Field of application
[0001] The present invention refers in its most general aspect to the field of curtains
and their assembly and more specifically to a curtain kit for Roman shades, pleated
shades, roller blinds, Venetian blinds, and the like and to its installation.
[0002] As known in the field of curtains and particularly those for indoor use intended
to be associated with a window space where there is a window frame, there is a great
need to have curtains that can be installed quickly and without causing any sort of
damage, so that their removal does not leave signs of damage to the window space,
or else to the frame of the window frame mounted in it.
[0003] To satisfy this requirement a solution provided by the prior art is described, for
example, in
US patent 4,782,882.
[0004] In particular, this document describes a device for supporting a Venetian blind in
which a support shaft for the blind is fixed against the jambs of a window space through
means that exert a pressure on such jambs, and that substantially act as tensioning
means of the shaft that act coaxially to it.
[0005] The present invention is based upon the consideration of the aforementioned requirement
and therefore a first object of the present invention is to provide a curtain kit
suitable for being associated with a window space that can be installed without damaging
the window space or a window (or door) frame mounted in it, and that is an alternative
to the solutions provided by the prior art.
[0006] A second object of the present invention is to provide a curtain kit, the installation
of which, as well as its removal, can be accomplished through quick and easy operations
that do not require any special manual ability or long time periods to carry them
out.
[0007] A further object of the present invention is to provide a curtain kit that is suitable
for being associated with a window space internally, i.e. within the window space
when located between its jambs, or with the window space externally, or else with
the window frame that is mounted in the window space, as well as with the panels of
the window frame, and furthermore substantially with the window-pane.
[0008] These and other objects are accomplished according to the invention by a curtain
kit comprising a box-shaped rigid support, which is substantially parallelepiped in
shape; a curtain associated with said rigid support; a pair of preferably identical
pieces of rectilinear profile, said pieces being shaped and sized to be removably
associated, to substantially act as a cap, with the respective opposite ends of said
box-shaped rigid support; at least one portion of adhesive of predetermined length
that is fixed or can be fixed to an outer wall of each of said pieces; at least one
projection formed in an inner wall of said pieces at a predetermined distance from
an end thereof, said projection constituting and end support for said rigid support.
[0009] Preferably, the curtain kit according to the invention also comprises an edge protruding
from said box-shaped rigid support, said protruding edge being suitable for cooperating
with the aforementioned projections of the pieces of profile, which according to a
preferred embodiment are substantially hook-shaped facing towards the aforementioned
end of each of said pieces.
[0010] Advantageously, the protruding edge extends at a lower end of the rigid support and
even more advantageously extends from a lower corner of the box-shaped rigid support,
substantially as an extension of a wall thereof.
[0011] Preferably, the aforementioned protruding edge extends continuously for the entire
length of the rigid support, i.e. along the entire lower corner of the box, making
a sort of veil or lip of the box. This, however does not exclude the possibility of
foreseeing a discontinuous protruding edge, i.e. many protruding edge sections, separated
from each other, arranged at side end portions of the box.
[0012] The pieces of profile preferably have a substantially squared U-shaped cross section,
in which the aforementioned projections are preferably foreseen at a wing of the piece
defined by the corresponding wing of the U-shaped section.
[0013] As far as the aforementioned adhesive portion is concerned, it should be noted that,
advantageously, it is a high-strength adhesive that is preferably in the form of a
continuous strip of adhesive arranged on a base portion of each piece, defined by
the corresponding base portion of the aforementioned U-shaped section.
[0014] Alternatively, and particularly in the case of installation directly on the window-pane
of the curtain kit according to the invention, the adhesive can be arranged at a wing
of the piece, as shall become clearer later on in the description.
[0015] It should also be noted that, advantageously, the curtain kit according to the present
invention comprises guide and counteraction means of the rigid support associated
with each piece of profile.
[0016] Advantageously, such guide and counteraction means, during the installation of the
curtain kit according to the invention, direct the rigid support towards the aforementioned
projections and, once installation is complete, counteract the box-shaped rigid support,
avoiding any undesired clearance between each of the side ends of the box-shaped rigid
support and the respective wings of a piece between which it is located.
[0017] Further characteristics and advantages of the present invention shall become clearer
from the following detailed description of some preferred embodiments, provided just
as an example, with reference to the attached drawings, in which:
- figure 1 schematically shows a perspective view of a curtain kit in accordance with
the present invention, associated with a window frame, in a configuration with the
curtain lowered (curtain extended);
- figure 2 shows, with parts separated, the curtain kit of figure 1 before its installation;
- figure 3 shows an enlarged view of some details of the curtain kit of figure 2;
- figures 4a and 4b show the curtain kit of figure 2 in accordance with an alternative
embodiment of the invention, in the double configuration of use, respectively with
the curtain lowered (curtain extended) and with the curtain raised (curtain shut away).
[0018] With reference to the aforementioned figures, a curtain kit according to the present
invention, suitable for being associated with a window space, is globally indicated
with 1.
[0019] The curtain kit 1 comprises a box-shaped rigid support 2, which is substantially
parallelepiped-shaped, with which a curtain 3 is associated, represented in the figures,
as an example, as a Venetian blind.
[0020] The curtain kit 1 also comprises a rotary shaft arranged inside the box-shaped rigid
support 2, and supported in it in a conventional way (not shown in the figures), on
which a raising cord 4 for moving the curtain 3 is wound.
[0021] In particular, the curtain 3, which comprises a plurality of slats 3a, is associated
in a
per se known way with the rigid support 2 at a lower portion 2a thereof through the aforementioned
raising cord 4 and through a further support ladder 5.
[0022] In accordance with the invention, the curtain kit 1 comprises a pair of preferably
identical pieces 6 of rectilinear profile which are shaped and sized to be removably
associated with the respective opposite ends of the rigid support 2, and a portion
of adhesive 7 of predetermined length fixed to an outer wall 8 of each of such pieces
6 and also a projection 9 formed in an inner wall 10 of each of the pieces 6 at a
predetermined distance from an end 11 thereof.
[0023] Advantageously, such a projection 9 constitutes an end support for the box-shaped
rigid support 2.
[0024] In accordance with a further aspect of the invention, the curtain kit 1 comprises
a protruding edge 12 that extends as a projection from the rigid support 2, and that
advantageously is suitable for cooperating with the aforementioned projections 9 of
the pieces 6 of profile, as shall become clearer in the rest of the description.
[0025] In particular, such a protruding edge 12 extends at the aforementioned lower portion
2a of the rigid support 2 and even more specifically extends from a lower corner of
the box-shaped rigid support 2, substantially as an extension of a wall thereof.
[0026] The protruding edge 12, moreover, preferably extends for the entire length of the
rigid support 2, in other words for the entire length of the aforementioned lower
corner, making a sort of veil or lip of the rigid support itself.
[0027] The aforementioned pieces 6 of profile preferably have a substantially U-shaped cross-section,
in particular squared U-shaped, in which the projections 9 are foreseen, in the inner
wall 10, at a wing 7a of the piece.
[0028] Preferably, the projections 9 are tooth or hook-shaped facing towards the aforementioned
end 11 of each piece 6 of profile, in other words facing upwards in the condition
of the curtain kit 1 in operation.
[0029] The portion of adhesive 7 is fixed onto the outer wall 8 of each piece 6, and in
particular is a high-strength adhesive in the form of a continuous strip of adhesive
of predetermined length preferably corresponding to the length of the respective piece
6. This, however does not exclude the possibility of foreseeing a different configuration
of the portion of adhesive, for example a configuration in points.
[0030] In particular and as shown in the examples of the figures, the portion of adhesive
7 is arranged at a base portion 7b of each piece with U-shaped section.
[0031] In this case the curtain kit 1 according to the invention is particularly suitable
for being associated with a window space, for example by attachment to the jambs of
the window space, or else to the frame of a window frame mounted in the window space
or to the shutters of the window frame, for example at the inner edges of the panel
of a window as is shown with particular reference to figure 1 in which the frame of
a window is indicated with 20.
[0032] On the other hand, in the case in which one wishes to install the curtain kit 1 directly
on the window-pane, for example, of a window as well as outside of the window space,
the portion of adhesive 7 can be foreseen, in accordance with the invention, on a
wing of each piece 6, such an embodiment not being illustrated in the figures.
[0033] The curtain kit 1 also comprises a pair of peel-away films 19, each associated with
a piece 6 for the protection of the respective portion of adhesive 7.
[0034] Regarding this, it should be noted that, in accordance with the invention, the adhesive
can also be in the form of adhesive applicable to each of the pieces 6, i.e. as an
adhesive to be applied at the assembly stage of the curtain kit, this embodiment not
being illustrated in the figures.
[0035] In a preferred embodiment, the curtain kit 1 also comprises guide and counteraction
means 14 of the box-shaped rigid support 2, associated with each piece 6 and arranged
on the inner wall 10 thereof.
[0036] In particular, such guide and counteraction means are in the form of at least two
shims 14 arranged one in front of the other at the wings 7a of a piece 6, a substantially
equal predetermined distance from its end 11.
[0037] Even more specifically with reference to a shim 14 and to a projection 9 arranged
on the same wing 7a of a piece 6, it should be noted that the distance between such
a shim 14 and the projection 9 is about the same as, and preferably slightly less
than the height of the box-shaped rigid support 2.
[0038] Preferably, at least one of the shims 14 is made in the form of a projection having
a free end.
[0039] The curtain kit according to the invention is completed by a substantially shaft-shaped
bottom element 16 associated with the bottom of the curtain 3, which, with reference
to the examples of the figures, has an upper profile closely following that of a slat
3a.
[0040] Such a bottom element 16 constitutes a weight for the raising cord 4 and for the
curtain 3, so as to allow it to be manoeuvred, making it easier to correctly arrange
the slats 3a in their sliding movement between the configuration with the curtain
raised (curtain shut away) to that with the curtain lowered (curtain extended).
[0041] It should be stated that for such a movement of the curtain 3, the curtain kit 1
comprises a control group 17 acting on the aforementioned rotary shaft, in the examples
of the figures a known manual control group that can be driven outside of the rigid
support 2 through a respective manoeuvring cord 18.
[0042] Furthermore, it should be noted that it is possible to foresee a different control
group, like for example a control group comprising an electric motor arranged inside
the rigid support 2 or outside it, such an alternative not being illustrated in the
examples of the figures.
[0043] With particular reference to figures 1 and 2, it should be noted that the aforementioned
pieces 6 of profile have a length substantially corresponding to that of the curtain
3 in the condition with the curtain completely extended or lowered.
[0044] In this case the pieces 6 of profile, which according to the invention act as a bearing
for the rigid support 2, also constitute a lateral guide for the curtain 3, containing
and laterally protecting the curtain 3 for the entire length of its sliding movement.
[0045] In accordance with an alternative embodiment of the invention, the pieces 6 of profile
can also be foreseen of limited predetermined length, for example a length equal to
or slightly greater than the height of the rigid support 2, as illustrated in the
example of figures 4a and 4b.
[0046] In such figures, the pieces 6 support the rigid support 2 and constitute lateral
guides for the curtain 3 for a first limited length of the sliding movement of the
curtain, in any case advantageously keeping on supporting the curtain.
[0047] Again with regard to the pieces 6, it should be stated that they are preferably pieces
of metal profile, more preferably of aluminium obtained by extrusion, in which the
aforementioned projections 9, just like the guide and counteraction means 14, are
made by drawing and/or shearing.
[0048] In use, the curtain kit 1 according to the present invention can be quickly associated
with a window space, both inside and outside of it, or associated with a window frame
mounted in the window space, for example with the frame of the window frame or with
its shutters as well as directly with the window-pane, and equally quickly removed
from it, through a small number of easy operations.
[0049] The installation of the curtain kit according to the invention firstly foresees the
removal of the protective film coating the portion of adhesive, then the pieces of
profile are fixed through the portion of adhesive, for example, to a window frame
mounted in the window space.
[0050] Once the pieces of profile have been fixed, the box-shaped rigid support is associated
with them, so that it is removable and substantially resting upon them, thanks to
the projections foreseen in the pieces.
[0051] In particular, pieces of profile and rigid support are associated so that the protruding
edge of the rigid support cooperates with the projections of the pieces, in other
words so that such a protruding edge engages the hook-shaped projections of each piece.
[0052] The operation of associating rigid support and pieces of profile is made easier by
the guide and counteraction means foreseen in the same pieces that in the installation
operation of the curtain kit direct the projecting edge of the rigid support towards
engagement with the aforementioned hook-shaped projections.
[0053] Moreover, once installation is complete, the guide and counteraction means counteract
the rigid support, in particular at the upper portion of the box-shaped support, preventing
each side end of the rigid support from being subjected to an undesired clearance
between the wings of a piece fitted substantially as a cap onto it.
[0054] To remove the curtain kit is will be sufficient to carry out reverse operations to
those above that will, if possible, be even easier to carry out.
[0055] The main advantage of the curtain kit according to the present invention consists
of its speed of installation and of the equally quick speed of removal without causing
any damage to the window space or to the window frame with which it is associated.
[0056] The attachment through adhesive of the pieces of profile and the absence of screws
and similar attachment devices, indeed, avoids the need to make holes, for example,
on the shutters of the window frame that, particularly, but not only, for high-quality
window frames, are highly undesired.
[0057] However, it should be noted that the curtain kit according to the invention can be
installed without exerting any potentially harmful stress on the window frame or the
window space.
[0058] Moreover, as the rigid support is associated with the pieces of profile in such a
way as to rest upon them, as described above, a quick and easy assembly between box-shaped
rigid support and pieces themselves and consequently a quick installation of the curtain
kit can be achieved.
[0059] The removal of the curtain kit according to the invention can, advantageously, be
partial in the case in which one wishes to just temporarily remove the box-shaped
rigid support, and thus the curtain associated with it, but not the pieces of profile
that support the rigid support, for example to more easily clean the box-shaped body,
the curtain and/or the window frame and/or the window-pane underneath the curtain
or to carry out repairs in the case of malfunction.
[0060] Advantageously, it should also be noted that after the installation on the shutters
of a window frame, directly on the window-pane or on the frame of the shutters, the
curtain kit according to the invention remains in almost direct contact with the window-pane,
thus allowing more effective protection against light.
[0061] Protection against light is also even more ensured by the pieces of profile that
act as lateral guides for the curtain, and that block the light that could filter
past the side of the window, at the longitudinal edges of the window-pane portion
of the window frame.
[0062] Again with regard to the protection against light radiation that the curtain kit
according to the invention is able to give, it should be noted that it is almost total,
in the condition with the curtain lowered, also thanks to the protruding edge of the
box-shaped rigid support that, by making, as mentioned, a sort of veil or lip, blocks
the light between the lower portion of the box-shaped rigid support and the first
of the plurality of slats of the curtain.
[0063] What has been stated with reference to the protection against light can be repeated
with regard to the visibility allowed through the curtain kit according to the present
invention that can, therefore, be totally prevented, ensuring total privacy, where
necessary, of the room in which the curtain kit is intended to be used.
[0064] A further advantage lies in the lateral protection that the pieces of profile give
to the curtain that, being subject to repeated movement, can be subjected to even
frequent breaking.
[0065] Advantageously, such a protection is ensured both with the curtain still, as a cover
for the end portions of the curtain, and with the curtain in movement with the pieces
of profile also acting as lateral containment guides during the sliding of the curtain.
[0066] Moreover, it is also ensured that the ends of the slats are protected from possible
undesired deformations, like those that can accidentally result from a knock, for
example of a person against the curtain.
[0067] A man skilled in the art can make numerous modifications to the curtain kit according
