へ発泡合成樹脂を射出注入してインジェクションスキー
を製造する方法が知られている。Conventionally, in the manufacturing method of the injection molding ski, for example, as shown in FIG. Top surface components such as the fiber-reinforced plastic board and top surface material 10 bonded in advance to the notch portion provided in the mold 3/
Hollow part /2 formed by placing the upper mold and placing the upper mold.
A method of manufacturing an injection ski by injecting a foamed synthetic resin into a ski is known.
しかし、この方法では次のような欠点を有していた。However, this method had the following drawbacks.
剛性の低いものを使用した場合には自重のため容易に撓
みが生じるため、このままで発泡合成樹脂を射出注入す

キーとしては不適当であった。更には、上面構成部材／
／を構成する繊維強化プラスチツク板や上面材を、接着
剤をくなるなどの問題を有していた。If a material with low rigidity is used, it will easily warp due to its own weight, so if foamed synthetic resin is injected as it is, the resin will be squeezed into the warped parts, resulting in a product with no commercial value. , the yield was extremely poor. For this reason, a method has been adopted to prevent deflection due to its own weight by using a highly rigid and firm member for the upper surface component i/, but the Inject VH Nnukey manufactured using this method has a high rigidity as a whole. 2 is too easy and suitable for beginners and intermediates.
It was inappropriate as a key. Furthermore, the upper surface component/
The problem was that the fiber-reinforced plastic board and top surface material that make up the / were damaged by the adhesive.
本発明はかかる欠点に鑑み、生産性が良好で、かつ初級

２によシ形成された中空部２１Ｉ 。To explain the present invention based on the drawings, as shown in Figs. A support member 20 for supporting the upper surface component 2- is installed in the width direction of the lower mold 15, and a fiber-reinforced plastic material/ 3 and then the upper surface material 2/ to constitute the upper surface component 22. Next, after placing the upper mold 23, the lower surface component/l? and a hollow portion 21I formed by the upper surface component 2.

ゲンが可能となる。As described above, in the injection ski manufacturing method of the present invention, in order to use the fiber-reinforced plastic material /3 having an appropriate gap /l as shown in Fig. 3, the foamed synthetic resin is injected after placing it in the mold. By injecting, the foamed synthetic resin passes through this gap /lI and reaches the top material 2/, so that the fiber-reinforced plastic material /3 and the top material 2/ are integrally molded when the foam hardens. . Therefore, there is no need to pre-form the upper surface constituent member in advance as in the past, and the process can be simplified, resulting in cost savings.

級者に向くスキーを供給することができるものである。In addition, in the injection ski manufacturing method according to the present invention, since the support member 20 for supporting the upper surface component is installed on the lower mold, it is possible to prevent the upper surface component from deflecting due to its own weight without increasing the rigidity of the upper surface component. Therefore, it is possible to soften the stiffness of the ski itself, and it is possible to supply skis suitable for beginners and intermediate skiers.

ものなどを用いることもできるものである。In addition, as the fiber-reinforced plastic material /3 having the appropriate gap /4Z described in the examples, it is possible to use commonly called open plain weave cloth, open roving crone, etc., as well as conventional fiber-reinforced plastic board. It is also possible to use a material with holes in it.
更に、実施例図面は省略したが、上面構成部材だけでな
く、下面構成部材用としても適宜な間隙／ｌＩを有する
繊維強化プラスチツク材／３を使用することによυ下面
構成部材の一体成形も可能となる。Furthermore, although the example drawings are omitted, it is possible to integrally mold the υ lower surface component by using fiber-reinforced plastic material /3 having an appropriate gap /lI not only for the upper surface component but also for the lower surface component. It becomes possible.
そのほか、本発明に使用する上面構成部材を支持する支
