Description

[0001] The present invention relates to a door arrangement for separating an exterior space from an interior space.

[0002] The door arrangement according to the invention is in particular a revolving door arrangement, including a pivot door arrangement, with force-transmitting linkage.

[0003] In such door arrangements, the door drive, the linkage and the guide rail in which the linkage is guided are usually installed in such a way that they are visible when approaching a door, regardless of whether the door leaf is in the closing or opening position.

[0004] To meet even the highest aesthetic standards, it is desirable to install the aforementioned components in such a way that they are as visually unobtrusive as possible. This allows for a more harmonious integration of the door into architecturally sophisticated environments. In addition to design advantages, concealing the door drive, linkage, and guide rail also offers functional benefits, as hidden components are better protected from external influences such as dirt, moisture, or mechanical damage. Furthermore, the concealed design facilitates cleaning.

[0005] A common solution for aesthetic improvement involves automating doors using underfloor drives, and for very large door elements, even gate drives. However, these drive systems are susceptible to weather-related problems. In particular, water ingress and the limited sealing of the systems mean that sensitive electronic components are exposed to the elements, which can impair their functionality and lifespan. Furthermore, such solutions typically require extensive concrete excavations, significantly increasing installation costs.

[0006] DE 197 56 496 C2 relates to a revolving door drive with an electronic control unit comprising at least one memory and a microprocessor, for a door with at least one leaf, the leaf of which is driven by an electromechanical drive unit acting in the opening and closing direction, wherein the drive unit essentially consists of a drive motor with a power transmission unit connected thereto, and the power transmission unit has a drive shaft which is connected to one end of an actuating lever and the entire revolving door drive is invisibly installed within a door leaf or within a frame.

[0007] Although DE 197 56 496 C2 provides a solution for visually concealing the door drive, the disclosed actuating arm remains visible towards the guide rail and may be perceived as visually disturbing. Measures or structural designs for visually concealing the guide rail are also not disclosed.

[0008] Even with the well-known underfloor drives (unless they are direct drives), there is the problem of visible and therefore potentially disruptive drive components. EP 3 748 113 A1 relates to a door assembly for installation in or on a wall opening in a wall. DE 69 35 779 U Rotary device for a swing door. DE 10 2006 004 661 A1 relates to a gearbox arrangement with a frame and a revolving door and an actuating arm arrangement for a concealed drive or door closer above the frame. DE 195 40 505 A1 relates to a door closer with automatic closing movement, comprising a closer housing concealed in the area of ​​the door jamb or door frame and a force-transmitting linkage.

[0009] It is therefore an object of the present invention to provide a door assembly in which at least the linkage, particularly in the closed position of the door, is largely concealed. At the same time, the door assembly should be easy to install.

[0010] According to one aspect of the present invention, this problem is solved by a door arrangement according to claim 1. The door arrangement according to the invention (for separating an exterior space from an interior space) has the following features: - a frame with a frame part which, when installed, runs essentially parallel to the longitudinal direction of a door lintel and at least partially conceals the door lintel, wherein the frame part has a through opening, - a door leaf; - a rod; and - a door drive, wherein the door drive is arranged between the frame and the lintel and is configured to drive the door leaf rotatably about an axis of rotation relative to the frame via the linkage, wherein the door drive has an output shaft which is configured to be passed through the opening of the frame part and coupled to the linkage.

[0011] According to the invention, the door assembly is designed such that the door drive is positioned between the frame and the door lintel. This allows for installation above the door leaf. As a result, the door drive is not only visually concealed but also protected from external influences.

[0012] Furthermore, the output shaft of the door drive is routed through the opening in the frame and not, as is usual, alongside the frame or outside the plane of the door leaf. Since the output shaft is (directly) connected to the linkage, with its axis of rotation coinciding with that of the linkage, the arrangement of the output shaft also affects the arrangement of the linkage in relation to the frame.

[0013] The door assembly is designed, due to the passage of the output shaft through the frame, such that, when the door leaf is closed, the linkage, viewed along the longitudinal direction of the drive shaft (i.e., in the direction of gravity), is at least partially located behind the frame and thus concealed by it. In other words, when the door is closed, the linkage lies, at least partially, within a projection defined by the frame's contour. This applies particularly to the section of the linkage connected to the output shaft recessed in the frame, especially to the section whose axis of rotation coincides with that of the output shaft. Therefore, in the closed position, the linkage protrudes only partially from the plane of the door leaf and is essentially hidden from view.At the same time, the frame is protected against mechanical damage or tampering, which is particularly advantageous in public spaces.

[0014] The linkage is preferably designed as a (single) lever arm. This lever arm design enables particularly effective torque transmission to the door leaf.

[0015] With the door arrangement according to the invention, opening angles of the door up to and including 120° can be achieved.

[0016] Overall, the present design offers not only the advantage of an aesthetically pleasing door arrangement, but also enables a mechanically simple yet highly functional connection between the drive and the door leaf. The proposed door arrangement is particularly suitable for large and heavy swing doors. The building connection can be made in the same way as with a standard door arrangement.

[0017] The proposed door arrangement can be a standard swing door, where the door leaf is connected to the door frame or jamb via vertical hinges. However, it can also be a pivot door. This type of door is characterized by the fact that the door leaf is not supported by traditional side hinges, but rather by pivot points (so-called pivot hinges) located at the top and bottom, positioned at a distance from the edge of the door leaf. This results in a pivot axis that is not aligned with the edge of the door leaf, but rather runs within the door leaf itself. In other words, pivot doors do not rotate around a vertical axis like conventional swing doors, which is defined by a hinge on the side of the door leaf. Instead, this axis is typically located near the center of the door leaf or asymmetrically positioned between the center and the side edges of the door leaf.This allows for larger door leaves, an elegant appearance and flush integration into modern architectural concepts.

[0018] The terms "exterior" and "interior" are not to be understood literally in this context and are not intended to have a restrictive effect. Thus, "exterior" does not necessarily refer to an outdoor area, just as "interior" does not necessarily mean an enclosed interior space. Rather, both terms serve solely to distinguish the areas separated by the door arrangement. Therefore, the terms can easily be used interchangeably. In the case of standard revolving doors, the term "exterior" can be considered the space on the hinge side, while the term "interior" can be considered the space on the opposite side.

[0019] According to one embodiment, the linkage has at a first end a first connecting part for connecting the linkage to the output shaft, wherein the first connecting part is designed to be, preferably completely, recessed in the through-opening of the frame, and / or wherein the first connecting part is designed as a sleeve for receiving the output shaft.

[0020] Due to the aforementioned arrangement of the first connecting element, the first connecting element is located (preferably completely) within the passage opening and can therefore be (preferably completely) concealed by the frame. This applies particularly to a top view of the door assembly, i.e., the view a person has when approaching the door (from the outside or inside).

[0021] The design of the first connecting part as a sleeve enables a particularly simple connection between the output shaft and the linkage. The sleeve and the output shaft are preferably designed to provide a positive-locking and rotationally fixed connection between them. The sleeve is preferably welded to the (remaining) linkage.

[0022] In a further embodiment, the output shaft has external teeth at its end facing the linkage, and the sleeve has internal teeth that match the output shaft. Alternatively or additionally, the output shaft has a blind hole at its end facing the linkage for receiving a connecting element to connect the linkage to the output shaft.

[0023] By providing a splined connection between the output shaft and the linkage sleeve, a particularly stable, rotationally resistant connection between the output shaft and the linkage is achieved.

[0024] A blind hole in the output shaft, aligned along its longitudinal axis, and a through hole (aligned with this through hole) in the first connecting part allow for a rotationally fixed coupling between the output shaft and the linkage by means of a connecting element inserted therein. Simultaneously, axial relative movement of the linkage along the longitudinal axis of the output shaft is effectively prevented. A pin, screw, rivet, or a positive-locking bolt can be used as the connecting element. The output shaft is preferably designed as a solid shaft. However, a hollow shaft design is also conceivable. In the latter case, the blind hole is then formed as part of the hollow shaft's cavity.

[0025] A rotationally fixed, stable connection between the output shaft and linkage ensures reliable torque transmission; the blind hole allows for easy attachment with various connecting elements.

[0026] In a further embodiment, the door leaf of the door assembly has a slide rail for coupling with the linkage, wherein the slide rail is preferably completely integrated into the door leaf.

[0027] Preferably, the guide rail is housed in a recess or recess provided for this purpose on the side of the door leaf facing the lintel. The guide rail is preferably completely enclosed in the recess so that it does not protrude beyond the adjacent surface of the door leaf. Particularly preferably, the upper edge of the guide rail is flush with the adjacent side of the door leaf. This type of arrangement allows for a compact, space-saving, and visually unobtrusive guide for the linkage within the door leaf.

[0028] In one embodiment of the door arrangement, the linkage has a second connecting part at a second end for connecting the linkage to the slide rail, the slide rail being designed to receive the second connecting part, preferably completely.

[0029] This means that the second connecting part is not only concealed by the sliding rail, but also by the door leaf due to the integration of the sliding rail into the door leaf.

[0030] The second connecting element is designed, in particular, as a guide pin or roller pin, which is configured to be received by and guided by the slide rail. Alternatively, the second connecting element can, for example, be designed as a guide carriage, and the slide rail as a linear ball bearing, with the guide carriage being configured to slide almost frictionlessly in the slide rail.

[0031] Provided the guide rail is recessed in a groove or recess on the side of the door leaf facing the lintel, and the second connecting part is essentially completely enclosed by the guide rail, the linkage is prevented from leaving the plane of the door leaf when the door leaf is closed. If the linkage is a lever arm (with the first end opposite the second end), it will, under the aforementioned conditions, run essentially parallel to the plane of the door leaf when the door is closed. In this way, the linkage can be completely concealed when the door is closed.

[0032] In a further embodiment of the door arrangement, the door leaf has a first projection on the outside facing the door head, which is designed in such a way that it conceals the linkage when viewing the door leaf from the outside, at least when the door leaf is in the closed position, preferably completely.

[0033] To form the first projection (which can also be called the first door stop), the door leaf preferably has a rebate on its side facing the headboard. The rebate does not need to extend over the entire length of this side of the door leaf, as long as it allows the linkage to be received when the door is closed. Instead of a rebate on the door leaf, a recess or cutout for receiving the linkage on the side of the door leaf facing the headboard is also conceivable.

[0034] The formation of the first projection creates a cladding element that serves to remove the linkage from view, at least in the closed position.

[0035] In a further embodiment, the frame part of the frame has a second projection on the inside side facing away from the door lintel, wherein the second projection is designed in such a way that it conceals the linkage when viewing the door leaf from the inside, at least when the door leaf is in the closed position, preferably completely.

[0036] To form the second projection (which can also be called the second door stop), the frame section preferably has a rebate on its side facing away from the door head. The rebate does not need to extend over the entire length of the frame section, as long as it accommodates the linkage in the closed position. Instead of a rebate, a recess can also be provided on the side of the frame section facing away from the door head.

[0037] In one embodiment, the door arrangement further comprises a mounting plate which is designed to be arranged on a side of the frame part facing the door head, wherein the mounting plate has a through hole for the passage of the output shaft and a bearing for supporting the output shaft.

[0038] The mounting plate facilitates the integration of the door drive into various profile systems. It serves not only to position and support the output shaft, but also, and more importantly, to absorb and distribute mechanical forces. The torque-induced load on the output shaft during operation generates both radial and axial forces. These forces are transferred to the plate via the integrated bearing. The mounting plate, in turn, distributes these forces across the frame, significantly reducing point loads and the associated material stresses in the area of ​​the door opening.

[0039] The bearing is preferably placed on the mounting plate in the area of ​​the through hole and, in particular, screwed onto the mounting plate.

[0040] In a preferred embodiment, the bearing is designed as a plastic bearing.

[0041] The design as a plastic bearing ensures quiet, low-friction, and durable support of the output shaft without the need for regular maintenance or lubrication. Its corrosion resistance and low weight also contribute to increased operational reliability and easy integration into various door profile systems.

[0042] In a further embodiment, the height of the door drive along the longitudinal direction of the output shaft, without taking the output shaft into account, is less than 150 mm, preferably less than 145 mm, particularly preferably less than 141 mm.

[0043] This flat design allows the proposed door arrangement to be used even in confined architectural situations, e.g. with reduced lintel openings or delicate facade profiles.

[0044] It is understood that the features mentioned above and those to be explained below can be used not only in the combinations specified, but also in other combinations or on their own, without leaving the scope of the present invention.

[0045] Exemplary embodiments of the invention are shown in the drawings and are explained in more detail in the following description. They show: Fig. 1 a schematic view to illustrate the basic structure of a first embodiment of the door arrangement according to the invention; Fig. 2 a section of a schematic sectional view of a second embodiment of the door arrangement according to the invention; Fig. 3 den in Fig. 2. Section shown in a view perpendicular to the plane of the door leaf; Fig. 4 a schematic view of a third embodiment of the door arrangement according to the invention from above; Fig. 5 a schematic view of a fourth embodiment of the door arrangement according to the invention from above; and Fig. 6 a further schematic view of the fourth embodiment of the door arrangement according to the invention from above.

[0046] Fig. Figure 1 shows a schematic representation of a first embodiment of the door arrangement according to the invention. The door arrangement as a whole is designated by reference numeral 100.

[0047] The door assembly 100 is designed as a regular revolving door (i.e., specifically not as a pivot door). It has a door leaf 12, which can also be referred to as a door panel 12. In the embodiment shown here, the door panel or door leaf 12 comprises a glass pane 14, which is set in a sash frame 16.

[0048] It is understood that the door leaf 12 does not necessarily have to be made of glass, but can also be made of other materials (e.g., metal or wood). Likewise, the door leaf 12 can also be frameless (i.e., without a sash frame 16).

[0049] The door leaf 12 is pivotable relative to a fixed frame 18 about a rotation axis 20. The rotation axis 20 runs laterally along the vertical side of the frame 18 in a vertical direction.

[0050] The frame 18 encloses the door leaf 12 and forms the structural basis of the door assembly or door 100. The frame 18 thus forms the fixed, immovable part of the door 100, relative to which the door leaf or door wing 12 (e.g. including wing frame and glass pane) is pivoted.

[0051] Furthermore from Fig. Figure 1 shows the door drive 10, which is installed above the door leaf 12. More precisely, the door drive 10 is installed below the door lintel 24 and is located in the area between the door lintel 24 and the frame 18. Specifically, only part of the door drive 10 is installed between the frame 18 and the door lintel. Part of the output shaft 26 extends into or through a through-opening 184 in the frame 18.

[0052] The output shaft 26 is non-rotatably connected at its lower end, i.e., the end facing away from the door lintel, to a linkage 14. The axis of rotation of the linkage 14 (in this case, a lever arm) coincides with the axis of rotation of the output shaft 26 on the side connected to it. Since the linkage 14 is connected on its other (opposite) side to the door leaf 12 (more precisely, to a guide rail 70 arranged on the door leaf), a rotation of the output shaft 26 results in a movement of the door leaf 12.

[0053] The door drive 10 is a door drive that is mounted almost completely concealed and is hardly visible to a user. Only a lower part of an output shaft 26 protrudes from the frame 18.

[0054] This complete integration of the door drive 10 into the door frame 18 and the space provided on-site between the door frame 18 and the door lintel 24 is possible in particular due to the comparatively low installation height of the door drive 10. Preferably, the door drive 10 requires a vertical space of only 140 mm.

[0055] The arrangement of the output shaft 26 and the type of connection between the output shaft 26 and the linkage 14 ensure that the linkage is concealed by the frame 18, at least in the area of ​​the output shaft 26 (at least in the closed position) (when viewed in the direction of gravity). This allows the linkage 14 to protrude only minimally from the plane of the door leaf. The plane of the door leaf thus falls within Fig. 1 together with the sheet plane and is the plane that is spanned by the main side of the door leaf 12.

[0056] The described design creates an aesthetically pleasing door arrangement.

[0057] Fig. Figure 2 shows a section of a schematic sectional view of a second embodiment of the door arrangement or door 100 according to the invention. The door 100 or the door leaf 12 is in the closed position. Thus, the plane of the door leaf essentially lies in the plane spanned by the frame 18.

[0058] The section shown here only shows the upper part of the door assembly 100, i.e., the part facing the door lintel 24. Therefore, parts of the frame 18 and the door leaf 12 or the door leaf frame 16 are not shown.

[0059] As from Fig. As can be seen in the second embodiment, the door drive 10 is located essentially in a gap between the frame 18 and the door lintel 24. Only the output shaft 26 of the door drive 10 protrudes from this gap.

[0060] The output shaft 26 has an external toothing at its upper end (the end facing the door lintel 24), which corresponds to and engages with an internal toothing provided on the transmission hollow shaft of the motor-gearbox unit of the door drive 10 (not shown in detail).

[0061] The output shaft 26 penetrates the frame 18, or more precisely, the horizontally extending frame section 182 of the frame 18. For this purpose, the frame section 182 is provided with a vertically extending passage opening 184. The passage opening 184 extends from the side of the frame section 182 facing the door head 24 (hereinafter also referred to as the frame section door head side 183) to the side of the frame section 182 facing away from the door head 24 (hereinafter also referred to as the frame section bottom side 185). The passage opening 184 could, for example, be a borehole or the like. The Fig. The two dashed lines indicating the passage opening 184 are merely meant to suggest its course and are not to be interpreted as defining its boundaries. The frame may contain cavities within it through which the passage opening 184 passes.

[0062] To facilitate the guidance of the output shaft 26 through the through-opening 184, a mounting plate 80 is provided on the frame part door head 183. The mounting plate 80 has a through-hole 82 for the passage of the output shaft 26. The mounting plate is attached to the frame part 182 (in this case, the mounting plate 80 is screwed onto the frame part 182) such that the through-hole 82 is aligned with the through-opening 184 of the frame part 182. A bearing 84 mounted on the mounting plate 80 ensures frictionless and secure support of the output shaft 26.

[0063] In the Fig. In the embodiment shown in Figure 2, the output shaft 26 does not penetrate the frame part 182 completely on all sides. Therefore, on the side of the frame part 182 facing away from the door lintel (frame part bottom side 185), it is not visible from at least one side in a top view of the door leaf 12.

[0064] The lower part of the output shaft 26, i.e., the part facing away from the door lintel 24, is connected to the linkage 14 of the door assembly 100. In this case, the linkage 14 is a lever arm. It is also conceivable, in principle, to use a linkage with two interconnected lever arms.

[0065] The lever arm is connected to the output shaft 26 via a first connecting part 142 of the lever arm. In the illustrated embodiment, the first connecting part 142 is a sleeve with internal teeth that engage with external teeth on the output shaft 26 at its lower end. The teeth create a rotationally fixed connection between the output shaft 26 and the sleeve or linkage 14. To achieve a secure connection with the lever arm in one direction as well, along the longitudinal or rotational axis of the output shaft 26, the output shaft 26 has a blind hole 264 extending in the direction of its axis of rotation 262. The first connecting part 142 also has a hole. An axially fixed connection between the output shaft 26 and the lever arm can also be created via a connecting element 90 that passes through these holes.The connecting element 90 can, for example, be a screw, whereby the blind hole (and possibly also the hole in the first connecting part 142) has a corresponding internal thread for receiving the screw.

[0066] Due to the particularly rotationally rigid connection between the output shaft 26 and the lever arm, a rotation of the output shaft 26 inevitably leads to a rotation of the first connecting part 142, or the lever arm. To effect movement of the door leaf 12, the lever arm is equipped on its opposite side – i.e., the side facing away from the first connecting part 142 – with a second connecting part 146. This second connecting part 146 is received in a slide rail 70. It cannot detach from the slide rail 70 but is movable within it along a defined path. In the illustrated embodiment, the second connecting part 146 comprises a roller bolt, which enables rolling support and low-friction movement within the slide rail 70.Other designs of the second connecting part 146 are also conceivable, for example by means of sliding bearings or ball head connections, depending on the respective requirements for mobility, power transmission and noise behavior.

[0067] The guide rail 70 is fixedly connected to the door leaf 12. Accordingly, a rotation of the output shaft 26 ultimately causes a rotation of the door leaf 12. The guide rail 70 is integrated into the door leaf 12. For this purpose, the door leaf 12 has a recess (not shown in detail) on its side facing the door head 24 (hereinafter also referred to as the door leaf head 123), into which the guide rail 70 is fully received.

[0068] As already mentioned in Fig. As indicated in Figure 2, the components used for the drive of the door leaf 12 are essentially not visible in a top view of the door leaf 12. The door drive 10, including the output shaft 12, is arranged in a space above or within the frame 18 itself. Furthermore, the linkage 14 and the guide rail 70 are also visually concealed behind the frame 18 or within the door leaf 12 due to their arrangement.

[0069] To better understand the arrangement of the components of the door drive 100 according to the second embodiment, the following is shown. Fig. 3 den in Fig. 2. Section shown in a view perpendicular to the door leaf plane.

[0070] As in Fig. As can be seen in Figure 3, the door arrangement 100 separates an outer space 2 from an inner space 4. In the closed position of the door 100 shown, neither the output shaft 26 nor the linkage 14 nor the guide rail 70 are visible in the outer space 2 (i.e., on the hinge side) and the inner space 4 (i.e., on the inside of the hinge).

[0071] As already described, the lower end of the output shaft 26 is connected to a first connecting part 142 of the linkage 14, or rather, due to its design as a sleeve, is surrounded by it. From the outside 2, a first projection 122 of the door leaf 12, which points towards the door lintel 24, ensures that the first connecting part 142 is visually concealed. From the inside 4, a second projection 186 of the frame part 182 of the frame 18, which points away from the door lintel 24, conceals the first connecting part 142.

[0072] The linkage 14 is similarly concealed by the two projections 122 and 186.

[0073] The second connecting part 146 of the linkage 14, in turn, is concealed by the door leaf 12 both towards the outside 2 and the inside 4 due to the recessing of the sliding rail 70 in the door leaf 12.

[0074] As from Fig. As can be deduced from point 3, the aforementioned components are also concealed in the open position, at least when viewed perpendicular to the plane of the door leaf. Only when viewed from an "unnatural" perspective, for example from an oblique angle below, are not all of the aforementioned components completely concealed.

[0075] Fig. Figure 4 shows a schematic view of a third embodiment of the door arrangement 100 according to the invention from above, i.e. in a view in the direction of gravity.

[0076] Door 100 is a "classic" revolving door, and therefore not a pivot door. The axis of rotation around which door 100 turns is designated by the reference numeral 20. The door assembly 100 is shown in the closed position, as well as in an open position with a 90° opening angle and an open position with a 120° opening angle. The door drive 10 and the frame 18 are omitted from the illustration. The door leaf 12 is shown in a top view of the door leaf head 123 in various positions.

[0077] The in Fig. The arrangement shown in Figure 4 includes (in addition to the aforementioned omitted components) in particular a door leaf 12 with a sliding rail 70 and a linkage 14. This is designed as a lever arm.

[0078] At one end of the lever arm is a first connecting element 142, which connects the lever arm to the output shaft 26. The connection between the lever arm and the output shaft 26 is designed to be rotationally fixed. The lever arm therefore rotates about the axis of rotation 262 of the output shaft 26.

[0079] At its second end, the lever arm has a second connecting part 146 that connects the lever arm to the slide rail 70. The second connecting part 146 can move freely within the slide rail 70.

[0080] The guide rail 70 is integrated into the upper surface of the door leaf 12, more precisely the door leaf head 123, and runs essentially parallel to the plane of the door leaf (not further specified). In the closed position of the door 100, the lever arm therefore also runs in this plane. When the door 100 is opened, the lever arm is rotated out of this concealed position about the pivot axis 262.

[0081] With appropriate profiling of the door leaf 12 (see Fig. 3) By providing a rebate, for example, it is possible to prevent the lever arm from being visible when viewed in a direction perpendicular to the plane of the door leaf (from the hinge side) in both the closed and open positions (viewing direction B).

[0082] Fig. Figure 5 shows a schematic view of a fourth embodiment of the door arrangement 100 according to the invention from above, i.e. in a view in the direction of gravity.

[0083] Door 100 is not a "classic" revolving door, but a pivot door. The axis of rotation around which door 100 turns is designated by the reference symbol 20. The door assembly 100 is shown in the closed position as well as in various open positions facing the exterior space 2. In particular, the door leaf 12 is shown in a top view of the door leaf head 123 in various positions. The door drive 10 and the frame 18 are omitted from the illustration.

[0084] How Fig. The door leaf 12, which can be removed from the door leaf, has a guide rail 70 integrated into the door leaf head 123. The guide rail 70 is connected to the output shaft 26 of the door drive 10 via a linkage 14, more precisely the first connecting part 142 of the linkage 14. The linkage 14 is designed as a lever arm. As shown in the diagram, the guide rail 70 is connected to the output shaft 26 of the door drive 10 via a linkage 14, or more precisely, the first connecting part 142 of the linkage 14. Fig. As can be seen in Figure 5, the lever arm, when the door 100 is closed, is essentially in a position where it runs parallel to the guide rail 70. In particular, it does not protrude from the plane of the door leaf or the door leaf head 123, or rather, it runs within the plane of the door leaf. Only when the door 100 is opened does the lever arm leave this plane and emerge from under the (not shown) frame 18.
