Description

この発明は、例えば高層ビルに設置される超高速エレベータなど、かごの遮音性が求められるエレベータのかごドア装置に関するものである。   The present invention relates to an elevator car door device that requires sound insulation of a car such as an ultra-high speed elevator installed in a high-rise building, for example.

高層ビルに設置されるエレベータでは、かごの昇降速度が毎分数百メートルに達し、走行中のかごの周囲で発生する風切り音が非常に大きくなる。このため、風切り音の発生を極力防いだり、発生した風切り音がかご室内に流入するのを抑制したりするための手段が講じられている。   In an elevator installed in a high-rise building, the ascending / descending speed of the car reaches several hundred meters per minute, and the wind noise generated around the moving car becomes very large. For this reason, measures are taken to prevent the generation of wind noise as much as possible and to suppress the generated wind noise from flowing into the car room.

風切り音の発生を抑制するためには、例えば、かご室の形状を凹凸の少ない形状にしたり、かご室の上下に流線形のカバーを設置したりして、気流を滑らかにする方法がある。また、従来のエレベータでは、風切り音のかご室内への流入を抑制するため、かご出入口の上下とドアパネルの上下とに密着部材が設けられており、ドアパネルが閉じたとき、密着部材同士が密着して、かごドア周りの隙間が塞がれる（例えば、特許文献１参照）。   In order to suppress the generation of wind noise, there are methods of smoothing the airflow by, for example, making the shape of the cab with less unevenness or installing streamline covers above and below the cab. In addition, in conventional elevators, in order to suppress the flow of wind noise into the car room, close contact members are provided above and below the car doorway and above and below the door panel. When the door panel is closed, the close contact members are in close contact with each other. Thus, the gap around the car door is closed (see, for example, Patent Document 1).

さらに、従来の他のエレベータでは、上下方向に変位する閉塞装置がかごドアに設けられており、かごドアの全閉時に、かごドアとかご敷居との間の隙間が閉塞装置により塞がれる（例えば、特許文献２参照）。   Further, in other conventional elevators, the car door is provided with a closing device that is displaced in the vertical direction, and when the car door is fully closed, the gap between the car door and the car sill is closed by the closing device ( For example, see Patent Document 2).

特開平１０−１２０３４９号公報JP-A-10-120349 特開２００３−３０６２８６号公報JP 2003-306286 A

特許文献１に示されたような従来のエレベータでは、戸閉時にかご出入口の上下で密着部材が同時に当接する必要があり、非常に高度な工作性や据付性が要求される。また、非常に大きな戸閉力によって戸閉しなければ、かご出入口の上下で密着部材同士を密着させることが困難となるため、ドアモータの負荷が大きくなる。   In the conventional elevator as shown in Patent Document 1, it is necessary that the close contact members simultaneously come in contact with the upper and lower sides of the car doorway when the door is closed, and very high workability and installation are required. In addition, if the door is not closed by a very large door closing force, it is difficult to bring the contact members into close contact with each other above and below the car doorway, so the load on the door motor increases.

さらに、かごドアを吊り下げるドアレール及びかごドアを開閉する駆動装置は、かご枠の上部に取り付けられているが、かご室は防振ゴムを介してかご枠の下部上に支持されているため、かご室に大勢の乗客が乗り込んだ際には、かご室がかご枠に対して２〜３ｍｍ程度沈み込む場合がある。これによって、かごドアとかご敷居との間の隙間が広がることになり、かごドアの下部に設けたシール部材がかご敷居に接触しなくなる恐れがある。   Furthermore, the door rail that suspends the car door and the drive device that opens and closes the car door are attached to the upper part of the car frame, but the car room is supported on the lower part of the car frame via anti-vibration rubber, When a large number of passengers get into the car room, the car room may sink about 2 to 3 mm from the car frame. This widens the gap between the car door and the car sill, and the seal member provided at the lower part of the car door may not come into contact with the car sill.

この解決手段として特許文献２に示すような閉塞装置があるが、構成が複雑であり、かごドアの重量アップが懸念される。また、万一、停電等により乗客がかご室に閉じ込められた場合、閉塞装置からかご敷居に向かって押圧力が発生しているため、手動でかごドアを開く際に大きな抵抗が生じる。   As a means for solving this problem, there is a closing device as shown in Patent Document 2, but the configuration is complicated and there is a concern that the weight of the car door may increase. Also, in the unlikely event that a passenger is trapped in a car room due to a power failure or the like, since a pressing force is generated from the closing device toward the car sill, a large resistance is generated when the car door is manually opened.

さらに、急激な気圧変動による耳の閉塞感を緩和させるための気圧制御装置を搭載したエレベータにおいては、かごの走行中に加減圧を行うため、かご室の内外で１０００Ｐａ相当の気圧差が生じる。これにより、例えばかご出入口が２平方メートルの場合、かごドアは２０００Ｎの力を受けることになる。また、加圧か減圧かによって力を受ける方向が異なるため、かごドアには前後両方向への微小変動が生じる。   Furthermore, in an elevator equipped with a barometric pressure control device for relieving the feeling of ear blockage due to sudden pressure fluctuations, a pressure difference equivalent to 1000 Pa occurs inside and outside the car room because pressure is increased and decreased while the car is running. Thus, for example, when the car doorway is 2 square meters, the car door receives a force of 2000N. Further, since the direction of receiving the force differs depending on whether the pressure is applied or the pressure is reduced, the car door undergoes minute fluctuations in both the front and rear directions.

従って、超高速エレベータ等の高い遮音性能が要求されるエレベータにおいては、かご枠に対するかご室の上下方向への変位や、気圧制御装置によるかごドアの前後方向への変位に対しても、かごドアの下部とかご敷居との間の隙間を閉塞状態を維持し、かつ、手動でかごドアを開く際に大きな抵抗が生じないようにすることが求められる。   Therefore, in elevators that require high sound insulation performance, such as ultra-high speed elevators, the car doors can be protected against vertical displacement of the car room with respect to the car frame and displacement of the car door in the front-rear direction by the atmospheric pressure control device. It is required that the gap between the lower part of the car and the car sill be kept closed, and that a large resistance is not generated when the car door is manually opened.

この発明は、上記のような課題を解決するためになされたものであり、簡単な構成により、かご枠に対するかご室の上下方向への変位やかごドアパネルの前後方向への変位に対して、高い遮音性能を維持することができ、ドアモータの負荷の増大を抑制することができ、手動でかごドアを開く際に大きな抵抗が生じないようにすることができるエレベータのかごドア装置を得ることを目的とする。   The present invention has been made to solve the above-described problems, and is high with respect to the vertical displacement of the cab relative to the car frame and the longitudinal displacement of the car door panel with a simple configuration. An object of the present invention is to provide an elevator car door device that can maintain sound insulation performance, can suppress an increase in the load on the door motor, and can prevent large resistance when manually opening the car door. And

この発明に係るエレベータのかごドア装置は、かご出入口を開閉するかごドアパネル、かご出入口の下部に設けられ、かごドアパネルの開閉方向に沿って設けられた第１及び第２の敷居溝を有するかご敷居、かごドアパネルの下部に設けられ、第１の敷居溝に挿入される戸の脚、第１の敷居溝の側面に接するようにかごドアパネルの下部に設けられ、かごドアパネルの開閉動作時に第１の敷居溝の側面に沿って摺動される弾性体製の第１のシール部材、及び第２の敷居溝の側面に接するようにかごドアパネルの下部に設けられ、かごドアパネルの開閉動作時に第２の敷居溝の側面に沿って摺動される弾性体製の第２のシール部材を備えている。   An elevator car door device according to the present invention includes a car door panel that opens and closes a car doorway, and a car sill that is provided at a lower portion of the car doorway and has first and second sill grooves provided along the opening and closing direction of the car door panel. The door leg is provided in the lower part of the car door panel and is inserted in the first sill groove, and is provided in the lower part of the car door panel so as to contact the side surface of the first sill groove. A first seal member made of an elastic body that slides along the side surface of the sill groove and a lower part of the car door panel so as to be in contact with the side surface of the second sill groove. A second seal member made of an elastic body is provided that is slid along the side surface of the sill groove.

この発明のエレベータのかごドア装置は、戸の脚が挿入される第１の敷居溝に加えて第２の敷居溝をかご敷居に設け、第１の敷居溝の側面に接する第１のシール部材と第２の敷居溝の側面に接する第２のシール部材とをかごドアパネルの下部に設けたので、簡単な構成により、かご枠に対するかご室の上下方向への変位は第１及び第２のシール部材の上下方向への摺動により吸収し、かごドアパネルの前後方向への変位は第１及び第２のシール部材の弾性変形により吸収することができ、これにより高い遮音性能を維持することができる。また、第１及び第２のシール部材は、かごドアパネルの開閉動作時に第１及び第２の敷居溝の側面に沿って摺動されるので、大きな戸閉力は必要なく、ドアモータの負荷の増大を抑制することができ、さらに、手動でかごドアを開く際に大きな抵抗が生じさせない。   The elevator car door device according to the present invention includes a first seal member that is provided with a second sill groove in the car sill in addition to the first sill groove into which the door leg is inserted, and is in contact with a side surface of the first sill groove. And the second seal member in contact with the side surface of the second sill groove at the lower portion of the car door panel, the vertical displacement of the car room relative to the car frame is the first and second seals with a simple structure. Absorbed by sliding the member in the vertical direction, the displacement of the car door panel in the front-rear direction can be absorbed by the elastic deformation of the first and second sealing members, thereby maintaining high sound insulation performance. . Further, since the first and second sealing members are slid along the side surfaces of the first and second sill grooves when the car door panel is opened and closed, a large door closing force is not required, and the load of the door motor is increased. Moreover, when the car door is manually opened, a great resistance is not generated.

図２は図１のＩＩ−ＩＩ線に沿う断面図であり、かごドアパネル３の下端部の縦断面を示している。また、図２において、かごドアパネル３の右側がかご室側、左側が乗場側である。かご敷居１０には、かごドアパネル３の開閉方向に沿って設けられた第１及び第２の敷居溝１１，１２が互いに間隔をおいて設けられている。第２の敷居溝１２は、第１の敷居溝１１の乗場側に配置されている。   FIG. 2 is a cross-sectional view taken along line II-II in FIG. 1 and shows a vertical cross section of the lower end portion of the car door panel 3. In FIG. 2, the right side of the car door panel 3 is the cab side, and the left side is the landing side. The car sill 10 is provided with first and second sill grooves 11, 12 provided along the opening / closing direction of the car door panel 3 at intervals. The second threshold groove 12 is arranged on the landing side of the first threshold groove 11.

The second sill groove 12 has a second cab side surface 12a, a second landing side surface 12b, and a second bottom surface 12c. The depth of the second threshold groove 12 is the same as the depth of the first threshold groove 11. Further, the first and second sill grooves 11 and 12 are arranged directly below the car door panel 3 within the range of the thickness of the car door panel 3.

かごドアパネル３の内側には、複数の吸音部材１３ａ〜１３ｄが固定されている。   Inside the car door panel 3, a plurality of sound absorbing members 13a to 13d are fixed.

かごドアパネル３の下部には、下部補強部材１４が固定されている。下部補強部材１４は、かごドアパネル３の幅方向（図１の左右方向）の全体に渡って設けられている。また、下部補強部材１４は、かごドアパネル３の裏面に接着又は溶接された接合部１４ａと、かごドアパネル３の下端部の裏面に対向する脚取付部１４ｂとを有している。接合部１４ａ及び脚取付部１４ｂは、平板を折り曲げることにより形成されている。   A lower reinforcing member 14 is fixed to the lower portion of the car door panel 3. The lower reinforcing member 14 is provided over the entire width direction of the car door panel 3 (left and right direction in FIG. 1). Further, the lower reinforcing member 14 has a joint portion 14 a bonded or welded to the back surface of the car door panel 3 and a leg mounting portion 14 b facing the back surface of the lower end portion of the car door panel 3. The joint portion 14a and the leg attachment portion 14b are formed by bending a flat plate.

脚取付部１４ｂには、複数の戸の脚１５がかごドアパネル３の幅方向に互いに間隔をおいてねじ止めされている。戸の脚１５は、第１の敷居溝１１に挿入されている。かごドアパネル３の開閉動作時には、戸の脚１５は第１の敷居溝１１内を移動される。これにより、かごドアパネル３の開閉動作時のガタつき等が抑制される。   A plurality of door legs 15 are screwed to the leg attachment portion 14b at intervals in the width direction of the car door panel 3. The door leg 15 is inserted into the first threshold groove 11. During the opening / closing operation of the car door panel 3, the door leg 15 is moved in the first sill groove 11. Thereby, rattling or the like during the opening / closing operation of the car door panel 3 is suppressed.

脚取付部１４ｂには、第１の押さえ金具１６を介して、複数の第１のシール部材１７が取り付けられている。第１の押さえ金具１６は、脚取付部１４ｂにねじ止めされている。第１のシール部材１７の上端部は、第１の押さえ金具１６と脚取付部１４ｂとの間に挟持されている。第１のシール部材１７は、戸の脚１５が取り付けられている部分を除くかごドアパネル３の幅方向の全体に設けられている。   A plurality of first seal members 17 are attached to the leg attachment portion 14b via the first presser fitting 16. The first presser fitting 16 is screwed to the leg mounting portion 14b. The upper end portion of the first seal member 17 is sandwiched between the first presser fitting 16 and the leg attachment portion 14b. The first seal member 17 is provided in the entire width direction of the car door panel 3 excluding a portion where the door leg 15 is attached.

また、第１のシール部材１７は、ゴム等の弾性体により構成されており、その下端部は第１のかご室側側面１１ａに接触して微小に弾性変形されている。これにより、第１のシール部材１７は、かごドアパネル３の開閉動作時に第１のかご室側側面１１ａに沿って摺動される。   The first seal member 17 is made of an elastic body such as rubber, and its lower end is in contact with the first cab side surface 11a and is elastically deformed minutely. Thus, the first seal member 17 is slid along the first car room side surface 11a when the car door panel 3 is opened and closed.

下部補強部材１４の接合部１４ａの裏面には、断面Ｌ字形の固定部材１８が接着又は溶接により固定されている。固定部材１８は、水平部１８ａを有している。水平部１８ａには、ビス１９により取付金具２０が取り付けられている。ビス１９は、取付金具２０の上面側から鉛直に締め込まれている。   A fixing member 18 having an L-shaped cross section is fixed to the back surface of the joint portion 14a of the lower reinforcing member 14 by adhesion or welding. The fixing member 18 has a horizontal portion 18a. A mounting bracket 20 is attached to the horizontal portion 18a with screws 19. The screw 19 is tightened vertically from the upper surface side of the mounting bracket 20.

取付金具２０には、遮音板２１及び第２の押さえ金具２２がねじ止めされている。遮音板２１の下端部は、第２の敷居溝１２内に挿入されている。また、遮音板２１は、鉄鋼製であり、かごドアパネル３の幅方向の全体に渡って連続して設けられている。   A sound insulating plate 21 and a second presser fitting 22 are screwed to the mounting bracket 20. The lower end of the sound insulating plate 21 is inserted into the second threshold groove 12. The sound insulating plate 21 is made of steel and is continuously provided over the entire width direction of the car door panel 3.

第２の押さえ金具２２と遮音板２１との間には、第２のシール部材２３が挟持されている。第２のシール部材２３は、かごドアパネル３の幅方向の全体に渡って連続して設けられている。   A second seal member 23 is sandwiched between the second presser fitting 22 and the sound insulating plate 21. The second seal member 23 is continuously provided over the entire width direction of the car door panel 3.

また、第２のシール部材２３は、ゴム等の弾性体により構成されており、その下端部は第２の乗場側側面１２ｂに接触して微小に弾性変形されている。これにより、第２のシール部材２３は、かごドアパネル３の開閉動作時に第２の乗場側側面１２ｂに沿って摺動される。   The second seal member 23 is made of an elastic body such as rubber, and its lower end is in contact with the second landing side surface 12b and is elastically deformed minutely. Thus, the second seal member 23 is slid along the second landing side surface 12b when the car door panel 3 is opened and closed.

下部補強部材１４には、取付金具２０や第２の押さえ金具２２に対向する裏板（カバー）２４が取り付けられている。裏板２４は、かごドアパネル３の幅方向の全体に渡って連続して設けられており、複数のビス２５により下部補強部材１４の上端部近傍に取り付けられている。   A back plate (cover) 24 is attached to the lower reinforcing member 14 so as to face the mounting bracket 20 and the second pressing bracket 22. The back plate 24 is provided continuously over the entire width direction of the car door panel 3, and is attached to the vicinity of the upper end portion of the lower reinforcing member 14 with a plurality of screws 25.

このようなかごドア装置では、戸の脚１５が挿入される第１の敷居溝１１に加えて第２の敷居溝１２をかご敷居１０に設け、第１のかご室側側面１１ａに接する第１のシール部材１７と第２の乗場側側面１２ｂに接する第２のシール部材２３とをかごドアパネル３の下部に設けたので、簡単な構成により、かご枠に対するかご室の上下方向への変位は第１及び第２のシール部材１７，２３の上下方向への摺動により吸収し、かごドアパネル３の前後方向（図２の左右方向）への変位は第１及び第２のシール部材１７，２３の弾性変形により吸収することができ、これにより高い遮音性能を維持することができる。   In such a car door device, in addition to the first sill groove 11 into which the door leg 15 is inserted, a second sill groove 12 is provided in the car sill 10, and the first sill is in contact with the first cab side 11a. Since the second seal member 17 and the second seal member 23 in contact with the second landing side surface 12b are provided in the lower part of the car door panel 3, the vertical displacement of the car room relative to the car frame can be reduced with a simple configuration. The first and second seal members 17 and 23 are absorbed by sliding in the vertical direction, and the displacement of the car door panel 3 in the front-rear direction (left and right direction in FIG. 2) is caused by the first and second seal members 17 and 23. It can be absorbed by elastic deformation, thereby maintaining a high sound insulation performance.

また、第１及び第２のシール部材１７，２３は、かごドアパネルの開閉動作時に第１及び第２の敷居溝１１，１２の側面１１ａ，１２ｂに沿って摺動されるので、大きな戸閉力は必要なく、ドアモータ７の負荷の増大を抑制することができ、さらに、手動でかごドア２を開く際に大きな抵抗が生じさせない。   Moreover, since the 1st and 2nd sealing members 17 and 23 are slid along the side surfaces 11a and 12b of the 1st and 2nd sill grooves 11 and 12 at the time of opening / closing operation | movement of a car door panel, big door closing force Is not necessary, and an increase in the load of the door motor 7 can be suppressed. Further, when the car door 2 is manually opened, a large resistance is not generated.
