Abstract
A blind which includes: a rectangular frame; windows fit on the front and rear surfaces of the frame; a slat part embedded in between the windows mounted on the front and rear surfaces of the frame; an upper movable part and drum parts mounted on a back headrail half and a front headrail half of the upper portion of the frame to control the slat part; a side movable part inserted into a side guiderail of a side of the frame; and pull cords connected to the slat part, the drum parts, the side movable part, and corner keys for controlling opening and closing of the blind.
Claims28
A blind comprising:
- a rectangular frame;
- comprising a front surface and a back surface and at least one side guiderail;
- a front window attached to the front surface of the frame;
- a back window attached to the back surface of the frame;
- a slat part comprising one or more slats and a bottom rail wherein the one or more slats and the bottom rail are operatively connected to the frame;
- an upper movable part comprising one or more drum parts and a helical gear part installed within the frame, wherein the helical gear part is coupled to a front tilting mechanism mounted externally on the frame for controlling a tilt angle of the slats;
- and
- a side movable part installed within the side guiderail for opening and closing the slat part, the side movable part comprising
- an up-down handle coupled to the side movable part and mounted externally on the frame for movement along a length of the side guiderail to raise or lower the slat part, wherein a total distance required to move the up-down handle to completely raise or lower the slat part is a fraction of the length of the side guiderail, wherein the up down handle need only be moved ⅕ the length of the side guide rail to completely raise or lower the blind.
