Abstract
Abstract The present invention relates to a fastener means comprising an attracting member A with a permanent magnet 1 and an attracted member B with a ferromagnetic element 110 to be attracted by the former member. To assure easy and stable attraction between the members A and B when they are respectively fixed to a pair of objects C and C' disposed in an intersecting relation, the members A and B include planes and e' that are parallel to each other when the members are attracted. Alternatively, the main attraction surfaces a' and/or b' of the members A and B include a plane d and/or d' within a virtual plane D that intersects the fixing surfaces of the objects, or the attracting member A and/or the attracted member B are fixed to the object with an inclination, so that the members A and B can be held stably attracted to each other without being subject to external force.

A fastener means comprising an attracting member having a permanent magnet and an attracted member having a ferromagnetic element to be attracted by said attracting member, characterized in that the attracting and the attracted members are fixed to respective fixing surfaces of a pair of objects, wherein a separate tilting member is disposed between the attracting member and one of the fixing surfaces or between the attracted member and the other fixing surface.
Claim 6
Dependent Claim
73 words
A fastener means comprising an attracting member having a permanent magnet and an attracted member having a ferromagnetic element to be attracted by said attracting member, characterized in that the attracting and the attracted members are fixed to respective fixing surfaces of a pair of objects, wherein a separate tilting member is disposed between the attracting member and one of the fixing surfaces or between the attracted member and the other fixing surface.
Claim 7
Dependent Claim
119 words
The fastener means as claimed in any one of claim 1, 2, or 3 wherein: said attracting member comprises one magnetic polar surface on the side where it attracts the attracted member and the other magnetic polar surface on the side where it faces the object to which it is fixed, a permanent magnet with a hole that extends between said magnetic poles, and a second ferromagnetic element provided on the side of the magnetic pole where it faces the object to which the attracting member is to be attached; and the second ferromagnetic element of the attracting member and the ferromagnetic element of the attracted member are attracted to each other within said hole in the permanent magnet.
Claim 8
Dependent Claim
181 words
A fastener means comprising an attracting member having a permanent magnet and an attracted member having a ferromagnetic element to be attracted by said attracting member, wherein when the attracting member and the attracted member are respectively fixed to one of a pair of nonparallel objects, the attraction surfaces of the attracting member and the attracted member run parallel to each other when the attracting member and the attracted member are attracted to each other; and wherein said attracting member comprises one magnetic polar surface on the side where it attracts the attracted member and the other magnetic polar surface on the side where it faces the object to which it is fixed, a permanent magnet defining a hole extending between said magnetic poles, and a second ferromagnetic element provided on the side of the magnetic pole where it faces the object to which the attracting member is to be attached; and wherein said second ferromagnetic element of the attracting member and the ferromagnetic element of the attracted member are attracted to each other within said hole in the permanent magnet.
