Description

この発明は、エレベータ乗り場の出入口を開閉するエレベータの乗り場ドア装置に関する。   The present invention relates to an elevator landing door device that opens and closes an entrance of an elevator landing.

エレベータ乗り場の壁面には、乗りかごに対して乗降するための出入口が設けられ、この出入口にその開閉用のドア装置が据え付けられている。この種のドア装置の一例である片開き多段速式のドア装置の構造を図４に示してある。   On the wall surface of the elevator hall, an entrance for getting in and out of the car is provided, and a door device for opening and closing the door is installed at the entrance. FIG. 4 shows the structure of a single-open multi-speed door device which is an example of this type of door device.

図４に示すように、エレベータ乗り場１の出入口２には三方枠３が取り付けられ、この三方枠３の背面側に２枚のドアパネル４ａ，４ｂが互いに前後に位置をずらして配置されている。各ドアパネル４ａ，４ｂはその上部がハンガーレール（図示せず）に懸架されて左右方向に移動可能に支持されている。   As shown in FIG. 4, a three-way frame 3 is attached to the entrance 2 of the elevator hall 1, and two door panels 4 a and 4 b are arranged on the back side of the three-way frame 3 so as to be shifted from each other in the front-rear direction. The upper portions of the door panels 4a and 4b are suspended on hanger rails (not shown) and supported so as to be movable in the left-right direction.

図４の状態は、出入口２が両ドアパネル４ａ，４ｂにより閉鎖されている状態であり、これらドアパネル４ａ，４ｂの背面側の昇降路５内を乗りかご６が昇降移動する。そして乗りかご６がエレベータ乗り場１に着床して停止した際に、その乗りかご６のかごドア（図示せず）に駆動されて各ドアパネル４ａ，４ｂが図の左側の戸袋部９に向って移動し、その戸袋部９に収納されて出入口２が開放される。   4 is a state in which the doorway 2 is closed by both door panels 4a and 4b, and the car 6 moves up and down in the hoistway 5 on the back side of the door panels 4a and 4b. When the car 6 reaches the elevator hall 1 and stops, it is driven by a car door (not shown) of the car 6 so that the door panels 4a and 4b face the door pocket 9 on the left side of the figure. It moves, is accommodated in the door pocket part 9, and the entrance / exit 2 is opened.

この際、一方のドアパネル４ａは他方のドアパネル４ｂのほぼ２倍の速度で戸袋部９に向って移動し、これによりドアパネル４ａ，４ｂが戸袋部９内で互いに前後に重なるように収納される。   At this time, the one door panel 4a moves toward the door pocket 9 at a speed approximately twice that of the other door panel 4b, whereby the door panels 4a and 4b are accommodated in the door pocket 9 so as to overlap each other.

また、戸閉時には各ドアパネル４ａ，４ｂが戸袋部９の反対側の戸閉方向に向って移動する。この際にも、一方のドアパネル４ａは他方のドアパネル４ｂのほぼ２倍の速度で移動し、図４に示すように一方のドアパネル４ａと他方のドアパネル４ｂとが前後に段違い状に重なる状態となり、これにより出入口２が閉鎖される。   Further, when the door is closed, the door panels 4 a and 4 b move in the door closing direction on the opposite side of the door pocket 9. Also at this time, one door panel 4a moves at a speed almost twice that of the other door panel 4b, and as shown in FIG. 4, the one door panel 4a and the other door panel 4b overlap each other in a stepwise manner, Thereby, the entrance / exit 2 is closed.

ところで近年、火災発生時の遮煙の観点からドア装置の密閉性を高めることが重要な課題となっている。すなわち、ドア装置の密閉性が低いと、エレベータ乗り場で火災が発生した際に、その煙がドア装置を通してその背面側の昇降路内に流入し、その昇降路が煙を上昇させる煙突として働いて火勢を強めてしまう恐れがあり、このためドア装置の密閉性をできるだけ高め、高い遮煙性能が得られるようにすることが望まれている。   Incidentally, in recent years, it has become an important issue to improve the sealing performance of the door device from the viewpoint of smoke shielding in the event of a fire. That is, if the door device is not tightly sealed, when a fire occurs at the elevator hall, the smoke flows into the hoistway on the back side through the door device, and the hoistway works as a chimney that raises the smoke. There is a risk of increasing the fire power, and therefore it is desired to improve the sealing performance of the door device as much as possible and to obtain high smoke shielding performance.

そこで、図４に示すドア装置においては、三方枠３の戸当り側縁部における昇降路５側の背面部にゴム等の弾性体からなる受け用のパッキン１０を取り付け、また速い速度で移動する後側のドアパネル４ｂにおける戸当り側縁部の背面部にゴム等の弾性体からなる当り用のパッキン１１を取り付け、ドアパネル４ａ，４ｂの戸閉時にその当り用のパッキン１１を受け用のパッキン１０に当接させてドアパネル４ｂと三方枠の戸当り部との間の隙間を密閉し、ドア装置の遮煙性を高めるようにしている。   Therefore, in the door device shown in FIG. 4, a receiving packing 10 made of an elastic body such as rubber is attached to the back surface portion on the hoistway 5 side of the door-contacting side edge of the three-way frame 3 and moves at a high speed. A contact packing 11 made of an elastic material such as rubber is attached to the back of the door contact side edge of the rear door panel 4b, and the contact packing 11 is received when the door panels 4a and 4b are closed. To seal the gap between the door panel 4b and the door contact portion of the three-way frame, thereby improving the smoke-shielding property of the door device.

しかしながら、このように三方枠３の戸当り側縁部における昇降路５側の背面部とドアパネル４ｂにおける戸当り側縁部の背面部とにパッキン１０，１１を取り付け、これらパッキン１０，１１で戸当り間の隙間を密閉する構造では、乗りかご６のかごドアがガラス窓付きのものであるときに、その乗りかご６内から前記パッキン１０，１１が見えてしまい、このため外観が悪く、乗りかご６内の乗客に見苦しさを与えてしまう。   However, the packings 10 and 11 are attached to the back part of the doorway side edge of the door panel 4b and the packings 10 and 11 at the doorside side edge of the three-way frame 3 as described above. In the structure in which the clearance between the hits is sealed, when the car door of the car 6 has a glass window, the packings 10 and 11 can be seen from within the car 6, and thus the appearance is poor and the car has a bad appearance. The passenger in the car 6 is unsightly.

また、パッキン１０，１１は単なる一方向に長い中実の部材であり、このためドアパネル４ｂの左右方向の移動のストローク幅を厳格に調整しないとパッキン１０，１１の密着性が低下し、それゆえその調整が面倒となり、さらにまたドアパネル４ｂの立付けが悪いような場合にパッキン１０，１１との当接間の一部に隙間が生じ、遮煙性が低下するという問題が生じる。   Further, the packings 10 and 11 are simply solid members that are long in one direction. For this reason, unless the stroke width of the movement of the door panel 4b in the left-right direction is strictly adjusted, the adhesion of the packings 10 and 11 is lowered. When the adjustment is troublesome and the door panel 4b is not well installed, there is a problem that a gap is formed in a part between the contact with the packings 10 and 11 and the smoke shielding property is lowered.

この発明はこのような点に着目してなされたもので、その目的とするところは、良好な外観を保て、またドアパネルの移動に関する厳格な調整を要することなく、的確にドアパネルと三方枠の戸当り部との間の隙間を密閉して遮煙性を高めることができるエレベータの乗り場ドア装置を提供することにある。   The present invention has been made paying attention to such points, and the object of the present invention is to maintain a good appearance and to accurately adjust the door panel and the three-sided frame without requiring a strict adjustment regarding the movement of the door panel. An object of the present invention is to provide a landing door device for an elevator that can enhance a smoke shielding property by sealing a gap with a door stop.

この発明によれば、良好な外観を保て、またドアパネルの移動に関する厳格な調整を要することなく、的確にドアパネルと三方枠の戸当り部との間の隙間を密閉して遮煙性を高めることができる。   According to the present invention, it is possible to maintain a good appearance and to accurately seal the gap between the door panel and the three-way frame door stop portion without requiring a strict adjustment regarding the movement of the door panel, thereby improving the smoke shielding property. be able to.

以下、この発明の一実施形態について図１ないし図３を参照して説明する。なお、従来の構成と対応する部分には同一符号を付してその重複する説明を省略する。   Hereinafter, an embodiment of the present invention will be described with reference to FIGS. In addition, the same code | symbol is attached | subjected to the part corresponding to the conventional structure, and the duplicate description is abbreviate | omitted.

図１に示すように、三方枠３は、速い速度で移動するドアパネル４ａの戸当り側の端面４ａ１と対向する戸当り部３ａを有し、この戸当り部３ａに図２および図３に示すように金属製の支持板１４がねじ１５を介して取り付けられ、この支持板１４にゴム等の弾性体からなるパッキン１６が装着されている。 As shown in FIG. 1, the three-way frame 3 has a door contact portion 3a facing the door contact end surface 4a 1 of the door panel 4a that moves at a high speed. As shown, a metal support plate 14 is attached via screws 15, and a packing 16 made of an elastic body such as rubber is attached to the support plate 14.

前記支持板１４は、両側部に断面ほぼコ字状の嵌着部１７を有し、またパッキン１６は主部１８と基部１９とを一体的に有し、前記基部１９の両側部に舌片２０が形成されている。   The support plate 14 has fitting portions 17 having a substantially U-shaped cross section on both sides, and the packing 16 has a main portion 18 and a base portion 19 integrally, and tongue pieces on both sides of the base portion 19. 20 is formed.

そしてパッキン１６は、前記舌片２０を支持板１４の嵌着部１７に圧入して嵌着することにより、主部１８がドアパネル４ａの戸当り側の端面４ａ１に対向するように支持板１４に取り付けられている。 The gasket 16, the by fitting press-fitted to the fitting portion 17 of the tongues 20 the support plate 14, the main portion 18 is a support plate 14 so as to face the end surface 4a 1 of the doorstop side door panel 4a Is attached to.

パッキン１６はドアパネル４ａの縦の長さ寸法とほぼ同じ長さの寸法を有している。そしてこのパッキン１６の主部１８は、やや扁平な中空状をなし、ドアパネル４ａと対向する面の断面は、ドアパネル４ａに向って円弧状に膨らみ出る曲面となっている。   The packing 16 has a length that is substantially the same as the vertical length of the door panel 4a. The main portion 18 of the packing 16 has a slightly flat hollow shape, and the cross section of the surface facing the door panel 4a is a curved surface that swells in an arc shape toward the door panel 4a.

出入口２の閉鎖時には、一方のドアパネル４ａが速い速度で、他方のドアパネル４ｂが遅い速度でそれぞれ戸閉方向に向って移動する。そして一方のドアパネル４ａの戸当り側の端面４ａ１がパッキン１６の主部１８に当接し、他方のドアパネル４ｂが一方のドアパネル４ａに対して段違い状に配置し、この状態でドアパネル４ａ，４ｂが停止して出入口２が閉鎖される。 When the doorway 2 is closed, one door panel 4a moves at a high speed and the other door panel 4b moves at a low speed toward the door closing direction. The door end face 4a1 of one door panel 4a contacts the main portion 18 of the packing 16, and the other door panel 4b is arranged in a stepped manner with respect to the one door panel 4a. In this state, the door panels 4a, 4b Stop and the doorway 2 is closed.

ドアパネル４ａがパッキン１６の主部１８に当接した際には、その中空状の主部１８が弾性的に潰れるように変形し、この変形でパッキン１６の主部１８とドアパネル４ａの戸当り側の端面４ａ１とが密着し、この密着でドアパネル４ａと三方枠３の戸当り部３ａとの間の隙間が密閉され、したがってエレベータ乗り場１側で火災が発生したときに、その煙がドアパネル４ａと三方枠３の戸当り部３ａとの間から昇降路内に流入するようなことがなく、これにより遮煙性を高めることができる。 When the door panel 4a comes into contact with the main portion 18 of the packing 16, the hollow main portion 18 is deformed so as to be elastically crushed, and this deformation causes the main portion 18 of the packing 16 and the door-to-door side of the door panel 4a. end surface 4a 1 and is in close contact, the gap between the doorstop portion 3a of the door panels 4a and jamb 3 in this adhesion is sealed, thus when a fire occurs in the elevator hall 1 side, its smoke door panels 4a And the door-to-door part 3a of the three-way frame 3 does not flow into the hoistway, thereby improving the smoke shielding property.

パッキン１６は、出入口２の閉鎖時に、ドアパネル４ａの端面４ａ１と三方枠３の戸当り部３ａとの間に挟まれており、このため昇降路５内を昇降する乗りかご６のかごドアがガラス窓付きのものであっても、前記パッキン１６を乗りかご６内からは見えず、したがって外観が良好に保たれ、乗りかご６内の乗客に見苦しさを与えるようなことがない。 Packing 16, upon closure of the entrance 2 is sandwiched between the end face 4a 1 and jamb 3 of doorstop portion 3a of the door panels 4a, car door of the car 6 to lift the order hoistway 5 Even with a glass window, the packing 16 cannot be seen from the inside of the car 6, so that the appearance is kept good and the passengers in the car 6 are not unsightly.

パッキン１６の主部１８は、中空状で、その表面が円弧状に膨らみ出る曲面であることからドアパネル４ａが当接した際に的確に弾性的に変形してドアパネル４ａの端面４ａ１と密着する。 Main portion 18 of the packing 16 is a hollow, the surface door panels 4a because it is curved out bulge in an arc shape in close contact with the end face 4a 1 of the door panels 4a and accurately elastically deformed when in contact with .

また、パッキン１６の主部１８が中空状でその弾性的な変形度合が大きいことから、ドアパネル４ａの移動ストロークにある程度のばらつきがあっても、そのばらつきを主部１８の弾性的な変形で吸収することができ、したがってドアパネル４ａの移動ストロークに関する厳格な調整が不要となり、調整の作業が容易となる。さらに、ドアパネル４ａの立て付けが悪く、三方枠３の戸当り部３ａに対してドアパネル４ａの戸当り側の端面４ａ１が傾くような場合で合っても、その傾きを主部１８の弾性的な変形で吸収して的確にドアパネル４ａの端面４ａ１と三方枠３の戸当り部３ａとの間の隙間を密閉することができる。 Further, since the main portion 18 of the packing 16 is hollow and its elastic deformation degree is large, even if there is some variation in the movement stroke of the door panel 4a, the variation is absorbed by the elastic deformation of the main portion 18. Therefore, a strict adjustment regarding the moving stroke of the door panel 4a is not required, and the adjustment work is facilitated. Furthermore, Tatetsuke door panel 4a is poor, even if such end surface 4a 1 of the doorstop side of the door panel 4a is inclined relative to the doorstop portion 3a of the jamb 3, elastic main portion 18 and the inclination it is possible to seal the gap between the accurately doorstop portion 3a of the end surface 4a 1 and jamb 3 of the door panel 4a absorbs at Do deformation.
