Abstract

<P>PROBLEM TO BE SOLVED: To provide a biaxial hinge which is proof against slipout of a stopper and resistant to breakage of the same even if a rotating shaft and the stopper are downsized. <P>SOLUTION: According to the structure of the biaxial hinge, the stopper 101A and the rotating shaft 100A are integrally formed, and the integrally formed rotating shaft 100A is mounted in an opening/closing shaft 10. Then by engaging a protrusion 1011A of the integrally formed stopper 101A with an engaging portion 14 formed on the opening/closing shaft 10, the stopper inhibits the hinge from rotating in excess of a critical angle. Since the rotating shaft 100A is integrally formed, the stopper per se and a joint portion between the stopper and the rotating shaft each have a larger strength imparted thereto, and therefore a slipout accident or breakage of the stopper during rotation of the rotating shaft is prevented. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

本発明は、第１ユニットを第２ユニットに対し開閉させる開閉軸と開状態の第１ユニットをその第２ユニットに対し回動させる回動軸とを有する二軸ヒンジに関する。   The present invention relates to a biaxial hinge having an opening / closing shaft for opening and closing a first unit with respect to a second unit and a pivot shaft for rotating an opened first unit with respect to the second unit.

ビデオカメラやデジタルカメラなどでは、撮影レンズが捉えた被写体を表示パネル上に表示することによって表示パネルをファインダ代わりに使用することができるようにしているものが多い。この表示パネルが配備されているビデオカメラの中には、携帯性と使い勝手の双方を考えて、使用しないときには表示パネルがケースに重なるようにして閉状態に維持され、使用するときにはその閉状態にあった表示パネルが開状態にされ用いられるものがある。このように表示パネルを開閉させるにあたってはヒンジが用いられるが、このようなヒンジの中には表示パネルが開状態にあるときに表示パネルを回動することができるようにするため開閉軸のほかにその開閉軸と直交する回動軸を持っているものもある。このような開閉軸と回動軸とを有するものを二軸ヒンジと呼び、この二軸ヒンジに関しては構造の簡略化について様々な提案がなされている（例えば特許文献１〜特許文献３参照）。   In many video cameras and digital cameras, a display panel can be used instead of a finder by displaying a subject captured by a taking lens on the display panel. Some camcorders equipped with this display panel are kept closed so that the display panel overlaps the case when not in use, considering both portability and ease of use. Some display panels are opened and used. In order to open and close the display panel in this way, a hinge is used. In such a hinge, in addition to an opening and closing shaft, the display panel can be rotated when the display panel is in an open state. Some have a rotation axis orthogonal to the opening and closing axis. A device having such an opening / closing shaft and a rotating shaft is called a biaxial hinge, and various proposals have been made for simplification of the structure of the biaxial hinge (see, for example, Patent Documents 1 to 3).

図１は、従来の二軸ヒンジ１の構造の一例を示す図であり、図２は、図１の分解図である。   FIG. 1 is a diagram showing an example of the structure of a conventional biaxial hinge 1, and FIG. 2 is an exploded view of FIG.

図１、図２には開閉軸１０が横方向に延びた形で示されている。この開閉軸１の両端部に第１ユニット例えばケースに取り付けられる回動用部材１１，１２がそれぞれ取り付けられている。図２に示すようにその開閉軸１の中央には回動軸１００を受け入れる孔１３が設けられ、さらにその孔１３の周縁外側に係止片１４が設けられている。また、図２には回動軸１００が孔１３に挿入されて開閉軸１０に取り付けられるときに嵌挿される、別部材からなるストッパ１０１も示されている。このストッパ１０１は、回転方向に回転範囲規制用の突出部１０１１を備えており、この突出部１０１１が回動に応じて開閉軸１０の係止片１４に係止するようになっている。このようなストッパ１０１とともに回動軸１００が開閉軸１の孔１３に挿入されて図１に示す二軸ヒンジ１が組立てられる。図１には、二軸ヒンジ１の回動軸１００が回動操作により回動され、ストッパ１０１が回動軸１００とともに回って回転範囲臨界角までその回動軸１００が回動されたときに、開閉軸１０に設けられている係止部１４にストッパ１０１の突出部１０１１が係止して回転が阻止された状態が示されている。   1 and 2, the opening / closing shaft 10 is shown extending in the lateral direction. Rotating members 11 and 12 attached to a first unit, for example, a case, are attached to both ends of the opening / closing shaft 1, respectively. As shown in FIG. 2, a hole 13 for receiving the rotation shaft 100 is provided in the center of the opening / closing shaft 1, and a locking piece 14 is further provided on the outer periphery of the hole 13. FIG. 2 also shows a stopper 101 made of a separate member that is inserted when the rotation shaft 100 is inserted into the hole 13 and attached to the opening / closing shaft 10. The stopper 101 includes a protrusion 1011 for restricting the rotation range in the rotation direction, and the protrusion 1011 is engaged with the engagement piece 14 of the opening / closing shaft 10 according to the rotation. The rotating shaft 100 together with the stopper 101 is inserted into the hole 13 of the opening / closing shaft 1 to assemble the biaxial hinge 1 shown in FIG. In FIG. 1, when the rotation shaft 100 of the biaxial hinge 1 is rotated by a rotation operation and the stopper 101 rotates together with the rotation shaft 100, the rotation shaft 100 is rotated to the rotation range critical angle. The state where the protrusion 1011 of the stopper 101 is locked to the locking portion 14 provided on the opening / closing shaft 10 and rotation is prevented is shown.

このような二軸ヒンジ１の回動軸１００に例えば表示パネルが取り付けられさらに開閉軸１０端部に取り付けられている回動部材１１，１２それぞれがケースに取り付けられると、表示パネルがケースに対し開閉するとともに開状態にある表示パネルがケースに対し所定の角度範囲回動する、使い勝手の良い表示パネル部が構成される。   For example, when the display panel is attached to the rotary shaft 100 of the biaxial hinge 1 and the rotary members 11 and 12 attached to the end of the opening / closing shaft 10 are attached to the case, the display panel is attached to the case. An easy-to-use display panel unit is configured in which the open and closed display panel rotates in a predetermined angle range with respect to the case.

図３は、ストッパ１０１の外形寸法を示す図である。   FIG. 3 is a view showing the outer dimensions of the stopper 101.

図３に示すストッパ１０１は、図１，図２に示した回動軸１００が挿入される孔部１０１２を有し、その孔部１０１２は図１、図２に示した回動軸１００の端部の矩形部の寸法よりもやや大きめの矩形孔（一辺Ｄ寸法）になっている。その矩形孔の陵部にはＲ部が設けられており、そのＲ部の径がΦＣになっている。その矩形孔１０１２の縁からストッパ１４周縁に至るまでがストッパ１００の肉厚となってその肉厚によりこのストッパ１００にある程度の強度が与えられる。その外径ΦＢの寸法を持つストッパ１４の外周の一部に、開閉軸１０の係止部１４に係止する、ΦＢよりも長いΦＡの径を持つ回転規制用の突出部１０１１が設けられている。   The stopper 101 shown in FIG. 3 has a hole 1012 into which the rotating shaft 100 shown in FIGS. 1 and 2 is inserted. The hole 1012 is an end of the rotating shaft 100 shown in FIGS. The rectangular hole (one side D dimension) is slightly larger than the dimension of the rectangular part. An R portion is provided in the crest portion of the rectangular hole, and the diameter of the R portion is ΦC. The thickness from the edge of the rectangular hole 1012 to the periphery of the stopper 14 becomes the thickness of the stopper 100, and this stopper gives a certain strength to the stopper 100. On a part of the outer periphery of the stopper 14 having the outer diameter ΦB, there is provided a rotation restricting protrusion 1011 having a diameter ΦA longer than ΦB, which is engaged with the engaging portion 14 of the opening / closing shaft 10. Yes.

いままではビデオの筐体が比較的大きく回動軸１００の径を大きくしてもこのストッパ１００の各寸法をある程度大きくすることができたのでこのストッパ１０１に充分な強度を与えることができたが、筐体の小型化に伴って今後回動軸１００やストッパ１０１も小型化しなければならなくなることが予想される。しかし、回動軸１００やストッパ１０１を小型化しようとして回動軸１００の径を細くすると、ストッパ１０１の孔径やストッパ１０１の外径を細くすることはできるものの、外径が細くなったストッパ自体の強度やストッパ１０１の突出部１０１１の強度や回動軸１００とその回動軸に嵌挿されているストッパの連携部の強度が低下してしまう恐れがある。   Even if the video housing is relatively large, even if the diameter of the rotating shaft 100 is increased, the dimensions of the stopper 100 can be increased to some extent, so that the stopper 101 can be provided with sufficient strength. However, with the downsizing of the housing, it is expected that the rotating shaft 100 and the stopper 101 will have to be downsized in the future. However, if the diameter of the rotation shaft 100 is reduced in order to reduce the size of the rotation shaft 100 or the stopper 101, the hole diameter of the stopper 101 or the outer diameter of the stopper 101 can be reduced, but the stopper itself having a reduced outer diameter. And the strength of the protruding portion 1011 of the stopper 101 and the strength of the rotating shaft 100 and the cooperation portion of the stopper inserted into the rotating shaft may be reduced.

そうすると、回動軸１００が回動操作により回動されそのストッパ１０１が回動軸１００とともに回って開閉軸１０の係止部１４に係止したときに加えられる衝撃によりストッパ１０１が脱落してしまったりストッパの突出部１０１１が破損してしまったりする恐れが出てくる。また、図１に示すように別部材のストッパを組み込む構造のもの（特許文献１、特許文献２のものも同様の構造）であると、どうしてもストッパ１０１を組込むためのスペースが必要になってしまって二軸ヒンジ１が取り付けられる側の筐体の小型化に限界が生じてしまうばかりでなく、ストッパ１０１を回動軸１００に組み込む際の組立作業が煩雑になってしまって組立工数が増大してしまうという問題もある。   Then, when the rotation shaft 100 is rotated by the rotation operation and the stopper 101 rotates together with the rotation shaft 100 and is locked to the locking portion 14 of the opening / closing shaft 10, the stopper 101 falls off. There is a risk that the protrusion 1011 of the stopper may be damaged. Further, as shown in FIG. 1, if the structure is one in which a stopper of another member is incorporated (the same structure is also used in Patent Document 1 and Patent Document 2), a space for incorporating the stopper 101 is inevitably required. This not only limits the size reduction of the housing on the side where the biaxial hinge 1 is mounted, but also makes the assembly work when the stopper 101 is incorporated into the rotating shaft 100 complicated, increasing the number of assembly steps. There is also a problem that it ends up.

小型化を考えなければ、特許文献３に提案されている技術を用いることで強度をある程度は稼ぐこともできるが、特許文献３のものは元々サイズの大きな二軸ヒンジに適用される技術であって小型のものには向かない。

本発明は、上記事情に鑑み、回動軸並びにストッパ部の小型化を図ったとしても、ストッパ部が脱落せずかつ破損し難い二軸ヒンジを提供することを目的とする。   In view of the above circumstances, an object of the present invention is to provide a biaxial hinge in which the stopper portion does not fall off and is not easily damaged even if the rotating shaft and the stopper portion are reduced in size.

上記目的を達成する本発明は、第１ユニットを第２ユニットに対し開閉させる開閉軸と開状態の第１ユニットを該第２ユニットに回動させる回動軸とを有する二軸ヒンジにおいて、
上記回動軸がその回動軸の半径方向に突出した、回転範囲規制用の突出部を備えるとともに、
上記開閉軸が、上記回動軸が回転範囲臨界角まで回動されたときに上記突出部に係止してその回転角のその臨界角を超える回転を阻止する係止部を備え、
上記回転軸が、上記突出部を含め一体成型されたものであることを特徴とする。 The present invention for achieving the above object is a biaxial hinge having an opening / closing shaft for opening and closing the first unit with respect to the second unit and a rotation shaft for rotating the first unit in the open state to the second unit,
The rotation shaft includes a protrusion for restricting the rotation range, protruding in the radial direction of the rotation shaft,
The open / close shaft includes a locking portion that locks the protrusion when the rotation shaft is rotated to a rotation range critical angle and prevents rotation of the rotation angle exceeding the critical angle;
The rotating shaft is integrally formed including the projecting portion.

上記本発明の二軸ヒンジによれば、ストッパ部となる突出部を含め一体成型され回動軸とストッパが同一部品として成型加工されるため、小型化を行なったとしてもストッパ部にある程度の強度が与えられる。このため、上記回動軸が回転範囲臨界角まで回動され上記開閉軸の上記係止部に上記突出部が係止されたときにその突出部に衝撃が加えられても、いままでのようにストッパ部である突出部が脱落することはなくなる。また、一体成型されたことにより相応の強度がストッパ部に与えられているのでストッパ部が破損し難くなる。   According to the biaxial hinge of the present invention, since the rotating shaft and the stopper are molded as the same part including the protruding portion serving as the stopper portion, the stopper portion has a certain degree of strength even if it is downsized. Is given. For this reason, even if an impact is applied to the projecting portion when the pivot shaft is pivoted to the critical angle of the rotation range and the projecting portion is engaged with the engaging portion of the opening / closing shaft, the projecting portion is not affected. In addition, the protruding portion which is the stopper portion will not fall off. Moreover, since the corresponding strength is given to the stopper portion by the integral molding, the stopper portion is hardly damaged.

ここで、上記回動軸が、上記突出部を含め金属射出成型法により一体成型されたものであることが好ましい。   Here, it is preferable that the rotating shaft is integrally formed by a metal injection molding method including the protruding portion.

射出成型法は、樹脂の一体成型法の一手段として有名であり、この射出成型法を用いると任意の形状のものが容易に成型される。最近ではこの射出成型法により金属の成型を行なうことも可能になってきているので、この射出成型法を用いることで、所定の強度を持つ金属の二軸ヒンジが容易に成型される。   The injection molding method is well-known as a method for integrally molding a resin, and when this injection molding method is used, an arbitrary shape can be easily molded. Recently, it has become possible to mold metal by this injection molding method. By using this injection molding method, a metal biaxial hinge having a predetermined strength can be easily molded.

以上、説明したように、回動軸の径の縮小化およびストッパ部の小型化を図っても、ストッパ部が脱落せずかつ破損し難い二軸ヒンジが実現される。    As described above, even if the diameter of the rotating shaft is reduced and the stopper portion is reduced in size, the biaxial hinge is realized in which the stopper portion does not fall off and is not easily damaged.

以下、本発明の実施の形態について説明する。   Hereinafter, embodiments of the present invention will be described.

図４は、本発明の撮影装置の一実施形態である二軸ヒンジ１Ａの回動軸１００Ａと開閉軸１０を示す図である。また図５は、本発明の撮影装置の一実施形態である二軸ヒンジの開閉軸の分解図である。   FIG. 4 is a view showing the rotation shaft 100A and the opening / closing shaft 10 of the biaxial hinge 1A which is an embodiment of the photographing apparatus of the present invention. FIG. 5 is an exploded view of the opening and closing shaft of the biaxial hinge which is an embodiment of the photographing apparatus of the present invention.

図４に示す二軸ヒンジ１Ａは、回動軸１００Ａとストッパ１０１Ａが一体成型されている以外、図１と同様の構成のものである。   A biaxial hinge 1A shown in FIG. 4 has the same configuration as that of FIG. 1 except that a rotating shaft 100A and a stopper 101A are integrally formed.

図５を参照してこの二軸ヒンジ１Ａの構造を簡単に説明しておく。   The structure of the biaxial hinge 1A will be briefly described with reference to FIG.

まず開閉軸１の構造から説明する。この開閉軸１０は図１、図２に示したものと全く同じ構造のものである。   First, the structure of the opening / closing shaft 1 will be described. The opening / closing shaft 10 has the same structure as that shown in FIGS.

図５に示すように、開閉軸１０は支軸１０ａを備えており、その支軸１０ａが開閉軸として作用する。支軸１０ａの両端部には、その支軸１０ａを中心として回動することが自在な部材１１，１２がそれぞれ取り付けられる。それらの部材１１，１２は双方共Ｌ字状の部材であって、それらのＬ字状の部材１１，１２が備える２つの面それぞれには取付孔１１ａ，１１ｂ，１２ａ，１２ｂがそれぞれ設けられている。それら２つの面の一方の面に設けられている取付孔１１ａ，１２ａそれぞれにネジが挿入され第１のユニットである例えばケースに、この開閉軸１０が取付られると、その開閉軸の支軸１０ａつまり両端部に挟まれている中央部が回動自在になる。したがって、その支軸１０ａの中央の孔１３に回動軸１００が挿入されその回動軸１００に例えば第２ユニットである表示パネルが取り付けられると、第２ユニットである表示パネルが第１ユニットであるケースに対し開閉自在になる。さらに回動軸１００は、回動軸１００を中心として回動自在であるので表示パネルがケースに対し回動自在になる。   As shown in FIG. 5, the opening / closing shaft 10 includes a support shaft 10a, and the support shaft 10a functions as an opening / closing shaft. At both ends of the support shaft 10a, members 11 and 12 that can freely rotate about the support shaft 10a are attached, respectively. The members 11 and 12 are both L-shaped members, and mounting holes 11a, 11b, 12a, and 12b are provided on the two surfaces of the L-shaped members 11 and 12, respectively. Yes. When the opening / closing shaft 10 is attached to, for example, a case, which is the first unit, by inserting a screw into each of the mounting holes 11a, 12a provided on one of the two surfaces, the support shaft 10a of the opening / closing shaft is attached. That is, the central part sandwiched between both end parts can be rotated. Therefore, when the rotation shaft 100 is inserted into the central hole 13 of the support shaft 10a and a display panel as a second unit is attached to the rotation shaft 100, for example, the display panel as the second unit is the first unit. It can be opened and closed with respect to a certain case. Further, since the rotation shaft 100 is rotatable about the rotation shaft 100, the display panel is rotatable with respect to the case.

この例においては、組立が行ない易くなるように、図５に示す支軸１０ａの端部を中央側よりも細くしておいて上記Ｌ字状の部材の孔をそれぞれ挿入し易くしている。支軸１０ａの双方の端部にＬ字状の部材の孔を合わせるようにしてＬ字状の部材１１，１２が嵌挿されたら、それらのＬ字状の部材１１，１２が動かないようにＯリング状の止め具１１１，１２１が挿入され、さらにそのＯリング状の止め具１１１，１２１に重なるようにして外周に突起部を持つＯリング状の部材１１２，１２２が挿入されて開閉軸が組み立てられる。なお、このＯリング状の部材１１２，１２２が外周に持つ突起部は、開閉軸の開閉範囲を定めるものである。   In this example, to facilitate assembly, the end of the support shaft 10a shown in FIG. 5 is made thinner than the center side to facilitate insertion of the holes of the L-shaped members. When the L-shaped members 11 and 12 are fitted and fitted so that the holes of the L-shaped members are aligned with both ends of the support shaft 10a, the L-shaped members 11 and 12 do not move. O-ring-shaped stoppers 111, 121 are inserted, and O-ring-shaped members 112, 122 having protrusions on the outer periphery so as to overlap the O-ring-shaped stoppers 111, 121 are inserted to open and close the opening / closing shaft. Assembled. The protrusions of the O-ring-shaped members 112 and 122 on the outer periphery define the opening / closing range of the opening / closing shaft.

また、この組立てられた開閉軸１０側の支軸１０ａの中央には、回動軸１００Ａを受け入れる孔１３が設けられており、その孔１３に回動軸１００Ａの端部が回動自在になるようにして挿入されるようになっている。この回動軸１００Ａは、その回動軸１００Ａの半径方向に突出した、回転範囲規制用の突出部１０１１Ａを備えるとともに、開閉軸が、回動軸が回転範囲臨界角まで回動されたときに突出部１０１１Ａに係止して回転角の臨界角を超える回転を阻止する係止部１４を備えている。この図４には、支軸１０ａに取り付けられるようになっている、係止部１４を備えた座具１０２Ａが回動軸のすぐ下に示されている。   Further, a hole 13 for receiving the rotation shaft 100A is provided in the center of the assembled support shaft 10a on the opening / closing shaft 10 side, and the end of the rotation shaft 100A can be freely rotated in the hole 13. In this way it is inserted. The rotation shaft 100A includes a rotation range regulating protrusion 1011A protruding in the radial direction of the rotation shaft 100A, and the opening / closing shaft is rotated when the rotation shaft is rotated to the rotation range critical angle. A locking portion 14 is provided that is locked to the protruding portion 1011A and prevents rotation exceeding the critical angle of the rotation angle. In FIG. 4, a sitting tool 102 </ b> A provided with a locking portion 14 that is adapted to be attached to the support shaft 10 a is shown immediately below the rotation shaft.

ここでは開閉軸１０の支軸１０ａの中央の孔１３にストッパ１０１Ａが一体成型された回動軸１００Ａが嵌挿されさらに座具１０２Ａが取り付けられた後、止め具１０３Ａ〜１０４Ａにより回動軸が開閉軸にしっかりと取り付けられ、さらにその回動軸を覆うようにしてカバー１１０Ａが取り付けられて二軸ヒンジ１Ａが組立てられる。   Here, after the rotation shaft 100A in which the stopper 101A is integrally formed is inserted into the central hole 13 of the support shaft 10a of the opening and closing shaft 10 and the seat 102A is further attached, the rotation shaft is moved by the stoppers 103A to 104A. The biaxial hinge 1A is assembled by firmly attaching to the opening / closing shaft and further attaching the cover 110A so as to cover the rotating shaft.

いままであれば、ストッパにある程度の強度を持たせるためにどうしても回動軸の径を太くしたりストッパの内径と外形との差を大きくしたりする必要があったが、上記回動軸とストッパとが一体成型されているので、回動軸の径を細くしたとしても回動軸自体、回動軸とストッパとの連携部、さらにストッパ自体に今までのものよりも強い強度が与えられる。   If this is the case, it is necessary to increase the diameter of the rotating shaft or increase the difference between the inner diameter and the outer shape of the stopper in order to give the stopper some strength. Since the rotation shaft is made thinner, the rotation shaft itself, the link between the rotation shaft and the stopper, and the stopper itself are given stronger strength than the conventional one.

そうすると、いままでは別部材であったため、回動軸が臨界角以上回動されることを阻止しようとしたときにストッパに衝撃が加えられてストッパが脱落したり、ストッパの半径方向に突出した、回転規制用の突出部が破損したりする不具合があったが、そういった不具合がすべて解消される。   Then, since it was a separate member so far, when it was tried to prevent the rotation shaft from rotating beyond the critical angle, an impact was applied to the stopper and the stopper fell off or protruded in the radial direction of the stopper There was a problem that the rotation restricting protrusion was damaged, but all such problems were solved.

このように回動軸を一体成型するにあたっては、金属射出成型方法を用いるのが良く、この金属射出成型法を用いると、任意の形状のものを容易に成型することができる。また、上記したようにストッパを挿入する必要がなくなり組立が容易になるので組立工数が削減されるという効果も得られる。   Thus, in integrally molding the rotating shaft, it is preferable to use a metal injection molding method, and if this metal injection molding method is used, an arbitrary shape can be easily molded. In addition, as described above, there is no need to insert a stopper, and assembly is facilitated, so that an effect of reducing the number of assembly steps can be obtained.
