摘要： Disclosed are a folding wheel and a portable appliance. The folding wheel includes: a wheel body, wherein the wheel body include two wheel plates that can be spliced with each other, and a notched area is formed therebetween when the two wheel plates are spliced with each other; a first connecting element disposed in the notched area; a first slide rail mechanism, at least part of which is disposed on the first connecting element, and remaining parts of which are disposed on respective wheel plates, wherein the first slide rail mechanism includes a first rail groove and a first rotating shaft inserted into the first rail groove, such that the two wheel plates can be spliced with or separated from each other along the first rail groove via the first rotating shaft, and can be flipped relative to the first connecting element via the first rotating shaft; the folding wheel is foldable, wherein when the two wheel plates are pulled away from each other, the two wheel plates slide away from each other along the first rail groove. The two wheels may be flipped, wherein when the two wheel plates are folded towards each other, the portable appliance with reduced folded size facilitates the user to pack or carry.

摘要： Segmented wheels offer advantages in storage space of closely packed segments as compared to whole wheels. Individually damaged or worn segments may be replaced in the field with little or no need for jacks or cranes to support the rest of the vehicle, and entire wheels may be replaced or reconfigured from one tread type to another by swapping out segments not in contact with the ground and then driving the vehicle a distance which is a fraction of the circumference of its wheels to expose the remaining segments for retrofit. Segments may be freely supported by rigid or compliant spokes or may be bound together by straps or designed to interlock with adjacent segments. Embodiments of the invention may be made in any size range including applications for bicycles, agricultural machinery, cars, trucks and mining machinery and vehicles.

摘要： Embodiments of collapsible wheels and methods of making collapsible wheels are generally described herein. The collapsible wheels can each comprise a plurality of wheel sections, a plurality of rims, and spokes connecting the plurality of wheel sections to the plurality of rim portions. The plurality of rim portions are positioned along a perimeter of a circle that defines a central plane of the wheel. Each wheel section supports one or more spokes that connect to one or more of the rim portions. The wheel sections are rotatable relative to each other around an axis from a collapsed configuration to an expanded position. Other embodiments may be described and claimed.

摘要： A wheel assembly including a rigid wheel and a flexible tire. The rigid wheel includes a radially outer rim wall, a plurality of mounting elements, and a plurality of inflatable spacers between the mounting elements. The flexible tire may be mounted on the mounting elements of the rigid wheel such that portions of the flexible tire between the mounting elements are separated from the outer rim wall by spaces between the mounting elements and are configured to flex inwardly when subject to ground engaging pressure. The inflatable spacers limit the amount of inward flex of the inwardly flexible portions of the flexible tire.

摘要： A wheel assembly includes a collapsible wheel and an airless flexible tire mounted on the wheel. The wheel includes a central portion and a plurality of circumferentially spaced mounting elements attached to the central portion. Each of the mounting elements is movable between a retracted position and an extended position, and may be pivotally attached to the central portion of the wheel and configured to pivot between the retracted position and the extended position. The tire may be positioned on the wheel when one or more of the mounting elements is in the retracted position, and the one or more mounting elements are moved to the extended position wherein the mounting elements engage and support the tire.
