Frame made of hollow profiles

The profiles intersect at one or more points (3). At the intersection one or more of the profiles (2) has a cut-out in which a further profile (1) is positively held. A foamable compound applied onto the profiles at least within the region of the intersection forms a positive and/or semi-positive connection with the profiles and grip then firmly to create a rigid frame. An Independent claim is made for a process for manufacturing a frame in which: (a) a first hollow profile (2) with a cut-out for a second profile (1) is located in an open die casting mold; (b) a second hollow profile is placed in the mold so that it rests in the cut-out at the intersection with the first profile; (c) the mold is closed to hold both profiles and a compound is then foamed to fix their positions.
