Abstract
Abstract A floor for use in animal husbandry is provided consisting of a number of elongated extruded aluminum floor lengths each of which has a slotted top surface with longitudinally and transversely spaced apart slots, each length having a multiplicity of integral vertical support beams extending from the undersurface of the slotted surface and terminating in footed ends, one longitudinally extending side of the slotted surface having an arcuate male connector configuration and the other longitudinally extending side having a correspondingly dimensioned female connector configuration whereby adjacent lengths are pivotably connectable to one another.

Claim 1
Independent Claim
234 words
A flooring structure for use in animal husbandry comprising: a floor assembly constructed of a plurality of individual lengths of extruded material, each of said lengths having a flooring surface with transverse side margins, a top surface and an undersurface, at least three support beams extending normal to said undersurface from said undersurface, said support beams extending longitudinally of the length of said lengths, said support beams terminating in increased dimension footed ends, a plurality of longitudinally spaced apart slots through said flooring surface intermediate adjacent support beams, longitudinally continuous raised stiffening ribs extending the length of said lengths projecting from the undersurface adjacent the slots on either side thereof, one of said side margins having an arcuate male connection configuration portion projecting therefrom, the male portion defining an open top longitudinally extending groove, the other of said side margins having an arcuate female connection portion extending thereinto, the male portion of one length receivable in the female portion of an adjacent length, and said adjacent lengths being transversely coupled together by the indexing of said connecting portions, an additional row of longitudinally spaced apart slots provided at the side edge having the male coupling member with the slots of said additional row of slots formed partially through portions of said male portion projection, including portions of a bottom of the groove, and at least partially formed through adjacent portions of the flooring surface.
