Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
118 words
A base member comprising a top and bottom panel, a reinforcement extending between and spacing said top and bottom panels, said reinforcement having a pair of beam members positioned one at each side of said base and a reinforcing filler in the space between said beam members, said reinforcing filler being formed by an expanded honeycomb material oriented so that the longitudinal axes of apertures formed through the expanded honeycomb extend substantially perpendicular to said top and bottom panels, said beams being formed of honeycomb material oriented in the same manner as said expanded honeycomb forming said filler, said honeycomb material of said beams being expanded to a lesser degree than said expanded honeycomb material of said filler.
Claim 2
Dependent Claim
