図3から図8に基づいて、この実施の形態のエレベータの出入口装置を説明する。図3は、この発明の実施の形態1を示す要部斜視図である。図4は、図3の戸当下部気密部品7を外した図である。図5は、図4の下部気密部品を外した図である。図6は、この発明の実施の形態1を示す要部を戸当側から見た側面図である。図7は、図6の戸当下部気密部品7を外した図である。図8は、戸当下部気密部品7の斜視図である。  The elevator doorway apparatus according to this embodiment will be described with reference to FIGS. FIG. 3 is a perspective view showing a main part of the first embodiment of the present invention. FIG. 4 is a view in which the door bottom lower airtight part 7 of FIG. 3 is removed. FIG. 5 is a view in which the lower airtight part of FIG. 4 is removed. FIG. 6 is a side view of the main part showing Embodiment 1 of the present invention as seen from the door side. FIG. 7 is a view in which the door stopper lower airtight part 7 of FIG. 6 is removed. FIG. 8 is a perspective view of the door stopper lower airtight component 7.

図3に示すように、引き戸3は、戸当側端部が水平断面コ字状に屈曲成形され、戸当面3Aを形成する。また、図4及び図5に示すように、戸当面3Aの下端は、切欠き部3Bが形成されている。戸当気密部品5は、屈曲成形された、昇降路側の面に、上下に渡って設けられる。戸当気密部品5は、その一端部が引き戸3の戸当面3Aよりも突出して設けられる。この戸当気密部品5は、戸全閉時に互いに当接し、両方の戸当面3Aの間に生じる隙間を閉塞する。  As shown in FIG. 3, the sliding door 3 is bent and formed into a U-shaped horizontal section at the door side, and forms a door surface 3 </ b> A. Moreover, as shown in FIG.4 and FIG.5, the notch part 3B is formed in the lower end of the door stop surface 3A. The door-to-door airtight component 5 is provided over the hoistway side, which is bent and formed, up and down. One end of the door seal airtight component 5 is provided so as to protrude from the door contact surface 3 </ b> A of the sliding door 3. The door seal airtight component 5 abuts each other when the door is fully closed, and closes a gap generated between both door contact surfaces 3A.

下部気密部品6は、図4に示すように、その上部が昇降路側から引き戸3の下端に当接し、ネジ10によって引き戸3の下端に戸開閉方向に渡って固定される。この下部気密部品6は、引き戸3の下端部と平行な鉛直部6Cとこの鉛直部6Cの下端から水平方向に形成された突出部6Dとを有するL字状の弾性材で構成される。L字状の弾性材の、それぞれ他方の引き戸側に対向する端部には、戸当下部気密部品7の一部が当接する段部で形成された固定部6Bと戸当下部気密部品7の一部が当接する当接部6Eとを有する。
突出部6Dは、鉛直部6Cの下端から乗りかご側に突出し、また突出する先端部は、鉛直断面が曲面になっている接触部6Aを有する。この接触部6Aは、敷居4の溝に挿入され、図7に示すように、敷居4の溝を形成する鉛直面のうち、乗りかご(図示せず)側と常に当接している。これにより、引き戸3と敷居4との間に生じる隙間を閉塞できる。接触部6Aは、断面が曲面になっているので、敷居4の溝の鉛直面との接触面積が小さくなる。そのため、戸開閉時は、摩擦抵抗が低減され、戸開閉動作がスムーズである。
As shown in FIG. 4, the lower airtight component 6 abuts on the lower end of the sliding door 3 from the hoistway side and is fixed to the lower end of the sliding door 3 by screws 10 in the door opening / closing direction. The lower airtight component 6 is formed of an L-shaped elastic material having a vertical portion 6C parallel to the lower end portion of the sliding door 3 and a protruding portion 6D formed in the horizontal direction from the lower end of the vertical portion 6C. At the end of the L-shaped elastic material facing the other sliding door side, there is a fixing portion 6B formed by a step portion with which a portion of the door-holding airtight part 7 abuts and a door-holding airtight part 7 And a contact portion 6E that a part thereof contacts.
The protruding portion 6D protrudes from the lower end of the vertical portion 6C toward the car, and the protruding tip has a contact portion 6A having a curved vertical cross section. This contact portion 6A is inserted into the groove of the sill 4 and, as shown in FIG. 7, is always in contact with the car (not shown) side of the vertical surface forming the groove of the sill 4. Thereby, the clearance gap produced between the sliding door 3 and the threshold 4 can be obstruct | occluded. Since the cross section of the contact portion 6A is a curved surface, the contact area with the vertical surface of the groove of the sill 4 is reduced. Therefore, when the door is opened and closed, the frictional resistance is reduced, and the door opening and closing operation is smooth.

次に、戸当下部気密部品7の構成について、図8に基づいて説明する。
戸当下部気密部品7は、図8に示すように、本体7Cと接触部材7Gとから構成される。本体7Cは、底部7Fと、この底部7Fからそれぞれ鉛直方向に延びる第1の鉛直部7D及び第2の鉛直部7Eとを有し、これらにより凹部を形成する。第1の鉛直部7Dと第2の鉛直部7Eは、平行に設けられており、第1の鉛直部7Dは、第2の鉛直部7Eよりも水平方向に長く、鉛直方向に短い寸法となっている。一方、接触部材7Gは、この第1の鉛直部7Dから下方に延びたL字状を成し、下部気密部品6の接触部6Aと同様の形状をなす接触部7Aを形成している。
戸当下部気密部品7の本体7Cの凹部は、引き戸3の戸当面3Aの下端に成形された切欠き部3Bに嵌め込み可能で、嵌め込むと、第1の鉛直部7Dの内面が戸当面3Aの外側と当接し、第2の鉛直部7Eの内面が戸当面3Aの内側と当接するとともに、底部7Fの内面が切欠き部3Bの縁部と当接する。また、底部7Fの外面は、下部気密部品6の固定部6Bに当接する。ここで、第2の鉛直部7Eは、水平方向の寸法が戸当面3Aの幅よりも短くなっている。このため、戸当下部気密部品7を戸当面3Aの下端に成形された切欠き部3Bに嵌め込むと、引き戸3のコ字状部の内側には、コ字の向かい合う2つの面と第2の鉛直部7Eの両側面との間に、それぞれ空間11が生じる。
図6に示すように、戸当下部気密部品7の接触部7Aも、敷居4の溝を形成する鉛直面のうち、乗りかご(図示せず)側と常に当接しているが、戸開閉時は摩擦抵抗が低減される形状になっているので、戸開閉動作がスムーズである。なお、戸当下部気密部品7は、弾性材、例えば、クロロプレンゴム、エチレンプロピレンゴム等から成る。このため、戸当下部気密部品7の凹部を形成する第1及び第2の鉛直部7D、7Eは、引き戸3の開閉方向に弾性力を有し、前記凹部を引き戸3の戸当面3Aの下端に成形された切欠き部3Bに挿入すると、第1及び第2の鉛直部7D、7Eは、弾性力により引き戸3の戸当面3Aの切欠き部3Bを含む下端を挟み込み、これにより戸当面3Aの下端を嵌合することができる。
なお、第1の鉛直部7Dは、第2の鉛直部7Eと比べて、鉛直方向に短い寸法となっているとしたが、これに限らず、同じ寸法でも良い。
Next, the structure of the door stopper lower part airtight component 7 is demonstrated based on FIG.
As shown in FIG. 8, the door bottom lower airtight component 7 is composed of a main body 7 </ b> C and a contact member 7 </ b> G. The main body 7C has a bottom portion 7F, and a first vertical portion 7D and a second vertical portion 7E that respectively extend in the vertical direction from the bottom portion 7F, thereby forming a recess. The first vertical portion 7D and the second vertical portion 7E are provided in parallel, and the first vertical portion 7D is longer in the horizontal direction than the second vertical portion 7E and shorter in the vertical direction. ing. On the other hand, the contact member 7G has an L shape extending downward from the first vertical portion 7D and forms a contact portion 7A having the same shape as the contact portion 6A of the lower airtight component 6.
The concave portion of the main body 7C of the door-holding lower part 7 can be fitted into a notch 3B formed at the lower end of the door-holding surface 3A of the sliding door 3, and when fitted, the inner surface of the first vertical portion 7D is the door surface 3A. The inner surface of the second vertical portion 7E contacts the inner side of the door contact surface 3A, and the inner surface of the bottom portion 7F contacts the edge of the notch portion 3B. Further, the outer surface of the bottom 7 </ b> F comes into contact with the fixing portion 6 </ b> B of the lower airtight component 6. Here, the second vertical portion 7E has a horizontal dimension shorter than the width of the door contact surface 3A. For this reason, when the door-holding airtight part 7 is fitted into the notch 3B formed at the lower end of the door-holding surface 3A, two U-faces facing each other and the second face are formed on the inside of the U-shaped portion of the sliding door 3. A space 11 is created between each side surface of the vertical portion 7E.
As shown in FIG. 6, the contact portion 7 </ b> A of the door-holding lower airtight component 7 is always in contact with the car (not shown) side of the vertical surface forming the groove of the sill 4. Since the frictional resistance is reduced, the door opening and closing operation is smooth. The door bottom lower airtight component 7 is made of an elastic material such as chloroprene rubber or ethylene propylene rubber. For this reason, the 1st and 2nd vertical parts 7D and 7E which form the recessed part of the door-holding lower part airtight component 7 have elastic force in the opening-and-closing direction of the sliding door 3, and the said recessed part is the lower end of 3 A of dooring surfaces of the sliding door 3 When inserted into the notch 3B formed in the shape, the first and second vertical portions 7D and 7E sandwich the lower end including the notch 3B of the door contact surface 3A of the sliding door 3 by elastic force, and thereby the door contact surface 3A. The lower end of can be fitted.
In addition, although 1st vertical part 7D was taken as the dimension short in the perpendicular direction compared with 2nd vertical part 7E, it is not restricted to this, The same dimension may be sufficient.

次に下部気密部品6及び戸当下部気密部品7の取付方法を説明する。
戸当下部気密部品7の本体7Cの凹部の溝を下方から図5に示す、引き戸3の戸当面3Aの下端の切欠き部3Bに向けた状態で当該凹部の溝を切欠き部3Bに嵌め込む。これにより戸当下部気密部品7と切欠き部とが嵌合する。戸当下部気密部品7を引き戸3の切欠き部3Bに嵌合すると、戸当下部気密部品7の当接部7Bは、戸当気密部品5の下端と当接するので、気密性が向上する。ここで、引き戸3のコ字状部の内側には、コ字の向かい合う2つの面と第2の鉛直部7Eの両側面との間にそれぞれ空間11が生じる。この空間11の分、図6に示す矢印aの方向に、戸当下部気密部品7は、取付位置を調整できる。これにより、据付誤差に応じて、戸当下部気密部品7の敷居4への押圧量を調整し、良好な気密状態を確保できる。なお、戸当下部気密部品7の取付位置を調整しても、当接部7Bは戸当気密部品5の下端と常に当接している。戸当下部気密部品7の取付位置を調整した後に、下部気密部品6を引き戸3の下端に取付ける。下部気密部品6を固定すると、下部気密部品6の固定部6Bが戸当下部気密部品7の底部7Fに当接し、戸当下部気密部品7を固定する。これにより、戸当下部気密部品7は、上下方向と戸開閉方向への移動が規制されるため、脱落の恐れがない。また、戸当下部気密部品7の固定は、下部気密部品6を引き戸3から取外すことで解除されるので、保守交換時の作業も容易である。
Next, the attachment method of the lower airtight part 6 and the door stop lower airtight part 7 is demonstrated.
The groove of the concave portion of the main body 7C of the door-holding air-tight part 7 is fitted into the notch 3B with the groove of the concave portion facing the notch 3B at the lower end of the door surface 3A of the sliding door 3 as shown in FIG. Include. Thereby, the door stopper lower part airtight component 7 and a notch part fit. When the door lock lower airtight component 7 is fitted into the cutout portion 3B of the sliding door 3, the contact portion 7B of the door lock lower airtight component 7 comes into contact with the lower end of the door lock airtight component 5, thereby improving the airtightness. Here, on the inner side of the U-shaped portion of the sliding door 3, spaces 11 are respectively formed between the two surfaces facing the U-shape and the both side surfaces of the second vertical portion 7 </ b> E. For the space 11, the door bottom lower airtight component 7 can adjust the mounting position in the direction of the arrow a shown in FIG. 6. Thereby, according to an installation error, the pressing amount to the sill 4 of the door stopper lower part airtight component 7 can be adjusted, and a favorable airtight state can be ensured. Even if the mounting position of the door-holding airtight part 7 is adjusted, the contact portion 7B is always in contact with the lower end of the door-to-door airtight part 5. After adjusting the mounting position of the door bottom lower airtight part 7, the lower airtight part 6 is attached to the lower end of the sliding door 3. When the lower airtight component 6 is fixed, the fixing portion 6B of the lower airtight component 6 comes into contact with the bottom 7F of the door lock lower airtight component 7, and the door lock lower airtight component 7 is fixed. Thereby, since the movement to the up-down direction and a door opening / closing direction is controlled, the door bottom lower part airtight component 7 does not have the possibility of dropping off. Further, the fixing of the door-holding lower airtight part 7 is released by removing the lower airtight part 6 from the sliding door 3, so that the work at the time of maintenance replacement is also easy.

図9は、図2のA−A断面図である。図10は、図9の戸開時の図である。図11は、図9のB−B断面図である。図12は、図10のB−B断面図である。
この実施の形態におけるエレベータの出入口装置においては、図9及び図11に示すように、戸全閉時に引き戸3,3の戸当面3A,3Aの下部と敷居4との間に生じる隙間を戸当下部気密部品7が閉塞する。これにより、乗りかごの気密性が向上する。
9 is a cross-sectional view taken along the line AA in FIG. FIG. 10 is a view when the door of FIG. 9 is opened. 11 is a cross-sectional view taken along line BB in FIG. 12 is a cross-sectional view taken along the line BB in FIG.
In the elevator doorway apparatus in this embodiment, as shown in FIG. 9 and FIG. 11, a gap generated between the lower part of the door contact surfaces 3A and 3A of the sliding doors 3 and 3 and the sill 4 when the door is fully closed The airtight part 7 is closed. This improves the airtightness of the car.

この実施の形態によると、戸当気密部品5、下部気密部品6に加えて、戸当下部気密部品7を設けたことにより、戸全閉時における乗りかごの気密性を向上できる。戸当下部気密部品7は、引き戸3の戸当面3Aの下端に嵌合し、下部気密部品6で当接固定するだけで取付けが可能で、取付作業が容易である。また、戸当下部気密部品7は、下部気密部品6によって当接固定されると、上下方向と戸開閉方向への移動が規制されるため、戸開時に乗客等が誤って衝突しても、脱落の恐れがない。更に、下部気密部品6及び戸当下部気密部品7は、引き戸3の開閉時に敷居4との摩擦抵抗を低減できる形状となっているので、戸開閉動作がスムーズである。加えて、戸当下部気密部品7の取付位置を調整することで良好な気密状態を確保できる。  According to this embodiment, in addition to the door-to-door airtight component 5 and the lower air-tight component 6, by providing the door-to-door lower airtight component 7, the airtightness of the car when the door is fully closed can be improved. The door-holding lower airtight component 7 can be attached simply by fitting to the lower end of the door-holding surface 3A of the sliding door 3 and abutting and fixing with the lower airtight component 6, and the mounting operation is easy. Further, when the door-to-door airtight component 7 is abutted and fixed by the lower airtight component 6, movement in the vertical direction and the door opening / closing direction is restricted. There is no fear of dropping off. Furthermore, since the lower airtight part 6 and the door stopper lower airtight part 7 have a shape that can reduce the frictional resistance with the sill 4 when the sliding door 3 is opened and closed, the door opening and closing operation is smooth. In addition, a favorable airtight state can be secured by adjusting the mounting position of the door-holding lower airtight component 7.

The lower airtight part 6 and the door stop lower airtight part 7 are the same as those in the first embodiment. Other configurations are the same as those in the first embodiment. Also in this embodiment, the abutting portion 7B of the door stopper lower airtight component 7 is always in contact with the lower end of the door stopper airtight component 9. Furthermore, in the direction of the arrow b shown in FIG.

この実施の形態においても、実施の形態1と同様に、戸当気密部品9,9、下部気密部品6,6に加えて、戸当下部気密部品7,7を設けたことにより、戸全閉時における乗りかごの気密性を向上できる。戸当下部気密部品7は、引き戸3の戸当面3Aの下端に嵌合し、下部気密部品6で当接固定するだけで取付けが可能で、取付作業が容易である。また、戸当下部気密部品7は、下部気密部品6によって当接固定されると、上下方向と戸開閉方向への移動が規制されるため、戸開時に乗客等が誤って衝突しても、脱落の恐れがない。更に、下部気密部品6及び戸当下部気密部品7は、引き戸3,3の開閉時に敷居4との摩擦抵抗を低減できる形状となっているので、戸開閉動作がスムーズである。加えて、戸当下部気密部品7の取付位置を調整することで良好な気密状態を確保できる。  Also in this embodiment, in the same manner as in the first embodiment, in addition to the door-to-door airtight parts 9 and 9 and the lower air-tight parts 6 and 6, the door-to-door lower airtight parts 7 and 7 are provided, so that the door is fully closed. The airtightness of the car at the time can be improved. The door-holding lower airtight component 7 can be attached simply by fitting to the lower end of the door-holding surface 3A of the sliding door 3 and abutting and fixing with the lower airtight component 6, and the mounting operation is easy. Further, when the door-to-door airtight component 7 is abutted and fixed by the lower airtight component 6, movement in the vertical direction and the door opening / closing direction is restricted. There is no fear of dropping off. Furthermore, since the lower airtight part 6 and the door stopper lower airtight part 7 have a shape that can reduce the frictional resistance with the sill 4 when the sliding doors 3 and 3 are opened and closed, the door opening and closing operation is smooth. In addition, a favorable airtight state can be secured by adjusting the mounting position of the door-holding lower airtight component 7.
