Abstract

A venetian blind includes a plurality of slats, rotating means for rotating the slats from a first closed setting through a plurality of open settings to a second closed setting, and indicating means for indicating when the rotating means has rotated the slats to one of a plurality of predetermined desired settings, including at least one open setting. In preferred embodiments of the invention, the means for indicating includes a cam that rotates as the tilt rod is rotated. The cam has a substantially annular perimeter with a number of detents at predetermined locations corresponding to the predetermined desired settings of the slats. A spring clip is biased toward the perimeter of the cam such that a portion of the spring clip travels along the perimeter of the cam when the cam is rotated and engages a detent when it becomes aligned with the detent. The engagement of the spring clip with the detent will provide a visual indication to a user that a predetermined desired setting of the slats has been achieved since the slats will jump to the desired setting as the user rotates the slats to a position that is close to the desired setting. When a desired setting has been achieved further rotation of the slats will be impeded to provide a tactile indication to the user that the desired setting has been achieved.
