A safety curtain and system includes multiple light emitters and multiple light receivers to detect traffic approaching a doorway. The safety curtain my include pairs of multiple light emitters and receivers positioned on both sides of a passageway (doorway) so as to detect approaching traffic. The multiple light emitters and light receivers may detect a height of an approaching traffic (e.g., person or vehicle) and initiate warning lights of a possible door closing. The detected approach of traffic may cause the door to be stopped, reversed or slow down. The system may include a computer to monitor the signals from the receivers and may control the motion of the door.

System and method for safety management in roll-up doors

An overhead roll-up door assembly having a door controller, a door panel and a drum on which the door panel is wound and unwound to open and close a doorway, opening and closing of the door being controlled by the controller. The door assembly includes a safety system comprising at least one light, the at least one light being positioned to emit light proximate a first side of the doorway, the light from the at least one light being projected onto a lower boundary of the doorway and forming a strip or stripe proximate the first side of the doorway, wherein emission of the light from the at least one light is controlled by the controller in conjunction with the controller opening and closing the doorway.

Safety system and method for overhead roll-up doors

The present invention is directed to an industrial high-speed door assembly having a reduced door panel width and having guides for guiding the door which extend into a passageway but are resilient, tough, or resiliently collapsible, to either withstand impacts from vehicle collisions or moveable during opening of the door to avoid collisions while returning for guidance upon closing the door.

High speed door assembly

A door assembly comprising a door body having a bottom edge is disclosed. The door body is selectively movable up and down to open and close an opening. The door assembly further comprises a safety edge attached to the bottom edge of the door body, the safety edge being an extrudate extruded from a deformable material and comprising a first and second chamber formed in integrated cooperative redundancy in the extrudate, wherein the first chamber comprises a first sensor body and the second chamber comprises a second sensor body, each sensor body being responsive to an impact.

Dual safety-edge for an overhead door

A door assembly comprising a door body having a bottom edge. The door body is selectively movable up and down to open and close an opening. The door assembly further comprises a first sensor body and a second sensor body. Each sensor body is in communication with a door controller, and each sensor body has an impact portion responsive to an impact proximate the bottom edge of the door body.
