ところで、ライフジャケットなどの救命胴衣や、リュックサックなどの背負袋の装着品は、身体の腰部に装着されるベルトと同じく、複数の帯体を備えている。これらの帯体もまた、装着品の位置や装着品のサイズを装着者の身体に合わせるために、余剰となる部分を備えている。そして、余剰となる帯体は、装着品を利用する利用者の安全性を高める観点から、他の帯体や装着品の本体などに束ねて固定することが求められる。一方、上記装着品が使用されるシーンのなかには、例えば、片手に釣り竿を持っているフィッシング時、片手にステッキを持っている登山時、視界が良好ではない夜間や早朝などが含まれる。それゆえに、上記固定具には、片手での固定の操作、片手での解除の操作、視界が良好ではない環境での操作などの新たな利用のシーンに適した操作性が望まれている。
本発明の目的は、操作性の拡張を可能とした樹脂製固定具を提供することである。 By the way, life jackets such as life jackets and backpacks such as rucksacks are provided with a plurality of belts like a belt worn on the waist of the body. These bands also have extra parts to fit the position of the wearer and the size of the wearer to the wearer's body. Then, the surplus band is required to be bundled and fixed to another band or the main body of the wear from the viewpoint of enhancing the safety of the user who uses the wear. On the other hand, the scenes in which the above-mentioned attached items are used include, for example, fishing with a fishing rod in one hand, mountain climbing with a walking stick in one hand, nighttime and early morning when the visibility is not good. Therefore, the fixture is desired to have operability suitable for new usage scenes such as one-handed fixing operation, one-handed releasing operation, and operation in an environment where visibility is not good.
An object of the present invention is to provide a resin fixture capable of expanding operability.

上記課題を解決するための樹脂製固定具は、一方向に延びる基体内面を有した板状の基体片と、一方向に延びる係止内面を有した係止本体部を備える板状の係止片と、前記基体片の一端と前記係止片の一端とを連結し、前記基体内面と前記係止内面とを相互に対向させる挟持状態と、前記基体内面上を開放する解除状態とを有するヒンジ部と、を備える樹脂製固定具である。前記挟持状態での前記樹脂製固定具の外側が、前記各片の外側であり、前記挟持状態での前記樹脂製固定具の内側が、前記各片の内側であり、前記基体片の前記一方向の長さは、前記係止片の前記一方向の長さよりも短い。前記基体片は、前記一方向の他端に、爪部と爪誘導部とを備え、前記爪部は、前記基体片の他端で前記一方向に突き出ており、前記爪誘導部は、前記爪部の内側に位置し、前記爪部から前記基体片の一端に向けて徐々に内側に変位する傾きを有した誘導斜面を備える。前記係止片は、前記一方向の他端に位置し、前記係止本体部の端を内側で覆う半ドーム状を有した爪受け部を備え、前記爪受け部の縁と前記係止内面とが、前記係止片の一端に向く開口部を構成し、前記解除状態から前記挟持状態への遷移の際に、前記爪受け部の縁と前記誘導斜面とが対向し、前記爪受け部の縁に対する前記誘導斜面の押圧によって前記爪部が前記開口部内に誘導される。 The resin fixture for solving the above problems is a plate-shaped locking having a plate-shaped substrate piece having a substrate inner surface extending in one direction and a locking main body portion having a locking inner surface extending in one direction. It has a sandwiching state in which one end of the substrate piece and one end of the locking piece and one end of the locking piece are connected so that the inner surface of the substrate and the inner surface of the locking are opposed to each other, and a release state in which the inner surface of the substrate is opened. A resin fixture provided with a hinge portion. The outside of the resin fixture in the sandwiched state is the outside of each piece, the inside of the resin fixture in the sandwiched state is the inside of each piece, and the one of the substrate pieces. The length in the direction is shorter than the length in the one direction of the locking piece. The base piece is provided with a claw portion and a claw guide portion at the other end in the one direction, the claw portion protrudes in the one direction at the other end of the base piece, and the claw guide portion is said. The guide slope is located inside the claw portion and has an inclination that gradually displaces inward from the claw portion toward one end of the substrate piece. The locking piece is located at the other end in the one direction, and includes a claw receiving portion having a semi-dome shape that covers the end of the locking main body portion inside, and the edge of the claw receiving portion and the locking inner surface. Abuts an opening facing one end of the locking piece, and at the time of transition from the released state to the holding state, the edge of the claw receiving portion and the guiding slope face each other, and the claw receiving portion The claw portion is guided into the opening by pressing the guide slope against the edge of the dome.

上記構成によれば、基体片と係止片とによって対象が樹脂製固定具に固定されるとき、まず、基体内面と係止内面とが相互に対向するようにヒンジ部が折り曲げられる。次いで、開口部内に爪部が入るまで、誘導斜面の押圧が爪受け部の縁を変形させ、また、押圧による反力で係止片が反るように曲がる。そして、誘導斜面が爪受け部の縁を通過して、爪部が開口部内に入る。この際、反るように曲がっていた係止片や、誘導斜面に押圧されていた爪受け部の縁が、元の形状に戻り、形状が戻る際の振動によって音が発生する。結果として、解除状態から挟持状態への遷移に際し、爪部が開口部内に入るように、爪部と開口部とを爪誘導部が誘導する。そのため、基体片に係止片を係止させる操作を、片手によるヒンジ部の折り畳みによって利用者は実現できる。さらに、挟持状態への遷移の完了時に音が発生するため、挟持状態への遷移の完了を利用者は音によって認識できる。それゆえに、暗所での利用のシーンや、片手での利用のシーンに適した操作性を樹脂製固定具に付与することが可能となる。 According to the above configuration, when the object is fixed to the resin fixture by the substrate piece and the locking piece, the hinge portion is first bent so that the inner surface of the substrate and the inner surface of the locking face face each other. Next, until the claw portion enters the opening, the pressing of the induction slope deforms the edge of the claw receiving portion, and the reaction force due to the pressing bends the locking piece so as to warp. Then, the guide slope passes through the edge of the claw receiving portion, and the claw portion enters the opening. At this time, the locking piece bent so as to warp and the edge of the claw receiving portion pressed against the guide slope return to the original shape, and sound is generated by the vibration when the shape returns. As a result, at the transition from the released state to the pinched state, the claw guiding portion guides the claw portion and the opening so that the claw portion enters the opening. Therefore, the operation of locking the locking piece to the substrate piece can be realized by the user by folding the hinge portion with one hand. Further, since a sound is generated when the transition to the pinch state is completed, the user can recognize the completion of the transition to the pinch state by the sound. Therefore, it is possible to provide the resin fixture with operability suitable for a scene of use in a dark place or a scene of use with one hand.

上記樹脂製固定具において、前記係止本体部は、前記係止本体部の前記端を内側から外側まで貫通する発音孔をさらに備え、前記爪受け部は、前記発音孔を内側から覆ってもよい。この樹脂製固定具によれば、係止本体部の発音孔を半ドーム状の爪受け部が覆うため、挟持状態への遷移の完了時に発生する音が共鳴によって増幅される。 In the resin fixture, the locking body further includes a sounding hole that penetrates the end of the locking body from the inside to the outside, and the claw receiving part covers the sounding hole from the inside. Good. According to this resin fixture, since the sounding hole of the locking main body is covered with the semi-dome-shaped claw receiving portion, the sound generated at the completion of the transition to the pinching state is amplified by resonance.

上記樹脂製固定具において、前記係止片は、前記係止片の一端および他端よりも厚みが薄い反り部を前記係止片の一端と他端との間に備えてもよい。この樹脂製固定具によれば、誘導斜面の押圧による反力が係止片に作用する際に、反り部を起点として係止片が反りやすくなる。 In the resin fixture, the locking piece may be provided with a warped portion thinner than one end and the other end of the locking piece between one end and the other end of the locking piece. According to this resin fixture, when the reaction force due to the pressing of the induction slope acts on the locking piece, the locking piece tends to warp starting from the warped portion.

上記樹脂製固定具において、前記爪受け部の縁は、前記誘導斜面を受け入れ可能な窪みを備えてもよい。この樹脂製固定具によれば、誘導斜面が爪受け部の窪みに受け入れられた状態で、爪誘導部の誘導斜面が爪受け部の縁を押圧する。結果として、爪受け部の縁を誘導斜面が押圧するときに、爪受け部の縁と、誘導斜面との相対的な位置のずれが抑えられる。そのため、誘導斜面の押圧による開口部の変形、ひいては、解除状態から挟持状態への遷移が円滑に行われる。 In the resin fixture, the edge of the claw receiving portion may be provided with a recess capable of accepting the guide slope. According to this resin fixture, the guiding slope of the nail guiding portion presses the edge of the nail receiving portion in a state where the guiding slope is received by the recess of the nail receiving portion. As a result, when the guide slope presses the edge of the nail receiving portion, the relative positional deviation between the edge of the nail receiving portion and the guide slope is suppressed. Therefore, the deformation of the opening due to the pressing of the induction slope, and the transition from the released state to the pinched state are smoothly performed.

上記樹脂製固定具において、前記基体片は、前記基体内面とは反対側の面である基体外面に、前記樹脂製固定具の利用者が触覚で認識可能な段差を有した段差部を備えてもよい。この樹脂製固定具によれば、基体内面と基体外面との差異を利用者は触覚で認識することが可能ともなるため、視界が良好ではないシーンでの対象の固定操作や固定の解除操作が円滑に行われる。 In the resin fixture, the substrate piece is provided with a step portion having a step portion that is tactilely recognizable by the user of the resin fixture on the outer surface of the substrate, which is a surface opposite to the inner surface of the substrate. May be good. According to this resin fixture, the user can visually recognize the difference between the inner surface of the substrate and the outer surface of the substrate, so that the target can be fixed or released in a scene where the visibility is not good. It will be done smoothly.

本発明によれば、樹脂製固定具の操作性を拡張することが可能となる。 According to the present invention, it is possible to extend the operability of the resin fixture.

The resin fixing portion is a resin product in which the base piece 10, the locking piece 20, and the hinge portion 30 are integrally molded. The hinge portion 30 connects the base end E1B, which is one end of the substrate piece 10, and the base end E2B, which is one end of the locking piece 20. The substrate piece 10 and the locking piece 20 extend in a common direction.

以下では、基体片１０および係止片２０の延びる方向が長手方向であり、長手方向と直交する方向が幅方向である。基体片１０と係止片２０とが長手方向に並ぶ状態は、ヒンジ部３０の解除状態であり、基体片１０と係止片２０とが相互に対向する状態は、ヒンジ部３０の挟持状態である。挟持状態での樹脂製固定具の外表面に対する外側が、基体片１０および係止片２０の外側であり、挟持状態での樹脂製固定具の外表面に対する内側が、基体片１０および係止片２０の内側である。 In the following, the extending direction of the substrate piece 10 and the locking piece 20 is the longitudinal direction, and the direction orthogonal to the longitudinal direction is the width direction. The state in which the base piece 10 and the locking piece 20 are lined up in the longitudinal direction is the state in which the hinge portion 30 is released, and the state in which the base piece 10 and the locking piece 20 are opposed to each other is the state in which the hinge portion 30 is sandwiched. is there. The outside of the resin fixture in the sandwiched state with respect to the outer surface is the outside of the substrate piece 10 and the locking piece 20, and the inside of the resin fixture in the sandwiched state with respect to the outer surface is the substrate piece 10 and the locking piece 20. It is inside 20.

基体片１０は、基体本体部１０Ｂと係止歯１１とを備える。基体本体部１０Ｂは、長手方向に延びる板状であり、かつ、基体本体部１０Ｂの周縁を基体本体部１０Ｂの中央よりも反り上げる曲板状を有する。基体本体部１０Ｂは、挟持状態での係止片２０と対向する凹曲面として基体内面１０Ｓを備える。 The substrate piece 10 includes a substrate main body 10B and locking teeth 11. The base body 10B has a plate shape extending in the longitudinal direction and has a curved plate shape in which the peripheral edge of the base body 10B is warped from the center of the base body 10B. The base body 10B includes a base inner surface 10S as a concave curved surface facing the locking piece 20 in the sandwiched state.

係止歯１１は、基体内面１０Ｓから内側（図１の上側）に向けて立設されている。係止歯１１は、長手方向において、基体本体部１０Ｂのほぼ全体に延びる板状を有する。係止歯１１の内側端面（図１の上端面）は、長手方向に延びる波状を有している。係止歯１１の各歯先は、各歯において、係止歯１１の長手方向のほぼ中央に偏っている。 The locking teeth 11 are erected from the inner surface 10S of the substrate toward the inside (upper side in FIG. 1). The locking teeth 11 have a plate shape extending substantially over the base body 10B in the longitudinal direction. The inner end surface (upper end surface of FIG. 1) of the locking tooth 11 has a wavy shape extending in the longitudinal direction. Each tooth tip of the locking tooth 11 is biased to substantially the center of the locking tooth 11 in the longitudinal direction in each tooth.

基体片１０の他端部である先端Ｅ１Ｔは、長手方向に突き出る爪部１３と、爪部１３から基体内面１０Ｓにわたり立設された爪誘導部１２とを備える。爪部１３は、基体片１０の先端Ｅ１Ｔから外側（図１の下側）に湾曲するフック状の断面を幅方向に連続させている。爪部１３は、挟持状態において係止片２０に引っ掛かる引っ掛かり部として機能する。 The tip E1T, which is the other end of the substrate piece 10, includes a claw portion 13 protruding in the longitudinal direction and a claw guiding portion 12 erected from the claw portion 13 to the inner surface 10S of the substrate. The claw portion 13 has a hook-shaped cross section curved outward (lower side in FIG. 1) from the tip E1T of the substrate piece 10 continuous in the width direction. The claw portion 13 functions as a hooking portion that is hooked on the locking piece 20 in the pinched state.

爪誘導部１２は、係止歯１１よりも先端Ｅ１Ｔの側に位置し、かつ、爪部１３の内側（図１の上側）に位置する。爪誘導部１２は、係止歯１１と連なるように、係止歯１１から先端Ｅ１Ｔまで長手方向に延びる。爪誘導部１２の内側端面（図１の上端面）は、誘導斜面である。誘導斜面は、緩やかな曲面であり、先端Ｅ１Ｔから基端Ｅ１Ｂに向けて徐々に内側（図１の上側）に変位する傾きを有する。 The claw guide portion 12 is located closer to the tip E1T than the locking tooth 11, and is located inside the claw portion 13 (upper side in FIG. 1). The claw guide portion 12 extends in the longitudinal direction from the locking tooth 11 to the tip E1T so as to be connected to the locking tooth 11. The inner end surface (upper end surface in FIG. 1) of the claw guide portion 12 is a guide slope. The induction slope is a gentle curved surface and has a slope that gradually displaces inward (upper side in FIG. 1) from the tip E1T toward the base end E1B.

係止片２０は、係止本体部２０Ｂと爪受け部２４とを備える。係止本体部２０Ｂは、長手方向に延びる板状であり、かつ、基体本体部１０Ｂと同じく、係止本体部２０Ｂの周縁を係止本体部２０Ｂの中央よりも反り上がる曲板状を有する。係止本体部２０Ｂは、挟持状態での基体片１０と対向する凹曲面として係止内面２０Ｓを備える。 The locking piece 20 includes a locking main body portion 20B and a claw receiving portion 24. The locking main body 20B has a plate shape extending in the longitudinal direction and, like the base main body 10B, has a curved plate shape in which the peripheral edge of the locking main body 20B is warped from the center of the locking main body 20B. The locking body portion 20B includes a locking inner surface 20S as a concave curved surface facing the substrate piece 10 in the sandwiched state.

係止本体部２０Ｂは、長手方向のほぼ中央に反り部２１を備える。反り部２１の幅方向の長さは、係止本体部２０Ｂのなかで、反り部２１以外の他の部位よりも小さい。係止片２０は、反り部２１を起点として反りやすい形状を有する。また、係止片２０は、長手方向のほぼ中央に、長手方向に延びる貫通孔２２を備える。貫通孔２２は、幅方向における反り部２１の厚みを、係止片２０の基端Ｅ２Ｂや先端Ｅ２Ｔよりも薄くし、それによって、反り部２１を起点として係止片２０をさらに反りやすくする。なお、反り部２１の位置する範囲は、係止片２０の長手方向の長さを１００％としたとき、係止片２０の長手方向の中央から長手方向の両方向にそれぞれ２０％以内であることが好ましい。 The locking body portion 20B includes a warped portion 21 substantially at the center in the longitudinal direction. The length of the warped portion 21 in the width direction is smaller than that of the locking main body portion 20B other than the warped portion 21. The locking piece 20 has a shape that easily warps from the warped portion 21 as a starting point. Further, the locking piece 20 is provided with a through hole 22 extending in the longitudinal direction at substantially the center in the longitudinal direction. The through hole 22 makes the thickness of the warped portion 21 in the width direction thinner than the base end E2B and the tip end E2T of the locking piece 20, thereby making the locking piece 20 more easily warped starting from the warped portion 21. The range in which the warped portion 21 is located is within 20% in both the longitudinal direction from the center of the locking piece 20 in the longitudinal direction, assuming that the length of the locking piece 20 in the longitudinal direction is 100%. Is preferable.

係止本体部２０Ｂは、係止内面２０Ｓの先端Ｅ２Ｔの側に、係止本体部２０Ｂの内側から外側まで（図１の上側から下側まで）を貫通する発音孔２３を備える。発音孔２３は、幅方向において、係止本体部２０Ｂのほぼ全体にわたり、爪受け部２４によって覆われている。 The locking main body 20B is provided with a sounding hole 23 penetrating from the inside to the outside (from the upper side to the lower side in FIG. 1) of the locking main body 20B on the side of the tip E2T of the locking inner surface 20S. The sounding hole 23 is covered by the claw receiving portion 24 over substantially the entire locking main body portion 20B in the width direction.

爪受け部２４は、係止本体部２０Ｂの周縁のなかで、係止本体部２０Ｂの一端における縁と連結した半ドーム状を有する。係止内面２０Ｓと対向する方向から見て、爪受け部２４は、発音孔２３の一部を覆う。爪受け部２４における基端Ｅ２Ｂ側の縁２４Ｅと、係止内面２０Ｓにおける先端Ｅ２Ｔ側の縁とは、係止片２０の基端Ｅ２Ｂに向く開口部を構成する。幅方向において、爪受け部２４の縁２４Ｅの有する長さは、爪部１３の有する長さよりも大きい。爪受け部２４の縁２４Ｅは、挟持状態への遷移において、爪部１３が開口部に入ること、および、爪部１３の先端である引っ掛かり部が爪受け部２４の縁２４Ｅに引っ掛かることを可能としている。 The claw receiving portion 24 has a semi-dome shape connected to an edge at one end of the locking main body 20B in the peripheral edge of the locking main body 20B. The claw receiving portion 24 covers a part of the sounding hole 23 when viewed from the direction facing the locking inner surface 20S. The edge 24E on the base end E2B side of the claw receiving portion 24 and the edge on the tip end E2T side of the locking inner surface 20S form an opening facing the base end E2B of the locking piece 20. In the width direction, the length of the edge 24E of the claw receiving portion 24 is larger than the length of the claw portion 13. The edge 24E of the claw receiving portion 24 can allow the claw portion 13 to enter the opening and the hooking portion at the tip of the claw portion 13 to be hooked on the edge 24E of the claw receiving portion 24 in the transition to the pinching state.

爪受け部２４の内側面（図１の上面）は、複数の突起２５を備える。各突起２５は、段差部の一例であり、樹脂製固定具を利用する利用者が各突起２５の存在を触覚で認識可能な段差を有する。複数の突起２５は、係止片２０のなかの爪受け部２４の位置を触覚によって利用者に認識させる。 The inner side surface (upper surface of FIG. 1) of the claw receiving portion 24 includes a plurality of protrusions 25. Each protrusion 25 is an example of a stepped portion, and has a stepped portion in which a user using a resin fixture can tactilely recognize the existence of each protrusion 25. The plurality of protrusions 25 make the user recognize the position of the claw receiving portion 24 in the locking piece 20 by tactile sensation.

爪受け部２４の縁２４Ｅは、爪誘導部１２の誘導斜面を受け入れ可能な窪み２６を備える。窪み２６の深さは、爪受け部２４の縁２４Ｅから先端Ｅ２Ｔに向けて徐々に浅くなる。挟持状態への遷移において、窪み２６は、窪み２６への爪誘導部１２の進入を促し、爪誘導部１２の誘導斜面と、爪受け部２４の縁２４Ｅとの相対的な位置のずれを抑える。 The edge 24E of the claw receiving portion 24 includes a recess 26 capable of receiving the guiding slope of the claw guiding portion 12. The depth of the recess 26 gradually becomes shallower from the edge 24E of the nail receiving portion 24 toward the tip E2T. In the transition to the pinched state, the recess 26 promotes the entry of the claw guiding portion 12 into the recess 26, and suppresses the relative positional deviation between the guiding slope of the claw guiding portion 12 and the edge 24E of the claw receiving portion 24. ..

図２が示すように、基体片１０の先端Ｅ１Ｔにおける外面（図２の下面）は、複数の突起１４を備える。複数の突起１４は、段差部の一例であり、突起２５と同じく、樹脂製固定具を利用する利用者が突起２５の存在を触覚で認識可能な段差を有する。複数の突起１４は、基体片１０のなかの先端Ｅ１Ｔの位置、特に、基体片１０のなかの爪部１３の位置を触覚によって利用者に認識させる。また、複数の突起１４は、挟持状態への遷移において、利用者の指などの基体片１０の外面での滑りを抑える。 As shown in FIG. 2, the outer surface (lower surface of FIG. 2) of the tip E1T of the substrate piece 10 includes a plurality of protrusions 14. The plurality of protrusions 14 are examples of stepped portions, and like the protrusions 25, the plurality of protrusions 14 have steps that allow the user using the resin fixture to recognize the presence of the protrusions 25 by touch. The plurality of protrusions 14 make the user recognize the position of the tip E1T in the substrate piece 10, particularly the position of the claw portion 13 in the substrate piece 10 by tactile sensation. Further, the plurality of protrusions 14 suppress slippage on the outer surface of the substrate piece 10 such as a user's finger in the transition to the pinched state.

係止本体部２０Ｂの外面（図２の下面）は、貫通孔２２よりも基端Ｅ２Ｂの側に、表示部２７を備える。表示部２７は、樹脂製固定具の製品名や、樹脂製固定具の製品番号などの表示に用いられる。なお、反り部２１の位置する範囲、すなわち、貫通孔２２の位置する範囲が、上述した好ましい範囲内であれば、表示部２７の大きさを係止本体部２０Ｂの外面で十分に確保することが可能ともなる。 The outer surface (lower surface of FIG. 2) of the locking main body 20B is provided with a display 27 on the base end E2B side of the through hole 22. The display unit 27 is used to display the product name of the resin fixture, the product number of the resin fixture, and the like. If the range where the warped portion 21 is located, that is, the range where the through hole 22 is located is within the above-mentioned preferable range, the size of the display portion 27 should be sufficiently secured on the outer surface of the locking main body portion 20B. Is also possible.

係止本体部２０Ｂの外面は、貫通孔２２よりも先端Ｅ２Ｔ側に、複数の突起２８を備える。複数の突起２８は、段差部の一例であり、突起１４，２５と同じく、樹脂製固定具を利用する利用者が突起２８の存在を触覚で認識可能な段差を有する。複数の突起２８は、係止本体部２０Ｂの先端Ｅ２Ｔの位置、特に、挟持状態において突起１４と対向する位置を触覚によって利用者に認識させる。複数の突起２８は、挟持状態への遷移において、利用者の指などの係止片２０の外面での滑りを抑える。 The outer surface of the locking main body 20B is provided with a plurality of protrusions 28 on the tip E2T side of the through hole 22. The plurality of protrusions 28 are examples of the stepped portions, and like the protrusions 14 and 25, the plurality of protrusions 28 have a stepped portion that allows the user using the resin fixture to tactilely recognize the existence of the protrusions 28. The plurality of protrusions 28 allow the user to tactilely recognize the position of the tip E2T of the locking main body 20B, particularly the position facing the protrusion 14 in the pinched state. The plurality of protrusions 28 suppress slippage on the outer surface of the locking piece 20 such as a user's finger in the transition to the pinched state.

発音孔２３の内部には、爪受け部２４から外側（図２の下側）に向けて区画壁２９が立設されている。幅方向において、区画壁２９は、発音孔２３の全体にわたり位置する。区画壁２９は、１つの発音孔２３を、基端Ｅ２Ｂの側の空間Ｓ１と、先端Ｅ２Ｔの側の空間Ｓ２とに区画する。空間Ｓ１は、挟持状態において爪部１３を入れるための空間であり、挟持状態での爪部１３を長手方向で位置決めするための空間でもある。空間Ｓ２は、発音孔２３のなかの空間Ｓ１以外の空間であり、例えば、可聴域の音を発音孔２３で増幅させるため機能を備えてもよい。すなわち、長手方向における区画壁２９の位置は、可聴域の音を発音孔２３にて共鳴させる位置であることが好ましい。 Inside the sounding hole 23, a partition wall 29 is erected from the claw receiving portion 24 toward the outside (lower side of FIG. 2). In the width direction, the partition wall 29 is located over the entire sounding hole 23. The partition wall 29 partitions one sounding hole 23 into a space S1 on the side of the base end E2B and a space S2 on the side of the tip E2T. The space S1 is a space for inserting the claw portion 13 in the sandwiched state, and is also a space for positioning the claw portion 13 in the sandwiched state in the longitudinal direction. The space S2 is a space other than the space S1 in the sounding hole 23, and may have a function for amplifying the sound in the audible range in the sounding hole 23, for example. That is, the position of the partition wall 29 in the longitudinal direction is preferably a position where the sound in the audible range is resonated in the sounding hole 23.

図３が示すように、長手方向において、ヒンジ部３０と爪部１３との距離は、被係止距離Ｌ１１である。長手方向において、爪誘導部１２の内側端（図３の上端）とヒンジ部３０との距離は、誘導距離Ｌ１２である。長手方向において、爪受け部２４の縁２４Ｅとヒンジ部３０との距離は、係止距離Ｌ２１である。 As shown in FIG. 3, the distance between the hinge portion 30 and the claw portion 13 in the longitudinal direction is the locked distance L11. In the longitudinal direction, the distance between the inner end (upper end of FIG. 3) of the claw guiding portion 12 and the hinge portion 30 is the guiding distance L12. In the longitudinal direction, the distance between the edge 24E of the claw receiving portion 24 and the hinge portion 30 is the locking distance L21.

被係止距離Ｌ１１は、係止距離Ｌ２１よりも長く、それによって、挟持状態では、爪部１３が爪受け部２４に引っ掛かることが可能となる。誘導距離Ｌ１２は、被係止距離Ｌ１１よりも短く、かつ、係止距離Ｌ２１よりも長い。それによって、挟持状態への遷移では、爪誘導部１２の誘導斜面が、爪受け部２４の縁２４Ｅを押圧し、かつ、誘導斜面の傾斜に追従して爪誘導部１２が爪受け部２４の縁２４Ｅを滑るように、爪部１３が開口部内に近づくことが可能となる。 The locked distance L11 is longer than the locked distance L21, so that the claw portion 13 can be caught by the claw receiving portion 24 in the pinched state. The induction distance L12 is shorter than the locked distance L11 and longer than the locking distance L21. As a result, in the transition to the pinching state, the guiding slope of the claw guiding portion 12 presses the edge 24E of the claw receiving portion 24, and the claw guiding portion 12 follows the inclination of the guiding slope and causes the claw guiding portion 12 of the claw receiving portion 24. The claw portion 13 can approach the inside of the opening so as to slide on the edge 24E.

図４が示すように、ヒンジ部３０は、折り曲げ部３１と連結部３２とから構成される。折り曲げ部３１の厚みＷＴは、連結部３２の厚みよりも薄い。長手方向において、折り曲げ部３１の長さＷＨは、ヒンジ部３０の長さＷＬから長さＷＨを差し引いた長さ、すなわち、連結部３２の長さよりも短い。 As shown in FIG. 4, the hinge portion 30 is composed of a bent portion 31 and a connecting portion 32. The thickness WT of the bent portion 31 is thinner than the thickness of the connecting portion 32. In the longitudinal direction, the length WH of the bent portion 31 is shorter than the length obtained by subtracting the length WH from the length WL of the hinge portion 30, that is, the length of the connecting portion 32.

ヒンジ部３０は、ヒンジ部３０のなかで長手方向の長さが短い折り曲げ部３１を別途備えるため、挟持状態への遷移において、折れ曲がる部位が長手方向でばらつくことを抑える。折れ曲がる部位の長手方向のばらつきは、被係止距離Ｌ１１、誘導距離Ｌ１２、および、係止距離Ｌ２１のばらつきを招く。この点、ヒンジ部３０が別途折り曲げ部３１を備える構成であれば、これらの距離のばらつきを抑えること、ひいては、爪誘導部１２と爪受け部２４の縁２４Ｅとの相関による爪部１３の誘導の再現性を高めることが可能ともなる。また、ヒンジ部３０の曲げによる変性が、厚みの薄い折り曲げ部３１で生じるため、折り曲げ部３１の厚みが厚い構成と比べて、ヒンジ部３０における色味の変化を抑えることが可能ともなる。 Since the hinge portion 30 is separately provided with a bent portion 31 having a short length in the longitudinal direction in the hinge portion 30, it is possible to prevent the bent portion from being scattered in the longitudinal direction in the transition to the holding state. Variations in the longitudinal direction of the bent portion cause variations in the locked distance L11, the guided distance L12, and the locking distance L21. In this regard, if the hinge portion 30 is configured to separately include the bent portion 31, variation in these distances can be suppressed, and by extension, the claw portion 13 is guided by the correlation between the claw guiding portion 12 and the edge 24E of the claw receiving portion 24. It is also possible to improve the reproducibility of. Further, since the deformation of the hinge portion 30 due to bending occurs in the bent portion 31 having a thin thickness, it is possible to suppress the change in color in the hinge portion 30 as compared with the configuration in which the bent portion 31 has a large thickness.

［作用］
図５が示すように、樹脂製固定具が対象を固定する場合、まず、解除状態の樹脂製固定具において、基体片１０の突起１４が親指で押さえられ、係止片２０の突起２８が人差し指で押さえられ、それによって、ヒンジ部３０が解除状態から挟持状態に向けて遷移しはじめる。この間に、基体片１０と係止片２０との間には、対象が配置される。そして、基体片１０と係止片２０とによる対象の挟み込みが進むと、爪誘導部１２の誘導斜面が爪受け部２４の窪み２６に入り込み、爪誘導部１２の誘導斜面が爪受け部２４の縁２４Ｅを押圧しはじめる。 [Action]
As shown in FIG. 5, when the resin fixture fixes the object, first, in the released resin fixture, the protrusion 14 of the substrate piece 10 is pressed by the thumb, and the protrusion 28 of the locking piece 20 is the index finger. The hinge portion 30 begins to transition from the released state to the pinched state. During this time, an object is arranged between the substrate piece 10 and the locking piece 20. Then, as the object is sandwiched between the base piece 10 and the locking piece 20, the guide slope of the claw guide portion 12 enters the recess 26 of the claw receiving portion 24, and the guide slope of the claw guide portion 12 becomes the claw receiving portion 24. Start pressing edge 24E.

この際、爪受け部２４の縁２４Ｅにおいて、窪み２６は窪み２６への爪誘導部１２の進入を促し、かつ、爪誘導部１２の誘導斜面と爪受け部２４の縁２４Ｅとの相対的な位置のずれを抑える。また、爪誘導部１２の誘導斜面によって押圧される爪受け部２４は、図中上側に向けて反るように変形し、また、押圧の反力を受ける係止片２０は、反り部２１を起点として図中上側に向けて反るように変形する。そして、爪誘導部１２の誘導斜面が備える傾斜に従って、係止内面２０Ｓに向けた爪誘導部１２の接近が円滑に進む。 At this time, at the edge 24E of the nail receiving portion 24, the recess 26 promotes the entry of the nail guiding portion 12 into the recess 26, and the guide slope of the nail guiding portion 12 is relative to the edge 24E of the nail receiving portion 24. Suppresses misalignment. Further, the claw receiving portion 24 pressed by the guiding slope of the claw guiding portion 12 is deformed so as to warp toward the upper side in the drawing, and the locking piece 20 that receives the reaction force of the pressing deforms the warped portion 21. It is deformed so as to warp toward the upper side in the figure as a starting point. Then, the approach of the claw guiding portion 12 toward the locking inner surface 20S proceeds smoothly according to the inclination provided by the guiding slope of the claw guiding portion 12.

図６が示すように、爪受け部２４の縁２４Ｅと、係止内面２０Ｓの先端Ｅ２Ｔ側の縁とによって開口部が構成され、爪誘導部１２の誘導斜面がその開口部を通過すると、基体内面１０Ｓと係止内面２０Ｓとが対向する挟持状態に遷移する。そして、爪部１３は開口部内に進入して空間Ｓ１に収容され、爪部１３の爪端１３Ｅが、爪受け部２４の縁２４Ｅに引っ掛かる。 As shown in FIG. 6, an opening is formed by the edge 24E of the claw receiving portion 24 and the edge of the locking inner surface 20S on the tip E2T side, and when the guiding slope of the claw guiding portion 12 passes through the opening, the substrate is formed. The transition to a holding state in which the inner surface 10S and the locking inner surface 20S face each other. Then, the claw portion 13 enters the opening and is accommodated in the space S1, and the claw end 13E of the claw portion 13 is caught by the edge 24E of the claw receiving portion 24.

この際、反るように曲がっていた係止片２０や、誘導斜面に押圧されていた爪受け部２４の縁２４Ｅが、元の形状に戻り、形状が戻る際の振動によって発音孔２３で音が発生する。この間、複数の突起１４，２８は、挟持状態への遷移において、基体片１０の外面や係止片２０の外面で利用者の指が滑ることを抑える。 At this time, the locking piece 20 bent so as to warp and the edge 24E of the claw receiving portion 24 pressed against the induction slope return to the original shape, and the vibration when the shape returns makes a sound in the sound hole 23. Occurs. During this time, the plurality of protrusions 14 and 28 prevent the user's finger from slipping on the outer surface of the substrate piece 10 or the outer surface of the locking piece 20 in the transition to the sandwiched state.

なお、挟持状態から解除状態への遷移に際しては、まず、挟持状態の樹脂製固定具において、係止片２０の突起２８が人差し指で押さえられ、係止片２０の突起２５が親指で押さえられる。そして、爪受け部２４を係止本体部２０Ｂに向けて反らせる外力が爪受け部２４に作用し、それによって、爪部１３の爪端１３Ｅによる引っ掛かりが解除され、樹脂製固定具が解除状態に遷移する。 In the transition from the pinched state to the released state, first, in the resin fixture in the pinched state, the protrusion 28 of the locking piece 20 is pressed by the index finger, and the protrusion 25 of the locking piece 20 is pressed by the thumb. Then, an external force that bends the claw receiving portion 24 toward the locking main body portion 20B acts on the claw receiving portion 24, whereby the claw end 13E is released from being caught by the claw end 13E, and the resin fixture is released. Transition.

以上、上記実施形態によれば、以下の効果が得られる。
（１）解除状態から挟持状態への遷移に際し、爪部１３が開口部内に入るように、爪部１３と開口部とを爪誘導部１２が誘導する。そのため、基体片１０に係止片２０を係止させる操作を、片手によるヒンジ部３０の折り畳みによって利用者は実現できる。 As described above, according to the above embodiment, the following effects can be obtained.
(1) At the transition from the released state to the pinched state, the claw guiding portion 12 guides the claw portion 13 and the opening so that the claw portion 13 enters the opening. Therefore, the operation of locking the locking piece 20 to the substrate piece 10 can be realized by the user by folding the hinge portion 30 with one hand.

（２）挟持状態への遷移の完了時に音が発生するため、挟持状態への遷移の完了を利用者は音によって認識できる。それゆえに、暗所での利用のシーンや、片手での利用のシーンに適した操作性を樹脂製固定具に付与することが可能となる。 (2) Since a sound is generated when the transition to the pinch state is completed, the user can recognize the completion of the transition to the pinch state by the sound. Therefore, it is possible to provide the resin fixture with operability suitable for a scene of use in a dark place or a scene of use with one hand.

（３）係止本体部２０Ｂの発音孔２３を半ドーム状の爪受け部２４が覆うため、挟持状態への遷移の完了時に発生する音が共鳴によって増幅される。結果として、暗所での利用のシーンにさらに適した操作性を樹脂製固定具に付与することが可能となる。 (3) Since the sounding hole 23 of the locking main body 20B is covered with the semi-dome-shaped claw receiving portion 24, the sound generated at the completion of the transition to the pinching state is amplified by resonance. As a result, it becomes possible to impart operability to the resin fixture more suitable for the scene of use in a dark place.

（４）誘導斜面の押圧による反力が係止片２０に作用する際に、反り部２１を起点として係止片２０が反りやすくなる。結果として、係止片２０の反りの戻りに起因した音をより確実に発生させることが可能ともなる。 (4) When the reaction force due to the pressing of the induction slope acts on the locking piece 20, the locking piece 20 tends to warp starting from the warped portion 21. As a result, it is possible to more reliably generate the sound caused by the return of the warp of the locking piece 20.

（５）爪受け部２４の縁２４Ｅを誘導斜面が押圧するときに、爪受け部２４の縁２４Ｅと、誘導斜面との相対的な位置のずれを、誘導斜面を受け入れる窪み２６が抑える。そのため、誘導斜面の押圧による開口部の変形、ひいては、解除状態から挟持状態への遷移が円滑に行われる。 (5) When the guide slope presses the edge 24E of the claw receiving portion 24, the recess 26 that receives the guide slope suppresses the relative positional deviation between the edge 24E of the claw receiving portion 24 and the guide slope. Therefore, the deformation of the opening due to the pressing of the induction slope, and the transition from the released state to the pinched state are smoothly performed.

（６）基体片１０の内面と外面との差異、および、係止片２０の内面と外面との差異、さらには、基体片１０の先端Ｅ１Ｔや係止片２０の先端Ｅ２Ｔの位置を、突起１４，２５，２８に触れる利用者は、触覚で認識することが可能ともなる。そのため、視界が良好ではないシーンでの対象の固定操作や固定の解除操作が円滑に行われる。 (6) The difference between the inner surface and the outer surface of the base piece 10, the difference between the inner surface and the outer surface of the locking piece 20, and the positions of the tip E1T of the base piece 10 and the tip E2T of the locking piece 20 are projected. Users who touch 14, 25, and 28 can also recognize by touch. Therefore, the fixing operation and the fixing release operation of the target are smoothly performed in the scene where the visibility is not good.

なお、上記実施形態は以下のように変更して実施することも可能である。
［樹脂製固定具］
・樹脂製固定具を構成する樹脂は、例えば、ポリプロピレン、ポリフッ化ビニリデン、エラストマー、ポリプロピレンとポリエチレンとの混合物、ポリプロピレンとエラストマーとの混合物である。ポリプロピレンとポリエチレンとの混合物は、例えば、混合物の重量に対するポリプロピレンの重量の比が５０％以上であることが好ましい。 The above embodiment can be modified and implemented as follows.
[Resin fixture]
-The resin constituting the resin fixture is, for example, polypropylene, polyvinylidene fluoride, an elastomer, a mixture of polypropylene and polyethylene, or a mixture of polypropylene and an elastomer. The mixture of polypropylene and polyethylene preferably has, for example, a ratio of the weight of polypropylene to the weight of the mixture of 50% or more.

ポリエチレンの曲げ強さが７０ｋｇｆ／ｃｍ^２であることに対して、ポリプロピレンの曲げ強さは４２０〜５６０ｋｇｆ／ｃｍ^２である。上述したように、係止片２０の反りや爪受け部２４の変形が伴う樹脂製固定具では、ポリプロピレンの重量比が５０％以上であることによって、樹脂製固定具の機械的な強度を得ることが可能ともなる。また、樹脂製固定具によって固定される対象の厚みが大きいほど、挟持状態での基体片１０や係止片２０は湾曲する。そのため、ポリプロピレンの重量比が５０％以上である構成であれば、挟持状態への遷移に伴う係止片２０の反りの他に、挟持状態での基体片１０や係止片２０の変形に対しても、機械的な強度を得ることが可能ともなる。他方、挟持状態に遷移した際に生じる音を大きくする観点では、樹脂製固定具を構成する樹脂の曲げ強度が高すぎないことが好ましい。この点、樹脂製固定具を構成する樹脂が、ポリプロピレンとポリエチレンとの混合物であって、かつ、混合物の重量に対するポリエチレンの重量の比が１０％以上２０％以下であれば、樹脂製固定具の機械的な強度を得ることに加えて、挟持状態に遷移した際に生じる音を大きくすることが可能ともなる。 The flexural strength of polyethylene is 70 kgf / cm ² , whereas the flexural strength of polypropylene is 420 to 560 kgf / cm ² . As described above, in the resin fixture in which the locking piece 20 is warped and the claw receiving portion 24 is deformed, the mechanical strength of the resin fixture is obtained by the weight ratio of polypropylene being 50% or more. It also becomes possible. Further, the thicker the object to be fixed by the resin fixture, the more the substrate piece 10 and the locking piece 20 in the sandwiched state are curved. Therefore, if the weight ratio of polypropylene is 50% or more, in addition to the warp of the locking piece 20 due to the transition to the holding state, the deformation of the substrate piece 10 and the locking piece 20 in the holding state However, it is also possible to obtain mechanical strength. On the other hand, from the viewpoint of increasing the sound generated when the transition to the holding state is made, it is preferable that the bending strength of the resin constituting the resin fixture is not too high. In this regard, if the resin constituting the resin fixture is a mixture of polypropylene and polyethylene and the ratio of the weight of polyethylene to the weight of the mixture is 10% or more and 20% or less, the resin fixture of the resin fixture In addition to obtaining mechanical strength, it is also possible to increase the sound generated when transitioning to the pinching state.

［係止歯１１］
・係止歯１１の先端面は、基体片１０の長手方向に延びる波形状に限らず、例えば、基体片１０の長手方向に延びる直線状や半円弧状とすることも可能である。係止歯１１の先端面が有する形状は、樹脂製固定具の固定対象の材質や形状に応じて適宜変更することが可能である。 [Locking tooth 11]
The tip surface of the locking tooth 11 is not limited to a wavy shape extending in the longitudinal direction of the substrate piece 10, and may be, for example, a linear shape or a semicircular arc shape extending in the longitudinal direction of the substrate piece 10. The shape of the tip surface of the locking tooth 11 can be appropriately changed according to the material and shape of the fixing target of the resin fixture.

［爪誘導部１２］
・爪誘導部１２は、係止歯１１と別体とすることも可能である。この際、爪誘導部１２は、基体片１０の長手方向に延びる複数の突片に具体化することも可能である。要は、爪誘導部１２は、爪部１３から基端Ｅ１Ｂに向けて内側に徐々に変位する傾斜を有した誘導斜面を備える構成であればよい。そして、爪誘導部１２は、解除状態から挟持状態への遷移の際に、爪受け部２４の縁２４Ｅと誘導斜面とが対向し、爪受け部２４の縁２４Ｅに対する誘導斜面の押圧によって爪部１３が開口部内に誘導される構造体であればよい。 [Claw guide 12]
-The claw guide portion 12 can be separated from the locking tooth 11. At this time, the claw guiding portion 12 can be embodied into a plurality of protrusions extending in the longitudinal direction of the substrate piece 10. In short, the claw guide portion 12 may be configured to include a guide slope having an inclination that gradually displaces inward from the claw portion 13 toward the base end E1B. Then, in the transition from the released state to the pinched state, the claw guiding portion 12 faces the edge 24E of the claw receiving portion 24 and the guiding slope, and the claw portion is pressed by pressing the guiding slope against the edge 24E of the claw receiving portion 24. It may be a structure in which 13 is guided into the opening.

［爪部１３］
・爪部１３は、基体片１０の先端Ｅ１Ｔから下方に湾曲するフック状に限らず、例えば、単に長手方向に突き出る片とすることも可能である。また、基体片１０の先端Ｅ１Ｔは、幅方向に並ぶ複数の爪部１３を備えることも可能である。この際、基体片１０は、各爪部１３に１つずつ爪誘導部１２を備えることも可能であり、また、全ての爪部１３に共通する幅方向に連続した１つの爪誘導部１２を備えることも可能である。 [Claw part 13]
The claw portion 13 is not limited to a hook shape that curves downward from the tip E1T of the substrate piece 10, and can be, for example, a piece that simply protrudes in the longitudinal direction. Further, the tip E1T of the substrate piece 10 can be provided with a plurality of claw portions 13 arranged in the width direction. At this time, the substrate piece 10 can be provided with one claw guiding portion 12 for each claw portion 13, and one claw guiding portion 12 continuous in the width direction common to all the claw portions 13 is provided. It is also possible to prepare.

［反り部２１］
・係止片２０は、貫通孔２２を割愛された構成とすることも可能である。このような構成であっても、反り部２１の厚みは、幅方向の全体にわたり基端Ｅ２Ｂや先端Ｅ２Ｔよりも薄い、あるいは、反り部２１の幅方向の長さは、基端Ｅ２Ｂや先端Ｅ２Ｔよりも短いため、反り部２１を起点として係止片２０を反りやすくすることは可能である。 [Curved part 21]
The locking piece 20 may have a configuration in which the through hole 22 is omitted. Even with such a configuration, the thickness of the warped portion 21 is thinner than the base end E2B and the tip E2T over the entire width direction, or the length of the warped portion 21 in the width direction is the base end E2B and the tip E2T. Since it is shorter than that, it is possible to make the locking piece 20 easy to warp starting from the warped portion 21.

なお、係止片２０は、反り部２１を割愛し、貫通孔２２のみを備える構成とすることも可能であり、また、反り部２１に相当する部位での厚みを基端Ｅ２Ｂや先端Ｅ２Ｔの厚みよりも薄くすることも可能である。 The locking piece 20 may have a configuration in which the warped portion 21 is omitted and only the through hole 22 is provided, and the thickness at the portion corresponding to the warped portion 21 is the thickness of the base end E2B and the tip end E2T. It is also possible to make it thinner than the thickness.

［発音孔２３］
・係止片２０は、複数の発音孔２３を備えることも可能である。この際、発音孔２３の大きさ、形状、数量に合わせて、発音孔２３で音が発生するように、さらには、発音孔２３で音が共鳴するように、区画壁２９は配置される。なお、発音孔２３を割愛することも可能である。 [Sound hole 23]
The locking piece 20 can also be provided with a plurality of sounding holes 23. At this time, the partition wall 29 is arranged so that the sound is generated in the sounding hole 23 and the sound resonates in the sounding hole 23 according to the size, shape, and quantity of the sounding hole 23. It is also possible to omit the sounding hole 23.

［爪受け部２４］
・爪受け部２４の縁２４Ｅは、外面において、先端Ｅ２Ｔに向けて窪む階段構造を備えることも可能である。例えば、爪受け部２４の縁２４Ｅは、挟持状態への遷移において、爪部１３の爪端が嵌る第１段差部と、挟持状態において爪部１３の爪端が嵌る第２段差部とを備え、第２段差部が第１段差部の外側かつ先端Ｅ２Ｔ側に位置することも可能である。こうした階段構造を縁２４Ｅが備える構成であれば、爪部１３の爪端が第１段差部に嵌ることによって、基体片１０に対して係止片２０を仮止めすることが可能となり、爪部１３の爪端が第２段差部に嵌ることによって、基体片１０に対して係止片２０を位置決めすることが可能となる。そのため、樹脂製固定具の操作性をさらに拡張することが可能ともなる。 [Claw receiving part 24]
The edge 24E of the claw receiving portion 24 may be provided with a staircase structure that is recessed toward the tip E2T on the outer surface. For example, the edge 24E of the claw receiving portion 24 includes a first step portion to which the claw end of the claw portion 13 fits in the transition to the pinching state, and a second step portion to which the claw end of the claw portion 13 fits in the pinching state. It is also possible that the second step portion is located outside the first step portion and on the tip E2T side. If the edge 24E is provided with such a staircase structure, the locking piece 20 can be temporarily fixed to the substrate piece 10 by fitting the claw end of the claw portion 13 into the first step portion, and the claw portion can be temporarily fixed. By fitting the claw end of 13 into the second step portion, the locking piece 20 can be positioned with respect to the base piece 10. Therefore, the operability of the resin fixture can be further expanded.

［ヒンジ部３０］
・図７が示すように、ヒンジ部３０は、長手方向の中心から各片に向けて順に、折り曲げ部３１、連結部３２、補強部３４を備えることも可能である。補強部３４の厚みは、連結部３２よりも厚く、かつ、基体片１０や係止片２０の厚みよりも薄い。こうした構成であれば、上述した折り曲げ部３１によって得られる効果の他に、ヒンジ部３０と各片との連結における機械的な強度を得ることが可能ともなる。この際、補強部３４は、各片から連結部３２に向けて、幅方向の長さを徐々に短くすることも可能である。また、図８が示すように、補強部３４、連結部３２、折り曲げ部３１において、幅方向の長さを各片よりも短い一定値とすることも可能である。 [Hinge part 30]
As shown in FIG. 7, the hinge portion 30 may be provided with a bent portion 31, a connecting portion 32, and a reinforcing portion 34 in this order from the center in the longitudinal direction toward each piece. The thickness of the reinforcing portion 34 is thicker than that of the connecting portion 32 and thinner than the thickness of the base piece 10 and the locking piece 20. With such a configuration, in addition to the effect obtained by the bent portion 31 described above, it is also possible to obtain mechanical strength in connecting the hinge portion 30 and each piece. At this time, the length of the reinforcing portion 34 in the width direction can be gradually shortened from each piece toward the connecting portion 32. Further, as shown in FIG. 8, in the reinforcing portion 34, the connecting portion 32, and the bent portion 31, the length in the width direction can be set to a constant value shorter than that of each piece.

［段差部］
・基体片１０の先端Ｅ１Ｔや係止片２０の先端Ｅ２Ｔなどを触覚によって認識させる機能は、複数の突起１４，２５，２８の他に、例えば、複数の溝や粗面などに具体化することも可能である。 [Step]
