Description
APPARATUS FOR USE WlTH A SLATTED FLOOR
The invention relates to apparatus for use with a slatted floor and to a floor covering for
placement on the individual slats of a slatted floor in an animal house for housing animals,
such as but not exclusively bovines, pigs, sheep, deer and other animals which may be
housed in buildings having slatted floors or kept on slatted floors located externally. The
floor covering will be referred to in brief as a slat mat. The apparatus can be used with
slats made from any material, for example concrete, metal, plastic or wood.
The invention relates to an improvement in the invention disclosed in International Patent
Application No. PCT/EP O2/00274 dated January 4”‘ 2002 (Publication No. WOO2/065831
A2) the contents of which are incorporated herein by reference. The floor covering of that
apparatus comprises an elastomeric mat which is designed for cleanliness and enhanced
protection and comfort for animals and includes an openable flap along both or one of the
longitudinal edges of the mat to minimise the gap between adjacent slats of a slatted floor
so as to reduce the emission of gases and fumes emanating from a waste collection tank
beneath the floor while allowing waste matter to pass through the slatted floor to the tank.
The above mat is securable to an individual slat by screws which are securable in rigid
strip(s) located at the base of the mat. While this method of securing a slat mat is very
effective and strong, it is an object of the present invention to improve the method of
installation.
Slatted floors are generally mounted over slurry collection tanks or floors that lead to
slurry collection tanks which can hold slurry for prolonged periods of time. Therefore this
leads to a major problem with the emission from the tanks of dangerous gases which
would be injurious to the environment, and unpleasant odours from such tanks. This
problem can give rise to difficulties for persons working in these areas and living adjacent
to these areas and not to mention the animals themselves. In recent times pollution
control authorities have begun to issue strict controls on these areas and to limit the
number of animals which may be housed there. This obviously has large cost implications
for the owners of such enclosures with regard to the numbers of livestock that can be
housed.
A further object of the invention is to attempt to alleviate the problem of the emission of
such gases and fumes and to reduce the upward air-drafts that the animals may be
subjected to.
The present invention provides a floor covering apparatus for an animal house or location
adapted to provide comfort and protection for animals, comprising an elongated
elastomeric mat adapted to be fitted to a floor slat, the mat having a leg at each
longitudinal side of the mat, each leg being adapted to extend into the gap between
adjacent slats, the two legs of each mat serving to locate the mat.
Preferably, one or each leg of the mat is provided with gripping means to facilitate the
gripping of the mat to the slat.
Even if the floor covering apparatus for fitting to a slatted floor does not have a cushion
effect as outlined in the above specification, the fact that the rigid floor covering apparatus
could contain any or all of the following features, means it could be considered as having
‘comfort features‘:
- a curved surface to promote the movement of animal urine and faeces to the slurry
collection tank below and to reduce the retention of such waste materials on the mat
surface.
o a surface to reduce urine absorption into the slats, in particular concrete slats, and
hence reduce slat degradation.
- surface treatments that could include textured embossing or the addition of a further
non-slip grip surface made from a material applied either in the form of a complete
skin or in the form of beads or other similar textured features. The inclusion of such
surface treatments would ideally contribute to improved durability and would also allow
the application of biocide treatments for the added protection of the animals.
o a mat sized to match the profile of the slats and having a surface to promote the
transfer of the animal waste to the tank below, thereby improving the animal
cleanliness and reducing the amount of materials that may cause gaseous emissions
such as ammonia that would otherwise be retained on the slat.
o plastics construction which would reduce damage to the slats and hence significantly
reduce injuries caused to the animals.
o the inclusion of a flap valve means to reduce gas emissions and unpleasant odours
would also add to the animal welfare.
Conveniently, one or each leg of the floor covering apparatus has one or more elbows
along its length to facilitate the gripping of the mat to the slat.
Advantageously, the floor covering apparatus is ideally suited to manufacture by co-
extrusion whereby the apparatus is produced as having a unitary construction.
Preferably, a flap valve is provided at one or both sides of the slat mat, the flap valve or
valves being adapted to protrude into the gap between adjacent slats. The flap valve(s)
may be provided with a movement joint, whereby pressure on the upper surface of the
mat by an animal standing or moving thereon ideally allows the flap valve to flex and
move in the gap between the slats to permit animal waste to fall into a waste collection
tank located underneath the slatted floor.
The term “flap va|ve" when used in this specification is not to be read merely to describe
the device shown in the drawings but is meant to cover any device, mechanism or means
which can restrict the gap between adjacent slats but still allows waste material to pass
through the gap and can be manufactured from any material.
Alternatively, a flap valve is provided at one or both sides of the slat mat, the valve being
adapted to protrude into the gap between adjacent slats at a level below the floor. As the
flap valve rests below the floor surface, it is less likely to be damaged by the hooves or
bodies of animals as they move about on the floor.
In one arrangement, the elastomeric mat is supported by a bed of rigid material, the bed
comprising the legs and each leg being resiliently deformably biased to engage a slat. In
another arrangement, the legs are formed integrally with the elastomeric mat.
The mat may conveniently be provided with formations located on one or more of its
surfaces which, is use, are in contact with a slat. Said formations are adapted to resist
slippage of the mat relative to the slat. Any anti—slip means are suitable for this purpose.
Conveniently, each leg is 10mm or longer.
When a flap valve is provided at each side of the mat, the respective flap valves reduce
the gap in the opening between adjacent slats by coming into proximity with each other.
These flaps may be of a single or multiple flap design or of a ‘bubble’ valve of a singular or
multiple chamber type. They may be supplied as integral part of the mat or they may be
provided as a separate component to be fixed to the vertical fixing legs on a locator
provided on the mat, thereby allowing for the replacement of these flaps, without having to
necessitate the replacement of the complete mat.
The invention also provides a floor covering apparatus ideally having a low-profile domed
upper mat portion fixed to a bed of a material, ideally plastics, such that any waste matter
deposited onto the a floor covering apparatus will tend to move towards the flap valve
provided at one or both sides.
The present invention also provides an apparatus adapted to be fitted to the underside of
a mat or slat, the apparatus comprising an elongate member and having a flap valve
extending laterally outwardly from at least one longitudinal edge.
The present invention further provides a flap valve for fitting to a slat, the valve formed
from resilient and ideally high-slip or low friction material so that it may return after waste
materials have passed through adjacent floor slats so that the emission of gases and
odours from a collection tank below is reduced by the valve arrangement fitted to the floor.
The present invention also provides a slat provided with elongate grooves or channels
which may either be pre-formed into or cut into the slat and adapted to receive
complementary shaped anchoring formations provided on corresponding mats or flap
valves.
The flap valve design is novel in that it is designed to be replaceable, so that it can be
retro-fitted as required without the need to change the complete floor covering which is
provided with a rigid fixing means incorporated in the main profile or co-extruded with the
main profile.
The flap valve may also be designed so that it comprises a special high slip surface to
promote the transfer of the animal waste to a slurry collection tank below. Furthermore,
the flap valve is made from a special elastomeric which ideally allows the valve to recover
when the waste has passed through, thereby reducing the gas emissions and odours from
the slurry collection tank.
The present invention provides a longitudinal elastomeric flap valve to be provided for
inclusion in the main body on one or both sides of a slat, which may be made from
concrete, metal, plastic or wood, the flap valve protruding into the gap between the
adjacent slats. The flap valve may also be provided with a movement joint, whereby
pressure on the flap by animal waste allows the flap valve to flex and move in the gap
between the slats to permit the animal waste to fall into the collection tank located
underneath the slatted floor and allows the flap valve to recover, thereby reducing the
emission of hazardous gases and odours emanating from the tank.
The invention provides a floor covering apparatus for an animal house adopted to provide
comfort and protection for animals, comprising an elongated profile adapted to be fitted to
a floor slat, the profile having a leg on one or each longitudinal side of the profile, the or
each leg being adapted to extend into the gap between adjacent slats, the or each leg
serving to prevent lateral movement of the profile.
Preferably, a flap valve is provided at one or both sides of the slat mat, the flap valve or
valves being adapted to protrude into the gap between adjacent slats. The flap valve(s)
may be provided with a movement joint, whereby pressure on the upper surface by the
animal waste, allows the flap valve to flex and move vertically in the gap between the slats
to permit the animal waste to fall into a waste collection tank located underneath the
slatted floor and then to recover to a horizontal or closed position, to reduce the gaseous
emissions and odours emanating from the waste collection tank.
The invention will hereinafter be more particularly described with reference to the
accompanying drawings which show, by way of example only, a number of embodiments
and modified embodiments of an apparatus according to the invention. In the drawings:

Referring to the drawings and initially to Figures 1 and 1a, the first embodiment of floor
covering apparatus comprises a mat 10 of elastomeric material ideally having an outer
skin 115 and a flexible core 11 which are fixed to a rigid fixing base which comprises a
bed 111 of a plastics material which has sufficient rigidity to support the flexible core 11
and the outer skin 115. The flexible core 11 may comprise a series of chambers or
cavities similar to the construction described in detail in the above-mentioned PCT
application. Each mat 10 has a leg 13 at each side and a separate flap valve or valves
12. The legs 13 sit down by the side of the slats A and B into gaps C formed between the
two slats. Each of the legs 13 can be formed in the shape shown in Figure 1a with a
natural bias to grip the sides of the slats.
The second embodiment of mat 110 is also shown in Figures 1 and 2 and is similar in
most respects to the first embodiment 10. However the legs of the mat 110, only one of
which 113 is shown in the drawings, are different. The leg 113 is shaped or designed to
facilitate its conforming with the shape of the slat and has a grip 125 at the end 126 of the
leg 113, thereby enabling the leg to conform with the slat and grip it to help prevent the
mat 110 from lifting. A movement joint 114 is provided between the mat 110 and the flap
valve 12 so that pressure on the upper surface of the mat 110 by animals standing or
moving on the upper surface may allow the flap valve 12 to move.
Referring to Figure 3, a third embodiment of a floor covering apparatus comprises a mat
310 of elastomeric material having an outer skin 315 and an flexible core 11 which are
fixed to a rigid fixing base which comprises a bed 311 of a plastics material which has
sufficient rigidity to support the flexible core 11 and the outer skin 315 and has sufficient
resilient deformability to enable it to clip or grip against slat D. The flexible core 11 may
comprise a series of chambers or cavities. Bed 311 includes a pair of laterally depending
legs 313. The lower portions 313b of each of the pair of legs are biased mutually inwardly
to engage the walls of the slat D and to hold the mat 310 firmly in place on the slat. A flap
valve 312 is provided as an integral component of the mat, extending laterally outwardly
from each leg 313. Ideally, the flap valve 312 is provided on the upper portion 313a of the
leg and is positioned thereon at a point below the upper surface of the slat D. In this way,
the flap valve is sunk below the surface of the slatted floor, reducing the likelihood of the
valve being damaged by the animals.
Two mutually adjacent flap valves 312 of adjacent mats may overlap in the gap between
two adjacent slats or the flap valves may meet end to end.
A fourth embodiment of mat 410 is shown in Figures 4a, 4b and 4c. Mat 410 is similar in
many ways to mat 310, but differs from this mat in that it comprises of either a single flap
valve 412 or a ‘bubble’ flap valve 412a, either of which may be supplied as a separate
component and fixed to locators 415 situated on the fixing legs 413. This allows the flap to
be manufactured from an alternative suitable material different from the raw material used
for the mat 410 and it also allows for easy replacement of the flap valves, in the event of
damage and/or wear, without having to replace the complete mat.
Means may be provided for resisting the tendency of the mat to slip on the slatted floor.
As shown in Figures 3, 4 a, 4b, 4c,4d and 4e, such anti-slip means may comprise dimples
formed on the undersides of the mat and legs which engage the slat. Other anti-slip
formations will equally be useful and such formations may be provided with any of the
embodiments of mat description herein
Referring to Figures 4d and 4e, the legs 413 of mat of the fourth embodiment 410 are
shown fitted with detachable flap valves which are provided with a valve return
mechanism and are adapted to attach to locators 415 situated on fixing legs 413. In
Figure 4d, each valve 416 comprises a pair of rigid flap members 417a, 417b which are
divergent from flexible joint 418 which provides a valve return mechanism that enables
valve 416 to pivot thereby allowing the passage of waste material through the gap in
adjacent slats. A compressible foam material 419 provided in the gap defined by divergent
flap members 417a, 417b provides a further valve return mechanism which operates
when a slat having a profile that interferes with the pivoting action of the valve about
flexible joint 418 is used.
In Figure 4e each valve 416 is shown having an alternative pivoting and valve return
mechanism. In this arrangement, rigid flap members 417a, 417b are divergent from
flexible hinge 420 which enables valve 416 to pivot thereby allowing the passage of waste
material through the gap in adjacent slats. A spring means 421, which is provided with
suitable means of attachment at its respective ends, extends between the undersides of
rigid flaps 417a and 417b, respectively. The spring means 421 provides a further valve
return mechanism which functions when a slat having a profile that interferes with the
pivoting action of the valve about flexible joint 418 is used so that a displaced flap is
returned to its normal closed position once the passage of waste material through the gap
between adjacent slats is complete. Dashed lines shown in Figures 4d and 4e indicate
schematically some exemplary alternative slat profiles.
A fifth embodiment of a floor covering apparatus particularly suited, but not exclusively, to
pigs is indicated generally by reference number 510, is shown in Figures 5a and 5b. Floor
covering apparatus 510 comprises a domed elastomeric, deformable upper mat portion
515 fixed to a bed 511 of a plastics material which has sufficient rigidity to support the
domed elastomeric upper mat portion 515 and sufficient resilient deformability to enable it
to grip against a slat. Upper mat portion 515 is of a lower profile than the respective
elastomeric, deformable mat portions of the previous embodiments and comprises a
domed upper surface that curves downwardly towards the mat edges such that any urine
and other animal waste matter deposited onto the floor covering apparatus 510 would
tend move towards the gap between adjacent slats. Provision of such a curved upper
surface may further serve to promote the movement of animal waste from the mat thereby
increasing the comfort of the animals thereon and also helps preserve the slat itself by
reducing absorption of urine into the concrete below.
Bed 511 includes a pair of laterally depending legs 513 formed in a shape having a
natural bias to grip the sides of a slat. Each mat also comprises a further pair of
downwardly extending ancillary legs 514 that are arranged at an acute angle with legs 513
such that they form a secondary flap.
in Figure 5a, elastomeric flap valves 512 which are provided as an integral component to
mat 511, extend laterally outwardly from the end of each leg 513. Two mutually adjacent
flap valves 512 ideally extend to reduce the gap between two adjacent slats as shown in
Figures 5a and 5b or alternatively, may meet in an overlapping manner.
In Figure 5b an alternative variant of the fifth embodiment of a floor covering apparatus
is shown wherein rigid fixing means 516, adapted to receive a separately
demountable flap valve 512, are incorporated, either by separate attachment or by co-
extrusion, onto the distal ends of the laterally depending legs 513. Separately
demountable flap valves 512 comprise an elastomeric flap element 512a and a base
element 512b such that a flap valve 512 can be attached to depending legs 513 of the mat
bed 511 with the lower edge of base element 512b fastened to fixing means 516 and the
upper edge of base element 512b wedged into the space formed between the distal end
of the legs 513 and the ancillary legs 514.
Referring to Figure 5c, an alternative means of attaching a floor covering apparatus of the
invention to a slat is shown. In the figure the floor covering apparatus is similar in most
respects to the fifth embodiment 510 of Figures 5a and 5b. However the bed 511 is
provided with an additional pair of spaced apart laterally depending legs 517 which are
adapted to engage with elongate receiving channels 521 that are defined by member 520
which is provided integrally with slat E. Laterally depending legs 517 are provided with a
plurality of angled ribs 518 so that said legs may be pressed into receiving channels 521
with an ensuing mechanical interlocking effect which helps prevent the floor covering
apparatus from lifting from the slat while in use. in the Figure the floor coverings are
shown having two mutually adjacent exemplary flap valves 512 extending from depending
legs 513 minimize or reduce the gap between the valves.
in Figure 5d the means of attaching a floor covering apparatus of the invention to a slat is
substantially the same as that of Figure 5c. However, the floor covering apparatus is
segmented into two spaced apart portions, each portion having a sloping deformable
upper mat portion 515a and a fixed bed 511a which is provided with a first laterally
depending leg 513a formed in a shape having a natural bias to grip the sides of a slat and
a second depending leg 517 which engages with a receiving channel 521 of member 520.
In this arrangement each spaced apart portion is fastened independently to an opposing
side of a slat with the raised upper surface 522 of member 520 occupying the gap
between said portions.
In Figure 5e, a the segmented floor covering apparatus of Figure 5d is shown fastened
directly to a slat that is pre-formed having elongate receiving channels 531 and a raised
central upper surface 532 such that the floor covering may be fastened directly to a slat
without the requirement of an integrated member 520 and with raised central upper
surface 532 occupying the gap between said portions.
A further embodiment of the invention comprising a separately demountable flap valve
assembly 600 that is adapted to be fitted to the underside of a slat is shown in Figures 6a,
6b and 6c. In Figure 6a, flap valve assembly 600 comprises an elongate bed 611 of
material adapted to be fitted to the underside of a slat D by screws or other suitable
means and having elastomeric flap valves 612 extending laterally outwardly from its
opposing longitudinal edges. Two mutually adjacent flap valves 612 meet end to minimize
or reduce the gap between two adjacent slats as shown in Figure 6 or alternatively, may
meet in an overlapping manner. In Figure 6a a version 600a of flap valve assembly is also
shown having only a single flap valve 612.
in Figure 6b, an alternative arrangement 600b of a flap valve assembly 600 is shown
having a bed 611b which is provided with downwardly dependent edges 613 from which
elastomeric flap valves 612b extend initially inwardly at their respective proximal ends
before curving divergently outwardly.
In Figure 6c, a further arrangement 600c of the flap valve assembly 600b of Figure 6b is
shown having a bed 611c which is adapted to engage with a dove-tailed channel section
that may be incorporated into the base of a slat F as indicated in the Figure.
in Figure 6d, a further alternative arrangement of a flap valve assembly 600b is shown
comprising a bed 611d which is connected via a hinge 615 to a rigid flap 612d, the bed
611d being adapted to be fitted to the underside of a slat D. A spring means, shown as a
flexible bow 616, provided with a suitable means of attachment at its respective ends
extends between bed 611d and the underside of rigid flap 612d such that a displaced flap
is returned to its normal closed position once the passage of waste material through the
gap between adjacent slats is complete.
In Figure 6e a slat G is shown having an integrated member 621 which defines a pair of
spaced apart locating channels 622 on its opposing sides such that separately
demountable flap valves 612 which each comprise an elastomeric flap element 612a and
a mounting element 612b may be attached to the lower edges of said slat G.
Figure 7 shows an exemplary slat 700 which can be made from concrete, metal, plastic,
wood or other suitable material and which may be provided with elongate grooves 702 or
channels having various shapes e.g. dove—tai| 701 which may either be pre-formed or
incorporated into the slat and adapted to receive complementary shaped anchoring
formations provided on the respective mats or flap valves.
In Figures 8a and 8b, a sixth embodiment of a floor covering apparatus is indicated by the
reference numeral 710. Floor covering apparatus 710 comprises a domed elastomeric,
deformable upper mat portion 715 fixed to a bed 711 of a plastics material which has
sufficient rigidity to support the domed elastomeric upper mat portion 715 and an interior
cavity 714 which may be filled with a suitable deformable material. Upper mat portion 715
is of a low profile than the respective elastomeric, deformable mat portions of the previous
embodiments and comprises a domed upper surface that curves downwardly towards the
mat edges such that any urine and other animal waste matter deposited onto the floor
covering apparatus 710 would tend move towards the gap between adjacent slats.
Provision of such a curved upper surface may further serve to promote the movement of
animal waste from the mat thereby increasing the comfort of the animals thereon and
also helps preserve the slat itself by reducing absorption of urine into the concrete below.
In Figure 8b, an alternative arrangement of floor covering apparatus 710 comprises a bed
711 which includes a pair of laterally depending legs 713 formed in a shape having a
natural bias to grip the sides of a slat.
In Figure 9, an seventh embodiment of a floor covering apparatus is indicated by the
reference numeral 810. Floor covering apparatus 810 comprises a domed elastomeric,
deformable upper mat portion 815 fixed to a bed 811 of a plastics material which has
sufficient rigidity to support the domed elastomeric upper mat portion 815 which may
either be of solid construction or provided with a plurality of elongate holes 816. A bracket
818 which comprises a lower part 818a and flanges 818b extends into the gap between
adjacent slats D is adapted to engage the respective edges of adjacent mats 810.
Attachment of bracket 818a to mats 810 may be either with flanges 818b engaging with
recesses 817 provided along the edges of mats 810 or with flanges 818b in contact with
the surface of the outermost edges of mat upper portion 815. Upon tightening bolt 821
which extends through bracket 818 and expansion ring 822 into captive member 821
which is wedged between the respective sloping sides of slats D, bracket 818 is forced
downwards thereby clamping mats 810 to slats D.
Further enhancements may be made to any of the aforementioned embodiments of the
floor covering apparatus to augment the performance of the mats and their respective flap
valves as well to as improve the comfort and safety afforded to the livestock residing
thereon. Mats, 10, 110, 310, 410, 515, 715 and 810 are each suitable to receive surface
treatments that would include textured embossing or the addition of a further non-slip grip
surface made from a material applied either in the form of a complete skin or in the form of
beads or other similar textured features. The inclusion of such surface treatments would
also contribute to improved durability. The use of resilient elastomeric materials in the
construction of the flap valves allows the barrier formed by the valves to return to its
original closed position once urine and other waste materials have passed through the
floor slats so that gases and odours from a slurry tank below are prevented from
ascending upwardly though the barrier into the animal housing or reduced considerably.
Furthermore, employing elastomeric materials having a low friction surface finish
increases the transfer rate of said animal waste across said flap valves and into a slurry
tank or similar holding container below.
It is to be understood that the invention is not limited to the specific details described
herein which are given by way of example only and that various modifications and
alterations are possible without departing from the scope of the invention as defined in the
appended claims.
