发明名称 Yieldable post and method of using same
摘要 A safety pole useful as a ski gate is constructed of a core of flexible, self redressing material, covered by a flexible protective mesh sleeve and capped at both ends. The core is soft and flexible enough to prevent injury to skiers, yet self redresses to its original, normally vertical position quickly and reliably. The mesh sleeve is tough and flexible, to bend with the core while protecting it from damage from skis. The end caps protect the core from damage upon insertion in the snow. By making some or all of the elements of fluorescent, brightly colored or light reflective material, or by adding reflective tape or stickers to those elements, visibility of the pole is enhanced. The pole is suitable for retaining ropes or ribbons to demarcate lift line paths, boundaries and the like.
