Description

本発明は、エレベータの乗りかごの上昇時における該乗りかご内の騒音レベルを低減するエレベータに関する。 The present invention relates to an elevator that reduces the noise level in the elevator car when the elevator car rises.

エレベータの乗りかごが昇降路内を昇降するとき、昇降路内の空気は該昇降路と前記乗りかごとの間を流れる。この際、風路断面積の変化に伴って気流の乱れが発生し、風切り音と称される騒音が生じることがある。このような騒音の発生を軽減するために、前記乗りかごの上部および下部に整風カバーを設けることで、乗りかごの昇降に伴う空気の流れを円滑化することが提唱されている（例えば特許文献１を参照）。 When the elevator car moves up and down in the hoistway, the air in the hoistway flows between the hoistway and the car. At this time, the airflow is disturbed with the change in the cross-sectional area of the air passage, and noise called wind noise may be generated. In order to reduce the occurrence of such noise, it has been proposed to provide a wind regulation cover on the upper and lower parts of the car so as to smooth the air flow accompanying the raising and lowering of the car (for example, Patent Documents). 1).

このような騒音の発生を防ぐために、例えば前記乗りかごの敷居下部に整風部材を設けて該乗りかごの昇降に伴う気流を該乗りかごの側方および後方に導くことが提唱されている（例えば特許文献２を参照）。 In order to prevent the generation of such noise, for example, it has been proposed to provide an air conditioning member at the lower part of the sill of the car to guide the airflow accompanying the raising and lowering of the car to the side and rear of the car (for example, (See Patent Document 2).

ところで前記乗りかごが乗降階に着床したとき、前記乗りかごの敷居と乗場敷居との隙間から物が落ちないように、また車いすや台車の車輪が挟まらないように前記乗りかごの敷居（カーシル）と乗場敷居（ホールシル）との隙間を出来得る限り狭くすることが行われている。この為、前記乗りかごが高速に昇降路内を昇降する際、特に乗場を通過する際、前記乗りかごのドアパネルに沿って流れる空気（走行風）が前記乗りかごの敷居（カーシル）と乗場敷居（ホールシル）との隙間に空気が流れ込む。するとこの隙間に流れ込んだ空気が圧縮され、空気振動に起因する騒音（バフ音）を発生する。 By the way, when the car has landed on the landing floor, the sill of the car (so that the wheel of the wheelchair and the carriage is not pinched, so that no objects fall from the gap between the car sill and the landing sill. The gap between the car sill and the hall sill (hole sill) is made as narrow as possible. For this reason, when the car moves up and down in the hoistway at high speed, especially when passing through the hall, the air (running wind) flowing along the door panel of the car causes the car sill (carsill) and the hall sill Air flows into the gap with (Hall Sil). Then, the air flowing into the gap is compressed, and noise (buffing sound) caused by air vibration is generated.

しかし前述した特許文献１,２にそれぞれ開示される技術は、前記乗りかごの上部および／または下部における空気の流れを整流するだけである。この為、前記乗りかごのドアパネルに沿って流れて前記乗りかごの敷居（カーシル）と乗場敷居（ホールシル）との隙間に流れ込む空気に起因する上記騒音（バフ音）の発生には、十分には対処することができないと言う課題がある。 However, the techniques disclosed in Patent Documents 1 and 2 described above only rectify the air flow in the upper part and / or lower part of the car. For this reason, in order to generate the noise (buff sound) due to the air flowing along the door panel of the car and flowing into the gap between the car sill (car sill) and the landing sill (hall sill) There is a problem that it cannot be dealt with.

本発明はこのような事情を考慮してなされたもので、その目的は、乗りかごの昇降時、特に上昇時における該乗りかご内の騒音レベルを低減することのできるエレベータを提供することにある。 The present invention has been made in consideration of such circumstances, and an object of the present invention is to provide an elevator capable of reducing the noise level in the car when the car is raised and lowered, particularly when the car is raised. .

上述した目的を達成するべく本発明に係るエレベータは、昇降路内を昇降する乗りかご本体と、この乗りかご本体の出入り口を開閉するドアパネルと、このドアパネルの下方に設置された前記乗りかごの敷居と、この敷居に沿って前記ドアパネルの外面側に、この外面との間に溝を形成するように設けられ、この溝の前記ドアパネルの外側の面との対向面は上方に向かって前記敷居の前縁側に傾斜する傾斜面を形成する整風部材と、を備えることを特徴とする。 Elevator according to the present invention in order to achieve the above object, a car body to lift a hoistway, a door panel for opening and closing the entrance of the car body, the threshold of the car placed below the door panel If, on the outer surface side of the front SL door panel along the sill, the sill provided so as to form a groove, the surface facing the outer surface of the door panel of the groove upward between the outer surface And an air conditioning member that forms an inclined surface that is inclined toward the front edge side .

本発明に係るエレベータによれば、前記乗りかごの上昇時にドアパネルに沿って流れる空気を前記整風部材により前記乗りかごの側方に向けて導き、乗りかごの敷居（カーシル）と乗場側の敷居（ホールシル）との隙間に流れ込む風を減少させることができる。この結果、前記ドアパネルに沿って流れる空気に起因する騒音（バフ音）の発生を抑え、以て乗りかご内の騒音レベルを低減することが可能となる。 According to the elevator of the present invention, the air that flows along the door panel when the car is lifted is guided toward the side of the car by the air conditioning member, and the car sill (carsill) and the platform side sill ( The wind flowing into the gap with the hole sill can be reduced. As a result, it is possible to suppress the generation of noise (buffing sound) due to the air flowing along the door panel, thereby reducing the noise level in the car.

以下、図面を参照して本発明の実施形態に係るエレベータについて説明する。 Hereinafter, an elevator according to an embodiment of the present invention will be described with reference to the drawings.

図１はエレベータの概略構成を示す図で、１は建屋における複数の階床にそれぞれ設けられた乗場２に沿う昇降路、３は前記昇降路２内を昇降する乗りかごである。前記乗りかご３は、前記昇降路１の上部の機械室４に設けられた巻上機５に卷装された主索（メインロープ）６の一端側に懸架され、前記昇降路１内に沿直に敷設されたガイドレール７により案内されて前記昇降路１内を昇降する。尚、図中８は前記主索６の他端側に取り付けられた釣合い錘であり、この釣合い錘８は前記昇降路２内に沿直に敷設されたカウンターレール９に案内されて昇降する。 FIG. 1 is a diagram showing a schematic configuration of an elevator, wherein 1 is a hoistway along a hall 2 provided on each of a plurality of floors in a building, and 3 is a car that moves up and down in the hoistway 2. The car 3 is suspended on one end side of a main rope (main rope) 6 mounted on a hoisting machine 5 provided in a machine room 4 in the upper part of the hoistway 1. The hoistway 1 is raised and lowered by being guided by a guide rail 7 laid directly. In the figure, reference numeral 8 denotes a counterweight attached to the other end of the main rope 6. The counterweight 8 is guided by a counter rail 9 laid straight in the hoistway 2 and moves up and down.

前記乗りかご３は、図２に示すように箱形の躯体からなり、その前面に開口された出入口を開閉可能にドアパネル１１を設けて構成される。このドアパネル１１は、前記出入口の上部に設けられたハンガー機構（ドアマシン；図示せず）に懸架され、前記出入口の幅方向にスライド自在に設けられる。尚、図中１２は、前記ハンガー機構を覆うヘッドカバーである。またここでは２枚のドアパネル１１ａ,１１ｂを、前記出入口の一側部に重ねて収納して該出入口を開放する片開き型の乗りかご３を例示するが、いわゆる両開き型のものであっても良い。 As shown in FIG. 2, the car 3 is formed of a box-shaped housing, and is configured by providing a door panel 11 so as to be able to open and close an entrance opened on the front surface thereof. The door panel 11 is suspended by a hanger mechanism (door machine; not shown) provided at the upper part of the doorway, and is slidable in the width direction of the doorway. In the figure, reference numeral 12 denotes a head cover that covers the hanger mechanism. In addition, here, there is illustrated a single-open type car 3 in which two door panels 11a and 11b are accommodated in one side portion of the entrance and opened to open the entrance. good.

ちなみに前記２枚のドアパネル１１ａ,１１ｂは、平行に設けられた２条のレールにそれぞれ懸架されて互いに連動してスライド駆動される。そして前記乗りかご３の前面側に位置付けられた前記ドアパネル（高速ドアパネル）１１ａは、該ドアパネル１１ｂの裏面側に位置付けられた前記ドアパネル（低速ドアパネル）１１ｂよりもスライド幅が長く（略２倍）設定されている。 Incidentally, the two door panels 11a and 11b are respectively suspended on two rails provided in parallel and are slidably driven in conjunction with each other. The door panel (high-speed door panel) 11a positioned on the front side of the car 3 is set to have a longer slide width (substantially twice) than the door panel (low-speed door panel) 11b positioned on the back side of the door panel 11b. Has been.

ここで本発明に係るエレベータが特徴とするところは、前記ドアパネル１１（ドアパネル１１ａ）の前面下部の、前記乗りかご３における前記ドアパネル１１の前面側に突出した敷居（カーシル）１３の近傍に整風部材１４を設けた点にある。この整風部材１４は、前記出入口を塞ぐ前記２枚のドアパネル１１ａ,１１ｂの展開幅と略等しい幅Ｌを有し、前記敷居１３の前縁部に沿って設けられる。 Here, the elevator according to the present invention is characterized in that a wind regulating member is provided in the vicinity of a sill (carsill) 13 projecting to the front side of the door panel 11 in the car 3 at the lower front portion of the door panel 11 (door panel 11a). 14 is provided. The air conditioning member 14 has a width L substantially equal to the developed width of the two door panels 11 a and 11 b that close the entrance and is provided along the front edge of the sill 13.

図３は前記整風部材１４の前記ドアパネル１１に対する取り付け構造を示す側面図である。この図３に示すように前記整風部材１４は前記ドアパネル１１ａへの取り付け面をなす内側面１４ａと、前記敷居１３の前縁部に同一面に位置付けられる沿直な外側面１４ｂと、前記乗りかご３の昇降方向の高さが変化する傾斜面１４ｃとを備えた、断面略三角形状の部材からなる。特に前記傾斜面１４ｃは、前記敷居からの高さが該敷居の前縁側から前記ドアパネルの前面側に向けて低く形成されている。従って前記ドアパネル１１ａの前面に取り付けられた前記整風部材１４は、図３に示すように前記傾斜面１４ｃと該ドアパネル１１（１１ａ,１１ｂ）の前面との間に、上方に向けて拡がる開口部を形成する。 FIG. 3 is a side view showing a structure for attaching the air conditioning member 14 to the door panel 11. As shown in FIG. 3, the air conditioning member 14 includes an inner side surface 14a that forms a mounting surface for the door panel 11a, a straight outer side surface 14b that is positioned on the same surface as the front edge of the sill 13, and the car. 3 and an inclined surface 14c whose height in the ascending / descending direction is changed. Particularly, the inclined surface 14c is formed such that the height from the sill is lowered from the front edge side of the sill toward the front side of the door panel. Therefore, the air conditioning member 14 attached to the front surface of the door panel 11a has an opening that extends upward between the inclined surface 14c and the front surface of the door panel 11 (11a, 11b) as shown in FIG. Form.

尚、図４(ａ)(ｂ)に前記ドアパネル１１（１１ａ,１１ｂ）と前記整風部材１４との平面的な関係を示すように、前記整風部材１４は前記ドアパネル１１ａに固定されて該ドアパネル１１ａと一体にスライドするように設けられる。ちなみに前記ドアパネル１１ａ,１１ｂを展開して前記乗りかご３の出入口を塞いだときには、前記整風部材１４は該出入口の前方に位置付けられる。このとき、前記ドアパネル１１ａの前面に固定された前記整風部材１４の該ドアパネル１１ａから突出した部分は、該ドアパネル１１ａの厚み分を隔てて前記ドアパネル１１ｂの前面に対向配置される。 4A and 4B, the air conditioning member 14 is fixed to the door panel 11a so as to show a planar relationship between the door panel 11 (11a, 11b) and the air conditioning member 14. And so as to slide together. Incidentally, when the door panels 11a and 11b are deployed to close the entrance / exit of the car 3, the air conditioning member 14 is positioned in front of the entrance / exit. At this time, a portion of the air conditioning member 14 fixed to the front surface of the door panel 11a that protrudes from the door panel 11a is opposed to the front surface of the door panel 11b with a thickness of the door panel 11a.

そして前記ドアパネル１１ａ,１１ｂを幅方向にスライドさせて前記乗りかご３の出入口の一側部に重ねて収納し、これによって前記出入口を開放したときには、前記整風部材１４は前記出入口を避けた前記ドアパネル１１ａ,１１ｂの収納位置に位置付けられる。従って前記整風部材１４は、前記出入口を介する前記乗りかご３への乗降の邪魔になることがない。但し、この場合、図４(ｂ)に示すように、前記整風部材１４の一端部が前記乗りかご３の側部から突出することが否めない。 Then, the door panels 11a and 11b are slid in the width direction so as to be stacked and housed on one side of the entrance / exit of the car 3, so that when the entrance / exit is opened, the air conditioning member 14 avoids the entrance / exit. It is positioned at the storage position of 11a, 11b. Therefore, the air conditioning member 14 does not interfere with getting on and off the car 3 through the doorway. However, in this case, as shown in FIG. 4B, it cannot be denied that one end portion of the air conditioning member 14 protrudes from the side portion of the car 3.

尚、前記整風部材１４の厚み（前記内側面１４ａと外側面１４ｂとの距離）Ｄについては、前記乗りかご３の敷居（カーシル）１３の前縁部と、前記乗場側の前記昇降路１内に突出した敷居（ホールシル）２ａの前端部との隙間Ｗ（一般的には１０ｍｍ程度）よりも大きいことが望ましい。しかし前記乗りかご３の敷居１３の前縁部の前記ドアパネル１１ａの前面からの突出長が前記隙間Ｗよりも短い場合には、前記整風部材１４の外側面１４ｂが前記乗りかご３の敷居１３の前縁部から突出しない程度に該整風部材１４の厚みＤを定めれば十分である。 In addition, about the thickness (distance of the said inner surface 14a and the outer surface 14b) D of the said air conditioning member 14, the front edge part of the sill (carsill) 13 of the said cage | basket | car 3 and the said hoistway 1 in the said platform side It is desirable that it is larger than the gap W (generally about 10 mm) with the front end portion of the sill (hole sill) 2a protruding in the middle. However, when the protruding length of the front edge portion of the sill 13 of the car 3 from the front surface of the door panel 11a is shorter than the gap W, the outer side surface 14b of the air conditioning member 14 is formed on the sill 13 of the car 3. It is sufficient to determine the thickness D of the air conditioning member 14 to such an extent that it does not protrude from the front edge.

かくして上述した如くドアパネル１１（１１ａ,１１ｂ）の前面に前記整風部材１４を取り付けたエレベータによれば、前記乗りかご３の上昇時に前記ドアパネル１１の前面に沿って流れる空気の多くは、前記整風部材１４の傾斜面１１ｃに導かれて該整風部材１４と前記ドアパネル１１（１１ａ,１１ｂ）の前面との間に形成された開口部を介して前記乗りかご３の側部に導かれる。従って前記乗りかご３の敷居（カーシル）１３の前縁部と、前記乗場側の敷居（ホールシル）２ａの前端部との隙間Ｗに流れ込む空気流の量が大幅に減少する。この結果、前記敷居１３,２ａの各前縁部間の隙間Ｗを通過する風（空気）の圧縮量が少なくなり、これに伴って騒音（バフ音）のレベルも低下する。従って乗りかご３内に伝播する騒音のレベルを大幅に低減することが可能となる。 Thus, according to the elevator in which the air conditioning member 14 is attached to the front surface of the door panel 11 (11a, 11b) as described above, most of the air flowing along the front surface of the door panel 11 when the car 3 is lifted is the air conditioning member. 14 is led to the side of the car 3 through an opening formed between the air conditioning member 14 and the front surface of the door panel 11 (11a, 11b). Accordingly, the amount of air flow flowing into the gap W between the front edge of the sill (carsill) 13 of the car 3 and the front end of the sill (hole sill) 2a on the landing side is greatly reduced. As a result, the amount of compression of the wind (air) that passes through the gaps W between the front edges of the sills 13 and 2a is reduced, and the level of noise (buffing) is also lowered accordingly. Therefore, the level of noise propagating in the car 3 can be greatly reduced.

図５は、前記整風部材１４を備えていない従来のエレベータ、および前記整風部材１４を備えた第１の実施形態に係るエレベータにおける前記敷居１３,２ａの各前縁部間の隙間Ｗを通過する風（空気）の圧縮圧力の変化を対比して示すシミュレーション（流体解析）結果である。この図５に示すシミュレーション結果からも明らかなように、前記整風部材１４を備えることで、前記敷居１３,２ａの各前縁部間の隙間Ｗを通過する風（空気）の圧力変化を緩やかにし、その変動量を抑えることができるので、その分、前記騒音（バフ音）の発生レベルを低減することができ（図の圧力Ｐ）、騒音レベルを低減する上での実用的利点が大である。 FIG. 5 shows a conventional elevator that does not include the air conditioning member 14 and a gap W between the front edge portions of the sills 13 and 2 a in the elevator according to the first embodiment that includes the air conditioning member 14. It is the simulation (fluid analysis) result which contrasts and shows the change of the compression pressure of a wind (air). As is clear from the simulation results shown in FIG. 5, the provision of the air conditioning member 14 moderates the pressure change of the wind (air) passing through the gap W between the front edge portions of the sills 13 and 2a. Since the fluctuation amount can be suppressed, the generation level of the noise (buff sound) can be reduced by that amount (pressure P in the figure), and the practical advantage in reducing the noise level is great. is there.

尚、前記整風部材１４については、例えば図６(ａ)に示すように、所定厚みの板材を折り曲げ加工して形成したものであっても良い。また或いは、例えば図６(ｂ)に示すように前記整風部材１４の傾斜面１４ｃを、前記ドアパネル１１の前面側から乗りかご敷居（カーシル）１３の前縁側に向けて低く形成しても良い。この図６(ｂ)に示すような傾斜面１４ｃの向きを逆にした場合、前記敷居１３,２ａの隙間Ｗに導かれる風（空気）の量自体を低減することはできない。しかし前記傾斜面１４ｃによって前記敷居１３,２ａの隙間Ｗに導かれる風（空気）の流れを円滑（スムーズ）にすることができ、風（空気）の急激な圧力変化を低減することができる。この結果、前記騒音（バフ音）の発生レベル（音圧）を低減して乗りかご３内に伝播する騒音のレベルを低減することが可能となる。 The air conditioning member 14 may be formed by bending a plate material having a predetermined thickness, for example, as shown in FIG. Alternatively, for example, as shown in FIG. 6B, the inclined surface 14 c of the air conditioning member 14 may be formed lower from the front surface side of the door panel 11 toward the front edge side of the car sill 13. When the direction of the inclined surface 14c as shown in FIG. 6B is reversed, the amount of wind (air) guided to the gap W between the sills 13 and 2a cannot be reduced. However, the flow of wind (air) guided to the gap W between the sills 13 and 2a by the inclined surface 14c can be made smooth, and a sudden pressure change of the wind (air) can be reduced. As a result, it is possible to reduce the level of noise (buff sound) generated (sound pressure) and reduce the level of noise propagating into the car 3.

図７は本発明の第２の実施形態を示している。この第２の実施形態は、前述した整風部材１４に代えて、前記敷居１３からの高さＨが前記ドアパネルの幅方向に変化する傾斜面１５ａを備えた整風部材１５を前記ドアパネル１１（１１ａ）の前面下部に取り付けたことを特徴としている。前記整風部材１５は、図７に示すように前記ドアパネル１１の幅方向の一端部から他端部に向けて、前記敷居１３からの高さＨを低く形成した傾斜面１５ａを備えた横長の略三角形状の平板体からなる。 FIG. 7 shows a second embodiment of the present invention. In the second embodiment, instead of the air conditioning member 14 described above, the air conditioning member 15 provided with an inclined surface 15a whose height H from the sill 13 changes in the width direction of the door panel is the door panel 11 (11a). It is attached to the front lower part of As shown in FIG. 7, the air conditioning member 15 has an inclined surface 15 a having an inclined surface 15 a formed with a low height H from the sill 13 from one end to the other end in the width direction of the door panel 11. It consists of a triangular plate.

この整風部材１５は、前述した実施形態と同様に前記ドアパネル１１ａの前面下部に、前記敷居１３の前端部に沿って取り付けられ、前記ドアパネル１１ａと一体に前記乗りかご３の幅方向にスライド自在に設けられる。そして前記整風部材１５は、前記乗りかご３の上昇時に前記ドアパネル１１ａ,１１ｂの前面に沿って流れる空気流を、平板体からなる前記整風部材１５の内側面と前記ドアパネル１１ａ,１１ｂとの間に形成された空間部に導き、前記乗りかご３の側部に逃がす役割を担う。従って前記空気流の多くは前記空間部を介して前記乗りかご３の側部に導かれ、これによって前記敷居１３,２ａの隙間Ｗに導かれる風（空気）の量が低減される。 The air conditioning member 15 is attached to the lower front portion of the door panel 11a along the front end of the sill 13 in the same manner as in the above-described embodiment, and is slidable in the width direction of the car 3 integrally with the door panel 11a. Provided. The air conditioning member 15 causes the air flow flowing along the front surfaces of the door panels 11a and 11b when the car 3 is lifted between the inner surface of the air conditioning member 15 formed of a flat plate and the door panels 11a and 11b. It leads to the formed space and plays a role of escaping to the side of the car 3. Therefore, most of the air flow is guided to the side portion of the car 3 through the space portion, thereby reducing the amount of wind (air) guided to the gap W between the sills 13 and 2a.

しかも前記乗りかご３の上昇時に前記ドアパネル１１の前面に沿って流れる空気流は、前記整風部材１５における傾斜面１５ａの高さＨの高い左端側において最も早く前記敷居１３,２ａの隙間Ｗに導かれて圧縮される。また前記空気流は前記整風部材１５の高さＨの低い右端側においては最も遅く前記隙間Ｗに導かれて圧縮される。換言すれば前記敷居１３,２ａの隙間Ｗに入り込む空気は、前記整風部材１５の左端側と右端側とにおいて、前記整風部材１５が乗場２の敷居２ａが通過する時間差を経て圧縮される。すると前記隙間Ｗに入り込んで圧縮された後、前記敷居２ａの通過に伴って昇降路内に解放される空気の圧力変動が緩やかになり、空気の圧力変動に伴うバフ音の発生レベル（音圧）が低くなる。 Moreover, the airflow that flows along the front surface of the door panel 11 when the car 3 is lifted is guided to the gap W between the sills 13 and 2a earliest on the left end side where the height H of the inclined surface 15a of the air conditioning member 15 is high. It is compressed. Further, the air flow is led to the gap W at the latest on the right end side where the height H of the air conditioning member 15 is low, and is compressed. In other words, the air entering the gap W between the sills 13, 2 a is compressed on the left end side and the right end side of the conditioned member 15 through a time difference that the conditioned member 15 passes through the sill 2 a of the landing 2. Then, after entering the gap W and being compressed, the pressure fluctuation of the air released into the hoistway with the passage of the sill 2a becomes moderate, and the generation level (sound pressure) of the buff sound accompanying the air pressure fluctuation is reduced. ) Becomes lower.

図８は、前記整風部材を備えていない従来のエレベータ、および幅方向に上端の高さが変化する傾斜面１５ａを有する前記整風部材（傾斜整風部材）１５を備えた第２の実施形態に係るエレベータにおける前記敷居１３,２ａの各前縁部間の隙間Ｗを通過する風（空気）の圧縮圧力の変化を対比して示すシミュレーション（流体解析）結果である。この図８に示すシミュレーション結果からも明らかなように、前記整風部材１５を備えることで、前記敷居１３,２ａの各前縁部間の隙間Ｗを通過する風（空気）の圧力変化を時間ｔ１から時間（ｔ１＋ｔ２）だけ緩やかにし、その変動量を抑えることができるので、その分、前記騒音（バフ音）の発生レベルを低減することができ、騒音レベルを低減する上での実用的利点が大である。 FIG. 8 relates to a second embodiment that includes a conventional elevator that does not include the air-conditioning member, and the air-conditioning member (inclined air-conditioning member) 15 that has an inclined surface 15a whose upper end height changes in the width direction. It is the simulation (fluid analysis) result which contrasts and shows the change of the compression pressure of the wind (air) which passes the clearance gap W between each front edge part of the said sills 13 and 2a in an elevator. As is clear from the simulation results shown in FIG. 8, by providing the air conditioning member 15, the pressure change of the wind (air) passing through the gap W between the front edge portions of the sills 13 and 2a is changed over time t1. From time to time (t1 + t2), and the amount of fluctuation can be suppressed. Therefore, the generation level of the noise (buff sound) can be reduced correspondingly, and there is a practical advantage in reducing the noise level. It ’s big.

例えば、乗りかご３の上昇速度が１２０ｍ／分であり、前記ドアパネル１１ａの前面に設けられる前記整風部材１５の傾斜面１５ａの左端側と右端側の高さに８０ｍｍの差があるとする。すると前記乗りかご３の上昇時に前記整風部材１５の左側上端が前記敷居２ａに到達した後、その右側上端が前記敷居２ａを通過するまでの時間（ｔ２）は、前記高さの差８０ｍｍ分が通過する時間で、０.０４秒となる。この時間分だけ、乗りかご３の上昇に起因する空気の圧力変動が緩やかになり、前記整風部材１５がない場合に比べて周波数が低いバフ音が発生することになる。すなわち、人間は、音圧変化量が同じでも、その周波数が低いほど音が小さいと感じる聴感を有していることが知られている。従って前記整風部材１５を設けることにより、上記バフ音は騒音レベル（聴感上聞こえる音の大きさ）が低減することになる。また、前記整風部材１５の傾斜面１５ａの左端側と右端側の高さをさらに大きくとることで、バフ音の周波数をより低下させ、バフ音の周波数を人間の可聴周波数（一般的には２０Ｈz〜２０ｋＨz）よりも低く抑えることができ、上記バフ音が騒音として伝播することがなくなる。即ち、上記実施形態によれば、バフ音の発生時間を長くすることによってその周波数を低下させ、これによって可聴周波数帯域の騒音の発生を抑えて静音効果を持たせることが可能となる。 For example, it is assumed that the ascending speed of the car 3 is 120 m / min, and there is a difference of 80 mm in the height between the left end side and the right end side of the inclined surface 15a of the air conditioning member 15 provided on the front surface of the door panel 11a. Then, after the upper left end of the air conditioning member 15 reaches the sill 2a when the car 3 is raised, the time (t2) until the upper right end passes through the sill 2a is equal to the height difference of 80 mm. Passing time is 0.04 seconds. For this time, the air pressure fluctuation caused by the rise of the car 3 becomes gentle, and a buffing sound having a lower frequency than the case where the air conditioning member 15 is not provided is generated. That is, it is known that human beings have a sense of hearing that the sound is smaller as the frequency is lower, even if the amount of change in sound pressure is the same. Therefore, by providing the air conditioning member 15, the buff sound has a reduced noise level (the volume of sound that can be heard for hearing). Further, by further increasing the height of the left end side and the right end side of the inclined surface 15a of the air conditioning member 15, the frequency of the buff sound is further reduced, and the frequency of the buff sound is reduced to a human audible frequency (generally 20 Hz). ˜20 kHz), and the buff sound does not propagate as noise. That is, according to the above-described embodiment, it is possible to reduce the frequency by increasing the generation time of the buff sound, thereby suppressing the generation of noise in the audible frequency band and providing a silent effect.

尚、前記整風部材１５の幅方向に上端の高さが変化する傾斜面１５ａについては、例えば図９(ａ)に示すように前記敷居１３からの高さが前記ドアパネルの幅方向の中央部からその両端部に向けて低く形成された、いわゆる山型（凸型）形状であっても良い。或いは逆に、図９(ｂ)に示すように前記敷居１３からの高さが前記ドアパネルの幅方向の中央部からその両端部に向けて高く形成された、いわゆる谷型（凹型）形状であっても良い。更には上記傾斜面１５ａを、その幅方向の傾きが緩やかに変化する湾曲面として形成することも可能である。 In addition, about the inclined surface 15a from which the height of the upper end changes in the width direction of the said air conditioning member 15, for example, as shown to Fig.9 (a), the height from the said sill 13 is from the center part of the width direction of the said door panel. A so-called mountain-shaped (convex) shape formed low toward both ends may be used. Or, conversely, as shown in FIG. 9 (b), the height from the sill 13 is a so-called valley-shaped (concave) shape in which the height from the center in the width direction of the door panel is increased toward both ends. May be. Furthermore, the inclined surface 15a can be formed as a curved surface whose inclination in the width direction changes gently.

ところで上述した前述した整風部材１５を、図１０(ａ)(ｂ)に示すように、前記２枚のドアパネル１１ａ,１１bのそれぞれに対応させて設けた２つの整風部材１６,１７として実現することも可能である。この第３の実施形態に係る前記２つの整風部材１６,１７は、前述した第２の実施形態における前記整風部材１５を、そのスライド方向に左右に分割し、１つの連続した傾斜面を形成するものからなる。特に前記出入口の左側に位置付けられて前記ドアパネル１１ａの前面に取り付ける前記整風部材１６については、前記出入口の右側に位置付けられて前記ドアパネル１１ｂの前面に取り付ける前記整風部材１７の高さの分だけ、その下側を切り取った大きさのものとして実現される。 By the way, the above-described air conditioning member 15 is realized as two air conditioning members 16 and 17 provided corresponding to the two door panels 11a and 11b, respectively, as shown in FIGS. 10 (a) and 10 (b). Is also possible. The two air conditioning members 16 and 17 according to the third embodiment divide the air conditioning member 15 in the above-described second embodiment into left and right in the sliding direction to form one continuous inclined surface. Consists of things. In particular, the air conditioning member 16 that is positioned on the left side of the doorway and attached to the front surface of the door panel 11a has the height of the air conditioning member 17 that is positioned on the right side of the doorway and attached to the front surface of the door panel 11b. It is realized as the size of the lower side.

また前記整風部材１７は、前記ドアパネル１１ｂの前面との間に前記ドアパネル１１ｂが進入可能な隙間を形成して該ドアパネル１１ｂに取り付けられる。そして前記各ドアパネル１１ａ,１１bをスライドさせて図１０(ｂ)に示すように前記出入口を開放したとき、前記各整風部材１６,１７が上下方向に互いに重なり合うように前記各ドアパネル１１ａ,１１bの前面に前記傾斜面の高さ位置を異ならせてそれぞれ設ける。 The air conditioning member 17 is attached to the door panel 11b by forming a gap through which the door panel 11b can enter between the front surface of the door panel 11b. When the door panels 11a and 11b are slid to open the doorway as shown in FIG. 10B, the front surfaces of the door panels 11a and 11b are arranged so that the air conditioning members 16 and 17 overlap each other in the vertical direction. Are provided with different height positions of the inclined surfaces.

このようにして前記２枚のドアパネル１１ａ,１１ｂの前面にそれぞれ設けられる前記整風部材１６,１７によれば、前記ドアパネル１１ａ,１１ｂを展開して前記乗りかご３の出入口を閉じたときには、前述したように前記整風部材１６,１７が前記敷居１３の前端部に沿って敷居１３の幅方向に傾斜する傾斜面を形成するので、前述した実施形態と同様に騒音（バフ音）の発生レベルを低減する作用を呈する。 Thus, according to the wind control members 16 and 17 provided on the front surfaces of the two door panels 11a and 11b, respectively, when the door panels 11a and 11b are expanded and the entrance / exit of the car 3 is closed, the above-described operation is performed. As described above, the air conditioning members 16 and 17 form an inclined surface that inclines in the width direction of the sill 13 along the front end portion of the sill 13, so that the generation level of noise (buff sound) is reduced as in the above-described embodiment. Exhibits the action of

そして前記ドアパネル１１ａ,１１ｂをスライドさせて前記出入口の側部に収納し、該出入口を開放した際には、前記整風部材１６,１７は図１０(ｂ)に示したように上下に重なり合う。そして図１１に概略的な平面図を示すように、前記整風部材１６,１７が前記乗りかご３の側部に大きく突出することがなくなる。従って前記整風部材１６,１７の設置に要する空間を狭くすることができ、限られた大きさの昇降路１の内部空間を有効に利用して前記前記ドアパネル１１ａ,１１ｂの前面に前記整風部材１６,１７を取り付けることが可能となる。 When the door panels 11a and 11b are slid and housed in the side portions of the doorway, and the doorway is opened, the air conditioning members 16 and 17 overlap each other as shown in FIG. 10 (b). Then, as shown in a schematic plan view in FIG. 11, the air conditioning members 16 and 17 do not protrude significantly from the side of the car 3. Therefore, the space required for the installation of the air conditioning members 16 and 17 can be narrowed, and the air conditioning member 16 can be provided in front of the door panels 11a and 11b by effectively using the internal space of the hoistway 1 having a limited size. , 17 can be attached.

ところで前記乗りかご３の前面部には、乗場側のドア装置との係合機構や挟み込み検知用のセンサ等が設置され、前記敷居１３の前端部に沿って十分な大きさ、具体的には大きな傾き角度の傾斜面を有する整風部材１５,１６,１７を設置することが困難な場合がある。このような場合、例えば図１２に示すように前記乗場敷居２ａの下部、具体的には乗場２側の出入口上部に設けられるドア開閉機構の前面に、前記整風部材１５と同様な補助整風部材１８を、その傾斜面を下側に向けて設けるようにすれば良い。この際、前記補助整風部材１８の傾斜面を、前記乗りかご３に設ける前記整風部材１５,１６,１７の傾斜面と逆向きにする。 By the way, an engagement mechanism with a landing-side door device, a pinch detection sensor, and the like are installed on the front surface portion of the car 3, and are sufficiently large along the front end portion of the sill 13, specifically, It may be difficult to install the air conditioning members 15, 16, and 17 having inclined surfaces with a large inclination angle. In such a case, for example, as shown in FIG. 12, an auxiliary air conditioning member 18 similar to the air conditioning member 15 is provided at the lower part of the landing sill 2a, specifically on the front surface of a door opening / closing mechanism provided at the upper part of the entrance / exit on the landing 2 side. May be provided with the inclined surface facing downward. At this time, the inclined surface of the auxiliary air-conditioning member 18 is set in the opposite direction to the inclined surfaces of the air-conditioning members 15, 16, and 17 provided on the car 3.

このような補助整風部材１８を設ければ、該補助整風部材１８の傾き角度の分だけ前記整風部材１５,１６,１７の傾斜面の傾き角度を等価的に大きくすることができる。従って前記補助整風部材１８の下端部に対する前記整風部材１５,１６,１７の傾斜面の傾き角度が大きくなる分、該整風部材１５,１６,１７による騒音（バフ音）の発生レベルおよび発生周波数の低減効果を期待することが可能となる。故に、傾斜面の傾き角度が小さい小型の整風部材１５,１６,１７しか前記ドアパネル１１の前面下部に取り付けることができない場合であっても、前記騒音（バフ音）を低減して前記乗りかご３に伝播する騒音を抑制することができる。 If such an auxiliary air conditioning member 18 is provided, the inclination angle of the inclined surfaces of the air conditioning members 15, 16, and 17 can be increased equivalently by the inclination angle of the auxiliary air conditioning member 18. Accordingly, since the inclination angle of the inclined surface of the air conditioning members 15, 16, 17 with respect to the lower end portion of the auxiliary air conditioning member 18 increases, the generation level and frequency of the noise (buff sound) generated by the air conditioning members 15, 16, 17 are increased. A reduction effect can be expected. Therefore, even when only the small air-conditioning members 15, 16, 17 having a small inclination angle of the inclined surface can be attached to the lower front portion of the door panel 11, the noise (buffing sound) is reduced and the car 3 is reduced. It is possible to suppress noise propagating to the surface.

尚、前記乗りかご３の下降時においても前記敷居１３,２ａの各前端部間の隙間Ｗを通過する風（空気）に起因する騒音（バフ音）が問題となるような場合には、例えば図１３に示すように前記乗りかご３の敷居１３の下面側に、前述した整風部材１５と同様な整風部材１９を該敷居１３の前端部に沿って設けるようにすれば良い。このような整風部材１９によれば、前記乗りかご３の下降時に前記敷居１３,２ａの各前端部間の隙間Ｗを通過する風（空気）の流れ和らげることができる。従って前述した実施形態と同様に、前記乗りかご３の下降時における騒音（バフ音）の発生を抑制することが可能となる。 In the case where noise (buffing) caused by wind (air) passing through the gaps W between the front ends of the sills 13 and 2a becomes a problem even when the car 3 is lowered, for example, As shown in FIG. 13, a wind control member 19 similar to the wind control member 15 described above may be provided along the front end of the threshold 13 on the lower surface side of the threshold 13 of the car 3. According to such a wind regulation member 19, the flow of air (air) passing through the gap W between the front end portions of the sills 13, 2 a can be moderated when the car 3 is lowered. Therefore, as in the above-described embodiment, it is possible to suppress the generation of noise (buffing sound) when the car 3 is lowered.

尚、本発明は上述した各実施形態に限定されるものではない。例えば前記整風部材１４,１５,１６,１７の大きさ・形状については前記乗りかご３の寸法的仕様、特に前記ドアパネル１１（１１ａ,１１ｂ）の大きさ（幅）、および前記乗りかご３の昇降速度に応じて定めれば良いものである。 In addition, this invention is not limited to each embodiment mentioned above. For example, the size and shape of the air conditioning members 14, 15, 16, 17 are dimensional specifications of the car 3, particularly the size (width) of the door panel 11 (11 a, 11 b), and the raising / lowering of the car 3. It may be determined according to the speed.

例えば、前記整風部材１４は、図１４（ａ）に示すように、前記ドアパネル１１の前面側に対向する面が凸状となる曲面を形成しても良い。すなわち、図１４（ａ）のＸ−Ｘ´に沿う断面は、図１４（ｂ）に示すように、その横断面における傾斜面１４ｃ´が直線ではなく曲線形状となっている。 For example, the air conditioning member 14 may form a curved surface having a convex surface facing the front side of the door panel 11 as shown in FIG. That is, as shown in FIG. 14B, the cross-section along the line XX ′ in FIG. 14A has an inclined surface 14c ′ in the cross section that is not a straight line but a curved shape.

また前記整風部材１４,１５,１６,１７の前記ドアパネル１１（１１ａ,１１ｂ）への取り付け構造についても、該ドアパネル１１（１１ａ,１１ｂ）のスライド移動を阻害しないようにすれば十分である。その他、本発明はその要旨を逸脱しない範囲で種々変形して実施することができる。 In addition, it is sufficient that the air conditioning members 14, 15, 16, 17 are attached to the door panel 11 (11a, 11b) so as not to inhibit the sliding movement of the door panel 11 (11a, 11b). In addition, the present invention can be variously modified and implemented without departing from the scope of the invention.
