Description

【０００１】
【発明の属する技術分野】
本発明は、例えばスピーカ装置や監視カメラ装置、投光器等の各種機器を、天井や壁面、柱等に取り付けるのに用いる機器取付具に関する。
【０００２】
【従来の技術】
上記のような機器取付具として、従来、例えば図１０に示すようなスピーカ装置用取付具が知られている。この取付具は、図示しない例えば箱型スピーカ装置を天井等に取り付けることを前提とするもので、同図に示すように、天井側に固定される概略平板状の天井側固定部１０１と、スピーカ装置側に固定される概略平板状のスピーカ側固定部１０２と、を備えている。
【０００３】
天井側固定部１０１の一面（同図において下方側の面）には、その中央部分から略垂直方向に向かって伸延する概略円柱状のアーム部１０３が結合されている。そして、このアーム部１０３の先端には、概略円盤状の連結部１０４が、その平面部分をアーム部１０３の伸延方向に沿わせた状態で、結合されている。一方、スピーカ側固定部１０２の一面（同図において上方側の面）にも、その中央部分から略垂直方向に向かって伸延する概略円柱状のアーム部１０５が結合されている。そして、このアーム部１０５の先端にも、概略円盤状の連結部１０６が、その平面部分をアーム部１０５の伸延方向に沿わせた状態で、結合されている。
【０００４】
上記各連結部１０４、１０６は、それぞれの一面を互いに対向させた状態で、角度調整用ネジ１０７により結合されている。これにより、各固定部１０１、１０２、各アーム部１０３、１０５、各連結部１０４、１０６及び角度調整用ネジ１０７から成るこの取付具は、全体として一体化された構造となっている。そして、この角度調整用ネジ１０７を少し緩めると、同図に矢印１０８で示すように、当該角度調整用ネジ１０７を中心軸とする周方向において、各アーム部１０３、１０５の連結角度を調整できる。そして、この角度調整用ネジ１０７を強固に締め直すと、当該調整後の各アーム部１０３、１０５の連結角度を維持できる。なお、この角度調整用ネジ１０７は、飽くまで上記角度調整を行うためのものであって、任意に取り外すことを前提とするものではない。従って、本取付具は、基本的に、常に一体化された状態で使用される。
【０００５】
上記のように構成された取付具を用いて、例えば天井にスピーカ装置を取り付けるには、次の手順による。まず、設置対象箇所である天井に対して、天井側固定部１０１の他面側（アーム部１０３が結合されていない側の面）を対向させ、この状態で、当該天井側固定部１０１の一面側からこの天井側固定部１０１自体に穿設されたネジ挿通用貫通孔１０９、１０９、・・・を介して、図示しない固定用ネジを天井に螺着し、これによって当該天井側固定部１０１を天井に固定する。次に、スピーカ側固定部１０２の他面側（アーム部１０５が結合されていない側の面）に対して、取付対象となるスピーカ装置の筐体取付面を対向させ、この状態で、当該スピーカ側固定部１０２の一面側からこのスピーカ側固定部１０２に穿設されたネジ挿通用貫通孔１１０、１１０を介して、図示しないスピーカ取付ネジを、スピーカ装置の筐体に設けられたネジ孔に螺着する。これにより、当該スピーカ側固定部１０２にスピーカ装置を固定する。そして、上記角度調整用ネジ１０７を少し緩めて、各アーム部１０３、１０５の連結角度、即ち天井に対するスピーカ装置の取付角度、を希望の角度に調整する。そして、この調整後、角度調整用ネジ１０７を強固に締め直して、一連の取付作業を完了する。
【０００６】
【発明が解決しようとする課題】
しかし、上記従来の取付具によれば、天井側に固定される天井側固定部１０１と、スピーカ装置側に固定されるスピーカ側固定部１０２とが、一体化されているので、次のような問題がある。即ち、天井に固定された取付具に対して、スピーカ装置を取り付ける際、天井付近という所謂高所において、スピーカ装置を支持しながら、当該スピーカ装置に設けられたネジ孔に上記スピーカ取付ネジを螺着しなければならず、この作業が極めて困難であるという問題がある。特に、スピーカ装置は、その構造上、重量が比較的に大きいため、この問題が、より顕著となる。
【０００７】
また、上記とは反対に、まず先にスピーカ装置を取付具に固定し、その後で、これらスピーカ装置と取付具とを一体化したものを天井に固定する、ということも可能である。しかし、この場合、スピーカ装置と取付具とを一体化することにより更に重くなったものを天井位置にまで持ち上げなければならず、上記のように取付具のみを先に天井に固定する場合に比べて、多大な労力を要する。その上、この更に重くなったものを高所で支持しながら、上記固定用ネジを天井に螺着しなければならないので、上記問題が、より一層顕著になる。また、上記固定用ネジを螺着する際に、既にこの取付具（スピーカ側固定部１０２）に固定されているスピーカ装置自体（筐体）が、当該螺着作業の邪魔になる、という新たな問題も生じる。
【０００８】
更に、上記従来の取付具によれば、上記矢印１０８で示す方向においてスピーカ装置の天井に対する取付角度を調整できるものの、それ以外の方向においては、当該取付角度を調整することができない。従って、スピーカ装置の取付角度について、より自由な調整が要求される用途等において、十分な対応を取ることができない、という問題もある。
【０００９】
そこで、本発明は、スピーカ装置等の機器の取付作業が極めて容易で、かつ、当該機器の取付角度をより自由に調整できる機器取付具を提供することを目的とする。また、このような機器取付具を比較的に簡単な構造で実現することも、本発明の目的とするところである。
【００１０】
【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、本発明は、例えば天井や壁面、柱等の設置対象箇所に取り付けられる設置対象側取付部材と、この設置対象側取付部材とは別個に設けられ取付対象となる機器に取り付けられる機器側取付部材と、を具備する。そして、これら各取付部材の少なくとも一方は、他方の取付部材に結合するための結合手段を有し、この結合手段は、各取付部材の結合状態と、この結合状態を解除して上記各取付部材をそれぞれ分離可能とする非結合状態と、を任意に形成可能とされたものである。なお、ここで言う上記機器としては、例えばスピーカ装置や監視カメラ装置、或いは投光器等の各種機器がある。
【００１１】
即ち、本発明によれば、設置対象側取付部材と機器側取付部材という、それぞれ別個独立した２つの取付部材を具備する。そして、これら各取付部材は、所定の結合手段により、任意に結合され、または非結合とされる。結合状態においては、各取付部材は、一体化される。一方、非結合状態においては、各取付部材は、それぞれ分離可能とされる。
【００１２】
このように構成された本発明の機器取付具を用いて、任意の設置対象箇所、例えば天井、に対して、任意の機器、例えばスピーカ装置、を取り付けるには、次の手順による。即ち、まず、各取付部材を非結合状態とする。そして、この状態で、設置対象側取付部材のみを、例えば上記固定用ネジ等の所定の固定手段により、天井に取り付ける。これと同時に、機器取付部材のみを、例えば上記スピーカ取付ネジ等の所定の固定手段により、スピーカ装置（詳しくは、スピーカ装置の筐体取付面）に取り付ける。そして、天井に取り付けられた設置対象側取付部材に、スピーカ装置が取り付けられた機器側取付部材を、上記結合手段により結合する。これにより、一連の取付作業が完了する。
【００１３】
このように、本発明によれば、天井への設置対象側取付部材の取付作業と、スピーカ装置への機器側取付部材の取付作業とを、それぞれ別々に実施できる。そして、これら各取付部材を、所定の結合手段により結合するだけで、一連の取付作業を実現できる。従って、天井付近という高所においてスピーカ取付ネジを螺着しなければならない上述した従来技術とは異なり、当該面倒なネジの螺着作業を、例えば床上等の低所において、予め実施できる。このことは、監視カメラ装置や投光器等のスピーカ装置以外の機器を、天井に取り付ける場合も、同様である。また、壁面や柱等に各種機器を取り付ける場合も、同様である。
【００１４】
なお、上記他方の取付部材、特に設置対象側取付部材は、上記一方の取付部材、即ち機器側取付部材が、結合可能な部分を、複数有するよう構成してもよい。このように構成すれば、設置対象側取付部材に対する機器側取付部材の結合状態、即ち設置対象側取付部材に対する機器の結合位置や結合角度等を、任意に変更できる。また、１つの設置対象側取付部材に対して、複数の機器側取付部材、即ち複数の機器を、結合させることができる。
【００１５】
また、上記他方の取付部材は、棒状部を有し、上記一方の取付部材は、上記結合手段によりこの棒状部の長さ方向における任意の位置に結合可能な状態に構成されたものであってもよい。このように構成すれば、棒状部の長さ方向において、一方の取付部材の結合位置を任意に変更できる。また、棒状部に対して、一方の取付部材を複数結合させることもでき、例えば、一方の取付部材が機器取付部材である場合には、上記棒状部に対して複数の機器を取り付けることができる。
【００１６】
更に、棒状部は、その長さ方向において曲線状に形成された部分を有し、上記一方の取付部材は、この棒状部の曲線状に形成された部分にも結合可能としてもよい。このように構成すれば、棒状部の上記曲線状に形成された部分に沿って、一方の取付部材の結合位置を任意に変更でき、ひいては設置対象箇所に対する機器の取付角度を任意に変更できる。
【００１７】
また、一方の取付部材は、上記棒状部を中心軸とする周方向において当該棒状部の任意の位置に結合可能としてもよい。このようにすれば、棒状部を中心軸とする周方向において、当該棒状部に対する一方の取付部材の結合位置、即ち結合角度、を任意に変更でき、ひいては設置対象箇所に対する機器の取付角度を任意に変更できる。
【００１８】
そして、一方の取付部材は、上記棒状部が少なくともその一端から挿通可能な第１の貫通孔を有し、この第１の貫通孔内に棒状部を挿通させた状態で当該棒状部に結合するよう構成してもよい。このようにすれば、棒状部に対して、一方の取付部材を、より確実に結合することができる。また、棒状部に一方の取付部材を結合させる際に、この棒状部を上記第１の貫通孔に挿通させることにより、当該第１の貫通孔が一種の案内手段として作用するので、棒状部に対する一方の取付部材の結合作業が容易になる。
【００１９】
ここで、他方の取付部材が、例えば設置対象側取付部材である場合には、この設置対象側取付部材を設置対象箇所に取り付けたときに、上記棒状部の上記第１の貫通孔内に挿通される側の一端が、水平方向よりも上方側を向くよう構成するのが望ましい。このようにすれば、仮に上記結合手段による各取付部材の結合状態が緩和したとしても、上記棒状部は第１の貫通孔から抜けることはなく当該第１の貫通孔に挿通された状態にあるので、機器を含む機器側取付部材が落下することはない。従って、何らかの原因により、結合手段による各取付部材の結合状態が緩和したときに、機器側取付部が落下するのを防止できる。
【００２０】
これとは逆に、一方の取付部材が、設置対象側取付部材である場合には、次のようにするのが望ましい。即ち、この設置対象側取付部材を設置対象箇所に取り付けると共に、この設置対象側取付部材の上記第１の貫通孔内に機器側取付部材の棒状部を挿通させた状態でこれら各取付部材を結合したとき、当該棒状部の第１の貫通孔内に挿通された側の一端が、水平方向よりも下方側を向くように構成する。このように構成すれば、結合手段による各取付部材の結合状態が緩和したとしても、上記と同様、棒状部は第１の貫通孔から抜けることはなく当該第１の貫通孔に挿通された状態にあるので、機器を含む機器側取付部材が落下するのを防止できる。
【００２１】
なお、本発明における結合手段は、例えば、上記棒状部を挟持することにより当該棒状部に一方の取付部材を結合させる所謂挟持手段により構成できる。このように構成すれば、例えばネジ等の螺着手段により各取付部材を結合させる場合に比べて、各取付部材を容易に結合できる。
【００２２】
また、他方の取付部材は、上記棒状部を支持する支持手段を備えたものであってもよい。この場合、この支持手段は、上記棒状部を、その長さ方向における任意の位置で支持可能とするのが望ましい。このように構成すれば、棒状部の長さ方向において、他方の取付部材の結合位置をも任意に変更でき、ひいては、各取付部材相互の結合位置をより自由に変更できる。
【００２３】
ここで、棒状部が、その長さ方向において曲線状に形成された部分を有する場合には、上記支持手段は、この棒状部の曲線状に形成された部分においても当該棒状部を支持できるよう構成するのが望ましい。このように構成すれば、棒状部の上記曲線状に形成された部分に沿って、他方の取付部材（支持手段）による当該棒状部の支持位置を任意に変更でき、ひいては設置対象箇所に対する機器の取付角度を任意に変更できる。
【００２４】
また、上記支持手段は、棒状部を中心軸とする周方向において、当該棒状部の任意の位置を支持できるよう構成してもよい。このようにすれば、棒状部を中心軸とする周方向において、他方の取付部材による当該棒状部の支持位置を任意に変更でき、ひいては設置対象箇所に対する機器の取付角度を任意に変更できる。
【００２５】
そして、他方の取付部材は、上記棒状部が少なくともその一端から挿通可能な第２の貫通孔を有し、この第２の貫通孔内に棒状部を挿通させた状態で上記支持手段により当該棒状部を支持するよう構成してもよい。このようにすれば、支持手段によって棒状部をより確実に支持することができる。また、支持手段により棒状部を支持する際に、この棒状部を上記第２の貫通孔に挿通させることにより、当該第２の貫通孔が一種の案内手段として作用する。従って、支持手段により棒状部を支持する際の作業が、容易になる。
【００２６】
なお、上記支持手段は、例えば、上記棒状部を挟持することにより当該棒状部を支持する所謂挟持手段により構成できる。このように構成すれば、当該支持手段による棒状部の支持作業が、極めて容易になる。
【００２７】
また、上記のように第１及び第２の貫通孔を設けた場合には、棒状部の他端側がこれら各貫通孔内を挿通するのを防止するよう、当該棒状部の他端側に挿通防止手段を設けるのが望ましい。このようにすれば、上記結合手段による各取付部材の結合状態または上記支持手段による棒状部の支持状態が、何らかの原因により緩和したとしても、当該棒状部が上記第１及び第２の貫通孔から抜けるのを防止でき、ひいては機器を含む機器側取付部が落下するのを防止できる。
【００２８】
更に、上記棒状部は、その長さ方向に沿って、上記機器に接続される電線を収容可能な中空部を有するものとするのが望ましい。このように棒状部内を介して電線を配線するようにすれば、当該電線により本発明の取付具全体の美観が損なわれるのを防止でき、本発明の取付具を実際に設置対象箇所に取り付けたときの当該取付具全体の美装性を確保できる。
【００２９】
そして、上記中空部を設けた場合には、この中空部の内部と外部とを連通する状態に、上記電線が挿通可能な孔または溝を、棒状部の周壁に適宜設けるのが望ましい。このようにすれば、上記中空部内を介して配線される電線を、必要な箇所で外側に引き出すことができ、余計な配線経路を排除できる。
【００３０】
【発明の実施の形態】
本発明を例えばスピーカ装置用の取付具に応用する場合の一実施の形態について、図１から図９を参照して説明する。
【００３１】
図１は、本実施の形態の概略構成を示す図である。同図に示すように、本実施の形態は、湾曲した棒状部１１を有する設置対象側取付部材１と、当該棒状部１１が挿通可能な貫通孔２１、２１を有するスピーカ側取付部材２と、で構成されている。なお、後述するが、設置対象側取付部材１は、同図には示さない天井や壁面等の設置対象箇所に固定され、スピーカ側取付部材２は、同図には示さないスピーカ装置（詳しくは、このスピーカ装置の筐体取付面）に固定される。
【００３２】
図２に、設置対象側取付部材１の構造を、より詳細に示す。同図に示すように、上記棒状部１１は、その一端側のみが湾曲しており、他端側は略直線状であり、所謂概略釣針状に形成されている。そして、この棒状部１１の他端側であって、当該他端側の外周壁のうち上記湾曲している側とは反対側の部分に、概略平板状の固定部１２が、その一面を、当該外周壁に沿わせた状態で、結合されている。なお、これら棒状部１１及び固定部１２は、例えば鉄やステンレス等の金属により形成されており、これら両者の結合は、例えば溶接加工等により実現されている。勿論、これ以外にも、例えば樹脂や木質材等の非金属材料により棒状部１１及び固定部１２を形成し、これらをネジや接着剤等の溶接加工以外の結合手段により結合し或いは一体に形成してもよい。
【００３３】
固定部１２には、その一面側から他面側に貫通する状態に、複数、例えば４つ、のネジ挿通用貫通孔１３、１３、・・・が穿設されている。これら各ネジ挿通用貫通孔１３、１３、・・・は、この固定部１２を含む設置対象側取付部材１を、天井等に固定する際に用いる例えば木ネジ構成の固定用ネジ３、３、・・・を挿通させるためのものである。即ち、設置対象側取付部材１を天井等に固定する場合には、天井等に固定部１２の他面側（棒状部１１が結合されている側とは反対側の面）を対向させ、この状態で、固定部１２の一面側から各ネジ挿通用貫通孔１３、１３、・・・を介して、上記固定用ネジ３、３、・・・を天井に螺着する。
【００３４】
棒状部１１は、その一端から他端に至るまでその長さ方向を横切る断面形状及び断面積が略一様なパイプ状のもので、その中空部１４を介して、スピーカ装置に配線するための図示しない信号線等の電線を挿通できるように構成されている。また、この棒状部１１の湾曲している側の周壁には、当該棒状部１１の長さ方向に沿って、上記中空部１４の内部と外部とを連通するように溝１５が設けられている。そして、この溝１５を介して、中空部１４の内部と外部との間で上記電線を任意に挿通できるように構成されている。なお、この溝１５に代えて、上記電線を挿通可能な貫通孔を、棒状部１１の長さ方向に沿って、複数、穿設してもよい。
【００３５】
更に、棒状部１１の一端側は、上記湾曲の成す円周の２／３乃至３／４程度にまで比較的に大きく曲げられている。これにより、当該一端側の延長線が、棒状部の他端側若しくは当該他端側の延長線と、交差するよう構成されている。
【００３６】
一方、スピーカ側取付部材２は、図３に示すような構造となっている。なお、このスピーカ側取付部材２は、これを正面から見た構造と、背面から見た構造とが、同等とされており、また、左側から見た構造と、右側から見た構造とが、同等とされている。
【００３７】
同図に示すように、スピーカ側取付部材２は、内部が中空の概略直方形状の本体部２２を有している。そして、この本体部２２を構成する２組の対向側壁２３、２３及び２４、２４のうちの１組、例えば正面側と背面側とに位置する各側壁２３、２３に、それぞれ上記貫通孔２１、２１が互いに対向する状態に穿設されている。そして、他の１組（即ち左右）の各側壁２４、２４の下方側端縁には、それぞれ、これら各側壁２４、２４と垂直を成し、かつ、当該各側壁２４、２４から外方に向かって伸延する状態に、概略平板状の固定部２５、２５が結合されている。
【００３８】
上記各固定部２５、２５には、それぞれの一面側から他面側に貫通する状態に、ネジ挿通用貫通孔２６、２６が穿設されている。これら各ネジ挿通用貫通孔２６、２６は、各固定部２５、２５を含むスピーカ側取付部材２を、スピーカ装置に固定する際に用いる例えばボルト構成のスピーカ取付ネジ４、４を挿通させるためのものである。即ち、スピーカ側取付部材２をスピーカ装置に固定する場合には、スピーカ装置の筐体取付面に各固定部２５、２５の一面側（上記各側壁２４、２４が結合されている側とは反対側の面）を対向させ、この状態で、各固定部２５、２５の他面側から各ネジ挿通用貫通孔２６、２６を介して、上記スピーカ取付ネジ４、４を、スピーカ装置の筐体に設けられたネジ孔に螺着する。なお、各ネジ挿通用貫通孔２６、２６は、各固定部２５、２５が対向する方向に沿って伸延する長孔とされている。従って、これら各固定部２５、２５に固定されるスピーカ装置の型式等の違いによって、上記ネジ孔の間隔（ピッチ）が多少異なっても、或る程度、対応できる。
【００３９】
上記各側壁２３、２３及び２４、２４の各下方側端縁で囲まれる部分、所謂上記本体部２２の底面部分は、開口とされている。一方、本体部２２の上面側は、板状の上壁部２７によって閉鎖されており、この上壁部２７の各周縁に、上記各側壁２３、２３及び２４、２４の各上方側端縁が、それぞれ結合されている。更に、この上壁部２７の略中央部分には、その上面から底面に貫通する状態に雌ネジ部２８が形成されている。なお、これら各側壁２３、２３及び２４、２４と上壁部２７とから成る本体部２２と、各固定部２５、２５とから成る部分は、例えば１枚の金属板を板金加工することにより、一体に形成できる。勿論、これに限らず、例えば硬質樹脂等によっても、これらの部分を構成できる。
【００４０】
上記雌ネジ部２８には、これと螺合する状態に雄ネジ２９が挿入されている。この雄ネジ２９の上方側端部には、概略円盤状のツマミ部３０が結合されている。一方、雄ネジ２９の下方側端部が位置する側であって、上記本体部２２の内部には、下方側に向けて鋸歯状に形成された部分３１ａ、３１ａを有する押圧部３１が設けられている。この押圧部３１は、上記本体部２２を構成する各側壁２３、２３及び２４、２４の各内側面にそれぞれ沿う４つの平板部３１ｂ、３１ｂ及び３１ｃ、３１ｃと、これら各平板部３１ｂ、３１ｂ及び３１ｃ、３１ｃの各上方側端縁をそれぞれ結合する上方側平板部３１ｄと、から成り、例えば１枚の金属板を板金加工することにより一体に形成されている。そして、これら各平板部３１ｂ、３１ｂ及び３１ｃ、３１ｃのうち、上記各貫通孔２１、２１が設けられている側壁２３、２３の内側面に沿う各平板部３１ｂ、３１ｂの下方側端縁に、上記鋸歯状部分３１ａ、３１ａが、若干凹状の湾曲を成す状態に形成されている。また、他の平板部３１ｃ、３１ｃには、それぞれの外側面から内側面に向かってネジ３２、３２が螺着されている。更に、これら各ネジ３２、３２が螺着されている各平板部３１ｃ、３１ｃに沿う各側壁２４、２４には、当該各ネジ３２、３２の各頭部が緩やかに介在する状態に、上下方向に長い貫通孔、所謂長孔３３、３３が設けられている。
【００４１】
即ち、押圧部３１は、上記本体部２２を構成する各側壁２３、２３及び２４、２４の各内側面に、それぞれ各平板部３１ｂ、３１ｂ及び３１ｃ、３１ｃを沿わせた状態で、当該本体部２２内を上下方向に沿って摺動可能とされている。そして、この押圧部３１の摺動を案内すると共に、当該押圧部３１が本体部２２内から抜け出ないようにするために、上記のように各長孔３３、３３内に各ネジ３２、３２の各頭部を介在させている。また、上記構成から明らかなように、図３（ａ）に矢印３４で示すように、雄ネジ２９を中心軸としてその周方向にツマミ部３０を回動させると、同図（ａ）に矢印３５で示すように、当該雄ネジ２９が、上下方向に変位する。そして、上記ツマミ部３０を時計方向に回動させることにより下方に向けて雄ネジ２９を変位させると、図には示さないが、当該雄ネジ２９の下方側端部先端が、押圧部３１の上方側平板部３１ｄの上面に当接して、当該押圧部３１を下方に押圧する状態となる。
【００４２】
上記のように構成された設置対象側取付部材１とスピーカ側取付部材２とから成る本実施の形態の取付具を用いて、例えば天井にスピーカ装置を取り付けるには、次の手順による。即ち、まず、設置対象側取付部材１とスピーカ側取付部材２とを、それぞれ分離した状態（即ち、スピーカ側取付部材２の貫通孔２１、２１から設置対象側取付部材１の棒状部１１を引き抜いた状態）で、上記固定用ネジ３、３、・・・により、天井に設置対象側取付部材１のみを固定する。これと同時に、上記スピーカ取付ネジ４、４により、スピーカ装置の筐体取付面にスピーカ側取付部材２のみを固定する。そして、スピーカ装置が固定されたスピーカ側取付部材２を、天井に固定された上記設置対象側取付部材１の設置箇所にまで持ち上げて、当該スピーカ側取付部材２の貫通孔２１、２１内に、設置対象側取付部材１の棒状部１１を、挿通させる。
【００４３】
この状態で、スピーカ側取付部材２の上記ツマミ部３０を例えば時計回りに回動させると、押圧部３１の鋸歯状部分３１ａ、３１ａが、棒状部１の外周壁に当接する。そして、更にツマミ部３０を同一方向に回動させると、棒状部１が、上記押圧部３１の鋸歯状部分３１ａ、３１ａと、各貫通孔２１、２１の各内周壁のうち当該鋸歯状部分３１ａ、３１ａと対向する側の部分とによって、挟持される状態となる。これによって、設置対象側取付部材１とスピーカ側取付部材２とが結合し、即ち、これら各取付部材１、２から成る本実施の形態の取付具を介して、スピーカ装置が天井に取り付けられる。なお、これら各取付部材１、２の結合状態を解除する場合には、上記ツマミ部３０を反時計回りに回動して、上記棒状部１１の挟持状態を十分に緩和させる。そして、この状態で、棒状部１１を上記各貫通孔２１、２１から引き抜けばよい。
【００４４】
このように、本実施の形態によれば、天井への設置対象側取付部材１の取付作業と、スピーカ装置へのスピーカ側取付部材２の取付作業とを、それぞれ別々に実施できる。そして、設置対象側取付部材１の棒状部１１を、スピーカ側取付部材２の貫通孔２１に挿通させて、上記ツマミ部３０を回動するだけで、一連の取付作業を実現できる。従って、天井付近という高所においてスピーカ取付ネジを螺着しなければならない上述した従来技術とは異なり、当該面倒なネジの螺着作業を、例えば床上等の低所において、予め実施できる。よって、上記従来技術に比べて、スピーカ装置の取付作業を、極めて容易に実施できる。このことは、本実施の形態の取付具を用いて、スピーカ装置を壁面や柱等に取り付ける場合も、同様である。
【００４５】
なお、上述したように、棒状部１１は、その長さ方向を横切る断面形状及び断面積が略一定である。従って、この棒状部１１が上記各貫通孔２１、２１内に挿通されている状態においては、例えば図１に矢印５、５で示すように、当該棒状部１１の長さ方向に沿って、スピーカ装置を含むスピーカ側取付部材２を任意に移動（摺動）させることができる。そして、この棒状部１１の長さ方向における任意の位置で、上記ツマミ部３０を時計回りに回動することにより、当該棒状部１１の湾曲した部分をも含む任意の位置にスピーカ側取付部材２を固定できる。
【００４６】
また、棒状部１１の長さ方向を横切る上記断面形状は、所謂円形であるので、この棒状部１１が各貫通孔２１、２１内に挿通されている状態においては、例えば図１に矢印６，６で示すように、棒状部１１を中心軸とする周方向において、スピーカ装置を含むスピーカ側取付部材２を任意に回動させることができる。そして、この棒状部１１の周方向における任意の位置で、上記ツマミ部３０を時計回りに回動することにより、当該任意の位置においてスピーカ側取付部材２を固定できる。
【００４７】
例えば、今、図４に示すように、本実施の形態の取付具を天井１０に取り付けるとする。この場合、同図に矢印５０で示すように、棒状部１１の長さ方向に沿って、棒状部１１に対するスピーカ装置７を含むスピーカ側取付部材２の固定位置を変更すれば、例えば同図に点線７ａで示すように、当該矢印５０で示す方向において、天井１０に対する上記スピーカ装置７の取付角度を任意に調整できる。そして、同図に矢印６０で示すように、棒状部１１を中心軸とする周方向において、この棒状部１１に対するスピーカ側取付部材２の固定位置を変更すれば、当該矢印６０で示す方向、即ち上記矢印５０で示す方向と空間的に直交する方向において、天井１０に対する上記スピーカ装置７の取付角度を任意に調整できる。従って、スピーカ装置の取付角度の調整が一方向にのみ限定される上述した従来技術とは異なり、様々な方向において、当該取付角度を任意に調整できる。
【００４８】
また、上記図４のように本実施の形態の取付具を天井１０に取り付けた場合には、棒状部１１の一端は、少なくとも、水平方向よりも上方側に向いた状態となる。これは、上述したように、棒状部１１の一端を延長した線と、棒状部１１の他端側または当該他端側を延長した線とが、交差する程度に、当該棒状部１１の一端側を大きく湾曲させているからである。従って、何らかの原因により上記ツマミ部３０が緩和したとしても（詳しくは、押圧部３１の鋸歯状部分３１ａ、３１ａと各貫通孔２１、２１の各内周壁とによる棒状部１１の挟持状態が緩和したとしても）、各貫通孔２１、２１内から棒状部１１が抜けることはない。よって、上記ツマミ部３０が緩むことによるスピーカ装置７の落下事故を防止できる。
【００４９】
更に、本実施の形態によれば、上述したように、棒状部１１内の中空部１４を介して、スピーカ装置７に接続される信号線等の電線が配線される。そして、この電線は、棒状部１１の周壁に設けられた溝１５を介して、任意の場所から外部に引き出すことができる。従って、棒状部１１のいずれの位置にスピーカ側取付部材２（スピーカ装置７）が取り付けられても、当該電線が外部に露出する部分を極力抑制することができる。従って、当該電線が外部に露出することにより、本実施の形態の取付具全体の美観が損なわれるのを防止できる。
【００５０】
そして、本実施の形態を構成する設置対象側取付部材１は、所謂金属パイプ製の棒状部１１に概略平板状の固定部１２を結合させるという、極めて簡単な構造のものである。一方、スピーカ側取付部材２は、所謂板金加工品である本体部２２、固定部２６、２６及び押圧部３１と、ツマミ部３０付きの雄ネジ２９及び２本のネジ３２、３２と、から成り、この構造もまた、極めて簡単である。従って、本実施の形態によれば、上記のような多大なる効果を奏する取付具を、極めて簡単かつ安価に実現できるという効果もある。
【００５１】
図５は、本実施の形態の取付具を、壁面２０に取り付けた状態を示す図である。なお、同図は、棒状部１１を略鉛直方向に沿わせた状態で、設置対象側取付部材１を壁面２０に取り付けた場合の図である。この場合も、上記図４の場合と同様に、例えば図５に矢印５１で示すように、棒状部１１の長さ方向に沿って、棒状部１１に対するスピーカ側取付部材２の固定位置を変更すれば、例えば同図に点線７ｂで示すように、当該矢印５１で示す方向において、壁面２０に対するスピーカ装置７の取付角度を任意に調整できる。そして、同図に矢印６１で示すように、棒状部１１を中心軸とする周方向において、この棒状部１１に対するスピーカ側取付部材２の固定位置を変更すれば、当該矢印６１で示す方向において、壁面２０に対する上記スピーカ装置７の取付角度を任意に調整できる。また、この場合も、棒状部１１の一端が、水平方向よりも上方側に向いた状態となるので、上記ツマミ部３０が緩むことによるスピーカ装置７の落下事故を防止できる。
【００５２】
図６は、棒状部１１を略水平方向に沿わせた状態で、設置対象側取付部材１を壁面２０に取り付けた場合の図である。この場合も、同図に矢印５２で示すように、棒状部１１の長さ方向に沿って、棒状部１１に対するスピーカ側取付部材２の固定位置を変更すれば、矢印５２で示す方向において、壁面２０に対するスピーカ装置７の取付角度を任意に調整できる。そして、同図に矢印６２で示すように、棒状部１１を中心軸とする周方向において、この棒状部１１に対するスピーカ側取付部材２の固定位置を変更すれば、同図に点線７ｃで示すように、当該矢印６２で示す方向において、壁面２０に対するスピーカ装置７の取付角度を任意に調整できる。
【００５３】
本実施の形態においては、図７（ａ）に示すように、設置対象側取付部材１を構成する固定部１２に代えて、スピーカ側取付部材２と全く同様の構造の取付部材２ａを用い、この取付部材２ａに設けられた貫通孔２１ａ、２１ａ内に棒状部１１を挿通させた状態で当該棒状部１１を挟持するよう構成してもよい。このようにすれば、同図（ａ）に矢印７０で示すように、取付部材２ａによる棒状部１１の挟持位置、換言すればこの取付部材２ａを介しての天井１０等に対する棒状部１１の固定位置を、当該棒状部１１の長さ方向において、任意に変更できる。また、上記各貫通孔２１ａ、２１ａの各中心を通る線を中心軸として、同図（ｂ）に矢印８０で示す方向に、棒状部１１を任意に回動できる。従って，同図（ｂ）に点線７ｂ、７ｂで示すように、上記矢印８０で示す方向においても、天井１０等の設置対象箇所に対するスピーカ装置７の取付角度を、任意に調整できる。
【００５４】
なお、上記のような取付部材２ａを用いる場合には、棒状部１１の他端側に、例えば上記各貫通孔２１ａ、２１ａよりも径の大きい円盤状のストッパ１６を設けるのが望ましい。このようにストッパ１６を設ければ、何らかの理由により上記取付部材２ａによる棒状部１１の挟持状態が緩和しても、この棒状部１１が貫通孔２１ａ、２１ａ内を抜けることはなく、即ちスピーカ装置７の落下事故を防止できる。なお、このストッパ１６は、各貫通孔２１ａ、２１ａを挿通不可能な構造であれば足り、上記円盤状の構造に限定されるものではない。
【００５５】
また、上記取付部材２ａを用いる場合には、棒状部１１として、例えば図８に示すように、それ全体が湾曲したものを用いてもよい。このようにすれば、棒状部１１の長さ方向に沿って、当該棒状部１１の上記取付部材２ａによる挟持位置を変更することによっても、天井１０等に対するスピーカ装置７の取付角度を調整できる。従って、当該角度調整を、より詳細に実現できる。
【００５６】
更に、棒状部１１に対しては、スピーカ装置７を含むスピーカ側取付部材２を、複数、結合させることもできる。また、例えば図９に示すように、棒状部１１の他端側についても、その一端側と同様の構造とすることにより、１つ棒状部１１（設置対象側取付部材１）に対して、より多くのスピーカ装置７、７を取り付けることもできる。
【００５７】
本実施の形態においては、スピーカ装置を取付対象とする場合について説明したが、これに限らない。例えば、監視カメラ装置や投光器等のスピーカ装置以外の各種機器を、天井等に取り付ける場合にも、本発明を応用できる。
【００５８】
また、図１において、スピーカ側取付部材２を天井等の設置対象側に取り付け、設置対象側取付部材１をスピーカ装置側に取り付けてもよい。なお、この場合、スピーカ側取付部材２を天井等に取り付け、このスピーカ側取付部材２の各貫通孔２１、２１内に設置対象側取付部材１の棒状部１１を挿入すると、当該設置対象側取付部材１の構造上、明らかに、棒状部１１の一端側が、水平方向よりも下方側を向くことが予想できる。従って、上記ツマミ部３０による棒状部１１の挟持状態が、何らかの原因により緩和したとしても、棒状部１１が各貫通孔２１、２１から抜けることはなく、スピーカ装置の落下事故を防止できる。
【００５９】
そして、棒状部１１の形状は、釣針状に限らない。例えば、棒状部１１の長さ方向に沿って、複数の湾曲部を設けたり、より複雑な曲線部分を設けてもよい。また、スピーカ側取付部材２を構成する押圧部３１の鋸歯状部分３１ａ、３１ａと貫通孔２１、２１の内周縁との間で棒状部１１を挟持することにより、当該スピーカ側取付部材２を棒状部１１に結合させたが、これ以外の方法により、これら両者を結合してもよい。そして、上記押圧部３１の鋸歯状部分３１ａ、３１ａに代えて、この部分にゴム等の緩衝性材料等を設けることにより、上記結合を確実にしてもよい。
【００６０】
更に、上記スピーカ側取付部材２の各貫通孔２１、２１に代えて、環状部分を設け、この環状部分に棒状部１１を挿通させた状態で、当該棒状部１１を挟持するよう構成してもよい。また、棒状部１１は、パイプ状のものに限らず、例えば角棒状のものであってもよい。即ち、本実施の形態で説明した構造は、飽くまで本発明の一例であって、本実施の形態と同様の作用及び効果を奏するのであれば、本実施の形態とは別の構造によって本発明を実現してもよい。
【００６１】
なお、本実施の形態において、スピーカ側取付部材２に穿設された各貫通孔２１、２１が、特許請求の範囲に記載の第１の貫通孔に対応する。そして、これら各貫通孔２１、２１内において、上記押圧部３１の鋸歯状部分３１ａ、３１ａとの間で棒状部１１を挟持する構造が、特許請求の範囲に記載の結合手段に対応する。
【００６２】
また、図７及び図８に示すように、上記スピーカ側取付部材２と同様の取付部材２ａにより棒状部１１を挟持する構造が、特許請求の範囲に記載の支持手段に対応する。そして、この取付部材２ａに穿設された貫通孔２１ａ、２１ａが、特許請求の範囲に記載の第２の貫通孔に対応する。
【００６３】
【発明の効果】
以上のように、本発明によれば、天井側に取り付けられる設置対象側取付部材と、スピーカ装置等の機器側に取り付けられる機器側取付部材と、がそれぞれ別個独立している。従って、例えば床上等の低所において、機器側取付部材に対する機器の取付作業を実施できるので、天井付近という所謂高所においてスピーカ装置等の取付作業（詳しくは、スピーカ取付ネジの螺着作業）を行わなければならない上述した従来技術に比べて、当該スピーカ装置等の機器の取付作業を極めて容易に実施できるという効果がある。また、様々な方向において、機器の取付角度を調整できるようにも構成できるので、当該機器の取付角度について自由な調整が要求される用途等において、上記従来技術よりも柔軟に対応できる。

BACKGROUND OF THE INVENTION
The present invention relates to a device fixture used for mounting various devices such as a speaker device, a monitoring camera device, and a projector to a ceiling, a wall surface, a pillar, or the like.
[0002]
[Prior art]
Conventionally, for example, a speaker device fixture as shown in FIG. 10 is known as the above-described device fixture. This fixture is based on the premise that, for example, a box-type speaker device (not shown) is attached to a ceiling or the like. As shown in the figure, a substantially flat plate-like ceiling-side fixing portion 101 fixed to the ceiling side, and a speaker. And a substantially flat speaker-side fixing portion 102 fixed to the apparatus side.
[0003]
A substantially columnar arm portion 103 extending from the central portion in a substantially vertical direction is coupled to one surface of the ceiling-side fixing portion 101 (a surface on the lower side in the figure). Then, a substantially disk-shaped connecting portion 104 is coupled to the tip of the arm portion 103 in a state in which the plane portion is along the extending direction of the arm portion 103. On the other hand, a substantially columnar arm portion 105 extending from the central portion in a substantially vertical direction is also coupled to one surface (upper surface in the figure) of the speaker side fixing portion 102. Further, a substantially disk-shaped connecting portion 106 is also coupled to the tip of the arm portion 105 in a state where the planar portion is along the extending direction of the arm portion 105.
[0004]
Each of the connecting portions 104 and 106 is coupled by an angle adjusting screw 107 with one surface thereof facing each other. As a result, the fixture including the fixing portions 101 and 102, the arm portions 103 and 105, the connecting portions 104 and 106, and the angle adjusting screw 107 has an integrated structure as a whole. When the angle adjusting screw 107 is slightly loosened, as shown by an arrow 108 in the figure, the connecting angle of the arm portions 103 and 105 can be adjusted in the circumferential direction with the angle adjusting screw 107 as the central axis. . When the angle adjusting screw 107 is firmly tightened, the connection angles of the arm portions 103 and 105 after the adjustment can be maintained. Note that the angle adjusting screw 107 is used to adjust the angle until it gets tired, and is not based on the assumption that it is arbitrarily removed. Therefore, this fixture is basically used in an always integrated state.
[0005]
In order to attach the speaker device to, for example, the ceiling using the fixture configured as described above, the following procedure is used. First, the other surface side of the ceiling side fixing portion 101 (the surface on which the arm portion 103 is not coupled) is opposed to the ceiling that is the installation target location, and in this state, one surface of the ceiling side fixing portion 101 A fixing screw (not shown) is screwed into the ceiling through screw insertion through holes 109, 109,... Drilled in the ceiling side fixing portion 101 itself from the side. To the ceiling. Next, the housing mounting surface of the speaker device to be mounted is opposed to the other surface side of the speaker side fixing portion 102 (the surface on which the arm portion 105 is not coupled), and in this state, the speaker A speaker mounting screw (not shown) is screwed into a screw hole provided in the housing of the speaker device through the screw insertion through holes 110 and 110 formed in the speaker side fixing portion 102 from one side of the side fixing portion 102. Screw it on. As a result, the speaker device is fixed to the speaker-side fixing unit 102. Then, the angle adjusting screw 107 is slightly loosened to adjust the connection angle of the arm portions 103 and 105, that is, the mounting angle of the speaker device with respect to the ceiling to a desired angle. After this adjustment, the angle adjusting screw 107 is firmly tightened to complete a series of mounting operations.
[0006]
[Problems to be solved by the invention]
However, according to the conventional fixture, the ceiling-side fixing portion 101 fixed to the ceiling side and the speaker-side fixing portion 102 fixed to the speaker device side are integrated. There's a problem. That is, when the speaker device is attached to the fixture fixed to the ceiling, the speaker mounting screw is screwed into a screw hole provided in the speaker device while supporting the speaker device at a so-called high position near the ceiling. There is a problem that this work is extremely difficult. In particular, since the speaker device has a relatively large weight due to its structure, this problem becomes more prominent.
[0007]
On the contrary, it is also possible to first fix the speaker device to the fixture first, and then fix the speaker device and the fixture integrated to the ceiling. However, in this case, it is necessary to lift the heavier one by integrating the speaker device and the fixture to the ceiling position, as compared with the case where only the fixture is fixed to the ceiling first as described above. It takes a lot of labor. In addition, the above problem becomes even more pronounced because the fixing screw must be screwed onto the ceiling while supporting the heavier one at a high place. Further, when the fixing screw is screwed, the speaker device itself (housing) that is already fixed to the fixture (speaker side fixing portion 102) becomes an obstacle to the screwing operation. Problems also arise.
[0008]
Furthermore, according to the conventional fixture, the mounting angle of the speaker device with respect to the ceiling can be adjusted in the direction indicated by the arrow 108, but the mounting angle cannot be adjusted in other directions. Therefore, there is also a problem that sufficient measures cannot be taken in applications that require more flexible adjustment of the mounting angle of the speaker device.
[0009]
Accordingly, an object of the present invention is to provide a device mounting tool that allows a mounting operation of a device such as a speaker device to be extremely easy and that allows the mounting angle of the device to be adjusted more freely. It is also an object of the present invention to realize such a device attachment with a relatively simple structure.
[0010]
[Means for Solving the Problems]
In order to achieve the above-described object, the present invention provides an installation object side mounting member that is attached to an installation target site such as a ceiling, a wall surface, or a pillar, and the installation object side mounting member that is provided separately as an installation object. A device-side attachment member attached to the device. At least one of each of the mounting members has a coupling means for coupling to the other mounting member. The coupling means releases the coupling state of each mounting member and releases the coupling state to each of the mounting members. Can be arbitrarily formed in a non-bonded state in which each can be separated. In addition, as said apparatus said here, there exist various apparatuses, such as a speaker apparatus, a surveillance camera apparatus, or a projector, for example.
[0011]
In other words, according to the present invention, there are provided two independent attachment members, that is, an installation object side attachment member and an equipment side attachment member. Each of these attachment members is arbitrarily coupled or uncoupled by a predetermined coupling means. In the coupled state, the mounting members are integrated. On the other hand, in the non-bonded state, each attachment member is separable.
[0012]
In order to attach an arbitrary device, for example, a speaker device, to an arbitrary installation target location, for example, a ceiling, using the device fixture of the present invention configured as described above, the following procedure is used. That is, first, each attachment member is brought into a non-coupled state. In this state, only the installation target side attachment member is attached to the ceiling by a predetermined fixing means such as the fixing screw. At the same time, only the device attachment member is attached to the speaker device (specifically, the housing attachment surface of the speaker device) by a predetermined fixing means such as the speaker attachment screw. And the apparatus side attachment member in which the speaker apparatus was attached to the installation object side attachment member attached to the ceiling is couple | bonded by the said coupling | bonding means. Thereby, a series of attachment work is completed.
[0013]
Thus, according to the present invention, the installation work of the installation target side mounting member to the ceiling and the installation work of the device side mounting member to the speaker device can be performed separately. And a series of attachment work is realizable only by couple | bonding each of these attachment members with a predetermined | prescribed coupling means. Therefore, unlike the above-described conventional technique in which the speaker mounting screw must be screwed in a high place near the ceiling, the troublesome screwing operation can be performed in advance in a low place such as on the floor. This is the same when a device other than a speaker device such as a monitoring camera device or a projector is mounted on the ceiling. The same applies when various devices are attached to a wall surface or a pillar.
[0014]
The other mounting member, particularly the installation target side mounting member, may be configured such that the one mounting member, that is, the device side mounting member, has a plurality of connectable portions. If comprised in this way, the coupling | bonding state of the apparatus side attachment member with respect to the installation object side attachment member, ie, the coupling position of the apparatus with respect to the installation object side attachment member, a coupling angle, etc. can be changed arbitrarily. In addition, a plurality of device-side mounting members, that is, a plurality of devices, can be coupled to one installation target-side mounting member.
[0015]
The other mounting member has a rod-shaped portion, and the one mounting member is configured to be coupled to an arbitrary position in the length direction of the rod-shaped portion by the coupling means. Also good. If comprised in this way, the coupling | bonding position of one attachment member can be changed arbitrarily in the length direction of a rod-shaped part. In addition, a plurality of one attachment members can be coupled to the rod-shaped portion. For example, when one attachment member is a device attachment member, a plurality of devices can be attached to the rod-shaped portion. .
[0016]
Further, the rod-shaped portion may have a portion formed in a curved shape in the length direction, and the one attachment member may be connectable to the curved portion of the rod-shaped portion. If comprised in this way, the coupling | bonding position of one attachment member can be changed arbitrarily along the part formed in the said curve shape of a rod-shaped part, and the attachment angle of the apparatus with respect to an installation object location can also be changed arbitrarily.
[0017]
Moreover, one attachment member is good also as coupling | bonding to the arbitrary positions of the said rod-shaped part in the circumferential direction centering on the said rod-shaped part. In this way, in the circumferential direction with the rod-shaped portion as the central axis, the coupling position of one mounting member with respect to the rod-shaped portion, that is, the coupling angle can be arbitrarily changed, and thus the device mounting angle with respect to the installation target location can be arbitrarily varied. Can be changed.
[0018]
And one attachment member has the 1st penetration hole in which the above-mentioned rod-like part can penetrate from at least the end, and couples to the rod-like part in the state where the rod-like part was inserted in this 1st penetration hole You may comprise. In this way, one attachment member can be more reliably coupled to the rod-shaped portion. Further, when one attachment member is coupled to the rod-like portion, the rod-like portion is inserted into the first through-hole so that the first through-hole acts as a kind of guide means. One attachment member can be easily joined.
[0019]
Here, when the other mounting member is, for example, an installation target side mounting member, the mounting target side mounting member is inserted into the first through hole of the rod-shaped portion when the installation target side mounting member is mounted to the installation target location. It is desirable that one end on the side to be used is configured to face upward with respect to the horizontal direction. If it does in this way, even if the coupling | bonding state of each attachment member by the said coupling | bonding means eases, the said rod-shaped part will be in the state penetrated by the said 1st through-hole, without escaping from the 1st through-hole. Therefore, the apparatus side attachment member including an apparatus does not fall. Therefore, it is possible to prevent the device-side mounting portion from dropping when the coupling state of the mounting members by the coupling means is relaxed for some reason.
[0020]
On the contrary, when one attachment member is an installation object side attachment member, it is desirable to do as follows. That is, the installation target side mounting member is attached to the installation target location, and the mounting members are coupled in a state where the rod-shaped portion of the device side mounting member is inserted into the first through hole of the installation target side mounting member. When it does, it comprises so that the end of the side penetrated in the 1st through-hole of the said rod-shaped part may face a lower side rather than a horizontal direction. If comprised in this way, even if the coupling | bonding state of each attachment member by a coupling | bonding means eases, the state which was inserted in the said 1st through-hole without the rod-shaped part coming out of the 1st through-hole similarly to the above Therefore, it is possible to prevent the device-side mounting member including the device from falling.
[0021]
The coupling means in the present invention can be constituted by, for example, so-called clamping means for coupling one mounting member to the rod-shaped portion by clamping the rod-shaped portion. If comprised in this way, compared with the case where each attachment member is couple | bonded by screwing means, such as a screw, for example, each attachment member can be couple | bonded easily.
[0022]
Further, the other mounting member may be provided with a supporting means for supporting the rod-shaped portion. In this case, it is desirable that the supporting means can support the rod-like portion at an arbitrary position in the length direction. If comprised in this way, the coupling | bonding position of the other attachment member can also be changed arbitrarily in the length direction of a rod-shaped part, and by extension, the coupling | bonding position of each attachment member can be changed more freely.
[0023]
Here, in the case where the rod-shaped portion has a curved portion in the length direction, the support means can support the rod-shaped portion even in the curved portion of the rod-shaped portion. It is desirable to configure. If comprised in this way, the support position of the said rod-shaped part by the other attachment member (support means) can be changed arbitrarily along the part formed in the said curve shape of a rod-shaped part, and by extension, the apparatus with respect to the installation object location The mounting angle can be changed arbitrarily.
[0024]
Further, the support means may be configured to support an arbitrary position of the rod-shaped portion in the circumferential direction with the rod-shaped portion as the central axis. If it does in this way, the support position of the said rod-shaped part by the other attachment member can be changed arbitrarily in the circumferential direction which makes a rod-shaped part a central axis, and the attachment angle of the apparatus with respect to an installation object location can also be changed arbitrarily.
[0025]
The other mounting member has a second through-hole through which the rod-shaped portion can be inserted from at least one end thereof, and the rod-shaped portion is inserted into the second through-hole by the support means. You may comprise so that a part may be supported. If it does in this way, a rod-shaped part can be more reliably supported by a support means. Further, when the rod-shaped portion is supported by the support means, the second through-hole acts as a kind of guide means by inserting the rod-shaped portion through the second through-hole. Therefore, the operation | work at the time of supporting a rod-shaped part with a support means becomes easy.
[0026]
In addition, the said support means can be comprised by what is called a clamping means which supports the said rod-shaped part by clamping the said rod-shaped part, for example. If comprised in this way, the support operation | work of the rod-shaped part by the said support means will become very easy.
[0027]
Further, when the first and second through holes are provided as described above, the other end side of the rod-shaped portion is inserted into the other end side of the rod-shaped portion so as to prevent the other end side of the rod-shaped portion from being inserted through each through hole. It is desirable to provide a prevention means. In this way, even if the coupling state of each mounting member by the coupling means or the support state of the rod-shaped part by the support means is relieved for some reason, the rod-shaped part is removed from the first and second through holes. It is possible to prevent the device from being detached, and in turn, to prevent the device-side mounting portion including the device from falling.
[0028]
Furthermore, it is desirable that the rod-shaped portion has a hollow portion capable of accommodating an electric wire connected to the device along its length direction. If the electric wire is wired through the inside of the rod-like portion in this way, it can be prevented that the aesthetic appearance of the entire fixture of the present invention is impaired by the electric wire, and the fixture of the present invention is actually attached to the installation target location. The appearance of the entire fixture can be ensured.
[0029]
And when the said hollow part is provided, it is desirable to provide suitably the hole or groove | channel which can insert the said electric wire in the state which connects the inside and this exterior of this hollow part in the surrounding wall of a rod-shaped part. If it does in this way, the electric wire wired via the inside of the above-mentioned hollow part can be pulled out outside in a required part, and an extra wiring route can be excluded.
[0030]

May be.
[0033]
A plurality of, for example, four screw insertion through holes 13, 13,... Are formed in the fixing portion 12 so as to penetrate from the one surface side to the other surface side. These through holes for screw insertion 13, 13,... Are used when fixing the installation target side mounting member 1 including the fixing portion 12 to a ceiling or the like, for example, fixing screws 3, 3, It is for inserting ... That is, when fixing the installation target side mounting member 1 to the ceiling or the like, the other surface side of the fixing portion 12 (the surface opposite to the side where the rod-shaped portion 11 is coupled) is opposed to the ceiling or the like. In this state, the fixing screws 3, 3,... Are screwed onto the ceiling from the one surface side of the fixing part 12 through the screw insertion through holes 13, 13,.
[0034]
The rod-shaped portion 11 is a pipe-shaped portion having a substantially uniform cross-sectional shape and cross-sectional area that crosses the length direction from one end to the other end, and is used for wiring to the speaker device via the hollow portion 14. An electric wire such as a signal line (not shown) can be inserted. Further, a groove 15 is provided in the curved peripheral wall of the rod-shaped portion 11 so as to communicate the inside and the outside of the hollow portion 14 along the length direction of the rod-shaped portion 11. . And it is comprised so that the said electric wire can be arbitrarily inserted between the inside of the hollow part 14, and the exterior via this groove | channel 15. FIG. Instead of the groove 15, a plurality of through-holes through which the electric wire can be inserted may be formed along the length direction of the rod-shaped portion 11.
[0035]
Furthermore, one end side of the rod-like portion 11 is bent relatively large to about 2/3 to 3/4 of the circumference formed by the curve. Thereby, the extension line on the one end side is configured to intersect with the other end side of the rod-like portion or the extension line on the other end side.
[0036]
On the other hand, the speaker side mounting member 2 has a structure as shown in FIG. The speaker-side mounting member 2 has a structure that is viewed from the front and a structure that is viewed from the back, and the structure that is viewed from the left side and the structure that is viewed from the right side. It is considered equivalent.
[0037]
As shown in the figure, the speaker-side mounting member 2 has a substantially rectangular main body 22 having a hollow interior. And one set of the two opposing side walls 23, 23 and 24, 24 constituting the main body portion 22, for example, the side walls 23, 23 positioned on the front side and the back side, respectively, the through holes 21, 21 are drilled so as to face each other. The lower edge of each of the other pair of side walls 24, 24 is perpendicular to the side walls 24, 24 and outward from the side walls 24, 24. The substantially flat fixing parts 25, 25 are joined in a state of extending toward the front.
[0038]
In each of the fixing portions 25, 25, screw insertion through holes 26, 26 are formed so as to penetrate from the one surface side to the other surface side. These screw insertion through-holes 26 and 26 are used for inserting speaker mounting screws 4 and 4, for example, bolt configurations used when fixing the speaker side mounting member 2 including the fixing portions 25 and 25 to the speaker device. Is. That is, when the speaker side mounting member 2 is fixed to the speaker device, one surface side of each fixing portion 25, 25 (opposite to the side where the side walls 24, 24 are connected) to the housing mounting surface of the speaker device. In this state, the speaker mounting screws 4, 4 are connected from the other surface side of the fixing portions 25, 25 via the screw insertion through holes 26, 26. And screwed into the screw hole provided in. Each of the screw insertion through holes 26 and 26 is a long hole extending along a direction in which the fixing portions 25 and 25 face each other. Therefore, even if the spacing (pitch) of the screw holes is slightly different due to the difference in the model of the speaker device fixed to each of the fixing portions 25, 25, it can be handled to some extent.
[0039]
A portion surrounded by each lower side edge of each of the side walls 23, 23 and 24, 24, a so-called bottom portion of the main body portion 22 is an opening. On the other hand, the upper surface side of the main body portion 22 is closed by a plate-like upper wall portion 27, and the upper side edges of the side walls 23, 23 and 24, 24 are formed on the peripheral edges of the upper wall portion 27. , Each is coupled. Furthermore, a female screw portion 28 is formed in a substantially central portion of the upper wall portion 27 so as to penetrate from the top surface to the bottom surface. In addition, the part which consists of the main-body part 22 which consists of each of these side walls 23, 23 and 24, 24 and the upper wall part 27, and each fixing | fixed part 25, 25, for example by carrying out sheet metal processing of one metal plate, Can be formed integrally. Of course, the present invention is not limited to this, and these portions can be configured by, for example, a hard resin.
[0040]
A male screw 29 is inserted into the female screw portion 28 so as to be screwed therewith. A generally disc-shaped knob portion 30 is coupled to the upper end portion of the male screw 29. On the other hand, on the side where the lower end portion of the male screw 29 is located, a pressing portion 31 having portions 31a and 31a formed in a sawtooth shape toward the lower side is provided inside the main body portion 22. ing. The pressing portion 31 includes four flat plate portions 31b, 31b and 31c, 31c along the inner side surfaces of the side walls 23, 23 and 24, 24 constituting the main body portion 22, and the flat plate portions 31b, 31b and 31c, 31c, and the upper side flat plate part 31d which couple | bonds each upper side edge respectively, For example, it forms integrally by carrying out sheet-metal processing of one metal plate. And among these flat plate portions 31b, 31b and 31c, 31c, on the lower side edge of each flat plate portion 31b, 31b along the inner surface of the side walls 23, 23 provided with the respective through holes 21, 21, The serrated portions 31a and 31a are formed in a slightly concave curved state. In addition, screws 32, 32 are screwed onto the other flat plate portions 31c, 31c from the outer side surface toward the inner side surface. Further, the side walls 24 and 24 along the flat plate portions 31c and 31c to which the screws 32 and 32 are screwed are vertically moved so that the heads of the screws 32 and 32 are gently interposed. Long through holes, so-called long holes 33, 33 are provided.
[0041]
That is, the pressing portion 31 is in a state in which the flat plate portions 31b, 31b and 31c, 31c are along the inner side surfaces of the side walls 23, 23 and 24, 24 constituting the main body portion 22, respectively. The inside of 22 can be slid along the up-down direction. Then, in order to guide the sliding of the pressing portion 31 and prevent the pressing portion 31 from coming out of the main body portion 22, the screws 32, 32 are inserted into the long holes 33, 33 as described above. Each head is interposed. As is clear from the above configuration, as shown by an arrow 34 in FIG. 3 (a), when the knob portion 30 is rotated in the circumferential direction around the male screw 29 as a central axis, the arrow in FIG. As indicated by 35, the male screw 29 is displaced in the vertical direction. Then, when the male screw 29 is displaced downward by rotating the knob portion 30 in the clockwise direction, the lower end of the male screw 29 is arranged so that the tip of the pressing portion 31 is not shown in the drawing. It will contact | abut to the upper surface of 31 d of upper side flat plate parts, and will be in the state which presses the said press part 31 below.
[0042]
In order to attach the speaker device to the ceiling, for example, using the fixture of the present embodiment comprising the installation target side mounting member 1 and the speaker side mounting member 2 configured as described above, the following procedure is used. That is, first, the installation target side mounting member 1 and the speaker side mounting member 2 are separated from each other (that is, the rod-like portion 11 of the installation target side mounting member 1 is pulled out from the through holes 21 and 21 of the speaker side mounting member 2. In this state, only the installation target side mounting member 1 is fixed to the ceiling with the fixing screws 3, 3,. At the same time, only the speaker side mounting member 2 is fixed to the housing mounting surface of the speaker device by the speaker mounting screws 4 and 4. And the speaker side mounting member 2 to which the speaker device is fixed is lifted up to the installation location of the installation target side mounting member 1 fixed to the ceiling, and in the through holes 21 and 21 of the speaker side mounting member 2, The rod-shaped part 11 of the installation target side mounting member 1 is inserted.
[0043]
In this state, when the knob portion 30 of the speaker-side mounting member 2 is rotated, for example, clockwise, the sawtooth portions 31 a and 31 a of the pressing portion 31 abut against the outer peripheral wall of the rod-like portion 1. Further, when the knob portion 30 is further rotated in the same direction, the rod-like portion 1 becomes the sawtooth portion 31a of the pressing portion 31 and the serrated portion 31a of the inner peripheral walls of the through holes 21 and 21. , 31a and the part on the opposite side, is in a state of being sandwiched. As a result, the installation target side attachment member 1 and the speaker side attachment member 2 are coupled, that is, the speaker device is attached to the ceiling via the attachment of the present embodiment comprising the attachment members 1 and 2. In addition, when canceling | releasing the connection state of these each attachment members 1 and 2, the said knob part 30 is rotated counterclockwise, and the clamping state of the said rod-shaped part 11 is fully relieve | moderated. In this state, the rod-like portion 11 may be pulled out from the through holes 21 and 21.
[0044]
Thus, according to this Embodiment, the attachment operation | work of the installation object side attachment member 1 to a ceiling and the attachment operation | work of the speaker side attachment member 2 to a speaker apparatus can each be implemented separately. And a series of attachment work is realizable only by inserting the rod-shaped part 11 of the installation object side attachment member 1 in the through-hole 21 of the speaker side attachment member 2, and rotating the said knob part 30. FIG. Therefore, unlike the above-described conventional technique in which the speaker mounting screw must be screwed in a high place near the ceiling, the troublesome screwing operation can be performed in advance in a low place such as on the floor. Therefore, the mounting operation of the speaker device can be carried out very easily as compared with the prior art. The same applies to the case where the speaker device is attached to a wall surface, a pillar, or the like using the fixture of the present embodiment.
[0045]
In addition, as above-mentioned, the cross-sectional shape and cross-sectional area which cross the length direction of the rod-shaped part 11 are substantially constant. Therefore, in a state where the rod-shaped portion 11 is inserted into the through-holes 21 and 21, for example, as shown by arrows 5 and 5 in FIG. The speaker side mounting member 2 including the device can be arbitrarily moved (slided). Then, by rotating the knob portion 30 clockwise at an arbitrary position in the length direction of the rod-like portion 11, the speaker side mounting member 2 can be placed at an arbitrary position including the curved portion of the rod-like portion 11. Can be fixed.
[0046]
In addition, since the cross-sectional shape crossing the length direction of the rod-shaped portion 11 is a so-called circle, in the state where the rod-shaped portion 11 is inserted into the through holes 21, 21, for example, arrows 6 and 6 in FIG. 6, the speaker-side mounting member 2 including the speaker device can be arbitrarily rotated in the circumferential direction with the rod-shaped portion 11 as the central axis. And the speaker side attachment member 2 can be fixed in the said arbitrary position by rotating the said knob part 30 clockwise at the arbitrary positions in the circumferential direction of this rod-shaped part 11. FIG.
[0047]
For example, as shown in FIG. 4, it is assumed that the fixture of the present embodiment is attached to the ceiling 10 now. In this case, as shown by an arrow 50 in the figure, if the fixing position of the speaker side mounting member 2 including the speaker device 7 with respect to the rod-like part 11 is changed along the length direction of the rod-like part 11, for example, FIG. As indicated by the dotted line 7 a, the mounting angle of the speaker device 7 with respect to the ceiling 10 can be arbitrarily adjusted in the direction indicated by the arrow 50. Then, as shown by an arrow 60 in the figure, if the fixing position of the speaker side mounting member 2 with respect to the rod-shaped portion 11 is changed in the circumferential direction around the rod-shaped portion 11, the direction indicated by the arrow 60, that is, The mounting angle of the speaker device 7 with respect to the ceiling 10 can be arbitrarily adjusted in a direction that is spatially orthogonal to the direction indicated by the arrow 50. Therefore, unlike the above-described conventional technique in which the adjustment of the mounting angle of the speaker device is limited to only one direction, the mounting angle can be arbitrarily adjusted in various directions.
[0048]
Moreover, when the fixture of this Embodiment is attached to the ceiling 10 like the said FIG. 4, the end of the rod-shaped part 11 will be in the state which faced the upper side at least rather than the horizontal direction. As described above, this is because one end side of the rod-like portion 11 is such that the line extending from one end of the rod-like portion 11 intersects the other end side of the rod-like portion 11 or the line extending the other end side. This is because is greatly curved. Therefore, even if the knob portion 30 is relaxed for some reason (more specifically, the clamping state of the rod-like portion 11 by the serrated portions 31a and 31a of the pressing portion 31 and the inner peripheral walls of the through holes 21 and 21 is relaxed. However, the rod-shaped part 11 does not come out of the through holes 21 and 21. Therefore, the fall accident of the speaker apparatus 7 by the said knob part 30 loosening can be prevented.
[0049]
Furthermore, according to the present embodiment, as described above, an electric wire such as a signal line connected to the speaker device 7 is wired through the hollow portion 14 in the rod-like portion 11. And this electric wire can be pulled out from the arbitrary places through the groove | channel 15 provided in the surrounding wall of the rod-shaped part 11. FIG. Therefore, even if the speaker side attachment member 2 (speaker device 7) is attached to any position of the rod-like portion 11, the portion where the electric wire is exposed to the outside can be suppressed as much as possible. Therefore, it can prevent that the beauty | look of the whole fixture of this Embodiment is impaired by the said electric wire exposing outside.
[0050]
And the installation object side attachment member 1 which comprises this Embodiment is a thing of the very simple structure of couple | bonding the substantially flat fixing part 12 with the rod-shaped part 11 made from what is called a metal pipe. On the other hand, the speaker-side mounting member 2 includes a main body portion 22, a fixed portion 26, 26 and a pressing portion 31, which are so-called sheet metal products, a male screw 29 with a knob portion 30, and two screws 32, 32. This structure is also very simple. Therefore, according to the present embodiment, there is also an effect that the fixture having the great effects as described above can be realized extremely simply and inexpensively.
[0051]
FIG. 5 is a view showing a state in which the fixture of the present embodiment is attached to the wall surface 20. In addition, the figure is a figure at the time of attaching the installation object side attachment member 1 to the wall surface 20 in the state which put the rod-shaped part 11 along the substantially vertical direction. Also in this case, as in the case of FIG. 4, the fixing position of the speaker side mounting member 2 with respect to the rod-shaped portion 11 is changed along the length direction of the rod-shaped portion 11, for example, as indicated by an arrow 51 in FIG. 5. For example, the mounting angle of the speaker device 7 with respect to the wall surface 20 can be arbitrarily adjusted in the direction indicated by the arrow 51 as indicated by a dotted line 7b in FIG. Then, as shown by an arrow 61 in the same figure, if the fixing position of the speaker side mounting member 2 with respect to the rod-shaped portion 11 is changed in the circumferential direction with the rod-shaped portion 11 as the central axis, The mounting angle of the speaker device 7 with respect to the wall surface 20 can be arbitrarily adjusted. Also in this case, since one end of the rod-shaped portion 11 is directed upward from the horizontal direction, it is possible to prevent the speaker device 7 from being accidentally dropped due to loosening of the knob portion 30.
[0052]
FIG. 6 is a view when the installation target side attachment member 1 is attached to the wall surface 20 in a state in which the rod-like portion 11 is substantially horizontal. Also in this case, as shown by an arrow 52 in the figure, if the fixing position of the speaker side mounting member 2 with respect to the rod-like portion 11 is changed along the length direction of the rod-like portion 11, the wall surface in the direction shown by the arrow 52 is changed. The mounting angle of the speaker device 7 with respect to 20 can be arbitrarily adjusted. Then, as indicated by an arrow 62 in the figure, if the fixing position of the speaker side mounting member 2 with respect to the rod-shaped portion 11 is changed in the circumferential direction with the rod-shaped portion 11 as the central axis, as indicated by the dotted line 7c in the same figure. In addition, in the direction indicated by the arrow 62, the mounting angle of the speaker device 7 with respect to the wall surface 20 can be arbitrarily adjusted.
[0053]
In the present embodiment, as shown in FIG. 7A, instead of the fixing portion 12 constituting the installation target side mounting member 1, an mounting member 2a having the same structure as the speaker side mounting member 2 is used. You may comprise so that the said rod-shaped part 11 may be clamped in the state which inserted the rod-shaped part 11 in the through-holes 21a and 21a provided in this attachment member 2a. If it does in this way, as shown by the arrow 70 in the figure (a), the clamping position of the rod-shaped part 11 by the attachment member 2a, in other words, fixation of the rod-shaped part 11 with respect to the ceiling 10 etc. via this attachment member 2a The position can be arbitrarily changed in the length direction of the rod-like portion 11. Further, the rod-like portion 11 can be arbitrarily rotated in the direction indicated by the arrow 80 in FIG. 5B with the line passing through the centers of the through holes 21a and 21a as the central axis. Accordingly, the mounting angle of the speaker device 7 with respect to the installation target location such as the ceiling 10 can be arbitrarily adjusted in the direction indicated by the arrow 80 as indicated by dotted lines 7b and 7b in FIG.
[0054]
In addition, when using the attachment member 2a as described above, it is desirable to provide, for example, a disk-shaped stopper 16 having a diameter larger than that of each of the through holes 21a and 21a on the other end side of the rod-like portion 11. If the stopper 16 is provided in this way, even if the clamping state of the rod-shaped portion 11 by the mounting member 2a is eased for some reason, the rod-shaped portion 11 does not pass through the through holes 21a, 21a. 7 fall accidents can be prevented. The stopper 16 only needs to have a structure incapable of being inserted through the through holes 21a and 21a, and is not limited to the disk-shaped structure.
[0055]
Moreover, when using the said attachment member 2a, as shown in FIG. 8, as the rod-shaped part 11, you may use what was curved as a whole. If it does in this way, the attachment angle of the speaker apparatus 7 with respect to the ceiling 10 grade | etc., Can be adjusted also by changing the clamping position by the said attachment member 2a of the said rod-shaped part 11 along the length direction of the rod-shaped part 11. FIG. Therefore, the angle adjustment can be realized in more detail.
[0056]
Furthermore, a plurality of speaker side mounting members 2 including the speaker device 7 can be coupled to the rod-shaped portion 11. For example, as shown in FIG. 9, the other end side of the rod-like portion 11 is made to have the same structure as that of the one end side, thereby making it more possible to make one rod-like portion 11 (installation target side mounting member 1). Many speaker devices 7, 7 can also be attached.
[0057]
In the present embodiment, the case where the speaker device is an attachment target has been described, but the present invention is not limited to this. For example, the present invention can also be applied when various devices other than a speaker device such as a monitoring camera device and a projector are mounted on a ceiling or the like.
[0058]
Moreover, in FIG. 1, the speaker side attachment member 2 may be attached to the installation target side such as a ceiling, and the installation target side attachment member 1 may be attached to the speaker device side. In this case, when the speaker side mounting member 2 is mounted on the ceiling or the like, and the rod-like portion 11 of the installation target side mounting member 1 is inserted into each of the through holes 21 and 21 of the speaker side mounting member 2, the installation target side mounting is performed. Obviously, from the structure of the member 1, it can be expected that one end side of the rod-shaped portion 11 faces the lower side than the horizontal direction. Therefore, even if the holding state of the rod-shaped portion 11 by the knob portion 30 is alleviated for some reason, the rod-shaped portion 11 does not come out of the through holes 21 and 21, and an accidental fall of the speaker device can be prevented.
[0059]
And the shape of the rod-shaped part 11 is not restricted to a fishhook shape. For example, a plurality of curved portions or a more complicated curved portion may be provided along the length direction of the rod-shaped portion 11. Further, by sandwiching the rod-shaped portion 11 between the serrated portions 31a, 31a of the pressing portion 31 constituting the speaker-side mounting member 2 and the inner peripheral edges of the through holes 21, 21, the speaker-side mounting member 2 is shaped like a rod. Although it couple | bonded with the part 11, you may couple | bond both these by methods other than this. Then, instead of the saw-toothed portions 31a and 31a of the pressing portion 31, the coupling may be ensured by providing a buffering material such as rubber in this portion.
[0060]
Furthermore, it replaces with each through-holes 21 and 21 of the said speaker side attachment member 2, and it may comprise so that the said rod-shaped part 11 may be clamped in the state which provided the annular part and inserted the rod-shaped part 11 in this annular part. Good. Further, the rod-like portion 11 is not limited to a pipe-like shape, and may be, for example, a square-rod-like shape. In other words, the structure described in this embodiment is merely an example of the present invention, and the present invention is structured by a structure different from that of this embodiment as long as the same operations and effects as those of this embodiment are achieved. It may be realized.
[0061]
In the present embodiment, the through holes 21 and 21 formed in the speaker side mounting member 2 correspond to the first through holes described in the claims. And in each of these through-holes 21 and 21, the structure which clamps the rod-shaped part 11 between the serrated parts 31a and 31a of the said press part 31 respond | corresponds to the coupling means as described in a claim.
[0062]
Further, as shown in FIGS. 7 and 8, the structure in which the rod-like portion 11 is sandwiched by the attachment member 2a similar to the speaker-side attachment member 2 corresponds to the support means described in the claims. And the through-holes 21a and 21a drilled in this attachment member 2a respond | correspond to the 2nd through-hole as described in a claim.
[0063]
【The invention's effect】
As described above, according to the present invention, the installation target side mounting member attached to the ceiling side and the equipment side mounting member attached to the equipment side such as the speaker device are independent from each other. Accordingly, for example, the device can be mounted on the device-side mounting member in a low place such as on the floor, so that the speaker device or the like can be mounted in a so-called high place near the ceiling (specifically, a screwing operation of a speaker mounting screw). Compared with the above-described prior art that must be performed, there is an effect that the mounting operation of the apparatus such as the speaker device can be performed very easily. Moreover, since it can also comprise so that the attachment angle of an apparatus can be adjusted in various directions, it can respond | correspond more flexibly than the said prior art in the use etc. in which a free adjustment is required about the attachment angle of the said apparatus.
