有しており、扉３の側縁部近傍においてその背面（筺体２側の面）に取り付けられている。より具体的には、扉３には穴３ａが形成されており、この穴３ａにソケット部３１が収容され、一対の鍔部３２が上下に配置された状態で扉３に固定されている。 The mounting member 30 has a cup-shaped socket portion 31 and a pair of flange portions 32 connected to the edge portion of the opening 31a of the socket portion 31, and the back surface thereof (on the side of the housing 2) in the vicinity of the side edge portion of the door 3. It is attached to the surface). More specifically, a hole 3a is formed in the door 3, a socket portion 31 is housed in the hole 3a, and a pair of collar portions 32 are fixed to the door 3 in a vertically arranged state.

取付部材３０は、リンク機構４０により、図１（Ａ）に示す閉位置と図１（Ｂ）に示す開位置との間でヒンジ本体１０に回動可能に連結されている。
リンク機構４０は、ヒンジ本体１０の前端部に設けられた第１枢軸４１および第２枢軸４２と、取付部材３０のソケット部３１に設けられた第３枢軸４３および第４枢軸４４を有している。これら枢軸４１〜４４は互いに平行をなして上下方向に延びている。 The attachment member 30 is rotatably connected to the hinge body 10 between the closed position shown in FIG. 1 (A) and the open position shown in FIG. 1 (B) by a link mechanism 40.
The link mechanism 40 has a first pivot 41 and a second pivot 42 provided at the front end of the hinge body 10, and a third pivot 43 and a fourth pivot 44 provided at the socket portion 31 of the mounting member 30. There is. These Axis 41-44 are parallel to each other and extend in the vertical direction.

第１枢軸４１は、第２枢軸４２より前方において側壁２ｂから離れている。第３枢軸４３はソケット部３１の奥側に配置され、第４枢軸４４はソケット部３１の開口３１ａ寄りに配置されている。第１枢軸４１と第２枢軸４２の間隔に比べて、第３枢軸４３と第４枢軸４４の間隔は狭くなっている。本実施形態では図２に示すように、第３枢軸４３と第４枢軸４４はＵ字形の部材により一体に形成されている。 The first pivot 41 is separated from the side wall 2b in front of the second pivot 42. The third pivot 43 is arranged on the back side of the socket portion 31, and the fourth pivot 44 is arranged near the opening 31a of the socket portion 31. The distance between the third axis 43 and the fourth axis 44 is narrower than the distance between the first axis 41 and the second axis 42. In the present embodiment, as shown in FIG. 2, the third pivot 43 and the fourth pivot 44 are integrally formed by a U-shaped member.

リンク機構４０はさらに、第１リンク４５と第２リンク４６を有している。
第１リンク４５は、断面が略コ字形をなしており、主板部４５ａと、この主板部４５ａの両側縁に直角をなして連なる一対の側板部４５ｂとを有している。一対の側板部４５ｂの一端部が第１枢軸４１を介してヒンジ本体１０の前端部に回動可能に連結され、他端部が第３枢軸４３を介して取付部材３０のソケット部３１に回動可能に連結されている。 The link mechanism 40 further has a first link 45 and a second link 46.
The first link 45 has a substantially U-shaped cross section, and has a main plate portion 45a and a pair of side plate portions 45b connected at right angles to both side edges of the main plate portion 45a. One end of the pair of side plate portions 45b is rotatably connected to the front end portion of the hinge body 10 via the first pivot 41, and the other end is rotated to the socket portion 31 of the mounting member 30 via the third pivot 43. It is movably connected.

第２リンク４６は、主板部４６ａと、この主板部４６ａの一端部の両側に直角をなして連なる一対の側板部４６ｂを有している。一対の側板部４６ｂが第２枢軸４２を介してヒンジ本体１０の前端部に回動可能に連結されている。主板部４６ａの他端部は上記一端部に比べて幅が狭く、丸められて挿通部４６ｃとなっている。この挿通部４６ｃに第４枢軸４４が挿通されることにより、第２リンク４６は取付部材３０のソケット部３１に回動可能に連結されている。
第１枢軸４１と第２枢軸４２の間隔および第３枢軸４３と第４枢軸４４の間隔は、第１枢軸４１と第３枢軸４３の間隔および第２枢軸４２と第４枢軸４４の間隔より狭い。 The second link 46 has a main plate portion 46a and a pair of side plate portions 46b that are connected at right angles to both sides of one end portion of the main plate portion 46a. The pair of side plate portions 46b are rotatably connected to the front end portion of the hinge body 10 via the second pivot 42. The other end of the main plate 46a is narrower than the one end and is rounded to form the insertion portion 46c. By inserting the fourth pivot 44 through the insertion portion 46c, the second link 46 is rotatably connected to the socket portion 31 of the mounting member 30.
The distance between the first axis 41 and the second axis 42 and the distance between the third axis 43 and the fourth axis 44 are narrower than the distance between the first axis 41 and the third axis 43 and the distance between the second axis 42 and the fourth axis 44. ..

扉３および取付部材３０が図１（Ａ）に示す閉位置にある時、第１リンク４５がソケット部３１の奥側に配置され第２リンク４６がソケット部３１の開口３１ａ側に配置される。取付部材３０の図１（Ａ）に示す閉位置は、扉３が筐体２の前端面に突き当たることによって定められているが、ヒンジ装置１単体の状態では、取付部材３０は、図１（Ａ）閉位置よりもさらに閉方向へ所定の角度（例えば５°程度）だけ回動可能である。ヒンジ装置１単体での取付部材３０の閉位置は、第１リンク４５が取付部材３０のソケット部３１の底部に突き当たることによって定められる。 When the door 3 and the mounting member 30 are in the closed positions shown in FIG. 1A, the first link 45 is arranged on the back side of the socket portion 31 and the second link 46 is arranged on the opening 31a side of the socket portion 31. .. The closed position shown in FIG. 1A of the mounting member 30 is determined by the door 3 abutting against the front end surface of the housing 2, but in the state of the hinge device 1 alone, the mounting member 30 is shown in FIG. A) It is possible to rotate a predetermined angle (for example, about 5 °) in the closing direction from the closed position. The closed position of the mounting member 30 of the hinge device 1 alone is determined by the first link 45 abutting against the bottom of the socket portion 31 of the mounting member 30.

扉３および取付部材３０が開く際に、扉３は回動しながら前方へ変位する。第３枢軸４３は、常に第４枢軸４４より前方に位置しており、第４枢軸４４を中心に図１において反時計回り方向に回る。扉３および取付部材３０が図１（Ｂ）に示す開位置にある時、第１リンク４５がソケット部３１の開口３１ａに臨み、第２リンク４６が開口３１ａの反対側に臨む。 When the door 3 and the mounting member 30 are opened, the door 3 is displaced forward while rotating. The third pivot 43 is always located in front of the fourth pivot 44 and rotates counterclockwise in FIG. 1 with respect to the fourth pivot 44. When the door 3 and the mounting member 30 are in the open positions shown in FIG. 1 (B), the first link 45 faces the opening 31a of the socket portion 31, and the second link 46 faces the opposite side of the opening 31a.

扉３および取付部材３０は、後述する規制部材５０が装着されていない場合には、図１（Ｂ）に示す開位置よりさらに開き方向に開くことができる。その場合の開き角度は、１００〜１２０°が一般的である。この場合の扉３の開位置（取付部材３０の開位置）は、第２リンク４６が取付部材３０のソケット部３１の開口３１ａの縁部に当たることにより定められる。 The door 3 and the mounting member 30 can be opened in the opening direction further from the opening position shown in FIG. 1 (B) when the regulation member 50 described later is not mounted. In that case, the opening angle is generally 100 to 120 °. The open position of the door 3 (open position of the mounting member 30) in this case is determined by the second link 46 hitting the edge of the opening 31a of the socket portion 31 of the mounting member 30.

第１枢軸４１には捩りコイルばね４８が巻かれている。捩りコイルばね４８の一端部は、ヒンジ本体１０の主板部１１の前端部に当たり、他端部は、第２リンク４６の一対の側板部４６ｂに架け渡された受圧ピン４９に当たっている。その結果、取付部材３０がリンク機構４０を介して捩りコイルばね４８により回動付勢されている。取付部材３０は、閉位置と所定の中間位置との間に位置している時には閉じ方向に回動付勢され、中間位置と開位置との間に位置しているときには、開き方向に回動付勢される。 A torsion coil spring 48 is wound around the first pivot 41. One end of the torsion coil spring 48 hits the front end of the main plate 11 of the hinge body 10, and the other end hits the pressure receiving pins 49 spanning the pair of side plate 46b of the second link 46. As a result, the mounting member 30 is rotationally urged by the torsion coil spring 48 via the link mechanism 40. The mounting member 30 is urged to rotate in the closing direction when it is located between the closed position and a predetermined intermediate position, and rotates in the opening direction when it is located between the intermediate position and the open position. Be urged.

次に、本発明の特徴部をなす規制部材５０について説明する。規制部材５０は、扉３の回動角度範囲を、規制部材５０が装着されない場合の１００〜１２０°から例えば８５°に狭めるために用いられる。
ヒンジ装置１の殆どの構成部材は金属製であるが、規制部材５０は硬質の樹脂により成形されている。 Next, the regulating member 50 which is a feature of the present invention will be described. The regulating member 50 is used to narrow the rotation angle range of the door 3 from 100 to 120 ° when the regulating member 50 is not mounted to, for example, 85 °.
Most of the constituent members of the hinge device 1 are made of metal, but the regulating member 50 is made of a hard resin.

図３、図４に示すように、規制部材５０は、第４枢軸４４に沿って延びる主部５１と、主部５１の両端部に形成され主部５１より断面積の大きな（厚肉の）一対の荷重受部５２とを一体に有している。一対の荷重受部５２は、主部５１から同方向に突出しており、一対の荷重受部５２間には空隙５６が形成されている。 As shown in FIGS. 3 and 4, the regulating member 50 has a main portion 51 extending along the fourth pivot 44 and a main portion 51 formed at both ends of the main portion 51 and having a larger cross-sectional area (thick wall) than the main portion 51. It integrally has a pair of load receiving portions 52. The pair of load receiving portions 52 project in the same direction from the main portion 51, and a gap 56 is formed between the pair of load receiving portions 52.

各係合部５５は、内周が１８０°を越える円筒面をなす収容空間５５ａと、この収容空間５５ａに連なる開放部５５ｂとを有している。収容空間５５ａの内径は第４枢軸４４と実質的に同径をなし、開放部５５ｂの幅は、第４枢軸４４の径より狭くなっている。
荷重受部５２には、第１リンク４５との干渉を避けるための凹曲面をなす逃げ面５２ａが形成されている。 Each engaging portion 55 has an accommodating space 55a having an inner circumference of more than 180 ° and forming a cylindrical surface, and an open portion 55b connected to the accommodating space 55a. The inner diameter of the accommodation space 55a is substantially the same as the diameter of the fourth pivot 44, and the width of the open portion 55b is narrower than the diameter of the fourth pivot 44.
The load receiving portion 52 is formed with a relief surface 52a having a concave curved surface for avoiding interference with the first link 45.

上記規制部材５０は次のようにしてヒンジ装置１の第４枢軸４４に装着される。なお、規制部材５０は、ヒンジ装置１単体の状態で装着してもよいし、扉３にヒンジ装置１（ベース金具２１を除く）を取り付けた状態で装着してもよい。 The regulation member 50 is attached to the fourth pivot 44 of the hinge device 1 as follows. The restricting member 50 may be mounted with the hinge device 1 alone, or with the hinge device 1 (excluding the base metal fitting 21) attached to the door 3.

図５（Ａ）、図６（Ａ）に示すように、取付部材３０を閉じ位置にして、ソケット部３１の開口３１ａの第４枢軸４４側を開放状態にする。規制部材５０の主部５１を指でつまみ、一対の係合部５５の開放部５５ｂを第４枢軸４４に向け、規制部材５０を第４枢軸４４に近づける。 As shown in FIGS. 5A and 6A, the mounting member 30 is set to the closed position, and the fourth pivot 44 side of the opening 31a of the socket portion 31 is opened. The main portion 51 of the regulating member 50 is pinched with fingers, the open portion 55b of the pair of engaging portions 55 is directed toward the fourth pivot 44, and the regulating member 50 is brought closer to the fourth pivot 44.

次に、図５（Ｂ）に示すように、規制部材５０の一対の係合部５５の開放部５５ｂを第４枢軸４４にあてがい、規制部材５０を押し込むことにより、図５（Ｃ）に示すように、係合部５５の収容空間５５ａに第４枢軸４４を嵌め込む。開放部５５ｂの幅が第４枢軸４４の径より小さいので、開放部５５ｂは第４枢軸４４の通過の際に係合部５５の弾性変形を伴って広げられ、第４枢軸４４が収容空間５５ａに嵌った時に、係合部５５の弾性復帰を伴って元の幅に戻る。 Next, as shown in FIG. 5 (B), the open portion 55b of the pair of engaging portions 55 of the regulating member 50 is applied to the fourth pivot 44, and the regulating member 50 is pushed in to be shown in FIG. 5 (C). As described above, the fourth pivot 44 is fitted into the accommodation space 55a of the engaging portion 55. Since the width of the opening portion 55b is smaller than the diameter of the fourth pivot 44, the opening portion 55b is expanded with elastic deformation of the engaging portion 55 when passing through the fourth pivot 44, and the fourth pivot 44 is accommodated in the accommodation space 55a. When fitted to, the width returns to the original width with the elastic return of the engaging portion 55.

上記一対の係合部５５が第４枢軸４４に係合される際、規制部材５０の空隙５６に第２リンク４６の挿通部４６ｃが入り込む。換言すれば、一対の係合部５５は、第２リンク４６の挿通部４６ｃを挟むようにして第４枢軸４４に係合される。このような構造を採用することにより、第２リンク４６の端部に切欠を形成せずに済み、第２リンク４６の強度を保つことができる。 When the pair of engaging portions 55 are engaged with the fourth pivot 44, the insertion portion 46c of the second link 46 enters the gap 56 of the regulating member 50. In other words, the pair of engaging portions 55 are engaged with the fourth pivot 44 so as to sandwich the insertion portion 46c of the second link 46. By adopting such a structure, it is not necessary to form a notch at the end of the second link 46, and the strength of the second link 46 can be maintained.

最後に図５（Ｄ）、図６（Ｂ）に示すように規制部材５０を回して主部５１をソケット部３１内に収容することにより、装着工程が完了する。 Finally, as shown in FIGS. 5 (D) and 6 (B), the regulating member 50 is turned to accommodate the main portion 51 in the socket portion 31, and the mounting process is completed.

上記規制部材５０の装着は、下記の理由により、楽に行なうことができる。
第１に、規制部材５０の係合部５５が第４枢軸４４に係合される際、主部５１がソケット部３１から突出しており、装着が完了するまで主部５１を指でつまむことができる。
第２に、第４枢軸４４がソケット部３１において開口３１ａ寄りに配置されている。
第３に、主部５１は拘束されず自由に回動可能であり、係合部５５を第４枢軸４４に係合するだけで、規制部材５０がヒンジ装置１に装着される。 The regulation member 50 can be easily attached for the following reasons.
First, when the engaging portion 55 of the regulating member 50 is engaged with the fourth pivot 44, the main portion 51 protrudes from the socket portion 31, and the main portion 51 can be pinched with fingers until the mounting is completed. it can.
Second, the fourth pivot 44 is arranged closer to the opening 31a in the socket portion 31.
Third, the main portion 51 is not restrained and can rotate freely, and the regulating member 50 is attached to the hinge device 1 simply by engaging the engaging portion 55 with the fourth pivot 44.

本実施形態では、規制部材５０の収容空間５５ａの内周が１８０°を越える円筒面からなり、開放部５５ｂの幅が第４枢軸４４の径より狭いため、扉３および取付部材３０の開閉を繰り返しても、規制部材５０は第４枢軸４４から脱落せず、確実に装着状態を維持することができる。 In the present embodiment, the inner circumference of the accommodating space 55a of the regulating member 50 is formed of a cylindrical surface exceeding 180 °, and the width of the opening portion 55b is narrower than the diameter of the fourth pivot 44, so that the door 3 and the mounting member 30 are opened and closed. Even if it is repeated, the regulating member 50 does not fall off from the fourth pivot 44, and the mounted state can be reliably maintained.

図１（Ａ）、図７（Ａ）に示すように、扉３および取付部材３０が閉位置にある時、規制部材５０は第１リンク４５と筺体２の前端面との間に配置されていて、ソケット部３１内に収容されている。この時、荷重受部５２の逃げ面５２ａに第１リンク４５の側板部４５ｂの円弧面をなす端部が配置されている。 As shown in FIGS. 1 (A) and 7 (A), when the door 3 and the mounting member 30 are in the closed position, the regulating member 50 is arranged between the first link 45 and the front end surface of the housing 2. It is housed in the socket portion 31. At this time, an end portion forming an arc surface of the side plate portion 45b of the first link 45 is arranged on the escape surface 52a of the load receiving portion 52.

図１（Ｂ）、図７（Ｂ）に示すように、扉３および取付部材３０が回動すると、規制部材５０は第２リンク４６に押され、ソケット部３１の開口３１ａの縁部に向かって回動する。さらに扉３および取付部材３０が回動して回動角度が例えば８５°に達すると、規制部材５０に第１リンク４５が当たり、第１リンク４５の回動が阻止されるため、取付部材３０の開位置、ひいては扉３の開位置が定められる。 As shown in FIGS. 1B and 7B, when the door 3 and the mounting member 30 rotate, the regulating member 50 is pushed by the second link 46 toward the edge of the opening 31a of the socket portion 31. And rotate. Further, when the door 3 and the mounting member 30 rotate and the rotation angle reaches, for example, 85 °, the first link 45 hits the regulating member 50 and the rotation of the first link 45 is prevented, so that the mounting member 30 The open position of the door 3 and the open position of the door 3 are determined.

より具体的に説明すると、上記開位置において、第１リンク４５の一対の側板部４５ｂが第４枢軸４４の近傍で一対の荷重受部５２に当たり、これら一対の荷重受部５２が、第１リンク４５の一対の側板部４５ｂと第４枢軸４４との間に挟まれる。
また、規制部材５０の一対の荷重受部５２が第１リンク４５の一対の側板部４５ｂとソケット部３１の開口３１ａの縁部との間に狭まれる。
上記一対の荷重受部５２は、第４枢軸４４と開口３１ａの縁部のいずれか一方と、一対の側板部４５ｂとで挟まれることにより、取付部材３０の回動を規制してもよい。 More specifically, at the above-mentioned open position, the pair of side plate portions 45b of the first link 45 hit the pair of load receiving portions 52 in the vicinity of the fourth pivot 44, and these pair of load receiving portions 52 are the first link. It is sandwiched between a pair of side plate portions 45b of 45 and a fourth pivot 44.
Further, the pair of load receiving portions 52 of the regulating member 50 are narrowed between the pair of side plate portions 45b of the first link 45 and the edge portion of the opening 31a of the socket portion 31.
The pair of load receiving portions 52 may be sandwiched between either one of the fourth pivot 44 and the edge portion of the opening 31a and the pair of side plate portions 45b to restrict the rotation of the mounting member 30.

上記のように規制部材の一対の荷重受部５２が第１リンク４５の一対の側板部４５ｂを介して取付部材３０および扉３の開き動作時の荷重をバランス良く受け止めることができ、取付部材３０および扉３の回動規制を安定して行なうことができる。 As described above, the pair of load receiving portions 52 of the regulating member can receive the load during the opening operation of the mounting member 30 and the door 3 in a well-balanced manner via the pair of side plate portions 45b of the first link 45, and the mounting member 30 can be received. And the rotation regulation of the door 3 can be stably performed.

扉３および取付部材３０が開位置から閉位置に戻る時には、規制部材５０の主部５１が筺体２の前端面に押されるため、規制部材５０は回動してソケット部３１内に収容される。規制部材５０は回動可能であるので、扉３および取付部材３０が回動する際の抵抗にはならない。 When the door 3 and the mounting member 30 return from the open position to the closed position, the main portion 51 of the restricting member 50 is pushed by the front end surface of the housing 2, so that the restricting member 50 rotates and is housed in the socket portion 31. .. Since the regulating member 50 is rotatable, it does not become a resistance when the door 3 and the mounting member 30 rotate.

次に、図８を参照しながら、本発明の第２実施形態に係るヒンジ装置について説明する。第２実施形態では、第１実施形態と細部が異なるだけであるので、図において各構成部材に同番号を付してその詳細な説明を省略する。
第２実施形態では、第１リンク４５の代わりに第２リンク４６が規制部材５０に当たることにより、第２リンク４６の回動が規制され、扉３および取付部材３０の開き位置が定められる。より具体的には上記開き位置において、規制部材５０の一対の荷重受部５２が第２リンク４６の主板部４６ａとソケット３１の開口３１ａの縁部とで挟まれる。 Next, the hinge device according to the second embodiment of the present invention will be described with reference to FIG. In the second embodiment, only the details are different from those in the first embodiment. Therefore, the components are numbered the same in the drawings, and detailed description thereof will be omitted.
In the second embodiment, the second link 46 hits the regulating member 50 instead of the first link 45, so that the rotation of the second link 46 is restricted and the opening positions of the door 3 and the mounting member 30 are determined. More specifically, at the opening position, the pair of load receiving portions 52 of the regulating member 50 are sandwiched between the main plate portion 46a of the second link 46 and the edge portion of the opening 31a of the socket 31.

次に、図９〜図１３を参照しながら、本発明の第３実施形態に係るヒンジ装置について説明する。本実施形態では、第１実施形態と異なる樹脂製の規制部材６０を用いるが、ヒンジ装置の他の構成は第１実施形態と同じであるので、同一符号を付してその説明を省略する。 Next, the hinge device according to the third embodiment of the present invention will be described with reference to FIGS. 9 to 13. In this embodiment, a resin regulating member 60 different from that of the first embodiment is used, but since the other configurations of the hinge device are the same as those of the first embodiment, the same reference numerals are given and the description thereof will be omitted.

図９、図１０に示すように、本実施形態の規制部材６０は、第２枢軸４２（他方の枢軸）と第４枢軸４４（一方の枢軸）との間を延びるとともにく字形に折れ曲った主部６１と、主部６１の一端部に形成され第４枢軸４４に沿って延びる架橋部６２と、架橋部６２の両端部に形成され架橋部６２より厚肉をなす一対の荷重受部６３とを一体に有している。
主部６１と架橋部６２は略直交しており、架橋部６２の中央に主部６１が連なっている。一対の荷重受部６３は、架橋部６２から同方向に突出しており、一対の荷重受部６３間には空隙６６が形成されている。 As shown in FIGS. 9 and 10, the regulating member 60 of the present embodiment extends between the second pivot 42 (the other pivot) and the fourth pivot 44 (one pivot) and is bent in a dogleg shape. A main portion 61, a bridge portion 62 formed at one end of the main portion 61 and extending along the fourth pivot 44, and a pair of load receiving portions 63 formed at both ends of the bridge portion 62 and thicker than the bridge portion 62. And have one.
The main portion 61 and the bridge portion 62 are substantially orthogonal to each other, and the main portion 61 is connected to the center of the bridge portion 62. The pair of load receiving portions 63 project in the same direction from the cross-linked portion 62, and a gap 66 is formed between the pair of load receiving portions 63.

一対の荷重受部６３の先端部には、それぞれ第１係合部６５（一方の係合部）が形成されている。第１係合部６５は、第１実施形態の係合部５５と同様の形状をなし、内周が１８０°を越える円筒面をなす収容空間６５ａと、第４枢軸４４の径より小さい幅の開放部６５ｂを有している。 A first engaging portion 65 (one engaging portion) is formed at each of the tip portions of the pair of load receiving portions 63. The first engaging portion 65 has the same shape as the engaging portion 55 of the first embodiment, and has a storage space 65a having a cylindrical surface whose inner circumference exceeds 180 ° and a width smaller than the diameter of the fourth pivot 44. It has an open portion 65b.

主部６１の他端部には、第２係合部６８（他方の係合部）が形成されている。詳述すると、主部６１には、主部６１の面と直交するリブ６１ａが形成されている。第２係合部６８は、このリブ６１ａの先端に形成された係合突起６８ａと、この係合突起６８ａに隣接する係合面６８ｂと、を有している。係合面６８ｂにおいて係合突起６８ａの近傍部は湾曲面をなしている。
さらに本実施形態の第２係合部６８は、係合突起６８ａと係合面６８ｂを介して対向する二股の補助係合突起６８ｃとを有している。これら係合突起６８ａ，係合面６８ｂ、補助係合突起６８ｃにより、大きく開放された収容空間６８ｘが形成されている。 A second engaging portion 68 (the other engaging portion) is formed at the other end of the main portion 61. More specifically, the main portion 61 is formed with ribs 61a orthogonal to the plane of the main portion 61. The second engaging portion 68 has an engaging projection 68a formed at the tip of the rib 61a and an engaging surface 68b adjacent to the engaging projection 68a. On the engaging surface 68b, a portion near the engaging projection 68a forms a curved surface.
Further, the second engaging portion 68 of the present embodiment has an engaging protrusion 68a and a bifurcated auxiliary engaging protrusion 68c facing each other via the engaging surface 68b. The engaging projection 68a, the engaging surface 68b, and the auxiliary engaging projection 68c form a widely open accommodation space 68x.

上記規制部材５０はヒンジ装置１の第４枢軸４４と第２枢軸４２に装着される。以下に、その装着工程を説明する。
図１１（Ａ）に示すように、取付部材３０を閉位置にした状態で、規制部材６０の主部６１を指でつまみ、一対の第１係合部６５の開放部６５ｂを第４枢軸４４に向け、規制部材６０を第４枢軸４４に近づける。 The regulating member 50 is attached to the fourth pivot 44 and the second pivot 42 of the hinge device 1. The mounting process will be described below.
As shown in FIG. 11A, with the mounting member 30 in the closed position, the main portion 61 of the regulating member 60 is pinched with fingers, and the open portion 65b of the pair of first engaging portions 65 is held by the fourth pivot 44. The regulating member 60 is brought closer to the fourth pivot 44.

次に、図１１（Ｂ）に示すように、規制部材６０の一対の第１係合部６５の開放部６５ｂを第４枢軸４４にあてがい、規制部材６０を押し込むことにより、第１係合部６５の収容空間６５ａに第４枢軸４４を嵌め込む。開放部６５ｂの幅が第４枢軸４４の径より小さいので、開放部６５ｂは第４枢軸４４の通過の際に第１係合部６５の弾性変形を伴って広げられ、第４枢軸４４が収容空間６５ａに嵌った時に、第１係合部６５の弾性復帰を伴って元の幅に戻る。 Next, as shown in FIG. 11B, the opening portion 65b of the pair of first engaging portions 65 of the regulating member 60 is applied to the fourth pivot 44, and the regulating member 60 is pushed in to push the first engaging portion. The fourth pivot 44 is fitted into the accommodation space 65a of 65. Since the width of the opening portion 65b is smaller than the diameter of the fourth pivot 44, the opening portion 65b is expanded with elastic deformation of the first engaging portion 65 when passing through the fourth pivot 44, and the fourth pivot 44 is accommodated. When fitted in the space 65a, the width returns to the original width with the elastic return of the first engaging portion 65.

上記一対の係合部６５が第４枢軸４４に係合される際、規制部材６０の空隙６６に第２リンク４６の挿通部４６ｃが入り込む。換言すれば、一対の係合部６５は、第２リンク４６の挿通部４６ｃを挟むようにして第４枢軸４４に係合される。 When the pair of engaging portions 65 are engaged with the fourth pivot 44, the insertion portion 46c of the second link 46 enters the gap 66 of the regulating member 60. In other words, the pair of engaging portions 65 are engaged with the fourth pivot 44 so as to sandwich the insertion portion 46c of the second link 46.

次に、規制部材６０を、第４枢軸４４を中心にして回すことにより、図１１（Ｃ）、図１２に示すように第２係合部６８を第２枢軸４２に係合する。詳述すると、第２係合部６８の係合突起６８ａの回動軌跡上に、第２枢軸４２の一部が位置している（回動軌跡と干渉している）ため、規制部材６０を回すと係合突起６８ａが第２枢軸４２に当たる。この状態で、規制部材６０の主部６１または架橋部６２を押し込むと、係合突起６８ａが主部６１の弾性変形を伴って第２枢軸４２を乗り越え、第２枢軸４２が第２係合部６８の収容空間６８ｘに収容される。この状態で、第２係合部６８の係合突起６８ａが第２枢軸４２に係止されるので、規制部材６０は、ヒンジ本体１０から離れる方向の回動を禁じられ、補助係合突起６８ｃが第２枢軸４２に係止されるので、ヒンジ本体１０の主板部１１に向かう回動を禁じられる。また係合面６８ｂが第２枢軸４２の外周に接しているので、安定した係合状態が得られる。 Next, by turning the regulation member 60 around the fourth pivot 44, the second engaging portion 68 is engaged with the second pivot 42 as shown in FIGS. 11C and 12. More specifically, since a part of the second pivot 42 is located (interferes with the rotation locus) on the rotation locus of the engagement protrusion 68a of the second engagement portion 68, the regulating member 60 is used. When turned, the engaging protrusion 68a hits the second pivot 42. In this state, when the main portion 61 or the cross-linked portion 62 of the regulating member 60 is pushed in, the engaging projection 68a gets over the second pivot 42 with elastic deformation of the main portion 61, and the second pivot 42 becomes the second engaging portion. It is accommodated in 68 accommodation spaces 68x. In this state, since the engaging projection 68a of the second engaging portion 68 is locked to the second pivot 42, the restricting member 60 is prohibited from rotating in the direction away from the hinge main body 10, and the auxiliary engaging projection 68c is prohibited. Is locked to the second pivot 42, so that the hinge body 10 is prohibited from rotating toward the main plate portion 11. Further, since the engaging surface 68b is in contact with the outer periphery of the second pivot 42, a stable engaging state can be obtained.

上記規制部材６０の装着工程において、第１係合部６５を第４枢軸４４に係合する際に主部６１がソケット部３１から突出しており、指でつまむことができること、および第４枢軸４４がソケット部３１において開口３１ａ寄りに配置されていること、規制部材６０を回してソケット部３１の外に位置する第２枢軸４２に係合することにより、作業性良く規制部材６０の装着を行うことができる。 In the mounting process of the regulation member 60, when the first engaging portion 65 is engaged with the fourth pivot 44, the main portion 61 protrudes from the socket portion 31 and can be pinched by fingers, and the fourth pivot 44. Is arranged closer to the opening 31a in the socket portion 31, and the regulating member 60 is mounted by turning the regulating member 60 and engaging with the second pivot 42 located outside the socket portion 31 with good workability. be able to.

本実施形態の規制部材６０は、第４枢軸４４のみならず第２枢軸４２にも係合されているので、扉３および取付部材３０の開閉に伴い、第２リンク４６と一緒に回動する。
図１３（Ａ）に示すように、規制部材６０の主部６１はく字形に折れ曲がっているので、扉３および取付部材３０が閉位置にある時、主部６１において筺体２の側壁２ｂに対向する部位は、ソケット部３１内に収容されており側壁２ｂと干渉しない。 Since the regulation member 60 of the present embodiment is engaged not only with the fourth pivot 44 but also with the second pivot 42, it rotates together with the second link 46 as the door 3 and the mounting member 30 are opened and closed. ..
As shown in FIG. 13A, since the main portion 61 of the regulating member 60 is bent in a dogleg shape, when the door 3 and the mounting member 30 are in the closed position, the main portion 61 faces the side wall 2b of the housing 2. The portion to be used is housed in the socket portion 31 and does not interfere with the side wall 2b.

図１３（Ｂ）に示すように、扉３および取付部材３０が開位置にある時、第１リンク４５の一対の側板部４５ｂが規制部材６０の一対の荷重受部６３に当たり、一対の側板部４５ｂと第４枢軸４４との間で一対の荷重受部６３が挟まれる。 As shown in FIG. 13B, when the door 3 and the mounting member 30 are in the open position, the pair of side plate portions 45b of the first link 45 hit the pair of load receiving portions 63 of the regulation member 60, and the pair of side plate portions A pair of load receiving portions 63 are sandwiched between 45b and the fourth pivot 44.

容易に理解できるので図示しないが、第３実施形態でも第１実施形態と同様に、規制部材６０が、第１リンク４５または第２リンク４６とソケット部３１の開口３１ａの縁部とで挟まれることにより、扉３および取付部材３０の開位置が定められるようにしてもよい。 Although not shown because it is easy to understand, in the third embodiment as in the first embodiment, the regulating member 60 is sandwiched between the first link 45 or the second link 46 and the edge of the opening 31a of the socket portion 31. Thereby, the open positions of the door 3 and the mounting member 30 may be determined.

次に、図１４〜図１８を参照しながら、本発明の第４実施形態に係るヒンジ装置について説明する。本実施形態では、樹脂製の規制部材７０以外のヒンジ装置の構成は第１実施形態と同じであるので、同一符号を付してその説明を省略する。 Next, the hinge device according to the fourth embodiment of the present invention will be described with reference to FIGS. 14 to 18. In the present embodiment, the configuration of the hinge device other than the resin regulating member 70 is the same as that in the first embodiment, so the same reference numerals are given and the description thereof will be omitted.

図１４、図１５に示すように、規制部材７０は、第２枢軸４２（一方の枢軸）と第４枢軸４４（他方の枢軸）間を延びるとともに湾曲形状をなす主部７１と、中央が主部７１の一端部に連なるとともに第４枢軸４４に沿って延びる架橋部７２と、架橋部７２の両端部に形成された架橋部７２より厚肉の一対の荷重受部７３と、を一体に有している。一対の荷重受部７３には、それぞれ第１係合部７５（他方の係合部）が形成され、主部７１の他端部には第２係合部７８（一方の係合部）が形成されている。
上述の点で、第４実施形態の規制部材７０は、第３実施形態の規制部材６０と似ている。しかし、本実施形態の第１係合部７５と第２係合部７８の形状および役割は、第３実施形態の規制部材６０と異なっている。以下、詳述する。 As shown in FIGS. 14 and 15, the regulating member 70 has a main portion 71 extending between the second pivot 42 (one pivot) and the fourth pivot 44 (the other pivot) and having a curved shape, and the center is the main portion. A bridge portion 72 that is connected to one end of the portion 71 and extends along the fourth pivot 44, and a pair of load receiving portions 73 that are thicker than the bridge portions 72 formed at both ends of the bridge portion 72 are integrally provided. doing. A first engaging portion 75 (the other engaging portion) is formed on each of the pair of load receiving portions 73, and a second engaging portion 78 (one engaging portion) is formed on the other end of the main portion 71. It is formed.
In the above points, the regulatory member 70 of the fourth embodiment is similar to the regulatory member 60 of the third embodiment. However, the shapes and roles of the first engaging portion 75 and the second engaging portion 78 of the present embodiment are different from those of the regulating member 60 of the third embodiment. The details will be described below.

第２係合部７８は、主部７１から延びる２つの第１片７８ｘと１つの第２片７８ｙにより構成されている。第１片７８ｘと第２片７８ｙは主部７１の延び方向と交叉する方向に対向しており、第１片７８ｘと第２片７８ｙ間に収容空間７８ａが形成されるとともに、この収容空間７８ａに連なる開放部７８ｂが形成されている。この開放部７８ｂは主部７１の反対側に位置しており、その幅は第２枢軸４２の径以上である。 The second engaging portion 78 is composed of two first pieces 78x extending from the main portion 71 and one second piece 78y. The first piece 78x and the second piece 78y face each other in a direction intersecting the extending direction of the main portion 71, and an accommodation space 78a is formed between the first piece 78x and the second piece 78y, and the accommodation space 78a is formed. An open portion 78b connected to the above is formed. The open portion 78b is located on the opposite side of the main portion 71, and its width is equal to or larger than the diameter of the second pivot 42.

第１係合部７５は、主部７１の反対側に突出する係合突起７５ａと、この係合突起７５ａに隣接する係合面７５ｂとを有している。この係合面７５ｂは係合突起７５ａの近傍部で湾曲している。 The first engaging portion 75 has an engaging protrusion 75a projecting to the opposite side of the main portion 71, and an engaging surface 75b adjacent to the engaging protrusion 75a. The engaging surface 75b is curved in the vicinity of the engaging projection 75a.

上記架橋部７２において上記係合突起７５ａの反対側の面には、一対の荷重受部７３を含む架橋部７２の全長にわたって、溝７９が形成されている。この溝７９は、後述するようにソケット部３１の開口３１ａの縁部が当たる当接面７９ａと、この開口３１ａの縁部に沿う湾曲した逃げ面７９ｂとを有している。 A groove 79 is formed on the surface of the bridged portion 72 on the opposite side of the engaging projection 75a over the entire length of the bridged portion 72 including the pair of load receiving portions 73. As will be described later, the groove 79 has a contact surface 79a on which the edge of the opening 31a of the socket portion 31 abuts, and a curved escape surface 79b along the edge of the opening 31a.

次に、上記構成をなす規制部材７０のヒンジ装置１への装着工程について説明する。図１６（Ａ）、（Ｂ）に示すように、最初に、規制部材７０の主部７１を指でつまみ、第２係合部７８を第２枢軸４２に係合する。すなわち、第２枢軸４２の径方向から規制部材７０を近づけて、開放部７８ｂを介して収容空間７８ａに第２枢軸４２を収容する。 Next, a step of attaching the restricting member 70 having the above configuration to the hinge device 1 will be described. As shown in FIGS. 16A and 16B, first, the main portion 71 of the regulating member 70 is pinched with fingers, and the second engaging portion 78 is engaged with the second pivot 42. That is, the regulation member 70 is brought closer from the radial direction of the second pivot 42, and the second pivot 42 is accommodated in the accommodation space 78a via the open portion 78b.

次に、図１６（Ｂ）に矢印で示すように規制部材７０を、第２枢軸４２を中心としてソケット部３１に向けて回動させると、図１６（Ｃ）に示すように、第１係合部７５の係合突起７５ａが第４枢軸４４に当たる。規制部材７０が、第２枢軸４２を中心に回動する際に、係合突起７５ａの回動軌跡上に第４枢軸４４の一部が位置する（回動軌跡と第４枢軸４４が干渉する）からである。 Next, when the regulating member 70 is rotated toward the socket portion 31 about the second pivot 42 as shown by the arrow in FIG. 16 (B), the first engagement member 70 is shown in FIG. 16 (C). The engaging projection 75a of the joint portion 75 hits the fourth pivot 44. When the regulating member 70 rotates about the second pivot 42, a part of the fourth pivot 44 is located on the rotation locus of the engaging projection 75a (the rotation locus and the fourth pivot 44 interfere with each other). ).

図１６（Ｃ）に示すように係合突起７５ａが第４枢軸４４に当たった状態で、主部７１又は架橋部７２を押すと、主部７１の弾性変形を伴って係合突起７５ａが第４枢軸４４を超え、図１６（Ｄ）に示すように第４枢軸４４の裏側（ソケット部３１の奥側に至り、係合面７５ａが第４枢軸４４の外周に接した状態になる。 As shown in FIG. 16C, when the main portion 71 or the cross-linked portion 72 is pushed while the engaging protrusion 75a is in contact with the fourth pivot 44, the engaging protrusion 75a is brought into the position with elastic deformation of the main portion 71. Beyond the four pivots 44, as shown in FIG. 16D, the back side of the fourth pivot 44 (reaching the inner side of the socket portion 31 and the engaging surface 75a is in contact with the outer periphery of the fourth pivot 44).

図１６（Ｄ）に示す規制部材７０の装着状態では、係合突起７５ａが第４枢軸４４に係止されるため、規制部材７０は第２枢軸４２を中心としてソケット部３１から離れる方向に回動するのを禁じられ、ひいては第１係合部７５が第４枢軸４４から脱落するのを禁じられている。また、第１係合部７５の係合面７５ｂが第４枢軸４４の外周に接するので、第４枢軸４４への係合状態を安定して維持することができる。
なお、本実施形態では、第１係合部７５は規制部材７０がソケット部３１の奥に向かて回動するのを禁じないが、この方向の回動は第２リンク４６の主板部４６ａにより規制されている。本実施形態において規制部材７０は、後述する取付部材３０の回動の過程で、第２リンク４２に対して数度の回動のみが許容される。 In the mounted state of the regulating member 70 shown in FIG. 16 (D), the engaging projection 75a is locked to the fourth pivot 44, so that the regulating member 70 rotates in a direction away from the socket portion 31 around the second pivot 42. It is forbidden to move, and thus the first engaging portion 75 is forbidden to fall off the fourth Axis 44. Further, since the engaging surface 75b of the first engaging portion 75 is in contact with the outer circumference of the fourth pivot 44, the engaged state with the fourth pivot 44 can be stably maintained.
In the present embodiment, the first engaging portion 75 does not prohibit the regulating member 70 from rotating toward the back of the socket portion 31, but the rotation in this direction is the main plate portion 46a of the second link 46. Is regulated by. In the present embodiment, the regulating member 70 is allowed to rotate only a few degrees with respect to the second link 42 in the process of rotating the mounting member 30, which will be described later.

上記規制部材７０の装着工程において、主部７１を指でつまんで、第２係合部７８をソケット部３１の外に位置する第２枢軸４２に係合すること、規制部材７０を回して第１係合部７５を第４枢軸４４に係合すること、この第１係合部７５と第４枢軸４４の係合の際に、主部７１がソケット部３１から突出しており、この主部７１または主部７１の端部の架橋部７２を押し込むことにより係合できること、および第４枢軸４４がソケット部３１において開口３１ａ寄りに配置されていることにより、作業性良く規制部材６０の装着を行うことができる。 In the mounting process of the regulating member 70, the main portion 71 is pinched with a finger, the second engaging portion 78 is engaged with the second pivot 42 located outside the socket portion 31, and the regulating member 70 is turned. 1 When the engaging portion 75 is engaged with the fourth pivot 44, and when the first engaging portion 75 and the fourth pivot 44 are engaged, the main portion 71 protrudes from the socket portion 31, and this main portion The restricting member 60 can be mounted with good workability because it can be engaged by pushing the bridge portion 72 at the end of the 71 or the main portion 71, and the fourth pivot 44 is arranged closer to the opening 31a in the socket portion 31. It can be carried out.

本実施形態の規制部材７０は、第３実施形態と同様に第４枢軸４４のみならず第２枢軸４２にも係合されているので、扉３および取付部材３０の開閉に伴い、第２リンク４６と一緒に回動する。
図１７（Ａ），（Ｂ）に示すように、扉３および取付部材３０が閉位置にある時、規制部材７０の架橋部７２と一対の荷重受部７３はソケット部３１内に収容されている。規制部材７０の主部７１は湾曲しているので、主部７１において筺体２の側壁２ｂに対向する部位は、ソケット部３１内に収容されており側壁２ｂと干渉しない。 Since the regulation member 70 of the present embodiment is engaged not only with the fourth pivot 44 but also with the second pivot 42 as in the third embodiment, the second link is linked with the opening and closing of the door 3 and the mounting member 30. Rotate with 46.
As shown in FIGS. 17A and 17B, when the door 3 and the mounting member 30 are in the closed position, the bridging portion 72 of the regulating member 70 and the pair of load receiving portions 73 are housed in the socket portion 31. There is. Since the main portion 71 of the regulating member 70 is curved, the portion of the main portion 71 facing the side wall 2b of the housing 2 is housed in the socket portion 31 and does not interfere with the side wall 2b.

図１８（Ａ），（Ｂ）に示すように、扉３および取付部材３０が開位置にある時、第１リンク４５の一対の側板部４５ｂが規制部材７０の一対の荷重受部７３に当たり、一対の側板部４５ｂとソケット部３１の開口３１ａの縁部との間で一対の荷重受部７３が挟まれる。この状態で、ソケット部３１の開口３１ａの縁部が規制部材７０の架橋部７２に形成された溝７９に入り込み、その当接面７９ａに当っている。 As shown in FIGS. 18A and 18B, when the door 3 and the mounting member 30 are in the open position, the pair of side plate portions 45b of the first link 45 hit the pair of load receiving portions 73 of the regulating member 70. A pair of load receiving portions 73 are sandwiched between the pair of side plate portions 45b and the edge portion of the opening 31a of the socket portion 31. In this state, the edge portion of the opening 31a of the socket portion 31 enters the groove 79 formed in the crosslinked portion 72 of the regulating member 70 and hits the contact surface 79a thereof.

容易に理解できるので図示しないが、第４実施形態の規制部材７０は、第１リンク４５と第４枢軸４４との間で挟まれることにより、又は第２リンク４６とソケット部３１の開口３１ａの縁部とで挟まれることにより、扉３および取付部材３０の開位置を定めるようにしてもよい。 Although not shown because it is easily understood, the regulating member 70 of the fourth embodiment is sandwiched between the first link 45 and the fourth pivot 44, or the opening 31a of the second link 46 and the socket portion 31. The open position of the door 3 and the mounting member 30 may be determined by being sandwiched between the edges.

本発明は、上記実施に制約されず、その要旨を逸脱しない範囲において各種の変形例を採用することができる。
例えば、第３実施形態において、第１係合部６５の収容空間６５ａの内周の角度範囲は１８０°以下であってもよい。
規制部材の第１係合部と第２係合部の両方を、内周の角度範囲が１８０°を越える収容空間と、第２枢軸または第４枢軸の径より狭い幅の開放部とを有するように構成してもよい。 The present invention is not restricted to the above implementation, and various modifications can be adopted without departing from the gist thereof.
For example, in the third embodiment, the angle range of the inner circumference of the accommodation space 65a of the first engaging portion 65 may be 180 ° or less.
Both the first engaging portion and the second engaging portion of the regulating member have an accommodating space having an inner peripheral angle range of more than 180 ° and an open portion having a width narrower than the diameter of the second or fourth pivot. It may be configured as follows.
