  • Patent number: 5530992
    Abstract: A hinge is described for use along each side of a refrigerator or on furniture to permit safe opening of the door or lid from either side. The hinge is uncomplicated in design, and is comprised of only a few component parts. Each hinge includes a hinge rod forming a swivel axis for the door, said rod held in an axle take-up receiver. At least one and preferably two interlocks are located at or near the top and bottom of each hinge rod. The interlocks comprise a hinge pick-up axially aligned with the swivel axis of the hinge and a hinge element which becomes mechanically coupled to the pick-up when the door is opened in the other direction. Details of the embodiments of the hinge are disclosed. Preferably, magnetic means are used to keep the hinge rod engaged with the swivel axis and to form the airtight seal between the door and the cabinet.

  • Patent number: 4788964
    Abstract: A smoke shield assembly for an over-the-range oven includes a magnetically hinged deflecting shield movable between stored and in use positions. The assembly includes a metal base secured to a forwardly positioned bottom metal member of the over-the-range oven by four magnets. Two of the magnets securing the base to the oven also form a magnetic hinge that secures the deflecting shield to the base. The two other magnets securing the base to the oven further maintain the deflecting shield in the stored position. The deflecting shield is metal having a generally U-shaped pivot end magnetically secured to the base. The pivot end may have an unhemmed pivot edge or a hemmed pivot edge to ease pivoting between the stored and in use positions.

  • Patent number: 4434524
    Abstract: Magnetic door hardware for closing swinging doors. Two magnets are axially aligned with the door post, and the magnetic fields of the magnets are aligned so as to produce a radial torque when the door is swung open. One magnet is attached to the door post, and the other magnet is attached to the door frame so that the radial torque produced by the magnets causes the door to rotate to the closed position.

  • Patent number: 4202574
    Abstract: This invention relates to a catch or lock mechanism used between a refuse or garbage can and the lid therefor. A substantially U-shaped bracket has the inner curve between its legs slidingly engaged with the undersurface of the lid bead carried by the lower edge of the lid. This may be by a threaded screw engaging with one leg of the U-shaped bracket and extending between the legs thereof to thereby form a sleeve sliding engaging the lid bead. Also, the U-shaped bracket may be movably carried by the U-shaped bracket or the can lid by the use of magnetic means. The U-shaped bracket preferably has a longer inner leg which is urged by spring or magnetic means into engagement under the bead at the top of the refuse can. The other leg of the U-shaped bracket is shorter and preferably terminates in an outwardly and horizontally extending portion for finger engagement thereof for releasing the lid from the can.

  • Patent number: 4122563
    Abstract: A hinged toilet seat and cover assembly has at least two magnetic latches positioned to control the movement of the seat and cover. A first magnetic latch positioned between the hinge and cover serves to hold the cover in a vertical position once the cover has been raised to such position. A second magnetic latch positioned between the cover and seat at a point spaced from the hinge serves to hold the cover and seat in contact with each other once they are brought into such contact.
