Abstract
PURPOSE: To eliminate locational displacements in the location of attraction and to strengthen the forces of attraction by providing a female device with a concave spherical magnetic pole surface and a male device with a convex spherical ferromagnetic plate and oscillation-freely constituting either device. CONSTITUTION: A door catcher is formed of a female device A and a male device B. The female device A is formed of a permanent magnet 1 with a hole 1a and a concave spherical magnetic pole surface (b), a ferromagnetic plate 2 which is attached to a magnetic pole surface (a) and from which a ferromagnetic protrusion 2a is protruded, and a non-magnetic case 4 formed in the shape of a turned dish with a hole 4a connected to the hole 1a. The male device B is formed of a convex spherical ferromagnetic plate 3. Then the devices A and B are each mounted to either a door stop C or a door, for example, the female device A to the door stop C, and the male device B to the door. Then the female device A is constituted so as to be freely retracted and oscillated in a tubular part 5 via a washer, a nut, etc. By this, it is possible to bring both spherical attracting surfaces into strong attraction by oscillation without the need for special accuracy in mounting.
