Abstract:
1. A mechanism for operating a blinds system comprising a head rail with operational tilt supports for at least four ladders, where at least two ladders each comprise a front rail, a rear rail, and transverse rungs, and where at least two of the ladder tilt supports are configured to support a first pair of the ladders, and at least two other ladder tilt supports are configured to support a second pair of the ladders, the mechanism such that the first pair is configured to be adjustable by user control relative to the second pair along at least one axis, such that first slats supported by the first pair of ladders would move relative to second slats supported by the second pair of ladders, where said relative movement is a translation in space along at least a horizontal or a vertical axis relative to the head rail, and where a tilting in-place motion does not itself constitute translation, and where vertical translation, if any, is accomplished by equal effective shortening and lengthening of the front and rear rails of the second pair of ladders where the upper termini of the left and right rails are fixed to a tilt barrel and have no freedom of vertical movement and the effective shortening and lengthening is accomplished by horizontal movement within the head rail of at least a portion of the front and the rear rails proximate to the tilt barrel.
