Abstract
A magnetic fastener having a female member with a slide plate which attracted by the permanent magnet of the male member. The slide plate engages with the male member and thereby restrains removal of the male member unless manually slid into disengagement. The female member has first and a second plates between which the slide plate is slideably inserted. So as to secure the first and second plates together, deformable catches are formed on one of the plates and indentions which receive the catches are formed on the other. When the catches of the one plate are inserted in the indented portions of the other and then deformed, the first and the second plates are firmly engaged to constitute a female frame of the fastener.
Claims14
A fastener means comprising
- a male member provided with a projection, said projection including a permanent magnet, and
- a female member which includes a female frame comprising a first and a second plate member, and a slide plate which is made of a ferromagnetic material, slideably inserted between said first and the second plate members and having a manual contact surface exposed so as to be manipulatable between a first and a second position rom the outside of the female frame, said first and the second plate members and the slide plate having communicating openings through which said projection of the male member is inserted, said projection to be inserted in the female member having a means for engaging said slide plate when said slide plate is in said first position, said means disengaging said slide plate when in said second position, said first position being urged by attraction between a peripheral edge of the opening of the slide plate and the projection, wherein
- one from among said first and second plates of the female frame includes deformable catches on each of two opposing sides of said one plate, and the other from among said first and second plates has on side edges thereof indented portions which receive said catches, and wherein
- said first plate and the second plate are firmly engaged by a deformation of said catches.
