Airfield sign cover
View Patent ↗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.
1 . 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.
2 . The airport sign cover of claim 1 further comprising a plurality of end grommets formed on, or secured to, the cover segment proximal the cover ends; and, an end cord secured to the grommets.
3 . The airport sign of claim 2 further comprising a spherical chord anchor secured to an end of the end cord.
4 . The airport sign cover of claim 3 further comprising a plurality of side grommets formed on or secured to the cover segment proximal the cover sides and a side cord secured to the side grommets.
5 . The airport sign cover of claim 4 further comprising a cord anchor secured to an end of the side cord.
6 . The airport sign of claim 1 further comprising axial end shoulders extending downwardly from axial ends of the upper air-flow segment.
7 . 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.
8 . The airport sign cover of claim 7 further comprising at least one gap stud secured to an inner surface of the cover segment.
9 . The airport sign cover of claim 8 further comprising a plurality of end grommets formed on, or secured to, the cover segment proximal the cover ends; and, an end cord secured to the grommets.
10 . The airport sign cover of claim 9 further comprising a spherical chord anchor secured to an end of the end cord.
11 . The airport sign cover of claim 10 further comprising a plurality of side grommets formed on or secured to the cover segment proximal the cover sides and a side cord secured to the side grommets.
12 . The airport sign cover of claim 11 further comprising a cord anchor secured to an end of the side cord.
13 . 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.
14 . The airport sign cover of claim 13 further comprising at least one gap stud secured to an inner surface of the cover segment.
15 . The airport sign cover of claim 14 further comprising a plurality of end grommets formed on, or secured to, the cover segment proximal the cover ends; and, an end cord secured to the grommets.
16 . The airport sign of claim 15 further comprising a spherical chord anchor secured to an end of the end cord.
17 . The airport sign of claim 16 further comprising a plurality of side grommets formed on or secured to the cover segment proximal the cover sides and a side cord secured to the side grommets.
18 . The airport sign of claim 17 further comprising a cord anchor secured to an end of the side cord.
