Magnetic door stop and door holder

A magnetic shunt assembly for adjustment of a force of magnetic attraction between the magnetic shunt assembly and an adjacent ferromagnetic structure, the magnetic shunt assembly comprising:

• a housing comprising a fixed top plate having an aperture disposed therein, the housing containing a rotatable base on which a plurality of magnets of different magnetic strengths are attached in proximity to the fixed top plate, wherein the rotatable base is configured to rotate within the housing with respect to the fixed top plate, wherein the force of magnetic attraction between the magnetic shunt assembly and the adjacent ferromagnetic structure is adjustable based on rotation of the rotatable base to select only one of the plurality of magnets to be aligned with the aperture in the top plate;
• or
• a housing containing a magnet fixedly attached to the housing, the housing including a rotatable top plate disposed in proximity to the magnet, the rotatable top plate configured to rotate with respect to the magnet, the rotatable top plate having a plurality of apertures of different sizes disposed therein, wherein the force of magnetic attraction between the magnetic shunt assembly and the adjacent ferromagnetic structure is adjustable based on selection of one of the plurality of apertures to be aligned with the magnet;
• or
• a housing containing a top plate in which an adjustable size iris aperture is centrally disposed, and a magnet fixedly attached to the housing in proximity to the top plate and in alignment with the adjustable size iris aperture, wherein a force of magnetic attraction between the magnetic shunt assembly and the adjacent ferromagnetic structure is adjustable based on adjusting the size of the adjustable size iris aperture.

A magnetic doorstop and door holder comprising:

• a hinge pin doorstop body having a first end and an opposing second end;
• a hinge pin receiving aperture disposed at the first end of the hinge pin doorstop body, the hinge pin receiving aperture configured to receive a hinge pin of a hinge of a door;
• a first leg having a proximal end and a distal end, the proximal end connected to the second end of the hinge pin doorstop body, and the distal end extending outward from the hinge pin doorstop body;
• an engagement member disposed at the second end of the hinge pin doorstop body adjacent the proximal end of the first leg;
• a second leg having a proximal end and a distal end, the proximal end adjustably received in the engagement member, and the distal end extending outward from the engagement member;
• a first bumper attached to the distal end of the first leg;
• a second bumper attached to the distal end of the second leg;
• a first magnet attached to the first bumper;
• a second magnet attached to the second bumper;
• a first ferromagnetic structure configured for attachment to the door, the first ferromagnetic structure comprising one or more materials that are magnetically attracted to the first magnet;
• and
• a second ferromagnetic structure configured for attachment to a door frame, door jamb, wall, or other entryway structure to which the hinge is attached, the second ferromagnetic structure comprising one or more materials that are magnetically attracted to the second magnet,
• wherein one or both of the first ferromagnetic structure and the second ferromagnetic structure comprise a magnetic shunt assembly that includes a housing containing a rotatable top plate in which a plurality of apertures of different sizes are disposed, and a third magnet fixedly attached to the housing in proximity to the rotatable top plate, wherein a force of magnetic attraction between the magnetic shunt assembly and the first or second magnet is adjustable based on selection of one of the plurality of apertures to be aligned with the third magnet.
