    Abstract: We disclose a cordless window blind that includes at least one electromagnet within each slat. The slats may be inserted into orifices within rotatable slat mounting members on a vertical guide rail assembly. The orifices may house electrical connections which connect the electromagnets to at least one battery. The electromagnets may have the same polarity such that the electromagnet of one slat attracts the electromagnet of an adjacent slat. The magnetic attraction may move one slat toward the other slat causing the slats to move vertically along the guide rail assembly and either raise or lower the blinds. Alternatively, electromagnets on only one of two longitudinal edges of the slats may be actuated and attract a metal member on an adjacent slat. The magnetic attraction may cause the slats to tilt and rotate within the slat mounting members thus closing the blinds.

    Abstract: Motorized window coverings are described herein. Various embodiments may include roll-up window shades, vertical blind slats, and/or horizontal blind slats. In one example, a motorized roll-up window shade is described. The shade includes a tube, a flexible panel, a fixed bracket, a rotatable bracket, bearings, a motor, and one or more batteries. The tube may have a longitudinal axis perpendicular to a transverse axis. The fixed bracket may include a first segment and a second segment connected to the tube and movably connected to the first segment. The rotatable bracket may include an articulating joint and may rotate the tube along the transverse axis. The bearings may enable rotation of the tube along the longitudinal axis. The motor and batteries may be disposed within the tube. The fixed bracket may include an opening through which the batteries may be accessed.

    Abstract: We disclose a headrail for window coverings that may include an extensible end cap and a gearbox which automatically adjusts the headrail mounting. The extensible end cap may include a mounting bracket which may be connected to a piston. The piston may be connected to a floating bearing. The gearbox may include a motor-driven main gear which rotates a threaded rod. As the threaded rod rotates, an end of the threaded rod may move toward a floating bearing. The floating bearing may apply force the piston which may transmit the force to the mounting bracket. The extensible end cap may also include a sensor which detects the amount of pressure or force applied to the mounting bracket. When the sensor collects a measurement below a defined level, the motor may actuate the main gear to rotate the threaded rod and apply additional force to the mounting bracket.

    Abstract: We disclose a window blind which includes at least one conformable seal which may inhibit light and/or heat transmission. The slats of the window blinds may include conformable seals on one or more of their edges. The conformable seals may include interlocking teeth, intermingled bristles, or a continuous strip of material which may form a lip. The window blinds may also include a conformable seal around an orifice through which a cord may be inserted. The conformable seal around the orifice may be designed similar to those of the slats or may include overlapping flaps of material. The slats may also include materials with different properties on either side of the slats. These may include light reflecting material and heat absorbing material.
