Description

本発明は、例えば、ハンドル等を起伏可能に支持するためのヒンジ装置に関するものである。   The present invention relates to a hinge device for supporting, for example, a handle or the like so as to be raised and lowered.

この種のヒンジ装置は、特許文献1等に開示されるように、例えば折り畳み式携帯電話の分野において周知である。それ以外にも、図13に示すようなヒンジ装置が周知である。   This type of hinge device is well known in the field of a foldable mobile phone, for example, as disclosed in Patent Document 1 and the like. In addition, a hinge device as shown in FIG. 13 is well known.

この図13のヒンジ装置の例は、ヒンジベース101にヒンジ軸102よってハンドル103が起伏可能に支持されている。ハンドル103は、ヒンジ軸102に連結されたヒンジピン104と、そのヒンジピン104上にスプリング105を介在させてヒンジピン104の長さ方向に移動可能に設けられた内筒106と、その内筒106の外側に設けられたグリップ108とが備えられている。そして、グリップ108を内筒106とともにスプリング105のバネ力に抗して図12の矢印方向に移動させることにより、内筒106とヒンジベース101との圧接状態が解除されて、ハンドル103を実線で示す起立位置と2点鎖線で示す倒伏位置との配置させることができる。   In the example of the hinge device of FIG. 13, a handle 103 is supported by a hinge base 101 by a hinge shaft 102 so as to be raised and lowered. The handle 103 includes a hinge pin 104 connected to the hinge shaft 102, an inner cylinder 106 provided on the hinge pin 104 so as to be movable in the length direction of the hinge pin 104, and an outer side of the inner cylinder 106. And a grip 108 provided on the head. Then, by moving the grip 108 together with the inner cylinder 106 in the direction of the arrow in FIG. 12 against the spring force of the spring 105, the pressure contact state between the inner cylinder 106 and the hinge base 101 is released, and the handle 103 is indicated by a solid line. The standing position shown and the lying position shown by a two-dot chain line can be arranged.

特開2006−161971号公報JP 2006-161971 A

図13に示す従来構成においては、グリップ108内にそのグリップ108をヒンジピン104にに対してスライドさせる機能を設けるため、スプリング105や内筒106等を組み込む必要があるため、グリップ108は専用の形状となり、図13に示すグリップ108以外の汎用のグリップを使用することは困難である。加えて、ハンドル103がヒンジ軸102によって支持されているため、ハンドル103の起伏方向がヒンジ軸102と直交する一つの平面内に制限される。   In the conventional configuration shown in FIG. 13, since the grip 108 is provided with a function of sliding the grip 108 relative to the hinge pin 104, it is necessary to incorporate the spring 105, the inner cylinder 106, and the like. Therefore, it is difficult to use a general-purpose grip other than the grip 108 shown in FIG. In addition, since the handle 103 is supported by the hinge shaft 102, the undulation direction of the handle 103 is limited to one plane orthogonal to the hinge shaft 102.

この発明の目的は、構成が簡単で、汎用性を有し、しかもハンドルの起伏方向を自在に設定できるヒンジ装置を提供することにある。   An object of the present invention is to provide a hinge device that has a simple configuration, is versatile, and can freely set the direction of undulation of a handle.

上記の目的を達成するために、本発明においては、ヒンジ本体と、そのヒンジ本体に対して起伏可能に支持されたヒンジピンとを備えたヒンジ装置において、前記ヒンジ本体の内部に空間を形成するとともに、その空間とヒンジ本体の外側面との間には前記ヒンジピンの起伏を案内するガイド溝を形成し、前記ヒンジピンの先端には前記ガイド溝より幅広の当接部を形成し、ヒンジピンを前記空間内に向かって付勢する付勢部材を設けたことを特徴とする。   In order to achieve the above object, according to the present invention, in a hinge device including a hinge body and a hinge pin supported so as to be raised and lowered with respect to the hinge body, a space is formed inside the hinge body. A guide groove for guiding the undulation of the hinge pin is formed between the space and the outer surface of the hinge body, and a contact portion wider than the guide groove is formed at the tip of the hinge pin. An urging member for urging inward is provided.

従って、本発明においては、ヒンジピンの先端部にガイド溝より幅広の当接部が形成されているため、ヒンジピンが収容空間から外部に抜け出ることはない。従って、ヒンジベースとヒンジピンとを連結するための軸ピンが不要となり、部品点数が少なくなるとともに、軸ピンを組み付ける手間が不要になる。また、付勢手段がヒンジピンと球面との間に設けられているため、ヒンジピンにハンドルを設けた場合は、ハンドルとの間にスプリングやヒンジピンをスライドさせるための内筒を設ける必要はない。ハンドルに専用構成を備える必要はなく、そのハンドルとして汎用品を使用することができる。   Therefore, in the present invention, since the contact portion wider than the guide groove is formed at the tip portion of the hinge pin, the hinge pin does not come out of the housing space. Therefore, the shaft pin for connecting the hinge base and the hinge pin is not required, the number of parts is reduced, and the trouble of assembling the shaft pin is not required. Further, since the urging means is provided between the hinge pin and the spherical surface, when a handle is provided on the hinge pin, it is not necessary to provide an inner cylinder for sliding the spring or the hinge pin between the handle. The handle need not have a dedicated configuration, and a general-purpose product can be used as the handle.

本発明によれば、構成を簡単にすることができるとともに、ヒンジピンに汎用のハンドルを設けて用いることができる。   According to the present invention, the configuration can be simplified, and the hinge pin can be provided with a general-purpose handle.

図1〜図3に示すように、ヒンジ装置20のヒンジ本体としてのヒンジベース21にはヒンジピン22が支持されている。このヒンジピン22にはハンドル23が取付けられている。そして、ハンドル23の操作により、ハンドル23及びヒンジピン22がほぼ90度の範囲内において起伏可能に、かつ自身の軸方向に移動可能に支持されている。ここでは、図1,図5の状態をハンドル23の倒伏状態、図2,図7,図8の状態をハンドル23の起立状態とする。
Hereinafter, embodiments embodying the present invention will be described. The hinge device 20 of this embodiment is used for the handle device shown in FIG.
As shown in FIGS. 1 to 3, a hinge pin 22 is supported on a hinge base 21 as a hinge body of the hinge device 20. A handle 23 is attached to the hinge pin 22. By the operation of the handle 23, the handle 23 and the hinge pin 22 are supported so as to be able to rise and fall within a range of approximately 90 degrees and to be movable in the axial direction of the handle 23. Here, the state shown in FIGS. 1 and 5 is the lying state of the handle 23, and the states shown in FIGS. 2, 7 and 8 are the standing state of the handle 23.

図3及び図4に示すように、前記ヒンジベース21の内部には収容空間31が形成されている。この収容空間31の内部には円筒面311が形成されるとともに、内端部には球面312が形成されている。収容空間31の球面312と反対側の端部は外部に向かって開放されている。図1及び図2に示すように、ヒンジベース21にはその頂部から側部にかけてほぼ90度の範囲にわたって収容空間31とヒンジベース21の外側とを連通させるガイド溝32が形成されている。図9〜図11に示すように、このガイド溝32の幅αは、収容空間31の内径βより狭く形成されている。ガイド溝32の両端321は半円状に形成されている。   As shown in FIGS. 3 and 4, an accommodation space 31 is formed inside the hinge base 21. A cylindrical surface 311 is formed inside the accommodation space 31, and a spherical surface 312 is formed at the inner end. The end of the accommodation space 31 opposite to the spherical surface 312 is open to the outside. As shown in FIGS. 1 and 2, the hinge base 21 is formed with a guide groove 32 that allows the accommodation space 31 to communicate with the outside of the hinge base 21 over a range of approximately 90 degrees from the top to the side. As shown in FIGS. 9 to 11, the width α of the guide groove 32 is narrower than the inner diameter β of the accommodation space 31. Both ends 321 of the guide groove 32 are formed in a semicircular shape.

図3に示すように、収容空間31の開放部には蓋部材33が嵌合状態で固定されている。従って、蓋部材33によって収容空間31の開放部が閉鎖されている。蓋部材33の収容空間31側の中心部には突起34が形成されるとともに、その突起34の中心位置にはネジ孔35が貫設されている。そして、ヒンジベース21が図示しない所要の部材上に設置された状態で、このネジ孔35に螺合される図示しないネジによってヒンジベース21が図示しない所要の部材に固定される。   As shown in FIG. 3, a lid member 33 is fixed to the open portion of the accommodation space 31 in a fitted state. Accordingly, the open portion of the accommodation space 31 is closed by the lid member 33. A projection 34 is formed at the center of the lid member 33 on the housing space 31 side, and a screw hole 35 is provided at the center of the projection 34. Then, with the hinge base 21 installed on a required member (not shown), the hinge base 21 is fixed to a required member (not shown) by a screw (not shown) screwed into the screw hole 35.

図1〜図3に示すように、前記ヒンジピン22は前記ガイド溝32内において移動可能に設けられており、ヒンジピン22の一端が収容空間31内に位置するとともに、他端がヒンジベース21の外側に位置している。ヒンジピン22の両側面には平面40が形成されており、この平面40とガイド溝32の内面との当接によってヒンジピン22の自身の軸線を中心とした回転が阻止される。   As shown in FIGS. 1 to 3, the hinge pin 22 is movably provided in the guide groove 32, and one end of the hinge pin 22 is located in the accommodation space 31 and the other end is outside the hinge base 21. Is located. Flat surfaces 40 are formed on both side surfaces of the hinge pin 22, and the rotation of the hinge pin 22 around its own axis is prevented by contact between the flat surface 40 and the inner surface of the guide groove 32.

図3及び図4に示すように、ヒンジピン22の先端にはフランジ41が形成され、その前面には前記球面312と同様な曲率の球面411が形成されている。ヒンジピン22の外周には受けリング42が摺動可能に外嵌され、その後面には球面312と同様な曲率の球面421が形成されている。フランジ41と受けリング42との間には圧縮スプリング43が介在され、このスプリング43によってヒンジピン22が収容空間31内に向かう前方へ、受けリング42が後方へ付勢されている。このため、フランジ41の球面411及び受けリング42の球面421が収容空間31の球面312にバネ力の作用下において当接される。   As shown in FIGS. 3 and 4, a flange 41 is formed at the tip of the hinge pin 22, and a spherical surface 411 having the same curvature as the spherical surface 312 is formed on the front surface thereof. A receiving ring 42 is slidably fitted on the outer periphery of the hinge pin 22, and a spherical surface 421 having the same curvature as the spherical surface 312 is formed on the rear surface. A compression spring 43 is interposed between the flange 41 and the receiving ring 42, and the spring pin urges the hinge pin 22 forward toward the inside of the accommodation space 31 and the receiving ring 42 backward. Therefore, the spherical surface 411 of the flange 41 and the spherical surface 421 of the receiving ring 42 are brought into contact with the spherical surface 312 of the receiving space 31 under the action of a spring force.

なお、ここで球面312,411,421の形状は、真(円)球の面だけではなく、真球面に近似した楕円球面等の曲面を含むものとする。
ヒンジピン22の前端部には前記蓋部材33の突起34の外径より大きな内径の嵌合孔44が形成されている。ヒンジピン22の後端部にはネジ孔45が形成されている。このネジ孔45には、前記ハンドル23の取付ネジ46が螺着されている。なお、この取付ネジ46は、ハンドル23に取り付けられた連結ロッド47の先端部に形成されている。ハンドル23の外側のグリップ48は連結ロッド47に対して所定範囲内において軸方向に移動可能に、かつ軸を中心に回転可能に外嵌されている。
Here, the shapes of the spherical surfaces 312, 411, and 421 include not only a true (circular) spherical surface but also a curved surface such as an elliptical spherical surface approximated to a true spherical surface.
A fitting hole 44 having an inner diameter larger than the outer diameter of the protrusion 34 of the lid member 33 is formed at the front end of the hinge pin 22. A screw hole 45 is formed in the rear end portion of the hinge pin 22. An attachment screw 46 of the handle 23 is screwed into the screw hole 45. The attachment screw 46 is formed at the tip of a connecting rod 47 attached to the handle 23. The grip 48 outside the handle 23 is externally fitted to the connecting rod 47 so as to be movable in the axial direction within a predetermined range and to be rotatable about the shaft.

図7に示すように、連結ロッド47の先端には六角孔472が形成されている。そして、図示しない六角レンチが前記蓋部材33のネジ孔35を通して六角孔472内に挿入されることにより、連結ロッド47をヒンジピン22に対して回転させて、その取付ネジ46がヒンジピン22のネジ孔45に対して螺合または螺退される。   As shown in FIG. 7, a hexagon hole 472 is formed at the tip of the connecting rod 47. Then, a hexagon wrench (not shown) is inserted into the hexagon hole 472 through the screw hole 35 of the lid member 33, whereby the connecting rod 47 is rotated with respect to the hinge pin 22, and the mounting screw 46 is screw hole of the hinge pin 22. 45 is screwed or screwed.

次に、以上のように構成された実施形態の作用を説明する。
図1及び図5は、ハンドル23が倒伏された状態を示している。この状態においては、図9に示すように、ヒンジピン22の両側の平面40の下縁がガイド溝32の半円形をなす両端321の上縁に受けられている。また、スプリング43の付勢力により、ヒンジピン22のフランジ41がガイド溝32の内縁に当接されている。そして、同じくスプリング43の付勢力により、フランジ41の球面411及び受けリング42の球面421がヒンジベース21の収容空間31の球面312に当接している。
Next, the operation of the embodiment configured as described above will be described.
1 and 5 show a state in which the handle 23 is laid down. In this state, as shown in FIG. 9, the lower edge of the plane 40 on both sides of the hinge pin 22 is received by the upper edge of both ends 321 forming the semicircular shape of the guide groove 32. Further, the flange 41 of the hinge pin 22 is in contact with the inner edge of the guide groove 32 by the biasing force of the spring 43. Similarly, due to the urging force of the spring 43, the spherical surface 411 of the flange 41 and the spherical surface 421 of the receiving ring 42 are in contact with the spherical surface 312 of the accommodation space 31 of the hinge base 21.

前記の倒伏状態において、ハンドル23を図1及び図5の上方へ起立回転させれば、図6に示すように、ヒンジピン22がガイド溝32及び収容空間31の球面312に沿って同図の反時計回り方向へ移動される。このとき受けリング42は球面421と当接してヒンジピン22の後部側(ハンドル23側)への移動が拘束されている。   If the handle 23 is rotated upright in FIGS. 1 and 5 in the above-mentioned lying state, the hinge pin 22 moves along the guide groove 32 and the spherical surface 312 of the receiving space 31 as shown in FIG. Moves clockwise. At this time, the receiving ring 42 abuts on the spherical surface 421 and the movement of the hinge pin 22 toward the rear side (the handle 23 side) is restricted.

このようにして、フランジ41の球面411が収容空間31の球面312から外れて、円筒面311側に移行する。そして、図7に示すように、ヒンジピン22の先端と突起34との当接状態が外れて、突起34と嵌合孔44とが対向すると、スプリング43の付勢力によってヒンジピン22が蓋部材33側に移動され、ヒンジピン22の嵌合孔44が蓋部材33の突起34の外側に嵌る。従って、この状態で、ハンドル23が起立され、この起立状態で固定される。このため、ハンドル23を持って所要の作業を行なうことができる。   In this way, the spherical surface 411 of the flange 41 deviates from the spherical surface 312 of the accommodation space 31 and moves to the cylindrical surface 311 side. As shown in FIG. 7, when the contact state between the tip of the hinge pin 22 and the projection 34 is released and the projection 34 and the fitting hole 44 face each other, the biasing force of the spring 43 causes the hinge pin 22 to move to the lid member 33 side. The fitting hole 44 of the hinge pin 22 is fitted to the outside of the protrusion 34 of the lid member 33. Therefore, in this state, the handle 23 is erected and fixed in this erected state. For this reason, it is possible to carry out the required work with the handle 23.

ハンドル23を倒伏位置に戻す場合には、図8に示すように、ヒンジピン22をスプリング43の付勢力に抗して引き上げ、嵌合孔44を突起34から離脱させる。そして、前記とは逆の順にヒンジピン22を倒伏側に回転させれば、図1に示す倒伏状態になる。   When returning the handle 23 to the lying down position, as shown in FIG. 8, the hinge pin 22 is pulled up against the urging force of the spring 43, and the fitting hole 44 is detached from the protrusion 34. And if the hinge pin 22 is rotated to the lying side in the reverse order, the lying state shown in FIG.

前記のハンドル23の起立及び倒伏動作の場合、スプリング43の付勢力によって受けリング42の球面421が収容空間31の球面312に押し付けられるが、球面どうしの当接であるため、ヒンジピン22の移動がスムーズになり、ハンドル23を無理なく起伏動作させることができる。   In the case where the handle 23 is raised and laid down, the spherical surface 421 of the receiving ring 42 is pressed against the spherical surface 312 of the receiving space 31 by the urging force of the spring 43, but since the spherical surfaces are in contact with each other, the movement of the hinge pin 22 is performed. It becomes smooth and the handle 23 can be raised and lowered without difficulty.

なお、六角レンチをネジ孔45を通して、その先端をヒンジピン22の先端の六角孔472に挿入して回せば、ヒンジピン22は両側の平面とガイド溝32の当接により回転し得ないため、ロッド47が回る。従って、ロッド47とヒンジピン22との連結を解除して、ハンドル23をヒンジピン22から外すことができる。   If the hex wrench is inserted through the screw hole 45 and the tip of the hex wrench is inserted into the hex hole 472 at the tip of the hinge pin 22 and rotated, the hinge pin 22 cannot rotate due to the contact between the flat surfaces on both sides and the guide groove 32. Turns around. Accordingly, the connection between the rod 47 and the hinge pin 22 can be released, and the handle 23 can be detached from the hinge pin 22.

この実施形態においては、以下の効果がある。
・ガイド溝32の幅αが収容空間31の内径βより狭く、かつヒンジピン22の収容空間31側の端部にフランジ41が形成されているため、ヒンジピン22が収容空間31から外部に抜け出ることはない。従って、ヒンジベース21とヒンジピン22とを連結するための軸ピンが不要である。このため、部品点数が少なくなるとともに、軸ピンを組み付ける手間が不要になる。
This embodiment has the following effects.
-Since the width α of the guide groove 32 is narrower than the inner diameter β of the receiving space 31 and the flange 41 is formed at the end of the hinge pin 22 on the receiving space 31 side, the hinge pin 22 is not pulled out of the receiving space 31 to the outside. Absent. Therefore, a shaft pin for connecting the hinge base 21 and the hinge pin 22 is not necessary. For this reason, the number of parts is reduced, and the trouble of assembling the shaft pin is not required.

・スプリング43が収容空間31内においてフランジ41と受けリング42との間に設けられているため、ヒンジピン22とハンドル23との間にスプリングやヒンジピンをスライドさせるための内筒を設ける必要はない。このため、図13に示す従来構成とは異なり、ハンドル23に専用構成を備える必要はなく、そのハンドル23として汎用品を使用することができる。   Since the spring 43 is provided between the flange 41 and the receiving ring 42 in the accommodation space 31, it is not necessary to provide an inner cylinder for sliding the spring or the hinge pin between the hinge pin 22 and the handle 23. Therefore, unlike the conventional configuration shown in FIG. 13, it is not necessary to provide the handle 23 with a dedicated configuration, and a general-purpose product can be used as the handle 23.

・フランジ41の球面411が収容空間31の球面312に沿う曲率半径の球面によって構成されているため、球面411が球面312に沿ってスムーズに移動される。従って、ハンドル23を拗れ等がほとんど生じることなく円滑に起伏させることができる。   Since the spherical surface 411 of the flange 41 is constituted by a spherical surface having a radius of curvature along the spherical surface 312 of the accommodating space 31, the spherical surface 411 is smoothly moved along the spherical surface 312. Therefore, the handle 23 can be smoothly raised and lowered with little twisting or the like.

・ヒンジピン22の先端のフランジ41に球面411を形成するとともに、受けリング42にも球面421を形成したため、ヒンジピン22及び受けリング42の球面411,421と収容空間31の球面312との接触が球面どうしの接触となる。このため、ヒンジピン22の倒伏動作がスムーズになるばかりでなく、ヒンジピン22や受けリング42の早期摩耗を防止できて、耐久性を向上できる。特に、常に収容空間31の球面312に当接する受けリング42の当接面を球面421にしたことにより、前記のスムーズな動作や耐久性の向上に好適である。   Since the spherical surface 411 is formed on the flange 41 at the tip of the hinge pin 22 and the spherical surface 421 is also formed on the receiving ring 42, contact between the spherical surfaces 411 and 421 of the hinge pin 22 and the receiving ring 42 and the spherical surface 312 of the receiving space 31 is spherical. It will be a contact between them. For this reason, not only does the overturning operation of the hinge pin 22 become smooth, but early wear of the hinge pin 22 and the receiving ring 42 can be prevented, and durability can be improved. In particular, the contact surface of the receiving ring 42 that always contacts the spherical surface 312 of the accommodating space 31 is a spherical surface 421, which is suitable for the smooth operation and the improvement of the durability.

・ヒンジピン22の外周にヒンジベース21の球面312に当接可能な受けリング42をヒンジピン22の軸方向に移動可能に設け、その受けリング42とヒンジピン22のフランジ41との間にスプリング43を設けため、スプリング43が球面に直接接触することはなく、円滑な動作を得ることができる。   A receiving ring 42 that can contact the spherical surface 312 of the hinge base 21 is provided on the outer periphery of the hinge pin 22 so as to be movable in the axial direction of the hinge pin 22, and a spring 43 is provided between the receiving ring 42 and the flange 41 of the hinge pin 22. Therefore, the spring 43 does not directly contact the spherical surface, and a smooth operation can be obtained.

For this reason, the work performed with the handle 23 can be stably performed.

本発明は前記実施形態に限定されるものではなく、例えば以下のように具体化してもよい。
・本発明のヒンジ装置20をハンドル装置以外の装置において用いること。例えば、図12に示すように、ヒンジ装置20を箱61とその蓋62との間に設けたり、ヒンジ装置20を建物においてドアフレームとドアとの間に設けたりすること。図12に示すように、ヒンジ装置20を箱61と蓋62との間に設けた場合には、蓋62を閉鎖する直前及び開放開始時に蓋62を箱61の開口面と直角をなす方向に移動させることができる。従って、箱61の開口に設けられたシール63に対して蓋62による捩れ力や擦過がほとんど作用しないため、シール63の損傷防止に有効である。
The present invention is not limited to the above embodiment, and may be embodied as follows, for example.
-The hinge device 20 of the present invention is used in devices other than the handle device. For example, as shown in FIG. 12, the hinge device 20 is provided between the box 61 and its lid 62, or the hinge device 20 is provided between a door frame and a door in a building. As shown in FIG. 12, when the hinge device 20 is provided between the box 61 and the lid 62, the lid 62 is set in a direction perpendicular to the opening surface of the box 61 immediately before the lid 62 is closed and at the start of opening. Can be moved. Therefore, since the twisting force and rubbing by the lid 62 hardly act on the seal 63 provided in the opening of the box 61, it is effective in preventing damage to the seal 63.

・図1に2点鎖線で示すように、ガイド溝32を複数設けること。あるいは、ガイド溝32を90度の範囲を超えるように延長したり、90度の範囲より狭くなるように短くしたりすること。図1のようにガイド溝32を複数設ければ、ハンドル23を複数の異なる方向において起伏させることができる。また、ハンドル23の起伏範囲を例えば180度のように広い範囲に設定できる。このように、ハンドル23を任意の方向に起伏させたり、ハンドル23の起伏範囲を拡げたりすることができる。   -Provide a plurality of guide grooves 32 as shown by a two-dot chain line in FIG. Alternatively, the guide groove 32 is extended so as to exceed the range of 90 degrees, or shortened so as to be narrower than the range of 90 degrees. If a plurality of guide grooves 32 are provided as shown in FIG. 1, the handle 23 can be raised and lowered in a plurality of different directions. Further, the undulation range of the handle 23 can be set to a wide range, for example, 180 degrees. As described above, the handle 23 can be raised and lowered in an arbitrary direction, and the range of the handle 23 can be expanded.

・蓋部材33及びヒンジピン22の凹凸を逆にすること。ただし、この場合は、ヒンジピン22側の突部を低くする必要がある。
・ヒンジピン22のフランジ41の球面411を円錐面等の他の形状の面にすること。
-Reverse the unevenness of the lid member 33 and the hinge pin 22. However, in this case, the protrusion on the hinge pin 22 side needs to be lowered.
-Make the spherical surface 411 of the flange 41 of the hinge pin 22 into a surface of another shape such as a conical surface.

・前記収容空間31内の球面312を平坦面等の球面以外の形状の面に変更すること。このように構成しても、スプリング43の付勢力が弱ければ、あるいは図7の状態において付勢力が無くなればヒンジピン22の起伏動作は可能である。   The spherical surface 312 in the accommodation space 31 is changed to a surface having a shape other than a spherical surface such as a flat surface. Even with this configuration, if the urging force of the spring 43 is weak, or if the urging force disappears in the state of FIG. 7, the raising and lowering operation of the hinge pin 22 is possible.
