Fittings for furniture construction.

The invention relates to a kit for furniture elements. 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.

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.

This object is achieved in that the kit comprises at least one elongate support profile, which is connectable to at least one surface element and / or at least one further support profile, one is designed to profile the outside open cable duct along the support profile. This is taken care of, that regardless of the actual shape of the leads can be, the cable must not be laid before the assembly of furniture elements, but also to create the furniture elements can be inserted into the cable ducts.

To create furniture elements at an angle adjacent surface elements, the invention proposes that at least one supporting profile is designed as a corner connecting member having 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 a distance of have the intersection of the plane passing through the fixing surfaces and planes that between these layers and the adjoining the edges of the attachment surfaces accessible from the outside profile surface a parallel to the profile longitudinal direction of cavity is formed. 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 l20 °.

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.

Further features and advantages of the invention emerge from the subclaims and the following description, the innovation described in connection with the accompanying drawings with reference to embodiments.

The kit shown in Fig. L to create a desk comprises two side walls l0, a rear wall l2, two generally at l4 designated corner connection elements for connecting the side walls l0 with the rear wall l2, a L4 in the corner connecting insertable C-shaped carrying handle l6 and l8 to this auflegbare tabletop. At the lower edge of the side walls l0 feet 20 are arranged, on which the table rests assembled, while the corner connecting l4 and the rear wall l2 at a distance from the bottom, respectively.

In the following, the corner connecting element l4 will be described in detail with reference to FIG. 3. Of the Eckverbinddungselement l4 forming profile body consists essentially of two equal surrounded by thick walls axially parallel channels 22 and 24, each of which has the first has a substantially circular cross-section and the second a rectangular cross section. Connected to the channel walls of webs 26 are two perpendicular directed mounting flanges 28 and 30, the wall for fixing a side wall l0 or l2 return serve. For this purpose, the attachment flanges 28 and 30 each have bores 32 and 34, respectively, can pass through the bolts 36 for fastening the side wall or the rear wall l2 l0. To the bolts 36 to pass and turn through the holes 34, 22 holes 38 are provided in the holes 34 diametrically opposite wall of the channel, which allow the insertion of a screwdriver or an Allen wrench, for example.

The mounting flanges 28 and 30 end at a distance from the cutting edge 40 of the plane passing through their attachment surfaces 42 and 44, planes 46 and 48. In this way, by screwing the side wall l0 and the rear wall l2 of the mounting flanges 28 and 30 between the inner surfaces of the side wall l0 and the rear wall l2 one hand, and of their facing outer wall of the profile body, which is formed by two webs 26 and located between them partially cylindrical boundary wall 50 of the first channel 22, on the other hand, a cavity 52 or, for example, as a cable duct for on above the table surface l8 disposed electrical devices can be used. The insertion of the cable into the cable channel 52 will thereby make easy, that the side wall and the rear wall l0 l2 at the corner of the table does not abut, but leave a gap 54 free.

The channel 22 serves for example for receiving a circular cross section having leg 56 of a carrying handle 58, the free supporting arm 60, for example, a data display device 62 carries, which is pivotally supported about the channel axis 64 to the table in this way (FIG. 5).

The second channel 24 of the corner connecting element l4 is preferably used in each case for receiving a short leg 66 of the C-shaped carrying handle l6, the middle section 70 forms a cross-member for supporting the table plate l8. The height adjustment of the carrying handle l6 in the channels 24 of the corner connecting can l4 take place in various ways, which are known per se, for example by locking pins which pass through holes in the Eckverbindungselementen and the short legs 66 of the carrying handle l6, or by suitable clamping elements.

At the Traverse 70 a support bar 72 is arranged with Z-profile-shaped cross-section for securing the top l8, eg welded. The support bar 72 has an upper l2 sloping from the rear wall to the front side of the table toward leg 74 with openings 76 into which on the underside of the table plate l8 is arranged, consisting of an elastic material such as rubber buttons 78 can be suspended. The tabletop l8 has at their side edges on notched flanges 80, which are intended to rest on pin 68 which can be plugged into different high-side holes 82 in the side walls l0. In this way the tabletop can be l8 changed in its inclination.

The lower part of the support bar 72 is formed as a channel-shaped horizontal cable duct 84, in the arranged through a gap 86 between the rear wall l2 and the tabletop l8 cord for on or above the tabletop l8 electrical equipment can be inserted.

Fig. 4 shows a simplified form of a corner connecting element 88 with a central portion 90, 92 and 94 having flanges 96 and 98 projecting at right angles at the ends of attachment surfaces. The central portion 90 of the corner connecting 88 has only rectangular ducts 90, which serve to receive plug elements, such as legs of carrying handles with reckteckigem section.

In Fig. L with l00 in the respective channels 22 insertable foot elements referred to, which are indicated by a dotted line, and then can be used when the furniture element not resting, as in the illustrated case, to its side walls and on associated with these feet.

In the embodiment shown in Fig. 6 of the C-shaped bracket comprises carrying in turn l6 leg 66 which can be inserted into the channels 24 of the corner connecting l4. The central portion of the C-shaped bracket forming l6 Traverse l02 is formed, however, by a simple, circular cross-section possessing pipe. At the Traverse a bent from a sheet metal cable duct or a cable receiving channel is l04 secured, for example welded.

The specific for connection to the Traverse l02 tabletop l8 has on its underside U-shaped clamps l06 which they are placed across the traverse, so that the table top l8 about the longitudinal axis of the cross member l02 is pivoted. In Fig. 7, the connection of a clamp l06 with the tabletop l8 on the one hand and the cross member l02 shown other hand closer.

The clamp l06 secured to the tabletop l8 by two screws L08 (only one of which is shown) which ll0 enforce the clamp legs parallel to the longitudinal direction and each engage in a radial threaded bore of a bolt ll2, the ll4 in a hole in the table plate l8 is used. The coil L08 may be actuated by a tool from the free end of the clamp legs ll0 ago.

The clamp legs ll0 each have a bore ll6 on (Fig. 6), by the after putting the clamps on the traverse l02 a safety pin is GL8 plugged, which prevents the lifting of the tabletop l8 of the Traverse l02, their pivoting to the longitudinal axis of the contrast Traverse l02 not hindered. The locking pins GL8 each have a locking tab l20, the GL8 prevents accidental falling out of the pins from the clamps l06.

The l04 the cable channel forming plate may be provided at its at the Traverse l02 subsequent section indicated by dashed lines perforations l22 which the truss axis l06 allow the passage of the clamps when pivoting the tabletop l8. Optionally, however, can also be the conduit l04 consist of individual sections, which are each longitudinally of Traverse l02 between the clamps l06.
