Description
BACKGROUND OF THE INVENTION
[0001] The invention relates to a wood paving stone, especially, a
ready-to-install interlocking wood paving stone having a base body
with at least one top and bottom side, the top side forming the
walking surface and the bottom side forming the support surface of
the wood paving stone. The base body is a multi-layer structure
with one upper panel-like or block-like wood layer and at least one
support layer forming the bottom side of the base body. The wood
surface is installed in an interlocking manner.
[0002] Paving stones and surface coverings manufactured therefrom,
preferably interlocking paving of concrete stones or natural
stones, are sufficiently known in the art.
[0003] German Patent Number DE 31 44 559 A1 discloses a wood paving
stone comprising a smoothly ground top side as a walking surface.
The edges limit the top side being broken and a layer of a sealing
means is applied to the smooth top side. These wood paving stones
are manufactured from cross-cut wood. The bottom side opposite of
the smooth top side comprises longitudinal and crosswise slots cut
into the surface.
[0004] United Kingdom Patent Number GB 422005 further discloses a
one-piece wood paving stone of cross-cut wood that has lateral
distance elements or front-side recesses provided for interlocking
installation.
[0005] Based on this, it is an object of the present invention to
present a wood paving stone and a wood surface covering featuring a
long life as well as flexibility for diverse areas of
application.
SUMMARY OF THE INVENTION
[0006] An essential aspect of the wood paving stone according to
the invention is that its base body has a multi-layer structure and
the base body comprises one upper panel-like or block-like wood
layer and at least one additional support layer forming the bottom
side of the base body. The one upper panel-like or block-like wood
layer and the support layer are connected with each other directly
or indirectly. It is especially advantageous that the multi-layer
structure of the base body has an upper plate-like or block-like
wood layer and a support layer that enables the manufacture of wood
paving stones that are individually adapted to different
application conditions. A wood paving stone according to the
invention is understood to be a ready-to-install paving stone,
which can be installed in an interlocking manner, which has a
multi-part and/or multi-layer structure and whose plate-like of
block-like wood layer forming the walking surface is comprised of a
solid piece of wood, preferably of one piece or one part. The wood
paving stone according to the invention is further characterized as
having a long life and can be installed quickly and easily on a
variety of underlying surfaces. Interlocking installation with
joints also enables optional drainage of a wood surface covering
manufactured from wood paving stones according to the invention. It
is especially advantageous that the aforementioned layers can be
manufactured separately from one another and can then be joined
together for manufacturing the wood paving stone. The upper wood
layer and the lower support layer can be arranged either
congruently stacked one above the other, or offset against each
other, in order to produce a ready-to-install paving stone. Such a
wood paving stone is especially suitable also for heavy load
traffic.
[0007] It is especially advantageous that the upper plate-like or
block-like wood layer is manufactured from an impregnated wood,
preferably Dauerholz, robinia or acacia. The upper wood layer is
preferable manufactured from long-cut wood, namely as one part or
one piece. Dauerholz according to the invention is a wood, namely
pine or spruce that has been completely impregnated with a chemical
means, according to the method described in German Patent Number DE
102004020729B4, which is incorporated herein by reference. In this
method, pine or spruce wood with a wood humidity of at least 30% is
impregnated with at least one paraffin and/or wax as an
impregnating composition. The moist wood is immersed in the melted
impregnating composition and subjected to a temperature of the
impregnating composition between 110.degree. C. and 140.degree. C.,
so that the water emerges from the wood in the form of water vapor
and the wood is impregnated by the impregnating composition both in
the sapwood and in the heartwood. The wood humidity in the treated
wood is reduced to 20% or less and the wood is removed from the
impregnating composition in hot condition after completion of the
impregnation.
[0008] It is especially advantageous that the base body has a
thickness of at least 40 mm and the wood layer has a first
thickness between 15 mm and 60 mm, preferably between 20 mm and 30
mm. The lower support layer is comprised of a plastic panel with a
honeycomb-like structure or of a further preferably plate-like wood
layer or a wood sub-construction, the lower support
layer--regardless of the area of application--has a second
thickness between 10 mm and 30 mm, preferably between 12 mm and 25
mm. In the case of implementation of the support layer in the form
of a plate-like wood layer, the latter has a second thickness, for
example, of, 12 mm. The second thickness of a plastic panel with a
honeycomb-like structure on the other hand is, for example, 25 mm.
The honeycomb-like structure, according to the invention, is
understood to be a plastic panel with a plurality of mutually
intersecting connecting web sections, which due to the
intersections form a plurality of rectangular, triangular and/or
quadratic honeycomb openings.
[0009] In a further embodiment, there is accommodated between the
upper wood layer and the lower support layer at least one
intermediate layer. The layers are directly connected with each
other by gluing, screwing or pressing. Advantageously, the
intermediate layer has a damping and/or insulating effect and/or is
formed by a permanently elastic silicone layer, a Styrofoam layer
or a hard foam layer.
[0010] In a preferred embodiment, the wood paving stone comprises
lateral connecting means and/or distance lugs, the connecting means
being comprised for example of groove-shaped recesses and/or of
lug-shaped sections.
[0011] Further, it is advantageous that the panel-like or
block-like wood layer comprises a circumferential groove for
accommodating a sealing element, preferably a bead-shaped seal or a
sealing lip. The plate-like or block-like wood layer can also
additionally comprise a circumferential edge-side step on the
bottom of the wood layer.
[0012] In an advantageous embodiment of the ready-to-install wood
paving stone, the honeycomb-like plastic panel comprises a
plurality of mutually perpendicular first and second connecting web
sections, which are outwardly closed by a circumferential frame
section. The intersections of the first and second connecting web
sections produce a plurality of rectangular and/or quadratic inner
honeycomb openings and triangular edge-side honeycomb openings.
[0013] The terms "approximately", "essentially", or "about" as used
in the invention mean deviations from the exact value by +/-10%,
preferably by +/-5% and/or deviations in the form of changes that
are insignificant for the function.
[0014] Further embodiments, advantages and possible applications of
the invention are disclosed by the following description of
exemplary embodiments and the drawings.

DETAILED DESCRIPTION OF THE INVENTION
[0030] FIG. 1 shows, in a simplified schematic representation, a
longitudinal section through a wood paving stone according to the
invention that preferably is embodied in the form of an
interlocking wood paving stone, i.e. it can be installed in an
interlocking manner to form a surface covering.
[0031] The wood paving stone according to the invention comprises a
base body 1 having at least one top side 1.1 and one opposing
bottom side 1.2, which preferably are designed flat and parallel to
each other. The top side 1.1 forms the walking surface and the
bottom side 1.2 forms the support surface of the wood paving
stone.
[0032] The base body 1 further comprises, regardless of its
cross-sectional form, a plurality of flat and/or curved side
surfaces 1.3, 1.4, which preferably extend in pairs parallel or
mirror symmetric to each other and perpendicular to the top and
bottom side 1.1, 1.2, to enable the known method of interlocking
installation.
[0033] The base body 1 can in principle comprise any suitable
circumferential form for interlocking installation, i.e., the
teaching according to the invention is by no means limited to a
particular circumferential form of the base body 1. Preferably the
wood paving stones are installed in an interlocking manner so that
the side surfaces of adjacent wood paving stones adjoin each other
and produce between the latter a vertical joint, which after
installation of the wood paving stones is filled with a suitable
joint filling material, for example quartz sand or a similar
material, therefore forming a joined ground covering of wood paving
stones. In one embodiment of the invention the joints can be sealed
by a sealing element that is removably connected with the outer
side of the base body 1.
[0034] According to the invention, the base body 1 of the wood
paving stone has a multi-layer structure, i.e., it comprises at
least two firmly and mutually connected material layers 2, 3 which,
interlocking with the base body 1, constitute the wood paving
stone. After being manufactured, the wood paving stone is "ready to
install", i.e., the invention relates to a ready-to-install wood
paving stone, in particular, an interlocking wood paving stone. The
entire thickness D of the base body 1 from the top side 1.1 to the
bottom side 1.2 is at least 40 mm, preferably between 40 mm and 160
mm, depending on the assumed load capacity.
[0035] More particularly, the base body 1 comprises a wood layer 2
forming the top side 1.1 of the base body 1 and at least one
support layer 3 forming the bottom side 1.2 of the base body 1. The
wood layer 2 and the support layer 3 are arranged congruently
stacked one above the other, i.e., the support layer 3 is directly
or indirectly connected with the wood layer 2. The wood layer 2 is
panel-like or block-like in design and is manufactured from a
long-cut wood and/or from an impregnated wood, preferably
Dauerholz, robinia or acacia. Preferably, the wood layer 2 is
constructed as one piece or one part and therefore forms the load
bearing, solid part of the base body 1.
[0036] The wood layer 2 comprises, in a preferred embodiment, a
flat wood layer top side 2.1 and a flat wood layer bottom side 2.2,
which preferably extend parallel to each other. The panel-like wood
layer 2 has a first thickness D1 between 15 mm and 60 mm,
preferably between 20 mm and 30 mm.
[0037] The support layer 3 is comprised of a plastic panel with a
honeycomb-like structure or of a further wood layer. The support
layer 3 comprises a support layer top side 3.1, which is bound to
the flat wood layer bottom side 2.2 of the wood layer, and a
support layer bottom side 3.2. The support layer top side 3.1 and
the support layer bottom side 3.2 extend in planes oriented
parallel to each other. The support layer 3, depending on the
application, has a second thickness D2 between 10 mm and 30 mm,
preferably between 12 mm and 25 mm.
[0038] The top side 1.1 of the base body 1 forms the wood layer top
side 2.1 and the bottom side 1.2 of the base body 1 forms the
support layer bottom side 3.2, and in the case of a direct
connection of the wood layer 2 with the support layer 3, the
support layer top side 3.1 directly contacts the wood layer bottom
side 2.2 and is firmly connected with the latter.
[0039] In accordance with embodiments shown with reference to FIGS.
4-7, the wood layer 2 and the support layer 3 are connected with
each other either indirectly by at least one intermediate layer 4
by gluing, especially using a silicone glue or directly by screwing
or pressing. The connection of the intermediate layer 4 with the
wood layer 2 and/or the support layer 3 is likewise achieved by
using a suitable glue, by screwing means or by pressing the
respective layers 2, 3, 4 together.
[0040] As shown with reference to FIG. 7, the wood paving stones
can also comprise connecting means 5 in the area of the side
surfaces 1.3, 1.4, to produce a tongue-and-groove connection or a
plug-in connection. For this purpose, the support layer 3 and/or
the wood layer 2 comprises connecting means 5 in the form of
groove-shaped recesses and/or tongue-shaped protrusions in the area
of the side surfaces 1.3, 1.4 of the base body 1. The connecting
means 5 protruding outward from the side surfaces 1.3, 1.4 can also
form spacers for providing even joints in the event of interlocking
installation. Alternatively, lateral distance lugs can also be
provided in addition to the connecting means 5. The connecting
means 5 enable in particular immovable installation of the wood
paving stone in an interlocking system.
[0041] FIG. 1 shows a first embodiment of a wood paving stone
according to the invention, in which the base body 1 comprises a
support layer 3 in the form of a plastic panel with a
honeycomb-like structure. With reference to FIGS. 9 and 10,
preferably the support layer bottom side 3.2 and therefore the
openings of the honeycomb-like structure of the plastic panel form
the bottom side 1.2 of the base body 1. The top side 1.1 of the
base body 1 is formed in the depicted embodiment by the wood layer
top side 2.1, which preferably is smooth in design. The term
honeycomb-like, according to the invention, is understood to refer
to a plastic panel with a plurality of honeycomb openings 3', 3''',
which can have different opening cross sections. Preferably, the
surface enclosed by the honeycomb openings 3', 3'' is considerably
larger than the remaining surface of the plastic panel. The
honeycomb openings 3', 3'' have a triangular, quadratic,
rectangular and/or arbitrary polygonal cross-sectional form. Round
or oval cross-sectional forms are also possible, for example.
[0042] Alternatively, as shown in FIG. 2, for increasing the
non-slip properties of the paving stone, the wood layer top side
2.1 can have a structure of differing form and depth, for example
diamond-shaped, grooved or wavy. For this purpose, the wood layer
top side 2.1 is structure-planed. In the case of the embodiment of
the wood paving stone depicted in FIG. 2, the support layer 3 is
formed by an additional wood layer, namely by a plurality of
construction woods arranged at a distance from each other in one
plane and directly contacting the wood layer bottom side 2.2.
[0043] In a further alternative embodiment, according to FIG. 3,
the wood paving stone depicted in FIG. 1, for further increasing
the non-slip properties, is provided with a non-slip coating 6,
which preferably is applied to the wood layer top side 2.1 and
extends at least sectionwise over the latter. Preferably, the wood
layer top side 2.1 is provided completely with the non-slip coating
6, which can be a rubber coating or a melamine coating preferably
applied using the screen resist method.
[0044] In a further embodiment, according to FIGS. 4 and 5, there
is provided between the wood layer 2 and the support layer 3 an
intermediate layer 4, which preferably has a damping and/or
insulating effect. This intermediate layer 4 is formed by a
permanently elastic silicone layer, a Styrofoam layer or a hard
foam layer. The intermediate layer (or damping layer) 4, in the
case of implementation in the form of a silicone layer, has a third
thickness D3 between 3 mm and 10 mm, preferably between 4 mm and 8
mm. If manufactured from Styrofoam or hard foam, the third
thickness D3 is between 20 mm and 30 mm, preferably between 24 mm
and 28 mm.
[0045] FIG. 4 shows a wood paving stone according to the invention
with an intermediate layer 4 formed by a permanently elastic
silicone pad, which extends between the wood layer 2 and the
support layer 3, which is manufactured from a plastic panel with a
honeycomb-like structure and is connected directly with the
intermediate layer 4. The wood paving stone depicted in FIG. 4 is
intended for therapeutic or medical areas of application.
[0046] In the alternative, FIG. 5 shows a wood paving stone
according to the invention with an intermediate layer 4
manufactured from Styrofoam or hard foam, in which the intermediate
layer 4 again is accommodated completely between the wood layer 2
and the support layer 3. In this embodiment, the support layer 3 is
implemented in the form of an additional wood layer, on whose
bottom side 3.2 a plurality of groove-shaped recesses 7 are
provided for channeling of water. The wood paving stone according
to FIG. 5, due to the insulating effect, preferably is used in the
interior of a building.
[0047] In a further embodiment, according to FIG. 6, at least the
wood layer surface 2.1 is completely provided with a polyurethane
(PU) encasing 8, which can be manufactured, for example, by
over-molding. The PU encasing 8 can also extend over the end faces
of the wood layer 2 to the intermediate layer 4 and therefore form
a complete encasing of the wood layer 2, which, for example, is
acid-resistant, abrasion-resistant and/or "B1"-resistant. In the
embodiment depicted in FIG. 6, an intermediate layer 4 is provided,
which is manufactured from polyurethane and with the PU encasing 8
forms a complete and closed encasing of the wood layer 2.
Advantageously, a wood paving stone of such an embodiment can be
used in areas of application with increased hygiene requirements
and in diverse industrial areas. The PU encasing 8 has a layer
thickness between 3 mm and 5 mm, the first thickness D1 of the
panel-like wood layer in this application case being for example
ca. 30 mm.
[0048] FIG. 7 shows an alternative embodiment of the sectionwise
encased wood paving stone according to FIG. 6 in which the
connecting means 5 are integrated in the PU encasing 8 formed about
the wood layer 2. In accordance with the disclosed embodiment, the
connecting means are in the form of groove-shaped recesses
manufactured by suitable over-molding and/or outward protruding
connecting lug sections.
[0049] FIG. 8 shows exemplarily a schematic top view of the top
side 1.1 of a wood paving stone according to the invention with
lateral distance lugs 9, which are formed as one piece with the
wood layer 2 and/or support layer 3.
[0050] FIG. 9 shows exemplarily a schematic top view of a support
layer 3 formed by a honeycomb-like plastic panel. For direct
connection of the support layer top side 3.1 of the support layer 3
with the wood layer top side 2.1 of the wood layer 2, the latter
comprises a plurality of stud-like connecting pin sections 10,
which protrude preferably perpendicularly from the support layer
top side 3.1 of the honeycomb-like plastic panel 3.
[0051] In the present embodiment, the honeycomb-like plastic panel
3 comprises eight such stud-like connecting pin sections 10, which
are provided with circumferential retainer rings 10', to ensure
secure support of the latter in the corresponding bore holes 11 in
the wood layer bottom side 2.2.
[0052] FIG. 10 shows a cross section through the honeycomb-like
plastic panel 3 and FIG. 11 shows a schematic view of the wood
layer bottom side 2.2 with the prepared bore holes 11 for
accommodating the stud-like connecting pin sections 10. By pressing
the stud-like connecting pin sections 10 into the prepared bore
holes 11 the honeycomb-like plastic panel 3 is connected firmly
with the wood layer 2.
[0053] The honeycomb-like plastic panel 3 depicted in FIG. 9
comprises a plurality of first and second connecting web sections
3a, 3b extending perpendicular to each other, which are outwardly
closed by means of a circumferential frame section 3c. The
intersection respectively of the first and second connecting web
sections 3a, 3b produces a plurality of rectangular or quadratic
inner honeycomb openings 3', although the edge-side honeycomb
openings 3'' can also be triangular. The stud-like connecting pin
sections 10 are preferably molded onto the intersecting points of
the connecting web sections 3a, 3b. In the present embodiment the
inner honeycomb openings 3' are quadratic and have an opening width
between 2.5 cm and 5 cm. The connecting web sections 3a, 3b and the
circumferential frame section 3c preferably have the same web
width, which is for example between 2 mm and 5 mm. The
honeycomb-like plastic panel 3 depicted in FIG. 9 is especially
well-suited for installation of the wood paving stone on a sandy
surface.
[0054] In the disclosed embodiment the recesses 7 are formed by
slot-like openings in the circumferential frame section 3c, which
preferably are arranged on two mutually adjacent edge sides of the
honeycomb-like plastic panel 3. The other two edge sides of the
honeycomb-like plastic panel 3 comprise connecting means 5, which
have a T-shaped cross section and are molded onto the frame section
3c and also protrude outwardly from the latter. The connecting
means 5 and the recesses 7 are formed so that they engage
positively with each other and therefore are designed for
manufacturing a plug-in connection, in which case the T-shaped
connecting means 5 is inserted from above into the respective
slot-like opening 7 defining the recesses. In this respect the
short legs of the T-shaped connecting means 5 engage behind the
opposite sections of the circumferential frame section 3c forming
the slot-like opening 7.
[0055] In the present embodiment the honeycomb-like plastic panel 3
is rectangular and comprises on the opposing short sides two
slot-like openings 7 and/or connecting means 5, whereas four
slot-like openings 7 and/or connecting means 5 are provided on the
opposing long sides.
[0056] In an advantageous embodiment of the support layer 3
embodied as a honeycomb-like plastic panel, the support layer
comprises on the support layer bottom side 3.2 a plurality of
lug-like support elements 12, which protrude downward
perpendicularly from the support layer bottom side 3.2. The latter
preferably are molded onto the intersecting points of the
connecting web sections 3a, 3b and are therefore evenly distributed
over the support layer bottom side 3.2 of the honeycomb-like
plastic panel 3. The lug-like support elements 12 protrude
outwardly, preferably between 5 mm and 8 mm from the support layer
bottom side 3.2.
[0057] FIGS. 12 and 13 show alternative cross-sectional forms of
the wood layer 2 of a wood paving stone according to the invention
that is ready to install. The wood layer 2 depicted in FIG. 12
comprises two opposing semicircular front-side sections, which
respectively change via a quadrant-shaped front-side section into a
straight longitudinal side section. FIG. 12 shows the wood layer
bottom side 2.2 with the bore holes 11 provided for accommodating
the stud-like connecting pin sections 10. FIG. 13 shows a wood
paving stone with an H-shaped base body 1, whereas FIG. 1 shows a
top view of the wood layer top side 2.1 of the wood layer 2. The
outer external dimensions of the H-shaped base body 1 correspond
essentially to those of the rectangular wood paving stone depicted
in FIG. 11, whereas the opposing longitudinal side sections spring
45.degree. inward respectively to form a tapered middle area.
[0058] In a preferred embodiment the wood surface top side 2.1
forming the walking surface is provided with a non-slip coating 13
made of a plastic material. The non-slip coating 13 is formed for
example by a plurality of strip-like sections, which preferably are
arranged parallel to each other and along the longitudinal axis of
the base body 1. For this purpose a plurality of longitudinal
grooves can be incorporated into the wood layer top side 2.1, for
example, which are then molded with a plastic material, preferably
having a Shore hardness of approximately 85 and preferably
protruding slightly over the wood layer top side 2.1. Thermoplastic
polyurethane (TPU) can be used for this.
[0059] FIGS. 14 and 15 depict respectively, a schematic cutout view
of the corner area of an alternative embodiment of a plate-like
wood layer 2 of a wood paving stone. The wood layer 2 comprises a
circumferential groove 2.3, which is designed for accommodating a
sealing element (not depicted in the figures). The sealing element
can be bead-shaped or in the form of a sealing lip, which is
accommodated at least partially in the groove 2.3 and preferably
extends completely over the entire circumference of the wood layer
2.
[0060] Advantageously, during installation of the wood paving, this
results in optimal sealing of the wood paving stones against each
other, to produce a closed paving surface. This makes it possible
to eliminate the joint filling that normally is formed by a fine
sand mixture. Advantageously this prevents the escape of joint
filling material during cleaning of the wood paving covering.
[0061] Further, in the embodiments depicted in FIGS. 14 and 15, the
lower wood layer bottom side 2.2 provided for direct connection
with the honeycomb-like plastic panel 3 is stepped on the edge
side, namely so that the step 2.4 extends on the edge side from the
wood layer bottom side 2.2 in the direction of the wood layer top
side 2.1. The step width in this respect corresponds at least to
the second thickness D2 of the honeycomb-like plastic panel 3. The
step 2.4 is circumferential and serves for simplified insertion of
the connecting means 5, especially with a T-shaped cross section
into the recesses 7, especially slot-like openings of the
honeycomb-like plastic panel 3. The panel-like wood layers 2 of
FIGS. 14 and 15 have a different panel thickness and/or first
thickness D1.
[0062] Also, the edge from the wood layer top side 2.1 to the wood
layer bottom side 2.2 extends slightly inward, i.e., it is beveled
inward, namely preferably by an angle between 5.degree. and
10.degree.. This allows effective compensation of the swelling and
shrinking properties of the wood layer 2 at different temperature
and humidity conditions. This especially effectively prevents the
rising of the installed wood paving.
[0063] The invention was described above based on exemplary
embodiments. It goes without saying that numerous modifications and
variations are possible, without abandoning the underlying
inventive idea on which the invention is based.
