Abstract
A mechanism for storing a length of cord that includes a first and second pair of pulleys mounted at opposite ends of a frame. An intermediate section of a cord is stored in the frame and has one end of the stored section fixed to the frame, with the other end extending from the frame. The stored cord section is at least partially wound over the pair of pulleys, and one pair of pulleys is slidably mounted for motion toward the other pair of pulleys. A damper is coupled to one of the second pair of pulleys, which engages the pulley to rotate about an axis to damp the rotary motion of one of the second pair of pulleys in such a manner that the intermediate storage section is in tension during retraction and withdrawal. The mechanism further includes a solenoid that is activated locally or remotely by a switch.
