Description

明 細 書  Specification
エレべ一夕用ドア装置 技術分野 Technical field of door device for elevator
本発明は、 エレべ一夕用ドア装置に関する。 背景技術  The present invention relates to a door device for an elevator. Background art
一般の建物の出入口に設けてある自動ドアにおいては、 2枚中央開き戸の場 合、 駆動するドアは通常 2枚であり、 質量は 5 0 ~ 7 0 k g程度であることが 多い。 一方、 エレべ一夕用ドア装置では同じ 2枚中央開き戸でも、 かご側ドア と乗場側ドアの両方を動かす必要があり、 また設備上、 自動ドアよりも高い安 全性が求められるため、 駆動するドア質量が自動ドアの 2倍以上の 1 0 0〜 4 0 0 k g程度となる。また、屋外と建物の間に設置される自動ドアに比べて、 建屋の中に設置されるエレべ一夕用ドアは高い静粛性を要求されるため、 自動 ドアで一般的に使用されるギヤ付モ一夕よりも、 騒音が低いギヤレスモー夕が 望ましく、 そのため、 モー夕が必要とするトルクが大きくなり、 自動ドアと比 較して体格が大きい。  In the case of automatic doors installed at entrances and exits of general buildings, if two central doors are used, usually two doors are driven, and the mass is often about 50 to 70 kg. On the other hand, with the door device for the elevator, it is necessary to move both the car-side door and the landing-side door even with the same two-fold central door, and the equipment requires higher safety than the automatic door, so the drive The weight of the door is 100 to 400 kg, which is more than twice that of an automatic door. In addition, compared to automatic doors installed between the outside and the building, doors for elevators installed inside buildings require higher quietness, so gears commonly used for automatic doors are used. It is desirable to use a gearless motor with lower noise than with a motor, so the torque required by the motor is larger and the physical size is larger than that of an automatic door.
また、 自動ドアは上下方向に対しては、 天井高さ以下に納める必要があるた め、寸法の制約が厳しいが、 ドアの表面に沿う平面に対して直交する方向には、 障害物があることは少なく、 寸法の制約は緩い。  In addition, automatic doors must be kept below the ceiling height in the vertical direction, so dimensional restrictions are severe, but there are obstacles in the direction perpendicular to the plane along the door surface. And the dimensional constraints are loose.
以上述べたように、 自動ドアでは一般的にエレべ一夕用ドア装置に比べて、 モ一夕の体格が小さく、 さらにドアの表面に沿う平面に対して直交する方向へ の寸法の制約が緩いことから、 モ一夕がドアの表面に沿う平面に対してほぼ直 交する方向に配置される回転軸を有すると共に、 この回転軸の長さを自動装置 の幅より短く設定することは容易であり、 一般的に行われている。  As described above, in general, automatic doors are smaller in size than elevator door devices, and the size of the door is limited in the direction perpendicular to the plane along the door surface. Because of its looseness, it is easy to have a rotating shaft that is arranged in a direction substantially perpendicular to the plane along the surface of the door, and to set the length of this rotating shaft shorter than the width of the automatic device. It is generally done.
一方、エレべ一夕用ドアは前述したような理由から、モー夕の体格が大きく、 さらに、 エレべ一夕用ドア装置は、 一般的にかご上に設けられているため、 ド ァの表面に沿う平面に対して、 ほぼ直交する方向に乗場側ドア装置の部品があ り、 エレべ一夕走行中に、 これらの部品に接触しないよう、 ドアの表面に沿う 平面に対して、 ほぼ直交する方向に対しての寸法制約が厳しい （2枚戸中央開 き戸では約 9 0 mm)。 これに対して、 エレべ一夕ではかご天井よりも高い位 置に装置を配置していることが多いため、 自動ドアに比べて上下方向の寸法の 制約は緩く、 出入口高さより 3 0 0 mm以上ゆるされていることが多い。 以上述べたようなエレべ一夕用ドア装置のモ一夕の特徴、 および設置条件の 特徴から、 エレべ一夕用ドア装置において、 モー夕をかご側シルの乗場側端部 からレール枠のかご側端部までの間に設置する場合、 回転軸をほぼ鉛直に配置 するようにしていた。 On the other hand, the door for the Elebe night has a large physique for the reason mentioned above, Furthermore, since the elevator door device is generally provided on a car, there are parts of the landing-side door device in a direction substantially orthogonal to a plane along the surface of the door. Strict dimensional restrictions are applied in the direction almost perpendicular to the plane along the door surface so that they do not come into contact with these parts during overnight driving. ). On the other hand, in the case of the elevator, the equipment is often placed at a higher position than the car ceiling, so the restrictions on the vertical dimensions are less strict than the automatic door, and it is 300 mm higher than the entrance height. In many cases, they have been loosened. Based on the characteristics of the mower and the installation conditions of the door device for the elevator and elevator as described above, the door device for the elevator and the elevator were moved from the end of the car side sill to the rail frame. When installed between the car side end, the rotating shaft was arranged almost vertically.
回転軸を鉛直に配置している従来のエレべ一夕用ドア装置としては、 特開平 8 - 2 0 8 1 5 9号公報に記載のものが知られており、 これを図 7に示してい る。  As a conventional elevator door device in which the rotating shaft is arranged vertically, the one described in Japanese Patent Application Laid-Open No. Hei 8-20859 is known, and this is shown in FIG. You.
エレべ一夕のかごドア 1 2 , 1 3は、 その上部に可回転的なローラ 8〜 1 1 を有するハンガ 6 , 7をそれそれ取り付け、 各ハンガ 6 , 7の可回転的な口一 ラ 8〜1 1がレール枠 5に固定したドアレール 1 4に沿って水平方向に走行可 能にすると共に、 かごドア 1 2， 1 3の下部にドアシュ一 1 5〜1 8を取り付 け、 このドアシュ一 1 5〜1 8がシル 1 9に沿って水平方向に移動可能に構成 している。 レール枠 5の左端部には、 その回転軸に駆動プーリ 2を取り付けた ドアモー夕 1が配置され、 またレール枠 5の右端部には、 この駆動プーリ 2と 対向して従動プーリ 3が配置されている。 駆動プーリ 2と従動プーリ 3間には ドアモータ 1の回転を直線運動に変換するドアベルト 4が巻き付けられ、 この ドアベルト 4とハンガ 6， 7間はブラケット 2 0 , 2 1によってそれそれ連結 されている。従って、 ドアモ一夕 1の回転は駆動プーリ 2と従動プーリ 3間で のドアベルト 4の水平面上での回動に変換され、 このドアペルト 4にブラケヅ ト 2 0 , 2 1によって連結されたかご側ドア 1 2， 1 3を開閉することになる。 ここでドアモー夕 1は、 その回転軸の軸方向に長くかつ径を小さくして製作さ れ、 その回転軸をほぼ鉛直に配置するようにしていた。 The elevator doors 1 2, 1 3 of the elevator are equipped with hangers 6, 7 each having a rotatable roller 8-11 on top thereof, and the rotatable doors of each hanger 6, 7. 8 to 11 can run horizontally along the door rail 14 fixed to the rail frame 5, and door doors 15 to 18 are attached to the lower parts of the car doors 12 and 13. The doors 15 to 18 are configured to be movable in the horizontal direction along the sill 19. At the left end of the rail frame 5, a door motor 1 having a drive pulley 2 attached to its rotating shaft is arranged, and at the right end of the rail frame 5, a driven pulley 3 is arranged facing the drive pulley 2. ing. A door belt 4 for converting the rotation of the door motor 1 into a linear motion is wound between the driving pulley 2 and the driven pulley 3, and the door belt 4 and the hangers 6, 7 are connected to each other by brackets 20, 21 respectively. Therefore, the rotation of the door belt 1 is converted into the rotation of the door belt 4 between the driving pulley 2 and the driven pulley 3 on the horizontal plane. The car side doors 12 and 13 connected by the ports 20 and 21 open and close. Here, door motor 1 was manufactured so as to be long and small in the axial direction of the rotation axis, and the rotation axis was arranged almost vertically.
しかしながら、 従来のエレべ一夕用ドア装置では、 かごドア 1 2 , 1 3から の出入り方向におけるレール枠 5の幅内にドアモー夕 1を配置しなければなら ないので、 ドアモ一夕 1の回転軸に取り付けた駆動プーリ 2の径をレール枠 5 の幅内に収まるように設計すると駆動プ一リ 2の径が制限されることになり、 駆動プーリ 2の部分で小さな曲率半径で回動するよう大きく変化するドアベル ト 4の寿命を低下させたり、 駆動できるかごドア 1 2， 1 3の質量が制限され てしまう。 またエレべ一夕用ドア装置に減速装置を取り付ける場合も、 その減 速プーリをレール枠 5の幅内に収めようとすると減速比を大きくすることがで きず、モ一夕トルクとの関係でかごドア 1 2 , 1 3の質量が制限されてしまう。 従って、 ホテルなどにおいて、 かごドア 1 2， 1 3の高さを増したり、 その表 裏面に化粧板を貼り付けて美観性や意匠性を向上させたいとの要望があるが、 これを実施することができなかった。  However, in the conventional elevator door device, the door motor 1 must be arranged within the width of the rail frame 5 in the direction of the entrance and exit from the car doors 12 and 13, so that the door motor 1 rotates. If the diameter of the drive pulley 2 attached to the shaft is designed to be within the width of the rail frame 5, the diameter of the drive pulley 2 will be limited, and the drive pulley 2 will rotate with a small radius of curvature. The life of the door belt 4, which varies greatly, is reduced, and the weight of the car doors 12, 13 that can be driven is limited. Also, when a speed reducer is installed in the door device for the elevator, the reduction ratio cannot be increased if the speed reduction pulley is set within the width of the rail frame 5, and the speed reduction ratio cannot be increased. The weight of the car doors 12 and 13 is limited. Therefore, in hotels, etc., there is a demand to increase the height of the car doors 12 and 13 or to attach decorative panels on the front and back sides to improve the aesthetics and design, but this will be implemented. I couldn't do that.

本発明は上述の目的を達成するために、 かごドアと、 このかごドアの上部を ガイドするドアレールと、 このドアレールを保持しかごに固定されるレール枠 と、 前記かごドアの下部をガイドするシルと、 このシルの乗場側端部から前記 レール枠のかご側端部までの領域に配置されて前記かごドアを駆動するドアモ —夕と、 このドアモー夕の回転軸に設けられる駆動プーリと、 この駆動プーリ と対向して設けられる従動プーリと、 これらの駆動プーリと従動プーリに卷き 付けられ、 前記かごドァが取り付けられるドアベルトとを有するエレべ一夕の ドア装置において、 前記ドアモータが、 前記かごドアの表面に沿う平面に対し てほぼ直交する方向に配置される回転軸を有すると共に、 この回転軸の長さを 前記シルの乗場側端部から前記レール枠のかご側端部までの距離よりも短く設 定したことを特徴とする。 In order to achieve the above object, the present invention provides a car door, a door rail for guiding an upper part of the car door, a rail frame for fixing the door rail to a car, and a sill for guiding a lower part of the car door. A door motor which is disposed in a region from the landing side end of the sill to the car side end of the rail frame and drives the car door; A driven pulley provided opposite to the driving pulley, and winding the driven pulley and the driven pulley And a door belt to which the car door is attached. In addition, the length of the rotating shaft is set to be shorter than the distance from the landing end of the sill to the car end of the rail frame.
本発明によるエレべ一夕用ドア装置は、 ドアモー夕が、 かごドアの表面に沿 う平面に対してほぼ直交する方向に配置される回転軸を有すると共に、 この回 転軸の長さをシルの乗場側端部からレール枠のかご側端部までの距離よりも短 く設定したため、 レール枠の幅を増すことなく、 ドアベルトの曲率半径を比較 的大きくすることができるので 4の寿命を向上させると共に、 かごドアの質量 増大に対処することができる。  The door device for an elevator according to the present invention is characterized in that the door motor has a rotating shaft arranged in a direction substantially orthogonal to a plane along the surface of the car door, and the length of the rotating shaft is set to a length.

Since the torque of the motor generally depends on the surface area of the magnet, it is possible to increase the torque more efficiently in the radial direction than in the axial direction. It can be raised efficiently. At this time, from the torque required for the motor of the door device for the elevator, the diameter of the motor is about two to three times the length of the motor in the axial direction if two centrally located doors are taken as an example. , 200 to 300 mm.

以下、 本発明の実施の形態を図面に基づいて説明する。  Hereinafter, embodiments of the present invention will be described with reference to the drawings.
図 1は、 本発明の一実施の形態によるエレべ一夕用ドア装置を示す正面図で ある。  FIG. 1 is a front view showing an elevator door apparatus according to an embodiment of the present invention.
エレべ一夕のかごドア 1 2， 1 3は、 その上部に可回転的なローラ 8〜1 1 を有するハンガ 6 , 7をそれそれ取り付け、 各ハンガ 6， 7の可回転的なロー ラ 8〜； L 1がレール枠 5に固定したドアレール 1 4に沿って水平方向に走行可 能にすると共に、 かごドア 1 2 , 1 3の下部にドアシュ一 1 5〜1 8を取り付 け、 このドアシュ一 1 5〜1 8がシル 1 9に沿って水平方向に移動可能に構成 している。 レール枠 5の左端部には、 その回転軸に駆動プーリ 2を取り付けた ドアモ一夕 1が配置され、 またレール枠 5の右端部には、 この駆動プーリ 2と 対向して従動プーリ 3が配置されている。 駆動プーリ 2と従動プーリ 3間には ドアモー夕 1の回転をほぼ直線運動に変換するドアベルト 4が巻き付けられ、 このドアベルト 4とハンガ 6 , 7間はブラケヅト 2 0， 2 1によってそれそれ 連結されている。 シル 1 9およびかご枠 5などは、 エレべ一夕のかご 2 2を支 えるかご枠 2 3に固定されている。  The elevator doors 12 and 13 of the elevator are equipped with hangers 6 and 7 having rotatable rollers 8 to 11 on top thereof, respectively, and the rotatable rollers 8 of each hanger 6 and 7 are attached. L1 can run horizontally along the door rail 14 fixed to the rail frame 5, and door doors 15 to 18 are attached to the lower parts of the car doors 12 and 13. The doors 15 to 18 are configured to be movable in the horizontal direction along the sill 19. At the left end of the rail frame 5, a door frame 1 having a driving pulley 2 attached to its rotating shaft is arranged, and at the right end of the rail frame 5, a driven pulley 3 is arranged opposite to the driving pulley 2. Have been. A door belt 4 for converting the rotation of the door motor 1 into a substantially linear motion is wound between the driving pulley 2 and the driven pulley 3, and the door belt 4 and the hangers 6, 7 are connected to each other by brackets 20, 21, respectively. I have. The sill 19 and the car frame 5 are fixed to the car frame 23 that supports the elevator car 22.
図 2は、 図 1に示したエレべ一夕用ドァ装置を右方から見た側面図である。 エレべ一夕用ドア装置は、 シル 1 9の乗場側端部からレール枠 5のかご側端 部までの距離 W内に構成しており、 特に、 ドアモ一夕 1は、 かごドア 1 2， 1 3の表面に沿う平面に対してほぼ直交する方向に配置される回転軸を有する と共に、 この回転軸の長さをシル 1 9の乗場側端部からレール枠 5のかご側端 部までの距離 Wよりも短く設定している。 FIG. 2 is a side view of the door device for the elevator shown in FIG. 1 as viewed from the right. The door device for the elevator is configured within the distance W from the end of the sill 19 to the car side of the rail frame 5. 13 has a rotation axis arranged in a direction substantially orthogonal to a plane along the surface of 3, and the length of this rotation axis is set between the landing side end of the sill 19 and the car side end of the rail frame 5. It is set shorter than the distance W.
上述した構成のエレべ一夕用ドア装置のモー夕は径方向を大きくとっている 特徴がある。 モー夕のトルクは一般的に磁石の表面積に依存するため、 軸方向 に伸ばすよりも、 径方向に伸ばす方が、 効率よく トルクを上げることができ、 したがって、 本発明はトルクを効率よく上げることができる。 このとき、 エレ ベ一夕用ドア装置のモ一夕に必要なトルクから、 2枚戸中央両開き戸を例にと ると、 モー夕軸が約 9 0 mm程度であるのに対し、 モー夕径はモ一夕軸方向長 さの 2〜3倍程度となり、 2 0 0〜3 0 0 mm程度となる。  The motor door of the elevator door device having the above-described configuration is characterized in that the radial direction is large. Since the torque of the motor generally depends on the surface area of the magnet, it is possible to increase the torque more efficiently in the radial direction than in the axial direction. Can be. At this time, due to the torque required for the door of the elevator overnight, taking the two-door central double door as an example, the motor shaft is about 90 mm, while the motor shaft is about 90 mm. The diameter is about 2 to 3 times the length in the axial direction, and is about 200 to 300 mm.
上述したエレべ一夕用ドア装置は、 かごドア 1 2， 1 3の表面に沿う平面も しくはそれと平行な平面内でドアモー夕 1の回転軸に取り付けた駆動プ一リ 2 が回転することになり、 従来のように駆動プーリ 2の径はレール枠 5の幅に直 接制約されることなく決定することができるようになる。 このため、 かご 2 2 の天井高さに拘わらず同じ仕様のものを適用でき、 またかごドア 1 2 , 1 3の 質量や加減速度によって決定する必要駆動力を伝達するために用いる駆動プ一 リ 2は、 その直径をレ一ル枠 5の高さに合せて自由に設計することができる。 このような駆動ブーリ 2は従来に比べて大きな径にすることができるので、 これに巻き付けるドアベルト 4は比較的大きな曲率半径で回動するようになり、 従来のようにその寿命を低下させたり、 駆動できるかごドア 1 2 , 1 3の質量 が制限されてしまうこともない。 このため、 かごドア 1 2， 1 3の高さを増し たり、 その表裏面に化粧板を貼り付けて美観性や意匠性を向上させることも容 易に行なえるようになる。  In the above-mentioned door device for the elevator, the drive pulley 2 attached to the rotating shaft of the door motor 1 rotates in a plane along the surface of the car doors 12 and 13 or in a plane parallel thereto. Thus, the diameter of the driving pulley 2 can be determined without being directly limited by the width of the rail frame 5 as in the conventional case. For this reason, the same specifications can be applied regardless of the ceiling height of the car 22 and the drive pulley used to transmit the required drive force determined by the mass and acceleration / deceleration of the car doors 12 and 13. 2 can be freely designed according to the height of the rail frame 5. Since such a drive bully 2 can be made larger in diameter than the conventional one, the door belt 4 wrapped around it can rotate with a relatively large radius of curvature, thereby shortening its life as in the past, The mass of the car doors 12 and 13 that can be driven is not limited. For this reason, the height of the car doors 12 and 13 can be increased, and decorative panels can be easily attached to the front and back surfaces to improve aesthetics and design.
特に、 ドアモー夕 1は、 かごドア 1 2 , 1 3の表面に沿う平面に対してほぼ 直交する方向に配置される回転軸を有すると共に、 この回転軸の長さをシル 1 9の乗場側端部からレール枠 5のかご側端部までの距離 Wよりも短く設定し たため、 ドアモ一夕 1をレール枠 5の幅内に配置することができ、 ドアモ一夕 1の回転軸に取り付けた駆動ブーリ 2の径を距離 Wとは無関係に設定すること ができるようになる。 In particular, the door motor 1 has a rotation axis arranged in a direction substantially orthogonal to a plane along the surface of the car doors 12 and 13, and the length of the rotation axis is set to the landing side end of the sill 19. From the section to the car end of the rail frame 5 should be shorter than W. As a result, it is possible to arrange the door mooring 1 within the width of the rail frame 5, and to set the diameter of the drive bully 2 attached to the rotating shaft of the door mooring 1 irrespective of the distance W. .
図 3および図 4は、 本発明の他の実施の形態によるエレべ一夕用ドァ装置の 要部拡大図およびその側面図である。  3 and 4 are an enlarged view and a side view of a main part of an elevator door device according to another embodiment of the present invention.
この実施の形態は、 ドアモ一夕 1の支持構造が先の実施の形態と異なり、 そ の他の部分はほぼ同一構成であるから同等物に同一符号を付けて詳細な説明を 省略する。 ドアモー夕 1は、 その軸方向中間部の外周に複数の支持部 2 8を形 成し、 これらの支持部 2 8とレール枠 5間にそれそれ防振ゴム等の弾性体 2 7 を介在させボルト 2 9などの固定手段で固定している。  This embodiment is different from the previous embodiment in the support structure of the door module 1 and the other parts have almost the same configuration. Therefore, the same components are denoted by the same reference numerals and detailed description is omitted. The door motor 1 has a plurality of support portions 28 formed on the outer periphery of the axial middle portion thereof, and an elastic body 27 such as a vibration-proof rubber is interposed between the support portions 28 and the rail frame 5. It is fixed with fixing means such as bolts 29.
レール枠 5に弾性体 2 7を介してドアモー夕 1を取り付けているため、 この 弾性体 2 7のばね定数、 減衰定数を適正に設定することにより、 レール枠 5に ドアモ一夕 1を直接取り付けた場合に比べて低振動、 低騒音のドア動作を実現 することができる。  Since the door motor 1 is mounted on the rail frame 5 via the elastic body 27, the door module 1 is directly mounted on the rail frame 5 by properly setting the spring constant and damping constant of the elastic body 27. Door operation with lower vibration and lower noise than in the case where the door is operated.
図 5は、 本発明のさらに他の実施の形態によるエレべ一夕用ドア装置を示す 正面図であり、 先の実施の形態との同等物には同一符号を付けて詳細な説明を 省略し、 相違部分についてのみ説明する。  FIG. 5 is a front view showing an elevator door apparatus according to still another embodiment of the present invention, and the same reference numerals are given to the same components as those in the previous embodiment, and detailed description is omitted. Only the differences will be described.
レール枠 5の左端部には従動プーリ 3に対向してほぼ同一平面内で回転する 駆動プーリ 2が配置され、 この駆動プーリ 2と同軸的に減速プーリ 2 6を設け ている。 この減速プーリ 2 6の近傍にはほぼ同一平面内で回転するモ一夕ブー リ 2 5を有するドアモ一夕 1が配置されている。 ほぼ同一平面内で回転するモ 一夕プ一リ 2 5と減速プ一リ 2 6間はベルト 2 4により連結され、 ほぼ同一平 面内で回転する減速プーリ 2 6と従動プーリ 3間はドアベルト 4によって連結 されている。 エレべ一夕用ドア装置は、 シル 1 9の乗場側端部からレール枠 5 のかご側端部までの距離内に構成しており、 特に、 ドアモー夕 1は、 かごドア 1 2 , 1 3の表面に沿う平面に対してほぼ直交する方向に配置される回転軸を 有すると共に、 この回転軸の長さをシル 1 9の乗場側端部からレール枠 5のか ご側端部までの距離よりも短く設定している。 At the left end of the rail frame 5, a driving pulley 2 that rotates in substantially the same plane as the driven pulley 3 is disposed, and a reduction pulley 26 is provided coaxially with the driving pulley 2. In the vicinity of the deceleration pulley 26, a door motor 1 having a motor shaft 25 that rotates in substantially the same plane is disposed. A belt 24 connects the motor pulley 25 and the deceleration pulley 26 that rotate in substantially the same plane, and a door belt rotates between the reduction pulley 26 and the driven pulley 3 that rotate in substantially the same plane. Connected by four. The door device for the elevator is located within the distance from the end of the sill 19 on the landing side to the end of the rail frame 5 on the car side. The axis of rotation, which is arranged in a direction substantially perpendicular to the plane along the surface of In addition, the length of the rotating shaft is set shorter than the distance from the landing end of the sill 19 to the car end of the rail frame 5.
従って、 ドアモ一夕 1の回転軸に取り付けたモ一夕プーリ 2 5と、 減速ブー リ 2 6と、 駆動プーリ 2は、 かごドア 1 2， 1 3の表面に沿う平面もしくはこ れに近接した平行な平面内でそれそれ回転することになり、 駆動プーリ 2、 モ —夕プーリ 2 5および減速プーリ 2 6の径はレール枠 5の幅に直接制約される ことなく決定することができるようになる。 このため、 かごドア 1 2 , 1 3の 質量や加減速度によって決定する必要駆動力を伝達するために用いる駆動ブー リ 2、 モー夕プ一リ 2 5および減速プ一リ 2 6は、 その直径をレール枠 5の高 さに合せて自由に設計することができる。  Therefore, the motor pulley 25 attached to the rotating shaft of the door motor 1, the deceleration burry 26, and the drive pulley 2 are arranged in a plane along or close to the surface of the car doors 12, 13. Each of them rotates in a parallel plane, so that the diameters of the driving pulley 2, the motor pulley 25 and the reduction pulley 26 can be determined without being directly limited by the width of the rail frame 5. Become. For this reason, the drive bull 2, the motor pulley 25 and the deceleration pulley 26 used to transmit the required drive force determined by the mass and acceleration / deceleration of the car doors 12 and 13 have the same diameter. Can be designed freely according to the height of the rail frame 5.
このような駆動プーリ 2、 モ一夕プーリ 2 5および減速プーリ 2 6は従来に 比べて大きな径にすることができるので、 これに巻き付けるドアベルト 4 , ベ ルト 2 4は比較的大きな曲率半径で回動するようになり、 従来のようにその寿 命を低下させたり、 駆動できるかごドア 1 2 , 1 3の質量が制限されてしまう こともない。 また減速プーリ 2 6は容易に減速比を大きくすることができるの で、 かごドア 1 2 , 1 3の高さを増したり、 その表裏面に化粧板を貼り付けて 美観性や意匠性を向上させることも容易に行なえるようになる。  Since the driving pulley 2, the motor pulley 25 and the deceleration pulley 26 can have a larger diameter than the conventional one, the door belt 4 and the belt 24 wound around the pulley 2 and the belt 24 have a relatively large radius of curvature. As a result, the life of the car doors 12 and 13 that can be driven is not limited as in the conventional case. In addition, since the reduction ratio of the reduction pulley 26 can be easily increased, the height of the car doors 12 and 13 can be increased, and decorative panels can be attached to the front and back surfaces to improve aesthetics and design. Can be easily performed.
また、 図 5に示す構成においては、 減速比を大きくとることができるので、 2枚戸中央両開き戸を例にとると、 モー夕径はモ一夕軸方向長さの 1 . 5〜2 倍程度となり、 1 5 0〜2 0 O mm程度と、 図 1に示す構成に比べて、 モ一夕 自体を小さくすることができる。  In addition, in the configuration shown in Fig. 5, the reduction ratio can be increased, so that taking the double door central double door as an example, the motor diameter is 1.5 to 2 times the axial length of the motor. This is about 150 to 20 O mm, which is smaller than that of the configuration shown in FIG.
また、 図 5に示す構成におけるベルト 4、 2 4に係合するプーリ 2、 2 6を 有し静粛性を確保する減速装置は、ベルト 4とベルト 2 4による 2段のパネ作 用によりドアモー夕 1の振動がかごドア 1 2、 1 3に伝達されるのを防止する 機能を有する。 このため、 図 5に示す実施例は、 かごドアの表面に沿う平面に 対してほぼ直交する方向に配置される回転軸を有する効率の良い高トルクのド ァモ一夕 1と、ペルト 4、 2 4に係合するプーリ 2、 2 6を有し静粛性を確保す る減速装置から構成されるので、 エレべ一夕のドア制御に要求される高トルク と静粛性を同時に満足するべス卜の組み合わせとしての特徴を有する。 In the configuration shown in FIG. 5, the speed reducer having the pulleys 2 and 26 engaged with the belts 4 and 24 to ensure quietness is provided by a two-stage panel operation by the belt 4 and the belt 24, and the door motor is operated by the door. It has a function to prevent the vibration of 1 from being transmitted to the car doors 12 and 13. For this reason, the embodiment shown in FIG. 5 is an efficient, high-torque drive having a rotating shaft arranged in a direction substantially orthogonal to a plane along the surface of the car door. It is composed of a speed reducer that has quietness and has pulleys 2 and 26 that engage with the pelts 4 and 24. It has the characteristic of a combination of the best that satisfies both torque and quietness at the same time.
図 6は、 本発明のさらに他の実施の形態によるエレべ一夕用ドア装置を示す 正面図であり、 先の実施の形態との同等物には同一符号を付けて詳細な説明を 省略し、 相違部分についてのみ説明する。  FIG. 6 is a front view showing a door device for an elevator according to still another embodiment of the present invention. The same reference numerals are given to the same components as those in the previous embodiment, and the detailed description is omitted. Only the differences will be described.
レール枠 5の上部に載置したモ一夕ブラケヅト 3 0は、 その片側をヒンジ 2 9 .によって回動可能に取り付け、 また他側はばね 2 8によって上方に押し上 げるように支持しており、 このモ一夕ブラケヅト 3 0内にドアモータ 1が取り 付けられている。 このドアモ一夕 1は、 かごドア 1 2， 1 3の表面に沿う平面 に対してほぼ直交する方向に配置される回転軸を有すると共に、 この回転軸の 長さをシル 1 9の乗場側端部からレール枠 5のかご側端部までの距離 Wよりも 短く設定している。 従って、 その回転軸に取り付けたモー夕プーリ 2 5は、 か ごドア 1 2， 1 3の表面に沿う平面もしくはその近傍の平行な平面内で回転す ることになる。 またレール枠 5の左端部に配置した駆動プ一リ 2と同軸的に減 速プーリ 2 6が設けられ、 この減速プ一リ 2 6とモ一夕プーリ 2 5はほぼ同一 平面内に配置されてベルト 2 4によって連結されている。  The module bracket 30 mounted on the upper part of the rail frame 5 has one side rotatably mounted by a hinge 29 and the other side supported by a spring 28 so as to be pushed upward. The door motor 1 is mounted in the module bracket 30. This door module 1 has a rotation axis arranged in a direction substantially orthogonal to a plane along the surface of the car doors 12 and 13, and the length of this rotation axis is determined by the end of the sill 19 on the landing side. Is set shorter than the distance W from the section to the car side end of the rail frame 5. Therefore, the motor pulley 25 attached to the rotating shaft rotates in a plane along the surface of the car doors 12 and 13 or in a parallel plane in the vicinity thereof. Further, a deceleration pulley 26 is provided coaxially with the drive pulley 2 disposed at the left end of the rail frame 5, and the deceleration pulley 26 and the motor pulley 25 are disposed substantially in the same plane. And are connected by a belt 24.
ドアモ一夕 1はばね 2 8によって上方に押されているのでベルト 2 4のテン シヨンを確保することができると共に、 ばね 2 8のばね定数を適性に設定する ことにより、 図 3および図 4に示した実施の形態の場合と同様に低振動、 低騒 音でのドァ動作を実現することができる。  Since the door door 1 is pushed upward by the spring 28, the tension of the belt 24 can be secured, and by setting the spring constant of the spring 28 appropriately, it is possible to obtain the results shown in FIGS. 3 and 4. As in the case of the illustrated embodiment, the door operation with low vibration and low noise can be realized.
図 6に示す実施例も、 かごドアの表面に沿う平面に対してほぼ直交する方向 に配置される回転軸を有する効率の良い高トルクのドァモ一夕 1と、ベルト 4、 2 4に係合するプーリ 2、 2 6を有し静粛性を確保する減速装置殻構成される。 このため、 図 6に示す実施例もエレべ一夕のドア制御に要求される高トルクと 静粛性を同時に満足するべストの組み合わせとしての特徴を有する。 尚、 本発明の実施の形態のなかでドアモー夕 1は必要な場合、 速度、 磁極等 のセンサも含んでもよい。 産業上の利用可能性 The embodiment shown in FIG. 6 also engages with an efficient high-torque drum 1 having a rotation axis arranged in a direction substantially perpendicular to a plane along the surface of the car door, and belts 4 and 24. Speed reducer shell that has the pulleys 2 and 26 to ensure quietness. For this reason, the embodiment shown in FIG. 6 also has a feature as a combination of the best that simultaneously satisfies the high torque and the quietness required for the door control of the elevator. In the embodiment of the present invention, if necessary, the door motor 1 may include sensors for speed, magnetic pole, and the like. Industrial applicability
以上説明したように本発明のエレべ一夕用ドア装置は、 ドアモー夕が、 かご ドアの表面に沿う平面に対してほぼ直交する方向に配置される回転軸を有する と共に、 この回転軸の長さをシルの乗場側端部からレール枠のかご側端部まで の距離よりも短く設定したため、 モー夕の径方向を大きくとることができ、 し たがってモ一夕のトルクを効率よく上げることができ、 また、 レール枠の幅を 増すことなく、 ドアベルトの曲率半径を比較的大きくすることができるのでそ の寿命を向上させると共に、 かごドアの質量増大に対処することができる。  As described above, the door device for an elevator according to the present invention has a door motor having a rotation axis arranged in a direction substantially orthogonal to a plane along the surface of the car door, and a length of the rotation axis. The distance between the landing side end of the sill and the car side end of the rail frame is set shorter, so that the radial direction of the motor can be made larger, and therefore the torque of the motor can be increased efficiently. In addition, since the radius of curvature of the door belt can be made relatively large without increasing the width of the rail frame, the life of the door belt can be improved and the increase in the weight of the car door can be dealt with.
