DETAILED DESCRIPTION OF THE INVENTION
(19) An example of application of this invention follows with a detailed description and reference to the attached drawings.
(20) As FIG. 1 illustrates, the autonomous anti-mosquito system has on the left and on the right two cases, the sliding case (1) and the retention case (2), in a vertical position, parallel to each other.
(21) At the initial position, the net is folded and the sliding case (1) is next to the retention case (2). When the sliding case (1) begins moving towards the side fixed guide (24) the pleated net (7) unfolds and the opening closes, whereas when it moves to the opposite direction towards the retention guide (2), the pleated net (7) folds and the opening opens.
(22) The net (7) is run horizontally by six retention ropes (1a, 2a, 3a, 4a, 5a, 6a) all placed in a horizontal position and equally spaced apart from one another. All the ropes have trucks (21) as common starting points, which are located at that side of the net (7) which are found within the retention case (2). The ropes run across the net (7) horizontally, they reach the trucks (20) at the opposite side of the net (7) which are found within the sliding case (1), they run through the trucks (20) and are all directed upwards, to a detachable top edge (22) of the sliding case (1) within which there are two pulleys, the first (23) above the second (28) or vice-versa. The second pulley is mounted in block 46.
(23) The six retention ropes (1a, 2a, 3a, 4a, 5a, 6a) as a bundle run around the above pulley (23), then cross horizontally the upper fixed horizontal guide (25) towards the vertical fixed side guide (24), which has a detachable top edge (38) with an opening. The six retention ropes (1a, 2a, 3a, 4a, 5a, 6a) pass through the opening of the upper detachable edge (38) of the vertical fixed side guide (24), continue downwards as a bundle and are fixed on an adjuster (27) at the upper part of the vertical fixed side guide (24).
(24) At the first of the upper trucks (21) where the top rope (6a) is fastened, one edge of the wire rope (43) is fastened to the same truck. The upwardly extending wire rope passes through an opening of the upper part of the detachable upper end (42) of the retention guide (2), the opening being at a height above the height of the net (7) and then crosses the upper fixed horizontal guide (25) in a position horizontally over the net, having the same direction with the unfolding direction of the net, then passes through the second pulley (28) inside the removable upper end (22) of the sliding case (1) at a height above the height of the net (7) without touching it, continues vertically towards the lower fixed horizontal guide (17), passes around the pulley (31) in the detachable lower edge (32) of the sliding case (1); then it is directed through the horizontal guide (17) towards the detachable lower end (35) with the opening of the fixed vertical side guide (24), passes through the opening of the end (35), continues upwards and is fixed to an adjuster (29) in the lower part of the vertical fixed side guide (24). Thus, the wire rope (43) starts with one edge at the upper truck (21) in the retention guide (2) and ends with the other edge at the lower part of the vertical fixed side guide (24). The system is ready to be used.
(25) Alternatively, the wire rope may have one edge fastened to the upper detachable edge (42) of the retention guide (2), runs horizontally the upper fixed horizontal guide and continues in exactly the same way, as described in detail in the previous paragraph.
(26) FIG. 2 illustrates the application of the autonomous anti-mosquito system with the one-sided operating of FIG. 1, on a double leaved system with central closing. In this application both systems are fixed on the same frame, opposite to each other and move, with their moving side, towards each other. Each system has a retention case (2, 50) by which it is fastened on the frame and one sliding case (1, 41) the moves and folds/unfolds the net. The retention case (50) has a detachable lower end (44a). The leaves move towards each other, the anti-mosquito nets (7, 7a) are unfolded; the two sliding cases (1, 41) meet at the center of the opening and the double leaved central system closes. The function of the double leaved central system is the same with that of the one-sided opening system described above and illustrated in FIG. 1, incorporating the same invention idea, changing only the component in which the ropes and the wire rope end, as the two-leaf central system does not have a vertical side guide at which the ropes and the wire rope stop, therefore they stop when the two sliding cases (1, 41) meet at the center of the opening. Thus, the nets (7, 7 a) again each one are run horizontally by six retention ropes (1a, 2a, 3a, 4a, 5a, 6a and 1b, 2b, 3b, 4b, 5b, 6b) all placed horizontally and in equally spaced one from another, with common starting point the trucks (21, 21a) at the side of the net (7, 7a) which is fixed in the retention case (2, 50). The ropes run along the nets (7, 7a) horizontally and parallel to each other, end to trucks (20, 20a) to the opposite side of the net (7, 7a), which is fasted in the sliding case (1, 41), pass through the trucks (20, 20a) and are directed all together as a bundle upwards, to the detachable upper edge (22, 22a) of the sliding case (1, 41) in which there are two pulleys, the first (23, 23a) above the second (28, 28a). The second pulley (28a) is mounted in block (46a).
(27) The two rope bundles (1a, 2a, 3a, 4a, 5a, 6a and 1b, 2b, 3b, 4b, 5b, 6b) run around the upper (23, 23a) pulley of each leaf, cross horizontally the upper fixed horizontal guide (25) and reach the center of the opening at a ropes' central run component (47), exactly as the one-side opening described above and illustrated in FIG. 1. The ropes' central run component (47) is fastened on the upper fixed horizontal guide (25) inside a socket (57) (drawings 6, 8, and 10). The run component (47) (FIGS. 6a and 6b) has two through openings (48, 48a). The ropes (1a, 2a, 3a, 4a, 5a, 6a) of the first leaf come from the one side of the run component (47) and as a bundle pass through the opening (48), from downwards to upwards (FIG. 10a), invert their movement and continue, inside the upper fixed guide (25) towards the retention case (2) from where they started and end to the tension adjuster (49) (FIGS. 8a and 8b), also fixed on the upper fixed horizontal guide (25), inside the socket (57) in the same line with the ropes' central run component (47). In the exactly same way, the ropes (1a, 2a, 3a, 4a, 5a, 6a) of the second leaf come from the other side of the run component (47) and pass as a bundle from the other opening (48a), from downwards to upwards, invert their movement and continue inside the upper fixed guide (25) towards the retention case (50) from where they stared and end at the tension adjuster (49a) also fastened on the upper fixed horizontal guide (25) inside the socket (57) in the same line with the ropes' central run component (47).
(28) At the same time, the edge of each wire rope (43, 43a) is fastened at the two first upper trucks (21, 21a), where the upper ropes are fastened (6a, 6b) (FIG. 2). The wire rope (43) begins from the truck (21) of the first net (7) upwards, passes through the opening of the upper part of the detachable upper end (42) of the retention guide (2), the opening is above the net (7), then it crosses the upper fixed horizontal guide (25) horizontally above the net (7) without touching it, having the same direction with that of the net unfolding, it passes through the second pulley (28) inside the detachable upper edge (22) of the sliding case (1) and above the net (7), continues vertically towards the lower fixed horizontal guide (17), goes around the pulley (31) inside the detachable lower edge (32) of the sliding case (1). Then, it continues through the lower fixed horizontal guide (17) towards its center and are fixed on a ropes' central end component (51) screwed in the middle of the lower fixed horizontal guide (17) (FIGS. 11a, 11b, 12a and 12b). The retention case (2) has a detachable lower end (44). Similarly, the wire rope (43a) of the other leaf starts from the truck (21a) of the second net (7a) upwards, passes from the opening of the upper part of the detachable upper part (42a) of the retention guide (50), the opening is above the net (7a), crosses the upper fixed horizontal guide (25) horizontally above the net (7a) without touching it, having the same direction with that of the net folding, then passes through the second pulley (28a) inside the detachable upper edge (22a) of the sliding case (41) and above the net (7a), continues vertically towards the lower fixed horizontal guide (17), passes around the pulley (31a) inside the detachable lower edge (32a) of the sliding case (41). Then through the lower fixed horizontal guide (17) it continues to its center and is also fastened at the ropes' central end component (51).
(29) As illustrated in FIGS. 11a, 11b, 12a, 12b, 13a, 13b, and 13c, the lower end component (51) consists of a plastic H-shaped component (26) and a plastic protective cap (56). The H-shaped plastic component (26) has a central fastening hole (36), two tension holes (52) of the wire ropes and two holes (54) through which the wire ropes pass. The plastic component (26) is pulled inside the socket of the lower horizontal guide (17) and is fastened in the center of the guide (17) with a screw (53) and a nut (53 a) from the central fastening hole (36). The two wire ropes (43, 43a) enter upwards from both holes (54) and are fastened with screws (55) and nuts (55a) at the two tension holes (52). The ropes' lower end component (51) has rails for the sliding cases that enter and are fastened inside it.
(30) The system is ready to be used.
(31) As illustrated in FIG. 3, the system can function in exactly the same way as a one-leave system with a two-sided opening, without requiring a retention guide, with only two fixed side guides (24, 24a) and two sliding cases (1, 41). In this type of the system, a set of ropes (1a, 2a, 3a, 4a, 5a, 6a) and two wire ropes (43, 43a) are used. In particular, all the ropes (29a, 2a, 3a, 4a, 5a, 6a) have a common starting point for the adjustor (27a) at the upper part of the vertical fixed side guide (24a). They pass through the opening of the upper detachable end (38a) of the vertical fixed side guide (24a), then as a bundle they continue round the upper pulley (23a) inside the upper detachable end (22a) of the sliding guide (41), go down in the sliding guide (41) and each passes through the truck (21) of the net (7). Then, just as in the system described above with reference to FIG. 1, the ropes run the net (7) horizontally in a position parallel to each other, ending on the opposite side of the net (7) into trucks (20) fixed inside the sliding case (1), they pass through the trucks (20) and directed upwards toward the removable upper end (22) of the sliding case (1) in which there are two pulleys, the first (23) above the second (28). The six retention ropes (1a, 2a, 3a, 4a, 5a, 6a) pass around the upper pulley (23), run horizontally the upper fixed horizontal guide (25), toward the vertical fixed side (24), pass through the opening of the upper detachable end (38) of the vertical fixed side guide (24), go downwards and are fastened to an adjuster (27) inside the upper part of the vertical fixed side guide (24).
(32) Two wire ropes are used at the one-leaf system with two-sided opening. The two wire ropes (43, 43a) are fitted opposite, that is, one (43) starts from the upper part of the right fixed side guide (24a) and ends at the lower part (29) of the left fixed side guide (24) and the other one (43a) just opposite, that is, it starts from the upper part of the left fixed side guide (24) and ends at the lower part (29a) of the right fixed side guide (24a), whereas both pass above the net. More specifically, one wire rope (43) is fastened with one edge at the upper part of the right vertical fixed side guide (24a). The wire rope passes upwards through the opening of the side guide (24a), which is above the net (7), and then with exactly the same way as in the system described above with reference to FIG. 1, is crosses the upper fixed horizontal guide (25) horizontally, always above the net (7) without coming into contact with it, with a direction the same with that of the direction of unfolding the net, it passes the net (7), then passes through the second pulley (28) inside the detachable upper edge (22) of the left sliding case (1), continues downwards to the lower fixed horizontal guide (17), continues around the pulley (31) inside the detachable lower end (32) of the sliding case (1). Then it continues through the horizontal guide (17) towards the detachable lower edge (35) with an opening, of the fixed vertical side guide (24), passes through the opening of the lower edge (35) and goes upwards and is fastened at an adjuster (29) at the lower part of the left vertical fixed side guide (24).
(33) The second wire rope (43a) follows a reverse course, is fastened with one edge at the upper part of the left vertical fixed side guide (24). The wire rope passes upwards through the opening of the side guide (24) which is above the net (7), and then in exactly the same way, as the system described above with reference to FIG. 1, follows the reverse course of the first wire rope (43), that is, crosses the upper fixed horizontal guide (25) horizontally always above the height of the net without coming into contact with it, having the same direction with that of the unfolding of the net, passes by the net (7), then passes through the second pulley (28 a) inside the detachable upper edge (22a) of the right sliding case (41), continues vertically downwards to the fixed horizontal guide (17), continues round the pulley (31a) inside the detachable lower part (32a) of the right sliding case (41). Then it continues through the horizontal guide (17) to the detachable lower edge (35a) with opening of the fixed right side guide (24a), passes from the opening of the lower edge (35a) and goes upwards and is fastened at an adjuster (29a) at the lower part of the right vertical fixed side guide (24a).
(34) The system is ready to be used.
(35) As illustrated in FIG. 4, the system may operate with exactly the same way, as a two-leaved system with openings on both sides, without retention guides (2, 50), only with two fixed side guides (24, 24a) and four sliding cases (1, 41 and 1-b, 41b) two for each leaf. In this type of the system, two rope sets are used (1a, 2a, 3a, 4a, 5a, 6a and 1b, 2b, 3b, 4b, 5b, 6b) and four wire ropes (43, 43a, 43b, 43c), of which two (43a and 43c) begin from the upper part of the left side guide (24) and one (43a) passes above the left leaf (7) and is fastened at the lower guide (17), whereas the other one (43c) passes above both leaves (7, 7a) and is fastened at the left side guide (24). Similarly, the other two wire ropes (43, 43b) begin from the upper part of the right side guide (24a), one of which (43b) passes above the right leaf (7a) and is fastened at the lower guide (17), whereas the other (43) passes above both leaves (7a, 7) and is fastened at the right side guide (24a). At the center of the opening, there are run/end components for the ropes—upper (47, 49, 49a) and lower (51) screwed at the upper (25) and lower (17) horizontal guide. At this two-leaved system with openings from both sides, each leaf functions independently within the system.
(36) More particularly, exactly as in the system described above with reference to FIG. 3 of the one-leaf system with opening on both sides, at this two-leafed system all ropes (1a, 2a, 3a, 4a, 5a, 6a) of the leaf (7) have a common starting point for the adjuster (27) at the upper part of the vertical fixed side guide (24). They pass through the opening of the upper detachable edge (38) of the vertical fixed side guide (24), pass horizontally as a bundle through the upper pulley (23) inside the upper detachable edge (22) of the sliding case (1), move downwards into the sliding case (1) and each goes to one truck (20) of the net (7) of the first leaf. There is a central closing, exactly in the way described above with reference to FIG. 2. That is, the ropes cross the net (7) horizontally and in a parallel to each other, end at the opposite side of the net (7) at trucks (21) fixed inside the opposite sliding case (41), pass through the trucks (21) and continue upwards to the detachable upper edge (22a) of the sliding case (41) within which there are two pulleys, the first (23a) above the second (28a). The six retention ropes (1a, 2a, 3a, 4a, 5a, 6a) pass around the pulley (23a), cross horizontally the upper fixed horizontal guide (25) towards the central closing and reach the center of the opening at a central component through which the ropes pass (47) (FIGS. 4, 6a, 6b, 10a, 10b, 10c, and 10d). The ropes (1a, 2a, 3a, 4a, 5a, 6a) of the first leaf reach from one side of the run component (47) and pass as a bundle through the opening (48) upwards, reverse their course continuing inside the upper fixed guide (25) directed towards the retention case (24) from where they started and end at a tension adjuster (49 a) fixed also on the upper fixed horizontal guide (25). The couples of pulleys of each leaf (couples 23, 23a) and through which the ropes pass, are at the same height; similarly, the other couple of pulleys (28, 28a) through which the wire rope passes.
(37) As in the one-leaf system with opening from both sides described above with reference to FIG. 3, also at the two-leaf system (FIG. 4) one wire rope (43) is fastened at one end to the upper part of the right vertical side guide (24a), it starts at the upper part of the right fixed side guide (24a) and ends at the lower part (29) of the left fixed side guide (24). In particular, the rope passes upwards through an opening of the side guide (24a) which is above the height of the nets (7, 7a), and then in exactly the same way as in the system described above in detail with reference to FIGS. 1, 2 and 3, it crosses the upper fixed horizontal guide (25) horizontally, always above the height of the two nets (7, 7a) without coming into contact with them, it passes through the nets, then it passes through the second pulley (28) inside the detachable upper edge (22) of the left sliding case (1) of the second leaf (17), continues upwards to the lower fixed horizontal case (17), goes around the pulley (31) inside the detachable lower edge (32) of the sliding cases (1) of the second leaf (7), then it continues through the horizontal guide (17) to the detachable lower end (35) with an opening of the fixed vertical guide (24), passes through the opening of the lower edge (35), goes upwards and is fastened to an adjuster (29) at the lower part of the left vertical fixed side guide (24).
(38) The second wire rope (43a) is placed exactly opposite, that is, it begins from the upper part of the left fixed side guide (24), encircles the first leaf (7) and ends and is fastened at the ropes' central end component (51) at the lower fixed guide (17). In particular, the wire rope (43a) is fastened with one end at the upper part of the left vertical fixed side guide (24). Going upwards, the wire rope passes through the opening of the side guide (24), which is above the net (7) and then, in the exactly same way as in the system described above with reference to FIG. 1, it crosses the upper fixed horizontal guide (25) horizontally, always above the net (7) without coming into contact with it, it passes by the net (7), then passes through the second pulley (28a) inside the detachable upper edge (22a) of the right sliding case (41), continues vertically to the lower fixed horizontal guide (17), goes around the pulley (31 a) inside the detachable lower edge (32a) of the right sliding case (41). Then it continues through the lower horizontal guide (17) to its center and is fastened at a ropes' central end component (51) that is screwed in the middle of the lower horizontal guide (17) (FIGS. 4, 11a, 11b, 12a, and 12b).
(39) The second leaf (7 a) functions exactly in the same way, having all components opposite and symmetrical to the components of the first leaf. All ropes (1b, 2b, 3b, 4b, 5b, 6b) of the leaf (7a) have a common starting point for the adjuster (27a) at the upper part of the vertical fixed side guide (24a). They pass from the opening of the upper detachable edge (38b) of the vertical fixed side guide (24a), pass as a bundle from the upper pulley (23c) inside the upper detachable edge (22c) of the sliding guide (41b), continue vertically inside the sliding guide (1-b) and each goes to a truck (20a) of the net (7a) of the second leaf. Then, exactly as in the system of the first leaf, the ropes run the net (7a) horizontally and parallel to each other, end at the opposite side of the net (7a) at trucks (21a) fixed inside the sliding case (41b), pass through the trucks (21a) and go upwards to the detachable upper edge (22b) of the sliding case (41b) in which there are two pulleys, the first (23b) above the second (28b). The six retention ropes (1b, 2b, 3b, 4b, 5b, 6b) pass as a bundle around the upper (23b) pulley, cross horizontally the upper fixed horizontal guide (25) towards the central closing and reach the center of the opening at a central run component (47) (FIGS. 4, 6a, 6b, 10a, 10b, 10c, and 10d). The ropes (1b, 2b, 3b, 4b, 5b, 6b) of the second leaf that come from the opposite side of the run component (47) of the ropes (1a, 2a, 3a, 4a, 5a, 6a) of the first leaf and pass as a bundle the second opening (48a) upwards, reverse their course, continuing always inside the upper fixed guide (25) towards the retention case (24a) from where they started and end at a tension adjuster (49) that is also fixed on the upper fixed horizontal guide (25).
(40) The third wire rope (43c) is placed in a similar way with the first wire rope (43) of the first leaf, exactly opposite and symmetrical thereto. In particular, it is fastened with one edge at the upper part of the left vertical fixed side guide (24). Continuing upwards, the wire rope (43c) passes from the opening of the side guide (24) which is above the nets (7, 7a) and then, in exactly the same way as the system of the first leaf, it crosses the upper fixed horizontal guide (25) horizontally, always above the two nets (7, 7a) without coming into contact with them, then passes through the second pulley (28c) inside the detachable upper edge (22c) of the right sliding guide (1-b) of the second leaf (7a), continues vertically to the lower fixed horizontal guide (17), goes around the pulley (31c) inside the detachable lower edge (32c) of the sliding case (1-b). Then it continues through the horizontal guide (17) towards the detachable lower edge (35b) with opening of the fixed vertical side guide (24a), passes through the opening of the lower edge (35b) and continues upwards and is fastened at an adjuster (29a) at the lower part of the right vertical fixed side guide (24a).
(41) The fourth wire rope (43b) continues an opposite and symmetrical course to that of the wire rope (43a) described above encircling the first leaf (7). In particular, the fourth wire rope (43b) is fixed with one edge at the upper part of the right vertical fixed side guide (24a). Going upwards, the wire rope (43b) passes through the opening of the side guide (24a) which is above the height of the net (7a) and then, in exactly the same way as in the first leaf described above, it crosses the upper fixed horizontal guide (25) horizontally, always above the net (7a) without coming into contact with it, it passes by the net (7a), then passes through the second pulley (23a) inside the detachable upper edge (22b) of the left sliding case (41b), continues vertically to the lower fixed horizontal guide (17), goes around the pulley (31b) inside the detachable lower edge (32b) of the left sliding case (41b), continues through the horizontal guide (17) to its center and is fastened at a ropes' central end component (51) screwed in the middle of the lower fixed horizontal guide (17) (FIGS. 4, 11a, 11b, 12a, and 12b), exactly from the other side of the end component (51) where the opposite wire rope (43a) of the system ended.
(42) The system is ready to be used.
(43) Finally, as illustrated in FIG. 5, the system can function in exactly the same way as a three-leaf system with openings from both sides. In this type, the system functions as follows: the two side leaves function exactly in the same way that was described above with reference to FIG. 4. A third leaf (7b) is placed between them (FIG. 5), but with the mode described more independent leaves may be placed, making the system four-leaved, five-leaved, etc, thus allowing the closing of a wide opening. In particular, the in-between leaf (7b) has two sliding guides (43 d, 43 e) at both sides and has its own rope set (le, 2e, 3e, 4e, 5e, 6e). At both sides of the leaf, upper and lower, screwed at the upper (25) and lower (17) horizontal guide, there are run/end rope components (47, 47b), tightening pulleys (68, 68a) and lower end components (51, 51b) at the point where the sliding guides of the leaves end and meet.
(44) The function of the in-between leaf (7b), as that of each additional in-between leaf, is as follows: All ropes (le, 2e, 3e, 4e, 5e, 6e) of the leaf (7b) run the net (7b) horizontally and parallel to each other, passing through the trucks (20c and 21c) that the net has at its edges. Then with both ends they continue as bundles upwards to the two detachable upper edges (22d and 22e) of the two sliding guides (43d and 43e). Inside each edge (22d and 22e) there are two pulleys (23d, 28d and 23e, 28e). They pass as bundles through both pulleys (23d and 23e), cross horizontally the upper fixed horizontal guide (25) towards each one the ropes' central run component (47 and 47b) being closer to it (FIGS. 5, 6a, 6b, 10a, 10b, 10c, and 10d). Each bundle passes through the openings (48d and 48) of each central component, upwards, reverse their course continuing always inside the upper fixed guide (25) with return direction towards the leaf (7b) and end at the tension adjusters (68, 68a) also fixed on the upper fixed horizontal guide (25).
(45) The two wire ropes (43d, 43e) of the in-between leaf (7b) start each one from the vertical side guides (24a, 24) and end at the lower end component (51, 51b). In particular, the first wire rope (43d) is fixed with one edge at the upper part of the right vertical fixed side guide (24a). Going upwards, the wire rope passes through the opening of the side guide (24a) that is at a height above all nets, crosses the upper fixed horizontal guide (25) horizontally, always above the nets, passes by the net (7b) without coming into contact with it, then passes through the second pulley (28d) inside the detachable upper edge (22d) of the left sliding case (43d), continues vertically towards the lower fixed horizontal guide (17), passes round the pulley (31d) inside the detachable lower edge (32d) of the left sliding case (43d). Then, it continues through the horizontal guide (17) at the ropes' lower end component (51) that is screwed at the lower fixed horizontal guide (17) and is fastened there (FIGS. 5, 11a, 11b, 12a, 12b).
(46) The second wire rope (43e) is fastened with one edge at the upper part of the left vertical fixed side guide (24). Going upwards, the wire rope passes through the opening of the side guide (24) which is at a height above all nets, crosses the upper fixed horizontal guide (25) horizontally, always above the height of the nets, passes by the net (7b) without coming into contact with it, then passes through the second pulley (28e) inside the detachable upper edge (22e) of the right sliding case (43e), continues vertically towards the lower fixed horizontal guide (17), passes around the pulley (31e) inside the detachable lower edge (32e) of the right sliding case (43e). Then, it continues through the horizontal guide (17) to the ropes' lower central end component (51b) that is screwed at the lower fixed horizontal guide (17), where it is fastened (FIGS. 4, 11a, 11b, 12a, and 12b).
(47) FIGS. 6a, 6b, 7a, 7b, 7c, 7d, 8a, 8b, 9a, 9b, 9c, 9d, 10a, 10b, 10c, and 10d illustrate the mode by which the central ropes' run component (47) and the two tension adjusters (49) are fastened inside the upper fixed guide (25). The ropes' central run component (47) (FIGS. 6a, 6b, 7a, 7b, 7c, 7d) has two through square openings (48, 48a) and in the middle a through hole (58), through which a screw (59) passes from the lower part of the component and on which a rhomboid butterfly (60) is screwed. The butterfly nut (60) has two sides (A, B) larger than the other two (C, D), where the two smaller sides (C, D) have a smaller width than the width of the receptor (57) that the upper fixed guide (25) has, inside which the run component (47) will be stabilized. The component also has on its upper surface four mountings (65) and two parallel mountings (67) along its edges (FIGS. 6a and 6b).
(48) Each tension adjuster (49) (FIGS. 8a, 8b, 9a, 9b, 9c, and 9d) has a square through hole (61) and a through hole (62), through which a screw (63) passes from the lower part of the stretcher and on which a rhomboid butterfly nut is screwed (60). The butterfly nut (60) has two sides (A, B) larger than the other two (C, D), where the two smaller sides (C, D) have a smaller width than the width of the receptor (57) that the upper fixed guide (25) has, inside which the stretcher will be stabilized. The stretcher has on its upper surface two mountings (64) (FIGS. 8a and 8b).
(49) All three components for the fastening of the ropes, the ropes' central run component (47) and the two tension adjusters (49) are placed all three inside the upper horizontal fixed guide (25) in the following mode (FIGS. 7a, 7b, 7c, 7d, 9a, 9b, 9c, and 9d):
(50) The ropes' central run component (47) (FIG. 7) enters the upper guide (25) upwards, inside the socket (57) of the guide (25) (FIGS. 7a, 7b). The rhomboid butterfly nut (60) enters the socket (57) having its largest sides (A, B) parallel to the mountings (67) of the component. The parallel mountings (67) enter the respective grooves (66) of the upper guide (25) (FIG. 7c). By using a tool, such as an Allen, the screw is screwed (59) while the butterfly nut (60) turn and the whole run component (47) is stabilized in the socket (57) of the upper guide (25) (FIG. 7c, 7d).
(51) Each tension adjuster (49) enters the upper guide (25) upwards, inside the socket (57) of the guide (25). The rhomboid butterfly nut (60) enters the socket (57) having the large sides (A, B) in a straight line with the mountings (64) (FIGS. 9a, 9b, 9c, and 9d). The butterfly nut (60) enters the socket (57) of the guide (FIG. 9c). By using a tool, such as an Allen, the screw is screwed (59) while the butterfly nut (60) turn and the whole run component (49) is stabilized in the socket (57) of the upper guide (25) (FIG. 9c, 9d).
(52) FIGS. 10a, 10b, 10c, and 10d illustrate the connection of the ropes with the three ropes' stabilization components: ropes' central run component (47) and two tension adjusters (49). After the ropes having passed through the three components and having stabilized in them (FIG. 10a), then, as described above, first the central ropes' run component (47) and then the two stretchers on both sides (FIGS. 10b, 10c) enter inside the socket (57) of the upper guide (25) and are fastened. Thus, the ropes are stretched as much as needed.
(53) The ropes' central end component (51) is at the same vertical line with the ropes' run component (47). The sliding guides enter and stop inside the grooves of the ropes' central end component (51) and the run component (47).
(54) The ropes' central end components (51), the tension adjusters (49) and the run component (47) function all together, never in an autonomous way.
(55) As illustrated in FIGS. 14a and 14b, the autonomous anti-mosquito system with the one-sided opening of FIG. 1, is semi-assemblies as a kit (FIG. 14a) and after being cut at dimensions equal to the height of the opening, it is assembled on the spot (FIG. 14b).
(56) The invention functions exactly in the same way if instead of a wire rope another strong rope is used.
(57) The invention is implemented on all anti-mosquito nets with pleated net and horizontal movement and have a fixed horizontal guide at the bottom.
