Description

The invention relates to a sliding wall system with at least one ceiling guide, which has at least one rail and at least one switch.

Sliding wall systems and their door panels are known, for example, in multi-leaf entrance doors, wall sliding elements used as a room divider or wall elements in front areas of buildings, especially in restaurants and shops, to keep the shop open or closed according to the weather. The door leaf elements are usually movably received in ceiling mounted ceiling guides. In this case, the individual wing elements can be parked in a lateral position, so that there is no hindrance to the entering public traffic. Such systems are for example off US3397487 and from US3614803A known.

Usually, switches are required in addition to the rails in the ceiling guides for the preparation of such parking positions, also called stations.

The rails are regularly made of extruded profiles, whereas the above-mentioned switches are regularly machined due to their geometry.

Fig. 1 shows a perspective view of a sliding wall system 1 according to the present invention. The sliding wall system 1 comprises a ceiling guide 2 and four door leaf elements 3, which are arranged side by side in the longitudinal direction L of the sliding wall system 1 in the ceiling guide 2. All door panels 3 have the same width z. The ceiling guide 2, which is designed as a one-piece rail 10, has a length which corresponds to a four times the width z of the door leaf elements 3. Alternatively, the ceiling guide 2 may be composed of a plurality of ceiling guide elements.
Furthermore, the sliding wall system 1 is arranged on a frame 9. In particular, the ceiling guide 2 is provided on an upper part of the frame 9, which is attached to a ceiling, not shown, of a building. Alternatively, the ceiling guide 2 may be attached directly to the ceiling of the building. A lower part of the frame 9 is fixedly connected to a floor of the building, also not shown.

In particular, the sliding wall system 1 of the Fig. 1 a first door leaf element 3a, a second door leaf element 3b, a third door leaf element 3c and a fourth door leaf element 3d, which may be provided with certain functions. The first door leaf element 3a and the fourth leaf element 3d are pivotally arranged in the ceiling guide 2 and rotatably mounted on the floor, wherein the second door leaf element 3b in the ceiling guide 2 can only be moved. Furthermore, the third door leaf element 3c is arranged pivotably and displaceably in the ceiling guide 2. Thus, the first door leaf element 3a and the fourth leaf element 3d serve as rotary or pendulum wings, the second leaf element 3b as a sliding leaf and the third leaf element 3c as a rotary sliding wing.
All door leaf elements 3 each have a fastening profile 4, two door rails 5 and a glass pane 34, which are arranged between the door rails 5. The fastening profiles 4, the door rails 5 and the glass panes 34 are identical in all door leaf elements 3. The one door rail 5 of each door leaf element of the door leaf elements 3a, 3b, 3c and 3d is arranged on one of the ceiling guide 2 end facing and the other at a bottom facing the end.
Furthermore, the sliding wall system 1 comprises three locking mechanisms.
The third door leaf element 3c has a locking mechanism 6, which is a two-sided locking mechanism. As a result, a rotation of the door rails 5 and the glass pane 34 of the third door leaf element 3c, which are firmly connected to one another, can be prevented with respect to the fastening profile 4 of the third door leaf element 3c. Further, by the two-sided locking mechanism. 6 a displacement of the third door leaf element 3c in the ceiling guide 2 in a direction of displacement V are blocked. The displacement direction V is determined by the shape of the ceiling guide 2. Here, the shift direction V corresponds to the longitudinal direction L of the sliding wall system 1. The structure and function of the double-sided locking mechanism 6 will be described later with reference to FIGS. 20 to 24.

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

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

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

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

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

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

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

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

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

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

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

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

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

The rails 10 each have a first Außenflächenrillung and the switch 11 on a second Außenflächenrillung on their adjacent visible surfaces in the extrusion direction, which has a substantially parallel to the direction of displacement V of a door leaf element 3 groove orientation.

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

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

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

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

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

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

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

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

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

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

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

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