The present invention relates to a mechanism for automatic opening of rolling doors (20) in case of emergency consists of: a roller (21) that is a hollow round roller and has at least one first locating hole (211) which is formed at an one end of the roller; a rotation axis (22) has a diameter smaller than the diameter of the roller (21) and coaxial rotatable inside the roller (21) and has two rotation ends (222) outside of the roller; at least one spring (24) has an one end (241) fixed to the rotation axis (22) and the other end (242) is fixed to the internal surface of the roller (21), when the rotation axis (22) rotates relatively against the roller (21) in the opposite direction of the rolling door body so that, when convoluted spring (24) generates elastic accumulated energy of spring (24); an elastic accumulated energy fixing unit (25) that is placed on a rotation end (222) of the rotation axis (21) and has a first locating hole (211) of the roller (21) to fix elastic accumulated energy; and an activator (26) activates to release elastic accumulated energy, thereby it produces the efficiency of automatic opening of the rolling door.

Methods and apparatus to control architectural opening covering assemblies are disclosed herein. An architectural covering assembly including an architectural covering; a tube to which the architectural covering is coupled; a manual controller operatively coupled to the tube to rotate the tube; a motor including a motor housing and a motor shaft; and a clutch assembly including a clutch and a clutch housing in which the clutch is disposed, the motor shaft coupled to the clutch and the clutch coupled to the manual controller to hold the motor shaft substantially stationary when the architectural covering is moved under an influence of the motor to cause the motor housing to rotate with the clutch housing and the tube.

A motor-operated drive system for a window covering system including a headrail, a mechanism associated with the headrail to spread and retract the window covering, and a continuous cord loop extending below the headrail for actuating the mechanism to spread and retract the window covering. The drive system includes a motor, a driven wheel that engages and advances the continuous cord loop, and a coupling mechanism for coupling the driven wheel to a rotating output shaft of the motor for rotation of the driven wheel. The drive system includes a channel system for redirecting the continuous cord loop engaged by the driven wheel, or other mechanism for configuring the drive system so that continuous cord loop extends in a substantially vertical orientation. The coupling mechanism includes an engaged configuration in which rotation of the output shaft of the motor causes rotation of the driven wheel, and a disengaged configuration.

Present disclosure relates to several adjustable roller shades. Adjustable roller shade includes: roller shade fabric winding shaft, weight, movable pulley, loop traction rope, two winders and two tensioning wheels. A roller shade fabric is wound on roller shade fabric winding shaft forming upper edge of adjustable roller shade. Weight is attached to bottom of roller shade fabric forming lower edge of adjustable roller shade. Movable pulley is fixedly attached to one end of the roller shade fabric winding shaft. Loop traction rope is wound around the movable pulley, two winders and two tensioning wheels. One or more driving motors drive the pair of winders to rotate in different combination of directions to raise or lower both upper edge and lower edge of adjustable roller shade, resulting the adjustable roller shade to be opened or closed freely from both upper and lower edges of the adjustable roller shade.
