Description

Climbing Cane Buffers {The buffer for an alpenstock}

The present invention relates to a cane shock absorber for mountaineering, which will be described in more detail. The climbing cane shock absorber developed to be able to effectively absorb a shock with a more durable and simple structure for carrying a secondary use when climbing It is about.

In general, the climbing cane is a form of a handle formed on the top of the stick, although there is no big difference in the structure of the cane and the various forms commonly used by the elderly.

In recent years, for convenience of storage, sticks are inserted into pipes having different diameters, and folded and stored according to necessity, and types that can be freely adjusted to fit the height have been widely used.

However, if you use the walking stick for a long time when climbing, the impact that occurs when the stick collides with the ground and the weight supporting force on the handle are continuously applied to the wrists and shoulders, which causes the wrists to squeak or cough. Physical changes, such as getting tired, make you feel tired easily.

Of course, correcting the posture can greatly reduce this problem, but if you are not a professional mountaineer for climbing as a hobby, the climbing cane is a burden to the body rather occurs.
