发明名称 Magnetic clasp for jewelry
摘要 Magnetic clasps for securing the opposed ends of chains and other jewelry. Each clasp includes an arrangement for securing separable bodies by means of magnets that have been poled to present opposed surfaces of opposite magnetic polarities. In a first embodiment, disk-like magnets are received in channels of mating elongated body members of like configuration. End flanges of the elongated body members, in addition to the disk-like magnets, provide axial resistance to separation while the resultant magnetic force prevents separation in the transverse direction. In a second embodiment, disk-like magnets of divided polarities are seated at ends of mating bodies. A pin-and-slot locking mechanism is formed in the two bodies and the magnets are oriented relative thereto so that resultant repulsive magnetic forces force the two magnets into mating alignment when in the longitudinal slot for maximum magnetic holding force. In a third embodiment, magnetic disks are held side-by-side by holders within a split hemispherical housing.
