Abstract

The ski pole is made of a material having high resistance and being inherently fragile and it is provided, corresponding to the interior or exterior part with at least one structure which extends substantially along the entire length of the ski pole, the structure being made of material resistant to traction, ductile and having good resiliency. In particular this structure may be made of a string (2) which is held in tension between ends (3) and (4) of the ski pole.

Claims

1. A ski pole for skiing made of a single piece (1), having an interior and made of a material having high resistance and inherently fragile which is provided with at least one first structure (2), said structure extending substantially along the entire length of the ski pole, said structure having at least 490N resistance to traction, said structure being ductile and having good resiliency, said structure which extends substantially along the entire length of the ski pole is placed in said interior of said ski pole, wherein said ski pole has two ends (3) and (4) and said first structure is constituted by a string (2), said string being held in tension between said ends (3) and (4) of said ski pole.

2. The ski pole according to claim 1, wherein said ski pole has an exterior and a second structure (5) extends along the entire length of said ski pole and is placed in said exterior of the ski pole.

3. The ski pole according to claim 2, wherein said ski pole has a cross section, said second structure is in the form of thin layers, said layers being substantially coaxial to said cross section of said ski pole.

4. The ski pole according to claim 3, wherein said layers are constituted by thin tubes (6).

5. The ski pole according to claim 1, wherein said string is monoyarn or multiyarn.
