Fig. 1 shows a perspective view of a sliding wall system 100 according to the present invention. The sliding wall system 100 according to the invention comprises a ceiling guide 200 and four door leaf elements 400a, 400, b, 400c, 400d, which are arranged next to one another in the longitudinal direction L of the sliding wall system 100 in the ceiling guide 200. The ceiling guide 200, which is designed as a one-piece running rail 300, has a length which corresponds to four times the width of the door leaf elements 400a, 400, b, 400c, 400d. Alternatively, the ceiling guide 200 can be composed of several ceiling guide elements.

The ceiling guide 200 can be attached directly to the ceiling of the building 201. The door wing elements 400 can be moved manually and / or by motor.

In particular, the sliding wall system 100 according to the invention has the Fig. 1 a first door leaf element 400a, a second door leaf element 400b, a third door leaf element 400c and a fourth door leaf element 400d, which can be equipped with certain functions. The second door leaf element 400b and the fourth door leaf element 400d are arranged pivotably, wherein the first door leaf element 400a and the third door leaf element 400c can only be moved in the ceiling guide 200. Furthermore, the second door leaf element 400b is pivotally and displaceably arranged in the ceiling guide 200. Thus, the first door leaf element 400a and the third door leaf element 400c serve as a sliding leaf, the fourth door leaf element 400d as a rotating leaf or swing leaf and the second door leaf element 400b as a rotating sliding leaf.

The gap between the door leaf elements 400a, 400b, 400c, 400d and the ceiling guide 200 or the building floor 101 can vary due to assembly tolerances and / or over time due to the frequent use or relative movement as well as thermal expansion or thermal contraction. This gap is optically and thermally sealed by means of horizontally running brushes 490a, 490b, the brushes 490a, 490b on the ceiling-side horizontal door leaf frames 410ab, 410bb, 410cb, 410db and / or the bottom-side horizontal door leaf frames 410aa, 410ba, 410ca, 410da of the door leaf elements 400a , 400b, 400c, 400d are arranged.

The brushes 490a, 490b can have a plastic film which can be arranged approximately centrally in the brush 490a, 490b.

The plastic film is preferably made of polyethylene. In particular, polyethylene has high toughness and elongation at break, good sliding behavior, low wear, high temperature resistance and very low water absorption. The plastic film can in particular also be formed in two layers.

The plastic film preferably has a film thickness between 30 μm and 200 μm, particularly preferably between 50 μm and 150 μm. The flexibility of the brushes 490a, 490b can be controlled via the material thickness. The specified film thicknesses show an optimal sealing effect.

In this context, it is advantageous if the plastic film in the state arranged in the brush 490a, 490b is set back to the base region of the brush 490a, 490b by 2% to 20%, preferably 5% to 10%, in relation to the brush height , This produces a good sealing effect with a minimized friction effect of the brushes 490a, 490b and minimized noise.

In order to ensure a sufficient tightness without damaging the floor and / or the ceiling guide 200, each of the brushes 490a, 490b preferably contacts the floor and / or with a contact pressure of 0.01 N / mm ² to 0.5 N / mm ² the ceiling guide 200.

It is further preferred that the brushes 490a, 490b in the door leaf elements 400a, 400b, 400c, 400d are essentially identical.

Out Fig. 1 it can also be seen that the horizontal sliding wall system 100 comprises a door leaf element 400a, 400b, 400c, 400d with at least two vertical door frames 440a, 440b and at least two horizontal door frames 410a, 410b, wherein a vertical door frame 440a, 440b comprises a first vertical frame profile 450a and at least one comprises second vertical frame profile 450b, and wherein a horizontal door frame 410a, 410b comprises a first horizontal frame profile 420a and at least one second horizontal frame profile (420b), and wherein all abutting edges of the ceiling guide 200, the horizontal frame profiles 420a, 420b and vertical frame profiles 450a, 450b In the assembled state of the sliding wall system 100, only form horizontal or vertical joints, which creates a particularly harmonious and aesthetic appearance of the sliding wall system 100.

Fig. 2 shows a cross section through the ceiling guide 200 from Fig. 1 known sliding wall system 100. The ceiling guide 200 is fixed to the building ceiling 201. The ceiling guide 200 comprises a running rail 300 in which a roller carriage 500 is slidably arranged. A door leaf element 400 is arranged in a hanging manner on the roller carriage 500.

The running rail 300 is essentially U-shaped, the free legs of the U-shaped running rail 300 forming the end faces 301a, 301b of the running rail 300. Furthermore, in particular at the distal end of the free legs of the U-shaped running rail 300, running surfaces 302a, 302b are formed for guiding the roller carriage 500.

The running rail 300 is formed from a first material with a thermal conductivity of 75-235 W m ^-1 K ^-1 and a thermal coefficient of linear expansion of 21-24 ^∗ 10 ^-6 K ^-1 .

Both end faces 301a, 301b of the running rail 300 preferably have a surface roughness parallel to the extrusion direction of Ra 0.1-3, preferably of Ra 0.2-2, particularly preferably of Ra 0.75-1.8 measured according to DIN EN ISO 4287 , This makes it possible to achieve particularly advantageous adhesive and contact properties for the thermal separation profile to be fastened to the running rail, which will be explained in more detail below.

The thermal separation profile 320 is arranged on an end face 301b of the running rail 300 via a fastening means 325, in particular a screw, clamp or adhesive connection. Although in Fig. 2 If only one thermal separation profile 320 is arranged on one of the end faces 301b, it is of course possible and advantageous to provide a thermal separation profile on both end faces 301a, 301b.

The thermal separation profile 320 bears against the end face 301b of the running rail 300. For installation, the thermal separation profile 320 comprises a plurality of mutually separated contact surfaces 321a, 321b, 321c, 321d between the thermal separation profile 320 and the end face 301b of the running rail 300. In order to further improve the thermal separation, it is preferred that the entire contact surfaces 321a , 321b, 321c, 321d of the thermal separation profile 320 correspond to between 1-10% of the area of an end face 301b of the running rail 300.

On the side 301b facing the running rail 300, the thermal separation profile 320 has at least one open channel-like depression 322a, 322b, 322c, as a result of which the structural stability of the thermal separation profile 320 and also its thermal separation properties can be further improved. In the exemplary embodiment shown, a first channel-like depression 322a, a second channel-like depression 322b and a third channel-like depression 322c are formed.

In order to fix a running rail cover 350, the thermal separating profile 320 has at least one connecting means 323a, 323b, preferably at least two connecting means 323a, 323b for receiving a running rail cover 350 with corresponding connecting means 351a, 351b for releasably connecting the thermal separating profile 320 to the running rail cover 350.

The thermal separation profile 320 also has a contact leg 324, which bears against the outer horizontal running rail section 303 of the running rail 300. By contacting a horizontal surface of the running rail 300, the contact leg 324 ensures a defined positioning of the thermal separation profile 320 on the running rail 300.

A groove-like guide 326 for receiving the free bristle ends of a brush 490a can be provided on the contact leg 324. The guide 326 is shaped such that the free bristle ends of the brush 490a arranged below the running rail 300 in the horizontal door leaf frame 410 are at least partially enclosed by the groove-like guide 326. On the one hand, this results in an optically appealing joint pattern of the sliding wall system 100, since fraying of the bristle ends of the brush 490a, which usually occurs when sliding wall systems are in operation, is visually covered by the groove-like guide 326. Furthermore, the groove-like guide 326 improves the windproofness of the sliding wall system, since by fixing the free end of the bristles of the brush 490a, this has improved mechanical stability.

The thermal separation profile 320 is formed from a second material with a thermal conductivity of 0.02-0.1 W m ^-1 K ^-1 and a thermal coefficient of linear expansion of 40-300 ^∗ 10 ^-6 K ^-1 .

The thermal separation profile 320 is in particular formed in one piece. The thermal separation profile 320 preferably extends over 50-100%, preferably 75-100%, particularly preferably 90-100% of the length L _{LS of} the running rail 300. Furthermore, it is preferred that the thermal separation profile 320 extends over 50-100%, preferably 75-100%, particularly preferably 90-100% of the height H _{LS of} the running rail.

The running track cover 350 is detachably fixed to the thermal separating profile 320 via the connecting means 351a, 351b which, with the corresponding connecting means 323a, 323 of the thermal separating profile 320, produce a non-positive and / or positive connection.

The track cover 350 is essentially L-shaped and has a groove 352 on its ceiling-side distal end for receiving a sealant 350-01 for sealing the track cover 350 against the ceiling structure 201 of a building.

The track cover 350 is formed from a third material with a thermal conductivity of 75-235 W m ^-1 K ^-1 and a thermal coefficient of linear expansion of 21-24 ^∗ 10 ^-6 K ^-1 .

Out Fig. 2 it can also be seen that the door leaf element 400 comprises a horizontal frame profile 420, in which a brush 490 for sealing the horizontal gap between the door leaf element 400 and the running rail 300 is accommodated, with means for vertical adjustment of the brush 490a in the frame profile 420 within the horizontal frame profile 420 are provided. These means for vertical adjustment of the brush 490 in the horizontal frame profile (420) comprise according to the in Fig. 2 In the exemplary embodiment shown, a brush profile 491, in which the brush 490 is received, and an essentially U-shaped receptacle 432 in the horizontal frame profile 420, in which the brush profile 491 is accommodated so that it can be adjusted and / or locked in the vertical direction. The brush profile 491 has a first latching means 492 which interacts with the corresponding second latching means 433 of the U-shaped receptacle 432 in such a way that an adjustable latching of the brush profile 491 in the receptacle 432 is brought about. For this purpose, at least one spring element 493a, 493b is arranged on the brush profile 491, which is supported in the receptacle 432 in order to generate a spring force such that the brush profile 491 is fixed in the receptacle 432. A spring element 493a, 493b can in particular be formed in one piece with the brush profile 491.

Fig. 2 shows a roller carriage 500 within the ceiling guide 200 of the sliding wall system 100 according to the present invention. The roller carriage 500 is connected to a door leaf element 400 by means of a connecting element in the form of a block 436, which is inserted into the ceiling-side horizontal door leaf frame 410 and is supported against the shoulder 434. As a result, the door leaf element 400 is displaceably arranged in the ceiling guide 200, which is formed from running rail rails 300 and optionally switches (not shown). A plurality of roller carriages 500 are provided in the sliding wall system 100. All door leaf elements 400a, 400b, 400c, 400d preferably have identical roller carriages 500. A door leaf element 400a, 400b, 400c, 400d is preferably guided in the running rail 300 by at least two, preferably exactly two, roller carriages 500.

The roller carriage 500 from Fig. 2 has a base body 524, on which a plurality of rollers 525a, 525b, 525c, 525d and a plurality of guide rollers 526a, 526b are arranged. How from Fig. 2 As can be seen, the roller carriage 500 comprises four rollers 525a, 525b, 525c, 525d and four guide rollers 526a, 526, b, 526c, 526d (the guide rollers 526c, 526c being covered by the guide rollers 526a, 526b), the rollers 525a, 525b , 525c, 525d are arranged perpendicular to the guide rollers 526a, 526, b, 526c, 526d. A fail-safe displacement and guidance of the door leaf element 400 in the ceiling guide 200 can thus be ensured.

The rollers 525a, 525b, 525c, 525d, which are of identical design, each have a roller body 527 with a roller surface 528, the roller bodies 527 rolling on two running surfaces 302a, 302b of the running rail 300.

The base body 524 has a modulus of elasticity at 20 ° C of 70 kN / mm2 to 100 kN / mm2, preferably approx. 85 kN / mm2, according to EN ISO 6892-1: 2009, a shear modulus at 20 ° C of 20 kN / mm2 to 60 kN / mm2, preferably approx. 40 kN / mm2 according to DIN 53445, and a density at 20 ° C of 2 g / cm3 to 7 g / cm3, preferably approx. 6.7 g / cm3, according to ISO 527-1 / -2, on.

The roller body 527 has a modulus of elasticity at 20 ° C of 2 kN / mm2 to 4 kN / mm2, preferably approx. 3 kN / mm2, according to ISO 527-1 / -2, a shear modulus at 20 ° C of 0.5 kN / mm2 to 1 kN / mm2, preferably approx. 0.8 kN / mm2, according to DIN ISO 1827: 2010-07 and a density at 20 ° C of 1g / cm3 to 2 g / cm3, preferably approx. 1.4 g / cm3, according to DIN EN ISO 1183. Furthermore, the roller surface 528 of the roller body 527 has a surface roughness Ra of 0.01 to 3 µm, preferably 0.05 µm to 2 µm according to DIN EN ISO 4287.

The roller body 527 preferably also has a diameter of 16 mm to 20 mm, particularly preferably of 18.5 mm. The roller surface 28 of the roller body 27 preferably has a roller surface width of 5 mm to 9 mm, preferably 7 mm.

The roller body 527 also has a water absorption of 0.3% in a normal climate according to ISO 62. Water absorption in a normal climate describes the percentage weight gain of a body due to water absorption when stored at a temperature of 23 ° C and humidity of 50%. According to the invention, the water absorption of the roller body is kept low in a normal climate. A high water absorption leads to a high flattening of the roller body 527, which causes noise when the roller body 527 of the roller 525 rolls on the running surface 529 of the ceiling guide 200.

The roller body 527 also has a water absorption of 1.4% when water is stored according to ISO 62. Water absorption during water storage refers to the percentage weight gain of a body due to water absorption when stored in water. The roller body 527 of a roller 525 is designed such that its water absorption is kept low when water is stored. Flattening of the roller bodies 527, e.g. in a sliding wall system 100, which is arranged in an outside space. This ensures quieter operation under different weather conditions.

Furthermore, the roller body 527 has a flattening of less than 0.7% in relation to the diameter of the roller body 527 after the roller body 527 has been idle for 8 hours. The low permissible flattening of the roller bodies 527 significantly increases the smooth running of the sliding wall system 100 according to the invention. The flattening of a roller body 527 is measured by applying a test load of 200 N in the vertical direction to the roller body 527 arranged on a support. The roller body 527 with a diameter of 18.5 mm particularly preferably has a maximum flattening of 0.12 mm after 8 hours of standstill.

The running surfaces 529 of the ceiling guide 200 each have a modulus of elasticity at 20 ° C of 60 kN / mm2 to 80 kN / mm2, preferably approx. 70 kN / mm2, according to EN ISO 6892-1: 2009, a shear modulus at 20 ° C of 10 up to 40 kN / mm2, preferably approx. 27 kN / mm2, according to DIN 53445 and a density at 20 ° C of 2 to 5 g / cm3, preferably approx. 3 g / cm3, according to ISO 527-1 / -2. Furthermore, the running surfaces 529 have a surface roughness Ra of 0.05 to 1.0 μm, preferably approximately 0.5 μm, measured in accordance with DIN EN ISO 4287.

The running surfaces 302 each have inner surface grooves substantially parallel to the direction of displacement V of the door leaf element 400. Internal surface creasing is to be understood as an essentially linear surface structure consisting of a plurality of parallel linear depressions on the running surface 302, which is produced by the extrusion process. Furthermore, the running surfaces 302 of the ceiling guide 200 are formed in one piece with the ceiling guide 200. A compact structure is thus possible. Furthermore, potential assembly errors, such as, for example, misalignment, are eliminated, as a result of which noises occur when the door leaf elements 400 roll in the ceiling guide 200 could be caused. The ceiling guide 200 has a density of 2 to 5 g / cm3, preferably approximately 3 g / cm3, according to ISO 527-1 / -2. The running surfaces 302 of the ceiling guide 200 each have a running surface width which is greater than the roller surface width of the roller surfaces 528 of the roller bodies 527.

Each of the roller bodies 527 is mounted on the roller carriage 500 in particular by means of a closed ball bearing. The roller body 527 has an axis with two knurls, by means of which the roller body 527 is attached to the base body 524 of the roller carriage 500 in a rotationally fixed manner. The axle also serves as the inner ring of the ball bearing. The ball bearing has seven balls, which are greased with lithium soap grease.

Furthermore, the static surface pressure between a roller 527 and the running surface 529 of the ceiling guide 200 is at least 2.5 kg / mm 2, preferably between 2.5 and 100 kg / mm 2. This leads to the elimination of squeaking noises when moving the door leaf elements 400.

The average travel speed of the roller carriage 500 is between 0.05 and 0.5 m / s, preferably approximately 0.2 m / s.

Furthermore, the pushing torque of a door leaf element 400, which is arranged displaceably in the ceiling guide 20, is, for example, the door leaf element 400a, 400b and / or 400c from Fig. 1 , 8N to 15 N, preferably 10N to 14N, particularly preferably 11N to 13 N with a weight of the door leaf element 400a, 400b and / or 400c of 175kg. After 100,000 cycles, the pushing torque of the door leaf element 400a, 400b and / or 400c is still 15N to 21N, preferably 16N to 20N, particularly preferably 17N to 19N.

The roller carriage 500 according to the invention and the treads 529 according to the invention of the ceiling guide 200 enable a quiet movement of the sliding wall system 100. The abrasion of the roller bodies 527 is reduced and the service life of the roller carriage 500 is thus significantly increased. In addition, squeaking of the rollers 525 can be eliminated.

Fig. 3 shows a vertical door frame 440 of a door leaf element 400 of the sliding wall system 100 according to the invention.

The door leaf element 400 comprises at least two vertical door frames 440a, 440b. The vertical door frames 440a, 440b are preferably essentially geometrically, in particular also essentially identical in material.
