  • Publication number: 20120240488
    Abstract: The invention relates to a profiled element, in particular a profiled construction element, for example a profiled dry construction, façade, or plaster element, comprising an in particular metal elongated main body, in which at least one opening is formed. The opening has at least one edge formed transversely to the longitudinal extension of the main body, which edge is formed at least partially by a bent-over section of the main body. The bent-over section, together with an adjacent section of the main body, forms an at least double-layer area of the main body. In order to increase the stiffness of the profiled element transversely to the longitudinal extension thereof, the bent-over section is connected to the adjacent section within the at least double-layer area. The invention further relates to a method for producing such a profiled element.

  • Patent number: 7574838
    Abstract: A profiled rail for supporting plate-shaped elements, particularly for inlay mounting of ceiling plates for louvered ceilings includes a base body, having a T-profile in select areas, a longitudinally extended web and a lower flange. The lower flange runs along a longitudinal edge of the web and comprises two lower flange sections each extending from the web essentially in opposite directions. The lower flange is formed by bending the web. The side of the lower flange, which is oriented away from the web, is provided with a facing board. A multitude of openings are provided in the web, whereby at least one of the lower flange sections is formed by material sections of the web that are folded out from the openings. The web is provided as a single layer essentially over its entire surface. A method for producing a profiled rail of this type is also provided.

  • Patent number: 6434903
    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.

  • Patent number: 6381916
    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.
