A wheeled carrier device such as a baby stroller, golf cart, child carrier, or general carrier or cargo cart, comprising a bottom frame with at least two rear wheels and at least one front wheel, and may include a movably mounted upper carrier frame with a selectively removable, adjustable and/or reversible carrying element which may include child seating, with a unique wheel folding mechanism that interconnects all the wheels, so that simple movement of a wheel folding grasp synchronously moves all the wheels between the operative, rolling position and their stowed fold flat positions parallel with the bottom frame, with the wheel folding mechanism operable independently of collapsing movement of an optional upper carrier frame which also folds flat and parallel with the bottom frame.
A foldable wheeled carrier device comprising a bottom frame forming a perimeter and a side elevational profile, at least two rear wheels and at least one front wheel movably mounted to the bottom frame, each wheel including a central axis of rotation, and having an operative and stowed position, an upper carrier frame movably mounted to the bottom frame including a carrying element, and a dual action wheel folding apparatus interconnected to each of the wheels which synchronously moves the at least two rear wheels and the at least one front wheel between the operative and stowed positions, comprising a movable push-pull grasp separate from the carrier bottom frame and the wheels, interconnected to the bottom frame and to the at least one front wheel by a front wheel transverse mounting rod, and the movement of the grasp further translates motion through a rear wheel transverse connector to the rear wheels through tie rods incorporated in the bottom frame, and in a first, operative position the grasp is moved inwards, which positions each of the rear wheels and the at least one front wheel orthogonally to the bottom frame providing rolling support, and in a second, stowed position the grasp is moved outwards sweeping each rear wheel and the at least one front wheel through an angle positioning each wheel parallel with, and closely adjacent to the bottom frame underside, with each wheel's axis of rotation within the perimeter and side elevational profile of the bottom cart frame.
A foldable wheeled carrier device comprising a bottom frame including a least two substantially parallel side portions with a front and rear, joined at least near to the front by a dual action grasp, and a front and rear wheel transverse mounting connector portion, forming a bottom frame periphery, and a side elevational profile, at least a pair of rear wheels, each of the pair mounted near the rear of the bottom frame side portions, and at least one front wheel also movably mounted to the bottom frame front transverse mounting connector portion, each wheel including a central axis of rotation and having an operative position wherein all wheels are positioned orthogonally to the bottom frame providing rolling support and a stowed position wherein all wheels are substantially parallel with the bottom frame and within the bottom frame's side elevational profile, an upper carrier portion movably mounted to the bottom frame including a carrying element, and a wheel folding apparatus interconnected to each of the wheels which synchronously moves the at least two rear wheels and the at least one front wheel between the operative and stowed positions, comprising a manually movable grasp interconnected to the bottom frame and to the at least one front wheel by a front wheel pivoting transverse rod connected to the at least one front wheel, and by a rear wheel transverse connector controlling a pair of tie rods interconnected to the at least two rear wheels, and push-pull movement of the dual action grasp translates motion to the at least one front wheel and to the rear wheels to move them between the operative and stowed positions.
A foldable wheeled carrier device comprising a bottom frame including a least two substantially parallel side portions with a front and rear, joined at least near to the front by a dual action grasp and a front and rear wheel transverse mounting connector portion, forming a bottom frame perimeter and a side elevational profile, at least a pair of rear wheels, each of the pair mounted near the rear of the bottom frame side portions, and at least one front wheel movably mounted to the bottom frame front wheel transverse mounting connector portion, each wheel including a central axis of rotation, and an operative and stowed position, and a wheel folding apparatus interconnected to each of the wheels which synchronously moves the at least two rear wheels and the at least one front wheel between the operative and stowed positions, comprising a manually movable grasp interconnected to the bottom frame and to the at least one front wheel by a pivoting transverse rod connected to the at least one front wheel, and by a rear wheel transverse connector controlling a pair of tie rods interconnected to the at least two rear wheels, and push-pull movement of the dual action grasp translates motion to the at least one front wheel and to the rear wheels to move them between the operative and stowed positions.
