TILE FOR COATING AND DECORATING SURFACES
Abstract
A tile for coating and decorating surfaces includes a slab which
is of rigid material of light weight capable of adopting any
polygonal shape having an even number preferrably four sides. Ribs
extend peripherally around the slab perpendicular to the rear
surface thereof. Two adjacent sides of the slab each have a pair of
identical projections extending therefrom. The projections are
centrally perforated. The two other adjacent sides of the slab each
have a pair of female recesses for coupling with the lugs of
adjacent slabs to form the coating. The rear surface is provided
with reinforcement ribs, which form an air insulating chamber. A
plate of insulating material is located on the edges of the ribs.
The top surface of the slab is bevelled and is coated with a
colored sheet and a thin coating made of transparent and waterproof
material which protects the top surface.

Claims
I claim:
1. A tile for covering and decorating surfaces, said tile
comprising:
a rectangular slab formed of a light weight rigid material and
having four edges, two adjacent of said edges each having a pair of
fins extending outwardly therefrom, each of said fins having a
tubular projection extending from the upper surface thereof, each
of said projections having a longitudinal opening therethrough, the
other two adjacent of said edges each having a pair of crevices
extending inwardly therefrom, each of said crevices having a
cylindrical recess extending upwardly therefrom, said slab on the
rear surface thereof having a plurality of spaced reinforcing ribs;
and
a plate of insulating material attached to said ribs on said rear
surface of said slab, thereby providing recesses between said slab
and said plate for the passage of electrical installations.
2. A tile as claimed in claim 1, wherein said edges of said slab,
from the front surface thereof, are bevelled, and further
comprising a decorating sheet of attached to said front surface,
and a thin coating of transparent material covering said decorating
sheet.
Description
The present invention relates to improvements in the manufacture of
tiles for decorating and coating purposes in buildings.
An object of the invention is to provide a tile constituted by
three essential parts:
A flat and rigid body or slab made of plastic or similar material,
having preferentially a square shape. Two adjacent sides of this
body each have a pair of fins in form of square sectioned elements
which protrude to the exterior of the edges of the slab. These fins
present hollow coupling projections, perpendicular to the obverse
of the slab. On the other two adjacent sides of the slabe there are
pairs of crevices for the fins of adjacent slabs and having
recesses for their projections.
On the obverse of the slab, there is attached a decorated or
colored sheet protected by another transparent waterproof and very
thin sheet; and
On the reverse, there exists a plate made of insulating material,
whose shape coincides with the inside area of the slab. Such plate
has on its edges notches or fittings for the projections of the
fins, which at the same time serve to fix the plate to the
slab.
The characteristics of the improved arrangement of the slabs
claimed will now be defined with reference to the attached drawings
which only correspond to one embodiment. It should be understood
that the accompanying drawings are presented as a way of example of
one embodiment, since the shape, dimensions and materials with
which the different parts are manufactured, will in each case be
those that are deemed pertinent for the specific use dealt with.
The slabs for decorating and coating purposes which are
manufactured according to the general inventive idea expounded, and
any possible modifications, will not be more than variants likewise
comprised and protected by the present invention, within the scope
of the claims.
FIG. 1 shows a rear view of a slab, partially sectioned to show its
inner portion.
FIG. 1A is a side view of the slab.
FIGS. 2 and 3 respectively show sections indicated at section lines
A-B and C-D of FIG. 1.
FIG. 4 is a plan view from the upper part of a slab on a smaller
scale.
FIG. 5 is a perspective view showing an enlarged detail of a corner
of the slab.
FIG. 6 is a partial longitudinal view in section showing how
assembly is effected between two adjacent slabs.
In the drawings the slab 7, FIGS. 1 and 4, has on two adjacent of
its sides, joining fins 1 which in turn have tubular projections 2
with holes 8 therethrough, FIGS. 1 and 3. On the other two adjacent
sides there are joining cut-out portions or crevices 3 having
recesses 5 therein for receiving the tubular projections 2.
In FIG. 1 is shown a plate 4 of polyurethane foam or similar
material which fits over the rear side of slab 7 in contact with
ribs 6 thereon. On the obverse side of slab 7 the decoration can
for example be consituted by the chromo, design or picture, etc.
10, protected by the coating 9 of polyester, the shape of the slabs
being bevel-edged as indicated at 11.
In FIG. 6 the coupling between each fin 1 and the corresponding
crevice 3 is shown, the details of which have already been outlined
in FIGS. 2 and 3.
This description corresponds to the general arrangement of the
slab, which can be manufactured according to the following
description. There exist various embodiments, but the principle
ones are the following:
The insulating element 4 which constitutes the reverse of the slab,
may be made of cork, polyurethane foam, expanded polystyrene, or
any other product, such as melted glass wool;
The fins 1 of the slabs and the projections 2, for as well as the
corresponding crevices 3 and recesses 5, can be of any arrangement
to guarantee the adequate joining of a plurality of slabs placed on
a surface;
The principle element, that is the slab 7, has on its obverse,
exteriorly, a contacting adhesive, protected by an outer sheet
which could have millimetric indications in order to cut off
pieces.
The slabs 7, when deemed necessary, may have spaces due to ribs 6
for the passage of aerials, cables, etc.
The projections 2 with openings 8, serve to hold the slabs, nailing
same to wood, walls etc. should an adhesive for its fixing not be
desired.
The outer part of the slab may have any arrangement which serves to
reflect light or produce any of the known effects, which increase
the attractiveness of the decoration.
It should be noted that, besides the general characteristics
expounded of the body of the slab, the ribs, normally having a
quadrangular shape, are arranged with regards the slab in such a
way that they have common diagonals and leave hollow openings with
the insulating plate. This arrangement has the additional advantage
of conferring both insulating and reinforcing properties.
