【発明の属する技術分野】
本発明は、壁部等に設けた換気扇取付孔に換気扇本体に設けたうちわボルトを進退させて取り付けるようにした換気扇に関する。
【0002】
【従来の技術】
近年、環境の良化を図るために設置される換気扇の普及に伴い、コストの安い換気扇への要求が更に高まってきている。
【0003】
従来、この種の換気扇の一例として図9に示すものが知られていた。以下、その構成について図9を参照しながら説明する。
【0004】
図に示すように、枠状のフレーム1019内部にファンモータ102を設けた換気扇本体103の室外側には室外側開口104を開閉する複数枚のシャッター105を、シャッター連結板106を介しスイッチ107と連動するように設け、室内側には風胴となるオリフィス108を設け、フレーム101の上方側フレーム101aには内側に向かい円形状に凹ませた円形凹部109を形成し、円形凹部109には、うちわボルト110が進退自在に螺合される大径部111aを有した、円筒状のナット111を圧入する円形孔112を設け、円筒状のナット111を円形孔112に圧入して、うちわボルト110の螺合する部分を構成し、壁部113等に設けた換気扇取付孔114にうちわボルト110の先端部を係合して換気扇本体103を換気扇取付孔114に取り付けていた。
【0005】
【発明が解決しようとする課題】
このような従来の換気扇では、上方側フレーム101aに形成した円形孔112に円筒状のナット111を圧入し、円筒状のナット111の回り止めおよび、上下方向の固定を大径部111aで行っていたため、円筒状のナット111は一端に大径部111aを有した特殊なナットを使用する必要があるとともに、円筒状のナット111を圧入して固定するための円形孔112の寸法精度および、円筒状のナット111の部品精度を高くする必要があり、コストが高くなるという課題があった。
【0006】
本発明は、上記課題を解決するもので、標準的な多角形ナットを使用することによってコストの低減を図ることのできる換気扇を提供することを目的とする。
【0007】
【課題を解決するための手段】
本発明の換気扇においては、換気扇本体を形成する枠状のフレームと、この枠状のフレームの上方側フレームに両側に切り込みを入れ内側に向けほぼU字状に凹ませ、左右が開口した収納部を形成した受部と、この受部の収納部の左または右の開口から挿入し、回動が阻止されるように収納され、少なくとも互いに平行な1組の辺を有する多角形ナットと、この多角形ナットに螺合されるうちわボルトが挿通するように前記受部の底部に設けた挿通孔とを備え、前記多角形ナットに進退自在に螺合したうちわボルトの先端部を壁部などに設けた換気扇取付孔に係合し、前記換気扇本体を取り付ける構成としたものである。
【0008】
この本発明によれば、標準的な多角形ナットを使用することによってコストの低減を図ることのできる換気扇を提供することができる。
【0009】
【発明の実施の形態】
本発明の請求項1に記載の発明は、換気扇本体を形成する枠状のフレームと、この枠状のフレームの上方側フレームに、内側に向け凹ませ上部が開口した受部と、この受部挿入し回動が阻止されるように収納され、少なくとも互いに平行な1組の辺を有する多角形ナットと、この多角形ナットに螺合されるうちわボルトが挿通するように前記受部の底部に設けた挿通孔とを備え、前記多角形ナットに進退自在に螺合したうちわボルトの先端部を壁部等に設けた換気扇取付孔に係合し、前記換気扇本体を取り付ける構成とした換気扇であって、前記受部は、前記上方側フレームに前記多角形ナットが収納されるように設けた収納凹部と、この収納凹部に連設し、前記多角形ナットが横動自在の形状で、前記多角形ナットの上面が保持される保持片を有した保持凹部とにより長方形状に形成されたものであり、受部に収納される多角形ナットは、標準的な多角形ナットを使用することが可能となり、取付部分の精度および部品精度を高くする必要がなくなるとともに、多角形ナットは、多角形ナット自体を横動することにより上方側フレームに設けた受部で回動が阻止された状態で保持されることとなるので、嵌合時のような寸法精度を要する必要がなく、コストの低減を図ることができるという作用を有する。
【0010】
以下、本発明の実施の形態について、図1〜図8を参照しながら説明する。
【0011】
(実施の形態1)
図1および図2に示すように、枠状のフレーム1の内部にファン2aをファンモータ2に着脱自在に設けた換気扇本体3の室外側には室外側開口4を開閉する複数のシャッター5をシャッター連結板6を介しスイッチ7と連動するように設け、室内側に風胴となるオリフィス8を枠状のフレーム1に着脱自在に設け、枠状のフレーム1の上方側フレーム1aに両側に切り込みを入れ、内側に向けほぼU字状に凹ませ、上部と左右が開口した収納部9を設けた受部10を形成し、受部10の収納部9の左または右の開口から挿入し、受部10により回動が阻止されるように収納された四角ナット11に螺合されるうちわボルト12のボルト部分が挿通される挿通孔13を受部10の底部14に設け、換気扇本体3の上方側フレーム1aに設けた受部10上の収納部9に四角ナット11を収納し、上方側フレーム1aの内側からうちわボルト12のボルト部分を受部10の底部14に設けた挿通孔13に挿通し、四角ナット11に螺合した状態に換気扇本体3を構成する。
【0012】
上記構成において、換気扇本体3を壁部15に設けた換気扇取付孔16に取り付けるときには、オリフィス8および、ファンモータ2に設けたファン2aを取り外し、換気扇取付孔16に換気扇本体3を装着し、換気扇本体3の内側よりうちわボルト12を操作し、うちわボルト12の先端を換気扇取付孔16に係合し固定したのち、オリフィス8を枠状のフレーム1に取り付け、ファン2aをファンモータ2に取り付けて取付けを完了する。
【0013】
なお、四角ナット11は、その形状に限定されるものでなく、六角ナットなど少なくとも互いに平行な1組の辺を有する形状のナットであればよく、その作用効果に差異はない。
【0014】
このように本発明の実施の形態1の換気扇によれば、換気扇本体3の上方側フレーム1aの両側に切り込みを入れ内側に向けほぼU字状に凹ませ、上部左右が開口した収納部9を形成した受部10の収納部9に四角ナット11を回動を阻止した状態に保持し、上方側フレーム1aの内側よりうちわボルト12を四角ナット11に螺合しているので、うちわボルト12に螺合されるナットとして標準の四角ナット11を使用することが可能となるとともに、四角ナット11は圧入等により固定する必要もなくなり、四角ナット11の収納される受部10部分の寸法精度を高める必要もなくなり、コスト低減を図ることができる。
【0015】
(実施の形態2)
図3および図4に示すように、換気扇本体3Aの上方側フレーム16に四角ナット11が収納されるように設けた収納凹部17と、収納凹部17に連設し、四角ナット11が横動自在な形状の保持凹部18とを長方形状に形成した受部10Aを設け、受部10Aの保持凹部18の側壁の一部を切り起こし、保持凹部18の上部に、四角ナット11の上面に当接し四角ナット11を保持するようにほぼ水平状の一対の保持方19を設ける。
【0016】
上記構成において、うちわボルト12を換気扇本体3Aの上方側フレーム1bに取り付けるときには、受部10Aの一方に形成した収納凹部17に四角ナット11を収納したのち、四角ナット11を横動して四角ナット11を保持凹部18側に移動することにより保持凹部18の上部に設けた保持片19が四角ナット11の上面に当接して四角ナット11が保持されることとなり、うちわボルト12のボルト部分は受部10Aの底部14に設けた挿通孔13を挿通し四角ナット11に螺合してうちわボルト12を四角ナット11に取り付けられる
このように本発明の実施の形態2の換気扇によれば、上方側フレーム16に四角ナット11の収納凹部17と、この収納凹部17に連接し、四角ナット11が横動できる保持凹部18とを設け、保持凹部18に四角ナット11の上面に当接し保持する保持片19を設けた受部10Aにより構成したので、標準的な四角ナット11を使用することができるとともに、四角ナット11は四角ナット11自体を横動することにより上方側フレーム1bに設けた受部10Aで回動が阻止された状態で保持されることとなるので、嵌合時のような寸法精度を要する必要がなくコストの低減を図ることができる。
【0017】
(実施の形態3)
図5および図6に示すように、四角ナット11を収納凹部17より保持凹部18に横動したときに、四角ナットが収納凹部17側に戻らないように阻止する阻止片20を受部10Bの底部14に起立自在となるように切り起こし形成する。
【0018】
上記構成において、収納凹部17に収納された四角ナット11を阻止片20が起立しようとする弾性に抗して保持凹部18側に横動したときには、四角ナット11の上面は保持片19により保持され、阻止片20が起立して四角ナット11の収納凹部17側の側面に対応し、四角ナットが収納凹部17側に移動するのが阻止され四角ナット11が保持されることとなる。
【0019】
このように本発明の実施の形態3の換気扇によれば、受部10Bに設けた収納凹部17に収納した四角ナット11を保持凹部18に横動したときに、四角ナット11が収納凹部17側に戻るのを阻止する阻止片20を設けたので、使用される四角ナット11は標準品を使用することができるとともに、四角ナット11は圧入等により固定する必要がないので、四角ナット11の保持部分の寸法精度を高くする必要もなくコストを低減することができる。また、保持凹部18内の四角ナット11は、保持片19と阻止片20により移動が阻止された状態で保持されることとなり、四角ナット11を固定した状態と同様にうちわボルト12が確実に保持される。
【0020】
(実施の形態4)
図7および図8に示すように、上方側フレーム1Cに四角ナット11が収納されるように凹ませた受部10Cと、この受部10Cの両側の上方側フレーム1C部分を切り起こし形成した起立状態の上部押え片21とを設け、受部10C内に収納された四角ナット11を上部押え片21を曲折させて押さえ保持する構成とする。
【0021】
上記構成において、四角ナット11を受部10C内に収納したのち、上部押え片21を曲折させて四角ナット11の上面を押さえ、四角ナット11を保持したのち、うちわボルト12を四角ナット11に螺合し、うちわボルト12を取り付ける。
【0022】
このように本発明の実施の形態4の換気扇によれば、四角ナット11が収納される受部10Cの両側に起立状態の上部押え片21を設け、受部10C内に四角ナット11を収納したのち、四角ナット11の上面を押さえるように上部押え片21を曲折して四角ナット11を保持するので、四角ナット11は受部10C内に収納されたのち、保持力調整の加工が行われ、四角ナット11の厚みにばらつきがあった場合においても四角ナット11を確実に固定状態に保持されることとなり、四角ナット11は標準品を使用することが可能となるとともに、四角ナット11の保持部分の寸法精度を高める必要もなく、また、四角ナット11を横動する必要もないので、自動化にも対応することができ、製造が容易でコスト低減を図ることができる。
【0023】
【発明の効果】
以上の実施の形態から明らかなように、本発明によれば、換気扇本体を形成する枠状のフレームと、この枠状のフレームの上方側フレームに両側に切り込みを入れ内側に向けほぼU字状に凹ませ、左右が開口した収納部を形成した受部と、この受部の収納部の左または右の開口から挿入し回動が阻止されるように収納され、少なくとも互いに平行な1組の辺を有する多角形ナットと、この多角形ナットに螺合されるうちわボルトが挿通するように前記受部の底部に設けた挿通孔とを備え、前記多角形ナットに進退自在に螺合したうちわボルトの先端部を壁部等に設けた換気扇取付孔に係合し、前記換気扇本体を取り付ける構成としたので、標準的な角形ナットを使用することによってコストの低減を図ることのできる換気扇を提供できる。
【0024】
また、上方側フレームに多角形ナットが収納されるように設けた収納凹部と、この収納凹部に連設し、前記多角形ナットが横動自在の形状で、多角形ナットの上面が保持される保持片を有した保持凹部とにより長方形状に形成される受部を設けたので、標準的な多角形ナットの使用が可能となるとともに、嵌合時のような寸法精度を要する必要がなくコストの低減を図ることができる。
【0025】
また、多角形ナットを収納凹部より保持凹部に移動したときに多角形ナットが収納したので、多角形ナットを固定した状態と同様に多角形ナットおよびうちわボルトを保持することができる。

And the fan bolt 12 is attached.
[0022]
Thus, according to the ventilation fan of Embodiment 4 of this invention, the upper holding piece 21 of the standing state was provided in the both sides of the receiving part 10C in which the square nut 11 is accommodated, and the square nut 11 was accommodated in the receiving part 10C. After that, the upper holding piece 21 is bent so as to hold the upper surface of the square nut 11 and the square nut 11 is held, so that the square nut 11 is accommodated in the receiving portion 10C, and the holding force is adjusted. Even when the thickness of the square nut 11 varies, the square nut 11 is securely held in a fixed state, and the square nut 11 can be used as a standard product, and the holding portion of the square nut 11 can be used. Therefore, it is not necessary to increase the dimensional accuracy, and it is not necessary to laterally move the square nut 11. Therefore, automation can be supported, manufacturing is easy, and cost can be reduced.

【The invention's effect】
As apparent from the above embodiments, according to the present invention, the frame-shaped frame forming the ventilation fan main body, and the upper frame of the frame-shaped frame are cut into both sides and substantially U-shaped toward the inside. A receiving part formed with a receiving part that is open to the left and right, and a receiving part that is inserted from the left or right opening of the receiving part of the receiving part so as to be prevented from rotating, and is at least one set parallel to each other A round fan that includes a polygonal nut having a side and an insertion hole provided in the bottom of the receiving part so that a round bolt bolted into the polygonal nut is inserted, and is screwed into the polygonal nut so as to freely advance and retract. Since the end of the bolt is engaged with the ventilation fan mounting hole provided on the wall, etc., and the ventilation fan body is mounted, a ventilation fan that can reduce costs by using a standard square nut is provided. it can.
[0024]
Also, a storage recess provided in the upper frame so that the polygon nut is stored, and a continuous connection to the storage recess so that the polygon nut can move laterally and the upper surface of the polygon nut is held. Since a receiving part formed in a rectangular shape is provided by a holding recess with a holding piece, a standard polygonal nut can be used, and it is not necessary to have dimensional accuracy at the time of fitting and cost Can be reduced.
[0025]
Further, since the polygon nut is accommodated when the polygon nut is moved from the accommodation recess to the holding recess, the polygon nut and the fan bolt can be retained in the same manner as the polygon nut is fixed.
