MODULAR HOOKING DEVICE FOR A CLOTH
FOR A TENSIONED FALSE CEILING
TECHNICAL FIELD OF THE INVENTION
The invention relates to the technical field of
tensioned false ceilings and false walls.
The invention relates more particularly to a
device for attaching at least one cloth for producing a
tensioned-cloth false partition.
PRIOR ART
Conventionally, false partitions are produced
from profiled members, normally referred to as rails,
able to be fixed to a wall or ceiling of a room, on
which flexible cloths are attached.
CA 02942201 2016-09-09

To enable them to be attached to the rails, the
cloths have peripheral edges provided with attachment
means conventionally in the form of a harpoon. The
associated rails for their part have a shape suitable
for holding the attachment means of said cloths. In
particular, they comprise a U-shaped groove comprising
an attachment shoulder on which the attachment means is
intended to bear. The cloths provided with attachment
means are in general PVC cloths.
Considering that, in the context of some
implementations or of the material from which the cloth
is produced, attachment by means of attachment means
such as a harpoon is not suitable, rails are proposed
in the form of flexible clips, said clips being
arranged to hold the cloth by gripping between two
flanges or wedging between a flange and a wall. The
cloths concerned then have no attachment means. Such
rails are frequently used with textile cloths.
The drawback of the rails described above is
that they are configured to suit only one type of
cloth. Type of cloth means cloths provided with
attachment means and cloths with no attachment means.
Thus the choice of a cloth depends on the type of rail
used and vice versa, which has several drawbacks. In
particular, when a cloth of an existing false partition
is replaced, the choice of the cloth will depend on the
rails initially used. Likewise, the rails, when they
are configured to receive several cloths, do not make
it possible to offer a mixture in the cloths used.

The invention aims to remedy these problems by
proposing a modular attachment device for attaching
either a cloth provided with attachment means or a
cloth with no attachment means.
The invention aims to propose also an attachment
device making it possible to adapt, simply and rapidly,
temporarily or not, an existing rail profile configured
for attaching a cloth with no attachment means.
The invention aims also to propose an attachment
device for providing the attachment of a plurality of
cloths, whether or not they are provided with
attachment means.
SUBJECT MATTER OF THE INVENTION
To this end, the invention proposes a device for
attaching at least one fabric for producing a
tensioned-cloth false partition comprising two profiled
members that can be fitted one in the other reversibly,
one of the profiled members forming a profiled rail
arranged so as to allow the attachment of a cloth
provided with attachment means, the other profiled
member comprising means for holding by clamping a cloth
with no attachment means when it is in place in the
profiled rail, said profiled members comprising mutual
holding means.
According to a particular aspect, the invention
proposes a device for attaching at least one cloth for
producing a tensioned-cloth false partition comprising
CA 02942201 2016-09-09
4
a first profiled member forming a profiled rail
configured so as to allow the attachment of a cloth
provided with attachment means and comprising at least
one reception groove, advantageously able to hold a
peripheral edge of a cloth equipped with an attachment
means, said groove being delimited by at least two
lateral walls, and at least one second profiled member,
able to be fitted removably in the reception groove of
the first profiled member, having a cross section in
the form of a U or V, one of the arms of the U or V
shape comprising at least one deformable longitudinal
projection arranged so as to come into abutment against
a wall disposed opposite the arm carrying the
deformable projection and thus, by clamping on said
wall, hold a cloth with no attachment means when the
second profiled member is in place in the reception
groove on the first profiled member (so as to hold the
cloth by clamping against the wall portion of the
reception groove, one of the arms of the U or V shape
further comprising a longitudinal slot sized so as to
house a shoulder formed on one of the lateral walls of
the reception groove.
Thus, when an existing false ceiling has been
produced by means of a cloth equipped with attachment
means and rails suitable for holding the attachment
means of the cloth (rails corresponding to the
aforementioned first profiled member), it is possible
to adapt said rails by inserting a profiled member of
the same type as the second profiled member so as to
CA 02942201 2016-09-09
allow the holding of a cloth with no attachment means.
This device therefore makes it possible to make certain
existing profiled members usable either in PVC
tensioned ceilings or ones made from Artolis0 textile
5 cloth.
Furthermore, the shoulder that makes it possible
to hold the second profiled member in the first also
constitutes the means for holding the attachment means
(of the harpoon type) equipping the peripheral edge of
the cloth. Because of this, the use of the second
profiled member requires no modification of the groove
or even providing in the groove a supplementary means
for attaching the second profiled member.
Moreover, the means for attaching the additional
profiled member on the profiled rail used, formed by
the longitudinal slot and the shoulder, makes it
possible to provide the holding of the additional
profiled member in the profiled rail, despite the
tension force exerted by cloth when it is fixed to the
additional profiled member.
Advantageously, the second profiled member has a
shape complementary to that of the reception groove of
the first profiled member.
Advantageously, the shoulder is arranged to
allow the attachment of the cloth provided with
attachment means.
CA 02942201 2016-09-09

Advantageously, the projection extends
substantially as far as a plane passing through the
internal face of the other arm of the U or V shape
opposite to the arm carrying the deformable projection.
This also makes it possible to wedge the cloth between
the deformable projection and the lateral partition
concerned. In a particular environment, the arm
opposite to the one carrying the projection constitutes
the partition against which the projection comes into
abutment.
Advantageously, the deformable projection
extends beyond a plane corresponding to the external
face of the arm opposite to the arm carrying the
deformable projection.
Advantageously, the other arm has a partition
portion forming an entry ramp.
Advantageously, the deformable projection has a
flange profile.
Advantageously, the deformable projection
comprises two lips arranged one with respect to the
other in order to define a projection having a V-shaped
cross section.
Advantageously, the second profiled member is
arranged so as to be inserted fully in the reception
groove. This thus makes it possible not to impact the
visual appearance of the profiled rail.
CA 02942201 2016-09-09

Advantageously, the second profiled member is
produced from rigid or semi-rigid PVC. This also
facilitates the insertion of the second profiled member
in the first profiled member as well as removal thereof
by means of a suitable instrument while offering
sufficient resistance in rigidity to remain "embedded"
in the first profiled member when the cloth is attached
in the second profiled member and then subjected to a
tension for the purpose of producing the tensioned
ceiling.
Advantageously, the deformable projection is
produced from semi-rigid or flexible polymer.
The invention also relates to an additional
profiled member intended to be mounted removably in a
reception groove of a profiled member constituting a
profiled rail, said groove being delimited by at least
two lateral walls, at least one of the lateral walls
advantageously being able to hold a peripheral edge of
a cloth equipped with a harpoon, said additional
profiled member having a cross section in the form of a
U or V sized so as to be fitted in the reception groove
of the profiled rail in which it is intended to be
inserted, one of the arms of the U or V shape
comprising at least one deformable longitudinal
projection arranged so as to come into abutment against
a lateral wall disposed opposite the arm carrying the
deformable projection when the additional profiled
member is in place in the reception groove of the
profiled rail, one of the arms comprising a
CA 02942201 2016-09-09
8
longitudinal slot arranged so as to receive a shoulder
provided on one of the lateral walls of the reception
groove of the profiled rail in which it is intended to
be fitted.
The advantage of such a profiled member is being
able to be used with existing profiled rails that can
be used in tensioned ceilings made from PVC or Artolis0
textile cloth.
The additional profiled member reproduces all
the features of the second profiled member mentioned
above.
Advantageously, the other arm has a wall portion
forming an entry ramp. Advantageously, the deformable
projection has a flange profile. Another configuration
may also be provided in which the deformable projection
of the second profiled member advantageously comprises
two lips arranged with respect to each other so as to
define a projection having a V-shaped cross section.
Advantageously, one of the lips extends perpendicular
to a plane corresponding to the arm comprising the
deformable projection. According to an advantageous
configuration, the deformable projection is provided at
the free end of the arm. Advantageously, the deformable
projection extends beyond a plane corresponding to the
external face of the arm opposite to the arm carrying
the deformable projection. This thus makes it possible
to improve the wedging of the cloth between the
deformable projection and the relevant lateral wall of
CA 02942201 2016-09-09
9
the reception groove. Advantageously, the second
profiled member is produced from rigid or semi-rigid
PVC. Advantageously, the deformable projection is
produced from semi-rigid or flexible polymer.

DETAILED DESCRIPTION OF THE FIGURES
In relation to figures 1 to 3, a device 1 for
attaching a cloth for producing a tensioned-cloth false
ceiling is described, comprising a first profiled
member 2 and a second profiled member 4 able to be
embedded in the first profiled member 2. The first
profiled member 2 and the second profiled member 4 are
hereinafter referred respectively as the profiled rail
CA 02942201 2016-09-09
or main profiled member 2 and additional profiled
member 4.
In the embodiment illustrated, the main profiled
member 2, preferably made from aluminium, consists of a
5 profiled rail in the form of a right-angled triangle,
intended to be fixed to a support for the purpose of
attaching a cloth by its peripheral edges provided, to
do this, with an attachment means in the form of a
harpoon. Such a profiled member is known and the
10 general form of such a profiled member is described in
the applications FR 2952087 and FR 2970013 in the name
of the applicant. Any other form of main profiled
member may of course be provided without departing from
the scope of the invention. Such a profiled member is
intended in particular for attaching a PVC cloth.
Like any profiled rail used for installing a
cloth comprising attachment means, the profiled member
2 comprises a reception groove 20 intended to receive
the attachment means. In the embodiment illustrated,
the reception groove 20 has a U-shaped cross section
and is delimited by two lateral walls 21, 23 and a
bottom wall 22. The ends of the U-shaped lateral walls,
opposite to the bottom wall 22, define an opening 7 for
passage of the means for attaching the cloth in the
reception groove 20. In order to attach the means for
attaching the cloth, the internal face of one of the
lateral walls comprises a longitudinal attachment
shoulder 24. In the example illustrated, the attachment
shoulder 24 is provided on the internal face 230 of the
CA 02942201 2016-09-09
11
external lateral wall 23. External wall means the wall
furthest away from the space delimited by the ceiling
and the cloth when the latter is in place (awning).
Moreover, "internal face" designates a face disposed on
the groove side. Conversely, "external face" designates
a face disposed on the side opposite to the groove.
As will be seen later, the shoulder 24 is sized
so as to receive a slot 44 provided on the additional
profiled member 4. The fitting of the shoulder 24 in
the slot ensures the holding of the additional profiled
member 4 in the reception groove 20 of the main
profiled member 2. Advantageously, the shoulder 24 has
a flat attachment surface 240. The advantage of this
configuration is improving the holding of the
additional profiled member 4 in the reception groove 20
and thus preventing any unwanted withdrawal of the
additional profiled member 4 from the main profiled
member 2.
The additional profiled member 4, advantageously
produced from PVC, has a form substantially
complementary to that of the reception groove 20 of the
main profiled member 2.
More particularly, the additional profiled
member 4 is, in the embodiment illustrated, in the form
an elongate blade, preferably with the same length as
that of the main profiled member 2, with a
substantially U-shaped cross section. The arms 41, 43
of the blade are sized so as to extend over the entire
CA 02942201 2016-09-09
12
width of the lateral walls 21, 23 of the groove 20 of
the main profiled member 2. Width of the arms means the
distance separating the bottom wall 42 of the U shape
and the free end of said arms. Likewise, width of the
lateral walls of the reception groove means the
distance separating the bottom wall 22 of the groove
and the end of said lateral walls opposite to the
bottom wall 22.
The arm 41 of the additional profiled member 4
is provided, on its internal face 410, with semi-rigid
or flexible longitudinal projections 40. Support arm 41
will be spoken of hereinafter. The projections 40 are
arranged on the arm 41 and sized so as to come into
abutment against the internal face 430 of the arm 43 of
the additional profiled member 4 when the latter is in
place in the reception groove 20.
The arm 43 opposite to the one carrying the
projections 40 (arm 41) comprises a slot 44 sized so as
to receive the shoulder 24 of the lateral wall 23 of
the reception groove 20. In the embodiment illustrated,
the slot 44 has been formed by pressing of the arm 43.
It is provided on the arm 43 so that the width of the
downstream portion of the slot 44 (portion of the arm
43A) is substantially equal to the distance separating
the bottom wall 22 of the reception groove 20 the
shoulder 24.
The placing of the additional profiled member 4
takes place by elastic fitting of the additional
CA 02942201 2016-09-09
13
profiled member 4 in the groove 20 of the main profiled
member 2. To do this, the additional profiled member 4
is positioned until the slot 44 comes to snap onto
shoulder 24 of the groove 20 of the main profiled
member 2. Any movement between the additional profiled
member 4 and the main profiled member 2 is then
prevented, the additional profiled member 4 being held
in the main profiled member 2 by the shoulder 24. The
arm 43 thus forms a retaining arm.
In order to facilitate the insertion and
guidance of the peripheral edge of the cloth, the
portion of the arm 43 upstream of the slot 44 (arm
portion 43C) has an internal face arranged so as to
form a ramp 46 from the end of the arm 43 as far as the
fitted-in portion 43B of the arm 43A.
The terms "upstream" and "downstream" are
defined with respect to the movement of insertion of
the cloth in the additional profiled member 4. Thus the
zone situated between the pressed-in portion zone 43B
of the arm and the opening 45 allowing entry of the
cloth is defined as being an upstream zone of the
pressed-in portion, while the zone situated between the
pressed-in portion 43B and the bottom wall 42 is
defined as being a downstream zone of the pressed-in
portion 43B.
In the previously described embodiment, the
reception groove 20 has a U-shaped cross section. It is
of course obvious that the invention is not limited to
CA 02942201 2016-09-09
14
this type of groove and that the invention may be
implemented with a main profiled member 2 having a
groove in the form of a V or the form of a trough
provided with any bottom wall, the additional profiled
member 4 having in any event a cross section with a
complementary form.
Moreover, in the embodiment illustrated, the
additional profiled member 4 comprises four
projections, with different lengths, distributed over
the arm 41 between the end of said arm and a zone
situated facing the pressed-in portion of the arm 43.
The deformable projections also have a flange profile.
It is of course obvious that the projections are not
limited to this form and that any other form may be
provided without departing from the scope of the
invention. Likewise, the number of projections can vary
according to the dimensions of the additional profiled
member and the degree of clamping required.
From the above description, it will be
understood that the additional profiled member 4
enables a cloth with no attachment means to be attached
to a main profiled member initially intended for
attaching cloths provided with attachment means. Thus
the attachment device enables cloths of any type to be
used.
The attachment device also makes it possible to
combine mixed frames. This is because, when the main
profiled member comprises a plurality of reception
CA 02942201 2016-09-09
grooves suitable for holding an attachment means of a
cloth, this method can allow the attachment of a
plurality of cloths, some being equipped with
attachment means, the other having none. In the latter
5 case, an additional profiled member will be integrated
in the corresponding reception groove. Figure 1
illustrates the use of such a frame, the cloth 5 with
no attachment means being fixed in the reception groove
by clamping of projections against the internal face
10 430 of the retaining arm 43 while the cloth 6 provided
with attachment means 60 is fixed conventionally in the
groove 25.
In the previously described embodiment, the
attachment device 1 comprises only one additional
15 profiled member. It is course obvious that provision
can be made to integrate a plurality of additional
profiled members in the main profiled member, the form
and dimensions of said additional profiled members
being adapted to the form and dimensions of the
20 reception groove for which they are intended.
The invention is described above by way of
example. It will be understood that a person skilled in
the art is in a position to produce different variant
embodiments of the invention without departing from the
scope of the invention.
