ABSTRACT:
A tilter mechanism for the slats of a venetian blind in which a worm and wormwheel are mounted in a housing connected to a bracket, the wormwheel has an axial extension on each axial end provided with a recess which can receive selectively the end of a tilt rod, whereby the tilt rod can extend either to the left or to the right of the wormwheel. A spring clip holds the tilt rod in engagement with the recess in one of the extensions. A rotational control disc may also be provided which has two external abutments.
This disc can be mounted on the other of the extensions, the abutments being engageable with stops on the bracket to restrict rotation of the control member and thus of the wormwheel. Radially outwardly extending keys are provided on each extension, one of these engaging the spring clip to hold the tilt rod in place, and the other engaging a notch in the rotation control disc to prevent the latter rotating relative to the wormwheel.
