Description

本発明は、長手方向に沿う一方側の端面を滑走面とする長尺板状の板状部と、板状部の長手方向の一端側に形成された凹凸形状を有する凹凸部とを備え、凹凸部が、凹凸部の凸部が一方側に凸となる状態で、滑走面よりも板状部の他方側の端面寄りに形成され、凹凸形状が、板状部の厚み方向から見て鋸状に形成されたアイススケート靴用のブレードに関する。   The present invention includes a long plate-shaped plate-like portion having one end surface along the longitudinal direction as a sliding surface, and a concave-convex portion having a concave-convex shape formed at one longitudinal end of the plate-like portion. The uneven portion is formed closer to the end face on the other side of the plate portion than the sliding surface in a state where the convex portion of the uneven portion is convex to one side, and the uneven shape is sawed in the thickness direction of the plate portion. The present invention relates to a blade for ice skating shoes formed in a shape.

かかるアイススケート靴用のブレードは、フィギュアスケート用のスケート靴等に用いられ、ブレードの凹凸部がスケート靴のつま先側に位置するようにスケート靴に取り付けて使用するものである。ブレードの凹凸部は、通常の氷面滑走時においては氷面に接触することなく、回転ジャンプの踏み切りにおいて回転ジャンプの起点となる氷面の適切な位置を突くために使用される。   Such blades for ice skating shoes are used for skating shoes for figure skating, etc., and are used by attaching to skating shoes such that the uneven portions of the blades are located on the toe side of the skating shoes. The concave and convex portions of the blade are used to hit an appropriate position on the ice surface that is the starting point of the rotational jump at the takeoff of the rotational jump without touching the ice surface during normal gliding.

具体的には、助走をつけた状態で、スケート靴のつま先側に位置する鋸状の凸凹部を氷面の適切な位置に突いて踏み切ることにより、助走のエネルギーを利用して回転ジャンプを行うために必要となる跳躍力と回転力とを得ることができる。これにより、「トゥジャンプ」と言われる「ルッツ」、「フリップ」、「トゥループ」の３種類の回転ジャンプを行うことができる。   Specifically, in a state in which the runway is on, a rotational jump is performed by using the energy of the runway by hitting the saw-like concave and convex portion located on the toe side of the skate shoe to an appropriate position on the ice surface and stepping off. The jumping force and the turning force required for the above can be obtained. As a result, three types of rotational jumps called “toe jump”, “lutz”, “flip”, and “to loop” can be performed.

このようなアイススケート靴用のブレードとして、滑走面のつま先側に、滑走面に沿って一列に並んだ鋸状の凹凸形状を有する凹凸部を備えたものがある（例えば、特許文献１参照）。特許文献１に記載の鋸状の凹凸形状は、滑走面側から見ると複数の凸部と凹部とが平行に並ぶように形成されている。   As such a blade for ice skating shoes, there is a blade provided with a concave and convex portion having a saw-like concave and convex shape arranged in a line along the sliding surface on the toe side of the sliding surface (for example, see Patent Document 1). . The saw-like uneven shape described in Patent Literature 1 is formed such that a plurality of convex portions and concave portions are arranged in parallel when viewed from the sliding surface side.

実開昭６２−２９１０２号公報Japanese Utility Model Publication No. Sho 62-29102

近年、フィギュアスケートの技術が高度化しており、フィギュアスケートの競技大会等で高い評価を得るためには、４回転ジャンプなどのレベルの高いトゥジャンプを行う必要がある。そのため、トゥジャンプの踏み切りの際に、より大きな跳躍力と回転力とを安定して得ることが必要になっている。   In recent years, the art of figure skating has been advanced, and it is necessary to perform a high-level toe jump such as a quadruple jump in order to obtain a high evaluation in a competition of figure skating or the like. For this reason, it is necessary to stably obtain a larger jumping force and rotational force when taking off a toe jump.

そして、より大きな跳躍力と回転力とを安定して得るためには、トゥジャンプを行う際、助走速度を上げた状態で氷面の適切な位置に凹凸部を突いて踏み切る必要があるが、そのように助走速度を上げた状態では凹凸部と接触する氷面に大きな力がかかるため、凹凸部の氷面への突きが十分ではなく凹凸部が十分に氷面を捉えられていない場合、凹凸部が氷面の適切な位置からずれてしまうことがある。   And, in order to stably obtain a larger jumping power and rotational force, when performing a toe jump, it is necessary to push off the uneven part at an appropriate position on the ice surface with the approach speed increased, In such a state where the approach speed is increased, a large force is applied to the ice surface in contact with the uneven portion, so if the uneven portion does not sufficiently hit the ice surface and the uneven portion does not sufficiently catch the ice surface, The irregularities may be shifted from an appropriate position on the ice surface.

このように、氷面の適切な位置に突きさした凹凸部が適切な位置からずれてしまった場合、助走のエネルギーをうまく利用することができず、十分な跳躍力と回転力とを得られなくなることに加え、使用者はトゥジャンプの踏み切り直後やトゥジャンプの着地時にバランスを崩して転倒し、負傷する虞があった。   In this way, when the uneven portion protruded to the appropriate position on the ice surface is deviated from the appropriate position, the energy of the run-up cannot be utilized properly, and sufficient jumping power and rotational force can be obtained. In addition to the disappearance, the user may lose his balance immediately after the crossing of the toe jump or at the time of the landing of the toe jump, and fall, resulting in injury.

本発明は、上記実情に鑑みてなされたものであって、その目的は、トゥジャンプを行うために必要となる跳躍力と回転力とを安定して得ることができつつ、使用者の転倒を防止することができるアイススケート靴用のブレードを提供する点にある。   The present invention has been made in view of the above circumstances, and an object of the present invention is to stably obtain a jumping force and a rotating force necessary for performing a toe jump, and to prevent a user from falling down. It is an object to provide a blade for ice skates that can be prevented.

〔第１実施形態〕
以下図面に基づいて、本発明のアイススケート靴用のブレードについて説明する。
図１に、本発明に係るアイススケート靴用のブレードを備えたアイススケート靴１００を示す。図１に示すように、本発明に係るアイススケート靴用のブレードとしてのブレード部１０は、アイススケート靴１００のブーツ部２０の底部に取り付けられている。 [First Embodiment]
Hereinafter, a blade for ice skating shoes of the present invention will be described with reference to the drawings.
FIG. 1 shows an ice skating shoe 100 provided with a blade for an ice skating shoe according to the present invention. As shown in FIG. 1, a blade portion 10 as a blade for ice skating shoes according to the present invention is attached to the bottom of a boot portion 20 of an ice skating shoe 100.

ブレード部１０は、長手方向に沿う一方側の端面を滑走面１とする長尺板状の板状部２と、板状部２の長手方向の一端側に形成された凹凸形状を有する凹凸部３とを備えている。また、ブレード部１０には、板状部２及び凹凸部３を、ブーツ部２０の底部に取り付けるための支柱部５が設けられている。   The blade portion 10 includes a long plate-shaped plate portion 2 having a sliding surface 1 at one end surface along the longitudinal direction, and a concave-convex portion having a concave-convex shape formed at one longitudinal end of the plate portion 2. 3 is provided. Further, the blade portion 10 is provided with a support portion 5 for attaching the plate portion 2 and the uneven portion 3 to the bottom of the boot portion 20.

ブレード部１０は、ブレード部１０の長手方向をアイススケート靴１００のつま先部２０ａとかかと部２０ｂとを結ぶ直線に沿う方向に一致させ、かつ、滑走面１である長手方向に沿う一方側の端面がブーツ部２０の底部と反対側に位置するように、ブーツ部２０の底部に取り付けられている。また、凹凸部３が形成されたブレード部１０の長手方向の一端側が、アイススケート靴１００のつま先部２０ａ側に位置するように、ブーツ部２０の底部に取り付けられている。   The blade portion 10 is arranged such that the longitudinal direction of the blade portion 10 coincides with the direction along a straight line connecting the toe portion 20a and the heel portion 20b of the ice skating shoe 100, and one end face along the longitudinal direction which is the sliding surface 1 Is mounted on the bottom of the boot portion 20 so that is located on the side opposite to the bottom of the boot portion 20. Further, the blade portion 10 on which the uneven portion 3 is formed is attached to the bottom of the boot portion 20 such that one end side in the longitudinal direction of the blade portion 10 is located on the toe portion 20a side of the ice skate 100.

凹凸部３は、凹凸部３の凸部３aが板状部２の一方側に凸となる状態で、滑走面１よりも板状部２の他方側の端面６寄りに形成されている。つまり、凹凸部３は、凸部３ａがブレード部１０において滑走面１が形成されている一方側に突出する状態で、滑走面１よりも滑走面１と反対側の端面６寄りに形成されている。   The uneven portion 3 is formed closer to the end surface 6 on the other side of the plate portion 2 than the sliding surface 1 in a state where the convex portion 3a of the uneven portion 3 is protruded to one side of the plate portion 2. That is, the uneven portion 3 is formed closer to the end surface 6 on the side opposite to the sliding surface 1 than the sliding surface 1 in a state where the convex portion 3a protrudes to one side of the blade portion 10 where the sliding surface 1 is formed. I have.

板状部２は、板状部２の長手方向の他端側であるかかと部２０ｂ側から長手方向の一端側であるつま先部２０ａ側に向かって、板状部２の厚み方向から見て滑走面１側に凸となるカーブが形成されている。特に、板状部２の一端側であるつま先部２０ａ側の凹凸部３に近接する部分では、板状部２の厚み方向から見て滑走面１側に凸となる曲率が大きく形成されて設けられている。このように、板状部２の一端側が形成されているので、板状部２の一端側に形成された凹凸部３が滑走面１よりも滑走面１と反対側の端面６寄りに形成されることになる。よって、通常の氷面滑走時には、凹凸部３が氷面から離間する状態で、滑走面１のみを氷面に接触させて氷上を滑走することができる。   The plate-shaped portion 2 slides from the heel portion 20b side, which is the other end side in the longitudinal direction of the plate-shaped portion 2, to the toe portion 20a, which is one end side in the longitudinal direction, as viewed from the thickness direction of the plate-shaped portion 2. A convex curve is formed on the surface 1 side. In particular, in a portion close to the uneven portion 3 on the toe portion 20a side, which is one end side of the plate-shaped portion 2, a curvature that is convex toward the sliding surface 1 side when viewed from the thickness direction of the plate-shaped portion 2 is provided so as to be large. Have been. As described above, since one end side of the plate-shaped portion 2 is formed, the uneven portion 3 formed on one end side of the plate-shaped portion 2 is formed closer to the end surface 6 on the opposite side to the sliding surface 1 than the sliding surface 1. Will be. Therefore, during normal ice gliding, it is possible to slide on the ice by bringing only the gliding surface 1 into contact with the ice surface in a state where the uneven portion 3 is separated from the ice surface.

次に、凹凸部３の凹凸形状について図１から図３に基づいて詳細に説明する。図２は凹凸部３の斜視図であり、図３は凹凸部３の正面図である。図１に示すように、凹凸部３の凹凸形状は、板状部２の厚み方向から見て鋸状に形成されている。そして、図２及び図３に示すように、凹凸部３は、複数の錐状体７で形成され、錐状体７の頂部７ａを凸部３ａとする状態で長手方向に並設されて形成されている。   Next, the uneven shape of the uneven portion 3 will be described in detail with reference to FIGS. FIG. 2 is a perspective view of the uneven portion 3, and FIG. 3 is a front view of the uneven portion 3. As shown in FIG. 1, the uneven shape of the uneven portion 3 is formed in a saw-like shape when viewed from the thickness direction of the plate-shaped portion 2. As shown in FIGS. 2 and 3, the concavo-convex portions 3 are formed by a plurality of cones 7, and are formed side by side in the longitudinal direction with the tops 7 a of the cones 7 serving as the protrusions 3 a. Have been.

つまり、凹凸部３は複数の錐状体７で形成され、かつ、複数の錐状体７の頂部７ａが凸部３ａとなるように形成されている。この錐状体７の頂部７ａは、ブレード部１０において滑走面１が形成されている一方側に突出する状態で形成されている。よって、アイススケート靴１００を用いて、通常の氷面滑走を行っている場合には、その錐状体７の頂部７ａが氷面から離間しつつ、氷面に向かって突出する状態となる。   That is, the concavo-convex portion 3 is formed by the plurality of cones 7, and the tops 7 a of the plurality of cones 7 are formed to be the protrusions 3 a. The top 7a of the conical body 7 is formed so as to protrude to one side of the blade section 10 where the sliding surface 1 is formed. Therefore, when the normal ice surface is slid using the ice skating shoes 100, the top portion 7a of the cone 7 protrudes toward the ice surface while being separated from the ice surface.

そして、凹凸部３を板状部２の厚み方向から見た凹凸部３の凹部３ｂから凸部３ａまでの突出寸法Ｙ（図１参照）は、板状部２の厚さＸの０．５〜２．０倍の寸法で形成されている。これにより、凹凸部３が十分な強度を有するものとなり、凹凸部を氷面に突きさす際にも破損することを防止することができる。   The projection dimension Y (see FIG. 1) from the concave portion 3b to the convex portion 3a of the uneven portion 3 when the uneven portion 3 is viewed from the thickness direction of the plate portion 2 is 0.5 of the thickness X of the plate portion 2. It is formed with a size of up to 2.0 times. Thereby, the uneven portion 3 has sufficient strength, and it is possible to prevent the uneven portion 3 from being damaged even when the uneven portion 3 is pressed against the ice surface.

図３に示すように、錐状体７は、板状部２の厚さＸを底面の厚み方向の長さとする四角錘状の錐状体７で構成されている。この錐状体７の頂部７ａが、氷面により深く突きさすことができるように尖っているので、ブレード部１０が装着されたアイススケート靴１００の使用者は、トゥジャンプの踏み切りの際に、アイススケート靴１００のつま先部２０ａ側に設けられた複数の錐状体７の頂部７ａを、氷面の適切な位置により深く氷面の適切な位置により深くかつ正確に突きさすことができる。   As shown in FIG. 3, the conical body 7 is configured by a quadrangular pyramid-shaped conical body 7 having the thickness X of the plate-shaped portion 2 in the thickness direction of the bottom surface. Since the top 7a of the cone 7 is sharpened so as to be able to protrude deeper into the ice surface, the user of the ice skate 100 equipped with the blade 10 can take a The tops 7a of the plurality of cones 7 provided on the toe 20a side of the ice skate 100 can be pushed deeper and more accurately at an appropriate position on the ice surface and deeper and more accurately at an appropriate position on the ice surface.

これにより、トゥジャンプを行うための助走速度を上げた場合でも、トゥジャンプの起点となる氷面の適切な位置に突きさした凹凸部３の錐状体７が、氷面の適切な位置からずれることを防止することができるので、助走のエネルギーを利用してトゥジャンプを行うために必要となる大きな跳躍力と回転力とを安定して得ることができつつ、使用者が転倒することを防止することができる。   As a result, even when the approach speed for performing the toe jump is increased, the conical body 7 of the uneven portion 3 protruding to an appropriate position on the ice surface serving as a starting point of the toe jump is moved from the appropriate position on the ice surface. Since it is possible to prevent the user from falling down, it is possible to stably obtain the large jumping power and rotational force required for performing the toe jump using the energy of the approaching run, and to prevent the user from falling down. Can be prevented.
