A wheel for a non-motorized vehicle (e.g., a shopping cart) can include a housing assembly and a tread assembly. The housing assembly can be configured to sealingly house electronics or other components. The tread assembly can removably mate with the housing assembly such that the electronics or other components remain closed and/or sealed within the housing assembly when the tread assembly is mated or unmated with the housing assembly.

A front suspension wheel for mobile robotic devices that can be compressed into or decompressed out of a main body of a mobile robotic device to facilitate driving the mobile robotic device over obstacles, thresholds and the like. The wheel will provide the mobile robotic device with information such as how fast the wheel is traveling. The wheel is easily removable by hand by the user.

A robot cleaner includes: a body having a suction port; a plurality of wheels for movement of the body; and a plurality of driving devices configured to drive the plurality of wheels, respectively, wherein each of the plurality of wheels includes an inner wheel and an outer wheel having a thickness that is larger than a thickness of the inner wheel, and each of the inner wheel and the outer wheel includes a plurality of slits.

An all-terrain load transport system including a cylindrical first base member and at least three pairs of arms is provided. A handle is removably attached to an attachment member disposed on the cylindrical first base member. The cylindrical first base member defines a space for receiving at least one piece of accessory equipment. Each pair of the three pairs of arms defines a wheel support assembly at an end of each pair distal from an outer periphery of the cylindrical first base member. The three pairs of arms are detachably attached to the outer periphery of the cylindrical first base member. The wheel support assembly includes a cylindrical second base member defining a space for receiving a spherical wheel. The spherical wheel moves omnidirectionally within the defined space. Roller bearings positioned along an inner periphery of the cylindrical second base member facilitate the omnidirectional movement of the spherical wheel.

An apparatus includes first and second side portions, and a horizontal portion disposed between the first and second side portions. Each side portion includes an inner wall joined to the horizontal surface, an exterior wall, and a top portion connected that define a volume within the side portion. Each side portion also includes first and second wheels within the volume, the first and second wheels having a raised wheel position and a lowered wheel position. Each side portion also has an arm coupled to the outer wall of the side portion, the arm having a first arm position and a second arm position. Movement of the arm from the first arm position to the second arm position causes the wheels to move from the raised wheel position to the lowered wheel position.

The present invention discloses an obstacle-adaptive mechanism of a moving device, which uses a driving wheel, a driving gear, a passive wheel, a passive gear and an intermediate gear as a transmission mechanism, wherein the driving gear is connected to one side of the driving wheel, the passive gear is connected to one side of the passive wheel, the intermediate gear is disposed between the driving gear and the passive gear to keep the driving wheel and the passive wheel rotating in the same direction to help crossing an obstacle, thereby preventing the obstacle-adaptive mechanism from being stuck by the obstacle and allowing the obstacle-adaptive mechanism to successfully crossing the obstacle. Therefore, the obstacle-adaptive mechanism of the moving device can provide the ability for crossing obstacles.

A support foot where the support foot main body is composed of a ground face, support slot and long groove. The support slot is situated on the opposite side of the grounded face and the mouth is upward-opening, and a support arm is situated above the support slot. The long groove is cut through the support arm and runs parallel to the axis of the support slot, and a rivet inserted through the long groove is used to attach the support foot to the rack. This invention consists of a support foot designed as a single unit. It is attached by a single rivet and can be folded either inward for storage or outward to form a support structure by means of the connection at the support slots.

Embodiments of the present application disclose a universal wheel assembly and a smart cleaning device having the same. The universal wheel assembly includes a rotating shaft support and a universal wheel support. The rotating shaft support is configured to be fixed to a predetermined mounting position. The universal wheel support is connected to the rotating shaft support and is rotatable relative to the rotating shaft support. The universal wheel support is provided with a through hole, and the through hole is used for a mounting tool to pass through to fix the rotating shaft support to the predetermined mounting position.

A roller kit for a power washer surface cleaner attachment. A roller mount includes a bracket mounting a roller for rotation with respect to the roller mount and a clip for securing the roller kit to the surface cleaner attachment such that the roller is operatively aligned with the surface cleaner attachment for rolling over a surface to guide movement of the surface cleaner attachment along said surface. The clip includes a base portion supporting the bracket and an arm portion opposing the base portion. The clip is configured to bend resiliently in an opening direction to define an opening between the arm portion and the base portion for receiving a side wall of the shroud and to rebound in a gripping direction to grip the side wall between the arm portion and the base portion and thereby secure the roller kit to the surface cleaner attachment.

An apparatus includes first and second side portions, and a horizontal portion disposed between the first and second side portions. Each side portion includes an inner wall joined to the horizontal surface, an exterior wall, and a top portion connected that define a volume within the side portion. Each side portion also includes first and second wheels within the volume, the first and second wheels having a raised wheel position and a lowered wheel position. Each side portion also has an arm coupled to the outer wall of the side portion, the arm having a first arm position and a second arm position. Movement of the arm from the first arm position to the second arm position causes the wheels to move from the raised wheel position to the lowered wheel position.
