An amusement device comprises a lightweight coaster adapted to move by gravitation along a track configuration having portions of varying inclination. The track is supported at its elevated end by an assembly which also serves as a mounting platform, and at a point intermediate its ends by another support structure. Spaced apart, substantially convex parallel rails, on which coaster wheels having a substantially concave circumferential groove therein are adapted to ride, form the track. The coas...

In toy coasters a foot driven steering rear element and a rigid elongated platform for supporting the left foot are provided both the front sections of the rigid base and pivotable rear steering element being provided with wheeled frames having means for regulating the amplitude of the angular displacement of the foot driven steering element.

A roller coaster suitable particularly for young children such as children of pre-school age. A track is provided with a lower front end and a rear upper end while a vehicle is provided for free movement gravitationally down the track from its rear upper end toward its lower front end. A supporting structure supports the rear upper end of the track at the required elevation, this supporting structure also serving to support a releasable holding element which releasably holds a vehicle at the rea...

An improved combination holder and coaster apparatus for receiving a container or vessel which includes first and second thermally insulative, flexible panels joined together by a joint comprised of a stretchable, flexible, adhesive material adapted to return the device to a collapsed coaster configuration. While in receipt of the vessel or container, the device is adapted to an elliptical holder configuration in which the panels are separated by a projected dihedral angle generally between appr...

The coaster includes a wheeled foot platform, the steerable wheel of which is rotatable on a swiveled axle for effecting a steering action. The swiveled axle extends through aligned horizontal slots in vertical axle guides where are spherically curved. Each axle guide has at least one axially extending flange on which rides a bearing element or roller assembled on the axle. The roller and another bearing element assembled on the axle have complementary curved surfaces in sliding bearing engageme...

The present invention discloses a coaster cycle having a front half which works similarly to a bicycle wherein it has handle bars that turn the front wheels. The front wheel turns left and right and also leans in both a left and right direction. The front wheel leans left to right and is connected to the rear wheels by a frame having multiple pivotal couplings so that the rear wheels lean left or right with exactly the same angle as the front wheels. The leaning of the front and rear wheels in c...

A realistic roller coaster simulator is disclosed having one or more passenger seats equipped with a safety harness and mounted for 360 degree rotational movement along at least two axes for simulating the motion of a roller coaster. A controller is provided for controlling and coordinating the motion of the simulator with a simulation controller which generates to the passenger synchronized audio and visual effects which would be experienced by a passenger on a roller coaster of a predetermined...

A roller coaster toy includes a set of cars mounted on a track. Each car has at least one pair of movable side wheel assemblies mounted for movement towards and away from opposite sides of a respective car to enable the cars to be easily placed on, or removed from, the track. A drive car has movable drive wheels for affirmatively engaging the track no matter the degree of curvature of the track.

A coaster brake hub including a housing having a generally cylindrical passage therethrough, an axle, a drive shaft, a drive cone, and a brake mounted within the passage. The passage has a surrounding wall. The hub also includes a clutch disposed within the passage mounted to the axle. The clutch is moveable between a first position and a second position. In the first position, the clutch rotatably interconnects the drive shaft with the brake such that rotation of the drive shaft in a first dire...

A tire assembly for a wheeled vehicle has a ring-shaped integrally formed outer tire member made of relatively hard and relatively rigid material, and a ring-shaped integrally formed inner tire member. The inner tire member is made of a resilient material that is essentially incompressible but rather easily deformable, and has protuberances and recesses formed in its circumferential surface to allow for both radial compression and lateral expansion of its material, thereby ensuring resilient sup...
