Description

【0001】
【発明の属する技術分野】
本発明は、所定の強度を有する先芯を爪先部に装着し、着用者の爪先を圧迫や衝撃から防護する安全靴に関するものである。
【0002】
【従来の技術】
従来、安全靴の爪先部には着用者の爪先を保護するための先芯が装入されている。しかしながら、先芯の後端部と甲革の間に段差が生ずることにより、甲革が凹んで外観を損ねたり、先芯の後縁による足当りを悪くしたりすることが多い。この対策として、先芯の後部に先芯補強テープが装着されることがある。
【0003】
例えば、図7の分解斜視図、図8の組立断面図に示すように、先芯1にはアーチ部1aと下辺折曲部1bとが設けられ、先芯補強テープ2には甲革の内面に当接する本体部2aと、本体部2aから前方に延在され先芯2の内面に当接するフランジ部2bとが設けられている。そして、例えば安全靴の表底が発砲ポリウレタン材料のダイレクト式で成形される際には、甲革が靴型に被された状態で甲革の周辺が中底に釣り込まれ、その後に成形機に装着されて発砲ポリウレタン材料が表底用の金型内に射出される。
【0004】
【発明が解決しようとする課題】
しかしながら、上述した従来例には次のような問題点がある。
(a) 甲革は歩行時に55度ほど屈曲されるため、甲革が先芯補強テープ2を足甲に押圧し、段差を大きくすると共に足当りを悪くする。
【0005】
(b) 先芯補強テープ2は前後方向に幅を有するため、その後縁が足甲を強く押圧して足当りを悪くする。
【0006】
(c) 先芯補強テープ2の本体部2aの周方向の長さが短い場合には、靴型に釣り込まれた際に甲革の周辺に変形が生じ、例えば表底が発泡ポリウレタン材料のダイレクト式で成形される際に、発泡ポリウレタン材料の流れが阻害されることがある。
【0007】
(d) 先芯補強テープ2は裁断のし易さから直線的なものを使用しているため、本体部2aをアーチ状に折曲した際に先芯後端の形状と一致せず、本体部2aの前縁が先芯1の後縁に密着し難くなり、また段差を生じている。
【0008】
(e) 先芯1は後方に向かって拡がる形状であるので、先芯補強テープ2を先芯1に装着する際に、フランジ部2bの前縁が狭まると共に本体部2aの後縁が拡がる。このため、フランジ部2bが重なり合って足当りを悪くしたり、靴型に釣り込まれた際に本体部2aが更に拡がるように引き伸ばされ、先芯補強テープ2が先芯1から剥離したりする。
【0009】
本発明の目的は、上述した問題点を解消し、外観品質を向上し足当りを改良した安全靴を提供することにある。
【0010】
【課題を解決するための手段】
上記目的を達成するための本発明に係る安全靴は、爪先を保護するための先芯を甲革の内部に設け、前記先芯の後部に先芯補強テープを装着し、該先芯補強テープは前記甲革の内面に当接する本体部と該本体部から前方に延在し前記先芯の内面に当接するフランジ部とを設けた安全靴において、前記先芯の後縁に接する前記先芯補強テープの天壁の前縁を前記後縁よりも稍々高くして段差を設けると共に、前記天壁を後方に向けて傾斜させたことを特徴とする。
【0011】
【発明の実施の形態】
本発明を図1〜図6に図示の実施例に基づいて詳細に説明する。
図1は実施例の爪先部の断面図であり、甲革11の内側には着用者の爪先を保護するための先芯12と、甲革11と先芯12の間の段差を解消するための先芯補強テープ13とが装着され、これらの甲革11、先芯12及び先芯補強テープ13の内側には先裏14が設けられている。そして、甲革11、先芯12、先芯補強テープ13及び先裏14の周辺は中底15の下部に釣り込まれ、中底15の下面に表底16が、例えば発砲ポリウレタン材料のダイレクト式により成形されている。
【0012】
先芯12は例えば金属材料又は合成樹脂材料により1〜3mmの厚さに形成され、所定の強度が与えられている。図2の縦断面図に示すように、先芯12には甲革11の内面に当接するアーチ部12aを有すると共に、このアーチ部12aの下辺には中底15の下側に釣り込まれる下辺折曲部12bが設けられている。また、先芯補強テープ13は例えばゴム、布、革、合成樹脂等により形成され、先芯12の後方に位置し甲革11に接合する本体部21と、この本体部21から前方に延在され先芯12の内面に接合するフランジ部22とが一体に設けられている。
【0013】
ここで、図3の部分拡大図に示すように、先芯補強テープ13の本体部21の天壁21aの厚さは、先芯12のアーチ部12aの後縁よりも段差dだけ厚くされている。この段差dは先芯12と靴型の加工精度から最大で約0.5mmとされ、安全靴のサイズに応じて最小で約0.1mmとすることが好ましい。また、本体部21の天壁21aは後方へ向かって高く傾斜され、天壁21aの内面は10〜20度の傾斜角θを有する傾斜面とされている。
【0014】
図4の展開図に示すように、先芯補強テープ13の本体部21の前後方向の幅Wは約15mm以下とされると共に、本体部21の後縁には前方へ緩やかに弯曲する弯曲部23が、天壁21aと側壁21b、21cの連接部の近傍から天壁21aにかけて切込まれている。この弯曲部23の曲率半径は例えば90mm程度とされ、天壁21aの略中央部において最も前方へ弯出されている。また、本体部21の側壁21b、21cの周方向の長さは、フランジ部22の側壁22b、22cの周方向の長さよりも距離Lだけ両側でそれぞれ大きくされている。この距離Lは図5の縦断面図、図6の横断面図に示すように、先芯12と先芯補強テープ13を平面Pの上に置いたとき、本体部21の側壁21b、21cの下端が平面Pに接触する大きさとされている。
【0015】
更に、本体部21の前縁は後方へ向かって緩い曲率で円弧状に弯曲する弯曲面24とされ、先芯補強テープ13がアーチ状に折曲された際に、弯曲面24が先芯12の後縁に密着するようにされている。また、本体部21には後縁から前方へ向かう例えば2〜3本のスリット25が、天壁21aと側壁21b、21cの連接部の近傍に設けられていると共に、フランジ部22の前縁には、開口が広くされた三角状の切欠き26がスリット25に対応するように設けられている。
【0016】
本実施例に係る安全靴は上述したように構成されているので、次のような作用効果を得ることができる。
【0017】
(1) 先芯補強テープ13の本体部21の天壁21aを、先芯12の後縁よりも段差dだけ厚くしたので、先芯12の後端部と靴型の形状が完全に一致しない場合でも、装着後に段落ちを防止することが可能となる。
【0018】
(2) 先芯補強テープ13の本体部21の天壁21aを傾斜角θで後方が高くなるように傾斜させたので、甲革11、先芯12、先芯補強テープ13及び先裏14を中底15に釣り込み、その後に靴型を抜いた際に、本体部21の天壁21aの復元力によって甲革11に凹みが発生することを防止できる。
【0019】
(3) 先芯補強テープ13の本体部21の幅Wを約15mm以下としたので、歩行時に甲革11が先芯補強テープ13を押圧することを低減でき、足当りを改善できる。
【0020】
(4) 先芯補強テープ13の本体部21の天壁21aの後縁に弯曲部23を設けたので、先芯補強テープ13が足甲に当接する範囲を狭くでき、足甲に加わる押圧力を更に低減できる。
【0021】
(5) 先芯補強テープ13の本体部21の側壁21b、21cの周方向をフランジ部22の側壁22b、22cの周方向よりも距離Lだけ長くしたので、甲革11を靴型に装着して中底15に釣り込んだ際に、甲革11の周辺が変形することを防止できる。従って、表底16を例えば発泡ポリウレタン材料のダイレクト式で成形する際に、発泡ポリウレタン材料を円滑に流通させることが可能となる。
【0022】
(6) 先芯補強テープ13の展開した本体部21の前縁を緩やかな円孤状の弯曲面24として形成し、装着した際に弯曲面24の全体が先芯12の後縁に密着するようにしたので、段差や剥離の発生を防止できる。
【0023】
(7) 先芯補強テープ13の本体部21の後縁にスリット25を設け、フランジ部22の前縁に切欠き26を設けたので、装着する際に切欠き26が狭まりスリット25が拡がることにより、先芯補強テープ13を先芯12に容易に装着できる。また、甲革11、先芯12、先芯補強テープ13及び先裏14が中底15に釣り込まれた際に、本体部21が引き伸ばされても、スリット25が拡開して先芯補強テープ13が甲革11や先芯12から剥離することを防止できる。
【0024】
【発明の効果】
以上説明したように本発明に係る安全靴は、先芯補強テープの本体部天壁の前縁を先芯の後縁よりも稍々高くして段差を設け、かつ天壁を後方へ向かって高くなるように傾斜させたので、先芯と靴型の加工精度による先芯と靴型の間の隙間を無くすことができ、かつ足当りを改善することが可能となると共に、本体部の上壁の復元力の向上を図り、甲革の落ち込みを防止して外観品質の向上を実現できる。

BACKGROUND OF THE INVENTION
The present invention relates to a safety shoe in which a tip having a predetermined strength is attached to a toe portion to protect the wearer's toe from pressure and impact.
[0002]
[Prior art]
Conventionally, a toe portion for protecting a toe of a wearer is inserted in a toe portion of a safety shoe. However, when a step is formed between the rear end portion of the front core and the upper, the upper is often recessed to deteriorate the appearance, or the foot contact by the rear edge of the front core is often deteriorated. As a countermeasure, a tip reinforcing tape may be attached to the rear portion of the tip.
[0003]
For example, as shown in the exploded perspective view of FIG. 7 and the assembly cross-sectional view of FIG. 8, the tip 1 has an arch portion 1a and a lower bent portion 1b, and the tip reinforcing tape 2 has an inner surface of the upper. And a flange portion 2b that extends forward from the main body portion 2a and contacts the inner surface of the tip 2 is provided. And, for example, when the outsole of safety shoes is molded with a direct polyurethane foam material, the area around the upper is caught in the insole while the upper is covered with the shoe mold, and then the molding machine The foamed polyurethane material is injected into the mold for the bottom surface.
[0004]
[Problems to be solved by the invention]
However, the conventional example described above has the following problems.
(a) Since the upper part is bent by about 55 degrees during walking, the upper part presses the lead-core reinforcing tape 2 against the instep, increasing the level difference and worsening the foot contact.
[0005]
(b) Since the lead-core reinforcing tape 2 has a width in the front-rear direction, the rear edge strongly presses the instep and makes the foot contact worse.
[0006]
(c) When the length in the circumferential direction of the main body 2a of the lead-core reinforcing tape 2 is short, deformation occurs in the periphery of the upper when it is caught in a shoe mold. When the molding is performed directly, the flow of the polyurethane foam material may be hindered.
[0007]
(d) Since the front-end reinforcing tape 2 is linear for ease of cutting, it does not match the shape of the rear end of the front-end when the main body 2a is bent into an arch shape. It becomes difficult for the front edge of the portion 2a to be in close contact with the rear edge of the lead core 1, and a step is generated.
[0008]
(e) Since the front core 1 has a shape that expands toward the rear, when the front core reinforcing tape 2 is attached to the front core 1, the front edge of the flange portion 2b is narrowed and the rear edge of the main body portion 2a is expanded. For this reason, the flange part 2b overlaps, and a foot contact is worsened, or when the body part 2a is stretched so that it may further expand when it is caught in a shoe type, the tip core reinforcing tape 2 peels from the tip core 1. .
[0009]
An object of the present invention is to provide a safety shoe that solves the above-described problems, improves the appearance quality, and improves the foot contact.
[0010]
[Means for Solving the Problems]
In order to achieve the above object, a safety shoe according to the present invention is provided with a tip for protecting a toe inside the upper, and a tip reinforcing tape is attached to the rear portion of the tip, the tip reinforcing tape. Is a safety shoe provided with a main body portion that contacts the inner surface of the upper and a flange portion that extends forward from the main body portion and contacts the inner surface of the front core. The top edge of the top wall of the reinforcing tape is often made higher than the rear edge to provide a step, and the top wall is inclined rearward.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
The present invention will be described in detail based on the embodiment shown in FIGS.
FIG. 1 is a cross-sectional view of the toe portion of the embodiment, in which the tip 11 for protecting the toe of the wearer and the step between the upper 11 and the tip 12 are eliminated inside the upper 11. The tip back reinforcing tape 13 is attached, and the front and back 14 are provided inside the upper 11, the tip 12 and the tip reinforcing tape 13. Then, the periphery of the upper 11, the tip 12, the tip reinforcing tape 13 and the tip back 14 is caught in the lower part of the midsole 15, and the bottom 16 is formed on the lower surface of the midsole 15, for example, a direct type of foamed polyurethane material. It is molded by.
[0012]
The tip 12 is formed to a thickness of 1 to 3 mm, for example, from a metal material or a synthetic resin material, and is given a predetermined strength. As shown in the longitudinal cross-sectional view of FIG. 2, the tip 12 has an arch portion 12 a that abuts the inner surface of the upper 11, and the lower side of the arch portion 12 a is fed to the lower side of the midsole 15. A bent portion 12b is provided. The lead core reinforcing tape 13 is formed of, for example, rubber, cloth, leather, synthetic resin, or the like. The main body portion 21 is located behind the tip core 12 and joined to the upper 11 and extends forward from the main body portion 21. The flange portion 22 that is joined to the inner surface of the tip 12 is integrally provided.
[0013]
Here, as shown in the partially enlarged view of FIG. 3, the thickness of the top wall 21 a of the main body portion 21 of the lead-core reinforcing tape 13 is made thicker than the rear edge of the arch portion 12 a of the lead-core 12 by a step d. Yes. The level difference d is about 0.5 mm at the maximum from the processing accuracy of the tip 12 and the shoe mold, and preferably about 0.1 mm at the minimum according to the size of the safety shoe. Moreover, the top wall 21a of the main body 21 is highly inclined toward the rear, and the inner surface of the top wall 21a is an inclined surface having an inclination angle θ of 10 to 20 degrees.
[0014]
As shown in the developed view of FIG. 4, the width W in the front-rear direction of the main body 21 of the lead-core reinforcing tape 13 is about 15 mm or less, and a bent portion that gently curves forward at the rear edge of the main body 21. 23 is cut from the vicinity of the connecting portion of the top wall 21a and the side walls 21b and 21c to the top wall 21a. The radius of curvature of the bent portion 23 is, for example, about 90 mm, and is bent forward most in the substantially central portion of the top wall 21a. Further, the circumferential lengths of the side walls 21b and 21c of the main body 21 are made larger on both sides by a distance L than the circumferential lengths of the side walls 22b and 22c of the flange portion 22, respectively. As shown in the longitudinal sectional view of FIG. 5 and the transverse sectional view of FIG. 6, this distance L is obtained when the tip 12 and the tip reinforcing tape 13 are placed on the plane P, and the distance between the side walls 21 b and 21 c of the main body 21. The lower end is sized to contact the plane P.
[0015]
Further, the front edge of the main body portion 21 is a curved surface 24 that is bent in an arc shape with a gentle curvature toward the rear, and when the leading-core reinforcing tape 13 is bent in an arch shape, the curved surface 24 is bent into the leading-edge 12. It is made to adhere to the rear edge. In addition, the main body portion 21 is provided with, for example, two to three slits 25 extending forward from the rear edge in the vicinity of the connecting portion between the top wall 21a and the side walls 21b and 21c, and at the front edge of the flange portion 22. The triangular notch 26 having a wide opening is provided so as to correspond to the slit 25.
[0016]
Since the safety shoes according to the present embodiment are configured as described above, the following operational effects can be obtained.
[0017]
(1) Since the top wall 21a of the main body portion 21 of the front core reinforcing tape 13 is thicker than the rear edge of the front core 12 by a level difference d, the rear end portion of the front core 12 and the shoe shape do not completely match. Even in this case, it is possible to prevent the step-down after the mounting.
[0018]
(2) Since the top wall 21a of the main body portion 21 of the toe-core reinforcing tape 13 is inclined so that the rear becomes higher at the inclination angle θ, the upper 11, the torsion 12, the toe-core reinforcing tape 13 and the front and back 14 are attached. It is possible to prevent the upper 11 from being recessed due to the restoring force of the top wall 21a of the main body 21 when the shoe is pulled out into the insole 15 and then the shoe is pulled out.
[0019]
(3) Since the width W of the main body portion 21 of the front-core reinforcing tape 13 is about 15 mm or less, it is possible to reduce the upper 11 from pressing the front-core reinforcing tape 13 during walking, and to improve the foot contact.
[0020]
(4) Since the curved portion 23 is provided at the rear edge of the top wall 21a of the main body portion 21 of the toe core reinforcing tape 13, the range in which the toe core reinforcing tape 13 contacts the instep can be narrowed, and the pressing force applied to the instep Can be further reduced.
[0021]
(5) Since the circumferential direction of the side walls 21b and 21c of the main body portion 21 of the lead-core reinforcing tape 13 is made longer by the distance L than the circumferential direction of the side walls 22b and 22c of the flange portion 22, the upper 11 is attached to the shoe mold. Thus, it is possible to prevent the periphery of the upper 11 from being deformed when it is caught in the insole 15. Therefore, when the front bottom 16 is formed by, for example, a direct polyurethane foam material, the polyurethane foam material can be smoothly distributed.
[0022]
(6) The front edge of the main body portion 21 where the tip-core reinforcing tape 13 is developed is formed as a gently rounded arcuate curved surface 24, and the entire curved surface 24 comes into close contact with the rear edge of the tip core 12 when mounted. Since it did in this way, generation | occurrence | production of a level | step difference and peeling can be prevented.
[0023]
(7) Since the slit 25 is provided at the rear edge of the main body 21 of the lead-core reinforcing tape 13 and the notch 26 is provided at the front edge of the flange 22, the notch 26 is narrowed and the slit 25 is widened when attached. Thus, the tip reinforcing tape 13 can be easily attached to the tip 12. In addition, when the upper 11, the tip 12, the tip reinforcing tape 13 and the tip 14 are fitted into the insole 15, even if the main body 21 is stretched, the slit 25 is expanded and the tip is reinforced. It is possible to prevent the tape 13 from peeling from the upper 11 and the tip 12.
[0024]
【The invention's effect】
As described above, the safety shoe according to the present invention is provided with a step by making the front edge of the top wall of the main body portion of the lead core reinforcing tape higher than the rear edge of the tip core, and the ceiling wall toward the rear. Since it is tilted so as to be higher, it is possible to eliminate the gap between the tip and the shoe due to the processing accuracy of the tip and the shoe, and it is possible to improve the foot contact and By improving the resilience of the wall, it is possible to improve the appearance quality by preventing the upper from falling.
