a top surface plate and said top surface plate
affixed to said mats' top by attachment means; and
bottom surface plate and said bottom
surface plate affixed to said mats' bottom by
attachment means.
two adjoining edges about the perimeter of
said mats being recessed from the bottom of said
mats to form adjoining upper lips and lower risers
along one side and one end of said mats;
wherein the remaining two adjoining edges
about the perimeter of said mats being recessed
from top of said mats to form adjoining lower lips
and upper risers along the opposite side and
opposite end of said mats;
wherein the depth to which said mat edges
are recessed to form said lips about the entire
perimeter of said mats being substantially the same
such that two diagonally opposite corners of said
mat are removed in the areas where said upper lips
would otherwise intersect with said lower lips, thus
allowing for the overlapping of said upper and
lower lips about the edges of said mat with
respective lower and upper lips of other like mats
when placed adjacent thereto for joining therewith
by which said overlapping mats have a generally
flat continuous top and bottom surface;
said upper lips slope downward from edge
of said mat to lower risers and said lower lips slope
upward from edge of said mat to upper risers;
said overlapping mats' lips are secured
together by a composite integral fit joint, a snap
fit joint or an integral design feature joint in
which the joint is held together by material
interference with the contacting surfaces of the
overlapping lips to produce a flush surface
