【０００１】
【発明の属する技術分野】
本発明は、監視用のカメラを収納する筐体、詳しくは、上カバーを真上に持ち上げるようにしてカメラの設置、ピント調整、メンテナンスを容易に行うことができるカメラハウジングに関するものである。
【０００２】
【従来の技術】
従来のカメラハウジングとしては、図１６に示すように、カメラ１を収納する筒状のケース２の前蓋３を開ける構造のものが知られている。５は吊下取付部材、６は電線である。
また、図１７及び図１８に示すように、上蓋７が開く構造のものも知られている。
図１７はカメラを収納する下ケース８を取付具１０を介して壁面１１に取り付ける場合を示し、上蓋７は下ケース８に回動可能に取り付けられている。
図１８は上蓋７を取付具１２を介して天井１３に取り付ける場合を示し、下ケース８は上蓋７に回動可能に取り付けられている。
【０００３】
【発明が解決しようとする課題】
図１６に示す前蓋が開く構造では、カメラの側面にある調整ボリュームを操作することができず、かつ、配線工事を行い難く、メンテナンスもし難いという問題がある。
また、図１７、図１８に示す上蓋が開く構造では、カメラハウジングの機種を共通化することができず、かつ、カメラ調整の際、上蓋が映り調整し難く、さらに、カメラ側面にある調整ボリュームを操作することができないという問題がある。また、とくに図１８に示す構造では、ピント合わせを行い難いという問題がある。
【０００４】
本発明は上記の諸点に鑑みなされたもので、本発明の目的は、リフト構造体を設けて上蓋（上カバー）を真上方向に持ち上げるようにすることにより、カメラの調整、メンテナンス等を容易に行うことができるようにしたカメラハウジングを提供することにある。
【０００５】
【課題を解決するための手段】
上記の目的を達成するために、本発明のカメラハウジングは、監視カメラを収納するための上部が開口した下ケースの両端に、回動構造、折畳自在構造及び伸縮自在構造のいずれか又はこれらを組み合わせたリフト構造体を介してカメラハウジングの上カバーを、該上カバーを真上に持ち上げ、かつ、下ケースを開いた状態に固定するように取り付けてなるように構成されている。
【０００６】
また、本発明のカメラハウジングは、監視カメラを収納するための上部が開口した下ケースと上カバーとを包含するカメラハウジングにおいて、下ケースの上部パネルを枢支するためのピン挿通孔を一端に備えた横断面略コ字状のリフトバーの先端に、ボルト挿通孔を設け、上カバーの下面中央部に、下ケースに回動可能に接続されたリフトバーの先端を挿入するための横断面略コ字状の水平部材を取り付け、この水平部材の両端からほぼ中央部にかけて２つの長孔を一直線上に設け、これらの長孔及びリフトバー先端のボルト挿通孔にボルトを挿入してナットで締結し、これらのボルトの頭部と水平部材の長孔との間にバネ材を介在させるとともに、ナットの内面にストッパー用突起を一体に設け、水平部材の長孔のナット側の両端部を、ストッパー用突起が嵌り込む大きさの大径孔に形成して、ナット内面のストッパー用突起が長孔の大径孔に嵌り込んでいるときは、リフトバーは固定され、ボルトの頭部をバネ材の力に抗して押圧することによりナット内面のストッパー用突起が長孔の大径孔から抜けると、リフトバーは回動するように構成されたことを特徴としている（図１〜図８参照）。
【０００７】
さらに、本発明のカメラハウジングは、監視カメラを収納するための上部が開口した下ケースと上カバーとを包含するカメラハウジングにおいて、下ケースの上部パネルを枢支するためのピン挿通孔を有する枢支片を一端に備えた下部リフトバーの他端に、接続用蝶番を介して上部リフトバーの一端を、直線状から折り畳まれる状態まで略１８０度の角度を回動自在に取り付け、上部リフトバーの他端に上カバーをねじ止めするためのねじ挿通孔を有する取付部材を備えた上カバー用蝶番を取り付け、上部リフトバーの両側に係合孔を有する側面板を一体に設け、これらの側面板に、側面板の内側から略Ｕ字状棒材の先端部を外側に延設してなる固定ロック部材の先端部を前記係合孔に挿入することにより固定ロック部材を回動自在に取り付け、該係合孔の前記接続用蝶番側の側面板の内側に、固定ロック部材を係合させるとともに略Ｕ字状棒材の他端部を下部リフトバーに当接させて接続用蝶番の回動を抑止させて下部リフトバーと上部リフトバーとを略一直線状に固定するための係合用突起を一体に設けたことを特徴としている（図１３〜図１５参照）。
【０００８】
これらのカメラハウジングにおいて、上カバーがカメラハウジングの側面カバーを兼ねているように構成することが好ましい。
また、これらのカメラハウジングは、上カバーの上面に天井取付部材を取り付けて天井に固定するようにしたり、下ケースの下面に壁面取付部材又は旋回台取付部材を取り付けて壁面又は旋回台に固定するようにしたりして用いられる。
【０００９】
【発明の実施の形態】
以下、本発明の実施の形態を説明するが、本発明は下記の実施の形態に何ら限定されるものではなく、適宜変更して実施することができるものである。
図１〜図４は、本発明の実施の第１形態によるカメラハウジングを示し、図１は上カバーを開いた状態、図２は上カバーを閉じた状態、図３は側断面、図４は一部切欠平面を示している。また、図５は図４におけるボルトまわりの拡大を示し、図６は図５におけるボルトまわりの左側面を示し、図７は水平部材における長孔の一端部の大径孔まわりを示し、図８は図１におけるリフトバーを示している。
【００１０】
図１〜図４において、１５は下ケースで、監視カメラを収納するためのものである。カメラハウジングは、この下ケース１５と上カバー１６とを包含している。上カバー１６はカメラハウジングの側面カバー（側面板）を兼ねている。１７はサンシェード（日よけ）である。１８は、図８に示すように、横断面略コ字状のリフトバーで、下ケース１５の上部パネル２０をピン２１で枢支するためのピン挿通孔２２を両側の側面板２３の一端（下端）に備えている。このリフトバー１８の両側の側面板２３の先端（上端）にはボルト挿通孔２５が設けられている。
上カバー１６の下面中央部には、図３に示すように、下ケース１５に回動可能に接続されたリフトバー１８の先端（上端）を挿入するための横断面略コ字状の水平部材２６が取り付けられており、この水平部材２６の両端からほぼ中央部にかけて２つの長孔２７が一直線上に設けられている。これらの長孔２７及びリフトバー１８先端のボルト挿通孔２５にボルト２８が挿入されてナット３０で締結される。
【００１１】
これらのボルト２８の頭部３１と水平部材２６の長孔２７との間には、図５及び図６に示すように、コイルスプリング、板バネ等のバネ材３２が介在させられるとともに、ナット３０の内面にはストッパー用突起３３が一体に設けられている。そして、水平部材２６の長孔２７のナット側の両端部は、図７に示すように、ストッパー用突起３３が嵌り込む大きさの大径孔３５に形成されている。図５の左半分に示すように、ナット３０内面のストッパー用突起３３が長孔２７の大径孔３５に嵌り込んでいるときは、リフトバー１８は図１に示す状態に固定される。すなわち、カメラハウジングは開状態となる。また、図５の右半分に示すようにボルト２８の頭部３１をバネ材３２の力に抗して矢印で示すように押圧することによりナット３０内面のストッパー用突起３３が長孔２７の大径孔３５から抜けると、ボルト２８が長孔２７内を水平方向に移動し、リフトバー１８は図１における矢印の方向に回動して、リフトバーは図２に示す状態に固定される。すなわちカメラハウジングは閉状態となる。
【００１２】
図９及び図１０は、上記のように構成されたカメラハウジングを天井１３から吊り下げて取り付ける場合を示している。図９は上カバー１６を開いた状態を示し、図１０は上カバーを閉じた状態を示している。１はカメラ、４はレンズ、１２は取付具、１７はサンシェード、３６は係止具である。
図１１及び図１２は、上記のように構成されたカメラハウジングを壁面１１に据置取り付ける場合を示している。図１１は上カバー１６を開いた状態を示し、図１２は上カバーを閉じた状態を示している。１０は取付具である。なお、壁面の代わりに旋回台に取り付ける場合もある。
【００１３】
図１３及び図１４は、本発明の実施の第２形態によるカメラハウジングを示し、図１３は上カバーを開いた状態、図１４は上カバーを閉じた状態である。また図１５はリフトバーのロックを解除した状態を示している。
図１３〜図１５において、１５は下ケースで、監視カメラを収納するためのものである。カメラハウジングは、この下ケース１５と上カバー１６とを包含している。上カバー１６はカメラハウジングの側面カバー（側面板）を兼ねている。１７はサンシェード（日よけ）である。３７は図１５に示すように、折畳式リフト構造体である。すなわち、下ケース１５の上部パネル２０をピンで枢支するためのピン挿通孔３８を有する枢支片４０を一端（下端）に備えた横断面略コ字状の下部リフトバー４１の他端に、接続用蝶番４３を介して横断面略コ字状の上部リフトバー４２の一端が、直線状から折り畳まれる状態まで略１８０度の角度を回動自在に取り付けられている。４５は側面板で、これらの側面板４５の下端が枢支片４０となっている。
上部リフトバー４２の他端には上カバー１６をねじ止めするためのねじ挿通孔４６を有する取付部材４７を備えた上カバー用蝶番４８が取り付けられている。
【００１４】
上部リフトバー４２の両側の側面板５０には係合孔５１が設けられ、これらの側面板５０に、側面板５０の内側から略Ｕ字状棒材５２の先端部が外側に延設されてなる固定ロック部材５３の先端部５５が前記係合孔５１に挿入されることにより固定ロック部材５３を回動自在に取り付けている。
これらの係合孔５１の前記接続用蝶番４３側の側面板５０の内側には、固定ロック部材５３を係合させるとともに略Ｕ字状棒材５２の他端部（下端のループ部）５６を下部リフトバー４１に当接させて接続用蝶番４３の回動を抑止させて下部リフトバー４１と上部リフトバー４２とを略一直線状に固定するための係合用突起５７が一体に設けられている。
【００１５】
固定ロック部材５３を両側から押圧し幅を狭くして係合用突起５７の下側に移動させて係合、ロックさせると、下部リフトバー４１と上部リフトバー４２とは一直線状の伸長状態となって、カメラハウジングは図１３に示す開状態となる。一方、固定ロック部材５３を両側から押圧し幅を狭くして係合用突起５７から上方向に外すと、下部リフトバー４１と上部リフトバー４２とは接続用蝶番４３で折り畳まれた状態となって、カメラハウジングは図１４に示す閉状態となる。
【００１６】
【発明の効果】
本発明は上記のように構成されているので、つぎのような効果を奏する。
（１）リフト構造体により上カバーを真上方向に持ち上げるように構成されているので、天井吊下げ取付、壁取付、旋回台取付のいずれの場合でも、カメラのピント調整のために上カバーを開けた際はカメラが被写体方向を向く状態とすることができる。また、カメラの設置、調整、メンテナンスを容易に行うことができる。
（２）吊下げ取付用、据置取付用のカメラハウジングの機種を１機種に共通化することができる。
（３）上カバーがカメラハウジングの側面カバー（側面板）の一部を兼ねているので、カメラを取り付けたまま側面からカメラ調整を行うことができる。

The upper cover of the camera housing is attached via the lift structure combined with the upper cover so that the upper cover is lifted right above and the lower case is fixed open.
[0006]
Also, the camera housing of the present invention includes a lower case with an upper opening for housing a surveillance camera and an upper cover, and a pin insertion hole for pivotally supporting the upper panel of the lower case is provided at one end. Provided with a bolt insertion hole at the tip of the lift bar with a substantially U-shaped cross section provided, and inserted into the center of the lower surface of the upper cover, the tip of the lift bar that is pivotally connected to the lower case A letter-shaped horizontal member is attached, and two long holes are provided in a straight line from both ends of the horizontal member to a substantially central portion, bolts are inserted into the bolt insertion holes at the long holes and the lift bar end, and fastened with nuts. A spring material is interposed between the head of these bolts and the long hole of the horizontal member, and a stopper projection is integrally provided on the inner surface of the nut, and both end portions on the nut side of the long hole of the horizontal member are When the stopper protrusion on the inner surface of the nut is inserted into the large hole with a large hole, the lift bar is fixed and the bolt head is a spring material. The lift bar is configured to rotate when the stopper projection on the inner surface of the nut comes out of the large-diameter hole by pressing against the force of the nut (see FIGS. 1 to 8). .
[0007]
Furthermore, a camera housing according to the present invention includes a lower case having an upper opening for housing a surveillance camera and an upper cover. The camera housing includes a pin insertion hole for pivotally supporting an upper panel of the lower case. One end of the upper lift bar is attached to the other end of the lower lift bar with a support piece at one end via a connecting hinge so as to be rotatable at an angle of about 180 degrees from the straight shape to the folded state. The other end of the upper lift bar A top cover hinge having a mounting member having a screw insertion hole for screwing the upper cover is attached to the upper cover, and side plates having engagement holes are integrally provided on both sides of the upper lift bar. The fixed lock member is pivotably mounted by inserting the distal end portion of the fixed lock member, which is formed by extending the distal end portion of the substantially U-shaped bar from the inner side of the face plate, to the engagement hole. The locking hinge is engaged with the inside of the side plate on the connecting hinge side of the engaging hole and the other end of the substantially U-shaped bar is brought into contact with the lower lift bar to rotate the connecting hinge. This is characterized in that an engagement protrusion for integrally fixing the lower lift bar and the upper lift bar in a straight line is provided (see FIGS. 13 to 15).
