Magnetic tilt mechanism for Venetian blinds

A tilt mechanism for use behind a pane of glass having an inner surface, and an outer surface the tilt mechanism comprising:

• a. a shaft having a threaded portion and to which shaft the tilt cords can be attached;
• b. a nut on the threaded portion of the shaft;
• c. a first magnet attached to the nut and positioned for placement adjacent the inner surface of the pane of glass;
• d. a slide having a second magnet positioned opposite the first magnet such that movement of the slide and second magnet in one direction moves the nut in that same direction causing the shaft to rotate in a clockwise direction and movement of the slide and second magnet in an opposite direction moves the nut in that opposite direction causing the shaft to rotate in a counterclockwise direction;
• e. at least two pairs of tilt cords attached to the shaft;
• and
• f. a bottom rail having
• i. an inside edge and an outside edge,
• ii. a pair of slots for each pair of tilt cords, the pair of slots comprised of an inside slot on the inside edge of the bottom rail and an outside slot on the outside edge of the bottom rail, and
• iii. at least one hole near each pair of slots wherein each pair of tilt cords passes through a pair of slots and through the at least one hole.

An improved window blind of the type having a headrail, a bottom rail, and a plurality of tilt cords extending from the headrail to the bottom rail wherein the improvement comprises a tilt mechanism comprising:

• a. a shaft positioned within the headrail and having a double helix threaded portion and portions to which the tilt cords can be attached;
• b. a nut on the threaded portion of the shaft;
• c. a first magnet attached to the nut and positioned for placement adjacent the inner surface of a pane of glass;
• and
• d. a slide having a second magnet positioned opposite the first magnet such that movement of the slide and second magnet in one direction moves the nut in that same direction causing the shaft to rotate in a clockwise direction and movement of the slide and second magnet in an opposite direction moves the nut in that opposite direction causing the shaft to rotate in a counterclockwise direction, wherein the slide is comprised of a generally rectangular housing having a slot and a tab projecting through the slot and attached to the second magnet, the tab projecting outwards from the housing such that the tab can be grasped manually and moved within the slot to move the second magnet with respect to the housing thereby causing the shaft to rotate an amount corresponding to a distance over which the tab is moved.

• ii. a pair of slots for each pair of tilt cords, the pair of slots comprised of an inside slot on the inside edge of the bottom rail and an outside slot on the outside edge of the bottom rail, and
• iii. at least one hole near each pair of slots wherein each pair of tilt cords passes through a pair of slots and through the at least one hole.

An improved double pane window of the type having a frame carrying a first pane of glass which has an inside surface and an outside surface, a second pane of glass and a window blind positioned between the panes of glass, the window blind having a headrail and a plurality of tilt cords wherein the improvement comprises a tilt mechanism comprising:

• a. a shaft positioned within the headrail and having a double helix threaded portion and portions to which the tilt cords can be attached;
• b. a nut on the threaded portion of the shaft;
• c. a first magnet attached to the nut and positioned for placement adjacent the inner surface of a pane of glass;
• and
• d. a slide having a second magnet positioned opposite the first magnet such that movement of the slide and second magnet in one direction moves the nut in that same direction causing the shaft to rotate in a clockwise direction and movement of the slide and second magnet in an opposite direction moves the nut in that opposite direction causing the shaft to rotate in a counterclockwise direction, wherein the slide is comprised of a generally rectangular housing having a slot and a tab projecting through the slot and attached to the second magnet, the tab projecting outwards from the housing such that the tab can be grasped manually and moved within the slot to move the second magnet with respect to the housing thereby causing the shaft to rotate an amount corresponding to a distance over which the tab is moved.
