String winding and unwinding apparatus
Embodiments of the present invention provide an apparatus for convenient tightening and loosening of strings such as those found in shoelaces of footwear. 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.
