1 to 3 are diagrams showing an example of an embodiment of the present invention. FIG. 1 is a cross-sectional plan view of a hoistway, FIG. 2 is a side view on the arrow A side in FIG. 1, and FIG. FIG. In the figure, 1 is an elevator hoistway, 2 is a car rail standing upright from the hoistway 1, 3 is a car placed between the car rails 2, and 4 is away from the hoistway 1. This is a counterweight weight rail.

５は緩衝器台で、つり合おもり用レール４の相互間に配置されたつり合おもり（図示しない）に対応して昇降路１底面に設けられている。６は緩衝器台５から立設された二本の柱体からなる固定体で、上端側が取付金具７によって二本の柱体が相互に連結されると共に昇降路１壁に締結されている。   A shock absorber stand 5 is provided on the bottom surface of the hoistway 1 so as to correspond to a counterweight (not shown) disposed between the counterweight rails 4. Reference numeral 6 denotes a fixed body composed of two pillars erected from the shock absorber stand 5, and the upper end of the two pillars are connected to each other by the mounting bracket 7 and fastened to the wall of the hoistway 1.

８は固定体６の上端に締結されて連結された取付体で、鋼材がロ字状に組立てられた枠体によって構成され、上部及び下部の両端部にそれぞれ支持部９が設けられている。１０は巻上機で、ハウジングに収納されて側面を取付体８の前面に対面して配置された駆動綱車１１及びハウジングに設けられて取付体８の支持部９にそれぞれ対応すると共に支持部９の下側に配置された取付部１２が形成されている。   Reference numeral 8 denotes an attachment body fastened and connected to the upper end of the fixed body 6, which is constituted by a frame body in which steel materials are assembled in a square shape, and support portions 9 are provided at both upper and lower end portions. A hoisting machine 10 is housed in a housing and has a side surface facing the front surface of the attachment body 8 and a drive sheave 11 provided on the housing and corresponding to the support portion 9 of the attachment body 8 and a support portion. An attachment portion 12 is formed on the lower side of 9.

１３は取付体８の支持部９と巻上機１０の取付部１２の間にそれぞれ介装された防振ゴムからなる防振体、１４は駆動綱車１１に巻掛けられた主索で、図示が省略してあるが一端は昇降路１頂部に枢着された滑車に巻掛けられてかご３に連結され、他端は昇降路１頂部に枢着された他の滑車に巻掛けられてつり合おもりに連結されている。   13 is an anti-vibration body made of anti-vibration rubber interposed between the support portion 9 of the attachment body 8 and the attachment portion 12 of the hoisting machine 10, and 14 is a main rope wound around the drive sheave 11, Although not shown, one end is wound around a pulley pivotally attached to the top of the hoistway 1 and connected to the car 3, and the other end is wrapped around another pulley pivotally attached to the top of the hoistway 1. Connected to the counterweight.

上記のように構成されたエレベーター装置において、巻上機１０が水平投影面において昇降路１壁面とかご３の間に配置され、駆動綱車１１の側面が昇降路１壁面と対面して配置される。そして、巻上機１０の取付体８との対向面における四隅に設けられた取付部１２の上に配置された防振体１３によって、巻上機１０が取付体８を介して昇降路１に支持される。   In the elevator apparatus configured as described above, the hoisting machine 10 is arranged between the hoistway 1 wall surface and the car 3 on the horizontal projection plane, and the side surface of the driving sheave 11 is arranged facing the hoistway 1 wall surface. The And by the vibration isolator 13 arrange | positioned on the attachment part 12 provided in the four corners in the surface facing the attachment body 8 of the hoisting machine 10, the hoisting machine 10 goes to the hoistway 1 via the attachment body 8. Supported.

このような構成によって、巻上機１０が防振体１３によって昇降路１に防振支持され、巻上機１０に作用する上向き荷重によって防振体１３が圧縮されて防振作用が得られる。また、巻上機１０に作用するトルクが防振体１３の水平方向の剛性によって支持される。したがって、巻上機１０が取付体８に不具合なく支持されると共に、防振体１３による巻上機１０に関わる所要の防振作用が容易に得られる。これによって、昇降路１が設置された建物におけるエレベーター運転時の騒音、振動が少なくなり環境を静穏化することができる。   With such a configuration, the hoisting machine 10 is supported in the hoistway 1 by the vibration isolator 13 and the anti-vibration body 13 is compressed by the upward load acting on the hoisting machine 10 to obtain a vibration isolating action. Further, the torque acting on the hoisting machine 10 is supported by the horizontal rigidity of the vibration isolator 13. Therefore, the hoisting machine 10 is supported by the attachment body 8 without any trouble, and the necessary vibration isolating action related to the hoisting machine 10 by the vibration isolator 13 can be easily obtained. Thereby, the noise and vibration at the time of elevator operation in the building where the hoistway 1 is installed are reduced, and the environment can be calmed down.

また、図１〜図３の実施の形態において、巻上機１０のハウジングにおける上部及び下部の両端部にそれぞれに設けられた四個の防振体１３が配置される。このため、防振体１３を小形化することができ巻上機１０設置の所要スペースを少なくすることができる。したがって、昇降路１の形成に要するスペースが減少してエレベーター装置の設置費を節減することができる。   Moreover, in the embodiment of FIGS. 1 to 3, four vibration isolators 13 provided at both upper and lower ends of the housing of the hoisting machine 10 are arranged. For this reason, the vibration isolator 13 can be reduced in size and the required space for installing the hoisting machine 10 can be reduced. Therefore, the space required for forming the hoistway 1 can be reduced, and the installation cost of the elevator apparatus can be reduced.

また、図１〜図３の実施の形態において、取付体８がロ字状をなす枠体によって構成されて、防振体１３が取付体８の枠内の四隅に設けられる。このため、巻上機１０に作用する荷重を、最小の部材によって構成された取付体８によって支持できる。したがって、巻上機１０設置の所要スペースを少なくすることができ
、昇降路１の形成に要するスペースが減少してエレベーター装置の設置費を節減することができる。 In the embodiment shown in FIGS. 1 to 3, the attachment body 8 is constituted by a frame having a square shape, and the vibration isolator 13 is provided at four corners in the frame of the attachment body 8. For this reason, the load which acts on the hoisting machine 10 can be supported by the attachment body 8 comprised by the minimum member. Therefore, the space required for installing the hoisting machine 10 can be reduced, the space required for forming the hoistway 1 can be reduced, and the installation cost of the elevator apparatus can be reduced.

また、図１〜図３の実施の形態において、緩衝器台５から立設され固定体６に取付体８が装着される。また、上部によってつり合おもり側の滑車を支持したつり合おもり用レール４の下端に緩衝器台５が連結される。このため、巻上機１０に作用する上向き荷重が緩衝器台５に伝達されるものの、緩衝器台５から立設されたつり合おもり用レール４に設けられて、主索１４が巻掛けられたつり合おもり側の滑車を介してつり合おもり用レール４に作用する荷重によって、緩衝器台５における上向き荷重が相殺される。   In the embodiment shown in FIGS. 1 to 3, the attachment body 8 is mounted on the fixed body 6 standing from the shock absorber stand 5. The shock absorber stand 5 is connected to the lower end of the counterweight rail 4 that supports the counterweight-side pulley by the upper portion. For this reason, although the upward load acting on the hoisting machine 10 is transmitted to the shock absorber base 5, the main rope 14 is wound around the counterweight rail 4 erected from the shock absorber base 5. The upward load on the shock absorber base 5 is offset by the load acting on the counterweight rail 4 via the counterweight-side pulley.

したがって、取付体８を昇降路１壁に支持する特別な部材を要することなしに取付体８を設置することができる。これにより、取付体８を容易に昇降路１に設置することができ、取付体８の製作費及び据付費を低減することができる。   Therefore, the attachment body 8 can be installed without requiring a special member for supporting the attachment body 8 on the hoistway 1 wall. Thereby, the attachment body 8 can be easily installed in the hoistway 1, and the production cost and installation cost of the attachment body 8 can be reduced.

また、図１〜図３の実施の形態において、固定体６に取付金具７が設けられて固定体６が取付金具７を介して昇降路１壁に締結されている。このため、据付作業時に巻上機１０を揚重用のウインチとして使用してエレベーター装置の器材を揚重する場合には、取付金具７のみによって揚重負荷を支持することができる。したがって、据付作業の能率を向上し据付費を節減することができる。   In the embodiment shown in FIGS. 1 to 3, a mounting bracket 7 is provided on the fixed body 6, and the fixed body 6 is fastened to the wall of the hoistway 1 via the mounting bracket 7. For this reason, when the hoisting machine 10 is used as a lifting winch during the installation work to lift the equipment of the elevator apparatus, the lifting load can be supported only by the mounting bracket 7. Therefore, the efficiency of the installation work can be improved and the installation cost can be reduced.

また、図１〜図３の実施の形態において、固定体６に取付金具７が設けられて固定体６が取付金具７を介して昇降路１壁に締結されている。このため、二本の柱体からなる固定体６の横揺れを防止でき、固定体６の構成を簡易化でき製作費を低減することができる。   In the embodiment shown in FIGS. 1 to 3, a mounting bracket 7 is provided on the fixed body 6, and the fixed body 6 is fastened to the wall of the hoistway 1 via the mounting bracket 7. For this reason, it is possible to prevent the rolling of the fixed body 6 composed of the two pillars, simplify the configuration of the fixed body 6 and reduce the production cost.

また、図１〜図３の実施の形態において、緩衝器台５から立設された固定体６の上に取付体８が連結される。このような構成に対して、エレベーターの速度に対応して設定される昇降路１のピット深さの差異に対して、ピット深さに対応した高さに固定体６の高さ寸法を製作する。そして、予め準備された一定の取付体８と、ピット深さに対応した固定体６を組み合わせて巻上機１０を据付ける。これによって、製作費を低減することができる。   In the embodiment shown in FIGS. 1 to 3, the attachment body 8 is connected to the fixed body 6 erected from the shock absorber stand 5. For such a configuration, the height dimension of the fixed body 6 is manufactured at a height corresponding to the pit depth with respect to the difference in the pit depth of the hoistway 1 set corresponding to the speed of the elevator. . Then, the hoisting machine 10 is installed by combining the fixed body 8 prepared in advance and the fixed body 6 corresponding to the pit depth. As a result, the production cost can be reduced.
