[0001] The present invention relates to a lowered ceiling comprising a wall angle runner
comprising a first upright wing which extends in longitudinal direction of the wall
angle runner and comprises connection means taking the form of a hole for receiving
a screw, connecting of the wall angle runner to a wall, the wall angle runner being
connected to the wall by the connection means in such a way that the first upright
wing extends along the wall, the wall angle runner further comprising a first flange
supporting at least one ceiling tile, the first flange being connected to the first
upright wing and pointing away from the first upright wing, according to the preamble
of the first claim.
[0002] A lowered ceiling usually comprises a grid comprising a plurality of parallel spaced
frame members which are connected to each other by one or more cross runners. The
grid is provided for supporting ceiling tiles. Along the walls, surrounding the lowered
ceiling, usually a number of wall angle runners are mounted, which function to support
the frame members and cross runners. Each wall angle runner comprises an upright wing,
for connection to the surrounding wall, and a flange, for receiving the edges of the
frame members and cross runners. Examples of wall angle runners are for example described
in
AU-A-2493871 and
US-A-2964148. In
AU-A-2493871, openings are provided for providing flanges for securing runners to the wall angle
and for attaching the wall angle runner to the wall. In
US-A-2964148 openings are provided for providing springs bearing against edges of tiles supported
on the wall angle runner to hold them in contact with the next adjacent tiles.
[0003] A common known problem in relation to the installation of lowered ceilings is the
fact that the wings of the wall angle runners which run along the wall will follow
the surface of the wall to which they are fixed. However, wall surfaces in buildings
are rarely perfectly flat and certain tolerances are permitted. As a result, the walls
in buildings often have a waving wall surface. The connection of the upright wing
of the wall angle runner to such a waving wall surface results in a deformation of
the wall angle runner. A waving wall surface can in particular cause a deformation
of the flange of the wall angle runner that supports the edges of the frame members
and cross runners. This deformation may result in gaps between the edges of the flange
of the wall angle runner and the ceiling tiles which are placed on top of the flange.
These gaps are unwanted because they adversely influence the esthetic view of the
lowered ceiling.
[0004] The deformation of the horizontal flange of the wall angle runner is stronger for
thin gauge steel wall angle runners, compared to extruded aluminum wall angle runners.
However, those aluminum wall angle runners are not always accepted because they are
often too heavy from an aesthetic point of view and not fire rated compared to the
variant roll formed profile out of thin steel. The deformation of the horizontal flange
of the wall angle runner as a result of a waving wall surface also depends on the
shape of the wall angle runner. In W-shaped wall angle runners for example, the horizontal
flange deforms fewer compared to L-shaped wall angle runner, because the second upright
wing already compensates for the undulations to some extend.
[0005] A known solution to compensate for deviations of the wall surface is to first mount
wooden slats to the wall surface and then fix the upright wing of the wall angle runner
to the wooden slats. The bottom edge of the wooden slats is often painted in black
to obtain a floating effect of the lowered ceiling. The use of wooden slats in order
to compensate for undulations of the wall surface is very time consuming and is not
fire rated. As a result this solution is not always accepted.
[0006] It is therefore an object of the present invention to provide a lowered ceiling comprising
a wall angle runner which compensates for tensions in the wall angle runner, as a
result of undulations of the wall surface to which the wall angle runner is connected,
in a simplified way.
[0007] This is achieved according to the present invention with a lowered ceiling comprising
a wall angle runner showing the technical features of the characterizing part of the
first claim.
[0008] Thereto, the lowered ceiling according to the present invention is characterized
in that the first upright wing comprises at least one mainly C-shaped perforation
for forming a first part in the first upright wing which is displaceable with respect
to a remaining second part in the first upright wing. The at least one perforation
encloses the connection means and the connection means are located in the first part
of the first upright wing such that upon fixing the runner to the wall, said first
part of the first upright wing will be displaced with respect to the second part in
the first upright wing when encountering an undulation and will as such compensate
for undulations in the wall surface to which it is attached.
[0009] The at least one perforation in the first upright wing creates a first part which
can be displaced with respect to the remainder of the runner to compensate for undulations
in the wall surface. In fact, because the at least one perforation creates an area
in the first upright wing with less material, the material between the longitudinal
edges of the upright wing and the at least one perforation will be displaced with
respect to the remainder of the runner upon mounting of the wall angle runner to an
undulating wall surface, for example by screwing. The presence of a displaceable part
in the upright wing, reduces the risk and possibly eliminates the occurrence of tensions
in the wall angle runner. In particular the risk to the occurrence of tensions in
the flange of the wall angle runner which provide a supporting edge for the ceiling
tiles, is reduced. Thus, the risk to deformation of the first flange is reduced, a
better contact between and support by the first flange of the wall angle runner and
the ceiling tile placed on top of the first flange is provided, and the risk to the
occurrence of visible gaps between the first flange and the ceiling tile is minimised.
[0010] The use of a wall angle runner in the lowered ceiling according to the present invention
provides a number of additional advantages compared to the use of wooden slats. A
first advantage is that the wall angle runner in the lowered ceiling according to
the present invention is suitable for use in clean room situations and hospital environments.
Other advantages are that fire resistance can be guaranteed and that the assembling
is less time consuming. In fact, the positioning of these wall angle runners can be
done in one step only, whereas the use of wooden slats always requires minimum two
steps, namely the connection of the wooden slat to the wall and the connection of
the wall angle runner to the wooden slat. In most cases, even a third step is needed,
namely the painting black of the wooden slat to create an improved lowered ceiling
effect. Moreover, the application of this type of wall angle runner to the wall can
be done by one professional only, whereas the application of the wooden slats in most
cases requires two professionals with different expertise.
[0011] The first flange points away from the first upright wing. As a result, because first
upright wing extends in longitudinal direction of the wall after connection of the
wall angle to the wall, the first flange points away from the wall after connection
of the wall angle to the wall. The first flange may extend under any angle with respect
to the first upright wing or with respect to the wall. Preferably, the first flange
points away from the first upright wing in a direction perpendicular to the first
upright wing or in a direction perpendicular to the wall.
[0012] The at least one perforation is mainly C-shaped. A C-shaped perforation has the advantage
that a lip can be created in the first upright wing that is bendable with respect
to the first upright wing. This bendable lip can be used for a number of different
applications, besides its function as a displaceable member for mounting the wall
angle runner to the wall. The bendable lip can for instance be used as a connecting
tool for connection with a cross runner of a lowered ceiling or to connect a cross
direction profile to the wall angle runner. Moreover, the bendable lip allows the
connection between a cross runner or cross direction profile with a wall angle runner
to be done by one person only. The connection can be done by, in a first step, positioning
the cross runner or cross direction profile with its opposite end parts in cross direction
on top of the first flanges of facing wall angle runners. In a second step, the cross
runner or cross direction profile can be connected to the wall angle runner by bending
the flexible lips of the first upright flanges of said facing wall angle runner over
the upright web of the cross runner or cross direction profile and connecting it thereto.
[0013] The size, shape and number of perforations determine the capability of the wall angle
runner to compensate for tensions in the wall angle runner. The larger the at least
one perforation is, the larger is the first part which is displaceable with respect
to a remaining part of the first upright wing and the more the wall angle runner is
capable of compensating for undulations in the wall surface. The person skilled in
the art will be capable of adjusting the number, position and size of the perforations
to the profile of the wall to which the wall angle runner is to be mounted and the
envisaged stability of the runner. Preferably, the wall angle runner comprises a plurality
of perforations in longitudinal direction of the first upright wing. Such a wall angle
runner allows compensating for tensions along the whole wall surface and provides
and minimizes the risk to the occurrence of visible gaps between the first flange
and the lowered ceiling which is mounted on the wall angle runner. However, when applying
the at least one perforation in the first upright wing of the wall angle runner, one
should take into account that the first upright wing maintains sufficient strength
and bend resistance, to be able to hold the weight of the ceiling members which are
placed on top of the first flange of the wall angle runner.
[0014] The invention is further elucidated in the appending figures and description of the
figures.

for the lowered ceiling according to the present invention.

for the lowered ceiling according to the present invention wherein the fifth flange
extends in a direction perpendicular to the first upright wing.
Figure 7 shows a cross section of a third preferred embodiment of the wall angle runner
for the lowered ceiling according to the present invention wherein the fifth flange
extends in a slanted downward direction towards the first flange.
Figures 8A and 8B respectively show a cross section and 3-dimensional view of a fourth
preferred embodiment of the wall angle runner for the lowered ceiling according to
the present invention wherein the sixth flange extends in a slanted downward direction
away towards the first flange.
Figure 9 shows a cross section of a fourth preferred embodiment of the wall angle
runner for the lowered ceiling according to the present invention wherein the sixth
flange extends in a direction perpendicular to the first upright wing.
[0015] The wall angle runners 1, 11, 21, 31, 41 shown in figures 1-9, extend in longitudinal
direction of the wall and comprise a first upright wing 2 and a first flange 5, which
are connected to each other in longitudinal direction of the runner. The connection
may be direct, along mating longitudinal edges or indirect through one or more intervening
flanges.
[0016] The first upright wing 2 is provided for connecting the wall angle runner 1, 11,
21, 31, 41 to the wall. Thereto, the first upright wing 2 comprises connection means
10. The connection means 10 takes the form of a hole for receiving a screw as is shown
in figure 1. The first upright wing 2 comprises a top longitudinal edge 4 and a bottom
longitudinal edge 3. After connection of the wall angle runner to the wall, the first
upright wing extends in longitudinal direction of the wall. The first upright wing
can be a straight vertical wing, or may comprise bended part, as is shown for instance
in figures 8a, 8b and 9.
[0017] Preferably, the first upright wing 2 comprises a first hemmed edge 63, formed by
a part of its top longitudinal edge 4 which is folded downwards an inner face of the
first upright wing 2. This is for instance shown in figures 3A, 3B and 6. This first
hemmed edge 63 is mainly provided for aesthetic reasons. It is also provided for safety
reasons because the first hemmed edge 63 minimizes the risk for cutting wounds resulting
from the sharp edges of the wall angle runners during handling of the wall angle runners.
The hemmed edge can be bent so as to run along the face of the first upright wing
2 which faces the wall, but preferably is bent to run along the opposite face of the
first upright wing 2.
[0018] The first flange 5 is provided for supporting at least one ceiling member 8, such
as for example a ceiling tile or a frame member or cross runner of a lowered ceiling.
The first flange 5 is connected to the first upright wing 2 in such a way that, after
connecting the first upright wing 2 to the wall, the first flange 5 points away from
the wall. The first flange 5 may extend under any angle with respect to the first
upright wing 2 considered suitable by the person skilled in the art, but preferably
extends in a direction perpendicular to the first upright wing 2, and thus in a direction
perpendicular to the wall. The first flange 5 comprises a first longitudinal edge
6, proximal to the wall, and a second longitudinal edge 7, remote from the wall.
[0019] Preferably, the first flange 5 comprises a second hemmed edge 64, formed by a part
of the first flange 5 near its second longitudinal edge 7 which is folded upwards
onto a top face of the first flange. This is for instance shown in figures 1, 3A,
3B, 4, 5, 6, 8A, 8B and 9. This second hemmed 64 edge is mainly provided for aesthetic
reasons and assures that only a coated or painted part of the wall angle runner 1
is visible from beneath the lowered ceiling.
[0020] The first upright wing 2 further comprises at least one perforation 9. The at least
one perforation 9 forms a first part in the first upright wing 2 which is displaceable
with respect to a remaining second part in the first upright wing 2. Upon fixing the
runner to the wall, said first part in the first upright wing 2 will be displaced
with respect to a remainder of the first upright wing 2 when encountering an undulation
and will as such compensate for undulations in the wall surface to which it is attached.
Because of this ability to deform, tensions caused by the occurrence of irregularities
in the wall may be absorbed by deformation of the upright wing 2, in particular by
displacement of the first part. As tensions are absorbed within the first upright
wing 2, the risk to transferring of tension from the upright wing 2 to the first flange
5 and any ensuing deformation of flange 5, is strongly reduced. As a result, the risk
to deforming the support surface for the ceiling tiles is minimal, the contact between
the edge of the ceiling tiles mounted on top of the flange 5 is optimised and the
risk to the occurrence of visible gaps between the ceiling tile and the first flange
5 is minimal.
[0021] The position of the at least one perforation 9 on the upright wing 2 can be any position
considered suitable by the person skilled in the art. The at least one perforation
9 can be applied in a middle part of the first upright wing 2, or near the bottom
3 or top 4 longitudinal edge of the first upright wing 2. In case the at least one
perforation 9 is applied near the top longitudinal edge 4 of the first upright wing
2, the first upright wing 2 preferably does not comprise a first hemmed edge 63 as
this would reduce the ability of the wall angle runner 1 to compensate for undulations
in the wall surface. Thereby, the person skilled in the art will seek the optimum
compromise between optimal deformability of the upright wing and optimum strength,
stability and support force of the runner.
[0022] Some examples of different shapes and positions of the at least one perforation 9
are given in figures 2a - 2k. The at least one perforation 9 shown in figure 2a, which
is not covered by the claims, takes the form of one elongated recess applied below
the connection means 10. The at least one perforation 9 shown in figure 2b, which
is not covered by the claims, comprises two elongated recesses, one applied above
the connection means 10 and one applied below the connection means 10. The at least
one perforation 9 shown in figure 2c, which is not covered by the claims, comprises
two protruding bended parts, one at each side of the connection means 10. The at least
one perforation 9 shown in figures 2d-2g comprises two C-shaped recesses. Each of
the C-shaped recesses is located such that it encloses the connection means 10. The
orientation of the C-shaped recesses with respect to the longitudinal edges 3, 4 of
the first upright wing and the orientation of the C-shaped recesses with respect to
each other may vary as is shown in figures 2d-2g. The at least one perforation 9 shown
in figures 2h and 2i comprises a first and a second elongated recess which extend
under an angle with respect to each other. The at least one perforation 9 shown in
figure 2j comprises a circular shaped recess. The at least one perforation 9 shown
in figure 2k, which is not covered by the claims, comprises a star shaped recess.
[0023] Preferably, the at least one perforation 9 is C-shaped as is shown in figures 2d-2g.
A C-shaped perforation comprises three elongated recesses which together form a letter
C. A C-shaped perforation has the advantage that within the rectangle defined by said
three elongated recesses a lip can be created that is bendable with respect to the
first upright wing 2 as is shown in figures 3a and 3b. The lip can be formed by the
whole rectangle defined by said three elongated recesses as is shown in figure 3a
or by only part of the rectangle as is shown in figure 3b. The orientation of said
bendable lip may vary depending for instance on the orientation of said C-shaped perforation
and on the amount of bending of the lip. The bendable lip may for instance point away
from the first upright wing 2 to extend in a direction perpendicular to the first
upright wing 2 as is shown in figure 3a. This orientation of the bendable lip is in
particular suitable for mounting and connecting a cross runner of a lowered ceiling
to the wall angle runner 1 as is shown in figure 3a. The cross runner of the lowered
ceiling shown in figure 3a rests with its horizontal flange on the first flange 5
of the wall angle runner 1 and is connected with its upright web to the flexible lip
of the first upright wing 2 of the wall angle runner 1, 11, 21, 31, 41. However, any
other position of the bendable lip with respect to the first upright wing 2 is considered
suitable by the person skilled in the art. In order to facilitate the connection of
the flexible lip to a ceiling member 8, such as a cross runner, the flexible lip preferably
comprises a mounting member. The mounting member of the bendable lip as shown in figure
3a may for instance comprise a hole for receiving a screw which can be screwed in
the upright web of the cross runner. However, the mounting member can have any other
form considered suitable by the person skilled in the art. In figure 3b the bendable
lip of the wall angle runner is used as a hold down member to avoid deformation of
thin ceiling tiles.
[0024] The connection means 10 for connecting the wall angle runner 1, 11, 21, 31, 41 to
the wall can take any position considered suitable by the person skilled in the art
with respect to the at least one perforation 9 so that the perforation 9 enclosed
the connection means 10. The position of the connection means 10 is such that it is
located in the first part of the first upright wing 2 which is displaceable with respect
to a remaining second part in the first upright wing 2.
[0025] The size, shape and number of perforations can be adjusted by the person skilled
in the art taking into consideration the amount of unevenness of the wall. Preferably,
the wall angle runner comprises a plurality of perforations in longitudinal direction
of the first upright wing 2 as is shown in figures 2a-2k, allowing compensating for
tensions along the whole length of the wall angle runner 1, 11, 21, 31, 41.
[0026] The perforations can be applied during or after production of the wall angle runner
1, 11, 21, 31, 41, for instance at the construction site itself. The position, size
and number of the perforations 9 can be adjusted to the position of the undulations
in the wall surface and to the amount of unevenness of the wall surface. Preferably,
the distance between subsequent perforations 9 is fixed. This allows the perforations
9 to be applied during production of the wall angle runner 1, 11, 21, 31, 41. This
can for instance be achieved with a rotating press roll which rotates at substantially
the same rate as the rate at which the wall angle runner 1, 11, 21, 31, 41 is produced,
such that the perforations 9 can be formed at the same time and same rate as the wall
angle runner 1, 11, 21, 31, 41 itself.
[0027] The at least one perforation 9 can be applied in the first upright wing 2 of any
type of wall angle runner 1, 11, 21, 31, 41 considered suitable by the person skilled
in the art.
[0028] A simple embodiment of a wall angle runner 1 although not covered by the claims is
shown in figure 1. The first flange 5 is directly connected with its first longitudinal
edge 6 to the bottom longitudinal edge 3 of the first upright wing 2 in such a way
that an L-shaped wall angle runner is created. The first upright wing 2 of the wall
angle runner 1 shown in figure 1 comprises at least one perforation 9 in the form
of one elongated recess located beneath the connection means 10. The at least one
perforation 9 may however have any other shape considered suitable by the person skilled
in the art. Upon connection of the first upright wing 2 to the wall, the part between
the elongated recess 9 and the bottom longitudinal edge 3 of the first upright wing
2 will be displaceable with respect to a remainder of the first upright wing 2 when
encountering an undulated wall surface and will minimize the risk to creating tension
at the first flange 5.
[0029] A preferred embodiment of the wall angle runner 11 for the lowered ceiling according
to the present invention is shown in figure 4. The wall angle runner 11 comprises
a first 5 and a second 15 flange and a first upright wing 2. The first 5 and the second
flange 15 are connected with their first longitudinal edges 6, 16 to respectively
the bottom 3 and top 4 longitudinal edge of the first upright wing 2 in such a way
that a C-shaped wall angle runner is created. The first 5 and the second 15 flange
may extend under any angle with respect to each other, but preferably run parallel.
More preferably the first 5 and second 15 flanges both extend perpendicular with respect
to the first upright wing 2. The first upright wing 2 of the wall angle runner comprises
at least one perforation (not shown) 9 for forming a part in the first upright wing
2 which will be displaceable with respect to a remainder of the first upright wing
2 upon connection of the wall angle runner to an undulating wall surface to compensate
to a certain extend for undulations in the wall surface. The at least one perforation
9 has a C-shape, allowing for instance the connection of cross profiles in wall-to-wall
applications in a simplified way. Moreover, the C-shape of the wall angle runner allows
the cross runner to be clamped between the first and the second flanges of the wall
angle runner, which provides for an improved positioning of the cross profile with
respect to the wall angle runner. Another advantage of the C-shaped wall angle runner
is that it results in a further reduction of tensions in the first flange compared
to the L-shaped wall angle runner of figure 1 because part of the tension is transferred
to and absorbed by the second flange of the wall angle runner. As a result, a C-shaped
wall angle runner 11 provides for an improved resistance against deformation of the
first flange 5 of the wall angle runner as a result of an undulated wall surface as
compared to an L-shaped wall angle runner 1.
[0030] A second preferred embodiment of the wall angle runner 21 for the lowered ceiling
according to the present invention is shown in figure 5. The wall angle runner 21
comprises a first wall angle runner part 28 and a second wall angle runner part 29
which are removably connected to each other. The first wall angle runner part 28 comprises
a first upright wing 2 and a third flange 25. The third flange 25 is with its first
longitudinal edge 26 directly connected to the bottom longitudinal edge 3 of the first
upright wing 2, in such a way that the first wall angle runner part 28 forms an L-shaped
wall angle runner part. The first upright wing 2 and the third flange 25 may extend
under any angle with respect to each other, but preferably extend perpendicular with
respect to each other. The second wall angle runner part 29 comprises a first flange
5, a fourth flange 35 and a second upright wing 12 which are connected to each other
in such a way that a C-shaped wall angle runner part is formed. Thereto, the first
flange 5 is with its first longitudinal edge 6 directly connected to the bottom longitudinal
edge 13 of the second upright wing 12 and the fourth flange 35 is with its first longitudinal
edge 36 directly connected to the top longitudinal edge 14 of the second upright wing
12. The first 5 and the fourth flange 35 may extend under any angle with respect to
each other, but preferably run parallel. More preferably the first 5 and fourth flanges
35 both extend perpendicular with respect to the first upright wing 2. The second
longitudinal edge 37 of the fourth flange 35 is folded away from the first flange
5 onto an outer face of the fourth horizontal flange 35 in such a way that a third
hemmed edge 65 is formed. The first wall angle runner part 28 and the second wall
angle runner part 29 are connected such that the third flange 25 is being received
between the third hemmed edge 65. This 2-part wall angle runner 21 has a number of
advantages. First, the wall angle runner 21 shown in figure 5 results in a further
reduction of tensions in the first flange 5 of the wall angle runner compared to the
L-shaped wall angle 1 runner of figure 1 and compared to the C-shaped wall angle runner
11 of figure 4. This results from the fact that, because the first wall angle runner
part 28 and the second wall angle runner part 29 are removably connected and do not
form one single piece, a deformation of the first wall angle runner part 28 is not
or only to a minor extend transferred to the second wall angle runner part 29, and
thus to the first flange 5. The wall angle runner 21 thus comprises two places where
tensions are compensated: 1) the first upright wing 2 of the first wall angle runner
part 28 which comprises at least one perforation 9 and 2) the connection between the
first 28 and the second 29 wall angle runner part which minimizes transfer of deformation
of the third flange 25 to the first flange 5. A second advantage of the wall angle
runner 21 shown in figure 5 is that it allows creating a floating effect of the lowered
ceiling in a simplified way. Thereto, the width of the third flange 25 is preferably
smaller than the width of the fourth flange 35, such that, after connection of the
first wall angle runner part 28 to the second wall angle runner part 29, only part
of the third flange 25 of the first wall angle runner part 28 is covered by the fourth
flange 35 of the second wall angle runner part 29. This uncovered part of the third
flange results in a shadow-effect, which gives a floating effect to the lowered ceiling
when mounted to the wall angle runner 21. It also allows obtaining a similar effect
as the one obtained by black wooden slats in a much more simplified way. In fact this
effect can be obtained in a number of different ways. Because the wall angle runner
comprises two separate wall angle runner parts, these parts can be produced separately
and can be made in different colours suited for their use. By providing the first
wall angle runner part 28 in a first dark colour, for instance in black, and the second
wall angle runner part 29 in a similar colour of the ceiling, a similar effect as
the one obtained with black wooden slats can be obtained. Another way to obtain a
similar effect as the one obtained with black wooden slats, is to apply in the space
between the wall and the second upright wing a dark sealing block. This sealing block
can be made from an acoustic absorbing material or even from a material which expands
during fire. Moreover, this sealing block can be applied during production of the
wall angle runner in the form of a self adhesive strip onto the bottom of the first
flange, such that the wall angle runner can be made by one manufacturer only. A third
advantage of the wall angle runner shown in figure 5 is that the uncovered part of
the third flange of the first wall angle runner part can be used for different purposes.
The uncovered part can for instance comprise one or more recesses. These recesses
can provide for ventilation through the wall angle runner and avoid super heating
of the plenum above the lowered ceiling. The uncovered part can also be used to connect
devices which are preferably invisible for the eye, for instance for connection of
lighting.
[0031] A third preferred embodiment of the wall angle runner 31 is shown in figures 6 and
7. The wall angle runner 31 is a one-piece wall angle runner comprising a first upright
wing 2, a fifth flange 45, a third upright wing 22 and a first flange 5. The wall
angle runner 31 is connected to the wall with its first upright wing 2. The first
upright wing 2 comprises at least one perforation 9 for compensating for undulations
in the wall surface. The fifth flange 45 is with its first longitudinal edge 46 connected
to a bottom longitudinal edge 3 of the first upright wing 2 and with its second longitudinal
edge 47 connected to a top longitudinal edge 24 of the third upright wing 22. The
third upright wing 22 points downwardly away from the fifth flange 45. The third upright
wing 22 may extend under any angle with respect to the first upright wing 2 but preferably
extends parallel to the first upright wing 2. The first flange 5, which is provided
for receiving the ceiling members, is with the first longitudinal edge 6 connected
to the bottom longitudinal edge 26 of the third upright wing 22 and points away from
the first upright wing 2. The fifth flange 45 points away from the first upright wing
2. Any orientation of the fifth flange 45 with respect to the first upright wing 2
considered suitable by the person skilled in the art is possible. Figure 6 shows a
wall angle runner 31 in which the fifth flange 45 points away from the first upright
wing 2 in a direction perpendicular to the first upright wing 2. Figure 7 shows a
wall angle runner 31 in which the fifth flange 45 points away from the first upright
wing 2 in a downward slanted direction towards the first flange 5.
[0032] The wall angle runner 31 shown in figure 6 has a similar W-shape as the one of figure
5, with the difference that the wall angle runner 31 as shown in figure 6 is a one-part
wall angle runner, as compared to the 2-part wall angle runner 21 shown in figure
5. The wall angle runner 31 shown in figure 6 has similar advantages as the wall angle
runner 21 shown in figure 5. First, the wall angle runner 31 shown in figure 6 results
in a further reduction of tensions in the first flange 5 of the wall angle runner
31 compared to the L-shaped wall angle runner 1 of figure 1. This reduction is due
to the fact of the 3-angle absorption of the tensions: the angle between the first
upright wing 2 and the fifth flange 45, the angle between the fifth flange 45 and
the third upright wing 22 and the angle between the first flange 5 and the third upright
wing 22 each absorb part of the created tension and avoid transfer of the tension
to the first flange 5 of the wall angle runner. Second, the fifth flange 45 also gives
a shadow-effect to the wall angle runner 31, which gives a floating effect to the
lowered ceiling when mounted to the wall. This floating effect can be enhanced by
for instance applying a sealing block in the space between the wall and the third
upright wing 22 as is shown in figure 6. A third advantage of the wall angle runner
shown in figure 6 is that the fifth flange 45 can comprise ventilation holes or comprise
lighting members.
[0033] Similar to the wall angle runner 31 shown in figure 6, the wall angle runner 31 shown
in figure 7 provides in a reduction of tension in the first flange 5 of the wall angle
runner compared to the L-shaped wall angle runner 1 of figure 1, allows the presence
of ventilation holes or lighting members in the fifth flange 45 and gives a certain
floating effect to the lowered ceiling.
[0034] A fourth preferred embodiment of the wall angle runner 41 for the lowered ceiling
according to the present invention is shown in figures 8 and 9. The wall angle runner
41 shown in figures 8 and 9 comprises a first upright wing 2 which is hidden behind
and connected to a fourth upright wing 32 by an intervening sixth flange 55. The wall
angle runner further comprises a first flange 5. The wall angle runner 41 is connected
to the wall with its first upright wing 2. The first upright wing 2 comprises at least
one perforation 9 for compensating for undulations in the wall surface. The sixth
flange 55 is connected to a top longitudinal edge 4 of the first upright wing 2 with
its first longitudinal edge 56 and to a top longitudinal edge 34 of the fourth upright
wing 32 with its second longitudinal edge 7. The fourth upright wing 32 may extend
under any angle with respect to the first upright wing 2 and with respect to the sixth
flange 55, but preferably extends parallel to the first upright wing 2 and downward
from the sixth flange 55. The first flange 5, which is provided for supporting the
ceiling members, is with a first longitudinal edge 6 connected to the bottom longitudinal
edge 33 of the fourth upright wing 32 and points away from the first upright wing
2, preferably in a direction perpendicular to the first upright wing 2. The sixth
flange 55 points away from the first upright wing 2. Any orientation of the sixth
flange 55 with respect to the first upright wing 2 considered suitable by the person
skilled in the art is possible. Figure 8 shows a wall angle runner 41 in which the
sixth flange 55 points away from the first upright wing 2 in a downward slanted direction
towards from the first flange 5. Figure 9 shows a wall angle runner 41 in which the
sixth flange 55 points away from the first upright wing 2 in a direction perpendicular
to the first upright wing 2.
[0035] Similar to the wall angle runner 31 shown in figures 6 and 7, the wall angle runner
41 shown in figures 8 and 9 provides in a further improved reduction of tension in
the first flange 5 of the wall angle runner compared to the L-shaped wall angle runner
1 because part of the tension is absorbed by the sixth flange 55 and not transferred
to the first flange 5. This type of wall angle runners also allows the presence of
ventilation holes or lighting members in the sixth flange 55 and gives a certain floating
effect to the lowered ceiling. The ventilation holes in the sixth flange 55 form an
additional part which is displaceable with respect to the rest of the wall angle runner
and allows for additional compensation of tensions in the wall angle runner.
[0036] Preferably, the bottom longitudinal edge 3 of the first upright wing 2 of the wall
angle runner 41 is folded in such a way that a first suspension hook 61 is formed.
The first suspension hook 61 may point away from the wall as is shown in figure 8
or may point towards the wall as is shown in figure 9. The first suspension hook 61
may be used for any purpose considered suitable by the person skilled in the art.
It can for instance by used as an invisible suspension member that can be used to
hang on a painting or frame to the wall. This is achieved by folding a part of a bottom
longitudinal edge 3 of the first upright wing 2 in a slanted upward direction, in
a direction which points away from the first flange 5 or in other words towards the
wall. In the example shown in figure 9 the suspension hook is achieved by folding
an end part of the wing 2, however any other method for providing a suspension hook
may be used as well.
[0037] Preferably, the first flange 5 of the wall angle runners 21, 31, 41 for the lowered
ceiling according to the present invention which comprise a space between the first
upright wing 2 and another upright wing 12, 22, 32, i.e. a second, third or fourth
upright wing, comprise a second suspension hook 62. The second suspension hook 62
comprising a part of the first longitudinal edge 6 of the first flange 5 which is
folded in a slanted direction towards the wall, i.e. a direction pointing away from
the first flange 5, and back towards the first flange 5, in such a way that a second
suspension hook 62 is formed. Usually both parts of the suspension hook run along
each other. Although in this embodiment the suspension hook is formed by folding of
a part of the first flange, any other way of forming a suspension hook may be used
as well. The above described suspension hook is for instance shown in figure 7. This
second suspension hook 62 further reduces the risk to the occurrence of tensions in
the first flange. This suspension hook 62 also has the advantage that it provides
in an invisible suspension member that can for instance be used to hang on a painting
or frame to the wall. This type of suspension hook may also be used for mounting a
capping material to the visible bottom face of the first flange. The capping material
may fore example take the shape of a C-shaped cap and can be applied by simply hooking
the capping material behind the wall angle runner. This allows the wall angle runner
to be produced in an uncoated material, and to provide only that part of the wall
angle runner which is visible to the eye with coloured capping material.
