Description
本考案は、靴の踵の型崩れを防止するための靴の踵の保型具に関する。 The present invention relates to a shoe heel retaining device for preventing the heel of the shoe from losing its shape.
従来から、靴の踵を保型するために、靴の踵の中にカウンター（月型芯）が装着されている。使用者が靴を履くときは、靴の踵を痛めないように、手や靴べらを利用するのが一般的である。また、このカウンター（月型芯）は、通常、使用者が誤って足の踵でカウンターの上縁部を踏み折るのを防止するため、靴の踵の下部までの高さとしている。しかし、使用者は往々にして、横着し、手や靴べらを使用しないで靴の踵を踏んで足を無理やり靴の内部に入れることがある。このため、カウンター（月型芯）が変形して、靴の踵は元の状態を保てなくなり、歩行しづらく、また見た目も悪くなる。靴の踵のカウンター（月型芯）が、一旦型崩れを起こし変形してしまうと、元の状態に戻らないので、専門の修理屋さんに依頼して、カウンター（月型芯）を取り換えてもらう必要がある。 Conventionally, a counter (moon-shaped core) has been installed inside the heel of a shoe in order to maintain the shape of the heel of the shoe. When putting on shoes, users generally use their hands or a shoehorn to avoid damaging the heels of the shoes. Further, this counter (moon-shaped core) is usually set to a height that reaches the bottom of the heel of the shoe to prevent the user from accidentally stepping on the upper edge of the counter with the heel of the foot. However, users often lie down and force their foot into the shoe by stepping on the heel of the shoe without using their hands or a shoe horn. As a result, the counter (moon-shaped core) becomes deformed and the heel of the shoe no longer maintains its original state, making it difficult to walk and making the shoe look bad. Once the heel counter (moon-shaped core) of the shoe loses its shape and becomes deformed, it will not return to its original state, so ask a professional repair shop to replace the counter (moon-shaped core). I need to get it.
そこで、例えば、特許文献１では、硬質の材料でカウンター（月型芯）の上縁部に反り返し部を設け、使用者の足の踵裏がカウンター（月型芯）の上縁部を踏みつけないでスムーズに靴を履くことが可能な靴が提案されている。また、特許文献２では、靴の踵部や、靴べら自体が潰れないように、折曲部などのない硬質材料で形成された靴べらを靴の踵の内面に接着剤などにより取り付けることが提案されている。さらに、特許文献３では、手を使わずに靴が履けるように、靴の踵部の上縁部端に、上方斜め後方に向けて延びる硬質の突片部を形成し、上方から降ろされる使用者の足の踵を突片部が靴内部に確実に案内することができる靴が提案されている。 For example, in Patent Document 1, a curved part is provided on the upper edge of the counter (moon-shaped core) using a hard material, so that the sole of the heel of the user's foot steps on the upper edge of the counter (moon-shaped core). Shoes that can be smoothly put on without having to wear shoes have been proposed. Furthermore, Patent Document 2 proposes attaching a shoehorn made of a hard material with no bent parts to the inner surface of the heel of the shoe using an adhesive or the like to prevent the heel of the shoe or the shoehorn itself from being crushed. ing. Furthermore, in Patent Document 3, a hard projecting piece is formed at the upper edge of the heel of the shoe and extends diagonally upward and rearward so that the shoe can be put on without using hands. Shoes have been proposed in which a protrusion can reliably guide the heel of a person's foot into the shoe.
しかし、これらの方法では、靴の踵を硬質材料で補強して、靴の踵を必要以上に硬くすることになり、使用者の足の踵を痛めたり、フィット感を損ねるなどの問題があった。本考案者はこれらの問題を解決するため、鋭意検討を進めた結果、超弾性合金の驚異的な弾性回復性を利用することで、これらの問題を解決しようと試み本考案に至った。 However, with these methods, the heel of the shoe is reinforced with a hard material, making the heel of the shoe unnecessarily hard, which poses problems such as hurting the heel of the user's foot and impairing the fit. Ta. In order to solve these problems, the inventor of the present invention has carried out intensive studies, and as a result, he has attempted to solve these problems by utilizing the amazing elastic recovery properties of superelastic alloys, and has arrived at the present invention.
請求項１の考案は、靴の踵の保型具であって、靴の踵部の上部に配置する踵保型部材と、靴の甲材の下部に配置する2つの足部材と、踵保型部材と足部材とを連結する超弾性合金で形成された連結部材とを含むことを特徴とする。 The invention of claim 1 is a heel retaining device for shoes, which comprises: a heel retaining member disposed at the upper part of the heel of the shoe; two foot members disposed at the lower part of the upper of the shoe; It is characterized by including a connecting member made of a superelastic alloy that connects the mold member and the foot member.
請求項２の考案は、足部材が略三角形状であることを特徴とする。 The invention according to claim 2 is characterized in that the foot member has a substantially triangular shape.
請求項３の考案は、踵保型部材と足部材とがＴＰＵ（熱可塑性ポリウレタン）から形成されることを特徴とする。 The invention according to claim 3 is characterized in that the heel support member and the foot member are formed from TPU (thermoplastic polyurethane).
請求項４の考案は、連結部材がニチノール（Ｎｉｔｉｎｏｌ）を素材とする超弾性合金であることを特徴とする。 The invention according to claim 4 is characterized in that the connecting member is a superelastic alloy made of Nitinol.
以上のように、本考案は、靴の踵部の上部に配置する踵保型部材と、靴の甲材の下部に配置する２つの足部材と、踵保型部材と足部材とを連結する超弾性合金で形成された連結部材で構成される。超弾性合金の持つ驚異的な弾性回復性により、使用者が靴を履くとき、使用者の足の踵に踏まれて、靴の踵が潰れると、これに応じて連結部材が大きく屈曲し復元力が増加する。使用者が足の踵を靴の内部に挿入すると、加わっていた圧力が解放され、超弾性合金の持つ驚異的な弾性回復性により瞬時に元の靴の踵の形状に復元することができる。
また、常に靴の踵に上向きの力が作用しているので、使用者は容易に足を靴の内部に挿入することができる。
As described above, the present invention connects the heel protection member disposed above the heel of the shoe, the two foot members disposed below the upper of the shoe, and the heel protection member and the foot member. Consists of a connecting member made of superelastic alloy. Due to the amazing elastic recovery properties of superelastic alloys, when a user puts on shoes, when the heel of the user's foot crushes the heel of the user's foot, the connecting member bends greatly and restores its original shape. Power increases. When the user inserts the heel of the foot into the shoe, the applied pressure is released, and the amazing elastic recovery properties of the superelastic alloy allow the shoe to instantly return to its original shape.
Further, since an upward force is always applied to the heel of the shoe, the user can easily insert the foot into the shoe.
以下、本考案を実施するための形態について図面に基づいて説明する。
図１は、本考案の靴の踵の保型具１の全体構成図である。靴の踵の保型具１は、靴の踵の中央の上部に取付ける踵保型部材１０と靴の踵の甲材の下部に取付ける足部材２０と踵保型部材１０と足部材２０とを連結する連結部材３０で構成される。足部材２０は左足部材２０Ｌと右足部材２０Ｒの２つの足部材２０から構成される。このため連結部材３０も踵保型部材１０と左足部材２０Ｌとを連結する左連結部材３０Ｌと踵保型部材１０と右足部材２０Ｒとを連結する右連結部材３０Ｒの２つの連結部材３０で構成される。
EMBODIMENT OF THE INVENTION Hereinafter, the form for implementing this invention is demonstrated based on drawing.
FIG. 1 is an overall configuration diagram of a shoe heel retainer 1 according to the present invention. The shoe heel retainer 1 includes a heel retainer 10 attached to the upper center of the heel of the shoe, a foot member 20 attached to the lower part of the heel instep of the shoe, the heel retainer 10, and the foot member 20. It is composed of connecting members 30 that connect together. The foot member 20 is composed of two foot members 20, a left foot member 20L and a right foot member 20R. Therefore, the connecting member 30 is also composed of two connecting members 30: a left connecting member 30L that connects the heel guard member 10 and the left foot member 20L, and a right connecting member 30R that connects the heel guard member 10 and the right foot member 20R. Ru.
踵保型部材１０には、左連結部材３０Ｌを差し込むための左連結部材挿入穴１１Ｌと右連結部材３０Ｒを差し込むための右連結部材挿入穴１１Ｒの２つの穴が穿かれている。また、左足部材２０Ｌには左連結部材３０Ｌを差し込むための左連結部材挿入穴２１Ｌが穿かれており、右足部材２０Ｒには右連結部材３０Ｒを差し込むための右連結部材挿入穴２１Ｒが穿かれている。 The heel guard type member 10 has two holes, a left connecting member insertion hole 11L into which the left connecting member 30L is inserted and a right connecting member insertion hole 11R into which the right connecting member 30R is inserted. Further, the left foot member 20L has a left connecting member insertion hole 21L for inserting the left connecting member 30L, and the right foot member 20R has a right connecting member insertion hole 21R for inserting the right connecting member 30R. There is.
踵保型部材１０の材料としては、ＴＰＵ（Ｔｈｅｒｍｏｐｌａｓｔｉｃ Ｐｏｌｙｕｒｅｔｈａｎｅ、熱可塑性ポリウレタン）、ＴＰＥ（Ｔｈｅｒｍｏｐｌａｓｔｉｃ Ｅｌａｓｔｏｍｅｒ、熱可塑性エラストマー）、シリコーン、エラストマー、ネオプレンなどがあるが、耐摩耗性、耐油性、耐薬品性、弾性回復性、および耐屈曲性などの点で、ＴＰＵが好ましい。また、足部材２０の材料としても、同様の観点からＴＰＵが好ましい。 Materials for the heel support member 10 include TPU (thermoplastic polyurethane), TPE (thermoplastic elastomer), silicone, elastomer, and neoprene, but they have good wear resistance, oil resistance, and chemical resistance. TPU is preferable in terms of elastic recovery, bending resistance, and the like. Further, TPU is also preferable as the material for the leg member 20 from the same viewpoint.
連結部材３０は超弾性合金で形成される。超弾性合金とは、大きなひずみで変形しても、変形力を除くと元に戻る合金である。超弾性合金としてはニッケルとチタンの合金であるニチノール（Ｎｉｔｉｎｏｌ）、コバルトクロム合金、銅アルミニウムニッケル合金（Ｃｕ－Ａｌ－Ｎｉ）、銀カドミウム合金などがあるが、ニチノール（Ｎｉｔｉｎｏｌ）が好ましい。ニチノール（Ｎｉｔｉｎｏｌ）はニッケルとチタンの合金で、超弾性と形状記憶特性を持っている。低温では固定された形状を保ち、加熱されると元の形状に戻る。この特性は、メモリ合金として医療機器（ステント、血管フィルターなど）、眼鏡フレーム、歯のワイヤー、ロボット、航空宇宙産業などで使用されている。
本考案は、この超弾性合金の超弾性を利用して、靴の踵の保型を図るものである。
The connecting member 30 is made of a superelastic alloy. A superelastic alloy is an alloy that, even if deformed by a large strain, returns to its original state when the deforming force is removed. Examples of superelastic alloys include Nitinol, which is an alloy of nickel and titanium, cobalt chromium alloy, copper-aluminum-nickel alloy (Cu-Al-Ni), and silver-cadmium alloy, with Nitinol being preferred. Nitinol is an alloy of nickel and titanium that has superelasticity and shape memory properties. It maintains a fixed shape at low temperatures and returns to its original shape when heated. This property has led to its use as a memory alloy in medical devices (stents, blood vessel filters, etc.), eyeglass frames, dental wires, robotics, and the aerospace industry.
The present invention utilizes the superelasticity of this superelastic alloy to maintain the shape of the heel of the shoe.
本考案は各種の形態で実施することができる。以下の記載においては、靴とは片足の靴をいい、甲（アッパー）とは靴の底を除いた上の部分をいい、甲材とは靴の甲の材料をいい、裏材とは靴の内側に用いる材料をいう。甲材は主に、レザー（革）、合成皮革、メッシュ、シンセティックファブリックなどがある。裏材は主に、ラバー（ゴム）、EVA（エチレン酢酸ビニル共重合体）、PU（ポリウレタン）、ゴムアウトソールなどがある。 The invention can be implemented in various forms. In the following description, "shoe" refers to a shoe on one foot, "upper" refers to the upper part of the shoe excluding the sole, "upper material" refers to the material of the upper of the shoe, and "lining material" refers to the shoe. The material used inside the Upper materials mainly include leather, synthetic leather, mesh, and synthetic fabric. The main lining materials include rubber, EVA (ethylene vinyl acetate copolymer), PU (polyurethane), and rubber outsoles.
図２は本考案を靴に実装した場合の一実施形態の斜視図である。踵保型部材１０は靴の踵部４０中央の最高部に取付ける。左足部材２０Ｌは靴の甲材の左側の最下部に取付ける。そして左連結部材３０Ｌを、踵保型部材１０の左連結部材挿入穴１１Ｌと左足部材２０Ｌの左連結部材挿入穴２１Ｌに挿入し、連結する。この時、靴の踵部４０の形状を保持するために、左連結部材３０Ｌが有する超弾性力の上方向への復元力を発揮できるように左連結部材３０Ｌは少し屈曲した長さとすることが好ましい。 FIG. 2 is a perspective view of an embodiment of the present invention implemented in shoes. The heel support type member 10 is attached to the highest part of the center of the heel part 40 of the shoe. The left foot member 20L is attached to the lowermost part of the left side of the upper of the shoe. Then, the left connecting member 30L is inserted into the left connecting member insertion hole 11L of the heel support member 10 and the left connecting member insertion hole 21L of the left foot member 20L, and the left connecting member 30L is connected. At this time, in order to maintain the shape of the heel portion 40 of the shoe, the left connecting member 30L may have a slightly bent length so that the left connecting member 30L can exert the upward restoring force of the superelastic force that the left connecting member 30L has. preferable.
同様に、右足部材２０Ｒは靴の甲材の右側の最下部に取付ける。そして右連結部材３０Ｒを、踵保型部材１０の右連結部材挿入穴１１Ｒと右足部材２０Ｒの右連結部材挿入穴２１Ｒに挿入し、連結する。この時、靴の踵部４０の形状を保持するために、右連結部材３０Ｒが有する超弾性力の上方向への復元力を発揮できるように右連結部材３０Ｒは少し屈曲した長さとすることが好ましい。 Similarly, the right foot member 20R is attached to the lowermost part of the right side of the upper of the shoe. Then, the right connecting member 30R is inserted into the right connecting member insertion hole 11R of the heel support type member 10 and the right connecting member insertion hole 21R of the right foot member 20R to connect them. At this time, in order to maintain the shape of the heel portion 40 of the shoe, the right connecting member 30R may have a slightly bent length so that the right connecting member 30R can exert the upward restoring force of the superelastic force. preferable.
図３（ａ）は、踵保型部材１０の一実施例の正面図で、図３（ｂ）は斜視図である。踵保型部材１０は靴の踵部４０の中央の最高部に取付けられる。その機能は連結部材３０の超弾性合金の復元力により、靴の踵部に常に上方向の力を伝え、靴の踵部４０の形状を保持することにある。踵保型部材１０は、２つの連結部材挿入穴１１である左連結部材挿入穴１１Ｌと右連結部材挿入穴１１Ｒを備え、靴の踵部４０の中央の最高部の形状に沿ったものであり、かつ使用者の足の踵に違和感を与えないように薄く形成し、使用者が靴を履くとき使用者の全体重が使用者の足の踵を通じて、踵保型部材１０に加わっても壊れない構造としている。そこで、この実施例では、踵保型部材１０は図３に示すように材料にＴＰＵを使用し、両端部は連結部材挿入穴１１を穿つため少し厚みをもち、中央部はできるだけ薄く内側に凹な形状としている。ただし、図３の形状に拘るものでなく、踵保型部材１０の機能を果たすことができる形状であれば、この考案の範囲に含まれる。 FIG. 3(a) is a front view of one embodiment of the heel support member 10, and FIG. 3(b) is a perspective view. The heel support member 10 is attached to the highest central part of the heel portion 40 of the shoe. Its function is to constantly transmit an upward force to the heel of the shoe by the restoring force of the superelastic alloy of the connecting member 30, and to maintain the shape of the heel 40 of the shoe. The heel guard type member 10 is provided with two connecting member insertion holes 11, a left connecting member insertion hole 11L and a right connecting member insertion hole 11R, and follows the shape of the highest central part of the heel portion 40 of the shoe. , and is formed to be thin so as not to give a sense of discomfort to the heel of the user's foot, so that it will not break even if the user's entire weight is applied to the heel support member 10 through the heel of the user's foot when the user puts on the shoe. It has no structure. Therefore, in this embodiment, the heel support member 10 is made of TPU as shown in FIG. It has a shape. However, the shape is not limited to that shown in FIG. 3, and any shape that can fulfill the function of the heel support member 10 is within the scope of this invention.
図４（ａ）は、足部材２０の一実施例の正面図で、図４（ｂ）は足部材２０のＡーＡ´断面図である。図４の足部材２０の形状は、図２に示した足部材２０の形状に比べ、正面視略三角形に近く形成されている。これは、図２に示すように正面視略逆Ｔ字型よりも、連結部材３０からの力に耐える強度が得られるからである。また、使用者が足に違和感を与えないように図（ｂ）に示すように薄く形成され、また足部材２０はミシンで甲材に縫い付けるために、足部材縫製部２２は特に薄く形成されている。 4(a) is a front view of one embodiment of the foot member 20, and FIG. 4(b) is a cross-sectional view of the foot member 20 along line AA'. The shape of the foot member 20 in FIG. 4 is formed closer to a substantially triangular shape when viewed from the front than the shape of the foot member 20 shown in FIG. This is because, as shown in FIG. 2, the strength to withstand the force from the connecting member 30 can be obtained more than the substantially inverted T-shape when viewed from the front. In addition, the foot member sewing portion 22 is formed to be thin, as shown in Figure (b), so as not to give the user a sense of discomfort in the foot, and because the foot member 20 is sewn to the upper material using a sewing machine. ing.
図５は、靴の踵の保型具１を靴の踵部４０へ装着した様子を説明するための模式図である。図５は靴の裏材をすべて取り除いた状態を示している。
踵保型部材１０は、使用者の足の踵に違和感を与えないように、２mm厚みのクッション材を裏当てした生地で踵保型部材１０全体を包み込み、これを本縫いし、靴の踵部中央の最高部４１の靴の踵部甲材裏部４２と裏材（図示せず。）との間にノリで固定して取付ける。
FIG. 5 is a schematic diagram for explaining how the shoe heel retainer 1 is attached to the heel portion 40 of the shoe. Figure 5 shows the shoe with all the soles removed.
The heel protection type member 10 is made by wrapping the entire heel protection type member 10 with fabric lined with a 2 mm thick cushioning material and lock-stitching it so as not to cause discomfort to the heel of the user's foot. It is attached by fixing with glue between the back of the heel upper material 42 of the shoe at the highest part 41 in the center and the backing material (not shown).
足部材２０は、甲材の踵部最下部４３で足部材縫製部２２と甲材とをミシン糸で縫い付け固定する。なお、連結部材３０が使用者の足に直接当たらないように、連結部材３０は不織布で覆う（図示せず。）。左連結部材３０Ｌの一方を踵保型部材１０の左連結部材挿入穴１１Ｌに差し込み、他方を左足部材２０Ｌの左連結部材挿入穴２１Ｌに差し込む。また、右連結部材３０Ｒの一方を踵保型部材１０の右連結部材挿入穴１１Ｒに差し込み、他方を右足部材２０Ｒの右連結部材挿入穴２１Ｒに差し込む。このとき、連結部材３０は靴の踵部４０に上方向への力を発生させるために、図に示すように少し屈曲する長さとすることが好ましい。
なお、本実施例で示した本考案の靴の踵の保型具１の装着方法に拘ることなく、本考案の要旨に沿った別の装着方法を採用してもよい。
The foot member 20 is fixed by sewing the foot member sewing part 22 and the upper material with sewing thread at the lowest heel portion 43 of the upper material. Note that the connecting member 30 is covered with a nonwoven fabric (not shown) so that the connecting member 30 does not directly contact the user's feet. One of the left connecting members 30L is inserted into the left connecting member insertion hole 11L of the heel support type member 10, and the other is inserted into the left connecting member insertion hole 21L of the left foot member 20L. Further, one of the right connecting members 30R is inserted into the right connecting member insertion hole 11R of the heel support type member 10, and the other is inserted into the right connecting member insertion hole 21R of the right leg member 20R. At this time, the connecting member 30 preferably has a length that is slightly bent as shown in the figure in order to generate upward force on the heel 40 of the shoe.
Note that, without being limited to the method of attaching the shoe heel retaining device 1 of the present invention shown in this embodiment, another method of attaching the shoe heel retainer 1 according to the present invention may be adopted.
図６は靴の踵の保型具１の作用の説明図である。図６（ａ）は、靴の踵部４０の上部に圧力が加わっていない状態を示している。前記したように、超弾性合金からなる連結部材３０は少し屈曲して取り付けられているため、その復元力により、靴の踵部４０の中央最上部４１に取り付けられた踵保型部材１０には、常に上方向の力が働き、靴の踵部４０が常に立ち上がった形状を保持している。図６（ｂ）は、使用者が靴を履くとき、使用者の足の踵が靴の踵部４０に当接し少し踏み込んだ状態を表わしている。この時、連結部材３０は、使用者の足の踵の圧力に応じて、図５（ａ）よりも屈曲する。図６（ｃ）は、使用者が足の踵を靴の内部に挿入するために、更に使用者の足の踵で靴の踵部４０を踏み込むので、靴の踵部４０が潰れ、連結部材３０が大きく屈曲する状態を示している。この時、連結部材３０はその屈曲に応じて、復元力がさらに増加し、靴の踵部４０の上部を上方向に押し上げる力が益々増加するので、使用者は容易に足の踵を靴内部に滑り込ませることができる。図６（ｄ）は使用者の足の踵部が靴の中に入ると、靴の踵部４０に対する圧力が解放され、その開放と同時に連結部材３０の驚異的な弾性回復性効果により、元の靴の踵部４０の形状に復元された状態を示す。 FIG. 6 is an explanatory diagram of the action of the shoe heel retainer 1. FIG. 6(a) shows a state in which no pressure is applied to the upper part of the heel portion 40 of the shoe. As mentioned above, since the connecting member 30 made of a superelastic alloy is attached with a slight bend, its restoring force causes the heel retaining member 10 attached to the center top 41 of the heel portion 40 of the shoe to , an upward force always acts, and the heel portion 40 of the shoe always maintains its upright shape. FIG. 6(b) shows a state in which, when the user puts on the shoes, the heel of the user's foot contacts the heel portion 40 of the shoe and steps into it slightly. At this time, the connecting member 30 is bent more than in FIG. 5(a) in response to the pressure of the heel of the user's foot. In FIG. 6(c), in order to insert the heel of the foot into the inside of the shoe, the user further steps on the heel portion 40 of the shoe with the heel of the user's foot, so the heel portion 40 of the shoe is crushed and the connecting member 30 shows a state in which it is greatly bent. At this time, the restoring force of the connecting member 30 further increases as the connecting member 30 bends, and the force pushing up the upper part of the heel portion 40 of the shoe further increases, so that the user can easily move the heel of the foot inside the shoe. can be slipped into. FIG. 6(d) shows that when the heel of the user's foot enters the shoe, the pressure on the heel 40 of the shoe is released, and at the same time, due to the amazing elastic recovery effect of the connecting member 30, the pressure on the heel 40 of the shoe is released. This figure shows the state in which the heel part 40 of the shoe has been restored to its original shape.
本考案の実施形態は、本実施例に示した形状に拘るものでなく、本考案の要旨である超弾性合金の驚異的な弾性回復性を利用して、靴の踵の保型を図るという趣旨に反しない限り、別の形態を採用してもよい。 The embodiment of the present invention is not limited to the shape shown in this example, but the gist of the present invention is to utilize the amazing elastic recovery properties of superelastic alloys to maintain the shape of the heel of the shoe. Other forms may be adopted as long as they do not contradict the purpose.
