A mechanism for deploying and retracting an adjustable handling wheel from under different types of equipment supported on the floor, or different types of furniture, such as chairs, medical chairs, nursery chairs, examination chairs, bedside tables, beds without chassis, cabinets and others. The mechanism enables very easy handling and movement of the equipment or furniture from one place to another place.

Particular embodiments disclosed herein provide a retractable guard assembly coupled to a caster of a mobile equipment, comprising a housing and one or more guards at least partially disposed in the housing. The one or more guards are independently movably coupled to the housing. The retractable guard assembly further comprises corresponding one or more biasing elements coupled to the one or more guards and to the housing for biasing the one or more guards towards a fully deployed state. When the one or more guards are in the fully deployed state, contact between a fixed object and a portion of the one or more guards disposed outside the housing causes the one or more guards to transition into a retracted state, and when the contact is removed, the corresponding one or more biasing elements cause the one or more guards to transition into the fully deployed state.

A removable transport caster assembly secured to side to side beams or front to back beams in a data center cabinet in a data center. The removable transport caster assembly is temporarily installed on the cabinet to enable the cabinet to be relocated to another location in the data center. The removable transport caster assembly includes a transport caster and a transport caster bracket secured to the transport caster. The transport caster has a mounting plate, a mounting bracket extending from the mounting plate, a lifting plate pivotally connected to the mounting plate, a lifting lever pivotally connected to the mounting bracket and a wheel assembly. The transport caster bracket secures the transport caster to the cabinet when relocation of the cabinet is desired.

A system for sensing the angular position of a caster wheel includes a sensor mounted on a bearing which supports a shaft aligned with the rotational axis of the caster. A target on the shaft is detected by the sensor which generates signals indicative of the presence or absence of the target. The position of the target is coordinated with the position of the caster wheel such that the signals are indicative of the angular position of the caster wheel. The target may be a groove extending partially around the shaft and a remaining ungrooved portion of the shaft.

A patient transport apparatus transports a patient over a floor surface. The patient transport apparatus comprises a support structure and support wheels coupled to the support structure. An auxiliary wheel is coupled to the support frame to influence motion of the patient transport apparatus over a floor surface. The auxiliary wheel is movable to a deployed position with the auxiliary wheel engaging the floor surface and a stowed position with the auxiliary wheel spaced a distance from the floor surface. An actuator assembly including a lift actuator a biasing device, and a biasing load adjustment assembly. The lift actuator is operable to move the auxiliary wheel to the deployed position and to the stowed position. The biasing device configured to bias the auxiliary wheel towards the deployed position. The biasing load adjustment assembly configured to adjust a biasing force being applied by the biasing device to the auxiliary wheel.

Medical device capable of properly measuring a center of gravity and capable of preventing overturning of a surgical operation table is provided without performing a significant design change. Medical device S, which includes a plurality of leg portions 20 that lift up a main body 2 from a floor surface and support the main body 2, includes load detection devices 55 that are provided between the main body 2 and the respective leg portions 20, and detect loads in a vertical direction received by the leg portions 20 from the floor surface.
