As described above, according to the present invention, a car which moves up and down a hoistway and stops at a landing provided on the hoistway, forms a lower edge of the entrance of the car, and has a front edge facing the landing. And a lower edge member having recesses arranged at a plurality of intermediate positions in the entrance width, and one side is provided corresponding to the entrance width and one side is disposed at the front edge of the lower edge member, and the width of the entrance width direction is different. Both ends are pivotally supported by the pivot mechanism, and the transversal board is driven through the pivot mechanism to keep the transversal board in the retracted position at all times. A driving device for displacing the other side to a horizontal position protruding toward the landing side, and a driving plate provided at an edge portion of the crossing plate facing the landing side, disposed at both ends in the width direction of the entrance and exit, and the crossing plate is disposed at the horizontal position. Occasionally a support strip that engages the landing from above and the lower edge of the handover And a pivoting means for pivotally holding the transfer plate to the lower edge member at a position lower than the upper surface of the lower edge member via a convex portion provided at a portion opposed to the lower edge member and fitted into the recess of the lower edge member. It is a thing.

Thus, when the car stops at the landing, the transfer plate is displaced to the horizontal position protruding toward the landing, and the support piece is supported on the upper surface of the lower edge of the landing entrance, and the lower edge of the landing entrance, The plate and the lower edge member of the car doorway are substantially coplanar. Thus, when a wheelchair user or the like uses the elevator, small wheels such as front wheels of the wheelchair do not fall into the gap between the landing and the car, so that the passenger can easily get on and off between the landing and the car. Barrier-free is realized. The transfer plate arranged at the horizontal position is supported on the landing entrance side and the car entrance side by a number of support points by a pivoting mechanism, a pivoting means, and a support piece.
For this reason, the bending caused by the load of the front wheel of the wheelchair or the like is reduced, and there is an effect that the getting on and off the wheelchair or the like is facilitated.

And a slope formed so that the tip side is directed upward and is arranged to face the slope of the lower edge member.

As a result, the slope of the passing plate lowered by the deflection of the passing plate due to the load of the front wheel of the wheelchair or the like is supported by the inclined surface of the lower edge member at the car entrance. Therefore, it is possible to reduce the weight of the handover plate, and to reduce the size of the driving machine based on this lightness reduction, which has the effect of reducing the manufacturing cost of related devices such as the handover plate.

Further, as described above, according to the present invention, a car which moves up and down the hoistway and stops at the landing provided on the hoistway, forms a lower edge of the entrance of the car, and has a front edge facing the landing. And a lower edge member having recesses arranged at a plurality of intermediate positions in the entrance width, and one side is provided corresponding to the entrance width and one side is disposed at the front edge of the lower edge member, and the width of the entrance width direction is different. A transfer plate whose both ends are pivotally supported by a pivot mechanism, a transmission plate and a linear reciprocating operation type in which a center portion is engaged with a shaft of the pivot mechanism and one side is fixed to an edge of the transfer plate near the landing. And a driving device that is connected to the other side of the transmission plate via a link and drives the transmission plate to rotate, and always holds the transfer plate at the lowered and retracted position, and when the car faces the landing, the transmission plate Rotational displacement to a horizontal position where the other side of the handover board projects toward the landing via Via a driving device and a convex portion provided at a portion facing the lower edge member of the transfer plate and fitted into a recess of the lower edge member, to the lower edge member at a position lower than the upper surface of the lower edge member. And a pivoting means for pivoting the board.

Thus, when the car stops at the landing, the crossing board is displaced from the lowered position to the horizontal position protruding toward the landing, and the lower edge of the landing entrance, the crossing board, and the lower edge member of the car entrance are substantially displaced. They are arranged on the same plane. Thus, when a wheelchair user or the like uses the elevator, small wheels such as front wheels of the wheelchair do not fall into the gap between the landing and the car, so that the passenger can easily get on and off between the landing and the car. Barrier-free is realized. The transfer plate disposed at the horizontal position is supported on the car doorway side by a number of support points provided by the pivoting mechanism and the pivoting means. For this reason, the bending caused by the load on the front wheel of the wheelchair or the like is reduced, and there is an effect that the getting on and off the wheelchair or the like is facilitated.
