ABSTRACT:
A device for the manual operation of a blind, preferably a vertical blind, by way of a pull cord, which is pulled as a loop with a leading end and a return end by a slat carriage movable in a guide with a slat each arranged on them around their longitudinal axis. The cord is led in a rail which blocks access to a majority of the cord. The rail has channels extending in a longitudinal direction defining passages for the leading end portion and the return end portion of the pull cord. The section rail also defines access openings for providing access by an operator to grip and move the pull cord through the rail. The rest of the rail blocks access to the pull cord.
