Description

The The present invention relates to a partition wall element according to the preamble of claim 1 and in particular relates to such a partition element as privacy shield for dividing spaces such as Open-plan offices.

such Partition elements are well known and commonly included at least one partition body and a frame construction for receiving and holding the at least one partition body. Several partition elements can be combined or be connected, for example, in open-plan offices to divide smaller jobs. There are both autonomous or mobile partition elements with their own, preferably movable Stand device as well as fixed, on other pieces of furniture such as tables and chests of removable partition elements.

Around for example, in open-plan offices to the individual persons to ensure a trouble-free working environment to be able to exist in addition to that through the conventional Partition elements provided visual protection increasingly demand a reduction of noise-related disturbances.

In the DE 202 16 162 U1 The Applicant has therefore proposed a partition member in which the partition body is composed of at least one plate consisting essentially of a sound absorbing material. In a specific embodiment, the partition wall body of this known partition element consists of two outer panels made of wood soft fiber, cardboard or the like and an inner plate between the two outer panels, which is made of corrugated cardboard such that the corrugated cardboard is folded several times in itself in the direction of the length of the partition body.

Further, the DE 25 18 955 A1 a partition element consisting of two outer shells and a multi-layer mat between the two outer shells.

there The mat is made of an air-impermeable and flexible Material layer and at least one sound-absorbing material layer built up. The sound-absorbing material layer is preferably made of a material with a broadband high sound absorption capacity such as mineral fiber wool or loose felts of metal, Plastic or inorganic fibers.

The DE 26 50 886 C2 describes a sound absorbing panel comprising a pair of trim panels made of a thin metal perforated sheet and a core in the form of a honeycomb grid according to the principle of a Heimholtz resonator. In addition, the two cladding panels are covered with a layer of a porous, sound-absorbing material.

The first outer plate of the partition body in the form a micro perforated sheet offers an appealing design for the partition element while allowing the penetration of sound waves into the interior of the partition body. There are the sound waves low frequency (for example, in the range of about 500 Hz) within the sound absorber and the sound waves of higher frequency (for example, in Range of about 1,000 to 2,000 Hz) between the two outer plates absorbed. The partition wall element constructed according to the invention thus has both positive sound absorption properties as also positive design features with at the same time simple structure with few components and is advantageous for subdividing from, for example, open-plan offices.

In a preferred embodiment, the first nonwoven with the first outer panel, for example, by a hotmelt method bonded.

In a preferred embodiment of the invention, the second outer plate is also formed in the form of a micro-perforated sheet and between the sound absorption and the second outer plate of the partition body, a second web is arranged, which is preferably bonded to the second outer plate, for example by a hot melt process. In this structure, the sound absorption properties of the separation scored for its two sides.

In An embodiment of the invention includes the sound absorption device at least one sound absorption element of a certain size in the thickness direction of the partition body, the material thereof is preferably selected from mineral foam, mineral fibers, Nonwoven fabric, cardboard, foam, felt and the like. For example the sound absorption element is a cardboard with a honeycomb structure or a waveform, with the cavities of the cardboard connected to each other, or the material of the sound absorbing element is a melamine resin foam or a polyester wadding.

In a further embodiment of the invention includes the Sound absorption device (additionally or alternatively to the at least one sound absorbing element) a cavity a certain dimension in the thickness direction of the partition body.

In a still further embodiment of the invention, the partition wall element Furthermore, a standing device with or without roles on to a mobile, to form autonomously deployable partition element.

In an alternative embodiment of the invention, the partition wall element Further, a fastening device for mounting the partition wall element on a piece of furniture, such as a table, a dresser or the like.

Above and other features and advantages of the invention will become apparent from the following description of preferred, non-limiting Embodiments with reference to the accompanying drawings better understandable. Show:

1 a schematic perspective view of a partition element according to an embodiment of the invention;

2 a schematic perspective view of partition elements according to another embodiment of the invention;

3 a partial sectional view of a partition body of the partition element of 1 or 2 according to section III-III in 1 according to a preferred embodiment; and

4 a fragmentary perspective view of an outer panel of in 3 illustrated partition body.

1 shows as a first embodiment, a mobile partition element, which can be used for variable subdivision, for example, of open-plan offices. The partition element 10 consists essentially of a preferably rigid frame construction 12 - 16 , at least one partition body 18 and a standing device 20 , The frame construction 12 - 16 has two vertical clamping rails 12 on, between which the partition body 18 is held substantially vertically. Above and below is the partition body 18 through an upper cover profile 14 or a lower cover profile 16 covered.

The stand device 20 exists at the in 1 illustrated embodiment of two feet, fixed to the frame construction 12 - 16 are connected. However, the present invention is not limited to the stand apparatus shown here be. For example, only one or more than two feet may be used instead of the two feet 1 be provided; the feet can instead of at the outer edges of the frame construction 12 - 16 be arranged offset inside; and / or the base or the feet may be equipped with rollers to the displacement of the partition wall element 10 facilitate their mobility.

In the frame construction 12 - 16 is in the in 1 illustrated embodiment, a partition body 18 recorded and held. Alternatively, in the frame construction 12 - 16 also two or more partition body 18 be received, which clash.

The structure of the partition body 18 the partition wall element according to the invention 10 will be explained below by means of 3 and 4 described in detail.

Referring to 2 Now, a second embodiment of a partition element of the invention will be explained.

As in 2 by way of example, a workstation arrangement comprises a table 22 and two partition elements 10 , The table 22 basically has a tabletop 24 and two different legs in this embodiment 26 , Depending on the embodiment, the table 22 also with a table frame near the surrounding edges of the table top 24 or with a frame for carrying the tabletop 24 in which also the different legs 26 can be attached.

The two partition wall elements 10 are basically the same as the above based on 1 explained partition wall element 10 built up. The same components are therefore ver with the same reference numerals as in the first embodiment above see and their repeated description is omitted. Of course, but also arrangements with only one partition element 10 or more than two partition elements 10 possible.

The partition elements 10 in 2 differ from the partition element 10 of the first embodiment in that it does not have its own stand device 20 own, but by means of suitable fasteners (not shown), for example, on the vertical clamping rails 12 can preferably be fixed at any height, at the trailing edge of the table 22 , for example, directly on the table top 24 or on a table frame or frame construction, can be mounted.

It is therefore not autonomous, mobile partition elements 10 as in the first embodiment of 1 but to solid individual components. Of course, the partition wall elements 10 from 2 also on other pieces of furniture than at a table 22 be mounted, for example, on dressers and the like.

As in 2 indicated on the partition wall element 10 , in particular on its vertical clamping rails 12 , optional other components such as shelves 28 , Storage elements, electric rails and the like are attached. The same applies in an analogous way to the in 1 illustrated mobile partition wall element 10 ,

A description will now be given of the construction of the partition body 18 a partition wall element according to the invention 10 from 1 or 2 ,

As in the sectional view of 3 is the partition body 18 at its vertical outer edges (left side in 3 ) preferably formed with an outer profile, which is substantially the mating profile of the vertical clamping rails 12 corresponds to, so the partition body 18 firmly with the vertical clamping rails 12 the frame construction 12 - 16 can be connected.

To achieve the sound insulation function in addition to the usually intended visual protection function is the partition body 18 of the partition element 10 according to the invention of several layers 30 to 38 constructed as follows. Between a first outer panel 30 and a second outer panel 32 is a sound absorption device arranged in the embodiment of 3 essentially of a sound absorption element 28 is formed. The first outer panel 30 is formed as a micro-perforated plate, on the inside of a first web 34 For example, by means of a hotmelt process is glued. Preferably, but not necessarily, the second outer plate is also 32 formed in the form of a microhole sheet, on the inside of a second web 36 For example, by means of a hotmelt process is glued. Alternatively, the second outer panel 32 as in conventional partition elements simply formed from a plate of wood, metal or plastic and optionally provided with a decorative layer.

As in 4 As illustrated, the micro-perforated sheets are for the first and second outer plates 30 . 32 around a thin metal sheet, preferably steel sheet, with a thickness b of, for example, about 1 mm. The holes of the micro hole plate are formed and arranged in a preferred embodiment according to the standardization 1.1 / 2 RV. That is, the holes each have a diameter d of about 1.1 mm, and in a mutually offset arrangement (as opposed to a regular square arrangement) a distance w in the longitudinal and diagonal direction of the outer plate 30 . 32 of about 2 mm. Of course, the present invention is not on micro-perforated plates with the numerical values exemplified for the first and the second outer plate 30 . 32 limited.

The micro-perforated plate allows due to its perforation on the one hand penetration of sound waves in the interior of the partition body 18 the partition wall element according to the invention 10 It also has an attractive design, so that additional decorative layers on the outsides of the two formed as micro perforated plates outer plates 30 . 32 can be waived. In part, micro-perforated sheets are also found on the exterior walls of modern office furniture, resulting in a uniform appearance of the components in the open-plan office in this case.

For the first and the second fleece 34 . 36 Preferably, an acoustically effective web is used, so that the sound waves in the interior of the partition body 18 between the two outer plates 30 . 32 can penetrate between each with the fleece 34 . 36 coated outer panels 30 . 32 to be reflected back and forth while losing their energy. This construction is particularly effective for higher frequency sound absorption in the range of, for example, about 1,000 to 2,000 Hz.

That in the interior of the partition body 18 between the first and second outer plates 30 . 32 arranged sound absorption element 38 serves on the one hand to absorb sound waves of low frequencies of, for example, about 500 Hz and at the same time as a carrier for the two outer plates 30 . 32 , To improve the stability and rigidity of the overall construction is the central Sound absorption element 38 with the two outer plates 30 . 32 or the two fleeces 34 . 36 also glued.

The sound absorption element 38 of the partition body 18 is preferably made of a material selected from mineral foam, mineral fibers, nonwoven fabric, cardboard, foam, felt and the like. In one embodiment of the invention, the sound absorption element 38 a carton with a honeycomb structure or waveform. In order to increase the sound absorbing effect, the cavities of this cardboard may additionally be in the main propagation direction of the partition body with each other 18 be connected. In an alternative embodiment, the material of the sound absorbing element 38 of the partition body 18 a melamine resin foam or a polyester wadding. However, those skilled in the art of acoustics will readily consider other materials for the sound absorbing element 38 detect.

The total thickness of the partition body 18 the partition wall element according to the invention 10 is for example in the range of about 15 to 30 mm.

While in the above embodiments of the partition wall member 10 each a partition body 18 with only one sound absorption element 38 between the two outer plates 30 . 32 has been used, it is of course also possible in the context of the present invention, between the first and the second outer plate 30 . 32 several sound absorption elements 38 to arrange with the same or different materials and structures.

Further, the sound absorbing means of the partition body between the two outer plates 30 . 32 additionally or alternatively to the at least one sound absorption element 38 also contain at least one cavity. This cavity has analogous to the sound absorption element 38 a certain dimension in the thickness direction of the partition body 18 , In a specific embodiment, the sound absorption device of the partition body is 18 from several (identical or different) sound absorption elements 38 formed of the type described above, between each of which a cavity is provided. The partition body 18 with the at least one cavity also becomes stable between the vertical clamping rails 12 held the frame construction of the partition wall element.

Further, in the above embodiments, both were outer plates 30 . 32 of the partition body 18 the partition wall element according to the invention 10 formed in the shape of a micro hole plate and inside with a nonwoven 34 . 36 coated to a bilateral sound absorption effect of the partition wall element 10 to achieve. In the context of the present invention, it is also possible, however, only the first outer panel 30 form as a micro-perforated plate and on the inside with the first fleece 34 to coat and for the second outer panel 32 to use any other plate element.
