１０は台部材で、棒状をなし長手の一端に被測定物２の側面４から突出して配置される突出部１１が形成されて適宜な重量を有する重りの機能を備え、被測定物２の上面３に要時に設置される。そして、突出部１１側を形成した主部材１２、主部材１２の反突出部１１側に配置された副部材１３及び上面に枢持軸が配置されて主部材１２に副部材１３を枢着した蝶番１４によって折り畳み可能に構成されている。
【００１１】
１５は巻き尺で、台部材１０の突出部１１寄りにケース１６が締結ねじ１７によって締結されて装着され、鋼製の計測テープ体１８が台部材１０の突出部１１の突出端面から下垂される。１９は巻き尺１５の計測テープ体１８の先端に連結された下げ振り形状の錘体である。
【００１２】
２０は制動手段で、台部材１０の突出部１１及び巻き尺１５のケース１６のいずれかに設けられて要時に人為操作によって巻き尺１５の計測テープ体１８を押圧して計測テープ体１８の上下移動を制動する。２１は位置決め片で、上端が台部材１０の突出部１１に枢着されて被測定物２の側面４に対面して配置され、また図１における時計方向の回動を阻止する阻止機構が設けられている。
【００１３】
２２は台部材１０に設けられた締結ねじ１７用の挿通孔で、巻き尺１５の台部材１０の長手に対する位置を移動させる場合に締結ねじ１７が挿通される。２３は測定器具であり、台部材１０、巻き尺１５、錘体１９、制動手段２０及び位置決め片２１を主要部材として構成される。２４は出入口開口部５の間口方向縁部におけるはつり削除箇所、２５は被測定物２の側面４におけるはつり削除箇所である。

【００１５】
上記のように構成されたエレベーター昇降路用測定器具において、エレベーター機器の据付作業の当初に次に述べるようにして昇降路１の測定作業が行われる。すなわち、一人の作業員によって作業が行われて、測定器具２３の台部材１０の主部材１２及び副部材１３が伸長され、また位置決め片２１が突起位置に配置される。
【００１６】
この状態で、最上階の乗場、すなわち被測定物２の上面３に測定器具２３の台部材１０が設置され、また位置決め片２１が被測定物２の昇降路１内側の側面４に接して配置されて図１に示す状態となる。そして、制動手段２０が人為操作されて巻き尺１５の計測テープ体１８の制動が解除され、計測テープ体１８が下方に延長され先端の錘体１９が最下階の乗場、すなわち最下階の被測定物２の上面３よりも下方に到達すると制動手段２０により巻き尺１５の計測テープ体１８が制動される。
【００１７】
これによって、図４及び図５に示す状態となり巻き尺１５の計測テープ体１８の下垂位置を基準として、距離Ａ、距離Ｂ、距離Ｃ、開口幅Ｄ、距離Ｅ、距離Ｆ、幅Ｇの測定を容易に行うことができる。なお、それぞれの乗場、すなわち被測定物２において距離Ａ、距離Ｂの値が許容値よりも小さい場合には、例えば出入口開口部５の間口方向縁部におけるはつり削除箇所２４、被測定物２の側面４におけるはつり削除箇所２５のはつり作業が行われる。
【００１８】
したがって、距離Ａの測定、すなわち出入口開口部５の昇降路１における間口方向位置の測定等の昇降路１の各部寸法の測定のために下げ振りを仮設する必要がなく、下げ振りの仮設に要する機材、工具を搬送する手数を解消することができる。このため、少ない作業員数による簡易な作業によって容易に昇降路１各部を測定でき、エレベーターの据付費を低減することができる。
【００１９】
また、測定器具２３の台部材１０が主部材１２及び主部材１２に枢着された副部材１３によって折り畳み可能に構成され、また位置決め片２１の一端が台部材１０に枢着されて折り畳み可能に構成される。これによって、不使用時に台部材１０等を図２に示すように折り畳んで測定器具２３の嵩を減らすことができるので、測定器具２３を携行する場合に便利である。また、昇降路１における作業勝手に対応して測定作業を容易化するために、締結ねじ１７用の挿通孔２２を利用して台部材１０に対する巻き尺１５の位置を台部材１０の長手に沿って変位することも可能である。
【００２０】
【発明の効果】
この発明は以上説明したように、長手の一端に被測定物である乗場の床面の側面から突出して配置される突出部が形成され、上記乗場の床面の上面に設置される台部材と、この台部材にケースが装着されて上記台部材の突出部の突出端から計測テープ体が下垂される巻き尺と、この巻き尺の計測テープ体の先端に連結された下げ振り形状の錘体と、上記台部材及び巻き尺のケースのいずれかに設けられて要時に人為操作によって上記巻き尺の計測テープ体を押圧して計測テープ体の上下移動を制動する制動手段と、上記台部材の突出部に一端が枢着されて上記乗場の床面の側面に対面して配置される折り畳み可能な位置決め片とを備え、上記台部材は、突出部側を形成した主部材、この主部材の反突出部側に配置された副部材及び上面に枢持軸が配置されて上記主部材に上記副部材を枢着した蝶番によって折り畳み可能に構成されて、測定作業時に展開伸長されるものであり、上記位置決め片は、測定作業時に折り畳み状態から展開されて阻止機構によって突起位置に保持されるものである。
【００２１】
これによって、エレベーター機器の据付作業の当初に作業員によって測定器具の主部材及び副部材からなる台部材が伸長されて最上階の乗場、すなわち被測定物の上面に設置され、また位置決め片が被測定物の昇降路内側の側面に接して配置される。そして、制動手段による巻き尺の計測テープ体の制動が解除されて下方に延長され、先端の錘体が最下階の乗場、すなわち被測定物の下方に吊設される。そして、計測テープ体の下垂位置を基準として、昇降路における水平方向の各部寸法が測定される。したがって、昇降路の各部寸法測定のために下げ振りを仮設する必要がなく、下げ振りの仮設に要する機材、工具を搬送する手数を解消することができる。このため、少ない作業員数による簡易な作業によって容易に昇降路各部を測定でき、エレベーターの据付費を低減する効果がある。また、測定器具の台部材が主部材及び主部材に枢着された副部材によって折り畳み可能に構成される。このため、台部材を折り畳んで不使用時の測定器具の嵩を減らすことができて測定器具の携行を容易化する効果がある。また、測定器具の位置決め片が折り畳み可能に構成される。このため、位置決め片を折り畳んで不使用時の測定器具の嵩を減らすことができて、測定器具の携行を容易化する効果がある。
