• the first and second lateral chassis portions 40, 70 are coupled with the central chassis portion so as to pivot with respect to the central chassis portion 30 in a common plane, which is generally parallel to the plane of Fig. 3.
• the first lateral chassis portion 40 includes a reversible electric motor 46 enclosed within a first cover 50 on the first chassis portion 40.
• the motor 46 is drivingly coupled with at least one and preferably with each of the road wheels 42, 44 supported on the lateral chassis portion to rotate the driven wheels in the same direction through a gear train (not seen in any of the figures) within the chassis portion 40.
• the gear train is substantially identical to that shown in U.S. Patent No.
• the first longitudinal end 12 of the first lateral chassis portion 40 is coupled with the first longitudinal end 12 of the central chassis portion 30 through a link 54 (best seen in Fig. 3).
• Link 54 has a proximal end pivotally coupled to the central chassis portion 30 to pivot about a pivot axis transverse to the major planes of the vehicle.
• the distal end of the link 54 is also provided with a transverse guide member in the form of a protruding pin or pin equivalent 56, which is received in and slides along a longitudinally extending slot 52 on an inner lateral side of the first lateral chassis portion 40.
• Fig. 2 depicts the direct pivotal mounting of the first lateral chassis portion 40 with the central chassis portion 30 at the second longitudinal end 14 of the vehicle.
• a pivot member (e.g. pin) 62 is transverse to the major plane of the vehicle 10 and extends through overlapping flanges 30a, 30b of the central chassis portion 30 and 40a, 40b of the first lateral chassis portion 40.
• a torsional coil spring 64 is positioned around pivot member 62.
• a first tang (not illustrated) of the spring 64 is engaged with a flange of the first lateral chassis portion 40.
• a second, opposing tang (not illustrated) is similarly engaged with a flange element of the central chassis portion 30.
• the torsional coil spring 64 is located to bias the first lateral chassis portion 40 inward towards the central chassis portion 30 and the inward position shown in Fig. 1.
• the bias of the spring 64 can be overcome during operation of the vehicle 10 to cause one or both lateral chassis portions 40, 70, to pivot outwardly from the central chassis portion 30, as is illustrated in Fig. 3.
• a power supply 38 preferably a rechargeable battery pack, is preferably located at the extreme second longitudinal end 14 of the vehicle 10 on the end of the central chassis portion 30 to shift the center of gravity of the vehicle 10 closer towards the second longitudinal end 14 of the vehicle to assist the vehicle 10 in performing certain types of stunts, particularly the stunt shown in Fig. 3.
• each lateral chassis portion 40, 70 is provided with a transparent cover 60 at the first longitudinal end of the chassis portion 40, 70 over a light source, preferably a high intensity light emitting diode ("LED") 36 (see Fig. 1).
• each link 54 is formed from a transparent polymer material and also includes a high intensity LED 36 as seen in Fig. 3 at its proximal end where it is pivotally coupled by link 54 with the central chassis portion 30.
• Control of itinerant movement of the vehicle 10 is conventional.
• the vehicle includes control circuitry 100 indicated in block diagram form in Fig.
• the operation of the motors 46, 46' are controlled by the microprocessor 104 in response to control signals received by the receiver 102 from a remote control unit 112 generating and transmitting wireless maneuver control signals.
• RF radio frequency
• the vehicle 10 is propelled by controlling each motor 46, 46' to rotate the various road wheels 42, 44 in the same direction at the same speed and is steered by controlling the motors to drive the wheels on either lateral side 16, 18 of either lateral chassis portion 40, 70 differently, either in different directions or at different speeds or both.
• the vehicle 10 can be made to spin in place. Centrifugal force causes the free longitudinal end of each lateral chassis portion 40, 70 at the first longitudinal end 12 of the vehicle 10 to spread apart.
• lateral chassis portions 40, 70 causes a further shift of the center of gravity of the vehicle 10 towards the second longitudinal end 14 so that, if the vehicle 10 continues to be spun in place, it will raise its first longitudinal end 12 and spin about its second longitudinal end 14 in an upright manner as seen in Fig. 3.
• vehicle 10 tends to be supported on the corners and sidewalls of its road wheels 44 at the second end 14 of the vehicle 10 during such maneuvers.
• the light sources 36 conventionally might be hard wired with the battery power supply 38 to be constantly on when on-off-switch 110 is set to the ON position, closing the circuitry through the battery 38, according to the present invention, the light sources 36 preferably are individually coupled into circuit using a switch (e.g., a transistor not separately depicted) controlled by the microprocessor 104. In this way illumination of each light source 36 can be individually and selectively controlled with the microprocessor 104.
• the control circuitry 100 can be configured to operate the light sources 36 in more than one mode of operation.
• the control circuitry 100 and, more preferably, the microprocessor 104 is configured to operate the light sources 36 in at least two different modes of operation.
• control circuit 100 being configured to selectively supply power to illuminate at least one light 36 in response to a signal indicating the vehicle 10 is performing a particular maneuver.
• vehicle 10 performs a particular stunt in which it stands up on its second end 14 and spins in place with its lateral chassis portions 40, 70 pivoted away from the central chassis portion 30.
• vehicle 10 is provided with a momentary closure switch 80 (Fig. 4) positioned to change states when at least one of the lateral chassis portions 40, 70 is pivoted away from the central chassis portion 30, which occurs when the vehicle 10 is performing some type of spin maneuver.
• the signal is thus generated by a switch (80) adapted to detect a position of at least one of the lateral chassis portions 50, 70 relative to the central chassis portion30.
• the microprocessor 104 is preferably configured to operate LED's 36 in two different modes depending upon the state of switch 80, as communicated to the microprocessor 104 by a signal generated by the switch 80 and sent to the microprocessor 104 along line 82. Unless the lateral chassis portion 40 or 70 is pivoted away from the central chassis portion 30, switch 80 is in a first state and the microprocessor 104 responds to that state in a first mode of operation of the LED's 36, for example illuminating some (e.g. the lateral chassis mounted pair) or all of the LED's continuously.
• the microprocessor 104 When the switch 80 is in another state indicating that at least one of the operably coupled lateral chassis portions 40, 70 is pivoted away from the central chassis portion 30, the microprocessor 104 operates in another mode, for example flashing some (e.g., either the link pair or the lateral chassis pair) or all of the LED's 36.
• Fig. 5 graphically depicts a suggested sequence of operating the light sources 36, which includes flashing all of the LED's 36 in a varying manner over time.
• power to at least one light 36 is modulated as a function of time to vary a level of illumination intensity provided by the at least one light.
• Fig. 5 is a chart of LED illumination intensity over time.
• the variation in operation i.e., the illumination intensity of the LED, changes in consecutive time period blocks indicated Tl, T2, etc. While they are illustrated as being equal, they need not be.
• Tl e.g.
• the LED's 36 are varied from zero to fifty percent of maximum intensity and back to zero twice at a uniform rate over the period (i.e., as depicted over five seconds) or, if desired, over a substantial portion (e.g. about four seconds) of the period.
• switch 80 remains in the second state after the end of the first period Tl, the microprocessor 104 enters the second time period T2 and second mode of illumination during which the LED's 36 are varied from zero to seventy-five percent of maximum intensity and back four times at a constant rate over the period T2. If the switch 80 remains in the second state after period T2 (i.e.
• the third period T3 and third mode are entered in which the intensity is varied from zero to a maximum eight times at a uniform rate. If the fourth consecutive time period T4 is entered, the LED's 36 are illuminated constantly at full intensity for the full period. If the fifth period T5 is entered, the LED's are turned off for the length of the period. Thus, T4 and T5 together constitute one on-off cycle. If a sixth period, T6, is entered, the LED's 36 are operated intermittently with a full off period between pairs of consecutive spikes of one-hundred percent illumination as depicted or between individual spikes of illumination (not separately shown) to create a strobe effect. As consecutive time periods continue to be entered, other modes of illumination can be created.
• previous practiced modes can be repeated or the last mode repeated indefinitely.
• Other possible modes include varying intensity levels down to a non-zero level and illuminating the light sources in series or in various pairs or randomly.
• the microprocessor 104 might utilize a stored look-up table to control the different illumination modes.
• the microprocessor can be programmed to respond to different commanded operations, for example illuminating in a first mode when commanded to go forward, in another mode when commanded to reverse, in still another mode for turning, yet another mode when stopped and yet another mode when spinning in place.
• the vehicle is capable of transforming itself as described, for example, in US Patent Nos. 5,762,533; 5,474,486 and 5,332,469 or is capable of performing unusual stunts as described, for example, in US Patent Nos.
