Ski pole

Abstract

An alpine sports pole comprising a tube ( 6 ), a handle ( 4 ) at the upper end ( 8 ) of the tube ( 6 ), and a tip ( 7 ) at the lower end ( 9 ) of the tube ( 6 ), the handle ( 4 ) having a first gripping zone ( 12 ), more particularly for positioning the phalanges of a skier's hand, and a second gripping zone ( 13 ), more particularly for positioning the palm of the skier's hand, the first gripping zone ( 12 ) defining the front (F) of the pole ( 1 ) and the second gripping zone ( 13 ) defining the rear (R) of the pole ( 1 ), the tube ( 6 ) having a substantially circular profiled section over an upper portion ( 17 ) located below the upper end ( 8 ) of the tube ( 6 ) and over a lower portion ( 18 ) located above the lower end ( 9 ) of the tube ( 6 ), and also a profiled section that changes progressively over a central portion ( 19 ) located between the upper portion ( 17 ) and the lower portion ( 18 ). The central portion ( 19 ) of the tube ( 6 ) has a profiled section substantially in the form of a polygon having a single side ( 28 ) oriented toward the front (F) of the pole ( 1 ).

         3 . The pole as claimed in  claim 1  or  2 , wherein just one or a number of the sides ( 28 ) of the polygon of the profiled section ( 23 ) are slightly arcuate, and wherein the side ( 28 ) oriented toward the front (F) of the pole ( 1 ,  2 ,  3 ) is slightly arcuate.  
     
     
         4 . The pole as claimed in any one of the preceding claims, wherein just one or a number of the apices ( 24 ,  26 ,  27 ) of the polygon are rounded.  
     
     
         5 . The pole as claimed in any one of the preceding claims, wherein the polygon of the profiled section ( 23 ) is a triangle, and in that the triangle is an isosceles triangle, and in that the lateral sides ( 29 ,  31 ) of the isosceles triangle have a length greater than the length of the side ( 28 ) oriented toward the front (F) of the pole ( 1 ,  2 ,  3 ).  
     
     
         6 . The pole as claimed in any one of the preceding claims, wherein the side ( 28 ) oriented toward the front (F) of the pole ( 1 ,  2 ,  3 ) has a space for receiving an inscription ( 32 ).  
     
     
         7 . The pole as claimed in any one of the preceding claims, which comprises a hollow longitudinal tube with a circumferential wall that in cross section from the inside toward the outside, respectively, at least one layer of a first material based on carbon fibers ( 37 ,  38 ), at least one layer of a second material based on aramide fibers ( 39 ), and at least one layer of a third material based on carbon fibers ( 41 ).  
     
     
         8 . The pole as claimed in  claim 7 , wherein in cross section from the inside toward the outside, respectively, the wall comprises a first crossworked fabric based on carbon fibers ( 37 ), a unidirectional fabric based on carbon fibers ( 38 ), a fabric based on aramide fibers ( 39 ), and a second crossworked fabric based on carbon fibers ( 41 ).  
     
     
         9 . The pole as claimed in  claim 8 , wherein the fabric based on aramide fibers ( 39 ) is a unidirectional fabric or a crossworked fabric.
