Abstract

Abstract Adjustable slalom pole, consisting of a standpipe, a ground part to be inserted into the ground and a tipping element arranged between ground part and standpipe. The standpipe consists of fiber-reinforced synthetic material. This wall strength of the standpipe consists of fiber-reinforced synthetic material. The wall strength of the standpipe tapers off from bottom to top preferably step-wise.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 122 words
A self-redressing, slalom pole comprising a standpipe, a ground part to be inserted into the ground and a tipping element arranged between the ground part and the standpipe, said standpipe comprising fiber-reinforced synthetic material and having a wall thickness that tapers off in steps from bottom to top, said fiber-reinforced synthetic material being applied in several layers including outer and inner layers, said fiber-reinforced synthetic material including, in at least said outer layer, a synthetic resin fiber construction embedded in a matrix of synthetic resin, said fiber-reinforced synthetic material including threads with an orientation substantially in a longitudinal direction of said standpipe and including, in at least a lower partial area of said standpipe, further threads oriented transverse to the pipe axis.
Claim 2
Dependent Claim 122 words
A self-redressing, slalom pole comprising a standpipe, a ground part to be inserted into the ground and a tipping element arranged between the ground part and the standpipe, said standpipe comprising fiber-reinforced synthetic material and having a wall thickness that tapers off in steps from bottom to top, said fiber-reinforced synthetic material being applied in several layers including outer and inner layers, said fiber-reinforced synthetic material including, in at least said outer layer, a synthetic resin fiber construction embedded in a matrix of synthetic resin, said fiber-reinforced synthetic material including threads with an orientation substantially in a longitudinal direction of said standpipe and including, in at least a lower partial area of said standpipe, further threads oriented transverse to the pipe axis.
Claim 3
Dependent Claim 30 words

Claim 6
Dependent Claim 32 words
The self-redressing slalom pole according to claim 1 further comprising roving skeins, preferrably made of carbon fibers, additionally descretely distributed in the fiber reinforced synthetic material over the circumference of said standpipe.
Claim 7
Dependent Claim 17 words
The self-redressing slalom pole according to claim 1 wherein said standpipe is filled with a foam material.
Claim 8
Dependent Claim 16 words
