A transport cart (3) and a transmission device thereof (32). The transmission device comprises: a crawling assembly (320), a rotary drive assembly and a crawling drive assembly. The crawling assembly comprises: a wheel frame (321), comprising a first end and a second end opposite to the first end, the wheel frame extending from the first end to the second end; a driving wheel (322), mounted at the second end and having an axis perpendicular to the extending direction of the wheel frame; and a guide wheel (323), mounted at the second end and having an axis parallel to the extending direction of the wheel frame. The present transport cart provided with the described transmission device may move along both a horizontal rail and a vertical rail and may quickly switch between the horizontal rail and the vertical rail, thus improving the moving efficiency.

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 object to provide a brake device for a caster that has a simple structure, provides reliable braking, has no risk of damaging the circumferential surface of a roller, and has high durability. The brake device for a caster includes: a plurality of projecting parts formed concentrically at regular intervals on opposite side-surfaces of a roller in a direction in parallel with the axis, and levers set across the roller at both side-panels of a fork so as to be opposed to the projecting parts, and a claw formed at a tip of each of the levers so as to be opposed to the projecting parts, wherein the levers are operated so that the claw is engaged with a concave part formed between the projecting parts, thereby locking rotation of the roller.

A wheel includes a wheel rim, a hub defining a hollow housing for a wheel mount, and three or more resilient and equidistantly spaced spokes extending between an outer circumferential surface of the hub and an inner circumferential surface of the wheel rim. Each spoke is defined by a flexed, elongate spring element having a length that is greater than the radial distance between the outer circumferential surface of the hub and the inner circumferential surface of the wheel rim. The spring element is tangentially fixed at or towards one end to the outer circumferential surface of the hub and tangentially coupled at or towards its other end to the inner circumferential surface of the wheel rim via a hinged connection. The tangential coupling at the wheel rim is spaced circumferentially from the tangential fixing at the hub in a predetermined direction by a predetermined angle.

A caster wheel brake and anti-swivel system for carts and other wheeled articles is operable to secure free-castering wheels against swiveling rotation about their swivel axes, and against rolling rotation along their horizontal rotation axes. The system includes a swiveling caster wheel assembly and an actuation link, with an anti-swivel actuator and a brake actuator coupled thereto. Linear movement of the actuation link causes the anti-swivel actuator to engage the anti-swivel member that rotates with the caster wheel about the swivel axis, to selectively prevent the anti-swivel member and wheel from swiveling. The actuation link's movement also urges a brake actuator to move a wheel brake and drives a braking surface into engagement with the wheel, thereby preventing the wheel from rolling at the same time it is prevented from swiveling by the pawl. Optionally, a foot-operated torque shaft and a rack-and-pinion arrangement are used to operate the actuation link.

A caster wheel brake system for carts and other wheeled articles is operable to secure caster wheels against rolling rotation along their horizontal rotation axes. The system includes a pivotable parking brake lever, an actuator arm, and a torque shaft extending between the brake lever and actuator arm. The brake lever includes a distal end portion for selectively engaging a caster wheel, a proximal end portion opposite the distal end portion, and a pivot coupling, the latter being pivotably secured to the cart or wheeled article. An actuator arm extends outwardly from a distal end portion of the torque shaft, with the actuator arm slidably engaging the proximal end portion of the brake lever. The torque shaft and the actuator arm are rotatable together to urge the brake lever toward the braking or non-braking position

An aircraft galley cart is disclosed. In embodiments, the galley cart includes two adjacent portions (e.g., left and right side) hingedly or slidably connected. The galley cart has a default configuration compatible with galley cart bays of galley structures. The galley cart may be transitioned into a narrow configuration by articulating the left-side portion relative to the right-side portion (e.g., by pivoting or rotating the left-side portion). When in the narrow configuration, the galley cart may be twice as long but half as wide, allowing passenger access through an aisle without removing the galley cart back out of the aisle and disrupting in-seat food and beverage services. The galley cart includes auxiliary casters that deploy during transition to support the main casters in keeping the galley cart balanced and mobile in the narrow configuration.

A caster wheel brake and anti-swivel system for carts and other wheeled articles is operable to secure free-castering wheels against swiveling rotation about their swivel axes, and against rolling rotation along their horizontal rotation axes. The system includes a swiveling caster wheel assembly and an actuation link, with an anti-swivel actuator and a brake actuator coupled thereto. Linear movement of the actuation link causes the anti-swivel actuator to engage the anti-swivel member that rotates with the caster wheel about the swivel axis, to selectively prevent the anti-swivel member and wheel from swiveling. The actuation link's movement also urges a brake actuator to move a wheel brake and drives a braking surface into engagement with the wheel, thereby preventing the wheel from rolling at the same time it is prevented from swiveling by the pawl. Optionally, a foot-operated torque shaft and a rack-and-pinion arrangement are used to operate the actuation link.

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 transport vehicle includes: a vehicle body (31) and a first traveling mechanism (32) mounted on the vehicle body (31). The first traveling mechanism (32) includes a plurality of crawling assemblies (320) respectively provided on two opposite sides of the vehicle body (31). Each crawling assembly (320) includes: a wheel carrier (321) extending outwardly from a lateral side of the vehicle body (31); and a driving wheel (322) mounted on the wheel carrier (321), the driving wheel has an axis perpendicular to an extending direction of the wheel carrier (321). The wheel carrier (321) is rotatable about the central axis of the wheel carrier (321) in the extension direction.
