<P>PROBLEM TO BE SOLVED: To provide an elevator apparatus which performs door opening control or door closing prevention control and prevents unnecessary door opening control or door closing prevention control without requiring installation of a special cam on a safety shoe. <P>SOLUTION: The elevator apparatus is configured in such a way that in conjunction with an opening operation of a door 1, a roller 13 disposed on the safety shoe 10 is caused to travel along an inclination part installed independent of the door 1, near full opening position of the door 1 and, thereby, the safety shoe 10 is forcibly retreated. The elevator apparatus includes a lever 16 with inclination which has an inclination surface 16a of a prescribed distance allowing the roller 13 to come in slide contact therewith and which is displaceable in a fixed amount in conjunction with the slide contact of the roller 13, the lever 16 with inclination sets a second detector (18) to be in the detection state when the roller 13 is located on the inclination surface 16a, the second detector (18) detecting forcible retreat of the safety shoe 10, and sets the second detector (18) to be in the non-detection state when the roller 13 is separated from the inclination surface 16a. <P>COPYRIGHT: (C)2012,JPO&INPIT |
