- The present invention relates to a hiking stick, which enables the lengths of multi-stage support pipes to be quickly and simply adjusted by a simple touch and elastically supports the weight of a user when walking with the stick.
- A hiking stick is generally configured to decrease the consumption of physical strength in such a way to absorb about 30% of the total weight applied to user's legs, while providing a stable hiking by maintaining balanced hiking postures when the user climbs up or down mountain. When the user climbs down mountains, the hiking stick may effectively absorb the impacts applied to the user's knees, so such a hiking stick is widely used by men and women of all ages because it is regarded as one of the key hiking equipment.
- The above-described hiking stick is configured in such a way that the length thereof may be adjusted for easier carrying. More specifically, the lengths of the multistage support pipes may be elastically adjusted by tightening or loosening the multistage support pipes in such a way to rotate a nut type tightening member.
- Since the related length adjustable hiking stick is configured to elastically adjust the length by tightening or loosening the multistage support pipes in such a way to rotate a thread-engaged tightening member, it takes relatively longer time to strongly tighten or loosen the tightening member while causing complicated work. If the tightening member is not tightly engaged, the hiking stick may not withstand strong impacts when touching on the ground, so the support pipes may unintentionally slide into the other support pipes, thus breaking the parts.
- The hiking stick is generally made from a predetermined material and is configured to have high durability, which are strong and high enough to prevent the hiking stick from bending or breaking when a user touches on the ground. When the force of about 41 kg is applied for 15 seconds to a portion about 10 mm away from the center of the hiking stick, it should not be bent or broken or deformed; however many of the related hiking sticks fail to pass the resistance test based on the materials of the hiking sticks.
- Due to the above-described problems, if the support pipes slide into the other support pipes or the hiking stick is bent or deformed, the user may lose the center of gravity when climbing down mountains, which results in critical accidents.
