Abstract
A patient transport apparatus including a support structure movable between a chair configuration for traversing floor surfaces and a stowed configuration for storage. A seat section is pivotably coupled to the support structure. A caster assembly includes a pin coupled to the support structure and defining a swivel axis, a caster frame arranged to pivot about the swivel axis between a plurality of caster orientations, a wheel coupled to the caster frame and arranged for engagement with the floor in the chair configuration, and a biasing mechanism interposed between the caster frame and the pin. The biasing mechanism urges the caster frame toward a stowed caster orientation in response to disengagement between the wheel and floor surfaces occurring as the support structure moves from the chair configuration to the stowed configuration.
