Maneuverable ergonomic trailer stands are disclosed. An example portable trailer stand includes a frame having an upper ledge; an extendible leg coupled to the frame, the upper ledge being vertically movable to selectively engage and disengage an underside of a trailer parked on a driveway based on movement of the extendible leg relative to the frame; a wheel connected to the frame, the wheel to remain at a substantially fixed distance from the upper ledge as the upper ledge is vertically moved

Mobile folding restaurant booth style benches are provided, which may be arranged in opposed pairs to form restaurant style booths. An individual bench incorporates a mechanism for shifting the weight of the bench between a mobile base, which may be supported by swivel casters, and a stationary base, which may be supported by non-slip feet, actuated by pivoting a bench seat down from a folded storage position to an unfolded seating position. The weight shifting mechanism may include an engagement member, which is initially spaced apart from an actuator at a folded angle of the seat, and which contacts and begins transmitting force and movement to the actuator at a partially unfolded angle of the seat. Preferably, the bench further includes a biasing component that biases the stationary base upward relative to the mobile base.

A lift mechanism for a wheel assembly includes a lever arm having a first axis of rotation, and a first torque transfer plate having a second axis of rotation coincident with the first axis of rotation. A lift block is engageable by the first torque transfer plate and has a first angularly disposed surface and a resting surface adjacent to the first angularly disposed surface. The lift mechanism is configured such that rotation of the lever arm causes the first torque transfer plate to rotate into engagement with the lift block, thereby causing linear motion of the lift block. The wheel assembly is raised and lowered by contact between a portion of the wheel assembly and the first angularly disposed surface of the lift block and held in a raised position when the portion of the wheel assembly is positioned with respect to the resting surface.

A wheel adapter for a cargo container includes a wheeled adapter body. A container connector on the adapter body is configured for connection to the cargo container. A container elevation bolt threadably engages the adapter body. The container elevation bolt is selectively adjustable to correspondingly adjust an elevation of the adapter body and raise the cargo container for transport.

A mobility apparatus. The mobility apparatus may include a continuous fixed-length rail attached horizontally to a bottom structural member of the front or the rear of a server rack. The continuous fixed-length rail exceeds a width of the server rack by an equal amount on either side of the server rack. The mobility apparatus also includes a lower rail portion attached to a lower edge of the continuous fixed-length rail; a raised rail portion attached to an extended length of each portion of the continuous fixed-length rail; and at least one wheel attached to an underside of each end of the extended length of the continuous fixed-length rail.

Maneuverable ergonomic trailer stands are disclosed. An example portable trailer stand includes: a frame having an upper ledge, a post, and a lower subframe, the lower subframe connected to the upper ledge via the post; an extendible leg coupled to the post independent of the lower subframe, the upper ledge being vertically movable based on movement of the extendible leg relative to the upper ledge, the post, and the lower subframe of the frame; and a wheel connected to the frame via the lower subframe such that the wheel is to move with the upper ledge as the upper ledge is vertically moved.

An actuating mechanism useful for retracting and extending furniture glides allows a minor lifting movement to actuate the caster/glide from a stored position to an extended, operative position. The same motion permits the caster/glide to be retracted to its stored position.

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.

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.

A caster assembly for use with varies structures, including ladders and elevated platforms is provided. In one embodiment, the caster assembly includes a first wheel coupled with a first bracket and configured to rotate about a first axis relative to the first bracket. A shaft is coupled to the first bracket as well as to a second bracket. The first bracket is rotatable relative to the second bracket about a second axis, which may be coincident with, or parallel to, an axis of the shaft. A third bracket is coupled with the shaft and is rotatable about the second axis, the third bracket being selectively locked in at least two positions relative to the second bracket. A second wheel is coupled with the third bracket, the second wheel being rotatable relative to the third bracket about a third axis.
