DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

This invention is designed to provide improved drainage from the top (animal) supporting surface of a floor used within an animal shelter, such as a shelter for a herd of animals. In addition, it is considered the edge portions of the slats or panels facilitate the breakage of straw or hay or other solid animal fodder such that that (waste) material laying on the top surface may be more readily or easily passed through a void into a chamber of collection facility beneath the flooring.

The slat and panel of this invention may be used with any animal shelter, although particularly preferred animal shelters are those as described by any one of

PCT/NZ2003/000195 (WO2004/022883), PCT/NZ2006/000324 (WO2007/069916), PCT/NZ2008/108669 (WO2008/108669), PCT/NZ2008/000121 (WO2008/147224), each of which are hereby incorporated by reference.

The following description shall now be made with reference to the accompanying drawings 1A-6.

Figure 1A shows a profile view of two slats 1 according to the invention and arranged side-by-side to form a central void space 7 through which waste material can pass to a collection chamber or facility (not shown) below the floor. Figure IB shows a perspective view of the slats 1 of figure 1, illustrating how a series of longitudinal slats 1 can be arranged in an array side-by-side to form the flooring for a shelter (not shown).

Figures 2-4 show a panel 10 according to the invention in which a series of central void spaces 7 are provided. The panel 10 including the convex or upwardly bulged profile 5 and shoulder portions 6 with their bevelled edges.

In a first embodiment, there is provided a flooring slat 1 for forming the floor of an animal shelter (not shown in-situ), the flooring formed at least by a series of two or more slats 1 aligned longitundally aside each other, the slat 1 comprising a top animal supportive surface 2 and a pair of opposed side walls 3 angularly disposed away from the top surface 2 and tapering towards each other to a bottom surface 4, the top surface 2 being of a substantially convex, or upwardly bulged, profile 5 including a pair of shoulder portions 6 adjacent the top surface 2 and side walls 3, the shoulder portions 6 being bevelled edges and sloping towards the respective side walls 3. In a second embodiment there is provided a flooring panel 10 for forming the floor of an animal shelter (not shown), the panel 10 including one or more of flooring slats 1, a flooring slat 1 comprising a top animal supportive surface 2 and a pair of opposed side walls 3 angularly disposed away from the top surface 2 and tapering towards each other to a bottom surface 4, the top surface 2 being of a substantially convex, or upwardly bulged, profile 5 including a pair of shoulder portions 6 adjacent the top surface 2 and side walls 3, the shoulder portions 6 being bevelled edges and sloping towards the respective side walls 3.

In a third embodiment there is provided a flooring panel 10 for forming the floor of an animal shelter (not shown), the panel 10 including one or more flooring slats 1 or edge portions thereof (for example the longitudinal edges of figure 2), each of the slats 1 defining a void space 7 about which is a top animal supportive surface 2 and a pair of opposed side walls 3 angularly disposed away from the top surface 2 and tapering towards each other to a bottom surface 4, the top surface 2 being of a substantially convex, or upwardly bulged, profile 5 including a pair of shoulder portions 6 adjacent the top surface 2 and side walls 3, the shoulder portions 6 being bevelled edges and sloping towards the respective side walls 3.

It should be appreciated two or more flooring panels 10 can be aligned beside each other such that alignment of the panels allows formation of floor, portions of respective edges of the panels 10 forming further slats 1 or parts of a panel 10. Such respective edges are labelled as 12 in figure 2.

In various embodiments of the invention, particularly preferred dimensions of a panel 10 according to the invention can be a panel 10 of about 3510 mm in length or about 1200 mm in width or about 100 mm in depth. In one particular example, a panel 10 is provided having the following dimensions: about 3510 mm in length, about 1200 mm in width and about 100 mm in depth.

The slats 1 and panel 10 are advantageously formed of pre-stressed concrete. Most desirable is a high-density pre-stressed concrete, for example a slat 1 or panel 10 formed having a uniformly distributed live load of about 5 kPa (or about 2.1 tonnes evenly spread over the entire top surface). It will be appreciated other forms and types of materials may be utilised. However, high density pre-stressed concrete may provide the most economical of material forms.

As the slats 1 or panel 10 is designed for the formation of an entire or at least part of a floor of an animal shelter, it is useful for the slats 1 or panel 10 to be transportable or at least portable via mechanical devices, such as by a tractor or by lifting using the forks (tines) of a fork-lifter. Therefore, it is advantageous if the improved slat 1 or panel 10 includes at least one or a series of lift points, the lift points for lifting the slat or panel with the forks of a fork-lifter. Similarly, strengthened portions of the slats 1 or panel 10 may be provided for accepting of point loads. For example, point loads accepting of about 500 kg weight may be provided across the slat 1 or panel 10, point loads may further for example be distributed about 900 mm apart across the slat 1 or panel 10. It will be appreciated other lifting or transport methods may be employed, for example a series of lift eyelets may be incorporated as a feature of the slat 1 or panel 10 design.

As illustrated by figure 6, slats 1 or panels 10 can be arranged in a manner allowing them to be stacked one atop the other, or are at least stackable for reducing an overall volume of storage, for example for transport purposes.

The slats 1 or panel 10 of the invention are designed for forming the flooring of an animal shelter. In this respect, the slats 1 or panel 10 need to be configured or configurable for resting on the rim of a collection chamber located underneath the flooring. The slat 1 or panel 10 therefore can include a support or supports for supporting the slat 1 or panel 1- above a lower-most (collection) chamber or facility. For example, a chamber for collection of animal fodder (food) or animal waste can be a concrete bunker type facility having a recessed upper rim or edge or top edge surface upon which the slats 1 or panel 10 can rest or be located or are locatable. The support or supports from the slat 1 or panel 10 can be of the form of one or more legs extending from a perimeter or other portion of an edge 12 of the slat 1 or panel 10 or their bottom surface 4.

As shown particularly clearly by figure 1, the top surface 2 is raised above the shoulders 6 in an upwardly bulged or convex profile 5. In one example, the top surface 2 is raised about 5 mm above the shoulders 6, although other examples include the top surface 2 raised between about 2 mm to about 5 mm above the shoulders 6, or raised by less than about 50 mm above the shoulders 6. Alternatively, the top surface 2 can be raised about 50, 49, 48, 47, 46, 45, 44, 43, 42, 41, 40, 39, 38, 37, 36, 35, 34, 33, 32, 31,30, 29, 28, 27, 26, 25, 24, 23, 22, 21, 20, 19, 18, 17, 16, 15, 14, 13, 12, 11, 10, 9, 8, 7, 6, 5, 4, 3, 2, 1 mm above the shoulders 6.

Design of the profile of the top surface 2, being of a substantially convex, or upwardly bulged, profile assists in facilitating drainage of liquid animal waste towards the void 7. Further, the top surface 2 being of a substantially convex, or upwardly bulged, profile facilitates drainage of animal fodder (food) towards the void 7. As also illustrated by the figures, the shoulders 6 have a bevelled edge. The bevelled edge may be a reduction in height from the top surface 2 by about 5 mm. In one example, the bevelled edges are bevelled by between about 2 mm to about 5 mm below the top surface 2. Alternatively, the bevelled edges can be bevelled to be less than about 50, 49, 48, 47, 46, 45, 44, 43, 42, 41, 40, 39, 38, 37, 36, 35, 34, 33, 32, 31,30, 29, 28, 27, 26, 25, 24, 23, 22, 21, 20, 19, 18, 17, 16, 15, 14, 13, 12, 11, 10, 9, 8, 7, 6, 5, 4, 3, 2, 1 mm below the top surface 2.

In forming a floor from multiple slats 1 or the panel 10, the shoulders 6 with bevelled edges of a first slat (or a first slat portion in a panel 10) are placed (or located) substantially parallel to the shoulders 6 with bevelled edges of a second slat (or a second slat portion in a panel 10), such that the slats 1 adjoining edges 12 facilitate breaking or breakage of solid animal waste or solid animal fodder (food). For example, hay or straw can be pushed by animal's hooves towards the void 7, the shoulders 6 with bevelled edges providing for a generally cutting surface of the straw or hay or other solid waste, for subsequent disposal away from the top surface and through the void 7. Importantly, the adjoining angles of the bevelled edges of the shoulders 6 do not impact on the hoof of an animal.

Alignment of two slats 1 side-by-side (as shown in figure 1) provides for a central void 7, or the panel 10 includes central voids 7 (as shown in figure 2). The central void is dimensioned for allowing animal fodder (food) or animal waste, or both, to pass from the top surface 2 through the void 7, which can then fall into the chamber or collection facility below the floor.

Located beneath the slat or panel is one or a series of collection or storage chambers for waste material passed from the top surface 2 through the void 7. Likewise, a series of passages or other chambers can be used to direct flow of waste material away from beneath the flooring and away from the animals.

As discussed above, two or more slats 1 can be aligned in a side-by-side arrangement (such as the arrangement of figure 1), their opposed side walls 3 of each slat 1 together forming a central void 7 between each of the shoulders 6.

It will be appreciated the one or more of the slats 1 or panels 10 form the flooring or part of the flooring of an animal shelter. Such animal shelters may be particularly those as described by any one of the following: PCT/NZ2003/000195 (WO2004/022883), PCT/NZ2006/000324 (WO2007/069916), PCT/NZ2008/108669 (WO2008/108669), PCT/NZ2008/000121 (WO2008/ 147224), each of which is hereby incorporated by reference.

The foregoing description of the invention includes preferred forms thereof. Modifications may be made thereto without departing from the scope of the invention.
