Definitions

  • the invention relates to a device for power transmission in toy models, consisting of a flexible shaft according to the preamble of claim 1.
  • a steering shaft consisting of a wire and mounted in a flexible guide tube to the steering column of the vehicle on one side and to a crank on the other side.
  • the steering column and crank have coupling pieces in which the steering shaft is firmly clamped.
  • Such a device is thus an integral part of a finished toy model and therefore not suitable for universal use as a component of a construction kit.
  • functions are often required in toy models in which pressure and tensile forces are to be transmitted.
  • Bowden cables which, however, are not suitable for pressure transmissions.
  • the invention has for its object to provide a device for power transmission for toy models that is universally applicable and can be used for different types of power transmission.
  • the plug-in part of the force-transmitting element which can be provided, for example, with a crank, actuating button or the like, is inserted into the centrally arranged hole of the coupling piece to such an extent that the two opposing locking lugs in the transverse opening of the Engage the coupling piece.
  • the wedge tip arranged on the spring bolt engages in the slot and presses the two legs with the locking lugs apart. This ensures that all types of power transmission are locked against unintentional loosening.
  • the wedge tip is disengaged from the slot by pushing back the spring bolt and at the same time the element is pulled out of the hole in the coupling piece.
  • the device for power transmission is particularly suitable for toy models that are assembled from parts of a construction kit.
  • the device can be used in many ways and can be used for all types of power transmission. Since both the shaft and the guide tube are flexible, force redirection is possible in three-dimensional space and at any angle. The angular position is determined by the flexible guide tube, which for this purpose is provided at its ends with flanges which have connecting means on their peripheral surfaces. The guide tube is installed and fixed in the toy model via these connecting means.
  • the flexible shaft and the coupling pieces are advantageously made of plastic. This makes it possible to integrally molded the spring bolt on one side of the opening in the coupling piece.
  • the coupling pieces can be connected to the flexible shaft either by welding, gluing, jamming or the like.
  • the flexible guide tube is first produced in the first spray pass and, after the core has been pulled out, the flexible shaft with the coupling pieces are injected in the second spray pass. While the flexibility of the shaft is achieved through the use of appropriate plastics, the flexibility of the guide tube is achieved through meandering structured openings in its jacket.
  • the bore of the coupling piece and the part of the force-transmitting element engaging in the coupling piece can have a mutually matching profile. Without this profiling, the torque transmitted via the locking lugs engaging in the opening in the coupling piece.
  • the device for power transmission in toy models consists of a flexible shaft 1, which is mounted and guided in a flexible guide tube 2.
  • the flexibility of the guide tube is achieved through meandering structured openings 3.
  • Flanges 4 are molded onto the two ends of the guide tube 2, which have connection means 6 on their circumferential surface for connection to other components 5 of a construction kit. With these flanges different curvatures of the guide tube 2 and thus also the flexible shaft 1 can be fixed.
  • Coupling pieces 7 are arranged at the two ends of the flexible shaft 1 by welding, gluing or injection molding. These coupling pieces 7 have a transverse opening 8, into which a centrally arranged hole 9 opens out relative to the shaft 1.
  • This hole 9 serves to receive a force-transmitting element 10, which can be provided, for example, with an actuating button 11, crank or the like.
  • the plug-in part of the force-transmitting element 10 has a slot 12 and two locking lugs 13 projecting beyond the outer diameter of the plug-in part.
  • a wedge tip 15 arranged on the spring bolt 14 engages in the slot 12 and presses the two legs into the latching position.
  • the one-sided injection molding of the spring bolt 14 on an edge of the opening 8 of the coupling piece 7 creates a movable lever which can be pushed back to unlock the force-transmitting element 10.
  • the wedge tip 15 is disengaged, so that the locking lugs 13 disengage and the force-transmitting element 10 can be pulled out.
  • the force-transmitting element 10 can transmit pressure and tensile forces and torques to the opposite end via the coupling piece 7 and the flexible shaft 1.
  • the plug-in part of the force-transmitting element 10 and the hole 9 of the coupling piece 7 have a mating profile 16 formed by surfaces.
  • the flexible guide tube 2 with the two flanges 4 and the flexible shaft 1 with the coupling pieces 7 can be produced in a two-component injection molding process. It is expedient to spray the guide tube with the flanges in the first spraying step and, after pulling out the core and changing the outer shape, spraying the flexible shaft with the coupling pieces in a second spraying step.
