Abstract: A telescoping wand safely encloses the control ends of a set of lift cords of vertically raisable “blinds” (as defined in the specification). The wand includes a selectively releasable cord locking mechanism which cooperates with a lift cord tensioner and a cord locking mechanism in the blinds' headrail to allow a user to raise and lower the blinds by one-handed operation of the wand. The blinds are raised by reciprocatingly moving an outer handle tube telescopically along a stationary inner tube. Each time the handle is pumped up and down, the blinds are raised a discrete amount. The wand's cord locking mechanism allows the lift cords to slip through the wand on the handle's upward stroke, but grabs and pulls the lift cords on the handle's downward stroke. Two or three quick pumps of the handle are all that is typically needed to fully raise a set of blinds.
