Description

TITLE

SLIDING WALL ARRANGEMENT WITH COVERING ELEMENT

TECHNICAL AREA

The present invention relates to a sliding wall arrangement with at least one wing, which is displaceably mounted in a guide channel of a retractable in a building floor running rail.

STATE OF THE ART

Sliding wall arrangements with at least one wing, which is mounted in a retractable in the building floor running rail and slidable along this, are well known. They allow a wide view and can be produced without thresholds and with a comparatively small frame proportion. Due to the sinking of the lower track in the ground a profile-free transition of the wings to the ground is possible. As a result, a maximum light opening is possible. The wings are usually glazed several times and usually have a circumferential profile.

In such sliding walls good thermal insulation and sound insulation is essential. Therefore, the rails of such sliding walls are usually made of at least two profiles, such as aluminum profiles, which are firmly connected to each other via heat-insulating fasteners. The separation by such usually made of plastic connecting elements allows effective thermal separation of the two profiles, in each of which a wing is slidably guided. In countersunk tracks also an effective drainage is essential.

Increasingly, such sliding walls are created with thicker wings, which is still a to enable better heat and sound insulation. Accordingly, the guide channels must be made wider so that these wider sliding walls can be sunk in these. However, such wide guide channels are rather undesirable, especially from an aesthetic point of view. It is also possible in principle that such wide guide channels are unfavorable when using shoes with narrow heels. Depending on the country, there are also standards for handicapped-accessible construction, which limit the dimensions of thresholds and floor openings.

In the prior art, therefore, for example by JP 2001311362 and DE 28 44 877 guide channels have become known which have a flap, which are folded down with the door open and which cover the upper opening of the corresponding guide channel. To close the door again, this flap must be pivoted again, which of course can be complicated and undesirable.

JP2005133298 shows a sliding wall, in which the guide channel is covered by steel bands, which are mounted on both sides of the sliding wall. When opening the door, the steel strip lying in the opening direction is bent back by 180 ° downwards at the outer end of the guide channel and returned to a part of the guide rail arranged below the guide channel. Further such solutions are disclosed in US 2015/0033633 Al and in WO 2015/150991 Al.

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

The Possibilities in such systems with retightened cover band are limited. For example, such a solution can not be used in sliding wall arrangements in which more than one displaceable wing per guide channel is provided. In sliding wall arrangements in which the guide channel is designed to be particularly long in relation to the displaceable wing, It may be difficult to provide enough storage space for the masking tape. In addition, the displacement and deflection of the long cover strip, in particular in the event of the penetration of dirt particles, can lead to the smooth running of the displaceable wing being impaired due to frictional forces.

PRESENTATION OF THE INVENTION

The invention has for its object to provide a sliding wall arrangement of the type mentioned, which avoids the disadvantages mentioned. The sliding wall should thus be feasible even with very wide guide channels, for example with a width of 50 mm and more, without causing aesthetic or other problems here.

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

Thus, the present invention provides a sliding wall assembly having

at least one wing with a bottom edge,

a running rail, which is retractable in a building floor and at least one guide channel, in which the at least one wing is slidably mounted at the bottom, and

at least one cover element which serves to cover the at least one guide channel when the guide channel is released from 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 is away movable.

The at least one cover element can thus be lowered into the guide channel in order to to allow a displacement of the wing or the wing over the cover. For storage of the cover in the lowered state thus 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 moved along its entire longitudinal extent and as a whole raised or lowered, that is moved upwards or downwards. The raising and lowering movement therefore in particular has a component which is perpendicular to the longitudinal direction of the cover element. It is possible that the lowering element is moved along its longitudinal direction by a certain distance. However, the travel path 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 on the order of magnitude of the movement perpendicular to the longitudinal direction. The longitudinal direction or the direction of the longitudinal extension of the cover member usually corresponds to the longitudinal direction or direction of the longitudinal extension of the running rail.

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

Preferably, the cover member in the raised state has the same overall shape as in the lowered state, that is, it is neither bent, compressed, reduced, enlarged or otherwise reshaped. The cover is advantageously formed integrally as a whole.

The displaceable wing may 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 sliding wing usually has at least one glass pane on. Advantageously, the guide channel is covered in the region of the wing by the wing and in the areas outside the wing of the at least one cover.

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

The lowering of the cover can be achieved in various ways. Preferably, however, a spring mechanism is arranged in at least one guide channel, which acts on the at least one cover element with a spring force directed toward the raised state. The lowering is then preferably effected by means of the force acting on the cover weight of the wing when it is moved over the at least one cover member away. The spring mechanism advantageously has one or more torsion 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 may 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 in this. The at least one wing then usually has on its underside at least one tread, which is moved when moving the wing on the rollers, so that they roll on the tread. Of course, the rollers may be mounted in an alternative embodiment also on the underside of the at least one wing, and in at least one guide channel may be provided one or more treads on which the rollers can roll when moving the wing. The arranged in the guide channel tread (s) can also be considered as a guide in such an alternative embodiment.

In the raised state, the cover is arranged above the guide means and covers this advantageous upwards. In the lowered state, the cover member is preferably surmounted by the guide means upwards. Preferably, in the lowered state, the cover element is thus lowered into the guide channel at least so far downwards that it is projected upward from the uppermost point of the guide means. The at least one wing can thereby be displaced beyond the at least one covering element and simultaneously supported by the guide means.

Advantageously, the cover element has at least one recess in order to allow a passage in the lowered state through the guide element through the cover element. The recess may be formed laterally open or be completely enclosed laterally by the material of the cover. The provision of at least one recess in the cover allows a larger coverage of the guide channel in the raised state of the cover. Preferably, a first and a second guide means are arranged in the guide channel, which both serve to support the at least one wing and advantageously spaced and extend parallel to each other along the direction of displacement of the wing. Both the first and the second guide means may each be one or more rollers. Advantageously, two parallel and extending in the longitudinal direction of the track rows of successively arranged rollers are provided, via which the at least one wing is displaced so that the wing can roll with its underside in sequence on the rollers. In such an embodiment, the rollers may of course also be attached to the underside of the wing, and in the guide channel may be provided for the rollers one or more running surfaces.

In a particularly preferred embodiment, the at least one cover element is connected to the running rail such that the at least one cover element is movable 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 is always arranged parallel to the running rail, which brings obvious aesthetic and functional advantages. A guided parallel displacement of the cover relative to the running rail can be achieved in a variety of ways, such as by means of a slotted guide. In a preferred embodiment, however, at least one support block is arranged to be movable in the at least one guide channel. This at least one support block is preferably movably connected to the running rail and the cover, that the guided movement, in particular parallel displacement, of the cover is predetermined by the at least one support block. The at least one support block is also advantageous for receiving weight forces that act on the at least one cover element in the raised state, and preferably also in the lowered state. In this way, much more weight can be absorbed by the lowering element.

Advantageously, the at least one bearing block on a rounded trained rolling surface to allow a uniform rolling of the support block when the at least one cover is brought from the lowered in the raised state or from the raised to the lowered state. In addition, the at least one support block preferably has a substantially planar design footprint. By means of the plan trained standing area, the weight forces can be well diverted and unwanted further movement of the support block is prevented.

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

In order to move the at least one cover 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 mounted on the wing.

Optimum smoothness of the at least one wing can be achieved if Rollers are mounted at its lower edge, which roll when moving the wing on an upper side of the at least one cover and thereby hold this in its lowered state. Preferably, a plurality of cover elements are provided 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 meshing of cover elements arranged one behind the other, the cover elements, but at least one of the cover elements, in certain embodiments may have a first end with a projecting along a first direction of displacement of the wing part and a second end with a Have recess which extends along a direction opposite to the first displacement direction of the second displacement direction of the wing and is designed to be open to the outside. The recess is preferably formed complementary to the projecting part.

FIG. 1 shows a sliding wall arrangement known in the prior art. FIGS. 2 to 13 show a first embodiment of a sliding wall arrangement according to the invention. FIGS. 14 and 15 show further embodiments of sliding wall arrangements according to the invention. Similar or equivalent elements of the various embodiments of sliding wall arrangements are each provided in FIGS. 1 to 15 with the same reference number.

The sliding wall arrangement of the prior art shown in FIG. 1 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 profiled rail whose cross-section over the entire longitudinal extension of the running rail 1 is identical. The two mutually parallel guide channels 1 1 and 12 are bounded laterally outwardly by a respective side web 13 and are separated by a central web 14 from each other. The two side webs 13 and the central web 14 extend parallel to each other and perpendicularly from a main portion 15 from the top. The main portion 15 thus connects the side bars 13 and the central web 14 with each other.

The running rail 1 is recessed in a building floor such 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 lie flush with the bottom surface B. The two guide channels 1 1 and 12 are each used for the storage of one or more wings 2, which are guided along the longitudinal direction of the guide channels 1 1, 12 are displaceable. The wings 2 may in particular be wings of a sliding window or a sliding door. Due to the dimensioning of the guide channels 1 1, 12 and because of the sunken arrangement of the track rail 1 in the building floor, a part of a frame 22 extending along the underside of the wing 2 can be completely received by the respective guide channel 1 1 or 12. For the viewer, the lower part of the frame 22 is thus largely invisible and the width of the light opening when viewed through the frame 22 held Glass panes 21 maximized.

The lower part of the frame 22, which is disposed within the guide channel 1 1 and 12, has an upwardly open, upper channel 23, which serves to receive and hold the glass panes 21. In the areas between the frame 22 and the glass sheets 21 sealing elements 24 may be provided.

The underside of the frame 22 forms two mutually parallel running surfaces 25 and 25 ', which are each arched in the present case. Between the two running surfaces 25 and 25 ', a downwardly open, lower channel 26 may be provided.

In order to guide the wings 2, a base rail 3 with rollers 4 and 4 attached thereto is mounted in the guide channels 11 and 12, respectively. The base rails 3 are formed as profile rails with a along the longitudinal extent of the base rail 3 each substantially invariable cross-section. They each have a main section 31, from which extend in the vertical direction and parallel to each other two outer webs 32 and two inner webs 33 downwards. The outer webs 32 and the inner webs 33 each extend equally far down and end with their lower end faces on the top of the main portion 15 of the track rail first

The rollers 4 and 4 'are mounted at regular intervals along the longitudinal extent of the track rail 1 in two parallel rows freely rotatable between the outer webs 32 and the inner webs 33. The first row of rollers 4 forms a first filling means and the second row of rollers 4 'a second guide means for guiding the blade 2. The rollers 4 and 4' are respectively mounted on roller axles 35 and 35 ', each extending from an external web 32 extend to an inner web 33. Between the inner webs 33 of the base rail 3 remains a void, which is unused.

In the main portion 31 of the base rail 3, recesses 34 are provided above the roller axles 35, 35 ', which are penetrated by the rollers 4, 4', to allow a resting of the treads 25, 25 'on the rollers 4, 4'.

The radial outer surfaces of the rollers 4, 4 'are due to their radially inwardly directed curvature complementary to the running surfaces 25 and 25' of the frame 22 is formed. When moving the blade 2, the running surfaces 25 and 25 'of the frame 22 are on the rollers 4, 4', which roll on the running surfaces 25, 25 'and thus ensure a simple displaceability of the wing 2. By the intermeshing of the treads 25, 25 'and the treads 4, 4' with their surfaces complementarily formed due to the respective curvature, a lateral, i. achieved perpendicular to the direction of acting guide of the wing 2.

The base rails 3 may be fixedly connected to the track rail 1, as in particular to be welded in each case with this. The running rail 1 can also be formed integrally with the base rails 3.

The sliding wall arrangement of the prior art shown in FIG. 1 has the considerable disadvantage that the guide channels 11, 12 are exposed outside the displaceable wing 2. As a result, dirt can easily penetrate into the guide channels 11, 12. In addition, the guide channels thereby form a trip hazard and are unfavorable, especially for heel shoes.

In the embodiment according to the invention shown in FIGS. 2 to 13, 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 raised state covers the cover 5, the guide channel 1 1 or 12, which would otherwise be exposed, from, as shown in Figure 2 on the left side of the guide channel 1 1. In order to allow a displacement of the wing 2 on the cover 5 away, this is brought into the lowered state, as shown in Figure 2 on the right side of the guide channel 12. The guide channel 12 is then covered by the wing 2.

The track rail 1 is identical to that of the embodiment of the prior art of Figure 1 is formed. In contrast to the embodiment of the prior art shown in Figure 1, the basically identical trained base rail 3 is here but reversed arranged in the track rail 1, so that the main portion 31 rests directly on the main portion 15 of the track rail 1 and the outer webs 32 and the inner webs 33 extend from the main portion 31 upwards. In contrast to the base rail of Figure 1, that of Figure 2 has no recesses 34. The rollers 4, 4 'are arranged here so that they project beyond the free ends of the inner webs 33 and outer webs 32 upwards and thereby allow a bearing of the running surfaces 25, 25' of the wing 2.

The cover 5 is formed as a U-shaped profile rail with a main portion 51 and two of this parallel to each other and in the vertical direction downwardly extending outer webs 52. The top of the main portion 51 comes in the raised state of the cover 5 is substantially flush lie with the bottom surface B and covers the guide channel 11, 12 while largely from the top. The outer webs 52 abut 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 5 is achieved from the raised to the lowered state and vice versa. In addition, the arranged under the cover 5 parts are better protected due to the outer webs 52 from the ingress of dirt particles.

In the main portion 51 of the cover 5 recesses 54 are provided, which allow a projection of the rollers 4, 4 'in the lowered state of the cover 5. The cover 5 is thus arranged in the raised state above the rollers 4, 4 'and in the lowered state below the running surfaces 25, 25' of the frame 22. Between the two outer webs 52 of the cover 5, two inner webs 53 each extend perpendicularly from the main portion 51 downwards. The inner webs 53, however, extend less far downwards than the outer webs 52. The inner webs 53 are at regular intervals along the longitudinal extent of the cover element 5 by transverse axes 50 and 56, whose functions will be explained, interconnected.

The top of the main portion 51 of the cover 5 has a slightly raised center portion, which serves for rolling of the rollers 28, which are mounted on the underside of the frame 22 when moving the wing 2. The rollers 28 are each freely rotatably mounted in the lower channel 26 of the frame 22 via a transverse axis 27. The wing 2 is otherwise identical to the embodiment of the prior art shown in FIG.

The area of the base rail 3 between the two inner webs 33 is used in the present inventive embodiment for accommodating a spring mechanism 'with one or more leg springs 6. The spring mechanism urges the cover element 5 with a spring force which presses the cover element 5 in the direction of its raised state. The one or more leg springs 6 each have two upper legs 61, the end portions of which, as can be clearly seen in particular in a combination of FIGS. 2 and 5, abut respectively on the transverse axis 56 and are bent around them. Two lower legs 62 of the leg spring 6 are each flat on the top of the main portion 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 5 is thus brought into its raised state and held in this. When the wing 2 is pushed over the cover 5 away, the cover member 5 is pressed by the weight of the wing 2, which is transmitted via the rollers 28, against the spring force in the lowered state and held therein. By rolling the rollers 28 on the main portion 51 of the cover 5, the mutual friction between the wing 2 and the cover 5 during movement of the wing 2 is minimized.

In the area between the inner webs 33 of the base rail 3 are also Support blocks 7 arranged, which are connected on the one hand with the cover 5 and on the other hand with the base rail 3 movable. The connection to the cover 5 is made in each case via a transverse axis 50, which projects through the support block 7, and about which the support block 7 is freely rotatable. The connection to the base rail 3 takes place in each case via a transverse axis 37, which extends between the two inner webs 33 of the base rail 3, and about 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 formed identically, have in the side view, as shown for example in the in Figure 5, an elongated, extending from the transverse axis 37 to the transverse axis 50 on the form. A in the raised state of the cover 5 in the longitudinal direction of the track rail 1 facing first side of the support block 7 is formed substantially flat and merges in each case in the areas of the axial holes in a rounded surface, wherein in the region of the transverse axis 50 is semicircular around the corresponding axle hole extends around. The one in the region of the transverse axis 37 extends over an angular range of about 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 plan trained surface forms a base 73 of the support block. The paragraph 71 has a triangular shape in the side view, which is integrally connected along one of its side lines with a plan formed second side of the support block 7. The second side of the support block 7 is formed between the two rounded surfaces of the support block 7 and turned in the opposite direction to the first side.

From the figure 5 is clearly visible how the cover member 5 is supported in the raised state of two support blocks 7 and held by an interposed leg spring 6 in this position. The support blocks 7 stand with their support surfaces 73 on the top of the main portion 31 of the base rail 3. Due to the paragraph 71 tilting of the support blocks 7 is prevented, which otherwise take place due to the existing in this position of the cover 5 possibly existing spring force of the leg spring 6 could. When moving the wing 2, the cover 5 is pressed by means of stop of the wing 2 at a longitudinal direction of the track rail 1 end opposite to the spring force caused by the leg spring 6 horizontally along the longitudinal direction of the track rail 1 and down in the guide channel 1 1, 12 pressed ( FIGS. 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 about 90 °, wherein the rolling surfaces 72 roll on the main portion 31 of the base rail 3. The lowering of the cover 5 is possible as far as the paragraphs 71 of the support blocks 7 abut on the underside of the main portion 51 of the cover 5. Due to the weight of the wing 2, the cover 5 is held against the spring force in the lowered state. The cover 5 is then below the lower edge of the wing 2 and completely within the guide channel 1 1, 12 of the track rail 1 (see Figure 6). Due to the support blocks 7, the movement of the cover 5 is carried 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 the bottom surface B. Furthermore, the support blocks 7 allow a high load of the cover 5 in the raised state of the cover 5.

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

If the wing 2 is only partially above the cover 5, a certain opening of the track 1 remains outside the wing 2. The cover 5 is indeed in the lowered state, the wing 2 is then not in all However, in the lowered state the covering element 5 considerably reduces the exposed opening of the running rail 1 and even then covers the parts arranged in the running rail, in particular the torsion springs 6, the support blocks 7 and the base rail 3, which is itself is aesthetically appealing to the viewer. The cover 5 thus causes even in the lowered state still some coverage of the guide channels 1 1, 12. By the stop of paragraphs 71 of the support blocks 7 on the underside of the cover 5, as shown for example in Figure 6, is also in lowered state a high weight load of the cover 5 possible.

As can be seen from FIG. 9, in the case of a guide channel 11, 12 a plurality of covering elements 5 arranged one behind the other can be provided, which are pressed downwards in the lowered state upon displacement of the wing 2. The more cover elements 5 are provided, the shorter the areas between the wing 2 and the next, in the raised state cover member 5. It is also easily possible that a plurality of sliding wings 2 in a single guide channel 1 1, 12 are stored ,

During the transition from the raised to the lowered state, the cover element 5 is moved over a certain distance along the longitudinal extension of the running rail 1 due to the tilting movement of the support blocks 7. In order to take this circumstance into account, in particular in the case of a plurality of 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 can be seen in FIGS. 10 and 12.

In order to enable a continuous covering and meshing of cover elements 5 arranged one behind the other, these each advantageously have in a first end region a projecting center part 59 on which the roller 55 is mounted, and in a second, opposite end region a longitudinal direction of the cover element 5 open recess 57, which is complementary to the acting from center part 59 of the adjoining cover 5 is formed. See FIGS. 11 and 13. FIG. 14 shows a second embodiment of a sliding wall arrangement according to the invention. In contrast to the first embodiment shown in FIGS. 2 to 13, here the cover element 5 does not extend beyond the outer webs 32 of the base rail 3, but is located entirely within the inner webs 33 of the base rail 3. Also in this case in comparison with the first embodiment constructively somewhat simpler embodiment, however, a certain coverage of the track rail 1 and reduction of the exposed guide channel 11, 12 is achieved. The accommodated in the base rail 3 spring mechanism and the support blocks are also well covered by the cover 5 here.

A third embodiment of a sliding wall arrangement according to the invention is shown in FIG. In this embodiment, a plurality of lamellar and arranged cover elements 5 are provided, which are arranged edgewise in the guide channel 11 and 12 respectively. Between the cover elements 5, instead of just one thick, a plurality of, specifically two, thin support blocks 7 are arranged parallel to one another, which are respectively penetrated by a common transverse axis 50 and a common transverse axis 37. The transverse axes 50 also hold together the cover elements 5 arranged parallel to one another. Again, a cover of the running rail 1 and reduction of the exposed guide channel 1 1, 12 is achieved by the cover 5.
