Rail system for elevator sliding doors

摘要

The system (1) has two guide rails (25) adjacently arranged regarding opening and closing directions and connected with each other by connectors (2). An inner lying carriage (5) is guided to a small roller (7), and an outer carriage (6) is guided to a larger roller (8). The connectors are accommodated in a space above the small roller. The connectors are arranged such that the small roller rolls under or rolls over the connectors in the course of the opening or closing movement of the roller, while large roller laterally passes the mentioned connectors. An independent claim is also included for a connector system for provision of a connector for a lift-door guidance system.
