Abstract
A protective arrangement comprising one or several plane structures such as protective plates or elements, each one of which is meant to be used with one or several similar ones and are removably attached to one another. The structural part is stiffened in proportion to bending and has stiffening ribs. The arrangement is meant for temporarily protecting a field of grass and/or ice. One or several plastic based thermal insulation assemblies are attached to the downward side of the supporting structural part. A supporting structure is formed from the thermal insulation assembly that projects from the downward surface of the stiffening ribs.
Claims27
A surface covering protective structure, comprising:
- at least one stiff structured plane structure operable to cover a protected surface, each plane structure comprising:
- at least one stiffened supporting part comprising plastic-based material, the stiffened support part comprising a plurality of stiffening ribs, and
- at least one thermal insulation supporting part removably connected to at least a portion of a downward side of the stiffened supporting part, wherein the thermal insulation supporting part is removably fastenable to the stiffened supporting part, wherein the thermal insulation part extends to a lower level than the stiffening ribs to engage the protected surface, and wherein the thermal insulation supporting part is supported between at least two successive stiffening ribs.
A surface covering protective structure, comprising:
- a plurality of stiff structured plane structure operable to cover a protected surface, each plane structure comprising:
- at least one stiffened supporting part comprising a plurality of stiffening ribs, and
- at least one thermal insulation supporting part removably connected to at least a portion of a downward side of the stiffened supporting part, wherein the thermal insulation part extends to a lower level than the stiffening ribs to engage the protected surface;
- a connecting structure operable to removably attach adjacent plane structures to each other;
- and
- a fitting joint operable to couple adjacent thermal insulation supporting parts to each other.
A surface covering protective structure, comprising:
- at least one stiff structured plane structure operable to cover a protected surface, each plane structure comprising:
- at least one stiffened supporting part comprising a plurality of stiffening ribs, and
- at least one thermal insulation supporting part removably connected to at least a portion of a downward side of the stiffened supporting part, wherein the thermal insulation part extends to a lower level than the stiffening ribs to engage the protected surface;
- and
- a grip assembly arranged at lower edges of the stiffening ribs, wherein the grip assembly is operable to engage and retain the thermal insulation supporting part.
