Abstract
Abstract A slotted floor section for supporting animals, as hogs and cattle. The floor section has a plurality of longitudinal members having plywood cores located in side-by-side laterally spaced positions. A plurality of transverse members are located adjacent the bottom of the longitudinal members. The longitudinal and transverse members are covered with a plastic reinforced with fibers. The transverse members have a plurality of lugs which laterally space the longitudinal members. Connecting structures attach the transverse members to the longitudinal members. A granular material embedded in the top portion of the plastic material provides the top surface of the longitudinal members with a rough texture to enhance animal footing.

Total Claims: 19
Claim 1
Independent Claim
228 words
A slotted panel floor assembly for covering a support surface comprising: a plurality of longitudinal members, each longitudinal member having a longitudinal core and plastic means reinforced with fibers covering the entire core, said longitudinal member having an upper surface, a bottom, and downwardly and inwardly converging longitudinal sides; a plurality of longitudinally spaced transverse members extended transversely across the bottom of the longitudinal members, each transverse member having a transverse core, plastic means reinforced with fibers covering the entire transverse core, each transverse member having a top, a bottom engageable with said surface to support the panel assembly on said surface, upwardly and inwardly converging sides upwardly directed first projections, spaced along the top of the transverse member and an end second projection extended laterally away from an outside longitudinal member to space the panel assembly from an adjacent panel assembly, each first projection having upwardly converging sides engageable with the convering sides of adjacent longitudinal member to laterally space the adjacent longitudinal members from each other and locate the longitudinal members in side-by-side longitudinal positions relative to each other, said upwardly converging sides of each first projection being generally continuous with the downwardly and inwardly converging sides of the longitudinal members; and means connecting the transverse members to the longitudinal members and holding the longitudinal members between adjacent first projections on each of the transverse members.
Claim 2
Dependent Claim
