BEST MODE FOR CARRYING OUT THE INVENTION
以下、 この発明の好適な実施の形態について図面を参照して説明する。  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.
実施の形態 1 . Embodiment 1
図 1はこの発明の実施の形態 1によるエレべ一夕装置を示す概略の構成図であ る。 図において、 昇降路 1内には、 一対のかごガイ ドレール （図示せず） と一対 の釣合おもりガイ ドレ一ル 2とが設置されている。 かご 3は、 かごガイ ドレール に案内されて昇降路 1内を昇降される。 釣合おもり 4は、 釣合おもりガイ ドレー ル 2に案内されて昇降路 1内を昇降される。  FIG. 1 is a schematic configuration diagram showing an elevator apparatus according to Embodiment 1 of the present invention. In the figure, a pair of car guide rails (not shown) and a pair of counterweight guide rails 2 are installed in a hoistway 1. The car 3 is guided up and down the hoistway 1 by the car guide rail. The counterweight 4 is guided by the counterweight guide rail 2 and moved up and down in the hoistway 1.
昇降路 1内の上部には、 かご 3及び釣合おもり 4を昇降させる駆動装置 （卷上 機） 5が配置されている。 駆動装置 5は、 モ一夕を含む駆動装置本体 6と、 駆動 装置本体 6により回転される駆動シ一ブ 7とを有している。  In the upper part of the hoistway 1, a driving device (winding machine) 5 for raising and lowering the car 3 and the counterweight 4 is arranged. The drive device 5 has a drive device main body 6 including a motor and a drive sheave 7 rotated by the drive device main body 6.
駆動シーブ 7には、 かご 3及び釣合おもり 4を吊り下げる複数本 （図では 1本 のみ示す） の主索 8が卷き掛けられている。 主索 8は、 かご側端部 8 a及び釣合 おもり側端部 8 bを有している。 かご側端部 8 aは、 かご側綱止め 9を介してか ご 3の上部に接続されている。  A plurality of (only one is shown in the figure) main ropes 8 suspending the car 3 and the counterweight 4 are wound around the drive sheave 7. The main rope 8 has a car side end 8a and a counterweight side end 8b. The car-side end 8a is connected to the top of the car 3 via a car-side cleat 9.
釣合おもりガイ ドレール 2の上端部には、 ロープ端支持梁 1 0が固定されてい る。 釣合おもり側端部 8 bは、 釣合おもり側綱止め 1 1を介してロープ端支持梁 A rope end support beam 10 is fixed to the upper end of the counterweight guide rail 2. The counterweight side end 8 b is connected to the rope end support beam via the counterweight side cleat 11.
1 0に接続されている。 釣合おもり 9の上部には、 主索 8が巻き掛けられた釣合 おもり吊り車 1 2が設けられている。 Connected to 10. At the top of the counterweight 9, the main rope 8 is wound around A weight lifting wheel 12 is provided.
かご 3は、 1 ： 1口一ビング方式により昇降路 1内に吊り下げられている。 ま た、 釣合おもり 4は、 2 ： 1口一ビング方式により昇降路 1内に吊り下げられて いる。 これにより、 釣合おもり 4の昇降行程は、 かご 3の昇降行程よりも短く (ほぼ半分） になっている。 即ち、 釣合おもり 4は、 昇降路 1の上下方向の中間 部よりも下側で昇降される。  The car 3 is suspended in the hoistway 1 by a one-by-one bing system. Further, the counterweight 4 is suspended in the hoistway 1 by a two-by-one bing method. As a result, the lifting stroke of the counterweight 4 is shorter (almost half) than that of the car 3. That is, the counterweight 4 is raised and lowered below the vertical middle part of the hoistway 1.
昇降路 1内の釣合おもり 4の上方には、 かご 3の昇降行程と釣合おもり 4の昇 降行程との差を利用して機器設置スペース 1 3が確保されている。 この機器設置 スペース 1 3には、 駆動装置 5の駆動を制御する機器である制御盤 1 4が配置さ れている。 また、 機器設置スペース 1 3には、 駆動装置 5の一部も配置されてい る。  Above the counterweight 4 in the hoistway 1, an equipment installation space 13 is secured by utilizing the difference between the lifting stroke of the car 3 and the lifting stroke of the counterweight 4. In the device installation space 13, a control panel 14 which is a device for controlling the driving of the driving device 5 is arranged. A part of the drive device 5 is also arranged in the equipment installation space 13.
このようなエレべ一夕装置では、 かご 3の昇降行程よりも釣合おもり 4の昇降 行程が短くなるように、 かご 3と釣合おもり 4とを互いに異なる口一ビング比で 吊り下げ、 昇降行程の差を利用して昇降路 1内に機器設置スペース 1 3を確保し たので、 昇降路 1内に広い機器設置スペース 1 3を確保することができる。 従つ て、 大型の駆動装置 5及び制御盤 1 4を配置したり、 複数の制御盤を配置したり することができ、 機械室レスエレべ一夕の適用範囲を広げることができる。  In such an elevator system, the car 3 and the counterweight 4 are suspended at different mouth-to-bing ratios so that the lifting and lowering steps of the counterweight 4 are shorter than the lifting and lowering steps of the car 3. A space 13 for installing equipment is secured in the hoistway 1 by utilizing the difference in travel distance, so that a large space 13 for installing equipment in the hoistway 1 can be secured. Therefore, a large-sized drive device 5 and a control panel 14 can be arranged, or a plurality of control panels can be arranged, and the applicable range of the machine room-less elevator can be widened.
また、 釣合おもり側端部 8 bがロープ端支持梁 1 0に接続されているので、 主 索 8が機器設置スペース 1 3を通過することがなく、 機器設置スペース 1 3に酉己 置される制御盤 1 4等の機器と主索 8とが干渉することがない。  Also, since the balance weight side end 8b is connected to the rope end support beam 10, the main cable 8 does not pass through the equipment installation space 13 and is located in the equipment installation space 13 by itself. There is no interference between devices such as the control panel 14 and the main cable 8.
なお、 上記の例では、 かご 3を 1 ： 1ロービング方式により吊り下げ、 釣合お もり 4を 2 ： 1ロービング方式により吊り下げたが、 かご 3の昇降行程よりも釣 合おもり 4の昇降行程が短くなればよく、 口一ビング比の組み合わせはこれに限 定されるものではない。 例えば、 かご 3側を 1 ： 1とし、 釣合おもり 4側を 4 ： 1としたり、 かご 3側を 2 ： 1とし、 釣合おもり 4側を 4 ： 1としたりしてもよ い o  In the above example, car 3 was hung by the 1: 1 roving method, and counterweight 4 was hung by the 2: 1 roving method. Should be as short as possible, and the combination of the mouth-to-bing ratio is not limited to this. For example, car 3 may be 1: 1 and counterweight 4 may be 4: 1, or car 3 may be 2: 1 and counterweight 4 may be 4: 1.
但し、 かご 3の昇降行程よりも釣合おもり 4の昇降行程を短くするためには、 かご 3側の口一ビング比を n ： 1、 釣合おもり 4側のロービング比を m： 1とし たとき、 n < m ( n、 mは自然数） とすればよい。 また、 上記のようなエレべ一夕装置では、 機械室レスエレべ一夕への適用が特 に有効であるが、 機械室を有するエレべ一夕装置にも適用でき、 広い機器設置ス ペースに種々の機器を配置することができる。 実施の形態 2 . However, in order to make the lifting / lowering stroke of the counterweight 4 shorter than that of the car 3, the mouth-to-buffing ratio of the car 3 was set to n: 1 and the roving ratio of the counterweight 4 was set to m: 1. In this case, n <m (where n and m are natural numbers) may be satisfied. In addition, in the above-described elevator system, the application to the machine room-less elevator system is particularly effective. Various devices can be arranged. Embodiment 2
図 2はこの発明の実施の形態 2によるエレべ一夕装置を示す正面図、 図 3は図 2のエレべ一夕装置を示す平面図である。 図において、 昇降路 1内の上部には、 一対の上部支持梁 1 5， 1 6が水平に固定されている。 駆動装置 5は、 かご 3の 真上で上部支持梁 1 5上に支持されている。 また、 駆動装置 5は、 駆動シーブ 7 の回転軸がかご 3の間口方向 （図 2、 3の左右方向） とほぼ平行に水平に延びる ように配置されている。  FIG. 2 is a front view showing an elevator apparatus according to Embodiment 2 of the present invention, and FIG. 3 is a plan view showing the elevator apparatus of FIG. In the figure, a pair of upper support beams 15 and 16 are fixed horizontally above the hoistway 1. The driving device 5 is supported on the upper support beam 15 directly above the car 3. In addition, the driving device 5 is arranged such that the rotation shaft of the driving sheave 7 extends horizontally substantially parallel to the frontage direction of the car 3 (the left-right direction in FIGS. 2 and 3).
上部支持梁 1 5 , 1 6には、 主索 8を駆動シーブ 7から釣合おもり吊り車 1 2 に導く回転自在のそらせ車 1 7が支持されている。 そらせ車 1 7は、 その回転軸 が駆動シ一ブ 7の回転軸と平行に延びるように配置されている。 また、 そらせ車 1 7は、 垂直投影面内でかご 3及び釣合おもり 4と重なるように配置されている c 昇降路 1内の釣合おもり 4の上方には、 かご 3の昇降行程と釣合おもり 4の昇 降行程との差を利用して機器設置スペース 1 3が確保されている。 この機器設置 スペース 1 3には、 駆動装置 5の駆動を制御する機器である第 1及び第 2の制御 盤 1 8， 1 9が配置されている。 第 1及び第 2の制御盤 1 8 , 1 9は、 かご 3の 間口方向に互いに間隔をおいて、 昇降路 1の壁部に固定されている。 他の構成は、 実施の形態 1と同様である。  A rotatable deflector 17 that guides the main rope 8 from the drive sheave 7 to the counterweight suspender 12 is supported by the upper support beams 15 and 16. The deflecting wheel 17 is arranged such that its rotation axis extends parallel to the rotation axis of the drive sheave 7. Also, the deflecting wheel 17 is arranged so as to overlap with the car 3 and the counterweight 4 in the vertical projection plane.c Above the counterweight 4 in the hoistway 1 The space for equipment installation 13 is secured by utilizing the difference between the lifting and lowering steps of the counterweight 4. In the device installation space 13, first and second control panels 18 and 19, which are devices for controlling the driving of the driving device 5, are arranged. The first and second control panels 18 and 19 are fixed to the wall of the hoistway 1 at intervals from each other in the direction of the frontage of the car 3. Other configurations are the same as those in the first embodiment.
