Abstract

PURPOSE:To promise reliable engagement which can be adapted in wide application field by employing a device A having the expanded head part at the upper end of ferromagnetic bar and and a device B of ferromagnetic plate having a hole which engages with such expanded head part and can be freely and removably attracted by a permanent magnet. CONSTITUTION:A case 5 and a magnet 1 are placed on a ferromagnetic plate 2 having a hole 2a bored at the center thereof in such a manner that the one magnetic pole surface of the magnet 1 is closely placed in contact with the plate 2 and a nail segment 5b provided at the aperture edge of case 5 is bent, thereby the internal magnet 1 and the plate 2 are integrally configurated. A ferromagnetic bar 3 is erected in the hole 2a of the ferromagnetic plate 2 through the holes 1a, 5a at the magnet 1 and case 5 integrally configurated and a washer 7 having a leg segment 6 is caulked with a protrusion 3b having the reduced diameter part of the bar 3 provided through the hole 2a. The ferromagnetic bar 3 has the expanded head part 3a in the opposite side of the protrusion 3b having the reduced diameter part. The device B is engaged with a device A having such structure. Namely, the device B has the hole 4a with which the expanded head part 3a of bar 3 is engaged and formed in such a thickness as ensuring sliding engagement.

Description

[Detailed Description of the Invention] This invention relates to a retainer using a permanent magnet.
This is related to the first generation of the engagement tool, which has achieved even stronger retention and widespread use due to the absorbing power of E + itself and the Katsurato city by Atsushi Yade.

So, has this type of engagement tool that lasts for 1 hour been devised in the past, using the sucking force of a permanent magnet or using the hook +'r-f of a protruding F mound? For retainers that use permanent magnets, there are two separate parts! '' to drive out the deviation in the direction perpendicular to the direction of the grinding stone. On the other hand, it is effective only when hanging in the same direction at a right angle to C, and the range of use is limited even on the lifting platform in the direction of A.

Therefore, the present invention is intended to be used as a belt buckle for pants, handbags, shoulder pegs, etc., or as a strap for handbags, bags, wallets, and other bags, or as a strap for books, or for cabinet boxes, etc. This book promises a wide range of uses, including as a closing tool for boxes in furniture, and as a tool for hanging various hangers.

Therefore, in order to obtain appropriate and large-scale effects on the basic characteristics, the present invention is designed so that fL(1)a is changed from one magnetic pole surface to the other magnetic pole surface. A ferromagnetic plate (2) is provided on one of the magnetic pole faces of the permanent can stone (1), and a ferromagnetic plate (3) is provided in 'F[1]a on the mounting plate (2).
) is erected and protrudes upward from the nucleation (1) a. One stop A with the upper diseased part of presentation (3) as the large head of 1 cedar (3) a; Opening the spout hole (4)a of the head (3)a1. In addition, the magnet (1) is placed at a point where the other IE device B is formed of a ferromagnetic plate (4) that is removably attracted to the other magnetic pole surface of the magnet (1), and such a purchase 5z
It is planned that considerable design changes will be made along with the main points of the project.

The details of the present invention will be described with reference to an exemplary embodiment shown in the drawings.This is an 1aid Mizuhisa stone and is intended to be used as a sintered stone, usually made of ferrite or the like.

Father, these magnets (1) and (2) have ft(1)a opened from one side of the magnetic pole face to the other side, and the capstone (
1) with a case (5) fitted over it.

In particular, a typical example of the nose (2) is an inverted plate-shaped, so-called Izr-
The magnet is made into a closed cylindrical shape, and the magnet (
Same diameter as hole (1) a in V\ in 1): D
It is designed to be used as needed.

The shape of this magnet (1) is cylindrical, prismatic, prismatic,
A cylindrical shape is planned, and cases (5
) is planned. (No. 2.31 Oka) Connect the case (5) and magnet (1) with a hole (2) in the center.
Place the stone (1) on a ferromagnetic plate (2) with a open side so that one magnetic pole surface of the stone (1) is in close contact with the mounting plate (2),
nl [Claw piece (5) provided in case (5) 〇 b
l-Magnet (]) and plate ° that are folded inside
(2) is constructed in one piece.

Next, the magnet (1) configured in the above-mentioned pole and line, and the case (5)
) in hole (1) a −, 15) a ? 4. Then, in the above procedure (3), the ferromagnetic plate (2) has a V-hole (2j a) with the forced out sex (3), and the nucleus (2) a K i is inserted. Hold the diameter-reducing protrusion (3) b and attach the leg piece (6).
A washer (7) having a shape is crimped.

The ferromagnetic formation (3) contains an enlarged head (3) a on the opposite side 1i1 of the diameter-reducing projection (3) b, and from the lower edge of the enlarged head (3) ) The height shall be such that a slightly circular gap is maintained in the upper 1tl11 part.

The portion having the above-mentioned release is designated as a stopper A, and the portion that engages with the stopper A is designated as +h@B.

That is, the stopper B is a strong magnetic plate (4) whose shape is variously planned, but the stopper A VcIP'-Keruyo (3)
)'s large head (:l a is inserted into the hole (4-a'y
It has the above-mentioned strength! Enlarged head (3) a lower loose part and case (5) upper 1Il1 of a bullet (3)
The thickness is such that a number of slides can be inserted into the circular gap between the parts.

Fig. 4 shows a cross-sectional view of the typical example of the present invention, in which Fi5L is used in the process of manufacturing, but it is also planned to change the shape of the Tsukada-related keichin as shown in Fig. 5. , in the case of such a shape, very quick removal is guaranteed.

Furthermore, the same effect as described above can be achieved by covering one large head (3) a of the ferromagnetic cage (3) with rubber or a similar synthetic resin.

The present invention can effectively correct the deficiencies of the prior art described above by combining a permanent magnet with a strong magnetic force, that is, an engaging protrusion. The following specific effects were expected.

That is, in the example of Ni + R11, which can be written, the r of the engagement tool
The scope of replacement was limited, and it was necessary to create engaging tools that corresponded to these differences, which inevitably led to relatively high production costs.

In view of this, we have devised an engaging tool that can be used for a wide range of purposes, thereby providing an inexpensive retaining tool.
This is what I saw.

In addition, a hole 25 is opened in the upper permanent magnet next to the magnet, and a ferromagnetic four, -[", or engaging protrusion 25 is erected in the upper permanent magnet. It is possible to promise a strong and solid engagement without simply relying on the combination of Yuseki's suction power and the engagement protrusion.

Historically, when the buckle of an old band is used to protect the engagement device, it is particularly effective, and the band can be easily removed by the tension of the H tabend. When Jy is engaged in a fixed position and once engaged, VL- is a reinforced bullet, that is, the large head of the retaining protruding gravel prevents the stop B from detaching due to pressure from the body. It gives you 1 defense.

As stated above, the object of the present invention is to provide an inexpensive engagement tool that is applicable to a wide range of areas and that promises a large and reliable engagement.
