Title:
FOLD FLAT CHILD AND CARGO CARRIER TRAILERS AND STOLLERS, INCLUDING PIVOTING WHEEL AXLES
Document Type and Number:
WIPO Patent Application WO2004071841
Kind Code:
A3
Abstract:
Fold flat wheeled child and cargo carriers adopting pivoting, stowable wheel axles are disclosed, of the general type which may be trailed behind other devices by a stowable and removable tow bar. The carriers may be trailed behind other devices, or are convertible to strollers or push/pull style devices. The pivoting wheel axles in various embodiments, include simple manually manipulable methods to latch each wheel in the operative or stowed flat positions, which effectively allows the device to fold to an ultra thin profile without any wheel being detached, and the wheel axles and tires, in the stowed positions also secondarily serve to retain the various folding parts in their stowed positions within the device side elevational profile. In the child trailer and cargo carriers, the tow bar, carrier walls and associated parts all fold flat to the device frame, along with the wheel axles and tires. Associated innovations include stowable push/pull handles, fold flat forward wheel axle structures, and details of the internal components of the pivoting wheel casing and its support.
