Abstract:
PCT No. PCT/FI94/00050 Sec. 371 Date Sep. 1, 1995 Sec. 102(e) Date Sep. 1, 1995 PCT Filed Feb. 3, 1994 PCT Pub. No. WO94/17874 PCT Pub. Date Aug. 18, 1994The invention relates to a pole shaft for a cross-country ski pole. Longitudinal and transverse fiber layers are used for providing a hollow shaft, whose cross section changes progressively downwards into a droplet shape and, below the mid-way point of a shaft, the length of a droplet shape in relation to its width increases while the cross-sectional area diminishes. By virtue of the droplet shape, the pole can be given more rigidity in skiing direction, whereby the bottom end of a pole can be made lighter while improving the aerodynamics of a pole.
