Description

【０００１】
【発明の属する技術分野】
本発明は、ファン取付装置に係わり、とくに、ファンを屋根付き収容箱の天板に取り付けるためのものに関する。
【０００２】
【従来の技術】
従来、図１に示すように、天板１上方に屋根２を、前面開口３ａに扉４を備え、内部にカメラ制御盤等の電子機器５を収容して戸外に設置される屋根付き収容箱３の内部の熱を同収容箱３の天板１と屋根２との間に設けられた隙間から排気するためのファン６を同天板１に設けたファン取付孔１ａに取り付けるファン取付装置１０は、例えば、図４および図５に示すように、凸字状に折曲して形成され、下面１１ａにネジ孔１１ａ１を有し、上方に突出する上面１１ｂの中央に、排気口１２ａを有するフード１２を形成し、同フード１２を前記ファン取付孔１ａに嵌着してなる取付枠１１と、同取付枠１１の下方に配置され、中央に前記フード１２に対応する通風孔１３ａを有し、同通風孔１３ａ周縁に前記ファン６を固定するネジ孔１３ｂと、同ネジ孔１３ｂの外周縁に前記ネジ孔１１ａ１に対応する挿通孔１３ｃを形成した取付金具１３とで構成し、ファン６を前記取付金具１３の下面にネジ２０で固定し、同取付金具１３の挿通孔１３ｃから前記取付枠１１のネジ孔１１ａ１にネジ２１を螺着して固定するようにしていた。
しかしこの構成では、前記ファン６をネジ２０で固定した取付金具１３を前記取付枠１１にネジ止めするにはネジ２１を下方からスクリュードライバを当ててネジ止めしなければならず、前記収容箱３の高さをスクリュードライバが使用できるように高くしなければならず、収容箱の大きさを小さくすることができないという問題があった。
【０００３】
【発明が解決しようとする課題】
本発明は以上述べた問題点を解決し、収容箱の高さを低くしてもファンを取り付けることができ、また、収容箱の実質的な容積を増やすことのできるファン取付装置を提供することを目的としている。
【０００４】
【課題を解決するための手段】
本発明は上述の課題を解決するため、天板上方に屋根を、前面開口に扉を備え、内部にカメラ制御盤等の電子機器を収容して戸外に設置される屋根付き収容箱の内部の熱を同収容箱の天板と屋根との間に設けられた隙間から排気するためのファンを同天板に設けたファン取付孔に取り付けるものであって、前記ファン取付孔に開口部を有する突出部を嵌着し、下部に取付部を有する略凸字状の取付枠と、同取付枠の下方に配置され、中央に前記開口に対応する通風孔を備え、同通風孔に対応して前記ファンを固定するファン取付板と、同ファン取付板と一体に形成され、前記取付部にネジで固定される固定部とでなる取付金具とで構成したファン取付装置において、
前記取付部および固定部の取付面を前面に配置し、前記収容箱前面よりネジ止めするようにしたファン取付装置としている。
【０００５】
前記取付部が前記突出部の下部前端を下方に折曲して形成され、前記固定部を取付ける挿通孔を備える一方、前記固定部が前記ファン取付板の前端を垂直に折曲して形成され、前記挿通孔に対応するネジ孔を設けてなるファン取付装置としている。
【０００６】
前記ファン取付板が、下方に突出して凹状に形成され、同凹状部の上面にファンを固定するようにしてなるファン取付装置としている。
【０００７】
前記取付枠の突出部が、前記ファンを収容する寸法に形成されてなるファン取付装置としている。
【０００８】
前記取付枠の下部後端を下方に延出し、同延出部に係止孔を設ける一方、前記取付金具の後方に同係止孔に係合する突起を設けたファン取付装置としている。
【０００９】
前記取付枠の突出部周縁に、前記ファン取付孔周縁に係止する複数の係止用突起を設け、取付枠がファン取付孔にしっかり固定されるようにしたファン取付装置としている。
【００１０】
前記取付枠の突出部の開口には金網等の防虫網を貼付し、外部から虫が進入しないようにしたファン取付装置としている。
【００１１】
【発明の実施の形態】
以上のように、本発明のファン取付装置においては、ファン取付孔に嵌着する突出部の上方を開口し、下部前端に挿通孔を備える取付部を下方に延出した略凸字状の取付枠と、同取付枠の下方に配置され、前方に同挿通孔に対応するネジ孔を形成した固定部を、中央に前記突出部開口に対応する通風孔を設け、同通風孔周縁に前記ファンを固定するネジ孔を有するファン取付板を備えた取付金具とでなるので、ファンを固定した前記取付金具を取付枠の下方に配置した後、収容箱前方から後方に向けてスクリュードライバを操作することにより、取付枠の挿通孔から取付金具の固定部に備えるネジ孔にネジを螺合して取付金具を取付枠に固定するので、前記収容箱の前面から取付作業ができ、取付金具の下方にスクリュードライバの入る余地を設けなくともよい。
【００１２】
【実施例】
以下、図面に基づいて本発明によるファン取付装置を詳細に説明する。
図１は従来のファン取付装置の配置を示す要部断面図、図２は本発明によるファン取付装置の一実施例を示す要部側断面図、図３は本発明のファン取付装置の一実施例を示す要部分解斜視図である。
本発明のファン取付装置は、図１に示すように、天板１上方に屋根２を、前面開口３ａに扉４を備え、内部にカメラ制御盤等の電子機器５を収容して戸外に設置される屋根付き収容箱３の内部の熱を同収容箱３の天板１と屋根２との間に設けられた隙間から排気するためのファン６を同天板１に設けたファン取付孔１ａに取り付けるためのものである。
【００１３】
図２および図３において、
３１は略凸字状の取付枠であり、ファン取付孔１ａに嵌着する突出部３１ａの上方開口３１ａ１に防虫網３２を固定し、下部前端に挿通孔３１ｂ１を備える取付部３１ｂを下方に延出している。
この突出部３１ａはファン６を収容できる大きさとしている。
そして、この取付枠３１の下部後端には下方に延出する延出部３１ｃが設けられ、同延出部３１ｃには係止孔３１ｃ１が形成されている。
３３は前記取付枠３１の下方に配置される取付金具であり。
この取付金具３３は、前方に前記挿通孔３１ｂ１に対応するネジ孔３３ａ１を形成した固定部３３ａを設けている。
また、この取付金具３３の中央を下方に突出して凹状に形成し、同凹状部中央に前記突出部開口３１ａ１に対応する通風孔３３ｂ１を設け、同通風孔３３ｂ１周縁に前記ファン６を固定するネジ孔３３ｂ２を有するファン取付板３３ｂを設けている。
そして、この取付金具３３のファン取付板３３ｂ後方には前記係止孔３１ｃ１に係合する係止用突起３４ａを形成した係止板３４が設けられている。
【００１４】
以上の構成において、つぎにその組立手順を説明する。
まず、取付金具３３のファン取付板３３ｂの上にファン６を載置し、ファン６の取付孔６ａからファン取付板３３ｂのネジ孔３３ｂ２にネジ２０を螺着して固定する。
一方、天板１のファン取付孔１ａに取付枠３１の突出部３１ａを嵌着して固定する。
つぎに、前記ファン６を固定した取付金具３３の係止用突起３４ａを取付枠３１の係止孔３１ｃ１に係合してファン取付孔１ａに嵌着した取付枠３１の下側に取付金具３３を配置し、この取付枠３１の取付部３１ｂに有する挿通孔３１ｂ１から取付金具３３の固定部３３ａに有するネジ孔３３ｂ２にネジ２１を螺合して取付金具３３を取付枠３１に固定する。
このとき、前記取付部３１ｂの挿通孔３１ｂ１、および、固定部３３ａのネジ孔３３ｂ２は収容箱３の前面に向けて設けられており、前方から後方に向けてスクリュードライバを操作することができ、取り付けが簡単である。
【００１５】
【発明の効果】
以上説明したように、本発明によるファン取付装置によれば、ファン取付孔に嵌着する突出部の上方を開口し、下部前端に挿通孔を備える取付部を下方に延出した略凸字状の取付枠と、同取付枠の下方に配置され、前方に同挿通孔に対応するネジ孔を形成した固定部を、中央に前記突出部開口に対応する通風孔を設け、同通風孔周縁に前記ファンを固定するネジ孔を有するファン取付板を備えた取付金具とでなるので、ファンを固定した前記取付金具を取付枠の下方に配置した後、収容箱前方から後方に向けてスクリュードライバを操作することにより、取付枠の挿通孔から取付金具の固定部に備えるネジ孔にネジを螺合して取付金具を取付枠に固定するので、前記収容箱の前面から取付作業ができ、取付金具の下方にスクリュードライバの入る余地を設けなくともよく、また、取付枠の突出部が、ファンを収容する寸法に形成されているので、ファンを天板の上方屋根側に突き出して配置することができ、収容箱の外形寸法を大きくしなくとも、その有効容積を大きくすることができる。
