Abstract: A pole section for temporary assembly with similar pole sections into an elongate pole assembly whereby a user can perform work on a remote worksite elevated by up to 20 m above the user. Each pole section includes a male end and a female end, having a complementary taper to slide into or around the other of a male or female end and form a fluid tight joint with a stiffness similar to or greater than the overall stiffness of the pole. The ends of each pole section include one of first and second complementary coupling parts. The coupling parts cooperate to prevent the pole sections moving relatively towards each other under the weight of overlying pole sections in use to prevent the pole sections jamming A resiliently deformable locking structure is provided in a coupling part by a ring spring.

Abstract: A pole section for temporary assembly with similar pole sections into an elongate pole assembly to extend the manual reach of a user whereby a user can perform work on a worksite remote from the user where the site is elevated by up to 20 m above the user. Each pole section (1a, 1b) includes a male end (2) and a female end (3), having a complementary taper to slide into or around the other of a male or female end and form a fluid tight joint with a stiffness similar to or greater than the overall stiffness of the pole. The ends (2, 3) of each pole section (1) includes one of first and second complementary coupling parts (6, 9). The coupling parts cooperate to prevent the pole sections moving relatively towards each other under the weight of overlying pole sections in use and therefore prevent the pole sections jamming together and becoming difficult to disassemble. A resiliently deformable locking structure is provided in a coupling part by a ring spring (114).
