  • Automatic base seal
    Patent number: 4283884
    Abstract: An automatic base seal for a door where a deformable rod having an end fixed in a molding deforms transversely through a slot when its other free end is engaged by a door frame when the door is closed. The deformed portion of the rod displaces a seal against the threshold to seal the bottom of the door. Sides of a groove in the molding guide the deformed portion of the rod, and return springs maintain the seal retracted and adjacent the slot when the door is open. In one embodiment the seal pivots, and in another embodiment the seal moves vertically.
