Space framework, especially for exhibition and interior construction

The innovation relates to a space framework, especially for exhibition and interior construction, consisting of hollow rods and knot pieces, which the Shape of a polyhedron or approximately a sphere or spherical cap as well as numerous concentric ones Have threaded bores for receiving screws for connecting the rods to the node pieces, wherein the space framework carries electric lamps and the electric cables for these lamps go through the hollow ones Knot pieces are performed.

Such a space framework is known from DE-OS 23 41 944. The hollow ones used in this construction Node pieces cannot be dismantled and also only have a relatively narrow cavity, so that the Passing the electrical lines through these junction pieces, especially in large numbers, is difficult or impossible at all. This is especially true in the event that the node in question has several carries electric lamps with appropriate leads.

The object of the innovation is to provide hollow knot pieces that can be easily dismantled for the above purposes create that avoid the disadvantages mentioned "

..! According to the innovation, this task is solved by ρ that in the cavity of the node pieces provided with at least one removable part, an electrical distributor piece is installed, which with the in the node piece

leading electrical lines is connected * This Knot pieces are made in such dimensions / that a sufficiently larger cavity for the accommodation of the electrical distributor is available. The detachable part of the knot becomes conveniently simple

connected to the other part of the node by screws. -i

After loosening these screws, the junction piece can simply be | dismantled so that the electrical distributor to the *

Connection or disconnection of electrical conductors exposed and good «E is accessible. f

S The innovation is particularly beneficial where 1 the node pieces carry one or more electric lamps. Then you can Lampej? in different ^ Execution are arranged at the relevant node, with their electrical connection to the network simply takes place via the electrical distributor in the relevant node.

The invention will then be explained with reference to the drawings of exemplary embodiments. Show it:

Figure 1 shows a node according to the innovation in the open state with two connected Rods that represent parts of a space framework;

Figure 2 is a further view of a node according to the innovation, which the electrical Contains manifold and carries an electric lamp;

FIG. 3 shows a view similar to FIG. 2 with a g

other design of the electric lamp and

Figure 4 is a view of a node according to the innovation, which several electric lamps

carries that on the electrical distributor are connected.

The hollow node (10) shown in Figure 1 consists of two parts (11 and 12), which in the exemplary embodiment through four screws (13) can be connected to each other. These screws (13) are through holes (14) in the part

(11) pushed through and in threaded holes (15) in the part

(12) screwed in. The two parts (11 and 12) dss

The knot piece (10) are provided with concentric threaded bores (16) for receiving screws, not shown serve to connect the hollow rods (17) of the space framework in question to the junction piece (10). the Terminal screws are arranged in the ends of the rods (17) and can be screwed into the Tapped holes (16) are screwed in. The connection screws are provided with through-holes, so that electrical lines (19) fed in the hollow rods (17) into the cavity of the junction piece (10) introduced and can be connected with their ends to an electrical distributor piece (20) which is in the Example of Figure 1 is installed in the node part (12). The electrical distributor (20) is known Execution and with numerous screws for fastening the bare conductor ends in the appropriate Insertion openings provided.

In the exemplary embodiment according to FIG. 2, the electrical distributor piece (20) is in part (11 A) of the hollow node piece (10 A) installed. The other part (12 A) of the junction piece (10 A) is here made of translucent material, and with (21) an electric lamp is indicated, which has a corresponding conductor on the electrical distributor (20) is connected.

The embodiment of Figure 3 corresponds essentially to that of Figure 2 and the same parts

therefore marked with the same reference numbers. The Knöfcenstück (10 B) consists äuä two parts (11 B and 12 B) züöaitlrtien which are connected together by bolts / similar v / ie when Aüsführungsbeispiel of FIG. 1 The cylindrical part (12 B) can therefore be removed in order to make the electrical distributor piece (20) in the node part (11 B) accessible, and the same also applies to the part (12 A) of the node piece (10 A) in FIG.

FIG. 4 shows an exemplary embodiment which corresponds to that according to FIG. 1, but on the parts (11 and 12) the junction piece (10) screwed electric lamps (22) using the threaded holes (16), that are electrically connected to the distributor (20) *

In the exemplary embodiment according to FIG. 1, the electric lamps can be connected to the Rods (17) be attached, which contain busbars can, with which the adapter can be brought into electrical connection (not shown).

Claims (2)

Protection claims 1. Space framework, especially for the exhibition and Interior construction, consisting of hollow rods and knot pieces that have the shape of a polyhedron or approximated to a ball or spherical cap and numerous concentric threaded holes for receiving of screws for connecting the rods to the node pieces, the space framework carries electric lamps and the electrical cables for these lamps through the hollow Knot pieces are guided, characterized in that in the cavity with at least one removable Part (11 or 12) provided node pieces (10) electrical distributor (20) is installed, which mi-c is connected to the electrical lines (19) leading into the junction piece (10). 2. space framework according to claim 1, characterized in that. the electrical distributor (20) in Node pieces (10) is arranged in known Way one or more electric lamps (21; 22) carry.
