ABSTRACT:
To provide a highly functional yet very compact retractable reel assembly for a telephone extension cord, a housing is provided which is adapted to be mounted on a wall in proximity to a telephone or telephone jack for utilization with either wall mounted or table telephones, respectively. The retractable reel assembly includes a reel biased for rotation in one direction, a ratchet for selectively restraining rotation of the reel in the one direction, and an expansion chamber for a length of the cord within the housing, whereby the portion of the cord leading to the telephone or telephone jack can normally be wound in a radially and axially confined planar helical array. With this arrangement, the retractable reel assembly can allow the portion of the cord to be repositioned to a radially expanded helical array during withdrawal of the remainder of the cord from the housing and returned to the radially and axially confined helical array during retraction of the remainder of the cord into the housing.
