Description

[0001] The present application relates to a door leaf for a front door, shop door, or the like according to the preamble of claim 1. Furthermore, the present application relates to a system comprising a plurality of door leaves according to the preamble of claim 13. Furthermore, the present application relates to an automatic sliding door according to the preamble of claim 14. Furthermore, the present application relates to a method for producing a door leaf according to claim 15.

[0002] A door leaf according to the present invention can, in particular, be a sliding door leaf, which is used, for example, for an automatic sliding door. Such a sliding door leaf is generally suspended in a guide of the automatic sliding door and can be moved between a closed position and an open position by means of a motor. As a rule, a respective automatic sliding door is equipped with two sliding door leaves, each of which can be moved in a direction parallel to a respective leaf plane of the respective door leaf. In this way, the sliding door leaves can be alternately moved away from and towards one another, so that the automatic sliding door as such can be moved between a closed state and an open state.To open and close the automatic sliding door, the automatic sliding door can be equipped with presence sensors in a conventional manner that detect when a person approaches the automatic sliding door. A control system for the automatic sliding door then activates the drive, and the sliding door leaves are moved into their open position, allowing the person access to the building. The door leaf according to the present invention can be used for both an interior and an exterior door.

[0003] The door leaf according to the present invention comprises a flat leaf panel that extends parallel to a leaf plane of the door leaf. Furthermore, the door leaf comprises a door leaf profile that at least partially encloses the leaf panel at the edges. As a result, the leaf panel is mounted in or on the door leaf profile. State of the art

[0004] Door leaves of the type described above are already known in the prior art. Particularly for a door leaf intended for use in the form of a sliding door leaf, it is important that the leaf panel and the door leaf profile enclosing the leaf panel are arranged at least substantially flush. "Flush" (or "almost flush"), as used in this application, means the smallest possible offset between a respective outer surface of the leaf panel and a corresponding outer surface of the door leaf profile. This is because, for safety reasons, the offset must not exceed a certain maximum value to prevent injuries. Excessively large an offset would pose a risk of a person's hand or objects becoming trapped or caught in the area between the outer surface of the leaf panel and the door leaf profile.This can pose a risk of injury, particularly in the case of a sliding door leaf for an automatic sliding door, since the automatic sliding door automatically moves into an open position during operation and typically enters a drive-in area along a scraper edge. Injuries can occur when the sliding door leaf enters the drive-in area.

[0005] Therefore, it is recognized in the art that the aforementioned offset should be as small as possible, with a flush design as described above generally being preferred. Both in the art and for the purposes of this application, a design is considered flush or nearly flush if there is a minimal offset, measured perpendicular to the leaf plane, between the outer surface of the leaf panel and the corresponding outer surfaces of the door leaf profile.

[0006] In order to ensure minimal offset, the state of the art requires the use of differently dimensioned door leaf profiles for different leaf fillings, particularly different glass pane inserts. This is because the leaf fillings used can be designed differently depending on the requirements. This particularly applies to their thickness measured perpendicular to the leaf plane, which in the case of a leaf filling formed by a glass pane insert depends, for example, on how many individual glass panes the glass pane insert contains, the thickness of the individual glass panes, and the distance between the glass panes relative to one another. The respective door leaf profile must be dimensioned such that it lies as flush as possible with the outer surfaces of the glass pane insert. In practice, therefore, differently dimensioned door leaf profiles must be available for different leaf fillings.This means a great deal of effort in terms of warehousing.

[0007] To mitigate the problem, i.e., to reduce the number of different door leaf profiles, it is also common practice in the prior art to compensate for differences between the dimensions of the respective door leaf profile and the respective leaf filling using compensating elements. These can be formed, in particular, by rubber strips with which, for example, a glass pane insert is bordered at the edge in order to locally increase its thickness and thus adapt it to the dimensions of the respective door leaf profile. The desired flush surface is lost as a result, since the offset between the outer surface of the glass pane insert and the corresponding surface of the door leaf profile is increased by the amount applied by the compensating element in the thickness direction of the glass pane insert.

[0008] Document DE 31 02 921 A1 proposes a door or window sash in which the two profile half-shells of the respective sash profile can be continuously moved towards each other in a direction perpendicular to the sash plane. Lateral edging strips of the profile half-shells rest against the outer surfaces of the sash filling and thereby enclose it. The sash filling is formed by a plurality of individual glass panes that are not firmly connected to one another. By positioning the glass panes at a greater distance from one another than is usual with fixed glass pane inserts (e.g., double-pane insulating glazing or triple-pane insulating glazing), a larger volume of stagnant air is provided between the glass panes, which creates a thermally insulating effect. The profile half-shells are connected to one another via frame connecting elements.To ensure that the air space between the glass panes is airtight and that the air contained there can act as a stagnant layer of air to provide thermal insulation, the profile half-shells are sealed off from one another all the way around by means of a vapor-tight gasket. Any air contained between the glass panes is thus enclosed within the sash and cannot be exchanged with the outside world. The mobility of the profile half-shells relative to one another in a direction perpendicular to the sash plane enables flexible adaptation to the fluctuating volume of air trapped between the glass panes due to temperature fluctuations. This means that the profile half-shells, like the glass panes themselves, can move towards one another when the air volume between the glass panes decreases (when cooling down) and move away from one another when the air volume increases (when heating up). Task

[0009] The present application is therefore based on the object of providing a door leaf profile which enables the installation of various leaf fillings as flush as possible on both sides while keeping the storage of door leaf profiles as low as possible. Solution

[0010] The underlying object is achieved according to the invention with a door leaf having the features of claim 1. Advantageous embodiments emerge from the associated subclaims and the description.

[0011] As already explained above, the door leaf can in particular be formed by a sliding door leaf, which is preferably used for an automatic sliding door. The present invention therefore also extends to an automatic door comprising at least one door leaf according to the invention, which is designed as a sliding door leaf. Such an automatic door is therefore formed by an automatic sliding door. The door leaf can be used for both an exterior door and an interior door.

[0012] The door leaf comprises the flat leaf filling described above, which is oriented parallel to a leaf plane of the door leaf. The leaf filling can, for example, and preferably, be formed entirely by a glass pane insert, which in turn can, for example, and preferably, be formed by a glass pane package, for example in the form of double-pane insulating glazing or triple-pane insulating glazing. It is also conceivable for the leaf filling to be formed by a panel made of sheet metal, wood, plastic, or the like, wherein such a panel can, in turn, have one or more smaller glass pane inserts.

[0013] The leaf filling is preferably rigid in itself such that a distance measured perpendicular to the leaf plane between its two opposing outer surfaces cannot be changed as intended. In other words, in this embodiment, a thickness of the leaf filling measured perpendicular to the leaf plane is structurally fixed. Within the meaning of the present application, the leaf filling is not formed from several individual components that are systematically movable relative to one another in a direction perpendicular to the leaf plane during intended use of the door leaf - and thus of the leaf filling. If the leaf filling is formed from several individual components, these are preferably not movable relative to one another at all during intended use (regardless of the direction of movement).Deformations of the leaf filling, which occur, for example, as a result of pressure or temperature differences on the two sides of the door leaf, are not to be understood as such a movement within the meaning of the present application. If, for example, the leaf filling is formed by a glass pane insert in the form of a coherent glass pane package comprising several individual glass panes fixed relative to one another, these individual glass panes cannot be moved relative to one another when the door leaf is used as intended, neither in a direction perpendicular to the leaf plane nor in any other direction. However, this does not rule out the possibility that the individual glass panes may deform, in particular warp, for example under the influence of temperature.However, such curvatures or other deformations are not considered to be intended relative movement between the panes within the meaning of the present application, since the user cannot perform any planned movement of the individual panes relative to one another. In such glass pane packages (for example, in the form of double-pane insulating glazing or triple-pane insulating glazing), the individual glass panes are preferably firmly connected to one another at their peripheral edges and sealed against one another. Due to these connections, the thickness of the glass pane package, measured perpendicular to the sash plane, remains constant in an edge region of the package, even if the individual glass panes deform.

[0014] Furthermore, the door leaf comprises the door leaf profile described above, which at least partially encloses the leaf panel at the edge. Preferably, the door leaf profile completely encloses the leaf panel at the edge, so that the leaf panel is enclosed by the door leaf profile along its peripheral edge and thus supported in the door leaf profile. In the latter embodiment, the door leaf profile is designed like a frame, specifically in the sense that it frames the leaf panel all the way around. In this embodiment, the door leaf profile is also referred to in technology as a "leaf frame."

[0015] The leaf panel has two opposing outer surfaces, with its first outer surface facing a first side of the door leaf and a second outer surface facing a second side of the door leaf. When the door leaf is used for an external door, for example in the form of a front door or shop door, one of the outer surfaces of the leaf panel faces outwards, while the other outer surface faces inwards.

[0016] The door leaf profile comprises two profile half-shells and at least one insulating strip arranged between the profile half-shells. The insulating strip is firmly connected to the first profile half-shell. This can be achieved, in particular, in the form of a positive connection. For example, the insulating strip or a web part thereof has at least one dovetail-shaped connecting section that positively engages a complementarily shaped undercut of the first profile half-shell.

[0017] The insulating strip serves to thermally separate the profile half-shells and is positioned between them. Direct contact between the two profile half-shells is thus avoided. While the profile half-shells are preferably made of aluminum, the insulating strip, which is preferably made of plastic, is particularly important for improving the thermal transmittance of the door leaf profile. The insulating strip is assigned to an outer end face of the leaf panel. This end face runs around the outer edge of the leaf panel and is oriented perpendicular to the leaf plane.If the sash filling is formed, for example, by a glass pane insert, for example in the form of double-pane insulating glazing or triple-pane insulating glazing, the edge-side end faces of the individual panes of the sash filling and the seals located between the individual panes, by means of which the spaces between the individual panes are sealed gas-tight, are located on the edge-circumferential end face of the sash filling.

[0018] The profile half-shells each comprise a plurality of elongated profile parts, each having a longitudinal profile axis. For example, when the door leaf is in an installed state in which the leaf plane is oriented vertically, the profile half-shells can each comprise at least one horizontally oriented profile part and at least one vertically oriented profile part oriented perpendicular thereto. The door leaf profile is preferably designed such that it surrounds the leaf filling all the way around the edges, wherein in such a design the profile half-shells preferably each have at least four elongated profile parts, namely two horizontally oriented profile parts and two vertically oriented profile parts. In such a design the profile half-shells are each frame-like and configured to surround a circumferential edge region of a respectively associated outer surface of the leaf filling all the way around.Preferably, the profile parts of at least one of the profile half-shells are connected to one another in a force-transmitting manner, for example screwed or welded together.

[0019] The profile half-shells are designed in such a way that they each have a bordering strip by means of which an edge region of a respectively associated outer surface of the sash filling is bordered. In other words, an edge region of the first outer surface of the sash filling is bordered by means of a bordering strip of the first profile half-shell, while an edge region of the second outer surface of the sash filling is bordered by means of a bordering strip of the second profile half-shell. The respective bordering strip can in particular be a profile section of a respective profile part of the respective profile half-shell that protrudes in a direction parallel to the sash plane of the door leaf, protrudes in a direction parallel to the sash plane beyond the edge region of the sash filling and thus abuts or rests laterally against the respective outer surface of the sash filling.Since the two profile half-shells are each assigned to one of the outer surfaces of the sash panel, the profile half-shells with their edging strips are suitable for enclosing the sash panel in a direction perpendicular to the sash plane, so that the sash panel is positively held between the profile half-shells (more precisely: between the edging strips) in the direction perpendicular to the sash plane. The sash panel is thus fixed relative to the door leaf profile in the direction perpendicular to the sash plane.

[0020] The door leaf is further configured such that the second of the two profile half-shells is directly and / or indirectly engaged with the insulating bar, wherein the insulating bar is firmly connected to the first profile half-shell as described above. This engagement is designed to be non-positively connected in the direction perpendicular to the leaf plane. "Non-positively connected" in the context of the present application means that the two profile half-shells do not form a positive connection with one another in the direction perpendicular to the profile plane and are thus movable relative to one another, preferably continuously, in this direction. This results in the profile half-shells, as such, for example and particularly in an assembly situation, being non-destructively movable relative to one another in the direction perpendicular to the leaf plane and, in particular, do not lock with one another in this direction.Accordingly, the two profile half-shells can be joined together as such in a direction perpendicular to the sash plane without a form-fit connection and - although this is not intended - theoretically also separated from each other again. The joining can be achieved, for example, by the second profile half-shell and the insulating bar moving or being pushed into each other indirectly and / or directly in a direction perpendicular to the sash plane, without this resulting in a form-fit connection in the direction perpendicular to the sash plane, for example in the form of a protruding lug of one component snapping behind an edge of the other component or the like.

[0021] The distinction between indirect engagement and direct engagement of the second profile half-shell with the insulating web, within the meaning of the present application, is that in the case of direct engagement, the second profile half-shell comes into direct (and therefore immediate) contact with the insulating web, and in the case of indirect engagement, at least one further component connected to the second profile half-shell is placed between the insulating web and the second profile half-shell, which, as such, comes into direct contact with the insulating web and consequently "mediates" the contact between the insulating web and the second profile half-shell. Such a further component can, for example and preferably, be formed by a connecting device, which, for example, comprises at least one (further) insulating web and / or a plurality of individual connecting elements.Corresponding embodiments are explained separately below and can be found in the exemplary embodiments.

[0022] In principle, a design is also conceivable in which the engagement of the second profile half-shell with the insulating web occurs both directly and indirectly. For the purposes of the present application, this means, for example, that there is a section in which the second profile half-shell comes into direct and thus immediate contact with the insulating web, while at another point the contact occurs via the interposition of another component, for example, a connecting device placed between the second profile half-shell and the insulating web.

[0023] It is also conceivable that, in the area of ​​action of the connecting device, both a connecting device engages with the insulating bar (indirect engagement of the second profile half-shell with the insulating bar) and the second profile half-shell comes into direct contact or engagement with the insulating bar. For example, the second insulating bar with the connecting device can be pushed like a tongue into a profile section of the insulating bar designed like a groove, so that the connecting device engages directly with the insulating bar. In this case, the second profile half-shell can be moved so far towards the insulating bar or the first profile half-shell during assembly that an end of the second profile half-shell facing the insulating bar also comes into direct contact or engagement with the insulating bar.For example, one end of a spring-shaped profile section of a respective profile part of the second profile half-shell can also (i.e., in addition to the connecting device) extend somewhat into the groove-like profile section of the insulating web. A corresponding configuration can also be seen in the exemplary embodiment below.

[0024] For the inventive concept, it is harmless and can even be advantageous if the engagement between the second profile half-shell and the insulating web in the direction perpendicular to the sash plane forms a certain frictional connection, which makes movement of the two profile half-shells relative to each other in the direction perpendicular to the sash plane more difficult due to frictional forces occurring. Such a frictional connection can be caused, for example, by a press fit, whereby, for example, a tongue-shaped profile section of one component (for example, a connecting device) moves into a complementary groove-shaped profile section of the other component (for example, the insulating web) in the direction perpendicular to the sash plane, thereby forming a frictional connection between the tongue and groove.Such a configuration, within the meaning of the present application, does not have a positive connection in the direction perpendicular to the sash plane, so that the relative movement of the two profile half-shells to each other in the direction perpendicular to the sash plane is maintained without damaging the profile half-shells themselves, the insulating web, or other components used in the connection ("non-destructive"). However, the frictional connection means that, as intended, a deliberately generated static friction must first be overcome in order for a relative movement of the two profile half-shells in the direction perpendicular to the sash plane to occur.

[0025] Furthermore, the door leaf is designed such that the edging strips of the two profile half-shells are bonded to the corresponding outer surfaces of the leaf filling, at least in sections, preferably continuously. For this purpose, the profile half-shells are equipped with a double-sided adhesive tape on their edging strips, which, as the respective profile half-shell or a respective profile part thereof is arranged on the leaf filling, comes into adhesive contact with the respective outer surface of the leaf filling. In this way, the two profile half-shells are indirectly connected to one another, namely via the bond to the leaf filling. The door leaf profile is thus firmly attached to the leaf filling. The bonded connection is formed by a material-to-material connection.

[0026] The bond is designed in such a way that a force acting perpendicular to the sash plane on one of the profile half-shells can be transferred from the respective profile half-shell to the other profile half-shell via the bonding via the sash filling. Due to the non-positive or form-locking connection of the two profile half-shells to one another in the direction perpendicular to the sash plane (via the insulating web and possibly a connecting device), without the bond, a force flow between the two profile half-shells in the direction perpendicular to the sash plane would exist at most to a small degree via a possible frictional connection as explained above.Since the indirect and / or direct engagement of the second profile half-shell with the insulating bar (and, due to the fixed connection of the insulating bar to the first profile half-shell, effectively with the first profile half-shell) does not prevent the profile half-shells from moving relative to one another in a direction perpendicular to the sash plane, the basic idea of ​​the bonding is that the connection of the two profile half-shells in a direction perpendicular to the sash plane is achieved via the bonding of the edging strips to the sash filling. Thus, the two profile half-shells are each integrally connected to the sash filling via the respective bond. The profile half-shells are thus fixed in their distance relative to one another, measured perpendicular to the sash plane, as soon as they are bonded to the sash filling during assembly.

[0027] The door leaf according to the invention has many advantages. In particular, it enables a flush or nearly flush connection of the door leaf profile to the leaf panel on both outer surfaces of the panel. The idea is that during the assembly of the door leaf, the two profile half-shells can be moved closer to each other in a direction perpendicular to the leaf plane as needed until the edging strips of the profile half-shells, with the interposition of the adhesive, are nearly flush with the outer surfaces of the panel.In this arrangement, the offset measured perpendicular to the leaf plane between the respective outer surface of the leaf panel and an outer surface of the respective profile half-shell assigned to the respective outer surface and oriented parallel to the leaf panel consists solely of the sum of the thickness of the bond measured perpendicular to the leaf plane, on the one hand, and the thickness measured perpendicular to the leaf plane of that profile section of the respective profile part of the profile half-shell that locally forms the edging strip of the profile half-shell, on the other hand. This sum is only a few millimeters, preferably at most 8 mm, more preferably at most 4 mm, and even more preferably at most 3 mm, so that, according to general technical understanding and within the meaning of the present application, a "flush" or "virtually flush" connection of the door leaf profile to the leaf panel is achieved.This is to be understood as "flush on both sides," meaning that on both sides of the door leaf or on both outer surfaces of the leaf panel, the door leaf connects to the leaf panel with the aforementioned slight offset (and thus, within the meaning of this application, "flush" or "almost flush"). The design of the leaf panel (for example, in the form of a glass pane insert formed by a double-pane or triple-pane insulating glazing unit) as well as coating tolerances that may occur in the door leaf profile do not need to be taken into account. Any "glazing rubbers," i.e., compensating elements for a leaf panel formed by a glass pane insert, are also eliminated to adapt the glass pane insert to a specific door leaf profile defined by its width measured perpendicular to the leaf plane.

[0028] A further advantage of the door leaf according to the invention is that profile half-shells can be combined as required, as required by the customer. For example, the two profile half-shells can have different colors.

[0029] For the assembly of the door leaf profile, it is particularly conceivable and preferred that the first profile half-shell is assembled first, with the individual profile parts of the first profile half-shell being connected to one another, in particular screwed or welded together. Individual web parts of the insulating web are attached to the individual profile parts of the first profile half-shell and firmly connected to the profile parts. In particular, individual web parts of the insulating web, which is formed from the sum of all its web parts, can be rolled onto respective associated profile parts of the first profile half-shell, whereby a positive connection is formed between a respective web part of the insulating web and an associated profile part of the first profile half-shell.The individual web parts can, for example, and preferably, be elongated, wherein the lengths of the web parts are preferably adapted to the lengths of the associated profile parts of the first profile half-shell such that the web parts extend at least substantially over the entire length of the respective associated profile part. The connection of the individual web parts of the insulating web to the individual profile parts of the first profile half-shell preferably takes place before the connection of the individual profile parts to form the first profile half-shell.

[0030] The adhesive is applied along the edging strip of the first profile half-shell either before or after the profile half-shell is connected to the insulating strip. As described separately below, this adhesive is formed at least partially, preferably completely, by a double-sided adhesive tape. Preferably, the adhesive is still protected on the side facing the sash filling at this time, so that the first profile half-shell with its edging strip can be placed on the edge region of the first outer surface of the sash filling without the adhesive bond to the sash filling being activated. The first profile half-shell is then aligned to the sash filling as desired. The sash filling is preferably arranged flat on a substrate so that the outer surfaces of the sash filling are oriented horizontally.The first profile half-shell is guided from above onto the upwardly directed first outer surface of the sash filling, so that the first profile half-shell with its edging strip and the adhesive attached to it rests from above on the outer edge area of ​​the upwardly directed first outer surface of the sash filling.

[0031] The bond is then released, whereby, for example, a protective strip of the bond or double-sided adhesive tape facing the sash filling can be removed so that an adhesive surface of the bond comes into direct contact with the first outer surface of the sash filling, thus creating the desired material-to-material connection between the sash filling and the first profile half-shell. The sash filling, together with the attached first profile half-shell and the insulating bar connected to the latter, is then rotated 180° around the horizontal axis so that the sash filling is once again aligned horizontally and the second outer surface of the sash filling is aligned upwards and exposed. The second profile half-shell is then attached to the second outer surface.

[0032] For this purpose, the second profile half-shell is also placed on the sash filling. In this case, it is conceivable to either place the individual profile parts of the second profile half-shell individually and bring them into direct and / or indirect engagement with the insulating strip or - similar to the first profile half-shell - to first connect the profile parts of the second profile half-shell together and then place the second profile half-shell as a whole on the sash filling. Before placement, the adhesive is applied to the edging strip of the second profile half-shell, similar to the first profile half-shell. Placing the second profile half-shell on the sash filling then consists in bringing the edging strip of the second profile half-shell into contact with the edge region of the second outer surface of the sash filling, with the adhesive being arranged between the edging strip and the edge region of the sash filling.Here, too, the bond can be "activated" as needed, for example, by peeling off a protective strip from the bond, exposing its adhesive surface. During this process, the second profile half-shell comes into direct and / or indirect contact with the insulating strip.

[0033] The special feature of the door leaf is that the second profile half-shell can be moved towards the first profile half-shell, i.e. in a direction perpendicular to the outer surfaces of the leaf filling (and therefore perpendicular to the leaf plane of the door leaf), and the engagement with the insulating bar can be established until the edging strip of the second profile half-shell lies almost flush with the second outer surface of the leaf filling. The engagement of the second profile half-shell with the insulating bar is in particular not tied to a defined relative position of the insulating bar and the second profile half-shell in a direction perpendicular to the leaf plane, for example in order to achieve a positive connection in this direction, but is, on the other hand, at least essentially, preferably completely, continuously possible. In other words, the second profile half-shell and the insulating bar (orThe two profile half-shells (the two profile half-shells) can be "pushed together" as needed until the desired, almost flush fit of the edging strips of the two profile half-shells is achieved against both outer surfaces of the sash infill. A defined relative position of the two profile half-shells to each other in a direction perpendicular to the outer surfaces of the sash infill or perpendicular to the sash plane, which the profile half-shells must necessarily achieve to achieve a specific function, such as locking, does not exist. The only decisive factor is that the second profile half-shell and the insulating bar engage with each other directly and / or indirectly, and that the adhesive bonds of the two profile half-shells are in contact with the corresponding outer surfaces of the sash infill and are activated.The two profile half-shells are then fixed relative to each other due to their bonding to the sash filling, although as such they are not directly firmly connected to each other when viewed in the direction perpendicular to the sash plane.

[0034] In contrast to this approach, the prior art provides for the formation of a positive fit that locks the profile half-shells relative to one another in a direction perpendicular to the leaf plane. Typically, a distance between the profile half-shells is set to a specific value for design reasons (namely to achieve the positive fit), for example to activate a latch or the like. Therefore, in the prior art, it is not the door leaf profile that is adapted to the respective leaf filling, but conversely the leaf filling is adapted to the respective door leaf profile by means of compensating elements. Conversely, according to the invention, the door leaf profile is adapted to the leaf filling in a direction perpendicular to the leaf plane.This enables an almost flush installation of the sash filling into the door leaf profile, i.e. preferably with the minimal offset described above between the outer surfaces of the sash filling and the associated outer surfaces of the door leaf profile.

[0035] The force-transmitting connection between the two profile half-shells in the direction perpendicular to the leaf plane, which in the prior art is ensured by a corresponding positive fit, is achieved in the present door leaf by bonding the profile half-shells to the leaf panel along the edging strips. This ensures that, on the one hand, the door leaf profile is firmly connected to the leaf panel in the fully assembled state of the door leaf, and, on the other hand, the two profile half-shells are indirectly secured relative to each other in the direction perpendicular to the leaf plane by means of the bonding via the leaf panel.

[0036] Accordingly, it is not necessary to have different door leaf profiles available for different leaf fillings, especially those with different thicknesses, since the profile half-shells of the door leaf profile of the door leaf according to the invention can be moved towards each other as needed during assembly, thereby forming the indirect and / or direct engagement of the second profile half-shell with the insulating strip, so that the door leaf profile adapts to the thickness of the respective leaf filling. This always achieves the desired, almost flush connection of the door leaf profile to the leaf filling on both sides.

[0037] Thus, the two profile half-shells of a first door leaf profile, when interacting with a first leaf filling which has a first thickness, are arranged at a first distance from one another measured perpendicular to the leaf plane, while the two profile half-shells of a second door leaf profile, when interacting with a second leaf filling which has a second thickness which is greater in magnitude than the first thickness of the first leaf filling, are arranged at a second distance from one another measured perpendicular to the leaf plane, wherein the second distance is greater in magnitude than the first distance.In both cases, the edging strips of the profile half-shells, which are identical in both door leaf profiles, are almost flush with the corresponding outer surfaces of the respective leaf panel. A connection exists between the two profile half-shells, at least via the insulating strip, and possibly also via at least one other component (e.g., a connecting device). Likewise, a connection exists between the two profile half-shells via the adhesive joints across the leaf panel.When using the second wing panel with a greater thickness than the first wing panel, the profile half-shells are simply pushed closer together without impairing the function of the door panel profile, as long as—this is a prerequisite—the second profile half-shell engages directly and / or indirectly with the insulating bar, and thus, via the insulating bar, the second profile half-shell engages with the first profile half-shell. A difference in the thicknesses of the wing panels can also occur in the form of manufacturing-related tolerances. Such tolerances are unproblematic with the door panel according to the invention for the reasons stated.

[0038] In particular, it is not the case that the two profile half-shells must be arranged at a fixed distance from each other, measured perpendicular to the sash plane, or are intended to be arranged at a fixed distance in order to function technically. This is the case in the prior art, whereby, in order to adapt to sash fillings of different thicknesses, the offset between a respective outer surface of the sash filling and the corresponding outer surface of the respective profile half-shell must be compensated for using a compensating element, such as a so-called "glazing rubber." For a "thick" sash filling, this offset is smaller in the prior art than for a "thin" sash filling, since the outer surfaces of the profile half-shells are arranged at a fixed distance from each other and cannot be adapted to the respective sash filling.Particularly in the case of door leaves formed by sliding door leaves, the DIN EN 16005 standard, which is currently applicable in Europe on the date of filing this application, is of great relevance. It defines a maximum permissible distance between a fixed protective device and the leaf filling, whereby this distance is measured in a direction perpendicular to the leaf plane from a surface of the protective device facing the door leaf to the outer surface of the leaf filling facing the protective device.If a leaf panel is relatively "thin" or fails, the known "rigid" door panel profiles, whose profile half-shells cannot be adjusted in their spacing from one another as in the present invention, inevitably result in a larger distance between the protective device and the leaf panel, since the leaf panel must, in a sense, move away from the protective device (compensated against the corresponding profile half-shell by means of a glazing rubber). This can lead to the permissible distance value (currently 8 mm) being exceeded and the door system therefore no longer meeting the specified standard. The invention solves this problem because the profile half-shells adapt to the "thin" leaf panel, thus eliminating the need for the leaf panel to "move away" from the protective device. Instead, the distance from the protective device remains the same as it would be if the leaf panel were thicker.The maximum permissible distance can therefore be reliably maintained, regardless of the sash filling, for example due to manufacturing tolerances.

[0039] The non-positive engagement of the second profile half-shell with the insulating web in the direction perpendicular to the sash plane can be realized, for example, and preferably, by a tongue-and-groove connection. In this case, it is particularly conceivable for the insulating web to have at least one, preferably several, groove-shaped profile sections facing the second profile half-shell, which are suitable for receiving complementary tongue-shaped profile sections of the connecting device. A corresponding design is explained separately below. A tongue-and-groove connection has the particular advantage of enabling a continuous "pushing together" of the components involved, in that the respective tongue-shaped component only penetrates into the corresponding groove-shaped component as far as the respective installation situation allows and requires. A positive connection between the tongue and groove in the direction of "pushing together" (perpendicular to the sash plane) does not occur.Accordingly, the groove-shaped and tongue-shaped profile sections are preferably aligned perpendicular to the leaf plane of the door leaf.

[0040] In a preferred embodiment of the door leaf, the engagement between the second profile half-shell and the insulating web is designed to be free of constraints, in particular completely form-fitting, parallel to the respective profile longitudinal axes of mutually associated profile parts of the profile half-shells and web parts of the insulating web. "Free of constraints" in this context means that the second profile half-shell and the insulating web can move relative to each other in a direction parallel to the respective profile longitudinal axis without forming a constraint between two points spaced apart along a respective profile longitudinal axis. Such a constraint-free connection exists in particular when the second profile half-shell and the insulating web are connected to each other in a direction parallel to the respective profile longitudinal axis without a form-fitting connection, since in this way, no constraint (and thus, in particular, constraint stresses) can occur along the profile longitudinal axes.If length differences occur, the respective components can instead move relative to one another. As an alternative to such a preferred non-positive connection, it is also conceivable for the second profile half-shell and the insulating web to be connected to one another at only one point, for example centrally along a length of the respective profile part of the second profile half-shell. Such a connection can, for example, be in the form of a screwed-in screw that positively connects the respective profile part of the second profile half-shell to the associated web part of the insulating web. However, since this connection only exists at one point, no constraints arise between the respective profile part and the associated web part as soon as length differences arise, for example as a result of temperature differences.The exemplary embodiment with a connection at one point is therefore not form-fitting in the direction parallel to the respective profile longitudinal axis of the respective profile part of the second profile half-shell, but is free of constraints within the meaning of the present application.

[0041] This design has the particular advantage that the mutually associated profile parts of the profile half-shells can move relative to one another (via the insulating web) in a direction parallel to their respective longitudinal profile axes. This can be particularly advantageous when temperature differences occur between the two profile half-shells in order to prevent deformation of the door leaf. In an exemplary design, mutually associated horizontal profile parts of both profile half-shells can engage with one another via the insulating web and, if appropriate, a further component (e.g., a connecting device), wherein the engagement is designed to be form-fitting in a direction perpendicular to the leaf plane (see above) and, moreover, is designed to be form-fitting parallel to the longitudinal profile axes of the horizontal profile parts (i.e., the respective longitudinal profile directions). The same is also conceivable for vertically oriented profile parts.

[0042] In this way, the profile parts are not only movable relative to one another in a direction perpendicular to the leaf plane, but also in a direction parallel to their respective longitudinal profile axes. This has the particular advantage that the mutually assigned profile parts of the profile half-shells - and thus the profile half-shells as such - can move relative to one another at least to a small extent, in particular in order to absorb deformations resulting from a temperature gradient between the two sides of the door leaf. This can prevent the door leaf profile and the door leaf as a whole from deforming when temperature differences occur between the temperatures occurring on the two sides of the door leaf. Instead, the profile parts of the profile half-shells (or the profile half-shells) can move when such temperature differences occur.the profile parts of the second profile half-shell and the associated web parts of the insulating web) move against each other in a respective longitudinal direction of the profile and thereby compensate for the differences in the dimensions of the profile parts of the two profile half-shells caused by temperature differences. In this case, it can also be harmless if the indirect and / or direct engagement between the second profile half-shell and the insulating web is designed to form a frictional connection, for example as a result of the design of a press fit. Since the forces that act between the two sides of the door leaf, in particular when temperature differences occur, can reach considerable levels, any static friction between the insulating web and the component engaging with the insulating web is overcome, so that the relative movement of the respective profile parts can take place in a direction parallel to their longitudinal profile axes.

[0043] Furthermore, a design of the door leaf may be advantageous in which the engagement between the second profile half-shell and the insulating web is formed in a direction oriented perpendicular to the respective longitudinal profile axes of the profile parts of the profile half-shells and parallel to the leaf plane, forming a positive connection. In other words, the indirect and / or direct engagement of the second profile half-shell with the insulating web is preferably designed such that a positive connection is formed in a direction parallel to the leaf plane and perpendicular to the longitudinal profile axes of the respective profile parts.In particular and preferably, the respective components involved, that is to say on the one hand the insulating web and on the other hand, for example, directly the second profile half-shell or, for example, a connecting device, can overlap in a direction perpendicular to the profile longitudinal axes and parallel to the sash profile, so that a relative movement of the two profile half-shells in a direction parallel to the sash plane and perpendicular to the profile longitudinal axes of the respective profile parts is blocked.

[0044] In this way, a force oriented parallel to the leaf plane and perpendicular to the profile longitudinal axes can be transmitted between the profile half-shells, even if the profile half-shells are not bonded to the leaf panel by means of adhesives. This design has the particular advantage that forces oriented in this way, i.e., forces oriented parallel to the leaf plane and perpendicular to the profile longitudinal axes, can be applied to the door leaf profile and distributed along the door leaf profile, so that the force flow via the adhesives into the leaf panel is evenly distributed across the adhesives.If, for example, the door leaf is designed in the form of a sliding door leaf, it is conceivable that the leaf profile is suspended in a guide rail at an upper end of the door leaf, so that the dead weight of the door leaf is transferred into the guide rail via the upper profile parts of the profile half-shells. The weight of the door leaf is a force of this kind, which is oriented parallel to the leaf plane and perpendicular to the longitudinal profile axes of the upper, horizontally oriented profile parts of the profile half-shells. This force can therefore be distributed in the upper section of the door leaf profile between the horizontally oriented profile parts of the profile half-shells due to the positive connection formed in this direction and, in particular, does not act exclusively on just one of the profile parts or just one of the two profile half-shells.

[0045] As already indicated above, it can also be particularly advantageous if the second profile half-shell and the insulating bar are directly and / or indirectly engaged with one another in such a way that they form a frictional connection with one another at least in the direction perpendicular to the leaf plane. This frictional connection does not fundamentally prevent relative movement of the profile half-shells in the direction perpendicular to the leaf plane. However, it does allow a clean joining of the second profile half-shell relative to the first profile half-shell. With regard to the advantageous method for assembling the door leaf described above, for example, the second profile half-shell is brought into direct and / or indirect engagement with the insulating bar when it is placed on the leaf filling.The frictional engagement described offers a certain resistance during assembly and thus the possibility of exact alignment of the respective profile parts of the second profile half-shell, before the respective profile part is then deliberately "pushed in" by applying an assembly force in a direction perpendicular to the outer surfaces of the sash filling, thereby obtaining a secure fit relative to the first profile half-shell for assembly purposes.

[0046] To create the frictional connection, it can be provided, for example, that a tongue-shaped profile section of one component, for example a connecting element of a connecting device, is designed with a certain excess compared to a complementary groove-shaped profile section of the other component, for example the insulating web, so that the tongue is inserted into the associated groove only after and by overcoming a certain resistance. Such a frictional connection - in contrast to a positive connection - can nevertheless be released non-destructively in a direction perpendicular to the outer surfaces of the sash filling or perpendicular to the sash plane by overcoming the frictional connection acting between the respective components or the resulting static friction. This relative movement of the two profile half-shells to one another is prevented only by the adhesive bond to the sash filling.

[0047] In a particularly preferred embodiment of the door leaf, the door leaf profile comprises a connecting device that is firmly connected to the second profile half-shell and arranged, at least in sections, on at least some of the profile parts of the second profile half-shell. The connecting device is intended and configured to at least partially establish the engagement of the second profile half-shell with the insulating web. Thus, when using such a connecting device, the engagement of the second profile half-shell with the insulating web is at least also "indirect" within the meaning of the present application.In this case, it is fundamentally conceivable that a connecting device is used only in sections, whereby, for example, horizontally oriented profile parts of the second profile half-shell engage with the insulating web indirectly, namely by means of the connecting device, while vertically oriented profile parts of the second profile half-shell engage with the insulating web directly, i.e., without a connecting device. Other combinations are of course also conceivable. Nevertheless, it is preferred that the engagement between the second profile half-shell and the insulating web along all profile parts of the second profile half-shell occurs either indirectly (in particular by means of a mentioned connecting device) or directly.

[0048] Furthermore, it is conceivable that an engagement along a respective profile part of the second profile half-shell with the insulating web exists both indirectly and directly, wherein, for example, at a first point of the profile part, a connecting device is placed between the profile part and the associated web part of the insulating web (indirect engagement) and at another point the profile part and the web part of the insulating web are in direct contact with each other (direct engagement).

[0049] The use of a connecting device generally has the advantage that the thermal transmittance of the door leaf profile can be improved. In particular, the distance between the profile half-shells, measured perpendicular to the leaf plane, can be increased because, when using the connecting device, the second profile half-shell does not have to engage with the insulating bar, for example by retracting into it, but the connecting device does this. Therefore, the second profile half-shell can, for example, end outside the insulating bar (i.e., remain without direct contact with the insulating bar) and thus remain at a greater distance from the first profile half-shell. This has a positive effect on the thermal transmittance of the door leaf profile. This applies in particular when the connecting device is made of plastic. This configuration is accordingly preferred.

[0050] In a preferred embodiment, the connecting device itself comprises an insulating web, which is referred to as a "second insulating web" within the meaning of the present application. If the connecting device comprises such a second insulating web, the insulating web connected to the first profile half-shell is referred to as the "first insulating web" within the meaning of the present application. The second insulating web is firmly connected to the second profile half-shell, whereby the second insulating web can be connected to the second profile half-shell, for example and preferably by forming a positive connection. For example, the second insulating web can engage a complementarily shaped undercut of the second profile half-shell by means of a dovetail-shaped section.In this embodiment, the first insulating web, which is firmly connected to the first profile half-shell, and the second insulating web are at least also in direct engagement with one another when the door leaf profile or the door leaf is assembled. The second insulating web - just like the first insulating web independently - is preferably formed from individual elongated web parts, which can in particular be formed from extruded plastic profiles. Preferably, each profile part of the second profile half-shell is assigned exactly one web part of the second insulating web, wherein the web parts of the insulating web preferably extend at least substantially over the entire length of the respectively associated profile part of the second profile half-shell.

[0051] Preferably, the two insulating bars can together form a tongue and groove connection that is aligned perpendicular to the leaf plane of the door leaf. In this way, during assembly of the door leaf profile, at least one tongue-shaped profile section of one insulating bar can engage a complementary groove-shaped profile section of the other insulating bar in a direction perpendicular to the leaf plane. The two profile sections form a positive connection in a direction parallel to the leaf plane and perpendicular to the profile longitudinal axes of the respective profile parts. However, a positive connection in a direction perpendicular to the leaf plane is not desired, so that during assembly of the door leaf the two insulating bars can be pushed together in a direction perpendicular to the leaf plane until the door leaf profile is almost flush with the leaf filling, as desired.Furthermore, such a tongue-and-groove connection has the advantage that the two insulating webs remain movable relative to each other in a direction parallel to the longitudinal axes of the corresponding profile parts of the profile half-shells, so that the two profile half-shells effectively have a corresponding degree of freedom. In this direction, the connection between a respective web part of the first insulating web and a respective web part of the second insulating web also remains non-positively locked.

[0052] In a further advantageous embodiment of the door leaf, the connecting device can comprise a plurality of, preferably identical, connecting elements. The connecting elements are preferably made of plastic. The connecting elements are distributed along respective longitudinal profile axes of at least some of the profile parts, preferably along the longitudinal profile axes of all profile parts, of the second profile half-shell and are connected to the second profile half-shell. The distribution of the connecting elements can, in particular, be equidistant. In this embodiment, the connecting elements of the connecting device engage directly with the insulating web firmly connected to the first profile half-shell.In principle, a connecting device is conceivable that comprises a combination of a second insulating web and a plurality of individual connecting elements, wherein, for example, individual profile parts of the second profile half-shell interact with web parts of a second insulating web, and other profile parts of the second profile half-shell each interact with several individual connecting elements distributed along the respective profile longitudinal axis. Nevertheless, it is advantageous if the connecting device comprises either individual connecting elements or a second insulating web.

[0053] The individual connecting elements can, for example, and preferably, be formed by individual clips that are connected to the second profile half-shell, in particular, are "clipped" onto it in a form-fitting manner. It is also conceivable for the connecting elements to be connected to the second profile half-shell by means of a clamping or expanding connection. It is advantageous if the connecting device comprises so many connecting elements that they are distributed along the longitudinal axis of a respective profile part of the second profile half-shell. Preferably, at least 5, preferably at least 10, more preferably at least 15 individual connecting elements are assigned to at least one of the profile parts of the second profile half-shell. This preferably applies to all profile parts of the second profile half-shell. The connecting elements are preferably distributed equidistantly along the respective profile part.

[0054] The individual connecting elements are preferably designed in such a way that they are particularly well suited to forming a frictional connection with the insulating strip in a direction perpendicular to the sash plane. For this purpose, it is advantageous if the connecting elements are designed to enter a groove-shaped profile section of the insulating strip, wherein the connecting elements are manufactured with an oversize relative to the groove-shaped profile section. For example, and preferably, the connecting elements can each have an internal cavity that allows them to be "compressed" when inserted into the groove-shaped profile section of the insulating strip, whereby the cavity is at least partially overpressed. Restoring forces thus formed in the connecting elements cause a frictional connection with the groove-shaped profile section of the insulating strip.Such a design of the connecting elements can also be seen in one of the embodiments below.

[0055] The design of the connecting device with a plurality of individual connecting elements has the advantage that the joining of the connecting device with the insulating strip, which is firmly connected to the first profile half-shell, can be influenced. In particular, the frictional engagement with the insulating strip can be "adjusted" by the number of connecting elements used, with a larger number of connecting elements causing a greater degree of frictional engagement than a smaller number. In addition, the connecting elements are particularly easy to mount on the profile parts of the second profile half-shell, so that the assembly effort for installing the door leaf profile is minimal. Furthermore, the contact between the two profile half-shells can generally be reduced to individual connection points, namely the points where the connecting elements engage with the first insulating strip.Only at these points is heat conduction from one of the two profile halves to the other possible. Heat conduction through the door leaf profile is therefore significantly reduced.

[0056] The adhesive bonds for bonding the edging strips of the profile half-shells to the sash infill each comprise at least one double-sided adhesive tape. Preferably, the bonds are formed entirely from double-sided adhesive tape. This design has the particular advantage that the bonds are particularly easy to handle. Protective strips can remain on the adhesive tape, particularly during installation, and can be removed as needed to expose a particular bonding surface. From a mechanical perspective, i.e., measured by its ability to reliably transmit occurring forces without bond failure, the bond created by the bonds can easily be provided by double-sided adhesive tape. Products that demonstrate appropriate suitability are well-known and available on the market.In the double-sided adhesive tape design, a section of the double-sided adhesive tape can be applied particularly easily to the respective section of the edging strip for each of the individual profile parts of the profile half-shells, along the entire length of the respective profile part. The adhesive tape can be particularly easily adjusted to the length of the respective associated profile part. A further advantage of the double-sided adhesive tape is that it is applied particularly thinly, so that the previously described flush surface between the respective outer surface of the sash infill and the respective associated edging strip of the respective profile half-shell is not compromised.

[0057] With regard to the formation of the bonds of double-sided adhesive tape, it can also be particularly advantageous if the adhesive tape has a base body formed from an elastomer. This design has the particular advantage that the adhesive tape as such can absorb a certain shear deformation in a direction parallel to an adhesive surface of the adhesive tape. This is particularly advantageous with regard to possible deformations of the door leaf profile and / or the leaf filling due to temperature differences between the two sides of the door leaf. This has already been explained above in connection with an advantageous mobility of mutually assigned profile parts of the two profile half-shells relative to one another, parallel to the longitudinal axis. With regard to the connection of the profile half-shells to the leaf filling via the bonds, such mobility can also be particularly advantageous in the area of ​​the bonds.To compensate for temperature-related deformations, only very small movements are required, which can be easily absorbed by an adhesive tape whose base is made of an elastomer. Such movements can occur, for example, in the range of approximately 1 mm / m, and in extreme cases even more. This is especially true when the profile parts of the profile half-shells are made of aluminum, so that temperature differences between the inside and outside of the profile parts result in different lengths of the profile parts of the two profile half-shells due to the material.

[0058] With regard to the door leaf profile as such, a door leaf whose profile half-shells are designed with a matching number and orientation of the respectively associated profile parts can be particularly advantageous. The profile half-shells preferably each comprise two horizontally oriented profile parts for enclosing an upper horizontal edge region and a lower horizontal edge region of the outer surfaces of the leaf panel. Furthermore, the two profile half-shells preferably each comprise at least one vertical profile part for enclosing a lateral edge region of a respective outer surface of the leaf panel. With such a configuration, the leaf panel would be enclosed along three sides by the door leaf profile, namely along its two horizontal edges and along one vertical edge.

[0059] However, a particularly preferred embodiment is one in which the door leaf profile surrounds the leaf panel in a frame-like manner, so that all edges of the leaf panel are enclosed by the door leaf profile. In this case, it is preferable if the profile half-shells each have four profile parts, with two profile parts being formed by vertical profile parts and two profile parts being formed by horizontal profile parts. The horizontal profile parts and the vertical profile parts of at least one profile half-shell are preferably connected to one another to form a (half-)frame and thus constitute the respective profile half-shell.

[0060] In a further advantageous embodiment, the insulating web firmly connected to the first profile half-shell can be formed from a number of individual web parts corresponding to the number of profile parts of the first profile half-shell. In this case, a web part of the insulating web is assigned to each of the profile parts of the first profile half-shell. The respective web parts preferably extend completely along the assigned profile parts, so that the insulating web is arranged completely on the first profile half-shell. In particular, the insulating web can have at least one vertically oriented web part and at least one horizontally oriented web part, corresponding to the first profile half-shell. The web parts preferably each extend at least substantially over the entire length of the respectively associated profile part of the first profile half-shell.

[0061] Furthermore, a design of the door leaf can be advantageous in which the profile parts of the profile half-shells are made of aluminum, in particular in the form of extruded aluminum profiles, or plastic, in particular in the form of extruded plastic profiles. In particular, the profile parts of the profile half-shells can be produced using the extrusion process (aluminum) or by extrusion (plastic). The insulating bar can in particular be produced by extrusion, i.e. the individual bar parts of the insulating bar are preferably formed from extruded plastic profiles. The plastic design of the insulating bar ensures low heat transfer between the two profile half-shells. The latter can in particular be made of aluminum, which offers both good robustness and a pleasant material appearance.

[0062] If the leaf filling is formed by a glass pane insert, it is preferred if the glass pane insert is formed from a plurality of individual, flat, planar glass panes arranged in a row next to one another and at a distance from one another. These are connected to form a coherent glass pane package, for example and preferably in the form of double-pane insulating glazing or triple-pane insulating glazing. The glass panes are arranged parallel to one another and typically each have the same size. The glass panes are aligned relative to one another around the edges by means of spacers and are glued to one another via the spacers and sealed at their edge-side end faces, so that the glass panes together form the glass pane insert in the form of the glass pane package. This is accordingly preferably an assembled component that is accommodated as a whole in the door leaf profile.The spaces between the individual glass panes are preferably filled with a gas, such as air, argon, or krypton. The glass panes can preferably be coated with a heat-insulating coating to reduce losses from thermal radiation.

[0063] The underlying object is further achieved by means of a system having the features of claim 13. The system comprises a plurality of door leaves according to the present invention, wherein the door leaves can advantageously be designed according to the above description.

[0064] The system is characterized in that the profile half-shells and the insulating web of the door leaf profile of a first door leaf of the system are each identical to the profile half-shells and the insulating web of the door leaf profile of a second door leaf of the system. In contrast to the door leaf profiles, however, the leaf fillings of the two door leaves are designed differently, with the leaf fillings differing from one another in particular in their thickness measured perpendicular to the leaf plane. Consequently, the leaf filling of the first door leaf is thicker than the leaf filling of the second door leaf. Despite this difference in the thicknesses of the leaf fillings, according to the invention both the leaf filling and the door leaf profile of the first door leaf and the leaf filling and the door leaf profile of the second door leaf are designed to be almost flush on both sides of the respective door leaf.This means that for both door leaves, a respective offset, measured perpendicular to the leaf plane, between a respective outer surface of the respective leaf panel and an outer surface of the profile half-shell of the door leaf profile associated with the outer surface corresponds to the sum of the thickness of the bond and the thickness of a profile section of the respective profile part of the respective profile half-shell forming the respective edging strip. This sum is preferably at most 8 mm, preferably at most 4 mm, more preferably at most 3 mm.

[0065] In other words, an overlap dimension measured perpendicular to the leaf plane, by which the insulating strip and the second profile half-shell of the door leaf profile of the first door leaf maximally overlap, directly and / or indirectly in a direction perpendicular to the leaf plane, is smaller than a correspondingly measured overlap dimension by which the insulating strip and the associated second profile half-shell of the door leaf profile of the second door leaf maximally overlap, directly and / or indirectly perpendicular to the leaf plane. The "overlap" can, in particular, take the form of a tongue-shaped profile section inserted into a groove-shaped profile section.

[0066] The system according to the invention therefore has the advantage that, regardless of the leaf filling, the same door leaf profile can always be used for different door leaves, yet a virtually flush finish can still be achieved between the leaf filling and the profile half-shells on both sides of the door leaf. Depending on the thickness of the respective leaf filling, the two profile half-shells are moved towards each other to different extents during the assembly of the door leaf, i.e., the indirect and / or direct engagement between the second profile half-shell and the insulating strip is formed to different "depths." According to the above description, this engagement is preferably stepless, so that it can always be formed until the desired virtually flush finish is achieved. Therefore, the system eliminates the need for different door leaf profiles with different profile half-shells for different leaf fillings.

[0067] As already explained above, the door leaf according to the invention can be used particularly advantageously for a sliding door leaf of an automatic sliding door. Accordingly, an automatic sliding door is particularly advantageous which comprises at least one sliding door leaf formed by a door leaf according to the present invention. As further components, the automatic sliding door can furthermore comprise, in a manner known per se, a control system, at least one drive for moving the sliding door leaf, and at least one presence sensor for monitoring at least one side of the automatic sliding door. The underlying object is therefore further achieved by means of an automatic sliding door with the features of claim 14.

[0068] When designing the door leaf as a sliding door leaf, it can be particularly advantageous if the door leaf has at least one sealing contour, preferably at least two sealing contours, on an end face of a vertically oriented profile section of the door leaf profile facing away from the leaf panel, which sealing contours extend in the vertical direction along the respective profile section of the door leaf profile at least substantially over the entire height of the door leaf. The at least one sealing contour is provided and configured to interact with a complementarily designed sealing contour, so that at least when the automatic sliding door is in a closed state, there is a tight connection between the door leaf and a respective further component on which the complementary sealing contour is arranged.

[0069] In a particularly preferred embodiment, the automatic sliding door comprises a total of two sliding door leaves, each formed by a door leaf according to the present invention. It is particularly advantageous if the two door leaves have complementary sealing contours on their mutually facing profile sections of their respective door leaf profiles, which are provided and configured to cooperate sealingly when the automatic sliding door is in a closed state. The resulting seal is at least substantially windproof and rainproof.

[0070] In this case, it can be particularly advantageous if each sealing contour is formed from an extruded plastic, in particular an elastomer. Complementary sealing contours are preferably designed in the manner of a tongue-and-groove system, so that a groove-shaped sealing contour of one door leaf can engage a tongue-shaped sealing contour of the other door leaf, thereby creating a sealed connection.

[0071] The underlying object is further achieved by means of a method for producing a door leaf with the features of claim 15. Advantageous embodiments emerge from the associated subclaim as well as the description and the exemplary embodiments.

[0072] The method provides that two profile half-shells forming a door leaf profile are moved towards each other in a direction perpendicular to a leaf plane of the door leaf until they come into contact with respective edging strips with the interposition of an adhesive on opposite outer surfaces of a leaf filling and are glued to the leaf filling, wherein in the course of the movement of the two profile half-shells towards each other the second profile half-shell engages indirectly and / or directly with an insulating web fixedly arranged on the first profile half-shell, preferably in a stepless, form-fitting manner.

[0073] The method according to the invention is particularly well suited for producing a door leaf according to the invention or one described as advantageous according to this application. The resulting advantages have already been described above. Examples of implementation

[0074] The invention is explained in more detail below using an exemplary embodiment illustrated in the figures. It shows: Fig. 1: A cross section through a first door leaf according to the invention, Fig. 2: A cross section through a second door leaf according to the invention, Fig. 3: The cross section according to Figure 2 in a different perspective, Fig. 4: A cross section through a third door leaf according to the invention, Fig. 5: A cross section through a door leaf profile of a door leaf according to the invention, Fig. 6: A cross section through a fourth door leaf according to the invention.

[0075] A first embodiment, which is Figure 1 shown, describes a door leaf according to the invention 1, the one wing filling 2 and a door leaf profile 4 The wing filling 2 is here and preferably formed by a glass pane insert, which is described in more detail below. The door leaf profile 4In the example shown, it is frame-like and almost the wing filling 2 all around the edge. The door leaf profile 4 includes two profile half shells 7, 8 and an insulating bar 9. The profile half shells 7, 8 are each one of two outer surfaces 5, 6 the wing filling 2 assigned, whereby the first outer surface 5 a first side of the door leaf 1 and the second outer surface 6 the second side of the door leaf 1 The two outer surfaces 5, 6 thus form opposite sides of the wing filling 2.

[0076] The latter is flat and in the example shown comprises a total of three glass panes 19, which are arranged at a distance from each other and parallel to each other. Thus, the wing filling 2here and preferably formed by triple-glazed insulating glass. Overall, a perpendicular to a sash plane 3 of the door leaf 1 measured thickness 25 the wing filling 2 significantly smaller than a length and a height of the wing filling 2. The glass panes 19 the wing filling 2 are arranged in a row at a distance from each other and are firmly connected to each other via connecting elements and sealed against each other all the way around the edges, so that the sash filling 2 forms a coherent component. Therefore, the wing filling 2 rigid in itself, so that a perpendicular to the wing plane 3 measured distance between its two outer surfaces 5, 6, the fat one 25 the wing filling 2 cannot be altered as intended. The gaps between the glass panes 19are here and preferably filled with a gas, for example argon, so that the glass pane insert has the best possible heat transfer coefficient.

[0077] The two profile half shells 7, 8 are each one of the outer surfaces 5, 6 assigned. The profile half-shells 7, 8 each have a border strip 14, 15 on, whereby the edging strips 14, 15 are intended and equipped for this purpose, with assigned peripheral areas 12, 13 the exterior surfaces 5, 6 the wing filling 2 The frame of the wing filling 2 using the door leaf profile 4 is by means of the edging strips 14, 15 manufactured, which fills the wing 2 edge-side in a direction perpendicular to the wing plane 3 Here, the profile half-shells 7, 8 with their edging strips 14, 15 laterally against the edge areas 12, 13the exterior surfaces 5, 6 the wing filling 2 This is done by interposing an adhesive bond 20, which will be discussed separately below. In this way, the wing filling 2 in the direction perpendicular to the wing plane 3 form-fitting between the two profile half-shells 7, 8 stored.

[0078] The profile half shells 7, 8 are each made up of a plurality of profile parts 21, 22 formed, whereby in the example shown both profile half-shells 7, 8 are designed like a frame and each has a total of four profile parts 21, 22 namely two horizontally oriented profile parts 22 and two vertically oriented profile parts 21. The profile parts 21, 22can in particular be formed by elongated hollow chamber profiles, as can be seen in the figures. In the example shown, the profile parts 21, 22 each made of aluminum, with the profile parts 21, 22 were manufactured using the extrusion process and are each a single piece. The individual profile parts 21, 22 of the two half shells 7, 8 can be connected to each other, for example screwed together. This is preferred at least for the first profile half-shell 7 the case, so that the latter forms a coherent frame for the first outer surface 5 the wing filling 2 forms.

[0079] The insulating bridge 9 of the door leaf profile 4 is between the two profile half shells 7, 8 arranged and each with a peripheral end face 11 the wing filling 2In the example shown, the insulating bar is 9 circumferentially on the front surface 11 the wing filling 2 arranged because the door leaf profile 4 overall frame-like the wing filling 2 The insulating bar 9 In the example shown, it is made of plastic, with individual web parts 23, 24 the insulating bar 9 are formed by elongated, extruded profiles, each of which is made in one piece. The insulating bar 9 is fixed to the first profile half shell 7 connected, whereby in the example shown the insulating bar 9 and the first profile half shell 7 are connected to each other to form a positive connection. For this purpose, the insulating bar 9 on its bridge parts 23, 24 dovetail-shaped profile sections, which fit positively into complementary undercuts of the first profile half-shell7 In the example shown, each of the profile parts 21, 22 the first profile half-shell 7 exactly one web part each 23, 24 the insulating bar 9 assigned, whereby the insulating bar 9 corresponding to a total of two vertical web parts 23 and two horizontal web parts 24 The bridge parts 23, 24 extend parallel to the respective assigned profile part 21, 22. The insulating bridge 9 serves to connect the two profile half shells 7, 8 thermally separated from each other and thus a low heat transfer coefficient of the door leaf profile 4 The bridge parts 23, 24 each extend at least substantially along the entire length of the respective associated profile part 21, 22.

[0080] In the Figure 1 In the example shown, the second profile half-shell 8with a connecting device 10 together, which here a variety of connecting elements 28 The connecting elements 28 are each separately spaced from each other, preferably equidistant, along the profile parts 21, 22 the second profile half shell 8 distributed, whereby in the example shown they are arranged perpendicular to the wing plane 3 protruding webs 26 the second profile half shell 8 are connected. The connecting elements 28 are each made of plastic and are form-fitting to the second profile half-shell 8 or their profile parts 21, 22 connected, whereby the connecting elements 28 here and preferably to the bridges 26 the second profile half shell 8 are clipped on.

[0081] For the formation of the door leaf profile 4 the second profile half shell 8in engagement with the insulating bar 9 In the example shown, this is done both indirectly (via the connecting elements 28 the connecting device 10 ) as well as in a direct way, as can be seen particularly well from the upper horizontal profile section of the door leaf profile 4 in Figure 1 There you can see that the second profile half shell 8 in the direction perpendicular to the wing plane 3 in the insulating bar 9 is inserted so that the connecting elements 28 completely into groove-shaped profile sections 16 the insulating bar 9 are immersed or retracted. Furthermore, the webs 26 the second profile half shell 8, where the connecting elements 28 are positively connected, also a little way into the groove-shaped profile sections 16 the insulating bar 9retracted and in these areas directly connected to the insulating bar 9 in contact. The engagement of the second profile half shell 8 and insulating bar 9 therefore consists in the example according to Figure 1 within the meaning of the present application, both directly and indirectly.

[0082] It is easily conceivable that the vertical to the wing plane 3 measured distance between the two profile half-shells 7, 8 is larger than in the Figure 1 shown example. This can be the case, for example, if the thickness 25 the wing filling 2 would be greater in amount than in the Figure 1 shown example. In such a case, the engagement of the second profile half-shell 8 with the insulating bar 9 exist only indirectly, namely via the connecting elements 28 the connecting device 10, because the bridges 26the second profile half shell 8 the groove-shaped profile sections 16 the insulating bar 9 not reach, i.e. would not enter into it. The functionality of the door leaf profile 4 would not be affected. On the contrary, this consideration shows that the door leaf profile 4, which in the embodiment according to Figure 1 is used without restrictions with different wing fillings 2 can be used, the different thicknesses 25 have.

[0083] The design of the connecting elements 28 at the ends of the bridges 26 the second profile half shell 8 offers the advantage that the second profile half shell 8 less far towards the first profile half shell 7 and thereby effectively reduces the distance between the first profile half-shell 7 and the second profile half shell 8is increased compared to a situation in which the webs 26 the second profile half shell 8 significantly further into the groove-shaped profile sections 16 the insulating bar 9 would protrude if they extended to the respective distal, the first profile half-shell 1 facing end of the connecting elements 28 Such a situation, which is also conceivable, is exemplified in the embodiment according to Figure 4 illustrated. As a result of the use of the connecting device 10 with the connecting elements 28 is a heat transfer coefficient of the door leaf profile 4 improved compared to a situation in which fasteners 28 would not be present and the bridges 26 the second profile half shell 8 instead, extend deeper into the groove-shaped profile sections 16 the insulating bar 9would extend.

[0084] The engagement of the second profile half shell 8 with the insulating bar 9 takes place in the direction perpendicular to the wing plane 3 without the formation of a form fit or without form fit. This means that the second profile half-shell 8 in the example shown when installing the door leaf profile 4 continuously in the direction perpendicular to the wing plane 3 on the first profile half shell 7 can be moved without a positive connection being formed in this direction, for example in the form of a latch or the like. The movement of the two profile half-shells 7, 8 in the direction perpendicular to the wing plane 3 towards each other can be continued during assembly until the edging strips 14, 15 the profile half-shells 7, 8 with the interposition of adhesives 20, in contact with the outer surfaces 5, 6the wing filling 2 and the profile half shells 7, 8 cannot be moved any further towards each other. If and as long as the profile half-shells 7, 8 not with the wing filling 2 are or would be glued, with this type of intervention the two profile half-shells 7, 8 non-destructive in the direction perpendicular to the wing plane 3 be moved away from each other again. The movement of the two profile half-shells 7, 8 towards each other in a direction perpendicular to the wing plane 3 enables the desired almost flush connection of the door leaf profile 4 to the wing filling 2.

[0085] The engagement of the second profile half shell 8 with the insulating bar 9 In the example shown, is also designed in such a way that in the direction parallel to the respective profile longitudinal axes 18 the profile parts 21, 22the profile half-shells 8 also does not form a positive connection or the respective engagement is designed without a positive connection. Due to the lack of positive connection in this direction, the second profile half-shell 8 and the insulating bar 9 Furthermore, in the sense of the present application, they are connected to each other without constraint. This design allows movement of the respective profile parts 21, 22 relative to each other in the longitudinal axis-parallel direction, i.e. in the direction parallel to the respective profile longitudinal axis 18. This allows different deformations of the profile half-shells 7, 8 due to temperature differences on both sides of the door leaf 1 be accommodated without the door leaf profile 4 deforms overall, for example, forming an undesirable bulge or the like. This is particularly important for door leaves used on exterior doors.

[0086] The connecting elements 28 are here and preferably compared to the groove-shaped profile sections 16 the insulating bar 9 designed with a certain excess, so that in the course of the engagement of the connecting elements 28 with the insulating bar 9, that is, during the insertion of the connecting elements 28 into the groove-shaped profile sections 16, In the example shown in accordance with Figure 1 the connecting elements 28, which with the lower horizontally oriented profile part 22 the second profile half shell 8 connected, each have an internal cavity. In this way, the connecting elements 28 suitable for inserting into the corresponding groove-shaped profile sections 16 the insulating bar 9to be compressed so that despite a certain excess compared to the groove-shaped profile sections 16 can be inserted into the latter. In this case, the cavity is at least partially overpressed. Due to the stiffness of the material of the connecting elements 28 conditional restoring force, which results from the compression, causes the described frictional engagement in the groove-shaped profile sections 16.

[0087] Alternatively, Figure 1 on the vertically oriented profile part 21 the second profile half shell 8 Fasteners 28 which have a sawtooth-shaped profile. Here, the connecting elements 28 with a certain excess relative to the complementary groove-shaped profile sections 16 the insulating bar 9 designed so that the material of the connecting elements 28when inserting them into said profile sections 16 As explained above, this creates a pressure drop in the material of the connecting elements 28 a restoring force that causes the frictional engagement mentioned.

[0088] This frictional engagement contributes to the fact that, to a certain extent, forces, namely in the form of frictional forces, are directed perpendicular to the wing plane 3 between the insulating bar 9 and the second profile half shell 8 This is especially important for the installation of the door leaf profile 4 advantageous, as unintentional "slipping" between the insulating bar 9 and second profile half shell 8 This frictional connection can nevertheless be released without causing damage, so that the second profile half-shell 8 as such non-destructive in the direction perpendicular to the wing plane 3 again from the insulating bar9 could be removed (as long as the adhesives 20 on the edging strips 14, 15 with the outer surfaces 5, 6 the wing filling 2 not work).

[0089] In a particularly advantageous manner, the two profile half-shells 7, 8 as required when installing the door leaf 1 be moved towards each other until the edging strips 14, 15 as described above to the outer surfaces 5, 6 the wing filling 2 In particular, the design of the profile half-shells 7, 8 or the insulating bar 9 no defined position in the direction perpendicular to the wing plane 3 specified in which the profile half shells 7, 8 to form a properly functioning door leaf profile 4 Instead, the door leaf profile 4 individually to the respective wing filling2 be adjusted by removing the second profile half shell during assembly 8 or the connecting device arranged thereon 10 so far into the insulating bar 9 is inserted as the thickness 25 the respective wing filling 2 This allows and requires a virtually flush connection of the door leaf profile on both sides. 4 to the wing filling 2. "Almost flush" means that a Figure 1 illustrated, perpendicular to the wing plane 3 measured offset 30 between a respective outer surface 5, 6 the wing filling 2 and one of the respective outer surfaces 5, 6 assigned outer surface 29 of a respective profile part 21, 22 the assigned profile half-shell 7, 8 only the sum of a perpendicular to the wing plane 3measured thickness of the bond 20 and a thickness of the profile section of the profile part measured in the same way 21, 22, which the respective edging strip 14, 15 In the illustrated design of the bonding 20 and the profile half shells 7, 8 this offset is 30 Here, and preferably only 3 mm. Such a small offset (up to 8 mm) is referred to in the art and in the context of this application as a "flush connection" or "virtually flush connection."

[0090] Since the profile half shells 7, 8 in the direction perpendicular to the wing plane 3 are not directly or indirectly connected to each other by forming a form fit, a movement of the profile half-shells 7, 8 remain free relative to each other in the direction in question. In other words, the door leaf profile 4in the direction perpendicular to the wing plane 3 not "stick together". In order to achieve this cohesion, the previously mentioned bonding 20 Accordingly, the edging strips 14, 15 the profile half-shells 7, 8 each with an adhesive 20 which are in direct contact with both the respective edging strip 14, 15 as well as with the respective assigned outer area 5, 6 the wing filling 2 The adhesions form 20 a material bond between the wing filling 2 and the respective profile half-shell 7, 8 This causes the profile half shells 7, 8 in the direction perpendicular to the wing plane 3 no longer relative to the wing filling 2 can be moved. Accordingly, the profile half-shells 7, 8effectively also relative to each other in the direction perpendicular to the wing plane 3 determined as soon as they are bonded using the 20 with the wing filling 2 are glued. A force transmission from one of the profile half-shells 7, 8 in the direction perpendicular to the wing plane 3 to the other profile half shell 7, 8 therefore takes place at the door leaf 1 about the bonding 20 and the wing filling 2 instead of.

[0091] The bonding 20 are formed by double-sided adhesive tape. Here and preferably, the adhesive tapes of the bonds 20 Each has a base body formed by an elastomer. This ensures that the bonds 20 have a certain flexibility that allows movement of the wing filling 2 relative to a respective profile half-shell 7, 8,especially in directions parallel to the wing plane 3, The generated range of movement for such relative movements is typically only in the range of about 1 mm / m. It serves to compensate for deformations of the individual components (profile half-shells 7, 8 and wing filling 2 ) due to temperature differences on both sides of the door leaf 1 by appropriate relative movements of the components to each other. This prevents the door leaf 1 deformed in an undesirable way. The bonding 20 extend here and preferably each over an entire, parallel to the respective profile longitudinal axis 18 measured length of the respective edging strip 14, 15 of the respective profile part 21, 22.

[0092] The engagement of the second profile half shell 8 into the insulating bar 1occurs in a direction perpendicular to the respective profile longitudinal axis 18 of the respective profile part 21, 22 and parallel to the wing plane 3 in such a way that the profile half-shell 8 and the insulating bar 9 directly and / or indirectly form a form fit. This is particularly evident in the case of Figure 1 . There you can see that the bridges 26 including the connecting elements connected to it 28 in the groove-shaped profile sections 16 the insulating bar 9 intervene so that a relative movement of the second profile half-shell 8 to the first profile half shell 7 or to the insulating bar firmly connected to the latter 9 in the direction parallel to the wing plane 3 and perpendicular to the respective profile longitudinal axis 18 In this way, forces acting on the door leaf profile 4in the direction mentioned, between the two profile half-shells 7, 8 This also results in a correspondingly distributed force introduction via the bonding 20 into the wing filling 2 or vice versa.

[0093] In a second embodiment, which is based on the Figures 2 and 3 results, the connecting device 10, which is firmly connected to the second profile half-shell 8, in comparison to the first embodiment according to Figure 1 designed differently. While the connecting device 10 in the embodiment according to Figure 1 a plurality of individual connecting elements 28 includes the connecting device 10 in the embodiment according to the Figures 2 and 3 from a second insulating bar 27 This second insulating bar 27comprises a plurality of elongated web parts 23, 24, where each of the horizontally oriented profile parts 22 the second profile half shell 8 a horizontally oriented web part 24 of the second insulating bar 27 and each of the vertically oriented profile parts 21 the second profile half shell 8 a vertically oriented web part 23 the second insulating bar 27 are assigned. The web parts 23, 24 the second insulating bar 27 extend parallel to the respective profile longitudinal axis 18 of the respective profile part 21, 22 the second profile half-shell 8. Here and preferably the web parts extend 23, 24 each over the entire length of the respective profile part 21, 22. The bridge parts 23, 24 are made of extruded plastic profiles.

[0094] In the example shown, the web parts 23, 24 of the second insulating bar 27 two spring-shaped profile sections each 17 which are designed and equipped to be divided into complementary groove-shaped profile sections 16 of the first insulating bar 9 to retract or intervene. The installation of the door leaf profile 4 runs analogously to the embodiment according to Figure 1 . Accordingly, during assembly, the second profile half shell 8 together with the permanently attached connecting device 10 in the direction perpendicular to the wing plane 3 on the first profile half shell 7 or the first insulating bar fixed to it 9 to move so that the spring-shaped profile sections 17 the connecting device 10 into the groove-shaped profile sections 16 the insulating bar 9This is done according to the above description without the formation of a form fit in the direction perpendicular to the wing plane 3 of the door leaf 1. Therefore, the second profile half shell 8 so far in the direction of the first profile half shell 7 be moved until the second profile half shell 8 with its edging strip 15 with the bonding in between 20 to the corresponding edge area 13 the outer surface 6 the wing filling 2 Here, too, the door leaf profile closes as desired 4 flush or almost flush with the sash filling 2 to.

[0095] The design of the connecting device 10 in the form of a second insulating bar 27 offers the advantage that the effective distance between the two profile half-shells 7, 8 compared to the Figure 1shown embodiment can be further enlarged so that the heat transfer coefficient of the door leaf profile 4 is comparatively low. For the assembly of the connecting device 10 on the second profile half shell 8 However, a design of the connecting device 10 with a plurality of individual connecting elements 28 according to the embodiment in Figure 1 be beneficial.

[0096] In a further embodiment, which results from Figure 4 The second profile half shell is 8 only directly in engagement with the insulating bar 9 of the door leaf profile 4. Here, the second profile half shell 8 in the direction perpendicular to the wing plane 3 extending bridges 26 which are intended and equipped to do so during the assembly of the door leaf 1in a direction perpendicular to the wing plane 3 into groove-shaped profile sections 16 the insulating bar 9 For the installation of the door leaf profile 4 This design is the simplest of the examples shown here, since the door leaf profile 4 no connecting device 10 which is connected separately to the second profile half-shell 8 From the point of view of energy efficiency, however, this design is disadvantageous compared to the previously described ones, since the webs 26 the second profile half shell 8 comparatively close to the first profile half shell 7 reach (and thus deep into the groove-shaped profile sections 16 the first profile half-shell 7 retracted), so that at least mathematically the heat transfer coefficient of the door leaf profile 4compared to the solutions that use a connecting device 10 use, is at a disadvantage.

[0097] Another example is shown in Figure 6 . This is similar to the embodiment according to Figure 1 The door leaf shown 1 includes a connecting device 10 with block-shaped connecting elements 28, which deviates from the embodiment according to Figure 1 The connecting elements 28 are provided with an associated recording 32 the profile parts 21, 22 the second profile half shell 8 connected, whereby during assembly by screwing in a screw a not shown, in the holder 32 located expansion element of a respective connecting element 28 spread out and in this way in the recording 32 The one with the first profile half shell 7connected insulating bar 9 has two groove-shaped profile sections 16 , whereby the first groove-shaped profile section 16 in its dimensions to the connecting elements 28 is matched, while the second groove-shaped profile section 16 in its dimensions on a bridge 26 the second profile half shell 8 As can be seen particularly from the upper part of the figure according to Figure 6 which results in the door leaf 1 in a fully assembled state, the second profile half shell engages 8 here both indirectly and directly with the insulating bar 9 The indirect intervention takes place via the connecting elements 28 in cooperation with the first groove-shaped profile section 16 and the immediate intervention takes place via the bridge 26 with the second groove-shaped profile section 16.

[0098] The door leaf according to the invention 1 can be used particularly advantageously in the form of a sliding door leaf, especially for an automatic sliding door. For safety reasons, the almost flush connection of the leaf filling is 2 to the door leaf profile 4 or conversely particularly advantageous to avoid the risk of injury when operating the door leaf 1 When used as a sliding door, the door leaf has 1 preferably along one of the wing fillings 2 opposite side of a vertical profile section of the door leaf profile 4 at least one sealing contour 31 In the Figure 5 In the embodiment shown, the door leaf comprises 1 two sealing contours extending parallel to each other 31 which are perpendicular to the wing plane 3are arranged next to each other. The wing filling 2 is in Figure 5 Not shown to simplify illustration. The sealing contours 31 can each be formed by an extruded plastic profile and extend at least substantially over the entire height of the door leaf 1 They are attached to one of the wing panels in such a way 2 opposite end face of the door leaf profile 4 arranged in such a way that they are designed to cooperate sealingly with a complementary sealing partner. This is intended in particular to ensure an at least substantially windproof and rainproof connection of the door leaf 1 to a respective component to which the door leaf 1 strikes.

[0099] In a preferred embodiment of a respective automatic sliding door, the same can have two sliding door leaves, wherein both sliding door leaves are arranged on the mutually facing end faces of the respective door leaf profile 4 of the respective door leaf 1 complementary shaped sealing contours 31 so that the sealing contours 31 When the automatic sliding door is in a closed position, they engage with each other to form a seal.
