A blind is arranged such that minimal force is required to rotate the tilt drum to tilt the slats from the fully open to the fully closed position and back, with each of the front and rear tilt cables sharing the load nearly equally throughout the entire path from the fully open to the fully closed position and back.

A window blind assembly to provide illumination to the interior of a room and to prevent sunlight from entering the room includes a multitude of the light emitting diode (LED) slats mounted in the window opening of a window frame and being rotatably connected to the window frame: a controller being embedded in the window blind assembly and configured to control the function of each row of the LED slats.

A blind cutting machine includes a cutting blade; a base disposed on a first side of the cutting blade; and a guide disposed on a second side of the cutting blade. The first side is opposite the second side. The guide is adjacent to the cutting blade. The guide is configured to direct cutoff material to a waste collection area. An assembly includes a first member that is rotatable. A second member is configured to limit an amount of rotation of the first member. An actuator is configured to move the second member to a location wherein the second member does not limit the amount of rotation of the first member. The first member is configured to prevent a hand of an operator from coming into contact with the cutting blade.

A daylighting film (1) according to an aspect of the present invention includes a first base (2) that has optical transparency, multiple daylighting units (3) which are formed on at least a first surface (2a) of the first base (2) and each of which has the optical transparency, an opening space (9) which is provided between each of the multiple daylighting units (3), and a mark (5) which is provided on at least any one of the first surface (2a) side of the first base (2) and the second surface (2b) side that is opposite in direction to the first surface (2a), and which indicates information relating a daylighting film (1).

A shade covering for a blind having a plurality of horizontal slats and at least one cord ladder configured to support the slats may generally include a plurality of attachment portions configured to be spaced apart from one another along a first direction of the shade covering. Each attachment portion may define an insertion slit. The shade covering may also include a plurality of shade portions extending between each adjacent pair of attachment portions. Moreover, the insertion slit may be defined through a rear end of each attachment portion such that an insertion end of the insertion slit is open at the rear end.

A device for forming a jalousie includes at least first and second louvres pivoting about a common axis between a position in which the two louvres overlap and a position of angular separation of the louvres about the common axis. Preferably, the first louvre is at least partly translucent and the second louvre is opaque.
