ABSTRACT:
An improved threshold assembly for mounting on a door and a door sill is described which includes a sill-mounted portion with a threshold plate formed of nonmagnetically attracted material and a door-mounted portion with a door cap for mounting on the bottom edge of the door with a flexible magnet-holding device. Two elongated magnets are mounted one in each portion of the threshold assembly, and, when the door is in the closed position, the magnets are positioned one on top of the other. The magnets are structured so that the opposite edges have opposite polarity and are mounted with adjacent magnet edges having unlike polarity. During closing of the door, the edges of like polarity approach and repel one another and causes the magnet-holding device to move away from the threshold plate.
