Flexible rack-mounted cabinet-mounted cabinet covering structure for increasing airflow while allowing placement of non standard size equipment

A system for obstructing apertures in a attached rack comprising:

• an upper covering structure for covering an upper opening in the attached rack and comprising a first upper side covering and a second upper side covering, the first upper side covering coupling to a first portion of the attached rack, the second upper side covering coupling to a second portion of the attached rack, the first upper side covering comprising a first upper side rollable rectangular layer configured to extend and retract from the first portion of the attached rack, the second upper side covering comprising a second upper side rollable rectangular layer configured to extend and retract from the second portion of the attached rack, the first upper side rollable rectangular layer and the second upper side rollable rectangular layer configured to couple to each other when in a first extended state so as to covering the upper opening, and a lower covering structure for covering a lower opening in the attached rack, the lower opening being immediately below the upper opening, the lower covering structure comprising a first lower side covering and a second lower side covering, the first lower side covering coupling to the first portion of the attached rack, the second lower side covering coupling to the second portion of the attached rack, the first lower side covering comprising a first lower side rollable rectangular layer configured to extend and retract from the first portion of the attached rack, the second lower side covering comprising a second lower side rollable rectangular layer configured to extend and retract from the second portion of the attached rack, the first lower side rollable rectangular layer and the second lower side rollable rectangular layer configured to couple to each other when in a second extended state so as to covering the lower opening.

A flexible attached rack covering structure for increasing heatflow and maintain enough flexibility to adapt other non-standard size equipment in the rack:

• a first side covering comprising:
• a first tightener and a first rollable rectangular layer (208) comprising a first lateral side,
• a first medial side opposite the first lateral side,
• a first top side,
• a first bottom side opposite the first top side and adjacent the first lateral side and the first medial side,
• the first medial side comprising a first fastener, the first tightener coupled to the first rollable rectangular layer at or near the first lateral side, the first tightener comprising a first tightener height that is less than a first sheet height between the first top side and the first bottom side,
• the first top side is foldable along a first top fold line extending a first length of the first reliable rectangular layer, the first bottom side is foldable along a first bottom fold line extending the first length, a first distance between the first top fold line and the first bottom fold line being substantially equal to the first tightener height, and
• a first op fastener and a first bottom fastener, the first top fastener positioned above the first top fold line, the first bottom fastener positioned above the first bottom fold line,
• a second side covering comprising a second tightener and a second rollable rectangular layer comprising:
• a second lateral side,
• a second medial side opposite the second lateral side,
• a second top side,
• a second bottom side opposite the second top side and adjacent the second lateral side and the second medial side,
• the second medial side comprising a second fastener configured to couple with the first fastener, the second tightener coupled to the second rollable rectangular layer at or near the second lateral side, the second tightener comprising a second tightener height that is less than a second sheet height between the second top side and the second bottom side, and
• the second top side is foldable along a second top fold line extending a second length of the second rollable rectangular layer, the second bottom side is foldable along a second bottom fold line extending the second length, a second distance between the second top fold line and the second bottom fold line being substantially equal to the second tightener height, and
• a second top fastener and a second bottom fastener, the second top fastener positioned above the second top fold line, the second bottom fastener positioned above the second bottom fold line;
• a middle covering comprising a middle rectangular sheet comprising:
• a left side of the middle covering coupleable to the first medial side via a middle left-sided fastener;
• a right side of the middle covering coupleable to the second medial side via a middle right-sided fastener;
• a middle top side;
• a middle bottom side;
• a middle rollable rectangular layer coupled between the left side, right side, top side, and bottom side, wherein:
• the middle rollable rectangular layer, the first side covering and the second side covering are configured to be used in conjunction with one another to covering an opening in an attached rack, and
• the top side of the middle covering is foldable along a top fold line extending a length of the middle rollable rectangular layer, the middle bottom side is foldable along a bottom fold line extending the second length, a distance between the top fold line and the bottom fold line being substantially equal to the first and second tightener height;
• and
• a top fastener and a bottom fastener, the top fastener positioned above the top fold line, the bottom fastener positioned above the bottom fold line, wherein the top and bottom fasteners of the middle covering can move sideways such that the top and bottom fasteners of the middle covering can attach the top and bottom fasteners of either the first or second side covering, in doing so would allow a hole, which allows the installation of a non-standard size equipment.
