Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the disclosure of a simple mounting structure for a stopper, particularly an engaging member, using a permanent magnet.

Therefore, in order to fasten an engaging tool using this type of permanent magnet, especially as a means for engaging a substrate such as a handbag, it is customary to separately prepare a washer or the like having a leg piece, and attach it to a magnet. Assemble the permanent magnet together with the magnetic plate, and place a mounting washer or the like having another engagement hole on the other end of the board, insert the leg piece of the washer through this, and then bend and lock it. However, a pair of parts is required in addition to the ferromagnetic plate, and the structure of the parts used is complex, requiring a lot of time and effort for press processing, etc., and it is difficult to assemble. This requires a lot of work and labor, and as a result, the manufacturing cost is relatively high.

In addition, in the case of fastening by inserting and bending the washer leg pieces, the engaging tool itself tends to come off easily when external force is applied, especially when a tensile force is applied, so it is not always possible to securely and securely stop the engaging tool. It could not be used as a means of wearing clothes.

The present invention was devised in particular in view of the inconveniences of the conventional locking structure of the engaging tool using permanent magnets, and the number of assembled parts is kept to the minimum necessary. The construction of these assembled parts is simple, and the assembly and installation effort is low, so the manufacturing cost is low and reliable fastening is guaranteed. As long as there is no tearing or damage to the mounting plate, there is no danger of it coming off. Furthermore, this mounting plate can be used to easily attach decorative buttons, etc., making it possible to provide this type of special decorative fastening at a low cost.

Therefore, in order to achieve appropriate and purposeful effects on these characteristics, the present invention is structured so that one of the permanent magnets 1 has a hole 1a directed from one magnetic pole surface a toward the other magnetic pole surface b. A ferromagnetic plate 3 is provided on the magnetic pole surface a, and a ferromagnetic plate 2 is attached to the other magnetic pole surface b in a freely adsorbable and removable manner, and the ferromagnetic rod 2a protruding from the ferromagnetic plate 2 is placed in the hole 1a. In the engagement tool which is adapted to adsorb and detachably abut on three surfaces of the ferromagnetic plate,
A concave portion 1b is provided on the surface of the permanent magnet 1 to which the ferromagnetic plate 3 is attached, and a mounting rod 4 inserted from the other side of the mounting board 6 of a handbag or the like to which the engagement tool is attached is inserted into the recessed part 1b. The free end of the mounting rod 4 is inserted into the ferromagnetic plate 3 so as to protrude into the recessed part 1b of the permanent magnet 1, and the point is locked therein, and further a considerable design change is made in accordance with the gist of the invention. is planned.

The details of the engaging tool according to the present invention will be explained below with reference to a typical embodiment shown in the drawings. It is a permanent magnet designed to be assembled and produced, and a ferromagnetic plate 3 is fixed to the magnetic pole surface a of this magnet 1, and an engaging male plate 3 is attached to the other magnetic pole surface b so as to be able to be attracted and detached. A ferromagnetic plate 2 serving as a tool is attached, and a ferromagnetic rod 2a protruding from the ferromagnetic plate 2 is inserted into the hole 1a of the permanent magnet 1.
It is made to come into contact with the three surfaces of the ferromagnetic plate via the ferromagnetic plate so as to be able to be freely attracted to it.

Next, as a means of fixing the ferromagnetic plate 3 to the permanent magnet 1, fixing is planned using a cover made of a non-magnetic material that serves as a protective coating for the permanent magnet 1.
The cover 5 is usually made of brass and is shaped like a dish cylinder with an open end, and locking pieces 5a to 5a are provided protruding from the edge of the opening, and the plate 3 is held down by holding the locking pieces 5a. At the same time, a part of the upper surface is opened to communicate with the hole 1a in the permanent magnet 1, and the opening edge is bent in the direction of the hole 1a to form an engaging edge flange 5b.
That is.

As a means for fixing the female fastener having such a configuration to the mounting board 6 of a handbag, etc., the board 6 is used.
A mounting plate 7 is attached and arranged on the other side of the mounting plate 7.
It is also connected to the ferromagnetic plate 3 at the end of the female stopper using a mounting rod 4.

That is, the permanent magnet 1 to which the ferromagnetic plate 3 is fixed
Two or more recessed portions 1b are provided on the magnetic pole surface a side, and a hole 3a having a diameter slightly smaller than the diameter of the mounting rod 4 is provided on the ferromagnetic plate 3 surface corresponding to the recessed portion 1b. .

In addition, the mounting plate 7 has a hole 7a for inserting the mounting rod 4 at a position corresponding to the hole 3a of the ferromagnetic plate 3, and the engagement tool is inserted into the mounting board 6 of a handbag or the like. The ferromagnetic plate 3 and the mounting plate 7 are opposed to each other from both sides of the base plate 6, and the mounting rod 4 is inserted into the holes 7a and 3a from the mounting plate 7 side and fixed thereto.

The holes 3a of the ferromagnetic plate 3 are provided with radial cuts on the periphery so that the mounting rod 4 can be inserted through the holes 3a and the plate 3 can be easily inserted.
It was also taken into consideration to improve the bite and adhesion.

The present invention has the above-mentioned characteristic configuration, in particular, a simple method in which the plates 3 and 7 are attached via the substrate 6, and the opposed plates 3 and 7 are attached to the rod 4 through piercing. By making it possible to securely fasten the decorative button, we have achieved the above-mentioned characteristics, especially reducing production costs, reducing assembly effort, and ensuring secure fastening. It has the following features:

In addition, since the mounting rod has a small diameter, the hole made on the mounting board surface to insert the mounting rod can be of a small round diameter, and there is no need to create a gap in the leg part like a slit for inserting a conventional mounting leg piece. do not have.

In addition, with conventional products, if the mounting slit is cut incorrectly, the cut is large, resulting in a defective product, but with the present invention, there is no problem even if the mounting position is incorrect. .
