Description

本発明は、エレベーター装置に係り、特に、火災時に昇降路と乗場との間の煙の貫流を防止し得るエレベーター装置に関する。 The present invention relates to an elevator apparatus, and more particularly to an elevator apparatus that can prevent smoke from flowing between a hoistway and a landing during a fire.

従来から、火災時に昇降路と乗場との間の煙の貫流を防止し得るエレベーター装置は、既に提案されている。例えば、特許文献１には、乗降口を区画する三方枠を形成する上枠と、乗降口を横方向に開閉する乗場ドアとの間の隙間に、板ばねを設け、この板ばねが滑り材を押付けることにより、煙の貫流を防止することが記載されている。 Conventionally, an elevator apparatus that can prevent smoke from flowing between a hoistway and a landing during a fire has already been proposed. For example, in Patent Document 1, a leaf spring is provided in a gap between an upper frame that forms a three-way frame that partitions the entrance and exit and a landing door that opens and closes the entrance and exit in a lateral direction. It is described that smoke is prevented from flowing through by pressing.

しかしながら、上記特許文献１では、乗場ドアが開閉するとき、板ばねと滑り材との間に摩擦が生じるため、乗場ドアの開閉性能に影響を及ぼす可能性がある。 However, in Patent Document 1, when the landing door opens and closes, friction is generated between the leaf spring and the sliding material, which may affect the opening and closing performance of the landing door.

本発明の目的は、乗場ドアが開閉するときの摩擦を低減し、乗場ドアの開閉性能への影響を抑えることのできるエレベーター装置を提供することにある。 The objective of this invention is providing the elevator apparatus which can reduce the friction when a landing door opens and closes, and can suppress the influence on the opening / closing performance of a landing door.

上記目的を達成するために、本発明では、昇降路と乗場との間を連通する乗降口を区画し両縦枠と上枠とを有する三方枠と、前記乗場の昇降路側端に設けられた敷居と、前記敷居に案内されて前記乗降口を横方向に開閉する乗場ドアを備えたエレベーター装置において、前記乗場ドアと前記三方枠との間の隙間を塞ぐ板ばねを取付け、この板ばねに穴を設けることにより、板ばねの押付け力を低減したのである。 In order to achieve the above object, in the present invention, a three-way frame having both a vertical frame and an upper frame that divides an entrance and exit that communicates between the hoistway and the landing, and provided at the hoistway side end of the landing. In an elevator apparatus provided with a sill and a landing door that is guided by the sill and opens and closes the entrance / exit sideways, a leaf spring that closes a gap between the landing door and the three-way frame is attached, and the leaf spring is attached to the leaf spring. By providing the hole, the pressing force of the leaf spring was reduced.

本発明によれば、乗場ドアが開閉するときの摩擦を低減し、乗場ドアの開閉性能への影響を抑えたエレベーター装置を提供することができる。 ADVANTAGE OF THE INVENTION According to this invention, the friction at the time of a landing door opening and closing can be reduced, and the elevator apparatus which suppressed the influence on the opening / closing performance of a landing door can be provided.

以下、本発明の実施例について、図１〜図３を用いて説明する。 Embodiments of the present invention will be described below with reference to FIGS.

図１は、本発明の実施例におけるエレベーター装置の乗場付近を示す図である。このエレベーター装置は、周囲を壁で覆われて建築物１内を上下方向に貫通する昇降路２と、建築物１の各階床に設けられた乗場３と、昇降路２と乗場３との間を連通する乗降口４と、昇降路２内をロープ等で吊り下げられて昇降する乗りかご５を備えている。 FIG. 1 is a view showing the vicinity of a landing of an elevator apparatus according to an embodiment of the present invention. This elevator apparatus includes a hoistway 2 that is covered with walls and penetrates the building 1 in the vertical direction, a hall 3 provided on each floor of the building 1, and between the hoistway 2 and the hall 3. And a passenger car 5 that is lifted and lowered by being suspended in the hoistway 2 with a rope or the like.

乗降口４は、四角に開口しており、その両側縁と上縁との三方を意匠品である三方枠６で被っている。この三方枠６は、断面がコの字状をなしており、乗降口４の両側縁と上縁に沿うように、左右の両縦枠６Ａ，６Ｂと上枠６Ｃとから構成され、乗降口４を区画している。そして、三方枠６で囲まれていない乗場３の昇降路側端部には、敷居７が設けられている。 The entrance / exit 4 is opened in a square, and covers the three sides of the both side edges and the upper edge with a three-way frame 6 which is a design product. The three-way frame 6 has a U-shaped cross section, and is composed of left and right vertical frames 6A and 6B and an upper frame 6C so as to be along the both side edges and the upper edge of the entrance / exit. 4 is divided. A threshold 7 is provided at the hoistway side end of the hall 3 that is not surrounded by the three-way frame 6.

また、三方枠６で囲まれた乗降口４は、昇降路２に面する側に位置する乗場ドア８で横方向に開閉される。この乗場ドア８は、左右両開きの２枚の乗場ドア８Ａ，８Ｂからなり、各乗場ドア８Ａ，８Ｂは、その上部でハンガ９により、建築壁１Ｗに横方向に固定したポケット１０内のドアレール１１上に案内させることで吊り下げられている。乗場ドア
８Ａ，８Ｂの下部には、ドアシュー１２が固定され、このドアシュー１２を敷居７の溝内で摺動させることで、乗場ドア８Ａ，８Ｂの下部を案内している。 Moreover, the entrance / exit 4 surrounded by the three-way frame 6 is opened / closed laterally by a landing door 8 located on the side facing the hoistway 2. The landing door 8 is composed of two landing doors 8A and 8B which are double-sided. Each landing door 8A and 8B has a door rail 11 in a pocket 10 fixed laterally to the building wall 1W by a hanger 9 at the top. It is suspended by guiding it up. A door shoe 12 is fixed to the lower part of the landing doors 8A and 8B, and the lower part of the landing doors 8A and 8B is guided by sliding the door shoe 12 in the groove of the sill 7.

更に、上記構成において、乗場ドア８Ａ，８Ｂが乗降口４を開閉するためには、図２に示すように、乗場ドア８Ａ（８Ｂ）と上枠６Ｃとの間に隙間Ｇ１，乗場ドア８Ａ（８Ｂ）と敷居７との間に隙間Ｇ２を、それぞれ必要とするが、一方で、これら隙間Ｇ１，Ｇ２は、火災時の乗場３と昇降路２の間に煙の貫流を生じさせる要因になる。 Further, in the above configuration, in order for the landing doors 8A and 8B to open and close the entrance / exit 4, as shown in FIG. 2, there is a gap G1 between the landing door 8A (8B) and the upper frame 6C and the landing door 8A ( 8B) and the sill 7 require gaps G2, respectively. On the other hand, these gaps G1 and G2 cause smoke to flow between the landing 3 and the hoistway 2 during a fire. .

本実施例では、これら隙間Ｇ１，Ｇ２からの煙の貫流を防ぐため、隙間Ｇ１の側部を塞ぐ側部遮煙体及び隙間Ｇ２を塞ぐ下部遮煙体とを乗場ドア８Ａ，８Ｂに取付け、隙間Ｇ１の上部を塞ぐ上部遮煙体１３を上枠１６Ｃに取付けている。また、各乗場ドア８Ａ，８Ｂの戸当り側には、それぞれ戸当りゴムが設けられているので、乗場ドア８Ａ，８Ｂどうしが直接突き当たって衝突音が発生するのを防止でき、乗場ドア８Ａ，８Ｂが損傷することもない。 In this embodiment, in order to prevent the smoke from flowing through the gaps G1 and G2, side smoke shields that close the sides of the gap G1 and lower smoke shields that close the gap G2 are attached to the landing doors 8A and 8B. An upper smoke shield 13 that closes the upper portion of the gap G1 is attached to the upper frame 16C. Also, since the door stop rubber is provided on the door stop side of each landing door 8A, 8B, it is possible to prevent the landing doors 8A, 8B from directly colliding with each other and to generate a collision sound. 8B is not damaged.

上部遮煙体１３は、乗場ドア８Ａ，８Ｂの上部付近において、具体的には、昇降路側から見て乗場ドア８Ａ，８Ｂと上枠６Ｃとが重なる領域において、乗場ドア８Ａ，８Ｂの表面側へ突出するように上枠６Ｃに取付けられた金属製の上枠板ばね１３Ａと、上枠滑り材１３Ｂからなる。そして、上枠板ばね１３Ａの一端は、長手方向の複数箇所で固定ねじ
１４により上枠６Ｃへ取付けられ、上枠板ばね１３Ａの他端は、上枠滑り材１３Ｂを介して乗場ドア８Ａ，８Ｂに摺動圧接される。 The upper smoke shield 13 is located near the upper side of the landing doors 8A and 8B, specifically, in the region where the landing doors 8A and 8B and the upper frame 6C overlap when viewed from the hoistway side, the surface side of the landing doors 8A and 8B. The upper frame leaf spring 13A is attached to the upper frame 6C so as to protrude to the upper frame 6C, and the upper frame sliding member 13B. One end of the upper frame leaf spring 13A is attached to the upper frame 6C by fixing screws 14 at a plurality of locations in the longitudinal direction, and the other end of the upper frame leaf spring 13A is attached to the landing door 8A via the upper frame sliding member 13B. 8B is slidably pressed.

一方、乗場ドア８Ａ，８Ｂには、乗場ドア８Ａ，８Ｂの開閉動作中に上枠滑り材１３Ｂと摺動する乗場ドア上部滑り材１６が、上枠滑り材１３Ｂと対向するように設けられている。また、上枠滑り材１３Ｂと乗場ドア上部滑り材１６，上枠滑り材１３Ｂと上枠板ばね１３Ａは、それぞれ横方向全域において接するように構成されているので、乗場ドア８Ａ，８Ｂの開閉時、乗場ドア８Ａ，８Ｂの上部と上枠６Ｃとの間の隙間を塞ぐことになる。 On the other hand, the landing doors 8A and 8B are provided with a landing door upper sliding material 16 that slides on the upper frame sliding material 13B during the opening / closing operation of the landing doors 8A and 8B so as to face the upper frame sliding material 13B. Yes. Further, since the upper frame sliding material 13B and the landing door upper sliding material 16, and the upper frame sliding material 13B and the upper frame leaf spring 13A are configured to contact each other in the entire lateral direction, the landing doors 8A and 8B are opened and closed. The gaps between the upper portions of the landing doors 8A and 8B and the upper frame 6C are closed.

更に、図３に示すように、上枠板ばね１３Ａには、切欠穴１３Ｃが長手方向に複数設けられており、上部滑り材１３Ｂもしくは乗場ドア上部滑り材１６を押付ける上枠板ばね
１３Ａの力を低減している。その結果、乗場ドア開閉時の摺動摩擦が低減され、乗場ドアの開閉性能への影響を抑えることができる。特に、上枠板ばね１３Ａを上枠６Ｃに取付ける固定ねじ１４の近傍は、荷重が集中するので、この複数の固定箇所の近傍において、上枠板ばね１３Ａに切欠穴１３Ｃを設ければ、摩擦低減の効果がより大きくなる。また、切欠穴１３Ｃの大きさ，位置等を変えることにより、上枠板ばね１３Ａの押付け力を調整することも可能である。尚、切欠穴１３Ｃは、粘着テープ１３Ｄを貼って塞ぐ構造にしているので、遮煙性は確保される。 Further, as shown in FIG. 3, the upper frame leaf spring 13A is provided with a plurality of cutout holes 13C in the longitudinal direction, and the upper frame leaf spring 13A for pressing the upper sliding material 13B or the landing door upper sliding material 16 is provided. Power is reduced. As a result, sliding friction during opening / closing of the landing door is reduced, and the influence on the opening / closing performance of the landing door can be suppressed. In particular, the load concentrates in the vicinity of the fixing screw 14 for attaching the upper frame leaf spring 13A to the upper frame 6C. Therefore, if the notch holes 13C are provided in the upper frame leaf spring 13A in the vicinity of the plurality of fixing portions, the friction is caused. The effect of reduction becomes greater. It is also possible to adjust the pressing force of the upper frame leaf spring 13A by changing the size, position, etc. of the cutout hole 13C. In addition, since the notch hole 13C has a structure in which the adhesive tape 13D is attached and closed, smoke shielding is ensured.
