The stair-climbing wheeled carrier has a U-shaped frame defined by a pair of elongated parallel handles and a crossbeam extending between the ends of the handles. Each handle has an axle mount depending therefrom having a star wheel or spider wheel mounted thereon. A dual shaft worm drive motor is mounted on the frame, the shafts driving chain drives connected to the wheels. A throttle extends from one of the handles, and controls leaf springs that operate switches for actuating the reversible motor and returning the throttle to neutral when released. A payload is attached to brackets mounted on the handles. The payload may be a seat for a person needing assistance attending/descending stairs, or a basket for carrying packages or other items upstairs. In use, an assistant uses the handles to support the frame while operating the motor to activate the wheels for climbing stairs.

A pull-behind carriage has an auxiliary wheel mounted on a reconfigurable drawbar. When the pull-behind carriage is converted to a push carriage, the drawbar is folded so that the auxiliary wheel is positioned on the ground to act as an extra, supporting wheel. Joints in the drawbar are palm operated and can be rotated without continuing to hold the joint. The drawbar may also serve to move the axle of the main wheels backwards when the carriage is converted from the pull-behind mode to the push mode.

An apparatus and method for towing a load behind a person is disclosed which reduces or dampens the effect of human movement on the load and vice versa. Further, the apparatus and method reduce or dampen the impact and vibrations resulting from traveling over a surface. In one embodiment, the apparatus and method is comprised of a harness for a person to wear, a carriage, and a bow connecting the harness and the carriage.

A device for transporting children. The transportation device includes a base and sidewalls extending therefrom, forming an interior volume. Wheels extend from a lower side of the base and a foldable seat is affixed to at least one sidewall. A pair of doors are hingedly attached to opposing sidewalls, which allow a child ingress and egress from the transportation device. The folding seat allows the transportation device to include an increased capacity to hold objects when not in use by the child.

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 harness for pulling a carriage by a person is attached to a pulling assembly, which includes a rigid drawbar coupled to the carriage and a cantilevered member coupled to the forward end of the drawbar and to the harness. The cantilevered member partially isolates cyclical motion of the person from the drawbar, and may be a spring, a sprung rigid member or a rigid member controlled by an electronic servo.
