Systems and methods for multi-section window blinds

A window blinds system, comprising:

• a set of slats comprising:
• a first section, a plurality of double slats within the first section, a second section below the first section, and a plurality of single slats within the second section;
• a first lift cord and a second lift cord, wherein the first lift cord and the second lift cord each are controllable for raising and lowering at least a portion of the window blinds system;
• a plurality of outer supporting cords, each outer supporting cord extending around a front side of the blinds system and a back side of the blinds system, such that an outer supporting cord front section and an outer supporting cord back section are provided;
• a plurality of inner supporting cords, each inner supporting cord extending around the front side of the blinds system and the back side of the blinds system, such that an inner supporting cord front section and an inner supporting cord back section are provided;
• a plurality of transverse cords, comprising:
• a plurality of upper transverse cords associated with the plurality of outer supporting cords, wherein each upper transverse cord is spaced evenly from a top end to a bottom end of the window blinds system between the outer supporting cord front section and the outer supporting cord back section;
• a plurality of lower transverse cords associated with the plurality of inner supporting cords, wherein each upper transverse cord is spaced evenly from the top end to a bottom end of the window blinds system between the inner supporting cord front section and the inner supporting cord back section;
• wherein pairs of transverse cords are provided by one upper transverse cord and one lower transverse cord alongside each other along the blinds system;
• wherein a maximum amount of space between the double slats is a double gap and a maximum amount of space between the single slats is a single gap when the windows blinds system is in a fully opened shading arrangement, and wherein the double gap is larger than the single gap;
• wherein the double gap is created between neighboring double slats, between the first section and the second section, and between the second section and the third section, by providing an empty pair of transverse cords not supporting any slat within the double gap;
• wherein the single gap is created between neighboring single slats by mounting single slats onto each pair of transverse cords within the second section with no empty pairs of transverse cords within the second section;
• wherein each double slat comprises a top double slat and a bottom double slat each arranged on a single pair of transverse cords such that the top double slat is supported by a single upper transverse cord, and the bottom double slat is supported by a single lower transverse cord;
• wherein each single slat is arranged on a single pair of transverse cords such that the single slat is supported by both the upper transverse cord and the lower transverse cord of the pair of transverse cords;
• wherein the window blinds system is configured to be positioned into a variety of shading arrangements by adjusting a tilt angle of the plurality of double slats and the plurality of single slats and by adjusting a distance between neighboring slats of the set of slats.

A method of providing a variety of shading arrangements using a window blinds system, the window blinds system comprising:

• a set of slats extending downwards from a headrail at a top end of the window blinds system, the set of slats comprising:
• a first section, a plurality of double slats within the first section, a second section below the first section, and a plurality of single slats within the second section;
• a controlling cord associated with shaft controlling elements;
• a plurality of outer supporting cords, each outer supporting cord extending around a front side of the blinds system and a back side of the blinds system, such that an outer supporting cord front section and an outer supporting cord back section are provided;
• a plurality of inner supporting cords, each inner supporting cord extending around the front side of the blinds system and the back side of the blinds system, such that an inner supporting cord front section and an inner supporting cord back section are provided;
• a plurality of transverse cords, comprising:
• a plurality of upper transverse cords associated with the plurality of outer supporting cords, wherein each upper transverse cord is spaced evenly from a top end to a bottom end of the window blinds system between the outer supporting cord front section and the outer supporting cord back section;
• a plurality of lower transverse cords associated with the plurality of inner supporting cords, wherein each upper transverse cord is spaced evenly from the top end to a bottom end of the window blinds system between the inner supporting cord front section and the inner supporting cord back section;
• wherein pairs of transverse cords are provided by one upper transverse cord and one lower transverse cord alongside each other along the blinds system;
• wherein a maximum amount of space between the double slats is a double gap and a maximum amount of space between the single slats is a single gap when the windows blinds system is in a fully opened shading arrangement, and wherein the double gap is larger than the single gap;
• wherein the double gap is created between neighboring double slats, between the first section and the second section, and between the second section and the third section, by providing an empty pair of transverse cords not supporting any slat within the double gap;
• wherein the single gap is created between neighboring single slats by mounting single slats onto each pair of transverse cords within the second section with no empty pairs of transverse cords within the second section;
• wherein each double slat comprises a top double slat and a bottom double slat each arranged on a single pair of transverse cords such that the top double slat is supported by a single upper transverse cord, and the bottom double slat is supported by a single lower transverse cord;
• wherein each single slat is arranged on a single pair of transverse cords such that the single slat is supported by both the upper transverse cord and the lower transverse cord of the pair of transverse cords;
• the method comprising:
• pulling the controlling cord in a first direction to adjust a tilt angle of the plurality of double slats and the plurality of single slats and to adjust a distance between neighboring slats of the set of slats.
