Description

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

A wing arrangement of the type mentioned is from EP 3 363 976 A1 famous. 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 wing is then locked in a partially open position relative to the frame. However, the rotation-limiting arrangement has a comparatively complex structure with a large number of individual elements that have to be manufactured precisely so that the rotation-limiting arrangement can function.

The invention is based on the object of providing a reliable rotary opening limitation on a wing arrangement with simple structural means. 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 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 has a switching rod, a guide plate and a scissor arm. The shift rod is slidably guided along a longitudinal direction on the wing (e.g. in a groove formed on the wing). The guide plate is fixed to the wing (not movable). The shift rail and the guide plate at least partially overlap each other along the longitudinal direction, with the shift rail is coupled by means of a connecting rod with a handle arranged on the wing side. The scissor arm is pivotally mounted to the frame at one end and has a pin at the other end which, at least in the partially open position of the sash, engages a closed-end guide groove formed in the guide plate, the pin being at the closed end in the partially open position End of the guide groove rests, whereby a (further) pivoting of the sash in the opening direction (away from the frame) is limited.

This creates a reliable opening limitation with a small number of components that are easy to manufacture and easy to assemble with simple design means. This contributes to a simple and inexpensive configuration of a wing arrangement.

The wing can have a groove for guiding (guide groove) 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 scissor arm can have a bearing block at one end, by means of which the scissor arm can be fastened to the frame (fixed frame), for example by clamping or screwing the bearing block to the frame. The arm or swivel arm can be swiveled relative to the bearing block. One or more stops can be provided on the bearing block be that limit a pivoting movement of the scissor arm in the closing direction (closed position). A detent, acted upon by a spring, for example, can be provided, which holds the scissor arm in the closed position. If the scissor arm is to be pivoted in the opening direction, the detent must first be overcome.

Advantageously, the shift rod can have a projection protruding in the direction of the guide plate, with a recess being formed on the guide plate at the closed end of the guide groove, into which the pin with a head section, preferably enlarged in cross section, can penetrate, the projection in a Switching position of the shift rod in the recess located in the head portion of the pin engages behind in such a way that the head portion is caught in the recess. In other words, the projection is then located on the recess in such a way that the head section of the pin cannot get out of the recess. Thus, by locking the pin relative to the guide plate, the wing is fixed or secured in the partially open position relative to the frame. The protrusion may have a detent surface for contacting the protrusion with the head portion. At one end or at both ends, which are aligned along the longitudinal direction of the shift rod, the projection can each have a ramp, on which the height of the projection increases from the respective end (towards the locking surface). By means of a ramp, the projection can introduce the head section of the pin into the recess or into this push in. The recess can be designed as a countersink (fixing countersink).

A pin guide can expediently be provided on the shift rod, which has lateral wall sections which project beyond the shift rod and are spaced apart in order to accommodate the pin, in particular the head section of the pin, between them. The pin guide guides the pin at least in one switch position or in two switch positions laterally to the longitudinal direction of the shift rod when the pin is outside of the guide groove of the guide plate. For example, when the wing is in the closed position, pin guiding can serve to guide the pin and insert it into the guide groove of the guide plate 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 the shift rod. In addition, this allows the use of different materials for the shift rod and pin guide. The shift rod and pin guide can be designed in such a way that they can be placed one inside the other for assembly, for example the shift rod can be placed in the pin guide. Retaining lugs and corresponding recesses for accommodating the retaining lugs can be provided for coupling the shift rod and pin guide, for example retaining lugs on the shift rod and recesses on the pin guide. The trunnion guide may have two lateral wall sections and a bottom section which connects the wall sections to one another. On the pin guide, in particular on the wall sections, laterally outwardly protruding guide lugs can be arranged for engagement with a groove formed on the wing. The wing-side groove can be constructed as described above.

Advantageously, the separately formed pin guide can be formed 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°. As a result, one and the same pivot guide 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 storage and the supply of spare parts. The trunnion guide becomes simple for use on right or left hinged wing assemblies mounted in two opposite positions on the shift rod.

The guide plate can expediently be designed in such a way that it can be mounted on the shift rod in two different positions that are opposite one another by 180°. As a result, one and the same guide plate 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.

As already indicated, the projection on the shift rod can have a ramp at each of its ends aligned along the longitudinal direction of the shift rod, with the height of the projection increasing from the end of the ramp in each case. As a result, the ramp can guide the head section of the pin into the recess from both sides. The projection together with the ramps (viewed from the side) can have a trapezoidal or an arcuate contour.

Within the scope of a preferred embodiment, the opening-limiting device can be attached, with respect to the direction of gravity, between an upper cross member of the frame (frame cross member) and an upper cross member of the wing (wing cross member), between a lower cross member of the sash and a lower cross member of the frame or between a vertical wing member which the Handle is located, and a vertical frame member (adjacent to or assigned to this wing member) can be arranged. As a result, the opening-limiting device is largely protected against environmental influences such as rain, dust, dirt or the like.

Irrespective of this, two opening-limiting devices can optionally be provided, which are arranged at different points between the sash and the frame. For example, a first opening limiting device can be arranged between an upper crossbar of the frame and an upper crossbar of the wing and a second opening limiting device can be arranged between a lower crossbar of the wing and a lower crossbar of the frame. As a result, higher loads, for example higher wind loads, can be absorbed.

In concrete terms, the shift rod and the handle can be coupled to one another (e.g. by means of connecting rods) in such a way that the shift rod can be brought into different switch positions depending on the actuation 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 transmission which the Converts rotary movement of the handle into a translational movement, for example. For the connecting rods.

Expediently, when the handle is in a first operating position (0° position or closed position), the switching rod can be in a first switching position in which the projection on the switching rod engages behind the recess on the guide plate, with when the wing is in the closed position, the head portion is outside the guide plate, and/or wherein when the wing is in the partially open position the head portion is located in the recess. Thus, the operating position of the handle in the closed position and in the partially open position for fixing the door leaf is identical. This facilitates the operation of the wing assembly.

Advantageously, when the handle is in a second operating position (90° position or first open position), the switching rod can be in a second switching position in which the projection on the switching rod is displaced away from the recess (i.e. the recess is not more grips behind), so that the sash can be pivoted between the closed position and the partially open position. Thus, the head portion of the pin can be displaced in and out of the recess, allowing (limited) pivoting of the wing.

As part of a preferred embodiment, when the handle is in a third operating position (180° position or second open position), the switching rod can be in a third switching position in which the head section is outside the guide plate and outside the pin guide, so that the wing can be pivoted between the closed position and an open position (position in which the wing is more open than in the partially open position) as in a conventional rotary wing.

Advantageously, several locking devices can be provided to lock the sash in the closed position on the frame, the handle being coupled to the locking devices, in particular by means of the connecting rod, so that the locking devices can be actuated by means of the handle. This contributes to a particularly simple actuation of the wing arrangement, since the locking devices and the opening-limiting device of the wing, in particular their determination in the partially open position of the wing, can be actuated using the same handle.

Specifically, the guide groove can extend along a central longitudinal direction of the guide plate and be delimited laterally by walls, the pin guide being designed in such a way that the pin guide can be pushed into the guide groove between the walls. This favors a compact and flexible configuration of the opening-limiting device. The guide plate can have, in particular on the walls laterally delimiting the guide channel, guide sections for coupling to a groove arranged on the wing side.

Advantageously, the guide plate can have groove edge sections projecting into the clear cross section of the guide groove, on the underside of which the recess is formed, the underside having a surface section that is offset in height relative to the recess or a surface section that is aligned with the recess. A surface section that is offset in height contributes to a structurally comparatively simple design of the guide plate, with material weaknesses on the groove edge sections being largely avoided. An aligned surface section favors an arrangement of the guide plate in two orientations, since the head section of the pin can also be guided out of the guide groove when the projection is in the area of the guide groove. A retaining section can be arranged on the side of the recess facing away from the closed end, which delimits the recess on the side facing away from the closed end.

figure 1 Fig. 13 shows a wing assembly, designated by the reference numeral 10 as a whole. The casement arrangement 10 has a frame or fixed frame 12 and a casement 14 of a door or a window, which is pivotably mounted on the frame 12 . The wing 14 is pivotally mounted on the frame 12 by means of bands 16 and can be pivoted about a pivot axis 18 (pivot fitting). A rotary fitting is shown in the example, but the use of a tilt and turn fitting is also conceivable.

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 locking devices (not shown) for locking the wing 14 on the frame 12 can be actuated. In addition, the wing arrangement 10 has an opening limiting device 40 (in Fig.1 only hinted at). The opening limiting device 40 is in the example between the upper frame cross member 22 and the upper wing cross member 30 are arranged. As explained above, the opening restricting device 40 can also be arranged at other locations between the frame 12 and the sash 14 . The use of two opening-limiting devices 40 arranged at different points between the frame 12 and the leaf 14 is also conceivable.

As explained further 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. Figures 8a to 9b ).

figure 2 shows the opening-limiting device 40 on its own. The opening limiting device 40 has a switching rod 42, a guide plate 44 and a scissor arm 46. Connecting rods 50, 52 are coupled (only indicated) to coupling elements 48 of the shift rod 42.

The shift rod 42 and the drive rods 50, 52 are guided on the wing 14 along a longitudinal direction 54 for displacement, specifically in a groove formed on the upper frame cross member 30 of the wing 14 (not shown). The guide plate 44 is non-slidably fixed (not shown) to the upper frame rail 30 of the wing 14 . The shift rod 42 and the guide plate 44 at least partially overlap one another along the longitudinal direction 54 . The switching rod 42 is coupled to the handle 38 arranged on the wing side by means of at least one of the drive rods 50, 52, so that the switching rod 42 can be actuated by means of the handle 38. The scissors arm 46 is pivotally mounted at one end 56 to the upper frame rail of the frame 12 (not shown) and has a pin 60 at the other end 58 (see Figs. figure 4 ). At least when the leaf 14 is in the partially open position, the pin 60 engages in a guide groove 62 which is formed in the guide plate 44 and is closed at one end, the pin 60 bearing against the closed end 64 of the guide groove 62 in the partially open position (cf. Figure 8b , 9b ). As a result, further pivoting of the leaf 14 in the opening direction (away from the frame 12) is limited. The shift rod 42, the guide plate 44 and the scissor arm 46 are explained in more detail below.

the Figures 3a to 3c show the guide plate 44 on its own. As discussed, the guide plate 44 has a guide groove 62 with a closed end 64 . The guide groove 62 is bounded laterally by walls 66, 68. On the walls 66 , 68 , groove edge sections 70 , 72 are provided which protrude into the clear cross section of the guide groove 62 and which are connected to one another at one end of the guide groove 62 and thus form the closed end 64 of the guide groove 62 .

The groove cross section of the guide groove 62 is tapered between the groove edge sections 70,72. Thus, by means of the groove edge portions 70, 72, a shank portion of a pin be led. A head section of the pin 60 can be guided by means of the walls 66, 68 (non-tapered groove cross section).

A recess 74 is formed at the closed end 64 of the guide groove 62, into which the pin 60 can penetrate with a head portion, as explained further below. The recess 74 is formed on an underside 75 of the groove edge sections 70, 72. The recess 74 is designed as a preferably conical countersink. The underside 75 has a surface section 77 that is offset in height relative to the recess 74 .

On the guide plate 44, lateral guide sections 76, 78 are formed on the walls 66, 68 for coupling to a groove arranged on the upper wing spar 30 on the wing side. The guide sections 76, 78 are designed in such a way that they engage behind lateral groove edges of the groove on the wing side. At least two, in the example four, threaded bores 80 are formed on the guide plate 44 in order to fasten the guide plate 44 to the wing-side groove. In the example, the threaded bores 80 can accommodate screws, for example grub screws, in order to brace the guide plate 44 relative to the groove on the wing side.

figure 4 shows the scissor arm 46 on its own. The scissor arm 46 has the pin 60 at the end 58 . The spigot 60 has a shank portion 82 and, in cross-section (radially) opposite the shank portion 82, expanded head portion 84 on. At the end 56, the scissor arm 46 has a bearing block 86, by means of which the scissor arm 46 can be fastened to the frame 12, for example by clamping. The arm 87 can be pivoted relative to the bearing block 86 . A stop 88 is provided on the bearing block 86, which limits a pivoting movement of the arm 87 relative to the bearing block 86 in the closing direction. A detent 92 acted upon by a spring 90 is provided, which holds the arm 87 in the closed position relative to the bearing block 86 . If the arm 87 is to be pivoted, the detent must first be overcome.

figure 5 shows the shift rod 42 on its own. The switching rod 42 has at each of its ends a coupling element 48 for coupling connecting rods. Furthermore, in the example, the push rod 42 has laterally protruding guide sections 94 for guidance in a groove arranged on the wing side on the upper wing spar 30 .

The switching rod 42 has a projection 96 which projects upwards, ie in the direction of the guide plate 44 . The projection 96 serves to engage behind the head section of the pin 60 at the closed end 64 of the guide groove 62 so that it is caught in the recess 74 . In the example, the projection 96 has a detent surface 98 with which the projection 96 comes into contact with the head portion of the pin 60 . At one end aligned along the longitudinal direction of the shift rod 42, the projection 96 has a ramp 100 at which the height of the projection 96 from the end, ie towards the detent surface 98 increases. As a result, the projection 96 can insert the head section 84 of the pin 60 into the recess 74 of the guide plate 44 by means of the ramp 100 .

A pin guide 102 is provided on the shift rod 42, which has lateral wall sections 104, 106 which project beyond the shift rod 42 and are spaced apart in order to receive the pin 60, in particular the head section 84 of the pin 60, between them. In the example, the pin guide 102 is formed in one piece with the shift rod 42, although a separate configuration is also conceivable.

The switching rod 42 and the handle 38 are coupled to one another, in particular via connecting rods, in such a way that the switching rod 42 can be brought into different switching positions depending on the actuation positions of the handle 38 . The handle 38 can be brought into different operating positions by turning it. 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 connecting rod.

The operation of the wing assembly 10 is based on the Figures 6a to 12b explained. An opening of the wing 14 to the partially open position is in the Figures 6a to 9b shown.

Figure 6a 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 locking devices (not shown) for locking the leaf 14 to the frame 12 are locked. The wing 14 can thus not be pivoted relative to the frame 12.

Figure 6b shows the opening-limiting device 40 in the associated position, with the sash cross member 22 and the frame cross member 30 also being indicated. Corresponding to the first actuation position of the handle 38 , the switching rod 42 is in a first switching position, in which the projection 96 is located below the recess 74 . The spigot 60 is located outside of the guide plate 44 in the spigot guide 102, the lateral wall sections 104, 106 (cf. Fig.5 ) enclose the head portion 84 of the pin 60 laterally to the longitudinal direction 54 between them.

In Figure 7a is the wing 14 within the frame 12, but the handle 38 is in a second confirmation position (90 ° position or first open position). The (not shown) locking devices for locking the wing 14 to the frame 12 are unlocked. The wing 14 can thus be pivoted relative to the frame 12 .

Figure 7b shows the opening-limiting device 40 in the associated position. Corresponding to the second operating position of the handle 38, the switching rod 42 is in a second switching position in which the projection 96 is displaced away from the recess 74. By shifting the shift rod 42, the pin guide 102 was shifted a little way into the guide groove 62. The pin 60 is located outside of the guide plate 44 in the pin guide 102, with the lateral wall sections 104, 106 enclosing the head section 84 of the pin 60 laterally to the longitudinal direction 54 between them.

In Figure 8a the wing 14 has been pivoted relative to the frame 12 to the partially open position. The handle 38 is in the second confirmation position.

Figure 8b shows the opening-limiting device 40 in the associated position. The shift rod 42 is in the second shift position, in which the projection 96 is displaced away from the recess 74 . By pivoting the wing 14, the arm 87 of the scissor arm 46 was also pivoted, the pin 60 being displaced into the guide plate 44 and lying against the closed end 64 of the guide groove 62. The head portion 84 of the pin is directly below the recess 74.

Figure 9a shows the wing arrangement Fig.1 in the partially open position, the handle 38 being pivoted back into the first operating position (0° position or closed position).

Figure 9b shows the opening-limiting device 40 in the associated position. The shift rod 42 is in the first shift position, in which the projection 96 is located below the recess 74 . As a result, the head portion 84 of the pin 60 is trapped in the recess 74 and cannot be guided out of it. Thus, the leaf 14 is locked in the partially open position relative to the frame 12 via the scissor arm 46 .

In the Figures 10a to 12b a full opening of the wing assembly 10 is illustrated.

Figure 10a shows the wing arrangement 10 in the closed position analogously to FIG Figure 6a . Figure 10b shows the opening-limiting device 40 in the associated position analogously to FIG Figure 6b . To avoid repetition, reference is made to the explanations given there.

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) locking devices for locking the wing 14 to the frame 12 are unlocked. The wing 14 can thus be pivoted relative to the frame 12 .

Figure 11b shows the opening-limiting device 40 in the associated position. The shift rod 42 is located corresponding to the third operating position of the handle 38 in a third switching position in which the head section 84 of the pin 60 is located outside of the guide plate 44 and outside of the pin guide 102, which has been displaced into the guide plate 44 by displacement of the shift rod 42. Thus, the head portion 84 or the pin 60 is disengaged from the guide plate 44 and the pin guide 102.

Figure 12a shows the wing arrangement 10 in the open position, ie the wing 14 has been pivoted relative to the frame 12 into a position further than the only partially open position, in the example the wing 14 has been pivoted relative to the frame 12 by an angle of 90°.

Figure 12b shows the opening-limiting device 40 in the associated position. By pivoting the wing 14, the guide plate 44 and the shift rod 42, which are arranged on the wing 14, from the scissor arm 46, which is arranged on the frame 12, pivoted away. The wing 14 can thus be pivoted relative to the frame 12 like a conventional rotating wing.

the Figures 13a to 16 show a possible embodiment of shift rod 42, guide plate 44 and pin guide 102.

The shift rod 42 largely corresponds to the shift rod 42 described above, so that to avoid Repetitions are referred to the statements there.

Deviating from this, the projection 96 has a ramp 100 on both ends aligned along the longitudinal direction of the shift rod 42 (cf. Figure 13c and Fig.15 ). Thus, the switching rod 42 can be used with wing assemblies 10 hinged on the right and on the left. The projection 96 may have an arcuate contour.

In the present case, the pin guide 102 is designed separately from the shift rod 42 and can be mounted on the shift rod 42 . The pin guide 102 has lateral wall sections 104, 106 and a connecting bottom section 108 (cf. Figure 14c and Fig.15 ). On each of the wall sections 104, 106 there is a laterally outwardly projecting guide lug 110, 112 for engagement with a groove arranged on the wing side (not shown).

Shift rod 42 and pin guide 102 are designed in the example in such a way that they can be placed one inside the other for assembly, so the shift rod 42 can be inserted into the pin guide 102 . To couple shift rod 42 and pin guide 102, two retaining lugs 114 are formed on shift rod 42 and at least one recess 116 is formed on the pin guide to accommodate one of the retaining lugs 114 (cf. Fig.15 ). The pin guide 102 is designed in such a way that it can be mounted on the shift rod 42 in two positions or orientations that are opposite to one another by 180°. The same applies to the guide plate 44.

In the Figures 13a to 13c For example, guide plate 44 and pin guide 102 are mounted to shift rail 42 in a first orientation. The switching rod 42 is in different switching positions, namely a first switching position ( Figure 13a ), a second switching position ( Figure 13b ) and a third switching position ( Figure 13c ).

In the first switching position ( Figure 13a ) is the projection 96 below the recess 74 at the closed end 64 of the guide groove 62. In the second switch position ( Figure 13b ) and the third switching position ( Figure 13c ) the projection 96 is displaced out of the guide groove 62 of the guide plate 44, starting from the end of the guide plate 44 where the closed end 64 is located.

In the Figures 14a to 14c For example, guide plate 44 and pin guide 102 are mounted on shift rod 42 in a second orientation that is rotated 180° from the first orientation. The switching rod 42 is in different switching positions, namely a first switching position ( Figure 14a ), a second switching position ( Figure 14b ) and a third switching position ( Figure 14c ).

In the first switching position ( Figure 14a ) is the projection 96 below the recess 74 at the closed end 64 of the guide groove 62. In the second switch position ( Figure 14b ) and the third switching position ( Figure 14c ) the projection 96 is displaced a little along the guide plate 44, with the projection 96 being in the second switching position ( Figure 14b ) approximately in the middle of the guide groove 62 and in the third switching position ( Figure 14c ) is located approximately at the open end of the guide groove 62.

This means that the head section 84 of the pin 60 has to pass the projection 96 in the second switching position of the switching rod 42 in order to be guided along the guide groove 62 into the recess 74 or out of the recess 74 .

Irrespective of this, the recess 74, which is preferably designed as a countersink, and the slope provided on the countersink, the head section 84 can be automatically released from the (caught) position in the recess 74 when the leaf 14 is closed.

The underside 75, on which the recess 74 is formed, therefore has a surface section 118 which is flush with the recess 74 in height relative to the recess 74 (cf. Fig.16 ). The recess 74 can be on the side facing away from the closed end of the guide groove 62 have a retaining portion 120 which delimits the recess 74 .

Thus, the pin 60 can be moved with its head section 84 starting from the recess (pin 60 ′) downwards towards the shift rod 42 and guided past the retaining section 120 . Thereafter, the pin is moved upwards away from the shift rod 42 in order to pass the projection 96 (pin 60"). The pin 60 can then be moved again towards the shift rod 42 and guided out of the guide plate 44 (pin 60'''). .
