APPARATUS FOR A BLIND

摘要

An approach is provided for an apparatus for a blind is disclosed that comprises a rolling module and a control module. The rolling module is located above multiple tapes vertically spaced by a ladder cord. The control module comprises an Epicyclic Gearing (EG) assembly, a tube, a spiral plunger, a universal joint and a control assembly. The tube has a guiding protrusion and a titter. The guiding protrusion is formed inside and bottom of the tube. The titter is configured for controlling the flipping of the tapes. The universal joint is connected between the EG assembly and the tube, and is configured for connecting the rolling module. The control assembly selectively moves up and down on the spiral plunger to rotate the tube. The rolling module raises and/or descends the tapes by the lifting cord according to the rotation of the tube.
