A structural support or connecting member for window frames achieves an improved transmission of forces effective on a window frame, a simplified and less expensive manufacture and installation, an improved reliable sealing against infiltration of water and air, and an improved thermal insulation. In the system a window frame component to be connected to the connecting member has at least one lengthwise extending slot on its side facing support member. The support member or connecting member is assembled of two similar or mirror-symmetrical essentially flat sectional elements (9, 9') attached to each other in a mirror-symmetrical fashion to form two hollow chambers (7a, 8a) which extend in parallel to and at a spacing from each other, and which are open laterally through open lengthwise channels (6, 6'). The bar members (9, 9') of the carrier further include at least one engaging flange (10, 11) which can respectively be inserted into and engage the slot (14, 15) of the window frame component (13) in a force transmitting manner.
A support member for connection to a structural frame component, such as window frame components having at least one lengthwise slot (14, 15) facing said support member (1), comprising two sectional elements (9, 9') each having two pleated sections (7, 8;
A frame system, comprising at least one structural frame component having at least one lengthwise slot facing a neighboring structural component, a connecting member connected to said at least one structural frame component, said connecting member comprising two sectional elements (9, 9') each having two pleated end sections and a flat intermediate section between said pleated end sections, means interconnecting said two sectional elements along said flat intermediate section lengthwise in a mirror image arrangement, said pleated end sections forming two lengthwise extending hollow chambers (7a, 8a), and two lengthwise extending channels (6, 6') each opening laterally from the outside into a respective hollow chamber (7a, 8a), said sectional elements (9, 9') further comprising at least one engaging flange (10, 11) insertable into said lengthwise slot (14, 15) of said frame component (13) for engaging said slot (14, 15) in a force transmitting manner.
