Description

DOMAINE TECHNIQUE DE L'INVENTION

[0001] The present invention relates to the field of construction, and more particularly concerns a window or French window with first and second sliding openings.

[0002] A window or French window with first and second openings arranged to slide in a sliding direction is known, the first and second openings respectively comprising a first and a second upright extending respectively in a first longitudinal direction and a second longitudinal direction, said first and second uprights being intended to come into correspondence with each other to form a central window or French window upright when the first and second openings are in the closed position in which they have the smallest mutual overlap, said first and second openings being carried by rolling means allowing them to slide.

[0003] Document FR 2 810 066 A1 describes on its figure 12 a window or French window according to the preamble of claim 1.

[0004] To ensure a seal at the central upright, this document provides a seal arranged to be inserted between the first and second uprights when the first and second openings are in the closed position.

[0005] When the openings are brought into the closed position, the seal generally closes (with a slight clearance) the gap between the first and second uprights. The seal can sometimes even be slightly compressed between the first and second uprights. The seal obtained between the first and second uprights remains unsatisfactory, however, particularly in windy conditions.

[0006] To improve the sealing of a window or similar patio door, it has been proposed: rolling means carrying the first opening and allowing movement of the first opening transversely to the sliding direction, transverse movement means capable of causing relative movement of the first opening transversely to the sliding direction.

[0007] Such a window or French window is, for example, marketed by Roto Frank Fenster- und Türtechnologie GmbH under the registered trademark "Roto Patio Inowa". The transverse displacement of the first sash allows for better compression of the seal between the first and second uprights. However, the second sash is fixed (not sliding), which is very restrictive in use, and the hardware includes complex, bulky and expensive components. EXPOSE DE L'INVENTION

[0008] A problem addressed by the present invention is to provide a window or French window with first and second sliding openings having improved sealing at its central upright.

[0009] At the same time, the invention aims to provide such a window or French window whose openings can be manipulated in any order, without risk of damage.

[0010] According to another aspect, the invention aims to provide such a window or French window with inexpensive, compact hardware that is easy to integrate into the openings.

[0011] To achieve these and other objects, the invention provides a window or French window according to claim 1.

[0012] In the initial state, the first and second opening leaves are in the closed position. The first and second locking members are in the locked position. The first and second locking members are then supported in the transverse direction by means of their respective first and second support surfaces which thus hold the opening leaves at a first distance from each other in the transverse direction.

[0013] When a user begins to manipulate the first opening, for example using a rotary handle carried by the first opening, the first locking member is moved to its release position. The first bearing surface is then moved away from the second bearing surface. The first upright can then be moved away in the transverse direction from the second upright (for example by the seal elastically returning to its pre-compression shape and / or by a spreading force induced by the user on the first opening), to be arranged at a second distance (greater than the first distance) from the second upright, then the first opening can be slid relative to the second opening in the sliding direction.

[0014] When the user wishes to close the window or French window, he brings the first opening leaf back so as to place the first and second opening leaves in the closed position. The first and second bearing surfaces are then in correspondence with each other in a direction parallel to the first or second longitudinal direction. The user then applies a reverse maneuver to the first opening leaf, for example using the rotary handle carried by the first opening leaf, to move the first locking member to its locking position. During this movement, the first bearing surface comes to bear against the second bearing surface, and the movement of the first locking member to its locking position produces a relative approximation of the first and second uprights in the transverse direction, once again ensuring the compression of the seal between the two uprights to guarantee a good seal.

[0015] When a user begins to manipulate the second opening, for example using a rotary handle carried by the second opening, the second locking member is moved to its release position. The second bearing surface is then moved away from the first bearing surface. The second upright can then be moved away in the transverse direction from the first upright (for example by the seal elastically returning to its pre-compression shape and / or by a spreading force induced by the user on the second opening), to be arranged at a second distance (greater than the first distance) from the first upright, then the second opening can be slid relative to the first opening in the sliding direction.

[0016] When the user wishes to close the window or French window, he brings the second opening leaf back so as to place the first and second opening leaves in the closed position. The first and second bearing surfaces are then in correspondence with each other in a direction parallel to the first or second longitudinal direction. The user then applies a reverse maneuver to the second opening leaf, for example using the rotary handle carried by the second opening leaf, to move the second locking member to its locking position. During this movement, the second bearing surface comes to bear against the first bearing surface, and the movement of the second locking member into its locking position produces a relative approximation of the first and second uprights in the transverse direction, once again ensuring the compression of the seal between the two uprights to guarantee a good seal.

[0017] This provides a window or French window with first and second sliding sashes, with improved sealing at its central jamb, and whose sashes can be operated in any order, without risk of damage. The mechanical movements to be ensured are relatively simple, so that the hardware can be simple, compact and inexpensive.

[0018] Preferably, it can be provided that: the first bearing surface has a convexity oriented towards the first upright in the transverse direction, and / or the second bearing surface has a convexity oriented towards the second upright in the transverse direction.

[0019] The first and second support surfaces thus have shapes that are simple to manufacture and configure to obtain the desired proximity between the first and second uprights.

[0020] In practice, still for the sake of simplicity, the first and / or the second bearing surface may have, in a plane perpendicular to the sliding direction, a general V shape with a vertex between two sides generally oblique to the first or second longitudinal direction.

[0021] Advantageously, the vertex connecting the generally oblique sides may be generally flat and extend parallel to the closing plane. The flat vertex(s) make it possible to obtain a reliable and repetitive relative gap between the first and second openings when the first and second locking members are in the locking position.

[0022] To provide increased security for the window or French window against intrusions by malicious persons into a building, the first bearing surface may advantageously have, in the sliding direction, a first section of the first bearing surface and a second section of the first bearing surface connected by a step with a first bearing facet arranged so that, when the first and second locking members are in the locking position, the first bearing facet opposes a relative movement of the first and second locking members away from each other in the sliding direction.

[0023] Thus, when the first and second locking members are in the locking position, sliding of the first and second openings is prevented as long as at least one of the first and second locking members is not moved to the release position (which is done from the inside of the building, for example by means of handles carried by the first and second openings).

[0024] Symmetrically and to further improve safety, the second bearing surface may advantageously have, in the sliding direction, a first section of second bearing surface and a second section of second bearing surface connected by a step with a second bearing facet arranged so that, when the first and second locking members are in the locking position, the second bearing facet opposes a relative movement of the first and second locking members away from each other in the sliding direction.

[0025] Here again, when the first and second locking members are in the locking position, sliding of the first and second openings is prevented as long as at least one of the first and second locking members is not moved into the release position (which is done from the inside of the building, for example by means of handles carried by the first and second openings).

[0026] Preferably, the first and second locking members may have identical shapes. The openings may thus be identical for easy industrialization of the window or French window.

[0027] Preferably, it can be provided that: the movement of the first locking member between its locking and release positions is controlled by a first cremone bolt arranged in the first upright, and / or the movement of the second locking member between its locking and release positions is controlled by a second cremone bolt arranged in the second upright.

[0028] Using the first and / or second cremone bolt, most often already present on the first and second openings, is advantageous for limiting the addition of components and thus reducing the size and cost.

[0029] For a simple structure, we can advantageously provide that: the first locking member is secured to the first cremone bolt, and / or the second locking member is secured to the second cremone bolt.

[0030] To avoid any conflict between the first and second locking members when sliding the first and second openings, while the first and second locking members are in the released position, it is preferably possible to provide that: the first locking member is moved between its locking and release positions according to a first stroke, the second locking member is moved between its locking and release positions according to a second stroke, the first and second strokes have different lengths.

[0031] For easier and more intuitive use for users, while promoting the simplicity and uniqueness of the hardware, it is advantageous to provide that: the first and second cremones are respectively actuated in movement by a first and a second rotary handles respectively carried by the first and the second opening, the first and second cremones have strokes of identical lengths for the same rotation of their rotary handle, the first locking member is arranged to slide freely on the first cremone according to a predetermined free stroke, the second locking member is fixed in translation on the second cremone.

[0032] This ensures, in a simple, reliable and effective manner, that the second locking member has a stroke, between its locking position and its release position, the length of which is necessarily different from (in this case shorter than) that of the stroke by which the first locking member must be moved between its locking position and its release position. This difference in stroke lengths is transparent to the user, who must rotate by a single angular amplitude to release one or other of the openings.

[0033] The predetermined free travel may be chosen by a person skilled in the art by taking into consideration the shapes of the first and second bearing surfaces, the relative heights of the first and second bearing surfaces in the first and second longitudinal directions, as well as the length of the travels of the first and second cremones for a predetermined rotation of the first and second rotary handles.

[0034] Preferably, the same rotation of the rotary handles, allowing the first and second locking members to be moved from their locking position to their release position, can be 180 degrees. Indeed, considering that the rotary handles are generally vertical when the openings are locked, the rotary handles can thus also be vertical when the locking members are in the release position. This limits the risks of conflict between the handle of one of the openings and the upright of the other of the openings during sliding. DESCRIPTION SOMMAIRE DES DESSINS

DESCRIPTION DES MODES DE REALISATION PREFERES

[0036] Where identical reference numerals are used in more than one embodiment or variation of the invention, such reference numerals designate identical or similar elements in each of the embodiments or variations.

[0037] On the figures 1 à 16 an embodiment of a French window 1 according to the invention is illustrated.

[0038] We see on the figures 1 And2 that the French window 1 comprises a first opening 2 and a second opening 3 arranged parallel to each other on either side of a closing plane P sliding relative to a frame 4 in respective sliding directions parallel to direction II (therefore, reference will subsequently be made to “sliding direction(s) II” for one and / or the other of the openings 2 and 3), and parallel to the closing plane P.

[0039] The first 2 and second 3 openings respectively comprise a first upright 5 and a second upright 6 extending respectively in a first longitudinal direction II-II and a second longitudinal direction III-III. The first and second longitudinal directions II-II and III-III are parallel to each other, and are in practice intended to be vertical while the sliding directions II are intended to be horizontal.

[0040] Said first 5 and second 6 uprights are intended to correspond to one another to form a central upright 7 of French window 1 when the first 2 and second 3 openings are in the closed position.

[0041] The said closing position is illustrated in the figure 2 : this is the position in which the first 2 and second 3 openings have the smallest mutual overlap. They then cooperate to close the entire opening defined by the frame 4.

[0042] To allow them to slide, the first 2 and second 3 openings are carried by rolling means 8. An example of rolling means is illustrated in the figures 3 et 4 .

[0043] On these figures 3 et 4 , it can be seen that the rolling means 8 comprise a housing 9 in which are contained two rollers 10a and 10b integral with each other and arranged to pivot relative to the housing 9 around a pivot axis IV-IV. The two rollers 10a and 10b are also arranged to slide along the pivot axis IV-IV to be movable in translation between the two longitudinal main walls 9a and 9b of the housing 9 according to a movement illustrated by the double arrow 11. The connection between the rollers 10a and 10b and the housing 9 is thus a sliding pivot of axis IV-IV.

[0044] The housing 9 is intended to be fixed under the first 2 and second 3 openings. Thanks to the translational movable nature of the rollers 10a and 10b relative to the housing 9, the rolling means 8 carrying the first 2 and second 3 openings allow a movement of the first 2 and second 3 openings in a transverse direction VV (perpendicular to the first II-II and second III-III longitudinal directions, and perpendicular to the sliding direction II). The transverse direction VV is thus perpendicular to the closing plane P.

[0045] We see more particularly on the figures 5 And 7in particular that the French window 1 comprises at least one elastically compressible seal arranged so as to be inserted between the first 5 and second 6 uprights when the first 2 and second 3 openings are in the closed position. In this case, the French window 1 comprises a first seal 12 carried by the first upright 5 and a second seal 13 carried by the second upright 6.

[0046] We see more particularly on the figure 5 that the French window 1 further comprises a first locking member 14 carried by the first upright 5 and movable by sliding along the first upright 5.

[0047] The first locking member 14 is movable in the first longitudinal direction II-II between a locking position ( figures 5 , 8 And 9 ) and a release position ( figures 11 , 12 And 16 ).

[0048] The French window 1 further comprises a second locking member 15 carried by the second upright 6 and movable by sliding along the second upright 6.

[0049] The second locking member 15 is movable in the second longitudinal direction III-III between a locking position ( figures 5 , 8 , 9 , 11 And 12 ) and a release position ( figures 14 And 16 ).

[0050] The first 14 and second 15 locking members are adapted to bear against each other according to respective first S1 and second S2 bearing surfaces shaped so that: the movement of one of the first 14 or second 15 locking members towards its locking position, when the other of the first 14 or second 15 locking members is in the locking position, causes the first 5 and second 6 uprights to move closer together in the transverse direction VV, the movement of one of the first 14 or second 15 locking members towards its release position, when the other of the first 14 or second 15 locking members is in the locking position, allows the first 5 and second 6 uprights to move away in the transverse direction VV.

[0051] We see more particularly on the figures 5 , 6 And 8 that the first 14 and second 15 locking members have identical shapes.

[0052] In more detail: the first bearing surface S1 has a convexity oriented towards the first upright 5 in the transverse direction VV, and the second bearing surface S2 has a convexity oriented towards the second upright 6 in the transverse direction VV.

[0053] The first bearing surface S1 has, in a plane P1 intended to be perpendicular to the sliding direction II, a general V shape with a vertex S10 between two sides S11 and S12 generally oblique to the first longitudinal direction II-II.

[0054] Similarly, the second bearing surface S2 has, in a plane P2 intended to be perpendicular to the sliding direction II, a general V shape with a vertex S20 between two sides S21 and S22 generally oblique to the second longitudinal direction III-III.

[0055] When the first 14 and second 15 locking members are mounted on the first 2 and second 3 openings, the planes P1 and P2 are parallel.

[0056] We observe on the figure 6 that the vertices S10 and S20 respectively connecting the generally oblique sides S11 and S12 on the one hand, S21 and S22 on the other hand, are generally flat and extend parallel to the closing plane P. The generally oblique sides S11, S12, S21 and S22 are here flat. They may however have a slight convexity and / or concavity.

[0057] The movement of the first locking member 14 between its locking and release positions is controlled by a first cremone bolt 16 arranged in the first upright 5. The first cremone bolt 16 is movable in the first longitudinal direction II-II according to a bidirectional translation movement illustrated by the double arrow 17. The movement of the first cremone bolt 16 is controlled by the rotation of a first handle 25 carried by the first opening 2.

[0058] The movement of the second locking member 15 between its locking and release positions is controlled by a second cremone bolt 18 arranged in the second upright 6. The second cremone bolt 18 is movable in the second longitudinal direction III-III according to a bidirectional translation movement illustrated by the double arrow 19. The movement of the second cremone bolt 18 is controlled by the rotation of a second handle 26 carried by the second opening 3.

[0059] The first locking member 14 is integral with the first cremone bolt 16. Similarly, the second locking member 15 is integral with the second cremone bolt 18.

[0060] The second locking member 15 is secured to the second cremone bolt 18 by means of a transverse screw 20 ( figure 9 in particular) so that any movement of the second cremone 18 in the second longitudinal direction III-III causes a movement of the second locking member 15 by the same distance in the second longitudinal direction III-III.

[0061] The first locking member 14 is fixed to the first cremone bolt 16 by means of two lugs 16a and 16b respectively engaged with free sliding in the first longitudinal direction II-II in oblong holes 14a and 14b, having a predetermined length, of the first locking member 14. The lugs 16a and 16b are for their part integral with the first cremone bolt 16 so that any movement of the first cremone bolt 16 in the first longitudinal direction II-II causes an equal movement of the lugs 16a and 16b in the first longitudinal direction II-II.The first locking member 14 is thus arranged to slide on the first cremone bolt 16 in the first longitudinal direction II-II according to a predetermined free travel (depending on the length of the oblong holes 14a and 14b, as well as the height of the lugs 16a and 16b in the first longitudinal direction II-II) and can, beyond said predetermined free travel, be driven by the first cremone bolt 16 in the first longitudinal direction II-II.

[0062] It follows that: the first locking member 14 is moved between its locking and release positions according to a first stroke C1 (see for comparison the figures 8 And 9 on the one hand, and the figures 11 And 12 on the other hand), the second locking member 15 is moved between its locking and release positions according to a second stroke C2 (see for comparison the figures 8 And 14), the first C1 and second C2 races have different lengths (the length of the first race C1 is here less than the length of the second race C2, as can be seen by comparing the figures 11 And 14 ).

[0063] The operation of French window 1 will now be explained in connection with the figures 5 And 7 has 16 .

[0064] In the initial state illustrated on the figures 5 And 7 has 9 , the first 2 and second 3 openings are in the closed position ( figure 2 ). The first 5 and second 6 uprights are arranged in correspondence with each other in the transverse direction VV to form a central upright 7 of a French window 1. The first locking member 14 is in the locking position and the second locking member 15 is also in the locking position. The first 14 and second 15 locking members are then supported in the transverse direction VV by means of their respective first S1 and second S2 support surfaces which thus hold the first 5 and second 6 uprights (and therefore the openings 2 and 3) at a first distance D1 from each other in the transverse direction VV. This distance D1 is chosen in such a way that the first 12 and second 13 seals are compressed between the first 5 and second 6 uprights in the transverse direction VV.

[0065] More precisely, the first S1 and second S2 support surfaces bear against each other along their generally planar vertices S10 and S20.

[0066] When a user begins by manipulating the first opening 2, he rotates the first handle 25 through an angular travel of 180 degrees ( figure 11 ). The first cremone bolt 16 slides in the first longitudinal direction II-II and then moves the lugs 16a and 16b accordingly (in practice towards the top of the French window 1).

[0067] Initially, the lugs 16a and 16b slide in the oblong holes 14a and 14b, so that the first locking member 14 remains stationary in the first longitudinal direction II-II. This is the predetermined free (relative) travel between the first locking member 14 and the first cremone bolt 16.

[0068] In a second step, once the lugs 16a and 16b have reached the upper end 140a and 140b of the oblong holes 14a and 14b, the continued movement of the lugs (driven by the first cremone bolt 16) causes the first locking member 14 to slide in the first longitudinal direction II-II (in practice towards the top of the French window 1) until the first locking member 14 is brought into the release position after a first stroke C1. The first bearing surface S1 is then moved away in the first longitudinal direction II-II away from the second bearing surface S2. We are then in the configuration illustrated in the figures 10 à 12 .

[0069] The first upright 5 can then be moved relatively apart in the transverse direction VV away from the second upright 6 (in particular by the first 12 and second 13 seals which elastically return to their pre-compression shape and / or by a separation force induced by the user on the first opening 2 when manipulating the first handle 25), to be arranged at a second distance D2 (greater than the first distance D1) from the second upright 6. The distance D2 is chosen in such a way that the first 12 and second 13 seals are not (or are only slightly) compressed between the first 5 and second 6 uprights in the transverse direction VV.

[0070] The first opening 2 can then be slid relative to the second opening 3 in the sliding direction II according to a translational movement illustrated by the arrow 21.

[0071] When the first opening 2 slides, the first bearing surface S1 is no longer in correspondence with the second bearing surface S2 in the first longitudinal direction II-II.

[0072] When the user wishes to close the French window 1, he brings the first opening 2 back in a translational movement opposite to that illustrated by the arrow 21, so as to place the first 2 and second 3 openings in the closed position ( figure 2 ). The first S1 and second S2 bearing surfaces are thus brought into correspondence with each other along the first longitudinal direction II-II. We then find ourselves in the configuration illustrated in the figures 10 à 12 .

[0073] The user then applies a reverse maneuver to the first rotating handle 25 carried by the first opening 2: the first cremone bolt 16 moves the first locking member 14 towards its proximal position.

[0074] During this movement, the first locking member 14, supported by the lugs 16a and 16b, first comes into contact along its oblique face S12 with the oblique face S21 of the second locking member 15.

[0075] The lugs 16a and 16b then move under the effect of the first cremone bolt 16 in the oblong holes 14a and 14b, until they come to the lower ends 141a and 141b of the oblong holes 14a and 14b. During this time, the first locking member 14 remains stationary relative to the second locking member 15.

[0076] Finally, the lugs 16a and 16b complete their movement under the effect of the first cremone bolt 16, and in doing so again drive the first locking member 14 which then continues its movement relative to the second locking member 15, until reaching its locking position ( figures 5 And 7 has 9) in which the first locking member 14 comes into contact along its plane apex S10 with the plane apex S20 of the second locking member 15. This produces a relative bringing together of the first 5 and second 6 uprights along the transverse direction VV, again ensuring compression of the joints 12 and 13 between the two uprights 5 and 6.

[0077] It is understood that the first S1 and second S2 bearing surfaces cooperate by wedge effect (thanks to the relative orientation of the oblique sides S12 and S21) to bring the first 5 and second 6 uprights together in the transverse direction VV when the second locking member 15 is in the locking position and the first locking member 14 is moved towards its locking position.

[0078] Starting from the initial state illustrated on the figures 5 And 7 has 9, the user can start by manipulating the second opening 3. To do this, he rotates the second handle 26 through an angular travel of 180 degrees ( figure 14 ). The second cremone bolt 18 slides along the second longitudinal direction III-III and then moves the second locking member 15 accordingly (in practice towards the top of the French window 1).

[0079] There is no free (relative) travel between the second locking member 15 and the second cremone bolt 18: the sliding of the second cremone bolt 18 in the second longitudinal direction III-III immediately drives the second locking member 15 until it is brought into the release position after a second travel C2 (the length of which is thus greater than that of the first travel C1). The second bearing surface S2 is then moved away in the second longitudinal direction II-II away from the first bearing surface S1. We are then in the configuration illustrated in the figures 13 et 14 .

[0080] The second upright 6 can then be moved relatively apart in the transverse direction VV away from the first upright 5 (in particular by the first 12 and second 13 seals which elastically return to their pre-compression shape and / or by a separation force induced by the user on the second opening 3 when manipulating the second handle 26), to be arranged at a second distance D2 (greater than the first distance D1) from the second upright 6. The distance D2 is chosen in such a way that the first 12 and second 13 seals are not (or are only slightly) compressed between the first 5 and second 6 uprights in the transverse direction VV.

[0081] The second opening 3 can then be slid relative to the first opening 2 in the sliding direction II according to a translational movement illustrated by the arrow 22.

[0082] When the second opening 3 slides, the second bearing surface S2 is no longer in correspondence with the first bearing surface S1 in the second longitudinal direction III-III.

[0083] When the user wishes to close the French window 1, he brings the second opening leaf 3 back in a translational movement opposite to that illustrated by the arrow 22, so as to place the first 2 and second 3 opening leaves in the closed position ( figure 2 ). The first S1 and second S2 bearing surfaces are thus brought into correspondence with each other along the second longitudinal direction III-III. We then find ourselves in the configuration illustrated in the figures 13 et 14 .

[0084] The user then applies a reverse maneuver on the second rotary handle 26 carried by the second opening 3: the second cremone bolt 18 moves the second locking member 15 towards its proximal position. During this movement, the second locking member 15 first comes into contact along its oblique face S22 with the oblique face S11 of the first locking member 14. The second locking member 15 then continues its movement relative to the first locking member 14, until reaching its locking position ( figures 5 And 7 has 9 ) in which the second locking member 15 comes into contact along its plane apex S20 with the plane apex S10 of the first locking member 14. This produces a relative bringing together of the first 5 and second 6 uprights along the transverse direction VV, again ensuring compression of the joints 12 and 13 between the two uprights 5 and 6.

[0085] It is understood that the second S2 and first S1 bearing surfaces cooperate by wedge effect (thanks to the relative orientation of the oblique sides S22 and S11 to bring the first 5 and second 6 uprights closer together in the transverse direction VV when the first locking member 14 is in the locking position and the second locking member 15 is moved towards its locking position.

[0086] We can thus see that the user can manipulate either of the openings 2 and 3 without any problem, and without any imposed order.

[0087] There is also no disadvantage in the user operating the first and second handles 25 and 26 of the first 2 and second 3 openings. In such a case: the first locking member 14 is brought into the release position after a first stroke C1, and the second locking member 15 is brought into the release position after a second stroke C2.

[0088] Although the first 16 and second 18 cremones have made strokes of the same lengths in the first II-II and second III-III longitudinal directions, the first C1 and second C2 strokes have different lengths, so that the first S1 and second S2 bearing surfaces are located apart from each other in the first II-II and second III-III longitudinal directions when the first 14 and second 15 locking members are in the released position.

[0089] We are then in the configuration illustrated on the figures 15 et 16 , in which the first 5 and second 6 uprights are arranged at a second distance D2 from each other, allowing the first 12 and second 13 seals not to be (or to be only slightly) compressed between the first 5 and second 6 uprights. The user can choose to slide the second opening 3 relative to the first opening 2 in the sliding direction II according to a translational movement illustrated by the arrow 22, or slide the first opening 2 relative to the second opening 3 in the sliding direction II according to a translational movement illustrated by the arrow 21. During one and / or the other of these sliding operations, no conflict occurs between the first locking member 14 and the second locking member 15.

[0090] When the user wishes to close the French window 1, he brings the first 2 and / or second 3 opening back to the closed position ( figure 2 ). We are then in the configuration illustrated on the figures 15 et 16 where the first S1 and second S2 bearing surfaces are located in correspondence (but apart) from each other according to the first II-II and second III-III longitudinal directions.

[0091] If the user starts to operate the first handle 25, we find ourselves in the configuration illustrated in the figures 13 et 14 , and the user then has to operate the second handle 26 to achieve the initial configuration of the figures 5 And 7 has 9 by compressing the first 12 and second 13 joints.

[0092] If the user starts to operate the second handle 26, we find ourselves in the configuration illustrated in the figures 10 à 12 , and the user then has to operate the first handle 25 to achieve the initial configuration of the figures 5 And 7 has 9by compressing the first 12 and second 13 joints.

[0093] On the figure 17 a variant of the first 14 and second 15 locking members is illustrated.

[0094] In this variant, the first bearing surface S1 has, in the sliding direction II, a first section S1T1 of the first bearing surface S1 and a second section S1T2 of the first bearing surface S1 connected by a step 23 with a first bearing facet 23a arranged so that, when the first 14 and second 15 locking members are in the locking position, the first bearing facet 23a opposes a relative movement of the first 14 and second 15 locking members away from each other in the sliding direction II.

[0095] This provides increased security for the French window 1 against intrusions by malicious persons into a building. Indeed, when the first 14 and second 15 locking members are in the locking position, sliding of the first 2 and second 3 openings is prevented as long as at least one of the first 14 and second 15 locking members is not moved to the release position (which is done from the inside of the building, here by means of the handles 25 and 26 carried by the first 2 and second 3 openings).

[0096] Symmetrically, the second bearing surface S2 has, in the sliding direction II, a first section S2T1 of the second bearing surface S2 and a second section S2T2 of the second bearing surface S2 connected by a step 24 with a second bearing facet 24a arranged so that, when the first 14 and second 15 locking members are in the locking position, the second bearing facet 24a opposes a relative movement of the first 14 and second 15 locking members away from each other in the sliding direction II.

[0097] The present invention is not limited to the embodiments which have been explicitly described, but it includes the various variations and generalizations contained within the scope of the following claims.
