Abstract

<P>PROBLEM TO BE SOLVED: To provide a landing device of an elevator for a base isolation building provided with a getting on/off passage between a base entrance of a base construction body and a hoistway entrance of a hoistway, and making the getting on/off passage cope with the relative displacement to the direction of opening of the base entrance and the hoistway entrance without any problem in the earthquake. <P>SOLUTION: A hoistway sidewall plate 18 and the like of the getting on/off passage 7 is rotated to a side edge part of the entrance to cope with the displacement of the base entrance and the hoistway entrance, when the base entrance 3 and the hoistway entrance 4 are displaced in the direction of opening. When a hoistway sidewall plate 18 and the like is over-rotated, a clearance is formed with respect to a rotating plate 22 by the rotational displacement against the energizing force of an energizing body 24. Whereby the excess load does not act on related members in over-rotation of the hoistway sidewall plate 18 and the like, and members of the getting on/off passage 7 can cope with the relative displacement of the base entrance and the hoistway entrance. Accordingly, the operation of the elevator can be easily restarted after the earthquake, and the maintenance cost can be reduced. <P>COPYRIGHT: (C)2004,JPO

In this way, when both the base entrance 3 and the hoistway entrance 4 of the hoistway 2 are relatively displaced in the frontage direction due to an earthquake or the like, the access passage 7 provided between the base entrance 3 and the hoistway entrance 4 is rotated by the rotating plate 22. The above-mentioned components can be easily dealt with relative displacement without causing harmful deformation. For this reason, the operation of the elevator can be restarted after the earthquake without the need for complicated operations, and the maintenance cost can be reduced.

【The invention's effect】
As described above, the present invention, a base-isolated building supported on a base building via a seismic isolation device, a hoistway provided on the base-isolated building and opposed to the base building, A lift passage provided between the base building and the hoistway, a hoistway entrance provided in the hoistway and forming one side of the lift passage, and another side of the lift passage provided in the base building and formed A base entrance / exit; a base side wall plate pivotally connected to a side edge of the base entrance / exit via a vertical axis to project toward the hoistway entrance / exit to form a base entrance / exit side wall surface of the entrance / exit passage; and a hoistway entrance / exit side. One side is arranged at the edge and protrudes toward the base entrance and overlaps with the base side wall plate to form a wall surface on the entrance / exit side of the hoistway entrance / exit passage, and is engaged with the base side wall plate toward the frontage direction of the entrance / exit passage. Hoistway side wall plate with restrained displacement, and one side edge of hoistway entrance The mounting bracket mounted on the other end of the mounting bracket is pivotally connected to the other side of the mounting bracket via a vertical axis, and the other side is overlapped and arranged on the edge surface of the hoistway side wall plate near the hoistway entrance. Plate, one end of which is fixed to the rotating plate, a mounting rod which is inserted into the hoistway side wall plate with a gap formed therebetween, and a rotating plate which is engaged with the other end of the mounting rod to turn the rotating plate to the hoistway side wall plate. And a biasing body for biasing in a pressing direction.
[0025]
As a result, a boarding / alighting passage formed between the base entrance and the entrance / exit of the hoistway is formed with the base side wall plate, the hoistway / sidewall plate, and the rotating plate as main parts. Then, in the event of a horizontal deformation of the seismic isolation device during an earthquake or strong wind, when the base building and the base-isolated building are relatively displaced, between the base building, that is, the base entrance, and the hoistway entrance, that is, the hoistway. When the relative displacement in the frontage direction of the entrance / exit passage occurs, the base side wall plate and the hoistway side wall plate forming the entrance / exit passage are displaced, and rotate with respect to the side edge of the entrance / exit and the base building and the hoistway. Corresponds to the relative displacement of Further, when the hoistway side wall plate or the like is excessively rotated with respect to the side edge portion of the hoistway entrance / exit, the hoistway side wall plate turns against the urging force of the urging body, and A gap is generated between the rotating plate and the rotating plate. For this reason, an excessive load does not act on the hoistway side wall plate and the rotating plate when the hoistway side wall plate and the like are excessively rotated. Therefore, when both the base entrance and the hoistway entrance are relatively displaced in the direction of the entrance frontage due to an earthquake or the like, the above-mentioned relative displacement is normally dealt with without causing harmful deformation of the constituent members of the entrance passage. For this reason, the operation of the elevator can be restarted after the earthquake without complicated operations, and the maintenance cost can be reduced.
