Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a wall surface having a plurality of passages consisting of wire passages accommodating electrical distribution conductors and at least one lateral passage accommodating other electrical conductors or tubing having a specific function. Regarding multi-purpose service ducts.

More specifically, the present invention is intended to be mounted on the surrounding wall of a factory, shop, or residence, and to house therein not only electrical conductors, usually electrical conductors, but also pipes and the like carrying fluids. It provides service ducts consisting of moldings.

Such wall service ducts are usually fixed to indoor walls like baseboards near the floor or under windows.
They are hidden by so-called clip-shaped covers that are structured so that the conductors, pipes, etc. to be protected can be easily removed.

A molding electrical service duct with trapezoidal side sections is shown in French Patent No. 2,097,279.

However, if you have conductors that are to be terminated at the location where the lateral conductor path is used for the branching device, you may need to provide both a specific power tap or outlet and a connection box or junction box on the face of the platform. It is necessary to provide an opening for the connection, or it is necessary to install the connecting cable through said opening.

This operation, of course, has the disadvantages of time and equipment required, but also has the disadvantage that it leaves an unsightly opening and provides insufficient protection for the conductor.

In the standardized method of branching equipment including this power outlet, a plug-in system is used for the array 1-let.

That is, the branching elements are connected to the conductors through openings provided at equal distances along the branching device.

In addition, this branching device may be used for other conductors that connect one point to another (e.g. telephone equipment connections, audio speaker connections, signal circuits, control circuits, alarm circuits or remote control circuits, etc.). It has one or more side passages or channels.

It is also safe to have the effect of branching the cable terminals at a junction box or a specific output outlet in the branching device.

There are difficulties in coupling the power branches of systems with plug-in outputs at regular intervals, as well as difficulties in exiting the cable ends of the side passages.

Furthermore, if side passages are provided on both sides of the power distribution passage, 1
It becomes impossible to pass conductors from one side passage to the other.

The present invention obviates these drawbacks and its primary objective is to provide a service duct assembly of practical and elegant construction, the cable exits of which are concealed.

Furthermore, it has a pre-provided invisible opening arrangement for the cables in the side passages, while aiming to prevent the ingress of dirt or foreign objects etc. into the inside of the duct.

The cable 31 is initially in the lower passage 30 but passes behind the plug-in part of the molding to the upper passage 20.

The terminal end 31a of the cable passes through the penetration 35, making a loop in the upper passage 20, passes again through the opening 21,
It passes through the upper wall 2 of the molding.

Thus, when the connector 32 is fixed with the hook 32a, the connecting portion of the cable 31 is completely covered.

Figure 3 shows an insulating cleat for placing a conductor inside the plug-in part for the molding 1, but it is not shown in detail because it is not the main part of the invention. It is.

The insulating cleat has a mortise 36 into which a plug (pin) is inserted, the location of which corresponds in cross section to the plug-in opening 8 of the molding.

It also includes a small vertical penetration 35 on the back side,
It forms a conductor path between the passage 30 and the passage 20 or vice versa.

FIG. 2 shows a simplified service duct, which simply includes a lower passage of molding and has a cover with a pedestal.

The general structure is the same as in the previous embodiments, and like parts are given the same reference numerals.

The molding 1 has a cover 6 which fits the hook opening 1 and the plug-in opening 8 through which the pin passes.

The bottom plate 14 of the molding 1 extends vertically downward,
The upper wall 2 forms a fixing ridge 4 for fixing the cover 6 and an upper decorative edge 37.

The lower wall 3 of the molding has a flange 24;

The protrusion 29 is supported between two fins or wing walls 16 and 17 that are perpendicular to the bottom plate 14 of the molding 1 and fixed in the horizontal direction.

The fin 17 has a vertical flange 28 against which the inner surface of the cover 27 comes into contact, and the bottom plate 14, the fin 17, and the flange 28 form a trough-like passage, and a first side passage 30 It consists of

A further horizontal fin 38 and a perpendicular flange 39 are provided between the channel 30 and the molding wall 3, thus forming a second lateral channel 40 in which the cable 22 is accommodated. are doing.

This cable 22, which is a coaxial cable for television signals, passes through a notch 41 in the cover 27 and is placed under the opening 8 and under the side wall 3.

The terminal end of the cable 22 is connected to a television signal output outlet 42 provided in the platform portion 43 .

The platform part 43 has a fixing hook 44 that hangs on the opening lower part.

The platform 43 has an extension on the lower side so as to form a hood covering the notch 41.

As can be seen from FIG. 2, the platform portion 43 is attached to the end portion 27a of the cover 27.

Although the television signal output outlet is thus fixed to the opening on the power distribution passage, it can be connected to the passage 40 and can cover the outlet of the cable end 22a.

Current electrical regulations require that distribution conductors be placed some distance from points at earth potential.

In the case of baseboard-like installations, it is therefore advantageous to accommodate conductors of small potential, for example weak current conductors such as telephones or antennas, in the available lower space.

In the embodiment according to FIG. 1, these latter conductors are returned to the upper passage as described above.

In the case of FIG. 2, a connector is used which has an extension extending downwardly across passageways 30 and 40.
