Device for fastening a baseboard to a wall
1. Field of the Invention
The invention relates to a device for fastening a baseboard to a wall having a
mounting
profile made of plastic, which forms a wall leg and a receptacle web for the
baseboard,
which is arranged offset transversely in relation to the wall leg and has
clamping ribs
extending in the web longitudinal direction.
2. Description of the Prior Art
For fastening baseboards for floors, providing a mounting profile made of
plastic is
known (EP 2 169 143 A2), which has a wall leg fastenable on the wall and a
receptacle
web for the baseboard, which is plugged onto the receptacle web, which is
offset away
from the wall in relation to the wall leg and is approximately parallel to the
wall. The
receptacle web engages in this case in a receptacle groove of the baseboard,
which is
fixed with the aid of clamping ribs provided on the receptacle web. Because a
nonlinear
course of the wall has to be expected, difficulties result when plugging the
baseboard
onto the receptacle web of the mounting profile. As a result, longer sections
of the
baseboards require a greater allowance in relation to the engagement of the
receptacle
web in the receptacle groove of the baseboard provided for this purpose in
case of a
nonlinear course of the wall, to be able to plug the baseboard onto the
mounting profile,
while with shorter sections of the baseboard, a sufficient clamp connection
between the
receptacle web and the baseboard is endangered by such an allowance.
In order that a secure clamp of the receptacle web of a mounting profile in
the
receptacle groove of the baseboard can be ensured, bending the receptacle web
into
the shape of a hairpin is additionally known (WO 02/066764 A2), so that the
two legs,
which are each provided on the outer side with clamping ribs, of the hairpin-
shaped
receptacle web spring apart. The legs, which are pressed apart from one
another under
a pre-tension upon insertion of the receptacle web into the receptacle groove
of the

CA 02955278 2017-01-12
2
baseboard, therefore cause a springy contact of the clamping ribs on the walls
of the
receptacle groove and thus a tolerance compensation. The plugging of longer
sections
of the baseboard in particular onto a springy spread-apart receptacle web is
in no way
facilitated in the case of nonlinear courses of the wall, however.
SUMMARY OF THE INVENTION
The invention is therefore based on the object of designing a fastening device
for
baseboards so that not only the plugging of the baseboard onto the mounting
profile,
which is fastened on the wall, is facilitated independently of the respective
length of the
baseboard section to be plugged on, but rather also a secure clamp connection,
which
is substantially independent of the respective section length of the
baseboard, can be
achieved between the mounting profile and the baseboard.
Proceeding from a device of the type described at the outset, the invention
achieves the
stated object in that the clamping ribs are coextruded with the mounting
profile from a
flexible plastic.
Because the clamping ribs are formed from a flexible plastic, when the
baseboard is
plugged onto the rigid receptacle web, they are pivoted via the walls of the
receptacle
groove of the baseboard in the plugging direction toward the receptacle web
with the
effect that they provide the clearance required for the engagement of the
receptacle
web in the receptacle groove of the baseboard to plug the baseboard onto the
receptacle web of the mounting profile in the case of a nonlinear course of
the wall. The
clamping ribs, which are pivoted in toward the receptacle web in the plugging
direction
as a result of their flexibility, which is sufficient for this purpose, press
in this case with a
friction lock against the wall of the receptacle groove of the baseboard as a
result of the
intrinsic elasticity, so that these clamping ribs have to be bent over in the
withdrawal
direction to withdraw the baseboard from the receptacle web of the mounting
profile,
which is accompanied by an increased deformation resistance and therefore
ensures a
secure hold of the baseboard on the mounting profile in spite of the flexible
clamping

3
ribs. This is true in particular if the unloaded receptacle web including the
flexible
clamping ribs has a thickness which exceeds the width of the receptacle groove
of
the baseboard. Because the mounting profile is manufactured from a
substantially
rigid plastic, the flexible clamping ribs can be produced in a comparatively
simple
manner jointly with the mounting profile by coextrusion.
As a result of the intrinsic elasticity of the clamping ribs, a pressure force
is exerted
via the clamping ribs on the walls of the receptacle groove of the baseboard.
This
pressure force can advantageously be utilized to hold the baseboard in contact
on
the wall if the clamping ribs made of the flexible plastic are provided on the
side of the
receptacle web facing toward the wall leg.
To increase the withdrawal resistance of the baseboard from the receptacle
web, the
clamping ribs can form clamping lips protruding transversely from the
receptacle web,
which have a width corresponding to at least twice the thickness, which
facilitates the
pivoting in of the clamping ribs toward the receptacle web upon insertion of
the
receptacle web into the receptacle groove of the baseboard, but makes the
withdrawal of the baseboard from the receptacle web more difficult as a result
of the
width of the clamping ribs.
According to some embodiments disclosed herein, there is provided a device for
fastening a baseboard to a wall comprising: a mounting profile made of
plastic, which
forms a wall leg, and an upwardly protruding receptacle web for the baseboard,
the
upwardly protruding receptable web is arranged offset transversely in relation
to the
wall leg for engaging in a downwardly open groove of the baseboard for
clamping
accommodation of the baseboard, the upwardly protruding receptacle web being
configured so that the baseboard with the downwardly open groove is pluggable
onto
the upwardly protruding receptacle web when the mounting profile is fastened
on the
wall, and clamping ribs extending in the web longitudinal direction, wherein
the
clamping ribs are coextruded from a flexible plastic with the mounting
profile, and

wherein the clamping ribs made of the flexible plastic are provided on a side
of the
receptacle web facing toward the wall leg.
BRIEF DESCRIPTION OF THE DRAWING
The subject matter of the invention is illustrated by way of example in the
drawing,
specifically a device according to the invention for fastening a baseboard to
a wall is
shown in a schematic cross section.
DESCRIPTION OF THE PREFERRED EMBODIMENT
The device according to the invention has an extruded mounting profile 1 made
of
plastic, which forms a wall leg 3 fastenable to a wall 2, which is provided at
longitudinal intervals with longitudinal holes 4 for fastening screws. The
wall leg 3
protrudes from a
Date Recue/Date Received 2022-04-01

CA 02955278 2017-01-12
4
bottom leg 5, which is connected via an intended breakpoint 6 to the wall leg
3 and can
be separated from the wall leg 3 if needed. On the side opposite to the bottom
leg 5, the
mounting profile 1 forms a receptacle web 7 for the baseboard 8 to be fastened
on the
wall 2, which has a receptacle groove 9 for the receptacle web 7 for this
purpose. The
receptacle web 7, which is offset away from the wall 2 in relation to the wall
leg 3 and
extends approximately in parallel to the wall 2 or to the wall leg 3, is
provided on the
side facing toward the wall leg 3 with clamping ribs 10 extending in the web
longitudinal
direction, which are formed in the exemplary embodiment as clamping lips
protruding
transversely in relation to the receptacle web 7. These lip-shaped clamping
ribs 10 are
produced from a flexible plastic, specifically by coextrusion with the
essentially rigid
mounting profile 1, so that the clamping ribs 10, which are formed from a
sufficiently
flexible plastic, can be pivoted in relation to the receptacle web 7.
When the baseboard 8 is plugged onto the receptacle web 7 of the mounting
profile 1,
which is fastened on the wall 2, the clamping ribs 10 are accordingly pivoted
by the
applied wall 11 of the receptacle groove 9 of the baseboard 8 toward the
receptacle
web 7, which is accompanied by a tolerance compensation, on the one hand, and
enables a substantial compensation to a nonlinear course of the wall, on the
other hand,
so that the baseboard 8 can be plugged in a comparatively simple manner onto
the
receptacle web 7. The clamping ribs 10, which press with a pre-tension against
the wall
11 of the receptacle groove 9 as a result of the intrinsic elasticity thereof,
ensure a good
hold of the baseboard 8 in spite of the flexibility thereof, because the
withdrawal
resistance of the baseboard 8 from the receptacle web 7 is substantially
greater in
comparison to the plugging resistance as a result of the clamping ribs 10,
which are
pivoted in toward the receptacle web 7 in the plugging direction. To withdraw
the
baseboard 8 from the receptacle web 7, the clamping ribs 10 have to be bent
over in the
opposite direction in the withdrawal direction toward the receptacle web 7,
which
requires overcoming a corresponding deformation resistance as a result of the
width of
the clamping ribs 10, which exceeds the distance of the groove wall 11 from
the
receptacle web 7.

In addition, the mounting profile 1 can be provided with a springy locking
tongue 12,
which latches with a hooked attachment into a catch receptacle 13 of the
baseboard 8
when the baseboard 8 is plugged onto the receptacle web 7 of the mounting
profile 1.
