Various embodiments of a collapsible stroller configured to form at least a compact collapsed configuration are described. In some embodiments, the collapsible stroller includes a foldable frame assembly including a top frame pivotably coupled to a bottom frame such that the top frame is allowed to pivot along a longitudinal plane of the foldable frame assembly. The foldable frame assembly can include first strut assemblies pivotably coupled to the bottom frame at respective angled joints. The angled joints can each include a first axis of rotation that is angled relative to the longitudinal plane such that the strut assemblies pivot towards the longitudinal plane as the top frame pivots towards the bottom frame for forming the collapsed configuration. In some embodiments, the foldable frame assembly further includes a suspension system that also can pivot towards the longitudinal plane when the foldable frame assembly forms the collapsed configuration.

A child stroller apparatus includes a rear leg frame having a first side segment fixedly connected with a first coupling part, a front leg frame having a second side segment fixedly connected with a second coupling part, a handle frame having a third side segment fixedly connected with a third coupling part, the second and third coupling parts being respectively connected pivotally with the first coupling part, a front guard pivotally connected with the first coupling part, a first linking assembly rotationally coupling the second side segment with the third side segment, and a second linking assembly rotationally coupling the front guard with the second side segment. The front leg frame, the handle frame and the front guard are linked and rotatable relative to the rear leg frame during folding and unfolding of the child stroller apparatus.

A stroller frame includes a seat pan, an operating handle movably coupled to the seat pan, and two opposite foldable side frame units each including a front leg, a handle rod, a rear leg that has a top end pivotally connected to the handle rod, a bottom leg that has a lower end pivotally connected to the rear leg, and a sliding basket tube that is movably coupled to said seat pan and slidably connected to said rear leg. To unfold the stroller frame, said operating handle is pushed downward to drive said seat pan to pivot downward so that an angle between said front leg and said bottom leg of each of said side frame units increases until said stroller frame is converted from a folded state to an unfolded state.

A carrier device and a stowing method are disclosed. The rear wheel frame is disposed on the front wheel frame. The front wheel is disposed on a first end of the front wheel frame. The rear wheels are disposed on two ends of the rear wheel frame. The upper frame is disposed on a second end of the front wheel frame. The upper stoppers are disposed on the handle frame linkage, the upper frame or the handle frame. The carrier device has a stowing state including a stowing position, in the stowing position, a plane formed by the front wheel and a plane formed by one of the rear wheels are substantially perpendicular to each other, and the upper stoppers are disposed on two sides of the plane formed by the front wheel respectively. This disclosure has the advantages of easy folding and stowing.

A baby stroller for transporting an infant at speeds faster than normal walking is disclosed. This baby stroller can be folded to make it easier to stow and transport. The folding mechanism, a unique feature of the design is directed toward compactness, ease of use, reliability, and reduction in manufacturing costs.

A wheeled cart includes a number of unique methods to synchronously stow all of the rear wheels of a fold flat, compact wheeled cart device without removing any of the wheels themselves and the innovations are applicable to cargo carriers, golf bag carts, trolleys, baby strollers, and other devices for moving cargo. In alternative designs, the folding motion of either the forward wheel frame, or the swiveling motion of the rear wheel frame, or both, synchronously setup or stow the cart's at least two rear wheels to achieve an ultra-thin stowed profile, orienting all the cart's wheels in a co-planar stowed relationship, closely parallel with all other parts.

A foldable personal such as a tricycle which can be convertible into a stroller, is configured for accommodating a child therein and for preventing, when desired, the child from being able to steer the vehicle, vehicle having an operational state and a storage state, in which it can take an extremely compact form. The vehicle has a longitudinal axis lying in its vertical plane of symmetry and having a horizontal reference plane perpendicular to the plane of symmetry, and it takes its compact form in the storage state both in the direction along its longitudinal axis and in the directions perpendicular to this axis both along the plane of symmetry and perpendicular to the plane of symmetry.

A child stroller frame includes a first and a second frame portion, a pivoting part and a linkage. The second frame portion has a front end and a rear end, the front end of the second frame portion being pivotally connected with the first frame portion. The pivoting part has one end fixedly connected with a rear wheel support member and another end pivotally connected with the rear end of the second frame portion. The linkage movably couples the first frame portion to the pivoting part, and has an intermediate portion pivotally connected with the second frame portion, whereby the first frame portion and the rear wheel support member are movably linked for folding in a concurrent manner toward the second frame portion.

A foldable baby stroller movable between unfolded and folded states. The stroller includes a frame, a front wheel assembly on a front portion of the frame including a front wheel, a rear wheel assembly on a rear portion of the frame including two rear wheels, and a seat assembly on an upper portion of the frame. The frame includes a head tube; at least one beam having a first end pivotally connected to the head tube; at least one joint, to which a second end of the beam is pivotally connected; and at least two rear fork rods having a first end pivotally connected to the joint and a second end connected to the rear wheel assembly. Parts of the foldable baby stroller do not need to be detached during folding, thereby implementing “one-click” folding, and making the operation more convenient and efficient.
