A one-hand operated wheel orientation structure and a child carrier including the same. The one-hand operated wheel orientation structure includes an orientation operating portion arranged on the frame of a child carrier; a plurality of wheel orientation assemblies to lock or unlock the orientation of the corresponding wheel set; and a plurality of traction devices arranged corresponding to the wheel orientation assemblies one by one, one end of each of the traction devices is connected to the orientation operating portion, and the other end of each of the traction devices is connected to each of the wheel orientation assemblies, respectively. The actuation action or release action of the orientation operating portion is transferred to the wheel orientation assemblies through the traction devices, respectively, to unlock or lock the orientation of the corresponding wheel set.

The invention relates to a children's vehicle having a vehicle body (10) on which are mounted a front wheel (31) and at least one rear wheel (32), a steering sub-assembly (20) having a steering column (21) linked to the front wheel (31) and a handlebar (22), a seat (41) configured to accommodate a child, a safety element (50) configured to surround at least a first area of the child's body when it is installed on the seat (41), the handlebar (22) being removable between: a first configuration in which the handlebar (22) is remote from the safety element (50), and a second configuration in which the handlebar (22) is close to the safety element (50) and surrounds a second area of the child's body.

A three-wheeled all-terrain vehicle or push chair utilizes an innovative front wheel mount, employing a side-mounted caster mechanism, for improving its pushability and steerability. Because of this approach, lifting is not required to steer the chair, and any size or type and width of wheel can be used. As a result, the invention provides a new class of all-terrain product for the disabled adult market and a rugged, truly off-road runner/jogger/hiker stroller for the young child market.

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 transportation apparatus reconfigurable between at least two modes of operation. Each mode of operation comprises a mode of transport. A first mode of operation comprises a stroller, push-chair or perambulation (pram) mode. A second mode comprises a velocipede mode, such as a tricycle, bicycle and/or quadricycle mode.

A vehicle for an infant having a vehicle body (10) having a front end (11) and a rear end (12), a front steering unit (20) mounted on the front end (11) and including a steering column (21) on which a front wheel (31) and a handlebar (22) are mounted, a seat (41) mounted between the front end (11) and the rear end (12), a first rear wheel (321) connected to the vehicle (10) body via a first wheel carrier (171) and a second rear wheel (322) connected to the vehicle body (10) via a second wheel carrier (172), the first and the second wheel carriers (171, 172) being rotatably mounted on the rear end (12) between a compact configuration and a deployed configuration, the first and the second wheel carriers (171, 172) being movable between the two configurations independently of each other.

A ridable kart can have a body that supports a front wheel and movable rear wheels. The kart can include a motor that supports and drives the rear wheels. The motor and rear wheels are configured to tilt and rotate relative to the body of the kart. The body of the kart includes a concave space in which the front and rear wheels are positioned so that they are at least partially concealed by the body when viewed from the side of the kart.

A foldable tricycle is provided and has a frame having a first end and a second end, a seat connected to the frame, a front wheel adjacent the first end of the tricycle, and a rear wheel adjacent the second end of the tricycle. A head tube housing is provided adjacent the first end of the main frame, and a fork is provided adjacent the first end of the tricycle. The front wheel is rotatedly secured to the fork. A stem extends from the fork and supports a handlebar, wherein a portion of the head tube housing is slidingly connected to the stem, and wherein the tricycle can be manipulated between a use position and a folded position by sliding a portion of the head tube toward the handlebar.

Examples of the present disclosure are related to systems and methods for an attachment for a stroller, walker, wheelchair, ambulation device, or other transportation device. More particularly, embodiments relate to a wheeled board that is configured to be coupled to an axle and a support of the transportation device, wherein a lower clamp connected to the axle is positioned orthogonal to an upper clamp coupled to the support of the transportation device.

A wheeled platform has a base, a plurality of wheels, and a power supply. A connector extends from the wheeled platform. A motor assembly has at least one motor mounted on the connector to couple with a stroller. A controller assembly steers the stroller. The base includes an upper surface for supporting an operator. The base forms a wheel assembly for holding the wheels. The power supply sends power to the motor assembly through the control assembly to drive the stroller.
