Abstract

PURPOSE:To obtain a flat magnetically attaching end surface as well as permit an engaging means to be excellently attached to clothes or the like, by pressing a ferromagnetic plate constituting a male member of the engaging means so as to simultaneously form notches and tabs in addition to a rod part, and bending the plate by utilizing the notches. CONSTITUTION:A non-magnetic case 4 has a collar 4b communicating with a bore 1a in a permanent magnet 1 and abutting against the end of the bore 1a, and a tab 4a at its opened end, thereby to attach the magnet 1 and a ferromagnetic plate 2 to each other. A male member mating with this female member is shaped by pressing a ferromagnetic plate 3 to simulataneously form a rod 3a, a bent part 3c and notches 3b as well as tabs 3d on both side edges. If the plate 3 is bent by utilizing the notches 3b, it is possible to easily obtain a flat end surface which magnetically attaches to the female member, and the male member is excellently attached to clothes (x) or the like through the tabs 3d. According to this constitution, the ferromagnetic plate 3 is reduced in forming cost, and bending and attaching are made easy and reliable.

Description

[Detailed Description of the Invention] This invention relates to the modification of a male stopper in a retainer using a permanent magnet, and to the disclosure of a retainer structure that is particularly easy to manufacture and has good sprayability. .

Therefore, the engaging male stopper in this type of retainer using a permanent magnet is usually in the shape of a flat plate, which requires a lot of work and effort to bend and fasten. This has the disadvantage that the bent end is not necessarily straight.

Inconveniences in the surface of such a mating male stop often reduce the magnetic adhesion to the magnetic pole face of the female stop;
This is because the so-called magnetic abutment surface has looseness.

The engaging tool according to the present invention was specially devised in view of the inconvenience in the conventional example of force 1, and the engaging tool has a notch in the ferromagnetic plate (3). When attaching the mounting plate (3) to a handbag, clothes, band, etc., the folding can be done at the cutout +31b part, and this improves the ability to prevent the application from being applied. A permanent magnet (1) whose magnetically attached end face is particularly a flat f# square face, and a hole (1)a is opened from one magnetic i face to the other magnetic pole face.
The ferromagnetic plate (2) is fixedly attached to one magnetic pole surface in the magnetic pole surface, and the ferromagnetic plate (2) is made to come into contact with the other magnetic pole surface in a removable manner.
+ A ferromagnetic rod (3) a protruding from the plate (3) is inserted into the hole (1
)a, the mounting plate ( The magnetically attached end face of 3) is located laterally so that notches (3) b are provided from both sides of the iron plate (3), and the plate (3) is placed at the position of the notches (3) b.
) is designed so that the tip part can be bent through the edge of the board, and the following specific examples and considerable design changes accompanying these examples are planned. .

The following is a typical example of the present invention: 51Ii! ：Example 2 To explain the engagement tool shown in the attached drawing, (1) is a ferrite magnet or the like in which a hole (1) a is opened from one of the magnetic pole faces to the other magnetic pole face. Various types of magnets such as compacted magnets, steel bar magnets, plastic magnets, or rare earth magnets are used especially when the suction force is to be chained, and the ferromagnetic plate (2) is fixed to one of the magnetic pole faces. At the same time, a ferromagnetic plate (3) is magnetically and removably brought into contact with the other magnetic pole surface, and a ferromagnetic rod (3) a protruding from the plate (3) is inserted into the plate (2) through the hole (1) a. Alternatively, the rod (2) a protrudes from the plate (2) and is brought into contact with the rod (2) a in a removable manner.

In addition, the magnet (1) has a case made of irrational material! ii.It is integrally wrapped and fixed with 121, communicates with the hole (1)a, has a flange +41b that engages the end of the chain hole (1)a, and has an open end. #1 small nail +
4) With a and C, the magnet +1) and the plate (2) can be easily fitted and fixed, and the magnet (1) can be placed in the center position.

One engaging female stop is engaged while the other male stop is a plate (3).
A rod (3) a is provided protrudingly on the surface, and its small diameter ring is caulked 13.
1a' and integrated with the plate (3), and the mounting plate (3) is extended laterally to form a folded plate part (3)C, and this folded plate part (3)C and the original A cutout (3) 6% + 31 b is provided inward from the edges between the magnetically attached end faces, and the cutout (3) b is formed along the line of (3) b.
It is designed so that it can be bent and fixed.

Also, when attaching the plate (3) by bending it, the claws (3) d should be attached to the plate (3) in order to improve the adhesion to the foil plate X, etc.
It is designed to be provided along both side edges of the.

In the structure of the rice bowl (3), the forming of the plate (3) is completed in one step by simple press forming, and then the rod (3) is formed.
This is the caulking of plate (3).
The molding cost was considered to be low.

In addition, the presence of the notch (3)b in the plate (3) makes the bending of the plate (3) extremely easy, and the bending edge becomes straight. As a result, the magnetically attached end surface with the engaging female stopper could be provided as a particularly smooth end surface.

The embodiment shown in Fig. 5 is an example in which the rod (3) a has a length that reaches the plate (2) and the rod (2) a is omitted, and the embodiment shown in Fig. 6 is an example in which the rod (2) a is omitted. A ferromagnetic plate (6) is placed on the magnetic pole surface of the magnet (1), and the ferromagnetic plate (6) is emitted from the magnetic pole surface! ′! It is designed to capture the magnetic lines of force and produce the desired magnetic shielding effect, and the embodiment shown in FIG.
) Case (4) for the purpose of increasing the magnetic shielding effect of
Raise the area around the end surface that contacts the plate (3) at the shoulder (
4) It has a C8 configuration and is designed to prevent the magnetic tape etc. from coming into contact with the i-contact pole surface.

Further, the embodiment shown in FIG. 8 shows an example in which the case (4) is simplified to have a cylindrical shape, and the upper surface of the magnet (1) is covered with a magnet (Iida).

In the embodiment shown in Fig. 49, case (4) in the above example is omitted and plates (2), (6) and magnet (1) are replaced with -
The example shown in Figure 10 does not include the use of the plate (6), and is a plastic magnet with good impact resistance. etc. were used.

In addition, when attaching these female fasteners to a handbag, clothes, band, etc., it is customary to use the legs (5).
a, +5) It is planned to use an intervening device such as a washer (5) with a, but the engagement tool may be directly attached with double-sided adhesive tape, or screws, bolts, pins, eyelets, etc. Attachment to the board X by means of tubes, explosion welding, soldering, etc. is separately planned.

In addition, various attachment methods such as caulking, spot welding, and soldering are also planned for attaching the rod (3) a to the plate (3).

The embodiment shown in FIG. 11 shows the construction of a buckle for a band, a necklace, a bracelet, etc.
