Description

本発明は、アイススケート靴用ブレードに関するものである。 The present invention relates to ice skate blades.

従来から、例えば特許文献1に開示されるようなアイススケート靴(以下、従来例)が提案されている。 Conventionally, ice skates such as those disclosed in Patent Document 1 (hereinafter, the conventional example) have been proposed.

この従来例は、スケート靴本体の底部にブレードを設けたものであり、このブレードは、スケート靴本体の底部に取り付けられる取付部と、この取付部に垂設され下端部にエッジを有する刃板部とから成るものである。 In this conventional example, a blade is attached to the bottom of the skate body, and the blade consists of an attachment part that is attached to the bottom of the skate body and a blade plate part that is suspended from the attachment part and has an edge at the lower end.

ところで、この従来例は、別々に設けられた取付部と刃板部とを溶接して連結されたものが一般的であるが、継続使用によりこの溶接部分が破断したり変形したりするなど強度上の問題点がある。 In the conventional example, the attachment section and the blade plate section are generally connected by welding, which poses strength problems such as the welded section breaking or deforming with continued use.

そこで、従来において、この取付部と刃板部とを切削加工により一体成形したものが提案されており、従来例に比して強度を有するものであるが、製造性が悪く高価となってしまう。 In the past, a proposal was made to mold the mounting section and the blade plate section as one piece by cutting. This is stronger than the conventional example, but it is difficult to manufacture and expensive.

本実施例は、スケート靴本体20の底部に取り付けられる取付部1と、この取付部1に垂設され下端部にエッジ2aを有する刃板部2とから成るアイススケート靴用ブレードである。 This embodiment is an ice skate blade consisting of an attachment part 1 that is attached to the bottom of the skate body 20, and a blade plate part 2 that is suspended from this attachment part 1 and has an edge 2a at its lower end.

尚、本実施例ではアイススケート靴用ブレードとして、フィギュアスケート靴用のブレードが採用されているが、その他の競技(アイスホッケーやスピードスケート)用のものでも良いなど、本実施例の特性を発揮する構成であれば適宜採用し得るものである。 In this embodiment, a figure skate blade is used as the ice skate blade, but it can also be used for other sports (ice hockey, speed skating, etc.) as long as it has the characteristics of this embodiment.

具体的には、本実施例は、図1,2に図示したようにスケート靴本体20の底面前後位置に止着部材10(ビス)を介して取り付けられる板状の取付部1(ソールプレート及びヒールプレート)と、この各取付部1に連設される板状の連設部2’(支柱板)を備えた刃板部2とで構成されており、刃板部2の下縁部左右位置には、側断面視円弧状の溝を介した内外一対のエッジ2a(アウトサイドエッジ及びインサイドエッジ)が設けられ、刃板部2の先端部には山部と谷部が交互に連続するトウピック2bが設けられている。 Specifically, as shown in Figs. 1 and 2, this embodiment is composed of a plate-shaped mounting portion 1 (sole plate and heel plate) that is attached to the bottom front and rear positions of the skate body 20 via fastening members 10 (screws), and a blade plate portion 2 equipped with a plate-shaped connecting portion 2' (support plate) that is connected to each mounting portion 1. A pair of inner and outer edges 2a (outside edge and inside edge) are provided at the left and right positions of the lower edge of the blade plate portion 2 via a groove that is arc-shaped in side cross section, and a toe pick 2b with alternating peaks and valleys is provided at the tip of the blade plate portion 2.

また、取付部1と刃板部2とは下記の金属材料の鋳造(ロストワックス精密鋳造)により一体形成されている。 The mounting portion 1 and the blade plate portion 2 are integrally formed by casting (lost wax precision casting) using the following metal material.


鉄98(Fe)重量%以上,炭素(C)0.17重量%~0.25重量%,シリコン・ケイ素(Si)0.1重量%~0.3重量%,マンガン(Mn)0.62重量%~0.83重量%,クロム(Cr)0.85重量%~1.25重量%及びモリブデン(Mo)0.13重量%~0.25重量%を含有した金属材料。
A metallic material containing 98% or more by weight of iron (Fe), 0.17% to 0.25% by weight of carbon (C), 0.1% to 0.3% by weight of silicon (Si), 0.62% to 0.83% by weight of manganese (Mn), 0.85% to 1.25% by weight of chromium (Cr), and 0.13% to 0.25% by weight of molybdenum (Mo).

実際に種々試したところ、下記の成分を追加配合しても耐久性に秀れた実用品として適することを確認している。 After various tests, we confirmed that the product is suitable as a practical product with excellent durability even when the following ingredients are added.


リン(P)0.025重量%以下,サルファ(S)0.025重量%以下,ニッケル(Ni)0.2重量%以下及び銅(Cu)0.2重量%以下の成分。
The components are phosphorus (P) 0.025% by weight or less, sulfur (S) 0.025% by weight or less, nickel (Ni) 0.2% by weight or less, and copper (Cu) 0.2% by weight or less.

尚、本実施例では、取付部1と刃板部2から成るアイススケート靴用ブレードをロストワックス鋳造法により得ているが、これに限らず、例えば砂型鋳造法や消失鋳造法などでも良いなど、本実施例の特性を発揮する鋳造法であれば適宜採用するものである。 In this embodiment, the ice skate blade consisting of the mounting portion 1 and the blade plate portion 2 is obtained by the lost wax casting method, but this is not limiting, and any suitable casting method can be used as long as it exhibits the characteristics of this embodiment, such as sand casting or lost wax casting.

以下、本実施例に係るアイススケート靴用ブレードの製造工程について図3に基づいて説明する。 The manufacturing process for the ice skate blade of this embodiment will be described below with reference to FIG. 3.

ロストワックス精密鋳造により鋳造製品を得る。 Cast products are obtained using lost wax precision casting.

具体的には、先ず、図面よりロウ模型用の金型を製作する。 Specifically, first, a metal mold for the wax model is created based on the blueprint.

続いて、上記金型でロウ模型を製作する。 Next, a wax model is made using the above mold.

続いて、上記ロウ模型に鋳造の際の湯道を設置(ロウ模型の組立)する。 Next, the runner for casting is installed in the wax model (assembly of the wax model).

続いて、上記湯道が設置されたロウ模型に鋳型用セラミック材を塗布(コーティング)する。 Next, the wax model with the runner installed is coated with ceramic material for the mold.

続いて、上記セラミック材が塗布された鋳型を湯道の開口が下となる逆さ状態とし、この状態で蒸気窯で溶かしてロウを排出させて除去(脱ロウ)する。 Then, the mold coated with the ceramic material is turned upside down with the opening of the runner facing downwards, and in this state it is melted in a steam kiln to drain and remove the wax (dewaxing).

続いて、上記セラミック材が塗布された鋳型を焼成(1000℃×1時間)する。 Next, the mold coated with the ceramic material is fired (1000°C x 1 hour).

続いて、上記焼成された鋳型に鋳造(1650℃の上記金属材料(溶融メタル)を鋳込み)する。 Then, casting (pouring the above metal material (molten metal) at 1650°C) into the fired mold is performed.

続いて、上記鋳込みされた鋳型を自然冷却させ、ハンマーで叩いて崩壊させて鋳物を取り出す。 Next, the mold is cooled naturally and then struck with a hammer to collapse it and remove the casting.

続いて、鋳物の製品部を湯道から切り離す。 Next, the product part of the casting is separated from the runner.

続いて、製品部をグラインダーなどで仕上げる(鋳造で出来た穴(ガスホール穴など)を溶接(同じ材質の溶接棒)で埋めて、グラインダーで慣らしたり、バリや凹凸などを除去する)と、鋳造製品が完成する。 Next, the product part is finished using a grinder, etc. (holes made during casting (such as gas holes) are filled with welding (a welding rod made of the same material), and the product is smoothed out with a grinder, and burrs and irregularities are removed), and the cast product is complete.

次に、前述したロストワックス精密鋳造により得た鋳造製品を加工する。 Next, the cast product obtained by the lost wax precision casting described above is processed.

具体的には、先ず、複数の鋳造製品を熱処理炉(加熱装置)に入れて焼鈍(550~650℃)して空冷する。 Specifically, first, multiple cast products are placed in a heat treatment furnace (heating device), annealed (550-650°C), and then air-cooled.

続いて、上記焼鈍した鋳造製品を矯正(プレス矯正で変形を補正)する。鍛造後は熱変形で曲がっている為、取付部1と刃板部2(連設部2’)とをT字状に整える修正と、エッジ2aを平らにする修正をプレスで行う。 Next, the annealed cast product is straightened (deformation is corrected by press straightening). Since it is bent due to thermal deformation after forging, correction is performed by straightening the attachment part 1 and the blade plate part 2 (connected part 2') into a T-shape and by flattening the edge 2a using a press.

続いて、上記プレス矯正した複数の鋳造製品を熱処理炉に入れて熱処理(850~900℃)して油冷を行い(一次焼入れ)、更に、この一次焼入れした複数の鋳造製品を熱処理炉に入れて熱処理(800~850℃)して油冷を行い(二次焼入れ)、更に、この二次焼入れした複数の鋳造品を熱処理炉に入れて熱処理(150~200℃)して空冷を行う(焼戻)。 Then, the multiple cast products that have been press-corrected are placed in a heat treatment furnace and heat-treated (850-900°C) and oil-cooled (primary quenching), and the multiple cast products that have been primarily quenched are placed in a heat treatment furnace and heat-treated (800-850°C) and oil-cooled (secondary quenching), and the multiple cast products that have been secondary quenched are placed in a heat treatment furnace and heat-treated (150-200°C) and air-cooled (tempering).

続いて、上記焼入れ及び焼戻した鋳造製品の前面をニッケルクロムでメッキ処理(防錆目的)する。 Then, the front surface of the hardened and tempered cast product is plated with nickel chrome (for rust prevention purposes).

続いて、上記メッキ処理した鋳造製品の刃板部2における滑走面(底面)にエッジ2aを設ける刃付け研磨(専用機での砥石グラインダーで刃付け研磨)して完成する。 Next, the plated cast product is polished to provide an edge 2a on the sliding surface (bottom surface) of the blade plate portion 2 (polished with a special grinding wheel) to complete the process.

本出願人は以上のようにして製造されたアイススケート靴用ブレードは、以下の強度を有することを確認している。 The applicant has confirmed that the ice skate blade manufactured in the manner described above has the following strength:

引張強さ98kgf/mm以上
伸び15%以上
絞り42以上
硬さ(HRC35~45)
Tensile strength 98kgf/mm2 or more Elongation 15% or more Reduction of area 42 or more Hardness (HRC 35-45)

本実施例は上述のように構成したから、取付部1と刃板部2とは金属材料の鋳造により一体形成されているから、例えば継続使用により取付部1と刃板部2との連設部位が破断したり変形したりせず強度及び耐久性に優れ、しかも、様々な形状(柄・模様・凹凸などの三次元形状)を簡易に形成することができ、量産性に秀れてコスト安に製造できることになる。 Since this embodiment is constructed as described above, the attachment portion 1 and the blade plate portion 2 are integrally formed by casting a metal material, and therefore the connecting portion between the attachment portion 1 and the blade plate portion 2 is not likely to break or deform due to continuous use, and has excellent strength and durability. Moreover, various shapes (three-dimensional shapes such as patterns, designs, and uneven surfaces) can be easily formed, and the product can be mass-produced at low cost.

また、本実施例の鋳造はロストワックス精密鋳造であるから、薄い板状の取付部1及び刃板部2を精度良く製造することができる。 In addition, the casting in this embodiment is a lost wax precision casting, so the thin plate-like mounting portion 1 and blade plate portion 2 can be manufactured with high precision.

また、本実施例は、金属材料として、鉄98重量%以上,炭素0.17重量%~0.25重量%,ケイ素0.1重量%~0.3重量%,マンガン0.62重量%~0.83重量%,クロム0.85重量%~1.25重量%及びモリブデン0.13重量%~0.25重量%を含有した金属材料を採用したから、高強度のアイススケート靴用ブレードを製造することができる。 In addition, this embodiment uses a metal material containing 98% or more by weight of iron, 0.17% to 0.25% by weight of carbon, 0.1% to 0.3% by weight of silicon, 0.62% to 0.83% by weight of manganese, 0.85% to 1.25% by weight of chromium, and 0.13% to 0.25% by weight of molybdenum, making it possible to manufacture high-strength ice skate blades.

尚、本発明は、本実施例に限られるものではなく、各構成要件の具体的構成は適宜設計し得るものである。 The present invention is not limited to this embodiment, and the specific configuration of each component can be designed as appropriate.
