Description

[Detailed Description of the Invention] The present invention relates to the disclosure of a structure for simple mounting that allows fast and reliable mounting of an object to be mounted, such as an engaging tool, on a substrate surface. .

In the past, there have been various methods for attaching this type of engagement tool, and many attempts have been made to improve it.

However, each of them had advantages and disadvantages, and they were not necessarily satisfactory.

Particularly, the reduction in the number of parts, the reduction in the number of parts required for installation, the reduction in work effort, the accuracy of installation, and the strength of installation often tend to contradict each other.

In the present invention, such conventional mounting is intended to reconcile the contradictory disadvantages of the means, reduce the number of parts, and effectively reduce the labor involved in mounting.

Therefore, in the present invention, the female fitting is attached by providing a bottomed hole portion with a cylindrical bulging hole having a guide piece protruding outward, and the male fitting is attached by using a simple bottomed tube. The body is designed to bring out the high contact friction due to the pressure-tight fit unique to the cylindrical body and the excellent strength characteristics unique to the cylindrical body, and the number of parts is kept to the minimum necessary, and the installation is a simple fit. It is assumed that crimping is sufficient, and that it is possible to achieve various effects that are not found in conventional attachment methods, and the gist of the invention is set in the claims, and the gist of the structure is embodied. The following is a typical example, and considerable design changes are planned for this example.

The mounting according to the present invention will be described below with reference to a typical embodiment whose structural details are shown in the drawings. Reference numeral 1 indicates a female fitting main body which is integrally constructed, and a bottomed hole 1b in a cylindrical portion 1a. The bottom of the hole 1b is made up of a metal core 10, and the bulging holes 1f to 1f extending outward from the hole 1b are formed in the lower part of the cylindrical portion 1a. For the purpose of smoothing the crushing and swelling of the hole 1f and improving the swelling and biting into the hole 1f, the guide pieces 1g to 1g are attached to the hole 1f.
It is designed to integrally protrude outward from the edge of the hole.

In addition, the guide piece 1g shall be integrally provided on either the upper or lower edge of the hole 1f, and if it is provided on the lower edge, it will be placed on the upper outer side, and if it is provided on the upper edge, it will be placed on the lower side. These are arranged so as to protrude outward from the sides.

Furthermore, an interposed part of the washer 2 is provided between the core metal 1c and the cylindrical part 1a, and the bulging end surface of the core metal 10 is connected to the engaging end surface 1d of the washer 2.
In addition, the outer diameter of the interposed part of the washer 2 is slightly enlarged compared to the outer diameter of the cylindrical part 1a, and a caulking edge 1e is provided.
The end face 1d and the caulking edge 1e are pressed and fastened together.

For such attachment, the male fitting 3 has a bottomed cylindrical portion 3a having an outer diameter that is press-fitted into the female fitting hole 1b, and
It is constructed with an edge flange 3b extending laterally to the opening edge, and is inserted through one end surface of the hole 4a made in the substrate 4 with the washer 2 as the engagement end surface, as in the embodiment shown in FIG. Installation is done by fitting the cylindrical part 3a into the female fitting main body 1, and press-fitting the cylindrical part 3a into the bottom of the hole 1b with its entry blocked, so that the thickness of the cylindrical part 3a is more than the hole 1b It is guided to the bulging hole 1f using the guide piece 1g as a guide,
This constituent material is led out further to the outside of the cylindrical portion 1a through the hole 1f without being obstructed by the substrate 4 by the guide piece 1g, and the male and female attachments ensure complete integral attachment of the male and female tools.

That is, the male and female attachment according to the present invention is performed on the female tool main body 1 in the tool.
This ensures installation using only washers 2 and male fittings 3, and the number of parts is kept to a minimum.Furthermore, the dimensional accuracy of the installation is improved by changing the fitting pressure, and in particular, correction of parts accuracy is This was made possible by adjusting the fitting pressure.

In addition, it has been proven that the strength of pipes is generally superior to that of solid pipes;
Such strength characteristics are further enhanced by superimposing the two.

Furthermore, the structure of the cylindrical portion 3a ensures more reliable adhesion to the inner wall surface of the hole 1b due to the elasticity of the cylindrical portion 1a and the elasticity of the cylindrical portion 3a.

In particular, the frictional resistance having such elastic force is generated between the cylindrical portion 3a and the hole 1.
b It can be seen over the entire surface, and due to the enlargement and biting of the inside of the cylindrical part 3a from the hole 1f, the integrity of the fittings is usually considered to be greater than that of the fittings, and once it has been attached, it cannot be removed. It was considered completely impossible.

Incidentally, for installation, it is also possible to omit the edge flange 3b of the male tool 3, interpose a washer 5 separately, and swage the opening edge 3c of the male tool 3 onto the surface of the board 4. , there is no discernable difference in the effects produced.

In addition, it is planned that the mounting will utilize the edge flange 3b of the male tool 3 or the washer 5 to interpose a button or other decoration between the board 4 and these components. be.

It is also separately planned to utilize the holes in the cylindrical portion 3a of the male tool 3 itself for the attachment of the five other parts.

In contrast to the basic configuration example shown in FIGS. 3 and 4, as well as FIGS. 7 and 8, the cylindrical portion 1a and the core bar 10 in the previous embodiment are In particular, a cylinder body 11 with a bottom and a bulging hole 11a having a guide piece 11b at the opening edge on the circumferential surface of the bottom and a core bar 12 having a narrow diameter frame part 12a are prepared. However, the small diameter frame portion 12a of the core bar 12 is caulked to the inner bottom surface of the cylindrical body 11 with a washer 13 interposed therebetween, thereby forming a female fitting.

The thus constituted attachment is the male fitting 14 for attachment to the female fitting.
As in the paper, a cylindrical part 14a with a bottom and an edge flange part 14b extending laterally from the opening edge of the cylindrical part 14a,
The cylindrical portion 14a of the male tool 14 is press-fitted into the cylindrical body 11 of the female tool through the substrate 15.
After contacting the bottom surface of the cylinder 11, it is gradually crushed and the cylinder 1
In particular, the guide piece 11b in the hole 11a is used as a guide to lead out outward from the hole 11a, and the two are completely fixed together.

In addition, in this installation, the male tool 14 is attached to the edge flange 1 in the same way as before.
4b is omitted and a washer 16 is inserted instead to form the opening edge 14c.
A method of caulking the washer onto the 16 sides was also planned.

Examples of such embodiments, particularly applications of the first embodiment shown in FIGS. 1 and 2 and FIGS. 5 and 6, are further shown in FIGS. In the so-called male engagement tool a, the core bars 10 and 12 attached in the embodiment are used as engagement rods that also serve as magnetic paths, and the washers 2 and 13 are magnetic plates that also serve as magnetic paths on the magnetic pole surfaces. This is disclosed as a corresponding female engagement tool.

Therefore, this retaining female member has a permanent magnet 20 with a retaining hole 20a opened from one of the magnetic pole faces to the other magnetic pole face.
, a washer 21 made of a ferromagnetic material attached to the bottom magnetic pole surface of the magnet 20, and a case 22 made of a non-magnetic material.
together with the core metal 1 of the male engaging tool a.
A core bar 23 serving as a magnetic path corresponding to 0.12 is erected on the surface of the washer 21 so as not to contact the inner wall of the magnet hole 20a, and the lower narrow diameter frame portion 23a of the core bar 23 is mounted on the substrate. 24. Attachment is carried out by inserting the washer 21 and fitting it from the other side of the board 24 using a male fitting 25.

In the embodiment shown in FIG. 10, the core bar 23 has a length that reaches the opening edge of the magnet hole 1a, and in the embodiment shown in FIGS. 11 and 13, a magnetic shield is used. A ferromagnetic plate 26 is fixed onto the free magnetic pole surface of the magnet 20.

In FIG. 12, this coated ferromagnetic plate 26 is used as a partial substitute for the case 22, and in the embodiment shown in FIG. A magnetic gap 27 is provided between the case 22 and the magnet 20.

The embodiment shown in FIG. 14 is another embodiment of the edge flange 22a of the female retaining tool shown in FIG. 13.

Next, in the embodiment shown in FIG. 15, the magnetic end surface is made into a rounded surface or a tapered surface that slopes toward the hole 20a, which makes the engagement of the core metal smoother and improves the plating on the magnetic surface. That is.

Furthermore, in the embodiment shown in FIG. 16, the washer 21 is laterally extended to serve as an attachment end surface 21a for a band or the like, and is used as an engagement means for a shoe band, necklace, or the like.

Next, the embodiment shown in FIG. 17 has an edge flange 22a in the female engaging member.

As a result, when the case 22 is rotary plated, the engaging edge flange creates a gap between it and the other case 22 to avoid close contact, and cases having different diameters of different sizes can be mixed and rotary plated. In this case, since they do not fit into each other, peeling does not occur on the plated surface.

Incidentally, although the installation at an angle is related to a retaining device that uses a permanent magnet, it is of course possible to install other general buttons and other decorative devices, and none of them are possible. Even in this case, the desired fixing effect can be achieved.
