The present invention relates to partition panel system, intended to facilitate partitioning of restricted areas in larger premises, for example individual work areas in office landscapes.

Partition panels for the above stated purpose are previously known, comprising a supporting outer frame assembly, preferably manufactured from metal sections, arranged to support a flat sheet wall panel, painted in desired colour,, or covered by a suitable material. In order to maintain a vertical direction of extension in relation to a floor surface, the lower end portions of the vertically extending supporting sections are, for example, arranged with transversely extending support members. Since it often is desirable to attach shelves or similar against the partition panels, the vertically extending supporting sections are usually arranged with equally spaced apertures, which can be used to engage supporting brackets attached to the shelves or any other elements to be supported by the partition panel.

The above disclosed previously known type of partition panels are made with a certain panel height when manufactured, which can not be altered by a user. The possibility of attaching shelves, tops, cabinets and similar is based on the fact that such elements have a width extension substantially corresponding to the distance between the vertically extending supporting sections, since the supporting brackets utilized otherwise can not engage existing holes or apertures. Furthermore, the holes or apertures utilized for engagement with such supporting brackets are from estethical point of view undesirable, and a nonperforated smooth outer surface would obviously be preferred. By covering such partition panels with a textile material,.a certain sound absorbing effect is achieved, but since the textile material is applied directly against included flat sheet panel, the effect is small. It is further difficult to create a partition panel having a varied surface, e.g. with different materials or colours included in one specific partition panel.

The object of the present invention is to disclose a partition panel system, which removes all the above stated disadvantages related to previously known types of partition panels, and which facilitates simple

and rapid erection, simple attachment of shelves, tops, cabinets and similar, having any desired extension in relation to the width of the partition panel. Included partition panels have good sound absorbing properties, and can also be varied in a most attractive fashion with regard to colour and shape. Furthermore, included supporting sections are completely without the perforations or holes previously utilized to facilitate attachment of furniture elements. The partition panel system according to the present invention is further extremely well suited for erection of reception desks or other specific and individually adapted work positions, and also facilitate further advantages, as disclosed in the following descriptive specification*.

The partition panel system according to the present invention includes at least two from each other spaced longitudinally extending supporting sections, at a first end portion being arranged with a supporting member, intended to take up contact with a floor surface and to maintain the supporting sections in a substantially vertical direction of extension, and it is mainly characterised in that each other adjacently located supporting sections are arranged internally- joined by means of at least one frameshaped member, formed by an upper and a lower attachment member and two side members, said frameshaped member being arranged to support one or a number of plate-shaped members and/or to be surrounded by means of a layer, thus forming a wall surface unit, at least one of the attachment members being arranged with a longitudinally extending groove, substantially centrally located at an outer restricting surface.

With reference to Figs. 1 and 2, examples are shown relating to how a

partition panel system according to the present invention can be used in practice. Shown embodiments of partition panels include vertically extending supporting sections 1, 1 ^' , 1", having the lower end portions arranged with transversely extending supporting members 2, 2 ^' , 2", which are in contact with a floor surface. The supporting sections 1, 1 ^' , 1" are utilized for attachment of intermediately located units 3, 3 ^' , 3", located above each other and forming a wall surface, which is also shown in Fig. 3, where three such units 3, 3', 3" are located above each other between each supporting section 1, 1 ^" , 1".

The units 3, 3 ^' , 3" utilized to form a wall surface are more fully described with reference to the example of an embodiment shown in Figs. 4 and 5. This example shows that each unit 3, 3 ^' , 3" includes a centrally located plate-shaped member 4, located in grooves taken up both in an upper and a lower attachment member, 5 and 5 ^' respectively, but also in two side members, 6 and 6 ^' respectively. The upper and the lower attachment members 5, 5 ^* are arranged with a substantially semi-circular cross-sectional configuration, and having the convex surfaces directed away from the plate-shaped member 4. A centrally located longitudinally extending groove 7, 7 ^' is taken up in said convex surfaces, against which two strips, 8 and 8 ^' respectively, can be attached, e.g. by means of nails, screws or similar. The grooves 7, T are arranged' with a depth, and preferably also a width, exceeding the ■cross-sectional dimensions of the strips 8, 8 ^' .

A cross-sectional view of a complete unit 3, 3 ^' , 3" is shown in Fig. 6, but the strips 6, 6 ^' have not been shown. Said complete unit includes, apart from previously described elements, also a filling member 9, 9 ^' at each side of the centrally located plate-shaped member 4, and an outer layer 10 surrounding the unit, preferably being a textile material. The filling members 9, 9 ^' comprises advantageously of mineral wool panels, but also other materials can obviously be used, such as various types of rubber and plastic materials, as well as other materials having suitable properties. In order to facilitate required stretching of the enclosing layer 10 of cloth or similar, same is stretched by attachment of previously mentioned strips 8, 8 ^' against the bottom parts of the grooves 7, 7 ^' (not shown).

Said grooves 7, 7 ^' are also utlized for attachment of shelves, tops, cabinets or other pieces of furniture against a partition panel according to the invention. An example of how such attachment is carried out will now be more fully described with reference to Figs. 7 and 8, which intend to disclose attachment of a shelf 11. For this purpose, supporting brackets are used, formed by a first strip-shaped member 12, which by means of a bent over portion engages adjacent side portion of a groove 7. The strip-shaped member is preferably arranged having an extension substantially corresponding to the convex shape of the upper portion of the unit 3 against which attachment is to be performed, and it is transformed into a part 13 directed away from said unit 3, arranged to facilitate attachment against the shelf 11. It is obvious, that the supporting brackets can be located at any desired locations along the entire longitudinal length of each unit 3, 3 ^' , 3", and that thus shelves or other pieces of furniture, having a considerably shorter extension than the units 3, 3 ^' , 3", can be attached. Attachment of very long pices of furniture can obviously also be performed, by using required number of supporting brackets, and by attaching same against a number of units 3-, 3 ^' , 3", located subsequently following each other at a partition panel erected according to the invention.

The units 3, 3 ^' , 3" utilized to erect partition panel sections are further advantageously arranged having independently different heights, e.g. with the lowermost unit having a height adapted for attachment of a writing top or similar at desk height, and with subsequently following joints in direction upwards utilized for attachment of, for example, shelves. The uppermost unit 3, 3 ^' , 3" can be utilized to support a top forming a desk surface extending in both directions from said unit 3, 3 ^' , 3", e.g. a reception desk as shown in Fig. 2.

With regard to described embodiments, the upper and lower attachment member 5, 5 ^' are shown having a solid cross-section, e.g. manufactured from wood, but also a non-solid cross-section can obviously be used. An example of this is shown in Fig. 10, and may advantageously be manufactured from a synthetic plastics material. The strip 8 used to hold and stretch the cloth forming a surrounding layer 10 can be attached without use of screws, nails or similar, by arranging the groove 7 with engagement means protruding from the side surfaces, which

engage and hold the strip 8 in a position inserted into the groove 7.

Furthermore, partition panels including glazed sections can also be accomplished, in which case the plateshaped member 4 is replaced by a sheet of plate glass 14, as shown in Fig. 9. In this case, the surrounding layer 10 of cloth or similar is obviously not used, nor any fill ng elements 9, 9 ^' . The latter elements 9, 9 ^' may also for certain applications advantageously be excluded from embodiments including a surrounding layer 10 of cloth or similar.

The method for attaching the units 3, 3 ^" , 3" against the vertically extending supporting sections 1, 1 ^' , 1" has previously not been discussed, nor the fashion in which said sections 1, 1 ^' , 1" can be designed. An example of such a supporting section 1, 1 ^" , 1" is shown in Fig. 11, intended to serve as an example of a section 1, 1 ^' , 1" arranged to be used as an intermediately located section between two elements of a partition panel. Said section includes two grooves 15, 15 ^' , having the open portions* restricted by means of two towards each other extending parts. The inside surfaces of these two restricting parts are utilized as contact surfaces for attachment means insertable into the grooves 15, 15 ^' , which are joined to the side members 6, 6 ^' , extending outwardly from same. An example of a supporting section 1, 1 ^' , 1", intended to serve as an outer section restricting the extension of a partition panel, is shown in Fig. 12, and with an example of an attachment means 16 indicated, arranged to hold a unit 3 against the section. The attachment means 16 may in its simpliest form comprise of a screw or a bolt, the head of which is used to obtain contact against the internal surfaces of the towards each other extending parts at the opening of the groove 15. In view of the large number of previously known means which facilitate attachment against grooves 15, 15 ^' of disclosed type, further examples are not considered as required.

The examples of supporting sections 1, 1 ^' , 1" disclosed above can obviously be further varied, and for example can the number of grooves 15, 15 ^' be further increased, e.g. to accomplish a T-shaped partition panel, three grooves 15, 15 ^' can be arranged, two in an opposed relationship and a third located in a rotated relationship to the other two grooves, in which case said rotated relationship obviously does not

need to be 90°. Furthermore, crosswise connection of partition panels can also be accomplished, in which case the number of grooves is increased to four.

The units 3, 3 ^' , 3" utilized for erecting a partition panel may further be arranged having a non-linear extension, in order to facilitate erection of curved partition panels, and this has been indicated in Fig. 2, in which the reception desk shown includes such curved units 3, 3 ^' , 3", which can be arranged having any desired selected angular extension for the curved sections.

The layer 10, previously mentioned as preferably being cloth or other textile material, can obviously also be other materials, and in this respect also rigid plate-shaped materials. By arranging the outer edge portions of the upper and the lower attachment members 5, 5 ^' , and also associated side members 6, 6 ^' , with a recess, and a rigid plate-shaped member may for example be attached abutting the recess, the depth of which preferably* is arranged to correspond with the thickness of the plate-shaped member. Alternatively, and for example, a metal sheet or similar, having bent over edge portions, can be directly attached against the towards each directed surfaces of the attachment members 5, 5 ^' and the side members 6, 6 ^' . It is thus possible to accomplish partition panel units having side surfaces of a substantially rigid material, such as sheet metal, synthetic plastics, wood or any other desi ed material .

It is also possible, for example as a lower section, to utilize a unit having one or a number of channels for electric or telecommunication wires, and with necessary apertures for attachment of connection means. Furthermore, a covering profile is advantageously arranged attachable against the upper groove 5, 5 ^' of a partition panel, having an outer convex surface matching the upper surface of the partition panel.

The partition panel system according to the present invention makes it possible to vary the appereance of a partition panel in a previously unknown way, both with regard to shape and colour, since it makes it possible to erect as desired a partition panel of units 3, 3 ^' , 3" having from each other different height and colour. Furthermore, rapid and

simple attachment of various pieces of furniture can be carried out, completely independent of the longitudinal length of same. The partition panel according to the present invention can thus be regarded as a system for building desired interior, and with possibility to meet all requirements relating to functional work positions. A partition panel according to the present invention can further be erected in a rapid and simple fashion, or demounted, and it may further be designed to meet a variety of requirements relating to sound absorbing properties.

The examples of embodiments of the present invention shown and described are only intended to serve as examples of embodiments within the scope of the inventive thought, and further modifications are thus possible within the scope of the following claims.
