Description

[0001] The invention relates to a sliding door for a building or a room.

[0002] Unlike a hinged door, a sliding door leaf does not pivot around a central axis. Instead, it slides along a wall, either to a passageway or an opening in the wall where the door is mounted, or within the wall itself, to open or close. Furthermore, sliding doors are characterized by their ability to be suspended or vertically guided.

[0003] EP 3 333 347 A1 describes a lift-and-slide door. The lift-and-slide door comprises a sash, a roller assembly, and a track. The track defines a path along which the sash can be moved by means of the roller assembly. Furthermore, the track has at least one lowering section that is adjustable between a flush position and a lowered position, in order to move the sash between a raised operating position and a lowered fixed position when the sash is resting on the lowering section with a roller of the roller assembly.

[0004] German patent application DE 100 11 245 C2 describes a sliding door for closing a wall opening. The sliding door comprises a door leaf, rollers supporting the door leaf and held against the wall, and a suspension system with a running and guide rail. The running and guide rail for the rollers has a track such that, when the door leaf moves into the closed position, it is offset and lowered parallel to the wall opening. This lowering action charges the energy storage elements of the sliding door. Furthermore, the sliding door has a support rail that runs parallel to the running and guide rail and is in contact with the rollers when the door is in the closed position. The support rail is braced against the wall by the energy storage elements and is movable relative to the running and guide rail in the direction of the door leaf's descent.

[0005] Further drop-down sliding doors are described in EP 1 555 369 A1, DE 103 34 588 B3 and DE 101 07 028 A1.

[0006] The invention aims to further develop a sliding door for a building or a room in such a way that the sliding door, when closed or in a closed position of the door leaf, is sealed in a particularly simple and reliable manner, especially with regard to sound and / or smoke protection, and is also secured against forced entry.

[0007] This problem is solved by a sliding door with the feature of the independent patent claim. Advantageous embodiments are the subject of the dependent claims.

[0008] To solve this problem, the invention provides a sliding door for a building or room. The sliding door comprises a door leaf that can be moved from an open position to a closed position during a closing process. In other words, the door leaf of the sliding door can be closed during a closing process. In particular, the door leaf, in the open position, provides a passageway for the sliding door and, in the closed position, closes off this passageway. Preferably, the door leaf, in the closed position, is arranged at least partially or completely within or adjacent to the passageway, especially to close off the passageway. In particular, the door leaf is dimensioned such that it covers the passageway in the closed position. Preferably, the passageway and / or the door leaf are rectangular. Furthermore, the door leaf can be made of wood and / or metal.The term "passage area" refers in particular to a wall opening or penetration, especially where the sliding door is located. Furthermore, the sliding door has a guide device, the door leaf being held so that it can be moved by means of this guide device. In other words, the door leaf can be moved or shifted and / or held and / or guided by means of the guide device. Preferably, the door leaf can be moved or guided from the open position to the closed position and back again from the closed position to the open position by means of the guide device. A particularly preferred feature is an opening and closing mechanism designed to ensure the largest possible opening width.

[0009] Furthermore, the guide mechanism is designed to move the door leaf in such a way that it lowers itself into the closed position, creating a tight seal. "Sealing" in this context means, in particular, that the door leaf, when closed, closes flush with the opening, completely closes or covers the opening, or fills the opening. "Lowering" in this context means, in particular, that the guide mechanism moves the door leaf perpendicular to a direction of movement, especially upwards. Thus, the guide mechanism can initially move the door leaf from the open position in directions perpendicular to the upward direction of movement, until it reaches the closed position.When the door leaf is closed, the guide mechanism lowers or lowers it downwards, i.e., in the upward direction or in a direction of gravity of the door leaf or sliding door. In other words, the door leaf can slide down into a lowering plane.

[0010] The guide mechanism and the lowering process in the closed position ensure that the sliding door is completely closed. This makes it particularly easy and reliable to seal the sliding door, especially the opening. Furthermore, the guide mechanism makes it especially easy for children and the elderly to open the sliding door.

[0011] Furthermore, the guide device comprises a guide rail and a guide carriage, wherein the door leaf is held slidably along the guide rail by means of the guide carriage. In other words, the door leaf can be attached or fixed to the guide carriage and moved or transported along the guide rail with it. The "guide carriage" can also be referred to as a carriage. In particular, the guide rail is designed for sliding guidance, especially linear guidance, of the door leaf. The guide rail can be designed as a profile rail. Furthermore, the guide rail can be made of metal, plastic, or wood. Preferably, the door leaf is held slidably suspended from the guide carriage and / or the guide rail. With the aid of the guide rail and the guide carriage, the door leaf can be moved particularly easily from the open position to the closed position and / or vice versa.

[0012] Furthermore, the guide carriage has at least one guide roller which is movable along the guide rail. "Guide roller" refers in particular to a roller or wheel which is rotatably mounted about an axis. The guide roller can also be called a running roller. Preferably, the at least one guide roller is designed as a flanged roller. A flanged roller is, in particular, a roller which has a projection, flange, or shoulder extending, in particular radially, around one end of the roller. With the aid of the projection, the flanged roller can be positioned against a surface of the guide rail, which is arranged in particular perpendicular to the rolling surface, and in particular flush with the surface. Advantageously, the guide roller is arranged on a guide surface of the guide rail, which can also be referred to as the rolling surface.If the guide roller is designed as a flanged roller, it can be arranged on or in contact with the guide surface and with a surface of the guide rail arranged perpendicular to the guide surface, particularly by means of its extension. The flanged roller specifically comprises a support roller arranged on the guide surface and a roller-shaped extension extending around the support roller, which in turn abuts the surface of the guide rail arranged perpendicular to the guide surface. In particular, a flange of the flanged roller abuts the surface of the guide rail arranged perpendicular to the guide surface. The at least one guide roller ensures safe and reliable guidance of the sliding door leaf.

[0013] Advantageously, the sliding door can have an additional guide carriage with a further guide roller, wherein the door leaf is held or suspended from both guide carriages. In other words, the door leaf can be held by two guide carriages, each with a guide roller. The additional guide carriage with the guide roller can be designed analogously or identically to the guide carriage with the guide roller already described. Furthermore, the door leaf can be moved or adjusted by means of the two guide carriages. The additional guide carriage with its guide roller can be arranged on the same guide rail or on a separate guide rail. The guide rail or the separate guide rail can be designed accordingly, and the guide roller can be arranged on the separate guide rail as already described in connection with the guide rail.

[0014] Preferably, the two guide carriages that hold the door leaf can be arranged at a predetermined distance from each other. Preferably, the two guide carriages are designed analogously or identically to each other. For example, one of the guide carriages can be arranged at a region of a first end of the narrow side of the door leaf, which extends particularly parallel to the floor element, and the other guide carriage can be arranged at a region of a second end of the narrow side of the door leaf opposite the first end. In other words, the guide carriages can be arranged at opposite ends of the door leaf or the guide rail.

[0015] Advantageously, the guide rail has a rectangular cross-section and is diagonally oriented in a roof-like shape in one of the vertical directions of the sliding door. In other words, the guide rail, which has a rectangular cross-section, can be arranged or oriented in a diamond shape, particularly in the vertical direction of the sliding door. In particular, the guide rail can be configured vertically and diagonally.

[0016] Furthermore, the guide rail has a lowering area, wherein the guide carriage with the at least one guide roller, or the at least one guide roller in the closed position, is arranged in the lowering area. The lowering area refers in particular to an opening, area, or cutout, especially a window cutout, in which the guide roller is lowered, i.e., lowered from the guide surface or rolling surface of the guide rail. In other words, the guide rail can be recessed at a predetermined area of ​​the running surface. The lowering area can particularly preferably be formed by a trapezoidal cutout in the guide rail, especially in the guide rail elements arranged perpendicular to a first guide rail element and a second guide rail element, and / or by a cutout in the first guide rail element.In particular, the trapezoidal cutout extends perpendicular to the longitudinal direction or in the direction from the first guide rail element, which has the guide surface, to the second guide rail element, which is located opposite it, particularly parallel to it. The cutout or opening in the first guide rail element can be rectangular. Advantageously, the length of the lowering area or trapezoidal cutout or opening of the first guide rail element, particularly in a longitudinal direction of the guide rail, corresponds to a diameter of the guide roller, particularly the bearing roller of the guide roller. In the closed position, the running roller or guide roller of the guide carriage belonging to the running surface moves into this recess and thus lowers the door leaf towards the frame and / or the floor element or the floor surface.The lowering action causes the door leaf to slide into a lowering plane, preferably against the frame or frame or a frame member and / or the floor element.

[0017] Preferably, the guide rail has a further lowering section, wherein at least one guide roller of the further guide carriage is arranged in this further lowering section in the closed position. In other words, the guide rail can be recessed at a predetermined area of ​​the running surface. In the closed position, the roller or guide roller of the further guide carriage belonging to the running surface moves into this further recess and thus lowers the door leaf towards the frame and / or the floor element or the floor surface. Through this further lowering, the door leaf slides, in particular, into the lowering plane, preferably against the frame or frame jamb or a frame mullion and / or the floor element.

[0018] Preferably, the recess and the further recess on the guide rail are arranged at a predetermined distance from each other. In the closed position, the guide roller of the guide carriage is located in the recess, and the guide roller of the further guide carriage is located in the further recess. A lowering plane is formed by each recess or lowering area. Preferably, the recess and the further recess are designed analogously or identically. Furthermore, the lowering plane can be formed by both recesses. Therefore, the guide rail is preferably provided with two lowering planes.

[0019] Furthermore, the guide device includes a lowering element, which is in particular movable or movably mounted, and which is arranged in the lowering area of ​​the guide rail. In the closed position, the lowering element can be lowered by the guide carriage with the at least one guide roller, or the at least one guide roller can be lowered in the lowering area. The lowering element preferably lowers perpendicular or orthogonally to the rolling surface or guide surface of the guide rail. The lowering area is formed by at least one opening in at least one guide rail element, which forms the rolling or guide surface of the guide rail, in which the lowering element is arranged. In other words, a cutout for lowering the door leaf is preferably arranged in the guide rail. The lowering element, which can also be referred to as a bridge, is preferably arranged in this cutout.Preferably, the lowering element is designed as a plate or in a plate-like form. Furthermore, the cutout in the guide rail, particularly on the first guide rail element, can enclose the lowering element. If the lowering element is not lowered, it forms the rolling surface together with the guide rail. Particularly preferably, the lowering element has a hat-shaped cross-section. The lowering element, which is arranged in the lowering area, can at least partially abut an underside of the first guide rail element that is opposite the guide surface. A raised section of the lowering element can be arranged in the cutout of the first guide rail element. Furthermore, the thickness of the raised section of the lowering element can be adapted to the thickness of the first guide rail element.The protruding parts of the lowering element, which is shaped particularly like a hat in cross-section, can rest against the underside of the first guide rail element. The lowering element allows for a particularly simple, safe, and reliable lowering of the door leaf.

[0020] Furthermore, the guide device includes a force storage element, in particular a spring assembly, which is configured to movably mount the lowering element. In other words, the guide device includes a pre-tensioned, in particular spring-tensioned, lowering element or a pre-tensioned, in particular spring-tensioned, bridge. The lowering element is specifically arranged or supported on the force storage element, in particular the spring assembly. Preferably, the guide rail has two opposing, in particular parallel, guide rail elements. One of the guide rail elements preferably has the guide or rolling surface. When the lowering element is lowered, it is located, in particular, between the two guide rail elements.Preferably, the energy storage element, in particular the spring device, is arranged between the first guide rail element and the second guide rail element.

[0021] Advantageously, the spring assembly comprises several springs, in particular four, six, or eight springs. It is especially preferred that the spring preload or spring strength of the springs in the assembly be adjustable. The spring is preferably a metallic technical component that can be elastically deformed. Preferably, the springs are designed as helical springs. The spring assembly allows the lowering element to be lowered safely and the degree of lowering to be set in a particularly simple and reliable manner.

[0022] According to an advantageous embodiment, the spring assembly comprises several spring guides, which are configured to hold the springs on the lowering element. In other words, the springs can be held in the bridge by the spring guides. "Spring guides" refers in particular to mechanical elements configured to guide, hold, and / or support springs. A spring guide can be assigned to or associated with a specific spring. In other words, the number of spring guides can correspond to the number of springs in the spring assembly. Particularly preferably, the spring guides are configured to define a direction of movement for the springs, with each spring being arranged on and / or around a spring guide. The spring guides allow the springs to be held and guided in a particularly simple and reliable manner.

[0023] An advantageous embodiment provides that the guide device is configured to move or lower the door leaf in the closed position towards a floor area and / or a frame enclosing the passageway. In other words, the guide device is preferably configured to lower the door leaf simultaneously against the floor and the frame. This allows the guide device to move or lower the door leaf in at least two spatial directions, particularly horizontally and / or vertically, and especially diagonally. This offers the advantage that the passageway of the sliding door can be closed particularly reliably and securely.

[0024] An advantageous embodiment provides that the sliding door includes a sealing device, wherein, in the closed position of the door leaf, the sealing device is arranged between at least one frame enclosing the passage area or at least one frame member of the frame.

[0025] Additionally or alternatively, the sealing device can be arranged between a floor element framing the passage area and the door leaf, particularly in a sealing manner. "Floor element" refers in particular to a section of a floor or subfloor. The frame of the sliding door and the floor element preferably frame or define the passage area. To seal the sliding door tightly in the closed position, the frame or frame jamb, the sealing device, and the door leaf, and / or the floor element, the sealing device, and the door leaf, are arranged, in particular consecutively, adjacent to or abutting each other. For a particularly tight seal, the sealing device preferably rests against a surface of the door leaf, a surface of the floor element, and a surface of the frame.Preferably, the self-weight of the door leaf or the weight of the door leaf drives the door leaf into the closed position or end position against the surrounding sealing device, whereby the sealing device has a damping effect due to its flexibility.

[0026] Advantageously, the sealing device comprises a first sealing element, wherein the first sealing element is arranged at least on one side of the door leaf facing the frame, either on the door leaf itself, on the frame enclosing the passage area, or on a frame member of the frame. "Frame" refers in particular to a door frame or frame of the sliding door. The first sealing element can therefore be arranged either on the frame or a frame member, or on at least one side or surface of the door leaf facing the frame.

[0027] If the first sealing element is arranged on the door leaf, for example, it can be located on a side of the door leaf that faces or is associated with the frame or at least one frame member. In particular, the first sealing element extends parallel to, and especially opposite, the frame or the at least one frame member. Preferably, the first sealing element extends over the entire width of the door leaf's side, particularly between the door leaf's side and a surface of the frame or the at least one frame member facing the door leaf's side. Additionally or alternatively, the first sealing element can also be located on a narrow side of the door leaf, which extends, in particular, perpendicular to the door leaf's side.

[0028] The frame of the sliding door can, in particular, comprise three frame members, two of which—the first and the second frame members—extend vertically in the direction of the sliding door, especially perpendicular to the floor element. The third frame member connects the first and second frame members and extends, in particular, perpendicular to the first and second frame members or parallel to the floor element. Preferably, the floor element abuts the frame or the first and second frame members.

[0029] The first sealing element can be arranged on a surface on the first, second, and / or third frame member facing the door leaf. Alternatively, the first sealing element can be arranged on the narrow side of the door leaf that extends parallel to and faces the first frame member, and / or on the narrow side of the door leaf that extends parallel to and faces the second frame member, and / or on the narrow side of the door leaf that extends parallel to and faces the third frame member. The door leaf can have a total of four narrow sides, with three of these facing the frame and one facing the floor. Preferably, the first sealing element can be arranged circumferentially around the narrow sides of the door leaf.

[0030] Alternatively, the first sealing element can be arranged on the side of the door leaf facing the first, second, and / or third frame member, and extending, in particular, parallel to the first, second, and / or third frame member. The door leaf can have two sides, one of which faces the frame. Preferably, the first sealing element can completely surround or frame the entire side of the door leaf, especially in the area of ​​the first, second, and / or third frame member.

[0031] The first sealing element can be designed as a lip seal or a chamber seal. Furthermore, the first sealing element can be made of a flexible or elastic material.

[0032] An advantageous embodiment provides that the sealing device comprises a second sealing element, wherein the second sealing element is arranged on the door leaf or on the floor element at least along one narrow side of the door leaf facing the floor element. In other words, the second sealing element can be arranged or attached either to the door leaf or to the floor element on the narrow side of the door leaf facing the floor element, particularly between the narrow side facing the floor element and the floor element. If the second sealing element is arranged or attached to the floor element, for example, it can also be referred to as a floor seal. In particular, the second sealing element extends at least partially, i.e., completely or partially, in the direction of the narrow side or the floor element.Preferably, the second sealing element extends between the bottom element and the narrow side of the door leaf facing the bottom element, from the first frame member to the opposite second frame member. Like the first sealing element, the second sealing element can be designed as a lip seal or a chamber seal. Furthermore, the second sealing element can be made of a flexible or elastic material.

[0033] For example, the sealing device can be arranged with the first and second sealing elements alternating. For instance, the second sealing element could be located on the narrow side of the door leaf facing the bottom element, and the first sealing element on a surface of the first frame member facing the door leaf. Other alternating arrangements are also conceivable. For example, the second sealing element could be located on the bottom element, and the first sealing element on a surface facing the frame, such as the third frame member which extends parallel to the bottom element, particularly the wide side of the door leaf.The term "alternating" means in particular that the first sealing element and / or the second sealing element are arranged alternately on the door leaf, especially on a narrow side of the door leaf and / or on a wide or narrow side of the door leaf and / or on the bottom element and / or the frame and / or the frame member of the frame. It is particularly preferred that the first sealing element is arranged around the perimeter of the frame, especially on a surface facing the door leaf, and the second sealing element is arranged on the bottom element, especially as a bottom seal.

[0034] The sealing device can thus completely encircle the door leaf by means of the first and second sealing elements. Particularly preferably, the door leaf can be provided with a circumferential lip or chamber seal, which is composed in particular of the first and second sealing elements, so that the guide device moves the door leaf into the closed position in a tightly closing manner.

[0035] A particularly preferred embodiment provides that the guide device allows the door leaf with the sealing device to be moved or shifted in a longitudinal or lateral direction, or in a sliding direction of the door leaf (which can also be referred to as an x-direction), and / or in a vertical direction of the door leaf (which can also be referred to as a z-direction), and / or in a transverse direction of the door leaf (which can also be referred to as a y-direction). The longitudinal, vertical, and transverse directions of the door leaf or sliding door are, in particular, perpendicular to each other or orthogonal to each other.

[0036] For example, the door leaf is moved into the closed or shut position by means of the guide mechanism, in which the door leaf is lowered three-dimensionally – in the x, y, and z directions – particularly by its own weight or the weight of the door leaf itself. The door leaf can slide against the frame and the bottom element or the floor along a three-dimensional lowering plane. The weight of the door leaf can then drive it into the closed or final position against the sealing device, particularly the perimeter seal. The sealing device can provide damping due to its flexibility.

[0037] Advantageously, the door leaf, particularly by means of the guide mechanism, is lowered against the first and second sealing elements in the closed position. Specifically, the door leaf is simultaneously lowered and pressed against the bottom seal and the frame seal. This results in the advantage that the passage area of ​​the sliding door can be closed particularly reliably and securely.

[0038] Preferably, the sliding door may have at least one damping element designed to cushion the door leaf as it lowers. Particularly preferably, the sliding door may have several damping elements. Advantageously, the at least one damping element is designed to cushion the movement of the door leaf against the surrounding seal as it moves into its final position.

[0039] By such an arrangement of the first sealing element and / or the second sealing element of the sealing device, the first sealing element and / or the second sealing element of the sealing device are subjected to a particularly low shear stress, especially during the closing and / or opening process.

[0040] Advantageously, during an opening or closing process of the sliding door, i.e., when the door leaf is moved from an open position to a closed position or vice versa, there is no contact between the seal and any surface, since the door leaf is lifted or free-running.

[0041] Another advantageous embodiment provides that the guide device comprises a first retaining element, which is configured to hold the guide rail and / or the at least one guide roller or the guide carriage, and a second retaining element, which is configured to hold the door leaf. In particular, an axle of the at least one guide roller is received in the second retaining element. The second retaining element is particularly preferably designed as a roller holder, which is configured to hold the at least one guide roller. In other words, the axle of the at least one guide roller can be fixed in the second retaining element designed as a roller holder. Preferably, the first retaining element is designed as a wall bracket. Furthermore, the first retaining element and the second retaining element can be arranged to be movable relative to each other for adjusting the guide device.Furthermore, the first retaining element and the second retaining element can be moved or displaced, particularly linearly, towards or away from each other. Most preferably, the door leaf can be suspended from the guide carriage in a way that allows it to be adjusted in the z, x, and y directions. In particular, the second retaining element forms part of or is a component of the guide carriage.

[0042] According to the invention, the sliding door has a locking device movable between a locking position and a release position, which is designed to block the lifting of the sealingly lowered door leaf in the locking position.

[0043] It is preferred that the blocking device be movable by sliding the door leaf along the guide device.

[0044] It is preferred that the blocking device has a movable follower element designed to be moved along with the door leaf when it is moved into the closed position, in order to move the blocking device into the blocking position.

[0045] It is preferred that the locking device has a movable locking element which, in the locking position, holds the guide carriage or the part of the guide carriage lowered into the lowering area in the lowering area.

[0046] It is preferred that the locking device has a holder or guide for storing one or more elements of the locking device that are movable between the locking position and the release position.

[0047] According to the invention, the moving element of the locking device is designed as a rocker arm. This can be single-armed or double-armed. One section of the rocker arm, e.g., a first arm, serves as a driver, and another section, e.g., a second arm, serves as the locking element.

[0048] According to the invention, the blocking device therefore has a rocker, in particular a roller rocker, which is designed to receive the at least one guide roller, wherein the rocker is movable about a pivot point, in particular an eccentrically mounted one.

[0049] Furthermore, the locking device has a rocker arm holder which is designed to hold the rocker arm.

[0050] It is preferred that the rocker is further configured to press the at least one guide roller against the lowering element for lowering and / or to lock against levering out the at least one guide roller arranged in the lowering area.

[0051] It is preferred that the locking device is held in the release position by at least one energy storage device or a spring element, in particular a leaf spring, and / or a fastening element, which is in particular designed as a cam.

[0052] In one embodiment, the guide device comprises a rocker, in particular a roller rocker, which is configured to receive and / or hold the at least one guide roller. In other words, the guide device can have a rocker, in particular a roller rocker, wherein the at least one guide roller can be arranged on or in the rocker. Furthermore, the rocker is movable about a pivot point, in particular an eccentrically mounted one. The rocker is preferably mounted eccentrically. In particular, the rocker is arranged outside the pivot point or center of rotation of the guide roller. The rocker can also be referred to as a fork, in particular a rocker fork. Furthermore, the rocker preferably has two lever arms—a first lever arm and a second lever arm—in which the lever arms extend away from the pivot point. The lever arms are preferably curved, thereby in particular the rocker being curved.The curved design of the lever arms allows them to receive the guide roller and / or bear against it, at least partially. In particular, the inner radius or diameter of the lever arms is adapted to the circumference or outer diameter of the guide roller, especially the support roller. Furthermore, the first lever arm is preferably longer than the second. The rocker mechanism allows for particularly precise control of the lowering process when the door leaf is closed.

[0053] The rocker and the spring-loaded lowering element form a device that locks the door leaf against being pried open, especially in the closed position. The sliding door is lowerable and includes a device or mechanism to prevent it from being pried open.

[0054] Furthermore, the guide device includes a rocker arm holder designed to hold or support the rocker arm. The rocker arm holder can preferably be designed as a plate, particularly a mounting plate. The rocker arm holder can be arranged on the first or second retaining element. The rocker arm holder has the advantage of allowing the rocker arm to be held particularly easily and reliably.

[0055] Another advantageous embodiment provides that the rocker is further equipped to press the at least one guide roller against the lowering element for lowering and / or to lock against levering out the at least one guide roller arranged in the lowering area.

[0056] The following is an example of a functional sequence for lowering and / or raising the door leaf using the guide device. The door leaf moves along the guide rail (which is often angled) into a closed position via the guide roller(s). A force is applied horizontally, particularly parallel to the guide rail or in the direction of a main extension of the guide rail, through the door leaf. The rocker arm or fork is in the receiving position for the guide roller or support roller, specifically in a position where the guide roller is not yet engaged or positioned within the rocker arm. As the door leaf continues to move, the rocker arm, with its lever arms of varying lengths, engages the guide roller or support roller and, via the eccentrically mounted pivot point, presses the support roller or guide roller against the spring-loaded lowering element or spring-loaded bridge to lower the door.The springs are designed to counterbalance the weight of the door leaf. Due to the eccentric arrangement of the rocker's pivot point relative to the axis of the guide or support roller, a dead center is reached and / or, in the event of a vertical force, particularly perpendicular to the guide surface, the mechanism is locked against upward displacement and / or movement into the open position or in the opening direction of the door leaf. A horizontal force and / or the opening of a bolt fold on the lock pushes the lowering element downwards past the dead center. In mechanics, a dead center is defined as a lever mechanism where the connecting joints and / or the acting force vectors lie on a common line. In this case, the applied force is transferred to the holding point of the mechanism; movement of the lever is impossible without external force.Only a force acting perpendicular to the main axis of this mechanism can change this state. The rocker opens via the short lever arm, and the guide roller or support roller is lifted onto the guide rail by the rocker, its springs, and the horizontal force, particularly the horizontal force acting from the right or left, for the opening movement. The lowering element closes the guide rail at the top.

[0057] Preferably, the rocker arm is held in the open or closed position by at least one spring element, in particular a leaf spring, and / or a fastening element. Preferably, the rocker arm can be arranged or held on the guide roller in the open or closed position by at least one spring element, in particular a leaf spring, and / or a fastening element. The fastening element can, for example, be designed as a cam. For example, the eccentrically mounted fork is arranged on or attached to the mounting plate and is held in the open or closed position against a leaf spring by a cam.

[0058] Advantageously, the rocker has a first rocker roller at a first end, particularly at an end of the first lever arm, and a second rocker roller at a second end, particularly at an end of the second lever arm. In other words, a rocker roller is preferably arranged or provided at each end of the rocker. The rocker rollers offer the advantage that the rocker can be moved particularly easily around or on the at least one guide roller.

[0059] Preferably, the sliding door has a locking device located on a narrow side of the door leaf, particularly on the lock-side end face of the door leaf. As a partition wall, the sliding door can offer a certain degree of burglary protection through this locking mechanism and, in particular, can also provide fire protection.

[0060] Advantageously, the door leaf has a guide groove, and the sliding door includes a guide element that engages in the guide groove. Preferably, the guide groove is located on the narrow side of the door leaf facing the floor. Preferably, the guide groove extends at least partially, i.e., completely or partially, along the length of the narrow side of the door leaf. In other words, a guide groove can be provided in the lower narrow side of the door leaf facing the floor, in which at least one guide block is arranged as a guide element. Particularly preferably, the sliding door has two guide elements, one located in a region of a first end of the narrow side of the door leaf and the other in a region of a second end of the door leaf opposite the first end of the narrow side.A guide element, each designed as a guide block, can be adjustable and positioned in the guide groove on the narrow side of the door leaf on both sides. This guide element is specifically designed for stable floor guidance of the door leaf. The guide groove is adapted to the shape of the guide element.

[0061] In particular, the guide element is wedge-shaped or rectangular. The guide element is preferably designed to limit the range of motion of the door leaf, especially in the area of ​​the guide groove. This allows for the restriction or limitation of movement of the door leaf in the transverse direction of the door leaf or sliding door, i.e., in the z-direction.

[0062] According to an advantageous embodiment, the sliding door includes a lifting device designed to raise the guide carriage or guide roller from the lowering position. Advantageously, the lifting device comprises a lever handle fitting with an eccentric mechanism. A lockable hook fitting, particularly for burglar protection, can be combined with or provided for the lever handle fitting or lever fitting. The opening process of the sliding door is ensured by the door leaf being moved out of the closed position. This involves lifting the door leaf from the lowering position, specifically above the lowering plane, onto a rolling plane along which the at least one guide roller is moved. This process can be accomplished via the lever handle fitting with the eccentric mechanism, which is pressed against a closing side of the frame.This results in an acceptable opening force through a corresponding lever ratio, which can be further reduced, in particular, by an inclined plane on the guide fitting.

These show: Fig. 1 A schematic representation of a sliding door in a closed position, wherein one door leaf of the sliding door closes off a passageway, in a front view; Fig. 2 a schematic representation of a section of the sliding door of Fig. 1 with a guide device for moving a door leaf of the sliding door in a sectional view; Fig. 3 a schematic representation of a section of the sliding door with an alternative design of the guide device for moving the door leaf of the sliding door in a sectional view; Fig. 4 A schematic representation of a section of the sliding door with the guide mechanism of Fig. 3 when the door leaf moves into a closed position in a further sectional view; Fig. 5 a schematic representation of a section of the sliding door with the guide mechanism of Fig. 3 in the closed position of the door leaf; and Fig. 6 A schematic representation of a section of the sliding door with the guide mechanism of Fig. 3 when the door leaf moves into an open position.

[0064] The exemplary embodiments described below are preferred embodiments of the invention. In these exemplary embodiments, the described components each represent individual features of the invention that can be considered independently of one another. Each of these features further develops the invention independently and can therefore be considered part of the invention individually or in a combination other than that shown. Furthermore, the described embodiments can also be supplemented by other features of the invention already described.

[0065] In the figures, functionally identical elements are each provided with the same reference symbols.

[0066] Fig. 1 to Fig. Figure 6 shows a schematic representation of a sliding door 1. The sliding door 1 is arranged on a predetermined area of ​​a wall 2, in particular of a building or a room. The wall 2 has a passageway 3 or a wall opening. The sliding door 1 has a frame 4 and a door leaf 6. The passageway 3 is framed, bordered, or delimited by a floor element 5 and the frame 4. The sliding door 1 is designed to close the passageway 3 with the frame 4 by means of the door leaf 6 in a closed position. Particularly preferably, the door leaf 1 is arranged at least partially or completely in or on the passageway 3 in the closed position, in particular to close the passageway 3. In the closed position, the sliding door 1 separates two rooms from each other.In other words, the sliding door 1 with the door leaf 6 closes off the passageway 3 or the wall opening with the frame 4 in such a way as to separate two rooms from each other.

[0067] Furthermore, the sliding door 1 has a guide device 7, 7' which is designed to move the door leaf 6 from an open position to the closed position. Fig. Figure 2 shows an embodiment of the guide device 7 and Fig. 3 another embodiment of the guide device 7'. The guide devices 7 and 7' are designed to be nearly identical or the same and differ in the design and / or arrangement of the first retaining element 32, 32' and the second retaining element 36, 36' as well as the rocker holder 26 with regard to Fig. 2 and Fig. 3 will be discussed in more detail. In particular, the door leaf 6 is slidably held on the guide device 7, 7'. The door leaf 6 can be moved in a sliding direction, which extends in particular in a longitudinal or lateral direction of the sliding door 1. The door leaf 6 can be moved until it closes the passage area 3 or abuts the frame 4.

[0068] Furthermore, the sliding door 1 has a sealing device 8, which comprises a first sealing element 9. The sealing device 8 can comprise at least one further sealing element (not shown in the figures). Fig. 2 and Fig. Figure 3 shows only the first sealing element 9. The sealing device 8 is designed to seal the sliding door 1, in particular the passage area 3, when the door leaf 6 is closed. The first sealing element 9 and / or at least one further sealing element are arranged on the door leaf 6. The first sealing element 9 and / or at least one further sealing element can be designed as a chamber seal or a lip seal. Furthermore, the first sealing element 9 and / or at least one further sealing element can be made of an elastic and / or flexible material. The first sealing element 9 and / or at least one further sealing element can also be fixed or held on the door leaf 6. For this purpose, the door leaf 6 can have a retaining groove for the first sealing element 9 and / or each further sealing element.The first sealing element 9 can be partially received in the retaining groove provided for the first sealing element 9 and thereby held or fixed to the door leaf 6. Alternatively, the first sealing element 9 can also be glued or otherwise fixed to the door leaf 6.

[0069] The first sealing element 9 is arranged on the door leaf 6 at least on one side 10 of the door leaf 6 facing the frame 4 or the passage area 3. Alternatively, the first sealing element 9 can also be arranged on a surface of the frame 4 facing the side 10 of the door leaf 6. The first sealing element 9 can extend at least partially, i.e., completely or partially, in a width direction and / or height direction of the sliding door 1, in particular along a length of the side 10 or surface, especially the surface area, of the door leaf 6. Preferably, the first sealing element 9 is arranged as shown in Fig. 2 and Fig. 3, as can be seen, is arranged on one side of the door leaf 6. The first sealing element 9 extends along the side of the door leaf opposite and / or parallel to a surface of a frame member of the frame 4. The frame member of the frame 4 in Fig. 2 and Fig. 3 refers to the frame member, which extends perpendicularly to the floor element 5. The frame 4 and / or the frame member can also be referred to as the wall opening trim. Alternatively, the first sealing element 9 can be arranged as a circumferential seal on the door leaf 6 or on the passage area 3, in particular the wall opening trim. Additionally or alternatively, the first sealing element 9 can also be arranged on a narrow side or end face of the door leaf 6, which faces the frame 4 or at least a frame member of the frame 4. For example, the first sealing element 9 can be arranged on a lock-side end face of the door leaf 6, which faces the frame 4.

[0070] The at least one further sealing element can be arranged on the door leaf 6 at least along a narrow side 11 facing the floor element 5. In particular, the at least one further sealing element extends at least partially, i.e., completely or partially, in the direction of the longitudinal direction or sliding direction of the sliding door 1, in particular along a length of the narrow side 11.

[0071] Furthermore, the sliding door 1 has the guide device 7, 7', which is designed to keep the door leaf 6 movable. The guide device 7, 7' allows the door leaf 6 to be moved linearly in the x-direction. The door leaf 6 can be moved from the open position, in which the passage area 3 is clear, to the closed position, in which the door leaf 6 closes the passage area 3. The door leaf 6 can also be moved automatically or manually.

[0072] For moving the door leaf 6, the guide device 7, 7' has a guide rail 12 and a guide carriage 13. The guide rail 12 is preferably designed as a profile rail. In Fig. 2 and Fig. 3. The guide rail 12 is identical, i.e., the same. The door leaf 6 can be moved along the guide rail 12, particularly in the x-direction, by means of the guide carriage 13. The guide rail 12 has a rectangular cross-section. Furthermore, the guide rail 12 is oriented diagonally, particularly in a diamond shape, in the vertical direction of the sliding door 1. It is especially preferred that the guide rail 12 is arranged or oriented vertically and diagonally. In other words, the guide rail 12 is arranged at an angle.

[0073] The guide vehicle 13 has a guide roller 14. In Fig. 2 and Fig. The guide roller 14 is identical, i.e., designed the same way. The guide roller 14 rolls along the guide rail 12. The guide roller 14 thus rolls over the square guide rail 12, which is positioned at an angle. "Guide roller" refers in particular to a roller or wheel that is rotatably mounted about an axis. The guide roller 14 can also be called a running roller. The guide roller 14 is arranged on a guide surface 15, which can also be called a rolling surface. The guide roller 14 is designed as a flanged roller. The flanged roller has a projection 17a or shoulder at one end 16 that extends, in particular radially, around the roller. With the aid of the projection 17a, the flanged roller can be positioned against a surface 18 of the guide rail, which is arranged, in particular, perpendicular to the rolling surface 15, and in particular flush with it. The projection 17a is round or circular.The extension 17a provides the guide roller 14 with an edge such that a surface of the guide roller 14 rests on the guide surface 15, and a surface, in particular of the extension 17a, abuts a surface 18 of the guide rail 12, which extends perpendicularly to and / or adjoins the guide surface 15. Furthermore, the guide roller 14 has a support roller 17b, which is arranged on or rests upon the guide surface 15. The guide roller 14 thus comprises the support roller 17b and the extension 17a, which extends around the support roller 17b and abuts the surface 18 of the guide rail 12 arranged perpendicular to the guide surface 15.

[0074] By means of the guide device 7, 7', the guide carriage 13 with the door leaf 6 is moved over or along the guide rail 12, whereby the guide carriage 13 lowers itself in the closed position of the door leaf 6. For this purpose, the guide rail 12 has, as shown in the figures Fig. 4 to Fig. As can be seen from section 6, there is a lowering range of 19.

[0075] In the closed position, the guide roller 14, in particular the guide carriage 13 with the guide roller 14, is arranged in the lowering area 19. The lowering area 19 is designed as an opening, a gap, or a cutout in the guide rail 12. In the lowering area 19, the guide roller 14, in particular the guide carriage 13 with the guide roller 14, is lowered from the guide surface 15. Fig. 4 and Fig. 6 the guide roller 14, in particular the support roller 17b, is located on or at the level of the guide surface 15. In Fig. 5 is the leading role 14 in the reduction area 19 reduced. In particular, it shows Fig. 5. The guide roller 14, in particular the collar roller, is secured in the lowered position on the bridge. The guide rail 12 has at least two guide rail elements 20, 21 – the first guide rail element 20 and the second guide rail element 21. The guide rail 12 has a total of four adjacent guide rail elements, in particular forming a rectangle orthogonally or perpendicularly. The two guide rail elements 20, 21 are arranged parallel to each other at a predetermined distance. The first guide rail element 20 has the guide surface 15, wherein the guide surface 15 forms the surface of the first guide rail element 20 facing away from the second guide rail element 21.The lowering area 19 is formed by a trapezoidal cutout 19a in the guide rail 12, particularly on the guide rail elements arranged perpendicular to the first guide rail element 20 and the second guide rail element 21, and / or a cutout in the first guide rail element 20. In other words, the guide rail 12 can have a trapezoidal cutout in the lowering area 19. In particular, the trapezoidal cutout extends perpendicular to the longitudinal direction or in the direction from a first guide rail element 20, which has the guide surface 15, to the second guide rail element 21, which is opposite, and in particular parallel to, the first guide rail element 20. The cutout or opening in the first guide rail element 21 can be rectangular.In particular, the length of the lowering area or trapezoidal cutout or cutout of the first guide rail element, especially in a longitudinal direction of the guide rail, corresponds to a diameter of the support roller17b.

[0076] In the closed position, the guide roller 14 of the guide carriage 13, belonging to the guide surface 15 or running surface, moves into this recess, i.e., the lowering area 19, and thus lowers the door leaf 6 towards the frame 4 and / or the floor element 5 or the floor surface. The door leaf 3 slides through the lowering area 19, in particular into a lowering plane, as is the case in Fig. 5 is shown.

[0077] To lower the guide roller 14 in the lowering area 19, the guide device 7, 7' has a lowering element 22. In other words, a cutout for lowering the door leaf 6 is arranged in the guide rail 12. The lowering element 22, which can also be referred to as a bridge, is arranged in the cutout. Accordingly, the lowering area 19 can also be referred to as a cutout, in particular a window cutout, in the bridge area. The lowering element 22 is movably mounted. The lowering element 22 is arranged in the opening forming the lowering area 19 such that the first guide element 20, in particular the guide surface 15, and a surface of the lowering element 22 form a flat surface when the door leaf 6 is not in the closed position, as is the case in Fig. 4 and Fig. Figure 6 shows the following. In the closed position of the door leaf 6, the lowering element 22 can be lowered in the lowering area 19 by means of at least one guide roller 14. In the closed position, the lowering element 22 is located as shown in Fig. 5 is shown, between the first guide rail element 20 and the second guide rail element 21.

[0078] To lower the lowering element 22, the guide carriage 13, particularly by its own weight, presses the lowering element 22 downwards. In other words, the lowering element 22 is pressed downwards under load, particularly by the guide carriage 13 or the guide roller 14, especially in the direction of the second guide rail element 21. The lowering of the lowering element 22 occurs perpendicular or orthogonal to the rolling surface or guide surface 15 of the guide rail 12.

[0079] How Fig. 2 to Fig. As can be seen in Figure 6, the guide device 7, 7' further comprises a spring assembly 23. The spring assembly 23 is designed to movably mount the lowering element 22. Preferably, the guide device 7, 7' comprises a spring-loaded lowering element 22 or a spring-loaded bridge. In other words, the guide device 7, 7' comprises a spring-adjustable bridge. For this purpose, the spring assembly 23 is arranged between the first guide rail element 20 and the second guide rail element 21. As shown in the figures Fig. 3 to Fig. As can be seen from Figure 6, the spring assembly 23 has several springs 24. Fig. Figure 4 shows the spring assembly with six springs 24. In the figures Fig. 5 and Fig. The spring assembly 23, in particular to avoid obstructing the cutout 19, has two springs 14. Furthermore, the spring preload or spring strength of the springs 24 in the spring assembly 23 is adjustable. Preferably, the multiple springs 24 have a predetermined spring preload. Depending on the spring preload or spring strength of the springs 24, a degree of lowering can be set. In particular, the spring preload of the springs 24 is set such that the door leaf 6 is lowered and pressed against the frame seal and bottom seal – first sealing element 9 and further sealing element. The springs 24 can also be set to compensate for the weight of the door leaf 6. Preferably, the guide assembly 14 has two lowering zones in the longitudinal direction and correspondingly two lowering elements and two spring assemblies, which are identical to each other.Particularly preferably, the guide rail 12 has two spring-loaded bridges located in the longitudinal direction, which lower themselves downwards under load and / or forced guidance.

[0080] Furthermore, the spring assembly 23 has several spring guides 24a. The spring guides 24a are designed to hold the springs 24 on the lowering element 22. In other words, the springs 24 can be held in the bridge by the spring guides 24a. "Spring guides" refers specifically to mechanical elements designed to guide the springs 24. A spring guide 24a can be assigned to or associated with a spring 24. The spring guides 24a can be designed to define a direction of movement for the springs 24. As shown in the figures... Fig. 2 to Fig. As can be seen from Figure 6, a spring 24 is arranged on a spring guide 24a and / or around a spring guide 24a.

[0081] Furthermore, the guide device 7 includes a rocker 25 as a locking device. The rocker 25 is designed as a roller rocker. The rocker 25 can also be referred to as a fork. The rocker 25 is arranged on the guide roller 14, particularly in the closed position. Furthermore, the rocker 25 is mounted eccentrically. In particular, the rocker 25 is arranged outside the pivot point or center of rotation of the guide roller 14. The rocker 25 allows for particularly good control of the lowering process in the closed position of the door leaf 6. The guide device 7 also preferably includes a rocker holder 26, which is designed to hold or support the rocker 25. The eccentrically mounted rocker 25 is arranged on the rocker holder 26. The rocker holder 26 can also be referred to as a mounting plate.The rocker 25 is held by at least one spring element 27, which is in particular designed as a leaf spring, and / or at least one fastening element 28. According to the embodiment in . Fig. 3 to Fig. 6 The rocker 25 is held by means of a fastening element 28 designed as a cam. In particular, the rocker 25 is held against a leaf spring, especially in the open position and / or closed position, by means of a cam.

[0082] Finally, the rocker 25 comprises two rocker rollers 29, 30. The first rocker roller 29 is arranged at one end of the rocker 25 and the second rocker roller 30 at the other end of the rocker 25. In other words, a rocker roller or fork roller is provided at each end of the rocker or fork. The rocker 25 has a boomerang-shaped or quarter-circle, and in particular a curved, shape. An inner radius of the rocker 25 is adapted to an outer radius of the guide roller 14, in particular the support roller 17b. The rocker 25 rests against the guide roller 14. The rocker 25 rotates or pivots about its pivot point 31. Furthermore, the rocker 25 has two lever arms – a first lever arm 25a and a second lever arm 25b – which extend away from a pivot point 31. The lever arms 25a, 25b are preferably curved.Due to their curved design, the lever arms 25a, 25b are configured to receive the guide roller 14, in particular the support roller 17b, and / or to bear against the guide roller 14, at least partially. Specifically, an inner radius or diameter of the lever arms 25a, 25b is adapted to a circumference or outer diameter of the guide roller 14, in particular the support roller 17b. Furthermore, the first lever arm 25a is longer than the second lever arm 25b. The lever arms 25a, 25b merge seamlessly into one another.

[0083] Furthermore, the rocker 25 has a first rocker roller 29 at a first end, in particular at an end of the first lever arm 25a, and a second rocker roller 30 at a second end, in particular at an end of the second lever arm 25b. In other words, a rocker roller 29, 30 is preferably arranged or provided at each end of the rocker.

[0084] The following describes one example in more detail: The guide carriage 14, equipped with a flanged roller, runs along the vertically diagonally arranged guide rail 12. The sliding door 1 has two guide carriages 14 arranged at opposite ends. A cutout or lowering section 19, designed for lowering the door leaf 6, is arranged in the guide rail 12. An adjustable, spring-loaded bridge or spring-loaded lowering element 22 is located within this section. When the flanged roller moves onto this bridge, it is simultaneously pressed downwards, particularly in the direction of gravity, by the eccentrically mounted roller rocker 25. In other words, the flanged roller is inserted into the rocker and pressed down by the roller rocker, which is eccentrically mounted. The roller rocker 25 is held in place, particularly in the closed or closed position, by the leaf spring element 27 and the cam 28, which are fixed in position.The door leaf 6 has lowered along with the carriage 13. This secures the door leaf 6 against being pried open. In other words, the mechanism with the lowering element 22 provides anti-levering protection. If the door leaf 6 is subsequently opened, particularly horizontally, the roller rocker 25 disengages and releases the roller. The spring-loaded bridge then releases the roller to travel on the guide rail 12.

[0085] In relation to Fig. 5 and Fig. Section 6 below explains the opening and closing processes in more detail.

[0086] The door leaf 6 moves into a closed position via the guide roller 14 over the guide rail 12, which is in particular angled. A force is applied horizontally, in particular parallel to the guide rail 12 or in the direction of a main extension of the guide rail 12, via the door leaf 6. The rocker 25 or fork is in Fig. 6 in receiving position for the guide roller 14 or support roller 17b. By continuing to move the door leaf 6 towards the rocker 25, the rocker 25 with the differently lengthened lever arms 25a, 25b picks up the guide roller 14 or support roller 17b and, via the eccentrically mounted pivot point 31, presses the support roller 17b or guide roller 14 against the spring-loaded lowering element 22 or the spring-loaded bridge for lowering. In Fig. 5 The guide roller 14 or the guide carriage is located in the lowering position 19. The adjusted springs 24 are designed to compensate for the weight of the door leaf 6. Due to the eccentric arrangement of the pivot point 31 of the rocker 25 relative to an axis A of the guide roller 14 or the support roller 17b, a dead center is exceeded, and in the event of a vertical force or vertical action, in particular a vertical force acting from above or below, especially perpendicular to the guide surface 15 or in the direction from the first guide rail element 20 to the second guide rail element 21, it is locked upwards against being pried open and / or moved into the open position or in the opening direction of the door leaf 6.By applying a horizontal force, particularly parallel to the guide surface 15, and opening a locking lug on the lock, the lowering element 22 is pushed downwards past its dead center, particularly perpendicular to the guide surface or in the direction from the first guide rail element 20 to the second guide rail element 21. The rocker arm 25 opens via the short lever arm, i.e., the second lever arm 25b, and the guide roller 14 or support roller 17b is lifted by the rocker arm 25 with its springs 24 and the horizontal force onto the guide rail 12 for the opening movement. The lowering element 22 then closes the guide rail 12 again. Upon opening, the door leaf 6 lifts away from the passage area 3 or the wall opening, particularly with the seal.

[0087] How Fig. As can be seen further in Figure 2, the guide rail 12 of the guide device 7 is held by a first retaining element 32. In particular, the guide rail 12 and / or the first retaining element 32 is attached to the wall 2 above the passage area 3. The first retaining element 32 can also be referred to as a wall bracket. The rocker bracket 26 is also arranged or held on the first retaining element 32. The first retaining element 32 is preferably designed as a hook, and more preferably as a wall hook. In other words, the guide device 7 can be attached to the wall hook. The first retaining element 32 is divided into three retaining element sections. The first retaining element 32 is formed in one piece. The first retaining element section 33 is arranged on the wall 2 and extends along a wall surface of the wall 2. The second retaining element section 34 is arranged on the first retaining element section 33.The second retaining element section 34 is arranged or aligned at a predetermined angle to the first retaining element section 33. Particularly preferably, the second retaining element section 34 is arranged or aligned at a predetermined angle of less than 180° to the first retaining element section 38. Finally, the first retaining element 32 has the third retaining element section 35, which adjoins the second retaining element section 34. The third retaining element section 35 is oriented perpendicular or orthogonal to the second retaining element section 34. The guide rail 12 rests against the second retaining element section 34 and the third retaining element section 35. In other words, the guide rail 12 is held by the second retaining element section 34 and the third retaining element section 35. The first retaining element 32 is preferably made of metal or sheet metal.

[0088] Furthermore, the guide device 7 has a second retaining element 36. The second retaining element 36 can also be referred to as a roller holder. The axis A of the guide roller 14 is attached to or arranged on the roller holder. The second retaining element 36 can be arranged on a hub bearing 37 of the guide device 7. The second retaining element 36 is designed as a hook or an angle. The second retaining element 36 has a retaining element section 38 and a further retaining element section 39. The retaining element section 38 and the further retaining element section 39 are arranged perpendicular to each other. The door leaf 6 is arranged on a retaining surface of the further retaining element section 39 facing away from the guide rail 12 in the further retaining element section 39 of the second retaining element 36, which extends perpendicularly to the wall 2.Furthermore, the first retaining element 32 and the second retaining element 36 are arranged to be movable relative to each other for adjusting the guide device 7. In other words, the retaining elements 32 and 36 are adjustable. In particular, the first retaining element 32 and the second retaining element 36 can be moved away from or towards each other in the vertical and / or horizontal or transverse direction, especially in the z-direction. Alternatively, only the second retaining element 36 can be moved accordingly. The guide carriage 13, which is arranged at each end of the door leaf, is preferably mounted above the adjustable door leaf holder – the first retaining element 32 and the second retaining element 36.

[0089] How Fig.As can be seen further in Figure 3, the guide rail 12 of the further guide device 7' is held by a first retaining element 32' of the further guide device 7'. In particular, the guide rail 12 and / or the first retaining element 32' is attached to the wall 2 above the passage area 3.
