　従来のエレベーター装置における乗りかごでは、換気隙間が形成されたままでも乗りかご内騒音に大きな影響はなかった。しかし、今後、乗りかご速度がさらに高速化されると、換気隙間から乗りかご内に伝達される騒音が大きな問題となり得る。 In the car in the conventional elevator apparatus, the noise in the car was not greatly affected even if the ventilation gap was formed. However, if the speed of the car is further increased in the future, noise transmitted from the ventilation gap into the car can be a big problem.

　以下、本発明の実施の形態を図面に基づいて説明する。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.
　図９を参照して、本発明に係るエレベーター装置の一実施例について説明する。図９は本発明の一実施例に係るトラクション式エレベーター装置を示す模式図である。 Referring to FIG. 9, an embodiment of the elevator apparatus according to the present invention will be described. FIG. 9 is a schematic view showing a traction type elevator apparatus according to an embodiment of the present invention.
　本実施例のトラクション式エレベーター装置は、開閉するかごドア１ａを有する乗りかご１、釣合おもり１０２、電動機１０３Ａと電動機１０３Ａに接続したシーブ１０３Ｂとを含む巻上機１０３、ロープ２、乗りかご１に設けられた滑車１０５ａ、釣合おもり１０２に設けられた滑車１０５ｂ、昇降路１０７の頂部に固定された滑車１０６、巻上機１０３やエレベーター装置に設けられた他の装置（機器）を制御する制御盤（制御装置）１０１を備えている。ロープ２の一端は昇降路１０７の頂部に固定され、乗りかご１の滑車１０５ａ、滑車１０６、シーブ１０３Ｂ、滑車１０６、釣合おもり１０２の滑車１０５ｂの順で掛け渡され、他端が昇降路１０７の頂部で固定されている。 The traction type elevator apparatus according to the present embodiment includes a car 1 having a car door 1a that opens and closes, a counterweight 102, a hoisting machine 103 including a motor 103A and a sheave 103B connected to the motor 103A, a rope 2, and a car 1 A pulley 105a provided on the counterweight, a pulley 105b provided on the counterweight 102, a pulley 106 fixed to the top of the hoistway 107, the hoisting machine 103 and other devices (equipment) provided on the elevator device. A control panel (control device) 101 is provided. One end of the rope 2 is fixed to the top of the hoistway 107, and the pulley 105 a of the car 1, the pulley 106, the sheave 103 </ b> B, the pulley 106, and the pulley 105 b of the counterweight 102 are spanned in this order, and the other end of the rope 2. It is fixed at the top.
　本実施例のエレベーター装置は、建屋に形成された昇降路１０７内に乗りかご１と釣合おもり１０２とを両者の重量がバランスするようにロープ２を介して吊り下げる。ロープ２が巻き掛けられた巻上機１０３を制御盤１０１で駆動制御することにより、ロープ２を介して乗りかご１と釣合おもり１０２とが互いに反対方向に昇降される。 The elevator apparatus according to the present embodiment suspends the car 1 and the counterweight 102 through the rope 2 so that the weights of the elevator car 1 and the counterweight 102 are balanced in a hoistway 107 formed in the building. By driving and controlling the hoisting machine 103 around which the rope 2 is wound by the control panel 101, the car 1 and the counterweight 102 are lifted and lowered in opposite directions via the rope 2.
　エレベーター装置には、上述した装置以外にも、ガイドレール、調速機、緩衝器などが設けられているが、図９では図示を省略している。 In addition to the above-described devices, the elevator device is provided with a guide rail, a speed governor, a shock absorber, etc., but is not shown in FIG.
　また、本発明は上述したトラクション式エレベーター装置に限定される訳ではなく、その他の方式のエレベーター装置に適用することができる。しかし、後述する換気隙間閉塞装置７は、乗りかご１の高速走行時における風圧を利用して閉塞動作を行うことから、乗りかご１を高速で昇降させることができるトラクション式エレベーター装置に用いられることにより、効果的に動作させることができる。また、各装置（機器）の配置は、上述した配置に限定される訳ではなく、その他の配置を採用することができる。 Further, the present invention is not limited to the traction type elevator device described above, and can be applied to other types of elevator devices. However, since the ventilation gap closing device 7 described later performs a closing operation using the wind pressure when the car 1 is traveling at a high speed, the ventilation gap closing device 7 is used for a traction type elevator device that can raise and lower the car 1 at a high speed. Thus, it can be effectively operated. Further, the arrangement of each device (device) is not limited to the arrangement described above, and other arrangements can be adopted.
　図１および図２を参照して、本発明の一実施例に係るエレベーター装置の乗りかご１について、説明する。図１は、本発明の一実施例に係るエレベーター装置の乗りかご１を示す正面図である。図２は、図１に示した乗りかご１の側面図（ただし、換気隙間閉塞装置の図示を省略）である。 With reference to FIG. 1 and FIG. 2, the elevator car 1 of an elevator apparatus according to an embodiment of the present invention will be described. FIG. 1 is a front view showing a car 1 of an elevator apparatus according to an embodiment of the present invention. FIG. 2 is a side view of the car 1 shown in FIG. 1 (however, the ventilation gap closing device is not shown).
　乗りかご１は、かご床３と、かご床３の縁（外周）に配置されると共にかご床３から上側に起立する部分（起立部）４ａを有した床フレーム４と、床フレーム４に下部が固定された側板５と、側板５に囲まれた空間の上部を覆う天井板６などを有して構成されている。側板５と床フレーム４との間には、詳細を後述する乗りかご１の内外を連通可能な換気隙間８と、この換気隙間８を所定の条件下で閉じ塞ぐ換気隙間閉塞装置７が構成されている。換気隙間８を形成するために、側板５と床フレーム４との間には、複数の隙間形成部材８ａが乗りかご１の周方向に間隔を空けて設けられている。 The car 1 includes a car floor 3, a floor frame 4 that is disposed on an edge (outer periphery) of the car floor 3 and has a portion (standing part) 4 a that stands upward from the car floor 3, and a lower part of the floor frame 4. Is fixed to the side plate 5 and the ceiling plate 6 covering the upper part of the space surrounded by the side plate 5. Between the side plate 5 and the floor frame 4, a ventilation gap 8 capable of communicating inside and outside of the car 1, which will be described in detail later, and a ventilation gap closing device 7 for closing and closing the ventilation gap 8 under a predetermined condition are configured. ing. In order to form the ventilation gap 8, a plurality of gap forming members 8 a are provided between the side plate 5 and the floor frame 4 at intervals in the circumferential direction of the car 1.
　なお、換気隙間閉塞装置７における「閉塞」は、密閉を意味するものではなく、閉塞前の状態に対して隙間を減少させ、隙間がほぼ閉じられた状態になることを意味する。 It should be noted that “occlusion” in the ventilation gap closing device 7 does not mean sealing, but means that the gap is reduced with respect to the state before closing and the gap is almost closed.
　図３～図７を参照して、換気隙間閉塞装置７について説明する
　図３は、図１に示した乗りかごの停止状態における換気隙間閉塞装置７を示す拡大断面図である。図４は、換気隙間閉塞装置の外観を示す斜視図である。 The ventilation gap closing device 7 will be described with reference to FIGS. 3 to 7. FIG. 3 is an enlarged sectional view showing the ventilation gap closing device 7 when the car shown in FIG. 1 is stopped. FIG. 4 is a perspective view showing the appearance of the ventilation gap closing device.
　側板５の下端と床フレーム４の起立部４ａの上端との間には、乗りかご１の内外を連通する換気隙間８が形成されている。換気隙間８を開放または閉塞可能な換気隙間閉塞装置７は、乗りかご１の停止状態で換気隙間８を開放状態にし、一方、乗りかご１の高速走行時には風圧を利用してほぼ閉塞状態とするように構成されている。 Between the lower end of the side plate 5 and the upper end of the upright portion 4a of the floor frame 4, a ventilation gap 8 that communicates the inside and outside of the car 1 is formed. The ventilation gap closing device 7 that can open or close the ventilation gap 8 opens the ventilation gap 8 when the car 1 is stopped, while making the car 1 almost closed using wind pressure when the car 1 is traveling at high speed. It is configured as follows.
　具体的は、換気隙間閉塞装置７は隙間閉塞部９と弾性変形部１１とを備えて構成されている。隙間閉塞部９は、換気隙間８を開く状態（換気隙間８を介して乗りかご１の内外が連通した状態）と換気隙間８を閉塞する状態とに変位可能な位置に配置されている。弾性変形部１１は、乗りかご１の高速走行時の風圧を利用して弾性変形し、換気隙間８が開いた状態から閉塞される状態に隙間閉塞部９を変位させる。 Specifically, the ventilation gap closing device 7 includes a gap closing portion 9 and an elastic deformation portion 11. The gap closing portion 9 is disposed at a position displaceable between a state in which the ventilation gap 8 is opened (a state in which the inside and outside of the car 1 communicate with each other via the ventilation gap 8) and a state in which the ventilation gap 8 is closed. The elastic deformation portion 11 is elastically deformed by using the wind pressure when the car 1 is traveling at high speed, and displaces the gap closing portion 9 from a state where the ventilation gap 8 is opened to a state where it is closed.
　換気隙間閉塞装置７の弾性変形部１１は、換気隙間閉塞装置７を乗りかご１側に取り付けるためのボルト１０を挿通する貫通孔（ボルト挿通孔）１１ａを有する。すなわち、弾性変形部（取り付け変形部）１１は、換気隙間閉塞装置７を乗りかご１側に取り付けるための取付部を構成している。弾性変形部１１は、ボルト１０によって上下方向（昇降方向）における一端部側が固定されており、他端部側が側板５に対して接離する方向に変形可能な状態で、側板５に保持されている。 The elastically deforming portion 11 of the ventilation gap closing device 7 has a through hole (bolt insertion hole) 11a through which a bolt 10 for attaching the ventilation gap closing device 7 to the car 1 side is inserted. That is, the elastic deformation portion (attachment deformation portion) 11 constitutes an attachment portion for attaching the ventilation gap closing device 7 to the car 1 side. The elastic deformation portion 11 is held by the side plate 5 in a state in which one end portion in the vertical direction (lifting direction) is fixed by the bolt 10 and the other end portion can be deformed in a direction in which the other end side is in contact with or separated from the side plate 5. Yes.
　隙間閉塞部９は、弾性変形部１１と一体的に構成されており、第１の隙間閉塞部９ａと第２の隙間閉塞部９ｂとを有する。第１の隙間閉塞部９ａは、換気隙間８の中に挿入されている。第２の隙間閉塞部９ｂは乗りかご１の外側に突出し、乗りかご１の外側に位置することで、乗りかご１の上昇時（上方向への走行時）および下降時（下方向への走行時）に相反する側に風圧を受ける。このために第２の隙間閉塞部９ｂは、昇降時風受け部（第１の風受け部）１２と下降時風受け部（第２の風受け部）１３とを備える。 The gap closing part 9 is configured integrally with the elastic deformation part 11 and has a first gap closing part 9a and a second gap closing part 9b. The first gap closing portion 9 a is inserted into the ventilation gap 8. The second gap closing portion 9b projects to the outside of the car 1 and is located outside the car 1, so that the car 1 is lifted (running upward) and lowered (running downward). Wind pressure on the opposite side. For this purpose, the second gap closing portion 9 b includes an up / down wind receiving portion (first wind receiving portion) 12 and a descending wind receiving portion (second wind receiving portion) 13.
　昇降時風受け部（第１の風受け部）１２は、乗りかご１の上昇時および下降時に相反する側に風圧を受けて弾性変形する。下降時風受け部（第２の風受け部）１３は、昇降時風受け部１２と一体的に形成されて乗りかご１の外側に位置し、特に乗りかご１の下降時に効果的に風圧を受けて弾性変形部１１の弾性変形を促す。 Ascending / descending wind receiving portion (first wind receiving portion) 12 is elastically deformed by receiving wind pressure on opposite sides when the car 1 is raised and lowered. The descending wind receiving portion (second wind receiving portion) 13 is formed integrally with the ascending / descending wind receiving portion 12 and is located outside the car 1, and effectively reduces the wind pressure when the car 1 is lowered. In response, the elastic deformation portion 11 is urged to elastically deform.
　上述した弾性変形部１１は、側板５の板面に垂直な方向に沿う断面において、側板５の外周面側に上下方向（乗りかご１の昇降方向）に沿うように配置され、上下方向に延設される上下方向延設部（第１の上下方向延設部）を構成する。 The elastic deformation portion 11 described above is arranged along the vertical direction (the up-and-down direction of the car 1) on the outer peripheral surface side of the side plate 5 in the cross section along the direction perpendicular to the plate surface of the side plate 5, and extends in the vertical direction. A vertically extending portion (a first vertically extending portion) is provided.
　上述した隙間閉塞部９は、弾性変形部１１の下端部に結合されている。第１の隙間閉塞部９ａは、乗りかご１内に向かって延びて水平に配置されている。すなわち第１の隙間閉塞部９ａは、側板５の板面に垂直な方向に沿う断面において、水平方向に延設される水平方向延設部を構成する。すなわち第１の隙間閉塞部９ａは、弾性変形部（取付部）１１の上下方向の一端部（下端部）に設けられて、換気隙間８の内側に向かって水平方向に延設される第１の水平方向延設部を構成する。 The gap closing portion 9 described above is coupled to the lower end portion of the elastic deformation portion 11. The first gap closing portion 9a extends horizontally into the car 1 and is disposed horizontally. That is, the first gap closing portion 9 a constitutes a horizontal extending portion that extends in the horizontal direction in a cross section along the direction perpendicular to the plate surface of the side plate 5. That is, the first gap closing portion 9 a is provided at one end (lower end) in the vertical direction of the elastic deformation portion (attachment portion) 11 and extends in the horizontal direction toward the inside of the ventilation gap 8. The horizontally extending portion is configured.
　昇降時風受け部１２は、上下方向に対してほぼ直交するようにほぼ水平に配置されている。少なくとも弾性変形部１１および昇降時風受け部１２は、弾性材によって製作されて一体的なＬ字状（クランク状）に形成されている。下降時風受け部１３は、昇降時風受け部１２における乗りかご１の外側に突出した端部側に接続されており、下方の床フレーム４側に延びている。 The wind-receiving part 12 at the time of raising / lowering is arranged substantially horizontally so as to be substantially orthogonal to the vertical direction. At least the elastic deformation part 11 and the wind receiving part 12 during lifting are made of an elastic material and formed in an integral L shape (crank shape). The descending wind receiving portion 13 is connected to the end portion of the raising / lowering wind receiving portion 12 that protrudes to the outside of the car 1, and extends to the lower floor frame 4 side.
　すなわち第２の隙間閉塞部９ｂは、昇降時風受け部１２と下降時風受け部１３とにより、側板５の板面に垂直な方向に沿う断面がクランク状に折れ曲がった形状をしている。すなわち第２の隙間閉塞部９ｂは、側板５の板面に垂直な方向に沿う断面において、水平方向に延設される水平方向延設部（第２の水平方向延設部）９ｂ１と、上下方向に延設される上下方向延設部（第２の上下方向延設部）９ｂ２と、を備える。 That is, the second gap closing portion 9b has a shape in which a cross section along a direction perpendicular to the plate surface of the side plate 5 is bent into a crank shape by the wind receiving portion 12 during elevation and the wind receiving portion 13 during descending. That is, the second gap closing portion 9b includes a horizontal extending portion (second horizontal extending portion) 9b1 extending in the horizontal direction in the cross section along the direction perpendicular to the plate surface of the side plate 5, and And a vertically extending portion (second vertically extending portion) 9b2 extending in the direction.
　第２の水平方向延設部９ｂ１は、弾性変形部（取付部）１１の一端部（下端部）に設けられて、第１の隙間閉塞部９ａの延設方向とは反対側に向かって水平方向に延設される。第２の上下方向延設部９ｂ２は、第２の水平方向延設部９ｂ１における取付部１１との接続側とは反対側の先端部に、上下方向に沿って、取付部１１が設けられている側とは反対側に向かって延設される。第２の上下方向延設部９ｂ２（下降時風受け部１３）は、取付部１１が乗りかご１の外周面から離れるように弾性変形する場合に、この弾性変形を助長するように風圧を受ける。 The second horizontal extending portion 9b1 is provided at one end portion (lower end portion) of the elastically deformable portion (attachment portion) 11 and is horizontal toward the opposite side of the extending direction of the first gap closing portion 9a. It extends in the direction. The second vertically extending portion 9b2 is provided with a mounting portion 11 along the vertical direction at the tip of the second horizontal extending portion 9b1 opposite to the connection side with the mounting portion 11. It extends toward the opposite side of the side. The second vertically extending portion 9b2 (the descending wind receiving portion 13) receives wind pressure so as to promote the elastic deformation when the mounting portion 11 is elastically deformed so as to be separated from the outer peripheral surface of the car 1. .
　第２の水平方向延設部９ｂ１は昇降時風受け部１２により構成される。上下方向延設部９ｂ２は下降時風受け部１３により構成される。また昇降時風受け部１２は、後述するように、風圧を受けて弾性変形する弾性変形部を構成する。このため、弾性変形部１１を第１の弾性変形部と呼び、昇降時風受け部１２を第２の弾性変形部と呼んで区別する場合がある。 The second horizontal extending portion 9b1 is composed of a wind receiving portion 12 when moving up and down. The vertically extending portion 9b2 is configured by the descending wind receiving portion 13. Moreover, the wind receiving part 12 at the time of raising / lowering constitutes an elastic deformation part that elastically deforms by receiving wind pressure, as will be described later. For this reason, the elastically deformable portion 11 is sometimes referred to as a first elastically deformable portion, and the ascending / descending wind receiving portion 12 is sometimes referred to as a second elastically deformable portion.
　水平方向延設部９ｂ１は、第１の隙間閉塞部９ａと一つの水平面を構成する。すなわち、水平方向延設部９ｂ１と第１の隙間閉塞部９ａとが一つの平板状の部材で形成されている。 The horizontal extending portion 9b1 forms one horizontal plane with the first gap closing portion 9a. That is, the horizontal extending portion 9b1 and the first gap closing portion 9a are formed of a single flat plate member.
　特に本実施例では、水平方向延設部９ｂ１と上下方向延設部９ｂ２とは９０°の角度を成すように、上下方向延設部９ｂ２が水平方向延設部９ｂ１の一端部（第１の隙間閉塞部９ａとは反対側の端部）から下方に向かって延設されている。しかし、水平方向延設部９ｂ１と上下方向延設部９ｂ２とが成す角度は９０°である必要はなく、概ね９０°であればよい。要するに、第１の隙間閉塞部９ａおよび第２の隙間閉塞部９ｂにおいて、水平方向延設部９ａ，９ｂ１は概ね水平方向に延設されていればよく、上下方向延設部９ｂ２は概ね上下方向に延設されていればよい。 In particular, in this embodiment, the vertically extending portion 9b2 is connected to one end of the horizontally extending portion 9b1 (the first portion) so that the horizontally extending portion 9b1 and the vertically extending portion 9b2 form an angle of 90 °. It extends downward from the opposite end of the gap closing portion 9a. However, the angle formed by the horizontally extending portion 9b1 and the vertically extending portion 9b2 is not necessarily 90 °, and may be approximately 90 °. In short, in the first gap closing portion 9a and the second gap closing portion 9b, the horizontal extension portions 9a and 9b1 only need to extend in a substantially horizontal direction, and the vertical extension portion 9b2 has a substantially vertical direction. It should just be extended to.
　図３に示した乗りかご１の停止状態では、弾性変形部（第１の弾性変形部）１１および昇降時風受け部（第２の弾性変形部）１２で代表される弾性変形部は、弾性変形されることになる風圧を受けていないため、図示の状態に保持されている。すなわち、第１の隙間閉塞部９ａおよび昇降時風受け部（水平方向延設部９ｂ１）１２が、それぞれ弾性変形していない平板の状態を維持している。また床フレーム４よりも外側で床フレーム４との間に所定距離隔てて配置された下降時風受け部１３は、床フレーム４との間に隙間Ｓ１，Ｓ２を有し、乗りかご１の内側と外側とが換気隙間８を介して連通した状態に保持されている。この乗りかご１の停止状態では、昇降時風受け部１２は水平であり、第１の隙間閉塞部９ａも水平である。このとき、換気隙間８の断面積は最大となっている。 In the stop state of the car 1 shown in FIG. 3, the elastic deformation part represented by the elastic deformation part (first elastic deformation part) 11 and the wind receiving part during lift (second elastic deformation part) 12 is elastic. Since it is not subjected to the wind pressure to be deformed, it is kept in the state shown in the figure. That is, the first gap closing part 9a and the wind receiving part during lifting (horizontal extending part 9b1) 12 maintain a flat plate state that is not elastically deformed. The descending wind receiving portion 13 disposed outside the floor frame 4 and spaced apart from the floor frame 4 has gaps S1 and S2 between the floor frame 4 and the inside of the car 1. And the outside communicate with each other through the ventilation gap 8. When the car 1 is in a stopped state, the up-and-down wind receiving portion 12 is horizontal, and the first gap closing portion 9a is also horizontal. At this time, the cross-sectional area of the ventilation gap 8 is maximum.
　従って、乗りかご１の停止状態では、換気隙間閉塞装置７によって換気隙間８が塞がれることはなく、換気隙間８は開放状態であり、乗りかご１の内外は換気隙間８によって連通状態となっている。 Therefore, when the car 1 is stopped, the ventilation gap 8 is not closed by the ventilation gap closing device 7, the ventilation gap 8 is open, and the inside and outside of the car 1 are in communication with each other by the ventilation gap 8. ing.
　図５は、図１に示した乗りかごの下降時における換気隙間閉塞装置７の状態を示す拡大断面図である。 FIG. 5 is an enlarged sectional view showing a state of the ventilation gap closing device 7 when the car shown in FIG. 1 is lowered.
　乗りかご１の下降時に換気隙間閉塞装置７の昇降時風受け部１２および下降時風受け部１３は矢印で示すような方向の風力を受け、弾性変形部１１は図４に示すように弾性変形する。特に、昇降時風受け部１２および下降時風受け部１３が風圧を受けることにより、弾性変形部１１は全体としてボルト１０を中心にして反時計方向の回転力を受けたように弾性変形する。このため、弾性変形部１１の下方側（隙間閉塞部９との接続側）は、図示のように側板５から離れるように移動する。この移動に伴って隙間閉塞部９は、乗りかご１の内側に向かって延びた第１の隙間閉塞部９ａの内側端部を換気隙間８の内面（床フレーム４の上部、すなわち起立部４ａの上端）に接触させて位置規制される。このとき、第１の隙間閉塞部９ａは換気隙間８を閉じる。なお、第１の隙間閉塞部９ａと側板５との間にできる隙間８ａは弾性変形部１１により閉塞されており、換気隙間８は第１の隙間閉塞部９ａと弾性変形部１１とにより閉塞状態となる。 When the car 1 is lowered, the wind-in-winding portion 12 and the wind-in-winding portion 13 in the ventilation gap closing device 7 receive wind force in the direction indicated by the arrows, and the elastic deformation portion 11 is elastically deformed as shown in FIG. To do. In particular, when the wind receiving portion 12 at the time of lifting and the wind receiving portion 13 at the time of falling receive the wind pressure, the elastic deformation portion 11 as a whole is elastically deformed so as to receive a counterclockwise rotational force around the bolt 10. For this reason, the lower side of the elastic deformation part 11 (the connection side with the gap closing part 9) moves away from the side plate 5 as shown. Along with this movement, the gap closing portion 9 moves the inner end of the first gap closing portion 9a extending toward the inside of the car 1 to the inner surface of the ventilation gap 8 (the upper portion of the floor frame 4, that is, the standing portion 4a. The position is regulated by contacting the top edge. At this time, the first gap closing portion 9 a closes the ventilation gap 8. The gap 8a formed between the first gap closing portion 9a and the side plate 5 is closed by the elastic deformation portion 11, and the ventilation gap 8 is closed by the first gap closing portion 9a and the elastic deformation portion 11. It becomes.
　従って、図５のように乗りかご１が高速で下降している場合、換気隙間８を通して乗りかご１内に大きな騒音が入ることはなくなる。 Therefore, when the car 1 is descending at a high speed as shown in FIG. 5, no large noise enters the car 1 through the ventilation gap 8.
　その後、乗りかご１の下降速度が大きく低下したり、乗りかご１が停止したりすると、矢印の風圧は殆どなくなり、弾性変形部１１の風圧による弾性変形もなくなる。これにより、隙間閉塞部９の第１の隙間閉塞部９ａおよび昇降時風受け部（水平方向延設部９ｂ１）１２が水平に復帰し、換気隙間８は図３に示すような開放状態となる。 After that, when the descending speed of the car 1 is greatly reduced or the car 1 is stopped, the wind pressure indicated by the arrow almost disappears, and the elastic deformation due to the wind pressure of the elastic deformation portion 11 also disappears. As a result, the first gap closing part 9a of the gap closing part 9 and the wind receiving part during lifting (horizontal extending part 9b1) 12 return to the horizontal, and the ventilation gap 8 is in an open state as shown in FIG. .
　乗りかご１の下降時に、図５に示した状態からさらに、昇降時風受け部（水平方向延設部９ｂ１）１２が強い風圧を受けた場合に弾性変形するように構成してもよい。さらに、この変形を受けて第１の隙間閉塞部９ａの内側端部が床フレーム４に強く押し付けられることにより、第１の隙間閉塞部９ａが弾性変形するように構成してもよい。その場合も、昇降時風受け部１２および第１の隙間閉塞部９ａの変形よりも弾性変形部１１の弾性変形が先行して生じるようにするとよい。このために、隙間閉塞部９の剛性を弾性変形部１１の剛性よりも高くするとよい。 When the car 1 is lowered, it may be configured so as to be elastically deformed when the wind receiving portion (horizontal extending portion 9b1) 12 during lifting is subjected to strong wind pressure from the state shown in FIG. Further, the first gap closing portion 9a may be configured to be elastically deformed by receiving the deformation and pressing the inner end of the first gap closing portion 9a strongly against the floor frame 4. Also in that case, it is preferable that the elastic deformation of the elastic deformation portion 11 occurs prior to the deformation of the wind receiving portion 12 during lifting and the first gap closing portion 9a. For this reason, the rigidity of the gap closing part 9 is preferably higher than the rigidity of the elastic deformation part 11.
　なお本実施例では、隙間閉塞部９および弾性変形部１１を金属板で構成することを想定しているが、強度および信頼性を確保できれば樹脂材を用いてもよく、金属材と樹脂材と併用したハイブリッド構造など、金属以外の材料を用いてもよい。 In this embodiment, it is assumed that the gap closing portion 9 and the elastic deformation portion 11 are made of a metal plate, but a resin material may be used as long as strength and reliability can be ensured. You may use materials other than metal, such as a hybrid structure used together.
　図６は、図１に示した乗りかごの上昇時における換気隙間閉塞装置７の状態を示す拡大断面図である。図７は、図１に示した乗りかごの上昇時における換気隙間閉塞装置の変形過程を示す図である。 FIG. 6 is an enlarged sectional view showing a state of the ventilation gap closing device 7 when the car shown in FIG. 1 is raised. FIG. 7 is a diagram showing a deformation process of the ventilation gap closing device when the car shown in FIG. 1 is raised.
　図７において、（ａ）は乗りかご１の停止した状態（図３の状態）を示している。 7A shows a state where the car 1 is stopped (the state shown in FIG. 3).
　乗りかご１が高速で上昇する場合、換気隙間閉塞装置７は図６に矢印で示すような方向の風力を受ける。特に、昇降時風受け部１２は風圧を受け、隙間閉塞部９が弾性変形部１１との結合部を中心にして時計方向の回転力を受ける（図７（ｂ））。弾性変形部１１の下端部は、図６に示すように側板５に接触して変形が規制される。 When the car 1 rises at high speed, the ventilation gap closing device 7 receives wind force in the direction shown by the arrow in FIG. In particular, the wind receiving portion 12 during ascending / descending receives wind pressure, and the gap closing portion 9 receives a clockwise rotational force around the coupling portion with the elastic deformation portion 11 (FIG. 7B). As shown in FIG. 6, the lower end portion of the elastic deformation portion 11 comes into contact with the side plate 5 and deformation is restricted.
　昇降時風受け部１２はさらに強い風圧を受けると大きく弾性変形し、下降時風受け部１３の先端部（下端部）が乗りかご１の外周面（本実施例では、床フレーム４の外周面）に接触する（図７（ｃ））。下降時風受け部１３の先端部が床フレーム４の外周面に接触すると昇降時風受け部１２の変形が規制されるとともに、換気隙間８が下降時風受け部１３により閉じられる。このとき、換気隙間８の開口面の一部（上側部分）は弾性変形部１１により塞がれており、換気隙間８は下降時風受け部１３（第２の上下方向延設部９ｂ２）と弾性変形部１１とにより閉塞される。 The wind receiving portion 12 during lifting is greatly elastically deformed when receiving a stronger wind pressure, and the tip (lower end) of the wind receiving portion 13 during descending is the outer peripheral surface of the car 1 (in this embodiment, the outer peripheral surface of the floor frame 4). ) (FIG. 7 (c)). When the tip of the descending wind receiving portion 13 comes into contact with the outer peripheral surface of the floor frame 4, the deformation of the raising / lowering wind receiving portion 12 is restricted, and the ventilation gap 8 is closed by the descending wind receiving portion 13. At this time, a part (upper part) of the opening surface of the ventilation gap 8 is closed by the elastic deformation part 11, and the ventilation gap 8 is connected to the wind receiving part 13 (second vertically extending part 9b2) when descending. It is closed by the elastic deformation part 11.
　また昇降時風受け部１２が風圧を受けて変形する場合、第１の隙間閉塞部９ａが弾性変形部１１との結合部を中心にして時計方向に回動する。この第１の隙間閉塞部９ａの回動は、第１の隙間閉塞部９ａにおける乗りかご１の内側の端部が側板５の下端面に接触した状態で規制される。このとき弾性変形部１１の下端部は、図７（ｂ）にＡで示すように僅かに変形しているものの、上述したように弾性変形部１１の下端部が側板５に接触しているため変形が規制されている。 Further, when the wind receiving portion 12 is lifted and deformed due to the wind pressure, the first gap closing portion 9a rotates clockwise around the coupling portion with the elastic deformation portion 11. The rotation of the first gap closing portion 9 a is restricted in a state where the inner end portion of the car 1 in the first gap closing portion 9 a is in contact with the lower end surface of the side plate 5. At this time, the lower end portion of the elastic deformation portion 11 is slightly deformed as indicated by A in FIG. 7B, but the lower end portion of the elastic deformation portion 11 is in contact with the side plate 5 as described above. Deformation is regulated.
　従って、図示のように傾いた状態となった第１の隙間閉塞部９ａ、昇降時風受け部１２および下降時風受け部１３は、換気隙間８を塞ぐことになり、乗りかご１が高速で上昇するとき、乗りかご１内に大きな騒音が入ることはなくなる。 Accordingly, the first gap closing portion 9a, the up-and-down wind receiving portion 12 and the down-winding wind receiving portion 13 that are inclined as shown in the figure block the ventilation gap 8, and the car 1 can be moved at high speed. When climbing up, there will be no loud noise in the car 1.
　その後、乗りかご１の上昇速度が大きく低下したり、乗りかご１が停止したりすると、矢印の風圧は殆どなくなり、昇降時風受け部１２などの弾性変形もなくなって、換気隙間閉塞装置７は図３に示した元の状態に復帰する。この復帰によって第１の隙間閉塞部９ａおよび昇降時風受け部１２は水平となる状態に復帰し、換気隙間８は開放状態となり、乗りかご１の内外が連通した開放状態となる。 Thereafter, when the ascending speed of the car 1 is greatly reduced or the car 1 is stopped, the wind pressure indicated by the arrow is almost lost, and the wind receiving portion 12 during lifting is not elastically deformed. The original state shown in FIG. 3 is restored. As a result of this return, the first gap closing portion 9a and the wind receiving portion 12 during lifting are returned to a horizontal state, the ventilation gap 8 is opened, and the inside and outside of the car 1 are in an open state.
　乗りかご１の上昇時と下降時の説明から分かるように、特に乗りかご１の昇降方向に対して直交するように昇降時風受け部１２を設けているため、乗りかご１の上昇時にも下降時にも昇降時風受け部１２は効果的に風圧を受ける。このため、確実に隙間閉塞部９によって換気隙間８を閉塞することができる。しかも、風圧を利用しているため、特別の駆動装置を付加することなく簡単な構成で、隙間閉塞部９によって換気隙間８を閉塞または開放するように、換気隙間閉塞装置７を動作させることができる。 As can be seen from the explanation when the car 1 is raised and lowered, the wind-in-winding portion 12 is provided so as to be perpendicular to the raising and lowering direction of the car 1, so that the car 1 is lowered even when the car 1 is raised. At times, the wind receiving portion 12 at the time of raising and lowering effectively receives wind pressure. For this reason, the ventilation gap 8 can be reliably closed by the gap closing portion 9. Moreover, since the wind pressure is used, the ventilation gap closing device 7 can be operated so as to close or open the ventilation gap 8 by the gap closing portion 9 with a simple configuration without adding a special driving device. it can.
　次に、図８を参照して、換気隙間閉塞装置７の変更例を説明する。図８は、換気隙間閉塞装置の変更例を示す図であり、図１に示した乗りかごの停止状態における換気隙間閉塞装置の拡大断面図である。 Next, a modified example of the ventilation gap closing device 7 will be described with reference to FIG. FIG. 8 is a view showing a modified example of the ventilation gap closing device, and is an enlarged cross-sectional view of the ventilation gap closing device when the car shown in FIG. 1 is stopped.
　本変更例では、昇降時風受け部１２の下降時風受け部１３が設けられた端部に、上方に向かって延設した上昇時風受け部１４を設けている。すなわち上昇時風受け部１４は、上昇時昇降時風受け部１２における乗りかご１の外側に突出した端部側に接続されており、上方に向かって延びている。 In this modified example, an ascending wind receiving portion 14 extending upward is provided at an end of the ascending / descending wind receiving portion 12 where the descending wind receiving portion 13 is provided. That is, the rising wind receiving portion 14 is connected to the end portion of the rising rising / lowering wind receiving portion 12 that protrudes to the outside of the car 1 and extends upward.
　本変更例では、第２の隙間閉塞部９ｂは、昇降時風受け部１２と下降時風受け部１３と上昇時風受け部１４とより、側板５の板面に垂直な方向に沿う断面がＴ字状を成すような形状をしている。すなわち第２の隙間閉塞部９ｂは、側板５の板面に垂直な方向に沿う断面において、水平方向に延設される水平方向延設部（第２の水平方向延設部）９ｂ１と、上下方向において下方に延設される第２の上下方向延設部９ｂ２と、上下方向において上方に延設される第３の上下方向延設部９ｂ３とを備える。 In the present modified example, the second gap closing portion 9b has a cross section along the direction perpendicular to the plate surface of the side plate 5 by the up-and-down wind receiving portion 12, the down-winding wind receiving portion 13 and the up-winding wind receiving portion 14. It has a shape that forms a T-shape. That is, the second gap closing portion 9b includes a horizontal extending portion (second horizontal extending portion) 9b1 extending in the horizontal direction in the cross section along the direction perpendicular to the plate surface of the side plate 5, and A second vertical extending portion 9b2 extending downward in the direction and a third vertical extending portion 9b3 extending upward in the vertical direction.
　なお上下方向延設部９ｂ３は、上下方向延設部９ｂ２と同様に、概ね上下方向に延設されていればよい。 In addition, the up-down direction extension part 9b3 should just be extended in the up-down direction substantially similarly to the up-down direction extension part 9b2.
　本変更例では、上下方向延設部９ｂ３により、上昇時に受ける風圧を大きくすることができ、昇降時風受け部１２の変形を促進することができる。 In this modified example, the up-and-down direction extending portion 9b3 can increase the wind pressure received when ascending, and the deformation of the up-and-down wind receiving portion 12 can be promoted.
　上記実施例で換気隙間閉塞装置７は、乗りかご１の昇降移動時に風圧を受けて弾性変形する弾性変形部１１と、第１の隙間閉塞部９ａ、昇降時風受け部１２および下降時風受け部１３を含む隙間閉塞部９とを図４のように組み合わせたが、具体的な形状や構成はこれに限定しない。また上記実施例で換気隙間閉塞装置７は、側板５側にボルト１０で取り付けたが、この構成に限らず、他の部分に取り付けたり他の支持構成を用いたりすることもできる。また、換気隙間閉塞装置７を上下逆にして、床フレーム４に弾性変形部１１を固定するようにしてもよい。また、換気隙間８を側板５と天井板６との間に構成し、換気隙間閉塞装置７を側板５と天井板６との間に配置してもよい。この場合、換気隙間閉塞装置７は側板５と天井板６とのうちいずれか一方に固定するようにするとよい。 In the above embodiment, the ventilation gap closing device 7 includes an elastically deforming portion 11 that is elastically deformed by receiving wind pressure when the car 1 is moved up and down, a first gap closing portion 9a, a wind receiving portion 12 during lifting, and a wind receiving during descending. Although the gap closing portion 9 including the portion 13 is combined as shown in FIG. 4, the specific shape and configuration are not limited to this. Moreover, although the ventilation gap obstruction | occlusion apparatus 7 was attached to the side plate 5 side with the volt | bolt 10 in the said Example, it can attach not only to this structure but to another part, or can use another support structure. Further, the elastic gap 11 may be fixed to the floor frame 4 by turning the ventilation gap closing device 7 upside down. Further, the ventilation gap 8 may be configured between the side plate 5 and the ceiling plate 6, and the ventilation gap closing device 7 may be disposed between the side plate 5 and the ceiling plate 6. In this case, the ventilation gap closing device 7 may be fixed to either the side plate 5 or the ceiling plate 6.
　換気隙間閉塞装置７は、上述した実施例に対して、上下逆に取り付けられた場合、弾性変形部１１、第１の隙間閉塞部９ａおよび第２の隙間閉塞部９ｂの変形および動作が下降時と上昇時とで逆になる。すなわち取付部１１は、乗りかご１の上昇時に、乗りかご１の外周面から離れるように弾性変形し、第１の隙間閉塞部９ａが換気隙間８の内面に接触して換気隙間８を閉じる。また、第２の水平方向延設部９ｂ１は、乗りかご１の下降時に、第２の上下方向延設部９ｂ２の先端部が乗りかご１の外周面に接触するように弾性変形して換気隙間８を閉じる。 When the ventilation gap closing device 7 is mounted upside down with respect to the above-described embodiment, the deformation and operation of the elastic deformation portion 11, the first gap closing portion 9a, and the second gap closing portion 9b are lowered. And the opposite is true when rising. That is, the attachment portion 11 is elastically deformed so as to move away from the outer peripheral surface of the car 1 when the car 1 is raised, and the first gap closing part 9 a comes into contact with the inner surface of the ventilation gap 8 to close the ventilation gap 8. The second horizontal extending portion 9b1 is elastically deformed so that the tip of the second vertical extending portion 9b2 contacts the outer peripheral surface of the car 1 when the car 1 is lowered. Close 8
　以上説明したように本実施例は、換気隙間８を形成している側板５と床フレーム４の近傍に、乗りかご１の外側に突出し、かつ乗りかご１の昇降時に風圧を受けて弾性的に変形する昇降時風受け部１２と弾性変形部１１とを備える。そして本実施例では、昇降時風受け部１２および弾性変形部１１の弾性変形によって換気隙間８をほぼ塞ぐよう動作する隙間閉塞部９を有する換気隙間封止装置７を構成する。 As described above, in this embodiment, in the vicinity of the side plate 5 and the floor frame 4 forming the ventilation gap 8, the outside of the car 1 protrudes and elastically receives the wind pressure when the car 1 is raised and lowered. An up-and-down wind receiving portion 12 and an elastic deformation portion 11 are provided. In this embodiment, the ventilation gap sealing device 7 having the gap closing portion 9 that operates so as to substantially close the ventilation gap 8 by the elastic deformation of the wind receiving portion 12 and the elastic deformation portion 11 is configured.
　このような構成によれば、乗りかご１が高速で昇降移動（走行）するときに受ける風圧を利用して換気隙間８をほぼ塞ぐように隙間閉塞部９を作動させることができる。従って、簡単な構成で、かつ確実に隙間閉塞部９を作動させることができる。また、乗りかご１の停止状態では換気隙間８を開放状態にすることができる。このため、乗りかご１の高速での昇降時には換気隙間８をほぼ閉塞状態にして、効果的に外部から乗りかご１内への騒音侵入を阻止することができる。 According to such a configuration, the gap closing portion 9 can be operated so as to substantially close the ventilation gap 8 using the wind pressure received when the car 1 moves up and down (runs) at high speed. Therefore, it is possible to operate the gap closing portion 9 with a simple configuration and with certainty. Further, the ventilation gap 8 can be opened when the car 1 is stopped. For this reason, when the car 1 is moved up and down at a high speed, the ventilation gap 8 is almost closed, and noise can be effectively prevented from entering the car 1 from the outside.
　また本実施例は、上述の構成に加えて、弾性変形部は、一端部が固定され、かつ他端部が換気隙間８側に延びた取り付け変形部１１と、取り付け変形部１１と一体的に形成されて乗りかご１の外側に位置し、かつ、乗りかご１の上昇時および下降時に相反する側に風圧を受けて弾性変形する昇降時風受け部１２と、を備える。また、昇降時風受け部１２の先端部（乗りかご１から離れる側の端部）には、昇降時風受け部１２と一体的に形成されて乗りかご１の外側に位置し、かつ、乗りかご１の下降時に効果的に風圧を受けて弾性変形を促す下降時風受け部１３を有する。 Further, in this embodiment, in addition to the above-described configuration, the elastic deformation portion is integrated with the attachment deformation portion 11 having one end fixed and the other end extending toward the ventilation gap 8, and the attachment deformation portion 11. And an up-and-down wind receiving portion 12 that is formed on the outside of the car 1 and elastically deforms by receiving wind pressure on opposite sides when the car 1 is raised and lowered. Further, the tip of the wind receiving portion 12 during lifting (the end portion on the side away from the car 1) is integrally formed with the wind receiving portion 12 during lifting and is located outside the car 1. When the car 1 descends, it has a descending wind receiving portion 13 that effectively receives wind pressure and promotes elastic deformation.
　このような構成によれば、昇降時風受け部１２および下降時風受け部１３によって、乗りかご１における高速での昇降時の風圧を効果的に捉えることができ、確実に隙間閉塞部９を作動させることができる。 According to such a configuration, the wind pressure portion 12 at the time of ascending and descending portion 13 at the time of descending and descending can effectively catch the wind pressure at the time of raising and lowering the car 1 at a high speed, and the gap closing portion 9 can be surely formed. Can be operated.
　上述した実施例では、エレベーター装置の高速化に対応可能な、乗りかご内の騒音低減技術を説明している。本技術の発明時には、乗りかごの速度は１０５ｍ／ｍｉｎ程度であったが、更なる高速化に対応可能であり、１５０ｍ／ｍｉｎ以上の乗りかご速度に対しても乗りかご内の騒音を効果的に低減可能である。 In the above-described embodiment, the noise reduction technology in the car that can cope with the speeding up of the elevator apparatus is described. At the time of inventing the present technology, the speed of the car was about 105 m / min. However, it is possible to cope with further speedup, and the noise in the car is effective even for a car speed of 150 m / min or more. Can be reduced.
　尚、本発明は、上述した実施例に限定するものではなく、様々な変形例が含まれる。例えば、上述した実施例は本発明を分かり易く説明するために詳細に説明したものであり、必ずしも説明した全ての構成を備えるものに限定されるものではない。 In addition, this invention is not limited to the Example mentioned above, Various modifications are included.
