A patient transport apparatus for transporting a patient. A seat section is pivotably coupled to a support structure about a seat axis. A front wheel is operatively attached to a front strut of the support structure, and a carrier is arranged for movement relative to the support. The carrier includes a shaft defining a wheel axis, a rear wheel supported for rotation about the wheel axis, a track having a belt, and a hub supporting the shaft and the track for concurrent pivoting movement about a hub axis defined by a upright of the support structure. The hub axis extends through a plane intersecting the seat axis, fixed relative to the upright, and defining opposing first and second sides. Movement of the carrier from a chair configuration to a stair configuration simultaneously deploys the track and moves the wheel axis from the first side to the second side.

Patient transport apparatus for traversing stairs

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.
