An apparatus for assembling a non-pneumatic tire that includes a base and a plurality of elements that move relative to the base. The plurality of elements have a central axis, and the elements are disposed in a circumferential direction around the central axis and move in a radial direction towards and away from the central axis. A radial movement member, hub, and a plurality of spokes are also present. Each one of the spokes is disposed between adjacent ones of the elements. The elements and the spokes are moved inwards in the radial direction by the radial movement member towards the central axis so that the spokes are moved in the radial direction towards the hub. Adhesive engages the spokes and the hub at an attachment location of the spokes and the hub.

An apparatus to scoop debris from a surface is described. The apparatus comprises a trolley frame, a first and second wheels coupled to a first and second gear assemblies and designed to rotate in a first direction of rotation. The first and second gear assemblies are coupled to a opposite sides of the trolley frame. The apparatus further comprises an axle coupled to the trolley frame, using the first gear assembly and the second gear assembly, wherein the axle is configured to rotate in a second direction opposite to the first direction of rotation of the first wheel and the second wheel. A plurality of parallel spokes is attached to the axle that rotate with the axle, wherein each of the plurality of spokes are bent at an angle at their respective ends. A detachable debris collection net is coupled to the trolley frame.

A tire/wheel assembly of the present disclosure includes a tire with a tread portion and a wheel with a rim. The tire is mounted on the rim, and the tire/wheel assembly includes a power reception coil. In the contact patch when the tire/wheel assembly is filled to a prescribed internal pressure and subjected to the maximum load, the rectangle ratio of the ground contact length at a position, in the tire width direction, located 10% of the ground contact width inward in the tread width direction from an edge in the tire width direction to the ground contact length at the center of the contact patch in the tire width direction is 50% or more.

Described herein are various improvements to mobility devices. These improvements include, for example, adjustable lateral body supports, multi axial supports for accommodating movement of the pelvis during walking, frame folding assemblies for accommodating storage and transportation, detachable support couplings for supportive accessories, foldaway footplate assemblies for allowing users to rest, wheel brake systems, caster wheel systems, suspension support systems, control button assemblies, and center of gravity adjustment assemblies. One or more these improvements can be combined into various mobility devices as will be described in more detail hereinafter.

A rim for a bicycle wheel includes a radially inner portion disposed along an inner circumference of the rim, a first sidewall, and a second sidewall spaced apart form the first sidewall. The first sidewall and the second sidewall extend radially outward from the radially inner portion. The radially inner portion includes a stack of strips of material. The stack of strips includes a plurality of strips and a hole through the plurality of strips. The plurality of strips are nonparallel to each other. The plurality of strips are positioned about the hole through the plurality of strips.

A rim for a bicycle wheel includes a radially inner portion disposed along an inner circumference of the rim. The rim also includes a first sidewall, a second sidewall spaced apart from the first sidewall, and a radially outer tire engaging portion disposed along an outer circumference of the rim. The first sidewall, the second sidewall, the radially outer tire engaging portion, the radially inner portion, or any combination thereof includes a composite laminate. The composite laminate includes a layer of a composite material. The composite material includes a matrix of a polymer-based material and natural fibers of a reinforcing material. A volume of a respective one of the natural fibers of the layer of the composite material is greater before lamination of the composite laminate compared to the volume of the respective one natural fiber after the lamination of the composite laminate.

Wheel comprising a rim and a wheel center wherein the wheel center comprises several spokes extending in a longitudinal direction from a wheel hub to the rim. At least one spoke comprises an outer wall surrounding a cavity extending in the longitudinal direction of the at least one spoke. The cavity is delimited from the outer wall by an inner surface. The at least one spoke further comprises a reinforcing member extending along the inner surface.
