Claim of US Patent No. 10,772,223

1. A cable retractor, comprising:a retractor enclosure having an upper end and a lower end, and including a back surface having a length;
a retractor enclosure cover having a first interior surface;
a first enclosure cable pulley guide rail secured to said back surface along the length of the back surface, wherein first enclosure cable pulley guide rail provides a groove that extends along at least a portion of said length of the back surface;
a second enclosure cable pulley guide rail secured along the length of said first interior surface, wherein said second enclosure cable pulley guide rail provides a groove that extends along at least a portion of said first interior surface;
a cable pulley that is rotatable about a pivot configured to translate along the grooves provided by said first enclosure cable pulley guide rail and said second enclosure cable pulley guide rail;
a pulley rotational dampener guide block;
a pulley rotational dampener secured to said pulley rotational dampener for mechanically engaging said cable pulley and thereby dampen rotation of said cable pulley about its axis; and
a gravity retractor cable having an intermediate section secured to said upper end of said retractor enclosure, a second portion disposed along an edge of said retractor enclosure towards the lower end of said retractor enclosure, a third portion that winds down underneath and around said cable pulley, a fourth portion disposed along the edge of said retractor enclosure towards the upper end of said retractor enclosure, and an extracted portion having a cable end plug that extends outside of said retractor enclosure from said upper end, such that pulling the end portion of the cable away from said retractor enclosure urges said cable pulley upward along enclosure cable pulley guide rails toward the upper end of enclosure cable pulley guide rail, thereby reducing the lengths of the second and fourth portions of the cable and increasing the length of said extracted portion of the cable;
wherein upon termination of the pulling of the cable, bending and friction of the cable prevent movement of the pulley, and upon reducing the bending and friction of the cable, the gravitational weight of said pulley causes the pulley to move downward along said grooves toward the lower end of said retractor enclosure, thereby increasing the lengths of the second and fourth portions of the cable and reducing the length of the end portion of the cable.
