DESCRIPTION

Mounting element and centering unit for a mounting element TECHNICAL AREA

The present invention relates to a mounting element, in particular mounting bracket, with at least one joining surface, which has at least one centering unit with a projection protruding from the joining surface, wherein the centering unit is detachably insertable on the mounting element.

The invention further relates to a centering unit for profile elements connecting mounting elements with grooves, wherein the centering unit has a body region with a projection, which can be detachably arranged in a recess of the mounting element.

Aluminium profiles with external grooves are often assembled in the industrial sector to form supporting structures for devices.

STATE OF THE ART

When assembling aluminum profiles, mounting brackets without centering are known.

The closest prior art is described in &Xgr;&Rgr;-&Agr;-0183395, an assembly element which has a centering means for centering on a joining surface, which is designed as a projection protruding from the joining surface. However, it happens that assembly tasks can also be solved without centering, so that in this case the projection has a disruptive effect.

EP 0469284 discloses a mounting bracket with cast-on centerings, in which the centerings have a predetermined breaking point for removing them. However, the user of such elements is restricted to a specific profile groove which corresponds to the dimensions of the centering. When using the brackets for cases in which the centerings are not required, the effort required to break off the cast-on centering lugs is considerable.

DESCRIPTION OF THE INVENTION

Based on the above-mentioned prior art, the present invention is based on the technical problem or task of specifying a mounting element that can be designed without great effort as both a centerable and non-centerable mounting element that ensures secure locking of the components or profiles to be connected, whereby the connection of profiles with different profile groove dimensions should also be made possible. The invention is also based on the task or technical problem of specifying a centering unit that can be used variably with mounting elements, ensuring secure centering even when components with different profile groove dimensions are connected.

The mounting element according to the invention of the type mentioned at the outset is given by the features of claim 1. Advantageous embodiments and further developments are the subject of the dependent claims 2 to 8.

The mounting element according to the invention is therefore characterized in that the centering unit has at least two arranged 35

has projections with different cross-sections or different centering widths (A, B) and/or the centering unit has elements molded on at a predeterminable angle, in particular 90 degrees, which have a projection, so that a substantially L-shaped unit is formed, wherein according to a particularly preferred configuration the centering unit is designed to clamp in a recess, in particular a groove, of the mounting element on the joining surface side.

By creating a plug-on centering unit, the respective unit can be easily adapted to the existing construction. Different designs of the projections with regard to the centering width enable the use of the mounting elements with different profiles and dimensions. In particular with mounting brackets, it is easy to connect two profile bar elements in a centering manner that have different profile groove dimensions.

In applications where centering is not desired, the centering unit is not used, so that in such tasks the disruptive influence in the known embodiments does not occur at all.

A particularly preferred embodiment of the mounting element according to the invention is characterized in that the centering unit has two projections arranged opposite one another on the outside with different cross sections or different centering widths. As a result, one and the same centering unit can be used for centering on profile bar elements with different profile groove dimensions by simply turning it.

The L-shaped centering element is used for mounting brackets, where it is attached to the 90-degree corner of the bracket

This means that by using only one centering unit, a good overall centering of two profiles can be achieved.

According to a preferred embodiment, the centering width of the projections of the elements is different, so that profiles with different profile groove dimensions can also be connected to this one L-shaped centering element.

Particularly good handling can be achieved by having the assembly element with a centering pin, on which the centering unit can be plugged and which is located below or in the joining plane. When the assembly element is designed as an assembly angle, the centering pin is preferably arranged in the direction of the division of the injection mold, i.e. it is located, for example, in the corner point of the 90-degree corner of the angle and forms an angle of 135 degrees with the adjoining legs. This means that the use of an expensive tool slider during the manufacturing process can be omitted.

A good centering effect can be achieved by making the projection shape square or rectangular when viewed from above with a centering width corresponding to the profile groove width. Such a centering element is preferably arranged in the area of the ends of the legs of the mounting bracket for centering purposes.

The centering unit according to the invention is given by the features of the independent claim 9. Advantageous embodiments and further developments are the subject of the dependent claims 10 to 13.

WAYS TO CARRY OUT THE INVENTION

Fig. 1 shows schematically the right-angled connection of a profile 30 to a continuous profile 32 by means of a mounting element 10, which is designed as a mounting bracket. Both profiles 30, 32 have a continuous groove 34, 36 on the four outer sides, which groove is not shown on all four sides of the profiles 30, 32 in Fig. 1. The mounting bracket 10 has two legs 11 that are at right angles to one another and are stiffened by a triangular reinforcing rib 13 arranged on the side. In the area of the center line of each leg _g_

11 has two elongated holes 15 through which a hammer head screw 22 anchored in the groove 34 or 36 can be passed and through which a clamping nut 24 with washer 26 can be used to create a clamping with the profiles 30 or 32.

For centering purposes, a centering unit 14.1 is arranged between the profiles 30, 32 and the mounting bracket 10 for each leg 11.

The centering unit 14.1 is shown in more detail in Fig. 2 a) and 2 b). The mounting element 10 has a groove recess 18 on the outer sides of the legs 11 facing the profiles 30, 32, into which the centering unit 14.1 can be inserted (Fig. 2b)).

The centering unit 14.1 has a cuboid-shaped body area 17, the width of which essentially corresponds to the width of the recess groove 18, and the centering unit 14.1 can thus be arranged in a releasably clamped manner in the recess 18. A cuboid-shaped projection 16.1 with a width A is formed on the upper side of the body area 17. Opposite, on the lower side, a cuboid-shaped projection 16.2 with a width B is formed on the body area 17. The widths A and B correspond to the widths of the grooves 34 and 36 of the profiles 30 and 32. Profiles with a profile groove width A or a profile groove width B can thus be centered with the centering unit 14.1. For this purpose, the centering unit

14.1 into the recess groove 18 of the mounting bracket 10 in such a way that the corresponding projection 16.1 or

16.2 protrudes upwards, which is possible by simply turning the centering unit 14.1.

In Fig. 3,4 a) and 4 b) the same mounting situation is shown concerning the right-angled connection of the profile 30 to the

Profile 32 is shown. Identical components have the same reference number and are not explained again. The difference from the embodiment described above is that a centering unit 14.2 is used for centering purposes, which has two body areas 19 formed at right angles to one another, the width of which essentially corresponds to the width of the recess 18 of the legs 11 of the mounting bracket 10. A projection unit 16.1 is formed on the outside of this body area 19, the width of which corresponds to the respective groove width of the profile to be connected. In this embodiment, it is therefore possible to center both profiles 30 and 32 to be connected using a single centering unit 14.2.

Fig. 5 shows a further variant of the mounting bracket 10 and the L-shaped centering unit 14.2. In the corner area of the mounting bracket 10, a centering pin is formed onto which the centering unit 14.2 can be plugged due to a corresponding recess, with the body area 19 still being arranged within the recess groove 18.

Fig. 9 shows schematically the usability of an L-shaped centering unit 14.2 in the corner area and the other possibility of centering by inserting two centering units 14.1 in the end area of the legs 11 of the mounting bracket 10.

Fig. 7 shows a schematic cross-section of a centering unit 14.3, in which the projection unit 16.1 and 16.2 are formed in a step-like manner on the upper side of the body region 17.

Fig. 8 shows a schematic cross-section of a centering unit 14.4, in which a pre-35

jump unit 16.1 and a projection unit 16.2 is formed on the upper side in a stepped manner.

With the centering element according to the invention, simple and safe centering can be achieved. Profiles with different profile groove widths can be centered without any problem. Thanks to the detachable connection with the mounting bracket, no problems arise even if centering is not desired, since there are no "disturbing" pre-10 jump units.
