Abstract

A hollow profile has at least one internal partition for forming chambers, in which, in order to fix an attached part to the hollow profile, an insert part is arranged in a mounting position within one chamber, and the insert part has a connecting means for producing a connection to the attached part. The insert part is formed as a multi-chamber profile having a profile direction extending perpendicular to the profile direction of the hollow profile and perpendicular to the partition, for an interface of the insert part, resting on an outer boundary wall of the hollow profile, to have a journal-like connecting flange which, in order to fix the insert part in the mounting position, engages with a form fit in a through opening in the boundary wall. The insert part is formed with a length in the profile direction of the insert part so as to enable insertion of the insert part into the chamber of the hollow profile and for positioning the same in the mounting position.

First claim

What is claimed is:

1 - 8 . (canceled)

9 . A hollow profile, comprising:
at least one internal partition wall forming chambers of the hollow profile; and an insert part configured as multi-chamber profile and arranged in a mounting position inside one of the chambers, said insert part having a profile direction which extends perpendicular to a profile direction of the hollow profile and perpendicular to the partition wall, said insert part having a connection means for forming a connection with an attachment part, to thereby fasten the attachment part on the hollow profile, said insert part having an end face which rests against an outer boundary wall of the hollow profile and a connection flange protruding from the end face and fittingly engaging in a through-opening of the boundary wall, thereby fixing the insert part in the mounting position, said insert part having a length in the profile direction of the insert part which enables insertion of the insert part into the chamber of the hollow profile and positioning of the insert part in the mounting position.

10 . The hollow profile of claim 1 , wherein the insert part has contact surfaces, which in the mounting position of the insert part rest substantially flat against sidewalls of the chamber which are situated adjacent the boundary wall.

11 . The hollow profile of claim 10 , wherein the sidewalls have at least one fastening opening provided in a region of the contact surfaces of the insert part for connecting the insert part with the hollow profile.

12 . The hollow profile of claim 10 , wherein the sidewalls of the hollow profile are connected with the contact surfaces of the insert part by way of a frictional connection and/or a material-to-material connection.

13 . The hollow profile of claim 9 , wherein the connection means is configured as a connection bore extending in the profile direction of the insert part and through the connection flange.

14 . The hollow profile of claim 13 , wherein the insert part has a cylindrical profile element, which receives the connection bore, said cylindrical profile element being connected with outer sidewalls of the insert part via web walls so as to form chambers of the insert part.

15 . The hollow profile of claim 14 , wherein the outer sidewalls are provided with the contact surfaces.

16 . The hollow profile of claim 9 , wherein the connection flange has an end face which is aligned with the outer surface of the boundary wall, said hollow profile further comprising an intermediate disc having a bore which is congruent with the connection bore, said intermediate disc resting flat on the end face of the connection flange and on the outer surface of the boundary wall surrounding the connection flange.
