  • Figures 2 to 6 illustrate a representative one of the floor panels 22 composed of common features that are also embodied by all of the other floor panels, of which in the illustrated example, only the first end panel 22a differs from any of the other panels, specifically by having a pair of additional mounting flanges at opposing ends thereof to cooperate in the mounting of other chute components to the longitudinal frame members. It will be appreciated that in other embodiments, all of the floor panels may be identical, or there may a larger variety of floor panels that differ somewhat from one another, while retaining common inventive features among them.
  • the floor panel 22 features a main rectangular span 26 whose topside denotes a flooring area over which animals traverse during their passage through the chute.

  • the length dimension of the floor panel lies parallel to the transverse direction of the floor assembly, while the shorter width dimension W of the floor panel 22 lies in the longitudinal direction of the overall floor assembly 10.
  • the sizing and relative width and length of each floor panel 22 may vary from those of illustrated embodiment.
  • the length dimension L of the floor panel’s main span 26 exceeds an inner lateral dimension of the of the floor assembly measured transversely across an inner frame space thereof delimited between the inner sides of the two longitudinal frame members 12.
  • the length dimension L of the floor panel does not exceed an outer lateral dimension of the floor assembly measured transversely between the outer sides of the two longitudinal frame members.
  • the two opposing ends of the floor panel’s main span 26 rest atop the longitudinal frame members 12 when the floor panel is placed and fastened in an installed position spanning therebetween.
  • the main span 26 features a set of mounting holes 32 therein by which the floor panel is fastenable to the topside of the respective longitudinal frame member, for example by rivets or other fasteners, to secure the floor panel in its installed position.
  • each longitudinal frame member includes a set of mounting apertures in the topside 12a thereof at spaced locations along the longitudinal direction of the flooring assembly, and each of these mounting apertures 36 aligns with a respective one of the mounting holes 32 in the floor panels.
  • Each floor panel is fastened to the longitudinal frame members 12 by rivets 38 that are fastened through the aligned mounting holes and apertures at the ends of the floor panel.
  • the riveted installation of the floor panels is preferable over welded attachment, as it provides semi-permanent yet removal attachment of the floor panels to the frame.
  • the rivets can be removed, for example by shearing off the heads of the rivets and punching or drilling out the pins of the rivets, and new floor panels then installed by riveting in a replacement set of panels. No specialized welding skills or equipment are required.
  • the panel 22 of the illustrated embodiment features a pair of respective downturned flanges 34 that hang perpendicularly downward from the main span 26 over a near entirety of the length dimension L thereof.
  • Each downturned flange 34 stops slightly short of the two opposing ends 28a, 28b of the main span 26, whereby the two downturned flanges 34 spans less than the full inner lateral dimension of the floor assembly, and thus fit between the two longitudinal frame members 12 in the floor panel’s installed position.
  • the main span 26 and downturned flanges 34 are seamlessly integral parts of a singular unitary sheet of metal, bent at ninety degrees at the opposing lengthwise edges 30a, 30b of the rectangular main span 26 to create the perpendicularly downturned flanges 34.
  • the downturned flanges 34 serve multiple purposes.
  • the hanging position of the flanges 34 between the longitudinal frame member 12 of the floor assembly block the floor panel from shifting in the transverse direction of the floor assembly should the fastened mounting of the floor panel fail. Additionally, they impart rigidity and strength to the floor panel, eliminating the need for separate underlying cross members in the floor assembly to prevent deflection of the planks under the weight of traversing animals.
  • the main span 26 of the panel 22 features a plurality of apertures 36 opening therethrough in an arrayed pattern distributed over the surface area thereof.
  • Each aperture penetrates through the full thickness of the main span 26 from the topside thereof over which animals traverse, to the opposing underside thereof that faces downwardly toward the underlying ground surface atop which the floor assembly 10 resides.
  • Each aperture 36 is surrounded by a respective non-planar rim 38 spanning a full 360-degrees around the aperture 36.
  • the rims 38 all bulge upwardly from surrounding planar regions 39 of the panel’s topside, over which the rimmed apertures are uniformly arrayed to protrude upwardly from a shared reference plane occupied by all of the planar regions.
  • an entire remainder of the panel’s topside consists of said planar regions and thus resides entirely in said shared reference plane. Accordingly, the end-adjacent areas of the panel’s main span through which the mounting holes 32 penetrate define integral mounting portions of the panel residing in coplanar relation to the planar regions 39 of the panel’s topside.
  • a penetrating aperture 36 and surrounding non-planar rim 38 of elevated relation to the surrounding planar regions of the floor panel 22 is believed to provide greater tractional benefit to the animals traversing the chute, compared to the more conventional aperture-free embossments of diamond plate, as both the raised outer perimeter of the non-planar rim 38 and the boundary of the aperture 36 delimited at the inner perimeter of the non-planar rim 38 create frictional edges for the animal’s footing to achieve traction relative to the smooth surface of the surrounding planar regions 39, whereas the embossments of diamond plating provide frictional edges only at the outer perimeter thereof.
  • the apertures penetrating through the floor panel enable passage of moisture and muck downwardly therethrough.
  • the floor panels 22a - 22i are installed at spaced apart positions in the longitudinal direction of the frame to leave open gap spaces G between the adjacent floor panels as best shown in Figure 7.
  • the topside of the main span 26 features a raised rib 40 that also resides in upwardly protruding relation to the planar regions 39 of the panel, and reaches a greater elevation than that reached by the non-planar rims 38 of the apertures.
  • the rib 40 spans lengthwise of the floor panel, preferably over the full length thereof from one end 28a, 28b of the panel to the other.
  • the rib 40 lacks any of the rimmed apertures thereon, and divides the rimmed apertures 36 into distinct sets of apertures on opposite sides of the rib 40.
  • the illustrated embodiment features only a singular, generally central rib 40 and two sets of rimmed apertures disposed on respective halves of the panel, but it will be appreciated that the number of ribs and aperture sets may be increased.
  • the ribs of the floor panels serve to create additional tractional elements lying cross-wise to the longitudinal travel direction of the chute, thereby supplementing the rimmed apertures, but without the installation of separate bars of the type referenced in the background above.
  • each aperture set features three rows of rimmed apertures 36, each row running lengthwise of the floor panel.
  • Each row has equal inter-aperture spacing to the other rows, but with the middle row offset relative to the two other rows by half of this inter-aperture distance such that each aperture in the middle row is situated half way between two adjacent apertures in each of the other two rows.
  • the rib 40 of the illustrated embodiment is triangular in cross-section, thus corning to a peak or apex 40a at its uppermost elevation, through other shapes may be employed, for example including semi-circular or other arcuately curved shapes, or rectangular shapes, square or otherwise.
  • the rib is an integrally formed component of the same metal sheet that forms the rest of the floor panel, having been formed therein with suitable bending equipment.
  • the non-planar rims 38 of raised elevation at the topside of the floor panel are integrally formed components of the same singular metal sheet forming the main span 26, downturned flanges 34 and lengthwise rib 40. This is best shown in the cross-sectional view of Figure 6, where it can be seen that the bottom surface of each non-planar rim 38 angles upwardly in elevated relation from surrounding planar regions of the panel’s underside, just as the top surface of each non-planar rim angles upwardly in elevated relation from the surrounding planar regions of the panel’s topside.
  • the rimmed apertures of this type may be formed, in one example, by pre-drilling each aperture into the sheet, and then forcing a male dimple die into the sheet from the underside thereof to bulge the annular area around the pre-drilled aperture outwardly at the opposing topside of the sheet.
  • the aperture and respective rim may be simultaneously formed in a single operation using a punch and flare tool whose male flare die is likewise pressed into the sheet from the underside thereof to create the bulged rim at the topside of the sheet, while the aperture is simultaneously punched through the sheet.
  • topside and underside are used in relation to the installed position of the finished floor panel in the final floor assembly, and not to a particular orientation in which the metal sheet resides during the actual manufacturing process. Accordingly, if a first face of the metal sheet refers to the side thereof that forms the topside of the installed floor panel, and an opposing second face thus forms the opposing underside of the installed floor panel, then the male tools are forced into shape-forming engagement with the second face of the metal sheet to bulge the sheet outwardly at the opposing first face thereof, thereby creating the non-planar rim 38 at the topside of the floor panel.
  • the elevation of the aperture-surrounding rims 38 from the planar regions of the floor panel preferably doesn’t exceed a maximum if 8mm, and for example may be in the range of 2-7mm, more preferably between 4-6mm, and optimally 5-6mm, to prevent risk of potential injury to the animals if protruded to greater heights.
  • the formation of the bulged rims in the sheet may also imparts extra rigidity thereto to improve the durability of the floor panel.
  • the illustrated embodiment reflects an embodiment produced by forced application of male dimple or flare tools from the underside of a metal sheet to create the bulged aperture rim at the opposing topside
  • floor panels of similar physical structure produced by different manufacturing methods using different materials are also within the scope of the present invention.
  • a variety of different metals may be used, including stainless steel embodiments for corrosion resistance, or use of other metals optionally coated with an anti-corrosive finish to achieve such corrosion resistance.
  • the illustrated embodiment is shown in the context of a squeeze chute floor assembly, the same floor planks may be used in a variety of livestock equipment to form an animal traversable floor surface thereof.
  • livestock loading ramps is one such example of an alternative application.
