ABSTRACT:
A miniblind comprises a head rail, a tilt rod disposed within the head rail, a tilt actuator operatively connected to the tilt rod and operable to rotate the tilt rod, and a cam housing disposed in the head rail. The cam housing includes a cam non-rotatably connected to the tilt rod and rotating therewith, the cam having a protrusion, and at least one adjustable rotation restrictor extending within the housing, wherein rotation of the tilt rod is restricted by abutment of the cam protrusion against the at least one adjustable rotation restrictor. The cam housing includes at least one threaded bore extending therein from a side thereof to a position adjacent the cam, and at least one threaded member which can be adjusted to move along a length of the threaded bore. The bore is aligned with the at least one head rail aperture. The miniblind is adjusted by inserting a tool through the at least one head rail aperture and the at least one bore to engage the at least one threaded member to move the threaded member along the length of the threaded bore, thereby adjustably restricting rotation of the tilt rod by abutment of the cam protrusion against the at least one adjustable rotation restrictor.
