1 is the framework for an inventive Table made of two longitudinal members 1 and two cross beams 2 as shown in FIG. 2 together, which on their Support the ends freely on columnar foot elements. In Fig. 1 is just the left end of the frame and just a foot element 3 reproduced with the parts exploded. The foot elements 3 are supported (in not shown Way) down on a runner 30 according to FIG. 3. Have along the cross beams 2 like the runners 30 preformed profiles, Reinforcements, recesses and / or openings for the precise positioning of the vertical connecting them Foot elements 3 to create a four-leg table, a C-shape table or T-shape tables.

The cross member 2 has two spaced apart in the Horizontal vertically projecting connecting pin 4, which axially insertable into the hollow profile channel of the longitudinal beam 1 are. Connecting the side members 1 to the cross member 2 can be done, for example, in that the hollow profile of the Side member 1 with a suitable fit on the connecting pin 4 is pressed on, so that a positive and non-positive connection arises. But it is also possible, if appropriate Dimensioning of the hollow profile channel cross-section of the side member 1 first heat up at its ends, then onto the Loosely push on the connecting pin 4 with the corresponding play and shrink with cooling so that a positive and non-positive connection arises. Also sticking the Side member 1 with a connecting pin 4 is instead or additionally possible. So is for the creation and the Obtaining a stable frame construction is neither an elaborate one Inadequate screwing still required.

To the tight fit of the side members 1 on the connecting pin 4 can still be improved, the connecting pin 4 at all or a part of the side surfaces a ribbing, teeth or Like. Have surface unevenness, such as a connector 10 to be discussed according to FIGS. 8a to 8b is illustrated in detail.

The longitudinal members 1 have, as can be seen clearly from FIGS. 6a, 6b, 7a, 7b and Fig. 10a can be seen on their side walls 6 outer surface profiling extending over the entire length of the profile 7, such as longitudinal ribs, engagement grooves or Intervention channels, for hooking in or clipping in longitudinally displaceable connecting, guiding, cladding and / or e.g. console or arm-like support elements 8.

The console-like support element 8 shown in FIG. 1 consists of a support arm 8 'and one at its free end attachable support arm 8 ''. The latter two parts are illustrated in Figs. 4a, 4b and 5 in more detail. from that it can be seen that one end of the support arm 8 'through corresponding webs 31 and the ribs 32 are formed that it fits appropriately anywhere, too laterally displaceable, on the profile structure of the side member 1 can be hung so that the support arm 8 'horizontally and the holding arm 8 '' is arranged vertically. After screwing of the support arm 8 '' with the free end of the support arm 8 'can, for example, rear walls, Screens, connection elements, attachment elements for the third level and the like are attached.

The support arm 8 'also has a projection on its underside 17, which, as can be seen from FIGS. 6a and 7a, the Snap the free end into place over the entire length of the frame extending cable channel trough 16 in the closed position serves. At the other end, the cable channel trough 16 is like this profiled that they in a rear (Fig. 6a and 6b) or front (Fig. 7a and 7b) engagement channel 9 of the side member 1 can be swiveled by means of an articulated bead can. The cable duct trough wall is in each case Neighboring the joint bead so that it is in their partially open position according to FIGS. 6b and 7b is locked in which the cables are inserted or removed can be completely without the cable tray 16 to lose weight. On the cable tray 16 can without or with holes or channels, spacers, Cable separations, strain reliefs, sockets and the like. Additional elements are screwed on.

The respective cross member 2, as can be seen from FIG. 1, with multiple holes for attaching other parts except the foot elements 3 equipped. So it is possible, for example, in Extension of the cross member 2 a console 33 for various Attach superstructures.

In particular, are in any angular position for the Chaining tables according to the invention on the cross members 2 Screw-on connectors 10, their special design 8a to 8c. Such a connector 10 has a connecting tab 11 for the cross member 2 and one Connecting pin 4, which is essentially the frame fixed arranged connecting pin 4 of the cross member 2 corresponds. The assignment of the connecting pin 12 to the connecting tab 11 is such that when the connecting tab 11 on the Cross member 2 is located, the connecting pin 12 at the same height lies like the frame-fixed connecting pin 4. So that worktop arranged on the chained further frame 19 the same height as that arranged on the first frame Worktop 19. One over such connectors 10 chained table can therefore be aligned with the first table be, but also form an angle with this. The Connection tab 11 has a longitudinal slot according to FIGS. 8a to 8b 34 to a corresponding longitudinal adjustment relative to to allow the cross member 2. At least two each other are opposite outer surfaces of the connecting pin 12 provided with a toothing 5, which the reliable Allows connection with a side member 1, here too Pressing, infiltration, shrinking and / or gluing is possible.

With angled or curved worktops 19 it is required to also bend the side members 1 accordingly. For this purpose, according to the invention, a joint piece 13 provided, of which a part in FIGS. 9a to 9c is shown, which has an identical second part can be combined into such a joint piece 13. The two parts of the joint piece 13 each have one Connecting tab 14, which over half the height of Partially reached. So two similar parts can be related a longitudinal axis L rotated relative to one another by 180 ° a hinge pin, not shown, to a hinge piece 13 are connected. On the joint, formed from the one above the other Connecting tabs 14 close after outside each a connecting pin 15, which with the connecting pin 4 fixed to the frame is identical, so that on both sides of the connection of the hollow profile of a side member 1 by means of pressing, infiltration, shrinking and / or Gluing can take place. The connecting pin 15 is there symmetrical to the contact surface of the connecting straps 14 arranged so that the side members connected on both sides 1 are at the same height. The height of the parts of the joint piece 13 is relative to the height of the connecting lug 11 a connector 10 according to FIGS. 8a to 8b dimensioned so that from a joint piece 15 and one or two connector (s) 10 also cross connections of variable angular position, however same height of the connecting pin 12, 15, are created can.

From Fig. 1 it can also be seen that by means of spacer rings 26 between the upper end of a foot element 3 and the Cross member 2 the worktop 21 at different heights, For example, the standard heights of 68 and 72 cm can be brought. The Fine adjustment of the height of the worktop 19 can be done in the lower end of the foot element 3 used more commonly Height adjustment elements are made.

The attachment of the worktop 19 on the frame made according to the invention by means of a quick-release fastener 18, which illustrates in more detail in FIGS. 10a to 11c is. The quick fastener 18 has a locking slide 20, which is longitudinally displaceable on a side member 1 can be clipped on. For this purpose the locking slide has 20 approximately U-profile shape, as shown in Fig. 11c seen. On the underside of the countertop 11 is over a pivot 23 a rotary latch 21 is attached. The Trunnion 23 can be engaged in an engaging hole at its lower end 22 of the side member 1 protrude. According to the number of Fastening points are therefore in the respective side member 1 corresponding engagement holes 22 are provided. The one on the Top of the locking slide 20 seated locking bolts 21 has the locking slide 20 laterally and in some areas below locking latch 36, which in a Locking position according to Fig. 10b the worktop 19 on the locking slide 20 (in Fig. 10a this is not shown), while at appropriate Adjustment of the rotary latch 21 via a handle 37 in 10b of the rotary latch 21, and thus also the worktop 19, from the locking slide 20, and so that the frame as a whole is released.

As can be seen in particular from FIGS. 11a and 11b, the Locking slide 20 in its upper transverse wall Longitudinal slot 24, which covers the engagement hole 22, and an inclined surface 25 on the top of its transverse wall. If the locking slide 20 on the side member 1 relative to the rotary latch 21, the axial position of the Trunnion 23 in the engagement hole 22 of the side member 1 is determined, is displaced on the side member 1, supports the locking bar 21 at different heights on the Locking slide 20 from. This can compensate for height the worktop 19 can also be done subsequently.

12 to 14b and 15 to 17b can between two Adjacent foot elements 3 outer and inner cable duct profiles 28 are clipped in due to their edge design. On the two vertical longitudinal edges are on top of each other opposite sides offset from each other 27 provided so that the intermediate profiled edge sections remain correspondingly flexible to 13 and 16 between two foot elements 3 easily can be clamped and removed again. The outer and inner cable duct profiles 28 according to FIGS. 12 to 17b are slightly convex on the outside, so that the vertical cable duct enclosed between them sufficient number of vertically running cables can record. As can be seen from Fig. 12, the Cable duct profiles 28 at the upper and lower ends or passage cutouts 38.

18a and 18b is a clamp-like plastic manufactured clip element 29 can be seen with the help of this a vertical cylindrical cable duct on a foot element 3 can be clipped on. This allows a variable Arrangement of such cable channels and is easy to use.
