Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
143 words
Floor structure comprising: a base plate having a plurality of apertures; each of said base plate apertures including at least one keyway; a floor tile having an interlocking element; a plurality of load bearing stand-offs for insertion through said base plate apertures, said stand-offs being removably secured to said base plate to support said floor tile in spaced relation to said base plate; said stand-offs forming a plurality of channels beneath said floor tile; said stand-offs including means for removably engaging said floor tile locking element for removably interlocking said base plate to said floor tile; and each of said stand-offs having a base portion including at least one radially located locking tab formed to pass through said base plate aperture keyways such that upon insertion of said stand-offs through said base plate apertures said stand-offs are removably secured to said base plate.
Claim 2
Dependent Claim
143 words
Floor structure comprising: a base plate having a plurality of apertures; each of said base plate apertures including at least one keyway; a floor tile having an interlocking element; a plurality of load bearing stand-offs for insertion through said base plate apertures, said stand-offs being removably secured to said base plate to support said floor tile in spaced relation to said base plate; said stand-offs forming a plurality of channels beneath said floor tile; said stand-offs including means for removably engaging said floor tile locking element for removably interlocking said base plate to said floor tile; and each of said stand-offs having a base portion including at least one radially located locking tab formed to pass through said base plate aperture keyways such that upon insertion of said stand-offs through said base plate apertures said stand-offs are removably secured to said base plate.
