Description

DESCRIPTION

Sliding partition system with improved acoustic behavior

The invention relates to a sliding partition system with at least one door wing element that has improved acoustic behavior when moving.

Sliding partition systems and their door swing elements are known, for example, in the case of multi-swing entry doors, in the case of partition sliding elements used as space dividers or in the case of wall elements in Front areas of buildings, particularly in restaurants and shops, to keep the premises accessible or closed depending on the weather. The door swing elements are, as a rule, movably accommodated in ceiling guides mounted on the ceiling side. In this regard, the individual swing elements can be parked in a lateral position, so that no impediment to the transit of entering public takes place.

Generic type sliding partition systems are known, for example, from EP1403459A2 and GB918797A.

Sliding partition systems can present, in particular, comparatively high noise emissions compared to revolving or swinging doors, which usually result from rolling noise and structural noise transmission resulting from the mobile elements of sliding partition systems of this type. A certain squeaking is also known in the displacement of the door swing elements of sliding partition systems, which are regularly perceived by users as extremely annoying.

However, in sliding partition systems of this type, on the one hand, the smooth running of a door hinged element usually held and guided by a roller carriage by users can always be assessed by a quality indication, which can be perceived by the user directly and immediately for a sliding partition system.

On the other hand, particularly in situations of buildings sensitive to noise emissions, such as bedrooms and rest rooms, accesses to offices, concert buildings, conference spaces, spas or wellness spaces in hotel facilities, the use of Noisy sliding partition systems are currently only possible to a limited extent.

Therefore the objective of the present invention is to provide a sliding partition system with great running smoothness, in particular without squeaks.

The object according to the invention is solved by a sliding partition system according to claim 1, comprising: at least one ceiling guide, at least one door leaf element, which is fastened on at least one roller carriage and is arranged so that it can slide on the ceiling guide, where the at least one roller carriage has a base body, on which at least one running roller and / or at least one guide roller are arranged, where the roller The running gear and / or the guide roller have a roller body, and wherein the roller carriage is displaceably arranged by the roller body that rolls on at least one running surface of the ceiling guide in the guide of the ceiling. According to the invention, the base body has a modulus of elasticity at 20 ° C of 70 kN / mm2 to 100 kN / mm2, preferably approximately 85 kN / mm2, measured according to EN ISO 6892-1: 2009, a modulus of shear at 20 ° C from 20 kN / mm2 to 60 kN / mm2, preferably approximately 40 kN / mm2, measured according to DIN 53445, and a density at 20 ° C of 2 g / cm3 to 7 g / cm3, preferably about 6.7 g / cm3, measured according to ISO 1183. The roll body has, according to the invention, a modulus of elasticity at 20 ° C of 2 kN / mm2 to 4 kN / mm2, preferably about 3 kN / mm2, measured according to ISO 527-1 / -2, a shear modulus at 20 ° C from 0.5 kN / mm2 to 1 kN / mm2, preferably approximately 0.8 kN / mm2, measured according to DIN ISO 1827: 2010-07, and a density at 20 ° C of 1 g / cm3 to 2 g / cm3, preferably approximately 1.4 g / cm3, measured according to ISO 1183. According to the invention, the running surface has a modulus of elasticity at 20 ° C from 60 kN / mm2 to 80 kN / mm2, preferably approximately 70 kN / mm2, measured according to EN ISO 6892-1: 2009, a shear modulus at 20 ° C of 10 kN / mm2 at 40 kN / mm2, preferably approximately 27 kN / mm2, measured according to DIN 53445, and a density at 20 ° C of 2 g / cm3 to 5 g / cm3, preferably approximately 3 g / cm3, measured according to ISO 1183 standard, where the running surface at least by sections presents a groove essentially parallel to a direction of movement of the door swing element. A groove is an essentially linear surface structure from a large number of linear depressions arranged in parallel. By means of the sliding partition system according to the invention the smooth running of the sliding partition system can be increased and a squeal in the movement of door swing elements can be reduced or eliminated. This is achieved because the cooperative construction elements of the sliding partition system, in particular the roller body of the running roller and the running surface of the roof guide, are neither too smooth nor too rough. According to the invention, a balance is reached between an intersection point that is too smooth and one that is too rough between construction elements that move towards each other. A setup too smooth produces squeaking noises. On the other hand, a configuration that is too rough causes high wear which, on the one hand, results in deterioration of the roller body or of the running surface and, on the other hand, causes additional noises through the generation of particles.

According to the invention, the groove of the running surface has a surface roughness Ra of 0.05 | jm to 1.0 jm, preferably approximately 0.5 jm, measured according to DIN EN ISO 4287. Consequently, a rolling of the door swing element in the ceiling guide with even less noise. The roller body is housed by a closed ball bearing on the roller carriage. Ball bearings provide very good rolling properties and low noise operation as the internal space of the ball bearing is protected from particles and impurities.

According to the invention, a roll surface of the roll body has a surface roughness Ra of 0.01 to 3 jm, preferably 0.05 to 2 jm. Consequently, wear on the roller surface of the roller body and of the running surface of the roof guide is reduced, thereby preventing the generation of material particles that remain on the running surface and cause abrasion and high emissions. of noise. The surface roughness is measured according to DIN EN ISO 4287.

Especially preferably the groove of the running surface and the roll surface of the roll body have the same surface roughness. Therefore, reduced abrasive wear is made possible, which leads to the generation of material particles being eliminated. Consequently a higher running smoothness of the sliding partition system is guaranteed.

Advantageously, the running surface of the roof guide is configured from an extruded material. This has the consequence that the running surface has good surface properties, in particular it is manufactured in the least ribbed way possible without the need for subsequent finishing steps. This ensures a low noise running of the door swing element in the ceiling guide. Furthermore, extrusion offers the advantage that profiles can also be manufactured in an affordable way in more complicated shapes and from materials of complicated shaping. Furthermore, in a process step, a high degree of conformation can be achieved.

Otherwise it is advantageous when the running surface of the roof guide is configured in one piece with the ceiling guide. Therefore a compact structure is possible. In addition, potential mounting errors such as tilting are eliminated, whereby rolling noise of the door swing element in the ceiling guide could be caused.

Furthermore preferably the running surface of the ceiling guide is configured larger than the roller surface. As a result, mounting deviations are compensated for, so that the door swing element is moved with little noise.

According to the invention, the static surface pressure between the running roller and the running surface of the roof guide is at least 2.5 kg / mm2, preferably between 2.5 and 100 kg / mm2. This produces a squeaky noise elimination in the movement of the door swing element.

In order to securely hold the roller body in the base body of the roller carriage resistant to torsion, the roller body can preferably have a shaft with at least one knurling. Therefore, the probability of loosening of the roller body is clearly reduced, which could lead to loud noises.

To optimize the low-noise operation of the sliding partition system the roller body shaft can be configured with a one-piece closed inner ball bearing ring. In this way an additional shaft is dispensed with, thus avoiding potential mounting errors. Consequently noise can be reduced.

Advantageously, the sliding partition system according to the invention can have a glass panel with a memory foam sheet, where the sheet has a soundproofing function. The noises that are formed in the rolling of the door swing element in the ceiling guide are at least partially muffled by the leaf and therefore are not perceived by the user.

Furthermore preferably the roll body has a water absorption of 0.3% in normal weather. Absorption of water in normal weather designates the percentage increase in weight of a body by absorption of water in the case of storage at a temperature of 23 ° C and humidity of 50%. Preferably the water absorption of the roller body in normal weather is kept low. High water absorption causes high flattening of the roll body, whereby rolling noises of the roll body of the rolling roll are caused on the running surface of the roof guide. Water absorption in normal weather is measured according to ISO 62.

In addition, preferably, the roller body has a water absorption of 1.4% in the event of storage in water. Absorption of water in case of storage in water designates the percentage increase in weight of a body by absorption of water in case of storage in water. The roller body of the running roller is configured such that its water absorption in case of storage in water is kept low. Consequently a flattening of the roller body is reduced, for example in the case of a sliding partition system, which is arranged in an external space. Therefore, operation with less noise in different weather conditions can be guaranteed. The absorption of water in case of storage in water is measured according to ISO 62.

Especially preferably the roller body has a flattening of less than 0.7% with respect to the diameter of the roller body after 8 hours of rest of the roller body. The reduced permitted flattening of the roller body significantly increases the smooth running of the sliding partition system. The flattening of a roller body27 is measured, by exerting a test load of 200 N in the vertical direction on the roller body 27 arranged on a support.

Especially preferably, the average travel speed of the roller carriage is between 0.05 m / s and 0.5 m / s, preferably about 0.2 m / s. This travel speed offers, on the one hand, the advantage of rapid rolling of the roller body on the running surface. On the other hand, the smooth running of the sliding partition system is maintained.

The invention is now described in more detail taking into account the attached drawing. Shows:

Figure 1 shows a perspective view of a sliding partition system 1 according to an embodiment of the present invention. The sliding partition system 1 comprises a ceiling guide 2 and four door wing elements 3, which in the longitudinal direction L of the sliding partition system 1 are arranged next to each other on the ceiling guide 2. All door swing elements 3 have the same width z. The ceiling guide 2, which is configured as a single-piece rail 10, has a length that corresponds to four times the width z of the door wing elements 3. As an alternative, the ceiling guide 2 can be composed of several elements of ceiling guide.

Furthermore, the sliding partition system 1 is arranged in a frame 9. In particular the ceiling guide 2 is provided in an upper part of the frame 9 that is fastened to a roof of a building not shown. As an alternative, the roof guide 2 can be attached directly to a roof of the building. A lower part of the frame 9 is firmly attached to a building floor also not shown.

In particular, the sliding partition system 1 of FIG. 1 has a first door swing element 3a, a second door swing element 3b, a third door swing element 3c and a fourth door swing element 3d which they may be equipped with specific functions. The first door swing element 3a as well as the fourth door swing element 3d are pivotally arranged on the ceiling guide 2 and rotatably mounted on the floor, where the second door swing element 3b can only sliding on the ceiling guide 2. Furthermore, the third door swing element 3c is pivotally and slidingly arranged on the ceiling guide 2. Thus, the first door swing element 3a and the fourth door swing element 3d serve as a rotary swing or swing leaf, the second door swing element 3b as a sliding swing and the third door swing element 3c as a swing rotating slider.

All the door swing elements 3 each have a clamping profile 4, two door rails 5 and a glass panel 34 that are arranged between the door rails 5. The clamping profiles 4, the door rails 5 and glass panels 34 are configured identical on all door swing elements 3. The door track 5 of each door leaf element of the door leaf elements 3a, 3b, 3c and 3d is arranged at one end directed to ceiling guide 2 and the other at one end directed to the ground.

Otherwise the sliding partition system 1 comprises three locking mechanisms.

The third door swing element 3c has an interlocking mechanism 6 which is a two-sided interlocking mechanism. Thus, twisting of the door rails 5 and the glass panel 34 of the third door swing element 3c, which are firmly connected to each other, with respect to the clamping profile 4 of the third door swing element 3c can be prevented. Furthermore, by means of the two-sided locking mechanism 6, a movement of the third door leaf element 3c in the ceiling guide 2 in a movement direction V can be blocked. The movement direction V is determined by the shape of the ceiling guide. 2. In this sense the displacement direction V corresponds to the displacement direction L of the sliding partition system 1. The structure and function of the two-sided locking mechanism 6 are described below with respect to FIGS. 2 to 24.

A three-sided locking mechanism 8 is provided in all the door leaf elements 3, which causes the locking in three directions. The three-sided locking mechanism 8 enables a door wing element 3 to be locked into an adjacent door leaf element 3, the frame 9 or the floor, and has an additional closing function.

An interlocking mechanism 7 is arranged on the first door swing element 3a on the one hand that prevents twisting of the first door swing element 3a with respect to the ceiling guide 2.

However, since the interlocking mechanism 7 on the one hand as well as the interlocking mechanism 8 on the three sides are not part of the object of the present invention they are not explained in more detail herein.

Figures 2 and 3 show a partial area of a ceiling guide 2 of a sliding partition system 1. As can be seen from these figures, the ceiling guide 2 is made up of three rails 10, in particular a first rail 10a, a second rail 10b and a third rail 10c, and by a deflection device 11, which is configured as a detour 15.

Turnout 15 has three connecting surfaces to which the three rails 10a, 10b and 10c are connected. The rails 10a, 10b and 10c are connected to the diversion 15 by a large number of connection kits 18. Each connection kit 18 has an insert 19 which is inserted in a slot 20 of one of the rails 10 and in a slot 21 of the deflection device 11, and is screwed into the rails 10, as well as the deflection 15. In particular in figure 2 a first connection kit 18a, a second connection kit 18b and a third connection kit 18c are shown . The first rail 10a is connected to the deflection device 11 by means of the first connection device 18a, which has a first insertion element 19a, a first groove 20a configured in the first rail 10a and a first groove 21a configured in the deflection device. 11. The second joining equipment 18b has a second insertion element 19b, a second slot 20b configured in the second rail 10a and a second slot 21b configured in the deflection device 11 and joins the second rail 10b with the deflection device 11 Through the third joining equipment 18c, which consists of a third insertion element 19c, a third slot 20c configured in the third rail 10c and the second slot 21b of the deflection device, the third rail 10c is connected to the deviation 10. In Figures 2 and 3 a roller carriage 23 is further drawn on the ceiling guide 2 which is described in more detail with respect to Figures 7 to 10.

Figures 4 and 5a show perspective views of the diversion 15. To facilitate a diversion of the roller carriage 23 in the ceiling guide 2, the diversion 15 has a deflector element 16. The deflector element 16 is arranged on an internal side 17 of the detour 15 directed to the roof of the building. In particular, the deflector element 16 is screwed into the diversion 15 by means of steel screws (figure 4). Furthermore, the deflector element 16 is made of plastic, in particular polyoxymethylene. The rails 10 each have a first slit 12. The diversion 15 has two second slits 13 that communicate with each other. In the assembled state of the roof guide 2 the first grooves 12 of the rails 10a, 10b and 10c join the second grooves 13 of the turnout 15 and form a continuous groove course (Figure 3).

Figure 6 shows a deflection device 11 in the form of an arc 14. Arches are used in sliding partitions when a direction of movement of a door leaf element must be changed by approximately 90 degrees. This may be the case, for example, when the door swing element must be moved to a parking position of the sliding partition system.

The arch 14 has two connection surfaces to which two rails 10a and 10b can be joined, where the arch 14 is configured with a quarter circle groove 13.

Deviation 15 and arch 14 are configured in the basic form as U profiles.

The rails 10 and the deflection devices 11, of which the ceiling guide 2 is composed, are manufactured by means of an extrusion process. In particular the rails 10 and the deflection devices 11 are extruded from the same material. The deflection devices 11 are each configured from an essentially rectangular or square extruded body in cross section. The rails 10 and the deflection devices 11 have adjacent visible surfaces with essentially the same extrusion direction. Consequently a very similar or equal optical impression is achieved on these visible surfaces.

A first visible surface 91, a second visible surface 92 and a third visible surface 93 of the turnout 15 are shown in FIG. 3, as well as a first visible surface 94 and a second visible surface 95 on each of the rails 10. The rails 10 and deflection device 11 have additional visible surfaces which are not however visible in figure 3. The number of visible surfaces depends on the shape of a rail or deflection device and their arrangement in a sliding partition system .

The deflection devices 11 are machined by chip removal from extruded bodies, where the visible surfaces of the deflection device 11 adjoining the rails 10 are not machined by chip removal.

To further enhance the overall appearance of the ceiling guide 2 all visible surfaces of the rails 10 are not machined by chip removal. For this reason, the ceiling guide 2 generates a uniform and harmonious aesthetic appearance.

The rails 10 each have a first external surface groove and the deflection device 11 a second external surface groove on their visible surfaces abutting each other in the extrusion direction, which has a groove direction essentially parallel to the direction of travel. V of a door wing element 3. An externally linear groove or groove is to be understood as meaning an essentially linear surface structure from a large number of parallel-arranged linear depressions, which are generated by the extrusion process and influence the surface quality as well as the optical impression of a surface.

Preferably, the groove of the adjacent visible surfaces has a roughness Ra of 0.1 pm at 2.0 | jm, preferably from 0.2 | jm to 1.6 | jm, very particularly preferably from 0.2 | jm to 1 | jm, measured according to DIN EN ISO 4287 in a transverse direction to the groove orientation.

In a preferred embodiment, all the visible surfaces of the deflection device 11 and the rails 10 have a roughness Ra of 0.1 jim to 2.0 jim, preferably 0.2 jim to 1.6 jim, very especially preferably 0.2 jim to 1 jim, measured according to DIN EN ISO 4287 in the transverse direction to the groove orientation.

According to a highly preferred embodiment, the deviation in the roughness of visible surfaces adjoining each other of the deviation device 11 and the rails 10, preferably of all visible surfaces, amounts to in a range Ra of 0.1 jim to 2 0.01 jim, preferably 0.2 jim to 1.6 jim, most especially preferably 0.2 jim to 1 jim, <10%, preferably <5%.

Additionally, it is highly preferable that visible surfaces of the rails 10 and of the deflection device 11 adjoining each other, preferably all the visible surfaces, present an essentially identical roughness in the transverse direction to the groove orientation.

The optical impression can be further improved when the adjacent visible surfaces of the deflection device 11 and the rails 10 have a surface roughness Ra parallel to the extrusion direction of 0.1 jim to 3 jim, preferably 0.2 jim to 2 jim, particularly preferably from 0.75 jim to 1.8 jim, measured according to Din En ISO 4287.

It is especially highly preferable that all the visible surfaces of the deflection device 11 and the rails 10 have a surface roughness Ra parallel to the extrusion direction of 0.1 jim to 3 jim, preferably 0.2 to 2 jim, in particular preferably from 0.75 jim to 1.8 jim, measured according to DIN ^e N ISO 4287.

In a highly preferred configuration it is further preferred preferably that the deviation of the surface roughness Ra parallel to the extrusion direction of at least two visible surfaces abutting each other of the rails 10 and of the deviation device 11, preferably of all surfaces visible, selected from the Ra range of 0.1 jim to 3 jim, preferably 0.2 jim to 2 jim, amount to <10%, in particular <5%.

In a further highly advantageous further development of the invention the surface roughness Ra parallel to the extrusion direction of at least two visible surfaces abutting the rails 10 and the deflection device 11, preferably all visible surfaces, is essentially identical.

Furthermore, for the further improvement of the optical impression, it is advantageous that at least the visible surfaces of the deflection device 11 and the adjacent rails 10 have a degree of brightness of 1 GE to 50 GE, preferably from 5 GE to 25 GE, measured at a 60 ° angle according to DIN 53778.

It is especially highly preferable that all visible surfaces of the deflection device and the rails have a degree of gloss from 1 GE to 50 GE, preferably from 5 GE to 25 GE, measured at an angle of 60 ° according to DIN 53778 .

In a highly preferred embodiment the deviation from the degrees of gloss selected from the range of 1 GE to 50 GE, preferably from 5 GE to 25 GE, from the adjacent visible surfaces amounts to <10%, particularly preferably <5 %.

According to a further preferred configuration the adjacent visible surfaces have an essentially identical degree of gloss selected from the range of 1 GE to 50 GE, preferably from 5 GE to 25 GE. As can be seen from figure 5b, the deflection device 11 is configured as a hexagonal body. The hexagon of the body results in the plan view of the deviation device 11 of a hexagonal base surface, where from the at least three of the six sides of the base surface side walls of the same height descend in perpendicular, which define the height deviation device 11.

A first side and a second side facing the first side have essentially the same first length l1 and the remaining four sides of the hexagon have the same second length l2 where the first length l1 is greater than the second length l2.

In order to provide a visible surface of the deflection device 11 as visually adapted as possible, one visible surface has the first length l1 and two additional visible surfaces the second length l2. The visible surface of the first length l1 has the same extrusion direction as the visible surfaces of the rails 10 in contact with this surface.

To facilitate a hexagonal shape that can be further machined by chip removal from the extruded body in the most favorable way possible to form the deflection device 11, two adjacent sides of the second length 12 are perpendicular to each other.

In order to configure the entire sliding partition system 1 in optical harmony, the door rails 5 of the door swing elements 3 are also extruded and have at least one visible surface and have essentially the same extrusion direction as the neighboring adjacent visible surfaces. of the rails 10 and the deflection device 11.

In order to manufacture the sliding partition system 1 with the ceiling guide 2, a body for the rails 10 and a body for the deflection device 11 are extruded in each case in discretionary order. Rails 10 and deflection device 11 are extruded from the same material.

The extruded body for the deflection device 11 is then machined by chip removal.

The rails 10 and the deflection device 11 are assembled to configure the ceiling guide 2 so that the rails 10 and the deflection device 11 have visible surfaces adjoining each other and the visible surfaces adjoining each other of the rails 10 and the device deflection 11 have essentially the same extrusion direction. Next, a door swing element 3 is placed in the ceiling guide 2 of the sliding partition system 1. Consequently, deviations in the optical impression of the rails 10 and of the deviation devices 11 can be eliminated.

Figure 7 shows a roller carriage 23 inside the ceiling guide 2 of the sliding partition system 1 of an embodiment according to the present invention. The roller carriage 23 is connected by means of a connecting element in the form of a block 30 with a door wing element 3, such as, for example, the second door leaf element 3b of the sliding partition system 1 of FIG. 1. The door swing element 3b in the ceiling guide 2, which is configured of rails 10 and deflection devices 11, is thus displaceably. A large number of roller carriages 23 are provided in the sliding partition system 1.

The roller carriage 23 of FIG. 7 has a base body 24, on which a large number of running rollers 25 and a large number of guide rollers 26 are arranged. As can be seen from FIG. 8, the roller carriage 23 comprises four running rollers 25 and four guide rollers 26, wherein the running rollers 25 are arranged perpendicular to the guide rollers 26. Accordingly, movement and guidance of the door swing element 3b in the guide can be guaranteed 2 failsafe ceiling.

The running rollers 25, which are identical in each case, have a rolling body 27 with a rolling surface 28, where the rolling bodies 27 roll on two running surfaces 29 of the ceiling guide 2.

The base body 24 has a modulus of elasticity at 20 ° C of 70 kN / mm2 to 100 kN / mm2, preferably approximately 85 kN / mm2, according to EN ISO 6892-1: 2009, a modulus of shear at 20 ° C from 20 kN / mm2 to 60 kN / mm2, preferably approximately 40 kN / mm2 according to DIN 53445, and a density at 20 ° C of 2 g / cm3 to 7 g / cm3, preferably approximately 6 , 7 g / cm3, according to ISO 1183. Roller body 27 has a modulus of elasticity at 20 ° C of 2 kN / mm2 to 4 kN / mm2, preferably approximately 3 kN / mm2, according to ISO 527-1 / -2 for plastics, a shear modulus at 20 ° C of 0.5 kN / mm2 to 1 kN / mm2, preferably approximately 0.8 kN / mm2, according to DIN ISO 1827: 2010- 07 for plastics and a density at 20 ° C of 1 g / cm3 to 2 g / cm3, preferably approximately 1.4 g / cm3, according to DIN EN ISO 1183. In addition, the roller surface 28 of the body of roll 27 has a surface roughness Ra of 0.01 to 3 pm, pr effectorly from 0.05 pm to 2 pm according to DIN ^and N ISO 4287. Especially preferably the roller surface 28 of the roller body 27 is configured isotropically, so that the roller surface 28 does not have any roughness deviation shallow direction-dependent. The roller body 27 further has a diameter of 16mm to 20mm, particularly preferably 18.5mm. Roll surface 28 of roll body 27 has a roll surface width of 5mm to 9mm, preferably 7mm. Furthermore, the transition of the roller surface 28 towards a lateral flank 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 weather according to ISO 62. Water absorption in normal weather designates the percentage weight increase of a body by water absorption in the event of storage at a temperature of 23 ° C and humidity of 50%. Preferably, the water absorption of the roll body in normal weather is kept low. High water absorption causes high flattening of the roller body 27, whereby noise is caused in the rolling of the roller body 27 of the rolling roller 25 on the running surface 29 of the ceiling guide 2.

The roller body 27 also has a water absorption of 1.4% in case of storage in water according to ISO 62. Water absorption in case of storage in water designates the percentage increase in weight of a body by absorption of water in case of storage in water. Roller body 27 of the running roller 25 is configured in such a way that its absorption of water in case of storage in water is kept low. Consequently a flattening of the roller body 27 is reduced, for example in the case of a sliding partition system 1, which is arranged in an external space. Therefore, operation with less noise in different weather conditions can be guaranteed.

Furthermore, the roll body 27 exhibits a flattening of less than 0.7% with respect to the diameter of the roll body 27 after 8 hours of rest of the roll body 27. Due to the reduced allowed flattening the roll body 27 is clearly increased the smooth running of the sliding partition system 1. The flattening of a roller body 27 is measured by exerting a test load of 200 N in the vertical direction on the roller body 27 arranged on a support. Especially preferably the roller body 27 with a diameter of 18.5 mm has a maximum flattening of 0.12 mm after 8 hours of rest.

The running surfaces 29 of the roof guide 2 each have a modulus of elasticity at 20 ° C of 60 kN / mm2 to 80 kN / mm2, preferably approximately 70 kN / mm2, according to EN ISO 6892- 1: 2009, a shear modulus at 20 ° C of 10 to 40 kN / mm2, preferably approximately 27 kN / mm2, according to DIN 53445 and a density at 20 ° C of 2 g / cm3 at 5 g / cm3, preferably approximately 3 g / cm3, according to ISO 1183. In addition, in each case the running surfaces 29 have a surface roughness Ra parallel to the extrusion direction of 0.05 pm to 1.0 pm, preferably approximately 0.5 pm, measured according to DIN EN ISO 4287. In addition, the running surfaces 29 have a surface roughness Ra in the transverse direction in the extrusion direction of 0.7 pm to 1.4 pm, preferably approximately 0.7 pm, measured according to DIN EN ISO 4287. The running surfaces 29 also have a roughness in each case Surface density Rz parallel to the extrusion direction from 3 pm to 5 pm, preferably approximately 3.2 pm, measured according to DIN EN ISO 4287. Furthermore, in each case the running surfaces 29 have a surface roughness Rz in the transverse direction in the extrusion direction from 4 pm to 6 pm, preferably approximately 4.1 pm, measured according to DIN EN ISO 4287 f. Especially preferably a ratio of a surface roughness Ra in the transverse direction in the extrusion direction of the running surface 29 to a surface roughness Ra in parallel to the extrusion direction of the running surface 29 is between 1 , 1 and 3, preferably between 1.1 and 2.

The running surfaces 29 each have internal surface grooves essentially parallel to the direction of travel V of the door leaf element 3. Internal surface groove is to be understood as meaning an essentially linear surface structure from a large number of linear depressions in parallel on the running surface 29, which is generated by the extrusion process. Furthermore, the running surfaces 29 of the roof guide 2 are configured in one piece with the roof guide 2. A compact structure is therefore possible. In addition, potential mounting errors, such as tilting, are eliminated, which could cause rolling noise of the door swing elements 3 in the ceiling guide 2. The ceiling guide 2 has a density of 2 to 5 g / cm3, preferably approximately 3 g / cm3, according to ISO 1183. The running surfaces 29 of the roof guide 2 each have a running surface width, which is greater than the roll surface width of the roller surfaces 28 of the roller bodies 27.

As can be seen from figure 9 each of the roller bodies 27 is housed on the roller carriage 23 by means of a closed ball bearing 31. The roller body 27 has a shaft 32 with two knurls 33, by means of which the roller body 27 is fastened torsionally in the base body 24 of the roller carriage 23 (Figures 9 and 10). Shaft 32 also serves as the inner ring of ball bearing 31. Ball bearing 31 has seven balls which are greased with, for example, lithium saponified grease.

Furthermore, the static surface pressure between the running roller 27 and the running surface 29 of the roof guide 2 amounts to at least 2.5 kg / mm2, preferably between 2.5 and 100 kg / mm2. This produces a squeaky noise elimination in the movement of the door swing elements 3.

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

Furthermore, the momentum of impulse of a door swing element 3, which in the ceiling guide 2 that is displaceably arranged, such as for example the door swing element 3b of FIG. 1, amounts to 8N at 15 N, preferably 10N to 14N, particularly preferably 11N to 13N at a weight of the door swing element 3b of 175kg. After 100,000 cycles, the momentum of the door swing element 3b is in addition to 15N to 21N, preferably 16N to 20N, particularly preferably 17N to 19N. By means of the roller carriage 23 according to the invention as well as the running surfaces29 according to the invention of the ceiling guide 2 a movement of the sliding partition system 1 is allowed with little noise. The wear of the roller bodies 27 is reduced and thus the service life of the roller carriage 23 is clearly increased. Additionally, a squeal of the rolling rollers 25 can be eliminated.

Fig. 11 shows a safety device 35 in a state mounted on the sliding partition system 1, in where the safety device 35 in the event of a glass break serves to retain the clamping profile 4 of the door leaf element 3. Figure 12 shows an exploded view of the safety device 35. The safety device 35 can used, for example, in the fourth door swing element 3d of the sliding partition system 1 of figure 1.

The safety device 35 has a pivot bearing 36, a rotating element 38 and a safety element 40. The pivot bearing 36 is firmly arranged in the ceiling guide 2. The rotating element 38 is connected to the door wing 3 and housed 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 pivot bearing 36 has a sleeve 37 in which the rotating element 38 is rotatably arranged. The rotating element 38 is configured as a pivot with a cylindrical zone and a domed area 39 where the domed area 39 is rotatably positioned in the pivot bearing 36. In particular, the safety device 35 has a support element 43 configured as block which is screwed onto the rotating element 38 by means of a nut 44 and is arranged in a groove of the clamping profile 4. The nut 44 is fixed against a gap by means of a wedge lock washer 45. By means of the safety element 40 it is prevented a vertical movement of the rotary element 38 with respect to the pivot bearing 36. At the same time the torsion of the door wing element 3d is released by the pivot bearing 36.

The security element 40 is configured as a clamping plate that is arranged so that it can be inserted into a housing 22 of the ceiling guide 2 and surrounds the rotating element 38, in particular the cylindrical area of the rotating element 35. For this purpose, the clamping plate has a first notch 41 that is configured in the form of a primitive circle and smaller than the domed area 39, so that the domed area 39 does not protrude through the first notch 41 (FIG. 12). In this way the clamping plate by means of a drag so that it forms in the event of a glass break between the clamping plate and the rotating element 38 prevents the rotating element 38 with the support element 43 and the clamping profile 4 together with it they fall.

The security element 40 also has a second notch 42 to facilitate the assembly procedure of the security element 40 in the housing 22 of the ceiling guide 2 (Figure 12). This second notch 42 is also configured as a primitive disc as the first notch 41, but has a smaller diameter than the first notch 41. The first notch 41 and the second notch 42 are connected through a slit. The housing 22 of the ceiling guide 2 is configured as a slot. Furthermore, the security element 40 is designed in such a way that the security element 40 must expand before it enters the housing 22. In the assembled state, the security element 40 is prevented from expanding by the external sides of the housing 22. Consequently, the security element 40 exerts pressure on the rotating element 35 and acts as a snap lock.

The insertion of the security element 40 in the housing 22 is facilitated by the provision of two outwardly oriented beveled surfaces 96, at an angle of 20 degrees with respect to the direction of insertion at one end directed to the ceiling guide 2 of the element security 40 (figure 12).

In order to securely hold a glass panel 34 in a door swing element 3, the glass panel 34 is force-bound and cohesively bonded to the top and bottom door track 5 (Figures 13-15). The glass panel 34 can be composed for example of a high security composite safety glass, whereby the level of security is increased to an extreme extent. In addition, high security composite safety glass offers thermal protection through a low thermal transition coefficient.

In this regard, the glass panel 34 to both centerline M, as shown in Figure 17, is coherently joined on two sides along the width of the glass panel 34 with the door rails 5. In particular the glass panel 34 is clamped on door rail 5 and glued with door rail 5. To establish the clamp connection between door rail 5 and glass panel 34, glass clamping elements known per se can be used. The central line M is to be understood as the central axis of the door wing element 3 in the vertical direction which is perpendicular to the direction of travel V.

The door track 5 has two loading openings 50 that open into two adhesive chambers 47 and serve to load the adhesive. Alternatively, both adhesive chambers 47 can be supplied with adhesive through a single inlet opening or loading opening. In Figures 13 to 15 only a partial area of a door wing element 3 is shown, where only one adhesive chamber 47 with the corresponding inlet opening 50 can be seen.

An intermediate layer 48 is inserted between the door track 2 and the glass panel 34, where the intermediate layer 48 has two notches 49 configured in the form of a channel (Figures 13 and 16). The adhesive chambers 47 are defined by the notches 49 of the intermediate layer 48 as well as the surfaces of the door track 2 and the glass panel 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 swing element 3.

The intermediate layer 48, which is shown separately in FIG. 16, is configured in a single piece and has in each case its distal ends a stamping for the configuration of the adhesive chambers 47.

To facilitate a symmetrical and uniform distribution of adhesive force, the two adhesive chambers 47 are essentially identical.

Each adhesive chamber 47 preferably has a volume between 0.5 to 30 cm3, particularly preferably between 1 to 10 cm3. By means of this volume a sufficiently large adhesive deposit is provided for a sufficiently strong adhesive bond. The adhesive chambers 47 each have a length in the direction of movement of the door wing element 3 from 0.05 to 0.2 times the width z of the door leaf element 3. An adhesive length is therefore provided. sufficient for the adhesion of the glass panel 34 and distribution of adhesive force.

The door track 5 preferably comprises at least two, in particular preferably at least three force input points 89, which are configured as a bolted joint and have a horizontal distance from each other. Figures 13 and 15 show two such force introduction points 89. Preferably the clamping force, which acts through a force introduction point 89 through the intermediate layer 48 towards the glass panel 34, amounts to between 2500 to 15000N, particularly preferably between 5,000 to 10,000N.

It is very especially preferable that a force introduction point 89 and an adhesive chamber 47 have a coincidence zone, so that the force introduction point 89 is arranged in the area of the adhesive chamber 47 (Figure 13). For this reason, a particularly advantageous and safe sealing of the adhesive chamber 47 can be realized.

The intermediate layer 48 preferably has a fringe-like configuration with a quadrangular cross section. For this reason, it is possible, in particular, to make thin clamping elements for glass with a low construction height. In particular 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 is configured that guarantees a guaranteed flow and distribution of an adhesive in the adhesive chambers 47. Furthermore, in these material thicknesses, a sufficiently good pressure distribution can be provided in the force drag towards glass panel 34.

The basic shape of the adhesive chambers 47 is defined, as already described, preferably by stamping on the intermediate layer 48. Basically a large number of basic shapes are conceivable in this case for the adhesive chambers 47, for example a rectangular shape, a square shape, an ellipse shape, or a circular shape.

The basic shape of the adhesive chambers 47 is rectangularly symmetrical with respect to the central longitudinal axis of the intermediate layer 48 as a strip. Hence the same watertight effect is achieved essentially on both sides of the longitudinal extension of the adhesive chamber 47. In particular, in the case of adhesive chambers 47 rectangularly shaped in the basic shape, the ratio of the width of the intermediate layer 48 of the fringe type with respect to the width of the rectangular adhesive chamber 47 is between 1.5 to 3.5, preferably between 2 to 3. Therefore, on the one hand, a sufficient sealing effect is provided with respect to the adhesive chambers 47, and on the other hand also a sufficient pressure distribution in the force drag on the glass panel 34.

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

It is further advantageous for the door track to extend from 80% to 100%, in particular from 90% to 100% of the total width of the door leaf of a door leaf element 3.

The intermediate layer 48 can have at least one self-adhesive layer on one side, which allows the intermediate layer 48 to be easily attached to the door track 5. Furthermore, this adhesion contributes to a further sealing of the intermediate layer 48 with respect to the track 5, in particular to an injection of the adhesive into the adhesive chambers 47 defined by the intermediate layer 48. Naturally it is also possible to provide in each case a self-adhesive layer on two sides of the intermediate layer 48.

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

In order to achieve an optimized pressure distribution and a reduction in local pressure peaks of the door track 5 on the surface of the glass panel 34, the intermediate layer 48 has a compressibility of 5% to 25%, especially preferably 5% to 15%, measured according to ASTM F36 / J standard.

To further optimize the pressure distribution, the intermediate layer 48 has an elastic recovery of 30% to 60%, preferably 40% to 50%, measured according to ASTM F36 / J.

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

The door track 5 has two discharge openings 90 that serve to expel the air from the adhesive chambers 47 and to visualize the level of adhesive loading. The closing elements not shown are provided for closing the loading openings 50 and the discharge openings 90 in the sliding partition system 1.

The geometry of the adhesive chambers 47 as well as the loading openings 50 and the discharge openings 90 are preferably adapted to the rheological properties of the adhesive, in particular towards the injection time, so that optimum wetting of the the surfaces to be bonded, a complete filling of the adhesive chambers 47, as well as a simple and safe handling of the adhesive injection for the user within the adhesive opening time. Opening time extends the maximum period of time within which the assembly parts must be bonded. Advantageously an adhesive, which is used for the sliding partition system 1 and the method for attaching a glass panel 34 to a sliding partition system 1 has an opening time of between 1 to 10 min, preferably between 2 to 5 min.

Furthermore, the adhesive used preferably has a tensile and shear strength after approximately 5 to 15 min, preferably after approximately 7 to 10 min, of at least approximately 5 MPa, preferably at least approximately 7 MPa at 23 ° C measured according to the ASTM D 1002 standard. This ensures that close post-processing in time or installation of the glued door swing element 3 can be performed.

In order to facilitate, in addition to force drag, also a sufficient adhesion effect for the support of the glass panel 34 in or on the door track 3, the adhesive has, in the cured state, a tensile and shear strength of at least 10 MPa , particularly preferably at least 20 MPa, measured according to ASTM D 1002 on an aluminum substrate.

The door track preferably has a surface facing the adhesive chambers 47 with a surface roughness Ra of 0.5 pm to 5 pm, preferably 1 pm to 2.5 pm, measured according to DIN EN ISO 4287, whereby an improved adhesion effect of the adhesive is caused on the substrate.

Each of the discharge openings 90 is arranged at the vertical end of the door swing element 3, that is to say on its vertical front side. It is made possible therefore that the injection of the adhesive can be observed after the complete filling of the adhesive chamber on the front side of the door wing element 3 during injection of the adhesive, in particular taking into account ergonomic aspects of the injection process of adhesive this arrangement of discharge opening 90 has been found to be advantageous.

The loading opening 50 and the discharge opening 90 for each adhesive chamber 47 are arranged at the distal ends of the adhesive chamber 47. Thus, in particular, a complete filling of the adhesive chambers 47 with adhesive is ensured.

It is further preferable that the discharge openings 90 are shaped in the intermediate layer 48, so that no flow has to be provided in the door track 5. Therefore only the loading openings 50 are provided to the user, preferably on the side front on the door track 5. This increases the safety of handling and mounting the system.

To further improve this it can be provided that the discharge openings 90 and the charge openings 50 have cross sections distinct from each other so that a coupling with an adhesive application device is allowed exclusively through the charge openings 50.

The discharge openings 90 are tapered in each case with respect to the adhesive chambers 47. Advantageously, each of the discharge openings 90 is configured as a channel-shaped slit in the intermediate layer 48.

The opening width of the slit preferably with respect to the width of the basic shape of the adhesive chamber 47 defined by stamping on the intermediate layer 48 amounts to between 0.1 to 0.5, preferably between 0.15 to 0, 25. For this reason, when filling the adhesive chamber 47 and at the outlet of the adhesive, a hydraulic resistance large enough that it favors a complete discharge of the adhesive chamber 47 and at the same time the user can be signaled through the haptic by the high resistance already before the adhesive comes out from the discharge opening 90 that the process of Adhesive injection will be finished soon. To facilitate a sufficient reaction time for the user between the increase in resistance described above and the exit of the adhesive from the discharge opening 90, the length of the channel-type discharge opening 90 with respect to the length of the adhesive chambers Channel type 47 has a ratio of 0.1 to 0.75, preferably 0.25 to 0.5.

The procedure for attaching a glass panel 34 to the sliding partition system 1 is explained below.

In a first stage, a non-bearing connection is produced between the door rail 5 and the glass panel 34 by clamping the door rail 5 on the glass panel 34 with a reduced clamping force, which serves only for fixing position of the door track 5 on the glass panel 34 after the intermediate layer 48 on which the two notches 49 have been stamped has been inserted between the door track 5 and the glass panel 34. In a second step, achieves a supporting connection between the door track 5 and the glass panel 34 by adhesion of the door track 5 to the glass panel 34.

For a better understanding of the second stage of the fastening procedure, an adhesive injector 51 is shown in FIGS. 13 to 15. Adhesive, for example a two-component adhesive, is injected through the inlet opening 50 shown by the adhesive injector 51 in the adhesive chamber 47. The adhesive is autonomously distributed throughout the adhesive chamber 47. The injection of the adhesive ends when adhesive comes out from the discharge opening 90. Then the inlet opening 50 and the discharge opening 90 it is closed with closing elements not shown and by means of trims, which are installed on the door track 5, they are elegantly covered.

By adhering the glass panel 34 to the door track 5 the functionality of the door leaf element 3 is ensured in the long term. In addition, the simple feeding of the adhesive speeds up the assembly.

Figures 17 and 18 show a partial area of the third door swing element 3c of the sliding partition system 1, where an integrated door actuator 52 is provided in the door swing element 3c. Preferably the door actuator 52 is integrated in the door track 5 and connected through a lever arm 53 with a sliding element 54, where the sliding element 54 is guided in the clamping profile 4 in a guide 55. As Alternatively, the door actuator 52 can be arranged on the clamping profile 4 and the sliding element 54 on the door rail 5. The door swing element 3c is shown in Figures 17 and 18 in the closed state.

The guide 55, which is configured in one piece with the door rail 5, is arranged at one end of the fastening profile 4 separated from the ceiling guide 2. In particular, the guide 55 is configured as a slot.

The clamping profile 4, the guide 55, the sliding element 54 and the ceiling guide 2 are arranged on the center line M. Therefore a compact structure is possible.

As can be seen from figure 18, the door swing element 3c has a first rotary axis 56 around which the door rail 5 is pivotally arranged with respect to the clamping profile 4. The first rotary axis 56 is arranged in the clamping profile 4 and the door track 5 in force drag. In particular the rotary axis 56 is immobilized on the clamping profile 4 and on the door track 5. The rotary axis 56 is vertically oriented.

Figure 19 shows a perspective view of the door swing element 3c, where the door rail 5 is shown with respect to the fastening element 4 in a pivoted position. In this sense, the door actuator 52 preferably has an opening angle a of 180 ° and an opening angle b of 90 ° at a zero position of the door actuator 52. Zero position is to be understood as the position in which the profile Clamp 4, door rail 5, door actuator 52 and lever arm 54 are located on the common center line M. In the zero position the door actuator 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 swing element 3c can rotate 90 degrees in both directions with respect to the clamping profile 4.

The zero position of door actuator 52 is adjustable. Preferably, the zero position can be adjusted through a set of door actuator construction elements 52 arranged on the door track 5 at an opening angle of 0 degrees. To mount the door swing element 3c in the sliding partition system 1, the ceiling guide 2 is first installed on a ceiling of the building. Thereafter the sliding element 54 is inserted into the guide 55, where the sliding element 54 in an assembled state is displaceably arranged in the guide 55. The door wing element 3c is then inserted into the ceiling guide 2. TO Thereafter, the door actuator 52 is connected through the lever arm 53 with the sliding element 54. As an alternative, the installation of the ceiling guide 2 in the ceiling and the insertion of the sliding element 54 in the guide 55 can be carried out in the order reverse. Furthermore, the insertion of the sliding element 54 in the guide 55 can be carried out after the insertion of the door wing element 3 in the ceiling guide.

In order to be able to adapt the operation of the door swing element 3c depending on the application, the third door swing element 3c, as already mentioned, has an interlocking mechanism 6 on two sides. By means of the two-sided locking mechanism 6, the pivoting capacity of the door track 5 with respect to the clamping profile 4 and / or the mobility of the door swing element 3c with respect to the ceiling guide 2 can be prevented.

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

The locking mechanism 6 is provided with a locking element 57 which is arranged so that it can move between a first position A, a second position B and a third position C in the clamping profile 4. The first position A, the second Position B and the third position C are shown in Figures 22 to 24. As an alternative, the locking mechanism 6 can be movably integrated in the clamping profile 4. By means of the locking mechanism 6, an interlocking between the clamping profile is allowed. clamping 4 and the ceiling guide 2 and / or between the clamping profile 4 and the door track 5. In particular, in the first position A of the locking element 45 the mobility of the door swing element 3 in the guide of the roof 2 is locked. In the second position B of the locking element 57, the pivoting capacity of the door rail 5 with respect to the clamping profile 4 is prevented. Furthermore, in the third position C of the locking element 57, the mobility and pivoting capacity of the element is inhibited. door swing on ceiling guide 2.

Preferably the locking element 57 is rotatably arranged around a second rotary axis R in the clamping element 4, where the second rotary axis R is perpendicular to the larger surface of the door swing element 3c or to the center line M Accordingly, the locking element 57 can be twisted to the first position A, the second position B and the third position C. In a particularly preferable way the locking element 57 comprises a dividing sprocket element 59, which can be directly driven by means of a worm 60. By self-retention of worm 60 a secure interlocking is possible. Otherwise, the locking element 57 has a reinforcing area 86, thereby facilitating a secure and stable locking.

The locking mechanism 6 further comprises a first housing construction element 61, a second housing construction element 62 and a third housing construction element 63.

The first housing construction element 61 is connected to the ceiling guide 2 outside the ceiling guide 2. In particular, the first housing construction element 61 has a stop (not shown) with which the dividing sprocket element 59 and the reinforcing zone 86 are in contact in the first position A (figure 22). The reinforcing area 86 furthermore has sliding properties so as to be able to slide on at least one internal surface of the first housing construction element 61, in particular of an internal surface that extends in the width-z direction of the door wing element 3. By Accordingly, the locking element 45 is guided in a way in the first housing construction element 61.

The locking element 57 protrudes in the first position A through the second housing component. The locking element 57 configured as a dividing sprocket element 59 has a radius r such that a relationship between the radius r and a length x in the vertical direction, which extends between the rotary axis R and an external surface directed to the first constructive element housing 61 of the third housing construction element 63 is located in a range of 2 to 3 (Figure 21). Therefore, a stable interlocking in the first position A of the interlocking element 57 is possible.

The second housing construction element 62 is connected on the external side with the door track 5 and has a housing groove 64 in which the locking element 57 engages in the second position B (FIG. 23). In order to guarantee a stable interlocking in the second position B, the interlocking element 57 has an arm area 65 that engages in the housing groove 64 of the second housing element 62. In the second position B, the arm area 65 is held around a pin 66, which is arranged parallel to the second rotary axis R of the locking element 57 in the second housing component 62. The locking element 57 is configured such that in the third position C the locking element 57 is It partially engages in the first housing construction element 61 and partially in the second housing construction element 62 (Figure 24). The third housing construction element 63 is arranged in the clamping profile 4 and serves as a housing for the locking element 57 and the worm screw 60. To make a compact structure of the third housing construction element 63 the rotary axis R is arranged out of phase in the third housing construction element 63 on the sides in the width z direction of the door wing element 3 (FIG. 21).

In order to modify the locked state of the door leaf element 3c, the endless screw 60 is operated by means of a tool. For this purpose, an access notch 83 is provided in the second housing construction element 62 through which access to the worm screw 60 is guaranteed.

To display the latching condition of the door swing element 3c, the latching mechanism 6 is provided with a display kit 58 which is partially coupled with the latching element 57. The locking mechanism 6 is described by means of Figures 20 to 24.

The partial coupling of the display equipment 58 with the locking element 57 means that not all the components of the display equipment 58 are connected to the locking element 57. In particular, the display equipment 58 has a first display element 67 and a second display element 68. The first display element 67 is rotatably disposed in the locking element 57 and the second display element 68 is rotatably coupled with the locking element 57. In addition the first control element Display 67 and second display element 68 partially overlap. This overlap is produced by the shape of the first display element 67 and the second display element 68. In particular, the first display element 67 is configured as a shaped plate and the second display element 68 is configured as a plate. essentially rectangular. To allow easy recognition of the latching condition the first display element 67 and the second display element 68 are provided with different colors.

The display unit 58 also has a first notch 69 and a second notch 70 which are arranged in the third housing construction element 63. By means of the first notch 69 and the second notch 70, a relative position is given between the first display element 67 and the second display element 68. The first display element 67, which can generally be seen through the first notch 69 and the second notch 70 can be covered in the first notch 57 and / or in the second notch 58 by means of the second display element 68 according to the locked state of the door swing element 3c.

Thus, in the first position A of the locking element 57, which corresponds to a blocking of the mobility of the door swing element 3c in the ceiling guide 2, the first display element 67 in the first notch 69 is covered through the second display element 68 and in the second notch 70 it is visible (figure 22). In the second position B of the locking element 57, which corresponds to a blocking of the pivoting capacity of the door track 5 with respect to the clamping profile 4, the first display element 67 is covered in the second notch 70 by the second control element visualization 68 and in the first notch 69 is visible (figure 23). In the third position C of the locking element 57 the first display element 67 is covered in the first notch 69 and in the second notch 70 by the second display element 68 (FIG. 24). This means a blocking of the mobility and pivoting capacity of the door swing element 3c in the ceiling guide 2.

In order to simply and reliably decrease the air flow or to guarantee improved sealing of the sliding partition system 1 and at the same time protect the glass edges of the glass panels 34 in the sliding partition system 1, several joints are provided in the form of brushes. In particular, two brushes 71 are arranged in each case on both sides of the center line M in the clamping profile 4 of a door swing element 3 to seal a gap towards the ceiling guide 2 (Figures 25 and 26). The brushes 71 are the first brushes 71. In addition, two first brushes 71 can be arranged in each case on both sides of the center line M in the lower door rail 5 to seal a gap to the ground (not shown).

In figure 26 a partial area of the third door swing element 3c of figure 1 is shown. As can be seen from figure two second brushes 72 are arranged in each case on both sides of the central line M on a lateral surface of the clamping profile 4 to seal a gap to a clamping profile 4 of a neighboring door leaf element 3. Furthermore, two additional second brushes 72 are each arranged on either side of the center line M on a side surface of the door track 5 to seal a gap to a door track 5 of a continuous door swing element 3. In the case of the door wing elements 3, in which there is no pivoting of the door rail 5 with respect to the clamping profile 4, the second brushes 72 on the same side may be configured with respect to the center line M of only one piece. 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 swing element 3, are located within a virtual plan E (Figure 26). This means that the first brushes 71 and the second brushes 72 are arranged in such a way that their central axes define a plane. Consequently, a brush seal is configured surrounding the door swing element 3, whereby, for example, improved protection from external influences is allowed before. Each of the first brushes 71 is displaceably arranged in a first brush housing 74, wherein the first brush housing 74 has a U-shaped area 75 in cross section and is removably arranged in the profile of clamping 4. Clamping profile 4 has a channel 76, in which the first brush housing 74 by means of a force drag connection 77, in particular a key connection, is arranged in the channel 76.

Furthermore, the first brush housing 74 has a first housing area 78 and a second housing area 79 where the first housing area 78 is arranged in a vertical direction above the second housing area 79. Preferably the first housing area 78 and the second housing area 79 are configured as introduction channels. In this way the first brushes 71 can be easily mounted on the door leaf element 3 and adjusted in a vertical direction when the first brushes 71 are inserted in each case in the first accommodation area 78 or in the second accommodation area 79. Furthermore the second brushes 72 are housed in second brush housings 85 movably in the clamping profile 4 and in the door rails 5 of the door wing element 3. Furthermore the second brush housings 85 are arranged on both sides of center line M. The second brush housings 85 are configured as grooves in which the second brushes 72 are housed in a form-fit manner. Figures 27 and 28 show a first brush 71 and a second brush 72.

The first brush 71 comprises a first base area 81 and a first lining 82, wherein the first lining 82 in the cross section is configured as a trapezoid. Similarly, the second brush 72 has a second base area 87 and a second lining 88 that are also trapezoidal in cross section.

The first lining 82 of the first brush 71 is configured of polyamide, preferably polyamide 6.6, in particular with a fiber diameter of the first lining 82 of from 0.025mm to 0.25mm, most especially preferably from 0.05 to 0, 2 mm.

fiber diameter of the second lining 88 from 0.01 mm to 0.2 mm, very particularly preferably from 0.025 to 0.1 mm.

The first trim 82 may preferably have a first trim inclination of 0 ° to 10 ° in the longitudinal direction of the first brush 71 and the second trim 88 a second trim inclination of 0 ° to 10 ° in the longitudinal direction of the second brush. Accordingly, the first second lining 88 of the second brush 72 is configured of polypropylene, in particular with a brush it can better adapt to different shapes of the ceiling guide or to temperature fluctuations to guarantee sufficient tightness. Furthermore, potential deviations from the relative position caused by mounting between the fastening profile and the ceiling guide and / or between adjacent door leaf elements can be compensated by tilting the first trim and / or the second trim.

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

Furthermore preferably the flexural stiffness of the first brush 71 is greater than the flexural resistance of the second brush 72. The bristles or fibers from which the linings 82, 88 of the brushes 71, 72 are configured have sufficient rigidity to flexion to present a sufficiently good seal of the first brush 71 and the second brush 72 with respect to mechanical or pneumatic influences, but on the other hand so as not to cause any damage to the surfaces of floor guides and / or ceiling guides during movement of the door swing elements 3 in the sliding partition system 1. This is important, since in particular in the floor area, in addition to abrasion and scratch resistant mineral floor coverings, more and more materials are also used , such as wood whose propensity for abrasion or scratches is clearly higher. Especially preferably the material of the first lining 82 has a first flexural stiffness between 0.07 Nmm2 and 0.3 Nmm2, preferably between 0.07 Nmm2 and 0.15 Nmm2. The material of the second lining 88 has a second flexural stiffness of 0.064 Nmm2 f. The flexural stiffness measurement can be carried out according to DIN EN ISO 22254.

The gap between the two adjacent door swing elements 3 may vary over time due to frequent use or relative movement to each other as well as thermal expansion or thermal contraction. The interstices may also be different between different adjacent door leaf elements. Since the second lining material of the second brush 72 is configured soft, these variations can be compensated. The variations in the gap between the fastening profile 4 and the ceiling guide 2 are as a rule minor, in particular when a single one-piece ceiling guide 2 is used for all the door swing elements so it is based lower flexural stiffness.

The first brush 71 has a first plastic sheet 80a and the second brush 72 a second plastic sheet 80b, where the first plastic sheet 80a is arranged in the center in the first brush 71 and the second plastic sheet 80b in the second brush 72.

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

To meet the different sealing requirements, as already described, the first plastic sheet 80a is preferably configured in one layer and the second plastic sheet 80b is configured in two layers. The first plastic sheet 80a preferably has a first sheet thickness between 30 pm and 200 pm, particularly preferably between 50 pm and 150 pm. The second plastic sheet 80b has a second sheet thickness between 30 pm to 200 pm, particularly preferably between 50 pm to 150 pm. Through the thickness of material the flexibility of the first brushes 71 and the second brushes 72 can be controlled. The specified sheet thicknesses show an optimal sealing effect.

Advantageously a first sheet height of the first plastic sheet 80a in the first brush 71 amounts to between 100% and 150%, preferably between 105% and 125%, of the first trim height of a first trim 82 of the first brush 71 The second plastic sheet 80b on the second brush 72 has a second blade height between 100% and 150%, preferably between 105% and 125%, of the second trim height of a second trim 88 of the second brush 72.

In this context it is advantageous when the first plastic sheet 80a in the state arranged in the first brush 71 is arranged inwardly retracted by 2% to 20%, preferably 5% to 10%, with respect to a first brush height , towards the first base area 81 of the first brush 71 and the second plastic sheet in the state arranged in the second brush 72 is arranged receding inwards by 2% to 20%, preferably 5% to 10%, with respect to at a second brush height, towards a second base area 87 of the second brush 72. For this reason, a good fit of the second plastic sheets 80b of two adjacent door leaf elements 3 occurs in the closed position and therefore an improved sealing effect. To guarantee a sufficient seal without damaging the floor and / or the ceiling guide 2, preferably each of the first brushes 71 with a clamping pressure of 0.01 N / mm2 to 0.5 N / mm2 contacts the floor and / or roof guide 2.

Especially preferably the second lining 88 of second brushes 72 facing two adjacent door leaf elements 3 is engaged in the closed position of the door leaf elements 3 in the sliding partition system 1. It can therefore be ensured that the adjoining door wing elements 3 remain sealed against each other also when the gap by for example wear of the second brush 72 increases.

According to a preferred configuration, the second gaskets 88 of the second brushes 72 facing two adjacent door leaf elements 3 in the closed position of the door leaf elements 3 in the sliding partition system 1 have a degree of overlap of 2% to 20%, preferably from 5% to 15% with respect to the second trim height of the second brushes 72.

The two layers of the second plastic sheet 80b in the state mounted on the second brush 72 have a substantially equal second sheet height. This produces a uniform load and with it a comparable wear of the two layers.

Furthermore, the two layers of the second plastic sheet 80b are directly adjacent to each other, in particular without an intermediate arrangement of bristle fibers. Consequently, the two layers form a unit that can better withstand mechanical or pneumatic influences and causes improved sealing.

In particular the second plastic sheets 80a of second brushes 72 facing two adjacent door leaf elements 3 in the closed position of the door leaf elements 3 in the sliding partition system 1 have a degree of overlap of 1% to 20%, preferably 2% to 10% with respect to the second blade height of the second brushes 72. By superimposing the second plastic blades 80b in the closed position, the sealing effect can be further optimized.

Furthermore preferably the second brushes 72 of the opposite second brushes 72 of two adjacent door leaf elements 3 are essentially identical.

The sliding partition system has in particular an air permeability with respect to the joint length of 5 m3 / hm to 20 m3 / hm, preferably 10 m3 / hm to 20 m3 / hm, in a pressure difference of 200 Pa, measured according to EN1026 standard.
