Description

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

[0002] A wing arrangement of the type mentioned above is known from the prior art, e.g., from EP 3 985 216 A1. The wing arrangement described therein has an opening limiting device by means of which, depending on requirements and via a handle, the wing can be fully opened or the opening of the wing can be reliably limited to a partially open position. For opening limiting, a pin engages with a guide groove, whereby a head section of the pin can penetrate a corresponding recess and is engaged behind it by a projection and thus secured. However, practical experience has shown that the locking of the scissor arm on the guide plate is comparatively rigid. This type of locking also places high demands on the dimensional accuracy of the individual components so that they function together correctly.Depending on the design and size of the wing arrangement, the rigid locking mechanism may mean that the opening limiting device can only be installed between the upper wing and upper frame cross member or the lower wing and lower frame cross member, relative to the direction of gravity.

[0003] The invention is based on the objective of enabling a flexibly applicable opening limitation in wing arrangements using structurally simple means.

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

[0005] An opening limiting device is provided which allows the sash to pivot relative to the frame only up to a defined, partially open position (the pivoting process of the sash is limited from the closed position in the opening direction).

[0006] The opening limiter comprises a switching rod, a notched plate, and a scissor arm. The switching rod is guided so that it can slide along the sash in a longitudinal direction (e.g., in a groove formed in the sash). The notched plate is fixed to the sash (and cannot slide). The switching rod and the notched plate overlap each other at least partially along the longitudinal direction, with the switching rod being coupled to a handle located on the sash side by means of a drive rod.

[0007] The scissor arm is pivotally mounted to the frame at one end and has a pin at the other end. At least when the sash is partially open, this pin engages in a guide groove, closed at one end, defined jointly by the actuating rod and the notched plate. In the partially open position, the pin rests against a recess (pin receptacle) formed in the notched plate at the closed end of the guide groove. This limits further pivoting of the sash in the opening direction (away from the frame).

[0008] In this way, a reliable opening limiter is created using simple design elements with a small number of components that are easy to manufacture and assemble. This contributes to a simple and cost-effective design of the wing assembly. Furthermore, the recess formed in the notched plate facilitates the insertion of the pivot with a certain amount of play, so that the pivot and, if applicable, the scissor arm can be moved or pivoted orthogonally to the central longitudinal axis of the pivot. This simplifies assembly and allows for more flexible use of the opening limiter.

[0009] The sash may have a groove for guiding the switching rod (sash groove). The groove may have lateral groove edges that project into the clear cross-section of the sash-side groove and engage behind the switching rod (e.g., one or more laterally projecting guide sections) and / or the notched plate (tab or laterally projecting guide sections) when the switching rod or the notched plate is / are arranged in the groove.

[0010] The scissor arm can have a bearing block at one end, which allows it to be attached to the frame (fixed frame), for example, by clamping or screwing the bearing block to the frame. The arm, or pivoting arm, can pivot relative to the bearing block. One or more stops can be provided on the bearing block to limit the pivoting movement of the scissor arm in the closing direction (closed position). A detent, for example, spring-loaded, can be provided to hold the scissor arm in the closed position. If the scissor arm is to be pivoted in the opening direction, the detent may first need to be overcome.

[0011] The guide groove formed in the shift rod is open towards the frame (fixed frame) or along the central longitudinal axis of the pin, so that the pin of the frame-mounted scissor arm can engage in the guide groove. The guide groove is bounded laterally by the shift rod and the notched plate. As already indicated above, the shift rod and the notched plate jointly define the guide groove. In other words, the guide groove is not defined by a single component alone.

[0012] According to the invention, the switching rod has a locking section extending towards the notched plate. The locking section is designed such that, in a switching position of the switching rod, it can close or does close the recess, so that the pin is trapped in the recess. In other words, the pin is then located in the recess, and the locking section prevents the pin from being removed from the recess. Thus, by locking the pin relative to the notched plate, the wing is fixed or secured in the partially open position relative to the frame.

[0013] In a further aspect of the invention, the guide groove is formed on the switching rod, wherein the guide groove (transverse to the longitudinal direction) is bounded on one side by a switching rod wall section and on an opposite second side by the notched plate. This contributes to a design of the opening limiting device with comparatively few components. The switching rod wall section is, in particular, formed integrally with the switching rod. Specifically, the switching rod can have a groove section through which the pin can pass when pivoting the wing between a closed position and the partially open position. The locking section can optionally be connected to the groove section via an intermediate section, preferably concavely curved.At the end of the locking section facing away from the groove section, the switching rod may have a connecting section via which the switching rod can be connected to a drive rod arranged on the wing side.

[0014] Specifically, the switching rod wall section and the locking section can be connected to each other by means of an intermediate section, preferably with a concave rounded edge towards the guide groove, as already indicated. This avoids notches or corner areas prone to dirt accumulation. Furthermore, the intermediate section facilitates the deflection of the pin into the recess when the sash is pivoted into the partially open position. The intermediate section thus makes it easier to insert the pin into the recess.

[0015] Advantageously, a wall section can be formed on the switching rod opposite the switching rod wall section, wherein the wall section and the switching rod wall section are spaced apart from each other to accommodate the pin (and optionally any head section of the pin) between them. The wall section guides the pin laterally to the longitudinal direction of the switching rod, at least in one switching position, or in two switching positions, together with the switching rod wall section, when the pin is not (yet) located between the switching rod or the switching rod wall section and the (shorter along the longitudinal direction) notched plate (pin outside the gap between the notched plate and the switching rod wall section). Thus, when the wing is in the closed position, the wall section can guide the pin (one-sidedly) and insert the pin into the gap.The groove section between the switching rod wall section and the notched plate serves as a guide when the sash is opened from the closed position and the pin moves towards the closed end of the guide groove. The wall section is preferably formed integrally with the switching rod.

[0016] In a preferred embodiment, the recess of the notched plate and the locking section of the switching rod can be aligned such that the pin and / or the scissor arm can be pivoted relative to the bottom of the guide groove by an angle of 10°–20°, preferably 13°–17°, and more preferably 15°. This facilitates flexible use of the opening limiter, allowing it to be mounted at different locations on the sash, for example, also on the hinge side (where the handle is located on the sash side). The specified angle ranges refer to an angle between a first plane, whose normal vector is the central longitudinal axis of the pin, and a second plane in which the bottom of the guide groove lies.

[0017] Advantageously, the switching rod can be slidably guided along its longitudinal direction in a wing groove formed in the wing, wherein the notched plate has a tab extending transversely, and in particular orthogonally, to the longitudinal direction through the wing groove, so that movement of the notched plate transversely, and in particular orthogonally, to the longitudinal direction of the wing groove is limited, and in particular prevented. This secures the arrangement of the notched plate relative to the wing groove or relative to the switching rod, thus ensuring its intended function. Optionally, the notched plate can additionally be secured to the wing frame by means of screws, e.g., set screws. The tab can extend (orthogonally to the longitudinal direction) over the entire width of the wing groove or the clear cross-section of the wing groove.Preferably, the tab can extend below the shift rod through the wing groove, and is thus arranged between the bottom of the wing groove and the shift rod. The tab can be wider (perpendicular to the longitudinal direction) than the shift rod. With respect to the longitudinal direction, the shift rod can rest against the edge of the wing groove on one side for guidance and against the groove plate on the opposite side.

[0018] Advantageously, the switching rod can be designed symmetrically with respect to a plane that intersects the switching rod and whose normal vector extends along the longitudinal direction of the guide groove. In other words, the switching rod can be designed as a mirror image (with respect to the plane). This allows the switching rod to be used on both the left and right sides, reducing the number of components for the opening limiting device. Thus, separate left- and right-hand versions of the switching rod are not required. With a symmetrical design, the switching rod can therefore have two connecting sections for coupling drive rods, an extended (symmetrical with respect to the plane) groove section, two locking sections, and / or two intermediate sections.

[0019] Alternatively, the switching rod and / or the notched plate can each be provided or designed in a left-hand version (left part) and a separate right-hand version (right part). This allows these parts to be specifically optimized for use as either a right-hand or left-hand part without having to consider the constraints of a symmetrical (mirror-image) design. Depending on the configuration of the wing (left / right), the switching rod must be used in either a right-hand or left-hand version. The left-hand or right-hand version of the switching rod can then have two connecting sections for coupling drive rods, a groove section, a locking section, and / or an intermediate section.

[0020] In principle, the opening limiting device can be arranged or installed, relative to the direction of gravity, between an upper sash cross member and an upper frame cross member, or between a lower sash cross member and a lower frame cross member. Preferably, the opening limiting device can be arranged or installed, relative to the direction of gravity, between a vertical sash cross member, on which the handle is located, and a corresponding vertical frame member (arrangement on the opposite side of the hinge). Such an arrangement is particularly advantageous with a pivotable pivot or scissor arm, as described above.

[0021] Specifically, the shift rod and the handle (e.g., via connecting rods) can be coupled in such a way that the shift rod can be moved into different switching positions depending on the operating positions of the handle. Thus, defined operating positions of the handle (e.g., closed position (e.g., 0° position), first opening position (e.g., 90° position), and second opening position (e.g., 180° position)) can in turn correspond to defined switching positions of the shift rod (e.g., a first, second, and third switching position). The handle can be coupled to a gearbox that converts the rotary motion of the handle into a translational motion, e.g., for the connecting rods.

[0022] Advantageously, when the handle is in a first operating position (0° position), the switching rod can be in a first switching position in which the locking section closes the recess, whereby, when the sash is in the closed position, the pin is located outside the recess, and / or, when the sash is in the partially open position, the pin is located in the recess. Thus, the operating position of the handle for locking the sash is identical in both the closed and partially open positions. This facilitates the operation of the sash assembly.

[0023] Advantageously, when the handle is in a second operating position (90° position or first opening position), the switching rod can be in a second switching position in which the locking section is moved away from the recess (i.e., it no longer closes the recess), so that the sash can pivot relative to the frame between the closed and partially open positions. Thus, the pivot can be moved into and out of the recess, allowing for (limited) pivoting of the sash.

[0024] In a preferred embodiment, when the handle is in a third operating position (180° position or second opening position), the switching rod can be in a third switching position in which the pin is located outside the recess and outside the gap or groove section between the switching rod wall section and the wall section, so that the sash can be pivoted between the closed position and an open position (position in which the sash is open further than in the partially open position) as with a conventional hinged sash.

[0026] Figure 1Figure 10 shows a sash arrangement, which is designated as a whole by the reference numeral 10. The sash arrangement 10 comprises a frame or fixed frame 12 and a sash 14 of a door or window, which is pivotally mounted on the frame 12. The sash 14 is pivotally mounted on the frame 12 by means of hinges 16 and can be pivoted about a pivot axis 18 (turn fitting). In the example, a turn fitting is shown, but the use of a tilt-and-turn fitting is also conceivable.

[0027] 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.

[0028] A handle 38 is provided on the sash 14, by means of which locking devices (not shown) can be actuated to lock the sash 14 to the frame 12. In addition, the sash assembly 10 has an opening limiting device 40 (in Figure 1 (only indicated). In this example, the opening limiting device 40 is arranged between the vertical frame member 24 and the vertical sash member 32, on which the handle 38 is located (opposite the hinge side). Alternatively, the opening limiting device 40 could be arranged between the upper frame cross member 22 and the upper sash cross member 30 or between the lower sash cross member 28 and the lower frame cross member 20 (not shown).

[0029] As explained 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). Figures 6 to 9 ).

[0030] Figure 2Figure 1 shows the opening limiting device 40 in isolation. The opening limiting device 40 has a switching rod 42, a notched plate 44, and a scissor arm 46. Connecting rods 50 and 52 are coupled to coupling elements 48 of the switching rod 42 (only indicated).

[0031] The switching rod 42 and the connecting rods 50, 52 are slidably guided on the wing 14 along a longitudinal direction 54, namely in a wing groove 55 formed on the vertical wing spar 32 of the wing 14 (cf. Figure 5a and 5bThe notched plate 44 is fixed to the vertical wing member 32 of the wing 14 in a non-slidable manner, e.g., screwed in place (not shown). The actuating rod 42 and the notched plate 44 overlap each other at least partially along the longitudinal direction 54. The actuating rod 42 is coupled to the handle 38 located on the wing side by means of at least one of the drive rods 50, 52, so that the actuating rod 42 can be actuated by means of the handle 38. The scissor arm 46 is pivotably mounted at one end 56 on the vertical frame member 24 of the frame 12 (not shown) and has a pin 60 at the other end 58 (see figure). Figure 5a and 5b ). The pin 60 engages, at least in the partially open position of the wing 14, in a guide groove 62 defined jointly by the switching rod 42 and the notched plate 44, which is closed at one end (cf. Figure 2), wherein the pin 60 in the partially open position is arranged or rests against the closed end 64 of the guide groove 62 in a recess 65 formed in the notched plate 44 (see e.g. Figure 4a This limits further pivoting of the wing 14 in the opening direction (away from the frame 12). The switching rod 42, the notched plate 44, and the scissor arm 46 are explained in more detail below.

[0032] The scissor arm 46 has a pin 60 at its end 58. The pin 60 has a shaft section 66 and a head section 68 which is radially wider in cross-section than the shaft section 66 (see figure). Figure 5a and 5bAt end 56, the scissor arm has a bearing block 70, by means of which the scissor arm 46 can be attached to the frame 12, e.g., by clamping. The arm 71 is pivotable relative to the bearing block 70. A stop 72 is provided on the bearing block 70, which limits the pivoting movement of the arm 71 relative to the bearing block 70 in the closing direction. A spring-loaded detent is also provided, which holds the arm 71 in the closed position relative to the bearing block 70 (not shown). If the arm 71 is to be pivoted, the detent must first be overcome.

[0033] The Figures 3a and 3b Figure 42 shows the switching rod 42 and the notched plate 44 in isolation. The switching rod 42 has a locking section 74 extending towards the notched plate 44. In a switching position of the switching rod 42 (first switching position), this section can close the recess 65, so that the pin 60 is caught in the recess 65 (see Figure 4). Figure 2 , 4a and 9).

[0034] In the example, the guide groove 62 is formed on the shift rod 42, wherein the guide groove 62 is limited on one side by a shift rod wall section 75 and on an opposite second side is partially limited by the notched plate 44 (see Figure 2 and 9 The switching rod wall section 75 is formed integrally with the switching rod 42. In the example, the switching rod 42 has a groove section 76, which the pin 60 can pass through, or does pass through, when the wing 14 pivots between a closed position and the partially open position (see figure). Figure 4b ).

[0035] The switching rod wall section 75 and the locking section 74 are connected by means of an intermediate section 77 which is concavely rounded towards the guide groove 62. The intermediate section 77 facilitates the insertion of the pin 60 into the recess 65 (see figure). Figure 4b ).

[0036] On the switching rod 42, a wall section 78 is formed opposite the switching rod wall section 75, wherein the wall section 78 and the switching rod wall section 75 are spaced apart from each other to accommodate the pin 60 between them. The wall section 78, together with the switching rod wall section 75, can then guide the pin 60 laterally to the longitudinal direction 54 of the switching rod 42 if the pin 60 is not (yet) located between the switching rod 42 or the switching rod wall section 75 and the notched plate 44. In the example, the wall section 78 is formed integrally with the switching rod 42.

[0037] The recess 65 of the notched plate 44 and the locking section 74 of the switching rod 42 are aligned such that the pin 60 and / or the scissor arm 46 can be pivoted relative to the groove base of the guide groove 62 by an angle α, in the example by an angle α of 15° (see figure). Fig.5b). The specified angle refers to an angle between a first plane E1, whose normal vector is the central longitudinal axis of the pin 60, and a second plane E2, in which the groove base of the guide groove 62 lies.

[0038] As already explained, the switching rod 42 is slidably guided along the longitudinal direction 54 in a wing groove 55 formed on the wing 14. The notched plate 44 has a tab 79 that extends transversely, in this example orthogonally, to the longitudinal direction 54 of the wing groove 55, so that movement transversely, in this example orthogonally, to the longitudinal direction 54 of the wing groove is limited, in this example prevented (see figure). Figure 5a and 5b ). In the example, the tab 79 extends over the entire width of the wing groove 55.

[0039] In this case, the tab 79 extends below the shift rod 42 through the wing groove 55, and is thus arranged between a groove base of the wing groove 55 and the shift rod 42. The tab 79 is wider (orthogonal to the longitudinal direction 54) than the shift rod 42. With respect to the longitudinal direction 54, the shift rod 42 rests on one side against the edge of the wing groove 55 for guidance and on the opposite side against the groove plate 44. Edge-side engagement sections 55', 55'' of the wing groove 55 can engage the shift rod 42 and the groove plate 44, respectively, in sections.

[0040] The switching rod 42 is symmetrical with respect to a plane SE1 that intersects the switching rod 42 and whose normal vector extends along the longitudinal direction 54 of the guide groove 62. In other words, the switching rod is mirror-symmetrical with respect to the plane SE1. In the example, the notched plate 44 is also mirror-symmetrical with respect to a plane SE2 that intersects the notched plate 44 at the recess 65.

[0041] As already indicated, the switching rod 42 can be moved into different switching positions depending on the actuation positions of the handle 38. The function of the wing assembly 10 is explained below with reference to the Figures 6 to 12 explained. Opening the wing 14 to the partially open position is described in the Figures 6 to 9 shown.

[0042] Figure 6The figure shows the sash assembly 10 in the closed position, i.e., the sash 14 is located within the frame 12. The handle 38 is in a first operating position (0° position or closed position). The locking devices (not shown) for securing the sash 14 to the frame 12 are locked. The sash 14 therefore cannot be pivoted relative to the frame 12.

[0043] Figure 6 The opening limiting device 40 is also shown in its corresponding position. The switching rod 42 is in a first switching position corresponding to the first actuation position of the handle 38, in which the locking section 74 closes the recess 65 of the notched plate 44. The pin 60 is located in the guide groove 62 between the switching rod wall section 75 and the wall section 78 (thus still outside the section of the guide groove 62 or the space between the switching rod wall section 75 and the notched plate 44).

[0044] In Figure 7 The sash 14 is located within the frame 12, however, the handle 38 is in a second operating position (90° position or first opening position). The locking devices (not shown) for securing the sash 14 to the frame are unlocked. The sash 14 can therefore be pivoted relative to the frame 12.

[0045] Figure 7 The figure also shows the opening limiting device 40 in its corresponding position. The switching rod 42 is in a second switching position corresponding to the second actuation position of the handle 38, in which the locking section 74 is displaced away from the recess 65 (and thus no longer closes the recess 65 of the notched plate 44). The pin 60 is located in the guide groove 62 between the switching rod wall section 75 and the wall section 78.

[0046] In Figure 8The wing 14 was pivoted relative to the frame 12 into the partially open position. The handle 38 is in the second operating position (90° position). Figure 8 Figure 1 also shows the opening limiting device 40 in its corresponding position. The switching rod 42 is in the second switching position corresponding to the second actuation position of the handle 38, in which the locking section 74 is displaced away from the recess 65. By pivoting the wing 14, the arm 71 of the scissor arm 46 was also pivoted, whereby the pin 60 was moved through the guide groove 62 and is arranged at the closed end 64 of the guide groove 62 in the recess 65 of the notched plate 44. The movement of the pin 60 is also shown in Figure 4b illustrated.

[0047] Figure 9The figure shows the wing arrangement 10 in the partially open position, with the handle 38 pivoted back into the first operating position (0° position or closed position). Figure 9 The opening limiting device 40 is also shown in its corresponding position. The switching rod 42 is in the first switching position, in which the locking section 74 of the notched plate 44 is located in front of the recess 65, thus closing the recess 65. The pin 60 of the scissor arm 46 is therefore trapped in the recess 65 and cannot be moved out of it. Thus, the sash 14 is locked in the partially open position relative to the frame 12 via the scissor arm 46 (see also Figure 4a ).

[0048] In the Figures 10 to 12 Figure 10 illustrates a complete opening of the wing arrangement.

[0049] Figure 10 The wing arrangement 10 in the closed position is shown analogously to Figure 6The opening limiting device 40 is also in Figure 10 in the corresponding position analogous to Figure 6 As shown. To avoid repetition, please refer to the explanations provided there.

[0050] In Figure 11 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 devices (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.

[0051] Figure 11The opening limiting device 40 is also shown in its corresponding position. According to the third actuation position of the handle 38, the switching rod 42 is in a third switching position in which the pin 60 is located in the guide groove 62, but outside the gap between switching rod wall section 75 and notch plate 44, as well as outside of switching rod wall section 75 and wall section 78. The pin 60 is therefore not guided by either the notch plate 44 or the wall section 78 on the side opposite switching rod wall section 75 (see also Figure 4c If the wing 14 is pivoted relative to the frame 12 in the direction of the open position, the scissor arm 46 does not change its position.

[0052] Figure 12The wing arrangement 10 is shown in the open position, i.e., the wing 14 has been pivoted relative to the frame 12 into a position further than the partially open position, whereby in the example the wing 14 has been pivoted relative to the frame 12 by an angle of approximately 70°.

[0053] Figure 12 The opening limiting device 40 is shown in its corresponding position. By pivoting the sash 14, the notched plate 44 and the switching rod 42, which are arranged on the sash 14, are pivoted away from the scissor arm 46, which is arranged on the frame 12. The sash 14 can thus be pivoted relative to the frame 12 like a conventional casement window.
