Definitions

• the invention relates to a wing arrangement having the features of the preamble of claim 1.
• 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 features 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 reliably limited to a partially open position.
• a pin engages with a guide groove, whereby a The head section of the pin can penetrate a corresponding recess and is engaged by a projection, thus being trapped.
• the locking mechanism of the scissor arm on the guide plate is comparatively rigid. This type of locking mechanism also places high demands on the dimensional accuracy of the individual components to ensure proper interaction.
• the rigid locking mechanism may mean that the opening limiter can only be installed between the upper wing and upper frame cross member, or between the lower wing and lower frame cross member, relative to the direction of gravity.
• the invention is based on the objective of enabling a flexibly applicable opening limitation in wing arrangements using structurally simple means.
• 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.
• 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).
• 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.
• 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).
• a reliable opening limiter is created using simple design means with a small number of components that are easy to manufacture and assemble. This contributes to a simple and cost-effective design of a wing assembly.
• the recess formed in the notched plate facilitates the insertion of the pin with a certain degree of...
• the mechanism provides play so that the pin and, if applicable, the scissor arm can be moved or pivoted orthogonally to the central longitudinal axis of the pin. This simplifies assembly and allows for more flexible use of the opening limiter.
• 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.
• 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.
• the guide groove formed in the shift rod faces the frame (fixed frame) or runs along the central longitudinal axis.
• the pin is open, allowing the pin of the frame-mounted scissor arm to engage in the guide groove.
• the guide groove is laterally bounded by the shift rod and the notched plate. As mentioned 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.
• the switching rod can have 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, thus trapping the pin in the recess.
• the pin is then located in the recess, and the locking section prevents the pin from dislodging it.
• the guide groove on the shift rod can be advantageously designed such that the guide groove (transverse to the longitudinal direction) is bounded on one side by a section of the shift rod wall 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.
• the switching rod can have a groove section through which the pin can pass when the sash pivots between a closed position and a partially open position.

• 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.
• 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 allow space between the pin (and, if applicable, any head section of the pin)
• 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).

• the tab can be wider (orthogonally to the longitudinal direction) than the switching rod.
• the shift rod can rest against the edge of the wing groove on one side for guidance and against the notched plate on the opposite side.
• the shift rod can be referenced to a plane that intersects the shift rod and whose The normal vector extends along the longitudinal direction of the guide groove and can be symmetrically designed.
• 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. Therefore, separate left- and right-hand versions of the switching rod are not required.

• 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.
