Steam sterilizer door alignment assembly with roller assemblies
A newly granted patent (Publication Number: US11986564B2) discloses a door alignment assembly designed to align a movable door relative to an opening. The assembly consists of multiple roller assemblies strategically positioned along the edges of the door to ensure proper alignment as the door transitions between open and closed positions. Each roller assembly includes a shaft, a cylindrical roller with outer annular surface profile, and biasing elements on either side of the roller, allowing axial movement along the shaft. This setup enables the door to move along a specific path in a plane while also permitting limited movement perpendicular to the plane.
Furthermore, the patent details the use of helical springs as the biasing elements, enhancing the functionality of the door alignment assembly. The surface profile of the roller assemblies features a recess, complemented by a tapered edge on one side of the door to facilitate smooth entry. Additionally, the annular surface profile of the roller engages a corresponding surface profile on the lateral edge of the door, ensuring a secure alignment. The biasing elements apply forces in opposite directions along the shaft's axis, allowing for precise control over the door's movement. Overall, this innovative door alignment assembly offers a practical solution for maintaining door alignment while enabling smooth and controlled motion for improved functionality.
