Abstract:
1. A magnetic door sweep comprising: a door seal including a base member having a bellows elastically supporting a first magnet at an intermediate location below said base member, said first magnet having a first set of poles in which opposite poles are spaced apart at a first distance; and a threshold having a stationary threshold cap and a second magnet disposed beneath said stationary threshold cap, said second magnet having a second set of poles in which opposite poles are spaced apart at a second distance that is greater than said first distance; wherein said first set of poles are repelled from said second set of poles when said door seal is positioned away from said stationary threshold cap retracting said bellows upward from said intermediate location, and wherein said first set of poles are attracted to said second set of poles when said door seal is positioned proximate to said stationary threshold cap centering said first magnet over said second magnet and extending said bellows downward from said intermediate location such that said door seal engages said stationary threshold cap.
