Description

本発明は、釣竿の性能を客観的に評価するための評価方法に関する。 The present invention relates to an evaluation method for objectively evaluating the performance of a fishing rod.

釣竿には、様々な特性が要求される。釣竿の設計時に重要視される特性には、客観的に測定可能な客観的特性があり、例えば、竿体の曲げ剛性やねじれ剛性が挙げられる。 Fishing rods are required to have various characteristics. Characteristics that are emphasized when designing a fishing rod include objective characteristics that can be objectively measured, and examples thereof include flexural rigidity and torsional rigidity of the rod body.

釣竿のこのような客観的特性は、定量的なものではあるものの、釣竿の実際の動きが反映されたものではない、すなわち動的な評価ではないことから、このような特性をもって、釣竿の性能を客観的を評価することは事実上困難であるという問題がある。 Although such objective characteristics of the fishing rod are quantitative, they do not reflect the actual movement of the fishing rod, that is, they are not a dynamic evaluation. Therefore, the performance of the fishing rod has such characteristics. There is a problem that it is practically difficult to evaluate objectively.

従来より、釣竿の性能を客観的に評価することが求められている。例えば、特開２０１３−１５３７４０号公報（特許文献１）には、物理的要素による数値化された感性的評価を用いて、樹脂製の管状若しくは板状の長尺部材を設計する設計システムが開示されている。 Conventionally, it has been required to objectively evaluate the performance of a fishing rod. For example, Japanese Patent Application Laid-Open No. 2013-153740 (Patent Document 1) discloses a design system for designing a tubular or plate-shaped long member made of resin by using a quantified emotional evaluation by physical elements. Has been done.

しかしながら、特許文献１に係る方法では、釣竿の現実の使用状態や動きなどの動的な変化を必ずしも正確に反映できていないため、釣竿の性能を客観的に評価できているとは言い難い。 However, it cannot be said that the performance of the fishing rod can be objectively evaluated because the method according to Patent Document 1 cannot always accurately reflect dynamic changes such as the actual usage state and movement of the fishing rod.

特開２０１３−１５３７４０号公報Japanese Unexamined Patent Publication No. 2013-153740

The same reference numerals are given to the components common to each drawing. It should be noted that each drawing is not always drawn to the correct scale for convenience of explanation.

図１は、本発明の評価方法に使用するひずみエネルギーの計測システム１の全体の構成を模式的に示す図である。図１に示されるように、計測システム１は、竿の各位置に所定のマーキング８を施した釣竿１０と、該釣竿１０の一端に取り付けられた錘２０と、当該マーキング８を捉えるカメラ３０とで構成される。操作者が、釣竿１０を保持して釣りの動作を行うと、当該カメラ３０が当該マーキング８を捉えることで、竿全体及びマーキングの各位置における変化を計測するように構成される。 FIG. 1 is a diagram schematically showing an overall configuration of a strain energy measurement system 1 used in the evaluation method of the present invention. As shown in FIG. 1, the measurement system 1 includes a fishing rod 10 having predetermined markings 8 at each position of the rod, a weight 20 attached to one end of the fishing rod 10, and a camera 30 for capturing the marking 8. Consists of. When the operator holds the fishing rod 10 and performs a fishing operation, the camera 30 captures the marking 8 to measure changes in the entire rod and each position of the marking.

なお、計測システム１は、釣竿２０を保持する保持装置をさらに設けるよう構成してもよい。また、計測システム１は、釣竿１０、錘２０、カメラ３０以外の異なる別の装置と組み合わせて構成してもよい。 The measurement system 1 may be configured to further provide a holding device for holding the fishing rod 20. Further, the measurement system 1 may be configured in combination with another device other than the fishing rod 10, the weight 20, and the camera 30.

このようにして、図示の計測システム１は、釣竿を使用した際の、釣竿１０の速度と、加速度と、釣竿の各位置の座標とを検出する。そして、釣竿の各位置の座標に基づく曲率と剛性とから、釣竿１０のひずみエネルギーを算出し、評価を行う。より詳細につき以下述べる。 In this way, the illustrated measurement system 1 detects the speed and acceleration of the fishing rod 10 and the coordinates of each position of the fishing rod when the fishing rod is used. Then, the strain energy of the fishing rod 10 is calculated from the curvature and rigidity based on the coordinates of each position of the fishing rod and evaluated. More details will be described below.

図２を参照して、本発明の一実施形態による評価方法について説明する。本発明の一実施形態による評価方法において、まず、（Ｓ１）において、釣竿１０の各位置の座標に基づく曲率と剛性を検出する。次に、（Ｓ２）において、上述の計測システム１により、釣竿１０を使用した際の、釣竿１０の速度と、加速度とを検出する。ここで、（Ｓ１）よりも（Ｓ２）を先行させてもよいし、同時に行っても構わない。すなわち、（Ｓ３）において、（Ｓ１）及び（Ｓ２）における検出情報を必要とするが、これは検出の順序自体に意義があることを意味するものではなく、適宜順序の変更が可能である。 An evaluation method according to an embodiment of the present invention will be described with reference to FIG. In the evaluation method according to the embodiment of the present invention, first, in (S1), the curvature and the rigidity based on the coordinates of each position of the fishing rod 10 are detected. Next, in (S2), the speed and acceleration of the fishing rod 10 when the fishing rod 10 is used are detected by the measurement system 1 described above. Here, (S2) may precede (S1), or may be performed at the same time. That is, in (S3), the detection information in (S1) and (S2) is required, but this does not mean that the order of detection itself is significant, and the order can be changed as appropriate.

次に、（Ｓ３）において、（Ｓ１）において検出された釣竿１０の上記各情報に基づき、釣竿１０を使用した際の、釣竿１０の竿先から竿尻に至る各位置におけるひずみエネルギー及びその変化を算出する。 Next, in (S3), based on the above information of the fishing rod 10 detected in (S1), the strain energy and its change at each position from the rod tip to the rod bottom of the fishing rod 10 when the fishing rod 10 is used. Is calculated.

そして、（Ｓ３）において算出された該各位置におけるひずみエネルギーの変化に基づき、釣竿を評価する。ここで、釣竿の評価において、該各位置におけるひずみエネルギーの変化に加えて、（Ｓ２）において検出された釣竿１０の速度及び加速度を併せて用いることができる。 Then, the fishing rod is evaluated based on the change in strain energy at each position calculated in (S3). Here, in the evaluation of the fishing rod, in addition to the change in strain energy at each position, the velocity and acceleration of the fishing rod 10 detected in (S2) can be used together.

本発明の一実施形態による評価方法により、釣竿のひずみエネルギーの動的なデータを用いることで、釣竿の現実の使用状態や動き等に応じた、釣竿のより客観的かつ正確な性能評価が可能となる。 By using the dynamic data of the strain energy of the fishing rod by the evaluation method according to the embodiment of the present invention, it is possible to evaluate the performance of the fishing rod more objectively and accurately according to the actual usage state and movement of the fishing rod. It becomes.

本発明の一実施形態による評価方法において、釣竿の各位置におけるひずみエネルギーの算出は、該各位置におけるひずみエネルギーの時系列データの抽出である。このように、釣竿の各位置におけるひずみエネルギーの時系列データを用いることで、釣竿の現実の使用状態や動き等に応じた、釣竿のより客観的かつ正確な性能評価が可能となる。 In the evaluation method according to the embodiment of the present invention, the calculation of the strain energy at each position of the fishing rod is the extraction of the time series data of the strain energy at each position. In this way, by using the time-series data of the strain energy at each position of the fishing rod, it is possible to evaluate the performance of the fishing rod more objectively and accurately according to the actual usage state and movement of the fishing rod.

本発明の一実施形態による評価方法は、前記各位置におけるひずみエネルギーの変化と前記釣竿の使用態様に基づき、釣竿の性能を評価するようにされる。これは、釣竿の使用態様の如何によっては、釣竿の性能評価の観点が異なることを考慮したものである。これにより、釣竿の性能の評価が釣竿の使用態様に沿ってより正確に行うことが可能となる。 In the evaluation method according to the embodiment of the present invention, the performance of the fishing rod is evaluated based on the change in strain energy at each position and the usage mode of the fishing rod. This is in consideration of the fact that the viewpoint of performance evaluation of the fishing rod differs depending on the usage mode of the fishing rod. This makes it possible to evaluate the performance of the fishing rod more accurately according to the usage mode of the fishing rod.

本発明の一実施形態による評価方法において、当該釣竿の使用態様は、釣竿のキャスティング動作である。 In the evaluation method according to the embodiment of the present invention, the usage mode of the fishing rod is a casting operation of the fishing rod.

本発明の一実施形態による評価方法において、当該釣竿の使用態様は、釣竿の引き寄せ動作である。 In the evaluation method according to the embodiment of the present invention, the usage mode of the fishing rod is the pulling operation of the fishing rod.

本発明の一実施形態による評価方法において、当該釣竿の使用態様は、釣竿の取込み動作である。 In the evaluation method according to the embodiment of the present invention, the usage mode of the fishing rod is a fishing rod taking-in operation.

本発明の一実施形態による評価方法は、前記ひずみエネルギーの変化に対する前記釣竿を保持する釣り人への負荷を算出し、該負荷を用いて釣竿を評価するようにされる。これにより、釣り人への負荷を踏まえた釣竿の性能の評価が可能となる。 In the evaluation method according to the embodiment of the present invention, the load on the angler holding the fishing rod with respect to the change in strain energy is calculated, and the fishing rod is evaluated using the load. This makes it possible to evaluate the performance of the fishing rod based on the load on the angler.

本発明の一実施形態による評価方法において、当該ひずみエネルギーの変化は、当該釣竿の各位置におけるひずみエネルギーの蓄積及び解放である。また、本発明の一実施形態による評価方法は、釣竿の一部の位置におけるひずみエネルギーの変化に基づき、釣竿を評価するようにされる。 In the evaluation method according to the embodiment of the present invention, the change in the strain energy is the accumulation and release of the strain energy at each position of the fishing rod. Further, in the evaluation method according to the embodiment of the present invention, the fishing rod is evaluated based on the change in strain energy at a part of the position of the fishing rod.

図３−図８を参照して、本発明の一実施形態による評価方法の例を具体的に説明する。まず、図３ａ、ｂは、２種類の釣竿（竿Ｃ、Ｄ）の使用態様がキャスティング動作である場合の釣竿の各位置におけるひずみエネルギーの時間変化を示し、図３ｃは、２種類の釣竿の使用態様がキャスティング動作である場合のルアー速度の時間変化を示すものである。図３ａ、ｂにおいて、横軸は時間を、縦軸はひずみエネルギーを示す。また、図３ｃにおいて、横軸は時間を、縦軸はルアー速度を示す。 An example of the evaluation method according to the embodiment of the present invention will be specifically described with reference to FIGS. 3 to 8. First, FIGS. 3a and 3b show the time change of strain energy at each position of the fishing rod when the usage mode of the two types of fishing rods (rods C and D) is a casting operation, and FIG. 3c shows the time change of the strain energy of the two types of fishing rods. It shows the time change of the lure speed when the usage mode is a casting operation. In FIGS. 3a and 3b, the horizontal axis represents time and the vertical axis represents strain energy. Further, in FIG. 3c, the horizontal axis represents time and the vertical axis represents lure speed.

また、図３ｄは、２種類の釣竿の使用態様がキャスティング動作である場合の釣竿の総ひずみエネルギーの時間変化を示す。図３ｄにおいて、横軸は時間を、縦軸は総ひずみエネルギーを示す。 Further, FIG. 3d shows the time change of the total strain energy of the fishing rod when the usage mode of the two types of fishing rod is the casting operation. In FIG. 3d, the horizontal axis represents time and the vertical axis represents total strain energy.

図３ａ、ｂに示すように、竿Ｃ、Ｄ共にキャスト動作が開始されてから、竿全体にひずみエネルギーが蓄積されていくが、竿の元端に向かうに従って、より多くのひずみエネルギーが蓄積されていっていることが時系列として示されている。これらから、釣竿の使用態様がキャスティング動作である場合に、どの時間にどの区間で最もひずみエネルギーが蓄積されているかを確認することができる。 As shown in FIGS. 3a and 3b, strain energy is accumulated in the entire rod after the casting operation is started for both rods C and D, but more strain energy is accumulated toward the original end of the rod. It is shown as a time series. From these, when the usage mode of the fishing rod is a casting operation, it is possible to confirm which strain energy is most accumulated in which section at which time.

特に、竿Ｄでは、より早い時間で最も多くのひずみエネルギーが蓄積されており、竿Ｄの釣竿の竿元部分には竿Ｃの釣り竿の竿元部分よりもより多くのひずみエネルギーが蓄積されていくことが判る。ここで、区間とは、竿の竿先から竿元までを適宜１０の区間に分けた場合の竿の各部分を指し、竿先（区間１）から竿元（区間１０）まで及ぶ。 In particular, in rod D, the most strain energy is accumulated in an earlier time, and more strain energy is accumulated in the rod base portion of the fishing rod of rod D than in the rod base portion of the fishing rod of rod C. I know I'm going. Here, the section refers to each part of the rod when the rod tip to the rod base is appropriately divided into 10 sections, and extends from the rod tip (section 1) to the rod base (section 10).

図３ｃに示すように、竿Ｃ、Ｄ共に同じキャスティング速度で釣竿を操作しているが、ルアー速度に関しては、竿Ｄの方が、時間４以降速度が高くなり、時間２０まで継続して速度が高くなっていることが判る。また、図３ｄに示すように、総ひずみエネルギーに関しても、竿Ｄの方がより早く（竿Ｄは時間８付近で最大となり、竿Ｃは時間１１付近で最大となる）総ひずみエネルギーが最大となり、また、その総ひずみエネルギー量もより多く蓄積されていき、その後より多くのエネルギーが解放されていっていることが判る。 As shown in FIG. 3c, both rods C and D operate the fishing rod at the same casting speed, but with regard to the lure speed, the rod D has a higher speed after time 4 and continues to speed until time 20. Can be seen to be higher. Further, as shown in FIG. 3d, with respect to the total strain energy, the rod D has a faster total strain energy (the rod D has the maximum around time 8 and the rod C has the maximum at around time 11). In addition, it can be seen that the total amount of strain energy is also accumulated, and then more energy is released.

このように、図３ａ、ｂ、ｄのひずみエネルギーの時系列変化のデータを参照すると、ひずみエネルギーが蓄積され、その後解放されていく過程で、竿のひずみエネルギーがルアー速度の増加をもたらしていることが判る。 In this way, referring to the time-series change data of the strain energy in FIGS. 3a, b, and d, the strain energy of the rod causes an increase in the lure velocity in the process of accumulating the strain energy and then releasing it. It turns out.

このように、釣竿の使用態様がキャスティング動作である場合に、各竿毎のひずみエネルギーの各区間の時間変化、各竿毎の総ひずみエネルギーの時間変化から、どのような竿であればルアーの速度をより増加させることができるかを的確に予測することが可能となる。 In this way, when the usage mode of the fishing rod is casting operation, from the time change of each section of the strain energy of each rod and the time change of the total strain energy of each rod, what kind of rod is the lure? It is possible to accurately predict whether the speed can be increased further.

本発明の一実施形態による評価方法により、釣竿のひずみエネルギー等の動的なデータを用いることで、釣竿の現実の使用状態や動き等に応じた、釣竿のより客観的かつ正確な性能評価が可能となる。 According to the evaluation method according to the embodiment of the present invention, by using dynamic data such as strain energy of the fishing rod, more objective and accurate performance evaluation of the fishing rod can be performed according to the actual usage state and movement of the fishing rod. It will be possible.

次に、図４を参照して、釣竿の使用態様が釣竿の引き寄せ動作である場合の釣竿全体としてのひずみエネルギーの時間変化を示す。図４において、竿Ａ、竿Ｂそれぞれについて、横軸は時間を、縦軸はひずみエネルギーを示す。時間は引き寄せ開始から終了までを２０分割して時間０−２０で示している。 Next, with reference to FIG. 4, the time change of the strain energy of the fishing rod as a whole when the usage mode of the fishing rod is the pulling operation of the fishing rod is shown. In FIG. 4, for each of rod A and rod B, the horizontal axis represents time and the vertical axis represents strain energy. The time is divided into 20 from the start to the end of attraction and is indicated by time 0-20.

図示のように、引き寄せ動作開始から時間５までの間では、竿Ｂの方がひずみエネルギーが大きく蓄積されかつ一気に解放されていることが分かる。このことから、竿Ａに比べて竿Ｂの方がより早く魚を寄せることができることが分かる。 As shown in the figure, it can be seen that the strain energy of the rod B is larger and released at once from the start of the pulling operation to the time 5. From this, it can be seen that rod B can attract fish faster than rod A.

次に、時間５−８までの間では、竿Ｂの方はひずみエネルギーが蓄積されていく状態となっており、竿Ａの方はひずみエネルギーの蓄積と解放のバランスが取れている。このことから、竿Ｂの方が魚がほとんど動いておらず、竿Ａの方は魚の寄りがほぼ一定で推移していくことが分かる。 Next, until time 5-8, the rod B is in a state of accumulating strain energy, and the rod A has a good balance between the accumulation and release of strain energy. From this, it can be seen that the fish on the rod B hardly moves, and the fish on the rod A stays almost constant.

時間８−１４の間では、竿Ｂの方はひずみエネルギーの蓄積が安定していないことが分かる。他方で、竿Ａの方はひずみエネルギーの蓄積が安定的に行われていることが分かる。このことから、竿Ａの方は一定の速度で魚の寄せを行うことができ、竿Ｂの差を広げて行っていることが分かる。これは、竿Ｂの竿がぶれやすい傾向があり、節間の剛性のつながりが悪いことが原因と考えられる。 It can be seen that the accumulation of strain energy is not stable in the rod B during the time period 8-14. On the other hand, it can be seen that the strain energy is stably accumulated in the rod A. From this, it can be seen that the rod A can pull the fish at a constant speed and widen the difference of the rod B. It is considered that this is because the rod of the rod B tends to shake easily and the rigidity connection between the nodes is poor.

次に、時間１４以降の間では、竿Ａ、竿Ｂ共に竿全体としては同様のひずみエネルギーの解放を示している。 Next, during the time after time 14, both rod A and rod B show the same strain energy release as the rod as a whole.

図５は、竿Ａ、竿Ｂの竿区間７−１１（＃０２節）におけるひずみエネルギーの時間変化を示す。ここで、節とは各竿を４つの区間に分けた場合の各区間を指し、各竿の竿先から竿元まで＃０１節から＃０４節として区分けしている。各節も区間に分けられ、＃０１節は区間１−６、＃０２節は区間７−１１、＃０３節は区間１２−１５、＃０４節は区間１６−１８に分けられている。この区間は均等な間隔で分けてもよいし、竿先に向かうに従ってより狭い間隔で設けるようにしても構わない。図５の場合、竿の変形がしやすい竿先の方がより狭い間隔で区間を設けると良好であるが、その他の方法でもよい。横軸は時間を、縦軸はひずみエネルギーを示す。図示のように、当該竿区間においては、竿Ａ、竿Ｂいずれもひずみエネルギーは、開始から終了まで増加傾向にあることが分かる。また、竿Ａは、区間１０前後を過ぎたあたりから、ひずみエネルギーが竿Ｂのそれよりも大きく蓄積されていっていることが分かる。このように、竿Ａの方が竿を立てて魚を引き寄せる際に安定しており、魚の動きを抑えるのに大きな役割を果たしていることが分かる。また、魚が手元に来てから暴れさせない、釣り人の意図した通り魚を取り込めることが分かった。 FIG. 5 shows the time change of the strain energy in the rod section 7-11 (section # 02) of the rod A and the rod B. Here, the section refers to each section when each rod is divided into four sections, and is divided into sections # 01 to # 04 from the tip of each rod to the base of the rod. Each section is also divided into sections, # 01 section is divided into sections 1-6, # 02 section is divided into sections 7-11, # 03 section is divided into sections 12-15, and # 04 section is divided into sections 16-18. This section may be divided at equal intervals, or may be provided at narrower intervals toward the tip of the rod. In the case of FIG. 5, it is preferable that the rod tip, which is easily deformed, is provided with sections at narrower intervals, but other methods may be used. The horizontal axis shows time and the vertical axis shows strain energy. As shown in the figure, it can be seen that in the rod section, the strain energy of both rod A and rod B tends to increase from the start to the end. Further, it can be seen that the strain energy of the rod A is accumulated more than that of the rod B from around the section 10. In this way, it can be seen that the rod A is more stable when the rod is raised to attract the fish, and plays a major role in suppressing the movement of the fish. It was also found that the fish could be taken in as the angler intended, without letting the fish run wild after they came to hand.

図６は、竿Ａ、竿Ｂの竿区間１６−１８（＃０４節）におけるひずみエネルギーの時間変化を示す。ここで、節とは各竿を４つの区間に分けた場合の各区間を指し、各竿の竿先から竿元まで＃０１節から＃０４節として区分けしている。各節も区間に分けられ、＃０１節は区間１−６、＃０２節は区間７−１１、＃０３節は区間１２−１５、＃０４節は区間１６−１８に分けられている。この区間は均等な間隔で分けてもよいし、竿先に向かうに従ってより狭い間隔で設けるようにしても構わない。図６の場合も、竿の変形がしやすい竿先の方がより狭い間隔で区間を設けると良好であるが、その他の方法でもよい。横軸は時間を、縦軸はひずみエネルギーを示す。開始時は竿は水平状態にあるため、魚を動かすのに重要な枠割を果たす。図示のように、竿Ｂでは、開始直後はひずみエネルギーが一気に増加するが、竿が起き上がってくるに従って、ひずみエネルギーを解放していく様子が示されている。竿Ｂでは、節間の剛性のつながりが悪いため、一時的に魚の寄せが止まってしまう。他方で、図示のように、竿Ａは開始直後はひずみエネルギーの蓄積は大きくないが、ひずみエネルギーの蓄積と解放のバランスがよいため、魚は安定して寄ってくることとなる。 FIG. 6 shows the time change of the strain energy in the rod section 16-18 (section # 04) of the rod A and the rod B. Here, the section refers to each section when each rod is divided into four sections, and is divided into sections # 01 to # 04 from the tip of each rod to the base of the rod. Each section is also divided into sections, # 01 section is divided into sections 1-6, # 02 section is divided into sections 7-11, # 03 section is divided into sections 12-15, and # 04 section is divided into sections 16-18. This section may be divided at equal intervals, or may be provided at narrower intervals toward the tip of the rod. In the case of FIG. 6, it is preferable that the rod tip, which is easily deformed, is provided with sections at narrower intervals, but other methods may be used. The horizontal axis shows time and the vertical axis shows strain energy. At the start, the rod is in a horizontal position, which plays an important role in moving the fish. As shown in the figure, in the rod B, the strain energy increases at a stretch immediately after the start, but it is shown that the strain energy is released as the rod rises. On the rod B, the rigidity connection between the nodes is poor, so that the fish are temporarily stopped. On the other hand, as shown in the figure, the rod A does not accumulate a large amount of strain energy immediately after the start, but the balance between the accumulation and release of the strain energy is good, so that the fish will approach stably.

図５、６から、竿Ｂは、終了まで元節のエネルギー蓄積が多いのに比べ、竿Ａではそのエネルギーが徐々に減少するため、魚が手前に寄ってくるに伴い、竿先の方がより魚の寄せの役割を担うよう移行していくことが分かる。 From FIGS. 5 and 6, the energy of the rod B is large until the end, while the energy of the rod A gradually decreases, so that the rod tip is closer to the front as the fish approaches. It can be seen that the transition will be made to play the role of gathering more fish.

本発明の一実施形態による評価方法により、釣竿のひずみエネルギーの動的なデータを用いることで、釣竿の現実の使用状態や動き等に応じた、釣竿のより客観的かつ正確な性能評価が可能となる。 By using the dynamic data of the strain energy of the fishing rod by the evaluation method according to the embodiment of the present invention, it is possible to evaluate the performance of the fishing rod more objectively and accurately according to the actual usage state and movement of the fishing rod. It becomes.

次に、図７、８を参照して、釣竿の使用態様が釣竿のへらの取込み動作である場合のひずみエネルギーの時間変化及び人の支持力の変化それぞれを示す。図７において、竿Ａ、竿Ｂそれぞれについて、横軸は時間を、縦軸はひずみエネルギーを示す。時間は取込み開始から終了までを１５分割して示している。図８において、竿Ａ、竿Ｂそれぞれについて、横軸は時間を、縦軸は人の支持力を示す。同様に、時間は取込み開始から終了までを１５分割して示している。 Next, with reference to FIGS. 7 and 8, the time change of the strain energy and the change of the bearing capacity of the person when the usage mode of the fishing rod is the operation of taking in the spatula of the fishing rod are shown. In FIG. 7, for each of rod A and rod B, the horizontal axis represents time and the vertical axis represents strain energy. The time is shown by dividing the time from the start to the end of import into 15 parts. In FIG. 8, for each of rod A and rod B, the horizontal axis represents time and the vertical axis represents human bearing capacity. Similarly, the time is shown by dividing the period from the start to the end of the acquisition into 15 parts.

これらの図をみると、竿Ｂでは、ひずみエネルギーの蓄積及び解放がスムーズに行われておらず、人の支持力の変化が大きいことが分かる。他方で、竿Ａでは、ひずみエネルギーの蓄積及び解放が動作全体に亘り効率的に行われており、人の支持力も竿Ｂの凡そ９０％程度で安定的に推移していることが分かる。このように、竿Ｂに比べて竿Ａの方がより早く取込み動作を行うことができ、また、人への負荷も少ないことが分かる。 Looking at these figures, it can be seen that the strain energy is not smoothly accumulated and released in the rod B, and the change in the bearing capacity of the person is large. On the other hand, it can be seen that in the rod A, the strain energy is efficiently stored and released throughout the operation, and the human bearing capacity is stable at about 90% of the rod B. As described above, it can be seen that the rod A can perform the taking-in operation faster than the rod B, and the load on the person is small.
