Definitions

  • the present invention relates to a length-adjustable tube, especially for ski or Walking sticks according to the preamble of claim 1.
  • the expansion device has an expansion element provided with a conical internal threaded bore, into which an expansion screw provided with a conical external thread rotatably engages.
  • the object of the present invention is therefore a length-adjustable tube, especially for ski or To create walking sticks of the type mentioned at which the spreader in a satisfactory manner and with sufficiently high forces can be spread.
  • the measures according to the invention are large and ensures uniform cylindrical expansion. Because of the between the adjusting screw and the expansion element interposed inner element can be considerably larger Forces are transmitted because of the sliding movement of the Inner element within the expansion element, the former made of a much harder material, for example Metal than the expansion element, which can be because of its Spreading and friction effect against the inner circumference of the Outer tube should be made of a plastic.
  • length-adjustable tube 10 is an inner tube 11 in one Outer tube 12 guided telescopically. This is the Inner tube 11 at its end 13 facing the outer tube 12 provided with a spreading device 15, by means of which the inner tube 11 in the outer tube 12 at any position can be fixed by clamping.
  • the spreading device 15 has an outer element in the form a spreading element 16, an inner element 17 and a Adjusting screw or external threaded rod 18.
  • the in axial External threaded rod 18 arranged in the direction of the tube 10 is in a manner not shown with one end portion rotatably held at the end 13 of the inner tube 11. This can for example in such a way that the External threaded rod 18 inserted into an end plug 15 or is in one piece with it and together with this by means of a cross bolt on the inner tube 11 or through each gluing is held in rotation.
  • On the External threaded rod 18 is the inner element 17 with its axial central internal thread 21 screwed.
  • the Inner element 17 is provided on the outside with a cone 22 or conical.
  • the inner element 17 is so far screwed onto the threaded rod 18 that in not spread hibernation a certain room or Distance 23 between a narrow forehead 24 and the end 13 of the inner tube 11 is present.
  • the external threaded rod 18 penetrates the internally threaded bore 21 of the inner element 17 and is at its protruding end with a stop part 26, such as a lock nut rotatably connected.
  • the stop part 26 overlaps the wider one Forehead 25 of the inner element 17 partially.
  • the outside expansion element 16 has an inner cone or inner cone 27, the slope of that of the outer cone or - cone 22 of the inner member 17 corresponds. According to the Figures 1 and 3 is the inner element 17 in the counter-directed expansion element 16 added without play, with outer cone 22 in the illustrated embodiment and inner cone 27 are of equal length. At the The spreading element 16 is an exemplary embodiment made of a plastic, while the inner element 17 Are metal.
  • the expansion element 16 the outer peripheral side in Is essentially cylindrical, has one Inner tube 11 facing away, with a crowned Outer peripheral surface 29 provided annular insertion or Receiving part 28.
  • the expansion element 16 is both from its front end facing the outer tube 12 as well from its rear end facing the inner tube 11 provided a slot arrangement, each of two diametrically opposite slots 31 and 32 or 33 and 34.
  • the pair of slots 31, 32 offset circumferentially relative to the pair of slots 33, 34. This results in the embodiment even offset.
  • a longitudinal center Transition area 36 are the two pairs of slots 31, 32 and 33, 34 provided overlapping. It goes without saying that everyone Slot arrangement also more than two on the circumference can have distributed slots.
  • each elastic plastic ring 37 or 38 surround which rings 37, 38 in an annular groove on the outer circumference of the Spreading element 16 are sprayed or mounted.
  • the expansion element 16 from a relatively hard and is made of smooth plastic on the outer circumference
  • the elastic rings 37 and 38 from a relative soft and rougher or non-slip on the outer circumference Injection molded plastic.
  • the outer circumference of the elastic rings 37, 38 projects beyond the cylindrical outer peripheral part of the Spreading element 16 by, for example, about 1-2 mm however approximately equal to the maximum outer circumference of the spherical peripheral surface 29 of the insertion part 28. Die
  • the outer surface of the rings 37, 38 can be shown in FIG Be crowned.
  • one Spreading device 15 ' are the relatively flat cone 22 and inner cone 27 of the spreading device 15 according to FIG. 1 or 3 designed or subdivided in the manner, that there are several cones 22 'or inner cones 27 'result. With the same length of inner element 17 'and Spreading element 16 'result in steeper cones which Self-locking between inner element 17 'and expansion element Reduce 16 '.
  • the spreading device 15 ' also has a Entry ring part 28 and is with its inner element 17 ' brought on a threaded rod 18.
  • the expansion element 16 ' has in this embodiment in which a Subdivision into three cones 22 'and 27' is provided, three arranged one above the other in the axial direction elastic rings 37 'to 39'.
  • the spreading device 115 has two inner elements 117 and 117 ', which are arranged axially one behind the other, that their outer cones 122 and 122 'against each other directed, i.e. with their smaller end are arranged opposite each other.
  • the one Inner element 117 is on a threaded rod 118 for example right-hand thread and the other inner element 117 'on a threaded rod 118' with, for example Left thread threaded.
  • the two threaded rods 118 and 118 ' are connected to one another in a rotationally fixed manner.
  • the expansion element 116 the spreading device 115 is in one piece and on it the Inner element 117 receiving end with a first Inner cone 127 and on its inner element 117 ' receiving end with a second inner cone 127 ' Mistake.
  • the spreading element 116 according to FIG. 5 has the expansion element 16 according to Figure 2 two accordingly trained partially axially one behind the other arranged elastic rings 137 and 138.
  • Figures 6 to 8 show variants of the elastic rings 37, 38 or 37 'to 39' or 137, 138 of the above Embodiments that also serve here, the Spreading element 16 and 116 in the unexpanded state Initial friction against the outer tube 12 regardless of the diameter tolerances between the inner tube and outer tube to enable or guarantee.
  • an inner element 217 is surrounded Spreading element 216 at least one slotted on one side Ring 237 applied and in an annular groove of the expansion element 216 placed.
  • the slotted ring 237 has two layers formed, the inner in the annular groove of the Spreading element 216 lying layer 242 from a realitv hard plastic, while the outer layer 243 made of a soft elastic, with a non-slip surface provided plastic and the outer peripheral surface of the spreading element 216 protrudes. It is advisable the outer surface of the outer layer 243 of the slotted To form ring 237 crowned in the axial direction. Of the slotted ring 337 can thus easily pass through elastic expansion mounted over the expansion element 216 will.
  • Figures 7 and 8 show soft elastic elements 337 and 338, which are immediately in formations 346 and 347 of the Spreading element 316 are introduced or injected.
  • the soft-elastic elements 337 and 338 which according to FIG elongated rectangular and point or are blotchy, stand over the outer peripheral surface of the Spreading element 316 and 316 'in front and are in the axial Seen crowned in the direction.
  • the one used soft elastic plastic has a corresponding non-slip surface.
