  • Patent number: 11571631
    Abstract: A toy vehicle playset comprises a stunt loop apparatus. The stunt loop apparatus has a support, a partial loop portion coupled to the support, and an arcuate portion rotatably coupled to the support. The partial loop portion has an opening and the arcuate portion is configured to rotate between an inlet position and an outlet position within the opening. By rotating the arcuate portion from the inlet position to the outlet position, a continuous pathway is formed that allows a toy vehicle to sequentially travel along the arcuate portion in the inlet position, the partial loop portion, and then the arcuate portion in the outlet position.

  • Patent number: 10065125
    Abstract: A 3-dimensional high-speed track car toy comprises a track body and a toy car. Straight tracks, curved tracks, centripetal tracks and centrifugal tracks are assembled to form a 3-dimensional closed track. The track body stands on the ground fixedly through support rods and support seats. The track body is paved with a track along which the toy car runs. Components of the track body have fastener-containing groove structures to fix an iron axis onto the track. The toy car is placed on the track body. The track is equipped with an iron axis. The bottom of the toy car is equipped with magnets. Thereby, a sufficient attractive force is generated to overcome gravity of the toy car. Therefore, the toy car can run on the track disposed on a ceiling or a vertical wall. Thus, the user can enjoy more amusement from playing the present invention.

  • Patent number: 7794301
    Abstract: A toy vehicle trackset utilizes a pair of closed track loops each having a lower end and a raised end. The raised ends of the loops are supported by a raised support having a spring-loaded dinosaur launcher within which a flying dinosaur is supported. A target is coupled to the launcher and positioned in alignment with a pair of launch ramps extending from each of the pathways through a center lap counter which is shaped to simulate a volcano. Within the lap counter, a diverter is supported to switch a moving toy vehicle from its normal loop path to the target directed ramp once the toy vehicle has completed a predetermined number of laps upon the loop by one player. A dual loop hand-operated toy vehicle booster is supported at the lower end return path of each of the loops. The child user is able to crank a hand crank to initiate a manual boost of a toy vehicle. Proper timing of the hand crank is essential to impart maximum boost to a toy vehicle and impart rapid vehicle movement.

    Abstract: A collision course including at least two vertically stacked looping track sections, each looping track section starts at a beginning area that connects to an upwardly extending curved section that peaks at an apex and then travels along a downwardly extending curved section. In order to stack the looping track sections vertically each looping track section is unsymmetrical. The downwardly extending curved sections feed into the beginning areas of the succeeding looping track section, and the downwardly extending curved section of the last (or third) looping track section feeds into the beginning area of the first looping track section. Each looping track section further intersects with another looping track section to define junctions. Gaps formed in each intersecting track section permit a vehicle to travel through the intersection unobstructively.

In the preferred embodiment, the wheeled vehicle has freely mounted wheels for rotation, and an upwardly extending rod which engages a lift mechanism flange. The lift mechanism raises the vehicle to a height at which gravitational force then imparts movement to the vehicle around a continuous trackway. The vehicle remains positioned on the trackway due to a trackway rail positioned between the freely mounted wheels of the vehicle. The trackway includes four different track sections which impart different movements to the vehicle as the vehicle moves along the trackway. In one track section, for example, the trackway imparts a loop-to-loop movement to the vehicle.

  • Patent number: 4165695
    Abstract: A roller-coaster track includes a vertical loop and terminates in two steep rises, with a loading and unloading station disposed along a horizontal stretch of track between the loop and the lower of the two rises. An endless belt underneath that horizontal stretch entrains a carriage which, when moving along an upper run of that belt, accelerates a passenger train at the station from standstill to a velocity sufficient to let that train pass through the loop in one direction, ascend the higher rise, descend that rise and pass once more through the loop in the opposite direction before ascending and descending the lower rise, eventually coming to rest at the station. The accelerating force is derived, at the start of the ride, from stored potential or kinetic energy such as that of a weight dropping inside a guide tube or a flywheel intermittently coupled with the belt.
