Description

TECHNICAL FIELD

The present invention relates to a sliding wall arrangement with at least one wing, which is slidably mounted in a guide channel of a running rail that can be retracted into a building floor.

STATE OF THE ART

Sliding wall arrangements with at least one wing, which is mounted in a running rail that can be retracted into the building floor and can be moved along it, are well known. They allow a wide view and can be manufactured without thresholds and with a comparatively small frame portion. Because the lower running rail is sunk into the ground, a profile-free transition from the sash to the ground is possible. This allows for maximum light opening. The wings are usually multi-glazed and usually have a circumferential profile.

Good heat insulation and sound insulation are essential for such sliding walls. The running rails of such sliding walls therefore generally consist of at least two profiles, for example aluminum profiles, which are firmly connected to one another via heat-insulating connecting elements. The separation by such connecting elements, which are usually made of plastic, enables an effective thermal separation of the two profiles, in each of which a wing is slidably guided. Effective drainage is also essential for recessed running rails.

Such sliding walls are increasingly being created with thicker wings, which are intended to provide even better heat and sound insulation. Accordingly, the guide channels must be made wider so that these wider sliding walls can be installed can be sunk. However, such wide guide channels are rather undesirable, especially from an aesthetic point of view. In principle, it is also possible that such wide guide channels are unfavorable when using shoes with narrow heels. Depending on the country, there are also standards for disabled-accessible construction that limit the dimensions of thresholds and floor openings.

The prior art therefore includes, for example, the JP 2001311362 and the DE 28 44 877 Guide channels have become known which have a flap which is folded down when the door is open and which cover the upper opening of the corresponding guide channel. In order to be able to close the door again, this flap must be pivoted again, which can of course be complex and undesirable.

The JP2005133298 shows a sliding wall in which the guide channel is covered by steel strips which are attached to both sides of the sliding wall. When the door is opened, the steel band lying in the opening direction is bent back downwards by 180° at the outer end of the guide channel and returned to a part of the guide rail arranged below the guide channel. Other such solutions are in the US 2015/0033633 A1 and in the WO 2015/150991 A1 disclosed.

The WO 2012/156468 A1 shows a sliding wall arrangement in which a cover strip attached to the sliding wing slides over the guide channel when it is released when the wing is moved. When the sash is closed, the cover strip extends into a channel arranged outside the side door frame.

The options for such systems with retightened cover tape are limited. For example, such a solution cannot be used in sliding wall arrangements in which more than one displaceable wing is provided per guide channel. In sliding wall arrangements in which the guide channel is particularly long in relation to the movable wing, it can be difficult to provide enough storage space for the cover strip. In addition, the long masking tape can be moved and redirected Especially when dirt particles penetrate, the smooth movement of the sliding wing is impaired due to frictional forces.

The GB 13,915 A discloses a self-closing track for folding doors movable on rollers, in which the track is formed directly in a floor, which is partially covered at the top laterally by two profiles, so that a gap remains between the profiles. In the gap, a rod is resiliently mounted on spaced supports in the track as a guideway for the rollers on the folding doors.

The GB 457,874 describes a sliding wall in which a guide rail is embedded in a floor, which is covered by a flexible membrane, which lowers when a sliding door is moved on it and which rises again when the sliding door has been pushed further.

PRESENTATION OF THE INVENTION

The invention is based on the object of creating a sliding wall arrangement of the type mentioned, which avoids the disadvantages mentioned. The sliding wall should therefore also be able to be implemented with very wide guide channels, for example with a width of 50 mm and more, without causing aesthetic or other problems.

To solve this problem, a sliding wall arrangement is proposed, as specified in claim 1. Advantageous embodiments of the invention are specified in the dependent claims.

• zumindest einen Flügel mit einem unteren Rand,
• eine Laufschiene, welche in einem Gebäudeboden versenkbar ist und wenigstens einen Führungskanal aufweist, in dem der zumindest eine Flügel am unteren Rand verschiebbar gelagert ist, sowie
• zumindest ein Abdeckelement, welches zum Abdecken des wenigstens einen Führungskanals dient, wenn der Führungskanal von dem zumindest einen verschiebbaren Flügel freigegeben wird.

The present invention therefore provides a sliding wall arrangement comprising

• at least one wing with a lower edge,
• a running rail which can be retracted into a building floor and has at least one guide channel in which the at least one wing is slidably mounted at the lower edge, and
• at least one cover element, which is used to cover the at least one Guide channel is used when the guide channel is released by the at least one displaceable wing.

The at least one cover element has a raised state, in which the cover element covers the guide channel released by the wing, and a lowered state, in which the at least one cover element is lowered into the at least one guide channel, so that the at least one wing over the at least a cover element can be moved away.

The at least one wing has on its underside the at least one running surface, which is moved over the rollers when the wing is moved, so that they roll on the running surface or the rollers are attached to the underside of the at least one wing, so that it rolls on the one or more tread(s) provided in the guide channel when the sash is moved.

The at least one cover element can thus be lowered into the guide channel in order to enable the wing or wings to be moved over the cover element. To support the cover element in the lowered state, the guide channel, in which the at least one displaceable wing is mounted, is used.

The raised or lowered state usually refers to the entire cover element, which is raised or lowered along its entire longitudinal extent and as a whole, that is, moved up or down. The raising and lowering movement therefore in particular has a component that is perpendicular to the longitudinal direction of the cover element. It is possible for the lowering element to be moved a certain distance along its longitudinal direction. However, the travel of the lowering element along its longitudinal direction is preferably at most five times as large as the movement of the lowering element perpendicular to its longitudinal direction, more preferably at most twice as large as the movement perpendicular to the longitudinal direction and most preferably approximately in the order of magnitude of the movement perpendicular to the longitudinal direction. The longitudinal direction or the direction of the longitudinal extent of the cover element usually corresponds to the longitudinal direction or direction of the longitudinal extent of the running rail.

In comparison to the raised state, the position of the cover element in the lowered state preferably differs only by a parallel displacement. Preferably, the entire movement sequence of the cover element from the raised to the lowered state, and advantageously also the movement sequence from the lowered to the raised state, represents a pure parallel displacement.

Preferably, the cover element has the same overall shape in the raised state as in the lowered state, that is, it is neither bent, compressed, reduced in size, enlarged or otherwise reshaped. The cover element is advantageously designed in one piece as a whole.

The displaceable wing can be, for example, the wing of a sliding door or a sliding window, which is displaceable along the longitudinal extent of the running rail. The movable wing usually has at least one glass pane. The guide channel is advantageously covered by the wing in the area of the wing and by the at least one cover element in the areas outside the wing.

Preferably, the sliding wall arrangement has a closed position with respect to the at least one wing, in which the at least one wing closes a passage that can be closed by the sliding wall arrangement. In this closed position, the at least one guide channel is advantageously covered by at least one wing in the area of the at least one wing and by at least one cover element in all areas outside the at least one wing.

Lowering the cover element can be achieved in various ways. However, a spring mechanism is preferably arranged in the at least one guide channel, which applies a spring force directed towards the raised state to the at least one cover element. The lowering is then preferably effected with the aid of the weight of the wing acting on the cover element when it is displaced over the at least one cover element. The spring mechanism advantageously has one or more leg springs.

A guide means is provided, which is arranged in at least one guide channel and serves to support the at least one wing. The guide means can in particular be one or more rollers. The rollers are advantageously arranged in sequence and at regular intervals along the longitudinal extent of the guide channel. The at least one wing then generally has at least one running surface on its underside, which is moved over the rollers when the wing is moved, so that they roll on the running surface. Of course, in an alternative embodiment, the rollers can also be attached to the underside of the at least one wing, and one or more running surfaces can be provided in the at least one guide channel, on which the rollers can roll when the wing is moved. The running surface(s) arranged in the guide channel can also be viewed as a guide means in such an alternative embodiment.

In the raised state, the cover element is arranged above the guide means and advantageously covers it upwards. In the lowered state, the cover element is preferably projected upwards by the guide means. In the lowered state, the cover element is preferably lowered into the guide channel at least to such an extent that the top point of the guide means projects beyond it. The at least one wing can thereby be moved over the at least one cover element and at the same time be supported by the guide means.

The cover element advantageously has at least one recess in order to enable the guide means to protrude through the cover element in the lowered state. The recess can be designed to be open at the side or completely enclosed at the side by the material of the cover element. Providing at least one recess in the cover element enables greater coverage of the guide channel when the cover element is raised.

Preferably, a first and a second guide means are arranged in the guide channel, both of which serve to support the at least one wing and are advantageously spaced apart and extend parallel to one another along the direction of displacement of the wing. Both the first and the second means of guidance can be each act one or more rollers. Two parallel rows of rollers arranged one behind the other and running in the longitudinal direction of the running rail are advantageously provided, over which the at least one wing can be moved in such a way that the underside of the wing can roll over the rollers in turn. Even in such an embodiment, the rollers can of course also be attached to the underside of the wing, and one or more running surfaces for the rollers can be provided in the guide channel.

In a particularly preferred embodiment, the at least one cover element is connected to the running rail in such a way that the at least one cover element can be moved in a guided movement, in particular a parallel displacement, relative to the running rail from the raised to the lowered state and from the lowered to the raised state. In this way it can be ensured that the cover element is always arranged parallel to the running rail, which brings obvious aesthetic and functional advantages.

A guided parallel displacement of the cover element relative to the running rail can be achieved in a variety of ways, such as by means of a link guide. In a preferred embodiment, however, at least one support block is movably arranged in the at least one guide channel. This at least one support block is preferably movably connected to the running rail and the cover element in such a way that the guided movement, in particular parallel displacement, of the cover element is predetermined by the at least one support block. The at least one support block advantageously also serves to absorb weight forces which act on the at least one cover element in the raised state, and preferably also in the lowered state. In this way, significantly higher weight forces can be absorbed by the lowering element.

The at least one support block advantageously has a rounded rolling surface in order to enable the support block to roll evenly when the at least one cover element is brought from the lowered to the raised state or from the raised to the lowered state. In addition, the at least one support block preferably has a substantially flat standing surface.

By means of the flat base, the weight forces can be easily dissipated and undesirable further movement of the support block is prevented.

Preferably, the at least one cover element is designed as a profile rail with a substantially U-shaped cross section. Parts arranged in the guide channel can therefore be well protected from external influences and, in particular, penetrating dirt particles.

In order to move the at least one cover element when moving the wing in a substantially continuously uniform movement from the raised to the lowered state and from the lowered to the raised state, a wedge-shaped stop element is advantageously attached to the wing.

Optimal ease of movement of the at least one wing can be achieved if rollers are attached to its lower edge, which roll on an upper side of the at least one cover element when the wing is moved and thereby keep it in its lowered state.

Preferably, several cover elements are provided in order to advantageously completely cover a single guide channel in segments. The plurality of cover elements are preferably arranged one behind the other. In order to enable the best possible, continuous coverage and interlocking of cover elements arranged one behind the other, the cover elements, but at least one of the cover elements, can in certain embodiments have a first end with a part projecting along a first displacement direction of the wing and a second end with a Have a recess which extends along a second displacement direction of the wing that is opposite to the first displacement direction and is designed to be open to the outside. The recess is preferably designed to be complementary to the projecting part.

DESCRIPTION OF PREFERRED EMBODIMENTS

In the Figure 1 A sliding wall arrangement known in the prior art is shown. The Figures 2 to 13 show a first embodiment of a sliding wall arrangement according to the invention. In the Figures 14 and 15 Further embodiments of sliding wall arrangements according to the invention are shown. Similar or identically acting elements of the various embodiments of sliding wall arrangements are in the Figures 1 to 15 each provided with the same reference number.

The ones in the Figure 1 The sliding wall arrangement shown in the prior art has a running rail 1 with a first guide channel 11 and a second guide channel 12. The running rail 1 is formed by a profile rail whose cross section is identical over the entire longitudinal extent of the running rail 1. The two guide channels 11 and 12, which run parallel to one another, are delimited laterally towards the outside by a side web 13 and are separated from one another by a central web 14. The two side webs 13 and the central web 14 extend parallel to one another and perpendicularly upwards from a main section 15. The main section 15 thus connects the side webs 13 and the central web 14 to one another.

The running rail 1 is sunk into a building floor in such a way that the guide channels 11 and 12 are open at the top and the upper end faces of the side webs 13 and the central web 14 come to rest flush with the floor surface B.

The two guide channels 11 and 12 each serve to support one or more wings 2, which are guided and can be displaced along the longitudinal direction of the guide channels 11, 12. The wings 2 can in particular be wings of a sliding window or a sliding door. Due to the dimensions of the guide channels 11, 12 and because of the recessed arrangement of the running rail 1 in the building floor, a part of a frame 22 extending along the underside of the wing 2 can be completely accommodated by the respective guide channel 11 or 12. As a result, the lower part of the frame 22 is largely invisible to the viewer and the width of the light opening when looking through the glass panes 21 held in the frame 22 is maximized.

The lower part of the frame 22, which is arranged within the guide channel 11 or 12, has an upper channel 23 which is open towards the top and which serves to accommodate and hold the glass panes 21. Sealing elements 24 can be provided in the areas between the frame 22 and the glass panes 21.

The underside of the frame 22 forms two running surfaces 25 and 25' that extend parallel to one another, which in the present case are each curved. A lower channel 26 which is open towards the bottom can be provided between the two running surfaces 25 and 25'.

To guide the wings 2, a base rail 3 with attached rollers 4 and 4' is mounted in the guide channels 11 and 12. The base rails 3 are designed as profile rails with a cross section that is largely unchangeable along the longitudinal extent of the base rail 3. They each have a main section 31, from which two outer webs 32 and two inner webs 33 extend downwards in a vertical direction and parallel to one another. The outer webs 32 and the inner webs 33 each extend the same distance downwards and end with their lower end faces on the top of the main section 15 of the running rail 1.

The rollers 4 and 4' are at regular intervals along the longitudinal extent of the Running rail 1 is freely rotatable in two parallel rows between the outer webs 32 and the inner webs 33. The first row of rollers 4 forms a first guide means and the second row of rollers 4 'forms a second guide means for guiding the wing 2. The rollers 4 and 4' are each attached to roller axes 35 and 35', each of which extends from an outer web 32 extend to an inner web 33. An empty space remains between the inner webs 33 of the base rail 3 and is unused.

In the main section 31 of the base rail 3, recesses 34 are provided above the roller axes 35, 35 ', through which the rollers 4, 4' protrude in order to enable the running surfaces 25, 25' to rest on the rollers 4, 4'.

The radial outer surfaces of the rollers 4, 4' are designed to be complementary to the running surfaces 25 and 25' of the frame 22 due to their radially inward curvature. When moving the sash 2, the running surfaces 25 and 25' of the frame 22 rest on the rollers 4, 4', which roll on the running surfaces 25, 25' and thus ensure that the sash 2 can be easily moved. By interlocking the running surfaces 25, 25' and the running rollers 4, 4' with their complementary surfaces due to the respective curvature, lateral guidance of the wing 2, i.e. acting perpendicular to the direction of displacement, is achieved.

The base rails 3 can be firmly connected to the running rail 1, in particular welded to it. The running rail 1 can also be formed in one piece with the base rails 3.

The ones in the Figure 1 The prior art sliding wall arrangement shown has the significant disadvantage that the guide channels 11, 12 are exposed outside the displaceable wing 2. This means that dirt can easily penetrate into the guide channels 11, 12. In addition, the guide channels form a tripping hazard and are particularly unfavorable for high-heeled shoes.

At the in the Figures 2 to 13 In the embodiment according to the invention shown, these disadvantages of the prior art are solved in that a cover element 5 is provided, which has a raised state and a lowered state. In the In the raised state, the cover element 5 covers the guide channel 11 or 12, which would otherwise be exposed, as shown in FIG Figure 2 is shown on the left side at the guide channel 11. In order to enable the wing 2 to be moved over the cover element 5, this is brought into the lowered state, as shown in the Figure 2 is shown on the right side at the guide channel 12. The guide channel 12 is then covered by the wing 2.

The running rail 1 is identical to that of the prior art embodiment Figure 1 educated.

In contrast to that in the Figure 1 In the embodiment of the prior art shown, the base rail 3, which is essentially identical in design, is here arranged upside down in the running rail 1, so that the main section 31 rests directly on the main section 15 of the running rail 1 and the outer webs 32 and the inner webs 33 are separated from the main section 31 extend upwards. In contrast to the base rail Figure 1 indicates that of Figure 2 no recesses 34. The rollers 4, 4' are arranged here in such a way that they protrude upwards over the free ends of the inner webs 33 and outer webs 32 and thereby enable the running surfaces 25, 25' of the wing 2 to rest.

The cover element 5 is designed as a profile rail with a U-shaped cross section with a main section 51 and two outer webs 52 extending parallel to one another and downwards in a vertical direction. The top of the main section 51 comes essentially flush when the cover element 5 is in the raised state to lie with the floor surface B and largely covers the guide channel 11, 12 towards the top. The outer webs 52 rest with their mutually facing inner surfaces on the outer surfaces of the outer webs 32 of the base rail 3, whereby a laterally guided movement of the cover element 5 from the raised to the lowered state and vice versa is achieved. In addition, the parts arranged under the cover element 5 are better protected from the ingress of dirt particles due to the outer webs 52.

In the main section 51 of the cover element 5, recesses 54 are provided, which allow the rollers 4, 4' to protrude through in the lowered state of the cover element 5 make possible. The cover element 5 is thus arranged above the rollers 4, 4 'in the raised state and below the running surfaces 25, 25' of the frame 22 in the lowered state.

Between the two outer webs 52 of the cover element 5, two inner webs 53 each extend vertically downwards from the main section 51. However, the inner webs 53 extend less far downward than the outer webs 52. The inner webs 53 are connected to one another at regular intervals along the longitudinal extent of the cover element 5 by transverse axes 50 and 56, the functions of which will be explained later.

The top of the main section 51 of the cover element 5 has a slightly raised central part, which serves to roll off rollers 28, which are attached to the underside of the frame 22, when the wing 2 is moved. The rollers 28 are each freely rotatable in the lower channel 26 of the frame 22 via a transverse axis 27. The wing 2 is otherwise identical to that in the Figure 1 shown embodiment of the prior art.

The area of the base rail 3 between the two inner webs 33 is used in the present embodiment according to the invention to accommodate a spring mechanism with one or more leg springs 6. The spring mechanism applies a spring force to the cover element 5, which presses the cover element 5 towards its raised state. The one or more leg springs 6 each have two upper legs 61, the end regions of which, as shown in particular in a synopsis of Figures 2 and 5 is clearly visible, rest on the transverse axis 56 and are bent around it. Two lower legs 62 of the leg spring 6 each lie flat on the top of the main section 31 of the base rail 3. A helical part of the leg spring 6 is penetrated by a transverse axis 36, which is fastened with its respective ends to the inner webs 33 of the base rail 3.

Due to the spring force of the at least one leg spring 6, the cover element 5 is brought into its raised state and held in this state. If the wing 2 is pushed over the cover element 5, the cover element 5 is pressed into the lowered state against the spring force by the weight of the wing 2, which is transmitted via the rollers 28, and held in this state. By rolling the rollers 28 on the main section 51 of the cover element 5, the mutual friction between the wing 2 and the cover element 5 when moving the wing 2 is minimized.

In the area between the inner webs 33 of the base rail 3, support blocks 7 are also arranged, which are movably connected to the cover element 5 on the one hand and to the base rail 3 on the other hand. The connection to the cover element 5 takes place via a transverse axis 50, which projects through the support block 7 and around which the support block 7 can be freely rotated. The connection to the base rail 3 takes place via a transverse axis 37, which extends between the two inner webs 33 of the base rail 3, and around which the support block 7 is also freely rotatable. The support block 7 thus has two axle holes for the two transverse axes 50 and 37.

The support blocks 7, which are all identical, point in the side view, for example in the Figure 5 is shown, an elongated shape extending from the transverse axis 37 to the transverse axis 50. A first side of the support block 7, which faces in the longitudinal direction of the running rail 1 in the raised state of the cover element 5, is essentially flat and merges into a rounded surface in the areas of the axle holes, the one in the area of the transverse axis 50 being semicircular around the corresponding axle hole extends around. The one in the area of the transverse axis 37 extends over an angular range of approximately 75° around the corresponding axle hole and thereby forms a rolling surface 72 of the support block 7. This rolling surface 72 merges into a flat surface of a shoulder 71 attached to the support block 7. This flat surface forms a base 73 of the support block. In the side view, the shoulder 71 has a triangular shape, which is connected in one piece to a flat second side of the support block 7 along one of its side lines. The second side of the support block 7 is formed between the two rounded surfaces of the support block 7 and faces in the opposite direction compared to the first side.

From the Figure 5 It is clearly visible how the cover element 5 is supported in the raised state by two support blocks 7 and held in this position by a leg spring 6 arranged between them. The support blocks 7 stand with their standing surfaces 73 on the top of the main section 31 of the base rail 3. Due to the shoulder 71, the support blocks 7 are prevented from tipping over, which would otherwise occur due to the spring force of the leg spring 6 that may still be present in this position of the cover element 5 could.

When the wing 2 is moved, the cover element 5 is pressed horizontally along the longitudinal direction of the running rail 1 and downwards into the guide channel 11, 12 by means of a stop of the wing 2 at an end facing in the longitudinal direction of the running rail 1 against the spring force caused by the leg spring 6 ( Figures 5 and 6 ). The upper legs 61 approach the lower legs 62 of the leg spring 6. At the same time, the support blocks 7 tilt by approximately 90°, with the rolling surfaces 72 rolling on the main section 31 of the base rail 3. The cover element 5 can be lowered as far as possible until the shoulders 71 of the support blocks 7 abut the underside of the main section 51 of the cover element 5. The weight of the wing 2 holds the cover element 5 in the lowered state against the spring force. The cover element 5 is then located below the lower edge of the wing 2 and completely within the guide channel 11, 12 of the running rail 1 (see Figure 6 ).

Due to the support blocks 7, the cover element 5 moves from the lowered to the raised state and vice versa in a guided parallel displacement. It is therefore ensured in particular that the cover element 5 is always arranged parallel to the running rail 1 or to the floor surface B. Furthermore, the support blocks 7 enable a high load on the cover element 5 when the cover element 5 is in the raised state.

In order to achieve a lowering of the cover element 5 in a continuously uniform movement when the wing 2 is moved, a wedge 29 can be attached to the lower region of one or both of the end faces of the wing 2 facing in the direction of displacement (see, for example, Figures 8 and 9 ). At the end of the cover element 5, a freely rotatable roller 55 can also be attached, which moves on one when the wing 2 is moved lower inclined surface of the wedge 29 rolls. Due to the wedge 29, the force exerted by the wing 2 on the cover element 5 has both a horizontal and a vertical, downward force component.

If the wing 2 is only partially above the cover element 5, a certain opening in the running rail 1 remains outside the wing 2. The cover element 5 is in the lowered state, but the wing 2 is then not above the cover element 5 in all areas. However, even in the lowered state, the cover element 5 significantly reduces the exposed opening of the running rail 1 and then also covers the parts arranged in the running rail, such as in particular the leg springs 6, the support blocks 7 and the base rail 3, which has an aesthetically pleasing effect on the viewer . The cover element 5 thus still provides a certain amount of coverage for the guide channels 11, 12 even in the lowered state. By stopping the shoulders 71 of the support blocks 7 on the underside of the cover element 5, as shown, for example Figure 6 is shown, a high weight load on the cover element 5 is possible even in the lowered state.

Like it from the Figure 9 As can be seen, a plurality of cover elements 5 arranged one behind the other can be provided in a guide channel 11, 12, which are pressed downwards into the lowered state when the wing 2 is moved. The more cover elements 5 are provided, the shorter the areas between the wing 2 and the next cover element 5 that is in the raised state become. It is also easily possible for several displaceable wings 2 to be stored in a single guide channel 11, 12.

During the transition from the raised to the lowered state, the cover element 5 is moved over a certain distance along the longitudinal extent of the running rail 1 due to the tilting movement of the support blocks 7. In order to take this circumstance into account, particularly when there are several cover elements 5 arranged one behind the other, the outer webs 52 can each have a rounding 58 in the end regions of the cover elements 5, as shown in FIG Figures 10 and 12 is visible.

To provide continuous coverage and interlocking one behind the other To enable arranged cover elements 5, these each advantageously have a projecting middle part 59 in a first end region, to which the roller 55 is attached, and in a second, opposite end region a recess 57 which is open in the longitudinal direction of the cover element 5 and which is complementary to the projecting one Middle part 59 of the adjoining cover element 5 is formed. See the Figures 11 and 13 .

In the Figure 14 a second embodiment of a sliding wall arrangement according to the invention is shown. In contrast to that in the Figures 2 to 13 In the first embodiment shown here, the cover element 5 does not extend beyond the outer webs 32 of the base rail 3, but is located completely within the inner webs 33 of the base rail 3. Even in this embodiment, which is structurally somewhat simpler than the first embodiment, a certain amount of coverage is required Running rail 1 and reduction of the exposed guide channel 11, 12 achieved. The spring mechanism housed in the base rail 3 and the support blocks are also well covered by the cover element 5.

A third embodiment of a sliding wall arrangement according to the invention is in the Figure 15 shown. In this embodiment, several lamella-shaped and arranged cover elements 5 are provided, which are arranged upright in the guide channel 11 or 12. Between the cover elements 5, instead of just one thick one, several, specifically two, thin support blocks 7 are arranged parallel to one another, each of which is penetrated by a common transverse axis 50 and a common transverse axis 37. The transverse axes 50 also hold the cover elements 5 arranged parallel to one another together. Here too, the cover elements 5 cover the running rail 1 and reduce the size of the exposed guide channel 11, 12.
