Description

The invention relates to an angle profile-shaped tab according to the preamble of claim 1.

Such butt joints of perforated profiles are in general using tabs or flat or angularly shaped plates made on the perforated profiles to be connected by screwing with nuts / screws or by folding down from before projections inserted into the holes of the perforated profiles be attached.  

EP 0 83 809 A1 describes one known angle-shaped tab, whose first leg is designed so that it to a side leg of each of the two connecting perforated profiles over the full height of this since Lichen leg rests and pivoted on this is attached by overlapping the free edges. The second leg of the tab is with a row of protruding sections provided are designed to match those in the floors of the perforated edges to be connected come to the intervention.

These tabs have the advantage that they are very easy to attach to the perforated profiles to be connected are, but they have the disadvantage that they themselves within the profiles to which they are attached an obstacle to what when laying cables mean a great disability in these profiles can, because this relocation usually happens by pulling the cables that are then in the Slide profiles.

It is therefore an object of the invention to provide an angle profile-shaped tab of the kind in question to create a simple connection of two a perforated profiles forming a cable channel and the laying of cables facilitated.

This task is performed in a generic tab by the characterizing part of claim 1 specified features.  

In a further embodiment of the invention protruding sections of the tab an asymmetrical cross profile such that it is on the side of the second leg that comes into engagement with the perforated profile are delimited by two inclined planes, one of which the one oblique facing the first leg Level is strongly inclined, while the other is inclined Plane is only slightly inclined.

In a further embodiment the projecting sections from to Inside the tab half pushed out and towards the Winkelbe surrounding this tab half-open projections.

Preferred embodiments of the Invention described with reference to the drawing. Here demonstrate:

Figure 1 is a perspective view of one end of a perforated channel provided with a connecting tab according to the invention.

Fig. 2 u. 3 in cross section and on an enlarged scale a detail of this arrangement in two embodiments;

Fig. 4 schematically shows the attachment of the tab according to the invention on a channel.

The illustrated perforated profiles 1 to be connected are U-shaped cable ducts in which not only the bottom 2 but also the legs 3 are provided with longitudinal rows of elongated holes 4 .

In order to connect these channels abutting, two identical tabs 5 - one for each side - are used.

Each tab 5 is L-shaped with a vertical leg 6 and a horizontal leg 7 .

The vertical leg 6 is dimensioned such that it bears over the full height of the outside of each leg 3 of the channel, but not beyond this height, and that it is pivotably suspended at the edge 8 of this leg 6 .

For this purpose, the upper edge 8 of the leg 6 is bent inwards with a curvature of 180 ° or more, the folded edge 8 thus obtained being large enough to cover the upper edges 9 of the leg 3 of the channel.

These upper edges 9 are stiffened in a manner known per se.

The horizontal leg 7 of each tab is equipped with longitudinally aligned expressions 12 which project slightly upwards from this leg 7 .

These expressions 12 are dimensioned and arranged so that they snap into the holes 4 of the channels when the tabs 5 are attached to the channels.

The expressions 12 are thus arranged in a division corresponding to the division of the holes or in a division forming a multiple thereof.

They are formed by local deformation of the leg 7 in question.

It is e.g. B. by half pushed out projections, as shown in FIGS. 1, 2 and 4, or from bulges as in Fig. 3rd

These expressions 12 have a maximum height accordingly the thickness of the bottoms 2 , so that they do not protrude inside the perforated profiles 1 .

In the event that tabs 5 and perforated profiles consist of rolled sheet of the same thickness, this height is practically equal to this thickness: in other words, when the projections are half pushed out, the cut surface of each projection lies directly on the surrounding sections of the sheet, with at most one forms an almost invisible gap between the two, on the side of the projection facing the vertical leg 6 .

The expressions 12 preferably have an asymmetrical cal profile such that they are limited on the side coming into engagement with the perforated profile 1 by two inclinations on both sides of the central plane of the leg 7 , one of which is very strongly inclined and the other of which is only slightly inclined, the vertical leg 6 of the tab 5 facing inclination is more pronounced.

This asymmetrical arrangement of the expressions 12 facilitates assembly and makes them irreversible when they snap into place.

This assembly is done in the following way.

First you arrange the two channels to be connected butting one behind the other.

Then one folds over the two opposite sections of the two edges 9, the edge 8 of a flap 5 tilted on the horizontal, as shown in FIG. 4.

Then one introduces this tab 5 , by pivoting it in the direction of arrow F around the horizontal line of contact between the edge 9 and the folded edge 8 , whereby the horizontal leg 7 approaches the floor 2 and slides under it, then the Tips of the expressions 12 of the legs 7 slide along the bottom 2 until the expressions 12 snap into the holes 4 by resilient expansion.

This completes the assembly.  

The connection obtained in this way is very solid, because the disengagement of the expressions 12 from the holes 4 would require special printing tools.

In addition, the assembly in question is very simple and fast and happens without help a tool or other additive, what a represents valuable advantage of the invention.

Furthermore, it should be noted that no expression 12 protrudes inside the perforated profiles 1 which are joined together, so that cables can slide in these perforated profiles 1 without any obstruction.

Finally, it remains to be noted that the holes 4 used for snapping are adjacent to the base line of the leg 3 of the profile in question, and that the pressure of the snapping is due to the fact that the practically identical heights of the two pivotably arranged legs of the channel 3 and the Tab 6 remain completely constant during and after assembly, the two legs 3 and 6 being supported on one another and being deformed neither by train nor by pressure.

In order to ensure a very close contact of the tabs 5 with the surfaces in question of the perforated profiles to be connected, the angle formed by the two legs 6, 7 of each tab 5 is formed somewhat below 90 °. The connection is then created by a slight elastic opening of the tabs 5 .

In order to be able to correct the longitudinal position of each tab 5 in relation to at least one of the perforated profiles 1 to be connected to a certain extent, the pressures 12 are made shorter in the longitudinal direction than the holes 4 into which they snap. In this way, it is possible to connect dimensional perforations and / or different distances on slid-transmitting slideways and / or between the slideways 5 connected with the aid of the tabs in question either in the longitudinal direction or to leave very little play.

The number of expressions 12 of each tab 5 , which engage in each perforated profile 1 , is preferably at least two.

Of course, in all cases the distance between the expressions 12 and the vertical leg 6 of the corresponding tab 5 is equal to the distance between the holes 4 , in which these expressions 12 are to engage, and the adjacent leg 3 of the correspond to the hole profiles 1 , so that in When the two legs 6 and 3 engage, they snap together.

Accordingly, regardless of the embodiment chosen, a tab 5 is finally obtained for connecting perforated channels, the structure, application and advantages of which emerge from the foregoing.
