Definitions

  • the invention relates to a telescopic boom in model construction, in which at least Three tubes are provided in series, in one direction of the series to a free end of the boom towards the outside in cross-section from tube to tube and getting smaller telescopically pushed into each other in pairs, guided against each other in a fitting manner are displaceable, in which the pipes can be pushed together and pulled apart with each of the three tubes facing the free end of the boom Pipe end forms an abutment breakthrough in the pipes pulled apart a bolt protrudes, which acts on the inserted tube by a spring element is provided, in which the bolt projecting into the abutment opening on the Free end of the boom facing a front abutment edge of the abutment opening the facing bolt surface forms and in which the bolt face starting from the front face of the transom forms a bevel towards the a lower abutment edge, the bar lowers.
  • miniature model construction there are miniature model devices or machines, e.g. Miniature model cranes, equipped with a telescopic boom in model construction are.
  • the telescopic boom forms an inner one with the largest tube in the outer cross section or rear end, which is attached to the model device or to the model machine itself is or will and is / will be equipped with a device at the free end of the boom, which is assigned to the function of the model device.
  • the telescopic boom will completely pushed together by hand until protrusions, e.g. Flanges, the pipes against each other butt and pulled apart completely by hand until all latches function have arrived.
  • the bolt occurs in this abutment breakthrough and takes up by abutting its front abutment surface at the front abutment edge of the abutment opening with the outer tube.
  • An object of the invention is therefore a telescopic boom of the type mentioned Type to create where the pipes can be pushed together by engagement the bars are controllable.
  • the telescopic boom according to the invention has this task dissolving, characterized in that when tubes are pulled apart the bolt with the front bolt surface out of the abutment opening protrudes and the rear abutment edge turns a rear locking surface, and that when pushing two pipes together the larger outer pipe with one front pipe area pushed back the bolt of the abutment opening holds that the rear locking surface has moved away from the rear abutment edge.
  • the larger outer tube forms an inner tube edge at the tube end facing the free end of the boom, which when pushing the two pipes together on the bevel of the transom of the inner smaller pipe runs up. This describes the interaction of the pipes in order to push them back the outwardly outstanding bolt by means of the second larger one, outer tube.
  • the telescopic boom has more than three pipes, e.g. four or five pipes on.
  • the tubes usually have a non-circular cross-section, so that two tubes pushed into one another or inserted into one another cannot be rotated relative to one another are.
  • the latch is provided on a pin which is in a bore of a slider can be pushed against the force of a compression spring serving as a spring element, which is clamped between the bolt and the slider.
  • the telescopic boom according to the drawing is at one end by means of a holding device 1 attached to a miniature model device 2 and forms on that of the holding device opposite end of a free boom end, not shown.
  • a holding device 1 attached to a miniature model device 2 and forms on that of the holding device opposite end of a free boom end, not shown.
  • four tubes 3, 4, 5, 6 are shown, namely in an pulled apart Status.
  • the rear end of the first tube 3 is seated on the holding device 1 and the tubes each have a circumferential flange or ledge at the front end 7.
  • the second pipe 4 and the following pipes protrude in the pulled apart Condition in each case with a rear pipe area 8 in the previous pipe.
  • all of the ledges 7 lie Pipes close together.
  • each tube 4, 5, 6 has an abutment opening 9 at the front tube end a distance from the front end of the tube that is slightly less than the length of the rear Pipe area 8 is.
  • each tube 4, 5, 6 is at the rear Pipe area 8 provided with a bolt 10, which when pulled apart the pipes protrude into the abutment opening 9.
  • the latch 10 forms a front latch surface 11, which is perpendicular to the central axis of the Pipes runs, assigned to a front abutment edge 12 of the abutment opening 9 is and towers above this according to FIG. 3.
  • the bolt 10 forms a rear bolt surface 13, which is perpendicular to the central axis of the tubes, a rear abutment edge 14 of the abutment breakthrough is assigned and does not tower over it according to FIG.
  • the latch 10 has an end bevel 15 on the end face, which extends from the front Bolt surface 11 drops towards the center axis of the tubes.
  • the bolt 10 sits on a support piece 16 which is arranged in the associated tube 4 from which the bolt protrudes through a guide hole 17.
  • the support piece 16 engages behind the tube 4 with shoulders 18.
  • the support piece 16 sits on a pin 19 which in a slider 20 can be pushed in, namely against the compressive force of a spring element 21, which is clamped between the support piece 16 and the slider 20.
  • the Slider 20 protrudes into a receiving hole of the inner tube 4 and is against the outer Tube 3 supported. It forms the larger tube 3 at the front tube end inner tube edge 22.
