  • Upright construction section
    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.
