ABSTRACT:
A cord retraction assembly for an electronic device includes a reel for winding and retracting the cord, a catch element adapted to engage the reel to prevent retraction of the cord, and an interlock for disabling the catch element when the cord is wound unto the reel. The catch element is urged into engagement with the reel by a spring to prevent retraction of the cord during use. A release button disengages the catch element from the reel, allowing the cord to retract. The interlock comprises a pivotally-mounted arm that rides over the cord as the cord accumulates on the reel. The accumulation of the cord on the reel pushes the arm outward into engagement with the catch element so as to prevent the catch element from moving back to the engaged position. As the cord is unwound from the reel, the catch element is able to return to the engaged position.
