Abstract: A stairlift includes a rail and a carriage. The carriage includes a frame, a central drive unit mounted to the frame, the central drive unit including a drive motor and a drive gear, a yoke assembly pivotably mounted to the frame, and a first bogie unit attached to the yoke assembly and a second bogie unit attached to the yoke assembly, wherein each bogie unit includes a bogie socket mounted to the yoke assembly, and a bogie ball spherically pivotable within the bogie socket, the bogie ball including a plurality of bogie ball rollers configured to hold the bogie ball to the rail, and further wherein the plurality of bogie ball rollers are configured to maintain the bogie ball in a generally perpendicular travel orientation relative to the rail.

Abstract: A rail segment for a stairlift and its method of formation are provided. The rail segment includes an elongate tube made of a first material, the tube comprising a first end, a second end, and a longitudinal retaining slot extending from the first end to the second end; a rack made of a second material, the rack comprising a first end and a second end, wherein the rack is held within the retaining slot; and anchor securing the rack within the retaining slot to the tube at or adjacent to ends of the tube.

Abstract: A mechanical barrier recipient verification system including a combination lock assembly having a housing carrying a combination lock mechanism. The housing forms an aperture. The lock mechanism selectively receives and captures a post inserted through the aperture. Further the lock mechanism is configured to provide combination unset and set states; unlocked and locked positions; and correctly and incorrectly entered code arrangements. Following insertion of the post into the aperture and with the lock mechanism in the locked position, the post is retained by the lock mechanism regardless of the correctly or incorrectly entered code arrangement.

Abstract: A collapsible bulk bin has floating hinges with no moving parts that allow the walls of the bin to lay flat on top of each other. The collapsible bulk bin can include removable support feet that may be easily replaced thereby extending the usable life of the collapsible bulk bin.
