　本発明は、エレベータ装置に係り、特に気密構造の乗りかごを備えたエレベータ装置に関する。 The present invention relates to an elevator apparatus, and more particularly to an elevator apparatus provided with a car having an airtight structure.
　長行程のエレベータには、乗りかごが昇降路内を昇降するときに、吸気ブロア及び排気ブロアなどを制御して乗りかご内の加圧及び減圧を行い、単位時間あたりの気圧の変化量を一定に保ち、乗客に与える不快感を緩和する気圧制御装置を備えたものがある。そして、このようなエレベータでは、乗りかご内の気圧を外側の気圧と異なるように変化させるため、乗りかごの気密性を高める必要がある。　
　乗りかごの気密性を高める技術として、特許文献１に記載される技術が知られている。特許文献１には、前面に出入口用の開口部を有するかご室、このかご室の上記開口部を開閉するドアパネル、及び上記かご室内の気圧を制御する気圧制御装置と、を備えるエレベータの乗りかごが開示されている。そして幕板及び入口柱に、断面コ字状のホルダを設け、このホルダ内に対向するよう配される一対のシール部材を配し、ドアパネルに上記ホルダに対応するよう接合部材を設け、少なくともドアパネルの閉合時に上記接合部材を上記ホルダ内に介在させ、上記かご室内の気圧の負荷に応じて接合部材を一対のシール部材の何れか一方に密着させ、乗りかごの開口部とドアパネル間を密閉する構成が記載されている。 For long-range elevators, when the car goes up and down in the hoistway, the intake blower and exhaust blower are controlled to pressurize and depressurize the car, and the amount of change in air pressure per unit time is constant. There are those equipped with a barometric pressure control device that keeps the vehicle uncomfortable and reduces the discomfort given to passengers. In such an elevator, since the air pressure in the car is changed so as to be different from the air pressure outside, it is necessary to improve the airtightness of the car.
As a technique for improving the airtightness of a car, a technique described in Patent Document 1 is known. Patent Document 1 discloses an elevator car comprising: a car room having an opening for entrance and exit on the front surface; a door panel that opens and closes the opening of the car room; and an air pressure control device that controls the air pressure in the car room. Is disclosed. Then, a holder having a U-shaped cross section is provided on the curtain plate and the entrance post, a pair of seal members arranged to face the holder are provided, a joining member is provided on the door panel so as to correspond to the holder, and at least the door panel When the door is closed, the joining member is interposed in the holder, and the joining member is brought into close contact with either one of the pair of seal members according to the atmospheric pressure load in the car room, thereby sealing between the opening of the car and the door panel. The configuration is described.

　以下、図面を用いて本発明の実施例について説明する。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.
　まず、本発明が適用されるエレベータ装置の一般的な構成を説明する。エレベータ装置は良く知られているように建屋に設けられた昇降路の内部に収納されている。　
　図２は、本発明が適用されるエレベータ装置を示す概略構成図である。　
　図２において、エレベータ装置１は、昇降路２１の頂部部分に形成した機械室２２内に巻上機２３が載置され、ボルト等の固定具によって機械室２２の床面に固定されている。巻上機２３は、本図では詳細に記載していないが、複数本の主ロープ２４を懸架するためのシーブを有する。シーブから延びる主ロープ２４の一端は、反らせプーリ２５を介してつり合いおもり２６の上端に連結されており、他端は乗りかご２の上端に連結されている。 First, a general configuration of an elevator apparatus to which the present invention is applied will be described. As is well known, an elevator apparatus is housed in a hoistway provided in a building.
FIG. 2 is a schematic configuration diagram illustrating an elevator apparatus to which the present invention is applied.
In FIG. 2, the elevator apparatus 1 has a hoisting machine 23 placed in a machine room 22 formed at the top of a hoistway 21, and is fixed to the floor surface of the machine room 22 by a fixture such as a bolt. Although not shown in detail in the drawing, the hoisting machine 23 has a sheave for suspending a plurality of main ropes 24. One end of the main rope 24 extending from the sheave is connected to the upper end of the counterweight 26 via a warp pulley 25, and the other end is connected to the upper end of the car 2.
　次に、エレベータ装置１の稼働時の各部の動作について説明する。　
　巻上機２３が稼働し、シーブが回転すると、その際の主ロープ２４とシーブとの間の摩擦によって、シーブに懸架された主ロープ２４がシーブの回転方向に沿って移動する。そして、主ロープ２４の動きに従って、つり合いおもり２６及び乗りかご２が上下に互いに反対方向に移動する。なお、図２では省略しているが、乗りかご２の昇降を円滑にするため、実際のエレベータ装置１では、乗りかご２及びつり合いおもり２６の側面をガイドレールと呼ばれる案内部品で案内する構成となっている。　
　このようなエレベータ装置１においては、図示しない制御器によって運行指令が、巻上機２３を構成する電動機や制動機構等に与えられ、この運行指令によって乗りかご２が建築物の所定の階層に向けて昇降動作するものである。以上においてはエレベータ装置１を簡略化して説明してあるが、実際は更に種々の構成要素が付加されているものである。 Next, operation | movement of each part at the time of operation | movement of the elevator apparatus 1 is demonstrated.
When the hoisting machine 23 is operated and the sheave rotates, the main rope 24 suspended on the sheave moves along the sheave rotation direction by friction between the main rope 24 and the sheave. Then, according to the movement of the main rope 24, the counterweight 26 and the car 2 move up and down in opposite directions. Although omitted in FIG. 2, in order to make the car 2 ascend and descend smoothly, in the actual elevator apparatus 1, the side surfaces of the car 2 and the counterweight 26 are guided by guide parts called guide rails. It has become.
In such an elevator apparatus 1, an operation command is given by a controller (not shown) to an electric motor, a braking mechanism, or the like constituting the hoisting machine 23, and the car 2 is directed to a predetermined level of the building by the operation command. It moves up and down. Although the elevator apparatus 1 has been described in a simplified manner in the above, actually, various components are further added.
　次に乗りかご２について説明する。図１は、本実施例におけるエレベータ装置１の要部である乗りかごの外観斜視図である。　
　乗りかご２は、前面側に出入口用のかご戸３を有し、その上部には気圧制御装置としての吸気ブロア４ａ及び排気ブロア４ｂが設けられている。気圧制御装置は、乗りかご２が昇降路２１内を昇降するときに、吸気ブロア４ａ及び排気ブロア４ｂなどを制御して乗りかご２内の加圧及び減圧を行い、単位時間あたりの気圧の変化量を一定に保ち、乗客に与える不快感を緩和するものである。 Next, the car 2 will be described.

The car 2 has an entrance / exit car door 3 on the front side, and an intake blower 4a and an exhaust blower 4b as an air pressure control device are provided on the upper part thereof. When the car 2 moves up and down in the hoistway 21, the air pressure control device controls the intake blower 4a and the exhaust blower 4b to pressurize and depressurize the car 2, and change the air pressure per unit time. The amount is kept constant and the discomfort given to passengers is alleviated.
　上述したように乗りかご２には、開閉可能なかご戸３が設けられているため、かご戸３が閉じられた状態でもその近傍から乗りかご２の内外が容易に連通してしまうと、気圧制御装置による気圧制御効率を低下させてしまう原因となる。そこで、乗りかご２の近傍に気密構造を構成している。次に、この気密構造について説明する。 As described above, since the car 2 is provided with the car door 3 that can be opened and closed, even when the car door 3 is closed, if the inside and outside of the car 2 easily communicate from the vicinity, It becomes the cause of reducing the atmospheric pressure control efficiency by the control device.

　可撓性部材１３は、ブラケット１４の水平片１４ａと対向すると共に、少なくとも通常時に水平片１４ａとの間にくさび状の間隙１９を有して配置される上部薄板材１３ｂ（第１の平板状部）と、上部薄板材１３ｂ（第１の平板状部）の一端から延設されると共に、少なくとも通常時に上部薄板材１３ｂ（第１の平板状部）との間にくさび状の間隙２０を有し、かつ通常時にかごシル７との間に略水平の間隙１１ａを有して配置される下部薄板材１３ｃ（第２の平板状部）とを備える。換言すれば、可撓性部材１３は、少なくとも通常時において、縦断面形状が乗りかご２の内側へと向かい下方へ傾斜する上部薄板材１３ｂ（第１の平板状部）と、上部薄板材１３ｂ（第１の平板状部）の乗りかご２の内側端部である連結部１３ｅにて折り返され、乗りかご２の外側へと向かう下部薄板材１３ｃ（第２の平板状部）を備える。なお、下部薄板材１３ｃ（第２の平板状部）の連結部１３ｅと反対側の端部、すなわち、乗りかご２の外側へと向かう端部は、特に、固定されることなく自由端１３ｆを構成している。ここで通常時とは、上述の吸気ブロア４ａ及び排気ブロア４ｂを有する気圧制御装置による乗りかご２内の加圧及び減圧の何れの状態ともされておらず、乗りかご２内の圧力調整がなされていない状態を意味する。例えば、乗りかご２がホール呼びのあった所望の階床へ到達し停止した状態、或いは、乗りかご２が昇降路２１内において比較的低階層を昇降中などが通常時に相当する。 As shown in FIG. 4, the upper horizontal member 13 a of the flexible member 13 is sandwiched between the horizontal piece 16 b of the movable presser 16 and the horizontal piece 17 a of the presser 17, and the flexible member 13 is attached to the car door 3. It comes to support.
The flexible member 13 opposes the horizontal piece 14a of the bracket 14 and is disposed with a wedge-shaped gap 19 at least between the horizontal piece 14a and the upper thin plate member 13b (first flat plate shape). Portion) and an upper thin plate member 13b (first flat plate portion) extending from one end of the upper thin plate member 13b (first flat plate portion). And a lower thin plate member 13c (second flat plate-like portion) disposed with a substantially horizontal gap 11a between the cage sill 7 and the cage sill 7 at a normal time. In other words, the flexible member 13 includes an upper thin plate member 13b (first flat plate portion) whose vertical cross-sectional shape inclines downward toward the inside of the car 2, and an upper thin plate member 13b at least normally. A lower thin plate member 13c (second flat plate portion) that is folded back at a connecting portion 13e that is an inner end portion of the car 2 of the (first flat plate portion) and goes to the outside of the car 2 is provided. Note that the end of the lower thin plate member 13c (second flat plate portion) opposite to the connecting portion 13e, that is, the end toward the outside of the car 2, is not particularly fixed, and the free end 13f is not fixed. It is composed. Here, the normal time means that neither the pressurization nor the depressurization of the car 2 by the pressure control device having the intake blower 4a and the exhaust blower 4b described above is performed, and the pressure in the car 2 is adjusted. It means not in the state. For example, the state in which the car 2 reaches the desired floor where the hall call was made and stops, or the car 2 is moving up and down a relatively low level in the hoistway 21 corresponds to the normal time.
　可撓性部材１３は、例えば天然ゴム或いは合成ゴムなどにより成型されるもので、上部水平材１３ａ、この上部水平部１３ａと上部薄板材１３ｂ（第１の平板状部）とを連結する垂直材１３ｄ、上部薄板材１３ｂ（第１の平板状部）、この上部薄板材１３ｂ（第１の平板状部）が折り返される連結部１３ｅ、及び下部薄板材１３ｃ（第２の平板状部）は一体構造となっている。上部薄板材１３ｂ（第１の平板状部）及び下部薄板材１３ｃ（第２の平板状部）は、気圧制御装置による乗りかご２内の加圧及び減圧に応じて支障なく弾性変形可能な厚さ寸法に設定されている。一方、上部水平部１３ａと垂直材１３ｄは、必要な取り付け強度を確保するため、上部薄板材１３ｂ（第１の平板状部）及び下部薄板材１３ｃ（第２の平板状部）より厚さ寸法が大きく設定されている。なお、本実施例では、可撓性部材１３を天然ゴム或いは合成ゴムにて成型したものとしているが、これに限定するものではなく他の可撓性の材料で可撓性部材１３を構成することもできる。例えば、樹脂或いは薄板状の金属部材、例えば、０.２ｍｍ厚のステンレス鋼などでも良い。 The flexible member 13 is formed of, for example, natural rubber or synthetic rubber, and is an upper horizontal member 13a, and a vertical member that connects the upper horizontal portion 13a and the upper thin plate member 13b (first flat plate portion). 13d, the upper thin plate member 13b (first flat plate portion), the connecting portion 13e where the upper thin plate member 13b (first flat plate portion) is folded, and the lower thin plate member 13c (second flat plate portion) are integrated. It has a structure. The upper thin plate member 13b (first flat plate portion) and the lower thin plate member 13c (second flat plate portion) have a thickness that can be elastically deformed without hindrance according to the pressurization and depressurization in the car 2 by the atmospheric pressure control device. The dimension is set. On the other hand, the upper horizontal portion 13a and the vertical member 13d are thicker than the upper thin plate material 13b (first flat plate portion) and the lower thin plate material 13c (second flat plate portion) in order to ensure the necessary mounting strength. Is set larger. In this embodiment, the flexible member 13 is molded from natural rubber or synthetic rubber. However, the present invention is not limited to this, and the flexible member 13 is composed of other flexible materials. You can also For example, resin or a thin metal member, for example, stainless steel having a thickness of 0.2 mm may be used.
　また、図４に示すように、ブラケット１４の水平片１４ａと可動押さえ具１６の水平片１６ｂとの間には所定の間隙が確保され、可動押さえ具１６の長穴１６ａを介し、可動押さえ具１６の高さ位置を調整することにより、可撓性部材１３の下部薄板材１３ｃ（第２の平板状部）とかごシル７間に存在する通常時における間隙１１ａの高さ寸法を最適なものに調整可能としている。例えば、長穴１６ａの外径(直径)をＤ１、ロッド材１５の外径(直径)をＤ２としたとき、Ｄ１及びＤ２の関係は、１.４３≦Ｄ１／Ｄ２≦２.４０の範囲とするのが好ましく、Ｄ１／Ｄ２＝２.００とするのが望ましい。これにより（Ｄ１－Ｄ２）分だけブラケット１４の水平片１４ａを上下動させることができ、可撓性部材１３を構成する下部薄板材１３ｃ（第２の平板状部）とかごシル７との間隙１１ａを調整することが可能となる。 As shown in FIG. 4, a predetermined gap is secured between the horizontal piece 14 a of the bracket 14 and the horizontal piece 16 b of the movable presser 16, and the movable presser 16 is inserted through the elongated hole 16 a of the movable presser 16. By adjusting the height position of 16, the height dimension of the gap 11 a in the normal state existing between the lower thin plate material 13 c (second flat plate portion) of the flexible member 13 and the car sill 7 is optimized. Can be adjusted. For example, when the outer diameter (diameter) of the long hole 16a is D1 and the outer diameter (diameter) of the rod member 15 is D2, the relationship between D1 and D2 is the range of 1.43 ≦ D1 / D2 ≦ 2.40. It is preferable to set D1 / D2 = 2.00. As a result, the horizontal piece 14a of the bracket 14 can be moved up and down by (D1-D2), and the gap between the lower thin plate material 13c (second flat plate portion) constituting the flexible member 13 and the car sill 7 is increased. 11a can be adjusted.
　この状態で気圧制御装置によって乗りかご２内の気圧制御が行われた場合、上述した気密構造は次のように作用する。　
　図５は、図３におけるかご戸下部の拡大図であって、乗りかご内加圧時の拡大図である。　
　乗りかご２内を加圧すると、可撓性部材１３の下部薄板材１３ｃ（第２の平板状部）とかごシル７間の間隙１１ａにあっては、乗りかご２内から外側に向かって空気が通過し、流速により減圧される。この減圧及び上部薄板材１３ｂ（第１の平板状部）とブラケット１４の水平片１４ａ間に存在するくさび状の間隙１９に掛かる風圧により、まず上部薄板材１３ｂ（第１の平板状部）と下部薄板材１３ｃ（第２の平板状部）の連結部１３ｅが押し下げられてかごシル７に当接する。この連結部１３ｅのかごシル７への当接により間隙１１ａが塞がれて空気の流れが止まった後は、乗りかご２内と外側の差圧により、上部薄板材１３ｂ（第１の平板状部）の上面に圧力が掛かり、連結部１３ｅはさらにかごシル７に押し付けられ、確実に気密性が保持される。 When the atmospheric pressure control in the car 2 is performed by the atmospheric pressure control device in this state, the above-described airtight structure acts as follows.
FIG. 5 is an enlarged view of the lower part of the car door in FIG. 3 and is an enlarged view at the time of pressurization in the car.
When the inside of the car 2 is pressurized, in the gap 11a between the lower thin plate member 13c (second flat plate portion) of the flexible member 13 and the car sill 7, air flows from the inside of the car 2 toward the outside. Passes and is depressurized by the flow rate. Due to this reduced pressure and the wind pressure applied to the wedge-shaped gap 19 existing between the upper thin plate member 13b (first flat plate portion) and the horizontal piece 14a of the bracket 14, first, the upper thin plate member 13b (first flat plate portion) The connecting portion 13e of the lower thin plate member 13c (second flat plate-like portion) is pushed down and comes into contact with the car sill 7. After the gap 11a is blocked by the contact of the connecting portion 13e with the car sill 7 and the air flow is stopped, the upper thin plate member 13b (first flat plate shape) is caused by the differential pressure between the inside and the outside of the car 2. The pressure is applied to the upper surface of the part), and the connecting part 13e is further pressed against the car sill 7, so that the airtightness is reliably maintained.
　図６は、図３におけるかご戸下部の拡大図であって、乗りかご内減圧時の拡大図である。　
　乗りかご２内を減圧すると、可撓性部材１３の下部薄板材１３ｃ（第２の平板状部）とかごシル７間の間隙１１ａにあっては、外側から乗りかご２内に向かって空気が通過し、流速により減圧される。この減圧及び上部薄板材１３ｂ（第１の平板状部）と下部薄板材１３ｃ（第２の平板状部）間に存在するくさび状の間隙２０に掛かる風圧により、まず下部薄板材１３ｃ（第２の平板状部）の自由端１３ｆが押し下げられてかごシル７に当接する。この自由端１３ｆのかごシル７への当接により間隙１１ａが塞がれて空気の流れが止まった後は、乗りかご２内と外側の差圧により、下部薄板材１３ｃ（第２の平板状部）の上面及び上部薄板材１３ｂ（第１の平板状部）の下面に圧力が掛かり、自由端１３ｆはさらにかごシル７に押し付けられ、確実に気密性が保持される。このとき、図６では、上部薄板材１３ｂ（第１の平板状部）の上面がブラケット１４の水平片１４ａの下面に当接する状態を示しているが、必ずしもこれに限られるものではない。すなわち、上部薄板材１３ｂ（第１の平板状部）の上面とブラケット１４の水平片１４ａの下面との間に僅かに間隙が形成されても良い。　
　なお、図５又は図６に示した乗りかご２内の加圧又は乗りかご２内の減圧は、例えば、吸気ブロア４ａ及び排気ブロア４ｂを有する気圧制御装置により、乗りかご２内を数ｈＰａずつ段階的にステップ状に乗りかご２の高さに応じて変化させるものである。 FIG. 6 is an enlarged view of the lower part of the car door in FIG. 3 and is an enlarged view at the time of depressurization in the car.
When the inside of the car 2 is depressurized, in the gap 11 a between the lower thin plate member 13 c (second flat plate portion) of the flexible member 13 and the car sill 7, air flows from the outside toward the car 2. Passes and is depressurized by the flow rate. Due to this reduced pressure and the wind pressure applied to the wedge-shaped gap 20 existing between the upper thin plate member 13b (first flat plate portion) and the lower thin plate member 13c (second flat plate portion), the lower thin plate member 13c (second The free end 13f of the flat plate-shaped part) is pushed down and comes into contact with the car sill 7. After the gap 11a is blocked by the contact of the free end 13f with the car sill 7 and the air flow is stopped, the lower thin plate 13c (second flat plate shape) is caused by the differential pressure between the inside and outside of the car 2. Part) and the lower surface of the upper thin plate member 13b (first flat plate part) are pressed, and the free end 13f is further pressed against the car sill 7 so that the airtightness is reliably maintained. At this time, FIG. 6 shows a state in which the upper surface of the upper thin plate member 13b (first flat plate portion) is in contact with the lower surface of the horizontal piece 14a of the bracket 14, but this is not necessarily limited thereto. That is, a slight gap may be formed between the upper surface of the upper thin plate member 13 b (first flat plate-like portion) and the lower surface of the horizontal piece 14 a of the bracket 14.
The pressurization in the car 2 or the pressure reduction in the car 2 shown in FIG. 5 or 6 is performed, for example, by several hPa in the car 2 by an atmospheric pressure control device having an intake blower 4a and an exhaust blower 4b. In stepwise fashion, it is changed according to the height of the car 2.

The air passes from the inside of the car 2 to the outside through the gap, and is depressurized by the flow velocity at that time. Due to the reduced pressure and the wind pressure applied to the wedge-shaped gap 19 existing between the upper thin plate member 33b (first flat plate portion) and the horizontal member 33a, the upper thin plate member 33b (first flat plate portion) and the lower thin plate member 33c. The connecting portion 33 d of the (second flat plate-like portion) is pushed down and comes into contact with the car sill 7. The contact of the connecting portion 33d with the car sill 7 closes the substantially horizontal gap that has existed between the lower thin plate member 33c (second flat plate-like part) and the car sill 7 until then, and the car 2 The air flow flowing from the inside to the outside stops, and a differential pressure is generated between the inside and outside of the car 2. Due to this differential pressure, pressure is applied to the upper surface of the upper thin plate member 33b (first flat plate-like portion), and the connecting portion 33d is further pressed against the car sill 7 so that the airtightness is reliably maintained.
　他方、気圧制御装置により、乗りかご２内が減圧されると、可撓性部材３３の下部薄板材３３ｃ（第２の平板状部）とかごシル７間に存在する間隙を介して、空気が外側から乗りかご２内へ向かって通過し、そのときの流速により減圧される。この減圧及び上部薄板材３３ｂ（第１の平板状部）と下部薄板材３３ｃ（第２の平板状部）間に存在するくさび状の間隙２０に掛かる風圧により、下部薄板材３３ｃ（第２の平板状部）の自由端３３ｅが押し下げられてかごシル７に当接する。この自由端３３ｅのかごシル７への当接により、それまで下部薄板材３３ｃ（第２の平板状部）とかごシル７間に存在していた略水平の間隙は塞がれ、外側から乗りかご２内へと流れる空気流は止まり、乗りかご２内と外側との間に差圧が生じる。この差圧により上部薄板材３３ｂ（第１の平板状部）の下面及び下部薄板材３３ｃ（第２の平板状部）の上面に圧力が掛かり、自由端３３ｅはさらにかごシル７に押し付けられ、確実に気密性が保持される。 On the other hand, when the inside of the car 2 is depressurized by the atmospheric pressure control device, the air is passed through the gap between the lower thin plate member 33c (second flat plate portion) of the flexible member 33 and the car sill 7. The vehicle passes from the outside toward the inside of the car 2 and is depressurized by the flow velocity at that time. Due to the reduced pressure and the wind pressure applied to the wedge-shaped gap 20 existing between the upper thin plate member 33b (first flat plate portion) and the lower thin plate member 33c (second flat plate portion), the lower thin plate member 33c (second flat plate member 33c (second flat plate portion)) is provided. The free end 33e of the flat plate portion is pushed down and comes into contact with the car sill 7. Due to the contact of the free end 33e with the car sill 7, the substantially horizontal gap that has existed between the lower thin plate member 33c (second flat plate-like part) and the car sill 7 until then is closed, and the car slid from the outside. The air flow flowing into the car 2 stops and a differential pressure is generated between the inside and outside of the car 2. Due to this differential pressure, pressure is applied to the lower surface of the upper thin plate member 33b (first flat plate portion) and the upper surface of the lower thin plate member 33c (second flat plate portion), and the free end 33e is further pressed against the car sill 7. Airtightness is reliably maintained.
　図８は、図７に示すかご戸下部の変形例を示す拡大図である。図８に示すように、可撓性部材３３は、ブラケット１４の水平片１４ａの下面に当接する上部水平材３３ａ、少なくとも通常時に上部水平材３３ａとの間にくさび状の間隙２０を有して配される上部薄板材３３ｂ（第１の平板状部）、上部薄板材３３ｂ（第１の平板状部）の一端から延設されると共に、少なくとも通常時に上部薄板材３３ｂ（第１の平板状部）との間にくさび状の間隙１９を有し、かつ通常時にかごシル７との間に略水平の間隙を有して配置される下部薄板材３３ｃ（第２の平板状部）とを備える。換言すれば、可撓性部材３３は、少なくとも縦断面形状が乗りかご２の内側から外側へと向かい下方へ傾斜する上部薄板材３３ｂ（第１の平板状部）と、上部薄板材３３ｂ（第１の平板状部）の乗りかご２の外側端部である連結部３３ｄにて折り返され、乗りかご２の内側へと向かう下部薄板材３３ｃ（第２の平板状部）を備える。なお、下部薄板材３３ｃ（第２の平板状部）の連結部３３ｄと反対側の端部は、特に固定されることなく自由端３３ｅを構成している。 FIG. 8 is an enlarged view showing a modification of the lower part of the car door shown in FIG. As shown in FIG. 8, the flexible member 33 has a wedge-shaped gap 20 between the upper horizontal member 33a that contacts the lower surface of the horizontal piece 14a of the bracket 14 and at least the upper horizontal member 33a at normal times. The upper thin plate member 33b (first flat plate portion) and the upper thin plate member 33b (first flat plate portion) are extended from one end of the upper thin plate member 33b (first flat plate portion), and at least normally the upper thin plate member 33b (first flat plate portion). A lower thin plate member 33c (second flat plate portion) that has a wedge-shaped gap 19 between the lower plate member and the cage sill 7 at a normal time. Prepare. In other words, the flexible member 33 includes at least an upper thin plate member 33b (first flat plate portion) whose vertical cross-sectional shape is inclined downward from the inside to the outside of the car 2, and an upper thin plate member 33b (first plate member). 1), a lower thin plate member 33c (second flat plate portion) that is folded back at a connecting portion 33d that is an outer end portion of the car 2 and goes toward the inside of the car 2. In addition, the edge part on the opposite side to the connection part 33d of the lower thin-plate material 33c (2nd flat plate-shaped part) comprises the free end 33e, without being specifically fixed.
　図８に示すように、上部水平材３３ａの乗りかご２の外側の端部から所定の幅の領域は、断面コ字状部材３６の下側の水平片の上面とブラケット１４の水平片１４ａの下面との間に挟み込まれると共に、断面コ字状部材３６の上側の水平片の下面はブラケット１４の水平片１４ａの上面に当接する。また、ブラケット１４の水平片１４ａの上面には、ボルト３８により水平片１４ａの上面に固定或いは締結されるジャッキボルト３７が設けられている。ジャッキボルト３７は、ねじにより断面コ字状部材３６の上側の水平片の上面を押圧する。このようにジャッキボルト３７による押圧力により、上部水平材３３ａ及びブラケット１４の水平片１４ａと嵌合する断面コ字状部材３６は、上部水平材３３ａをブラケット１４の水平片１４ａに挟持する。図８に示す気密装置１２は、上述の可撓性部材３３、ブラケット１４、断面コ字状部材３６、ジャッキボルト３７、及びボルト３８のみにより構成される。よって、上述の図７の構成の場合と同様に、実施例１に示した気密装置より簡易な構成を実現できる。 As shown in FIG. 8, the region of a predetermined width from the outer end of the car 2 of the upper horizontal member 33 a is the upper surface of the horizontal piece below the U-shaped member 36 and the horizontal piece 14 a of the bracket 14. The lower surface of the upper horizontal piece of the U-shaped cross-section member 36 is in contact with the upper surface of the horizontal piece 14 a of the bracket 14. Further, on the upper surface of the horizontal piece 14 a of the bracket 14, a jack bolt 37 fixed or fastened to the upper surface of the horizontal piece 14 a by a bolt 38 is provided. The jack bolt 37 presses the upper surface of the horizontal piece on the upper side of the U-shaped member 36 with a screw. Thus, the U-shaped cross-section member 36 fitted to the upper horizontal member 33 a and the horizontal piece 14 a of the bracket 14 holds the upper horizontal member 33 a between the horizontal piece 14 a of the bracket 14 by the pressing force of the jack bolt 37. The hermetic device 12 shown in FIG. 8 includes only the flexible member 33, the bracket 14, the U-shaped member 36, the jack bolt 37, and the bolt 38 described above. Therefore, as in the case of the configuration of FIG. 7 described above, a simpler configuration than the airtight device shown in the first embodiment can be realized.
　次に、図８に示す通常時の状態から気圧制御装置により、乗りかご２内が加圧又は減圧される場合の気密装置１２の動作について説明する。　
　気圧制御装置により、乗りかご２内が加圧されると、可撓性部材３３の下部薄板材３３ｃ（第２の平板状部）とかごシル７間に存在する間隙を介して、空気が乗りかご２内から外側へ向かって通過し、そのときの流速により減圧される。この減圧及び上部薄板材３３ｂ（第１の平板状部）と下部薄板材３３ｃ（第２の平板状部）間に存在するくさび状の間隙１９に掛かる風圧により、下部薄板材３３ｃ（第２の平板状部）の自由端３３ｅが押し下げられてかごシル７に当接する。この自由端３３ｅのかごシル７への当接により、それまで下部薄板材３３ｃ（第２の平板状部）とかごシル７間に存在していた略水平の間隙は塞がれ、乗りかご２内から外側へと流れる空気流は止まり、乗りかご２と外側との間に差圧が生じる。この差圧により下部薄板材３３ｃ（第２の平板状部）の上面に圧力が掛かり、自由端３３ｅはさらにかごシル７に押し付けられ、確実に気密性が保持される。 Next, the operation of the airtight device 12 when the inside of the car 2 is pressurized or depressurized by the atmospheric pressure control device from the normal state shown in FIG. 8 will be described.
When the inside of the car 2 is pressurized by the atmospheric pressure control device, the air rides through a gap existing between the lower thin plate member 33c (second flat plate portion) of the flexible member 33 and the car sill 7. Passing from the inside of the car 2 to the outside, the pressure is reduced by the flow rate at that time. Due to this reduced pressure and the wind pressure applied to the wedge-shaped gap 19 existing between the upper thin plate material 33b (first flat plate portion) and the lower thin plate material 33c (second flat plate portion), the lower thin plate material 33c (second flat plate material 33c The free end 33e of the flat plate portion is pushed down and comes into contact with the car sill 7. Due to the contact of the free end 33e with the car sill 7, the substantially horizontal gap that has existed between the lower thin plate member 33c (second flat plate portion) and the car sill 7 until then is closed, and the car 2 The air flow flowing from the inside to the outside stops, and a differential pressure is generated between the car 2 and the outside. Due to this differential pressure, pressure is applied to the upper surface of the lower thin plate member 33c (second flat plate-like portion), and the free end 33e is further pressed against the car sill 7, so that airtightness is reliably maintained.
　他方、気圧制御装置により、乗りかご２内が減圧されると、可撓性部材３３の下部薄板材３３ｃ（第２の平板状部）とかごシル７間に存在する間隙を介して、空気が外側から乗りかご２内へ向かって通過し、そのときの流速により減圧される。この減圧及び上部水平材３３ａと上部薄板材３３ｂ（第１の平板状部）間に存在するくさび状の間隙２０に掛かる風圧により、上部薄板材３３ｂ（第１の平板状部）と下部薄板材３３ｃ（第２の平板状部）の連結部３３ｄが押し下げられてかごシル７に当接する。この連結部３３ｄのかごシル７への当接により、それまで下部薄板材３３ｃ（第２の平板状部）とかごシル７間に存在していた略水平の間隙は塞がれ、外側から乗りかご２内へと流れる空気流は止まり、乗りかご２内と外側との間に差圧が生じる。この差圧により上部薄板材３３ｂ（第１の平板状部）の上面に圧力が掛かり、連結部３３ｄはさらにかごシル７に押し付けられ、確実に気密性が保持される。 On the other hand, when the inside of the car 2 is depressurized by the atmospheric pressure control device, the air is passed through the gap between the lower thin plate member 33c (second flat plate portion) of the flexible member 33 and the car sill 7. The vehicle passes from the outside toward the inside of the car 2 and is depressurized by the flow velocity at that time. Due to the reduced pressure and the wind pressure applied to the wedge-shaped gap 20 existing between the upper horizontal member 33a and the upper thin plate member 33b (first flat plate portion), the upper thin plate member 33b (first flat plate portion) and the lower thin plate member. The connecting portion 33 d of 33 c (second flat plate-like portion) is pushed down and comes into contact with the car sill 7. The contact of the connecting portion 33d with the car sill 7 closes the substantially horizontal gap that has existed between the lower thin plate member 33c (second flat plate-like part) and the car sill 7 until then. The air flow flowing into the car 2 stops and a differential pressure is generated between the inside and outside of the car 2. Due to this differential pressure, pressure is applied to the upper surface of the upper thin plate member 33b (first flat plate-like portion), and the connecting portion 33d is further pressed against the car sill 7 so that the airtightness is reliably maintained.
　上述の通り、本実施例によれば、乗りかご２内の気圧変動に対し応答性良く乗りかご２内の密閉性を確保し得ると共に簡易な構成にて実現可能とするエレベータ装置を提供することができる。　
　また、本実施例によれば、上述の実施例１におけるような、可撓性部材３３を構成する下部薄板材３３ｃ（第２の平板状部）とかごシル７との間隙を調整することはできないものの、可撓性部材３３を構成する上部水平材３３ａ、上部薄板材３３ｂ（第１の平板状部）、及び下部薄板材３３ｃ（第２の平板状部）の厚さは略同一であることから、実施例１に比較し可撓性部材３３の成型がより容易となる。　
　また、本実施例では、気密装置１２を、可撓性部材３３、ブラケット１４，３４、及びボルト３５のみにより構成できることから、実施例１に比較し気密装置を更に簡易な構成にて実現できる。また、気密装置１２を、可撓性部材３３、ブラケット１４、断面コ字状部材３６、ジャッキボルト３７、及びボルト３８のみにより構成できることから、実施例１に比較し気密装置を更に簡易な構成にて実現することが可能となる。 As described above, according to this embodiment, it is possible to provide an elevator apparatus that can ensure airtightness in the car 2 with good responsiveness to atmospheric pressure fluctuations in the car 2 and can be realized with a simple configuration. Can do.
Further, according to the present embodiment, as in the above-described first embodiment, adjusting the gap between the lower thin plate material 33c (second flat plate portion) constituting the flexible member 33 and the car sill 7 is possible. Although not possible, the thicknesses of the upper horizontal member 33a, the upper thin plate member 33b (first flat plate portion), and the lower thin plate member 33c (second flat plate portion) constituting the flexible member 33 are substantially the same. Therefore, the flexible member 33 can be molded more easily than in the first embodiment.
Further, in the present embodiment, the airtight device 12 can be configured by only the flexible member 33, the brackets 14 and 34, and the bolts 35. Therefore, the airtight device can be realized with a simpler configuration as compared with the first embodiment. Further, since the airtight device 12 can be constituted by only the flexible member 33, the bracket 14, the U-shaped cross-section member 36, the jack bolt 37, and the bolt 38, the airtight device can be further simplified compared to the first embodiment. Can be realized.
　図９は、本発明の他の実施例に係る実施例３によるエレベータ装置の要部である乗りかごのかご戸下部の断面を示す拡大図であり、図１０は、図９に示すかご戸下部の変形例を示す拡大図である。本実施例では、可撓性部材を構成する下部薄板材（第２の平板状部）の自由端がかごシル側へと向かうよう傾斜させた点が実施例２と異なる。その他の構成は実施例２と同様であり、以下では実施例２と同様の構成要素に同一の符号を付し、実施例２と重複する説明を省略する。 9 is an enlarged view showing a cross section of a lower part of a car door of a car that is a main part of an elevator apparatus according to a third embodiment of the present invention, and FIG. 10 is a lower part of the car door shown in FIG. It is an enlarged view which shows the modified example. The present embodiment is different from the second embodiment in that the free end of the lower thin plate member (second flat plate portion) constituting the flexible member is inclined toward the car sill side. Other configurations are the same as those in the second embodiment. In the following, the same components as those in the second embodiment are denoted by the same reference numerals, and the description overlapping with the second embodiment is omitted.
　図９に示すように、本実施例に係るエレベータ装置１は、かご戸３下部に可撓性部材３３を有する気密装置１２を備える。可撓性部材３３は、ブラケット１４の水平片１４ａの下面に当接する上部水平材３３ａ、少なくとも通常時に上部水平材３３ａとの間にくさび状の間隙１９を有して配される上部薄板材３３ｂ（第１の平板状部）、上部薄板材３３ｂ（第１の平板状部）の一端から延設されると共に、少なくとも通常時に上部薄板材３３ｂ（第１の平板状部）との間にくさび状の間隙２０を有して配される下部薄板材３３ｃ’（第２の平板状部）を備える。上記くさび状の間隙２０は、上記くさび状の間隙１９より大きい。すなわち、上部薄板材３３ｂ（第１の平板状部）と下部薄板材３３ｃ’（第２の平板状部）により成す角度（開き角）は、上部水平材３３ａと上部薄板材３３ｂ（第１の平板状部）との成す角度（開き角）よりも大きい。換言すれば、可撓性部材３３は、少なくとも通常時において、縦断面形状が乗りかご２の内側へと向かい下方へ傾斜する上部薄板材３３ｂ（第１の平板状部）と、上部薄板材３３ｂ（第１の平板状部）の乗りかご２の内側端部である連結部３３ｄにて折り返され、乗りかご２の外側へと向かい下方へ傾斜する下部薄板材３３ｃ’（第２の平板状部）を備える。下部薄板材３３ｃ’（第２の平板状部）の連結部３３ｄと反対側の端部である自由端３３ｅは、所定の間隙を有して、かごシル７の上面から離間している。 As shown in FIG. 9, the elevator apparatus 1 according to the present embodiment includes an airtight apparatus 12 having a flexible member 33 at the lower part of the car door 3. The flexible member 33 is an upper thin plate member 33b arranged with a wedge-shaped gap 19 between the upper horizontal member 33a contacting the lower surface of the horizontal piece 14a of the bracket 14 and at least the upper horizontal member 33a at normal times. (First flat plate portion) and a wedge extending between one end of the upper thin plate member 33b (first flat plate portion) and at least normally the upper thin plate member 33b (first flat plate portion). The lower thin plate member 33c ′ (second flat plate-like portion) disposed with a gap 20 is provided. The wedge-shaped gap 20 is larger than the wedge-shaped gap 19. That is, the angle (open angle) formed by the upper thin plate member 33b (first flat plate portion) and the lower thin plate member 33c ′ (second flat plate portion) is the upper horizontal member 33a and the upper thin plate member 33b (first flat plate portion). It is larger than the angle (opening angle) formed with the flat plate portion. In other words, the flexible member 33 includes an upper thin plate member 33b (first flat plate portion) whose vertical cross-sectional shape is inclined downward toward the inside of the car 2, and an upper thin plate member 33b, at least normally. The lower thin plate member 33c ′ (second flat plate portion) which is folded back at the connecting portion 33d which is the inner end portion of the car 2 of the (first flat plate portion) and is inclined downward toward the outside of the car 2. ). A free end 33e, which is an end of the lower thin plate member 33c '(second flat plate-like portion) opposite to the connecting portion 33d, is spaced from the upper surface of the car sill 7 with a predetermined gap.
　可撓性部材３３は、例えば、天然ゴム、合成ゴムの他、樹脂或いは薄板状の金属部材、例えば、０.２ｍｍ厚のステンレス鋼などにより成型されている。そして、上部水平材３３ａ、上部薄板材３３ｂ（第１の平板状部）、この上部薄板材３３ｂ（第１の平板状部）が折り返される連結部３３ｄ、及び下部薄板材３３ｃ’（第２の平板状部）は一体構造となっている。図９に示すように、これら、上部水平材３３ａ、上部薄板材３３ｂ（第１の平板状部）、及び下部薄板材３３ｃ’（第２の平板状部）の厚さは略同一であり、上部薄板材３３ｂ（第１の平板状部）及び下部薄板材３３ｃ（第２の平板状部）が、気圧制御装置による乗りかご２内の加圧及び減圧に応じて支障なく弾性変形可能な厚さ寸法に設定されている。 The flexible member 33 is formed of, for example, natural rubber or synthetic rubber, resin, or a thin metal member, for example, 0.2 mm-thick stainless steel. The upper horizontal member 33a, the upper thin plate member 33b (first flat plate portion), the connecting portion 33d where the upper thin plate member 33b (first flat plate portion) is folded, and the lower thin plate member 33c ′ (second plate member). The flat plate portion has an integral structure. As shown in FIG. 9, the thicknesses of the upper horizontal member 33a, the upper thin plate member 33b (first flat plate portion), and the lower thin plate member 33c ′ (second flat plate portion) are substantially the same. Thickness that allows the upper thin plate member 33b (first flat plate portion) and the lower thin plate member 33c (second flat plate portion) to be elastically deformed without hindrance according to the pressurization and depressurization in the car 2 by the atmospheric pressure control device. The dimension is set.
　また、ブラケット１４の水平片１４ａへの可撓性部材３３の固定は、上述の実施例２と同様に、Ｌ字状の断面形状を有するブラケット３４及びボルト３５により実現される。本実施例における気密装置１２は、実施例２と同様に、可撓性部材３３、ブラケット１４，３４、及びボルト３５のみにより構成されるため、上述の実施例１に示した気密装置より簡易な構成を実現できる。また、実施例２と同様に、意匠性などを考慮し、ブラケット３４のうちパネル材３ａに対向する部分及びボルト３５を覆うよう化粧板などを取り付けることが好ましい。　
　なお、上述の通り本実施例における可撓性部材３３は、上部薄板材３３ｂ（第１の平板状部）と下部薄板材３３ｃ’（第２の平板状部）により成す角度（開き角）が、上部水平材３３ａと上部薄板材３３ｂ（第１の平板状部）との成す角度（開き角）よりも大きくなるよう構成されることから、特に、気圧制御装置による乗りかご２内の減圧時において、実施例２の構成に比較し更に応答性を向上させることが可能となる。すなわち、上部薄板材３３ｂ（第１の平板状部）と下部薄板材３３ｃ’（第２の平板状部）間に存在するくさび状の間隙２０に掛かる風圧により、下部薄板材３３ｃ（第２の平板状部）の自由端３３ｅを、実施例２と比較しより効果的に押し下げ、かごシル７に当接させることが可能となる。 Further, the flexible member 33 is fixed to the horizontal piece 14a of the bracket 14 by the bracket 34 and the bolt 35 having an L-shaped cross-sectional shape as in the second embodiment. Since the airtight device 12 in this embodiment is composed of only the flexible member 33, the brackets 14 and 34, and the bolts 35 as in the second embodiment, it is simpler than the airtight device shown in the above-described first embodiment. The configuration can be realized. Similarly to the second embodiment, in consideration of design and the like, it is preferable to attach a decorative plate or the like so as to cover a portion of the bracket 34 facing the panel material 3a and the bolt 35.
As described above, the flexible member 33 in this embodiment has an angle (opening angle) formed by the upper thin plate member 33b (first flat plate portion) and the lower thin plate member 33c ′ (second flat plate portion). The upper horizontal member 33a and the upper thin plate member 33b (first flat plate portion) are configured to be larger than the angle (opening angle) formed by the upper horizontal member 33b. Therefore, the response can be further improved as compared with the configuration of the second embodiment. That is, the lower thin plate member 33c (second flat plate member 33c (second flat plate portion) and the lower thin plate member 33c ′ (second flat plate portion) are caused by the wind pressure applied to the wedge-shaped gap 20 existing between the upper thin plate member 33b (first flat plate portion) and the lower thin plate member 33c ′. The free end 33e of the flat plate portion can be more effectively pushed down and brought into contact with the car sill 7 as compared with the second embodiment.
　図１０は、図９に示すかご戸下部の変形例を示す拡大図である。図１０に示すように、可撓性部材３３は、ブラケット１４の水平片１４ａの下面に当接する上部水平材３３ａ、少なくとも通常時に上部水平材３３ａとの間にくさび状の間隙２０を有して配される上部薄板材３３ｂ（第１の平板状部）、上部薄板材３３ｂ（第１の平板状部）の一端から延設されると共に、少なくとも通常時に上部薄板材３３ｂ（第１の平板状部）との間にくさび状の間隙１９を有して配される下部薄板材３３ｃ’（第２の平板状部）を備える。上記くさび状の間隙１９は、上記くさび状の間隙２０より大きい。すなわち、上部薄板材３３ｂ（第１の平板状部）と下部薄板材３３ｃ’（第２の平板状部）により成す角度（開き角）は、上部水平材３３ａと上部薄板材３３ｂ（第１の平板状部）により成す角度（開き角）よりも大きい。換言すれば、可撓性部材３３は、少なくとも通常時において、縦断面形状が乗りかご２の内側から外側へと向かい下方へ傾斜する上部薄板材３３ｂ(第１の平板状部)と、上部薄板材３３ｂ(第１の平板状部)の乗りかご２の外側端部である連結部３３ｄにて折り返され、乗りかご２の内側へと向かい下方へ傾斜する下部薄板材３３ｃ’（第２の平板状部）を備える。下部薄板材３３ｃ’（第２の平板状部）の連結部３３ｄと反対側の端部である自由端３３ｅは、所定の間隙を有して、かごシル７の上面から離間している。 FIG. 10 is an enlarged view showing a modification of the lower part of the car door shown in FIG. As shown in FIG. 10, the flexible member 33 has a wedge-shaped gap 20 between the upper horizontal member 33a that contacts the lower surface of the horizontal piece 14a of the bracket 14 and at least the upper horizontal member 33a at normal times. The upper thin plate member 33b (first flat plate portion) and the upper thin plate member 33b (first flat plate portion) are extended from one end of the upper thin plate member 33b (first flat plate portion), and at least normally the upper thin plate member 33b (first flat plate portion). And a lower thin plate member 33c ′ (second flat plate portion) disposed with a wedge-shaped gap 19 between them. The wedge-shaped gap 19 is larger than the wedge-shaped gap 20. That is, the angle (open angle) formed by the upper thin plate member 33b (first flat plate portion) and the lower thin plate member 33c ′ (second flat plate portion) is the upper horizontal member 33a and the upper thin plate member 33b (first flat plate portion). It is larger than the angle (opening angle) formed by the flat plate portion. In other words, the flexible member 33 includes an upper thin plate member 33b (first flat plate-like portion) whose vertical cross-sectional shape is inclined downward from the inner side to the outer side of the car 2, at least normally, and an upper thin plate member. A lower thin plate member 33c ′ (second flat plate) which is folded back at a connecting portion 33d which is an outer end portion of the car 2 of the plate member 33b (first flat plate-like portion) and is inclined downward toward the inside of the car 2. Shaped part). A free end 33e, which is an end of the lower thin plate member 33c '(second flat plate-like portion) opposite to the connecting portion 33d, is spaced from the upper surface of the car sill 7 with a predetermined gap.
