Abstract
Description
本発明は、下駄や草履やサンダルなどの鼻緒付き履物にて、一般ユーザが特定の挿げ具を用いずに、素手で簡単に鼻緒を挿げ替えることが出来る鼻緒と、該鼻緒が挿げられる鼻緒付き履物の台と、該鼻緒と該台で作られた鼻緒付き履物などに関する。 The present invention relates to footwear with sandals such as clogs, sandals and sandals, which can be easily replaced with bare hands by a general user without using a specific insertion tool. The present invention relates to a footwear with a nose and a footwear with a nose made of the foot and the foot.
従来の鼻緒付き履物は鼻緒を台に挿げる際、挿げ具など専用の治具を用いたり、鼻緒を挿げるにおいて専門的なノウハウが求められ、製造工場で先に鼻緒を台に挿げて出荷するか、鼻緒付き履物を販売する店で台に鼻緒を挿げて販売したり修理する現状にある。
この状況では、ユーザは鼻緒および台の色柄の組合せを厳選して購入する必要があり、当初は良いと思って購入したものであっても、服装が変わると似合わず残念な思いをすることが多い。和鼻緒の下駄に多いのが購入当初は鼻緒がきつくて足が痛く、使い続ける間にゆるくなるパターンであり、足に合わなくなったり鼻緒が傷むなど、鼻緒を挿げ替えたい場合には専門の店へ依頼するしかない。
他方、顧客のニーズが多様化する現代においては、一般的な履物においてもオリジナリティーのある履物が求められており、近年では自分独自のオリジナル性を求めて購入後にデコレーションできる履物が一大ブームとなった。履物を使うときのシチュエーションやファッションに合わせて異なるイメージの履物を色々に持っておくことが理想であっても、家庭や家計の事情、保管場所やセンスがなくて決めかねる、ファッションコーディネートしたくても服装によって合う合わないがあるから無難な履物を少数使いまわすしかない状況の人も多い。そんな状況にあっても、履物にファッション性を求める人は個性的な飾りが付いていたり珍しい色やデザインの履物を持つことで自己主張をしたい人も多く、鼻緒付き履物においても、デザイン性が良く個性的でコーディネートし易い鼻緒付き履物があれば人々に喜ばれるし、購入後に一般ユーザ先においてイメージチェンジできる履物があればなお更理想的で、鼻緒付き履物の台や鼻緒を簡単に交換したり挿げ替えられる必要性が、潜在的に発生している状況にある。
Conventional footwear with a umbilical cord requires special know-how in using a special tool such as an insertion tool when inserting the umbilical cord into a table, or using a lanyard first in a manufacturing factory. At the store that sells footwear with umbilical cords, it sells and repairs with the umbilical cords inserted into the table.
In this situation, the user needs to carefully select a combination of lanyard and pedestal color patterns, and even if it was originally purchased as good, it would be unfortunate that it would not suit as the clothes changed. There are many. The most common type of Japanese clogs are clogs at the beginning of purchase, painful legs, and loose patterns while you continue to use them. There is no choice but to ask the store.
On the other hand, with the diversification of customer needs, original footwear is also required for general footwear. In recent years, footwear that can be decorated after purchase in pursuit of its own originality has become a huge boom. It was. Even if it is ideal to have various footwear with different images according to the situation and fashion when using footwear, I want to make fashion coordination that I can not decide without circumstances of home and household, storage place and sense However, there are many people who have no choice but to use a few safe footwear because they do not match each other. Even in such a situation, many people who want fashion in footwear have a unique decoration or want to assert themselves by having footwear with unusual colors and designs, and even in footwear with nose, the design is People will be pleased if they have good, unique and easy-to-coordinate footwear, and it will be even more ideal if there is footwear that can be re-imaged by general users after purchase. There is a potential need for replacement.
特許文献1(特開平11−164709)は特定の挿げ具を用いずに、一般ユーザが鼻緒を簡単に交換可能とする先行技術である。
特許文献1では、鼻緒の前緒に第1係止具と第1保持体を設けてねじ止めで基台に固定し、鼻緒の後緒については第2保持体に長さの異なる位置で係脱可能な係止片を設けて、後緒の先の係止片を係止することで鼻緒を基台に固定するとともに鼻緒の長さ調整を可能としている。これにより一般ユーザでも鼻緒を挿げることを可能にし、係止片を掛ける位置で鼻緒の長さ調整も可能である。
しかしながら、本方式は基台の穴に鼻緒を通しただけでは鼻緒の端が基台の裏側には留まらず、後緒を固定するには基台を裏側に返してから行う必要があるため、固定作業の途中に鼻緒が表側へ抜け落ちてしまう可能性がある。
鼻緒の固定の仕方については、前緒だけを係止する場合はねじ止めで容易ではあるが、鼻緒が人の足で基台の表側へと引っ張られているときは基台裏側に設けた長溝に長形の袋ナットが嵌合していたとしても、履物を使用していないときは袋ナットが長溝から地面のほうへ抜け出る可能性があり、とかく雄ねじと雌ねじの組合せは振動により緩むものであるため確実な固定とは言えない。後緒においては、両側の緒を中央に引き寄せて第2保持体の係止片のフック状に輪(鼻緒の先の係止片)を引っ掛けねばならず、係止作業中に挿入したはずの後緒の片方でも表側へと抜け出れば手間取るし、フック状の先端に輪をかけるときに中央へと引き寄せる力が必要な割に、係止し終えた輪はフック状の係止の折り曲げ部に落ち着くしかないので、きつく締めたはずの鼻緒が微妙に少し緩んだ状態で基台に固定されて完了とせざるを得ない。
且つ、後緒を係止する第2保持体は基台の中央で両側の後緒に引き合いされる状態で鼻緒を係止するしかなく、2本の後緒は均等の長さで基台に固定されることになり、ユーザの足の甲の高さや変形などに合わせて後緒の左右の長さを別々に調整することはできない。
Patent Document 1 (Japanese Patent Application Laid-Open No. 11-164709) is a prior art that allows a general user to easily replace a chord without using a specific insertion tool.
In
However, this method does not stay on the back side of the base simply by passing the cord through the hole in the base, and it is necessary to return the base to the back side in order to fix the back, There is a possibility that the thong will fall out to the front side during the fixing work.
As for the way to fix the cord, it is easy to screw it when locking only the beginning, but when the cord is pulled to the front side of the base with the human foot, a long groove provided on the back side of the base Even if a long cap nut is fitted, the cap nut may come out of the long groove toward the ground when footwear is not used, and the combination of male screw and female screw is loosened by vibration anyway. It cannot be said to be secure. In the latter part, the cords on both sides must be pulled to the center to hook the ring (the locking piece at the tip of the nose) into the hook shape of the locking piece of the second holder, and it should have been inserted during the locking operation. Even if one of the back part comes out to the front side, it takes time, and the ring that has been locked is the hook-shaped bent part of the hook, although it requires a force to pull it to the center when hooking the hook-shaped tip Because it has no choice but to settle down, it has to be completed after it is fixed to the base with the chord that should have been tightened slightly slightly loosened.
In addition, the second holding body that locks the back has only to lock the nasal cord in the state of being attracted to the back of both sides in the center of the base, and the two backs are equal in length to the base. It will be fixed, and the left and right lengths of the back cannot be adjusted separately according to the height or deformation of the instep of the user.
次に、特許文献2(特表2013−509246)は、一般ユーザにて特定の挿げ具を用いずに対応する履物の台に鼻緒(当文献ではストラップ)を簡単に挿げられる特徴を持っている。
しかしながら、特許文献2の鼻緒の端は各々複数の分離可能な形状で構成され、鼻緒の端(当文献の分離可能部)を一片ずつ数回に分けて操作しながら台の穴に挿入する必要があり、一片を穴に入れるごとに穴は窮屈になり、分離可能部を押したり引いたりしながら穴の定位置に分離可能部があるべき姿に形状を落ち着けるには時間を要し、履物の台に設けられた3つの穴に鼻緒を固定し終わるには「穴数×複数回の挿入」が必要で、鼻緒の固定作業に手間がかかる。
また、この鼻緒は形状が複雑になることから鼻緒の製造単価が高くなると同時に、台の前方に複数の穴を設けることでセット位置によって鼻緒の長さを変更できるとされているが、一般的に鼻緒付き履物の前方に、使われていない穴が見えるのは体裁が悪いうえに、負荷に耐えるだけの肉厚が複数の穴同士の間に必要なため、鼻緒は大雑把な長さ変更しかできないなど、いろいろな問題を抱えている。
Next, Patent Document 2 (Special Table 2013-509246) has a feature that a general user can easily insert a cord (a strap in this document) into a corresponding footwear table without using a specific insertion tool. ing.
However, the ends of the umbilical cord of
In addition, because the shape of the cord is complicated, the production cost of the cord is increased, and at the same time, the length of the cord can be changed depending on the set position by providing a plurality of holes in front of the table. In addition, it is not good to see unused holes in front of the footwear with nose, and it is necessary to change the length of the nose because the wall thickness is enough to withstand the load. We have various problems such as being unable to do so.
また、特許文献3(実用新案昭56−2804)は、ゴム素材の履物の台に鼻緒を挿げる(当文献では立てる)装置であり、一般的にビーチサンダルなどに用いられる鼻緒とその台が図示されている。大きな円形である鼻緒の突出部を装置で挟持し、台に設けられた小さな穴に機械の力で押し込むことによって、大きな鼻緒の端は台の小さな穴から抜け出ることができず鼻緒が台に固定される。
ゴム素材など適度に柔軟性がある台に鼻緒の端を押し込むには、鼻緒の端が台の穴より大きくても、台の穴が横に押し広げられて機械的な力も相まって鼻緒を挿げて固定されるわけだが、いったん台に挿げられた鼻緒は安全性のためにも容易には抜けないように設計されているため、履物には鼻緒を取り付けた状態で販売するしかないのが実状である。この鼻緒を交換する必要があったとしても、強大な力で何とか鼻緒を引き抜けたとしても台の穴が破損または広がって再び鼻緒を挿げられないし、鼻緒自体は千切れるか器具で端を切り離すしかなく、履物の台や鼻緒は再利用することが困難である。
本発明はこれらに対して、生産性のある簡単な構造の鼻緒形状と、鼻緒付き履物の台にて、一般ユーザで簡単に鼻緒の挿げ替えが行える構造を提供するものである。
Patent document 3 (utility model Sho 56-2804) is a device that inserts a snare on a footwear made of rubber (it stands in this document). Is shown. By holding the projecting part of the large umbilical cord with a device and pushing it into the small hole provided in the table with the power of the machine, the end of the large umbilicus cannot escape from the small hole in the table and the lanyard is fixed to the table Is done.
In order to push the end of the cord into a moderately flexible base such as rubber material, even if the end of the nose is larger than the hole in the base, the hole in the base is pushed sideways and mechanical force is combined to insert the cord However, once the umbilical cord inserted into the table is designed so that it can not be easily removed for safety reasons, the footwear must be sold with the lanyard attached. It's real. Even if it is necessary to replace the cord, even if it is pulled out with great force, the hole in the base is damaged or widened, and the cord cannot be inserted again. There is no choice but to recycle the footwear platform and cord.
In contrast, the present invention provides a structure in which a nasal cord having a simple structure with high productivity and a footwear with a umbilical cord can be easily replaced by a general user.
鼻緒付き履物の鼻緒は、一般的にはユーザ側で鼻緒を挿げることが難しく、履物屋に履物を持ち込んで挿げるのが常である。つまり、いま市場に出回っている鼻緒付き履物は、鼻緒を台に挿げる場合には挿げ具と称する独特な治具を用いたり、専門職の勘で鼻緒の長さの調整をしながら鼻緒を固定する特殊な技術を要する環境にある。
先行資料の特許文献によれば、ユーザで鼻緒が挿げられる発明品もあるようだが、その構造は複雑で、素人が鼻緒を挿げるにはまだ難しさが残っているようである。
In general, it is difficult for the user to insert the umbilical cord in the footwear with the umbilical cord, and it is usual to bring the footwear into the footwear store and insert it. In other words, footwear with cords that are currently on the market use a unique jig called an insertion tool when inserting the cord on the table, or while adjusting the length of the cord with professional intuition. It is in an environment that requires special techniques to fix the umbilical cord.
According to the patent document of the prior document, it seems that there are some inventions in which the user can insert the cord, but the structure is complicated, and it seems that the difficulty still remains for an amateur to insert the cord.
特に、鼻緒付き履物の鼻緒と台は一般ユーザに対して個別に販売される状況では無く、履物屋で気に入る鼻緒と台を指定してオーダーメードで挿げてもらうか、既に鼻緒が挿げてある鼻緒付き履物の完成品の中から、見た目と履き心地などを考慮し、出来上がった履物から選んで購入して履く環境にある。一般ユーザは外出先や服装など、そのシチュエーションやファッションに合わせて履物もコーディネートしたい気持ちがあっても、日常に使う靴などを優先する必要があるし、家庭や家計の事情、保管場所がないなどの理由もあって、鼻緒付き履物を色々なバリエーションでそろえることは諦めざるを得ない。 In particular, it is not a situation where footwear with a umbilical cord and a stand are sold individually to general users, but a footwear store and a favorite lanyard and pedestal can be specified and custom-made. From the finished footwear with a nose, it is in an environment where it can be purchased by selecting from the finished footwear in consideration of appearance and comfort. Even if the general user wants to coordinate their footwear according to the situation and fashion, such as going out and clothing, it is necessary to give priority to shoes used daily, there are no home and household circumstances, storage space etc. For this reason, I have to give up having various kinds of footwear with snares in various variations.
また、靴などは色々な足のサイズに対応しており、シューズの紐や留め具の締め具合で、各自の足の甲の高さや足幅にフィットさせる機能を持つ履物がある。鼻緒付き履物についても鼻緒の長さを調整する先行技術はあるが、人間の足の甲は内側と外側で高さが均等ではないし、左右の足のサイズが違う人もいれば変形している人もいて、鼻緒の一般的な形状からして足の内側と外側に沿う鼻緒長さは均等であるため、ユーザ毎の足の特徴に合わせて鼻緒の長さを前緒と後緒の各々で調整できれば理想的である。 In addition, shoes and so on are compatible with various foot sizes, and there are footwear that has a function to fit the height and width of the foot of each foot by tightening the shoe straps and fasteners. Although there is prior art that adjusts the length of the umbilical cord for footwear with a umbilical cord, the instep of the human foot is not uniform on the inside and outside, and some people have different left and right foot sizes. Because there are people, the length of the umbilical cord along the inside and outside of the foot is uniform because of the general shape of the umbilical cord, so the length of the umbilical cord is adjusted according to the characteristics of the foot for each user. It is ideal if it can be adjusted with.
鼻緒付き履物の台や鼻緒に柔軟性がある例えばビーチサンダルなど、歩行時の負荷で台から鼻緒が不用意に抜けないよう、鼻緒の端は台の穴より約2倍強の大きさで作られており、先行資料の特許文献3のような専門的な挿げ具を用いなければ台に鼻緒を挿げることができない。万一この鼻緒を台から引き抜く力が掛かったときは、台の穴が広がったり亀裂が入り、鼻緒が千切れるなどの損傷が起きて、その鼻緒や台は再び使うことが出来ないのが現状である。
人の手で挿げられる鼻緒として先行資料の特許文献2の履物があるが、複数の分離片を複数回の操作で台の一つの穴に鼻緒の端を入れていくのは複雑で面倒な作業である。鼻緒付き履物には通常3つの穴に鼻緒の3つの端を挿入しなければならず、ユーザにとってわかり易く手間の少ない作業で台に鼻緒を着脱可能とするためには、台に挿げる鼻緒の端の各々が、一つの穴に1回の操作で着脱可能とするのが望ましい。
また、先行資料の特許文献1のように、台の穴に鼻緒の端の各々は1度の操作で挿入できるとしても、台の表側から挿入する鼻緒の端が台の裏側で速やかに固定されるわけではなく、台の穴に挿入した鼻緒の端を台の裏側で固定する作業が必要で、その操作途中で鼻緒の端が台の表側へと抜けだして手間取る可能性がある。
以上のように、一般ユーザが鼻緒付き履物の鼻緒着脱を行うには、まだ色々な課題が残っている。
Footwear with umbilicals and flexibility in umbilicals, such as flip flops, make the end of the umbilical cord about twice as large as the hole in the pedestal so that the umbilical cord will not accidentally come out of the pedestal due to a load during walking. Therefore, it is not possible to insert the cord on the table without using a special insertion tool such as
There is the footwear of
Further, as in the
As described above, various problems still remain for a general user to attach and detach the garment with the umbilical cord.
これらの課題を解決するにあたって、ゴム材やEVA素材など適度に柔軟性がある履物の台に、同じく適度な柔軟性を持つゴム材や樹脂製の鼻緒を挿げてある鼻緒付き履物、主に市販品でいえばビーチサンダルやクッション性のある下駄の場合。
本願の発明では、鼻緒の端をひねって鼻緒付き履物の台に素手のひと押しで挿入できるように、鼻緒の端の鍔を従来の円形から長形にする。台には断面が「凸」の字の形状に見える穴を設け、上の小径が鍔挿入穴で下の大径を鍔固定穴と称して説明すると、鼻緒の端の鍔は端面を長形として側面から見れば「T」の字の形状で成形し、鼻緒を台に挿げるときには、鍔をひねって一時的に「イ」の字の形状に鍔を首部に沿わせて押し込むことで、クッション性のある鍔挿入穴に素手で鼻緒の端を挿入できる。小径の鍔挿入穴を「イ」の字の形状で通り抜けた鼻緒の端は、大径の鍔固定穴に入りきることで鍔は本来の「T」の字の形状に戻り、凸状の大径と小径の段差に鍔が引っかかり鼻緒は容易に台から抜けなくなるので、鼻緒は素手のひと押しで台に挿げて固定ができる。
In solving these problems, rubber footwear and EVA material footwear with moderately flexible footwear, with rubber materials and resinous cords that are also moderately flexible, are mainly used. In the case of commercially available products, beach sandals and cushioned clogs.
In the invention of the present application, the heel of the umbilical cord is changed from a conventional circular shape to an elongated shape so that it can be inserted into a footwear footwear with a umbilical cord by one push of a bare hand. The base is provided with a hole that looks like a “convex” cross section, and the upper small diameter is the 鍔 insertion hole and the lower large diameter is called the 鍔 fixing hole. As seen from the side, when it is molded in the shape of the letter “T” and the cord is inserted into the table, it is necessary to twist the heel and temporarily push the heel into the shape of the letter “I” along the neck. The end of the umbilical cord can be inserted with a bare hand into the cushion insertion hole. The end of the umbilical cord that has passed through the small-diameter hook insertion hole in the shape of the letter “I” returns to the original “T” shape by entering the large-diameter hook fixing hole, and the convex large A ridge is caught in the step between the diameter and the small diameter, and the umbilical cord can not be easily removed from the table, so the umbilical cord can be inserted into the table and fixed with a simple push of the hand.
また、台が木製など硬い材質であり、EVA素材のように一時的に鍔挿入穴が広がるような変化が起きない材質の台の場合は、台の鍔挿入穴の形を鍔と同様の長形とし、ただしその向きは本来の鼻緒を挿げ終えたときより90度回転させた向きで開口し、その鍔挿入穴に連結している鍔固定穴を、本来の鼻緒を挿げ終えた向きで設けておく。
鼻緒を台に挿げるときは、鼻緒の端を本来の向き(挿げ完了時の向き)より90度ひねって鍔挿入穴に入れて、台の裏側に鍔が突出した後に、鼻緒の端を本来の向きに戻して鍔固定穴に鍔を導き設置すれば、鼻緒は素手で台に挿げて固定されることになる。
If the base is made of a hard material such as wood and does not change as the EVA material temporarily expands, the shape of the base insertion hole of the base is the same as that of the base. It has a shape, but its orientation is 90 degrees rotated from the time when the original umbilical cord has been inserted, and the heel fixing hole connected to the heel insertion hole is the direction in which the original nasal cord has been inserted. It is provided with.
When inserting the umbilical cord into the table, twist the end of the umbilical cord 90 degrees from the original direction (the direction when the insertion is completed) and insert it into the heel insertion hole. If you put the bag back in its original orientation and guide the bag into the bag fixing hole, the cord will be fixed by inserting it into the base with your bare hands.
次に鼻緒を台から外すときには、台をEVAなどクッション性のある素材で作り、鼻緒をポリ塩化ビニール(PVC)など外力を加えれば曲がる素材で作っていれば、強引に鼻緒を台から引き抜くように操作することで、EVA素材の鍔挿入穴は一時的に広がり、鼻緒の端の鍔は「ヘ」の字の形状に湾曲して、台から鼻緒を外すことが可能となる。
この強引に抜く力と、履物を使用する時に加わる力とのバランスを予測して、鼻緒の鍔の厚さと大きさ、そして鍔や首の柔軟性および台の鍔挿入穴のサイズを適切に確保して商品を設計しておけば、鼻緒付き履物を使用するときには問題なく、鼻緒を交換するときには人間の素手の力で強引に抜いても、鼻緒や台にダメージは残らず再利用する(再度鼻緒を台に挿げる)ことも可能となる。
Next, when removing the umbilical cord from the pedestal, if the pedestal is made of a cushioning material such as EVA and the ligament is made of a material that bends when applied with an external force such as polyvinyl chloride (PVC), forcibly pull the nasal cord from the pedestal. As a result of the operation, the heel insertion hole of the EVA material temporarily expands, and the heel at the end of the umbilical cord curves into the shape of a “f”, making it possible to remove the nasal cord from the platform.
Predicting the balance between this force to pull out and the force applied when using footwear, ensure the thickness and size of the heel cord, the flexibility of the heel and neck, and the size of the heel insertion hole on the table If the product is designed in this way, there is no problem when using footwear with a snout, and when replacing the snout, even if it is forcibly pulled out with the help of a human hand, it will be reused without any damage to the thong or the base (again It is also possible to insert the cord on the table.
また、台が木製など硬い材質で鼻緒の鍔と同様に長形の鍔挿入穴を設けている場合、鼻緒を台から外すには、鍔固定穴に収まっている鍔を台の裏面に押し出し、意図的に鼻緒の端を90度回転させて、鍔を鍔挿入穴の向きに導くことで簡単に鼻緒を外すことが可能となる。
一般に鼻緒付き履物を履いている時に、鼻緒の向きが本来の向きから勝手に90度回転することはあり得ず、意図的に鼻緒を着脱する動作をしない限り鼻緒は台から外れない。
Also, if the base is made of a hard material such as wooden and has a long heel insertion hole like the chin cord, to remove the umbilical cord from the pedestal, push the heel in the heel fixing hole to the back of the table, By intentionally rotating the end of the nose 90 degrees and guiding the eyelid in the direction of the eyelid insertion hole, it is possible to easily remove the nose.
In general, when wearing footwear with a thong, the direction of the thong cannot rotate 90 degrees from the original direction, and the thong does not come off the stand unless it is intentionally attached or detached.
このように、鼻緒の端の鍔の形状を長形にして、鼻緒付き履物の台の鍔挿入穴および鍔固定穴を鼻緒の鍔が挿入し易いように、固定でき易いように準備することで、本願発明の目的とする素手で鼻緒の着脱と固定が可能となる。
なお、後に説明する実施例1にて鍔挿入穴および鍔固定穴の形状を丸型にしたのは、EVA素材の台の製造加工性が良いためでもあり、EVAのクッション性で鼻緒の着脱が容易なために用いた形状である。
実施例2の長形穴は、EVAのような柔軟性が無い硬い材質の台の場合でも、鼻緒を素手で台に着脱するもう一つの実現手段である。
In this way, the shape of the heel at the end of the umbilical cord is elongated, and the heel insertion hole and the heel fixing hole of the footwear with the umbilical cord are prepared so that it can be easily fixed so that the ridge of the umbilical cord can be easily inserted. The cord can be attached / detached and fixed with the bare hands of the present invention.
In addition, the reason why the shape of the heel insertion hole and the heel fixing hole is rounded in Example 1 described later is also because the manufacturing processability of the EVA material base is good. This is the shape used for ease.
The oblong hole of the second embodiment is another realization means for attaching / detaching the nose to / from the base with bare hands even in the case of a base made of a hard material having no flexibility such as EVA.
さらに本願発明では補強部材を準備する。
鍔固定穴を丸型で設けた場合に長形の鍔がこの空間の中で遊ぶこと、および鼻緒の柔軟性により鼻緒が鍔挿入口より不用意に脱出することを防ぐため、補強部材を用いることで鼻緒は確実に強固に固定される。
補強部材は一般ユーザでも扱い易くするために、鼻緒の端の鍔を容易に囲うことが出来る構造で準備し、鼻緒を台に挿げた後に鼻緒の端に取り付けて鍔固定穴に格納することで、鼻緒の鍔が湾曲することを防ぎ台から安易に抜けることがなくなる。
この補強部材は鼻緒の首部をまたいで差し込む開口部を待ち、鼻緒の鍔の少なくとも三面を囲むことで首部に対して鍔をT字型に固定することができ、鼻緒を台から引き抜く力が掛かっても鍔が湾曲するのを防ぐことで、鼻緒が台から抜けないよう鼻緒の端の固定状態をさらに補強する。
この部材はポリカーボネート(PC)、ポリプロピレン(PP)、ABS樹脂、金属など硬い部材で構成させることで、台や鼻緒の柔軟性による鼻緒の脱出を防ぐための補強になる。
Further, in the present invention, a reinforcing member is prepared.
Use a reinforcing member to prevent the long heel from playing in this space when the heel fixing hole is provided in a round shape, and to prevent the nasal cord from inadvertently escaping from the heel insertion port due to the flexibility of the chin This ensures that the thong is firmly fixed.
In order to make it easier for ordinary users to handle the reinforcing member, it is prepared with a structure that can easily surround the ridge at the end of the umbilical cord, and after being inserted into the base, it is attached to the end of the umbilical cord and stored in the heel fixing hole. This prevents the ridge of the nose from being bent and prevents it from coming out of the base easily.
This reinforcing member waits for an opening to be inserted across the neck of the umbilical cord and surrounds at least three surfaces of the ridge of the umbilical cord, so that the heel can be fixed in a T shape with respect to the neck, and the force for pulling the nasal cord from the base is applied. However, by preventing the beak from bending, it further reinforces the fixed state of the end of the nose so that it does not come off the table.
This member is made of a hard member such as polycarbonate (PC), polypropylene (PP), ABS resin, metal, etc., and serves as a reinforcement for preventing the escape of the cord due to the flexibility of the table and the cord.
また、本願発明では前緒、後緒の各々で鼻緒の長さを調節できる調整部材を準備する。
台に挿げた鼻緒の鍔が鍔固定穴に収まるとき、鍔と台との間に調整部材を差し込むことで、鼻緒付き履物の台の表側に現れる鼻緒(人の足の上に見える部分)の長さを調整可能となる。調整部材は鼻緒付き履物の鼻緒の前尾、右後緒、左後緒それぞれに装着でき、鼻緒の左右を別々の長さに調節することが出来るので、人の足の各々の形に合わせて鼻緒の長さを調整することが可能となる。
なお、この調整部材は上記補強部材の厚さを色々な厚さで提供することでも可能である。
Moreover, in this invention, the adjustment member which can adjust the length of a umbilical cord in each of the beginning and the back is prepared.
When the ridge of the umbilical cord inserted into the pedestal fits in the heel fixing hole, by inserting an adjusting member between the heel and the pedestal, the ridge (the part that can be seen on the person's foot) that appears on the front side of the pedestal footwear The length can be adjusted. Adjustable members can be attached to the front, right back and left back of footwear with foot cords, and the left and right sides of the cord can be adjusted to different lengths, so that it can be adjusted to the shape of each person's foot. It becomes possible to adjust the length of the thong.
The adjusting member can be provided by providing the reinforcing member with various thicknesses.
このように、本願発明では素手で鼻緒を台に着脱して固定できる新たな発想の鼻緒付き履物を提供可能とし、専門の知識がなくても安全な鼻緒固定ができる補強部材と、各自の足の形に合う鼻緒の長さ調整を可能にすることで、従来通り鼻緒付き履物を組立てた状態で販売するのはもちろんのこと、鼻緒だけの販売および、その鼻緒を利用する鼻緒付き履物の台だけなど、個々の販売形態も可能とし、ユーザ自身が好みの色の台にその時の気分やファッションに合わせた鼻緒を挿げて履物を楽しめるよう、新たな鼻緒付き履物とその販売形態を提供可能とするものである。 Thus, in the present invention, it is possible to provide footwear with a new idea that can be attached and detached to and fixed to the base with bare hands, a reinforcing member that can fix the nose safely without specialized knowledge, and each foot By adjusting the length of the umbilical cord that matches the shape of the footwear, the footwear with the umbilical cord can be sold in the assembled state as usual, as well as the sales of the umbilical cord only, and the footwear with the umbilical cord that uses the umbilical cord In addition, it is possible to provide individual sales forms, such as footwear, and users can provide footwear with new nose and its sales form so that users can enjoy footwear by placing a nose tailored to their mood and fashion on the platform of their favorite color It is what.
本発明により履物の台の挿入穴に鼻緒を挿げるには、人間の素手で鼻緒の各端をひねって、ひと押しするだけで鼻緒を台に挿げることが可能となり、鼻緒の鍔が鍔固定穴に収まることで鼻緒が台に固定されるため、台の壺3か所に対して3回の操作を行うだけで、鼻緒を台に挿げると同時に鼻緒を台に固定することができる。このような操作の作業性は先行技術として引用した特許文献1または特許文献2では得られない効果である。
また、この時の鼻緒の鍔の形状は、側面から見れば単にT字型の一体物で鍔を長形状に構成すれば良く、鼻緒の形状が簡単な構造なので製造単価も安く、量産性に優れた鼻緒を提供することが可能となる。
特に台が独立気泡発泡スポンジ(EVA)など硬い材質でありながらクッション性もある素材であり、鼻緒をポリ塩化ビニール(PVC)など適度に柔軟性のある素材で構成されている場合、鼻緒の端を一時的に素手の力でひねることは容易であり、台の挿入穴は押し込む力で多少広がるため、その鼻緒の端を台に準備している鍔挿入穴に通すことは女性の力でも可能である。そして、その鍔挿入穴に連結している鍔固定穴に鍔をはめ込んだら、それだけで鼻緒の端の鍔は本来の形状に戻ることで台に固定される。つまり、鼻緒の端は2本の横緒でがっており、人が履いて歩くためには台の表側(人の足が載る側)に引っ張られることになるので、挿入口側へと鍔が引き戻され、鍔挿入穴に連結している鍔固定穴との段差に鼻緒の鍔が常に引っかかり容易には抜けなくなるので、鼻緒は台に挿げられた状態で固定されることになる。
さらに、本願の実施例1では独立気泡発泡スポンジ(EVA)よりもさらに硬い素材であるポリエスタールまたはABSなどの樹脂や金属などで補強部材を準備し、鼻緒の端の鍔を囲うことにより鍔の変形を防ぎ、鼻緒は鼻緒の端や台の鍔挿入穴や補強部材を破損する力が加わらない限り抜けなくなるので、安心して履物を使用することができる。
According to the present invention, in order to insert the cord into the insertion hole of the footwear table, it is possible to insert the cord into the table by twisting each end of the cord with a human hand and pressing it once. Since the umbilical cord is fixed to the pedestal when it fits in the heel fixing hole, the umbilical cord is fixed to the pedestal at the same time that the umbilical cord is inserted into the pedestal only by performing three operations on the three folds of the pedestal. be able to. Such operational operability is an effect that cannot be obtained in
In addition, the shape of the ridges of the umbilical cord at this time is simply a T-shaped monolithic structure when viewed from the side, and the shape of the umbilical cord is simple, so the manufacturing cost is low and the mass production is easy. It becomes possible to provide an excellent thong.
In particular, if the base is a hard material such as closed cell foam sponge (EVA) but also has cushioning properties, and the nose is made of a moderately flexible material such as polyvinyl chloride (PVC), the end of the nose It is easy to twist with a bare hand temporarily, and the insertion hole of the base expands somewhat with the force of pushing, so it is possible for women to pass the end of the nose through the heel insertion hole prepared in the base It is. Then, when the heel is inserted into the heel fixing hole connected to the heel insertion hole, the heel at the end of the nostril returns to its original shape and is fixed to the base. In other words, the end of the umbilical cord has two sideways, and it is pulled to the front side of the table (the side on which the person's feet rest) in order for a person to wear it and walk. Is pulled back and the hook of the cord is always caught at the step with the hook fixing hole connected to the hook insertion hole, so that it cannot be easily removed, so that the cord is fixed in a state of being inserted into the table.
Further, in Example 1 of the present application, a reinforcing member is prepared with a resin or metal such as polyester or ABS, which is a harder material than closed cell foam sponge (EVA), and by enclosing the heel at the end of the nose Deformation is prevented, and the umbilical cord will not come out unless force is applied to the end of the umbilical cord, the heel insertion hole of the base or the reinforcing member, so that the footwear can be used with confidence.
台から鼻緒を取り外したい場合は、ポリ塩化ビニール(PVC)などの樹脂には適度な柔軟性があるため、強い引っ張り力がかかれば、長形の鍔は「へ」の字型に湾曲して、鍔挿入穴より引き抜くことができる。
本願に記載の補強部材で補強して鼻緒を台に固定している場合には、鼻緒を台の表側から裏側に向けて押し込み、台の鍔固定穴から露出した補強部材を鼻緒の端から外した後、鼻緒を台の表側へと一気に引き抜くことで鼻緒の取り外しが可能である。この場合、台が独立気泡発泡スポンジ(EVA)の場合には、硬い材質ではあるがクッション性もあり、外力が加わると鍔挿入穴が適度に広がるため、女性の一般的な力でも鼻緒を引き抜くことが可能となる。
If you want to remove the thong from the table, the resin such as polyvinyl chloride (PVC) has moderate flexibility, so if a strong pulling force is applied, the long folds will bend into a "he" shape. , Can be pulled out from the hole insertion hole.
When the cord is reinforced with the reinforcing member described in this application and the cord is fixed to the table, push the cord from the front side to the back side of the table, and remove the reinforcing member exposed from the heel fixing hole of the table from the end of the cord. After that, the cord can be removed by pulling the cord to the front side of the table at once. In this case, if the base is an closed cell foam sponge (EVA), it is a hard material, but also has cushioning properties, and when external force is applied, the heel insertion hole is appropriately expanded, so that the woman's general force pulls out the thong It becomes possible.
また、本願の実施例2では木製など、人の力では変形させることが困難な硬さの素材で構成された鼻緒付き履物の台に、本願発明の鼻緒を装着する場合の例を示しているが、鼻緒付き履物の鼻緒本来の向きとは異なる約90度回転した方向で鼻緒を挿入できるように台に長形の鍔挿入穴を設け、台に鼻緒を挿げた後で本来あるべき鼻緒の向きに戻して鍔固定穴に鍔を導くことで台に鼻緒を固定する。
実施例2で鼻緒を台から外す場合には、鼻緒の端を台の裏側へと押し込んで鍔固定穴から鍔を出し、鍔挿入穴の向きに回転(例えば90度の回転)させ鍔挿入穴へと導いて引き出せば鼻緒を台から外すことができるので、人間の素手の力で容易に鼻緒の挿げ替えが可能となる。
Moreover, in Example 2 of the present application, an example is shown in which the umbilical cord of the present invention is mounted on a footwear with a umbilical cord made of a material that is difficult to deform by human power, such as wooden. However, a long heel insertion hole is provided in the base so that the thong can be inserted in a direction rotated about 90 degrees, which is different from the original direction of footwear with a thong. Fix the cord on the table by turning it back and guiding the heel to the heel fixing hole.
When removing the umbilical cord from the table in Example 2, the end of the umbilical cord is pushed into the back side of the pedestal, the heel is taken out from the heel fixing hole, and rotated in the direction of the heel insertion hole (for example, rotated 90 degrees). The cord can be removed from the table by guiding it to the side, so that it can be easily replaced with the power of a human hand.
このように、鼻緒の端の3つの鍔はすべて、鼻緒の端を人の手でひねって挿入し、本来の向きに戻して鍔固定穴に導くことにより鼻緒を台に固定するので、台の挿入穴の3か所に3回の操作で鼻緒の3ヶ所の端を挿入して固定でき、専門知識のないユーザにも簡単に鼻緒の交換が可能になり、意図的に鼻緒を外そうとしない限り通常の使用時には鼻緒は台から外れることは無い。且つ、台や鼻緒の柔軟性を考慮して固定をさらに補強するにも、鼻緒の鍔を台の裏側に押し出した状態で補強部材を鼻緒の端に差し込み、鼻緒を台の表側へ引き上げて、鍔を囲った補強部材を再び鍔固定穴に収めるだけで、鍔の柔軟性による変形を防ぎ、さらに強固に鼻緒が台に固定される。これもまた一般ユーザには非常に扱いやすく、鼻緒を容易に交換できる鼻緒付き履物を提供できる。
鼻緒を台から外すときも、引き抜くだけの簡単操作、または鍔固定穴から鍔挿入穴の向きに鼻緒の端を回転させて引き上げるだけなので、特別なマニュアルがなくても直感的に操作がし易い構造となっている。
In this way, all three ridges at the end of the umbilical cord are inserted by twisting the end of the umbilical cord with a human hand, returning it to its original orientation and guiding it to the heel fixing hole. The three ends of the umbilical cord can be inserted and fixed in three places in the insertion hole three times, making it possible for users without expertise to easily replace the nasal cord, and to intentionally remove the nasal cord. Unless otherwise, the thong will not come off the base during normal use. And in order to further reinforce the fixation considering the flexibility of the table and umbilical cord, the reinforcement member is inserted into the end of the umbilical cord with the ridge of the umbilical cord pushed out to the back side of the table, and the umbilical cord is pulled up to the front side of the table, By simply reinserting the reinforcing member surrounding the heel into the heel fixing hole, deformation due to the flexibility of the heel is prevented, and the cord is firmly fixed to the table. This is also very easy to handle for general users, and can provide footwear with a cord that can easily change the cord.
When removing the umbilical cord from the stand, it can be easily operated simply by pulling it out, or by simply rotating the end of the umbilical cord from the heel fixing hole toward the heel insertion hole and pulling it up. It has a structure.
本願鼻緒の一例としてポリ塩化ビニール(PVC)などの樹脂で鼻緒を準備することは、先に述べたように人の手で鼻緒の端をひねる柔軟性を持ち合わせていることで、本願の目的である素手のひと押しで鼻緒を台に着脱可能な扱いやすさがあると共に、鼻緒そのものが成形品なので多様な色で大量生産が可能であり、尚且つ成型当初とは違う色や新たな柄を、この鼻緒にはプリントすることが可能である。
和風洋風の柄はもちろん、写真や布地のスキャンデータを鼻緒に印刷することも可能なので、例えばビーチサンダルの鼻緒に水着の生地の柄をプリントしてお揃いにすることもできれば、盆踊り大会にチーム名とマークをプリントした鼻緒を挿げた下駄で参加するといったオリジナリティーあふれる鼻緒付き履物を提供することが可能となる。
ユーザの望みに合わせて多彩な色柄を自在にプリントできる鼻緒と、それを挿げて履く台を個別に供給でき、それらを好みや必要に応じて組合せを替えることがユーザの手によって容易に行うことが出来れば、新たな鼻緒付き履物の楽しみな使い方が発生する。
As an example of the present thong, preparing the thong with a resin such as polyvinyl chloride (PVC) has the flexibility to twist the end of the thong with the hand of a human as described above. It is easy to handle with a push of a bare hand and can be attached to and detached from the table, and since the umbilical itself is a molded product, it can be mass-produced in a variety of colors. It is possible to print on this thong.
It is possible to print scan data of photos and fabrics as well as Japanese-style Western patterns, so for example, if you can print the pattern of swimsuit fabric on the sandals of beach sandals, you can team up for the Bon Dance Tournament It is possible to provide footwear with a thong that is full of originality, such as participating in a clog with a name and mark printed on the thong.
A variety of color patterns can be printed according to the user's wishes, and a stand on which to insert them can be supplied individually, and it is easy for the user to change the combination according to their preference and need. If it can be done, a new way to use footwear with nose will be created.
また本願発明には、補強部材の厚みを変えたり調整部材を用いることによって、台の中で鼻緒の端を固定する位置を浅くしたり深くしたり調整可能としている。これによって、鼻緒付き履物の台の表に現れる鼻緒の長さをユーザが簡単に調節できるので、各ユーザの足の甲の高さや足幅、足袋の装着による足の形などに合わせて、鼻緒の長さを自由に調節することで使い勝手が非常に良くなる。
人間の足の甲は内側と外側で高さが均等ではないし、左右の足のサイズが違う人もいれば変形している人もいるが、一般的な鼻緒の形状は足の内側と外側に沿う長さが均等に作られており、ユーザ毎の足の特徴に合わせられないのが常である。本願の履物のように、鼻緒の端を固定する台の3か所の穴の各々で、調整部材を用いることで鼻緒の長さを調節できるようになれば、鼻緒の後緒のそれぞれの長さを個別に調節することが出来るため、片足の内側とその外側で緒の長さを変えて足にフィットさせることが出来る。これは足の変形や特徴に合わせることはもとより、鼻緒の各々の端で長さ調節出来ることで、例えば婦人の足のサイズで21cmから25cmくらいの足サイズがあるとして、2種類くらいの長さの鼻緒を準備するだけで、あとは調整部材によって鼻緒の長さを調節するだけで21cmから25cmの足サイズに対応することが可能となる。
Further, in the present invention, by changing the thickness of the reinforcing member or using the adjusting member, the position where the end of the cord is fixed in the table can be adjusted to be shallower or deeper. This allows the user to easily adjust the length of the umbilical cord that appears on the front of the footwear with lanyard, so that the umbilical cord can be adjusted according to the height and width of the instep of each user, the shape of the foot by wearing a socks, etc. The user-friendliness is greatly improved by freely adjusting the length.
The height of the instep of the human foot is not uniform on the inside and outside, and there are people with different left and right foot sizes, and some people have deformed, but the general shape of the nose is on the inside and outside of the foot In general, the length along the line is made uniform and cannot be matched to the characteristics of the foot for each user. If the length of the umbilical cord can be adjusted by using an adjustment member in each of the three holes of the base that fixes the end of the umbilical cord as in the footwear of the present application, Since the height can be adjusted individually, the length of the cord can be changed on the inside and outside of one foot to fit the foot. This can be adjusted not only according to the deformation and characteristics of the foot, but also by adjusting the length at each end of the nose. For example, there are about 25 to 25 cm foot sizes for women's feet. It is possible to cope with a foot size of 21 cm to 25 cm only by preparing the umbilical cord and adjusting the length of the umbilical cord with the adjusting member.
本願発明は、鼻緒付き履物の鼻緒に特徴があり、それに対応する形で鼻緒付き履物の台が準備されることで、商品の販売方法としては、従来通りのセットされた鼻緒付き履物としての販売はもちろんのこと、鼻緒を自由に交換可能な鼻緒付き履物として、台単体の販売や鼻緒だけの販売も可能となる。
これにより、ユーザは一つの台を持っているに過ぎなくても、鼻緒の交換により多数の雰囲気の履物を持っているに等しくなり、台の色や形が違うものを持っていれば、複数の台と複数の鼻緒の組合せにより、数倍の雰囲気が違う鼻緒付き履物を好みで使い分けることが可能となる。
台と鼻緒を個別に提供できるようになることは、多彩な色や模様や形の鼻緒、および色々な色柄や形の台を購入して組み合わせることにより、ユーザは自由に自分好みの組合せで履物をセッティングすることができ、服装のタイプや色柄そして外出先など、その時々のシチュエーションに合わせて履物を自由にカスタマイズする楽しみがある。素手で鼻緒が交換できるということは、例えば昼は洋装でカラフルな鼻緒を挿げた履物を、夜にはシックな鼻緒に交換して和装に合わせるなど、外出先に鼻緒を数本持参して交換することにより、その状況に合う履物の台と鼻緒の組合せにユーザの手で交換することで、一つの履物の台で複数の履物バリエーションを演出することができる。
特に鼻緒付き履物としては、代表的な下駄から草履、雪駄、サンダルなど色々な履物があり、これら色々なジャンルの台に対して、ジャンルを超えて共通の鼻緒を使うことも可能であり、本発明によってユーザ側で鼻緒が簡単に挿げ替えられる新感覚の鼻緒付き履物を提供することが可能となる。
The invention of the present application is characterized by the umbilical cord of the footwear with a umbilical cord, and the footwear with the knitted footwear is prepared in a corresponding form. Needless to say, it is possible to sell the stand alone or sell only the thong as footwear with a thong that allows the thong to be freely exchanged.
This means that even if the user has only one stand, it is equivalent to having a large number of footwear by exchanging thongs, and if the stand has a different color or shape, The combination of the base and multiple umbilical cords makes it possible to properly use footwear with umbilical cords that have a different atmosphere several times.
Being able to provide the platform and cord separately, users can freely combine the platform of various colors, patterns and shapes, and various color patterns and shapes, and users can freely combine them with their own preference. You can set footwear, and there is a pleasure to freely customize the footwear according to the occasional situation, such as the type of clothing, color pattern and whereabouts. The ability to change the cord with bare hands means that, for example, you can exchange footwear with a colorful chord with Western clothing in the daytime, exchange it with a chic chord at night and bring it to the kimono, etc. Thus, a plurality of footwear variations can be produced on a single footwear base by exchanging the footwear base and thong suitable for the situation by a user's hand.
In particular, there are various footwear with thongs, from typical clogs to sandals, snow sands, sandals, etc., and it is possible to use common thongs across genres for these various genre bases. According to the present invention, it is possible to provide footwear with a new sense that can be easily replaced on the user side.
鼻緒の端の鍔を従来の丸型ではなく長形にし、各端をひねって、台の鍔挿入穴に入れる鼻緒の端のサイズを一時的に小さくすることで、人間の素手のひと押しで鼻緒を台に挿げることを可能とし、素手の引き抜く力で鍔が湾曲して鼻緒を台から外すことが出来る鼻緒とそれを挿げる台。
その鼻緒の柔軟性を補って台に鼻緒を確実に固定するための補強部材を持ち、さらに台の表で足の上に現れる鼻緒の長さを調節することが出来る調整部材を持つことで、鼻緒と台の組合せを容易に交換可能でありながら鼻緒を確実に台に固定し、尚且つ鼻緒の長さ調整も可能とした実施例1の形態。
および、鍔と同様に長形の鍔挿入穴を設けた台に、鼻緒の端をひねって鍔挿入穴に合わせて鍔を入れ、その穴に連結し角度を変えて設けた鍔固定穴に鼻緒の鍔を導くことで鼻緒を台に挿げ、鼻緒を台から外すときは鍔固定穴から鍔を出して鼻緒の端を回転させ、鍔挿入穴に導くことで鼻緒を台から外せる実施例2の形態。
これら鼻緒と台の組合せを容易に変更できるように、人間の素手の力で鼻緒を台に挿入抜出できるとともに、柔軟性のある鼻緒や台を確実に固定する補強部材、および鼻緒の長さを変更する調整部材を有する鼻緒および鼻緒付き履物を提案する。
By making the ridges of the umbilical end longer than the conventional round shape, twisting each end and temporarily reducing the size of the ridge of the umbilical cord to be inserted into the heel insertion hole of the platform A cord that can be inserted into the table, and that can be removed from the table by bending the heel with the pulling force of a bare hand and a table on which it can be inserted.
By having a reinforcing member to fix the umbilical cord securely to the table to compensate for the flexibility of the umbilical cord, and further having an adjusting member that can adjust the length of the umbilical cord that appears on the foot on the table surface, The embodiment of the first embodiment in which the combination of the umbilical cord and the table can be easily exchanged while the umbilical cord is securely fixed to the table and the length of the umbilical cord can be adjusted.
And, like the heel, twist the end of the nostril on the base with the long heel insertion hole, put the heel along the heel insertion hole, connect it to the hole and change the angle to the heel fixing hole. Example 2 where the umbilical cord can be inserted into the table by guiding the heel, and when removing the umbilical cord from the pedestal, the ridge is removed from the heel fixing hole, the end of the umbilical cord is rotated, and the umbilical cord can be removed from the table by guiding it to the heel insertion hole. Form.
In order to easily change the combination of these cords and platforms, the cords can be inserted into and removed from the platform with the help of human hands, and the flexible cords and the reinforcing members that securely fix the platform, and the length of the cords The present invention proposes footwear with a thong and thong having an adjustment member for changing the shape.
本願の鼻緒を挿げる対象物として、2種類の鼻緒付き履物の台の構造を本願発明の説明では行っている。
実施例1の発明は鼻緒付き履物の台を独立気泡発泡スポンジ(EVA発泡)のように、ある程度硬いがクッション性も保持している素材で、外力が加われば局部的に多少の変形が可能な柔軟性があり、力を加えなければ復元性のある部材を使った場合の実施例である。
また実施例2の発明は、鼻緒付き履物の台を木製などさらに硬質な部材で製作したときの実施例である。
なお、実施例1も実施例2も一つの事例として説明しているが、各々の部材は実施例に記載した部材の特性に本願鼻緒の構造上の特徴が生かされ、同じ効果が生まれるものであれば、実施例に記載の部材に限定されるものでは無い。
In the description of the present invention, two types of footwear-attached footwear structures are used as objects to which the cord of the present application can be inserted.
The invention of Example 1 is a material that is hard to some extent but has cushioning properties, such as closed cell foam sponge (EVA foam), and can be slightly deformed locally when external force is applied. This is an embodiment in the case of using a member that is flexible and can be restored if no force is applied.
The invention of the second embodiment is an embodiment when the footwear with nose is made of a harder member such as wooden.
In addition, although Example 1 and Example 2 are described as one example, each member utilizes the structural characteristics of the present application in the characteristics of the member described in the example, and the same effect is produced. If there is, it is not limited to the members described in the embodiments.
図1は本願発明の鼻緒を説明した図である。
図1にて鼻緒(2)は足の親指と人差し指の間に挟み込む前緒(21)と左右2本の横緒(22)とその先に左右の後緒(23)が設けられ、本願発明の鼻緒(2)はこの前緒(21)と後緒(23)の端に、T字型の一体物で設けられる鍔(24)の端面形状を長形にすることで、鼻緒の端の各鍔を人の素手でひねって台に挿入可能にして鼻緒を台に固定するものである。
ここでいう鍔の端面形状が長形とは、鼻緒(2)の3か所の首部(25)の先に側面から見たら「T」の字の形状に鍔(24)が一体物で成型されており、「T」の字で例えるなら上の面、図1でいえば下から見た鼻緒の末端部分の面の形状が長形である。
この鍔は従来品の鼻緒(ビーチサンダルなど)では丸型で作られているものが多く、挿げ具などの冶具で一気に台の小さな穴に挿げて固定するものである。小さな穴を通過した鍔は歩行時にも抜けない安全性があるが、挿げ具などの冶具を使わず人の素手で鼻緒を台に挿げることはできない。本願の鍔(24)の詳細については、後の図3の説明および実施例1の最後にさらに詳しく説明する。
ちなみに、本願の鼻緒(2)はポリ塩化ビニール(PVC)などで作られ、その柔軟性から前緒(21)の端や、後緒(23)の端を人の素手でひねることが出来る部材で製作をしているが、鼻緒の端を素手の力でひねることができ、且つ外力が加わらない場合は鍔が元の形状に自然に復元する部材であれば、鼻緒の端の部材は何でも良い。
本願発明はこの鼻緒の端の鍔(24)によって、後の図2で述べる鼻緒付き履物の台の鍔挿入穴に、鼻緒の端の各鍔を人の素手でひねって台に挿入して、台に固定可能とする鼻緒の発明であり、この鼻緒を挿げた鼻緒付き履物、またはこの鼻緒付き履物の台である。
余談ではあるが、ポリ塩化ビニール(PVC)で製作した鼻緒は、鼻緒そのものが成形品なので多様な色で大量生産が可能であり、尚且つ成型当初とは違う色や新たな柄をプリントすることが可能で、ユーザの好みに合ったデザインで多彩な色柄のプリントを施した鼻緒を提供することができる。
専門の鼻緒挿げ具や冶具を使うことなく素手で鼻緒を挿げて固定が出来るようになれば、一人のユーザが一つの鼻緒付き履物に対していろいろなデザインの鼻緒を複数持ち、そのときの気分やファッションコーディネートなど鼻緒付き履物を履くシチュエーションに合わせて、都度ユーザが自分の手で鼻緒を簡単に交換し、一つの鼻緒付き履物を複数の異なるイメージの履物として楽しむことが可能となる。
FIG. 1 is a diagram for explaining the thong of the present invention.
In FIG. 1, the umbilical cord (2) is provided with a forehead (21) sandwiched between the thumb and forefinger, two left and right side crossings (22), and a left and right backside (23) ahead thereof. The umbilical cord (2) is formed at the end of the anterior (21) and posterior (23) by making the shape of the end surface of the heel (24) provided as a T-shaped monolith into an elongated shape. Each ridge is twisted with a person's bare hand so that it can be inserted into the table, and the thong is fixed to the table.
Here, the shape of the end face of the heel is long. When viewed from the side of the neck (25) of the three chin cords (2), the heel (24) is molded into a single “T” shape. For example, the shape of the upper surface if it is represented by the letter “T”, and the shape of the surface of the end portion of the nose as viewed from the bottom in FIG.
Many of these ridges are made in a round shape with conventional swords (beach sandals, etc.), and they are fixed by inserting them into small holes on the table at once with a jig such as an insertion tool. A shark that has passed through a small hole is safe even when walking, but it cannot be inserted into the table with a human hand without using a tool such as a tool. Details of the bag (24) of the present application will be described in more detail later in the description of FIG. 3 and the end of the first embodiment.
By the way, the umbilical cord (2) of this application is made of polyvinyl chloride (PVC), etc., and because of its flexibility, the end of the forehead (21) and the end of the back (23) can be twisted with human hands. However, as long as the edge of the umbilical cord can be twisted with bare hands and no external force is applied, the ridge is naturally restored to its original shape. good.
According to the present invention, the ridges (24) at the end of the umbilical cord are inserted into the heel insertion holes of the footwear with the umbilical cord described later in FIG. It is an invention of a umbilical cord that can be fixed to a table, and is a footwear with a umbilical cord in which the umbilical cord is inserted, or a footwear platform with this umbilical cord.
As an aside, the thong made of polyvinyl chloride (PVC) can be mass-produced in a variety of colors because the thong is itself a molded product, and it is also possible to print different colors and new patterns from the beginning. It is possible to provide a thong with a variety of color prints with a design that suits the user's preference.
If you can insert and fix the umbilical cord with your bare hands without using a specialized umbilical cord insertion tool or jig, a single user will have multiple lanyards of various designs for one piece of laced footwear. In accordance with the situation of wearing footwear with nose, such as mood and fashion coordinates, users can easily exchange the snout with their own hands each time and enjoy one footwear with a nose as different footwear.
鼻緒付き履物というと下駄やビーチサンダルが一般的であり、本願では下駄の台をイメージした図で説明している。これらの履物は購入時にセットされている鼻緒と台の組合せで履き続けるのが一般的であり、傷んだり飽きたりサイズが合わなくなって履けないなどの理由で次の履物を入手するが、購入当初には良いと思った履物の色柄がどんな色柄の服装にも似合うわけではなく、人によっては複数の履物を購入したり、1足で我慢して履き続ける人はファッションコーディネートの要素を履物には求めなくなっている場合が多々ある。
本願はこれら下駄やビーチサンダルなどの鼻緒を、素手でいつでも交換できるようにすることで、例えば週末に出かけた海水浴場では、水着とおそろいの色柄をプリントした鼻緒を挿げた履物で海岸を歩き、その夜の花火大会には浴衣姿に着替えて、和風柄の鼻緒に挿げ替えた履物で花火を見る、といった使い方を可能にするものである。このように一人で一つの台と複数の鼻緒を持つことで、服装やその時の気分で鼻緒を変更して、いろいろな印象の鼻緒付き履物をシチュエーションに合わせて使うのも楽しみなことであり、もしも形や色が違う台を持っていれば、鼻緒と台の色柄の組合せは数倍に膨らむ。また例えば家族で、または友人と同種の履物を購入する場合には、複数の鼻緒を交換したり貸しあったりすることで鼻緒と台の色柄の組合せは何倍にも増えて、気分やシチュエーションに合わせて服装とコーディネートする楽しみとともに、共通の履物をいかに恰好よく組合せているか見せあったり、ファッションコーディネートやバリエーションアイデアの話題に盛り上がるなど、コミュニケーションの活性化にもなり得るものである。
Clogs and flip flops are common for footwear with snouts, and in the present application, they are explained with the image of clogs. It is common to keep wearing these footwear with the combination of the thong and the base set at the time of purchase, and the next footwear is obtained for reasons such as being damaged, getting tired, or unable to wear because the size does not fit, but at the time of purchase The color pattern of footwear that I thought was good for the clothes doesn't look good with any color pattern, and some people buy more than one footwear, and those who continue to wear with one foot wear the elements of fashion coordination There are many cases that are no longer required.
This application makes it possible to replace these clogs such as clogs and flip flops with bare hands at any time.For example, at a beach where you went out on the weekend, walk along the beach with a swimsuit and footwear with a matching color printed on the matching color pattern. In the evening fireworks display, you can change to a yukata and see the fireworks in footwear with a Japanese pattern. In this way, by having one table and multiple thongs alone, it is fun to change the thong with clothes and mood at that time, and use footwear with various thongs according to the situation, If you have a table with a different shape and color, the combination of the thong and the color of the table will swell several times. Also, for example, when purchasing footwear of the same kind as a family or a friend, the combination of the umbilical cord and the pedestal can be increased several times by exchanging or lending multiple umbilical cords. In addition to the pleasure of coordinating with clothes according to the situation, it is possible to show how well the common footwear is combined, and the topic of fashion coordination and variation ideas can be activated, which can also stimulate communication.
図2は実施例1の鼻緒付き履物(1)の斜視図である。
図2に示すように、実施例1の鼻緒付き履物(1)は図1の鼻緒(2)を着脱するための台(3)と、必要に応じて用いられる補強部材(4)で構成されることを図で示している。
鼻緒付き履物(1)の台(3)には、鼻緒(2)の前緒(21)と2つの後緒(23)を挿げるための、断面が「凸」の字に見える形状で大小の連なる丸穴が設けられており、小径の穴は鼻緒(2)の端の鍔(24)を挿入するための鍔挿入穴(33)であり、その下の大径の穴は鼻緒(2)の端の鍔(24)を格納して固定する鍔固定穴(34)である。
本発明では鼻緒をポリ塩化ビニール(PVC)で製作し、台は独立気泡発泡スポンジ(EVA発泡)で作っている。
図2ではさらに独立気泡発泡スポンジ(EVA発泡)より硬い材質であるポリカーボネイト(PC)、ポリプロピレン(PP)、ABS樹脂や金属などで作られた補強部材(4)を用いて、鼻緒(2)の3か所の鍔(24)を台(3)の3か所の鍔固定穴(34)でさらに固定する関係を図示している。なお、補強部材(4)は補強部材本体(41)と補強部材蓋(42)で構成されるが、詳細は図5および図6にて説明する。
FIG. 2 is a perspective view of the footwear (1) with a nose according to the first embodiment.
As shown in FIG. 2, the footwear (1) with the nose of Example 1 is composed of a base (3) for attaching / detaching the nose (2) of FIG. 1 and a reinforcing member (4) used as necessary. This is shown in the figure.
On the base (3) of the footwear (1) with umbilical cord, the cross section can be seen as a “convex” character to insert the umbilical cord (2) forehead (21) and two posterior (23). A large and small round hole is provided, and the small diameter hole is a heel insertion hole (33) for inserting the heel (24) at the end of the umbilical cord (2). It is a hook fixing hole (34) for storing and fixing the hook (24) at the end of 2).
In the present invention, the cord is made of polyvinyl chloride (PVC) and the base is made of closed cell foam sponge (EVA foam).
In FIG. 2, a reinforcing member (4) made of polycarbonate (PC), polypropylene (PP), ABS resin or metal which is harder than closed-cell foamed sponge (EVA foam) is used. The relationship of further fixing the three hooks (24) with the three hook fixing holes (34) of the base (3) is shown. The reinforcing member (4) includes a reinforcing member main body (41) and a reinforcing member lid (42). Details will be described with reference to FIGS.
図3は、図2の鼻緒(2)の端の鍔(24)を台(3)に挿げるときの説明と、鼻緒(2)の端の鍔(24)を台(3)から抜き出すときの説明を示したものである、
図中の(3−1)は、鼻緒(2)の端に「T」字型で連なる端面が長形の鍔(24)を縦にひねって首部(25)に沿わせ、台(3)の鍔挿入穴(33)に挿入するときの様子を示した図である。
本発明の鼻緒(2)はポリ塩化ビニール(PVC)など柔らかい樹脂を成形して製作しており、鼻緒(2)の端の鍔(24)を図のように折り曲げることが可能である。これによって、鼻緒(2)の端は縦長形状に一時的に変形させることができ、人の素手の力で容易に台(3)の鍔挿入穴(33)に鍔(24)を挿入することが可能となる。そして、一旦挿入が出来た鍔(24)は、台の鍔挿入穴(33)に連なって設けられた鍔固定穴(34)の中で、元の「T」字型の形状に戻って鼻緒(2)を台(3)に固定することが可能となる。
従来のビーチサンダルなど鼻緒付き履物の鼻緒は、本願でいう鍔(24)の端面形状が円形のものがほとんどであり、専用の鼻緒挿げ具などの治具を用いて強力な力で小さな穴に鍔を一気に通すことで鼻緒を台に挿げている。円形の鍔は、小さな穴(本願でいう鍔挿入穴)を容易には通らないため鼻緒が抜けにくい鼻緒付き履物に仕上がっている。この従来通りの円形の鍔であれば、本願の鼻緒のように例えポリ塩化ビニール(PVC)など柔らかい樹脂で成形して鍔を一時的にひねったとしても、丸い鍔はどの方向にひねっても同一の直径があるため本願のように鍔挿入口に対して鼻緒の端を一時的に細長くすることはあり得ない。
本願の鍔(24)は長形に準備することで、長手方向は鍔が抜けにくい従来品の鍔の直径サイズを確保し、短い方向で鍔が穴に通りやすい状況を確保することにより、鼻緒(2)の端の鍔(24)を(3−1)のように縦長方向にひねって首部(25)に沿わせて一時的に鼻緒(2)の端を細くすることで、鍔挿入穴(33)に挿入し易くすることが可能である。また、後で述べる(3−2)のように鼻緒(2)を台(3)から引き抜く折にも、本願の鍔(24)のように一時的に「ヘ」の字型に変形させることは、従来品の円形の鍔には得られない状況であり、鍔(24)を長形にすることで鼻緒(2)を台(3)に対して、素手で挿入可能および素手の力で引き抜くことが実現可能となる。
なお、ここでは鼻緒(2)の端から鍔(24)の材質をポリ塩化ビニール(PVC)で説明をしているが、鼻緒(2)の端をひねるなどの変形をさせて鍔(24)を台(3)の鍔挿入穴(33)に挿げて、その後自然に元の形状に戻る部材であれば鼻緒(2)の端から鍔(24)の部材は他の部材でも何ら問題は無い。
FIG. 3 illustrates the case where the ridge (24) at the end of the umbilical cord (2) in FIG. 2 is inserted into the table (3), and the ridge (24) at the end of the umbilical cord (2) is extracted from the table (3). Is an explanation of when
In the figure, (3-1) indicates that the end of the umbilical cord (2) is a "T" -shaped end face, and a long heel (24) is twisted vertically along the neck (25) to bring the base (3) It is the figure which showed the mode at the time of inserting in the scissors insertion hole (33).
The cord (2) of the present invention is manufactured by molding a soft resin such as polyvinyl chloride (PVC), and the ridge (24) at the end of the cord (2) can be bent as shown. As a result, the end of the umbilical cord (2) can be temporarily deformed into a vertically long shape, and the heel (24) can be easily inserted into the heel insertion hole (33) of the table (3) with the help of a human hand. Is possible. The cage (24) once inserted is returned to the original “T” shape in the cage fixing hole (34) provided continuously to the cage insertion hole (33) of the base. (2) can be fixed to the base (3).
Conventional foot sandals such as flip flops have a circular shape on the end face of the heel (24) in the present application, and a small hole with a strong force using a jig such as a dedicated umbilical cord insertion tool. The cord is put on the table by passing the candy in a stroke. The circular heel is finished into footwear with a chin that does not easily pass through a small hole (the heel insertion hole referred to in the present application) because it does not easily pass through. With this conventional circular fold, even if the heel is temporarily twisted by molding with a soft resin such as polyvinyl chloride (PVC) as in the case of the present application, the round fold can be twisted in any direction. Because of the same diameter, it is impossible to temporarily elongate the end of the umbilical cord with respect to the heel insertion opening as in the present application.
By preparing the bag (24) of the present application in a long shape, the diameter of the conventional bag is difficult to remove in the longitudinal direction, and the situation in which the bag can easily pass through the hole in the short direction is ensured. Twist the heel (24) at the end of (2) in the longitudinal direction as shown in (3-1) and temporarily narrow the end of the umbilical cord (2) along the neck (25), It is possible to facilitate insertion into (33). Also, as described later in (3-2), even when the cord (2) is pulled out of the base (3), it is temporarily deformed into a “f” shape like the bag (24) of the present application. Is a situation that cannot be obtained with the conventional round heel, and by making the heel (24) long, the umbilical cord (2) can be inserted into the base (3) with bare hands and with bare hands Pulling out becomes feasible.
Here, the material of the heel (24) is described with polyvinyl chloride (PVC) from the end of the umbilical cord (2), but the ridge (24) is deformed by twisting the end of the umbilical cord (2). Can be inserted into the heel insertion hole (33) of the pedestal (3) and then returned to its original shape. No.
図3の(3−2)は、挿げられた鼻緒(2)の鍔(24)を台(3)から引き抜く場合の様子を示した図である。
鼻緒(2)の鍔(24)の部材はポリ塩化ビニール(PVC)で製作され、台(3)は独立気泡発泡スポンジ(EVA)のように、ある程度硬い部材だがクッション性も保持しており、局部的には指で押せば適度に穴が広がる柔軟性のある部材で構成されているため、一般的な人の力でも鍔固定穴(34)から鍔挿入穴(33)に向けて鼻緒(2)を引っ張ることで、鍔(24)を一時的に「ヘ」の字型に変形させることが可能であり、台(3)の鍔挿入穴(33)も一時的に鍔の引き抜き力で横に押されて穴が広がり、鍔挿入穴(33)から鍔(24)を素手の力で引き抜くことが可能となる。
つまり、台(3)の鍔挿入穴(33)の径(台のクッション性による穴の広がり径も鑑み)を、鍔(24)が「ヘ」の字型に変形した時の大きさが通過できるサイズにし、鼻緒(2)の鍔(24)の部材選びと台(3)の部材選びが適切であって、台(3)の鍔挿入穴(33)の径と、鼻緒(2)の鍔(24)の寸法を決定することにより、鼻緒(2)を台(3)から素手で引き抜くことが出来る。
例えば、台(3)の鍔挿入穴(33)の径を(L1)とし、鼻緒を抜くときに鍔挿入穴が台(3)の部材の柔らかさにより(+α)広がるとしたとき、鼻緒を抜くときの鍔挿入穴(33)の径は一時的に(L1+α)ということになる。鼻緒(2)の鍔(24)についても、人の素手で鼻緒を引き抜くとき、鍔が「ヘ」の字型に変形して鍔挿入穴(33)を通るときに、この鍔(24)の対角寸法が(L1+α)になることで、鼻緒(2)の鍔(24)を台(3)から引き抜くことが可能となる。
実施例1では、ポリ塩化ビニール(PVC)で鼻緒全体を成形して製作し、台(3)は独立気泡発泡スポンジ(EVA)に鍔挿入穴(33)を開けてこれを実現している。なお、鍔固定穴(34)の径は、長形の鍔(24)が「ヘ」の字型に変形しない本来の状態の対角線の長さより大きな径とし、図2の台(3)の前壺(31)および後壺(32)を構成している。
(3-2) of FIG. 3 is a diagram showing a state in which the ridge (24) of the inserted cord (2) is pulled out from the table (3).
The member of the ridge (24) of the cord (2) is made of polyvinyl chloride (PVC), and the base (3) is a somewhat hard member like the closed cell foam sponge (EVA), but also retains cushioning properties, Locally, it is made of a flexible member that expands the hole moderately when pressed with a finger. Therefore, even with general human power, the cord (34) from the heel fixing hole (34) toward the heel insertion hole (33) By pulling 2), it is possible to temporarily deform the heel (24) into a “f” shape, and the heel insertion hole (33) of the base (3) can also be temporarily removed by the pulling force of the heel. The hole is widened by being pushed to the side, and the heel (24) can be pulled out from the heel insertion hole (33) with the force of a bare hand.
In other words, the diameter of the heel insertion hole (33) of the pedestal (3) (in consideration of the diameter of the hole due to the cushioning property of the pedestal) passes through the size when the ridge (24) is deformed into a "F" shape. Select the size of the ridge (24) of the chin cord (2) and the selection of the pedestal (3), and the diameter of the heel insertion hole (33) of the pedestal (3) By determining the dimensions of the heel (24), the umbilical cord (2) can be pulled out of the table (3) with bare hands.
For example, if the diameter of the heel insertion hole (33) of the base (3) is (L1) and the heel insertion hole widens (+ α) due to the softness of the member of the base (3), The diameter of the eaves insertion hole (33) when removing is temporarily (L1 + α). As for the ridge (24) of the umbilical cord (2), when the ridge is pulled out with the bare hand of the person, when the heel is deformed into a “f” shape and passes through the heel insertion hole (33), By setting the diagonal dimension to (L1 + α), it is possible to pull out the ridge (24) of the cord (2) from the table (3).
In Example 1, the entire cord is formed by molding with polyvinyl chloride (PVC), and the base (3) realizes this by opening the heel insertion hole (33) in the closed cell foam sponge (EVA). The diameter of the eaves fixing hole (34) is larger than the length of the diagonal line in the original state in which the elongate eaves (24) are not deformed into a “f” shape, and the front of the base (3) in FIG. The kite (31) and the rear kite (32) are constituted.
ここまでの説明で、鼻緒(2)が台(3)に一般的な人の力で挿げたり外したり出来る様子を説明したが、歩行時の負荷などで挿げた鼻緒(2)が台(3)から不用意に外れなくするために、さらに固定を補強しておくのが好ましい。このために図2で説明した補強部材(4)を用いて鼻緒(2)が台(3)に挿げられた後、補強部材(4)で鼻緒(2)の鍔(24)を台(3)の鍔固定穴(34)の中で確実に固定する工夫が求められる。そのための補強部材(4)を用意するとともに、台(3)の表側に現れる鼻緒(2)の長さをユーザの足の形やサイズに合わせて調節可能とする調整部材を提案する。
図4は補強部材(4)を台(3)の鍔固定穴(34)の中で使用する鼻緒付き履物(1)を裏から見た斜視図であり、図5はこの補強部材(4)の使い方を説明した図、およびさらに鼻緒(2)の長さを調整する調整部材(5)を説明した図である。
In the above description, we have explained how the umbilical cord (2) can be inserted into and removed from the platform (3) with general human power. It is preferable to further reinforce the fixing so as not to accidentally disengage from 3). For this purpose, after the umbilical cord (2) is inserted into the platform (3) using the reinforcing member (4) described in FIG. 2, the ridge (24) of the umbilical cord (2) is mounted on the platform (3) with the reinforcing member (4). There is a need for a device to securely fix the rod in the rod fixing hole (34) of 3). For this purpose, a reinforcing member (4) is prepared, and an adjusting member is proposed that can adjust the length of the chord (2) appearing on the front side of the table (3) according to the shape and size of the user's foot.
FIG. 4 is a perspective view of the footwear (1) with a nose using the reinforcing member (4) in the heel fixing hole (34) of the base (3), and FIG. 5 is a perspective view of the reinforcing member (4). It is the figure explaining how to use, and the figure explaining the adjustment member (5) which adjusts the length of a chord (2) further.
なお実施例1での補強部材(4)は、台(3)の部材である独立気泡発泡スポンジ(EVA)より硬いポリカーボネート(PC)、ポリプロピレン(PP)、ABS樹脂や金属などの部材で製作することにより、台(3)に挿げた後の鼻緒(2)の端の鍔(24)を確実に固定し、鼻緒が台(3)から不用意に外れないように補強して固定することを目的とする。
ここでいう補強して固定とは、台(3)の鍔固定穴(34)の中で鼻緒(2)の端の鍔(24)が大きく遊離しないように補強することを意味している。(3−2)で説明したように、鼻緒(2)が引っ張られることにより鍔(24)が「ヘ」の字型に変形することで鍔挿入穴(33)から鍔(24)を引き抜くことができるが、補強部材(4)は後に述べるように、鍔(24)が「ヘ」の字型に変形するのを防ぐことで、台(3)から鼻緒(2)が離脱できないよう補強して固定をするものである。
また、実施例1の調整部材(5)は合成ゴム、天然ゴム、金属などの硬い固形物であって、所定の厚みを持つ部材を加工して作られたものであり、鼻緒(2)の端の鍔(24)を台(3)の鍔固定穴(34)の中でどれだけ沈めて固定させるか、鍔(24)を固定する深さ位置を調整する目的の部材である。
補足として、実施例1の補強部材(4)、調整部材(5)は前記した部材で製作しているが、補強部材の目的として台(3)の鍔固定穴(34)で鍔(24)を補強して固定できるもの、調整部材の目的として鼻緒(2)の端の鍔(24)を台の鍔固定穴(34)の中で位置調整が行える部材であれば、上記で説明している各部材の名称には拘らない。
The reinforcing member (4) in Example 1 is made of a member such as polycarbonate (PC), polypropylene (PP), ABS resin or metal which is harder than the closed cell foam sponge (EVA) which is a member of the base (3). The ridge (24) at the end of the umbilical cord (2) after being inserted into the pedestal (3) is securely fixed, and reinforced and fixed so that the lanyard is not inadvertently detached from the pedestal (3). Objective.
Reinforcement and fixation here means to reinforce so that the heel (24) at the end of the umbilical cord (2) is not largely separated in the heel fixing hole (34) of the base (3). As described in (3-2), pulling out the collar (24) from the collar insertion hole (33) by deforming the collar (24) into the shape of "f" by pulling the cord (2). However, as will be described later, the reinforcing member (4) is reinforced so that the cord (2) cannot be detached from the base (3) by preventing the collar (24) from being deformed into a “f” shape. To fix.
The adjustment member (5) of Example 1 is a hard solid material such as synthetic rubber, natural rubber, metal, etc., and is made by processing a member having a predetermined thickness. This is a member for adjusting the depth position for fixing the flange (24), how much the end flange (24) is submerged and fixed in the anchor fixing hole (34) of the base (3).
As a supplement, the reinforcing member (4) and the adjusting member (5) of Example 1 are made of the above-described members. However, for the purpose of the reinforcing member, the hooks (24) are formed in the hook fixing holes (34) of the base (3). If it is a member that can adjust the position of the collar (2) at the end of the cord (2) as an adjustment member within the collar fixing hole (34) of the base, it can be described above. Regardless of the name of each member.
図4は実施例1の鼻緒付き履物(1)を裏から見た図であって、台の前壺(31)に挿入された鼻緒(2)の鍔(24)を補強部材(4)に組み込んだ図を示している。また右奥の後壺(32)では、既に鼻緒(2)の鍔(24)を補強部材(4)に装着し補強部材蓋(42)が見えている後壺(32)の状態を図示し、右手前の後壺(32)では、まだ鼻緒(2)を挿げてなく補強部材も装填されていない状態の後壺(32)を図示している。
もう少し詳しく説明すると、図4の台の前壺(31)の鍔固定穴(34)に挿げられている鼻緒(2)の鍔(24)は、補強部材(4)の補強部材本体(41)の鍔挿入口(46)から差し込まれ、その鍔挿入口(46)の空間が鼻緒(2)の首部(25)を跨ぐ形で鍔設置部(47)に鍔(24)が配置される。そして補強部材蓋(42)で上から覆うことで、鼻緒(2)の端が本来あるべき「T」字型になるよう鍔(24)が囲われた状態で、鍔固定穴(34)の中に補強部材(4)を収納している。
図4の右奥の後壺(32)は、この補強部材(4)の中に鼻緒(2)の鍔(24)を収納して、補強部材本体(41)を補強部材蓋(42)で覆い、鍔固定穴(34)の中に補強部材(4)を収納し終わった状態を図示している。また右手前の後壺(32)は、まだ鼻緒(2)の鍔(24)を挿げる前の状態で、後壺(32)の鍔固定穴(34)が台の裏から見えている状態を示している。
FIG. 4 is a view of the footwear (1) with the umbilical cord of Example 1 as viewed from the back, and the heel (24) of the umbilical cord (2) inserted into the front heel (31) of the table is used as the reinforcing member (4). The incorporated figure is shown. Also, in the rear right heel (32), the state of the heel (32) in which the ridge (24) of the cord (2) is already attached to the reinforcement member (4) and the reinforcement member lid (42) is visible is shown. The hind limb (32) in front of the right hand shows the hind limb (32) in a state where the cord (2) is not yet inserted and the reinforcing member is not loaded.
More specifically, the ridge (24) of the umbilical cord (2) inserted into the heel fixing hole (34) of the front heel (31) of the base shown in FIG. 4 is the reinforcement member main body (41) of the reinforcement member (4). ) Is inserted from the heel insertion opening (46), and the heel (24) is arranged in the heel installation section (47) so that the space of the heel insertion opening (46) straddles the neck (25) of the cord (2). . Then, by covering from above with the reinforcing member lid (42), the heel (24) is enclosed so that the end of the umbilical cord (2) has the original “T” shape, and the heel fixing hole (34) The reinforcing member (4) is housed inside.
The rear heel (32) in the right back of FIG. 4 houses the ridge (24) of the cord (2) in the reinforcement member (4), and the reinforcement member main body (41) with the reinforcement member lid (42). A state is shown in which the reinforcing member (4) has been accommodated in the cover fixing hole (34). The rear heel (32) in front of the right hand is still in a state before the ridge (24) of the cord (2) can be inserted, and the heel fixing hole (34) of the posterior heel (32) is visible from the back of the table. Indicates the state.
次に図5の(5−1)、(5−2)で補強部材(4)の構造を説明し、(5−3)、(5−4)で補強部材(4)に鼻緒の端の鍔(24)を装着する説明をする。さらに(5−5)、(5−6)には補強部材(4)と台の間に入れて鼻緒の長さ調整をする調整部材(5)の説明をする。
まず、(5−1)にて補強部材(4)の構成を説明すると、補強部材(4)は補強部材本体(41)と補強部材蓋(42)で構成され、補強部材本体(41)のカシメ突起部(43)を補強部材蓋(42)のカシメ穴(44)に通してカシメ突起部(43)の先頭を補強部材蓋(42)のカシメ穴(44)の上から潰してカシメることにより、補強部材本体(41)に対して補強部材蓋(42)を回動可能に一体化する。なお、(5−1)ではカシメで補強部材本体(41)と補強部材蓋(42)を繋いでいるが、ビス止めなど他の方法で一体化しても問題ないし、後に述べる図6のように本体も蓋も一体成型で補強部材(4)を準備することもできる。
次に(5−2)は(5−1)の補強部材(4)をひっくり返した図で、回動可能に一体化された補強部材蓋(42)の裏には固定爪(45)が設けられており、補強部材本体(41)の馬蹄形の開口部である鍔挿入口(46)の幅より少しせまい間隔で固定爪(45)の間隔を設けておくことで、補強部材蓋(42)を補強部材本体(41)に重ねるように回動させると、固定爪(45)がこの鍔挿入口(46)の空間に引っかかり補強部材蓋(42)が補強部材本体(41)の所定位置に固定されるようになる状態を(5−2)で図示している。
Next, the structure of the reinforcing member (4) will be described with reference to (5-1) and (5-2) in FIG. 5, and the reinforcing member (4) will be connected to the reinforcing member (4) with reference to (5-3) and (5-4). A description will be given of wearing the bag (24). Further, in (5-5) and (5-6), the adjustment member (5) for adjusting the length of the umbilical cord inserted between the reinforcing member (4) and the base will be described.
First, the configuration of the reinforcing member (4) will be described in (5-1). The reinforcing member (4) includes a reinforcing member main body (41) and a reinforcing member lid (42). The caulking protrusion (43) is passed through the caulking hole (44) of the reinforcing member lid (42), and the leading end of the caulking protrusion (43) is crushed from above the caulking hole (44) of the reinforcing member lid (42). Thus, the reinforcing member lid (42) is integrated with the reinforcing member main body (41) so as to be rotatable. In (5-1), the reinforcing member main body (41) and the reinforcing member lid (42) are connected by caulking, but there is no problem even if they are integrated by other methods such as screwing, as shown in FIG. The reinforcing member (4) can be prepared by integrally molding the main body and the lid.
Next, (5-2) is a diagram in which the reinforcing member (4) of (5-1) is turned over, and a fixing claw (45) is provided on the back of the reinforcing member lid (42) integrated so as to be rotatable. The reinforcing member lid (42) is provided by providing a space between the fixing claws (45) with a narrow gap slightly smaller than the width of the heel insertion opening (46) which is a horseshoe-shaped opening of the reinforcing member body (41). ) Is rotated so as to overlap the reinforcing member main body (41), the fixing claw (45) is caught in the space of the flange insertion port (46) and the reinforcing member lid (42) is positioned at a predetermined position of the reinforcing member main body (41). A state of being fixed to (5-2) is illustrated.
次に(5−3)と(5−4)にて補強部材(4)に鼻緒の端の鍔(24)を装着する説明をすると、(5−3)で図示するように補強部材本体(41)には鍔挿入口(46)と鍔設置部(47)が設けられており、鼻緒の端の鍔(24)は補強部材本体(41)に対して、この鍔挿入口(46)の馬蹄形の開口部を利用して補強部材本体(41)の横から挿入し、鍔設置部(47)に鼻緒の鍔(24)を設置して、その上から補強部材蓋(42)で補強部材本体(41)を覆うことで鼻緒の鍔(24)が補強部材(4)から外れないようになる。補強部材(4)に鍔(24)を設置した後は、先の図4で説明したように、台(3)の前壺(31)または後壺(32)の鍔固定穴(34)に、この鼻緒と一体化した補強部材(4)を収納する。
鍔設置部(47)に設置された鍔(24)は、本来の形状である「T」字型を維持したまま補強部材蓋(42)で覆われるため、先に述べた図(3−2)のように、鍔固定穴(34)の空間で鍔(24)が「へ」の字の形状に変化するゆとりの空間が無い状況になる。よって、鼻緒(2)が台(3)から人力で抜く方向に引っ張られても、補強部材本体(41)と補強部材蓋(42)で囲われて鍔設置部(47)の中で鍔(24)は「T」字型を維持することになり、台(3)に対して鼻緒(2)の固定を補強することになる。(5−3)は鍔(24)を補強部材(4)に設置する前の状態を示した図であり、(5−4)は補強部材(4)に鍔(24)を設置した後の状態を図示している。
ここで、補強部材(4)の径と鍔固定穴(34)の径については、鍔固定穴(34)の径を補強部材(4)の径より若干大きくし、台(3)のクッション性で装着保持できる程度のゆとりを持たせて設計しておくのが好ましい。なお、実施例1の補強部材(4)はポリカーボネート(PC)、ポリプロピレン(PP)、ABS樹脂、金属などの部材で製作しているが、補強部材(4)の目的が得られる部材であればこれ以外の部材でも何ら支障はない。
Next, in (5-3) and (5-4), description will be given of attaching the ridge (24) at the end of the cord to the reinforcing member (4). As shown in (5-3), the reinforcing member main body ( 41) is provided with a heel insertion port (46) and a heel installation portion (47), and the ridge (24) at the end of the umbilical cord is connected to the reinforcing member main body (41) with respect to the heel insertion port (46). Inserting from the side of the reinforcing member main body (41) using the horseshoe-shaped opening, installing the snare ridge (24) in the heel installing portion (47), and reinforcing member with the reinforcing member lid (42) from above By covering the main body (41), the snare ridge (24) is prevented from being detached from the reinforcing member (4). After installing the collar (24) on the reinforcing member (4), as explained in FIG. 4 above, in the collar fixing hole (34) of the front collar (31) or the rear collar (32) of the base (3). The reinforcing member (4) integrated with the cord is housed.
Since the heel (24) installed in the heel installation section (47) is covered with the reinforcing member lid (42) while maintaining the "T" shape which is the original shape, the above-described figure (3-2) ), There is no space in which the heel (24) changes to the shape of the “he” in the space of the heel fixing hole (34). Therefore, even if the cord (2) is pulled from the table (3) by human power, it is surrounded by the reinforcing member main body (41) and the reinforcing member lid (42), and the heel ( 24) will maintain the “T” shape and will reinforce the fixation of the umbilical cord (2) to the platform (3). (5-3) is a view showing a state before the flange (24) is installed on the reinforcing member (4), and (5-4) is after the flange (24) is installed on the reinforcing member (4). The state is illustrated.
Here, regarding the diameter of the reinforcing member (4) and the diameter of the flange fixing hole (34), the diameter of the flange fixing hole (34) is slightly larger than the diameter of the reinforcing member (4), and the cushioning property of the base (3) It is preferable to design it with a clearance that allows it to be mounted and held. In addition, although the reinforcement member (4) of Example 1 is manufactured with members, such as a polycarbonate (PC), a polypropylene (PP), an ABS resin, and a metal, if it is a member which can obtain the objective of a reinforcement member (4), There is no problem with other members.
次に(5−5)と(5−6)にて調整部材(5)の説明をすると、調整部材(5)は、補強部材本体(41)と同じように空間部分で鼻緒(2)の首部(25)を跨ぐように差し込み、補強部材(4)を台(3)の鍔固定穴(34)に装填するときに、台(3)と補強部材(4)の間に挟まれる状態で使う。
(5−5)で示すように、補強部材(4)の下に差し込む調整部材(5)は、鼻緒(2)の鍔(24)を補強部材(4)に格納したあとでも鼻緒(2)の首部(25)に差し込めるように開口部があり、台(3)と補強部材(4)との間に任意の枚数で差し込むことが可能で、補強部材(4)と共に鍔固定穴(34)に収納する。
(5−6)では補強部材(4)の下に2枚の調整部材(5)が差し込まれた状態を図示しており、例えば調整部材(5)の厚さを1mmとするならば、2枚の調整部材(5)を追加することで補強部材(4)に2mmを加えた鼻緒調整幅(51)を確保することになる。
これは鼻緒付き履物(1)の台(3)の中に鼻緒(2)の鍔(24)を2mm深く挿げることを意味しており、台(3)の表側に現れる鼻緒(2)の長さを2mm短くすることが出来ることになる。
Next, the adjustment member (5) will be described in (5-5) and (5-6). The adjustment member (5) is the same as the reinforcement member main body (41) in the space portion of the cord (2). When it is inserted so as to straddle the neck (25) and the reinforcing member (4) is loaded into the collar fixing hole (34) of the base (3), it is sandwiched between the base (3) and the reinforcing member (4). use.
As shown by (5-5), the adjusting member (5) inserted under the reinforcing member (4) can be used even after the ridge (24) of the cord (2) is stored in the reinforcing member (4). There is an opening so that it can be inserted into the neck portion (25), and any number of plates can be inserted between the base (3) and the reinforcing member (4). ).
(5-6) shows a state in which two adjusting members (5) are inserted under the reinforcing member (4). For example, if the thickness of the adjusting member (5) is 1 mm, 2 By adding the sheet adjustment member (5), the ridge adjustment width (51) obtained by adding 2 mm to the reinforcing member (4) is secured.
This means that the foot (24) of the cord (2) can be inserted 2mm deep into the platform (3) of the footwear (1) with the cord, and the cord (2) that appears on the front side of the platform (3) Can be shortened by 2 mm.
鼻緒付き履物(1)には鍔(24)を挿げる壺は3か所あるので、各々の壺ごとに鼻緒(2)の端の鍔(24)の固定深さを、この調整部材(5)の枚数によって任意に調整できるので、ユーザが自由に鼻緒(2)の長さを調節することが可能となる。
人の足は各々で足のサイズが異なるのと同様に足の甲の高さにもバラつきがあり、且つ一人の足であっても左右に微妙なサイズ違いや変形があり、履物を購入するときに1足の靴を左右で別サイズのものを欲しがる人もいれば、運動靴の幅を引き締める紐の締め具合を左右の足で違う引き締め方をする人もいる。
本願発明では、鼻緒(2)を固定するときに各々の端部で調整部材(5)を使用して長さ調整が可能となるため、右足と左足で鼻緒長さを違うものにもできるし、片方の鼻緒(2)の横緒(22)を、左右の後壺(32)で違う長さに調整することも可能である。それによって、人それぞれの足にフィットするように、鼻緒(2)の長さや肌への密着感のバランスを各自の好みで微調整できるようになる。
ここで、実施例1の調整部材(5)は合成ゴム、天然ゴム、金属などの硬い固形物であって、所定の厚みを持つ部材を加工して作られたもの(たとえば厚さ1mm)であって、その目的が得られる場合には他の部材でも特に問題はない。この鼻緒調整幅(51)については、補強部材本体(41)の鍔設置部(47)の下の肉厚、いわゆる(5−5)で示す鼻緒調整幅(51)に相当する部分の、肉厚が異なる補強部材(4)を準備した場合も、鼻緒の長さ調整においては同じ目的を果たすことが可能である。
Since there are three heels in which the heel (24) can be inserted into the footwear (1) with a umbilical cord, the fixing depth of the heel (24) at the end of the umbilical cord (2) is set to this adjustment member ( Since it can be arbitrarily adjusted according to the number of items 5), the user can freely adjust the length of the cord (2).
Each person's foot has the same size as the foot, but the height of the back of the foot also varies, and even a single foot has subtle size differences and deformations on the left and right, so buy footwear. Some people want a pair of shoes with different sizes on the left and right, and other people use different ways to tighten the laces that tighten the width of the athletic shoes.
In the present invention, since the length can be adjusted by using the adjustment member (5) at each end when fixing the cord (2), the length of the cord can be different between the right foot and the left foot. It is also possible to adjust the length (22) of one umbilical cord (2) to a different length between the left and right rear limbs (32). As a result, the length of the umbilical cord (2) and the balance of the feeling of close contact with the skin can be finely adjusted according to personal preferences so as to fit each person's foot.
Here, the adjusting member (5) of Example 1 is a hard solid material such as synthetic rubber, natural rubber, metal, etc., and is made by processing a member having a predetermined thickness (for example, 1 mm thick). If the purpose can be obtained, there is no particular problem with other members. With respect to the nose cord adjustment width (51), the thickness of the portion corresponding to the nose cord adjustment width (51) indicated by the so-called (5-5) thickness of the reinforcing member main body (41) under the heel installation portion (47). Even when reinforcing members (4) having different thicknesses are prepared, it is possible to achieve the same purpose in adjusting the length of the nose.
図6は補強部材を本体と蓋に分けることなく一体型で成形する状況を示している。
図5の説明で述べた補強部材(4)は、補強部材本体(41)と補強部材蓋(42)で構成されており、補強部材本体(41)に鍔(24)を設置するときには、補強部材蓋(42)を回動して補強部材本体(41)の上を開き、鍔挿入口(46)の開口部から鼻緒(2)の首部(25)を差し入れて、鍔設置部(47)の溝状の隙間に鍔(24)を落し込むように設置し、補強部材蓋(42)を回動して鍔(24)を四方から覆う形で補強部材(4)に収納していた。
それに対して図6の補強部材は本体と蓋を一体化した構造であり、図ではこれまでの分離型と区別がつくように補強部材蓋(42)の符号を付けているが、回動する必要もなく鍔(24)を容易に設置できる構造としている。
(6−1)は鍔(24)を設置する前で、(6−2)は設置後を図示しており、詳しく述べると、図5で説いた補強部材蓋(42)は一体化され鍔挿入口(46)と鍔設置部(47)を有する補強部材本体(41)、これすなわち補強部材(4)である。(6−1)のように鍔(24)の横から鍔挿入口(46)の開口部より差し込み、(6−2)のように鍔(24)が横滑りして鍔設置部(47)の奥に接するように設置すれば、鍔(24)は上下と一側面の三面を囲われることで鍔(24)のT字型は保持され、(6−2)の状態で図4のように台(3)の鍔固定穴(34)に収納することで、台(3)に対して鼻緒(2)の固定を補強することになる。
FIG. 6 shows a state in which the reinforcing member is molded as an integral type without dividing it into a main body and a lid.
The reinforcing member (4) described in the explanation of FIG. 5 is composed of a reinforcing member main body (41) and a reinforcing member lid (42). When the ridge (24) is installed on the reinforcing member main body (41), the reinforcing member (4) is reinforced. The member lid (42) is rotated to open the top of the reinforcing member main body (41), and the neck portion (25) of the cord (2) is inserted from the opening of the heel insertion port (46), so that the heel installation portion (47) The trough (24) was installed so as to drop into the groove-shaped gap, and the stiffening member lid (42) was rotated so as to cover the trough (24) from four directions and stored in the reinforcing member (4).
On the other hand, the reinforcing member in FIG. 6 has a structure in which the main body and the lid are integrated. In the figure, the reinforcing member lid (42) is labeled so as to be distinguished from the conventional separation type, but it rotates. There is no need for the structure so that the bag (24) can be easily installed.
(6-1) is before the installation of the cage (24), and (6-2) is after the installation. Specifically, the reinforcing member lid (42) described in FIG. A reinforcing member main body (41) having an insertion port (46) and a hook installation portion (47), that is, a reinforcing member (4). As shown in (6-1), it is inserted from the side of the bowl (24) through the opening of the bowl insertion port (46), and the bowl (24) slides sideways as shown in (6-2). If it is installed so as to be in contact with the back, the heel (24) is surrounded by the three sides of the top and bottom and one side, so that the T-shape of the heel (24) is maintained, and in the state of (6-2) as shown in FIG. By storing in the heel fixing hole (34) of the base (3), the fixation of the cord (2) to the base (3) is reinforced.
これまで図2から図6で説明したように、実施例1は、鼻緒(2)の端の鍔(24)をひねって台(3)の鍔挿入穴(33)に素手の力で鼻緒(2)を挿げて、鍔(24)が鍔固定穴(34)に入って本来の鍔(24)の形状に戻ることで台(3)に鼻緒(2)が固定され、その鍔(24)が鼻緒(2)を引き抜く力によって湾曲することで、素手の力で台から鼻緒を外すことが可能なため、ユーザが簡単に鼻緒(2)を交換出来る。
その鼻緒(2)の固定をさらに確実なものにするために、補強部材(4)を用いて補強することが出来る。
そして調整部材(5)を用いることで鼻緒の長さを任意に調整することも可能になるので、ユーザは実施例1の鼻緒付き履物(1)を履くシチュエーションに合わせて、最適な色柄の鼻緒(2)と最適な色や形状の台(3)の組合せを自分で選び、簡単に鼻緒交換を行えるとともに、鼻緒(2)の長さ調整も自由に調節できるようになり、今までの鼻緒付き履物より使い勝手の良い新たな鼻緒付き履物(1)を手にすることが可能になる。
As described above with reference to FIGS. 2 to 6, the first embodiment twists the heel (24) at the end of the umbilical cord (2) and twists it into the heel insertion hole (33) of the pedestal (3) with bare hands. 2) is inserted, and the ridge (24) enters the heel fixing hole (34) and returns to the original shape of the heel (24), thereby fixing the cord (2) to the base (3). ) Bends by the force that pulls out the umbilical cord (2), so that it is possible to remove the nasal cord from the table with the power of bare hands, so that the user can easily replace the umbilical cord (2).
In order to further secure the umbilical cord (2), it can be reinforced using the reinforcing member (4).
Since the length of the umbilical cord can be arbitrarily adjusted by using the adjusting member (5), the user can select an optimal color pattern according to the situation of wearing the knitted footwear (1) of the first embodiment. You can choose the combination of the umbilical cord (2) and the optimal color and shape (3) by yourself, and you can easily change the umbilical cord and adjust the length of the umbilical cord (2) freely. It becomes possible to obtain a new footwear with a nose (1) that is more convenient than footwear with a nose.
図7では、従来品の鼻緒と本願の鼻緒を挿げる状態を図示し、計測データにより比較した詳細を説明する。
鼻緒付き履物の鼻緒には布などで作られた和鼻緒と、塩化ビニールなどで作られたビーチサンダルなどに挿げられている鼻緒がある。また、台には日本古来の木製の台と、ゴム材やEVAなどの材質で作られた台がある。
ここでは塩化ビニールで作られた鼻緒と、EVAの台で構成する鼻緒付き履物について、鼻緒を台に挿げる時の力と鼻緒を台から抜く時の力の現状を説明し、その後に本願発明による鼻緒を台に挿げる時の力と鼻緒を台から抜く時の力の測定データを説明して、従来品と本願の違いを説明する。
まず、一般にビーチサンダルなどに用いられる鼻緒について説明すると、(7−1)のように鼻緒の端の鍔(24)の形状は円形状で構成されており、鼻緒の首部(25)の径は7〜8mmが一般的であり、円形状の鍔(24)の径は13〜15mm、大きいものでは19mmであって、その鍔の厚さは5mmほどのものがほとんどである。図では首部(25)を断面にした場合に四角形で描いているが、本願および従来品の形状には四角や丸があり計測に特に影響はないため、描写した形状に関わらず従来品に多い首部が丸い鼻緒でデータを出している。
また、鍔の円形状の寸法は歩行時に履物の前方に力が加わるため、前鍔は後鍔より若干大きくなっている状況にある。
この鍔(24)を台に刳りぬかれた穴、本願でいう鍔挿入穴(33)に挿入し、それに連なる鍔固定穴(34)に鍔(24)が収まることにより、鍔(24)は小さな鍔挿入穴(33)へと引き抜くことが困難となり鼻緒が台に固定される。
FIG. 7 illustrates a state in which the conventional cord and the present cord can be inserted, and details of the comparison based on the measurement data will be described.
There are two types of footwear with umbilical cords: Japanese lanyard made of cloth, etc., and velvet sandals made of vinyl chloride. In addition, there are two types of bases: ancient Japanese wooden bases and bases made of materials such as rubber and EVA.
This article explains the current situation of the force when inserting the umbilical cord into the pedestal and the force when removing the lanyard from the pedestal for footwear with a umbilical cord made of vinyl chloride and EVA pedestal. The measurement data of the force when inserting the cord on the table and the force when pulling the cord from the table according to the invention will be described to explain the difference between the conventional product and the present application.
First, a description of a chord generally used for flip flops, etc., as shown in (7-1), the shape of the collar (24) at the end of the chord is a circular shape, and the diameter of the neck (25) of the chord is The diameter of the circular ridge (24) is 13 to 15 mm, and the larger one is 19 mm, and the thickness of the ridge is about 5 mm in most cases. In the figure, the neck (25) is drawn in a square shape in cross section, but the shape of the present application and the conventional product has squares and circles and has no particular effect on measurement, so there are many in the conventional product regardless of the drawn shape. The neck has data with a round cord.
In addition, the circular shape of the heel has a situation where the front heel is slightly larger than the back heel because force is applied to the front of the footwear during walking.
When this ridge (24) is inserted into a hole drilled into the base, the heel insertion hole (33) referred to in the present application, and the ridge (24) fits into the heel fixing hole (34) connected thereto, the ridge (24) becomes It becomes difficult to pull out into the small heel insertion hole (33), and the thong is fixed to the table.
次に、EVAなど従来品の台に設けてある上記鼻緒の鍔が挿入される壺の形状について説明をすると、鼻緒の鍔が円形状であることから、壺の形状も丸穴で刳りぬかれており、台の表側の穴の径は、挿入される鼻緒の端の鍔に至る首部の径である7から8mmと同等の穴が穿孔されており、台の裏側の穴の径は、対応する鍔の円形状の径である13〜15mm、大きいもので19mmの穴が穿孔されている。そして、これらの穴は台の途中で各鍔が台の中で保持できるように、台の上部に所定の肉厚を残して空間の断面形状が「凸」の字のような形状に設けられる。
つまり、(7−1)のように空間形状が大小2段の穴で穿たれており、上の小さい穴の径、すなわち鍔挿入穴(33)の径は鼻緒の首部の径である7から8mm相当であり、下の大きい穴の径、すなわち鍔固定穴(34)の径は鼻緒の鍔の径である13〜15mm、大きいものでは19mmで構成され、鍔が台から抜けない台の止め部分、つまり空間形状が凸形状の壺の大小の穴の径の切り替わる段差の面に、鍔(24)が引っかかることで鼻緒は台から抜けなくなるわけだが、鍔固定穴(34)の深さを少なくとも鍔(24)の厚みが収まる深さとし、鍔挿入穴(33)に首部(25)が収まって、鼻緒の長さが台の上面で適切な長さになるように設計して製造し、商品として市場に出回っているのが実態である。
なお、今回の測定では従来品のビーチサンダルを計測材料としたが、一般にビーチサンダルについての鼻緒の抜け力は、履物業界では100ニュートン(10kg)以上あれば良しとされ、業界団体の化学物質評価研究機構では130ニュートン(13kg)でOKとしている。
ここでkgとニュートンの関係は、1kg=9.80665ニュートン であり、引っ張り強さ測定器ではニュートン単位でわかりづらいので、下記の説明では一般に慣れたkg単位を( )の中で参考までに記載して説明をしている。
また、今回の測定に用いた硬度計はASKER「高分子計器株式会社」のデュロメータ硬度計、引っ張り強さ測定器はSHIMADZUのオートグラフAGS−X5KNを用いている。
Next, a description will be given of the shape of the ridge that is inserted in the conventional pedestal such as EVA, and the shape of the ridge is rounded. The diameter of the hole on the front side of the base is a hole equivalent to 7 to 8 mm, which is the diameter of the neck leading to the ridge at the end of the inserted cord, and the diameter of the hole on the back side of the base is compatible A hole having a diameter of 13 to 15 mm, which is a circle, and a large one having a diameter of 19 mm is drilled. And these holes are provided in a shape like a “convex” shape in the cross section of the space, leaving a predetermined thickness on the upper part of the table so that each hook can be held in the table in the middle of the table .
That is, as shown in (7-1), the space shape is perforated with two large and small holes, and the diameter of the small hole above, that is, the diameter of the heel insertion hole (33) is from 7 which is the diameter of the neck of the nose. It is equivalent to 8mm, and the diameter of the lower large hole, that is, the diameter of the heel fixing hole (34) is 13 to 15mm which is the diameter of the ridge of the umbilical cord, and the larger one is 19mm. The ridge (24) is caught on the surface of the step where the diameter of the large and small holes of the ridge with the convex shape of the space changes, so that the thong does not come off the base, but the depth of the heel fixing hole (34) Designed and manufactured so that at least the thickness of the heel (24) fits, the neck (25) fits in the heel insertion hole (33), and the length of the nose is an appropriate length on the upper surface of the table, The reality is that it is on the market as a product.
In this measurement, the conventional sandal sandals were used as the measurement material. However, it is generally accepted that the snagging force of the beach sandals is 100 Newtons (10 kg) or more in the footwear industry. The research organization is OK at 130 Newton (13 kg).
Here, the relationship between kg and Newton is 1 kg = 9.80665 Newton, and it is difficult to understand in Newton units with the tensile strength measuring instrument. Therefore, in the following explanation, generally used kg units are listed in () for reference. And explain.
In addition, the hardness meter used for this measurement is a durometer hardness meter of ASKER “Polymer Keiki Co., Ltd.”, and the tensile strength measuring device is a SHIMADZU autograph AGS-X5KN.
さて、最初に測定時の条件を説明すると、従来の鼻緒付き履物で鼻緒を挿げる場合の力と、抜ける場合の力を測定するにあたって使用したビーチサンダルは、台の素材は硬度55度のEVAを用い、壺の穿孔穴の径は8.5mm、壺の大小の穴の段差から台の表面までの肉厚は9mm。すなわち(7−1)で示すように鍔挿入穴(33)の径が8.5mmで深さは9mmで測定している。
鼻緒の素材は高度72度の塩化ビニール、鼻緒の前緒を使用し、首部(25)の径は7mm、鍔の径は19mm、鍔の厚さは5mmで測定を行った。この条件にて従来の鼻緒を台に挿げる場合の力は、
91.4502ニュートン(9.32533kg)であった。
テスト方法としては、従来の鼻緒を挿げると同様に、鼻緒の端の鍔を専用の挿げ具の先端で挟み、この挟んだ挿げ具の端の状態を引っ張り強さ測定器で測定した。
一般に考えても解るように、台の壺の穿孔穴の径が8.5mmなので、ここに鍔の径の19mmを挿入することは容易ではない。このため、台の下から壺穴の中を通した挿げ具という治具の先端に、鼻緒の鍔を挟んで強引に機械的な力で瞬間的に、台の素材であるEVAの柔軟性を利用して引き込み、鼻緒を挿げるのが業界での今の製造技術である。今回の測定では(7−2)で示すように、台の下から壺穴の中を通した挿げ具の先端で鍔(24)をしっかりと挟ませ、鍔(24)を挟んだ挿げ具は上になった先端がチューリップの花のように広がった形状になり、下の根元はそれよりも細く鍔挿入穴(33)の径よりも細い。約91ニュートン(9Kg)の引っ張り力が瞬間的にかかることで、挿げ具のチューリップ状になった先端形状により、EVAの台の鍔挿入穴(33)は横に広げられ、挿げ具ごと鍔(24)を一気に通し、鍔(24)が台を通り抜けたところで挿げ具の先端は傘のように開いて鍔(24)から外れ、鼻緒が台の上側に引き戻され履物としての用をなすように定位置に上がることで、鍔(24)は鍔固定穴(34)に収まって鼻緒が台に挿げられた状態になる。
また、従来の台から鼻緒を引き抜く場合の力については、挿げた鼻緒を上から引っ張って抜けるか調べたが、測定では約241ニュートン(25kg)で鼻緒が千切れた。この測定値は上記業界団体の鼻緒の抜け値である130ニュートン(13kg)より大きな値であり、塩化ビニールで作られた鼻緒の材質のほうが弱く、千切れる結果に終わった。
Now, the conditions at the time of measurement will be explained first. The beach sandals used to measure the force when inserting the umbilical cord with footwear with conventional umbilical cord and the force when detaching it are the material of the base is 55 degrees hardness Using EVA, the diameter of the perforated hole of the scissors is 8.5 mm, and the thickness from the step of the large and small holes of the scissors to the surface of the table is 9 mm. That is, as shown by (7-1), the diameter of the scissors insertion hole (33) is 8.5 mm and the depth is 9 mm.
The material of the umbilical cord was vinyl chloride at an altitude of 72 degrees, and the forerunner of the umbilical cord. The neck (25) had a diameter of 7 mm, a heel diameter of 19 mm, and a heel thickness of 5 mm. In this condition, the power to insert the conventional cord on the table is
91.4502 Newton (9.332533 kg).
As a test method, just as with a conventional umbilical cord, the ridge at the end of the umbilical cord is pinched with the tip of a dedicated insertion tool, and the state of the end of the inserted insertion tool is measured with a tensile strength measuring instrument. did.
As generally understood, since the diameter of the perforation hole of the base collar is 8.5 mm, it is not easy to insert the diameter of 19 mm of the collar here. For this reason, the flexibility of EVA, which is the material of the table, is instantaneously forced by mechanical force with a chin cord between the tip of a jig called an insertion tool that passes through the hole from the bottom of the table. The current manufacturing technology in the industry is to pull in and use the cord. In this measurement, as shown in (7-2), hold the heel (24) firmly with the tip of the insertion tool that passed through the hole from the bottom of the base, and insert the heel (24). The tool has a shape in which the tip at the top expands like a tulip flower, and the bottom of the tool is narrower than that and smaller than the diameter of the eyelid insertion hole (33). The pulling force of about 91 Newton (9Kg) is momentarily applied, and the tulip-shaped tip shape of the insertion tool widens the heel insertion hole (33) of the EVA base to the side. Pass the heel (24) at a stretch, and when the heel (24) passes through the base, the tip of the insertion tool opens like an umbrella and comes off the heel (24), and the thong is pulled back to the upper side of the base and used as footwear. As a result, the heel (24) is placed in the heel fixing hole (34) and the nose is inserted into the platform.
In addition, as for the force when pulling the umbilical cord from the conventional table, it was examined whether the inserted nasal cord was pulled out from above, but in the measurement, the nasal cord was cut off at about 241 Newton (25 kg). This measured value is larger than 130 Newton (13 kg), which is the missing value of the industry association, and the result is that the material of the nose made of vinyl chloride is weaker and is cut off.
次に、本願発明の鼻緒を台に挿げる場合と引き抜く場合についての測定条件だが、鼻緒は上記従来品と同じものを使用し、首部の径は7mm、鍔の厚さは5mm、鍔の径は19mmの円形の鍔の両端を切断して長さ19mm、幅7mmの長形状の鍔にしたものを本願の鍔として測定を行った。台の壺の穿孔穴は上記従来品のテストと同様に、鍔挿入穴の径が8.5mmで深さは9mmで測定をし、
鼻緒を台に挿げる時の力については、43.5956ニュートン(4.44551kg) であり、
鼻緒を台から引き抜く力については、55.4427ニュートン(5.65358kg) であった。
この鼻緒を挿げるときの測定は、鍔の先に小さな穴を開け、そこに紐を通して引っ張り測定器で台の裏から引っ張ることで測定をした。
この測定結果から、従来の円形鍔の場合は挿げ具を用いて機械的な力で約91ニュートン(9kg)を要していたものが、長形状の鍔では半分の44ニュートン(4kg)で挿げられたことが数値として確認できた。
また、鍔を台から引き抜く場合は、従来の円形状の鍔の場合は先に塩化ビニールの鼻緒の方が千切れて鍔を抜くところまでは至らなかったが、長形状の鍔の場合は鍔の形状が「へ」の字型に変形しやすいこともあり、55ニュートン(6kg)の力で引き抜けることが数値結果で証明できた。
Next, the measurement conditions for the case where the cord of the present invention is inserted into the table and the case where the cord is pulled out are the same as those in the conventional product, the neck diameter is 7 mm, the thickness of the collar is 5 mm, The diameter of the 19 mm circular ridge was cut at both ends to obtain a long ridge having a length of 19 mm and a width of 7 mm. In the same way as the test of the above-mentioned conventional product, the diameter of the punch insertion hole is 8.5 mm and the depth is 9 mm.
The force when inserting the cord on the table is 43.5956 Newton (4.44551 kg),
The force for pulling the thong from the table was 55.4427 Newton (5.665358 kg).
The measurement when inserting the cord was made by making a small hole at the tip of the heel and pulling it through the string and pulling it from the back of the table with a measuring instrument.
From this measurement result, in the case of the conventional circular ridge, it took about 91 Newton (9 kg) by mechanical force using the insertion tool, but in the case of the long fold, it was half of 44 Newton (4 kg). It was confirmed as a numerical value that it was inserted.
In addition, when pulling out the cocoon from the stand, the conventional circular cocoon had not yet reached the point where the vinyl chloride thong was cut off and the cocoon was pulled out. The shape of can easily be deformed into a “he” shape, and it was proved by numerical results that it could be pulled out with a force of 55 Newton (6 kg).
測定数値を見比べたら、従来品の鼻緒を挿げるときの力は91ニュートン(9Kg)で抜くときは241ニュートン(25Kg)であり、本願発明の挿げるときの力は44ニュートン(4Kg)で抜くときは55ニュートン(6Kg)であり、本願の鼻緒は従来品の半分以下の力で挿げて、それと大差ない力で抜けると受け止められる。
素手で鼻緒を台に挿げるという本願の目的に照らし合わせて測定数値と鼻緒の着脱方法を見たとき、(7−1)のように径が8.5mmの鍔挿入穴(33)に、円形の径が19mmの鍔(24)を人の手で挿入することは困難であり、(7−2)のように挿げ具の挟む力と、機械の引き抜く力、そして何よりチューリップ状の形状で細い側から太い側へと鍔挿入穴(33)を押し広げながら挿入される仕組みと強力な力を総合しないことには、従来の円形19mmの鍔(24)を8.5mmの鍔挿入穴(33)に挿入することは、素手だけの操作と力では不可能である。
本願発明の鼻緒は(7−3)のように鍔(24)の端面が長形で、測定には長さ19mm、幅7mm、厚さ5mmの長形状の鍔(24)で測定した結果のように、首部(25)に添わせるように鍔(24)を縦にひねることで鍔挿入穴(33)に通すときのサイズが小さくなるため、44ニュートン(4Kg)という人の素手の力で容易に挿げられる鼻緒を実現可能とした。
鼻緒を抜く力に関しても、鍔(24)が湾曲することで鍔挿入穴(33)から55ニュートン(6Kg)という人の素手の力で抜くことを可能とし、その挿げた鼻緒が不用意に抜けないために補強部材で囲うことで鍔(24)の湾曲を防止して鼻緒の固定を補強し、且つ鼻緒の長さ調整も可能としたのが本願発明である。
なお、一般に人の素手での押す力や引き抜く力は、独立行政法人、製品評価技術基盤機構の人間特性データベースの上肢操作力でも示されているように60ニュートン前後の値である。
よって、上記の本願の長形状の鍔を台へ挿げる力、および鼻緒を台から引き抜く力の値は、人間の素手の力相当の値であり、治具を用いなくても鼻緒を台に挿げて外せることを測定結果からも証明できている。

Comparing the measured values, the force when inserting the cord of a conventional product is 241 Newton (25 Kg) when pulling out with 91 Newton (9 Kg), and the force when inserting according to the present invention is 44 Newton (4 Kg) When it is pulled out, it is 55 Newton (6Kg), and the cord of the present application can be accepted when it is inserted with less than half the force of the conventional product and with a force not much different from that.
In the light of the purpose of the present application of inserting the umbilical cord into the table with bare hands, when looking at the measured value and the detachment method of the umbilical cord, as shown in (7-1), in the heel insertion hole (33) with a diameter of 8.5 mm It is difficult to manually insert a heel (24) having a circular diameter of 19 mm, and the force of pinching of the insertion tool, the force of pulling out the machine as in (7-2), and above all, the tulip shape In order not to combine the powerful force and the mechanism that is inserted while pushing the heel insertion hole (33) from the thin side to the thick side in the shape, 8.5mm 鍔 insertion of the conventional circular 19mm 鍔 (24) Inserting into the hole (33) is impossible with the operation and force of bare hands.
The thong of the present invention has a long end face of the heel (24) as shown in (7-3), and the measurement results are obtained by measuring with a long ridge (24) having a length of 19 mm, a width of 7 mm, and a thickness of 5 mm. Thus, the size when passing the scissors insertion hole (33) by twisting the scissors (24) vertically so as to follow the neck (25) is reduced, so the force of the person's bare hands of 44 Newton (4Kg) A string that can be easily inserted is realized.
With regard to the force to pull the umbilical cord, the heel (24) is curved so that it can be pulled out from the heel insertion hole (33) with the force of a human hand of 55 Newton (6Kg). Therefore, it is the present invention that the ribs (24) are prevented from being bent to reinforce the fixation of the umbilical cord, and the length of the umbilical cord can be adjusted by enclosing it with a reinforcing member.
In general, the pushing force or pulling force with a human hand is a value of around 60 Newtons, as indicated by the upper limb operation force of the human characteristics database of the Incorporated Administrative Agency and Product Evaluation Technology Infrastructure.
Therefore, the value of the force for inserting the long cocoon of the present application into the table and the force for pulling the string from the table are values equivalent to the force of a human hand, and the value of the cord can be adjusted without using a jig. It can be proved from the measurement result that it can be inserted and removed.

図8は実施例2の鼻緒付き履物の斜視図であり、鼻緒付き履物(1)は鼻緒(2)と台(3)で構成され、鼻緒(2)は図1で説明した本発明の鼻緒と同一、つまり鼻緒の前緒(21)と2つの後緒(23)の端には共に長形の鍔(24)が設けられている。
図8で解るように、実施例2では台(3)に設けている前壺(31)と後壺(32)の形状が実施例1とは異なる。実施例1(図2参照)では前壺(31)および後壺(32)は各々丸型の鍔挿入穴(33)と鍔固定穴(34)で構成されていたが、実施例2の鍔挿入穴(33)は、鼻緒の鍔(24)の形に見合った長形の刳りぬき穴で台(3)の上から下まで貫通した穴として設けられ、鍔固定穴(34)は台(3)の裏面から所定の深さで、貫通している鍔挿入穴(33)とは90度交差した向きで、鍔(24)の形に見合った長形の空間を設けている。台(3)の裏面から見れば、鍔挿入穴(33)と鍔固定穴(34)が90度交差して、十文字の形での穴が台の途中まで設けられた構造になる。
ここで、台(3)の裏面からの所定の深さとは、台における鼻緒の鍔(24)を台から抜けなくするように台の肉厚を確保したうえで、鍔(24)の厚みが収まる鍔固定穴(34)の深さである。
なお、図8の鼻緒の鍔(24)は、鼻緒(2)の前後長手方向に対して横に長い状態で準備されているにも関わらず、対応する台(3)の鍔挿入穴(33)は、台(3)の前後長手方向に等しく長形に設けられている。そして、鼻緒の端の鍔(24)が挿げられた後に、鍔(24)を固定する穴である鍔固定穴(34)は、台の前後長手方向に対して90度交差し、鼻緒の鍔(24)と同じく横に長い向きに設けてある。
このように、まずは鼻緒の端をひねって、鼻緒の向きとは違う向きで台(3)に貫通されている鍔挿入穴(33)に鍔(24)を挿げた後、鼻緒(24)の端のひねりを元に戻して、本来の鍔(24)の向きで台(3)に所定の深さで穿たれている鍔固定穴(34)に鍔(24)を収めることで、台(3)に鼻緒(2)を挿げて固定させることが可能となる。
FIG. 8 is a perspective view of the footwear with umbilical cord of Example 2, the footwear with nasal cord (1) is composed of a umbilical cord (2) and a table (3), and the umbilical cord (2) is the nasal cord of the present invention described in FIG. In other words, a long ridge (24) is provided at the ends of the umbilical forehead (21) and the two backs (23).
As can be seen from FIG. 8, in the second embodiment, the shapes of the front heel (31) and the rear heel (32) provided on the table (3) are different from those in the first embodiment. In the first embodiment (see FIG. 2), the front kite (31) and the rear kite (32) are each composed of a round kite insertion hole (33) and a kite fixing hole (34). The insertion hole (33) is an elongated hole that matches the shape of the chin cord (24) and penetrates from the top to the bottom of the table (3). A long space corresponding to the shape of the ridge (24) is provided at a predetermined depth from the back surface of 3) and intersecting with the ridge insertion hole (33) penetrating through 90 degrees. When viewed from the back surface of the base (3), the hook insertion hole (33) and the hook fixing hole (34) intersect each other by 90 degrees so that a hole in the shape of a cross is provided partway through the base.
Here, the predetermined depth from the back surface of the pedestal (3) means that the thickness of the ridge (24) is determined after securing the thickness of the pedestal so that the ridges (24) of the cord on the pedestal are not removed from the pedestal. It is the depth of the collar fixing hole (34) which fits.
8 is prepared in a state that is long in the lateral direction with respect to the longitudinal direction of the cord (2), the rod insertion hole (33) of the corresponding base (3) is prepared. ) Is provided in an elongated shape equally in the longitudinal direction of the table (3). After the ridge (24) at the end of the nose is inserted, the heel fixing hole (34), which is a hole for fixing the ridge (24), intersects the longitudinal direction of the table by 90 degrees, Like the ridge (24), it is provided in a long horizontal direction.
In this way, first, twist the end of the umbilical cord, insert the heel (24) into the heel insertion hole (33) penetrating the platform (3) in a direction different from the direction of the nasal cord, and then The twist of the end is returned to the original position, and the heel (24) is placed in the heel fixing hole (34) drilled at a predetermined depth in the pedestal (3) in the original heel (24) direction. It becomes possible to insert and fix the cord (2) to 3).
図9では、この台(3)に対して鼻緒を挿入したり抜き出すときの状態を具体的に説明する。
まず、台(3)に鼻緒の前緒(21)を挿入する場合は、(9−1)で示しているように、鼻緒(2)を台(3)に対して90度向きをひねって、台の前壺(31)に貫通している鍔挿入穴(33)に、鼻緒の前緒(21)の端にある鍔(24)の向きを合わせて上から挿入する。そして、台(3)の裏側に鍔(24)が露出するまで貫通させた後、鼻緒(2)を元の向きに戻して、台(3)の前壺(31)の下部に設けられている鍔固定穴(34)に鍔を(24)収めることで、鼻緒(2)の前緒(21)が台(3)に挿げられ固定される。
次に(9−2)で後緒を台に挿げる方法を説明すると、後緒(23)の端をひねって台の後壺(32)に貫通している鍔挿入穴(33)に、鼻緒の後緒の端にある鍔(24)の向きを合わせて上から挿入する。そして、台(3)の裏側に鍔(24)が露出するまで貫通させた後、鼻緒(2)が台(3)の上で正しい向きになるよう鼻緒の端のひねって本来の向きに戻し、その鍔挿入穴(33)とは90度異なった角度に設けられている後壺(32)の鍔固定穴(34)に、鼻緒の後緒の鍔(24)を各々収めることで、鼻緒(2)の後緒(23)が台(3)に挿げられ固定される。
次に鼻緒(2)を台(3)から抜き出す場合の動作について説明すると、前緒、後緒など抜き出したい鼻緒(2)の端の各々を、台(3)の表側から裏側へと押し込むことで、鍔固定穴(34)に収まっている鍔(24)を台(3)の外へ露出させ、鼻緒(2)の端の向きを90度回転させることにより鍔固定穴(34)の向きだった鍔(24)を鍔挿入穴(33)の向きに合わせて引き上げることで、鼻緒(2)の端を台(3)から抜き出すことができる。
この操作を、鼻緒(2)の3つの鍔(24)に対して行えば、鼻緒(2)の端の前緒(21)および後緒(23)の鍔(24)を、台(3)から容易に取り外せる。
このように、本発明の鼻緒(2)は簡単な操作で台(3)に挿げたり取り外したりすることが出来るので、デザインの異なる鼻緒(2)と台(3)をユーザは必要に応じて簡単に交換することが可能となる。
In FIG. 9, the state at the time of inserting and extracting a cord to this stand (3) is demonstrated concretely.
First, when inserting the umbilical cord (21) into the platform (3), twist the umbilical cord (2) 90 degrees relative to the platform (3) as shown in (9-1). Then, the heel (24) at the end of the umbilical cord (21) is aligned and inserted from above into the heel insertion hole (33) penetrating the front heel (31) of the table. And after penetrating until the heel (24) is exposed on the back side of the base (3), the umbilical cord (2) is returned to the original direction and is provided at the lower part of the front heel (31) of the base (3). By storing the heel (24) in the heel fixing hole (34), the front (21) of the umbilical cord (2) is inserted and fixed to the base (3).
Next, in (9-2), the method of inserting the back into the base will be explained. Twist the end of the back (23) and insert it into the back insertion hole (33) passing through the back back (32) of the base. Align the direction of the heel (24) at the end of the umbilical cord and insert it from above. Then, after penetrating the back of the base (3) until the ridge (24) is exposed, twist the end of the nose back to the original orientation so that the nose (2) is in the correct orientation on the base (3). By placing the ridges (24) following the umbilical cord in the heel fixing holes (34) of the posterior heel (32) provided at an angle different from the heel insertion hole (33) by 90 degrees, (2) The back (23) is inserted into the base (3) and fixed.
Next, the operation when the cord (2) is extracted from the table (3) will be described. Each of the ends of the cord (2) to be extracted, such as the front and back, is pushed from the front side to the back side of the table (3). Then, the heel (24) contained in the heel fixing hole (34) is exposed to the outside of the base (3), and the direction of the heel fixing hole (34) is rotated by rotating the direction of the end of the nose (2) by 90 degrees. The end of the umbilical cord (2) can be extracted from the platform (3) by pulling up the heel (24) which is the same with the direction of the heel insertion hole (33).
If this operation is performed on the three ridges (24) of the umbilical cord (2), the ridge (24) at the front (21) and the posterior (23) of the end of the nasal cord (2) is placed on the platform (3). Easy to remove from.
As described above, the cord (2) of the present invention can be inserted into and removed from the table (3) by a simple operation, so that the user can use the cord (2) and the table (3) with different designs as needed. Can be easily replaced.
実施例2では、図9の説明で台(3)の鍔挿入穴(33)と鍔固定穴(34)の長形の向きについて述べたが、鼻緒(2)の各々の端をひねって挿げて最終的に鍔固定穴(34)に鍔(24)を収めたとき、鼻緒(2)が正しい向きで台(3)に固定されるようになれば良いのであって、図8のように鍔(24)の方向を横向きではなく、鼻緒(2)の長手方向と同じく縦に長い向きで鍔(24)を設けた場合は、台(3)の鍔固定穴(34)がその鍔(24)と同じ向きになるように所定の深さで設け、それに交差して連なる鍔挿入穴(33)が90度回転された向きで台(3)に貫通していれば、同じ操作で鼻緒(2)を台(3)に挿げて固定する構造になる。
そして、鍔挿入穴(33)と鍔固定穴(34)が交差して設けてある角度については、90度に限定するものではない。鼻緒(2)の端が硬くしっかりしていて、鍔(24)が鍔固定穴(34)から鍔挿入穴(33)へと安易に移動しない場合には、鍔挿入穴(33)と鍔固定穴(34)の角度は例え10度でも、本願の鼻緒付き履物(1)を使用するときに鍔(24)が鍔固定穴(34)から鍔挿入穴(33)へと移動しなければ、角度は最小限でも問題は無い。
また、鼻緒の鍔(24)の形状が長形以外の形状である場合には、台(3)の鍔挿入穴(33)と鍔固定穴(34)の形状は鼻緒の鍔(24)に合わせた形状で設け、例えばハート型の鍔(24)を鼻緒(2)の端に縦向きに設けたとすれば、台(3)に設ける鍔固定穴(34)は鍔(24)と同じハート型を縦向きで設けるが、鍔挿入穴(33)は縦向きでさえなければ、90度回転した横向きでも良いし10度から80度など、鼻緒(2)の端をひねって台(3)に挿げて鍔(24)が鍔固定穴(34)に固定できれば何ら問題は無い。
In the second embodiment, the elongated direction of the heel insertion hole (33) and the heel fixing hole (34) of the base (3) was described in the description of FIG. 9, but each end of the umbilical cord (2) is twisted and inserted. Finally, when the heel (24) is stored in the heel fixing hole (34), it is sufficient that the umbilical cord (2) is fixed to the base (3) in the correct orientation as shown in FIG. When the heel (24) is provided in the longitudinally long direction as in the longitudinal direction of the umbilical cord (2) rather than in the horizontal direction, the heel fixing hole (34) of the base (3) If it is provided at a predetermined depth so as to be in the same direction as (24), and the heel insertion hole (33) that intersects and extends through the base (3) in a direction rotated by 90 degrees, the same operation is performed. The umbilical cord (2) is inserted into the table (3) and fixed.
The angle at which the heel insertion hole (33) and the heel fixing hole (34) intersect is not limited to 90 degrees. If the end of the umbilical cord (2) is hard and firm and the heel (24) does not move easily from the heel fixing hole (34) to the heel insertion hole (33), the heel insertion hole (33) and the heel fixation Even if the angle of the hole (34) is 10 degrees, for example, when using the footwear (1) with the nose of the present application, if the heel (24) does not move from the heel fixing hole (34) to the heel insertion hole (33), There is no problem even if the angle is minimal.
In addition, when the shape of the chin cord (24) is a shape other than the long shape, the shape of the heel insertion hole (33) and the heel fixing hole (34) of the base (3) is the shape of the chin cord (24). For example, if a heart-shaped heel (24) is provided vertically at the end of the umbilical cord (2), the heel fixing hole (34) provided in the base (3) is the same heart as the heel (24). The mold is provided in the vertical direction, but if the heel insertion hole (33) is not in the vertical direction, it may be rotated horizontally by 90 degrees or by twisting the end of the nose (2), such as 10 degrees to 80 degrees, and the table (3) There is no problem if the hook (24) can be fixed to the hook fixing hole (34).
一例をあげると、鼻緒(2)の端の首部(25)の先端近くにピン穴を空け、その穴に硬い金属棒を差し込んで、断面が漢字の「中」の字のようにしてもそれが鍔(24)になる。図示していないが、「中」の字の形に鍔(24)を準備した場合、鍔挿入穴(33)は首部(25)が通る丸穴と、金属棒が通る切り込みを1本入れたような形で台に貫通穴を設ければ良い。図8や図9では台(3)に設けた鍔挿入穴(33)を長四角で描いているが、実際の加工工程では長四角より丸穴を空けるほうが簡単で作業効率が良い。
鼻緒付き履物(1)が木製など硬い部材であっても、丸穴を空けてその円周の一方向に貫通する直線の切り込みを空けて「中」の字の形で鍔挿入穴(33)を設ければ、台(3)の表面に鼻緒(2)が現れる部分が、一般的な丸穴から円形の首部(25)が露出することになり、細いまっすぐな切り込みは目立ちにくく鼻緒付き履物(1)の体裁が良くなる。
そして、「中」の字の形の鍔(24)は「中」の字の形の鍔挿入穴(33)を通り抜けた後に回転させ、金属棒が収まる直線の切り込みを任意の深さで設けるだけで用途をなす鍔固定穴(34)に、金属棒を収めることで鼻緒(2)を固定することができ、その直線の切り込みの向きは、貫通した鍔挿入穴(33)の切り込みと角度がずらしてさえあれば、10度から90度などいずれの角度で切り込みを設けても何ら問題なく、金属棒を収めることで鍔(24)を鍔固定穴(34)に収めることになり、鼻緒(2)を台(3)に固定することが可能である。
As an example, even if a pin hole is made near the tip of the neck (25) at the end of the cord (2), a hard metal rod is inserted into the hole, and the cross-section is like a “middle” character in Chinese characters. Becomes 鍔 (24). Although not shown, when the collar (24) is prepared in the shape of the "middle" character, the collar insertion hole (33) has a round hole through which the neck (25) passes and a notch through which the metal rod passes. A through hole may be provided in the table in such a manner. In FIG. 8 and FIG. 9, the eaves insertion hole (33) provided in the table (3) is drawn as a long square, but in an actual machining process, it is easier and more efficient to make a round hole than the long square.
Even if the footwear with nose (1) is a hard member such as wood, a hole is inserted in the shape of a “medium” by making a round cut and making a straight notch that penetrates in one direction of the circumference. , The part where the umbilical cord (2) appears on the surface of the base (3) will expose the circular neck (25) from the general round hole, and the thin straight notch is inconspicuous and the footwear with the chin The appearance of (1) is improved.
Then, the 中 (24) in the shape of “middle” is rotated after passing through the 鍔 insertion hole (33) in the shape of “middle”, and a straight cut into which the metal bar is accommodated is provided at an arbitrary depth. It is possible to fix the umbilical cord (2) by placing a metal rod in the heel fixing hole (34), which is used only by itself, and the direction of the straight cut is the angle and angle of the piercing hole (33) that penetrates As long as there is a shift, no problem will be caused by any angle such as 10 to 90 degrees, and the metal rod will be accommodated so that the collar (24) can be accommodated in the collar fixing hole (34). It is possible to fix (2) to the base (3).
図10では実施例2における鼻緒を挿げる手順の詳細、および実施例2で使用する調整部材(5)について断面図を交えて説明する。実施例2で鼻緒を挿げる方法についてはすでに図9で説明しているが、一つの壺と一つの鍔(24)に焦点を当てて斜視図と断面図にてわかり易く図示している。
大まかに説明すると、(10−1)(10−2)(10−3)(10−4)は台の前壺、後壺など、一つの壺に鼻緒の鍔(24)を挿げる状況の斜視図であり、(10−5)(10−6)(10−7)(10−8)はその断面図である。(10−9)は鍔(24)が台の裏側に露出したときに、鍔(24)の上に差し込む調整部材(5)を説明する斜視図で、(10−10)(10−11)は調整部材(5)を用いた状況を説明するための断面図である。
まず、(10−1)は鼻緒の鍔(24)を壺に挿入する前の状態で、台に設けられている鍔挿入穴(33)と鍔固定穴(34)の位置関係を説明すると、鍔挿入穴(33)は長形の刳りぬき穴で台の上面から底面に貫通しており、その向きとは90度回転した「十文字」の向きで、台の底面から所定の深さで鍔固定穴(34)が同じく長形で設けられている。その断面図である(10−5)のように、挿げる前のひねった向きの鍔(24)が、長形の細い向きが見えているのと同様に、細い向きが見える鍔挿入穴(33)に対し、鍔固定穴(34)は、底面から所定の深さで長形の長手方向が見える構造となっている。
(10−2)は鍔挿入穴(33)に鼻緒の鍔(24)を挿入して貫通させた状態を示しており、(10−6)のように台の底面より外に、鍔(24)が露出する状態まで鼻緒の端を押し込んだ状態であり、挿げた鍔(24)の向きは細い側が見えている。
(10−3)では鼻緒の首部(25)を手で90度回転させた状況であり、その下に連なる鍔(24)も共に回転している。断面(10−7)のように、鍔(24)は鍔固定穴(34)と同じように長形の長い向きが見える状況になる。
(10−4)では鍔固定穴(34)と鍔(24)が同一の向きになった状態から、鼻緒を引き上げることで鍔(24)を鍔固定穴(34)に収めた状態であり、(10−8)で示すように、鍔固定穴(34)と鍔挿入穴(33)との境目である段差に、鍔(24)が接することで台の上に現れる鼻緒の長さが確定して、鼻緒が台に挿げて固定された状態になる。
In FIG. 10, the details of the procedure for inserting the cord in Example 2 and the adjustment member (5) used in Example 2 will be described with reference to cross-sectional views. Although the method of inserting the cord in Example 2 has already been described with reference to FIG. 9, it is shown in an easy-to-understand manner in perspective and sectional views focusing on one ridge and one ridge (24).
Roughly speaking, (10-1), (10-2), (10-3), and (10-4) are situations in which a cord (24) can be inserted into one heel, such as a forehead or a back heel of a table. (10-5), (10-6), (10-7) and (10-8) are sectional views thereof. (10-9) is a perspective view for explaining the adjusting member (5) to be inserted onto the ridge (24) when the ridge (24) is exposed on the back side of the table. (10-10) (10-11) These are sectional drawings for demonstrating the condition using an adjustment member (5).
First, (10-1) illustrates the positional relationship between the heel insertion hole (33) and the heel fixing hole (34) provided in the base in a state before inserting the chin cord (24) into the heel. The eaves insertion hole (33) is a long, perforated hole that penetrates from the top surface to the bottom surface of the table, and its orientation is the direction of a “cross-shaped” rotated 90 degrees, with a predetermined depth from the bottom surface of the table. The fixing hole (34) is also provided with a long shape. As shown in the cross-sectional view of (10-5), the twisted ridge (24) before insertion can be seen in the narrow direction as well as the long narrow direction. On the other hand, the anchor fixing hole (34) has a structure in which the long longitudinal direction can be seen from the bottom surface at a predetermined depth.
(10-2) shows a state in which the ridge cord (24) is inserted and penetrated into the heel insertion hole (33). As shown in (10-6), the heel (24 ) Is in a state where the end of the umbilical cord is pushed in until it is exposed, and the direction of the inserted collar (24) is visible on the narrow side.
In (10-3), the neck (25) of the umbilical cord is rotated by 90 degrees by hand, and the heel (24) connected underneath is also rotated together. Like the cross-section (10-7), the heel (24) is in a situation where the long and long direction can be seen in the same manner as the heel fixing hole (34).
(10-4) is a state in which the heel (24) is housed in the heel fixing hole (34) by pulling up the nose from the state where the heel fixing hole (34) and the heel (24) are in the same direction, As shown in (10-8), the length of the umbilical cord appearing on the table is determined when the heel (24) is in contact with the level difference between the heel fixing hole (34) and the heel insertion hole (33). Then, the umbilical cord is inserted into the table and fixed.
(10−9)からは実施例2で調整部材を使用する状況を図示しており、斜視図で調整部材を差し込む状況を説明し、(10−10)(10−11)の断面図で調整部材の効果などを説明する。
まず、(10−9)では「コ」の字型の調整部材(5)が準備されている様子を図示したものであり、鍔挿入穴(33)を貫通して台の底面より鍔(24)が露出した状況で、鍔(24)の上にこの調整部材(5)を差し込んで使用するものである。図では「コ」の字型に描くことで、調整部材(5)の中央の空洞部分が鼻緒の首部(25)をまたいで、両側の肉厚が鍔(24)の両側の上に重なることを表しているが、この調整部材(5)の形状は、後に断面図で述べる調整効果を得られるものであれば、この形状に特定するものではなく、例えば首部(25)で隔てた鍔(24)の両側に、2枚の板状の調整部材(5)を差し込んでも同様の調整効果を成すものである。
(10−10)は、鍔固定穴(34)の中で鍔(24)の上に調整部材(5)が2枚差し込まれている様子を断面図で示し、(10−11)では、鍔固定穴(34)の中で鍔(24)の上に調整部材(5)が1枚差し込まれている様子を断面図で示している。
ここで調整部材(5)の厚さを1mmとするならば、(10−10)では、鍔固定穴(34)の中で鍔(24)が固定される位置が1mm+1mmで2mmの厚さほど台の上面から離され深い位置で固定されることになり、おのずと台の上面に現れる鼻緒の長さが2mm短くなる。(10−11)のように調整部材(5)を1枚差し込んだ場合は、鍔(24)は1mm深く固定され、台の上面に現れる鼻緒の長さを1mm短くすることができる。
つまり、実施例2の調整部材(5)の目的、効果は、実施例1の図5の(5−5)(5−6)で示した調整部材(5)と同じ機能を実現するものであり、実施例2においても実施例1と同様、各々の壺で各々の鍔(24)の固定される深さを調整することにより、ユーザの足にフィットする鼻緒になるようユーザ自身が手軽に長さ調節することが可能となる。
From (10-9), the situation in which the adjustment member is used in the second embodiment is illustrated, the situation in which the adjustment member is inserted is explained with a perspective view, and the adjustment is made with the sectional views of (10-10) and (10-11). The effects of the members will be described.
First, (10-9) shows a state in which the “U” -shaped adjusting member (5) is prepared, and passes through the scissors insertion hole (33) from the bottom surface of the base (24). ) Is exposed, the adjustment member (5) is inserted onto the ridge (24) for use. In the figure, the central cavity of the adjustment member (5) straddles the neck (25) of the thong and the wall thickness on both sides overlaps on both sides of the heel (24) by drawing in a “U” shape. However, the shape of the adjustment member (5) is not limited to this shape as long as the adjustment effect described later in the cross-sectional view can be obtained. For example, the collar (25) separated by the neck (25) Even if two plate-like adjustment members (5) are inserted on both sides of 24), the same adjustment effect is achieved.
(10-10) is a cross-sectional view showing that two adjustment members (5) are inserted on the flange (24) in the flange fixing hole (34). A state in which one adjustment member (5) is inserted on the flange (24) in the fixing hole (34) is shown in a sectional view.
Here, if the thickness of the adjusting member (5) is 1 mm, in (10-10), the position at which the collar (24) is fixed in the collar fixing hole (34) is 1 mm + 1 mm and is about 2 mm thick. As a result, the length of the nose that appears on the upper surface of the table is shortened by 2 mm. When one adjustment member (5) is inserted as in (10-11), the heel (24) is fixed 1 mm deep, and the length of the nose appearing on the upper surface of the table can be shortened by 1 mm.
That is, the purpose and effect of the adjustment member (5) of the second embodiment are to realize the same function as the adjustment member (5) shown in FIGS. 5 (5-5) and (5-6) of the first embodiment. Also, in the second embodiment, as in the first embodiment, by adjusting the fixed depth of each heel (24) with each heel, the user himself / herself can easily become a thong that fits the user's foot. The length can be adjusted.
図示していないが、実施例2の場合にも鍔(24)が「へ」の字型に湾曲しないよう、図5で示した補強部材(4)とは形状が異なるが、鍔(24)が首部(25)に対して「T」字型を維持できる補強部材を用意し、鍔(24)の肉厚の上下を囲う構造で湾曲できないよう補強してやれば、鍔(24)は安易に鍔挿入穴(33)へと抜け出ないよう鍔固定穴(34)の中で固定を補強できる。
実施例1では、台(3)の部材として独立気泡発泡スポンジ(EVA)などクッション性も意識した事例として鍔挿入穴(33)や鍔固定穴(34)を丸く開示したが、実施例2では、台(3)は木製などクッション性が少ないまたは無い部材も意識して本願発明の目的を実現する手段である。また、和鼻緒などのように鼻緒(2)の端の部材に柔軟性がなくポリ塩化ビニール(PVC)などの樹脂製より硬い鼻緒(2)の構成も考慮し、実施例1のように鼻緒(2)の鍔(24)だけをひねって挿げられないものであっても、鼻緒(2)の端をひねることで鍔(24)の向きを変えることにより台に鼻緒を挿げることが出来るよう、実施例2は実施例1では実現困難な鼻緒(2)の部材、台(3)の部材において、同様の効果を生む鼻緒付き履物(1)の提案を可能にしている。
Although not shown, the shape of the reinforcing member (4) shown in FIG. 5 is different from that of the reinforcing member (4) shown in FIG. If a reinforcing member that can maintain a “T” shape is prepared with respect to the neck (25) and is reinforced so that it cannot be bent with a structure surrounding the thickness of the collar (24), the collar (24) can be easily Fixation can be reinforced in the heel fixing hole (34) so as not to slip out into the insertion hole (33).
In the first embodiment, the heel insertion hole (33) and the heel fixing hole (34) are disclosed as examples of the base (3) in consideration of cushioning properties such as closed cell foam sponge (EVA). The base (3) is a means for realizing the object of the present invention in consideration of a member having little or no cushioning property such as wooden. Further, considering the configuration of the cord (2) which is not flexible at the end of the cord (2), such as a Japanese cord, and is harder than a resin such as polyvinyl chloride (PVC), the cord as in Example 1 is considered. Even if you can't insert only the ridge (24) of (2), you can insert the ridge into the table by changing the direction of the ridge (24) by twisting the end of the ridge (2) Therefore, the second embodiment makes it possible to propose a footwear (1) with a nose that produces the same effect in the member of the nose (2) and the member of the base (3) that are difficult to realize in the first embodiment.
このように実施例2においても、図8から図10で説明したように、人の素手の力で鼻緒(2)の端をひねって鍔(24)の向きを合わせることで、台(3)の壺の鍔挿入穴(33)へ鼻緒(2)を挿げて、鍔(24)を鍔固定穴(34)に収めることでユーザが簡単に鼻緒(2)を台(3)に挿げて固定することができ、その固定を確実なものにするために補強部材(4)を用いて補強することができ、さらに調整部材(5)を用いることで鼻緒の長さを任意に長節することも可能になるので、ユーザは鼻緒付き履物を履くシチュエーションに合わせて最適な色柄の鼻緒(2)を、最適な色や形状の台(3)に簡単に素手で挿げることが可能であると同時に、鼻緒(2)の長さ調節も自由に行うことが可能になるので、今までの鼻緒付き履物より使い勝手の良い新たな鼻緒き履物を手にすることが可能になる。 Thus, also in Example 2, as explained in FIGS. 8 to 10, the platform (3) is obtained by twisting the end of the nose (2) with the power of a human hand and adjusting the direction of the heel (24). The user can easily insert the cord (2) into the platform (3) by inserting the cord (2) into the rod insertion hole (33) of the kite and placing the kite (24) in the kite fixing hole (34). In order to secure the fixing, the reinforcing member (4) can be used to reinforce, and the adjustment member (5) can be used to arbitrarily increase the length of the cord. Therefore, the user can easily insert the cord (2) with the optimum color pattern into the platform (3) with the optimum color and shape with bare hands according to the situation where the user wears the footwear with the cord. At the same time, it is possible to freely adjust the length of the umbilical cord (2), so it is possible to wear it with a conventional umbilical cord. It is possible to get a more user-friendly new thong-out footwear.
