The mount includes a base formed of a substantially planar side wall and a substantially planar bottom wall. The interior surfaces of the walls intersect at a right angle. Each of the walls has an opening. The wall openings together form a recess adapted to receive the wheel. A first notched protrusion extends from the side wall interior surface and is intended to be received in a slot adjacent a cut-out on the side wall of a container on which the mount is installed. A second protrusion, having two portions situated as an angle extends from the bottom wall interior surface of the mount and is intended to be received in a slot adjacent a cut-out on the bottom of the container.

A method for manufacturing a wheel hub (300) for a non-pneumatic wheel (100). A sheet (332) of material may be folded, cut, bent, and otherwise processed to form portions of the desired wheel hub(300). The wheel hub (300) may be connected with an annular band (108) through load supporting members (106) that can be selectively connected and disconnected from the hub (300).

A caster device includes a support unit, two caster wheels, a resilient member, two friction wheels, and two protruding teeth units. Each of the caster wheels has an inner wheel surface and a plurality of meshing teeth that are angularly arranged and that are formed on the inner wheel surface. Each of the protruding teeth units includes a plurality of protruding teeth. The support unit is downwardly movable against a resilient force of the resilient member to a stop position, where each of the friction wheels is in frictional contact with the meshing teeth of a respective one of the caster wheels, and where the protruding teeth of each of the protruding teeth units are meshed with the meshing teeth of the respective one of the caster wheels.

A method and apparatus for levelling a transport carrier having eccentrically and centrically mounted wheels on a housing. The wheel/housing apparatus is adapted to reach mechanical equilibrium with rotation on a surface.

Work aid for a hairdresser, comprising a mobile frame on which frame a seat surface or at least one storage surface is arranged, wherein the frame comprises at least one castor being arranged rotatably in a fork head, and the castor being arranged on an axle, which axle is arranged insertably in each case with a first end portion on a first fork-shaped receptacle on the fork head and with a second end portion on a second fork-shaped receptacle on the fork head.

A driven caster wheel assembly may include a wheel, an axle, a drive assembly, a drive shaft, and a bevel gear. The wheel may be mounted to the axle for rotation about a drive axis and steering about a substantially vertical steering axis. The drive shaft may extend along the steering axis from a first end to a second end, with the first end being connected to the axle and the second end being connected to the drive assembly such that the drive assembly controls rotation of the drive shaft about the steering axis. The bevel gear may connect the first end to the axle such that rotation of the drive shaft about the steering axis controls rotation of the wheel about the drive axis to drive the driven caster wheel assembly in a substantially horizontal direction. Various other assemblies and methods are also disclosed.

Embodiments of the present disclosure generally relate to double-sided wheel assemblies and methods thereof. In one embodiment, double-sided wheel assembly is provided that may comprise a wheel member comprising a first wheel; a second wheel; and a center member disposed between the first wheel and the second wheel, the first wheel and second wheel adapted to distribute the load of the luggage; a wheel carriage for supporting the wheel member; and a wheel support base adapted to couple with the wheel carriage.

A bearing pusher assembly for moving product in a channel of a product display apparatus. The product display apparatus can have a tray component and a spring, the bearing pusher assembly to be coupled with the spring and moveable with respect to the tray component. The spring provides a resilience force to the tray component and the bearing pusher assembly upon deformation. The bearing pusher assembly includes a pusher body, an axle coupled to the pusher body, and a ball bearing coupled to the axle and rotatably moveable with respect to the tray component. Also disclosed is a product display apparatus including the bearing pusher assembly.

An electric vehicle has a structure mounted on balls which are arranged for rolling on the ground, wherein an actuating roller is associated with each ball. The roller-supporting structure is rotatably mounted about a substantially vertical axis within a main supporting structure which is rigidly connected to the ball-supporting member. The main support structure carries a first electric motor for controlling the rotation of the roller-supporting structure about the substantially vertical axis, while the roller-supporting structure carries a second electric motor for controlling the rotation of the roller about its axis.

A transportable carton assembly is disclosed that includes a carton defining a bottom rear corner edge portion having a pair of longitudinally spaced apart apertures formed therein, and an elongated shield retained within the bottom rear corner edge portion of the carton and including a pair of longitudinally spaced apart wheels positioned to extend through the longitudinally spaced apart apertures formed in the bottom rear corner edge portion of the carton for transporting the carton over a surface.
