Definitions
- the present invention relates to a length-adjustable pole, in particular for Nordic walking, roller skating or the like, according to the preamble of claim 1.
- the adjustment range is> 300 mm, which means that due to the weight and the center of gravity lying near the center of gravity, the swing properties are adversely affected, which is not necessarily on trekking poles plays a role, but brings with them for Nordic walking or roller skating problems.
- Object of the present invention is therefore to provide a length-adjustable floor of the type mentioned, in which despite variable length pole the swing characteristics are not adversely affected.
- the center of gravity is displaced upwards in the direction of the handle in such a length-adjustable pole, since the adjustment mechanism is closer to the pole grip and weight is saved due to the lower overlapping material. All this has a positive effect on the swing weight and thus on the swing behavior.
- This selected maximum adjustment is sufficient in such applications completely, since it Unlike trekking poles (short packing length), this is about adapting the length to different conditions of use.
- Preferably used tubes or pipe combinations result from the features of claim 6. These may be made of aluminum and / or carbon fibers.
- Figure 1 shows a schematic side view of a length-adjustable floor in the form of a Nordic walking stick
- FIG. 2 shows a longitudinal section of the stick according to FIG. 1 in the area of the adjusting mechanism.
- the length-adjustable floor 10 shown in the drawing has an inner tube 11 which is provided with a tip 13 in his free end and is provided with a rubber buffer 14 and / or with a plate, and an outer tube 12, in which the inner tube 11 is telescopically inserted and which outer tube 12 at its end facing away from the inner tube 11 with a pole grip 16, via the outer tube 12th is pushed, is provided.
- the pole grip 16 has a hand strap 17 for a user to hold the adjustable-length pole 10.
- Such a length-adjustable floor 10 is used for example in Nordic walking, roller skating or the like.
- the telescoping telescoping inner tube 11 and outer tube 12 is configured such that the inner tube 11 over a maximum displacement of 250 mm and preferably in the range of 100 mm to 200 mm and more preferably in the range of 100 mm to 150 mm within move the outer tube 12 and set steplessly.
- the center of gravity of the length-adjustable stick 10 is moved as far as possible in the direction of the handle, which means that the outer tube 12 has a maximum length of the size of the maximum adjustment plus a safety length.
- the safety length is given by the fact that the inner tube 11 can still be set safely and without play in the outer tube 12 at maximum retracted adjustment.
- this safety length is in the range of 50 mm to 100 mm.
- a part of the outer peripheral side is covered by the pole grip 16.
- a small extension or of the pole 10 over the length of the outer tube 12 is produced by the pole head connected to the hand strap 17.
- the outer tube 12 is likewise due to the specified small maximum adjustment travel very short, so that overlapping pipe material and thus weight is saved and to be described below, preferred adjustment or fixing mechanism 20 is mainly laid in the direction of the stick handle 16 and in the vicinity.
- a rotatable with the inner tube 11 expansion cone 27 which moves axially relative to the Spreizelementabroughen 26 upon rotation of the inner tube 11 due to its external thread and presses them in the radial direction against the inner wall 24 of the outer tube 12.
- large radial expansion forces by the expansion element 23 against the inner wall of the outer tube 12 are necessary.
- the smaller diameter inner tube 11 is fixed in the pole grip 16, wherein the pole grip 16 covers part of the length of the inner tube 11, as described for Figure 1 for the outer tube 12.
- the inner tube 11 is very short, ie corresponding to the maximum displacement plus extending in the pole grip 16 length range plus the aforementioned safety length range of 50 mm to 100 mm.
- the outer tube 12, which in this case is slidable over the inner tube 11, is thus the longer tube part, which at the lower end with the pole tip 13 and / or the rubber buffer 14 and / or a plate is provided.
- Between the inner tube 11 and Aulienrohr 12 is one of the described adjustment / Festlegmechaniken 20 is provided.
- This variant results in a rigid design in the stock handle remote area.
- the continuous adjustment / fixing mechanism 20 may also be formed by a provided with an inner cone and axially movable within narrow limits clamping sleeve and a movable within this along a thread expanding cone or cone according to DE 202 07 554 Ul.
- the adjusting / fixing mechanism 20 may be formed instead of a continuously lockable spreader by a gradually snap-button connection in which a resilient detent button on the inner tube in one of several holes in the outer tube is latched.
- the outer / inner pipe pairings can have different dimensions. 16 mm / 14 mm is preferred when the outer tube 12 is fixed in the pole grip 16, and 12 mm / 16 mm or 14 mm / 16 mm when the inner tube 11 is fixed in the pole grip 16.
- the outer tube 12 and / or inner tube 11 may be made, for example, of carbon fibers or carbon fibers or of a mixed fabric containing carbon fibers or carbon fibers. It is understood that instead of this material for the one and / or other tube part 11, 12, an aluminum tube can be used.
