ABSTRACT:
A gate pole for ski sport comprises a rigid ground tube (2) and a stand tube (3) extending upwardly from the ground tube (2), this stand tube being fashioned as a tubular, pressurizable, pole-shaped hollow member (12). The lower end (19) of the tubular hollow member (12) consisting of an elastic sheet material, at which end a valve (25) is provided, is accommodated in a rigid sleeve (6) connected with the ground tube (2). The tubular hollow member (12) is surrounded on the outside by a braided hose (10) which is closed (11) at the upper end of the tubular hollow member (12). The tubular hollow member (12) is in contact with the braided hose (10) only if it has been placed under a pressure of 4-8 atmospheres gauge. The gate pole, as contrasted to other air-filled gate poles, has a defined tilting zone without the tilting characteristic being adversely affected.
