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 stroller and foldable frame assembly for a stroller includes a locking mechanism adjustable between a locked position and an unlocked position. The locking mechanism is configured to releasably lock the foldable frame assembly in its use configuration and/or storage configuration by releasably and internally locking at least one of a respective swivel joint assembly of the frame assembly. The locking mechanism includes an actuation element configured to adjust the locking mechanism between the unlocked and the locked position that is arranged spaced apart transversely to a swivel axis of the respective at least one internally lockable swivel joint.

A child stroller frame includes a first frame portion including a handle frame segment and a front leg segment pivotally connected with each other, a second frame portion pivotally connected with the front leg segment, a pivoting part having one end fixedly connected with a wheel support member and another end pivotally connected with the second frame portion, and a linkage movably coupling the first frame portion to the pivoting part. The linkage has a first end pivotally connected with the front leg segment, a second end pivotally connected with the pivoting part, and an intermediate portion between the first end and the second end that is pivotally connected with the second frame portion, whereby the first frame portion and the wheel support member are movably linked for folding in a concurrent manner toward the second frame portion.

A stroller having a frame, a seat on the frame for receiving a child and a heating/cooling system operably coupled to the seat. The heating/cooling system includes a single heating and cooling element proximate the seat. A reversible compressor is operably coupled to the single heating and cooling element. A first coil operably coupled to the compressor. A reversible expansion valve is operably coupled to the first coil. The reversible expansion valve is operably coupled to the single heating and cooling element. A refrigerant circulates through the single heating and cooling element, reversible compressor, first coil and reversible expansion valve. The heating/cooling system provides a first operating configuration for cooling the seat by having the refrigerant within the single heating and cooling element absorb heat, and a second operating configuration for heating the seat by having the refrigerant within the single heating and cooling element dissipate heat.

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.

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.

The locking mechanism is configured to releasably lock the foldable frame assembly in its use configuration and/or storage configuration by releasably and internally locking at least one of a respective swivel joint assembly of the frame assembly. The locking mechanism includes an actuation element configured to adjust the locking mechanism between the unlocked and the locked position that is arranged spaced apart transversely to a swivel axis of the respective at least one internally lockable swivel joint.

A stroller assembly may be configurable as an assembled stroller having selected components defining one of a plurality of potential stroller configurations. The stroller assembly may include a plurality of constituent assemblies. Each of the constituent assemblies may include a plurality of selectable components that, when selected and combined into the assembled stroller, define a corresponding expression of the stroller assembly.

An example baby carrier includes an enclosure, a seat configured to receive a baby, a back frame, and a first support frame. The first support frame includes an extendable arm having a handle, a first hinged leg, and a first wheel mounted to the first leg. The baby carrier is configured to reversibly transition between at least a stowed mode, a stroller mode, and a carrier mode.
