Abstract

PURPOSE:To facilitate and ensure the mounting of an engaging means, by attaching a mounting wahser provided with bendable legs each outwardly projecting and having an acute pointed free end, onto the surface of each of ferromagnetic plates constituting male and female members, respectively, of the engaging means utilizing a permanent manget. CONSTITUTION:A ferromagnetic plate 2 is brought into contact with one pole- face of a permanent magnet 1 and is unitarily attached to each other by a non- magnetic case 3. A ferromagnetic rod 2a is projected from the plate 2 into a bore 1a in the magnet 1. On the other hand, a ferromagnetic plate 4 is magnetically detachably brough into contact with the other pole-face of the magnet 1 and the free end surface of the rod 2a In the engaging means constituted by such male and female members, a wahser 5a having bendable legs 5 is attahced to the surface of each of the plates 2 and 4, and the free end of each leg is formed into an acute pointed end 5b. Owing to the installation of the washers when the engaging means is attached to a handbag or the like by piercing a predetermined mounting reference surface with the pinted ends of the legs 5, the mounting is simple and reliable, and there is no possiblity of shaking of the engaging means after mounting.

Description

[Detailed Description of the Invention] The present invention discloses a retainer structure that uses permanent magnets to easily and reliably attach a leg piece for bending to a substrate surface for attaching a handbag, a shirt, etc. It is related.

Therefore, in the case of this type of retainer in the past, the ends of the bending leg pieces protruding from the male and female parts were made of rounded cedar wood, with one side of the rectangle being F. This has the trouble of requiring a cut in the board surface to which it is to be attached to be made in advance for the insertion of the leg piece.

Father, when making these cuts, how do you determine their position? It is important to be accurate, and there are no difficulties in the work.
It has the following.

The present invention was devised especially in view of the disadvantages of the bending leg piece III structure in the conventional IF tool, and
1.14) A bending leg piece with an acute-angled pointed end that protrudes outward from the surface of the free WA. The leg piece (51) is pierced by the pointed end, and the notch is opened and securely made so that the cut width of the % line notch is not too large or too short to prevent any wobbling after installation. .

In the present invention, the stopper is attached directly to the position, so that the position can be easily determined.

In the following, a typical embodiment of the one-thread engagement tool according to the present invention will be described with reference to the drawing number. It is a cylindrical permanent magnet with a ferromagnetic plate + 2 on the magnetic pole surface.
11? The wire plate 12) is attached to the magnet +1) with the case 13) made of a non-magnetic material, so that the case 131e part cannot be bent.

The ferromagnetic plate (4) and the ferromagnetic plate (2), which are in contact with the other magnetic pole surface of the magnet Ill in a detachable manner, are pushed by either or both of the ferromagnetic plates 121 and 141. The installed ferromagnetic rods 121a and 1141a are placed on the other plate (2),
14) Or, in a male tool, a female tool, and a twisting engagement tool, which are made to removably abut on the free end surface of the other rod (2) a, +418 through the hole ill a t-. Ferromagnetic plate 12), the bending leg piece t51 protruding outward on the (4) surface.
The leg piece (51) has an acute-angled pointed end (5)b.

Case 131) E, Wire plates 121, 141 and magnets are made of non-magnetic materials such as synthetic *n materials, aluminum materials, brass materials, etc. Thickness, color, and lighting options are appropriately selected and used.Thus, in the present invention, a bending leg piece (5) is provided.
The filter washer (5) a is made by bending four thin rectangular gold plates by equal dimensions from both ends to form a U-shape, and the free end is V-shape. Full of planned things.

The present invention effectively corrects the deficiencies of the prior art examples mentioned above by providing a unique structure for the construction.

To explain another typical example of W, in Fig. w In Case 3), the upper surface of magnet Il+ is liquid-separated and bent to the inner surface of hole 11)a. , the case 13) is tightly fitted.
Attach the washer (5) a to the other side and attach the leg piece 15.
)? It has a protruding t7S.

In Fig. 3, a washer (5) of the same diameter as the plate (2) is fixed integrally with the lower end of the AF case 131, and only the plate (4) is made of ferromagnetic material. Rod +41
a? It is caulked so that the free end surface of the pJ141a and the wire plate 12) can be magnetically attached and detached.
+4) I'm afraid of both (2) 8% +41! 1? It was established.

n 121 a% 14) The free end surface of a is brought into contact with the other.

In Fig. 5, a magnet Il+ is placed on the top surface of the stone (1).
The ferromagnetic plates (61) are stacked and covered with a shielding ferromagnetic plate (case 13) of the same shape as the case 13.

In Figure 6, %cough 1ilii141 is pressed against the curved surface, and this l contacts tJ! - The upper surface of the magnet Ill is made into a concave curved surface, covered with a case (3), and the inner surface of the hole 'II 8 is bent and cut out.

In Fig. 7, the upper peripheral edge of a shielding ferromagnetic plate (6) having the same size and shape as the inner upper surface of the magnet is shaved off on the upper surface of the magnet il) so that the upper edge flange of the case 13) is buried. It is designed to create the same surface as the top surface of #plate (6).

In the 51st!14th case, there is a convex strip 1 on the periphery of the case +3).
31 ai, and for some of the lines of magnetic force that leak, the protrusions 1318 ? Closed surface 131
The magnetic shielding effect is particularly complete by preventing direct contact with the material.

The interposition of the convex strip 13)a is such that a sufficient magnetic gap is provided between the surface of the plate (6) and the magnetic recording card or magnetic chip, etc. that is actually expected to come into contact with it. %
This prevents destruction of the magnetic recording area 0 due to some leakage magnetism from the 6i surface of the plate.

In the GTO diagram, the magnet 11) is simply attached to the ferromagnetic plate 12).

Therefore, the following specific effects are expected from the present invention.

That is, 1 ferromagnetic plate 12), a bending leg piece (51t-type washer with tA screwdriver (51a) with an acute-angled pointed end protruding outward on the 143 plane), which can be used for handbags, dress shirts, etc. Pierce the base surface with the pointed end.
It is easy to install, guarantees reliable installation, and only needs to be pierced through the tip of the tip, so it is possible to correct holes that are too small in width and make appropriate cuts.A, -! : This is a device that is designed to prevent vibrations from occurring on the mounting board of the engagement tool.

- As per A on the diagonal top The object of the present invention is to provide a T-type engagement tool which is extremely effective and can be installed without cutting.
