Title: Multi Funtional stick for climbing
Inventor: KIM JUN WOONG
IPC: A45B9/00
Filed: 2020-07-06
Abstract: The present invention relates to a multifunctional climbing stick. The present invention rapidly and conveniently adjusts a length of multi-stages supporting pipes; elastically supports a weight when a user touches the stick by applying elasticity to a spike of a lower end of the stick; and allows the user to stably use the stick. The present invention increases portability by minimizing a length of the stick when not in use. Since an inclined hole is drilled in a handle of the stick to insert a conventional upper supporting pole, when the stick is installed in a tent, the stick is used as a lower supporting pole. As the number of tent installation members decreases, a climbing bag for storing the tent installation members becomes lighter to make it easy to climb. Therefore, the user allows fun and healthy leisure activities. Even though the length of the stick is extended as much as possible, the stick is stably used without inserting or discharging the multi-stages supporting pipes.
