  • Patent number: 10309152
    Abstract: A control assembly for a roller blind, the assembly including a chain wheel adapted to be driven by an operating chain; a drive bush; and a locking pin, wherein at least one of the chain wheel and drive bush includes a coupling element which in use couples the chain wheel to the drive bush such that axial displacement of the drive bush results in a corresponding axial displacement of the chain wheel, but that relative rotational displacement between the chain wheel and the drive bush is permitted through an arc defined between a pair of opposed stops which are carried by the other of the chain wheel and the drive bush; and wherein the locking pin passes axially through the chain wheel and the drive bush, the locking pin including at one end thereof a pair of opposed legs and at least one leg includes a locking lug adapted to engage a stop surface of the drive bush.

  • Patent number: 8763676
    Abstract: The present invention relates to a roller blind idle end assembly for roller blinds comprising a splined bush, a support bearing and an end pin, wherein the splined bush is supported by the support bearing and rotatable relative thereto in use; the end pin projects from the support bearing and is slidably coupled thereto such that the end pin is adapted to move axially relative to the support bearing and projects therefrom to engage with a receiving element of a mounting bracket; and wherein the end pin is rotationally fixed relative to the support bearing. This assembly reduces wear between an idle end pin and an idle end bracket and the likelihood of failure of the blind.
