A TILE WHICH IS TO BE USED FOR COVERING SURFACES
FIELD OF THE INVENTION
The present invention relates to a tile which is to be used for covering
surfaces such as sloping roofs or walls, said tile comprising a central part
with a first-end and a second-end. Further, the present invention relates to a
roof element which is to be used for covering surfaces such as a sloping roof
or walls. Further, the present invention relates to a system comprising at
least one tile and at least one roof element, said tile comprising a central
part
LO with a first-end and a second-end, and said roof element having a first-end
or
a second-end or a combination of these. Further, the present invention
relates to a surface such as a sloping roof or wall provided with tiles, said
tiles comprising a first-end and a second-end and are mounted to parallel
and spaced apart battens and wherein the arrangement of the tiles is
L5 transverse to said battens.
BACKGROUND
Tiles are well known for use in a sloping roof for constructing the outmost
layer of the roof. There are mainly two issues that have to be fulfilled when
2 0 using such tiles. Firstly, that rattling and falling of the tiles from the
roof are
prevented under different weather conditions, and secondly that a sufficient
tightening on the roof is provided. In prior art methods this is fulfilled by
mounting the tiles securely to the battens and mutually together. The
mounting to the battens is typically done by nailing or screwing the tiles to
the
25 battens and secure them individually together e.g. by using tile hooks. The
disadvantage with the tiles of prior art is how time demanding it is to
arrange
and mount the tiles together and the complications that follow the nailing of
the tiles to the battens and mounting them individually by using said tile
hooks.

This has partly been solved in the utility model DE 29713683 which describes
a roof tile comprising a u-shaped engagement means for engaging with a
batten and thereby replacing said nailing or screwing when mounting the tile
to said batten. However, this reference does not mention how said tile is
mounted to the subsequent upper/lower laying tile in order to make the
installation of said tile completely free of external tools.
OBJECT AND SUMMARY OF THE INVENTION
It is therefore the object of the present invention to provide tiles, which
are
much simpler in use and which do not require nailing and tile hooks or similar
means when mounting them to the battens and individually together. Another
object of the present invention is to provide a roof element which is to be
used for covering surfaces such as a sloping roof or walls. Still another
object
of the present invention is to provide a system comprising at least one of
said
tile and said roof element. Yet another object of the present invention is to
provide a surface such as a sloping roof or wall provided with said tiles.
In one aspect the present invention relates to a tile characterized in that
said
tile is adapted to be mounted to said surface based on engagement means
comprised in said first-end and second-end.
Thereby, since no external means such as nails, screws or hooks are
required when mounting such tiles to a batten, the mounting is much easier,
simpler and faster.
In an embodiment, the engagement means at the first-end of said tile is
adapted for mounting said tile through a snap engagement with a batten.
In that way the installation of the tile is very comfortable and simple and
additionally provides a strong mounting between said batten and said tile.

In one embodiment the engagement means at the second-end is adapted for
mounting said tile by engaging with at an adjacent first-end of a neighboring
tile.
Thereby, the neighboring tile provides means for mounting or securing the
second-end of the tiles so that nails, screws or hooks or the like are not
necessary.
In one embodiment the first-end comprises a nose part, a grip part being
upwardly extending towards said nose part, and a front plate for
interconnecting said nose part and said grip part, and which is substantially
perpendicular to said central part.
Thereby, the tile can be mounted to a batten simply through engagement
between the first-end and the batten so that the batten is propped between
said nose part and said grip part. Therefore, it is preferred that the
distance
between the nose part is substantially the same as the thickness of the
batten.
In an embodiment, the first-end comprises a back side plate and a top plate
that are, respectively, substantially perpendicular and parallel to the
central
part and a nose part that extends towards the second-end from said top-
plate.
Thereby, a space is created to enable an engagement between the first-end
and a batfien. Also the nose part provides an engagement means for the
neighboring tiles.
In one embodiment the second-end comprises a tail extending partly in an
upward and outward direction in relation to said central part and is adapted
to
CA 02572876 2007-01-04
WO 2006/005339 PCT/DK2005/000474
4
be secured at said adjacent first-end of said neighboring tile by means of
clamping the tail between a batten and the neighboring nose part.
Thereby, an angle x is formed between said tail and said central part so that
when said tail is clamped between said batten and said neighboring nose
part, the subsequent part of the tile will extend in a similar partly upward
direction in relation to the neighboring plate. This is important for the snap-
engagement feature since the elastic force that is created when pushing the
tile towards the neighboring batten provides an upwardly extending force
Zo between the grip part and the lower plane of the batten. The tail may be
formed by bending at least a part of one end of an initial plate in said
upward
direction, or the tail and the central part can be two separated units which
are
interconnected by a spring system, such as a spring coil or the like. In the
former case the elastic force can be varied by varying the angle x, the
.15 thickness of the plate, the material type of the tile or a combination of
these.
In this case it is important that the material property of the tile is such
that it
has an elastic character and high strength. In the latter case, the elastic
force
can by varied by varying the angle x or the spring constant, or a combination
of both. An example of material that could be used in the tile is any kind of
20 metal such as aluminum, copper, metal alloys or composite materials. Also,
different types of plastic materials or the like are possible.
In one embodiment the second-end comprises an engagement crook
adapted to be secured at said adjacent first-end of said neighboring tile by
25 means of engaging with the neighboring nose part of said neighboring tile.
It is thereby ensured that said second end is strongly secured to said
adjacent first-end of said neighboring tile. Further, the engagement between
neighboring tiles becomes very simple and fast.
CA 02572876 2007-01-04
WO 2006/005339 PCT/DK2005/000474
In an embodiment, the material of said tile has high elasticity. Such high
elasticity is preferred for the present invention for obtaining said snap
engagement feature. An example of material having such property is
aluminum, copper, metal alloys, composite materials and different types of
5 plastic materials and plastic alloys.
In an embodiment the central part comprises a substantially flat plate.
Therefore, when arranging a plurality of tiles together,, a substantially flat
roof
construction is obtained which prevents or reduces the generation of e.g.
snow and ice on the roof. Of course, the central part can have different
shapes, such as a wave like shape.
In another aspect the present invention relates to a roof element
characterized in that said roof element is adapted to be mounted to said
surface based on engagement means comprised in a first end.
Thereby, the construction of roofs using such roof elements is simplified,
easier and much faster. The roof element can as an example comprise a roof
top or a gutter. In the former case, the roof element may have two such first-
ends on each side of the roofs, which are mounted to two battens and which
are simultaneously adapted to secure the tail part of the upmost row of said
tiles. In this case the roof element could comprise a nose part having
substantially the same shape as the nose part of said tile, and which would
be adapted to clamp the tail part of said upmost row of tiles between said
nose part and said battens. The roof element could also as an example
comprise a frame work surrounding a window that is to be built into the roof.
For such a roof element, the upper and the lower part of the framework would
preferably comprise a second-end or a first-end to engage with the tiles
arranged above and below the framework. Thereby, a roof element is
provided for interconnecting with said tiles.

In an embodiment said roof element further comprises engagement means at
a second-end of said roof element for mounting said roof element, where
said engagement means is adapted to be secured at an adjacent first-end of
a neighboring roof element or a neighboring tile.
Thereby, means for mounting or securing the second-end of the roof element
is provided, and e.g. nails, screws or hooks or the like are not necessary.
In an embodiment a second-end of said roof element is adapted to be
mounted to a neighboring batten through a snap engagement.
This provides a strong engagement between said second-end and said
batten. Also, no external tools such as nails, screws or hooks or the like are
necessary which makes the mounting very comfortable.
In a third aspect, the present invention relates to a system characterized by
that said tile and said roof element is adapted to be mounted to said surface
based on engagement means comprised in said first-ends.
Thereby, when constructing the top layer of a sloping roof, different areas
can be interconnected with the tiles. An example is a roof top and the
subsequent part of the roof, a frame work surrounding a window and the
surrounding part of the roof and a gutter and the subsequent part of the roof.
In an embodiment said first-ends are adapted to be mounted to battens
through a snap engagement.
In an embodiment the second-ends are adapted to be secured at adjacent
first-ends of neighboring tiles or neighboring roof elements.

In an embodiment, the second-ends are adapted to be mounted to
neighboring battens through a snap engagement.
In a fourth aspect the present invention relates to a surface such as a
sloping
roof or walls provided with tiles characterized in tiles are mounted by
engagement means comprised in said first-end and second-end.
Thereby, when constructing the outmost layer of e.g. a roof, no fastening
means are needed to mount the tiles to the battens. It follows that the
construction of the outmost layer of the roof is much faster and simpler.
Preferably, the tiles are of the type as discussed here above.
In an embodiment, said tiles are mounted by a snap engagement between
the first-end and the battens.
In an embodiment the second-end is secured at the adjacent first-end of the
neighboring tile.
Thereby, means for mounting or securing the second-end of the roof element
is provided, and e.g. nails, screws or hooks or the like are not necessary.
In an embodiment the second-end is mounted to neighboring battens through
a snap engagement.
Thereby, besides the absence of said nails, screws or hooks or the like the
mounting is very comfortable.

DESCRIPTION OF PREFERRED EMBODIMENTS
Figures 1 - 3 show a perspective view, a side view and a front view of one
embodiment of a tile 1, which is to be used for covering surfaces such as a
sloping roof or walls. The tile 1 comprises a central part 7, which comprises
a
substantially flat plate of length 1 13 and width w 12 with a first-end 14 and
a
second-end 15 extending along the width 12 of the plate 7. As shown, the
second-end 15 comprises a tail 2 extending partly in an upward direction in
relation to the plate 7 and forms an angel x 33 in relation to the plate 7.
The
first-end 14 is adapted to engage with a batten (not shown) and comprises a
nose part 5, an upwardly extending grip part 4 and a front plate 3 which is
substantially perpendicular to the plate 7 for interconnecting said nose part
5
and said grip part 4.
Any other kind of shape of the second-end is of course possible. In one
embodiment the first-end and the central part form a substantially flat plate
(not shown) so that the first-end may be considered as an extension of the
central part.
The tile 1 may be formed from a single rectangular plate by using an
appropriate forming machine. However, any kind of plate form would also be
possible. When forming the second-end 15, i.e. the tail 2, at least a part of
one end of the plate is bended upwards until said angle x 33 is formed. When
CA 02572876 2007-01-04
WO 2006/005339 PCT/DK2005/000474
the first-end 14 is formed, it is initially bended downwards (compared to the
tail 2) and towards the second-end 15 to form the nose part 5, thereafter
downwards and substantially perpendicular to the plate 7 to form the front
plate 3, and finally in an upward direction and towards the nose part 5 to
form
5 the grip part 4. It is, however, also possible to form said tile 1 through
separated parts comprising the first-end, the second-end and the central part.
These parts could be interconnected together through e.g. a spring system
such as a coil spring.
10 As shown in Figs. 1 and 3, the grip part 4 and the front plate 4 are cut
into
parallel strips to form a plurality of bendable flaps 6. This is necessary
when
mounting the tile I to a batten (not shown) where another batten crosses said
batten. The width of the flaps as well as the distance between neighboring
flaps and the number of flaps can of course be varied, depending on the type
of the surface to be covered. This will be discussed in more detail under fig.
9.
Figure 4 shows two neighboring tiles 1, 8 mounted together between two
parallel battens 32, 18. As shown, the tail 17 of the neighboring tile 8 is
clamped between the batten 32 and the nose part 5. Since the tail 17
extends partly in an upward direction and forms said angle x 33 in relation to
the plate 7, the subsequent part of the tile 8 will, due to the clamping,
extend
in an upward direction under substantially the same angle x 33 in relation to
the upper plane of the batten 32. The mounting of the tile 8 with the batten
18
is performed by pushing the tile 8 downwards and towards the batten 18 as
indicated by the arrow 30, until the grip part 34 reaches the lower plane of
the
batten 18. The elastic force that follows the pushing in the opposite
direction
of the arrow 30 ensures a strong engagement between the grip part 34 and
the batten 18. This is illustrated more clearly in Fig. 5 showing where the
neighboring tile 8 has engaged with said batten 18. Clearly, in order to reach
the lower plane of the batten 18, the grip part 34 must be bended upwardly
CA 02572876 2007-01-04
WO 2006/005339 PCT/DK2005/000474
11
as it crosses the side of the batten 18. After crossing the side the grip part
34
is flipped back into it original position and crooked to the bottom of the
batten
18 as shown. It is therefore very important that the material of the tile 8
(or at
least the grip part 34) has a good eiasticity. Accordingly, the distance
between the outwardly standing end of the grip part 34 and the nose part 37
is preferably substantially the same or somewhat more than the height of the
batten 18. By releasing said pushing as the elastic force is released so that
the grip part 34 of the tile 8 is pressed in with a force corresponding to the
elastic force having an upward direction as indicated by the arrow 16.
Therefore, a snap engagement is obtained.
This elastic force, and therefore the strength of the snap engagement, may
be controlled by varying following parameters: the angle x 33 between the tail
17 and the plate 35, the thickness of the material, the material type of the
tile
or a combination of these. It is important that the material property of the
tiles
is such that it has an elastic character and high strength. An example of
material that could be used is any kind of metal such as aluminum, copper,
metal alloys or composite materials. Also, different types of plastic
materials
or the like are possible.
In an embodiment where the tail 17 is in the same plane as the central part 7
and forms an extension of the central part, a rubber list (not shown) or
similar
means could be provided between the tail 17 and the nose part 37 so that a
sufficient tightening there between is obtained.
Figures 6 shows a closer view of the engagement between said neighboring
tile 8 and the tile I shown in Fig. 4. Here the tail 17 of the neighboring
tile 8
has been clamped between the baften 7 and the nose part 5.
Figure 7 shows a side view of the tile 1 extending between two parallel
battens 19, 20 on a roof, where the open-end of the tile 1 is clamped
CA 02572876 2007-01-04
WO 2006/005339 PCT/DK2005/000474
12
between the roof top 11 and the upper batten 20, and the first-end 14 has
been mounted to the lower batten 19 adjacent to the gutter 18. To enable
such an engagement between the roof top 11 and the gutter 18 it is preferred
that the roof top 11 comprises a system or a unit having an end part being
similar as said first-end so that the second-end 15 of the tile 1 can engage
with the roof top 11. The gutter 18 could just as well comprise a system or a
unit adapted to receive the first-end of the tile 1.
In general a roof element adapted to engage with a tile 1 having either a
first-
end or a second-end or even a combination of these can be used for
interconnecting with tiles. This roof element can as an example comprise
said roof top 11 and gutter 18, a frame work surrounding a window that is to
be built into a roof, a ridge, etc. In such a system the upper part of the
framework would preferably comprise a second-end to engage with the tiles
arranged above said upper part, and a first-end to engage with the tiles
arranged below said lower part.
Figure 8 shows a part of a sloping roof 80 with a plurality of tiles 27-29
mounted between parallel arranged battens 21, 22. Shown is an engagement
31, 32 between two tiles and the battens 21, 22. Preferably, the arrangement
of the tiles 27-29 is such that they overlap each other in two directions,
parallel and perpendicular to the battens 21, 22. This is of course to ensure
a
sufficient tightening on the roof. The mounting of the tiles 27-29 to the
battens 21, 22 may be done either by starting on the lowest row adjacent to
the gutter 24 and subsequently mount the second row of the tiles to the
second batten 22 and continue in an upward direction as indicated by the
arrow 38. The other way around is also possible, i.e. by starting on the
upmost raw and continue in a downward direction in the opposite direction to
the arrow 38.

The batten 25 which is perpendicular to said parallel battens 21, 22 is of
course necessary for the bearing capacity of the roof. When mounting the
tiles to the battens 21-24 at the crossings of said batten 25 and said battens
21, 22 the bendable flaps 6, as shown in Figs. 1 and 3, may either be bended
or removed, to form a gap in the engaging groove corresponding to the width
of batten 25. An example of this is depicted in Fig. 9 showing two flaps 41,
42
that have been bended upwards to enable a tile to engage with batten 22 at
e.g. the crossing between said batten 22 and the batten 25.
Figure 10 shows a perspective view of another embodiment of a tile 50,
which is to be used for covering surfaces such as a sloping roof or walls. The
tile 50 comprises a substantially flat plate 58 of length I 67 and width w 68
with a first-end 52 and a second-end 51, both which are extending along the
width 68 of the plate 58. As shown the second-end 51 comprises an inwardly
1s bend part along the width of the plate to form an engagement crook 57. The
first-end 52 comprises a back side plate 55 and a top-plate 53 that are,
respectively, substantially perpendicular and parallel to the plate 58 and a
nose part 56 that extends towards the second-end 51. Thereby a space is
created 70 adapted to engage with a batten. The nose part 56 is adapted to
engage with an engagement crook of a neighboring plate. This is illustrated
in Fig. 11 showing an engagement crook 59 of a neighboring plate that is to
be engaged with the nose part 56. Also shown in Fig. 11 is where the first-
end 52 has engaged with the batten 60 through a snap engagement. It is
obviously important that in order to allow such engagements the material of
the tile 50 has an elastic character and simultaneously high strength. An
example of material that could be used is any kind of metal such as
aluminum, copper or composite materials. Also, types of plastic materials or
the like are possible.
Figure 12 shows a part of a sloping roof 90 with a plurality of tiles 63-65 as
shown in Figs. 10-11 mounted between parallel arranged battens 61, 62.
CA 02572876 2007-01-04
WO 2006/005339 PCT/DK2005/000474

Shown is an engagement 71, 72 between two tiles and the battens 61, 62.
Preferably, the arrangement of the tiles e.g. 63-65 is such that they overlap
each other in two directions, parallel and perpendicular to the battens 61,
62.
This is of course to ensure a sufficient tightening on the roof. When mounting
the tiles it is possible to start at the upper most end by mounting the tiles
to
the batten 61 adjacent to the roof top and subsequently mount the second
row of the tiles to the neighboring batten 62 and continue in that way in an
downward direction as indicated by the arrow 67. The other way around
would also be possible. In order to enable the mounting of the tiles 63-65 at
the crossings between said tiles and the crossing batten 66 the back side
plate 55 first-end is cut into parallel strips (not shown) to form a plurality
of
bendable flaps (not shown). Thereby by bending or removing one or more
such flaps (similar as shown in Fig. 9) an engagement at the crossings is
possible.
Figure 13 shows another embodiment of a tile 100, comprising a central part
107 and a first-end 108 and a second-end 109, which both are adapted to
engage with two battens. The fastening elements 101, 102 of said ends
,extend substantially perpendicular upwards from said central part 107, and
along with the central part 17 define a slot (see Fig. 14) for engaging with
battens. While engaging the tile 100 with the battens the fastening elements
101, 102 are bend towards each other as indicated by the arrows 103, 104,
since the battens are forced between the outer sides of the fastening
elements 101, 102. Subsequently fastening elements 101, 102 are flipped
back into their initial position. Therefore, a snap engagement is obtained.
The
actual engagement between the tile 100 and two parallel battens is shown in
Fig. 14, showing where two parallel battens 105, 106 have engaged with the
tile 100. As shown, the battens are propped between the central part and an
outwardly extending part 100 of the fastening elements 101, 102.
