Definitions

  • the present invention relates to a tube sleeve for a multi-segment stick, in particular for a telescopic stick or folding stick. Furthermore, the present invention relates to a sports pole having such a tubular sleeve, e.g. in the area of poles for hiking, Nordic walking, but also in the broadest sense for other sports such as cross-country skiing or alpine skiing, alpinism, etc.
  • Such telescopic constructions in which so-called inner tubes are mounted with a small diameter slidably in an outer tube with a slightly larger diameter, and in which the relative position of the pipe sections can be determined by a locking mechanism, for example, from the DE 297 06 849 or even from the DE 497 08 829 or the EP 1 450 906 ,
  • a locking mechanism for example, from the DE 297 06 849 or even from the DE 497 08 829 or the EP 1 450 906
  • the stick in particular in the lower region, where typically the thinnest tube is arranged has a very small wall thickness, and thus for some applications no longer shows sufficient rigidity.
  • the structures disclosed in these documents are not always optimally suited for all applications and users, since the relative position of the individual bar pipe sections must be ensured by a rotation of these bar pipe sections relative to each other, including corresponding manually applied rotational forces required are.
  • An improved folding stick is from the WO 2012/104424 known. With regard to the preferred embodiment of the folding stick per se is the disclosure of this WO 2012/104424 directed.
  • an object of the present invention to provide a structurally simple and therefore robust folding stick which can be folded together as small as possible, for example in order to be stored in a backpack or a bag, but at the same time the disadvantages of the prior art the art known folding sticks to be eliminated.
  • the harmful game and the associated possibly occurring rattling noise resulting from a mutual contact can result from inner tube section and outer tube section can be avoided.
  • This object is achieved by a stick with the features of claim 1.
  • the present invention also leads to increased stability, longevity and robustness of the stick.
  • the present invention relates to a stick with at least two, preferably at least three or four pipe sections.
  • the pipe sections are connected together in the assembled state of the stick via at least one connector along a rod longitudinal axis A, and at a top pipe section a stick handle is usually arranged and at a lowermost pipe section a stick tip.
  • At least one of the plug-in connections is designed as a form-fitting and / or non-positive latching device between a first pipe section and a second pipe section.
  • the latching device may be positive-locking mechanisms with so-called push-buttons, ie with spring-loaded radial latching pins which are mounted in the inner tube and engage in recesses or holes of the outer tube or a tube sleeve attached thereto or come into abutment with stop edges of these elements.
  • positive locking mechanisms in which the inner tube has a stationary stop ring, paragraph or rib, as is known for simple connections.
  • non-positive internal clamping as in particular from the EP 1 450 906 known. Also possible are combinations of these mechanisms.
  • the second pipe section has a smaller or almost the same outer diameter as the inner diameter of the first pipe section, and thus can be inserted into the first pipe section (7).
  • the pipe sections can now be fixed according to the invention in their relative axial position by the latching device, wherein the connector comprises a rigidly fixed to the first pipe section pipe sleeve which projects beyond the end of the second pipe section facing the first pipe section in a projecting region, this end edge radially a circumferential, directed towards the second pipe section flange engages and surrounds the second pipe section in the projection region.
  • the construction according to the invention is now characterized in particular in that a typically elastic clamping element is arranged in the projection region between a radial inner surface of the tube sleeve and the radial outer surface of the second tube section.
  • the tubular sleeve with its flange engages directly around the lower edge of the first pipe section so that the inside of the flange comes into abutment with the lower edge of the pipe section, and the flange protects with its axial bottom then the end edge of the first pipe section for the positive fastening ,
  • the corresponding fixing pin does not come into contact with the lower edge of the first pipe section and can not damage and injure accordingly.
  • the clamping element is arranged in this receiving groove.

  • This flange which advantageously adjoins a hollow cylindrical portion of the pipe sleeve, engages around the lower end of the first pipe section, or the lower end of the first pipe section rests on a shoulder of the flange.
  • the flange can also be achieved by a conical taper of the tubular sleeve directed downwards towards the tip of the pole.
  • the clamping element is arranged in the radial direction between the second pipe section, or the radial outer side of the second pipe section and a radial inner side of the pipe sleeve.
