  • Patent number: 5941435
    Abstract: A single, telescoping, collapsible, quick-release snowboarding pole with leg mounting system includes a telescoping, collapsible pole and leg mounting assemblies, to secure the pole, in the collapsed position, to the lower leg of an individual, such as a snowboarder. This invention allows the user to quickly release the collapsed pole from the leg mounting assemblies and extend and lock the telescoping pole, to use as needed, usually to gain momentum while snowboarding or performing other outdoor sports. The pole comprises three sections of telescoping tubing, the lower pole section sliding into the middle pole section which then slides into the upper pole section, in the collapsed position. The pole is locked into its extended position by way of two snap-lock buttons positioned inside the middle and lower pole sections, respectively.
