A system for adapting a hub for coupling the hub to a wheel where the wheel is not sized for attachment to the hub. The system includes and an adaptor or wheel adaptor for coupling the hub to the wheel. The wheel adaptor includes a body, a first set of holes, a second set of holes, and a third set of holes.

The wheel holding member for a vehicle has a rod-like shape, and includes: a thread portion, which is formed on an end portion on a proximal end side, and has a male thread threadedly engageable with a hub bolt hole formed in a wheel hub; a holding portion, which protrudes toward a distal end side with respect to the thread portion, and has no thread on an outer periphery thereof; and a tool insertion hole, which is exposed from an end surface on the proximal end side, and to which a tool for rotating the wheel holding member is insertable. A bottom surface of the tool insertion hole is located on the distal end side with respect to an end of the thread portion on the distal end side.

A noncorrosive, water-impermeable gasket is used between a wheel rim and a hub assembly so that they do not corrode together making their separation difficult or impossible. The gasket includes a gasket flange with a gasket bolt pattern that is alignable with a hub bolt pattern of the hub assembly and a rim bolt pattern of the wheel rim.

A wheel spacer disc for motor vehicles having a plurality of wheel bolt openings, a rim centering element for centering a rim relative to the wheel spacer disc, and a wheel hub centering element for centering the wheel spacer disc relative to a wheel hub.

The plurality of wheel bolt openings are designed in each case as stepped openings for the respective partial reception of shaft nuts, wherein a section of the stepped openings having a greater diameter is arranged on a side of the wheel spacer disc on which the rim centering element is arranged.

A wheel adapter to convert a storage container to a wheeled storage container is provided. The wheel adapter comprises a mounting bracket attachable to the storage container. The mounting bracket comprises a first leg configured to engage a bottom surface of the storage container, and a second leg configured to engage a side surface of the storage container. The second leg comprises a wheel coupling. The wheel adapter also includes a wheel rotatably connected to the wheel coupling. The wheel is constructed and arranged for rotation about an axis to provide rolling support of the storage container on the ground.

A tool for mounting a motor-vehicle wheel on a wheel hub includes a tubular body having a coupling portion arranged for coupling to the wheel hub, and a carrier portion for supporting the motor-vehicle wheel during a centering phase of the wheel on the hub. The tool has an inner tubular member and an outer tubular member rigidly connected to each other so as to be coaxial. At the coupling portion, the inner and outer tubular members are spaced apart so as to define a space arranged to receive an end portion of the wheel hub, in such a way that, in an operating condition, the end portion of the hub is interposed between the inner tubular member and the outer tubular member.

The wheel holding member for a vehicle has a rod-like shape, and includes: a thread portion, which is formed on an end portion on a proximal end side, and has a male thread threadedly engageable with a hub bolt hole formed in a wheel hub; a holding portion, which protrudes toward a distal end side with respect to the thread portion, and has no thread on an outer periphery thereof; and a tool insertion hole, which is exposed from an end surface on the proximal end side, and to which a tool for rotating the wheel holding member is insertable. A bottom surface of the tool insertion hole is located on the distal end side with respect to an end of the thread portion on the distal end side.

The present embodiments provide a mobile medical device with at least one motor-driven wheel. The mobile medical device is movable on the at least one wheel. The motor-driven wheel is arranged on a hub assigned to the motor-driven wheel. The motor-driven wheel is reversibly removable from the hub and is pluggable back onto the hub manually and without aids. The present embodiments provide that the motor-driven wheel may be removed rapidly manually and without additional aids.

A method of modifying a hub with a wheel adaptor. The wheel adaptor includes a cylindrical body, a first set of holes that includes six symmetrically spaced holes located at a first radial distance, a second set of holes that include three holes located at a second radial distance, and a third set of holes that include another three holes located at a third radial distance. The method includes coupling the wheel adaptor to the hub. The coupling includes passing six symmetrically spaced lugs of the hub through the wheel adaptor at the first set of holes and fastening using six hub lug nuts. The method further includes drilling six holes through the hub using the second set of holes and the third set of holes of the wheel adaptor as drilling guides.
