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] EP 4 006 277 A1 (subsequently published) discloses a wing arrangement comprising a frame, pivoting wing, a handle, a guide body, a pivoting arm and an opening limiting device with a self-locking device.

[0004] 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.

[0005] 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.

[0006] 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.

[0007] The switching rod is guided so that it can slide along a longitudinal direction on the sash. For example, the sash can have a groove for guiding the switching rod. The groove can have lateral groove edges that project into the clear cross-section of the sash-side groove and engage guide sections projecting laterally from the switching rod when the switching rod is positioned in the groove.

[0008] 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 axis. 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 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, for example, for the drive rods.

[0009] 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 that is closed at one end is formed in the at least one guide part.

[0010] The swivel arm is pivotally mounted to the frame at one end. For example, the swivel arm may have a bearing block at one end, which allows it to be attached to the frame (fixed frame), e.g., 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, e.g., spring-loaded, may be provided to hold the swivel arm in the closed position.

[0011] 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.

[0012] 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. In particular, the self-locking device may be designed to automatically lock the pivot only when the pivot 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. In other words, 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.

[0015] For example, it is 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, such as additional levers or buttons, to release the self-locking mechanism. This also contributes to a simple and cost-effective design of the wing assembly.

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

[0017] Self-actuation of the self-locking device can be achieved, in particular, by pre-tensioning the locking element into the locking position, especially by spring tension. In this respect, the locking element can be biased in the direction of the position that blocks the pin. For example, it is conceivable that when the pin rests against the closed end of the guide groove (i.e., when the sash is in the partially open position), the pre-tension moves the locking element from the release position into the locking position.

[0018] For particularly easy operation, it can also be advantageous if the locking element interacts directly or indirectly with the switching rod in such a way that the locking element can be moved from the locked position to the released position by sliding the switching rod along its longitudinal direction. In this way, the locking element can be mechanically moved into the released position by actuating the handle. Such a design enables reliable and intuitive operation of the self-locking device and is also cost-effective.

[0019] In an advantageous embodiment, the guide groove can have a straight groove section adjoining the open end and, at its closed end, a locking recess laterally offset from the straight groove section. The guide groove can thus be curved at its closed end. In the partially open position of the sash, the pin rests against this locking recess, preventing the sash from opening beyond the partially open position. The locking element can then be designed such that, in the locked position, it engages the pin resting in the locking recess. With such an embodiment, the sash can be secured in the partially open position in a particularly reliable and stable manner, preventing it from being forced into the closed or fully open position, even under comparatively high force.It is conceivable that both the straight groove section and the detent recess are formed in the same component. It is further conceivable that the guide device is designed in two parts, in particular comprising two axially successive guide sections. Then, for example, the straight groove section can be formed in a first guide section and the detent recess in a second guide section, which facilitates simple manufacturing.

[0020] According to the invention, the locking element is designed as a sliding bolt. The sliding bolt can be guided translationally along a sliding axis parallel to the longitudinal direction on the guide device. Depending on its sliding position along the sliding axis, the sliding bolt can assume a locking position that blocks the pin in the guide groove, particularly in the detent recess, or a release position that no longer locks or releases the pin. In particular, the sliding bolt can be designed such that it locks the pin against movement out of the detent recess when the pin is in contact with it. For example, it is conceivable that the sliding bolt clamps the pin in the detent recess.

[0021] The sliding bolt can preferably be pre-tensioned into the locking position, particularly by means of a spring mechanism. In this respect, the sliding bolt can be biased in the direction of the position that blocks the pin. For example, it is conceivable that when the pin rests in the laterally offset detent recess (i.e., when the sash is in the partially open position), the sliding bolt is moved from the release position to the locking position by the pre-tension.

[0022] Specifically, the sliding bolt can be arranged in the path of movement of the pivot arm's pin from the free end of the guide groove to the closed end or the detent recess. In particular, the sliding bolt can be designed and arranged in the locking position such that, during a movement of the pin from the free end of the guide groove to the closed end of the guide groove (i.e., when the sash pivots from the closed position to the partially open position), the sliding bolt can be displaced by the pin against the preload in the direction of the release position. When the pin rests in the detent recess, the sliding bolt can then preferably be automatically returned to the locking position by the preload.In other words, when the sash is opened from the closed position, the sliding bolt can first be pushed back into the release position by the pin against the preload, and then, when the pin rests in the laterally offset detent recess, snaps back into the locking position due to the preload.

[0023] The sliding bolt can preferably interact with the switching rod in such a way that the sliding bolt can be moved from the locked position to the release position by actuating the switching rod. Specifically, the sliding bolt can have a guide projection that engages in a section of the switching rod. The section of engagement can be designed and interact with the guide projection in such a way that the sliding bolt can be moved between the locked and release positions by moving the switching rod along its longitudinal axis. For example, the guide projection can interact with an axial boundary wall of the section of engagement, and in particular, bear against it, depending on the switching position of the switching rod.

[0024] Preferably, the engagement section extends longitudinally along the longitudinal direction. For example, it is conceivable that the engagement section is formed as a local recess on the upper side of the switching rod facing the guide projection. It is also conceivable that the switching rod has a local recess, for example in the form of an elongated hole. In particular, the guide section interacts directly with the switching rod, which promotes reliable actuation with low structural complexity. It is conceivable that the sliding bolt is guided within the guide device, for example within a guide element. In this case, the guide device or guide element can have a recess, z.B. The guide projection has an elongated hole through which it penetrates. An axial boundary wall of the recess or elongated hole in the guide device or guide element can simultaneously form a stop for the guide projection, limiting the displacement of the sliding bolt along its axis. The guide projection can be formed integrally with other sections of the sliding bolt. It is also conceivable that the guide projection is provided separately, for example, by a screw.

[0025] Advantageously, the switching rod can be designed and coupled to the handle in such a way that, depending on the operating position of the handle, the switching rod can assume different switching positions, so that the guide projection and thus the sliding bolt can be moved between the release position and the locking position by actuating the handle. Advantageously, when the handle is in a first operating position (e.g., 0° position or closed position), the switching rod can be in a first switching position in which the sliding bolt interacts with the switching rod, in particular the guide projection with an axial limiting wall of the engagement section, such that the sliding bolt is in the release position.Therefore, by moving the handle into this first operating position, particularly from a second operating position explained below, the locking of the pin by the sliding bolt can be released. When the pin rests against the closed end of the guide groove or in the detent recess (i.e., the sash is in the partially open position), the pin can then be moved out of the guide groove.

[0026] 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 sliding bolt interacts with the switching rod, and in particular the guide projection interacts with the engagement section of the switching rod, such that the sliding bolt is in the locking position. For example, it is conceivable that the guide projection in the second switching position of the switching rod is spaced so far from the boundary wall of the engagement section described above that the sliding bolt can be moved, or is moved, into the locking position by the preload along the sliding axis.

[0027] In an advantageous embodiment, the guide device can comprise a one- or multi-part guide component in which a straight groove section and a receiving section adjoining the straight groove section are formed. The guide device can also include a curved guide component, which has a guide contour, particularly an arc-shaped one. The curved guide component is inserted or can be inserted into the receiving section in such a way that the guide contour, together with a boundary wall of the receiving section of the guide component, forms the locking recess. In this respect, the locking recess is not provided by a single component, but by the interaction of two components, namely the guide component and the curved guide component.

[0028] In such a design, the sliding bolt can be guided translationally along the sliding axis within the curve guide element. For example, it is conceivable that the curve guide element has a corresponding receptacle for the sliding bolt.

[0029] To allow for flexible use of the sash arrangement, it is advantageous if the sash can be hinged on the frame on either the left or right side. 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.

[0030] In a design with a curved guide element, it can be advantageous for this purpose if the curved guide element can be inserted into the guide component in two different orientations that are 180° opposite to each other. In particular, the curved guide element can have two guide contours that are mirror images of each other. The curved guide element can thus be easily mounted on the guide component in two opposite positions for use on right- or left-hinged wing assemblies. Furthermore, it can be advantageous if the receiving section of the guide component is symmetrical about a central longitudinal plane of the guide component, with the central longitudinal axis extending orthogonally to the width direction of the guide component and running centrally in the guide groove in the width direction.Furthermore, it can be advantageous if the sliding bolt and the curve guide part are designed in such a way that the sliding bolt can be inserted into the curve guide part in two different orientations opposite each other by 180°, in particular by a central longitudinal axis of the sliding bolt.

[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 or guide part 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. Furthermore, it promotes a more robust design.

[0033] Alternatively, the pivot guide can be designed separately from the shift rod and mounted on it, in particular by being placed directly onto the shift rod. 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.

[0034] Advantageously, the guide groove of the guide device can be laterally bounded by walls, with the pin guide being designed such that it can be inserted between the walls into the guide groove. This facilitates a compact and flexible design of the opening limiting device.

[0035] 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.

[0036] 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 limiting device 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 limiting device is effective (i.e., a pivoting movement of the wing from the closed position is limited to a partially open position), or whether the wing can be opened beyond this partially open position, for example in a maximum open position.

[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 a schematic representation of a wing arrangement; Fig. 2 shows a representation of a pivot arm of the opening limiting device. Figur 1 in a perspective view in isolation; Fig. 3 an assembly of an embodiment of the opening limiting device and the self-locking device in a perspective exploded view; Fig. 4a,b the assembly made of Figur 3 in a perspective view from above (view a) and from below (view b); Figs. 5a-9b show various schematic representations to illustrate the operation of the opening limiting device and the self-locking device, with an exemplary opening position of the sash shown on the right and a corresponding functional position of the opening limiting device or self-locking device shown on the left in a top view (top left view) and a side view (bottom left view); Fig. 10a shows an assembly of a further embodiment of the opening limiting device and the self-locking device of the sash assembly in a perspective exploded view in various installation states; and Figs. 11a, b show the assembly of Figur 10a in a perspective view from above (view a) and from below (view b).

[0040] Figur 1 Figure 1 shows a sash arrangement, which is designated overall 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). As explained above, 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. It is also conceivable to use two opening limiting devices 40 with self-locking devices 42 arranged at different locations between the frame 12 and the sash 14.

[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. 5a bis 6b 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 The guide device 48, shown in detail, comprises two guide elements 72, 74 arranged axially along a longitudinal direction 70, one behind the other, each of which has groove sections 76, 80. The groove sections 76, 80 together form the aforementioned closed-ended guide groove 52.

[0046] Specifically, the first guide part 72 has a straight groove section 76 which adjoins the open end 82 of the guide groove 52 and extends along the longitudinal direction 70. The second guide part 74 has a locking recess 84 for receiving the bolt 50 or the shank section 58 of the bolt 50, which, in the assembled state of the guide parts 72, 74, is arranged laterally offset with respect to the straight groove section 76 (see also Fig. 5a The locking recess 84 defines a closed end 86 of the guide groove 52.

[0047] The guide elements 72, 74, can each be designed as one or more parts. As in Fig. 3 As indicated, the second guide element 74 can, for example, be designed in two parts, comprising a base body 88 and a guide plate 90 inserted into the base body 88, in which the detent recess 84 is formed. It is also conceivable that the guide groove 52 is formed in a single component. The guide groove 52 is laterally bounded by walls 92, 94.

[0048] The guide elements 72, 74 are fixed to the upper frame cross member 30 of the sash 14 in a non-sliding manner. For example, lateral guide sections 96, 98 are formed on the respective walls 92, 94 for coupling with a groove arranged on the sash side of the upper sash cross member 30 (see figure). Fig. 4a The guide sections 96, 98 are designed to engage the lateral groove edges of the wing-side groove. Threaded bores 100 are provided on the guide parts 72, 74 to fasten the respective guide part 72, 74 to the wing-side groove. For example, the threaded bores 100 can accommodate screws, e.g., set screws, to clamp the guide part 72, 74 relative to the wing-side groove.

[0049] The switching rod 46 is slidably guided on the wing 14 along the longitudinal direction 70, for example and preferably in a groove formed on the upper frame cross member 30 of the wing 14 (not shown). As shown Fig. 3 As can be seen, the shift rod 46 and the guide parts 72, 74 overlap each other at least partially along the longitudinal direction 70.

[0050] A pivot guide 102 is provided on the switching rod 46, which has lateral wall sections 104, 106 projecting beyond the switching rod 46. The wall sections 104, 106 are spaced apart from each other in such a way as to accommodate the pins 50, in particular a head section 60 of the pin 50 of the pivot arm 44, between them. In the example, the pivot guide 102 is formed separately from the switching rod 46 and is connected to the switching rod 46 via corresponding coupling elements 108 (see Figure 1). Fig. 4b In embodiments not shown, the pin guide 102 can also be formed integrally with the switching rod 46. The pin guide 102 is designed such that the wall sections 104, 106 can be inserted between the walls 92, 94 into the first guide part 72.

[0051] As mentioned above, in the partially open position of the wing 14, the pin 50 engages in the guide groove 52 and rests in the locking recess 84 (see above). Figur 6b This limits further pivoting of the wing 14 in the opening direction (away from the frame 12).

[0052] To automatically lock the sash in this partially open position, the aforementioned self-locking device 42 is provided. The self-locking device 42 comprises a locking element 110, which in this example is designed as a sliding bolt 112 (see figure). Fig. 3 The sliding bolt 112 is located in the Figuren 3 bis 4b In the illustrated embodiment, the second guide part 74 is guided in a corresponding receptacle 114 and can be translationally displaced along a displacement axis 116 parallel to the longitudinal direction 70. Depending on its displacement position along the displacement axis 116, the displacement bolt 112 can assume a locking position that locks the pin 50 in the detent recess 84 or a release position that does not lock or releases the pin 50 (explained in detail below).

[0053] As from Fig. 3 As can be seen, the sliding bolt 112 in the example is L-shaped, with the thin leg 118 forming a locking section 118. With the locking section 118, the sliding bolt 112 can then, when the pin 50 is arranged in the detent recess 84, slide laterally past the pin 50, in particular past the shaft section 58, so that the pin 50 is clamped between the detent recess 84 and the locking section 118 (locking position, cf. Fig. 6b ).

[0054] As in Fig. 3 As shown, the sliding bolt 112 is acted upon in this locking position by means of a spring 120. By way of example, the spring 120 is held by a bolt 122 on a retaining element 124, which can be received in the receptacle 114 and fixed there, in particular by a detent. The spring 120 is in contact with, in particular connected to, the sliding bolt 112 at one end, and is supported at its other end by the retaining element 124.

[0055] The sliding bolt 112 has a guide projection 126, which is located in the Figuren 3 bis 4b The example shown is provided by a screw 128 with a screw head 132. As shown Figur 4b As can be seen, the guide section 126 or the screw 128, in the assembled state, penetrates a recess 130 formed in the second guide part 74, in particular in the form of an elongated hole 130. An axial limiting wall 138 of the recess 130 in the guide part 74 forms a stop 138 for the guide projection 126 or the screw head 132, so that a displacement path of the sliding bolt 112 along the displacement axis 116 is limited (anti-loss device).

[0056] The screw 128 (guide section 126) also engages in a recess 134 formed in the shift rod 46, in particular in the form of an elongated hole 134. The recess 134 in the shift rod 46 thus forms an engagement section 136 for the guide projection 126 or the screw head 132.

[0057] Depending on the displacement position of the switching rod 46 along the longitudinal direction 70, the guide projection 126 or the screw head 132 can engage with an axial limiting wall 140 of the engagement section 136 (cf. Fig. 4b ) interact so that the sliding bolt 112 can be displaced from the locking position against the preload of the spring 120 and thus moved into a release position. In the release position, the locking section 118 of the sliding bolt 112 is retracted against the spring preload in such a way (in Fig. 3 "to the left"), so that the pin 50 can be moved out of the locking recess 84.

[0058] In other words, by moving the switching rod 46 along the longitudinal direction 70, the locking element 110 can be shifted between the release position and the sliding position. For this purpose, 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 142 at each of its ends, to which the connecting rods can be attached via corresponding connecting rod coupling elements 144 (see figure). Fig. 4a ).

[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 functionality of the wing arrangement 10 is explained below using the following examples. Figuren 5a bis 9b explained.

[0061] Figur 5a 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 5a As can be seen in the lower left view, the switching rod 46 is in a first switching position corresponding to the first actuation position of the handle 38. In this position, the guide projection 126 or the screw head 132 is in contact with the axial limiting wall 140 of the engagement section 136 of the switching rod 46, so that the sliding bolt 112 is in the release position against the spring preload. In this configuration, the pin 50 is located outside the guide groove 52 in the pin guide 102, with the lateral wall sections 104, 106 enclosing the head section 60 of the pin 50 laterally in the longitudinal direction 70.

[0063] At the in Figur 5b In the configuration shown, the wing 14 is located within the frame 12, however, the handle 38 is opposite to the one shown in Fig. 5a The configuration shown is rotated 90° counterclockwise (second operating position, 90° position). The (not shown) locking mechanisms for the sash 14 on the frame 12 are unlocked. The sash 14 can therefore be pivoted relative to the frame 12.

[0064] As from Figur 5b In the lower left view, it can be seen that 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 5a The position shown is shifted along the longitudinal direction by 70° (in Fig. 5 "to the right"). In this second switching position of the switching rod 46, the axial limiting wall 140 of the engagement section 136 is positioned so far in the direction of the spring action (in Fig. 5 "to the right") so that the sliding bolt 112 is in the locking position described above due to the application of pressure.

[0065] Furthermore, the relocation of the shift rod 46 improved the pin guide 102 compared to the one in Fig. 5a In the configuration shown, the pin 50 is displaced slightly out of the guide part 72. The pin 50 is located outside the guide part 72 and still within the pin guide 102, with the lateral wall sections 104, 106 enclosing the head section 60 of the pin 50 laterally to the longitudinal direction 70.

[0066] If wing 14 is now started from the one in Figur 5b In the configuration shown, the pin 50 slides in the guide groove 52 towards the closed end 86 (cf. Fig. 6a ). As from Fig. 6a As can be seen in the lower left view, the pin 50 pushes the sliding bolt 112 against the spring preload towards the release position until the pin 50 reaches the detent recess 84 and is pulled into the detent recess 84 by laterally acting force components transmitted via the pivot arm 40. When the pin 50 rests in the laterally offset detent recess 84, the sliding bolt 112 is returned to the locking position by the spring action (into the Figuren 5a bis 9b shifted "to the right").

[0067] As from Fig. 6b , View below left, it can be seen that the pin 50 is then trapped between the detent recess 84 and the locking section 118 of the sliding bolt 112, so that the pin 50 does not move towards the free end 82 of the guide groove 52 (in Fig. 6b "to the right") and thus cannot be moved out of the guide groove 52. The wing 14 is therefore automatically locked in the partially open position by the self-locking device 42.

[0068] To start from the in Figur 6b In order to close the sash 14 in the configuration shown, i.e., to pivot it from the partially open position to the closed position, the self-locking device 42 must first be released. In other words, the sliding bolt 112 must be moved from the locking position to the release position. With 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. 7a ). As in Fig. 7a , View bottom left, shows how the shift rod 46 is then put back into the Fig. 5a The switch position shown is shifted (to the left in the figures), in which the sliding bolt 112 is in the release position. In the release position, the pin 50 can then be moved out of the detent recess 84 (see figure). Fig. 7b ) and thus wing 14 can be closed again.

[0069] Before the wing 14 can be completely closed again, the handle 38 – at least if interlocks are provided – must be moved once more to the 90° position (second operating position) after the pin has left the detent recess, in order to enable, for example, the engagement of locking bolts in corresponding locking receptacles of the interlocks (cf. Fig. 8a ). If wing 14 is again in the closed position (cf. Fig. 8b ), the handle 38 can then be moved into the first operating position (0° position) in order to lock the tumblers (cf. Fig. 5a ).

[0070] In Figur 9a 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, for example, into a fully open position.

[0071] As from Figur 9a As can be seen in the lower left view, the switching rod 46 is in a third switching position corresponding to the third actuation position of the handle 38. In this position, the switching rod 46 is shifted even further to the right compared to the 90° switching position, so that the pin guide 102 is spaced so far from the guide part 70 that the pin 50 is located between the guide part 72 and the pin guide 102. Thus, the head section 60, or rather the pin 50, is out of engagement with the guide part 72 and the pin guide 102. If the sash 14 is opened from this configuration, the guide parts 72, 74, 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 figure). Fig. 9b The wing 14 can therefore be pivoted relative to the frame 12 like a conventional casement wing.

[0072] The Figuren 10a bis 11b Figure 1 shows a further possible embodiment of the opening limiting device 40 and the self-locking device 42. The switching rod 46 and the pin guide 102 largely correspond to the switching rod 46 and pin guide 102 described above, respectively, so that reference is made to the descriptions therein to avoid repetition.

[0073] In contrast to the design described above, the guide device 48 comprises the one described in the Figuren 10a bis 11b In the illustrated example, a guide component 146 is formed in which a straight groove section 76 (forming the straight groove section 76 of the guide groove 52) and a receiving section 148 adjoining the straight groove section 76 are formed. The receiving section 148 is, by way of example and preferably, mirror-symmetrical to a central longitudinal plane of the guide groove 52, which extends orthogonally to a width direction 149 of the guide groove 52 and runs centrally in the guide groove 52 in the width direction 149 (cf. Fig. 11a ).

[0074] The guide component 146 is similar to the one above in relation to the Fig. 3 bis 4b The described guide elements 72, 74 are fixed non-slidably to the upper frame cross member 30 of the wing 14 via lateral guide sections 96, 98. As described Fig. 10a As can be seen, the guide component 146 also has threaded holes 100 for receiving screws in order to fasten the guide component 146 to the wing-side groove.

[0075] As from Fig. 10a As can be seen, the guide device 48 also includes a cam guide element 150, which can be inserted into the receiving section 148 of the guide component 146. The cam guide element 150 has a contour section 152 on its upper side facing away from the switching rod 46, which provides a guide contour 154, in this example an arc-shaped one. Preferably, the contour section 152 has two mirror-symmetrical guide contours 154, 154'. As can be seen from Figur 11a As can be seen, the curve guide part 150 can be inserted or is inserted into the receiving section 148 of the guide component 146 in such a way that the guide contour 154 together with a limiting wall 156 of the receiving section 148 forms the locking recess 84.

[0076] The curve guide part 150 has a receptacle 158 for the sliding bolt 112, in which the sliding bolt 112 is guided slidably along the sliding axis 116 (see figure). Fig. 10a In this embodiment, the guide projection 126 described above is provided by a control element 160 that is separate from the sliding bolt 112. The control element 160 has a base body 162 and a pin section 164 that engages in the engagement section 136 of the switching rod 46.

[0077] As in Figur 10a As shown, the base body 162 of the control element 160 has two projections 170 extending towards the sliding bolt 112. In the assembled state of the wing assembly 10, the projections 170 engage in corresponding receptacles 172 of the sliding bolt 112, for example, such that, on the one hand, a sliding movement of the sliding bolt 112 along the longitudinal direction 70 is limited, and on the other hand, a sliding movement of the control element 160 (e.g., driven by the switching rod 46) can be transmitted to the sliding bolt 112.

[0078] When installed as intended, the control element 160 is inserted into the guide element 146 together with the base body 162 and slidably held there. Preferably, the control element 160 can be guided in the guide element 146 by means of lugs 166 in corresponding receptacles 168. In particular, the control element 160, the sliding bolt 112, and the cam guide element 150 can then be held securely in the guide element 146 by means of the lugs 166 and the receptacles 168.

[0079] Figur 10b shows another possible design option, whereas in contrast to the one in Figur 10a In the arrangement shown, the curve guide part 150 is rotated by 180° about an axis orthogonal to a plane containing the contour section 152, and the sliding bolt 112 is rotated by 180° about its central longitudinal axis.

[0080] The functioning of the design according to Figuren 10a bis 11b, largely corresponds to the functionality explained above, so reference is made to the explanations given there to avoid repetition.
