Abstract

The channel has engagable front side releasable duct covers (11) comprising a self adhesive layer for attaching a skirting board to the duct covers. A protective film (12) covers the skirting board. An insulating material edge strip (13) is secured in an upper area and a bottom part of the duct covers that stick together with a permanent glue layer. Anchorage bars (16) are formed at a top face of a reason profile (10). A single cast-on hinge is engaged with the duct covers. An independent claim is also included for a method for installing a flush-mounted socket cable channel.

Description

The invention relates to a concealed base cable channel with an upper and a lower portion and to a method for installing this flush socket cable channel.

In the prior art, different techniques are used to supply residential and office space with electrical energy and communication lines. Often the electrical cables are laid under plaster, the cables are then invariably plastered. If changes are to be made later, for example, additional cables are drawn in, the plaster must be opened. Alternatively, the cables can be laid on the plaster or inside a cable duct attached to or in the wall. Such an example of the prior art show the 1 and 2 ,

Are known cable ducts that are laid in parapet height and run horizontally, so-called parapet ducts. If the cable ducts extend at the height of the floor, so-called base channels or baseboard channels are known for this purpose in the prior art. The present invention is based on such baseboard channels.

The disadvantage of the known installation by means of baseboard channels lies in the projection from the wall to the inside (at least 20 mm). This makes it impossible to place pieces of furniture directly against the wall. Other disadvantages are the greater effort to create connections to existing installations, and in the strong limitation of design options.

Examples of such baseboard channels can be found in German utility models DE 298 21 518 U1 and DE 298 21 519 U1 (Tehalit GmbH).

The invention has for its object to consume in a flush-mounted socket cable channel of the type mentioned and in the installation of electrical lines no space on the wall plaster, yet to allow easy changes to the electrical installation and finally no additional space compared to a flush installation with invariably plastered cables consume.

This object is achieved in a flush-mounted cable duct of the type mentioned in the present invention, that the cable channel has on its front a detachable manhole cover and that the manhole cover comprises means for securing a baseboard.

In this case, the cable duct can be laid in a first version directly on the unfinished floor and on the uncoated rough wall. In this case, it is advantageous if the flush-mounted cable duct according to the invention has at its front side in the lower region an insulating edge strip with which the screed is acoustically decoupled from the wall.

For a particularly simple fastening of the baseboard on the cable channel, the corresponding fastening means are formed according to a further embodiment of the invention as a permanent adhesive layer, which is covered with a protective film.

The intended when using the cable channel on the subfloor insulation edge strip is preferably attached only in the lower part of the lower portion of the front of the cable channel, in particular glued, so that the Dämmstreifen can be appropriately cut after the introduction of the screed over the top edge and no visible residues remain ,

Preferably, the manhole cover is latched or hinged.

Finally, the invention also relates to a method for installing the concealed socket cable duct according to claim 6.

In the following, several embodiments of the invention will be described in more detail with reference to drawings. Show it

1 a cross section through a wall and floor area with a surface-mounted channel according to the prior art,

2 a perspective view of the known surface-mounted channel after 1 .

3 a cross section through the wall and floor area with a flush-mounted channel according to the invention during assembly according to a first embodiment,

4 a representation accordingly 3 in ready assembled condition,

5 a representation accordingly 3 with a flush-mounted channel according to a second embodiment with a hinge on the cable duct cover and

6 a representation accordingly 5 but with a flush-mounted cable duct according to a third embodiment in the fully installed state.

In all drawings, like reference numerals have the same meaning and therefore may be explained only once.

The state of the art is in the 1 and 2 shown. A surface cleaning channel 1 according to the state of the art, as in 2 is shown in perspective, is in the edge region of wall 2 and soil 3 on the screed 4 and the plaster 5 appropriate. In 1 is also the usual impact sound insulation 6 between screed 4 and soil 3 as well as plaster 5 shown. In the usual way, the surface-mounted channel consists of a basic profile 7 , at the front of a manhole cover 8th is latched.

The 3 and 4 show a first embodiment of the flush-mounting base channel according to the invention, which is laid before the application of plaster and screed in the base area. Again, the cable channel consists of a basic profile 10 in which cable 9 can be laid, and a latchable manhole cover 11 , which at the top of a self-adhesive layer with a protective film 12 and at the bottom of a Dämmstreifen 13 which has an adhesive layer 14 partly at the front of the basic profile 10 is glued. The upper area of the insulating strip is not glued to the flush-mounted channel, so that after the introduction of the screed of the insulation strip along the dashed line in 3 can be cut off directly above the screed. The protruding Dämmstreifen is denoted by the reference numeral 15 designated.

At the top of the basic profile 10 are anchoring bars 16 molded, with which the flush-mounted channel can be anchored with advantage in the plaster.

To install the flush-mounted channel according to the invention this is placed before the application of the screed and the plaster between the wall and floor. Then plaster 5 and screed 4 applied. The protective film 12 can then be deducted and the protruding part 15 of the insulating strip 13 is cut off at the top of the screed. After applying the flooring 17 ( 4 ) becomes a skirting board 18 on the manhole cover 11 attached, for example by means of a self-adhesive layer on the manhole cover. The skirting board 18 Can then at any time together with the manhole cover 11 removed and re-assembled by snapping.

5 shows a second embodiment of the flush-mounted channel according to the invention, this time with a one-sided molded hinge 19 at the manhole cover 11 , which is also latched.

In all embodiments, the manhole cover itself can be used without skirting itself as a visible skirting.

If the finished floor with the screed is already present during renovation work, an arrangement for the cable duct as Unterputzeinbau accordingly 6 proposed according to the third embodiment. Here is another, narrower cable channel variant used. If the wall has already been plastered, a suitable slot is inserted in the base area and the cable duct plastered.

After inserting the cable ducts, the electrician will lay the cables in these base channels. The connection to the wall units can be made via cables laid under plaster or via commercially available flush-mounted cable ducts.

The most important advantages of the flush-mounting base channel according to the invention and its mounting are mentioned below. On flush socket channel according to the invention according to the first and second embodiments ( 3 to 5 ), which are intended for mounting on the subfloor, is a Sockeldämmstreifen 13 already installed so that the effort for the screed layer for attaching this Dämmstreifens deleted. The space in the cable channel according to the invention is substantially larger than in known surface-mounted channels, since the height of the screed is additionally available as a channel space. In all variants, the cables are easily accessible for changes in the electrical lines and additional cables, such as speaker cables, can easily be retrofitted in the channel. For wall and floor work, the baseboard can be easily removed and reinstalled without tools. If necessary cross-connections, for example in door areas, marketable, ie known flush-mounted cable channels are used as needed below the screed.

The particular advantages of the flush-mounting base channel according to the invention are on the one hand in the baseboard function, because the baseboards can be easily disassembled and attached again by means of the locking or folding system. Secondly, sub-paving is possible. Third, an integrated Dämmstreifen is provided so that the flush-mounting socket channel according to the invention can also be used on unfinished floors, without additional work to attach the Dämmstreifens would be necessary. Fourth, smaller devices can be accommodated in the channel, such as actuators for Instabus.
