FLOOR MAT FOR ANIMALS
Abstract
A rubber or plastic floor mat for a stable, factory or the like,

Claims
I claim:
1. A floor mat comprising;
a generally flat sheet of resilient material;
a plurality of parallel rows of uniformly spaced protuberances
having substantially equal heights and extending downwardly from
the bottom surface of said sheet, the protuberances in adjacent
rows also being arranged in parallel rows;
a plurality of parallel rows of uniformly spaced protuberances
extending upwardly from the top surface of said sheet, the up and
down protuberances arranged in staggered relationship so that those
on one side of the sheet are disposed symmetrically between those
on the other side; and
a thickened border section integral with and extending along at
least a portion of the periphery of said sheet, said border section
extending downwardly from the bottom surface of said sheet at a
distance substantially equal to the height of the down protuberance
and having a plurality of transverse grooves extending over the
full width thereof, which are in communication with the spaces
between the down protuberances.
2. A floor mat according to claim 1 wherein said up and down
protuberances are hemispherically shaped.
Description
BACKGROUND OF THE INVENTION
The invention relates to a floor mat made of an elastic material
such as rubber or plastic sheet material, which mat is particularly
intended for covering floor surfaces in stables, factories and the
like.
Stable mats of rubber or similar elastic materials are known. Such
mats comprise, in general, at least at the lower side parallel
grooves for facilitating the removal of water or the like. It has,
however, appeared that the liquid removal is often insufficient, in
that the lower surface should be repeatedly cleaned, which is, in
the case of large and heavy mats, objectionable.
Such mats with a flat surface have the disadvantage that this
surface becomes slippery, so that, particularly when used as a
stable mat, the feet of animals and attendants have insufficient
grip on that surface. If, on the other hand, the surface is
grooved, the grip transversely of the grooves is improved, but such
grooves are quickly soiled, so that the advantage is quickly lost
if the upper surface is not repeatedly cleaned.
SUMMARY OF THE INVENTION
The invention provides a mat which does not have these
disadvantages, and it is an object of the invention to provide a
mat of this kind, which provides a sufficient grip at its upper
surface and, nevertheless, may be easily cleaned.
It is a further object of the invention to provide a mat of this
kind which presents a soft and flexible support to the feet or to
the bodies of lying animals, and which, nevertheless, has a uniform
and high load bearing capacity.
It is another object of the invention to provide a mat of this
kind, which allows an unimpeded removal of liquids accumulating
below the lower surface without retention of stagnant water.
A further object of the invention is to provide such a mat which,
by its flexibility and elastic support on the floor, provides a
pumping action causing a continuous removal of liquids accumulated
between the mat and the floor.
It is a last object of the invention to provide a mat of this kind
which comprises such border portions that several mats may be laid
on a floor with contacting edges without gaps between adjacent
mats.
The floor mat of the invention comprises at both sides a plurality
of projections, which, at each side, are arranged in a regular
array along at least two mutually intersecting series of parallel
lines, the projections at one surface being symmetrically disposed
between the projections at the opposite surface, the projections at
one side having all substantially the same height, one surface
being provided with an integral border portion which is thicker
than the mat between the projections and having a surplus thickness
which is substantially the same as the thickness of the projections
at that side of the mat, said border portion extending along at
least a part of the periphery of the mat.
BRIEF DESCRIPTION OF THE DRAWING
FIG. 1 is a perspective view of a mat according to the
invention;
FIG. 2 is a partial cross-section along the line II--II of FIG.
1;
and FIG. 3 is a plan view of a part of such a mat.
DESCRIPTION OF THE PREFERRED EMBODIMENTS
The mat shown in the drawing comprises, at its lower surface knobs
2 with a flat lower surface and having, in general, a circular
cross-section. As shown in FIG. 3 these knobs are arranged along
two groups of parallel lines intersecting at right angles. It is,
however, also possible to use a different arrangement, e.g. with
lines intersecting at a sharp angle or with more groups of lines.
At the opposite side rounded knobs 3 are provided which are
symmetrically arranged between the knobs 2 as shown in FIG. 3, and
having the same configuration. When a knob 3 is loaded, for
instance by the hoof of an animal, the mat will be deformed as
shown in FIG. 2, the material of the mat body being elastically
pressed into the hollow between the adjacent knobs 2 of the lower
surface. Thus a smoothly flexible mat surface is obtained providing
a soft support for lying and standing animals. Moreover a pumping
action is obtained in this manner at the lower side of the mat,
since, by the elastic deformations of the mat, the air and liquid
present between the mat and the underlying floor is kept moving,
the circulation and ventilation thus obtained being very favorable
for hygienic easeness. The rounded upper knobs 3 provide sufficient
grip for the feet of the animals, particularly when rising or lying
down, but these knobs do not promote the accumulation of dirt.
Moreover the interspaces between the rounded knobs are cleaned as
easily as a flat mat surface. The flexibility of the mat may be
less desirable in the border parts where a mat joins an adjacent
mat, the flexibility then causing gaps to be formed between the
adjacent edges of these mats when loaded.
In order to prevent this, the mat of FIG. 1 is, at least at those
sides bordering an adjacent mat, provided with a projecting lower
rim or border portion 4 extending as far as the lower knobs 2 from
the lower mat surface. The border portions of the mat are,
therefore, less flexible than the rest of the mat. In order to
maintain an unimpeded communication between the space between the
mat and the underlying floor, transverse slots or grooves 5 are
provided in the lower face of such a border portion, especially in
the case of a border portion surrounding the whole periphery of the
mat. These grooves 5 provide a communication between the interspace
between the knobs 2 and the surrounding. It is, however, possible
to omit this border portion at one or two edges of the mat.
The principal advantage of the air circulation provided by the
pumping action of such a mat is that the floor remains
substantially dry, and the air provides, in addition, a heat
insulation which is favorable for maintaining an agreeable
temperature near the floor, especially in the case of animals lying
on the floor mat.
The floor mat described and shown is only an example, and may be
varied within the scope of the invention. Instead of cylindrical
knobs 2 also polygonal or oblong knobs may be used, and the rounded
knobs may be replaced by cylindrical or polygonal knobs. Mats of
the kind disclosed may be manufactured from rubber or plastic sheet
material which is suitable for the envisaged use.
