Definitions

  • the present invention relates to a toy vehicle and, in particular, to a toy vehicle whose physical behaviour and operating characteristics can be selectively altered by a child playing with the toy vehicle, preferably by moving a simulated gear-shift lever, which permits the toy vehicle to perform multiple actions depending on the position of the operative components as selected by the gear-shift lever.
  • Toy vehicles such as toy automobiles which simulate the appearance and operation of real automobiles and which are capable of being self-propelled by an internal motor or the like, have become popular with children of all ages.
  • One such type of toy vehicle includes what has been commonly known as a pull-back motor.
  • the rear wheels of the toy vehicle are coupled to a motor which includes a spring which is tightened as the rear wheels are rolled backwards along a surface.
  • the spring becomes tightened so that when the vehicle is released, the spring will relax and transfer its energy via torque to the rear wheels causing them to rotate in a forward direction to propel the toy vehicle in a forward direction.
  • Mechanisms of this type are described in US-A-4,077,156 and US-A-3,798,831.
  • Other than being capable of changing the acceleration and speed of such toy vehicles depending upon the amount of energy stored in the spring only one type of action, namely forward action on all four wheels is possible.
  • a toy vehicle having a motor which permits self-propulsion could be developed to perform multiple actions such as wheel stands, turning, spinning-out and the like. It would be even more desirable if such a toy vehicle could perform such multiple actions as controlled by a lever which simulates a real gear-shift lever in an automobile having a manual transmission whereby the placing of the gear-shift lever in a desired gear position in the toy vehicle results in different types of action to be performed by the toy vehicle.

  • the centre of gravity of the toy vehicle 10 will be in a normal position such that, after torque is applied by the motor 20 to the rear wheels 26a and 26b, as the toy vehicle 10 moves forward, the vehicle will either run straight on all four wheels or will perform a wheel stand if a sufficient amount of rotational energy is supplied to the rear wheels to cause the front of the toy vehicle to lift up.
  • the weight 32 on the left side of the toy vehicle 10 is pivoted rearwardly and locked in a rearward position.

  • Both the projections 38 and 39 are lowered through the chassis 12. The centre of gravity of the toy vehicle 10 is moved to its maximum rear position.
  • the front wheels of the toy vehicle will readily lift off the ground and the vehicle will turn right or left depending upon the friction characteristics of the surface on which it is running.

This permits the cover 230 and the motor 220 thereunder to be slidable on the chassis 202 in the directions indicated by arrow A ( Figure 28).
  • a shift lever mechanism 240 is provided and includes a U-shaped section 242 having downwardly extending arms 244 and 246 and a shift arm lever 248 which extends in an upward direction through a slot 204a in the car body 204. Pivot pins 244a and 246a on the outer surface of the legs 244 and 246 respectively are held in openings 210b and 212b formed in the rails 210 and 212 respectively.

  • the wheel base is lengthened slightly so that the longest projection 260 is positioned only slightly behind the rear wheels.
  • the motor 230 drives the vehicle 200 in a forward direction and a wheel stand is performed, the projection 260 will move up and away from the ground and the right projection 264 will contact the ground thereby lifting the left rear wheel 216a. This causes the right rear wheel 216b to power the vehicle in a spin or turn to the right.
  • Figures 31 and 31A show the toy vehicle 200 with the shift lever 248 in the third gear position.
  • the rear wheels are moved further back thereby lengthening the wheel base and moving the right projection 264 behind the rear wheels. Accordingly, during a wheel stand as the vehicle 200 is powered forward, the projections 260 and 264 will move upward and the shortest centre projection 262 will contact the ground. This action aids the toy vehicle 200 in running in a straight line during the wheel stand since the projection 262 is centrally located.
  • Figure 32 shows the toy vehicle 200 with the shift lever 248 in the fourth gear position.
  • the rear wheels are moved back a sufficient amount to create a relatively stable wheel base for the toy vehicle.
  • There is generally sufficient weight in front of the rear axle to prevent the toy vehicle from performing a wheel stand while moving forward. This forward movement will be in straight lines if weighted uniformily of the central axis from front to back. Movement to left or right can be achieved by appropriate weighting to one side of this central axis.
  • the front wheels may be elliptical in shape which would cause the front end to be raised when in fourth gear since the front end of the vehicle would be thrown upward by the rotating elliptical wheels. Other forms of weighting may also be employed to provide this effect.
  • Figure 33 shows the toy vehicle 200 in a fifth gear position. The distance between the front and rear wheels is greatest in the fifth gear position so that the wheel base is longest. This produces a stable ride without wheel stands being performed by the toy vehicle.
  • the present embodiment under discussion like the embodiment shown in Figures 1 to 3 provides a multi-action toy vehicle in which the physical behaviour and operating characteristics of the toy vehicle can be determined by the operator by setting a simulated gear-shift lever in a selected gear position.
  • the first embodiment utilizes pivoting weights to change the centre of gravity of the toy vehicle
  • the present embodiment utilizes a change in the wheel base length to alter the physical behaviour and centre of gravity of the toy vehicle.

  • the lower portion of the lever 330 is adapted to contact the extensions 308 and 310 of the arms 300 and 302, respectively, dependent upon the position in which lever 330 is situated.
  • the lower portion of the lever 330 When in the first gear position, the lower portion of the lever 330 will press against the extension 310 to thereby pivot the arm 302 such that the projection 322 extends through the chassis 12 to raise the rear wheel 26b when the toy vehicle is performing a wheel stand. Since the weight 332 is shifted to the rear of the toy vehicle, the addition of this weight to the rear will cause the vehicle to perform a wheel stand. The left rear wheel 26b is raised turning the toy vehicle to the left.
  • the weight 332 is shifted forward centrally and the vehicle will move forward on all four wheels in a straight line if not otherwise weighted.
  • the weight 332 In the third shift position, the weight 332 is shifted to the rear, but the lower portion of the lever 330 does not sufficiently contact extensions 308 or 310, and hence, projections 314 and 322 do not project through the chassis 12.
  • the toy vehicle In the third gear, the toy vehicle will perform a wheel stand while travelling in the forward direction, its front wheels being lifted off of the running surface.
  • the weight 332 is again shifted forward but to the right side of the vehicle. Extensions 308 and 310 are not contacted, and the vehicle will essentially run forward on all four wheels. Depending on the relative weighting, the. weight is to the right of the vehicle and this will tend to pull the vehicle to this side.
  • the weight 332 is shifted to the rear right side of the toy vehicle and the lower portion of the lever 330 presses against the extension 308 to cause the projection 314 to project through the bottom of the chassis 12.
  • the vehicle will perform a wheel stand in the forward direction and the projection 314 will contact the surface on which the toy vehicle is riding, thereby lifting the rear wheel 26a off of the ground as shown in Figure 36.
  • the slots 313 and 321 are provided in the arms 300 and 302, respectively, to receive a leaf spring such as a leaf spring 350 as shown in Figure 36.
  • the leaf springs provide a bias to the arms 300 and 302 such that they remain in a neutral position when not pressed by the disk 340.
  • arms 300 and 302 may be weighted as in the embodiment shown in Figures 1 to 21.
  • the second embodiment of vehicle may be weighted as shown in Figures 1 to 2. Futher the second and third embodiments may also be combined.
