ABSTRACT:
A tensioning device is to be used with a control cord of a blind assembly and includes a hollow casing which confines a vertically extending receiving space and which has an open top end portion and a bottom end provided with a pivot portion. A pivot unit mounts rotatably the pivot portion of the casing on a wall body. A cord engaging unit has a pulley formed with a cord engaging groove for passing over of the control cord, and a base slidably provided in the receiving space and having a front side formed with a pulley receiving recess. The pulley is mounted rotatably to the base in the pulley receiving recess. The base further has a top wall formed with a pair of notches which permit extension of parallel sections of the control cord that passes over the pulley. A cover member is mounted on the open top end portion of the casing, and is formed with a pair of slits that are aligned with the notches in the top wall of the base and that permit extension of the parallel sections of the control cord therethrough. A force generating member is provided in the receiving space and forces the base of the cord engaging unit downwardly in the casing in order to permit tensing of the control cord when the casing is mounted on the wall body.
