Abstract
A door guide assembly for an elevator cab includes a gib bracket and a sill having a guide groove in the face of the sill. The guide bracket extends down from the door and into the guide groove to guide the motion of the door. The guide groove includes a narrow opening and an expanded section inward of the opening. Engagement between the narrow opening and the gib bracket prevents excessive vertical movement of the door and engagement between the expanded section and the gib bracket prevents excessive lateral motion of the door.
