Definitions

  • the invention relates to a flexible shaft for toy models according to the preamble of claim 1.
  • Shafts are used for power transmission in toy models or corresponding model arrangements for different purposes, for example for driving or steering a vehicle.
  • 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 that also have to transmit pressure and tensile forces.
  • Bowden cables which, however, are not suitable for the transmission of compressive forces.
  • the invention has for its object to provide a flexible shaft for toy models that can be used universally and is particularly suitable for torque transmission and transmission of tensile and compressive forces.
  • the flexible shaft connection elements are arranged, which are flexibly connected via a plurality of rigidly connected ring elements made of plastic.
  • the ring elements have the advantage over a rod-shaped shaft that on the one hand a high flexibility of the shaft is obtained, while on the other hand a high torque can also be transmitted.
  • the ring elements which are preferably offset at an angle of 90 ° to one another, have the advantage that the flexible shaft is equally flexible in every direction and can transmit a high torque in any position.
  • the ring planes enclosed by the ring elements preferably lie on their central axis when the shaft is aligned. This gives a homogeneous torque transmission, i. H. each ring element is equally stressed during torque transmission. When the flexible shaft is bent, however, the bending stress in the individual ring elements changes depending on the position of the shaft.
  • the flexible shaft is preferably made in one piece from plastic by injection molding, the connection points between adjacent ring elements forming intersection points.
  • the ring elements arranged in series can be partially or completely enclosed by a guide tube, as a result of which higher compressive forces and higher torques can be transmitted without problems.
  • a guide tube or the like is also required if tensile forces are to be transmitted when the shaft is bent.
  • the flexible shaft To connect the flexible shaft to an input shaft or an output shaft, the latter has coupling pieces located on the end faces of each of its connecting pieces.
  • connection elements 1, 2 at its two ends, which are connected to one another via a series of ring elements 3.
  • Successive ring elements 3 are in each case rotated by 90 ° to one another and are connected to one another in one piece via crossing points 4.
  • the ring planes 5 enclosed by the ring elements 3 run through the central axis 6 of the just-aligned flexible shaft.
  • the flexible shaft is made in one piece from plastic using the injection molding process, and depending on the requirements and field of application, a correspondingly elastic or harder plastic can be used.
  • the flexible shaft has coupling pieces 7, 8 on the end faces on the connecting elements 1, 2, which are profiled in such a way that a torque transmission and also a transmission of compressive and tensile forces are possible is.
  • the section A-A is shown enlarged in Figure 2.
  • the ring elements visible here are designated by the reference numbers 31, 32.
