Abstract: A bi-axial ball tip for use with a mobility cane. The bi-axial ball tip includes an omni ball, at least two mirrored brackets, and a grip. The mirrored brackets form a chamber to accommodate part of the omni ball, allowing the omni ball to rotate around a horizontal axis inside the chamber. The rotation of the omni ball when the ball engages a ground surface and is provided to aid visually impaired people. The grip connects the mirrored brackets in a manner such that the mirrored brackets and the omni ball, together, rotate around a vertical axis which is orthogonal to the horizontal axis.
Abstract: An aircraft wheel assembly that includes first and second hub components having an axis and respective first and second sets of circumferentially spaced apart interface elements. The first and second hub components may be rotatable relative to one another about the axis between a first position and a second position. In the first position, the first set of interface elements is axially movable relative to the second set of interface elements. In the second position the first set of interface elements axially overlaps the second set of interface elements to prevent axial movement of the first hub component relative to the second hub component.
Abstract: The TTAssembly is a three tire and rim wheel assembly. The assembly consists of a large diameter center wheel with two identical smaller diameter wheels on the inboard and outboard sides respectively. The TTAssembly replaces the standard single rim single tire assemblies on a vehicle hub, maximizing gas mileage and the safety requirement of the vehicle. It also reduces maintenance costs and eliminates the need for a spare tire.
Abstract: A traveling toy wheel whose simple configuration allows multiple devices to be enjoyed and can further change fine offsets is provided. The traveling toy wheel includes a first rim member to which a tire is mounted and a second rim member which includes a fitting portion into which a wheel hub of a traveling toy is fitted. Fitting holes as fixing portions are provided in one of the first rim member or the second rim member and elastic convex pieces as fixed portions are provided in the other of the first and second rim members. When the elastic convex pieces are fitted in the fitting holes, the first rim member and the second rim member are jointed relatively unmovably. A plurality of fitting holes are arranged at different positions, so that it is possible to easily adjust an offset of the wheel.
Abstract: A split wheel assembly for reception of pneumatic tires is provided with a safety feature to ensure that the two halves of the wheel cannot be dismantled when the tire thereon is pressurized. The assembly flanges of the two wheel portions have series of assembling apertures which register in pairs. The aperture on one of the flanges is circumferentially extending, and has a narrow end and a broad end. The narrow end of the aperture extends to an axially extending depression on the surface presented towards the flange of the other rim section. A bolt passes through the apertures, for assembling purposes, the bolt having a washer which fits into the depression, and having a securing nut which is sized so as to pass through the broad end of the aperture but not through the narrow end.
