Fittings for furniture construction

The invention relates to a kit for furniture elements, comprising a resting on the floor frame having at least one elongated support profile, which is detachably connected at least in a horizontal corner region of the frame having at least one surface element and / or at least one further Stüzprofil, wherein a along the Stüzprofil is designed to profile the outside open cable duct. In particular, in office furniture often is a desire to be able to create a limited number of standardized elements adapted to a variety of the respective special-purpose furniture elements. Moreover, there is often the need to carry cables electrical business equipment so that they do not hinder the work and do not disturb optically especially in office furniture.

In a prior art kit for furniture elements of the type mentioned above (DE-A 3019546), there is the frame itself only of vertical and horizontal support profiles to the formation of particular chair and table frames, in which surface elements such as table tops or chair seats are fastened. On the supporting profiles are produced as separate hollow profiles and secured by rivets to the elongate support profiles parallel cable channels. The profile for the outside open cable channels are completed by means of a cover profile made of soft plastic material. In the corner area which open at the end supporting profiles and cable channels are completed respectively by means of a channel angle connector. This design is intended to connect instead of the corner connecting either in horizontal or vertical direction more support profiles as Ansetzholme for horizontal or vertical extension of the frame.

The invention has for its object to provide a kit of the aforementioned type, which allows the creation of different, for cables having Direction furniture elements, without the need for cable ducts have to be installed as separate components.

This object is achieved in that for at least one supporting profile for creating furniture elements at an angle adjacent area elements designed as a corner connector is provided with at least two parallel to the profile longitudinal direction and to each other at an angle facing mounting surfaces for two to be interconnected surface elements that Befestingungsflächen each have a distance from the intersection line of the plane passing through the fixing surfaces levels and that between these layers and the adjoining the edges of the attachment surfaces accessible from the outside profile surface a to the profile longitudinal direction parallel mutzbarer as a cable duct cavity is formed. This erreichar is that regardless of the actual shape of the furniture component cable can be guided along the supporting profiles always, the cables must not be laid before the assembly of furniture elements, but also to create the furniture elements can be inserted into the cable ducts. If the mounting surfaces surface elements, so for example fixed wall parts of furniture elements is created between them and the lying between the mounting surfaces external profile surface a extending parallel to the profile longitudinal direction of the channel, can be inserted into the cable. If it is in the furniture element, for example, around a table, in which a rear wall and a side wall are connected by an inventive corner connector, so you can through the conduit formed between the rear wall, side wall and profile body the cable of which is arranged on the table top or above the table surface electrical appliances be performed without requiring your own cables channels would be necessary.

The mounting surfaces need not at an angle of 90 ° to be directed relative to each other, but may include a different angle from the right angle, which are suitable for the combination of several furniture elements together, in particular angle of 60 ° or 120 °.

Advantageously, the mounting surfaces are formed at projecting from the remaining profile body flanges at which the surface elements can be fixed for example by screws in a simple manner.

According to a further essential feature of the present invention, the profile body parallel to the profile longitudinal direction on at least a first duct having a circular internal cross-section and at least one second duct with a polygonal internal cross-section. The channels are used to receive the leg of support brackets for surface elements or devices, with the leg in its outer cross-section respectively correspond to the inner cross section of the channels. A carrying handle with only one leg, which has a circular outer cross-section, may for the pivotal mounting for example, a display monitor, a telephone set or the like used at a desk. Has the legs to conform to the second channel has a polygonal cross-section, the carrying handle is not rotatable relative to the Eckverbindungselementen. The channels may also be intended to accommodate foot portions of a furniture element, provided it is not resting on the wall portions alone.

In particular, for the creation of tables, it is advantageous if at least one supporting profile is formed by a cross member, with the example serving as a tabletop surface element about an axis parallel to the longitudinal axis traverse axis is pivotally connected. It is sufficient if the surface element only by a limited angle about the longitudinal axis is pivotable Travers. This allows, for example, to change the angle of the tabletop in adaptation to certain operating conditions, or the height of a person. Preferably, the cross member is formed from the central portion of a C-shaped bracket having vertically to the central section directed limbs, the supporting profiles formed in hollow sections are inserted. These support profiles may for example be made of Eckverbindungselementen above.

To the cross arm parallel to the longitudinal axis of the support rail can be arranged that is inclined relative to a plane perpendicular to the legs of the carrying handle plane and having slot-like perforations for receiving fastened to a surface element engaging elements. This allows independent of the concrete form of the Traverse a structurally simple and easy to install connection between the surface element and the crossbar, while nevertheless a certain mobility remains zwichen the surface element and the crossmember. The engaging elements may for example consist of an elastic material and having a shank portion and a relative to the width of the slot-like openings diameter larger in the support rail headboard. To produce the connection between the surface element and the crossmember, it is sufficient in this case to depress the engaging elements in the slot-like perforations.

According to another embodiment of the invention, the vorteilhalften crossmember has a circular external cross section, said cross-member partially engaging around clamps are fixed to the cross member connectable to the surface element at least. This embodiment is also dimensionally very easy to install and allows a larger pivoting angle of the surface element about the longitudinal axis of the crossbar. In both embodiments, the cable duct on the crossmember from a parallel to its longitudinal axis can be formed upwardly open profile strip which can be secured to the cross member or, for example, formed in one piece with the crossmember. Optionally, the support rail and the profile bar can be integral with one another, for example in the form of a bent sheet, which is fastened to the cross member formed of a simple hollow profile with a polygonal or round cross section.
