Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the disclosure of a simple mounting structure for a stopper, particularly a female stopper, using permanent magnetic red.

Therefore, when fixing a female stopper using this type of permanent magnet, especially as a stopping means for a board such as a handbag, it is customary to separately prepare a washer with leg pieces, and use a ferromagnetic material attached to the magnet. The permanent magnet is assembled integrally with the plate, and a mounting washer etc. having another engagement hole is placed on the other end surface of the board, and the legs of the previous washer are inserted into this and then bent and engaged. A pair of parts is required in addition to the ferromagnetic plate, and the structure of the parts used is complicated, requiring a lot of time and effort for pressing, etc. The assembly required a lot of hands, and as a result, the manufacturing cost was relatively high.

In addition, in the case of fastening by inserting and bending the washer leg pieces, the female fastener itself tends to come off easily when an external force is applied, especially when a tensile force is applied. It could not be used as a means of wearing clothes.

The present invention has been specially devised to address the disadvantages of the conventional locking structure for female fasteners using permanent magnets, and the number of parts is assembled to the minimum necessary. In addition, this assembly is said to have a simple structure of parts, and since it requires less effort to assemble, it is said to be cheap to produce and is guaranteed to be reliable. After being fixed, there is no risk of it coming off unless the attachment structure etc. is torn or damaged.

Further, by utilizing this mounting structure, it is possible to attach a decorative button, etc., in the dark, and it is possible to provide this type of special decorative fastening at a low cost.The present invention is thus made possible. In order to achieve appropriate and purposeful performance of magnetic properties, the main structure of the permanent magnet is fixed to one of the pole faces of a permanent magnet, with appropriate holes opening from one pole end face to the other pole end face. The ferromagnetic plate and another ferromagnetic plate detachably attached to the other magnetic pole surface are brought into contact with each other through the holes of the permanent magnet, and are fixed to the permanent magnet. The ferromagnetic plate to be mounted is connected and fixed to a mounting structure attached to the other end face of the board with a mounting rod passed through a suitable ring material board, and furthermore, such an invention is provided. Considerable design changes are planned in accordance with the gist of this invention.The details of the present invention will be explained below with reference to a typical embodiment shown in the drawings. A ferromagnetic permanent magnet is formed by drilling or assembling the retaining hole (1) a, and is a ferromagnetic member that serves as an engaging male tool that is magnetically and removably brought into contact with one magnetic pole surface of the magnet. Board (2
), and another ferromagnetic plate (3) is attached to the other magnetic pole surface so as to be integrated with the permanent magnet (1), and the ferromagnetic plates (2) and (3) A permanent magnet (
1) is made to come into contact with the magnet in a removable manner through the hole (1) a, and as an example of this contact, as shown in Figures 1 to 3, a ferromagnetic metal is used. (3) An engaging rod (2) a that protrudes from the ferromagnetic plate (2) in the male retaining tool without any magnetic rods etc. in the direction of the twisted hole (1) ■.
through the hole (1) a of the permanent magnet (1) to the plate (3) K
In the case where the length dimension is the same, as shown in Figures 4 to 6, from the plate (3) to the hole (1) a direction, the hole (1) is
There is a considerable magnetic gap 1 between the plate wall of a! A ferromagnetic protruding rod (3)a for abutment is provided so as to interpose the i (4), and a ferromagnetic plate (2) serving as a male holding tool is inserted through the hole of the permanent magnet (1). , a case in which an engaging rod (2) a with a length reaching the end face of this protruding rod (2) a is provided protrudingly, and a case in which a plate is provided as illustrated in FIGS. 7 to 9. (3) The protruding rod (3) a that is attached to the permanent magnet (1)
The other end face of the hole (1) a in the hole (1) a should be at the position □ or slightly protruding from this, and the periphery of the plate (2) which is to be the engagement tool should be erected in a dish-like manner and the engaging edge flange ( 2) A case is planned in which the magnet is engaged with the periphery of the permanent magnet (1), which is the female component.

Next, various methods have been proposed for attaching the ferromagnetic plate (3) to the permanent magnet (1), but basically there is one method of attaching the permanent magnet (1) to the plate (3). Fixation by adhesive (Fig. 2, Fig. 3, Fig. 5, Fig. 6, Fig. 8,
(Fig. 9) and fixation by a cover (5) made of a non-magnetic material that serves as a protective coating for the permanent magnet (1) (Fig. 1, Fig. 4, Fig. 7, Fig. 10 to 12). In the latter case, the cover (5) is usually made of brass and has a cylindrical shape with one end open, and the locking pieces (5) a~
(5) Protrude a, hold the locking piece (5), and hold the plate (
3) with a permanent magnet (
1) Hole (1) l in K is opened to communicate with K, and the opening edge is bent in the direction of the hole (1) a to form a retaining edge flange (5) b.

In addition, as shown in Figures 7 and 10, another strong fiber plate (6) is attached to the magnetic pole surface of the permanent magnet (1) that is removably abutted to the magnetic plate (2). It is also planned to fix this with a substantially cylindrical clip (5) made of a non-magnetic material. Even in this case, the lines of magnetic force did not leak to the outside, and damage to the magnetic recording portion of the magnetic tape or the like could be prevented.

As a means for fixing the female fastener having the above configuration to a mounting board (7) such as a node link, the board (7) is used.
A mounting plate (8) is attached to the other end surface of the mounting plate (8).

9).

Various types of rods (9) are planned to be used as a means of this connection, but basically the rods (9) protrude from the ferromagnetic plate (3) (see Figure 2). Figure 12)
It is planned that the rod (9) will be protruding from the direction of the scattering rice (8) (as shown in the diagram), and in both cases, the rod (9) will be installed at the plate (8)%.
When provided integrally with (3), i.e. protruding rod (9)
(Fig. 3, Fig. 4, Fig. 6, Fig. 9, Fig. 12) and cases where it is a separate so-called insertion rod (9) (Fig. 1, Fig. 2, Figure 5, Figure 7, Figure 8, Figure 10, Figure 10-
Furthermore, in the relationship between this rod (9) and the ferromagnetic protruding rod (3) a, there is a difference between this rod (9) and this rod (3).
) a is integrated with plate (3) (Fig. 4,
Figure 9), when only the rod (3)a and rod (9) are integrated (IK Figure 5, Figure 7, Figure 10, Figure 10-), and when the rod (9) is integrated.
) is integrated with the plate (3) without relation to the rod (3) a (Fig. 6), and when it is made independent without relation to the rod (3) 1 or plate (3) K (Figure 6). There are various configurations such as (Fig.

Next, the aspect of the rod (9) is the so-called A in Figure 13.
There are various types of knock-bottle-shaped books, such as the knock-bottle-shaped book shown in , the stepped pin-shaped book shown in ``B'', the screw-rod-shaped book shown in ``C'', and the tapered stepped pin-shaped book shown in ``C''. In both cases, it was effective as a press-fit fastening rod.

Therefore, the rod is attached to one of the ferromagnetic plate (3) or the mounting plate (8), that is, the plate (3) or (8) which is to be subjected to the piercing pressure S attachment of the rod (9). (9) The piercing hole (s
) b s (s) ” and cut the puncture hole (a) b % (s) a as appropriate from #I (8) b
Cut this cut #1I(8)b~(8) so that
The end face of the plate (8) defined by b is used as an elastic piece to snap into a rod (9) inserted therein, and in particular to bite into the rod (9). (Please note that plate (3) is not shown in the illustration.) However, in order to improve the bite,
Cut the part defined by #(8)b to (8)b with the rod (9
) should also be made to bulge out in the opposite direction to the direction of insertion, which should be especially considered in the sense that this ensures ease of insertion and good bite. This is what I did.

The present invention has a characteristic structure on the ridge, in particular, the plates (3) and (8) are attached through the intermediate plate (7), and the opposed plates (3) and (8) are attached to the rod. (9) By using a simple method called piercing fastening to securely fasten, the above-mentioned characteristics II are achieved, especially the reduction in manufacturing costs, the reduction of labor for assembly, and reliable fastening. In addition, as shown in Figures 10 to 13, if a decorative button is provided in advance so that the mounting plate (8) can be turned over, this decorative button (
It also has the feature that it can be immediately attached to the
