Patent number: 11963916Abstract: A track assembly for a patient transport apparatus, comprising a rail defining a first end and a second end, an axle defining an axis, a roller supported about the axis, and a belt engaging roller and arranged for movement relative to the rail in response to rotation of the roller. A guide supports the axle for movement. A keeper coupled to the axle is operable between a disengaged configuration to permit movement of the axle, and an engaged configuration to restrict movement. A brace is operatively attached to the rail adjacent to the guide. A tensioning cam coupled to the axle defines a plurality of relief catches arranged for engagement with the brace. The relief catches are each shaped to remain in selective engagement with the brace effected by concurrent movement of the axle and the tensioning cam to tension the belt against the roller in the disengaged configuration.Type: GrantFiled: December 23, 2020Date of Patent: April 23, 2024Assignee: Stryker CorporationInventors: Brian J.
