Guide system for a sliding wall arrangement at a building opening

Abstract

The invention relates to a rail guide for supporting and slidably guiding a sliding wall assembly (100) in a guide trench (120) at a building opening (200). It comprises a guide profile (10) which is or will be arranged in the guide trench (120) in the intended mounting position and leaves a channel (11) bounded on three sides (12, 13, 14) and open on one side (15). The channel (11) has an opening width (W) that is smaller than the thickness (D) of the sliding wall assembly (100). At least one roller assembly (40) is arranged in the channel (11). The rail guide further comprises a support profile (60) which includes an upright web section (61) and a transverse flange section (62). The web section (61) can be inserted into the channel (11) and supported by means of the roller assembly (40). The belt section (62) runs outside the channel (11) in the intended mounting position and spans the open side (15) of the channel (11).It also forms a receiving structure (63) for the sliding wall assembly (100). The guide profile (10) and the support profile (60) are made of a fiber-reinforced synthetic composite material, in particular a fiber-reinforced plastic. The sliding wall assembly enables the formation of a floor covering in the room sections (211, 212) on both sides of the building opening, extending to the particularly narrow channel (11) or the narrow-section guide profile (10), and complies with the applicable requirements for thermal insulation and resistance to driving rain for full-surface glass sliding doors. The figure selected for publication with the summary is Figure 1.

Description

[0001] The invention lies in the field of rail guides for sliding wall arrangements, in particular for frameless full-surface glass sliding doors.

[0002] In practice, it is common to install sliding wall systems, particularly full-surface glass sliding doors, on a building opening using track guides. These glass sliding doors typically consist of an insulated glass unit comprising at least two panes of glass, spacers between them, and a perimeter seal. A full-surface glass sliding door has no frame or such a discreetly designed frame that almost the entire building opening is closed solely by the glass sliding door and is thus perceived as a full-surface glass sliding door. Consequently, the preferably transparent surface of the glass sliding door appears to be the only element that closes the building opening.Providing a rail guide suitable for supporting and guiding such a full-surface glass sliding door presents particular challenges with regard to statics, ease of assembly, thermal insulation and resistance to driving rain.

[0003] The familiar track systems typically include a support frame that is permanently installed on the building. This frame is preferably embedded in a wall recess surrounding the building opening, allowing it to be installed in such a way that it is barely visible when the door is closed. However, the support frame is clearly visible along at least one section of its length in the direction of travel next to the sliding wall / glass sliding door, which sometimes leads to visually unappealing results.

[0004] This support frame of the known constructions has, at least in the foot area, and preferably also in the head area, a base profile with at least one guide groove. In the guide groove of the base profile, a linear guide structure is arranged in the known rail guides, which partially or completely supports the weight of the full-surface glass sliding door and allows the glass sliding door to move within the plane of the building opening. Such a rail guide is known, for example, from EP 3 527 763 B1 and LU 502 438 B1.

[0005] In conventional sliding door systems, the guide groove of the base profile has an opening width—that is, a clear extent perpendicular to the direction of travel of the glass sliding door—that is larger, and sometimes significantly larger, than the thickness of the glass sliding door. During installation, an edge section of the sliding door is inserted into the guide groove, with a portion of the glass pane being immersed within it. Sealing material is typically applied to the inward-facing wall sections of the guide groove, creating a seal against an edge section of the sliding door's side surface. This means the sealant is often in direct contact with the glass. Typical guide groove opening widths range from 5 to 10 centimeters.When the glass sliding door is moved into the open position along the guide track, the guide track remains, in previously known track systems, as a clearly visible depression open towards the building opening between the two sections of the room located on either side of the opening, particularly between the interior and exterior. This visible depression has several disadvantages. Firstly, it presents a tripping hazard when passing through the opening, thus posing a certain safety risk.

[0006] Secondly, dirt can easily accumulate in the large opening. And finally, foreign materials such as precipitation, dirt, or cleaning agents that slide down one side of the glass sliding door due to gravity are inevitably transported into the open side of the wider guide groove and the seals located there, necessitating regular or permanent cleaning and / or drainage of the base profile.

[0007] WO 2010 / 024703 proposes installing a strip in the guide trench that covers most of the trench and extends to just below the top edge of the base profile. This strip includes openings for rollers on which the glass sliding door can glide. While this design reduces the depth of the remaining recess in the guide trench, thus offering some improvement regarding the tripping hazard, it is difficult, if not impossible, to meet the thermal insulation and driving rain resistance requirements stipulated in Europe, and particularly in Germany, with this track configuration.

[0008] The object of the present invention is to demonstrate an improved guide technology for sliding wall arrangements, in particular for frameless, full-surface glass sliding doors. The invention achieves this object through the features of the independent claims.

[0009] The guidance technique according to the present disclosure comprises several aspects, each of which can be used individually or in combination and contribute to solving the task.

[0010] For the sake of simplicity, this disclosure describes the use of a track guide in the floor area of ​​a building opening, which constitutes the main application. The track guide can alternatively or additionally be installed in a ceiling or wall area. In this case, terms referring to structures located on the "floor," such as "floor covering," "floor structure," "rough floor," etc., are analogous to terms for corresponding structures on the ceiling or another wall, in particular "ceiling covering," "wall structure," and "rough wall surface."

[0011] A first aspect of the present disclosure relates to a rail guide for supporting and slidably guiding a sliding wall assembly along a guide trench. The guide trench can, in particular, be bounded by a base profile and be located at a building opening. The building opening is, in particular, a lateral wall opening, especially in an exterior wall of the building. The sliding wall assembly can have a known thickness, and the guide trench can have a known opening width. The rail guide proposed in the disclosure can be intended for subsequent installation on existing guide trenches and, for example, can be installed as a replacement for a guide system known from the prior art. Optionally, and preferably, the floor covering in at least one of the room sections can also be replaced or supplemented during such a replacement.

[0012] The rail guide according to the present disclosure comprises a guide profile, at least one roller assembly, in particular a plurality of roller assemblies, and a support profile. The guide profile can be arranged or is arranged in the guide trench in the intended mounting position. It leaves a channel bounded on three sides and open on one side. This channel has a clear opening width at the open side that is smaller, in particular considerably smaller, than the thickness of the sliding wall assembly. The at least one roller assembly can be arranged or is arranged in the channel. Preferably, a plurality of roller assemblies can be arranged or are arranged along the channel.

[0013] The narrow design of the open side of the channel creates a significantly narrower depression in the transition area between the room sections at the building opening compared to the "trough" described above. The flooring can be laid right up to this depression, so that when the sliding wall is open, there is an almost seamless transition between the room sections, especially between the interior of the building and the exterior.

[0014] The support profile comprises, in cross-section, a web section that stands upright in the intended mounting position and a flange section running transversely to it. The web section can be inserted into the channel of the guide profile in the intended mounting position and supported by the roller assembly. The flange section of the support profile runs outside the channel in the intended mounting position, and in particular at a small distance above it. The flange section of the support profile spans the open side of the channel and forms a receiving structure for the sliding wall / glass sliding door, possibly using a narrow frame rail that encompasses the edge of the insulating glass unit.

[0015] The support profile provides a sufficiently wide bearing surface for the sliding wall, particularly the glass sliding door, suitable for statically supporting its weight. Simultaneously, the web section provides a very narrow body section, allowing for support within the channel via the at least one roller assembly. Since the belt section spans the channel, a seal can be created between the underside of the belt section and an upward-facing side of the guide profile, eliminating the need for contact with any side surface of the sliding wall / glass. This results in narrow gaps, promoting particularly effective thermal insulation.

[0016] The guide profile and the support profile are made of a fiber-reinforced synthetic composite material, specifically a fiber-reinforced plastic. This material prevents excessively high heat conduction through the guide and support profiles, effectively preventing condensation from forming on the surfaces. Furthermore, the material possesses sufficient strength to support even very large sliding walls, particularly the weight of a triple-glazed, full-surface glass sliding door.

[0017] The track guidance system according to the present disclosure offers several advantages. By arranging the guide profile in the guide groove, a separate and significantly narrower recess is created in which the weight of the sliding wall assembly, in particular a glass door, and furthermore, especially a glass sliding door, can be supported and guided. Since the guide profile is significantly narrower than the thickness of the sliding wall assembly, liquids and other foreign substances that slide down the lateral surface of the sliding wall are not necessarily introduced into the track guidance system itself. Rather, they can reach a surface area of ​​the adjacent floor covering, where they can be collected, for example, during cleaning or, in the case of rain, at least a substantial portion can be drained away towards a drain located in front of the building opening.This counteracts the risk of insufficient liquid drainage through the main channel and also reduces the ingress of dirt and foreign matter into the main channel. Nevertheless, it is advantageous if drainage can also occur via the guide ditch.

[0018] The sliding wall arrangement comprises at least one movable sliding wall, preferably several sliding walls. Two or more sliding walls can preferably be arranged collinearly or parallel to one another in order to jointly cover the building opening. The track guidance according to the present disclosure preferably provides exactly one guide profile with exactly one open side or with exactly one channel for exactly one sliding wall or a group of collinearly arranged or guided sliding walls. This enables a particularly narrow and visually discreet design of the track guidance. Furthermore, advantages in terms of sealing are achieved.

[0019] It is possible to lay a floor covering directly adjacent to, or very close to, the outer surface of the guide profile, so that the floor covering can extend into a vertical overlap area of ​​the sliding wall assembly. Particularly on the outside of the track guide, the floor covering can optionally be laid with a slight outward slope, so that any liquids that fall on it tend to drain away to the outside.

[0020] Furthermore, the combination of guide profile and support profile creates particularly favorable thermal insulation. Compared to the usual manufacturing materials for rail guides, especially aluminum or steel profiles, the fiber-reinforced composite material offers a significantly higher thermal resistance.

[0021] Furthermore, by inserting the web section of the support profile into the upwardly (or towards the building opening) open channel of the guide profile, a wall arrangement with multiple overlapping cross-sections and narrow gaps in between is formed, resulting in particularly low thermal bridges.

[0022] In particular, it makes it possible to form a narrow gap between a lower edge of the sliding wall arrangement, especially a lower edge of the belt section on the support profile, and an upper edge of the guide profile and possibly a surface of the floor covering adjacent to the guide profile, which can be insulated by suitable sealing agents above the walkable area.

[0023] The channel in the guide profile, which is very narrow compared to the thickness of the sliding wall assembly, forms a particularly narrow and discreet interruption between the floor covering on one side and the floor covering on the other side of the building opening, unlike previously known rail guides. This is both visually appealing and advantageous in terms of preventing tripping hazards and the ingress of dirt.

[0024] The rail guidance system according to the present disclosure can advantageously be retrofitted into existing building openings or existing guide trenches. Alternatively or additionally, it can be used in new buildings.

[0025] According to an advantageous embodiment, the rail guide comprises at least one adapter assembly that can be inserted into the guide trench. In its intended mounting position, the adapter assembly can form a boundary within the guide trench, leaving a defined passage open. This passage is dimensioned such that the guide profile can be inserted into the passage and supported on three sides in cross-section. Alternatively or additionally, in its intended mounting position, the adapter assembly can cover at least one section of the open side of the guide trench and, at the point of overlap, form a bearing surface for the edge of the floor covering, particularly for the section of the floor covering that extends to the guide profile.

[0026] The adapter arrangement can be concealed under / behind the floor covering in the intended mounting position. The adapter arrangement allows the guide profile, as described in this disclosure, to be easily adapted to any size and shape of existing guide trenches. The adapter arrangement preferably comprises one or more adapter pieces, which are in particular designed as extruded profiles with a suitable cross-section. Relatively inexpensive and easily machinable materials such as aluminum or plastic are suitable for this purpose. Alternatively or additionally, the adapter arrangement can have one or more adapter pieces formed by a profile strip, which is made, for example, of an extruded synthetic material, in particular an extruded plastic, and furthermore, in particular, of a plastic that is at least partially foamed.Alternatively, one or more adapter pieces can also be partially or completely made of a fiber-reinforced synthetic material.

[0027] The adapter arrangement can also allow for adjustment of the mounting position of the guide profile in the vertical direction relative to the floor surface or to the installation height of the floor covering.

[0028] The profiles made from a fiber-reinforced composite material, i.e. at least the guide profile and the support profile, can thus be formed in only one cross-sectional shape or in only a small number of cross-sectional variants, so that the comparatively expensive manufacturing technology of these profiles can be implemented economically advantageously by using identical parts in high quantities.

[0029] An assembly method according to the present disclosure is provided for mounting a rail guide for a sliding wall assembly on a guide trench, which is preferably formed on a base profile located at a building opening. The assembly method preferably comprises the following steps, which can be carried out in the specified or in another sequence. A rail guide according to the present disclosure is provided. The guide profile is inserted into the guide trench. This is preferably done after prior or simultaneous insertion of an adapter assembly into the guide trench. The adapter assembly is preferably adapted to the cross-sectional profile of the respective guide trench. It leaves a passage within the guide trench for inserting the guide profile. The support profile is inserted into the channel of the guide profile, the support profile being supported by means of the at least one roller assembly.

[0030] According to a preferred embodiment, at least one opening section of the open side of the guide trench is covered with a floor covering. An edge area of ​​the floor covering can, in particular, extend horizontally to the guide profile, preferably leaving a tolerance gap between the floor covering and the guide profile. The tolerance gap is preferably less than 10 millimeters, and particularly less than 5 millimeters.

[0031] The floor covering, in particular a surface of the floor covering, can preferably be flush with the top edge of the guide profile in its vertical extent, or preferably be laid below the top edge of the guide profile by a tolerance dimension. This tolerance dimension is preferably less than 5 millimeters, and particularly less than 2 millimeters.

[0032] The installation method described in this disclosure offers several advantages. Firstly, an existing guide trench can be used to install a particularly attractive and modern full-surface glass sliding door on an existing building. The drainage system, which is typically already present in the guide trench, can continue to be used. Furthermore, the flooring can be laid in a visually appealing and safe manner, creating a new floor transition at the building opening. The track system is quick and easy to install, and some parts can be done without tools. Standard tools can be used for the subsequent installation of the flooring and the sliding wall / glass sliding door.

[0033] Further advantageous embodiments of the invention are specified in the dependent claims and the following detailed description.

[0034] The invention is illustrated in the drawings in an exemplary and schematic manner. These show: Fig. 1: a cross-sectional view of a rail guide according to the present disclosure; Fig. 2-4: isometric and partially broken-up representations of parts of the rail guidance according to Fig. 1; Fig. 5: a cross-sectional view through a floor section of a building opening in which two rail guides according to the present disclosure are provided in a parallel arrangement; Fig. 6-7: alternative cross-sectional shapes of a support profile; Fig. 8: a cross-sectional representation of an intermediate state as an optional step during the assembly process according to the present disclosure; Fig. 9, Fig. 10 and Fig. 12: Cross-sectional views for the arrangement of the guide profile and the support profile on differently shaped guide trenches, partly using different adapter arrangements; Fig. 11 and Fig. 13: Isolated representations of the guide profile and the respective adapter arrangement analogous to the representations in Fig. 10 and Fig. 12; Fig. 14: an isometric view of a building opening; Fig. 15: An enlarged principle cross-sectional view of the rail guidance according to the present disclosure.

[0035] Fig. Figure 1 illustrates, in its lower section, a standard profile 110, which forms an upward-opening guide trench 120. An adapter assembly 80, consisting of two adapter pieces 85 and 86 in the example shown, can be inserted into the profile. In the intended installation position, a passage 81 is left open between the adapter pieces. The passage 81 is bounded by at least one side surface 82 of the adapter assembly, in particular by a first adapter piece 85. An opposite boundary of the passage 81 can be formed by a wall of the guide trench 120 or by a second side surface 83 of the adapter assembly 80, in particular by a side surface 83 of a second adapter piece 86. A boundary located away from the building opening, in particular a lower boundary of the passage 81, can be formed by a base surface of the guide trench 120.Alternatively and preferably, the boundary of passage 81 located away from the building opening is formed by at least one bearing surface 84 of the adapter arrangement 80, in particular at least one bearing surface 84 on the first and / or the second adapter piece 85, 86.

[0036] Fig. Figure 3 shows an isometric view of the basic profile 110 with two adapter pieces 85, 86 inserted into the guide trench 120 according to the sectional view of Fig. 1. In Fig. Figure 15 shows a more abstract schematic representation of the arrangement.

[0037] The present disclosure illustrates a rail guide predominantly in a mounting position at the floor-side transition between a first space section 211 and a second space section 212, wherein these space sections 211, 212 are located on one side and the other side of a building opening 200. The first space section 211 can, in particular, be an interior space of the building, and the second space section 212 an exterior space, in particular an exterior space outside the building. The rail guide 1 according to the present disclosure can be mounted on a floor-side guide trench. Alternatively or additionally, mounting on a ceiling-side guide trench is possible and intended, as exemplified in Fig. 14 is illustrated.

[0038] The guide trench 120 can be present once or multiple times. In particular, two, three, or more guide trenches can be located adjacent to each other at the building opening 200. Corresponding cross-sectional views of a multiple arrangement of guide trenches are shown in the Fig. 5, Fig. 9, Fig. 10 and Fig. Figure 12 shows that one or more of the guide trenches 120 can be formed on a common base profile 110, which is preferably inserted into a recess 204 of a floor body 203 (or ceiling body) of the building. Alternatively, two or more base profiles 110 can be arranged adjacent to each other and, in particular, directly adjoining each other. Fig. 9, Fig. 10 and Fig. Figures 12 show different shapes and sizes of commonly used basic profiles 110, 111, 112. Different adapter arrangements 80, 80', 80" are provided for each of these profiles to achieve a substantially similar mounting position for the guide profile 10.

[0039] The following describes some preferred dimensions and size ratios, which are particularly common in the Fig. 5, Fig. 9 and Fig. 14 are illustrated.

[0040] The guide trench 120 has an opening width O, which can be equal to or greater than the thickness D of a sliding wall arrangement 100 to be installed, in particular equal to or greater than the thickness D of a glass sliding door 100 to be installed.

[0041] The guide profile 10 according to the present disclosure forms a channel 11 which, in the intended mounting position, is open to one side, and, in the case of a bottom-side arrangement, to the top. The open side 15, or opening, of the channel 11 has a clear opening width W that is (significantly) smaller than the thickness D of the sliding wall arrangement 100. The cross-sectional width FB of the guide profile 10 is also preferably (significantly) smaller than the thickness D of the sliding wall arrangement 100. Furthermore, the cross-sectional width FB of the guide profile 10 in the direction of extension of the open side 15 of the channel 11 is also (significantly) smaller in cross-section than the opening width O of the guide trench.

[0042] The thickness D of a sliding wall assembly 100, in particular a glass sliding door, is generally more than 40 mm, and in particular more than 50 mm. The opening width O of a guide groove commonly used in practice is often more than 50 mm, and in particular more than 60 mm.

[0043] The guide profile 10 according to the present disclosure can preferably have a cross-sectional width FB of less than 40 mm, in particular less than 30 mm. Thus, the guide profile is preferably significantly narrower than the thickness D of the sliding wall arrangement 100.

[0044] According to a preferred embodiment, the clear opening width W of the channel 11 can be less than one-third of the thickness D of the sliding wall 100. According to a preferred embodiment, the opening width W can be less than 20 mm, and in particular less than 15 mm.

[0045] Fig. Figure 15 illustrates a preferred mounting position in a schematic representation. Here, an adapter assembly 80 is inserted into the guide trench 120, comprising a first adapter piece 85 and a second adapter piece 86. The adapter assembly 80 forms a horizontal boundary within the guide trench 120 and leaves a defined passage 81 within the guide trench 120, which is dimensioned such that the guide profile 10 can be inserted into the passage 81.

[0046] In the intended mounting position, the guide profile 10 is aligned along the guide trench 120 and at least partially embedded in the cavity of the guide trench 120.

[0047] The guide profile 10 can have a cross-sectional height FH oriented transversely to the open side 15 of the channel 11, which is preferably greater than the depth FT of the guide trench 120 and preferably also greater than the depth PT of the passage 81 left open within the adapter arrangement 80. (cf. Fig. 9).

[0048] In other words, it is preferably provided that the guide profile 10, in the intended mounting position, projects beyond the guide trench 120, in particular by the amount of the intended installation height of the floor covering 210 (surface covering) above the raw floor 213 (the raw wall surface). In other words, the adapter arrangement is preferably adapted such that the depth PT of the unobstructed passage 81 is equal to the difference between the cross-sectional height FH of the guide profile 10 and the intended installation height of the floor covering 210, possibly including a desired tolerance dimension.

[0049] Within the guide profile 10, the channel 11 preferably has a substantially rectangular inner contour in cross-section. This rectangular inner contour is particularly upright in the intended assembly state.

[0050] Preferably at least one roller apparatus 40 can be arranged or is arranged in the channel 11. Fig. 1, Fig. 3 and Fig. Figure 4 illustrates a preferred embodiment. A roller assembly 40 can, for example, be inserted from an end face of the guide profile and fixed to the guide profile 10 by a suitable fastening means. The roller assembly 40 can have any configuration. In the example shown, the roller assembly 40 has a bolt or axle body 40 on a frame, on which a roller 41 is mounted, preferably via a suitable rolling bearing. The roller assembly 40 can also optionally include one or more thrust washers 41 or any other vertical bearing means.

[0051] The guide profile 10 and the support profile 60 consist of a fiber-reinforced synthetic composite material, in particular a fiber-reinforced plastic, and more specifically a glass fiber-reinforced plastic (GFRP). This gives the guide profile, on the one hand, very good thermal insulation properties and, on the other hand, sufficient mechanical strength to support the at least one roller assembly 40. One or more internal cavities 20, 69 can be provided within the wall of the guide profile 10 and / or the support profile 60. Such internal cavities 20, 69 can have a positive effect on stiffness. They can also result in material savings, which promotes the economical and resource-efficient use of the fiber-reinforced synthetic composite material.

[0052] In the example of the Fig. Figures 1 to 5 show a guide profile 10, which is joined from two profile halves. In a section of the guide profile 10 located away from the building opening, an internal cavity 20 is formed in which a connecting piece 16 is inserted. Preferably, the profile halves of the guide profile 10 and the connecting piece 16 are firmly joined together. The connecting piece 16 may preferably have insulating and / or damping material properties. According to an alternative and also preferred embodiment, the guide profile 10 is formed in one piece.

[0053] The upright web section 61 of the support profile 60 is inserted into the channel 11 in the intended mounting position and can be supported or is supported by the at least one roller assembly. The flange section 62 of the support profile 60 runs outside and, in particular, (just) above the channel 11 in the intended mounting position. The flange section 62 preferably spans the open side 15 of the channel 11 and forms a receiving structure 63 for the sliding wall assembly 100.

[0054] As can be seen from the presentation in the Fig. 15 and Fig. As shown in section 4, a vertical gap 32 and a horizontal gap 36 are formed in cross-section between the support profile 60 and the guide profile 10, both towards the first space section 211 and towards the second space section 212. Alternatively, it can be provided that the material section 62 spans only half of the open side 15 of the channel, preferably on the side facing the outside 211, with a vertical gap 32 formed between the support profile 60 and the guide profile 10 only on that side.

[0055] The rail guide according to the present disclosure preferably comprises a sealing arrangement 30 with at least one sealing means 31, 35. Particularly preferably, a first sealing means 31 can cover a web gap 32 or a vertical gap which, in the intended mounting position, is located in cross-section between the guide profile 10 and the web section 61 of the support profile 60.

[0056] Alternatively or additionally, the sealing arrangement 30 comprises at least one second sealing element 35. The second sealing element 35, in particular, spans a flange gap 36 or covers a horizontal gap that, in the intended mounting position, exists in the cross-section between the guide profile 10 and the flange section 62 of the support profile 60. The first and the second sealing elements can each be present singly or multiple times.

[0057] Fig. 1, Fig. 5, Fig. 9, Fig. 10 and Fig. Figure 12 illustrates a preferred embodiment of the sealing arrangement 30.

[0058] In the example shown, the first sealant 31 and / or the second sealant 35 is designed as a brush and / or lip seal. Alternatively, any other design type is possible.

[0059] According to a preferred embodiment, a receiving section 68 for a sealing element 31, in particular for a vertical sealing element, is provided on the guide profile 10 on a side 12, 13 facing the flange section 62 of the support profile 60. This sealing element 31 is preferably in contact with an opposing contact surface 18' on the guide profile 10.

[0060] Alternatively, the arrangement can be reversed, so that the sealing agent 31 is arranged on the guide profile (not shown), while on a side 12, 13 facing the chord section 62 of the support profile 60 a contact surface 68' is provided for the sealing agent 31, in particular vertical sealing agent, arranged on the guide profile 10.

[0061] Furthermore, a receiving section 18 for a second sealing element 35, in particular a horizontal sealing element, is preferably provided on the guide profile, especially on an inner side facing the channel 11. The sealing element 35 preferably bridges the horizontal gap 32 and rests against a contact surface 18' on a side surface of the support profile 60, in particular on a side surface of the web section 61.

[0062] Alternatively or additionally, according to a preferred embodiment, a contact surface 18' is provided on the guide profile in the area of ​​the open side 15 of the channel 11 for a sealing agent 35 arranged on the support profile 60, in particular for a horizontal sealing agent.

[0063] In other words, the arrangement of a receiving section 18, 68 for the sealant and a corresponding contact surface 18', 68' for this sealant can be provided as in the preferred embodiment according to the illustration in the figures. Alternatively, the arrangement can be reversed for at least one of the sealants 31, 35.

[0064] The sliding wall arrangement 100 can have any configuration. It comprises at least one movable sliding wall which can be supported on a support profile 60. Preferably, two or more sliding walls can be provided. Fig. 5, Fig. 9, Fig. 10, Fig. 12 and Fig. Section 14 describes preferred embodiments. A sliding wall can, in particular, be a glass sliding door comprising a preferably full-surface insulating glass unit 101. The insulating glass unit 101 preferably comprises several panes 102, between which spacers 103 and a seal 104 are provided in the edge region.

[0065] A frame rail 64 can preferably be arranged or formed on the receiving structure 63 of the support profile 60. The frame rail 64 can be C-shaped in cross-section. It is preferably designed such that it (exclusively) encloses an outermost side edge of the insulating glass unit 101, wherein the overlap essentially covers an end face 105 of the insulating glass unit 101 and each edge strip on the side surface with essentially the width of the spacers and / or the seal 104, as shown by way of example in Fig. 5 and Fig. Figure 9 shows that the frame rail 64 may optionally have a cover 65 on one visible side. The frame rail 64 can be made of any material, e.g., an aluminum profile or a fiber-reinforced synthetic composite material.

[0066] The rail guide according to the present disclosure, in particular the guide profile 10, may preferably comprise a vertical support means 19, in particular a slide rail, which supports the guidance of the web section 61 of the support profile 60 within the channel 11. Particularly preferably, a receiving section for the vertical support means 19 may be provided on a wall 12, 13 of the guide profile 10 oriented towards the channel 11, wherein a corresponding contact surface for the vertical support means 19 is preferably provided on the web section 61 of the support profile 60. Alternatively, the arrangement may be reversed, i.e., a contact surface for a vertical support means 19 arranged on the support profile 60 is provided on the guide profile 10. The receiving section for the vertical support means may be arranged as shown in the illustration in Fig. 1 to 5 are formed by the receiving section 18 for the sealant 35.
