Interfitting plastic panels

A cover adapted to fit over a container for liquids comprising:

• a plurality of interfitting panels of an extruded material having a generally rectangular shape having upper and lower surfaces and opposed edges extending between said surfaces, each of said panels having a plurality of parallel hollow compartments therein;
• interfitting male and female connectors on said opposed edges of said panels;
• means on said interfitting connectors to restrict relative articulated movement between adjacent interfitted panels;
• said female connector including an upper flange and a lower flange defining a groove therebetween to receive male side connector, said female connector having extensions between said inner and outer flanges;
• and
• interfitting hollow sockets on said male connector receiving said extensions when said male and female connectors are in interfitting relation.

A cover adapted to fit over a container for liquids comprising:

• a plurality of interfitting panels of an extruded material having a generally rectangular shape having upper and lower surfaces and sides extending between said surfaces, and having a plurality of parallel hollow compartments therein and a plurality of longitudinally extending parallel grooves in the upper surface of said panels;
• interfitting male and female members connecting said plurality of panels together in side by side relation to form a plurality of panel sections, wherein said female connector includes upper and lower flanges with a groove therebetween to receive the male connector, additional mutually interfitting extensions and hollow sockets located on said flanges and on said male connector;
• and
• a hinge extending between and pivotally connected to opposed sides of a pair of adjacent panel sections, said hinge permitting said pair of adjacent panel sections to be folded over each other to permit vertical stacking of said pair of panel sections in contacting horizontal layers;
• said hinge including a pivotally mounted link extending between male and female members of adjacent panel sections.

A generally horizontally extending cover adapted to fit over a container comprising:

• a plurality of interfitting panels of an extruded material having a generally rectangular vertical cross section and having upper and lower surfaces and opposed sides extending between said surfaces, having a plurality of parallel hollow compartments therein and a plurality of longitudinally extending grooves in the upper surface of said panel;
• one of said sides having a male connector and another of said sides having a female connector thereon;
• wherein said female connector includes upper and lower flanges with a groove therebetween to receive the male connector, additional mutually interfitting extensions and hollow sockets located on said flanges and on said male connector;
• and
• said male and female connectors of adjacent panels fitting together and capable of being removed from each other by relative vertical movement between said male and female connectors, whereby said adjacent panels may be disengaged for disassembly of said adjacent panels.

A cover adapted to fit over a container for liquids comprising:

• a plurality of connected panels of an extruded material having a generally rectangular shape having upper and lower surfaces and opposed edges extending between said surfaces, each of said panels having a plurality of parallel hollow compartments therein;
• interfitting male and female connectors on said opposed edges of said panels;
• means on said interfitting connectors to restrict relative articulated movement between adjacent interfitted panels;
• said female connector including an upper flange and a lower flange defining a groove therebetween to receive said male connector, said upper and lower flanges of said female connector having parallel inner planar surfaces in opposed relation to each other fitting against said male connector when in interfitting relation;
• said male connector having opposed outer planar surfaces in complementary relation to said inner planar surfaces of said female connector when in interfitting relation thereby to restrict articulated movement between said male and female connectors;
• said female connector having extensions between said inner and outer flanges, and interfitting hollow sockets on said male connector receiving said extensions when said male and female connectors are in interfitting relation thereby to restrict articulated movement between adjacent panels.

• said plurality of panels including a plurality of panels aligned in end to end relation;
• and
• a joint connector between each pair of panels aligned in end to end relation, said joint connector fitting within axially aligned hollow compartments of the aligned panels and connecting each pair of panels to each other in end to end relation.
