Description

本発明は、第一部材に重合した第二部材を重合面に沿って回動自在に連結する回動連結装置並びに回動連結装置を用いた携帯電話・モバイル・デジタルカメラ・ノート型パソコンなどの電子機器に関するものである。   The present invention relates to a rotary connecting device that rotatably connects a second member superposed on a first member along a superposed surface, and a mobile phone, a mobile digital camera, a notebook computer using the rotary connecting device, etc. It relates to electronic equipment.

第一部材に重合した第二部材を重合面に沿って回動させる場合、回動開始位置から回動途中位置までは戻り回動付勢力が生じることで回動開始位置での位置保持作用が生じ、この回動途中位置を超えるまで回動すると、今度は逆に例えば９０度回動位置への回動付勢力が生じて、軽い力で回動できたり、この回動付勢力を大きくすることで前記回動途中位置を超えるところまで回動すれば後は一挙にこの回動付勢力によって自動的に例えば９０度回動位置まで回動する回動連結装置が提案されている。   When the second member overlapped with the first member is rotated along the overlapping surface, a return rotation biasing force is generated from the rotation start position to the midway rotation position, thereby maintaining the position holding action at the rotation start position. If it is generated and rotated until it exceeds the position in the middle of the rotation, a reverse biasing force is generated, for example, to the 90 ° rotational position, so that it can be rotated with a light force or the rotational biasing force is increased. Thus, there has been proposed a rotation coupling device that automatically rotates to, for example, a 90-degree rotation position by this rotation biasing force once it is rotated to a position exceeding the rotation intermediate position.

例えば、ディスプレイ部をワンセグＴＶ画面として利用する携帯電話などにおいて、このディスプレイ部を縦長状態から９０度回動した横長状態に自在に切り替えできる回動連結装置として提案されている。   For example, in a mobile phone that uses a display unit as a one-segment TV screen, it has been proposed as a rotation connecting device that can freely switch the display unit from a vertically long state to a horizontally long state rotated 90 degrees.

具体的には例えば、携帯電話の操作部を設けた本体部にディスプレイ部を設けた重合部を起伏回動自在にヒンジ装置で連結し、この重合部を本体部に対して前記ヒンジ装置で起伏回動自在に連結するベース部と、このベース部に９０度回動自在に連結する重合回動部とで前記重合部を構成し、この重合部の重合回動部にディスプレイ部を設け、この重合回動部とベース部とを前記回動連結装置で連結し、本体部に対して重合状態あるいは起伏回動した開放状態で、ディスプレイ部を設けた重合回動部をベース部に対して９０度回動自在に設け、ワンセグＴＶ画面として使用する場合はこれを９０度回動して、横長ディスプレイとして使用できるように構成する。   Specifically, for example, a superposition part provided with a display unit is connected to a main body part provided with an operation part of a mobile phone by a hinge device so as to be able to turn up and down, and the superposition part is raised and lowered with respect to the main body part by the hinge device. The superposition part is composed of a base part that is pivotably connected and a superposition part that is pivotally connected to the base part by 90 degrees, and a display part is provided in the superposition part of the superposition part. The polymerization rotation part and the base part are connected by the rotation connecting device, and the polymerization rotation part provided with the display part is set to the base part in an open state in which the main body part is overlapped or undulated. It is provided so that it can be freely rotated, and when it is used as a one-segment TV screen, it is rotated 90 degrees so that it can be used as a horizontally long display.

従来提案されている回動連結装置は、前述のように回動途中位置で付勢向きが自動的に切り替わり、十分な戻り付勢が生じると共にその回動途中位置を超えれば進み付勢が生じて回動操作が軽くなったり自動回動が可能となったり、９０度回動位置がこの付勢によって位置保持されるため、非常に便利である。   As described above, in the rotation coupling device proposed in the past, the biasing direction is automatically switched at the middle position of rotation, and a sufficient return bias is generated. Thus, the rotation operation becomes lighter and automatic rotation becomes possible, and the 90-degree rotation position is held by this biasing, which is very convenient.

がしかしそのため、この付勢を生じさせるためのバネを配設しなければならないし、このバネによる付勢を生じさせながらこの回動をガイドするガイド部を設けたりする必要性があることから、構成が複雑となったり、またそれ故に正逆双方には回動はできず、片側一方向のみの９０度往復回動に限られる。   However, for this reason, a spring for generating this bias must be provided, and it is necessary to provide a guide portion for guiding this rotation while generating the bias by this spring. The structure becomes complicated, and therefore it cannot be rotated in both forward and reverse directions, and is limited to 90-degree reciprocal rotation in only one direction on one side.

本発明は、回動操作できる方向が片側一方向のみでなく、左右いずれの方向、即ち正逆いずれの回動方向にも可能であって、しかも正逆いずれの回動の際しても前述の回動途中位置を超えると戻り回動付勢から進み回動付勢に自動的に切り替わり、これまで通り回動開始位置での位置保持作用や９０度回動位置での位置保持作用や途中まで回動してやればその後は回動が軽くなったり自動回動させたりすることができ、また回動当初は回動する部材が方形状であっても角部が邪魔にならず中央を支点に横長状態に回動でき、従って簡易の構成で容易に実現可能な構成でありながら従来通りの前記作用・効果が生じる回動を実現でき、しかも簡易な構成でありながら正逆いずれに回動してもこの作用・効果を生じ、非常に使い易くそれだけ使用用途が広がり実用性に秀れ、例えばディスプレイ部を縦長状態から横長状態に切り替え使用する場合においても、いずれの方向に回動しても回動開始位置が自動的に位置保持され、いずれの方向にも少し回動して回動途中位置を超えれば軽くあるいは自動的に切り替え回動可能となり、またたとえ方形状でもスムーズに中央を支点に切り替え回動可能となる電子機器を容易に実現できる画期的な回動連結装置並びに回動連結装置を用いた電子機器を提供することを目的としている。   In the present invention, the direction in which the rotation can be performed is not limited to one direction on one side, but can be in either the left or right direction, that is, the forward or reverse rotation direction. If it exceeds the midway rotation position, it automatically switches from the return rotation bias to the advance rotation bias, and as before, the position holding action at the rotation start position and the position holding action at the 90-degree rotation position or halfway After that, the rotation can be lightened or automatically rotated, and at the beginning of rotation, even if the rotating member is square, the corner does not get in the way and the center is the fulcrum It can be rotated horizontally, so it can be easily realized with a simple structure, but it can be rotated to produce the above-mentioned effects and effects as before, and it can be rotated forward or backward with a simple structure. However, it produces this action and effect and is very easy to use. For example, even when the display unit is switched from the vertically long state to the horizontally long state, the rotation start position is automatically held regardless of the direction of rotation. However, even if it is slightly rotated and exceeds the midway position, it can be switched lightly or automatically, and even in the case of a square shape, an electronic device that can be switched smoothly with the center as a fulcrum can be easily realized. It is an object of the present invention to provide a periodical rotation coupling device and an electronic apparatus using the rotation coupling device.

添付図面を参照して本発明の要旨を説明する。   The gist of the present invention will be described with reference to the accompanying drawings.

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。   DESCRIPTION OF THE PREFERRED EMBODIMENTS 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.

第一部材１に対して第二部材２を重合面に沿って回動すると、第二部材２は連結ピン３を支点に回動するが、この際連結ピン３に対してスライドガイド部４が相対スライドすることで第二部材は径方向に所定長スライド移動しつつ回動する。   When the second member 2 is rotated along the overlapping surface with respect to the first member 1, the second member 2 is rotated with the connecting pin 3 as a fulcrum. At this time, the slide guide portion 4 is moved with respect to the connecting pin 3. By relative sliding, the second member rotates while sliding in the radial direction by a predetermined length.

一方、カム当接部５は付勢部７の付勢によりカム縁６に押圧当接しながら、このカム縁６に沿って回動移動するが、このカム縁６と連結ピン３との距離が回動方向で徐々に変化する形状にカム縁６を設定しているから、第一部材１に対して第二部材２を回動すると、カム縁６の形状に対応して（回動位置に応じて）第二部材２が径方向にスライド移動及び戻りスライド移動しながら回動することとなる。   On the other hand, the cam contact portion 5 rotates and moves along the cam edge 6 while being pressed against the cam edge 6 by the urging force of the urging portion 7, but the distance between the cam edge 6 and the connecting pin 3 is as follows. Since the cam edge 6 is set in a shape that gradually changes in the rotation direction, when the second member 2 is rotated with respect to the first member 1, the cam edge 6 corresponds to the shape of the cam edge 6 (in the rotation position). Accordingly, the second member 2 rotates while sliding and returning in the radial direction.

即ち、例えば第一部材１に取り付ける第一取付部１Ａに、前記連結ピン３とカム縁６を内縁とするカム溝９とを設け、第二部材２に取り付ける第二取付部２Ａに、連結ピン３に係合するスライドガイド部４と付勢部７によって押圧当接してカム縁６に沿ってならい移動するカム溝９に係合するカム当接部５とを設けて第一部材１と第二部材２とを回動自在に連結すると、カム当接部５がならい移動するがこのカム縁６（カム溝９）を回動開始位置に対して左右いずれの方向にも形成していることでいずれの方向にも回動可能となる。そして例えば片側の一方向に回動すると連結ピン３とカム当接部５との距離が徐々に長くなるため、付勢部７の付勢に抗して連結ピン３に対してスライドガイド部４がスライド移動（第一部材１に対して第二部材２が径方向にスライド移動）しつつ回動する。   That is, for example, the first mounting portion 1A attached to the first member 1 is provided with the connecting pin 3 and the cam groove 9 having the cam edge 6 as an inner edge, and the second mounting portion 2A attached to the second member 2 has a connecting pin. The first member 1 and the first member 1 are provided with a slide guide portion 4 that engages with the cam 3 and a cam contact portion 5 that presses and abuts with the biasing portion 7 and engages with the cam groove 9 that moves along the cam edge 6. When the two members 2 are pivotably connected, the cam abutment portion 5 moves along with this cam edge 6 (cam groove 9) formed in either the left or right direction with respect to the rotation start position. It can be rotated in either direction. Then, for example, when the rotation is performed in one direction on one side, the distance between the connection pin 3 and the cam contact portion 5 gradually increases, so that the slide guide portion 4 against the connection pin 3 against the urging force of the urging portion 7. Rotates while sliding (the second member 2 slides in the radial direction with respect to the first member 1).

このため回動当初は戻り付勢力が生じることとなり、回動開始位置での位置保持作用が生じる。またこの連結ピン３とカム当接部５との距離が徐々に大きくなることで第一部材１に対して第二部材２がそれに応じて径方向にスライド移動する。   For this reason, a return urging force is generated at the beginning of rotation, and a position holding action at the rotation start position occurs. Further, as the distance between the connecting pin 3 and the cam contact portion 5 gradually increases, the second member 2 slides in the radial direction with respect to the first member 1 accordingly.

即ち、この動きを規制制御するカム縁６の形状設定により第二部材２が第一部材１に対して径方向にスライド移動しながら回動するため、例えば第一部材１と第二部材２とが互いに同形の方形状であったり、回動させる第二部材２が横幅のある縦長方形であり、回動下辺部が所定幅ありこのまま９０度回動したのでは左右の角度が何かに当たって回動できなかったりスムーズに回動できなかったり、また中央位置を支点に回動できず横長となるように９０度回動しても中心が片側に寄った横長状態とをせざるを得なかったりする場合があるが、本発明によれば、カム縁６の形状によって９０度回動の回動当初範囲では連結ピン３とカム縁６との距離が徐々に大きくなることで、第一部材１に対して第二部材２が径方向にスライド移動しつつ（持ち上がりつつ）回動し更に回動途中位置を超えるとその距離が短くなるので今度は第二部材２は逆に径方向の戻り方向に戻りスライド移動しながら９０度回動位置へと回動するように設計したため、このカム縁６のカーブ度合の設計によってこのような問題なくスムーズに中央の連結ピン３を支点に９０度回動でき、中央を回動支点に片側に寄ることなく横長状態に倒すことができることとなる。   That is, since the second member 2 rotates while sliding in the radial direction with respect to the first member 1 by setting the shape of the cam edge 6 that restricts and controls this movement, for example, the first member 1 and the second member 2 Are the same shape of each other, or the second member 2 to be rotated is a vertical rectangle with a horizontal width, and the rotation lower side portion has a predetermined width and is rotated 90 degrees as it is. It cannot move or cannot rotate smoothly, or even if it is rotated 90 degrees so that it cannot be rotated about the center position and is horizontally long, it must be in a horizontally long state with the center on one side. However, according to the present invention, the distance between the connecting pin 3 and the cam edge 6 is gradually increased in the initial rotation range of 90 degrees depending on the shape of the cam edge 6. In contrast, the second member 2 slides in the radial direction ( The second member 2 is rotated back to the 90 ° rotation position while returning and sliding in the radial direction. The design of the cam edge 6 curve degree allows the center connecting pin 3 to be smoothly rotated 90 degrees around the fulcrum without such a problem. Can be defeated.

また、このように回動途中位置を超えると連結ピン３とカム縁６との距離は逆に徐々に短くなるため、前述のようにこの回動途中位置を超えるまではいずれの回動方向への回動に際しても付勢力７による戻り付勢力が生じ、よって回動開始位置に戻ろうとする位置保持作用が生じると共に、第一部材１に対して第二部材２をスライドさせて第二部材２の左右直角が回動の支障とならないように持ち上がりつつ回動する。そして、この付勢力７の付勢に抗して連結ピン３に対してスライドガイド部４をスライド移動させつつ回動途中位置を超えると、今度はこの付勢力７の付勢力が進み付勢力となって連結ピン３に対して戻りスライドガイド部４は逆方向にスライド移動しつつ回動することとなる。   In addition, since the distance between the connecting pin 3 and the cam edge 6 is gradually shortened when the position in the middle of the rotation is exceeded in this way, in any rotation direction until the position in the middle of the rotation is exceeded as described above. Also during the rotation, a return urging force is generated by the urging force 7, so that a position holding action for returning to the rotation start position occurs, and the second member 2 is slid with respect to the first member 1. Rotate while lifting so that the right-and-left right angle of is not hindering the rotation. When the slide guide part 4 is moved with respect to the connecting pin 3 against the urging force of the urging force 7 and exceeds the midway position, the urging force of the urging force 7 advances and the urging force is increased. Thus, the return slide guide portion 4 rotates with respect to the connecting pin 3 while sliding in the opposite direction.

従って、この回動途中位置を超えると、後は軽い力で回動できたり、自動的に回動したりさせることができると共に、９０度回動位置が位置保持され、また一度持ち上がりつつ回動した第二部材２が元に戻るようにして回動することになる。   Therefore, if the intermediate position of the rotation is exceeded, it can be rotated with a light force or automatically rotated, and the 90-degree rotation position is held and rotated while being lifted once. The second member 2 is rotated so as to return to the original state.

また、この付勢力７の強さやカム縁６の連結ピン３の距離の変化の度合の設定によって、この戻り付勢力や進み付勢力の強さを調整可能で、進み付勢力を大きくすれば回動を軽くしたり、自動的に９０度位置まで回動するように設定することも可能となる。   In addition, the strength of the return bias force and the forward bias force can be adjusted by setting the strength of the bias force 7 and the degree of change in the distance of the connecting pin 3 of the cam edge 6. It is also possible to lighten the movement or to automatically rotate to the 90 degree position.

このように、回動途中位置まで戻り付勢力が生じこの回動途中位置を超えると回動付勢力（進み付勢力）が生じるように構成できると共に、簡易な構成でこのような回動動作を正逆いずれの方向に回動しても生じるように構成すること及び、前述のように持ち上がって戻りスライドしつつスムーズに中央を支点に回動することなどが容易に実現できることとなる。   In this way, a return biasing force is generated up to the middle position of rotation, and a rotation biasing force (advance biasing force) can be generated when the middle position of rotation is exceeded, and such a rotation operation can be performed with a simple configuration. It is possible to easily realize the structure that occurs regardless of the forward and reverse directions and the smooth rotation about the center while lifting and returning and sliding as described above.

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

本発明は、携帯電話のワンセグＴＶ画面を表示できるディスプレイ部が縦長ディスプレイ状態から９０度回動して横長ディスプレイ状態にその中央を支点に切り替え回動自在に設けた携帯電話に適用したものである。   The present invention is applied to a mobile phone in which a display unit capable of displaying a one-segment TV screen of a mobile phone is rotated 90 degrees from a vertically long display state and is switched to a horizontally long display state with its center as a fulcrum. .

Can be switched to the landscape display state.

このように、本実施例ではこのベース部１を第一部材１とし、ディスプレイ部を設ける重合回動部２を第二部材２としてこれを正逆双方に９０度切り替え回動自在に回動連結装置によって連結するが、本実施例のこの回動連結装置について以下説明する。   Thus, in this embodiment, the base 1 is used as the first member 1 and the superposition rotation unit 2 provided with the display unit is used as the second member 2 so that the base member 1 can be rotated 90 degrees in both forward and reverse directions. Although it connects by an apparatus, this rotation connection apparatus of a present Example is demonstrated below.

前記第一部材１（ベース部１）に取り付ける板状の第一取付部１Ａの中央に、径方向に長さを有する長窓状のスライドガイド部４を設け、前記第二部材２（ディスプレイ部を設ける重合回動部２）に取り付ける板状の第二取付部２Ａの中央には、このスライドガイド部４が相対スライド自在に係合する回動支点となる連結ピン３を設けている。   In the center of the plate-like first attachment portion 1A attached to the first member 1 (base portion 1), a long window-like slide guide portion 4 having a length in the radial direction is provided, and the second member 2 (display portion) is provided. In the center of the plate-like second attachment portion 2A attached to the superposition rotation portion 2), a connecting pin 3 serving as a rotation fulcrum with which the slide guide portion 4 is slidably engaged is provided.

また、この第一取付部１Ａの前記スライドガイド部４を設けた長さ方向位置にカム当接部５を設け、第二取付部２Ａにこのカム当接部５がならい移動するカム縁６を内縁とするガイド溝９を設け、このスライドガイド部４を設けた第一取付部１Ａと、連結ピン３を設けた第二取付部２Ａとの間にカム当接部５をカム縁６に押圧付勢する付勢部７を設けている。   Further, a cam contact portion 5 is provided at a position in the length direction of the first attachment portion 1A where the slide guide portion 4 is provided, and a cam edge 6 on which the cam contact portion 5 moves along the second attachment portion 2A is provided. A guide groove 9 is provided as an inner edge, and the cam contact portion 5 is pressed against the cam edge 6 between the first mounting portion 1A provided with the slide guide portion 4 and the second mounting portion 2A provided with the connecting pin 3. An urging unit 7 for urging is provided.

即ち、具体的には、縦長方形板状の第二取付部２Ａに回動支点となる連結ピン３を中央に突設し、この連結ピン３に相対スライド自在に係合し径方向に長さを有する長窓状の溝を前記スライドガイド部４として同幅方形状の板状の第一取付部１Ａに設けている。   Specifically, a connecting pin 3 serving as a rotation fulcrum is provided at the center of the second mounting portion 2A in the form of a vertical rectangular plate, and the connecting pin 3 is slidably engaged with the connecting pin 3 and has a length in the radial direction. A long window-like groove having the shape is provided as the slide guide portion 4 in the plate-shaped first attachment portion 1 </ b> A having the same width.

この第一取付部１Ａの前記スライドガイド部４の長さ方向位置にピン状のカム当接部５を突設し、このカム当接部５が係合し内縁を前記カム縁６とするカム溝９を中央を境にして左右対称形状に第二取付部２Ａに設けている。   A cam having a pin-like cam contact portion 5 projecting from the first mounting portion 1A in the length direction position of the slide guide portion 4 and the cam contact portion 5 is engaged so that the inner edge serves as the cam edge 6 The groove 9 is provided in the second mounting portion 2A in a symmetrical shape with the center as a boundary.

またこの連結ピン３に第一取付部１Ａの回動に伴って回動するように左右に腕状に延びるバネ取付部10を回動自在に設け、このバネ取付部10と前記第一取付部１Ａとに抗伸バネを付勢部７として連結している。即ち、左右に延びたバネ取付部10に夫々抗伸バネとしてのコイルバネ７の一端部を取り付け、この左右のコイルバネ７を板状の第一取付部１Ａに設けた開口部11に配置されるようにし、この各コイルバネ７の他端部をこの第一取付部１Ａの開口部内縁のバネ係止部12に係止して、このバネ７が縮もうとするバネ付勢によってバネ取付部10を介して連結ピン３に対して第一取付部１Ａが引っ張り付勢され、連結ピン３を設けた第二取付部２Ａに形成したカム溝９（カム縁６）に対して第一取付部１Ａに設けたカム当接部５が押圧付勢されるように構成している。   Further, the connecting pin 3 is provided with a spring mounting portion 10 extending in the shape of an arm to the left and right so as to rotate in accordance with the rotation of the first mounting portion 1A, and the spring mounting portion 10 and the first mounting portion. The anti-extension spring is connected to 1A as an urging portion 7. That is, one end of a coil spring 7 serving as an anti-extension spring is attached to each of the left and right spring mounting portions 10, and the left and right coil springs 7 are arranged in the opening 11 provided in the plate-like first mounting portion 1A. The other end of each coil spring 7 is locked to the spring locking portion 12 at the inner edge of the opening of the first mounting portion 1A, and the spring mounting portion 10 is moved by the spring bias that the spring 7 tries to contract. The first mounting portion 1A is pulled and urged to the connecting pin 3 through the first mounting portion 1A with respect to the cam groove 9 (cam edge 6) formed in the second mounting portion 2A provided with the connecting pin 3. The provided cam contact portion 5 is configured to be pressed and biased.

従って、第一部材１に対して第二部材２が重合面に沿って回動する際、カム当接部５が付勢部７によってカム縁６に押圧当接しつつこのカム縁６と前記連結ピン３との距離の変化に応じて連結ピン３に対してスライドガイド部４が相対スライド移動して、第一部材１に対して第二部材２が前記カム縁６の形状によって径方向に自動的に相対スライド移動しつつ相対回動するように構成している。   Therefore, when the second member 2 rotates along the overlapping surface with respect to the first member 1, the cam contact portion 5 is pressed against the cam edge 6 by the biasing portion 7, and the cam edge 6 is connected to the connection portion. The slide guide portion 4 is slid relative to the connecting pin 3 in accordance with the change in the distance to the pin 3, and the second member 2 is automatically moved in the radial direction relative to the first member 1 by the shape of the cam edge 6. Thus, it is configured to relatively rotate while relatively sliding.

また、本実施例では、前記カム縁６（カム溝９）の形状は、連結ピン３を設けた位置と、第一部材１に対して第二部材２が回動開始する回動開始位置とを中央とし、この回動開始位置の左右から夫々連結ピン３へと続く形状とし、回動開始位置から正逆に回動するに際してカム当接部５がならい移動するこの左右のいずれの形状も、この回動開始位置より正逆に夫々９０度回動させるに際し、前記連結ピン３との距離が回動途中位置まで徐々に大きくなりこの回動途中位置を超えると徐々に距離が小さくなる形状に設定して、正逆いずれの方向にも回動可能であると共に、前記回動途中位置まではこのカム縁６の形状と前記付勢部７の押圧付勢によって回動開始位置へ戻ろうとする戻り回動付勢力が生じ前記回動途中位置を超えると逆に９０度回動位置へ向かおうとする回動付勢力が生じるように構成している。   In the present embodiment, the shape of the cam edge 6 (cam groove 9) includes a position where the connecting pin 3 is provided and a rotation start position where the second member 2 starts to rotate with respect to the first member 1. Is the shape that continues to the connecting pin 3 from the left and right of the rotation start position, and the left and right shapes that the cam abutment portion 5 moves in the forward and reverse directions from the rotation start position are When rotating 90 degrees forward and backward from the rotation start position, the distance from the connecting pin 3 gradually increases to the midway rotation position, and when the midway rotation position is exceeded, the distance gradually decreases. It is possible to rotate in both forward and reverse directions, and to return to the rotation start position by the shape of the cam edge 6 and the pressing force of the biasing portion 7 up to the middle position of rotation. On the contrary, when a return turning biasing force is generated and the turning middle position is exceeded, 90 Turn biasing force to be leaps to the rotational position is configured to produce.

具体的には、前記カム縁６の形状は、前記連結ピン３を設けた位置と前記回動開始位置で前記カム当接部５が位置する前記基準位置６Ａとを中央としこの中央ラインを境に、基準位置６Ａから夫々山状に滑らかに湾曲して連結ピン３位置へと続く左右対称形状とし、前記回動開始位置から正逆回動に際してカム当接部５が中央の前記基準位置６Ａから左右にならい移動する際、正逆いずれの回動も回動途中位置までは前記連結ピン３との距離が前記基準位置６Ａに比べて徐々に大きくなる形状として、この回動途中位置までは前記付勢部７によって戻り回動付勢力が生じ基準位置６Ａにあるときは位置保持作用が生じるように構成し、前記回動途中位置を超えると前記連結ピン３との距離が逆に徐々に短くなる形状として、この回動途中位置を超えると前記付勢部７によって回動付勢力が生じ正逆いずれの回動も９０度回動した位置では位置保持作用が生じるように構成している。   Specifically, the shape of the cam edge 6 is centered on the position where the connecting pin 3 is provided and the reference position 6A where the cam contact portion 5 is located at the rotation start position. In addition, each of the reference positions 6A is smoothly bent in a mountain shape and has a left-right symmetrical shape that continues to the position of the connecting pin 3, and the cam contact portion 5 is in the center at the reference position 6A when rotating forward and backward from the rotation start position. When moving from left to right, the distance between the connecting pin 3 and the reference position 6A is gradually increased from the reference position 6A until both the forward and reverse rotations are reached. The biasing unit 7 is configured to generate a position holding action when a return rotation biasing force is generated and is at the reference position 6A, and when the rotation middle position is exceeded, the distance to the connecting pin 3 is gradually increased. This turning position as a shortened shape Than the in the position where the biasing force rotating by the biasing portion 7 is caused forward and reverse and any of the 90-degree rotation pivot is constituted such that the position retention action is generated.

そして本実施例では、カム縁６の形状によって９０度回動の回動当初範囲では連結ピン３とカム縁６との距離が徐々に大きくなることで、第一部材１に対して第二部材２が径方向にスライド移動しつつ（持ち上がりつつ）回動し更に回動途中位置を超えるとその距離が短くなるので今度は第二部材２は逆に径方向の戻り方向に戻りスライド移動しながら９０度回動位置へと回動するように設計したため、このカム縁６のカーブ度合の設計によって第二部材２の下辺部左右の角部が干渉して回動できなくなることはなく、持ち上がりつつ逃げるようにしてスムーズに中央の連結ピン３を支点に９０度回動でき、中央を回動支点に片側に寄ることなく横長状態に倒すことができることとなる。   In this embodiment, the distance between the connecting pin 3 and the cam edge 6 is gradually increased in the initial rotation range of 90 ° rotation due to the shape of the cam edge 6, so that the second member with respect to the first member 1 is increased. 2 is rotated while being slid (moved up) in the radial direction, and further exceeds the midway position, the distance is shortened, so that the second member 2 is now slid back and moved back in the radial direction. Since the cam edge 6 is designed to rotate to the 90 degree rotation position, the left and right corners of the lower side of the second member 2 do not interfere with each other due to the design of the curve degree of the cam edge 6, and the cam edge 6 is lifted up. The center connecting pin 3 can be smoothly rotated 90 degrees around the fulcrum so as to escape, and the center can be tilted to the horizontally long state without moving to one side.

即ち、このように回動途中位置を超えると連結ピン３とカム縁６との距離は逆に徐々に短くなるため、前述のようにこの回動途中位置を超えるまではいずれの回動方向への回動に際しても付勢力７による戻り付勢力が生じ、よって回動開始位置に戻ろうとする位置保持作用が生じると共に、第一部材１に対して第二部材２をスライドさせて第二部材２の左右直角が回動の支障とならないように持ち上がりつつ回動する。そして、この付勢力７の付勢に抗して連結ピン３に対してスライドガイド部４をスライド移動させつつ回動途中位置を超えると、今度はこの付勢力７の付勢力が進み付勢力となって連結ピン３に対して戻りスライドガイド部４は逆方向にスライド移動しつつ回動することとなる。   That is, since the distance between the connecting pin 3 and the cam edge 6 is gradually shortened when the rotation halfway position is exceeded in this way, as described above, in any rotation direction until the rotation middle position is exceeded. Also during the rotation, a return urging force is generated by the urging force 7, so that a position holding action for returning to the rotation start position occurs, and the second member 2 is slid with respect to the first member 1. Rotate while lifting so that the right-and-left right angle of is not hindering the rotation. When the slide guide part 4 is moved with respect to the connecting pin 3 against the urging force of the urging force 7 and exceeds the midway position, the urging force of the urging force 7 advances and the urging force is increased. Thus, the return slide guide portion 4 rotates with respect to the connecting pin 3 while sliding in the opposite direction.

従って、この回動途中位置を超えると、後は軽い力で回動できたり、自動的に回動したりさせることができると共に、９０度回動位置が位置保持され、また一度持ち上がりつつ回動した第二部材２が元に戻るようにして回動することになる。   Therefore, if the intermediate position of the rotation is exceeded, it can be rotated with a light force or automatically rotated, and the 90-degree rotation position is held and rotated while being lifted once. The second member 2 is rotated so as to return to the original state.
