Abstract
A modular airfield sign cover having a sheet with ends formed with eyelets and dedicated end-securing bungee cord like securing laces with an enlarged ball to secure the cover ends. Zippered halves or grommet/cord combinations secured to each side permit the sides to be folded and secured together to encapsulate an airfield sign in the cover. An air gap formed at a top edge of an enclosed airfield sign permits airflow between the cover and sign. Air-flow frames formed on or secured to an inner surface of the cover engage a sign and include air-flow slots to permit air entering the air gap to flow down over the sign sides. Air-gap studs secured to the inner surface of the cover space the cover from the sign sides to allow air to freely pass over the sign.
Claims18
An airport sign cover comprising:
- a cover segment having an inner surface and an outer surface and having two sides and two ends;
- a pair of air-flow frames defining at least one air gap, and secured to the inner surface of the cover segment, and spaced about a center line of the cover segment, wherein each of the pair of air-flow frames comprises an elongate upper air-flow segment with a first shoulder extending downwardly from, and proximal to, a distal lateral end of the upper air-flow segment and a second shoulder extending downwardly from the upper air-flow segment at a position laterally inwardly from the first shoulder segment and at least one air-gap slot formed in the upper air-flow segment between an inner surface of the first shoulder and an outer surface of the second shoulder;
- and,
- at least one gap stud secured to an inner surface of the cover segment.
An airport sign cover comprising:
- a cover segment having an inner surface and an outer surface and having two sides and two ends;
- and,
- a pair of air-flow frames defining at least one air gap, and secured to the inner surface of the cover segment, and spaced about a center line of the cover segment, wherein each of the pair of air-flow frames comprises an elongate upper air-flow segment with a shoulder extending downwardly from, and distal to, a lateral end of the upper air-flow segment and at least one air-gap slot formed in the upper air-flow segment between the lateral end and an outer surface of the shoulder.
An airport sign cover comprising:
- a cover segment having an inner surface and an outer surface and having two sides and two ends;
- and,
- a pair of air-flow frames defining a plurality of air gaps, and secured to the inner surface of the cover segment, and spaced about a center line of the cover segment, wherein each of the pair of air-flow frames comprises an elongate upper air-flow segment with a shoulder extending downwardly from, and distal to, a distal lateral end of the upper air-flow segment, at least one air-gap slot formed in the upper air-flow segment between the distal lateral end and an outer surface of the shoulder and axial end shoulders extending downwardly from axial ends of the upper air-flow segment.
