Description

The invention relates to a building locking device for a building, comprising a first frame element designed and configured for arrangement on the building and a second frame element pivotably mounted relative to the first frame element in a first pivot angle range about a first pivot axis and in a second pivot angle range about a second pivot axis spaced parallel to the first pivot axis. For example, the prior art document EP 0 679 776 A1 describes a roof window with a sash mounted on the frame by means of spring-loaded support arms, in which the support arms are pivotally mounted at one end to a hinged bearing attached to the upper edge of the frame, and at the other end approximately at the center of the sash height to a pivot bearing on the side mullion of the sash, and the sash is provided with a pivot pin on each side mullion between the pivot bearing and its upper edge for interaction with a U-shaped guide rail attached to the side leg of the frame, the cover plate of which, which defines a groove and is adjacent to the sash, overlaps the pivot pin in the pivot position of the sash, and in the closed and pivot positions of the sash the pivot pin is located outside the area of ​​the cover plate.When a handle attached to the wing's cross member is actuated, the wing opens with the support arms coupled to the wing, causing it to fold around the hinges. When the wing is opened with the support arms decoupled from the arms, the pivot pins move in the groove of the guide rail towards the lower edge of the frame, lifting the wing-side pivot bearing from the frame to swing the wing open. The pivot pins are arranged to be longitudinally displaceable on the wing's side member, with the individual switching positions of the pivot pins being set by means of the handle. Furthermore, the publication DE 27 08 785 A1 discloses a sloping roof window with a frame and a sash, which is hinged at the longitudinal center of its vertical sections to a cover, which at the other end is pivotally arranged on the upper mullion of the frame about a pivot axis and can be folded up in a plane with the sash, with pivot pins fixedly arranged on the vertical sections between the top of the sash and the hinges, over which the sash can pivot and which are slidably mounted in the plane of the frame on its vertical mullions in such a way that, when the sash is opened, they slide from their upper bearing point downwards towards the lower mullion to their lower bearing point, with opening arms serving to open the sash, which are pivotally attached to the vertical mullions by means of a coil spring bearing, the coil spring force of which is adjustable by rotation of the axis and have a roller at the other free end,and with an operating handle located on the lower leg of the wing. Furthermore, the publication EP 0 649 966 A1 describes a roof window with a hinged sash, which is hinged to the frame around its horizontal upper side by means of a bearing element and held in each of its open positions by spring-like tilting elements, such as gas-pressure telescopic springs. It is provided that the bearing elements are attached to support members on both sides and that the support members are slidably arranged in guide rails that can be attached to the frame for lowering the opened hinged sash into a cleaning position. Reference is also made to publication EP 2 525 013 A2, which describes a holding device for the sash frame of a roof window comprising a frame and the sash frame. This device includes at least one first guide associated with the frame, which, during normal operation of the roof window, guides at least one follower associated with the sash frame; a cleaning safety device associated with the frame, which, during cleaning of the roof window, secures the follower to fix the sash frame in the cleaning position; and a second guide associated with the frame, which, during installation of the sash frame, supports the follower and guides it into the first guide. The cleaning safety device is provided that it is arranged at least partially within a cavity, with the second guide extending at least partially over the cavity or a portion thereof. Furthermore, a window is known from German patent application DE 2 421 919 A, particularly for installation in a sloping roof. This window has a sash frame that can be tilted from its closed position about a horizontal axis. This axis is oriented such that the upper part of the sash frame moves inwards relative to the plane of the window frame during the tilting movement. The sash and window frame are connected to each other by two hinges attached in or to the side joints of the window. The hinges are pivotally connected to the sash frame at or near the lower sash frame section, and to the window frame at or near the center of the side sections of the window frame. The tilting axis between the sash and window frame is laterally displaceable relative to one of these window sections, primarily parallel to the plane of that section. Further state of the art is known from publication US 4007558 A. The object of the invention is to propose a building locking device for a building which has advantages over known building locking devices, in particular being characterized by particularly convenient operation and easy handling, especially during cleaning. This is achieved according to the invention with a building locking device for a building with the features of claim 1. It is provided that a first guide rail is arranged on the first frame element and a second guide rail is arranged on the second frame element, wherein a guide element engages in the first guide rail both independently of a first pivot angle of the second frame element relative to the first frame element lying within the first pivot angle range and independently of a second pivot angle of the second frame element relative to the first frame element lying within the second pivot angle range. The engagement is permanent, in particular displaceable, preferably sliding and / or rolling. Advantageous embodiments with expedient further developments of the invention are specified in the dependent claims. It should be noted that the exemplary embodiments described in the description are not limiting; rather, any variations of the features disclosed in the description, the claims, and the figures are possible. The building closure device is designed and intended for installation on or in a building. The building has a building envelope in which a building envelope opening is created. The building envelope lies between the building's exterior environment and its interior, thus separating them. The building envelope is preferably designed as a wall or roof. The building envelope opening is therefore either a wall opening or a roof opening. The building closure device is installed in this building envelope opening. The building closure device serves to close the building, at least temporarily, and in particular to close the building envelope opening formed in the building envelope, at least temporarily. The building closure device is designed as a window, preferably as a roof window or skylight, in particular as a residential roof window or skylight. Consequently, the building envelope opening is specifically a roof opening. The building closure device is designed to allow light to pass through the building envelope opening and is therefore at least partially and in certain areas translucent. For this purpose, the building closure device has translucent glazing, which is designed, for example, as single glazing or as multiple glazing, in particular as double glazing or triple glazing. The building closure device comprises several frame elements, namely the first frame element and the second frame element. The first frame element can also be referred to as the frame and the second frame element as the sash frame of the building closure device. Each frame element has several frame members. The frame members are attached to one another in such a way that they enclose a section of the building closure device between them. The frame members thus each form a closed frame or a closed frame element. The frame elements, or the multiple frame members, are designed in particular such that they overlap and / or cover the building envelope opening. Preferably, the frame members are arranged and designed in such a way that they, especially together with the glazing, at least temporarily, and preferably completely, close the building envelope opening.For this purpose, the glazing is supported by the second frame element. For example, it is framed by the frame member of the second frame element. The building locking device is openable and closable, meaning it can be opened and closed, and is designed accordingly. Consequently, the building locking device can exist in different states in which the two frame elements of the building locking device are arranged differently relative to each other. For example, the building locking device is closed in a first state and at least partially or even completely open in a second state. The first state can therefore also be referred to as the closed state and the second state as the open state. In the first state of the building locking device, particularly in the closed state, an opening bounded by the first frame element is further closed by the second frame element than in the second state, particularly in the open state.Preferably, the opening of the first frame element is completely closed by the second frame element in the closed state, in particular together with the glazing. The second frame element is movable relative to the first frame, more precisely pivotable or rotatable. For this purpose, the second frame element is pivotally mounted about two pivot axes, namely the first and second pivot axes, preferably on the first frame element. This means that the two frame elements are pivotally mounted relative to each other about several different pivot axes, namely at least or exactly two pivot axes. The pivot axes are arranged parallel to and spaced apart from each other. The first pivot axis is designed as a hinge axis for a hinged opening, and the second pivot axis as a pivot axis for a pivot opening. The building closure device, designed as a window, can therefore be described as a tilt-and-turn window. Typically, when the building locking device is properly installed, the first pivot axis is located in the upper third of the device, while the second pivot axis is located approximately in the center. For example, relative to the distance between two crossbeams of the first frame element, the first pivot axis is at most 20%, at most 10%, or at most 5% away from one of the crossbeams, particularly the upper one. The second pivot axis, on the other hand, is at least 30% or at most 70%, at least 40% and at most 60%, or approximately or exactly 50% away from one of the crossbeams. The hinged opening of the building locking mechanism, i.e., the pivoting of the second frame element around the first pivot axis, has the advantage of creating a comparatively large, continuous opening. It is typically used to move the second frame element between the closed and open positions. The pivot opening, on the other hand, is typically used to position the building locking mechanism, or the second frame element, in a cleaning position where a side of the second frame element and / or the glazing that would otherwise face the outside is now facing the interior. Preferably, the building locking device is designed such that the swing-opening action, i.e., the pivoting of the second frame element relative to the first frame element about the second pivot axis, is only permitted from the open position. To move the second frame element into the cleaning position, it is therefore necessary to first pivot it from the closed position about the first pivot axis into the open position, and then pivot it from the open position into the cleaning position about the second pivot axis. This is achieved, for example, using a pivoting arm arrangement. This type of building locking mechanism is extremely flexible and easy to clean. However, in known building locking mechanisms, the second frame element is at least temporarily unguided while being moved from the open position to the cleaning position. This can make handling the building locking mechanism more difficult and may confuse the user, as it creates the impression that the second frame element is not securely held. For this reason, according to the invention, the first guide rail is assigned to the first frame element and the second guide rail to the second frame element. The guide element engages in both guide rails, i.e., both the first and the second guide rail, so that the two guide rails, and thus the two frame elements, are permanently connected to each other via the guide element. The guide rails are each designed to allow the guide element to move within them. The guide rails therefore do not fix the guide element in a specific position, but allow at least temporary movement of the guide element within the guide rails. This maintains the flexibility and ease of use of the building closure element, especially during the folding opening phase. At the same time, the swing opening mechanism is improved, as the two frame elements are permanently connected to each other via the guide element, specifically away from the first and second pivot axes. This means that the guide element always engages the frame elements at a distance from both the first and second pivot axes, thus coupling the frame elements together in addition to their bearing arrangement around the first and / or second pivot axes. The connection between the frame elements via the guide element exists independently of the first and second pivot angles. The first pivot angle is the angle at which the second frame element is positioned relative to the first frame element with respect to the first pivot axis. The second pivot angle, accordingly, refers to the angle at which the second frame element is positioned relative to the first frame element or relative to the extension arm assembly with respect to the second pivot axis. The building locking device is designed to allow the frame elements to shift, with the first pivot angle falling within the first pivot angle range and the second pivot angle falling within the second pivot angle range. The pivot angle ranges, i.e., the first and second pivot angle ranges, are understood to be those that occur during the intended use of the building locking device. During normal use, particularly when the building locking device is not in operation, maintenance, or repair, the first pivot angle remains permanently within its first range, and the second pivot angle remains permanently within its second range. This described design of the building locking device achieves the aforementioned advantages; in particular, the device is exceptionally easy and convenient to operate. A further development of the invention provides that the second frame element is pivotably mounted about the first pivot axis relative to the first frame element and about the second pivot axis relative to the pivot arm assembly via a support arm arrangement, wherein the support arm arrangement is pivotably mounted on the second frame element about the first pivot axis relative to the first frame element and about the second pivot axis relative to the second frame element. The support arm arrangement serves to pivotally mount the second frame element. Accordingly, the second frame element is mounted relative to the first frame element by means of the support arm arrangement. Preferably, the extension arm assembly is pivotally mounted on the first frame element about the first pivot axis. This means that the second frame element, together with the extension arm assembly, is pivotable about the first pivot axis relative to the first frame element. Additionally, the second frame element is pivotally mounted about the second pivot axis relative to the extension arm assembly, particularly on the extension arm assembly itself. Preferably, the extension arm assembly is pivotally mounted on the first frame element via a first pivot bearing of the building locking device, while the second frame element is pivotally mounted on the extension arm assembly by means of a second pivot bearing. The pivot bearings are located, in particular, at opposite ends of the extension arm assembly, so that ultimately the extension arm assembly is pivotably mounted on the first side, i.e., on a first side, about the first pivot axis relative to the first frame element, in particular on the first frame element, and, in addition, on the other side, i.e., at another end, pivotably mounted on the second frame element about the second pivot axis by means of the second pivot bearing. The extension arm arrangement preferably comprises several extension arms, which are spaced apart from one another and mounted on the second frame element. For example, the extension arms are mounted on spaced-apart, parallel frame members of the second frame element, each pivoting about the second pivot axis. The use of the extension arm arrangement enables convenient operation of the building locking device. A further development of the invention provides that an opening scissor mechanism is rotatably mounted on an opening carriage, which is guided on the first frame element within a carriage displacement range, about a first opening pivot axis, and on the opening arm assembly about a second opening pivot axis. The opening scissor mechanism serves to further simplify the operation of the building locking device, in particular the folding opening. Preferably, the second frame element is supported with respect to the first frame element if the second frame element is arranged in a position other than its closed position, in particular in the open position. The opening scissor mechanism is rotatably mounted on the opening carriage and on the opening arm assembly. The opening carriage is guided on the first frame element in a way that allows for displacement, in particular linear displacement, within the carriage displacement range. During normal operation of the building locking device, the opening carriage is always within its movement range. Due to the movable guide of the opening carriage, one axis of rotation, around which the opening scissor mechanism is rotatably mounted on the opening carriage, is displaceable relative to the first frame element. A second axis of rotation, around which the opening scissor mechanism is rotatably mounted on the opening arm assembly, is, however, fixed relative to the opening arm assembly. In principle, a reverse configuration is also possible, in which the first opening axis of rotation is stationary relative to the first frame element, whereas the second opening axis of rotation is displaceable relative to the opening arm assembly, particularly by means of a displaceable guide for the opening carriage on the opening arm assembly.In any case, reliable support is achieved in operating the building locking device. A further development of the invention provides that the first guide rail forms a guide for the extension carriage, at least in part, so that the extension carriage is guided in a displaceable manner by the first guide rail. The first guide rail thus has a dual function. On the one hand, it guides the guide element, by means of which the frame elements are permanently connected to each other, namely at a distance from the two pivot axes. Additionally, however, it serves to guide the extension carriage; for example, the carriage rests against it in a sliding manner, at least temporarily. For example, the guide element engages in the first guide rail, while the extension carriage rests against the outside of the guide rail in a sliding manner. Accordingly, additional guidance of the extension carriage can be omitted, or the guidance of the extension carriage can also be used to support the guide element. A further development of the invention provides that, in a folding position of an adjustment device, the second frame element is fixed relative to the extension arm assembly about the second pivot axis, and in a cleaning position of the adjustment device, it is released to pivot relative to the extension arm assembly about the second pivot axis. The user selects a setting from several options on the building locking device, in particular by means of an operating element of the building locking device, for example, an operating handle. Preferably, the operating element is displaceable, in particular rotatable, and mounted on the second frame element. The multiple settings include at least the tilt setting and the cleaning setting. Additionally, a locking setting may be provided in which the frame elements are fixed relative to each other in their closed position, thus preventing any movement from the closed position towards the open position and / or the cleaning position. In the tilt setting, the building locking device is adjusted so that the second frame element is fixed relative to the extension arm assembly, particularly with respect to the second pivot axis. Movement of the second frame element is therefore only permitted in conjunction with the extension arm assembly, namely around the first pivot axis. In the tilt setting, the second frame element can be moved from the closed position towards the open position or vice versa. If, however, the cleaning setting is selected and adjusted, the adjustment mechanism releases the second frame element relative to the extension arm assembly with respect to the second pivot axis, thus allowing the second frame element to pivot about the second pivot axis. Preferably, in the cleaning setting, both the pivoting of the extension arm assembly relative to the first frame element about the first pivot axis and the pivoting of the second frame element relative to the extension arm assembly with respect to the second pivot axis are permitted. This also serves to achieve particularly flexible operation. A further development of the invention provides that the guide element is guided by means of the first guide rail along a first displacement path within a first displacement area and by means of the second guide rail along a second displacement path within a second displacement area, wherein the first displacement path has a greater length than the second displacement path. The guide element is mounted using the first guide rail such that movement is permitted only along the first displacement path. The same applies to the second guide rail, which permits displacement of the guide element only along the second displacement path. During normal use of the building locking device, the guide element moves along the first displacement path within the first displacement zone and along the second displacement path within the second displacement zone. The displacement zones encompass all positions of the guide element occurring during normal use along both the first and second displacement paths. The guide rails are designed and the displacement zones are selected such that the first displacement path is longer than the second. In other words, a greater degree of displacement of the guide element is permitted along the first displacement path than along the second. This reliably prevents instability during the movement of the second frame element relative to the first. A further development of the invention provides that the first displacement section and the second displacement section are angled relative to each other in at least one first position of the first frame element and the second frame element, and / or run parallel to each other in a second position of the frame element and the second frame element. The first displacement section and the second displacement section always overlap where the guide element is arranged within them. Accordingly, a first position of the first displacement section, where the guide element is located in the first guide rail, overlaps with a second position of the second displacement section, where the guide element is located in the second guide rail. At the points defined above, the displacement sections in the first position of the frame elements are angled relative to each other, thus forming an angle greater than 0° and less than 180°. In the second position of the frame elements, the displacement sections at these points are aligned parallel. The described alignments preferably apply to tangents that define the paths of the guide rails at these points. This design of the building locking device, in turn, enables simple and convenient operation. A further development of the invention provides that the first guide rail is a linear guide rail, such that the first displacement section is continuously straight, and / or that the second guide rail is a linear guide rail, such that the second displacement section is continuously straight, or a curved guide rail, such that the second displacement section is curved at least partially, and in particular continuously. The first guide rail is preferably always designed as a linear guide rail, so that the first displacement section is continuously straight. In particular, the first guide rail extends along a vertical member of the first frame element. Specifically, the first guide rail and the first displacement section extend over at least 60%, at least 70%, or at least 80% of the vertical member, thus overlapping it for the most part. The second guide rail is designed either as a linear guide rail or as a curved guide rail. In the case of a linear guide rail, the second displacement section is continuously straight; if the second guide rail is a curved guide rail, the second displacement section is curved, at least in part, and thus has a non-zero radius of curvature. Particularly preferably, the second displacement section is continuously curved, meaning the radius of curvature is non-zero over its entire length. Particularly preferably, the radius of curvature is identical over the entire length of the second displacement section; however, a continuous change in the radius of curvature over the second displacement section is also possible. The design of the second guide rail as a linear guide rail allows for particularly flexible handling of the building locking device during the arrangement of the second frame element in the cleaning position, since the second guide rail is preferably arranged such that the second frame element is vertically adjustable, and in particular, can be moved into the interior. The curved design of the second movement section enables particularly comfortable and smooth operation of the building locking device. Preferably, the second guide rail and the second movement section are arranged at an angle relative to a frame member of the second frame element. In particular, they are at an angle to a longitudinal center axis of the frame member, especially a vertical member, which is greater than 0° and less than 180°. Such an angle enables particularly simple and comfortable operation. A further development of the invention provides that the second displacement section is curved around the first pivot axis in at least one position of the second frame element relative to the first frame element. This means that the second displacement section is curved in the direction of the first pivot axis, for example, lying on a circular path that encompasses the first pivot axis. Preferably, the circular path is arranged off-center relative to the first pivot axis; that is, the first pivot axis is positioned at a distance from the center point of the circular path. Such a curvature of the second displacement section, in turn, enables particularly convenient operation of the building locking device. A further development of the invention provides that the first guide rail and the second guide rail are designed such that pivoting the second frame element about the second pivot axis causes the support arm assembly to pivot about the first pivot axis relative to the first frame element. This means that pivoting the frame elements about the second pivot axis, or pivoting the second frame element about the support arm assembly about the second pivot axis, additionally causes the support arm assembly to pivot about the first pivot axis, namely due to the coupling of the two guide rails via the guide element. This clearly demonstrated the existence of a closed kinematic chain, with the two frame elements rotatably mounted to each other at spaced-apart bearing points. Specifically, the second frame element is directly connected to the first via the guide element and indirectly via the extension arm assembly. More precisely, the second frame element is pivotally mounted on the extension arm assembly about the second pivot axis, and the extension arm assembly, in turn, is pivotally mounted about the first pivot axis relative to and / or on the first frame element. This ensures particularly reliable and rigid guidance of the second frame element during the swing-opening phase, reliably preventing or at least reducing any tilting of the second frame element due to twisting of the extension arm assembly. A further development of the invention provides that the displacement of the guide element along the first displacement path, occurring across both the first and second pivot angle ranges, is greater than the displacement of the guide element along the second displacement path, also occurring across both the first and second pivot angle ranges. Accordingly, the building locking device is designed such that during the swing-opening phase, a comparatively small displacement of the guide element occurs along the second displacement path, whereas the displacement of the guide element along the first displacement path is greater.For example, the length of the first displacement section, or the resulting displacement of the guide element along the first displacement section, is greater by a factor of at least 5, at least 10, or at least 20 than the length of the second displacement section, or the resulting displacement of the guide element along the second displacement section. This design achieves a rigid and torsion-resistant guide for the second frame element. A further development of the invention provides that the first guide rail is closed at least over the first displacement section, preferably continuously, and the second guide rail is closed at least over the second displacement section, preferably continuously, so that the guide element is continuously guided in the first and second guide rails. This means that the respective guide rail is closed continuously at least along the respective displacement section, so that the guide element is positively locked in the guide rail. This is particularly preferably also the case beyond the respective guide section, for example by a corresponding closure of the guide rail, so that the guide element cannot come out of the guide rail regardless of the position of the frame elements relative to each other. The guide element therefore cannot disengage from the guide rail.Preferably, this applies to both guide rails, which are designed accordingly. It is particularly preferred that the guide element be inserted into the second guide rail and that the second guide rail be arranged on the second frame element in such a way that the guide element is subsequently held captive by the second guide rail. In particular, the guide element is held by the second frame element in the second guide rail and by the second guide rail on the second frame element. Subsequently, the guide element is also inserted into the first guide rail, and the second frame element is supported relative to the first frame element, in particular connected to the first frame element. It can be provided that the guide element is reliably held in the first guide rail simply by the bearing of the second frame element against the first frame element and the resulting limitation of the second frame element's displacement relative to the first frame element. However, it is particularly preferred to close a recess through which the guide element is inserted into the first guide rail after this insertion, in order to reliably prevent the guide element from disengaging from the first guide rail. Accordingly, a particularly high level of security for the building locking device is achieved. A further development of the invention provides that the guide element in the first guide rail is continuously freely displaceable along the first displacement path, and / or that the guide element in the second guide rail is held in at least one position along the second displacement path by means of a fixing device, in particular by a locking or magnetic mechanism. The first guide rail is designed such that it guides the guide element along the first displacement path without obstruction, i.e., it does not fix the guide element in place. For example, the first guide rail has end stops for the guide element on opposite sides, which limit the first displacement path, in particular enclose it between themselves. Additionally or alternatively, a holding device can be assigned to the first guide rail. This device is designed, in particular, to secure the guide element in a position along the first displacement path, especially by positive locking. For example, the holding device is adjustable and is temporarily in a release position and temporarily in a locking position. In the release position, it continuously releases the guide element along the first guide rail along the first displacement path; in the locking position, it secures the guide element in the position it is in along the first displacement path. For example, this position is located at one end of the first displacement path. The second guide rail is preferably associated with the fixing device. This device is designed and configured to fix the guide element in at least one position along the second displacement path, in particular by detenting or magnetically locking it in place. This means that the guide element can be freely moved along the second displacement path outside of the at least one position, namely by applying a specific displacement force. To move the guide element into the at least one position, a holding force of the fixing device must be overcome, so that moving the guide element requires a force greater than the displacement force. Once the guide element is in the at least one position, a force greater than the displacement force must again be applied to it to overcome the holding force and move it out of the at least one position. For example, the locking device is designed and configured to lock the guide element in only one position. However, it can also be provided that several such positions are spaced apart from each other along the second displacement path. In particular, the second guide rail is designed such that the guide element is in at least one position and is held in place by the locking device when the second frame element is in its cleaning position. Consequently, the second frame element is locked in the cleaning position, and the building locking device can be cleaned easily and conveniently. A further development of the invention provides that the fixing device is designed as an attachment, fixed to or integrated into the second guide rail, which secures the guide element in at least one position. The second guide rail itself does not have any fixing means, but allows the guide element to be moved uniformly along the second path of movement, particularly with a constant displacement force. The fixing device is implemented by attaching the attachment to the second guide rail. The attachment is designed to interact with the guide element, for example, by positive locking, and in particular by a detent mechanism, as long as the guide element is in at least one position. However, it can also be provided that the fixing device holds the guide element magnetically.Preferably, the second guide rail is made of metal and the attachment is made of a plastic, such as a thermoplastic, an elastomer, or the like. This allows for separate replacement of the attachment and consequently the fixing device, making maintenance and repair of the building locking mechanism simple and cost-effective. Particularly when the second guide rail is designed as a linear guide rail, it is preferably possible to adjust the second frame element vertically when it is in the cleaning position. Different cleaning positions can be achieved, or the cleaning position can be adjusted, by arranging the guide element differently relative to the second guide rail. Preferably, the fixing device is designed and configured to lock the guide element in several different positions along the second displacement path, in particular by detent or magnetic locking. For example, at least two such positions are available, but there can also be at least three or at least four positions in which the fixing device temporarily locks the guide element relative to the second guide rail.This results in particularly flexible handling of the building locking device. A method for operating a building locking device for a building, in particular a building locking device in accordance with the explanations in this description, is also disclosed, wherein the building locking device has a first frame element designed and configured for arrangement on the building and a second frame element pivotably mounted with respect to the first frame element in a first pivot angle range about a first pivot axis and in a second pivot angle range about a second pivot axis spaced parallel to the first pivot axis. It is provided that a first guide rail is arranged on the first frame element and a second guide rail is arranged on the second frame element, into which a guide element permanently engages, in particular displaceably, preferably sliding and / or rolling displaceably, regardless of a first pivot angle of the second frame element lying in the first pivot angle range relative to the first frame element and regardless of a second pivot angle of the second frame element lying in the second pivot angle range relative to the first frame element, so that by pivoting the second frame element about the second pivot axis a pivoting of the second frame element about the first pivot axis is effected. The advantages of such a design for the building locking device and such a procedure have already been mentioned. Both the building locking device and the procedure for operating it can be further developed as explained in this description, and reference is made to these explanations in that regard. The features and combinations of features described in the description, in particular those described in the following figure description and / or shown in the figures, can be used not only in the combinations specified, but also in other combinations or individually, without departing from the scope of the invention, in particular the scope of the claims. Thus, embodiments that are not explicitly shown or explained in the description and / or the figures, but which emerge from or can be derived from the explained embodiments, particularly within the scope of the claims, are also to be considered as encompassed by the invention. The invention is explained in more detail below with reference to the exemplary embodiments shown in the drawing, without limiting the invention. Figure 1 shows a schematic side view of a building locking device for a building with a first frame element and a second frame element, wherein the second frame element is arranged in a closed position; Figure 2 shows a schematic side view of the building locking device, wherein the second frame element is in an open position; Figure 3 shows a schematic side view of the building locking device, wherein the second frame element is in an intermediate position on its way to a cleaning position; Figure 4 shows a schematic side view of the building locking device, wherein the second frame element is arranged in the cleaning position.Fig. 5 a schematic sectional view through the building locking device, showing a first guide rail by means of which a guide element and an extension slide are guided in a displaceable manner, and Fig. 6 a schematic representation of a second guide rail with a guide element guided therein, wherein the guide element is held in a latching position using an attachment part arranged on the second guide rail. Figure 1 shows a schematic representation of a building closure device 1, designed as a roof window or skylight. The building closure device 1 has a first frame element, which is a fixed frame, and a second frame element 3, which is a sash frame. The two frame elements 2 and 3 are pivotally mounted to each other about a first pivot axis 5 by means of a first pivot bearing 4. More precisely, a tilt arm assembly 6, of which one tilt arm 7 is shown here, is pivotally mounted about the first pivot axis 5 on the first frame element 2 via the first pivot bearing 4. The extension arm assembly 6, or rather its extension arm 7, is in turn pivotally mounted on the second frame element 3 by means of a second pivot bearing 8 about a second pivot axis 9. Overall, the second frame element 3 is therefore pivotable relative to the extension arm assembly 6 about the second pivot axis 9, and the extension arm assembly 6 is pivotally mounted relative to the first frame element 2 about the first pivot axis 5, so that the second frame element 3 is pivotally mounted relative to the first frame element 2 about both the first pivot axis 5 and the second pivot axis 9. The building locking device 1 also has an extension scissor 10, which is pivotally connected to an extension carriage 11 about a first extension axis and to the second frame element 3 about a second extension axis. The extension carriage 11 is mounted on the first frame element 2 so as to be linearly displaceable, preferably by means of a first guide rail 12, which is arranged on the first frame element 2 and is in particular attached to a frame member of the first frame element 2. The first guide rail 12 thus forms, at least in part, a guide 13 for the extension carriage 11. The first guide rail 12 also defines a first displacement path 14 for a guide element 15, which is not shown here. The guide element 15 is displaceably mounted in the first guide rail 12 along the first displacement path 14 and in a second guide rail 16 along a second guide path 17. It is particularly important that the guide element 15 is guided in the guide rails 12 and 16 during normal operation of the building locking device 1, and in particular, regardless of the position of the second frame element 3 relative to the first frame element 2 during normal operation. This means that the second frame element 3 is never in a position outside of either the guide rails 12 or 16 relative to the first frame element 2. This means that the two frame elements 2 and 3 are pivotably mounted to one another via the first pivot bearing 4, the extension arm assembly 6, and the second pivot bearing 8, and via the guide element 15, which engages in both the first guide rail 12 and the second guide rail 16 and is guided by them along the respective displacement sections 14 and 17, respectively. In the illustrated embodiment, the first guide rail 12 is a linear guide rail, and the second guide rail 16 is a curved guide rail. Accordingly, the first displacement section 14 is completely straight, whereas the second displacement section 17 is curved, at least in some areas, but preferably continuously as shown here. The building locking device 1 also has an operating element 18, which is in the form of a handle. Fig. 2 shows a schematic representation of the building locking device 1, wherein the second frame element 3 is arranged in an open position, in particular in a hinged opening position, relative to the first frame element 2. For hinged opening, i.e., for moving the second frame element 3 from the closed position to the hinged opening position, the second frame element 3 is fixed relative to the pivot arm assembly 6; thus, no pivoting movement about the second pivot axis 9 is permitted. However, the pivot arm assembly 6 is pivoted about the first pivot axis 5, so that the second frame element 3 is moved together with the pivot arm assembly 6. It is evident that when the second frame element 3 pivots from the closed position to the hinged open position, the guide element 15 is permanently engaged with the first guide rail 12 and the second guide rail 16, thus moving along the first displacement path 14 and along the second displacement path 17. It is further evident that the first displacement path 14 has a significantly greater length than the second displacement path 17. The hinge scissor mechanism 10 is not shown for clarity. The hinged open position can also be referred to as the open position. Fig. 3 again shows a schematic representation of the building locking device 1, but now the second frame element 3 is in an intermediate position. This intermediate position is achieved by releasing the second frame element 3 to pivot relative to the extension arm assembly 6 about the second pivot axis 9 when it is in the hinged open position. Preferably, in the intermediate position, the extension arm assembly 6 is in the same position relative to the first frame element 2 as it is in the hinged open position, so that only a displacement of the second frame element 3 relative to the extension arm assembly 6 about the second pivot axis 9 has occurred. This displacement is permitted by a displacement of the guide element 15 along the displacement path 14 and 17, i.e., in the guide rails 12 and 16. Fig. 4 shows another schematic representation of the building locking device 1, with the second frame element 3 now in a cleaning position. Some elements, such as the second pivot bearing 8, are not shown for clarity. The cleaning position is reached from the intermediate position by moving the second frame element 3 such that the guide element 15 moves along the first displacement path 14. Preferably, the first guide rail 12 has retaining means (not shown here) for securing the guide element 15 in the first guide rail 12. With the guide element 15 secured by means of the retaining means, movement of the frame element 3 is only permitted to the extent that this movement of the guide element 15 along the second displacement path 17, i.e., in the second guide rail 16, is permissible.By fixing the guide element 15 in the position shown, the second frame element 3 is held in the cleaning position and can be easily and effortlessly cleaned. Figure 5 shows a schematic sectional view of the building locking device 1. Visible is a glazing 19, which is supported by the second frame element 3. It is also evident that the first guide rail 12 forms the guide 13 for the tilting carriage 11, in particular guiding it at least laterally. The first displacement section 14 is defined by a C-profile of the first guide rail 12. The guide element 15 engages in this profile and is held in it by means of the second guide rail 16. The second guide rail 16 is, for example, designed in multiple parts and consists of a guide profile 20 and a guide plate 21. The displacement section 17 is defined in the guide profile 20 in the form of a recess. The guide plate 21 closes this recess on the rear side, i.e., on the side facing away from the first guide rail 12.Since the guide element 15 has a retaining collar, it is held captive between the guide profile 20 and the guide plate 21. Figure 6 shows a schematic representation of the second guide rail 16 and the second displacement section 17 defined by it. Also shown is the guide element 15, which is arranged in the second guide rail 16. It can also be seen that an attachment 22 is present on the second guide rail 16. This attachment is made of a different material than the second guide rail 16, preferably a plastic, for example, an elastomer. The attachment 22 forms a fixing device or locking device 23 by forming an elastically deformable locking lug 24, which, in the position of the guide element 15 shown, interacts with it to hold it, in particular to lock it in place, i.e., to secure it with respect to the second guide rail 16. The use of the fixing device 23 enables the second frame element 3 to be reliably fixed in the cleaning position.
