Disclosed is a wheel carrier for a suspension of a motor vehicle; and a motor vehicle comprising the wheel carrier. In a preferred system, the wheel carrier comprises a first carrier segment configured to carry a wheel of the motor vehicle at a wheel center; and a second carrier segment configured to couple the first carrier segment with a vehicle body of the motor vehicle. The second carrier segment comprises at least one groove, and the first carrier segment comprises for each groove a corresponding sliding pin configured to slidingly engage the respective groove such that the pin slides along the groove under vertical and/or horizontal displacements of the wheel center with respect to the second carrier segment.

A medical apparatus according to an embodiment of the present invention includes: a medical device; and a plurality of caster units, disposed below the medical device, for supporting the medical device to be movable, wherein each of the plurality of caster units includes: a wheel part; and a shock absorbing member which is configured to support the wheel part and to absorb the shock applied to the wheel part, wherein the shock absorbing member includes: a wheel fixing member for fixing the wheel part; a body fixing member which surrounds the wheel fixing member and is fixed to the medical device; and a cushioning member which is disposed between the wheel fixing member and the body fixing member and is capable of elastic deformation, wherein the shock absorbing member includes: a first deforming part extending in the vertical direction; and a second deformation part extending, from an end of the first deformation part, in a direction different from the extending direction of the first deformation part.

A caster assembly comprises a caster wheel having an outer surface. A wheel support is coupled to the wheel to support the wheel for rotation about a rotational axis and for swiveling about a swivel axis. A brake assembly comprises a brake having a cammed wheel engaging surface shaped to engage the outer surface of the wheel and a brake actuator to move the brake relative to the wheel from an unbraked position to a braked position in which the brake limits rotation of the wheel about the rotational axis. The cammed wheel engaging surface is arranged to articulate relative to the wheel support. The cammed wheel engaging surface articulates relative to the wheel support in response to the wheel rotating about the rotational axis after the brake is initially placed in the braked position such that the cammed wheel engaging surface more deeply engages the wheel with rotation of the wheel about the rotational axis.

The invention provides a caster including two wheels, a central frame member, and a mount member. The two wheels are mounted on the mount member. The caster has a hybrid bearing arrangement comprising both a rolling bearing and two slide bearings. The rolling bearing is located between the central frame member and the mount member and is configured to enable the caster to roll along a straight line with each of the two wheels rotating in a common direction about a first axis. Each of the two slide bearings is located between the mount member and a tread portion of a respective one of the two wheels. The slide bearings are configured to enable the two wheels to simultaneously rotate in opposite directions when the caster swivels about a second axis orthogonal to the first axis. In some embodiments, the caster is a hubless caster.

A payload platform includes a platform and a castor assembly coupled to the platform. The castor assembly includes a body, a first wheel coupled to the body, and a second wheel coupled to the body. The first wheel and the second wheel are individually actuatable. A sensor is coupled to the body. A control unit is operably coupled to the sensor and operably coupled to the first wheel and to the second wheel. The sensor detects an area surrounding the platform, determines presence of obstacles, and transmits a signal to the control unit corresponding to the area surrounding the platform. The control unit directs the first wheel and the second wheel to rotate in a prescribed manner so as to achieve a prescribed movement of the platform.

A caster for equipment and furniture, the caster comprising a support element including a top element and a base element, wherein the top element includes an attachment bolt configured to attach the caster and the base element includes a wheel axle that supports at least one wheel, wherein a replaceable substantially circumferential one-piece support element cover made from a synthetic material that provides a continuous design surface is arranged at the support element.

A caster may include a shaft, a first elastic ring, a C-shaped ring, and a second elastic ring. The shaft has one end inserted and secured in a wheel, and a first rod is extended from the other end of the shaft, and a second rod protrudes from an end of the first rod. The diameter of the first rod is larger than that of the second rod, and an end of the second rod comprises a flexible portion. The shaft only needs to be processed to form the second rod and the flexible portion, and the first elastic ring and the second elastic ring which are identical are adapted to be formed through the same mold so as to save the manufacturing cost.

The present invention relates to an adjustable height table base with a transport mechanism, and in particular to a transport mechanism selectably operable in a grounded position, a low transport position and a high transport position. The table has a base that is adjustable in length with a crank. A top is supported by a table frame, which allows the top to be locked in a horizontal or vertical position. Four legs can be provided each having a pad at a distal end. A transport mechanism is also provided. The transport mechanism has a caster assembly with four casters and has an extension assembly that is extendable along its longitudinal axis to move that table between the grounded position, low transport position and high transport position. The extension assembly is operable under force of gravity and used by lifting or tilting anywhere radially about the table at selected distances.

A system includes (i) a caster having a first stem portion with a first stem portion connection configuration; and (ii) a set of second stem portions having an identical second stem portion connection configuration but having outer dimensions differing from outer dimensions of another second stem portion in the set of second stem portions. The caster first stem portion connection configuration is adapted to mate with the second stem portion connection configuration of the second stem portions in the set of second stem portions.

The present invention relates to an omnidirectionally moving wheel and a robot using the same, and the omnidirectionally moving wheel comprises: a cylindrical body of which both ends are opened; inner wheels, each of which have at least a part accommodated in the body, and which are respectively fixed at the both open ends of the body so as to rotate around a first rotating axis; an outer wheel provided on the outside of the body and rotating around a second rotating axis, which intersects the first rotating axis, wherein the outermost points of the inner wheels and the outer wheel are formed at the same distance from the center of the body.
