Pitch adjustment divider for venetian blinds

A pitch adjustment apparatus for selective attachment to at least three existing chord assemblies of an existing venetian blind assembly, to selectively adjust the pitch of a plurality of slats located below the pitch adjustment apparatus, which comprises:

• a) at least three pitch adjustment housings, each with a first aperture and a second aperture positioned below the first aperture, the second aperture perpendicularly aligned in relation to the first aperture;
• b) a slotted pitch adjuster positioned within the first aperture of each of the pitch adjustment housings, each slotted pitch adjuster with a slot extending past a first end, the slot aligned with a neck portion extending about the outer periphery of the pitch adjuster near the first end, and the slot positioned in alignment with one of the existing chords of said venetian blind assembly, each pitch adjuster with a plurality of teeth extending about the outer periphery of the slotted pitch adjuster, from proximity to the neck portion on the first end to a distal end;
• c) a screw gear positioned within the second aperture of each of the pitch adjustment housings, each screw gear with gear threads engaging the teeth on the pitch adjuster in a worm gear arrangement, each screw gear further having a multi-sided aperture extending through the screw gear in concentric alignment with the gear threads;
• d) a multi-sided rod slidably received through the multi-sided aperture in each of the screw gears located in each of the pitch adjustment housings;
• wherein rotation of the multi-sided rod provides a pitch adjustment of all the venetian blind slats located below the pitch adjustment housing.

A pitch adjustment apparatus for selective attachment to an existing vertical chord assembly of a Venetian blind apparatus, to selectively adjust the pitch of a plurality of slats located below the pitch adjustment apparatus, which comprises:

• a) at least two pitch adjustment housings, each with a first aperture and a second aperture positioned below the first aperture, the second aperture perpendicularly aligned in relation to the first aperture;
• b) a slotted pitch adjuster positioned within the first aperture of each of the pitch adjustment housings, each slotted pitch adjuster with a slot extending past a first end, the slot aligned with a neck portion extending about the outer periphery of the pitch adjuster near the first end, and positioned in alignment with one of the existing chords of said venetian blind assembly, each pitch adjuster with a plurality of teeth extending about the outer periphery of the slotted pitch adjuster, from proximity to the neck portion on the first end to a distal end;
• the slot in the pitch adjuster is sized to receive a vertical cord from the venetian blind assembly, and the cord is rotated about the neck portion in the pitch adjuster as the pitch adjuster is rotated by the rotation of the hexagontal rod;
• c) a screw gear positioned within the second aperture of each of the pitch adjustment housings, each screw gear with gear threads engaging the teeth on the pitch adjuster, each screw gear further having a hexagonal aperture extending through the screw gear in concentric alignment with the gear teeth;
• d) a hexagonal rod slidably received through the hexagonal aperture in each of the screw gears, the hexagonal rod extending through each of the screw gears located in each of the pitch adjustment housings;
• wherein rotation of the hexagonal rod provides a pitch adjustment of all the venetian blind slats located below the pitch adjustment housing.
