Pole for sporting activities like skiing, trekking and the like

Abstract

The invention is a pole for sporting activities of the type comprising a tubular body provided at one end with a tip and at the opposite end with a handgrip, wherein the tubular body comprises a tubular element developing mainly in longitudinal direction and having a closed profile in cross section, and at least one shaped element developing mainly in longitudinal direction fitted inside the tubular element and having an open profile in cross section. Between the outer surface of the shaped element and the inner surface of the tubular element opposing each other there is a filling structure.

Description

BACKGROUND OF THE INVENTION [0001] The invention concerns a pole for sporting activities, particularly suited to be used for activities like skiing, trekking and the like. [0002] It is known that the poles that are used in the sporting activities mentioned above substantially comprise a tubular body that develops longitudinally and is provided at one end with a tip that is pushed against the ground and at the opposite end with a handgrip that is held by the user. [0003] The tubular body of the pole is generally made of aluminium or an aluminium alloy, but the most modern versions use also highly technological materials, like for example carbon. [0004] However, it is indispensable for the tubular body of the pole to be light and above all resistant, due to the fact that during use it is subjected to particularly heavy stress. [0005] For this reason poles have been designed, whose tubular body is made of a composite material, like for example the pole described in patent DE 20220186U....

AI Technical Summary

Benefits of technology

[0024] Advantageously, the pole that is the subject of the invention makes it possible to simplify the construction technique of poles with composite structure and furthermore, still advantageously, to produce composite poles that though ensuring the same resistance weigh less than composite poles of known type.

Problems solved by technology

A first drawback is constituted by the fact that said pole is difficult to construct, since it is necessary to process with great precision at least two of the tubular elements that are coaxially coupled to each other in order to obtain the desired mutual connection.

Another drawback lies in that the tubular body of the pole offers uniform resistance on its entire cross section and therefore it is not possible to reinforce it only in some areas that are more subjected to stress, thus limiting also any excess weight.

Another drawback is represented by the fact that in order to make the tubular body of the pole it is necessary to prepare a production line capable of carrying out special additional processings compared to those included in the standard production cycle.
