Description
OBJECT OF THE INVENTION
[0001] As stated in the title of this descriptive specification,
the present invention relates to a device for joining parquet-type
plaques or pieces, with which notable advantages are contributed
compared to previous floors of this type and which includes means
of tongue-and-grooving between the different pieces.
[0002] It is an aim of the invention to achieve a novel form of
laying plaques or tiles and preferably parquet-type pieces that is
simple though which nevertheless presents a high level of finish
and termination.
[0003] It is also an aim of the invention to endow this type of
parquet with an additional technical advantage which would permit
the generation of a greater number of modulations and therefore
similar decorative effects to those which it is possible to achieve
with non-tongue-and-grooved parquet pieces, as is the case of
compositions in herring-bone.
PRIOR ART OF THE INVENTION
[0004] There currently exist a wide range of forms and systems of
laying a floor based on tiles that can be fitted together, but a
solid type of join is not achieved and, when it comes to longer
lasting floors, the pieces are not optimally intermeshed, or at
least they do not present a structure for the tiles or plaques and
the joining of pieces in general which, in accordance with the
present invention, leads to a form of laying parquet and similar
displaying major advantages compared to the current systems of
laying, above all in terms of the ease and intuitiveness of
installation, fitting of the pieces, and the inclusion of
joints.
DESCRIPTION OF THE INVENTION
[0005] The device in question is based on the classical pieces or
tiles constituting the floor or parquet, but endowed with certain
characteristic means of securing which is explained below.
[0006] The means of securing consist of certain angular projections
located in at least one of the sides of the piece, and which
collaborate with certain extensions or flanges to which they are
backed onto via their lower face, in order to be interconnected in
a tongue-and-grooved fashion and also intermeshed with the
recipient housings of the adjacent piece and which are found on the
opposite side of the pieces.
[0007] On this opposite side or edge provision is made for the
existence of some recesses at an angle, provided in association
with a lower flange which will in turn remain beneath the flange or
extension of the edge carrying the angular projections, according
to a tongue-and-groove connection in a coplanar-movement of the
pieces. In order to achieve total securing, one piece is displaced
slightly and in the perpendicular direction to that first movement
with respect to the other piece so that the end of the angular
projection by way of a hook penetrates into the end elbow of the
angular recess of the other piece or plaque.
[0008] Provision is also made for the upper or visible face of
these parquet type plaques or pieces and similar to have a plaque
of any type of pavement (ceramic, synthetic, natural etc.) backed
onto them.
[0009] In the second case, in other words, when the pieces have
another plaque of pavement backed onto them, some separation joints
are preferably included, for which the edges include a
corresponding machining. The joint has an inverted profile in the
form of a "T", the central pieces of which is located between the
adjacent plaques and the cross-piece is included in separate
openings of the parquet type plaques or pieces with these openings
being effected higher than the paracentral extension or connection
flange, in other words, very close to the upper face of the
parquet-type piece.
[0010] The other two opposite sides of the parquet-type plaques or
pieces are joined in a tongue-and-groove fashion but differently
from the above, due to one of the edges having at least one mortise
comprising two flanges collateral to it and able to be introduced
in other depressions of the opposite edge of the other piece or
plaque in a longitudinal fitting.
[0011] Provision has also been made so that, in the event of
fitting the parquet-type pieces according to a linear composition,
in other words, when the joints are arranged continuously, in order
to prevent sliding, a depression has been included in the form of a
corner piece, which is applied to the angular zone of two pieces at
their meeting point, with the pieces being thus perfectly
intermeshed together. One tab of the corner piece and part of the
other will remain inserted in the recess of the flange of one of
the pieces and the rest of this tab in the depression of the flange
of the plaque which occupies a diagonal position, being covered
with the plaque which closes the joining of the four pieces.
[0012] All the corner pieces remain hidden, of course, when the
tongue-and-grooving of the pieces is carried out in the formation
of the parquet-type floor.
[0013] In the intermeshed composition of the pieces, in other
words, when they are located in a quincunx, the blocking corner
pieces are not required because the array is kept very-stable and
blocked. When in particular the pieces have a rectangular shape,
the larger sides are the ones to bear the means of angular
engagement and the lesser sides bear the other type of engagement.
In these rectangular pieces, an intermeshed composition can be
carried out half-piece, with the pieces centered or in a quincunx,
or an intermeshed composition can be carried out in quarter-piece
or other variations that might be desired, since it all depends on
the number of angular projections and recesses existing.
[0014] In another form of embodiment, the parquet which the
invention proposes is made up of pieces that include some
connection projections in one of their edges and specifically in
the lower third of their thickness, and recipient recesses in the
opposite edge of an adjacent piece and also made in a flange in an
extension of the same lower third of the thickness of the piece.
The projections are located below a continuous flange emerging from
the central third of the thickness of the piece and this flange
will in turn be housed in a recipient groove of the opposite edge
of the adjacent piece in a linear or intermeshed composition of the
pieces.
[0015] The upper face or strip of the pieces can carry a ceramic or
similar plaque backed onto it by means of glue. It is also
considered that there could exist sealing joints interposed between
the ceramic plaques, said joints in that case having an inverted
"T" cross-section so that the central piece is located between the
adjacent plaques and the cross-piece is introduced into the
respective slots cut perimetrically in the upper third of the
thickness of the wooden or similar piece. Above the perimetric
slot, the wooden or similar piece will have a facing in order to
permit the accurate fit of the joint, with this facing
corresponding to the upper half of the central piece of that joint.
The ceramic plaques will of course have the dimensions
corresponding to those of the visible face of the lower piece.
[0016] The connection projections between the pieces are located in
two consecutive sides thereof and the corresponding recesses exist
in the two opposite sides to the previous ones. The shape of the
recesses and projections is identical to each other and have the
form of a obtuse angle triangle, the projections thus being
obliquely or diagonally shaped but in such a way that the
orientation of those located on one of the sides is inverted with
respect to those located on the other adjacent side.
[0017] This arrangement determines that the coupling between pieces
can be done by coplanar sliding of the new piece to be fitted with
a diagonal movement. So, the new installed piece will not bc able
to be removed unless it is displaced in the same diagonal direction
as it was introduced, since it will otherwise remain intermeshed.
It is no longer necessary to make compound displacements in order
to connect these pieces or tiles as used to occur with the
configuration of recesses or projections commented on earlier.
[0018] Another characteristic shown by this second form of
embodiment lies in the fact that the flange of the central third of
the thickness of the piece is continuously extended along both
consecutive sides, with the particular feature moreover that its
upper face ends in the form of a ramp descending towards the free
edge and slightly projecting beyond the connection projections
located beneath it.
[0019] Each of the opposite edges to said flanges iii extension of
the central third of the thickness has a recipient groove of
complementary cross-section made in it, in order to optimize the
fit between pieces.
[0020] The clips or "U" shaped engagement elements are also used
for achieving a better intermeshing of every two contiguous pieces
in the same row, for which the lower face of the pieces have some
angular notches cut in them which affect oily the lower third of
the thickness, one of which sections is arranged close to and
parallel to the adjacent sides and is made from the other opposite
sides. The other section which completes the angular shape of the
recipient notch of the "U" shaped clip affects solely the edge of
the end zones. When the two adjacent pieces have been fitted, the
clip is perfectly installed and remains flush with the edge without
obstructing the fitting of the new piece, whether the composition
is linear or intermeshed.
[0021] Provision has also been made for the upper or visible face
of the wooden or similar pieces to be covered with a ceramic or
similar plaque stuck with Adhesive. In this case, hermetic sealing
joints can be fitted between the plaques, such joints leaving the
form of an inverted "T" shape in cross-section, and in this case
the upper third of the thickness of the piece has a perimetric
facing in order to reduce the surface and which permits the joint
to be fitted between the two adjacent plaques. The joints have the
general form of an inverted "T" and the cross-member is housed iii
separate perimetric grooves made for the purpose in this upper
third of the thickness of the pieces.
[0022] In a third form of embodiment, the parquet, though it has a
structure similar to the previous embodiment mentioned and which
has the oblique projections of the lower third of the piece in two
of its adjacent sides, along with complementary oblique recipient
recesses in the other Bides, and flanges and slots in the central
third of the thickness, presents the advantageous characteristic
mentioned earlier in the section on object of the invention. This
consists of the fact that the number of different compositions of
the parquet can be increased without tongue-and-grooving, as with
herring-bone formations in the case of rectangular pieces.
[0023] To achieve this, according to the invention there are two
types of pieces involved in the formation of the parquet, both of
them being symmetric with respect to a perpendicular plane parallel
to one of their sides and with mirror symmetry. All the pieces have
the flanges, lots, oblique recesses and oblique projections, in a
symmetrical arrangement, and therefore the herring-bone formation
is achieved by alternating pieces of one type with those of the
other type in order to be able to fit the new piece in a position
rotated through 90.degree. with respect to the one previously
fitted of the type.
[0024] The same type of pieces cannot be used for producing
herring-bone formations.
[0025] In this case that has been commented on and which is of
preferred embodiment, the herring-bone formation is carried out
with pieces of both types in equal dimensions. Provision is also
made for the length of one type of piece to be a multiple of the
width of the piece of the other type and the width of the former to
be a divisor of the length of the latter. So, the pieces of one of
the types can be square and those of the other type rectangular of
lesser side having half the value of the side of the square, and
the larger side being double among other combinations.
[0026] In order to facilitate the understanding of the
characteristics of the invention and forming an integral part of
this descriptive specification, some sheets of drawings are
attached containing figures in which, on an illustrative rather
than limiting basis, the following have been represented:

DESCRIPTION OF THE PREFERRED FORM OF EMBODIMENT
[0063] Making reference to the numbering adopted in FIGS. 1 to 12,
the device for joining parquet type plaques or pieces, which the
invention proposes, permits the tongue-and-groove fitting of these
pieces in two perpendicular coplanar movements, one of approach and
the other of lateral sliding for the fit. FIG. 1 shows the joining
of plaques 1 in a linear combination (they are aligned in two
perpendicular directions, with the joints therefore coinciding) and
FIG. 2 shows a half-piece intermeshed composition.
[0064] To achieve this, the plaques 1 have in one of their larger
sides some angular extensions 2 as an extension of the lower face
and corresponding to a third of the total thickness of the piece,
as can be seen in FIG. 5. On the opposite side there exist
respective recesses 3 at an angle which have the same thickness
(one third of the total thickness of the piece 1), and of such u
size that permits the entrance of the angular extension 2 and its
subsequent lateral displacement so that the angular pieces
interconnect and secure the join. The angular extensions or
projections 2 remain backing on below the central rim 4 of that
edge and the recesses 3 eliminate the wall of the lower flange 5
defined in tore lower third of the thickness of the plaque 1.
[0065] The paracentral flange 4 (central in the case shown in the
figure, since, as we have said, the thickness is approximately one
third of that of the plaque 1), projects with respect to the upper
or visible face of the plaque 1, this upper face being perfectly
rectangular as can be seen in the fitting of plaques 1. Said flange
4 will remain introduced in the groove 6 of the opposite edge of an
adjacent piece, as can be seen more clearly in FIGS. 7 and 8. The
visible face is referenced with the number 7 and the lower or
hidden face with the number 8.
[0066] In FIG. 7 the connection in two perpendicular movements can
be seen for engaging the angular extensions 2 in the recesses 3.
The furthermost recess 3 of those existing also remains open at the
contiguous edge owing to the proximity to the corner of the
plaque.
[0067] What has been mentioned so far in this section permits
connection between the plaques 1 via their longitudinal or greater
edges in this example of rectangular plaques 1.
[0068] The connection via the lesser edges is also carried out in a
precise manner due to the existence in one of them of the flanges 9
formed on one and the other side of the mortise 10, in the same
lower plane as the flange 5, said flanges 9 being introduced in the
mortised depressions 11 of the opposite edge of an adjacent plaque,
to one side and the other of the trapezoid projections 12
intermediate between them, in a linear movement simultaneous to the
lateral displacement for entrance of the elbows of the angular
projection 2 and angular recess 3.
[0069] Making special reference now to FIGS. 9 to 12, we see an
example of embodiment with square plaques 1' which possess in their
upper or visible face a ceramic or similar plaque 13, stuck to them
by gluing. In this case we can seen how the edges of the wood have
been machined in an inverted "T" for the joint 14 of identical
cross-section, and The central piece of that joint is extended
until it is practically flush (or remains slightly tucked in) with
the visible face of the plaque 13. The joint 14 fits perfectly into
the sides of the ceramic plaque 13 due to having small co-lateral
oblique tabs which can be seen in the drawings.
[0070] The joints 14 are finished in a double bevel in order to
solve the meeting points (see FIGS. 9 and 10) when the fitting of
the plaques is done adapting a linear composition. If the fitting
is half-piece intermeshing (FIG. 12) the joints 14 are straight
because they make end to end contact against each other in the
longitudinal lines which are continuous and also in the transverse
or perpendicular sections between them.
[0071] In FIGS. 1, 6, and 7 we see a linear composition of plaques
1 and in FIG. 2 a half-piece intermeshed composition since the
pieces 1 are arranged centered in a quincunx. With this geometry of
plaques 1, a quarter-piece intermeshing can also be carried out
simply by making the connection between plaques more out of phase
by selecting other connection recesses for the engagements at an
angle.
[0072] Finally, in the linear composition of plaques, both of the
type 1 and of the type 1', a perfect intermeshing is achieved by
locating the corner pieces 15 (FIGS. 1, 6, 10) in the depressions
16-17 which, when they coincide, form the recipient depression for
that corner piece 15. Such corner pieces become perfectly hidden
when the filial piece is laid which closes the meeting of four
pieces or plaques 1 and 11.
[0073] Making reference now to the numbering adopted in FIGS. 13 to
24, we can see that the parquet which the invention proposes is
formed in this second example of embodiment with square-shaped
pieces referenced in general with number 18. The visible face is
referenced with number 19 and the hidden face with number 20.
[0074] In the enlarged details of FIGS. 16 and 17, it can be seen
that the thickness of the pieces 18 is divided into three parts
which can be equal or different. The upper third is referenced with
number 21, the central one with number 22 and the lower with number
23.
[0075] The connection projections between pieces 19, made between
the lower face 20 and which occupy the lower third 23, are
referenced with the number 24 and are to be found on two adjacent
sides and below the flange 25 which is continued along both
adjacent or consecutive sides. The upper face of this flange is
referenced with 26 and it shapes a ramp which facilitates the
entrance of said flange 25 in the groove 27 of the respective
opposite sides of the piece 18, as can be seen in the enlarged
detail of FIG. 16. The coupling of two adjacent pieces is more
clearly seen in FIGS. 22 and 23, which respectively show the
position before and after the coupling.
[0076] The recesses corresponding to the projections 24 located on
tile respective opposite sides and also consecutive with each other
are referenced with the number 28, and there exist four recesses 28
and a further four projections 24 in the contour of the pieces 18,
in facing positions.
[0077] The recesses are made in the edge of the flange 29 located
in an extension of the lower third 23 of the thickness of the piece
18, in two of the corresponding consecutive sides, as is seen in
the enlarged detail of FIG. 16 which corresponds to an elevation
view of FIG. 15.
[0078] Note that the projections 24 and the complementary recesses
28 all have the shape of an obtuse angle triangle adopting an
oblique arrangement in the same diagonal direction of the pieces
18, which means that the pieces can only be coupled in this
diagonal direction since they enter perfectly centered. Both also
have their edges rounded for that same purpose.
[0079] Making special mention of FIGS. 14 and 21, in order to
ensure the immobility of the pieces 18 of the parquet, clips 30 are
located in the angular notches 31 of perpendicular sections 32 and
33 which, in the assembly of two pieces, shape the recipient
housing for the clip 30, the angular notches 31 affecting solely
the lower third 29 of the thickness of the piece. The sections 32
are made solely in two of the opposite sides of the pieces 18 and
in proximity to the other two sides thereof. The sections 33 affect
just the edge of the end zones of these same sides. In FIG. 21 one
of the clips is already fitted and it can be seen how a blocking is
produced in alignments of pieces in a linear composition, while in
FIG. 24 an assembly can be seen following an intermeshed
composition of the pieces 18. The central part of the clips 30 do
not project from the edge from which the projections 24 emerge in
order not to hinder the fitting of the other adjacent piece.
[0080] The clips 30 have their arms slightly converging in order to
facilitate the progressive insertion. The clips 30 on the sides of
the recesses 28 are seated in a front or facing machining of the
lower flange 29 which cuts the length of the tab precisely to the
degree of the thickness of the central part of that clip 30.
[0081] In the third form of embodiment of the invention, according
to FIGS. 25 to 40, we can see that the parquet is formed as shown
in FIGS. 2S and 26 with two types of pieces in order to be able to
produce intermeshed or herring-bone assemblies where some
rectangular pieces, equal in their dimensions in this case, adopt
an arrangement rotated 90.degree. with respect to the ore which has
previously been laid.
[0082] The pieces of tiles of one type are referenced with number
34 and those of the other type with number 35, the latter being
highlighted by means of stippling.
[0083] The pieces 34 offer the geometry shown in FIGS. 27 to 31,
and the pieces 35 that shown in FIGS. 32 to 36.
[0084] The pieces 34 and 35 are symmetric with respect to a
vertical plane, in other words, they have mirror symmetry, as we
will see further below.
[0085] The pieces 34 present a visible or upper surface 36 with
straight edges and a lower one 37 with some oblique projections 38
in two of their contiguous sides, and complementary oblique
recesses 39 in the other two sides.
[0086] The oblique projections 38 have a thickness corresponding to
the lower third of the thickness of the pieces 34, and they are
backed on below the paracentral flange 40 which emerges from the
central zone of the thickness of the piece, in just two of these
contiguous sides. In the other two opposite sides there exist a
corresponding slot 41 which will receive the flange 40 in the
tongue and groove coupling.
[0087] The recesses 39 are made in the flange 42 which projects out
in the lower third of the thickness of the pieces 34 being extended
along the corresponding adjacent sides, these recesses being
located below the paracentral flange 40 in the corresponding
section in which they overlap when being laid and will in turn
remain introduced in the recesses 39. As the projections are
oblique in the same way as the recesses, the coupling is carried
out with a diagonal approach of the new piece to be laid.
[0088] For their part, the pieces 35 possess the same geometrical
characteristics in terms of flanges (40, 42), oblique recesses 39,
oblique projections 38 and slots 41, but with all of them arranged
symmetrically, as can be deduced from making a parallel comparison
of FIGS. 27, 28 and 30 of pieces 34, with 41, 42 and 44 of pieces
35.
[0089] If, for example, we place FIG. 26 to the left of FIG. 35, we
can see how, as a consequence of the symmetry they show, the
oblique projections 38 and the oblique recesses 39 of the piece 34
on the left have inverted orientations with respect to those of the
right. As what is wished is to form the parquet by intermeshing the
pieces 34 and 35 in the form of a herring-bone, the connection is
perfectly made by rotating the pieces 35 through 90.degree. in the
clockwise direction. In the example of embodiment shown in FIGS. 25
to 36, where the pieces 34 and 35 intervene, the laying of the
parquet is done as seen in FIGS. 37 and 38. As the pieces 34 and 25
have two recesses and two projections in the respective greater
sides and just one recess and one projection respectively and
centered in the lesser sides (the length of the pieces is double
their width), the connection is perfectly made due to each
projection 38 and recess 39 in the connection having the same
orientation. In FIG. 39 this assembly can be seen from the lower
face which is where the projections and recesses are to be found.
Using just pieces of the type 34 or pieces of the type 35, this
connection in a herring-bone (intermeshed composition) cannot be
made, and a parquet can only be laid with pieces connected linearly
in rows (linear composition).
[0090] Finally, in relation to FIG. 40, we can see a parquet formed
from square pieces of the same type au the pieces 34 (therefore
referenced with 34') and rectangular pieces of the type of pieces
35 (therefore referenced with 35') and which are only symmetric in
terms of the arrangement of tabs, slots, recesses and projections,
but not in terms of their dimensions. In this case, the pieces 34'
are double the length of the pieces 35' and their width is half
that of the sides of the latter.
