Abstract
The quick release device may comprise a shade tube, a gear wheel engaging with the shade tube, a pawl removably engaging with the gear wheel and a solenoid configured to activate the pawl. The activation of the pawl disengages the pawl from the pawl wheel and allows the shade tube to rotate. The quick release device may also include a shade tube, a rotating brake plate engaging with the shade tube, a spring configured to apply pressure to the rotating brake plate and a magnet configured to apply magnetism to the spring. In response to the magnet applying magnetism to the spring, the spring contracts and releases pressure on the rotating brake plate and allows the shade tube to rotate.
