  • Patent number: 6082656
    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.

  • Patent number: 5246450
    Abstract: The present invention provides a means for applying a substantially constant force to move clips in queue within an applicator, as well as means for more effectively dispensing the endmost clip from a column of abrasive clips within an applicator. The constant force means generally comprises a constant force spring which is movably secured at both ends within a chamber in the applicator such that the pressure exerted between the ends of the constant force spring forces the clips in queue toward the jaws of the applicator. The dispensing means generally comprises a spring that applies sufficient pressure against the endmost clip in a column of abrasive clips to dispense the endmost clip from the column while preventing the next endmost clip from being dispensed until after the endmost clip has been forced into the jaws of the applicator and applied.
