Abstract

A cord separator used in a blind cord winding mechanism is disclosed to include a support portion, two wing portions respectively and outwardly extended from two opposite lateral sides of the support portion and respectively defining therein a cord insertion hole for the passing of one respective transmission cord, and two extension portions respectively perpendicularly extended from the wing portions along the axial direction of the cord insertion holes in parallel manner and respectively terminating in a positioning end portion for hooking on one respective side post of the blind cord winding mechanism so that the cord separator is capable of separating two transmission cords of the blind cord winding mechanism and preventing the two transmission cords from interfering with each other or being tangled during transmission.

Claims

1. A cord separator used in a blind cord winding mechanism, comprising a support portion, two wing portions and two extension portions, said two wing portions being respectively and outwardly extended from two opposite lateral sides of said support portion, each said wing portion defining therein a cord insertion hole, said extension portions being respectively perpendicularly extended from said wing portions along the axial direction of said cord insertion holes in parallel manner and respectively terminating in a positioning end portion.

2. The cord separator as claimed in claim 1, wherein said support portion is an elongated member;

said two wing portions are respectively extended from said support portion at different elevations and disposed in rotational symmetry along with a long axis of said support portion.

3. The cord separator as claimed in claim 1, wherein said support portion has an arched cross section.

4. The cord separator as claimed in claim 1, wherein said two cord insertion holes are disposed at different elevations.
