ーを接着していたため非常に非能率的であつた。[Detailed explanation of the invention] When manufacturing skis using the conventional polyurethane injection manufacturing method, all parts except the tail protector are set in a mold, and polyurethane is injected from the polyurethane injection port on the tail side of the mold. However, the tail protector was attached after molding, which was extremely inefficient.

ン製法によるスキーに関するものである。 The present invention relates to a ski manufactured using a polyurethane injection method, which has a slit extending from the outside to the inside at the tip of the tip protector, and can be manufactured very efficiently.
次に本考案を図面について説明する。 Next, the present invention will be explained with reference to the drawings.

る。 FIG. 2 shows the molded state of the ski of the present invention. All the parts are set in the mold 11, and the tip of the step protector 10 is provided with a slit 9 extending from the outside to the inside. Polyurethane injected from a polyurethane injection port 12 provided on the tip side of the mold flows into the ski core portion 13 through the slit 9 of the tip protector, and is foamed and hardened to form a ski.

テクター先端部の高い加工精度を必要としない。 As mentioned above, the ski of the present invention does not require attaching some parts such as the tail protector by gluing or the like after molding the ski body using the conventional polyurethane injection manufacturing method.
Since all parts can be set in a mold and molded simultaneously, extremely efficient manufacturing is possible. In addition, the tip of the tip protector has a slit 9, so it is stretchable in the thickness direction, so even if there is variation in the thickness of the tip of the tip protector, the tip protector fits well into the mold, so a product with high dimensional accuracy can be obtained. It is easy to manufacture and does not require high machining accuracy of the tip of the step protector.
