Abstract: Exemplary embodiments are provided of wheelchairs. In an exemplary embodiment, a wheelchair generally includes a seat and a carriage coupled to the seat. The carriage and seat are laterally moveable together in a transverse direction relative to a forward direction of the wheelchair. In use, lateral movement of the carriage and seat outside of a wheelbase of the wheelchair enables lateral transfer of a patient to and/or from the wheelchair.

Abstract: Various exemplary embodiments are provided of wheeled shovels. In one exemplary embodiment, a wheeled shovel generally includes a wheel assembly having an axle and a wheel. The wheeled shovel also includes a frame having an upper portion and a lower portion. The frame may be disposed relative to the axle such that the axle is operable as a fulcrum about which the frame may pivot. A handle may be disposed at about the upper portion of the frame. A shovel blade may be disposed at about the lower portion of the frame. The wheel assembly, frame, handle, and shovel blade may be cooperatively configured so as to enable the wheeled shovel to throw a load of material generally upwardly and forwardly away from the shovel blade in response to a sufficient force applied to the handle for pivoting the frame relative to the axle with a recoil generated through the fulcrum at the axle.

Abstract: Various exemplary embodiments are provided of wheel assemblies and tires. In one exemplary embodiment, a wheel assembly generally includes first and second wheel pieces attachable to each other. The first and second wheel pieces may include respective first and second rim portions. Each of the first and second rim portions may include an arced portion that defines only a portion of a circumference of a rim, such that the arced portions collectively define the circumference of the rim when the first and second wheel pieces are attached. The first and second wheel pieces may be slidably engagable in a first axial direction that is substantially parallel to a rotational axis of the wheel assembly. The first and second wheel pieces may be slidably disengagable in a second axial direction that is generally opposite the first axial direction.

Abstract: Various exemplary embodiments are provided of hinge apparatus, which may be used, for example, to hingedly connect upper and lower frame members of a device or tool. In one embodiment of a hinge apparatus, first and second linking members each include a base portion, sidewalls, and flange portions. The flange portions define sets of openings configured to receive a portion of a first connector, for selectively adjusting the angular orientation of the upper frame member relative to the lower frame member in an open, ready-for-use configuration. The linking members include connector openings configured to receive a portion of a second connector. When the first connector is not engaged with any set of openings, the upper frame member is pivotably movable relative to the lower frame member about the second connector to a closed, collapsed configuration in which the upper frame member is alongside the lower frame member.

Abstract: An apparatus comprising a shovel disposed on a relatively large wheel and a method of using the apparatus for handling a load of material. The apparatus involves a shovel having a handle formed at the end of an elongate yoke, the yoke being mounted, at its middle portion, onto the axle of a relatively large wheel for the purpose of picking up of a load, transporting it to a location, and propelling the load overboard with a quick arm/body motion on the part of a person operating the handle. The substantially waist-high wheel is adapted to receive the body force of an operator as an effective leverage through the handle and cause a recoil action from the wheel to enhance the throwing power of the apparatus of the invention, comprising the shovel, the wheel and the yoke as the driving member.
