Profile element and method for manufacturing a profile element

A section element having an elongated section body (2) in which a plurality of openings (5) are formed,

• wherein the section body (2) includes at least two separately formed longitudinal portions (10, 11);
• with each longitudinal portion (10, 11) including a meandering longitudinal edge (12, 13);
• and
• with the longitudinal portions (10, 11) having mutually overlapping regions (28, 29) which are regionally bounded by the meandering longitudinal edges (12, 13);
• wherein connection means (16, 17;
• 30, 31;
• 37, 40) are formed in the overlapping regions (28, 29) via which the longitudinal portions (10, 11) are plugged together in a direction transverse to their longitudinal extent;
• wherein the openings (5) are formed between portions (24, 25) of the meandering longitudinal edges (12, 13) of the two longitudinal portions (10, 11),
• wherein slits (16, 17) extend, starting in each case from the meandering longitudinal edge (12, 13), into the overlapping regions (28, 29) of the longitudinal portions (10, 11) and extend transverse to the longitudinal extent of the respective longitudinal portion (10, 11);
• and wherein the longitudinal portions (10, 11) are plugged together by means of the slits (16, 17).

• wherein locking tabs (30, 37) are formed in the overlapping regions (28, 29) of one or both longitudinal portions (10, 11) and project into locking openings (31, 40) formed in the overlapping regions (28, 29) of the respective other longitudinal portion (10, 11).

A method for manufacturing a section element having an elongated section body (2) in which a plurality of openings (5) are formed, comprising the steps of:

• providing two separate longitudinal portions (10, 11) each having a meandering longitudinal edge (12, 13) to produce the section body (2), with the longitudinal portions (10, 11) having regions (28, 29) which are regionally bounded by the meandering longitudinal edges (12, 13);
• forming connection means (16, 17;
• 30, 31, 37, 40) in the regions (28, 29) for the plugging together of the longitudinal portions (10, 11);
• moving apart of the longitudinal portions (10, 11) transverse to their longitudinal extent such that the regions of the two longitudinal portions (10, 11) overlap, the longitudinal portions (10, 11) being plugged together via the connection means (16, 17;
• 30, 31, 37, 40);
• and the openings (5) being formed between portions (24, 25) of the meandering longitudinal edges (12, 13) of the two longitudinal portions (10, 11), and
• forming slits (16, 17) for the production of the connection means which respectively extend from the meandering longitudinal edge (12, 13) into the regions (28, 29) of the longitudinal portions (10, 11) and extend transverse to the longitudinal extent of the respective longitudinal portion (10, 11).

• and
• engaging the locking tabs (30, 37) into the locking openings (31, 40) on the moving apart of the longitudinal sections (10, 11).
