Description

【０００１】
【発明の属する技術分野】
本発明は、ケーブルテレビジョン（ＣＡＴＶ）機器等に用いられる通信用中継器筐体に関する。特に、本体部と蓋部とから成る通信用中継器筐体の開閉機構に関する。
【０００２】
【従来の技術】
従来、ＣＡＴＶに用いられる中継器筐体では、例えば図８に示される構造のものが知られている（実公平３−４２７０３号公報）。図８（ａ）は中継器筐体の全体構成を示した斜視図であり、図８（ｂ）は本体部３１と蓋部３２とを連結する連結子３３の部分を側面方向から示した模式図である。
この技術では、本体部３１、蓋部３２にそれぞれ連結子３３、３４が形成され、各連結子３３、３４に設けられた挿通孔３３ａ、３４ａに止めピン３５が挿通される。そして、挿通孔３３ａに形成されたネジ孔３３ｂに外部よりボルト３７が螺着され、ボルト３７の下端にて挿通孔３３ａ、３４ａ内に配置された押し具３６の位置が調整され、この押し部３６により止めピン３５が押圧される。この技術では、ボルト３７を調整することにより、止めピン３５の押圧調整を一度行ったらそのままの状態にしておき、本体部３１と蓋部３２とを固定する図略のネジを螺緩することによって、取付側周縁３９を中心にして開閉側周縁３８を開閉自在とし、そのネジを締付けることによって取付側周縁３９を中心とした開閉側周縁３８の開閉を不可としている。
【０００３】
【発明が解決しようとする課題】
しかしながら、上記従来技術では、中継器筐体の開閉機構として、止めピン３５、押し部３６、ボルト３７などを必要とするので、部品点数が増加し、重量及び価格の増加をもたらすという問題がある。
又、上記従来技術では、挿通孔３３ａ、３４ａ内に押し具３６が配置されているので、挿通孔３３ａ、３４ａ内への止めピン３５の挿通が困難であると共に、蓋部３２の開閉を可能とするための複数の止めピン３５の位置の調整が容易ではなく、作業効率がよくないという問題がある。
【０００４】
従って、本発明の目的は、上記課題に鑑み、中継器筐体の開閉機構を簡易な構造とし、重量及び価格を低減させ、組付けの作業効率を向上させることである。
【０００５】
【課題を解決するための手段】
上記の課題を解決するために、請求項１に記載の手段によれば、一方の面が開口した開口面を有する箱状の本体部と、開口面を覆う蓋部とから成る通信用中継器筐体において、本体部又は蓋部の下端に第１ヒンジ部材として軸部が設けられる。この第１ヒンジ部材の軸部を回動自在に支持する略Ｕ字状断面の受け部を有した第２ヒンジ部材が、本体部又は蓋部のうち第１ヒンジ部材が設けられていない部材の下端に設けられる。受け部には、長手方向が回動方向に沿うように長孔が形成されている。そして、係止手段が第２ヒンジ部材の長孔を介して第１ヒンジ部材の軸部に装着され、長孔の周縁と係止することにより、第１ヒンジ部材の第２ヒンジ部材に対する相対的回動範囲が規制される。
これにより、中継器筐体の開閉機構を簡易な構造にでき、部品点数が低減し、重量及び価格を低減できる。又、係止手段を軸部に装着するだけで本体部と蓋部との組付けを容易に行うことができるので、作業効率が向上する。
【０００６】
又、請求項２に記載の手段によれば、本体部と蓋部とが回動範囲内にあるとき、両者を離間する方向の力に対して軸部が受け部の内壁面と当接するように受け部の開口部が形成される。そして、第１ヒンジ部材の軸部にはネジ孔が設けられ、このネジ孔に長孔を介して係止手段としてのネジ部材が螺着される。このネジ部材のネジ孔への螺着により、開口部からの軸部の脱落を良好に防止することができる。又、係止手段の脱着が可能となり、本体部と蓋部との組付けをより容易に行うことができる。
【０００７】
請求項３に記載の手段によれば、第１ヒンジ部材の軸部にはネジ孔が設けられ、長孔の回動方向と略直交する方向の幅より大きい外径の頭部を有したネジ部材が、ネジ孔に螺着される。これにより、本体部と蓋部とが回動範囲内にあって両者を離間する方向の力に対して軸部が受け部の内壁面と当接しない構成であっても、ネジ部材の頭部が第２ヒンジ部材の外面に当接するので、蓋部の脱落を良好に防止できる。
【０００８】
請求項４に記載の手段によれば、本体部と蓋部とが所定角度で開状態のときに係止手段が当接する位置に長孔の長手方向の一端が設けられることにより、筐体を開状態にしたとき常に所定角度で保持できる。
【０００９】
【発明の実施の形態】
以下、本発明を具体的な実施例に基づいて説明する。
図１は、ヒンジ受け（第２ヒンジ部材）１０に対してヒンジ軸（第１ヒンジ部材）２０が装着されることにより、筐体の本体部１と蓋部２との係止状態を示した斜視図である。本体部１は、一方に開口面１９を有した箱型を成している。開口面１９の四隅には凸部１８が設けられ、各凸部１８には、後述するボルト４を挿通するための挿通孔１７が形成されている。本体部１の下端１６には、ヒンジ受け１０が一対設けられている。
本体部１の開口面１９を覆う蓋部２は、本体部１の凸部１８に対応した位置に凸部２８が設けられ、各凸部２８にはボルト４を挿通するための挿通孔２７が形成されている。蓋部２の下端２６にはヒンジ受け１０に装着されるヒンジ軸２０が設けられている。
【００１０】
ヒンジ軸２０及びヒンジ受け１０の拡大斜視図を図２に示す。ヒンジ軸２０は、蓋部２の下端２６の面に略垂設された腕部２１と、腕部２１に略垂設された軸部２２と、軸部２２に貫通して設けられたネジ孔２４とから構成されている。腕部２１は、ヒンジ受け１０との装着時に腕部２１と凸部２８との間にヒンジ受け１０が配置可能なだけ凸部２８から離れた位置に設けられている。ヒンジ軸２０は、ヒンジ受け１０に対応して１対設けられているが、腕部２１から軸部２２先端への向きは互いに正反対の方向に設けられている。ネジ孔２４には、ネジ（係止手段）２５が螺着される。ネジ２５はネジ孔２４に螺着されるネジ部２５ａと、頭部２５ｂとから構成されており、頭部２５ｂは後述する長孔１４の回動方向に対して略直交する方向の幅より大きい外径を有している。
【００１１】
ヒンジ受け１０は凸部１８に連続して設けられ、略Ｕ字状の受け部１１が形成されている。受け部１１の開口部は、本体部１の開口面１９と反対側に形成され、軸部２２を配置するだけの十分な幅及び高さを有している。この受け部１１には、開口面１９と同一面に形成された延出部１２から、延出部１２に対して略垂設された垂直部１３にかけて、長孔１４が形成されている。このように、長孔１４は、その長手方向が回動方向に沿って形成されている。長孔１４は、延出部１２側に端部１４ａを、垂直部１３側に端部１４ｂを有している。端部１４ａは、本体部１と蓋部２との閉状態のときにネジ２５が当接しない位置に設けられている。端部１４ｂは、請求項でいう長手方向の一端に相当する。この長孔１４の周囲には、ネジ２５の頭部２５ｂに対する座部１５が形成されており、その曲面部は後述する軸部２２が受け部１１内に配置されたとき、軸部２２の外周面と略同心円状になるように形成されている。
【００１２】
次に、本体部１と蓋部２の組付け方法について、図２〜図６を用いて以下に説明する。
まず、図２に示されるように、ヒンジ軸２０とヒンジ受け１０とを対向配置し、蓋部２を開口面１９に対して略９０度の位置関係にしてヒンジ軸２０を矢印Ａの方向に移動させ、受け部１１内に配置する。この状態を示した斜視図が図３である。このとき、軸部２２に設けられたネジ孔２４の一端は、本体部１の下端１６側に位置している。
次に、軸部２２を回動中心として、矢印Ｂの方向に蓋部２を略９０度回動させ、開口面１９を蓋部２で覆い、本体部１と蓋部２とを閉状態にする。この状態のヒンジ受け１０及びヒンジ軸２０の近傍を示した斜視図が図４である。
【００１３】
図４に示されるように、蓋部２を回動させることで、本体部１の凸部１８と蓋部２の凸部１８とが重なり、挿通孔１７と挿通孔２７とが位置合わせされる。このとき、軸部２２は略９０度回動することにより、ネジ孔２４は受け部１１の延出部１２側の長孔１４の位置に位置する。
そして、長孔１４を介してネジ孔２４にネジ２５を螺着する。この状態を示した斜視図が図５である。このとき、ネジ２５の頭部２５ｂの下面は、必ずしも座部１５に当接していなくともよい。
この状態で、ネジ２５が長孔１４の端部１４ａに当接し、開状態ではネジ２５が端部１４ｂと当接する。図６は、開状態においてネジ２５と端部１４ｂとの当接状態を示した断面図である。この図に見られるように、ネジ２５が端部１４ｂに当接することにより、本体部１と蓋部２との開状態において所定角度に保持することができる。尚、本実施例では、蓋部２が本体部１に対して略９０度の角度に保持されるようにした。これにより本体部１と蓋部２とは長孔１４の端部１４ａ、１４ｂとネジ２５とが当接する範囲内で回動する。この回動範囲内にあるとき、両者を離間する方向の力に対して軸部２２と受け部１１の内壁面とが当接するので、その方向の力により軸部２２が受け部１１から脱落することはない。
又、ネジ２５を螺着した後、ワッシャ３を介してボルト４を挿通孔１７、２７に挿通し、ボルト４とナット（図略）とを螺着させることにより本体部１と蓋部２とを固定する。図７は、この状態を示した模式図である。
【００１４】
上記構成とすることにより、各ボルト４を螺緩した状態において、受け部１１内に配置された軸部２２のネジ孔２４に、長孔１４を介してネジ２５が螺着されているので、蓋部２の脱落を防止することができる。又、長孔１４が回動方向に沿って設けられているので、蓋部２を本体部１に係止した状態で軸部２２を中心に回動させることが可能であり、ネジ２５が長孔１４の端部１４ｂに当接した位置で蓋部２を保持することができる。
又、本体部１と蓋部２の開閉機構を、ヒンジ軸２０、ヒンジ受け１０及びネジ２５のみで構成できるので、簡易な構造にでき、部品点数を低減し、コスト及び重量を低減できる。
又、ヒンジ軸２０をヒンジ受け１０に装着し、ネジ２５をネジ孔２４に螺着するだけで本体部１と蓋部２とを回動自在に組付けることができるので、組付けの作業効率が格段に向上する。
【００１５】
上記実施例では、ネジ孔２４は軸部２２を貫通した構成としたが、このネジ孔２４は軸部２２を貫通していなくともよい。
又、上記実施例では、本体部１にヒンジ受け１０を設け、それに対応して蓋部２にヒンジ軸２０を設けた構成としたが、本体部１にヒンジ軸を設け、蓋部２にヒンジ受けを設けてもよい。又、上記実施例では、本体部１、蓋部２は、それぞれ対を成すヒンジ部材のうち一方の種類のみを設けたが、それぞれに双方の種類のヒンジ部材を設けてもよい。
又、上記実施例では、係止手段としてネジ２５を用い、ネジ孔２４にネジ２５を螺着する構成としたが、蓋部２の脱落を防止でき、ヒンジ軸２０をヒンジ受け１０に対して回動自在に支持できるものであれば他の部材を用いてもよい。例えば、軸部２２に孔部を設け、この孔部に係止手段を嵌め合いにより装着する構成としてもよい。特に、本実施例の如く、本体部１と蓋部２とが回動範囲内にあるとき両者を離間する方向の力に対して軸部２２と受け部１１の内壁面とが当接する場合には、ヒンジ軸２０とヒンジ受け１０とが係止状態にあるので、係止手段に頭部を備えなくともよい。この場合には、ヒンジ受け１０の外面からの係止手段の突出量が、軸部２２の受け部１１内での移動可能量より大きければヒンジ受け１０とヒンジ軸２０との係止を十分に行える。
【００１６】
又、上記実施例では、本体部１と蓋部２とが回動範囲内にあるとき両者を離間する方向の力に対して軸部２２と受け部１１の内壁面とが当接するように、受け部１１の開口部を開口面１９と反対方向に形成したが、この開口部は任意の方向に形成してよい。例えば、受け部１１の開口部を本体部１の下端１６方向に形成することで、本体部１と蓋部２との回動範囲を広くとることが可能である。又、受け部１１の開口部を、本体部１の開口面１９と同一方向に形成し、軸部２２を本体部１と蓋部とが回動範囲内にあるとき両者を離間する方向の力に対して軸部２２と受け部１１の内壁面とが当接しない構成としてもよい。ただし、この場合には係止手段に頭部を備え、この頭部をヒンジ受け１０に係止させることによりヒンジ軸２０の抜けを防止する必要がある。
又、上記実施例では、開状態において蓋部２が本体部１に対して略９０度に保持される構成としたが、この角度は任意であってよい。尚、開状態における蓋部２と本体部１との成す角度は、長孔１４の端部１４ｂを変化させることで調整可能である。
又、上記実施例では、閉状態においてネジ２５が端部１４ａに当接する構成としたが、閉状態においてネジ２５が端部１４ａに当接していなくともよい。
又、上記実施例では、ヒンジ受け１０が凸部１８に連続して設けられた構成としたが、ヒンジ受け１０は任意の位置に設けられてよい。
又、上記実施例では、ヒンジ軸２０における腕部２１から軸部２２先端への向きが正反対になるように設けられているが、この向きは同一方向又は対向した方向でもよい。

According to a third aspect of the present invention, a screw hole is provided in the shaft portion of the first hinge member and has a head having an outer diameter larger than the width in the direction substantially orthogonal to the rotation direction of the long hole. The member is screwed into the screw hole. Thus, even if the main body portion and the lid portion are within the rotation range and the shaft portion does not come into contact with the inner wall surface of the receiving portion with respect to the force in the direction to separate them, the head portion of the screw member Comes into contact with the outer surface of the second hinge member, so that the lid portion can be prevented from falling off.
[0008]
According to the fourth aspect of the present invention, the one end in the longitudinal direction of the elongated hole is provided at a position where the locking means abuts when the main body portion and the lid portion are in the open state at a predetermined angle. When opened, it can always be held at a predetermined angle.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described based on specific examples.
FIG. 1 shows a state in which the main body portion 1 and the lid portion 2 of the housing are locked by attaching a hinge shaft (first hinge member) 20 to the hinge receiver (second hinge member) 10. It is a perspective view. The main body 1 has a box shape having an opening surface 19 on one side. Convex portions 18 are provided at the four corners of the opening surface 19, and through holes 17 for inserting bolts 4 to be described later are formed in the respective convex portions 18. A pair of hinge receivers 10 are provided at the lower end 16 of the main body 1.
The lid portion 2 that covers the opening surface 19 of the main body 1 is provided with a convex portion 28 at a position corresponding to the convex portion 18 of the main body 1, and each convex portion 28 has an insertion hole 27 for inserting the bolt 4. Is formed. A hinge shaft 20 attached to the hinge receiver 10 is provided at the lower end 26 of the lid portion 2.
[0010]
An enlarged perspective view of the hinge shaft 20 and the hinge receiver 10 is shown in FIG. The hinge shaft 20 includes an arm portion 21 substantially suspended from the surface of the lower end 26 of the lid portion 2, a shaft portion 22 substantially suspended from the arm portion 21, and a screw hole provided through the shaft portion 22. 24. The arm portion 21 is provided at a position separated from the convex portion 28 so that the hinge receiver 10 can be disposed between the arm portion 21 and the convex portion 28 when the arm portion 21 is attached to the hinge receiver 10. A pair of hinge shafts 20 are provided corresponding to the hinge receiver 10, but the directions from the arm portion 21 to the tip of the shaft portion 22 are provided in opposite directions. A screw (locking means) 25 is screwed into the screw hole 24. The screw 25 includes a screw portion 25a that is screwed into the screw hole 24, and a head portion 25b. The head portion 25b is larger than a width in a direction substantially orthogonal to the rotation direction of the long hole 14 described later. It has an outer diameter.
[0011]
The hinge receiver 10 is provided continuously with the convex portion 18 to form a substantially U-shaped receiving portion 11. The opening portion of the receiving portion 11 is formed on the opposite side of the opening surface 19 of the main body portion 1 and has a sufficient width and height to dispose the shaft portion 22. In the receiving portion 11, a long hole 14 is formed from an extending portion 12 formed on the same plane as the opening surface 19 to a vertical portion 13 substantially suspended from the extending portion 12. Thus, the long hole 14 is formed such that its longitudinal direction is in the direction of rotation. The long hole 14 has an end portion 14a on the extending portion 12 side and an end portion 14b on the vertical portion 13 side. The end portion 14 a is provided at a position where the screw 25 does not contact when the main body portion 1 and the lid portion 2 are closed. The end portion 14b corresponds to one end in the longitudinal direction in the claims. A seat portion 15 for the head portion 25b of the screw 25 is formed around the elongated hole 14, and the curved surface portion is an outer periphery of the shaft portion 22 when a shaft portion 22 described later is disposed in the receiving portion 11. It is formed so as to be substantially concentric with the surface.
[0012]
Next, a method for assembling the main body 1 and the lid 2 will be described below with reference to FIGS.
First, as shown in FIG. 2, the hinge shaft 20 and the hinge receiver 10 are arranged to face each other, the lid portion 2 is positioned approximately 90 degrees with respect to the opening surface 19, and the hinge shaft 20 is moved in the direction of the arrow A. Move and place in the receiving part 11. FIG. 3 is a perspective view showing this state. At this time, one end of the screw hole 24 provided in the shaft portion 22 is located on the lower end 16 side of the main body portion 1.
Next, with the shaft portion 22 as the center of rotation, the lid portion 2 is rotated approximately 90 degrees in the direction of arrow B, the opening surface 19 is covered with the lid portion 2, and the main body portion 1 and the lid portion 2 are closed. To do. FIG. 4 is a perspective view showing the vicinity of the hinge receiver 10 and the hinge shaft 20 in this state.
[0013]
As shown in FIG. 4, by rotating the lid portion 2, the convex portion 18 of the main body portion 1 and the convex portion 18 of the lid portion 2 overlap, and the insertion hole 17 and the insertion hole 27 are aligned. . At this time, the shaft portion 22 rotates approximately 90 degrees, so that the screw hole 24 is positioned at the position of the long hole 14 on the extending portion 12 side of the receiving portion 11.
Then, a screw 25 is screwed into the screw hole 24 through the long hole 14. FIG. 5 is a perspective view showing this state. At this time, the lower surface of the head 25 b of the screw 25 does not necessarily have to contact the seat portion 15.
In this state, the screw 25 contacts the end portion 14a of the long hole 14, and in the open state, the screw 25 contacts the end portion 14b. FIG. 6 is a cross-sectional view showing a contact state between the screw 25 and the end portion 14b in the open state. As can be seen in this drawing, the screw 25 abuts against the end portion 14b, whereby the main body portion 1 and the lid portion 2 can be held at a predetermined angle. In this embodiment, the lid portion 2 is held at an angle of about 90 degrees with respect to the main body portion 1. As a result, the main body 1 and the lid 2 are rotated within a range where the ends 14 a and 14 b of the long hole 14 and the screw 25 are in contact with each other. When in this rotation range, the shaft portion 22 and the inner wall surface of the receiving portion 11 abut against the force in the direction of separating them, so that the shaft portion 22 falls off the receiving portion 11 by the force in that direction. There is nothing.
Further, after the screw 25 is screwed, the bolt 4 is inserted into the insertion holes 17 and 27 through the washer 3, and the bolt 4 and the nut (not shown) are screwed together, whereby the main body 1 and the lid 2 are connected. To fix. FIG. 7 is a schematic diagram showing this state.
[0014]
By adopting the above configuration, in the state where each bolt 4 is loosened, the screw 25 is screwed into the screw hole 24 of the shaft portion 22 disposed in the receiving portion 11 via the long hole 14. It is possible to prevent the lid 2 from falling off. Further, since the long hole 14 is provided along the rotation direction, it is possible to rotate the shaft portion 22 around the lid portion 2 in a state where the lid portion 2 is locked to the main body portion 1, and the screw 25 is long. The lid 2 can be held at a position in contact with the end 14 b of the hole 14.
Further, since the opening / closing mechanism of the main body 1 and the lid 2 can be constituted by only the hinge shaft 20, the hinge receiver 10 and the screw 25, the structure can be simplified, the number of parts can be reduced, and the cost and weight can be reduced.
Further, since the main body 1 and the lid 2 can be rotatably assembled simply by mounting the hinge shaft 20 to the hinge receiver 10 and screwing the screw 25 into the screw hole 24, the work efficiency of the assembly Is significantly improved.
[0015]
In the above embodiment, the screw hole 24 penetrates the shaft portion 22, but the screw hole 24 does not have to penetrate the shaft portion 22.
In the above embodiment, the main body 1 is provided with the hinge receiver 10 and the lid 2 is provided with the hinge shaft 20 correspondingly. However, the main body 1 is provided with the hinge shaft, and the lid 2 is hinged. A receptacle may be provided. Moreover, in the said Example, although the main-body part 1 and the cover part 2 provided only one kind among the hinge members which make a pair, respectively, you may provide both types of hinge members in each.
In the above embodiment, the screw 25 is used as the locking means, and the screw 25 is screwed into the screw hole 24. However, the lid 2 can be prevented from falling off, and the hinge shaft 20 is attached to the hinge receiver 10. Other members may be used as long as they can be rotatably supported. For example, it is good also as a structure which provides a hole part in the axial part 22, and attaches a latching means to this hole part by fitting. In particular, as in this embodiment, when the main body 1 and the lid 2 are within the rotation range, the shaft 22 and the inner wall surface of the receiving portion 11 come into contact with the force in the direction of separating the two. Since the hinge shaft 20 and the hinge receiver 10 are in the locked state, the locking means need not have a head. In this case, if the protruding amount of the locking means from the outer surface of the hinge receiver 10 is larger than the movable amount of the shaft portion 22 in the receiving portion 11, the hinge receiver 10 and the hinge shaft 20 are sufficiently locked. Yes.

Moreover, in the said Example, when the main-body part 1 and the cover part 2 are in the rotation range, with respect to the force of the direction which separates both, the axial part 22 and the inner wall face of the receiving part 11 contact | abut. Although the opening part of the receiving part 11 was formed in the direction opposite to the opening surface 19, this opening part may be formed in arbitrary directions. For example, by forming the opening of the receiving portion 11 in the direction of the lower end 16 of the main body 1, it is possible to widen the rotation range of the main body 1 and the lid 2. Further, when the opening portion of the receiving portion 11 is formed in the same direction as the opening surface 19 of the main body portion 1 and the shaft portion 22 is in the range of rotation when the main body portion 1 and the lid portion are within the rotation range, the force in the direction to separate them from each other However, the shaft portion 22 and the inner wall surface of the receiving portion 11 may not be in contact with each other. However, in this case, it is necessary to prevent the hinge shaft 20 from coming off by providing the locking means with a head and locking the head to the hinge receiver 10.
Moreover, in the said Example, although it was set as the structure by which the cover part 2 is hold | maintained at about 90 degree | times with respect to the main-body part 1 in the open state, this angle may be arbitrary. The angle formed between the lid 2 and the main body 1 in the open state can be adjusted by changing the end 14b of the long hole 14.
In the above embodiment, the screw 25 is in contact with the end portion 14a in the closed state, but the screw 25 may not be in contact with the end portion 14a in the closed state.
Moreover, in the said Example, although it was set as the structure by which the hinge receiver 10 was continuously provided in the convex part 18, the hinge receiver 10 may be provided in arbitrary positions.
Moreover, in the said Example, although it provided so that the direction from the arm part 21 in the hinge axis | shaft 20 to the front-end | tip part of the axial part 22 might become opposite, this direction may be the same direction or the direction which opposes.
