- The frame of Fig.1 comprises a first
roller shutter box 1 which houses a vertical take-up roller 2 and a secondroller shutter box 3 wherein ashaft 4 runs. A firstelastic mechanism 5, housed in the firstroller shutter box 1, is used for rotating the take-up roller 2, while a second elastic mechanism 6 inside the secondroller shutter box 3 is capable of rotating theshaft 4. - The take-
up roller 2, stressed by theelastic mechanism 5, stretches a blind 7 (mosquito net or sunscreen) capable of closing a French window; the blind 7 is drawn between the take-up roller 2 and amanoeuvring bar 8 kept in vertical position on twosliding guides - A
pulley 11, (12) is splined to both ends of theshaft 4 for manoeuvring a respectiveflexible tie rod 13, (14), the free end of which is connected to themanoeuvring bar 8. Thetie rods respective guides manoeuvring bar 8; this stress prevails on the stress of the firstelastic mechanism 5 transmitted to thebar 8 by the blind 7, therefore the blind 7 closes the French window when only the stresses of bothelastic mechanisms 5, 6 are applied to the blind 7. - In Fig.2 the blind 7 is partially open as a consequence of a shifting to the left of the
manoeuvring bar 8 due to an external force (i. e. a hand) applied to ahandle 15 of thebar 8. - In Fig.3 the blind 7 is completely open as a consequence of a further shifting to the left of the
manoeuvring bar 8 due to an external force applied to thehandle 15 of thebar 8. In this Figure theguides bar 8 and thetie rods - The stress shifting the
manoeuvring bar 8 to the left is stronger than the one of the second elastic mechanism 6 because it must overcome the tensile stress of thetie rods bar 8. The rolling of the blind 7 over the take-uproller 2 is effected by the firstelastic mechanism 5, which stretches the blind 7 as it shifts to the left or to the right. - When the configuration of Fig.3 is reached, the
bar 8 is released for automatically restoring the position of Fig.1 of the blind 7 and thebar 8; in fact the second elastic mechanism 6 prevails on the firstelastic mechanism 5 in order to automatically shut the French window. - As shown in Fig.4, the
manoeuvring bar 8 consists of twoseparate jambs jamb 16 connected to the blind 7 can be separated from thejamb 17 on which thetie rods - By means of this configuration of the
manoeuvring bar 8 it is possible to maintain the French window open to allow a piece of furniture or other cumbersome item to pass through. It is evident that when thejambs roller 2 because of no stress opposing the rolling stress of thefirst mechanism 5; therefore, thetie rods respective pulleys - The upper guide 9 (Fig.5) consists of two
channels external channel 18 houses aninternal channel 19 representing the real guide of themanoeuvring bar 8; for better understanding the position of bothjambs manoeuvring bar 8 shown in this Figure, a section is practiced in connection with said position. The blind 7 is constrained by thejamb 16, while the tie rod 13 (14) is jointed to thejamb 17; bothjambs bar 8 slide inside thechannel 19; the blind 7 is stretched by the take-uproller 2. - The

Theupper bracket 26 is found over therib 28 of theinternal guiding channel 19, while thelower bracket 27 is located underneath; the twobrackets rib 28 at the respective end of the guidingchannel 19. - Figs 13, 14 show the
upper guide 9 and the upper part of the take-uproller 2; the scales of these Figures have been chosen in order to highlight the configuration of the illustrated mechanical elements, therefore they are not necessarily faithful to the actual dimensions of said elements. Theupper guide 9 is connected to anexternal housing 29 of the roller shutter box 1 (3); in particular, theexternal channel 18 is fastened to acap 30 closing the upper part of the roller shutter box 1 (3). Thecap 30 presents a supportingrod 31 on which theexternal channel 18 of theupper guide 9 rests; acover 32 protecting the take-up roller 2 (and the shaft 4) is fitted with abracket 33 forming the sliding bearing of thetube 24 of the connectingelement 23.

upper guide 19 works in case the frame is not duly mounted or protects a French window with an incorrectly levelled cornice. - If duly mounted in a correctly levelled window (o French window), the frame is set as in Fig.18; the
upper guide 19 is supported by two supportingbrackets manoeuvring bar 8 with respect to the ends of theguides brackets upper guide 19 parallel to thelower guide 10, while themanoeuvring bar 8 can easily slide in both translation directions to open or close the room protected by the blind 7. In this condition theupper guide 19 is constrained by both supportingbrackets - If the constraints of the
guides 19 are stiff and the frame is incorrectly mounted or is found in an incorrectly levelled window, theguides manoeuvring bar 8 will not be capable of sliding. - According to the invention the guiding
channel 19 is free to vertically translate together with the connectingelements 23 inside thelongitudinal opening 34 of theexternal channel 18; this feature allows an easy displacing of themanoeuvring bar 8 even in case of incorrect mounting of the frame on an incorrectly levelled cornice. - If the
bracket 33a (Figs 19, 20) is mounted lower than due, the displacement of themanoeuvring bar 8 to the opening position of the blind causes a relative rising of theupper guide 19 with respect to thelower guide 10; on the contrary, if thebracket 33b (Figs 21, 22) is mounted lower than due, the displacement of themanoeuvring bar 8 to the closing position causes a relative rising of theupper guide 19 with respect to thelower guide 10; both displacements allow theupper guide 19 to set parallel to thelower guide 10. - In a not shown embodiment the
external channel 18 is constrained to a structure external to the frame (for example, a wall) in correspondence with the same by means of fixing means (i. e. screws, nails, brackets, etc.).

the frame further comprising:a first roller shutter box (1) housing a take-up roller (2) for the blind (7), and a second roller shutter box (3), in which a shaft (4) turns;the manoeuvring bar (8) being connected to the take-up roller (2) by the blind (7) and to the shaft (4) through driving elements (11,12,13,14);a first spring loaded mechanism (5) being housed in the first roller shutter box (1); the first spring loaded mechanism (5) being capable of rotating the take-up roller (2); a second spring loaded mechanism (6) being located in the second roller shutter box (3), the second spring loaded mechanism (6) being capable of rotating the shaft (4); when no external force is applied to the vertical manoeuvring bar (8) of the blind (7), the force of the second spring loaded mechanism (6) applied to the manoeuvring bar (8) via the driving elements (11,12,13,14) is stronger than the force of the first spring loaded mechanism (5) transmitted to the manoeuvring bar (8) by the blind (7), so that the blind (7) closes the window opening;supporting means (33a,33b) are provided to constrain the upper guide (9) to the frame, said supporting means (33a,33b) being capable of allowing displacements of the upper guide (9) in order to maintain the upper guide (9) parallel to the lower guide (10) for each position of the manoeuvring bar (8) with respect to the ends of the upper and lower guides (9,10). - Roller blind as in claim 1, wherein the manoeuvring bar consists of two separable jambs (16,17).
- Frame as in claim 1, wherein the upper guide (9) consists of two channels (18,19); an external channel (18) housing an internal channel (19) representing the real guide of the manoeuvring bar (8); the external channel (18) being shaped like a reversed U defining a longitudinal opening (34); the internal channel (19) being located inside the opening (34) shaped like a reversed C and having two symmetrical recesses (20,21), said recesses (20,21) delimiting a longitudinal groove (22) in which the manoeuvring bar (8) can slide.
- Frame as in claim 3, wherein the internal channel (19) is free to vertically translate inside the longitudinal opening (34) of the external channel (18) to allow an easy displacement of the manoeuvring bar (8) even in the case of an incorrect montage of the frame on an incorrectly levelled window opening.
- Frame as in claim 1, wherein the supporting means (33a,33b) consist of brackets (33) integral with covers (32) which protect the take-up roller (2) and the shaft (4), the internal channel (19) freely resting on said brackets (33).
- Frame as in claim 5, wherein two respective connecting elements (23) are provided at both ends of the upper guide (9), each of said connecting elements (23) consisting of a tube-like structure (24) connected to a longitudinal slit (25); two brackets (26,27) constrain the connecting element (23) to the respective end of the internal channel (19), the upper bracket (26) is located over a rib (28) of the internal channel (19), while the lower bracket (27) is located underneath; the two brackets (26,27) embracing the rib (28) at the respective end of the internal channel (19).
- Frame as in claim 1, wherein the lower guide (10) further presents a longitudinal internal groove (42), the groove (42) being capable of housing a slide (40) integral with a first jamb (16) of the manoeuvring bar (8), the first jamb (16) being connected to the blind (7); the slide (40) having an analogous form to the form of the groove (42) for preventing the slide (40) from coming out of the groove (42) during translations of the bar (8).
- Frame as in claim 7, wherein said first jamb (16) presents a housing (35) for a roller (36) having an arched shape (38), the radius of curvature of which is equal to the radius of curvature of the upper edge (39) of the lower guide (10).
- Frame as in claim 7, wherein a second jamb (17) of the manoeuvring bar (8) connected to the shaft (4) presents a frontal slide (41) fitted with brushes, the frontal slide (41) sliding on the lower guide (10); said frontal slide (41) further presenting a radius of curvature equal to the radius of curvature of the upper edge (39) of the lower guide (10).
- Frame as in claim 9, wherein the second jamb (17) of the manoeuvring bar (8) connected to the shaft (4) has a longitudinal dimension smaller than the longitudinal dimension of the first jamb (16) connected to the blind (7).
