Definitions

  • the invention relates to a claw coupling for, in particular electrical, play and model railways with pre-decoupling, with a claw that can be hooked in from the side in a rigid hook of the respective counter-bearing part and can be swiveled in a horizontal plane, through a claw on its in a bore supported and downwardly projecting bearing pin engaging clutch lifter of a decoupling track against the force of gravity can be lifted out of its coupling position into a decoupling position.
  • Such a claw coupling which has become known as the so-called Fox coupling and is described in German Offenlegungsschrift 2,041,361, enables short couplings to be built which, in addition to coupling and uncoupling, at the same time enable pre-decoupling by means of a decoupling track in such a way that the carriages are raised with the claws raised Push any point of the track system and have it parked and only after a "pulling off" of the vehicles, in which these are first separated, a new coupling is possible.
  • the difficulty with the Fox coupling heads is that the claw has to be clamped into the coupling position by a swivel return spring, this being the bearing tang surrounding torsion spring is supported on a thickened head on its underside, which at the same time generates the vertical restoring force.
  • the invention is therefore based on the object of designing a claw coupling of the type mentioned in such a way that reliable coupling and holding of the couplings in the engaged position is ensured even without a return spring.
  • the invention provides that the bearing bore and the bearing pin are each arranged on the outer edge of the bearing part or the claw and that the bearing part has a starting mandrel for the inner arm of the claw of the respective mating coupling part.
  • the bearing bore and the bearing pin are each arranged on the outer edge of the bearing part or the claw and that the bearing part has a starting mandrel for the inner arm of the claw of the respective mating coupling part.
  • the claw Due to the displacement of the fulcrum according to the invention, the claw is always rotated inwards in connection with the starting mandrels when two carriages move together and - by appropriate design of the length of the starting mandrel - is held in this inwardly rotated coupling position.
  • the start-up mandrel is dimensioned in such a way that it prevents the respective counterclaw from swinging outwards into a decoupling position. The uncoupling can then only - as desired per se - take place via a uncoupling track and lifting the claw.
  • the starting mandrel which is preferably molded onto the bearing part, is designed to be axially resilient, which is readily possible by appropriate shaping of the plastic material, even with harder plastic parts.
  • the axial spring travel which is necessary so that the mandrel always rests on the inner arm of the counter-claw and thus reliably prevents it from swinging open due to vibrations during operation, is so small that no particularly great elasticity of the material is necessary for this.
  • the bearing design is such that when the bearing pin is lifted, the claw inwards is pivoted and placed on the counter bearing part.
  • this can be achieved particularly simply by arranging on the inner arm of the claw a pivot pin passing through an elongated hole of the bearing part with a run-on slope which, when the claw is raised, abuts the edge of the elongated hole via a decoupling track and thus pivots the claw forces inside.
  • Each coupling head comprises a bearing part 1 with a rigid, outwardly pointing hook 2 at the front end and a plug-in connection section 5 for insertion into standardized receiving shafts 6, for example in accordance with the European model railroad standard NEM 362.
  • a pivot pin 20 is formed on the inner leg 7b of the claw 7 and is provided at the lower end with a thickening 22 forming a run-on slope 21.
  • This pivot pin passes through an elongated hole 23 of the bearing part.
  • the run-up slope 21 is designed such that when the claw 7 is raised via a decoupling track 9, which, in contrast to previously known Fox couplings, it is not the bearing journal but this pivot pin 20 that forms the decoupling pin, the run-up slope 21 in connection with the elongated hole edges 23 forcibly pivots the claw 7 causes inward into the pre-uncoupling position shown in FIG. 4.
  • the claw After driving over the coupling track 9, the claw falls in this inwardly pivoted St down and lies on the respective counter-bearing part 1, so that a new coupling is only possible after pulling the car from each other, so that the claw 7 in again the normal lower position can fall down.
  • Gravity alone serves as the vertical restoring force.
  • the starting mandrel 24 must press on the shoulder 7b, so that the entire claw is pressed inwards and the hook ends 10 also remain on the hook 2 of the counter-coupling. This can be achieved, for example, in that the starting mandrels 24 are increased in relation to the surface 25 of the coupling parts, that in the sliding position, in which the coupling parts are more pushed together than in FIG.
  • the starting mandrels are also in the raised plane of the part 7b of the claw.
  • the part 7b would then immediately abut the raised starting mandrel 24 and thus prevent it from pivoting outwards.
  • the bearing part in the region 26 could, for example, be provided with a cutout, so that the coupling parts can move even closer to one another and thus even fewer possibilities for the pivoting movement of the Claw are given.
  • the chamfers 27 on the hook heads 10 and the counter chamfers 28 on the rigid hooks are necessary. This is because they ensure that the hook heads 10 are guided safely over the hooks 2 during the coupling process, even if they should first be pivoted somewhat inwards. Only when they are swung open so far and the hook heads have come directly behind the hooks 2, the starting mandrels 24 may come into effect.
  • the starting mandrels 24 should also be arranged in such a way that they secure the coupling against shear movements closely adjacent to one another laterally. Such lateral displacements of the couplings against each other would otherwise have to be intercepted by the hook heads 10 of the claws, which could break out in the process.
  • the design can be such that the starting mandrels 24 have a low axial resilient displaceability, which can be achieved, for example, by the indicated tip, so that the starting mandrel always rests resiliently on the inner arm 7b of the counter-claw 7 and thus shakes it "the clutch is safely prevented even when jogging.
