Problems solved by technology

[0006] However, in the above-mentioned conventional elevator apparatus, there is a problem that when the safety shoes retreat, the impact force generated by the contact between the stopper and the end of the rod is large, and it is necessary to detect whether the safety shoes have moved backward. The stroke of the second detector after the action is too large, and it is difficult to adjust the stroke

Abstract

The invention provides an elevator device situated near a door full open position and forcing a safety shoe to retreat smoothly. The elevator device is equipped with a roller 15 provided on the safety shoe 10, a bracket 13 installed separately from an elevator door 1 and having an inclined surface with which the roller 15 may be in sliding contact, and a second detector 14 operated by a cam 16 disposed parallel with the inclined surface for detecting forced retreat of the safety shoe 10. The inclined surface of the bracket 13 is used to cause forced retreat motion of the safety shoe 10 and an inclined surface of the cam 16 is used to cause detection operation of the second detector 14 for detecting the forced retreat of the safety shoe 10.

Description

technical field [0001] The present invention relates to an elevator installation, and more particularly to an elevator installation having a safety shoe arranged to protrude from a front edge of a door. Background technique [0002] As everyone knows, in the elevator door, as one of the safety devices, a safety shoe that can protrude from the front edge of the door is provided, and through the contact of the safety shoe with the passenger, the safety shoe is retreated, and the opening control of the door (or control that prevents the door from closing). [0003] In general, when the elevator door is fully open, the safety shoes protrude from the front edge of the door, so there is a problem that the luggage, etc. may come into contact with the safety boots when the luggage, etc. is loaded in and unloaded. Deform the safety boots and malfunction. [0004] For this reason, as a conventional technique, an elevator apparatus that forcibly retracts safety shoes in the vicinity ...
