  • Patent number: 9387411
    Abstract: The educational toy car includes a framework having a pair of rear wheels and a pair of front wheels. The front wheels are pivotably connected as well as rotatably connected with the framework, and rotate in concert with one another via a steering tie rod. The framework includes an engine block with a plurality of piston members that work in concert to visibly rotate a transmission member located elsewhere in the framework. The transmission member connects to a drive gear that includes a drive shaft extending rearwardly within the framework, and to in mechanical connection with a rear differential. The rear differential is in mechanical connection with the pair of rear wheels. The pair of rear wheels are rotatably connected with the framework, and are rotated upon movement of the piston members or the transmission member or the drive shaft or the rear differential.

    Abstract: An eccentric wheel structure of a wind up toy car includes a base, a casing and a wind up motor. The wind up motor is disposed between the base and the casing. The wind up motor includes a wheel axle and two wheels. The wheel axle is inserted through the wind up motor. The two wheels are coupled to two sides of the wheel axle. Particularly, the two wheels are eccentric relative to the wheel axle. When the wheel axle is turned, the wind up toy car is staggered to move by the two eccentric wheels. Compared to a traditional wind up toy car that is erect to move, the present invention is more funny and special.

  • Publication number: 20110053453
    Abstract: An educational and entertaining toy vehicle that includes a body member that is designed for including a mechanical music box. The music box is designed so it is coupled via a ratchet clutch and gears to at least one vehicle wheel. The forward rotation of such wheels drives the music box. Reversing the vehicle winds a spring. This spring drives the music box and vehicle forward on release. The release of said spring is controlled by a speed regulator. The toy vehicle of this invention includes rubber like material on the surfaces of the wheels with debossed numerals, letters or symbols. These replaceable rubber like tires provide increased friction and a means for printing such debossed characters when the vehicle is moved. The toy vehicle is further enhanced by including a toy figure that is representative of the included tune.

  • Publication number: 20080166947
    Abstract: The present invention relates to a spring-powered toy vehicle with a front body portion, a separable rear body portion, rotating wheels and a spring propulsion system. When the rear body portion is pulled away from the front body portion and released, the spring will pull the rear body portion back into the front body portion, thereby causing the vehicle to move forward. Parallel vehicle guides prevent the rear movable body portion from pulling away in a non-axial direction, thus guiding the propelled toy vehicle in a straight line. Other aspects provide interchangeable and replaceable springs, and body portions. Additionally, vehicle choices include autos, trucks, motorcycles, planes, and construction equipment. A launcher is included that provides a stable platform for launching the vehicles and additionally imparts, through a peg and notch assembly and a spring-loaded plunger, additional kinetic energy for propulsion.

  • Patent number: 4582171
    Abstract: A unique drive mechanism for a toy vehicle is disclosed which can be selectively enabled to cause the toy to come to an abrupt halt after a powered run, and which can cause the toy to realistically imitate a "spin out" of a full scale vehicle. The drive train includes a first gear directly rotated by a coiled spring, a second gear coupled in driving engagement with the vehicle's wheels, and a third gear shiftable between an engaged position coupling the first and second gears, and a cleared position wherein the second gear can rotate independently of the first gear. The third gear can be locked in its engaged position by a pivotal, gravity biased locking mechanism. The selective, locked engagement of the first, second and third gears causes the vehicle to come to an abrupt halt after the coil spring has fully unwound at the completion of a powered run.

  • Patent number: 4541815
    Abstract: A toy vehicle has a gear box containing a clock spring which is wound by pushing the vehicle backward. A two part toggle-linkage system connects the gear box to the frame. When the clock spring is wound, the resulting spring bias urges the toggle-linkage system to one over center position which locks the gear box in order to preserve the energy stored in the wound spring. When the toggle-linkage system is pressed near its center, it moves over center to another position, which unlocks the gear box and releases the energy stored in the wound spring in order to propel the vehicle. When the vehicle is next moved backward, the toggle-linkage returns to the locked position which once again locks the gear box.

  • Patent number: 4519789
    Abstract: A combination toy vehicle (10), a jump (14) for the vehicle, a tower (12) holding a swinging hoop (24) having a flame design adjacent the end of the jump, and a landing ramp (16) for the vehicle. The toy vehicle includes a shift lever (110, 110A) to hold the vehicle stationary when a motor in the vehicle is wound, and which upon release, allows the vehicle to move forward over the jump, through the swinging hoop, if in motion, and land on the landing ramp thereby simulating the vehicle leaping through a flaming stunt hoop.

  • Patent number: 4508517
    Abstract: A toy vehicle device includes a pair of interconnected wheeled vehicle housings. The two housings are connected by a member for conjoint movement in parallel to one another and for swinging movement of one vehicle about the other. One of the vehicles includes a propulsion mechanism for propelling both vehicles over a supporting surface. One of the vehicles also includes a mechanism for causing one vehicle to swing about the other vehicle. In one embodiment of the present invention, the mechanism for swinging one vehicle about the other includes a rotatable bar mounted on a first vehicle to periodically contact the supporting surface and pivot the first vehicle with respect thereto so that the first vehicle makes a sharp U-turn. Thus, the second vehicle, connected to the first vehicle by the member, swings in a wider arc about the first vehicle when the first vehicle undergoes a sharp U-turn. This action simulates in an entertaining manner a chase sequence between two vehicles.

  • Patent number: 4493671
    Abstract: A toy vehicle having a spring-operated clockworks motor which is charged by a pumping action, the vehicle having a chassis on whose front and rear ends are supported front and rear wheel axles, and a body resting on the chassis. The front of the body is hinged to the front end of the chassis, a stop being provided whereby the back of the body is liftable with respect to the rear end of the chassis within fixed limits. The clockworks motor, which includes a spiral spring, is mounted on the chassis and is operatively coupled to the rear wheel axle, the motor having a spring-biased crank arm which engages the underside of the body and acts to normally raise the back thereof to its upper limit. The crank arm is operatively coupled to the spiral spring whereby by repeatedly depressing the back of the pivoted body while holding the vehicle to prevent rotation of the rear wheels, the crank is reciprocated to produce a rotary motion to wind the spring and thereby charge the motor.

  • Patent number: 4457099
    Abstract: A toy vehicle has a body, and attached to the body is a chassis which is movably mounted thereon so as to move vertically up and down relative to the chassis. A motor is located within the vehicle and aside from propelling the vehicle forward over a support surface, the motor additionally drives a mechanism which raises and lowers the body relative to the chassis. When the body is raised relative to the chassis, the vehicle is propelled forward over the support surface by the motor; however when the body is lowered to the chassis, the drive connection between the driving wheel of the vehicle and the support surface is severed, inhibiting forward progress of the vehicle. The vehicle performs the above noted functions in a cyclic manner, repeating one after the other.
