US Patent 9141086 Magnetic actuated attachment mechanisms for wearable devices

A band for a wearable device includes first and second band links. The first band link includes one or more magnetic pins and the second band link includes one or more magnets and one or more apertures. In a first position, the first and second band links mechanically and magnetically couple by the magnet pulling the magnetic pin into the aperture. In a second position, the first and second band links mechanically and magnetically decouple by the magnetic pin being forced from the aperture. In this way, the band links may be easily and quickly coupled to and/or decoupled from each other.
