【発明の属する技術分野】
本発明は、天井面または壁面に設けられる換気口等に設置される換気装置の取付装置に関する。
【０００２】
【従来の技術】
近年、社会的な省エネルギー指向の高まりや、住環境の快適性の追求から、建物の高気密、高断熱化が進んでおり、このような建物に対する換気の必要性にともない、室内側、または室外側に数多くの換気口が設けられ、この換気口に取り付けられる換気装置を容易に設置できる換気装置の取付装置が要望されている。
【０００３】
従来、この種の換気装置の取付装置の一例として特開平８−２５４３４１号公報に示されるものが知られていた。以下、その構成を図６および図７を参照しながら説明する。
【０００４】
図に示すように、天井面１０１に設けた取付孔１０２に挿入され、下部に天井面１０１の下面に当接するフランジ１０３を形成し、上部にはダクト接続部１０４を設けた本体枠１０５の外周に凹状の溝部１０６を複数設け、凹状の溝部１０６の奥壁部１０７には凹状の溝部１０６より左右に突出し幅広となる凹部１０８を形成し、一端に押さえ部１０９ａを有し、ほぼＬ字状に形成された取付具１０９の他端に凹部１０８に係合して取付金具１０９の傾倒支点となる凸部１０９ｂを設け、凹部１０８と凸部１０９ｂによる支持手段１１０を形成し、この支持手段１１０を介して取付金具１０９が起立状態または横伏せ状態に傾倒自在になるように設けていた。
【０００５】
また、支持手段１１０により支持された取付金具１０９のほぼ中央部分には取付金具１０９の長手方向に長孔１０９ｃを形成し、本体枠１０５に形成された凹状の溝部１０６の下部に室内側から回動操作できるボルト１１１を取付金具１０９の長孔１０９ｃを通して凹状の溝部１０６内に配設されるように回動自在に支持し、ボルト１１１の端部より凹部の溝部１０６の側壁１１２に当接して回動が阻止される方形のナットよりなる可動体１１３をボルト１１１を回動して螺合し、ボルト１１１に保持して可動体１１３を可動する可動手段１１４を形成していた。
【０００６】
【発明が解決しようとする課題】
このような従来の換気装置の取付装置では、本体を天井面などの取付面に取り付けるときには、可動手段のボルトを操作して可動体を取付金具より遠ざけた位置に移動させ、取付金具を手などで起立させた状態で、本体枠を取付面に設けた取付孔内に挿入させなければならず、取付作業がしにくいという課題があった。
【０００７】
また、可動手段を構成するために、数多くの構成要素を必要とするとともに、本体枠の外周部に凹部の溝部をはじめとした構成要素を形成するため、本体の形状が複雑になるという課題があった。
【０００８】
本発明は上記課題を解決するもので、取付作業が容易で、本体の形状を簡易化した換気装置の取付装置を提供することを目的とする。
【０００９】
【課題を解決するための手段】
本発明の換気装置の取付装置においては、前後に開口を有し、取付面の取付孔に挿入される筒部を設け、前記筒部の端部に外方に突出し、前記取付面に当接するフランジ部を設けた本体の取付装置であって、前記フランジ部を前面側から前記筒部側に貫通するねじと、このねじの前記筒部側に螺合保持される取付具とを備え、前記取付具の螺合部から離れた他端側に前記取付面を押さえる押さえ部を設けるとともに、前記フランジ部の前面側から前記ねじを締め付けることにより、前記取付孔の内側面に当接させて前記取付具の回動を規制し、この回動を前記フランジ部方向の摺動に変え、前記取付面に前記押さえ部を圧接させる回動規制部を前記螺合部と前記押さえ部の間に介在させて設けた構成としたものである。
【００１０】
この本発明によれば、本体を取付孔に挿入設置するときに、取付具を手で保持する必要がないとともに、本体の形状を簡易化した換気装置の取付装置を提供することができる。
【００１１】
【発明の実施の形態】
本発明の請求項１記載の発明は、前後に開口を有し、取付面の取付孔に挿入される筒部を設け、前記筒部の端部に外方に突出し、前記取付面に当接するフランジ部を設けた本体の取付装置であって、前記フランジ部を前面側から前記筒部側に貫通するねじと、このねじの前記筒部側に螺合保持される取付具とを備え、前記取付具の螺合部から離れた他端側に前記取付面を押さえる押さえ部を設けるとともに、前記フランジ部の前面側から前記ねじを締め付けることにより、前記取付孔の内側面に当接させて前記取付具の回動を規制し、この回動を前記フランジ部方向の摺動に変え、前記取付面に前記押さえ部を圧接させる回動規制部を前記螺合部と前記押さえ部の間に介在させて設けた構成としたものであり、本体を取付孔に挿入設置するときに、取付具を手で保持する必要がないとともに、本体の形状を簡易化できるという作用を有する。
【００１２】
以下、本発明の実施の形態について、図１〜図５を参照しながら説明する。
【００１３】
（実施形態１）
図１および図２に示すように、前後にそれぞれ開口１１、１２を設け、室内の天井面または建物の軒天面などの取付面１に開口した取付孔２に挿入される筒部３を設け、筒部３の下端部に外方に突出し、取付面１の下面に当接するフランジ部４を設けた本体５と、フランジ部４の下方からフランジ部４を貫通するねじ１０の筒部３側に、一端側に設けた螺合部７を介して螺合保持する複数の取付具６と、この取付具６の螺合部７から離れた他端側に、本体５を取付孔２に挿入設置したとき、取付面１の上面を押さえて本体５を固定する押さえ部８とを備え、螺合部７と押さえ部８はフランジ部４と平行に設けられ、螺合部７と押さえ部８は、それぞれについて直角となる回動規制部９により連結される。また、ねじ１０のフランジ部４の上面側には、ねじ１０が下方に脱落しないように環状の抜け止め１０ａを設ける。また、フランジ部４の下面にはグリル（図示せず）が覆うように設けられ、筒部３の前後に設けた開口１１、１２と連通し、通風路を形成する。
【００１４】
上記構成において、換気装置となる本体５を取付面１に取り付けるときには、取付具６をねじ１０の反締付け方向に回動させて筒部３の外表面に当接させ、この状態で筒部３の外形および取付具６の幅面６ａが挿入できる大きさの取付孔２を取付面１に開口し、フランジ部４等を手で持って下方から取付孔２内に本体５をフランジ部４の上面が取付面１の下面に当接するまで挿入する。そして、手でフランジ部４等の下面を支え、下方よりねじ１０を締付け方向に回すと、筒部３に当接していた取付具６が締付け方向に回り、回動規制部９が取付孔２の内側端面に当たったところで締付け方向の回動が規制され、さらにねじ１０を締めると、取付具６は、取付孔２の内周面に回動規制部９が締付け方向に保持されながら螺合部７を介して下方に摺動され、押さえ部８が取付面１の上面に圧接し、取付面１をフランジ部４と取付具６の先端に配設した押さえ部８により狭持するようにして本体５を取付面１に取り付けることとなる。
【００１５】
なお、取付具６は、板状の金属を折り曲げて形成したもの、二つ以上の部品を結合して形成したもの、または、ある一定以上の硬度を有する樹脂で成形したものであってもよく、その作用効果に差異がないことはいうまでもない。
【００１６】
また、取付面１は、下方から取り付けられる天井面または建物の軒天面だけでなく、横方向から取り付けられる室内または屋外の壁面であってもよく、その作用効果に差異は生じない。
【００１７】
このように本発明の実施の形態１の換気装置の取付装置によれば、ねじ１０を締め付けることにより、取付具６の押さえ部８と螺合部７の間に、取付孔２の内側面に当接させて取付具６の回動を摺動に変える回動規制部９を介在させたので、事前に取付具６を反締付け方向に回して筒部３に当接させた状態で、取付孔２に本体５を挿入することで、手などで取付具６を保持しながら挿入するという手間が必要なく、高所等での取付作業が容易となる。
【００１８】
また、少ない部品点数で構成できて、本体５の筒部３に取付手段となる構成要素を形成する必要がないので、低コストであり、本体５の形状を簡易化でき、樹脂成形品ばかりでなく金属でも本体５を形成することができる。
【００１９】
また、取付具６は容易に着脱できるので、壁の厚さに応じて取付具を付け替えることで、様々な壁厚に適用できる汎用性の高い換気装置を低コストで得ることができる。
【００２０】
（実施形態２）
図３に示すように、前後にそれぞれ開口１１、１２を設け、室内の天井面または建物の軒天面などの取付面１に開口した取付孔２に挿入される筒部３を設け、筒部３の下端部に外方に突出し、取付面１の下面に当接するフランジ部４を設けた本体５と、フランジ部４の下方からフランジ部４を貫通するねじ１０の筒部３側に、一端側に設けた螺合部７を介して螺合保持する複数の取付具６Ａと、取付具６Ａの螺合部７から離れた他端側に、本体５を取付孔２に挿入設置したとき、取付面１の上面を押さえて本体５を固定する押さえ部８と、取付具６Ａの反押さえ部側の端部に、取付具６Ａを締付け方向にある一定量回すと筒部３の外周面に沿って当接する形状の回動規制片１３とを備え、ねじ１０のフランジ部４の上面側には、ねじ１０が下方に脱落しないように環状の抜け止め１０ａを設け、フランジ部４の下面にはグリル（図示せず）が覆うように設けられ、筒部３の前後に設けた開口１１、１２と連通し、通風路を形成する。
【００２１】
上記構成において、換気装置となる本体５を取付面１に取り付けるときには、取付具６Ａをねじ１０の反締付け方向に回動させて筒部３の外表面に当接させ、この状態で筒部３の外形および取付具６Ａの幅面６ａが挿入できる大きさの取付孔２を取付面１に開口し、フランジ部４等を手で持って下方から取付孔２内に本体５をフランジ部４の上面が取付面１の下面に当接するまで挿入する。そして、手でフランジ部４等の下面を支え、下方よりねじ１０を締付け方向に回すと、筒部３に当接していた取付具６Ａが締付け方向に回り、回動規制片１３が筒部３の外表面に沿うように当たったところで締付け方向の回動が規制され、さらにねじ１０を締めると、取付具６Ａは、筒部３の外表面に回動規制片１３が締付け方向に保持されながら螺合部７を介して下方に摺動され、押さえ部８が取付面１の上面に圧接し、取付面１をフランジ部４と取付具６Ａの先端に配設した押さえ部８により狭持するようにして本体５を取付面１に取り付けることとなる。
【００２２】
このように本発明の実施の形態２の換気装置の取付装置によれば、取付具６Ａの反押さえ部側の端部に、取付具６Ａを締付け方向にある一定量回すと筒部３に当接する回動規制片１３を設けたので、筒部３の外表面に取付具６Ａの回動を規制する構成要素を設けることなく、簡易な形状の筒部３と、簡易な形状の取付具６Ａとによって、取付具６Ａの回動を確実に規制することができる。
【００２３】
また、回動規制片１３を、ねじ１０を締め付けたとき筒部３の外周面に沿って当接するよう形成したので、さらにねじ１０を締め付けて取付具６Ａをフランジ部４側に摺動させるときに、回動規制片１３の保持力が増し、摺動動作を安定させることができる。
【００２４】
（実施形態３）
図４に示すように、取付具６Ｂに、ねじ１０を締め付けたとき、その幅面１４が筒部３の外周面に当接するように端部を略９０°回転させた回動規制片１３Ａを形成する。
【００２５】
上記構成において、本体５をフランジ部４の上面が取付面（図示せず）の下面に当接するまで取付孔（図示せず）内に挿入した後、フランジ部４の下方からねじ１０を締付け方向に回すと、筒部３に当接させた取付具６Ｂが締付け方向に回り、回動規制片１３Ａに形成した幅面１４が筒部３の外表面に当たったところで締付け方向の回動が規制され、さらにねじ１０を締めると、幅面１４は締付け方向に保持されながら筒部３の外周面を下方に摺動することにより、取付具６Ｂが安定した動作で下方に摺動することになる。
【００２６】
なお、回動規制片１３Ａは、板材を曲げたものであるが、取付具６Ｂの端部に別の部品を溶接等で接合して形成したり、所定以上の硬度を有する樹脂成形品で形成したりしてもその作用効果に差異はない。
【００２７】
このように本発明の実施の形態３の換気装置の取付装置によれば、取付具６Ｂの回動規制がより確実になり、取付具６Ｂの摺動をより安定させることができる。
【００２８】
（実施形態４）
図５に示すように、取付具６Ｃを締付け方向に回動させることにより、回動規制片１３Ｂの板厚面と当接するようにフランジ部４Ａに上方に折曲させた突出部１５を設ける。
【００２９】
上記構成において、筒部３の外形が、当接対象物の仕上がり形状が芳しくないときに当接時に隙間を生じ易い円筒形状であるときには、当接対象物である回動規制部１３Ｂには、安定した摺動ができるように高い寸法精度が求められるが、フランジ部４Ａに形成した突出部１５を簡易な形状にしておけば、これと当接させる回動規制部１３Ｂも簡易な形状にでき、高い寸法精度を必要としないことになる。
【００３０】
このように本発明の実施の形態４の換気装置の取付装置によれば、筒部３の外周面に安定した摺動をするための寸法精度を要しない回動規制片１３Ｂにすることができる。
【００３１】
【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、前後に開口を有し、取付面の取付孔に挿入される筒部を設け、前記筒部の端部に外方に突出し、前記取付面に当接するフランジ部を設けた本体の取付装置であって、前記フランジ部を前面側から前記筒部側に貫通するねじと、このねじの前記筒部側に螺合保持される取付具とを備え、前記取付具の螺合部から離れた他端側に前記取付面を押さえる押さえ部を設けるとともに、前記フランジ部の前面側から前記ねじを締め付けることにより、前記取付孔の内側面に当接させて前記取付具の回動を規制し、この回動を前記フランジ部方向の摺動に変え、前記取付面に前記押さえ部を圧接させる回動規制部を前記螺合部と前記押さえ部の間に介在させて設けたので、事前に取付具を反締付け方向に回して筒部に当接させた状態で、取付孔に本体を挿入することで、手などで取付具を保持しながら挿入するという手間が必要なく、高所等での取付作業が容易となる。
【００３２】
また、少ない部品点数で構成できて、本体の筒部に取付手段となる構成要素を形成する必要がないので、低コストであり、本体の形状を簡易化でき、樹脂成形品ばかりでなく金属でも本体を形成することができる。

When the main body is inserted and installed in the mounting hole In, together with no need to hold the fixture by hand, it has the effect of the shape of the body can be simplified.
[0012]
Hereinafter, embodiments of the present invention will be described with reference to FIGS.
[0013]
(Embodiment 1)
As shown in FIGS. 1 and 2, openings 11 and 12 are provided on the front and rear sides, respectively, and a cylindrical portion 3 is provided which is inserted into a mounting hole 2 opened on a mounting surface 1 such as an indoor ceiling surface or an eaves top surface of a building. The main body 5 provided with a flange portion 4 projecting outward at the lower end portion of the cylindrical portion 3 and contacting the lower surface of the mounting surface 1, and the cylindrical portion 3 side of the screw 10 penetrating the flange portion 4 from below the flange portion 4 A plurality of fixtures 6 that are screwed and held via a screwing portion 7 provided on one end side, and a main body 5 is inserted into the mounting hole 2 on the other end side away from the screwing portion 7 of the fixture 6. When installed, it includes a pressing part 8 that presses the upper surface of the mounting surface 1 and fixes the main body 5. The screwing part 7 and the pressing part 8 are provided in parallel with the flange part 4, and the screwing part 7 and the pressing part 8. Are connected by a rotation restricting portion 9 that is perpendicular to each other. Further, an annular retaining 10a is provided on the upper surface side of the flange portion 4 of the screw 10 so that the screw 10 does not fall down. A flange (not shown) is provided on the lower surface of the flange portion 4 so as to cover it, and communicates with the openings 11 and 12 provided at the front and rear of the cylindrical portion 3 to form a ventilation path.
[0014]
In the above configuration, when the main body 5 serving as a ventilation device is attached to the attachment surface 1, the attachment 6 is rotated in the counter-tightening direction of the screw 10 to contact the outer surface of the cylinder portion 3, and in this state, the cylinder portion 3. The attachment hole 2 having a size that allows the insertion of the outer surface of the attachment 6 and the width surface 6a of the attachment 6 is opened in the attachment surface 1, and the main body 5 is inserted into the attachment hole 2 from below by holding the flange portion 4 and the like by hand. Is inserted until it contacts the lower surface of the mounting surface 1. When the lower surface of the flange portion 4 or the like is supported by hand and the screw 10 is turned in the tightening direction from below, the fixture 6 that has been in contact with the tube portion 3 rotates in the tightening direction, and the rotation restricting portion 9 becomes the mounting hole 2. When the screw 10 is further tightened, the attachment 6 is screwed together while the rotation restricting portion 9 is held in the tightening direction on the inner peripheral surface of the attachment hole 2. The holding portion 8 is slid downward through the portion 7 so that the holding portion 8 is pressed against the upper surface of the mounting surface 1, and the mounting surface 1 is held by the holding portion 8 disposed at the distal end of the flange portion 4 and the fixture 6. Thus, the main body 5 is attached to the attachment surface 1.
[0015]
The fixture 6 may be formed by bending a plate-shaped metal, formed by combining two or more parts, or molded by a resin having a certain hardness or more. Needless to say, there is no difference in the effects.
[0016]
Moreover, the attachment surface 1 may be not only a ceiling surface or a building eaves surface attached from below, but also an indoor or outdoor wall surface attached from the lateral direction, and there is no difference in its operational effect.
[0017]
Thus, according to the attachment device for a ventilation device of Embodiment 1 of the present invention, by tightening the screw 10, the inner surface of the attachment hole 2 is interposed between the pressing portion 8 and the screwing portion 7 of the attachment 6. Since the rotation restricting portion 9 that changes the rotation of the fixture 6 to slide is interposed, the attachment 6 is rotated in the anti-clamping direction in advance and is attached to the tube portion 3. By inserting the main body 5 into the hole 2, there is no need to insert the main body 5 while holding the mounting tool 6 with a hand or the like, and attachment work at a high place or the like is facilitated.
[0018]
In addition, since it can be configured with a small number of parts and it is not necessary to form a component as an attachment means on the cylindrical portion 3 of the main body 5, it is low-cost, the shape of the main body 5 can be simplified, and only a resin molded product can be used.
