Description

  The present invention relates to a shoe using a magnet such as a magnet tape or a magnet button as a fastener.

  Conventionally, as a shoe fastener having an opening at the front portion of the hood, a shoelace has been generally used, but in recent years, various types using a hook-and-loop fastener have been known. This type of shoe has one end of a band with a piece of hook-and-loop fastener bonded to one side of the hook opening, and is detachably bonded to a pair of hook-and-loop fasteners provided on the opposite hook and It is the structure which clamp | tightens the collar part of this suitably. However, when a hook-and-loop fastener is used as a fastener, there is a problem in that dust or lint etc. adheres to the protruding portion of the hook-and-loop fastener, resulting in a decrease in adhesive strength or a poor appearance.

Japanese Patent Laid-Open No. 11-4704 JP 2002-28006 (P2002-28006A)

  The problem to be solved is to provide a shoe fastener that is easy to attach and detach, and that is free from dirt and lint.

In order to solve the above-mentioned problem, the shoe of the present invention is provided with a tightening portion on the inner cover side or the outer cover side of the cover, and the tightening portion instead of a conventional surface fastener, As a shoe fastener, a magnet member made by mixing magnet powder with rubber, a magnet member that can be joined by a magnet button, or the like was made openable and closable.
As the magnet member to be used, it is desirable that the coercive force of at least one magnet member in the pair is 80000 A / m or more and the saturation magnetic flux density is 0.1 T or more. Examples of such materials include SmCo-based magnets mainly composed of Sm ₁ Co ₅ and Sm ₂ Co _17, NdFeB-based magnets mainly composed of Nd ₂ Fe ₁₄ B ₁ , Ba ₁ Fe ₁₂ O _19, and Sr _1. Examples thereof include hard ferrite such as Fe ₁₂ O _{19 and the} like, and each sintered magnet or a plastic magnet produced by mixing with a plastic material is used. When such a hard magnet is used as a pair of magnets, only one side has a soft magnetic material made of Fe, Ni or the like, or an oxide soft magnetic material such as MnZn ferrite, and also has magnetic properties such as SUS304. The same effect can be obtained even with a material such as stainless steel. As magnets, rare earth magnets are high, and in the case of sintered magnets, cracks and chips are likely to occur, so it is preferable to use plastic magnets.
In a button made of a tape or a magnet made using a magnet as described above, the magnetization vector should preferably be perpendicular to the surface where the pair is attached, and in some cases NS may be present on the surfaces of both magnets. Magnetization may be performed by dividing into regions so as to coexist. For example, in one magnet, NSNS with respect to the longitudinal direction of a button or a tape composed of N or N on the outside, S on one side of the pair, S on the center, and N on the outside They are magnetized as if they were lined up.
By covering the surface of the magnet button or the surface of the magnetic tape made of magnet with a vinyl or cloth of 1 mm or less, when magnetic iron or the like adheres, the magnet or iron is removed by removing the vinyl or cloth on the surface of the magnet. Therefore, it is preferable to attach a nonmagnetic cover to the surface of the magnet.
Specifically, a tightening portion is provided on the inner sheath side or outer sheath side of the sheath, and holes are formed in the magnet tape and magnets to be attached thereto and fixed through the thread. Alternatively, a magnetic tape or a magnet may be bonded and fixed to the tightening portion, or may be fixed in a state of being put in a cloth made of a fiber such as nylon or polyethylene. Similarly, the same effect can be obtained by thermally fusing the magnet member. A similar effect can be obtained by forming the tightening portion with a fiber made of a ferromagnetic material.

  Unlike shoelaces and hook-and-loop fasteners that have been used as shoe fasteners in the past, the present invention uses a magnetic tape or a magnetic button as a shoe fastener so that the shoe of the present invention can be used by people with physical disabilities or elderly people. Not only is it easy for people to wear, but it is easy to attach and detach.

  As a shoe tightening structure, one end of a band is fixed to one of the both hoods along the heel opening of the shoe, and the other end of the band is covered with a magnetic tape as a fastener on the heel part where it overlaps, or A magnet button is attached, a tightening portion is provided, and it is configured to be detachable.

A magnetic tape 5 is attached to an appropriate position on the back surface of the narrow tightening portion 3, and a magnet tape 6 is also attached to an outer cover portion overlapping the narrow tightening portion 3 so that they are attracted to each other by magnetic force. did.

As a pair of magnets 5.6 shown in Example 1, plastic magnets having different magnet coercive force and saturation magnetic flux density were produced, and the force applied by the pair of magnets was evaluated, and the results are shown in the table. The saturation magnetic flux density was adjusted by changing the amount of polyphenylene sulfide resin by changing the composition of Ba _1-x Zn _x Fe ₁₂ O ₁₉ as the composition of barium ferrite as one magnet and changing the coercive force. On the other side, a tape made of an acrylic resin containing 50 wt% pure iron was used as a constant. As a result, it is understood that at least the coercive force is 80000 A / m or more and the saturation magnetic flux density is 0.1 T or more.

The shoe cap 9 is provided with a tightening portion 10 that tapers toward the tip starting from the inner waist of the toe portion, and a magnet button male piece 14 is attached to the back surface of the tightening portion 10 at an appropriate position. And the magnet button female piece 15 was also attached to the outer cover part which overlaps with the tightening part 10, and it mutually attracted | sucked by the magnetic force.

  FIG. 7 is a perspective view of a shoe having a tightening structure according to the sixth embodiment. FIG. 8 is a perspective view of the shoe with the tightening portion 16 of Example 6 in an open state. In FIG. 7, 18 is a cover made of cloth, synthetic leather, leather or the like, 19 is a bottom formed of rubber, synthetic resin or leather, and the bottom 19 is attached after the cover 18 is suspended. By forming a shoe. The hood 18 is provided with a mouth opening substantially corresponding to the ankle, and further provided with a heel tightening portion opening edge 20 that opens to the heel portion side. In the shoe of the present invention, the string 17 is attached to the toe side of the heel tightening portion opening edge 20, and the magic buttons 22 and 23 are attached to the wearing mouth side, respectively, and the heel portion is tightened for use. .

  The shoe of the present invention formed as described above is used by tightening the heel with the string 17 and the tightening portion 16. That is, when the shoe is worn, the surface tightening portion 16 is removed, the string 17 is unfastened and loosened, the foot is inserted, and the strap 17 is first tightened so as to fit the foot sufficiently. 22 and 23 are engaged and fixed magnetically.

  When the shoe is taken off, it can be easily done by removing the tightening portion 16 and opening the opening edge 4A from the mouth. The tightening portion 16 can detachably open and close the opening side of the heel tightening portion opening edge 20, but even if the toe side is tightened by the string 17, the shoe can be removed by simply removing the tightening portion 16. It can be taken off, and when the shoe is put on again, it can be performed only by engaging the tightening portion 16.

  In the illustrated example, three eyelets are provided on both sides of the eyelid tightening portion opening edge 20, and the string 17 is inserted and tightened there. The base end of the toe side of the string 17 is positioned in the vicinity of the base of the fingertip of the hood 18 as in ordinary shoes. However, when the string 17 is used, a fit cannot be obtained unless this part is sufficiently tightened. When tightening the heel only with the string as in the conventional case, even if you try to pull the string closer to the end on the side of the mouth, it will not be tightened sufficiently to the base end of the string. Having to loosen the string and gradually tighten from the proximal end is a cumbersome task that is often experienced.

  In the present invention, by using the string 17 and the tightening portion 16 in combination, the length of the string 17 can be made relatively short and the number of eyelets can be reduced. If a material such as hard leather is placed on the base, the base end of the string cannot be sufficiently tightened. In the present invention, in consideration of such points, even if other parts are made of a hard material, a soft material such as cloth or soft leather is arranged at least in the vicinity of the finger base of the hood 18. The base end is sufficiently tightened by the tightening operation of the string 17. Of course, the present invention can be applied to a wide portion including the vicinity of the finger base of the cover 18 or the entire cover 18 made of a soft material.

  In the above embodiment, an example is shown in which the present invention is applied to a short shoe-like sneaker, but the present invention is not limited only to such a shoe, and also to a deep shoe-like shoe having a higher mouth. The present invention can also be applied to shoes having a tip made of metal or synthetic resin on the toe. In particular, in a shoe with a tip attached to the toe, if the foot moves in the shoe, it is easy to cause a foot contact with a hard tip, but this structure prevents the foot contact. It is also possible.

  In the example shown in the figure, the string 17 is inserted into the left and right three eyelets, but it is also possible to place the eyelets in two right and left eyelets or four or more eyelets. In addition, the tightening portion 16 can adopt the same configuration as that used for ordinary shoes, and adopt and use an appropriate size and shape that occupies the space between the mouth and the string 17. be able to.
