Description

本考案は、エチレン酢酸ビニル共重合体とエチレンプロピレンゴムを主体とする樹脂を射出成形して、靴底、かかと、甲革、飾帯、羽根、外側カウンター、カフス等靴のパーツ全てを一体的に成形して得られた靴に関する。   The present invention is an injection molding of resin mainly composed of ethylene vinyl acetate copolymer and ethylene propylene rubber, and all shoe parts such as shoe sole, heel, upper, garment, feather, outer counter, cuff, etc. are integrated. It relates to shoes obtained by molding.

従来、予め靴底を成形しておき、この靴底を靴本体の射出成形と同時に一体的ならしめる技術が提案されている(例えば、特許文献1参照)。   Conventionally, a technique has been proposed in which a shoe sole is formed in advance, and this shoe sole is made integral with the injection molding of the shoe main body (for example, see Patent Document 1).

特開昭55−99201号公報JP-A-55-99201

この場合には、靴底を靴本体の射出成形と同時に一工程で一体に成形することができるが、靴底を成形する工程が別途必要であるから、全体的には二工程を必要とする。   In this case, the shoe sole can be integrally formed in one step at the same time as the injection molding of the shoe body. However, since a step for forming the shoe sole is separately required, two steps are generally required. .

そこで、本考案では、その工程をさらに減らして一工程で靴のパーツ全てを一体的に成形することができるようにしたものである。   Therefore, in the present invention, the number of steps is further reduced so that all the shoe parts can be integrally formed in one step.

この目的を達成するために、本考案では、エチレン酢酸ビニル共重合体とエチレンプロピレンゴムを主体とする樹脂を射出成形して、靴底、かかと、甲革、飾帯、羽根、外側カウンター、カフス等靴のパーツ全てを一体的に成形することにより靴を得る。この場合には、一工程という極めて簡単な工程により極めて軽い靴を得ることができる。しかも、パーツ全てが一体的に成形されているので、従来の場合のようにパーツの接合部分や糸による縫合部分から水が侵入することはない。   In order to achieve this purpose, in the present invention, a resin mainly composed of an ethylene vinyl acetate copolymer and ethylene propylene rubber is injection-molded to produce a shoe sole, heel, upper, upper band, feather, outer counter, cuff. The shoe is obtained by integrally molding all the parts of the shoe. In this case, an extremely light shoe can be obtained by an extremely simple process of one process. In addition, since all the parts are integrally formed, water does not enter from the joined part of the parts or the stitched part by the thread as in the conventional case.

靴底、かかとを除く本体側パーツの隣り合う部分が、射出成形による段差として形成されている。この段差も一体成形という極めて簡単な工程により形成され、本体側パーツを互いに繋ぎ合わせた場合と同じような形になる。   Adjacent portions of the body side parts excluding the shoe sole and heel are formed as steps by injection molding. This step is also formed by a very simple process of integral molding, and has the same shape as when the main body side parts are joined together.

射出成形による凹凸状の縫合線が、射出成形による段差に沿って形成されている。この縫合線も一体成形という極めて簡単な工程により形成され、しかも、本体側パーツを互いに繋ぎ合わせた部分に糸に代わる縫合線として形成され、本体側パーツを糸で縫合した場合と同じような形になる。   An uneven suture line formed by injection molding is formed along a step formed by injection molding. This suture line is also formed by a very simple process of integral molding, and it is formed as a suture line instead of thread at the part where the body side parts are joined together, and the shape similar to that when the body side part is sutured with thread become.

請求項1記載の考案によれば、一工程という極めて簡単な工程により極めて軽い靴を得ることができるという効果がある。しかも、従来の場合のようにパーツの接合部分や糸による縫合部分からの水の侵入を完全に防止できる。   According to the first aspect of the invention, there is an effect that an extremely light shoe can be obtained by an extremely simple process of one process. In addition, as in the conventional case, water can be completely prevented from entering from the joined part of the parts and the stitched part by the thread.

請求項2記載の考案によれば、一体成形という極めて簡単な工程により段差を形成することができ、本体側パーツを互いに繋ぎ合わせた場合と同じような形にすることができる効果がある。   According to the second aspect of the present invention, the step can be formed by an extremely simple process of integral molding, and there is an effect that the main body side parts can be formed in the same shape as when they are connected to each other.

請求項3記載の考案によれば、一体成形という極めて簡単な工程により縫合線を形成することができ、本体側パーツを糸で縫合した場合と同じような形にすることができる効果がある。   According to the third aspect of the present invention, the suture line can be formed by an extremely simple process of integral molding, and there is an effect that the main body side part can be formed in the same shape as when sutured with a thread.

本考案に係る靴の一例を、図面を参照しながら詳細に説明する。本考案においては、エチレン酢酸ビニル共重合体とエチレンプロピレンゴムを主体とする樹脂を射出成形して、靴底1、かかと2、甲革3、飾帯4、羽根5、外側カウンター6、カフス7等靴のパーツ全てを一体的に成形することにより靴を得る。この靴を図1に示す。図1(a)はその側面図、図1(b)は中央縦断面図である。なお、図1(b)における図面符号8は、靴の中底部分に接合させた中敷きである。   An example of a shoe according to the present invention will be described in detail with reference to the drawings. In the present invention, a resin mainly composed of an ethylene vinyl acetate copolymer and ethylene propylene rubber is injection-molded to produce a sole 1, a heel 2, an upper 3, an ornament 4, a feather 5, an outer counter 6, and a cuff 7 The shoe is obtained by integrally molding all the parts of the shoe. This shoe is shown in FIG. FIG. 1A is a side view thereof, and FIG. 1B is a central longitudinal sectional view thereof. In FIG. 1 (b), reference numeral 8 is an insole joined to the insole portion of the shoe.

エチレン酢酸ビニル共重合体(EVA)とエチレンプロピレンゴム(EPR)の混合比は、前者を75〜85重量%、後者を15〜25重量%とするのが最適であり、これらを主体とする樹脂に架橋剤と発泡剤とを適量添加することが望ましい。そして、混練調整したこの樹脂混和物を射出成形機に供給して発泡剤の分解温度以下で溶融混練し、この溶融混練樹脂混和物を発泡剤の分解温度以上に加熱した金型に注入する。すると、金型内で前記溶融混練樹脂混和物が成形され、この成形物を金型から開放して発泡膨張させれば、図1に示すような靴を得ることができる。   The mixing ratio of ethylene vinyl acetate copolymer (EVA) and ethylene propylene rubber (EPR) is optimally 75 to 85% by weight for the former and 15 to 25% by weight for the latter. It is desirable to add appropriate amounts of a cross-linking agent and a foaming agent. Then, the kneaded and adjusted resin mixture is supplied to an injection molding machine and melt-kneaded at a temperature below the decomposition temperature of the foaming agent, and the melt-kneaded resin mixture is injected into a mold heated to a temperature above the decomposition temperature of the foaming agent. Then, the melt-kneaded resin admixture is molded in a mold, and if the molded article is released from the mold and expanded by foaming, a shoe as shown in FIG. 1 can be obtained.

なお、靴底1の底面をザラザラした面にしておくと良い。このようにするには、成形用金型のキャビティ面をザラザラにしておけば良い。そうすると、成形物を金型から開放した時、靴底1の底面が自然にザラザラした面になり、履いた場合にも滑りにくい。   Note that the bottom surface of the shoe sole 1 is preferably a rough surface. In order to do this, the cavity surface of the molding die may be made rough. Then, when the molded product is released from the mold, the bottom surface of the shoe sole 1 naturally becomes a rough surface, and even when worn, it is difficult to slip.

この靴は極めて軽く、特に、靴底1、かかと2、甲革3、飾帯4、羽根5、外側カウンター6、カフス7等靴のパーツの隣り合う部分が、射出成形による段差aとして形成されている。この段差も一体成形という極めて簡単な工程により形成され、図1(a)及び図2に示すように、本体側パーツを互いに繋ぎ合わせた場合と同じような形になる。   This shoe is extremely light, and in particular, the adjacent parts of the shoe parts such as the sole 1, heel 2, upper 3, upper belt 4, feather 5, outer counter 6, cuff 7 are formed as a step a by injection molding. ing. This step is also formed by a very simple process of integral molding, and has the same shape as when the main body side parts are connected to each other as shown in FIG. 1 (a) and FIG.

そして、図2に拡大して示すように、射出成形による凹凸状の縫合線bが、射出成形による段差aに沿って形成されている。この縫合線bも一体成形という極めて簡単な工程により形成され、しかも、本体側パーツを互いに繋ぎ合わせた部分に糸に代わる縫合線として形成され、本体側パーツを糸で縫合した場合と同じような形になる。   As shown in FIG. 2 in an enlarged manner, a concavo-convex suture line b formed by injection molding is formed along a step a formed by injection molding. This suture line b is also formed by a very simple process of integral molding, and it is formed as a suture line in place of the thread at the part where the body side parts are joined together, and is similar to the case where the body side part is sutured with a thread. Become a shape.

このように、靴底1、かかと2、甲革3、飾帯4、羽根5、外側カウンター6、カフス7等靴のパーツ全てを一体的に成形することにより得られた靴は、極めて軽く、しかも、従来の場合のようにパーツの接合部分や糸による縫合部分からの水の侵入を完全に防止できる。   Thus, the shoes obtained by integrally molding all the shoe parts such as the sole 1, the heel 2, the upper 3, the decorative band 4, the feather 5, the outer counter 6, the cuff 7 are extremely light, In addition, as in the conventional case, water can be completely prevented from entering from the joined part of the parts and the stitched part by the thread.

したがって、厨房や洗車時等水を扱う際に履けば、また、水を含んでいるゴルフ場において使用するスパイクに適用すると、非常に有利である。また、図面では、本考案を短靴に適用した場合を例示したが、それよりも背の高い形式のブーツや長靴タイプの靴にも充分適用できる。   Therefore, it is very advantageous when worn when handling water such as in a kitchen or car wash, and when applied to spikes used in golf courses containing water. Moreover, although the case where this invention was applied to a short boot was illustrated in drawing, it can fully apply also to a boot of a tall type and a boot boot type than it.
