Wall boardings

Wall boardings having a series of wainscoting elements mounted in parallel and undercut at all edges. Strip-shaped lining mouldings are disposed both at the ends and between the wainscoting elements. The mouldings are overlapped along an adjacent undercut side edge of the wainscoting elements.

BACKGROUND OF THE INVENTION 
The present invention relates to wall boardings having a series of parallel 
wainscoting elements. 
Conventional wall panels place big demands on the skill of craftmanship. In 
addition, the mounting takes a long time resulting in lots of cut off ends 
and besides leaving behind dust and small bits of material which have to 
be cleared away. 
Panel sheets are also known which can be secured with fastening clips and 
which are adapted in advance to a particular ceiling height. Such plates 
are, however, difficult to adapt to varying ceiling heights. Besides, the 
bordering with such plates continues to be labor-demanding and difficult 
to perform. The most significant disadvantage with conventional panel 
sheets is, however, that the finishing around doors and windows is 
difficult to carry out and awkward to get to go together visibly with the 
wall surfaces. 
Ceiling facing is also known where sheets are fastened in a diamond pattern 
and where the joints are covered by borders which, if desired, can be 
undercut along the sides so that they engage over the sheet edges. The 
mounting of such borders involves, however, painstaking cutting into 
lengths and, if necessary, carving in addition. 
The main object of the present invention is to create boardings for walls 
where the elements can be made ready in advance and employed at different 
ceiling heights without labor- and skill-demanding adaptation during 
mounting. The mounting ought to be simple and the finished boarding ought 
to have an attractive appearance, independent of the skill of the 
carpenter, to the person who has carried out the work. 
It is also an objective to create boardings which do not leave behind 
specks of dust after mounting. 
SUMMARY OF THE INVENTION 
According to the present invention a wall boarding comprises a series of 
wainscoting elements mounted in parallel and undercut at all edges and 
strip-shaped lining mouldings disposed both at the ends and between said 
wainscoting elements, said mouldings being overlapped along an adjacent 
undercut side edge of said wainscoting elements. 
The lining mouldings can have different breadths. It has been found 
convenient for a horizontally disposed cover strip to overlap at its lower 
edge a strip-shaped lining moulding along the upper edge of the latter. 
Another strip-shaped lining moulding can be overlapped along its under 
edge by the upper edge of this cover strip. Preferably, the cover strip is 
undercut on at least one side thereof so as to permit a variation in the 
degree of overlapping between the strip and an adjacent lining moulding. 
By varying the overlapping, an mm accurate edge accommodation can thereby 
be effected at ceiling, windows and doors. This can be done in a rational 
manner with relatively simple equipment. Good utilisation of the materials 
is possible so that in the fabrication process unreasonable play or cut 
off ends do not occur either. 
The lining mouldings between the wainscoting elements are often plates with 
dimensions permitting wainscoting elements of reduced breadth to be used.

DESCRIPTION OF THE PREFERRED EMBODIMENTS 
The invention can best be understood by reference to the embodiments seen 
in FIGS. 1 through 6. I FIG. 1, there is shown a corner of a room with a 
floor 11, two walls 12 and 13 and panelled ceiling 14. The panelled 
ceiling can be designed independently of the walls but is preferably 
provided with a boarding as will be described below. In the wall 12, there 
is a window 15 and in the wall 13, a door opening 16 with a door 17. 
A basic element is a wainscoting element 18 which can be designed and 
secured as disclosed in Norwegian Patent Application No. 810,513 with 
fastening clips on horizontal fastening laths (not shown). For example, 
fastening clips can be used with a plate-shaped main portion which, on 
each side, has a wing which stands at right angles out from the main 
portion and which at the end is folded into a grip claw. The breadth of 
the wainscoting or boarding elements can vary. 
All edges of the wainscoting element 18 are drawn forwards to noses 19A,19B 
(see FIG. 5). In reality noses 19A,19B are formed due to an undercut 20,21 
being milled out along both side edges and an undercut 22 at both end 
edges. The undercut 20 along one of the side edges and the undercut 22 
along the end edges can have a dimension (breadth) in from the edge of 
about 10 mm while the undercut 21 along the other side edge has a 
significantly greater dimension, for example, 23 mm. 
At the under edge of the wall boarding in FIG. 1, there is disposed a 
skirting board 24 of smooth edged, thin material which fits into the 
undercut 22 at the lower end edge of the wainscoting elements 18. 
In FIGS. 2 and 6, there is illustrated how this boarding can be terminated 
at the upper edge of the wall. Here there are mounted two thin, 
smooth-edged borders called underlying or lining strips, a first 25 right 
up under the ceiling and the other 26 at the upper edge 19 of the 
wainscoting or boarding elements 18. These two lining strips 25 and 26 are 
connected to a cover strip or accommodating strip 27 with chamfered or 
profiled edges 28 and with undercutting along the side edges and the end 
edges which, in principle, correspond to undercuts on the wainscoting 
element 18. At the under edge, however, the undercut has such a large 
dimension, for example, 23 mm, that different overlapping can be obtained 
between the lining strip 25 and the strip 27. 
The mounting of this boarding occurs on placing in position the skirting 
board 24 and the horizontal fastening strips (not shown) for the mounting 
clips. Thereafter, there is placed at a corner a lining strip or 
underlying panel 29. Thus the wainscoting elements 18 are placed in 
position further out from this corner. Between the individual wainscoting 
elements, there is fixed an underlying panel or a lining strip 29 in the 
form of a thin, smooth-edged border. This is screwed securely to the 
supporting wainscoting element 18. 
In an alternative embodiment, the underlying panels or lining strips 29 can 
have a substantially larger breadth than shown in FIG. 2, while the 
wainscoting elements 18 can be narrower. In this instance, plates can be 
used as lining strips. After the wainscoting elements 18 are secured, the 
two lining strips 25 and 26 are located by nailing, the one thus entirely 
below the ceiling and the other below the undercut 22 along the upper end 
edges of the wainscoting elements. The nailing of the lining strips 25 and 
26 can be done concealedly. Finally, cover strip 27 is put in position. It 
is appropriately secured with nails or screws. On cutting into lengths, 
the ends are used which are preferably profiled in a manner corresponding 
to the side edges. 
With this system, the breadth of the wainscoting can be adapted accurately 
to the wall by using lining strips 29 or corresponding plates of different 
breadth between the wainscoting elements 18. It is appropriate to mount 
the lining strips 29 on the wainscoting elements in pairs, for example, by 
means of screws which are screwed in from the back side as indicated 
above. It will be understood that wainscoting elements can be used of 
varying breadth. 
The boarding can be adapted to the height of the ceiling, partly by 
choosing different breadths for the lining strips 25 and 26 and partly due 
to the variation in the overlapping between the cover strips 27 and the 
lower lining strips. Otherwise, it is possible to make the wainscoting 
elements 18 of different standard lengths. In principle, the wainscoting 
elements can be substantially shorter than the height of the ceiling and 
two or more such wainscoting elements can be mounted over each other. 
FIG. 3 illustrates how the boarding can be designed with a door 16. At the 
upper edge of the door, it is appropriate to place a sheet 30, for 
example, of plywood, which is cut so that it fits below the cover strip 27 
and down below a corresponding strip 31 which is placed above the door 
frame. This reduces the demands for accurate fitting and accurate cutting 
of the sheet 30 because the overlapping of the cover strips 31 can be 
varied as required. At the ends, the sheet 30 can be allowed to go in 
under the last wainscoting element 18 up to the door on each side or a 
vertical cover strip 34 can be used. In this way, there is achieved the 
facing of the area above the door with ready made parts in the style of 
the remaining wall boarding without transitions being shown other than the 
joint between the end of the strip 26 and the end edge of the sheet 30. 
This reduces the demands for skill of craftmanship. 
FIG. 4 illustrates how one can correspondingly face the area below a window 
15, a sheet 32 being used which is allowed to go entirely down to the 
floor. The upper edge of the sheet is covered by a cover strip 33 and 
which is secured to the window frame. The cover strip 33 is cross-cut if 
desired in the middle in order that the end will retain the shape they are 
given by the producer. 
In the embodiment illustrated in the drawings, a room is shown where the 
dimensions are substantially standardised. However, the wall boardings of 
the present invention can also be used in rooms with ceiling heights above 
and below normal height. This can occur partly due to the use of 
wainscoting elements having larger or smaller lengths as mentioned above 
or due to the width and the overlapping on the strips being variable. With 
especially large ceiling heights it can be appropriate to mount hollow 
profile mouldings under the ceiling. This can in fact occur above the 
lining strip 25 in FIG. 2 and in that manner without further adapting the 
boarding. 
In the corners, the cover strips 27 are allowed to terminate a short 
distance from each other. With this mitring becomes unnecessary, the ends 
of the cover strips 27 being able to be shaped in a manner corresponding 
to the sides. The openings in to the corner can then be filled out with 
sheets which correspond to the lining strips. 
Wall boardings of the present invention can be modified in different ways. 
There can be utilised narrow or broad wainscoting elements or 
correspondingly broad or narrow lining strips. For example, plate elements 
can be employed as underlying panels or lining strips.
