Wearable device

摘要

A wearable device configured to selectively provide roller transportation includes a shoe configured to at least partially accept a foot of a user of the wearable device, the shoe comprising a foot interface surface configured for selective contact with a bottom of the foot, a wheel assembly configured to selectively roll relative to a ground surface in response to rotation of at least a portion of the wheel assembly about an axle that is substantially coincident with an axis of rotation, and a frame connected between the shoe and the wheel assembly, the frame being configured to selectively transfer forces between the shoe and the wheel assembly and the frame comprising a clearance plane vertically offset from the ground surface.

主权项

1. A device, comprising:
a frame comprising (1) a clearance plane vertically offset from a ground surface and (2) an upper interface surface located vertically higher relative to the clearance plane; two front wheel assemblies connected to the frame, the two front wheel assemblies comprising an inner front wheel assembly and an outer front wheel assembly, wherein each front wheel assembly comprises an axle having an axis of rotation and a center of rotation that is coincident with the axis of rotation, and wherein each front wheel assembly is configured to selectively roll relative to the ground surface in response to rotation of at least a portion of the front wheel assembly about the axle and its respective axis of rotation; and two rear wheel assemblies connected to the frame, the two rear wheel assemblies comprising an inner rear wheel assembly and an outer rear wheel assembly, wherein each rear wheel assembly comprises an axle having an axis of rotation and a center of rotation that is coincident with the axis of rotation, and wherein each rear wheel assembly is configured to selectively roll relative to the ground surface in response to rotation of at least a portion of the rear wheel assembly about the axle and its respective axis of rotation; wherein the center of rotation of each axle of the two front wheel assemblies and the two rear wheel assemblies is located vertically higher than the upper interface surface; wherein each wheel assembly is movable in a forward-rearward direction relative to the frame, and wherein each wheel assembly is movable in an upward-downward direction relative to the frame; wherein the distance between the two rear wheel assemblies is less than the distance between the two front wheel assemblies; and wherein the distance between the outer front wheel assembly and the outer rear wheel assembly is less than the distance between the inner front wheel assembly and the inner rear wheel assembly.
