Finishing device for a floor
1. Field of the invention
The invention relates to a finishing device for a floor, with a finishing
strip and a
holder forming a wall leg, which holder has a holding web, which protrudes
upwardly parallel to the wall leg and engages in a downwardly open receiving
groove of the finishing strip, for receiving the finishing strip in a clamped
manner.
In order to secure finishing strips for floors, it is known (EP 2 169 143 A2)
to
provide a holder which has a wall leg that can be secured to the wall and a
holding
web for the finishing strip, which is fitted on the wall-parallel holding web
offset
away from the wall relative to the wall leg. Here, the holding web engages in
a
downwardly open, likewise wall-parallel receiving groove of the finishing
strip,
which is held down with the aid of clamping fins provided on the holding web.
The
finishing strip is therefore fitted wall-parallel on the holder, which means
that the
finishing strip can be lifted from the wall by relatively low forces.
If, in another known finishing device (WO 02/066764 A2), the downwardly open
receiving groove has a central axis in cross-section that is inclined away
from the
wall, this receiving groove for the holding web of the holder defines the
direction in
which the finishing strip is fitted on the holding web, with the effect that,
as the
finishing strip is fitted on the holder secured to the wall, the finishing
strip is
pressed against the wall. In order to ensure that the finishing strip bears in
a
sustained manner against the wall, it must firstly be ensured that the holding
web
is received in the receiving groove with intensified clamping, which is
achieved by
a hairpin-like design of the holding web in conjunction with a detent
toothing. In
spite of the resultant, relatively complex construction, the finishing strip
must

CA 02991648 2018-01-08
2
additionally be latched to a floor leg of the holder in order to prevent the
finishing
strip from lifting off from the floor leg of the holder or from the wall.
SUMMARY OF THE INVENTION
The object of the invention is therefore to design a finishing device for a
floor so
that a reinforced bearing of the finishing strip against the wall can be
ensured
using means of simple design.
Proceeding from a finishing device of the type described in the introduction,
the
invention solves the stated problem in that the receiving groove in cross-
section
has a central axis inclined away from the wall leg.
As a result of this measure, as the finishing strip is fitted on the holder,
the holding
web of the holder engaging in the receiving groove of the finishing strip is
forcibly
bent away from the wall leg on account of the inclination of the receiving
groove
and is pretensioned, which results in a corresponding pressing force on the
finishing strip transversely to the wall. As a result, not only is the long-
term bearing
of the finishing strip against the wall improved, but also the clamped hold of
the
holding web in the receiving groove of the finishing strip on account of the
increase
of the clamping forces caused by the pretensioning is intensified. Due to the
pretensioning of the holding web, the strength of the holder is increased,
whereby
the hold of the finishing strip against the wall is also supported.
The inclination of the receiving groove relative to the wall leg of the holder
on the
one hand is intended to ensure a sufficient resilient pretensioning of the
holding
web, but on the other hand should not unnecessarily hinder the fitting of the
finishing strip on the holder. For this reason, the central axis of a cross-
section of
the receiving groove can enclose an angle between 7 and 15 , preferably
between 9 and 12 , together with the wall leg of the holder. With a receiving
groove in a range of inclination of this kind, the different requirements can
be met
advantageously
BRIEF DESCRIPTION OF THE DRAWING

CA 02991648 2018-01-08
3
The subject matter of the invention is illustrated in an exemplary manner in
the
drawing, and more specifically a finishing device for a floor according to the
invention is shown in a schematic cross-section.
DESCRIPTION OF THE PREFERRED EMBODIMENT
The finishing device for a floor 1 according to the invention comprises a
holder 2
for a finishing strip 3, which is held down both on the floor 1 and on the
wall 4 with
the aid of the plastic holder 2, which can be secured to a wall 4. The holder
2
forms a floor leg 5 supported on the floor 1 and a wall leg 6, which protrudes
from
the floor leg 5 and which is provided with slot-like through-holes 7 so as to
be
securely screwed to the wall 4. The wall leg 6 carries a holding web 8, which
engages in a downwardly open receiving groove 9 of the finishing strip 3 and
has
clamping fins 10, preferably made of a softer plastic. The receiving groove 9
is
oriented so that the central axis 11 of its cross-section runs at an incline
relative to
the wall leg 6 of the holder 2 and together therewith preferably encloses an
angle
a between 9 and 12 .
The holding web 8, which can be bent out resiliently at least to the extent of
the
angle of inclination a, in the unloaded state runs parallel to the wall leg 6
of the
holder 2 and together with the receiving groove 9 of the finishing strip 3
thus
likewise encloses the angle of inclination a, as indicated in the drawing by
means
of a dot-dash line. If the finishing strip 3, in order to be secured, is slid
onto the
holding web 8 of the holder 2 secured to the wall 4, the holding web 8
engaging in
the receiving groove 9 of the finishing strip 3 is bent away from the wall leg
6 as a
result of the design specifications and is pretensioned, thus causing a
pressing
force on the finishing strip 3 in the direction of the wall 4, so that, as the
finishing
strip 3 is slid onto the holding web 8, the finishing strip 3 is held pressed
against
the wall 4 under a corresponding pretension. In addition, due to the
engagement of
the holding web 8 in the receiving groove 9 of the finishing strip 3 under
pretension, said holding web is clamped in the receiving groove 9 in an
intensified
manner, and therefore the holder 2 is braced on account of the pretensioning
of
the holding web 8 and its guidance in the receiving groove 9.

In the extension of the holding web 8, the holder 2 forms a securing tongue 12
with
a securing stop 13, which engages behind a counter stop, formed by a
longitudinal
groove 14 in the finishing strip 3, when the finishing strip 3 rests on the
floor 1 in
the secured position. An unintentional removal of the finishing strip 3 from
the
holder 2 is additionally prevented by means of this securing stop 13.
