Abstract

The invention relates to an assembly system (100; 100') for securing an attachment part (8) to a C-rail (1), which has two laterally arranged limbs (2, 3) and two surrounding strips (4, 5) which face the attachment part (8) and are arranged at a distance from each other, said attachment part (8) being pressable against the outer surfaces (28) of the two surrounding strips (4, 5) of the C-rail (1) by means of a screw connection (7; 7'). In order to prevent the C-rail (1) from bending under high loads, the invention proposes a bracket-shaped securing element (17) which is arranged between the attachment part (8) and the surrounding strips (4, 5) when the assembly system (100; 100') is used as intended such that the two limbs (18, 19) of the bracket-shaped securing element (17) at least partly surround the outside of the two laterally arranged limbs (2, 3) of the C-rail (1).

Description

DESCRIPTION
Securing element and assembly system for securing an attachment part to a C-rail The invention relates to a securing element for a C-rail and to an assembly system for fastening an attachment part to the C-rail.
C-rails, in which two laterally arranged limbs are arranged on a base plate and two holding strips which are spaced apart from one another are arranged on said limbs, are usually used for exchangeably fastening attachment or installation parts, for example, to a vehicle. Here, the respective attachment part is pressed onto the C-rail which is arranged fixedly (screwed or welded) on the vehicle, against the outer faces of the two holding strips of the C-rail, by means of an assembly system which comprises a bolt connection.
As a rule, a headed bolt and a slide nut which is arranged in the interior space of the C-rail are used as bolt connection. In the case of the use as intended of the assembly system, the bolt head then bears against the attachment part on the outer side directly or via a washer, and the bolt shank extends through the attachment part and is screwed into the slide nut which is supported on the inner faces of the holding strips of the C-rail.
As an alternative, a T-head bolt and a nut can also be used as bolt connection. Here, in the case of the use as intended of the assembly system, the bolt head of the T-head bolt is supported on the inner faces of the holding strips of the C-rail, whereas the bolt shank is screwed into the nut which is supported directly or via a washer on the outer side of the attachment part.
- 2 -It has proven disadvantageous in assembly systems which are known in this way that the commercially available C-rails can be bent open relatively easily under load, in particular high loads, and the attachment parts can then be ripped out of the C-rail together with the bolt connection.
In order to make it more difficult for the C-rails to be bent open in this way under load, C-rails have been disclosed, in which the holding strips in each case have an oblique profile which is directed toward the interior space of the C-rail. The assembly systems which are used in this case comprise an intermediate part (counterpiece) which is arranged between the slide nut or the head of the T-head bolt and the attachment part, the slide nut or the bolt head of the T-head bolt and the intermediate part having a contour which is adapted to the holding strips on their sides which face the holding strips. During the connection of the attachment part to the C-rail, the holding strips are then also at the same time clamped in between the slide nut or the head of the T-head bolt and the counterpiece.
It has also been shown in practice in the case of said assembly systems that the C-rail can be bent open under high loads which are possibly also associated with a rapid direction change.
The invention is based on the object of specifying an assembly system, by way of which attachment parts can be fastened to a C-rail, bending open of the C-rail under high load being avoided or being made substantially more difficult in comparison with known assembly systems.
- 3 -According to the invention, this object is achieved by way of the features of claim 1. The subciaims disclose further, particularly advantageous refinements of the invention.
;
The invention is based substantially on the concept of using a bracket-shaped securing element which, in the case of the use as intended of the assembly system, is arranged between the attachment part and the holding strips in such a way that the two limbs of the bracket-shaped securing element at least partially engage around the outer side of the two laterally arranged limbs of the C-rail and, as a result, prevent bending open of the C-rail under load or at least make it substantially more difficult. The additionally . incorporated "hasp" preferably locally clasps the C-rail and supports the lateral limbs of the C-rail. A
plurality of hasps or securing elements can also be attached in a manner which is distributed over the length of the C-rail, even at locations where no attachment part is provided. This measure can increase the stability of the C-rail over its length.
Here, the securing element has to consist of a material of corresponding strength (for example, steel) and has to have a wall thickness which ensures sufficient flexural stiffness.
It is not absolutely necessary that the limbs of the securing element and the limbs of the C-rail are in contact with one another, but rather it can certainly be advantageous for the assembly if there is a slight play between said parts and the securing element exerts its effect only when the limbs of the C-rail have bent open slightly.

* WO
- 4 -Once again, for example, a headed bolt with a slide nut or a T-head bolt with a simple nut can be used as bolt connections.
The assembly system according to the invention can also be used in the case of C-rails having holding strips which in each case have an oblique course which is directed toward the interior space of the C-rail, and in the case of which the holding strips are also at the same time clamped in between the slide nut or the head of the T-head bolt and the counterpiece during the connection of the attachment part to the C-rail.
Further details and advantages of the invention result from the following exemplary embodiments which are explained using figures, in which:
fig. 1 shows the cross section through a C-rail, to which an attachment part is fastened by means of a first exemplary embodiment of an assembly system according to the invention, and fig. 2 shows a view which corresponds to fig. 1, with a second exemplary embodiment of an assembly system according to the invention.
In fig. 1, 1 denotes a C-rail which, for example, is welded, screwed, etc. to a vehicle (vehicle housing/vehicle hull 50). The C-rail 1 has two laterally arranged limbs 2, 3 and two holding strips 4,
5 which are spaced apart from one another and are arranged on the limbs 2, 3. Here, the holding strips 4, 5 in each case have an oblique course which is directed toward the interior space 6 of the C-rail 1.
6 An attachment part 8 is fastened to the C-rail 1 with the aid of an assembly system 100 which comprises a bolt connection 7. Here, the bolt connection 7 consists substantially of a headed bolt 9 and a slide nut 10 and an intermediate part 11. The slide nut 10 and the intermediate part 11 in each case have an obliquely running contour 12, 13 which is adapted to the holding strips 4, 5 on their sides which face the holding strips 4, S.
The bolt head 14 bears on the outer side of the attachment part 8, whereas the bolt shank 15 of the headed bolt 9 is guided through the attachment part 8 and the intermediate part 11 and is screwed into the slide nut 10 which is supported on the inner faces 16 of the holding strips 4, 5 of the C-rail 1.
It is then provided according to the invention that the assembly system 100 comprises, in addition to the bolt connection 7, a bracket-shaped securing element 17 which is fixed by way of the bolt connection 7 between the attachment part 8 and the intermediate part 11.
Here, the two limbs 18, 19 of the bracket-shaped securing element 17 engage around outer sides of upper part regions 20, 21 of the two laterally arranged limbs 2, 3 of the C-rail 1 and therefore prevent the lateral limbs 2, 3 of the C-rail 1 from bending open under load. The limb 8 and the securing element 17 can be in one piece or can be connected fixedly to one another.
This assembly simplification can also be extended to the intermediate part 11, with the result that the intermediate part 11 and the securing element 17 are in one piece, or are at least connected fixedly to one another, in the preferred embodiment of the limbs 8.
Fig. 2 shows an exemplary embodiment which corresponds to fig. 1 and in which the assembly system 100' WO *2015/036306 comprises a bolt connection 7' which consists of a T-head bolt 22 and a nut 23. The bolt head 24 of the T-head bolt 22 is supported on the inner faces 16 of the holding strips 4, 5 of the C-rail 1, and the bolt shank 25 is guided through the gap 26 which is situated between the two holding strips 4, 5, the intermediate part 11, the securing element 17 and the attachment part 8 and is screwed into the nut 23 which is supported on the outer side of the attachment part (limb) 8 via a washer 27.
It goes without saying that the invention is not restricted to the above-described exemplary embodiments. For instance, the securing element 17 can also be used in assembly systems, in which the holding strips of the C-rail are arranged horizontally and an intermediate part is dispensed with. In this case, the securing element 17 is supported directly between the attachment part and the outer faces 28 of the holding strips 4, 5 of the C-rail 1.
It goes without saying that relatively small modifications are possible within the context of the invention. For instance, the assembly system 100, 100' can also serve without an attachment part 2 as a securing means for the C-rail per se. Here, the securing element 17 serves for a C-rail 1. By way of the two limbs 18, 19, the bracket-shaped securing element 17 at least partially encloses the outer side of the two laterally arranged limbs 2, 3 and the two holding strips 4, 5 of the C-rail 1 which are spaced apart from one another. The securing element 17 can be connected, that is to say fastened, to the C-rail 1 via the bolt connection 7, 7' as described in the assembly system 100, 100'. Here too, the bolt connection 7, 7' can comprise a headed bolt 9 and a slide nut 10 or a T-head bolt 22 and a nut 23. In the case of a C-rail 1 WO'2015/036306
- 7 -having holding strips 4, 5 which in each case have an oblique course which is directed toward the interior space 6 of the C-rail 1, an intermediate part 11 is arranded between the slide nut 10 or the bolt head 24 of the T-head bolt 22 and the securind element 17, as is also the case in the assembly system 100, 100' (no separate illustration, since it can be gathered from the figure).
