Description

本発明は、携帯電話，モバイル等の電子機器の枢着部に設けるヒンジ装置並びにこのヒンジ装置を用いた電子機器に関するものである。   The present invention relates to a hinge device provided at a pivotally mounted portion of an electronic device such as a mobile phone and a mobile, and an electronic device using the hinge device.

例えば従来の折り畳み式の携帯電話は、数字キーやファンクションキーを配列した操作部を下側となる本体部の上面側に設け、この操作部のキー操作等により所定の表示がなされる液晶パネルなどのディスプレイ部を上側となる重合部（蓋部）の伏面側（重合側）に設け、この本体部と重合部とをヒンジ装置を介して連結して、本体部と重合部とを二つ折り重合して操作部を重合部により隠蔽した折り畳み閉塞状態から、ヒンジ装置により重合部を起伏回動して略反転し、操作部とディスプレイ部とが露出した開放状態に切り替えできるように構成している。   For example, a conventional foldable mobile phone is provided with an operation unit on which the numeric keys and function keys are arranged on the upper surface side of the lower main unit, and a liquid crystal panel on which a predetermined display is made by the key operation of the operation unit. The display part is provided on the lower surface side (polymerization side) of the upper overlapping part (lid part), the main body part and the overlapping part are connected via a hinge device, and the main body part and the overlapping part are folded in half. From the folded closed state where the operation part is concealed by the superposition part, the overlapping part is swung up and down by the hinge device and reversed approximately, so that the operation part and the display part can be switched to the open state. Yes.

また、従来のこのような単に起伏回動する重合部で本体部の操作部を覆う電子機器においては、折り畳み重合してコンパクト化できるものの操作部を隠蔽した重合状態ではディスプレイ部も隠蔽してしまう構造となり、コンパクト化した状態での使用が制限されざるを得なく不便である場合も多い。   In addition, in the conventional electronic device that covers the operation part of the main body part with a superposition part that simply turns up and down, the display part is also concealed in a superposition state where the operation part is concealed although it can be folded and compactized. In many cases, the structure is inconvenient and the use in a compact state must be restricted.

また、コンパクト化のため重合した閉塞状態ではディスプレイ部は隠蔽され、使用時に重合部を開放回動して立ち起こした際にはその正面側にディスプレイ部が配置されるためディスプレイ部を見やすいが、人にディスプレイ部を見せづらいし、またカメラ部をディスプレイ部とは反対面に設けている場合、自身の顔を写してディスプレイ部に表示させる場合などは本体毎操作部も裏返し反転させなければならないため、写しづらいし、シャッター操作もしにくい。   In addition, the display part is concealed in the closed state that is overlapped for compactness, and the display part is placed on the front side when it is erected by opening and turning the overlapping part during use, so it is easy to see the display part, When it is difficult to show the display part to a person, and the camera part is provided on the opposite side of the display part, if you want to display your face on the display part, etc. Therefore, it is difficult to shoot and the shutter operation is difficult.

そこで出願人は、開放した重合部や開放途中の所定角度で更に自転回動により表裏反転回動できるように構成し、不使用時あるいはキー操作を不要にして折り畳んだ際においても、言い換えるとたとえディスプレイ部を設けた重合部を本体部に重合して操作部を隠蔽したコンパクト化状態においても、従来通りディスプレイ部を伏面側にして操作部と共に隠蔽することも、逆に自転回動反転させてディスプレイ部が上側に配設され、コンパクト化した閉塞状態でもディスプレイ部を視認したり、機能させたりすることが可能となるようにし、またカメラ使用に際しては重合部を起こした所定角度で反転可能にしたものなどを提案した。   Therefore, the applicant is configured to be able to turn the front and back by rotating further at a predetermined angle in the middle of opening or at a predetermined angle in the middle of opening, and in other words, even when folded without using a key operation, for example, Even in a compact state where the operation unit is concealed by superimposing the overlapped part with the display unit on the main unit, the display unit can be concealed with the operation unit with the display unit facing down as before. The display unit is arranged on the upper side so that the display unit can be seen and functioned even in a compact closed state, and can be reversed at a predetermined angle when the overlapping unit is raised when using the camera. I proposed something that I made.

特にこのように起伏回動によって開閉するディスプレイ部（重合部）を反転自在に設けて、ディスプレイ部を上面にして重合コンパクト化できるため、本体部の重合側と反対側の外面（底面）にカメラ部を設けることで、コンパクト化状態でディスプレイ部を見ながらカメラ撮りでき、携帯電話でありながら、反転して折り畳むことでデジタルカメラと全く同様な使用が行なえるように設計することが可能となる。   In particular, the display part (overlapping part) that opens and closes by undulating rotation can be provided in a reversible manner, and the display part can be made compact with the display part on the top surface. By providing the unit, it is possible to take a camera while looking at the display unit in a compact state, and it can be designed to be used exactly the same as a digital camera by flipping and folding while it is a mobile phone. .

即ち、起伏回動のみにより開閉動作する従来の固定観念を打破し、開放した重合部を更に自転回動により表裏反転回動できるように構成し、不使用時あるいはキー操作を不要にして折り畳んだ際においても、従来通りディスプレイ部を伏面側にして操作部と共に隠蔽することも、逆に自転回動反転させてディスプレイ部が上側に配設され、コンパクト化した閉塞状態でもディスプレイ部を視認したり、機能させたり、前述のようにカメラ部から映像を映し出すディスプレイ部として機能させてデジタルカメラのように使用することが可能となるようにしたり、また更に改良して例えば自転回動させた反転途中では起伏回動が規制され、例えば所定の開放位置では反転できるが、その他の開放途中では自転回動できず、また開放状態での反転途中のままでは閉塞回動できず、重合部が捩れた位置のまま閉塞することで誤って操作部を押し操作したり、本体部を傷めないようにすることもでき、機器装置として使用用途が広がり、しかも前記開閉動作も容易となり、極めて扱い易く、また誤動作を防止でき、耐久性にも秀れるなど極めて実用性に秀れた画期的な携帯電話，モバイル等の電子機器を実現可能なヒンジ装置並びにこのヒンジ装置を用いた電子機器を提案した（特願２０００−４０６６６号等）。   In other words, it breaks the conventional fixed concept that opens and closes only by undulating rotation, and it is configured so that the opened overlapped part can be turned upside down by further rotation and folded when not in use or requiring no key operation. At the same time, the display part can be concealed with the operation part with the display part facing down as before, or the display part is arranged on the upper side by rotating and reversing, and the display part can be visually recognized even in a compact closed state. It can be used like a digital camera by functioning as a display unit that projects video from the camera unit as described above, or further improved, for example, reversal rotated by rotation. The undulation rotation is restricted in the middle, for example, it can be reversed at a predetermined opening position, but cannot be rotated in the middle of other opening, and it can be reversed in the opened state. If it is not closed, it cannot be rotated, and the overlapped portion is closed in a twisted position, so that the operation unit can be pushed by mistake or the main body can be prevented from being damaged, and the usage of the device can be expanded. In addition, the hinges that can be easily opened and closed, are extremely easy to handle, can prevent malfunctions, have excellent durability, such as innovative mobile phones and mobile devices that are extremely practical. And an electronic device using the hinge device have been proposed (Japanese Patent Application No. 2000-40666, etc.).

このようなヒンジ装置は、次ぎのような構成である（後述する本発明と同一構成部材には同一符号を付して説明する。）。   Such a hinge device has the following configuration (the same components as those of the present invention to be described later are described with the same reference numerals).

第一部材２（本体部２）と第二部材４（重合部４）とを互いに重合した閉塞状態から開放回動して重合面が露出する開放状態となるように起伏回動自在にして、且つ第一部材２に対して相対的に開放回動する第二部材４を相対的に自転回動自在にして第二部材４の重合伏面と露出面とを反転切り替え自在に連結するヒンジ装置Ｈであって、起伏回動軸部９を備えた開閉回動ヒンジ部ＨＡの一方の取付部５を前記第一部材２に連結し、他方の取付部６を前記自転回動軸部16を備えた自転回動ヒンジ部ＨＢを介して前記第二部材４に連結して、前記自転回動ヒンジ部ＨＢを前記開閉回動ヒンジ部ＨＡにより起伏回動自在に設け、この開閉回動ヒンジ部ＨＡと自転回動ヒンジ部ＨＢとに、前記第一部材２に対して前記第二部材４が互いに重合した閉塞状態から所定角度開放回動した所定の回動位置若しくは所定角度以上開放回動した開放状態においては、前記第二部材４を前記第一部材２に対して少なくとも１８０度反転回動自在となり、且つ少なくとも前記所定角度以上開放回動していない回動位置では、前記第二部材４を前記第一部材２に対して、前記第二部材４と第一部材２とが重合し得る捩れのない自転回動位置から自転回動不能若しくは所定角度以上自転回動不能となる回動規制機構Ｓを設け、前記開閉回動ヒンジ部ＨＡの起伏回動軸部９に対して回動自在に設けた前記自転回動ヒンジ部ＨＢの軸取付部10に前記自転回動軸部16を自転回動自在に設け、この前記自転回動ヒンジ部ＨＡの前記軸取付部10内側へ突出する端部に、前記第二部材４の自転回動と共に自転回動し、且つ前記第二部材４の起伏回動により起伏回動する係止部７を設け、この係止部７の自転回動並びに起伏回動を規制する規制部８を前記軸取付部10の内側であってこの軸取付部10を回動自在に設けた前記開閉回動ヒンジ部ＨＡの起伏回動軸部９に設けた構成としている。前記軸取付部10はコ字状部材とし、このコ字状部材の両脚部10Ａを前記起伏回動軸部９に回動自在に設けると共に、架設部10Ｂに前記自転回動軸部16を自転回動自在に設け、このコ字状の軸取付部10の内側の脚部10Ａ間の起伏回動軸部９の外面を次のような形状に設計している。即ち、前記第一部材２と前記第二部材４とが重合し得る捩れのない自転回動位置では前記第二部材４の起伏回動を許容し、且つ互いに重合した閉塞状態から所定角度開放回動した所定の回動位置若しくは所定角度以上開放回動した開放状態においては、前記第二部材４を前記第一部材２に対して少なくとも１８０度反転回動することを許容するが、前記所定角度以上開放回動していない回動位置では、前記第二部材４を前記第一部材２に対して、前記第二部材４と第一部材２とが重合し得る捩れのない自転回動位置から自転回動不能若しくは所定角度以上自転回動不能となるように前記係止部７に対する前記規制部８の外面形状を設定して、前記回動規制機構Ｓを構成している。   The first member 2 (main body portion 2) and the second member 4 (overlapping portion 4) are pivoted up and down so as to be in an open state in which the overlapping surface is exposed by opening and rotating from the closed state where they are overlapped with each other, Further, the hinge device for connecting the overlapped surface and the exposed surface of the second member 4 so as to be able to be reversed and switched by making the second member 4 that rotates and rotates relative to the first member 2 relatively rotatable. H, one attachment portion 5 of the opening / closing rotation hinge portion HA provided with the undulating rotation shaft portion 9 is connected to the first member 2, and the other attachment portion 6 is connected to the rotation rotation shaft portion 16. The rotation rotation hinge portion HB is connected to the second member 4 via the rotation rotation hinge portion HB provided, and the rotation rotation hinge portion HB is provided so as to be freely raised and lowered by the opening / closing rotation hinge portion HA. Closed in which the second member 4 overlaps the first member 2 on the HA and the rotation pivoting hinge HB. The second member 4 is rotatable at least 180 degrees with respect to the first member 2 in a predetermined rotation position that is opened and rotated by a predetermined angle from the state or in an open state that is opened and rotated more than a predetermined angle; At least in the rotation position where the rotation is not more than the predetermined angle, the second member 4 is rotated relative to the first member 2 without twisting so that the second member 4 and the first member 2 can overlap. A rotation restricting mechanism S that cannot rotate or rotate at a predetermined angle or more from the rotation position is provided, and the rotation restricting mechanism S that is rotatable with respect to the undulating rotation shaft portion 9 of the opening / closing rotation hinge portion HA is provided. The rotation rotation shaft portion 16 is provided on the shaft mounting portion 10 of the rotation rotation hinge portion HB so as to be capable of rotation rotation, and the end portion of the rotation rotation hinge portion HA that protrudes to the inside of the shaft attachment portion 10 The second member 4 rotates and rotates together with the rotation of the second member 4, and the A locking portion 7 is provided to turn up and down by the up-and-down rotation of the second member 4, and the regulating portion 8 that restricts the rotation and up-and-down rotation of the locking portion 7 is provided inside the shaft mounting portion 10. The shaft mounting portion 10 is provided on the undulating rotation shaft portion 9 of the opening / closing rotation hinge portion HA provided rotatably. The shaft mounting portion 10 is a U-shaped member, and both leg portions 10A of the U-shaped member are rotatably provided on the undulating rotation shaft portion 9, and the rotation rotation shaft portion 16 is rotated on the erection portion 10B. The outer surface of the undulating rotation shaft portion 9 between the leg portions 10A on the inner side of the U-shaped shaft mounting portion 10 is designed in the following shape. That is, at the rotation rotation position where the first member 2 and the second member 4 can overlap, the second member 4 is allowed to rotate up and down, and the first member 2 and the second member 4 are rotated at a predetermined angle from the closed state where they overlap each other. The second member 4 is allowed to be rotated and rotated at least 180 degrees with respect to the first member 2 in the opened position in which the second member 4 is opened or rotated more than a predetermined angle. In the rotation position where the above-mentioned rotation is not performed, the second member 4 is moved from the rotation rotation position where the second member 4 and the first member 2 can overlap with each other with respect to the first member 2. The rotation restricting mechanism S is configured by setting the outer surface shape of the restricting portion 8 with respect to the locking portion 7 so that the rotation cannot be rotated or the rotation cannot be rotated more than a predetermined angle.

例えば、前記係止部７が重合部４の自転回動と共に規制部８に対して自転回動し、重合部４の起伏回動と共に規制部８に対して公転回動するが、この係止部７を太鼓状や楕円状などの短径部と長径部とを有する平板形状や凹面形状とし、規制部８をこれを受ける凹状形状としている。この係止部７と規制部８の形状はこれに限らず様々に設計可能であるが、例えば係止部７を自転回転面に対して、長辺部と短辺部とを有する平板形状とした場合には、起伏回動軸部９の太径部間を凹設状態に設けて規制部８を形成するが（太径の起伏回動軸部９の中央部を堀り込んだ状態として起伏回動軸部９の外面部に規制部８を形成するが）、自転回動自在とすべき位置に係止部７が配されるときには、これを許容するように四方に十分な径を有する凹部形状とし、且つ所定自転回動向きで起伏回動を許容するため、起伏回動軸部９の回動方向に係止部７の公転移動（起伏回動）を許容する凹部形状とし、前記凹部空間とこの凹部空間とが連設するように形成し、この起伏回動を許容する連設凹部部分は、自転回動を阻止するため、短辺部より幅広いが長辺部より幅狭い形状とする。   For example, the locking portion 7 rotates and rotates with respect to the restricting portion 8 together with the rotation of the overlapping portion 4, and revolves and rotates with respect to the restricting portion 8 together with the undulating rotation of the overlapping portion 4. The portion 7 has a flat plate shape or a concave shape having a short diameter portion and a long diameter portion such as a drum shape or an ellipse shape, and the restriction portion 8 has a concave shape for receiving it. The shape of the locking portion 7 and the regulating portion 8 is not limited to this, and can be designed in various ways. For example, the locking portion 7 has a flat plate shape having a long side portion and a short side portion with respect to the rotation surface of rotation. In this case, the restricting portion 8 is formed by providing a concave portion between the large diameter portions of the undulating rotation shaft portion 9 (the central portion of the large diameter undulating rotation shaft portion 9 is dug) Although the restricting portion 8 is formed on the outer surface portion of the undulating rotation shaft portion 9), when the locking portion 7 is disposed at a position where it should be able to rotate and rotate, a sufficient diameter in all directions is allowed to allow this. In order to allow the undulation to rotate in a predetermined rotation direction, and to allow the revolving movement (undulation rotation) of the locking portion 7 in the rotation direction of the undulation rotation shaft portion 9, The recess portion and the recess space are formed so as to be continuous with each other, and the continuous recess portion that allows the undulation rotation is prevented from rotating and rotating. Wider but a narrow shape from the long side portion.

また、別例としては、係止部７を下面が起伏回動軸部９を逃げる凹面形状として起伏回動に際して起伏回動軸部９を覆い配設しつつ起伏回動方向に公転移動できるようにし、且つこのときは自転回動が邪魔されて自転回動は阻止されるが、十分に起伏回動した位置では四方に広い凹部によって自転回動が阻止されないように構成するなど様々に設計可能である。   As another example, the engaging portion 7 has a concave surface whose bottom surface escapes the undulating rotation shaft portion 9 so that the undulation rotation shaft portion 9 can be revolved in the undulation rotation direction while covering the undulation rotation shaft portion 9 during the undulation rotation. In this case, the rotation of the rotation is obstructed and the rotation is blocked. However, it can be designed in various ways such that the rotation is not blocked by a wide recess in all directions at the fully swung position. It is.

即ち、例えば重合部４を９０度起伏回動するまでは重合部４は係止部７が規制部８に当たり干渉して自転回動できず、また、例えば本体部２と重合部４とを重合し得る捩れのない位置（０度，１８０度自動回動位置）では、規制部８内で起伏回動し、規制部８に干渉しないが、また例えば９０度重合部４を自転回動した位置では、係止部７が完全に規制部８に突き当たり略立ち起こし位置（本体部２と重合部４とが略直角となる回動位置）以上は閉塞回動できないように構成することが可能である。   That is, for example, until the overlapping portion 4 is swung up and down 90 degrees, the overlapping portion 4 cannot rotate due to the engaging portion 7 hitting the restricting portion 8 and cannot rotate, and for example, the main body portion 2 and the overlapping portion 4 are overlapped. At a position where there is no twist (0 degree, 180 degree automatic rotation position), the position is rotated up and down within the restricting portion 8 and does not interfere with the restricting portion 8, but also, for example, a position where the 90 degree overlapping portion 4 is rotated and rotated. Then, it is possible to configure so that the locking portion 7 completely contacts the restricting portion 8 and cannot be closed and rotated beyond the substantially raised position (the rotation position where the main body portion 2 and the overlapping portion 4 are substantially perpendicular). is there.

従って、前述のようにヒンジ装置を構成することで、自転回動させた反転途中では起伏回動が規制され、例えば開放位置では反転できるが、開放途中では自転回動できず、また開放状態での反転途中のままでは閉塞回動できず、重合部が捩れた位置のまま閉塞することで誤って操作部を押し操作したり、本体部を傷めないようにすることもでき、機器装置として使用用途が広がり、しかも前記開閉動作も容易となり、極めて扱い易く、また誤動作を防止でき、耐久性にも秀れるなど一層実用性に秀れた画期的な携帯電話，モバイル等の電子機器並びにこれらに用いられるヒンジ装置となる。   Therefore, by configuring the hinge device as described above, the undulation rotation is restricted during the reversal that is rotated and rotated, for example, it can be reversed at the open position, but the rotation cannot be rotated during the opening, and in the open state. It is not possible to rotate and rotate while the reversal is in progress, but it is possible to prevent the operation part from being accidentally pushed or damaged by closing the overlapped part in the twisted position. Applications are widespread, and the opening and closing operations are easy, extremely easy to handle, prevent malfunctions, have excellent durability, such as innovative mobile phones and mobile electronic devices, and these It becomes the hinge device used for.

しかしながら、ディスプレイ部が見やすいように重合部の起伏回動における最大開放角度は、１８０度でなく、１８０度よりやや小さく、例えば１６０〜１７０度位に設定している。   However, in order to make the display portion easy to see, the maximum opening angle in the undulating rotation of the overlapping portion is not 180 degrees but is slightly smaller than 180 degrees, for example, set to about 160 to 170 degrees.

この重合部の起伏回動における最大開放位置規制は、ヒンジ装置の回動部分に過回動阻止のためのストッパーを設けたり、ヒンジ装置に角度保持のため凹凸カム係合構造を設けてクリック保持するように構成することもできるが、本案では、重合部の起伏回動と自転回動を規制する係止部と規制部の形状設定により過回動を阻止してこの起伏回動における最大開放位置を規制決定するように構成している。   The maximum opening position restriction for the undulation rotation of this overlapping part is provided with a stopper to prevent over-rotation at the rotation part of the hinge device, or an uneven cam engagement structure to hold the angle in the hinge device and click hold However, in this proposal, the locking portion that restricts the undulation rotation and rotation rotation of the overlapping portion and the shape setting of the restriction portion prevent over-rotation, and the maximum opening in this undulation rotation is achieved. The position is determined so as to be regulated.

そのため、既存構造ではディスプレイ部を見やすくするために最大開放した状態では重合部は１８０度よりやや小さい角度までしか起伏回動せずディスプレイ部は手前側へやや傾いた状態となり見やすく設定している。   Therefore, in the existing structure, in order to make the display part easy to see, the overlapped part turns up and down only to a slightly smaller angle than 180 degrees in a state where it is fully opened, and the display part is slightly tilted toward the front side and is set to be easy to see.

従って、このような重合部を１８０度自転回動してディスプレイ部の向きを反転してもやはり最大開放位置は１８０度よりやや小さい角度となり、手前側へやや傾いた状態までしか開放しない。   Therefore, even if such a superposition part rotates and rotates by 180 degrees and the direction of the display part is reversed, the maximum opening position is still slightly smaller than 180 degrees, and it is opened only to a slightly inclined state.

しかし、このように反転時においても１８０度よりやや小さい角度までしか開放しないと様々な不便な点がある。   However, there are various inconveniences when opening only to an angle slightly smaller than 180 degrees even at the time of reversal.

例えば、前述のように携帯電話として構成使用する場合、重合部を折り畳み重合してコンパクト化できると共に、重合部を自転回動して反転させディスプレイ部を表面にして本体部に重合させてコンパクト化できるようにし、この本体部の底面にカメラ部を設けるように構成することでデジタルカメラとして使用できるように構成することができ非常に有用となるが、この場合、ディスプレイ部に映し出すカメラ部は、本体部の外面部（底面側）に設ける。   For example, when used as a mobile phone as described above, the overlapping part can be folded and polymerized to make it compact, and the overlapping part can be rotated and inverted to make it superimpose on the main body with the display part as the surface. It can be configured so that it can be used as a digital camera by configuring the camera unit to be provided on the bottom surface of this main body unit, but in this case, the camera unit that projects on the display unit is Provided on the outer surface (bottom side) of the main body.

このような場合、もし自分自身を撮影する場合には、折り畳まれていた重合部を開放回動し、且つ重合部を自転回動して反転させることで（ディスプレイ部３を表側にして折り畳んでいるコンパクトデジタルカメラ仕様ではすでに反転させてあるため、単にこのまま開放するだけで良いが）、ディスプレイ部を本体部外面のカメラ部と同じ側に向け、カメラ部によって映る自身の姿を同じ向きとしたディスプレイ部で視認しつつシャッター操作できる利便性を備えることとなる。   In such a case, if you want to take a picture of yourself, turn the folded overlapping part open and turn the overlapping part to rotate and reverse (fold the display part 3 upside down). Because it is already inverted in the compact digital camera specification, it is only necessary to open it as it is), but the display part is directed to the same side as the camera part on the outer surface of the main body, and the image reflected by the camera part is oriented in the same direction The convenience of being able to operate the shutter while visually recognizing on the display unit will be provided.

しかしこの場合、重合部の最大開放位置は、前述のように通常使用において開放したディスプレイ部を見やすくするための１６０〜１７０度位までしか開放できないようにしているから、１８０度まで開放回動できないため、ディスプレイ部を見づらい欠点を有する。   However, in this case, since the maximum opening position of the overlapping portion can be opened only up to about 160 to 170 degrees for easy viewing of the display portion opened in normal use as described above, the opening cannot be rotated up to 180 degrees. Therefore, it has a drawback that it is difficult to see the display unit.

本発明は、このような問題を鑑み画期的な発想の転換を図って容易な改良によって、即ち、起伏回動と自転回動を規制する係止部と規制部の形状関係の設定によって、例えばディスプレイ部を設ける重合部の起伏回動における最大開放位置を規制すると共に、反転する前と反転した後では反転後の方が起伏回動において最大開放角度が増大し、それ故利便性が向上し、これにより一層様々な使い方ができ、極めて実用性に秀れた画期的なヒンジ装置並びにヒンジ装置を用いた電子機器を提供するものである。   In view of such a problem, the present invention aims to change the groundbreaking idea and easily improve, that is, by setting the shape relationship between the locking portion and the regulating portion that regulates the undulation rotation and the rotation rotation, For example, the maximum opening position in the undulation rotation of the overlapping part where the display unit is provided is regulated, and the maximum opening angle is increased in the undulation rotation before and after inversion, thus improving convenience.

With the convenience of being able to operate the shutter while looking at the display unit with the camera unit facing the same direction as the camera unit on the outer surface of the main unit, the display unit is more open than before the reversal.

好適と考える本発明の実施形態（発明をどのように実施するか）を、図面に基づいて本発明の作用を示して簡単に説明する。   Embodiments of the present invention that are considered suitable (how to carry out the invention) will be briefly described with reference to the drawings, illustrating the operation of the present invention.

例えば閉塞状態から所定角度略以上開放回動した開放状態において、第二部材４（重合部４）を第一部材２（本体部２）に対して１８０度自転回動して再び閉塞回動し互いに重合した閉塞状態とすることで、閉塞状態における重合部４の露出面と伏面とを反転切り替えでき、前記開放状態において重合部４を自転回動して１８０度反転回動途中の捩れ位置にある場合には、少なくとも前記重合部４の端部が前記本体部２の上面に接触するに至る角度以上は閉塞回動し得ないようにも設計できる。   For example, in the open state in which the second member 4 (overlapping portion 4) is rotated by 180 degrees with respect to the first member 2 (main body portion 2) in the open state in which the open state is rotated by a predetermined angle or more from the closed state, the closed rotation is again performed. By setting the closed state overlapping each other, the exposed surface and the bottom surface of the overlapped portion 4 in the closed state can be reversed and switched, and the twisted position in the middle of the 180 ° reverse rotation by rotating the overlapped portion 4 in the open state. In this case, it can be designed so that at least the angle at which the end of the overlapping portion 4 comes into contact with the upper surface of the main body 2 cannot be closed and rotated.

また例えば重合部４の自転回動と共に自転回動し重合部４の起伏回動により自転回動ヒンジ装置ＨＢと共に起伏回動する係止部７を、自転回動ヒンジ部ＨＢの自転回動軸部16の端部にして軸取付部10内に設け、この係止部７の自転回動並びに起伏回動を規制する規制部８を前記本体部２側の開閉回動ヒンジ部ＨＡの起伏回動軸部９に設け、例えば本体部２と重合部４とが重合し得る捩れのない自転回動位置ではこの規制部８に対して係止部７が干渉することなく重合部４の起伏回動が許容され、且つ互いに重合した閉塞状態から所定角度開放回動した開放状態においても同様に重合部４を本体部２に対して１８０度反転回動することが許容されるが、所定角度以上開放回動していない回動位置では、係止部７の動きが規制部８に邪魔されて、重合部４と本体部２とが重合し得る捩れのない自転回動位置から所定角度以上の自転回動が阻止されるなど閉塞回動に際して常に捩れなく重合部４を本体部２に重合閉塞でき、捩れている場合は閉塞回動できず重合部４の端部が本体部２の上面に接触しないように、前記係止部７に対する前記規制部８の形状を設定することができる。   Further, for example, the locking portion 7 that rotates and rotates together with the rotation of the superimposing portion 4 and moves up and down together with the rotation and rotation hinge device HB by the up and down rotation of the overlapping portion 4 is connected to the rotation rotation axis of the rotation and rotation hinge portion HB. An end of the portion 16 is provided in the shaft mounting portion 10, and the restricting portion 8 for restricting the rotation and undulation rotation of the locking portion 7 is provided as the undulation of the opening / closing rotation hinge HA on the main body 2 side. For example, in the rotation rotation position where the main body portion 2 and the overlapping portion 4 can be overlapped, the locking portion 7 does not interfere with the restricting portion 8 and does not interfere with the restricting portion 8. In the open state in which the movement is allowed and the open state is rotated by a predetermined angle from the closed state where they are overlapped with each other, the overlapping portion 4 is similarly allowed to rotate 180 degrees with respect to the main body portion 2, but it is allowed to rotate more than the predetermined angle. At the rotation position where the opening is not rotated, the movement of the locking portion 7 is obstructed by the restricting portion 8 and is The overlapping portion 4 and the main body portion 2 can be overlapped and closed to the main body portion 2 without being twisted at all times during the closing rotation, for example, the rotation rotation of a predetermined angle or more is prevented from the rotation position without twisting that can be overlapped with the main body portion 2. The shape of the restricting portion 8 with respect to the locking portion 7 can be set so that the end portion of the overlapping portion 4 does not come into contact with the upper surface of the main body 2 when the twisted portion is twisted.

そして本発明は、この係止部７と規制部８との形状設定により、本体部２に対する重合部４の起伏回動における最大開放位置を規制している。   In the present invention, the maximum opening position in the undulating rotation of the overlapping portion 4 with respect to the main body portion 2 is restricted by setting the shapes of the locking portion 7 and the restricting portion 8.

即ち、係止部７の起伏回動を規制部８により阻止することで重合部４の過回動を阻止して重合部４の最大開放角度を決定している。   That is, the restricting portion 8 prevents the locking portion 7 from rotating up and down, thereby preventing the overlapping portion 4 from excessively rotating and determining the maximum opening angle of the overlapping portion 4.

この係止部７及び規制部８の形状を、前記本体部２に対する前記重合部４の起伏回動によって前記規制部８に対して前記係止部７が起伏回動する際、前記係止部７が前記規制部８に突き当たって係止部７の過回動が阻止されて前記第二部材４の最大開放位置が規制され、且つ前記第二部材４を１８０度自転回動して係止部７が１８０度自転回動した状態では最大開放位置ではまだ係止部７は規制部８に突き当たらず、前記重合部４の反転時の最大開放角度が反転前よりも増大する形状に設定した。   The shape of the locking portion 7 and the regulating portion 8 is the same as that when the locking portion 7 is swung up and down with respect to the regulating portion 8 by the up-and-down rotation of the overlapping portion 4 with respect to the main body 2. 7 abuts against the restricting portion 8 to prevent over-rotation of the locking portion 7 and the maximum opening position of the second member 4 is restricted, and the second member 4 rotates and rotates 180 degrees. In a state where the portion 7 is rotated by 180 degrees, the locking portion 7 is not yet in contact with the restricting portion 8 at the maximum opening position, and the maximum opening angle when the overlapping portion 4 is reversed is set to be larger than that before reversal. did.

例えば、後述する実施例１のように前記重合部４を起伏回動して前記係止部７を起伏回動した際、最大開放位置で前記係止部７の底面が突き当たる前記規制部８の起伏回動阻止外面若しくは係止部７の底面に凸部30を設け、この凸部30に前記係止部７の底面若しくは規制部８の起伏回動阻止外面が突き当たることで係止部７の過回動が阻止されて、この係止部７が規制部８に突き当たる回動位置が前記重合部４の最大開放位置となるように構成し、前記重合部４を１８０度自転回動して前記規制部８に対して前記係止部７が前記規制部８に対して１８０度自転回動した状態においてはこの係止部７を起伏回動した際、前記凸部30に係合する位置の前記係止部７の底面若しくは前記規制部８の起伏回動阻止外面に凹部31を設け、この凸部30に凹部31が係合することで前記最大開放位置の開放回動角度が反転前より反転後の方が増大するように構成している。   For example, as in Example 1 described later, when the overlapping portion 4 is swung up and down and the locking portion 7 is swung up and down, the bottom surface of the locking portion 7 abuts at the maximum open position. A convex portion 30 is provided on the undulating rotation preventing outer surface or the bottom surface of the engaging portion 7, and the bottom surface of the engaging portion 7 or the undulating rotation preventing outer surface of the restricting portion 8 abuts against the convex portion 30. An excessive rotation is prevented, and the rotation position where the locking portion 7 abuts against the restriction portion 8 is configured to be the maximum opening position of the overlapping portion 4, and the overlapping portion 4 is rotated 180 degrees. In a state where the locking portion 7 rotates and rotates 180 degrees relative to the restriction portion 8 with respect to the restriction portion 8, a position where the engagement portion 7 engages with the convex portion 30 when the locking portion 7 is rotated up and down. A concave portion 31 is provided on the bottom surface of the locking portion 7 or on the outer surface of the restricting portion 8 to prevent undulation rotation. Opening rotation angle of the maximum opening position by engagement is constructed as later reversed from the previous inversion is increased.

従って、例えば、前述のように携帯電話として構成使用する場合、重合部４を折り畳み重合してコンパクト化できると共に、重合部４を自転回動して反転させディスプレイ部３を表面にして本体部２に重合させてコンパクト化できるようにし、本体部２の底面にカメラ部32を設けるように構成することでコンパクトなデジタルカメラとして使用できるように構成することができ非常に有用となるが、この場合、ディスプレイ部３に映し出すカメラ部32は、本体部の外面部（底面側）に設ける。   Therefore, for example, when configured and used as a mobile phone as described above, the overlapping portion 4 can be folded and overlapped to be compact, and the overlapping portion 4 can be rotated and reversed so that the display portion 3 faces the main body portion 2. In this case, it can be used as a compact digital camera by providing a camera unit 32 on the bottom surface of the main body unit 2. The camera unit 32 projected on the display unit 3 is provided on the outer surface (bottom surface) of the main body.

このような場合でも、もし自分自身を撮影する場合には、折り畳まれていた重合部４を開放回動し、且つ重合部４を自転回動して反転させることで（ディスプレイ部３を表側にして折り畳んでいるコンパクトデジタルカメラ仕様ではすでに反転させてあるため、単にこのまま開放するだけで良いが）、ディスプレイ部３を本体部２外面のカメラ部32と同じ側に向け、カメラ部32によって映る自身の姿を同じ向きとしたディスプレイ部３で視認しつつシャッター操作できる利便性を備えることとなる。しかも、このディスプレイ部３は反転前より大きく開放回動して例えば１８０度開放回動しているためカメラ側にディスプレイ部３を向けてもこれまでと異なり反転した場合は大きく開放回動できるから見やすくなるなど、極めて実用性に秀れた画期的な携帯電話，モバイル等の電子機器並びにこれらに用いられるヒンジ装置となる。   Even in such a case, when taking a picture of himself / herself, the folded overlapping portion 4 is opened and rotated, and the overlapping portion 4 is rotated and reversed (the display portion 3 is turned to the front side). Since it has already been reversed in the compact digital camera specification that is folded, the display unit 3 faces the same side as the camera unit 32 on the outer surface of the main unit 2 and is reflected by the camera unit 32 itself. Is provided with the convenience of being able to operate the shutter while visually recognizing with the display unit 3 in the same orientation. In addition, since the display unit 3 is pivoted to open more than before reversal, for example, by 180 degrees, the display unit 3 can be largely pivoted to open if the display unit 3 is reversed unlike before. It becomes an innovative mobile phone, mobile electronic device and the like, and a hinge device used in these, which are extremely practical, such as being easy to see.

本発明の具体的な実施例１について図面に基づいて説明する。   A first embodiment of the present invention will be described with reference to the drawings.

この本体部２と重合部４との連結は、双方の端部同志の重合部分を、幅方向に配される起伏回動軸部９と、これと直交する方向に配される自転回動軸部16を有する二軸のヒンジ装置Ｈにより連結し、従来通り重合部４は起伏回動自在となり、且つ左右方向に１８０度自転回動自在（反転自在）となり、開放状態として１８０度反転回動することで、重合部４の表裏向きを切り替えでき、また互いに重合した閉塞状態における重合部４の伏面と露出面とを反転切り替えできるように構成している。   The connection between the main body portion 2 and the overlapping portion 4 is made up of the overlapping rotation portions 9 arranged in the width direction and the rotation turning shaft arranged in the direction orthogonal to the overlapping portions of both ends. Connected by a biaxial hinge device H having a portion 16, the overlapping portion 4 can rotate up and down as usual, and can rotate and rotate 180 degrees in the left and right directions (reversible), and can rotate 180 degrees as an open state. By doing so, the front and back directions of the overlapping portion 4 can be switched, and the bottom surface and the exposed surface of the overlapping portion 4 in the closed state where they are overlapped with each other can be switched in reverse.

また、本体部２の底面即ち本体部２の重合部４の重合側の外面にカメラ部32を設け、このカメラ部32の映像が重合部４のディスプレイ部３に映し出されるように構成し、反転させてディスプレイ部３を外面にして重合部４を操作部１に重合させることで折り畳んでコンパクト化した状態でデジタルカメラとして使用できるように構成している。   Further, a camera unit 32 is provided on the bottom surface of the main body 2, that is, the outer surface of the overlapping portion 4 of the main body 2, and an image of the camera portion 32 is configured to be displayed on the display unit 3 of the overlapping portion 4. Thus, the display unit 3 is arranged on the outer surface, and the superposition unit 4 is superposed on the operation unit 1 so that it can be used as a digital camera in a compact state.

次に本実施例のヒンジ装置Ｈについて説明する。   Next, the hinge apparatus H of a present Example is demonstrated.

Thus, the overlapping portion 4 and the exposed surface of the overlapping portion 4 can be rotated freely about the rotation rotation shaft portion 16 as the rotation rotation shaft portion 16. Is a hinge device H that is connected so as to be capable of being reversed and switched, wherein one attachment portion 5 of the opening / closing rotation hinge portion HA including the undulating rotation shaft portion 9 is connected to the main body portion 2 and the other attachment portion 6 is connected. Is connected to the overlapping portion 4 via a rotation rotation hinge portion HB provided with the rotation rotation shaft portion 16, and the rotation rotation hinge portion HB is undulated and rotated (revolved) by the opening / closing rotation hinge portion HA. It can be freely rotated, and the open / close rotation hinge portion HA and the rotation rotation hinge portion HB are closed. In the rotation range (open state) in which the rotation portion is opened and rotated more than a predetermined angle from the main body portion 2, the overlapping portion 4 can be rotated forward and backward by 180 degrees with respect to the main body portion 2, and the rotation that is opened and rotated to the predetermined angle. In a rotation position that does not reach the position, a rotation restriction mechanism S is provided in which rotation is prevented and rotation is impossible for a predetermined angle or more, and a state where there is no twist that overlaps with each other is held and restricted. .

即ち、本実施例では、前記閉塞状態から所定角度以上開放回動した開放状態において、重合部４を本体部２に対して１８０度自転回動して再び閉塞回動し互いに重合した閉塞状態とすることで、閉塞状態における重合部４の露出面と伏面とを反転切り替えでき、前記開放状態において重合部４を自転回動して１８０度反転回動途中の捩れ位置にある場合には、少なくとも前記重合部４の端部が前記本体部２の上面に接触するに至る角度以上は閉塞回動し得ないように前記回動規制機構Ｓを構成している。   That is, in this embodiment, in the open state in which the rotation is opened by a predetermined angle or more from the closed state, the overlapping portion 4 is rotated 180 degrees with respect to the main body portion 2 and is again closed and rotated to overlap each other. By doing so, it is possible to reversely switch the exposed surface and the bottom surface of the overlapped portion 4 in the closed state, and when the overlapped portion 4 rotates in the open state and is in a twisted position in the middle of the 180-degree reverse rotation, The rotation restricting mechanism S is configured so that at least the angle at which the end of the overlapping portion 4 comes into contact with the upper surface of the main body 2 cannot be closed and rotated.

具体的には、重合部４の自転回動と共に自転回動し重合部４の起伏回動により自転回動ヒンジ装置ＨＢと共に起伏回動する係止部７を自転回動ヒンジ部ＨＢの自転回動軸部16の端部にしてこの自転回動軸部16を自転回動自在に設けるコ字形の軸取付部10内に設け、この係止部７の自転回動並びに起伏回動を規制（許容・阻止）する規制部８を前記本体部２側の開閉回動ヒンジ部ＨＡの起伏回動軸部９に設け、本体部２と重合部４とが重合し得る捩れのない自転回動位置ではこの規制部８に対して係止部７が干渉することなく重合部４の起伏回動が許容され、且つ互いに重合した閉塞状態から所定角度以上開放回動した開放状態においても同様に重合部４を本体部２に対して１８０度反転回動することが許容されるが、所定角度以上開放回動していない回動位置では、係止部７の動きが規制部８に邪魔されて、重合部４と本体部２とが重合し得る捩れのない自転回動位置から所定角度以上の自転回動が阻止されて閉塞回動に際して重合部４の端部が本体部２の上面に接触しないように、前記係止部７に対する前記規制部８の形状が設定されている。   Specifically, the rotation portion of the rotation rotation hinge portion HB rotates the locking portion 7 that rotates and rotates together with the rotation rotation of the overlapping portion 4 and moves up and down together with the rotation rotation hinge device HB by the rotation of the overlapping portion 4. This rotation rotation shaft portion 16 is provided at the end of the moving shaft portion 16 in a U-shaped shaft mounting portion 10 provided to freely rotate, and the rotation and undulation rotation of the locking portion 7 is restricted ( A restricting portion 8 that is allowed / blocked) is provided on the undulating rotation shaft portion 9 of the opening / closing rotation hinge portion HA on the side of the main body portion 2, so that the main body portion 2 and the overlapping portion 4 can overlap with each other and rotate without rotation. Then, the overlapping portion 4 is allowed to turn up and down without the locking portion 7 interfering with the restricting portion 8, and similarly in the open state in which the overlapping portion is rotated more than a predetermined angle from the closed state where they overlap each other. 4 is allowed to rotate 180 degrees with respect to the main body 2 by rotating 180 degrees more than a predetermined angle. In the non-rotating position, the movement of the locking portion 7 is obstructed by the restricting portion 8, and the rotation rotation beyond a predetermined angle is prevented from the non-twisting rotation position where the overlapping portion 4 and the main body portion 2 can overlap. Thus, the shape of the restricting portion 8 with respect to the locking portion 7 is set so that the end portion of the overlapping portion 4 does not come into contact with the upper surface of the main body portion 2 during the closing rotation.

即ち本実施例では、本実施例の開閉回動ヒンジ部ＨＡの起伏回動軸部９に前記係止部７の起伏回動と自転回動を許容する空間（前記係止部７配設空間）としての凹所部を形成し、この凹所部を規制部８としている。   That is, in the present embodiment, the space (the space for disposing the locking portion 7) that allows the rocking and rotating shaft portion 9 of the opening and closing rotation hinge portion HA of the present embodiment to rotate and rotate the locking portion 7. ) As a restriction portion 8.

更に具体的に説明すると、自転回動ヒンジ部ＨＢの自転回動軸部16の取付座ベースとなる軸取付部10（ベース部10）をコ字形に形成し、このベース部10の対向脚部10Ａには起伏回動軸部９を挿通する軸支孔10Ｃ孔を設け、上片部（架設部10Ｂ）には自転回動軸部16を挿通する軸孔を設けている。   More specifically, a shaft mounting portion 10 (base portion 10) that serves as a mounting seat base for the rotation rotation shaft portion 16 of the rotation rotation hinge portion HB is formed in a U-shape, and the opposite leg portions of the base portion 10 are formed. 10A is provided with a shaft support hole 10C hole through which the undulating rotation shaft portion 9 is inserted, and a shaft hole through which the rotation rotation shaft portion 16 is inserted in the upper piece portion (erection portion 10B).

先ず、開閉回動ヒンジ部ＨＡについて説明すると、前記ベース部10に挿通した起伏回動軸部９を、ベース部10の側方に配した回り止め形状の筒状ケース12内に配し、この筒状ケース12内に前記起伏回動軸部９を軸として互いに凹凸係合するカム部13とカム係合部14の少なくとも一方を相対回動自在にしてスライド自在に内装し、この筒状ケース12を取付部５を介して第一部材２に係合すると共に、起伏回動軸部９の反対端も第一部材２に係合している。従って、所定起伏回動位置では、カム係合付勢とバネ11による係合付勢とで位置決め（カムロック）されるように構成し、例えば閉塞状態ではカム係合途中にあって閉塞付勢され、開放状態ではカム係合保持（カムロック）され、また起伏回動途中ではバネ付勢により回動抵抗が生じ、手を放した回動位置が保持されるフリーストップを実現できるように構成している。   First, the opening / closing rotation hinge portion HA will be described. The undulating rotation shaft portion 9 inserted through the base portion 10 is disposed in a non-rotating cylindrical case 12 disposed on the side of the base portion 10. In the cylindrical case 12, at least one of the cam portion 13 and the cam engaging portion 14 that engage with each other with the undulating rotation shaft portion 9 as an axis is slidably mounted so as to be rotatable relative to each other. 12 is engaged with the first member 2 via the attachment portion 5, and the opposite end of the undulating rotation shaft portion 9 is also engaged with the first member 2. Therefore, in the predetermined undulation rotation position, it is configured to be positioned (cam lock) by the cam engagement bias and the engagement bias by the spring 11. For example, in the closed state, the cam is biased in the middle of the cam engagement. In the open state, cam engagement is held (cam lock), and in the middle of up and down rotation, a rotation resistance is generated by spring bias, and a free stop that holds the released rotation position is realized. Yes.

本実施例では、起伏回動軸部９に挿通して共回りする前記カム部13をスライド自在に前記筒状ケース12に内装し、他方のカム係合部14は、起伏回動軸９に対して相対的に起伏回動する前記ベース部10の一方の対向脚部10Ａに凹凸を形成してこれ自体をカム係合部14としている。   In the present embodiment, the cam portion 13 that is inserted through the undulation rotation shaft portion 9 and rotates together is slidably mounted in the cylindrical case 12, and the other cam engagement portion 14 is attached to the undulation rotation shaft 9. Concavities and convexities are formed on one opposing leg portion 10A of the base portion 10 that undulates and rotates relative to the base portion 10 to form a cam engaging portion 14 itself.

また、この対向脚部10Ａ間の起伏回動軸部９に前記凹所部を形成して規制部８を設けている。   Further, the concave portion is formed in the undulating rotation shaft portion 9 between the opposing leg portions 10A, and the restricting portion 8 is provided.

そしてこの本体部２（筒状ケース12，起伏回動軸部９）に対して起伏回動するベース部10に、重合部４を自転回動ヒンジ部ＨＢを介して自転回動自在に連結している。   Then, the overlapping portion 4 is connected to the base portion 10 that rotates up and down with respect to the main body 2 (the cylindrical case 12 and the up-and-down rotation shaft portion 9) via the rotation-rotation hinge portion HB. ing.

この自転回動軸部16を備えた自転回動ヒンジ部ＨＢは、前記ベース部10（軸取付部10）の上片部（架設部10Ｂ）の軸孔に、一端（上端）に設けた取付部６を介して重合部４に連結し、他端（下端）に前記係止部７を設けた自転回動軸部16を挿通し、この自転回動軸部16（と前記取付部６）に回り止めされるカム部17を挿通すると共にこのカム部17にカム係合するカム係合部18を本実施例ではベース部10の上片部（架設部10Ｂ）に凹凸を形成して設け、前記カム部13を自転回動軸部16に沿ってスライド自在に設けると共にバネ19により係合付勢されるように構成している。   The rotation rotation hinge portion HB provided with the rotation rotation shaft portion 16 is attached to one end (upper end) of the shaft hole of the upper piece portion (erection portion 10B) of the base portion 10 (shaft attachment portion 10). It connects with the superposition | polymerization part 4 via the part 6, and the rotation rotation shaft part 16 which provided the said latching | locking part 7 in the other end (lower end) is inserted, This rotation rotation shaft part 16 (and the said attachment part 6) In this embodiment, a cam engagement portion 18 that is inserted into the cam portion 17 that is prevented from rotating and is engaged with the cam portion 17 is provided on the upper piece (the erection portion 10B) of the base portion 10 so as to be uneven. The cam portion 13 is slidably provided along the rotation rotation shaft portion 16 and is configured to be engaged and biased by a spring 19.

従って、重合部４は自転回動軸部16を軸に自転回動し、前記カム部17とカム係合部18とのカム係合により、重合閉塞状態できる捩れない回動向きではカムロックされるように構成している。   Accordingly, the overlapping portion 4 rotates and rotates about the rotation and rotation shaft portion 16 and is cam-locked in a rotation direction that cannot be twisted by the cam engagement between the cam portion 17 and the cam engagement portion 18 so that the overlapped state can be achieved. It is configured as follows.

また、捩れのない向きから１８０度自転回動する際には、バネ19に抗してカム部17がカム係合部18に対して離脱して相対回動し、０度と１８０度反転位置で開閉回動ヒンジ部ＨＡと略同様に互いに凹凸係合してカムロックされると共に、回動途中位置ではバネ付勢によりフリーストップが実現されるようにして、閉塞回動可能となる捩れのない０度，１８０度回動位置で位置決めされ、ふらつき回動しないように構成している。   In addition, when rotating 180 degrees from a direction without twisting, the cam portion 17 is separated from the cam engaging portion 18 and rotates relative to the spring 19, and is rotated at 0 ° and 180 ° inversion positions. In substantially the same manner as the opening / closing rotation hinge HA, the cams are locked by engaging the projections and depressions, and at the midway of rotation, a free stop is realized by a spring bias, so that the closing and rotation can be performed without twisting. It is positioned at the 0 degree and 180 degree rotation positions, and is configured not to wobble and rotate.

また、本実施例では配線に支障のないように略1８０度以上回動せずこの範囲において正逆時点回動自在となるようにカム部17若しくはこのカム部17（自転回動軸部16）と共に回動する部材と、カム係合部18若しくはこれと一体となる部材とに互いに突き合い係止するストッパー部20を設けている。   Further, in this embodiment, the cam portion 17 or the cam portion 17 (the rotation rotation shaft portion 16) is not rotated more than approximately 180 degrees so that the wiring is not hindered, and the cam portion 17 or the cam portion 17 can rotate freely in this range. In addition, a stopper portion 20 that abuts and engages with the rotating member and the cam engaging portion 18 or a member integrated therewith is provided.

また、本実施例では、前記係止部７が重合部４の自転回動と共に規制部８に対して自転回動し、重合部４の起伏回動と共に規制部８に対して公転回動するが、この係止部７を太鼓状や楕円状などの短径部と長径部とを有する平板形状や凹面形状とし、規制部８をこれを受ける凹状形状としている。この係止部７と規制部８の形状はこれに限らず様々に設計可能であるが、例えば係止部７を自転回転面に対して、長辺部と短辺部とを有する形状とした場合には、起伏回動軸部９と同軸である規制部形成部材８Ａの太径部間を凹設状態に設けて規制部８を形成するが、自転回動自在とすべき位置に係止部７が配されるときには、これを許容するように四方に十分な径を有する凹部形状とし、且つ所定自転回動向きで起伏回動を許容するため、起伏回動軸部９の回動方向に係止部７の公転移動（起伏回動）を許容する凹部形状とし、前記凹部空間とこの凹部空間とが連設するように形成し、この起伏回動を許容する連設凹部部分は、自転回動を阻止するため、短辺部より幅広いが長辺部より幅狭い形状としている。   Further, in this embodiment, the locking portion 7 rotates and rotates with respect to the restricting portion 8 with the rotation of the overlapping portion 4, and revolves with respect to the restricting portion 8 with the undulating rotation of the overlapping portion 4. However, the engaging portion 7 has a flat plate shape or a concave shape having a short diameter portion and a long diameter portion such as a drum shape or an elliptical shape, and the restriction portion 8 has a concave shape for receiving the same. The shape of the engaging portion 7 and the restricting portion 8 is not limited to this, and can be designed in various ways. For example, the engaging portion 7 has a long side portion and a short side portion with respect to the rotation surface. In this case, the restricting portion 8 is formed in a recessed state between the large diameter portions of the restricting portion forming member 8A that is coaxial with the undulating turning shaft portion 9, but is locked at a position where it should be able to rotate and rotate. When the portion 7 is arranged, a concave shape having a sufficient diameter on all four sides is allowed to allow this, and the rotation direction of the undulation rotation shaft portion 9 is allowed to allow the undulation rotation in a predetermined rotation rotation direction. The recess portion that allows the revolving movement (undulation rotation) of the locking portion 7 to the recess portion, the recess space and the recess space are formed so as to be connected to each other. In order to prevent rotation, the shape is wider than the short side but narrower than the long side.

また、別例（実施例２）としては、係止部７を下面が起伏回動軸部９を逃げる凹面形状として起伏回動に際して起伏回動軸部９を覆い配設しつつ起伏回動方向に移動できるようにし、且つこのときは自転回動が邪魔されて自転回動は阻止されるが、十分に起伏回動した位置では四方に広い凹部によって自転回動が阻止されないように構成するなど様々に設計可能である。   As another example (Embodiment 2), the engaging portion 7 is formed in a concave shape whose bottom surface escapes the undulating rotation shaft portion 9, and the undulating rotation shaft portion 9 is covered and disposed during the undulation rotation. In this case, the rotational rotation is obstructed and the rotational rotation is prevented. However, in the position where the undulation is sufficiently rotated, the rotational rotation is not prevented by the wide recesses on all sides. Various designs are possible.

即ち、例えば重合部４を９０度起伏回動するまでは重合部４は係止部７が規制部８に当たり干渉して自転回動できず、また、例えば本体部２と重合部４とを重合し得る捩れのない位置（０度，１８０度自動回動位置）では、規制部８内で起伏回動し、規制部８に干渉しないが、また例えば９０度重合部４を自転回動した位置では、係止部７が完全に規制部８に突き当たり略立ち起こし位置（本体部２と重合部４とが略直角となる回動位置）以上は閉塞回動できないように構成する。   That is, for example, until the overlapping portion 4 is swung up and down 90 degrees, the overlapping portion 4 cannot rotate due to the engaging portion 7 hitting the restricting portion 8 and cannot rotate, and for example, the main body portion 2 and the overlapping portion 4 are overlapped. At a position where there is no twist (0 degree, 180 degree automatic rotation position), the position is rotated up and down within the restricting portion 8 and does not interfere with the restricting portion 8, but also, for example, a position where the 90 degree overlapping portion 4 is rotated and rotated. Then, it is configured such that the locking portion 7 completely contacts the restricting portion 8 and cannot be closed and rotated beyond the substantially raised position (the rotation position where the main body portion 2 and the overlapping portion 4 are substantially perpendicular).

更に説明すれば、本実施例では、前記開閉回動ヒンジ部ＨＡによりカム係合による位置決めロックされた開放状態（並びに略立ち起こした位置に至るまでの開放状態にある回動位置）では、係止部７が規制部８に干渉することなく自由に１８０度正逆自転回動可能な状態となり、またカムロックしていた開放状態からの閉塞回動に際しては、係止部７の向きが起伏回動可能な状態にあり、また、開放状態で重合部４を自転回動して捩れた回動位置にある場合は、係止部７が規制部８に干渉して前記開放回動位置以上は閉塞回動できず、従って正しい重合向きでない場合には重合部４は閉塞回動できないように構成している。   More specifically, in this embodiment, in the open state in which the positioning is locked by the cam engagement by the opening / closing rotation hinge part HA (and the rotation position in the open state until reaching the substantially raised position), The stop portion 7 can freely rotate 180 degrees forward and reverse without interfering with the restricting portion 8, and the direction of the locking portion 7 undulates when closing and turning from the open state where the cam lock is performed. In the open state, when the overlapped portion 4 is rotated and rotated, the latching portion 7 interferes with the restricting portion 8 and the above-mentioned open rotation position or more Therefore, the overlapping portion 4 is configured so as not to be closed and rotated when it cannot be closed and rotated.

従って、捩れた状態で閉塞回動することも阻止され、また正しい向きで閉塞回動する途中で捩れた向きに自転回動することも阻止されるため、重合部４の端部角部が本体部２に突き当たることを防止でき、また本体部２上の操作部１を誤って押し操作することも防止できるように構成している。   Accordingly, the rotation of the closed portion in the twisted state is also prevented, and the rotation of the rotation in the twisted direction in the middle of the closed rotation in the correct direction is also prevented. It is configured so that it can be prevented from striking against the portion 2, and the operation portion 1 on the main body portion 2 can be prevented from being pushed by mistake.

また、規制部８の端部を所定形状に面取り設定することで、少し捩れた回動位置で重合部４を閉塞回動すると、前記規制部８の上端形状に沿って自動的に重合部４が正しい向きに修正自転回動して重合閉塞するように構成することもでき、また、前述のようにどの開放範囲まで自転回動可能とし、どのくらい捩れていたら、どの位置以上閉塞回動不能とするかも微妙に調整設定できることとなる。   Further, by chamfering the end portion of the restricting portion 8 to a predetermined shape, when the overlapping portion 4 is closed and rotated at a slightly twisted rotation position, the overlapping portion 4 is automatically aligned along the upper end shape of the restricting portion 8. Can be configured to rotate and rotate in the correct orientation and close the polymerization, and as described above, it can be rotated to any open range, and if it is twisted, it can be blocked and rotated beyond what position. Moreover, it will be possible to make fine adjustment settings.

従って、重合部４が捩れ位置にあるにもかかわらず重合部４を閉塞回動することで重合部４の端部角部が前述のように本体部２に接触することを容易に阻止でき、しかも、本実施例では、係止部７と規制部８との形状設定により前述のように回動規制することを容易に実現することができるため、この回動規制を様々なバリエーションに簡単に設計できることとなる。   Therefore, it is possible to easily prevent the end corner of the overlapping portion 4 from contacting the main body 2 as described above by closing and rotating the overlapping portion 4 even though the overlapping portion 4 is in the twisted position. In addition, in the present embodiment, it is possible to easily realize the rotation restriction as described above by setting the shapes of the locking portion 7 and the restriction portion 8, so that this rotation restriction can be easily made into various variations. It can be designed.

また、本実施例では、前述のように前記自転回動ヒンジ部ＨＡの前記軸取付部10内側へ突出する端部に、前記第二部材４の自転回動と共に自転回動し、且つ前記第二部材４の起伏回動により起伏回動する係止部７を設け、この係止部７の自転回動並びに起伏回動を規制する規制部８を前記軸取付部10の内側であってこの軸取付部10を回動自在に設けた前記開閉回動ヒンジ部ＨＡの起伏回動軸部９に設けるが、この規制部８は、前記回動軸部16の外面を所定形状に形成して起伏回動軸部９に一体形成する構成とせず、外面部を所定形状に形成した規制部形成部材８Ａに前記起伏回動軸部９を連結して別パーツによって起伏回動部９に前記規制部８を設けた構成としている。   Further, in the present embodiment, as described above, the second member 4 rotates and rotates at the end protruding to the inside of the shaft attachment portion 10 of the rotation rotation hinge portion HA, and the second rotation is performed. A locking portion 7 is provided to turn up and down by the up-and-down rotation of the two members 4. A restricting portion 8 that restricts the rotation and up-and-down rotation of the locking portion 7 is provided inside the shaft mounting portion 10. The shaft mounting portion 10 is provided on the undulating rotation shaft portion 9 of the opening / closing rotation hinge portion HA provided so as to be rotatable. The restricting portion 8 has an outer surface of the rotation shaft portion 16 formed in a predetermined shape. The undulation rotation shaft portion 9 is connected to a restriction portion forming member 8A having an outer surface formed in a predetermined shape without being integrally formed with the undulation rotation shaft portion 9, and the restriction is applied to the undulation rotation portion 9 by another part. The portion 8 is provided.

即ち、前記軸取付部10はコ字状部材とし、このコ字状部材の両脚部10Ａを前記起伏回動軸部９に回動自在に設けると共に、架設部10Ｂに前記自転回動軸部16を自転回動自在に設け、このコ字状の軸取付部10の内側の脚部10Ａ間に前記規制部形成部材８Ａを配設し、前記起伏回動軸部９を両脚部10Ａの軸支孔10Ｃに通して起伏回動軸部９に軸取付部10を回動自在に設けると共に、例えばこの起伏回動軸部９を前記規制部形成部材８Ａの軸連結孔８Ｂに貫通して連結して、前記規制部８を前記脚部10Ａ間にして起伏回動軸部９に設けた構成としても良い。   That is, the shaft mounting portion 10 is a U-shaped member, and both leg portions 10A of the U-shaped member are rotatably provided on the undulating rotation shaft portion 9, and the rotation rotation shaft portion 16 is provided on the erection portion 10B. Is provided such that the restricting portion forming member 8A is disposed between the leg portions 10A on the inner side of the U-shaped shaft mounting portion 10, and the undulating rotation shaft portion 9 is pivotally supported by both leg portions 10A. The shaft mounting portion 10 is rotatably provided on the undulating rotation shaft portion 9 through the hole 10C, and, for example, the undulating rotation shaft portion 9 is connected to the shaft connecting hole 8B of the restricting portion forming member 8A. The restricting portion 8 may be provided on the undulating rotation shaft portion 9 between the leg portions 10A.

従って、これまでの構成と異なり、起伏回動軸部９と規制部８とを別パーツとしたため、即ち、起伏回動軸部９の所定部分を所定形状に一体成形したり加工形成する構成とせず、起伏回動軸部９とは別パーツとして軸取付部10の脚部10Ａ間に配設する規制形成部材８Ａに起伏回動軸部９を貫通したり、起伏回動軸部９を側方から差し込み連結するなどして起伏回動軸部９と別体で設けた規制部形成部材８Ａに起伏回動軸部９を連結することで起伏回動軸部９に規制部８を設けた構成としたため、起伏回動軸部９は細く、規制部形成部材８Ａは大きく設計できる。これにより起伏回動軸部９は細いためこれまでどおり軸取付部10の脚部10Ａ（軸支孔10Ｃ）に挿通して起伏回動軸部９に軸取付部10を回動自在に設けることができる構成でありながら、たとえ規制部形成部材８Ａの外径を大きくしても脚部10Ａ（軸支孔10Ｃ）に規制部形成部材８Ａを通す必要はない構成のため、脚部10Ａを大きく（軸取付部10を大きく）しなくても大きな規制部形成部材８Ａ（深い凹部が形成可能な規制部形成部材８Ａ）を軸取付部10の内側に配することができ、しかも起伏回動軸部９と規制部形成部材８Ａとを連結するため、起伏回動軸部９にこれまでどおり規制部８を設けることができる。   Therefore, unlike the conventional configuration, the undulating rotation shaft portion 9 and the restricting portion 8 are separate parts, that is, the predetermined portion of the undulating rotation shaft portion 9 is integrally formed or processed into a predetermined shape. As a separate part from the undulating and rotating shaft part 9, the undulating and rotating shaft part 9 is passed through the restriction forming member 8A disposed between the leg parts 10A of the shaft mounting part 10 or the undulating and turning shaft part 9 is placed on the side. The restricting portion 8 is provided on the undulating rotation shaft portion 9 by connecting the undulating rotation shaft portion 9 to the restricting portion forming member 8A provided separately from the undulating rotation shaft portion 9 by being inserted and connected from the side. Since the configuration is such that the undulating rotation shaft portion 9 is thin, the restricting portion forming member 8A can be designed large. As a result, since the undulating rotation shaft portion 9 is thin, it is inserted into the leg portion 10A (the shaft support hole 10C) of the shaft mounting portion 10 as before, and the shaft mounting portion 10 is provided rotatably on the undulating rotation shaft portion 9. However, even if the outer diameter of the restricting portion forming member 8A is increased, it is not necessary to pass the restricting portion forming member 8A through the leg portion 10A (the shaft support hole 10C). A large restricting portion forming member 8A (a restricting portion forming member 8A capable of forming a deep concave portion) can be arranged inside the shaft attaching portion 10 without increasing the shaft attaching portion 10 and the shaft for rotating the undulations. In order to connect the part 9 and the restricting part forming member 8A, the restricting part 8 can be provided on the undulating rotation shaft part 9 as before.

そのため、従来どおりコンパクト化を図れる構成にして十分に深い凹部を規制部形成部材８Ａに形成でき、係止部７の回動を阻止する当たり面（段差面）を十分に高く形成でき、係止部７の回動を確実に阻止でき、耐久性にも秀れた画期的なヒンジ装置並びにヒンジ装置を用いた電子機器をこの簡易な改良によって容易に実現できることとなる。   Therefore, it is possible to form a sufficiently deep concave portion in the restricting portion forming member 8A with a configuration that can be made compact as in the past, and a contact surface (step surface) that prevents the locking portion 7 from rotating can be formed sufficiently high. The revolutionary hinge device and the electronic device using the hinge device that can reliably prevent the rotation of the portion 7 and have excellent durability can be easily realized by this simple improvement.

また、本実施例では、軸取付部10の脚部10Ａに配した規制部形成部材８Ａに、脚部10Ａの軸支孔10Ｃに挿通した起伏回動軸部９をこの規制部形成部材８Ａの軸連結孔８Ｂに貫通して起伏回動軸部９と規制部形成部材８Ａとを連結すると構成を説明したが、脚部10Ａ間に配する規制部形成部材８Ａに起伏回動軸部９を貫通する軸連結孔８Ｂを設けず、左右の脚部10Ａの軸支孔10Ｃに夫々通す起伏回動軸部９と差し込み連結する軸連結孔８Ｂを規制部形成部材８Ａの左右に設けて左右の起伏回動軸部９と中央の規制部形成部材８Ａとを連結して起伏回動軸部９に規制部８を設ける構成としても良い。この実施例では規制部形成部材８Ａには貫通孔が不要であり、そのため中心部に通し軸がないため、更にこの規制部形成部材８Ａには深い凹部を形成可能となり、それ故係止部７の当たり段差を一層高く（深く）設計でき、確実に係止部７を規制でき、耐久性にも極めて秀れた一層本発明の作用・効果が良好に発揮できるものとなる。本実施例はこのタイプを実施例１として図示している。   Further, in this embodiment, the restricting portion forming member 8A disposed on the leg portion 10A of the shaft attaching portion 10 is provided with the undulating rotation shaft portion 9 inserted through the shaft support hole 10C of the leg portion 10A. Although the configuration has been described in which the undulation rotation shaft portion 9 and the restriction portion forming member 8A are connected through the shaft connection hole 8B, the undulation rotation shaft portion 9 is provided on the restriction portion formation member 8A disposed between the leg portions 10A. The shaft connecting holes 8B that are inserted and connected to the undulating rotation shaft portions 9 that pass through the shaft supporting holes 10C of the left and right leg portions 10A are provided on the left and right sides of the restricting portion forming member 8A. It is good also as a structure which connects the raising / lowering rotation shaft part 9 and the control part formation member 8A of the center, and provides the restriction part 8 in the raising / lowering rotation shaft part 9. FIG. In this embodiment, the restricting portion forming member 8A does not require a through hole, and therefore there is no through shaft in the center portion. Therefore, a deep recess can be formed in the restricting portion forming member 8A. The hitting step can be designed to be higher (deeper), the locking portion 7 can be reliably controlled, and the functions and effects of the present invention with excellent durability can be exhibited well. This example illustrates this type as Example 1.

また、本実施例では、前記開閉回動ヒンジ部ＨＡの前記起伏回動軸部９若しくはこの起伏回動軸部９の軸方向に設ける部材、前記第一部材２に設ける回路部と前記第二部材４に設ける回路部とを電気接続する配線21を巻回する配線巻回部22を設けている。   In the present embodiment, the undulation rotation shaft portion 9 of the opening / closing rotation hinge portion HA or the member provided in the axial direction of the undulation rotation shaft portion 9, the circuit portion provided in the first member 2, and the second A wiring winding part 22 for winding a wiring 21 that electrically connects a circuit part provided in the member 4 is provided.

即ち、前記開閉回動ヒンジ部ＨＡの起伏回動軸部９の一部若しくはこの軸方向に設けた部分であって前記規制部８の側方部に、外周部に前記配線21の巻回スペースが確保される部分を形成して前記配線巻回部22を設けている。   That is, a part of the undulation rotation shaft portion 9 of the opening / closing rotation hinge portion HA or a portion provided in this axial direction, on a side portion of the restriction portion 8, and on the outer periphery of the winding space of the wiring 21 The wiring winding part 22 is provided so as to form a part where the resistance is secured.

具体的には、前記ベース部10のカム係合ロック機構（筒状ケース12）を設けた側と反対側に延長した起伏回動軸部９を第一部材２に係合するが、この反対側は単に起伏回動軸部９を延長するだけの構成、即ち、延長した軸部にはカム係合機構は設けず、この延長した部分（起伏回動軸部９の一部）を配線巻回部22としている。   Specifically, the undulating rotation shaft portion 9 extended to the opposite side to the side where the cam engaging lock mechanism (cylindrical case 12) of the base portion 10 is provided is engaged with the first member 2, but this is not the case. The side is simply configured to extend the undulating rotation shaft portion 9, that is, the extended shaft portion is not provided with a cam engagement mechanism, and this extended portion (a part of the undulating rotation shaft portion 9) is wound by wiring. It is referred to as round part 22.

即ち、本実施例では、起伏回動軸部９の片側には、配線21、具体的にはフレキシブル配線を数回巻回固定保持する巻回部分としての配線巻回部22を設けている。また一方、前記自転回動ヒンジ部ＨＢの前記自転回動軸部16にも、前記第一部材２に設ける回路部と前記第二部材４に設ける回路部とを電気接続する配線21を巻回する配線巻回部22を設けている。   In other words, in this embodiment, a wiring winding portion 22 is provided on one side of the undulating rotation shaft portion 9 as a winding portion for fixing and holding the wiring 21, specifically, the flexible wiring several times. On the other hand, a wire 21 that electrically connects the circuit portion provided in the first member 2 and the circuit portion provided in the second member 4 is also wound around the rotation rotation shaft portion 16 of the rotation rotation hinge portion HB. A wiring winding part 22 is provided.

即ち、自転回動軸部16に巻回用リング23を被嵌し、これも配線巻回部22としている。従って、本発明は、このような開閉動作や規制動作に支障をきたすことなく、容易に配線することができる。   That is, the winding ring 23 is fitted on the rotation rotation shaft portion 16, and this is also used as the wire winding portion 22. Therefore, the present invention can be easily wired without hindering such an opening / closing operation and a regulating operation.

このような構成において、本実施例では、係止部７及び規制部８の形状を、前記第一部材２（本体部２）に対する前記第二部材４（重合部４）の起伏回動によって前記規制部８に対して前記係止部７が起伏回動する際、前記係止部７が前記規制部８に突き当たって係止部７の過回動が阻止されて前記重合部４の起伏回動における最大開放位置が規制され、且つ重合部４を１８０度自転回動して係止部７が１８０度自転回動した状態では起伏回動における最大開放位置ではまだ係止部７は規制部８に突き当たらず、前記重合部４の反転時の最大開放角度が反転前よりも増大する形状に設定している。即ち、重合部４を起伏回動して前記係止部７を起伏回動した際、最大開放位置で前記係止部７の底面が突き当たる前記規制部８の起伏回動阻止外面に凸部30を設け、この凸部30に前記係止部７の底面が突き当たることで係止部７の過回動が阻止されて、この係止部７が規制部８に突き当たる回動位置が前記第二部材４の最大開放位置となるように構成し、重合部４を１８０度自転回動して前記規制部８に対して前記係止部７が前記規制部８に対して１８０度自転回動した状態においてはこの係止部７を起伏回動した際、前記凸部30に係合する位置の前記係止部７の底面に凹部31を設け、この凸部30に凹部31が係合することで前記起伏回動における最大開放位置の開放回動角度が反転前より反転後の方が増大するように構成している。   In such a configuration, in the present embodiment, the shape of the locking portion 7 and the restricting portion 8 is changed by the undulating rotation of the second member 4 (overlapping portion 4) with respect to the first member 2 (main body portion 2). When the locking part 7 is swung up and down with respect to the restricting part 8, the locking part 7 hits the restricting part 8, and the overturning of the locking part 7 is prevented, and the overlapping part 4 is turned up and down. In the state where the maximum opening position in movement is restricted and the overlapping portion 4 is rotated 180 degrees and the locking portion 7 is rotated 180 degrees, the locking portion 7 is still in the maximum opening position in the undulation rotation. The maximum opening angle at the time of reversal of the overlapping portion 4 is set to be larger than that before reversal. That is, when the overlapping portion 4 is swung up and down and the locking portion 7 is swung up and down, the convex portion 30 is formed on the hulling and rotation preventing outer surface of the restricting portion 8 where the bottom surface of the locking portion 7 abuts at the maximum open position. When the bottom surface of the locking portion 7 abuts against the convex portion 30, excessive rotation of the locking portion 7 is prevented, and the rotation position where the locking portion 7 abuts against the restriction portion 8 is the second position. The overlapping portion 4 is rotated by 180 degrees and the locking portion 7 is rotated by 180 degrees with respect to the restricting portion 8. In this state, when the locking portion 7 is swung up and down, a recess 31 is provided on the bottom surface of the locking portion 7 at a position where the locking portion 7 is engaged, and the recess 31 is engaged with the protrusion 30. Thus, the opening rotation angle at the maximum opening position in the undulation rotation is configured to increase after reversal than before reversal.

本実施例１においては、この点前記起伏回動における最大開放位置での最大開放角度は凸部30によって約１６５度程度となるように設定し、重合部４を反転した際には凸部30を凹部31で逃げることで前記最大開放角度は増大して略１８０度となるように設定している。即ち、前記係止部７の底面の片側は平坦面として前記規制部８に対して前記係止部７が起伏回動時にこの平坦面が前記規制部８の起伏回動阻止外面に設けた凸部30に突き当たるように構成し、前記係止部７の底面の反対側には前記凸部30が係合する（逃げる）前記凹部31を設け、重合部４を反転して係止部７が１８０度自転回動した状態では、この凸部30と凹部31とが係合すると共に、凹部31の凹底面が前記凸部30に突き当たり若しくはこの凹部31の周辺が前記凸部30の周辺に突き当たって第二部材４の最大起伏回動位置の開放角度が増大して略１８０度まで開放可能となるように構成している。   In the first embodiment, the maximum opening angle at the maximum opening position in the above-described undulation rotation is set to be about 165 degrees by the convex portion 30. When the overlapping portion 4 is inverted, the convex portion 30 is reversed. The maximum opening angle is set to be approximately 180 degrees by escaping through the recess 31. That is, one side of the bottom surface of the locking portion 7 is a flat surface, and this flat surface is provided on the outer surface of the restriction portion 8 that prevents the rotation of the locking portion 7 when the locking portion 7 is swung with respect to the restriction portion 8. The concave portion 31 is provided on the opposite side of the bottom surface of the locking portion 7 so that the convex portion 30 engages (displaces), and the overlapping portion 4 is reversed to form the locking portion 7. In the state of rotating 180 degrees, the convex portion 30 and the concave portion 31 are engaged with each other, and the concave bottom surface of the concave portion 31 hits the convex portion 30 or the periphery of the concave portion 31 hits the periphery of the convex portion 30. Thus, the opening angle of the maximum undulation rotation position of the second member 4 is increased so that it can be opened up to about 180 degrees.

また、実施例２では、係止部７の底面が規制部８を逃げる湾曲状に形成して規制部８に対して起伏回動（公転移動）を許容する形状とした実施例で、この場合係止部７の端部が規制部８の起伏回動阻止外面に突き出るように設定して最大開放角度を規制するようにし、この係止部７の両端部の中心からの長さを異ならせて係止部７を反転したときこの突き当たるまでの起伏回動許容範囲を異ならせて反転時の起伏回動における最大開放角度が１６０〜１７０度程度から略１８０度まで開放回動可能となり最大開放角度は反転前に比して反転後の方が増大するように構成している。   Further, in the second embodiment, the bottom surface of the locking portion 7 is formed in a curved shape that escapes the restricting portion 8, and has a shape that allows undulation rotation (revolution movement) with respect to the restricting portion 8. The maximum opening angle is regulated by setting the end of the locking part 7 to protrude from the undulation rotation preventing outer surface of the regulating part 8, and the lengths from the centers of both ends of the locking part 7 are made different. When the locking portion 7 is reversed, the allowable range of undulation rotation until the abutment is made different so that the maximum opening angle in the undulation rotation at the time of reversal can be opened and rotated from about 160 to 170 degrees to about 180 degrees, and the maximum opening is possible. The angle is configured to increase after inversion compared to before inversion.
