【発明の詳細な説明】 （産業上の利用分野） 本発明はインジェクションスキーの製造方法に関する。[Detailed description of the invention] (Industrial application field) The present invention relates to a method for manufacturing an injection ski.

込んでスキーを形成させる方法がある。(Prior Art) A technique is known in which the cross-sectional shape of the ski in the width direction is formed into a convex part with the center part of the upper surface protruding except for the area where the fastener is attached, thereby improving the strength of the ski itself. Conventional methods for forming the cross-sectional shape in the width direction of skis as described above include deforming the upper surface material of the ski into the final chevron shape using press processing, and then incorporating it into a manufacturing mold to form the ski. There is.

部を形成する方法が知られている。In addition, for injection skis that utilize the foaming pressure of foamable resin, a method is known in which foamable resin is injected into the ski base frame built into a mold and the foaming pressure is used to push up the top material to form a convex part. ing.
（発明が解決しようとする問題点）
しかしながら、上記の従来の製造方法には次にような問
題点がある。(Problems to be Solved by the Invention) However, the above conventional manufacturing method has the following problems.
インジェクションスキーの場合、発泡性樹脂のう発泡圧
で上面材を変形させるのは困難であり、上面材の材質や
肉圧によっては上がらないことがある。また複雑な形状
に発泡圧で押し上げることはほとんど不可能である。In the case of injection skis, it is difficult to deform the top material using the foaming pressure of the foamable resin, and depending on the material and wall pressure of the top material, deformation may not be possible. Furthermore, it is almost impossible to push the foam into a complicated shape using foaming pressure.
従ってインジェクションスキーにおいても上面材をプレ

Ｓ樹脂にはひび割れが生じ易い。屈曲性強化材にＦＲＰ
を用いた場合、ＦＲＰは折れ易くノツチ効果により積層
したＡＢＳ樹脂にもひび割れが生じてしまうという問題
点がある。Therefore, even in injection skis, a method is used in which the upper surface material is previously formed into the final shape by press processing and then foamed resin is injected into the upper surface material. However, if the chevron shape is formed by press working, excessive force will be applied to the top material, resulting in AB
S resin is prone to cracking. FRP for flexibility reinforcement material
When FRP is used, there is a problem that FRP is easily broken and cracks also occur in the laminated ABS resin due to the notch effect.
またプレス加工は上面材を絞り加工するのと同様な作用
があり、山形形状を形成する際に斜面部分の肉圧が薄く
なり大きな変形には無理があるという問題点がある。In addition, press working has a similar effect to drawing the top material, and there is a problem in that when forming a chevron shape, the wall pressure on the sloped portion becomes thinner, making it difficult to achieve large deformation.
プレス加工で上面材を最終形状まで変形させるためには
スキーの種類に応じ、それぞれ金型を用意しなくてはな
らず、その金型も汎用性に乏しく不経済であるという問
題点がある。In order to transform the upper surface material to its final shape by press working, it is necessary to prepare a mold for each type of ski, and these molds also have the problem of being uneconomical and lacking in versatility.
従って本発明は上記問題点を解決すべく、上面材を損な

を提供することを目的とする。Therefore, an object of the present invention is to provide an efficient method for manufacturing an injection ski without damaging the upper surface material, in order to solve the above-mentioned problems.

とを特徴とする。In other words, a foamable resin such as urethane foam is injected into the ski frame frame, and the upper surface material is formed so that the cross section of the ski frame frame in the width direction forms an upwardly convex chevron shape except for the area where the fasteners are attached. In the method for manufacturing an injection ski formed by deforming the ski, a top material made of a resin sheet such as ABS resin or a laminated resin sheet and a flexible reinforcing material such as glass cloth is pressed in advance to form the above-mentioned chevron shape. The upper surface material formed to this intermediate shape and other members constituting the ski frame frame together with the upper surface material are assembled into a mold, and a foamable resin is injected into the ski frame frame. The foaming pressure is used to transform the top material into the final chevron shape, or the resin sheet such as ABS resin and the flexible reinforcing material such as glass cloth constituting the top material are each pre-pressed. After the top material is formed into an intermediate shape up to the chevron shape by processing, it is laminated and bonded with an adhesive, and the members constituting the top material formed to this intermediate shape, and the ski together with the top material. The ski underframe is characterized in that other members constituting the underframe are assembled into a mold, a foamable resin is injected into the ski underframe, and the foaming pressure deforms the top material into the final chevron shape.

。Next, the upper mold 32 is closed, and urethane foam, which is the foamable resin 28, is injected into the space 34 inside the ski frame frame. The top material 10 is pushed up and deformed by the foaming pressure of the foamable resin 28. At this time, the top material 10 is deformed to follow the inner surface shape of the upper die 32, so that the upper surface of the top material 10 can be formed into the final chevron shape shown in FIG.

（発明の効果）
本発明に係るインジェクションスキーの製造方法を用い
ると、上面材を中間形状にまで予め変形しておくので、
発泡性樹脂の注入による変形に際し上面材に無理な力が
加わらないので上面材の損傷を防ぐことが可能となる。(Effects of the Invention) When the injection ski manufacturing method according to the present invention is used, the upper surface material is deformed to an intermediate shape in advance, so that
Since no excessive force is applied to the top material during deformation due to injection of the foamable resin, damage to the top material can be prevented.
また、発泡圧による変形なのでプレスで最終形状まで加

ので上面材の肉圧にムラが生じない。また、予め中間形
状まで変形しておくので、発泡圧による変形であるもの
の複雑な形状にも変形が可能となる。In addition, since the foaming pressure causes deformation, unlike machining to the final shape with a press, no squeezing force is applied to the top material, so there is no unevenness in the thickness of the top material. Further, since the foam is deformed to an intermediate shape in advance, it is possible to deform the foam into a complicated shape even though it is deformed by foaming pressure.
さらに、中間形状に変形させるプレス金型は最終形状の
金型ではないので汎用性に冨み経済的である等の著効を
奏する。Furthermore, since the press mold for deforming into an intermediate shape is not a mold for the final shape, it has great effects such as being highly versatile and economical.
