Description

The invention relates to a partition wall system for interiors in buildings, in particular for offices, with at least one ceiling-side rail and one or more partition walls, each partition wall being guided at the head end with at least one running shoe within the rail in its longitudinal direction, and wherein the partition wall is guided at the bottom with the aid supported by at least one bottom roller.

Partition wall systems of the structure described at the beginning are used in interiors in order to be able to undertake a flexible division of the base area and, for example, to partition rooms. In contrast to partition walls that can be moved back and forth on a floor, such rail-guided partition wall systems have the general advantage that a largely soundproof and opaque closure is achieved because the partition in question, starting from the floor-side roller, is at the base of the partition wall up to the head-side end of the Partition wall with the running shoe provided there ensures a predominantly complete closure of the partitioned area without the partition wall tipping over. In addition, the guided movement facilitates operation.

In this case, the ceiling-side rail can in principle be attached to a room ceiling of the interior space equipped in this way or hung opposite the room ceiling, so that a free space still remains between the ceiling-side rail and the room ceiling. Either way, with such partition wall systems a functionally appropriate segmentation of the appropriately equipped interior space into individual room components succeeds, namely flexibly.

Another factor contributing to this is that, depending on the course of the ceiling-side rail or the number thereof, very different segment designs are possible in an interior. Such partition wall systems are generally known from practice. In the prior art according to DE 40 22 432 C1 describes a wall system for cabinets or partitions. The individual walls are equipped, for example, with profile rails that are attached to the front edges and are releasably clipped into them. As a result of this, the known partition walls can only be moved relatively rigidly in the room and, in particular, today's increased requirements for the most efficient noise protection possible are not taken into account.

The invention is based on the technical problem of further developing such a partition wall system in such a way that flexible installation and wall design is made available, taking into account a form that is both visually appealing and sound-absorbing.

To solve this technical problem, a generic partition wall system for interiors in buildings is characterized within the scope of the invention in that the partition wall is connected to the running shoe so as to be rotatable about a largely vertical axis.

This means that the at least one running shoe that ensures the head-side guidance of the partition wall within the rail has an additionally defined axis of rotation according to the invention, which overall ensures that the partition wall can be rotated about a largely vertical axis or the vertical axis of rotation in question. For this purpose, each partition is preferably equipped with a (single) running shoe, which is usually connected centrally to the partition on the head side. In addition, it has proven to be beneficial in this context if the running shoe with a Rotary bearing is equipped for engaging a predominantly vertical bearing journal.

In this way, the partition in question is initially equipped with the help of one (single) running shoe on its head side. The running shoe engages in the rail and can in this way be guided in the longitudinal direction within the rail. The same applies to the partition wall connected to the running shoe. Since the partition wall is also connected to the running shoe in a predominantly vertically rotatable manner, because the running shoe is equipped for this purpose with a pivot bearing for engaging a predominantly vertical bearing pin, the partition wall can not only be moved along the longitudinal direction of the rail, but in principle can be any conceivable Make an angle with the longitudinal extension of the rail and be set up in this way.

In fact, the partition wall is supported on the foot side with the help of at least one floor-side roller. Usually two bottom-side rollers or two bottom-side roller pairs are provided, which are predominantly arranged on both vertically oriented longitudinal edges of the partition or in its vertical extension. Since the floor-side roller or the several floor-side rollers are also connected to the underside of the partition so that they can rotate about a vertical axis, the roller or rollers can easily follow any rotary movement or inclination of the partition with respect to the running rail.

The bearing pin for engaging the rotary bearing of the running shoe is generally connected to a fastening anchor connected to the head side of the partition wall. In order not to burden the pivot bearing unnecessarily, the weight of the partition is completely or almost completely of the one or added to the multiple bottom rollers. The pivot bearing and the running shoe, on the other hand, exclusively or almost exclusively ensure the guidance of the partition without having to absorb or absorb weight forces themselves. As a result, the ceiling-side rail can be made mechanically simple and light, because the rail practically no weight forces are absorbed by the partition, but the interaction between the running shoe and the rail only serves to guide the partition within the room. In order to ensure that the running shoe is guided with as little friction as possible within the rail, the running shoe is generally equipped with rollers and, with the aid of these rollers, is guided within the rail designed as a hollow profile. The rollers on the running shoe are connected to the running shoe in such a way that the running shoe has at least one front and one rear roller. The respective roller is predominantly mounted so that it can rotate about a horizontal axis, so that the roller can be moved perfectly for guidance within the rail, which is also largely horizontally oriented.

As already explained, the bearing pin for the rotatable mounting of the respective side wall opposite the running shoe is connected to a fastening anchor, which in turn is coupled to the partition wall on the head side. The fastening anchor is mostly U-shaped in cross section. In this case, the bearing pin can be connected to the U-shaped fastening anchor in the area of a U-base of the latter. The partition wall is largely designed to be noise-absorbing with a frame and noise protection filling. This means that the noise protection filling is enclosed by the frame. The noise protection filling is typically a foamed plastic filling. Here, for example, a foamed plastic such as Styropor®, i.e. expanded polystyrene, has proven to be particularly beneficial. In addition, the partition has advantageous over the frame, which receives the noise protection filling in its interior and serves to hold it. The frame is mostly a wooden frame in order to set the weight of the partition used according to the invention as low as possible.

The partition wall is also equipped with a front coating. Most of the time, the partition wall has a corresponding coating on its two opposing visible sides or front sides. In this context, it has proven particularly useful when the coating has perforations. Sound hitting the partition wall can get into the interior of the frame via these perforations and hit the noise protection filling here, so that particularly efficient sound insulation is provided. The perforations implemented at this point have an opening diameter that is typically below 10 mm, so that the perforations are not or practically not noticeable visually in the otherwise continuous coating.

If a non-woven layer is used as the coating, additional perforations are not necessary because the non-woven layer has the necessary perforations anyway due to the open structure and transmits the sound to the interior, which is then absorbed by the noise protection filling and converted into thermal energy. In principle, however, the coating can also be a wood layer and / or plastic layer and / or metal layer. In the latter cases, perforations will usually be used in order to obtain the desired noise insulation. In addition, the layers in question and mentioned can provide the coating of the frame in whole or in part. Of course, combinations such that the coating partially has the fleece layer and partially a plastic layer. Combinations such that the coating is made up of a laminate made up of a plastic layer and a wood layer are also conceivable and are encompassed by the invention.

Since the frame accommodating the noise protection filling in its interior is generally made of wood, for reasons of stability the partition wall usually has a U-profile, for example metal, on the base and head side, which extends over the frame. A U-profile made of aluminum has proven to be advantageous here, because in this way the total weight of the partition in question can be kept particularly low. With the help of the U-profile, which extends over the frame at the foot and head, on the one hand the running shoe engaging in the rail and on the other hand the floor-side roller or several floor-side rollers can be easily connected to the frame (made of wood), without any stability problems or frame breakage are to be feared.

In addition, it has proven useful if the partition is equipped with connecting means on the longitudinal edge for coupling a plurality of partition walls in, for example, the longitudinal direction. These connecting means on the longitudinal edge can be ones which act magnetically. Here, for example, magnetic strips on the longitudinal edges of the partition walls have proven to be particularly advantageous. In this way, the partition walls can be joined together on the longitudinal edge side and thereby define a closed wall that can be opened again without problems if necessary. This is because the individual connecting means interacting with one another allow the two adjacent longitudinal edges of the partition walls temporarily coupled to one another to be released without any problems and at any time. As an alternative or in addition to the magnetic strips on the longitudinal edge Connecting means, it is also conceivable to work with Velcro strips or other temporarily acting connecting means at this point.

As a result, a partition wall system for interiors in buildings and in particular for offices is made available, which initially enables flexible room division. The individual partition walls can not only be aligned along the direction given by the rail, but can in principle also assume inclined positions with respect to the rail. Because the partition is connected to the running shoe so that it can rotate around the largely vertical axis. In this respect, individual partition walls cannot necessarily be used as room dividers, but for example as a presentation board or the like. So it is conceivable to work with a metallic coating of the partition wall or a magnetic coating in order to be able to releasably attach photos, papers, etc. to the surface.

All of this succeeds additionally and advantageously in such a way that the partition wall used at this point also significantly improves the room acoustics. The fact that a noise protection filling is provided inside the partition wall and, under certain circumstances, the coating on the visible side of the partition wall is additionally designed to be sound-absorbing, for example as a fleece layer, contributes to this in particular. Of course, other coatings are also conceivable in this context, such as woven, knitted fabrics, carpeting, etc. or comparable textile fabrics, which not only provide the desired noise insulation, but also set visual accents.

All of this succeeds taking into account a simple and, in particular, weight-optimized structure of the partition in question. Because through the lightweight construction with the wooden frame and the foam filling as well as the coating on the visible sides, the weight per unit area of the partition walls can be reduced to values of, for example, 5 kg / m ² or even less. In addition, the material thickness of the partition is designed to be small, for example a material thickness of 50 mm and less.

As a result, the handling of the partition walls and their guidance and displacement along the rail is particularly easy and possible without great effort, and can consequently also be done by female staff in offices without any difficulty. In addition, the low material thickness limits any loss of space due to the erection of the partition walls to a minimum, so that overall acceptance is increased as a result. At the same time, an enormous improvement in room acoustics is observed, because every partition wall acts like a sound absorber, which is particularly beneficial in open-plan offices. This effect of the partition walls is also observed when they are set up freely in the room and are not used for room segmentation. This is where the main advantages can be seen.

In the following the invention is explained in more detail with reference to a drawing showing only one embodiment; show it:

• Fig. 1 the partition wall system according to the invention in an office room in perspective,
• Fig. 2 a front view of the partition system and
• Figures 3A and 3B Details of the partition system in the area of the running shoe in front view ( Figure 3A ) and side view ( Figure 3B ).

In the figures, a partition wall system for interiors in buildings is shown. According to the embodiment in the Fig. 1 The room equipped with the partition wall system is an office room. The partition system has at least one ceiling-side rail 1. According to the exemplary embodiment in FIG Fig. 1 the ceiling-side rail 1 is suspended opposite a building ceiling and connected to it, so that a gap S remains between the rail 1 and the building ceiling. In principle, however, it is also possible for the rail 1 on the ceiling side to be connected directly to the building ceiling. However, this is not shown.

The rail 1 serves to guide one or more partition walls 2. For this purpose, the relevant partition wall 2 is connected at the head end to at least one running shoe 3 which is guided within the rail 1. On the basis of the exemplary embodiment, it can be seen that each partition 2 is coupled to an associated (single) running shoe 3. For this purpose, the running shoe 3 is connected to the partition 2 centrally and on the head side. The partition 2 also has at least one floor-side roller 4 on the base side. The exemplary embodiment shows that each partition 2 is equipped with two base-side rollers 4 or two base-side roller pairs 4, each as an extension of its associated longitudinal edge 5.

The rail 1 runs predominantly horizontally. The two opposite longitudinal edges 5 of the partition 2 are largely oriented vertically. This also applies to the respective axes of rotation of the rollers or roller pairs 4 on the bottom side, so that according to the invention the partition 2 can be rotated overall about a vertical axis 6. In fact, the partition 2 is connected to the running shoe 3 so as to be rotatable about the axis or axis of rotation 6 in question and which is for the most part vertically oriented. This makes the partition 2 practical take any desired inclination relative to the longitudinal extension of the rail 1, as is basically the case in the perspective view according to the Fig. 1 is shown. For this purpose, the axis of rotation 6 runs on or along a vertical plane of symmetry or an axis of symmetry dividing the partition 2.

As already mentioned, each partition 2 is equipped with a running shoe 3. The partition 2 is connected to the running shoe 3 centrally on the head side. That is, the running shoe 3 is predominantly located on the axis of symmetry T of the partition 2. As a result, the partition 2 can easily be rotated with respect to the axis or axis of rotation 6 and the various inclined positions compared to the elongated rail 1 can be assumed.

The running shoe 3 is in turn guided within the rail 1 with the aid of rollers 7. For this purpose, the rail 1 is designed as a U-shaped hollow profile. Usually two rollers 7 are connected to the running shoe 3. In fact, there is a front roller 7 and a rear roller 7, which are each connected to the running shoe 3 so as to be rotatable about a horizontal axis 8.

The running shoe 3 also has a pivot bearing 9, which is equipped and set up to engage a predominantly vertically extending bearing pin 10. The bearing pin 10 is connected to a fastening anchor 11 connected to the head side of the partition 2. That is, the partition 2 engages with the bearing pin 10 connected via the fastening anchor 11 into the pivot bearing 9 in the running shoe 3. Overall, this is possible because the rail 1 does not absorb any weight forces from the partition 2. Rather, the respective partition 2 is supported in terms of weight with respect to a floor of the room equipped in this way by the rollers 4 on the floor. In particular, based on the Figure 3B it can be seen that the fastening anchor 11 is U-shaped in cross section. In fact, the bearing pin 10 is connected to the fastening anchor 11 in the region of a U-base. The fastening anchor 11 is in turn connected to the partition wall 2.

The partition 2 is designed as a whole to be noise-insulating. For this purpose, the partition 2 has a frame 12, which is only indicated, which in the exemplary embodiment and not restrictively is made up of wooden strips. The frame 12 receives a noise protection filling 13 in its interior. The noise protection filling 13 can be a filling made of a foamed plastic such as Styropor®. In addition, the partition 2 also has a coating 14 on its respective visible side. According to the exemplary embodiment, this front-side coating 14 is shown in FIG Fig. 2 equipped with perforations 15. These perforations 15 are openings in the coating 14 which have a diameter of 5 mm and less and ensure that sound striking the coating 14 is guided into the interior of the frame 12 to the noise protection filling 13 and is absorbed or removed there. can be converted into heat.

The coating 14 can be a fleece layer and / or wood layer and / or plastic layer and / or metal layer in whole or in part, as already described in the introduction. The partition 2 is also equipped with U-profiles 16 each, which overlap the partition 2 on the foot and head sides. With the help of the U-profiles 16, on the one hand the fastening anchor 11 on the partition 2 and on the other hand the rollers 4 can be fixed, without the frame 12 made of the wooden strips or the wooden frame 12 being damaged during this process run away. That is to say, the U-profiles 16 at the foot and at the head ensure additional stabilization of the partition 2.

The partition 2 is also equipped with connecting means 17 on the longitudinal edge. That is to say, the connecting means 17 are provided on the respective longitudinal edge 5 of the partition 2, or connected to it. The connecting means 17 are releasable connecting means 17 which, for example, work magnetically. According to the exemplary embodiment, the connecting means 17 on the longitudinal edge are each designed as magnetic strips.

In this way, the individual partitions 2 can be as shown in FIG Fig. 2 Longitudinal edge 5 detachably join together at longitudinal edge 5 to form a closed wall. By resorting to the magnetic strips as connecting means 17 on the longitudinal edge, the partition walls 2 can easily be detached from one another and, for example, brought into a rest position, as shown in the left part of FIG Fig. 2 is shown. In this rest position, the partition walls 2 are aligned along the transverse extent of the rail 1. In contrast, the one on the right corresponds to Fig. 2 illustrated working position of the partition walls to ensure that they are mainly oriented along the longitudinal extent of the rail 1 following the longitudinal edge side on the longitudinal edge side and are set up.
