Description

本発明は、エレベータの出入口を開閉するドアの下端と敷居との隙間を閉塞する遮煙材が、ドアの下端に設置されたエレベータドア装置に関するものである。   The present invention relates to an elevator door device in which a smoke shielding material that closes a gap between a lower end of a door that opens and closes an entrance of an elevator and a sill is installed at the lower end of the door.

従来のエレベータドア装置を図７〜図１０により説明する。図７はエレベータの乗場ドア装置を昇降路側から見た図、図８は図７のII―II線に沿う断面図で、両図ともドア下部の一部を断面で示している。図９は図７の乗場ドアの全開状態における戸開側端部付近を示す図、図１０は図９の右側面図である。   A conventional elevator door apparatus will be described with reference to FIGS. FIG. 7 is a view of the elevator landing door device as seen from the hoistway side, and FIG. 8 is a cross-sectional view taken along the line II-II in FIG. FIG. 9 is a view showing the vicinity of the door opening side end portion of the landing door of FIG. 7, and FIG. 10 is a right side view of FIG.

図において、１，１は乗場出入口を開閉する一対の乗場ドア、３はドアハンガー４によって乗場ドア１の上部に取り付けられたローラであり、建築壁６に固定されたケース８に取り付けられたレール９に沿って乗場ドア１を開閉する。１０は出入口の両側部及び上部を構成する三方枠、１１は出入口下部の床に取り付けられた敷居、１１ａは敷居溝、１ａ，１ｂは乗場ドア１を構成している表面板及び裏面板であり、表面板１ａの下部には敷居溝１１ａに挿入された乗場ドア１の開閉を案内する複数のドアガイドシュー１３が設けられている。１４はボルト及びピン等の固定用部材１６によって表面板１ａの下部に設けられた遮煙材であり、難燃性の弾性材で構成され、乗場ドア１の開閉に伴って敷居１１上面を摺動する。１４ａは乗場ドア１の戸開側端部に配置された戸開側遮煙材である。これらのドアガイドシュー１３，遮煙材１４，１４ａによって、乗場ドア１の下端と敷居１１の上面との隙間を閉塞している。   In the figure, 1 and 1 are a pair of landing doors that open and close the landing doorway, 3 is a roller attached to the top of the landing door 1 by a door hanger 4, and a rail attached to a case 8 fixed to the building wall 6 The landing door 1 is opened and closed along the line 9. 10 is a three-sided frame that forms both sides and upper part of the entrance, 11 is a sill attached to the floor below the entrance, 11a is a sill groove, 1a and 1b are front and back plates constituting the landing door 1 A plurality of door guide shoes 13 for guiding the opening and closing of the landing door 1 inserted in the sill groove 11a are provided below the surface plate 1a. Reference numeral 14 denotes a smoke shielding material provided at the lower portion of the surface plate 1a by a fixing member 16 such as a bolt and a pin. Move. 14 a is a door opening side smoke shielding material arranged at the door opening side end of the landing door 1. The door guide shoe 13 and the smoke shielding materials 14 and 14 a block the gap between the lower end of the landing door 1 and the upper surface of the sill 11.

一般のエレベータの場合、敷居１１は、乗場ドア１が全開になったときに、ドアガイドシュー１３が敷居溝１１ａから外れない程度の長さになっている。そのため、図９に示すように、乗場ドア１の全開状態では、戸開側遮煙材１４ａの下部の一部は敷居１１からはみ出すことになる。そうすると、乗場ドア１の開閉動作に伴って、戸開側遮煙材１４ａの下部が、敷居１１の戸開側端部の角で擦られて磨耗し、戸開側遮煙材１４ａの早期劣化を招くことになる。   In the case of a general elevator, the sill 11 has such a length that the door guide shoe 13 is not detached from the sill groove 11a when the landing door 1 is fully opened. Therefore, as shown in FIG. 9, in the fully open state of the landing door 1, a part of the lower part of the door opening side smoke shielding material 14 a protrudes from the sill 11. Then, with the opening / closing operation of the landing door 1, the lower part of the door opening side smoke shielding material 14a is rubbed and worn at the corner of the door opening side end portion of the sill 11, and the door opening side smoke shielding material 14a is prematurely deteriorated. Will be invited.

そこでこの問題を解決するために、敷居１１の戸開側端部に戸開側遮煙材１４ａをガイドするための敷居延長ガイドを設ける構成が考えられている。
この構成を図１１，図１２により説明する。図１１は図９に相当する図、図１２は図１０に相当する図である。 In order to solve this problem, a configuration in which a sill extension guide for guiding the door opening side smoke shielding material 14a is provided at the door opening side end of the sill 11 is considered.
This configuration will be described with reference to FIGS. 11 is a diagram corresponding to FIG. 9, and FIG. 12 is a diagram corresponding to FIG.

図において、２２は縦断面Ｚ字状（クランク状）の敷居延長ガイドであり、敷居２５の上面を乗場ドア１の戸開方向に延長する延長部２２ａと敷居２５の昇降路側端部に固定された固定部２２ｂとを有している。戸開側遮煙材１４ａの下部は、乗場ドア１が全開状態になった際に敷居２５及び延長部２２ａによって支持される。
敷居２５の下部には、溝内部に比べ間口が狭いアリ溝２５ａが設けられており、このアリ溝２５ａの内部には、固定用部材であるボルト２７のボルト頭２７ａがはめ込まれている。そしてボルト２７には、固定部２２ｂを貫通した後にナット２８が螺合されている。これにより、固定部２２ｂはボルト２７及びナット２８によって敷居２５の戸開側端部に取り付けられる。 In the figure, reference numeral 22 denotes a sill extension guide having a Z-shaped (crank) cross section, which is fixed to an extension part 22a that extends the upper surface of the sill 25 in the door opening direction of the landing door 1 and the hoistway side end of the sill 25. And a fixing portion 22b. The lower part of the door opening side smoke shielding material 14a is supported by the sill 25 and the extension 22a when the landing door 1 is fully opened.
In the lower part of the sill 25, a dovetail groove 25a having a narrower opening than the inside of the groove is provided, and a bolt head 27a of a bolt 27 that is a fixing member is fitted in the dovetail groove 25a. A nut 28 is screwed into the bolt 27 after passing through the fixing portion 22b. Thereby, the fixing | fixed part 22b is attached to the door opening side edge part of the sill 25 with the volt | bolt 27 and the nut 28. FIG.

この従来装置によれば、乗場ドア１が全開状態になった際には、敷居２５の上面及び延長部２２ａによって戸開側遮煙材１４ａの下部が支持されるため乗場ドア１の開閉動作に伴う戸開側遮煙材１４ａの下部が、敷居１１の戸開側端部の角で擦られる可能性が低くなる。これによって、戸開側遮煙材１４ａの早期劣化を防止することができる。   According to this conventional apparatus, when the landing door 1 is fully opened, the upper surface of the sill 25 and the lower portion of the door opening side smoke shielding material 14a are supported by the extension portion 22a. The possibility that the lower part of the accompanying door opening side smoke shielding material 14a is rubbed at the corner of the door opening side end of the sill 11 is reduced. Thereby, the early deterioration of the door opening side smoke shielding material 14a can be prevented.
