A shock absorbing caster system includes an inner-bearing, a flexible-hub, and outer-rim, and a cylindrical disc. The inner-bearing is configured as a roller-bearing and fixed to the flexible-hub. The inner-bearing is further surrounded by the outer-rim. The inner-bearing is fixed to the flexible-hub and to the outer-rim by a bonding process. The cylindrical disc is configured as a tire and further circumferentially affixed to the other-rim. The shock absorbing caster is useful for providing a caster wheel having a flexible hub with shock absorbing properties for use with luggage and other suitable applications.

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.

There is provided a spring-powered drive apparatus including a casing (102), an output shaft (103) mounted on the casing (102) in a relatively rotatable manner, a one way clutch (112) externally fitted on the output shaft (103) in the casing (102) and, a spiral spring (105, 107) housed in the casing and wound by turning of the output shaft (103) in the direction in which the one way clutch (112) transmits torque. Thus, there can be provided a compact spring-powered drive apparatus and a self-propelled caster that can be applied to a work cart or the like.

A furniture rotary system for a piece of furniture is provided. The furniture rotary system is forming a sliding rotary connection between a rotational member and a stationary member wherein said furniture rotary system comprises at least one sliding surface being coated with a lacquer comprising a resin, wherein said lacquer in turn is at least partly coated with a lipophilic composition coating to provide a slide layer with a lowered friction.

An article movement system includes an article and at least one ball wheel. The article has first and second article surfaces meeting at a first article edge. The ball wheel is located along the first article edge and includes a ball, a bearing arrangement and a shell. The ball engages a surface underlying the article, the bearing arrangement supports the ball for omni-directional rotational movement, and the shell is located along the first article edge and contains the ball and the bearing arrangement. The shell defines a non-circular ball opening through which a portion of the ball extends to contact the underlying surface. The article, the bearing arrangement and the shell are configured such that the ball wheel is able to support the article for omni-directional rolling motion over the underlying surface with either of the first and article surfaces parallel thereto, and at any orientation therebetween.

A pallet moving system includes a pallet dolly puller, and a pallet dolly with a guiding structure thereon permitting and facilitating the blind engagement and disengagement of the dolly puller to the pallet. The dolly puller includes caster wheels, a handle, and at least one projecting portion configured to mateably couple with recessed portions on the underside of the pallet dolly in order that the pallet dolly may be moved and readily re-positioned even in confined spaces.

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 wheel for a single or double caster for furniture or hospital beds or medical equipment, the wheel comprising: a rim; a tire; and a wheel bearing centrally arranged in the rim, wherein a running surface of the tire envelops the rim, and wherein the running surface of the tire includes a plurality of bonded spokes which are at least in contact the wheel bearing. The wheel is producible in a simple manner with short cycle times while having good thermal conductivity.

An apparatus includes first and second side portions, and a horizontal portion disposed between the first and second side portions. Each side portion includes an inner wall joined to the horizontal surface, an exterior wall, and a top portion connected that define a volume within the side portion. Each side portion also includes first and second wheels within the volume, the first and second wheels having a raised wheel position and a lowered wheel position. Each side portion also has an arm coupled to the outer wall of the side portion, the arm having a first arm position and a second arm position. Movement of the arm from the first arm position to the second arm position causes the wheels to move from the raised wheel position to the lowered wheel position.
