Abstract
A magnetic button having a first button member incorporating a magnet and a second button member incorporating a body made of ferromagnetic material. The first button member and the second button member are magnetically couplable and uncouplable by moving towards and away from each other, respectively, in a coupling direction. The permanent magnet is annular, and a central body made of ferromagnetic material is arranged in a cavity of the permanent annular magnet.
Claims17
A magnetic button comprising:
- a first button member comprising:
- first and second sides facing away from one another;
- an annular magnet defining a cavity therein and having a substantially planar face;
- a central body of ferromagnetic material disposed in the cavity and having a substantially planar face, the faces of the annular magnet and the central body being disposed in coplanar relation with one another at the first side of the first button member;
- and
- a housing defining a recess therein and including an alignment element bordering at least part of the recess along a periphery thereof, the alignment element defining an internal diameter of the recess and the recess opening outwardly at the first side of the first button member;
- a second button member comprising a body of ferromagnetic material and a portion having an external diameter, the internal diameter of the recess being smaller than the external diameter of the portion of the second button member;
- wherein the first button member and the second button member are magnetically couplable by moving the first button member and the second button member towards one another along a first coupling direction and into a coupled configuration so that the portion of the second button member is disposed in the recess of the first button member in the coupled configuration, and the first button member and the second button member are magnetically uncouplable by moving the first button member and the second button member along a second coupling direction opposite the first coupling direction and into an uncoupled configuration, the alignment element of the housing being configured to axially align the first and second button members at least during movement of the first button member and the second button member towards one another along the first coupling direction and into the coupled configuration, and the first side of the first button member faces the second button member in the coupled configuration such that the faces of the annular magnet and the central body face towards the second button member in the coupled configuration.
