| 摘要 |
The invention relates to a profile bar (2), in particular an extruded profile made of a lightweight metal alloy, preferably an aluminum alloy, with at least one undercut longitudinal slot (6) which has a slot bottom (8) and extends in the direction of the longitudinal extent (L) of the profile bar (2), and of which the longitudinal slot opening (13) opposite the slot bottom (8) in the direction of a longitudinal slot height (H), perpendicular to the longitudinal extent (L) of the longitudinal slot (6), is bounded by two undercut sections (14, 15) separated by the longitudinal slot opening (13), wherein a longitudinal slot opening width (b), measured perpendicular to the longitudinal extent (L) of the longitudinal slot (6), is less than a maximum longitudinal slot width (bn) in a longitudinal slot region located below the undercut sections (14, 15) as seen along the longitudinal slot height (H). According to the invention, it is provided that, below the slot bottom (8), there is provided a longitudinal duct (9) which extends parallel to the longitudinal slot (6) and which is separated from the longitudinal slot (6) by a section (7) of profile bar material that forms the slot bottom (8) and is formed as a penetration section and/or a molded section. |
