Description

The invention relates to a sliding wall system with at least one door leaf element and at least one display device for indicating a locking state of the door leaf element.

Sliding wall systems and their door leaf elements are known, for example, in multi-leaf entrance doors, sliding wall elements used as room dividers or wall elements in front areas of buildings, especially in restaurants and shops, to keep the shop open or closed according to the weather. In this case, the individual wing elements can be moved to be parked in a side position so that there is no hindrance to the entering public traffic. Furthermore, it is known to provide a door within these sliding wall elements. In order to provide a desired function of the door leaf element, a locking mechanism is provided which can prevent the displaceability and / or the pivotability of the door leaf element. However, such a sliding wall system has the disadvantage that the respective locking state of the door leaf element is not immediately recognizable.

Such a sliding wall system is for example off EP 2 784 255 A2 known. Out US 5 437 173 A a lock with a display device with three different display positions is known.

It is therefore an object of the present invention to provide a sliding wall system with at least one locking mechanism available, which is compact and in which the locking state of a door leaf element is easily recognizable.

According to the invention this object is achieved by a sliding wall system, comprising: at least one ceiling guide, at least one door leaf element with a door rail and a fastening profile, wherein the door leaf element is slidably and / or pivotably arranged in the at least one ceiling guide, at least one locking mechanism with a locking element which between a first position, a second position and a third position on or integrated in the fastening profile is movably arranged to allow a locking between the fastening profile and the ceiling guide and / or between the fastening profile and the door rail, and at least one display device which at least partially coupled is with the locking element, and indicates the locking state of the door leaf element, wherein the display device comprises a first display element and a second display element, wherein the first display Lement on the locking element is rotatably mounted and the second display element rotatably coupled to the locking element, and wherein the first display element and the second display element overlap at least partially and the locking mechanism has a third housing component, which is arranged on the mounting profile, wherein the third housing component has a first recess and a second recess, through which a relative position between the first display element and the second display element is displayed, wherein the first display element through the first recess and the second recess visible and in the first recess and / or in the second recess through the second Display element is concealable.

The sliding wall system according to the invention has the advantage that it is detected in a user-friendly, simple and quick way, in which of the following locking states is a sliding and / or pivoting door leaf element: (a) blocks mobility and free pivoting, the door leaf element can be used as a door can, (b) free movement and blocking pivoting, wherein the door leaf element can only be moved, or (c) blocking slidability and pivoting, wherein the door leaf element is fixed. The recognition of the locking state of the door leaf element at a glance gives the user the reassuring feeling of security more quickly. Furthermore, the operation is enormously simplified, since only one element must be adjusted in order to effect all three positions.

Preferably, in the first position of the locking element, the displaceability of the door leaf element in the ceiling guide is blocked. More preferably, the pivotability of the door rail is blocked in relation to the fastening profile in the second position of the locking element. Particularly preferably, the displaceability and the pivotability of the door leaf element in the ceiling guide are blocked in the third position of the locking element. Thus, a clear separation of the functions of the door leaf element is provided, whereby an error-free detection of the locking state is possible.

Advantageously, the locking element on the fastening profile, in particular about an axis of rotation, which is perpendicular to the door leaf element, rotatably arranged, and to be converted by rotation in the first position, the second position and the third position. This allows a compact and simple construction and operation of the locking mechanism and the display device.

Advantageously, the locking element comprises a Teilzahnradelement which is directly actuated by a screw. The direct engagement of the worm and the Teilzahnradelements without a Zwischenzahnradelement allows a compact construction of the locking mechanism. The self-locking of the screw prevents the locking element from coming loose from a locked position by itself.

Furthermore, it is advantageous if the locking mechanism comprises a first housing component, which is connected to the ceiling guide, and in particular has a stop on which the locking element rests in the first position. The first housing component is preferably positioned on the outside of the ceiling guide, which significantly simplifies installation.

Further preferably, the locking mechanism comprises a second housing member, which is connected to the door rail, and a groove, in which engages the locking element in the second position. The second housing component is preferably positioned on the outside of the door rail, which significantly simplifies installation.

Preferably, the locking element has an arm portion which engages in the second position of the locking element in the groove and engages around a pin which is arranged parallel to the axis of rotation of the locking element in the second housing component. Thus, a stable locking is achieved.

More preferably engages in the third position of the locking element, the locking element partially in the first housing component and partially in the second housing component. By providing only one locking element for the locking in all three positions, the construction and operation is simplified, whereby assembly chain errors can be avoided.

According to the invention, the display device has a first display element and a second display element, wherein the first display element rotatably disposed on the locking element and the second display element rotatably coupled to the locking element, wherein the first display element and the second display element overlap at least partially. Particularly preferably, the first display element is fixedly arranged on the second housing component, wherein the second display element rotates with the locking element. The respective degree of overlap of the first display element and the second display element indicates the respective locking state of the door leaf element.

According to the invention, the locking mechanism has a third housing component, which is arranged on the fastening profile, wherein the third housing component has a first recess and a second recess, through which a relative position between the first display element and the second display element is indicated, wherein the first display element by the first recess and the second recess visible and in the first recess and / or in the second recess by the second display element can be covered. The display device according to the invention thus indicates the state of the locking mechanism with a clear traffic light system. The first recess indicates whether the door leaf element can be used as a door. The second recess indicates whether the door leaf element can be moved in the ceiling guide. The provision of two recesses facilitates recognition of the locking state of the door leaf element.

Advantageously, the first display element is concealed in the first position of the locking element in the first recess by the second display element, concealed in the second position of the locking element in the second recess by the second display element, and in the third position of the locking element in the first recess and hidden in the second recess by the second display element.

Furthermore, it is advantageous if the locking element has a reinforcing region, which is located in the first position in the first housing component, in particular bears against a stop of the first housing component. The reinforcing area protects the locking element against high actuating forces.

Furthermore, the first housing component and / or the second housing component preferably has an access recess, through which the worm can be actuated. As a result, the screw is operated in a simple manner by means of a tool. In addition, thus, the locking state of the door leaf element can only be changed by authorized persons.

Fig. 1 shows a perspective view of a sliding wall system 1 according to the present invention. The sliding wall system 1 according to the invention comprises a ceiling guide 2 and four door leaf elements 3, which are arranged in the longitudinal direction L of the sliding wall system 1 in the ceiling guide 2 side by side. All door panels 3 have the same width z. The ceiling guide 2, which is designed as a one-piece rail 10, has a length which corresponds to a four times the width z of the door leaf elements 3. Alternatively, the ceiling guide 2 may be composed of a plurality of ceiling guide elements.

Furthermore, the sliding wall system 1 is arranged on a frame 9. In particular, the ceiling guide 2 is provided on an upper part of the frame 9, which is attached to a ceiling, not shown, of a building. Alternatively, the ceiling guide 2 may be attached directly to the ceiling of the building. A lower part of the frame 9 is fixedly connected to a floor of the building, also not shown.

In particular, the sliding wall system 1 of the invention Fig. 1 a first door leaf element 3a, a second door leaf element 3b, a third door leaf element 3c and a fourth door leaf element 3d, which may be provided with certain functions. The first door leaf element 3a and the fourth door leaf element 3d are pivotally mounted in the ceiling guide 2 and rotatably mounted on the floor, wherein the second Door leaf element 3b in the ceiling guide 2 can only be moved. Furthermore, the third door leaf element 3c is arranged pivotably and displaceably in the ceiling guide 2. Thus, the first door leaf element 3a and the fourth leaf element 3d serve as rotary or pendulum wings, the second leaf element 3b as a sliding leaf and the third leaf element 3c as a rotary sliding wing.

All door leaf elements 3 each have a fastening profile 4, two door rails 5 and a glass pane 34, which are arranged between the door rails 5. The fastening profiles 4, the door rails 5 and the glass panes 34 are identical in all door leaf elements 3. The one door rail 5 of each door leaf element of the door leaf elements 3a, 3b, 3c and 3d is arranged on one of the ceiling guide 2 end facing and the other at a bottom facing the end.

Furthermore, the sliding wall system 1 comprises three locking mechanisms.

The third door leaf element 3c has a locking mechanism 6, which is a two-sided locking mechanism. As a result, a rotation of the door rails 5 and the glass pane 34 of the third door leaf element 3c, which are firmly connected to one another, can be prevented with respect to the fastening profile 4 of the third door leaf element 3c. Further, by the two-sided locking mechanism 6, a displacement of the third door leaf element 3c in the ceiling guide 2 in a direction of displacement V can be blocked. The displacement direction V is determined by the shape of the ceiling guide 2. Here, the shift direction V corresponds to the longitudinal direction L of the sliding wall system 1. The structure and function of the two-sided locking mechanism 6 will be described later with reference to FIGS FIGS. 20 to 24 described.

In all the door leaf elements 3, a three-sided locking mechanism 8 is provided, which causes the locking in three directions. The three-sided locking mechanism 8 allows locking of a door leaf element 3 in an adjacent door leaf element 3, the frame 9 or the floor and has an additional closing function.

On the first door leaf element 3a a one-sided locking mechanism 7 is arranged, which prevents a rotation of the first door leaf element 3a with respect to the ceiling guide 2.

However, since the one-sided locking mechanism 7 and the three-sided locking mechanism 8 are not part of the present invention, they will not be explained in detail here.

The Fig. 2 and 3 show a portion of a ceiling guide 2 of a sliding wall system 1 according to the present invention. As can be seen from these figures, the ceiling guide 2 is composed of three rails 10, in particular a first rail 10a, a second rail 10b and a third rail 10c, and a switch 11, which is formed as a branch 15 composed.

The branch 15 has three connection surfaces, to which the three rails 10a, 10b and 10c are connected. The rails 10 a, 10 b and 10 c are connected to the branch 15 by means of a plurality of connecting devices 18. Each connecting device 18 has a plug-in element 19, which is inserted into a groove 20 of one of the rails 10 and into a groove 21 of the switch 11, and is screwed into the rails 10 and the branch 15. In particular, in the Fig. 2 a first connection device 18a, a second connection device 18b and a third connection device 18c. The first rail 10a is connected to the switch 11 by means of the first connection device 18a, which has a first plug-in element 19a, a first groove 20a formed in the first rail 10a, and a first groove 21a formed in the switch 11 connected. The second connection device 18b has a second plug-in element 19b, a second groove 20b formed in the second rail 10a, and a second groove 21b formed in the switch 11 and connects the second rail 10b to the switch 11. Via the third connection device 18c, which consists of a third plug-in element 19c, a third groove 20c formed in the third rail 10c and the second groove 21b of the switch, the third rail 10c is connected to the switch 10. In the Fig. 2 and 3 Furthermore, a roller carriage 23 is shown in the ceiling guide 2, which with respect to the Fig. 7 to 10 will be described in more detail.

The Fig. 4 and 5a show perspective views of the branch 15. In order to facilitate a deflection of the roller carriage 23 in the ceiling guide 2, the branch 15 has a deflecting element 16. The deflecting element 16 is arranged on one of the building ceiling facing inside 17 of the branch 15. In particular, the deflecting element 16 is screwed into the branch 15 by means of steel screws ( Fig. 4 ). Furthermore, the deflecting element 16 is made of plastic, in particular polyoxymethylene. The rails 10 each have a first slot 12. The branch 15 has two second slots 13 which communicate with each other. In the assembled state of the ceiling guide 2, the first slots 12 of the rails 10a, 10b and 10c join the second slots 13 of the branch 15 and form a continuous slot profile (FIG. Fig. 3 ).

Fig. 6 shows a switch 11 in the form of a sheet 14 according to the present invention. Sheets are used on sliding walls when a sliding direction of a door leaf element is to be changed by about 90 degrees. This may for example be the case when the door leaf element has to be moved to a parking position of the sliding wall system.

The sheet 14 has two connection surfaces, to which two rails 10a and 10b can be connected, wherein the sheet 14 is formed with a quarter-circle-shaped slot 13.

The branch 15 and the bow 14 are formed in the basic form as U-shaped profiles.

The rails 10 and the switches 11, from which the ceiling guide 2 is composed, are manufactured according to the present invention by means of an extrusion process. In particular, the rails 10 and the points 11 are extruded from the same material. The switches 11 are each formed from an extruded in cross-section substantially rectangular or square extruded body. The rails 10 and the switches 11 have adjacent visible surfaces with a substantially same extrusion direction. Thus, according to the invention, a very similar or identical visual impression is achieved with these visible surfaces.

In Fig. 3 For example, a first viewing surface 91, a second viewing surface 92 and a third viewing surface 93 of the branch 15 and a first viewing surface 94 and a second viewing surface 95 are shown in each of the rails 10. The rails 10 and the switch 11 have further visible surfaces, but which in Fig. 3 are not apparent. The number of visible surfaces depends on the shape of a rail or a switch and their arrangement in a sliding wall system.

The switch 11 are machined starting from the extruded body, wherein the adjacent to the rails 10 visible surfaces of the switch 11 are not machined.

In order to further improve the overall appearance of the ceiling guide 2, all visible surfaces of the rails 10 are not machined. As a result, the ceiling guide 2 produces a uniform and harmonious aesthetic appearance.

The rails 10 each have a first Außenflächenrillung and the switch 11 on a second Außenflächenrillung on their adjacent visible surfaces in the extrusion direction, which has a substantially parallel to the direction of displacement V of a door leaf element 3 groove orientation. External surface grooving or grooving is to be understood as meaning a substantially line-shaped surface structure comprising a plurality of parallelly arranged linear depressions, which are produced by the extrusion process and influence the surface quality and the visual impression of a surface.

The scoring of the adjoining visible surfaces preferably has a roughness R _{a of} from 0.1 μm to 2.0 μm, furthermore preferably from 0.2 μm to 1.6 μm, very particularly preferably from 0.2 μm to 1 μm according to DIN EN ISO 4287 in the transverse direction to the groove alignment.

In a preferred embodiment, all visible surfaces of the switch 11 and the rails 10 have a roughness R _a of 0.1 microns to 2.0 microns, further preferably from 0.2 microns to 1.6 microns, most preferably from 0.2 microns up to 1 μm, measured according to DIN EN ISO 4287 in the transverse direction to the groove orientation.

According to a most preferred embodiment of the invention, the deviation in the roughness of adjacent visible surfaces of the switch 11 and the rails 10, preferably all visible surfaces, in an interval R _a from 0.1 .mu.m to 2.0 .mu.m, further preferably from 0, 2 μm to 1.6 μm, very particularly preferably from 0.2 μm to 1 μm, <10%, preferably <5%.

It is further highly preferred that adjacent viewing surfaces of the rails 10 and the switch 11, preferably all visible surfaces, have a substantially identical roughness in the transverse direction to the groove orientation.

The visual impression can be further improved if the adjacent visible surfaces of the switch 11 and the rails 10 a surface roughness R _a parallel to the extrusion direction of 0.1 .mu.m to 3 .mu.m, preferably from 0.2 .mu.m to 2 .mu.m, more preferably from 0 , 75 μm to 1.8 μm, measured according to DIN EN ISO 4287.

Particularly preferably, all visible surfaces of the switch 11 and the rails 10 have a surface roughness R _a parallel to the extrusion direction of 0.1 .mu.m to 3 .mu.m, preferably from 0.2 to 2 .mu.m, particularly preferably from 0.75 .mu.m to 1.8 .mu.m, measured according to DIN EN ISO 4287.

In a most preferred embodiment, it is further preferred that the deviation of the surface roughness R _a parallel to the extrusion direction of at least two adjacent visible surfaces of the rails 10 and the switch 11, preferably of all visible surfaces selected from the interval R _a of 0.1 microns to 3 .mu.m, preferably from 0.2 .mu.m to 2 .mu.m, <10%, in particular <5%.

In a further highly advantageous further development of the invention, the surface roughness R _{a is} substantially identical to the extrusion direction of at least two adjacent visible surfaces of the rails 10 and the switch 11, preferably all visible surfaces.

Furthermore, it is to further improve the visual impression of advantage that at least the adjacent visible surfaces of the switch 11 and the rails 10 a gloss level of 1 GE to 50 GE, preferably 5 GE to 25 GE, measured at an angle of 60 ° to DIN 53778 have.

Furthermore, all visible surfaces of the switch and the rail preferably have a gloss level of 1 GE to 50 GE, preferably 5 GE to 25 GE, measured at an angle of 60 ° according to DIN 53778.

In a most preferred embodiment of the invention, the deviation of the gloss levels selected from the interval 1 GE to 50 GE, preferably 5 GE to 25 GE, the adjacent visible surfaces <10%, particularly preferably <5%.

According to a further preferred embodiment of the invention, the mutually adjacent viewing surfaces have a substantially identical degree of gloss selected from the interval 1 GE to 50 GE, preferably 5 GE to 25 GE on.

How out Fig. 5b can be seen, the switch 11 is formed as a hexagonal body. The hexagonal shape of the body results in the plan view of the switch 11 from a hexagonal base surface, wherein at least three of the six sides of the base surface equally high side walls drop vertically defining the height of the switch 11.

A first side and a second side opposite the first side have substantially a same first length l1 and the remaining four sides of the hexagon have a same second length l2, wherein the first length l1 is greater than the second length l2.

In order to provide the largest possible visible surface of the switch 11 optically available, one visible surface has the first length l1 and two further visible surfaces the second length l2. The visible surface of the first length l1 exhibits the same extrusion direction as the visible surfaces of the rails 10 which bear against this surface.

In order to provide a hexagonal shape, which can be processed from the extruded body in the most favorable manner material chopping to the switch 11, two adjacent sides of the second length l2 perpendicular to each other.

To form the entire sliding wall system 1 in an optically harmonic manner, the door rails 5 of the door leaf elements 3 are also extruded and have at least one visible surface having a substantially same extrusion direction as the adjacent visible surfaces of the rails 10 and the switch 11.

To produce the sliding wall system 1 with the ceiling guide 2, a body for the rails 10 and a body for the switch 11 are extruded in any order in each case. The rails 10 and the switch 11 are extruded from the same material.

Subsequently, the extruded body for the switch 11 is machined.

The rails 10 and the switch 11 are assembled to form the ceiling guide 2, so that the rails 10 and the switch 11 have adjacent visible surfaces and the adjacent visible surfaces of the rails 10 and the switch 11 have a substantially equal extrusion direction. Subsequently, a door leaf element 3 in the ceiling guide 2 of the sliding wall system. 1 positioned. Thus, deviations in the visual impression of the rails 10 and the switches 11 can be eliminated.

Fig. 7 shows a roller carriage 23 within the ceiling guide 2 of the sliding wall system 1 according to the present invention. The roller carriage 23 is by means of a connecting element in the form of a pad 30 with a door leaf element 3, such as the second door leaf element 3b of the sliding wall system 1 of Fig. 1 , connected. Characterized the door leaf element 3b in the ceiling guide 2, which is formed of rails 10 and switches 11, slidably arranged. In the sliding wall system 1, a plurality of roller carriage 23 is provided.

The roller carriage 23 of Fig. 7 has a base 24 on which a plurality of rollers 25 and a plurality of guide rollers 26 is arranged. How out Fig. 8 can be seen, the roller carriage 23 comprises four rollers 25 and four guide rollers 26, wherein the rollers 25 are arranged perpendicular to the guide rollers 26. Thus, a fail-safe displacement and guidance of the door leaf element 3b in the ceiling guide 2 can be ensured.

The rollers 25, which are identical, each have a roller body 27 with a roller surface 28, wherein the roller body 27 roll on two running surfaces 29 of the ceiling guide 2.

The main body 24 has a modulus of elasticity at 20 ° C of 70 kN / mm ² to 100 kN / mm ² , preferably about 85 kN / mm ² , according to EN ISO 6892-1: 2009, a shear modulus at 20 ° C of 20 kN / mm ² to 60 kN / mm ² , preferably about 40 kN / mm ² according to DIN 53445, and a density at 20 ° C of 2 g / cm ³ to 7 g / cm ³ , preferably about 6.7 g / cm ³ , according to ISO 1183, on.

The roller body 27 has a modulus of elasticity at 20 ° C of 2 kN / mm ² to 4 kN / mm ² , preferably about 3 kN / mm ² , according to ISO 527-1 / -2 for plastics, a shear modulus at 20 ° C. 0.5 kN / mm ² to 1 kN / mm ² , preferably about 0.8 kN / mm ² , according to DIN ISO 1827: 2010-07 for plastics and a density at 20 ° C of 1 g / cm ³ to 2 g / cm ³ , preferably about 1.4 g / cm ³ , according to DIN EN ISO 1183 on. Furthermore, the roller surface 28 of the roller body 27 has a surface roughness Ra of 0.01 to 3 .mu.m, preferably from 0.05 .mu.m to 2 .mu.m according to DIN EN ISO 4287. Particularly preferably, the roller surface 28 of the roller body 27 is formed isotropically, whereby the roller surface 28 has no direction-dependent surface roughness deviations. The roller body 27 further has a diameter of 16 mm to 20 mm, particularly preferably 18.5 mm. The roller surface 28 of the roller body 27 has a roller surface width of 5 mm to 9 mm, preferably 7 mm. Furthermore, the transition from the roller surface 28 to a side edge of the roller body 27 has a radius of 0.3 mm to 0.7 mm, in particular 0.5 mm.

The roller body 27 also has a water absorption of 0.3% in normal climate according to ISO 62. The water absorption in normal climates refers to the percentage weight gain of a body by water absorption when stored at a temperature of 23 ° C and humidity of 50%. According to the invention, the water absorption of the reel body is kept low in normal climate. A high water absorption leads to a high Abplatten the reel body 27, whereby noise when rolling the roller body 27 of the roller 25 are caused on the tread 29 of the ceiling guide 2.

The roller body 27 also has a water absorption of 1.4% with water storage according to ISO 62. The water absorption in water storage refers to the percentage increase in weight of a body by water absorption when stored in water. The roller body 27 of the roller 25 is formed such that its Water absorption is kept low in water storage. Thus, a flattening of the roller body 27, for example, in a sliding wall system 1, which is arranged in an outer space is reduced. This ensures a quieter operation under different weather conditions.

Furthermore, the reel body 27 has a flattening less than 0.7% with respect to the diameter of the reel body 27 after 8 hours of standstill of the reel body 27. The low allowable flattening of the roller body 27, the smoothness of the sliding wall system 1 according to the invention is significantly increased. The flattening of a reel body 27 is measured by exerting a test load of 200 N in the vertical direction on the reel body 27 arranged on a support. Particularly preferably, the roller body 27 with a diameter of 18.5 mm has a maximum flattening of 0.12 mm after 8 hours of standstill.

The running surfaces 29 of the ceiling guide 2 each have a modulus of elasticity at 20 ° C of 60 kN / mm ² to 80 kN / mm ² , preferably about 70 kN / mm ² , according to EN ISO 6892-1: 2009, a shear modulus at 20 ° C from 10 to 40 kN / mm ² , preferably about 27 kN / mm ² , according to DIN 53445 and a density at 20 ° C of 2 g / cm ³ to 5 g / cm ³ , preferably about 3 g / cm ³ , according to ISO 1183 Furthermore, in each case the running surfaces 29 have a surface roughness Ra parallel to the extrusion direction of 0.05 .mu.m to 1.0 .mu.m, preferably about 0.5 .mu.m, measured according to DIN EN ISO 4287 on. Furthermore, the running surfaces 29 have a surface roughness Ra in the transverse direction to the extrusion direction of 0.7 .mu.m to 1.4 .mu.m, preferably about 0.7 .mu.m, measured according to DIN EN ISO 4287 on. The running surfaces 29 each further have a surface roughness Rz parallel to the extrusion direction of 3 microns to 5 microns, preferably about 3.2 microns, measured according to DIN EN ISO 4287 on. Furthermore, the running surfaces 29 each have a surface roughness Rz in the transverse direction to the extrusion direction of 4 .mu.m to 6 .mu.m, preferably about 4.1 .mu.m, measured according to DIN EN ISO 4287 on. Particularly preferably, a ratio of a surface roughness Ra in the transverse direction to the extrusion direction of the tread 29 to a surface roughness Ra parallel to the extrusion direction of the tread 29 is between 1.1 and 2, preferably between 1.1 and 2.

The running surfaces 29 each have inner surface grooves substantially parallel to the direction of displacement V of the door leaf element 3. As Innenflächenrillung is a substantially linear surface structure of a plurality of parallel line-shaped depressions on the running surface 29 to understand, which is produced by the extrusion process. Furthermore, the running surfaces 29 of the ceiling guide 2 are formed integrally with the ceiling guide 2. Thus, a compact design is possible. Furthermore, potential assembly errors such as inclinations are eliminated, which could cause noise when rolling the door leaf elements 3 in the ceiling guide 2. The ceiling guide 2 has a density of 2 g / cm ³ to 5 g / cm ³ , preferably about 3 g / cm ³ , according to ISO 1183. The running surfaces 29 of the ceiling guide 2 each have a tread width which is greater than the roller surface width of the roller surfaces 28 of the roller body 27.

How out Fig. 9 As can be seen, each of the roller bodies 27 is mounted on the roller carriage 23 by means of a closed ball bearing 31. The roller body 27 has an axis 32 with two knurls 33, by means of which the roller body 27 is secured against rotation on the main body 24 of the roller carriage 23 ( Fig. 9 and 10 ). The axle 32 also serves as an inner ring of the ball bearing 31. The ball bearing 31 has seven balls, which are greased about with lithium soap grease.

Furthermore, the static surface pressure between the roller 27 and the running surface 29 of the ceiling guide 2 is at least 2.5 kg / mm ² , preferably between 2.5 kg / mm ² and 100 kg / mm ² . This leads to a removal of squeaking noises in the process of the door leaf elements 3.

The average travel speed of the roller carriage 23 is between 0.05 m / s and 0.5 m / s, preferably about 0.2 m / s.

Furthermore, the starting torque of a door leaf element 3, which is arranged displaceably in the ceiling guide 2, such as the door leaf element 3b of Fig. 1 , 8N to 15N, preferably 10N to 14N, more preferably 11N to 13N, with a weight of the door leaf member 3b of 175kg. After 100,000 cycles, the starting moment of the door leaf element 3b is still 15N to 21N, preferably 16N to 20N, more preferably 17N to 19N.

By the roller carriage 23 according to the invention and the running surfaces 29 of the ceiling guide 2 according to the invention, a low-noise movement of the sliding wall system 1 is made possible. The abrasion of the roller body 27 is reduced and thus the service life of the roller carriage 23 is significantly increased. In addition, squeaking of the rollers 25 can be eliminated.

Fig. 11 shows a securing device 35 in a built-in sliding wall system 1 state, wherein the securing device 35 is used in a glass breakage for holding the fastening profile 4 of the door leaf element 3. Fig. 12 shows an exploded view of the securing device 35. The securing device 35, for example, in the fourth door leaf element 3d of the sliding wall system 1 of Fig. 1 to be used.

The securing device 35 has a rotary bearing 36, a rotary element 38 and a securing element 40. The pivot bearing 36 is fixedly arranged in the ceiling guide 2. The rotary element 38 is connected to the door leaf element 3 and mounted in the pivot bearing 36. In particular, the pivot bearing 36 is screwed by means of screws 46 in the ceiling guide 2.

Furthermore, the rotary bearing 36 has a sleeve 37, in which the rotary member 38 is rotatably arranged. The rotary member 38 is formed as a pivot having a cylindrical portion and a crowned portion 39, the spherical portion 39 being rotatably positioned in the pivot bearing 36. In particular, the securing device 35 has a support element 43 formed as a block, which is screwed onto the rotary element 38 by means of a nut 44 and arranged in a groove of the fastening profile 4. The nut 44 is secured by a wedge lock washer 45 against loosening. By the securing element 40, a vertical movement of the rotary member 38 is prevented relative to the pivot bearing 36. At the same time, the rotation of the door leaf element 3d is released by the pivot bearing 36.

The securing element 40 is designed as a clamping plate, which is arranged to be inserted into a receptacle 22 of the ceiling guide 2 and the rotary member 38, in particular the cylindrical portion of the rotary member 35 surrounds. For this purpose, the clamping plate on a first recess 41, which is partially circular and smaller than the crowned portion 39 is formed so that the crowned portion 39 does not protrude through the first recess 41 ( Fig. 12 ). Thus, the clamping plate prevented by a resulting in a glass breakage fit between the clamping plate and the rotary member 38, that the rotary member 38 with the support member 43 and the associated attachment profile 4 fall down.

The securing element 40 also has a second recess 42 in order to facilitate the mounting method of the securing element 40 in the receptacle 22 of the ceiling guide 2 ( Fig. 12 ). The second recess 42 is also part-circular as the first recess 41 is formed, but has a smaller diameter as the first recess 41. The first recess 41 and the second recess 42 are connected via a slot. The receptacle 22 of the ceiling guide 2 is formed as a groove.

Furthermore, the securing element 40 is designed such that the securing element 40 has to be expanded before it is inserted into the receptacle 22. In the assembled state, a widening of the securing element 40 is prevented by the outer sides of the receptacle 22. Thus, the securing element 40 exerts pressure on the rotating element 35 and acts as a snap closure.

The insertion of the securing element 40 into the receptacle 22 is facilitated by the provision of two outwardly directed, with an angle of 20 degrees with respect to the insertion direction chamfered surfaces 96 at one of the ceiling guide 2 end facing the securing element 40 ( Fig. 12 ).

In order to effect a secure attachment of a glass pane 34 to a door leaf element 3, the glass pane 34 is positively and materially connected to the upper and the lower door rail 5 ( Fig. 13 to 15 ). For example, the glass sheet 34 may be made of high-strength composite safety glass, thereby increasing the safety level to a maximum. In addition, the laminated safety glass offers thermal protection through a low heat transfer coefficient.

Here, the glass sheet 34 on both sides of the center line M, as in Fig. 17 shown connected in two places along the width of the glass sheet 34 with the door rails 5 cohesively. In particular, the glass pane 34 is clamped in the door rail 5 and glued to the door rail 5. To produce the clamping connection between the door rail 5 and the glass pane 34 known per se glass clamps can be used. The center line M is the center axis of the door leaf element 3 in the vertical direction, which is perpendicular to the displacement direction V.

The door rail 5 has two filling openings 50, which open into two adhesive chambers 47 and serve to fill the adhesive. Alternatively, both adhesive chambers 47 can be supplied with adhesive via a single inlet opening or filling opening. In the FIGS. 13 to 15 only a portion of a door leaf element 3 is shown, wherein only one adhesive chamber 47 with the corresponding inlet opening 50 can be seen.

Between the door rail 2 and the glass plate 34, an intermediate layer 48 is inserted, wherein the intermediate layer 48 has two channel-shaped recesses 49 ( Fig. 13 and 16 ). The adhesive chambers 47 are defined by the recesses 49 of the intermediate layer 48 and the surfaces of the door rail 2 and the glass pane 34 directed towards the adhesive chambers 47. Furthermore, the adhesive chambers 47 extend parallel to the door rails 5. The adhesive chambers 47 are positioned near the vertical ends of the door leaf element 3.

The liner 48, which in Fig. 16 is shown separately, is formed in one piece and has at its distal ends in each case a punched-out for the formation of the adhesive chambers 47.

To provide a symmetric and uniform adhesive force distribution, the two adhesive chambers 47 are formed substantially identically.

Each adhesive chamber 47 preferably has a volume of between 0.5 and 30 cm ³ , more preferably between 1 and 10 cm ³ . By means of this volume, a sufficiently large adhesive reservoir is provided for a sufficiently strong adhesive bond. The adhesive chambers 47 each have a length in the direction of displacement of the door leaf element 3 from 0.05 to 0.2 times the width z of the door leaf element 3. As a result, an adhesion length and adhesive force distribution sufficient for the gluing of the glass pane 34 is provided.

Preferably, the door rail 5 comprises at least two, more preferably at least three force introduction points 89, which are formed as a screw connection and have a horizontal distance from each other. In the Figures 13 and 15 two such force introduction points 89 are shown. The clamping force, which acts on the glass pane 34 via the intermediate layer 48 via a force introduction point 89, is preferably between 2,500 and 15,000N, particularly preferably between 5,000 and 10,000N.

It is very particularly preferred for a force introduction point 89 and an adhesive chamber 47 to have a covering region, so that the force introduction point 89 is arranged in the region of the adhesive chamber 47 ( Fig. 13 ). In this way, a particularly advantageous and secure sealing of the adhesive chamber 47 can take place.

The intermediate layer 48 preferably has a strip-like design with a rectangular cross-section. As a result, in particular the realization of narrow glass clamps with a low construction height is possible. Particularly preferably, the intermediate layer 48 has a material thickness of between 0.5 and 10 mm, particularly preferably between 1 and 7.5 mm. In this material thickness, a sufficient height of the adhesive chambers 47 forms, which ensures a secure flow and distribution of an adhesive in the adhesive chambers 47. Furthermore, with these material thicknesses, a sufficiently good pressure distribution during adhesion to the glass pane 34 can be provided.

The basic shape of the adhesive chambers 47 is, as already described, preferably defined by a punched out in the intermediate layer 48. In principle, a multiplicity of basic shapes for the adhesive chambers 47 are conceivable here, such as, for example, a rectangular shape, a square shape, an ellipse shape or a circular shape.

According to the invention, the basic shape of the adhesive chambers 47 is formed rectangular symmetrical to the central longitudinal axis of the strip-like intermediate layer 48. As a result, a substantially identical sealing effect is achieved on both sides of the longitudinal extent of the adhesive chamber 47. In particular, in the form of rectangularly shaped adhesive chambers 47, the ratio of the width of the strip-like intermediate layer 48 to the width of the rectangular adhesive chamber 47 between 1.5 to 3.5 preferably between 2 to 3. This is on the one hand, a sufficient sealing effect with respect to the adhesive chambers 47 provided and on the other hand also ensures a sufficient pressure distribution in the adhesion to the glass sheet 34.

It is preferred that the intermediate layer 47 extends over 80% to 100%, particularly preferably over 85% to 95%, of the entire door leaf width of a door leaf element 3.

It is also advantageous that the door rail extends over 80% to 100%, in particular over 90% to 100% of the total door leaf width of a door leaf element 3.

The intermediate layer 48 may have a self-adhesive layer on at least one side, which allows a simple fixing of the intermediate layer 48 on the door rail 5. Furthermore, this bonding contributes to an additional sealing of the intermediate layer 48 relative to the door rail 5, in particular when the adhesive is injected into the adhesive chambers 47 defined by the intermediate layer 48. Of course, it is also possible to provide a self-adhesive layer on two sides of the intermediate layer 48.

Furthermore, it is conceivable to fix the intermediate layer 48 by a separate adhesive on the door rail 5 or to provide a self-adhesive layer, for example in the form of a double-sided adhesive tape, on the door rail 5.

In order to achieve an optimized pressure distribution and a reduction of local pressure peaks from the door rail 5 to the surface of the glass sheet 34, the intermediate layer 48 has a compressibility of 5% to 25%, particularly preferably 5% to 15%, measured according to ASTM F36 / J up.

In order to further optimize the pressure distribution, the intermediate layer 48 has a springback of 30% to 60%, preferably 40% to 50%, measured according to ASTM F36 / J.

To produce the adhesive bond, an adhesive is used whose viscosity in an uncured state, ie at the beginning of the injection process, at 20 ° C between 75,000 to 125,000 mPas, preferably between 80,000 to 110,000 mPas, measured according to DIN EN 12092.

The door rail 5 has two outlet openings 90, which serve to vent the adhesive chambers 47 and to indicate the level of the adhesive. Not shown closure elements are provided for closing the filling openings 50 and the outlet openings 90 in the sliding wall system 1.

The geometry of the adhesive chambers 47 and the filling openings 50 and the outlet openings 90 are preferably adapted to the rheological properties of the adhesive, in particular at the time of injection, so that optimum wetting of the surfaces to be bonded, complete filling of the adhesive chambers 47 and easy and safe handling of the Adhesive injection is ensured to the user within the open time of the adhesive. Open time is the maximum time within which the parts to be joined must be glued. Advantageously, an adhesive, which for the sliding wall system 1 according to the invention and the method according to the invention for fixing a glass pane 34 in a sliding wall system 1, has an open time of between 1 and 10 minutes, preferably between 2 and 5 minutes.

Furthermore, the adhesive used preferably has a tensile shear strength after about 5 to 15 minutes, preferably after about 7 to 10 minutes, of at least about 5 MPa, preferably at least about 7 MPa at 23 ° C measured according to ASTM D 1002. This ensures that a timely further processing or installation of the glued door leaf element 3 can take place.

In order to provide, in addition to the adhesion, a sufficient adhesion effect for supporting the glass pane 34 in or on the door rail 3, the adhesive in the cured state has a tensile shear strength of at least 10 MPa, more preferably at least 20 MPa, measured according to ASTM D 1002 on an aluminum substrate ,

The door rail preferably has a surface facing the adhesive chambers 47 with a surface roughness R _a of 0.5 microns to 5 microns, preferably from 1 micron to 2.5 microns, measured according to DIN EN ISO 4287, whereby an improved adhesion of the adhesive is effected on the substrate.

Each of the outlet openings 90 is arranged at the vertical end of the door leaf element 3, that is, at its vertical end face. It is thereby possible that during the injection of the adhesive, the exit of the adhesive after complete filling of the adhesive chamber on the end face of the door leaf element 3 can be observed. In particular, for ergonomic aspects of the adhesive injection process, this arrangement of the outlet opening 90 has proved to be advantageous.

The filling port 50 and the outlet port 90 for each adhesive chamber 47 are disposed at the distal ends of the channel-shaped adhesive chamber 47. As a result, in particular a complete filling of the adhesive chambers 47 is ensured with adhesive.

It is further preferred that the outlet openings 90 are formed in the intermediate layer 48, so that no throughput in the door rail 5 must be provided. Thus, the user is provided only the filling openings 50, preferably on the front side of the door rail 5. This increases the operating and mounting security of the system.

To further improve this, it can be provided that the outlet openings 90 and the filling openings 50 have mutually different cross-sectional shapes, so that a coupling with an adhesive application device is made possible exclusively via the filling openings 50.

The outlet openings 90 are each tapered with respect to the adhesive chambers 47. Advantageously, each of the outlet openings 90 is formed as a channel-shaped slot in the intermediate layer 48.

The opening width of the slot is preferably between 0.1 to 0.5, preferably between 0.15 to 0.25, with respect to the width of the basic shape of the adhesive chamber 47 defined by the punching in the intermediate layer 48. As a result, when filling the adhesive chamber 47 and when the adhesive exits, a sufficiently large hydraulic resistance opposes it, which favors complete filling of the adhesive chamber 47 and at the same time can haptically signal the user by the increased resistance even before the adhesive exits from the outlet opening 90, that the glue injection process is nearing completion.

In order to provide a sufficient reaction time for the user between the resistance increase described above and the exit of the adhesive from the outlet opening 90, the length of the channel-like outlet opening 90 has a ratio of 0.1 to 0.75 relative to the length of the channel-like adhesive chambers 47 , preferably from 0.25 to 0.5.

The fastening method of a glass pane 34 in the sliding wall system 1 according to the invention is explained below.

In a first step, a non-load-bearing connection between the door rail 5 and the glass sheet 34 by the attachment of the door rail 5 to the glass sheet 34 with a small, only the position assurance of Door rail 5 made on the glass plate 34 serving clamping force after the intermediate layer 48, in which the two recesses 49 have been punched out, between the door rail 5 and the glass plate 34 has been inserted. In a second step, a load-bearing connection between the door rail 5 and the glass pane 34 is achieved by gluing the door rail 5 to the glass pane 34.

For a better understanding of the second step of the fastening method is in the Fig. 13 to 15 an adhesive injector 51 is shown. Through the illustrated inlet opening 50, adhesive, for example a two-component adhesive, is injected into the adhesive chamber 47 by means of the adhesive injector 51. The adhesive spreads independently over the entire adhesive chamber 47. The injection of the adhesive ends when adhesive emerges from the outlet opening 90. Subsequently, the inlet opening 50 and the outlet opening 90 are closed with closure elements, not shown, and elegantly covered by panels which are attached to the door rail 5.

By gluing the glass pane 34 with the door rail 5, the functionality of the door leaf element 3 is secured for a long time. Furthermore, the simple supply of the adhesive accelerates the assembly.

Fig. 17 and 18 show a portion of the third door leaf element 3c of the sliding wall system 1 according to the present invention, wherein in the door leaf element 3c, an integrated Türbetätiger 52 is provided.

Preferably, the door operator 52 is integrated into the door rail 5 and connected via a lever arm 53 with a sliding member 54, wherein the sliding member 54 is guided in the fastening profile 4 in a guide 55. Alternatively, the door operator 52 may be arranged in the fastening profile 4 and the sliding element 54 in the door rail 5. The door leaf element 3 c is in the Fig. 17 and 18 shown in the closed state.

The guide 55, which is formed integrally with the door rail 5, is arranged on a ceiling guide 2 remote from the end of the fastening profile 4. In particular, the guide 55 is formed as a groove.

The fastening profile 4, the guide 55, the sliding member 54 and the ceiling guide 2 are arranged on the center line M. This makes a compact design possible.

How out Fig. 18 As can be seen, the door leaf element 3c has a first axis of rotation 56 about which the door rail 5 is pivotably arranged with respect to the fastening profile 4. The first axis of rotation 56 is arranged non-positively in the fastening profile 4 and in the door rail 5. In particular, the axis of rotation 56 is clamped in the fastening profile 4 and in the door rail 5. The rotation axis 56 is vertically aligned.

Fig. 19 shows a perspective view of the door leaf element 3 c, wherein the door rail 5 is shown with respect to the fastening element 4 in a pivoted position. In this case, the door operator 52 preferably has an opening angle a of 180 ° and an opening angle b of 90 ° about a zero position of the door operator 52. The zero position is understood to be the position in which the fastening profile 4, the door rail 5, the door actuator 52 and the lever arm 54 lie on the common center line M. In the zero position, the door operator 52 has an opening angle of 0 degrees and the door leaf element 3c is in the closed state. In other words, the door rail 5 of the door leaf element 3 c can be rotated by 90 degrees in both directions with respect to the fastening profile 4.

The zero position of the door operator 52 is adjustable. Preferably, the zero position can be adjusted to a opening angle of 0 degrees via a play of arranged in the door rail 5 components of the door operator 52.

In order to mount the door leaf element 3 c in the sliding wall system 1, the ceiling guide 2 is first attached to a ceiling of the building. Thereafter, the sliding member 54 is inserted into the guide 55, wherein the sliding member 54 is slidably disposed in a mounted state in the guide 55. Subsequently, the door leaf element 3 c is inserted into the ceiling guide 2. Subsequently, the door operator 52 is connected via the lever arm 53 with the sliding member 54. Alternatively, attaching the ceiling guide 2 to the ceiling and inserting the slider 54 into the guide 55 can be done in reverse order. In addition, the insertion of the sliding member 54 can be performed in the guide 55 after inserting the door leaf element 3 in the ceiling guide.

In order to be able to adapt the operation of the door leaf element 3c per application, the third door leaf element 3c, as already mentioned, has a two-sided locking mechanism 6. By the two-sided locking mechanism 6, the pivoting of the door rail 5 with respect to the fastening profile 4 and / or the displaceability of the door leaf element 3c with respect to the ceiling guide 2 can be prevented.

Fig. 20 shows an exploded view of the locking mechanism 6. The exact structure of the locking mechanism 6 is in Fig. 20 shown.

The locking mechanism 6 is provided with a locking element 57, which is arranged movably between a first position A, a second position B and a third position C on the fastening profile 4. The first position A, the second position B and the third position C are in the FIGS. 22 to 24 shown. Alternatively, the locking mechanism 6 may be movably integrated into the fastening profile 4. By the locking mechanism 6 according to the invention a lock between the mounting profile 4 and the ceiling guide 2 and / or between the mounting profile 4 and the door rail 5 is made possible. In particular, in the first position A of the locking element 57, the displaceability of the door leaf element 3 in the ceiling guide 2 is blocked. In the second position B of the locking element 57, the pivotability of the door rail 5 with respect to the fastening profile 4 is prevented. Furthermore, in the third position C of the locking element 57, the displaceability and the pivotability of the door leaf element in the ceiling guide 2 are inhibited.

Preferably, the locking element 57 is arranged rotatably about a second axis of rotation R on the fastening element 4, wherein the second axis of rotation R is perpendicular to the largest surface of the door leaf element 3c or to the center line M. Thus, the locking member 57 can be converted by rotation in the first position A, the second position B and the third position C. Particularly preferably, the locking element 57 comprises a Teilzahnradelement 59, which is directly actuated by a screw 60. Due to the self-locking of the screw 60 a secure locking is possible. Furthermore, the locking member 57 has a reinforcing portion 86, thereby providing a secure and stable lock.

The locking mechanism 6 further includes a first housing member 61, a second housing member 62, and a third housing member 63.

The first housing component 61 is connected to the ceiling guide 2 outside the ceiling guide 2. In particular, the first housing component 61 has a stop (not shown) against which the partial gearwheel element 59 and the reinforcing region 86 rest in the first position A ( Fig. 22 ). The reinforcing region 86 also has sliding properties in order to be able to slide at least on an inner surface of the first housing component 61, in particular of an inner surface extending in the direction of the width z of the door leaf element 3. Thus, the locking member 57 is guided in a manner in the first housing member 61.

The locking element 57 protrudes in the first position A via the second housing component. The formed as a Teilzahnradelement 59 locking element 57 has a radius r, so that a ratio between the radius r and a length x in the vertical direction, which extends between the rotation axis R and the first housing member 61 facing outer surface of the third housing member 63, in range from 2 to 3 ( Fig. 21 ). As a result, a stable locking in the first position A of the locking member 57 is possible.

The second housing component 62 is externally connected to the door rail 5 and has a housing groove 64, in which the locking element 57 engages in the second position B ( Fig. 23 ). In order to ensure a stable locking in the second position B, the locking element 57 has an arm region 65, which engages in the housing groove 64 of the second housing component 62. In the second position B, the arm region 65 surrounds a pin 66, which is arranged parallel to the second axis of rotation R of the locking element 57 in the second housing component 62. The locking element 57 is designed such that in the third position C, the locking element 57 engages partially in the first housing part 61 and partially in the second housing part 62 ( Fig. 24 ). The third housing component 63 is arranged on the fastening profile 4 and serves as a receptacle for the locking element 57 and the worm 60. To enable a compact construction of the third housing component 63, the axis of rotation R in the third housing component 63 is laterally in the direction of the width z of the door leaf element 3 staggered ( Fig. 21 ).

In order to change the locking state of the door leaf element 3c, the worm 60 is actuated by means of a tool. For this purpose, an access recess 83 is provided in the second housing component 62, by means of which access to the worm 60 is granted.

To indicate the locking state of the door leaf element 3c, the locking mechanism 6 is provided with a display device 58 which is partially coupled to the locking element 57. The locking mechanism 6 is based on the FIGS. 20 to 24 described.

The partial coupling of the display device 58 with the locking element 57 means that not all components of the display device 58 are connected to the locking element 57. In particular, the display device 58 has a first display element 67 and a second display element 68. The first display element 67 is rotatably arranged on the locking element 57 and the second display element 68 is rotatably coupled to the locking element 57. In addition, the first display element 67 and the second display element 68 partially overlap. This overlap results from the shape of the first display element 67 and the second display element 68. In particular, the first display element 67 is an L-shaped plate and the second display element 68 is one formed substantially rectangular plate. In order to enable a simple detection of the locking state, the first display element 67 and the second display element 68 are provided with different colors.

The display device 58 also has a first recess 69 and a second recess 70, which are arranged in the third housing component 63. By the first recess 69 and the second recess 70, a relative position between the first display element 67 and the second display element 68 is given. The first display element 67, which is generally visible through the first recess 69 and the second recess 70, can be concealed in the first recess 57 and / or in the second recess 58 by the second display element 68 depending on the locking state of the door leaf element 3c.

Thus, in the first position A of the locking element 57, which corresponds to blocking the displaceability of the door leaf element 3c in the ceiling guide 2, the first display element 67 in the first recess 69 is covered by the second display element 68 and visible in the second recess 70 (FIG. Fig. 22 ). In the second position B of the locking element 57, which corresponds to a blocking of the pivotability of the door rail 5 with respect to the fastening profile 4, the first display element 67 is concealed in the second recess 70 by the second display element 68 and visible in the first recess 69 ( Fig. 23 ). In the third position C of the locking element 57, the first display element 67 in the first recess 69 and in the second recess 70 is covered by the second display element 68 ( Fig. 24 ). This means blocking the displaceability and the pivotability of the door leaf element 3c in the ceiling guide 2.

In order to reduce drafts in a simple and reliable way or to ensure improved sealing of the sliding wall system 1 and at the same time to protect the glass edges of the glass panes 34, several seals in the form of brushes are present in the sliding wall system 1. In particular, two brushes 71 are respectively arranged on both sides of the center line M on the fastening profile 4 of a door leaf element 3 in order to seal a gap to the ceiling guide 2 ( Fig. 25 and 26 ). The brushes 71 are the first brushes 71. In addition, two first brushes 71 may be disposed respectively on both sides of the center line M on the lower door rail 5 to seal a gap to the bottom (not shown).

In Fig. 26 is a portion of the third door leaf element 3c of Fig. 1 shown. How out Fig. 26 As can be seen, two second brushes 72 are respectively disposed on either side of the center line M on a side surface of the fastening profile 4 to seal a gap to a fastening profile 4 of an adjacent door leaf element 3. Further, two further second brushes 72 are disposed on either side of the center line M on a side surface of the door rail 5 to seal a gap to a door rail 5 of an adjacent door leaf member 3. In the case of door leaf elements 3, in which no pivoting of the door rail 5 with respect to the fastening profile 4 takes place, the second brushes 72 of the same side may be integrally formed with respect to the center line M. Preferably, the first brushes 71 and the second brushes 72, which are arranged on the same side with respect to the center line M of the door leaf element 3, lie within a virtual plane E (FIG. Fig. 26 ). This means that the first brushes 71 and the second brushes 72 are arranged such that their central axes define a plane. Thus, a door seal element 3 circumferential brush seal is formed, which, for example, an improved protection against external influences is made possible. Each of the first brushes 71 is arranged displaceably in a first brush receptacle 74, the first brush receptacle 74 having a U-shaped area 75 in cross-section and being detachably arranged on the fastening profile 4. The fastening profile 4 has a channel 76, wherein the first brush holder 74 is arranged in the channel 76 by means of a frictional connection 77, in particular a splined connection.

Furthermore, the first brush holder 74 has a first receiving region 78 and a second receiving region 79, wherein the first receiving region 78 is arranged in the vertical direction above the second receiving region 79. Preferably, the first receiving area 78 and the second Receiving area 79 formed as insertion channels. Thus, the first brushes 71 can be easily mounted in the door leaf member 3 and adjusted in the vertical direction by inserting the first brushes 71 into the first receiving portion 78 or the second receiving portion 79, respectively.

Further, the second brushes 72 are slidably received in second brush receptacles 85 on the mounting profile 4 and on the door rails 5 of the door leaf element 3. Furthermore, the second brush holders 85 are arranged on both sides of the center line M. The second brush holders 85 are formed as grooves, in which the second brushes 72 are received in a form-fitting manner.

In the FIGS. 27 and 28 For example, a first brush 71 and a second brush 72 are shown.

The first brush 71 includes a first base portion 81 and a first trim 82, wherein the first trim 82 is trapezoidal in cross-section. Similarly, the second brush 72 has a second base portion 87 and a second trim 88 which is also trapezoidal in cross-section.

The first trimming 82 of the first brush 71 is made of polyamide, preferably polyamide 6.6, in particular with a fiber diameter of the first trimming 82 of 0.025 mm to 0.25 mm, very particularly preferably of 0.05 to 0.2 mm.

The second trimming 88 of the second brush 72 is made of polypropylene, in particular with a fiber diameter of the second trimming 88 of 0.01 mm to 0.2 mm, very particularly preferably of 0.025 to 0.1 mm.

The first trimming 82 may preferably have a first trimming inclination of 0 ° to 10 ° in the longitudinal direction of the first brush 71 and the second trimming 88 a second trimming inclination of 0 ° to 10 ° in the longitudinal direction of the second brush. Thus, the first brush can be better adapted to different forms of ceiling guide or temperature variations to ensure sufficient tightness. Furthermore, potential deviations in the relative position between the fastening profile and the ceiling guide and / or between adjacent door leaf elements caused by the mounting can be compensated by the inclination of the first trim and / or the second trim.

Advantageously, the first trimming 82 can have a first trimming width of 2 mm to 5 mm and a first trimming height of 1 cm to 2.5 cm, preferably of 1.5 cm to 2 cm. The second brush 72 has a second stocking width preferably between 2 mm to 10 mm, particularly preferably between 3 mm to 7.5 mm, and a second stocking height preferably between 1 cm to 2.5 cm, particularly preferably 1 cm to 1.5 cm , on.

Further preferably, the bending stiffness of the first brush 71 is greater than the bending strength of the second brush 72. The bristles or fibers, from which the trimmings 82, 88 of the brushes 71, 72 are formed, have a sufficient bending stiffness to a sufficiently good tightness the first brush 71 and the second brush 72 against mechanical or pneumatic influences, on the other hand, however, cause no damage to the surfaces of floor and / or ceiling guides when moving the door leaf elements 3 in the sliding wall system 1. This is important because in addition to sand and scratch-resistant mineral floor coverings, especially in the floor area, materials such as wood are increasingly being used whose sanding and scratch susceptibility is significantly higher.

Particularly preferably, the material of the first trimming 82 has a first bending stiffness between 0.07 Nmm ² and 0.3 Nmm ² , preferably between 0.07 Nmm ² and 0.15 Nmm ² . The material of the second trimming 88 has a second bending stiffness of 0.064 Nmm ² . The bending stiffness can be measured according to DIN EN ISO 22254.

The gap between the two adjacent door panel members 3 may vary over time due to frequent use or relative movement as well as thermal expansion or contraction. The gaps may also be different between different adjacent door leaf elements. Since the second trimming material of the second brush 72 is soft, these variations can be compensated. Variations of the gap between the mounting profile 4 and the ceiling guide 2 are usually smaller, especially when a single integral ceiling guide 2 is used for all door leaf elements, whereby a lower flexural rigidity is justified.

The first brush 71 has a first plastic film 80a and the second brush 72 a second plastic film 80b, wherein the first plastic film 80a in the first brush 71 and the second plastic film 80b in the second brush 72 is arranged centrally.

Preferably, the first plastic film 80a is made of polyethylene. In particular, polyethylene has a high toughness and elongation at break, a good sliding behavior, a low wear, a high temperature resistance and a very low water absorption.

In order to fulfill the different requirements of tightness, as already described, preferably the first plastic film 80a is single-layered and the second plastic film 80b is double-layered.

The first plastic film 80a preferably has a first film thickness between 30 .mu.m and 200 .mu.m, particularly preferably between 50 .mu.m and 150 .mu.m. The second plastic film 80b has a second film thickness between 30 .mu.m to 200 .mu.m, particularly preferably between 50 .mu.m and 150 .mu.m. The material strength of the flexibility of the first brush 71 and the second brush 72 can be controlled. The specified film thicknesses show an optimum sealing effect.

Advantageously, a first film height of the first plastic film 80a in the first brush 71 is between 100% and 150%, preferably between 105% and 125% of the first stocking height of a first stocker 82 of the first brush 71. The second plastic film 80b in the second stocker 72nd has a second film height between 100% and 150%, preferably between 105% and 125%, of the second stocking height of a second stocking 88 of the second brush 72.

In this context, it is advantageous if the first plastic film 80a in the state arranged in the first brush 71 is 2% to 20%, preferably 5% to 10%, in relation to a first brush height inwards, to the first base region 81 of the first brush 71 and the second plastic film in the state arranged in the second brush 72 are set back by 2% to 20%, preferably by 5% to 10%, in relation to a second brush height to a second base region 87 of the second brush 72. In this way, a good engagement of the second plastic films 80b of two adjacent door leaf elements 3 in the closed position and consequently an improved sealing effect is effected.

In order to ensure sufficient tightness without damaging the bottom and / or the ceiling guide 2, preferably, each of the first brushes 71 contacts the bottom and / or the surfaces with a contact pressure of 0.01 N / mm ² to 0.5 N / mm ² Ceiling guide 2.

Particularly preferably, the second stocking 88 engages in opposing second brushes 72 of two adjacent door leaf elements 3 in the closed position of the door leaf elements 3 in the sliding wall system 1. Thus it can be ensured that the adjacent door leaf elements 3 remain sealed against each other, even if the gap is interrupted by e.g. Wear of the second brush 72 becomes larger.

According to a preferred embodiment of the present invention, the second trimmings 88 of opposing second brushes 72 of two adjacent door leaf elements 3 in the closed position of the door leaf elements 3 in the sliding wall system 1 have a coverage of 2% to 20%, preferably 5% to 15% relative to the second stocking height of the second brush 72 on.

The two layers of the second plastic film 80b in the state arranged in the second brush 72 have a substantially identical second film height. This leads to a uniform load and thus to a comparable wear of the two layers.

Furthermore, the two layers of the second plastic film 80b directly adjoin one another, in particular without interposition of bristle fibers. Thus, the two layers form a unit which can better withstand mechanical or pneumatic influences and causes improved tightness.

In particular, the second plastic foils 80a of opposing second brushes 72 of two adjacent door leaf elements 3 in the closed position of the door leaf elements 3 in the sliding wall system 1 have a coverage of 1% to 20%, preferably 2% to 10%, based on the second foil height of the second brushes 72 on. By covering the second plastic films 80b in the closed position, the sealing effect can be further optimized.

Further preferably, the second brushes 72 are substantially identical to opposing second brushes 72 of two adjacent door leaf elements 3.

The sliding wall system according to the invention in particular has an air permeability based on the joint length of 5 m ³ / hm to 20 m ³ / hm, preferably 10 m ³ / hm to 20 m ³ / hm, at a differential pressure of 200 Pa, measured according to EN1026 on.
