Abstract

A building board (1) has at least one inwardly expanded groove (3) on its face which in the mounted state of the board faces the inside of a room, i.e. on its face opposite to the room-delimiting ceiling or wall. An outwardly invisible current conductor rail (5, 6) is arranged at each edge of the groove in such a way that it has at least one non-insulated longitudinal edge (5a, 6a) oriented towards the inside of the groove. Two double-pole sockets (10, 11) are arranged at the other surface of the board. One current conductor rail is connected to one pole of the socket and the other current conductor rail is connected to the other pole of the socket. These boards may be used for creating a suspended ceiling or walls of permanent rooms, as well as for creating exhibition stands for fairs in which there is a need for changing from time to time the arrangement of the light sources used.

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to panels for making suspended ceiling or forward walls, as well as for the construction of stalls.

Background Art

Different panels have already been designed and used for the construction of suspended ceilings or forward walls as well as for the construction of stands. Such panels can be manufactured and also used in various sizes and shapes, usually square. Suspended rails whose T-shaped cross-section is placed on the head very often are used for hanging panels as ceiling elements. The disadvantage of all known panels is that they are not very suitable for fixing electric lighting. Therefore, very often, under the soffits formed by panels, rails are mounted for the introduction of lighting, which is not only associated with additional work and corresponding costs, but also results in, more importantly, mostly rather disturbing than decorative effect. In addition, the rails need suspension devices and electrical connections, so that the ceiling panels can be damaged and additional changes are only possible with additional costs.

SUMMARY OF THE INVENTION

The elimination of all these drawbacks is now provided by the panel according to the invention, which is suitable not only as a panel for suspended ceiling but also as a structural element for a forward wall as well as a structural element for the construction of stands in exhibition halls.

BRIEF DESCRIPTION OF THE DRAWINGS The following is an example of an embodiment of a panel according to the invention and its use according to the accompanying drawings, which show in FIG. 1 a perspective view of an individual panel according to the invention, in FIG. cross section of panel groove, on. FIG. 3 is an enlarged scale view of the same groove with the current collector of the illumination in FIG. 4, while FIGS. 4 and 5 show two possibilities of how the suspended ceiling can be made of multiple panels, and FIG. 6 and FIG. 7 possible ceiling designs. EXAMPLES OF THE INVENTION

The panel 1 shown in FIG. 1 is expediently made of plastic with the following features: > 10 and 1 kg / dm3

> 70 ° C < 2 7. Specific resistance Specific weight Softening temperature Soak up

Hardly flammable, self-extinguishing.

Can be coated with a sawdust coating.

Three inwardly extending grooves 2, 2 and 11 are essential in the panel according to the invention, the number of which may of course be either larger or smaller. At each edge of the groove, an unnoticeable conductor rail and, optionally with a cross-section of at least 6 mm <'> are disposed on the outside, as can be seen from FIGS. directed towards the inside of the grooves. The conductor Z connects the conductor rail 5 to the supply rail 2. while the conductor S connects the conductor rail 6 to the rail 10, not shown in Fig. 1 but in Fig. 1, which is parallel to the rail 2. End these two feeder rails 2 and fs are each connected to one pole of each of the two JLL and 12th two-pole sockets.

Panels of this kind can now be used to construct suspended ceilings, as is known per se in conventional panels and as shown in Figures 4 and 5: Thus, Figure 4 shows how such panels lie on bars 12 with a T-shaped screen which is hinged on the ceiling by means of hinges or ropes 14. In the case where the T-shaped rails 12 are felt to be disturbing or otherwise ineffective in the room, bars or rods may also be used. ropes 10, which are fixed to the ceiling 1Z and which are each guided through one aperture 1a, of the panel 1, and at their lower end, for example, with a reinforcement, on which one cut-off underlay is always located in the groove 2, the diameter of which is larger than the diameter of the opening 1a. 4

Conveniently, a transformer is disposed on one of the panels, which serves to reduce the local mains voltage to a low voltage, for example 12 V, which can then be fed to one of the conductor rails 5 and 6 by means of one of the sockets 11 or 12. The second receptacle serves to connect the conductors of the first panel to the conductors of the adjacent panel, without necessarily requiring all the panels of one ceiling to be equipped with conductor rails. Of course, panels without grooves or panels with grooves without wire rails can also be used. As such a ceiling can appear in a completed mounted state, it is shown in Fig. 6 and Fig. 7.

The illuminator shown in FIG. 6 is provided with a connecting rod 12, which carries a lamp 20 at its lower end and has a pyramid-shaped end element 24 at its upper end, each having a current collector 21 on two opposite surfaces. optionally 22, each of which lies on the bare edge 5a, 6a, respectively, of the conductor rail 5, respectively &amp; ampere. The spring 23 serves to provide the contact pressure necessary for good current flow. To remove the illumination body from the groove, the adjacent panel may be lifted and the pyramid-shaped end element 24 may be extended from the groove. However, it is also possible to use the pyramid-shaped end element 24, if, as is customary, it does not have a rectangular but rectangular cross-section to press up slightly against the spring force, then rotate it 90 degrees and remove it downward.

Obviously, the panels according to the invention can be used not only for the production of suspended ceilings, but also for the production of forward walls, as well as for the construction of a stand at Civel, that is to say wherever emphasis is placed on the possibility of replaceably fixing the lighting fixtures.
