In known devices of this type, each incandescent lamp a base or a fit, from which two mandrels of different lengths protrude, which in the Board are pressed in and thus in electrical contact with one of two different conductive foils to be brought.

It has been found that this arrangement is not satisfactory because the. electrical contact between the thorns and the conductive foils are always bad as soon as the Arrangement was used for a period of time. Heating and vibrations caused by the device during the Operation, lead to the fact that the Expand thorns drilled holes, which leads to the fact that loose contacts occur again and again.

Furthermore, up to now it has not been possible to create devices for moving according to the wishes of the individual users To realize luminous pictures with the most varied of surfaces and shapes, which carry out the most varied Allow luminous performances and one frequent Would allow modification and renewal while constantly reusing the same elements.

The device according to the innovation solves those described above Problems completely.

According to the innovation, the device comprises at least one panel consisting of a stack of conductive foils from one another separate insulating plates, means for electrical connection, .which electrically with each conductive foil

The device comprises at least one block or panel made up of a sandwich arrangement of insulating panels is formed i between which foils, wire mesh, Grids or other conductive elements 2, hereinafter

^ 09808/0603

"Films" called, are used. The number of plates and foils 2 is absolutely arbitrary and depends solely on the requirements. ·

The plates 1 consist of a semi-rigid easily pierceable and preferably impermeable and non-flammable insulating material, such as polystyrenes, foamed polyurethanes, formaphenols, etc. Pie foils 2 are advantageously made of aluminum, copper, brass or other metals or conductive alloys. These foils have a thickness as small as • is possible, e.g. of the order of a centimeter.

It is advantageous that the plates 1 and foils 2 are solid are connected to one another, "for example by gluing.

The outer surfaces of the panel produced are preferably covered with an outer skin 3 (Fig. 2), wherein this should have a decorative effect.

1 shows that semicylindrical recesses H are arranged starting from the narrow lateral sides of the plate 1 and that the foils 2 have corresponding collars 5. These recesses serve to hold sockets 6, which advantageously have a tab connected to the corresponding film 2 with a rivet 8, the connection also being able to be made by welding or by other means. The end of the socket can be flush with the narrow side of the plate 1 or

4Q9808 / 0503

preferably to be set back a bit. -

The Pig. 3 and 6 show that the sockets 6 are so interlocking of two or more multilayer panels A, B using conductive rods 9 that allow disappear completely in the sockets 6 when the panels A, B are joined together and brought into contact with one another. In the same way, a panel A can be connected to a power supply programming unit C as shown in the is described below.

Panels A, B are used to supply power to the power supply shown in Fig. illustrated glow sticks. These rods, which are designated in their entirety with D, comprise a conductive core 10, which at the bottom has a section of larger diameter 11, which is advantageously turned off as shown at 12 is. The larger diameter portion 11 is formed below, for example by die forging, that he ■ has the shape of a lance tip 13.

A conductive sheath IM, which surrounds the soul IO, is at least as large in diameter as the larger diameter portion 11, and has on her The lower end also has a section 15 in the form of a lance tip.

An insulating sheath 16, for example made of plastic material, surrounds the core 10 and the section of larger diameter 11, up to the lance tip 13. The wall thickness this envelope is chosen to be very thin, since its outer diameter is at most equal to the thickness of the lower section 15 the conductive sheath 14 should be. The envelope 16

409808/0503

leaves a gap 17 between it and the inner wall of the casing 1H , this casing extending only over part of the height of the core 10. The space between the sheath 16 and the sheath as well as the space between the core 10 and the sheath 14 is filled with adhesive l8, which forms an insulating layer and at the same time ensures the connection of the core 10 to the sheath 14 and any relative rotational movement between the two Elements prevented. The adhesive 18 also serves to fasten a washer 19 made of insulating material, which extends between an enlarged part 20 of the casing 14 and a tip 21 which extends the core 10 in the axial direction.

The washer 19 consists of an electrically insulating material and serves, if necessary, for reinforcement the locking between the core 10 and the casing 14, For this purpose, the washer can have a semi-flat ■ Have section, which against a likewise semi-flat Part of the tip 21 and / or the soul 10 acts. Likewise köameaa the mowing, the top 21 and the corresponding Wall 4 <he IlaifceaKlegsefaeifce 19 and the inner wall of the enlarged Part 20 asaT © should be tightened in order to prevent the adhesive 18 from sticking. facilitate. Any other mechanical means can also be used between the core 10 and the casing 14, which means that these two parts are relatively to each other ue & relat or somehow differently offset.

The outer wall of the enlarged part 20 is preferably polygonal or in some other way non-circular in shape,

4Q98ÖS / ÖS03

to the angular fixation of a cap 22 made of transparent and possibly colored material. The cap 22 is locked via at least one cam 23, which acts against a shoulder 24, which is below in the expanded Part 20 is formed. The cap 22 contains in its Inside an incandescent lamp 25, the filament 26 of which is supplied with power via two wires 27 and 28.

The wire 27 is through a lateral bore 29 of a fixed in the cap 22 and guided over a cam 31 of the same fixed core. The wire 28 is in similarly passed through a central bore 32 of the core and is passed around the base 30a of the core at 28a. A preferably elastic clamping ring 33 made of insulating material is used to hold the folded-over part 29a of the wire 27 against the inner wall of the enlarged part to press the sheath 14.

It can also be seen that the tip 21 formed by the core 10 engages in the central bore 32 and is thus pressed against the wire 28.

As can be seen from the foregoing, the core 10 and the larger diameter portion 11 are both outwardly towards and from the casing 14 with the exception of the lance tip 13 and is furthermore completely insulated the core IO is electrically connected to the wire 28 of the incandescent lamp 25, while the sheath 14 to the wire 27 this bulb is in electrical connection.

The sheath 14 always has the same length while

409808/0503

the section 11, which continues the soul 10, towards of the rod is of variable length, so that any film 2 can be reached and pierced during the The lance-shaped part 15 of the casing 14 only ever reaches the first film 2, as shown in FIGS. 5 », 5a is. · '

To put a stick in its place, this is done by one of the panels A, B or another - pushed until it comes into contact with the outer skin 3 on the panels.

Figure 5 shows that the pushing in results in successive perforation of the conductive foils, which is facilitated by the lance-shaped design of the parts 13 and. The perforation leads to flanging in each slide 2 on either side of the drilled hole.

After the rod has been pushed in completely, it is rotated 90 ° and then takes the position shown in FIG. 5a a. This rotation has the consequence that only a part of the sheaths 34 widened by the lance tips 13 and 15 and in this way a good electrical contact is made, which also arises from the fact that the other parts of the flanges 34 are not widened further, since over the lance tips 13 and 15 both the sheath 16, the the part 11 surrounds, as well as the casing 14 have a circular cross-section.

5 and 5a show that the electrical contact can be further perfected by providing a spring, for example an elastic washer 35 below the enlarged part 20, the washer having the effect

4O98Ö0 / ÖSÖ3

to lift the rod after it has been attached and rotated through 90 ° so that the lance-shaped sections and 15 are pressed more strongly against the flanges 34.

The panels A and B with the glow sticks will be electrically, for example as shown in Fig. 6, by a device C which shows that the two outer foils 2a, 2b via a common conductor 36 » which leads to a terminal 37 of a voltage source, always have the same potential. As a result, the sheaths 14 of all rods D are always on the same potential regardless of whether the bars are inserted from one side or the other of the panel will. As for the other foils 2, they are, for example, with the independent conductors 3 &, 38a, ..., 38η in connection, which in turn are connected, for example, to voltage regulators 39, 39a ... 39n, which are supplied with voltage via special switches 40, 40a ... 40n. The switches themselves are again with one Main voltage regulator 41 connected to that of another Terminal 37a of the source is supplied with voltage via a changeover switch 42. The changeover switch 42 allows the terminal 37a the source, when it is in the position shown, via a programmer 43 with lines 38, 38a ... 38n to connect.

By arranging the bars D according to different motifs and they choose so that they each cut the correct film 2, the most diverse light effects can be realize as the corresponding incandescent lamps as a function of various parameters depending on the manual

409808 / ÖSÖ3

Actuation of the switches ¹ JO and the voltage regulators 39, 39a ... 39n and 41 or can be controlled by the programmer kj> , the latter being for example an acoustically sensitive device.

Fig. 7 shows a somewhat different embodiment of the rods, which is characterized in that the section 1 surrounded by the insulating sheath 16 has a smaller diameter than the rear part 13 a of the lance tip 13. In this way, the rod rubs when the rod is inserted Sheath 16 not on the material of the plates 2 and foils 2, so that the insertion pressure to be applied when inserting the rod remains practically the same regardless of the length of the respective rod.

When using the spring 35, the limitation of the friction also leads to the fact that it fulfills its task more effectively, namely the lance-shaped parts against the flanges to keep the conductive foils 2., since now the friction between the envelope 16 and the fabric of the panels 1 can be neglected.

In the embodiment according to FIG. 8 is located above the lance-shaped part 13, a second part 13 ^ also in the shape of a lance tip. The same applies to part 15, above which a part 15 ^ is similar Shape is located. This arrangement is particularly advantageous when two bars are very close to one another can be inserted into the board. The first rod can bend the conductive through which it has pierced Foil 2 cause the electrical contact between

A098Ö8 / 0503

this slide and a second one in the immediate vicinity to the first inserted rod can be affected.

However, since there are two adjoining lance-shaped parts 13, 13 * on the one hand and 15, 15 ^ on the other hand, which are separated from one another by a narrow segment 44 with a circular cross-section, it is ensured that the electrical contact is either at the level of one or the other other of the two sections 13, ^ ₁ or 15, 15 _{χ is} made.
