A stroller includes a foldable frame comprising carbon fiber. The frame is configured to removably connect to at least one of a stroller seat and an infant car seat. The stroller includes a plurality of wheels that support the frame, and a handle coupled to the frame. The stroller may include a suspension system including a leaf having a flexible cantilevered portion fixed at a first end thereof to the stroller frame. The cantilevered portion has a second, free end spaced from the frame. The cantilevered portion is configured to flex about the fixed end. The suspension system includes a damper disposed between the first and second ends of the cantilevered portion and the stroller frame. The damper is configured to compress and expand in response to flexing of the cantilevered portion. A wheel is connected to an underside of said cantilevered portion of the leaf.

A tricycle is provided having a front frame assembly, a rear frame assembly pivotally connected to the front frame assembly, and a release assembly connected to both the front frame assembly and the rear frame assembly to secure the rear frame assembly to the front frame assembly in a use position and alternately in a storage position. The release assembly is moveable to allow for transitioning the rear frame assembly to the storage position from the use position. A foot rest is connected to the tricycle and is also moveable between a use position and a storage position. The tricycle also has a restraint hoop and a canopy, and quick release mechanisms to removably secure the restraint hoop and the canopy to the tricycle.

A stroller is provided with the ability to removably couple and decouple a seat from the stroller as needed. The stroller can include a stroller frame. The stroller can also include one or more front wheels attached to the stroller frame and one or more rear wheels attached to the stroller frame. The stroller can also include a first seat coupled to the stroller frame. The stroller can include first and second seat attachment housings. Each of the seat attachment housings can include a cavity for receiving a corresponding one of the first and second seat attachment adapters. Each of the seat attachment housings can also include a door or cover to prevent access to the respective cavity when not in use. The seat attachment adapters can be coupled to the respective seat attachment housings and a second seat can be coupled to the seat attachment adapters.

A pushchair seat for mounting on a pushchair chassis is comprised of a seating surface and a backrest, wherein the backrest has a distal section and a proximal section which can be rotated relative to the distal section in such a way that the backrest can be folded up from an unfolded backrest usage position into a collapsed backrest storage position.

A child stroller apparatus includes a stroller frame, and a stroller seat supportable by the stroller frame. The stroller seat includes a backrest portion fixedly connected with a first joining part, a seat portion fixedly connected with a second joining part that is pivotally connected with the first joining part, a coupling part pivotally connected with the second joining part and adapted to connect with the stroller frame, a latch movable between a locking position engaged with the coupling part and an unlocking position disengaged from the coupling part, and a linking mechanism configured to movably couple the latch to the first joining part so that a rotation of the backrest portion in a folding direction causes the latch to disengage from the coupling part, and a rotation of the backrest portion in an unfolding direction causes the latch to engage with the coupling part.

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.

The stair-climbing stroller is a baby stroller with retractable front and rear wheels for use on flat travel surfaces and a pair of tracks for use on inclined travel surfaces including, but not limited to, staircases. The front wheels are coupled to a pivoting front wheel support shaft and the rear wheels are coupled to a pivoting rear wheel support shaft. A wheel retract motor located on the underside of the stroller may cause a retraction drive shaft to pivot the front and rear wheel support shafts, retracting the wheels. When the front and rear wheels retract, the stroller may be lowered such that the left and right track rest on the ground. Left and right track motors may then be used to drive the stroller up an inclined travel surface using the tracks.

A child carrying device comprising a frame mounted on a set of wheels or castors to enable the device to be manually conveyed thereon, and a seat mounted on said frame, said device including adjustment means for selectively reconfiguring the device such that it is operable as any one of a stroller, a child back carrier and a high chair.

A collapsible stroller frame assembly which is selectively configurable in an unfolded configuration for carrying a child or infant, and a folded configuration for compact storage or transport in a vehicle, the frame assembly comprising: a front wheel frame with a front wheel assembly; a rear wheel frame with a rear wheel assembly; a lower hinge connecting the front wheel frame to the rear wheel frame in articulated manner, a seat frame hingedly connected to the lower hinge; an upper hinge connected to the seat frame at a position spaced from the lower hinge; a handle frame connected to the upper hinge, a manual release for user actuation; and a mechanical link between the upper and lower hinges; wherein the lower hinge is lockable to hold the seat frame, the front wheel frame and the rear wheel frame in the unfolded configuration, and unlockable to allow relative rotation of the seat frame, the front wheel frame and the rear wheel frame into the folded configuration; and the upper hinge is lockable to hold the handle frame and the seat frame in the unfolded configuration, and unlockable to allow rotation of the handle frame relative to the seat frame into the folded configuration; such that, user actuation of the manual release unlocks the upper hinge for rotation of the handle frame relative to the seat frame, and the mechanical link unlocks the lower hinge in response to a predetermined angular rotation of the handle frame relative to the seat frame.
