Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
234 words
A tile block comprising a body having a hexahedral right parallelepiped shape, said block having a first plurality of holes distributed uniformly along a first side of said body and horizontally extending in parallel from said first side of the body to an opposite second side of the body, a second plurality of holes distributed uniformly along a third side of said body which is perpendicular to said first and second sides, said second plurality of holes horizontally extending in parallel from said third side of the body to an opposite fourth side of the body, the first plurality of holes being extended in a direction transverse to the second plurality of holes and respective ones of the first plurality of holes intersecting and communicating with the second plurality of holes, each of said first and second holes having a predetermined transverse dimension and said body having a first surface bounded by and transverse to all of the aforementioned sides, and a plurality of recesses having a predetermined depth in said first surface of the body, the depth of said recesses being comparable to the transverse dimensions of said first and second holes, wherein said body includes a third plurality of holes vertically extending from said first surface to an opposite surface of the body, and said third plurality of holes being generally perpendicular to and intermediate said first and second plurality of holes.
Claim 2
Dependent Claim
