Filed:

Aug 19, 1981

Appl. No.:

6/294105

Inventors:

Sebastian Dittrich - Clifton NJ

Assignee:

Magnetic Weather Stripping Corp. - Clifton NJ

International Classification:

E06B 170

US Classification:

49470

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.

Abstract:

A threshold assembly for mounting on a door and a door sill is described which includes a threshold plate assembly formed of nonmagnetically attracted material and a door cap assembly for mounting on the bottom edge of the door. The threshold plate assembly has a first stepped portion with a substantially vertical face extending medially along the bottom edge of the door. This first stepped portion comprises: a riser portion and a stair portion extending from the lower edge of the riser portion inwardly toward and beyond the interior surface of a door. Second stepped portion on the bottom edge of a door includes the lowermost portion corresponding to stair portion of the first stepped portion and the uppermost portion corresponding to a saddle portion. A magnet mounting device for attachment to the lowermost portion of a second stepped portion includes: a slot extending substantially vertically adjacent the lowermost portion and a guard plate extending substantially horizontally adjacent the stair portion. A magnet holding assembly mounted to the magnet-mounting device that includes: a T-shaped mounting flange for mounting within a slot with the stem protruding therefrom; an extensible bellows attached at one end to the stem permitting the horizontally extending movement of the magnet assembly when magnetic attraction exists and horizontally retracting movement of the magnet assembly when magnet attraction ceases, and a pocket with one side attached at the other end of the extensible bellows.
