Definitions

  • This invention refers to a toy vehicle which, when it is pushed, momentarily drives a high-inertia element which returns the energy stored in it when the exterior push is completed.
  • the vehicle has the high-inertia device positioned in such a way as to reduce the friction losses therein, as well as conferring the vehicle with self-alignable features which are improvements on known embodiments.
  • US patent 800,741 disclosed a toy consisting of a hollow figure representing a dancing couple with a ball trapped inside it. This makes the figure freely rotate and move in all directions when it is positioned on a plane which is inclined in one direction or the other. This makes use of the high degree of freedom derived from the spherical shape of the ball, but is unaware of the possibilities that could be derived from a heavy ball.
  • the toy is not designed to be pushed by the hand, and this is confirmed in the drawings, which show that the ball is made from glass, and not metal.
  • Document US 4,156,986 describes a small, very economic, toy vehicle, designed to be added to cereal packets as a gift, manufactured in injected plastic, containing a high-inertia disk therein which rotates around a transversal axis while it is rolling along a surface. Once the vehicle has been push-started, the movement continues for longer than it would should the vehicle not have the high-inertia rotating disk.
  • the principal path is determined by the ball, and it is the vehicle that rotates around it, with the front and the rear moving simultaneously.
  • the vehicle's movement depends on the position of its centre of resistance (defined by the friction of the wheels) in relation to the inertia ball.
  • one objective of this invention is a toy vehicle running on inertia with improved self-alignment features, with high inertia and low friction losses.
  • the objective proposed is achieved in the vehicle of the invention by the positioning of a trapped ball, of considerable inertia in relation to the weight of the vehicle, inside the cavity formed by the upper body and the lower chassis; this ball rolls freely over the surface on which the toy vehicle is positioned.
  • the opening in the vehicle's chassis, through which the ball can be seen, is a straight sided polygon, this replacing the linear contact of the prior art with one or two points of contact.
  • the polygonal opening is in front of the vehicle's centre of resistance, defined as the virtual point of action resulting from the different friction forces derived from the weight of the wheels on the surface plane.
  • the centre of resistance will be on the intersection of the bisections of the rectangle defined by the points of contact of the wheels on the surface. Otherwise, the centre of resistance will move towards the wheels which support a greater percentage of the vehicle's weight or, in general, have greater friction, which can be modified by altering the width and roughness of the wheels.
  • the vehicle's centre of resistance can be evaluated by calculations or, preferably, by empirical testing. The choice of the distance between the point of contact of the ball with the surface and the centre of the polygonal opening will depend on the degree to which it is desired for the toy vehicle to be manoeuvrable. The vehicle's characteristics can easily be modified, depending on whether it is a sports car or a heavy goods trailer, for instance.
  • Figure 1 shows the diagram of force and movement produced during the self-alignment of a vehicle manufactured according to the prior art.
  • the inertia ball (5) acting on the circular wall (9), generates a force R1 which causes a movement M1 which tends to move the front of the vehicle in the direction of the movement, causing the vehicle to rotate in relation to a centre of rotation 0 which, in these conditions, is between and near to the rear wheels.
  • the movement is quite sudden and not very natural, and it causes high losses derived from friction between the inertia ball (5) and the circular wall (9).
  • the inertia ball (5) is trapped between an upper body (2) and a chassis (3) in which there is a polygonal opening (4) through which the inertia ball (5) can roll on the surface (8), but through which it does not pass when the vehicle (1) is lifted from the surface (8). See figure 3.
  • the inertia ball (5) will have to be inserted between the upper body (2) and the chassis (3) before being joined by any known method, and the wheels can be installed rotating on the corresponding wheel shafts (7) or fixed, and merely decorative, forming part of the upper body (2) or the chassis (3), which will reduce the cost of the product considerably.
  • the figures show a polygonal opening (4) in the form of a hexagon, which has been seen to be an optimal solution, but it could equally be square, triangular or with more sides, although in this case we lose the advantages of low friction the nearer we come to a circle.
