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 transportation assembly for transportation of an object on a surface comprises at least four rolling devices, a transportation body and at least one interface element for each rolling device. The interface element is adapted for connecting the rolling device to the transportation body. The interface element for mounting or integration of a rolling device to/into an object comprises an upper part and a lower part, where the upper part and the lower part comprise complimentary shaped guiding means.

A revolving shelf system including first and second side plates configured to be mounted on opposite side walls of a cabinet, a drive track configured to extend from an inner front face to an outer back face of each of the first and second side plates, at least one shelf member having first and second ends connected to the drive track, and a drive mechanism located on the outer back face of at least one of the first and second side plates, the drive mechanism configured to move with a rotation motion the at least one shelf member about the drive track.

The present disclosure generally relates to an omni-direction wheel system and methods for controlling the omni-direction wheel system. The omni-direction wheel system includes a plurality of suspension systems that operate independently of one another. Each suspension system may include an electromagnetic steering hub configured to rotate a wheel 360 degrees about a vertical axis based on a polarity of an electromagnetic signal applied to the electromagnetic steering hub. The suspension system may further include an in-wheel motor configured to rotate with the wheel and drive the wheel about a horizontal axis.

A revolving shelf system including side plates to be mounted on opposite side walls of a cabinet, a drive track on a face of each of the side plates, a plurality of guide tracks on the faces of the side plates, a plurality of shelves, a drive pin arranged on each end of the shelves, and configured to extend respectively into each of the drive tracks, a plurality of guide pins arranged on each end of the shelves, and configured to extend respectively into corresponding ones of the guide tracks, a drive chain arranged in each of the side plates to respectively drive the drive pins, and a motor to transmit driving power to the drive chains, wherein the shelves move with a rotation of the drive chains, and the drive and guide pins remain extended into the respective drive and guide pin tracks at any position of the shelves.

A cabinet system arranged to allow access to floor space underneath, the system including two side walls having front and rear edges, at least one door arranged proximate the front edges of the side walls and configured to be openable to access an area between the side walls; and a bottom panel arranged between the two side walls and configured such that at least a portion of the bottom panel is selectively movable to at least partially expose a floor space extending back from the front edges of the side walls.

A modular cabinet system including a cabinet shell configured with an open front space, a cabinet insert configured to be selectively installed in, and removed from, the cabinet shell by being passed through the open front space, a pair of first slide members respectively provided to each inner side surface of the cabinet shell, and a pair of second slide members respectively provided to each outer side surfaces provided proximate each side of the cabinet insert, wherein the respective first slide members are configured to interact with the corresponding second slide members to guide the cabinet insert into, and out of, the cabinet shell.

The present invention relates to a castor wheel structure, comprising a wheel part (18) and a castor wheel house (28), on which a transition element can be mounted, such as a spindle structure (1) or a flange structure (2), which again can be mounted on equipment that is to be made mobile, which wheel part (18) is unilaterally suspended and arranged about a substantially horizontal shaft on the castor wheel house (28).

A swivel trailer is described that can include a swivel hitch and swivel axle configuration which prevents a vehicle and trailer from jackknifing.

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.
