A low profile wheel assembly suitable for use in dollies, decks or any other platform designed for moving freight or other heavy items. It includes a wheel, a carriage on which the wheel bracket is mounted for rotation about a first axis. The wheel carriage unit fits inside an outer housing unit of this wheel assembly and by means of low friction between the wheel carriage unit and the outer housing unit enabling the wheels carriage unit to rotate concentrically while inside the outer housing unit at a different axis than the first. In this manner and at the same time that the wheel is rolling on a surface, it can change directions of where it is rolling to.

A wheel that deforms to absorb force is provided. The wheel includes one or more deformable spokes that extend from a central portion of the wheel to an outer portion of the wheel. The spokes are configured to interface against neighboring spokes after a spoke is sufficiently deformed. The neighboring spoke provides some support to the deformed spoke, thereby requiring an increased marginal force to further deform the first spoke. In one embodiment the wheel includes a plurality of pairs of spokes that are configured to interface against each other.

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 braking caster is provided that includes casters, a frame, braking plates, and springs. One end of a spring is hung on to the spring hook of the brake plate, and the other end is hung on to the frame. As the unstable status is caused by the spring swinging with the brake plate to the position of the rivet, the manually driven brake handle bypasses the unstable status, and can achieve stable braking and released statuses.

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.

Bicycle transport containers include a typically parallelepiped-shaped outer container. Retaining and/or receiving elements are provided inside the outer container for receiving bicycle elements such as bicycle frames, wheels and the like. In order to facilitate the transport of a bicycle transport container, the invention provides rolling elements on a bottom element of the outer container.

A multi-terrain cart, comprising a cart body, two front and two rear non-pivoting wheels, a swivel wheel positioned forwardly or rearwardly to the front and rear non-pivoting wheels, respectively, an actuator for applying a downward force to the swivel wheel which causes the swivel wheel to be set at an operative position and two of the non-pivoting wheels to be raised relative to an underlying ground surface, and means for setting an angle of the swivel wheel relative to a lengthwise extending centerline of the cart body to cause the cart to rotate about a center of rotation that is determined by the set angle of the swivel wheel.

A cart suspension device or system, or a castor equipped cart or platform having such a cart suspension system or device which reduces noise and vibrations when in use. The cart suspension device or system, or castor equipped cart or platform having such a cart suspension system or device utilizes a swing arm or a one-piece spring bracket and a shock pneumatic rubber damper to greatly reduce the noise and vibration inherent in carts rolling over uneven surfaces.

According to an example aspect of the present disclosure, there is provided a novel caster assembly for a roll container (1000). The caster assembly has a caster (410) with a fork (411) as well as a pin (414). The pin (414) may be repeatedly attached to and removed from the fork (411) so as to attach the chassis (100) of the roll container (1000) to the fork (411). The pin (414) also acts as the hinge pin of a pivotable side wall (200) of said roll container (1000).

A brake device for a swivel caster has high durability with a simple power transmission structure, wherein a brake shoe is disposed so as to face a peripheral surface of a wheel of the swivel caster, a cable connected to an operation lever is inserted into a pivot shaft of the caster to be connected to the brake shoe, and a ball chain is interposed at least in a part of the cable inserted into the pivot shaft.
