Description

回動連結装置並びに回動連結装置を用いた電子機器Rotating connecting device and electronic device using the rotating connecting device

　本発明は、例えば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・ノート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, for example, a rotary connecting device that rotatably connects a second member superposed on a first member along a superposed surface, and an electronic device such as a mobile phone, a mobile phone, and a laptop computer using the rotary connecting device. Is.

　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など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 the conventional electronic equipment that covers the operation part of the main body part with the overlapping and rotating superposition part, it can be folded and compactized, but the display part is also concealed in the superposition state where the operation part is concealed. In many cases, use in a compact state is inevitably limited.

　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。 Further, when operating the operation unit, it is necessary to wake up a heavy overlapping portion provided with a display unit and rotate it in a reverse direction, and there is a drawback that it is difficult to perform this opening / closing operation (especially an opening operation).

　そこで、起伏回動により開閉動作するのではなく、重合面に沿って前後方向に重合部をスライド移動して開閉動作するように構成すれば、重合部の上側面にディスプレイ部を設けることができ、例えば不使用時あるいはキー操作不要時に重合した際においても、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も露出した状態に切り替える場合は、重合面に沿って前後方向に重合部をスライド移動することで行なえるため、この開放動作も非常に容易に行なえ、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，モバイルなどの電子機器となる。 Therefore, instead of opening and closing by rolling up and down, it is possible to provide a display unit on the upper side of the overlapping part if the overlapping part slides back and forth along the overlapping surface and opens and closes. For example, when superposed when not in use or when no key operation is required, in other words, even in a compact state where the superposed part provided with the display part is superposed on the main body part to conceal the operating part, the display part is arranged on the upper side. It is possible to visually check and function the display unit, and when switching from a compacted and compacted state to a state where the operation unit is also exposed, the overlapping unit is moved back and forth along the overlapping surface. Since it can be performed by sliding, this opening operation can be performed very easily, and the usage of the device is expanded. Easy to become a mobile phone, an electronic device such as a mobile.

　一方、このように第一部材（本体部）と第二部材（重合部）とをスライド移動自在に連結するスライド装置において、本出願人は、例えば特開２００７－７１２８３号や特開２００８－２７８２２６号により、第一部材に対して第二部材をスライド移動させるだけでなく、第二部材を回動して向きを回動切り替え可能となる回動機能をスライド装置に組み込んだものを提案している。 On the other hand, in such a slide device that connects the first member (main body portion) and the second member (overlapping portion) in a slidable manner, the present applicant has disclosed, for example, Japanese Patent Application Laid-Open Nos. 2007-71283 and 2008-278226. In addition to slidably moving the second member relative to the first member, it is proposed that the slide mechanism incorporates a rotation function that allows the second member to rotate and switch the direction of rotation. Yes.

　具体的には、本体部に対してディスプレイ部を設けた重合部をスライド自在にして回動自在に連結するスライド装置とすることで、ディスプレイ部を９０度回動して縦長ディスプレイ状態から横長ディスプレイ状態に容易に切り替えることができ、しかも、体裁の良い状態となるよう、例えば重合状態がＬ字状にならずＴ字状になる見やすい状態となるように回動切り替えできるものである。このＴ字状の横長ディスプレイ状態は、ＴＶ若しくは映画などの横長映像を表示したり視聴するに有効である。 Specifically, the display unit is rotated by 90 degrees by slidably connecting the overlapping portion provided with the display unit to the main body unit so that the display unit can be rotated. It can be easily switched to a state, and can be rotated and switched so that, for example, the superposition state is not L-shaped but T-shaped so that it is easy to see. This T-shaped landscape display state is effective for displaying or viewing landscape images such as TV or movies.

　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。 DETAILED 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 showing the operation of the present invention.

　第一連結体３と第二連結体４を左右いずれか一方に相対回動させると、左右いずれか一方の軸部が回動支点となり、他方の軸部による回動軸支機能が解除されて、第一連結体３と第二連結体４の相対回動が許容される。 When the first connecting body 3 and the second connecting body 4 are rotated relative to either the left or right side, either the left or right shaft portion becomes a rotation fulcrum, and the rotation shaft support function by the other shaft portion is released. The relative rotation of the first connecting body 3 and the second connecting body 4 is allowed.

　実際に本発明に係る回動連結装置を、例えばディスプレイ部を９０度回動して縦長ディスプレイ状態からＴ字状の横長ディスプレイ状態に切り替えることができる電子機器を構成する第一部材１と第二部材２との連結構造に適用した場合、第二部材２を第一部材１に対して重合合致した状態から左右いずれの方向にも相対回動させる際、第二部材２は該第二部材２の中間位置からずれた位置に配した軸部を回動支点として回動させることで、第一部材１の端部位置に該第一部材１の長さ方向と直交する状態となる。 For example, the first member 1 and the second member constituting the electronic device that can actually switch the rotation connecting device according to the present invention from the vertically long display state to the T-shaped horizontally long display state by rotating the display unit by 90 degrees, for example. When applied to a connection structure with the member 2, when the second member 2 is rotated relative to the first member 1 in either the left or right direction from the state in which the second member 2 is overlapped, the second member 2 is By turning the shaft portion arranged at a position shifted from the intermediate position as a rotation fulcrum, the end portion of the first member 1 is in a state orthogonal to the length direction of the first member 1.

　即ち、第二部材２を第一部材１に対して相対回動させた際には、左右いずれか一方の軸部を回動支点に第二連結体４は第一連結体３に対して相対回動することになり、よって、第二連結体３が連結される第二部材２は回動しながら第一部材１の端部まで移動することで第二部材２は第一部材１に対して重合合致する状態からＴ字状の横長ディスプレイ状態となる。この動作は第二部材２を第一部材１に対して左右いずれの方向に相対回動させた際にも行われる（図８～１１参照）。 That is, when the second member 2 is rotated relative to the first member 1, the second connecting body 4 is relative to the first connecting body 3 with either one of the left and right shafts as a rotation fulcrum. Therefore, the second member 2 to which the second connecting body 3 is connected moves to the end of the first member 1 while rotating, so that the second member 2 moves relative to the first member 1. Thus, the superposition matching state is changed to a T-shaped landscape display state. This operation is also performed when the second member 2 is rotated relative to the first member 1 in either the left or right direction (see FIGS. 8 to 11).

　従って、例えば第二部材２を第一部材１に対して重合合致する状態から左右いずれの方向に相対回動させた場合にも、Ｔ字状の横長ディスプレイ状態が簡易且つ迅速に得られることになる。つまり、前述した従来技術のように第二部材２を第一部材１の長さ方向にスライドさせた後に相対回動させる二つの動作は不要であり、第二部材２を第一部材１に対して相対回動させる一つの動作で確実にＴ字状の横長ディスプレイ状態が得られ、これは第二部材２を第一部材１に対して重合合致する状態から左右いずれの方向に相対回動させた場合にも確実に達成されることになる。 Therefore, for example, when the second member 2 is rotated relative to the first member 1 in the left or right direction from the state where it coincides with the first member 1, a T-shaped landscape display state can be obtained simply and quickly. Become. That is, the two operations of rotating the second member 2 relative to the first member 1 after sliding the second member 2 in the length direction of the first member 1 as in the prior art described above are unnecessary. In this way, the T-shaped landscape display state can be reliably obtained by one operation of relative rotation, and this can be achieved by rotating the second member 2 relative to the first member 1 in either the left or right direction. This is certainly achieved in the event of a failure.

　また、本発明は、常に第一連結体３及び第二連結体４夫々に設けた左右の軸受部夫々に対して軸部が軸受されるという、複数箇所で安定的に支持される連結構造であり、よって、ガタつきが可及的に生じない良好な連結状態を実現することができる。 Further, the present invention is a connection structure that is stably supported at a plurality of locations, in which the shaft portion is always supported with respect to the left and right bearing portions provided in the first connection body 3 and the second connection body 4, respectively. Therefore, it is possible to realize a good connected state in which rattling is not generated as much as possible.

　また、本発明は、前述した構成を採用することでコンパクトに製造することができる。 Further, the present invention can be manufactured in a compact manner by adopting the configuration described above.

　具体的には、仮に互いに相対回動自在に軸着した第一連結体，第二連結体のうち、一方に設けた１８０度の円弧形状のガイド部をスライドするスライド部を他方に設けた構造としても、第二部材２を第一部材１に対して重合合致する状態から左右いずれの方向にも９０度相対回動し得る構造を実現できるが、このガイド部を設ける側の連結体を巾方向に大きくする必要があり、よって、この大きな連結体を設ける部材（第二部材）が大型化するのは勿論、第二部材を第一部材に対して直交する横長ディスプレイ状態とした際にはガイド部を設けた連結体が外部に露出してしまい体裁が悪いという問題が生じてしまう。 Specifically, a structure in which a slide portion for sliding a 180-degree arc-shaped guide portion provided on one of the first connection body and the second connection body that are pivotally attached to each other so as to be rotatable relative to each other is provided on the other side. However, it is possible to realize a structure in which the second member 2 can be rotated 90 degrees relative to the first member 1 in both the left and right directions. Therefore, when the member (second member) provided with the large connecting body is enlarged, the second member is set to be in a horizontally long display state orthogonal to the first member. The connection body provided with the guide portion is exposed to the outside, which causes a problem of poor appearance.

　この点、本発明は、前述した軸受部を互いに重合する第一連結体３と第二連結体４の双方に分割して設けた構造であるから、巾方向に大きくすることなくコンパクトに製造することができる。 In this respect, the present invention has a structure in which the above-described bearing portion is divided and provided in both the first coupling body 3 and the second coupling body 4 that are superposed on each other, so that it is compactly manufactured without increasing in the width direction. be able to.

　また、請求項４記載の発明においては、第一連結体３と第二連結体４を左右いずれか一方に相対回動させると、第一回動規制機構11によりこの相対回動は規制され、他方に相対回動させると、第二回動規制機構12によりこの相対回動は規制される。 In the invention according to claim 4, when the first connecting body 3 and the second connecting body 4 are relatively rotated to the left or right, the relative rotation is restricted by the first rotation restricting mechanism 11. When the relative rotation is performed on the other side, the relative rotation is restricted by the second rotation restriction mechanism 12.

　具体的には、第二軸部10を回動支点として第一連結体３と第二連結体４とを相対回動させる際には、第一回動規制機構11を構成する第一軸受部５及び第三軸受部７に対して第一軸部９が相対スライド移動し、この第一軸部９のスライドは第一軸受部５及び第三軸受部７の範囲にて規制されて第一連結体３と第二連結体４との相対回動は規制され、一方、第一軸部９を回動支点として第一連結体３と第二連結体４とを相対回動させる際には、第二回動規制機構12を構成する第二軸受部６及び第四軸受部８に対して第二軸部10が相対スライド移動し、この第二軸部10のスライドは第二軸受部６及び第四軸受部８の範囲にて規制されて第一連結体３と第二連結体４との相対回動は規制される。 Specifically, when the first connecting body 3 and the second connecting body 4 are relatively rotated with the second shaft portion 10 as a rotation fulcrum, the first bearing portion constituting the first rotation restricting mechanism 11 is used. The first shaft portion 9 is slid relative to the fifth bearing portion 7 and the third bearing portion 7, and the slide of the first shaft portion 9 is regulated within the range of the first bearing portion 5 and the third bearing portion 7 and is first When the relative rotation between the connecting body 3 and the second connecting body 4 is restricted, on the other hand, when the first connecting body 3 and the second connecting body 4 are rotated relative to each other using the first shaft portion 9 as a pivot point. The second shaft portion 10 is slid relative to the second bearing portion 6 and the fourth bearing portion 8 constituting the second rotation restricting mechanism 12, and the slide of the second shaft portion 10 is moved to the second bearing portion 6. And the relative rotation of the 1st coupling body 3 and the 2nd coupling body 4 is controlled in the range of the 4th bearing part 8, and.

　即ち、第二部材２を第一部材１に対して相対回動させた際には、左右いずれか一方の軸部を回動支点に第二連結体４は第一連結体３に対して相対回動する（他方の軸部が第二連結体４に対して相対スライド移動する）とともに、他方の軸部が第一連結体３に対して相対スライド移動することになり、よって、第二連結体３が連結される第二部材２は回動しながら第一部材１の端部まで移動することで第二部材２は第一部材１に対して重合合致する状態からＴ字状の横長ディスプレイ状態となる。この動作は第二部材２を第一部材１に対して左右いずれの方向に相対回動させた際にも行われる（図８～１１参照）。 That is, when the second member 2 is rotated relative to the first member 1, the second connecting body 4 is relative to the first connecting body 3 with either one of the left and right shafts as a rotation fulcrum. While rotating (the other shaft portion moves relative to the second connecting body 4), the other shaft portion moves relative to the first connecting body 3, and thus the second connection. The second member 2 to which the body 3 is connected moves to the end of the first member 1 while rotating so that the second member 2 is superposed on the first member 1 in a superposition-like manner. It becomes a state. This operation is also performed when the second member 2 is rotated relative to the first member 1 in either the left or right direction (see FIGS. 8 to 11).

　この点、本発明は、前述したガイド部として機能する軸受部を互いに重合する第一連結体３と第二連結体４の双方に設けて、前述したスライド部としての軸部をガイドする部位を分割して設けた構造であるから、巾方向に大きくすることなくコンパクトに製造することができる。 In this regard, the present invention provides the above-described bearing portion functioning as the guide portion on both the first coupling body 3 and the second coupling body 4 that are superposed on each other, and a portion for guiding the above-described shaft portion as the slide portion. Since it is a structure provided in a divided manner, it can be manufactured compactly without increasing in the width direction.

　図４に図示したように第一連結体３と第二連結体４の端部同士を重合した際、第一連結体３の第一軸受部５と第二連結体４の第三軸受部７とは、平面方向から見て一つの円弧を形成する形状に設定され、且つ、第一連結体３の第二軸受部６と第二連結体４の第四軸受部８とは、平面方向から見て一つの円弧を形成する形状に設定されている。 As illustrated in FIG. 4, when the ends of the first connecting body 3 and the second connecting body 4 are overlapped, the first bearing portion 5 of the first connecting body 3 and the third bearing portion 7 of the second connecting body 4. Is set to a shape that forms one arc when viewed from the plane direction, and the second bearing portion 6 of the first coupling body 3 and the fourth bearing portion 8 of the second coupling body 4 are from the plane direction.

The second shaft portion 10 is slidably engaged between the second bearing portion 6 and the fourth bearing portion 8 which are in a superposed state.

　この第一軸部９及び第二軸部10は、図３に図示したように適宜な金属製の部材で形成した断面円形の軸状体であり、第一軸部９は筒状に設けられ、第一部材１及び第二部材２夫々に設けられる電子部品同士を電気的に接続する配線19（フレキ）を通す部位として使用される。 As shown in FIG. 3, the first shaft portion 9 and the second shaft portion 10 are shaft-like bodies having a circular cross section formed of an appropriate metal member, and the first shaft portion 9 is provided in a cylindrical shape. The first member 1 and the second member 2 are used as portions through which wiring 19 (flexible) for electrically connecting electronic components provided on each of the first member 1 and the second member 2 is passed.

　本実施例は、第二軸部10を回動支点として第一連結体３と前記第二連結体４とを左右いずれか一方に相対回動させる際には、一つの円弧を形成する第一軸受部５及び第三軸受部７夫々に対して第一軸部９が相対スライド移動するように設けて、第一連結体３と第二連結体４との相対回動が規制される第一回動規制機構11を構成しており、一方、第一軸部９を回動支点として第一連結体３と第二連結体４とを左右いずれか他方に相対回動させる際には、一つの円弧を形成する第二軸受部６及び第四軸受部８夫々に対して第二軸部10が相対スライド移動するように設けて、第一連結体３と第二連結体４との相対回動が規制される第二回動規制機構12を構成している。 In the present embodiment, when the first connecting body 3 and the second connecting body 4 are rotated relative to either the left or right with the second shaft portion 10 as a rotation fulcrum, a first arc is formed. The first shaft portion 9 is provided so as to move relative to the bearing portion 5 and the third bearing portion 7 so that the relative rotation between the first connecting body 3 and the second connecting body 4 is restricted. On the other hand, when the first connecting body 3 and the second connecting body 4 are rotated relative to either the left or the right with the first shaft portion 9 as a rotation fulcrum, The second shaft portion 10 is provided so as to slide relative to the second bearing portion 6 and the fourth bearing portion 8 that form one arc, and the relative rotation between the first connecting body 3 and the second connecting body 4 is achieved.

　本実施例では、第一回動規制機構11は、第一軸受部５，第三軸受部７夫々の軸受部としての長さを回動支点に対して４５度の円弧となる長さに設定されており、第一連結体３と前記第二連結体４との相対回動を９０度の回動角度範囲で規制するように構成され、一方、第二回動規制機構12は、第二軸受部６，第四軸受部８夫々の軸受部としての長さを回動支点に対して４５度の円弧となる長さに設定されており、第一連結体３と第二連結体４との相対回動を９０度の回動角度範囲で規制するように構成されている。 In the present embodiment, the first rotation restricting mechanism 11 sets the lengths of the first bearing portion 5 and the third bearing portion 7 as the bearing portions to a length that forms an arc of 45 degrees with respect to the rotation fulcrum. And configured to restrict the relative rotation between the first connecting body 3 and the second connecting body 4 within a rotation angle range of 90 degrees. The length of each of the bearing portion 6 and the fourth bearing portion 8 as a bearing portion is set to a length that forms an arc of 45 degrees with respect to the rotation fulcrum, and the first connection body 3 and the second connection body 4 The relative rotation is regulated within a rotation angle range of 90 degrees.

　また、本実施例は、第一軸部９と第二軸部10とは連結部材14を介して連結されている。 Further, in the present embodiment, the first shaft portion 9 and the second shaft portion 10 are connected via a connecting member 14.

　連結部材14は、図３に図示したように適宜な金属製の板材で形成したものであり、左右端部を第一軸部９と第二軸部10に連結し、第一軸部９，第二軸部10同士の間隔を一定に保持せしめるように構成されている。 The connecting member 14 is formed of an appropriate metal plate as shown in FIG. 3, and the left and right end portions are connected to the first shaft portion 9 and the second shaft portion 10, and the first shaft portion 9, The distance between the second shaft portions 10 is configured to be kept constant.

　この連結部材14は、常に第一軸部９，第二軸部10同士の間隔を一定とすることで、第一連結体３と第二連結体４を左右に相対回動させる際、第一軸部９と第二軸部10のいずれか一方を回動支点を変えて行われる回動連結装置Ｓの作動を確実に達成することができる。 The connecting member 14 always keeps the distance between the first shaft portion 9 and the second shaft portion 10 constant, so that the first connecting body 3 and the second connecting body 4 are relatively rotated to the left and right. The operation of the rotation connecting device S performed by changing the rotation fulcrum of either the shaft portion 9 or the second shaft portion 10 can be reliably achieved.

　また、本実施例では、第一連結体３と第二連結体４とを相対回動させる際、この相対回動が良好に行われるよう相対回動する第一連結体３，第二連結体４同士を誘導する誘導部16が設けられている。 Further, in this embodiment, when the first connecting body 3 and the second connecting body 4 are relatively rotated, the first connecting body 3 and the second connecting body are relatively rotated so that the relative rotation is favorably performed. A guiding portion 16 that guides the four members is provided.

　この誘導部16は、図３に図示したように第一連結体３と第二連結体４夫々の重合面に突部16ａ，16ｂを設けて構成されおり、第一連結体３と第二連結体４との相対回動の途中で互いに当接して、第一連結体３と第二連結体４との相対回動が良好に行われるよう誘導する。 As shown in FIG. 3, the guide portion 16 is configured by providing

protrusions

16 a and 16 b on the overlapping surfaces of the first connecting body 3 and the second connecting body 4. They abut against each other in the middle of relative rotation with the body 4 and guide the relative rotation between the first connecting body 3 and the second connecting body 4 to be performed satisfactorily.

　また、本実施例では、第一連結体３と第二連結体４とを、付勢体15により、第一連結体３に対して第二連結体４を所定角度相対回動させるまでは、回動方向とは逆方向に戻り動する付勢が生じ、所定角度相対回動させると逆に回動方向に進み動する付勢が生じるように連結した構成となっている。 In the present embodiment, the first connecting body 3 and the second connecting body 4 are moved relative to the first connecting body 3 by the biasing body 15 until the second connecting body 4 is relatively rotated by a predetermined angle. An urging force that returns in the direction opposite to the rotation direction is generated, and the urging force that moves forward in the rotation direction when the relative rotation is performed at a predetermined angle is generated.

　具体的には、付勢体15は、一端を第一連結体３に連結し、他端を第二連結体４に連結した構成としている。 Specifically, the urging body 15 has a structure in which one end is connected to the first connecting body 3 and the other end is connected to the second connecting body 4.

　本実施例で使用される付勢体15は、第一部材１（第一連結体３）に枢着部材17ａを介して連結する第一材15ａと、この第一材15ａに対して離反方向に移動自在となり第二部材２（第二連結体４）に枢着部材17ｂを介して連結する第二材15ｂと、第一材15ａ及び第二材15ｂ間に架設されるシャフト15ｄに被嵌され第一材15ａ及び第二材15ｂが互いに離反方向（正逆反対方向）に付勢を伴いスライド自在に連結する発条15ｃ（コイルバネ）とを有する押圧アクチュエーターである。 The biasing body 15 used in the present embodiment includes a first material 15a connected to the first member 1 (first connection body 3) via a pivot member 17a, and a direction away from the first material 15a. The second member 15b is connected to the second member 2 (second connecting body 4) via the pivot member 17b, and the shaft 15d is installed between the first member 15a and the second member 15b. The first material 15a and the second material 15b are pressing actuators having ridges 15c (coil springs) that are slidably coupled with an urging force in a direction away from each other (forward and reverse directions).

　具体的には、第一部材１（第一連結体４に回動自在に連結する第一材15ａと、第二部材２（第二連結体４）に回動自在に連結する第二材15ｂとを、第一材15ａ及び第二材15ｂが互いに離反方向にスライド自在に連結する伸縮自在な可動体とし、この第一材15ａと第二材15ｂとの間に、第一材15ａと第二材15ｂとを離反方向にスライド付勢する発条15ｃを設けて、第一材15ａと第二材15ｂとを離反方向へ付勢する付勢機構として設けている。 Specifically, the first member 1 (a first member 15a that is rotatably connected to the first connector 4) and a second member 15b that is rotatably connected to the second member 2 (second connector 4). The first material 15a and the second material 15b are slidably connected to each other in a slidable direction so that the first material 15a and the second material 15b are connected to each other. A spring 15c that slidably biases the two materials 15b in the separating direction is provided, and is provided as a biasing mechanism that biases the first material 15a and the second material 15b in the separating direction.

　従って、第一材15ａ及び第二材15ｂからなる可動体は、第一材15ａの枢着連結部と第二材15ｂの枢着連結部とを接近方向に移動させる要領で収縮させた際、発条15ｃにより抗縮付勢が生じ、この抗縮付勢は第一連結体３及び第二連結体４夫々を互いに離反方向に付勢する付勢力となる。 Therefore, when the movable body composed of the first material 15a and the second material 15b is contracted in a manner of moving the pivot connection portion of the first material 15a and the pivot connection portion of the second material 15b in the approaching direction, Anti-shrinkage bias is generated by the ridge 15c, and this anti-shrinkage bias becomes a biasing force that biases each of the first connecting body 3 and the second connecting body 4 away from each other.

　以上の構成からなる付勢体15を第一部材１と第二部材２とを連結する回動連結装置Ｓに設ける場合、第一材15ａの枢着連結部を第一部材１（第一連結体３）に回動自在に枢着連結するとともに、第二材15ｂの枢着連結部を第二部材２（第二連結体４）に回動自在に枢着連結する。 When the urging member 15 having the above-described configuration is provided in the rotation connecting device S that connects the first member 1 and the second member 2, the pivot connecting portion of the first member 15a is the first member 1 (first connection). The body 3) is pivotally connected to the second member 15b, and the second member 15b is pivotally connected to the second member 2 (second connector 4).

　この状態で、付勢体15は、第一部材１に対する第二部材２の重合合致する状態を保持する機能を発揮する他、第一部材１に対して第二部材２を所定長相対回動させるまでは、第二部材２が重合合致する位置まで自動的に戻り回動する戻り付勢が生じ、所定長相対回動させると逆にＴ字状の状態となる位置まで自動的に進み回動する進み付勢が生じることになる。 In this state, the urging body 15 exhibits a function of maintaining a state in which the second member 2 is overlapped with the first member 1 and also rotates the second member 2 relative to the first member 1 by a predetermined length. Until the second member 2 is automatically turned to a position where the second member 2 is superposed, a return bias is generated. There will be a moving forward bias.

　尚、付勢体15としては、左右に連結端を有する略ヘ字状体で構成し、この弾性部材の左右の連結端が互いに離れようとする拡角付勢が生じるようにした付勢体、具体的には、ヘ字状の板バネ若しくはヘ字状の線バネ又は中間部を巻回してコイル状部を頂部に有して左右に連結端を有する全体視略ヘ字状のコイルバネとした付勢体を採用しても良く、本実施例の特性を発揮するものであれば適宜採用し得るものである。 The urging body 15 is constituted by a substantially square-shaped body having connecting ends on the left and right sides, and an urging body that causes an expansion urging force that causes the left and right connecting ends of the elastic member to be separated from each other. More specifically, a generally flat-shaped coil spring having a generally square-shaped coil spring or coil-shaped wire spring or a coil spring that has a coil-shaped part at the top and a left and right connecting end. The urging body may be employed as long as it exhibits the characteristics of the present embodiment.

　符号18はスペーサーである。 Numeral 18 is a spacer.

　本実施例は上述のように構成したから、本実施例に係る回動連結装置Ｓを、ディスプレイ部を９０度回動して縦長ディスプレイ状態からＴ字状の横長ディスプレイ状態に切り替えることができる電子機器を構成する第一部材１と第二部材２との連結構造に適用した場合、第二部材２を第一部材１に対して重合合致した状態から左右いずれの方向にも相対回動させる際、第二部材２は該第二部材２の中間位置からずれた位置に配した軸部を回動支点として回動させることで、第一部材１の端部位置に該第一部材１の長さ方向と直交する状態となる。 Since the present embodiment is configured as described above, the rotation connecting device S according to the present embodiment can be switched from a vertically long display state to a T-shaped horizontally long display state by rotating the display unit by 90 degrees. When applied to the connecting structure of the first member 1 and the second member 2 constituting the device, when the second member 2 is rotated relative to the first member 1 in both the left and right directions from the state of being superposed on the first member 1. The second member 2 is rotated at the end position of the first member 1 by rotating the shaft portion arranged at a position shifted from the intermediate position of the second member 2 as a rotation fulcrum. The state is orthogonal to the vertical direction.

　よって、本実施例によれば、第二部材２を第一部材１に対して重合合致する状態から左右いずれの方向に相対回動させた場合にも、第一部材１の左右側方に第二部材２が均等に突出する体裁の良いＴ字状の横長ディスプレイ状態が簡易且つ迅速に得られることになる。つまり、前述した従来技術のように第二部材２を第一部材１の長さ方向にスライドさせた後に相対回動させる二つの動作は不要であり、第二部材２を第一部材１に対して相対回動させる一つの動作で確実にＴ字状の横長ディスプレイ状態が得られ、これは第二部材２を第一部材１に対して重合合致する状態から左右いずれの方向に相対回動させた場合にも確実に達成されることになる。 Therefore, according to the present embodiment, even when the second member 2 is relatively rotated in the left or right direction from the state where the second member 2 is overlapped with the first member 1, the second member 2 is moved to the left or right side of the first member 1. A T-shaped horizontally long display state in which the two members 2 protrude evenly can be obtained easily and quickly. That is, the two operations of rotating the second member 2 relative to the first member 1 after sliding the second member 2 in the length direction of the first member 1 as in the prior art described above are unnecessary. In this way, the T-shaped landscape display state can be reliably obtained by one operation of relative rotation, and this can be achieved by rotating the second member 2 relative to the first member 1 in either the left or right direction. This is certainly achieved in the event of a failure.

　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。 Note that the present invention is not limited to this embodiment, and the specific configuration of each component can be designed as appropriate.
