Abstract: A portable platform has a first configuration where it may be transported safely over public highways and a second configuration where it is transformed into a display that attracts crowds of visitors at a fair or festival. The platform is elevated above a support surface by a conventional wheel and axle assembly, and is accessible when in its display mode by a stairway. A large structure positioned at one end of the platform is shaped like a beverage bottle, to be promoted and has a hollow interior to house equipment and workers. A door formed in the structure admits personnel, and a window enables the serving of the product being promoted to patrons attracted to the platform by the large structure. Safety rails and a tent-like covering complete the assembly.

Abstract: A children's mini-car includes a three-gear set disposed on a rear axle. The three-gear set, which is driven by the ropes disposed on both sides of the rear axle, is arranged to cooperate with accelerator pedals located on both sides of a front transverse rod to alternatively drive the rear wheels to move the mini-car forward. In addition, a gear shifting lever is used to control the gear set, so as to reverse the direction of movement of the mini-car with the aid of a rear view mirror. Furthermore, a detachable car seat can be removed from the mini-car and a steering wheel can be replaced by a movable pedal, such that the instant mini-car may act as a safe children's sliding car by utilizing an auxiliary brake system located below the steering wheel.

Abstract: A child's pedal-powered vehicle simulating a four wheel drive vehicle includes a body on which there is rotatably supported a pair of rear wheels. Centrally of its front end portion is a drive and steering assembly which is rotatable within the body to effect rotation of a pedal-powered drive wheel at lower end thereof to effect turning motion of the wheel and thereby the vehicle. Mounted on the front end portion of the body outboard of the drive wheel are a pair of outboard front wheels which will readily move vertically on the body to adjust to differences in ground contour while presenting little resistance to turning of the vehicle. In one embodiment, there is included means for limiting the vertical movement so that these wheels will stop upward movement at a point where overturning might occur.
