Abstract
The invention is directed to a Nordic walking/running/exercise pole, which is equipped with a handle flexing towards the pole shaft.
Claims5
A Nordic walking/running/exercise pole, comprising a flexible handle that is at a certain angle to a pole shaft, and wherein a handgrip of the said handle forms a backwards-downwards opening, circa 45- to circa 65-degree angle to the pole shaft that has a straight profile and is in an upright position to the walking direction, which angle's higher degree represent the handle's resting phase and the lower the most tensioned phase, which part of the handle held by a user's hand forms a backwards and upwards-opening, circa 70-90 degree angle to the vertical line when the pole is in the position where the user's hands are hanging with straight arms along the sides of the user's body with the handle in the hands and the pole straightened backwards with the tip leaning against a surface, the pole having its characteristic length from the user's toes up to below the lowest costal arch, in which way the handle at the aforementioned angle functions as an lever with a flexing resistance, circa 20-80 kg, generating a pushing force both downwards and backwards in the pole shaft, and, when walking on a hard surface, the flexible handle also functions as a shock absorber for the pole spike and both the handle's angle to the pole shaft and the pole's length provide a pushing direction, allowing the pole tip a surface grip;
- wherein the handle's flexible bending takes place either in the handle's own integrated part or in a separate flexible part joining the handle and the pole shaft, where the fastening of the handle onto the pole can be realised at the pole shaft's end or side, at a traditional handle's top, or at a traditional handle's base, and the hand-held part of the handle has the form of straight handle and a widening at the back end that prevents the handle from slipping out of the user's hand and operates as a flexing stopper against the pole shaft, which pole shaft's tip is equipped with at least one steel spike.
