A gap between adjacent partition elements 4 is preferably not larger than 5 mm. Each of the partition wall elements 4 is assigned two guide sections 31 which extend into the partition wall element 4 in order to guide the partition wall element 4 slidingly relative to the holding device 3.

The cross section through a partition wall element 4 of a partition wall device 1 according to the invention according to the first exemplary embodiment of the invention is shown in FIG. There it can be seen that the holding device 3 comprises two parallel and symmetrically arranged profile frame 30 with C-shaped cross sections, between which the partition wall elements 4 are arranged. The profile frames 30 are connected via guide portions 31 which are in engagement with the partition wall elements 4, so that the profile frame 30 and two guide portions 31 each enclosing a partition wall elements 4 fully, wherein the partition wall elements 4 protrude in their extension direction on both sides of the holding device 3.

The two guide sections 31 extend symmetrically centrally through the longitudinal edge sides into a partition wall element 4.

Each of the guide sections 31 has a substantially T-shaped cross-sectional profile. In this case, a single-walled portion 31 b extends from a single-walled base 31 a of the guide portion 31 to a branch 31 c, at which a U-shaped

Section 31 d with two mutually parallel legs 32 connects.

On both sides of the base 31 a, hollow profiles 34 adjoin the base 31 a in order to have a slight extension on the outer sides of the partition wall element 4 and to overlap the partition wall element 4 at the edge.

By the guide portions 31, the partition wall element 4 is positively held on the holding device 3. By sliding pins of the partition wall element 4, which cooperate with the U-shaped sections 31 d of the guide sections 31, the partition wall element 4 is positioned against tilting and tilting with respect to the guide sections 31.

The partition wall element 4 comprises two different profile elements in the form of a base profile 40 and two cover profiles 43 which can be plugged into the base profile 40. Detent means 45 of the cover profiles 43 are latched in a form-locking manner with latching means 44 of the base profile 40.

Partition element 4 is acted upon by a biasing force which substantially corresponds to the weight of the partition wall element 4, so that the weight of the partition wall element 4 is compensated in its adjustment relative to the holding device 3. The partition wall element 4 shown in FIG. 2 has a depth T4 or a spacing of the outer sides of the cover profiles 43 of approximately 48 mm. The partition wall element 4 forms with the two guide sections 31 a single module of the partition wall device 1, whose depth T3 is about 50 mm and whose width B is about 200 mm.

To construct the partition wall device 1, the individual modules are joined to one another in the direction of the width B in such a way that the bases 31a of the guide sections 31 extend back to back. lie against each other. In the illustrated state, the cover profiles 43 can not be detached from the base profile 40, since the guide sections 31 surround the partition wall element 4 at the edge. Although a biasing device is shown in only one of the chambers 40b in FIG. 2, a plurality of preferably identical biasing devices may preferably be arranged symmetrically in both chambers 40b.

An embodiment with two biasing devices is shown, for example, in FIG. 4. This embodiment is substantially identical to the embodiment of FIG. 2, except that in this case both biasing means together produce a biasing force substantially equal to the weight of the partition member 4, so that the weight of the partition member 4 is compensated.

At and / or in at least one of the partition wall elements 4, a sound-damping and / or sound-absorbing material and / or a decorative element 47 may be arranged, wherein a decorative element 47 is shown for example in Fig. 3 on the outside of a cover 43.

Caps 46 are placed on the upper and lower ends of the base profile 40 and the cover profiles 43 to close the partition wall element 4 end. The cap 46 at the upper end of the base profile 40 forms a holder, preferably a shelf with a horizontal shelf for various small items.

Fig. 5 shows a perspective cross-sectional view through a partition wall element 4 of a partition wall device according to the invention according to the second embodiment of the invention.

This partition wall element 4 is almost identical to the partition wall element 4 according to the first embodiment of the invention, with the exception that a damping and / or locking element 48 between each leg 41 of the base profile 40 and one leg 32 of a guide portion 31 is arranged to the relative movement between the partition wall element 4 and the holding device 3 for damping and / or to lock the partition wall element 4 in at least one position relative to the holding device 3. The same reference numerals apply to the same features as in the first embodiment.

Fig. 6 shows a schematic view of a partition wall element 4 of a partition wall device 1 according to the invention according to the third embodiment of the invention for explaining the operating principle of the biasing device.

The pretensioning device in this case is a tackle device 5, comprising a pull cable 50, which is guided via a fixed roller 51, which is preferably fixed to the holding device 3 via a fixing 35, and a loose roller 52, which is coupled to a weight 53 is, wherein a first end 54 of the pull cable 50 is fixed to the partition wall element 4 and a second end 55 of the pull cable 50 to the holding device 3. The weight 53 has approximately twice the weight F of the partition wall element 4. In the left image, the partition element 4 is opposite the holding device 3 in a lowered position.

In the right image, the partition element 4 is opposite the holding device 3 in a raised position.

When transferring from the lowered to the raised position of the partition wall element 4, the partition wall element 4 moves upwards by the distance s against the direction of action of the weight F, while the weight 53 lowers by the distance s / 2 in the direction of action of the weight F. In a corresponding manner, the partition wall element 4 can now be transferred again from the raised to the lowered position.

In the raised and in the lowered position as well as in any intermediate position, the weight F of the partition wall element 4 is compensated by the biasing force of the tackle device 5. The pulley device 5 is preferably located completely in each position within the partition wall element 4 and is not visible from the outside.

Optionally, at least one of the partition wall elements 4 has at least one holder for holding objects on the partition wall element 4, wherein the holder is preferably detachably connected to the partition wall element 4.

The invention provides a modular, height-adjustable and sound-absorbing partition wall device 1, in particular for tables, preferably for office tables, which is available as a visual separation and with organization systems in various designs and colors.

Optionally, the partition wall elements 4 of the partition wall device 1 are horizontally or vertically adjustable. Due to the individual adjustability of the partition wall elements 4, the partition can be adapted to the needs of working at the table employee in terms of visibility and lighting conditions and / or acoustics.

This modular partition wall can be flexibly adjusted in the extending direction of the partition wall elements 4 and is expandable in pitch (e.g., 200 mm).

In addition, the partition wall elements 4 and their surfaces are acoustically effective executable and the partition elements 4 can be maintained in any position as needed and execution via a biasing device, which accomplishes a counterbalance. The biasing means may be mechanical and tribological (e.g., by frictional engagement). This can be done via a torque applied to gear 33 which meshes with a rack 42, or be realized with a cable 50 with fixed and loose rollers 51, 52 and with a counterweight 53. The cover elements or cover profiles 43 are preferably designed to be sound-permeable and have an area with up to 30% perforated portion, which pass the sound into an underlying porous absorber, preferably made of acoustic foam or polyester fiber boards. The sound is prevented inside the partition wall element 4 by a soundproof core or base profile 40 (for example aluminum) at the penetration of the overall structure and absorbed in the absorber.

The cover profiles 43 are optionally covered with a decorative element 47 made of textile, film, fleece and can be replaced if desired. As a result, if necessary, the color of the decorative element 47 can be changed and the replaced decorative element 47 can be recycled. However, it is also within the scope of the invention that the cover 43 itself is designed as a decorative element and, for example. Made of plastic, metal, glass, ceramic. The partition wall device 1 has a preferably porous absorber sound-absorbing or sound-absorbing properties. In addition, the partition wall device 1 prevents the transmission through the fixed partition wall and is thus also designed sound-insulating.
