Abstract

PROBLEM TO BE SOLVED: To enable a user to simply and securely put a shoe on and off a foot to be tightly in contact by one touch by preliminarily adjusting a fastening condition and making work after that repeatedly reproducible and to suppress dislocation between a foot and a shoe by using an elastic metal piece for the fastening part. SOLUTION: Troublesome work to orderly feed a shoestring for partially loosening for fastening a shoe and adjusting fastening force is required for putting a shoe on and off. If the work is idly carried out to bring a foot not tightly in contact with the shoe, it may cause fatigue and a shoe sore. It is hard work for a fat person who is hard to bend the body, an aged or child who is weak powered. This method is to preliminarily adjust a fastening condition to make work after that repeatedly reproducible. Thus the shoe can be simply and securely put on and off a foot by one touch and brought in tightly contact with a foot. An elastic metal piece is used for the fastening part to make the shoe quickly follow deformation the foot to suppress displacement between the foot and the shoe.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique for fixing and closely attaching shoes to a foot.

[0002]

2. Description of the Related Art A shoe is required to have a function of protecting the foot from an injury and a proper fit to the foot. If the foot and the shoe are not properly fitted, the movement of the foot is not sufficiently transmitted to the shoe as the wearing time becomes longer, and the lost momentum is accumulated as fatigue and the repeated rubbing causes the abrasion of the shoe. In addition, when the foot suddenly stops or changes direction while playing in the shoe, a large amount of force including the loss is required and the operation time is also lost.

[0003] Conventionally, in shoes, it is routinely performed that one shoelace threaded in zigzag in the left and right shoelace holes is appropriately tightened so as to be appropriately fixed and closely attached to the foot. With this method, the shoelaces cross each other, so the upper string presses the lower string, so if you cannot adjust the tightening force evenly in each hole, adjust the tightening force. It has a drawback in that it has to move a considerable length, and since the movement of the shoelaces is poor, it does not follow the deformation caused by the movement of the foot. In addition, with this method, it is necessary to loosen the shoelaces every time at rest or when returning home, and to feed the shoelaces again when tightening the shoes again. Further, the operation of tightening the shoelaces is a pain for those who are not good at bending down, such as old people and children who cannot easily tie the laces with strong force, or those who are obese.

Among the shoes currently on the market, which is adopted as a method of fixing the shoe to the foot with one touch, there is a method of fixing by entwining many J-shaped males with many U-shaped females. is there. Since this method is not a complete mechanical fastening method, slack is likely to occur, and the fastening force tends to decrease as the number of attachments and detachments increases, and durability remains a problem. There is a tightening method that utilizes the elasticity of rubber, but it has the same drawbacks.

As a special method, a thin bag-shaped air tank in a deflated state is put in the shoe, and after inserting the foot, air is pushed into the air tank by a simple air pump to separate the space between the shoe and the foot. There is a method of filling and fixing the space. Naturally, it is difficult to keep air with pressure fluctuations sealed for a long time with a simple structure, so it is often used for shoes used for a short time such as for sports. Also, since it uses an elastic body called air, it fits the foot, but this deforming function hinders the fixing force.

[0006]

SUMMARY OF THE INVENTION The present invention provides a simple and reliable method for attaching and detaching a shoe, which is carried out by tightening or loosening the traditional shoelaces currently used in many shoes. It's about changing to a method. In addition, during exercise such as walking or running, the shape of the foot is constantly changing due to muscle movement and skin expansion and contraction, but with the conventional method of fixing the foot with shoelaces, the shape of the shoe changes to the shape of the foot. It aims to solve the problem that it is difficult to follow quickly and strongly.

[0007]

SUMMARY OF THE INVENTION According to the present invention, a shoelace hole for each of the left and right sides is selected from a method for fixing shoes which is generally adopted at present, in which one long shoelace is passed through a plurality of left and right shoelace holes and tightened. Place a tightening device between them, connect the left and right shoelace holes and the holes of the tightening device with connecting metal fittings, pull the left and right shoelace holes evenly with the tightening device, and fix them to the foot. Further, in order to make the shoe follow the shape change of the foot, the connecting metal fittings of the left and right shoelace holes are made of an elastic body, so that a higher reaction speed and higher adhesion than the shoelace are obtained.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION At present, when the left and right shoelace holes are alternately sewn, tightened, and adjusted, the whole must be loosened.
Without connecting the left and right directly with the method of tightening the shoelaces of the book, attach one end of the connecting metal fitting to the left and right shoelace holes respectively and attach the other end to the independent pulling plate on the left and right respectively and connect each shoelace hole The attracting plate is connected to the tightening device and tightened in a lump to simplify the work of attaching and detaching shoes.

[0009]

[Embodiment 1] FIG. 1 shows an upper part of a shoe. Conventionally, one shoelace is alternately sewn into the left and right shoelace holes 6 and finally both ends are tied and fixed to the foot. In the tightening method of the present invention, the shoelace hole 6 and the holes 7 formed in the left and right attracting plates 1 and 2 are connected by the connecting fitting 5. Plural holes for connecting the attracting plates are opened to adjust the tightening condition. Reference numeral 9 denotes a folded-back portion, 1 and 2 are connected to 9 by a hinge 10, and they are folded and fixed by a lock of 8.

When taking off the shoes, the lock of 8 is removed, and the folded portion of 9 is raised and folded back and overlapped. 2
The area 9 and 9 expands and the width becomes loose so that the shoe can be easily removed. When putting on shoes, put the legs in the state where the overlapped parts are spread out, and by folding the parts 2 and 9, the left and right shoelace holes are attracted and the feet are fixed to the shoes.

Finally, the lock 8 is provided so that the folded portion does not bounce up and loosen. If the shape of the connecting metal fitting 5 is made of an elastic metal or the like, the shape of the connecting metal fitting 5 follows the deformation and the contact feeling is enhanced. In addition to the second embodiment, this method can be applied to many shoes by making several holes in the attracting plate for attaching the connecting fittings for adjusting the tightening force or changing the length of the connecting fittings.

[0012]

[Embodiment 2] FIG. 2 is a rotary locking method in which the attracting plate 1 for the right shoelace hole 6 and the attracting plate 2 for the left shoelace hole are overlapped, and a hole is formed in the overlapped portion. Tightening device 3
Fit in. When the rotation lever 4 of the tightening device is rotated, the left and right attraction plates 1 and 2 connected to the shoelace hole 6 and the connecting fitting 5 are pulled in opposite directions by the rotation lever 4 so that the left and right shoelaces are The holes 6 are drawn together and the shoe is fixed to the foot by selecting the position of the notch 8 which fixes the rotary lever.

When taking off the shoe, the left and right shoelace holes are unconstrained by turning the rotary lever from the cut position to the open side so that the shoe can be taken off. When putting on shoes, turn the rotary lever to the open side to make room for the foot, insert the foot, and rotate the rotary lever to the restraining side to fix the lever to the notch for fixing at an appropriate position. The shape of the rotary lever is decided by considering the balance of the applied force. Similar to the first embodiment, if the shape of the connecting fitting 5 is made of elastic metal or the like, the shape of the connecting fitting 5 can follow the deformation and the close contact feeling can be improved.

[0014]

As described above, the method for tightening shoes according to the present invention has the advantages that the structure and use are simple, no force is required, and the time is short. I think that the structure of the shoes itself is improving year by year, but it is important that you buy a good pair of shoes and use them, especially if you don't wear them well, and your body will be affected. In the current health boom, the importance of walking has been greatly reviewed. Finding the best shoes for yourself and proper usage are important for health. The method of fixing shoes by this method is simple, reliable, requires no force, and is easy to adjust, so we think that it will be pleasing to old people and children. Also, since there is no slackening factor, it can be used in sports shoes.
