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.
