Abstract
A bi-directional device includes a rotatable control handle, a first line, and a second line, each extending from a housing. When the control handle is rotated in a first rotational direction, at least a portion of the first line is drawn into the housing. When the control handle is rotated in a second rotational direction, opposite the first rotational direction, at least a portion of the second line is drawn into the housing. Optionally, the control handle is positionable into each of a drive position and a release position. The control handle is generally biased into the drive position by an elastic force such as that of a spring. While the control handle is at the drive position, those portions of the lines drawn into the housing by rotations of the control handle are prevented from being withdrawn. When the release position of the control handle is obtained, drawn portions of the lines can be withdrawn from the housing.
