Abstract
PURPOSE: To increase adsorbing force, by fixing magnetic flux, which magnetically shapes a closed circuit when adsorption, to the movable portion side of a yoke passed through a flank of an outer circumferential portion of a magnet, in a magnet type latch used for a briefcase, other personal ornaments, etc.
CONSTITUTION: A magnet 1 in rare earth metal cobalt is used as a magnet material, and a main body portion is formed in such a manner that the magnet is cylindrically worked and a yoke 3 is adherence fixed to the back while the front is covered with a non-magnetic cover 2. Meanwhile, the desired magnet type latch is produced by fixing a center yoke 4 for passing magnetic flux, which magnetically shapes a closed circuit when adsorption, through a flank of an outer circumferential surface of the magnet 1 to a front of an adsorbing plate 5 in a movable portion. Latches 6 are each fixed to the backs of said yoke 3 and the adsorbing plate 5. Such an arrangement can obtain sufficient adsorbing force, and can produce small-sized and thin latches.
