초록 ▼

A magnetic seal is disclosed for releasably sealing two doors arranged side by side on a thermally insulated cabinet such as a refrigerator or freezer. A retainer gasket is affixed to the inner edge of each door. One of the retainer gasket encloses a magnet and retains the magnet fixed in place relative to the door. Another retainer gasket is affixed to the other door and is formed of a base, a sleeve enclosing a second magnet, and two flexible webs connecting the sleeve to the base. The retainer gaskets and magnets are arranged so that the magnets impart an attractive force on each other and releasably seal the doors. When one of the doors is opened slightly, the magnets are arranged to repel each other and assist in easily opening at least one of the doors. Finally, a magnet having more than two magnetic poles may be used to assist in sealing and opening at least one of the doors.

대표청구항 ▼

A magnetic seal for releasably sealing a first and second door, said doors each being mounted to a thermally insulated cabinet by a first and second hinge for movement between a closed position and an open position, comprising: a first retainer gasket extending in a lateral and longitudinal direction being affixed to said first door and enclosing a first magnet extending in said longitudinal direction, said first magnet being surrounded by said first retainer gasket, said first retainer gasket and said first magnet being affixed in a stationary position relative to said first door; a second retainer gasket extending in said lateral and longitudinal directions being affixed to said second door and having a sleeve surrounding a longitudinally extending said second magnet and a laterally extending base portion, said sleeve being mounted to said base by first and second flexible webs so as to allow said sleeve to move in a transverse direction; said retainer gaskets and magnets being arranged in opposing and proximate relationship when said doors are in said closed position, said retainer gaskets and magnets being spaced apart when said doors are in said open position; said first and second magnets being arranged so as to impose an attracting force on each other and thereby to move said second magnet transversely toward said first magnet when said doors are in said closed position, thereby releasably sealing said door in said closed position; and said magnets being arranged so as to impose substantially no force on each other when said doors are in said open position and so as to impose a repelling force on each other and to move said second magnet transversely inward toward said second door when said first door in said closed position and said second door is an intermediate position between said closed and said open position.
