本考案は靴保形芯材に関し、特に靴底がポリ塩化ビニー
ルである靴に適する靴保形芯材に関する。[Detailed Description of the Invention] The present invention relates to a shoe shape-retaining core material, and more particularly to a shoe shape-retaining core material suitable for shoes whose soles are made of polyvinyl chloride.
靴底がポリ塩化ビニールである靴は、射出成形機のモー
ルドと胛被が被着されたラストを組合わせて形成された
空窩部内に、加熱溶触されたポリ塩化ビニールが注入さ
れ、靴底が成形されると同時に該靴底が胛被下面に接着
されることにより製造されている。Shoes with polyvinyl chloride soles are made by injecting heat-molten polyvinyl chloride into the cavity formed by combining the mold of an injection molding machine and the last covered with a lace. The shoe sole is manufactured by bonding the sole to the underside of the shoe at the same time as the shoe is molded.
このとき、射出成形機から取出された靴は、暫らくの間
、靴底が熱く、漸次室温まで冷却しているが、その間徐
々に靴底が収縮し、ラストに被着されている胛被が所望
立体構造の弾性層となりうるゴム接着剤等による貼り合
せ構造でないことと相俟って、胛被の変形がはなはだし
く、特に履口部が横に広がっていわゆる1笑うヨという
現象を呈しさらに購入者が履用したときに足首に対する
フィツトが悪くなったりし、又胛被前部が偏平になって
靴の立体感が薄れたりし、何れにしても商品価値を低下
させていた。At this time, the sole of the shoe is hot for a while after being taken out of the injection molding machine, and gradually cools down to room temperature. Coupled with the fact that it is not a bonded structure using rubber adhesive, etc., which can serve as an elastic layer with a desired three-dimensional structure, the deformation of the shoe cover is significant, especially at the shoe opening, which spreads laterally, causing a so-called "one-laugh" phenomenon. When worn by a person, the fit around the ankle becomes poor, and the front part of the shoe becomes flat, reducing the three-dimensional feel of the shoe, which in any case reduces the product value.
従来、靴底がポリ塩化ビニールである靴の外観低下を防
ごうとして、厚紙等を利用した芯材が靴内部に挿入され
ていた。Conventionally, in an attempt to prevent the appearance of shoes with polyvinyl chloride soles from deteriorating, a core material made of cardboard or the like has been inserted inside the shoe.
しかし、今まで使用されていた数多くの靴保形芯材は、
切込みが多すぎて直ぐ変形し効果が薄れたり、形状自体
が複雑になり手間がかかりすぎたりして実用に供し難い
欠点があった。However, many shoe shape-retaining core materials that have been used until now,
There were drawbacks such as having too many incisions, causing deformation quickly and reducing the effect, and making the shape itself complicated and requiring too much effort, making it difficult to put it to practical use.
本考案は、今まで使用されていた靴保形芯材が有してい
た上記のような欠点を除去することを目的とするもので
あり、その構成について、第1図〜第7図にて説明する
。The purpose of this invention is to eliminate the above-mentioned drawbacks of shoe shape-retaining core materials used up until now, and the structure is shown in Figures 1 to 7. explain.
先ず、第1図に示すような、台形1と前方後円形2とよ
りなる一体物3であり、該一体物3は前部4と後部5と
に二分する折積線6を有し、さらに該折線6とその中点
7において直交する折線8を有し、該中点7と台形1の
下辺両端9,9との間に折線10.10を有する一体物
3が用意され、次いで第2図〜第7図に示すように、折
線8で下方に全体が折り曲げられ、その際、後部5にお
いては右側面11と左側面12とが接触し、前部4にお
いては折線10゜10が横方向15.15に拡開され四
角鐘状に形成されているものである。First, as shown in FIG. 1, there is an integrated object 3 consisting of a trapezoid 1 and a front and rear circle 2, and the integrated object 3 has a fold line 6 that divides it into a front part 4 and a rear part 5, and further An integral body 3 is prepared which has a fold line 8 orthogonal to the fold line 6 and its midpoint 7, and has a fold line 10 and 10 between the midpoint 7 and both ends 9, 9 of the lower side of the trapezoid 1, and then a second As shown in FIGS. 7 to 7, the entire body is bent downward along the fold line 8, and at this time, the right side surface 11 and the left side surface 12 are in contact with each other in the rear part 5, and the fold line 10°10 is bent horizontally in the front part 4. It is expanded in directions 15 and 15 and formed into a square bell shape.
尚、第1図に示すような一体物3が、折線8で下方に全
体が折り曲げられ、前部4において折線10.10が横
方向15.15に拡開され、四角鐘状に形成されるとき
、折線10,10が折線8と直交するよう拡開された場
合は、第2図〜第4図のようになり、折線10,10の
拡開がやや少なく直交しない場合は第5図〜第7図のよ
うになリ、前者は靴巾が広い場合、後者は狭い場合に適
宜使い分けられる。Incidentally, the integral object 3 as shown in FIG. 1 is entirely bent downward along the folding line 8, and the folding line 10.10 is widened in the lateral direction 15.15 at the front part 4, forming a square bell shape. When the fold lines 10, 10 are expanded to be perpendicular to the fold line 8, the result will be as shown in Figs. 2 to 4, and if the fold lines 10, 10 are expanded slightly and do not intersect at right angles, the result will be as shown in Figs. 5 to 4. As shown in Fig. 7, the former is used when the shoe width is wide, and the latter is used when the shoe width is narrow.
又、接触せられた後部5の右側面11と左側面12は糊
付けして固着してもよいし、ホチキス紙綴器等で固着し
てもよい。Further, the right side surface 11 and the left side surface 12 of the rear portion 5 that are in contact with each other may be fixed with glue, or may be fixed with a stapler or the like.
本考案の靴保形芯材は、第8図及び第9図に示すように
靴16内部に挿入されたとき、中点7及び前部4の折線
8によって胛被前部17が偏平にならない様に下から支
えられ、一方、履口部18の横巾は接触された後部5の
右側面11と左側面12の板状19によって縦方向20
に引張られ、これらの作用が両々相埃って靴16全体が
所望の立体構造に保持され、ケース内で左右の靴が、伝
令、重ねられても変形しない。When the shoe shape-retaining core material of the present invention is inserted into the shoe 16 as shown in FIGS. 8 and 9, the front part 17 of the shoe does not become flat due to the midpoint 7 and the fold line 8 of the front part 4. On the other hand, the width of the shoe opening 18 is extended in the vertical direction 20 by the plates 19 of the right side 11 and left side 12 of the rear part 5 that are in contact with each other.
These actions work together to hold the entire shoe 16 in the desired three-dimensional structure, and it will not deform even if the left and right shoes are stacked on top of each other inside the case.
又、本考案の靴保形芯材は、切込みが全くないため、靴
16内部に挿入中に変形したり破損したりすることはな
く、その上、形状も簡単であるから製造するのに手間が
かからず、良質な靴保形芯材が安価に得られる。In addition, since the shoe shape-retaining core material of the present invention has no incisions, it will not be deformed or damaged while being inserted into the shoe 16, and its shape is simple, so it is easy to manufacture. A high-quality shoe shape-retaining core material can be obtained at a low cost without being expensive.
