The rack is foldable from a first extended position to a second supporting position, forming two portions with triangular cross sections.
Claims12
A foldable support rack, comprising:
- a body member, generally flat, having first and second opposed major faces, and having a peripheral edge;
- the peripheral edge comprising:
- first and second opposed side edges, and first and second opposed end edges;
- wherein the body member has a first plurality of holes for receiving and engaging a plurality of securing tabs that are disposed along the first and second opposed end edges, and are equal in number to the first plurality of holes;
- and the body member has four transverse hinge portions, spaced to allow folding of the body member from a first extended position to a second supporting position,
- the second supporting position comprising two supporting portions, each having a triangular cross section, on a substantially flat base, and
- the body member has a second plurality of holes such that when the body member is folded into the second supporting position the second plurality of holes comprise at least two article receiving holes for supporting an article, and are disposed on the supporting portions, such that an article can be supported by engaging at least one of the at least two article receiving holes on one or both of the supporting portions.
