Definitions

  • the present invention relates to improvements in toy electric cars, specifically in those which pick up the current from the actual running track, the latter having guide grooves for these cars, encased in metal tracks, which constitute the electrical supply terminals for the corresponding cars, whose speed may vary as a function of the voltage applied to the said electrically conducting tracks, from a voltage regulator or changer with which each controller is furnished.
  • the improvements of the invention are aimed at achieving, for a specified layout in the grooved track, a substantial increase in the mean speed which the car can attain, while keeping the motor thereof unchanged.
  • toy electric cars of this type incorporate, at the forward end of their chassis and centrally, a guide mechanism consisting of a small disc mounted with freedom of rotation on the chassis, from which disc there emerges underneath a flat pin intended to engage in the corresponding groove of the grooved track on which the car is to travel. Both sides of this pin are furnished with brushes which make permanent contact with the electrically conducting tracks which encase the aforementioned groove and which are duly connected to an electric micromotor installed in the aforementioned chassis, the speed of the vehicle depending, as stated earlier, on the electric voltage applied at each moment to the corresponding pair of electrically conducting tracks.
  • Toy electric cars of this type on account of their low weight, of the order of 80 grams, are theoretically capable of attaining very considerable speeds, which in practice are not achieved due to the winding layout of the grooved tracks.
  • On the curves due to centrifugal force, the car parts company with the track when it exceeds a specified speed. This is due to the guide pin being unable to be retained in the corresponding guide, precisely on account of the lightness of the car in its forward region, owing to which these toy cars operate better with rear-wheel drive. For this reason, and since the guide mechanism is located in the forward part of the chassis, the propulsion micromotor is also set up close to its rear axle.
  • cars of this type which are provided, close to their back and live axle, with a permanent magnet which tends to press the chassis against the electrically conducting metal tracks and, consequently, to press the wheels against the running track, which undoubtedly improves the grip and, consequently, also improves the getaway acceleration. Nevertheless, the mean speed remains limited due to the problem mentioned earlier relating to instability on curves.
  • the improvements proposed by the invention solve the difficulties mentioned earlier by considerably improving the stability of the car on curves and, consequently, allowing a considerable increase in the mean speed thereof, on a specified circuit, which increase may amount to more than 50%.
  • the electric propulsion micromotor of the car which constitutes one of the heaviest elements thereof, to be located in the forward end of the chassis, immediately behind the guide mechanism.
  • Figure 1.- shows a plan view from above of the chassis corresponding to a toy electric car made in accordance with the improvements which are the subject of the present invention.
  • Figure 2.- shows a plan view from below of the same chassis.
  • a toy electric car made in accordance with the improvements which are the subject of the invention, is constructed from a chassis (1) on which the corresponding bodywork, not represented, is to be mounted.
  • This chassis (1) as in any conventional car, is provided with a rear axle (2), on which the driving wheels (3) are set, for which purpose the said axle (2) possesses a crown wheel (4) with which there enmeshes the driving pinion (5) of an electric micromotor (6), supplied via the electrically conducting tracks defined on the actual running track.
  • front wheels (7) rotate freely and have at their forward end a guide mechanism consisting of a disc (8) mounted with freedom of rotation on a pivot or vertical axle (9), provided in its lower face with a longitudinal pin (10), consequently swinging in the lateral direction, intended to travel within the corresponding groove, of the running track.
  • a guide mechanism consisting of a disc (8) mounted with freedom of rotation on a pivot or vertical axle (9), provided in its lower face with a longitudinal pin (10), consequently swinging in the lateral direction, intended to travel within the corresponding groove, of the running track.
  • a guide mechanism consisting of a disc (8) mounted with freedom of rotation on a pivot or vertical axle (9), provided in its lower face with a longitudinal pin (10), consequently swinging in the lateral direction, intended to travel within the corresponding groove, of the running track.
  • brushes (11) Secured to the aforementioned disc (8), also underneath and on both sides of the pin (10), are brushes (11) which under normal conditions make permanent contact with the electrically conducting tracks which encase the corresponding guide
  • the improvements of the invention consist in displacing the electric micromotor (6), which conventionally occupies the representation shown with a dashed line in Figure 1, where it appears referenced (6'), to close to the forward end of the chassis (1), locating it immediately behind the guide mechanism (8), so that the centre of gravity of the car substantially approaches the guide pin (10), in order considerably to increase the speed required to produce derailment.
  • an extender rod (14) which is coupled to the output shaft (15) of the motor (6) by any appropriate means, such as for example with the collaboration of a helical spring (16) which through its inherent elasticity tends to become strangulated on the shaft (15) and on the rod (14), which terminates via its opposite end in the conventional driving pinion (5) for the crown wheel (4) of the live axle (2).
  • the car without modifying either its electric micromotor (6) or its weight, brings the latter to bear with greater intensity on the forward end thereof, thereby entailing greater difficulty in the guide pin (10) uncoupling from the corresponding groove on curves, thereby allowing the latter to be taken at a considerably greater speed.
  • this forwards displacement of the centre of gravity entails a lesser weight of the car in its back region, which would have a negative repercussion on the grip of the driving wheels (3) and, consequently, on the conditions of acceleration.
