BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improved ski pole molding material.

[0002]

2. Description of the Related Art Conventionally, aluminum has been mainly used as a material for forming ski poles from the viewpoints of lightness, workability and low cost.

By the way, for a ski pole, lightness is the most important performance factor, but in addition, shock absorption (elasticity) and durability are also important performance factors. However, since the conventional ski pole uses aluminum, it cannot be said to be sufficient in terms of impact absorption and durability, and a new molding material satisfying these performance factors has been demanded.

The present invention has responded to such conventional demands, and an object thereof is to provide a ski pole which is not only lightweight but also excellent in shock absorption and durability.

[0005]

The ski pole 1 according to the present invention comprises carbon graphite C as a molding material, preferably carbon containing 93 to 99% by weight of carbon and 1 to 7% by weight of graphite (glass fiber). It is characterized in that it is formed into an inner hollow by using graphite C.

[0006]

According to the ski pole 1 of the present invention, since carbon graphite containing carbon and graphite is used as the forming material, a proper elasticity is obtained as the material performance of the carbon graphite. Therefore, the shock absorption is enhanced and the durability is enhanced. Also,
By including 93 to 99 weight percent carbon and 1 to 7 weight percent graphite, in particular:
The temperature resistance is enhanced, and the impact absorption and durability are prevented from lowering even at low temperatures, and the performance elements required for ski poles are sufficiently satisfied.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, preferred embodiments according to the present invention will be described in detail with reference to the drawings.

FIG. 1 shows a longitudinal section of a ski pole according to the present invention, and FIG. 2 shows a section taken along the line AA in FIG.

First, the ski pole 1 is formed to have a hollow interior, and the diameter is gradually reduced toward the tip. Since the ski pole 1 is processed by being narrowed down at the time of molding, the thickness becomes larger on the smaller diameter side.

Carbon graphite C is used as a material for forming the ski pole 1. Carbon graphite contains 93 to 99 weight percent, preferably 96 weight percent carbon, and 1 to 7 weight percent, preferably 4 weight percent glass fiber, graphite. With such a blending ratio of components, not only light weight but also appropriate elasticity is obtained, shock absorption and durability are enhanced, and especially heat resistance is enhanced, and shock absorption even at low temperature. Also, deterioration of durability is suppressed.

Therefore, the performance element required for a ski pole which is used at a low temperature and is frequently impacted in the longitudinal direction at the time of use is sufficiently satisfied, and the ski pole can be used as an optimum molding material.

FIG. 3 shows a finished ski pole, that is, a stock S. The stock S has a grip portion 3 attached to the upper end of the ski pole 1, a ring portion 4 attached to the lower portion of the ski pole 1, and a pointed portion 5 provided at the lower end.

The embodiment has been described in detail above.
The present invention is not limited to such an embodiment.
For example, the composition ratio of carbon graphite is not limited to the exemplified values, and can be arbitrarily changed, and it does not hinder the case of mixing other components. Other details,
The shape and the like can be arbitrarily changed without departing from the gist of the present invention.

[0014]

As described above, since the ski pole according to the present invention uses carbon graphite as a forming material,
In addition to being lightweight, it is possible to greatly improve shock absorption and durability, and for ski poles that are used at low temperatures and are frequently subjected to shocks in the longitudinal direction during use, these types are also available at low temperatures. It has a remarkable effect that the performance is not deteriorated.
