Summary:EVEN IF RELATIVE DISPLACEMENT BETWEEN AN NTH FLOOR AND AN (N+1)TH FLOOR CAUSED BY THE ACTION OF A SEISMIC ISOLATION DEVICE (8) CAUSES SIGNIFICANT DEFORMATION OF GUIDE RAILS (3, 4) AT THE OCCURRENCE OF AN EARTHQUAKE, ELEVATOR HALL DOORS (9) ON THESE FLOORS ARE ROTATED AROUND A FLOOR SIDE JOURNALING MEMBER (10) AND A CEILING SIDE JOURNALING MEMBER (11), AND CHANGE THE POSITIONS THEREOF TO FOLLOW HORIZONTAL DISPLACEMENT OF THE GUIDE RAILS (3, 4). THIS CAN PREVENT A SIGNIFICANT CHANGE IN DISTANCE BETWEEN THE GUIDE RAIL (3) AND THE ELEVATOR HALL DOOR (9), MINIMIZE A REDUCTION IN USABLE FLOOR AREAS IN A BUILDING, AND PREVENT COMPLICATION OF MOUNTING STRUCTURES OF CONFIGURATION MEMBERS.
