　図において、かご出入口１の上方には、ドア装置筐体２が固定されている。 In the figure, a door device housing 2 is fixed above the car doorway 1.
　ドア装置筐体２には、かご出入口１の間口方向に沿って延びるドアレール３が固定されている。 A door rail 3 is fixed to the door device casing 2 so as to extend along the entrance direction of the car doorway 1.
　かご出入口１は、一対のドア本体４がドアレール３によって案内されて水平方向に変位することで開閉される。 The car doorway 1 is opened and closed by a pair of door main bodies 4 being guided by the door rails 3 and being displaced in the horizontal direction.
　一対のドア本体４はそれぞれ、ドアパネル５と、このドアパネル５の上端部に固定されたドアハンガ６と、このドアハンガ６に設けられドアレール３に沿って転動される複数のハンガローラ７とを有して構成されている。 Each of the pair of door bodies 4 includes a door panel 5, a door hanger 6 fixed to the upper end portion of the door panel 5, and a plurality of hanger rollers 7 provided on the door hanger 6 and rolled along the door rail 3. It is configured.
　ドア本体４は、ドア装置に搭載されたドアモータの駆動力によって開閉される。 The door body 4 is opened and closed by the driving force of a door motor mounted on the door device.
　各ドア本体４の下端部には、複数の戸の脚２３が取り付けられており、この戸の脚２３は、ドアパネル５の背面下部に固定された補強部材（図示せず）に固定されている。 A plurality of door legs 23 are attached to the lower end of each door body 4, and the door legs 23 are fixed to a reinforcing member (not shown) fixed to the lower back of the door panel 5. .
　また、かご出入口１の床部には、かご出入口１の間口方向に沿って延設させるかご敷居９が固定されており、このかご敷居９には、戸の脚２３が挿入されて各ドア本体４の下端部の開閉を案内する敷居溝９ａが設けられている。 Further, a car sill 9 extending along the frontage direction of the car doorway 1 is fixed to the floor of the car doorway 1. A door leg 23 is inserted into the car sill 9 so that each door main body is inserted. 4 is provided with a threshold groove 9a for guiding opening and closing of the lower end portion.
　また、ドア本体４の下端部には、戸閉状態のときにドア本体４の下端部とかご敷居９との間の隙間を密封する下部遮蔽体１９が上下動可能に設けられており、この下部遮蔽体１９は、可動板２０と、可動板２０の下端部に固定されかご敷居９に接離するシール部材２１とを有している。 In addition, a lower shield 19 that seals the gap between the lower end of the door body 4 and the car sill 9 when the door is closed is provided at the lower end of the door body 4 so as to be movable up and down. The lower shield 19 includes a movable plate 20 and a seal member 21 that is fixed to the lower end portion of the movable plate 20 and contacts and separates from the car sill 9.
　シール部材２１は、たとえばゴム又は樹脂等の弾性体からなり、ドア本体４の幅方向全体に渡って延びており、敷居溝９ａよりもかご側でかご敷居９の上面に接離する。 The seal member 21 is made of, for example, an elastic body such as rubber or resin, and extends over the entire width direction of the door body 4, and comes in contact with and separates from the upper surface of the car sill 9 on the car side with respect to the sill groove 9 a.
　次に、動作について説明する。 Next, the operation will be described.
　戸閉状態のときには、左右両ドアの押圧部１０がお互いに戸閉動作によって押圧し合い、押圧部１０に取り付けられたバー１１が、スライド機構１２によって間口方向に水平に移動する。 When the door is closed, the pressing portions 10 of the left and right doors are pressed against each other by the door closing operation, and the bar 11 attached to the pressing portion 10 is moved horizontally in the frontage direction by the slide mechanism 12.
　このバー１１の水平移動によって、レバー１３が回転中心１３ａを中心に反時計方向に回転し、このレバー１３の回転によって、レバー１３に連結されたバー１４はかご出入口１の方向(図２中左側)に移動する。 The horizontal movement of the bar 11 causes the lever 13 to rotate counterclockwise around the rotation center 13a, and the rotation of the lever 13 causes the bar 14 connected to the lever 13 to move toward the car entrance 1 (left side in FIG. 2). )
　そしてこのバー１４の移動によって、レバー１５は回転中心１５ａを中心に時計方向に回転し、レバー１５に連結されたバー１６が下降する。 Then, by the movement of the bar 14, the lever 15 rotates clockwise around the rotation center 15a, and the bar 16 connected to the lever 15 descends.
　次に、バー１６が下降することによって、バー１６に連結された可動板２０が、スライド機構２２に沿って下降し、この可動板２０が下降することによって、可動板２０に固定されたシール部材２１も下降し、かご敷居９に押し付けられる。 Next, when the bar 16 is lowered, the movable plate 20 connected to the bar 16 is lowered along the slide mechanism 22, and when the movable plate 20 is lowered, the seal member fixed to the movable plate 20. 21 also descends and is pressed against the car sill 9.
　ここで、シール部材２１がかご敷居９に押し付けられることによって、ドア本体４の下端部とかご敷居９との隙間が密封される。 Here, when the sealing member 21 is pressed against the car sill 9, the gap between the lower end of the door body 4 and the car sill 9 is sealed.
　また、バー１６が下降することによって、バー１６に連結されたレバー１７が、回転中心１７ａを中心に反時計方向に回転し、このレバー１７の回転によって、レバー１７に連結された釣り合い錘１８が上昇する。 Further, when the bar 16 is lowered, the lever 17 connected to the bar 16 rotates counterclockwise about the rotation center 17a, and the counterweight 18 connected to the lever 17 is rotated by the rotation of the lever 17. To rise.
　この戸閉状態から、ドア本体４の戸開動作が開始されると、押圧されていた押圧部１０の押圧状態が非押圧状態となる。 When the door opening operation of the door body 4 is started from this door closed state, the pressed state of the pressing portion 10 that has been pressed becomes a non-pressed state.
　これにより、レバー１７は、釣り合い錘１８の自重による下降によって、回転中心１７ａを中心に時計方向へ回転し、このレバー１７の回転によってレバー１７に連結されたバー１６が上昇する。 Thereby, the lever 17 is rotated clockwise around the rotation center 17 a by the lowering of the counterweight 18 due to its own weight, and the bar 16 connected to the lever 17 is raised by the rotation of the lever 17.
　そして、バー１６が上昇することにより、バー１６に連結されている可動板２０が上昇し、この可動板２０が上昇することにより、可動板２０に固定されているシール部材２１が上昇する。 When the bar 16 is raised, the movable plate 20 connected to the bar 16 is raised, and when the movable plate 20 is raised, the seal member 21 fixed to the movable plate 20 is raised.
　なお、本発明でいう連動機構８は、上述した通り、戸閉状態のときに下部遮蔽体１９を下降させ、戸開状態のときに下部遮蔽体１９がかご敷居９から開離するように、下部遮蔽体１９を上下動させる連動機構であり、具体的には、押圧部材１０の変位に応じて水平移動するバー１１と、このバー１１の水平移動を案内するスライド機構１２と、前記バー１１の水平移動に応じて回転中心１３ａを中心に反時計方向に回転するレバー１３と、このレバー１３の回転によってかご出入口１の方向(図２中左側)に移動するバー１４と、このバー１４の移動によって回転中心１５ａを中心に時計方向に回転するレバー１５と、このレバー１５の回転に応じて下降し下部遮蔽体１９をかご敷居９に当接させるバー１６と、このバー１６が下降することによって回転中心１７ａを中心に反時計方向に回転し連結された釣り合い錘１８を上昇させるレバー１７とを備えて形成されている。 As described above, the interlocking mechanism 8 according to the present invention lowers the lower shield 19 when the door is closed, and the lower shield 19 is separated from the car sill 9 when the door is open. This is an interlocking mechanism that moves the lower shield 19 up and down. Specifically, the bar 11 moves horizontally according to the displacement of the pressing member 10, the slide mechanism 12 that guides the horizontal movement of the bar 11, and the bar 11. A lever 13 that rotates counterclockwise around the rotation center 13a according to the horizontal movement of the bar, a bar 14 that moves in the direction of the car doorway 1 (left side in FIG. 2) by the rotation of the lever 13, and The lever 15 that rotates clockwise around the rotation center 15a by the movement, the bar 16 that descends in accordance with the rotation of the lever 15 and makes the lower shield 19 contact the car sill 9, and the bar 16 descends Thus is formed a lever 17 for raising the around the rotation center 17a rotates counterclockwise linked counterweight 18.
　このように本発明のかごドア装置によれば、押圧部１０の移動と釣り合い錘１８の上下動を利用して下部遮蔽体１９を上下動作させることができるので、ドア本体４の開閉動作性能を維持しつつ、戸閉状態でドア本体４の下端部とかご敷居９との隙間を確実に密封することができる。 As described above, according to the car door device of the present invention, the lower shield 19 can be moved up and down by using the movement of the pressing portion 10 and the vertical movement of the counterweight 18. While maintaining the door, the gap between the lower end of the door body 4 and the car sill 9 can be reliably sealed when the door is closed.
　従って、気密性・遮煙性・遮音性・遮光性を高めることができる。 Therefore, airtightness, smoke insulation, sound insulation, and light shielding can be improved.
　さらに、押圧部１０は、ドア本体４が完全戸閉位置から所定の範囲内にあるときのみ稼動し、かご敷居溝９ａ内に位置するので、ドア本体４の動作に対して下部遮蔽体１９の動作を小さく抑えることができる。 Further, the pressing portion 10 operates only when the door body 4 is within a predetermined range from the fully closed position, and is located in the car sill groove 9a. The operation can be kept small.
　また、下部遮蔽体１９の昇降動作のためにモータ等の専用の駆動源を用いる必要が無く、コストを低減できる。 Further, it is not necessary to use a dedicated drive source such as a motor for the raising / lowering operation of the lower shield 19, and the cost can be reduced.
　さらに、下部遮蔽体１９は鉛直方向に昇降されるので、ドア本体４の幅方向全体に渡って下部遮蔽体１９を設けることができ、また、下部遮蔽体１９がその変位に伴ってドア本体４の幅方向端部から突出するのを防止できる。 Further, since the lower shield 19 is lifted and lowered in the vertical direction, the lower shield 19 can be provided over the entire width direction of the door body 4, and the lower shield 19 is moved along with the displacement of the door body 4. It can prevent protruding from the width direction edge part.
　このように、乗客から見えない位置である敷居溝９ａ内に押圧部１０を設け、同じく乗客から見えない位置であるドア本体４の内部に連動機構８と、下部遮蔽体１９および釣り合い錘１８とを設けることによって、意匠を損ねることなく、戸閉時にドア本体４の下端部とかご敷居９との隙間を密封することができる。 Thus, the pressing portion 10 is provided in the sill groove 9a that is not visible to the passenger, and the interlocking mechanism 8, the lower shield 19, and the counterweight 18 are provided inside the door body 4 that is also invisible to the passenger. By providing this, the gap between the lower end of the door body 4 and the car sill 9 can be sealed when the door is closed, without impairing the design.
　また、シール部材２１を弾性体で構成したので、製作誤差や据付誤差を弾性体の弾性変形により吸収させることができ、シール部材２１をかご敷居９に密着させることができる。 Further, since the seal member 21 is made of an elastic body, manufacturing errors and installation errors can be absorbed by elastic deformation of the elastic body, and the seal member 21 can be brought into close contact with the car sill 9.
　また、バー１６は上下方向のみではなく回転方向へ可動するため、ドア本体４の下端部とかご敷居９との隙間のばらつきに対して、下部遮蔽体１９の昇降ストロークの微調整が可能であり、かつその調整作業が容易である。 Further, since the bar 16 is movable not only in the vertical direction but also in the rotational direction, the vertical stroke of the lower shield 19 can be finely adjusted with respect to the variation in the gap between the lower end of the door body 4 and the car sill 9. And the adjustment work is easy.
　さらにまた、釣合い錘１８の昇降領域をドアパネル５の内側に収め、下部遮蔽体１９及び連動機構８をドアパネル５の下端部付近に配置することができるので、全体をコンパクトに構成でき、ドアパネル５にカバーが設けられている製品やドアパネル５に補強部材が固定されている製品にも容易に適用することができる。 Furthermore, since the raising / lowering region of the counterweight 18 can be housed inside the door panel 5 and the lower shield 19 and the interlocking mechanism 8 can be disposed near the lower end of the door panel 5, the entire structure can be made compact. The present invention can be easily applied to a product in which a cover is provided and a product in which a reinforcing member is fixed to the door panel 5.
　次に、図５はこの発明の第２の実施例によるエレベーターかごドア装置の要部を示す拡大図である。 Next, FIG. 5 is an enlarged view showing a main part of an elevator car door device according to a second embodiment of the present invention.
　戸閉状態のときには、左右両ドアの押圧部１０がお互いに戸閉動作によって押圧し合い、押圧部１０に取り付けられたレバー２４が、回転中心２４ａを中心に反時計方向に回転する。 When the door is closed, the pressing portions 10 of the left and right doors are pressed against each other by the door closing operation, and the lever 24 attached to the pressing portion 10 rotates counterclockwise around the rotation center 24a.
　レバー２４の回転によって、レバー２４に連結されたバー１４はかご出入口１の方向に移動する。他の構成は、実施例１と同様である。 Rotation of the lever 24 moves the bar 14 connected to the lever 24 in the direction of the car doorway 1. Other configurations are the same as those of the first embodiment.
　前記のように連動機構８にスライド機構を用いない構造とすることにより、かごの戸の軽量化及び材料コストの低減を図ることができる。 As described above, the structure that does not use the slide mechanism for the interlocking mechanism 8 can reduce the weight of the car door and reduce the material cost.
　また、レバー２４の回転運動は水平運動と比較して高い精度を必要としないことから、製作誤差や据付誤差による影響を小さくすることができる。 Also, since the rotational movement of the lever 24 does not require high accuracy compared to the horizontal movement, it is possible to reduce the influence due to manufacturing errors and installation errors.
