ABSTRACT:
A flange connector for joining forced air duct sections together, consisting of angle bar members attached to the end edges of the duct sections, the cross-section of the angle bars feature parallel and perpendicular flanges that run parallel and perpendicular to the respective enclosing wall of the duct. The angle bar members are connected with corner fittings which feature two pin-like lugs situated perpendicular to each other. In order to maximize the bending strength of the flange connector as a whole, and of the bar members in particular, under conditions of least material usage and at the same time be able to use the flange connection for the joining of firm as well as of flexible duct sections and also maintaining an at least comparable sealing effect compared to existing standards, the cross-sections of the bar members are designed in such a way that the longitudinal outer edges of the flanges have recessed inwardly curled seams facing each other, and a groove at their common bending edge facing from the outer towards the inner section of the angle.
