【0013】以上のエプロン動作機構16の電気的ブロック回路を図5に示し、そのフローチャートを図6に示している。 [0013] The electrical block circuit of the above apron operation mechanism 16 shown in FIG. 5 shows the flow chart in FIG. なお前述の如くウインチ19等の異常発生で電磁クランプ23が開放動作すると、その電磁クランプ制御部から故障信号がエレベータのメインの運転制御装置に送られて、補修のためにエレベータ運転が停止されるようになっている。 Note the electromagnetic clamp 23 at occurrence of an abnormality such as a winch 19 as described above opens operation, fault signal from the electromagnetic clamping control unit is sent to the main operation control device for an elevator, the elevator operation is stopped for repair It has become way.

【0014】しかして、前述の構成のエレベータであれば、かご10が目的階に停止するなど、かご10の走行速度が所定以下になった時は、エプロン動作機構16の速度検知器21からの信号でモータ制御器22がウインチ19のモータをロープ巻き戻し方向に回転制御して、 [0014] Thus, if the elevator configuration described above, the car 10 and stops the destination floor, when the running speed of the car 10 reaches a predetermined or less, from the speed detector 21 of the apron operation mechanism 16 motor controller 22 rotates the control in the direction unwinding the rope a motor winch 19 with signals,
エプロン14をスプリング17の付勢で図1に示す如くかご10の出入口12の敷居13先端下側に略垂直に迫り出す状態に開く、これで該エプロン14が従来同様に本来の転落防止機能を持ち、かご10が万一大きな着床誤差を持って停止した場合でも、該エプロン14が乗場出入口の敷居と該かご10の底部との間の開口を塞ぐようになり、乗客等の昇降路内への転落事故を確実に防止するようになる。 Opening the apron 14 substantially vertically pushed out state biased to the threshold 13 distal lower side of the doorway 12 of the cage 10 as shown in Figure 1 of the spring 17, which in the apron 14 is a conventional Similarly original fall prevention function have, even if the car 10 has stopped with great implantation error event, the apron 14 is turned so as to close the opening between the bottom of the sill and the car 10 of landing doorway, such as a passenger hoistway I would like to reliably prevent the fall accident to.

【0015】一方、かご10が次の目的階に向かって発進して、そのかご10の走行速度が所定以上になると、 Meanwhile, the car 10 is started moving toward the next destination floor, when the running speed of the car 10 reaches or exceeds a predetermined,
速度検知器21からの信号でモータ制御器22がウインチ19のモータをロープ巻き上げ方向に回転制御して、 Motor controller 22 by a signal from the speed detector 21 is rotated controlled motor to rope winding direction of the winch 19,
エプロン14をスプリング17に抗し図2に示す如くかご10の底部方に後退すべく斜め後方に傾斜して整流板11の前端と接合する状態に閉じる。 Close apron 14 in a state of joining the front end of the current plate 11 is inclined obliquely rearward so as to retract the bottom side of the basket 10 as shown in FIG. 2 against the spring 17. これでそのエプロン14はかご10の走行に伴う風音発生の原因とならず、整流板11の一部として機能し、かご走行中の騒音レベルが大幅に低下し、非常に静かなかご走行が可能となる。 This thereof apron 14 does not become a cause of wind noise occurs due to the travel of the car 10, and functions as a portion of the current plate 11, the noise level in the car running is greatly reduced, a very quiet car travel It can become.

【0016】なお、本発明のエレベータは前述の実施例のみに限定されることなく、例えば、エプロン動作機構16はウインチ19以外にエアシリンダなど各種の駆動手段を用いても可である。 [0016] Incidentally, the elevator of the present invention is not limited only to the above embodiments, for example, apron operation mechanism 16 is also acceptable with various drive means such as an air cylinder in addition to the winch 19. またリミッタスイッチ24もエプロン14の開閉状態が検知できればその他の各種検知器を用いても可である。 Further it is also acceptable to use other various detectors if the detection open or closed state of the limiter switch 24 also apron 14. 更には整流板11を設けない場合などでは、かご走行速度が所定以上の時にエプロン14をかご10の底部に接合するまで大きく跳ね上げ回動する如く後退させても可である。 Furthermore in such case without the rectifying plate 11, it is also acceptable by as retracted to increase splashing pivoted to the car speed is bonded to the bottom of the basket 10 the apron 14 when more than a predetermined. その他本発明の要旨を逸脱しない範囲であれば種々変更しても良い。 As long as it does not depart from the spirit of the other present invention may be variously modified.
