ABSTRACT:
The door on an environmental chamber is provided with a single throw, multi-fingered over-center latching mechanism. The latching fingers extend from a common pivoting assembly, and are operated as a unit by a single handle. A hook on the end of each finger engages a post on the chamber housing. As the handle is operated, the over-center action of the pivoting assembly pulls the door towards the housing causing the gasket to seat. The over-center structure biases the latching mechanism in the latched position.
