Patent abstract
An apparatus for convenient tightening and loosening of strings such as those found in shoelaces of footwear is provided. The apparatus includes a rotating portion within a base portion. A cover portion, when operated in a first position, provides a ratchet movement that allows rotation in a tightening direction while preventing movement in a loosening direction. When the cover is moved to a second position, the ratchet mechanism disengages, and the strings can then be easily loosened.
