従来より、鼻緒の端部を草履等の台に係止固定するための鼻緒係止具が知られている。例えば、特許文献１には、草履台の底に形成された収納凹部に収納される鼻緒係止具について、鼻緒の端部を保持するための保持溝が形成されたベース部と、ベース部にヒンジで連結された楔部とを備えたものが開示されている。この鼻緒係止具は、鼻緒の端部としての芯材を楔部に巻き付けた状態で、この楔部を保持溝に嵌め込むことにより、鼻緒の端部を台に係止固定するようになっている。 2. Description of the Related Art Conventionally, a umbilicus locking tool for locking and fixing an end of a umbilicus to a platform such as sandals is known. For example, Patent Document 1 discloses a base part in which a holding groove for holding an end part of a nose is formed on a nose strap engaging tool stored in a storage concave part formed on the bottom of a sandals, and a base part. The thing provided with the wedge part connected with the hinge is disclosed. In this state, the end of the umbilical cord is locked and fixed to the base by fitting the wedge into the holding groove in a state where the core material as the end of the umbilical cord is wound around the wedge. ing.
特許文献２には、草履台の収納凹部に収納される固定金具が鼻緒係止具として記載されている。特許文献２では、鼻緒の端部にループ状の係止紐が設けられており、この紐部材を固定金具に係止させることで鼻緒の端部を台に係止固定するようになっている。 Patent Document 2 describes a fixing bracket stored in a storage recess of a sandals as a cord lock. In Patent Document 2, a loop-like locking string is provided at the end of the nose, and the end of the nose is locked and fixed to the base by locking the string member to the fixing bracket. .
上記特許文献１の鼻緒係止具では、鼻緒の端部を任意の位置において保持溝に固定できるので、台の上での鼻緒の長さを調整することができる。一方、上記特許文献２のものでは、ループ状の係止紐が固定金具から外れ易い構成となっているので、鼻緒を容易に交換することが可能である。 In the umbilical cord locking tool of Patent Document 1, since the end portion of the umbilical cord can be fixed to the holding groove at an arbitrary position, the length of the umbilical cord on the table can be adjusted. On the other hand, in the thing of the said patent document 2, since the loop-shaped latching string becomes a structure which is easy to remove | deviate from a fixing metal fitting, it is possible to replace | exchange a nose easily.
しかし、上記特許文献１，２の鼻緒係止具では、鼻緒の端部を台に係止固定した後は台の上での鼻緒の長さが所定長さに規定されるので、歩き続けると鼻緒が足に強く擦れることで足が痛くなり易いという問題がある。 However, in the umbilical cord locking device of Patent Documents 1 and 2, after the end portion of the umbilical cord is locked and fixed to the table, the length of the umbilical cord on the table is defined as a predetermined length. There is a problem that the legs tend to hurt when the thongs rub against the legs.
本発明は、かかる点に鑑みてなされたものであり、その目的とするところは、鼻緒係止具の構成に工夫を凝らすことにより、鼻緒に当たる足の痛みを大幅に抑制することにある。 This invention is made | formed in view of this point, The place made into the objective is to suppress the pain of the leg which hits a nose greatly by devising the structure of a nose cord locking tool.
第１の発明に係る鼻緒係止具は、履物における台の底に形成されると共に該台の上側に連通した収納凹部に収納され、上記台の上から挿入された鼻緒の端部を上記収納凹部内で係止する。鼻緒係止具は、上記収納凹部の底に設置され、上記鼻緒の端部が挿通される鼻緒挿通部を有するベース部と、上記ベース部から上記鼻緒挿通部に臨むように延びると共に該ベース部よりも上記収納凹部の開口端側に配置され、上記鼻緒挿通部に挿通された上記鼻緒の端部が中央に取付けられる取付部とを備えている。上記鼻緒係止具は、上記ベース部と上記取付部とが一体形成により構成された単一の部材からなる。そして、上記取付部は、基端側が上記ベース部と一体に形成される一方、先端側が上記ベース部から離隔したアーム状に形成されることによって、上記取付部が弾性を有することにより、該取付部に取付られた上記鼻緒の端部が上記台に対して上下に移動可能になっている。上記ベース部には、上記取付部の先端に対向する領域に溝が形成されており、上記取付部に取付けられた上記鼻緒の端部が引き上げられて上記取付部の先端が上記ベース部側である上側へ移動したときに、当該取付部の先端は、上記溝内に嵌まり込むと共に、当該溝内に嵌まり込んだ状態で該溝に沿って側方へ移動可能になっている。 The umbilical cord locking device according to the first aspect of the present invention is formed at the bottom of the base of the footwear and stored in a storage recess communicated with the upper side of the base. Lock in the recess. And a base part having a nose insertion part that is installed at the bottom of the storage recess and through which the end part of the nose is inserted, and extends from the base part so as to face the nose insertion part, and the base part And an attachment portion that is disposed closer to the opening end side of the storage recess and to which the end portion of the umbilical cord inserted through the nasal passage insertion portion is attached at the center . The umbilical cord anchoring device is composed of a single member in which the base portion and the attachment portion are integrally formed. Then, the mounting portion, while the proximal end side is integrally formed with said base portion, by Rukoto tip side is formed in the arm-shaped spaced from the base portion, the mounting portion by an elastic, with said mounting An end portion of the cord attached to the portion is movable up and down with respect to the table. The base portion has a groove formed in a region facing the tip of the attachment portion, and the end of the nose attached to the attachment portion is pulled up so that the tip of the attachment portion is on the base portion side. When moved to a certain upper side, the tip of the mounting portion fits in the groove and can move sideways along the groove while being fitted in the groove.
第２の発明に係る鼻緒係止具は、上記取付部が、上記ベース部と反対側へ突出した湾曲形状を有している。 In the cord anchor according to the second aspect of the present invention, the attachment portion has a curved shape protruding to the side opposite to the base portion.
第１の発明によれば、鼻緒の端部は、台の上から収納凹部に挿入され、鼻緒係止具のベース部における鼻緒挿通部を挿通した状態で、鼻緒係止具の取付部に取付られる。この取付部が弾性を有しているので、取付部に取付られた鼻緒の端部は台に対して上下に移動することができる。言い換えれば、台の上における鼻緒の長さを、足の動きに応じて変化させることができるのである。よって、本発明によると、台上の足の動きに追従して鼻緒が上下に移動できるので、鼻緒に当たる足の痛みを大幅に抑制できる。さらに、鼻緒を足に適度にフィットさせた状態で足の動きに追従させることができるので、履物の装着感を高めることができる。 According to the first aspect of the present invention, the end of the umbilical cord is inserted into the storage recess from the top of the base, and is attached to the attachment portion of the umbilical cord locking device in a state where the ligament insertion portion of the base portion of the lanyard locking device is inserted. It is done. Since this attachment part has elasticity, the end part of the nose attached to the attachment part can move up and down with respect to the base.

Therefore, according to the present invention, since the umbilical cord can move up and down following the movement of the foot on the table, the pain of the foot hitting the vellus can be greatly suppressed. Furthermore, since the movement of the foot can be followed in a state in which the nose is properly fitted to the foot, the feeling of wearing the footwear can be enhanced.
第２の発明によれば、取付部を湾曲形状としたので、その全体の弾性を効率よく利用して鼻緒の端部を好適に上下移動させることができる。 According to the second aspect of the present invention, since the attachment portion has a curved shape, the end portion of the nose can be suitably moved up and down by efficiently utilizing the elasticity of the entire attachment portion.
以下、本発明の実施形態を図面に基づいて詳細に説明する。尚、本発明は、以下の実施形態に限定されるものではない。 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The present invention is not limited to the following embodiment.
図１は、草履１の外観を示す斜視図である。図２は、本実施形態における鼻緒係止具１０が装着された台２の断面を一部拡大して示している。図３〜図５は、鼻緒係止具１０を示している。本実施形態では、鼻緒係止具１０が取付られる履物として草履１を例に挙げて説明する。また、本実施形態では草履１のつま先側を前側とし、踵側を後側として説明する。 FIG. 1 is a perspective view showing the appearance of sandals 1. FIG. 2 is a partially enlarged cross-sectional view of the table 2 on which the umbilical cord anchor 10 according to this embodiment is mounted. 3 to 5 show the umbilical cord anchor 10. In the present embodiment, sandals 1 will be described as an example of footwear to which the umbilical cord anchor 10 is attached. Further, in the present embodiment, the toe side of the sandals 1 will be described as the front side, and the heel side will be described as the rear side.
図１に示すように、草履１は、足を乗せる本体部分である台２と、台２に取付られた鼻緒３とを備えている。鼻緒３は前側に設けられた先緒４を有している。鼻緒３の内部には紐からなる芯材５が挿通されている。図２にも示すように、芯材５は、先緒４の先端よりも長く延びている。また、図示を省略するが、芯材５は、鼻緒３の後側部分である後緒６の後端よりも長く延びている。ここで、本実施形態において、鼻緒３の端部とは、先緒４の先端側に延びている芯材５の部分に相当する。また、後述するように、後緒６の後端側に延びている芯材５の部分も鼻緒３の端部に相当する。 As shown in FIG. 1, the sandals 1 are provided with a base 2 that is a main body part on which a foot is placed, and a nose 3 attached to the base 2. The thong 3 has a forehead 4 provided on the front side. A core material 5 made of a string is inserted into the umbilical cord 3. As shown in FIG. 2, the core material 5 extends longer than the tip of the forehead 4. Although not shown, the core material 5 extends longer than the rear end of the back 6 which is the rear portion of the nose 3. Here, in the present embodiment, the end portion of the umbilical cord 3 corresponds to the portion of the core material 5 extending to the distal end side of the leading portion 4. Further, as will be described later, the portion of the core material 5 extending to the rear end side of the back 6 also corresponds to the end of the nose 3.
台２には、鼻緒３の端部が差し込まれる孔７，８が形成されている。前側の孔７（つまり前壺７）には、先緒４及び芯材５が差し込まれる一方、後側の孔８には、図示を省略するが、後緒６及び芯材５が差し込まれる。以下、本実施形態では特に、前壺７の近傍における鼻緒３の取付構造について説明する。 The base 2 is formed with holes 7 and 8 into which the ends of the umbilical cord 3 are inserted. The front 4 and the core 5 are inserted into the front hole 7 (that is, the front collar 7), while the rear 6 and the core 5 are inserted into the rear hole 8 although illustration is omitted. Hereinafter, in the present embodiment, the attachment structure of the umbilical cord 3 in the vicinity of the forehead 7 will be described in particular.
図２に示すように、台２の前側部分の底には、収納凹部２０が形成されている。収納凹部２０は、前壺７によって台２の上側に連通している。言い換えれば、前壺７の下端は、収納凹部２０における上側の内面である収納凹部２０の底２０ａで開放されている。
なお、台２の裏面には、柔軟性に富む合成樹脂等の底材２１が貼り付けられており、その一部が収納凹部２０を閉塞する舌片２２となっている。
As shown in FIG. 2, an accommodation recess 20 is formed at the bottom of the front portion of the table 2. The storage recess 20 communicates with the upper side of the table 2 by the front rod 7. In other words, the lower end of the front saddle 7 is opened at the bottom 20 a of the storage recess 20 which is the upper inner surface of the storage recess 20.
Note that a flexible base material 21 such as a synthetic resin is affixed to the back surface of the base 2, and a part of the base material 21 is a tongue piece 22 that closes the housing recess 20.
鼻緒係止具１０は、収納凹部２０に収納され、台２の上から挿入された先緒４の芯材５を、この収納凹部２０内で係止するように構成されている。鼻緒係止具１０は、図２〜図４に示すように、ベース部１１と取付部１２とを備えている。 The umbilical cord locking device 10 is housed in the housing recess 20 and is configured to lock the leading core material 5 inserted from above the table 2 within the housing recess 20. As shown in FIGS. 2 to 4, the umbilical cord anchor 10 includes a base portion 11 and an attachment portion 12.
鼻緒係止具１０は、その全体が例えばＡＢＳ、ポリカーボネート又はポリアセタール等の合成樹脂によって形成されている。ベース部１１及び取付部１２は互いに一体に形成されている。なお、鼻緒係止具１０は、合成樹脂以外にも例えば金属材料等によって形成することも可能である。 The umbilical cord anchor 10 is entirely formed of a synthetic resin such as ABS, polycarbonate, or polyacetal. The base portion 11 and the attachment portion 12 are formed integrally with each other. Note that the umbilical cord anchor 10 may be formed of, for example, a metal material other than the synthetic resin.
ベース部１１は、収納凹部２０の底２０ａに設置され、先緒４の芯材５が挿通される鼻緒挿通部１３を有している。ベース部１１は、例えばリング板状に形成されており、その内側の開口部分が鼻緒挿通部１３となっている。 The base portion 11 is installed on the bottom 20a of the storage recess 20 and has a nasal passage insertion portion 13 through which the core material 5 of the leading 4 is inserted. The base portion 11 is formed, for example, in a ring plate shape, and an opening portion inside thereof is a nasal passage insertion portion 13.
取付部１２は、ベース部１１から鼻緒挿通部１３に臨むように延びている。すなわち、取付部１２は、上下方向に見て、リング状のベース部１１の中心位置を通る直径方向に延びている。取付部１２の一端側（基端側）はベース部１１と一体に形成される一方、取付部１２の他端側（先端側）はベース部１１から離隔している。つまり、取付部１２は、基端側でベース部１１と一体になったアーム状に形成されている。 The attachment portion 12 extends from the base portion 11 so as to face the thong insertion portion 13. That is, the attachment portion 12 extends in the diameter direction passing through the center position of the ring-shaped base portion 11 when viewed in the vertical direction. One end side (base end side) of the attachment portion 12 is formed integrally with the base portion 11, while the other end side (tip end side) of the attachment portion 12 is separated from the base portion 11. That is, the attachment portion 12 is formed in an arm shape that is integrated with the base portion 11 on the base end side.
一方、ベース部１１には、取付部１２の先端に対向する領域に溝１４が形成されている。溝１４は、上下方向から見て取付部１２が延びる方向（図３及び図４で左右方向）に延びており、この方向においてベース部１１の幅全体に延びている。そのことにより、取付部１２の先端が上側へ移動したときに、その取付部１２の先端が溝１４内に嵌まり込むことが可能になっている。 On the other hand, a groove 14 is formed in the base portion 11 in a region facing the tip of the mounting portion 12. The groove 14 extends in the direction in which the attachment portion 12 extends (left and right direction in FIGS. 3 and 4) when viewed from the vertical direction, and extends in the entire width of the base portion 11 in this direction. As a result, the tip of the mounting portion 12 can be fitted into the groove 14 when the tip of the mounting portion 12 moves upward.
図２に示すように、取付部１２は、収納凹部２０に収納された状態で、ベース部１１よりも収納凹部２０の開口端側（つまり下側）に配置される。そして、取付部１２には、前壺７側から鼻緒挿通部１３に挿通された先緒４の芯材５が結びつけられて取付けられる。 As shown in FIG. 2, the attachment portion 12 is disposed closer to the opening end side (that is, the lower side) of the storage recess 20 than the base portion 11 in a state of being stored in the storage recess 20. Then, the leading core material 5 inserted through the nasal passage insertion portion 13 from the front wing 7 side is attached to the attachment portion 12 and attached thereto.
そして、本実施形態の鼻緒係止具１０は、取付部１２が弾性を有することにより、この取付部１２に取付られた先緒４の芯材５が台２に対して上下に移動可能になっている。 In the nasal anchor 10 of the present embodiment, the attachment portion 12 has elasticity, so that the core 4 of the leading 4 attached to the attachment portion 12 can move up and down with respect to the base 2. ing.
また、取付部１２は、ベース部１１と反対側（つまり下側）へ突出した湾曲形状を有している。そのことにより、先緒４の芯材５が取付られた取付部１２において、その弾性を効率よく利用することができる。この点で、取付部１２は、円弧状に形成することが好ましい。 Further, the attachment portion 12 has a curved shape protruding to the opposite side (that is, the lower side) from the base portion 11. Thereby, the elasticity can be efficiently used in the attachment portion 12 to which the core material 5 of the first 4 is attached. In this respect, the attachment portion 12 is preferably formed in an arc shape.
さらに、取付部１２には、先緒４の芯材５を取付るための溝１５が形成されている。溝１５は、取付部１２の略中央位置に配置されており、取付部１２の幅方向（図４で上下方向）の全体に延びている。そのことにより、先緒４の芯材５が溝１５内に巻き掛けられるようになっている。 Furthermore, a groove 15 for attaching the first core material 5 is formed in the attachment portion 12. The groove 15 is disposed at a substantially central position of the mounting portion 12 and extends in the entire width direction of the mounting portion 12 (vertical direction in FIG. 4). As a result, the leading core material 5 is wound around the groove 15.
先緒４を台２に係止固定する場合、まず先緒４及び芯材５を台２の上側から前壺７に挿入する。続いて、芯材５を収納凹部２０内へ引き出した上で、鼻緒係止具１０のベース部１１における鼻緒挿通部１３に芯材５を挿通させる。その後、台２の上における先緒４の長さが所定長さになるように調整して、芯材５を取付部１２の略中央位置に結びつける。このとき、芯材５は溝１５内に嵌まり込んで固定される。そして、ベース部１１を収納凹部２０の底２０ａに設置した状態で、収納凹部２０を舌片２２により閉塞する。 When the leading 4 is locked and fixed to the base 2, first, the leading 4 and the core material 5 are inserted into the front collar 7 from the upper side of the base 2. Subsequently, after the core material 5 is drawn into the housing recess 20, the core material 5 is inserted through the umbilical cord insertion portion 13 in the base portion 11 of the umbilical cord locking tool 10. Thereafter, the length of the forehead 4 on the base 2 is adjusted to be a predetermined length, and the core material 5 is tied to the substantially central position of the mounting portion 12. At this time, the core material 5 is fitted into the groove 15 and fixed. Then, in a state where the base portion 11 is installed on the bottom 20 a of the storage recess 20, the storage recess 20 is closed by the tongue piece 22.
使用者が草履１を履いて歩くとき、鼻緒３は台２に対して上下に動こうとする足を押さえ込む。一般の鼻緒３では、台２の上における先緒４の長さが一定に固定されているので、先緒４が足に強く擦れてしまう結果、足が痛くなり易い。 When the user walks while wearing sandals 1, the umbilical cord 3 presses the foot that moves up and down with respect to the table 2. In the general umbilical cord 3, since the length of the forehead 4 on the table 2 is fixed, the forehead 4 rubs strongly against the foot, so that the foot is likely to hurt.
これに対し、本実施形態の鼻緒係止具１０は、その取付部１２が弾性を有しており上下に弾性変形可能な構成となっている。そのため、この取付部１２に取付られた先緒４及び芯材５は、鼻緒３が台２に取付られた後であっても、台２に対して上下に移動することができる。すなわち、本実施形態の鼻緒係止具１０は、台２の上における先緒４の長さを、足の動きに応じて変化させることができるのである。 On the other hand, the umbilical cord anchor 10 of the present embodiment has a configuration in which the mounting portion 12 has elasticity and can be elastically deformed up and down. Therefore, the forehead 4 and the core material 5 attached to the attachment portion 12 can move up and down with respect to the table 2 even after the nose cord 3 is attached to the table 2. That is, the umbilical cord anchoring device 10 of the present embodiment can change the length of the forehead 4 on the table 2 according to the movement of the foot.
このように、本実施形態によると、台２上の足の動きに追従して先緒４を上下に移動させることができるので、先緒４に当たる足の痛みを大幅に抑制することができる。そのことに加え、鼻緒３を足に適度にフィットさせた状態で足の動きに追従させることができるので、草履１の装着感を高めることができる。 Thus, according to the present embodiment, the forehead 4 can be moved up and down following the movement of the foot on the table 2, so that the pain in the foot hitting the forehead 4 can be greatly suppressed. In addition, since the movement of the foot can be followed in a state where the umbilical cord 3 is appropriately fitted to the foot, the wearing feeling of the sandals 1 can be enhanced.
ここで、図５を参照して取付部１２の作用について詳しく説明する。図５では、先緒４及び芯材５の図示を省略している。足の動きによって先緒４及び芯材５が引き上げられる場合、まず図５で矢印Ａに示すように、取付部１２は、その基端を中心に弾性変形して上側へ移動する。その後、取付部１２の先端がベース部１１の溝１４内に嵌まり込む。この状態で、さらに先緒４及び芯材５が引き上げられると、図５で矢印Ｂに示すように、取付部１２の先端が溝１４に沿って側方へ移動しつつ、取付部１２の全体が弾性変形して上側に移動することとなる。 Here, with reference to FIG. 5, the effect | action of the attaching part 12 is demonstrated in detail. In FIG. 5, the leading 4 and the core material 5 are not shown. When the forehead 4 and the core material 5 are pulled up by the movement of the foot, first, as shown by an arrow A in FIG. 5, the attachment portion 12 is elastically deformed around its base end and moves upward. Thereafter, the tip of the attachment portion 12 is fitted into the groove 14 of the base portion 11. In this state, when the forehead 4 and the core member 5 are further pulled up, as shown by an arrow B in FIG. 5, the tip of the attachment portion 12 moves sideways along the groove 14, and the entire attachment portion 12 is moved. Is elastically deformed and moves upward.
このように、ベース部１１に溝１４を設けることにより、その溝深さ分だけ取付部１２を上側（Ａ方向）へ移動させ易くすることができると共に、取付部１２の先端が溝１４に沿って側方（Ｂ方向）へ移動することにより取付部１２を上側（Ａ方向）へ移動させ易くすることができる。その結果、先緒４を上側に移動させ易くなる。 Thus, by providing the groove 14 in the base portion 11, the attachment portion 12 can be easily moved upward (direction A) by the depth of the groove, and the tip of the attachment portion 12 extends along the groove 14. Thus, the mounting portion 12 can be easily moved upward (A direction) by moving sideward (B direction). As a result, it becomes easier to move the forehead 4 upward.
また、本実施形態の鼻緒係止具１０は、その取付部１２を湾曲形状としたので、その全体の弾性を効率よく利用して先緒４を好適に上下移動させることができる。さらに、取付部１２の溝１５に先緒４の芯材５を嵌まり込んだ状態で取付ることができるので、芯材５の取付位置のずれを防止できる。よって、先緒４の芯材５を取付部１２に対して確実に取付固定することができる。 Moreover, since the attachment part 12 made the curved shape the nasal anchor 10 of this embodiment, the front 4 can be suitably moved up and down efficiently using the whole elasticity efficiently. Furthermore, since it can be attached in a state in which the leading core material 5 is fitted in the groove 15 of the attachment portion 12, it is possible to prevent the attachment position of the core material 5 from being displaced. Therefore, the leading core material 5 can be securely fixed to the attachment portion 12.
ところで、本発明とは異なる他の鼻緒係止具の例として、例えば、収納凹部２０内に配置されるバネ部品（図示省略）と、このバネ部品の両端に設けられたワッシャ部品（図示省略）と、バネ部品及びワッシャ部品に挿通された先緒４の芯材５を固定する固定部品（図示省略）とを備えた構成が考えられる。この構成によっても、バネ部品が伸縮することにより先緒４を上下移動させることが可能である。 By the way, as another example of the cord anchor different from the present invention, for example, a spring part (not shown) disposed in the housing recess 20 and washer parts (not shown) provided at both ends of the spring part. And the structure provided with the fixing | fixed part (illustration omitted) which fixes the core material 5 of the front 4 inserted by the spring component and the washer part can be considered. Also with this configuration, the forehead 4 can be moved up and down by the expansion and contraction of the spring component.
しかし、バネ部品は最も縮んだ状態であってもある程度の厚みを有する一方、他のワッシャ部品及び固定部品は不変で一定の厚みを有するので、この鼻緒係止具は、所定の伸縮量を維持しつつ全体の厚みを小さくすることが難しい。この点について詳述すると、当該他の鼻緒係止具は、複数の部品（固定部品、バネ部品及びワッシャ部品）からなり、その複数の部品のうちの一部の部品（バネ部品）のみが鼻緒係止具全体の伸縮に寄与するだけである。すなわち、当該他の鼻緒係止具は、全体の厚みに対する伸縮率が低い。よって、先緒４の移動量を所定量確保するためには、バネ部品の自然長での厚みを比較的大きくする必要があり、バネ部品以外の部品の厚みを加えた全体の厚みも比較的大きくならざるを得ない。 However, the spring parts have a certain thickness even in the most contracted state, while the other washer parts and fixing parts have a constant and constant thickness. However, it is difficult to reduce the overall thickness. This point will be described in detail. The other umbilical cord locking device is composed of a plurality of parts (fixing parts, spring parts, and washer parts), and only a part of the plurality of parts (spring parts) is kinked. It only contributes to the expansion and contraction of the entire locking tool. That is, the other umbilical cord locking device has a low expansion / contraction rate with respect to the entire thickness. Therefore, in order to secure the predetermined amount of movement of the first 4, it is necessary to relatively increase the thickness of the spring component in the natural length, and the total thickness including the thickness of components other than the spring component is also relatively It must be large.
これに対し、本実施形態の鼻緒係止具１０は、全体が一体に形成された単一の部品からなり、その単一部品自体が弾性変形可能になっているので、上記他の鼻緒係止具に比べて全体の厚みに対する伸縮率がよい。したがって、先緒４の移動量を所定量確保するために必要な鼻緒係止具１０全体の厚みは、上記他の鼻緒係止具よりも小さくてすむ。 On the other hand, the umbilical cord locking tool 10 of the present embodiment is composed of a single part formed as a whole, and the single part itself is elastically deformable. The expansion / contraction rate with respect to the overall thickness is better than the tool. Therefore, the thickness of the entire umbilical cord locking device 10 necessary for securing a predetermined amount of movement of the leading edge 4 can be smaller than that of the other lanyard locking device.
そのため、本実施形態では、先緒４の移動量を確保しつつ、鼻緒係止具１０を収納する収納凹部２０の深さ（つまり、台２の底から収納凹部２０の底２０ａまでの深さ）を比較的浅くすることができる。よって、本実施形態の鼻緒係止具１０によれば、台２の厚みが比較的薄い履物であっても、先緒４を十分な量で上下に移動させることができる。そのことに加え、鼻緒係止具１０は単一部品からなるので、複数の部品からなる他の鼻緒係止具に比べて製品コストや組立コストを大幅に低減することができる。
（その他の実施形態）
Therefore, in the present embodiment, the depth of the storage recess 20 for storing the umbilical cord locking device 10 (that is, the depth from the bottom of the table 2 to the bottom 20a of the storage recess 20 is ensured while securing the amount of movement of the leading 4. ) Can be made relatively shallow. Therefore, according to the umbilical cord locking tool 10 of the present embodiment, even when the footwear 2 is relatively thin, the forehead 4 can be moved up and down by a sufficient amount. In addition, since the umbilical cord anchoring device 10 is composed of a single part, the product cost and assembly cost can be greatly reduced as compared with other umbilical cord anchoring devices composed of a plurality of parts.
(Other embodiments)
以上の説明では、鼻緒係止具１０の取付部１２が湾曲形状とした例について説明したが、取付部１２はこれに限らず他の形状であってもよい。例えば、鼻緒係止具１０の側面図である図６に示すように、上記と同様にリング板状のベース部１１の一部から斜め下方に延びて鼻緒挿通部１３に臨むようなアーム形状としてもよい。この場合も取付部１２に溝１５を形成することが望ましい。このようにしても、取付部１２をその基端を中心に弾性変形させて先緒４を上下に移動させることができる。 In the above description, the example in which the attachment portion 12 of the umbilical cord anchoring tool 10 has a curved shape has been described, but the attachment portion 12 is not limited to this and may have another shape. For example, as shown in FIG. 6, which is a side view of the umbilical cord anchoring device 10, an arm shape that extends obliquely downward from a part of the ring plate-like base portion 11 and faces the umbilical cord insertion portion 13 as described above. Also good. Also in this case, it is desirable to form the groove 15 in the mounting portion 12. Even in this case, the attachment portion 12 can be elastically deformed around its base end, and the forehead 4 can be moved up and down.
また、鼻緒係止具１０のベース部１１をリング板状に形成した例について説明したが、これに限らず、他の形状であってもよい。例えば、鼻緒係止具１０の底面図である図７に示すように、ベース部１１をリングの一部が欠けたＣ字状の形状としてもよい。この構成にすると、取付部１２が弾性変形して上側に移動する際に、ベース部１１の一対の端部１１ａも互いに離隔する方向に弾性変形して移動するので、鼻緒係止具１０の全体を弾性変形させ易くすることができる。なお、ベース部１１の剛性を高めるという観点では、ベース部１１をリング状に形成することが好ましい。 Moreover, although the example which formed the base part 11 of the umbilical cord locking tool 10 in the ring plate shape was demonstrated, not only this but another shape may be sufficient. For example, as shown in FIG. 7, which is a bottom view of the umbilical cord anchoring device 10, the base portion 11 may have a C shape with a part of the ring missing. With this configuration, when the attachment portion 12 is elastically deformed and moves upward, the pair of end portions 11a of the base portion 11 are also elastically deformed and moved in directions away from each other. Can be easily elastically deformed. In addition, it is preferable to form the base part 11 in a ring shape from the viewpoint of increasing the rigidity of the base part 11.
また、上記の説明では、取付部１２をその先端がベース部１１から離隔したアーム状である例について説明したが、これに限らず、取付部１２の両端がベース部１１と一体になったアーチ状の形成することも可能である。ただし、取付部１２を弾性変形させ易くする観点では、上述のようなアーム状とすることが望ましい。また、取付部１２アーム状としておけば、芯材５の結び目を解かない状態で、芯材５を取付部１２の先端から着脱することも可能であるため、鼻緒３を交換し易くなる利点もある。 Further, in the above description, the example in which the mounting portion 12 has an arm shape whose tip is separated from the base portion 11 is described. However, the present invention is not limited to this, and the arch in which both ends of the mounting portion 12 are integrated with the base portion 11. It is also possible to form a shape. However, from the viewpoint of facilitating elastic deformation of the attachment portion 12, it is desirable to have the above-described arm shape. Further, if the attachment portion 12 is in the form of an arm, the core material 5 can be attached and detached from the tip of the attachment portion 12 in a state where the knot of the core material 5 is not released, so that there is also an advantage that the nasal cord 3 can be easily replaced. is there.
また、上述の実施形態では、先緒４の芯材５を鼻緒係止具１０により係止した例について説明したが、さらに後緒６の芯材５についても鼻緒係止具１０によって係止してもよい。すなわち、図示は省略するが、この場合も同様に、台２の孔８に連通する収納凹部に鼻緒係止具１０を収納し、先緒４の芯材５と同様に後緒６の芯材５を取付部１２に結びつけて固定すればよい。このように、先緒４及び後緒６の各端部をそれぞれ鼻緒係止具１０により台２に係止固定すれば、鼻緒３を足の動きにより追従させることができる。その結果、足の痛みをより抑制し、草履１の装着感をさらに高めることが可能になる。 In the above-described embodiment, the example in which the core material 5 at the beginning 4 is locked by the cord anchor 10 has been described, but the core material 5 at the beginning 6 is also locked by the cord anchor 10. May be. That is, although not shown, similarly, in this case as well, the nasal anchor 10 is stored in the storage recess communicating with the hole 8 of the base 2, and the core material of the back 6 is stored in the same manner as the core 5 of the front 4. What is necessary is just to tie 5 to the attaching part 12 and to fix. In this way, if the end portions of the leading 4 and the trailing 6 are respectively locked and fixed to the table 2 by the strap anchor 10, the strap 3 can be followed by the movement of the foot. As a result, foot pain can be further suppressed, and the wearing feeling of sandals 1 can be further enhanced.
なお、上記実施形態では、鼻緒係止具１０が取付られる履物として草履１を例に挙げて説明したが、本発明はこれに限らず、例えばサンダルや下駄等の鼻緒を有する他の履物についても同様に適用できる。 In the above embodiment, the sandals 1 have been described as an example of the footwear to which the umbilical cord anchoring device 10 is attached. However, the present invention is not limited to this, and for example, other footwear having a lanyard such as sandals and clogs. The same applies.
以上説明したように、本発明は、鼻緒を草履等の履物の台に係止するための鼻緒係止具及びそれを備えた履物について有用である。 As described above, the present invention is useful for a cord anchor for locking a cord to a footwear platform such as sandals and footwear including the same.
