Description

[0001] The invention relates to a wing arrangement according to the preamble of claim 1.

[0002] A sash assembly with features of the preamble of claim 1 is known from EP 3 363 976 A1. There, a rotation-limiting assembly is provided on a window with a frame and a sash. A rotatable locking element is provided on a rotation-limiting device in an opening, into which a rotation-limiting element can engage. To fix the rotation-limiting element relative to the locking element, the locking element can be rotated relative to the rotation-limiting device. The sash is then locked in a partially open position relative to the frame.

[0003] EP 4 006 277 A1 (post-published) discloses a sash assembly with a frame, pivotable sash, a handle, a guide body, a pivot arm and an opening limiting device with a self-locking device.

[0004] The invention is based on the object of providing a reliable rotary opening limiter on a sash assembly using simple design means, while reducing the risk of incorrect operation. Operation as simply as possible is desirable.

[0005] The invention solves this problem by a wing arrangement having the features of claim 1. The wing arrangement has a frame (fixed frame) and a wing of a door or window pivotably mounted on the frame.

[0006] An opening limiting device is provided that allows pivoting of the sash relative to the frame, in particular starting from a closed position of the sash, only up to a defined, partially open position (the pivoting movement of the sash is limited from the closed position in the opening direction). The opening limiting device comprises a switching rod, a guide device, and a pivot arm.

[0007] The shift rod is guided along the leaf for displacement along a longitudinal direction. For example, the leaf may have a groove for guiding the shift rod. The groove may have lateral groove edges that extend into the clear cross-section of the leaf-side groove and engage behind guide sections projecting laterally from the shift rod when the shift rod is positioned in the groove.

[0008] The switching rod is coupled by means of a drive rod to a handle arranged on the leaf side in such a way that the switching rod can be displaced along the longitudinal direction by actuating the handle. In particular, the switching rod can be moved into different switching positions depending on the actuating positions of the handle. Thus, defined actuating positions of the handle (e.g. closed position (e.g. 0° position), first opening position (e.g. 90° position) and second opening position (e.g. 180° position)) can in turn correspond to defined switching positions of the switching rod (e.g. a first, second and third switching position). The handle can be coupled to a gear that converts the rotary movement of the handle into a translational movement, e.g. for the drive rods.

[0009] The guide device is fixed to the wing (non-displaceably). The switching rod and the guide device are arranged such that they at least partially overlap each other along the longitudinal direction. The guide device has a guide groove that is closed at one end. In particular, the guide groove can extend along the longitudinal direction. Advantageously, the guide device can be formed in one or more parts, in particular, it can comprise or consist of one or more guide parts. For example, it is conceivable for a groove that is closed on one side to be formed in the at least one guide part.

[0010] The pivot arm is pivotably mounted on the frame at one end. For example, the pivot arm can have a bearing block at one end, by means of which the pivot arm can be attached to the frame (fixed frame), e.g., by clamping or screwing the bearing block to the frame. The pivot arm can then be pivoted relative to the bearing block. One or more stops can be provided on the bearing block to limit the pivoting movement of the pivot arm in the closing direction (closed position). A detent, e.g., spring-loaded, can be provided to hold the pivot arm in the closed position.

[0011] The pivot arm has a pin at its other end that engages the guide groove of the guide mechanism, at least when the sash is partially open. In the partially open position, the pin rests against the closed end of the guide groove, limiting pivoting of the sash in the opening direction beyond the partially open position. This prevents further pivoting of the sash in the opening direction away from the frame.

[0012] The sash arrangement further comprises a self-locking device which is configured to automatically lock the pin such that the pin is captured in the guide groove (i.e., displacement of the pin out of the guide groove is blocked) at least when it rests against the closed end of the guide groove (i.e., when the sash is in the partially open position). In other words, the self-locking device is configured to automatically lock the sash relative to the frame in the partially open position. In particular, the self-locking device can be configured to automatically lock the pin when, and in particular only when, the pin rests against the closed end of the guide groove.

[0013] Such a design makes it possible to achieve a reliable opening limit with simple structural means. Furthermore, the fact that the sash is automatically locked in the partially open position minimizes the risk of incorrect operation. In particular, it can prevent the sash from being swung from the partially open position to the closed position, for example, in the event of a gust of wind. In other words, it can ensure that a sash that is only partially opened, for example, for ventilation, is secured in this position.

[0014] In order to move the sash from the partially open position back to the closed position, it is necessary to release the self-locking device. For this purpose, it can be advantageous if the self-locking device is designed such that the locking of the pin can be released again by actuating the handle, so that the pin can be moved away from the closed end of the guide groove, in particular out of the guide groove. In this respect, the self-locking device can be configured such that, by actuating the handle, it can be moved from the locking configuration locking the pin into a release configuration that no longer locks or releases the pin, in which the pin can be moved out of the guide groove.

[0015] For example, it is conceivable for the self-locking device to interact with the handle in such a way that the locking of the pin can be released again by moving the handle from one actuating position, e.g., 90° position, to another actuating position (e.g., 0° position). Such a design enables particularly simple and intuitive operation of the sash assembly. In particular, it is not necessary to provide additional switching elements, such as additional levers or buttons, to release the self-locking device. This also contributes to a simple and cost-effective design of the sash assembly.

[0016] Furthermore, according to the invention, the self-locking device comprises a locking member. The locking member is designed such that it can assume a locking position and a release position. In the locking position, the locking member is arranged such that the pin of the pivot arm is blocked in the guide groove, i.e., the pin cannot be displaced out of the guide groove, in particular, cannot be displaced along the guide groove. In the release position, the locking member is arranged such that the pin is released, i.e., can be displaced out of the guide groove.

[0017] Self-actuation of the self-locking device is achieved by pre-tensioning the locking member into the locking position, in particular by spring pre-tensioning it. In this respect, the locking member can be biased toward the position blocking the pin. For example, it is conceivable that the locking member is transferred from the release position to the locking position by the pre-tension when the pin has passed the locking member or is resting against the closed end of the guide groove (i.e., when the leaf is in the partially open position).

[0018] For particularly simple operation, it may also be advantageous if the locking member interacts directly or indirectly with the shift rod in such a way that the locking member can be moved from the locked position to the release position by moving the shift rod along its longitudinal direction. In this respect, the locking member can be mechanically moved into the release position by operating the handle. Such a design enables reliable and intuitive operation of the self-locking device and is also cost-effective.

[0019] Specifically, the shift rod can have a first shift section and a second shift section. The first shift section can be designed such that the locking member is in the release position when it interacts with the first shift section, in particular when it is in contact. The second shift section can be designed such that the locking member is in the locking position when it interacts with the second shift section, in particular when it is in contact. In particular, the shift rod can be designed and coupled to the handle in such a way that, depending on a shift position of the handle, either the first shift section or the second shift section interacts with the locking part, in particular when it is in contact.

[0020] When the handle is in a first actuating position (e.g., 0° position or closed position), the shift rod can expediently be in a first switching position in which the locking member interacts with the first switching section of the shift rod (release position of the locking member). In this respect, by moving the handle into the first actuating position, in particular from a second actuating position explained below, the locking of the pin by the locking member can be released, so that, for example, the pin can be moved out of the guide groove.

[0021] Advantageously, when the handle is in a second actuating position (e.g., 90° position), the shift rod can be in a second switching position, in which the locking member interacts with the second switching section of the shift rod, in particular, is in contact (locking position of the locking member). Thus, by actuating the handle, in particular by moving the handle between the first and second actuating positions, the locking member can be transferred between the release position and the locking position.

[0022] A pin guide can expediently be provided on the switching rod, which has lateral wall sections projecting beyond the switching rod. The wall sections are in particular spaced apart from one another in such a way as to accommodate the pin, in particular a head section of the pin, between them. The pin guide guides the pin laterally to the longitudinal direction of the switching rod at least in one switching position or in two switching positions of the switching rod, in particular in the first and second switching positions explained above, when the pin is located outside the guide groove of the guide device. For example, when the wing is in the closed position, the pin guide can serve to guide the pin and to insert it into the guide groove of the guide device or the guide part when the wing is opened from the closed position and the pin moves towards the closed end of the guide groove.

[0023] Specifically, the pin guide can be formed integrally with the shift rod (e.g., using a single material design). This reduces the number of components to be designed, manufactured, and assembled. It also promotes a stable design.

[0024] Alternatively, the pin guide can be designed separately from the shift rod and can be mounted on the shift rod, in particular can be placed onto the shift rod. A separate design simplifies the construction of the shift rod. It also enables the use of different materials for the shift rod and pin guide. The shift rod and pin guide can be designed such that they can be placed inside each other for assembly; for example, the shift rod can be placed inside the pin guide. To couple the shift rod and pin guide, retaining lugs and corresponding recesses for receiving the retaining lugs can be provided, for example retaining lugs on the shift rod and recesses on the pin guide. The pin guide can have two lateral wall sections and a base section that connects the wall sections to one another.On the pin guide, particularly on the wall sections, guide lugs projecting outward at the sides can be arranged for engagement with a groove formed on the sash. The sash-side groove can be constructed as described above. Specifically, the guide groove can extend along a central longitudinal direction of the guide device and be delimited laterally by walls, with the pin guide being designed such that the pin guide can be inserted between the walls into the guide groove. This promotes a compact and flexible design of the opening limiting device.

[0025] The handle can expediently have a third actuating position, in particular a 180° position. When the handle is in this third actuating position, the switching rod can preferably be in a third switching position in which the pivot arm pin is located outside the guide device and outside the pin guide. The sash can then be pivoted relative to the frame between the closed position and an open position in which the sash is wider open than in the partially open position. In this respect, the sash arrangement can be configured such that the opening-limiting device no longer restricts sash opening in the third actuating position of the handle.With such a leaf arrangement, it is possible to decide, simply by operating the handle, whether the opening limiting device is effective (i.e., a pivoting movement of the leaf from the closed position is limited to a partially open position) or whether the leaf can be opened beyond this partially open position, for example, into a maximum open position. In the third actuating position, the switching rod can, in particular, interact with the locking member, in particular, be in contact, such that the locking member is in the release position.

[0026] Within the scope of an advantageous embodiment, the locking member can be designed as a tilting bolt. The tilting bolt can be held, in particular mounted, on the guide device so as to be pivotable about a pivot axis. Depending on its pivot position, the tilting bolt can assume a locking position, in particular the one described above, or a release position, in particular the one described above. Such a tilting bolt mechanism is easy to manufacture and also promotes reliable function of the self-locking device. The pivot axis can preferably be oriented parallel to a width direction of the shift rod. In particular, the pivot axis can be a horizontal axis.

[0027] The tilt bolt can be preloaded into the locking position by means of a spring device. Advantageously, the spring device can comprise or consist of a torsion spring. The torsion spring, in turn, can be mounted on the guide device.

[0028] The rocker latch can, in particular, have a locking portion that interacts with the pin in the locked position, and an actuating portion that interacts with the shift rod. In particular, the rocker latch can be preloaded such that the actuating portion of the rocker latch is pressed against the shift rod, preferably in contact with the shift rod. The locking portion and the actuating portion can advantageously be arranged at two opposite ends of the rocker latch, such that the pivot axis is arranged between the two portions. The rocker latch can thus form a type of rocker, which can assume a locking position or a release position depending on the pivot position. In particular, the actuating portion interacts directly with the shift rod, which promotes reliable actuation with comparatively low complexity.

[0029] Specifically, the rocker latch can be arranged and interact with the shift rod such that, in the release position (i.e., when the actuating portion is in contact with the first shifting portion of the shift rod), the rocker latch is oriented substantially parallel to the shift rod, so that the pin can be displaced with its head portion over the rocker latch. In the locking position (i.e., when the actuating portion is in contact with the second shifting portion of the shift rod), the rocker latch can be arranged obliquely or at an angle to the shift rod such that the actuating portion points toward the shift rod and the locking portion points away from the shift rod.

[0030] The second switching section of the switching rod can expediently be designed as an insertion section for the actuating section of the rocker latch, so that when the rocker latch overlaps with the second switching section (i.e. the switching rod is in the second switching position or the handle is in the second actuating position), its actuating section can at least partially penetrate into the insertion section. In particular, the rocker latch penetrates automatically or independently into the insertion section due to the spring preload, so that the rocker latch is automatically transferred into the locking position when the actuating section overlaps with the insertion section. It is conceivable for the switching rod to have a reduced material thickness in the insertion section compared to the first switching section, e.g. to have a local recess on the surface on a side facing the rocker latch.It is also conceivable that the second switching section is designed as a local recess in the switching rod, e.g. in the form of a hole or a bore.

[0031] Advantageously, the tilt bolt can be arranged in a movement path of the pivot arm's pin from the open end of the guide groove to the closed end of the guide groove, in particular such that the pin passes the tilt bolt during its displacement from the open end to the closed end (i.e. during a pivoting movement of the sash from the closed position to the partially open position). In particular, the tilt bolt can be arranged in such a way that along the movement path of the pin from the free end of the guide groove to the closed end, the actuating section and then the locking section are passed. In the locking position (i.e. in particular when the handle is in the second actuating position orSwitching rod in the second switching position), the tilt bolt can then preferably be arranged in such a way that the pin, as it moves from the open end to the closed end of the guide groove, slides along a sliding surface of the tilt bolt and in the process pivots the tilt bolt about the pivot axis in the direction of the release position. After the pin has passed the sliding surface, the tilt bolt can then be automatically moved back into the locking position by the pre-tension. In other words, as the sash opens, the tilt bolt can first be pivoted from the closed position into the release position by the pin and then, after the pin has passed the tilt bolt, snaps back into the locking position.

[0032] To enable flexible use of the sash assembly, it can be advantageous if the sash can be hinged to the right or left as required, i.e., the sash is pivotally mounted on the left or right of the frame. It can then be advantageous if the guide device, or at least one guide part, is designed such that it can be mounted on the sash in two different positions, 180° opposite each other. This allows the same guide device to be used for both right- and left-hinged sash assemblies. This reduces the number of different components required and thus facilitates warehousing and spare parts supply.

[0033] Advantageously, the pin guide can also be designed such that it can be mounted on the shift rod in two different positions or orientations, 180° apart from each other. In other words, the pin guide can be easily mounted on the shift rod in two opposite positions for use on right- or left-hinged sash arrangements.

[0034] Within the scope of a preferred embodiment, the opening limiting device and the self-locking device can be arranged, relative to the direction of gravity, between an upper cross member of the frame (frame cross member) and an upper cross member of the sash (sash cross member), between a lower cross member of the sash and a lower cross member of the frame, or between a vertical sash member on which the handle is located and a vertical frame member (adjacent to or associated with this sash member). This largely protects the opening limiting device and the self-locking device from environmental influences such as rain, dust, dirt, or the like.

[0035] Independently of this, two opening limiting devices can optionally be provided, arranged at different locations between the sash and the frame. For example, a first opening limiting device can be arranged between an upper cross member of the frame and an upper cross member of the sash, and a second opening limiting device can be arranged between a lower cross member of the sash and a lower cross member of the frame. This allows for higher loads, such as higher wind loads, to be absorbed.

[0036] Independently of this, the sash can optionally be additionally locked in the closed position via one or more locking points on the frame. For this purpose, one or more locking devices can be provided. The handle can then be coupled to the at least one locking device, in particular via the drive rod, in such a way that the at least one locking device can be actuated by the handle. This contributes to particularly simple operation of the sash arrangement, since the at least one locking device and the self-locking device can be actuated by the same handle.

[0037] The invention is explained in more detail below with reference to the figures, in which identical or functionally equivalent elements are provided with identical reference numerals. They show: Fig. 1 shows an embodiment of a wing arrangement in a schematic view; Fig. 2 shows the pivot arm of the opening limiting device from Figur 1 in a perspective view in isolation; Fig. 3 an assembly of the opening limiting device and the self-locking device of the wing arrangement from Figur 1 in a perspective exploded view; Fig.4a,b the assembly of Fig. 3 in a perspective view from above (view a) and from below (view b), each in the assembled state; and Fig. 5a-9b various schematic representations to explain the mode of operation of the opening limiting device and the self-locking device, wherein an exemplary opening position of the wing is shown on the right and a corresponding functional position of the opening limiting device or self-locking device is shown on the left in a plan view (top left view) and in a side view (bottom left view).

[0038] Figur 1 shows a sash assembly, designated overall by reference numeral 10. The sash assembly 10 comprises a frame or fixed frame 12 and a sash 14 of a door or window. The sash 14 is pivotally mounted on the frame 12, for example, by means of hinges 16, and can be pivoted about a pivot axis 18 (pivoting fitting).

[0039] The frame 12 has a lower frame cross member 20, an upper frame cross member 22, and two vertical frame members 24, 26. The sash frame or casement 14 has a lower casement cross member 28, an upper casement cross member 30, and two vertical casement members 32, 34. These define a casement element 36, for example, a glazed casement panel 36.

[0040] A handle 38 is provided on the sash 14, by means of which locking devices (not shown) can be actuated to lock the sash 14 to the frame 12. In addition, the sash assembly 10 has an opening limiting device 40, which will be explained in more detail below, with a self-locking device 42, which is arranged, for example, between the upper frame cross member 22 and the upper sash cross member 30 (in Fig. 1 (only indicated). The opening limiting device 40 and the self-locking device 42 can also be arranged at other locations between the frame 12 and the sash 14. The use of two opening limiting devices 40 with a self-locking device 42 arranged at different locations between the frame 12 and the sash 14 is also conceivable.

[0041] As explained in detail below, the opening limiting device 40 only allows the sash 14 to pivot relative to the frame 12 up to a defined, partially open position (cf. Fig. 5a bis 6b ). The opening limiting device 40 comprises a pivot arm 44 arranged on the frame side (cf. Fig. 2 ), a switching rod 46 arranged on the wing side (cf. Fig. 3 ) and a guide device 48 arranged on the wing side (cf. Fig. 3 ). A limitation of the opening angle of the wing 14 is achieved in that the pivot arm 44 engages with a pin 50 in a guide groove 52 of the guide device 48, which is closed at one end (explained in more detail below).

[0042] The Figur 2 shows the pivot arm 44 in isolation. The pivot arm 44 is pivotally mounted at one end 54 on the upper frame cross member 22 of the frame 12 (not shown) and has the aforementioned pin 50 at the other end 56. The pin 50 has a shaft section 58 and a head section 60 whose cross section is (radially) wider than the shaft section 58. At the end 54, the pivot arm 44 has a bearing block 62, by means of which the pivot arm 44 can be fastened to the frame 12, e.g., by clamping or screwing. A stop 64 is provided on the bearing block 62, which limits a pivoting movement of the pivot arm 44 relative to the bearing block 62 in the closing direction. In the example, a detent 68 is provided, which is acted upon by a spring 66 and holds the pivot arm 44 in the closed position relative to the bearing block 62. If the swivel arm 44 is to be swiveled, the detent 68 must first be overcome.

[0043] The guide device 48 and the switching rod 46 of the opening limiting device 40 are in Fig. 3 shown in detail. The guide device 48 comprises a guide part 70 in which the above-mentioned guide groove 52 is formed. As can be seen from Fig. 3 As can be seen, the guide groove 52 extends along a longitudinal direction 72 and has an open end 74 and a closed end 76. The guide groove 52 is laterally delimited by walls 78, 80.

[0044] The guide part 70 is fixedly fixed to the upper wing cross member 30 of the wing 14. For example, lateral guide sections 82, 84 are formed on the walls 78, 80 for coupling to a groove arranged on the wing side of the upper wing cross member 30 (see Fig. 4a ). The guide sections 82, 84 are designed to engage behind the lateral groove edges of the sash-side groove. At least two threaded holes 86 are formed on the guide part 70 to fasten the guide part 70 to the sash-side groove. In the example, the threaded holes 86 can accommodate screws 88, e.g., grub screws, to clamp the guide part 70 relative to the sash-side groove.

[0045] The switching rod 46 is guided on the wing 14 along the longitudinal direction 72, for example and preferably in a groove (not shown) formed on the upper wing cross member 30 of the wing 14. As can be seen from Fig. 4a und 4b As can be seen, the switching rod 46 and the guide device 48 or the guide part 70 overlap each other at least partially along the longitudinal direction 72.

[0046] A pin guide 90 is provided on the shift rod 46, which has lateral wall sections 92, 94 projecting beyond the shift rod 46. The wall sections 92, 94 are spaced apart from one another in such a way as to accommodate the pin 50, in particular the head section 60 of the pin 50, of the pivot arm 44, between them. In the example, the pin guide 90 is formed separately from the shift rod 46 and is connected to the shift rod 46 via an intermediate piece 96 and corresponding coupling elements 98. In embodiments not shown, the pin guide 90 can also be formed integrally with the shift rod 46. The pin guide 90 is designed such that the wall sections 92, 94 can be inserted between the walls 78, 80 into the guide part 70.

[0047] As already mentioned above, in the partially open position of the wing 14, the pin 50 engages in the guide groove 52 and rests against the closed end 76 of the guide groove 52 (cf. Fig. 6b ). This limits further pivoting of the sash 14 in the opening direction (away from the frame 12).

[0048] In order to automatically lock the wing 14 in this partially open position, the aforementioned self-locking device 42 is provided. The self-locking device 42 comprises a locking member 100, which in the example is designed as a tilting bolt 102. The tilting bolt 102 is pivotally mounted on the guide part 70 about a pivot axis 104 parallel to a width direction 103 of the switching rod 46. In the example, the tilting bolt 102 engages with a bolt portion 106 in a corresponding receptacle 108 in the guide part 70 (see. Fig. 3 ).

[0049] In the example, the toggle latch 102 comprises a base portion 110, one end 112 of which forms a locking portion 114 for the pin 50 (explained in more detail below). A projection 118 projects from the opposite end 116 of the base portion 110, forming an actuating portion 120 of the toggle latch 102. As can be seen from Fig. 3 As can be seen, the pivot axis 104 is arranged between the locking section 114 and the actuating section 120. The tilting latch 102 thus forms a kind of rocker.

[0050] The rocker latch 102 is preloaded by a torsion spring 124 such that the actuating portion 120 is urged against the shift rod 46. In the example, the torsion spring 124 is held in a corresponding receptacle 128 on the guide part 70 by means of a bolt 126.

[0051] As explained below, the rocker latch 102 can assume a release position or a locking position depending on the displacement position of the shift rod 46. As shown in Fig. 3 As shown, the shift rod 46 comprises a first shift rod section 130, a second shift rod section 132 and a recess 134 arranged between the first and second shift rod sections 130, 132 in the form of an elongated hole 134 extending along the longitudinal direction 72. The elongated hole 134 forms a penetration section 138 into which the rocker latch 102 can penetrate with its actuating section 120. In embodiments not shown, it is also conceivable for the shift rod 46, instead of the recess 134, to have only a locally reduced material thickness compared to the surrounding shift rod sections 130, 132, for example, to have a local recess on the surface of the shift rod 46.

[0052] In the example shown, the rocker latch 102 and the shift rod 46 are positioned relative to one another in such a way that the rocker latch 102 assumes a release position when the actuating section 120 of the rocker latch 102 is in contact with a surface of the first or second shift rod section 130, 132, in which the pin 50 can be displaced with its head section 60 over the rocker latch 102 (cf. Fig. 5a , explained in more detail below). The first shift rod section 130 thus forms a first switching section 140 of the shift rod 46. By way of example and preferably, the rocker latch 102 is arranged essentially parallel to the shift rod 46 in the release position (cf. Fig. 5a ).

[0053] If the switching rod 46 is positioned relative to the rocker bolt 102 such that the actuating section 120 overlaps with the penetration section 138 of the switching rod 46, the rocker bolt 102 penetrates into the penetration section 138 due to the spring preload by the torsion spring 124, so that the rocker bolt 102 is pivoted about the pivot axis 104 (in Fig. 3 counterclockwise). The rocker latch 102 is consequently arranged obliquely or at an angle to the shift rod 46 such that the locking portion 114 points away from the shift rod 46 (locking position, see Fig. 5b ). The penetration section 138 thus forms a second switching section 142 of the switching rod.

[0054] In order to simplify the sliding of the actuating section 120 along the shift rod surface or into or out of the penetration section 138, the actuating section 120 is, for example, rounded on its side facing the shift rod 46 (cf. Fig. 3 ).

[0055] As already mentioned, depending on the displacement position of the switching rod 46, either the first or the second switching section 140, 142 can interact with the actuating section 120 of the tilt bolt 102. In order to be able to displace the switching rod 46 along the longitudinal direction 72, the switching rod 46 is coupled to the handle 38 arranged on the leaf side by means of at least one drive rod (not shown) in such a way that the switching rod 46 can be brought into different switching positions depending on the actuating positions of the handle 38. In the example, a first drive rod (not shown) is connected to the pin guide 90 via a drive rod coupling element 144 and thus coupled to the switching rod 46. A second drive rod (not shown) is connected to the switching rod 46 via a drive rod connecting device 146.In the example, the drive rod connecting device 146 comprises an intermediate part 148 designed analogously to the above-mentioned intermediate part 96 and a connecting rod 150, which are attached to the switching rod 46 via corresponding coupling elements 152. The drive rod is then connected to the connecting rod 150 via a corresponding drive rod coupling element 144. It is also conceivable for the drive rods to be connected directly to the switching rod 46.

[0056] The handle 38 can be rotated to different operating positions (e.g., 0°, 90°, 180°). The handle 38 is coupled to a gear (not shown) that converts the rotational movement of the handle 38 into a translational movement for the drive rod and thus into a displacement movement of the switching rod 46 along the longitudinal direction 72.

[0057] The functioning of the wing arrangement 10 is explained below using the Figuren 5a bis 9b explained.

[0058] Figur 5a shows the sash assembly 10 in the closed position, i.e., the sash 14 is located within the frame 12. The handle 38 is in a first actuating position (0° position or closed position). The locking mechanisms (not shown) for locking the sash 14 to the frame 12 are locked. The sash 14 cannot therefore be pivoted relative to the frame 12.

[0059] As from Figur 5a , View bottom left, shows that the switching rod 46 is in a first switching position corresponding to the first actuating position of the handle 38, in which the rocker latch 102 interacts with the first switching section 140 (surface of the first switching rod section 130, see above), so that the rocker latch 102 is in the release position. In this configuration, the pin 50 is located outside the guide part 70 in the pin guide 90, with the lateral wall sections 92, 94 enclosing the head section 60 of the pin 50 laterally to the longitudinal direction 72.

[0060] At the Figur 5b In the configuration shown, the wing 14 is located within the frame 12, but the handle 38 is opposite to the one shown in Fig. 5a The illustrated configuration is rotated 90° counterclockwise (second actuation position, 90° position). The locking mechanisms (not shown) for locking the sash 14 to the frame 12 are unlocked. The sash 14 can thus be pivoted relative to the frame 12.

[0061] As from Figur 5b , view bottom left, the switching rod 46 is in a second switching position corresponding to the second actuating position of the handle 38, in which the switching rod 46 is in relation to the Figur 5a shown position is shifted along the longitudinal direction 72 (in Fig. 5 "to the left"). By displacing the shift rod 46, the pin guide 90 was displaced a short distance into the guide part 70. The pin 50 is located outside the guide part 70 and still in the pin guide 90, with the lateral wall sections 92, 94 enclosing the head section 60 of the pin 50 laterally relative to the longitudinal direction 72.

[0062] In this second switching position of the switching rod 46, the actuating portion 120 of the rocker latch 102 overlaps with the penetration portion 138 (second switching portion 140) of the switching rod 46, so that the rocker latch 102 penetrates the penetration portion 138 with the actuating portion 120 due to the spring preload. The rocker latch 102 is thus in the locking position described above.

[0063] If the wing 14 is now moved from the Figur 5b shown configuration, the pin 50 slides in the guide groove 52 in the direction of the closed end 76 (cf. Fig. 6a ). As can be seen from Fig. 6a , bottom left view, the pin 50 slides with its head section 60 on a sliding surface 154 (see also Figur 3 ) of the tilting bolt 102, whereby the tilting bolt 102 is pivoted in the direction of the release position (cf. Fig. 6a ). Once the pin 50 has completely passed the tilting bolt 102, the tilting bolt 102 snaps back into the locking position due to the spring preload (cf. Figur 6b ). In this locking position, the pin 50 is caught between the guide groove 52 and the locking section 114 of the tilt bolt 102, so that the pin 50 cannot move in the direction of the free end 74 of the guide groove 52 (in Fig. 6b "to the right") and thus cannot be displaced from the guide groove 52. The wing 14 is thus automatically locked in the partially open position by the self-locking device 42.

[0064] To start from the Figur 6b In order to be able to close the sash 14 again in the configuration shown, i.e., to pivot it from the partially open position into the closed position, the self-locking device 42 must first be released. In other words, the tilt bolt 102 must be moved from the locked position into the released position. In the proposed sash arrangement 10, this is achieved by moving the handle 38 from the second actuating position (90° position) back into the first actuating position (0° position) (cf. Fig. 7a ). As in Fig. 7a , view bottom left, the shift rod 46 is then moved back into the Fig. 5a The first switching position shown (in the figures "to the right") is moved, in which the rocker latch 102 interacts with the first switching section 140 (surface of the first switching rod section 130, see above) and is thus in the release position. In the release position, the pin 50 can then slide over the rocker latch 102 from its contact with the closed end 76 of the guide groove 52 to the free end 74 of the guide groove (see Fig. 7b ).

[0065] However, before the wing 14 can be completely closed again, the handle 38 must be moved back into the 90° position (second actuating position) - at least if tumblers are provided - in order to enable, for example, the locking bolts of the tumblers to engage in the corresponding locking receptacles (cf. Fig. 8a ). If the leaf 14 is in the closed position again, the handle 38 can then be moved into the first actuating position (0° position) in order to lock the locking devices (cf. Fig. 8b ).

[0066] In Figur 9a The sash 14 is located within the frame 12, but the handle 38 is pivoted into a third confirmation position (180° position or second opening position). The locking mechanisms (not shown) for locking the sash 14 to the frame 12 are unlocked. The sash 14 can thus be pivoted relative to the frame 12. In this actuated position (180° position), the opening limiting device 40 is inactive, so that the sash 14 can be moved from the closed position beyond the partially open position, for example, into a fully open position.

[0067] As from Figur 9a , view bottom left, the switching rod 46 is in a third switching position corresponding to the third actuating position of the handle 38, in which the switching rod 46 is in relation to the Fig. 5b shown 90° switching position is shifted even further to the left, so that the rocker bolt 102 with its actuating section 120 interacts with the surface of the second switching rod section 132 and is thus in the release position.

[0068] As from Figur 9a , bottom left view, the pin guide 90 is pushed so far into the guide part 70 in this switching position that the pin 50 is located outside the guide part 70 and outside the pin guide 90. If, starting from this configuration, the wing 14 is opened, the guide part 70 and the switching rod 46, which are arranged on the wing 14, are pivoted away from the pivot arm 44, which is arranged on the frame 12 (cf. Fig. 9b). The sash 14 can thus be pivoted relative to the frame 12 like a conventional pivoting sash.
