Fastening device on a support frame for electrical devices

The innovation relates to a fastening device on a supporting frame for electrical devices for detachable Enhancement in a control cabinet, with the supporting structure • including two parallel, lined up LBngaatllben, There are special channel-shaped profiles which are connected to one another by means of cross struts, and wherein at least one cover hood detachably connected to the framework is provided.

So far, such support devices have been used in switchgear bars by means of several, the LöngsBtBbe more radical Screws fastened.

That type of attachment is relatively cumbersome and time-consuming, especially if, after assembly, the scaffolding is used for maintenance, troubleshooting and / or supplementation the system must be loosened and reattached.

The object of the invention is now, with simple means, ways to accelerate the assembly or « to create dismantling of the scaffolding.

This task is solved by the following features: Kattuiinkel 7603 / ΒΊ "

I) every LJngaetab is a stationary bracket to be held assigned, which opens up an inlet opening that opens out at the top and interacts with the lower longitudinal rod end part,

i) with Abatand above the console iat in each LMngsstab at least one length of its calibrated keyhole arranged, of the head bolt, which is to be held in a fixed position and which is directed transversely to the longitudinal extension of the longitudinal rod corresponds, including the bolt head push-through opening The keyhole is arranged on the laugh end part facing the console, and

C) the cover attached to the scaffolding is attached to the consoles

al supporting, relative displacements to that Scaffolding and bland plate locking the consoles.

As a result of these measures, the scaffolding is now held in a fixed position only in a detachable manner by means of plug-in connections, the protective cap has been used to secure it, resulting in the desired simplification of assembly.

A preferred, technically inexpensive to manufacture and a High positional security of the scaffolding guarantees the use of the consoles, the consoles Jeuieile the Have the shape of a Hakena with a hooked maui open at the top, into which the facing guest evening part from above is inserted and that the free hook end part is inserted into the channel of the gutter-shaped profiled Lingbar end partB formachüeBend engaging rib is arranged.

It is advantageous if the Makenffiaul upwards is formed widening wedge-ready.

This results in a further simplification of assembly in such a way that the scaffolding with the upper end part to the front can be inserted inclined into the consoles.

In addition, to simplify assembly, it has proven to be advantageous if the head bolts are each from one Abatreben base, the thickness of which is the thickness of the hook part a which supports the Lgngsstabendteil on the back.

This inevitably results in a constant idandab band of the scaffolding achieved.

Kattuinkel 76Q3 / B1

A dieitere9 feature that increases electrical safety of the above-described subject is that the Honsolen and the headed stud socket are made of insulating material.

For the space-saving arrangement of the scaffolding in a control cabinet or a preferably lockable one at the front In a niche, it is also advantageous if the brackets and the cap bolt base are arranged in this way to the length of the scaffolding are that their outsides are flush with the outsides of the consoles and the headed bolt base.

An exemplary embodiment of the invention is shown in the drawing and is described in more detail below.

Show it:

Fig. 1 shows part of a supporting frame for electrical devices in longitudinal section,

Fig. 2 also seen along the line H-II of Fig. 1,

FIG. 3 likewise in section HI-III of FIG. 1.

This shoring consists of vertically arranged, Length blocks 1 held parallel to each other C-shaped profile, from the front of each at least a bracket 2 strives.

Kattuinkel 76D3 / B1 The latter bind bridged by means of a cross strut 3.

Furthermore, a cover k releasably attached to the consoles 2 is provided.

For the detachable mounting theeaee constituting an assembly unit Support frame on the rear wall 5 of a switch cabinet is each longitudinal rod 1 on the front associated with the rear wall 5 supported bracket 6.

The latter has the shape of a hook with a hook mouth that is open at the top, into which the lower part of the evening meal is inserted from above plugged in.

The width of each bracket 6 is equal to the profile width of a longitudinal bar 1 and the latter are like the brackets 6 arranged that their sides with the long sides of the Finish LBngsBtäbä 1 flush.

From the inside of the free hook end part 7 a strives Into the gutter of each LSngsstabes 1 form-locking & ad engaging Rib θ. The one that supports the LMngsstab 1 on the back Hook part 9 is glued to the front of the cabinet back and 5, for example.

The width of the mouth at the base of the hook mouth corresponds to that Profile height of a Lgngastabee 1.

Furthermore, the hook mouth extends upwards in a new way educated.

Above the consoles 6 and at a distance from them in each LSngsstab 1 with a fixedly held one Head bolt 10 cooperating keyhole 11 is provided, uiobbe the bolt head through-hole 12 on the the end part of the keyhole 11 facing the cone 6 is arranged. The distance of the keyhole 11 from the lower end of the longitudinal rod is chosen so that the head bolt Holds the IMing rod in place when the lower end of the longitudinal rod eich is supported at the bottom of the console hook mouth a. The head bolt 10 strives from the front side of a base 13 fastened to the cabinet back 5.

The thickness of the base 13 corresponds to the thickness dbB of the hook part 9.
The base 13 and the consoles G are made of insulating material.

To secure this detachable plug connection, the cover U, which is releasably attached to the consoles 2, is designed and arranged in such a way that the lower side wall of the cover k is supported on the undersides of the consoles 6,

Kattiiiinkel 76G3 / B1

This can be seen from FIG. 1.

For the releasable connection of the cover k to the consoles 2, screws can be provided. Preferably, however, connection means H 'which are effective in the manner of a bayonet lock and are known per se are provided.

The longitudinal sides of the base 13 are arranged flush with the longitudinal sides of the longitudinal rods.

All new individual and combination features disclosed in the description and / or drawing are used regarded as essential to the invention.
