Abstract

PURPOSE:To allow the magnetically attracted surface to continuously hold the close contact condition without indicating any inclination thereof and eliminate a fear of adding the external force due to the effect of lever even in case the external force is applied in such a direction that the engagement units are mutually isolated, by forming a mounting plate to be fixed to the base plate in the shape like a saucer and allowing the magnetically attracted surface to the other unit to be inclined within a predetermined range through the swinging engagement of the one ferromagnetic plate with play to the mounting plate. CONSTITUTION:A mounting plate 11 formed like a soucer is isolately provided for fitting a ferromagnetic plate 6, an engaging edge collar or engaging protruded piece 11b is provided at the inside of upper edge of rising part of the mounting plate 11, and the ferromagnetic plate 6 is engaged with the edge collar, projecting piece 11b. Even in case the plate 6 is swingingly engaged with play to the mounting plate 11, the plate 6 is capable of continuously holding the close contact or magnetically attracted condition (a) if the base plate 8 fixed to the mounting plate 11 is inclined or opened. The magnetically attracted surface is not inclined against an inclination of the mounting base, namely the base plate 8, particularly against an external force in the direction for separating the engagement units.

ものである。[Detailed Description of the Invention] This invention provides a fastener using a water/permanent magnet, in which either the male member or the female member, particularly the member which can be attached to and detached from the permanent magnet, is placed within a predetermined width. This makes it possible to wear out the magnet and continuously maintain a more stable magnetic state.

而して、従前に於るこの種の永久磁石を使用した止具構
造に於ては、そのいずれも係合雄、雌具共に基原に対し
完全に密着した状態のものをし、極力基板とのガタッキ
を生じないように特に工夫が凝らされたものである。Therefore, in the conventional fastener structure using this type of permanent magnet, both the engaging male and female fittings are in a state of complete contact with the base, and as much as possible the substrate is Special efforts have been made to avoid any looseness.

である。However, such an attachment is difficult to apply when an external impact is applied to the base, especially when a force is applied in a direction that causes the base to peel off like a lever. It was torn off and was no longer essential as an engagement tool. This inconvenience is caused by the fact that the engagement is based on the magnetic attraction force of the magnet, that is, the separation of one end of the magnetic surface induces the disappearance of the engagement state of the entire group due to a decrease in the magnetic attraction force corresponding to the square of the distance. It is something.

としたものである。The present invention has been specially devised in view of the above-mentioned inconveniences, in which the mounting plate fixed to the base is shaped like an organ, and one ferromagnetic plate is oscillated on the mounting plate. The two fittings can be fitted loosely and the magnetically attached surface of the other fitting can be tilted within a certain limit.

しめたものである。That is, in the present invention, even when an external force is applied to the engaging tools in a direction that causes them to separate from each other, the magnetically attached surfaces themselves continue to be in close contact with each other without tilting in any way, and at least the lever effect is maintained. This eliminates any fear of external force being applied to the magnetically attached surface.

In the case where a ferromagnetic plate (4) for shielding is attached to the magnetic pole face opposite to (2), there is no need to encapsulate the magnetic pole end face again, and the case (3) is simply made into a cylindrical shape.

In other words, if the length corresponds to the length of the ferromagnetic rod (7) on the plate (8), and the length of the rod (7) is sufficient to reach the plate (2). There is no need to cut the rod (5), and if the rod (5) has a length that reaches the upper edge of the hole (1) a of the magnet (1), it is not necessary to cut the rod (5). The rod (7) -
It is something that is no longer needed.
