Abstract:
An articulated-arm awning comprising at least two articulated arms (1), each articulated arm (1) incorporating an inner and outer articulated arm section (2, 3) that are connected to one another by means of a joint (4) having a first swiveling axis; the outer articulated arm section (3) of each articulated arm (1) being connected in the region of its outer end to a dropout profile (11) by means of a joint (9) having a second swiveling axis (10); the inner end of each inner articulated arm section (2) being connected to a bearing on the building side by means of a joint (5) having a third swiveling axis (6); a tilting joint (7) that is rotatable around a horizontal swiveling axis being provided on each articulated arm (1); wherein the inner and outer articulated arm sections (2, 3) and joints (5, 9) are dimensioned and positioned such that when the dropout profile (11) is retracted, a lateral force parallel to the dropout profile (11) or building wall is exerted onto a tilting shaft (12) that has a horizontal longitudinal axis that extends along the horizontal swiveling axis and is mounted so that it can slide parallel to the horizontal longitudinal axis (15); wherein the tilting shaft (12) is mounted so that it can slide in the direction of the lateral force against the force of a spring (18); wherein a clutch (10) is provided that can be activated and deactivated in dependence upon this sliding movement of the tilting shaft (12) such that when the dropout profile (11) is retracted and the lateral force correspondingly exceeds that of the spring (18), the clutch (19) is disengaged and permits a swiveling of the tilting shaft (12) around the horizontal longitudinal axis (15), and that when the dropout profile (11) is extended, the clutch (19) is engaged and blocks the swiveling; and wherein the first, second and third swiveling axis are all perpendicular to the horizontal longitudinal axis.
