Abstract
A wheel having rim support structure that affords access to a load connection structure within the wheel. The load connection structure may be configured for movement in response of a force. A rotatable mount bracket is provided on the rim support structure and guides movement of the load connection structure. Various embodiments are disclosed including internal drive and non-internal drive, roller and gear based driving, access on one or both sides of the wheel device, and other features and embodiments.
Claims21
A wheel device, comprising:
- a rim having an axis of rotation;
- a rim support structure coupled to the rim and defining a first access opening;
- a load connect structure that is accessible through the first access opening and configured to move up and down;
- and
- a movable mount bracket coupled to the load connect structure in a manner that guides the up and down movement of the load connect structure;
- wherein the mount bracket is configured for rotatable movement.

A wheel device, comprising:
- a rim having an axis of rotation;
- a rim support structure coupled to the rim and defining a first access opening;
- a rotatable mount bracket coupled to the rim support structure adjacent the first access opening and configured for rotational movement relative to the rim support structure;
- and
- a load connect structure that is accessible through the first access opening and configured to move up and down;
- wherein rotatable mount bracket and the load connect structure are pivotally coupled to one another at a first pivot axis;
- and
- wherein the rotatable mount bracket rotates coaxially with the axis of rotation of the rim.
5 more elements
An internal drive wheel device, comprising:
- a rim having an axis of rotation;
- a rim support structure coupled to the rim and defining a first access opening;
- a rotatable mount bracket coupled to the rim support structure adjacent the first access opening and configured for rotational movement relative to the rim support structure;
- and
- a load connect structure that is accessible through the first access opening and configured to move up and down in response to a shock force;
- a shock absorber that receives a compressive force from the load connect structure and returns the load connect structure to an at-rest position in the absence of that compressive force;
- a drive mechanism coupled to the rim;
- and
- a drive motor that drives the drive mechanism to in turn drive the rim;
- wherein, in the presence of a compressive force, the load connect structure moves down relative to the rim, the shock absorber compresses and the mount bracket rotates, the load connect structure and the shock absorber move with the mount bracket.
