Description

本発明は、ヒンジ装置並びに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 and an electronic apparatus 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 superposition part on the upper side, this main part and superposition part are connected via a hinge device, and the main part and superposition part are folded in half and operated From the folded closed state in which the portion is concealed by the overlapping portion, the overlapping portion is turned upside down by the hinge device and reversed to be switched to an open state in which the operation portion and the display portion are exposed.

そのため、従来のこのような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。   Therefore, in a conventional electronic device that covers the operation part of the main body part with such a undulating and rotating superposition part, it can be folded and compactized, but the display part is also concealed in a superposition state where the operation part is concealed In many cases, use in a compact state is inevitably restricted.

また、操作部を操作する場合には、ディスプレイ部を設けた重い重合部を立ち起こし反転回動させなければならず、この開閉動作（特に開放動作）させずらい欠点もある（近年、カメラ機構を具備した機種が益々増える中、この重合部は重くなる傾向にある。）。   In addition, when operating the operation unit, it is necessary to raise and turn the heavy overlapping unit provided with the display unit, and there is a drawback that it is difficult to perform this opening / closing operation (especially the opening operation) (in recent years, the camera mechanism). As the number of models equipped with more and more, this superposition part tends to become heavy.)

そこで、起伏回動により開閉動作するのではなく、重合面に沿って略水平方向に重合部を回動して開閉動作するように構成し、例えば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、ディスプレイ部が上側に配設され、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り、また重合してコンパクト化した状態から操作部及びディスプレイ部を露出して本体部と重合部とを連設した状態に切り替える場合は、重合面に沿って略水平方向に重合部を回動することで行えるため、この開放動作も容易に行え、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る携帯電話，モバイル等の電子機器が提案されている。   Therefore, instead of opening and closing by rolling up and down, it is configured to open and close by rotating the overlapping part in a substantially horizontal direction along the overlapping surface, for example, folded when not in use or requiring no key operation Even in other words, even in a compact state where the operation unit is concealed by superimposing the overlapped part provided with the display part on the main body part, the display part is arranged on the upper side so that the display part can be seen or functioned. In addition, when switching from a superposed and compacted state to a state in which the operation unit and the display unit are exposed and the main body unit and the superposed unit are connected, the horizontal direction along the superposition surface Since it can be performed by rotating the overlapping portion, this opening operation can be easily performed, and the usage can be expanded as a device and the opening / closing operation can be easily performed. Electronic devices and the like have been proposed.

本出願人は、このような例えば水平回動タイプの電子機器の実用性を向上するために試行錯誤を重ねた結果、極めて商品価値の高い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開発した。   As a result of repeated trial and error in order to improve the practicality of such an electronic device of, for example, the horizontal rotation type, the applicant of the present invention has achieved a revolutionary hinge device with extremely high commercial value and an electronic device using the hinge device. Developed.

好適と考える本発明の最良の形態（発明をどのように実施するのが最良か）を、図面に基づいて本発明の作用効果を示して簡単に説明する。   BEST MODE FOR CARRYING OUT THE INVENTION The best mode of the present invention considered to be suitable (how best to carry out the invention) will be briefly described with reference to the drawings showing the effects of the present invention.

例えば操作部14を設けた本体部と、ディスプレイ部15を設けた重合部とを、前記操作部14を操作しない時にはこの操作部14を覆うように重合配設し、この重合した状態から前記重合部を相対的に水平回動して操作部14を露出させることができるように、前記本体部と重合部とを回動自在に連結するヒンジ装置として本発明を適用させた場合、具体的には、例えば第二部材２を操作部14を設けた本体部とし、第一部材１をディスプレイ部15を設けた重合部とすれば、このヒンジ装置により端部同志を重合して連結することで、本体部２に対して重合部１を略水平方向に回動自在に連結でき、前記操作部14を操作しない時にはコンパクト化するため、この操作部14を覆うように本体部２と重合部１とを上下に重合配設し、また、このコンパクト化された重合状態では、ディスプレイ部15は重合部１の上面側に配されているため、操作部14は操作できないにしてもディスプレイ部15を視認することができ、またディスプレイ部15を機能させるように構成すれば、例えば予め操作部14により設定するなどした日付やカレンダー表示をさせたり、またデータ通信表示（携帯電話では例えば着信表示など）を行うようにしたりすれば、ディスプレイ部15は視認できるため様々な使用が可能となり、使用用途が広がったり、機能性が向上し、非常に便利となり実用性（商品価値）が高まる。   For example, a main body provided with the operation unit 14 and a superposition unit provided with the display unit 15 are arranged so as to cover the operation unit 14 when the operation unit 14 is not operated. When the present invention is applied as a hinge device that pivotally connects the main body portion and the overlapping portion so that the operation portion 14 can be exposed by relatively rotating the portion horizontally, specifically, For example, if the second member 2 is a main body provided with an operation part 14 and the first member 1 is a superposition part provided with a display part 15, the end devices are superposed and connected by this hinge device. The superposition part 1 can be connected to the main body part 2 so as to be rotatable in a substantially horizontal direction. When the operation part 14 is not operated, the main body part 2 and the superposition part 1 are covered so as to cover the operation part 14 for compactness. The top and bottom are arranged in a superposition, and this compact In the combined state, since the display unit 15 is arranged on the upper surface side of the overlapping unit 1, the display unit 15 can be visually recognized even if the operation unit 14 cannot be operated, and the display unit 15 is configured to function. If, for example, the date or calendar displayed by the operation unit 14 is displayed in advance, or if data communication display (for example, incoming call display on a mobile phone) is performed, the display unit 15 can be visually recognized. Can be used in a wide range of applications, and the usage can be expanded and functionality can be improved.

ところで、本発明は、本体部２の操作部14を露出させるに際し、本体部２に対して重合部１を所定の位置まで水平回動させると、その後は、本体部２に対して重合部１が自動で水平回動して本体部２の操作部14が露出することになる。   By the way, in the present invention, when the operation unit 14 of the main body 2 is exposed, if the superposition unit 1 is horizontally rotated to a predetermined position with respect to the main body 2, then the superposition unit 1 with respect to the main body 2. Is automatically rotated horizontally, and the operation unit 14 of the main body 2 is exposed.

具体的には、重合部１（第一部材）と本体部２（第二部材）とを相対回動して一の回動位置Ｐ１でカム部８とカム係合部10とが係合付勢されて凹凸係合し、係合付勢機構11によりこの係合が保持される或いは係合付勢されるように構成し、このカム部８，カム係合部10のいずれか一方を係合付勢機構11に抗して離反方向に移動させつつ回動させることでカム係合部10若しくはカム部８に設けた凹部９に対してカム部８若しくはカム係合部10に設けた凸部７を係脱させた際に、このカム部８若しくはカム係合部10に設けた凸部７が滑動する下り面部12をカム係合部10若しくはカム部８に設けて、重合部１と本体部２とを一の回動位置Ｐ１と異なる他の回動位置Ｐ２まで相対回動せしめる自動回動付勢が生じるように構成している。   Specifically, the overlapping portion 1 (first member) and the main body portion 2 (second member) are relatively rotated so that the cam portion 8 and the cam engagement portion 10 are engaged at one rotation position P1. It is configured so that the engagement is uneven and the engagement is maintained or the engagement is biased by the engagement biasing mechanism 11, and either the cam portion 8 or the cam engagement portion 10 is engaged. Convex provided on the cam part 8 or the cam engaging part 10 with respect to the concave part 9 provided on the cam engaging part 10 or the cam part 8 by rotating while moving in the separating direction against the urging mechanism 11 When the cam part 8 is disengaged, the cam part 8 or the cam engaging part 10 is provided with a descending surface part 12 on which the convex part 7 provided on the cam engaging part 10 or the cam part 8 slides. An automatic rotation urging force that causes the main body 2 to rotate relative to another rotation position P2 different from the one rotation position P1 is generated.

つまり、カム部８若しくはカム係合部10に設けた凸部７がカム係合部10若しくはカム部８に設けた凹部９に凹凸係合する、一の回動位置Ｐ１に位置する際に重合部１が本体部２に対して重合する状態とした場合、重合部１を本体部２に対して回動させることで前記凹部９から前記凸部７を係脱させた際、この凸部７はカム係合部10若しくはカム部８に設けた下り面部12を滑動することで生じる自動回動付勢により、重合部１は本体部２に対して一の回動位置Ｐ１と異なる他の回動位置Ｐ２まで自動で水平回動して本体部２の操作部14が露出することになる。   That is, when the convex portion 7 provided on the cam portion 8 or the cam engaging portion 10 engages with the concave portion 9 provided on the cam engaging portion 10 or the cam portion 8 and is positioned at one rotation position P1, it is overlapped. When the part 1 is in a state of being superposed on the main body part 2, when the convex part 7 is disengaged from the concave part 9 by rotating the superposed part 1 relative to the main body part 2, the convex part 7 The overlapping portion 1 is different from the one rotation position P1 with respect to the main body portion 2 by the automatic turning bias generated by sliding the descending surface portion 12 provided on the cam engaging portion 10 or the cam portion 8. The operation part 14 of the main body 2 is exposed by automatically turning horizontally to the moving position P2.

従って、従来から提案されるヒンジ装置であれば重合状態から露出状態となるまで、例えば本体部２を持つ手と反対の手で該本体部２の操作部が露出する状態となるまで重合部１を回動することになるが、この点、本発明によれば、例えば本体部２を持つ手の指で重合部１を所定位置まで水平回動させるだけで、その後は重合部１は本体部２の操作部が露出する状態となるまで自動で水平回動することになり、非常に操作性に秀れて便利である。また、再び重合部１によって本体部の操作部を隠蔽する状態とする際には、手などを利用して、凸部７が凹部９に凹凸係合する位置まで本体部２に対して重合部１を水平回動させることになる。   Therefore, in the case of a conventionally proposed hinge device, the overlapping portion 1 is changed from the overlapped state to the exposed state, for example, until the operation portion of the main body portion 2 is exposed with the hand opposite to the hand having the main body portion 2. In this respect, according to the present invention, for example, the overlapping portion 1 is simply rotated horizontally to a predetermined position with a finger of a hand having the main body portion 2. It will automatically rotate horizontally until the operation part 2 is exposed, which is very convenient and excellent in operability. Further, when the operation unit of the main body is concealed again by the superimposing unit 1, the superposed unit with respect to the main body 2 to the position where the convex portion 7 engages with the concave portion 9 by using a hand or the like. 1 is rotated horizontally.

また、本発明は、カム部８に複数の凸部７を設け、この各凸部７が凹凸係合する複数の凹部９をカム係合部10に設け、各凹部９に対してカム部８に設けた各凸部７を係脱させた際に、このカム部８に設けた各凸部７が滑動する複数の下り面部12をカム係合部10に設けている。   Further, according to the present invention, a plurality of convex portions 7 are provided in the cam portion 8, and a plurality of concave portions 9 in which the convex portions 7 engage with each other are provided in the cam engaging portion 10. The cam engaging portion 10 is provided with a plurality of descending surface portions 12 on which the convex portions 7 provided on the cam portion 8 slide when the convex portions 7 provided on the cam portion 8 are engaged and disengaged.

これは、第一部材１と第二部材２との円滑な相対回動が行われることに貢献する。   This contributes to smooth relative rotation between the first member 1 and the second member 2.

即ち、例えばカム係合部10に設ける凹部９に凹凸係合し且つ下り面部12に対して滑動するカム部８に設ける凸部７が一つで構成されている場合、この一つの凸部７が下り面部12を滑動する際、１点支持となる１箇所当接状態（所謂片持ち状態）となる為、回動軸部４を介して相対回動するカム部８，カム係合部10同志間に傾斜方向に力が掛かってしまい、つまり、相対回動する回動軸部４，軸受部６同志間に偏荷重が掛かってしまい、この場合、部品同士の磨耗によるガタつきの問題や、回動軸部４の回動が良好に行われず自動回動付勢が上手く機能しない問題など、種々の問題が生じてしまうことが懸念される。   That is, for example, when the convex portion 7 provided in the cam portion 8 that engages with the concave portion 9 provided in the cam engaging portion 10 and slides with respect to the descending surface portion 12 is constituted by one, this single convex portion 7. Is in a one-point contact state (so-called cantilever state) that is supported at one point when sliding down the descending surface portion 12, the cam portion 8 and the cam engagement portion 10 that rotate relative to each other via the rotation shaft portion 4. A force is applied in an inclined direction between the two members, that is, an eccentric load is applied between the rotating shaft portion 4 and the bearing portion 6 that rotate relative to each other, and in this case, a problem of looseness due to wear between components, There is a concern that various problems may occur, such as the problem that the rotation of the rotation shaft 4 is not performed well and the automatic rotation bias does not function well.

この点、本発明は、カム部８に設ける凸部７、カム係合部10に設ける凹部９，下り面部12夫々は複数設けられている為、前記カム部８とカム係合部10を相対回動させた際、各凹部９から係脱した各凸部７が、同時に各下り面部12を複数箇所当接状態で滑動することになるから、それだけ安定した状態が得られることになり、よって、回動軸部４を介して相対回動するカム部８，カム係合部10同志間に前述したような傾斜方向に力が掛かってしまうのを防止することができ、相対回動する回動軸部４，軸受部６同志間に偏荷重が生じることは可及的に防止されることになる。   In this respect, the present invention has a plurality of convex portions 7 provided on the cam portion 8, concave portions 9 provided on the cam engaging portion 10, and a descending surface portion 12, so that the cam portion 8 and the cam engaging portion 10 are relative to each other. Since each convex part 7 engaged / disengaged from each concave part 9 will slide at the same time in a state where a plurality of descending surface parts 12 are in contact with each other at the time of rotation, a more stable state can be obtained. Thus, it is possible to prevent a force from being applied in the inclined direction as described above between the cam portion 8 and the cam engaging portion 10 that rotate relative to each other via the rotation shaft portion 4, and to rotate relative to each other. It is possible to prevent as much as possible that an uneven load is generated between the moving shaft portion 4 and the bearing portion 6.

また、本発明は、カム部８，カム係合部10のいずれか一方を係合付勢機構11に抗して離反方向に移動させつつ左右いずれか一方向に相対回動させることで、前記第一凹部９Ａ，第二凹部９Ｂに対して第一凸部７Ａ，第二凸部７Ｂを係脱させた際に、この第一凸部７Ａ，第二凸部７Ｂが前記係合付勢機構11の付勢を伴い滑動する第一下り面部12Ａ，第二下り面部12Ｂを前記突合せ端部４Ａ若しくは軸受孔開口端部６Ａの同一円周上でない位置に設けるとともに、カム部８，カム係合部10のいずれか一方を係合付勢機構11に抗して離反方向に移動させつつ左右いずれか他方向に相対回動させることで、前記第一凹部９Ａ，第二凹部９Ｂに対して第一凸部７Ａ，第二凸部７Ｂを係脱させた際に、この第一凸部７Ａ，第二凸部７Ｂが前記係合付勢機構11の付勢を伴い滑動する第三下り面部12Ｃ，第四下り面部12Ｄを前記突合せ端部４Ａ若しくは軸受孔開口端部６Ａの同一円周上でない位置に設けて、第一部材１と第二部材２とを前記一の回動位置Ｐ１と異なる他の回動位置Ｐ２まで相対回動せしめる自動回動付勢が生じるように構成している。In addition, the present invention is configured such that either one of the cam portion 8 and the cam engagement portion 10 is relatively rotated in either the left or right direction while being moved in the separation direction against the engagement biasing mechanism 11. When the first convex portion 7A and the second convex portion 7B are engaged with and disengaged from the first concave portion 9A and the second concave portion 9B, the first convex portion 7A and the second convex portion 7B are engaged with the engagement biasing mechanism. The first descending surface portion 12A and the second descending surface portion 12B that slide with 11 biasing are provided at positions not on the same circumference of the butted end portion 4A or the bearing hole opening end portion 6A, and the cam portion 8 and cam engagement One of the parts 10 is moved relative to the left and right other directions while moving in the separation direction against the engagement urging mechanism 11, thereby making the first recess 9A and the second recess 9B When the first convex portion 7A and the second convex portion 7B are engaged and disengaged, the first convex portion 7A and the second convex portion 7B are attached to the engagement biasing mechanism 11. A third descending surface portion 12C and a fourth descending surface portion 12D that slide with force are provided at positions that are not on the same circumference of the butted end portion 4A or the bearing hole opening end portion 6A. Is configured so as to generate an automatic rotation bias that relatively rotates to another rotation position P2 different from the one rotation position P1.

When the state of overlapping with the part 2 (the state in which the operation part 14 is concealed) is defined as one rotation position P1, the overlapping part 1 is manually rotated in either the left or right direction with respect to the main body part 2. Thus, when the first convex portion 7A and the second convex portion 7B are engaged and disengaged from the first concave portion 9A and the second concave portion 9B by rotating to a predetermined rotational position, the first convex portion 7A, When the second convex portion 7B slides down the first descending surface portion 12A, the second descending surface portion 12B or the third descending surface portion 12C, and the fourth descending surface portion 12D provided in the cam engaging portion 10, an automatic rotation bias is generated. Therefore, the overlapping portion 1 is automatically opened from the one rotation position P1 to the other rotation position P2 within a rotation range of 180 ° with respect to the main body portion 2. The operation part 14 of the main body 2 is exposed by horizontally turning in the release direction.

In this case, the descending surface portion 12 only needs to have a first descending surface portion 12A and a second descending surface portion 12B. The two convex portions 7B, the first concave portion 9A, the second concave portion 9B, the first descending surface portion 12A, and the second descending surface portion 12B are on the same circumference as long as they are at the left and right opposing positions with the rotating shaft portion 4 interposed therebetween. (Of course, it may not be on the same circumference).

以上の構成から、本実施例は、水平回動自在に連結される本体部２と重合部１との枢着部に組み付けた際、本体部２に対して重合部１が重合状態となる一の回動位置Ｐ１から、該重合部１を左右いずれかの方向に水平回動させた際、回動位置Ｐ３若しくは回動位置Ｐ４を過ぎるまでは、係合付勢機構11の係合付勢を伴うカム部８の第一凸部７Ａ，第二凸部７Ｂとカム係合部10の第一凹部９Ａ，第二凹部９Ｂとの凹凸係合により重合部１を回動位置Ｐ１まで自動で閉塞方向に回動させるように構成され、一方、この回動位置Ｐ３若しくは回動位置Ｐ４を過ぎれば、第一凸部７Ａ，第二凸部７Ｂが、係合付勢機構11の付勢（押圧力）を伴って第一下り面部12Ａ，第二下り面部12Ｂ若しくは第三下り面部12Ｃ，第四下り面部12Ｄを滑動することにより重合部１を回動位置Ｐ２まで自動で開放方向に回動させるように構成されている（図12参照）。   From the above configuration, in the present embodiment, the superposed portion 1 is in a superposed state with respect to the main body portion 2 when assembled to the pivot portion of the main body portion 2 and the superposed portion 1 that are connected so as to be horizontally rotatable. When the overlapping portion 1 is horizontally rotated in either the left or right direction from the rotation position P1, the engagement urging mechanism 11 is engaged until the rotation position P3 or the rotation position P4 is passed. With the concave and convex engagement of the first convex portion 7A and the second convex portion 7B of the cam portion 8 with the first concave portion 9A and the second concave portion 9B of the cam engaging portion 10, the overlapping portion 1 is automatically moved to the rotation position P1. On the other hand, when the rotation position P3 or the rotation position P4 is passed, the first convex portion 7A and the second convex portion 7B are biased by the engagement biasing mechanism 11 ( By sliding the first descending surface portion 12A, the second descending surface portion 12B or the third descending surface portion 12C, and the fourth descending surface portion 12D with a pressing force). It is configured to rotate in the opening direction by automatically part 1 to rotate the position P2 (see FIG. 12).

また、本実施例は、本体部２に対する重合部１の相対過回動を阻止する過回動阻止機構17が設けられており、この過回動阻止機構17は、本体部２に対して重合部１を重合した状態から左右いずれの方向に相対回動させた際においても、重合部１が本体部２と直線状に連設状態となる同一位相位置Ｐ２で相対過回動が阻止されるように構成されている（図12参照）。   In this embodiment, an over-rotation prevention mechanism 17 that prevents relative over-rotation of the overlapping portion 1 with respect to the main body portion 2 is provided. When the part 1 is relatively rotated in the left or right direction from the overlapped state, the relative overturning is prevented at the same phase position P2 where the overlapping part 1 is linearly connected to the main body part 2. (See FIG. 12).

具体的には、この過回動阻止機構17は、第一連結部３に一体成形され、第二連結部５上で相対回動自在に連設される円筒状のストッパー部18を設け、このストッパー部18に対して左右いずれの方向にも相対回動自在となる環状の被嵌部材19を被嵌連結しており、このストッパー部18と被嵌部材19との間に、ストッパー部18が左右いずれの方向に回動しても突き当たり係止することで被嵌部材19が共に左右方向に共同回動することとなる第一突き当たり係止機構20を設けるとともに、このストッパー部18と被嵌部材19とが共に左右いずれの方向に共同回動した際においても、この共同回動を突き当たり係止により阻止する第二突き当たり係止機構21を、被嵌部材19と第二連結部５とに設けて構成されている。   Specifically, the over-rotation preventing mechanism 17 is integrally formed with the first connecting portion 3 and is provided with a cylindrical stopper portion 18 that is connected to the second connecting portion 5 so as to be relatively rotatable. An annular fitting member 19 that is rotatable relative to the stopper portion 18 in either the left or right direction is fitted and connected, and the stopper portion 18 is interposed between the stopper portion 18 and the fitting member 19. In addition to providing a first abutment locking mechanism 20 that allows the fitted member 19 to co-rotate in the left-right direction by locking against each other regardless of whether it rotates in the left or right direction, Even when the member 19 is jointly rotated in either the left or right direction, the second abutting locking mechanism 21 that prevents the joint rotation by abutting locking is provided between the fitted member 19 and the second connecting portion 5. It is provided and configured.

更に具体的に説明すると、前記第一突き当たり係止機構20は、ストッパー部18が左右夫々の方向に回動した際、被嵌部材19の一端縁（上端縁）に突設された第一係止部22の左右側部夫々に突き当たり係止する第一突き当たり部23をストッパー部18に突設しており、ストッパー部18を右方向に回動させることで、この第一突き当たり部23の一の側部23ａが第一係止部22の一の側部22ａに突き当たり係止することで、ストッパー部18と被嵌部材19とが共に右方向に共同回動し、反対に、ストッパー部18を左方向に回動させることで、この第一突き当たり部23は略一周した後、該第一突き当たり部23の他の側部23ｂが第一係止部22の他の側部22ｂに突き当たり係止することで、ストッパー部18と被嵌部材19とが共に左方向に共同回動し得るように設けて構成されている。   More specifically, the first abutment locking mechanism 20 includes a first engagement member that protrudes from one end edge (upper edge) of the fitted member 19 when the stopper portion 18 rotates in the left and right directions. A first abutting portion 23 that abuts and locks to the left and right side portions of the stop portion 22 is provided on the stopper portion 18, and one of the first abutting portions 23 is formed by rotating the stopper portion 18 to the right. When the side portion 23a of the first locking portion 22 abuts and locks against one side portion 22a of the first locking portion 22, both the stopper portion 18 and the fitted member 19 rotate together in the right direction, and conversely, the stopper portion 18 The first abutting portion 23 is rotated substantially to the left so that the other side portion 23b of the first abutting portion 23 abuts against the other side portion 22b of the first locking portion 22. By stopping, the stopper portion 18 and the fitted member 19 are both provided and configured to be able to rotate together in the left direction. That.

この第一突き当たり係止機構20により、ストッパー部材18と被嵌部材19とが共に右方向に共同回動した際、被嵌部材19の他端縁（下端縁）に突設された第二係止部24の一の側部24ａに突き当たり係止してその共同回動を阻止する第二突き当たり部25を第二連結部５の上面に突設すると共に、反対に、ストッパー部材18と被嵌部材19とが共に左方向に共同回動した際、被嵌部材19に設けられた第二係止部24の他の側部24ｂに突き当たり係止してその共同回動を阻止する第三突き当たり部26を第二連結部５の上面にして前記第二突き当たり部25と所定間隔Ｓを介した位置に突設して前記第二突き当たり係止機構21は構成されている（図６，７参照）。   When the stopper member 18 and the fitted member 19 are both rotated together in the right direction by the first abutment locking mechanism 20, the second engagement is provided at the other end (lower end edge) of the fitted member 19. A second abutting portion 25 that abuts and locks against one side portion 24a of the stopping portion 24 to prevent its joint rotation protrudes from the upper surface of the second connecting portion 5, and on the contrary, is fitted to the stopper member 18 When the member 19 and the member 19 are jointly rotated in the left direction, the third abutment that abuts and locks against the other side 24b of the second engaging portion 24 provided on the fitted member 19 to prevent the joint rotation. The second abutting locking mechanism 21 is configured with the portion 26 as an upper surface of the second connecting portion 5 and projecting at a position via the second abutting portion 25 and a predetermined distance S (see FIGS. 6 and 7). ).

また、この過回動阻止機構17を構成する第一突き当たり係止機構20と第二突き当たり係止機構21とは、第二連結部５に対して第一連結部３を左方向に相対回動させた際、第一連結部３に設けた第一突き当たり部23が回動停止する位置と、第二連結部５に対して第一連結部３を右方向に相対回動させた際、第一連結部３に設けた第一突き当たり部23が回動停止する位置とが同一位置となるように構成されている（図12参照）。   Further, the first abutting locking mechanism 20 and the second abutting locking mechanism 21 constituting the over-rotation preventing mechanism 17 relatively rotate the first connecting portion 3 in the left direction with respect to the second connecting portion 5. When the first connecting portion 3 provided in the first connecting portion 3 is rotated and stopped relative to the position where the first abutting portion 23 is stopped and the second connecting portion 5 is rotated to the right. The position where the first abutting portion 23 provided in one connecting portion 3 stops rotating is the same position (see FIG. 12).

即ち、本実施例は、この回動軸部４が３６０°の範囲内で左右いずれの方向に回動した際、第一突き当たり部23が同一位相位置で過回動が阻止されるように構成されており、これは、第一突き当たり部23の厚み（巾）と、第一係止部22及び第二係止部24の厚み（巾）と、第二突き当たり係止機構21に係る第二突き当たり部25と第三突き当たり部26との間隔Ｓとの設定により実現している（図13参照）。本実施例では、第一連結部３の第一突き当たり部23が被嵌部材19の第一係止部22に突き当たり係止するまでの間は、第一連結部３は被嵌部材19に対して左右いずれの方向にも３００°回動でき、被嵌部材19の第二係止部24が第二連結部５の第二突き当たり部25及び第三突き当たり部26に突き当たり係止するまでの間は、被嵌部材19は第二連結部５に対して左右いずれの方向にも６０°回動できるように構成されている。要は、第一突き当たり係止機構20によって規制される第一連結部３と被嵌部材19との相対回動範囲Ｒ１と、第二突き当たり係止機構21によって規制される第二連結部５と被嵌部材19との相対回動範囲Ｒ２との和（Ｒ１＋Ｒ２）が３６０°となるように設定すれば良い。   In other words, the present embodiment is configured such that the first abutting portion 23 is prevented from over-rotation at the same phase position when the rotation shaft portion 4 is rotated in either the left or right direction within the range of 360 °. This is because the thickness (width) of the first abutting portion 23, the thickness (width) of the first locking portion 22 and the second locking portion 24, and the second abutting and locking mechanism 21 This is realized by setting the distance S between the abutting portion 25 and the third abutting portion 26 (see FIG. 13). In the present embodiment, the first connecting portion 3 is in contact with the fitted member 19 until the first abutting portion 23 of the first connecting portion 3 abuts and is engaged with the first locking portion 22 of the fitted member 19. Until the second locking portion 24 of the fitted member 19 hits against the second butting portion 25 and the third butting portion 26 of the second connecting portion 5 and can be rotated in both directions. The fitted member 19 is configured to be able to rotate 60 ° in either of the left and right directions with respect to the second connecting portion 5. In short, the relative rotation range R1 between the first connecting portion 3 and the fitted member 19 restricted by the first abutting locking mechanism 20, and the second connecting portion 5 restricted by the second abutting locking mechanism 21. What is necessary is just to set so that the sum (R1 + R2) with relative rotation range R2 with the fitting member 19 may be 360 degrees.

以上の構成からなる過回動阻止機構17を具備したヒンジ装置Ｈを介して本体部２と重合部１とを左右方向にして水平方向に回動自在に連結する際には、重合部１が本体部２と直線状に連設状態となる位置で過回動阻止機構17が機能して回動阻止が行なわれるように組みつけられる（図12参照）。   When the main body 2 and the overlapping portion 1 are connected to each other in the horizontal direction through the hinge device H provided with the over-rotation preventing mechanism 17 having the above configuration, the overlapping portion 1 is The over-rotation prevention mechanism 17 functions in a position where it is linearly connected to the main body 2 so that the rotation is prevented (see FIG. 12).

この組み付けは、本体部２と重合部１との間に配設される配線等の捩れを考慮すると有利である。   This assembly is advantageous in consideration of twisting of wiring or the like disposed between the main body portion 2 and the overlapping portion 1.

即ち、これは、本体部２に対して重合部１を重合した状態で配線に捩れが無い状態とした場合であり、仮に、本体部２に対して重合部１が重合状態となる位置で過回動阻止機構17による過回動阻止が機能するように組み付けた場合、本体部２に対して重合部１が重合状態から３６０°相対回動可能となる為、配線は３６０°の回動による捩れを受けてしまうが、この点、重合部１が本体部２と直線状に連設状態となる位置で過回動阻止機構７による過回動阻止が機能するように組み付けた場合には、重合した状態から最大でも１８０°以上同じ方向に回動することはないから配線等の捩れが可及的に防止されることになる。   In other words, this is a case where the superposed part 1 is superposed on the main body 2 and the wiring is not twisted. If the superposed part 1 is superposed on the main body 2 at a position where it is superposed. When assembled so that the over-rotation prevention by the rotation prevention mechanism 17 functions, the overlapping portion 1 can be rotated 360 ° relative to the main body portion 2 from the overlapped state, so that the wiring is rotated by 360 °. In this point, when assembled so that the over-rotation prevention mechanism 7 functions in the position where the overlapping portion 1 is linearly connected to the main body portion 2, Since it does not rotate in the same direction by 180 ° or more at the maximum from the superposed state, the twisting of the wiring or the like is prevented as much as possible.

本実施例は上述のように構成したから、例えば本体部２を持つ手の指で重合部１を所定位置Ｐ３，Ｐ４まで水平回動させるだけで、その後は重合部１は本体部２の操作部14が露出する状態となるまで自動で水平回動することになり、非常に操作性に秀れて便利である。また、再び重合部１によって本体部２の操作部14を隠蔽する状態とする際には、手などを利用して、第一凸部７Ａ，第二凸部７Ｂが第一凹部９Ａ，第二凹部９Ｂに凹凸係合する位置まで本体部２に対して重合部１を水平回動させれば良いことになる。   Since the present embodiment is configured as described above, for example, by simply horizontally rotating the overlapping portion 1 to the predetermined positions P3 and P4 with a finger of the hand having the main portion 2, the overlapping portion 1 operates the main portion 2 thereafter. The horizontal rotation is automatically performed until the portion 14 is exposed, which is very convenient and excellent in operability. Further, when the operation portion 14 of the main body 2 is concealed again by the overlapping portion 1, the first convex portion 7A and the second convex portion 7B are used as the first concave portion 9A and the second concave portion 7B by hand. What is necessary is just to rotate the superposition | polymerization part 1 horizontally with respect to the main-body part 2 to the position which carries out uneven | corrugated engagement with the recessed part 9B.

また、本実施例は、カム部８に設ける第一凸部７Ａ，第二凸部７Ｂ、カム係合部10に設ける第一凹部９Ａ，第二凹部９Ｂ，下り面部12夫々は複数設けられている為、カム部８とカム係合部10を相対回動させた際、第一凹部９Ａ，第二凹部９Ｂから係脱した第一凸部７Ａ，第二凸部７Ｂが、同時に第一下り面部12Ａ，第二下り面部12Ｂ若しくは第三下り面部12Ｃ，第四下り面部12Ｄを２箇所当接状態（２点支持状態）で滑動することになるから、それだけ安定した状態が得られることになり、よって、回動軸部４を介して相対回動するカム部８，カム係合部10同志間で偏荷重が生じるのを確実に防止し得ることになる。この状態のまま使用を続けると、部品同士の磨耗によって形成された隙間によるガタつきが生じたり、自動回動付勢が良好に行われないという問題点が生じてしまう。   In this embodiment, a plurality of first convex portions 7A, second convex portions 7B provided on the cam portion 8, a first concave portion 9A, a second concave portion 9B, and a descending surface portion 12 provided on the cam engaging portion 10 are provided. Therefore, when the cam portion 8 and the cam engaging portion 10 are rotated relative to each other, the first convex portion 7A and the second convex portion 7B that are disengaged from the first concave portion 9A and the second concave portion 9B Since the surface portion 12A, the second descending surface portion 12B or the third descending surface portion 12C, and the fourth descending surface portion 12D are slid in a two-contact state (two-point support state), a more stable state can be obtained. Therefore, it is possible to reliably prevent the occurrence of an offset load between the cam portion 8 and the cam engaging portion 10 that rotate relative to each other via the rotation shaft portion 4. If it continues to be used in this state, there will be problems such as rattling caused by gaps formed by the wear of parts, and automatic rotation biasing not being performed satisfactorily.

また、本実施例は、本体部２に対して重合部１を左右いずれの方向にも相対回動させることができるから、例えばユーザーはその都度回動させ易い方向に回動させることができ、取り扱い性が飛躍的に向上することになり、しかも、左右いずれの方向に相対回動させた際においても、本体部２に対して重合部１を所定位置まで回動させるだけで、その後は重合部１は所定の位置まで自動で回動することになり、より一層操作性に秀れて非常に便利である。   Moreover, since the superposition | polymerization part 1 can be relatively rotated in any direction on either side with respect to the main-body part 2, the present Example can be rotated in the direction where a user is easy to rotate, for example, Handleability will be greatly improved. Moreover, even when the relative rotation is performed in either direction, it is only necessary to rotate the overlapping portion 1 to a predetermined position with respect to the main body portion 2, and then the polymerization is performed. The part 1 is automatically rotated to a predetermined position, which is very convenient because it is more excellent in operability.

尚、本発明は、本実施例に限られるものではなく、各構成要件の具体的構成は適宜設計し得るものである。   The present invention is not limited to this embodiment, and the specific configuration of each component can be designed as appropriate.
