[Detailed description of the device]

[0001]

[Industrial applications]

 This invention is provided with an attracting side having a built-in permanent magnet and an arc-shaped cross-section fitting groove for engaging the tip of a claw piece of the attachment member piercing the attachment member on the attachment surface side attached to the attachment member. And a magnetic attraction device that is attracted to the attraction side.

[0002]

[Prior art]

 Conventionally, when a magnetic hook is used as a hook for a handbag lid, for example, the suction side is attached to the outer wall surface of the body of the handbag, and the attracted side is attached to the inner wall surface of the lid and the outer wall surface of the body. It was attached at the position corresponding to the suction side.

An attaching member is provided on each attachment surface for attaching the attracting side and the attracted side to the attaching member, respectively. A typical attachment member is shown in FIG. 10, and the attachment member 3 having a structure in which the leg pieces 2 and 2 are connected to the base plate 1 is used.

Further, when the attracting side and the attracted side are respectively attached to the attachment member via the attachment member 3 as described above, the insertion holes of the leg pieces 2 are provided in the attachment member in advance. In view of the fact that the number of man-hours for mounting work is large and labor saving is difficult, a proposal has been made for the purpose of simply and surely mounting work of a stopper to a mounting member (JP-A-60-1 13904). . That is, Japanese Patent Laid-Open No. 60-113904 discloses that a plate-shaped mounting plate having a peripheral flange toward the inner side of the opening edge is provided on the surface of the magnetic hooking member that is in contact with the suction-side mounting member. The mounting member is mounted with the opening side facing the mounting member side, and the attachment member having a plurality of downward claws is pressed by the plurality of claws through the mounting member, and the tips of the plurality of claws are attached to the plate. A structure is proposed in which it is engaged and fixed in the tsuba.

Further, although the main purpose is not to simply and surely attach the stopper to the attaching member, in the Japanese Utility Model Application Laid-Open No. 58-60755, similarly, a magnetic hook is also required. It has been proposed to provide a fitting groove having an arc-shaped cross section for engaging the tip end of the claw piece of the attachment member that has pierced the attachment member on the side that abuts the attachment member on the attracted side.

[0006]

[Problems to be solved by devising]

 When the attracting side and the attracted side are respectively attached to the attaching member via the attaching member 3 as described above, the attaching work man-hours such as previously providing the attaching holes of the leg pieces 2 and 2 in the attaching member are required. In addition to the difficulty in labor saving, there is a problem in that, due to the structure, the bending and overlapping portions of the leg pieces 2 and 2 swell the mounting member and impair the appearance.

That is, the attachment structure of the attracted side A and the attachment member B (for example, the lid of the handbag) shown in FIGS. 10B and 10C will be explained. The leg pieces 2 and 2 of the attachment member 3 which are configured by 5 are inserted into the through holes 6 formed in the back skin 5 in advance, and the through holes 8 of the back washer 7 applied to the inner surface of the back skin 5 are formed. , 8 and the portions of the leg pieces 2 and 2 projecting from the back washer 7 are bent to form a superposed portion 9, and the superposed portion 4 covers the superposed portion 9. Therefore, it is unavoidable that the skin 4 bulges outward at the overlapping portion 9.

The overlapping portion 9 has been hit hard with a hammer or the like so that the bulge is minimized. However, the shape of the suction surface of the plate 49 and the cylindrical projection 50 that engage with the suction side C is determined. Was deformed and the magnetic adsorption performance was changed, which was not desirable.

In particular, the bulging due to the attachment of the attracted side A is formed on the outer skin of the lid of the handbag or the like, and therefore a solution has been desired.

The attachment structure on the adsorption side C is also the same, and the permanent magnet may be cracked by hitting with a hammer or the like so that the bulge becomes small.

On the other hand, in JP-A-60-113904 and JP-A-58-60755, the "peripheral collar" and the "fitting groove" provided on the attracted side are provided on the center side of the mounting surface. In addition, in order to provide these "peripheral collars" and "fitting grooves", it is necessary to add a member having a certain height to the mounting surface, and the height (thickness) on the attracted side is It was unavoidable that it exceeded a certain level. Therefore, even when these magnetic hooks are used for the lid of the handbag, etc., the bulging of the mounting member (for example, the lid of the handbag) is unavoidable, and the problem that the appearance is deteriorated cannot be solved. .

Further, in the conventional magnetic latching device, a structure has been proposed in which the surfaces are the same (flush) when the attachment member is attached to the attachment member (for example, Japanese Utility Model Publication No. 51-27). No. 697), in which a fitting groove having an arc-shaped cross section for engaging the tip end of the claw piece of the attachment member piercing the attachment member is provided on the side of the magnetic hooking device that abuts the attachment member on the attracted side. It was not related to the existing magnetic hooks. That is, with the main purpose of making the work of attaching the stopper to the attachment member simple and reliable, engage the tip of the nail piece of the attachment member that pierces the attachment member on the attachment surface side of the attracted side. Regarding the magnetic hook having the arcuate fitting groove in cross section, no magnetic hook that can make the surfaces the same (flush) when the attachment member is attached to the attachment member has not been proposed.

[0013]

It is an object to provide a magnetic hook having a structure.

The magnetic hook of the present invention which achieves such an object is an attraction side having a built-in permanent magnet, and a toe tip of an attachment member that pierces the attachment member on the attachment surface side attached to the attachment member. In a magnetic latching device having a curled edge with an arcuate cross section for engaging the ends, and a attracted side that is attracted to the attracted side, the attracted side has a flat portion in the center and a central flat portion. The curl edge having an arcuate cross section has a peripheral portion formed lower than the flat portion, and the curl edge having the arcuate cross section is provided on the inner side of the peripheral portion formed lower than the flat portion and the height of the upper end of the curl edge having the arcuate cross section is higher. The height of the central flat portion is equal to or less than the height of the central flat portion. In the above, the peripheral portion formed lower than the central flat portion on the attracted side is constituted by an annular tapered surface, and the attracting surface on the attracted side on the attracting side has a central flat portion and a peripheral taper portion. It can also be configured as. Further, in the above description, the curl edge having an arcuate cross section may be formed by another disc attached to the ferromagnetic plate constituting the attracted side. Further, in the above, the mounting surface side to be mounted on the suction side mounting member has a central flat portion and a peripheral portion formed lower than the central flat portion, and is formed lower than the central flat portion. Inside the peripheral portion, a curl edge with an arcuate cross section for engaging the tip of the claw piece of the attachment member piercing the attachment member is provided, and the height of the upper end of the curl edge with the arcuate cross section is equal to that of the central flat portion.
