Lift cord tensioning device |
摘要 |
A lift cord tensioning device is provided for use with a window covering having at least one lift cord that extends downward though a shade portion from a head rail to a bottom rail. In one embodiment of the present invention, the tensioning device includes a pliable material having an aperture through which the lift cord extends. The aperture is sized to yieldably resist passage of the lift cord such that tension remains on the portion of the lift cord that resides in the head rail even when an upward directed force is applied to the bottom rail. In an alternate embodiment of the present invention, the tensioning device includes a pair of laterally offset holes through which the lift cord extends. In another alternate embodiment of the present invention, the tensioning device includes a resiliently biased gate through which the lift cord extends.
