Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
100 words
A floor system having a first floor means including a pair of projection means extending outwardly and downwardly from the bottom surface of said first floor means and beyond the top surface of said first floor means; a second floor means carried on said projection means of said first floor means in a free floating engagement, said second floor means having sidewall portions extending downwardly from a top surface of said second floor means whereby said sidewalls are positioned outboard of said projection means and the bottom surface of said second floor means is in contact with said projection means.
Claim 2
Dependent Claim
100 words
A floor system having a first floor means including a pair of projection means extending outwardly and downwardly from the bottom surface of said first floor means and beyond the top surface of said first floor means; a second floor means carried on said projection means of said first floor means in a free floating engagement, said second floor means having sidewall portions extending downwardly from a top surface of said second floor means whereby said sidewalls are positioned outboard of said projection means and the bottom surface of said second floor means is in contact with said projection means.
Claim 3
Dependent Claim
