Claim:
1. An apparatus comprising: a caster comprising: wherein one of the centering element and the locking element is configured to pivot about a pivot axis and hence comprise a pivoting element, and wherein the other of the locking element and the centering element is configured to remain pivotally stationary about the pivot axis and hence comprise a pivotally stationary element, the pivotally stationary element being further configured to be biased along the pivot axis toward the pivoting element by a biasing force from the biasing element; wherein the biasing element, through interaction between the end camming surface and the locking element, pivotally urges the locking element relative to the centering element toward at least a first orientation wherein the at least one locking notch of the end camming surface captures the locking element such that the pivoting element is restricted from pivoting about the pivot axis until the biasing force from the biasing element is at least one of operatively removed or countered; a disengagement device configured to axially slide the centering element away from the locking element along the pivot axis such that the centering element does not contact the locking element.
