Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
147 words
A venetian blind tilt operating mechanism comprising a head rail, a tilt rod journaled in said head rail and rotatable for tilting slats, operating means for rotating said tilt rod in opposite directions, a mounting member non-rotatably positioned in said head rail adjacent to said tilt rod, said mounting member having a guideway partially surrounding said rod, a radial extension on said rod extending into said guideway and rotatable with said rod for swinging in said guideway, and stop members positioned in said guideway for limiting engagement with said rod extension to limit tilting movement of slats, said mounting means comprising a plate extending conformably across said head and, said radial extension including a hub on one side of said plate, an offset portion extending from said hub through said guideway, and a terminal portion extending from said offset portion on the other side of said plate.
Claim 2
Dependent Claim
