Definitions

  • the present invention relates to the field 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.
  • pole constructions which are adjustable in length.
  • the adjustability can be used on the one hand to ensure that the length of the pole can be adjusted to suit the needs, and on the other hand also to reduce the pole to as small a pack size as possible, i.e. to make the length so much smaller that the Stick can be stored in a backpack or similar, for example.
  • Such constructions in which so-called inner tubes with a small diameter are displaceably mounted in an outer tube with a slightly larger diameter, and in which the relative position of the tube sections can be fixed by a locking mechanism, are known, for example, from DE 297 06 849 or also from the DE 497 08 829 or the EP 1 450 906 .
  • folding sticks for example known from WO 2012/104424 , in which individual stick segments are connected via plug connections.
  • the stick segments can then have essentially the same diameter, and the stick segments are connected to one another via a pull rope, so that after the individual stick segments have been plugged together, the segments are rigidly connected to one another by placing this pull rope under tension.
  • the problem with these constructions is that the flexible pull rope has to connect the individual pole segments and run through them. This means that such constructions are not very easy to manufacture and service and are difficult to put together according to different customer requirements.
  • the present invention relates to a folding stick with at least three or with at least four, or preferably five tube sections, the tube sections in the assembled state of the folding stick being rigidly connected to one another via plug-in connections along the stick axis, and at least two or at least three tube sections in the folded state only are still connected to one another via a movable connecting element, and wherein a stick handle is arranged on an uppermost pipe section and a stick tip is arranged on a lowermost pipe section.
  • At least one of the plug connections is implemented via an external clamping mechanism and/or a positive locking device.
  • connection as an external clamping mechanism, for example with a lever, and another as a positive locking device (arranged outside or inside), preferably the external clamping mechanism is then provided closer to the handle or on the pipe section on which the stick handle is arranged, and The connection with the positive locking device follows downwards.
  • the clamping mechanism is attached to a first pipe section, and in this a second pipe section, which has a smaller or almost the same outer diameter as the inner diameter of the first pipe section, and which is displaceably mounted in the first pipe section, can pass through in the relative axial position be fixed using the external clamping mechanism.
  • the alternative or additional form-fitting locking device is implemented on a second pipe section, the second pipe section having a smaller or almost the same outside diameter as the inside diameter of a first pipe section, and can be inserted into the first pipe section, and in the relative axial position by the form-fitting Locking device can be fixed.
  • the further plug-in connections are designed as pure plug-in connections, in which pipe sections, when plugged together, are only fixed in one axial direction, as long as they are not held together by the pull cable.
  • the pipe sections are connected to one another via at least one pull cable, which is attached to the lowest pipe section and to the top pipe section, and is arranged to run through the interior of the at least two or three middle pipe sections.
  • the folding stick is designed in such a way that it can be brought or transferred from the folded state into the assembled state by plugging the (further) plug-in connections together or sliding into one another via the continuous tensioning of the pull cable, and then by releasing the external clamping mechanism or at With the locking device released, the second pipe section is pulled out of the first pipe section until the pull cable is under tension, and by fixing the external clamping mechanism or the positive locking device.
  • the other plug connections are then fixed in both axial directions.
  • the locking device can preferably be constructed as follows: as a clamping device for the form-fitting, releasable axial fixing of an inner tube section which can be inserted into an opening of the clamping device attached to an outer tube, the clamping device having a circumferential plastic sleeve, on the outside of which a clamping lever via an axis which is perpendicular to the pole axis is arranged, tiltable against the restoring force of a spring element, wherein the plastic sleeve has two projections with through openings and/or recesses for the axle, and the clamping lever is mounted between these projections so that it can be tilted about the axle, and wherein the plastic sleeve has a radial through opening, the clamping lever having a first lever arm with a pressure area accessible from the outside Loosening the clamping device and a second lever arm arranged on the other side of the axis, the second lever arm having a clamping projection arranged essentially radially to the pole

  • cone end pin with an axial passage opening for the pull cable for each plug connection.
  • the cone end pin is releasably fastened in the pin area, for example screwed in or snapped into place, and each or at least one of these cone end pins has an axial slot through which the pull cable can be inserted into the through opening in the radial direction.
  • the axial slot for the introduction of the pull cable into the through opening in the radial direction is exposed or can be exposed or opened when the cone end pin is removed from the pin area.
  • the axial slot of the cone end pin can be designed in different ways.
  • the cone end pin is formed in one piece.

  • Such a cone end pin can be removed from the pin area (for example by unscrewing) and can then be opened over the film hinge, so to speak, so that the axial slot is available. However, it does not have to be opened completely; it is sufficient that the two halves on the side of the axial slot are expanded slightly in order to open it for the insertion of the pull rope.
  • the film hinge is preferably provided on an axial end face of the cone end pin. When the cone end pin is assembled/screwed in, the axial slot occupies a parallel distance of 0 or even smaller in some areas of the thread. This allows, for example, a non-positive tension to be transferred to the last thread turns and thus prevents the end pin from being unscrewed unintentionally.
  • the contact surfaces are usually parallel to each other (i.e. even an open slot when installed, but can be opened when removed). If the contact surfaces are slightly conical to one another, a securing effect can also be achieved by slightly increasing the outside diameter (because the surfaces lie parallel to one another during assembly). Of course, this can also happen if the surfaces remain parallel to one another and the external thread of the end pin is enlarged (in some areas).
  • releasable means that the cone can be removed non-destructively, if necessary with the help of a tool and reversibly, without loosening a solid bond (apart from, for example, a releasable screw locking varnish or similar) such as gluing.

  • the lateral slot of the cone end pin can be designed in such a way that the pull cable can be snapped into or out of the through opening of the cone end pin with slight resistance, or, as described above, it can also be implemented via a film hinge, which connects two cone end pin halves that are virtually separated in the axial direction on only one side of the through opening.
