Provided herein is an apparatus including a top member configured to couple with an anatomical appendage or a structure thereof; a bottom member rotatably attached to the top member; and a movement-enabling means for enabling the apparatus to move across a surface substantially without interruption, wherein the movement-enabling means comprises a turntable bearing between the top member and the bottom member, and a rolling mechanism about a bottom surface of the bottom member.

主权项

1. An apparatus comprising
a top member comprising two vertical sections joined together by a horizontal section, where the top member is configured to couple to a handle with two ends, such that each end of the handle attaches to one of the vertical sections of the top member; two bearings, each bearing connected between the end of the handle and the vertical section of the top member, such that the bearing surrounds a circumference of the handle, allowing the handle to rotate with respect to the top member; the handle being configured to couple to an anatomical appendage; a bottom member rotatably attached to the top member and a turntable bearing between the top member and the bottom member for a multidirectional rotation movement; and at least one rolling mechanism having a ball transfer bearing and a plurality of recirculating load transmitting balls about a bottom surface of the bottom member, wherein the rolling mechanism is assembled by adding the recirculating load transmitting balls in a plurality of layers to a top housing and the ball transfer bearing is placed on top of the recirculating load transmitting balls in the bottom housing and wherein the top housing and the bottom housing is snap fitted without any openings to form the rolling mechanism.
