A harness assembly for towing a carriage and or trailer is disclosed. An example harness assembly includes a first frame for connecting to the carriage or trailer, and a second frame connected at a first end portion to the first frame. The second frame also has a second end portion for connecting to a user. At least one rotatable member of the second frame provides side-to-side rotation of up to about 180 degrees between the user and the carriage or trailer. In an example, the first frame is rotatably attached to the second frame to provide for up-and-down movement between the first frame and the second frame, thereby adjusting to different height users and dissipating at least some of the motion from the user before the motion from the user reaches the carriage or trailer.

A carriage has a carriage body having a loading platform for bearing a load and a plurality of wheels rotatably retained to the loading platform, an operation handle connected to the carriage body and grasped by a user operating the carriage, a sensor for measuring information related to a force applied to the operation handle, and a driving device for outputting a driving force based on a result of detection by the sensor to any of the plurality of wheels.

A hook attachment for an IV stand. The attachment has hooks attached to at least one longitudinally extending portion. The hooks are configured to position bags such that their labels are each visible from the same side of the hook attachment. The hooks may include first and second hooks coupled to first and second longitudinally extending portions, respectively. The first and second hooks are configured to have first and second bags, respectively, hung therefrom. The first and second longitudinally extending portions are sufficiently spaced apart vertically to allow the labels of the first and second bags to be visible. The hooks may include front and rear hooks connected to a longitudinally extending body portion. The front and rear hooks have first and second portions, respectively, whereat front and rear bags, respectively, are positioned when hung therefrom. The first portions are below the second portions.

Exemplary embodiments of an expedition cart are provided. The expedition cart includes a chassis configured and dimensioned to support a load. The expedition cart includes first and second gusset plates attached to the chassis. Each of the first and second gusset plates includes a central body portion and curved fastening edges on either side of the central body portion. The curved fastening edges can be configured and dimensioned to mate against at least a portion of the chassis. Exemplary embodiments of an expedition cart are also provided that include first and second hubs engaged with the chassis, the first and second hubs defining either a single part or a two part design.

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 method of assisting in the mobility of a wheelbarrow includes the steps of coupling a first coupling arm and a second coupling arm of an assist device to a portion of a top edge of the wheelbarrow; orienting a first flexible connector and a second flexible connector underneath the wheelbarrow such that the first flexible connector and the second flexible connector are contactable with a shell of the wheelbarrow; grasping a handle coupled to the first flexible connector and the second flexible connector by an assistant; grasping handles of the wheelbarrow by an operator; applying a first force from the operator to the handles, elevating legs of the wheelbarrow; providing a second force by the assistant on the handle; and maintaining the first force while the second force is provided.

A multi-function baby carriage comprising: base frames; a back frame installed at rear ends of the base frames to switch between a vertical position and a horizontal position and formed with a U-shaped hanger at its top for being suspended from a user's neck or a headrest of a car; a seat on the base frames to accommodate a baby; and wheel means below the base frames, wherein said wheel means include front and rear wheels, front and rear connectors, a front cross member connecting the front connectors, a rear cross member connecting the rear connectors, each of said front and rear connectors having an end rotatably connected to one of the front and rear wheels and the other end connected to one of axes, wherein said shaft is provided with a ball member, so that when the front or rear wheels are folded or unfolded, said shaft causes the front and rear wheels to move at the same time and said ball member passes through a ball holding member in a forward or backward direction to make said ball member to stop at a front or rear end of said ball holding member, to thereby maintain a folding state or an unfolding state of the front and rear wheels, and wherein said ball holding member has a cylindrical form that can expand in a radial-outward direction and retract in a radial-inward direction.

A base having legs supported on wheels. A second leg may be positioned between first and third legs and the first leg may be positioned between the second leg and a fourth leg. A first gap is positioned between the second and third legs, and a second gap is positioned between the fourth and first legs. The first and second gaps are configured to at least partially receive a user's first and second feet, respectively. A keyway with a bridge may be defined between the first and second legs. A key that may be formed in a fifth leg is removably receivable inside a like keyway of a like base to thereby interlock the bases together so that they are moveable as a unit. An end portion of the key is positionable underneath a like bridge of the like keyway such that the like bridge limits upward movement of the key.
