A suspension system for a vehicle includes a wheel carriage assembly, a gear box, and steering and caster subsystems. The wheel carriage assembly and the steering and caster subsystems are pivotable with respect to one another via the gear box. The gear box pivotably couples the steering and caster subsystems to the wheel carriage assembly by rotatable arms such that translational motion applied by actuators and/or motors is transferred between the steering and caster subsystems and the wheel carriage assembly via the gear box. In addition, the wheel carriage assembly and the gear box are pivotable with respect to a chassis of the vehicle via the steering and caster subsystems via actuators and motors. Sensors are provided throughout the suspension system to provide input to a controller that outputs instructions to the actuators and/or motors, allowing the suspension system to actively adjust the pitch and roll of the vehicle.

A spring-force adjustable, height-adjustable industrial caster assembly including a mounting plate, a swivel housing that swivels relative to the mounting plate, and a spring assembly having components that are moveable relative to the swivel housing to controllably alter spring deflection and/or caster wheel height, which components can be adjusted by accessing the height-adjustable industrial caster assembly from above, eliminating the need to raise a pallet truck or other moveable assembly to which the caster assembly is coupled, away from the floor to be able to access and adjust the industrial caster assembly.

A laundry treatment apparatus including a plurality of swivel casters. Two of the swivel casters are braked swivel casters. One of the swivel casters other than the braked swivel casters is a vertically adjustable swivel caster. The braked swivel casters restrain translational movement of the laundry treatment apparatus across a floor. The vertically adjustable swivel caster can help fix the position of the laundry treatment apparatus so as to restrain rocking and twisting of the laundry treatment apparatus.

A support device includes a base member, a caster assembly coupled to the base member including a caster pivotally coupled to the base member, at least two planar members positioned above the caster and pivotally coupled to one another by at least two opposing hinges, and a shaft positioned between the at least two opposing hinges and extending through the at least two planar members.

A weed trimmer trolley assembly includes a clamp which has a first portion that is closable with a second portion for securing around a pole of a weed trimmer. A swivel is rotatably disposed on the clamp and the swivel is positionable at a variety of angles with respect to the weed trimmer. A pair of legs is each coupled to and extends downwardly from the swivel. Each of the legs comprises a first half that threadably engages a second half such that each of the legs has an adjustable length. A pair of arms is provided and each of the arms is coupled to a respective one of the legs. A pair of rollers is each rotatably coupled to a respective one of the arms to support the weed trimmer and thereby assist a physically limited user with employing the weed trimmer.

The present disclosure relates in general to a ball wheel, assembly and method of use for providing omni-directional rolling support to an article of manufacture such as, e.g., mechanics creepers, crates, carts, dollies, stretchers, gurneys, litters, beds, prams, transports, and luggage. One aspect of the present disclosure includes a ball wheel for a ball wheel assembly. The ball wheel comprises a roughly spherical shaped body having a plurality of features on an exterior surface of the body configured to assist the ball wheel in overcoming obstacles/debris in the surrounding environment and being used on uneven surfaces. Another aspect of the present disclosure includes a ball wheel assembly comprising the ball wheel. The ball wheel assembly may include a housing with an interior socket and shock absorber that allows the ball wheel to rotate therein while providing a cushioning effect. A still further aspect of the present disclosure includes a plurality of ball wheel assemblies mounted on an article of manufacture. Yet another aspect of the present disclosure is a method of using the ball wheel assembly on an article of manufacture. An intended purpose of the present disclosure is to provide a ball wheel and assembly for an article of manufacture that is designed to overcome obstacles/debris in the surrounding environment and being used on uneven surfaces via the combination of the cushioning effect of the shock absorber and the plurality of features of the ball wheel.

An anti-shimmy device (200A,200B,200C,200D,200E,200F,200G,200H) is adapted for a wheel (102A,102B,102C,102D,102E,102F,102G,102H) of a child carrier (100A,100B,100C,100D,100E,100F,100G,100H). The anti-shimmy device (200A,200B,200C,200D,200E,200F,200G,200H) includes a connecting base (210A,210B,210C,210D,210E,210F,210G,210H), a wheel base (220A,220B,220C,220D,220E,220F,220G,220H), a spindle component (230A,230B,230C,230D,230E,230F,230G,230H) and a restraining mechanism (240A,240B,240C,240D,240E,240F,240G,240H). The connecting base (210A,210B,210C,210D,210E,210F,210G,240H) is connected to a frame (101A,101B,101C,101D,101E,101G,101H) of the child carrier (100A,100B,100C,100D,100E,100F,100G,100H).
