[0001] The present finding relates to frames for windows or French doors and particularly
improvements to a self-rolling mosquito net provided with guides that are folded away
as the net is rolled into the rolling-net box when not in use so as to avoid cumbersome
elements that can hinder the way through the opening of the window frame.
More specifically the rolling-net box containing the rolling net is provided with
a handle by which it can be displaced by the user in order to put in/out the mosquito
net.
[0002] Patent Application No.
EP 1333148 A2 in the name of the same Applicant discloses a self-rolling mosquito net contained
inside an appropriate rolling-net box and provided with an upper fixed guide and a
lower movable guide able to be put inside a driving handle-bar operated by the user
during the rolling of the net and to come out from the same handle-bar upon pulling
out the rolling net.
Such solutions have some drawbacks even if they achieve the predetermined objects.
A first drawback consists of that the rolling-net box is arranged vertically and fixed
to the wall by snap fitting so that a fortuitous sudden impact can cause its detachment
from the wall, with the result of a damage of the fitting connection and/or the inner
rolling net, thus impairing the whole system.
A second drawback consists of that sometimes the upper and lower sides of the windows
or French doors are not perfectly parallel so that the mosquito net could jam where
the distance between the two sides is lower or have too much clearance where the distance
is greater, thus hindering in both cases the smoothness of the mosquito net along
its horizontal upper fixed guide and lower foldaway guide.
Similar jamming problems are caused by the thin thickness of the driving handle-bar
including the ends of the mosquito net having end slideable members the contact area
of which with the guide is very small.
[0003] The main object of the finding is then to overcome such problems by providing a mosquito
net having upper fixed guide means and lower movable guide means that are able to
be folded away into a section fixed to the wall during the re-wind step of the mosquito
net as well as to be pulled out from such section during the pulling-out step of the
mosquito net.
According to the present finding the rolling-net box containing the rolling net is
able to slide along such upper and lower guide means.
[0004] A better understanding of the finding will result from the following detailed description
with reference to the accompanying drawings that show a preferred embodiment thereof
only by way of a not limiting example.
[0005] In the drawings:
Figure 1 is a three-dimensional view of the finding as a whole in closed arrangement
and fitted on a frame;
Figure 2 is an exploded view of the finding of Fig. 1;
Figure 3 is a three-dimensional view of the finding of Fig. 1 without frame;
Figure 4, similar to Figure 1, shows the finding in open arrangement, i.e. with the
mosquito net being rolled into its rolling-net box.
[0006] Reference will be made thereafter to an embodiment in which the self-rolling mosquito
net is arranged vertically and its movement of opening/closing is directed horizontally
although the finding can be applied without any substantial modification to mosquito
nets that can be rolled/unrolled in the vertical direction.
With reference to the figures, the present finding includes a rolling mosquito net
for window frames provided with foldaway guides of the type comprising: a self-rolling
mosquito net 12 inside a suitable, lateral, movable rolling-net box 1 arranged vertically,
an upper fixed guide 4 and lower movable guide means 11 able to be put in a foldaway
manner into a first section 10 fastened to a vertical wall of the window during the
re-wind step of mosquito net 12, and able to be pulled out from such section 10 during
the pulling-out step of mosquito net 12.
The movable rolling-net box 1 is provided with a handle that allows the user to shift
it laterally to pull out easily mosquito net 12 rolled inside such rolling-net box
1 and to cause the box to abut against a second lateral limit stop section 13 arranged
vertically and fixed to the frame of the window opposed to the frame to which first
section 10 is fixed.
Such foldaway guide means consists essentially of a chain 11 quite similar to that
disclosed in the Patents mentioned above in the name of the same Applicant and having
one end hinged at the lower end of movable rolling-net box 1 by a support member 7
integral therewith, which chain 11 slides on a guide section 6 fixed to the ground
and having a particularly reduced thickness.
Advantageously, secured at the upper and lower ends of movable rolling-net box 1 are
members acting as "sliding blocks" able to facilitate the sliding with respect to
the upper fixed guide 4 and the thin guide section 6 secured to ground.
More particularly, provided at the upper end of movable rolling-net box 1 is a male
sliding block 8 which is provided with two "prongs" directed upwards and parallel
at a suitable distance from each other to be inserted between two pairs of longitudinal
ribs projecting downwards and arranged in the upper fixed guide 4 to guarantee a smooth
sliding of mosquito net 12.
Likewise, provided at the lower end of movable rolling-net box 1 is a female sliding
block 9 which is provided at the lower side with a recess or housing having a shape
which is conjugated to the shape of section 6 fixed to ground so as to slide easily
on the latter.
According to a peculiar feature of the finding, movable rolling-net box 1 is provided
inside at each upper and lower ends with a respective (not shown) thrust spring, each
of them presses the respective sliding block against the corresponding guide such
that the two sliding blocks of rolling-net box 1 are always in contact with the respective
guide, thus avoiding that rolling-net box 1 jams if the horizontal upper and lower
sides of the window or French door are not perfectly parallel.
Moreover, such thrust springs together with end sliding blocks 8 and 9 of rolling-net
box 1 having a rather wide contact area with the respective guides, preferably at
least equal to the cross section of rolling-net box 1, allows rolling-net box 1 and
then mosquito net 12 to be moved by an absolutely regular sliding motion.
[0007] Advantageously, in order to guarantee a rigid fastening to the wall, first section
10 is provided with an upper cover 2 having a slot 3 that allows its fastening to
the wall by a common fastening screw and with a lower mixtilinear member 5 to be secured
to the lower side of the window or French door, and the limit stop section 13 of movable
rolling-net box 1 is provided with holes (not shown) distributed along its length
to allow its fastening to the wall by screws. The present finding has been described
and illustrated according to a preferred embodiment thereof, however, it is self-evident
that those skilled in the art can make technically and/or functionally equivalent
modifications and/or replacements without departing from the scope of the present
industrial invention as defined by the claims.
