Description

エレベータのドア装置Elevator door device
　この発明はエレベータのドア装置に関するものである。 The present invention relates to an elevator door device.
　従来のエレベータのドア装置では、水平移動されて出入口を開閉するドアパネル、ドアパネルの下端部に取り付けられたガイド体、及びガイド体が挿入される敷居溝が上面に設けられており、出入口の床部に設置されている敷居を備え、敷居溝内の側壁には、係合溝が設けられており、ドアパネルの下端部には、係合溝に係合してドアパネルの上方への移動を規制する掛け金具が取り付けられており、掛け金具は、ドアパネルに取り付けられ敷居溝内に挿入された取付部と、取付部から水平に突出して係合溝内に挿入された係合部とを有しているので、万一いたずら等により、過大な力がドアパネルに加わったとしても、ドアパネルの上方へ移動が物理的に規制され、従って、ドアパネルの外力による外れを、簡単な構成により防止することができる。 In a conventional elevator door device, a door panel that is horizontally moved to open and close the doorway, a guide body attached to the lower end of the door panel, and a threshold groove into which the guide body is inserted are provided on the upper surface, and the floor of the doorway is provided. The side wall in the sill groove is provided with an engaging groove, and the lower end of the door panel engages with the engaging groove to restrict the upward movement of the door panel. A hanging bracket is attached, and the hanging bracket has a mounting portion that is attached to the door panel and inserted into the threshold groove, and an engaging portion that protrudes horizontally from the mounting portion and is inserted into the engaging groove. Therefore, even if an excessive force is applied to the door panel due to mischief or the like, the movement of the door panel upward is physically restricted, and therefore the door panel can be prevented from coming off due to an external force by a simple configuration. ..

　次に、本発明の実施の形態１によるエレベータのドア装置の動作を説明する。 Next, the operation of the elevator door device according to the first embodiment of the present invention will be described.
　乗場戸１０の乗場２側から昇降路１側に押し付け力Ｐが作用すると、ドアシュ２２が乗場敷居８の案内溝８ａの昇降路１側の側面に押し付けられて反力Ｒｈ１が生じるとともに、ハンガーローラ２０のローラ２６のフランジ部２６ｂがドアレール１５の乗場２側の側面に押し付けられて反力Ｒｈ２が生じる。 When a pressing force P acts from the landing 2 side of the landing door 10 to the hoistway 1 side, the door ash 22 is pressed against the side surface of the guide groove 8a of the landing threshold 8 on the hoistway 1 side to generate a reaction force Rh1 and a hanger roller. The flange portion 26b of the roller 26 of the 20 is pressed against the side surface of the door rail 15 on the landing 2 side to generate a reaction force Rh2.
　ここで、押し付け力Ｐ、反力Ｒｈ１、および反力Ｒｈ２の関係は、式（１）で表される。 Here, the relationship between the pressing force P, the reaction force Rh1, and the reaction force Rh2 is expressed by the equation (1).
　Ｐ＝Ｒｈ１＋Ｒｈ２・・・（１） P = Rh1 + Rh2 ... (1)
　また、押し付け力Ｐにより乗場戸１０が昇降路１側に反って下部ストッパ２３が乗場敷居８の上面に押し付けられると、反力Ｒｖ１が生じる。 Further, when the landing door 10 is bent toward the hoistway 1 side and the lower stopper 23 is pressed against the upper surface of the landing threshold 8 by the pressing force P, a reaction force Rv1 is generated.
　さらに、反力Ｒｖ１により乗場戸１０が上方向に押され、上部ストッパ２１がドアレール１５の下面に押し付けられて反力Ｒｖ２が生じる。 Further, the landing door 10 is pushed upward by the reaction force Rv1, the upper stopper 21 is pressed against the lower surface of the door rail 15, and the reaction force Rv2 is generated.
　ここで、反力Ｒｖ１および反力Ｒｖ２の関係は、式（２）で表される。 Here, the relationship between the reaction force Rv1 and the reaction force Rv2 is expressed by the equation (2).
　Ｒｖ１＝Ｒｖ２・・・（２） Rv1 = Rv2 ... (2)
　反力Ｒｖ１および反力Ｒｖ２により、乗場戸１０が前記敷居８の上面とドアレール１５の下面との間で突っ張り、前記戸の反りを抑制する。 Due to the reaction force Rv1 and the reaction force Rv2, the landing door 10 is stretched between the upper surface of the threshold 8 and the lower surface of the door rail 15 to suppress the warp of the door.
　本発明の実施の形態１によるエレベータのドア装置では、乗場戸１０が表側から押された際に、乗場戸１０の反りを抑制し、乗場戸１０が乗場敷居８およびドアレール１５から外れるのを防止できる。 In the elevator door device according to the first embodiment of the present invention, when the landing door 10 is pushed from the front side, the warp of the landing door 10 is suppressed and the landing door 10 is prevented from coming off from the landing threshold 8 and the door rail 15. it can.
　また、下部ストッパ２３は、ドアシュ２２と共に戸本体１８のドアシュ取付け部１８ｂにボルト３１で固定されるので、下部ストッパ２３を容易に取り付けることができる。特に、戸本体１８、ドアシュ２２、および乗場敷居８を備えた既設のエレベータのドア装置に、乗場戸や乗場敷居を交換したり加工したりすることなく下部ストッパ２３を容易に取り付けることができる。 Further, since the lower stopper 23 is fixed to the doorsh attachment portion 18b of the door body 18 together with the doorsh 22 with a bolt 31, the lower stopper 23 can be easily attached. In particular, the lower stopper 23 can be easily attached to the door device of the existing elevator provided with the door main body 18, the door shoe 22, and the landing threshold 8 without exchanging or processing the landing door or the landing threshold.
　また、下部ストッパー２３は、形状がＬ字を成しているので、鋼板を曲げて容易に製作することができるとともに、戸本体１８の昇降路１側の側面および乗場敷居８の上面に沿って取り付けられているので、設置に必要なスペースを小さくすることができる。 Further, since the lower stopper 23 has an L shape, it can be easily manufactured by bending a steel plate, and along the side surface of the door body 18 on the hoistway 1 side and the upper surface of the landing threshold 8. Since it is attached, the space required for installation can be reduced.
　なお、下部ストッパ２３は、ドアシュ２２と共に戸本体１８のドアシュ取付け部１８ｂに固定されているが、ドアシュ２２と共にドアシュ取付け部１８ｂに固定されなくてもよく、戸本体１８に固定されればよい。この場合も、本発明の実施の形態１によるエレベータのドア装置の前述の効果と同様の効果を奏する。 Although the lower stopper 23 is fixed to the doorsh mounting portion 18b of the door body 18 together with the doorsh 22, it does not have to be fixed to the doorsh mounting portion 18b together with the doorsh 22 and may be fixed to the door body 18. In this case as well, the same effect as the above-mentioned effect of the elevator door device according to the first embodiment of the present invention is obtained.
　なお、下部ストッパー２３は、１つの鋼板が曲折して形成されなくてもよく、戸本体１８から乗場戸１０の裏方向にかつ乗場敷居８の上面に向かって伸びていればよい。この場合も、本発明の実施の形態１によるエレベータのドア装置の前述の効果と同様の効果を奏する。 The lower stopper 23 does not have to be formed by bending one steel plate, and may extend from the door body 18 in the back direction of the landing door 10 and toward the upper surface of the landing threshold 8. In this case as well, the same effect as the above-mentioned effect of the elevator door device according to the first embodiment of the present invention is obtained.
　なお、下部ストッパ２３は、乗場敷居８の上面と隙間をあけて取り付けられていても、隙間をあけずに取り付けられていてもよく、乗場戸１０が乗場敷居８から外れる前に下部ストッパ２３が乗場敷居８の上面に押し付けられればよい。この場合も、本発明の実施の形態１によるエレベータのドア装置の前述の効果と同様の効果を奏する。 The lower stopper 23 may be attached with a gap from the upper surface of the landing threshold 8, or may be attached without a gap, and the lower stopper 23 may be attached before the landing door 10 is removed from the landing threshold 8. It may be pressed against the upper surface of the landing threshold 8.

FIG. 6 is a cross-sectional view showing a first modification of the elevator door device as viewed from the direction of the arrow indicated by CC in FIG. FIG. 6 shows a state in which the landing door 10 is not warped.
　下部ストッパ３３は、押し付け力Ｐにより乗場敷居８の上面に押し付けられる押し付け面３３ａの表面の粗さが、押し付け面３３ａ以外の面の表面の粗さよりも粗く加工されている。この加工は、例えば、塑性加工、切削加工、溶解加工、およびコーティング加工である。下部ストッパ３３は、この加工以外はストッパ２３と同じである。 The lower stopper 33 is processed so that the surface roughness of the pressing surface 33a pressed against the upper surface of the landing threshold 8 by the pressing force P is rougher than the surface roughness of the surfaces other than the pressing surface 33a. This processing is, for example, plastic working, cutting, melting, and coating. The lower stopper 33 is the same as the stopper 23 except for this processing.
　この場合も、本発明の実施の形態１によるエレベータのドア装置の前述の効果と同様の効果を奏する。 Also in this case, the same effect as the above-mentioned effect of the elevator door device according to the first embodiment of the present invention is obtained.
　また、上部ストッパ３３が乗場敷居８の上面を滑りにくくなって反力Ｒｖ１を受けやすくなり、乗場戸１０が前記敷居８の上面とドアレール１５の下面との間で突っ張って乗場敷居８およびドアレール１５から外れにくくすることができる。 Further, the upper stopper 33 is less likely to slip on the upper surface of the landing threshold 8 and is more likely to receive the reaction force Rv1, and the landing door 10 is stretched between the upper surface of the threshold 8 and the lower surface of the door rail 15 to make the landing threshold 8 and the door rail 15 difficult to slip. It can be made difficult to come off from.

In this case as well, the same effect as the above-mentioned effect of the elevator door device according to the first embodiment of the present invention is obtained.
　なお、上部ストッパ２１は、ドアレール１５の下面と隙間をあけて取り付けられていても、隙間をあけずに取り付けられていてもよく、乗場戸１０がドアレール１５から外れる前に上部ストッパ２１がドアレール１５の下面に押し付けられればよい。この場合も、本発明の実施の形態１によるエレベータのドア装置の前述の効果と同様の効果を奏する。 The upper stopper 21 may be attached with a gap from the lower surface of the door rail 15, or may be attached without a gap, and the upper stopper 21 may be attached to the door rail 15 before the landing door 10 comes off the door rail 15. It may be pressed against the lower surface of the. In this case as well, the same effect as the above-mentioned effect of the elevator door device according to the first embodiment of the present invention is obtained.
