Publication number: 20260053684Abstract: 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.Type: ApplicationFiled: November 3, 2025Publication date: February 26, 2026Applicant: Stryker CorporationInventors: Nathan W. Matheny, Daniel V. Brosnan, Melvin Gottschalk, JR., Cory P. Herbst, Brandon David Naber, Kelly Sandmeyer, Scott Zufall, Trey Thomas Pfeiffer, Patrick Grossman, Tyler Wright

Publication number: 20250332043Abstract: 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.Type: ApplicationFiled: July 9, 2025Publication date: October 30, 2025Applicant: Stryker CorporationInventors: Trey Thomas Pfeiffer, Nathan W.

Publication number: 20060016287Abstract: A shifter for controlling a transmission of a motor vehicle includes a base structure and a shift lever that is movably mounted to the base structure for movement between a plurality of control positions. At least one of the control positions comprises a NEUTRAL position. The shifter further includes a shift gate having a plurality of notches corresponding to the control positions. The shift gate is positioned on a selected one of the base and the shift lever. The shifter further includes a movable pawl member selectively engaging the notches of the shift gate to restrict movement of the shift lever relative to the base structure. The pawl member is biased into engagement with the shift gate. A movable retaining member selectively engages the shift gate to retain the shift lever in the NEUTRAL position wherein the retaining member is biased out of engagement with the shift gate.Type: ApplicationFiled: May 2, 2005Publication date: January 26, 2006Inventors: Patrick Grossman, Robert De Jonge
