Description

FIXTURE FOR LAYING A JOINT-COVERING/THRESHOLD-
COVERING PROFILED ELEMENT AND KIT COMPRISING SUCH
FIXTURE
The present invention relates to a fixture for laying a joint-
covering/threshold-covering profiled element and a kit comprising such
fixture.
Nowadays, when laying floors, elongated threshold-covering profiled
elements are often used to conceal the perimetric space of a flooring surface
or to join, continuously and without steps, two adjacent flooring surfaces
that are located on two different levels, and to protect the edges thereof.
Among the various models of profiled elements are ones that in cross-
section have a central portion, below which there are protrusions that form
seats for coupling heads of optional anchoring blocks to be inserted between
the two flooring surfaces, and two lateral portions adapted to rest the
profiled element on the two adjacent floor surfaces, with interposition of a
specific adhesive.
A fixture that comprises anchoring blocks and adhesives is well
adapted to maintain the installation position of the profiled element where
the flooring surfaces are coplanar or have a maximum height difference of
14 mm.
Usually, for height differences of up to 10 mm, adhesives are used
exclusively, while greater height differences up to a maximum of 14 mm,
require anchoring blocks as well.
This solution therefore presents a non-negligible limit on the
maximum height difference that can be joined. In fact, for greater height
differences different profiled elements are needed, for example ones that, in
cross-section, have a horizontal portion and an inclined portion for resting
on the lower flooring surface.
The aim of the present invention is to provide a fixture for laying a
threshold-covering profiled element which is capable of improving the

known art in one or more of the above mentioned aspects.
Within this aim, an object of the invention is to provide a fixture that
makes it possible to use a same threshold-covering profiled element in
different situations of height differences, which can be applied easily and
stably.
Furthermore, another object of the present invention is to overcome
the drawbacks of the known art in an alternative manner to any existing
solutions.
Another object of the invention is to provide a profiled element that is
highly reliable, easy to implement and has a low cost.
This aim and these and other objects which will become better
apparent hereinafter are achieved by a fixture according to claim 1,
optionally provided with one or more of the characteristics of the dependent
claims.
Further characteristics and advantages of the invention will become
better apparent from the description of a preferred, but not exclusive,
embodiment of the fixture according to the invention, which is illustrated by
way of non-limiting example in the accompanying drawings wherein:
- Figure 1 shows the fixture according to the invention with a
threshold-covering profiled element;
- Figure 2 shows the fixture according to the invention during the
laying of a threshold-covering profiled element;
- Figure 3 shows the fixture according to the invention during the
laying of a threshold-covering profiled element.
With reference to the above figures, the fixture according to the
invention, generally designated by the reference numeral 10, comprises an
insert 11 to be arranged under a profiled element 14 (joint-
covering/threshold-covering) and which is substantially L-shaped in cross-
section, with a first portion 12 arranged parallel to the flooring surface and
a
second portion 13 arranged substantially vertically at the side of the
flooring

surface.
The insert is provided preferably by molding plastic material such as,
for example, polyethylene or polypropylene, it is substantially rigid, and its
length is comprised preferably between 3 mm and 500 mm.
The profiled element shown, usually made of metal, for example
aluminum, is designated with the reference numeral 14. It is elongated in
extension and has, in cross-section, a central portion 15, below which there
are protrusions 16 that determine the presence of a dovetail-shaped cavity,
and two lateral portions 17 slightly inclined downward at the ends.
The first portion 12 of the insert 11 has a part 18 that is shaped
complementarily to the lower face of a portion of the profiled element 15,
i.e. the central portion.
In particular, such complementarily-shaped part 18 of the first portion
12 presents a dovetail shape in relief, that is to be coupled by snap action,
or
by insertion, below the profiled element, at the central portion 15.
The coupling can be inverted, with the dovetail-shaped cavity on the
insert and the complementarily-shaped relief on the profiled element.
In the example shown in Figure 2, the profiled element 14 is laid so as
to conceal the perimetric space with a height difference with respect to the
base 19 of the flooring surface 20 equal to the height of the second portion
13.
The second portion 13 is preferably 4 mm high.
In the example shown in Figure 3, the height difference is greater and
it can be seen that the fixture 10 advantageously also comprises a block 21
for compensating the height, which is to be positioned vertically below the
second portion 13.
Such block 21 for compensating can have different heights, to be used
according to the height difference to be compensated, preferably for
example of 3 mm, 6 mm, 9 mm and 12 mm.
The insert 11 has a bevel 22 at the corner of the L-shaped section,

which allows the interposition of an adhesive layer 23 applied between it
and the profiled element 14.
The fixture 10 in fact advantageously also comprises adhesive layers
23 to be interposed between the lower surface of the profiled element 14 and
the insert 11 at the bevel 22 and also, in a conventional manner, between the
flooring surface and the profiled element 14.
Usually the profiled element 14 is sold already provided with
adhesive layers 23 applied below the lateral portions 17, close to the outer
edges of the profiled element 14. Such adhesive layers 23 consist preferably
of bi-adhesive strips, from which the outer film is removed at the time of
laying.
The fixture 10 also conveniently comprises connectors for joining two
contiguous profiled elements 14 and blocks for anchoring the profiled
element 14, to be installed below the central portion 15, with the head of the
block in the cavity defined by the protrusions 16.
The insert 11, the blocks 21, the adhesive layers 23, the connectors
and the blocks for anchoring can be provided by the manufacturer in a
single package with the threshold-covering profiled element. In particular, it
is convenient to provide multiple blocks 21 of different heights in order to
enable the operator to lay the profiled element when there are several
different height differences in the flooring surface.
The invention also relates to a kit 24 that comprises the fixture 10 and
also the profiled element 14, which is elongated in extension and has, in
cross-section, a central portion 15, below which there are protrusions 16 that
determine the presence of a dovetail-shaped cavity, and two lateral portions
17, as described previously.
Use of the fixture, according to the invention, is evident from the
foregoing description and explanation and, in particular, it is clear that the
fixture enables the operator to easily and stably lay the threshold-covering
profiled element even in the presence of height differences greater than 14

5
mm.
In practice it has been found that the invention fully achieves the
intended aim and objects by providing a fixture that makes it possible to
easily and stably lay a same threshold-covering profiled element in different
situations of height differences.
The invention, thus conceived, is susceptible of numerous
modifications and variations, all of which are within the scope of the
appended claims. Moreover, all the details may be substituted by other,
technically equivalent elements.
In practice the materials employed, provided they are compatible with
the specific use, and the contingent dimensions and shapes, may be any
according to requirements and to the state of the art.
