Description

【0001】
【産業上の利用分野】
本発明は、通気性がよく足蒸れを軽減する靴底のプッシュプル方式のエア流れ構造に関する。
【0002】
【従来の技術】
従来、靴底の踵部底面に一つの空気吸排ポンプを設け、前記空気吸排ポンプには、吸気管、排気管を付設し、靴内部の臭気を空気吸排ポンプ内へ導入し、且つ蓄積した臭気を外部へ導出排気する靴底構造が提示されている。(例えば、特許文献1参照。)
中敷には換気装置が備えてある。換気装置は荷重の変動によって送気と引気を行う空気ポンプと、靴内部の空気の吸気と、吸気した空気の靴外部への排気とを交互に行う吸排装置とを備えている。空気ポンプは足裏の踵部に対応する位置に設けられており、吸排装置は足の土不踏部に対応する位置に設けられている。吸排装置の前方部には吸気口が足指基部に対応する位置まで延びている吸気管を有し、後方部には空気ポンプと吸排装置とを繋ぐ連絡管と、排気口が靴外部まで延びている排気管とを有する靴底構造が提示されている。(例えば、特許文献2参照。)
エアの出入りが一つのポンプ本体のみで、踏付側の靴内の蒸れた空気を吸引し、踵側の靴外に一方向に排出する構造である。

【発明が解決しようとする課題】
しかしながら、上記靴底では、上記エアタンクから靴内の蒸れた空気を踏付部から空気を吸入し、靴外に出す方法では、靴内の空気が動くだけなので次第に空気の湿度が高くなり足蒸れ軽減効果は少ない。靴内の湿度が高い空気を積極的に外に排出できるが、外気の新鮮な空気を取り入れることはできないので足蒸れ軽減効果はあまり期待できない。
【0005】
本発明は、以上の課題に鑑みてなされたものであり、確実に靴内部の通気性を確保できる靴底の構造を提供することを目的とする。局部排気設備機器の効率的な考えであるプッシュプル方式のエアの流れを作り出し、新鮮な空気が吸入され、且つ靴内の湿気を瞬時に排出する。新鮮な空気と蒸れた空気が一緒になることなく別々の部屋で管理移動されるので蒸れ解消効果が高い。
【0006】
【課題を解決するための手段】
上記課題を解決するために、本発明の靴底の構造は、靴底の熱圧縮成型EVAスポンジ等のミッドソール踵部の略中央部に配設される二つの併置されたエアポンプ本体と、前記エアポンプ本体から靴内の踏付側の略中央部に向けて靴底部に配設される第二エア排出管及び第二エア吸入管と、前記エアポンプ本体から靴底の踵部の外側に向けて配設される第一エア吸入管及び第一エア排出管と、が構成されている靴底において、前記エアポンプ本体と前記エア管との各々の繋ぎ口には各々の逆止弁が設置され、靴内の踵部が加重・抜重されることによって、前記エアポンプ本体の容積が変化し、新鮮な空気が、踵吸気孔を通じて靴底の踵部の外部から通気防水エアフィルター、第一エア吸入管と吸気用逆止弁を通過し第一エアポンプ本体に吸入され、排気用逆止弁と第二エア排出管によって、靴内の長手方向の踵端から全長の75%付近の踏付側の略中央部に送出され、且つ靴内の踏付付近の蒸れた空気は、靴内の長手方向の踵端から全長の60%付近の踏付側の略中央部から第二エア吸入管と吸気用逆止弁を通じて第二エアポンプ本体に吸入され、排気用逆止弁と第一エア排出管を通過し踵排気孔を通じて靴底の踵部の外部に排出され、且つ踵吸気孔と第一エア吸入管との継ぎ目及び踵排気孔と第一エア排出管との継ぎ目から空気が漏れないように、四角形状等の透明合成樹脂シートが熱圧縮成型EVAスポンジ等のミッドソールに密着シールされているプッシュプル方式のエア流れ構造を特徴とする。
【0007】
本発明の靴底の構造は、靴底において、爪先側外面及び内不踏側外面に複数の通気孔を配すると共に、爪先側の通気孔と内不踏側の通気孔とを複数の縦溝で連通し、且つ前記複数の縦溝を靴内の踏付側で相互に横溝で連通して、歩行等の移動によって、前記爪先側外面から通気防水エアフィルターを通じて靴外の新鮮な空気が取り込まれ靴内の踏付側を通過して、前記内不踏側外面から靴内の踏付の蒸れた空気が靴外に排出されるプッシュプル方式のエア流れ構造を特徴とする。
【0008】
本発明の靴底の構造は、靴底において、前記に記載された二つのプッシュプル方式のエア流れ構造を同時に構成されたことを特徴とする。
【0009】
靴内に吸気と排気が同時にできる構造により、湿度が低い外気を取り込み、若干の時間差の後に湿度が高い靴内の空気を排出することができるので、プッシュプル方式のエアの流れを作り出し、長時間履用しても靴内の湿度は低い状態を維持できる。またさらに、爪先側外面及び内不踏側外面に複数の通気孔を配すると、歩行等の移動によって、靴の爪先からも湿度が低い外気を取り込み、靴内の踏付側を通過して、靴の内不踏側外面から靴内の踏付の蒸れた空気が靴外に排出することでさらに足蒸れ軽減効果を促進することができる。
【0010】
【実施の形態】
以下に本発明の実施例について図面に基づいて説明する。
図1は、本実施例の靴底の平面図であり、図2は、本実施例の靴底の踵排気孔付近の断面図である。図3は、本実施例の靴底の踵吸気孔付近を部分的に拡大した断面図である。
本発明の靴底を利用した靴を履いた人が歩行する場合、まず停止しているときは、靴の踵部は加重されいる。踵部が加重されると、靴内の踵部底部の略中央部に配設される二つの併置されたエアポンプ本体1,2が押し潰される。エアポンプ本体1,2の容積は急激に減少する。このとき、エアポンプ本体1,2の内圧は正圧となる為、吸気用逆止弁12は閉弁し排気用逆止弁13は開弁する。従って、エアポンプ本体1,2に蓄積された容積分の空気が外部へ排出されることになる。この結果、第一エアポンプ本体1内の空気は、排気用逆止弁13と第二エア排出管10によって、靴内の長手方向の踵端から全長の75%付近の踏付側の略中央部に一方向へ送出される。一方、第二エアポンプ本体2内の空気は、排気用逆止弁13と第一エア排出管9を通じて靴底の踵部の外部に一方向へ排出される。
【0011】
次いで、その足が振り上げられると、踵部は抜重されると共に踵部が地面から離間する。踵部が抜重されると、エアポンプ本体1,2の復元力により迅速に従前の形状に戻り、二つの併置されたエアポンプ本体1,2が押し潰された形状から元の形状へ回復される。エアポンプ本体1,2の内圧は負圧となる為、吸気用逆止弁12は開弁し排気用逆止弁13は閉弁する。従って、エアポンプ本体1,2には、増加した容積分の空気が外部から吸入され蓄積されることになる。この結果、第一エアポンプ本体1内に、新鮮な空気が、靴底の踵部の外部から通気防水エアフィルター7、第一エア吸入管8と吸気用逆止弁12を通じて一方向へ吸入される。一方、第二エアポンプ本体2内に、靴内の踏付付近の蒸れた空気が、靴内の長手方向の踵端から全長の60%付近踏付側の略中央部から第二エア吸入管11と吸気用逆止弁12を通じて一方向へ吸入される。
【0012】
次に踵部が加重されると、エアポンプ本体1,2が押し潰され、第一エアポンプ本体1内の新鮮な空気が、排気用逆止弁13と第二エア排出管10によって、靴内の長手方向の踵端から全長の75%付近踏付側の略中央部に一方向へ送出される。第二エアポンプ本体2の靴内踏付付近の蒸れた空気が、排気用逆止弁13と第一エア排出管9を通じて靴底の踵部の外部に一方向へ排出される。
【0013】
熱圧縮成型EVAスポンジ等のミッドソールの踵部において、踵吸気孔と第一エア吸入管との継ぎ目及び踵排気孔と第一エア排出管との継ぎ目からは、空気漏れが発生しないように、四角形状等の透明合成樹脂シートが、熱圧縮成型EVAスポンジ等のミッドソールの該継ぎ目上面に、水性系・溶剤系接着剤又はホットメルト接着フィルムで密着シールされている。透明合成樹脂シートの形状は、四角形状に限定される訳でなく、該継ぎ目を被覆する大きさなら円形、三角、台形等の形状でも良い。合成樹脂シートは、透明であると該継ぎ目を被覆する状態が判明するので好適であるが、透明でなくても良い。

【0017】
靴内の踵部が加重・抜重されることによって、前記エアポンプ本体1,2の容積が変化する。新鮮な空気が、靴底の踵部の外部から、踵吸気孔4に配設された有孔金属板14、通気防水エアフィルター7、第一エア吸入管8と吸気用逆止弁12を通じて第一エアポンプ本体1に吸入され、排気用逆止弁13と第二エア排出管10によって、靴内の長手方向の踵端から全長の75%付近の踏付側の略中央部に送出される。且つ靴内の踏付付近の蒸れた空気は、靴内の長手方向の踵端から全長の60%付近の踏付側の略中央部から第二エア吸入管11と吸気用逆止弁12を通じて第二エアポンプ本体2に吸入され、排気用逆止弁13と第一エア排出管9と踵排気孔5に配設された有孔金属板14を通じて靴底の踵部の外部に排出される。
【0018】
踵吸気孔と第一エア吸入管との継ぎ目及び踵排気孔と第一エア排出管との継ぎ目のミッドソール上面に、角を丸くした厚み0.3mm、一辺長さ30mmの四角形状のポリ塩化ビニル製透明合成樹脂シートが、溶剤ウレタン糊で密着シールされている。該継ぎ目からの空気漏れが発生せずに効率的に通気性の空気循環が行われている。透明合成樹脂シートの材質は、ポリアミド樹脂である柔軟性ナイロン、TPU樹脂、ポリ塩化ビニル等である。
【0019】
外部と接触する吸気の通気孔部分の表面には泥やほこりを入りにくくするように網目付きの通気鳩目や有孔金属板14等を設置し、その内側には通気性が良く、防水性のあるポリプロピレンやポリエチレンやEVA等で焼結成型した通気防水エアフィルター7(商品名:フィルタレン・化研(株)厚み2.0mm)を挿入し、第一エアポンプ本体1と通気防水エアフィルター7とがTPU等の樹脂製のホースである第一エア吸入管8で連結されている。通気防水エアフィルター7は、透湿防水性を有するフィルムでも良い。

[Industrial applications]
The present invention relates to a push-pull type air flow structure of a shoe sole which has good air permeability and reduces foot stuffiness.
[0002]
[Prior art]
Conventionally, one air intake / exhaust pump is provided on the bottom surface of the heel portion of the shoe sole, and the air intake / exhaust pump is provided with an intake pipe and an exhaust pipe to introduce the odor inside the shoe into the air intake / exhaust pump and to accumulate the odor. There is proposed a shoe sole structure for guiding and exhausting the outside to the outside. (For example, refer to Patent Document 1.)
The insole is equipped with a ventilation system. The ventilator is provided with an air pump that performs air supply and air suction according to a change in load, and an air intake and exhaust device that alternately performs intake of air inside the shoe and exhaust of the intake air to the outside of the shoe. The air pump is provided at a position corresponding to the heel portion of the sole, and the suction / discharge device is provided at a position corresponding to the soil non-step portion of the foot. At the front of the suction / discharge device, there is an intake pipe whose intake port extends to the position corresponding to the base of the toe, and at the rear, a connecting pipe that connects the air pump and the suction / discharge device, and the exhaust port extends to the outside of the shoe. A sole structure having a closed exhaust pipe is presented. (For example, see Patent Document 2.)

[0004]
[Problems to be solved by the invention]
However, in the above-mentioned shoe sole, in the method in which the humid air in the shoes is sucked in from the air tank from the tread portion and is taken out of the shoes, the air in the shoes only moves, so the humidity of the air gradually increases and the feet become stuffy. The reduction effect is small. Although the air with high humidity inside the shoes can be positively discharged to the outside, the effect of reducing foot stuffiness cannot be expected much because fresh air of the outside air cannot be taken in.
[0005]
The present invention has been made in view of the above problems, and an object of the present invention is to provide a structure of a shoe sole that can reliably ensure air permeability inside a shoe. It creates a push-pull air flow, which is an efficient idea of local exhaust equipment, so that fresh air is inhaled and moisture in the shoes is instantly discharged. Fresh air and humid air are managed and moved in separate rooms without being combined, so that the effect of eliminating humidity is high.
[0006]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, the sole structure of the present invention comprises two side-by-side air pump bodies disposed substantially at the center of a heel portion of a midsole such as a hot-compression molded EVA sponge of the sole, A second air discharge pipe and a second air suction pipe arranged on the sole of the shoe from the air pump body to a substantially central portion on the tread side in the shoe, and from the air pump body to the outside of the heel of the shoe sole. In the sole where the first air suction pipe and the first air discharge pipe are provided, each check valve is installed at a connection port between the air pump body and the air pipe, The weight of the heel portion in the shoe is increased and decreased, so that the volume of the air pump body changes, and fresh air is ventilated from outside the heel portion of the shoe sole through the heel intake hole, a waterproof air filter, a first air suction pipe. Through the check valve for air intake and into the main body of the first air pump It is sent out from the longitudinal heel end in the shoe to the substantially central portion on the tread side near 75% of the total length by the exhaust check valve and the second air discharge pipe, and the stuffiness in the shoe near the tread side. The sucked air is sucked into the main body of the second air pump through the second air suction pipe and the check valve for suction from the substantially central portion on the tread side near 60% of the entire length from the heel end in the longitudinal direction in the shoe, It passes through the stop valve and the first air discharge pipe, is discharged to the outside of the heel portion of the shoe sole through the heel exhaust hole, and a joint between the heel intake hole and the first air intake pipe and the heel exhaust hole, the first air discharge pipe, and the like. In order to prevent air from leaking from the seam, a transparent synthetic resin sheet having a square shape or the like is characterized by a push-pull air flow structure in which it is tightly sealed to a midsole such as a hot-compression molded EVA sponge.
[0007]
The structure of the sole of the present invention has a plurality of ventilation holes on the toe side outer surface and the inner non-stepping side outer surface of the shoe sole, and the toe side ventilation hole and the inner stepping side ventilation hole have a plurality of vertical positions. The grooves communicate with each other, and the plurality of vertical grooves communicate with each other on the tread side in the shoe through lateral grooves. By movement such as walking, fresh air outside the shoe passes from the toe side outer surface through the ventilated waterproof air filter. It is characterized by a push-pull type air flow structure in which the humid air of the tread in the shoe is taken in from the tread side in the shoe and passed through the tread side in the shoe, and the stepped air in the shoe is discharged out of the shoe.
[0008]
The sole structure of the present invention is characterized in that the two push-pull air flow structures described above are simultaneously formed on the sole.
[0009]
With a structure that allows simultaneous intake and exhaust into the shoe, it is possible to take in low-humidity outside air and, after a slight time lag, to exhaust air in the shoe with high humidity, creating a push-pull air flow, Even when worn for a long time, the humidity in the shoe can be kept low. Furthermore, when a plurality of ventilation holes are arranged on the toe side outer surface and the inner non-stepping side outer surface, by movement such as walking, it takes in low humidity outside air from the toe of the shoe and passes through the tread side in the shoe, The stuffy air of the tread in the shoe is discharged from the inner non-stepping side outer surface of the shoe to the outside of the shoe, so that the effect of reducing foot stuffiness can be further promoted.
[0010]
Embodiment
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a plan view of the shoe sole of the present embodiment, and FIG. 2 is a cross-sectional view of the vicinity of the heel exhaust hole of the shoe sole of the present embodiment. FIG. 3 is a cross-sectional view in which the vicinity of the heel intake hole of the shoe sole of the present embodiment is partially enlarged.
When a person wearing shoes using the shoe sole of the present invention walks, first, when the person is stopped, the heel of the shoe is weighted. When the heel is weighted, the two juxtaposed air pump bodies 1 and 2 disposed substantially at the center of the heel bottom in the shoe are crushed. The volumes of the air pump bodies 1 and 2 decrease rapidly. At this time, since the internal pressure of the air pump main bodies 1 and 2 becomes positive pressure, the check valve 12 for intake is closed and the check valve 13 for exhaust is opened. Therefore, the air corresponding to the volume accumulated in the air pump bodies 1 and 2 is discharged to the outside. As a result, the air in the first air pump main body 1 is evacuated by the exhaust check valve 13 and the second air discharge pipe 10 to a substantially central portion on the tread side near 75% of the entire length from the heel end in the shoe in the longitudinal direction. Is sent in one direction. On the other hand, the air in the second air pump body 2 is discharged in one direction to the outside of the heel portion of the shoe sole through the exhaust check valve 13 and the first air discharge pipe 9.
[0011]
Then, when the foot is swung up, the heel is removed and the heel separates from the ground. When the heel is unloaded, the air pump bodies 1 and 2 quickly return to the previous shape due to the restoring force, and the two juxtaposed air pump bodies 1 and 2 are restored from the crushed shape to the original shape. Since the internal pressure of the air pump main bodies 1 and 2 becomes negative pressure, the check valve 12 for intake is opened and the check valve 13 for exhaust is closed. Therefore, the increased volume of air is sucked in from the outside and accumulated in the air pump bodies 1 and 2. As a result, fresh air is sucked into the first air pump main body 1 in one direction from the outside of the heel portion of the shoe sole through the ventilation waterproof air filter 7, the first air suction pipe 8, and the check valve 12 for suction. . On the other hand, in the second air pump main body 2, the humid air near the stepping in the shoe is substantially 60% of the total length from the heel end in the shoe to the second air suction pipe 11 from the substantially central portion on the stepping side. And the air is sucked in one direction through the intake check valve 12.
[0012]
Next, when the heel portion is weighted, the air pump bodies 1 and 2 are crushed, and fresh air in the first air pump body 1 is released by the exhaust check valve 13 and the second air discharge pipe 10 into the shoe. It is sent in one direction from the heel end in the longitudinal direction to approximately the center of the tread side near 75% of the entire length. The humid air near the inside of the shoe of the second air pump body 2 is discharged in one direction to the outside of the heel of the shoe sole through the exhaust check valve 13 and the first air discharge pipe 9.
[0013]
In the heel portion of the midsole such as a hot-compression molded EVA sponge, from the seam between the heel intake hole and the first air suction pipe and from the seam between the heel exhaust hole and the first air discharge pipe, air leakage does not occur. A transparent synthetic resin sheet having a rectangular shape or the like is tightly sealed on the upper surface of the joint of a midsole such as a hot-compression molded EVA sponge with an aqueous / solvent-based adhesive or a hot melt adhesive film. The shape of the transparent synthetic resin sheet is not limited to a square shape, and may be a shape such as a circle, a triangle, or a trapezoid as long as it covers the joint. It is preferable that the synthetic resin sheet is transparent because the state of covering the seam is known, but the synthetic resin sheet need not be transparent.
[0014]
【Example】
Two juxtaposed air pump bodies 1 and 2 are arranged at substantially the center of the bottom of the heel of the shoe. An EVA sponge frame having a thickness of about 2 mm and a width of about 3 mm is fitted around all the two juxtaposed air pump bodies 1 and 2 in order to reduce the noise caused by the operation of the air pump bodies 1 and 2 during walking. ing.
