Elevator door sill with hidden guide

摘要

The system has a door with two movably suspended, relatively telescopic door panels glided at the bottom by several mutually independent covered guides. It has a guide groove that is open only to the shaft that guides the lower end of a faster door panel, whilst another guide groove is open towards the floor of the story or cabin and guides the lower end of a slower door panel. An independent claim is also included for a door sill for an elevator door system.
