SLIDING DOOR ARRANGEMENT

Description

[0001] The invention relates to a sliding door arrangement with a stationary frame and with a leaf of a door, a window or the like that can be moved relative to the frame along a displacement plane, and with a drive comprising at least one carriage carrying the leaf and a guide unit.

[0002] Sliding doors, especially parallel sliding doors (parallel tilt and slide doors and / or parallel sliding doors), require a force applied by the user to both open and retract the extension arms, especially since the leaf must be moved between a closed position and an extended position to allow the leaf to slide along the sliding plane. If the applied force is too low, leaks may occur when closing the sliding door assembly.

[0003] Another problem with sliding doors is that the position of the leaf relative to the frame is not always adjusted with sufficient precision during installation, meaning that long-term, low-wear operation cannot be guaranteed. Another disadvantage is that the leaves of conventional sliding doors often seal inadequately against the frame when closed, for example, when exposed to wind loads, allowing moisture and cold to penetrate the building. This is unfavorable from an energy perspective.

[0004] DE 26 33 369 A1 discloses a sliding door arrangement in which a leaf can be moved into its open position by pivoting control discs. By turning an eccentric, the contact pressure of the leaf in the closed state can be changed.

[0005] DE 37 21 146 A1 discloses a sliding door arrangement in which a sliding door can be displaced into an opening position by means of an activatable seal along an opening axis oriented perpendicular to the sliding door.

[0006] The invention is based on the object of providing a permanently reliable and energetically favorable sliding door arrangement with the simplest possible construction.

[0007] The invention solves this problem by a sliding door arrangement having the features of claim 1.

[0008] The sliding door arrangement comprises a (stationary) frame (fixed frame) and a leaf of a door, a window or the like which is displaceable relative to the frame along a displacement axis (z) or a displacement plane (yz), and a drive comprising at least one carriage carrying the leaf and at least one guide unit guiding the leaf.

[0009] The sliding door arrangement is characterized in that the leaf is movable along a projection axis (x) relative to the frame between a projection position and a pressure position, wherein the leaf is released in the projection position for displacement along the displacement axis (z) or the displacement plane (yz), wherein the carriage and / or the guide unit has a pressure adjustment device with an adjusting element, by means of which the position of a bearing element of the carriage and / or of a bearing element of the guide unit can be adjusted along the projection axis (x) and relative to a roller arrangement of the carriage that is stationary with respect to the projection axis (x) and / or relative to a guide arrangement of the guide unit that is stationary with respect to the projection axis (x).

[0010] This enables reliable operation of the sliding door arrangement using simple design means, as the release of the movement of the sash along the movement plane (yz) to open the sash is made possible by simply transferring, i.e. sliding, the sash along the extension axis (x) from the pressure position into the extension position. Preferably, just a movement of the sash along the extension axis (x) is sufficient to transfer the sash into the extension position, so that no stroke in the direction of a vertical axis or lifting axis (y) and therefore no lifting device and corresponding application of force by the user is required. In other words, the sash is moved when a handle used for actuation, e.g.A handle, from a closed position, in which the sash is in the closed position, to an open position, in which the sash is in the extended position, is spaced from the frame by a specific distance along the extension axis (x). It is preferably sufficient to space the sash from the frame by only a small distance, in particular a few millimeters to a few centimeters, and not, as with typical lift-and-slide doors, to space it from the frame and lift it by at least several millimeters or often even several centimeters.

[0011] It is provided that the sash is mounted so as to be displaceable along the projection axis (x) on a carriage and / or a guide unit supporting the sash, wherein the center plane of the roller arrangement of the carriage and the guide arrangement of the guide unit is fixed in relation to the projection axis (x). Due to the coupling of sash and frame via a carriage and / or a guide unit with a bearing element, the sash can be moved away from the frame or placed against it by simply moving the sash relative to the bearing element along the projection axis (x), whereby a movement of the sash relative to the bearing element and thus also relative to the frame between a projection position and a pressure position can occur.Within the scope of the invention, the extended position refers to the position of the sash relative to the frame, in which the sash profile and frame profile are spaced apart from one another in such a way that a displacement of the sash along the displacement axis (z) or displacement plane (yz) is possible. The compression position, on the other hand, refers to the position of the sash relative to the frame, in which the frame profile and sash profile come into contact with one another in such a way that a sealing of the sash against or relative to the frame is achieved. In the compression position, the sash can optionally be locked to the frame.

[0012] In order to apply sufficient contact pressure of the leaf against the frame in the pressing position for reliable and energy-efficient use of the sliding door assembly, the invention provides that the carriage and / or the guide unit have a pressure adjustment device with an adjusting element. Using the pressure adjustment device, the position of a bearing element of the carriage and / or a bearing element of the guide unit can be adjusted along the projection axis (x) and relative to a center plane of the roller arrangement of the carriage and / or the guide arrangement of the guide unit, which is stationary with respect to the projection axis (x).

[0013] Within the scope of the invention, the bearing element forms the element relative to which the sash is mounted so as to be displaceable along the projection axis (x) for moving the sash between a projection position and a compression position. It has been recognized that by additionally displacing the bearing element relative to a center plane of the roller arrangement of the carriage and / or the guide unit, which is fixed in relation to the projection axis (x), the contact pressure in the compression position can be varied. Thus, even after the sliding door arrangement has been installed, the contact pressure exerted by the sash on the frame in the compression position can be easily adjusted so that sufficient sealing is achieved. A sealing element can be arranged between the frame and sash to further improve the seal.

[0014] The term "sliding door assembly" is to be understood as also encompassing a "window assembly." Preferably, the drive mechanism of the sliding door assembly comprises at least one carriage supporting the sash and a guide unit guiding the sash, wherein these are arranged at different positions on the sash. Optionally, both the at least one carriage and the at least one guide unit have a pressure adjustment device. It has been recognized that, depending on the installation position of the frame or sash, the position of the bearing element and thus the contact pressure of the carriage and the guide unit can be set identically or can differ from one another, particularly if the frame and sash were not sufficiently adjusted during assembly.

[0015] A guide unit comprises at least one bearing element for coupling to the sash and, as a guide arrangement, a slider arrangement or a roller arrangement for guiding the sash on the frame. It is known that the slider arrangement or roller arrangement of the guide unit is guided in a guide rail in the frame, which, for example, has an undercut groove.

[0016] When configured as a slider assembly, the guide assembly can have a guide element extending along a central longitudinal axis oriented orthogonally to the extension axis (x). The guide element is particularly configured such that it can engage with the guide rail on the frame, for example, in a groove formed there, and can be guided by the same. The guide element can be made of a softer material than the guide rail, for example, plastic. This contributes to low-wear operation.

[0017] When configured as a roller assembly, the guide assembly can comprise a roller or guide roller whose rotational axis runs orthogonally to the extension axis (x). The roller or guide roller is configured in such a way that it can engage with the guide rail on the frame, for example, in a groove formed there, and be guided by it. This also contributes to low-wear operation.

[0018] The carriage has at least one bearing element for coupling to the sash and a roller assembly for displacing the sash, with the sash being arranged above the carriage and thus on the carriage. The roller assembly of the carriage preferably has two rollers arranged one behind the other along the displacement axis (z). The rotation axis of the rollers of the carriage thus extends along or parallel to the extension axis (x).

[0019] The guide arrangement of the guide unit and / or the roller arrangement of the carriage can comprise bearing elements for supporting a guide or roller, e.g. retaining plates or cheeks. The center plane of the roller arrangement of the carriage can run through the roller perpendicular to the projection axis (x) and thus also perpendicular to the rotation axis of the roller of the carriage. The center plane of the guide arrangement, e.g. designed as a roller arrangement, of the guide unit can also run through the roller perpendicular to the projection axis (x) but along the rotation axis of the roller of the guide unit. In other words, both the center plane of the roller arrangement of the guide unit and the center plane of the roller arrangement of the carriage are spanned along the displacement axis (z) and a vertical axis or lifting axis (y) perpendicular to the projection axis (x) and parallel to the plane of the sash.Preferably, the rollers of the roller assembly are ball-bearing mounted and therefore run smoothly and are almost maintenance-free.

[0020] In a preferred embodiment, the carriage and / or the guide unit can each have a support element that can be (stationarily) attached to the sash. The running gear, in particular the bearing element of the carriage and / or the guide unit, is coupled to the sash by means of the support element, and the support element is displaceable relative to the bearing element along the projection axis (x). This creates a simple and robust coupling between the sash and the running gear, which can compensate for manufacturing and assembly tolerances to a certain extent.In addition, a carriage and / or a guide unit comprising a support element and a bearing element can be used flexibly, since the support element can be arranged almost arbitrarily on the frame. For adjustment, in particular to enable movement of the sash along the projection axis (x), only the bearing element and support element need to be aligned with each other, without the generally relatively heavy sash having to be handled for adjustment. Optionally, the support element is plate-shaped and has a supporting surface on or at which the sash is mounted.

[0021] Advantageously, the running gear can have a guide rail attached to the frame, on which the carriage is guided. The guide rail is preferably arranged in a stationary manner, in particular fixed to the frame. Since the rollers of the carriage are constantly in contact with the guide rail, the stationary position of the roller arrangement of the carriage, in particular the center plane of the roller arrangement of the carriage, relative to the extension axis (x) can be defined by the guide rail. The door leaf can thus be moved at a defined distance from the frame via one or more carriages, safely guided by the guide rail along the displacement axis (z). Preferably, the guide rail is arranged on the frame below the door leaf in the direction of gravity or is formed integrally with a horizontal profile of the frame.

[0022] In a preferred embodiment, the adjusting element of the pressure adjustment device can be designed as an adjusting bolt with an external thread, wherein the external thread of the adjusting bolt engages with an internal thread of the bearing element. The adjusting bolt is preferably mounted in a stationary manner relative to the projection axis (x), and the longitudinal axis of the internal thread of the bearing element and the external thread of the adjusting bolt extend along the projection axis, such that rotation of the adjusting bolt causes the bearing element to move along the projection axis (x) relative to the adjusting bolt. Thus, by actuating the adjusting bolt, the bearing element can be moved along the projection axis (x) in the direction of the frame in a simple manner, and the contact pressure of the sash on the frame can be adjusted based on the position of the bearing element.

[0023] Specifically, in order to create a stable design, the roller arrangement and / or the guide arrangement can have two cheeks, wherein the adjusting element is preferably fixed in place between the two cheeks with respect to the extension axis (x). The two cheeks are preferably aligned with one another such that the center plane of the roller arrangement or guide arrangement extending along the displacement axis (z) coincides with the center plane of the two cheeks. The cheeks can be used not only to fix the adjusting element but also to form two stops to limit the movement of the bearing element along the extension axis (x). The roller arrangement of the carriage is preferably designed such that, in addition to the adjusting element, at least one roller, preferably two rollers, are rotatably fixed between the two cheeks, in particular one roller at each of the axial ends of the cheeks.

[0024] The adjusting element can expediently be fixed to the cheeks by riveting or by means of a riveted connection, whereby the front ends of the adjusting element are preferably designed as rivets that interact with each cheek. The riveting is carried out in such a way that the adjusting element (after riveting) can rotate relative to the two cheeks or relative to the roller assembly (rotation around the longitudinal axis of the adjusting element). Rivets enable a connection that is both economical and permanent, as well as process-reliable.

[0025] Advantageously, the support element and the bearing element can each have form-fitting surfaces that are effective along the displacement plane (yz) and secure the support element against displacement relative to the bearing element along the displacement plane (yz). In this way, it is possible to secure the support element and thus also the sash arranged on the support element against movements or displacements in undesired directions. Specifically, only a movement of the support element relative to the bearing element along the extension axis (x) is permitted to reach the extension position, and displacements of the support element relative to the bearing element in other directions are blocked to prevent incorrect operation and excessive wear.

[0026] The pressure adjustment device, in particular the adjusting element, can expediently have an engagement section, in particular a hexalobular socket, for an adjustment tool. This enables adjustment of the pressure adjustment device, in particular the adjusting element, with simple handling. To access the adjusting element, an opening in the wing and / or in the pressure adjustment device that is only slightly larger than the adjustment tool is required. The ingress of dirt and the resulting wear of the adjusting element can thus be minimized. If the engagement section is designed in the manner of a hexalobular socket, simple adjustment can be carried out using commercially available tools.

[0027] In a preferred embodiment, the bearing element can be moved along the opening axis by means of the pressure adjustment device by at least one millimeter, preferably by at least two millimeters, more preferably by three millimeters, even more preferably by four millimeters, and even more preferably by five millimeters. This provides a sufficient adjustment range so that the contact pressure between the sash and frame can be precisely adjusted and readjusted even after the sliding door assembly has been completed.

[0028] The sash can be moved relative to the frame along the opening axis (x) between the open position and the closed position by a maximum of 20 millimeters, preferably by a maximum of 8 millimeters. In other words, the sash only needs to be spaced from the frame by a maximum of 20 millimeters to be able to be moved along the sliding axis (z) into the open position. Thus, compared to known sliding door arrangements, particularly lift-and-slide doors, whose sashes often have to be spaced from the frame by several centimeters and raised for opening, a significantly smaller space requirement or installation area is required.

[0029] A sealing element can expediently be arranged on the frame and / or the sash, which, when in the pressure-applied position, rests against the sash and the frame. The sealing element can further reduce the penetration of contaminants, moisture, cold, or heat, thus ensuring reliable and energy-efficient use of the sliding door arrangement. The sealing element is preferably designed as a circumferential sealing plane. More preferably, the sliding door arrangement has two circumferential sealing elements, one of which is arranged on the frame and one of which is arranged on the sash. When the sash is closed, the two sealing elements between the frame and sash are pressurized, which leads to increased tightness.

[0030] Specifically, the carriage can be arranged on a lower horizontal profile of the sash with respect to the vertical axis (y) and / or the guide unit can be arranged on an upper horizontal profile of the sash with respect to the vertical axis (y). In other words, the carriage is arranged below the sash in the direction of gravity and / or the guide unit is arranged above the carriage in the direction of gravity, so that the sash is supported by the carriage and guided by the guide unit. Preferably, the sliding door arrangement has at least one carriage arranged on a lower horizontal profile of the sash and at least one guide unit arranged on an upper horizontal profile of the sash. This enables easy and quiet movement of the sash along the sliding plane (yz).

[0031] Advantageously, the drive can have at least one additional carriage with a height adjustment device for adjusting the height of the support element along the vertical axis (y). This allows the contact pressure of the frame against the window in the contact position to be easily adjusted using one carriage with a pressure adjustment device, and the height of the support element along the vertical axis (y) and thus of the sash relative to the frame to be adjusted using the additional carriage with a height adjustment device. The height adjustment can be carried out, for example, using a height adjustment device having an eccentric.

[0032] Specifically, the drive can comprise three carriages and three guide units, with one carriage and one guide unit each having a pressure adjustment device, and two carriages each having a height adjustment device. This enables particularly secure guidance and support of the sash.

[0033] Within the scope of one possible design (adjustment of contact pressure in the middle of the sash), the running gear can be designed with three carriages and three guide units as follows: On the gear side of the sash (front end of the sash when closing the sash), a carriage (below) with height adjustment device can be arranged and the guide unit (above) can be designed conventionally (without pressure adjustment device).

[0034] In the center of the wing (center of the wing along the displacement plane (yz)) a carriage (bottom) with a pressure adjustment device and / or a guide unit (top) with a pressure adjustment device can be arranged.

[0035] A carriage (bottom) with height adjustment device can be arranged on the center locking side of the sash (rear sash end when the sash is pushed closed) and the guide unit (top) can be designed conventionally (without pressure adjustment device).

[0036] With this design (adjusting the contact pressure in the center of the sash), the variable contact pressure is only adjusted in the center of the sash. On the gear side of the sash (the front end when the sash is closed), a contact pressure can be applied by the engagement of locking elements in the strike plates arranged on the frame. On the center locking side of the sash (the rear end when the sash is closed), a contact pressure can be applied by the center locking mechanism.

[0037] If sufficient contact pressure cannot be achieved with this design (adjusting the contact pressure in the center of the sash), an alternative design can be implemented by equipping all three carriages (bottom) with a pressure adjustment device. Optionally, the guide units (top) can also be equipped with a pressure adjustment device.

[0038] Advantageously, the sash can be transferred into a ventilation position in which the sash is positioned along a projection axis (x) relative to the frame between the projection position and the pressure position, wherein in the ventilation position the displacement of the sash along the displacement plane (yz) is blocked. In the ventilation position the sash is thus spaced from the frame by a relatively small distance between the projection position and the pressure position such that although an exchange of air can take place between the interior space separated from the outside environment by the sliding door arrangement and the outside environment, the sash is nevertheless secured against unwanted, in particular unauthorized, opening. This can ensure a constant supply of fresh air while the sash is securely locked.

[0039] The invention is explained in more detail below with reference to the figures, in which identical or functionally identical elements are provided with identical reference numerals, if necessary, but only once. They show: Fig. 1 shows an embodiment of a sliding door arrangement in a schematic, partially sectioned overall view; Fig. 2 shows a carriage of the sliding door arrangement from Fig. 1 in an exploded view; Fig. 3 the carriage of the sliding door assembly from Fig. 2 with the bearing element in a first position in a sectional view (low contact pressure); Fig. 4 the carriage of the sliding door arrangement from Fig. 2 with the bearing element in a second position in a sectional view (increased contact pressure); Fig. 5 a guide unit of the sliding door arrangement from Fig. 1 in an exploded view; Fig. 6 the guide unit of the sliding door arrangement from Fig. 5with the bearing element in a first position in a sectional view (low contact pressure); Fig. 7 the guide unit of the sliding door arrangement from Fig. 5 with the bearing element in a second position in a sectional view (increased contact pressure); Fig. 8 the sliding door arrangement from Fig. 1 in a partially sectioned side view; Fig. 9 a Fig. 8 section marked X in an enlarged view; and Fig. 10 a Fig. 8 section marked Y in an enlarged view.

[0040] Figure 1 shows a sliding door assembly, designated overall by reference numeral 10. The sliding door assembly 10 has a stationary frame 12 (fixed frame 12) and a leaf 14 that is horizontally displaceable relative to the frame 12 along the displacement axis (z).

[0041] The frame 12 has a lower frame profile 16, an upper frame profile 18, and two side frame profiles 20, 22. The sash 14 has a sash frame 24 that defines a sash field 34, e.g., a glazing unit. The sash frame 24 has a lower horizontal profile 26, an upper horizontal profile 28, and side vertical profiles 30, 32. Locking bolt devices 42 and striker plates 48 are arranged on the side frame profiles 20, 22.

[0042] A guide rail 36 is arranged on the lower frame profile 16. In addition to the guide rail 36, the running gear comprises three carriages 38, 40 that run on the guide rail 36, and three guide units 44, 46 on the upper horizontal profile 28. A carriage 38 has a pressure adjustment device 70 (see Fig.2 to 4) and the two further carriages 40 have a height adjustment device. The guide unit 44 has a pressure adjustment device 70. Since the wing 14 is coupled to one of the carriages 38, 40 via a bearing element 52 and a support element 56 of the carriages 38, 40, the wing 14 can be displaced relative to the frame 12 along the displacement plane (yz) by means of the carriages 38, 40.

[0043] A guide rail 50 is arranged on the upper frame profile 18 (cf. Fig.1 ). The guide units 44, 46 are slidably guided in the guide rail 50. The sash 14 is coupled to each of the guide units 44, 46 via a bearing element 54 and a support element 58 of the guide unit 44, 46 and is thus guided at the upper end of the sash 14 (cf. Fig.5 to 7 ).

[0044] The wing 14 is between a, in Fig. 8 to 10shown, pressure position and an extended position along an extension axis designated "x". The extension axis x is orthogonal to the horizontal displacement axis z and thus extends according to the Fig. 1 shown representation out of the image plane.

[0045] The movement of the wing 14 between a pressure position and an extension position along the extension axis x can be effected by a motor or by means of a handle such as a handle 60, wherein the handle 60 can be moved from its Figure 1shown downwardly projecting position (pressure position) into a 180° rotated, upwardly projecting position (extended position) (opposite orientation of handle 60 in the extended position and pressure position is also conceivable). The movement of handle 60 is transmitted via transmission elements known per se and therefore not shown to the mutually movable bearing elements 52, 54 and support elements 56, 58, which serve to guide the spacing of frame 12 from sash 14.

[0046] Due to the form-fitting surfaces 72, 74 of the bearing elements 52, 54 and the support elements 56, 58 (cf. Fig.2 to 7), the sash 14 arranged on the supporting surface 90 of the supporting element 56, 58 can be guided and displaced relative to the bearing element 52, 54 and thus also displaced relative to the frame 12 along the deployment axis x. The displacement of the supporting element 56, 58 relative to the bearing element 52, 54 thus serves to transfer the sash 14 from the pressure-applied position to the deployed position or from the deployed position to the pressure-applied position.

[0047] In particular from the Figures 2 and 5 It can be seen that the vertically oriented form-fitting surfaces 72 and the horizontally oriented form-fitting surfaces 74 interact in such a way that only a displacement of the support element 56, 58 relative to the bearing element 52, 54 along the extension axis x is permitted.

[0048] In order to be able to adjust the contact pressure of the sash 14 in the contact position in addition to transferring the sash 14 between the pressure position and the extension position, a pressure adjustment device 70 is provided which enables a displacement of the bearing element 52, 54 along the extension axis x relative to a part of the carriage 40 or the guide unit 46 which is stationary with respect to the extension axis x.

[0049] For this purpose, the carriages 38, 40 (cf. Fig.2 to 4) has a part which is stationary with respect to the extension axis x. This stationary part comprises on the carriages 38, 40 at least the roller arrangement 62 with at least one roller 64 and the cheeks 68 for supporting the rollers 64. The rollers 64 of the carriages 38, 40 remain in constant contact with the guide rail 36 in the direction of the extension axis x and in the direction of the vertical axis y. Thus, the center plane M of the roller arrangement 62 of the carriage is stationary in the direction of the extension axis x (cf. Fig.3 and 4 ).

[0050] The command units 44, 46 (cf. Fig. 5 to 7 ) have a part that is stationary relative to the extension axis x. The guide units 44, 46 each have a guide arrangement 63, which in the example is designed as a roller arrangement 65 with a roller or guide roller 66. As explained above, the guide arrangement 63 can also be designed as a slider arrangement (not shown).

[0051] The guide roller 66 of the guide unit 44, 46 (cf. Fig.5 to 7 ) is fixed within a frame profile 18 with respect to the projection axis x, which is why the center plane M of the roller arrangement 65 of the guide unit 44, 46 is also fixed in the direction of the projection axis x. In contrast to the carriage 38, 40, the guide roller 66 of the guide unit 44, 46 is mounted in the frame profile 18 in such a way that the rotation axis 84 of the guide roller 66 coincides with the center plane of the roller arrangement 65. The rotation axes 84 of the rollers 64 of the carriage 38, 40, however, are perpendicular to the center plane M of the roller arrangement 62 of the carriage 38, 40. The center plane M is defined by the cheeks 68 and therefore runs centrally between the two cheeks 68.

[0052] The pressure adjustment device 70 of the carriage 38 and the guide unit 42 each has an adjusting element 76 for adjusting the contact pressure, which is fixedly and rotatably received between the cheeks 68. The section of the adjusting element 76 arranged between the cheeks 68 has an external thread 86 that interacts with a corresponding internal thread 88 of the bearing element 52, 54. By rotating the adjusting element 76, the bearing element 52, 54 can thus be moved between the cheeks 68 along the extension axis x.

[0053] The pressure adjustment device 70 is advantageously arranged on the carriage 38, which is arranged centrally between the two further carriages 40 with respect to the displacement axis z (compare Fig. 1 ). A further pressure adjustment device 70 is arranged on the guide unit 44, which is arranged centrally between the two further guide units 46 with respect to the displacement axis z.

[0054] With reference to the Figures 3 and 4 is an adjustment of the bearing element 52 of the carriage 38 relative to the center plane M in the negative x-direction along the extension axis x by 1.5 mm (cf. Figure 3 ) and in the positive x-direction along the extension axis x by 1.5 mm (cf. Figure 4 ) is possible. The pressure adjustment device 70 thus creates a sufficient adjustment range of 3 mm (millimeters) for adjusting the contact pressure. Figure 3 the bearing element 52 comes into contact with the left cheek 68, which in this case is the cheek 68 remote from the frame 12, whereby the bearing element 52 is as far away as possible from the frame 12. In Figure 4The bearing element 52 comes into contact with the right cheek 68, which in this case is the cheek 68 closest to the frame 12, whereby the bearing element is positioned as closest as possible to the frame 12. The cheeks 68, between which the pressure adjustment device 70 is received, each form a stop for the bearing element 52 and thus define the adjustment range of the pressure adjustment device 70.

[0055] With reference to the Figures 6 and 7 is an adjustment of the bearing element 54 of the guide unit 44 analogous to the adjustment of the bearing element 52 of the carriage 38 relative to the center plane M in the negative x-direction by 1.5 mm (cf. Figure 6 ) and in the positive X-direction by 1.5 mm (cf. Figure 7) along the extension axis x. Again analogous to the adjustment of the bearing element 52 of the carriage 38, the two cheeks 68 of the roller arrangement 65 of the guide unit 44 each form a stop for the bearing element 54 and thus define the adjustment range, which in this case is a total of 3 mm, of the pressure adjustment device 70. In Figure 6 the bearing element 54 is located as far away as possible from the frame 12 relative to the center plane M of the roller arrangement 65 and, in contrast, Figure 7 moved as close as possible to the frame 12 by means of the pressure adjustment device 70.

[0056] With reference to the Fig. 9 and 10The adjusting element 76 has an engagement section 78 for an adjustment tool 80. In the example, the engagement section 78 is designed as a hexagon socket. By actuating the adjusting element 76 using the adjustment tool 80, the bearing element 52, 54 can be moved relative to the roller arrangement 62, in particular relative to the center plane M of the roller arrangement 62, toward the frame 12 or away from the frame 12 along the extension axis x between the cheeks 68. This allows the contact pressure applied by the sash 14 to the frame 12 in the contact position to be adjusted.

[0057] In order to achieve an improved seal between the sash 14 and the frame 12, a circumferential sealing element 82 is arranged on the frame 12, which in the Fig. 9 and 10 shown pressure position on both the frame 12 and the wing 14.
