FIG. 1 is a rear view of the elevator door according to the first embodiment.
図1において、エレベーターのドア1が示される。エレベーターは、複数の階床を有する建築物に設けられる。建築物において、昇降路が、複数の階床にわたって設けられる。エレベーターは、昇降路の内部を鉛直方向に走行するかごによって、複数の階床の間で利用者などを輸送する装置である。かごは、例えば図示されない巻上機などによって昇降路の内部を走行する機器である。巻上機は、例えば昇降路の上部または下部、もしくは昇降路の上方の機械室などに設けられる。巻上機は、例えばかごに設けられるロープを介してかごを走行させる機器である。かごは、かごドアを備える。かごドアは、利用者がかごに乗降しうるように開閉する機器である。かごドアは、かごの内側と昇降路とを空間的に分離することによって利用者などが昇降路へ転落することを防止する。かごドアは、エレベーターのドア1の例である。この例において、エレベーターのドア1は、片開きのドアである。
In FIG. 1, the elevator door 1 is shown. Elevators are installed in buildings with multiple floors. In a building, hoistways are provided over multiple floors. An elevator is a device that transports users and the like between a plurality of floors by a car traveling vertically inside the hoistway. A car is a device that travels inside a hoistway by, for example, a hoist (not shown). The hoisting machine is provided, for example, in the upper or lower part of the hoistway, or in the machine room above the hoistway. The hoisting machine is a device for running the car through, for example, a rope provided in the car. The car is equipped with a car door. A car door is a device that opens and closes so that a user can get in and out of the car. The car door spatially separates the inside of the car from the hoistway to prevent users from falling into the hoistway. The car door is an example of an elevator door 1. In this example, the elevator door 1 is a single door.
建築物の複数の階床の各々において、乗場が設けられる。乗場において、乗場ドアが設けられる。乗場ドアは、乗場と昇降路とを空間的に分離することによって利用者などが昇降路へ転落することを防止する。乗場ドアは、乗場が設けられる階床に停止しているかごに利用者が乗降しうるように、かごドアの開閉に連動して開閉する機器である。乗場ドアは、エレベーターのドア1の例である。
A landing will be provided on each of the multiple floors of the building. At the landing, a landing door will be provided. The landing door spatially separates the landing and the hoistway to prevent users from falling into the hoistway. The landing door is a device that opens and closes in conjunction with the opening and closing of the car door so that the user can get on and off the car stopped on the floor where the landing is provided. The landing door is an example of the elevator door 1.
以下において、次のように設定されるxyz直交座標系を用いて説明する。y軸の方向は、鉛直方向である。xz平面は、水平面である。z軸の方向は、ドア1の開閉方向である。エレベーターのドア1においてx軸の正の方向は、ドア1が閉じているときに乗客がいる方向である。すなわち、ドア1が乗場ドアである場合に、x軸の正の方向は、乗場を向く方向である。あるいは、ドア1がかごドアである場合に、x軸の正の方向は、かごの内側を向く方向である。
In the following, it will be described using the xyz Cartesian coordinate system set as follows. The direction of the y-axis is the vertical direction. The xz plane is a horizontal plane. The direction of the z-axis is the opening / closing direction of the door 1. The positive direction of the x-axis of the elevator door 1 is the direction in which passengers are present when the door 1 is closed. That is, when the door 1 is a landing door, the positive direction of the x-axis is the direction facing the landing. Alternatively, when the door 1 is a car door, the positive direction of the x-axis is the direction toward the inside of the car.
ドア1は、2枚のドアパネル2と、ドアハンガー3と、敷居4と、を備える。2枚のドアパネル2の各々は、板状の機器である。2枚のドアパネル2の各々の厚さ方向は、x軸の方向に向けられる。2枚のドアパネル2は、ドア1が開閉するときにz軸の方向に移動することで開閉する機器である。すなわち、ドアパネル2の開閉方向は、ドア1の開閉方向である。ドア1が開閉するときに、2枚のドアパネル2は、互いに同じ方向に移動する。ドアハンガー3は、ドア1の上部に設けられる。ドアハンガー3は、ドアパネル2の開閉方向に長い。ドアハンガー3は、各々の上端部がかかっている2枚のドアハンガー3の荷重を支持する。敷居4は、ドアパネル2の下端部より下方に設けられる。敷居4は、ドアパネル2の開閉方向に長い。敷居4は、敷居溝5を有する。敷居溝5は、ドアパネル2の開閉方向に長い溝である。敷居溝5は、ドアパネル2が開閉するときにドアパネル2を案内する溝である。
Door 1 includes two door panels 2, a door hanger 3, and a threshold 4. Each of the two door panels 2 is a plate-shaped device. The thickness direction of each of the two door panels 2 is oriented in the x-axis direction. The two door panels 2 are devices that open and close by moving in the z-axis direction when the door 1 opens and closes. That is, the opening / closing direction of the door panel 2 is the opening / closing direction of the door 1. When the door 1 opens and closes, the two door panels 2 move in the same direction as each other. The door hanger 3 is provided on the upper part of the door 1. The door hanger 3 is long in the opening / closing direction of the door panel 2. The door hanger 3 supports the load of the two door hangers 3 on which the upper ends of the door hangers 3 are applied. The sill 4 is provided below the lower end of the door panel 2. The threshold 4 is long in the opening / closing direction of the door panel 2. The sill 4 has a sill groove 5. The threshold groove 5 is a groove long in the opening / closing direction of the door panel 2. The threshold groove 5 is a groove that guides the door panel 2 when the door panel 2 opens and closes.
図1において、ドアパネル2が全閉している状態のドア1が示される。ドアパネル2が全閉しているときに、ドアパネル2は戸当たり6に当たっている。例えばドア1が乗場ドアである場合に、戸当たり6は、乗場の三方枠に設けられる。あるいは、例えばドア1がかごドアである場合に、戸当たり6は、かごに設けられる。
FIG. 1 shows the door 1 in a state where the door panel 2 is fully closed. When the door panel 2 is fully closed, the door panel 2 hits 6 per door. For example, when the door 1 is a landing door, the door stop 6 is provided in the three-sided frame of the landing. Alternatively, for example, when the door 1 is a car door, the door stop 6 is provided in the car.
ドア1は、隙間遮蔽部7を備える。隙間遮蔽部7は、ドアシュー8と、敷居溝カバー9と、を備える。ここで、隙間遮蔽部7の一部または全部は、保守作業などにおいて交換可能であってもよい。隙間遮蔽部7は、エレベーターのドア1の保守部品の例である。
The door 1 is provided with a gap shielding portion 7. The gap shielding portion 7 includes a door shoe 8 and a sill groove cover 9. Here, a part or all of the gap shielding portion 7 may be replaceable in maintenance work or the like. The gap shielding portion 7 is an example of maintenance parts for the elevator door 1.

The door shoe 8 is provided at the lower end of each of the two door panels 2. The door shoe 8 includes a fixture 10 and a sliding portion 11.
取付具10は、ドアパネル2の下端部に設けられる。取付具10は、例えばネジなどによってドアパネル2に取り付けられる単一の金属板である。ドアパネル2の開閉方向における取付具10の長さは、当該取付具10が取り付けられているドアパネル2の全体にわたる。すなわち、取付具10のz軸方向の長さは、ドアパネル2のz軸方向の幅である。
The fixture 10 is provided at the lower end of the door panel 2. The fixture 10 is a single metal plate that is attached to the door panel 2 with, for example, screws. The length of the fixture 10 in the opening / closing direction of the door panel 2 extends over the entire door panel 2 to which the fixture 10 is attached. That is, the length of the fixture 10 in the z-axis direction is the width of the door panel 2 in the z-axis direction.
摺動部11は、敷居溝5に上方から挿し込まれるように配置される部分である。摺動部11は、例えば樹脂によって形成される。摺動部11の下端は、敷居溝5の上端より下方に配置される。摺動部11の下面は、敷居溝5の底面5bに対向する。摺動部11の側面は、敷居溝5の側壁5aに対向する。摺動部11は、取付具10の下端に接着されている。摺動部11は、取付具10を介してドアパネル2に取り付けられる。なお、摺動部11のz軸方向の長さは、ドアパネル2のz軸方向の幅より短くてもよい。ドアシュー8は、複数の摺動部11を有していてもよい。
The sliding portion 11 is a portion arranged so as to be inserted into the threshold groove 5 from above. The sliding portion 11 is formed of, for example, a resin. The lower end of the sliding portion 11 is arranged below the upper end of the threshold groove 5. The lower surface of the sliding portion 11 faces the bottom surface 5b of the threshold groove 5. The side surface of the sliding portion 11 faces the side wall 5a of the threshold groove 5. The sliding portion 11 is adhered to the lower end of the fixture 10. The sliding portion 11 is attached to the door panel 2 via the attachment 10. The length of the sliding portion 11 in the z-axis direction may be shorter than the width of the door panel 2 in the z-axis direction. The door shoe 8 may have a plurality of sliding portions 11.
敷居溝カバー9は、敷居4に配置される。敷居溝カバー9は、敷居溝5を上方から覆う。敷居溝カバー9は、ドアパネル2の開閉方向に長い器具である。敷居溝カバー9は、可撓性を有する材質によって形成される。敷居溝カバー9は、例えばゴムなどの弾性材料によって形成される。敷居溝カバー9は、スリット12を有する。スリット12は、敷居溝5に沿うように設けられる。

FIG. 2 shows a
この例において、敷居溝カバー9は、敷居4の上面の全体を上方から覆う。敷居溝カバー9は、第1カバー13aおよび第2カバー13bからなる。第1カバー13aは、敷居溝カバー9のx軸方向の正側の部分である。第2カバー13bは、敷居溝カバー9のx軸方向の負側の部分である。第1カバー13aおよび第2カバー13bは、敷居溝5の中心線を通る鉛直面に関して対称に配置される。第1カバー13aおよび第2カバー13bは、敷居溝5の上方において対向する。敷居溝カバー9は、第1カバー13aおよび第2カバー13bの隙間によってスリット12を形成する。すなわち、第2カバー13bに対向する第1カバー13aの端部、および第1カバー13aに対向する第2カバー13bの端部は、スリット12の縁14をなす。スリット12の縁14は、上方に向かって曲がっている。ドアパネル2が全閉しているときに、スリット12の縁14は、弾性などによって上方から下方に押し付けるように取付具10に接触している。
In this example, the sill groove cover 9 covers the entire upper surface of the sill 4 from above. The sill groove cover 9 includes a first cover 13a and a second cover 13b. The first cover 13a is a portion of the threshold groove cover 9 on the positive side in the x-axis direction. The second cover 13b is a portion of the threshold groove cover 9 on the negative side in the x-axis direction. The first cover 13a and the second cover 13b are arranged symmetrically with respect to the vertical plane passing through the center line of the threshold groove 5. The first cover 13a and the second cover 13b face each other above the threshold groove 5. The sill groove cover 9 forms a slit 12 by the gap between the first cover 13a and the second cover 13b. That is, the end of the first cover 13a facing the second cover 13b and the end of the second cover 13b facing the first cover 13a form the edge 14 of the slit 12. The edge 14 of the slit 12 is bent upward. When the door panel 2 is fully closed, the edge 14 of the slit 12 is in contact with the fixture 10 so as to be pressed from above to below by elasticity or the like.
このように、隙間遮蔽部7は、ドアパネル2の下端および敷居4の間の隙間を塞いでいる。ここで、取付具10および敷居溝カバー9は互いに密着している。このため、ドアパネル2の下端部より下方において、ドアパネル2の厚さ方向における気体の流れが遮断される。
In this way, the gap shielding portion 7 closes the gap between the lower end of the door panel 2 and the threshold 4. Here, the fixture 10 and the sill groove cover 9 are in close contact with each other. Therefore, below the lower end of the door panel 2, the flow of gas in the thickness direction of the door panel 2 is blocked.
続いて、図3および図4を用いて、隙間遮蔽部7の動作の例を説明する。
図3は、実施の形態1に係るエレベーターのドアの背面図である。図4は、実施の形態1に係る敷居溝カバーの斜視図である。 Subsequently, an example of the operation of thegap shielding portion 7 will be described with reference to FIGS. 3 and 4.

FIG. 3 is a rear view of the elevator door according to the first embodiment. FIG. 4 is a perspective view of the threshold groove cover according to the first embodiment.
図3において、ドアパネル2が開くときのドア1が示される。このとき、ドアパネル2は、戸当たり6から離れる方向に移動する。摺動部11は、敷居溝5に案内されながら移動する。敷居溝カバー9に接触している取付具10は、スリット12の縁14に接触しながら戸当たり6から離れる方向に移動する。
In FIG. 3, the door 1 when the door panel 2 is opened is shown. At this time, the door panel 2 moves away from the door stop 6. The sliding portion 11 moves while being guided by the threshold groove 5. The fixture 10 in contact with the sill groove cover 9 moves in a direction away from the door stop 6 while in contact with the edge 14 of the slit 12.
図4において、ドアパネル2が全開しているときの隙間遮蔽部7の敷居溝カバー9が示される。敷居溝カバー9のスリット12の縁14は、弾性などによって上方から下方に押し付けるように反対側の縁14に接触している。このとき、スリット12が閉じている。
FIG. 4 shows the sill groove cover 9 of the gap shielding portion 7 when the door panel 2 is fully opened. The edge 14 of the slit 12 of the sill groove cover 9 is in contact with the opposite edge 14 so as to be pressed from above to below by elasticity or the like. At this time, the slit 12 is closed.
一方、ドアパネル2が閉じるときに、ドアパネル2は、戸当たり6に近づく方向に移動する。このとき、摺動部11は、敷居溝5に案内されながら移動する。敷居溝カバー9に接触している取付具10は、スリット12の縁14に接触しながら戸当たり6に近づく方向に移動する。
On the other hand, when the door panel 2 closes, the door panel 2 moves in the direction approaching the door stop 6. At this time, the sliding portion 11 moves while being guided by the threshold groove 5. The fixture 10 in contact with the sill groove cover 9 moves in a direction approaching the door stop 6 while in contact with the edge 14 of the slit 12.
その後、ドアパネル2が全閉するときに、スリット12の縁14は、取付具10に再び接触する。これにより、隙間遮蔽部7は、ドアパネル2の下端および敷居4の間の隙間を塞ぐ。
After that, when the door panel 2 is fully closed, the edge 14 of the slit 12 comes into contact with the fixture 10 again. As a result, the gap shielding portion 7 closes the gap between the lower end of the door panel 2 and the threshold 4.
以上に説明したように、実施の形態1に係るエレベーターのドア1は、隙間遮蔽部7を備える。隙間遮蔽部7は、ドアパネル2が全開しているときに敷居4の敷居溝5を上方から覆う。隙間遮蔽部7は、ドアパネル2が全閉しているときにドアパネル2の下端および敷居4の間の隙間を塞ぐ。
As described above, the elevator door 1 according to the first embodiment includes a gap shielding portion 7. The gap shielding portion 7 covers the sill groove 5 of the sill 4 from above when the door panel 2 is fully open. The gap shielding portion 7 closes the gap between the lower end of the door panel 2 and the threshold 4 when the door panel 2 is fully closed.
敷居溝5への侵入する異物は、例えば乗降する利用者の履物に付着していた小石などである。このため、異物の浸入は、ドアパネル2が全開しているときに起こりやすい。このとき、隙間遮蔽部7は敷居溝5を上方から覆っているので、敷居溝5への異物の侵入を防ぐことができる。また、例えば法規制または防災上の理由などによって、昇降路の防火区画に遮煙性能を有する防火設備が必要になる場合がある。遮煙性能は、例えば、建築物に火災などが発生する場合にドアパネル2が全閉しているときに昇降路および乗場の間において煙を遮断する性能である。ここで、ドアパネル2が全閉しているときに隙間遮蔽部7はドアパネル2の下端および敷居4の間の隙間を塞ぐので、エレベーターのドア1そのものが遮煙性能を持つことができる。これにより、エレベーターのドア1は、敷居溝5への異物の侵入の防止およびドア1の下部における遮煙を両立できる。
The foreign matter that invades the threshold groove 5 is, for example, pebbles attached to the footwear of the user getting on and off. Therefore, foreign matter is likely to enter when the door panel 2 is fully open. At this time, since the gap shielding portion 7 covers the threshold groove 5 from above, it is possible to prevent foreign matter from entering the threshold groove 5. In addition, for example, due to legal regulations or disaster prevention reasons, fire prevention equipment having smoke shielding performance may be required in the fire prevention section of the hoistway. The smoke shielding performance is, for example, a performance of blocking smoke between the hoistway and the landing when the door panel 2 is fully closed when a fire or the like occurs in a building. Here, when the door panel 2 is fully closed, the gap shielding portion 7 closes the gap between the lower end of the door panel 2 and the threshold 4, so that the elevator door 1 itself can have smoke shielding performance. As a result, the door 1 of the elevator can both prevent foreign matter from entering the threshold groove 5 and block smoke at the lower part of the door 1.
また、隙間遮蔽部7は、ドアシュー8と、敷居溝カバー9と、を備える。ドアシュー8は、摺動部11、および取付具10を有する。摺動部11は、ドアパネル2が開閉するときに敷居溝5の内側において敷居溝5に案内される。取付具10は、摺動部11をドアパネル2の下端に取り付ける。取付具10の長さは、ドアパネル2の全体にわたる長さである。敷居溝カバー9は、スリット12を有する。ドアパネル2が開閉するときに、取付具10は、移動しながらスリット12の縁14に接触する。ドアパネル2が全開しているときに、スリット12は閉じる。ドアパネル2が全閉しているときに、スリット12の縁14は、取付具10に接触する。
Further, the gap shielding portion 7 includes a door shoe 8 and a sill groove cover 9. The door shoe 8 has a sliding portion 11 and a fixture 10. The sliding portion 11 is guided to the sill groove 5 inside the sill groove 5 when the door panel 2 opens and closes. The fixture 10 attaches the sliding portion 11 to the lower end of the door panel 2. The length of the fixture 10 is the overall length of the door panel 2. The sill groove cover 9 has a slit 12. When the door panel 2 opens and closes, the fixture 10 comes into contact with the edge 14 of the slit 12 while moving. The slit 12 closes when the door panel 2 is fully open. When the door panel 2 is fully closed, the edge 14 of the slit 12 comes into contact with the fixture 10.
取付具10の長さがドアパネル2の幅の全体にわたる長さであるので、ドアパネル2が全閉しているときにドアパネル2の下端および敷居4の間の隙間が取付具10によって塞がれる。すなわち、隙間遮蔽部7は、取付具10とスリット12の縁14との接触によって、ドアパネル2の下端および敷居4の間の隙間を塞ぐ。これにより、ドアパネル2の下端部より下方において、ドアパネル2の厚さ方向における気体の流れが遮断される。このため、エレベーターのドア1そのものによってドア1の下部において煙の流れを遮断できる。
Since the length of the fixture 10 is the length over the entire width of the door panel 2, the gap between the lower end of the door panel 2 and the sill 4 is closed by the fixture 10 when the door panel 2 is fully closed. That is, the gap shielding portion 7 closes the gap between the lower end of the door panel 2 and the sill 4 by the contact between the fixture 10 and the edge 14 of the slit 12. As a result, the flow of gas in the thickness direction of the door panel 2 is blocked below the lower end of the door panel 2. Therefore, the elevator door 1 itself can block the flow of smoke at the lower part of the door 1.
また、敷居溝カバー9は、敷居4を上方から覆う。これにより、敷居溝カバー9の敷居4への設置が容易になる。
Further, the sill groove cover 9 covers the sill 4 from above. This facilitates the installation of the sill groove cover 9 on the sill 4.
なお、エレベーターのドア1は、ドアパネル2を3枚以上備えていてもよい。エレベーターのドア1は、ドアパネル2を1枚そなえる1枚戸のドアであってもよい。エレベーターのドア1は、開閉するときにドアパネル2が互いに反対方向に移動する両開きのドアであってもよい。
The elevator door 1 may be provided with three or more door panels 2. The elevator door 1 may be a single door having one door panel 2. The elevator door 1 may be a double door in which the door panels 2 move in opposite directions when opening and closing.
また、敷居溝カバー9のスリット12の縁14の形状は、直線状でなくてもよい。スリット12の縁14の形状は、例えば蛇腹、円弧、または三角形などであってもよい。敷居溝カバー9のスリット12の縁14は、下方から上方に押し付けるように反対側の縁14に接触してもよい。あるいは、敷居溝カバー9のスリット12の縁14は、互いに水平方向に押しあうように反対側の縁14に接触してもよい。
Further, the shape of the edge 14 of the slit 12 of the threshold groove cover 9 does not have to be linear. The shape of the edge 14 of the slit 12 may be, for example, a bellows, an arc, or a triangle. The edge 14 of the slit 12 of the sill groove cover 9 may come into contact with the opposite edge 14 so as to be pressed from below to above. Alternatively, the edge 14 of the slit 12 of the threshold groove cover 9 may come into contact with the opposite edge 14 so as to press each other in the horizontal direction.
また、取付具10を形成する材料は、金属でなくてもよい。取付具10は、樹脂材料などによって形成されていてもよい。また、取付具10は、ドアパネル2の下端部と敷居4との間の隙間を塞ぐことによって気体の流れを遮断するものであれば、単一の板でなくてもよい。取付具10は、例えば複数の板状部材などを組み合わせて形成されていてもよい。
Further, the material forming the fixture 10 does not have to be metal. The fixture 10 may be made of a resin material or the like. Further, the fixture 10 does not have to be a single plate as long as it blocks the flow of gas by closing the gap between the lower end of the door panel 2 and the threshold 4. The fixture 10 may be formed by combining, for example, a plurality of plate-shaped members.
また、敷居溝カバー9は、第1カバー13aおよび第2カバー13bに分割されなくてもよい。敷居溝カバー9は、戸当たり6の反対側の端部などにおいて接続している単一の部材であってもよい。
Further, the threshold groove cover 9 does not have to be divided into the first cover 13a and the second cover 13b. The sill groove cover 9 may be a single member connected at the opposite end of the door stop 6.
続いて、図5を用いて、実施の形態1の変形例を説明する。
図5は、実施の形態1の変形例に係る隙間遮蔽部の斜視図である。 Subsequently, a modified example of the first embodiment will be described with reference to FIG.
FIG. 5 is a perspective view of the gap shielding portion according to the modified example of the first embodiment.
図5は、実施の形態1の変形例に係る隙間遮蔽部の斜視図である。 Subsequently, a modified example of the first embodiment will be described with reference to FIG.
FIG. 5 is a perspective view of the gap shielding portion according to the modified example of the first embodiment.
第2カバー13bは、スリット12の反対側の端部に外れ止め部15を有する。この例において、外れ止め部15は、敷居4の上面から側面にかかる部分である。この例において、敷居4は、側面に軒部16を有する。軒部16は、敷居4の上面から側方に張り出す部分である。このとき、外れ止め部15は、軒部16の下面にかかるように設けられてもよい。あるいは、外れ止め部15は、敷居4の下面にかかるように設けられてもよい。外れ止め部15によって、敷居溝カバー9は、敷居4から脱落しにくくなる。
The second cover 13b has a retaining portion 15 at the end opposite to the slit 12. In this example, the retaining portion 15 is a portion extending from the upper surface to the side surface of the sill 4. In this example, the sill 4 has an eaves 16 on its side. The eaves portion 16 is a portion that projects laterally from the upper surface of the threshold 4. At this time, the retaining portion 15 may be provided so as to cover the lower surface of the eaves portion 16. Alternatively, the retaining portion 15 may be provided so as to cover the lower surface of the sill 4. The retaining portion 15 makes it difficult for the sill groove cover 9 to fall off from the sill 4.
敷居溝カバー9は、水平固定部17を有する。水平固定部17は、スリット12の縁14の下方に設けられる。この例において、水平固定部17は、第1カバー13aおよび第2カバー13bに設けられる。水平固定部17は、敷居溝5の側壁5aの上端部に接触する部分である。スリット12の縁14の下方の水平固定部17は、反対側のスリット12の下方の水平固定部17に対向する。両側のスリット12の縁14の下方の水平固定部17の間隔は、取付具10の厚さより広い。水平固定部17によって、敷居溝カバー9のスリット12の位置は、敷居溝5に対して移動しにくくなる。これにより、取付具10の移動に引きずられてスリット12が大きく開くことが防止される。
The sill groove cover 9 has a horizontal fixing portion 17. The horizontal fixing portion 17 is provided below the edge 14 of the slit 12. In this example, the horizontal fixing portion 17 is provided on the first cover 13a and the second cover 13b. The horizontal fixing portion 17 is a portion that contacts the upper end portion of the side wall 5a of the threshold groove 5. The horizontal fixing portion 17 below the edge 14 of the slit 12 faces the horizontal fixing portion 17 below the slit 12 on the opposite side. The distance between the horizontal fixing portions 17 below the edges 14 of the slits 12 on both sides is wider than the thickness of the fixture 10. The horizontal fixing portion 17 makes it difficult for the position of the slit 12 of the sill groove cover 9 to move with respect to the sill groove 5. This prevents the slit 12 from being wide open due to being dragged by the movement of the fixture 10.
なお、外れ止め部15は、敷居溝カバー9の端部を固定するものであればよい。外れ止め部15は、例えば接着剤による敷居溝カバー9および敷居4の間の接着部であってもよい。外れ止め部15は、例えばネジなどによる敷居溝カバー9および敷居4の間の締結部であってもよい。外れ止め部15は、第1カバー13aおよび第2カバー13bの両方または一方に設けられてもよい。
The retaining portion 15 may be any one that fixes the end portion of the sill groove cover 9. The retaining portion 15 may be, for example, an adhesive portion between the sill groove cover 9 and the sill 4 made of an adhesive. The retaining portion 15 may be a fastening portion between the sill groove cover 9 and the sill 4 with screws or the like. The retaining portion 15 may be provided on both or one of the first cover 13a and the second cover 13b.

図6は、実施の形態2に係るエレベーターのドアの背面図である。
FIG. 6 is a rear view of the elevator door according to the second embodiment.
図6において、ドアパネル2が全閉している状態のドア1が示される。ドア1は、隙間遮蔽部7を備える。隙間遮蔽部7は、ドアシュー8と、敷居溝カバー9と、を備える。ここで、隙間遮蔽部7の一部または全部は、保守作業などにおいて交換可能であってもよい。隙間遮蔽部7の一部または全部は、エレベーターのドア1の保守部品の例である。例えば、ドアシュー8または敷居溝カバー9の各々は、保守部品の例である。
FIG. 6 shows the door 1 in a state where the door panel 2 is fully closed. The door 1 includes a gap shielding portion 7. The gap shielding portion 7 includes a door shoe 8 and a sill groove cover 9. Here, a part or all of the gap shielding portion 7 may be replaceable in maintenance work or the like. Part or all of the gap shielding portion 7 is an example of maintenance parts for the elevator door 1. For example, each of the door shoe 8 or the sill groove cover 9 is an example of a maintenance part.
この例において、隙間遮蔽部7は、2つのドアシュー8を備える。2つのドアシュー8の各々は、ドアパネル2の下端部に設けられる。2つのドアシュー8の各々は、取付具10と、摺動部11と、を備える。取付具10のz軸方向の長さは、ドアパネル2のz軸方向の幅より短くてもよい。
In this example, the gap shielding portion 7 includes two door shoes 8. Each of the two door shoes 8 is provided at the lower end of the door panel 2. Each of the two door shoes 8 includes a fixture 10 and a sliding portion 11. The length of the fixture 10 in the z-axis direction may be shorter than the width of the door panel 2 in the z-axis direction.
敷居溝カバー9は、突起部18を有する。突起部18は、スリット12の縁14の下方に設けられる。この例において、敷居溝カバー9は、複数の突起部18を有する。突起部18は、ドアシュー8の摺動部11のいずれかに対応する。突起部18は、対応する摺動部11のドアパネル2が全閉しているときの位置に設けられる。突起部18は、傾斜部18aを有する。傾斜部18aは、突起部18の裾野部分18cから突起部18の頂部分18bに向かって傾斜している部分である。突起部18の裾野部分18cは、ドアパネル2の開閉方向における突起部18の端部である。突起部18の頂部分18bは、ドアパネル2の開閉方向において周囲より大きく突出している部分である。突起部18の頂部分18bは、平坦な部分を有していてもよい。突起部18の頂部分18bは、対応する摺動部11のドアパネル2が全閉しているときの位置に設けられる。ドアパネル2の開閉方向における突起部18の長さは、ドアパネル2が全閉しているときに摺動部11に接触しない長さである。
The sill groove cover 9 has a protrusion 18. The protrusion 18 is provided below the edge 14 of the slit 12. In this example, the sill groove cover 9 has a plurality of protrusions 18. The protrusion 18 corresponds to any of the sliding portions 11 of the door shoe 8. The protrusion 18 is provided at a position when the door panel 2 of the corresponding sliding portion 11 is fully closed. The protrusion 18 has an inclined portion 18a. The inclined portion 18a is a portion that is inclined from the skirt portion 18c of the protruding portion 18 toward the top portion 18b of the protruding portion 18. The skirt portion 18c of the protrusion 18 is an end of the protrusion 18 in the opening / closing direction of the door panel 2. The top portion 18b of the protrusion 18 is a portion that protrudes more than the periphery in the opening / closing direction of the door panel 2. The top portion 18b of the protrusion 18 may have a flat portion. The top portion 18b of the protrusion 18 is provided at a position when the door panel 2 of the corresponding sliding portion 11 is fully closed. The length of the protrusion 18 in the opening / closing direction of the door panel 2 is a length that does not come into contact with the sliding portion 11 when the door panel 2 is fully closed.
図7は、実施の形態2に係る隙間遮蔽部の鉛直断面図である。
図7は、図6におけるA-A断面図である。 FIG. 7 is a vertical cross-sectional view of the gap shielding portion according to the second embodiment.
FIG. 7 is a cross-sectional view taken along the line AA in FIG.
図7は、図6におけるA-A断面図である。 FIG. 7 is a vertical cross-sectional view of the gap shielding portion according to the second embodiment.
FIG. 7 is a cross-sectional view taken along the line AA in FIG.
図7において、ドアパネル2が全閉しているときの隙間遮蔽部7が示される。突起部18は、スリット12の両側の縁14の下方に設けられる。この例において、突起部18は、第1カバー13aにおけるスリット12の縁14の下方、および第2カバー13bにおけるスリット12の縁14の下方の両方に設けられる。突起部18は、対応する摺動部11の上面に乗り上げている。突起部18は、摺動部11に押し上げられている。これにより、スリット12の縁14は、ドアパネル2の下端まで持ち上げられる。
FIG. 7 shows the gap shielding portion 7 when the door panel 2 is fully closed. The protrusions 18 are provided below the edges 14 on both sides of the slit 12. In this example, the protrusions 18 are provided both below the edge 14 of the slit 12 on the first cover 13a and below the edge 14 of the slit 12 on the second cover 13b. The protrusion 18 rides on the upper surface of the corresponding sliding portion 11. The protrusion 18 is pushed up by the sliding portion 11. As a result, the edge 14 of the slit 12 is lifted to the lower end of the door panel 2.
このように、隙間遮蔽部7は、ドアパネル2の下端および敷居4の間の隙間を塞いでいる。この例において、取付具10および敷居溝カバー9は互いに密着している。このため、ドアパネル2の下端部より下方において、ドアパネル2の厚さ方向における気体の流れが遮断される。なお、隙間遮蔽部7がドアパネル2の下端および敷居4の間の隙間を塞いでいれば、取付具10および敷居溝カバー9は必ずしも互いに密着していなくてもよい。
In this way, the gap shielding portion 7 closes the gap between the lower end of the door panel 2 and the threshold 4. In this example, the fixture 10 and the sill groove cover 9 are in close contact with each other. Therefore, below the lower end of the door panel 2, the flow of gas in the thickness direction of the door panel 2 is blocked. If the gap shielding portion 7 closes the gap between the lower end of the door panel 2 and the sill 4, the fixture 10 and the sill groove cover 9 do not necessarily have to be in close contact with each other.
続いて、図8および図9を用いて、隙間遮蔽部7の動作の例を説明する。
図8は、実施の形態2に係るエレベーターのドアの背面図である。図9は、実施の形態2に係る敷居溝カバーの鉛直断面図である。 Subsequently, an example of the operation of thegap shielding portion 7 will be described with reference to FIGS. 8 and 9.
FIG. 8 is a rear view of the elevator door according to the second embodiment. FIG. 9 is a vertical cross-sectional view of the sill groove cover according to the second embodiment.
図8は、実施の形態2に係るエレベーターのドアの背面図である。図9は、実施の形態2に係る敷居溝カバーの鉛直断面図である。 Subsequently, an example of the operation of the
FIG. 8 is a rear view of the elevator door according to the second embodiment. FIG. 9 is a vertical cross-sectional view of the sill groove cover according to the second embodiment.
図8において、ドアパネル2が開くときのドア1が示される。このとき、ドアパネル2は、戸当たり6から離れる方向に移動する。摺動部11は、敷居溝5に案内されながら移動する。敷居溝カバー9に接触している取付具10は、スリット12の縁14に接触しながら戸当たり6から離れる方向に移動する。
In FIG. 8, the door 1 when the door panel 2 is opened is shown. At this time, the door panel 2 moves away from the door stop 6. The sliding portion 11 moves while being guided by the threshold groove 5. The fixture 10 in contact with the sill groove cover 9 moves in a direction away from the door stop 6 while in contact with the edge 14 of the slit 12.
ドアシュー8の摺動部11は、敷居溝カバー9の突起部18の下方から移動する。これにより、摺動部11に接触していない突起部18は、下方に下がる。このとき、突起部18の頂部分18bは、摺動部11の上面の高さより下方まで下がる。スリット12の縁14は、突起部18とともにドアパネル2の下端の高さより下方まで下がる。
The sliding portion 11 of the door shoe 8 moves from below the protrusion 18 of the sill groove cover 9. As a result, the protrusion 18 that is not in contact with the sliding portion 11 is lowered. At this time, the top portion 18b of the protrusion 18 is lowered below the height of the upper surface of the sliding portion 11. The edge 14 of the slit 12 is lowered together with the protrusion 18 below the height of the lower end of the door panel 2.
図9は、図8におけるB-B断面図である。図9において、ドアパネル2が開くときの隙間遮蔽部7の敷居溝カバー9が示される。敷居溝カバー9のスリット12の縁14は、弾性などによって上方から下方に押し付けるように反対側の縁14に接触している。このとき、スリット12が閉じている。この例において、スリット12の縁14の高さは、敷居溝カバー9の上面の高さよりも下方まで下がる。
FIG. 9 is a cross-sectional view taken along the line BB in FIG. In FIG. 9, the sill groove cover 9 of the gap shielding portion 7 when the door panel 2 is opened is shown. The edge 14 of the slit 12 of the sill groove cover 9 is in contact with the opposite edge 14 so as to be pressed from above to below by elasticity or the like. At this time, the slit 12 is closed. In this example, the height of the edge 14 of the slit 12 is lower than the height of the upper surface of the threshold groove cover 9.
一方、ドアパネル2が閉じるときに、ドアパネル2は、戸当たり6に近づく方向に移動する。このとき、摺動部11は、敷居溝5に案内されながら移動する。敷居溝カバー9に接触している取付具10は、スリット12の縁14に接触しながら戸当たり6に近づく方向に移動する。
On the other hand, when the door panel 2 closes, the door panel 2 moves in the direction approaching the door stop 6. At this time, the sliding portion 11 moves while being guided by the threshold groove 5. The fixture 10 in contact with the sill groove cover 9 moves in a direction approaching the door stop 6 while in contact with the edge 14 of the slit 12.
その後、ドアシュー8の摺動部11は、敷居溝カバー9の突起部18に接触する。ドアパネル2の開閉方向において摺動部11が突起部18に押し当たる力は、突起部18の傾斜部18aによって突起部18を上方に持ち上げる力に変換される。これにより、突起部18は、上方に押し上げられる。
After that, the sliding portion 11 of the door shoe 8 comes into contact with the protrusion 18 of the threshold groove cover 9. The force with which the sliding portion 11 presses against the protrusion 18 in the opening / closing direction of the door panel 2 is converted into a force for lifting the protrusion 18 upward by the inclined portion 18a of the protrusion 18. As a result, the protrusion 18 is pushed upward.
その後、ドアパネル2が全閉するときに、スリット12の縁14は、ドアパネル2の下端まで再び持ち上げられる。これにより、隙間遮蔽部7は、ドアパネル2の下端および敷居4の間の隙間を塞ぐ。
After that, when the door panel 2 is fully closed, the edge 14 of the slit 12 is lifted up to the lower end of the door panel 2 again. As a result, the gap shielding portion 7 closes the gap between the lower end of the door panel 2 and the threshold 4.
以上に説明したように、実施の形態2に係る隙間遮蔽部7は、ドアシュー8と、敷居溝カバー9と、を備える。ドアシュー8は、摺動部11および取付具10を有する。摺動部11は、ドアパネル2が開閉するときに敷居溝5の内側において敷居溝5に案内される。取付具10は、摺動部11をドアパネル2の下端に取り付ける。敷居溝カバー9は、スリット12を有する。ドアパネル2が開閉するときに、取付具10は、移動しながらスリット12の縁14に接触する。ドアパネル2が全開しているときに、スリット12は閉じる。ドアパネル2が全閉しているときに、スリット12の縁14は、持ち上がってドアパネル2の下端に接触する。
As described above, the gap shielding portion 7 according to the second embodiment includes a door shoe 8 and a sill groove cover 9. The door shoe 8 has a sliding portion 11 and a fixture 10. The sliding portion 11 is guided to the sill groove 5 inside the sill groove 5 when the door panel 2 opens and closes. The fixture 10 attaches the sliding portion 11 to the lower end of the door panel 2. The sill groove cover 9 has a slit 12. When the door panel 2 opens and closes, the fixture 10 comes into contact with the edge 14 of the slit 12 while moving. The slit 12 closes when the door panel 2 is fully open. When the door panel 2 is fully closed, the edge 14 of the slit 12 is lifted and comes into contact with the lower end of the door panel 2.
敷居溝カバー9は、敷居溝5を上方から覆っている。このため、敷居溝カバー9の長さは、ドアパネル2の開閉方向における長さより長い。ドアパネル2が全閉しているときに敷居溝カバー9のスリット12の縁14がドアパネル2の下端まで持ち上がるので、ドアパネル2の下端および敷居4の間の隙間が敷居溝カバー9によって塞がれる。すなわち、隙間遮蔽部7は、持ち上がったスリット12の縁14とドアパネル2の下端との接触によって、ドアパネル2の下端および敷居4の間の隙間を塞ぐ。これにより、ドアパネル2の下端部より下方において、ドアパネル2の厚さ方向における気体の流れが遮断される。このため、エレベーターのドア1そのものによってドア1の下部において煙の流れを遮断できる。
The sill groove cover 9 covers the sill groove 5 from above. Therefore, the length of the sill groove cover 9 is longer than the length of the door panel 2 in the opening / closing direction. When the door panel 2 is fully closed, the edge 14 of the slit 12 of the sill groove cover 9 is lifted to the lower end of the door panel 2, so that the gap between the lower end of the door panel 2 and the sill 4 is closed by the sill groove cover 9. That is, the gap shielding portion 7 closes the gap between the lower end of the door panel 2 and the sill 4 by the contact between the edge 14 of the raised slit 12 and the lower end of the door panel 2. As a result, the flow of gas in the thickness direction of the door panel 2 is blocked below the lower end of the door panel 2. Therefore, the elevator door 1 itself can block the flow of smoke at the lower part of the door 1.
また、敷居溝カバー9は、スリット12の縁14に突起部18を有する。突起部18は、ドアパネル2が全閉しているときに摺動部11に接触する。スリット12の縁14は、突起部18が摺動部11に押し上げられることによってドアパネル2の下端まで持ち上がる。
Further, the sill groove cover 9 has a protrusion 18 on the edge 14 of the slit 12. The protrusion 18 comes into contact with the sliding portion 11 when the door panel 2 is fully closed. The edge 14 of the slit 12 is lifted to the lower end of the door panel 2 by the protrusion 18 being pushed up by the sliding portion 11.
敷居溝カバー9は、ドアパネル2の開閉の動作によってドアパネル2の下端まで持ち上がる。このため、ドアパネル2の全閉に連動して、ドアパネル2の下端と敷居4との間の隙間が塞がれる。また、ドアパネル2の開く動作に連動して、スリット12の縁14が下方に下がる。このため、敷居溝カバー9は、敷居4の上を通過する利用者などの通行の妨げになりにくい。
The sill groove cover 9 is lifted to the lower end of the door panel 2 by the operation of opening and closing the door panel 2. Therefore, in conjunction with the fully closing of the door panel 2, the gap between the lower end of the door panel 2 and the sill 4 is closed. Further, in conjunction with the opening operation of the door panel 2, the edge 14 of the slit 12 is lowered downward. Therefore, the sill groove cover 9 is less likely to obstruct the passage of users and the like passing over the sill 4.
また、突起部18は、傾斜部18aを有する。傾斜部18aは、裾野部分18cから頂部分18bに向かって傾斜している部分である。傾斜部18aによって、開閉方向から摺動部11が突起部18に押し当たる力が、突起部18を上方に押し上げる力に変換される。このため、スリット12の縁14は、ドアパネル2の全閉に連動してスムーズに押し上げられる。
Further, the protrusion 18 has an inclined portion 18a. The inclined portion 18a is a portion inclined from the base portion 18c toward the top portion 18b. The inclined portion 18a converts the force with which the sliding portion 11 presses against the protrusion 18 from the opening / closing direction into a force for pushing the protrusion 18 upward. Therefore, the edge 14 of the slit 12 is smoothly pushed up in conjunction with the fully closing of the door panel 2.
なお、突起部18は、傾斜部18aを有していなくてもよい。突起部18は、スリット12の縁14から垂直に下方に突出する部分であってもよい。このとき、例えば摺動部11が、上面から開閉方向の端部に向けて下がる傾斜を有していてもよい。すなわち、摺動部11が突起部18に押し当たる力は、摺動部11の傾斜によって突起部18を上方に押し上げる力に変換されてもよい。
The protrusion 18 does not have to have the inclined portion 18a. The protrusion 18 may be a portion that protrudes vertically downward from the edge 14 of the slit 12. At this time, for example, the sliding portion 11 may have an inclination that descends from the upper surface toward the end portion in the opening / closing direction. That is, the force that the sliding portion 11 presses against the protrusion 18 may be converted into a force that pushes the protrusion 18 upward due to the inclination of the sliding portion 11.
続いて、図10および図11を用いて、実施の形態2の変形例を説明する。

図10において、ドアパネル2が全閉しているときの隙間遮蔽部7の敷居溝カバー9が示される。敷居溝カバー9は、挿入部19を有する。挿入部19は、敷居溝5に挿入される部分である。ドアパネル2の開閉方向に垂直な平面における挿入部19の断面形状は、例えば敷居溝5の側壁5aおよび底面5bに沿ったコ字状の形状である。挿入部19は、例えば第1カバー13aおよび第2カバー13bを接続する。このとき、挿入部19、第1カバー13aおよび第2カバー13bは、一体に形成されていてもよい。挿入部19は、ドアパネル2の開閉方向において敷居溝カバー9の全長にわたって設けられていてもよい。あるいは、挿入部19は、ドアパネル2の開閉方向において敷居溝カバー9の一部に設けられていてもよい。挿入部19は、例えば敷居溝カバー9の端部に設けられていてもよい。挿入部19は、敷居溝5の側壁5aまたは底面5bの少なくとも一方に接触する。この例において、挿入部19は、敷居溝5の側壁5aおよび底面5bの両方に接触する。また、挿入部19は、摺動部11の下面と敷居溝5の底面5bとの間に配置される。挿入部19の断面形状は、例えば半長円状または半楕円状などの形状であってもよい。
FIG. 10 shows the sill groove cover 9 of the gap shielding portion 7 when the door panel 2 is fully closed. The sill groove cover 9 has an insertion portion 19. The insertion portion 19 is a portion to be inserted into the threshold groove 5. The cross-sectional shape of the insertion portion 19 in the plane perpendicular to the opening / closing direction of the door panel 2 is, for example, a U-shape along the side wall 5a and the bottom surface 5b of the threshold groove 5. The insertion portion 19 connects, for example, the first cover 13a and the second cover 13b. At this time, the insertion portion 19, the first cover 13a, and the second cover 13b may be integrally formed. The insertion portion 19 may be provided over the entire length of the threshold groove cover 9 in the opening / closing direction of the door panel 2. Alternatively, the insertion portion 19 may be provided in a part of the threshold groove cover 9 in the opening / closing direction of the door panel 2. The insertion portion 19 may be provided, for example, at the end of the threshold groove cover 9. The insertion portion 19 contacts at least one of the side wall 5a or the bottom surface 5b of the threshold groove 5. In this example, the insertion portion 19 contacts both the side wall 5a and the bottom surface 5b of the sill groove 5. Further, the insertion portion 19 is arranged between the lower surface of the sliding portion 11 and the bottom surface 5b of the threshold groove 5. The cross-sectional shape of the insertion portion 19 may be, for example, a semi-oval shape or a semi-elliptical shape.
図11において、ドアパネル2が開くときの隙間遮蔽部7の敷居溝カバー9が示される。敷居溝カバー9のスリット12の縁14は、弾性などによって上方から下方に押し付けるように反対側の縁14に接触している。このとき、スリット12が閉じている。この例において、スリット12の縁14の高さは、敷居溝カバー9の上端の高さよりも下方まで下がる。
In FIG. 11, the sill groove cover 9 of the gap shielding portion 7 when the door panel 2 is opened is shown. The edge 14 of the slit 12 of the sill groove cover 9 is in contact with the opposite edge 14 so as to be pressed from above to below by elasticity or the like. At this time, the slit 12 is closed. In this example, the height of the edge 14 of the slit 12 is lower than the height of the upper end of the threshold groove cover 9.
また、敷居溝カバー9は、挿入部19と敷居溝5の側壁5aまたは底面5bとの接触によって、摩擦力を受ける。摩擦力によって、敷居溝カバー9は、水平方向および鉛直方向に動きにくくなる。
Further, the sill groove cover 9 receives a frictional force due to contact between the insertion portion 19 and the side wall 5a or the bottom surface 5b of the sill groove 5. The frictional force makes it difficult for the threshold groove cover 9 to move in the horizontal direction and the vertical direction.
このように、敷居溝カバー9は、敷居溝5の内側に挿入される。これにより、敷居溝カバー9のスリット12の位置は、敷居溝5に対して移動しにくくなる。また、敷居溝カバー9は、挿入部19と敷居溝5の側壁5aまたは底面5bとの接触によって、鉛直方向に動きにくくなる。これにより、敷居溝カバー9は、例えばネジによる締結、または接着剤による接着などによらずに、敷居溝5に固定される。また、敷居溝カバー9は、摺動部11の下面との接触によって、敷居溝5から鉛直方向に外れにくくなる。
In this way, the sill groove cover 9 is inserted inside the sill groove 5. As a result, the position of the slit 12 of the sill groove cover 9 becomes difficult to move with respect to the sill groove 5. Further, the sill groove cover 9 becomes difficult to move in the vertical direction due to the contact between the insertion portion 19 and the side wall 5a or the bottom surface 5b of the sill groove 5. As a result, the sill groove cover 9 is fixed to the sill groove 5 without being fastened with screws or bonded with an adhesive, for example. Further, the sill groove cover 9 is less likely to come off from the sill groove 5 in the vertical direction due to contact with the lower surface of the sliding portion 11.
なお、敷居溝カバー9は、敷居溝5の底面5bに固定されてもよい。敷居溝カバー9は、例えばネジによって敷居溝5の底面5bに締結されていてもよい。敷居溝カバー9は、例えば接着剤によって敷居溝5の底面5bに接着されていてもよい。これにより、敷居溝カバー9は、より確実に敷居溝5に固定される。
The sill groove cover 9 may be fixed to the bottom surface 5b of the sill groove 5. The sill groove cover 9 may be fastened to the bottom surface 5b of the sill groove 5 with screws, for example. The sill groove cover 9 may be adhered to the bottom surface 5b of the sill groove 5 with, for example, an adhesive. As a result, the sill groove cover 9 is more securely fixed to the sill groove 5.
