Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a magnetic badge that can be attached to clothing or the like and a method for attaching a magnet to a synthetic resin member.

[0002]

2. Description of the Related Art Conventionally, a needle-shaped pin provided on the back surface of a decorative body is pierced into a cloth such as clothing, and the tip of the pin protruding on the back surface of the cloth is locked by a fastener to coat the decorative body. Badges to be attached to are known. The conventional badge is
The portion to be a decorative body is formed as a metal plate-like body, the outer shape of which has a shape that represents a predetermined motif, those patterns and the like are drawn on the front surface, and the needle-shaped pins on the back surface. Was attached by welding.

[0003]

SUMMARY OF THE INVENTION The above-mentioned conventional badge is
Its manufacturing cost is low. However, since the needle-shaped pins are provided on the back surface of the ornament, the ornament has a shape like a thumbtack. Such a structure is considered to be relatively unlikely to be accidentally injured by a pin for children of an age that can be used with caution, but as a badge for infants and younger children, it is considered to be a preferable structure. I can't say.

The present invention has been invented in view of the above points, and in order to provide a badge that infants and lower grade children can use with peace of mind, a relatively soft synthetic resin is used and a needle pin is used. A first object is to provide a structure of a badge including a decorative body that does not have the badge.

Further, in order to solve the first problem, the present invention provides a structure of a badge which can be attached to clothes or the like by using a magnet having a strong magnetic force. However, if a magnet with a strong magnetic force such as a neodymium magnet is used, the magnetic force will be superior to the adhesive force by simply forming a hole in a soft synthetic resin that will be the decoration and inserting the magnet with an adhesive, It turns out that the magnet comes out from the hole. This is because the neodymium magnet itself does not easily adhere to the adhesive, and because the synthetic resin such as PVC is soft, the badge body flexes as the badge is used repeatedly, and the adhesive separates from the magnet, causing the magnet to separate. It is thought that this is due to the property that it becomes easy to come off. Therefore, according to the present invention, a resin portion (resin layer) is integrally provided by molding at the portion where the magnet is joined to the decorative body, and the resin portion is adhered to the badge body, so that the magnet is less likely to come off from the badge body. It is a second object to provide a structure for attaching a magnet to a badge and a synthetic resin member.

BEST MODE FOR CARRYING OUT THE INVENTION [First Embodiment] An embodiment of the badge of the present invention will be described in detail below with reference to the drawings. FIG. 1 is an exploded configuration diagram of the badge 1, in which reference numeral 3 indicates a badge body, and 5 indicates an attachment member for attaching the badge body 3 to clothing or the like. The badge body 3 is composed of a decorative member 7 and a magnet 9 attached to the back surface of the decorative member 7. Further, the decorative member 7 is attached to the clothing or the like by magnetically attaching the attachment member 5 to the magnet 9 attached to the back surface of the decorative member 7 with the cloth or the like of the clothing sandwiched therebetween.

The decorative member 7 is made of PVC resin (polyvinyl chloride resin) as an optimum embodiment according to the present invention. The PVC resin is a relatively soft synthetic resin at room temperature, and the decorative member 7 is made of the PVC.
A resin is used to form a motif such as an animal, a plant, or an animated character in a three-dimensional shape. Further, the decoration member 7 is mainly formed in the three-dimensional shape imitating a motif, and the back surface (the surface on which the magnet 9 is provided) 7a is formed relatively flat. On the back surface 7a of the decorative member 7, a fitting hole (mounting portion) 11 is provided as a mounting portion to which the magnet 9 is mounted. The fitting hole 11 is, for example, a bottomed recess having a diameter of about 8.1 mm and a depth of about 3.1 mm, and is formed at the time of molding the decorative body 7. The size and shape of the fitting hole 11 is such that the magnet 9 including the resin portion provided on the surface of the magnet 9 described later is inserted and
It is formed in such a size and shape that an appropriate adhesive layer can be formed between the resin portion and the resin portion.

As the magnet 9, a neodymium magnet which is a rare earth magnet having a strong magnetic coercive force is used. The magnet 9 is formed in a cylindrical shape having a diameter of about 6 mm and a height of about 5 mm, and a resin portion 13 is integrally provided at least in a portion inserted into the fitting hole 11 of the decorative member 7. The resin portion 13 is the magnet 9
It is formed by molding on the surface of. That is, the resin member 13 is integrally provided on the surface of the magnet 9 by injecting a molten resin around the magnet 9 using a predetermined molding die and solidifying the resin. Further, ABS resin, which is harder than the PVC resin, is used as the most suitable resin material for the present invention. In this way, the resin portion 13 having an outer diameter of about 8 mm and a height of about 3 mm is formed on the one end surface of the magnet 9.

As described above, the resin portion 13 is formed on the surface of the magnet 9.
The reason why the resin is provided to the magnet 9
The reason why it is provided on the surface will be described. That is, PV
When a hole is formed in a decorative member made of C resin and a magnet is directly bonded to the hole with an adhesive, the attached magnet is likely to come off the decorative member. This is considered to be due to the low adhesive strength between the adhesive used and the magnet due to the nature of the material. In addition,
In this case, it is conceivable that the surface of the magnet is subjected to a surface treatment by plating or other means to increase the adhesive strength with the adhesive, but this is not adopted in the present embodiment because the manufacturing cost becomes high. Further, as a reason why the magnet is likely to come off, it can be said that the PVC resin is a flexible material at room temperature, whereas the magnet is a metal and thus is not flexible. That is, since the member that deforms with respect to the magnet that does not deform is bonded via the adhesive, the adhesive layer also deforms slightly with the deformation of the resin, and the magnet and the adhesive gradually separate due to the repetition, It is thought that the magnet will come off. Another big factor is that the magnetic force of the magnet is very strong. That is, the neodymium magnet used in the present invention has a magnetic force of several times to 10 times that of the conventionally generally used ferrite magnet. Therefore,
It is possible to provide a badge that does not easily come off even when it is attached to clothes or the like, but the fact that it has a magnet that is superior in adhesive strength to the adhesive that bonds the decorative body to the magnet is also a major factor. For the above reasons, it was devised and adopted to use the fixing method via the resin portion 13 instead of directly connecting the decorative member 7 and the magnet 9.

Regarding the method of connecting the magnet 9 and the resin portion 13, if the magnet 9 and the resin portion 13 are connected by using an adhesive, the resin 9 is removed from the resin portion 13 for the same reason as above. It becomes easy to come off. Further, for the following reason, it is decided to adopt a joining method by molding a magnet and a resin portion without using an adhesive. That is, most of the surface of the magnet is not a mirror-like surface but a rough surface unless it is subjected to a surface treatment or the like. Therefore, if a molding method is adopted in which all or part of the magnet is inserted and the surface is covered with resin, the resin is solidified according to the fine irregularities on the magnet surface that is a rough surface, It is considered that the magnet and the resin portion are bonded more firmly than when an adhesive is used. For the above reason, the joining method shown in this embodiment is adopted.

Next, the attachment of the magnet 9 to the decorative member 7 will be described. FIG. 2 shows a sectional view when the magnet 9 is attached to the decorative member 7. That is, the magnet 9 provided with the resin portion 13 on the surface is inserted into the fitting hole 11 of the decorative member 7 and fixed by the adhesive. At this time, the fitting hole 11 is in a state of being bonded to the resin portion 13,
In this embodiment, the PVC resin and the ABS resin are bonded to each other, and they can be firmly bonded to each other with an adhesive. Further, as described above, the resin portion 13 and the magnet 9 are joined by molding, and since they are firmly joined to each other, the magnet 9 is firmly joined to the decorative member 7 (fitting hole 11). It is possible.

Next, the structure of the mounting member 5 will be described. The mounting member 5 includes a metal piece (ferromagnetic material) 15 for magnetizing the magnet 9 through clothing and the like, and a first frame for sandwiching and holding a part of the metal piece 15 from both sides. It is composed of a member (male frame) 17 and a second frame member (female frame) 19. In this embodiment, the metal piece 15 has a diameter of about 12 m.
It is a metal disk made of a ferromagnetic material having a thickness of m and a thickness of about 1 mm. For example, an iron plate is used to magnetically attach the magnet 11.
In addition, the said iron plate employ | adopts what performed the chrome plating process from a viewpoint of a damage prevention and a rust prevention by a direct contact with the magnet 9.

The first frame member 17 and the second frame member 19 which expose and sandwich a part of the metal piece 15 are both made of ABS resin. The first frame member 17 has a diameter of about 30.
mm, the thickness is about 1.5 mm.
Diameter of about 8 mm for exposing the metal piece 15 at approximately the center
Is a member provided with a circular hole 17a. The back surface (joint surface with the second frame member 19) 17b of the first frame member 17
Is provided with a circular recess 17c having a diameter of about 13 mm around the circular hole 17a. In addition, the back surface 17b of the first frame member 17 has 3
Protrusions 17d are provided at the places.

The second frame member 19 is the first frame member 1
It is formed in a substantially similar form to 7. That is, it has a disk shape with a diameter of about 30 mm and a thickness of about 1.5 mm, and has a diameter of about 8 for exposing the metal piece 15 at the approximate center.
This is a member provided with a circular hole 19a of mm. On the back surface (joint surface with the first frame member 17) 19b of the frame member 19, a circular recess 19c having a diameter of about 13 mm is provided coaxially with the circular hole 19a, and holes 19d are provided at three locations on the periphery. . Then, the first frame member 17 and the second frame member 19 are combined, and the metal piece 15 is held in the space formed by the circular recesses 17c, 19c of each member. The second frame member 19 has a structure in which it is adhered to each other with an adhesive. At this time, the first frame member 1
7, and the projections 17d and the holes 19d provided on the respective back surfaces 17b and 19b of the second frame member 19 are fitted to face each other,
Positioning is performed so that the first frame member 17 and the second frame member 19 are coaxially coupled.

Mounting member 5 formed by the above construction
Has a disk-shaped appearance, has a recessed portion (recessed portion formed by the circular holes 17a and 19a) in substantially the center of both surfaces, and has a shape in which the metal piece 15 is exposed as the bottom of the recessed portion. There is. Then, the metal-attached portion 1 when the metal piece 15 exposed at the bottom of the hollow portion is magnetically attached to the magnet 9 through the clothing 9 or the like.
5b (see FIG. 3). Further, the periphery of the recessed portion is a contact surface 5a, which is a portion that comes into contact with the cloth material of the clothing when the decorative member 7 is attached to the clothing or the like. Since both sides of the mounting member 5 are configured substantially the same, any surface on the first frame member 17 side or the second frame member 19 side can be magnetically attached to the decorative member 7. .

Next, how the badge 1 having the above structure is attached to clothing or the like will be described with reference to FIGS. FIG. 4 shows a badge 1 according to the present invention and a cloth material 2 such as clothes.
1 is a cross-sectional view showing a state in which the badge 1 is attached.
It is sectional drawing which showed the state which attached to the cloth material 21, such as clothing. As shown in FIG. 4, when the position for attaching the badge 1 is determined, one of the contact surfaces 5a of the attachment member 5 is brought into contact with the back surface 21b of the cloth material 21. Next, the cloth 9 is arranged so that the magnet 9 provided on the badge body 3 is in contact with the surface 21a of the cloth material 21 on which the attachment member 5 is arranged. Then, the magnet 9 of the badge body 3 is magnetically attached to the magnetically attached portion 5b of the mounting member 5. That is, as shown in FIG. 5, when it is attached to the cloth material 21, the magnet 9 projects from the back surface 7a of the badge body 3 (decorative member 7), and the magnetized portion 5b of the mounting member 5 is recessed. Therefore, the convex portion of the magnet 9 and the magnetized portion 5b
The cloth material 21 is sandwiched between the concave portions. As a result, the badge 1 does not simply sandwich the cloth material 21 but
Since the cloth 21 is sandwiched in a deformed state, the attached badge 1 is prevented from shifting with respect to the cloth 21.

[Second Embodiment] In the first embodiment, as a method of attaching the resin portion 13 to the magnet 9, the resin portion 13 is fixed to one end of the magnet 9 formed in a cylindrical shape by molding. I explained. Next, as a method of attaching the resin portion to the magnet, the structure of the badge body 23 adopting another embodiment will be described. FIG. 6 is a cross-sectional view of the badge body 23 according to the second embodiment.
Is a decorative member, 27 is a magnet, and 29 is a resin part. Magnet 2
For 7, a neodymium magnet is used as in the first embodiment. Further, the magnet 27 has a columnar shape, and a groove 27a having a predetermined depth is provided on the outer circumference on one end side thereof, and a resin portion 29 is provided so as to cover the groove 27a.

That is, the resin portion 2 provided on the magnet 27
9 is made of ABS resin or the like as in the first embodiment, and the mounting method is also the same in that it is integrally molded on one end side of the magnet 27. The difference from the first embodiment is that a groove 27a having a predetermined depth is formed on the outer periphery of the magnet 27, and a resin portion 29 is provided so as to cover the groove 27a. By providing the groove 27a in this manner, the molten resin flows into the groove 27a during molding, and in that state, the magnet 2
A resin portion 29 is molded on 7. Therefore, it is possible to provide a structure in which the coupling force with the magnet 27 is higher than that of simply providing the resin portion on the surface of the magnet, and the resin portion 29 does not come off unless the resin portion 29 is broken. As described above, in the second embodiment, the magnet 27 formed in this way has the same decoration member 25 as in the first embodiment.
It is characterized in that it is adhered to the fitting hole 31 of No. 1 by an adhesive. In this embodiment, the groove 2 is formed on the outer circumference of the magnet 27.
Although 7a is formed, the same operation can be achieved by partially forming a recess instead of the groove 27a or adopting a shape such that the outer shape is deformed.

Although the first and second embodiments have been described as the most suitable examples according to the present invention, the following structures are adopted without being limited to the modes used in the above-mentioned embodiments. It is also possible to do so. Further, in the above-described embodiment, the badge main body is provided with the magnet and the mounting member is provided with the metal piece, but the badge main body may be provided with a metal member such as iron, and the mounting member may be provided with the magnet to be magnetically attached. . Further, in the above-described embodiment, the mounting member is formed in the shape of a disc, but it may be a square or a polygon, and the shape is not particularly limited as long as the badge body is magnetically attached. Further, in the above embodiment, the decorative member is described as a three-dimensional object such as an animal, a plant, or an animated character, but the application to a name tag, school badge, company badge, etc. attached to clothes is particularly Not limited. In the above embodiment, the badge 1 is attached to the cloth material 21 for description, but the member to be attached may be made of vinyl or paper in addition to the cloth material.

The range covered by is not particularly limited.

[0028]

EXAMPLES Next, other articles to which the badge technique according to the present invention is applied will be described. That is, the badge according to the above-mentioned embodiment adopts the above-mentioned structure in order to attach a magnet having a strong magnetic force to the soft resin portion, but this technique can be applied to other articles. is there. For example, the method of attaching the magnets described above can be applied to a magnet clip used when simply holding paper or the like on a whiteboard or another metal plate (wall). That is, the conventional magnet clip is formed by adhering a disk-shaped magnet (ferrite magnet or the like) having a flat surface of a relatively large area to a clip body (resin body) of a predetermined shape. When a strong rare earth magnet is adopted (the shape of the clip body itself can be made small in this case), the magnetic adhesion force is stronger than the adhesive force, and the magnet comes off the clip body.
Therefore, by adopting the method shown in the above-mentioned embodiment and forming a resin portion on the magnet by molding, and by coupling the clip body through the resin portion, a compact and strong magnetic force is adopted. Also in the case of doing, it is possible to prevent the magnet from coming off from the clip body. As described above, the method according to the present application can be variously applied to the clip body (magnet clip) and other members in which the magnet and the synthetic resin are adhered by adhesion.

[0029]

As described above, the present invention has the following effects. That is, since the badges according to claims 1 to 4 do not have a structure in which needle-like pins are provided on the back surface of the ornament, which has been mainly used in the past, there is a concern that the needle-like pins may cause injury. There is no. Further, as a decorative body, since a soft synthetic resin can be used instead of metal, with the structure without using the needle pin,
It has the effect that the badge can be used safely. In addition, by using a rare earth magnet with a strong magnetic force such as a neodymium magnet without using needle-shaped pins, it is possible to prevent the clothes from being damaged even when they are worn on clothes, etc. It is possible to provide a difficult badge. Furthermore, by providing a new method for fixing the magnet to the decorative body made of synthetic resin, it is possible to provide a badge in which the magnet is not easily detached from the decorative body even if a magnet having a strong magnetic force is used.

Further, the badge according to claim 5 has the following effects in addition to the above effects. That is, the magnet of the ornamental body protrudes from the ornamental body, and the magnetized portion of the mounting member is recessed from the surface of the mounting member. Deforms according to the fitting condition of the parts. Since the decorative body is attached in such a state, the decorative body has an effect of not being displaced from the attached position.

The invention according to claims 6 to 8 has the following effects. That is, the method of attaching a magnet to a synthetic resin member according to the present invention has an effect that the magnet can be firmly fixed even if the magnet having a strong magnetic force is fixed to the synthetic resin and the magnet is hard to be separated from the synthetic resin. I have it.
