Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a ski tip structure in which a core is formed from a foamed synthetic resin, and at the same time, upper and lower surface materials and edge materials are integrally molded.

(Prior Art) The tip structure of a conventional ski uses a tip protector made of an aluminum material or the like and having dimensions equivalent to the thickness of the center core of the ski excluding the upper surface material and the thickness of the lower surface material.

(Problem that the invention aims to solve) In this conventional ski tip structure, the thickness of the tip protector is increased, which increases the rigidity, and when the tip of the ski collides with an obstacle. , the impact applied to the skier increases,
This poses a problem for user safety. Therefore, in the present invention, the flexibility of the ski tip structure is improved without reducing the protective effect of the ski tip protector, and the impact when the ski tip collides with an obstacle is reduced. The aim is to improve the safety of skiers by making it easier to absorb.

(Means for Solving the Problems) Therefore, in the present invention, in the tip structure of a ski in which the core is formed of foamed synthetic resin, the lower tip protector member and the upper tip protector member are connected in the vertical direction. The tip structure of the ski is characterized by a spaced apart structure.

(Function) In the tip structure of the ski of this invention, the lower tip protector member and the upper tip protector member are vertically spaced apart from each other, and a foamed synthetic resin is applied to this separated portion. The injection method reduces the stiffness of the tip of the ski, making it easier to absorb shock in the event of a collision, improving skier safety. Furthermore, at the tip of the ski, a synthetic foam resin layer of a different color from the lower tip protector member and the upper tip protector member is disposed between the lower tip protector member and the upper tip protector member. The tip structure of the ski can be made aesthetically superior.

(Example) An example of this invention will be described based on the drawings. First, the first embodiment shown in FIGS. 1 to 3 will be described. The lower tip protector member 2 has an edge portion 3 arranged in a substantially U-shape corresponding to the tip shape of the ski 1. , this edge part 3
A plurality of buried portions 4 are arranged and protruded from the inner upper part (see Fig. 3), and the central portion of the buried portion 4 is bent upward to form a protrusion 5, which is fitted into the upper end of the protrusion 5. A joining part 6 is provided. Further, the upper tip protector member 10 is also provided with a substantially U-shaped edge portion 11 corresponding to the tip shape of the ski 1, and inside this edge portion 11 there are a plurality of embedded portions 12.
A substantially rectangular hole 13 is provided in the center of the buried portion 12, and a protrusion 14 is provided on the outer side of the upper surface of the buried portion 12. Then, the upper tip protector member 10 and the lower tip protector member 2 are assembled into a mold for injecting the foamed synthetic resin, and the lower tip protector member 2 is inserted into the mold to form the tip of the ski 1. By disposing the lower surface material 20 on the lower surface of the upper tip protector member 20 and fitting the hole 13 of the upper tip protector member 10 into the fitting portion 6 of the protrusion 5 of the lower tip protector member 2, the upper tip protector member 10 is A top member 21 is disposed spaced apart from the lower tip protector member 2 and on the protrusion 14 on the upper surface of the upper tip protector member 10. By injecting foamed synthetic resin into the mold assembled in this way, the top material 21, the upper tip protector member 10, the lower tip protector member 2, and the bottom material 20 are integrally molded by the core 22. The tip of the ski 1 is formed.

Next, the second embodiment shown in FIG. 4 will be described. This second embodiment includes the edge portion 3a, buried portion 12a, hole 13a and protrusion 14 shown in FIG.
Upper tip protector member 10 consisting of a.
a and the edge portion 3 shown in FIG.
a. A hole 8a is provided in the buried portion 4a of the lower step protector member 2a, which is composed of the buried portion 4a;
Then, an independent spacer 5a is arranged between the buried parts 4a and 12a, and the fitting parts 6a and 7a arranged at the upper and lower ends of this spacer 5a are connected to the lower tip protector member 2a and the upper tip protector member 1.
Insert it into the holes 8a and 13a of 0a, and
The protector member 2a and the upper step protector member 10a are separated and integrally molded from a foamed synthetic resin.

Next, referring to the third embodiment shown in FIG.
b, a plurality of buried portions 4b protrude from the upper inner side of the edge portion 3b, and a fitting groove 5b is provided on the upper surface of the buried portion 4b. The upper tip protector member 10b is also provided with an approximately U-shaped edge portion 11b corresponding to the shape of the tip of the ski 1, and a plurality of buried portions 12b are protruded from inside this edge portion 11b. A fitting convex portion 6b is provided on the lower surface of the portion 12b, and a protrusion 14b for supporting the top member 21 is provided on the upper surface of the buried portion 12b. Then, the upper step protector member 10b and the lower step protector member 2b are assembled in the mold for injecting the foamed synthetic resin, and the lower surface of the lower step protector member 2b is placed inside the mold to form the tip part. By arranging the upper tip protector member 20 and fitting the fitting convex portion 6b of the upper tip protector member 10b into the fitting groove 5b of the embedded portion 4b of the lower tip protector member 2b, the upper tip protector member 10b is Protrusion 14b is spaced apart from lower tip protector member 2b and on the upper surface of upper tip protector member 10b.
A top member 21 is disposed on the top surface. By injecting foamed synthetic resin into the mold incorporated in this way, the upper surface material 21 and the upper step protector member 1 are formed.
0b, the lower tip protector member 2b and the lower surface member 20 are integrally molded with the core 22 to form the tip portion of the ski 1.

Next, referring to the fourth embodiment shown in FIG. 6, the lower tip protector member 2c has a plurality of buried portions 4c protruding from the upper inner side of the edge portion 3c, and the upper surface of the buried portions 4c extends outwardly. A protrusion 5c is provided in a protruding manner. Also, upper step protector member 1
0c also has a plurality of buried parts 12 inside the edge part 11c.
A protrusion 14 is provided on the upper surface of this buried portion 12c.
c is provided. And the lower tip protector member 2c and the upper tip protector member 10
c are placed one on top of the other, and the buried portions 4c and 12c are fixed with a stopper 6c to separate them, and are integrally molded with foamed synthetic resin.

(Effects) This invention was constructed as claimed in the utility model registration based on the above-mentioned embodiments, and the tip of the ski was made easier to absorb the impact in the event of a collision. It has become possible to improve the safety of skiers.
