Description

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

A wing assembly with features of the preamble of claim 1 is from EP 3 363 976 A1 known. There, a rotation-limiting arrangement is provided on a window with a frame and a sash, with a rotary movement limiter being provided in an opening with a rotatable blocking element, 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 rotary movement limiter. The sash is then locked in a partially open position relative to the frame.

The invention is based on the object of providing a reliable rotary opening limitation on a sash arrangement with simple structural means, in which the risk of incorrect operation is reduced. The simplest possible operation is desirable.

The invention solves this problem by a casement arrangement with the features of claim 1. The casement arrangement has a frame (fixed frame) and a casement of a door or window pivotally mounted on the frame.

An opening limiting device is provided which allows the sash to be pivoted relative to the frame, in particular starting from a closed position of the sash, only up to a defined, partially open position (pivoting of the sash is limited from the closed position in the opening direction). The opening-limiting device includes a switching rod, a guide device and a swivel arm.

The shift rod is slidably guided along a longitudinal direction on the wing. For example, the wing can have a groove for guiding the shift rod. The groove can have lateral groove edges that protrude into the clear cross section of the wing-side groove and engage behind guide sections that protrude laterally from the shift rod when the shift rod is arranged in the groove.

The shift rod is coupled by means of a connecting rod with a handle arranged on the wing side in such a way that by actuating the handle, the switching rod can be displaced along the longitudinal direction. In particular, the switching rod can be brought into different switching positions depending on the operating positions of the handle. Thus, defined actuating positions of the handle (e.g. closed position (e.g. 0° position), first open position (e.g. 90° position) and second open 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 which converts the rotary movement of the handle into a translatory movement, for example for the drive rods.

The guide device is fixed to the wing (not movable). The shift rod and the guide device are arranged in such a way that they at least partially overlap one another 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 can comprise or consist of one or more guide parts. For example, it is conceivable that a groove closed on one side is formed in the at least one guide part.

The swing arm is pivotally mounted to the frame at one end. For example, the swivel arm can have a bearing block at one end, by means of which the swivel arm can be attached to the frame (Fixed frame) can be fastened, e.g. by clamping or screwing the bearing block to the frame. The swivel arm can then be pivotable relative to the bearing block. One or more stops can be provided on the bearing block, which limit a pivoting movement of the pivot arm in the closing direction (closed position). A detent, for example acted upon by a spring, can be provided which holds the swivel arm in the closed position.

At its other end, the swivel arm has a pin which engages in the guide groove of the guide device at least when the wing is in the partially open position. In the partially open position, the pin rests against the closed end of the guide groove, as a result of which pivoting of the wing in the opening direction beyond the partially open position is limited. In this respect, further pivoting of the sash away from the frame in the opening direction is blocked.

The wing assembly also includes a self-locking device adapted to automatically lock the spigot such that at least when the spigot is abutting the closed end of the guide groove (i.e., when the wing is in the partially open position), it is in the guide groove is trapped (ie displacement of the pin out of the guide groove is blocked). In other words, the self-locking device is set up to automatically or automatically lock the sash relative to the frame in the partially open position.

In particular, the self-locking device can be set up to automatically lock the pin, in particular only then, when the pin is in contact with the closed end of the guide groove.

Such an embodiment makes it possible to achieve reliable opening limitation with simple structural means. In addition, because the sash is automatically locked in the partially open position, the risk of incorrect operation can be minimized. In particular, the sash can be prevented from being pivoted from the partially open position to the closed position, e.g. in the event of a gust of wind. It can therefore be ensured that a sash that is only partially open, for example for ventilation, is secured in this position.

In order to be able to move the sash back from the partially open position 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 in such a way that the locking of the pin can be released again by actuating the handle, so that the pin can be displaced 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 set up in such a way that, by actuating the handle, it can be moved from the locking configuration that locks the pin to a configuration that no longer locks or releases the pin Release configuration can be converted, in which the pin can be moved out of the guide groove. For example, it is conceivable that the self-locking device interacts with the handle in such a way that the locking of the pin is released again by moving the handle from one operating position, e.g. the 90° position, to another operating position (e.g. the 0° position). can. Such a configuration enables a particularly simple and intuitive operation of the wing arrangement. In particular, it is not necessary to provide additional switching elements, for example additional levers or buttons, in order to release the self-locking device again. This also contributes to a simple and cost-effective design of the wing arrangement.

In the context of an advantageous embodiment, the self-locking device can include a swivel bolt. The swivel bolt can be mounted on the guide device so that it can swivel about a preferably vertical swivel axis that is oriented in particular orthogonally to the switching rod and the longitudinal direction. In particular, depending on its pivot position, the swivel bolt can assume a closed position that catches the pin in the guide groove or an open position that releases the pin. In the closed position, the swivel bolt preferably encompasses the pivot of the swivel arm at least in sections. In the open position, the swivel bolt can preferably be arranged in such a way that the pin is released, in particular from the Guide groove can be shifted out. Such a swivel bolt promotes effective locking and is also comparatively simple and inexpensive to produce.

In concrete terms, the swivel lock can have a receiving section for receiving the pin of the swivel arm, in particular in a form-fitting manner, at least in sections. The receiving section can be designed in such a way that it can encompass the pin in sections along its circumference. In particular, the pin bears against this receiving section in the closed position of the swivel bolt. In this respect, the pin can be caught by the pivot bolt in the closed position of the pivot bolt. In the open position, the swivel lock can be arranged or oriented in such a way that the receiving section releases the pin. The receiving section can expediently be adapted to a pin contour, e.g. have a negative shape of an outer surface of the pin (e.g. in the shape of a segment of a circle).

Advantageously, the swivel lock can be arranged in a movement path of the pivot of the swivel arm from the open end of the guide groove to the closed end of the guide groove. In particular, the pivoting bolt can be designed and/or arranged in such a way that the pivoting bolt can, in the course of a movement of the pin from the free end of the guide groove to the closed end (i.e. when the sash is pivoted from the closed position to the partially open position) can be transferred or is transferred by the pin from the open position into the closed position. In this respect, the pin can pivot the pivot bolt about the pivot axis in the course of its movement from the open end to the closed end of the guide groove. For example, the pin can interact with an actuation section of the receiving section and thus pivot the swivel bolt. The swivel lock can preferably be designed and arranged in such a way that it is also pivoted by the pin when the pin moves in the opposite direction, i.e. from the closed end to the open end of the guide groove, in particular it is transferred from the closed position to the open position . A displacement of the swivel bolt between the open position and the closed position can be achieved by moving the pin.

In order to lock the swivel bolt in the closed position and thus effectively catch the pin in the guide groove, it is fundamentally conceivable that the swivel bolt in the closed position interacts with a contact section of the guide device in a non-positive and/or positive manner and thus exerts a certain retaining force on the pin exercises In the context of a preferred embodiment, the self-locking device can comprise a spring-loaded locking element. The blocking member is preferably designed in such a way that, when the swivel bolt is in the closed position, it automatically assumes a blocking position as a result of the spring preload, in which a Pivoting movement of the pivoting bolt from the closed position to the open position, in particular a pivoting movement about the pivot axis at all, is blocked. The self-locking device can be set up in such a way that the swivel bolt is locked automatically in the closed position by the spring-loaded locking member. Then the pin is securely locked in the guide groove (locking configuration of the self-locking device).

In concrete terms, the locking member can interact with an engagement section in a form-fitting manner with a corresponding locking member receiving section of the pivot bolt. In particular, when the swivel bolt is in the closed position and the blocking member is in the blocking position, the engagement section can engage in a form-fitting manner in the blocking member receiving section. Such a design promotes an effective locking of the pin, so that the wing is securely locked in the partially open position even when a comparatively large force is applied.

In order to be able to release the pin from the locking configuration again (e.g. to convert the leaf from the partially open position to the closed position again), it is necessary to convert the locking member from the locking position to a release position in which the locking member disengages from is the pivot bolt and/or a pivoting movement of the pivot bolt allows. For this purpose, it can be advantageous if the locking member can be driven by the shift rod.

In particular, the locking member can interact directly or indirectly with the shift rod in such a way that the locking member can be transferred from the locked position to the release position by moving the shift rod along the longitudinal direction, ie by actuating the handle. In this respect, the blocking member can block or allow a pivoting movement of the pivot bolt about the pivot axis, depending on a shift position or displacement position of the shift rod. Such an embodiment enables the self-locking device to be actuated reliably and intuitively and is also constructed in a cost-effective manner.

In concrete terms, the blocking member can be guided on the guide device in a translationally displaceable manner between the blocking position and the release position. In this respect, the blocking member can assume a blocking position and a release position, with the blocking member in the blocking position interacting 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 a pivoting movement of the Swing bolt allows.

In order to automatically shift the locking member into the locking position (and thus automatically lock the sash in the partially open position), the locking member can be Be biased toward the locked position. The blocking member can preferably be spring-loaded in the direction of the blocking position. In this respect, the blocking member can be acted upon in the direction of the position that blocks the swivel bolt and thus locks the pin when it rests against the closed end of the guide groove. For example, it is conceivable that the blocking member is transferred into the blocking position by the pretension when the swivel bolt is in the closed position (pin at the closed end of the guide groove, wing in a partially open position).

It is also conceivable that the locking member assumes a clamping position when the pivoting bolt is in the open position, in which the locking member presses the pivoting bolt into the open position. In this respect, the pivoting bolt can be held in the clamped position by the locking member in the open position, so that the pivoting bolt cannot be unintentionally transferred into the closed position. In particular, the blocking member can be located between the release position and the blocking position in the clamping position.

The blocking member can expediently have an engagement section, in particular the engagement section described above, which can be engaged or disengaged with the swivel bolt in such a way that a pivoting movement of the swivel bolt about the pivot axis is selectively blocked or permitted, in particular released. For a special one 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 portion is designed as a hook portion which can positively engage in a corresponding locking member receiving portion of the pivot bolt.

The blocking member can expediently have a guide projection which interacts with a guide contour formed on the shift rod, so that the blocking member can be selectively transferred to the locked position or to the release position by moving the shift rod in the 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, have been formed in the shift rod by a material-removing process, which promotes particularly simple and cost-effective manufacture.

Specifically, the guide contour can have a first guide section and a second guide section. The first guide section can preferably be designed in such a way that when the guide projection is at the level of the first guide section, in particular interacts with the first guide section, preferably is in contact, the blocking member is in the release position. The second The guide section can preferably be designed in such a way that when the guide projection is level with the second guide section, the locking member can be transferred into the locked position (but is perhaps prevented from being transferred by the swivel bolt) or is in the locked position (in particular when the swing bolt is in the closed position).

The shift rod can expediently be designed and coupled to the handle in such a way that, depending on an 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.

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 interacts with the first guide section of the switching rod, so that the Locking element is in the release position, in particular is disengaged from the pivot bolt. In this respect, by moving the handle into the first operating position, in particular from a second operating position explained below, locking of the pivoting bolt and thus locking of the pin by the pivoting bolt can be released. The pin can then be moved out of its abutment on the closed end of the guide groove towards the free end of the guide groove and in doing so, transfer the swing bolt from the closed position to the open position.

Advantageously, when the handle is in a second operating position (e.g. the 90° position), the shift rod can be in a second shift position in which the guide projection is arranged at the level of the second guide section of the shift rod. Preferably, the locking member is then in engagement with the pivot bolt. For example, it is possible that the swing 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 blocking element can be in the blocking position, in particular with the engagement section engaging in the corresponding blocking element receiving section (locking configuration). It is also possible that the swivel bolt is in the open position. Then, when the handle is in the second operating position, the blocking member can assume the above-mentioned clamping position, in which the blocking member is pressed against the pivoting bolt and prevents it from pivoting about the pivot axis (but without being in the blocking position itself).

Expediently, a pin guide can be provided on the shift rod, which has lateral wall sections projecting beyond the shift rod. The wall sections are in particular from each other such spaced to receive between them the pin, particularly a head portion of the pin. The pin guide guides the pin at least in one switching position or in two switching positions of the switching rod, in particular in the first and second switching position explained above, laterally to the longitudinal direction of the switching rod when the pin is 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 when the wing is opened from the closed position and the pin moves towards the closed end of the guide groove .

In concrete terms, the pin guide can be designed in one piece with the shift rod (e.g. made of the same material). This reduces the number of components to design, to manufacture and to assemble. In addition, a stable configuration is hereby promoted. As an alternative to this, the pin guide can be designed separately from the shift rod and can be mounted on the shift rod, in particular can be placed on the shift rod. A separate configuration simplifies the construction of the shift rod. In addition, this allows the use of different materials for the shift rod and pin guide.

In concrete terms, the guide device can extend along a central longitudinal direction and through laterally Be limited walls, the pin guide is designed such that the pin guide can be inserted between the walls in the guide device. This favors a compact and flexible configuration of the opening-limiting device.

The handle can expediently have a third operating position, in particular the 180° position. When the handle is in this third operating position, the switching rod can preferably be in a third switching position in which the pin of the swivel arm is outside the guide device and outside the pin guide, in particular between the guide device and the pin guide. The wing can then be pivoted relative to the frame between the closed position and an open position in which the wing is more open than in the partially open position. In this respect, the wing arrangement can be set up in such a way that the opening limiting device no longer limits a wing opening in the third operating position of the handle. With such a wing arrangement, it is possible to decide whether the opening limiting device is active (i.e. a pivoting movement of the wing from the closed position to a partially open position is limited) simply by actuating the handle, or whether the wing is to move past this partially open position Can also be opened, for example. In a maximum open position. In the third operating position, the shift rod can in particular interact with the guide projection in such a way, in particular be in contact, that the blocking member is in the blocking position or can at least be converted into the blocking position.

In order to be able to use the wing arrangement flexibly, it can be advantageous if the wing can be attached to the right or left as required, ie the wing can be mounted pivotably on the left or right on the frame. It can then be advantageous if the guide device is designed in such a way that it can be mounted on the wing in two different positions that are opposite one another by 180°. As a result, one and the same guide device can be used for both right-hand and left-hand wing arrangements. This reduces the number of different components to be kept available and thus favors warehousing and the supply of spare parts.

Advantageously, the pin guide can also be designed in such a way that it can be mounted on the shift rod in two different positions or orientations that are opposite to one another by 180°. In other words, the pivot guide can be easily mounted in two opposite positions on the shift rod for use on right-hand or left-hand wing assemblies.

In a preferred embodiment, the opening-limiting device and the Self-locking device related to the direction of gravity between an upper crossbar of the frame (frame crossbar) and an upper crossbar of the wing (wing crossbar), between a lower crossbar of the wing and a lower crossbar of the frame or between a vertical wing spar on which the handle is located, and be arranged on a vertical frame spar (adjacent to it or assigned to this wing spar). As a result, the opening-limiting device and the self-locking device are largely protected against environmental influences such as rain, dust, dirt or the like.

Irrespective of this, the wing can optionally be additionally locked in the closed position via one or more locking points on the frame. One or more tumblers can be provided for this purpose. The handle can then be coupled to the at least one tumbler, in particular by means of the drive rod, in such a way that the at least one tumbler can be actuated by means of the handle. This contributes to particularly simple actuation of the wing arrangement, since the at least one tumbler and the self-locking device can be actuated using the same handle.

figure 1 Fig. 13 shows a wing assembly, designated by the reference numeral 10 as a whole. The casement assembly 10 includes a frame or fixed frame 12 and a casement 14 of a door or window. The wing 14 is, for example, by means of bands 16, pivotally mounted on the frame 12 and can be pivoted about a pivot axis 18 (pivot fitting).

The frame 12 has a lower frame rail 20, an upper frame rail 22 and two vertical frame rails 24,26. The wing frame or wing 14 has a lower wing cross member 28, an upper wing cross member 30 and two vertical wing spars 32,34. These delimit a wing element 36, e.g. a glazed wing panel 36.

A handle 38 is provided on the wing 14 by means of which tumblers (not shown) can be actuated to lock the wing 14 on the frame 12 . In addition, the casement arrangement 10 has an opening-limiting device 40, explained in detail below, with a self-locking device 42, which is exemplary located between the upper frame rail 22 and the upper wing rail 30 (in 1 only hinted at). The opening limiting device 40 and the self-locking device 42 can also be arranged at other points 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 points between the frame 12 and the leaf 14 is also conceivable.

As explained in detail below, the opening limiting device 40 only allows the sash 14 to be pivoted relative to the frame 12 up to a defined, partially open position (cf. Figure 8b ). The opening limiting device 40 comprises a pivot arm 44 arranged on the frame side (cf. 2 ), a switching rod 46 arranged on the wing side (cf. 3 ) and a guide device 48 arranged on the wing side (cf. 3 ). A limitation of an opening angle of the wing 14 is achieved in that the swivel 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 detail below).

The figure 2 shows the swivel arm 44 on its own. The pivot arm 44 is pivotally mounted at one end 54 to the upper frame rail 22 of the frame 12 (not shown) and has the pin 50 at the other end 56 discussed above. The pin 50 has a shank portion 58 and an opposite shank portion 58 in cross section (radially) enlarged head portion 60 on. At the end 54, the swivel arm 44 has a bearing block 62, by means of which the swivel arm 44 can be fastened to the frame 12, for example by screwing or clamping. 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. A detent 68 acted upon 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 swiveled, the detent 68 must first be overcome.

The guide device 48 and the switching rod 46 of the opening limiting device 40 are in 3 shown in detail. The shift rod 46 extends along a longitudinal direction 70. The shift rod 46 is, for example and preferably, guided displaceably on the wing 14 along the longitudinal direction 70, for example in a groove (not shown) formed on the upper wing cross member 30. How out 3 As can be seen, the shift rod 46 and the guide device 48 at least partially overlap one another along the longitudinal direction 70 .

A pin guide 72 is provided on the shift rod 46 and has lateral wall sections 74 , 76 which project beyond the shift rod 46 . The wall sections 74, 76 are spaced apart from one another in such a way as to receive the pin 50, in particular the head section 60 of the pin 50, between them. In the example, the pin guide 72 is separate from the Shift rod 46 formed. In the case of configurations that are not shown, the pin guide 72 can also be designed in one piece with the shift rod 46 .

In the example, the guide device 48 comprises a base body 78 and a guide plate 80 (cf. 3 ). The guide plate 80 is attached to the base body 78 by means of screws 82 , for example grub screws 82 . For this purpose, the guide plate 80 and the base body 78 have corresponding threaded holes 84 for receiving the screws 82 . The guide groove 52 already 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 .

In the example, the base body 78 is essentially U-shaped with two legs or walls 90, 92 running parallel to one another along the longitudinal direction 70, between which the pin 50 of the swivel arm 44 can be accommodated. The base body 78 is designed in such a way that the wall sections 74 , 76 of the pin guide 72 can be inserted between the legs 90 , 92 of the base body 78 .

The base body 78 is not slidably fixed to the upper wing cross member 30 of the wing 14 . Examples are lateral guide sections 94, 96 (cf. Figure 4a ) for coupling to a groove arranged on the upper wing spar 30 on the wing side. The guide sections 94, 96 are designed in such a way to engage behind lateral groove edges of the wing-side groove.

As already mentioned above, when the leaf 14 is in the partially open position, the pin 50 engages in the guide groove 52 and bears against the closed end 88 thereof (cf. Figure 8b ). As a result, further pivoting of the leaf 14 in the opening direction (away from the frame 12) is limited.

In order to be able to automatically lock the leaf 14 in this partially open position, the self-locking device 42 mentioned above is provided. The self-locking device 42 includes a swivel bolt 98 and a locking member 100, which are arranged, for example, between the base body 78 and the guide plate 80 (cf. 3 ).

The pivot bolt 98 is mounted on the guide device 48 so that it can pivot about a pivot axis 102 that is orthogonal to the switching rod 46, in particular vertical (cf. Figure 4a ). In the example, the base body 78 has a corresponding swivel lock receptacle 104 for receiving the swivel lock 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 (cf. also Figure 4a and 5 ). The further development of the pivot bolt 98 will be discussed later with respect to the figure 5 explained.

The locking member 100 is guided in a corresponding locking member receptacle 110 on the base body 78 of the guide device 48 and can be displaced along a displacement axis 114 parallel to a width direction 112 of the base body 78 (cf. Figure 4a ). The locking member receptacle 110 has a first stop 116 and a second stop 118 between which the locking member 110 is slidable. As explained in detail below, the blocking member 100 assumes a blocking position when it rests against the first stop 116 (cf. Figure 4a ), and a release position when it rests against the second stop 118 (cf. Figure 4b ).

The blocking member 100 is biased in the direction of the blocking position by means of a spring 120 . The spring 120 is accommodated, for example, in a corresponding spring receptacle 122 of the locking element 100 (cf. 6 ).

As in figure 6 shown, the locking member 100 has an engagement section 134, for example in the form of a hook section 134. The pivot bolt 98 has a corresponding locking member receiving section 136, in which the engaging section 134 of the locking member 100 can be received, in particular in a form-fitting manner (cf. figure 5 ). The swivel latch 98 also has a receiving section 138 for receiving the pin 50 . As explained in more detail below, the pivoting bolt 98 can be pivoted about the pivoting axis 102 by the interaction of the pin 50 with a first actuating section 140 of the pivoting bolt 98 or with a second actuating section 142 .

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

The guide contour 126 has a first guide section 128 and a second guide section 130 (cf. 3 ). If the guide projection 124 rests against the first guide section 128, the locking member 100 is in the release position. If the guide projection 124 is arranged at the level of the second guide section 130, the locking member 100 is either in the locking position or in the above-mentioned clamping position (explained in more detail below), depending on the position of the swivel bolt 98.

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

The handle 38 can be brought into different operating positions by turning it (e.g. 0°, 90°, 180° position). The handle 38 is coupled to a gear (not shown), which converts the rotational movement of the handle 38 into a translatory movement for the drive rod and thus into a displacement movement of the shift rod 46 along the longitudinal direction 70 .

The functioning of the opening-limiting device 40 and the self-locking device 42 is described below with reference to FIG Figures 7a to 11b explained.

Figure 7a shows the wing arrangement 10 in the closed position, ie the wing 14 is located within the frame 12. The handle 38 is in a first operating position (0° position or closed position). The (not shown) tumblers for locking the wing 14 on the frame 12 are locked. The wing 14 can thus not be pivoted relative to the frame 12.

How out Figure 7a , Views on the left, it can be seen that the switching rod 46 is in a first position corresponding to the first operating position of the handle 38 Shift position in which the locking member 100 rests with the guide projection 124 on the first guide portion 128 of the shift rod 46 and is thus shifted against the spring loading. The locking member 100 is in the in Figure 7a shown initial configuration with its engagement portion 134 on a clamping portion 144 of the pivot bolt 98 (see also figure 5 ) so that the pivot bolt 98 is acted upon by the spring loading of the locking member 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 member 100).

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

The pin 50 is located in Figure 7a still outside the guide device 48 in the pin guide 72, the lateral wall sections 74, 76 enclosing the head section 60 of the pin 50 laterally to the longitudinal direction 70 between them (closed position of the leaf 14).

At the in Figure 7b In the configuration shown, the wing 14 is inside the frame 12, but the handle 38 is rotated counterclockwise by 90° compared to the configuration shown in FIG. 5a (second operating position, 90° position). The (not shown) tumblers for locking the wing 14 on the frame 12 are unlocked. The wing 14 can thus be pivoted relative to the frame 12 .

How out Figure 7b , Views on the left, it can be seen that the switching rod 46 is in a second switching position corresponding to the second operating position of the handle 38, in which the switching rod 46 is opposite to the in Figure 7a position shown is displaced along the longitudinal direction 70 (in 7 "To the right"). Due to the shifting of the shift rod 46, the pivot guide 72 has become larger compared to that in Figure 7a configuration shown shifted a bit far from the guide device 48 out. The pin 50 is outside the guide means 48 and still in the pin guide 72.

In the second switching position of the switching rod 46, the locking member 100 is arranged at the level of the second guide section 130 of the switching rod 46, so that the pivoting member 100 could basically be transferred into the locked position (in Figure 7b a corresponding position of the blocking member in the blocking position is drawn in dashed lines). However, in the configuration shown, the locking member 100 is held in the clamped position by the pivot bolt 98 (pivot bolt 98 in contact with the holding section 148 of the guide device 48).

If the wing 14, starting from the in Figure 7b configuration shown, the pin 50 slides in the guide groove 52 towards the closed end 88 ("to the left" in the figures). How out Figure 8a As can be seen, when a predetermined position is reached, the pin 50 comes into contact with the first actuating section 140 of the swivel bolt 98 (cf. also figure 5 ), so that when the pin 50 is moved further in the direction of the closed end 88, the pivot bolt 98 is pivoted about the pivot axis 102 (in Figure 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. Figure 8b ), the pivot bolt 98 is in the closed position, in which the pin 50 is accommodated in the receiving section 138 of the pivot bolt (cf. Figure 8b ). As soon as the closed position of the pivoting bolt 98 is reached, the spring loading causes the locking member 100 to snap into the blocking position, in which the locking member 100 positively engages with its engagement section 134 in the locking member receiving section 136 of the pivoting bolt 98 (locking configuration of the self-locking device 42).

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 caught by the receiving portion 138 of the pivot bolt 98 and does not move in the direction of the free end 86 of the guide groove 52 (in Figure 8b "to the right") can be shifted. As such, the wing 14 is in the partially open position automatically locked by the self-locking device 42.

To start from the in Figure 8b To be able to close the wing 14 again in the configuration shown, that is to say to be able to pivot it from the partially open position into the closed position, the self-locking device 42 must be released. For this purpose, the locking member 100 must first be transferred from the locked position to the release position. In the case of the proposed wing arrangement 10, this occurs in that the handle 38 is moved from the second operating position (90° position) back into the first operating position (0° position) (cf. Figure 9a ).

As in Figure 9a , view on the left, the shift rod 46 is pushed back into the in Figure 7a shown first switching position (in the figures "to the left") process, in which the locking member 100 rests with the guide projection 124 on the first guide portion 128 of the shift rod 46. In contrast to the in Figure 7a However, in the configuration shown, the pivot bolt 98 is held in the closed position by the pin 50 and the locking member 100 is disengaged from the pivot bolt 98, so that a pivoting movement of the pivot bolt 98 about the pivot axis 102 is no longer blocked by the locking member 100.

If the wing 14 from the in Figure 9a shown configuration back towards the closed position transferred, the pin 50 slides from the closed end 88 of the guide groove 52 towards the free end 86 (in the figures "to the right"). In this case, the pin 50 acts with the second actuating section 142 of the swivel bolt 98 (cf. also figure 5 ) together and pivots pivot latch 98 to the open position (counterclockwise in the figures). As in Figure 9b , left view, shown, the locking member 100 then resumes the clamping position described above.

However, before the wing 14 can be completely closed, the handle 38 must - at least when tumblers are provided - be transferred once again into the 90° position (second operating position) in order, for example, to prevent the locking bolts of the tumblers from engaging in corresponding to enable locking recordings (cf. Figure 10a ). If the leaf 14 is in the closed position again (cf. Figure 10b ), the handle 38 can be transferred back into the first operating position (0° position) in order to lock the tumblers.

In Figure 11a is the wing 14 within the frame 12, but the handle 38 is pivoted into a third confirmation position (180 ° position or second open position). The (not shown) tumblers for locking the wing 14 on the frame 12 are unlocked. The wing 14 can thus be pivoted relative to the frame 12 . In this operating position (180 ° position), the opening limiting device 40 is inactive, so that the Wing 14 can be transferred from the closed position beyond the partially open position, e.g. to a fully open position.

How out Figure 11a 5b, the switching rod 46 is in a third switching position corresponding to the third operating position of the handle 38, in which 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. Starting from this configuration, the wing 14 is opened, the guide device 48 and the switching rod 46, which are arranged on the wing 14, from the pivot arm 44, which is on the frame 12 is arranged, pivoted away (cf. Figure 11b ). The wing 14 can thus be pivoted relative to the frame 12 like a conventional rotating wing.

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, the locking member 100 being prevented by the pivot bolt 98 from shifting into the locking position (clamping position).
