Description
本発明は、複数本のワイヤを内側に空間部を有し且つ各ワイヤ間に軸線方向に間隙部を開けて螺旋巻きした螺旋体を径方向に複数階層させた線状部材に関する。 The present invention relates to a linear member in which a plurality of wires have a space inside, and a spiral body spirally wound with a gap portion between each wire in the axial direction is formed in a plurality of layers in the radial direction.
従来この種の線状部材としては、本願発明者による、超弾性形状記憶合金よりなる複数本のワイヤを配列した基本体をワイヤの配列方向に螺旋巻きにし、内側に空間部を形成し、線状部材の外径をＤ、螺旋巻きのピッチをＰとして、−０．１９１Ｄ２＋１．０３Ｄ−０．４２７≦Ｐ≦３．４４Ｄ２−５．０６Ｄ＋２．３２の範囲内とした線状部材が知られている（下記特許文献１参照）。Conventionally, as this kind of linear member, a basic body according to the inventor of the present application in which a plurality of wires made of superelastic shape memory alloy are arranged is spirally wound in the wire arrangement direction, and a space portion is formed inside, A linear member having an outer diameter of D-shaped member and a spiral winding pitch of P-0.191D 2 + 1.03D−0.427 ≦ P ≦ 3.44D 2 −5.06D + 2.32 Known (see Patent Document 1 below).
かかる線状部材によれば、装身具として、輪ゴムのように伸ばして手首に嵌めるような場合に、数十パーセントの伸び率を実現しつつ、かつ、復元力に優れた線状部材を実現することができる。 According to such a linear member, when it is stretched like a rubber band and fits on the wrist as an accessory, it realizes a linear member that achieves an elongation of several tens of percent and has excellent restoring force. Can do.
ここで、近年、装身具および医療用として望まれる線状部材は、伸び率と復元力とを備えるのみならず、しなやかさを兼ね備えることが望まれている。 Here, in recent years, linear members desired for jewelry and medical use are desired not only to have an elongation rate and a restoring force, but also to have flexibility.
そこで、本発明は、しなやかさを兼ね備えた線状部材を提供することを目的とする。 Then, an object of this invention is to provide the linear member which has suppleness.
第１発明の線状部材は、複数本のワイヤを内側に空間部を有し且つ各ワイヤ間に軸線方向に間隙部を開けて螺旋巻きした螺旋体を径方向に複数階層させた線状部材であって、
試験力に対する変位に関する引張試験において、該線状部材が破断する最大試験力の半分の半試験力における変位が、該最大試験力における変位の２５％〜３５％となるように、前記階層数と各階層における各ワイヤのピッチと各階層における各ワイヤの螺旋巻角度とを決定することを特徴とする。The linear member according to the first aspect of the present invention is a linear member in which a plurality of wires have a space inside, and a spiral body spirally wound by opening a gap in the axial direction between the wires is formed in a plurality of layers in the radial direction. There,
In the tensile test related to the displacement with respect to the test force, the number of layers is set so that the displacement at the half test force that is half the maximum test force at which the linear member breaks is 25% to 35% of the displacement at the maximum test force. The pitch of each wire in each layer and the spiral winding angle of each wire in each layer are determined.
本願発明者の鋭意の試験研究によれば、線状部材のしなやかさは、加重の比較的小さな領域では伸び率が際立つ一方、加重が大きくなっていった場合に適度な硬さが維持されるとの知見に至った。 According to the inventor's diligent test research, the flexibility of the linear member is conspicuous in the region where the load is relatively small, while the elongation rate is conspicuous, while the moderate hardness is maintained when the load increases. And led to the knowledge.
第１発明は、かかる知見に基づいて、試験力に対する変位に関する引張試験において、線状部材が破断する最大試験力の半分の半試験力における変位が、該最大試験力における変位の２５％〜３５％となるように、階層数と各階層における各ワイヤのピッチと各階層における各ワイヤの螺旋巻角度とを決定する。 Based on this knowledge, the first invention is a tensile test related to the displacement against the test force. The displacement at the half test force that is half the maximum test force at which the linear member breaks is 25% to 35% of the displacement at the maximum test force. The number of layers, the pitch of each wire in each layer, and the spiral winding angle of each wire in each layer are determined so as to be%.
ここで、線状部材は、通常、破断直前で変位量が大きくなるところ、線状部材が破断する最大試験力の半分の半試験力を基準とすることで、加重の小さな領域での伸び率を特定することができる。 Here, the linear member usually has a large amount of displacement immediately before breakage, but the elongation rate in a region with a small load is obtained by using a half test force that is half of the maximum test force at which the linear member breaks. Can be specified.
さらに、半試験力における変位が、破断時の最大試験力における変位の２５％未満の場合には、加重の小さな領域での伸び率が小さくしなやかに欠けてしまう。 Further, when the displacement at the half test force is less than 25% of the displacement at the maximum test force at the time of breaking, the elongation rate in the region with a small load is small and lacks easily.
一方で、半試験力における変位が、破断時の最大試験力における変位の３５％を超える場合には、加重が大きくなっていった際に伸び切ってしまい、逆にしなやかさに欠けてしまう。 On the other hand, when the displacement at the half test force exceeds 35% of the displacement at the maximum test force at the time of rupture, the load increases as the load increases, and conversely lacks flexibility.
そこで、第１発明は、線状部材が破断する最大試験力の半分の半試験力における変位が、該最大試験力における変位の２５％〜３５％となるように、階層数と各階層における各ワイヤのピッチと各階層における各ワイヤの螺旋巻角度とを決定することで、しなやかさを兼ね備えることができる。 Accordingly, the first invention provides the number of layers and each level in each layer so that the displacement at the half test force that is half the maximum test force at which the linear member breaks is 25% to 35% of the displacement at the maximum test force. By determining the pitch of the wire and the spiral winding angle of each wire in each layer, it is possible to combine flexibility.
第２発明の線状部材は、第１発明の線状部材において、
複数階層の前記螺旋体は、隣接する階層の該螺旋体の螺旋方向が逆方向となるように配置されることを特徴とする。The linear member of the second invention is the linear member of the first invention,
The spirals in a plurality of layers are arranged such that the spiral directions of the spirals in adjacent layers are opposite to each other.
第２発明の線状部材によれば、隣接する階層の螺旋体の螺旋方向が逆方向となるように配置することで、高い復元力を実現することができると共に、加重が大きくなっていった際に伸び切ってしまい、逆にしなやかさに欠けてしまうことを防止することができる。 According to the linear member of the second invention, by arranging the spirals of the spirals of the adjacent layers to be opposite directions, a high restoring force can be realized and the weight increases. In other words, it is possible to prevent the suppleness from being lost.

ここで、階層数と各階層における各ワイヤ１のピッチと各階層における各ワイヤ１の螺旋巻角度θとは、当該線状部材の試験力に対する変位に関する引張試験において、当該線状部材が破断する最大試験力Ｆの半分の半試験力ｆにおける変位ｄが、該最大試験力における変位Ｄの２５％〜３５％となるように決定される。 Here, the number of layers, the pitch of each wire 1 in each layer, and the spiral winding angle θ of each wire 1 in each layer are determined in the tensile test related to the displacement of the linear member against the test force. The displacement d at the half test force f that is half the maximum test force F is determined to be 25% to 35% of the displacement D at the maximum test force.
なお、ワイヤ１のピッチとは、１回転当たりの送り量であり、ワイヤ１の螺旋巻角度θは、図１に示すように、当該線状部材の長手方向とワイヤの巻き方向とのなす角である。 Note that the pitch of the wire 1 is a feed amount per one rotation, and the spiral winding angle θ of the wire 1 is an angle formed by the longitudinal direction of the linear member and the winding direction of the wire as shown in FIG. It is.

次に、図３において、図２に示した実際の４層の線状部材の破断試験の結果について説明する。 Next, in FIG. 3, the result of the fracture test of the actual four-layer linear member shown in FIG. 2 will be described.
図３（Ａ）は、かかる４層の線状部材の破断試験の結果であり、図３（Ｂ）は、同結果に当該線状部材が破断する最大試験力Ｆの半分の半試験力ｆにおける変位ｄを示した図である。 FIG. 3 (A) shows the result of a fracture test of such a four-layer linear member, and FIG. 3 (B) shows a half test force f that is half the maximum test force F at which the linear member breaks. It is the figure which showed the displacement d in.
図３（Ａ）において、破断試験は、同一試験片に対して３回行い、１回目の最大試験力Ｆ１は２．２４［ｋＮ］であり、その最大変位Ｄ１は、２１．８［ｍｍ］である。２回目の最大試験力Ｆ２は２．２２［ｋＮ］であり、その最大変位Ｄ２は、２１．９［ｍｍ］である。３回目の最大試験力Ｆ３は２．２０［ｋＮ］であり、その最大変位Ｄ３は、１９．９［ｍｍ］である。 In FIG. 3A, the fracture test is performed three times on the same test piece, the first maximum test force F1 is 2.24 [kN], and the maximum displacement D1 is 21.8 [mm]. It is. The second maximum test force F2 is 2.22 [kN], and the maximum displacement D2 is 21.9 [mm]. The third maximum test force F3 is 2.20 [kN], and the maximum displacement D3 is 19.9 [mm].
図３（Ｂ）において、１回目の半試験力ｆ１は１．１２［ｋＮ］であり、その変位ｄ１は、５．５［ｍｍ］である。２回目の半試験力ｆ２は１．１１［ｋＮ］であり、その変位ｄ２は、５．８［ｍｍ］である。３回目の最半試験力ｆ３は１．１０［ｋＮ］であり、その変位ｄ３は、５．６［ｍｍ］である。 In FIG. 3B, the first half test force f1 is 1.12 [kN], and the displacement d1 is 5.5 [mm]. The second half test force f2 is 1.11 [kN], and the displacement d2 is 5.8 [mm]. The third half test force f3 is 1.10 [kN], and the displacement d3 is 5.6 [mm].
ここから、１回目における最大変位Ｄ１に対する半試験力ｆ１の変位ｄ１は、２５．２％であり、２回目における最大変位Ｄ２に対する半試験力ｆ２の変位ｄ２は、２６．５％であり、３回目における最大変位Ｄ３に対する半試験力ｆ３の変位ｄ３は、２８．１％である。 From this, the displacement d1 of the half test force f1 with respect to the maximum displacement D1 at the first time is 25.2%, and the displacement d2 of the half test force f2 with respect to the maximum displacement D2 at the second time is 26.5%. The displacement d3 of the half test force f3 with respect to the maximum displacement D3 at the second time is 28.1%.
このように、線状部材が破断する最大試験力Ｆの半分の半試験力ｆにおける変位ｄが、該最大試験力における変位Ｄの２５％〜３５％となるように、階層数と各階層における各ワイヤ１のピッチと各階層における各ワイヤ１の螺旋巻角度θとを決定することで、しなやかさを兼ね備えることができる。 As described above, the number of layers and the number of layers in each layer are set so that the displacement d at the half test force f that is half of the maximum test force F at which the linear member breaks is 25% to 35% of the displacement D at the maximum test force. By determining the pitch of each wire 1 and the spiral winding angle θ of each wire 1 in each layer, flexibility can be achieved.
すなわち、線状部材が破断する最大試験力Ｆの半分の半試験力ｆを基準とすることで、加重の小さな領域での伸び率を特定することができ、かかる荷重の小さな領域での半試験力ｆにおける変位ｄが、破断時の最大試験力Ｆにおける変位Ｄの２５％未満の場合のように、加重の小さな領域での伸び率が小さくしなやかに欠けてしまうこともない。 That is, by using the half test force f that is half of the maximum test force F at which the linear member breaks as a reference, it is possible to specify the elongation rate in a region with a small load, and the half test in a region with a small load. As in the case where the displacement d in the force f is less than 25% of the displacement D in the maximum test force F at the time of breakage, the elongation rate in the region with a small load is not easily lost.
一方で、半試験力ｆにおける変位ｄが、破断時の最大試験力Ｆにおける変位の３５％を超える場合のように、加重が大きくなっていった際に伸び切ってしまい、逆にしなやかさに欠けてしまうということもない。 On the other hand, as the displacement d at the half test force f exceeds 35% of the displacement at the maximum test force F at the time of breakage, it is fully extended when the load increases, and on the contrary, it is supple. There is no lack of it.
なお、本実施形態では、４層の線状部材について説明したが、これに限定されるものではなく、図４（Ａ）に正面図、図４（Ｂ）に断面図で示す実際の２層の線状部材や３層、５層、６層・・の線状部材（図示省略）において、線状部材が破断する最大試験力Ｆの半分の半試験力ｆにおける変位ｄが、該最大試験力における変位Ｄの２５％〜３５％となるように、階層数と各階層における各ワイヤ１のピッチと各階層における各ワイヤ１の螺旋巻角度θとを決定してもよい。 In the present embodiment, the four-layer linear member has been described. However, the present invention is not limited to this, and the actual two-layer shown in FIG. 4A is a front view and FIG. 4B is a cross-sectional view. In a linear member or a three-layer, five-layer, six-layer linear member (not shown), the displacement d at a half test force f that is half the maximum test force F at which the linear member breaks is the maximum test. The number of layers, the pitch of each wire 1 in each layer, and the spiral winding angle θ of each wire 1 in each layer may be determined so as to be 25% to 35% of the displacement D in force.
さらに、線状部材の階層数と各階層における各ワイヤ１のピッチと各階層における各ワイヤ１の螺旋巻角度θとを決定する際には、当該線状部材が破断する最大試験力Ｆの半分の半試験力ｆにおける変位ｄが、該最大試験力Ｆにおける変位Ｄの２５％〜３０％となることがより好ましい。これにより、荷重が大きくなった際の線状部材の伸び切りを抑えて、適度な弾力性のあるしなやかさを実現することができる。 Furthermore, when determining the number of layers of the linear member, the pitch of each wire 1 in each layer, and the spiral winding angle θ of each wire 1 in each layer, half of the maximum test force F at which the linear member breaks. The displacement d at the half test force f is more preferably 25% to 30% of the displacement D at the maximum test force F. As a result, it is possible to suppress the expansion of the linear member when the load increases, and to realize flexibility with moderate elasticity.
以上説明した本実施形態の線状部材に対して、図５（Ａ）に正面図、図５（Ｂ）に断面図で示す比較例の線状部材では、図６（Ａ）に、かかる比較例の線状部材の破断試験の結果、図６（Ｂ）に、同結果に当該線状部材が破断する最大試験力Ｆの半分の半試験力ｆにおける変位ｄを示した図で示すように、線状部材が破断する最大試験力Ｆの半分の半試験力ｆにおける変位ｄが、最大試験力Ｆにおける変位Ｄの２５％未満となってしまい、加重の小さな領域での伸び率が小さくしなやかに欠けてしまう。 Compared to the linear member of the present embodiment described above, the comparative linear member shown in the front view in FIG. 5A and the cross-sectional view in FIG. As a result of the break test of the example linear member, as shown in FIG. 6B, the displacement d at the half test force f that is half the maximum test force F at which the linear member breaks is shown in FIG. The displacement d at the half test force f, which is half the maximum test force F at which the linear member breaks, is less than 25% of the displacement D at the maximum test force F, and the elongation in a small load region is small. Will be lacking.
また、図７（Ａ）に正面図、図７（Ｂ）に断面図で示す他の比較例の線状部材では、図８（Ａ）に、かかる比較例の線状部材の破断試験の結果、図８（Ｂ）に、同結果に当該線状部材が破断する最大試験力Ｆの半分の半試験力ｆにおける変位ｄを示した図で示すように、線状部材が破断する最大試験力Ｆの半分の半試験力ｆにおける変位ｄが、最大試験力Ｆにおける変位Ｄの２５％未満となってしまい、加重の小さな領域での伸び率が小さくしなやかに欠けてしまう。 Moreover, in the linear member of the other comparative example shown in a front view in FIG. 7A and a cross-sectional view in FIG. 7B, the result of the fracture test of the linear member in the comparative example is shown in FIG. FIG. 8B shows the maximum test force at which the linear member breaks, as shown in FIG. 8B, which shows the displacement d at half test force f that is half of the maximum test force F at which the linear member breaks. The displacement d at half the test force f, which is half of F, is less than 25% of the displacement D at the maximum test force F, and the elongation in a region with a small load is small and lacks flexibly.
次に、参考として、しなやかさを表す別の指標として、図９（Ａ）に、ハング量（Ｈ）とたわみ量（δ）との関係をプロットして示す。ここでのハング量（Ｈ）とたわみ量（δ）は、図９（Ｂ）に模式的に示すように、線状部材の一端から２５０ｍｍをハング端とし、他端を固定し、ハング端を自重でたわませたときのハング量（Ｈ）とたわみ量（δ）となっている。 Next, for reference, FIG. 9A is a plot of the relationship between the hang amount (H) and the deflection amount (δ) as another index representing flexibility. As shown schematically in FIG. 9B, the hang amount (H) and the deflection amount (δ) are 250 mm from one end of the linear member, the other end is fixed, and the hang end is fixed. The amount of hang (H) and the amount of deflection (δ) when deflected by its own weight are shown.
しなやかな部材ほど、自重で下方にたわむことから、たわみ量δは大きな値となり、ハング量Ｈは小さな値となる。 The more flexible the member is bent downward due to its own weight, the deflection amount δ is a large value and the hang amount H is a small value.
図９（Ａ）に示すように、他の比較例の線状部材（図７，図８の線状部材）と比較して、実施例の線状部材（図２，図３の線状部材）のしなやかさが高い。 As shown in FIG. 9A, the linear member of the example (the linear member of FIGS. 2 and 3) is compared with the linear member of the other comparative example (the linear member of FIGS. 7 and 8). ) High flexibility.
以上詳しく説明したように、本実施形態の線状部材によれば、しなやかさを兼ね備えた線状部材を提供することができる。 As described above in detail, according to the linear member of the present embodiment, it is possible to provide a linear member having flexibility.
