<p><P>PROBLEM TO BE SOLVED: To prevent a guide shoe installed to a sliding door from coming off from a guide groove of a sill without increasing the strength and rigidity of the sliding door, and to facilitate the fitting work and detaching work of the guide shoe to/from the guide groove. <P>SOLUTION: This guide device of an elevator sliding door includes a guide shoe 2 installed at a lower edge of a slidable sliding door 1 opening and closing a doorway of an elevator, and a guide groove 5 formed at a sill 4 of the doorway for slidably fitting the guide shoe 2 thereto. The guide groove 5 includes a wide part 6 whose lateral width dimension in a plane perpendicular to its longitudinal direction is large, and a narrow part 7 which is positioned above the wide part 6 and whose lateral width dimension is smaller than that of the wide part 6. The guide shoe 2 includes a come-off prevention part 8 which is fitted to the wide part 6 and whose lateral width dimension in a plane perpendicular to a longitudinal direction of the guide groove 5 is larger than that of the narrow part 7. An opening hole 61 having an area larger than a projection area of the guide shoe 2 is formed at a part of a bottom face of the guide groove 5, and the guide shoe 2 is detachably mounted to the sliding door 1. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
