[0001] The present invention relates to a system for the installation of netting/fabric/crystal
roll-up elements, suitable for both small and large size installations, realized by
means of telescopic guides enabling the mounting of said installations even on out-of-square
walls, while keeping the netting/fabric/crystal elements always perpendicular. The
use of a "zip", applied to the netting/fabric/crystal element for the purpose of its
relevant mounting, allows for a considerable clamping power in the guide even in adverse
weather conditions (i.e.: strong winds, etc.).
[0002] The systems currently in use usually employ rigid guides which allow for a good installation
of lengths of material, such as netting or fabrics, when the walls have been erected
up to standard.
[0003] When the walls are out-of-square, the installation of netting or fabrics can be carried
out through the employment of different expedients, such as, for instance, a shimming
of the guide base until the guide is level, and then, any fissure present is filled
with silicone- with subsequent longer installation time.
[0004] It should be taken into consideration, however, that the silicone may change colour
through time, therefore spoiling the overall effect of the installation.
[0005] Vice versa , installations carried out on out-of-square walls do not guarantee a
proper tensioning of said netting or fabric, compromising their relevant operation
and working life, beside spoiling their overall effect.
[0006] As regards the netting/fabric/crystal fastening onto the mobile or "end" component
of said wind-up roller, the system currently in use foresee hooking said netting/fabric/crystal
by means of a spinner or a double sided tape.
[0007] Even if widely in use, this solution cannot always guarantee a proper tensioning
of said netting/fabric/crystal, often resulting in unaesthetic bulges.
[0008] Moreover, by employing the above solution the overall effect is further compromised
as the netting/fabric/crystal soldering/sewing is always in full view.
[0009] On the other hand, the use of double sided tape could, in time, lead to a weakening
of the netting/fabric/crystal original anchoring onto the mobile section when, for
instance, strong winds blow.
[0010] The innovation that the present patent intends to claim comprises the use of a telescopic
guide, allowing for a correct installation of netting/fabric/crystal even when the
relevant walls are out-of-square, a mobile or "end" component and a wind-up roller.
Inside the latter a housing for a zip, on which said netting/fabric/crystal has been
previously soldered/sewn, is provided.
[0011] The present invention relates to a telescopic guide of extruded aluminium for a roll-up
element, comprising a channel to be fixed onto a wall and a guide element, inserted
on said channel, housing a zip-holder profile, inside which a netting/fabric/crystal
roller element slides; characterized by the fact that it comprises a telescopic system
for adjusting the position of said guide element in relation to said channel by adapting
said guide element position to any wall found to be out-of-square, and clamping means
to mechanically lock said guide element on said channel.
[0012] Furthermore, the present invention also relates to a mobile or "end" component of
a netting/fabric/crystal roller element, whose extruded aluminium body shape is basically
prismatic and with a flat bottom, characterized by the fact that a housing for the
zip of said netting/fabric/crystal element has been obtained directly on its rough
cast on its upper section.
[0013] With said telescopic system, it is possible to adjust the position of said guide
element used as a support base for the profile and its closing cover in relation to
the channel, adapting it to the out of square wall, and to mechanically lock said
guide on said channel by means of screws.
[0014] For the purpose of easing the coupling of said adjustable guide to said box, a PVC
feather key is provided on the channel upper section, which slides into the slot specially
provided for on said box.
[0015] The mobile or "end" component, also made of extruded aluminium,comprises a housing
for the insertion of said netting/fabric/crystal, previously fitted with a zip, and
is used for stretching out the netting/fabric/crystal material. A gaiter, acting as
a drainer, is provided on said "end" component external area, while, on the lower
area of this same section, a closing brush is fitted.
[0016] This invention further relates to a wind-up roller of extruded aluminium, located
inside a box, characterized by the fact that a housing for the insertion of a zip
of said netting/fabric/crystal element has been obtained directly on blank on its
outside diameter.
[0017] The present invention is herein further described by way of non-limitative examples
of realization, with reference to the figures on the accompanying drawings wherein:
- Fig. 1 is a perspective overall view of the installation system according to the present
invention;
- Fig. 2 is a view of section A-A of fig. 1;
- Fig. 3 is a view of section B-B of fig. 1;

[0018] The object of the present invention (fig. 1) is a system for a vertical or horizontal
installation of roll-up elements of netting/fabric/crystal, etc.
[0019] Said system comprises at least one telescopic guide (1) extended in a longitudinal
direction, a mobile or "end" component (2) basically set transverse to said telescopic
guide (1) with a housing for hooking up a leading edge of a netting/fabric/crystal
roll-up element (18), and a box (3) acting as container for a wind-up roller (21)
of said roll-up element (18).
[0020] Said roll-up element (18) is a flexible element realized, for instance, in netting/fabric/crystal,
and so on. The side edges, end edge and upper edge of said element (18) are provided
with a zip (8).
[0021] Said telescopic guide (1) fundamentally comprises three extruded aluminium sections
(fig. 2) extended longitudinally and parallel to each other:
- a channel (4) extendable in a longitudinal direction, to be fixed onto the relevant
wall for any final adjustments when said wall is out of square;
- a guide element (5) used as a support base and/or as a container for a zip-holder
profile (7), made of, for instance, PVC, inside which a zip (8), with the netting/fabric/crystal
element(18) soldered/sewn on, slides;
- a closing cover (6) interlocking said guide element (5) and said channel (4).
Said telescopic guide (1) is characterized by the fact that it represents a telescopic
system enabling to adjust the position of said guide element (5) in relation to said
channel (4) in a transverse direction to said channel (4), and to mechanically lock
said guide element (5) onto said channel (4) by means of a clamping device.
[0022] Said guide element (5) is slot mounted on said channel (4); said closing cover (6),
slot mounted on said guide element (5) and on the relevant stoppers (9) provided for
on the plastic closing caps (10) fitted on both ends of said guide element (5), allows
to hold in position a PVC profile (7). Said profile (7) houses a slot, where a sliding
zip (8), with said netting/fabric/crystal element (18)soldered/sewn on, is inserted.
[0023] Between said profile (7) and its relevant retaining housing, formed by said guide
element (5) and said closing cover (6), special brushes (11) are mounted, making said
coupling specially noiseless.
[0024] He position if said guide element (5) in relation to said channel (4) is adjustable
in a transverse direction so to compensate for any out of square sections of the wall
said channel (4) is mounted on. Once the cross position between said guide element
(5) and said channel (4) is adjusted, said guide element (5) is locked to said channel
(4) by means of suitable clamping means, such as, for example, a closing cover (6),
screwed into said channel (4), engaging said guide element (5) by slotting it.
[0025] Said channel (7) retaining housing is free to slide transversally on said channel
(4) allowing for any final adjustment, in presence of out of square walls.
[0026] On the upper end section of said channel (4) a closing lid (12) is mounted, provided
with a PVC key that may be inserted by sliding it into a special slot obtained on
the box (3) therefore easing, improving and holding in alignment said telescopic guide
(1) installation.
[0027] A mobile or "end" component (Fig. 3), consisting of, for example, a body of extruded
aluminium, is fitted for the purpose of stretching said netting/fabric/crystal element
(18).
[0028] Said "end" component (2) shape is fundamentally prismatic, with a flat bottom, and
it is transversally partitioned into an upper and lower section; inside the upper
section of said "end" component (2) a slot (13) for the insertion of said netting/fabric/crystal
element(18), previously
[0029] fitted with a "zip" (8), has been obtained from its rough cast. Inside the lower
section of said "end" component (2) a relevant space (14), where a ballast ( not depicted)
may be introduced for ballasting said profile according to requirements , and a slot
(15) for the introduction of a gaiter (16), acting as a drainer, have been obtained,
respectively.
[0030] A fastening system of said soldered/sewn netting/fabric/crystal element (18) is fitted
on the ends of said "end" component (2) (fig. 4), said system has been realized by
using special plastic plates (19) and relative plastic clamping inserts (20), also
used for said "end" component (2) sliding motion inside the relevant housing obtained
in said telescopic guide (1).
[0031] On the outside base of said "end" component (2) a brush (17) is provided enabling
to locate against any end face noiselessly, while guaranteeing a proper hold.
[0032] A box (3) (fig. 5) acting as a container for a wind-up roller (21), is located inside
said box (3).
[0033] Said wind-up roller (21) is of extruded aluminium and is provided, on the outside,
with a relevant rough cast slot (22) for the insertion of a zip (8) with said netting/fabric/crystal
element (18) soldered/sewn on.
[0034] Inside said wind-up roller (21), different ribs (23) are positioned, also realized
on the rough cast, providing to said roller structure a high flexural strength so
as to make it also suitable for large size installations.
[0035] Said wind-up roller (21) guarantees a saving in the relevant production time or replacement
time of said netting/fabric/crystal element (18) and a greater resistance of said
netting/fabric/crystal element (18) even in adverse weather conditions (strong wind,
etc.)
[0036] Lastly, it is clear that said telescopic guide, said mobile or "end" component and
wind-up roller herein described and depicted may be further modified without straying
from the scope of the claims hereof.
