Description

【０００１】
【発明の属する技術分野】
本発明は、昇降路内に立設される一対のガイドレールを固定するエレベータのガイドレール固定装置に関する。
【０００２】
【従来の技術】
この種のエレベータのガイドレール固定装置は、ガイドレールが取付けられるレール側金具と、このレール側金具が移動可能に装着され、昇降路壁に固定される壁側金具とから主として構成されている。これらのレール側金具および壁側金具は、それぞれ水平片と垂直片とによってアングル形状（略Ｌ字状）に形成されており、それぞれの水平片には、昇降路内に立設した一対のガイドレールを結ぶ直線方向（レール方向）へ延びる縦長穴が設けられるとともに、壁側金具の垂直片には、ガイドレールの立設方向と直交する方向（奥行き方向）へ延びる横長穴が設けられている。
【０００３】
このような従来のガイドレール固定装置では、レール側金具の水平片と壁側金具の水平片を当接させた状態で、これらの水平片の縦長穴の相対位置が適切となるよう調整することにより、一対のガイドレールを結ぶ直線方向のガイドレール位置を調整する。また、壁側金具の垂直片に設けた横長穴のどの位置でこの垂直片を昇降路壁に固定するかにより奥行き方向のガイドレール位置を調整する。さらに、上記のように所定の位置にガイドレールを調整して固定した後、壁側金具を固定する固定具（アンカボルト）と壁側金具とを溶接し、この壁側金具とレール側金具とを溶接することにより位置ずれを防止するようになっている。しかしながら、この溶接作業は熟練を要するため未熟な作業者には非常に煩雑なものである。
【０００４】
そこで従来、例えば特開平４−１８２２８９号公報に記載されているように、壁側金具の固定具用穴を縦長穴と横長穴とすることにより位置ずれを防止し、固定具（アンカボルト）と壁側金具との溶接作業を不要としたガイドレール固定装置が提案されている。この従来のガイドレール固定装置では、壁側金具で奥行き方向の位置調整ができないため、レール側金具を奥行き方向とレール方向の両方に変位させることによりガイドレールの位置調整を行なうようになっている。
【０００５】
【発明が解決しようとする課題】
ところで、上記した従来技術では、壁側金具の縦長穴と横長穴とに固定具を通通して固定することにより壁側金具の位置ずれを防止できるが、昇降路内に立設した一対のガイドレールを結ぶ直線方向（レール方向）への調整代についての考慮が十分でなく、レール側金具の水平片に設けた縦長穴のみで、一対のガイドレールを結ぶ直線方向（レール方向）への調整代を確保するようになっているため、この直線方向へガイドレールを適切な位置に変位させて位置調整することができないという懸念がある。
【０００６】
本発明は、上述した従来技術における実情を鑑みてなされてなされたもので、その目的は、ガイドレールを固定する際に溶接作業を最小限に抑えるとともに、ガイドレールの位置調整代を十分に確保することのできるエレベータのガイドレール固定装置を提供することにある。
【０００７】
【課題を解決するための手段】
上記目的を達成するため本発明の請求項１に係る発明は，エレベータの昇降路内に立設される一対のガイドレールをそれぞれ固定するエレベータのガイドレール固定装置において、前記昇降路の内壁に固定される垂直片、およびこの垂直片と一体に形成される水平片からなるアングル形状の壁側金具と、この壁側金具の水平片に対して移動可能に固定される水平片、およびこの水平片と一体に形成され、前記ガイドレールが取付けられる垂直片からなるアングル形状のレール側金具と、これらの壁側金具およびレール側金具を互いに締結する複数個の締結具と備えるとともに、前記壁側金具の水平片に、前記一対のガイドレールを結ぶ直線方向へ延び、第１の締結具が挿通される第１の縦長穴と、前記直線方向に直交する方向へ延び、かつ前記第１の縦長穴をそれぞれ通る直線上に位置し、第２の締結具が挿通可能な少なくとも２つの第１の横長穴とを設け、前記壁側金具の垂直片に、この壁側金具を前記昇降路の内壁に固定する固定具の外径と略同一の穴幅を有する固定具用穴を設け、前記レール側金具の水平片に、前記に延び、前記第２の締結具が挿通される第２の縦長穴と、前記直線方向に直交する方向へ延び、かつ前記第２の縦長穴をそれぞれ通る直線上に位置し、前記第１の締結具が挿通可能な少なくとも２つの第２の横長穴とを設けた構成にしてある。
【０００８】
このように構成した本発明の請求項１に係る発明では、壁側金具の水平片に設けた第１の縦長穴とレール側金具の水平片に設けた第２の横長穴とを適切な位置に調整するとともに、壁側金具の水平片に設けた第１の横長穴とレール側金具の水平片に設けた第２の縦長穴とを適切な位置に調整することにより、レール側金具の位置を一対のガイドレールを結ぶ直線方向およびこの直線方向に直交する方向に調整する。その際に、壁側金具の水平片に設けた第１の縦長穴およびレール側金具の水平片に設けた第２の縦長穴に沿ってレール側金具を一対のガイドレールを結ぶ直線方向へ移動させるとともに、壁側金具の水平片に設けた少なくとも２つの第１の横長穴のいずれかを選択して第２の締結具を挿通し、レール側金具の水平片に設けた少なくとも２つの第２の横長穴のいずれかを選択して第１の締結具を挿通する。これにより、一対のガイドレールを結ぶ直線方向へガイドレールを大きく変位させて位置調整を行なえるので、ガイドレールの位置調整代を十分に確保することができる。また、壁側金具の垂直片に設けた固定具用穴に固定具を挿通して昇降路の内壁に固定することにより、固定具用穴の穴幅が固定具の外径と略同一であるので壁側金具の位置ずれを防止できる。これによって、ガイドレールを固定する際に、壁側金具および固定具用の溶接を省略して溶接作業を最小限に抑えることができる。
【０００９】
また、本発明の請求項２に係る発明は、請求項１に係る発明において、請求項１の記載において、前記壁側金具の垂直片および水平片を略同一形状で構成するとともに、前記壁側金具の垂直片に、前記ガイドレールの立設方向へ延びる第３の縦長穴と、前記立設方向に直交する方向へ延び、かつ前記第３の縦長穴をそれぞれ通る直線上に位置する少なくとも２つの第３の横長穴とを設け、前記壁側金具の水平片および垂直片を反転した状態で前記水平片を前記昇降路の内壁に取付けたとき、水平方向に配置した前記垂直片の第３の縦長穴に前記第１の締結具を挿通し、かつ前記第３の横長穴に前記第２の締結具を挿通可能とした構成にしてある。
【００１０】
このように構成した本発明の請求項２に係る発明では、壁側金具の水平片および垂直片を反転し、水平片を昇降路の内壁に取付けるとともに垂直片を水平方向に配置した場合、この垂直片に設けた第３の横長穴と、レール側金具の水平片に設けた第２の縦長穴とに第２の締結具を挿通し、前記の水平方向に配置した垂直片に設けた第３の縦長穴と、レール側金具の水平片に設けた第２の横長穴とに第１の締結具を挿通することにより壁側金具とレール側金具を互いに締結する。これによって、壁側金具の水平片と垂直片を反転した状態でも使用可能なので、作業者が壁側金具の取付状態を判断する作業が１つ減り、ガイドレールを固定する際の作業効率を向上できる。
【００１１】
【発明の実施の形態】
以下，本発明のエレベータのガイドレール固定装置の実施の形態を図に基づいて説明する。
【００１２】
図１は本発明の一実施形態に係るエレベータのガイドレール固定装置を示す平面図，図２は本実施形態に設けられるレール側金具を昇降路壁の近傍まで移動させた状態を示す平面図，図３は本実施形態の正面図，図４は本実施形態に設けられる壁側金具を示す斜視図、図５は本実施形態に設けられるレール側金具を示す斜視図である。
【００１３】
図１〜図３に示すエレベータでは、昇降路１内に、図示しない乗かごやつり合いおもりなどの昇降体の昇降をガイドする一対のガイドレール２が立設され、昇降路壁（すなわち昇降路１の内壁）３に固定されている。また、図示していないが昇降路壁３に対向する部位に位置する他の昇降路壁にも、別のガイドレール２が固定されている。図１〜図５に示すＸ方向はこれら一対のガイドレール２を結ぶ直線方向（レール方向）であり、Ｙ方向は一対のガイドレール２を結ぶ直線方向と直交する方向（奥行き方向）であり、Ｚ方向はガイドレール２の立設方向である。
【００１４】
そして、本実施形態のガイドレール固定装置４は、それぞれアングル形状（略Ｌ字状）に形成される壁側金具５およびレール側金具６と、これらの壁側金具５およびレール側金具６を互いに締結する一対の締結具７ａ、７ｂと、壁側金具５を昇降路壁３に固定する固定具、例えばアンカボルト８と、レール側金具６に装着され、ガイドレール２を把持するレールクリップ９とから構成されている。
【００１５】
壁側金具５は、昇降路壁３に固定される垂直片１０と、この垂直片１０と一体に形成される水平片１１とからなり、これらの垂直片１０および水平片１１は略同一形状で構成されている。同様に、レール側金具６は、壁側金具５の水平片１１に対して水平方向へ移動可能に固定される他の水平片１２と、この水平片１２と一体に形成される垂直片１３とからなり、これらの水平片１２および垂直片１３も略同一形状で構成されている。
【００１６】
壁側金具５の水平片１１には、図４に示すように、一対のガイドレール２を結ぶ直線方向（すなわちＸ方向）に延びる第１の縦長穴１４と、一対のガイドレール２を結ぶ直線方向と直交する方向（すなわちＹ方向）に延び、かつ第１の縦長穴１４の両端部を通る直線上にそれぞれ位置する２つの第１の横長穴１５、１６とが設けられている。これらの第１の縦長穴１４、および第１の横長穴１５、１６のそれぞれの短手方向の穴幅は、締結具７の外径と略同一となるように設定されている。また、第１の縦長穴１４の長手方向の長さＬ１と、第１の横長穴１５の短手方向の外端および第１の横長穴１６の短手方向の外端間の寸法Ｌ２とが同一に設定されている。
【００１７】
壁側金具５の垂直片１０には、ガイドレール２の立設方向（Ｚ方向）へ延びる第３の縦長穴１９と、前記の立設方向に直交する方向（Ｙ方向）へ延び、かつ第３の縦長穴１９の両端部をそれぞれ通る直線上に位置する２つの第３の横長穴１７，１８とが設けられている。これらの第３の縦長穴１９および第３の横長穴１７、１８の短手方向の穴幅は、それぞれアンカボルト８の外径と略同一に設定されており、これらの第３の縦長穴１９、および第３の横長穴１７、１８によってアンカボルト８が挿通される固定具用穴が構成されている。また、壁側金具５の垂直片１０および水平片１１を図４に示す状態から反転し水平片１１を昇降路壁３に取付けたとき、水平方向に配置した垂直片１０の第３の縦長穴１９に第１の締結具７ａが挿通されるとともに、第３の横長穴１７，１８に第２の締結具７ｂが挿通可能である。
【００１８】
レール側金具６の水平片１２には、図５に示すように一対のガイドレール２を結ぶ直線方向（Ｘ方向）に延び、第２の締結具７ｂが挿通される第２の縦長穴２２と、前記の直線方向に直交する方向（Ｙ方向）に延び、かつ第２の縦長穴２２の両端部をそれぞれ通る直線上に位置し、第１の締結具７ａが挿通可能な２つの第２の横長穴２０，２１と、レールクリップ９が挿通可能な貫通穴２３、２４とが設けられている
レール側金具６の垂直片１３には、図５に示すようにガイドレール２の立設方向（Ｚ方向）へ延びる第４の縦長穴２７と、前記の立設方向に直交する方向（Ｙ方向）へ延び、かつ第４の縦長穴２７の両端部をそれぞれ通る直線上に位置する２つの第４の横長穴２５，２６と、レールクリップ９が挿通される貫通穴２８、２９とが設けられている。また、レール側金具６の水平片１２および垂直片１３を図５に示す状態から反転して水平片１２を昇降路壁３に取付けたとき、水平方向に配置した垂直片１３の第４の縦長穴２７に、第２の締結具７ｂが挿通されるとともに、第４の横長穴２５，２６に第１の締結具７ａが挿通可能である。
【００１９】
この実施形態のガイドレール固定装置４では、壁側金具５およびレール側金具６を用いてガイドレール２を固定する際に、まず壁側金具５の垂直片１０の第３の縦長穴１９と、第３の横長穴１７、１８のいずれかとにアンカボルト８を打込み、壁側金具５を昇降路壁３に固定する。このようにして壁側金具５を固定したなら、次に、レール側金具６にレールクリップ９にてガイドレール２を把持した後、レール側金具６を壁側金具５に対してＸ方向およびＹ方向に位置調整して適切な位置にガイドレール２を取付ける。その際、例えば図１に示すように、壁側金具５の第１の縦長穴１４とレール側金具６の第２の横長穴２０とに第１の締結具７ａを挿通し、レール側金具６の第２の縦長穴２２と壁側金具５の第１の横長穴１５とに第２の締結具７ｂを挿通して、レール側金具６をＸ方向へ移動させた状態（すなわち図１に示す状態）で壁側金具５およびレール側金具６を互いに締結することにより、昇降路壁３からＸ方向へ離れた位置にガイドレール２を固定することができる。
【００２０】
また、図２に示すように、壁側金具５の第１の縦長穴１４とレール側金具６の第２の横長穴２１とに第１の締結具７ａを挿通し、レール側金具６の第２の縦長穴２２と壁側金具５の第１の横長穴１６とに第２の締結具７ｂを挿通して、レール側金具６をＸ方向と逆方向へ移動させた状態（すなわち図２に示す状態）で壁側金具５およびレール側金具６を互いに締結することにより、昇降路壁３に比較的近い位置にガイドレール２を固定することができる。
【００２１】
このようにして壁側金具５に対するレール側金具６の位置調整を行なった後、壁側金具５とレール側金具６とを溶接固定して位置ずれ防止を図り、ガイドレール２の固定作業を完了する。
【００２２】
このように構成した本実施形態では、壁側金具５の水平片１１に設けた第１の縦長穴１４およびレール側金具６の水平片１２に設けた第２の縦長穴２２に沿ってレール側金具６をＸ方向へ移動させるとともに、壁側金具５の水平片１１に設けた２つの第１の横長穴１５、１６のいずれかを選択して第２の締結具７ｂを挿通し、レール側金具６の水平片１２に設けた２つの第２の横長穴２０、２１のいずれかを選択して第１の締結具７ａを挿通することにより、一対のガイドレール２を結ぶ直線方向（Ｘ方向）へガイドレール２を大きく変位させて位置調整を行なえるので、ガイドレール２の位置調整代を十分に確保することができる。
【００２３】
また、本実施形態では、壁側金具５の垂直片１０に設けた第３の縦長穴１９および第３の横長穴１７，１８にアンカボルト８を挿通して昇降路壁３に固定したとき、第３の縦長穴１９の短手方向の内径がアンカボルト８の外径と略同一であるので壁側金具５のＹ方向への位置ずれを防止でき、第３の横長穴１７，１８の短手方向の内径がアンカボルト８の外径と略同一であるので壁側金具５のＺ方向への位置ずれを防止できることから、壁側金具５およびアンカボルト８の溶接作業を省略してガイドレール２を固定する際に溶接作業を最小限に抑えることができる。
【００２４】
また、本実施形態では、壁側金具５の垂直片１０と水平片１１を反転した状態でも使用可能なので作業者が壁側金具５の取付状態を判断する作業が１つ減り、ガイドレール２を固定する際の作業効率を向上できる。同様に、レール側金具６の垂直片１３と水平片１２を反転した状態でも使用可能なので、この点でもガイドレール２を固定する際の作業効率を向上できる。
【００２５】
なお、上記実施形態では、壁側金具５の水平片１１に設けた第１の縦長穴１４の長さと、垂直片１０に設けた第３の縦長穴１９の長さとを異なるように設定したので、Ｘ方向の位置調整幅を広げることが可能である。さらに、第１の縦長穴１４の長さと第３の縦長穴１９の長さとを同一に設定することもできる。また、レール側金具６の水平片１２に設けた第２の縦長穴２２の長さと垂直片１３に設けた第４の縦長穴２７の長さとに関しても同様である。
【００２６】
さらに、上記実施形態にあっては、壁側金具５の水平片１１の第１の横長穴１５，１６を第１の縦長穴１４の両端部をそれぞれ通る直線上に設けたが、第１の縦長穴１４の長手方向の範囲内であれば、第１の横長穴をいくつ設けても同様の効果が有ることは言うまでもない。
【００２７】
さらに、上記実施形態にあっては、図１，図２に示すように第１の横長穴１５、１６、および第２の横長穴２０、２１との中央部に締結具７を取付ける場合を例示したが、この締結具７の位置を奥行き方向（Ｙ方向）にずらすことにより奥行き方向の位置調整を行なうことが可能である。
【００２８】
【発明の効果】
以上説明したように本発明によれば、ガイドレールを昇降路壁に固定する際に溶接作業を最小限に抑えられるとともに、ガイドレールの位置調整代を十分に確保することができる。したがって、ガイドレール固定時の作業効率を向上できるとともに、エレベータ据付現場に応じて大きな調整代が要求される場合にも適切な位置にガイドレールを固定することができ、多くの現場にて適用可能なエレベータのガイドレール固定装置を提供できるという効果がある。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a guide rail fixing device for an elevator for fixing a pair of guide rails erected in a hoistway.
[0002]
[Prior art]
An elevator guide rail fixing device of this type mainly includes a rail-side bracket to which a guide rail is attached, and a wall-side bracket to which the rail-side bracket is movably mounted and fixed to a hoistway wall. Each of the rail-side metal fittings and the wall-side metal fittings is formed in an angle shape (substantially L-shape) by a horizontal piece and a vertical piece, and each of the horizontal pieces has a pair of guides standing upright in a hoistway. A vertically long hole extending in a linear direction (rail direction) connecting the rails is provided, and a horizontally long hole extending in a direction (depth direction) orthogonal to the standing direction of the guide rail is provided in a vertical piece of the wall-side bracket. .
[0003]
In such a conventional guide rail fixing device, in a state where the horizontal piece of the rail-side bracket and the horizontal piece of the wall-side bracket are in contact with each other, it is necessary to adjust the relative positions of the vertically long holes of these horizontal pieces to be appropriate. Thereby, the position of the guide rail in the linear direction connecting the pair of guide rails is adjusted. Further, the position of the guide rail in the depth direction is adjusted according to the position of the horizontally long hole provided in the vertical piece of the wall-side bracket at which the vertical piece is fixed to the hoistway wall. Further, after the guide rail is adjusted and fixed at a predetermined position as described above, a fixture (anchor bolt) for fixing the wall-side bracket is welded to the wall-side bracket, and the wall-side bracket and the rail-side bracket are welded. Is welded to prevent displacement. However, since this welding operation requires skill, it is very complicated for an unskilled worker.
[0004]
Therefore, conventionally, as described in, for example, Japanese Patent Application Laid-Open No. 4-182289, a hole for a fixture of a wall-side bracket is formed into a vertically long hole and a horizontally long hole to prevent displacement, and a fixing device (anchor bolt) is used. A guide rail fixing device that does not require welding work with a wall side fitting has been proposed. In this conventional guide rail fixing device, the position adjustment of the guide rail is performed by displacing the rail-side bracket in both the depth direction and the rail direction because the wall-side bracket cannot adjust the position in the depth direction. .
[0005]
[Problems to be solved by the invention]
By the way, in the above-mentioned prior art, the positional displacement of the wall-side bracket can be prevented by passing the fixture through the vertically long hole and the horizontally long hole of the wall-side bracket, but a pair of guides provided upright in the hoistway Adjustment in the linear direction (rail direction) connecting the pair of guide rails is not enough due to the consideration of the adjustment allowance in the linear direction (rail direction) connecting the rails, and only the vertically long hole provided in the horizontal piece of the rail side bracket. Since a margin is secured, there is a concern that the position cannot be adjusted by displacing the guide rail to an appropriate position in this linear direction.
[0006]
The present invention has been made in view of the above-mentioned circumstances in the prior art, and its purpose is to minimize welding work when fixing the guide rail, and to sufficiently secure a position adjustment allowance for the guide rail. It is an object of the present invention to provide an elevator guide rail fixing device capable of performing the following.
