A tricycle may be operable between a first mode of operation steerable by a tricycle rider, and a second mode of operation steerable by an individual pushing the tricycle. In both such first and second modes, the frame of the tricycle is configured to rotatably support the rear wheels and configured to support the head tube at a distance from the rear wheels such that a distance between the head tube and rear wheels need not necessarily be changed even when the front wheel axis location is changed from one mode to another.

The invention relates to a child carrying device that includes a stroller configuration and a wagon configuration. The child carrying device comprises a support frame that may be rotated from an angled orientation in the stroller configuration to a substantially horizontal position in the wagon configuration.

An adjustable stroller having a main carriage and a handle bar assembly, wherein the handle bar assembly is configured to convert between push and pull configurations to enable a user to either push or pull the stroller. More specifically, the adjustable stroller includes the main carriage, pulling rails comprised of handle bar tubes and telescoping rail tubes, two rear wheels attached to the main carriage and the proximal ends of the pulling rails via wheel hubs, a cross bar and center handle configured to host conversion and brake mechanism controls, and a third, front wheel to offer stability and balance. The handle bar assembly in dudes the pulling rails and the cross bar and center handle. In the pull configuration, the distal ends of the pulling rails can attach to an adjustable running belt that a user can wear around the user's waist.

A child transport carrier includes an upper frame member having a forward end and a rear end and a rear frame coupled to the upper frame member. The rear frame includes a lower rear frame member, an upper rear frame member having an upper end fixedly coupled to the rear end of the upper frame member, and a first joint assembly coupling the lower rear frame member and the upper rear frame member. The rear frame is configured to fold between an unfolded in-use position and a folded storage position. The upper frame member and the upper rear frame member are fixed relative to each other. The first joint assembly is disposed longitudinally rearward of the forward end of the upper frame member and longitudinally forward of the rear end of the upper frame member in the unfolded in-use position.

Disclosed is a bike trailer having a main frame and a seat structure. The main frame defines an accommodating space for a passenger or load to be transported. The seat structure is transferable between an operational state in which the seat structure forms a seating area for the passenger, and a stowed state in which the seat structure is folded away thereby allowing the transport of loads other than passengers. The seat structure comprises a backrest portion with a seating side for at least partially contacting the back of a passenger. The backrest portion is accommodatable in the bike trailer such that at least the seating side of the backrest portion is protected against contact with loads to be carried when the seat structure is in the stowed state.

A child transport carrier includes a lower frame member having a forward end and a rear end, an upper frame member having a forward end and a rear end, and a rear frame coupling the lower frame member to the upper frame member. The rear frame includes a lower rear frame member having a lower end coupled to the rear end of the lower frame member and an upper rear frame member having an upper end coupled to the rear end of the upper frame member. A first joint assembly couples the lower rear frame member and the upper rear frame member. The rear frame is configured to fold between an unfolded in-use position and a folded storage position. An exterior angle formed by the lower rear frame member and the upper rear frame member is less than 180 degrees in the unfolded in-use position.

A multi-function stroller may comprise a lower chassis shell and an upper occupant shell connected by a quick release pivot joint that provides occupant accommodation that is secure and comfortable. In addition, the structural architecture is designed to allow safe adaptations to the axle configuration. Through flexible suspension arm mounting the suspension-hub-wheel/tire assembly can be quickly assembled/disassembled to provide alternative usage axle layouts. An ergonomic handle assembly may be coupled with the structure for pushing, pulling, towing, carrying, etc. When disassembled, the multi-function stroller can be folded into a compact storage mode. Thus, non-compromised performance, versatility, and usage functionality can be readily achieved and accomplished in a safe manner.

A tricycle may be operable between a first mode of operation steerable by a tricycle rider, and a second mode of operation steerable by an individual pushing the tricycle. A rider handle, in the first mode, may be configured to be rotationally coupled with the stem in a manner permitting a tricycle rider to exert forces on the rider handle and thereby turn the fork, and the rider handle in the second mode, being configured to be rotationally uncoupled from the stem, preventing forces on the rider handle from turning the fork. At least one rotation restrictor may be included for preventing the front wheel from turning to a position where the front wheel axis leads the fork axis, and for maintaining the front wheel axis in a position trailing the fork axis both when the tricycle is propelled by a tricycle rider in the first mode and when the tricycle is pushed from behind in the second mode.

A tricycle may be operable between a first mode of operation steerable by a tricycle rider, and a second mode of operation steerable by an individual pushing the tricycle. In both such first and second modes, the frame of the tricycle is configured to rotatably support the rear wheels and configured to support the head tube at a distance from the rear wheels such that a distance between the head tube and rear wheels need not necessarily be changed even when the front wheel axis location is changed from one mode to another.
