The present steerable wheel assembly incorporates a lean-to-steer mechanism into an inner race of a roller bearing, while a wheel is mounted to an outer race of the roller bearing. A shaft extending from the mechanism is attached to a body, and the mechanism acts to steer the outer race and the wheel about a vertical steering axis when the shaft is tilted about a horizontal axis. The mechanism can be a pivot joint, providing a linear steering response, or can be a lean-to-steer mechanism that provides a non-linear response where the steering action is not proportionally responsive to tilting over the expected range of tilting.

A Single-foot Skateboard. The Skateboard has interchangeable components in order to reduce spare part inventory. The footboard of the Skateboard is reversible.

A wide wheel inline roller skate has a boot, a chassis, and a plurality of wheels. The boot is removably attached atop the chassis, and the plurality of wheels is rotatably connected to the chassis opposite the boot. Each of the plurality of wheels is bi-directionally tapered from a medial diameter outward to a lateral diameter, wherein the medial diameter is larger than the lateral diameter. Thus, the wide wheel inline roller skate affords greatly increased surface area contact between a supporting ground surface and any given wheel, thereby increasing stability and safety, compared to conventional in-line roller skates, particularly while turning.

The mechanism can be a pivot joint, providing a linear steering response, or can be a lean-to-steer mechanism that provides a non-linear response where the steering action is not consistently responsive to tilting over the expected range of tilting. The present non-linear lean-to-steer mechanisms can also be incorporated into alternative lean-to-steer devices, and alternative mechanisms can employ tracking structures to coordinate tilting motion of a first moving element with steering motion of a second moving element to provide a non-linear lean-to-steer response.

There is provided a guard for an in-line roller skate, which includes an elongated member defining a wheel receiving channel. The channel has a bottom and a pair of opposed sidewalls, which extend upwardly from the bottom terminating in a remote edge. The remote edge of the sidewalls define a wheel insertion opening to receive wheels of an in-line roller skate. At least one transverse roller is positioned across the channel near the remote edge of the sidewalls.

A tracked skate runner provides a low-profile substitute for a wheel with exceptionally low rolling resistance on rough or soft terrain. The runner includes a skate frame and rollers that bear against an endless track of hinged links devoid of pinch points that can get jammed with ground debris. The skate frame provides a channel with sidewalls and a top dirt shield. The sidewalls fit closely with the links of the track to seal out dirt, and the top dirt shield protects the rollers from dirt that shakes off the top recirculating portion of the track.
