Description

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

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

[0003] The invention is based on the objective of providing a reliable rotation opening limiter for a wing assembly using simple design means, thereby reducing the risk of incorrect operation. Easiest possible operation is desirable.

[0004] The invention solves this problem by means of a wing arrangement with the features of claim 1. The wing arrangement comprises a frame (fixed frame) and a wing of a door or window pivotably mounted on the frame.

[0005] An opening limiting device is provided that allows the sash to pivot relative to the frame, particularly from a closed position, only to a defined, partially open position (the pivoting motion of the sash is limited from the closed position in the opening direction). The opening limiting device comprises a switching rod, a guide, and a pivot arm.

[0006] The switching rod is guided so that it can slide along the sash in a longitudinal direction. For example, the sash can have a groove to guide the switching rod. The groove can have lateral groove edges that project into the clear cross-section of the groove on the sash side and engage guide sections projecting laterally from the switching rod when the switching rod is positioned in the groove.

[0007] The switching rod is coupled to a handle located on the wing side via a drive rod, such that actuating the handle allows the switching rod to be moved along its longitudinal direction. In particular, the switching rod can be moved into different switching positions depending on the actuation positions of the handle. Thus, defined actuation 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 gearbox that converts the rotary motion of the handle into a translational motion, e.g., for the drive rods.

[0008] The guide device is fixed to the wing (non-movably). The switching rod and the guide device are arranged such that they overlap each other at least partially 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 designed in one or more parts, in particular comprising or consisting of one or more guide parts. For example, it is conceivable that a groove closed at one end is formed in the at least one guide part.

[0009] The swivel arm is mounted to the frame at one end so that it can pivot. For example, the swivel arm may have a bearing block at one end, which allows it to be attached to the frame (fixed frame), for example by clamping or screwing the bearing block to the frame. The swivel arm can then pivot relative to the bearing block. One or more stops may be provided on the bearing block to limit the swivel arm's movement in the closing direction (closed position). A detent mechanism, for example spring-loaded, may be provided to hold the swivel arm in the closed position.

[0010] The pivot arm has a pin at its other end which engages in 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, thus limiting the sash's pivoting in the opening direction beyond the partially open position. Therefore, further pivoting of the sash away from the frame in the opening direction is blocked.

[0011] The sash assembly also includes a self-locking device designed to automatically lock the pivot such that the pivot is trapped in the guide groove (i.e., preventing any movement of the pivot out of the guide groove) 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 designed to automatically lock the sash relative to the frame in the partially open position.

[0012] In particular, the self-locking device may be configured to lock the pin automatically, and especially only when the pin rests against the closed end of the guide groove.

[0013] This design allows for reliable opening limitation using simple construction methods. Furthermore, the automatic locking of the sash in the partially open position minimizes the risk of accidental operation. In particular, it prevents the sash from being swung from the partially open to the closed position, for example, by a gust of wind. Thus, it ensures that a sash only partially opened, for example, for ventilation, remains securely in that position.

[0014] To return the sash from the partially open position to the closed position, it is necessary to release the self-locking mechanism. For this purpose, it can be advantageous if the self-locking mechanism is designed such that the locking of the pin can be released by actuating the handle, allowing the pin to be moved away from the closed end of the guide groove, and in particular, out of the guide groove altogether. In this respect, the self-locking mechanism can be configured so that, by actuating the handle, it can be moved from the locking configuration that secures the pin to a release configuration that no longer secures the pin, allowing the pin to be moved out of the guide groove. For example...Is it conceivable that the self-locking mechanism interacts with the handle in such a way that the locking of the pin can be released by moving the handle from one operating position, e.g., the 90° position, to another operating position (e.g., the 0° position)? Such a design allows for particularly simple and intuitive operation of the wing assembly. In particular, it is not necessary to provide additional switching elements, e.g., additional levers or buttons, to release the self-locking mechanism. This also contributes to a simple and cost-effective design of the wing assembly.

[0015] In an advantageous embodiment, the self-locking device can include a pivot bolt. The pivot bolt can be pivotally mounted on the guide device about a pivot axis, preferably vertical and oriented orthogonally to the switching rod and the longitudinal direction. In particular, depending on its pivot position, the pivot bolt can assume a closed position that engages the pin in the guide groove or an open position that releases the pin. Preferably, in the closed position, the pivot bolt engages the pin of the pivot arm at least partially. In the open position, the pivot bolt can preferably be arranged such that the pin is released, in particular, can be displaced from the guide groove. Such a pivot bolt promotes effective locking and is also comparatively simple and inexpensive to manufacture.

[0016] Specifically, the pivot bolt can have a receiving section for the partial, and in particular positive, reception of the pivot arm's pin. The receiving section can be designed such that it can partially engage the pin along its circumference. In particular, the pin rests against this receiving section when the pivot bolt is in the closed position. In this respect, the pin can be trapped by the pivot bolt in the closed position. In the open position, the pivot bolt can be arranged or oriented such that the receiving section releases the pin. Advantageously, the receiving section can be adapted to a pin contour, for example, by having a negative shape of an outer surface of the pin (e.g., segment-shaped).

[0017] Advantageously, the pivot bolt can be arranged in the path of movement of the pivot arm's pin from the open end of the guide groove to the closed end of the guide groove. In particular, the pivot bolt can be designed and / or arranged such that, during a movement of the pin from the free end of the guide groove to the closed end (i.e., when the sash pivots from the closed position to the partially open position), the pivot bolt can be moved from the open position to the closed position by the pin, or is moved by the pin. In this respect, the pin, during its movement from the open end to the closed end of the guide groove, can pivot the pivot bolt about the pivot axis. For example, the pin can interact with an actuating section of the receiving section and thus pivot the pivot bolt.The pivot bolt can preferably be designed and arranged such that, even when the pin moves in the opposite direction, i.e., from the closed end to the open end of the guide groove, it is pivoted by the pin, in particular from the closed position to the open position. A displacement of the pivot bolt between the open and closed positions can thus be achieved by moving the pin.

[0018] To lock the pivot bolt in the closed position and thus effectively engage the pin in the guide groove, it is generally conceivable that the pivot bolt, in the closed position, interacts with a contact section of the guide device by means of a force-fit and / or positive locking mechanism, thereby exerting a certain retaining force on the pin. In a preferred embodiment, the self-locking device can include a spring-loaded locking element. Preferably, the locking element is designed such that, when the pivot bolt is in the closed position, the spring preload automatically engages a locking position in which a pivoting movement of the pivot bolt from the closed position to the open position, and in particular a pivoting movement about the pivot axis, is blocked altogether. The self-locking device can be configured such that the pivot bolt is automatically locked by the spring-loaded locking element.It is automatically locked in the closed position. The pin is then securely locked in the guide groove (locking configuration of the self-locking device).

[0019] Specifically, the locking element can engage with a corresponding locking element receiving section of the swing bolt in a form-fitting manner. In particular, when the swing bolt is in the closed position and the locking element is in the locked position, the engagement section can engage positively with the locking element receiving section. This design promotes effective locking of the pivot, ensuring that the sash remains securely locked in the partially open position even under relatively high force.

[0020] To release the pin from the locking configuration (e.g., to return the sash from the partially open position to the closed position), it is necessary to move the locking element from the locked position to a release position in which the locking element is disengaged from the pivot bolt and / or allows pivoting movement of the pivot bolt. For this purpose, it can be advantageous if the locking element can be actuated by the switching rod.

[0021] In particular, the locking element can interact with the switching rod, either directly or indirectly, in such a way that by moving the switching rod along its longitudinal axis, i.e., by actuating the handle, the locking element can be moved from the locked position to the released position. Depending on the switching position or displacement of the switching rod, the locking element can therefore block or allow a pivoting movement of the pivot bolt around its pivot axis. This design enables reliable and intuitive operation of the self-locking device and is also cost-effective.

[0022] Specifically, the locking element can be guided on the guide device so that it is translationally displaceable between the locking position and the release position. In this respect, the locking element can assume a locking position and a release position, whereby in the locking position the locking element interacts with the pivot bolt in such a way that a pivoting movement of the pivot bolt about the pivot axis is blocked, and in the release position it is disengaged from the pivot bolt and / or allows a pivoting movement of the pivot bolt.

[0023] To automatically move the locking element into the locked position (and thus automatically lock the sash in the partially open position), the locking element can be pre-tensioned in the direction of the locked position. Preferably, the locking element can be spring-loaded in the direction of the locked position. In this case, the locking element can be biased in the direction that blocks the pivot bolt and thus locks the pin when it rests against the closed end of the guide groove. For example, it is conceivable that when the pivot bolt is in the closed position (pin at the closed end of the guide groove, sash partially open), the locking element is moved into the locked position by the pre-tension.

[0024] It is also conceivable that, when the swing bolt is in the open position, the locking element assumes a clamping position in which it forces the swing bolt into the open position. In this clamping position, the swing bolt can be held in the open position by the locking element, preventing it from being unintentionally moved into the closed position. In particular, the locking element can be positioned in the clamping position between the release position and the locked position.

[0025] Advantageously, the locking element can have an engagement section, in particular the engagement section described above, which can be engaged or disengaged from the pivot bolt in such a way that a pivoting movement of the pivot bolt about the pivot axis is selectively blocked or permitted, in particular allowed. For a particularly reliable locking of the pin in the guide groove and thus an effective locking of the sash in the partially open position, it can be advantageous if the engagement section is designed as a hook section, which can engage positively in a corresponding locking element receiving section of the pivot bolt.

[0026] Advantageously, the locking element can have a guide projection which interacts with a guide contour formed on the switching rod, so that the locking element can be selectively moved into either the locked or the released position by sliding the switching rod along its longitudinal direction (e.g., by actuating the handle). In this way, the self-locking device can be reliably actuated in a structurally simple manner. The guide contour can, for example, be formed in the switching rod by a material removal process, which facilitates particularly simple and cost-effective manufacturing.

[0027] Specifically, the guide contour can have a first guide section and a second guide section. The first guide section can preferably be designed such that when the guide projection is at the level of the first guide section, and in particular interacts with, or is preferably in contact with, the locking element is in the release position. The second guide section can preferably be designed such that when the guide projection is at the level of the second guide section, the locking element can be moved into the locked position (but may be prevented from doing so by the pivot bolt) or is already in the locked position (especially when the pivot bolt is in the closed position).

[0028] The switching rod can be suitably designed and coupled to the handle in such a way that, depending on the actuation position of the handle, either the first guide section or the second guide section interacts with the guide projection, in particular is in contact.

[0029] Advantageously, when the handle is in a first operating position (e.g., the 0° position or closed position), the switching rod can be in a first switching position in which the guide projection engages with the first guide section of the switching rod, so that the locking element is in the release position, specifically disengaged from the pivot bolt. Therefore, by moving the handle into the first operating position, particularly from a second operating position explained below, the locking of the pivot bolt and thus the locking of the pin by the pivot bolt can be released. The pin can then be moved from its position at the closed end of the guide groove towards the free end of the guide groove, thereby moving the pivot bolt from the closed position to the open position.

[0030] Advantageously, when the handle is in a second operating position (e.g., the 90° position), the switching rod can be in a second switching position in which the guide projection is located at the level of the second guide section of the switching rod. Preferably, the locking element is then engaged with the pivot bolt. For example, it is possible that the pivot bolt is in the closed position (e.g., when the pin rests against the closed end of the guide groove, i.e., the sash is in the partially open position). Then, when the handle is in the second operating position, the locking element can be in the locked position, in particular with its engagement section engaging the corresponding locking element receiving section (locking configuration). It is also possible that the pivot bolt is in the open position.Then, when the handle is in the second operating position, the locking element can assume the aforementioned clamping position, in which the locking element is pressed against the pivot bolt and prevents it from pivoting around the pivot axis (without itself being in the locking position).

[0031] Advantageously, a pin guide can be provided on the switching rod, having lateral wall sections projecting beyond the switching rod. These wall sections are spaced apart from one another to accommodate the pin, particularly a head section of the pin. The pin guide guides the pin laterally to the longitudinal direction of the switching rod, at least in one or two switching positions of the switching rod, especially in the first and second switching positions described above, when the pin is located outside the guide groove of the guide device. For example, when the sash is in the closed position, the pin guide can serve to guide the pin and insert it into the guide groove of the guide device as the sash is opened from the closed position and the pin moves towards the closed end of the guide groove.

[0032] Specifically, the pivot guide can be formed integrally with the shift rod (e.g., using a single material). This reduces the number of components to be designed, manufactured, and assembled. It also promotes a more robust design. Alternatively, the pivot guide can be designed separately from the shift rod and mounted to it, particularly by being placed on top of it. A separate design simplifies the construction of the shift rod. Furthermore, this allows for the use of different materials for the shift rod and the pivot guide.

[0033] Specifically, the guide device can extend along a central longitudinal direction and be laterally bounded by walls, with the pin guide being designed such that it can be inserted between the walls into the guide device. This facilitates a compact and flexible design of the opening limiting device.

[0034] Advantageously, the handle can have a third operating position, in particular the 180° position. Preferably, when the handle is in this third operating position, the switching rod can be in a third switching position in which the pivot pin of the pivot arm is located outside the guide device and outside the pivot guide, in particular between the guide device and the pivot guide. The sash can then be pivoted relative to the frame between the closed position and an open position in which the sash is opened further than in the partially open position. In this respect, the sash arrangement can be configured such that the opening limiter no longer restricts the sash opening in the third operating position of the handle.With such a wing arrangement, it is possible to decide, simply by operating the handle, whether the opening limiter is effective (i.e., whether the wing's pivoting movement from the closed position to a partially open position is limited), or whether the wing can be opened beyond this partially open position, e.g., to a fully open position. In the third operating position, the switching rod can interact with the guide projection, in particular be in contact, in such a way that the locking element is in the locked position or at least can be moved into the locked position.

[0035] To allow for flexible use of the sash arrangement, it can be advantageous if the sash can be hinged on the right or left as needed, meaning it can be pivotally mounted on the frame to open to either the left or right. In this case, it can be beneficial if the guide mechanism is designed so that it can be mounted on the sash in two different positions, 180° opposite each other. This allows the same guide mechanism to be used for both right- and left-hinged sash arrangements. This reduces the number of different components that need to be kept in stock, thus simplifying inventory management and spare parts supply.

[0036] Advantageously, the pivot guide can also be designed such that it can be mounted on the switching rod in two different positions or orientations that are 180° opposite to each other. In other words, the pivot guide can be easily mounted on the switching rod in two opposite positions for use on right- or left-hinged wing assemblies.

[0037] In a preferred embodiment, the opening limiter 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 limiter and the self-locking device from environmental influences such as rain, dust, dirt, or the like.

[0038] Regardless of the above, the sash can optionally be additionally locked to the frame via one or more locking points in the closed position. For this purpose, one or more locking pins can be provided. The handle, in particular by means of the drive rod, can then be coupled to the at least one locking pin in such a way that the at least one locking pin can be actuated by the handle. This contributes to particularly simple operation of the sash assembly, since the at least one locking pin and the self-locking device can be actuated by the same handle.

[0039] The invention is explained in more detail below with reference to the figures, where identical or functionally equivalent elements are provided with identical reference numerals. The figures 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. 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 made of Figur 1 in a perspective exploded view; Fig. 4a,b an assembly of the opening limiting device and the self-locking device of the sash arrangement with locking element in locked position (view a) and in release position (view b); Fig. 5 the pivot bolt of the self-locking device made of Figur 3 in a perspective view in isolation; Fig. 6 the locking element of the self-locking device made of Figur 3 in a perspective view in isolation; and Figs. 7a-11b show various schematic representations to explain the operation of the opening limiting device and the self-locking device, in each case showing an exemplary opening position of the sash on the right and a corresponding functional position of the opening limiting device or self-locking device in a top view on the left and a corresponding functional position of the switching rod in isolation on the left.

[0040] Figur 1 Figure 1 shows a sash arrangement, which is designated as a whole by the reference numeral 10. The sash arrangement 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 (tilt fitting).

[0041] 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 sash 14 has a lower sash cross member 28, an upper sash cross member 30, and two vertical sash members 32, 34. These define a sash element 36, e.g., a glazed sash panel 36.

[0042] 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. Furthermore, the sash assembly 10 has an opening limiting device 40 with a self-locking device 42, which will be explained in detail below and which is arranged, by way of 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 self-locking devices 42 arranged at different locations between the frame 12 and the sash 14 is also conceivable.

[0043] As explained in detail below, the opening limiting device 40 allows the sash 14 to pivot relative to the frame 12 only up to a defined, partially open position (see figure). Fig. 8b The opening limiting device 40 comprises a pivot arm 44 arranged on the frame side (see figure). Fig. 2 ), a switching rod 46 arranged on the wing side (see Fig. 3 ) and a wing-side guide device 48 (see Fig. 3 ). A limitation of the opening angle of the wing 14 is achieved by the pivot arm 44 engaging with a pin 50 in a guide groove 52 of the guide device 48 which is closed at one end (explained in detail below).

[0044] The Figur 2 Figure 1 shows the swivel arm 44 in isolation. The swivel 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 that is radially wider in cross-section than the shaft section 58. At end 54, the swivel arm 44 has a bearing block 62, by means of which the swivel arm 44 can be attached to the frame 12, e.g., by screwing or clamping. A stop 64 is provided on the bearing block 62, which limits the pivoting movement of the swivel arm 44 relative to the bearing block 62 in the closing direction. A detent 68, actuated by a spring 66, is provided, which holds the swivel arm 44 in the closed position relative to the bearing block 62. If the swivel arm 44 is to be swivelled, the detent 68 must first be overcome.

[0045] The guide device 48 and the switching rod 46 of the opening limiting device 40 are in Fig. 3 shown in detail. The switching rod 46 extends along a longitudinal direction 70. The switching rod 46 is, by way of example and preferably, guided slidably on the wing 14 along the longitudinal direction 70, e.g. in a groove formed on the upper wing cross member 30 (not shown). As shown Fig. 3 As can be seen, the shift rod 46 and the guide device 48 overlap each other at least partially along the longitudinal direction 70.

[0046] A pivot guide 72 is provided on the shift rod 46, which has lateral wall sections 74, 76 projecting beyond the shift rod 46. The wall sections 74, 76 are spaced apart from each other to accommodate the pivot 50, in particular the head section 60 of the pivot 50. In this example, the pivot guide 72 is formed separately from the shift rod 46. In embodiments not shown, however, the pivot guide 72 can also be formed integrally with the shift rod 46.

[0047] The guide device 48 comprises in the example a base body 78 and a guide plate 80 (see Fig. 3 The guide plate 80 is fastened to the base body 78 by means of screws 82, e.g., set screws 82. For this purpose, the guide plate 80 and the base body 78 have corresponding threaded bores 84 for receiving the screws 82. The guide groove 52 mentioned above is formed in the guide plate 80. The guide groove 52 extends along the longitudinal direction 70 and has an open end 86 and a closed end 88.

[0048] In this example, the base body 78 is essentially U-shaped with two legs or walls 90, 92 running parallel to each other along the longitudinal direction 70, between which the pin 50 of the swivel arm 44 can be received. The base body 78 is designed such that the wall sections 74, 76 of the pin guide 72 can be inserted between the legs 90, 92 of the base body 78.

[0049] The base body 78 is fixed to the upper wing cross spar 30 of the wing 14 in a non-sliding manner. Side guide sections 94, 96 are shown as examples (see figure). Fig. 4a ) designed for coupling with a groove arranged on the wing side of the upper wing spar 30. The guide sections 94, 96 are designed to engage behind the lateral groove edges of the wing-side groove.

[0050] As mentioned above, in the partially open position of the wing 14, the pin 50 engages in the guide groove 52 and rests against its closed end 88 (cf. Fig. 8b This limits further pivoting of the wing 14 in the opening direction (away from the frame 12).

[0051] 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 pivot bolt 98 and a locking element 100, which are arranged, by way of example, between the base body 78 and the guide plate 80 (see figure). Fig. 3 ).

[0052] The swivel bolt 98 is pivotably mounted on the guide device 48 about a pivot axis 102 orthogonal, in particular vertical, to the switching rod 46 (see figure). Fig. 4a In the example, the base body 78 has a corresponding pivot bolt receptacle 104 for receiving the pivot bolt 98. The base body 78 also has a projection 106 which engages in a corresponding receptacle 108 of the pivot bolt 98 and thus provides the pivot axis 102 (see also Fig. 4a and 5 The further design of the swivel bolt 98 will be described later in relation to the Figur 5 explained.

[0053] The locking element 100 is guided in a corresponding locking element receptacle 110 on the base body 78 of the guide device 48 and is displaceable along a displacement axis 114 parallel to a width direction 112 of the base body 78 (see figure). Fig. 4a The locking element receptacle 110 has a first stop 116 and a second stop 118, between which the locking element 110 is slidable. As explained in detail below, the locking element 110 assumes a locking position when it rests against the first stop 116 (see Figure 1). Fig. 4a ), and a release position if it is at the second stop 118 (cf. Fig. 4b ).

[0054] The locking element 100 is pre-tensioned in the direction of the locking position by means of a spring 120. The spring 120 is shown, by way of example, in a corresponding spring receptacle 122 of the locking element 100 (see figure). Fig. 6 ).

[0055] As in Figur 6 As shown, the locking element 100 has an engagement section 134, for example in the form of a hook section 134. The pivot bolt 98 has a corresponding locking element receiving section 136 in which the engagement section 134 of the locking element 100 can be received, in particular in a form-fitting manner (see Figure 1). Fig. 5 The pivot bolt 98 also has a receiving section 138 for receiving the pin 50. As explained in more detail below, the pivot bolt 98 can be pivoted about the pivot axis 102 by the interaction of the pin 50 with a first actuating section 140 of the pivot bolt 98 or with a second actuating section 142.

[0056] The locking element 100 interacts with the switching rod 46 in such a way that by moving the switching rod 46 along the longitudinal direction 70, the locking element 100 can be displaced along the displacement axis 114. As shown in Fig. 6 As shown, the locking element 100 has a guide projection 124 which penetrates a corresponding recess 125 in the locking element receptacle 110 of the base body 78 in a vertical direction and, in the assembled state, interacts with a guide contour 126 formed on the switching rod 46 (see figure). Fig. 3 ).

[0057] The guidance contour 126 has a first guidance section 128 and a second guidance section 130 (see Fig. 3 If the guide projection 124 is in contact with the first guide section 128, the locking element 100 is in the release position. If the guide projection 124 is located at the level of the second guide section 130, the locking element 100 is, depending on the position of the pivot bolt 98, either in the locked position or in the clamping position mentioned above (explained in more detail below).

[0058] In order to be able to move the switching rod 46 along the longitudinal direction 70 and thus selectively bring either the first guide section 128 or the second guide section 130 to the level of the guide projection 124, the switching rod 46 is coupled to the handle 38 arranged on the wing side by means of at least one connecting rod (not shown) such that the switching rod 46 can be moved into different switching positions depending on the actuation positions of the handle 38. In the example, the switching rod 46 has a coupling element 132 at each of its ends, to which the connecting rods can be attached.

[0059] The handle 38 can be rotated into different operating positions (e.g., 0°, 90°, 180° positions). The handle 38 is coupled to a (not shown) gear unit, which converts the rotary movement of the handle 38 into a translational movement for the drive rod and thus into a sliding movement of the shift rod 46 along the longitudinal direction 70.

[0060] The operation of the opening limiting device 40 and the self-locking device 42 is explained below using the following: Figuren 7a bis 11b explained.

[0061] Figur 7a The figure shows the wing assembly 10 in the closed position, i.e., the wing 14 is located within the frame 12. The handle 38 is in a first operating position (0° position or closed position). The locking mechanisms (not shown) for securing the wing 14 to the frame 12 are engaged. The wing 14 therefore cannot be pivoted relative to the frame 12.

[0062] As from Figur 7a As can be seen in the left-hand view, the shift rod 46 is in a first switching position corresponding to the first actuation position of the handle 38, in which the locking element 100 with the guide projection 124 rests against the first guide section 128 of the shift rod 46 and is thus displaced against the spring force. The locking element 100 lies in the Fig. 7a shown initial configuration with its engagement section 134 on a clamping section 144 of the swivel bolt 98 (see also Fig. 5 ) so that the swivel bolt 98 is acted upon by the spring action of the locking element 100 with a contact section 146 against a holding section 148 of the base body 78 of the guide device 48 (clamping position of the locking element 100).

[0063] In this configuration, the swivel bolt 98 is in an open position in which an opening of the receiving section 138 points towards the free end 86 of the guide groove 52 (receiving section 138 ready to receive the pin 50).

[0064] The cone 50 is located in Fig. 7a still outside the guide device 48 in the pin guide 72, wherein the lateral wall sections 74, 76 enclose the head section 60 of the pin 50 laterally to the longitudinal direction 70 between themselves (closed position of the wing 14).

[0065] At the in Figur 7b In the configuration shown, the sash 14 is located within the frame 12; however, the handle 38 is rotated 90° counterclockwise compared to the configuration shown in Fig. 5a (second operating position, 90° position). The locking mechanisms (not shown) for securing the sash 14 to the frame 12 are disengaged. The sash 14 can therefore be pivoted relative to the frame 12.

[0066] As from Figur 7b In the left-hand view, the shift rod 46 is in a second switching position corresponding to the second actuation position of the handle 38, in which the shift rod 46 is opposite the one in Figur 7a The position shown is shifted along the longitudinal direction by 70° (in Fig. 7 "to the right"). By relocating the shift rod 46, the pin guide 72 was changed compared to the one in Fig. 7a In the configuration shown, the pin 50 is displaced slightly out of the guide device 48. The pin 50 is located outside the guide device 48 but still within the pin guide 72.

[0067] In the second switching position of the switching rod 46, the locking element 100 is arranged at the level of the second guide section 130 of the switching rod 46, so that the pivoting element 100 could in principle be moved into the locking position (in Fig. 7b (The corresponding position of the locking element in the locked position is shown with dashed lines). However, in the configuration shown, the locking element 100 is held in the clamping position by the pivot bolt 98 (pivot bolt 98 in contact with the holding section 148 of the guide device 48).

[0068] If wing 14 is now started from the in Figur 7b In the configuration shown, when open, the pin 50 slides in the guide groove 52 towards the closed end 88 (to the left in the figures). As shown Fig. 8a As can be seen, when the pin 50 reaches a predetermined position in the system, it comes into contact with the first actuating section 140 of the swivel bolt 98 (see also Fig. 5 ), so that the pivot bolt 98 is pivoted about the pivot axis 102 when the pin 50 is moved further towards the closed end 88 (in Figur 8a clockwise). If the pin 50 rests against the closed end 88 of the guide groove 52 (wing 14 in a partially open position, cf. Fig. 8b ), the swing bolt 98 is in the closed position in which the pin 50 is received in the receiving section 138 of the swing bolt (cf. Fig. 8b ). As soon as the closed position of the swing bolt 98 is reached, the locking element 100 snaps into the locking position by means of the spring action, in which the locking element 100 engages with its engagement section 134 in the locking element receiving section 136 of the swing bolt 98 in a form-fitting manner (locking configuration of the self-locking device 42).

[0069] In this locking configuration, a pivoting movement of the pivot bolt 98 about the pivot axis 102 is blocked, so that the pin 50 is trapped by the receiving section 138 of the pivot bolt 98 and not in the direction of the free end 86 of the guide groove 52 (in Figur 8b The wing 14 can be shifted "to the right". In the partially open position, the self-locking device 42 automatically locks the wing 14.

[0070] To start from the in Figur 8b In order to close the sash 14 again in the configuration shown, i.e., to pivot it from the partially open position to the closed position, the self-locking device 42 must be released. For this purpose, the locking element 100 must first be moved from the locked position to the release position. In the proposed sash arrangement 10, this is achieved by moving the handle 38 from the second operating position (90° position) back to the first operating position (0° position) (see figure). Fig. 9a ).

[0071] As in Fig. 9a , View left, shows the shift rod 46 being returned to the in Fig. 7a The first switching position shown (in the figures "to the left") is moved, in which the locking element 100 with the guide projection 124 rests against the first guide section 128 of the switching rod 46. In contrast to the one shown in Fig. 7a In the configuration shown, however, the swing bolt 98 is held in the closed position by the pin 50 and the locking element 100 is disengaged from the swing bolt 98, so that a pivoting movement of the swing bolt 98 about the pivot axis 102 is no longer blocked by the locking element 100.

[0072] Will the wing 14 be removed from the in Figur 9a When the configuration shown is returned to the closed position, the pin 50 slides from the closed end 88 of the guide groove 52 towards the free end 86 (to the right in the figures). In doing so, the pin 50 engages with the second actuating section 142 of the pivot bolt 98 (see also Fig. 5 ) together and pivots the swivel bolt 98 into the open position (counterclockwise in the figures). As in Figur 9b , View on the left, the locking element 100 then returns to the clamping position described above.

[0073] Before the wing 14 can be completely closed, the handle 38 – at least if interlocks are provided – must be moved once again to the 90° position (second operating position) in order to allow, for example, the engagement of the locking bolts of the interlocks in corresponding locking receptacles (cf. Fig. 10a ). If wing 14 is again in the closed position (cf. Fig. 10b ), the handle 38 can be returned to the first operating position (0° position) to lock the tumblers.

[0074] In Figur 11a The sash 14 is located within the frame 12, however, the handle 38 is pivoted into a third confirmation position (180° position or second opening position). The locking mechanisms (not shown) for securing the sash 14 to the frame 12 are unlocked. The sash 14 can therefore be pivoted relative to the frame 12. In this operating 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, e.g., into a fully open position.

[0075] As from Figur 11a As can be seen in the left-hand view, the switching rod 46 is in a third switching position corresponding to the third actuation position of the handle 38. In this third switching position, the switching rod 46 is shifted even further to the right compared to the 90° switching position shown in Fig. 5b. In this third switching position, the pin guide 72 is spaced so far from the guide device 48 that the pin 50 is located between the guide device 48 and the pin guide 72. Thus, the pin 50 is out of engagement with the guide device 48 and the pin guide 72. If the sash 14 is opened from this configuration, the guide device 48 and the switching rod 46, which are arranged on the sash 14, are pivoted away from the pivot arm 44, which is arranged on the frame 12 (see Fig. 5b). Fig. 11b The wing 14 can therefore be pivoted relative to the frame 12 like a conventional casement wing.

[0076] In the third switching position of the switching rod, the guide projection 124 is arranged at the level of the second guide section 128 of the switching rod 46, whereby the locking element 100 is prevented from being displaced into the locking position by the pivot bolt 98 (clamping position).
