Abstract
An improved controller for opening and closing a venetian blind vanes over a door or window opening. A pull cord is engaged with a pulley, which is moved with a loop cord selectively engaged with a cord lock attached to a handle. A rotatable switch in the cord lock is rotated, the cord lock grasps the loop cord, and the handle is moved downwardly to pull to loop cord. Such movement operates the pulley and pull cord to raise the blind vanes. When the cord lock is disengaged, the weight of the blind returns the components to the original position. A rotatable tilt switch or combination of rotatable tilt switches are attached to a tilt rod for selectively rotating the blind vanes. All cords are completely enclosed so that looped ends of the cords are not accessible to persons adjacent the window blind.
Claims20
An apparatus for moving horizontal vanes in a blind to shield an opening, comprising:
- a header having a housing with an upper end attached to said header and a lower end distal from said header;
- a continuous pull cord proximate to said header, wherein said pull cord is engaged with said vanes and is operable to selectively transport the vanes across the opening;
- a rotatable pulley engaged with said pull cord for moving said pull cord to transport the vanes;
- a continuous loop cord having an upper looped end engaged with said rotatable pulley and having a lower looped end;
- a handle engaged with the lower looped end of said continuous loop cord, wherein said handle is moveable relative to said housing;
- a cord lock for selective engagement with said loop cord and vertically moveable with said handle, wherein said cord lock is operable to grip said loop cord so that downward vertical movement of said handle pulls said loop cord, thereby moving said rotatable pulley to move said pull cord;
- and
- a rotatable switch attached to said cord lock for selectively engaging and disengaging said cord lock from said loop cord.

- a rotatable pulley engaged with said pull cord for moving said pull cord to transport the vanes;
- a continuous loop cord having an upper looped end engaged with said rotatable pulley and having a lower looped end;
- a handle engaged with the lower looped end of said continuous loop cord, wherein said handle is vertically moveable relative to said housing;
- a tilt mechanism for rotating said vanes about a longitudinal axis of each vane to close the blind, wherein said tilt mechanism includes a tilt controller proximate to said housing;
- a cord lock mechanism for selective engagement with said loop cord and vertically moveable with said handle, wherein said cord lock is operable to grip said loop cord so that downward movement of said handle pulls said loop cord, thereby moving said rotatable pulley to move said pull cord.
