发明名称 Telephone cord straightener
摘要 A free-floating anchor sleeve is positioned on a telephone cord between the base unit and handset of a telephone. The weight of the straightener causes it to always find the low spot in the cord and thereby keep tension on each of the lengths of cord thereby keeping them separated and untangled. The straightener may be cylindrical or multi-sided in shape.
