Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
109 words
A floor frame structure comprising two spaced side perimeter members of steel construction disposed in spaced parallel relationship to one another, forwardly and rearwardly disposed cross members of steel construction rigidly connected to said side members forming a rigid frame and being disposed in parallel relationship with one another, a plurality of hangers on the inner side of two of said members of parallel relationship for receiving the ends of additional members for supporting a floor on said frame structure, and wooden cross members seated between said side members principally below the upper surface thereof and having an exposed upper surface for supporting flooring and receiving flooring securing means.
Claim 2
Dependent Claim
109 words
A floor frame structure comprising two spaced side perimeter members of steel construction disposed in spaced parallel relationship to one another, forwardly and rearwardly disposed cross members of steel construction rigidly connected to said side members forming a rigid frame and being disposed in parallel relationship with one another, a plurality of hangers on the inner side of two of said members of parallel relationship for receiving the ends of additional members for supporting a floor on said frame structure, and wooden cross members seated between said side members principally below the upper surface thereof and having an exposed upper surface for supporting flooring and receiving flooring securing means.
Claim 3
Dependent Claim
42 words
A floor frame structure as defined in claim 1 in which said hangers on two of said members of parallel relationship are disposed along the inside surface of said side members for receiving the ends of cross members between said side members.
Claim 4
Dependent Claim
