A non-pneumatic tire includes an inner ring, an outer ring, and a plurality of loops extending between the inner ring and the outer ring. The plurality of loops including at least a first loop and a second loop, wherein the first loop and the second loop are each in direct contact with both the inner ring and the outer ring. The first loop has a single reinforcement layer disposed therein, and includes a first extent that extends between the inner ring and the outer ring and a second extent that extends between the inner ring and the outer ring. The second loop has a single reinforcement layer disposed therein, and includes a third extent that extends between the inner ring and the outer ring and a fourth extent that extends between the inner ring and the outer ring. The second extent is in direct contact with the third extent.

A system cures and manufactures a partially-cured tire assembly. The system includes a plurality of elongate spacer members for maintaining corresponding a uniform cavity tension in the partially-cured tire assembly, each spacer member including a first longitudinal body member axially opposed to a second longitudinal body member, two cam bolts for adjusting a radial gap between the first longitudinal body member and the second longitudinal body member, and two springs each attached to the first body member and the second body member for maintaining a radial compressive force against the cam bolts; a first annular curing platen for securing spacer members relative to each other; and a second annular curing platen for securing spacer members relative to each other.

An improved wheel for a mobility apparatus designed is disclosed herein. The wheel conforms to obstacles in the ground, creating a smoother walking experience. The inner web of a tire of the wheel preferably consists of polygonal reliefs offset from each other over multiple layers in a radially symmetric pattern to create a web which naturally compresses to absorb shock from obstacles. The tire's inner core preferably consists of a hexagonal membrane that extends parallel to the axel of the tire and extends out of each side of the wheel such that it is visible.

A tyre comprising an adaptive tread, the adaptive tread comprising a plurality of surface sections, wherein each surface section can move without deformation relative to the other surface sections to form a tread pattern.

A non-pneumatic tire (101) having a hub (201) and a compliant outer band (109) connected by connecting members (129) that are intersected by an intermediate band (120) positioned between the hub (201) and compliant outer band (109) forming a plurality of connecting element segments (331,333), each segment having a predominant curvature extending in the same longitudinal direction said direction coinciding with the preferred direction of rotation of the tire (101).

A tire is configured to be received by a wheel having at least one angled surface. The tire includes a tread portion, a first sidewall, and a second sidewall. The first sidewall has a first outer surface, a first inner surface, and a first projection extending inwardly from the first inner surface. The first projection has a first angled surface configured to engage a first corresponding surface of a wheel. The second sidewall has a second outer surface, a second inner surface, and a second projection extending inwardly from the second inner surface. The second projection has a second angled surface configured to engage a second corresponding surface of the wheel.

A tire and wheel assembly includes a tire, a circular hub member for securing to a rotatable axle of a vehicle, the rim piece having a first annular ring flange for engaging the tire, a rim piece for engaging the hub member, a second annular ring flange for engaging the tire, and a plurality of cylindrical shafts for each axially engaging the first annular ring flange at one axial end of each of the shafts and the second annular ring flange at another opposite axial end of each of the shafts.

A shear band and a non-pneumatic tire is described which includes a ground contacting annular tread portion; a shear band, and a connecting web positioned between a hub and the shear band. The shear band is preferably comprised of a three-dimensional spacer fabric having a first and second layer connected by connecting members. The three-dimensional spacer fabric has a defined depth. The first and second layer of fabric of the three-dimensional spacer structure are reinforced with a respective first and second layer of non-crimped fabric, eliminating the need for a rubber shear layer and reinforcement layers commonly used for the shear band.

CONSTRUCTIVE ARRANGEMENT OF A FLEXIBLE WHEEL FOR WHEELBARROW OR MANUALLY TRACTIONED INDUSTRIAL CARTS is constituted by a single block that comprehends three parts: the outer ring(1), the center wall(2), and the inner ring(3); and the outer ring(1) has on its extremity a tread surface(15), and as tangents on each side it has side tread surfaces(12); and each side tread surface(12) has a plurality of radial cavities(11) spaced along the wheel; and the radial cavities(11) of a side tread surface(12) are not aligned in relation to the radial cavities(11a) of the opposite side tread surface(12a); and the center wall(2) is a flat, solid, ring-shaped wall contained in the central plane which contains the body of the wheel, and on each side of the flat wall there are a plurality of flexible structures(14) radially aligned to the radial cavities(11) contained in the outer ring(1); and the inner ring(3) is constituted of a circular wall(31), a reinforcement rim(32), and mass reducers(33); and the mass reducers(33) are recesses with radial walls.

A non-pneumatic tire with an annular body of resilient elastomeric material comprises circumferential web members supported by a plurality of circumferentially spaced crossed spoke pairs. The thickness and angle of the spokes in each crossed spoke pair varies.
