Abstract:
A coupling member, for the face end coupling of profile bars (1, 2) that are composed of light metal and have undercut longitudinal grooves (3) covered by profile walls (4) except for an opening slit (5), wherein a first profile bar (1) is butt-jointed with one face end to a side wall of a second profile bar (2) and the coupling member (6) is inserted into longitudinal grooves (3) that align in one plane,the coupling member comprising an elongated counter holder (10) that is insertable into the longitudinal groove (3) of the first profile bar (1), and a tension tie (7) incorporating both, a shaped head (8) that is to be inserted into the longitudinal groove (3) of the second profile bar (2) and hooks into the profile wall (4) of the longitudinal groove (3) from behind, and a shaft (9) that is connected to the counter holder (10), wherein the counter holder (10) is pivotally connected to the tension tie (7) by means of a pivot (11) that hooks from underneath into the profile walls (4) adjoining the opening slit (5) and is provided on one side with a tooth system (13) that penetrates at least partially into the profile wall (4) in the region of the groove bottom of the longitudinal groove (3) when the coupling member (6) is tightened by pivoting the counter holder (10) from an insertion position, in which the counter holder (10) projects from the longitudinal groove (3), to a tightened position, in which the counter holder (10) is received inside the longitudinal groove (3), so that the counter holder (10) moves away from the second profile bar (2) during tightening while fastening the profile bars (1, 2).
