Abstract
A horizontal door system is used in conjunction with an interfloor vertical transport system that penetrates an opening in a floor. The vertical transport system has vertical elements that define a fixed horizontal cross-section within the opening, and the door system includes a leading edge profile having a configuration matching the fixed horizontal cross-section of the vertical transport system. The door system is particularly suitable as a fire door system to seal upper and lower fire zones.
Claims38
An interfloor vertical transport and horizontal closure system comprising:
- a vertical transport system extendable through an opening in a floor or ceiling, the vertical transport system comprising vertical elements defining a fixed horizontal cross-section within the opening;
- and
- a horizontal door system operative to seal the opening in the floor or ceiling comprising a door assembly comprising a frame mountable adjacent the opening surrounding the vertical transport system and a door movably mounted to the frame to travel in a horizontal plane to seal the opening in the floor, the door including a leading edge profile having a configuration matching a configuration of an opposed portion of the fixed horizontal cross-section of the vertical elements of the vertical transport system, the door oriented horizontally with the leading edge profile disposed in opposition to the opposed portion of the fixed horizontal cross-section.
An interfloor vertical transport and horizontal closure system comprising:
- a vertical transport system extendable through an opening in a floor or ceiling, the vertical transport system comprising a drive column comprising vertical elements defining a fixed horizontal cross-section within the opening, the vertical transport system further comprising a robot assembly operable to travel vertically along the drive column;
- and
- a horizontal door system operative to seal the opening in the floor or ceiling comprising a door assembly comprising a frame mountable adjacent the opening surrounding the vertical transport system and a door movably mounted to the frame to seal the opening in the floor, the door including a leading edge profile having a configuration matching a configuration of an opposed portion of the fixed horizontal cross-section of the vertical elements of the drive column.
An interfloor vertical transport and horizontal closure system comprising:
- a vertical transport system extendable through an opening in a floor or ceiling, the vertical transport system comprising vertical elements defining a fixed horizontal cross-section within the opening;
- and
- a horizontal door system operative to seal the opening in the floor or ceiling comprising:
- a door assembly comprising a frame mountable adjacent the opening surrounding the vertical transport system and a door movably mounted to the frame to seal the opening in the floor, the door including a leading edge profile having a configuration matching a configuration of an opposed portion of the fixed horizontal cross-section of the vertical transport system,
- a plenum mounted to the door assembly and suspended to depend below the opening in the floor or ceiling, and
- a lower door assembly connected to a lower end of the plenum and including a door movably mounted to close a lower end of the plenum.
An interfloor vertical transport and horizontal closure system comprising:
- a vertical transport system extendable through an opening in a floor or ceiling, the vertical transport system comprising vertical elements defining a fixed horizontal cross-section within the opening;
- and
- a horizontal door system operative to seal the opening in the floor or ceiling comprising a door assembly comprising:
- a frame mountable adjacent the opening surrounding the vertical transport system,
- a first door movably mounted to the frame to seal the opening in the floor, the first door including a leading edge profile having a configuration matching a configuration of an opposed portion of the fixed horizontal cross-section of the vertical transport system, and
- a second door movably mounted to the frame in opposition to the first door, the first door and the second door disposed to converge around the vertical transport system.
