Abstract

PROBLEM TO BE SOLVED: To provide a magnet holder which can be easily attracted to a magnetic material while preventing a placard from being damaged when being removed.SOLUTION: A capsule-like hollow body 1 is divided by a division plane vertical to a cylinder axis to form two divided hollow bodies 2 and 2. Pockets 3 are formed in positions facing each other of cylinder part inner surface sides of the respective divided hollow bodies 2, and a disk-like magnet 4 is stored in each pocket 3 so as to face an opening of the divided hollow body 2. Since magnets 4 are fixed on the cylinder part inner surface sides of the divided hollow bodies 2, this magnet holder reaches a position where it can be attracted to a magnetic material, by at most a half turn around the cylinder axis, so that the magnet holder can be quickly and easily fixed. Furthermore, since a placard P is in contact with a cylindrical surface, the placard P can be prevented from being damaged when being removed.

Description

  The present invention relates to a magnet holder for use in fixing a posting on a bulletin board made of a magnetic material.

  A magnet holder is often used when fixing a posting on the front door or bulletin board of a refrigerator made of a magnetic material. Many general magnet holders have a structure in which a disc-shaped magnet is fitted in a resin holder body. By inserting a posting between the magnet and the magnetic body, the posting is Fixed to a magnetic material. When removing the posting, the magnet holder is detached from the magnetic body with the other hand while supporting the posting with one hand. If you pull out the posting without removing the magnet holder by hand, the magnet holder will fall off the magnetic material, or the end of the magnet holder or magnet will rub against the posting, This is because scratches such as traces (such as streaks) that rub against each other remain, and the appearance may deteriorate.

  Therefore, for example, in the magnet holder described in Patent Document 1, the holder main body has a capsule shape, an elliptical spherical shape, a cylindrical shape, and the like, and a configuration in which a magnet is movably included in the space portion of the holder main body is adopted. Yes. In this way, when removing the bulletin board, the magnet holder slides little by little along the round shape of the capsule shape, etc. The possibility that the magnet holder comes off and falls is low. In addition, the holder body has a capsule shape, and a magnet is included in the holder body, so that generation of scratches caused by rubbing the holder body or the magnet with the display object is prevented as much as possible.

JP 2009-90483 A

  Since the magnet holder according to Patent Document 1 is provided in the holder main body so that the magnet can move freely, the magnet holder is not attracted to the magnetic body (the magnet holder is removed from the magnetic body). Is located at the lower part (bottom part) of the holder body by its own weight (see FIG. 1 of the same document). Even if the magnet holder is brought close to the magnetic body in this state, depending on the shape and size of the magnet holder, the distance between the magnet and the magnetic body will be too wide, and the magnetic force of the magnet will reach the magnetic body sufficiently. There can be nothing. Then, since this magnet is not attracted to the magnetic material side, the posted object cannot be fixed by the magnet holder. In this case, it is necessary to move the magnet appropriately from the lower part so that the magnetic force of the magnet reaches the magnetic body by shaking the magnet holder by hand.

  Accordingly, an object of the present invention is to make it possible to easily perform adsorption to a magnetic material while preventing a scratch from being generated when a posted object is removed.

  In order to solve the above problems, in the present invention, a magnet is fixed to the inner surface side of a cylindrical hollow body in which hemispherical portions are formed at both ends of the cylindrical portion, and the magnet is attracted to the magnetic body via the cylindrical portion. The magnet holder was configured to fix the posting.

  By fixing the magnet to the inner surface of the cylindrical part, the magnet (magnet holder) is attached to the magnetic body only by rotating the magnet holder slightly around the cylindrical axis so that the fixed magnet faces the magnetic body side. It can be easily adsorbed. Further, since the hollow body of the magnet holder is formed in a capsule shape, it is possible to alleviate the concentration of force at a specific location when removing the posting, and it is possible to prevent damage caused by this force.

  In the above configuration, the hollow body is divided into a plurality of divided hollow bodies by a dividing surface that crosses the central axis of the cylindrical portion, and the magnets are provided in each divided hollow body so as to face the dividing surface. The divided surfaces of the divided hollow bodies can be adsorbed by the adsorbing force between the magnets provided on the body so that they can be integrated into the capsule-shaped hollow body.

  In this way, the hollow body is divided into divided hollow bodies, and the divided hollow bodies can be appropriately integrated by the magnetic force of the magnet, so that, for example, when a large-sized display object is fixed, it is divided into divided hollow bodies. In this state, the both ends of the upper end of the posting are fixed. On the other hand, when the area of the posting is small, only one portion of the upper end of the posting is fixed in a state where each divided hollow body is an integral hollow body. The usage mode can be appropriately selected according to the purpose of use. The number of divisions can be changed as appropriate. For example, the hollow body may be divided into four hollow bodies so that the four corners of the posting can be fixed.

  In the structure which divides | segments the said hollow body and makes it a division | segmentation hollow body, a magnet can also be provided in the position which the cylindrical part inner surface side of the said division | segmentation hollow body opposes, respectively.

  By providing magnets at a plurality of locations of each divided hollow body in this manner, the number of attracted locations on the magnetic body increases, and thus the usability when fixing the posting with this divided hollow body is further improved. Further, when the divided hollow bodies are adsorbed to form an integral hollow body, the adsorptive force increases by the number of magnets increased, so that the integrated divided hollow bodies are unlikely to come apart, and the posting is fixed. Stability is improved.

  In this invention, the magnet was fixed to the cylindrical part inner surface side of the capsule-shaped hollow body. By making the hollow body into a capsule shape, when removing the posting, the concentration of force on the specific part is eased and the posting is prevented from being damaged as much as possible, and the magnet is fixed to the inner surface of the cylindrical portion By doing so, since the attracting action is exhibited only by moving the portion where the magnet is provided toward the magnetic body side, it is possible to easily fix the posting.

  One Embodiment of the magnet holder based on this invention is shown in FIGS.

  As shown in FIGS. 1 to 4, the magnet holder includes a capsule-shaped hollow body 1 in which hemispherical portions are formed at both ends of the cylindrical portion. The hollow body 1 has the same shape by a dividing surface perpendicular to the cylindrical axis. It is divided into two divided hollow bodies 2 and 2. The hollow body 1 is made of a resin material. Each of the divided hollow bodies 2, 2 has a pocket 3 formed at an opposing position on the inner surface side of the cylindrical portion, and a disk-like magnet 4 is accommodated in each pocket 3 so as to face the opening of the divided hollow body 2. Yes.

  One surface of the magnet 4 is an S pole 4s, and the other surface is an N pole 4n. In each magnet 4, both poles 4s and 4n face the same side (see FIG. 1). That is, among the opposing pockets 3, when the magnet 4 accommodated in one pocket 3 is the S pole 4s toward the outside of the cylindrical portion, the magnet 4 accommodated in the other pocket 3 is the N pole 4n toward the outside of the cylindrical portion. It becomes. The type of the magnet 4 is not particularly limited. However, since it is necessary to apply a magnetic force to the magnetic body through the cylindrical portion of the divided hollow body 2, it is preferable to employ a magnet 4 having a high attractive force such as a neodymium magnet.

  Ribs 5 are formed at intermediate positions along the inner surfaces of the cylindrical portions of both pockets 3 and 3 so as to stand on the cylindrical portion axis side while facing the hemispherical portion side. The rib 5 ensures the strength of the divided hollow body 2. In a state where the magnet 4 is housed, a lid 6 is provided at the opening of the divided hollow body 2, and is screwed into the screw hole 8 of the divided hollow body 2 with a screw 7.

  Instead of screwing the lid 6 with the screws 7 in this way, a fitting portion may be formed in the opening of the divided hollow body 2 and the lid 6 may be fitted into the fitting portion. If it does so, screwing work will become unnecessary and it can aim at reduction of manufacturing cost.

  When the two divided hollow bodies 2 and 2 provided with the magnet 4 are brought close to each other so that the magnetic poles 4s and 4n of the magnet 4 provided facing each other are in opposite directions, as shown in FIG. It can be set as the magnet holder which consists of the capsule-shaped hollow body 1 which mutually adsorb | sucks. Further, as shown in FIG. 5 (b), a cylindrical divided hollow body 2 provided with magnets is similarly provided between the divided hollow bodies 2 and 2 at both ends, and the hollow body 1 is used when the four hollow bodies 1 are used. It can also be divided. Of course, the number of divisions can be further increased according to the application.

  As shown in FIG. 6 (a), the magnet holder can fix the posting P with the integral capsule-shaped hollow body 1, while the two divided hollow bodies 2 as shown in FIG. 6 (b). It is also possible to fix the upper ends of the posting P in a state where it is divided into two. At this time, if the four-divided magnet holder shown in FIG. 5B is used, the four corners of the posting P can be fixed, and the stability is further improved.

  When fixing the posting P, the magnet 4 is fixed to the inner surface side of the hollow body 1 or the hollow part 2 of the split hollow body 2. It reaches the place where it can be adsorbed to the body and can be fixed quickly and easily.

  It is preferable that the divided hollow body 2 has its cylindrical surface in contact with the posting P because the damage to the posting P due to the divided hollow body 2 can be prevented. However, as shown in FIG. The posting P can be fixed so that the lid 6 of the divided hollow body 2 faces the posting P.

  When removing the fixed posting P as shown in FIGS. 6A and 6B, the posting P is pulled out from the magnet holder downward and forward with one hand. Then, this magnet holder slides in small increments with respect to the posting P while adsorbing to the magnetic body (rotation in the pulling direction and rotation opposite to this rotation (rotation toward the magnet attracting direction)). This posting P can be removed without removing or supporting the magnet holder with the other hand. Moreover, since the magnet holder and the posting P are in contact with the cylindrical surface of the hollow body 1 or the divided hollow body 2 and no force is applied to the posting P in a concentrated manner, the posting P is damaged when the posting P is removed. This can be prevented as much as possible.

  In each of the above embodiments, the pockets 3 for storing the magnets 4 are formed at opposing positions on the inner surface side of the cylindrical part. For example, the pockets 3 are formed at intervals of 90 degrees in the circumferential direction of the cylindrical part. A magnet 4 can be provided. In this way, when the cylindrical part of the hollow body 1 or the divided hollow body 2 is adsorbed to the magnetic body, the number of adsorbable portions can be increased, so that the posting P is quickly adsorbed to the magnetic body. Can be made.

  In each of the above embodiments, the hollow body 1 is divided by a dividing surface perpendicular to the cylindrical axis. However, the hollow body 1 is divided by a dividing surface slightly inclined with respect to the cylindrical axis. You can also If it does in this way, diversity will arise in the shape of the divided | segmented hollow body 2, and there exists a merit that the design property as a product further improves.

  As the shape of the hollow body 1, a spherical shape without the cylindrical portion, a cylindrical shape without the hemispherical portion, a spheroid shape, or the like may be employed instead of a capsule shape in which hemispherical portions are formed at both ends of the cylindrical portion. Even in the case of these shapes, fixing the magnet inside the wall surface of the hollow body 1 makes it easy to attract the magnetic material while preventing the posting P from being damaged, as in the case of the capsule shape. This is because you can get to.
