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.

A wheel pad for moving an object across a surface having non-planar obstructions to allow movement of the object across the surface. The wheel pad has a contact pad and a load bearing assembly. The contact pad has an outer skin enclosing a fluid and a torus bearing. The torus bearing has a plurality of bearings, with each adjacent bearing rotatably joined by a connector that allows the bearings to independently rotate. The load bearing assembly has a load transfer mechanism and a load transfer device. The load transfer mechanism has a plurality of recirculating bearings moveably positioned inside a ball chamber. The load transfer device interacts with, but moves independently of, the load transfer mechanism to transfer the weight of the object to the contact pad, which weight is transferred to a lower surface thereof by the fluid and torus bearing to provide omnidirectional movement for the wheel pad.

A patient support apparatus includes a base having a length and including a plurality of caster wheels enabling movement of the patient support apparatus across a floor surface. An auxiliary wheel support structure is secured to the base and rotatably supports at least one non-castered auxiliary wheel about a rotational axis transverse to the length of the base for engagement with the floor surface. The auxiliary wheel support structure may be configured to support the auxiliary wheel and to enable movement of the auxiliary wheel out of engagement with the floor surface to a non-engaged position wherein the at least one auxiliary wheel is out of engagement with the floor surface. A control apparatus is in communication with and moves the at least one auxiliary wheel between at least one deployed position and a non-engaged position.

The present invention provides a robot which is suitable for travel through a pipeline. The inventive robot comprises at least one tracked drive means and at least one roller means that can swivel about an axis substantially normal to a rolling axis thereof, wherein said at least one tracked drive means and at least one roller means are provided with magnetic means for generating a magnetic adhesion force between the robot and an internal wall of the pipeline.

The present invention provides one or more carrier devices capable of varying contact damping with pressured displacement. The device is configured to be installed on mechanical force-receiving structures that have rolling wheels, rolling balls or slidably displaceable terminal block structure, carrying devices and transportation devices for humans or objects. When receiving pressure smaller than a set value, the device provides low contact damping and is thus easy to move. On the other hand, when receiving pressure greater than the set value, it provides high contact damping so as to prevent slip and thereby ensure safe placement. In addition, when receiving pressure smaller than the set value, the device has its pre-stressed structure generate modulation to displacement corresponding to the size of the pressure it receives for the purpose of shock absorbency.

A universal rotating module is provided. The universal rotating module comprises a suspension carrier, a top cover, a globular element, and a plurality of cushion members. The suspension carrier includes a through hole and a plurality of first fixing portions beside the through hole. The top cover includes a plurality of second fixing portions. The globular element is disposed between the suspension carrier and the top cover. A portion of the globular element passes through the through hole. Each of the cushion members is correspondingly connected with the first fixing portion and the second fixing portion.

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 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.

A wheel adapter to convert a storage container to a wheeled storage container is provided. The wheel adapter comprises a mounting bracket attachable to the storage container. The mounting bracket comprises a first leg configured to engage a bottom surface of the storage container, and a second leg configured to engage a side surface of the storage container. The second leg comprises a wheel coupling. The wheel adapter also includes a wheel rotatably connected to the wheel coupling. The wheel is constructed and arranged for rotation about an axis to provide rolling support of the storage container on the ground.
