The universal wheel includes a base member, a vertical axle, a lift member, and a wheel member. The lift member adjusts the universal wheel's height. A first driving element, a second driving element, and an engaging element are configured on the base member and the wheel member. The first driving element for turning the base member laterally within 360 degrees. The second driving element is for rolling the wheel member around its lateral axle. The engaging element couples or decouples an external shaft with the lateral axle of the wheel member. As such, through the first and second driving elements, and the engaging element, the universal wheel can control a height from the ground and can be rolled forward, laterally, obliquely, turned 360 degrees when standing in place, or in a combination of these operations.

In a heavy duty orbital caster assembly that includes a rotatable wheel unit joined to a transfer plate that pivots about a mounting post extending from a mounting plate adapted to be secured to the bottom surface of an object, the improvement comprising a pair of roller bearing assemblies that extend upwardly from the upper surface of the transfer plate adjacent to the caster wheel post as it extends through its bearing. The rollers impinge on the lower surface of the mounting plate, and serve to transfer some of the load of the supported object directly to the caster wheel, enabling the support of very heavy loads.

In order to form a mobile wheel base, a stem caster adapter or a wheel assembly are attached to the bottom of a platform support or a container such as a cardboard carton are provided. The adapter has a body with a cylindrical recess open at the bottom surface adapted to receive and engage the stem of the caster. In the wheel assembly, a wheel or roller is rotatably attached to the bottom of the body. Both the adapter and wheel assembly have a cylindrical member extending from the top surface of the body with oppositely extending protrusions forming a bayonet-type mount. The mount is received within an opening in the bottom of the platform support or container and then rotated to attach the adapter or wheel assembly to the platform support or container.

A system for supporting or positioning a patient before, during, or after a medical procedure can include a platform configured to support at least a portion of a patient. A support column can be positioned beneath the platform. A base can be positioned beneath the support column and configured to support the support column. The base can include at least one drive wheel configured to contact a ground surface and move the platform with respect to the ground surface. A drive assist user interface module can be operatively connected to the at least one drive wheel. The drive assist user interface module can be configured to permit an operator of the system to selectively control movement of the at least one drive wheel. The drive assist user interface module can be part of or be attached to an attachment that includes a plate having a top surface. In one configuration, the top surface of the plate can be configured to extend parallel with a top surface of the platform when the attachment is attached to the platform.

A rough terrain cart for a wheel chair includes a frame operable to support a wheel chair and a wheel chair user. A pair of cart drive wheels are rotationally mounted to the frame. A locking mechanism is engaged with the frame. The locking mechanism is operable to secure the wheel chair to the cart. A rotational mechanism is engaged with the frame. The rotational mechanism is configured to support a pair of wheel chair drive wheels of the wheel chair and is operable to enable the wheel chair drive wheels to rotate when the wheel chair is secured to the cart by the locking mechanism. A transmission system is engaged with the frame. The transmission system is connectable to the wheel chair drive wheels. The transmission system is operable to transmit torque from the wheel chair drive wheels to the cart drive wheels.

A removable transport caster assembly secured to side to side beams or front to back beams in a data center cabinet in a data center. The removable transport caster assembly is temporarily installed on the cabinet to enable the cabinet to be relocated to another location in the data center. The removable transport caster assembly includes a transport caster and a transport caster bracket secured to the transport caster. The transport caster has a mounting plate, a mounting bracket extending from the mounting plate, a lifting plate pivotally connected to the mounting plate, a lifting lever pivotally connected to the mounting bracket and a wheel assembly. The transport caster bracket secures the transport caster to the cabinet when relocation of the cabinet is desired.

A trailer for a motor vehicle includes a bed, a trailer tongue, a tongue frame, and a plurality of swivel frames. The bed has a front end and a rear end, and is configured to receive a load to be transported by the trailer. The trailer tongue is configured to be rigidly coupled to a hitch, wherein the hitch is rigidly affixed to a motor vehicle. The tongue frame operable couples the trailer tongue to the bed proximate the front end in a laterally rigid manner, such that the bed is substantially inhibited from lateral movement with respect to the hitch. Each of the plurality of swivel frames is operably rotatably coupled to the bed, and includes at least one wheel rotatably attached thereto.

An object of the invention is to provide a personal mobility that is able to turn by movement of the gravitational center of a passenger, without individually controlling each motor that drives the left and right wheels, and without using any special parts. The personal transporter includes left and right driving wheels (21) as front wheels, left and right casters (22) as rear wheels, and two motors (31) for independently driving the left and right driving wheels (21). By giving a camber angle, in which an upper part inclines inward when viewed from the front, with respect to the left and right casters (22), the torque or the applied voltage of the two motors (31) is the same, the caster (22) rotates in the direction of movement of gravitational center to act as a steering wheel, and it is possible to turn a personal transporter in the movement direction of the gravitational center.

A system for supporting or positioning a patient before, during, or after a medical procedure can include a platform configured to support at least a portion of a patient. A support column can be positioned beneath the platform. A base can be positioned beneath the support column and configured to support the support column. The base can include at least one drive wheel configured to contact a ground surface and move the platform with respect to the ground surface. A drive assist user interface module can be operatively connected to the at least one drive wheel. The drive assist user interface module can be configured to permit an operator of the system to selectively control movement of the at least one drive wheel. The drive assist user interface module can be part of or be attached to an attachment that includes a plate having a top surface. In one configuration, the top surface of the plate can be configured to extend parallel with a top surface of the platform when the attachment is attached to the platform.
