Abstract: A section fixable in a mounted position to an anchoring base by means of fastening screws has at least one fastening segment extending in the mounted position substantially parallel to the anchoring base. The fastening segment is, for example, a fastening flange, which is provided with at least one screw hole for receiving a fastening screw provided with a slot or cross slot as the surface engaged by a screwdriver. A safety (or securing) tab protrudes from the fastening segment at least within the area of the screw hole. When the section is in its mounted position and after the fastening screw has been driven in, the safety tab can be deformed by bending or folding it into its safety or securing position. In this position, the tab grips over the edge of the screw head of the fastening screw and leaves free the surface engaged by the screwdriver. In an alternative embodiment of the section, a spring-elastic safety arrest is used instead of a bendable safety tab.

Abstract: An upright section having two section legs extending spaced from each other in the longitudinal direction of the section and connected with each other by a section bridge. The section bridge is equipped with at least one elastic segment having low transverse spring temper and extending in the longitudinal direction of the section. The elastic segment is shaped out of the plane put up by the section bridge and connects the section legs with bending elasticity. Since the section bridge is equipped with at least one elastic segment extending lengthwise, the upright section is divided in two section parts that are connected with each other only via the elastic segment arranged between the two parts.

Abstract: In a lightweight longitudinal angled section, particularly a cover-carrying profile, which includes two legs spaced from one another extending along the longitudinal direction, wherein a longitudinal bar connects the legs, and each leg is formed with stiffening devices, which, in turn, include at least one longitudinal impression, each leg has a free longitudinal end facing away from the bar, and wherein the free longitudinal end is formed with a longitudinal flange extending approximately parallel with the bar so as to face inwardly, the improvement includes longitudinal edge portions connecting respective legs to the bar, corrugations which extend transverse to the longitudinal direction along each leg up to the longitudinal impressions, and therebeyond to the longitudinal edge portions, and at least partly over a portion of the width of the bar, and wherein the corrugations are spaced from one another at substantially identical distances.
