Abstract
A magnetic snap fastener for releasably coupling a first material to a second material. The fastener includes a first fastening assembly affixable to the first material, and disposed in a first water-resistant enclosure. The fastener includes in one embodiment a second fastening assembly affixable to the second material. The first and second fastening assemblies each include a ferromagnetic eyelet having an integrally formed flange and protrusion magnetically coupled to a toroidal-shaped magnet. Alternatively, the second fastening assembly is a ferromagnetic cap or button. The first and second fastening assemblies provide magnetic coupling to releasably couple the first and second materials.
Claims10
A magnetic snap fastener for releasably coupling a first material to a second material, the fastener comprising:
- a first fastening assembly affixable to the first material, the first fastening assembly comprising a first ferromagnetic eyelet having an integrally formed flange and a hollow protrusion magnetically coupled to a first toroidal-shaped magnet such that the hollow protrusion of the first ferromagnetic eyelet is received in a center channel of the first toroidal-shaped magnet and an outer end of the hollow protrusion is substantially flush with a surface of the first toroidal-shaped magnet, the first fastening assembly disposed in a water-resistant enclosure;
- and
- a second fastening assembly affixable to the second material, the second fastening assembly comprising a ferromagnetic material, the second fastening assembly not being disposed is a water-resistant closure;
- the first and second fastening assemblies providing magnetic coupling to releasably couple the first and second materials.
A magnetic snap fastener assembly for releasably coupling a first material to a second material, the fastener comprising:
- a first fastening assembly affixable to the first material, the first fastening assembly including a base plate and a magnet on one surface of the base plate, the first fastening assembly disposed in a water-resistant enclosure;
- and
- a second fastening assembly affixable to the second material, and composed of a ferromagnetic material, the second fastening assembly not being disposed in a water-resistant enclosure;
- the first and second fastening assemblies providing magnetic coupling to releasably couple the first and second materials;
- wherein the magnet is toroidal in shape and the base plate comprises a hollow protrusion which is receivable in a center channel of the toroidal-shaped magnet.
