    摘要： A magnetic lock device includes a first element and a second element that are capable of being detachably coupled together by attracting each other magnetically under the magnetic interaction of permanent magnets, wherein each of the first and second elements includes an annular permanent magnet having a center bore through it, a ferromagnetic disk-like plate disposed to make contact with the permanent magnet, and a ferromagnetic projecting member extending from the disk-like plate and through the center bore of the permanent magnet. All of the component parts for the first and second elements are covered with any suitable synthetic resin film, sheet or the like and shielded from the outside, so that any foreign matter such as dust, particularly ferromagnetic particles like iron, cannot enter the gap or space that is present between the outer peripheral wall of the projecting member and the inner peripheral wall of the center bore through the annular permanent magnet. In one specific form of the magnetic lock device, each of the first and second elements is entirely covered with any suitable non-magnetic, synthetic resin film, sheet, covering or casing, or is entirely covered with a coating of any suitable non-magnetic, synthetic resin layer. In another specific form, each of the first and second elements is covered with any suitable non-magnetic, synthetic resin film, sheet, covering or casing, or is covered with a coating of any suitable non-magnetic, synthetic resin layer, except for the ends of the ferromagnetic projecting members in the first and second elements engaging each other that remain uncovered or exposed. In both forms, each of the first and second elements includes an annular permanent magnet, wherein one annular permanent magnet has a given polarity (S or N) opposed to the polarity (N or S) of the other annular permanent magnet on the side on which the first and second elements are to engage each other.

    摘要： A magnetic lock device provides a powerful magnetic attraction by making full use of the magnetic lines of force provided by a permanent magnet without causing. A first part provides a magnetic attracting action, and a second part that is magnetically attracted by the first part. The first part includes a permanent magnet, a first ferromagnetic plate rigidly attached to one side of the permanent magnet, and a nonmagnetic enclosure for packaging the permanent magnet and the first ferromagnetic plate into one unit. The second part includes a second ferromagnetic plate detachably attached to the other side of the permanent magnet and has a ferromagnetic rod extending therefrom adapted to be inserted into center bores through the permanent magnet and enclosure for engaging the first ferromagnetic plate or its ferromagnetic rod. The magnetic lock device further includes an arrangement for enhancing the magnetism at the point where the first and/or second ferromagnetic plate(s) and the ferromagnetic rod(s) are connected for increasing the cross sectional area of the magnetic path.

    摘要： A magnet clasp comprising a stationary part and a movable part, the stationary part including a permanent magnet, ferromagnetic plates secured to the permanent magnet, a ferromagnetic pillar and a non-magnetic case and cover which encase and cover the permanent magnet and associated parts, while the movable part has a ferromagnetic plug adapted to received by a central hole of the stationary part. The magnetic attracting force acts between the permanent magnet and the ferromagnetic plug to firmly hold the stationary and movable parts only when the ferromagnetic plug is placed in the central hole of the stationary part, whereas, when the ferromagnetic plug is placed on other portions of the stationary part, no substantial magnetic attracting force is exerted.
