Rolling device comprising a housing (11) accommodating a rolling element and a control and communication module comprising a wireless receiver (30) connected to a control device (40) and position means (50) connected to the control device, wherein the rolling device further comprises driving means (60) connected to the control device and the rolling element for driving and controlling the movements of the rolling element according to a first position acquired by the position means and a received wireless signal comprising movement instructions and a second position, power supply means (70) for powering the control and communication module and the driving means, wherein the housing is arranged with an support assembly for bearing the rolling element which is configured for establishing a releasable connection with the housing, and an electrical interface adapted for establishing connection between the rolling element and the control and communication module and the power supply means.

A rolling device having a bearing housing accommodating a wheel axle, a drive motor with first and second motor parts for conduction of relative rotation between a wheel element and the wheel axle, end portions of the wheel axle being connected to axle support members in an eccentric position displaced from the center line of the axle support members, and locks operable between an unlocked position allowing rotation of the axle support members relative to the bearing housing, and a locking position preventing the rotation of the axle support members, wherein in the unlocked position, the motor conducts rotation of the axle support members and wheel axis for displacement of the wheel element by an eccentric movement between an extended position where at least a portion of the wheel element projects outside the bearing housing and a retracted position where the wheel element is located inside the bearing housing.

A roller assembly comprises a housing having an outer surface attached thereto, and a braking arrangement positioned at least partially within the housing. The braking arrangement is configured to increase resistance to rotation of the housing proportionally to a load applied against the outer surface.

A brake mechanism for a brake caster is disclosed. In various embodiments, the brake mechanism includes a shaft; a guide plate having a roller; and a slider plate having a first axial facing surface with a slider plate trough and a slider plate peak, the slider plate configured to slide on the shaft in response to the roller interacting with the slider plate trough and the slider plate peak.

A new and improved anatomical imaging system which includes a new and improved movement system, wherein the movement system comprises an omnidirectional powered drive unit and wherein the movement system can substantially eliminate lateral walk (or drift) over the complete stroke of a scan, even when the floor includes substantial irregularities, whereby to improve the accuracy of the scan results and avoid unintentional engagement of the anatomical imaging system with the bed or gurney which is supporting the patient. The present invention also comprises the provision and use of Liddiard wheels.

A base module is for a mobile medical system, designed to cover distances autonomously or semi-autonomously. The base module includes a chassis having a plurality of rolling bodies. The rolling bodies are mounted to rotate about axes of rotation and, via adjusting devices, are adjustable in the vertical direction such that each respective rolling body is movable between a first position, in which the respective rolling body is in contact with a floor area, and a second position, in which the respective rolling body is spaced apart from the floor area. A medical system includes a base module of an embodiment. A method for operation of the medical system is also disclosed.

An example article of furniture includes a number of furniture legs having mechanically coupled thereto a respective furniture caster having a rolling component. The furniture casters are movable between (i) an extended position in which their rolling components at least partially extend below bottom surfaces of the furniture legs and (ii) a retracted position in which their rolling components are positioned entirely above the bottom surfaces of the furniture legs. Push-pull cables are mechanically coupled to the furniture casters, and at least one actuator is mechanically coupled to the push-pull cables. When actuated, the actuator applies a pushing force to the push-pull cables, thereby causing the furniture casters to transition from the retracted position to the extended position. When the actuator is not actuated, the pushing force is removed from the push-pull cables, thereby causing the furniture casters to transition from the extended position to the retracted position.

The present disclosure relates to the technical field of rollers, and provides a roller assembly, including: a fixing cover, a roller, a round magnet and a rotating shaft. The roller assembly further includes a bearing. The bearing is coaxially connected to an end of the rotating shaft; the roller is coaxially sleeved on an outer surface of the bearing; and the round magnet is coaxially connected to another end of the rotating shaft. By this way, the bearing structure is more precise, thereby enabling a better customer experience, a longer product life, and a simple structure for easy installation.

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.
