(Embodiment 1)
FIG. 1 is a perspective view showing a folded state of a sheet body 2 to which an eyelet 1 is attached according to an embodiment of the present invention, and FIG. 2 is an exploded perspective view showing an attachment state of the eyelet 1. The sheet body 2 of the present embodiment exemplifies what is realized as a so-called blue sheet used for temporarily covering a construction site or the like and preventing rain leakage of a roof, but it is thick. At the construction site, a sheet body used as a dustproof / soundproof sheet may be used, and the eyelet 1 is held at a position where the sheet bodies 2 such as corners and edges are folded and overlap each other. A string or a binding band may be passed through the grommet and tied to a large area, or tied to a scaffold or a house.

As shown in FIG. 2, the eyelet 1 of the present embodiment illustrates a double-sided eyelet in which the eyelet main body 3 and the washer 4 are combined, but the opposite side of the tubular main body is used without using the washer 4. A single-sided eyelet that expands the diameter may be used. Therefore, the eyelet 1 of the present embodiment has a hole 22 formed in a corner portion 21 or an edge portion of the sheet body 2 from the surface of the sheet body 2 to the tubular portion 31 of the eyelet body 3 as indicated by an arrow 23. After the washer 4 is applied from the back surface side as indicated by the arrow 24, the tip portion 311 of the tubular portion 31 is punched to sandwich the peripheral edge portion of the hole 22.

It should be noted that the eyelet 1 of the present embodiment has magnetic property. Specifically, for example, when a plurality of eyelets are provided at positions where the sheet bodies 2 such as corners and edges overlap each other in a folded state, and are used in pairs or in pairs. All or some of the eyelets contain a magnet component, or a magnetic material such as iron is magnetized by applying a strong electric field or a strong magnetic field, while the magnet component is contained or magnetized. When only a part of the pigeons is present, the remaining pigeons can be made of a magnetic material such as iron so that they can be magnetized with each other.

With this configuration, when the eyelets 1 approach each other to the extent that they are affected by the magnetic force, they exhibit a new function of attracting each other. Moreover, even a single substance can be adsorbed on an iron plate or the like. As a result, in the sheet body 2, when the corners and edges forming a pair or a pair are combined and folded, the corners and edges naturally fit together, and once they are joined, even if the hands are released. Convenience can be improved when the large-area sheet body 2 is folded and stored without being separated.

It should also be noted that when the eyelet 1 is made of a magnet, the magnet may be a multipolar magnet or an anisotropic magnet, but in the present embodiment, it is made of an isotropic magnet. Here, the isotropic magnet cannot be clearly polarized to the SN from the outside, and therefore does not repel each other and only attracts the magnet. Therefore, in the sheet body 2, by using the isotropic magnet eyelets 1 for the corners and edges forming a pair or a pair, the convenience at the time of folding can be further improved. For example, when the sheet body 2 is rectangular, the eyelets 1 can be adsorbed to each other regardless of whether they are folded in the horizontal direction, in the vertical direction, or in the diagonal direction.

Of the single-sided eyelet and the double-sided eyelet, due to the above-mentioned magnetic attraction, the single-sided eyelet itself needs to contain a magnet component or be formed of a magnetic material, but like the eyelet 1 of the present embodiment. In addition, in the double-sided eyelet, at least one of the eyelet body 3 and the seat 4 formed by the combination may contain the component of the magnet or may be formed of a magnetic material. However, it is preferable that the washer 4 contains a magnet component and the eyelet body 3 is made of a magnetic material, particularly when both are made of a magnetic material or a magnet.

That is, the eyelet body 3 that is plastically deformed by a punch is formed of a magnetic material such as iron, and the portion of the washer 4 that is not plastically deformed contains a magnet component. By doing so, the strength of the eyelet body 3 part can be secured without impairing the magnetic force, and the material of the washer 4 part is selected by giving priority to the magnetic attraction force rather than the strength and the ease of deformation. Can be and is suitable.

On the other hand, in the sheet body 2, the eyelet 1 that performs magnetic attraction as described above is formed when the eyelet 1 for inserting a connecting member such as a string or a binding band is fitted into the hole 22 that penetrates the front and back surfaces. By using the above, the sheet body 2 can be easily folded, which is preferable. In particular, by providing the eyelet 1 on the peripheral edge portion, the corner portion and the edge portion naturally fit together, and a sheet body that is easy to fold can be realized. As the sheet body 2 provided with the eyelets 1, it is preferable that the dustproof / soundproof sheet has a large area and is easy to fold.

FIG. 3 is a cross-sectional view of the eyelet 5 according to another embodiment of the present invention. In the above-mentioned eyelet 1, all or some of the eyelets contain a magnet component or are magnetized, and the magnet component is contained or magnetized only in some eyelets. The remaining eyelets are made of a magnetic material such as iron to give them mutual magnetic properties. Therefore, the base material itself of the eyelet body 3 and the washer 4 contains the component of the magnet or is made of a magnetic material. However, in that case, the strength of the base material itself may decrease.

Therefore, in the eyelet 5 of the present embodiment, the base material and the magnet or magnetic material are separated and formed. Specifically, FIG. 3 shows a cross section of the single-sided eyelet 5, but the base material 50 includes an inner tubular portion 51 and a flange portion 52 extending radially outward from one end of the tubular portion 51. It is configured to include an outer cylinder portion 53 formed by folding back the outer peripheral edge of the flange portion 52 substantially parallel to the tubular portion 51. Then, after passing the tubular portion 51 through the hole 22 of the sheet body 2, the diameter of the tip side 511 of the tubular portion 51 is expanded by a punch to sandwich the sheet body 2.

Therefore, by using the tubular portion 51 as the inner wall, the outer cylinder portion 53 as the outer wall, and the flange portion 52 as the bottom portion, and deepening the tubular portion 51 and the outer cylinder portion 53, an annular recess 54 is formed inside. The granular magnet 55 is injected and solidified in a state of being dispersed in a resin 56 made of silicone rubber or the like, using that as a storage space. In the case of a magnetic material, iron particles or the like may be used instead of the magnet 55. In this way, even if the base material 50 is formed of non-magnetic stainless steel that is resistant to plastic deformation or a resin that is deformed by heat, the magnet 55 can be incorporated to provide magnetic property. The resin 56 is preferably bisphenol-free.

Furthermore, in the eyelet 5 of the present embodiment, the lid 57 is provided so as to cover the recess 54 which is the storage space, that is, the filled granular magnet 55 and the resin 56. By filling the granular magnet 55 and the resin 56 in a liquid state, when they solidify, they are fixed (adhered) to the base material 50, but if they are preformed, they are formed in the recess 54. By pressing and fixing the sheet body 2 with the lid 57 after fitting, the sheet body 2 is sandwiched between the sheets and the sheet body 2 is sandwiched between them so that the sheet body 2 does not shift and workability can be improved.

(Embodiment 3)
FIG. 4 is a cross-sectional view of eyelet 6 according to still another embodiment of the present invention. In the case of double-sided eyelets, a ring-shaped, string-shaped, or rubber (ring-shaped in FIG. 4) magnet 65 may be provided between the eyelet main body 60 and the washer 67 as in the eyelet 6. Similar to the eyelet 5 described above, the eyelet body 60 has an inner tubular portion 61, a flange portion 62 extending radially outward from one end of the tubular portion 61, and a tubular portion 61 having an outer peripheral edge of the flange portion 62. It is configured to include an outer cylinder portion 63 formed by folding back in substantially parallel with the above. The ring-shaped magnet 65 is fitted into an annular recess (storage space) 64 having a tubular portion 61 as an inner wall, an outer cylinder portion 63 as an outer wall, and a flange portion 62 as a bottom. After the sheet body 2 is sandwiched between the washers 67, the tip portion 611 of the tubular portion 61 is punched and fixed, and the locking claw 68 hangs down from the outer peripheral edge portion to the magnet 65 side. This prevents the magnet 65 from being displaced.

In the case of double-sided eyelets in this way, since the eyelet body 60 and the washer 67 are combined to form a double-sided eyelet, the shape is formed in advance so that an annular recess (storage space) 64 is formed between them. By sandwiching a ring-shaped magnet 65 between them when assembling with a punch, the magnetic property can be obtained. The eyelet body 60 and / or the washer 67 may be either a non-magnetic material such as resin or a magnetic material such as metal. Further, unlike the eyelet 3, a multi-polar magnet can be used by using a single magnet 65 instead of a granular magnet 55 dispersed in the resin 56. For example, a strong magnet such as a neodymium magnet can be used. Can be used.

(Embodiment 4)
FIG. 5 is a cross-sectional view of the eyelet 7 of another embodiment of the present invention. The eyelet 7 is a double-sided eyelet, and the eyelet body 70 and the washer 71 are each filled with a resin 56 in which the magnet 55 is dispersed, and the lids 72 and 73 are covered with the eyelet 7. With this configuration, eyelets that are strongly magnetized can be realized. By dispersing and solidifying the granular magnet 55 in the resin 56 in this way, both the single-sided eyelet 5 and the double-sided eyelet 7 can have the magnetic property.

(Embodiment 5)
FIG. 6 is a cross-sectional view of eyelet 8 according to still another embodiment of the present invention. The eyelet 8 is similar to the eyelets 5 and 6 described above, and the same reference numerals are given to the corresponding portions, and the description thereof will be omitted. In the eyelet 8, a ring-shaped magnet 65 is used for a single-sided eyelet, and a lid 57 is not used for fixing the magnet 65. In the eyelet body 50a, a claw having a tip portion 531 of an outer cylinder portion 53 protruding inward. 58 is to be used. It is preferable that the claws 58 are evenly provided at a plurality of locations in the circumferential direction. By forming the tip of the claw 58 on the hypotenuse 581 that protrudes inward as it approaches the flange portion 52, when the magnet 65 is pushed in, the hypotenuse 581 is expanded by the magnet 65 and is outward from the flange portion 52. When the tubular portion 53 is elastically deformed and the magnet 65 passes through the hypotenuse 581, the deformation is released and the magnet 65 is locked by the claw 58.

Even with this configuration, the magnet 65 does not shift when the sheet body 2 is sandwiched and punched, and workability can be improved.

(Embodiment 6)
FIG. 7 is a perspective view of the belt 9 according to another embodiment of the present invention. In the above description, an example in which eyelets 1, 5, 6, 7, and 8 are applied to the seat body 2 is shown, but in the present embodiment, the eyelets are provided at both ends of the belt. Then, the central portion 91 of the belt 9 formed in the longitudinal strip-shaped body is used by being hooked on the pipe 12 which is the object to be engaged, and is folded back by the pipe 12 so as to be paired near both end portions. The attached eyelets 1, 5, 6, 7, and 8 are magnetized with each other. As a result, the holes 10 of the eyelets 1, 5, 6, 7, and 8 communicate with each other to form hook holes. In the example of FIG. 7, the head 13 of the wire hanger is hooked in the hole 10.

Therefore, by hooking the belt 9 on a stick or a protrusion somewhere and folding it back, a band-shaped body in which both ends are attracted to each other can be formed, and the eyelets 1, 5, 6, 7, and 8 are covered. Since the hole 10 is open, it becomes possible to suspend an object to be engaged that can pass through the hole 10. In this way, the object to be engaged can be easily hung from the rod or the protrusion somewhere. For example, it is effective when the hanger (13) is hooked on a pipe 12 or the like near the ceiling when traveling. Further, the belt 9 is hooked on the scaffolding pipe at the construction site, and the holes 10 and the holes 1, 5, 6, 7, and 8 of the eyelets of the other seat body 2 are connected with a string to form the seat body 2. You can also stretch it.

Here, as an example in which the magnet is provided on the eyelet, for example, Japanese Patent Publication No. 6-32907 is shown, but the magnet is attached to the eyelet or the magnet is attached to another object with the eyelet. It is used for magnetizing, and does not adsorb eyelets 1 to each other as in the present application.
