[0001] The invention belongs to the field of mechanics of the anti-mosquito net systems
that are used in horizontal door sliding.
[0002] According to the current state of the art, two types of anti-mosquito net (net) are
utilised in these systems: The flat net which is rolled and unrolled and the pleated
(with pleats) net which is folded and unfolded. The present invention is applied to
the anti-mosquito systems that have a pleated net (pleat), work with a fixed horizontal
guide which is permanently screwed on the floor and perform a horizontal movement.
[0003] The net is located folded in pleats (pleated), between two vertical cases, the retention
case and the sliding case and is folded and unfolded by moving within fixed horizontal
guides that are permanently fastened on the top and bottom part of the frame of the
opening.
[0004] In particular, according to the current state of the art, the whole system is like
a frame, which has as its two vertical sides the moving case of retention and the
fixed case of sliding, where the retention case is fastened and immobilized on one
of the vertical sides of the frame of the opening. At the same time, a fixed side
guide is fastened and immobilized on the opposite vertical side of the frame of the
opening. The sliding case moves between the retention case and the fixed side guide
and in a direction parallel to them. For the two horizontal sides, the one at the
top and the other at the bottom, the frame has two fixed guides fastened on the top
and the bottom sides of the frame of the opening, respectively. The sliding case moves
by sliding within the two horizontal guides, at the top and at the bottom, which are
made of aluminium, have a Π shape and usually have side walls of 4 mm height. In this
way the net is folded and unfolded within the horizontal guides. While the user slides
the sliding case, at the same time the pleated net of the net is unfolded. When the
user makes the reverse movement, namely when he moves the sliding case back to its
former position next to the retention case, simultaneously the pleated net is folded.
[0005] Furthermore, for the proper function of the anti-mosquito system, the pleated net
folds and unfolds its pleats, supported by ropes which run horizontally across its
length. The ropes are used so that when the pleated net is unfolded, they stretch
and hold the net stretched and unfolded in its place. They also assist in the refolding
of the net to its pleats.
[0006] The ropes are located horizontally and in equal distances between them and function
as follows:
The ropes that run across the upper middle part of the net form the top group of ropes.
[0007] The ropes that run across the lower middle part of the net form the bottom group
of ropes.
When the two groups have an equal number of ropes more stability is granted to the
system.
All the ropes start off at the side of the retention case, having their ends fixed
through buttons on a plastic axis. They run horizontally across the length of the
net and they go through similar buttons with an opening at their other end which also
are placed on a plastic axis. The whole system 'plastic axis - net with ropes - plastic
axis' is an independent component of the anti-mosquito net, which is introduced by
sliding within the two vertical guides; in particular, the plastic axis with the fixed
ends of the ropes on the buttons is introduced by sliding within the retention case
which is fastened permanently on the side of the frame of the opening. The opposite
plastic axis namely the one with the ends of the ropes that are going through the
opening of the buttons, is introduced by sliding within the sliding case which is
moved between the retention case and the fixed vertical side guide. After their passage
though the opening of the buttons, the ropes unify in two unified bundles of the same
number of ropes, the bundle that is formed by the ropes of the top group of ropes
and the bundle that is formed by the ropes of the bottom group of ropes.
[0008] Specifically, the ends of the ropes of the top group run through the sliding case
towards the bottom, creating a unified bundle that runs horizontally across the bottom
fixed horizontal guide and ends up and is fastened on the bottom end of the fixed
vertical side guide.
[0009] In a similar way, the ends of the ropes of the bottom group run upwards across the
sliding case, creating a unified bundle that runs horizontally across the top fixed
horizontal guide and ends up and is fastened on the top end of the fixed vertical
side guide.
[0010] At this point appears the following first technical problem: when the width of the
frame of the opening that is covered by the pleated net has big dimensions (more than
160 cm), the blow of the wind moves the net and in many cases it forces it out of
the two horizontal, top and bottom, guides. This problem appears in all anti-mosquito
systems that are installed on big openings and utilise a pleated net. This is due
to the fact that the net with pleats cannot stay still in its place, but thanks to
its pleats it permanently has a looseness and a flexibility in its movement. The ropes
that run across the net function as a support which holds the net in place, but only
under normal weather circumstances. When the wind blows, the support that the ropes
provide to the net of a big frame of opening is not sufficient to keep it within the
horizontal guides, at the top and the bottom. The exit of the net from the two horizontal,
the top and bottom, guides, has as a result the entrance of insects to the interior
of the frame, but also beyond that, it induces gradually the rip of the net at its
bottom part and thereafter to its destruction.
This technical problem could appear in all the anti-mosquito systems which utilise
pleated net, such as the systems that appear, as an example, in
EP 1653038 A1,
EP 2157274 A2,
EP 1959090,
EP11386022.5, and
JP 8-199948, when these systems are installed on a frame of opening with a big width.
[0011] A second technical problem is that, although the anti-mosquito net provides protection
against the insects, it does not at the same time provide shade to the space. If the
user wishes to also install a shading net on the same frame of the opening, that presupposes
an additional separate installation on the same frame of individual bars of aluminium,
which would be placed in continuation to the bars which are used for the anti-mosquito
system. That is to say that there would be two separate and independent systems, the
anti-mosquito system and the shading system installed one next to the other. The disadvantage
of the accumulative installation of the two systems is that the volume of the frame
of the opening is increased greatly. Moreover, the simultaneous use of both impedes
significantly the normal ventilation of the space. Lastly, in order to have access
to the shading system, the user every time has to fold first the anti-mosquito system
and subsequently to open or close the shading system.
[0012] Document
WO2012/117262 describes an anti-mosquito net system with the features mentioned in the introductory
part of claim 1 and which has the above-mentioned problems. The present invention
solves both the aforementioned technical problems. As stated above, the side guide
is fastened on one of the vertical sides of the frame; the retention case is fastened
on the opposite vertical side and between them on a parallel position the sliding
case is located, which with its moving it folds and unfolds the net. The invention
consists in the following: Between the retention case which is fastened permanently
on the one vertical side and the sliding case which moves parallel to it, a second
sliding case is installed, which also moves in parallel to the previous two cases.
Due to a special end component which is located on the top and bottom end of the second
(intermediary) sliding case, the passage of the ropes from the one panel of net consecutively
into the next one is made possible without interrupting the ropes at any place. This
technical characteristic, namely the special end component of the intermediary sliding
case, thanks to which it is technically rendered feasible for the net panels to be
independent while the ropes that connect them can be united, attributes to the system
the following property: Depending on the length of the opening that is meant to be
covered by the anti-mosquito system, more than one additional intermediary sliding
cases can be installed, all being always moved in parallel to one another; between
the cases the independent panels of net are introduced, all being united with the
same ropes. Therefore the opening of the frame is not covered by a single anti-mosquito
net with a big surface but by more panels of net with a smaller surface, which do
not exit their place due to wind but they remain firm in their position within the
small dimensions of the frames that are formed by the sliding cases and the horizontal
guides. This way the first technical problem that was mentioned earlier is solved.
[0013] Additionally, the second (intermediary) sliding case and the special component on
its top and bottom edge separate the panels of the net from each other. Therefore,
the anti-mosquito system may have two panels of anti-mosquito net only, or one panel
with an anti-mosquito net and one with a shading net. This way, the shading net is
incorporated into the anti-mosquito system and becomes an alternative choice for the
user who thus acquires an appliance with two functions in one, namely both an anti-mosquito
protection and a shading, so as depending on the hour of the day he can use whichever
of the two nets he needs.
This way the present invention resolves also the second technical problem mentioned
earlier, that of the increase in the volume of the frame of the opening and the difficulty
that presented by both the placement and the use of the cumulative placement of both
systems, the anti-mosquito one and that of the shading. There is no anti-mosquito
system with an incorporated shading net in the current state of the art, which is
the reason why no particular examples of pre existing Patents are cited here.
[0014] Furthermore, the invention is produced in a kit form, which means that the user does
not have to wait for the execution of his order in specific dimensions of height.
In particular, the product can be produced directly in specific categories of height
for the cases and the side guide, e.g. "kit with a height of cases and guide from
1900 up to 2200 mm", "kit with a height from 2201 up to 2500 mm" and "kit with a height
from 2501 up to 2800 mm". That results in an easiness and speed of placement since
the technician that places it assembles the anti-mosquito system in situ in a very
short time.
[0015] The 18 Drawings that accompany the invention illustrate in brief, the following:

[0016] An example of application of the current invention follows, with a detailed description
and reference to the attached drawings.
[0017] As shown in Drawings 1 - 10, the panels of the pleated anti-mosquito net (7a and
7b) can both be anti-mosquito nets (drawings 1-2, 6-10), or one can be an anti-mosquito
net and the other a shading net (drawings 3-5), or both can be shading nets.
Moreover, the net panels could be two (drawings 1-7), or three (drawings 8-10) or
more.
[0018] Regardless of the type of net that the user chooses, the net panels, when they are
two in number, they are placed as follows (drawings 1-7): the first net panel (7a)
is located between the fixed retention case (8) which is fastened on the vertical
side of the frame of the opening and the intermediary sliding case (9), the second
net panel (7b) is located between the intermediary sliding case (9) and the sliding
case at the side (10). Whereas when all the net panels are three in number (drawings
8-10) the third panel (7c) is located between the second intermediary sliding case
(45) and the sliding case at the side (10).
[0019] As mentioned earlier, according to the systems of the current state of the art, the
net is run across by ropes placed horizontally and at equal distances between them,
which are used for the folding and unfolding of the net.
The main technical feature of the current invention is that the ropes run all the
pleated net panels successively without being interrupted, from their start at the
side of the fixed retention case, up to their ends at the vertical fixed side guide.
That is, the ropes are united and are not interrupted anywhere. This is achieved thanks
to the special end component that exists at the top (17) and bottom (27) end respectively
of the intermediary sliding case (9) (drawings 11-13).
[0020] More specifically, the ropes function as follows (drawing 2):
there are six ropes (1, 2, 3, 4, 5, 6) that are unified in two groups of the same
number of ropes, the bottom group (1, 2, 3) which includes the ropes that run across
the net from its middle to its bottom and the top (4, 5, 6) group which includes the
ropes that run across the net from its middle to its top part. All six ropes have
one of their ends fixed on special button components (11a, 11b, 11c, 11d, 11e, 11f)
which are located on a plastic axis (12) which is located on the edge of the net (7a),
within the retention case (8).
The first rope (1) from the bottom part of the net (7a) has its end fixed on the first
button (11a).
The next rope towards the top (2) has its end fixed on the next button (11b).
In a similar way all the ropes are linked with the buttons successively: rope (3)-button
(11c), rope (4)-button (11d), rope (5)-button (11e) and rope (6)-button (11f).
[0021] The six ropes (1-6) all run across the first net (7a) horizontally and at equal distances
between them and they reach buttons with holes (13a-13f) which are located on a plastic
axis (14) which is located on the opposite edge of the net (7a), within the intermediary
sliding case (9). They enter through the transparent buttons (13a-13f) in the same
successive sequence, namely rope (1)-button (13a), rope (2)-button (13b), rope (3)-button
(13c), rope (4)-button (13d), rope (5)-button (13e) and rope (6)-button (13f).
[0022] Thereafter their directions change according to the group.
[0023] The bottom group: the ropes of the bottom group (1, 2, 3) are heading as one unified
bundle (20) towards the top horizontal guide (15), they run as a bundle (20) around
a pulley (16) which is located on a top end component (17) of the intermediary sliding
case (9), they descend as a bundle (20) and they branch off one after the other by
passing at a sequence (1, 2, 3) through the top buttons with holes (18f, 18e, 18d)
respectively, which are located on a plastic axis (19) within the intermediary sliding
case (9).
The rope (1) which in the first panel of net (7a) is located at its lowest part and
passes through the first button from the lowest part of the bottom of the net (13a),
when it runs across the second panel of net (7b) passes through the first on the uppermost
part of the net (7b) top button with holes (18f).
Likewise and successively the second rope (2) which in the first panel of net (7a)
is located second in sequence immediately above the first (1) rope, counting from
the bottom up, and it passes through the second on the bottom part of the net (7a)
button with holes (13b), when it runs across the second panel of net (7b) it passes
through the second on the top part of the net (7b) top button with holes (18e), under
the first (1) rope.
Likewise and successively, the third rope (3) which on the first panel of net (7a)
is located third in the sequence immediately above the second (2) rope, counting from
the bottom up and passes through the third on the lower part of the net (7a) button
with holes (13c), when it runs across the second panel of net (7b) it passes through
the third on the top part of the net (7b) top button with holes (18d), under the second
(2) rope. Thereafter all three ropes (1, 2, 3) run across the second net (7b) horizontally
and in equal distances between them and they reach corresponding buttons (37f, 37e,
37d), which are located on a plastic axis (38) which is located on the opposite edge
of the net (7b), within the side sliding case (10).
Afterwards they are unified once again in a united bundle (20) and are directed vertically
towards the bottom horizontal guide (21). They run as a bundle (20) around a pulley
(22) which is located on a bottom end component (23) of the side sliding case (10),
they run along the bottom horizontal guide (21) within its limits and across its length,
and with the help of an opening (31) which is located on the end component (39) at
the bottom part of the fixed side guide (24) they enter into the vertical fixed side
guide (24), and are adjusted within it at its bottom part.
[0024] The top group: the ropes of the top group (4, 5, 6) are directed as a united bundle
(25) towards the bottom horizontal guide (21), they run as a bundle (25) around a
pulley (26) which is located on a bottom end component (27) of the intermediary sliding
case (9), they ascend as a bundle (25) and they branch one after the other passing
through at a sequence (6, 5, 4) the bottom buttons with holes (18a, 18b, 18c) respectively,
which are located on a plastic axis (19) within the intermediary sliding case (9).
[0025] The rope (6) which on the first panel of net (7a) is located on its upper part and
passes through the first on the uppermost part of the net button with holes (13f);
when it runs across the second panel of net (7b) it passes through the first on the
lowest part of the net (7b) lower button with holes (18b).
[0026] Likewise and successively the next rope (5) which on the first panel of net (7a)
is located second in sequence, counting from top to bottom, and it passes through
the second on the top part of the net (7a) button with holes (13e); when it runs across
the second panel of net (7b) it passes through the second at the bottom part of the
net (7b) bottom button with holes (18b).
[0027] Likewise and successively, the immediately next rope (4) which on the first panel
of net (7a) is located third in the sequence, counting from top to bottom and passes
through the third on the top part of the net (7a) button with holes (13d); when it
runs across the second panel of net (7b) it passes through the third on the bottom
part of the net (7b) bottom button with holes (18c).
[0028] Thereafter all three ropes (4, 5, 6) run across the second net (7b) horizontally
and at equal distances between them and they arrive at buttons (37c, 37b, 37a) respectively,
which are located on a plastic axis (38) which is located on the opposite side of
the net (7b), within the side sliding case (10).
[0029] Afterwards all three ropes (4, 5, 6) are united once again into a united bundle (25)
and they head vertically towards the top horizontal guide (15). They run as a bundle
(25) around a pulley (28) which is located on a top end component (29) of the side
sliding case (10), they run across the top horizontal guide (15) through itself and
along its length, and with the help of an opening (30) which is located on the end
component (40) at the top part of the fixed side guide (24) they enter into the fixed
vertical side guide (24) through its top part, and they are fastened inside it.
[0030] As seen above, the bottom group of ropes (1, 2, 3), which runs across the first net
(7a) at its bottom part, runs across the second net (7b) at its top part, while conversely,
the top group of ropes (6, 5, 4), that runs across the first net (7a) at its top part,
runs across the second net (7b) at its bottom part, where the ropes are united without
any interruption. This is achieved thanks to the intermediary sliding case (9) and
the top (17) and bottom (27) end components with pulleys that it has.
[0031] Simultaneously, as the ropes pass through the end components (17, 27), their sequence
is reversed completely, namely the rope (1) which is last on the bottom part of the
first net (7a), following its passage through the end component (17) it enters first
into the top part of the second net (7b); the immediately next rope which is second
(2) at the bottom part of the first net (7a), following its passage through the end
component (17), it enters second into the top part of the second net (7b) and so forth,
until the rope that is located on the uppermost level (6) of the first net (7a), following
its passing through the end component (27) it enters last into the bottom part of
the second net (7b).
[0032] In other words, the rope (1) that exits through the lowest button (13a) of the first
panel of net (7a) enters through the uppermost button (18f) of the second panel of
net (7b),
the rope (2) that comes out of the immediately next towards the top button (13b) of
the first panel of net (7a) enters into the immediately next towards the bottom button
(18e) of the second panel of net (7b) and the rope (3) that exits through the button
(13c) immediately after the next one towards the top of the first panel of net (7a),
it enters into the button (18d) after the next towards the bottom of the second panel
of net (7b).
[0033] Similarly with the other group of ropes, where the rope (6) that exits through the
uppermost button (13f) of the first panel of net (7a) enters at the lowest button
(18a) of the second panel of rope (7b),
the rope (5) that exits through the button (13e) immediately next towards the bottom
of the first panel of net (7a), it enters into the button (18b) immediately next towards
the top of the second panel of net (7b) and the rope (4) that exits through the button
(13d) after the next towards the bottom of the first panel of net (7a), it enters
into the one after the next towards the top button (18c) of the second panel of net
(7b).
[0034] This particular sequence of passage of the ropes is absolutely necessary for the
proper functioning of the system.
[0035] All the axis (12, 14, 19, 38) with buttons have the same length. All the buttons
(11a-11f, 13a-13f, 18a-18f, 37a-37f) of the panels of net (7a and 7b) are placed at
the same height and on the same and equal distances between them, so as the ropes
entering through the buttons and running across the nets are always at horizontal
lines, that have the same distance between them and are parallel.
[0036] If the opening of the frame is big, a third and a fourth panel of net could be used,
by utilising additional sliding cases. Each time the two bundles of ropes will be
entering through the end components at the top and the bottom end of the intermediary
sliding cases, and will exchange their position, namely the top group will become
bottom group and vice versa and the ropes will reverse successively their position
according to the above mentioned procedure, until they reach the side sliding case
(10). Then they will run across the two horizontal guides and they will be fastened
within the vertical side fixed guide (24).
[0037] That technical feature of the continual alteration of the sequence of the ropes up-down,
with the same sequential inversion, and the maintenance of all the ropes on parallel
horizontal lines while simultaneously the ropes are united and are not interrupted
anywhere from their starting point on the axis (12) of the retention case (8) up to
their point of termination on the fixed vertical side guide (24), attributes great
stability to the anti-mosquito screen system as a whole and it renders it absolutely
solid at the continual movement of the side sliding case (10) and also of the intermediary
sliding case (9) for the continual folding and unfolding of the panels of net (7a)
and (7b). The same stability is displayed also by the system when more than one intermediary
sliding case is used.
[0038] Drawings 3, 4 and 5 present the anti-mosquito screen system with one intermediary
movable sliding case (9) and with two panels of net, where one of the panels is an
anti-mosquito net (7a) and the other is a shading net (7b). In drawing 3 both nets
(7a and 7b) are partially unfolded. In drawing 4 the shading net (7b) is entirely
folded in its pleats between the side sliding case (10) and the intermediary sliding
case (9); as far as the anti-mosquito net is concerned, it is fully unfolded. On the
contrary, in drawing 5 the shading net (7a) is entirely folded in its pleats between
the intermediary sliding case (9) and the retention case (8), whereas the anti-mosquito
net (7a) is entirely unfolded.
[0039] The ropes (1, 2, 3, 4, 5, 6) (drawing 3) run always in succession across both panels
of pleated nets (7a and 7b), from their start on the axis (12) on the side of the
fixed retention case (8) until their termination on the fixed vertical side guide
(24). They are united and are not interrupted at any point. The fact that the first
panel of net is an anti-mosquito net (7a) whereas the second is a shading net (7b)
does not change in any way the way of functioning of the invention, based on all facts
analyzed earlier regarding the case where both panels of net were anti-mosquito nets
(drawing 2).
[0040] When the system has both types of net, that is the anti-mosquito net (7a) and the
shading net (7b), its use is implemented as follows: the user pulls the side sliding
case (10) and directs it up to the vertical side guide (24) so that the nets are unfolded
(7a and 7b) (drawing 3). Then, the user has two options: if it is daytime and he wishes
to shade the space, he slides the intermediary sliding case (9) towards the retention
case (8) up to the point that both the cases (9 and 8) touch each other. At this point,
the first panel with the anti-mosquito net (7a) is entirely folded between the two
cases, the sliding one and the retention one (9 and 8) (drawing 5). On the contrary,
if it is night and the user wishes to utilise the anti-mosquito net (7a), he slides
the intermediary sliding case (9) towards the opposite direction, namely towards the
side sliding case (10) (drawing 3) and in this way the first panel with the anti-mosquito
net is unfolded (7a), whereas the second panel with the shading net (7b) is folded
in its pleats between the intermediary sliding case (9) and the side sliding case
(10) (drawing 4).
[0041] Drawing 6 illustrates an anti-mosquito screen system with a side opening on both
ends and with three sliding cases, two at the sides (10, 8) and one intermediary (9),
and two panels of net (7a and 7b).
[0042] The systems with the side opening on both sides already exist in the current state
of the art, but they only have one panel of net, not two or more, a feature made possible
through the application of the present invention with the intermediary movable sliding
case (9).
[0043] In this case also nothing changes in the way the invention functions, compared to
the issues analyzed above in the case that the system had only one side opening (plans
1-5).
[0044] The only difference consists in the following:
The case which in the system with one side opening is a retention case (8) permanently
fastened on the vertical side of the frame of the opening, on the occasion of the
bilateral opening is also a side sliding case and moves like the other two sliding
cases (9 and 10). For that reason, this implementation of the system calls for a second
vertical side guide (36) (drawings 6-7) and two pulleys (32, 33) on the second sliding
case (8). In this implementation the ropes start off as two united bundles from the
second vertical side guide (36) (drawing 7). The three ropes (1, 2, 3) form the first
bundle of ropes (20) which starts off from a point on the top part of the second vertical
side guide (36), while the other three ropes (4, 5, 6) form the second bundle of ropes
(25), which starts off from a point on the bottom part of the second vertical side
guide (36). Thereafter the bundles go through a top opening (34) and a bottom opening
(35) of the end components (41 and 42) of the top and bottom end respectively of the
vertical side guide (36) and they enter horizontally into the two horizontal guides
at the top (15) and the bottom (21). The top bundle (20) enters into the top horizontal
guide (15) and the bottom bundle (25) enters into the bottom horizontal guide (21).
At that point they run respectively around a top pulley (32) and a bottom pulley (33)
which are located on a top end component (43) and at a bottom end component (44) on
the top and the bottom end of the side sliding case (8). Within the sliding case (8)
there is the axis (12) with the buttons with holes (11a-11f) from which the ropes
will go through (1-6). The top bundle (20) of ropes (1, 2, 3) descends through the
sliding case (8) and the ropes (1, 2, 3) go through the three buttons at the bottom
(11a, 11b, 11c) respectively, whereas the lower bundle (25) of ropes (4, 5, 6) ascends
through the sliding case (8) and the ropes (4, 5, 6) go through the three buttons
at the top (11d, 11e, 11f) respectively. From that point on the function of the system
is absolutely similar to the one described above and is illustrated in the drawings
1-5.
[0045] The drawings 8, 9, 10 present an anti-mosquito screen system with a third panel of
net (7c) and the addition of a second intermediary sliding case (45), between the
side sliding case (10) and the intermediary sliding case (9).
[0046] As illustrated in drawing 9, the second sliding case (45) (drawing 9) has adjusted
on its top and bottom end the special end components (51) and (52) respectively, which
are similar to the end components (17) and (16) that belong to the first sliding case
(9) and function in exactly the same way. The third panel of net (7c) is positioned
between the second intermediary sliding case (45) and the side sliding case (10).
The panels of the nets of the system could be, based on the user's choice, all anti-mosquito
nets, or all shading nets, or some anti-mosquito and some shading nets. At the systems
that have three panels of net (7a, 7b, 7c), the ropes function as follows: The ropes
run across the first (7a) and the second (7b) panel of net according to the way described
in detail above, with reference to the drawings 1-5. Then, the ropes arrive at the
edge of the second net (7b) and they go through buttons with holes (53a-53f) which
are located on the axis (55) at the edge of the net (7b) and afterwards they are again
separated into two bundles.
[0047] The bundle (20) with the ropes of the first group (1, 2, 3) is directed towards the
bottom horizontal guide (21) and goes around a pulley (57) which is located within
the end component (52) at the bottom end of the second intermediary sliding case (45).
Afterwards the ropes again ascend and branch, by passing through bottom buttons with
holes (54a, 54b, 54c) respectively, which are located on an axis (58) on the edge
of the third panel of net (7c).
[0048] The other bundle (25) with the ropes of the second group (4, 5, 6) is directed towards
the top horizontal guide (15) and runs around a pulley (56) which is located within
the end component (51) at the top end of the second intermediary sliding case (45).
Thereafter the ropes again descend and branch, by passing, through top buttons with
holes (54d, 54e, 54f) respectively, which are located on the axis (58) at the edge
of the third panel of net (7c).
Therefore in this case, once again the sequence of passage of the ropes is reversed
in comparison to the sequence of passage that they followed running across the second
panel (7b) of net.
Thus, the rope (6) that exits through the lowest button (53a) of the second panel
of net (7b) enters through the uppermost button (54f) of the third panel of net (7c),
the rope (5) that exits through the immediately next towards the top button (53b)
of the second panel of net (7b), it enters through the immediately next towards the
bottom button (54e) of the third panel of net (7c) and
the rope (4) which exits through the button after the next towards the top (53c) of
the second panel of net (7b), it enters through the one after the next towards the
bottom button (54d) of the third panel of net (7c).
[0049] The same happens to the other group of ropes, where the rope (1) which exits through
the uppermost button (53 f) of the second panel of net (7b) enters through the lowest
button (54a) of the third panel of net (7c),
the rope (2) which exits through the immediately next towards the bottom button (53e)
of the second panel of net (7b) enters the immediately next towards the top button
(54b) of the third panel of net (7c) and
the rope (3) which exits through the one after the next towards the bottom button
(53d) of the second panel of net (7b) enters through the one after the next towards
the top button (54c) of the third panel of net (7c).
[0050] That specific sequence of passage of the ropes is absolutely necessary for the proper
function of the system.
[0051] Thereafter all six ropes run horizontally at equal distances between them, across
the third net (7c). They go through the buttons with holes (37a-37f) which are located
on the axis (38) at the end of the net (7c), and then the function that has been described
above in relation to drawing 2 is repeated and the system with the two panels of net
(7a and 7b), namely with the two bundles of ropes (20 and 25) that reverse the direction
of their route and are fastened with the same way on the top and bottom part of the
fixed vertical side guide (24).
The system functions with the same way if there are more than three panels of ropes,
namely for every additional panel of net an additional intermediary sliding case is
used which has end components (17) similar with the above on the top and bottom of
its end and which is placed in between the other sliding case. In every additional
panel of net that is used, the sequence of passage of the ropes is again reversed
in the way that is described in detail above.
[0052] Drawing 10 shows an anti-mosquito screen system with a third panel of net (7c) and
openings on both sides. In this case the technical features and the operation of the
system is completely similar with the function that has been described above in reference
with drawing 7, that is a second vertical side guide is required (36) and two pulleys
(32, 33) on the second sliding case (8). Also is required a second intermediary sliding
case (45) according to the way of operation that has just been described with reference
to the drawings 8-9.
[0053] Drawings 2, 11, 12, 13, 18 illustrate the special end component (17 and 27) which
is adjusted on the top and bottom end of the intermediary movable sliding case (9)
(drawing 11a). Thanks to that component the passage of the ropes from one panel of
net (7a) successively to the next (7b) is rendered feasible, without any interruption
made on the ropes. The component (17) has on both of its opposite sides two slottings
(46) within which the panels of the pleated net (7a and 7b) are placed and fastened
(drawing 11b). At its middle there is an opening with holes (47) (drawing 12a and
13a) in which a pulley is inserted (16) rotating around an axis (49) (drawings 12a,
13c). The axis (49) enters into the opening with holes (47) and is fastened in a horizontal
position within two slottings (48) (drawings 12a, 13c) which exist on the walls of
the opening (47) with holes. Around the pulley (16) the bundle of the ropes (20) runs
(drawings 11a, 11b, 11c and 12b) by moving within a configured recess or cavity (50)
that is located on the surface of the pulley (16) (drawings 12a, 13a, 13b, 13c).
[0054] The opening with holes (47) within the end component (17) has a shape similar to
that of the pulley (16), leaving a gap only at the point where the recess is located
(50). That has as a technical result the bundle of the ropes (20) to be running around
the pulley (16) (drawings 12b and 13 a) and moving around it while remaining at all
times in the recess (50) on the surface of the pulley. This way the bundle of the
ropes (20) runs continually unobstructed around the pulley (16) and as a result of
that the net (7a and 7b) folds and unfolds its pleats unhindered.
[0055] The same exactly technical features with the end component (17) of the top end of
the sliding case (9), are present on the end component (27) which is adjusted on the
bottom end of the intermediary moving sliding case (9) (drawing 2), through which
enters the bundle (25) of the top group of ropes (4, 5, 6). Both end components (17
and 27) function in exactly the same way.
[0056] Lastly the drawings 14, 15, 16 and 17 illustrate the manner of assemblage of the
system in three steps. The assemblage is done on the spot of placement and the system
is in a kit form.
[0057] Drawing 14 illustrates the first step of assemblage:
At this stage the system consists of the side fixed guide (24), the side sliding case
(10), the intermediary sliding case (9), the retention case (8), with the two panels
of pleated net (7a and 7b) folded between them. The bottom end components of the cases
and the side guides (39, 23, 27, 42) are in place, whereas on the contrary the top
end components (40) of the side guide (24), a component (29) of the side sliding case
(10), a component (17) of the intermediary sliding case (9) and a component (17) of
the retention case (8) have not yet been installed in their position. The bundles
of the ropes (20, 25) are running through the components which are not yet placed
(40, 29, 17).
[0058] The placement technician cuts and discards as a waste part of the two sliding cases
(10 and 9) of the side guide (24) of the retention case (8) and of the two pleated
nets (7a and 7b). The cutting of all those components is done at a spot between the
indication minimum and maximum, that appears on the side sliding case (10). The indication
of the lowest point (minimum) is always at least 2cm above the height where the uppermost
ropes are located (6 and 1, drawing 2), that run across the nets (7a κal 7b). The
minimum and maximum indications are placed on the cases by the manufacturer. The placement
technician can cut the components at whichever height between the two points of min.
and max. which are indicated on the cases.
[0059] Drawing 15 illustrates the second step of assemblage of the kit. The top end components
(40, 29, 17, 41) are placed on the fixed side guide (24) and on the cases (10, 9,
8) respectively and they are fastened. Then the pulleys (28 κal 16) are introduced
into the end components (29 κal 17) of the side (10) and the intermediary (9) sliding
case respectively. Finally, the bundle (25) of the ropes (4, 5, 6) runs through a
button that exists on the top part of the fixed side guide (24), its length is adjusted
and stabilized.
Drawings 16 and 17 present the kit completely assembled and ready to be fastened on
the frame of the opening that is intended to cover.
[0060] The invention is applicable on all anti-mosquito nets that have a pleated net and
a horizontal movement.
