This invention relates to an electricity installation sy¬ stem for hidden cable drawing, consisting of a cable duct with cable compartments placed horizontally to each other, and where the cable duct is provided with outlets for soc- kets and the like.

Such a system with a cable duct is for instance known from DK public examine application no. 150,871. The known duct has a rectangular cross-section with two horizontal and two vertical walls, where the upper horizontal wall and a ver¬ tical front wall form a moveable part, so that the cable trays mounted therein become accessible. In the cable duct there are cable trays resting on one of the horizontal walls.

The known cable duct must necessarily be assembled in one operation, which has the result that in connection with in¬ stallation in new buildings it may be damaged during other artisans' work. Furthermore the known cable duct has cer- tain requirements as regards positioning, as accessibility to the electric equipment presupposes that the moveable part can be swung into a vertical position.

The purpose of this invention is therefore to introduce an electricity installation system with a cable duct where assembly can be adapted to various phases of new buildings, and which is furthermore flexible as regards mounting and positioning possibilities.

This purpose is fulfilled in the way that the horizontal

compartments are fixed to a mounting fitting composed of a box with a bottom and two side parts at right angles to the bottom, as the mounting fitting is fixed to a gallows, and where a front frame and a back frame can be fixed to the side parts of the box.

By designing the cable duct in this way assembly of the cable duct may be carried out as a new building is complet¬ ed, as one e.g. begins with mounting the gallows on the wall and thereafter fixes the mounting fitting with corre¬ sponding front frame and back frame, whereafter the cable trays in the form of horizontal compartments are put in. The cables can now be laid into the horizontal compartments and be drawn to the outlets, which are installed in the front frame. When finishing the building the loose shelf is put on.

The front frame and the back frame function as support for the shelf, which at the same time closes the cable duct. By designing the front frame and the back frame in different heights, a further possibility of adapting the duct to va¬ rious room plannings is achieved.

The fixing of further mounting fittings to the gallows gives the advantage that it becomes even easier to fix other building equipment to the system, such as cupboards and the like. Radiators and pipes can be fixed to the ver¬ tical part of the gallows, which reduces bore holes in the walls.

The invention is explained in further detail with refer¬ ence to the drawing in which

fig. 1 shows the system according to the invention for electricity installation depicted partly as a cross- section, while

fig. 2 shows the same system in an interior decoration.

Fig. 1 shows a gallows 1, consisting of two parts at right angles to each other, where the first part for instance can be mounted on a wall, while the second part serves as the support for mounting fitting 3. In addition hereto further fittings 14 are placed in the area between the horizontal parts of the gallows, shown here in a C-shaped profile, for instance for mounting of cupboards. The mounting fitting 3 consists as shown in the figure of an open box with a bot¬ tom and two side parts at right angles to the bottom. Front frame 5 and back frame 4 are mounted on these side parts. Front frame 5 and back frame 4 may be of different heights. The method of fixing mounting fitting 3 to gallows 1 allows horizontal adjustment. The method of fixing front frame 5 and back frame 4 allows vertical adjustment. In the drawing a shelf 8 is put on top of front frame 5 and back frame 4, and this can easily be removed. In the space defined by mounting fitting 3, front frame 5, back frame 4, and shelf 8, cable compartments are laid in, which are placed next to each other horizontally. As is also shown in fig. 1, the system is intended for all types of cables, such as high or low voltage ones. Radiators 16 and heating pipes 17 are mounted onto the vertical part of gallows 1, thus reducing bore holes in the wall.

Fig. 2 shows the system according to the invention in an office environment with cupboards 15 mounted on the system, as well as cover 13 for hiding of radiator. Furthermore it shows outlet 7, e.g. sockets installed in the front frame 5, as well as the shelf 8, which is here used as storage space. Under the loose shelf cable compartment 6 is shown.
