Description

The present invention relates to a sliding wall assembly according to the preamble of claim 1.

Such sliding wall arrangements - also called sliding door or sliding window - can be produced without thresholds and with a comparatively small frame portion. The orientation is usually such that the sliding sash is moved horizontally. Due to the preferred sinking of the lower track in the floor, a profile-free transition of the sliding sash to the floor is possible. This results in maximum light opening. The sliding sashes are usually equipped with multi-pane heat-insulating glazing and usually have a circumferential profile.

Good thermal insulation and soundproofing are essential in such sliding wall assemblies. The running rails of such sliding wall arrangements are therefore usually made from 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 sliding leaf is slidably guided. In the case of sunken rails, effective drainage is also essential.

Increasingly, such sliding wall arrangements are being created with thicker sliding panels, which are intended to enable even better heat and sound insulation. Correspondingly, the guide channels must be made wider so that these wider sliding wall arrangements can be sunk into them. However, such wide guide channels are rather undesirable, particularly 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. There are also country-specific standards for disabled-accessible construction, which limit the dimensions of thresholds and floor openings.

From the prior art, for example, by the DE 20 2017 007 036 U1 a sliding wall arrangement with a movable cover element has become known. The cover element can be lowered into and raised from the guide rail by a parallelogram mechanism. Concealed when raised the cover element an opening of the guide rail, in the lowered state a sliding leaf of the sliding wall arrangement can slide over the cover element.

This sliding wall arrangement has proven itself very well in practice, but it also has disadvantages. One of these disadvantages is the relatively large distance between the cover element and the sliding leaf of the sliding wall arrangement when the cover element is in the raised state.

Furthermore, the parallelogram mechanism of the cover element only works from one side. i.e. in a sliding wall arrangement with three sliding leaves, one sliding leaf could only be moved in one direction, since the lowering element can only be lowered in one direction—due to the spring mechanism—so that there is a further need for optimization here.

Accordingly, the object of the present invention is to specify a sliding wall arrangement with a cover element which at least partially overcomes these disadvantages.

This object is achieved with a sliding wall arrangement which has at least one sliding leaf with a lower frame profile, a running rail which can be lowered into a building floor and in which the at least one sliding leaf is slidably mounted at the lower edge, and at least one cover element which is used to cover the at least one running rail serves when the running rail is released from the at least one displaceable sliding leaf, the at least one cover element being in a raised state, in which the covering element covers the running rail released by the sliding leaf in sections, and in a lowered state, in which the at least one covering element is in the at least a running rail is lowered into it, so that the at least one sliding leaf can be slid over the at least one cover element, a guide device being provided which ensures that the at least one cover element can be moved between the raised state nd and the lowered condition or vice versa performs a vertical or substantially vertical movement.

This creates a sliding wall arrangement with a cover element, in which the cover element can advantageously be lowered independently of the direction of displacement of a sliding leaf of the sliding wall arrangement. Furthermore, the lowering mechanism according to the invention advantageously requires only a small installation space parallel to the displacement direction of the sliding leaf, so that a movement of the cover element is kept to a minimum in the vertical or substantially vertical movement parallel to the sliding direction of the sliding sash.

It can further be provided according to one embodiment variant that the base rail has a link guide as the guide device, the cover element being guided by the link guide during its vertical or essentially vertical movement. This results in a robust guide of the cover element that is simple to implement in terms of design and production technology.

In a further variant of the invention it can be provided that the guide pin engages through a link-like guide groove which is introduced into a guide block. This results in a structurally simple and space-saving and therefore advantageous guidance of the movement of the cover element.

It is also advantageous if the guide groove is designed in the form of a U rotated through 180°, so that the movement of the guide pin in the guide groove is vertical, at least in sections. This further optimizes the structurally simple and space-saving guidance of the movement of the cover element.

In a further embodiment of the invention, it can be provided that the U-shaped guide groove has a recess at the apex or turning point of the U, into which the guide pin engages in its upper end position, so that the guide pin assumes a defined upper end position. This results in a structurally simple and therefore advantageous stable state of equilibrium of the guide pin and thus of the cover element in its upper end position.

Furthermore, in a further embodiment of the invention it can be provided that the guide bolt is held by one or more, in particular two, holding elements, with which the guide bolt is screwed and the holding elements are each fastened on the outside of the inner webs of the cover element. This results in a structurally simple and therefore advantageous good guidance of the guide pin.

According to a further embodiment variant of the invention, it can be provided that a guide rail is inserted into the base rail and the guide rail is connected to the base rail via insulating bars. As a result, the base rail has a simple design and is therefore advantageously isolated from the running rail.

A further variant of the invention provides that the insulating bars form a T-shaped cross-sectional geometry with which they engage in corresponding grooves in the guide rail. This results in an advantageously simple installation of the guide rail in the base rail.

In a further embodiment variant of the invention, it can be provided that the guide rail is designed symmetrically or essentially symmetrically and has two outer webs arranged symmetrically to one another and two inner webs also arranged symmetrically to one another. The symmetrical design results in a guide rail that is advantageously easy to manufacture.

According to a further embodiment variant of the invention, provision can be made for a rotatably mounted guide roller to be arranged between an outer web and an inner web, so that the guide rollers are arranged in pairs. This results in simple assembly and robust storage of the guide rollers.

According to one variant, it can also advantageously be provided that the cover element has a cross-sectional geometry in the form of a U rotated through 180°. This results in a cover element that is easy to manufacture and yet sufficiently stable in operation because it is sufficiently stiff.

A further variant of the invention provides that the clear width of the cover element is dimensioned such that the cover element, in its lowered state, engages over the two outer webs of the guide rail with its two legs. This advantageously results in a compact structure for the base rail.

In a further embodiment variant of the invention, it can be provided that the cover element has one or more, in particular two, inner webs, between which a bearing bolt is arranged, which is fastened to the inner webs. This results in a simple and robust attachment of the bearing pin.

In a further embodiment variant of the invention, provision can be made for the cover element to be penetrated by the guide rollers in the lowered state and for the cover element to have corresponding openings through which the guide rollers reach.

It can preferably also be provided that in the running rail at least one spring mechanism with at least one spring for raising and lowering the respective Covering element is provided. By the respective spring mechanism, the cover is easily by an energy storage z. B. a spring movable.

Provision can further preferably be made for two carriages to be arranged in pairs in the running rail and guided in a translatory manner, in particular between the inner webs, in pairs for each spring mechanism. This results in a structurally simple guidance of the spring of the spring mechanism.

In a further embodiment variant of the invention it can be provided that the spring mechanism has a spring which is designed as a leaf spring, in particular as an angled leaf spring, which is supported in an articulated manner centrally on the bearing bolt. The leaf spring is a structurally simple spring that can be produced with little effort in terms of production technology, which supports a vertical or essentially vertical movement of the cover element due to its geometry.

In a further variant of the invention, it can advantageously be provided that the spring is designed symmetrically and has a left and a right angled leg. The symmetry of the spring ensures in a simple and advantageous manner that the spring does not have a preferred direction of movement directed parallel to a direction of displacement of the sliding sash.

In a further variant of the invention it can be provided that the respective carriage has one or more, in particular four, rollers which are rotatably mounted. This advantageously results in a low-friction movement of the carriage and thus of the spring in a direction of movement parallel to the direction of displacement of the sliding sash.

It can advantageously be provided that in the running rail several of the cover elements are offset relative to one another in the main extension direction of the running rail and/or several of the spring mechanisms and/or several of the link guides are distributed.

Further advantageous embodiments of the invention can be found in the dependent claims.

The terms used below, such as "top", "bottom", "right", "left", "sideways", "vertical", "horizontal" refer to the respective drawing level.

11 shows a schematic representation of a sliding leaf 2 of a sliding wall arrangement with a cover element 5 according to the prior art.

The sliding sash 2 is guided in a base rail 3 . This has rollers 4 for this purpose. The base rail 3 can be inserted into a running rail 1 or formed integrally with it. The cover member 5 can be brought into a raised state and a lowered state. When raised, the cover element 5 covers a guide channel 11 or 12 above the base rail 3, but inside the running rail 1, which would otherwise be exposed. In order to enable the sliding leaf 2 to be moved over the cover element 5, this is brought into the lowered state. The guide channel 12 is then covered by the sliding panel 2.

A spring mechanism with one or more torsion springs 6 is arranged in the area of the base rail 3 . The spring mechanism applies a spring force to the cover element 5, which pushes the cover element 5 in the direction of its raised state. The one or more torsion springs 6 each have two upper legs 61, the end regions of which rest on a transverse axis 56 and are bent around it.

Because of the spring force of the at least one torsion spring 6, the cover element 5 is brought into its raised state and held there. When the sliding wing 2 is slid over the cover element 5, the covering element 5 is pressed against the spring force into the lowered state and held there by the weight of the sliding wing 2, which is transmitted by rollers 28. The rolling of the rollers 28 on a main section 51 of the cover element 5 minimizes the mutual friction between the sliding panel 2 and the cover element 5 when the sliding panel 2 is displaced.

Support blocks 7 are also arranged in the area of the base rail 3 and 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 in each case via a transverse axis 50 which protrudes through the support block 7 and about which the support block 7 can be rotated freely. The connection to the base rail 3 takes place in each case via a transverse axis 37 which extends in the base rail 3 and around which the support block 7 can likewise be rotated freely. The support block 7 thus has two axle holes for the two transverse axles 50 and 37 .

When the sliding leaf 2 is moved, the cover element 5 is pushed horizontally along the longitudinal direction of the running and base rails 1, 3 and downwards into the guide channel 11 by the sliding leaf 2 striking an end facing in the longitudinal direction of the running rail 1 against the spring force caused by the torsion spring 6 , 12 pressed. The upper legs 61 thereby 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 is lowered as far as possible until shoulders 71 of the support blocks 7 strike the underside of the main section 51 of the cover element 5 . The cover element 5 is held in the lowered state against the spring force by the weight of the sliding leaf 2 . The cover element 5 is then located below the lower edge of the sliding leaf 2 and completely within the guide channel 11, 12 of the running rail 1.

Due to the support blocks 7, the cover element 5 is moved from the lowered to the raised state and vice versa in a guided parallel displacement. It is thus ensured in particular that the cover element 5 is always arranged parallel to the running rail 1 or to a floor surface B. Furthermore, the support blocks 7 allow 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 sliding leaf 2 is displaced, a wedge 29 can be attached to the lower region of one or both of the end faces of the sliding leaf 2 facing in the direction of displacement. A freely rotatable roller 55 can also be attached to the end of the cover element 5, which rolls on a lower inclined surface of the wedge 29 when the sliding leaf 2 is displaced. Because of the wedge 29, the force exerted by the sliding leaf 2 on the cover element 5 has both a horizontal and a vertical force component directed downwards.

During the transition from the raised to the lowered state, the cover element 5 is moved over a specific distance along the longitudinal extent of the running rail 1 due to the tilting movement of the support blocks 7 . In order to take account of this fact, particularly in the case of a plurality of cover elements 5 arranged one behind the other, the outer webs 52 can each have a rounded portion 58 in the end regions of the cover elements 5 .

This results in the problem that a certain area of the running rail 1 cannot be covered by a cover element 5, since a covering element-free area must be reserved in the region of the running rail 1, into which a covering element 5 adjoining a wall reveal must move during its pivoting movement. when it is brought into the lowered state by the sliding sash. Alternatively, the rail 1 must extend further into the wall in the area of the wall reveal, which means more work.

Furthermore, the parallelogram mechanism of the cover element 5 only works from one side. i.e. in the case of a sliding wall arrangement with three sliding leaves, one sliding leaf could only be moved in one direction, since the lowering element can only be lowered in one direction, due to the spring mechanism.

The invention solves these problems in an advantageous manner, which is described below with reference to a preferred embodiment of the invention. The invention is not limited to this embodiment. In addition, the features disclosed below can also be combined differently within the meaning of the claims than shown below.

In Fig. 1a a running rail 300 with a cover element 500 is shown in a raised state. A single running rail 300 for a single movable sliding panel 200 of the sliding door is shown here. There can also be two or more running rails 300, which can then be combined in one piece to form a component. This is particularly the case when there is more than one movable sliding panel 200.

The running rail 300 can be built into a building floor sunk.

The at least one running rail 300 can have one or more hollow chambers 301 in the area of a base web. The running rail 300 has a substantially U-shaped cross-sectional geometry. A respective leg 302a, b of the running rail 300 has an upper groove 303a, b and a lower groove 304a, b at its free end. A seal 305a, b, which can be designed as a brush seal, is inserted into the upper grooves 303a, b. An elastic seal 306a, b is inserted in each of the lower grooves 304a, b. The running rail 300 can be made of a light metal, particularly preferably made of aluminum.

A base rail 307 is inserted into the running rail 300 . The base rail 307 is connected to the running rail 300 via insulating bars 308a, b. For this purpose, the insulating webs 308a, b form a T-shaped cross-sectional geometry here, with which they engage in corresponding grooves 309a, b in the base rail 307. The insulating webs 308a, b are made from a plastic material with good thermal insulation properties.

The base rail 307 is designed symmetrically or essentially symmetrically and accordingly has at least two, exactly two here, outer webs 310a, b arranged symmetrically to one another and at least two, here exactly two, likewise arranged symmetrically to one another, inner webs 311a, b. Between each outer web 310a, b and an inner web 311a, b, a guide roller 312a, b is rotatably mounted, so that the guide rollers 312a, b are arranged in pairs here. An axis 313a, b for mounting the respective guide roller 312a, b can be designed as a shoulder screw.

A spring mechanism 600 is arranged in multiple sections—here twice—in the running rail 300 . The spring mechanism 600 will be explained later in detail. For each spring mechanism 600, two carriages 601a, b are arranged in pairs in the running rail 300 and are guided in a translatory manner between the inner webs 311a, b of the base rail 307.

The cover element 500 has a cross-sectional geometry in the form of a U rotated through 180°. The clear width of the cover element 500 is dimensioned here such that the cover element 500, in its lowered state, engages over the two outer webs 310a, b of the base rail 307 with its two legs 501a, b, as shown in Figure 1b is shown. The cover element 500 also has at least one inner web 502, here two inner webs 502a, b, between which a bearing pin 503 is arranged, which is attached to the inner webs 502a, b. A spring 602 is movably mounted on the bearing pin 503 . The covering element 500 is provided for covering the running rail 300 when the running rail 300 is released from the at least one sliding leaf 200 of the sliding door.

In Fig. 1b the cover element 500 is shown in its lowered state, so that it can be driven over by a sliding panel 200 of the sliding door, of which a lower frame member 201 is shown here. In the lowered state, the cover element 500 is penetrated here by the guide rollers 312a, b. Accordingly, the cover element 500 has corresponding openings 504a, b (see Fig. 2d ) on. The lower frame member 201 has two guide shafts 202a, b on its underside, which each engage in a guide surface 314a, b of the respective guide roller 312a, b, as a result of which the sliding leaf 200 is guided in a displaceable manner. An interior of the running rail 300 is sealed off from the environment by the seals 305a, b and 306a, b, which cling to the frame beam 201 of the sliding leaf 200.

In Figure 2a is the spring mechanism 600 in an exploded view and in Figure 2b shown assembled in plan view. The spring 602 is designed here as an angled leaf spring, which is supported in an articulated manner on the bearing pin 503 by a half eyelet 603 arranged in the middle. The spring 602 is preferably designed symmetrically and accordingly has a left and a right angled leg 604a, b. At a free end of the respective leg 604a, b, the spring 602 has a device, here half an eyelet 605a, b, which encompasses a respective bolt 606a, b. The bolt 606a, b is inserted into the carriage 601a, b. The carriage 601a, b here has four rollers 607a, b, c, d, which are rotatably mounted on an axis 608a, b.

In Figures 2c and 2d the spring mechanism 600 is shown mounted in the track 300 . Here, the cover member 500 has been brought into a raised state by the spring mechanism 600 due to a force of the spring 602 acting vertically upward. The bearing pin 503 is aligned with the guide rollers 312a, b, and the openings 504a, b for the guide rollers 312a, b in the cover element 500 are clearly shown.

In Figures 3a to 3c such as Figures 4a to 4c the spring mechanism 600 is shown without adjacent components in the assembled state. This shows how the spring 602 moves from the raised state ( Figure 3a to 3c ) to the lowered state ( Figure 4a to 4c ) of the cover member 500 is elastically deformed. When the spring 602 is deformed by the lowering movement of the cover element 500, the two carriages 601a, b each move backwards due to the articulated coupling of the spring 602 via the respective eyelet 605a, b and the respective bolt 606a, b with the respective carriage 601a, b outside like this in Figures 4a to 4c is shown. This allows the bearing pin 503 to move vertically downwards. Movement up to the raised position is analogous. The carriages 601a, b are each moved inwards. The carriages 601a, b are displaceably guided via the rollers 607a to 607d in the running rail 300 between the two inner webs 311a, b of the base rail 307.

In this respect, the cover element 500 experiences a vertical or essentially a vertical movement between the raised state and the lowered state and vice versa by a guide device, which is explained in more detail below and which advantageously takes up less space in a direction parallel to the longitudinal extension of the running rail 300. as a pivoting movement.

In Figures 5a and 5b is shown that a guide device is provided so that the at least one cover element 500 performs a vertical or substantially vertical movement between the raised state and the lowered state or vice versa. The guide device has a link guide 700 here, or is designed here as a link guide.

In Figures 5a and 5b the running rail 300 with a guide pin 701 and a guide block 702 is shown in each case.

The guide pin 701 and the guide block 702 are functional elements of the slotted guide 700, with which the cover element 500 is guided on the way from its raised state to its lowered state and vice versa.

The guide pin 701 is held by at least one holding element 703, in this case two holding elements 703a, b, to which the guide pin 701 is screwed. The holding elements 703a, b are each attached to the outside of the inner webs 502a, b of the cover element 500. The holding elements 703a, b are preferably made of a metallic material.

The guide pin 701 passes through a link-like guide groove 704 (not shown here, see Figures 6a and 6b ), which is introduced into the guide block 702. The guide block 702 is fastened to the running rail 300 between the two inner webs 311a, b. The guide block 702 reaches through an opening 315 in the running rail 300 and can--as shown here--engage in the hollow chamber 301 of the running rail 300. The holding elements 703a, b can also reach through the opening 315 and engage in the hollow chamber 301 when the lowering element 500 is in the lowered state.

In Figures 6a and 6b is shown in each case the link guide 700 with the guide pin 701 in an upper end position. The respective holding element 703a, b here has a symmetrical, T-shaped geometry. The fastening points of the respective holding element 703a, b are arranged in an upper region of the T, in which the respective holding element 703a, b is attached here with screws to the cover element 500 (not shown here, see Figures 5a and 5b ) is attached.

The guide groove 704 is designed in the form of a U rotated by 180° and has a depression 705 at its apex or turning point, into which the guide pin 701 engages in its upper end position, so that the guide pin 701 assumes a defined upper end position in which the guide pin 701 is in a stable balance. Consequently, in its raised state, the covering element 500 can safely absorb forces that are acting on it—such as occur, for example, when a person steps on the covering element 500—without avoiding such a load.

Due to the U-shaped design of the guide groove 704, the cover element 500 experiences a vertical or essentially vertical movement between the raised state and the lowered state and vice versa, since this also occurs in the areas greater curvature in the "U" there is always a vertically downwards or upwards directed component of a movement vector of the guide bolt 701, which only becomes zero at the apex or turning point of the U -ie in the upper end position of the guide bolt 701. In other words, the movement of the guide pin 701 in the guide groove 704 is vertical, at least in sections.

Such a vertical movement or a movement that acts essentially as a vertical movement of the guide pin 701 and thus of the cover element 500 advantageously takes up less space in a direction parallel to the longitudinal extent of the base rail 300 than a pivoting movement.

The guide block 702 can also be designed symmetrically and can have at least one, in this case two, cutouts 706a, b on the side, which laterally guide the holding elements 703a, b when the holding elements 703a, b move downwards. The guide block 702 can have two or more—in this case exactly two—threaded holes, via which it is fastened to the base profile 300 with screws (see Figures 5a and 5b ).

In Figures 7a and 7b the link guide 700 with the guide pin 701 is shown in a lower right end position and in a lower left end position. This representation was only chosen for the sake of simplicity. In this respect, the guide bolt 701—and with it the cover element 500—can be located either in a lower left end position or in a lower right end position.

The distance between the two lower end positions of the guide pin 701 -and thus a longitudinal displacement of the cover element 500 when it moves out of the raised state- corresponds to the distance between the legs of the U-shaped guide groove 704. In this respect, this distance can advantageously be calculated according to purely geometric criteria and thus independently of the vertical distance of a surface OF of the covering element 500 between the lowered state and the raised state of the covering element 500, which must be taken into account in parallelogram kinematics for the movement of the covering element 500.

Furthermore, the U-shaped guide groove 704 advantageously allows the lowering element 500 to be lowered in two sliding directions of the sliding leaf 200 of the sliding door, as is shown in FIG Figures 9a and 9b shown, and not only in a sliding direction of the sliding leaf 200.

In 8 a section of a running rail 300 with a single cover element 500 in the raised state, two spring mechanisms 600 and two link guides 700 is shown. The cover element 500 has a wedge-shaped extension 505a, b at each of its two ends. The link guides 700 are arranged here in alignment with a set of guide rollers 312a, b. The wedge-shaped extension 505a, b serves as a lowering aid.

Several cover elements 500 can be arranged one after the other as well as more than one spring mechanism 600 and more than one link guide 700 in the running rail 300 .

In Figure 9a a section of a running rail 300 with a single cover element 500 in the lowered state to the left, two spring mechanisms 600 and two link guides 700 is shown. The state lowered to the left results when a sliding leaf 200 is pushed from the right to the left and the lowering element 500 is thereby brought into its lowered state. The cover element 500 also has a wedge-shaped extension 505a, b at each of its two ends.

In Figure 9b is the cover element 500 -analogous to the cover element 500 in Figure 9a - Shown in a state lowered to the right. The state lowered to the right results when the sliding leaf 200 is pushed from left to right and the lowering element 500 is thereby brought into its lowered state. It can be clearly seen that the guide rollers 312a, b each reach through the cover element 500, so that the wing 200 moved above the cover element 500 is guided on the guide rollers 312a, b.

In the Figures 10a to 10p a lowering process of the lowering element 500 in several stages is shown in each case as an example. The sliding leaf 200 or a roller 203 attached to the sliding leaf 200 slides along the wedge-shaped projection 505a, b. As a result, the cover element 500 is successively pressed into the lowered state against the force of the spring mechanism(s) 600, so that the sliding leaf 200 can be pushed over the lowering element 500.

In an embodiment variant of the invention that is not shown, the sliding leaf 200 can have guide rollers that roll on guide rails or shafts or guide elements that are designed in a different way. These guide elements are preferably arranged on the base rail 307, but could alternatively also be arranged on the running rail 300. The lowering element 500 is then designed accordingly.

In a further embodiment variant of the invention that is not shown, the cover element 500 is designed in such a way that it only covers the space between the inner webs 311a and 311b of the base rail 307 . Furthermore, it is also conceivable in this context that the cover element 500 has an alternative cross-sectional geometry, so that the cover element 500 can be designed like a grate, for example.

Provision can also advantageously be made for several of the cover elements 300 to be offset from one another in the main extension direction of the running rail 1 and/or for several of the spring mechanisms and/or for several of the link guides to be arranged in the running rail.
