Bergstock / Alpinstab

Abstract

This trekking pole is characterized by its exceptional telescopic length of up to 220 cm, depending on the user's height. Only this length provides optimal knee relief through the significant support it offers when descending. The short setting of approximately 135 cm and the medium setting of approximately 175 cm ensure comfortable and energy-saving handling when ascending.

Description

[0001] The invention relates to a one-handed, telescopically extendable trekking pole or alpine pole, which, due to its length, offers maximum knee relief when descending. It consists of two precisely fitting, sliding plastic tubes of different circumferences. This telescopic mechanism allows for easy extension or shortening of the trekking pole in three stages, from approximately 135 cm to a maximum of 220 cm. A spring with a nipple mounted in the inner tube locks and secures the poles at the three different lengths. The nipple engages in precisely aligned holes in the outer tube, thus fixing the tubes against each other. The desired pole length can be set by pressing and releasing the nipple, which then engages in one of the three holes. Metal sleeves, also with precisely aligned holes, enclose the tube at the three hole positions.A similar metal sleeve is also located at the single bore on the inner tube. These metal sleeves prevent deformation of the bores in the tube material during frequent use, ensuring the nipple always engages correctly. When extended to its maximum length, the trekking pole provides the necessary overall length, thus ensuring optimal joint relief for the knees when descending by providing maximum support. State of the art:

[0002] The underlying problem behind the invention is knee pain experienced by mountaineers when descending – a reason why this beloved sport can often no longer be practiced, or only to a limited extent. Conventional hiking and trekking poles offer only limited relief from the frequently occurring knee pain during descent.

[0003] Solution and advantages of the invention: The maximum pole length of approximately 220 cm, significantly greater than the user's height, combined with leaning the body forward and using both hands / arms when descending, results in maximum relief for the knee joints. The mountaineer can descend to the valley with virtually no strain on the knees. Quick and easy handling is ensured by the three-stage extension / shortening mechanism on a telescopic base, securely locked in place by a metal spring with a nipple mounted inside the tube. The desired length can be adjusted with a single movement. The mountaineer does not need to pack or remove individual parts from their backpack. Another advantage is that endurance is increased when climbing, as the use of arm traction distributes the effort more evenly between the arms and legs than is possible with conventional trekking poles. Further advantages include the fact that other joints, such as...Hips and spine benefit from the relief, and joint surgery can even be postponed. It is also helpful for deterring animals, e.g., cows in alpine pastures. The staff / stick can be used by anyone 150cm tall or taller.

Claims

[1] Mountain range characterized by Its unique feature is that it can be extended to an exceptional length of 220 cm, depending on the user's height. Only this length provides the best possible knee relief through the enormous support effect when descending. The short setting of approximately 135 cm and the medium setting of approximately 175 cm ensure comfortable and energy-saving maneuverability when ascending. [2] Mountain range characterized by that it consists of a 2-part hollow tube set made of high-strength plastic, with the respective inner tube fitting exactly into the respective outer tube. [3] Mountain range characterized by that the outer tube is provided with holes at different positions along its length. [4] Mountain range characterized by , in that the inner tube also has a hole. In the cavity of this inner tube is a metal spring with a nipple that protrudes through this hole. [5] Mountain range characterized byThis nipple, when pressed with your thumb, locks the inner tube into the outer tube at the desired drilling position. This locking mechanism ultimately results in the desired pole length for the current application: "Short / 135cm," "Medium / 175cm," or "Long / 200cm to max. 220cm." [6] Mountain range characterized by The inner tube has a milled recess approximately 30mm wide at the hole location. The outer tube has three such recesses at corresponding intervals. The metal collars glued into this recess enclose both the inner and outer tubes. These collars also have a hole and protrude slightly into the hole, allowing the locking nipple to protrude through. The metal collars processed in this way prevent deformation of the hole in both the inner and outer tube material with frequent use of the alpenstock. [7] Mountain range characterized by that despite its length it weighs about 980 grams. [8] Mountain range characterized by that the lower end of the inner tube is provided with a tip made of high-strength metal to provide the necessary grip on the ground and a small plastic plate to prevent sinking into soft ground. [9] Mountain range characterized by that the upper end of the outer tube is equipped with a handle.
