Definitions

  • the invention relates to a device for guiding couplings on model railroad vehicles of any system according to the preamble of claim 1.
  • the invention is based on the object to design the coupling guide system of the type mentioned which allows a gap-free driving at straight running and cornering driving through a sliding past the buffer on adjacent Fahrzeu g end without becoming caught so that the necessary during curve driving through "drawbar extension" (Automatic pushing out of the coupling pin) is effected as soon as the tiller arm swings out of the longitudinal axis of the tiller - neutral center position.
  • this system should manage with a minimum number of individual parts and thus be inexpensive to manufacture, as well as allow maintenance-free operation and enable smooth operation even with small radii of curvature of the rails.
  • the clutch guide system according to the invention should be easily attachable to both new and older models from any manufacturer.
  • this object is achieved in a device according to the preamble of claim 1 by the features listed in the characterizing part of this claim.
  • the subject matter of the invention achieves improved guidance of the carriages compared to the prior art, and the assembly or attachment of the coupling, which consists of only a few individual parts and occupies an area of less than 6 cm 2 - Guide system much easier, especially since the latter only has a total height of about 2 mm.
  • the small number of individual parts also significantly reduces manufacturing, storage and assembly costs.
  • maintenance-free operation can be guaranteed through the use of wear-resistant and self-lubricating plastic parts.
  • the device for guiding couplings on model railroad vehicles essentially consists of a guide template 1 and a T-shaped drawbar 2, which is composed of the crosspiece 3 and the drawbar leg 4 extending in the direction of the longitudinal axis DL of the drawbar.
  • the tiller arm 4 can optionally be provided at its free front end or in the region of the crosspiece 3 with a pin 5, which for connecting and compensating for height differences with the receiving piece 6 shown in FIG. 3 for the coupling, not shown in the drawing, on the coupling to be coupled Trolley serves.
  • the receptacle 6 has a recess 7 corresponding to the shape of the peg 5 for receiving the peg 5, on which the receptacle 6 can be adjusted to the required height, possibly with spacers, and can be fastened, for example, by gluing.
  • the guide template 1 is shown in FIGS. 1 and 4 open at the bottom and can be closed by a cover plate 8 with the help of the pins 9 attached there by pushing into the recesses 10 made in the guide template 1.
  • the rear edge 11 of the crosspiece 3 of the T-shaped drawbar 2 lies without play on the rear edge 12 of the guide template the free end pieces 17, 18 of the cross piece 3 point at the corners 15, 16 of the guide template 1 formed by the curved or straight ends and the rear edge 12 of the guide template 1.
  • the end pieces 17, 18 of the tiller cross piece 3 lying in these corners 15, 16 when driving straight ahead either lie directly on the curved guide surfaces 23, 24 of the curved branches 13, 14 of the guide template 1 without play (FIGS. 5 and 9), or else they come to rest at the transition point 19, 20 of a straight part 21, 22 to the curved guide surfaces 23, 24 of the curved branches 13, 14 (FIG. 7).
  • the corner 16 serves as a fulcrum for the T-shaped drawbar 2 and the free end of the leg 4 with the pin 5 executes the path designated B in FIG. 2.
  • the tiller arm 4 with the pin 5 is pushed further out of the guide template 1. In this way the buffers of the coupled carriages can be guided past one another without getting caught.
  • cornering against the direction of arrow 25 ' the same process takes place in the opposite direction, see the path designated by A in FIG. 2.
  • springs 26 are attached to the crosspiece 3, which run practically parallel to the longitudinal axis of the drawbar DL and are attached approximately in the middle of the corresponding inclined surfaces 27 of the crosspiece 3. In some cases it may also be advantageous to the springs at an angle ⁇ of about 20 0 to 50 ° to attach to the pole longitudinal axis DL, as is illustrated in Fig. 6 by the springs 28 shown in solid lines. To increase the spring force, several parallel springs or a combination of parallel and oblique springs - as indicated in FIG. 6 - can also be provided.
  • the nose 30 attached to the rear edge 12 of the guide template 1 can either be arranged rigidly or else movably under the pressure of a spring 31 and thus snap into the recess 32 and exert pressure on the drawbar 2. This makes it easy to move speed increased.
  • the drawbar 2 has one or two recesses 7 'or 7 ", into which a corresponding pin 5 on the receiving piece 6 can optionally be introduced.
  • the recesses 7', 7" or the pin 5 can be However, in the sense of a kinematic inversion, they can also be interchanged. If the recess 7 ′ made in the crosspiece 3 of the drawbar 2 is used, the end of the drawbar that is not required can be broken off at a predetermined breaking point 33.
  • the lower cover plate 8 has a preferably triangular cutout 37 with rounded corners through which the coupling pin 5 engages with any tiller position.
  • the play-free mounting of the drawbar 2 according to FIG. 8 is achieved in that on the rear edge 12 of the guide template 1, provided with or without a nose 30, a straight section 21 or 22 at right angles on both sides Guide surface of the rear edge 12 is mounted upright, which merges into the curved branches 23, 24 of the guide template 1 at points 19, 20.
  • the end pieces 17, 18 of the cross piece 3 are shaped so that they rest in the normal position (straight ahead) on the rear edge 12 and the transition points 19, 20 to the curved branches 23, 24.
  • springs 26 or inclined springs 28 or combinations of the springs 26, 28 are provided in each case parallel to the drawbar elongation axis DL.
  • the recess 32 can in turn be semicircular and thus correspond to the shape of the nose 30.
  • the rear longitudinal side 11 of the drawbar crosspiece 3 with a V-shaped incision, the apex of which, in accordance with the radius of the nose 30, is preferably rounded, while the parts adjoining the apex end in straight lines 32a, 32b ( see dashed representation in Fig. 8).
  • the arrangement can also be such that the straight lines 32a, 32b form an obtuse angle of more than 120 °, preferably 150 °, without rounding.
  • the continuously curved branches 13, 14 are brought up to the rear edge 12 of the guide template 1, against which the rear edge 11 of the T-shaped drawbar 2 shown in FIG. 10 fits snugly.
  • the slope of the curved branches 13, 14 is so great that, when a pulling force acts on the leg 4 of the drawbar 2 in the direction of the longitudinal axis DL of the drawbar, the tapered end pieces 17, 18 immediately against the guide surfaces 23, 24 of the curved branches 13, 14 Concerns come, ie that there is no play between the guide surfaces 23, 24 and the drawbar 2.
  • the curved branches 13, 14 preferably form circular sections, the center points of which lie at the outer end points of the rear edge 12 of the guide template 1.
  • the springs 26, 28 preferably represent leaf springs which are advantageously formed in one piece with the T-shaped drawbar 2.
  • a particularly suitable material for the drawbar 2 and the springs 26, 28 is a thermoplastic known under the trade name "Hostaform", which is characterized by favorable suspension and sliding properties as well as high mechanical strength. In principle, however, other types of abrasion-resistant plastics or metals can also be used.
