Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an engagement tool used for imprinting a handbag using the magnetic force of a permanent magnet, and particularly to a mounting structure for a permanent magnet member.

Therefore, in the past, this type of retainer generally utilized a washer with leg pieces, but with this washer structure, it was difficult to increase the number of parts due to the increase in the number of parts. Installation requires a lot of manufacturing time, which relatively increases the product cost.

In addition, in the case of a washer whose main body is a bent leg piece, it is difficult to attach decorations such as decorative buttons to the mounting surface, and more labor and materials are required to attach the decorations. It is something.

Next, in the conventional structure of such leg pieces, a relatively large number of end faces are required to be bent and locked, and this is not necessarily good in terms of appearance, especially when attaching another piece of leather to the base. This exposes the drawbacks of not doing so.

The present invention was devised in particular in view of the inconveniences of the conventional engagement tools, and is a bottomed tubular mounting structure whose tip portion is expected to be collapsed in contrast to the conventional leg structure. In addition to reducing product costs by reducing the number of parts and installation effort, the installation has a relatively simple end face, significantly improving the external appearance, and allows one-touch installation of decorations, especially decorative buttons, etc. as needed. This was made possible by

Hereinafter, details of the present invention will be explained with reference to a typical embodiment shown in the drawings. (1) is a permanent magnet, and various magnets can be used without being limited to any particular material or shape. At the same time, the engaging hole (1)a is opened as a single component or multiple components from one pole end face to the other pole end face, and a ferromagnetic plate ( 2), and this plate (2) and magnet (1)
and a case (3) made of a non-magnetic material such as a brass plate.

A typical case is that the case (3) is fitted so as to cover the IL end surface of the plate (2) and the circumferential surface of the hole (1) a except for the opening. ) Bend its end face toward a, and similarly bend the engaging piece (3) a of the opening edge against the end face of the plate (2) that does not come into contact with the permanent magnet (1). This is what I did.

Regarding the structure of the visible magnet (1) and the ferromagnetic plate (2),
Separately prepare a mounting plate (4) whose approximately central portion is bulged out by drawing or the like to form a bottomed pipe portion (4)a, and bend the peripheral edge of this mounting plate (4) to form an edge. (4) As part b, bend the plate (2) to the joint surface of the permanent magnet (1) and attach the plate (
4) and the plate (2) are fixed together as one body, and this is integrated with the magnet (1) with a case (3).

Incidentally, in case (3) in the description above, the magnetic shield plate (5) is attached to the surface of the magnet (1) that is not attached to the plate (2).
In the case where the plate (5) is attached to the case, the plate (5) is constructed into a cylindrical shape as shown in Fig. 4, and the case (3) is attached as shown in Fig. 5. ), and the case where the magnet (1) and the plate (2) are directly bonded is planned.

Next, for installation, create an intervening gap at the bent edge (4)b of the plate (4), and bend it along the outer periphery of the plate (2) to ensure close contact between the magnet (1) and the plate (2). In the case where a circumferential concave stepped edge corresponding to the wall thickness of the edge (4) b is provided as shown in Figures 1 to 9, and in the case where the plate (2) of the magnet (1) is provided as shown in Figure 10. It is planned that a similar concave step edge will be provided along the outer periphery of the joint end surface.

In contrast to the plate (2) having such a structure, no protuberance is provided in FIG. 1, and the ferromagnetic rod (6) in the other ferromagnetic plate (5) is ) when the end surface of the magnet (1) is brought into direct contact with the surface of the original (2), and when the length reaches approximately the middle of the hole (1) a of the magnet (1) as shown in Figure 2. A case in which the rod (7) is set upright and brought into close contact with the rod (6) in the middle of the chain hole (1) a in Fig. 12, and a case in which the rod (7) is installed in the case (3). The contact position of the magnet (1) with the plate (5), including the rod (7) at the end of the hole (1) a.
It is envisaged that a plate (5) having a peripheral engagement flange (5)a will be placed in close contact with the plate (5).

Next, when attaching the rod (7), there are two cases: one in which the rod (7) is caulked as shown in Figs. Other attached structures are planned, including screwing as shown in the figure, sticking as shown in Fig. 8, or integrally fabricating as shown in Fig. 9.

When fixing a fastener based on a magnet (1) having such a structure to the base (8), the tube part (4) of the mounting plate (4) inserted through the base (8) is used. ) A case where a is directly crushed and engaged to the other end surface of the base (8), and a case where a washer (8) is interposed as shown in Fig. 14 in this crushing engagement. Then, insert the mounting member (lO) having the funnel-shaped mounting pipe portion (10) a into the large version (8) from the other end surface of the large version (8).
The pipe part (4) a of the previous mounting plate (4) is press-fitted into the pipe part (10) a by piercing the pipe part (10) a.
4) In the case where an 8-head configuration is brought about and the head ends of this configuration are closely engaged with the inner circumferential wall surface of the tube portion (10) a, other considerable methods are planned.

In addition, bend the periphery of this mounting member (10) and attach it to the decorative button (1
By attaching the periphery of 1) like a fullum,
Separate installation means for the decorative button (11) is not required, and this type of installation of the decorative button (11) can significantly reduce costs.

The present invention is a large version (8) due to its characteristic structure in the story.
It is extremely easy to install the engaging tool on one side, that is, on the plate (4
) is made possible by simply press-fitting or press-fitting and crushing the pipe portion (4)a, and the number of parts for installation is reduced as much as possible, and the appearance after installation is also extremely good.

In other words, as in the past, the method of mounting with a leg piece is by using a plate, and the method of mounting with a washer is used for mounting the leg piece through the plate, whereas the method of mounting with a magnet (1) is different from the method used previously. It is sufficient to simply crush the pipe portion (4) a of the plate (4) that has already been integrally attached to the engagement tool through the large plate (8).
10), this mounting member (10) is used.
), a simple press-fit into the pipe portion (10)a guarantees instantaneous and reliable fastening.

In particular, in such a simple press-fit fastening method, subsequent manipulation of the press-fit end, especially caulking, bending, etc., is not necessary, and the use of the decorative button (11) is completely possible. It is.

In addition, by changing the structure that was held at two or more fulcrums as in the conventional example to the tJi-fulcrums of the tube parts (4) a and (10) a, one-sided engagement with the magnet (1) is possible. A certain swing width is given to the tool, and this swing width makes it possible to maintain a more stable magnetic state with the ferromagnetic plate (5).
