Description

本発明は、靴に関するものである。 The present invention relates to shoes.

従来からある靴の大半は、足甲頂点に靴紐による締付調整部が配置されている。 Most conventional shoes have a tightening adjuster with a shoelace at the apex of the instep.

ところで、足には、足甲頂点を中心に太く重要な血管が存在している。そのため、大半の靴では、靴紐を締め上げると、当該血管を圧迫し易い構造となっている。 By the way, the foot has thick and important blood vessels around the apex of the instep. Therefore, most shoes have a structure in which the blood vessel is easily compressed when the shoelaces are tightened.

また、締付調整部は、シュータンや靴紐が挿通するハトメ（紐通し孔）が設けられる羽根などにより厚く形成されるため、締付調整部が足甲頂点に位置すると、この点でも足甲頂点付近の血管を圧迫し易い構造となる。 In addition, since the tightening adjusting portion is formed thickly by means of blades or the like provided with eyelets (lacing holes) through which the shoe tongue or shoelace is inserted, when the tightening adjusting portion is positioned at the apex of the instep, the instep can be It becomes a structure that easily compresses blood vessels near the apex.

足甲頂点付近の血管が圧迫されると、足のむくみや疲労の原因になるのみならず、全身の血行・血流が阻害され、歩行運動による筋肉収縮に伴う血流改善効果も阻害される。 When the blood vessels near the top of the instep are compressed, it not only causes swelling and fatigue in the legs, but also impedes blood circulation and blood flow throughout the body, impairing the blood flow improvement effect associated with muscle contraction due to walking exercise. .

なお、特許文献１には、足甲頂点をよけた外側寄り位置に締付調整部が設けられた靴が開示されているが、上述の血管の圧迫に関する知見は何ら記載されていない。 Although Patent Document 1 discloses a shoe having a tightening adjustment portion at a lateral position avoiding the apex of the instep, it does not disclose any information regarding the compression of blood vessels.

本発明は上述のように構成したから、足甲頂点付近の血管を圧迫し難く、可及的に全身の血行・血流を阻害し難い靴となる。 Since the present invention is configured as described above, it is possible to provide a shoe that hardly presses the blood vessels near the top of the instep and that hinders the circulation and blood flow of the whole body as much as possible.

本実施例に係る左足用の靴の側面図である。FIG. 2 is a side view of the left foot shoe according to the present embodiment; 本実施例に係る左足用の靴の平面図である。1 is a plan view of a left foot shoe according to an embodiment; FIG. 足甲頂点付近の血管と締付調整部との関係を示す概略図である。FIG. 4 is a schematic diagram showing the relationship between the blood vessels near the top of the instep and the tightening adjuster.

好適と考える本発明の実施形態を、図面に基づいて本発明の作用を示して簡単に説明する。 A preferred embodiment of the present invention will be briefly described with reference to the drawings showing the operation of the present invention.

締付調整部10が、図３に図示したように、足30の足甲頂点付近の血管31からずれた足甲部２ａの外側寄りに設けられることで、締め上げ時の足甲頂点付近の血管31の圧迫、締付調整部10の羽根部等の厚みによる当該血管31の圧迫が生じ難くなる。 As shown in FIG. 3, the tightening adjuster 10 is provided on the outer side of the instep 2a away from the blood vessel 31 near the instep apex of the foot 30, so that the area near the instep apex when tightening is adjusted. Compression of the blood vessel 31 and compression of the blood vessel 31 due to the thickness of the wings of the tightening adjustment section 10 are less likely to occur.

また、靴紐13として引っ張り操作によりこぶ状部13ａを伸長弾性変形可能なものを採用することで、靴紐13による血管の圧迫も可及的に抑制される。 In addition, by adopting a shoelace 13 that can be stretched and elastically deformed by a pulling operation, the pressure on blood vessels due to the shoelace 13 is suppressed as much as possible.

更に、靴紐13の両端部をいずれも足甲部２ａの外側寄りに設けた止着部14に止着することによっても、足甲頂点付近の重要な血管31の圧迫が可及的に阻止される。即ち、例えば、靴紐の内側の羽根部の最後の紐通し孔を通過して引き出された一端部を足甲部（内側の羽根部）の内側寄りに止着し、外側の羽根部の最後の紐通し孔を通過して引き出された他端部を足甲部（外側の羽根部）の外側寄りに止着した場合には、前記靴紐の一端部側が足甲頂点を跨ぐことで足甲頂点付近の血管を圧迫する可能性があるが、本発明によればこのような問題はない。 Furthermore, by fastening both ends of the shoelace 13 to fastening portions 14 provided on the outer side of the instep 2a, pressure on important blood vessels 31 near the apex of the instep can be prevented as much as possible. be done. That is, for example, one end portion of the shoelace passed through the last lacing hole of the inner wing portion and pulled out is attached to the inner side of the instep portion (inner wing portion), and the last of the outer wing portion is attached. When the other end pulled out through the lacing hole is fastened to the outer side of the instep (outer wing), the one end of the shoelace straddles the apex of the instep and the foot Although there is a possibility of compressing blood vessels near the apex of the instep, this problem does not occur according to the present invention.

更に、靴紐13の両端部が共に足甲部２ａの外側寄りに揃って設けられることでデザイン上も極めて美しいものとなる。 In addition, both ends of the shoelace 13 are aligned on the outer side of the instep 2a, which makes the design very beautiful.

また、例えば、爪先保持部20に先芯部材を設けず、且つ、踵保持部19に月型芯部材を設けずに、踵保持部19に踵の抜けを防止する足幅方向に延びる帯状の抜け防止体15を設けた場合には、踵の抜けを防止しつつ、靴の前後方向（爪先・踵方向）からの圧迫を低減でき、足の血管の圧迫を良好に抑制できるものとなる。 Further, for example, the toe holding part 20 is not provided with a toe core member and the heel holding part 19 is not provided with a moon-shaped core member. When the slip-off prevention member 15 is provided, it is possible to reduce the pressure from the front and back direction (toe/heel direction) of the shoe while preventing the heel from slipping off, and to suppress the pressure on the blood vessels of the foot.

従って、本発明は、足甲頂点付近の血管を圧迫し難く、可及的に全身の血行・血流を阻害し難いものとなる。 Therefore, according to the present invention, it is difficult to press the blood vessels near the apex of the instep, and it is possible to inhibit blood circulation and blood flow throughout the body as little as possible.

本発明の具体的な実施例について図面に基づいて説明する。 A specific embodiment of the present invention will be described with reference to the drawings.

本実施例は、甲被部２（アッパー部）の足甲部２ａの外側寄りに、対向状態で複数の紐通し孔11が並設された一対の羽根部12と、この紐通し孔11に挿通される靴紐13とで構成された締付調整部10を有する靴に本発明を適用した例である。図中、符号１は底部（ソール部）である。 In this embodiment, a pair of blades 12 in which a plurality of lacing holes 11 are arranged side by side in an opposing state on the outer side of the instep 2a of the instep 2 (upper portion), and the lacing holes 11 This is an example in which the present invention is applied to a shoe having a tightening adjusting portion 10 configured with a shoelace 13 to be inserted. In the figure, reference numeral 1 denotes a bottom portion (sole portion).

本実施例は、靴紐13として、紐長手方向に前記紐通し孔11の孔径よりも大径に形成されると共に、伸縮自在に弾性変形して引っ張り操作により該引っ張り操作方向に伸長弾性変形して前記紐通し孔11の孔径よりも小径に変形するこぶ状部13ａが複数並設されたこぶ領域部を有する靴紐13を採用している。 In this embodiment, the shoelace 13 is formed to have a diameter larger than the diameter of the lace through hole 11 in the longitudinal direction of the lace, and is elastically deformed to extend and elastically deform in the pulling operation direction by a pulling operation. The shoelace 13 has a hump region portion in which a plurality of hump-shaped portions 13a deformed to have a smaller diameter than the diameter of the lace through-hole 11 are arranged side by side.

この靴紐13は、前記紐通し孔11に挿通され前記足甲部２ａに装着された状態にて最後に通過させる紐通し孔11を通過して引き出された前記こぶ領域部を引っ張り操作することで、前記紐通し孔11の内側に係止するこぶ状部13ａが前記引っ張り操作により伸長弾性変形して前記紐通し孔11よりも小径となり、前記紐通し孔11を通過移動して締め上げることができ、この締め上げ状態にて前記引っ張り操作を解除することで、前記紐通し孔11を通過した前記こぶ状部13ａが、小径状態から紐通し孔11の孔径よりも大径なもとの状態（非変形状態）に戻り変形し、前記最後に通過した紐通し孔11に対して戻り通過移動不能な状態となる。 The shoelace 13 is passed through the lacing hole 11 and is passed through the last through the lacing hole 11 while attached to the instep 2a. The knob-shaped portion 13a engaged inside the lacing hole 11 is stretched and elastically deformed by the pulling operation, becomes smaller in diameter than the lacing hole 11, moves through the lacing hole 11, and is tightened. By releasing the pulling operation in this tightened state, the hump-shaped portion 13a that has passed through the lacing hole 11 changes from the small diameter state to the original diameter larger than that of the lacing hole 11. It is deformed back to the state (undeformed state), and becomes incapable of returning and passing through the stringing hole 11 through which it passed last.

また、本実施例の靴紐13としては、両端部に設けられる前記こぶ領域部の間の略全域（長手方向中央部）にわたって紐通し孔11の孔径よりも小径で且つ略一定の太さに形成される太さ一定領域部が設けられたものを採用している。なお、前記こぶ領域部間に、上述の太さ一定領域部ではなく、紐通し孔11の孔径よりも小径な小径こぶ部が間隔をおいて複数並設された小径こぶ領域部が設けられたものを採用しても良い。 In addition, the shoelace 13 of this embodiment has a diameter smaller than the diameter of the lacing hole 11 and a substantially constant thickness over substantially the entire area (central portion in the longitudinal direction) between the hump regions provided at both ends. The one provided with the constant-thickness area|region part formed is employ|adopted. In addition, instead of the constant thickness area described above, a small-diameter bump area having a plurality of small-diameter bumps smaller than the hole diameter of the lacing hole 11 arranged side by side at intervals is provided between the bump areas. You can adopt something.

また、本実施例の羽根部12同士の間隔は、隙間なくぴったりと閉じることが可能となる間隔に設定されている。即ち、靴紐13の締付調整によって、羽根部12同士の間に隙間がない一直線の境界を呈する外観とすることもできる。 In addition, the interval between the blade portions 12 of this embodiment is set to be such an interval that the blades 12 can be tightly closed without any gap. In other words, by adjusting the tightening of the shoelace 13, it is possible to make the outer appearance exhibiting a straight boundary without gaps between the blades 12. FIG.

また、甲被部２には、前記靴紐11の両端部を夫々止着可能な止着部14が、前記足甲部２ａの外側寄りに設けられている。本実施例においては、止着部14は、締付調整部10より外側であって、外側の前記羽根部12の最上位の紐通し孔11および内側の前記羽根部12の前記最上位の紐通し孔11の鉛直下方位置に設けられている。 In addition, the instep portion 2 is provided with fastening portions 14 to which both ends of the shoelace 11 can be fastened, respectively, on the outer sides of the instep portion 2a. In this embodiment, the fastening portion 14 is located outside the tightening adjustment portion 10, and includes the uppermost cord through hole 11 of the outer blade portion 12 and the uppermost cord hole of the inner blade portion 12. It is provided vertically below the through hole 11 .

また、外側の前記羽根部12の最上位の紐通し孔11と内側の前記羽根部12の最上位の紐通し孔11とは、夫々の鉛直下方への直線が平行となるような位置（靴の前後方向においてずれた位置）に設けられている。 In addition, the uppermost lacing hole 11 of the outer wing portion 12 and the uppermost lacing hole 11 of the inner wing portion 12 are positioned so that the straight lines extending vertically downward are parallel to each other (shoes). position shifted in the front-rear direction).

止着部14は、紐通し孔11と同様に、こぶ状部13ａが小径状態では通過移動可能で、もとの大径状態では通過移動不能な靴紐挿通孔（図示省略）を有している。具体的には、丸みを帯びたほぼ菱形状の表面部の裏側に靴紐挿通孔が穿設された表面部に隠れる大きさの基部（図示省略）が設けられている。靴紐挿通孔は、鉛直方向（上下方向）を向く孔であり、靴長手方向に２つ平行に並設されている。この靴紐挿通孔に最上位の紐通し孔11を通過した靴紐13の端部を、夫々上記同様に通過させ戻り通過不能とすることで、体裁よく止着することができる。 The fixing portion 14 has a shoelace insertion hole (not shown) that can pass through when the hump portion 13a is small in diameter, but cannot pass through when it is in its original large diameter state, similar to the lace insertion hole 11. there is Specifically, a base portion (not shown) of a size that is hidden behind a surface portion having a shoelace insertion hole is provided on the back side of a rounded diamond-shaped surface portion. The shoelace insertion holes are holes facing in the vertical direction (vertical direction), and are arranged side by side in two in the longitudinal direction of the shoe. The ends of the shoelace 13 that have passed through the uppermost lacing hole 11 are passed through the shoelace insertion holes in the same manner as described above, so that they cannot be returned and fastened in a good appearance.

また、靴紐13の長さは、両端が止着部14に止着した状態で地面（床）に接触しない長さとする。具体的には、両端が止着部14に止着した状態でソール部１より上の位置となる長さとする。 Also, the length of the shoelace 13 is such that it does not come into contact with the ground (floor) when both ends are fastened to the fastening portions 14 . Specifically, the length is such that it is positioned above the sole portion 1 when both ends are fastened to the fastening portions 14 .

なお、止着部14を外側寄りと内側寄りに夫々設ける構成としても良い。この場合、外側の羽根部12の最後に通過する紐通し孔11および内側の羽根部12の最後に通過する紐通し孔11を通過した端部を夫々、外側の羽根部12より外側寄りの止着部14および内側の羽根部12より内側寄りの止着部14に夫々止着することになる。また、この場合、靴紐挿通孔は各止着部14に夫々１つずつ設ける。 It should be noted that the fixing portions 14 may be provided on the outer side and the inner side, respectively. In this case, the ends passing through the last passing lacing hole 11 of the outer wing portion 12 and the last passing lacing hole 11 of the inner wing portion 12 are respectively attached to the outer side of the outer wing portion 12. The attachment portion 14 and the fastening portion 14 closer to the inner side than the inner blade portion 12 are attached to each other. In this case, one shoelace insertion hole is provided in each fixing portion 14 .

また、本実施例は、爪先保持部20を構成する表部材17と裏部材（図示省略）との間に該爪先保持部20を補強する先芯部材が設けられておらず、且つ、踵保持部19を構成する表部材18と裏部材（図示省略）との間に該踵保持部19を補強する月型芯部材が設けられていない。従って、使用者の爪先および踵が先芯部材および月型芯部材により圧迫されない（動きが阻害され難い。）。 Further, in this embodiment, no toecap member for reinforcing the toe holding portion 20 is provided between the front member 17 and the back member (not shown) constituting the toe holding portion 20, and the heel holding portion 20 is A moon-shaped core member that reinforces the heel holding portion 19 is not provided between the front member 18 and the back member (not shown) that constitute the portion 19 . Therefore, the toe and heel of the user are not pressed by the toecap member and the moon-shaped core member (movement is less likely to be hindered).

本実施例では、踵が抜けないように、踵保持部19（の外側）に踵の抜けを防止する足幅方向に延びる帯状の抜け防止体15が設けられている。抜け防止体15は踵の後側外形状に沿って半円弧状に設けられている。抜け防止体15は、適度な伸縮性を有する素材、例えばシリコン等で作製することができる。図中符号16はプルストラップである。 In this embodiment, a band-shaped slip-off prevention member 15 extending in the width direction of the foot is provided on (outside of) the heel holding portion 19 to prevent the heel from slipping off. The coming-off prevention member 15 is provided in a semi-circular shape along the outer shape of the rear side of the heel. The removal prevention member 15 can be made of a material having appropriate elasticity, such as silicon. Reference numeral 16 in the figure is a pull strap.

本実施例は上述のように構成したから、締付調整部10が、図３に図示したように、足30の足甲頂点付近の血管31からずれた足甲部２ａの外側寄りに設けられることで、締め上げ時の足甲頂点付近の血管31の圧迫、締付調整部10の羽根部等の厚みによる当該血管31の圧迫が生じ難くなる。 Since this embodiment is constructed as described above, the tightening adjustment portion 10 is provided on the lateral side of the instep 2a, which is displaced from the blood vessel 31 near the top of the instep of the foot 30, as shown in FIG. As a result, the pressure on the blood vessel 31 near the top of the instep during tightening and the pressure on the blood vessel 31 due to the thickness of the wings of the tightening adjustment portion 10 are less likely to occur.

更に、靴紐13の（例えば最後にして最上位の紐通し孔11を通過した）両端部をいずれも足甲部２ａの外側寄りに設けた止着部14に止着することによっても、足甲頂点付近の重要な血管31の圧迫が可及的に阻止される。 Further, by fastening both ends of the shoelace 13 (for example, passing through the uppermost lace hole 11 at the end) to fastening portions 14 provided on the outer side of the instep 2a, the foot can be Compression of important blood vessels 31 near the top of the instep is prevented as much as possible.

また、爪先保持部20に先芯部材を設けず、且つ、踵保持部19に月型芯部材を設けずに、踵保持部19に踵の抜けを防止する足幅方向に延びる帯状の抜け防止体15を設けることで、踵の抜けを防止しつつ、靴の前後方向（爪先・踵方向）からの圧迫を低減でき、足の血管の圧迫を良好に抑制できるものとなる。 In addition, without providing a toe core member in the toe holding part 20 and without providing a moon-shaped core member in the heel holding part 19, the heel holding part 19 has a band-shaped slip-off prevention band extending in the foot width direction that prevents the heel from slipping out. By providing the body 15, it is possible to reduce the pressure from the front and back direction (toe/heel direction) of the shoe while preventing the heel from coming off, and to suppress the pressure on the blood vessels of the foot.

従って、本実施例は、足甲頂点付近の血管を圧迫し難く、可及的に全身の血行・血流を阻害し難いものとなる。 Therefore, in this embodiment, it is difficult to press the blood vessels in the vicinity of the top of the foot, and it is possible to prevent the circulation and blood flow of the whole body as little as possible.

なお、図面では左足用の靴について説明しているが、右足用の靴についても（対称となるだけで）同様である。 Although the drawings describe the left-foot shoe, the same applies to the right-foot shoe (only symmetrical).
