LADDER ROPE RETAINING DEVICE FOR VENETIAN BLIND
A ladder rope retaining device includes a support base, a rotating base, and an elastic positioning member. The support base has a bottom wall and two opposite straight walls connected with the bottom wall and each having a pivot trough. The rotating base includes a pivot pivotally disposed in the pivot troughs, and a ladder rope retaining portion formed on the pivot. The pivot has a plurality of positioning recesses arranged in an equally-spaced manner. The elastic positioning member is disposed to one of the straight walls of the support base and elastically engaged with one of the positioning recesses of the pivot. Thus, when the rotating base is rotated relative to the support base, the positioning recesses are alternately engaged with and disengaged from the elastic positioning member to generate a better operating feel.
