Abstract

Ein Schneckenantrieb zur Winkelpositionseinstellung von Vertikallamellenjalousien mit einer innerhalb eines Lamellenträgergehäuses (10) angeordneten Vertikalachse (15), die ein hiermit drehfest verbundenes Ritzel (19) trägt und endseitig mit einer Lamelle (17) in Verbindung steht, wobei mit dem Ritzel (19) eine über eine Innenprofilierung durch eine Antriebswelle drehbare Schnecke (23) in Antriebseingriff steht, zeichnet sich durch eine Schnecke (23) mit einer axialen Mittelöffnung aus, die mittels einer Schnapphülse (25) unter wesentlich vereinfachter Montage und verringerter Bautiefe des Lamellenträgergehäuses (10) auf einem rohrstutzenförmigen Vorsprung (22) des Lamellenträgergehäuses (10) gehalten ist. Die Schnecke (23) ist mit einer Innenzahnung (31) versehen, die mit am Außenumfang der Schnapphülse (25) angeordneten Nocken (30) in Eingriff steht und damit eine Rutschkupplung bildet, die ein schadloses Überdrehen der Schnecke (23) gestattet infolge der begrenzten Drehmomentübertragung. A worm drive for angular position adjustment from Vertical slatted blinds with one inside a slat carrier housing (10) arranged vertical axis (15), which hereby rotatably connected pinion (19) carries and at the end with a lamella (17) is connected, one with a pinion (19) Internal profiling by a worm gear (23) rotatable in Drive engagement is characterized by a worm (23) with an axial central opening made by means of a snap sleeve (25) with significantly simplified assembly and reduced Construction depth of the disk carrier housing (10) on a Pipe socket-shaped projection (22) of the plate carrier housing (10) is held. The worm (23) has an internal toothing (31) provided with the outer circumference of the snap sleeve (25) arranged cam (30) is engaged and thus a slip clutch forms, which is a harmless overtightening the worm (23) allows due to the limited torque transmission.
